Factors Affecting Performance [Text Block]

How did the Fund perform last year and what affected its performance? 

Class A shares of the Fund returned 6.81% (unadjusted for sales charges) for the period ended May 31, 2026. The Fund's index, the Bloomberg Municipal Bond Index, returned 6.67% for the same period.

While municipal bond market performance continued to be pressured over the period by elevated new issue supply, this was offset by strong demand from tax-free exchange traded funds and separately managed accounts. Yields finished lower along the municipal curve, supporting performance for tax-free bonds broadly.

The Fund was overweight issues rated BBB (the lowest investment grade category) which proved additive as this ratings category led performance within the investment grade municipal market. In sector terms, overweight allocations to senior living, hospital and airport bonds aided performance. In addition, security selection was positive within both longer maturity and below investment grade issues.

On the downside, underweight allocations to utility and general obligation bonds detracted from return. In addition, security selection within the transportation sector weighed on performance.

Credit Ratings Selection [Text Block] The quality ratings represent the highest of Moody’s Investors Service, Inc. (“Moody’s”), Fitch Ratings, Inc. (“Fitch”) or S&P Global Ratings (“S&P”) credit ratings. The ratings of Moody’s, Fitch and S&P represent their opinions as to the quality of the securities they rate. Credit quality measures a bond issuer’s ability to repay interest and principal in a timely manner. Ratings are relative and subjective and are not absolute standards of quality. Credit quality does not remove market risk and is subject to change.

Factors Affecting Performance [Text Block]

How did the Fund perform last year and what affected its performance? 

Class C shares of the Fund returned 6.00% (unadjusted for sales charges) for the period ended May 31, 2026. The Fund's index, the Bloomberg Municipal Bond Index, returned 6.67% for the same period.

While municipal bond market performance continued to be pressured over the period by elevated new issue supply, this was offset by strong demand from tax-free exchange traded funds and separately managed accounts. Yields finished lower along the municipal curve, supporting performance for tax-free bonds broadly.

The Fund was overweight issues rated BBB (the lowest investment grade category) which proved additive as this ratings category led performance within the investment grade municipal market. In sector terms, overweight allocations to senior living, hospital and airport bonds aided performance. In addition, security selection was positive within both longer maturity and below investment grade issues.

On the downside, underweight allocations to utility and general obligation bonds detracted from return. In addition, security selection within the transportation sector weighed on performance.

Performance Past Does Not Indicate Future [Text] The Fund's past performance is not a good predictor or guarantee of the Fund's future performance.

Factors Affecting Performance [Text Block]

How did the Fund perform last year and what affected its performance? 

Class S shares of the Fund returned 6.92% for the period ended May 31, 2026. The Fund's index, the Bloomberg Municipal Bond Index, returned 6.67% for the same period.

While municipal bond market performance continued to be pressured over the period by elevated new issue supply, this was offset by strong demand from tax-free exchange traded funds and separately managed accounts. Yields finished lower along the municipal curve, supporting performance for tax-free bonds broadly.

The Fund was overweight issues rated BBB (the lowest investment grade category) which proved additive as this ratings category led performance within the investment grade municipal market. In sector terms, overweight allocations to senior living, hospital and airport bonds aided performance. In addition, security selection was positive within both longer maturity and below investment grade issues.

On the downside, underweight allocations to utility and general obligation bonds detracted from return. In addition, security selection within the transportation sector weighed on performance.

Performance Past Does Not Indicate Future [Text] The Fund's past performance is not a good predictor or guarantee of the Fund's future performance.

Factors Affecting Performance [Text Block]

How did the Fund perform last year and what affected its performance? 

Institutional Class shares of the Fund returned 6.92% for the period ended May 31, 2026. The Fund's index, the Bloomberg Municipal Bond Index, returned 6.67% for the same period.

While municipal bond market performance continued to be pressured over the period by elevated new issue supply, this was offset by strong demand from tax-free exchange traded funds and separately managed accounts. Yields finished lower along the municipal curve, supporting performance for tax-free bonds broadly.

The Fund was overweight issues rated BBB (the lowest investment grade category) which proved additive as this ratings category led performance within the investment grade municipal market. In sector terms, overweight allocations to senior living, hospital and airport bonds aided performance. In addition, security selection was positive within both longer maturity and below investment grade issues.

On the downside, underweight allocations to utility and general obligation bonds detracted from return. In addition, security selection within the transportation sector weighed on performance.

Performance Past Does Not Indicate Future [Text] The Fund's past performance is not a good predictor or guarantee of the Fund's future performance.

Credit Ratings Selection [Text Block] The quality ratings represent the highest of Moody’s Investors Service, Inc. (“Moody’s”), Fitch Ratings, Inc. (“Fitch”) or S&P Global Ratings (“S&P”) credit ratings. The ratings of Moody’s, Fitch and S&P represent their opinions as to the quality of the securities they rate. Credit quality measures a bond issuer’s ability to repay interest and principal in a timely manner. Ratings are relative and subjective and are not absolute standards of quality. Credit quality does not remove market risk and is subject to change.
