Permissible Investments and Related Risks

The Fund’s prospectus identifies and summarizes the individual types of securities in which the Fund invests as part of its principal investment strategies and the principal risks associated with such investments.

The table below identifies for the Fund certain types of securities in which it is permitted to invest, including certain types of securities that are described in the Fund’s prospectus. The Fund generally has the ability to invest 10% or more of its total assets in each type of security described in its prospectus (and in each sub-category of such security type described in this SAI). To the extent that a type of security identified below is not described in the Fund’s prospectus (or as a sub-category of such security type in this SAI), the Fund generally invests less than 10% of the Fund’s total assets in such security type.

Information about individual types of securities (including certain of their associated risks) in which the Fund may invest is set forth below. The Fund’s investment in these types of securities is subject to its investment objective and fundamental and non-fundamental investment policies.

Temporary Defensive Positions. The Fund may temporarily invest in money market instruments or hold cash. It may do so without limit, when the Advisor or the Fund’s sub-advisor, if applicable: (i) believes that the market conditions are not favorable for profitable investing; (ii) is unable to locate favorable investment opportunities or (iii) determines that a temporary defensive position is advisable or necessary in order to meet anticipated redemption requests, or for other reasons. While the Fund engages in such strategies, it may not achieve its investment objective.

Asset-Backed Securities

Asset-backed securities represent interests in, or debt instruments that are backed by, pools of various types of assets that generate cash payments generally over fixed periods of time. Such securities entitle the security holders to receive distributions that are tied to the payments made on the underlying assets (less fees paid to the originator, servicer, or other parties, and fees paid for credit enhancement), so that the payments made on the underlying assets effectively pass through to such security holders. Asset-backed securities typically are created by an originator of loans or owner of accounts receivable that sells such underlying assets to a special purpose entity in a process called a securitization. The special purpose entity issues securities that are backed by the payments on the underlying assets, and have a minimum denomination and specific term. Asset-backed securities may be structured as fixed-, variable- or floating-rate obligations or as zero-coupon, pay-in-kind and step-coupon securities and may be privately placed or publicly offered. See Permissible Fund Investments — Variable- and Floating-Rate Obligations , Permissible Fund Investments — Zero-Coupon, Pay-in-Kind and Step-Coupon Securities and Permissible Fund Investments — Private Placement and Other Restricted Securities for more information.

Investing in asset-backed securities is subject to certain risks. For example, the value of asset-backed securities may be affected by, among other factors, changes in: interest rates, the market’s assessment of the quality of underlying assets, the creditworthiness of the servicer for the underlying assets, information concerning the originator of the underlying assets, or the creditworthiness or rating of the entities that provide any supporting letters of credit, surety bonds, derivative instruments, or other credit enhancement. The value of asset-backed securities also will be affected by the exhaustion, termination or expiration of any credit enhancement.

Declining or low interest rates may lead to a more rapid rate of repayment on the underlying assets, resulting in accelerated payments on asset-backed securities that then would be reinvested at a lesser rate of interest. Rising or high interest rates tend to lead to a slower rate of repayment on the underlying assets, resulting in slower than expected payments on asset-backed securities that can, in turn, lead to a decline in value. The impact of changing interest rates on the value of asset-backed securities may be difficult to predict and result in greater volatility. Holders of asset-backed securities generally have no recourse against the originator of the underlying assets in the

event of a default on the underlying assets. Credit risk reflects the risk that a holder of asset-backed securities, backed by pools of receivables such as mortgage loans, may not receive all or part of its principal because the issuer, any credit enhancer and/or an underlying obligor has defaulted on its obligations. Credit risk is increased for asset-backed securities that are subordinated to another security (i.e., if the holder of an asset-backed security is entitled to receive payments only after payment obligations to holders of the other security are satisfied). The more deeply subordinated the security, the greater the credit risk associated with the security will be.

Bank Obligations (Domestic and Foreign)

Bank obligations include certificates of deposit, bankers’ acceptances, time deposits and promissory notes that earn a specified rate of return and may be issued by (i) a domestic branch of a domestic bank, (ii) a foreign branch of a domestic bank, (iii) a domestic branch of a foreign bank or (iv) a foreign branch of a foreign bank. Bank obligations may be structured as fixed-, variable- or floating-rate obligations. See Permissible Fund Investments — Variable- and Floating-Rate Obligations for more information.

Certificates of deposit, or so-called CDs, typically are interest-bearing debt instruments issued by banks and have maturities ranging from a few weeks to several years. Bankers’ acceptances are time drafts drawn on and accepted by banks, are a customary means of effecting payment for merchandise sold in import-export transactions and are a general source of financing. Yankee dollar certificates of deposit are negotiable CDs issued in the United States by branches and agencies of foreign banks. Eurodollar certificates of deposit are CDs issued by foreign (mainly European) banks with interest and principal paid in U.S. dollars. Such CDs typically have maturities of less than two years and have interest rates that typically are pegged to the London Interbank Offered Rate or LIBOR. A time deposit can be either a savings account or CD that is an obligation of a financial institution for a fixed term. Typically, there are penalties for early withdrawals of time deposits. Promissory notes are written commitments of the maker to pay the payee a specified sum of money either on demand or at a fixed or determinable future date, with or without interest.

Bank investment contracts are issued by banks. Pursuant to such contracts, the Fund may make cash contributions to a deposit fund of a bank. The bank then credits to the Fund payments at floating or fixed interest rates. The Fund also may hold funds on deposit with its custodian for temporary purposes.

Investing in bank obligations is subject to certain risks. Certain bank obligations, such as some CDs, are insured by the FDIC up to certain specified limits. Many other bank obligations, however, are neither guaranteed nor insured by the FDIC or the U.S. Government. These bank obligations are “backed” only by the creditworthiness of the issuing bank or parent financial institution. Domestic and foreign banks are subject to different governmental regulation. Accordingly, certain obligations of foreign banks, including Eurodollar and Yankee dollar obligations, involve different investment risks than those affecting obligations of domestic banks, including, among others, the possibilities that: (i) their liquidity could be impaired because of political or economic developments; (ii) the obligations may be less marketable than comparable obligations of domestic banks; (iii) a foreign jurisdiction might impose withholding and other taxes at high levels on interest income; (iv) foreign deposits may be seized or nationalized; (v) foreign governmental restrictions such as exchange controls may be imposed, which could adversely affect the payment of principal or interest on those obligations; (vi) there may be less publicly available information concerning foreign banks issuing the obligations; and (vii) the reserve requirements and accounting, auditing and financial reporting standards, practices and requirements applicable to foreign banks may differ from those applicable to domestic banks. Foreign banks generally are not subject to examination by any U.S. Government agency or instrumentality.

Convertible Securities

Convertible securities include 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). As such, convertible securities combine the investment characteristics of debt securities and equity securities. A holder of convertible securities is entitled to receive the income of a bond, debenture or note or the dividend of a preferred stock until the conversion privilege is exercised. The market value of convertible securities generally is a function of, among other factors, interest rates, the rates of return of similar nonconvertible securities and the financial strength of the issuer. The market value of convertible securities tends to decline as interest rates rise and, conversely, to rise 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

10

Table of Contents

the underlying common stock declines, the price of the convertible security tends to be influenced more by the rate of return of the convertible security. Because both interest rate and market movements can influence their value, convertible securities generally are not as sensitive to changes in interest rates as similar debt securities nor generally are they as sensitive to changes in share price as their underlying common stock. Convertible securities may be structured as fixed-, variable- or floating-rate obligations or as zero-coupon, pay-in-kind and step-coupon securities and may be privately placed or publicly offered. See Permissible Fund Investments — Variable- and Floating-Rate Obligations , Permissible Fund Investments — Zero-Coupon, Pay-in-Kind and Step-Coupon Securities and Permissible Fund Investments — Private Placement and Other Restricted Securities for more information.

Investing in convertible securities is subject to certain risks. Certain convertible securities, particularly securities that are convertible into securities of an issuer other than the issuer of the convertible security, may be illiquid and, therefore, may be more difficult to resell in a timely fashion or for a fair price, which could result in investment losses. Certain convertible securities may have a mandatory conversion feature, pursuant to which the securities convert automatically into common stock or other equity securities (of the same or a different issuer) at a specified date and a specified exchange ratio. Certain convertible securities may be convertible at the option of the issuer, which may require a holder to convert the security into the underlying common stock, even at times when the value of the underlying common stock or other equity security has declined substantially.

In addition, some convertible securities may be rated below investment grade or may not be rated and, therefore, may be considered speculative investments. Companies that issue convertible securities frequently are small- and mid-capitalization companies and, accordingly, carry the risks associated with such companies. In addition, the credit rating of a company’s convertible securities generally is lower than that of its conventional debt securities. Convertible securities are senior to equity securities and have a claim to the assets of an issuer prior to the holders of the issuer’s common stock in the event of liquidation but generally are subordinate to similar non-convertible debt securities of the same issuer. Some convertible securities are particularly sensitive to changes in interest rates when their predetermined conversion price is much higher than the price for the issuing company’s common stock.

Corporate Debt Securities

Corporate debt securities are fixed income securities typically issued by businesses to finance their operations. Notes, bonds, debentures and commercial paper are the most common types of corporate debt securities, with the primary difference being their interest rates, maturity dates and secured or unsecured status. Commercial paper has the shortest term and usually is unsecured. The broad category of corporate debt securities includes debt issued by domestic or foreign companies of all kinds, including those with small-, mid- and large-capitalizations. Corporate debt securities may be rated investment grade or below investment grade and may be structured as fixed-, variable- or floating-rate obligations or as zero-coupon, pay-in-kind and step-coupon securities and may be privately placed or publicly offered. See Permissible Fund Investments — Variable- and Floating-Rate Obligations , Permissible Fund Investments — Zero-Coupon, Pay-in-Kind and Step-Coupon Securities and Permissible Fund Investments — Private Placement and Other Restricted Securities for more information.

