The investment seeks total return and preservation of capital. The fund invests at least 80% of its net assets in U.S. dollar-denominated investment-grade fixed-income securities either directly or indirectly through exchange-traded funds and other registered investment companies. The fund may invest, without limitation, in mortgage- or asset-backed securities, including to-be-announced transactions, and purchase and sell securities on a when-issued, delayed delivery or forward commitment basis.
