FUNDAMENTAL AND NON-FUNDAMENTAL INVESTMENT POLICIES

The following discussion of “fundamental” and “non-fundamental” investment policies and limitations for each Fund supplements the discussion of investment policies in the Funds’ prospectuses. A fundamental policy may be changed only with Board and shareholder approval. A non-fundamental policy may be changed by the Board and does not require shareholder approval, but may require notice to shareholders in certain instances.

Unless otherwise noted, whenever an investment policy or limitation states a maximum percentage of a Fund’s assets that may be invested in any security or other asset, or sets forth a policy regarding an investment standard, compliance with such percentage limitation or standard will be determined solely at the time of the Fund’s acquisition of such security or asset.

Fundamental Investment Policies

The 1940 Act provides that a “vote of a majority of the outstanding voting securities” means the affirmative vote of the lesser of (1) more than 50% of the outstanding shares of a Fund, or (2) 67% or more of the shares present at a meeting if more than 50% of the outstanding shares are represented at the meeting in person or by proxy. The following fundamental investment policies cannot be changed without such a vote.

Except as noted, each Fund may not, as a matter of fundamental policy:

Non-Fundamental Investment Policies

The following non-fundamental investment restrictions apply to each ETF and may be changed with respect to an ETF by a vote of a majority of the Board.

No ETF may:

If a percentage limitation is satisfied at the time of investment, a later increase or decrease in such percentage resulting from a change in the value of an ETF’s investments will not constitute a violation of such limitation. Thus, an ETF may continue to hold a security even though it causes the ETF to exceed a percentage limitation because of fluctuation in the value of the ETF’s assets, except that any borrowing by an ETF that exceeds the fundamental investment limitations stated above must be reduced to meet such limitations within the period required by the Investment Company Act or the relevant rules, regulations or interpretations thereunder.

ABOUT THE FUNDS’ INVESTMENTS

The investment objectives, principal investment strategies and related principal risks for each Fund are discussed in each Fund’s prospectuses.

Each 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. Unless otherwise indicated in the prospectus or this SAI, the investment objective and policies of a Fund may be changed without shareholder approval.

To the extent that a type of security identified in the table below for a Fund is not described in the Fund’s prospectuses (or as a sub-category of such security type in this SAI), the Fund generally invests in such security type as part of its non-principal investment strategies.

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

Certain Investment Activity Limits. The overall investment and other activities of the Investment Manager and its affiliates may limit the investment opportunities for each Fund in certain markets where limitations are imposed by regulators upon the amount of investment by affiliated investors, in the aggregate or in individual issuers. From time to time, each Fund’s activities also may be restricted because of regulatory restrictions applicable to the Investment Manager and its affiliates and/or because of their internal policies.

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 as, among others, motor vehicle installment sales, contracts, installment loan contracts, leases of various types of real and personal property, and receivables from revolving (credit card) agreements. Such securities entitle the security holders to receive distributions (i.e., principal and interest) that are tied to the payments made by the borrower 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 Types of Investments – Variable- and Floating-Rate Obligations, Types of Investments – Zero-Coupon, Pay-in-Kind and Step-Coupon Securities and Types of Investments – Private Placement and Other Restricted Securities for more information.

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with asset-backed securities include: Credit Risk, Interest Rate Risk, Liquidity Risk and Prepayment and Extension Risk.

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 Types of 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. 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 banks with interest and principal paid in U.S. dollars. Eurodollar and Yankee Dollar 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. See Types of Investments – Eurodollar and Yankee Dollar Instruments . 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. 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, a 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. A Fund also may hold funds on deposit with its custodian for temporary purposes.

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 and/or heightened 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 and/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 (including, less stringent) from those applicable to domestic banks. Foreign banks generally are not subject to examination by any U.S. Government agency or instrumentality. See Types of Investments – Foreign Securities .

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with bank obligations include: Credit Risk, Interest Rate Risk, Issuer Risk, and Prepayment and Extension Risk.

Collateralized Bond Obligations

Collateralized bond obligations (CBOs) are investment grade bonds backed by a pool of bonds, which may include junk bonds (which are considered speculative investments). CBOs are similar in concept to collateralized mortgage obligations (CMOs), but differ in that CBOs represent different degrees of credit quality rather than different maturities. (See Types of Investments-Mortgage-Backed Securities and - Asset-Backed Securities .) CBOs are often privately offered and sold, and thus not registered under securities laws. Underwriters of CBOs package a large and diversified pool of high-risk, high-yield junk bonds, which is then structured into “tranches.” Typically, the first tranche represents the higher quality collateral and pays the lowest interest rate; the second tranche is backed by riskier bonds and pays a higher rate; the third tranche represents the lowest credit quality and instead of receiving a fixed interest rate receives the residual interest payments – money that is left over after the higher tranches have been paid. CBOs, like CMOs, are substantially overcollateralized and this, plus the diversification of the pool backing them, may earn certain of the tranches investment-grade bond ratings. Holders of third-tranche CBOs stand to earn higher or lower yields depending on the rate of defaults in the collateral pool. See Types of Investments-Low and Below Investment Grade (High Yield) Securities .

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with CBOs include: Credit Risk, Illiquid Securities Risk, Interest Rate Risk, Liquidity Risk, Low and Below Investment Grade (High-Yield) Securities Risk and Prepayment and Extension Risk.

Commercial Paper

Commercial paper is a short-term debt obligation, usually sold on a discount basis, with a maturity ranging from 2 to 270 days issued by banks, corporations and other borrowers. It is sold to investors with temporary idle cash as a way to increase returns on a short-term basis. These instruments are generally unsecured, which increases the credit risk associated with this type of investment. See Types of Investments-Debt Obligations and - Illiquid Securities . See Appendix A for a discussion of securities ratings.

Although one or more of the other risks described in this SAI may apply, the risks typically associated with commercial paper include: Credit Risk and Liquidity Risk.

Common Stock

Common stock represents a unit of equity ownership of a corporation. Owners typically are entitled to vote on the selection of directors and other important corporate governance matters, and to receive dividend payments, if any, on their holdings. However, ownership of common stock does not entitle owners to participate in the day-to-day operations of the corporation. Common stocks of domestic and foreign public corporations can be listed, and their shares traded, on domestic stock exchanges, such as the NYSE or the NASDAQ Stock Market. Domestic and foreign corporations also may have their shares traded on foreign exchanges, such as the London Stock Exchange or Tokyo Stock Exchange. See Types of Investments – Foreign Securities . Common stock may be privately placed or publicly offered. The price of common stock is generally determined by corporate earnings, type of products or services offered, projected growth rates, experience of management, liquidity, and market conditions generally. In the event that a corporation declares bankruptcy or is liquidated, the claims of secured and unsecured creditors and owners of bonds and preferred stock take precedence over the claims of those who own common stock. See Types of Investments – Private Placement and Other Restricted Securities – Preferred Stock and - Convertible Securities for more information.

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with common stock include: Issuer Risk and Market Risk.

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 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.

Table of Contents

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 Types of Investments – Variable- and Floating-Rate Obligations, Types of Investments – Zero-Coupon, Pay-in-Kind and Step-Coupon Securities, Types of Investments – Common Stock, Types of Investments – Corporate Debt Securities and Types of Investments – Private Placement and Other Restricted Securities for more information.

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 at 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.

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with convertible securities include: Convertible Securities Risk, Interest Rate Risk, Issuer Risk, Market Risk, Prepayment and Extension Risk, and Reinvestment Risk.

Corporate Debt Securities

Corporate debt securities are long and short term fixed income securities typically issued by businesses to finance their operations. Corporate debt securities are issued by private companies, as distinct from debt securities issued by a government or its agencies. The issuer of a corporate debt security often has a contractual obligation to pay interest at a stated rate on specific dates and to repay principal periodically or on a specified maturity date. Corporate debt securities typically have four distinguishing features: (1) they are taxable; (2) they have a par value of $1,000; (3) they have a term maturity, which means they come due at a specified time period; and (4) many are traded on major securities exchanges. 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, as are debentures. See Appendix A for a discussion of securities ratings. 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. The category also includes bank loans, as well as assignments, participations and other interests in bank loans. 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. They may also be senior or subordinated obligations. See Types of Investments – Variable- and Floating-Rate Obligations, Types of Investments – Zero-Coupon, Pay-in-Kind and Step-Coupon Securities Types of Investments – Private Placement and Other Restricted Securities – Debt Obligations, Types of Investments – Commercial Paper and – Low and Below Investment Grade 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.

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with corporate debt securities include: Credit Risk, Interest Rate Risk, Issuer Risk, High Yield Securities Risk, Prepayment and Extension Risk and Reinvestment Risk.

Custody Receipts and Trust Certificates

Custody receipts and trust certificates are derivative products that evidence direct ownership in a pool of securities. Typically, a sponsor will deposit a pool of securities with a custodian in exchange for custody receipts evidencing interests in those securities. The sponsor generally then will sell the custody receipts or trust certificates in negotiated transactions at varying prices. Each custody receipt or trust certificate evidences the individual securities in the pool and the holder of a custody receipt or trust certificate generally will have all the rights and privileges of owners of those securities.

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with custody receipts and trust certificates include: Liquidity Risk and Counterparty Risk. In addition, custody receipts and trust certificates generally are subject to the same risks as the securities evidenced by the receipts or certificates.

Debt Obligations

Many different types of debt obligations exist (for example, bills, bonds, and notes). Issuers of debt obligations have a contractual obligation to pay interest at a fixed, variable or floating rate on specified dates and to repay principal by a specified maturity date. Certain debt obligations (usually intermediate and long-term bonds) have provisions that allow the issuer to redeem or “call” a bond before its maturity. Issuers are most likely to call these securities during periods of falling interest rates. When this happens, an investor may have to replace these securities with lower yielding securities, which could result in a lower return.

The market value of debt obligations is affected primarily by changes in prevailing interest rates and the issuers perceived ability to repay the debt. The market value of a debt obligation generally reacts inversely to interest rate changes. When prevailing interest rates decline, the market value of the bond usually rises, and when prevailing interest rates rise, the market value of the bond usually declines.

In general, the longer the maturity of a debt obligation, the higher its yield and the greater the sensitivity to changes in interest rates. Conversely, the shorter the maturity, the lower the yield and the lower the sensitivity to changes in interest rates.

As noted, the values of debt obligations also may be affected by changes in the credit rating or financial condition of their issuers. Generally, the lower the quality rating of a security, the higher the degree of risk as to the payment of interest and return of principal. To compensate investors for taking on such increased risk, those issuers deemed to be less creditworthy generally must offer their investors higher interest rates than do issuers with better credit ratings. See Types of Investments-Corporate Debt Securities and Low and Below Investment Grade (High Yield) Securities .

Determining Investment Grade for Purposes of Investment Policies . When determining whether a security is investment grade or below investment grade for purposes of investment policies of investing in such securities, the Funds use the middle rating of Moody’s, S&P and Fitch after excluding the highest and lowest available ratings. When a rating from only two of these agencies is available, the lower rating is used. When a rating from only one of these agencies is available, that rating is used. When a security is not rated by one of these agencies, the Investment Manager or, as applicable, a subadviser, determines whether it is of investment grade or below investment grade (e.g., junk bond) quality. See Appendix A for a discussion of securities ratings.

All ratings limitations are applied at the time of purchase. Subsequent to purchase, a debt security may cease to be rated or its rating may be reduced below the minimum required for purchase by a Fund. Neither event will require the sale of such a security, but it will be a factor in considering whether to continue to hold the security.

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with debt obligations include: Credit Risk, Interest Rate Risk, Issuer Risk, Liquidity Risk, Prepayment and Extension Risk and Reinvestment Risk.

Depositary Receipts

Some foreign securities are traded in the form of American Depositary Receipts (ADRs). ADRs are receipts typically issued by a U.S. bank or trust company evidencing ownership of the underlying securities of foreign issuers. European Depositary Receipts (EDRs) and Global Depositary Receipts (GDRs) are receipts typically issued by foreign banks or trust companies, evidencing ownership of underlying securities issued by either a foreign or U.S. issuer. Generally, depositary receipts in registered form are designed for use in the U.S. and depositary receipts in bearer form are designed for use in securities markets outside the U.S. Depositary receipts may not necessarily be denominated in the same currency as the underlying securities into which they may be converted. Depositary receipts involve the risks associated with the investments in underlying foreign securities. In addition, ADR holders may not have all the legal rights of shareholders and may experience difficulty in receiving shareholder communications. (See also Common Stock and Foreign Securities.)

Although one or more of the other risks described in this SAI may apply, the largest risks associated with depositary receipts include: Foreign/Emerging Markets Securities Risk, Issuer Risk, and Market Risk.

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), market indices (such as the S&P 500 ^® Index) or customized baskets of securities or instruments. 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. Many derivative instruments often require little or no initial payment and therefore often create inherent economic leverage. Derivatives, when used properly, can enhance returns and be useful in hedging portfolios and managing risk. 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.

A Fund may use derivatives for a variety of reasons, including, for example: (i) to enhance its return; (ii) to attempt to protect against possible unfavorable 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; (vi) to manage the effective maturity or duration of its portfolio; and/or (vii) to maintain cash reserves while remaining fully invested.

A 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.

CFTC Regulation . Each of the Funds listed on the cover of this SAI is deemed not to be a commodity pool under the Commodity Exchange Act (“CEA”) and has filed a notice of exclusion under U.S. Commodities Futures Trading Commission (“CFTC”) Rule 4.5.

Tax and Accounting Treatment . As permitted under federal income tax laws and to the extent a fund is allowed to invest in futures contracts, a fund would intend to identify futures contracts as part of a mixed straddle and not mark them to market, that is, not treat them as having been sold at the end of the year at market value. If a fund is using short futures contracts for hedging purposes, the fund may be required to defer recognizing losses incurred on short futures contracts and on underlying securities. Any losses incurred on securities that are part of a straddle may be deferred to the extent there is unrealized appreciation on the offsetting position until the offsetting position is sold. Federal income tax treatment of gains or losses from transactions in options, options on futures contracts and indexes will depend on whether the option is a section 1256 contract. If the option is a non-equity option, a fund would either make a 1256(d) election and treat the option as a mixed straddle or mark to market the option at fiscal year-end and treat the gain/loss as 40% short-term and 60% long-term. The Internal Revenue Service (IRS) has ruled publicly that an exchange-traded call option is a security for purposes of the 50%-of-assets test and that its issuer is the issuer of the underlying security, not the writer of the option, for purposes of the diversification requirements.

Accounting for futures contracts will be according to generally accepted accounting principles. Initial margin deposits will be recognized as assets due from a broker (a fund’s agent in acquiring the futures position). During the period the futures contract is open, changes in value of the contract will be recognized as unrealized gains or losses by marking to market on a daily basis to reflect the market value of the contract at the end of each day’s trading. Variation margin payments will be made or received depending upon whether gains or losses are incurred. All contracts and options will be valued at the last-quoted sales price on their primary exchange.

Other Risks of Derivatives . The primary risk of derivatives is the same as the risk of the underlying asset, namely that the value of the underlying asset may go up or down. Adverse movements in the value of an underlying asset can expose an investor to losses. Derivative instruments may include elements of leverage and, accordingly, the fluctuation of the value of the derivative instrument in relation to the underlying asset may be magnified. The successful use of derivative instruments depends upon a variety of factors, particularly the investment manager’s ability to predict movements of the securities, currencies, and commodity markets, which requires different skills than predicting changes in the prices of individual securities. There can be no assurance that any particular strategy will succeed.

Another risk is the risk that a loss may be sustained as a result of the failure of a counterparty to comply with the terms of a derivative instrument. The counterparty risk for exchange-traded derivative instruments is generally less than for privately-negotiated or OTC derivative instruments, since generally a clearing agency, which is the issuer or counterparty to each exchange-traded instrument, provides a guarantee of performance. For privately-negotiated instruments, there is no similar clearing agency guarantee. In all transactions, an investor will bear the risk that the counterparty will default, and this could result in a loss of the expected benefit of the derivative transaction and possibly other losses.

When a derivative transaction is used to completely hedge another position, changes in the market value of the combined position (the derivative instrument plus the position being hedged) result from an imperfect correlation between the price movements of the two instruments. With a perfect hedge, the value of the combined position remains unchanged for any change in the price of the underlying asset. With an imperfect hedge, the values of the derivative instrument and its hedge are not perfectly correlated. For example, if the value of a derivative instrument used in a short hedge (such as writing a call option, buying a put option, or selling a futures contract) increased by less than the decline in value of the hedged investment, the hedge would not be perfectly correlated. Such a lack of correlation might occur due to factors unrelated to the value of the investments being hedged, such as speculative or other pressures on the markets in which these instruments are traded.

Derivatives also are subject to the risk that they cannot be sold, closed out, or replaced quickly at or very close to their fundamental value. Generally, exchange contracts are very liquid because the exchange clearinghouse is the counterparty of every contract. OTC transactions are less liquid than exchange-traded derivatives since they often can only be closed out with the other party to the transaction.

Another risk is caused by the legal unenforceability of a party’s obligations under the derivative. A counterparty that has lost money in a derivative transaction may try to avoid payment by exploiting various legal uncertainties about certain derivative products.

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with transactions in derivatives (including the derivatives instruments discussed below) include: Counterparty Risk, Credit Risk, Interest Rate Risk, Leverage Risk, Liquidity Risk, Market Risk, Derivatives Risk, Derivatives Risk/Credit Default Swaps Risk, Derivatives Risk/Forward Foreign Currency Contracts Risk, Derivatives Risk/Commodity-Linked Futures Contracts Risk, Derivatives Risk/Commodity-Linked Structured Notes Risk, Derivatives Risk/Commodity-Linked Swaps, Derivatives Risk/Forward Interest Rate Agreements Risk, Derivatives Risk/Futures Contracts Risk, Derivatives Risk/Interest Rate Swaps Risk, Derivatives Risk/Inverse Floaters Risk, Derivatives Risk/Options Risk, Derivatives Risk/Portfolio Swaps and Total Return Swaps Risk, Derivatives Risk/Total Return Swaps Risk, and Derivatives Risk/Warrants Risk.

Index or Linked Securities (Structured Products)

General. Indexed or linked securities, also often referred to as “structured products,” are instruments that may have varying combinations of equity and debt characteristics. These instruments are structured to recast the investment characteristics of the underlying security or reference asset. If the issuer is a unit investment trust or other special purpose vehicle, the structuring will typically involve the deposit with or purchase by such issuer of specified instruments (such as commercial bank loans or securities) and/or the execution of various derivative transactions, and the issuance by that entity of one or more classes of securities (structured securities) backed by, or representing interests in, the underlying instruments. The cash flow on the underlying instruments may be apportioned among the newly issued structured securities to create securities with different investment characteristics, such as varying maturities, payment priorities and interest rate provisions, and the extent of such payments made with respect to structured securities is dependent on the extent of the cash flow on the underlying instruments.

Indexed and Inverse Floating Rate Securities . A Fund may invest in securities that provide a potential return based on a particular index or interest rates. For example, a Fund may invest in debt securities that pay interest based on an index of interest rates. The principal amount payable upon maturity of certain securities also may be based on the value of the index. To the extent a Fund invests in these types of securities, a Fund’s return on such securities will rise and fall with the value of the particular index: that is, if the value of the index falls, the value of the indexed securities owned by a Fund will fall. Interest and principal payable on certain securities may also be based on relative changes among particular indices.

A Fund may also invest in so-called “inverse floaters” or “residual interest bonds” on which the interest rates vary inversely with a floating rate (which may be reset periodically by a dutch auction, a remarketing agent, or by reference to a short-term tax-exempt interest rate index). A Fund may purchase synthetically-created inverse floating rate bonds evidenced by custodial or trust receipts. A trust funds the purchase of a bond by issuing two classes of certificates: short-term floating rate notes (typically sold to third parties) and the inverse floaters (also known as residual certificates). No additional income beyond that provided by the trust’s underlying bond is created; rather, that income is merely divided-up between the two classes of certificates. Generally, income on inverse floating rate bonds will decrease when interest rates increase, and will

- 15 -

Table of Contents

increase when interest rates decrease. Such securities can have the effect of providing a degree of investment leverage, since they may increase or decrease in value in response to changes in market interest rates at a rate that is a multiple of the actual rate at which fixed-rate securities increase or decrease in response to such changes. As a result, the market values of such securities will generally be more volatile than the market values of fixed-rate securities. To seek to limit the volatility of these securities, a Fund may purchase inverse floating obligations that have shorter-term maturities or that contain limitations on the extent to which the interest rate may vary. Certain investments in such obligations may be illiquid. Furthermore, where such a security includes a contingent liability, in the event of an adverse movement in the underlying index or interest rate, a Fund may be required to pay substantial additional margin to maintain the position.

Credit Linked Securities . Among the income-producing securities in which a Fund may invest are credit linked securities. The issuers of these securities frequently are limited purpose trusts or other special purpose vehicles that, in turn, invest in a derivative instrument or basket of derivative instruments, such as credit default swaps, interest rate swaps and other securities, in order to provide exposure to certain fixed income markets. For instance, a Fund may invest in credit linked securities as a cash management tool in order to gain exposure to a certain market and/or to remain fully invested when more traditional income-producing securities are not available. Like an investment in a bond, investments in these credit linked securities represent the right to receive periodic income payments (in the form of distributions) and payment of principal at the end of the term of the security. However, these payments are conditioned on or linked to the issuer’s receipt of payments from, and the issuer’s potential obligations to, the counterparties to the derivative instruments and other securities in which the issuer invests. For instance, the issuer may sell one or more credit default swaps, under which the issuer would receive a stream of payments over the term of the swap agreements provided that no event of default has occurred with respect to the referenced debt obligation upon which the swap is based. If a default occurs, the stream of payments may stop and the issuer would be obligated to pay the counterparty the par (or other agreed upon value) of the referenced debt obligation. This, in turn, would reduce the amount of income and/or principal that a Fund would receive. A Fund’s investments in these instruments are indirectly subject to the risks associated with derivative instruments. These securities generally are exempt from registration under the 1933 Act. Accordingly, there may be no established trading market for the securities and they may constitute illiquid investments.

Index- and Currency Securities . “Index-linked” notes are debt securities of companies that call for interest payments and/or payment at maturity in different terms than the typical note where the borrower agrees to make fixed interest payments and to pay a fixed sum at maturity. Principal and/or interest payments on an index-linked note depend on the performance of one or more market indices, such as the S&P 500 ^® Index, a weighted index of commodity futures such as crude oil, gasoline and natural gas or the market prices of a particular commodity or basket of commodities or securities. Currency-linked debt securities are short-term or intermediate-term instruments having a value at maturity, and/or an interest rate, determined by reference to one or more foreign currencies. Payment of principal or periodic interest may be calculated as a multiple of the movement of one currency against another currency, or against an index.

Index and currency securities may entail substantial risks. Such instruments may be subject to significant price volatility. The company issuing the instrument may fail to pay the amount due on maturity. The underlying investment may not perform as expected by a Fund’s portfolio manager. Markets and underlying investments and indexes may move in a direction that was not anticipated by a Fund’s portfolio manager. Performance of the derivatives may be influenced by interest rate and other market changes in the United States and abroad, and certain derivative instruments may be illiquid.

Linked securities are often issued by unit investment trusts. Examples of this include such index-linked securities as S&P Depositary Receipts (SPDRs), which is an interest in a unit investment trust holding a portfolio of securities linked to the S&P 500 ^® Index, and a type of exchange-traded fund (ETF). Because a unit investment trust is an investment company under the 1940 Act, a Fund’s investments in SPDRs are subject to the limitations set forth in Section 12(d)(1)(A) of the 1940 Act. SPDRs generally closely track the underlying portfolio of securities, trade like a share of common stock and pay periodic dividends proportionate to those paid by the portfolio of stocks that comprise the S&P 500 ^® Index. As a holder of interests in a unit investment trust, a Fund would indirectly bear its ratable share of that unit investment trust’s expenses. At the same time, a Fund would continue to pay its own management and advisory fees and other expenses, as a result of which a Fund and its shareholders in effect would be absorbing levels of fees with respect to investments in such unit investment trusts.