Extendible commercial notes (ECNs) are very similar to commercial paper except that with ECNs, the issuer has the option to extend the notes’ maturity. ECNs are issued at a discount rate, with an initial redemption of not more than 90 days from the date of issue. If ECNs are not redeemed by the issuer on the initial redemption date, the issuer will pay a premium (step-up) rate based on the ECN’s credit rating at the time.

Because of the wide range of types and maturities of corporate debt securities, as well as the range of creditworthiness of issuers, corporate debt securities can have widely varying risk/return profiles. For example, commercial paper issued by a large established domestic corporation that is rated by an NRSRO as investment grade may have a relatively modest return on principal but present relatively limited risk. On the other hand, a long-term corporate note issued, for example, by a small foreign corporation from an emerging market country that has not been rated by an NRSRO may have the potential for relatively large returns on principal but carries a relatively high degree of risk.

Investing in corporate debt securities is subject to certain risks including, among others, credit and interest rate risk. Credit risk is the risk that the Fund could lose money if the issuer of a corporate debt security is unable to pay interest or repay principal when it becomes due. Some corporate debt securities that are rated below investment grade by an NRSRO generally are considered speculative because they present a greater risk of loss, including default, than higher quality debt securities. The credit risk of a particular issuer’s debt security may vary based on its priority for repayment. For example, higher ranking (senior) debt securities have a higher priority than and, therefore, may be

11

Table of Contents

paid in full before, lower ranking (subordinated) securities. In addition, in the event of bankruptcy, holders of higher-ranking senior securities may receive amounts otherwise payable to the holders of more junior securities. Interest rate risk is the risk that the value of certain corporate debt securities will tend to fall when interest rates rise. In general, corporate debt securities with longer terms tend to fall more in value when interest rates rise than do corporate debt securities with shorter terms.

Derivatives

General

Derivatives are financial instruments whose values are based on (or “derived” from) traditional securities (such as a stock or a bond), assets (such as a commodity, like gold), reference rates (such as LIBOR) or market indices (such as the S&P 500 ^® Index). Some forms of derivatives, such as exchange-traded futures and options on securities, commodities, or indices, are traded on regulated exchanges. These types of derivatives are standardized contracts that 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. Derivatives afford leverage and, when used properly, can enhance returns and be useful in hedging portfolios. Some common types of derivatives include futures; options; options on futures; forward foreign currency exchange contracts; forward contracts on securities and securities indices; linked securities and structured products; CMOs; stripped securities; warrants; swap agreements and swaptions.

The Fund may use derivatives for a variety of reasons, including, for example: (i) to enhance its return; (ii) to attempt to protect against possible changes in the market value of securities held in or to be purchased for its portfolio resulting from securities markets or currency exchange rate fluctuations (i.e., to hedge); (iii) to protect its unrealized gains reflected in the value of its portfolio securities; (iv) to facilitate the sale of such securities for investment purposes; (v) to reduce transaction costs; and/or (vi) to manage the effective maturity or duration of its portfolio.

The Fund’s use of derivatives presents risks different from, and possibly greater than, the risks associated with investing directly in traditional securities. The use of derivatives can lead to losses because of adverse movements in the price or value of the underlying security, asset, index or reference rate, which may be magnified by certain features of the derivatives. These risks are heightened when the Fund uses derivatives to enhance its return or as a substitute for a position or security, rather than solely to hedge or offset the risk of a position or security held by the Fund. There is also a risk that the derivative will not correlate well with the security for which it is substituting. The Fund’s use of derivatives to leverage risk also may exaggerate a loss, potentially causing the Fund to lose more money than if it had invested in the underlying security, or limit a potential gain. The success of management’s derivative strategies will depend on its ability to assess and predict the impact of market or economic developments on the underlying security, asset, index or reference rate and the derivative itself, without necessarily the benefit of observing the performance of the derivative under all possible market conditions. Other risks arise from the Fund’s potential inability to terminate or sell its derivative positions as a liquid secondary market for such positions may not exist at times when the Fund may wish to terminate or sell them. Over-the-counter instruments (investments not traded on an exchange) may be illiquid. Derivatives traded in the over-the-counter market are subject to the risk that the other party will not meet its obligations. Also, with some derivative strategies there is the risk that the Fund may not be able to find a suitable derivative transaction counterparty, and thus may be unable to invest in derivatives altogether. The use of derivatives may also increase the amount and accelerate the timing of taxes payable by shareholders.

The Fund may use any or all of the above investment techniques and may purchase different types of derivative instruments at any time and in any combination. There is no particular strategy that dictates the use of one technique over another, as the use of derivatives is a function of numerous variables, including market conditions.

Futures Contracts and Options on Futures Contracts

Futures Contracts. A futures contract sale creates an obligation by the seller to deliver the type of security or other asset called for in the contract at a specified delivery time for a stated price. A futures contract purchase creates an obligation by the purchaser to take delivery of the type of security or other asset called for in the contract at a specified delivery time for a stated price. The specific security or other asset delivered or taken at the settlement date is not determined until on or near that date. The determination is made in accordance with the rules of the exchange 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 security or other asset. Futures exchanges and trading in the United States are regulated under the Commodity Exchange Act (CEA) by the Commodity Futures Trading Commission (CFTC), a U.S. Government agency.

12

Table of Contents

Traders in futures contracts may be broadly classified as either “hedgers” or “speculators.” Hedgers use the futures markets primarily to offset unfavorable changes (anticipated or potential) in the value of securities or other assets currently owned or expected to be acquired by them. Speculators less often own the securities or other assets underlying the futures contracts which they trade, and generally use futures contracts with the expectation of realizing profits from fluctuations in the value of the underlying securities or other assets. Pursuant to a notice of eligibility claiming exclusion from the definition of commodity pool operator filed with the CFTC and the National Futures Association on behalf of the Fund, neither the Trust nor the individual Fund is deemed to be a “commodity pool operator” under the CEA, and, accordingly, they are not subject to registration or regulation as such under the CEA.

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.

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 in order to initiate and maintain open positions in futures contracts. 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 intended to assure completion of the contract (delivery or acceptance of the underlying security or other asset) that is returned to the Fund upon termination of the futures contract, assuming all contractual obligations have been satisfied. Minimum initial margin requirements are established by the relevant futures exchange and may be changed. Brokers may establish deposit requirements which are higher than the exchange minimums. Futures contracts are customarily purchased and sold on margin which may range upward from less than 5% of the value of the contract being traded. 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 other asset fluctuates, a process known as “marking to market.” If the futures contract price changes to the extent that the margin on deposit does not satisfy margin requirements, payment of additional variation margin will be required. Conversely, a change in the contract value may reduce the required margin, resulting in a repayment of excess margin to the contract holder. Variation margin payments are made for as long as the contract remains open. The Fund expects to earn interest income on its margin deposits.

Although futures contracts by their terms call for actual delivery or acceptance of securities or other assets (stock index futures contracts or futures contracts that reference other intangible assets do not permit delivery of the referenced assets), the contracts usually are closed out before the settlement date without the making or taking of delivery. The Fund may elect to close some or all of its futures positions at any time prior to their expiration. The purpose of taking such action would be to reduce or eliminate the position then currently held by the Fund. Closing out an open futures position is done by taking an opposite position (“buying” a contract which has previously been “sold,” “selling” a contract previously “purchased”) in an identical contract (i.e., the same aggregate amount of the specific type of security or other asset with the same delivery date) to terminate the position. Final determinations are made as to whether the price of the initial sale of the futures contract exceeds or is below the price of the offsetting purchase, or whether the purchase price exceeds or is below the offsetting sale price. 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. Brokerage commissions are incurred when a futures contract is bought or sold.

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 and commodities markets. This requires different skills and techniques than those required to predict changes in the prices of individual securities. The Fund, therefore, bears the risk that future market trends will be incorrectly predicted.

The risk of loss in trading futures contracts in some strategies can be substantial, due both to the relatively low margin deposits required and the potential for an extremely high degree of leverage involved in futures contracts. As a result, a relatively small price movement in a futures contract may result in an immediate and substantial loss to the investor. For example, if at the time of purchase, 10% of the value of the futures contract is deposited as margin, a subsequent 10% decrease in the value of the futures contract would result in a total loss of the margin deposit, before any deduction for the transaction costs, if the account were then closed out. A 15% decrease would result in a loss equal to 150% of the original margin deposit if the contract were closed out. Thus, a purchase or sale of a futures contract may result in losses in excess of the amount posted as initial margin for the contract.

13

Table of Contents

In the event of adverse price movements, the Fund would continue to be required to make daily cash payments in order to maintain its required margin. In such a situation, if the Fund has insufficient cash, it may have to sell portfolio securities in order to meet daily margin requirements at a time when it may be disadvantageous to do so. The inability to close the futures position also could have an adverse impact on the ability to hedge effectively.

