MORE ABOUT THE PORTFOLIO’S INVESTMENTS AND RISKS

The Risk/Return Summary describes the Portfolio’s investment objective and its principal investment strategies and risks. This section provides some additional information about the Portfolio’s investments and certain portfolio management techniques that the Portfolio may use. More information about the Portfolio’s investments and portfolio management techniques, some of which entail risks, is included in the SAI.

More About the Portfolio’s Investments

Mortgage-Related Securities. Mortgage-related securities may be issued by private companies or by government-sponsored entities or agencies of the U.S. government, such as the Government National Mortgage Association (“Ginnie Mae”), Federal National Mortgage Association (“Fannie Mae”), Federal Home Loan Mortgage Corporation (“Freddie Mac”) and Federal Home Loan Banks. Mortgage-related securities represent direct or indirect participations in, or are collateralized by and payable from, mortgage loans secured by real property. Ginnie Mae is a wholly-owned corporation of the U.S. government.

Mortgage-related securities may include multiple class securities, including collateralized mortgage obligations (“CMOs”) and Real Estate Mortgage Investment Conduit (“REMIC”) pass-through or participation certificates. CMOs provide an investor with a specified interest in the cash flow from a pool of underlying mortgages or of other mortgage-related securities. A REMIC is a CMO that qualifies for special tax treatment under the Internal Revenue Code of 1986, as amended, and invests in certain mortgages principally secured by interests in real property and other permitted investments. CMOs may exhibit more or less price volatility and interest rate sensitivity than other types of mortgage-related obligations, and under certain interest rate and payment scenarios, the Portfolio may fail to recoup fully its investment in certain of these securities regardless of their credit quality.

Stripped mortgage-backed securities (“SMBS”) represent the right to receive payments of interest (“IOs”) or payments of principal (“POs”) on underlying pools of mortgage securities, but not both. The value of these types of instruments may change more drastically than debt securities that pay both principal and interest during periods of changing interest rates. IOs are particularly subject to prepayment risk. The Portfolio may obtain a below market yield or incur a loss on such instruments. POs are particularly subject to extension risk.

Mortgage instruments, such as SMBS, often employ features that have the effect of leverage. As a result, small changes in interest rates may cause large and sudden price movements, especially compared to an investment in a security that is not leveraged.

The Portfolio seeks to invest in floating rate debt instruments (“floaters”). While floaters provide a certain degree of protection against rises in interest rates, their yields fall in a decline in interest rates as well. The Portfolio may also invest in inverse floating rate debt instruments (“inverse floaters”). An inverse floater may exhibit greater price volatility than a fixed rate obligation of similar credit quality. The Portfolio may also invest in inverse floating IOs, which are IO securities related to inverse floaters. The Portfolio generally may invest no more than 50% of its total assets at the time of purchase in IO, inverse floating interest only, or PO securities in the aggregate. Within this 50% limit, IO, inverse floating IO and PO securities each will generally be no more than 20% of the Portfolio’s total assets at the time of purchase.

Mortgage Dollar Rolls. The Portfolio may enter into mortgage dollar rolls to finance the purchase of additional investments. Dollar rolls expose the Portfolio to the risk that it will lose money if the additional investments do not produce enough income to cover the Portfolio’s dollar roll obligations. In addition, if the Adviser’s prepayment assumptions are incorrect, the Portfolio may have performed better had the Portfolio not entered into the mortgage dollar roll.

U.S. Government Securities. U.S. government securities include U.S. Treasury obligations and obligations issued or guaranteed by U.S. government agencies, instrumentalities or sponsored enterprises. U.S. Treasury obligations include, among other things, the separately traded principal and interest components of securities guaranteed or issued by the U.S. Treasury that are traded independently under the Separate Trading of Registered Interest and Principal of Securities program (“STRIPS”).

