The fund normally invests at least 80% of its net assets (including any borrowings for investment purposes) in bonds. It seeks to invest in a diversified portfolio of high yield bonds, also known as "junk" bonds, and other high income producing instruments. Junk bonds are bonds that are rated below investment grade (BB and lower, or an equivalent rating) by established credit rating agencies or, if unrated, deemed to be below investment grade by T. Rowe Price.