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, which may limit the Fund’s ability to realize its profits or limit its losses. 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; (ii) restrictions may be imposed by an exchange on opening transactions, closing transactions or both; (iii) trading halts, suspensions or other restrictions may be imposed with respect to particular classes or series of contracts, or underlying securities; (iv) unusual or unforeseen circumstances, such as volume in excess of trading or clearing capability, may interrupt normal operations on an exchange; (v) the facilities of an exchange or a clearing corporation may not at all times be adequate to handle current trading volume; or (vi) one or more exchanges could, for economic or other reasons, decide or be compelled at some future date to discontinue the trading of contracts (or a particular class or series of contracts), in which event the secondary market on that exchange (or in the class or series of contracts) would cease to exist, although outstanding contracts 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.

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, 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 Fund may use interest rate futures contracts as a defense, or hedge, against anticipated interest rate changes. The Fund presently could accomplish a similar result to that which it hopes to achieve through the use of interest rate 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 bonds with short maturities and investing in bonds with long maturities 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 Fund, 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. Each exchange guarantees performance under contract provisions through a clearing corporation, a nonprofit organization managed by the exchange membership. A public market exists in futures contracts covering various financial instruments including long-term U.S. Treasury Bonds and Notes; GNMA modified pass-through mortgage backed securities; three-month U.S. Treasury Bills; and ninety-day commercial paper. The Fund may also invest in exchange-traded Eurodollar contracts, which are interest rate futures on the forward level of LIBOR. These contracts are generally considered liquid securities and trade on the Chicago Mercantile Exchange. Such Eurodollar contracts are generally used to “lock-in” or hedge the future level of short-term rates. The Fund may trade in any interest rate futures contracts for which there exists a public market, including, without limitation, the foregoing instruments.

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 in the index. 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).

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 hedges. 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.

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.

Options on Futures Contracts. The Fund may purchase and write call and put options on those futures contracts that it is permitted to buy or sell. The Fund may use such options on futures contracts in lieu of writing options directly on the underlying securities or other assets 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. A futures option gives the holder, in return for the premium paid, the right to buy from (call) or sell to (put) the writer of the option a futures contract at a specified price at any time during the period of the option. Upon exercise, the writer of the option is obligated to pay the difference between the cash value of the futures contract and the exercise price. Like the buyer or seller of a futures contract, the holder or writer of an option has the right to terminate its position prior to the scheduled expiration of the option by selling or purchasing an option of the same series, at which time the person entering into the closing purchase transaction will realize a gain or loss. There is no guarantee that such closing purchase transactions can be effected.

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 underlying security’s or other asset’s value (less any applicable margin deposits) have been deposited in a segregated account. 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.

Investments in futures options involve some of the same risks that are involved in connection with investments in futures contracts (for example, the existence of a liquid secondary market). In addition, the purchase of an option also entails the risk that changes in the value of the underlying futures contract will not be fully reflected in the value of the option purchased. 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. In general, the market prices of options can be expected to be more volatile than the market prices on the underlying futures contracts. Compared to the purchase or sale of futures contracts, however, the purchase of call or put options on futures contracts may frequently involve less potential risk to the Fund because the maximum amount at risk is the premium paid for the options (plus transaction costs).

Successful use of index futures by the Fund is also subject to the Advisor’s ability to predict correctly movements in the direction of the market. It is possible that, for example, 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 occurred, the Fund would lose money on the futures and also experience a decline in the value of its portfolio securities, as the Fund’s ability to effectively hedge all or a portion of the securities in its portfolio, in anticipation of or during a market decline, through transactions in futures or put options on stock indices, depends on the degree to which price movements in the underlying index correlate with the price movements of the securities held by the Fund. Inasmuch as the Fund’s securities will not duplicate the components of an index, the correlation will not be perfect. Consequently, the Fund bears the risk that the prices of its securities being hedged will not move to the same extent as do the prices of its put options on the stock indices. 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

15

Table of Contents

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 an 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.

There is also the risk of loss by the Fund of margin deposits in the event of bankruptcy of a broker with whom the Fund has an open position in a futures contract or related option. Most futures exchanges limit the amount of fluctuation permitted in some contract prices during a single trading day. The daily limit establishes the maximum amount that the price of a futures contract may vary either up or down from the previous day’s settlement price at the end of a trading session. Once the daily limit has been reached in a particular type of contract, no trades may be made on that day at a price beyond that limit. The daily limit governs only price movement during a particular trading day and, therefore, does not limit potential losses, because the limit may prevent the liquidation of unfavorable positions. Futures contract prices have occasionally moved to the daily limit for several consecutive trading days with little or no trading, thereby preventing prompt liquidation of futures positions and subjecting some futures traders to substantial losses.

Options on Index Futures Contracts. The Fund may also purchase and sell options on index futures contracts. Options on index futures give the purchaser the right, in return for the premium paid, to assume a position in an index futures contract (a long position if the option is a call and a short position if the option is a put), at a specified exercise price at any time during the period of the option. Upon exercise of the option, the delivery of the futures position by the writer of the option to the holder of the option will be accompanied by delivery of the accumulated balance in the writer’s futures margin account, which represents the amount by which the market price of the index futures contract, at exercise, exceeds (in the case of a call) or is less than (in the case of a put) the exercise price of the option on the index future. If an option is exercised on the last trading day prior to the expiration date of the option, the settlement will be made entirely in cash equal to the difference between the exercise price of the option and the closing level of the index on which the future is based on the expiration date. Purchasers of options who fail to exercise their options prior to the exercise date suffer a loss of the premium paid.

There are various risks in connection with the use by the Fund of index futures as a hedging device. For example, a 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 hedges. 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; there can be no assurance that the Advisor will be successful in doing so.

Stock Options and Stock Index Options

The Fund may purchase and write (i.e., sell) put and call options. Such options may relate to particular stocks or stock indices, and may or may not be listed on a domestic or foreign securities exchange and may or may not be issued by the Options Clearing Corporation (OCC). Stock index options are put options and call options on various stock indices. In most respects, they are identical to listed options on common stocks.

There is a key difference between stock options and stock index options in connection with their exercise. In the case of stock options, the underlying security, common stock, is delivered. However, upon the exercise of an index option, settlement does not occur by delivery of the securities comprising the index. The option holder who exercises the index option receives an amount of cash if the closing level of the stock index upon which the option is based is greater than (in the case of a call) or less than (in the case of a put) the exercise price of the option. This amount of cash is equal to the difference between the closing price of the stock index and the exercise price of the option expressed in dollars times a specified multiple. A stock index fluctuates with changes in the market value of the securities included in the index. For example, some stock index options are based on a broad market index, such as the S&P 500 ^® Index or a narrower market index, such as the S&P 100 Index. Indices may also be based on an industry or market segment.

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 for such 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. The writer in such circumstances would be subject to the risk of market decline or appreciation in the instrument during such period. If an option purchased by the Fund expires unexercised, the Fund will realize a loss equal to the premium paid. Reasons for the absence of a liquid secondary market on an exchange include the following: (i) there may be insufficient trading interest in certain 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 options, or underlying securities; (iv) unusual or unforeseen circumstances, such as volume in excess of trading or clearing capability, may interrupt normal operations on an exchange; (v) the facilities of an exchange or a clearing corporation may not at all times be adequate to handle current trading volume; or (vi) one or more exchanges could, for economic or other reasons, decide or be compelled at some future date to discontinue the trading of options (or a particular class or series of options), in which event the secondary market on that exchange (or in the class or series of options) would cease to exist, although outstanding 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.

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 OCC or other options markets may impose exercise restrictions. If a prohibition on exercise is imposed at a 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.

Dealer (Over-the-Counter) Options. Dealer options are options negotiated individually through dealers rather than traded on an exchange. Certain risks are specific to dealer options. While the Fund might look to a clearing corporation to exercise exchange-traded options, if the Fund purchases a dealer option it must rely on the selling dealer to perform if the Fund exercises the option. Failure by the dealer to do so would result in the loss of the premium paid by the Fund as well as loss of the expected benefit of the transaction. Exchange-traded options generally have a continuous liquid market while dealer options more often may not. Consequently, the Fund can realize the value of a dealer option it has purchased only by exercising or reselling the option to the issuing dealer. Similarly, when the Fund writes a dealer option, the Fund can close out the option prior to its expiration only by entering into a closing purchase transaction with the dealer. While each Fund seeks to enter into dealer options only with dealers who will agree to and can enter into closing transactions with the Fund, no assurance exists that the Fund will at any time be able to liquidate a dealer option at a favorable price at any time prior to expiration. Unless the Fund, as a covered dealer call option writer, can effect a closing purchase transaction, it will not be able to liquidate securities (or other assets) used as cover until the option expires or is exercised. In the event of insolvency of the other party, the Fund may be unable to liquidate a dealer option. With respect to options written by the Fund, the inability to enter into a closing transaction may result in material losses to the Fund. For example, because the Fund must maintain a secured position with respect to any call option on a security it writes, the Fund may not sell the assets that it has segregated to secure the position while it is obligated under the option. This requirement may impair the Fund’s ability to sell portfolio securities at a time when such sale might be advantageous.

The Fund generally will treat purchased dealer options as illiquid securities. The Fund may treat the cover used for written dealer options as liquid if the dealer agrees that the Fund may repurchase the dealer option it has written for a maximum price to be calculated by a predetermined formula. In such cases, the dealer option would be considered illiquid only to the extent the maximum purchase price under the formula exceeds the intrinsic value of the option.

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 the stated exercise price at any time prior to the expiration date of the option, regardless of the security’s market price; put options give the purchaser the right to sell the underlying securities to the Fund at the stated exercise price at any time prior to the expiration date of the option, regardless of the security’s market 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 (straddles) 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 the security’s then-current market value, resulting in a potential capital loss unless the security subsequently appreciates in value.

