The investment seeks to maximize total return, consistent with preservation of capital. The fund pursues its investment objective by investing, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in bonds. Its average portfolio duration may range from negative 2 years to plus 4 years. The fund may invest in derivatives, which are instruments that have a value derived from, or directly linked to, an underlying asset, such as equity securities, fixed-income securities, commodities, currencies, interest rates, or market indices.
