Under normal market conditions, the fund will invest at least 80% of its net assets in fixed income securities, bank loans and other instruments issued by companies that are rated below investment grade. It generally invests in high yield instruments rated CCC or better by S&P or Moody's, but retains the discretion to invest in even lower rated instruments. The fixed income securities, bank loans and other instruments in which the fund invests include traditional corporate bonds, U.S. government obligations and bank loans to corporate borrowers, and may have fixed, floating or variable rates.
