THE FUND

INVESTMENT GOAL

The Fund seeks long-term capital appreciation by investing, under normal market conditions, at least 80% of its total net assets (plus any borrowings for investment purposes) in stocks issued by companies from at least three countries outside the United States.

PRINCIPAL INVESTMENT STRATEGIES

While the Fund's investments are not limited by market capitalization, the Fund intends to invest primarily in companies considered to be large and well-established, based on standards of the applicable country or foreign market. Most of the Fund's stocks will be denominated in foreign currencies. This means that their value will be affected by changes in the exchange rate between the U.S. dollar and foreign currencies.

The Fund intends to invest principally in the equity securities of companies located in the following countries or regions: Australia, Brazil, Canada, China, Denmark, Finland, France, Germany, Hong Kong, India, Ireland, Italy, Japan, Mexico, The Netherlands, New Zealand, Norway, Singapore, South Korea, Spain, Sweden, Switzerland, Taiwan, Thailand and the United Kingdom.

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).

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. 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.

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. 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.

Investment in emerging markets is 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 is also subject to foreign currency risk. In managing currency exposure, the Fund may enter into forward currency contracts. A forward currency contract involves an agreement to purchase or sell a specified currency at a specified future price set at the time of the contract. When the Fund enters into a contract for the purchase or sale of a security denominated in a foreign currency, it may desire to "lock in" the U.S. dollar price of the security. The Fund will only enter into forward contracts for hedging and not for purposes of speculation. Under normal market conditions, no more than 25% of the Fund's assets may be committed to currency exchange contracts.

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.

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

THE FUND

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.

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, negatively impact the investment returns of other shareholders. Although the Fund has adopted certain policies and methods intended to identify and to 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, C and D shares, including sales charges, compare with those of broad measures of market performance for 1 year, 5 years and 10 years. All information in this prospectus relating to the Fund for periods prior to October 10, 2005, including the performance information shown below, is that of Columbia International Stock Fund, Inc., 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. 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 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 Morgan Stanley Capital International Europe, Australasia and Far East Index (MSCI EAFE Index) and the Morgan Stanley Capital International All Country World Ex US Index (MSCI AC World Ex US Index). The MSCI EAFE Index is an unmanaged index representing major stock markets in Europe, Australasia and the Far East. The MSCI AC World Ex US Index is also an unmanaged index representing both developed and emerging markets of 49 countries, excluding the United States. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed.

The Fund's year-to-date total return         For the periods shown in bar chart:
through June 30, 2005 (Class A) was -2.12%.  Best quarter: 4th quarter 1999, +34.96%
                                             Worst quarter: 3rd quarter 2002, -18.71%

(1) Class A is a newer class of shares. Its performance information includes returns of Class Z shares (the oldest existing 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 October 1, 1992.

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 an investor's 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 administrative costs including pricing and custody services.

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 or your financial advisor 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 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.

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 or Class C shares. Purchases of $1 million or more can be made only in Class A shares. Based on your personal situation, your investment advisor can help you decide which class of shares makes the most sense for you.

The Fund also offers two additional classes of shares, Class G and Z shares, exclusively to certain institutional and other investors. Class G and Z shares are made available through separate prospectuses provided to eligible institutional and other investors.

CLASS A SHARES Your purchase 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, 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


11

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 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.

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. In addition, if you acquired Class A shares of the Fund by exchange from another fund, you will not be permitted to exchange those shares into another fund for 30 calendar days. You may, however, redeem those shares at any time. 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" in this Prospectus 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

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 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 1-800-345-6611 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.

YOUR ACCOUNT

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, the Fund will generally 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, the Fund imposes 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 generally 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.

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 the 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.

The 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 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 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


16

YOUR ACCOUNT

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 the Fund's distributor marketing and other fees to support the sale and distribution of Class B, C and D shares. The plan also permits the Fund to pay your financial advisor fees for certain services provided regarding your Class A, B, C and D shares. 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 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 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

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 (typically Monday through Friday). Shares are not priced on 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 caption "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.


18

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, generally based on the number of shares you own at the time these distributions are declared.

DISTRIBUTION OPTIONS The Fund declares and pays dividends at least 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, or if you do not cash a distribution check within six months of the check date, the distribution 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 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 0.85% of average daily net assets of 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


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, 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.

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.

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 transferred the CDSC Lawsuit to the MDL.

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, reinvesting all dividends and distributions and converting Class B to A shares after eight years. The annual expense ratio used for the Fund, which is the same as that is stated in the Annual Fund Operating Expenses tables, is reflected in the chart and is net of any fee waiver or expense reimbursement.

THE FUND

INVESTMENT GOAL

The Fund seeks long-term capital appreciation by investing, under normal market conditions, at least 80% of its total net assets (plus any borrowings for investment purposes) in stocks issued by companies from at least three countries outside the United States.

PRINCIPAL INVESTMENT STRATEGIES

While the Fund's investments are not limited by market capitalization, the Fund intends to invest primarily in companies considered to be large and well-established, based on standards of the applicable country or foreign market. Most of the Fund's stocks will be denominated in foreign currencies. This means that their value will be affected by changes in the exchange rate between the U.S. dollar and foreign currencies.

The Fund intends to invest principally in the equity securities of companies located in the following countries or regions: Australia, Brazil, Canada, China, Denmark, Finland, France, Germany, Hong Kong, India, Ireland, Italy, Japan, Mexico, The Netherlands, New Zealand, Norway, Singapore, South Korea, Spain, Sweden, Switzerland, Taiwan, Thailand and the United Kingdom.

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).

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. 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.

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. 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.

Investment in emerging markets is 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 is also subject to Foreign Currency Risk. In managing currency exposure, the Fund may enter into forward currency contracts. A forward currency contract involves an agreement to purchase or sell a specified currency at a specified future price set at the time of the contract. When the Fund enters into a contract for the purchase or sale of a security denominated in a foreign currency, it may desire to "lock in" the U.S. dollar price of the security. The Fund will only enter into forward contracts for hedging and not for purposes of speculation. Under normal market conditions, no more than 25% of the Fund's assets may be committed to currency exchange contracts.

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.

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.

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, negatively impact the investment returns of other shareholders. Although the Fund has adopted certain policies and methods intended to identify and to 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

Because Class G shares have not been offered for a full calendar year, the information provided in the bar chart below shows the Fund's calendar year total returns (before taxes) for its Class B shares from November 1, 2002 until December 31, 2004, and prior to November 1, 2002 (the inception of Class B shares), Class Z shares. The performance table following the bar chart shows how the Fund's average annual total returns for Class B and Class Z shares, adjusted to reflect the sales charges of Class G shares, compared with those of a broad measure of market performance for 1 year, 5 years and 10 years. All information in this prospectus relating to the Fund for periods prior to October 10, 2005, including the performance information shown below, is that of Columbia International Stock Fund, Inc., 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 G 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 Morgan Stanley Capital International Europe, Australasia and Far East Index (the "MSCI EAFE Index") and the Morgan Stanley Capital International All Country World Ex US Index (the "MSCI AC World Ex US Index"). The MSCI EAFE Index is an unmanaged index representing major stock markets in Europe, Australasia and the Far East. The MSCI AC World Ex US Index is also an unmanaged index representing both developed and emerging markets of 49 countries, excluding the United States. 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 an investor's 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, 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 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 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 G 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.

CLASS G SHARES ARE SOLD ONLY TO INVESTORS WHO RECEIVED (AND WHO HAVE CONTINUOUSLY HELD) CLASS 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.

In certain circumstances, the sales charge may be reduced or waived, as described below and in the Statement of Additional Information.

CLASS G SHARES Your purchases of Class G shares are 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 A 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.


UNDERSTANDING CONTINGENT DEFERRED SALES CHARGES

Certain investments in Class 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.


HOW TO EXCHANGE SHARES

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 B shares acquired upon exchange of Class G shares may not be further exchanged for 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" 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 1-800-338-2550. 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, including the Fund, 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 generally 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.

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 the 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.

The 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 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 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


14

YOUR ACCOUNT

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 G shares and certain services provided to you by your financial advisor. The plan also permits the Fund to pay your financial advisor fees for certain services provided regarding your Class G shares. The annual fee for shareholder liaison services and administration support may equal up to 0.25%. The annual distribution fee may equal up to 0.65%. Distribution and service fees are paid out of the assets of this 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 A shares after eight years, eliminating a portion of these fees upon conversion. 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 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.

YOUR ACCOUNT

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 on 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 caption "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 declares and pays 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 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 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 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 0.85% of average daily net assets of the Fund.

PORTFOLIO MANAGERS

PENELOPE L. BURGESS, a Senior Vice President of Columbia Management, is a co-manager for the Fund and co-managed the Fund since July, 2004.

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


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 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.

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


19

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 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 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 Class A shares after eight years. The annual expense ratio used for the Fund, which is the same as that is stated in the Annual Fund Operating Expenses tables, is reflected in the chart and is net of any fee waiver or expense reimbursement.

THE FUND

INVESTMENT GOAL

The Fund seeks long-term capital appreciation by investing, under normal market conditions, at least 80% of its total net assets (plus any borrowings for investment purposes) in stocks issued by companies from at least three countries outside the United States.

PRINCIPAL INVESTMENT STRATEGIES

While the Fund's investments are not limited by market capitalization, the Fund intends to invest primarily in companies considered to be large and well-established, based on standards of the applicable country or foreign market. Most of the Fund's stocks will be denominated in foreign currencies. This means that their value will be affected by changes in the exchange rate between the U.S. dollar and foreign currencies.

The Fund intends to invest principally in the equity securities of companies located in the following countries or regions: Australia, Brazil, Canada, China, Denmark, Finland, France, Germany, Hong Kong, India, Ireland, Italy, Japan, Mexico, The Netherlands, New Zealand, Norway, Singapore, South Korea, Spain, Sweden, Switzerland, Taiwan, Thailand and the United Kingdom.

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).

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. 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.

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. 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.

Investment in emerging markets is 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 is also subject to Foreign Currency Risk. In managing currency exposure, the Fund may enter into forward currency contracts. A forward currency contract involves an agreement to purchase or sell a specified currency at a specified future price set at the time of the contract. When the Fund enters into a contract for the purchase or sale of a security denominated in a foreign currency, it may desire to "lock in" the U.S. dollar price of the security. The Fund will only enter into forward contracts for hedging and not for purposes of speculation. Under normal market conditions, no more than 25% of the Fund's assets may be committed to currency exchange contracts.

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.

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

THE FUND

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.

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, negatively impact the investment returns of other shareholders. Although the Fund has adopted certain policies and methods intended to identify and to 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 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 1 year, 5 years and the life of the Fund. All information in this prospectus relating to the Fund for periods prior to October 10, 2005, including the performance information shown below, is that of Columbia International Stock Fund, Inc., 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. 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 in the life of the Fund. 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.

The Fund's returns are compared to the Morgan Stanley Capital International Europe, Australasia and Far East Index (the "MSCI EAFE Index") and the Morgan Stanley Capital International All Country World Ex US Index (the "MSCI AC World Ex US Index"). The MSCI EAFE Index is an unmanaged index representing major stock markets in Europe, Australasia and the Far East. The MSCI AC World Ex US Index is also an unmanaged index representing both developed and emerging markets of 49 countries, excluding the U.S. 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 administrative costs including pricing and custody services.

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

SHAREHOLDER FEES(1) (PAID DIRECTLY FROM YOUR INVESTMENT)

Maximum sales charge (load) on purchases (%)
(as a percentage of the offering price)                                   0.00
------------------------------------------------------------------------------
Maximum deferred sales charge (load) on redemptions (%)
(as a percentage of the lesser of purchase price or
redemption price)                                                         0.00
------------------------------------------------------------------------------
Redemption fee (%)
(as a percentage of amount redeemed, if applicable)                       2.00(2)(3)

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

(2) There is a $7.50 charge for wiring sale proceeds to your bank.

(3) A redemption fee of 2% of redemption proceeds will be imposed on redemptions (including redemptions by exchange) of Class Z shares of the Fund that were owned for 60 days or less. The redemption fee will be applied assuming that shares held the longest are redeemed first. Shares purchased prior to February 15, 2003 are not subject to the redemption fee. The fee may be waived in certain circumstances, as described under "Fund Policy on Trading of Fund Shares." For Fund shares held through certain intermediaries, the redemption fee will be charged in generally the same manner as for shares held directly with the Fund. However, the intermediaries' methods for tracking and calculating the fee may differ in some respects from the Fund's.

ANNUAL FUND OPERATING EXPENSES (DEDUCTED DIRECTLY FROM FUND ASSETS)

Management fee(1) (%)                                         0.85
------------------------------------------------------------------
Distribution and service (12b-1) fees (%)                     0.00
------------------------------------------------------------------
Other expenses(2) (%)                                         0.23
------------------------------------------------------------------
Total annual fund operating expenses(1)(2) (%)                1.08

(1) Management fees have been restated to reflect contractual changes to the management fee of the Fund effective November 1, 2004.

(2) The Fund's transfer agent has voluntarily agreed to waive up to 0.10% of the Fund's transfer agency fee. Currently, it is expected that the waiver will be 0.08%. If this waiver is reflected in the table, the Other Expenses for Class Z shares would be 0.15%, and the total annual fund operating expenses would be 1.00%.

EXAMPLE EXPENSES (YOUR ACTUAL COSTS MAY BE HIGHER OR LOWER)

1 YEAR   3 YEARS   5 YEARS   10 YEARS
 $110     $343      $595      $1,317

See Appendix A for additional hypothetical investment and expense information.

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

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, D 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 investment 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 "Your Account -- 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 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 "Fund Policy on Trading of Fund Shares" below as well as 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, the Fund will generally 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.

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 generally 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 the 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

The 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 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 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.

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


14

YOUR ACCOUNT

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 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 (typically Monday through Friday). Shares are not priced on 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 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.

YOUR ACCOUNT

You can find the daily prices of some share classes for the Fund in most major daily newspapers under the caption "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, generally based on the number of shares you own at the time these distributions are declared.

DISTRIBUTION OPTIONS The Fund declares and pays dividends at least 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, or if you do not cash a distribution check within six months of the check date, the distribution will be reinvested in additional shares of the Fund. All subsequent distributions will be reinvested.


16

YOUR ACCOUNT

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 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 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 0.85% of average daily net assets of 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


18

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 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.

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 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 and that all dividends and distributions are reinvested. The annual expense ratio used for the Fund, which is the same as that is stated in the Annual Fund Operating Expenses tables, is reflected in the chart and is net of any fee waiver or expense reimbursement.

ORGANIZATION AND HISTORY

The Trust is a Massachusetts business trust organized in 1987. The Fund is an open-end management diversified investment company, representing the entire interest in a separate series of the Trust. The Fund is expected to commence investment operations as a series of the Trust on October 10, 2005. Prior to October 10, 2005 (the "Fund Reorganization Date"), the Fund was organized as an Oregon corporation (the "Predecessor Fund") that commenced investment operations in 1992. The information provided for the fund in this SAI for periods prior to the Fund Reorganization Date relates to the Predecessor Fund.

The Fund offers six classes of shares - Classes A, B, C, D, G and Z shares.

The Trust 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 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 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:

Debt Securities (other than Lower-Rated Debt Securities and Municipal Securities)
Government Obligations (U.S. Government obligations only) Bank Obligations (Domestic only)
Options on Securities
Future Contracts and Related Options
Foreign Currency Transactions
Foreign Securities
Repurchase Agreements
Forward Commitments
Convertible Securities
Small Companies
REITS

Except as indicated below under "Fundamental and Non-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 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 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.

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 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 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; and

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 Act, the rules and regulations thereunder, or any applicable exemptive relief.

OTHER INVESTMENT POLICIES

The following non-fundamental investment policies may be changed without shareholder approval:

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, as defined in Part II of this Statement of Additional Information, provided, however, that it may invest in Rule 144A Securities under the supervision of the Board of Trustees as described in Part II of this Statement of Additional Information;

(2) enter into Foreign Currency Transactions except

a. for the purpose of hedging transactions, and in any case not to the extent of more than 25% of the net assets of the Fund or

b. in the case of spot (or cash) transactions in connection with the settlement of transactions in portfolio securities;

(3) purchase or otherwise acquire any securities if, as a result, more than 5% of its total assets would be invested in securities issued by unseasoned companies, generally those with less than three years operating history;

c

(4) borrow money in excess of 33.3% of its net 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." 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 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 Fund to realize capital gains which, if realized and distributed by the Fund, may be taxable to shareholders as ordinary income. High portfolio turnover in the Fund's portfolio may result in correspondingly greater brokerage commissions and other transaction costs, which would be borne directly by the Fund.

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, determined at the close of each business day during the month, as follows:

0.870% of the Fund's first $500 million of net assets; 0.820% of next $500 million of net assets; 0.770% of next $500 million of net assets; 0.720% of next $1.5 billion of net assets; 0.700% of next $3 billion of net assets; and 0.680% of net assets in excess of $6 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:

1.000% of the Fund's first $500 million of net assets; 0.950% of the next $500 million of net assets; and 0.900% of net assets in excess of $1 billion.
Additionally, the Advisor had voluntarily agreed to waive a portion of its investment advisory fee for the Fund at an annual rate of 0.10% of the average daily net assets for the period September 1, 2004 through October 31, 2004. The annualized effective rate of this waiver is 0.01%.

Under its pricing, bookkeeping and fund administration agreement with the Fund, the Advisor receives from the Fund a monthly fee consisting of:

- a minimum of $25,000 plus two basis points for fund accounting and

- $19,965 for financial reporting

The maximum combined fee payable is $150,000.

The Advisor will also be compensated for certain out-of-pocket expenses

The Fund pays to CMS a shareholders' servicing and transfer agency fee consisting of 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.

OWNERSHIP OF SECURITIES

The table below shows the dollar ranges of shares of the Fund beneficially owned (as determined pursuant to Rule 16a-1(a)(2) under the Securities Exchange Act of 1934, as amended) by the portfolio managers listed above at the end of the Fund's most recent fiscal year:

Deborah F. Snee                               $     1 - $10,000

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.

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 PLANS, CDSC AND CONVERSION OF SHARES

The Fund offers six classes of shares - Class A, Class B, Class C, Class D, Class G and Class Z. The Fund may in the future offer other classes of shares. The Trustees of the Trust have approved a 12b-1 Plan (Plan) pursuant to Rule 12b-1 under the Act except Class Z shares. 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, Class C, Class D and Class G shares. The Fund pays a distribution fee at the annual rate of 0.75% of the average daily net assets attributed to its Class B, Class C, Class D shares. The Fund pays a distribution fee at the annual rate of 0.65% of the average daily net assets attributed to its Class G shares. The Fund's Board of Directors currently limits payments under the 12b-1 Plan for Class A shares to 0.25% annually. CMD may use the entire amount of such fees to

k


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 indirect financing of the distribution of the Fund 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 are 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 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 the program you purchased your shares under. 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 Prospectus for the Fund's Class A, Class B, Class C and Class G 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 or G 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.

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

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 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

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.

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.

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.

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;

12

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 clearing corporation may not at all times be adequate to handle current trading volume; or (vi) one or more exchanges could, for

13

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

14

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

15

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.

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.

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

18

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. 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

19

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. Treasury securities maturing on a quarterly basis through the conversion date, and a forward purchase contract with an existing

20

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, 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

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, 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.

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.

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.

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.

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 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).

36

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.

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

39

"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.

40

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 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 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

41

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.

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.

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.

43

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 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 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.

47

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.

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.

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:

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.

50

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.

51

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, 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.

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 schedul e 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:

54

                                % 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.

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.

56

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 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).

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.

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:

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.

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, 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.

63

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.

64

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);

65

(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.

66

- 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.

67

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.

68

- 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.

69

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.

- 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.

THE FUND

INVESTMENT GOALS

The Fund seeks long-term capital growth while reducing shareholder exposure to taxes.

PRINCIPAL INVESTMENT STRATEGIES

The Fund invests primarily in large capitalization (large-cap) and middle capitalization (mid-cap) stocks. Large-cap stocks are stocks of large-size companies that have market capitalizations similar in size to those companies in the S&P 500 Index. As of December 31, 2004, that index included companies with capitalizations between $749 million and $386 billion. Mid-cap stocks are stocks of mid-size companies that have market capitalizations similar in size to those companies in the Russell Mid Cap Growth Index. As of December 31, 2004, that index included companies with capitalizations between $631 million and $25 billion. All market capitalizations are determined at the time of purchase. The Fund may also invest in foreign securities. In selecting stocks for the Fund, the Fund's investment sub-advisor uses fundamental research analysis and valuation techniques.

UNDERSTANDING TAX-MANAGED INVESTING

In managing the Fund, the sub-advisor uses investment strategies that are designed to reduce (but not eliminate) the payment by the Fund of taxable distributions to shareholders. These strategies include: buying stocks that pay low dividends or no dividends at all; maintaining a low portfolio turnover rate which helps to minimize the realization and distribution of taxable gains; deferring the sale of a security until the realized gain would qualify as a long-term capital gain rather than a short-term capital gain; selling securities to create a loss to offset gains realized on other securities; and selling the higher cost basis portion of a security holding before the lower cost basis portion.

From time to time, the Fund expects to distribute taxable income and capital gains. Market conditions may limit the Fund's ability to generate tax losses or to avoid dividend income. Additionally, the ability to use certain tax management techniques may be curtailed or eliminated in the future by tax legislation or regulation.

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.

At times, the sub-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.

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 sub-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.

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 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.