Because linked securities typically involve no credit enhancement, their credit risk generally will be equivalent to that of the underlying instruments. Investments in structured products may be structured as a class that is either subordinated or unsubordinated to the right of payment of another class. Subordinated linked securities typically have higher rates of return and present greater risks than unsubordinated structured products. Structured products sometimes are sold in private placement transactions and often have a limited trading market.

Investments in linked securities have the potential to lead to significant losses because of unexpected movements in the underlying financial asset, index, currency or other investment. The ability of a Fund to utilize linked securities successfully will depend on its ability correctly to predict pertinent market movements, which cannot be assured. Because currency-linked securities usually relate to foreign currencies, some of which may be currencies from emerging market countries, there are certain additional risks associated with such investments.

Commodity-Linked Structured Notes . Commodity-linked structured notes have characteristics of both a debt security and a commodity-linked derivative. A commodity-linked note typically provides for interest payments and a principal payment at maturity linked to the price movement of the underlying commodity, commodity index or commodity futures or option contract. Typically, commodity-linked structured notes are issued by a bank or other financial institution or a commodity producer at a specified face value (for example $100 or $1,000). They usually pay interest at a fixed or floating rate until they mature, which is normally in 12 to 18 months. At maturity, the fund receives a payment that is calculated based on the price increase or decrease of an underlying commodity-related variable and may be based on a multiple of the price movement of that variable. The underlying commodity-related variable may be: a physical commodity (such as heating oil, livestock, or agricultural products), a commodity futures or option contract, a commodity index (such as the S&P GSCI), or some other readily measurable variable that reflects changes in the value of particular commodities or the commodities markets.

A fund may negotiate with the issuer to modify specific terms and features to tailor the note to the fund’s investment needs. For example, the fund can negotiate to extend or shorten the maturity of a commodity-linked note, or to receive interest payments at a variable interest rate instead of at a fixed interest rate. In that regard, commodity-linked structure notes may be principally protected, partially protected, or offer no principal protection. A principal protected commodity-linked note means that the issuer will pay, at a minimum, the par value of the note at maturity. Therefore, if the commodity value to which the commodity-linked structured note is linked declines over the life of the note, a fund will receive at maturity the face or stated value of the note.

With a principal protected commodity-linked note, a fund will receive at maturity the greater of the par value of the note or the value of the underlying commodity or index. This protection is, in effect, an option whose value is subject to the volatility and price level of the underlying commodity. This optionality can be added to the note’s structure, but only for a cost higher than that of a partially protected (or no protection) commodity-linked note. The portfolio manager(s)’s decision on whether to use principal protection depends in part on the cost of the protection. In addition, the protection feature depends upon the ability of the issuer to meet its obligation to buy back the security, and therefore depends on the creditworthiness of the issuer.

With full principal protection, a fund will receive at maturity of the commodity-linked note either the stated par value of the commodity-linked note, or potentially, an amount greater than the stated par value if the underlying commodity, index, futures or option contract or other underlying economic variable increases in value. Partially protected commodity-linked notes may suffer some loss of principal if the underlying commodity, index, futures or options contract or other economic variable declines in value during the term of the note. However, partially protected commodity-linked notes have a specified limit as to the amount of principal that they may lose.

A fund may also invest in commodity-linked notes that offer no principal protection. At maturity, there is a risk that the underlying commodity price, futures or options contract, index or other economic variable may have declined sufficiently in value such that some or all of the face value of the commodity-linked note might not be returned. Some of the commodity-linked structured notes that a fund may invest in may have no principal protection and thus, the note could lose all of its value. In deciding to purchase a note without principal protection, the portfolio manager(s) may consider, among other things, the expected performance of the underlying commodity futures or option contract, index or other economic variable over the term of the note, the cost of the note, and any other economic factors which the portfolio manager(s) believes are relevant.

A significant risk of commodity-linked structured notes is counterparty risk. A fund will take on the counterparty credit risk of the issuer. That is, at maturity of a commodity-linked note, there is a risk that the issuer may be unable to perform its obligations under the terms of the commodity-linked note.

Certain structured notes and swap agreements may be exempt from provisions of the CEA and therefore, are not regulated as commodity interests under the CEA, pursuant to regulations approved by the CFTC. These are referred to as “qualifying hybrid instruments” and must meet certain specific legal requirements. To qualify for this exemption, a structured note or swap agreements must be entered into by “eligible participants,” which include the following, provided the participants’ total assets exceed established levels: a bank or trust company, savings association or credit union, insurance company, investment company subject to regulation under the 1940 Act, commodity pool, corporation, partnership, proprietorship, organization, trust or other entity, employee benefit plan, governmental entity, broker-dealer, futures commission merchant, natural person, or regulated foreign person. To be eligible, natural persons and most other entities must have total assets exceeding $10 million; commodity pools and employee benefit plans must have assets exceeding $5 million. In addition, an eligible structured note or swap transaction must meet three conditions. First, the structured note or swap agreement may

- 17 -

Table of Contents

not be part of a fungible class of agreements that are standardized as to their material economic terms. Second, the creditworthiness of parties with actual or potential obligations under the structured note or swap agreement must be a material consideration in entering into or determining the terms of the instrument, including pricing, cost or credit enhancement terms. Third, structured notes or swap agreements may not be entered into and traded on or through a multilateral transaction execution facility. This exemption is not exclusive, and participants may continue to rely on existing exclusions for swaps, such as the Policy Statement issued in July 1989 which recognized a safe harbor for swap transactions from regulation as futures or commodity option transactions under the CEA or its regulations. The Policy Statement applies to swap transactions settled in cash that (1) have individually tailored terms, (2) lack exchange-style offset and the use of a clearing organization or margin system, (3) are undertaken in conjunction with a line of business, and (4) are not marketed to the public.

A fund may invest in commodity-linked notes that are excluded from regulation under the CEA and the rules thereunder to the extent necessary for the fund not to be considered a “commodity pool.” Although a fund may invest up to 100% of its total assets in commodity-linked structured notes that are considered to be “qualifying hybrid instruments,” from time to time it may invest a portion of its assets in commodity-linked notes and other commodity-linked derivatives that do not qualify for exemption from regulation under the CEA.

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. A 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.

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 Funds, neither the Trust nor any of the individual Funds 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. However, the CFTC is implementing significant changes in the way in which registered investment companies that invest in commodities markets are regulated. As a result of these changes, certain Funds may be compelled to consider significant changes, which could include altering its investment strategies (e.g., reducing substantially the Fund’s exposure to the commodities markets) or becoming subject to registration or regulation as a “commodity pool operator” under the CEA.

Upon entering into futures contracts, in compliance with regulatory requirements, cash or liquid securities, equal in value to the amount of a Fund’s obligation under the contract (less any applicable margin deposits and any assets that constitute “cover” for such obligation), will be segregated with a Fund’s custodian.

Unlike when a Fund purchases or sells a security, no price is paid or received by a Fund upon the purchase or sale of a futures contract, although a 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 a 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 a 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. A 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. A 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 a 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 a Fund, and a 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 a Fund is subject to a Fund’s portfolio manager 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. A 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.

In the event of adverse price movements, a Fund would continue to be required to make daily cash payments in order to maintain its required margin. In such a situation, if a 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 a Fund, a 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 a 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, a Fund may use interest rate futures contracts as a defense, or hedge, against anticipated interest rate changes. A 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 a Fund, through using futures contracts.

Table of Contents

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. A 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. A 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. A Fund may enter into stock index futures contracts, debt index futures contracts, or other index futures contracts appropriate to its objective(s).

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.

Commodity-Linked Futures Contracts . Commodity-linked futures contracts are traded on futures exchanges.

Futures contracts are standardized, exchange-traded contracts that provide for the sale or purchase of a specified financial instrument, asset or currency at a future time at a specified price. Futures are generally bought and sold on the commodities exchanges where they are listed with payment of initial and variation margin, as described below. A futures contract generally obligates the purchaser to take delivery from the seller the specific type of financial instrument or commodity underlying the contract at a specific future time for a set price. The purchase of a futures contract enables a fund, during the term of the contract, to lock in the price at which it may purchase a security, currency or commodity and protect against a rise in prices pending the purchase of portfolio investments. A futures contract generally obligates the seller to deliver to the buyer the specific type of financial instrument underlying the contract at a specific future time for a set price. The sale of a futures contract enables a fund to lock in a price at which it may sell a security, currency or commodity and protect against declines in the value of portfolio investments. The value of a futures contract tends to increase and decrease in tandem with the value of the underlying instrument.

A fund can hold a portion of its investments in commodity-linked futures contracts. Commodity-linked futures contracts are traded on futures exchanges. These futures exchanges offer a central marketplace in which to transact futures contracts, a clearing corporation to process trades, a standardization of expiration dates and contract sizes, and the availability of a secondary market. Futures markets also specify the terms and conditions of delivery as well as the maximum permissible price movement during a trading session. Additionally, the commodity futures exchanges may have position limit rules that limit the amount of futures contracts that any one party may hold in a particular commodity at any point in time. These position limit rules are designed to prevent any one participant from controlling a significant portion of the market.

Commodity-linked futures contracts are generally based upon commodities within five main commodity groups: (1) energy, which includes, among others, crude oil, brent crude oil, gas oil, natural gas, gasoline and heating oil; (2) livestock, which includes, among others, feeder cattle, live cattle and hogs; (3) agriculture, which includes, among others, wheat (Kansas wheat and Chicago wheat), corn, soybeans, cotton, coffee, sugar and cocoa; (4) industrial metals, which includes, among others, aluminum, copper, lead, nickel and zinc; and (5) precious metals, which includes, among others, gold and silver. A fund may purchase commodity futures contracts, options on futures contracts and options and futures on commodity indices with respect to these five main commodity groups and the individual commodities within each group, as well as other types of commodities.

The purchase or sale of a futures contract by a fund differs from the purchase or sale of a security or option in that no price or premium is paid or received. Rather, upon entering into a futures transaction for contracts that cash settle, the fund will be required, as security for its obligations under the contract, to deposit with the futures commission merchant (the “futures broker”) an initial margin payment, consisting of cash, U.S. Government securities or other liquid assets typically ranging from approximately less than 1% to 15% of the contract amount. The initial margin is set by the exchange on which the

- 20 -

Table of Contents

futures contract is traded and may, from time to time, be modified. In addition, the futures broker may establish margin deposit requirements in excess of those required by the exchange. Initial margin payments will be deposited with the fund’s custodian bank in an account registered in the futures broker’s name. However, the futures broker can gain access to that account only under specified conditions. The margin deposits made are marked to market daily and a fund may be required to make subsequent deposits of cash, U.S. Government securities or other liquid assets, called “variation margin” or “maintenance margin,” which reflects the price fluctuations of the futures contract. By setting aside assets equal to only its net obligations under cash-settled futures contracts, a fund will have the ability to employ leverage to a greater extent than if a fund were required to segregate assets equal to the full notional amount of the futures contract. Notwithstanding the foregoing, with respect to futures contracts that do not cash settle, a fund may be required to set aside liquid assets equal to the full notional value of the futures contract while the position is open.

Depending on the terms of the particular contract, futures contracts are settled through either physical delivery of the underlying instrument on the settlement date or by payment of a cash settlement amount on the settlement date. In particular, commodity futures contracts normally specify a certain date for the delivery of the underlying physical commodity. In order to avoid the delivery process and maintain a long futures position, futures contracts are typically replaced as they approach expiration by contracts that have a later expiration. This process is known as “rolling” a futures position. As a result, the fund does not expect to engage in physical settlement of commodities futures.

The loss that may be incurred by a fund in entering into futures contracts is potentially unlimited and may exceed the amount of the premium. Futures markets are highly volatile and the use of futures may increase the volatility of the fund’s net asset value (NAV). Additionally, as a result of the low margin deposits normally required in futures trading, a relatively small price movement in a futures contract may result in substantial losses to the fund.

The price of a commodity futures contract will reflect the storage costs of purchasing the physical commodity. These storage costs include the time value of money invested in the physical commodity plus the actual costs of storing the commodity less any benefits from ownership of the physical commodity that are not obtained by the holder of a futures contract (this is sometimes referred to as the “convenience yield”). To the extent that these storage costs change for an underlying commodity while a fund is long futures contracts on that commodity, the value of the futures contract may change proportionately.

In the commodity futures markets, if producers of the underlying commodity wish to hedge the price risk of selling the commodity, they will sell futures contracts today to lock in the price of the commodity at delivery tomorrow. In order to induce speculators to take the corresponding long side of the same futures contract, the commodity producer must be willing to sell the futures contract at a price that is below the expected future spot price. Conversely, if the predominate hedgers in the futures market are the purchasers of the underlying commodity who purchase futures contracts to hedge against a rise in prices, then speculators will only take the short side of the futures contract if the futures price is greater than the expected future spot price of the commodity.

The changing nature of the hedgers and speculators in the commodity markets will influence whether futures prices are above or below the expected future spot price. This can have significant implications for a fund when it is time to replace an existing contract with a new contract. If the nature of hedgers and speculators in futures markets has shifted such that commodity purchasers are the predominate hedgers in the market, a fund might open the new futures position at a higher price or choose other related commodity-linked investments.

The values of commodities which underlie commodity futures contracts are subject to additional variables which may be less significant to the values of traditional securities such as stocks and bonds. Variables such as drought, floods, weather, livestock disease, embargoes and tariffs may have a larger impact on commodity prices and commodity-linked investments, including futures contracts, commodity-linked structured notes, commodity-linked options and commodity-linked swaps, than on traditional securities. These additional variables may create additional investment risks which subject a fund’s commodity-linked investments to greater volatility than investments in traditional securities.

Futures contracts may be illiquid. The liquidity of the futures market depends on participants entering into offsetting transactions rather than making or taking delivery. To the extent participants decide to make or take delivery, liquidity in the futures market could be reduced. In the event a liquid market does not exist, it may not be possible to close out a futures position and, in the event of adverse price movements, a fund would continue to be required to make daily payments of variation margin. The absence of a liquid market in futures contracts might cause a fund to make or take delivery of the instruments or commodities underlying futures contracts at a time when it may be disadvantageous to do so. The inability to close out positions and futures positions could also have an adverse impact on a fund’s ability to effectively hedge its positions. Furthermore, as noted above, exchanges may limit fluctuations in futures contract prices during a trading session by imposing a maximum permissible price movement on each futures contract. A fund may be disadvantaged if it is prohibited from executing a trade outside the daily permissible price movement.

Futures contracts and options thereon which are purchased or sold on on-US commodities exchanges may have greater price volatility than their US counterparts. In addition, brokerage commissions, clearing costs and other transaction costs may be higher on non-U.S. exchanges. Furthermore, non-U.S. commodities exchanges may be less regulated and under less governmental scrutiny than U.S. exchanges. Neither the CFTC, National Futures Association, SEC or any domestic exchange regulates activities of any foreign exchange or boards of trade or any applicable foreign law. This is true even if the exchange is formally linked to a domestic market so that a position taken on the market may be liquidated by a transaction on another market. Moreover, such laws or regulations will vary depending on the foreign country in which the foreign futures or option transaction occurs. For these reasons, a fund’s investment in foreign futures or foreign options transactions may not be provided the same protections in respect of transactions on U.S. exchanges. In particular, persons who trade foreign futures or foreign options contracts may not be afforded certain of the protective measures provided by the CEA, the CFTC’s regulations and the rules of the National Futures Association and any domestic exchange, including the right to use reparations proceedings before the CFTC and arbitration proceedings provided by the National Futures Association or any domestic futures exchange. Similarly, those persons may not have the protection of the U.S. securities laws.

In the event of the bankruptcy of a broker through which a fund engages in transactions in futures or options thereon, a fund could experience delays and/or losses in liquidating open positions purchased or sold through the broker and/or incur a loss on all or part of its margin deposits made in furtherance of transactions through the broker.

Options on Futures Contracts. A Fund may purchase and write call and put options on those futures contracts that it is permitted to buy or sell. A 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, but not the obligation, 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.

A Fund will enter into written options on futures contracts only when, in compliance with regulatory 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. A 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.

Options on Index Futures Contracts . A 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.

Options on Stocks and Stock and Other Indices. A 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 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.

A Fund may, for the purpose of hedging its portfolio, subject to applicable securities regulations, purchase and write put and call options on foreign stock indices listed on foreign and domestic stock exchanges.

As an alternative to purchasing call and put options on index futures, a Fund may purchase call and put options on the underlying indices themselves. Such options could be used in a manner identical to the use of options on index futures. Options involving securities indices provide the holder with the right to make or receive a cash settlement upon exercise of the option based on movements in the relevant index. Such options must be listed on a national securities exchange and issued by the OCC. Such options may relate to particular securities or to various stock indices, except that a Fund may not write covered options on an index.

Writing Covered Options . A Fund may write covered call options and covered put options on securities held in its portfolio. Call options written by a Fund give the purchaser the right to buy the underlying securities from a 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 a Fund at the stated exercise price at any time prior to the expiration date of the option, regardless of the security’s market price.

A Fund may write only covered options, which means that, so long as a 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, a Fund will hold cash, cash equivalents, money market fund shares and/or high-grade short-term debt obligations equal to the price to be paid if the option is exercised. In addition, a 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. A Fund may write combinations of covered puts and calls (straddles) on the same underlying security.

A Fund will receive a premium from writing a put or call option, which increases a 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, a 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, a 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.

A 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 a 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. A 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 a Fund writes a call option but does not own the underlying security, and when it writes a put option, a 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, a 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 . A 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 a 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, a 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 . A Fund may purchase call options, including to hedge against an increase in the price of securities that a Fund wants ultimately to buy. Such hedge protection is provided during the life of the call option since a 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 a Fund might have realized had it bought the underlying security at the time it purchased the call option.

Over-the-Counter (OTC) Options . OTC options (options not traded on exchanges) are generally established through negotiation with the other party to the options contract. A Fund will enter into OTC options transactions only with primary dealers in U.S. Government securities and, in the case of OTC options written by a Fund, only pursuant to agreements that will assure that a Fund will at all times have the right to repurchase the option written by it from the dealer at a specified formula price. A Fund will treat the amount by which such formula price exceeds the amount, if any, by which the option may be “in-the-money” as an illiquid investment. It is the present policy of a Fund not to enter into any OTC option transaction if, as a result, more than 15% (10% in some cases, refer to your Fund’s prospectuses) of a Fund’s net assets would be invested in (i) illiquid investments (determined under the foregoing formula) relating to OTC options written by a Fund, (ii) OTC options purchased by a Fund, (iii) securities which are not readily marketable, and (iv) repurchase agreements maturing in more than seven days.

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 a 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. A Fund may enter into a variety of swap agreements, including interest rate, index, commodity, commodity futures, equity, equity index, credit default, bond futures, total return, portfolio, and currency exchange rate swap agreements, and other types of swap agreements such as caps, collars and floors. A Fund also may enter into swaptions, which are options to enter into a swap agreement.

Swap agreements are usually entered into without an upfront payment because the value of each party’s position is the same. The market values of the underlying commitments will change over time, resulting in one of the commitments being worth more than the other and the net market value creating a risk exposure for one counterparty or the other.

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 amounts 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. In interest rate collar transactions, one party sells a cap and purchases a floor, or vice versa, in an attempt to protect itself against interest rate movements exceeding given minimum or maximum levels or collar amounts.

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

Interest Rate Swaps . Interest rate swap agreements are often used to obtain or preserve a desired return or spread at a lower cost than through a direct investment in an instrument that yields the desired return or spread. They are financial instruments that involve the exchange of one type of interest rate cash flow for another type of interest rate cash flow on specified dates in the future. In a standard interest rate swap transaction, two parties agree to exchange their respective commitments to pay fixed or floating interest rates on a predetermined specified (notional) amount. The swap agreement’s notional amount is the predetermined basis for calculating the obligations that the swap counterparties have agreed to exchange. Under most swap agreements, the obligations of the parties are exchanged on a net basis. The two payment streams are netted out, with each party receiving or paying, as the case may be, only the net amount of the two payments. Interest rate swaps can be based on various measures of interest rates, including LIBOR, swap rates, Treasury rates and foreign interest rates.

Credit Default Swap Agreements . A 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 a 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. A Fund may be either the buyer or seller in a credit default swap. If a Fund is a buyer and no credit event occurs, a 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, a 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, a Fund would effectively add leverage to its portfolio because, in addition to its total net assets, a Fund would be subject to investment exposure on the notional amount of the swap.

Credit default swap agreements may involve greater risks than if a 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. A 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.

A Fund’s obligations under a credit default swap agreement will be accrued daily (offset against any amounts owing to the Fund). In connection with credit default swaps in which a Fund is the buyer, the Fund will segregate or “earmark” cash or other liquid assets, or enter into certain offsetting positions, with a value at least equal to the Fund’s exposure (any accrued but unpaid net amounts owed by the Fund to any counterparty), on a mark-to-market basis. In connection with credit default swaps in which a Fund is the seller, the Fund will segregate or “earmark” cash or other liquid assets, or enter into offsetting positions, with a value at least equal to the full notional amount of the swap (minus any amounts owed to the Fund). Such segregation or “earmarking” will ensure that a Fund has assets available to satisfy its obligations with respect to the transaction. Such segregation or “earmarking” will not limit a Fund’s exposure to loss.

Equity Swaps . A 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.

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 a Fund’s portfolio because, in addition to its total net assets, a 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 a Fund thereunder, and conversely, that a Fund will not be able to meet its obligation to the counterparty. Generally, a Fund will enter into total return swaps on a net basis (i.e., the two payment streams are netted against one another with a 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 a 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 a Fund. If the total return swap transaction is entered into on other than a net basis, the full amount of a Fund’s obligations will be accrued on a daily basis, and the full amount of a Fund’s obligations will be segregated by a 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 a Fund initially to make an equivalent direct investment, plus or minus any amount a 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.

Commodity-Linked Swaps. Swap agreements are two party contracts ranging from a few weeks to more than one year. In a standard swap transaction, two parties agree to exchange the returns (or differentials in rates of return) earned or realized on a predetermined financial instrument or instruments, which may be adjusted for an interest factor. The gross return to be exchanged or “swapped” between the parties is generally calculated with respect to a “notional amount” which is generally equal to the return on or increase in value of a particular dollar amount invested at a particular interest rate in such financial instrument or instruments.

Commodity-linked swaps are two party contracts in which the parties agree to exchange the return or interest rate on one instrument for the return of a particular commodity, commodity index or commodities futures or options contract. The payment streams are calculated by reference to an agreed upon notional amount. A one-period swap contract operates in a manner similar to a forward or futures contract because there is an agreement to swap a commodity for cash at only one forward date. A fund may engage in swap transactions that have more than one period and therefore more than one exchange of commodities.

A fund may invest in total return swaps to gain exposure to the overall commodity markets. In a total return commodity swap, a fund will receive the price appreciation of a commodity index, a portion of the index, or a single commodity in exchange for paying an agreed-upon fee. If the commodity swap is for one period, the fund will pay a fixed fee, established at the outset of the swap. However, if the term of the commodity swap is more than one period, with interim swap payments, the fund will pay an adjustable or floating fee. With “floating” rate, the fee is pegged to a base rate such as the London Interbank Offered Rate (“LIBOR”), and is adjusted each period. Therefore, if interest rates increase over the term of the swap contract, a fund may be required to pay a higher fee at each swap reset date.

Cross Currency Swaps . Cross currency swaps are similar to interest rate swaps, except that they involve multiple currencies. A Fund may enter into a cross currency swap when it has exposure to one currency and desires exposure to a different currency. Typically, the interest rates that determine the currency swap payments are fixed, although occasionally one or both parties may pay a floating rate of interest. Unlike an interest rate swap, however, the principal amounts are exchanged at the beginning of the contract and returned at the end of the contract. In addition to paying and receiving amounts at the beginning and termination of the agreements, both sides will have to pay in full periodically based upon the currency they have borrowed. Changes in foreign exchange currency rates and changes in interest rates, as described above, may negatively affect currency swaps.