The Fund’s obligation to sell an instrument subject to a call option written by it, or to purchase an instrument subject to a put option written by it, may be terminated prior to the expiration date of the option by the Fund’s execution of a closing purchase transaction, which is effected by purchasing on an exchange an offsetting option of the same series (i.e., same underlying instrument, exercise price and expiration date) as the option previously written. A closing purchase transaction will ordinarily be effected in order to realize a profit on an outstanding option, to prevent an underlying instrument from being called, to permit the sale of the underlying instrument or to permit the writing of a new option containing different terms on such underlying instrument. The Fund realizes a profit or loss from a closing purchase 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 also 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.

Swap Agreements

Swap agreements are derivative instruments that can be individually negotiated and structured to include exposure to a variety of different types of investments or market factors. Depending on their structure, swap agreements may increase or decrease the Fund’s exposure to long- or short-term interest rates, foreign currency values, mortgage securities, corporate borrowing rates, or other factors such as security prices or inflation rates. The Fund may enter into a variety of swap agreements, including interest rate, index, commodity, equity, credit default and currency exchange rate swap agreements, and other types of swap agreements such as caps, collars and floors. The Fund also may enter into swaptions, which are options to enter into a swap agreement.

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. In a total return swap agreement, the non-floating rate side of the swap is based on the total return of an individual security, a basket of securities, an index or another reference asset. 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. Caps and floors have an effect similar to buying or writing options. A collar combines elements of buying a cap and selling a floor.

Swap agreements will tend to shift the Fund’s investment exposure from one type of investment to another. For example, if the Fund agreed to pay fixed rates in exchange for floating rates while holding fixed-rate bonds, the swap would tend to decrease the Fund’s exposure to long-term interest rates. Another example is if the Fund agreed to exchange payments in dollars for payments in foreign currency, the swap agreement would tend to decrease the Fund’s exposure to U.S. interest rates and increase its exposure to foreign currency and interest rates.

Swap agreements are sophisticated hedging instruments that typically involve a small investment of cash relative to the magnitude of risks assumed. As a result, swaps can be highly volatile and may have a considerable impact on the Fund’s performance. Depending on how they are used, swap agreements may increase or decrease the overall volatility of the Fund’s investments and its share price and yield. Additionally, whether the Fund’s use of swap agreements will be successful in furthering its investment objective will depend on the Advisor’s ability correctly to predict whether certain types of investments likely are to produce greater returns than other investments. Because they are two party contracts and because they may have terms of greater than seven days, swap agreements may be considered to be illiquid. Moreover, the Fund bears the risk of loss of the amount expected to be received under a swap agreement in the event of the default or bankruptcy of a swap agreement counterparty. The most significant factor in the performance of swap agreements is the change in the specific interest rate, currency, or other factor that determines the amounts of payments due to and from the Fund. If a swap agreement calls for payments by the Fund, the Fund must be prepared to make such payments when due. In addition, if the counterparty’s creditworthiness declines, the value of a swap agreement likely would decline, potentially resulting in losses for the Fund. The Fund will closely monitor the credit of a swap agreement counterparty in order to attempt to minimize this risk. The Fund may also suffer losses if it is unable to terminate outstanding swap agreements (either by assignment or other disposition) or reduce its exposure through offsetting transactions (i.e., by entering into an offsetting swap agreement with the same party or a similarly creditworthy party).

Credit Default Swap Agreements. The Fund may enter into credit default swap agreements, which may have as reference obligations one or more securities or a basket of securities that are or are not currently held by the Fund. The protection “buyer” in a credit default contract is generally obligated to pay the protection “seller” an upfront or a periodic stream of payments over the term of the contract provided that no credit event, such as a default, on a reference obligation has occurred. If a credit event occurs, the seller generally must pay the buyer the “par value” (full notional value) of the swap in exchange for an equal face amount of deliverable obligations of the reference entity described in the swap, or the seller may be required to deliver the related net cash amount, if the swap is cash settled. The Fund may be either the buyer or seller in the transaction. If the Fund is a buyer and no credit event occurs, the Fund may recover nothing if the swap is held through its termination date. However, if a credit event occurs, the buyer generally may elect to receive the full notional value of the swap in exchange for an equal face amount of deliverable obligations of the reference entity whose value may have significantly decreased. As a seller, the Fund generally receives an upfront payment or a fixed rate of income throughout the term of the swap provided that there is no credit event. As the seller, the Fund would effectively add leverage to its portfolio because, in addition to its total net assets, the Fund would be subject to investment exposure on the notional amount of the swap.

Credit default swap agreements may involve greater risks than if the Fund had invested in the reference obligation directly since, in addition to risks relating to the reference obligation, credit default swaps are subject to illiquidity risk, counterparty risk and credit risk. The Fund will enter into credit default swap agreements generally with counterparties that meet certain standards of creditworthiness. A buyer generally will lose its investment and recover nothing if no credit event occurs and the swap is held to its termination date. If a credit event were to occur, the value of any deliverable obligation received by the seller, coupled with the upfront or periodic payments previously received, may be less than the full notional value it pays to the buyer, resulting in a loss of value to the seller.

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.

The values of equity swaps can be very volatile. To the extent that the Advisor does not accurately analyze and predict the potential relative fluctuation on the components swapped with the other party, the Fund may suffer a loss. The value of some components of an equity swap (such as the dividend on a common stock) may also be sensitive to changes in interest rates. Furthermore, during the period a swap is outstanding, the Fund may suffer a loss if the counterparty defaults.

Total Return Swap Agreements. Total return swap agreements are contracts in which one party agrees to make periodic payments to another party based on the change in market value of the assets underlying the contract, which may include a specified security, basket of securities or securities indices during the specified period, in return for periodic payments based on a fixed or variable interest rate or the total return from other underlying assets. Total return swap agreements may be used to obtain exposure to a security or market without owning or taking physical custody of such security or investing directly in such market. Total return swap agreements may effectively add leverage to the Fund’s portfolio because, in addition to its total net assets, the Fund would be subject to investment exposure on the notional amount of the swap.

Total return swap agreements are subject to the risk that a counterparty will default on its payment obligations to the Fund thereunder, and conversely, that the Fund will not be able to meet its obligation to the counterparty. Generally, the Fund will enter into total return swaps on a net basis (i.e., the two payment streams are netted against one another with the Fund receiving or paying, as the case may be, only the net amount of the two payments). The net amount of the excess, if any, of the Fund’s obligations over its entitlements with respect to each total return swap will be accrued on a daily basis, and an amount of liquid assets having an aggregate net asset value at least equal to the accrued excess will be segregated by the Fund. If the total return swap transaction is entered into on other than a net basis, the full amount of the Fund’s obligations will be accrued on a daily basis, and the full amount of the Fund’s obligations will be segregated by the Fund in an amount equal to or greater than the market value of the liabilities under the total return swap agreement or the amount it would have cost the Fund initially to make an equivalent direct investment, plus or minus any amount the Fund is obligated to pay or is to receive under the total return swap agreement.

Variance, Volatility and Correlation Swap Agreements. Variance and volatility swaps are contracts that provide exposure to increases or decreases in the volatility of certain referenced assets. Correlation swaps are contracts that provide exposure to increases or decreases in the correlation between the prices of different assets or different market rates.

Dollar Rolls

Dollar rolls involve selling securities (e.g., mortgage-backed securities or U.S. Treasury securities) and simultaneously entering into a commitment to purchase those or similar (same collateral type, coupon and maturity) securities on a specified future date and price. Mortgage dollar rolls and U.S. Treasury rolls are types of dollar rolls. The Fund foregoes principal and interest paid on the securities during the “roll” period. The Fund is compensated by the difference between the current sales price and the lower forward price for the future purchase of the securities as well as the interest earned on the cash proceeds of the initial sale.

Dollar rolls involve the risk that the market value of the securities the Fund is obligated to repurchase may decline below the repurchase price or that the transaction costs may exceed the return earned by the Fund from the transaction. Dollar rolls also involve risk to the Fund if the other party should default on its obligation and the Fund is delayed or prevented from completing the transaction. In the event that the buyer of securities under a dollar roll files for bankruptcy or becomes insolvent, the Fund’s use of proceeds of the dollar roll may be restricted pending a determination by the other party, or its trustee or receiver, whether to enforce the Fund’s obligation to repurchase the securities. 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.

Foreign Securities

Foreign securities include debt, equity and derivative securities that the Advisor determines are “foreign” based on the consideration of an issuer’s domicile, its principal place of business, its primary stock exchange listing, the source of its revenue or other factors. Foreign securities may be structured as fixed-, variable- or floating-rate obligations or as zero-coupon, pay-in-kind and step-coupon securities and may be privately placed or publicly offered. See Permissible Fund Investments — Variable- and Floating-Rate Obligations , Permissible Fund Investments — Zero-Coupon, Pay-in-Kind and Step-Coupon Securities and Permissible Fund Investments — Private Placement and Other Restricted Securities for more information.

