American Funds Tax-Exempt Bond’s multimanager structure and deep municipal research bench support a valuation-driven approach that has consistently rewarded investors over the long term.
Capital Group’s multimanager system gives this experienced management team multiple avenues to express investment views while drawing on the firm’s deep bench of analysts, traders, and risk specialists for additional insights. The strategy’s three named managers each run a separate slice of the portfolio, while the analyst bench collectively manages the remaining assets. In his role as principal investment officer, Karl Zeile, who has managed this strategy since 2003, ensures portfolio exposures remain balanced and aligned with the strategy’s parameters. Managers Courtney Wolf and Lee Chu bring deep municipal sector expertise gained over their long Capital Group tenures. The trio taps into 10 muni credit analysts, six traders, and the firm’s risk and quantitative group. This structure lets managers and analysts clearly express their views while limiting the portfolio’s dependence on any one investor.
The managers pursue bonds with attractive relative valuations while keeping portfolio risks measured and within the strategy’s investment-grade muni opportunity set. They run the portfolio as a longer-maturity, higher-yielding offering, typically taking more interest rate risk (as measured by duration) than the muni national intermediate Morningstar Category peer median while staying close to the Bloomberg Municipal Bond Index. They will also buy below-investment-grade rated bonds (and nonrated debt) when valuations justify the risk, but they cap exposure to these bonds at 10% of assets and avoid leverage to limit a potential source of volatility.
The managers favor revenue bonds backed by steady cash flows, but they do not take a static approach to sector positioning. Strong credit research allows them to adjust exposures nimbly as valuations and fundamentals change, as shown by the larger housing allocation, which rose to 15% of assets by December 2025 from 10% at year-end 2020.
This measured approach has delivered strong long-term results. Since January 2004 (Zeile’s first full month on the strategy), the F3 shares’ 3.5% annualized gain through April 2026 outpaced almost 90% of its distinct peers, and its information ratio (a measure of excess return over excess standard deviation versus the benchmark) topped nearly all offerings in that group.