Contracts for Differences. Contracts for differences are swap arrangements in which the parties agree that their return (or loss) will be based on the relative performance of two different groups or baskets of securities. Often, one or both baskets will be an established securities index. A Fund’s return will be based on changes in value of theoretical long futures positions in the securities comprising one basket (with an aggregate face value equal to the notional amount of the contract for differences) and theoretical short futures positions in the securities comprising the other basket. A Fund also may use actual long and short futures positions and achieve similar market exposure by netting the payment obligations of the two contracts. A Fund typically enters into contracts for differences (and analogous futures positions) when its portfolio manager believes that the basket of securities constituting the long position will outperform the basket constituting the short position. If the short basket outperforms the long basket, a Fund will realize a loss – even in circumstances when the securities in both the long and short baskets appreciate in value.

Swaptions . A swaption is an options contract on a swap agreement. These transactions that give a counterparty the right (but not the obligation) to enter into new swap agreements or to shorten, extend, cancel or otherwise modify an existing swap agreement (which are described herein) at some designated future time on specified terms, in return for payment of the purchase price (the “premium”) of the option. A Fund may write (sell) and purchase put and call swaptions to the same extent it may make use of standard options on securities or other instruments. The writer of the contract receives the premium and bears the risk of unfavorable changes in the market value on the underlying swap agreement. Swaptions can be bundled and sold as a package. These are commonly called interest rate caps, floors and collars (which are described herein).

Eurodollar and Yankee Dollar and Related Derivatives Instruments

Eurodollar instruments are bonds that pay interest and principal in U.S. dollars held in banks outside the United States, primarily in Europe. Eurodollar instruments are usually issued on behalf of multinational companies and foreign governments by large underwriting groups composed of banks and issuing houses from many countries. Yankee Dollar instruments are U.S. dollar-denominated bonds issued in the United States by foreign banks and corporations. These investments involve risks that are different from investments in securities issued by U.S. issuers.

Eurodollar futures contracts enable purchasers to obtain a fixed rate for the lending of funds and sellers to obtain a fixed rate for borrowings. A Fund may use Eurodollar futures contracts and options thereon to hedge against changes in the LIBOR, to which many interest rate swaps and fixed income instruments are linked.

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with Eurodollar and Yankee Dollar instruments include: Credit Risk, Foreign Securities Risk, Interest Rate Risk and Issuer Risk.

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 securities on a specified future date and price from the same party. Mortgage dollar rolls and U.S. Treasury rolls are types of dollar rolls. A Fund foregoes principal and interest paid on the securities during the “roll” period. A 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. The investor also could be compensated through the receipt of fee income equivalent to a lower forward price.

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with mortgage dollar rolls include: Counterparty Risk, Credit Risk and Interest Rate Risk.

Equity-Linked Notes

An equity-linked note (ELN) is a debt instrument whose value is based on the value of a single equity security, basket of equity securities or an index of equity securities (each, an Underlying Equity). An ELN typically provides interest income, thereby offering a yield advantage over investing directly in an Underlying Equity. The Fund may purchase ELNs that trade on a securities exchange or those that trade on the over-the-counter markets, including Rule 144A securities. The Fund may also purchase ELNs in a privately negotiated transaction with the issuer of the ELNs (or its broker-dealer affiliate). The Fund may or may not hold an ELN until its maturity.

Equity-linked securities also include issues such as Structured Yield Product Exchangeable for Stock (STRYPES), Trust Automatic Common Exchange Securities (TRACES), Trust Issued Mandatory Exchange Securities (TIMES) and Trust Enhanced Dividend Securities (TRENDS). The issuers of these equity-linked securities generally purchase and hold a portfolio of stripped U.S. Treasury securities maturing on a quarterly basis through the conversion date, and a forward purchase contract with an existing shareholder of the company relating to the common stock. Quarterly distributions on such equity-linked securities generally consist of the cash received from the U.S. Treasury securities and such equity-linked securities generally are not entitled to any dividends that may be declared on the common stock.

Foreign Currency Transactions

Because investments in foreign securities usually involve currencies of foreign countries and because a Fund may hold cash and cash equivalent investments in foreign currencies, the value of a Fund’s assets as measured in U.S. dollars may be affected favorably or unfavorably by changes in currency exchange rates and exchange control regulations. Also, a Fund may incur costs in connection with conversions between various currencies. Currency exchange rates may fluctuate significantly over short periods of time, causing a Fund’s NAV to fluctuate. Currency exchange rates are generally determined by the forces of supply and demand in the foreign exchange markets, actual or anticipated changes in interest rates, and other complex factors. Currency exchange rates also can be affected by the intervention of U.S. or foreign governments or central banks, or the failure to intervene, or by currency controls or political developments.

Spot Rates and Derivative Instruments . A Fund may conduct its foreign currency exchange transactions either at the spot (cash) rate prevailing in the foreign currency exchange market or by entering into forward foreign currency exchange contracts (forward contracts). (See Types of Investments – Derivatives .) These contracts are traded in the interbank market conducted directly between currency traders (usually large commercial banks) and their customers. Because foreign currency transactions occurring in the interbank market might involve substantially larger amounts than those involved in the use of such derivative instruments, a Fund could be disadvantaged by having to deal in the odd lot market for the underlying foreign currencies at prices that are less favorable than for round lots.

A Fund may enter into forward contracts for a variety of reasons, including for risk management (hedging) or for investment purposes.

When a Fund enters into a contract for the purchase or sale of a security denominated in a foreign currency or has been notified of a dividend or interest payment, it may desire to lock in the price of the security or the amount of the payment, usually in U.S. dollars, although it could desire to lock in the price of the security in another currency. By entering into a forward contract, a Fund would be able to protect itself against a possible loss resulting from an adverse change in the relationship between different currencies from the date the security is purchased or sold to the date on which payment is made or received or when the dividend or interest is actually received.

A Fund may enter into forward contracts when management of the Fund believes the currency of a particular foreign country may decline in value relative to another currency. When selling currencies forward in this fashion, a Fund may seek to hedge the value of foreign securities it holds against an adverse move in exchange rates. The precise matching of forward

- 27 -

Table of Contents

contract amounts and the value of securities involved generally will not be possible since the future value of securities in foreign currencies more than likely will change between the date the forward contract is entered into and the date it matures. The projection of short-term currency market movements is extremely difficult and successful execution of a short-term hedging strategy is highly uncertain.

This method of protecting the value of a Fund’s securities against a decline in the value of a currency does not eliminate fluctuations in the underlying prices of the securities. It simply establishes a rate of exchange that can be achieved at some point in time. Although forward contracts can be used to minimize the risk of loss due to a decline in value of hedged currency, they will also limit any potential gain that might result should the value of such currency increase.

A Fund may also enter into forward contracts when the Fund’s portfolio manager believes the currency of a particular country will increase in value relative to another currency. A Fund may buy currencies forward to gain exposure to a currency without incurring the additional costs of purchasing securities denominated in that currency.

For example, the combination of U.S. dollar-denominated instruments with long forward currency exchange contracts creates a position economically equivalent to a position in the foreign currency, in anticipation of an increase in the value of the foreign currency against the U.S. dollar. Conversely, the combination of U.S. dollar-denominated instruments with short forward currency exchange contracts is economically equivalent to borrowing the foreign currency for delivery at a specified date in the future, in anticipation of a decrease in the value of the foreign currency against the U.S. dollar.

This strategy may also be employed by other Funds. Unanticipated changes in the currency exchange results could result in poorer performance for Funds that enter into these types of transactions.

A Fund may designate cash or securities in an amount equal to the value of the Fund’s total assets committed to consummating forward contracts entered into under the circumstance set forth above. If the value of the securities declines, additional cash or securities will be designated on a daily basis so that the value of the cash or securities will equal the amount of the Fund’s commitments on such contracts.

At maturity of a forward contract, a Fund may either deliver (if a contract to sell) or take delivery of (if a contract to buy) the foreign currency or terminate its contractual obligation by entering into an offsetting contract with the same currency trader, having the same maturity date, and covering the same amount of foreign currency.

If a Fund engages in an offsetting transaction, it will incur a gain or loss to the extent there has been movement in forward contract prices. If a Fund engages in an offsetting transaction, it may subsequently enter into a new forward contract to buy or sell the foreign currency.

Although a Fund values its assets each business day in terms of U.S. dollars, it may not intend to convert its foreign currencies into U.S. dollars on a daily basis. However, it will do so from time to time, and such conversions involve certain currency conversion costs. Although foreign exchange dealers do not charge a fee for conversion, they do realize a profit based on the difference (spread) between the prices at which they buy and sell various currencies. Thus, a dealer may offer to sell a foreign currency to a Fund at one rate, while offering a lesser rate of exchange should a Fund desire to resell that currency to the dealer.

It is possible, under certain circumstances, including entering into forward currency contracts for investment purposes, that a Fund will be required to limit or restructure its forward contract currency transactions to qualify as a “regulated investment company” under the Internal Revenue Code.

Options on Foreign Currencies . A Fund may buy put and call options and write covered call and cash-secured put options on foreign currencies for hedging purposes and to gain exposure to foreign currencies. For example, a decline in the dollar value of a foreign currency in which securities are denominated will reduce the dollar value of such securities, even if their value in the foreign currency remains constant. In order to protect against the diminutions in the value of securities, a Fund may buy put options on the foreign currency. If the value of the currency does decline, a Fund would have the right to sell the currency for a fixed amount in dollars and would thereby offset, in whole or in part, the adverse effect on its portfolio that otherwise would have resulted.

Conversely, where a change in the dollar value of a currency would increase the cost of securities a Fund plans to buy, or where a Fund would benefit from increased exposure to the currency, a Fund may buy call options on the foreign currency, giving it the right to purchase the currency for a fixed amount in dollars. The purchase of the options could offset, at least partially, the changes in exchange rates.

As in the case of other types of options, however, the benefit to a Fund derived from purchases of foreign currency options would be reduced by the amount of the premium and related transaction costs. In addition, where currency exchange rates do not move in the direction or to the extent anticipated, a Fund could sustain losses on transactions in foreign currency options that would require it to forego a portion or all of the benefits of advantageous changes in rates.

Table of Contents

A Fund may write options on foreign currencies for similar purposes. For example, when a Fund anticipates a decline in the dollar value of foreign-denominated securities due to adverse fluctuations in exchange rates, it could, instead of purchasing a put option, write a call option on the relevant currency, giving the option holder the right to purchase that currency from the Fund for a fixed amount in dollars. If the expected decline occurs, the option would most likely not be exercised and the diminution in value of securities would be offset, at least partially, by the amount of the premium received.

Similarly, instead of purchasing a call option when a foreign currency is expected to appreciate, a Fund could write a put option on the relevant currency, giving the option holder the right to that currency from the Fund for a fixed amount in dollars. If rates move in the manner projected, the put option would expire unexercised and allow the Fund to hedge increased cost up to the amount of the premium.

As in the case of other types of options, however, the writing of a foreign currency option will constitute only a partial hedge up to the amount of the premium, and only if rates move in the expected direction. If this does not occur, the option may be exercised and the Fund would be required to buy or sell the underlying currency at a loss that may not be offset by the amount of the premium. Through the writing of options on foreign currencies, the Fund also may be required to forego all or a portion of the benefits that might otherwise have been obtained from favorable movements on exchange rates.

An option written on foreign currencies is covered if a Fund holds currency sufficient to cover the option or has an absolute and immediate right to acquire that currency without additional cash consideration upon conversion of assets denominated in that currency or exchange of other currency held in its portfolio. An option writer could lose amounts substantially in excess of its initial investments, due to the margin and collateral requirements associated with such positions.

Options on foreign currencies are traded through financial institutions acting as market-makers, although foreign currency options also are traded on certain national securities exchanges, such as the Philadelphia Stock Exchange and the Chicago Board Options Exchange, subject to SEC regulation. In an over-the-counter trading environment, many of the protections afforded to exchange participants will not be available. For example, there are no daily price fluctuation limits, and adverse market movements could therefore continue to an unlimited extent over a period of time. Although the purchaser of an option cannot lose more than the amount of the premium plus related transaction costs, this entire amount could be lost.

Foreign currency option positions entered into on a national securities exchange are cleared and guaranteed by the OCC, thereby reducing the risk of counterparty default. Further, a liquid secondary market in options traded on a national securities exchange may be more readily available than in the over-the-counter market, potentially permitting a Fund to liquidate open positions at a profit prior to exercise or expiration, or to limit losses in the event of adverse market movements.

Foreign Currency Futures and Related Options . A Fund may enter into currency futures contracts to buy or sell currencies. It also may buy put and call options and write covered call and cash-secured put options on currency futures. Currency futures contracts are similar to currency forward contracts, except that they are traded on exchanges (and have margin requirements) and are standardized as to contract size and delivery date. Most currency futures call for payment of delivery in U.S. dollars. A Fund may use currency futures for the same purposes as currency forward contracts, subject to CFTC limitations.

Currency futures and options on futures values can be expected to correlate with exchange rates, but will not reflect other factors that may affect the value of the Fund’s investments. A currency hedge, for example, should protect a Yen-denominated bond against a decline in the Yen, but will not protect a Fund against price decline if the issuer’s creditworthiness deteriorates. Because the value of a Fund’s investments denominated in foreign currency will change in response to many factors other than exchange rates, it may not be possible to match the amount of a forward contract to the value of a Fund’s investments denominated in that currency over time.

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with foreign currency transactions include: Derivatives Risk, Interest Rate Risk, and Liquidity Risk.

Foreign Securities

Foreign securities include debt, equity and derivative securities that a Fund’s portfolio manager, as the case may be, 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. A Fund’s investments in foreign markets, may include issuers in emerging markets, as well as frontier markets, each of which carry heightened risks as compared with investments in other typical foreign markets. Frontier market countries generally have smaller economies and even less developed capital markets than typical emerging market countries (which themselves have increased investment risk relative to investing in more developed markets) and, as a result, the risks of investing in emerging market countries are magnified in frontier market countries. 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 Types of Investments – Variable- and Floating-Rate Obligations, Types of Investments – Zero-Coupon, Pay-in-Kind and Step-Coupon Securities and Types of Investments – Private Placement and Other Restricted Securities for more information.

Due to the potential for foreign withholding taxes, MSCI publishes two versions of its indices reflecting the reinvestment of dividends using two different methodologies: gross dividends and net dividends. While both versions reflect reinvested dividends, they differ with respect to the manner in which taxes associated with dividend payments are treated. In calculating the net dividends version, MSCI incorporates reinvested dividends applying the withholding tax rate applicable to foreign non-resident institutional investors that do not benefit from double taxation treaties. The Investment Manager believes that the net dividends version of MSCI indices better reflects the returns U.S. investors might expect were they to invest directly in the component securities of an MSCI index.

There is a practice in certain foreign markets under which an issuer’s securities are blocked from trading at the custodian or sub-custodian level for a specified number of days before and, in certain instances, after a shareholder meeting where such shares are voted. This is referred to as “share blocking”. The blocking period can last up to several weeks. Share blocking may prevent a Fund from buying or selling securities during this period, because during the time shares are blocked, trades in such securities will not settle. It may be difficult or impossible to lift blocking restrictions, with the particular requirements varying widely by country. As a consequence of these restrictions, the Investment Manager, on behalf of a Fund, may abstain from voting proxies in markets that require share blocking.

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. A 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 interest holder 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.

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with foreign securities include: Emerging Markets Securities Risk, Foreign Currency Risk, Foreign Securities Risk, Frontier Market Risk, Issuer Risk and Market Risk.

Guaranteed Investment Contracts (Funding Agreements)

Guaranteed investment contracts, or funding agreements, are short-term, privately placed debt instruments issued by insurance companies. Pursuant to such contracts, a Fund may make cash contributions to a deposit fund of the insurance company’s general account. The insurance company then credits to a Fund payments at negotiated, floating or fixed interest rates. A Fund will purchase guaranteed investment contracts only from issuers that, at the time of purchase, meet certain credit and quality standards. In general, guaranteed investment contracts are not assignable or transferable without the permission of the issuing insurance companies, and an active secondary market does not exist for these investments. In addition, the issuer may not be able to pay the principal amount to a Fund on seven days’ notice or less, at which time the investment may be considered illiquid under applicable SEC regulatory guidance and subject to certain restrictions. See Types of Investments – Illiquid Securities.

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with guaranteed investment contracts (funding agreements) include: Credit Risk and Liquidity Risk.

Illiquid Securities

Illiquid securities are defined by a Fund consistent with the 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 a 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. Some securities are deemed to be illiquid because they are subject to contractual or legal restrictions on resale. Subject to its investment policies, a Fund may invest

- 30 -

Table of Contents

in illiquid investments and may invest in certain restricted securities that are deemed to be illiquid securities. To the extent a fund invests in illiquid or restricted securities, it may encounter difficulty in determining a market value for the securities. Disposing of illiquid or restricted securities may involve time-consuming negotiations and legal expense, and it may be difficult or impossible for a fund to sell the investment promptly and at an acceptable price.

Although one or more of the other risks described in this SAI may also apply, the risk typically associated with illiquid securities include: Liquidity Risk.

Initial Public Offerings

A 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. A 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 a Fund’s performance while the Fund’s assets are relatively small. The impact of an IPO on a Fund’s performance may tend to diminish as the Fund’s assets grow. In circumstances when investments in IPOs make a significant contribution to a Fund’s performance, there can be no assurance that similar contributions from IPOs will continue in the future.

Although one or more risks described in this SAI may also apply, the risks typically associated with IPOs include: Initial Public Offering (IPO) Risk, Issuer risk, Liquidity Risk, Market Risk and Small Company Securities Risk.

Inflation Protected Securities

Inflation is a general rise in prices of goods and services. Inflation erodes the purchasing power of an investor’s assets. For example, if an investment provides a total return of 7% in a given year and inflation is 3% during that period, the inflation-adjusted, or real, return is 4%. Inflation-protected securities are debt securities whose principal and/or interest payments are adjusted for inflation, unlike debt securities that make fixed principal and interest payments. One type of inflation-protected debt security is issued by the U.S. Treasury. The principal of these securities is adjusted for inflation as indicated by the Consumer Price Index (CPI) for urban consumers and interest is paid on the adjusted amount. The CPI is a measurement of changes in the cost of living, made up of components such as housing, food, transportation and energy.

If the CPI falls, the principal value of inflation-protected securities will be adjusted downward, and consequently the interest payable on these securities (calculated with respect to a smaller principal amount) will be reduced. Conversely, if the CPI rises, the principal value of inflation-protected securities will be adjusted upward, and consequently the interest payable on these securities will be increased. Repayment of the original bond principal upon maturity is guaranteed in the case of U.S. Treasury inflation-protected securities, even during a period of deflation. However, the current market value of the inflation-protected securities is not guaranteed and will fluctuate. Other inflation-indexed securities include inflation-related bonds, which may or may not provide a similar guarantee. If a guarantee of principal is not provided, the adjusted principal value of the bond repaid at maturity may be less than the original principal.

Other issuers of inflation-protected debt securities include other U.S. government agencies or instrumentalities, corporations and foreign governments. There can be no assurance that the CPI or any foreign inflation index will accurately measure the real rate of inflation in the prices of goods and services. Moreover, there can be no assurance that the rate of inflation in a foreign country will be correlated to the rate of inflation in the United States. If interest rates rise due to reasons other than inflation (for example, due to changes in currency exchange rates), investors in these securities may not be protected to the extent that the increase is not reflected in the bond’s inflation measure.

Any increase in principal for an inflation-protected security resulting from inflation adjustments is considered by IRS regulations to be taxable income in the year it occurs. For direct holders of an inflation-protected security, this means that taxes must be paid on principal adjustments even though these amounts are not received until the bond matures. Similarly, a Fund holding these securities distributes both interest income and the income attributable to principal adjustments in the form of cash or reinvested shares, which are taxable to shareholders.

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with inflation-protected securities include: Inflation Protected Securities Risk, Interest Rate Risk and Market Risk. In addition, inflation protected securities issued by non-U.S. government agencies or instrumentalities are subject to Credit Risk.

Investments in Other Investment Companies (Including ETFs)

Investing in other investment companies may be a means by which a Fund seeks to achieve its investment objective. A 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 a Fund from the SEC. These securities include shares of other open-end investment companies (i.e., mutual funds), closed-end funds, exchange-traded funds (ETFs) and business development companies.

- 31 -

Table of Contents

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 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 a fund. Such other investment companies may include ETFs, which are shares of publicly traded unit investment trusts, open-end funds or depositary receipts that may be passively managed (e.g., they seek to track the performance of specific indexes or companies in related industries) or they may be actively managed. The SEC has granted orders for exemptive relief to certain ETFs that permit investments in those ETFs by other investment companies in excess of these limits.

ETFs are listed on an exchange and trade in the secondary market on a per-share basis, which allows investors to purchase and sell ETF shares at their market price throughout the day. Certain ETFs, such as passively managed ETFs, hold portfolios of securities that are designed to replicate, as closely as possible before expenses, the price and yield of a specified market index. The performance results of these ETFs will not replicate exactly the performance of the pertinent index due to transaction and other expenses, including fees to service providers borne by ETFs. ETF shares are sold and redeemed at net asset value only in large blocks called creation units and redemption units, respectively. The Funds’ ability to redeem redemption units may be limited by the 1940 Act, which provides that ETFs will not be obligated to redeem shares held by the funds in an amount exceeding one percent of their total outstanding securities during any period of less than 30 days.

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. Because these investment companies may invest in other securities, they are also subject to the risks associated with a variety of investment instruments as described in this SAI.

Under the 1940 Act and rules and regulations thereunder, a Fund may purchase shares of affiliated 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 Ameriprise Financial and its Affiliates – Certain Conflicts of Interest.

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with the securities of other investment companies include: Exchange-Traded Fund (ETF) Risk, Investing in Other Funds Risk, Issuer Risk and Market Risk.

Low and Below Investment Grade (High Yield) Securities

Low and below investment grade securities (below investment grade securities are also known as “junk bonds”) are debt securities with the lowest investment grade rating (e.g., BBB by S&P and Fitch or Baa by Moody’s), that are below investment grade (e.g., lower than BBB by S&P and Fitch or Baa by Moody’s) or that are unrated but determined by a Fund’s portfolio manager to be of comparable quality. These types of securities may be issued to fund corporate transactions or restructurings, such as leveraged buyouts, mergers, acquisitions, debt reclassifications or similar events, are more speculative in nature than securities with higher ratings and tend to be more sensitive to credit risk, particularly during a downturn in the economy. These types of securities generally are issued by unseasoned companies without long track records of sales and earnings, or by companies or municipalities that have questionable credit strength. Low and below investment grade securities and comparable unrated securities: (i) likely will have some quality and protective characteristics that, in the judgment of one or more NRSROs, are outweighed by large uncertainties or major risk exposures to adverse conditions; (ii) are speculative with respect to the issuer’s capacity to pay interest and repay principal in accordance with the terms of the obligation; and (iii) may have a less liquid secondary market, potentially making it difficult to value or sell such securities. Credit ratings issued by credit rating agencies are designed to evaluate the safety of principal and interest payments of rated securities. They do not, however, evaluate the market value risk of lower-quality securities and, therefore, may not fully reflect the true risks of an investment. In addition, credit rating agencies may or may not make timely changes in a rating to reflect changes in the economy or in the condition of the issuer that affect the market value of the securities. Consequently, credit ratings are used only as a preliminary indicator of investment quality. Low and below investment grade 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 Types of Investments – Variable- and Floating-Rate Obligations, Types of Investments – Zero-Coupon, Pay-in-Kind and Step-Coupon Securities and Types of Investments – Private Placement and Other Restricted Securities for more information.

Table of Contents

The rates of return on these types of securities generally are higher than the rates of return available on more highly rated securities, but generally involve greater volatility of price and risk of loss of principal and income, including the possibility of default by or insolvency of the issuers of such securities. Accordingly, a Fund may be more dependent on the Investment Manager’s or a subadviser’s credit analysis with respect to these types of securities than is the case for more highly rated securities.

The market values of certain low and below investment grade securities and comparable unrated securities tend to be more sensitive to individual corporate developments and changes in economic conditions than are the market values of more highly rated securities. In addition, issuers of low and below investment grade and comparable unrated securities often are highly leveraged and may not have more traditional methods of financing available to them, so that their ability to service their debt obligations during an economic downturn or during sustained periods of rising interest rates may be impaired.

