Fund profile

As filed in the prospectus · 2026 Q1

The investment objective of the Fund is to seek the maximum amount of interest income exempt from federal income tax as is consistent with reasonable risk.

Strategy · summarised

The fund invests at least 80% of net assets in municipal bonds paying interest exempt from federal income tax, with a focus on investment-grade credits rated BBB/Baa or higher but permitted to hold up to 35% in below-investment-grade bonds. The portfolio management team emphasizes credit analysis, tax-exempt yield, total return, interest rate risk, and call protection, with a target dollar-weighted average maturity between twelve and twenty-five years. Because security selection depends on the manager's credit assessment and market outlook, fund performance will diverge from any benchmark. The fund may invest up to 20% of assets in inverse floaters, which provide leveraged exposure to municipal bonds whose interest rates move inversely with short-term tax-exempt rates.

+5.93%+11.78%+2.01%4.64%-6.33%

These classes hold the same portfolio, so the 4.39pp spread over 5 years is the cost difference between them — roughly 0.88pp a year — not a difference in what they own.

Cumulative return· Jul 2023 – Apr 2026

May 2026 and Jun 2026 have been filed since the trailing figures were struck, so they are not in the table above or the curve — every figure here shares one cut-off, which is what makes them comparable with other funds.

Risk profile

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

More of this fund’s sensitivity sits in credit spreads than in interest rates — a rate rally that comes with a credit selloff works against it.

Interest-rate duration
7.48 yr
approx. move per 100bp
Credit-spread duration
8.04 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.

Credit spreads52%
Interest rates48%

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.

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.
