Factors Affecting Performance [Text Block]

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

For the 12 months that ended June 30, 2026, the Fund outperformed its benchmark, benefiting from a volatile macro backdrop. Growth moderated as tariff front-loading and artificial intelligence (AI) investment supported resilience in the second half of 2025, before the Middle East conflict drove an energy-led inflation surge in the first half of 2026, which prompted central banks to adjust their policy. The U.S. dollar gained strength, balancing Federal Reserve easing against safe-haven demand, while global bonds lagged on a sharp March selloff as inflation fears reignited.

Foreign exchange (FX) and commodity trend/carry led performance: FX carry, commodity curve momentum, FX momentum, and cross-asset trend (a strategy seeking efficient diversification) were top contributors, led by a short position in Korean won, short on UK/Japanese rates, long precious metals, long natural gas/gas-oil, and long the Brazilian real and South African rand while short the euro, Japanese yen, and Swiss franc. FX value detracted along with rates reversal, commodity positioning, and mean reversion, short the Australian dollar while long Australian rates, and long U.S. wholesale gasoline.

Factors Affecting Performance [Text Block]

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

Top contributors to Fund performance during the period were duration and credit positioning, particularly AA-rated names, as well as security selection within the education, special tax, and resource recovery sectors. We believe that an active approach will continue to benefit shareholders as the potential for further market volatility remains and thoughtful positioning of portfolios can help navigate uncertain markets.

Factors Affecting Performance [Text Block]

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

The Fund underperformed its benchmark for the one-year period that ended June 30, 2026. The Bloomberg Municipal Bond Index delivered a 7.03% total return over the trailing year, supported by a powerful Federal Reserve rate cut rally in late summer 2025, and partially offset by a selloff in March 2026, reflecting concerns around inflation, oil prices, and fallout from the Iran war before recovering. A key story in the municipal market was the record supply of new issuance. However, demand from individual investors remained strong as municipal fund flows were fairly steady. The main contributors to Fund performance during the period were duration positioning; our credit allocation – particularly in BBB- and BB-rated names; and allocation to the education and electric sectors. In contrast, weak security selection in the lease sector offset some of these gains. We believe that an active approach will continue to benefit shareholders as the potential for further market volatility remains and thoughtful positioning of portfolios can help navigate uncertain markets.

Factors Affecting Performance [Text Block]

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

The Fund outperformed its benchmark for the one-year period that ended June 30, 2026. The Bloomberg Municipal Bond Index delivered a 7.03% total return over the trailing year, supported by a powerful Federal Reserve rate cut rally in late summer 2025, and partially offset by a selloff in March 2026, which was reflecting concerns around inflation, oil prices, and fallout from the Iran war before recovering. A key story in the municipal bond market was the record supply of new issuance. However, demand from individual investors remained strong as municipal fund flows were fairly steady. Top contributors to Fund performance during the period were duration position, as well as sector allocation and security selection, particularly in the transportation, industrial development revenue/pollution control revenue (IDR/PCR), and hospital sectors. We believe that an active approach will continue to benefit shareholders as the potential for further market volatility remains and thoughtful positioning of portfolios can help navigate uncertain markets.

Factors Affecting Performance [Text Block]

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

The Fund outperformed its benchmark for the one-year period that ended June 30, 2026. The Bloomberg Municipal Bond Index delivered a 7.03% total return over the trailing year, supported by a powerful Federal Reserve rate cut rally in late summer 2025, and partially offset by a selloff in March 2026, reflecting concerns around inflation, oil prices, and fallout from the Iran war before recovering. A key story in the municipal bond market was the record supply of new issuance. However, demand from individual investors remained strong as municipal fund flows were fairly steady. Top contributors to Fund performance during the period were duration positioning, credit allocation, particularly in AA- and BB-rated names, as well as allocation to the hospital and electric sectors, while security selection in the housing sector offset some of these gains. We believe that an active approach will continue to benefit shareholders as the potential for further market volatility remains and thoughtful positioning of portfolios can help navigate uncertain markets.

Factors Affecting Performance [Text Block]

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

The Fund outperformed its benchmark for the one-year period that ended June 30, 2026. The Bloomberg Municipal Bond Index delivered a 7.03% total return over the trailing year, supported by a powerful Federal Reserve rate cut rally in late summer 2025, and partially offset by a selloff in March 2026, reflecting concerns around inflation, oil prices, and fallout from the Iran war before recovering. A key story in the municipal bond market was the record supply of new issuance. However, demand from individual investors remained strong as municipal fund flows were fairly steady. Top contributors to Fund performance during the period were duration positioning, credit allocation, particularly in AA- and BB-rated names, as well as allocation to the hospital and electric sectors, while security selection in the housing sector offset some of these gains. We believe that an active approach will continue to benefit shareholders as the potential for further market volatility remains and thoughtful positioning of portfolios can help navigate uncertain markets.