The risk of loss due to default is greater for low and below investment grade and comparable unrated securities than it is for higher rated securities because low and below investment grade securities and comparable unrated securities generally are unsecured and frequently are subordinated to more senior indebtedness. A Fund may incur additional expenses to the extent that it is required to seek recovery upon a default in the payment of principal or interest on its holdings of such securities. The existence of limited markets for lower-rated debt securities may diminish a Fund’s ability to: (i) obtain accurate market quotations for purposes of valuing such securities and calculating portfolio net asset value; and (ii) sell the securities at fair market value either to meet redemption requests or to respond to changes in the economy or in financial markets.

Many lower-rated securities are not registered for offer and sale to the public under the 1933 Act. Investments in these restricted securities may be determined to be liquid (able to be sold within seven days at approximately the price at which they are valued by a Fund) pursuant to policies approved by the Fund’s Trustees. Investments in illiquid securities, including restricted securities that have not been determined to be liquid, may not exceed 15% of a Fund’s net assets. A Fund is not otherwise subject to any limitation on its ability to invest in restricted securities. Restricted securities may be less liquid than other lower-rated securities, potentially making it difficult to value or sell such securities.

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with low and below investment grade securities include: Credit Risk, Interest Rate Risk, Low and Below Investment Grade (High Yield) Securities Risk and Prepayment and Extension Risk.

Money Market Instruments

Money market instruments include cash equivalents and short-term debt obligations which include: (i) bank obligations, including certificates of deposit (CDs), time deposits and bankers’ acceptances, and letters of credit of banks or savings and loan associations having capital surplus and undivided profits (as of the date of its most recently published annual financial statements) in excess of $100 million (or the equivalent in the instance of a foreign branch of a U.S. bank) at the date of investment; (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. A Fund may also invest in affiliated and unaffiliated money market mutual funds, which invests primarily in money market instruments. See Types of Investments – Variable- and Floating-Rate Obligations and Types of Investments – Private Placement and Other Restricted Securities for more information.

With respect to money market securities, certain U.S. Government obligations are backed or insured by the U.S. Government, its agencies or its instrumentalities. Other money market securities are backed only by the claims paying ability or creditworthiness of the issuer.

Bankers’ acceptances are marketable short-term credit instruments used to finance the import, export, transfer or storage of goods. They are termed “accepted” when a bank unconditionally guarantees their payment at maturity.

A Fund may invest its daily cash balance in Columbia Short-Term Cash Fund, a money market fund established for the exclusive use of the funds in the Columbia Fund Family and other institutional clients of the Investment Manager.

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with money market instruments include: Credit Risk, Inflation Risk, Interest Rate Risk, Issuer Risk, and Money Market Fund Risk.

Mortgage-Backed Securities

Mortgage-backed securities are a type of asset-backed security that 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

- 33 -

Table of Contents

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 Types of Investments – Variable- and Floating-Rate Obligations, Types of Investments – Zero-Coupon, Pay-in-Kind and Step-Coupon Securities and Types of 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. The U.S. Treasury has historically had the authority to purchase obligations of Fannie Mae and Freddie Mac. In addition, in 2008, due to capitalization concerns, Congress provided the U.S. Treasury with additional authority to lend Fannie Mae and Freddie Mac emergency funds and to purchase the companies’ stock, as described below. In September 2008, the U.S. Treasury and the Federal Housing Finance Agency (FHFA) announced that Fannie Mae and Freddie Mac had been placed in conservatorship.

Since 2009, Fannie Mae and Freddie Mac have received significant capital support through U.S. Treasury preferred stock purchases and Federal Reserve purchases of their mortgage-backed securities. While the Federal Reserve’s purchases have terminated, the U.S. Treasury announced in December 2009 that it would continue its support for the entities’ capital as necessary to prevent a negative net worth through at least 2012. While the U.S. Treasury is committed to offset negative equity at Fannie Mae and Freddie Mac through its preferred stock purchases through 2012, there can be no assurance that the Federal Reserve, U.S. Treasury, or FHFA initiatives discussed above will ensure that Fannie Mae and Freddie Mac will remain successful in meeting their obligations with respect to the debt and mortgage-backed securities they issue beyond that date. In addition, Fannie Mae and Freddie Mac also are the subject of several continuing class action lawsuits and investigations by federal regulators over certain accounting, disclosure or corporate governance matters, which (along with any resulting financial restatements) may adversely affect the guaranteeing entities. Importantly, the future of the entities is in serious question as the U.S. Government reportedly is considering multiple options, ranging from nationalization, privatization, consolidation, or abolishment of the entities.

Stripped mortgage-backed securities are a type of mortgage-backed security that receives differing proportions of the interest and principal payments from the underlying assets. Generally, there are two classes of stripped mortgage-backed securities: Interest Only (IO) and Principal Only (PO). IOs entitle the holder to receive distributions consisting of all or a portion of the interest on the underlying pool of mortgage loans or mortgage-backed securities. POs entitle the holder to receive distributions consisting of all or a portion of the principal of the underlying pool of mortgage loans or mortgage-backed securities. See Types of Investments – Stripped Securities for more information.

Collateralized Mortgage Obligations (CMOs) are hybrid mortgage-related instruments issued by special purpose entities secured by pools of mortgage loans or other mortgage-related securities, such as mortgage pass-through securities or stripped mortgage-backed securities. CMOs may be structured into multiple classes, often referred to as “tranches,” with each class bearing a different stated maturity and entitled to a different schedule for payments of principal and interest, including prepayments. Principal prepayments on collateral underlying a CMO may cause it to be retired substantially earlier than its stated maturity or final distribution dates, resulting in a loss of all or part of the premium if any has been paid. The yield characteristics of mortgage-backed securities differ from those of other debt securities. Among the differences are that interest and principal payments are made more frequently on mortgage-backed securities, usually monthly, and principal may be repaid at any time. These factors may reduce the expected yield. 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.

Commercial mortgage-backed securities (CMBS) are a specific type of mortgage-backed security collateralized by a pool of mortgages on commercial real estate.

Table of Contents

CMO Residuals are mortgage securities issued by agencies or instrumentalities of the U.S. Government or by private originators of, or investors in, mortgage loans, including savings and loan associations, homebuilders, mortgage banks, commercial banks, investment banks and special purpose entities of the foregoing. The cash flow generated by the mortgage assets underlying a series of CMOs is applied first to make required payments of principal and interest on the CMOs and second to pay the related administrative expenses and any management fee of the issuer. The residual in a CMO structure generally represents the interest in any excess cash flow remaining after making the foregoing payments. Each payment of such excess cash flow to a holder of the related CMO residual represents income and/or a return of capital. The amount of residual cash flow resulting from a CMO will depend on, among other things, the characteristics of the mortgage assets, the coupon rate of each class of CMO, prevailing interest rates, the amount of administrative expenses and the pre-payment experience on the mortgage assets. In particular, the yield to maturity on CMO residuals is extremely sensitive to pre-payments on the related underlying mortgage assets, in the same manner as an interest-only (“IO”) class of stripped mortgage-backed securities. In addition, if a series of a CMO includes a class that bears interest at an adjustable rate, the yield to maturity on the related CMO residual will also be extremely sensitive to changes in the level of the index upon which interest rate adjustments are based. As described below with respect to stripped mortgage-backed securities, in certain circumstances an ETF may fail to recoup fully its initial investment in a CMO residual. CMO residuals are generally purchased and sold by institutional investors through several investment banking firms acting as brokers or dealers. Transactions in CMO residuals are generally completed only after careful review of the characteristics of the securities in question. In addition, CMO residuals may, or pursuant to an exemption therefrom, may not have been registered under the 1933 Act. CMO residuals, whether or not registered under the 1933 Act, may be subject to certain restrictions on transferability, and may be deemed “illiquid” and subject to a Fund’s limitations on investment in illiquid securities.

Mortgage Pass-Through Securities Interests in pools of mortgage-related securities differ from other forms of debt securities, which normally provide for periodic payment of interest in fixed amounts with principal payments at maturity or specified call dates. Instead, these securities provide a monthly payment which consists of both interest and principal payments. In effect, these payments are a “pass-through” of the monthly payments made by the individual borrowers on their residential or commercial mortgage loans, net of any fees paid to the issuer or guarantor of such securities. Additional payments are caused by repayments of principal resulting from the sale of the underlying property, refinancing or foreclosure, net of fees or costs which may be incurred. Some mortgage-related securities (such as securities issued by the GNMA) are described as “modified pass-through.” These securities entitle the holder to receive all interest and principal payments owed on the mortgage pool, net of certain fees, at the scheduled payment dates regardless of whether or not the mortgagor actually makes the payment.

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.

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with mortgage and asset-backed securities include: Credit Risk, Interest Rate Risk, Issuer Risk, Liquidity Risk, Mortgage-Backed and Other Asset Backed Securities Risk, Prepayment and Extension Risk and Reinvestment Risk.

Municipal Securities

Municipal securities include debt obligations issued by governmental entities to obtain funds for various public purposes, including the construction of a wide range of public facilities, the refunding of outstanding obligations, the payment of general operating expenses, and the extension of loans to public institutions and facilities.

Municipal securities may include municipal bonds, municipal notes and municipal leases, which are described below. Municipal bonds are debt obligations of a governmental entity that obligate the municipality to pay the holder a specified sum of money at specified intervals and to repay the principal amount of the loan at maturity. Municipal securities can be classified into two principal categories, including “general obligation” bonds and other securities and “revenue” bonds and other securities. General obligation bonds are secured by the issuer’s full faith, credit and taxing power for the payment of principal and interest. Revenue securities are payable only from the revenues derived from a particular facility or class of facilities or, in some cases, from the proceeds of a special excise tax or other specific revenue source, such as the user of the facility being financed. Municipal securities also may include “moral obligation” securities, which normally are issued by special purpose public authorities. If the issuer of moral obligation securities is unable to meet its debt service obligations from current revenues, it may draw on a reserve fund, the restoration of which is a moral commitment but not a legal obligation of the governmental entity that created the special purpose public authority. Municipal 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 Types of Investments –Variable- and Floating-Rate Obligations, Types of Investments – Zero-Coupon, Pay-in-Kind and Step-Coupon Securities and Types of Investments – Private Placement and Other Restricted Securities for more information.

Municipal notes may be issued by governmental entities and other tax-exempt issuers in order to finance short-term cash needs or, occasionally, to finance construction. Most municipal notes are general obligations of the issuing entity payable

- 35 -

Table of Contents

from taxes or designated revenues expected to be received within the relevant fiscal period. Municipal notes generally have maturities of one year or less. Municipal notes can be subdivided into two sub-categories: (i) municipal commercial paper and (ii) municipal demand obligations.

Municipal commercial paper typically consists of very short-term unsecured negotiable promissory notes that are sold, for example, to meet seasonal working capital or interim construction financing needs of a governmental entity or agency. While these obligations are intended to be paid from general revenues or refinanced with long-term debt, they frequently are backed by letters of credit, lending agreements, note repurchase agreements or other credit facility agreements offered by banks or institutions. See Types of Investments – Commercial Paper for more information.

Municipal demand obligations can be subdivided into two general types: variable rate demand notes and master demand obligations. Variable rate demand notes are tax-exempt municipal obligations or participation interests that provide for a periodic adjustment in the interest rate paid on the notes. They permit the holder to demand payment of the notes, or to demand purchase of the notes at a purchase price equal to the unpaid principal balance, plus accrued interest either directly by the issuer or by drawing on a bank letter of credit or guaranty issued with respect to such note. The issuer of the municipal obligation may have a corresponding right to prepay at its discretion the outstanding principal of the note plus accrued interest upon notice comparable to that required for the holder to demand payment. The variable rate demand notes in which a Fund may invest are payable, or are subject to purchase, on demand, usually on notice of seven calendar days or less. The terms of the notes generally provide that interest rates are adjustable at intervals ranging from daily to six months.

Master demand obligations are tax-exempt municipal obligations that provide for a periodic adjustment in the interest rate paid and permit daily changes in the amount borrowed. The interest on such obligations is, in the opinion of counsel for the borrower, excluded from gross income for federal income tax purposes (but not necessarily for alternative minimum tax purposes). Although there is no secondary market for master demand obligations, such obligations are considered by a Fund to be liquid because they are payable upon demand.

Municipal lease obligations are participations in privately arranged loans to state or local government borrowers and may take the form of a lease, an installment purchase, or a conditional sales contract. They are issued by state and local governments and authorities to acquire land, equipment, and facilities. An investor may purchase these obligations directly, or it may purchase participation interests in such obligations. In general, municipal lease obligations are unrated, in which case they will be determined by a Fund’s Portfolio Manager to be of comparable quality at the time of purchase to rated instruments that may be acquired by a Fund. Frequently, privately arranged loans have variable interest rates and may be backed by a bank letter of credit. In other cases, they may be unsecured or may be secured by assets not easily liquidated. Moreover, such loans in most cases are not backed by the taxing authority of the issuers and may have limited marketability or may be marketable only by virtue of a provision requiring repayment following demand by the lender.

Municipal leases may be subject to greater risks than general obligation or revenue bonds. State constitutions and statutes set forth requirements that states or municipalities must meet in order to issue municipal obligations. Municipal leases may contain a covenant by the state or municipality to budget for and make payments due under the obligation. Certain municipal leases may, however, provide that the issuer is not obligated to make payments on the obligation in future years unless funds have been appropriated for this purpose each year.

Although lease obligations do not constitute general obligations of the municipal issuer to which the government’s taxing power is pledged, a lease obligation ordinarily is backed by the government’s covenant to budget for, appropriate, and make the payments due under the lease obligation. However, certain lease obligations contain “non-appropriation” clauses that provide that the government has no obligation to make lease or installment purchase payments in future years unless money is appropriated for such purpose on a periodic basis. In the case of a “non-appropriation” lease, a Fund’s ability to recover under the lease in the event of non-appropriation or default likely will be limited to the repossession of the leased property in the event that foreclosure proves difficult.

Tender option bonds are municipal securities having relatively long maturities and bearing interest at a fixed interest rate substantially higher than prevailing short-term tax-exempt rates that is coupled with the agreement of a third party, such as a bank, broker-dealer or other financial institution, to grant the security holders the option, at periodic intervals, to tender their securities to the institution and receive the face value thereof. The financial institution receives periodic fees equal to the difference between the municipal security’s coupon rate and the rate that would cause the security to trade at face value on the date of determination.

There are variations in the quality of municipal securities, both within a particular classification and between classifications, and the rates of return on municipal securities can depend on a variety of factors, including general money market conditions, the financial condition of the issuer, general conditions of the municipal bond market, the size of a particular offering, the maturity of the obligation, and the rating of the issue. The ratings of NRSROs represent their opinions as to the quality of municipal securities. It should be emphasized, however, that these ratings are general and are not absolute standards of quality, and municipal securities with the same maturity, interest rate, and rating may have

different rates of return while municipal securities of the same maturity and interest rate with different ratings may have the same rate of return. The municipal bond market is characterized by a large number of different issuers, many having smaller sized bond issues, and a wide choice of different maturities within each issue. For these reasons, most municipal bonds do not trade on a daily basis and many trade only rarely. Because many of these bonds trade infrequently, the spread between the bid and offer may be wider and the time needed to develop a bid or an offer may be longer than for other security markets. See Appendix A for a discussion of securities ratings. (See Types of Investments – Debt Obligations .)

Standby Commitments. Standby commitments are securities under which a purchaser, usually a bank or broker-dealer, agrees to purchase, for a fee, an amount of a Fund’s municipal obligations. The amount payable by a bank or broker-dealer to purchase securities subject to a standby commitment typically will be substantially the same as the value of the underlying municipal securities. A Fund may pay for standby commitments either separately in cash or by paying a higher price for portfolio securities that are acquired subject to such a commitment.

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with standby commitments include: Counterparty Risk, Market Risk and Municipal Securities Risk.

Taxable Municipal Obligations. Interest or other investment return is subject to federal income tax for certain types of municipal obligations for a variety of reasons. These municipal obligations do not qualify for the federal income tax exemption because (a) they did not receive necessary authorization for tax-exempt treatment from state or local government authorities, (b) they exceed certain regulatory limitations on the cost of issuance for tax-exempt financing or (c) they finance public or private activities that do not qualify for the federal income tax exemption. These non-qualifying activities might include, for example, certain types of multi-family housing, certain professional and local sports facilities, refinancing of certain municipal debt, and borrowing to replenish a municipality’s underfunded pension plan.

For more information about the key risks associated with investments in states, see Appendix D. See Appendix A for a discussion of securities ratings. (See Types of Investments – Debt Obligations .)

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with municipal securities include: Credit Risk, Inflation Risk, Interest Rate Risk, Market Risk, Municipal Securities Risk and Municipal Securities Risk/Health Care Sector Risk.

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 a 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 a 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 Types of Investments – Variable- and Floating-Rate Obligations, Types of Investments – Zero-Coupon, Pay-in-Kind and Step-Coupon Securities and Types of Investments – Private Placement and Other Restricted Securities for more information.

Loan participations also are a type of participation interest. Loans, loan participations, and interests in securitized loan pools are interests in amounts owed by a corporate, governmental, or other borrower to a lender or consortium of lenders (typically banks, insurance companies, investment banks, government agencies, or international agencies).

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with loan participations include: Credit Risk and Interest Rate Risk.

Partnership Securities

The Fund may invest in securities issued by publicly traded partnerships or master limited partnerships or limited liability companies (together referred to as “PTPs/MLPs”). These entities are limited partnerships or limited liability companies that may be publicly traded on stock exchanges or markets such as the NYSE, the NYSE Alternext US LLC (“NYSE Alternext”) (formerly the American Stock Exchange) and NASDAQ. PTPs/MLPs often own businesses or properties relating to energy, natural resources or real estate, or may be involved in the film industry or research and development activities. Generally PTPs/MLPs are operated under the supervision of one or more managing partners or members. Limited partners, unit holders, or members (such as a fund that invests in a partnership) are not involved in the day-to-day management of the company. Limited partners, unit holders, or members are allocated income and capital gains associated with the partnership project in accordance with the terms of the partnership or limited liability company agreement.

Table of Contents

At times PTPs/MLPs may potentially offer relatively high yields compared to common stocks. Because PTPs/MLPs are generally treated as partnerships or similar limited liability “pass-through” entities for tax purposes, they do not ordinarily pay income taxes, but pass their earnings on to unit holders (except in the case of some publicly traded firms that may be taxed as corporations). For tax purposes, unit holders may initially be deemed to receive only a portion of the distributions attributed to them because certain other portions may be attributed to the repayment of initial investments and may thereby lower the cost basis of the units or shares owned by unit holders. As a result, unit holders may effectively defer taxation on the receipt of some distributions until they sell their units. These tax consequences may differ for different types of entities.

Although the high yields potentially offered by these investments may be attractive, PTPs/MLPs have some disadvantages and present some risks. Investors in a partnership or limited liability company may have fewer protections under state law than do investors in a corporation. Distribution and management fees may be substantial. Losses are generally considered passive and cannot offset income other than income or gains relating to the same entity. These tax consequences may differ for different types of entities. Many PTPs/MLPs may operate in certain limited sectors such as, without limitation, energy, natural resources, and real estate, which may be volatile or subject to periodic downturns. Growth may be limited because most cash is paid out to unit holders rather than retained to finance growth. The performance of PTPs/MLPs may be partly tied to interest rates. Rising interest rates, a poor economy, or weak cash flows are among the factors that can pose significant risks for investments in PTPs/MLPs. Investments in PTPs/MLPs also may be relatively illiquid at times.

The fund may also invest in relatively illiquid securities issued by limited partnerships or limited liability companies that are not publicly traded. These securities, which may represent investments in certain areas such as real estate or private equity, may present many of the same risks of PTPs/MLPs. In addition, they may present other risks including higher management and distribution fees, uncertain cash flows, potential calls for additional capital, and very limited liquidity.

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with partnership securities include: Interest Rate Risk, Issuer Risk, Liquidity Risk and Market Risk.

Preferred Stock

Preferred stock represents units of ownership of a corporation that frequently have dividends that are set at a specified rate. Preferred stock has preference over common stock in the payment of dividends and the liquidation of assets. Preferred stock shares some of the characteristics of both debt and equity. Preferred stock ordinarily does not carry voting rights. Most preferred stock is cumulative; if dividends are passed (i.e., not paid for any reason), they accumulate and must be paid before common stock dividends. Participating preferred stock entitles its holders to share in profits above and beyond the declared dividend, along with common shareholders, as distinguished from nonparticipating preferred stock, which is limited to the stipulated dividend. Convertible preferred stock is exchangeable for a given number of shares of common stock and thus tends to be more volatile than nonconvertible preferred stock, which generally behaves more like a fixed income bond. Preferred stock may be privately placed or publicly offered. The price of a preferred stock is generally determined by earnings, type of products or services, projected growth rates, experience of management, liquidity, and general market conditions of the markets on which the stock trades. See Types of Investments – Private Placement and Other Restricted Securities for more information.

Auction preferred stock (APS) is a type of adjustable-rate preferred stock with a dividend determined periodically in a Dutch auction process by corporate bidders. An APS is distinguished from standard preferred stock because its dividends change from time to time. Shares typically are bought and sold at face values generally ranging from $100,000 to $500,000 per share.

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with preferred stock include: Convertible Securities Risk, Issuer Risk and Market Risk.

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

- 38 -

Table of Contents

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.

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with private placement and other restricted securities include: Issuer Risk, Liquidity Risk and Market Risk

Real Estate Investment Trusts

Real estate investment trusts (REITs) are pooled investment vehicles that manage a portfolio of real estate or real estate related loans to earn profits for their shareholders. REITs are generally classified as equity REITs, mortgage REITs or a combination of equity and mortgage REITs. Equity REITs invest the majority of their assets directly in real property, such as shopping centers, nursing homes, office buildings, apartment complexes, and hotels, and derive income primarily from the collection of rents. Equity REITs can also realize capital gains by selling properties that have appreciated in value. Mortgage REITs invest the majority of their assets in real estate mortgages and derive income from the collection of interest payments. REITs can be subject to extreme volatility due to fluctuations in the demand for real estate, changes in interest rates, and adverse economic conditions.

Partnership units of real estate and other types of companies sometimes are organized as master limited partnerships in which ownership interests are publicly traded.

Similar to investment companies, REITs are not taxed on income distributed to shareholders provided they comply with certain requirements under the Code. The failure of a REIT to continue to qualify as a REIT for tax purposes can materially affect its value. A Fund will indirectly bear its proportionate share of any expenses paid by a REIT in which it invests. REITs often do not provide complete tax information until after the calendar year-end. Consequently, because of the delay, it may be necessary for a Fund investing in REITs to request permission to extend the deadline for issuance of Forms 1099-DIV beyond January 31. In the alternative, amended Forms 1099-DIV may be sent.

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with REITs include: Interest Rate Risk, Issuer Risk, Market Risk and Real Estate-Related Investment Risk.

Repurchase Agreements

Repurchase agreements are agreements under which a Fund acquires a security for a relatively short period of time (usually within seven days) subject to the obligation of a seller to repurchase and a Fund to resell such security at a fixed time and price (representing a Fund’s cost plus interest). The repurchase agreement specifies the yield during the purchaser’s holding period. Repurchase agreements also may be viewed as loans made by a Fund that are collateralized by the securities subject to repurchase, which may consist of a variety of security types. A 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.

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with repurchase agreements include: Counterparty Risk, Credit Risk, Issuer Risk, Market Risk and Repurchase Agreements Risk.

Reverse Repurchase Agreements

Reverse repurchase agreements are agreements under which a Fund temporarily transfers possession of a portfolio instrument to another party, such as a bank or broker-dealer, in return for cash. At the same time, the Fund agrees to repurchase the instrument at an agreed-upon time (normally within 7 days) and price which reflects an interest payment. A Fund generally retains the right to interest and principal payments on the security. Reverse repurchase agreements also may be viewed as borrowings made by a Fund.

