These securities include, but are not limited to, fixed or floating-rate mortgage-backed securities (MBS) including collateralized mortgage obligations, issued, backed or otherwise guaranteed by the U.S. Government or its agencies or instrumentalities, Treasuries and agency bonds. The Fund may invest up to 10% of its net assets in other income securities, including, but not limited to, non-agency MBS and asset-backed securities, corporate bonds, loans and money market securities. The Fund many invest in securities in any ratings category, including securities rated below investment grade or in unrated securities considered to be of comparable quality by the investment adviser (commonly referred to as junk bonds). The Funds dollar-weighted average duration will not exceed three years. The Fund is not a money market fund and does not seek to maintain a stable net asset value per share. The Fund may invest in stripped securities which may be issued by the ?U.S. Government, its agencies or instrumentalities, and may also be issued by private originators or investors, including depository institutions, banks, investment banks and special purpose subsidiaries of these entities. The Fund may also engage in derivative transactions. Transactions in derivative instruments may include: the purchase or sale of futures contracts on securities, indices or other financial instruments or currencies; options on futures contracts; exchange-traded and over-the-counter options on securities, indices, currencies and other instruments; and interest rate, credit default, inflation and total return swaps. The Fund may take short or long positions with regard to certain synthetic total return swap indices. The Fund may use interest rate swaps and options on interest rate swaps for risk management purposes and not as a speculative investment and would typically use interest rate swaps to shorten the average interest rate reset time of its holdings. The Fund may engage in other derivatives to seek return, to hedge against fluctuations in securities prices, interest rates or currency exchange rates, to change the duration of obligations held by the Fund, to manage certain investment risks and/or as a substitute for the purchase or sale of securities or currencies. Except as required by applicable regulation, there is no stated limit on the Funds use of derivatives for such purposes. The Fund may engage in borrowing and active management techniques. The Fund is authorized to borrow to acquire additional investments when it believes that the interest payments and other costs with respect to such borrowings will be exceeded by the anticipated total return on such investments. The Fund may enter into forward commitments to buy or sell agency MBS (to-be-announced transactions, or TBAs). In addition, the Fund at times may enter into mortgage dollar rolls. The Fund may engage in short sales of securities and in repurchase and reverse repurchase agreements. The portfolio managers seek to purchase securities believed to be the best relative value with regard to price, yield, and expected total return in relation to other available instruments. Investment decisions are primarily made on the basis of fundamental research and relative value. The portfolio managers may sell a security when he believes the security no longer represents the best relative value and the fundamental research or cash needs dictate. When deemed by the investment adviser to be relevant to its evaluation of creditworthiness and when applicable information is available, the investment adviser considers environmental, social and/or governance issues (referred to as ?ESG) which may impact the prospects of an issuer (or obligor) or financial performance of an obligation. When considered, one or more ESG issues are taken into account alongside other factors in the investment decision-making process and are not the sole determinant of whether an investment can be made or will remain in the Funds portfolio.