Factors Affecting Performance [Text Block]

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

The Fund outperformed its benchmark for the one-year period that ended June 30, 2026. The Bloomberg Municipal Bond Index delivered a 7.03% total return over the trailing year, supported by a powerful Federal Reserve rate cut rally in late summer 2025, and partially offset by a selloff in March 2026, reflecting concerns around inflation, oil prices, and fallout from the Iran war before recovering. A key story in the municipal bond market was the record supply of new issuance. However, demand from individual investors remained strong as municipal fund flows were fairly steady. Top contributors to Fund performance during the period were duration positioning, credit allocation, particularly in AA- and BB-rated names, as well as allocation to the hospital and electric sectors, while security selection in the housing sector offset some of these gains. We believe that an active approach will continue to benefit shareholders as the potential for further market volatility remains and thoughtful positioning of portfolios can help navigate uncertain markets.

Factors Affecting Performance [Text Block]

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

The Fund outperformed its benchmark for the one-year period that ended June 30, 2026. The Bloomberg Municipal Bond Index returned 7.03% over the trailing year, supported by a powerful Federal Reserve rate cut rally in late summer 2025, and partially offset by a selloff in March 2026, reflecting concerns around inflation, oil prices, and fallout from the Iran war before recovering. A key story in the municipal bond market was the record supply of new issuance. However, demand from individual investors remained strong as municipal fund flows were fairly steady. Top contributors to Fund performance were duration and credit positioning, particularly AAA-rated and below investment grade issues, as well as allocation to the water and sewer, and general obligation sectors. The gains were partially offset by security selection decisions within the industrial development revenue/pollution control revenue (IDR/PCR) and transportation sectors. We believe that an active approach will continue to benefit shareholders as the potential for further market volatility remains and thoughtful positioning of portfolios can help navigate uncertain markets.

Factors Affecting Performance [Text Block]

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

The Fund underperformed its benchmark for the one-year period that ended June 30, 2026. The Bloomberg Municipal Bond Index delivered a 7.03% total return over the trailing year, supported by a powerful Federal Reserve rate cut rally in late summer 2025, and partially offset by a selloff in March 2026, reflecting concerns around inflation, oil prices, and fallout from the Iran war before recovering. A key story in the municipal bond market throughout the period was the record supply of new issuance. However, demand from individual investors remained strong as municipal fund flows were fairly steady. The main detractor from relative performance was security selection, particularly in the housing sector, while our allocation to the electric and special tax sectors offset some losses. We believe that an active approach will continue to benefit shareholders as the potential for further market volatility remains and thoughtful positioning of portfolios can help navigate uncertain markets.

Factors Affecting Performance [Text Block]

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

The Fund underperformed its benchmark for the one-year period that ended June 30, 2026. The Bloomberg Municipal Bond Index delivered a 7.03% total return over the trailing year, supported by a powerful Federal Reserve rate cut rally in late summer 2025, and partially offset by a selloff in March 2026, reflecting concerns around inflation, oil prices, and fallout from the Iran war before recovering. A key story in the municipal bond market throughout the period was the record supply of new issuance. However, demand from individual investors remained strong as municipal fund flows were fairly steady. The main detractor from relative performance was security selection, particularly in the housing sector, while our allocation to the electric and special tax sectors offset some losses. We believe that an active approach will continue to benefit shareholders as the potential for further market volatility remains and thoughtful positioning of portfolios can help navigate uncertain markets.

Factors Affecting Performance [Text Block]

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

The Fund underperformed its benchmark for the one-year period that ended June 30, 2026. The Bloomberg Municipal Bond Index delivered a 7.03% total return over the trailing year, supported by a powerful Federal Reserve rate cut rally in late summer 2025, and partially offset by a selloff in March 2026, reflecting concerns around inflation, oil prices, and fallout from the Iran war before recovering. A key story in the municipal bond market throughout the period was the record supply of new issuance. However, demand from individual investors remained strong as municipal fund flows were fairly steady. The main detractor from relative performance was security selection, particularly in the housing sector, while our allocation to the electric and special tax sectors offset some losses. We believe that an active approach will continue to benefit shareholders as the potential for further market volatility remains and thoughtful positioning of portfolios can help navigate uncertain markets.

