Principal Risk Factors: Risks are inherent in all investing. Certain risks applicable to the Fund are identified below, which includes the risk that you could lose some or all of your investment in the Fund. The principal risks of investing in the Fund are spelled out in the Fund's annual shareholder reports. The order of the below risk factors does not indicate the significance of any particular risk factor. The Fund also files reports, proxy statements and other information that is available for review.

Past performance is no assurance of future results. Investment return and market value of an investment in the Fund will fluctuate. Shares, when sold, may be worth more or less than their original cost. There can be no assurance that the Fund's investment objectives will be achieved. The Fund may not be appropriate for all investors.

Market risk is the risk that a particular investment, or shares of a fund in general may fall in value. Investments held by the Fund are subject to market fluctuations caused by real or perceived adverse economic conditions, political events, regulatory factors or market developments, changes in interest rates and perceived trends in securities prices. Shares of a fund could decline in value or underperform other investments as a result. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious disease or other public health issues, recessions, natural disasters or other events could have significant negative impact on a fund and its investments.

Current market conditions risk is the risk that a particular investment, or shares of the fund in general, may fall in value due to current market conditions. For example, changes in governmental fiscal and regulatory policies, disruptions to banking and real estate markets, actual and threatened international armed conflicts and hostilities, and public health crises, among other significant events, could have a material impact on the value of the fund's investments.

The debt securities in which the Fund invests are subject to certain risks, including issuer risk, reinvestment risk, prepayment risk, credit risk, interest rate risk and liquidity risk. Issuer risk is the risk that the value of fixed-income securities may decline for a number of reasons which directly relate to the issuer. Reinvestment risk is the risk that income from the Fund's portfolio will decline if the Fund invests the proceeds from matured, traded or called bonds at market interest rates that are below the Fund portfolio's current earnings rate. Prepayment risk is the risk that, upon a prepayment, the actual outstanding debt on which the Fund derives interest income will be reduced. Credit risk is the risk that an issuer of a security will be unable or unwilling to make dividend, interest and/or principal payments when due and that the value of a security may decline as a result. Interest rate risk is the risk that fixed-income securities will decline in value because of changes in market interest rates. Liquidity risk is the risk that illiquid and restricted securities may be difficult to value and to dispose of at a fair price at the times when the Fund believes it is desirable to do so.

A mortgage-backed security may be negatively affected by the quality of the mortgages underlying such security and the structure of its issuer. For example, if a mortgage underlying a particular mortgage-backed security defaults, the value of that security may decrease. Moreover, a downturn in the markets for residential or commercial real estate or a general economic downturn could negatively affect both the price and liquidity of privately issued mortgage-backed securities. A portion of the Fund's managed assets may be invested in subordinated classes of mortgage-backed securities. Such subordinated classes are subject to a greater degree of non-payment risk than are senior classes of the same issuer or agency.

Investments in asset-backed or mortgage-backed securities offered by non-governmental issuers, such as commercial banks, savings and loans, private mortgage insurance companies, mortgage bankers and other secondary market issuers are subject to additional risks.

The primary risks associated with the use of futures contracts are (a) the imperfect correlation between the change in market value of the instruments or indices underlying the futures contracts and the price of the futures contracts; (b) possible lack of a liquid secondary market for a futures contract and the resulting inability to close a futures contract when desired; (c) losses caused by unanticipated market movements, which are potentially unlimited; (d) the investment adviser's inability to predict correctly the direction of securities prices, interest rates, currency exchange rates and other economic factors; and (e) the possibility that the counterparty will default in the performance of its obligations.

If a security sold short increases in price, the Fund may have to cover its short position at a higher price than the short sale price, resulting in a loss.

Repurchase agreements are subject to the risk of failure. If the Fund's counterparty defaults on its obligations and the Fund is delayed or prevented from recovering the collateral, or if the value of the collateral is insufficient, the Fund may realize a loss.

Use of leverage can result in additional risk and cost, and can magnify the effect of any losses.

The risks of investing in the Fund are spelled out in the shareholder reports and other regulatory filings.
