The investment seeks current income consistent with the preservation of capital. Under normal circumstances, the fund will invest at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in debt securities. These debt securities may include U.S. government securities (including agency securities, and securities issued by government-sponsored enterprises such as Fannie Mae and Freddie Mac, including their mortgage-backed securities), corporate debt securities, other mortgage-backed securities, asset-backed securities and securities issued by foreign governments, which may include sovereign debt.