Foreign securities may include depositary receipts, such as American Depositary Receipts (ADRs), European Depositary Receipts (EDRs) and Global Depositary Receipts (GDRs). ADRs are U.S. dollar- denominated receipts issued in registered form by a domestic bank or trust company that evidence ownership of underlying securities issued by a foreign issuer. EDRs are foreign currency-denominated receipts issued in Europe, typically by foreign banks or trust companies and foreign branches of domestic banks, that evidence ownership of foreign or domestic securities. GDRs are receipts structured similarly to ADRs and EDRs and are marketed globally. Depositary receipts will not necessarily be denominated in the same currency as their underlying securities. In general, ADRs, in registered form, are designed for use in the U.S. securities markets, and EDRs, in bearer form, are designed for use in European securities markets. GDRs are tradable both in the United States and in Europe and are designed for use throughout the world. The Fund may invest in depositary receipts through “sponsored” or “unsponsored” facilities. A sponsored facility is established jointly by the issuer of the underlying security and a depositary, whereas a depositary may establish an unsponsored facility without participation by the issuer of the deposited security. Holders of unsponsored depositary receipts generally bear all the costs of such facilities and the depositary of an unsponsored facility frequently is under no obligation to distribute interestholder communications received from the issuer of the deposited security or to pass through voting rights to the holders of such receipts in respect of the deposited securities. The issuers of unsponsored depositary receipts are not obligated to disclose material information in the United States, and, therefore, there may be limited information available regarding such issuers and/or limited correlation between available information and the market value of the depositary receipts.

Investing in foreign securities is subject to certain risks. For example, foreign markets can be extremely volatile. Fluctuations in currency exchange rates also may impact the value of foreign securities denominated in foreign currencies or U.S. dollars, without a change in the intrinsic value of those securities. Additionally, the U.S. dollar value of a foreign security tends to decrease when the value of the U.S. dollar rises against the foreign currency in

21

Table of Contents

which the security is denominated and tends to increase when the value of the U.S. dollar falls against such currency. The Fund may attempt to minimize the risk from adverse changes in the relationship between the U.S. dollar and foreign currencies by purchasing and selling forward foreign currency exchange contracts and foreign currency futures contracts and related options. Foreign securities may be less liquid than domestic securities so that the Fund may, at times, be unable to sell foreign securities at desirable prices. Brokerage commissions, custodial fees and other fees also are generally higher for foreign securities. 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 potentially confiscatory withholding or other taxes, which would reduce the Fund’s return on these securities. Other risks include: possible delays in the settlement of transactions or in the notification of income; generally less publicly available information about companies; adverse impact of political, social or diplomatic events; possible seizure, expropriation or nationalization of a company or its assets; possible imposition of currency exchange controls; and that foreign companies generally are not subject to accounting, auditing and financial reporting standards comparable to those mandated for domestic companies.

Risks associated with investments in foreign securities are increased with respect to investments in emerging market countries. Political and economic structures in many emerging market countries, especially those in Eastern Europe, the Pacific Basin and the Far East, are undergoing significant evolutionary changes and rapid development, and may lack the social, political and economic stability of more developed countries. Investing in emerging market securities also involves risks beyond the risks applicable to foreign investments. For example, some emerging market countries may have fixed or managed currencies that are not free-floating against the U.S. dollar. Further, certain currencies may not be traded internationally, and some countries with emerging securities markets have sustained long periods of very high inflation or rapid fluctuation in inflation rates which can have negative effects on a country’s economy and securities markets.

Illiquid Securities

Illiquid securities are defined by the Fund consistent with SEC staff’s current guidance and interpretations which provide that an illiquid security is an asset which may not be sold or disposed of in the ordinary course of business within seven days at approximately the value at which the Fund has valued the investment on its books. Some securities, such as those not registered under U.S. securities laws, cannot be sold in public transactions. Subject to its investment policies, the Fund may invest in illiquid investments and may invest in certain restricted securities that are deemed to be illiquid securities.

Initial Public Offerings

The Fund may invest in initial public offerings (IPOs) of common stock or other primary or secondary syndicated offerings of equity or debt securities issued by a corporate issuer. Fixed income funds frequently invest in these types of offerings of debt securities. A purchase of IPO securities often involves higher transaction costs than those associated with the purchase of securities already traded on exchanges or markets. IPO securities are subject to market risk and liquidity risk. The market value of recently issued IPO securities may fluctuate considerably due to factors such as the absence of a prior public market, unseasoned trading and speculation, a potentially small number of securities available for trading, limited information about the issuer, and other factors. The Fund may hold IPO securities for a period of time, or may sell them soon after the purchase. Investments in IPOs could have a magnified impact — either positive or negative — on the Fund’s performance while the Fund’s assets are relatively small. The impact of an IPO on the Fund’s performance may tend to diminish as the Fund’s assets grow. In circumstances when investments in IPOs make a significant contribution to the Fund’s performance, there can be no assurance that similar contributions from IPOs will continue in the future.

Investments in Other Investment Companies

Investing in other investment companies may be a means by which the Fund seeks to achieve its investment objective. The Fund may invest in securities issued by other investment companies within the limits prescribed by the 1940 Act, the rules and regulations thereunder and any exemptive orders currently or in the future obtained by the Fund from the SEC.

Except with respect to funds structured as funds-of-funds or so-called master/feeder funds, the 1940 Act generally requires that a fund limit its investments in another investment company or series thereof so that, as determined at the time a securities purchase is made: (i) no more than 5% of the value of its total assets will be

22

Table of Contents

invested in the securities of any one investment company; (ii) no more than 10% of the value of its total assets will be invested in the aggregate in securities of other investment companies; and (iii) no more than 3% of the outstanding voting stock of any one investment company or series thereof will be owned by a fund or by companies controlled by the Fund. Such other investment companies may include ETFs, which are shares of publicly traded unit investment trusts, open-end funds or depositary receipts that seek to track the performance of specific indexes or companies in related industries.

Investing in other investment companies is subject to certain risks. Although a fund may derive certain advantages from being able to invest in shares of other investment companies, such as to be fully invested, there may be potential disadvantages. Investing in other investment companies may result in higher fees and expenses for a fund and its shareholders. A shareholder may be charged fees not only on fund shares held directly but also on the investment company shares that a fund purchases.

In addition, investing in ETFs is subject to certain other risks. ETFs generally are subject to the same risks as the underlying securities the ETFs are designed to track as well as to the risks of the specific sector or industry to which the ETF relates. ETFs also are subject to the risk that their prices may not totally correlate to the prices of the underlying securities the ETFs are designed to track and the risk of possible trading halts due to market conditions or for other reasons.

Under the 1940 Act and rules and regulations thereunder, the Fund may purchase shares of other affiliated Columbia Funds, including the Money Market Funds, subject to certain conditions. Investing in affiliated funds may present certain actual or potential conflicts of interest. For more information about such actual and potential conflicts of interest, see Investment Advisory and Other Services—Other Roles and Relationships of Bank of America and its Affiliates—Certain Conflicts of Interest.

Money Market Instruments

Money market instruments are high-quality, short-term debt obligations, which include: (i) bank obligations, including certificates of deposit, time deposits and bankers’ acceptances; (ii) funding agreements; (iii) repurchase agreements; (iv) obligations of the United States, foreign countries and supranational entities, and each of their subdivisions, agencies and instrumentalities; (v) certain corporate debt securities, such as commercial paper, short- term corporate obligations and extendible commercial notes; (vi) participation interests; and (vii) municipal securities. Money market instruments may be structured as fixed-, variable- or floating-rate obligations and may be privately placed or publicly offered. See Permissible Fund Investments — Variable- and Floating-Rate Obligations and Permissible Fund Investments — Private Placement and Other Restricted Securities for more information.

Investing in money market instruments is subject to certain risks. Money market instruments (other than certain U.S. Government obligations) are not backed or insured by the U.S. Government, its agencies or its instrumentalities. Accordingly, only the creditworthiness of an issuer, or guarantees of that issuer, support such instruments.

Mortgage-Backed Securities

Mortgage-backed securities are a type of asset-backed security and represent interests in, or debt instruments backed by, pools of underlying mortgages. In some cases, these underlying mortgages may be insured or guaranteed by the U.S. Government or its agencies. Mortgage-backed securities entitle the security holders to receive distributions that are tied to the payments made on the underlying mortgage collateral (less fees paid to the originator, servicer, or other parties, and fees paid for credit enhancement), so that the payments made on the underlying mortgage collateral effectively pass through to such security holders. Mortgage-backed securities are created when mortgage originators (or mortgage loan sellers who have purchased mortgage loans from mortgage loan originators) sell the underlying mortgages to a special purpose entity in a process called a securitization. The special purpose entity issues securities that are backed by the payments on the underlying mortgage loans, and have a minimum denomination and specific term. Mortgage-backed securities may be structured as fixed-, variable- or floating-rate obligations or as zero-coupon, pay-in-kind and step-coupon securities and may be privately placed or publicly offered. See Permissible Fund Investments — Variable- and Floating-Rate Obligations , Permissible Fund Investments — Zero-Coupon, Pay-in-Kind and Step-Coupon Securities and Permissible Fund Investments — Private Placement and Other Restricted Securities for more information.

Mortgage-backed securities may be issued or guaranteed by GNMA (also known as Ginnie Mae), FNMA (also known as Fannie Mae), or FHLMC (also known as Freddie Mac), but also may be issued or guaranteed by other issuers, including private companies. GNMA is a government-owned corporation that is an agency of the U.S.

