The fund invests, under normal circumstances, at least 80% of its net assets plus any borrowings for investment purposes in income-producing securities. Such securities may be rated at any level by nationally recognized statistical rating organizations, or they may be unrated. The fund’s portfolio will typically include a high proportion, up to 100%, of high-yield/high-risk securities rated below investment grade. Such securities are sometimes called “junk bonds.” Junk bonds are considered speculative investments.
