The fund’s investment objective is to provide you with current income exempt from regular federal income tax, consistent with the maturity and quality standards described in this prospectus, and to preserve capital.

This table describes the fees and expenses that you may pay if you buy, hold and sell shares of the fund. You may pay other fees to financial intermediaries, which are not reflected in the tables and examples below.

^* Restated to reflect current fees.

This example is intended to help you compare the cost of investing in the fund with the cost of investing in other mutual funds.

The example assumes that you invest $10,000 in the fund for the time periods indicated and then redeem or hold all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the fund’s operating expenses remain the same. The example reflects the fee waiver and/or expense reimbursement described above (if any) through the expiration of such waiver and/or reimbursement and total annual fund operating expenses thereafter.

The fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund’s investment results. During the most recent fiscal year, the fund’s portfolio turnover rate was 46% of the average value of its portfolio.

Under normal circumstances, the fund will invest at least 80% of its assets in, or derive at least 80% of its income from, securities that are exempt from regular federal income tax and that do not subject you to federal alternative minimum tax. Investments in derivatives may be counted toward the fund’s 80% investment policy to the extent that such derivatives provide investment exposure to the investments included within the policy or to one or more market risk factors associated with such investments. The fund may also invest up to 20% of its assets in “private activity bonds” whose interest is generally subject to the federal alternative minimum tax.

The fund invests primarily in debt securities rated A- or better or A3 or better by Nationally Recognized Statistical Rating Organizations designated by the fund’s investment adviser, or unrated but determined by the fund’s investment adviser to be of equivalent quality. The fund may also invest in debt securities rated BBB and Baa by Nationally Recognized Statistical Rating Organizations designated by the fund’s investment adviser, or unrated but determined by the fund’s investment adviser to be of equivalent quality. The dollar-weighted average effective maturity of the fund’s portfolio is between one and 10 years. In calculating the effective maturity or average life of a particular debt security, a put, call, sinking fund or other feature will be considered to the extent it results in a security whose market characteristics indicate an effective maturity or average life that is shorter than its nominal or stated maturity. The investment adviser will consider the impact on effective maturity of potential changes in the financial condition of issuers and in market interest rates in making investment selections for the fund.

The investment adviser uses a system of multiple portfolio managers in managing the fund’s assets. Under this approach, the portfolio of the fund is divided into segments managed by individual managers.

The fund relies on the professional judgment of its investment adviser to make decisions about the fund’s portfolio investments. The basic investment philosophy of the investment adviser is to seek to invest in attractively priced securities that, in its opinion, represent good, long-term investment opportunities. Securities may be sold when the investment adviser believes that they no longer represent relatively attractive investment opportunities.

The following bar chart shows how investment results for the Class R-6 shares of the fund have varied from year to year, and the following table shows how the Class R-6 shares’ average annual total returns for various periods compare with a broad measure of securities market results and, if applicable, other measures of market results that reflect the fund’s investment universe. This information provides some indication of the risks of investing in the fund. Past investment results (before and after taxes) are not predictive of future investment results.