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, E and F 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. All information in this prospectus relating to the Fund for periods prior to October 10, 2005, including the performance information shown below, is that of Columbia Tax-Managed Growth Fund, a series of Columbia Funds Trust I, 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.


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 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. 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

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.

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

- Class F shares convert to Class E 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. For purchases of trust shares, a signed Trust Declaration Agreement must be received within ten days following the purchase. 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 traditional 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.

The Fund offers two trust classes of shares in this prospectus -- CLASS E and F. These classes are designed for persons who wish to make an irrevocable gift to a child, grandchild or other individual. Shares are held in an irrevocable trust until a specified date, at which time they pass to a beneficiary. Each share class has its own sales charge and expense structure. Determining which share class is best for you depends on the length of time between the purchase date and the designated trust termination date. Purchases of $250,000 or more can be made only in Class E 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.

TRADITIONAL SHARES

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:

YOUR ACCOUNT


UNDERSTANDING CONTINGENT DEFERRED SALES CHARGES

Certain investments in Class A, B, C, E and F 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


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 advisors 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.

TRUST SHARES

Trust shares may be purchased by individuals seeking a convenient way to give an investment in the Fund to a child, grandchild or other individual. Rather than being held directly by you or the gift's eventual recipient (beneficiary), trust shares are held in an irrevocable trust, the trustee of which is an officer of the administrator, until the trust termination date you specify, at which time the shares pass to the beneficiary. Distributions from the trust are permitted only for limited specified purposes. Subsequent investments into the same account do not affect the original trust termination date; however, no additional investments into an account (other than reinvestment of distributions) may be made within two years of the termination date. The duration of the trust may be as long as you choose, but must be at least 5 years from the initial purchase into the trust or until the beneficiary reaches the age of 18, whichever is later. The trust will terminate, and the amounts held in the trust will be distributed, in the event of the beneficiary's death prior to the original trust termination date.

Two types of trust plans are available: Columbia Gift Plan and Columbia Advantage Plan. Each plan has different provisions for the payment of distributions prior to trust termination and different tax implications for the donor and/or beneficiary. The plan that is most suitable for you will depend on your specific financial and tax circumstances and your gift-giving objectives. The distributor provides the Fund with trust administration services with respect to each trust share class for which the Fund pays an annual fee equal to approximately $25-$50 for each open trust share account.


13

YOUR ACCOUNT

EACH PLAN IS DESCRIBED BELOW:

COLUMBIA GIFT PLAN

The Columbia Gift Plan is designed to serve exclusively as a vehicle for making a future gift of the Fund's shares. Under the Columbia Gift Plan, the beneficiary will have no ability to access or withdraw the shares until the trust's termination. Because the gift is viewed by the Internal Revenue Service as a gift of a future interest, the gift will not be eligible for the federal annual gift tax exclusion. The trust, not the beneficiary, will be taxed on any income and capital gains earned by the trust in excess of $100 per year.

The trustee will prepare and file all federal and state income tax returns that are required each year and will satisfy any taxes owed from the assets of the trust by redeeming Fund shares.

COLUMBIA ADVANTAGE PLAN

The Columbia Advantage Plan is designed to permit the donor and, under certain circumstances, the beneficiary, to direct the trustee to make distributions from the trust for specified purposes, and to provide additional benefits to the donor. Under the Columbia Advantage Plan, during the first 30 days following the contribution the beneficiary will have the right to withdraw the shares purchased by such contribution at their net asset value, plus any sales charge paid on the purchase, and the contribution will be eligible for the annual federal gift tax exclusion. The trustee will provide the beneficiary with notice of the withdrawal right at the time of each contribution. The beneficiary will be taxed on all of the trust's income and capital gains. In connection with the initial contribution, the donor may direct the trustee, or authorize the beneficiary (if he or she is over 18) or the beneficiary's representative (if he or she is not also the donor) to direct the trustee, to redeem Fund shares and distribute the proceeds to the beneficiary in order to provide funds for the beneficiary to pay such taxes. Such distributions would be made within 90 days after the end of each calendar year. The amount of each distribution would be determined by multiplying the amount of each class of income earned by the trust during the year times the highest marginal federal tax rate for unmarried individuals applicable to that class of income. Once made, the election to receive tax distributions may not be revoked.

In connection with the initial contribution, the donor also may authorize the beneficiary (if he or she is over 18), or the beneficiary's representative (if he or she is not also the donor), to direct the trustee to redeem shares and pay the proceeds directly to a recognized post-secondary educational institution to cover the beneficiary's post-secondary educational expenses. Once made, the election to allow such distributions may not be revoked.

No other distributions from the trust are permitted until the trust's termination date. The trustee will send an information statement to the beneficiary each year showing the amount of income and capital gains to be reported on his or her income tax returns for that year.

The foregoing is only a general summary of the tax implications of an investment in the Fund's trust shares. More detailed information is available in the Statement of Additional Information. You should consult your financial or tax advisor for specific advice concerning which option may be most suitable for you.

Under each Plan, upon termination of the trust, the underlying trust shares (matured trust shares) automatically pass to the beneficiary. Prior to the termination date, a notice will be sent to the beneficiary notifying him or her of the impending termination date and the options available to the beneficiary, and requesting certain information, including the beneficiary's social security number. The beneficiary may be asked to sign and return a Form W-9. If not redeemed at this time by the beneficiary, Class E shares and Class F shares


14

YOUR ACCOUNT

automatically will convert to Class A shares and Class B shares, respectively, and be registered in the beneficiary's name. If the beneficiary dies during the term of the trust, the shares automatically pass to the beneficiary's executors or administrators to be disposed of as part of the beneficiary's estate.

CLASSES OF TRUST SHARES

CLASS E SHARES Your purchases of Class E 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. A portion of the sales charge is paid as a commission to your financial advisor on the sale of Class E shares. The amount of the sales charge differs depending on the amount you invest as shown in the table below.

If, at the time of the trust's termination, the beneficiary does not elect to redeem Class E shares held by the trust, the shares automatically will convert to Class A shares of the Fund and be registered in the beneficiary's name.

Class F 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. Class F shares automatically convert to Class E shares after eight years. The distributor pays your financial advisor an up-front commission of 4.00% on sales of Class F shares.

If, at the time of the trust's termination, the beneficiary does not elect to redeem Class F shares held by the trust, the shares automatically will convert to Class B shares of the Fund and be registered in the beneficiary's name.

WITHDRAWAL UNDER THE COLUMBIA ADVANTAGE PLAN. If the beneficiary under a Columbia Advantage Plan trust exercises his or her withdrawal rights, the financial advisor shall refund to the distributor any sales charge or initial commission previously retained or paid on the withdrawn shares or amount redeemed.

HOW TO EXCHANGE SHARES

Trust shares may not be exchanged for shares of any other fund distributed by Columbia Management Distributors, Inc. You may exchange your Class A, B and C shares for shares of the same share class (and in some cases, certain other classes) of another fund distributed by Columbia Management 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.

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 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.

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.


18

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, E and F 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, Class E and Class F shares. The annual distribution fee may equal up to 0.75% for each of Class B, Class C and Class F shares and 0.10% for Class E 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. Class F shares automatically convert to Class E 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 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 trust shares are automatically reinvested until the trust's termination unless used to fund trust distributions permitted under the Columbia Advantage Plan.

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


21

YOUR ACCOUNT

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. Under the Columbia Gift Plan, the trustee will file all income tax returns and pay all income taxes for income earned prior to the trust's termination. Under the Columbia Advantage Plan, the beneficiary will be obligated to report any income earned by the trust on his or her tax returns and to pay any applicable income 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.

A gift made through the purchase of the Fund's trust shares may have to be reported under federal gift tax laws and may be subject to federal gift taxes. In general, a federal gift tax return must be filed reporting all gifts made by an individual during any calendar year, unless the gift qualifies for the annual federal gift tax exclusion. To so qualify, the gift must be a gift of a "present interest" and must not exceed $11,000 when combined with any other gifts made to the same beneficiary during the calendar year. The limit is $22,000 for a married couple who elect "gift splitting," but such election must be made on a gift tax return filed for the calendar year in which the gift is made. Whether a gift made through the purchase of the Fund's trust shares qualifies for the annual exclusion depends on the plan selected by the donor as well as on the combined amount of the gift and any other gifts made to the beneficiary by the donor during the particular year. In general, if no other gifts are made during the year to the beneficiary, a gift under the Columbia Advantage Plan will qualify for the federal gift tax exclusion to the extent it does not exceed the $11,000/$22,000 maximum. A gift under the Columbia Gift Plan will not qualify for the annual exclusion. A gift tax return reporting the amount of the gift under the Columbia Gift Plan and the amount of any gift under the Columbia Advantage Plan not qualifying for the annual exclusion must be filed by the donor. A gift tax return must also be filed by a married donor to elect gift splitting and thereby take advantage of the higher $22,000 limitation on the annual exclusion. Any gift tax due on account of the purchase of trust shares is the sole responsibility of the donor and will not be paid from the trust shares.

A purchase of trust shares may also be subject to state gift tax reporting requirements under the laws of the state in which the donor of the gift resides. See "Trust Shares" above and "Additional Tax Matters Concerning Trust Shares" in the Fund's Statement of Additional Information for more detailed information about these and other tax matters applicable to an investment in the Fund. Due to the complexity of federal and state laws pertaining to gifts in trust, you should consult your financial or tax advisor before investing in the Fund's trust shares.

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.

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'

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 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.

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 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 is stated in the Annual Fund Operating Expenses tables, is reflected in the chart and is net of any fee waiver or expense reimbursement.

THE FUND

INVESTMENT GOALS

The Fund seeks long-term capital growth while reducing shareholder exposure to taxes.

PRINCIPAL INVESTMENT STRATEGIES

The Fund invests primarily in large capitalization (large-cap) and middle capitalization (mid-cap) stocks. Large-cap stocks are stocks of large-size companies that have market capitalizations similar in size to those companies in the S&P 500 Index. As of December 31, 2004, that index included companies with capitalizations between $749 million and $386 billion. Mid-cap stocks are stocks of mid-size companies that have market capitalizations similar in size to those companies in the Russell Mid Cap Growth Index. As of December 31, 2004, that index included companies with capitalizations between $631 million and $25 billion. All market capitalizations are determined at the time of purchase. The Fund may also invest in foreign securities. In selecting stocks for the Fund, the Fund's investment sub-advisor uses fundamental research analysis and valuation techniques.

UNDERSTANDING TAX-MANAGED INVESTING

In managing the Fund, the sub-advisor uses investment strategies that are designed to reduce (but not eliminate) the payment by the Fund of taxable distributions to shareholders. These strategies include: buying stocks that pay low dividends or no dividends at all; maintaining a low portfolio turnover rate which helps to minimize the realization and distribution of taxable gains; deferring the sale of a security until the realized gain would qualify as a long-term capital gain rather than a short-term capital gain; selling securities to create a loss to offset gains realized on other securities; and selling the higher cost basis portion of a security holding before the lower cost basis portion.

From time to time, the Fund expects to distribute taxable income and capital gains. Market conditions may limit the Fund's ability to generate tax losses or to avoid dividend income. Additionally, the ability to use certain tax management techniques may be curtailed or eliminated in the future by tax legislation or regulation.

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.

At times, the sub-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.

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 goals. You may lose money by investing in the Fund.

Management risk means that the sub-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.

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 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.

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 for the life of the Fund. All information in this prospectus relating to the Fund for periods prior to October 10, 2005, including the performance information shown below, is that of Columbia Tax-Managed Growth Fund, a series of Columbia Funds Trust I, 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.


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 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. 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.

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, 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. For purchases of trust shares, a signed Trust Declaration Agreement must be received within ten days following the purchase. 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 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 offers two trust classes of shares, CLASS E and F shares, which are made available through a separate prospectus. These classes are designed for persons who wish to make an irrevocable gift to a child, grandchild or other individual. Shares are held in an irrevocable trust until a specified date, at which time they pass to a beneficiary. Each share class has its own sales charge and expense structure. Determining which share class is best for you depends on the length of time between the purchase date and the designated trust termination date. Purchases of $250,000 or more can be made only in Class E shares.

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.

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:

YOUR ACCOUNT


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


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 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.

HOW TO EXCHANGE SHARES


You may exchange your Class A, B and C 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.

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 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.


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 0.75% 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. Class F shares automatically convert to Class E shares after eight years, eliminating a portion of 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 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,


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 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 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 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'


21

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 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.

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 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 is stated in the Annual Fund Operating Expenses tables, is reflected in the chart and is net of any fee waiver or expense reimbursement.

THE FUND

INVESTMENT GOALS

The Fund seeks long-term capital growth while reducing shareholder exposure to taxes.

PRINCIPAL INVESTMENT STRATEGIES

The Fund invests primarily in large capitalization (large-cap) and middle capitalization (mid-cap) stocks. Large-cap stocks are stocks of large-size companies that have market capitalizations similar in size to those companies in the S&P 500 Index. As of December 31, 2004, that index included companies with capitalizations between $749 million and $386 billion. Mid-cap stocks are stocks of mid-size companies that have market capitalizations similar in size to those companies in the Russell Mid Cap Growth Index. As of December 31, 2004, that index included companies with capitalizations between $631 million and $25 billion. All market capitalizations are determined at the time of purchase. The Fund may also invest in foreign securities. In selecting stocks for the Fund, the Fund's investment sub-advisor uses fundamental research analysis and valuation techniques.

UNDERSTANDING TAX-MANAGED INVESTING

In managing the Fund, the sub-advisor uses investment strategies that are designed to reduce (but not eliminate) the payment by the Fund of taxable distributions to shareholders. These strategies include: buying stocks that pay low dividends or no dividends at all; maintaining a low portfolio turnover rate which helps to minimize the realization and distribution of taxable gains; deferring the sale of a security until the realized gain would qualify as a long-term capital gain rather than a short-term capital gain; selling securities to create a loss to offset gains realized on other securities; and selling the higher cost basis portion of a security holding before the lower cost basis portion.

From time to time, the Fund expects to distribute taxable income and capital gains. Market conditions may limit the Fund's ability to generate tax losses or to avoid dividend income. Additionally, the ability to use certain tax management techniques may be curtailed or eliminated in the future by tax legislation or regulation.

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.

At times, the sub-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.

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 goals. You may lose money by investing in the Fund.

Management risk means that the sub-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.

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 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.

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 for the life of the Fund. All information in this prospectus relating to the Fund for periods prior to October 10, 2005, including the performance information shown below, is that of Columbia Tax-Managed Growth Fund, a series of Columbia Funds Trust I, 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.


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 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. 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 Class A shares (the oldest existing 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 December 30, 1996, and Class Z shares were initially offered on January 11, 1999.

(2) Performance information is from December 30, 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

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 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

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 Funds 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. (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 Columbia Funds Distributor, Inc.;

- Any trustee or director (or family member of a trustee or director) of any fund distributed by CMD;


8

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 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); or

- Any institutional investor which is a corporation, partnership, trust, foundation, endowment, 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 their 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, E and F 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. Class E and F shares are designed for persons who wish to make an irrevocable gift to a child, grandchild or other individual. Shares are held in an irrevocable trust until a specified date, at which time they pass to a beneficiary. 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

YOUR ACCOUNT

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 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.


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 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.

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 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 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 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.

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 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 Fund, which is the same as that is stated in the Annual Fund Operating Expenses tables, is reflected in the chart and is net of any fee waiver or expense reimbursement.

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.

As fundamental investment policies, each Fund may:

1. Borrow from banks, other affiliated funds and other entities to the extent permitted by applicable law, 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. Only own real estate acquired as a result of owning securities and not more than 5% of total assets;

3. Not invest in commodities, except that the Fund may purchase and sell futures contracts and related options to the extent that total initial margin and premiums on the contracts do not exceed 5% of its total assets;

b


4. Not issue senior securities except as provided in paragraph 1 above and to the extent permitted by the 1940 Act;

5. Underwrite securities issued by others only when disposing of portfolio securities;

6. Make loans (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 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) and (d) through repurchase agreements; and

7. Not concentrate more than 25% of its total assets in any one industry or with respect to 75% of total assets purchase any security (other than obligations of the U.S. government and cash items including receivables) if as a result more than 5% of its total assets would then be invested in securities of a single issuer, or purchase voting securities of an issuer if, as a result of such purchases, the Fund would own more than 10% of the outstanding voting shares of such issuer.

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 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; and

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 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.

Notwithstanding the investment policies and restrictions of the Fund, the 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.

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." 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 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 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. The Fund seeks to maintain a low portfolio turnover rate, although the Fund may engage in higher portfolio turnover in order to reduce shareholder exposure to taxes (such as when the Advisor sells securities to create a loss to offset gains realized on other securities).

FUND CHARGES AND EXPENSES

Under the Fund's management agreement, the Fund pays the Advisor a monthly fee at the annual rate of:

Average Daily Net Assets                                               Rate
------------------------                                               ----
Net assets under $500 million                                          0.520%
Net assets of $500 million but less than $1 billion                    0.470%
Net assets of $1 billion but less than $1.5 billion                    0.420%
Net assets of $1.5 billion but less than $3 billion                    0.370%
Net assets of $3 billion but less than $6 billion                      0.350%
Net assets in excess of $6 billion                                     0.330%

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 the Fund's management agreement, the Fund paid the Advisor a monthly fee at the annual rate of 0.60% on the first $500 million of the average daily net assets of the Fund, 0.55% on the next $500 million and 0.50% of any excess over $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 0.60%.

d

Under the sub-advisory agreement for the Fund, the Advisor pays the Sub-Advisor a monthly base fee at the annual rate of 0.20% of the average daily net assets of the Fund (Base Fee), which may be adjusted to an annual rate as high as 0.25% or an annual rate as low as 0.15% depending on the Fund's performance. The total monthly fee payable to the Sub-Advisor is determined by multiplying the Base Fee by a performance adjustment rate (Performance Adjustment Rate), which is readjusted quarterly depending on the Fund's performance over a specified period of time as measured by Morningstar, Inc.'s Large Blend category for domestic equity funds. The Performance Adjustment Rates applicable to each Morningstar ranking are as follows:

                                   Performance
Morningstar Ranking                Adjustment Rate
-------------------                ---------------
Quartile 1                              1.25
Quartile 2                              1.00
Below Median                            0.75

The sub-advisory agreement also provides that the Sub-Advisor shall not receive a fee less than $350,000 per annum in the aggregate for managing the Fund. The Advisor pays the sub-advisory fees to the Sub-Advisor under the sub-advisory agreements. The Fund does not pay any fees to the Sub-Advisor.

Under the Fund's administration agreement, the Fund pays the Administrator a monthly fee at the annual rate of 0.25% of the average daily net assets of the Fund.

The Advisor is responsible for providing pricing and bookkeeping services to the Fund pursuant to a pricing and bookkeeping agreement. Under a separate agreement (the "Outsourcing Agreement"), the Advisor has delegated those functions to State Street Corporation ("State Street"). The Advisor pays fees to Sate 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.

Prior to November 1, 2003, 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.

INVESTMENT OVERSIGHT COMMITTEES

Beginning in 2004, each Trustee of the Funds also began serving on an Investment Oversight Committee ("IOC"). Each IOC is responsible for monitoring, on an ongoing basis, a select group of funds in the fund complex and gives particular consideration to such matters as the Funds' adherence to their investment mandates, historical performance, changes in investment processes and personnel, and proposed changes to investment objectives. Investment personnel who manage the Fund attend IOC meetings

h


from time to time to assist each IOC in its review of the Fund. Each IOC meets four times a year. The following are members of the respective IOCs and the general categories of funds in the Fund Complex which they review:

IOC #1:     Messrs. Lowry, Mayer and Neuhauser are responsible for
            reviewing funds in the following asset categories: Large
            Growth Diversified, Large Growth Concentrated, Small
            Growth, Outside Managed (i.e., sub-advised) and

COMPENSATION

Each portfolio manager's compensation consists of the following five elements:

BASE SALARY Each portfolio manager is paid a base salary which is set at a level determined to be appropriate based upon an individual's experience and responsibilities through the use of an independent compensation survey of the investment management industry.

ANNUAL BONUS Each portfolio manager is paid an annual cash bonus, which is discretionary and based on a number of factors. Such factors may include:

o the success and consistency of the team's investment results, as measured against appropriate market benchmarks and peer groups;

o generation and contribution of investment ideas;

o contributions to asset retention, gathering and client satisfaction;

o contributions to mentoring, coaching and/or supervising; and

o overall contribution to the firm.

EQUITY-BASED COMPENSATION Portfolio managers may be awarded options to purchase common shares and/or granted restricted shares or deferred shares of AMVESCAP stock from pools determined from time to time by the Remuneration Committee of the AMVESCAP Board of Directors. Awards of equity-based compensation typically vest over time, so as to create incentives to retain key talent.

PARTICIPATION IN GROUP INSURANCE PROGRAMS Portfolio managers are provided life insurance coverage in the form of a group variable universal life insurance policy, under which they may make additional contributions to purchase additional insurance coverage or for investment purposes.

PARTICIPATION IN DEFERRED COMPENSATION PLAN Portfolio managers are eligible to participate in a non-qualified deferred compensation plan, which affords participating employees the tax benefits of deferring the receipt of a portion of their cash compensation.