Short Sales

A 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 a 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, a 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. A 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 a Fund, because a 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 below regarding short sales not “against the box.” However, when a Fund sells short “against the box” it typically limits the amount of securities that it has leveraged. A Fund’s decision to make a short sale “against the box” may be a technique to hedge against market risks when a Fund’s portfolio manager believes that the price of a security may decline, causing a decline in the value of a security owned by a Fund or a security convertible into or exchangeable for such security. In such case, any future losses in a 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 relative to the amount of the securities a Fund owns, either directly or indirectly, and, in the case where a Fund owns convertible securities, changes in the investment values or conversion premiums of such securities. Short sales may have adverse tax consequences to a Fund and its shareholders.

Subject to its fundamental and non-fundamental investment policies, a Fund may engage in short sales that are not “against the box,” which are sales by a Fund of securities, contracts or instruments that it does not own in hopes of purchasing the same security, contract or instrument 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, commodity futures contract or other instrument. To make delivery to the buyer, a Fund must borrow or purchase the security. If borrowed, a Fund is then obligated to replace the security borrowed from the third party, so a 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 a 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, a 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, a 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 of forward commitments and derivatives do not involve borrowing a security. These types of short sales may include futures, options, contracts for differences, forward contracts on financial instruments and options such as contracts, credit-linked instruments, and swap contracts.

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with short sales include: Leverage Risk, Market Risk and Short Selling Risk.

Sovereign Debt

Sovereign debt obligations are issued or guaranteed by foreign governments or their agencies. It may be in the form of conventional securities or other types of debt instruments such as loans or loan participations. A sovereign debtor’s willingness or ability to repay principal and pay interest in a timely manner may be affected by a variety of factors, including its cash flow situation, the extent of its reserves, the availability of sufficient foreign exchange on the date a payment is due, the relative size of the debt service burden to the economy as a whole, the sovereign debtor’s policy toward international lenders, and the political constraints to which a sovereign debtor may be subject. (See also Types of Investments – Foreign Securities .) In addition, there may be no legal recourse against a sovereign debtor in the event of a default.

Sovereign debt includes Brady Bonds, which are securities issued under the framework of the Brady Plan, an initiative announced by former U.S. Treasury Secretary Nicholas F. Brady in 1989 as a mechanism for debtor nations to restructure their outstanding external commercial bank indebtedness.

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with sovereign debt include: Credit Risk, Emerging Markets Securities Risk, Foreign Securities Risk, Issuer Risk and Market Risk.

Stripped Securities

Stripped securities are the separate income or principal payments of a debt security and evidence ownership in either the future interest or principal payments on an instrument. There are many different types and variations of stripped securities. For example, Separate Trading of Registered Interest and Principal Securities (STRIPS) can be component parts of a U.S. Treasury security where the principal and interest components are traded independently through DTC, a clearing agency registered pursuant to Section 17A of the 1934 Act and created to hold securities for its participants, and to facilitate the clearance and settlement of securities transactions between participants through electronic computerized book-entries, thereby eliminating the need for physical movement of certificates. Treasury Investor Growth Receipts (TIGERs) are U.S. Treasury securities stripped by brokers. Stripped mortgage-backed securities, (SMBS) also can be issued by the U.S. Government or its agencies. Stripped securities may be structured as fixed-, variable- or floating-rate obligations. See Types of Investments – Variable- and Floating-Rate Obligations for more information.

SMBS usually are structured with two or more classes that receive different proportions of the interest and principal distributions from a pool of mortgage-backed assets. Common types of SMBS will be structured so that one class receives some of the interest and most of the principal from the mortgage-backed assets, while another class receives most of the interest and the remainder of the principal.

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with stripped securities include: Credit Risk, Interest Rate Risk, Liquidity Risk, Prepayment and Extension Risk and Stripped Securities Risk

Trust-Preferred Securities

Trust-preferred securities, also known as trust-issued securities, are securities that have characteristics of both debt and equity instruments and are typically treated by the Funds as debt investments.

Generally, trust-preferred securities are cumulative preferred stocks issued by a trust that is created by a financial institution, such as a bank holding company. The financial institution typically creates the trust with the objective of increasing its capital by issuing subordinated debt to the trust in return for cash proceeds that are reflected on the financial institutions balance sheet.

The primary asset owned by the trust is the subordinated debt issued to the trust by the financial institution. The financial institution makes periodic interest payments on the debt as discussed further below. The financial institution will subsequently own the trust’s common securities, which may typically represent a small percentage of the trust’s capital structure. The remainder of the trust’s capital structure typically consists of trust-preferred securities which are sold to investors. The trust uses the sales proceeds to purchase the subordinated debt issued by the financial institution. The financial institution uses the proceeds from the subordinated debt sale to increase its capital while the trust receives periodic interest payments from the financial institution for holding the subordinated debt.

The trust uses the interest received to make dividend payments to the holders of the trust-preferred securities. The dividends are generally paid on a quarterly basis and are often higher than other dividends potentially available on the financial institution’s common stocks. The interests of the holders of the trust-preferred securities are senior to those of common stockholders in the event that the financial institution is liquidated, although their interests are typically subordinated to those of other holders of other debt issued by the institution.

The primary benefit for the financial institution in using this particular structure is that the trust-preferred securities issued by the trust are treated by the financial institution as debt securities for tax purposes (as a consequence of which the expense of paying interest on the securities is tax deductible), but are treated as more desirable equity securities for purposes of the calculation of capital requirements.

In certain instances, the structure involves more than one financial institution and thus, more than one trust. In such a pooled offering, an additional separate trust may be created. This trust will issue securities to investors and use the proceeds to purchase the trust- preferred securities issued by other trust subsidiaries of the participating financial institutions. In such a structure, the trust-preferred securities held by the investors are backed by other trust-preferred securities issued by the trust subsidiaries.

If a financial institution is financially unsound and defaults on interest payments to the trust, the trust will not be able to make dividend payments to holders of the trust-preferred securities such as the Fund, as the trust typically has no business operations other than holding the subordinated debt issued by the financial institution(s) and issuing the trust-preferred securities and common stock backed by the subordinated debt.

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with trust- preferred securities include: Credit Risk, Interest Rate Risk, Liquidity Risk and Prepayment and Extension Risk.

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 agencies or instrumentalities established or sponsored by the U.S. Government. U.S. Treasury obligations and securities issued or guaranteed by various agencies or instrumentalities 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 Types of 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.

Government-sponsored entities issuing securities include privately owned, publicly chartered entities created to reduce borrowing costs for certain sectors of the economy, such as farmers, homeowners, and students. They include the Federal Farm Credit Bank System, Farm Credit Financial Assistance Corporation, Federal Home Loan Bank, Federal Home Loan Mortgage Corporation (FHLMC), Federal National Mortgage Association (FNMA), Student Loan Marketing Association (SLMA), and Resolution Trust Corporation (RTC). Government-sponsored entities may issue discount notes (with maturities ranging from overnight to 360 days) and bonds. On Sept. 7, 2008, the Federal Housing Finance Agency (FHFA), an agency of the U.S. Government, placed the FHLMC and FNMA into conservatorship, a statutory process with the objective of returning the entities to normal business operations. FHFA will act as the conservator to operate the enterprises until they are stabilized.

Given that there is a limited track record for securities guaranteed under the TLGP, it is uncertain whether such securities will continue to trade in line with recent experience 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 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.

On August 5, 2011, S&P lowered its long-term sovereign credit rating for the United States of America to “AA+” from “AAA”. Because a Fund may invest in U.S. Government obligations, the value of a Fund’s shares may be adversely affected by S&P’s downgrade or any future downgrades of the U.S. Government’s credit rating. While the long-term impact of the downgrade is uncertain, it could, for example, lead to increased volatility in the short-term. See Appendix A for a description of securities ratings.

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with U.S. Government and related obligations include: Credit Risk, Inflation Risk, Interest Rate Risk, Prepayment and Extension Risk, Reinvestment Risk and U.S. Government Obligations Risk.

Variable- and Floating-Rate Obligations

Variable- and floating-rate obligations are debt instruments that 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. Variable- or floating-rate securities frequently include a demand feature enabling the holder to sell the securities to the issuer at par. In many cases, the demand feature can be exercised at any time. Some securities that do not have variable or floating interest rates may be accompanied by puts producing similar results and price characteristics. Variable-rate demand notes include master demand notes that are obligations that permit the investor to invest fluctuating amounts, which may change daily without penalty, pursuant to direct arrangements between the investor (as lender), and the borrower. The interest rates on these notes fluctuate. The issuer of such obligations normally has a corresponding right, after a given period, to prepay in its discretion the outstanding principal amount of the obligations plus accrued interest upon a specified number of days’ notice to the holders of such obligations. Because these obligations are direct lending arrangements between the lender and borrower, it is not contemplated that such instruments generally will be traded. There generally is not an established secondary market for these obligations. Accordingly, where these obligations are not secured by letters of credit or other credit support arrangements, the lender’s right to redeem is dependent on the ability of the borrower to pay principal and interest on demand. Such obligations frequently are not rated by credit rating agencies and may involve heightened risk of

default by the issuer. 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.

Most floating rate loans are acquired directly from the agent bank or from another holder of the loan by assignment. Most such loans are secured, and most impose restrictive covenants on the borrower. These loans are typically made by a syndicate of banks and institutional investors, represented by an agent bank which has negotiated and structured the loan and which is responsible generally for collecting interest, principal, and other amounts from the borrower on its own behalf and on behalf of the other lending institutions in the syndicate, and for enforcing its rights and the rights of the syndicate against the borrower. Each of the lending institutions, including the agent bank, lends to the borrower a portion of the total amount of the loan, and retains the corresponding interest in the loan. Floating rate loans may include delayed draw term loans and prefunded or synthetic letters of credit.

A Fund’s ability to receive payments of principal and interest and other amounts in connection with loans held by it will depend primarily on the financial condition of the borrower. The failure by the Fund to receive scheduled interest or principal payments on a loan would adversely affect the income of the Fund and would likely reduce the value of its assets, which would be reflected in a reduction in the Fund’s net asset value. Banks and other lending institutions generally perform a credit analysis of the borrower before originating a loan or purchasing an assignment in a loan. In selecting the loans in which the Fund will invest, however, the Investment Manager will not rely on that credit analysis of the agent bank, but will perform its own investment analysis of the borrowers. The Investment Manager’s analysis may include consideration of the borrower’s financial strength and managerial experience, debt coverage, additional borrowing requirements or debt maturity schedules, changing financial conditions, and responsiveness to changes in business conditions and interest rates. Investments in loans may be of any quality, including “distressed” loans, and will be subject to the Fund’s credit quality policy.

Loans may be structured in different forms, including assignments and participations. In an assignment, a Fund purchases an assignment of a portion of a lender’s interest in a loan. In this case, the Fund may be required generally to rely upon the assigning bank to demand payment and enforce its rights against the borrower, but would otherwise be entitled to all of such bank’s rights in the loan.

The borrower of a loan may, either at its own election or pursuant to terms of the loan documentation, prepay amounts of the loan from time to time. There is no assurance that a Fund will be able to reinvest the proceeds of any loan prepayment at the same interest rate or on the same terms as those of the original loan.

Corporate loans in which a Fund may purchase a loan assignment are made generally to finance internal growth, mergers, acquisitions, recapitalizations, stock repurchases, leveraged buy-outs, dividend payments to sponsors and other corporate activities. The highly leveraged capital structure of certain borrowers may make such loans especially vulnerable to adverse changes in economic or market conditions. The Fund may hold investments in loans for a very short period of time when opportunities to resell the investments that a Fund’s Portfolio Manager believes are attractive arise.

Certain of the loans acquired by a Fund may involve revolving credit facilities under which a borrower may from time to time borrow and repay amounts up to the maximum amount of the facility. In such cases, the Fund would have an obligation to advance its portion of such additional borrowings upon the terms specified in the loan assignment. To the extent that the Fund is committed to make additional loans under such an assignment, it will at all times designate cash or securities in an amount sufficient to meet such commitments.

Notwithstanding its intention in certain situations to not receive material, non-public information with respect to its management of investments in floating rate loans, the Investment Manager may from time to time come into possession of material, non-public information about the issuers of loans that may be held in a Fund’s portfolio. Possession of such information may in some instances occur despite the Investment Manager’s efforts to avoid such possession, but in other instances the Investment Manager may choose to receive such information (for example, in connection with participation in a creditors’ committee with respect to a financially distressed issuer). As, and to the extent, required by applicable law, the Investment Manager’s ability to trade in these loans for the account of the Fund could potentially be limited by its possession of such information. Such limitations on the Investment Manager’s ability to trade could have an adverse effect on the Fund by, for example, preventing the Fund from selling a loan that is experiencing a material decline in value. In some instances, these trading restrictions could continue in effect for a substantial period of time.

In some instances, other accounts managed by the Investment Manager may hold other securities issued by borrowers whose floating rate loans may be held in a Fund’s portfolio. These other securities may include, for example, debt securities that are subordinate to the floating rate loans held in the Fund’s portfolio, convertible debt or common or preferred equity securities.

Table of Contents

In certain circumstances, such as if the credit quality of the issuer deteriorates, the interests of holders of these other securities may conflict with the interests of the holders of the issuer’s floating rate loans. In such cases, the Investment Manager may owe conflicting fiduciary duties to the Fund and other client accounts. The Investment Manager will endeavor to carry out its obligations to all of its clients to the fullest extent possible, recognizing that in some cases certain clients may achieve a lower economic return, as a result of these conflicting client interests, than if the Investment Manager’s client accounts collectively held only a single category of the issuer’s securities.

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with variable- or floating-rate obligations include: Counterparty Risk, Credit Risk, Interest Rate Risk, Liquidity Risk and Prepayment and Extension Risk.

Warrants and Rights

Warrants and rights are types of securities that give a holder a right to purchase shares of common stock. Warrants usually are issued together with a bond or preferred stock and entitle a holder to purchase a specified amount of common stock at a specified price typically for a period of years. Rights usually have a specified purchase price that is lower than the current market price and entitle a holder to purchase a specified amount of common stock typically for a period of only weeks. Warrants may be used to enhance the marketability of a bond or preferred stock. Warrants do not carry with them the right to dividends or voting rights and they do not represent any rights in the assets of the issuer. Warrants may be considered to have more speculative characteristics than certain other types of investments. In addition, the value of a warrant does not necessarily change with the value of the underlying securities, and a warrant ceases to have value if it is not exercised prior to its expiration date, if any.

The potential exercise price of warrants or rights may exceed their market price, such as when there is no movement in the market price or the market price of the common stock declines.

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with warrants and rights include: Convertible Securities Risk, Credit Risk, Issuer Risk and Market Risk.

When-Issued, Delayed Delivery and Forward Commitment Transactions

When-issued, delayed delivery and forward commitment transactions involve the purchase or sale of securities by a Fund, with payment and delivery taking place in the future after the customary settlement period for that type of security. Normally, the settlement date occurs within 45 days of the purchase although in some cases settlement may take longer. The investor does not pay for the securities or receive dividends or interest on them until the contractual settlement date. When engaging in when-issued, delayed delivery and forward commitment transactions, a 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 a Fund agrees to purchase the securities. A Fund generally will enter into when-issued, delayed delivery and forward commitment transactions only with the intention of completing such transactions. However, a Fund’s portfolio manager may determine not to complete a transaction if it deems it appropriate. In such cases, a Fund may realize short-term gains or losses.

To Be Announced Securities (“TBAs”) . As with other delayed delivery transactions, a seller agrees to issue a TBA security at a future date. However, the seller does not specify the particular securities to be delivered. Instead, the Fund agrees to accept any security that meets specified terms. For example, in a TBA mortgage-backed security transaction, the Fund and the seller would agree upon the issuer, interest rate and terms of the underlying mortgages. The seller would not identify the specific underlying mortgages until it issues the security. TBA mortgage-backed securities increase market risks because the underlying mortgages may be less favorable than anticipated by the Fund. See Types of Investments-Mortgage-Backed Securities and - Asset-Backed Securities

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with when-issued, delayed delivery and forward commitment transactions include: Counterparty Risk, Credit Risk and Market Risk.

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

- 44 -

Table of Contents

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 or STRIPS. 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 that gradually increases over time. 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.

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.

See Appendix A for a discussion of securities ratings.

Although one or more of the other risks described in this SAI may also apply, the risks typically associated with zero-coupon, step-coupon, and pay-in-kind securities include: Credit Risk, Interest Rate Risk and Zero-Coupon Bonds Risk.

Information Regarding Risks

The following is a summary of risk characteristics associated with the various investment instruments available to the Funds for investment. A fund’s risk profile is largely defined by the fund’s primary portfolio holdings and principal investment strategies. However, most funds are allowed to use certain other strategies and investments that may have different risk characteristics. Accordingly, one or more of the following types of risk may be associated with a Fund at any time (for a description of principal risks and investment strategies for an individual fund, please see that Fund’s prospectus):

Active Management Risk. The Fund is actively managed and its performance therefore will reflect, in part, the ability of the portfolio managers to select investments and to make investment decisions that are suited to achieving the Fund’s investment objective. Due to its active management, the Fund could underperform its benchmark index or other funds with similar investment objectives and/or strategies. The Fund may fail to achieve its investment objective(s) and you may lose money.

Allocation Risk.  The Fund uses an asset allocation strategy in pursuit of its investment objective. There is a risk that the Fund’s allocation among asset classes, investments, managers, strategies and/or investment styles will cause the Fund’s shares to lose value or cause the Fund to underperform other funds with similar investment objectives and/or strategies, or that the investments themselves will not produce the returns expected.

Asia Pacific Region Risk. A number of countries in the Asia Pacific region (as described in the Fund’s prospectus) are considered underdeveloped or developing, including from a political, economic and/or social perspective, and may have relatively unstable governments and economies based on limited business, industries and/or natural resources or commodities. Events in any one country within the region may impact that country, other countries in the region or the region as a whole. As a result, events in the region will generally have a greater effect on the Fund than if the Fund were more geographically diversified in areas with more developed countries and economies. This could result in increased volatility in the value of the Fund’s investments and losses within the Fund. Continued growth of economies and securities markets in the region will require sustained economic and fiscal discipline, as well as continued commitment to governmental and regulatory reforms. Development also may be influenced by international economic conditions, including those in the United States and Japan, and by world demand for goods or natural resources produced in countries in the Asia Pacific region. Securities markets in the region are generally smaller and have a lower trading volume than those in the United States, which may result in the securities of some companies in the region being less liquid than U.S. or other foreign securities. Some currencies, inflation rates or interest rates in the Asia Pacific region are or can be volatile, and

- 45 -

Table of Contents

some countries in the region may restrict the flow of money in and out of the country. The risks described under “Emerging Market Securities Risk” and “Foreign Securities Risk” may be more pronounced due to concentration of the Fund’s investments in the region.

Asset-Backed Securities Risk. The value of the Fund’s asset-backed securities may be affected by, among other things, changes in interest rates, factors concerning the interests in and structure of the issuer or the originator of the receivables, the creditworthiness of the entities that provide any supporting letters of credit, surety bonds or other credit enhancements, or the market’s assessment of the quality of underlying assets. Asset-backed securities represent interests in, or are backed by, pools of receivables such as credit card, auto, student and home equity loans. They may also be backed by securities backed by these types of loans and others, such as mortgage loans. Asset-backed securities can have a fixed or an adjustable rate. Most asset-backed securities are subject to prepayment risk, which is the possibility that the underlying debt may be refinanced or prepaid prior to maturity during periods of declining or low interest rates, causing the Fund to have to reinvest the money received in securities that have lower yields. In addition, the impact of prepayments on the value of asset-backed securities may be difficult to predict and may result in greater volatility. Rising or high interest rates tend to extend the duration of asset-backed securities, resulting in valuations that are volatile and sensitive to changes in interest rates.

Changing Distribution Level Risk. The amount of the distributions paid by the Fund will vary and generally depends on the amount of interest income and/or dividends received by the Fund on the securities it holds. The Fund may not be able to pay distributions or may have to reduce its distribution level if the interest income and/or dividends the Fund receives from its investments decline.

Commodity-Related Investment Risk. The value of commodities investments will generally be affected by overall market movements and factors specific to a particular industry or commodity, which may include demand for the commodity, weather, embargoes, tariffs, and economic health, political, international, regulatory and other developments. Economic and other events (whether real or perceived) can reduce the demand for commodities, which may, in turn, reduce market prices and cause the value of Fund shares to fall. The frequency and magnitude of such changes cannot be predicted. Exposure to commodities and commodities markets may subject the value of the Fund’s investments to greater volatility than other types of investments. No or limited, active trading market may exist for certain commodities investments, which may impair the ability to sell or to realize the full value of such investments in the event of the need to liquidate such investments. In addition, adverse market conditions may impair the liquidity of actively traded commodities investments. Certain types of commodities instruments (such as commodity-linked swaps and commodity-linked structured notes) are subject to the risk that the counterparty to the instrument may not perform or be unable to perform in accordance with the terms of the instrument. A subsidiary of the Fund making commodity-related investments generally will not be subject to U.S. laws (including securities laws) and their protections; however, the Subsidiary is wholly-owned and controlled by the Fund, making it unlikely that the Subsidiary will take action contrary to the interests of the Fund and its shareholders. Further, the Subsidiary will be subject to the laws of a foreign jurisdiction, and can be adversely affected by developments in that jurisdiction.

Concentration Risk. Investments that are concentrated in particular issuers, geographic regions or sectors will make the Fund’s portfolio value more susceptible to the events or conditions impacting the issuers, geographic regions or sectors. Because of the Fund’s concentration, the Fund’s overall value may decline to a greater degree or may fluctuate more than if the Fund held a less concentrated portfolio.

Confidential Information Access Risk. In managing the Fund, the Investment Manager normally will seek to avoid the receipt of material, non-public information (Confidential Information) about the issuers of floating rate loans being considered for acquisition by the Fund, or held in the Fund. In many instances, issuers of floating rate loans offer to furnish Confidential Information to prospective purchasers or holders of the issuer’s floating rate loans to help potential investors assess the value of the loan. The Investment Manager’s decision not to receive Confidential Information from these issuers may disadvantage the Fund as compared to other floating rate loan investors, and may adversely affect the price the Fund pays for the loans it purchases, or the price at which the Fund sells the loans. Further, in situations when holders of floating rate loans are asked, for example, to grant consents, waivers or amendments, the Investment Manager’s ability to assess the desirability of such consents, waivers or amendments may be compromised. For these and other reasons, it is possible that the Investment Manager’s decision under normal circumstances not to receive Confidential Information could adversely affect the Fund’s performance.

Convertible Securities Risk. Convertible securities are subject to the usual risks associated with debt securities, such as interest rate risk (i.e., risk of losses attributable to changes in interest rates) and credit risk (i.e., the risk that the issuer of a fixed-income security may or will default or otherwise become unable, or perceived to be unable or unwilling, to honor a financial obligation, such as making payments when due). Convertible securities also react to changes in the value of the common stock into which they convert, and are thus subject to market risk (i.e., the risk that the market values of securities or other investments that the Fund holds will fall, sometimes rapidly or unpredictably, or fail to rise). Because the value of a convertible security can be influenced by both interest rates and the common stock’s market movements, a convertible

- 46 -

Table of Contents

security generally is not as sensitive to interest rates as a similar debt security, and generally will not vary in value in response to other factors to the same extent as the underlying common stock. In the event of a liquidation of the issuing company, holders of convertible securities would typically be paid before the company’s common stockholders but after holders of any senior debt obligations of the company. The Fund may be forced to convert a convertible security before it otherwise would choose to do so, which may decrease the Fund’s return.

Counterparty Risk. The risk that a counterparty to a financial instrument held by the Fund or by a special purpose or structured vehicle invested in by the Fund may become insolvent or otherwise fail to perform its obligations due to financial difficulties, including making payments to the Fund. The Fund may obtain no or limited recovery in a bankruptcy or other organizational proceedings, and any recovery may be significantly delayed.

