Fund Performance Summary

Bond Funds have the same interest rate, high yield and credit risks associated with the underlying bonds in the portfolio, all of which could reduce the Fund's value. As interest rates rise, the value of the Fund can decline and an investor can lose principal.

All indexes listed are unmanaged, and are not available for direct investment. Unlike a mutual fund, the performance of an index assumes no taxes, transaction costs, management fees, or other expenses. The securities in the fund may differ substantially from those in the index.

The SEC yield is the average annualized net investment income per share for the 30-day period ended on the last day of the month.
