The investment seeks total return by investing primarily in domestic and foreign debt securities. The fund normally invests at least 80% of its assets (net assets plus any borrowings for investment purposes) in a diversified portfolio of debt or debt-related securities. The average portfolio duration of the fund will normally vary from 0 to 7 years. The fund may invest in derivatives, such as futures, options, forward commitments and interest rate swap agreements to try to enhance returns or reduce the risk of loss by hedging certain of its holdings or manage duration. It may invest up to 25% of its total assets in swaps.