Credit Risk. Credit risk applies to most debt securities, but is generally less of a factor for obligations backed by the “full faith and credit” of the U.S. Government. It is the risk that the issuer of a fixed-income security may or will default or otherwise become unable or unwilling, or is perceived to be unable or unwilling, to honor a financial obligation, such as making payments to the Fund when due. Various factors could affect the issuer’s actual or perceived willingness or ability to make timely interest or principal payments, including changes in the issuer’s financial condition or in general economic conditions. Debt securities backed by an issuer’s taxing authority may be subject to legal limits on the issuer’s power to increase taxes or otherwise to raise revenue, or may be dependent on legislative appropriation or government aid. Certain debt securities are backed only by revenues derived from a particular project or source, rather than by an issuer’s taxing authority, and thus may have a greater risk of default. If the Fund purchases unrated securities, or if the rating of a security is lowered after purchase, the Fund will depend on analysis of credit risk more heavily than usual. Lower quality or unrated securities held by the Fund present greater credit risk as compared to higher-rated securities.

Depositary Receipts Risks. Depositary receipts are receipts issued by a bank or trust company and evidence of ownership of underlying securities issued by foreign companies. Some foreign securities are traded in the form of American Depositary Receipts (ADRs). Depositary receipts involve the risks of other investments in foreign securities, including risks associated with investing in the particular country, including the political, regulatory, economic, social and other conditions or events occurring in the country, as well as fluctuations in its currency. In addition, ADR holders may not have all the legal rights of shareholders and may experience difficulty in receiving shareholder communications.

Derivatives Risk. A fund may invest in derivatives, including as part of its Principal Investment Strategies (see that section of the prospectus to determine which, if any, derivatives the Fund may utilize as “principal”) and/or its non-principal investment strategies. The Fund may enter into derivative transactions for, among other reasons, investment purposes, for risk management (hedging) purposes, or to increase investment flexibility. The Fund must “set aside” liquid assets, or engage in other appropriate measures to “cover” its obligations under certain derivatives contracts. In the case of certain derivatives contracts that do not cash settle, for example, the Fund must set aside liquid assets equal to the full notional value of the derivatives contract while the positions are open. With respect to other derivatives contracts that do cash settle, however, the Fund is permitted to set aside liquid assets in an amount equal to the Fund’s daily marked-to-market net obligation (i.e., the Fund’s daily net liability) under the contract, if any, rather than the full notional value. The Fund reserves the right to modify its asset segregation policies in the future, including to comply with any changes in positions from time to time articulated by the SEC or its staff regarding asset segregation. By setting aside assets equal to only its net obligations under certain cash-settled derivatives contracts, the Fund will have the ability to employ leverage to a greater extent than if the Fund were required to segregate assets equal to the full notional amount of the contract.

Derivatives Risk/Commodity-Linked Futures Contracts Risk. The use of futures contracts is a highly specialized activity which involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. A futures contract is a sales contract between a buyer (holding the “long” position) and a seller (holding the “short” position) for an asset with delivery deferred until a future date. The buyer agrees to pay a fixed price at the agreed future date and the seller agrees to deliver the asset. The seller hopes that the market price on the delivery date is less than the agreed upon price, while the buyer hopes for the contrary. The liquidity of the futures markets depends on participants entering into off-setting transactions rather than making or taking delivery. To the extent participants decide to make or take delivery, liquidity in the futures market could be reduced. In addition, futures exchanges often impose a maximum permissible price movement on each futures contract for each trading session. The Fund may be disadvantaged if it is prohibited from executing a trade outside the daily permissible price movement. Moreover, to the extent the Fund engages in futures contracts on foreign exchanges, such exchanges may not provide the same protection as U.S. exchanges. The loss that may be incurred in entering into futures contracts may exceed the amount of the premium paid and may be potentially unlimited. Futures markets are highly volatile and the use of futures may increase the volatility of the Fund’s net asset value (NAV). Additionally, as a result of the low collateral deposits normally involved in futures trading, a relatively small price movement in a futures contract may result in substantial losses to the Fund. Investment in these instruments involve risks, including counterparty risk (i.e., the counterparty to the instrument will not perform or be able to perform in accordance with the terms of the instrument), hedging risk (i.e., a hedging strategy may not eliminate the risk that it is intended to offset, and may offset gains, which may lead to losses within the Fund) and pricing risk (i.e., the instrument may be difficult to value).

Derivatives Risk/Commodity-Linked Structured Notes Risk. The use of commodity-linked structured notes is a highly specialized activity which involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The Fund’s investments in commodity-linked structured notes involve substantial risks, including risk of loss of interest and principal, lack of a secondary (i.e. liquid) market, and risk of greater volatility than investments in traditional equity and debt markets.

If payment of interest on a commodity-linked structured note is linked to the value of a particular commodity, commodity index or other economic variable, the Fund might receive lower interest payments (or not receive any of the interest due) on its investments if there is a loss of value of the underlying investment. Further, to the extent that the amount of principal to be repaid upon maturity is linked to the value of a particular commodity, commodity index or other economic variable, the Fund might not receive a portion (or any) of the principal at maturity of the investment or upon earlier exchange. At any time, the risk of loss associated with a particular structured note in the Fund’s portfolio may be significantly higher than the value of the note.

A liquid secondary market may not exist for the commodity-linked structured notes held in the Fund’s portfolio, which may make it difficult for the notes to be sold at a price acceptable to the portfolio managers or to accurately value them. Investment in commodity-linked structured notes also subjects the Fund to counterparty risk (i.e., the counterparty to the instrument will not perform or be able to perform in accordance with the terms of the instrument) and hedging risk (i.e., a hedging strategy may not eliminate the risk that it is intended to offset, and may offset gains, which may lead to losses within the Fund).

The value of the commodity-linked structured notes may fluctuate significantly because the values of the underlying investments to which they are linked are themselves volatile. Additionally, the particular terms of a commodity-linked structured note may create economic leverage by requiring payment by the issuer of an amount that is a multiple of the price increase or decrease of the underlying commodity, commodity index, or other economic variable. Economic leverage will increase the volatility of the value of these commodity-linked notes as they may increase or decrease in value more quickly than the underlying commodity, commodity index or other economic variable.

Derivatives Risk/Commodity-Linked Swaps Risk. The use of commodity-linked swaps is a highly specialized activity which involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. Commodity-linked swaps could result in losses if the underlying asset or reference does not perform as anticipated. The value of swaps, like many other derivatives, may move in unexpected ways and may result in losses for the Fund. Such transactions can have the potential for unlimited losses. Such risk is heightened in the case of short swap transactions. Swaps can involve greater risks than direct investment in the underlying asset, because swaps may be leveraged (creating leverage risk) and are subject to counterparty risk (i.e., the counterparty to the instrument will not perform or be able to perform in accordance with the terms of the instrument), hedging risk (i.e., a hedging strategy may not eliminate the risk that it is intended to offset, and may offset gains, which may lead to losses within the Fund), pricing risk (i.e., swaps may be difficult to value) and liquidity risk (i.e., may not be possible to liquidate a swap position at an advantageous time or price, which may result in significant losses).

Derivatives Risk/Credit Default Swaps Risk. The use of credit default swaps is a highly specialized activity which involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. A credit default swap enables an investor to buy or sell protection against a credit event, such as an issuer’s failure to make timely payments of interest or principal, bankruptcy or restructuring. A credit default swap may be embedded within a structured note or other derivative instrument. The value of swaps, like many other derivatives, may move in unexpected ways and may result in losses for the Fund. Swaps can involve greater risks than direct investment in the underlying securities, because swaps, among other factors, may be leveraged and subject the Fund to counterparty risk (i.e., the counterparty to the instrument will not perform or be unable to perform in accordance with the terms of the instrument), hedging risk (i.e., a hedging strategy may not eliminate the risk that it is intended to offset, and may offset gains, which may lead to losses within the Fund), pricing risk (i.e., swaps may be difficult to value) and liquidity risk (i.e., it may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses). If the Fund is selling credit protection, there is a risk that a credit event will occur and that the Fund will have to pay the counterparty. If the Fund is buying credit protection, there is a risk that no credit event will occur.

Derivatives Risk/Forward Contracts. A forward is a contract between two parties to buy or sell an asset at a specified future time at a price agreed today. Forwards are traded in the over-the-counter markets. The Fund may purchase forward contracts, including those on mortgage-backed securities in the “to be announced” (TBA) market. In the TBA market, the seller agrees to deliver the mortgage backed securities for an agreed upon price on an agreed upon date, but makes no guarantee as to which or how many securities are to be delivered. Investments in forward contracts subject the Fund to counterparty risk.

Derivatives Risk/Forward Foreign Currency Contracts Risk. The use of forward foreign currency contracts is a highly specialized activity which involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. These instruments are a type of derivative contract, whereby the Fund may agree to buy or sell a country’s or region’s currency at a specific price on a specific date, usually 30, 60, or 90 days in the future. These instruments may fall in value due to foreign market downswings or foreign currency value fluctuations. The effectiveness of any currency hedging strategy by a Fund may be reduced by the Fund’s inability to precisely match forward contract amounts and the value of securities involved. Forward foreign currency contracts used for hedging may also limit any potential gain that might result from an increase or decrease in the value of the currency. When entering into forward foreign currency contracts, unanticipated changes in the currency markets could result in reduced performance for the Fund. At or prior to maturity of a forward contract, the Fund may enter into an offsetting contract and may incur a loss to the extent there has been movement in forward contract prices. When the Fund converts its foreign currencies into U.S. dollars, it may incur currency conversion costs due to the spread between the prices at which it may buy and sell various currencies in the market. Investment in these instruments also subjects the Fund, among other factors, to counterparty risk (i.e., the counterparty to the instrument will not perform or be unable to perform in accordance with the terms of the instrument).

Derivatives Risk/Forward Interest Rate Agreements Risk. Under forward interest rate agreements, the buyer locks in an interest rate at a future settlement date. If the interest rate on the settlement date exceeds the lock rate, the buyer pays the seller the difference between the two rates (based on the notional value of the agreement). If the lock rate exceeds the interest rate on the settlement date, the seller pays the buyer the difference between the two rates (based on the notional value of the agreement). The Fund may act as a buyer or a seller. Investment in these instruments subjects the Fund to risks, including counterparty risk (i.e., the counterparty to the instrument will not perform or be able to perform in accordance with the terms of the instrument), hedging risk (i.e., a hedging strategy may not eliminate the risk that it is intended to offset, and may offset gains, which may lead to losses within the Fund) and interest rate risk (i.e., risk of losses attributable to changes in interest rates).

Derivatives Risk/Futures Contracts Risk. The use of futures contracts is a highly specialized activity which involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. A futures contract is a sales contract between a buyer (holding the “long” position) and a seller (holding the “short” position) for an asset with delivery deferred until a future date. The buyer agrees to pay a fixed price at the agreed future date and the seller agrees to deliver the asset. The seller hopes that the market price on the delivery date is less than the agreed upon price, while the buyer hopes for the contrary. The liquidity of the futures markets depends on participants entering into off-setting transactions rather than making or taking delivery. To the extent participants decide to make or take delivery, liquidity in the futures market could be reduced. In addition, futures exchanges often impose a maximum permissible price movement on each futures contract for each trading session. The Fund may be disadvantaged if it is prohibited from executing a trade outside the daily permissible price movement. Moreover, to the extent the Fund engages in futures contracts on foreign exchanges, such exchanges may not provide the same protection as U.S. exchanges. The loss that may be incurred in entering into futures contracts may exceed the amount of the premium paid and may be potentially unlimited. Futures markets are highly volatile and the use of futures may increase the volatility of the Fund’s net asset value (NAV). Additionally, as a result of the low collateral deposits normally involved in futures trading, a relatively small price movement in a futures contract may result in substantial losses to the Fund. Investment in these instruments involve risks, including counterparty risk (i.e., the counterparty to the instrument will not perform or be able to perform in accordance with the terms of the instrument), hedging risk (i.e., a hedging strategy may not eliminate the risk that it is intended to offset, and may offset gains, which may lead to losses within the Fund) and pricing risk (i.e., the instrument may be difficult to value).

Derivatives Risk/Interest Rate Swaps Risk. Interest rate swaps can be based on various measures of interest rates, including LIBOR, swap rates, treasury rates and other foreign interest rates. A swap agreement can increase or decrease the volatility of the Fund’s investments and its net asset value. The value of swaps, like many other derivatives, may move in unexpected ways and may result in losses for the Fund. Swaps can involve greater risks than direct investment in securities, because swaps may be leverage, and are, among other factors, subject to counterparty risk (i.e., the counterparty to the instrument will not perform or be able to perform in accordance with the terms of the instrument), hedging risk (i.e., a hedging strategy may not eliminate the risk that it is intended to offset, and may offset gains, which may lead to losses within the Fund), pricing risk (i.e., swaps may be difficult to value), liquidity risk (i.e., it may not be possible to liquidate a swap position at an advantageous time or price, which may result in significant losses) and interest rate risk (i.e., risk of losses attributable to changes in interest rates).

Derivatives Risk/Inverse Floaters Risk. Inverse floaters (or inverse variable or floating rate securities) are a type of derivative, long-term fixed income obligation with a variable or floating interest rate that moves in the opposite direction of short-term interest rates. As short-term interest rates go down, the holders of the inverse floaters receive more income and, as short-term interest rates go up, the holders of the inverse floaters receive less income. Variable rate securities provide for a specified periodic adjustment in the interest rate, while floating rate securities have interest rates that change whenever there is a change in a designated benchmark rate or the issuer’s credit quality. While inverse floaters tend to provide more

income than similar term and credit quality fixed-rate bonds, they also exhibit greater volatility in price movement. There is a risk that the current interest rate on variable and floating rate securities may not accurately reflect current market interest rates or adequately compensate the holder for the current creditworthiness of the issuer. Some variable or floating rate securities are structured with liquidity features and some may include market-dependent liquidity features that may present greater liquidity risk. Other risks associated with transactions in inverse floaters include interest rate risk (i.e., risk of losses attributable to changes in interest rates), counterparty risk (i.e., the risk that the issuer of a security may or will default or otherwise become unable, or perceived to be unable or unwilling, to honor a financial obligation, such as making payments when due) and hedging risk (i.e., a hedging strategy may not eliminate the risk that it is intended to offset, and may offset gains, which may lead to losses within the Fund).

Derivatives Risk/Options Risk. The use of options is a highly specialized activity which involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The Fund may buy and sell call and put options, including options on currencies, interest rates and swap agreements (commonly referred to as swaptions). If the Fund sells a put option, there is a risk that the Fund may be required to buy the underlying asset at a disadvantageous price. If the Fund sells a call option, there is a risk that the Fund may be required to sell the underlying asset at a disadvantageous price, and if the call option sold is not covered (for example, by owning the underlying asset), the Fund’s losses are potentially unlimited. Options may be traded on a securities exchange or in the over-the-counter markets. These transactions involve other risks, including counterparty risk (i.e., the counterparty to the instrument will not perform or be able to perform in accordance with the terms of the instrument) and hedging risk (i.e., a hedging strategy may not eliminate the risk that it is intended to offset, and may offset gains, which may lead to losses within the Fund).

Derivatives Risk/Portfolio Swaps and Total Return Swaps Risk. The use of portfolio swaps or total return swaps is a highly specialized activity which involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. In a swap transaction, one party agrees to pay the other party an amount equal to the total return of a defined underlying asset (such as an equity security or basket of such securities) or a non-asset reference (such as an index) during a specified period of time. In return, the other party would make periodic payments based on a fixed or variable interest rate or on the total return from a different underlying asset or non-asset reference. Portfolio swaps and equity swaps could result in losses if the underlying asset or reference does not perform as anticipated. The value of swaps, like many other derivatives, may move in unexpected ways and may result in losses for the Fund. Such transactions can have the potential for unlimited losses. Such risk is heightened in the case of short swap transactions. Swaps can involve greater risks than direct investment in the underlying asset, because swaps may be leveraged (creating leverage risk) and are subject to counterparty risk (i.e., the counterparty to the instrument will not perform or be able to perform in accordance with the terms of the instrument), hedging risk (i.e., a hedging strategy may not eliminate the risk that it is intended to offset, and may offset gains, which may lead to losses within the Fund), pricing risk (i.e., swaps may be difficult to value) and liquidity risk (i.e., may not be possible to liquidate a swap position at an advantageous time or price, which may result in significant losses).

Derivatives Risk/Swaps Risk. The use of swaps is a highly specialized activity which involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. In a swap transaction, one party agrees to pay the other party an amount equal to the return, based upon an agreed-upon notional value, of a defined underlying asset or a non-asset reference (such as an index) during a specified period of time. In return, the other party would make periodic payments based on a fixed or variable interest rate or on the return from a different underlying asset or non-asset reference based upon an agreed-upon notional value. Swaps could result in losses if the underlying asset or reference does not perform as anticipated. The value of swaps, like many other derivatives, may move in unexpected ways and may result in losses for the Fund. Such transactions can have the potential for unlimited losses. Such risk is heightened in the case of swap transactions involving short exposures. Swaps can involve greater risks than direct investment in the underlying asset, because swaps may be leveraged (creating leverage risk in that the Fund’s exposure and potential losses are greater than the amount invested) and are subject to counterparty risk (i.e., the counterparty to the instrument will not perform or be able to perform in accordance with the terms of the instrument), hedging risk (i.e., a hedging strategy may not eliminate the risk that it is intended to offset, and may offset gains, which may lead to losses within the Fund), pricing risk (i.e., swaps may be difficult to value) and liquidity risk (i.e., may not be possible to liquidate a swap position at an advantageous time or price, which may result in significant losses).

Derivatives Risk/Total Return Swaps Risk. The use of total return swaps is a highly specialized activity which involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. In a total return swap transaction, one party agrees to pay the other party an amount equal to the total return of a defined underlying asset (such as an equity security or basket of such securities) or a non-asset reference (such as an index) during a specified period of time. In return, the other party makes periodic payments based on a fixed or variable interest rate or on the total return from a different underlying asset or non-asset reference. Total return swaps could result in losses if the underlying asset or reference does not perform as anticipated. Such transactions can have the potential for unlimited losses. The value of swaps, like many other derivatives, may move in unexpected ways and may result in losses for the Fund. Swaps can involve greater risks than direct investment in securities, because swaps may be leveraged, are subject to counterparty risk

(i.e., the counterparty to the instrument will not perform or be able to perform in accordance with the terms of the instrument), hedging risk (i.e., a hedging strategy may not eliminate the risk that it is intended to offset, and may offset gains, which may lead to losses within the Fund), pricing risk (i.e., may be difficult to value) and liquidity risk (i.e., it may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

Derivatives Risk/Warrants Risk. Warrants are securities giving the holder the right, but not the obligation, to buy the stock of an issuer at a given price (generally higher than the value of the stock at the time of issuance) during a specified period or perpetually. Warrants may be acquired separately or in connection with the acquisition of securities. Warrants do not carry with them the right to dividends or voting rights and they do not represent any rights in the assets of the issuer. In addition, the value of a warrant does not necessarily change with the value of the underlying securities, and a warrant ceases to have value if it is not exercised prior to its expiration date. Warrants may be subject to the risk that the securities could lose value. There also is the risk that the potential exercise price may exceed the market price of the warrants or rights. Investment in these instruments also subject the Fund to liquidity risk (i.e., it may not be possible for the Fund to liquidate the instrument at an advantageous time or price, which may result in significant losses to the Fund).

Dividend and Income Risk. The income shareholders receive from the fund is based primarily on dividends and interest it earns from its investments as well as gains the fund receives from selling portfolio securities, each of which can vary widely over the short and long-term. The dividend income from an fund’s investments in equity securities will be influenced by both general economic activity and issuer-specific factors. In the event of a recession or adverse events affecting a specific industry or issuer, the issuers of the equity securities held by an fund’s may reduce the dividends paid on such securities.

Dollar Rolls Risk. Dollar rolls are transactions in which the Fund sells securities to a counterparty and simultaneously agrees to purchase those or similar securities in the future at a predetermined price. 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 counterparty may default on its obligations. These transactions may also increase the Fund’s portfolio turnover rate. If the Fund reinvests the proceeds of the security sold, the Fund will also be subject to the risk that the investments purchased with such proceeds will decline in value (a form of leverage risk).

Emerging Market Securities Risk.  Securities issued by foreign governments or companies in emerging market countries are more likely to have greater exposure to the risks of investing in foreign securities that are described in Foreign Securities Risk. In addition, emerging market countries are more likely to experience instability resulting, for example, from rapid changes or developments in social, political and economic conditions. Their economies are usually less mature and their securities markets are typically less developed with more limited trading activity (i.e., lower trading volumes and less liquidity) than more developed countries. Emerging market securities tend to be more volatile than securities in more developed markets. Many emerging market countries are heavily dependent on international trade and have fewer trading partners, which makes them more sensitive to world commodity prices and economic downturns in other countries. Some emerging market countries have a higher risk of currency devaluations, and some of these countries may experience periods of high inflation or rapid changes in inflation rates and may have hostile relations with other countries.

Energy and Natural Resources Sector Risk.  The Fund is subject to the risk that the securities of the issuers engaged in the energy and natural resources sector will underperform other market sectors or the market as a whole. To the extent that the Fund invests in issuers conducting business in these or similar sectors, the Fund is subject to a greater extent to legislative or regulatory changes, adverse market conditions and/or increased competition affecting that sector or those sectors. The values of natural resources are affected by numerous factors including, among other factors, events occurring in nature and local and international politics. For instance, natural events (such as earthquakes, hurricanes or fires in prime natural resources areas) and political events (such as government instability or military confrontations) can affect the overall supply of a natural resource and thereby the value of companies involved in business activities relating to such natural resource. In addition, rising interest rates and high inflation may affect the demand for certain natural resources and, therefore, the price of related investments. In addition, prices of, and thus the Fund’s investments in, precious metals are considered speculative and are affected by a variety of worldwide and economic, financial and political factors. Prices of precious metals may fluctuate sharply.

Equity-Linked Notes Risk. Investments in ELNs have the potential to lead to significant losses because ELNs are subject to the market and volatility risks associated with their Underlying Equity, and to additional risks not typically associated with investments in listed equity securities, such as liquidity risk, credit risk of the issuer of the ELNs (or its broker-dealer affiliate, collectively referred to in this section as the “issuer”), and concentration risk. In general, an investor in an ELN, such as a Fund, has the same market risk as an investor in the Underlying Equity. The liquidity of an ELN that is not actively traded on an exchange is linked to the liquidity of the Underlying Equity.

- 51 -

Table of Contents

The liquidity of unlisted ELNs is normally determined by the willingness of the issuer to make a market in the ELN. While the Fund will seek to purchase ELNs only from issuers that it believes to be willing to, and capable of, repurchasing the ELN at a reasonable price, there can be no assurance that the Fund will be able to sell any ELN at such a price or at all. This may impair the Fund’s ability to enter into other transactions at a time when doing so might be advantageous.

In addition, because ELNs are often unsecured notes of the issuer, the Fund would be subject to the credit risk of the issuer and the potential risk of being too concentrated in the securities (including ELNs) of that issuer. The Fund bears the risk that the issuer may default on its obligations under the ELN. In the event of insolvency of the issuer, the Fund will be unable to obtain the intended benefits of the ELN. Moreover, it may be difficult to obtain market quotations for purposes of valuing the Fund’s ELNs and computing the Fund’s net asset value.

Price movements of an ELN will likely differ significantly from price movements of the Underlying Equity, resulting in the risk of loss if the Fund’s portfolio managers are incorrect in their expectation of fluctuations in securities prices, interest rates or currency prices or other relevant features of an ELN.

Focused Portfolio Risk. The Fund, because it may invest in a limited number of companies, may have more volatility in its net asset value and is considered to have more risk than a fund that invests in a greater number of companies because changes in the value of a single security may have a more significant effect, either negative or positive, on the Fund’s net asset value. To the extent the Fund invests its assets in fewer securities, the Fund is subject to greater risk of loss if any of those securities decline in price.

Foreign Currency Risk. The performance of the Fund may be materially affected positively or negatively by foreign currency strength or weakness relative to the U.S. dollar, particularly if the Fund invests a significant percentage of its assets in foreign securities or other assets denominated in currencies other than the U.S. dollar. Currency rates in foreign countries may fluctuate significantly over short periods of time for a number of reasons, including changes in interest rates, imposition of currency controls and economic or political developments in the U.S. or abroad. The Fund may also incur currency conversion costs when converting foreign currencies into U.S. dollars.