U.S. government securities have historically involved little risk of loss of principal if held to maturity. However, no assurance can be given that the U.S. government will provide financial support to U.S. government agencies, authorities, instrumentalities or sponsored enterprises if it is not obligated to do so by law.

Custodial Receipts. Interests in U.S. government securities may be purchased in the form of custodial receipts that evidence ownership of future interest payments, principal payments or both on certain notes or bonds issued or guaranteed as to principal and interest by the U.S. government, its agencies, instrumentalities or authorities. For certain securities law purposes, custodial receipts are not considered obligations of the U.S. government.

Leverage. The Portfolio’s investments in mortgage-related securities may involve the use of leverage. The Portfolio may make margin purchases of securities and, in connection with the purchases, borrow money from banks and other financial institutions for investment purposes. The Portfolio may also engage in selling securities short, which is a form of leverage. Although the use of leverage by the Portfolio may create an opportunity for increased return, it also results in additional risks and can magnify the effect of any losses. There is no assurance that the use of leverage as an investment strategy will be successful.

Repurchase Agreements. Repurchase agreements involve the purchase of securities subject to the seller’s agreement to repurchase them at a mutually agreed upon date and price. The Portfolio may enter into repurchase agreements with securities dealers and banks that furnish collateral at least equal in value or market price to the amount of their repurchase obligation. Repurchase agreements are considered to be loans by the Portfolio under the Investment Company Act of 1940, as amended (the “1940 Act”).

If the other party or “seller” defaults, the Portfolio might suffer a loss to the extent that the proceeds from the sale of the underlying securities and other collateral held by the Portfolio are less than the repurchase price and the Portfolio’s cost associated with delay and enforcement of the repurchase agreement. In addition, in the event of bankruptcy of the seller, the Portfolio could suffer additional losses if a court determines that the Portfolio’s interest in the collateral is not enforceable.

Borrowings and Reverse Repurchase Agreements. The Portfolio can borrow money from banks and other financial institutions, and the Portfolio may enter into reverse repurchase agreements as permitted by law for leverage provided there is asset coverage of at least 300% of the amount borrowed, or for temporary or emergency purposes. Reverse repurchase agreements involve the sale of securities held by the Portfolio subject to the Portfolio’s agreement to repurchase them at a mutually agreed upon date and price (including interest). These transactions may be entered into as a temporary measure for emergency purposes or to meet redemption requests. The Portfolio may also enter into reverse repurchase agreements when the Adviser believes that the interest income to be earned from the investment of the transaction proceeds will be greater than the related interest expense. Borrowings and reverse repurchase agreements involve leverage. If the securities held by the Portfolio decline in value while these transactions are outstanding, the net asset value of the Portfolio’s outstanding shares will decline in value by proportionately more than the decline in value of the securities. In addition, reverse repurchase agreements involve the risks that the investment return earned by the Portfolio (from the investment of the proceeds) will be less than the interest expense of the transaction, that the market value of the securities sold by the Portfolio will decline below the price the Portfolio is obligated to pay to repurchase the securities, and that the securities may not be returned to the Portfolio.

Other Investment Companies. The Portfolio may invest in securities of other investment companies subject to the limitations contained in the 1940 Act. The Portfolio will indirectly bear its proportionate share of any management fees and other expenses paid by such other investment companies. Such other investment companies will have investment objectives, policies and/or restrictions that fall within the criteria set forth in the FCUA, subject to the waiver granted by the NCUA with respect to its rules and regulations.

Inverse Floaters. The Portfolio may invest in inverse floating rate debt securities (“inverse floaters”). The interest rate on inverse floaters resets in the opposite direction from the market rate of interest to which the inverse floater is indexed. An inverse floater may be considered to be leveraged to the extent that its interest rate varies by a magnitude that exceeds the magnitude of the change in the index rate of interest. The higher the degree of leverage of an inverse floater, the greater the volatility of its market value. Inverse floaters may present a greater degree of market risk than many types of securities, and may be more volatile, less liquid and more difficult to price accurately than less complex securities.

