Fund Descriptions
Short-Term Bond Fund

“This Fund has a short weighted average maturity (no more than three years), which should reduce the impact of interest rate changes on the Fund’s share price,” portfolio manager Douglas Kern explains.

Mr. Kern ordinarily invests at least 80% of the assets of the Short-Term Bond Fund in bonds that are in the three highest credit categories. The Fund can hold U.S. government securities as well as corporate bonds and other types of debt instruments.

He says this Fund is suitable for those who want an investment that is designed to deliver a higher return than a money market fund, but with fewer ups and downs in share price than a longer-term bond fund.
