The investment seeks to provide investors with a high level of current income and total return. Under normal circumstances, the fund invests at least 80% of its net assets in a diversified portfolio of high-yield bonds. For purposes of this 80% policy, high-yield bonds include, without limitation, bonds, debt instruments, and other fixed income and income-producing debt instruments, of any kind, issued or guaranteed by governmental or private-sector entities that are rated below investment grade by one or more nationally recognized statistical rating organizations or, if unrated, determined by the fund to be of comparable quality.