Foreign Securities Risk. Foreign securities are subject to special risks as compared to securities of U.S. issuers. For example, foreign markets can be extremely volatile. Foreign securities are primarily denominated in foreign currencies. Fluctuations in currency exchange rates may impact the value of foreign securities, without a change in the intrinsic value of those securities. Foreign securities may also be less liquid than domestic securities so that the Fund may, at times, be unable to sell foreign securities at desirable times or prices. Brokerage commissions, custodial costs and other fees are also generally higher for foreign securities. The Fund may have limited or no legal recourse in the event of default with respect to certain foreign securities, including those issued by foreign governments. In addition, foreign governments may impose withholding or other taxes on the Fund’s income and capital gain on foreign securities, which could reduce the Fund’s yield on such securities. Other risks include possible delays in the settlement of transactions or in the payment of income; generally less publicly available information about companies; the impact of economic, political, social, diplomatic or other conditions or events; possible seizure, expropriation or nationalization of a company or its assets; possible imposition of currency exchange controls; accounting, auditing and financial reporting standards that may be less comprehensive and stringent than those applicable to domestic companies; and local agents are held only to the standard of care of the local markets, which may be less reliable than the U.S. markets. It may be difficult to obtain reliable information about the securities and business operations of certain foreign issuers. Governments or trade groups may compel local agents to hold securities in designated depositories that are not subject to independent evaluation. The less developed a country’s securities market is, the greater the level of risks.

Frequent Trading Risk.  The portfolio managers may actively and frequently trade investments in the Fund’s portfolio to carry out its investment strategies. A change in the securities held by a fund is known as “portfolio turnover.” Frequent trading of investments increases the possibility that the Fund, as relevant, will realize taxable capital gains (including short-term capital gains, which are generally taxable to shareholders at higher rates than long-term capital gains for U.S. federal income tax purposes), which could reduce the Fund’s after-tax return. Frequent trading can also mean higher brokerage and other transaction costs, which could reduce the Fund’s return. The trading costs and tax effects associated with portfolio turnover may adversely affect the Fund’s performance.

Frontier Market Risk. Frontier market countries generally have smaller economies and even less developed capital markets than typical emerging market countries (which themselves have increased investment risk relative to investing in more developed markets) and, as a result, the risks of investing in emerging market countries are magnified in frontier market countries. The increased risks include the potential for extreme price volatility and illiquidity in frontier market countries; government ownership or control of parts of private sector and of certain companies; trade barriers, exchange controls, managed adjustments in relative currency values and other protectionist measures imposed or negotiated by the countries with which frontier market countries trade; and the relatively new and unsettled securities laws in many frontier market countries. Securities issued by foreign governments or companies in frontier market countries are even more likely

- 52 -

Table of Contents

than emerging markets securities to have greater exposure to the risks of investing in foreign securities that are described in Foreign Securities Risk. In addition, frontier market countries are more likely to experience instability resulting, for example, from rapid changes or developments in social, political and economic conditions. Many frontier market countries are heavily dependent on international trade, which makes them more sensitive to world commodity prices and economic downturns and other conditions in other countries. Some frontier market countries have a higher risk of currency devaluations, and some of these countries may experience periods of high inflation or rapid changes in inflation rates and may have hostile relations with other countries.

Geographic Concentration Risk. The Fund may be particularly susceptible to economic, political, regulatory or other events or conditions affecting issuers and countries within the specific geographic regions in which the Fund invests. Currency devaluations could occur in countries that have not yet experienced currency devaluation to date, or could continue to occur in countries that have already experienced such devaluations. As a result, the Fund’s net asset value may be more volatile than a more geographically diversified fund.

For State-specific Funds. Because the Fund invests substantially in municipal securities issued by the state identified in the Fund’s name and political sub-divisions of that state, the Fund will be particularly affected by adverse tax, legislative, regulatory, demographic or political changes as well as changes impacting the state’s financial, economic or other condition and prospects. This vulnerability to factors affecting the Fund’s tax-exempt investments will be significantly greater than that of a more geographically diversified fund, which may result in greater losses and volatility. In addition, because of the relatively small number of issuers of tax-exempt securities in the state, the Fund may invest a higher percentage of assets in a single issuer and, therefore, be more exposed to the risk of loss than a fund that invests more broadly. The value of municipal securities owned by the Fund also may be adversely affected by future changes in federal or state income tax laws. See the SAI for details.

Geographic Concentration Risk/Europe Risk. Because the Fund concentrates its investments in Europe, the Fund may be particularly susceptible to economic, political, regulatory or other events or conditions affecting issuers and countries in Europe. Most developed countries in Western Europe are members of the European Union (EU), and many are also members of the European Economic and Monetary Union (EMU). European countries can be significantly affected by the tight fiscal and monetary controls that the EMU imposes on its members and with which candidates for EMU membership are required to comply. In addition, the private and public sectors’ debt problems of a single EU country can pose significant economic risks to the EU as a whole. Unemployment in Europe has historically been higher than in the United States and public deficits are an ongoing concern in many European countries. Currency devaluations could occur in countries that have not yet experienced currency devaluation to date, or could continue to occur in countries that have already experienced such devaluations. As a result, the Fund’s net asset value may be more volatile than a more geographically diversified fund. If securities of issuers in Europe fall out of favor, it may cause the Fund to underperform other funds that do not concentrate in this region of the world.

Gold ETF and Mining Securities Risk. Shares of exchange-traded funds related to gold or other precious or special minerals (Gold ETFs) generally represent units of fractional undivided beneficial interests in a trust. The shares are intended to reflect the performance of the price of gold bullion. Because a Gold ETF has operating expenses and transaction and other costs (including storage and insurance costs) while the price of gold bullion does not, a Gold ETF will sell gold from time to time to pay expenses. This will reduce the amount of gold represented by each Gold ETF share, irrespective of whether the trading price of the shares rises or falls in response to changes in the price of gold. An investment in a Gold ETF is subject to all of the risks of investing directly in gold bullion and mining securities. In addition, the market value of the shares of the Gold ETF may differ from their net asset value because the supply and demand in the market for shares of the Gold ETF at any point in time is not always identical to the supply and demand in the market for the underlying assets. Under certain circumstances, a Gold ETF could be terminated. Should termination occur, the Gold ETF might have to liquidate its holding at a time when the price of gold may not be advantageous to the Fund. The Fund may invest directly in, or indirectly through the Subsidiary or by means of derivative instruments, securities issued by companies that are involved in mining or processing or dealing in gold or other metals or minerals. These securities are described as “Mining Securities.” Investments in Mining Securities and Gold ETFs involve additional risks and considerations not typically associated with other types of investments: (1) the risk of substantial price fluctuations of gold and precious metals; (2) the concentration of gold supply is mainly in five locations (South Africa, Australia, the Commonwealth of Independent States (the former Soviet Union), Canada and the United States), and the prevailing economic and political conditions of these countries may have a direct effect on the production and marketing of gold and sales of central bank gold holdings; (3) unpredictable international monetary policies, economic and political conditions; and (4) possible U.S. Governmental regulation of gold and precious metals, as well as foreign regulation of such investments.

Greater China Regional Risk. The Greater China region consists of Hong Kong, The People’s Republic of China and Taiwan, among other countries, and the Fund’s investments in the region are particularly susceptible to risks in that region. Adverse events in any one country within the region may impact the other countries in the region or Asia as a whole. As a result, adverse events in the region will generally have a greater effect on the Fund than if the Fund were more geographically diversified, which could result in greater volatility in the Fund’s net asset value and losses. Markets in the Greater China region can experience significant volatility due to social, economic, regulatory and political uncertainties.

Growth Securities Risk. Growth securities typically trade at a higher multiple of earnings than other types of equity securities. Accordingly, the market values of growth securities may be more sensitive to adverse economic or other circumstances or changes in current or expected earnings than the market values of other types of securities. In addition, growth securities, at times, may not perform as well as value securities or the stock market in general, and may be out of favor with investors for varying periods of time.

Health Care Sector Risk. Companies in the health care sector are subject to extensive government regulation. Their profitability can be affected significantly and adversely by restrictions on government reimbursement for medical expenses, government approval of medical products and services, competitive pricing pressures, an increased emphasis on outpatient and other alternative services and other factors. In many cases, patent protection is integral to the success of companies in the health care sector, and profitability can be affected materially by, among other things, the cost of obtaining (or failing to obtain) patent approvals, the cost of litigating patent infringement and the loss of patent protection for medical products (which significantly increases pricing pressures and can materially reduce profitability with respect to such products). Companies in the health care sector also potentially are subject to extensive product liability and other similar litigation. Companies in the health care sector are affected by the rising cost of medical products and services, and the effects of such rising costs can be particularly pronounced for companies that are dependent on a relatively limited number of products or services. Medical products also frequently become obsolete due to industry innovation or other causes. Because the Fund invests a significant portion of its net assets in the equity securities of health care companies, the Fund’s price may be more volatile than a fund that is invested in a more diverse range of companies in different market sectors.

Highly Leveraged Transactions Risk. The loans or other securities in which the Fund invests may consist of transactions involving refinancings, recapitalizations, mergers and acquisitions and other financings for general corporate purposes. The Fund’s investments also may include senior obligations of a borrower issued in connection with a restructuring pursuant to Chapter 11 of the U.S. Bankruptcy Code (commonly known as “debtor-in-possession” financings), provided that such senior obligations are determined by the Fund’s portfolio managers to be a suitable investment for the Fund. In such highly leveraged transactions, the borrower assumes large amounts of debt in order to have the financial resources to attempt to achieve its business objectives. Such business objectives may include but are not limited to: management’s taking over control of a company (leveraged buy-out); reorganizing the assets and liabilities of a company (leveraged recapitalization); or acquiring another company. Loans or securities that are part of highly leveraged transactions involve a greater risk (including default and bankruptcy) than other investments.

Impairment of Collateral Risk. The value of collateral, if any, securing a loan can decline, and may be insufficient to meet the borrower’s obligations or difficult or costly to liquidate. In addition, the Fund’s access to collateral may be limited by bankruptcy or other insolvency laws. Further, certain floating rate and other loans may not be fully collateralized and may decline in value.

Index Risk.  The Fund’s value will generally decline when the performance of its targeted index declines. In addition, because the Fund may not hold all issues included in its index, it may not always be fully invested. The Fund also bears advisory, administrative and other expenses and transaction costs in trading securities, which the index does not bear. Accordingly, the Fund’s performance will likely fail to match the performance of its targeted index, after taking expenses into account. It is not possible to invest directly in an index.

Industry Concentration Risk.  Investments that are concentrated in a particular industry will make the Fund’s portfolio value more susceptible to the events or conditions impacting that particular industry.

Inflation-Protected Securities Risk. Inflation-protected debt securities tend to react to changes in real interest rates. Real interest rates can be described as nominal interest rates minus the expected impact of inflation. In general, the price of an inflation-protected debt security falls when real interest rates rise, and rises when real interest rates fall. Interest payments on inflation-protected debt securities will vary as the principal and/or interest is adjusted for inflation and may be more volatile than interest paid on ordinary bonds. In periods of deflation, the Fund may have no income at all from such investments. Income earned by a shareholder depends on the amount of principal invested, and that principal will not grow with inflation unless the shareholder reinvests the portion of Fund distributions that comes from inflation adjustments. The Fund’s investment in certain inflation-protected debt securities may generate taxable income in excess of the interest they pay to the Fund, which may cause the Fund to sell investments to obtain cash to make income distributions to shareholders, including at times when it may not be advantageous to do so.

Infrastructure-Related Companies Risk. Because the Fund concentrates its investments in infrastructure-related securities, the Fund has greater exposure to adverse economic, regulatory, political, legal, and other conditions or events, affecting the issuers of such securities. Infrastructure-related businesses are subject to a variety of factors that may adversely affect their business or operations including high interest costs in connection with capital construction programs,

- 54 -

Table of Contents

costs associated with environmental and other regulations, the effects of an economic slowdown and surplus capacity, increased competition, uncertainties concerning availability of fuel at reasonable prices, the effects of energy conservation policies and other factors. Additionally, infrastructure-related entities may be subject to regulation by various governmental authorities and may also be affected by governmental regulation of rates charged to customers, service interruption and/or legal challenges due to environmental, operational or other conditions or events and the imposition of special tariffs and changes in tax laws, regulatory policies and accounting standards. There is also the risk that corruption may negatively affect publicly-funded infrastructure projects, especially in foreign markets, resulting in work stoppage, delays and cost overruns.

Initial Public Offering (IPO) Risk. IPOs are subject to many of the same risks as investing in companies with smaller market capitalizations. To the extent the Fund determines to invest in IPOs, it may not be able to invest to the extent desired, because, for example, only a small portion (if any) of the securities being offered in an IPO are available to the Fund. The investment performance of the Fund during periods when it is unable to invest significantly or at all in IPOs may be lower than during periods when the Fund is able to do so. In addition, as the Fund increases in size, the impact of IPOs on the Fund’s performance will generally decrease. IPOs sold within 12 months of purchase may result in increased short-term capital gains, which will be taxable to the Fund’s shareholders as ordinary income.

Interest Rate Risk. Interest rate risk is the risk of losses attributable to changes in interest rates. In general, if prevailing interest rates rise, the values of debt securities will tend to fall, and if interest rates fall, the values of debt securities will tend to rise. Changes in the value of a debt security usually will not affect the amount of income the Fund receives from it but may affect the value of the Fund’s shares. In general, the longer the maturity or duration of a debt security, the greater its sensitivity to changes in interest rates. Interest rate declines also may increase prepayments of debt obligations, which, in turn, would increase prepayment risk. As interest rates rise or spreads widen, the likelihood of prepayment decreases.

Investing in Other Funds Risk. The Fund’s investment in other funds (affiliated and/or unaffiliated funds, including exchange-traded funds (ETFs)) subjects the Fund to the investment performance (positive or negative) and risks of these underlying funds in direct proportion to the Fund’s investment therein. The performance of underlying funds could be adversely affected if other entities that invest in the same underlying funds make relatively large investments or redemptions in such underlying funds. The Fund, and its shareholders, indirectly bear a portion of the expenses of any funds in which the Fund invests. Because the expenses and costs of a fund are shared by its investors, redemptions by other investors in the fund could result in decreased economies of scale and increased operating expenses for such fund. These transactions might also result in higher brokerage, tax or other costs for the Fund. This risk may be particularly important when one investor owns a substantial portion of another fund. The Investment Manager (or subadviser, as the case may be) may have potential conflicts of interest in selecting affiliated underlying funds for investment by the Fund because the fees paid to it by some underlying funds are higher than the fees paid by other underlying funds, as well as a potential conflict in selecting affiliated funds over unaffiliated funds.

Investing in Wholly Owned Subsidiary Risk. By investing in one or more wholly owned subsidiaries organized under the laws of the Cayman Islands (Subsidiary), the Fund is indirectly exposed to the risks associated with the Subsidiary’s investments. The Subsidiary is subject to the same Principal Risk that the Fund is subject to (which are described in that Fund’s prospectus). There can be no assurance that the investment objective of the Subsidiary will be achieved. The Subsidiary is not registered under the 1940 Act and, except as otherwise noted in the Fund’s prospectus, is not subject to the investor protections of the 1940 Act. However, the Fund wholly owns and controls the Subsidiary, and the Fund and the Subsidiary are both managed by Columbia Management and subadvised by the Fund’s subadviser(s), making it unlikely that the Subsidiary will take action contrary to the interests of the Fund and its shareholders. The Fund’s Board of Trustees has oversight responsibility for the investment activities of the Fund, including its investment in the Subsidiary, and the Fund’s role as sole shareholder of the Subsidiary. In managing the Subsidiary’s investment portfolio, Columbia Management will manage the Subsidiary’s portfolio in accordance with the Fund’s investment policies and restrictions. Changes in the laws of the United States and/or the Cayman Islands, under which the Fund and the Subsidiary, respectively, are organized, could result in the inability of the Fund and/or the Subsidiary to operate as described in the Fund’s prospectus and this SAI and could adversely affect the Fund and its shareholders. For example, the Cayman Islands currently does not impose any income, corporate or capital gains tax, estate duty, inheritance tax, gift tax or withholding tax on the Subsidiary. If Cayman Islands law were changed and the Subsidiary was required to pay Cayman Island taxes, the investment returns of the Fund would likely decrease.

Issuer Risk. An issuer in which the Fund invests may perform poorly, and therefore, the value of its securities may decline, which would negatively affect the Fund’s performance. Poor performance may be caused by poor management decisions, competitive pressures, breakthroughs in technology, reliance on suppliers, labor problems or shortages, corporate restructurings, fraudulent disclosures, natural disasters or other events, conditions or factors.

Leverage Risk. Leverage occurs when the Fund increases its assets available for investment using borrowings, short sales, derivatives, or similar instruments or techniques. The use of leverage may make any change in the Fund’s net asset value (NAV) even greater and thus result in increased volatility of returns. Short sales involve borrowing securities and then

- 55 -

Table of Contents

selling them, the Fund’s short sales effectively leverage the Fund’s assets. The Fund’s assets that are used as collateral to secure the Fund’s obligations to return the securities sold short may decrease in value while the short positions are outstanding, which may force the Fund to use its other assets to increase the collateral. Leverage can create an interest expense that may lower the Fund’s overall returns. Leverage presents the opportunity for increased net income and capital gains, but also exaggerates the Fund’s risk of loss. There can be no guarantee that a leveraging strategy will be successful.

Liquidity Risk.

General. Liquidity risk is the risk associated with a lack of marketability of investments which may make it difficult to sell the investment at a desirable time or price. The Fund may have to lower the selling price, sell other investments, or forego another, more appealing investment opportunity. Judgment plays a larger role in valuing these investments as compared to valuing more liquid investments.

Municipal Securities. At times, market conditions could result in reduced liquidity for certain securities held by the Fund. The municipal securities market is an over-the-counter market, which means that the Fund purchases and sells investments through municipal bond dealers. The Fund’s ability to sell securities held in its portfolio is dependent on the willingness and ability of market participants to provide bids that reflect current market prices. Adverse market conditions could result in a lack of liquidity by reducing the number of ready buyers. Lower-rated securities may be less liquid than higher-rated securities. Certain derivative instruments in which the Fund may invest may also be subject to reduced liquidity, particularly under certain market conditions. Reduced liquidity may make it difficult or impossible to sell the security at a desirable time or price. The Fund may have to lower the selling price of its investment, sell other investments, or forego another, more appealing investment opportunity. Judgment plays a larger role in valuing these investments as compared to valuing more liquid investments.

Low and Below Investment Grade (High-Yield) Securities Risk. Securities with the lowest investment grade rating and securities rated below investment grade (commonly called “high-yield” or “junk” bonds) and unrated securities of comparable quality tend to be more sensitive to credit risk than higher-rated securities and may react more to perceived changes in the ability of the issuing entity or obligor to pay interest and principal when due than to changes in interest rates. These investments have greater price fluctuations and are more likely to experience a default than higher-rated securities. High-yield securities are considered to be predominantly speculative with respect to the issuer’s capacity to pay interest and repay principal. These securities typically pay a premium – a higher interest rate or yield – because of the increased risk of loss, including default. These securities may require a greater degree of judgment to establish a price, may be difficult to sell at the time and price the Fund desires, may carry high transaction costs, and also are generally less liquid than higher-rated securities. The securities ratings provided by third party rating agencies are based on analyses by these ratings agencies of the credit quality of the securities and may not take into account every risk related to whether interest or principal will be timely repaid. In adverse economic and other circumstances, issuers of lower-rated securities are more likely to have difficulty making principal and interest payments than issuers of higher-rated securities.

Market Risk. Market risk refers to the possibility that the market values of securities or other investments that the Fund holds will fall, sometimes rapidly or unpredictably, or fail to rise. Security values may fall or fail to rise because of a variety of factors affecting (or the market’s perception of) individual companies (e.g., an unfavorable earnings report), industries or sectors, or the markets as a whole, reducing the value of an investment in the Fund. Accordingly, an investment in the Fund could lose money over short or even long periods. The market values of the securities the Fund holds also can be affected by changes or perceived changes in U.S. or foreign economies and financial markets, and the liquidity of these securities, among other factors. In general, equity securities tend to have greater price volatility than debt securities. In addition, common stock prices may be sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase.

Master Limited Partnership Risk. Investments in securities (units) of master limited partnerships involve risks that differ from an investment in common stock. Holders of these units have more limited rights to vote on matters affecting the partnership. These units may be subject to cash flow and dilution risks. There are also certain tax risks associated with such an investment. In particular, the Fund’s investment in master limited partnerships can be limited by the Fund’s intention to qualify as a regulated investment company for U.S. federal income tax purposes, and can limit the Fund’s ability to so qualify. In addition, conflicts of interest may exist between common unit holders, subordinated unit holders and the general partner of a master limited partnership, including a conflict arising as a result of incentive distribution payments. In addition, there are risks related to the general partner’s right to require unit holders to sell their common units at an undesirable time or price.

Mid-Cap Company Risk. Securities of mid-capitalization companies (mid-cap companies) can, in certain circumstances, have more risk than securities of larger capitalization companies (larger companies). For example, mid-cap companies may be more vulnerable to market downturns and adverse business or economic events than larger companies because they may have more limited financial resources and business operations. Mid-cap companies are also more likely than larger companies to have more limited product lines and operating histories and to depend on smaller management teams. Securities of mid-cap companies may trade less frequently and in smaller volumes and may be less liquid and fluctuate more sharply in value than securities of larger companies. When the Fund takes significant positions in mid-cap companies

with limited trading volumes, the liquidation of those positions, particularly in a distressed market, could be difficult and result in Fund investment losses. In addition, some mid-cap companies may not be widely followed by the investment community, which can lower the demand for their stocks.

Money Market Fund Investment Risk. An investment in a money market fund is not a bank deposit and is not insured or guaranteed by any bank, the FDIC or any other government agency. Although money market funds seek to preserve the value of investments at $1.00 per share, it is possible for the Fund to lose money by investing in money market funds. In addition to the fees and expenses that the Fund directly bears, the Fund indirectly bears the fees and expenses of any money market funds in which it invests, including affiliated money market funds. To the extent these fees and expenses are expected to equal or exceed 0.01% of the Fund’s average daily net assets, they will be reflected in the Annual Fund Operating Expenses set forth in the table under “Fees and Expenses of the Fund.” By investing in a money market fund, the Fund will be exposed to the investment risks of the money market fund in direct proportion to such investment. The money market fund may not achieve its investment objective. The Fund, through its investment in the money market fund, may not achieve its investment objective. To the extent the Fund invests in instruments such as derivatives, the Fund may hold investments, which may be significant, in money market fund shares to cover its obligations resulting from the Fund’s investments in derivatives.

Mortgage- and Other Asset-Backed Securities Risk.  The value of the Fund’s mortgage-backed and other asset-backed securities may be affected by, among other things, changes or perceived changes in: interest rates, factors concerning the interests in and structure of the issuer or the originator of the mortgages or other assets, the creditworthiness of the entities that provide any supporting letters of credit, surety bonds or other credit enhancements, or the market’s assessment of the quality of underlying assets. Mortgage-backed securities represent interests in, or are backed by, pools of mortgages from which payments of interest and principal (net of fees paid to the issuer or guarantor of the securities) are distributed to the holders of the mortgage-backed securities. Mortgage-backed securities can have a fixed or an adjustable rate. Payment of principal and interest on some mortgage-backed securities (but not the market value of the securities themselves) may be guaranteed (i) by the full faith and credit of the U.S. Government (in the case of securities guaranteed by the Government National Mortgage Association) or (ii) by its agencies, authorities, enterprises or instrumentalities (in the case of securities guaranteed by the Federal National Mortgage Association (FNMA) or the Federal Home Loan Mortgage Corporation (FHLMC)), which are not insured or guaranteed by the U.S. Government (although FNMA and FHLMC may be able to access capital from the U.S. Treasury to meet their obligations under such securities). Mortgage-backed securities issued by non-governmental issuers (such as commercial banks, savings and loan institutions, private mortgage insurance companies, mortgage bankers and other secondary market issuers) may be supported by various credit enhancements, such as pool insurance, guarantees issued by governmental entities, letters of credit from a bank or senior/subordinated structures, and may entail greater risk than obligations guaranteed by the U.S. Government, whether or not such obligations are guaranteed by the private issuer. Mortgage-backed securities are subject to prepayment risk, which is the possibility that the underlying mortgage may be refinanced or prepaid prior to maturity during periods of declining or low interest rates, causing the Fund to have to reinvest the money received in securities that have lower yields. In addition, the impact of prepayments on the value of mortgage-backed securities may be difficult to predict and may result in greater volatility. Rising or high interest rates tend to extend the duration of mortgage-backed securities, making them more volatile and more sensitive to changes in interest rates.

