The bar chart below shows how the fund’s investment results have varied from year to year, and the following table shows how the fund’s average annual total returns for various periods compared to that of one or more indices. The Bloomberg US Aggregate Bond Index serves as the fund’s regulatory index and provides a broad measure of market performance. The fund generally invests in securities that are included in the Bloomberg US Government/Credit 1-5 Year Index. The fund does not seek to track the regulatory index. This information provides some indication of the risks of investing in the fund. All figures assume distributions were
reinvested. Keep in mind that future performance (both before and after taxes) may differ from past performance. For current performance information, please see
