The Bond Fund normally invests at least 80% of its net assets plus any borrowing for investment purposes in a diversified portfolio of bonds, including corporate bonds of domestic and foreign issuers payable in U. S. dollars, short-term debt instruments, mortgage-related securities, and U. S. Treasury securities and other debt securities issued or guaranteed by the U. S. Government (including its agencies and instrumentalities). Although the Bond Fund invests primarily in investment-grade debt securities (i. e., those rated in the four highest rating categories by S&P or Moody’s), it may invest up to 10% of its net assets in bonds rated below investment grade . In the aggregate, these below investment-grade bonds, along with the other bonds in the Fund’s portfolio, will comprise at least 80% of the Fund’s net assets plus any borrowing for investment purposes. The Bond Fund may invest up to 20% of its net assets in other non-debt securities which include convertible bonds, common stocks and variable-rate demand notes.

Mutual fund investing involves risk, principal loss is possible. Investments in debt securities typically decrease in value when interest rates rise. The risk is usually greater for longer-term debt securities.  Investments in Asset Backed and Mortgage Backed Securities include additional risks that investors should be aware of such as credit risk, prepayment risk, possible illiquidity and default, as well as increased susceptibility to adverse economic development   Investments in bonds of foreign issuers involve greater volatility, political and economic risks, and differences in accounting methods  Investment by the Fund in lower-rated and non-rated securities presents a greater risk of loss to principal and interest than higher-rated securities.  Results include the reinvestment of all dividends and capital gains distributions.
