Fund profile

As filed in the prospectus · 2026 Q1

The investment objective of the Fund is to seek a high level of income exempt from federal income tax.

Strategy · summarised

The fund invests at least 80% of its net assets in municipal bonds exempt from federal income tax, with at least 50% in below-investment-grade bonds rated BBB+/Baa1 or lower, emphasizing high-yield municipal debt. The fund may also hold defaulted and distressed securities, unrated bonds, and inverse floaters providing leveraged exposure to municipal bonds. Because the fund concentrates on lower-rated and potentially unrated municipal bonds, credit deterioration in its holdings can materially affect returns.

Return profile

Chart:

Total return as filed — price change plus distributions reinvested · trailing figures to Apr 2026

Share class1-year3-year5-yearVolWorst fall

+5.70%+15.79%+3.28%4.91%-6.79%

These classes hold the same portfolio, so the 4.45pp spread over 5 years is the cost difference between them — roughly 0.89pp 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.

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

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
7.79 yr
approx. move per 100bp
Credit-spread duration
8.13 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.

of value
Credit spreads51%
Interest rates49%

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.