Department of Housing and Urban Development. It guarantees, with the full faith and credit of the United States, full and timely payment of all monthly principal and interest on its mortgage-backed securities. Until recently, FNMA and FHLMC were government-sponsored corporations owned entirely by private stockholders. Both issue mortgage-related securities that contain guarantees as to timely payment of interest and principal but that are not backed by the full faith and credit of the U.S. government. The value of the companies’ securities fell sharply in 2008 due to concerns that the firms did not have sufficient capital to offset losses. In mid-2008, the U.S. Treasury was authorized to increase the size of home loans that FNMA and FHLMC could purchase in certain residential areas and, until 2009, to lend FNMA and FHLMC emergency funds and to purchase the companies’ stock. More recently, in September 2008, the U.S. Treasury announced that FNMA and FHLMC had been placed in conservatorship by the Federal Housing Finance Agency (FHFA), a newly created independent regulator. In addition to placing the companies in conservatorship, the U.S. Treasury announced three additional steps that it intended to take with respect to FNMA and FHLMC. First, the U.S. Treasury has entered into “Preferred Stock Purchase Agreements” (PSPAs) under which, if the FHFA determines that FNMA’s or FHLMC’s liabilities have exceeded its assets under generally accepted accounting principles, the U.S. Treasury will contribute cash capital to the company in an amount equal to the difference between liabilities and assets. The PSPAs are designed to provide protection to the senior and subordinated debt and the mortgage-backed securities issued by FNMA and FHLMC. Second, the U.S. Treasury established a new secured lending credit facility that is available to FNMA and FHLMC until December 2009. Third, the U.S. Treasury initiated a temporary program to purchase FNMA and FHLMC mortgage-backed securities, which is expected to continue until December 2009. No assurance can be given that the U.S. Treasury initiatives discussed above with respect to the debt and mortgage-backed securities issued by FNMA and FHLMC will be successful.

CMOs are debt obligations issued by special-purpose trusts, collateralized by underlying mortgage assets. Principal prepayments on underlying mortgage assets may cause the CMOs to be retired substantially earlier than their stated maturities or final distribution dates, resulting in a loss of all or part of the premium if any has been paid. Interest is paid or accrues on all classes of the CMOs on a periodic basis. The principal and interest payments on the underlying mortgage assets may be allocated among the various classes of CMOs in several ways. Typically, payments of principal, including any prepayments, on the underlying mortgage assets are applied to the classes in the order of their respective stated maturities or final distribution dates, so that no payment of principal is made on CMOs of a class until all CMOs of other classes having earlier stated maturities or final distribution dates have been paid in full.

REMICs are entities that own mortgages and elect REMIC status under the Code and, like CMOs, issue debt obligations collateralized by underlying mortgage assets that have characteristics similar to those issued by CMOs.

Investing in mortgage-backed securities is subject to certain risks, including, among others, prepayment, market and credit risks. Prepayment risk reflects the risk that borrowers may prepay their mortgages more quickly than expected, which may affect the security’s average maturity and rate of return. Whether or not a mortgage loan is prepaid is almost entirely controlled by the borrower. Borrowers are most likely to exercise prepayment options at the time when it is least advantageous to investors, generally prepaying mortgages as interest rates fall, and slowing payments as interest rates rise. Besides the effect of prevailing interest rates, the rate of prepayment and refinancing of mortgages also may be affected by home value appreciation, ease of the refinancing process and local economic conditions, among other factors. Market risk reflects the risk that the price of a security may fluctuate over time. The price of mortgage-backed securities can be particularly sensitive to prevailing interest rates, the length of time the security is expected to be outstanding and the liquidity of the issue. In a period of unstable interest rates, there may be decreased demand for certain types of mortgage-backed securities, which in turn may decrease their value. Credit risk reflects the risk that a holder of mortgage-backed securities may not receive all or part of its principal because the issuer, any credit enhancer and/or the underlying mortgage borrower has defaulted on its obligations. Credit risk is increased for mortgage-backed securities that are backed by mortgages to so-called subprime borrowers (who may pose a greater risk of defaulting on their loans) or that are subordinated to another security (i.e., if the holder of a mortgage-backed security is entitled to receive payments only after payment obligations to holders of the other security are satisfied). The more deeply subordinated the security, the greater the credit risk associated with the security will be. Mortgage-backed securities issued by private issuers, whether or not such obligations are subject to guarantees by the private issuer, may entail greater risk than mortgage-backed securities guaranteed by the U.S. Government. The performance of mortgage-backed securities issued by private issuers generally depends on the financial health of those institutions.

Participation Interests

Participation interests (also called pass-through certificates or securities) represent an interest in a pool of debt obligations, such as municipal bonds or notes, that have been “packaged” by an intermediary, such as a bank or broker/dealer. Participation interests typically are issued by partnerships or trusts through which the Fund receives principal and interest payments that are passed through to the holder of the participation interest from the payments made on the underlying debt obligations. The purchaser of a participation interest receives an undivided interest in the underlying debt obligations. The issuers of the underlying debt obligations make interest and principal payments to the intermediary, as an initial purchaser, which are passed through to purchasers in the secondary market, such as the Fund. Mortgage-backed securities are a common type of participation interest. Participation interests may be structured as fixed-, variable- or floating-rate obligations or as zero-coupon, pay- in-kind and step-coupon securities and may be privately placed or publicly offered. See Permissible Fund Investments — Variable- and Floating-Rate Obligations , Permissible Fund Investments — Zero-Coupon, Pay-in-Kind and Step-Coupon Securities and Permissible Fund Investments — Private Placement and Other Restricted Securities for more information.

Loan participations also are a type of participation interest. Loan participations are interests in loans that are administered by a lending bank or agent for a syndicate of lending banks and sold by the bank or syndicate members.

Investing in participation interests is subject to certain risks. Participation interests generally are subject to the credit risk associated with the underlying borrowers. If the underlying borrower defaults, the 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 of the borrower. The Fund also may be deemed a creditor of the lending bank or syndicate members and be subject to the risk that the lending bank or syndicate members may become insolvent.

Private Placement and Other Restricted Securities

Private placement securities are securities that have been privately placed and are not registered under the 1933 Act. They are eligible for sale only to certain eligible investors. Private placements often may offer attractive opportunities for investment not otherwise available on the open market. Private placement and other “restricted” securities often cannot be sold to the public without registration under the 1933 Act or the availability of an exemption from registration (such as Rules 144 or 144A), or they are “not readily marketable” because they are subject to other legal or contractual delays in or restrictions on resale. Asset-backed securities, common stock, convertible securities, corporate debt securities, foreign securities, low and below investment grade securities, money market instruments, mortgage-backed securities, municipal securities, participation interests, preferred stock and other types of equity and debt instruments may be privately placed or restricted securities.

Private placements typically may be sold only to qualified institutional buyers (or, in the case of the initial sale of certain securities, such as those issued in collateralized debt obligations or collateralized loan obligations, to accredited investors (as defined in Rule 501(a) under the 1933 Act), or in a privately negotiated transaction or to a limited number of purchasers, or in limited quantities after they have been held for a specified period of time and other conditions are met pursuant to an exemption from registration.

Investing in private placement and other restricted securities is subject to certain risks. Private placements may be considered illiquid securities. Private placements typically are subject to restrictions on resale as a matter of contract or under federal securities laws. Because there may be relatively few potential purchasers for such securities, especially under adverse market or economic conditions or in the event of adverse changes in the financial condition of the issuer, the Fund could find it more difficult to sell such securities when it may be advisable to do so or it may be able to sell such securities only at prices lower than if such securities were more widely held. At times, it also may be more difficult to determine the fair value of such securities for purposes of computing the Fund’s net asset value due to the absence of a trading market.

Repurchase Agreements

Repurchase agreements are agreements under which the Fund acquires a security for a relatively short period of time subject to the obligation of a seller to repurchase and the Fund to resell such security at a fixed time and price (representing the Fund’s cost plus interest). Repurchase agreements also may be viewed as loans made by the Fund that are collateralized by the securities subject to repurchase. The Fund typically will enter into repurchase agreements only with commercial banks, registered broker/dealers and the Fixed Income Clearing Corporation. Such transactions are monitored to ensure that the value of the underlying securities will be at least equal at all times to the total amount of the repurchase obligation, including any accrued interest.

25

Table of Contents

Repurchase agreements generally are subject to counterparty risk. If a counterparty defaults, the Fund could realize a loss on the sale of the underlying security to the extent that the proceeds of the sale are less than the resale price provided in the repurchase agreement including interest. In the event that a counterparty fails to perform because it is insolvent or otherwise subject to insolvency proceedings against it, the Fund’s right to take possession of the underlying securities would be subject to applicable insolvency law and procedure, including an automatic stay (which would preclude immediate enforcement of the Fund’s rights) and exemptions thereto (which would permit the Fund to take possession of the underlying securities or to void a repurchase agreement altogether). Since it is possible that an exemption from the automatic stay would not be available, the Fund might be prevented from immediately enforcing its rights against the counterparty. Accordingly, if a counterparty becomes insolvent or otherwise subject to insolvency proceedings against it, the Fund may incur delays in or be prevented from liquidating the underlying securities and could experience losses, including the possible decline in value of the underlying securities during the period in which the Fund seeks to enforce its rights thereto, possible subnormal levels of income or lack of access to income during such time, as well as the costs incurred in enforcing the Fund’s rights. For example, if the Fund enters into a repurchase agreement with a broker that becomes insolvent, it is possible for the Securities Investor Protection Corporation (SIPC) to institute a liquidation proceeding in federal court against the broker counterparty which could lead to a foreclosure by SIPC of the underlying securities or SIPC may stay, or preclude, the Fund’s ability under contract to terminate the repurchase agreement.

U.S. Government and Related Obligations

U.S. Government obligations include U.S. Treasury obligations and securities issued or guaranteed by various agencies of the U.S. Government or by various instrumentalities which have been established or sponsored by the U.S. Government. U.S. Treasury obligations and securities issued or guaranteed by various agencies of the U.S. Government differ in their interest rates, maturities and time of issuance, as well as with respect to whether they are guaranteed by the U.S. Government. U.S. Government and related obligations may be structured as fixed-, variable- or floating-rate obligations. See Permissible Fund Investments — Variable- and Floating-Rate Obligations for more information.