Bank Obligations. The Portfolio may invest in U.S. dollar-denominated obligations issued or guaranteed by U.S. banks with total assets exceeding $1 billion (including obligations issued by foreign branches of such banks) but only to the extent permitted under the FCUA and the rules and regulations thereunder. Bank obligations may include certificates of deposit, bankers’ acceptances, bank notes, deposit notes, and other obligations. Bank obligations may be general obligations of the parent bank or may be limited to the issuing branch by the terms of the specific obligations or by government regulation.

Futures Contracts and Options on Futures Contracts. The Portfolio may purchase and sell Federal Funds, Treasury and Eurodollar futures contracts and may purchase and write put and call options on such futures contracts. Futures contracts are standardized, exchange-traded contracts that provide for the sale or purchase of a specified financial instrument at a future time at a specified price. An option on a futures contract gives the purchaser the right (and the writer of the option the obligation) to assume a position in a futures contract at a specified exercise price within a specified period of time. A futures contract may be based on particular securities, securities indices and other financial instruments and indices. The Portfolio may engage in futures transactions on U.S. exchanges.

12

The Portfolio may purchase and sell futures contracts, and purchase and write call and put options on futures contracts, in order to seek to increase total return or to hedge against changes in interest rates, securities prices, or to otherwise manage its term structure, sector selections and duration in accordance with its investment objective and policies. The Portfolio may also enter into closing purchase and sale transactions with respect to such contracts and options.

Options on Securities. A put option gives the purchaser of the option the right to sell, and the writer (seller) of the option the obligation to buy, the underlying instrument during the option period. A call option gives the purchaser of the option the right to buy, and the writer (seller) of the option the obligation to sell, the underlying instrument during the option period. The Portfolio may write (sell) call and put options and purchase put and call options on any securities in which the Portfolio may invest.

Writing and purchasing options is a highly specialized activity that involves special investment risks. The Portfolio may use options for either hedging purposes, or to seek to increase total return (which is considered a speculative activity). The successful use of options depends in part on the ability of the Adviser to manage future price fluctuations and the degree of correlation between the options and securities markets. If the Adviser is incorrect in its expectation of changes in market prices or determination of the correlation between the instruments or indices on which options are written and purchased and the instruments in the Portfolio, the Portfolio may incur losses that it would not otherwise incur. The use of options can also increase the Portfolio’s transaction costs. Options written or purchased by the Portfolio may be traded on U.S. exchanges or over-the-counter. Over-the-counter options will present greater possibility of loss because of their greater illiquidity and credit risk. The Portfolio may be required to treat as illiquid certain over-the-counter options purchased and securities being used to cover certain written over-the counter options.

When-Issued Securities and Forward Commitments. The Portfolio may purchase when-issued securities and make contracts to purchase or sell securities for a fixed price at a future date beyond customary settlement time. When-issued securities are purchased after the announcement of the offering but before the issue date of the securities in order to secure what is considered to be an advantageous price and yield to the Portfolio at the time of entering into the transaction. A forward commitment involves the entering into a contract to purchase or sell securities for a fixed price at a future date beyond the customary settlement period.

The purchase of securities on a when-issued or forward commitment basis involves a risk of loss if the value of the securities to be purchased declines before the settlement date. Conversely, the sale of securities on a forward commitment basis involves the risk that the value of the securities sold may increase before the settlement date. Although the Portfolio may purchase securities on a when-issued or forward commitment basis with the intention of acquiring the securities for its portfolio, the Portfolio may dispose of when-issued securities or forward commitments prior to settlement if the Adviser deems it appropriate.

Interest Rate Swaps, Total Return Swaps, Options on Swaps and Interest Rate Caps, Floors and Collars.

