The investment seeks a high level of current income; capital appreciation is the secondary consideration. The fund normally invests primarily in income producing debt securities, preferred stocks, and convertible securities, with an emphasis on lower-quality debt securities. It normally invests primarily in securities rated BB or B by Standard & Poor's (S&P), Ba or B by Moody's Investors Service (Moody's), comparably rated by at least one nationally recognized credit rating agency, or, if unrated, considered by Fidelity Management & Research Company (FMR) to be of comparable quality. The fund normally maintains a duration of three years or less.