Factors Affecting Performance [Text Block]

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

The Fund underperformed its benchmark for the one-year period that ended June 30, 2026. The Bloomberg Municipal Bond Index delivered a 7.03% total return over the trailing year, supported by a powerful Federal Reserve rate cut rally in late summer 2025, and partially offset by a selloff in March 2026, reflecting concerns around inflation, oil prices, and fallout from the Iran war before recovering. A key story in the municipal bond market was the record supply of new issuance. However, demand from individual investors remained strong as municipal fund flows were fairly steady. Top contributors to Fund performance during the period were duration and credit positioning, particularly BBB- and BB-rated names, as well as allocation to the industrial development revenue/pollution control revenue (IDR/PCR) and general obligation sectors, while security selection within the housing sector offset some gains. We believe that an active approach will continue to benefit shareholders as the potential for further market volatility remains and thoughtful positioning of portfolios can help navigate uncertain markets.

Factors Affecting Performance [Text Block]

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

The Fund underperformed its benchmark for the one-year period that ended June 30, 2026. The Bloomberg Municipal Bond Index delivered a 7.03% total return over the trailing year, supported by a powerful Federal Reserve rate cut rally in late summer 2025, and partially offset by a selloff in March 2026, reflecting concerns around inflation, oil prices, and fallout from the Iran war before recovering. A key story in the municipal bond market was the record supply of new issuance. However, demand from individual investors remained strong as municipal fund flows were fairly steady. Top contributors to Fund performance during the period were duration and credit positioning, particularly BBB- and BB-rated names, as well as allocation to the industrial development revenue/pollution control revenue (IDR/PCR) and general obligation sectors, while security selection within the housing sector offset some gains. We believe that an active approach will continue to benefit shareholders as the potential for further market volatility remains and thoughtful positioning of portfolios can help navigate uncertain markets.

Factors Affecting Performance [Text Block]

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

The Fund outperformed its benchmark for the one-year period that ended June 30, 2026. The Bloomberg Municipal Bond Index delivered a 7.03% total return over the trailing year, supported by a powerful Federal Reserve rate cut rally in late summer 2025, and partially offset by a selloff in March 2026, reflecting concerns around inflation, oil prices, and fallout from the Iran war before recovering. A key story in the municipal bond market throughout the period was the record supply of new issuance. However, demand from individual investors remained strong as municipal fund flows were fairly steady.Top contributors to Fund performance during the period were duration, credit allocation, particularly to AAA- and AA-rated names, as well as allocation to the general obligation, electric, and hospital sectors while security selection in the housing sector detracted. We believe that an active approach will continue to benefit shareholders as the potential for further market volatility remains and thoughtful positioning of portfolios can help navigate uncertain markets.

Factors Affecting Performance [Text Block]

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

The Fund outperformed its benchmark for the one-year period that ended June 30, 2026. The Bloomberg Municipal Bond Index delivered a 7.03% total return over the trailing year, supported by a powerful Federal Reserve rate cut rally in late summer 2025, and partially offset by a selloff in March 2026, reflecting concerns around inflation, oil prices, and fallout from the Iran war before recovering. A key story in the municipal bond market throughout the period was the record supply of new issuance. However, demand from individual investors remained strong as municipal fund flows were fairly steady.Top contributors to Fund performance during the period were duration, credit allocation, particularly to AAA- and AA-rated names, as well as allocation to the general obligation, electric, and hospital sectors while security selection in the housing sector detracted. We believe that an active approach will continue to benefit shareholders as the potential for further market volatility remains and thoughtful positioning of portfolios can help navigate uncertain markets.

Factors Affecting Performance [Text Block]

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

The Fund outperformed its benchmark for the one-year period that ended June 30, 2026. The Bloomberg Municipal Bond Index delivered a 7.03% total return over the trailing year, supported by a powerful Federal Reserve rate cut rally in late summer 2025, and partially offset by a selloff in March 2026, reflecting concerns around inflation, oil prices, and fallout from the Iran war before recovering. A key story in the municipal bond market throughout the period was the record supply of new issuance. However, demand from individual investors remained strong as municipal fund flows were fairly steady.Top contributors to Fund performance during the period were duration, credit allocation, particularly to AAA- and AA-rated names, as well as allocation to the general obligation, electric, and hospital sectors while security selection in the housing sector detracted. We believe that an active approach will continue to benefit shareholders as the potential for further market volatility remains and thoughtful positioning of portfolios can help navigate uncertain markets.

