The fund’s investment objective is to provide you with a high level of current income exempt from regular federal income tax.

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, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the tables and examples below. For example, in addition to the fees and expenses described below, you may also be required to pay brokerage commissions on purchases and sales of Class F-2 or F-3 shares of the fund. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $100,000 in American Funds and Capital Group KKR Public-Private+ Funds (collectively “Capital Group Funds”). More information about these and other discounts is available from your financial professional, in the “Sales charge reductions and waivers” sections on page 49 of the prospectus and on page 91 of the fund’s statement of additional information, and in the sales charge waiver appendix to the prospectus.

^* A contingent deferred sales charge of 0.75% applies on certain redemptions made within 18 months following purchases of $250,000 or more made without an initial sales charge. Contingent deferred sales charge is calculated based on the lesser of the offering price and market value of shares being sold.

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. You may be required to pay brokerage commissions on your purchases and sales of Class F-2 or F-3 shares of the fund, which are not reflected in the example.

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 32% of the average value of its portfolio.

In seeking to achieve its objective, the fund may accept risks to capital value deemed prudent by the fund's investment adviser to take advantage of opportunities for higher current income on municipal bonds. Municipal bonds are debt obligations that pay interest that is exempt from federal taxation, with payments made from a wide variety of sources, including governmental revenue streams and private enterprises.

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. 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 invest, without limitation, in “private activity bonds” whose interest is generally subject to the federal alternative minimum tax. The fund invests at least 50% of its portfolio in debt securities rated BBB+ or below or Baa1 or below 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. Securities rated BB+ or below and Ba1 or below are sometimes referred to as “junk bonds.”

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 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 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.