13

The Portfolio may enter into the transactions described above for hedging purposes or to seek to increase total return. The use of swaps, swaptions, and interest rate caps, floors and collars is a highly specialized activity which involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. If the Adviser is incorrect in its forecasts of market values and interest rates, the investment performance of the Portfolio would be less favorable than it would have been if these investment techniques were not used.

Short Sales. The Portfolio may engage in short-sales of securities. A short sale is a sale by the Portfolio of a security which has been borrowed from a third party on the expectation that the market price will decline. If the price of the security drops, the Portfolio will make a profit by purchasing the security in the market at a lower price than the price at which it sold the security. If the price of the security rises, the Portfolio may have to cover its short position at a higher price than the short sale price, resulting in a loss to the Portfolio.

Temporary Investments. The Portfolio may depart from its principal investment strategy in response to adverse market, economic, political or other conditions by taking temporary defensive positions in all types of money market securities. If the Portfolio were to take a temporary defensive position, it may be unable for a time to achieve its investment objective.

Investment Risks

The following provides additional information about the principal risks of investing in the Portfolio.

Risks of Fixed Income Securities. These risks include interest rate risk and credit risk. In general, interest rate risk involves the risk that when interest rates decline, the market value of fixed income securities tends to increase (although many mortgage-related securities will have less potential than other debt securities for capital appreciation during periods of declining rates). Conversely, when interest rates increase, the market value of fixed income securities tends to decline. Credit risk involves the risk that the issuer could default on its obligations, and the Portfolio will not recover its investment.

Risks of Mortgage and Related Investments. Mortgage-related securities are particularly exposed to prepayment and extension risks. For example, homeowners have the option to prepay their mortgages. Therefore, the duration of a security backed by home mortgages can either shorten (prepayment risk) or lengthen (extension risk). In general, if interest rates on new mortgage loans fall sufficiently below the interest rates on existing outstanding mortgage loans, the rate of prepayment would be expected to increase. Conversely, if mortgage loan interest rates rise above the interest rates on existing outstanding mortgage loans, the rate of prepayment would be expected to decrease. Small changes in mortgage prepayments can significantly impact the cash flow and the market value of mortgage-related securities. A change in the prepayment rate can result in losses to investors. In addition, particular securities may be leveraged such that their exposure ( i.e. , price sensitivity) to interest rate and/or prepayment risk is magnified.

The yields on stripped mortgage-backed securities that receive all or most of the interest from mortgage loans are generally higher than prevailing market yields on other mortgage-related securities because their cash flow patterns are more volatile and there is a greater risk that the initial investment will not be fully recouped. The market value of stripped mortgage-backed securities consisting entirely of principal payments generally is unusually volatile in response to changes in interest rates. Total return may fluctuate in rising interest rate environments and create greater price volatility. The yield to maturity on an interest-only security is extremely sensitive to the rate of principal payments (including prepayments) on the underlying mortgage assets, and a rapid rate of principal payments may have a material adverse effect on the Portfolio’s yield to maturity from these securities.

Call Risk. The risk that an issuer or borrower will exercise its right to pay principal on an obligation held by the Portfolio earlier than expected. Issuers are more likely to exercise these rights during periods of declining interest rates, because they may be able to issue new lower-coupon instruments. The Portfolio may receive unscheduled prepayments of principal before the security’s maturity date due to voluntary prepayments, refinancing or foreclosure on the underlying mortgage loans. To the Portfolio this means a loss of anticipated interest, and a portion of its principal investment represented by any premium that the Portfolio may have paid. Under these circumstances, the Portfolio may be unable to recoup all of its initial investment and will also suffer from having to reinvest in lower yielding securities. For mortgage-related securities, the early prepayment of principal by all or a portion of the borrowers underlying a mortgage security is functionally equivalent to a full or partial call of the security.