INVESTMENT ADVISOR

Under the management agreement with the Fund, the Advisor provides the Fund with discretionary investment services. Specifically, the Advisor is responsible for supervising and directing the investments of the Fund in accordance with the Fund's investment goals, programs, and restrictions as provided in the Fund's Prospectuses and this SAI. The Advisor is also responsible for effecting all security transactions on behalf of the Fund, including the allocation of principal business and portfolio brokerage and the negotiation of commissions (see "Portfolio Transactions" below). The Management Agreement provides for the payment to the Advisor of the fee described in the Prospectuses.

Under the Management Agreement, the Advisor is not 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 such Agreements relate, except a loss resulting from willful misfeasance, bad faith or gross negligence in the performance of its duties or from reckless disregard of its obligations and duties under the Agreement.

PORTFOLIO TRANSACTIONS

The Sub-Advisor places the orders for the purchase and sale of the Fund's portfolio securities and options and futures contracts. The Sub-Advisor's overriding goals in effecting portfolio transactions is to seek to obtain the best combination of price and execution. The best net price, giving effect to brokerage commissions, if any, and other transaction costs, normally is an important factor in this decision, but a number of other criteria may also enter into the decision. These include: the Sub-Advisor's knowledge of negotiated commission rates currently available and other current transaction costs; the nature of the security being traded; the size of the transaction; the desired timing of the trade; the activity existing and expected in the market for the particular security; confidentiality; the execution, clearance and settlement capabilities of the broker or dealer selected and others which are considered; the Sub-Advisor's knowledge of the financial stability of the broker or dealer selected and such other brokers or dealers; and the Sub-Advisor's knowledge of actual or apparent operational problems of any broker or dealer. Recognizing the value of these factors, the Fund may pay a brokerage commission in excess of that which another broker or dealer may have charged for effecting the same transaction. Evaluations of the reasonableness of brokerage commissions, based on the foregoing factors, are made on an ongoing basis by the Sub-Advisor's staff while effecting portfolio transactions. The general level of brokerage commissions paid is reviewed by the Advisor and Sub-Advisor, and reports are made annually to the Board of Trustees of the Fund.

With respect to issues of securities involving brokerage commissions, when more than one broker or dealer is believed to be capable of providing the best combination of price and execution with respect to a particular portfolio transaction for the Fund, the Sub-Advisor often selects a broker or dealer that has furnished it with research products or services such as research reports, subscriptions to financial publications and research compilations, compilations of securities prices, earnings, dividends, and similar data, and computer data bases, quotation equipment and services, research-oriented computer software and services, and services of economic and other consultants. Selection of brokers or dealers is not made pursuant to an agreement or understanding with any of the brokers or dealers; however, the Sub-Advisor uses an internal allocation procedure to identify those brokers or dealers who provide it with research products or services and the amount of research products or services they provide, and endeavors to direct sufficient commissions generated by its clients' accounts in the aggregate, including the Fund, to such brokers or dealers to ensure the continued receipt of research products or services that the Sub-Advisor feels are useful. In certain instances, the Sub-Advisor receives from brokers and dealers products or services which are used both as investment research and for administrative, marketing, or other non-research purposes. In such instances, the Sub-Advisor makes a good faith effort to determine the relative proportions of such products or services which may be considered as investment research.

m

The portion of the costs of such products or services attributable to research usage may be defrayed by the Sub-Advisor (without prior agreement or understanding, as noted above) through transaction charges generated by transactions by clients (including the Fund), while the portions of the costs attributable to non-research usage of such products or services is paid by the Sub-Advisor in cash. No person acting on behalf of the Fund is authorized, in recognition of the value of research products or services, to pay a commission in excess of that which another broker or dealer might have charged for effecting the same transaction. Research products or services furnished by brokers and dealers may be used in servicing any or all of the clients of the Sub-Advisor and not all such research products or services are used in connection with the management of the Fund.

With respect to the Fund's purchases and sales of portfolio securities transacted with a broker or dealer on a net basis, the Sub-Advisor may also consider the part, if any, played by the broker or dealer in bringing the security involved to the Sub-Advisor's attention, including investment research related to the security and provided to the Fund. The Fund has arranged for its custodian to act as a soliciting dealer to accept any fees available to the custodian as a soliciting dealer in connection with any tender offer for the Fund's portfolio securities. The custodian will credit any such fees received against its custodial fees. In addition, the Board of Trustees has reviewed the legal developments pertaining to and the practicability of attempting to recapture underwriting discounts or selling concessions when portfolio securities are purchased in underwritten offerings. However, the Board has been advised by counsel that recapture by a mutual fund currently is not permitted under the Rules of Fair Practice of the National Association of Securities Dealers.

The Sub-Advisor may use the services of an affiliate of the Advisor, when buying or selling securities for the Fund's portfolio pursuant to procedures adopted by the Trustees and 1940 Act Rule 17e-1. Under the Rule, the Sub-Advisor must ensure that commissions the 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 Sub-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.

12B-1 PLAN, CDSCS AND CONVERSION OF SHARES

The Fund offers six classes of shares - Class A, Class B, Class C, Class E, Class F 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 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, Class C, Class E and Class F shares. The Fund also pays CMD monthly a distribution fee at an annual rate of 0.10% of the average daily net assets attributed to Class E 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 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 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 E shares are offered at net asset value plus varying sales charges which may include a CDSC. Class F shares are offered at net asset value and are subject to a CDSC if redeemed within six

n


years. 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 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 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, 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

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 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

3

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

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.

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.

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.

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;

12

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 clearing corporation may not at all times be adequate to handle current trading volume; or (vi) one or more exchanges could, for

13

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

14

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

15

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.

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.

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

18

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. 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

19

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. Treasury securities maturing on a quarterly basis through the conversion date, and a forward purchase contract with an existing

20

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, 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

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, 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.

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.

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.

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.

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 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).

36

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.

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

39

"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.

40

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 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 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

41

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.

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.

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.

43

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.

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 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.

47

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.

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.

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:

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.

50

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.

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.

51

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, 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.

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.

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.

56

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 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).

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.

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:

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.

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.

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.

63

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.

64

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);

65

(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.

66

- 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.

67

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.

68

- 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.

69

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.

- 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.

THE FUND

INVESTMENT GOALS

The Fund seeks as high a level of current income and total return as is consistent with prudent risk.

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. government securities, including U.S. treasuries and securities of various U.S. government agencies and instrumentalities. Agency securities include mortgage-backed securities, which represent interests in pools of mortgages. Certain securities of U.S. government agencies and instrumentalities in which the Fund invests are neither issued nor guaranteed by the U.S. Treasury. 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.

The Fund may also invest up to 20% of its assets in corporate bonds or mortgage- or asset-backed securities that are issued by private entities. These securities must be rated investment grade by Moody's Investors Service, Inc., Standard & Poor's or Fitch, Inc.

The Fund has wide flexibility to vary its allocation among different types of U.S. government securities and the securities of non-governmental issuers based on the Fund's investment advisor's judgment of which types of securities will outperform the others. In selecting investments for the Fund, the advisor considers a security's expected income together with its potential to rise or fall in price.

The Fund generally maintains a duration of greater than three years and less than ten years. As a result, the Fund's portfolio has market risks and an expected average life comparable to intermediate- to long-term bonds. The advisor may vary the Fund's duration depending on its forecast of interest rates and market conditions. For example, when interest rates are expected to increase, the advisor may shorten the duration, and vice versa.


UNDERSTANDING DURATION

DURATION is the most common measure of the interest rate risk of a bond. It measures the sensitivity of the bond's price to changes in interest rates. A fund's duration is the average of the durations of the securities in which the fund invests. Generally, the shorter a fund's duration, the less its share price will change when there is a change in interest rates.

The advisor uses duration management to control some of the potential risk of investing in the Fund.

THE FUND

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, 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.

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. All information in this prospectus relating to the Fund for periods prior to September 26, 2005, including the performance information shown below, is that of Columbia Federal Securities Fund, a series of Columbia Funds Trust III, 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 "Your Account -- Sales Charges" below).

The Fund's returns are compared to the Citigroup Government/Mortgage Index (Citigroup Index), an unmanaged index that is a combination of the Citigroup U.S. Government Index (Government Index) and the Citigroup Mortgage Index (Mortgage Index). The Government Index tracks the performance of the Treasury and Government-Sponsored Indices within the U.S. Broad Investment Grade Bond Index. The Mortgage Index tracks the performance of the mortgage component of the U.S. BIG Bond Index, comprising 30- and 15-year GNMA, FNMA and FHLMC pass-throughs and FNMA and FHLMC balloon mortgages. 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 U.S. Government 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.

through June 30, 2005 was 2.61%.              Worst quarter: 1st quarter 1996, -3.68%

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, 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

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 1.67%. 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.

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:

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 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


11

YOUR ACCOUNT

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.

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

YOUR ACCOUNT

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 that are deemed material by the Fund in any 28-day period, the Fund will generally reject the


14

YOUR ACCOUNT

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, it 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 generally 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 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 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.


16

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. 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 not 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 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


17

YOUR ACCOUNT

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 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

Effective September 30, 2005, Columbia Management Advisors, LLC ("Columbia Advisors"), located at 100 Federal Street, Boston, Massachusetts 02110, will become the Fund's investment advisor. Columbia Advisors will be responsible for the Fund's management, subject to oversight by the Fund's Board of Trustees. In its duties as investment advisor, Columbia Advisors will run 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"), an affiliate of Columbia Advisors with offices at the same location, will merge into Columbia Advisors. Columbia Management will be the investment advisor to the Fund until September 30, 2005. As a result of the merger, Columbia Advisors will become 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 0.60% of average daily net assets of the Fund.

PORTFOLIO MANAGER

ANN T. PETERSON, a senior vice president of Columbia Management, is the manager for the Fund and managed or co-managed the Fund since June, 2000. Since 1993, she has served as a manager or co-manager of various other taxable income funds for Columbia Management or its predecessors.

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


19

MANAGING THE FUND

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.

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.

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.

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.

SHORT SALES

The Fund's short sales are subject to special risks. A short sale involves the sale by the Fund of a security that it borrows from a third party in the hope of purchasing the same security at a later date at a lower price. The Fund is then obligated to return the security to the third party, requiring the Fund to purchase the security at the market price at some later date. If the price of the security has increased, 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 cost of the security at the time it is sold short. 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.

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 last five fiscal years ending on August 31, 2004, which run from September 1 to August 31, unless otherwise indicated, and the six-month period ending on February 28, 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 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 is stated in the Annual Fund Operating Expenses tables, is reflected in the chart and is net of any fee waiver or expense reimbursement.

THE FUND

INVESTMENT GOALS

The Fund seeks as high a level of current income and total return as is consistent with prudent risk.

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. government securities, including U.S. treasuries and securities of various U.S. government agencies and instrumentalities. Agency securities include mortgage-backed securities, which represent interests in pools of mortgages. Certain securities of U.S. government agencies and instrumentalities in which the Fund invests are neither issued nor guaranteed by the U.S. Treasury. 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.

The Fund may also invest up to 20% of its assets in corporate bonds or mortgage- or asset-backed securities that are issued by private entities. These securities must be rated investment grade by Moody's Investors Service, Inc., Standard & Poor's or Fitch, Inc.

The Fund has wide flexibility to vary its allocation among different types of U.S. government securities and the securities of non-governmental issuers based on the Fund's investment advisor's judgment of which types of securities will outperform the others. In selecting investments for the Fund, the advisor considers a security's expected income together with its potential to rise or fall in price.

The Fund generally maintains a duration of greater than three years and less than ten years. As a result, the Fund's portfolio has market risks and an expected average life comparable to intermediate- to long-term bonds. The advisor may vary the Fund's duration depending on its forecast of interest rates and market conditions. For example, when interest rates are expected to increase, the advisor may shorten the duration, and vice versa.


UNDERSTANDING DURATION

DURATION is the most common measure of the interest rate risk of a bond. It measures the sensitivity of the bond's price to changes in interest rates. A fund's duration is the average of the durations of the securities in which the fund invests. Generally, the shorter a fund's duration, the less its share price will change when there is a change in interest rates.

The advisor uses duration management to control some of the potential risk of investing in the Fund.

THE FUND

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, 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.

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. All information in this prospectus relating to the Fund for periods prior to September 26, 2005, including the performance information shown below, is that of Columbia Federal Securities Fund, a series of Columbia Funds Trust III, 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.


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 Citigroup Government/Mortgage Index (Citigroup Index), an unmanaged index that is a combination of the Citigroup U.S. Government Index (Government Index) and the Citigroup Mortgage Index (Mortgage Index). The Government Index tracks the performance of the Treasury and Government-Sponsored Indices within the U.S. Broad Investment Grade Bond Index. The Mortgage Index tracks the performance of the mortgage component of the U.S. BIG Bond Index, comprising 30- and 15-year GNMA, FNMA and FHLMC pass-throughs and FNMA and FHLMC balloon mortgages. 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 U.S. Government 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.

(1) Class Z is a newer class of shares. Its performance information includes returns of Class A shares (the oldest existing 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 new 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 new 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 March 30, 1984, and Class Z shares were initially offered on January 11, 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, 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

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 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. (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;

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 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); or

- 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" 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 that are deemed material by the Fund in any 28-day period, the Fund will generally 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 generally 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 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


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 not 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.

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.

Columbia Advisors will be responsible for the Fund's management, subject to oversight by the Fund's Board of Trustees. In its duties as investment advisor, Columbia Advisors will run 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"), an affiliate of Columbia Advisors with offices at the same location, will merge into Columbia Advisors. Columbia Management will be the investment advisor to the Fund until September 30, 2005. As a result of the merger, Columbia Advisors will become 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 0.60% of average daily net assets of 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


16

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 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.

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.

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.

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.

SHORT SALES

The Fund's short sales are subject to special risks. A short sale involves the sale by the Fund of a security that it borrows from a third party in the hope of purchasing the same security at a later date at a lower price. The Fund is then obligated to return the security to the third party, requiring the Fund to purchase the security at the market price at some later date. If the price of the security has increased, 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 cost of the security at the time it is sold short. 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.

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. 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, except for the period ended February 28, 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.

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

(b) Effective September 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 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 and that all dividends and distributions are reinvested. The annual expense ratio used for the Fund, which is the same as that is stated in the Annual Fund Operating Expenses tables, is reflected in the chart and is net of any fee waiver or expense reimbursement.

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.

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 (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;

c

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

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. Invest more than 15% of its net assets in illiquid assets; and

3. 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.

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." 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 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 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 in the Fund's portfolio may result in correspondingly greater brokerage commissions and other transaction costs, which will be borne directly by the Fund.

- 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.

COMPENSATION

As of the 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 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 business 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 PLANS, 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 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 an annual rate of 0.75% of the average daily net assets attributed to its Class B and Class C shares. CMD has voluntarily agreed to waive 0.15% of the Fund's Class C share distribution fees. 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 services 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 indirect financing of the distribution of the Fund's shares.

The Trustees of the Trust 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

k


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 are 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 charge are described in the Prospectus for the Fund's Class A, Class B and Class 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.

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

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 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.

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.

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.

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;

12

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 clearing corporation may not at all times be adequate to handle current trading volume; or (vi) one or more exchanges could, for

13

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

14

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

15

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.

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

18

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. 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

19

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. Treasury securities maturing on a quarterly basis through the conversion date, and a forward purchase contract with an existing

20

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, 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

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, 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.

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.

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.

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.

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 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).

36

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.

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

39

"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.

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.

   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 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

41

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.

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.

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.

43

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 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 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.

47

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.

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.

(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.

49

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. 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.

50

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. 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.

51

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, 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.

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 schedul e 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

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) 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.

56

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 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).

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.

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:

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.

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, 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.

63

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.

64

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);

65

(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.

66

- 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.

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.

68

- 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.

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.

- 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 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.

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.

THE FUND

INVESTMENT GOALS

The Fund seeks current income consistent with prudent risk. The Fund also seeks maximum total return.

PRINCIPAL INVESTMENT STRATEGIES

The Fund seeks to achieve its goals by investing primarily in:

- debt securities issued by the U.S. government, including mortgage-backed securities issued by U.S. government agencies;

- debt securities issued by foreign governments and foreign companies, including securities issued in emerging market countries; and

- lower-rated corporate debt securities.

The Fund's investment advisor allocates the Fund's investments among these types of securities at any given time based on its estimate of the expected performance and risk of each type of investment.

The Fund pursues its investment goals by investing a portion of its assets 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 advisor to be comparable in quality.

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. 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.

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.


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.

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.

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

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.

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.

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 a broad measure 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 26, 2005, including the performance information shown below, is that of Columbia Strategic Income Fund, a series of Columbia Funds Trust I, 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.

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 (Lehman Brothers Index), an unmanaged index that tracks the performance of U.S. government and U.S. corporate 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 Multi-Sector Income 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)

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 April 21, 1977, Class B shares were initially offered on May 15, 1992, and Class C shares were initially offered on July 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.

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) Management fees have been restated to reflect contractual changes effective November 1, 2004.

(2) The annual service fee portion of the 12b-1 fee may equal up to 0.15% on net assets attributable to shares issued prior to January 1, 1993 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 0.15% 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 0.84% and total annual fund operating expenses for Class C shares would be 1.68%. 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.

"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.

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 offers an additional class of shares, Class J shares, which are made available only to residents or citizens of Japan through a separate prospectus.

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 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


11

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 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


12

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. 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.

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


13

YOUR ACCOUNT

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.

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, the Fund will generally 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


15

YOUR ACCOUNT

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 generally 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 is calculated by adding (1) 0.15% on net assets attributable to shares issued prior to January 1, 1993 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 May 31, 2005, the combined service fee was 0.24% 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. 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


16

YOUR ACCOUNT

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 the 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


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. 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 monthly 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.

In its duties as investment advisor, Columbia Advisors will run 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"), an affiliate of Columbia Advisors with offices at the same location, will merge into Columbia Advisors. Columbia Management will be the investment advisor to the Fund until September 30, 2005. As a result of the merger, Columbia Advisors will become the investment advisor to the Fund.

For the 2004 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 0.59% of average daily net assets of the Fund. A discussion of the factors considered by the predecessor fund's Board of Trustees in approving the predecessor fund's investment advisory contract is included in the Fund's annual report to shareholders for the fiscal year ended May 31, 2005.

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


20

MANAGING THE FUND

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 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.


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 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.

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.

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.

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 goals.

Per share data and ratios for periods prior to December 31, 2001 have not been restated to reflect this change in presentation.

(d) Net of fees waived by the distributor which amounted to $0.02 per share and 0.15% for the year ended December 31, 2000.

(e) The per share net investment income amount does not reflect the period's reclassifications of differences between book and tax basis net investment income.

(f) Total return at net asset value assuming all distributions reinvested and no contingent deferred sales charge.

(g) Had the distributor 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.

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.

THE FUND

INVESTMENT GOALS

The Fund seeks current income consistent with prudent risk. The Fund also seeks maximum total return.

PRINCIPAL INVESTMENT STRATEGIES

The Fund seeks to achieve its goals by investing primarily in:

- debt securities issued by the U.S. government, including mortgage-backed securities issued by U.S. government agencies;

- debt securities issued by foreign governments and foreign companies, including securities issued in emerging market countries; and

- lower-rated corporate debt securities.

The Fund's investment advisor allocates the Fund's investments among these types of securities at any given time based on its estimate of the expected performance and risk of each type of investment.

The Fund pursues its investment goals by investing a portion of its assets 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 advisor to be comparable in quality.

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. 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.

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.

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.

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.

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.

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.

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 a broad measure 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 26, 2005, including the performance information shown below, is that of Columbia Strategic Income Fund, a series of Columbia Funds Trust I, 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.

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 (Lehman Brothers Index), an unmanaged index that tracks the performance of U.S. government and U.S. corporate 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 Multi-Sector Income 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.

                                       Worst quarter: 2nd quarter, 2004, -2.13%.

(1) Class Z is a newer class of shares. Its performance information includes returns of 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 April 21, 1977, and Class Z shares were initially offered on January 29, 1999.

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.

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;

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 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 four additional classes of shares -- Class A, B, C and J 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.

Class J shares are available for purchase only by residents or citizens of Japan.

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

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, the Fund will generally 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,


12

YOUR ACCOUNT

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 generally 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.


13

YOUR ACCOUNT

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, subtransfer 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. 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.

YOUR ACCOUNT

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 monthly 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.


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

Effective September 30, 2005, Columbia Management Advisors, LLC ("Columbia Advisors"), located at 100 Federal Street, Boston, Massachusetts 02110, will become the Fund's investment advisor. Columbia Advisors will be responsible for the Fund's management, subject to oversight by the Fund's Board of Trustees. In its duties as investment advisor, Columbia Advisors will run 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"), an affiliate of Columbia Advisors with offices at the same location, will merge into Columbia Advisors. Columbia Management will be the investment advisor to the Fund until September 30, 2005. As a result of the merger, Columbia Advisors will become 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 0.59% of average daily net assets of the Fund. A discussion of the factors considered by the predecessor fund's Board of Trustees in approving the predecessor fund's investment advisory contract is included in the predecessor fund's annual report to shareholders for the fiscal year ended May 31, 2005.

MANAGING 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' 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.


18

MANAGING THE FUND

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.

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.

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.

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.

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 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 Fund's last six fiscal periods, 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.

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 FUND

INVESTMENT GOALS

The Fund seeks current income consistent with prudent risk. The Fund also seeks maximum total return.

PRINCIPAL INVESTMENT STRATEGIES

The Fund seeks to achieve its goals by investing primarily in:

- debt securities issued by the U.S. government, including mortgage-backed securities issued by U.S. government agencies;

- debt securities issued by foreign governments and foreign companies, including securities issued in emerging market countries; and

- lower-rated corporate debt securities.