U.S. Government obligations also include senior unsecured debt securities issued between October 14, 2008 and June 30, 2009 by eligible issuers (including U.S. depository institutions insured by the FDIC (and certain affiliates), U.S. bank holding companies and certain U.S. savings and loan holding companies) that are guaranteed by the FDIC under its Temporary Liquidity Guarantee Program (the “TLGP”). The FDIC’s guarantee under the TLGP will expire upon the earlier of (i) maturity of such security or (ii) June 30, 2012. It is the view of the FDIC and the staff of the Securities and Exchange Commission that any debt security that is guaranteed by the FDIC under the TLGP and that has a maturity that ends on or before June 30, 2012 would be a security exempt from registration under Section 3(a)(2) of the Securities Act of 1933 because such security would be fully and unconditionally guaranteed by the FDIC. Investing in securities guaranteed under the TLGP is subject to certain risks. Given that there is no track record for securities guaranteed under the TLGP, it is uncertain how such securities will trade in relation to treasury and government agency securities in terms of yield spread and the volatility of such spread and it is uncertain how such securities will trade in the secondary market and whether that market will be liquid or illiquid. The TLGP is a new program that is subject to change. In order to collect from the FDIC under the TLGP, a claims process must be followed. Failure to follow the claims process could result in a loss to the right to payment under the guarantee. In addition, guarantee payments by the FDIC under the TLGP may be delayed.

Investing in U.S. Government and related obligations is subject to certain risks. While U.S. Treasury obligations are backed by the “full faith and credit” of the U.S. Government, securities issued or guaranteed by federal agencies and U.S. Government-sponsored instrumentalities may or may not be backed by the full faith and credit of the U.S. Government. These 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 credit risk than securities issued or guaranteed by the U.S. Treasury. Obligations of U.S. Government agencies, authorities, instrumentalities and sponsored enterprises historically have involved limited risk of loss of principal if held to maturity. However, no assurance can be given that the U.S. Government would provide financial support to any of these entities if it is not obligated to do so by law.

Variable- and Floating-Rate Obligations

Variable- and floating-rate obligations provide for periodic adjustments in the interest rate and, under certain circumstances, varying principal amounts. Unlike a fixed interest rate, a variable, or floating, rate is one that rises and declines based on the movement of an underlying index of interest rates and may pay interest at rates that are adjusted periodically according to a specified formula. Asset-backed securities, bank obligations, convertible securities, corporate debt securities, foreign securities, low and below investment grade securities, money market instruments, mortgage-backed securities, municipal securities, participation interests, stripped securities, U.S. Government and related obligations and other types of debt instruments may be structured as variable- and floating-rate obligations.

Investing in variable- and floating-rate obligations is subject to certain risks. Variable- and floating-rate obligations may involve direct lending arrangements between the purchaser and the issuer and there may be no active secondary market, making it difficult to resell such obligations to a third party. Variable- and floating-rate obligations also may be subject to interest rate and credit risks. Changes in interest rates can affect the rate of return on such obligations. If an issuer of a variable- or floating-rate obligation defaults, the Fund could sustain a loss to the extent of such default.

When-Issued, Delayed Delivery and Forward Commitment Transactions

When-issued, delayed delivery and forward commitment transactions involve the purchase or sale of securities by the Fund, with payment and delivery taking place in the future. When engaging in when-issued, delayed delivery and forward commitment transactions, the Fund typically will hold cash or liquid securities in a segregated account in an amount equal to or greater than the purchase price. The payment obligation and, if applicable, the interest rate that will be received on the securities, are fixed at the time that the Fund agrees to purchase the securities. The Fund generally will enter into when-issued, delayed delivery and forward commitment transactions only with the intention of completing such transactions. However, the Advisor may determine not to complete a transaction if it deems it appropriate. In such cases, the Fund may realize short-term gains or losses.

When-issued, delayed delivery and forward commitment transactions involve the risks that the securities purchased may fall in value by the time they actually are issued or that the other party may fail to honor the contract terms. The Fund that invests in delayed delivery securities may rely on a third party to complete the transaction. Failure by a third party to deliver a security purchased on a delayed delivery basis may result in a financial loss to the Fund or the loss of an opportunity to make an alternative investment.

Zero-Coupon, Pay-in-Kind and Step-Coupon Securities

Zero-coupon, pay-in-kind and step-coupon securities are types of debt instruments that do not necessarily make payments of interest in fixed amounts or at fixed intervals. Asset-backed securities, convertible securities, corporate debt securities, foreign securities, low and below investment grade securities, mortgage-backed securities, municipal securities, participation interests, stripped securities, U.S. Government and related obligations and other types of debt instruments may be structured as zero-coupon, pay-in-kind and step-coupon securities.

Zero-coupon securities do not pay interest on a current basis but instead accrue interest over the life of the security. These securities include, among others, zero-coupon bonds, which either may be issued at a discount by a corporation or government entity or may be created by a brokerage firm when it strips the coupons from a bond or note and then sells the bond or note and the coupon separately. This technique is used frequently with U.S. Treasury bonds, and zero-coupon securities are marketed under such names as CATS (Certificate of Accrual on Treasury Securities), TIGERs (Treasury Investor Growth Receipts) or STRIPS (Separate Trading of Registered Interest and Principal of Securities). Zero-coupon bonds also are issued by municipalities. Buying a municipal zero-coupon bond frees its purchaser of the obligation to pay regular federal income tax on imputed interest, since the interest is exempt for regular federal income tax purposes. Zero-coupon certificates of deposit and zero- coupon mortgages are generally structured in the same fashion as zero-coupon bonds; the certificate of deposit holder or mortgage holder receives face value at maturity and no payments until then.

Pay-in-kind securities normally give the issuer an option to pay cash at a coupon payment date or to give the holder of the security a similar security with the same coupon rate and a face value equal to the amount of the coupon payment that would have been made.

Step-coupon securities trade at a discount from their face value and pay coupon interest. The coupon rate is paid according to a schedule for a series of periods, typically lower for an initial period and then increasing to a higher coupon rate thereafter. The discount from the face amount or par value depends on the time remaining until cash payments begin, prevailing interest rates, liquidity of the security and the perceived credit quality of the issue.

27

Table of Contents

Zero-coupon, step-coupon and pay-in-kind securities holders generally have substantially all the rights and privileges of holders of the underlying coupon obligations or principal obligations. Holders of these securities have the right upon default on the underlying coupon obligations or principal obligations to proceed directly and individually against the issuer and are not required to act in concert with other holders of such securities.

Investing in zero-coupon, pay-in-kind and step-coupon securities is subject to certain risks, including that market prices of zero-coupon, pay-in-kind and step-coupon securities generally are more volatile than the prices of securities that pay interest periodically and in cash, and are likely to respond to changes in interest rates to a greater degree than other types of debt securities.

Because zero-coupon securities bear no interest, they are volatile. Since zero-coupon bondholders do not receive interest payments, zero-coupon securities fall more dramatically than bonds paying interest on a current basis when interest rates rise. However, when interest rates fall, zero-coupon securities rise more rapidly in value than interest paying bonds.

Borrowings

The Fund has a fundamental policy with respect to borrowing that can be found under the heading About the Fund’s Investments — Fundamental and Non-Fundamental Investment Policies. Specifically, the Fund may not borrow money or issue senior securities except to the extent permitted by the 1940 Act, the rules and regulations thereunder and any exemptive relief obtained by the Fund. In general, pursuant to the 1940 Act, the Fund may borrow money only from banks in an amount not exceeding 33 ¹ /3% of its total assets (including the amount borrowed) less liabilities (other than borrowings). Any borrowings that come to exceed this amount must be reduced within three days (not including Sundays and holidays) to the extent necessary to comply with the 33 ¹ /3% limitation.

The Fund participates in a committed line of credit (Line of Credit). Any advance under the Line of Credit is contemplated primarily for temporary or emergency purposes, including the meeting of redemption requests that otherwise might require the untimely sale of portfolio securities.

Pursuant to an exemptive order from the SEC, the Fund may, subject to certain conditions, borrow money from other funds in the Columbia Funds Family for temporary emergency purposes in order to facilitate redemption requests, or for other purposes consistent with Fund investment policies and restrictions. All loans are set at an interest rate between the rates charged on overnight repurchase agreements and short-term bank loans.

Short Sales

The Fund may sometimes sell securities short when it owns an equal amount of such securities as those securities sold short. This is a technique known as selling short “against the box.” If the Fund makes a short sale “against the box,” it would not immediately deliver the securities sold and would not receive the proceeds from the sale. The seller is said to have a short position in the securities sold until it delivers the securities sold, at which time it receives the proceeds of the sale. To secure its obligation to deliver securities sold short, the Fund will deposit in escrow in a separate account with the custodian an equal amount of the securities sold short or securities convertible into or exchangeable for such securities. The Fund can close out its short position by purchasing and delivering an equal amount of the securities sold short, rather than by delivering securities already held by the Fund, because the Fund might want to continue to receive interest and dividend payments on securities in its portfolio that are convertible into the securities sold short.

