Fund profile

As filed in the prospectus · 2025 Q4

The fund seeks a high level of income exempt from federal income taxes.

Strategy · summarised

The fund invests at least 80% of its assets in investment-grade municipal securities, with most holdings in long-term maturities exceeding 10 years, and may allocate up to 20% to below-investment-grade municipal bonds. The fund targets at least 80% of income exempt from federal income taxes, though a significant portion may be subject to the alternative minimum tax. Portfolio decisions reflect the managers' outlook on interest rates, economic conditions, and relative value across municipal sectors including health care, transportation, utilities, and private activity bonds. Because the fund may hold a significant portion of assets in specialized sectors, concentration risk in those areas may affect returns.

These classes hold the same portfolio, so the 1.86pp spread over 5 years is the cost difference between them — roughly 0.37pp a year — not a difference in what they own.

These three overlap — one holding can be in arrears and paying in kind at once — so they are shown separately and never summed.

Risk profile

Interest-rate and credit-spread sensitivity, both in years · as of 2026Q2

Most of this fund’s sensitivity is to interest rates, with credit spreads carrying nearly as much.

Interest-rate duration
7.72 yr
approx. move per 100bp
Credit-spread duration
7.51 yr
approx. move per 100bp
If rates and spreads both rise 100bp

Where the loss would come from. The two shocks are the same size, so this is the balance of the fund's two sensitivities rather than a bet on one moving more.

Interest rates51%
Credit spreads49%

Filers report the impact of a 0.01% move only, so the total is our own scaling of that one number and overstates the loss on most bonds — read it as approximate, never as precise. The two sensitivities overlap rather than add up: they measure the same positions against different shocks, which is why the durations above are shown side by side and never summed.

Share of duration at each point, shortest first. A positive figure loses value when spreads widen; a negative one offsets — a credit hedge.

The two bands measure the same positions against different shocks and do not add — a Treasury carries rate duration and no spread duration, a floating-rate credit the reverse. Rate tenors are also summed across every currency the fund discloses.