The Fund's investment advisor allocates the Fund's investments among these types of securities at any given time based on its estimate of the expected performance and risk of each type of investment.

The Fund pursues its investment goals by investing a portion of its assets 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 advisor to be comparable in quality.

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. 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.

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.


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.

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 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.

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

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.

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.

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.

THE FUND

PERFORMANCE HISTORY

The bar chart below shows the Fund's calendar year total returns (before taxes) for its Class J shares, excluding sales charges. The performance table following the bar chart shows how the Fund's average annual total returns for Class J shares, including sales charges, compare with those of a broad measure 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 26, 2005, including the performance information shown below, is that of Columbia Strategic Income Fund, a series of Columbia Funds Trust I, 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.


UNDERSTANDING PERFORMANCE

CALENDAR YEAR TOTAL RETURNS show the Fund's Class J 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 Class J shares and includes the effects of both Fund expenses and current sales charges.

The Fund's returns are compared to the Lehman Brothers Government/Credit Bond Index (Lehman Brothers Index), an unmanaged index that tracks the performance of U.S. government and U.S. corporate 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 Multi-Sector Income 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.

The Class's year-to-date total return         For the periods shown in bar chart:
through June 30, 2005 was +0.04%.             Best quarter: 2nd quarter 2003, +7.47%
                                              Worst quarter: 2nd quarter 2004, -2.25%

THE FUND

After-tax returns are calculated using the historical highest individual U.S. federal marginal income tax rates and do not reflect the impact of Japanese taxes, or any U.S. 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.

(1) Class J is a newer class of shares. Its performance information includes returns of Class A shares (the oldest existing 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 21, 1977 and Class J shares were initially offered on November 2, 1998.

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. 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

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 MINIMUM


The initial investment minimum for the purchase of Class J shares is $1,000. The Fund reserves the right to change this investment minimum. 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 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 one class of shares in this prospectus -- CLASS J.

The Fund also offers additional classes of shares, Class A, B, C and Z shares, which are available through separate prospectuses. These classes are not available for purchase in Japan.

CLASS J SHARES Your purchases of Class J 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. A portion of the sales charge is paid as a commission to your financial advisor on the sale of Class J shares. The amount of the sales charge differs depending on the amount you invest as shown in the table below.

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 J 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 J 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


9

YOUR ACCOUNT

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.

SPECIAL SALES INCENTIVES The distributor, may, at its expense, provide special sales incentives (such as cash payments in addition to the commissions specified in this prospectus) to financial advisors that agree to promote the sale of Class J shares of the Fund or other funds that the distributor distributes. At its discretion, the distributor may offer special sales incentives only to selected financial advisors or to financial advisors that have previously sold or expect to sell significant amounts of Class J shares of the Fund.

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, 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.


10

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 that are deemed material by the Fund in any 28-day period, the Fund will generally 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 generally 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


11

YOUR ACCOUNT

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 J 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 January 1, 1993 and (2) 0.25% on net assets attributable to all 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 May 31, 2005, the combined service fee was 0.24% of the Fund's average net assets. The annual distribution fee may equal up to 0.35% for Class J shares. Distribution and service fees are paid out of the assets of this class. Over time, these fees 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 the 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


12

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 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 U.S. 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 its Class J shares by dividing total net assets attributable to Class J shares by the number of outstanding Class J 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 securities 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 U.S. 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 J 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.

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 monthly 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 FOR U.S. INVESTORS 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 U.S. 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. If you are not subject to U.S. federal income tax, you generally will not have to pay tax on distributions of long-term capital gains. 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 shares of the Fund. Such transactions also may be subject to federal, state and local income tax. If you are not subject to U.S. federal income tax, you generally will not have to pay tax on gains realized upon a disposition of Fund shares.


14

YOUR ACCOUNT

TAX CONSEQUENCES FOR NON-U.S. INVESTORS Non-U.S. investors should consult their tax advisors concerning the tax consequences of ownership of shares of the Fund, including the possibility that distributions may be subject to a 28% U.S. withholding tax (or reduced rate of withholding provided by treaty), the possibility that a non-U.S. investor may be subject to U.S. tax on capital gain distributions and gains realized upon the sale of Fund shares if the investor is present in the United States for more than 182 days during the taxable year (and certain other conditions apply), or the possibility that a non-U.S. investor may be subject to U.S. tax on income from the Fund that is "effectively connected" with a U.S. trade or business carried on by such investor.

The Fund is generally required to withhold 28% of any redemption proceeds and all income dividends and capital gain distributions it pays (i) if an investor does not provide a correct, certified taxpayer identification number, (ii) if the Fund is notified that an investor has underreported income in the past, or
(iii) if an investor fails to certify to the Fund that he or she is not subject to withholding. The back-up withholding rate will be 31% for amounts after December 31, 2010. Special withholding rules may apply to non-U.S. shareholders. In order to avoid backup withholding, a non-U.S. investor must provide documentation that proves such investor is not a U.S. person who would be subject to those rules. Additional certifications are necessary if a non-U.S. investor wishes to obtain reduced withholding rates under a treaty.

The Internal Revenue Service revised its regulations affecting the application to foreign investors of the back-up withholding and withholding tax rules described above. The new regulations are generally effective for payments made on or after January 1, 2001 (although transition rules will apply). In some circumstances, the new rules will increase the certification and filing requirements imposed on foreign investors in order to qualify for exemption from the 28% back-up withholding tax and for reduced withholding tax rates under income tax treaties. Foreign investors in the Fund should consult their tax advisors with respect to the potential application of these new regulations.

MANAGING 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' 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.

MANAGING THE FUND

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.

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.

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.

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.

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 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 J 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.

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; and

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 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 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

c

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 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; and

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.

So long as shares of the Fund are being offered for sale in Japan, the Strategic Income Fund will not invest in equity securities.

If any violation of the foregoing standards occurs, the 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 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." 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 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 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

Under the Fund's Management Agreement with the Advisor, the Fund pays the Advisor a monthly fee 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.

Prior to November 1, 2004, under the Fund's Investment Advisory 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% on the first $1 billion, 0.60% of the next $1 billion and 0.55% in excess of $2 billion.

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 a 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.

d

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 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:

- 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.

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 five classes of shares - Class A, Class B, Class C, Class J 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 for Class Z. Under the Plan, the 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. The 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 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 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 the Fund 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 which could benefit each class of the 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 for periods up to 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

l

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 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 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.

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

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 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.

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.

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.

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;

12

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 clearing corporation may not at all times be adequate to handle current trading volume; or (vi) one or more exchanges could, for

13

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

14

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

15

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.

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

18

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. 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

19

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. Treasury securities maturing on a quarterly basis through the conversion date, and a forward purchase contract with an existing

20

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, 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

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.

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.

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.

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.

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.

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 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).

36

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.

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.

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.

40

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 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 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

41

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.

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.

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.

43

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 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 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.

47

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.

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.

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:

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.

50

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.

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. 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.

51

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, 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.

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 schedul e 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

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 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.

56

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 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).

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.

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:

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.

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, 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.

63

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.

64

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);

65

(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.

66

- 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.

67

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.

68

- 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.

69

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.

THE FUND

INVESTMENT GOAL

The Fund seeks to provide investors with current income, exempt from federal income tax, consistent with preservation of capital.

PRINCIPAL INVESTMENT STRATEGIES

The Fund invests primarily in a diversified portfolio of municipal securities, which are securities issued by state and local governments and other political or public bodies or agencies and that pay interest which is exempt from federal income tax (including the federal alternative minimum tax). The Fund normally invests at least 80% of its net assets (plus any borrowings for investment purposes) in municipal securities and mutual funds that invest in municipal securities. The Fund may also invest up to 20% of its net assets in debt securities that pay interest that is not exempt from federal income tax, such as U.S. Government obligations, corporate bonds, money market instruments, including commercial paper and bank obligations, and repurchase agreements.

Municipal securities purchased by the 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.

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.


A DERIVATIVE is an investment whose value is based on or derived from the performance of other securities or interest or currency exchange rates or indices. Derivatives are considered to carry a higher degree of risk than other types of securities.

In selecting portfolio securities for the Fund, the Fund's investment advisor evaluates the suitability of available bonds according to such factors as creditworthiness, maturity, liquidity and interest rates. It also determines the appropriate allocation of the Fund's assets among various geographic regions, issuers and industry sectors.

Nearly all of the Fund's investments will be of investment grade quality. These are securities which have one of the top four ratings assigned by Standard & Poor's (S&P) or Moody's Investors Service, Inc. (Moody's), or are unrated securities determined by the advisor to be of comparable quality. The advisor expects, however, that most of the securities purchased by the Fund will have one of the top three ratings assigned by S&P or Moody's, or will be 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 rated debt securities that are not rated investment grade by either S&P or Moody's (or determined by the advisor to be of investment grade quality) to the extent such securities exceed 5% of the Fund's net assets.


2

THE FUND

The Fund is permitted to invest in municipal securities with any maturity. However, under normal circumstances, the Fund's average weighted maturity will be between five and ten years. 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.

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.

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.

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 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 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.

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

THE FUND

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.

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 source. 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 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.

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 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. All information in this prospectus relating to the Fund for periods prior to September 26, 2005, including the performance information shown below, is that of Columbia Intermediate Tax-Exempt Bond 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. Except as noted below, 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 Blend Index), an unmanaged index that tracks the performance of municipal bonds. 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 Intermediate Tax-Exempt Bond Fund (the Galaxy 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. Retail A Share returns include returns for BKB Shares of the Galaxy Fund for periods prior to June 26, 2001, the date on which BKB Shares were converted into Retail A Shares, and returns of shares of the Boston 1784 Tax-Exempt Medium-Term Income Fund, the predecessor to the Galaxy Fund (the Boston 1784 Fund), for periods prior to the inception of BKB Shares (June 26, 2000). Class A shares generally would have had substantially similar annual 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 exceed expenses paid by Retail A Shares, BKB Shares and shares of the Boston 1784 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, 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 0.47% and an administration fee of 0.07%. Management fees have 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 fees for Class C shares. If this waiver were reflected in the table, the 12b-1 fees for Class C shares would be 0.40% and the total annual fund operating expenses would be 1.04%. This arrangement may be modified or terminated by the distributor at any time.

(3) The Fund's advisor has agreed to reimburse the Fund for certain expenses so that total annual fund operating expenses (exclusive of distribution and service fees, brokerage commissions, interest, taxes and extraordinary expenses, if any) will not exceed 0.50% for one year following the consummation of the merger of Nations Intermediate Municipal Bond Fund, Nations Kansas Municipal Income Fund, Columbia Pennsylvania Intermediate Municipal Bond Fund, and Nations Tennessee Intermediate Municipal Bond Fund into the Fund. If this reimbursement were reflected in the table, total annual fund operating expenses for Class A, B, and C shares would be 0.70%, 1.35%, and 0.90%, respectively (taking into consideration the 12b-1 waiver discussed in footnote (2) above).

(4) Other expenses have been restated to reflect changes to the transfer agency fees for the Fund effective January 1, 2004.

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.

The Fund reserves the right to change these investment minimums. The Fund also reserves the right

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 it's 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.

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 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


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 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


12

YOUR ACCOUNT

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 charts 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.

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 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), Columbia Funds may, in its discretion, reject future purchase orders by the person, group or account, including


15

YOUR ACCOUNT

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, 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.

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 0.20% for each of Class A, Class B and Class C shares. The annual distribution fee may equal up to 0.65% 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 the distribution and service fees will 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 a certain number of years, eliminating the distribution fee upon conversion. Conversion may occur three, four or eight


16

YOUR ACCOUNT

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 the Fund or other 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

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.

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 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.

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

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.

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

Effective September 30, 2005, Columbia Management Advisors, LLC ("Columbia Advisors"), located at 100 Federal Street, Boston, Massachusetts 02110, will become the Fund's investment advisor. Columbia Advisors will be responsible for the Fund's management, subject to oversight by the Fund's Board of Trustees. In its duties as investment advisor, Columbia Advisors will run 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"), an affiliate of Columbia Advisors with offices at the same location, will merge into Columbia Advisors. Columbia Management will be the investment advisor to the Fund until September 30, 2005. As a result of the merger, Columbia Advisors will become the investment advisor to the Fund.

For the 2004 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 0.55% 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 semi-annual report to shareholders for the period ended April 30, 2005.

PORTFOLIO MANAGER

Susan Sanderson, vice president of Columbia Management, is the manager of the Fund and has managed the Fund since June 2002. Ms. Sanderson has been associated with Columbia Management or its predecessors since 1985.

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


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, 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.

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.

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, reinvesting all dividends and distributions and converting Class B to A shares after eight years. The annual expense ratio used for the Fund, which is the same as that is stated in the Annual Fund Operating Expenses tables, is reflected in the chart and is net of any fee waiver or expense reimbursement.

THE FUND

INVESTMENT GOAL

The Fund seeks to provide investors with current income, exempt from federal income tax, consistent with preservation of capital.

PRINCIPAL INVESTMENT STRATEGIES

The Fund invests primarily in a diversified portfolio of municipal securities, which are securities issued by state and local governments and other political or public bodies or agencies and that pay interest which is exempt from federal income tax (including the federal alternative minimum tax). The Fund normally invests at least 80% of its net assets (plus any borrowings for investment purposes) in municipal securities and mutual funds that invest in municipal securities. The Fund may also invest up to 20% of its net assets in debt securities that pay interest that is not exempt from federal income tax, such as U.S. Government obligations, corporate bonds, money market instruments, including commercial paper and bank obligations, and repurchase agreements.

Municipal securities purchased by the 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.

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.


A DERIVATIVE is an investment whose value is based on or derived from the performance of other securities or interest or currency exchange rates or indices. Derivatives are considered to carry a higher degree of risk than other types of securities.

In selecting portfolio securities for the Fund, the Fund's investment advisor evaluates the suitability of available bonds according to such factors as creditworthiness, maturity, liquidity and interest rates. It also determines the appropriate allocation of the Fund's assets among various geographic regions, issuers and industry sectors.

Nearly all of the Fund's investments will be of investment grade quality. These are securities which have one of the top four ratings assigned by Standard & Poor's (S&P) or Moody's Investors Service, Inc. (Moody's), or are unrated securities determined by the advisor to be of comparable quality. The advisor expects, however, that most of the securities purchased by the Fund will have one of the top three ratings assigned by S&P or Moody's, or will be 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 rated debt securities that are not rated investment grade by either S&P or Moody's (or determined by the advisor to be of investment grade quality) to the extent such securities exceed 5% of the Fund's net assets.


2

THE FUND

The Fund is permitted to invest in municipal securities with any maturity. However, under normal circumstances, the Fund's average weighted maturity will be between five and ten years. 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.

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.

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.

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 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 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.

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

THE FUND

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.

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 source. 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 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.

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 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. All information in this prospectus relating to the Fund for periods prior to September 26, 2005, including the performance information shown below, is that of Columbia Intermediate Tax-Exempt Bond Fund, a series of Columbia Funds Trust V, the predecessor to the Fund. The

THE FUND

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 Lehman Brothers 3-15 Year Blend Municipal Bond Index (Lehman Blend Index), an unmanaged index that tracks the performance of municipal bonds. Unlike the Fund, indices are not investments, do not incur fees, expenses or taxes and are not professionally managed.

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 1, 2001). Class G 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 G shares exceed expenses paid by Retail A Shares. Retail A Share returns include returns for BKB Shares of the Galaxy Fund for periods prior to June 26, 2001, the date on which BKB Shares were converted into Retail A Shares, and returns of shares of the Boston 1784 Fund (whose shares were initially offered on June 14, 1993) for periods prior to the inception of BKB Shares (June 26, 2000).

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.

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

(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 0.15% during the current fiscal year.

(5) The Fund's advisor has agreed to reimburse the Fund for certain expenses so that total annual fund operating expenses (exclusive of distribution and service fees, brokerage commissions, interest, taxes and extraordinary expenses, if any) will not exceed 0.50% for one year following the consummation of the merger of Nations Intermediate Municipal Bond Fund, Nations Kansas Municipal Income Fund, Columbia Pennsylvania Intermediate Municipal Bond Fund, and Nations Tennessee Intermediate Municipal Bond Fund into the Fund. If this reimbursement were reflected in the table, total annual fund operating expenses for Class T and G shares would be 0.65% and 1.30%, respectively.

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 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.

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.

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 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.

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.

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 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 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 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

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 service 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 0.80% 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. Class G shares automatically convert to Class T shares after a certain number of years, eliminating a portion of these fees upon conversion. Conversion may occur six or 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 schedule 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 the Fund or other 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


17

YOUR ACCOUNT

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 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

Effective September 30, 2005, Columbia Management Advisors, LLC ("Columbia Advisors"), located at 100 Federal Street, Boston, Massachusetts 02110, will become the Fund's investment advisor. Columbia Advisors will be responsible for the Fund's management, subject to oversight by the Fund's Board of Trustees. In its duties as investment advisor, Columbia Advisors will run 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"), an affiliate of Columbia Advisors with offices at the same location, will merge into Columbia Advisors. Columbia Management will be the investment advisor to the Fund until September 30, 2005. As a result of the merger, Columbia Advisors will become the investment advisor to the Fund.

For the 2004 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 0.55% 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 semi-annual report to shareholders for the period ended April 30, 2005.

PORTFOLIO MANAGER

Susan Sanderson, vice president of Columbia Management, is the manager of the Fund and has managed the Fund since June, 2002. Ms. Sanderson has been associated with Columbia Management or its predecessors since 1985.

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


20

MANAGING THE FUND

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.

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.

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 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 tables, is reflected in the chart and is net of any fee waiver or expense reimbursement.

THE FUND

INVESTMENT GOAL

The Fund seeks to provide investors with current income, exempt from federal income tax, consistent with preservation of capital.

PRINCIPAL INVESTMENT STRATEGIES

The Fund invests primarily in a diversified portfolio of municipal securities, which are securities issued by state and local governments and other political or public bodies or agencies and that pay interest which is exempt from federal income tax (including the federal alternative minimum tax). The Fund normally invests at least 80% of its net assets (plus any borrowings for investment purposes) in municipal securities and mutual funds that invest in municipal securities. The Fund may also invest up to 20% of its net assets in debt securities that pay interest that is not exempt from federal income tax, such as U.S. Government obligations, corporate bonds, money market instruments, including commercial paper and bank obligations, and repurchase agreements.

Municipal securities purchased by the 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.

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 municipal securities.


A DERIVATIVE is an investment whose value is based on or derived from the performance of other securities or interest or currency exchange rates or indices. Derivatives are considered to carry a higher degree of risk than other types of securities.

In selecting portfolio securities for the Fund, the Fund's investment advisor evaluates the suitability of available bonds according to such factors as creditworthiness, maturity, liquidity and interest rates. It also determines the appropriate allocation of the Fund's assets among various geographic regions, issuers and industry sectors.

Nearly all of the Fund's investments will be of investment grade quality. These are securities which have one of the top four ratings assigned by Standard & Poor's (S&P) or Moody's Investors Service, Inc. (Moody's), or are unrated securities determined by the advisor to be of comparable quality. The advisor expects, however, that most of the securities purchased by the Fund will have one of the top three ratings assigned by S&P or Moody's, or will be 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 rated debt securities that are not rated investment grade by either S&P or Moody's (or determined by the advisor to be of investment grade quality) to the extent such securities exceed 5% of the Fund's net assets.


2

THE FUND

The Fund is permitted to invest in municipal securities with any maturity. However, under normal circumstances, the Fund's average weighted maturity will be between five and ten years. 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.

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.

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.

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 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 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 obligations, 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.

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


3

THE FUND

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.

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 source. 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 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.

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. 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 a broad measure of market performance for one year, five years and 10 years. All information in this prospectus relating to the Fund for periods prior to September 26, 2005, including the performance information shown below, is that of Columbia Intermediate Tax-Exempt Bond 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

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 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 3 - 15 year Blend Municipal Bond Index (Lehman Brothers Index), an unmanaged index that tracks the performance of municipals bonds. 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 Z shares include the returns of Trust Shares of the Galaxy Intermediate Tax-Exempt Bond Fund (the Galaxy Fund), the predecessor to the Fund, for periods prior to November 25, 2002, the date on which Class Z shares were initially offered and returns of shares of the Boston 1784 Tax-Exempt Medium-Term Income Fund, the predecessor to the Galaxy Fund (the Boston 1784 Fund), for periods prior to the inception of the Trust Shares (June 26, 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

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 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

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 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)

YOUR ACCOUNT

(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 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 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, the Fund will generally 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 generally 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 the Fund or other 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, subtransfer 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 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. 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 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

Effective September 30, 2005, Columbia Management Advisors, LLC ("Columbia Advisors"), located at 100 Federal Street, Boston, Massachusetts 02110, will become the Fund's investment advisor. Columbia Advisors will be responsible for the Fund's management, subject to oversight by the Fund's Board of Trustees. In its duties as investment advisor, Columbia Advisors will run 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"), an affiliate of Columbia Advisors with offices at the same location, will merge into Columbia Advisors. Columbia Management will be the investment advisor to the Fund until September 30, 2005. As a result of the merger, Columbia Advisors will become the investment advisor to the Fund.

For the 2004 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 0.55% 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 semi-annual report to shareholders for the period ended April 30, 2005.

PORTFOLIO MANAGERS

SUSAN SANDERSON, vice president of Columbia Management, is the manager for the Fund and has managed the Fund since June, 2002. Ms. Sanderson has been associated with Columbia Management or its predecessors since 1985.