Short sales “against the box” entail many of the same risks and considerations described above regarding short sales not “against the box.” However, when the Fund sells short “against the box” it typically limits the amount of securities that it has leveraged. The Fund’s decision to make a short sale “against the box” may be a technique to hedge against market risks when the Advisor believes that the price of a security may decline, causing a decline in the value of a security owned by the Fund or a security convertible into or exchangeable for such security. In such case, any future losses in the Fund’s long position would be reduced by a gain in the short position. The extent to which such gains or losses in the long position are reduced will depend upon the amount of securities sold short

28

Table of Contents

relative to the amount of the securities the Fund owns, either directly or indirectly, and, in the case where the Fund owns convertible securities, changes in the investment values or conversion premiums of such securities. Short sales may have adverse tax consequences to the Fund and its shareholders.

Subject to its fundamental and non-fundamental investment policies, the Fund may engage in short sales that are not “against the box,” which are sales by the Fund of securities or commodity futures contracts that it does not own in hopes of purchasing the same security at a later date at a lower price. The technique is also used to protect a profit in a long-term position in a security or commodity futures contract. To make delivery to the buyer, the Fund must borrow or purchase the security. If borrowed, the Fund is then obligated to replace the security borrowed from the third party, so the Fund must purchase the security at the market price at a later 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 of the short sale plus any premiums and interest paid to the third party. (Until the security is replaced, the Fund is required to pay to the lender amounts equal to any dividends or interest which accrue during the period of the loan. To borrow the security, the Fund also may be required to pay a premium, which would increase the cost of the security sold. The proceeds of the short sale will be retained by the broker, to the extent necessary to meet the margin requirements, until the short position is closed out.)

Short sales by the Fund that are not made “against the box” create opportunities to increase the Fund’s return but, at the same time, involve specific risk considerations and may be considered a speculative technique. Because the Fund in effect profits from a decline in the price of the securities sold short without the need to invest the full purchase price of the securities on the date of the short sale, the Fund’s NAV per share tends to increase more when the securities it has sold short decrease in value, and to decrease more when the securities it has sold short increase in value, than if it had not engaged in such short sales. The amount of any gain will be decreased, and the amount of any loss increased, by the amount of any premium, dividends or interest the Fund may be required to pay in connection with the short sale. Short sales could potentially involve unlimited loss, as the market price of securities sold short may continually increase, although the Fund can mitigate any such losses by replacing the securities sold short. Under adverse market conditions, the Fund might have difficulty purchasing securities to meet its short sale delivery obligations, and might have to sell portfolio securities to raise the capital necessary to meet its short sale obligations at a time when fundamental investment considerations would not favor such sales. There is also the risk that the third party to the short sale may fail to honor its contract terms, causing a loss to the Fund.

The Fund’s successful use of short sales also will be subject to the ability of the Advisor to predict movements in the directions of the relevant market. The Fund therefore bears the risk that the Advisor will incorrectly predict future price directions. In addition, if the Fund sells a security short, and that security’s price goes up, the Fund will have to make up the margin on its open position (i.e., purchase more securities on the market to cover the position). It may be unable to do so and thus its position may not be closed out. There can be no assurance that the Fund will not incur significant losses in such a case.

In the view of the SEC, a short sale involves the creation of a “senior security” as such term is defined in the 1940 Act, unless the sale is “against the box” and the securities sold short are placed in a segregated account (not with the broker), or unless the Fund’s obligation to deliver the securities sold short is “covered” by placing in a segregated account (not with the broker) cash, U.S. Government securities or other liquid debt or equity securities in an amount equal to the difference between the market value of the securities sold short at the time of the short sale and any such collateral required to be deposited with a broker in connection with the sale (not including the proceeds from the short sale), which difference is adjusted daily for changes in the value of the securities sold short. The total value of the cash, U.S. Government securities or other liquid debt or equity securities deposited with the broker and otherwise segregated may not at any time be less than the market value of the securities sold short at the time of the short sale.

Lending Securities

Securities lending refers to the lending of the Fund’s portfolio securities. Subject to its investment policies described above and in the prospectuses, the Fund may make secured loans of its portfolio securities to broker/dealers and other institutional investors. Securities loans by the Fund are made pursuant to agreements that require that loans be secured continuously by collateral in cash. The Fund retains all or a portion of the income received on investment of cash collateral. A borrower will pay to the Fund an amount equal to any dividends or interest received on securities loaned, but the borrower typically will receive a portion of the income earned on

29

Table of Contents

investments of cash collateral. Although voting rights, or rights to consent, with respect to loaned securities pass to a borrower, the Fund retains the right to call the loans at any time on reasonable notice, and may do so in order to vote upon matters affecting, or to sell, the loaned securities.

The Fund typically invests the cash collateral it receives in connection with its securities lending program directly or indirectly in high quality, short-term investments. The Fund may invest some or all of the cash collateral in one or more pooled investment vehicles, including, among other vehicles, money market funds managed by the Fund’s securities lending agent or its affiliates. The securities lending agent shares in any income resulting from the investment of cash collateral, and an affiliate of the securities lending agent receives asset-based fees for the management of the pooled investment vehicles, which may create a conflict of interest between the securities lending agent (or its affiliate) and the Fund with respect to the management of the cash collateral.

Engaging in securities lending is subject to certain risks, including counterparty risk, which is the risk that the counterparty to a transaction could default. There also is a risk of possible delay in the recovery of loaned securities or possible loss of rights in the collateral if a borrower fails financially.

Portfolio Turnover

A change in the securities held by the Fund is known as “portfolio turnover.” High portfolio turnover ( e.g., over 100%) involves correspondingly greater expenses to the Fund, including brokerage commissions or dealer mark-ups and other transaction costs on the sale of securities and reinvestments in other securities. Such sales may also result in adverse tax consequences to the Fund’s shareholders. The trading costs and tax effects associated with portfolio turnover may adversely affect the Fund’s performance.

For the Fund’s portfolio turnover rate, see the Financial Highlights section in the prospectus for the Fund.

Disclosure of Portfolio Information

The Board has adopted policies and procedures with respect to the disclosure of the Fund’s portfolio holdings. These policies and procedures are designed to ensure that disclosure of information regarding the Fund’s portfolio securities is in the best interests of Fund shareholders and to address conflicts between the interests of Fund shareholders, on the one hand, and those of the Advisor, the Distributor or any affiliated person of the Fund, on the other. These policies and procedures provide that Fund portfolio holdings information generally may not be disclosed to any party prior to the earlier of: (i) the business day next following the posting of such information on the Fund’s website, if applicable, or (ii) the time the Fund discloses the information in a publicly available SEC filing required to include such information. Certain limited exceptions that have been approved consistent with the policies and procedures are described below. The Board is updated as needed regarding compliance with these policies and procedures. The policies and procedures prohibit the Advisor 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 and procedures apply to all categories of Columbia Funds and include some variations tailored to the different categories of Columbia Funds. Accordingly, some of the provisions described below do not apply to the Fund covered by this SAI. The Advisor also has adopted policies and procedures to monitor for compliance with these portfolio holdings disclosure policies and procedures.

Public Disclosures

The Fund’s portfolio holdings are currently disclosed to the public through required filings with the SEC and on the Fund’s website. This information is available on the Fund’s website as described below.

30

Table of Contents

Certain Columbia Funds also disclose their largest holdings, as a percent of the market values of the Columbia Funds’ portfolios, as of a month-end on their website, generally within 15 calendar days after such month-end. In general, the equity Columbia Funds post their largest 10-15 holdings and certain fixed income Columbia Funds post their largest 5-15 holdings (by security or issuer).

The Advisor may also disclose more current portfolio holdings information as of specified dates on the Fund’s website.

The scope of the information that is made available on the Fund’s website pursuant to the Fund’s policies relating to the Fund’s portfolio may change from time to time without prior notice.

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 Form N-CSR and N-Q filings on the SEC’s website at www.sec.gov, a link to which is provided on the Fund’s website. In addition, the Fund’s Form 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 800.SEC.0330 for information about the SEC’s website or the operation of the public reference room.

With respect to variable insurance trusts in the Columbia Funds Family, holdings information is disclosed no earlier than the time such information is filed in a publicly available SEC filing required to include such information.

The Fund, the Advisor and their affiliates may include portfolio holdings information that already has been made public through a website 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 business day after the date the information is disclosed publicly on the Fund’s website or no earlier than the time the Fund files such information in a publicly available SEC filing required to include such information.

Other Disclosures

The Fund’s policies and procedures provide that no disclosures of the Columbia Funds’ portfolio holdings may be made prior to the portfolio holdings information being made public unless (i) the Fund has a legitimate business purpose for making such disclosure, (ii) the Fund’s President authorizes such non-public disclosure of information, and (iii) the party receiving the non-public information enters into an appropriate confidentiality agreement or is otherwise subject to a confidentiality obligation.

In determining the existence of a legitimate business purpose for making portfolio disclosures, the following factors, among others, are considered: (i) any prior disclosure must be consistent with the anti-fraud provisions of the federal securities laws and the fiduciary duties of the Advisor; (ii) any conflicts of interest between the interests of Fund shareholders, on the one hand, and those of the Advisor, the Distributor or any affiliated person of the Fund, on the other; and (iii) any prior disclosure to a third party, although subject to a confidentiality agreement, would not make conduct lawful that otherwise is unlawful.

In addition, the Fund periodically discloses its portfolio information on a confidential basis to various service providers that require such information to assist the Fund with its day-to-day business affairs. In addition to the Advisor and its affiliates, these service providers include the Fund’s sub-advisor(s) (if any), the Fund’s custodian, sub-custodian, independent registered public accounting firm, legal counsel, financial printers, proxy solicitor and proxy voting service provider, as well as ratings agencies that maintain ratings on certain Funds. 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.
