The investment seeks total return, and secondarily, current income. The fund normally invests at least 80% of its net assets (including any borrowings for investment purposes) in U.S. high yield instruments (commonly referred to as "junk" bonds), which are debt instruments that are, at the time of purchase, rated below investment grade by a credit rating agency, or, if not rated by any major credit rating agency, deemed to be below investment grade by T. Rowe Price.