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


17

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 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.

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.

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 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 tables, is reflected in the chart and is net of any fee waiver or expense reimbursement.

ORGANIZATION AND HISTORY

The Trust is a Massachusetts business trust organized in 1987. The Fund is an open-end, diversified management investment company representing the entire interest in a separate series of the Trust. The Fund is expected to commence investment operations as a series of the Trust on September 26, 2005. Prior to September 26, 2005 (the "Fund Reorganization Date"), the Fund was organized as a series of Columbia Funds Trust V, a Massachusetts business trust (the "Predecessor Fund") that commenced business operations as a separate portfolio of the Boston 1784 Funds. The information provided for the Fund in this SAI for periods prior to the Fund Reorganization Date relates to the Predecessor Fund.

The Trust 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 Trust was changed from "Columbia Funds Trust IX" to its current name.

The Fund offers six classes of shares - A, B, C, G, T and Z shares.

Except as indicated below under "Fundamental and Non-Fundamental Investment Policies," the Fund's investment policies are not fundamental, and the Trustees may change the policies without shareholder approval.

FUNDAMENTAL AND NON-FUNDAMENTAL INVESTMENT POLICIES

In addition to the 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 the Fund without the affirmative vote of the holders of a majority of its outstanding shares. The Investment Company Act of 1940, as amended (the "1940 Act") provides that a "vote of the holders of a majority of the outstanding shares" of the Fund means the affirmative vote of the holders of the lesser of (a) more than 50% of the outstanding shares of the Fund, or (b) 67% or more of the shares of the Fund present at a meeting if more than 50% of the outstanding shares of the Fund are represented at the meeting in person or by proxy.

As a matter of fundamental policy that cannot be changed without the requisite consent of the Fund's shareholders, the Fund will invest, except during temporary defensive periods, at least 80% of its net assets (plus any borrowings for investment purposes) in 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 Municipal Securities, in which case the Fund's investment in such entity shall be deemed to be an investment in the underlying Municipal Securities in the same proportion as such entity's investment in such Municipal Securities bears to its net assets.

ADDITIONAL FUNDAMENTAL INVESTMENT POLICIES

The Fund may not, as a matter of fundamental policy:

c

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 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 thereunder and any applicable exemptive relief; and

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 following investment limitations with respect to the Fund may be changed by the Trust's Board of Trustees without shareholder approval:

1. The 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. The 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. The Fund may not purchase securities of companies for the purpose of exercising control.

4. The Fund may not purchase the securities of other investment companies except as permitted by the 1940 Act.

5. The Fund may invest in warrants.

d

6. The Fund may invest in illiquid securities in an amount not exceeding, in the aggregate, 15% of the Fund's net assets.

7. The Fund may not 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.

8. The Fund may invest in interests in oil, gas or other mineral exploration or development programs. The Fund may not invest in oil, gas or mineral leases.

Municipal Securities purchased by the Fund 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 the 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 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 the 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.

The 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, although the Fund does not presently intend to do so on a regular basis. To the extent that the 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 Fund 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, with respect to the Fund, 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 Fund 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 Fund's 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 the Fund's total assets when added together with any taxable investments held by the Fund.

The Fund currently intends to limit the lending of its portfolio securities so that, at any given time, securities loaned by the Fund represent not more than one-third of the value of its total assets.

The 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; the Fund will limit its purchase, together with other securities considered to be illiquid, to 15% of its net assets.

The Fund currently 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 the 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 Fund does not intend to engage in when-issued purchases, forward commitments and delayed settlements for speculative purposes, but only in furtherance of its investment goals.

e


The Fund will not invest more than 10% of its total assets in asset-backed securities.

The 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.

The 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. The Fund will not enter into repurchase agreements with the Advisor or any of its affiliates. Investments by the Fund in repurchase agreements will be, under normal market conditions, subject to the Fund's 20% overall limit on taxable obligations.

The Fund may write covered call options provided that the aggregate value of such options does not exceed 10% of the Fund's net assets as of the time the Fund enters into such options. The Fund may write covered call options for hedging purposes only and will not engage in option writing strategies for speculative purposes.

Subject to applicable laws, the Fund may enter into bond and interest rate futures contracts and, for hedging purposes only, purchase and write options on futures contracts. The Fund intends to use futures contracts only for bona fide hedging purposes.

Because the Fund may buy and sell securities denominated in currencies other than the U.S. dollar, the Fund 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. The Fund also may engage in currency swaps.

The Fund may invest in securities issued by other investment companies and foreign investment trusts. The Fund 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 the Fund's portfolio securities generally will not constitute a violation of the limitation. If the value of the 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 the 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.

The 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.

PORTFOLIO TURNOVER

Portfolio turnover is included in the Prospectuses 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. The Fund seeks to maintain a low portfolio turnover rate, although the Fund may engage in higher portfolio turnover in order to reduce shareholder exposure to taxes (such as when the Advisor sells securities to create a loss to offset gains realized on other securities).

FUND CHARGES AND EXPENSES

Under the Fund's management agreement with the Advisor, the Fund pays the Advisor a monthly fee at the annual rate of:

f


             Average Daily Net Assets                             Rate

COMPENSATION

As of the 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 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.

BROKERAGE COMMISSIONS

There were no commissions paid on transactions by any of the Fund during the past fiscal year. See "Management of the Funds - Portfolio Transactions - Brokerage and research services" in Part 2 of this SAI.

The Trust is required to identify any securities of its "regular brokers or dealers" that the Fund has acquired during its most recent fiscal year. At October 31, 2004, the Fund did not hold securities of its regular brokers or dealers.

Prior to July 22, 2002, PFPC Distributors was also entitled to the payment of contingent deferred sales charges upon the redemption of Retail B Shares of the Fund.

12B-1 PLAN, SHAREHOLDER SERVICING PLAN, CDSCS AND CONVERSION OF SHARES

The Fund offers Class A, Class B, Class C, Class T, Class G and Class Z shares. 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 Act. Under the Plan, the Fund pays CMD monthly a service fee at an annual rate of 0.20% of the Fund's average daily net assets attributed to Class A, B and C shares.

The Fund also pays CMD monthly a distribution fee at an annual rate of 0.65% of the Fund's average daily net assets attributed to Class B and Class C shares.

The Fund may pay CMD distribution and service 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

n


and up to 0.25% for administrative support services). The 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 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 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 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 Fund are subject to a shareholder servicing fee pursuant to a Shareholder Servicing Plan. Under the Shareholder Servicing Plan, the 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 Fund.

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 the 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 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 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 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, 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

o


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.

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. 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

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.

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.

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.

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.

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;

12

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 clearing corporation may not at all times be adequate to handle current trading volume; or (vi) one or more exchanges could, for

13

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

14

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

15

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.

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, 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

18

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. 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

19

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. Treasury securities maturing on a quarterly basis through the conversion date, and a forward purchase contract with an existing

20

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, 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

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, 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.

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.

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.

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.

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 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).

36

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.

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.

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.

40

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 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 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

41

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.

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.

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.

43

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 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 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.

47

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.

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.

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:

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.

50

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.

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. 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.

51

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, 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.

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 schedul e 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

-----------------------------   ---------------
Through first year                    5.00
Through second year                   4.00
Through third year                    3.00
Through fourth year                   3.00

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

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) 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.

56

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 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).

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.

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:

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.

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, 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.

63

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.

64

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);

65

(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.

66

- 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.

67

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.

68

- 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.

69

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.

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


2

THE FUNDS -- COLUMBIA TAX-EXEMPT FUND

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.

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.

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.

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.

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


3

THE FUNDS -- COLUMBIA TAX-EXEMPT FUND

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 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. 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 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 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.

(1) Class C is a newer class of shares. Its performance information includes returns of 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 A shares were initially offered on November 21, 1978, 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.

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) Management fees have 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 0.80% and total annual fund operating expenses for Class C shares would be 1.45%. This arrangement may be modified or terminated by the distributor at any time.

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.

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.

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.

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.

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

THE FUNDS -- COLUMBIA TAX-EXEMPT INSURED FUND

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.

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 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 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 Insured 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.

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 November 20, 1985, Class B shares were initially offered on May 5, 1992 and Class C shares were initially offered on August 1, 1997.

THE FUNDS -- COLUMBIA TAX-EXEMPT INSURED 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.

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 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.

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 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:

YOUR ACCOUNT


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

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


18

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 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 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. 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 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 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,


22

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 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, 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 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 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. 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 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


24

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.

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.

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 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.

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

YOUR ACCOUNT

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

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 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.

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 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.

MANAGING THE FUNDS

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

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 goals, 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 goals. 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.

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.

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.

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.

OTHER INVESTMENT STRATEGIES AND RISKS

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.

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 and, for Columbia Tax-Exempt Fund, for the six-month period ending on May 31, 2005. 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 Funds (assuming reinvestment of all dividends and distributions). This information is included in the Funds' financial statements which, except for the period ended May 31, 2005, 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 provisions of the AICPA Audit and Accounting Guide for Investment Companies and began accreting market discount on all debt securities.

(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) The per share net investment income amount does not reflect the period's reclassification of differences between book and tax basis net investment income.

(d) Total return at net asset value assuming all distributions reinvested and no contingent deferred sales charge.

(e) Had the investment advisor/distributor not waived a portion of expenses, total return would have been reduced.

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

(g) Not annualized.

(h) 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 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, reinvesting all dividends and distributions and converting Class B to A shares after eight years. The annual expense ratio used for the Funds, which is the same as that is stated in the Annual Fund Operating Expenses tables, is reflected in the chart and is net of any fee waiver or expense reimbursement.

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 books): (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 that 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


2

THE FUND -- COLUMBIA TAX-EXEMPT FUND

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.

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.

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.

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. For more information on the risks of derivative strategies, see the Statement of Additional Information.

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.

THE FUND -- COLUMBIA TAX-EXEMPT 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 excluding sales charges. 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 10 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.


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 10-year periods. They include the effects of Fund expenses.

The Fund's returns are compared to the Lehman Brothers Government/Credit Bond Index (Lehman Brothers Index), an unmanaged index that tracks the performance of U.S. government and U.S. corporate 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 Multi-Sector Income 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.

                                       Worst quarter: 2nd quarter, 2004, -3.01%.

(1) Class Z is a newer class of shares. Its performance information consists of returns of 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 would have been higher, since Class Z shares are not subject to any Rule 12b-1 fees.

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.

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 arrangement 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 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 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.

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 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 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 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 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, the Fund will generally 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 generally 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 the Fund or other 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, subtransfer 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 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. 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

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


14

YOUR ACCOUNT

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

Effective September 30, 2005, Columbia Management Advisors, LLC ("Columbia Advisors"), located at 100 Federal Street, Boston, Massachusetts 02110, will become the Fund's investment advisor. Columbia Advisors will be responsible for the Fund's management, subject to oversight by the Fund's Board of Trustees. In its duties as investment advisor, Columbia Advisors will run 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"), an affiliate of Columbia Advisors with offices at the same location, will merge into Columbia Advisors. Columbia Management will be the investment advisor to the Fund until September 30, 2005. As a result of the merger, Columbia Advisors will become the investment advisor to the Fund.

For the 2004 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 semi-annual report to shareholders for the period ended May 31, 2005.

PORTFOLIO MANAGERS

KIMBERLY CAMPBELL, a senior vice president of Columbia Management, is the manager for the Columbia Tax-Exempt Fund and has managed the Columbia Tax-Exempt Fund since May, 2004 and served as a portfolio manager from January, 2002 to March, 2004.

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.


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, 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.

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


17

MANAGING THE FUND

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 Risk." 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.

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.

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.

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.

OTHER INVESTMENT STRATEGIES AND RISKS

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.

INVERSE FLOATING 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 goals.

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

(b) Effective December 1, 2001, the Fund adopted the provisions of the AICPA Audit and Accounting Guide for Investment Companies and began accreting market discount on all debt securities.

The impact to the net investment income and 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) The per share net investment income amount does not reflect the period's reclassification of differences between book and tax basis net investment income.

(d) Total return at net asset value assuming all distributions reinvested and no initial sales charge or contingent deferred sales charge.

(e) Had the investment advisor not waived a portion of expenses, total return would have been reduced.

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

(g) Not annualized.

(h) Annualized.

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 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 tables, is reflected in the chart and is net of any fee waiver or expense reimbursement.

ORGANIZATION AND HISTORY

The Trust is a Massachusetts business trust organized in 1987.

The information provided for the Fund in this SAI for periods prior to the Fund Reorganization Date relates to the Predecessor Fund.

Effective October 13, 2003, the name of the Trust was changed from "Liberty-Stein Roe Funds Managed Trust" to "Columbia Funds Trust IX." Effective September 19, 2005, the name of the Trust changed from "Columbia Funds Trust IX to its current name."

The Fund offers four classes of shares - Class A, B, C and Z shares.

FUNDAMENTAL INVESTMENT POLICIES

The Investment Company Act of 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 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.

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;

In addition to the above listed fundamental investment policies, the 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, 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.

Notwithstanding the investment policies and restrictions of the Fund, the 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. For the purpose of the 1940 Act diversification requirement, an issuer is the entity whose revenues support the security.

COMPENSATION

As of the 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,

i

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 and peer group 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 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 except for Class Z shares. Under the Plan, the Fund pays CMD monthly a service fee at an annual rate of 0.20% of net assets attributed to each Class of shares. The 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% 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 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 the Funds' 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 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 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 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. The CDSCs are described in the Prospectus.

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

k


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.

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

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 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.

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.

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.

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;

12

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 clearing corporation may not at all times be adequate to handle current trading volume; or (vi) one or more exchanges could, for

13

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

14

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

15

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.

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

18

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. 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

19

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. Treasury securities maturing on a quarterly basis through the conversion date, and a forward purchase contract with an existing

20

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, 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

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, 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.

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.

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.

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.

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 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).

36

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.

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

39

"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.

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.

   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 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

41

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.

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.

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.

43

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 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 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.

47

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.

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.

(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.

49

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. 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.

50

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. 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.

51

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, 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.

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 schedul e 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

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) 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.

56

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 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).

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.

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:

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.

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, 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.

63

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.

64

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);

65

(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.

66

- 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.

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.

67

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.

68

- 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.

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.

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.

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.

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.

THE FUNDS

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.

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.

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 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.

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.

COLUMBIA CALIFORNIA 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 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.

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) 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.

(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 0.66% and total annual fund operating expenses for Class C shares would be 1.32%. This arrangement may be modified or terminated by the distributor at any time.

(3) The Fund's advisor has agreed to reimburse the Fund for certain expenses so that 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% for one year following the consummation of the merger of Nations California Municipal Bond Fund into the Fund. If this reimbursement were reflected in the table, total annual fund operating expenses for Class A, B, and C shares would be 0.81%, 1.56%, and 1.26%, respectively (taking into consideration the 12b-1 waiver discussed in footnote (2) above).

COLUMBIA CONNECTICUT 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 Connecticut 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.

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.

(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 1.28% (taking into account the fee waiver discussed in footnote 1 above). This arrangement may be modified or terminated by the distributor at any time.

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.

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

(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 0.67% and total annual fund operating expenses for Class C shares would be 1.36%. This arrangement may be modified or terminated by the distributor at any time.

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.

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.

(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 0.37% and total annual fund operating expenses for Class A, B and C shares would be 0.83%, 1.58% and 1.28%, 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 1.28% (taking into account the fee waiver discussed in footnote 1 above). 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 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.

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 a 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 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 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 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 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 and at www.columbiafunds.com.


24

YOUR ACCOUNT

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 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. A Fund may terminate your exchange privilege if the advisor


25

YOUR ACCOUNT

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 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,


27

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 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 the Funds nor their agents shall be held liable for any loss resulting from rejected purchase orders or exchanges.

DISTRIBUTION AND SERVICE FEES

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, 2004, each Fund's combined service fee was the following


28

YOUR ACCOUNT

percentage of each Fund's average net assets: California Tax-Exempt Fund 0.21%; Connecticut Tax-Exempt Fund 0.23%; Massachusetts Tax-Exempt Fund 0.22% and New York Tax-Exempt Fund 0.23%. 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. 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 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 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


29

YOUR ACCOUNT

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.

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


30

YOUR ACCOUNT

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 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 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

Effective September 30, 2005, Columbia Management Advisors, LLC ("Columbia Advisors"), located at 100 Federal Street, Boston, Massachusetts 02110, will become the Fund's investment advisor. Columbia Advisors will be responsible for the Fund's management, subject to oversight by the Fund's Board of Trustees. In its duties as investment advisor, Columbia Advisors will run 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"), an affiliate of Columbia Advisors with offices at the same location, will merge into Columbia Advisors. Columbia Management will be the investment advisor to the Fund until September 30, 2005. As a result of the merger, Columbia Advisors will become the investment advisor to the Fund.

For the 2004 fiscal year, aggregate advisory fees paid to Columbia Management 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 administration, pricing and bookkeeping, and other fees paid to Columbia Management 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' semi-annual reports to shareholders for the period ended April 30, 2005.

PORTFOLIO MANAGER

GARY SWAYZE, a senior vice president of Columbia Management, is the portfolio 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.

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.


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 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.

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

MANAGING THE FUNDS

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

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.

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 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


35

OTHER INVESTMENT STRATEGIES AND RISKS

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 result in a delay in recovery or the failure to fully recover the Fund's original investment.

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.

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.

(a) The Fund changed its fiscal year end from January 31 to October 31.

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

(c) Effective February 1, 2001, the Fund adopted the provisions 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 January 31, 2002, was to increase the ratio of net investment income to average net assets from 4.10% to 4.16%. 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 January 31, 2002 have not been restated to reflect this change in presentation.

(d) The per share net investment income amount does not reflect the period's reclassifications of differences between book and tax basis net investment income.

(e) Total return at net asset value assuming all distributions reinvested and no contingent deferred sales charge.

(f) Had the investment advisor and/or any of its affiliates not waived or reimbursed a portion of expenses, total return would have been reduced.

(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.

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, reinvesting all dividends and distributions and converting Class B 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 chart and is net of any fee waiver or expense reimbursement.

THE FUND

INVESTMENT GOALS

The Fund seeks as high a level of after-tax total return as is consistent with prudent risk.

PRINCIPAL INVESTMENT STRATEGIES

The 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, the 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 the 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.

The 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.

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 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 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.

THE FUND

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.

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.

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.

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 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.

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. 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 a broad measure of market performance for 1 year, 5 years and 10 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. 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 Government/Credit Bond Index (Lehman Brothers Index), an unmanaged index that tracks the performance of U.S. government and U.S. corporate 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 Multi-Sector Income 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.

                                       Worst quarter: 2nd quarter, 2004, -2.92%.

(1) Class Z is a newer class of shares. Its performance information consists of returns of 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 would have been higher, since Class Z shares are not subject to any Rule 12b-1 fees.

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

(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.

(2) The Fund's advisor has agreed to reimburse the Fund for certain expenses so that 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% for one year following the consummation of the merger of Nations California Municipal Bond Fund into the Fund. If this reimbursement were reflected in the table, total annual fund operating expenses for Class Z shares would be 0.60%.

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 the 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 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.

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 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 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, the Fund will generally 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 generally 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, subtransfer 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 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


13

YOUR ACCOUNT

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.

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

Effective September 30, 2005, Columbia Management Advisors, LLC ("Columbia Advisors"), located at 100 Federal Street, Boston, Massachusetts 02110, will become the Fund's investment advisor. Columbia Advisors will be responsible for the Fund's management, subject to oversight by the Fund's Board of Trustees. In its duties as investment advisor, Columbia Advisors will run 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"), an affiliate of Columbia Advisors with offices at the same location, will merge into Columbia Advisors. Columbia Management will be the investment advisor to the Fund until September 30, 2005. As a result of the merger, Columbia Advisors will become the investment advisor to the Fund.

For the 2004 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 0.50% 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 semi-annual report to shareholders for the period ended April 30, 2005.

PORTFOLIO MANAGERS

GARY SWAYZE, a senior vice president of Columbia Management, is the portfolio manager for the Fund and has managed the Fund since October, 1997.

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,


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, 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.

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.


17

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.

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 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.

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 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 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


19

OTHER INVESTMENT STRATEGIES AND RISKS

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.

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.

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.

INVERSE FLOATING 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 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.

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 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 stated in the Annual Fund Operating Expenses tables, is reflected in the chart and is net of any fee waiver or expense reimbursement.

ORGANIZATION AND HISTORY

The Trust is a Massachusetts business trust organized in 1987. The Fund is an open-end, management investment company and is a non-diversified series of the Trust and represents the entire interest in a separate series of the Trust. The Fund is expected to commence investment operations as a series of the Trust on September 19, 2005.

The information provided for the Fund in this SAI for periods prior to the Fund Reorganization Date relates to the Predecessor Fund.

Effective October 13, 2003, the name of the Trust was changed from "Liberty-Stein Roe Funds Municipal Trust" to "Columbia Funds Trust IX." Effective September 19, 2005, the name of the Trust changed from "Columbia Funds Trust IX" to its current name.

The Fund offers four classes of shares - Class A, B, C and Z shares.

Except as indicated below under "Fundamental Investment Policies of the Funds," the Fund's investment policies are not fundamental and the Trustees may change the investment policies without shareholder approval.

FUNDAMENTAL INVESTMENT POLICIES OF THE FUND

The Investment Company Act of 1940 (the "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.

b


FUNDAMENTAL INVESTMENT POLICIES

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 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 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; and

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

c

management investment companies to the extent permitted by the Act, the rules and regulations thereunder, or any applicable exemptive relief.

