The investment seeks to maximize current yield consistent with prudent investment management. The Fund invests under normal circumstances at least 80% of assets in a diversified portfolio of variable and floating-rate securities, securities with durations of less than or equal to one year, and fixed-rate securities with respect to which the fund has entered into derivative instruments to effectively convert the fixed-rate interest payments into floating-rate interest payments. It may also invest in other Fixed-Income Instruments. The fund may invest all of assets in high-yield securities (?junk bonds?).
