The fund's objective is to provide an attractive total return primarily through high current income and secondarily through capital appreciation. The Fund's principal investment strategy is to primarily invest its assets in a broad range of U.S. dollar-denominated high-yield securities, including bonds (often referred to as "junk" bonds), convertible securities, leveraged loans, or preferred stocks, with an emphasis on non-investment-grade debt securities. Although the fund will invest primarily in U.S. securities, it may invest without limit in dollar-denominated foreign securities and to a limited extent in non-dollar-denominated foreign securities, including in each case emerging markets securities.