8. In addition to the above fundamental investment restrictions, the Fund will: 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, the 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.

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 of income from other investments and distributions of any net realized capital gains will be taxable, whether paid in cash or reinvested in additional shares.

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. Likewise, 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 receipt of interest from California Tax-Exempt Bonds will cause corporations to recognize taxable income for purposes of both the federal and California Alternative Minimum Tax.

- 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.

The Fund pays a shareholders' servicing and transfer agency fee to CFS 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 CFS.

Investment personnel who manage the Fund attend IOC meetings from time to time to assist each IOC in its review of the Fund. Each IOC meets four times a year.

The following are members of the respective IOCs and the general categories of funds in the Fund Complex which they review:

IOC #1: Messrs. Lowry, Mayer and Neuhauser are responsible for reviewing funds in the following asset categories: Large Growth Diversified, Large Growth Concentrated, Small Growth, Outside Managed (i.e., sub-advised) and Municipal.

IOC #2: Mr. Hacker and Ms. Verville are responsible for reviewing funds in the following asset categories: Large Blend, Small Blend, Foreign Stock, Fixed Income - Multi Sector and Fixed Income - Core.

IOC #3: Messrs. Theobald and Stitzel and Ms. Kelly are responsible for reviewing funds in the following asset categories: Large Value, Mid Cap Value, Small Value, Asset Allocation, High Yield and Money Market.

IOC #4: Messrs. Nelson, Simpson and Woolworth are responsible for reviewing funds in the following asset categories: Large Blend, Mid Cap Growth, Small Growth, Asset Allocation, Specialty Equity, Taxable Fixed Income and Money Market.

COMPENSATION

As of the 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 benchmark and peer group 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 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 Class Z shares. Under the Plan, the Fund pays CMD monthly a service fee at an annual rate of 0.10% of the 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 Fund also pay CMD monthly a distribution fee at an annual rate of 0.75% of the Fund's average daily net assets attributed to the Fund's Class B and Class C shares. CMD has voluntarily agreed to waive a portion of the 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 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.

l

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 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 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 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. The CDSCs and initial sales charge are described in the Prospectus 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 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.

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

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 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.

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.

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.

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;

12

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 clearing corporation may not at all times be adequate to handle current trading volume; or (vi) one or more exchanges could, for

13

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

14

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

15

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.

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

18

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. 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

19

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. Treasury securities maturing on a quarterly basis through the conversion date, and a forward purchase contract with an existing

20

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, 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

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, 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.

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.

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.

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.

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 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).

36

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.

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.

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.

40

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 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 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

41

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.

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.

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.

43

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 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 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.

47

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.

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.

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:

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.

50

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.

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. 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.

51

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, 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.

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 schedul e 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

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 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.

56

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 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).

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.

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:

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.

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, 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.

63

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.

64

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);

65

(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.

66

- 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.

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.

67

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.

68

- 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.

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.

ITEM 24. PERSONS CONTROLLED BY OR UNDER COMMON CONTROL WITH THE REGISTRANT.

ITEM 25. INDEMNIFICATION.

Article Fifth of the Amended and Restated By-Laws of the Registrant (Exhibit
(b), which Article is incorporated herein by reference, provides that Registrant shall provide indemnification of its trustees and officers (including each person who serves or has served at Registrant's request as a director, officer, or trustee of another organization in which Registrant 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 may provide indemnification of its trustees and officers (including each person who serves or has served at Registrant's request as a director, officer, or trustee of another organization in which Registrant has any interest as a shareholder, creditor or otherwise) who are employees or officers of any investment adviser to the Trust 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 Second Amended and Restated Agreement and Declaration of Trust nor the Amended and Restated 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 Fifth 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 Fifth 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 Fifth 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 Fifth does not prevent the recovery from any Covered Person of any amount paid to such Covered Person in accordance with Article Fifth 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 Fifth also provides that its indemnification provisions are not exclusive.

Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to trustees, officers, and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by Registrant of expenses incurred or paid by a trustee, officer, or controlling person of Registrant in the successful defense of any action, suit, or proceeding) is asserted by such trustee, officer, or controlling person in connection with the securities being registered, Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question of whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

Registrant, its trustees and officers, Columbia Management Advisors, Inc. ("Columbia"), the other investment companies advised by Columbia, and persons affiliated with them are insured against certain expenses in connection with the defense of actions, suits, or proceedings, and certain liabilities that might be imposed as a result of such actions, suits, or proceedings. Registrant will not pay any portion of the premiums for coverage under such insurance that would (1) protect any trustee or officer 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 or (2) protect Columbia or principal underwriter, if any, against any liability to Registrant or its shareholders to which such person would otherwise be subject by reason of willful misfeasance, bad faith, or gross negligence, in the performance of its duties, or by reason of its reckless disregard of its duties and obligations under its contract or agreement with the Registrant; for this purpose the Registrant will rely on an allocation of premiums determined by the insurance company.

Pursuant to the indemnification agreement dated July 1, 1995, among the Registrant, its transfer agent and Columbia, Registrant, its trustees, officers and employees, its transfer agent and the transfer agent's directors, officers and employees are indemnified by Columbia against any and all losses, liabilities, damages, claims and expenses arising out of any act or omission of the Registrant or its transfer agent performed in conformity with a request of Columbia that the transfer agent and the Registrant deviate from their normal procedures in connection with the issue, redemption or transfer of shares for a client of Columbia.

Registrant, its trustees, officers and each person, if any, who controls the Registrant within the meaning of Section 15 of the Securities Act of 1933 are indemnified by the distributor of Registrant's shares (the "distributor"), pursuant to the terms of the distribution agreement, which governs the


distribution of Registrant's shares, 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 registrant, its officers, trustees 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 registrant, its officers, trustees, or such controlling person resulting from such claims or demands, shall arise out of or be based upon (i) any untrue, or alleged untrue, statement of a material fact contained in information furnished by the distributor or any affiliate thereof to the registrant or its counsel and used in the registrant'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 registrant or its counsel required to be stated in such information or necessary to make such information not misleading, (ii) any untrue statement of a material fact contained in any sales literature prepared by the distributor, or any omission to 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 registrant to the distributor for use therein),
(iii) any willful misfeasance, bad faith or gross negligence in the performance of the distributor's obligations and duties under the distribution agreement or by reason of its reckless disregard thereof, or (iv) any breach by the distributor of any provision of the distribution agreement.

THIS SECOND AMENDED AND RESTATED AGREEMENT AND DECLARATION OF TRUST made at Boston, Massachusetts, effective on August 10, 2005, by the Trustees hereunder and the holders of shares of beneficial interest issued hereunder and to be issued hereunder as hereinafter provided:

WITNESSETH that

WHEREAS, this Trust has been formed to carry on the business of an investment company; and

WHEREAS, the Trustees have agreed to manage all property coming into their hands as trustees of a Massachusetts voluntary association with transferable shares in accordance with the provisions hereinafter set forth;

NOW, THEREFORE, the Trustees hereby declare that they will hold all cash, securities and other assets, which they may from time to time acquire in any manner as Trustee hereunder, IN TRUST to manage and dispose of the same upon the following terms and conditions for the benefit of the holders from time to time of shares in this Trust as hereinafter set forth.

ARTICLE I

Name and Definitions

Section 1. This Trust shall be known as "Columbia Funds Trust IX" and the Trustees shall conduct the business of the Trust under that name or any other name as they may from time to time determine.

Section 2. Definitions. Whenever used herein, unless otherwise required by the context or specifically provided:

(a) "Trust" refers to the Massachusetts business trust established by this Agreement and Declaration of Trust, as amended from time to time;

(b) "Trustees" refers to the persons signatory hereto, so long as they continue in office in accordance with the terms of this Declaration of Trust, and all other persons who may from time to time be duly elected or appointed in accordance with Article IV hereof;

(c) "Shares" means the equal proportionate units of interest into which the beneficial interest in the Trust or in the Trust property belonging to any Series of the


Trust or in any class of Shares of the Trust (as the context may require) shall be divided from time to time;

(d) "Shareholder" means a record owner of Shares;

(e) "1940 Act" refers to the Investment Company Act of 1940 and the Rules and Regulations thereunder, all as amended from time to time;

(f) The terms "Commission" and "principal underwriter" shall have the meanings given them in the 1940 Act;

(g) "Declaration of Trust" or "Declaration" shall mean this Agreement and Declaration of Trust, as amended or restated from time to time;

(h) "Bylaws" shall mean the Bylaws of the Trust, as amended from time to time;

(i) "Series Company" refers to the form of registered open-end investment company described in Section 18(f)(2) of the 1940 Act or in any successor statutory provision;

(j) "Series" refers to Series of Shares established and designated under or in accordance with the provisions of Article III;

(k) "Multi-Class Series" refers to Series of Shares established and designated as Multi-Class Series under or in accordance with the provisions of Article III, Section 6; and

(l) The terms "class" and "class of Shares" refer to each class of Shares into which the Shares of any Multi-Class Series may from time to time be divided in accordance with the provisions of Article III.

ARTICLE II

Purpose of Trust

The purpose of the Trust is to engage in the business of a management investment company.

ARTICLE III

Shares

Section 1. Division of Beneficial Interest. The beneficial interest in the Trust shall at all times be divided into an unlimited number of Shares, without par value. Subject to the provisions of Section 6 of this Article III, each Share shall have voting

2

rights as provided in Article V hereof, and holders of the Shares of any Series or class shall be entitled to receive dividends, when and as declared with respect thereto in the manner provided in Article VI, Section 1 hereof. Except as otherwise provided in Section 6 of this Article III with respect to Shares of Multi-Class Series, no Share shall have any priority or preference over any other Share of the same Series with respect to dividends or distributions upon termination of the Trust or of such Series made pursuant to Article VIII,
Section 4 hereof. Except as otherwise provided in Section 6 of this Article III with respect to Shares of Multi-Class Series, all dividends and distributions shall be made ratably among all Shareholders of a particular Series from the assets belonging to such Series according to the number of Shares of such Series held of record by such Shareholders on the record date for any dividend or distribution or on the date of termination, as the case may be. Shareholders shall have no preemptive or other right to subscribe to any additional Shares or other securities issued by the Trust. The Trustees may from time to time divide or combine the Shares of any particular Series or class into a greater or lesser number of Shares of that Series or class without thereby changing the proportionate beneficial interest of the Shares of that Series or class in the assets belonging to that Series or attributable to that class or in any way affecting the rights of Shares of any other Series or class.

Section 2. Ownership of Shares. The ownership of Shares shall be recorded on the books of the Trust or a transfer or similar agent for the Trust, which books shall be maintained separately for the Shares of each Series and class. No certificates certifying the ownership of Shares shall be issued except as the Trustees may otherwise determine from time to time. The Trustees may make such rules as they consider appropriate for the transfer of Shares of each Series and class and similar matters. The record books of the Trust as kept by the Trust or any transfer or similar agent, as the case may be, shall be conclusive as to who are the Shareholders of each Series and class and as to the number of Shares of each Series and class held from time to time by each.

Section 3. Investments in the Trust. The Trustees shall accept investments in the Trust from such persons and on such terms and for such consideration as they from time to time authorize.

Section 4. Status of Shares and Limitation of Personal Liability. Shares shall be deemed to be personal property giving only the rights provided in this instrument. Every Shareholder by virtue of having become a Shareholder shall be held to have expressly assented and agreed to the terms hereof and to have become a party hereto. The death of a Shareholder during the continuance of the Trust shall not operate to terminate the same nor entitle the representative of any deceased Shareholder to an accounting or to take any action in court or elsewhere against the Trust or the Trustees, but entitles such representative only to the rights of said deceased Shareholder under this Trust. Ownership of Shares shall not entitle the Shareholder to any title in or to the whole or any part of the Trust property or right to call for a partition or division of the same or for an accounting, nor shall the ownership of Shares constitute the Shareholders partners. Neither the Trust nor the Trustees, nor any officer, employee or agent of the Trust, shall have any power to bind personally any Shareholder, nor except as specifically provided

3

herein to call upon any Shareholder for the payment of any sum of money or assessment whatsoever other than such as the Shareholder may at any time personally agree to pay.

Section 5. Power of Trustees to Change Provisions Relating to Shares. Notwithstanding any other provisions of this Declaration of Trust and without limiting the power of the Trustees to amend the Declaration of Trust as provided elsewhere herein, the Trustees shall have the power to amend this Declaration of Trust, at any time and from time to time, in such manner as the Trustees may determine in their sole discretion, without the need for Shareholder action, so as to add to, delete, replace or otherwise modify any provisions relating to the Shares contained in this Declaration of Trust for the purpose of (i) responding to or complying with any regulations, orders, rulings or interpretations of any governmental agency or any laws, now or hereafter applicable to the Trust, or
(ii) designating and establishing Series or classes in addition to those established in Section 6 of this Article III; provided that before adopting any such amendment without Shareholder approval the Trustees shall determine that it is consistent with the fair and equitable treatment of all Shareholders. The establishment and designation of any Series of Shares in addition to the Series established and designated in Section 6 of this Article III shall be effective upon either the execution by a majority of the then Trustees of an amendment to this Declaration of Trust, taking the form of a complete restatement or otherwise, or the adoption by vote or written consent of a majority of the then Trustees of a resolution setting forth such establishment and designation and the relative rights and preferences of such Series, or as otherwise provided in such amendment or resolution. The establishment and designation of any class of Shares shall be effective upon either the execution by a majority of the then Trustees of an amendment to this Declaration of Trust or the adoption by vote or written consent of a majority of the then Trustees of a resolution setting forth such establishment and designation and the relative rights and preferences of such class and such eligibility requirements for investment therein as the Trustees may determine, or as otherwise provided in such amendment or resolution.

Without limiting the generality of the foregoing, the Trustees may, without the approval of Shareholders, for the above-stated purposes, amend the Declaration of Trust to:

(a) create one or more Series or classes of Shares (in addition to any Series or classes already existing or otherwise) with such rights and preferences and such eligibility requirements for investment therein as the Trustees shall determine and reclassify any or all outstanding Shares as shares of particular Series or classes in accordance with such eligibility requirements;

(b) amend any of the provisions set forth in paragraphs (a) through (j) of
Section 6 of this Article III;

(c) combine one or more Series or classes of Shares into a single Series or class on such terms and conditions as the Trustees shall determine or consolidate, merge or transfer assets of the Trust or a Series as set forth in Article VIII, Section 5;

4

(d) change or eliminate any eligibility requirements for investment in Shares of any Series or class, including without limitation the power to provide for the issue of Shares of any Series or class in connection with any merger or consolidation of the Trust with another trust or company or any acquisition by the Trust of part or all of the assets of another trust or company;

(e) change the designation of any Series or class of Shares;

(f) change the method of allocating dividends among the various Series and classes of Shares;

(g) allocate any specific assets or liabilities of the Trust or any specific items of income or expense of the Trust to one or more Series or classes of Shares; and

(h) specifically allocate assets to any or all Series of Shares or create one or more additional Series of Shares which are preferred over all other Series of Shares in respect of assets specifically allocated thereto or any dividends paid by the Trust with respect to any net income, however determined, earned from the investment and reinvestment of any assets so allocated or otherwise and provide for any special voting or other rights with respect to such Series or any classes of Shares thereof.

Section 6. Establishment and Designation of Series and Classes.

Shares of each Series established in this Section 6 shall have the following rights and preferences relative to Shares of each other Series, and Shares of each class of a Multi-Class Series shall have such rights and preferences relative to other classes of the same Series as are set forth below, together with such other rights and preferences relative to such other classes as are set forth in any resolution of the Trustees establishing and designating such class of Shares:

(a) Assets belonging to Series. Subject to the provisions of paragraph (c) of this Section 6:

All consideration received by the Trust for the issue or sale of Shares of a particular Series, together with all assets in which such consideration is invested or reinvested, all income, earnings, profits and proceeds thereof from whatever source derived, including, without limitation, any proceeds derived from the sale, exchange or liquidation of such assets, and any funds or payments derived from any reinvestment of such proceeds in whatever form the same may be, shall irrevocably belong to that Series for all purposes, subject only to the rights of creditors of that Series, and shall be so recorded upon the books of account of the Trust. Such consideration, assets, income, earnings, profits and proceeds thereof, from whatever source derived, including, without limitation, any proceeds derived from the sale, exchange or liquidation of such assets, and any funds or payments derived from any reinvestment of such proceeds, in whatever form the same may be, are herein referred to as "assets belonging to" that Series. In the event

6

that there are any assets, income, earnings, profits and proceeds thereof, funds or payments which are not readily identifiable as belonging to any particular Series (collectively "General Assets"), the Trustees shall allocate such General Assets to, between or among any one or more of the Series established and designated from time to time in such manner and on such basis as they, in their sole discretion, deem fair and equitable, and any General Asset so allocated to a particular Series shall belong to that Series. Each such allocation by the Trustees shall be conclusive and binding upon the Shareholders of all Series for all purposes.

(b) Liabilities Belonging to Series. Subject to the provisions of paragraph
(c) of this Section 6:

The assets belonging to each particular Series shall be charged solely with the liabilities of the Trust in respect to that Series, the expenses, costs, charges and reserves attributable to that Series, and any general liabilities of the Trust which are not readily identifiable as belonging to any particular Series but which are allocated and charged by the Trustees to and among any one or more of the Series established and designated from time to time in a manner and on such basis as the Trustees in their sole discretion deem fair and equitable. The liabilities, expenses, costs, charges and reserves so charged to a Series are herein referred to as "liabilities belonging to" that Series. Each allocation of liabilities, expenses, costs, charges and reserves by the Trustees shall be conclusive and binding upon the Shareholders of all Series for all purposes.

(c) Apportionment of Assets etc. in Case of Multi-Class Series. In the case of any Multi-Class Series, to the extent necessary or appropriate to give effect to the relative rights and preferences of any classes of Shares of such Series,
(i) any assets, income, earnings, profits, proceeds, liabilities, expenses, charges, costs and reserves belonging or attributable to that Series may be allocated or attributed to a particular class of Shares of that Series or apportioned among two or more classes of Shares of that Series; and (ii) Shares of any class of such Series may have priority or preference over shares of other classes of such Series with respect to dividends or distributions upon termination of the Trust or of such Series or class or otherwise, provided that no Share shall have any priority or preference over any other Shares of the same class and that all dividends and distributions to Shareholders of a particular class shall be made ratably among all Shareholders of such class according to the number of Shares of such class held of record by such Shareholders on the record date for any dividend or distribution or on the date of termination, as the case may be.

(d) Dividends, Distributions, Redemptions and Repurchases. Notwithstanding any other provisions of this Declaration, including, without limitation, Article VI, no dividend or distribution (including, without limitation, any distribution paid upon termination of the Trust or of any Series or class) with respect to, nor any redemption or repurchase of, the Shares of any Series or class shall be effected by the Trust other than from the assets belonging to such Series or attributable to such class, nor shall any Shareholder of any particular Series or class otherwise have any right or claim against the assets belonging to any other Series or attributable to any other class except to

7

the extent that such Shareholder has such a right or claim hereunder as a Shareholder of such other Series or class.

(e) Voting. Notwithstanding any of the other provisions of this Declaration, including, without limitation, Section 1 of Article V, the Shareholders of any particular Series or class shall not be entitled to vote on any matters as to which such Series or class is not affected. On any matter submitted to a vote of Shareholders, all Shares of the Trust then entitled to vote shall, except as otherwise provided in the Bylaws, be voted in the aggregate as a single class without regard to Series or class of Shares, except that (1) when required by the 1940 Act or when the Trustees shall have determined that the matter affects one or more Series or classes of Shares materially differently, Shares shall be voted by individual Series or class and
(2) when the matter affects only the interests of one or more Series or classes, only Shareholders of such Series or classes shall be entitled to vote thereon. There shall be no cumulative voting in the election of Trustees.

(f) Equality. Except to the extent necessary or appropriate to give effect to the relative rights and preferences of any classes of Shares of a Multi-Class Series, all the Shares of each particular Series shall represent an equal proportionate interest in the assets belonging to that Series (subject to the liabilities belonging to that Series), and each Share of any particular Series shall be equal to each other Share of that Series. All the Shares of each particular class of Shares within a Multi-Class Series shall represent an equal proportionate interest in the assets belonging to such Series that are attributable to such class (subject to the liabilities attributable to such class), and each Share of any particular class within a Multi-Class Series shall be equal to each other Share of such class.

(g) Fractions. Any fractional Share of a Series or class shall carry proportionately all the rights and obligations of a whole Share of that Series or class, including rights with respect to voting, receipt of dividends and distributions, redemption of Shares and termination of the Trust.

(h) Exchange Privilege. The Trustees shall have the authority to provide that the holders of Shares of any Series or class shall have the right to exchange said Shares for Shares of one or more other Series or classes of Shares in accordance with such requirements and procedures as may be established by the Trustees.

(i) Combination of Series or Classes. Without limiting the authority of the Trustees set forth in Article VIII, Section 5, the Trustees shall have the authority, without the approval of the Shareholders of any Series or class unless otherwise required by applicable law, to combine the assets and liabilities belonging to any two or more Series or attributable to any class into assets and liabilities belonging to a single Series or attributable to a single class.

