The investment seeks total return through capital appreciation and current income. The fund invests mainly in a globally-diversified portfolio of convertible securities (including synthetic convertible instruments) issued by both U.S. and foreign companies without regard to market capitalization. Under normal circumstances, it invests at least 80% of its net assets (plus borrowings for investment purposes, if any) in convertible securities, including synthetic convertible securities. The fund may invest up to 20% of its net assets in equity securities or securities with economic characteristics similar to stock or the equity markets.