Multi-Adviser Risk. Where a Fund has multiple subadvisers (as the case may be), each subadviser makes investment decisions independently from the other subadviser(s). It is possible that the security selection process of one subadviser will not complement or may conflict or even contradict that of the other subadviser(s), including makings off-setting trades that have no net effect to the Fund, but which may increase Fund expenses. As a result, the Fund’s exposure to a given security, industry, sector or market capitalization could be smaller or larger than if the Fund were managed by a single subadviser, which could affect the Fund’s performance.

Municipal Securities Risk.  Municipal securities are debt obligations generally issued to obtain funds for various public purposes, including general financing for state and local governments, or financing for a specific project or public facility. Municipal securities can be significantly affected by political and legislative changes at the state or federal level. Municipal securities may be fully or partially backed by the taxing authority of the local government, by the credit of a private issuer, by the current or anticipated revenues from a specific project or specific assets or by domestic or foreign entities providing credit support, such as letters of credit, guarantees or insurance, and are generally classified into general obligation bonds and special revenue obligations. General obligation bonds are backed by an issuer’s taxing authority and may be vulnerable to limits on a government’s power or ability to raise revenue or increase taxes. They may also depend for payment on legislative appropriation and/or funding or other support from other governmental bodies. Revenue obligations are payable from revenues generated by a particular project or other revenue source, and are typically subject to greater risk of default than general obligation bonds because investors can look only to the revenue generated by the project or other revenue source backing the project, rather than to the general taxing authority of the state or local government issuer of the obligations. Because many municipal securities are issued to finance projects in sectors such as education, health care, transportation and utilities, conditions in those sectors can affect the overall municipal market. Municipal securities

generally pay interest that, in the opinion of bond counsel, is free from U.S. federal income tax (and, in some cases, the federal alternative minimum tax). There is no assurance that the Internal Revenue Service (IRS) will agree with this opinion. In the event the IRS determines that the issuer does not comply with relevant tax requirements, interest payments from a security could become federally taxable, possibly retroactively to the date the security was issued, and the value of the security would likely fall. As a shareholder of the Fund, you may be required to file an amended tax return and pay additional taxes as a result. The amount of publicly available information for municipal issuers is generally less than for corporate issuers.

Municipal Securities Risk/Health Care Sector Risk. The Fund’s investments in municipal securities may include securities of issuers in the health care sector, which subjects the Fund’s investments to the risks associated with that sector, including the risk of regulatory action or policy changes by numerous governmental agencies and bodies, including federal, state, and local governmental agencies, as well as requirements imposed by private entities, such as insurance companies. A major source of revenue for the health care industry is payments from the Medicare and Medicaid programs. As a result, the industry is sensitive to legislative changes and reductions in governmental spending for such programs. Numerous other factors may affect the industry, such as general and local economic conditions, demand for services, expenses (including, among others, malpractice insurance premiums) and competition among health care providers. Additional factors also may adversely affect health care facility operations, such as adoption of legislation proposing a national health insurance program, other state or local health care reform measures, medical and technological advances that alter the need for or cost of health services or the way in which such services are delivered, changes in medical coverage that alter the traditional fee-for-service revenue stream, and efforts by employers, insurers, and governmental agencies to reduce the costs of health insurance and health care services.

Non-Diversified Fund Risk.  A Fund that is non-diversified may invest a greater percentage of its total assets in the securities of fewer issuers than a “diversified” fund. This increases the risk that a change in the value of any one investment held by the Fund could affect the overall value of the Fund more than it would affect that of a diversified fund holding a greater number of investments. Accordingly, the Fund’s value will likely be more volatile than the value of a more diversified fund.

Preferred Stock Risk. Preferred stock is a type of stock that pays dividends at a specified rate and that has preference over common stock in the payment of dividends and the liquidation of assets. Preferred stock does not ordinarily carry voting rights. The price of a preferred stock is generally determined by earnings, type of products or services, projected growth rates, experience of management, liquidity, and general market conditions of the markets on which the stock trades. The most significant risks associated with investments in preferred stock include Issuer Risk and Market Risk.

Prepayment and Extension Risk. Prepayment and extension risk is the risk that a loan, bond or other security or investment might be called or otherwise converted, prepaid or redeemed before maturity. This risk is primarily associated with asset-backed securities, including mortgage-backed securities and floating rate loans. If the investment is converted, prepaid or redeemed before maturity, particularly during a time of declining interest rates or spreads, the portfolio managers may not be able to invest the proceeds in other investments providing as high a level of income, resulting in a reduced yield to the Fund. Conversely, as interest rates rise or spreads widen, the likelihood of prepayment decreases and the maturity of the investment may extend. The portfolio managers may be unable to capitalize on securities with higher interest rates or wider spreads because the Fund’s investments are locked in at a lower rate for a longer period of time.

Quantitative Model Risk. For Funds that use quantitative methods to select investments, securities or other investments selected using quantitative methods may perform differently from the market as a whole or from their expected performance for many reasons, including factors used in building the quantitative analytical framework, the weights placed on each factor, and changing sources of market returns, among others. Any errors or imperfections in the Fund portfolio manager’s quantitative analyses or models, or in the data on which they are based, could adversely affect the ability of the Investment Manager or a sub-adviser to use such analyses or models effectively, which in turn could adversely affect the Fund’s performance. There can be no assurance that these methodologies will help the Fund to achieve its objective.

Real Estate-related Investment Risk. Investment in real estate investment trusts (REITs) and in securities of other companies (wherever organized) principally engaged in the real estate industry subjects the Fund, among other risks, risks similar to those of direct investments in real estate and the real estate industry in general, including risks related to general and local economic conditions, possible lack of availability of financing and changes in interest rates or property values. REITs are entities that either own properties or make construction or mortgage loans, and also may include operating or finance companies. The value of REIT shares is affected by, among other factors, changes in the value of the underlying properties owned by the REIT, by changes in the prospect for earnings and/or cash flow growth of the REIT itself, defaults by borrowers or tenants, market saturation, decreases in market rates for rents, and other economic, political, or regulatory matters affecting the real estate industry, including REITs. REITs and similar non-U.S. entities depend upon specialized management skills, may have limited financial resources, may have less trading volume in their securities, and may be subject to more abrupt or erratic price movements than the overall securities markets. REITs are also subject to the risk of

failing to qualify for tax-free pass-through of income. Some REITs (especially mortgage REITs) are affected by risks similar to those associated with investments in debt securities including changes in interest rates and the quality of credit extended. Because the value of REITs and other real estate-related companies may [fluctuate widely in response to changes in factors affecting the real estate markets, the value of an investment in the Fund may be more volatile than the value of an investment in a fund that is invested in a more diverse range of market sectors.

Redemption Risk. The fund may need to sell portfolio securities to meet redemption requests. The fund could experience a loss when selling portfolio securities to meet redemption requests if there is (i) significant redemption activity by shareholders, including, for example, when a single investor or few large investors make a significant redemption of fund shares, (ii) a disruption in the normal operation of the markets in which the fund buys and sells portfolio securities or (iii) the inability of the fund to sell portfolio securities because such securities are illiquid. In such events, the fund could be forced to sell portfolio securities at unfavorable prices in an effort to generate sufficient cash to pay redeeming shareholders. The fund may suspend redemptions or the payment of redemption proceeds when permitted by applicable regulations.

Regulatory Risk. Changes in government regulations may adversely affect the value of a security held by the Fund. In addition, the SEC has adopted amendments to money market regulation, imposing liquidity, credit quality, and maturity requirements on all money market funds. These changes may result in reduced yields for money market funds, including the Fund. The SEC or the Congress may adopt additional changes to money market regulation, which may impact the operation or performance of the Fund.

Reinvestment Risk.  Reinvestment risk is the risk that the Fund will not be able to reinvest income or principal at the same return it is currently earning.

Repurchase Agreements Risk. Repurchase agreements are agreements in which the seller of a security to the Fund agrees to repurchase that security from the Fund at a mutually agreed upon price and time. Repurchase agreements carry the risk that the counterparty may not fulfill its obligations under the agreement. This could cause the Fund’s income and the value of your investment in the Fund to decline.

Reverse Repurchase Agreements Risk. Reverse repurchase agreements are agreements in which a Fund sells a security to a counterparty, such as a bank or broker-dealer, in return for cash and agrees to repurchase that security at a mutually agreed upon price and time. Reverse repurchase agreements carry the risk that the market value of the security sold by the Fund may decline below the price at which the Fund must repurchase the security. Reverse repurchase agreements also may be viewed as a form of borrowing.

Rule 144A Securities Risk.  The Fund may invest significantly in privately placed securities that have not been registered for sale under the Securities Act of 1933 pursuant to Rule 144A (Rule 144A securities) that are determined to be liquid in accordance with procedures adopted by the Fund’s Board. However, an insufficient number of qualified institutional buyers interested in purchasing Rule 144A securities at a particular time could affect adversely the marketability of such securities and the Fund might be unable to dispose of such securities promptly or at reasonable prices. Accordingly, even if determined to be liquid, the Fund’s holdings of Rule 144A securities may increase the level of Fund illiquidity if eligible buyers become uninterested in buying them at a particular time. The Fund may also have to bear the expense of registering the securities for resale and the risk of substantial delays in effecting the registration. Additionally, the purchase price and subsequent valuation of restricted and illiquid securities normally reflect a discount, which may be significant, from the market price of comparable securities for which a liquid market exists.

Secondary Market Trading Risk. Investors buying or selling shares in the secondary market will pay brokerage commissions or other charges imposed by brokers as determined by that broker. Brokerage commissions are often a fixed amount and may be a significant proportional cost for investors seeking to buy or sell relatively small amounts of shares. In addition, secondary market investors will also incur the cost of the difference between the price that an investor is willing to pay for shares (the bid price) and the price at which an investor is willing to sell shares (the ask price). This difference in bid and ask prices is often referred to as the “spread” or “bid/ask spread.” The bid/ask spread varies over time for shares based on trading volume and market liquidity, and is generally lower if the Fund’s shares have more trading volume and market liquidity and higher if the Fund’s shares have little trading volume and market liquidity. Further, increased market volatility may cause increased bid/ask spreads.

Sector Risk. At times, the Fund may have a significant portion of its assets invested in securities of companies conducting business in a related group of industries within an economic sector. Companies in the same economic sector may be similarly affected by economic, regulatory, political or market events or conditions, making the Fund more vulnerable to unfavorable developments in that economic sector than funds that invest more broadly. The more a fund diversifies its investments, the more it spreads risk and potentially reduces the risks of loss and volatility.

Short Positions Risk. The Fund may establish short positions which introduce more risk to the Fund than long positions (where the Fund owns the instrument) because the maximum sustainable loss on an instrument purchased (held long) is limited to the amount paid for the instrument plus the transaction costs, whereas there is no maximum price of the shorted instrument when purchased in the open market. Therefore, in theory, short positions have unlimited risk. The Fund’s use of short positions in effect “leverages” the Fund. Leverage potentially exposes the Fund to greater risks of loss due to unanticipated market movements, which may magnify losses and increase the volatility of returns. To the extent the Fund takes a short position in a derivative instrument, this involves the risk of a potentially unlimited increase in the value of the underlying instrument.

Small- and Mid-Cap Company Securities Risk. Securities of small- and mid-capitalization companies (small- and mid-cap companies) can, in certain circumstances, have a higher potential for gains than securities of larger companies but may also have more risk. For example, small- and mid-cap companies may be more vulnerable to market downturns and adverse business or economic events than larger, more established companies (larger companies) because they may have more limited financial resources and business operations. Small- and mid-cap companies are also more likely than larger companies to have more limited product lines and operating histories and to depend on smaller management teams. Securities of small- and mid-cap companies may trade less frequently and in smaller volumes and may be less liquid and fluctuate more sharply in value than securities of larger companies. In cases where the Fund takes significant positions in small- and mid-cap companies with limited trading volumes, the liquidation of those positions, particularly in a distressed market, could be prolonged and result in investment losses. In addition, some small- and mid-cap companies may not be widely followed by the investment community, which can lower the demand for their stocks.

Small Company Securities Risk. Securities of small-capitalization companies (small-cap companies) can, in certain circumstances, have a higher potential for gains than securities of larger-capitalization companies (larger companies) but may also have more risk. For example, small-cap companies may be more vulnerable to market downturns and adverse business or economic events than larger companies because they may have more limited financial resources and business operations. Small-cap companies are also more likely than larger companies to have more limited product lines and operating histories and to depend on smaller management teams. Securities of small-cap companies may trade less frequently and in smaller volumes and may be less liquid and fluctuate more sharply in value than securities of larger companies. When the Fund takes significant positions in small-cap companies with limited trading volumes, the liquidation of those positions, particularly in a distressed market, could be prolonged and result in Fund investment losses. In addition, some small-cap companies may not be widely followed by the investment community, which can lower the demand for their stocks.

Sovereign Debt Risk. A sovereign debtor’s willingness or ability to repay principal and pay interest in a timely manner may be affected by a variety of factors, including its cash flow situation, the extent of its reserves, the availability of sufficient foreign exchange on the date a payment is due, the relative size of the debt service burden to the economy as a whole, the sovereign debtor’s policy toward international lenders, and the political constraints to which a sovereign debtor may be subject.

With respect to sovereign debt of emerging market issuers, investors should be aware that certain emerging market countries are among the largest debtors to commercial banks and foreign governments. At times, certain emerging market countries have declared moratoria on the payment of principal and interest on external debt. Certain emerging market countries have experienced difficulty in servicing their sovereign debt on a timely basis and that has led to defaults and the restructuring of certain indebtedness to the detriment of debt holders. Sovereign debt risk is increased for emerging market issuers.

Special Situations Risk. Securities of companies that are involved in an initial public offering or a major corporate event, such as a business consolidation or restructuring, may present special risk because of the high degree of uncertainty that can be associated with such events. Securities issued in initial public offerings often are issued by companies that are in the early stages of development, have a history of little or no revenues and may operate at a loss following the offering. It is possible that there will be no active trading market for the securities after the offering, and that the market price of the securities may be subject to significant and unpredictable fluctuations. Investing in special situations may have a magnified effect on the performance of funds with small amounts of assets.

State-Specific Municipal Securities Risk. Securities issued by a particular state and its instrumentalities are subject to the risk of unfavorable developments in such state. Because the Fund may invest without limit in municipal securities of issuers in any state, the value of Fund shares may be more volatile than the value of shares of funds that limit their investments in municipal securities of issuers in any one state, as unfavorable developments have the potential to impact more significantly the Fund than funds that limit their investments in municipal securities of any one state. A municipal security can be significantly affected by adverse tax, legislative, regulatory, demographic or political changes as well as changes in the state’s financial, economic or other condition and prospects. The SAI provides greater detail about risks specific to the municipal securities in which the Fund invests, which investors should carefully consider.

Stripped Securities Risk. Stripped securities are the separate income or principal components of debt securities. These securities are particularly sensitive to changes in interest rates, and therefore subject to greater fluctuations in price than typical interest bearing debt securities. For example, stripped mortgage-backed securities have greater interest rate risk than mortgage-backed securities with like maturities, and stripped treasury securities have greater interest rate risk than traditional government securities with identical credit ratings.

Tax Risk related to Forward Foreign Currency Contracts. As a regulated investment company (RIC), the Fund must derive at least 90% of its gross income for each taxable year from sources treated as “qualifying income” under the Internal Revenue Code of 1986, as amended. The Fund may gain exposure to local currency markets through forward currency contracts. Although foreign currency gains currently constitute “qualifying income,” the Treasury Department has the authority to issue regulations excluding from the definition of “qualifying income” a RIC’s foreign currency gains not “directly related” to its “principal business” of investing in stock or securities (or options and futures with respect thereto). Such regulations might treat gains from some of the Fund’s foreign currency-denominated positions as not qualifying income and there is a remote possibility that such regulations might be applied retroactively, in which case, the Fund might not qualify as a RIC for one or more years. In the event the Treasury Department issues such regulations, the Fund’s Board of Trustees may authorize a significant change in investment strategy or the Fund’s liquidation.

Tax Risk related to Commodities Investments. As a regulated investment company, the Fund must derive at least 90% of its gross income for each taxable year from sources treated as “qualifying income” under the Internal Revenue Code of 1986, as amended. The Fund generally intends to gain exposure to the commodities markets through investments that give rise to qualifying income, by investing directly in commodity-linked instruments that the Fund believes give rise to qualifying income, or indirectly through its investments in the Subsidiary, which, in turn, would invest in commodities or commodity-linked instruments. The Subsidiary intends to operate in such a manner that the 90% gross income requirement in respect of the Fund is satisfied. The Fund must also meet certain asset diversification requirements in order to qualify as a regulated investment company, including investing no more than 25% of its total assets in the Subsidiary as of the end of each quarter of its taxable year. If the Fund does not appropriately limit its commodity-linked investments, including its investments in the Subsidiary, or if such investments are re-characterized for U.S. federal income tax purposes, the Fund may be unable to qualify as a regulated investment company for one or more years, which would adversely affect the value of the Fund and the favorable tax treatment of Contracts funded by the Fund. In this event, the Fund’s Board of Trustees may authorize a significant change in investment strategy or the Fund’s liquidation.

Technology and Technology-Related Investment Risk. Companies in the technology sector and technology-related sectors are subject to significant competitive pressures, such as aggressive pricing of their products or services, new market entrants, competition for market share, short product cycles due to an accelerated rate of technological developments and the potential for limited earnings and/or falling profit margins. These companies also face the risks that new services, equipment or technologies will not be accepted by consumers and businesses or will become rapidly obsolete. These factors can affect the profitability of these companies and, as a result, the value of their securities. Also, patent protection is integral to the success of many companies in these sectors, and profitability can be affected materially by, among other things, the cost of obtaining (or failing to obtain) patent approvals, the cost of litigating patent infringement and the loss of patent protection for products (which significantly increases pricing pressures and can materially reduce profitability with respect to such products). In addition, many technology companies have limited operating histories. Prices of these companies’ securities historically have been more volatile than other securities, especially over the short term. Because the Fund invests a significant portion of its net assets in the equity securities of technology companies, the Fund’s price may be more volatile than a fund that is invested in a more diverse range of market sectors.

Trading Discount to NAV Risk. The Fund’s shares may trade above or below their NAV. The NAV of the Fund will generally fluctuate with changes in the market value of the Fund’s holdings. The market prices of shares, however, will generally fluctuate in accordance with changes in NAV as well as the relative supply of, and demand for, shares on the Exchange. The trading price of shares may deviate significantly from NAV. The Investment Manager cannot predict whether shares will trade below, at or above their NAV. Price differences may be due, in large part, to the fact that supply and demand forces at work in the secondary trading market for shares will be closely related to, but not identical to, the same forces influencing the prices of the securities held by the Fund. However, given that shares can be purchased and redeemed in large blocks of shares, called Creation Units (defined below) (unlike shares of closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their NAV), and the Fund’s portfolio holdings are fully disclosed on a daily basis, the Investment Manager believes that large discounts or premiums to the NAV of shares should not be sustained, but that may not be the case.

Trading Risk. Although the Shares are listed on the Exchange, there can be no assurance that an active or liquid trading market for them will develop or be maintained. In addition, trading in Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable. Further, trading in Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

U.S. Government Obligations Risk. While U.S. Treasury obligations are backed by the “full faith and credit” of the U.S. Government, such securities are nonetheless subject to credit risk (i.e., the risk that the U.S. Government may be, or may be perceived to be, unable or unwilling to honor its financial obligations, such as making payments). Securities issued or guaranteed by federal agencies or authorities and U.S. Government-sponsored instrumentalities or enterprises may or may not be backed by the full faith and credit of the U.S. Government. For example, securities issued by the Federal Home Loan Mortgage Corporation, the Federal National Mortgage Association and the Federal Home Loan Banks are neither insured nor guaranteed by 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, authority, instrumentality or enterprise and, as a result, are subject to greater credit risk than securities issued or guaranteed by the U.S. Treasury. Securities guaranteed by the Federal Deposit Insurance Corporation under its Temporary Liquidity Guarantee Program (TLGP) are subject to certain risks, including whether such securities will continue to trade in line with recent experience in relation to treasury and government agency securities in terms of yield spread and the volatility of such spread, as well as uncertainty as to how such securities will trade in the secondary market and whether that market will be liquid or illiquid. The TLGP is subject to change. See the SAI for additional information about investments in U.S. Government and related obligations.

Value Securities Risk. Value securities are securities of companies that may have experienced, for example, adverse business, industry or other developments or may be subject to special risks that have caused the securities to be out of favor and, in turn, potentially undervalued. The market value of a portfolio security may not meet the Fund portfolio manager’s perceived value assessment of that security, or may decline in price, even though the Fund portfolio manager(s) believe the securities are already undervalued. There is also a risk that it may take longer than expected for the value of these investments to rise to the portfolio manager’s perceived value. In addition, value securities, at times, may not perform as well as growth securities or the stock market in general, and may be out of favor with investors for varying periods of time.

Zero-Coupon Bonds Risk. Zero-coupon bonds are bonds that do not pay interest in cash on a current basis, but instead accrue interest over the life of the bond. As a result, these securities are issued at a discount and their values may fluctuate more than the values of similar securities that pay interest periodically. Although these securities pay no interest to holders prior to maturity, interest accrued on these securities is reported as income to the Fund and affects the amounts distributed to its shareholders, which may cause the Fund to sell investments to obtain cash to make income distributions to shareholders, including at times when it may not be advantageous to do so.

Borrowings

Each Fund has a fundamental policy with respect to borrowing that can be found under the heading About the Funds’ Investments – Fundamental and Non-Fundamental Investment Policies . Specifically, each 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 Funds. In general, pursuant to the 1940 Act, a 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 Funds participate in a committed line of credit (Line of Credit). Any advance under the Line of Credit is contemplated primarily for temporary or emergency purposes.]

Lending Of Portfolio Securities

Certain Funds may make secured loans of their portfolio securities, however, securities loans will not be made if, as a result, the aggregate amount of all outstanding securities loans by a Fund exceeds 33 1/3% of its total assets (including the market value of collateral received). For purposes of complying with a Fund’s investment policies and restrictions, collateral received in connection with securities loans is deemed an asset of the Fund to the extent required by law. A Fund continues to receive dividends or interest, as applicable, on the securities loaned and simultaneously earns either interest on the investment of the cash collateral or fee income if the loan is otherwise collateralized.

To the extent a Fund engages in securities lending, securities loans will be made to broker-dealers that the Investment Manager believes to be of relatively high credit standing pursuant to agreements requiring that the loans continuously be collateralized by cash, liquid securities, or shares of other investment companies with a value at least equal to the market value of the loaned securities. As with other extensions of credit, the Fund bears the risk of delay in the recovery of the securities and of loss of rights in the collateral should the borrower fail financially. The Fund also bears the risk that the value of investments made with collateral may decline.

Voting rights or rights to consent with respect to the loaned securities pass to the borrower. A Fund has the right to call loans at any time on reasonable notice. However, the Fund bears the risk of delay in the return of the security, impairing the Fund’s ability to vote on such matters. The Investment Manager will retain lending agents on behalf of the Funds that are compensated based on a percentage of the Fund’s return on its securities lending. A Fund may also pay various fees in connection with securities loans, including shipping fees and custodian fees.