(j) Elimination of Series or Class. At any time that there are no Shares outstanding of any particular Series previously established and designated, the Trustees may abolish and rescind the establishment and designation of that Series, either by

8

amending this Declaration of Trust in the manner provided in Section 5 of this Article III for the establishment and designation of Series (if such Series was established and designated by an amendment to this Declaration of Trust), or by vote or written consent of a majority of the then Trustees (if such Series was established and designated by Trustee vote or written consent). At any time that there are no Shares outstanding of any particular class previously established and designated of a Multi- Class Series, the Trustees may abolish that class and rescind the establishment and designation thereof, either by amending this Declaration of Trust in the manner provided in Section 5 of this Article III for the establishment and designation of classes (if such class was established and designated by an amendment to this Declaration of Trust), or by vote or written consent of a majority of the then Trustees (if such class was established and designated by Trustee vote or written consent).

Section 7. Indemnification of Shareholders. In case any Shareholder or former Shareholder shall be held to be personally liable solely by reason of his or her being or having been a Shareholder of the Trust or of a particular Series or class and not because of his or her acts or omissions or for some other reason, the Shareholder or former Shareholder (or his or her heirs, executors, administrators or other legal representatives or, in the case of a corporation or other entity, its corporate or other general successor) shall be entitled out of the assets of the Series (or attributable to the class) of which he or she is a Shareholder or former Shareholder to be held harmless from and indemnified against all loss and expense arising from such liability.

Section 8. No Preemptive Rights. Shareholders shall have no preemptive or other right to subscribe to any additional Shares or other securities issued by the Trust.

Section 9. Derivative Claims. No Shareholder shall have the right to bring or maintain any court action, proceeding or claim on behalf of the Trust or any Series without first making demand on the Trustees requesting the Trustees to bring or maintain such action, proceeding or claim. Such demand shall be excused only when the plaintiff makes a specific showing that irreparable injury to the Trust or Series would otherwise result. Such demand shall be mailed to the Secretary of the Trust at the Trust's principal office and shall set forth in reasonable detail the nature of the proposed court action, proceeding or claim and the essential facts relied upon by the Shareholder to support the allegations made in the demand. The Trustees shall consider such demand within 45 days of its receipt by the Trust. In their sole discretion, the Trustees may submit the matter to a vote of Shareholders of the Trust or Series, as appropriate. Any decision by the Trustees to bring, maintain or settle (or not to bring, maintain or settle) such court action, proceeding or claim, or to submit the matter to a vote of Shareholders, shall be made by the Trustees in their business judgment and shall be binding upon the Shareholders.

9

ARTICLE IV

The Trustees

Section 1. Election and Tenure. The Trustees may fix the number of Trustees, fill vacancies in the Trustees, including vacancies arising from an increase in the number of Trustees, or remove Trustees with or without cause. Each Trustee shall serve during the continued lifetime of the Trust until he or she dies, resigns or is removed, or, if sooner, until the next meeting of Shareholders called for the purpose of electing Trustees and until the election and qualification of his or her successor. Any Trustee may resign at any time by written instrument signed by him or her and delivered to any officer of the Trust or to a meeting of the Trustees. Such resignation shall be effective upon receipt unless specified to be effective at some other time. Except to the extent expressly provided in a written agreement with the Trust, no Trustee resigning and no Trustee removed shall have any right to any compensation for any period following his or her resignation or removal, or any right to damages on account of such removal. The Shareholders may fix the number of Trustees and elect Trustees at any meeting of Shareholders called by the Trustees for that purpose and to the extent required by applicable law, including paragraphs (a) and (b) of Section 16 of the 1940 Act.

Section 2. Effect of Death, Resignation, etc. of a Trustee. The death, declination, resignation, retirement, removal or incapacity of the Trustees, or any of them, shall not operate to annul the Trust or to revoke any existing agency created pursuant to the terms of this Declaration of Trust.

Section 3. Powers. Subject to the provisions of this Declaration of Trust, the business of the Trust shall be managed by the Trustees, and they shall have all powers necessary or convenient to carry out that responsibility including the power to engage in securities transactions of all kinds on behalf of the Trust. Without limiting the foregoing, the Trustees may adopt Bylaws not inconsistent with this Declaration of Trust providing for the regulation and management of the affairs of the Trust and may amend and repeal them to the extent that such Bylaws do not reserve that right to the Shareholders; they may elect and remove such officers and appoint and terminate such agents as they consider appropriate; they may appoint from their own number and terminate one or more committees consisting of one or more Trustees which may exercise the powers and authority of the Trustees to the extent that the Trustees determine; they may employ one or more custodians of the assets of the Trust and may authorize such custodians to employ sub-custodians and to deposit all or any part of such assets in a system or systems for the central handling of securities or with a Federal Reserve Bank, retain a transfer agent or a shareholder servicing agent, or both, provide for the distribution of Shares by the Trust, through one or more principal underwriters or otherwise, set record dates for the determination of Shareholders with respect to various matters, and in general delegate such authority as they consider desirable to any officer of the Trust, to any committee of the Trustees and to any agent or employee of the Trust or to any such custodian or underwriter.

10

Without limiting the foregoing, the Trustees shall have power and authority:

(a) To invest and reinvest cash, and to hold cash uninvested;

(b) To sell, exchange, lend, pledge, mortgage, hypothecate, lease, write options with respect to or otherwise deal in any property rights relating to any or all of the assets of the Trust;

(c) To vote or give assent, or exercise any rights of ownership, with respect to stock or other securities or property; and to execute and deliver proxies or powers of attorney to such person or persons as the Trustees shall deem proper, granting to such person or persons such power and discretion with relation to securities or property as the Trustees shall deem proper;

(d) To exercise powers and rights of subscription or otherwise which in any manner arise out of ownership of securities;

(e) To hold any security or property in a form not indicating any trust, whether in bearer, unregistered or other negotiable form, or in its own name or in the name of a custodian or sub-custodian or a nominee or nominees or otherwise;

(f) To consent to or participate in any plan for the reorganization, consolidation or merger of any corporation or issuer of any security which is held in the Trust; to consent to any contract, lease, mortgage, purchase or sale of property by such corporation or issuer; and to pay calls or subscriptions with respect to any security held in the Trust;

(g) To join with other security holders in acting through a committee, depositary, voting trustee or otherwise, and in that connection to deposit any security with, or transfer any security to, any such committee, depositary or trustee, and to delegate to them such power and authority with relation to any security (whether or not so deposited or transferred) as the Trustees shall deem proper, and to agree to pay, and to pay, such portion of the expenses and compensation of such committee, depositary or trustee as the Trustees shall deem proper;

(h) To compromise, arbitrate or otherwise adjust claims in favor of or against the Trust or any matter in controversy, including but not limited to claims for taxes;

(i) To enter into joint ventures, general or limited partnerships and any other combinations or associations;

(j) To borrow funds or other property;

(k) To endorse or guarantee the payment of any notes or other obligations of any person; and to make contracts of guaranty or suretyship, or otherwise assume liability for payment of such notes or other obligations;

(l) To purchase and pay for entirely out of Trust property such insurance as they may deem necessary or appropriate for the conduct of the business of the Trust,

11

including, without limitation, insurance policies insuring the assets of the Trust and payment of distributions and principal on its portfolio investments, and insurance policies insuring the Shareholders, Trustees, officers, employees, agents, investment advisers, principal underwriters or independent contractors of the Trust individually against all claims and liabilities of every nature arising by reason of holding, being or having held any such office or position, or by reason of any action alleged to have been taken or omitted by any such person as Trustee, officer, employee, agent, investment adviser, principal underwriter or independent contractor, including any action taken or omitted that may be determined to constitute negligence, whether or not the Trust would have the power to indemnify such person against liability; and

(m) To pay pensions as deemed appropriate by the Trustees and to adopt, establish and carry out pension, profit-sharing, share bonus, share purchase, savings, thrift and other retirement, incentive and benefit plans, trusts and provisions, including the purchasing of life insurance and annuity contracts as a means of providing such retirement and other benefits, for any or all of the Trustees, officers, employees and agents of the Trust.

The Trustees shall not in any way be bound or limited by any present or future law or custom in regard to investments by Trustees. The Trustees shall not be required to obtain any court order to deal with any assets of the Trust or take any other action hereunder.

Section 4. Payment of Expenses by the Trust. The Trustees are authorized to pay or cause to be paid out of the principal or income of the Trust, or partly out of principal and partly out of income, as they deem fair, all expenses, fees, charges, taxes and liabilities incurred or arising in connection with the Trust, or in connection with the management thereof, including but not limited to, the Trustees' compensation and such expenses and charges for the services of the Trust's officers, employees, administrators, investment advisers or managers, principal underwriter, auditor, counsel, custodian, transfer agent, shareholder servicing agent, and such other agents or independent contractors, and such other expenses and charges, as the Trustees may deem necessary or proper to incur.

Section 5. Payment of Expenses by Shareholders. The Trustees shall have the power, as frequently as they may determine, to cause each Shareholder, or each Shareholder of any particular Series or class, to pay directly, in advance or arrears, for charges of the Trust's custodian or transfer, shareholder servicing or similar agent, an amount fixed from time to time by the Trustees, by setting off such charges due from such Shareholder from declared but unpaid dividends owed such Shareholder and/or by reducing the number of Shares in the account of such Shareholder by that number of full and/or fractional Shares which represents the outstanding amount of such charges due from such Shareholder.

Section 6. Ownership of Assets of the Trust. Title to all of the assets of the Trust shall at all times be considered as vested in the Trustees.

Section 7. Advisory, Management and Distribution Contracts. Subject to such requirements and restrictions as may be set forth in the Bylaws, the Trustees may, at any time and from time to time, contract for exclusive or nonexclusive advisory and/or management services for the Trust or for any Series or class with any corporation, trust, association or other organization (a "Manager"); and any such contract may contain such other terms as the Trustees may determine, including without limitation, authority for a Manager to determine from time to time without prior consultation with the Trustees what investments shall be purchased, held, sold or exchanged and what portion, if any, of the assets of the Trust shall be held uninvested and to make changes in the Trust's investments. The Trustees may also, at any time and from time to time, contract with a Manager or any other corporation, trust, association or other organization, appointing it exclusive or nonexclusive distributor or principal underwriter for the Shares, every such contract to comply with such requirements and restrictions as may be set forth in the Bylaws; and any such contract may contain such other terms as the Trustees may determine.

The fact that:

(i) any of the Shareholders, Trustees or officers of the Trust is a shareholder, director, officer, partner, trustee, employee, manager, adviser, principal underwriter, distributor or affiliate or agent of or for any corporation, trust, association or other organization, or of or for any parent or affiliate of any organization, with which an advisory or management contract, or principal underwriter's or distributor's contract or transfer, shareholder servicing or other agency contract may have been or may hereafter be made, or that any such organization, or any parent or affiliate thereof, is a Shareholder or has an interest in the Trust, or that

(ii) any corporation, trust, association or other organization with which an advisory or management contract or principal underwriter's or distributor's contract, or transfer, shareholder servicing or other agency contract may have been or may hereafter be made also has an advisory or management contract, or principal underwriter's or distributor's contract or transfer, shareholder servicing or other agency contract with one or more other corporations, trusts, associations or other organizations, or has other business or interests

shall not affect the validity of any such contract or disqualify any Shareholder, Trustee or officer of the Trust from voting upon or executing the same or create any liability or accountability to the Trust or its Shareholders.

ARTICLE V

Shareholders' Voting Powers and Meetings

Section 1. Voting Powers. The Shareholders shall have power to vote only
(i) for the election of Trustees as provided in Article IV, Section 1, (ii) to the extent provided in Article III, Section 9 as to whether or not a court action, proceeding or claim should or

13

should not be brought or maintained derivatively or as a class action on behalf of the Trust or the Shareholders, (iii) with respect to the termination of the Trust or any Series or class to the extent and as provided in Article VIII,
Section 4 and (iv) with respect to such additional matters relating to the Trust as may be required by applicable law, including the 1940 Act, this Declaration of Trust, the Bylaws or any registration of the Trust with the Commission (or any successor agency) or any state, or as the Trustees may consider necessary or desirable. The number of votes that each whole or fractional Share shall be entitled to vote as to any matter on which it is entitled to vote shall be as specified in the Bylaws. There shall be no cumulative voting in the election of Trustees. Shares may be voted in person or by proxy. A proxy with respect to Shares held in the name of two or more persons shall be valid if executed by any one of them unless at or prior to exercise of the proxy the Trust receives a specific written notice to the contrary from any one of them. A proxy purporting to be executed by or on behalf of a Shareholder shall be deemed valid unless challenged at or prior to its exercise and the burden of proving invalidity shall rest on the challenger. At any time when no Shares of a Series or class are outstanding the Trustees may exercise all rights of Shareholders of that Series or class with respect to matters affecting that Series or class and may with respect to that Series or class take any action required by law, this Declaration of Trust or the Bylaws to be taken by the Shareholders thereof.

Section 2. Voting Power and Meetings. Meetings of the Shareholders may be called by the Trustees for the purpose of electing Trustees as provided in Article IV, Section 1 and for such other purposes as may be prescribed by law, by this Declaration of Trust or by the Bylaws. Meetings of the Shareholders may also be called by the Trustees from time to time for the purpose of taking action upon any other matter deemed by the Trustees to be necessary or desirable. A meeting of Shareholders may be held at any place designated by the Trustees. Notice of any meeting of Shareholders, stating the time and place of the meeting, shall be given or caused to be given by the Trustees to each Shareholder by mailing such notice, postage prepaid, at least seven days before such meeting, at the Shareholder's address as it appears on the records of the Trust, or by facsimile or other electronic transmission, at least seven days before such meeting, to the telephone or facsimile number or e-mail or other electronic address most recently furnished to the Trust (or its agent) by the Shareholder. Whenever notice of a meeting is required to be given to a Shareholder under this Declaration of Trust or the Bylaws, a written waiver thereof, executed before or after the meeting by such Shareholder or his attorney thereunto authorized and filed with the records of the meeting, shall be deemed equivalent to such notice.

Section 3. Quorum and Required Vote. Except when a larger quorum is required by law, by the Bylaws or by this Declaration of Trust, 30% of the votes entitled to be cast shall constitute a quorum at a Shareholders' meeting. When any one or more Series or classes is to vote as a single class separate from any other Shares which are to vote on the same matters as a separate class or classes, 30% of the votes entitled to be cast by each such class entitled to vote shall constitute a quorum at a Shareholders' meeting of that class. Any meeting of Shareholders may be adjourned from time to time by a majority of the votes properly cast upon the question, whether or not a quorum is present, and the meeting may be held as adjourned within a reasonable time after the date set for the

14

original meeting without further notice. When a quorum is present at any meeting, a majority of the Shares voted shall decide any questions and a plurality shall elect a Trustee, except when a larger vote is required by any provision of this Declaration of Trust or the Bylaws or by law. If any question on which the Shareholders are entitled to vote would adversely affect the rights of any Series or class of Shares, the vote of a majority (or such larger vote as is required as aforesaid) of the Shares of such Series or class which are entitled to vote, voting separately, shall also be required to decide such question.

Section 4. Action by Written Consent. Any action taken by Shareholders may be taken without a meeting if Shareholders holding a majority of the Shares entitled to vote on the matter (or such larger proportion thereof as shall be required by any express provision of this Declaration of Trust or by the Bylaws) and holding a majority (or such larger proportion as aforesaid) of the Shares of any Series or class entitled to vote separately on the matter consent to the action in writing and such written consents are filed with the records of the meetings of Shareholders. Such consent shall be treated for all purposes as a vote taken at a meeting of Shareholders.

Section 5. Record Dates. For the purpose of determining the Shareholders of any Series or class who are entitled to vote or act at any meeting or any adjournment thereof, the Trustees may from time to time fix a time, which shall be not more than 90 days before the date of any meeting of Shareholders, as the record date for determining the Shareholders of such Series or class having the right to notice of and to vote at such meeting and any adjournment thereof, and in such case only Shareholders of record on such record date shall have such right, notwithstanding any transfer of Shares on the books of the Trust after the record date. For the purpose of determining the Shareholders of any Series or class who are entitled to receive payment of any dividend or of any other distribution, the Trustees may from time to time fix a date, which shall be on or before the date for the payment of such dividend or such other payment, as the record date for determining the Shareholders of such Series or class having the right to receive such dividend or distribution. Without fixing a record date the Trustees may for voting and/or distribution purposes close the register or transfer books for one or more Series or classes for all or any part of the period prior to a meeting of Shareholders or the payment of a distribution. Nothing in this Section shall be construed as precluding the Trustees from setting different record dates for different Series or classes.

Section 6. Additional Provisions. The Bylaws may include further provisions for Shareholders' votes and meetings and related matters.

ARTICLE VI

Net Income, Distributions, and Redemptions and Repurchases

Section 1. Distributions of Net Income. The Trustees shall each year, or more frequently if they so determine in their sole discretion, distribute to the Shareholders of each Series, in Shares of that Series, cash or otherwise, an amount approximately equal to

15

the net income attributable to the assets belonging to such Series and may from time to time distribute to the Shareholders of each Series, in Shares of that Series, cash or otherwise, such additional amounts, but only from the assets belonging to such Series, as they may authorize. Except as otherwise permitted by paragraph (c) of Section 6 of Article III in the case of Multi-Class Series, all dividends and distributions on Shares of a particular Series shall be distributed pro rata to the holders of that Series in proportion to the number of Shares of that Series held by such holders and recorded on the books of the Trust at the date and time of record established for the payment of such dividend or distributions.

The manner of determining net income, income, asset values, capital gains, expenses, liabilities and reserves of any Series or class may from time to time be altered as necessary or desirable in the judgment of the Trustees to conform such manner of determination to any other method prescribed or permitted by applicable law. Net income shall be determined by the Trustees or by such person as they may authorize at the times and in the manner provided in the Bylaws. Determinations of net income of any Series or class and determinations of income, asset value, capital gains, expenses and liabilities made by the Trustees, or by such person as they may authorize, in good faith, shall be binding on all parties concerned. The foregoing sentence shall not be construed to protect any Trustee, officer or agent of the Trust against any liability to the Trust or its security holders to which he or she 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.

If, for any reason, the net income of any Series or class determined at any time is a negative amount, the pro rata share of such negative amount allocable to each Shareholder of such Series or class shall constitute a liability of such Shareholder to that Series or class which shall be paid out of such Shareholder's account at such times and in such manner as the Trustees may from time to time determine (x) out of the accrued dividend account of such Shareholder, (y) by reducing the number of Shares of that Series or class in the account of such Shareholder or (z) otherwise.

Section 2. Redemptions and Repurchases. The Trust shall purchase such Shares as are offered by any Shareholder for redemption, upon the presentation of a proper instrument of transfer together with a request directed to the Trust or a person designated by the Trust that the Trust purchase such Shares or in accordance with such other procedures for redemption as the Trustees may from time to time authorize; and the Trust will pay therefor the net asset value thereof, as determined in accordance with the Bylaws, next determined. Payment for said Shares shall be made by the Trust to the Shareholder within seven days after the date on which the request is made. The obligation set forth in this
Section 2 is subject to the provision that in the event that any time the New York Stock Exchange is closed for other than weekends or holidays, or if permitted by the rules of the Commission during periods when trading on the New York Stock Exchange is restricted or during any emergency which makes it impracticable for the Trust to dispose of the investments of the applicable Series or to determine fairly the value of the net assets belonging to such Series or attributable to any class thereof or during any other period permitted by order of the Commission for the protection of

16

investors, such obligations may be suspended or postponed by the Trustees. The Trust may also purchase or repurchase Shares at a price not exceeding the net asset value of such Shares in effect when the purchase or repurchase or any contract to purchase or repurchase is made.

The redemption price may in any case or cases be paid wholly or partly in kind if the Trustees determine that such payment is advisable in the interest of the remaining Shareholders of the Series the Shares of which are being redeemed. The fair value, selection and quantity of any securities or other property so paid or delivered as all or part of the redemption price may be determined by or under authority of the Trustees. In no case shall the Trust be liable for any delay of any corporation or other person in transferring securities selected for delivery as all or part of any payment in kind.

Section 3. Redemptions at the Option of the Trust. The Trust shall have the right at its option and at any time to redeem Shares of any Shareholder at the net asset value thereof: (i) if at such time such Shareholder owns Shares of any Series or class having an aggregate net asset value of less than an amount determined from time to time by the Trustees; or (ii) to the extent that such Shareholder owns Shares equal to or in excess of a percentage determined from time to time by the Trustees of the outstanding Shares of the Trust or of any Series or class.

ARTICLE VII

Compensation and Limitation of Liability of Trustees

Section 1. Compensation. The Trustees as such shall be entitled to reasonable compensation from the Trust; they may fix the amount of their compensation. Nothing herein shall in any way prevent the employment of any Trustee for advisory, management, legal, accounting, investment banking or other services and payment for the same by the Trust.

Section 2. Limitation of Liability. No Trustee, officer, employee or agent of the Trust shall be subject to any liability whatsoever to any person in connection with Trust property or the affairs of the Trust, and no Trustee shall be responsible or liable in any event for any neglect or wrong-doing of any officer, agent, employee, Manager or principal underwriter of the Trust or for the act or omission of any other Trustee. For the sake of clarification and without limiting the foregoing, the appointment, designation or identification of a Trustee as the chairman of the Board, the lead or assistant lead independent Trustee, a member or chairman of a committee of the Board, an expert on any topic or in any area (including an audit committee financial expert) or as having any other special appointment, designation or identification shall not
(a) impose on that person any duty, obligation or liability that is greater than the duties, obligations and liabilities imposed on that person as a Trustee in the absence of the appointment, designation or identification or (b) affect in any way such Trustee's rights or entitlement to indemnification, and no Trustee who has special skills or expertise, or is appointed, designated or identified as aforesaid, shall (x) be held to a higher standard of care by virtue thereof or (y) be limited with respect to any indemnification to which such Trustee

17

would otherwise be entitled. Nothing in this Declaration of Trust, including without limitation anything in this Article VII, Section 2, shall protect any Trustee, officer, employee or agent of the Trust against any liabilities to the Trust or its Shareholders to which he, she or it 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, her or its office or position with or on behalf of the Trust.

