Fund profile

As filed in the prospectus · 2026 Q2

The Fund seeks as high a level of current income exempt from federal income tax as is consistent with relative stability of principal.

Strategy · summarised

The fund invests at least 80% of its assets in municipal securities whose interest is exempt from federal income tax, with an average weighted maturity of two years or less, selecting primarily investment-grade or unrated equivalent securities while allowing up to 10% in below-investment-grade bonds. The adviser uses a value-oriented approach, analyzing individual securities for interest rate risk, credit risk, duration, and liquidity, and also considers environmental, social and governance factors as financially material to municipal issuers. Because securities purchased at investment grade may be downgraded after purchase, the fund's credit quality can deteriorate over time.

May 2026 has been filed since the trailing figures were struck, so it is 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

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

Interest-rate duration
0.90 yr
approx. move per 100bp
Credit-spread duration
0.88 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.

≈ -2.0%
of value
Interest rates50%
Credit spreads50%

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.