Factors Affecting Performance [Text Block]

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

The Fund outperformed its benchmark for the one-year period that ended June 30, 2026. The Bloomberg Municipal Bond Index delivered a 7.03% total return over the trailing year, supported by a powerful Federal Reserve rate cut rally in late summer 2025, and partially offset by a selloff in March 2026, reflecting concerns around inflation, oil prices, and fallout from the Iran war before recovering. A key story in the municipal bond market throughout the period was the record supply of new issuance. However, demand from individual investors remained strong as municipal fund flows were fairly steady.Top contributors to Fund performance were duration and credit positioning, particularly in A- and AA-rated names, as well as allocation within the education, general obligation, and transportation sectors. We believe that an active approach will continue to benefit shareholders as the potential for further market volatility remains and thoughtful positioning of portfolios can help navigate uncertain markets.

Factors Affecting Performance [Text Block]

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

The Fund outperformed its benchmark for the one-year period that ended June 30, 2026. The Bloomberg Municipal Bond Index delivered a 7.03% total return over the trailing year, supported by a powerful Federal Reserve rate cut rally in late summer 2025, and partially offset by a selloff in March 2026, reflecting concerns around inflation, oil prices, and fallout from the Iran war before recovering. A key story in the municipal bond market throughout the period was the record supply of new issuance. However, demand from individual investors remained strong as municipal fund flows were fairly steady.Top contributors to Fund performance were duration and credit positioning, particularly in A- and AA-rated names, as well as allocation within the education, general obligation, and transportation sectors. We believe that an active approach will continue to benefit shareholders as the potential for further market volatility remains and thoughtful positioning of portfolios can help navigate uncertain markets.

The Bloomberg Municipal Bond Index delivered a 7.03% total return over the trailing year, supported by a powerful Federal Reserve rate cut rally in late summer 2025, and partially offset by a selloff in March 2026, reflecting concerns around inflation, oil prices, and fallout from the Iran war before recovering. A key story in the municipal bond market throughout the period was the record supply of new issuance. However, demand from individual investors remained strong as municipal fund flows were fairly steady.Top contributors to Fund performance were duration and credit positioning, particularly in A- and AA-rated names, as well as allocation within the education, general obligation, and transportation sectors. We believe that an active approach will continue to benefit shareholders as the potential for further market volatility remains and thoughtful positioning of portfolios can help navigate uncertain markets.

Factors Affecting Performance [Text Block]

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

Top contributors to Fund performance were duration and credit positioning, particularly AAA- and AA-rated names, as well as allocation within the general obligation, hospital, and electric sectors, while security selection within the housing sector offset some gains. We believe that an active approach will continue to benefit shareholders as the potential for further market volatility remains and thoughtful positioning of portfolios can help navigate uncertain markets.

Factors Affecting Performance [Text Block]

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

The Fund underperformed its benchmark for the one-year period that ended June 30, 2026. The Bloomberg Municipal Bond Index delivered a 7.03% total return over the trailing year, supported by a powerful Federal Reserve rate cut rally in late summer 2025, and partially offset by a selloff in March 2026, reflecting concerns around inflation, oil prices, and fallout from the Iran war before recovering. A key story in the municipal bond market throughout the period was the record supply of new issuance. However, demand from individual investors remained strong as municipal fund flows were fairly steady. The main detractors from Fund relative performance were duration positioning and security selection, particularly in the industrial development revenue/pollution control revenue (IDR/PCR) and transportation sectors, while our credit allocation to AA- and AAA-rated issues and allocation to the education sector offset some losses. We believe that an active approach will continue to benefit shareholders as the potential for further market volatility remains and thoughtful positioning of portfolios can help navigate uncertain markets.

Factors Affecting Performance [Text Block]

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

The Fund underperformed its benchmark for the one-year period that ended June 30, 2026. The Bloomberg Municipal Bond Index delivered a 7.03% total return over the trailing year, supported by a powerful Federal Reserve rate cut rally in late summer 2025, and partially offset by a selloff in March 2026, reflecting concerns around inflation, oil prices, and fallout from the Iran war before recovering. A key story in the municipal bond market throughout the period was the record supply of new issuance. However, demand from individual investors remained strong as municipal fund flows were fairly steady. The main detractors from Fund relative performance were duration positioning and security selection, particularly in the industrial development revenue/pollution control revenue (IDR/PCR) and transportation sectors, while our credit allocation to AA- and AAA-rated issues and allocation to the education sector offset some losses. We believe that an active approach will continue to benefit shareholders as the potential for further market volatility remains and thoughtful positioning of portfolios can help navigate uncertain markets.
