| Factors Affecting Performance [Text Block] | Management's discussion of fund performance The fund’s Class capitalgroup.com/mutual-fund-returns-A What factors influenced results Toward the end of 2023, the municipal bond market rallied alongside declining U.S. Treasury yields. With investors in the market more willing to take on risk during the last year, lower quality bonds significantly outpaced their higher quality counterparts, despite the elevated rate volatility. High-yield municipals outpaced investment-grade issues by over 5.6%, according to the Bloomberg Municipal High Yield Bond Index and the Bloomberg Municipal Index, respectively. Each of the fund’s sectors provided positive returns to the portfolio. The fund’s holdings in corporates, housing and education debt were particularly additive during the period. Likewise, holdings in health care and utility bonds were meaningful contributors, despite lagging the portfolio’s overall return. From a rating perspective, investment-grade bonds saw returns surpassing those of the overall portfolio except for AA-rated bonds. Duration positioning negatively impacted the fund’s overall results.

| [1]Bond ratings, which typically range from AAA/Aaa (highest) to D (lowest), are assigned by credit rating agencies such as Standard & Poor’s, Moody’s and/or Fitch as an indication of an issuer’s creditworthiness. In assigning a credit rating to a security, the fund looks specifically to the ratings assigned to the issuer of the security by Standard & Poor’s, Moody’s and/or Fitch. If agency ratings differ, the security will be considered to have received the highest of those ratings, consistent with the fund’s investment policies.[2]Includes derivatives. | ||
