s and CLOs and other similarly structured securities See “The Fund’s Investment Objectives and Strategies-Portfolio Contents and Other Information-Mortgage-Related and Other Asset-Backed Instruments” in this prospectus and “Investment Objectives and Policies-Mortgage-Related and Other Asset-Backed Instruments” in the Statement of Additional Information for a description of the various mortgage-related and other asset-backed instruments in which the Fund may invest and their related risks. Mortgage-related and other asset-backed instruments represent interests in “pools” of mortgages or other assets such as consumer loans or receivables held in trust and often involve risks that are different from or possibly more acute than risks associated with other types of debt instruments. Generally, rising interest rates tend to extend the duration of fixed rate mortgage-related assets, making them more sensitive to changes in interest rates. Compared to other fixed income investments with similar maturity and credit, mortgage-related securities may increase in value to a lesser extent when interest rates decline and may decline in value to a similar or greater extent when interest rates rise. As a result, in a period of rising interest rates, the Fund may exhibit additional volatility since individual mortgage holders are less likely to exercise prepayment options, thereby putting additional downward pressure on the value of these securities and potentially causing the Fund to lose money. This is known as extension risk. Mortgage-backed securities can be highly sensitive to rising interest rates, such that even small movements can cause the Fund to lose value. Mortgage-backed securities, and in particular those not backed by a government guarantee, are subject to credit risk. When interest rates decline, borrowers may pay off their mortgages sooner than expected. This can reduce the returns of the Fund because the Fund may have to reinvest that money at the lower prevailing interest rates. The Fund’s investments in other asset-backed instruments are subject to risks similar to those associated with mortgage-related assets, as well as additional risks associated with the nature of the assets and the servicing of those assets. Payment of principal and interest on asset-backed instruments may be largely dependent upon the cash flows generated by the assets backing the instruments, and asset-backed instruments may not have the benefit of any security interest in the related assets. Subordinate mortgage-backed or asset-backed instruments are paid interest only to the extent that there are funds available to make payments. To the extent the collateral pool includes a large percentage of delinquent loans, there is a risk that interest payment on subordinate mortgage-backed or asset-backed instruments will not be fully paid. There are multiple tranches of mortgage
