The fund typically allocates a minimum of 80% of its total assets (including any capital acquired through borrowing for investment) to a diverse array of bonds and other fixed-income securities. Its primary holdings consist of corporate bonds, U.S. Treasury securities, and debt instruments from supranational organizations, with a strong emphasis placed on corporate debt. The portfolio may also incorporate obligations from U.S. government agencies, mortgage-backed securities (both commercial and residential), and various other asset-backed securities. While the majority of its investments are in domestic securities, a smaller portion may be allocated to U.S. dollar-denominated foreign securities.