Every note, bond, contract, instrument, certificate or undertaking and every other act or thing whatsoever issued, executed or done by or on behalf of the Trust or the Trustees or any of them in connection with the Trust shall be conclusively deemed to have been issued, executed or done only in or with respect to their or his or her capacity as Trustees or Trustee, and such Trustees or Trustee shall not be personally liable thereon.

ARTICLE VIII

Miscellaneous

Section 1. Trustees, Shareholders, etc. Not Personally Liable; Notice. All persons extending credit to, contracting with or having any claim against the Trust or any Series or class shall look only to the assets of the Trust, or, to the extent that the liability of the Trust may have been expressly limited by contract to the assets of a particular Series or attributable to a particular class, only to the assets belonging to the relevant Series or attributable to the relevant class, for payment under such credit, contract or claim; and neither the Shareholders nor the Trustees, nor any of the Trust's officers, employees or agents, whether past, present or future, shall be personally liable therefor. Nothing in this Declaration of Trust shall protect any Trustee against any liability to which such Trustee would otherwise be subject by reason of willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of the office of Trustee.

Every note, bond, contract, instrument, certificate or undertaking made or issued on behalf of the Trust by the Trustees, by any officer or officers or otherwise shall give notice that this Declaration of Trust is on file with the Secretary of the Commonwealth of Massachusetts and shall recite that the same was executed or made by or on behalf of the Trust or by them as Trustee or Trustees or as officer or officers or otherwise and not individually and that the obligations of such instrument are not binding upon any of them or the Shareholders individually but are binding only upon the assets and property of the Trust or upon the assets belonging to the Series or attributable to the class for the benefit of which the Trustees have caused the note, bond, contract, instrument, certificate or undertaking to be made or issued, and may contain such further recital as he or she or they may deem appropriate, but the omission of any such recital shall not operate to bind any Trustee or Trustees or officer or officers or Shareholders or any other person individually.

Section 2. Trustee's Good Faith Action, Expert Advice, No Bond or Surety. The exercise by the Trustees of their powers and discretions hereunder shall be binding upon

18

everyone interested. A Trustee shall be liable for his or her own willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of the office of Trustee, and for nothing else, and shall not be liable for errors of judgment or mistakes of fact or law. The Trustees may take advice of counsel or other experts with respect to the meaning and operation of this Declaration of Trust, and shall be under no liability for any act or omission in accordance with such advice or for failing to follow such advice. The Trustees shall not be required to give any bond as such, nor any surety if a bond is required.

Section 3. Liability of Third Persons Dealing with Trustees. No person dealing with the Trustees shall be bound to make any inquiry concerning the validity of any transaction made or to be made by the Trustees or to see to the application of any payments made or property transferred to the Trust or upon its order.

Section 4. Termination of Trust, Series or Class. Unless terminated as provided herein, the Trust shall continue without limitation of time.

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 may 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 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 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

-4-

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 adjudicated by a court of competent jurisdiction to have been liable to the Trust or its

-5-

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. Except as the Trustees may generally or in particular cases authorize the execution thereof in some other manner, all checks, notes, drafts and other obligations and all registration statements and amendments thereto and all applications and amendments thereto to the Securities and Exchange Commission shall be signed by the Chairman of the Board, if any, the President, any Vice President, the Treasurer, any Assistant Treasurer, the Secretary, any Assistant Secretary or any of such other officers or agents as shall be designated for that purpose by a vote of the Trustees.

-6-

ARTICLE 9

PROVISIONS RELATING TO THE
CONDUCT OF THE TRUST'S BUSINESS

9.1 Determination of Net Income and Net Asset Value Per Share. The Trustees or any officer or officers or agent or agents of the Trust designated from time to time for this purpose by the Trustees shall determine at least once daily the net income and the value of all the assets attributable to any class or series of shares of the Trust on each day on which the New York Stock Exchange is open for unrestricted trading and at such other times as the Trustees shall designate. The net income and net asset value per share of each class and each series of shares of the Trust shall be determined in accordance with the Investment Company Act of 1940 and the rules and regulations thereunder and any related procedures and/or policies of the Trust, or an officer or officers or agent or agents, as aforesaid, as adopted or authorized by the Trustees from time to time.

9.2 Voting Power. Each whole share (or fractional share) outstanding on the record date 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 U. S. 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).

ARTICLE 10

AMENDMENTS TO THE BYLAWS

10.1 General. These Bylaws may be amended or repealed, in whole or in part, by a majority of the Trustees then in office at any meeting of the Trustees, or by written consent in lieu thereof.

ARTICLE 11

MISCELLANEOUS

11.1 Proxy Instructions Transmitted by Telephonic or Electronic Means. The placing of a Shareholder's name on a proxy pursuant to telephonic or electronically transmitted instructions obtained pursuant to procedures reasonably designed to verify that such instructions have been authorized by such Shareholder shall constitute execution of such proxy by or on behalf of such Shareholder.

COLUMBIA INTERNATIONAL STOCK FUND

MANAGEMENT AGREEMENT

AGREEMENT dated as of September 15, 2005, between COLUMBIA FUNDS TRUST IX, a Massachusetts business trust ("Trust"), with respect to COLUMBIA INTERNATIONAL STOCK FUND ("Fund"), and COLUMBIA MANAGEMENT ADVISORS, INC., an Oregon corporation ("Advisor").

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.

2. ALLOCATION OF CHARGES AND EXPENSES.

(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

1

shall promptly reimburse the Adviser for the costs, charges and expenses.

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, each calendar month the Fund shall pay to the Adviser a fee calculated at an annual rate as a percentage of daily net assets that declines as net assets increase as follows: 0.87% of the first $500 million of the average daily net assets of the Fund, 0.82% of the next $500 million, 0.77% of the next $500 million, 0.72% of the next $1.5 billion, 0.70% of the next $3 billion and 0.68% in excess of $6 billion.. 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. The Adviser covenants that it and its employees will comply with investment restrictions of the Fund's Bylaws applicable to them. 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.

(c) This Agreement shall automatically terminate if it is assigned. The Adviser shall notify the Fund of any change in the officers or directors of the Adviser within a reasonable time after the change. The terms "assignment," "vote of a majority of the outstanding voting securities", and "interested persons" shall have the meanings specified in the Act.

IN WITNESS WHEREOF the parties have caused this Agreement to be executed as of the day and year first written above.

SUB-ADVISORY AGREEMENT

SUB-ADVISORY AGREEMENT, dated this 15th day of September, 2005, by and between COLUMBIA MANAGEMENT ADVISORS, INC., an Oregon corporation (the "Adviser") and STEIN ROE INVESTMENT COUNSEL LLC, a Delaware limited liability company (the "Sub-Adviser").

WITNESSETH:

WHEREAS, the Adviser provides Columbia Tax-Managed Growth Fund (the "Fund"), a series of Columbia Funds Trust IX (the "Trust"), an open-end investment company registered under the Investment Company Act of 1940, as amended (the "1940 Act"), business services pursuant to the terms and conditions of an investment advisory agreement dated September 15, 2005 (the "Agreement") between the Adviser and the Trust, on behalf of the Fund; and

WHEREAS, the Sub-Adviser is willing to provide services to the Adviser on the terms and conditions hereinafter set forth.

NOW, THEREFORE, in consideration of the mutual covenants and agreements of the parties hereto as herein set forth, the parties covenant and agree as follows:

1. Duties of the Sub-Adviser. Subject to the supervision of the Trustees of the Trust and the Adviser, the Sub-Adviser will: (a) manage the investment of the assets of the Fund in accordance with the Fund's investment objectives, policies and limitations as stated in the Fund's then current Prospectus (the "Prospectus") and Statement of Additional Information (the "Statement") as provided by the Adviser to the Sub-Adviser and in compliance with the 1940 Act and the rules, regulations and orders thereunder; (b) place purchase and sale orders for portfolio transactions for the Fund; (c) evaluate such economic, statistical and financial information and undertake such investment research as it shall believe advisable; (d) employ professional portfolio managers to provide research services to the Fund; and (e) report results to the Board of Trustees of the Trust. The Adviser agrees to provide the Sub-Adviser with such assistance as may be reasonably requested by the Sub-Adviser in connection with its activities under this Agreement, including, without limitation, information concerning the Fund, its funds available, or to become available, for investment and generally as to the conditions of the Fund's affairs.

Should the Trustees of the Trust or the Adviser at any time make any determination as to investment policy and notify the Sub-Adviser thereof in writing, the Sub-Adviser shall be bound by such determination for the period, if any, specified in such notice or until notified that such determination has been revoked. Further, the Adviser or the Trustees of the Trust may at any time, upon written notice to the Sub-Adviser, suspend or restrict the right of the Sub-Adviser to determine what assets of the Fund shall be purchased or sold and what portion, if any, of the Fund's assets shall be held uninvested. It is understood that the Adviser undertakes to discuss with the Sub-Adviser any such determinations of investment policy and any such suspension or restrictions on the right of the Sub-Adviser to determine what assets of the Fund shall be purchased or sold or held uninvested, prior to the implementation thereof.

1

2. Certain Information to the Sub-Adviser. Copies of the Prospectus, the Statement, and the Trust's Declaration of Trust have been or will be delivered to the Sub-Adviser. The Adviser agrees to notify the Sub-Adviser of each change in the investment policies of the Fund and to provide to the Sub-Adviser as promptly as practicable copies of all amendments and supplements to the Prospectus, the Statement, and the Trust's Declaration of Trust. In addition, the Adviser will promptly provide the Sub-Adviser with any procedures applicable to the Sub-Adviser adopted from time to time by the Trustees of the Trust and agrees to provide promptly to the Sub-Adviser copies of all amendments thereto. The Sub-Adviser will be entitled to rely on all documents furnished to it by the Adviser.

3. Execution of Certain Documents. Subject to any other written instructions of the Adviser and the Trustees of the Trust, the Sub-Adviser is hereby appointed the Adviser's and the Trust's agent and attorney-in-fact to execute account documentation, agreements, contracts and other documents as the Sub-Adviser shall be requested to execute by brokers, dealers, counterparties and other persons in connection with its management of the assets of the Fund.

4. Reports. The Sub-Adviser shall furnish to the Trustees of the Trust or the Adviser, or both, as may be appropriate, quarterly reports of its activities on behalf of the Fund, as required by applicable law or as otherwise reasonably requested from time to time by the Trustees of the Trust or the Adviser, and such additional information, reports, evaluations, analyses and opinions as the Trustees of the Trust or the Adviser, as appropriate, may reasonably request from time to time.

5. Compensation of the Sub-Adviser. For the services to be rendered by the Sub-Adviser under this Agreement, the Adviser shall pay to the Sub-Adviser a monthly fee, payable within 10 business days after the last day of each month, composed of a basic fee and a performance adjustment. The basic fee shall be calculated at the end of each month by applying one-twelfth of the basic fee rate (0.20%) to the average of the net assets of the Fund (computed in the manner set forth in the Prospectus or Statement) determined as of the close of business on each business day throughout the month. The performance adjustment shall be determined by multiplying the basic fee by the performance adjustment rates set forth below. The resulting calculation is the total monthly fee paid by the Adviser to the Sub-Adviser. The performance adjustment rate shall be readjusted at the end of each calendar quarter based on the Fund's ranking in Morningstar, Inc.'s Large Blend category for domestic equity funds. The rates applicable to each ranking are as follows:

MORNINGSTAR RANKING   PERFORMANCE ADJUSTMENT RATE
-------------------   ---------------------------
     Quartile 1                   1.25
     Quartile 2                   1.00
    Below Median                  0.75

The performance adjustment rate shall be the rate applicable to the Fund's Morningstar ranking for the three-year period ending on the last day of the prior calendar quarter. In the event this Agreement is terminated during any month, the basic fee rate and performance adjustment rate shall be applied to net assets averaged over that month ending on the last business day on

2

which this Agreement is in effect. Notwithstanding the above, the annual compensation payable to the Sub-Adviser under this Agreement shall not be less than $350,000. If the compensation paid to the Sub-Adviser under this Agreement for any calendar year is less than $350,000, the Adviser, as soon as practicable after the end of the year, shall pay the Sub-Adviser the difference between $350,000 and the amount the Adviser has paid the Sub-Adviser under this Agreement for that year. The Sub-Adviser will pay its expenses incurred in performing its duties under this Agreement. Neither the Trust nor the Fund shall be liable to the Sub-Adviser for the compensation of the Sub-Adviser.

6. Limitation of Liability of the Sub-Adviser. The Sub-Adviser shall not be liable for any error of judgment or mistake of law or for any loss arising out of any investment or for any act or omission in the execution and management of the Fund, except for willful misfeasance, bad faith or gross negligence in the performance of its duties and obligations hereunder. The Trust, on behalf of the Fund, may enforce any obligations of the Sub-Adviser under this Agreement and may recover directly from the Sub-Adviser for any liability it may have to the Fund.

7. Covenants of the Sub-Adviser. The Sub-Adviser agrees that it (a) will not deal with itself, "affiliated persons" of the Sub-Adviser, the Trustees of the Trust or the Fund's distributor, as principals, agents, brokers or dealers in making purchases or sales of securities or other property for the account of the Fund, except as permitted by the 1940 Act and the rules, regulations and orders thereunder and subject to the prior written approval of the Adviser, and except in accordance with Rule 17e-1 procedures as approved by the Trustees from time to time and (b) will comply with all other provisions of the then-current Prospectus and Statement as provided by the Adviser to the Sub-Adviser relative to the Sub-Adviser and its trustees, officers, employees and affiliates.

8. Representations, Warranties and Additional Agreements of the Sub-Adviser. The Sub-Adviser represents, warrants and agrees that:

(a) It: (i) is registered as an investment adviser under the U.S. Investment Advisers Act of 1940, as amended (the "Advisers Act") and is registered under the laws of any jurisdiction in which the Sub-Adviser is required to be registered as an investment adviser in order to perform its obligations under this Agreement, and will continue to be so registered for so long as this Agreement remains in effect; (ii) is not prohibited by the 1940 Act or the Advisers Act from performing the services contemplated by this Agreement;

The Sub-Adviser agrees that such records are the property of the Trust, and will be surrendered to the Trust promptly upon request.

(c) The Sub-Adviser has adopted a written code of ethics complying with the requirements of Rule 17j-1 under the 1940 Act and, if it has not already done so, will provide the Adviser and the Trust with a copy of such code of ethics, and upon any amendment to such code of ethics, promptly provide such amendment.

The Adviser also understands the Sub-Adviser may give advice and take action with respect to any of its other clients for its own account which may differ from the timing or nature of action taken by the Sub-Adviser, with respect to the Fund.

EXECUTION COPY

DISTRIBUTION AGREEMENT
COLUMBIA FUNDS

THIS AGREEMENT is made as of August 22, 2005, by and between each Massachusetts business trust or Oregon corporation (each trust or corporation, 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 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 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 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

3

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, 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

4

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 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

5

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 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.

6

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.

6.2. This Agreement is terminable with respect to a Fund or any Series, if applicable, without penalty, on not less than sixty (60) days' written notice, by the Fund's Board of Trustees or Board of Directors, as applicable, by vote of a majority (as defined in the 1940 Act) of the outstanding voting securities of such Fund or any Series, if applicable, or by the Distributor. 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 and the provisions of Sections 2, 3, 5, 6.2, 7, 8 and 9.

7. LIMITED RECOURSE

A reference to each Fund and the Trustees or Directors, as applicable, of each Fund refer respectively to the Fund created by the Declaration of Trust and the Trustees or Directors as Trustees or Directors but not individually or personally. A copy of the document establishing each Fund is filed with the Secretary of the Commonwealth of Massachusetts. All parties hereto acknowledge and agree that any and all liabilities of the Fund arising, directly or indirectly, under this Agreement will be satisfied solely out of the assets of the Fund and that no Trustee, officer, director or shareholder shall be personally liable for any such liabilities. All persons dealing with any Fund or any Series, if applicable, must look solely to the property

7

belonging to such Fund or any Series, if applicable, for the enforcement of any claims against the Fund.

8. MISCELLANEOUS.

8.1. No provision of this Agreement may be changed, waived, discharged or terminated orally, but only by an instrument in writing signed by the party against which an enforcement of the change, waiver, discharge or termination is sought.

8.2. This Agreement shall be governed by the laws of the Commonwealth of Massachusetts as in effect as of the date hereof and the applicable provisions of the 1940 Act. To the extent that the applicable law of the Commonwealth of Massachusetts, or any of the provisions herein, conflict with the applicable provisions of the 1940 Act, the latter shall control.

9. NOTICES.

Any notices under this Agreement shall be in writing, addressed and delivered or mailed postage paid to such address as may be designated for the receipt of such notice. Until further notice, it is agreed that the address of the Fund shall be One Financial Center, Boston, MA 02110, telefacsimile (617) 345-0919 Attention: Secretary, and that of the Distributor shall be c/o Columbia Management Services, Inc., Attn: Dealer File Department, 245 Summer St., Fl 3, Boston, MA 02110, telefacsimile (617) 742-2989.

10. COUNTERPARTS.

This Agreement may be executed in counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same agreement.


IN WITNESS WHEREOF, the parties hereto have caused this instrument to be executed by their officers designated below as of the day and year first above written.

Columbia Funds Trust IX

Boston, MA 02111

Re: Columbia Funds Trust IX (the "Trust") - Post-Effective Amendment No. 40 to the Registration Statement of the Trust on Form N-1A (File Nos. 2-99356; 811-43671)

Ladies and Gentlemen:

You have informed us that you propose to register under the Securities Act of 1933, as amended (the "Act"), and offer and sell from time to time shares of beneficial interest ("Shares") of the funds listed on Schedule A hereto (each a "Fund" and collectively, the "Funds"), each a series of the Trust.

We act as counsel for the Trust and are familiar with the actions taken by its Board of Trustees to authorize the issuance of the Shares. We have examined the Trust's Amended and Restated Agreement and Declaration of Trust and amendments thereto on file at the office of the Secretary of The Commonwealth of Massachusetts (collectively, the "Agreement and Declaration of Trust") and the Trust's Amended and Restated By-Laws. We have also examined and relied upon the original or copies of minutes of the meetings or written consents of the Board of Trustees of the Trust and such other documents, including certificates of officers of the Trust, as we have deemed necessary for purposes of rendering our opinions below. We have assumed the genuineness of the signatures on all documents examined by us, the authenticity of all documents submitted to us as originals and the conformity to the corresponding originals of all documents submitted to us as copies.

We assume that appropriate action has been taken to register or qualify the sale of the Shares under any applicable state and federal laws regulating offerings and sales of securities.

We express no opinion as to the laws of any jurisdiction other than The Commonwealth of Massachusetts and the United States of America. Further, we express no opinion as to the state securities or "Blue Sky" laws of any jurisdiction, including The Commonwealth of Massachusetts.

Insofar as this opinion relates to factual matters, we have made inquiries to officers of the Trust to the extent we believe reasonable with respect to such matters and have relied upon


ROPES & GRAY

Columbia Funds Trust IX 2- September 16, 2005

representations made by the Trust in the Agreement and Declaration of Trust and representations made to us by one or more officers of the Trust. Although we have not independently verified the accuracy of such representations, we do not know of the existence or absence of any fact contradicting such representations. Any reference herein to "our knowledge," "known to us" or any variation thereof shall mean the actual knowledge of lawyers in this firm who generally represent the Trust.

Based on the foregoing, we are of the opinion that the issue and sale by the Trust of an unlimited number of Shares of each Fund has been duly authorized under Massachusetts law. Upon the original issue and sale of any such authorized but unissued Shares and upon receipt by the Trust of the authorized consideration therefor in an amount not less than the applicable net asset value, the Shares so issued will be validly issued, fully paid and nonassessable by the Trust.

The Trust is an entity of the type commonly known as a "Massachusetts business trust." Under Massachusetts law, shareholders could, under certain circumstances, be held personally liable for the obligations of the Trust. However, the Agreement and Declaration of Trust disclaims shareholder liability for acts or obligations of the Trust and requires that a notice of such disclaimer be given in each note, bond, contract, instrument, certificate or undertaking entered into or executed by the Trust or its Trustees. The Agreement and Declaration of Trust provides that in case any shareholder or former shareholder shall be held to be personally liable solely by reason of his or her being or having been a shareholder and not because of his or her acts or omissions or for some other reason, the shareholder or former shareholder (or his or her heirs, executors, administrators or other legal representatives or, in the case of a corporation or other entity, its corporate or other general successor) shall be entitled to be held harmless from and indemnified against all loss and expense arising from such liability. Thus, the risk of a shareholder's incurring financial loss on account of shareholder liability is limited to circumstances in which the Trust would be unable to meet its obligations.

We understand that this opinion is to be used in connection with the registration of an indefinite number of Shares for offering and sale pursuant to the Act. We consent to the filing of this opinion with and as part of your Registration Statement on Form N-1A relating to such offering and sale.

Very truly yours,

/s/ Ropes & Gray LLP
