 benefit from further increases in interest rates. Moreover, when interest rates are in excess of coupon rates (i.e., the rates being paid by mortgagors) of the mortgages, ARMBSs behave more like fixed-income securities and less like adjustable rate securities and are subject to the risks associated with fixed-income securities. In addition, during periods of rising interest rates, increases in the coupon rate of adjustable rate mortgages generally lag current market interest rates slightly, thereby creating the potential for capital depreciation on such securities.

Stripped Mortgage-Backed Securities.SMBS are derivative multi-class mortgage securities. SMBS may be 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, mortgage banks, commercial banks, investment banks, and special purpose entities of the foregoing. SMBS are usually structured with two classes that receive different proportions of the interest and principal distributions on a pool of mortgage assets. A common type of SMBS will have one class receiving some of the interest and most of the principal from the mortgage assets, while the other class will receive most of the interest and the remainder of the principal. In the most extreme case, one class will receive all of the interest (the interest-only or “IO” class), while the other class will receive all of the principal (the principal-only or “PO” class). The value of an IO class is extremely sensitive to the rate of principal payments (including prepayments) on the related underlying mortgage assets, and a rapid rate of principal payments may cause the Fund to lose money. The value of a PO class generally increases as interest rates decline and prepayment rates rise. Some IOs and POs are structured to have special protections against the effects of prepayments. These structural protections, however, normally are effective only within certain ranges of prepayment rates and, thus, will not protect investors in all circumstances. The price of these securities typically is more volatile than that of coupon-bearing bonds of the same maturity.

Other Mortgage-Related Securities.Other mortgage-related securities include securities other than those described above that directly or indirectly represent a participation in, or are secured by and payable from, mortgage loans on real property, including mortgage dollar rolls/buy backs, CMO residuals or SMBS. Other mortgage-related securities may be equity or debt 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