Risks of Derivative Investments. The Portfolio’s transactions, if any, in options, futures, options on futures, options on swaps, swaps and interest rate caps, floors and collars, involve risk of loss. Loss can result from a lack of correlation between changes in the value of derivative instruments and the portfolio assets (if any) being hedged, the potential illiquidity of the markets for derivative instruments, or the risks arising from margin requirements and related leverage factors associated with such transactions. The use of these management techniques also involves the risk of loss if the

14

Adviser is incorrect in its expectation of fluctuations in securities prices or interest rates. Markets for derivatives are highly volatile and the use of derivatives may increase the volatility of the Portfolio’s net asset value and may result in substantial losses to the Portfolio. Certain derivative instruments may be illiquid. Although the Portfolio intends to invest in derivative instruments primarily to hedge against mortgage-related security risks and other risks, the Portfolio may invest in derivative instruments for non-hedging purposes (that is, to seek to increase total return). Investing for non-hedging purposes is considered a speculative practice and presents even greater risk of loss.

Credit/Default Risks. The Portfolio expects to purchase securities rated in one of the two highest rating categories by an NRSRO ( e.g. , Aaa or Aa as rated by Moody’s Investors Service, Inc. or AAA or AA as rated by Standard & Poor’s Rating Group). A security will be deemed to have met a rating requirement if it receives the minimum required rating from at least one NRSRO even though it has been rated below the minimum rating by one or more other rating organizations, or if unrated by such rating organizations, the security is determined by the Adviser to be of comparable credit quality. A security satisfies the Portfolio’s minimum rating requirement regardless of its relative rating (for example, plus or minus) within a designated major rating category. If a security satisfies the Portfolio’s minimum rating requirement at the time of purchase and is subsequently downgraded below that rating, the Portfolio will not be required to dispose of the security. If a downgrade occurs, the Adviser will consider which action, including the sale of the security, is in the best interest of the Portfolio and its shareholders. Debt securities purchased by the Portfolio may include securities issued by the U.S. government (and its agencies, instrumentalities and sponsored enterprises), banks and other issuers.

Leveraging Risks. The use of leverage by the Adviser may increase the volatility of the Portfolio. Mortgage-related securities in which the Portfolio invests may be leveraged. These leveraged instruments may result in losses to the Portfolio or may adversely affect the Portfolio’s net asset value or total return, because instruments that contain leverage are more sensitive to changes in interest rates. The Portfolio may also use borrowed funds to create leverage. Although the use of leverage by the Portfolio may create an opportunity for increased return, it also results in additional risks and can magnify the effect of any losses. If the income and gains earned on the securities and instruments purchased with leverage proceeds are greater than the cost of the leverage, the Portfolio’s return will be greater than if leverage had not been used. Conversely, if the income and gains from the securities and instruments purchased with such proceeds does not cover the cost of leverage, the Portfolio’s return will be less than if leverage had not been used. In the event of a sudden, precipitous drop in value of the Portfolio’s assets, the Portfolio may not be able to liquidate assets quickly enough to pay off its borrowing. Short sales of securities also involve the use of leverage. Using this investment technique may adversely affect the Portfolio’s net asset value or total return.

To limit leverage risk, the Portfolio will segregate assets determined by the Adviser to be liquid in accordance with procedures established by the Board of Directors, or, when permissible, enter into offsetting transactions, to cover its obligations resulting from its use of derivative instruments. Securities held in a segregated account cannot be sold while the futures contract or option is outstanding, unless they are replaced with other suitable assets. As a result, it is possible that segregating a large percentage of the Portfolio’s assets could impede portfolio management or its ability to meet redemption requests or other current obligations.

Risks of Illiquid Securities. The Portfolio generally may invest up to 15% of its net assets in illiquid securities which cannot be disposed of in seven days in the ordinary course of business at fair value. Illiquid securities may include:

Investing in 144A securities may decrease the liquidity of the Portfolio to the extent that qualified institutional buyers become for a time uninterested in purchasing these restricted securities. 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.

Disclosure of Portfolio Holdings

A description of the Company’s policies and procedures with respect to the disclosure of the Portfolio’s securities is available in the SAI.
