US Federal Reserve (Fed) cuts in 4Q25 and legislative clarity contributed to performance. However, the US-Iran conflict and subsequent inflation concerns applied pressure to the market. Additionally, market technicals impacted performance.&lt;/div&gt;  &lt;div style="margin-top: 0px; font-size: 10pt; font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); margin-bottom: 0px; margin-left: 26pt;"&gt;Supply was elevated but met with strong demand as municipal mutual funds took in a near record amount in the first eight months of 2026. More importantly, the flows were evenly distributed between open-ended funds and exchange-traded funds (ETFs) in calendar year 2026.&lt;/div&gt;  &lt;div style="margin-top: 0px; font-size: 10pt; font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); margin-bottom: 0px; margin-left: 26pt;"&gt;Municipal bond yields rose on the front end of the curve and fell in the intermediate and long segments. For example, the MMD AAA 2-year yield rose 33 basis points (bps) while the 20-year yield fell 15 bps and the 30-year yield fell 1 bp (a basis point equals one-hundredth of a percentage point). As a result, the 2-year/30-year curve flattened, starting the period at 241 bps and ending the period at 207 bps.&lt;/div&gt;  &lt;div style="margin-top: 0px; font-size: 10pt; font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); margin-bottom: 0px; margin-left: 26pt;"&gt;The long end of the curve outperformed as did lower investment grade BBB-rated and below-investment-grade securities during the reporting period, in part, driven by the strong fund flows into long mutual funds. For example, the Bloomberg Municipal Bond Index returned 4.12% while the long segment (22+ years) returned 6.45%; BBB-rated and below&#x2011;investment&#x2011;grade securities returned 6.08% and 6.66%, respectively. Conversely, the front end of the curve detracted from performance for the period with the Bloomberg Municipal Bond Index&#x2019;s 1-year (1-2 years) segment only up 2.36%.&lt;/div&gt;  &lt;div style="font-family: 'arial'; font-size: 10pt; margin-bottom: 3pt; margin-top: 15pt; color: rgb(0, 0, 0); text-transform: none; letter-spacing: normal; font-weight: bold;"&gt;Top contributors to performance:&lt;/div&gt;  &lt;div style="margin-top: 0px; font-size: 10pt; font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); margin-bottom: 0px; margin-left: 26pt;"&gt;An overweight to the long end of the curve contributed to performance.&lt;/div&gt;  &lt;div style="margin-top: 0px; font-size: 10pt; font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); margin-bottom: 0px; margin-left: 26pt;"&gt;An overweight to BBB-rated securities, in addition to a full out-of-benchmark allocation to below-investment-grade bonds, also contributed.&lt;/div&gt;  &lt;div style="font-family: 'arial'; font-size: 10pt; margin-bottom: 3pt; margin-top: 15pt; color: rgb(0, 0, 0); text-transform: none; letter-spacing: normal; font-weight: bold;"&gt;Top detractors from performance:&lt;/div&gt;  &lt;div style="margin-top: 0px; font-size: 10pt; font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); margin-bottom: 0px; margin-left: 26pt;"&gt;A modest out-of-benchmark allocation to the front end of the curve (0-1 years) was a drag on performance as this part of the curve lagged the overall market.&lt;/div&gt;  &lt;div style="margin-top: 0px; font-size: 10pt; font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); margin-bottom: 0px; margin-left: 26pt;"&gt;The transportation sector was a detractor, underperforming the benchmark&#x2019;s transportation return of 4.86%.&lt;/div&gt; </oef:FactorsAffectingPerfTextBlock>

US Federal Reserve (Fed) cuts in 4Q25 and legislative clarity contributed to performance. However, the US-Iran conflict and subsequent inflation concerns applied pressure to the market. Additionally, market technicals impacted performance.&lt;/div&gt;  &lt;div style="margin-top: 0px; font-size: 10pt; font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); margin-bottom: 0px; margin-left: 26pt;"&gt;Supply was elevated but met with strong demand as municipal mutual funds took in a near record amount in the first eight months of 2026. More importantly, the flows were evenly distributed between open-ended funds and exchange-traded funds (ETFs) in calendar year 2026.&lt;/div&gt;  &lt;div style="margin-top: 0px; font-size: 10pt; font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); margin-bottom: 0px; margin-left: 26pt;"&gt;Municipal bond yields rose on the front end of the curve and fell in the intermediate and long segments. For example, the MMD AAA 2-year yield rose 33 basis points (bps) while the 20-year yield fell 15 bps and the 30-year yield fell 1 bp (a basis point equals one-hundredth of a percentage point). As a result, the 2-year/30-year curve flattened, starting the period at 241 bps and ending the period at 207 bps.&lt;/div&gt;  &lt;div style="margin-top: 0px; font-size: 10pt; font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); margin-bottom: 0px; margin-left: 26pt;"&gt;The long end of the curve outperformed as did lower investment grade BBB-rated and below-investment-grade securities during the reporting period, in part, driven by the strong fund flows into long mutual funds. For example, the Bloomberg Municipal Bond Index returned 4.12% while the long segment (22+ years) returned 6.45%; BBB-rated and below&#x2011;investment&#x2011;grade securities returned 6.08% and 6.66%, respectively. Conversely, the front end of the curve detracted from performance for the period with the Bloomberg Municipal Bond Index&#x2019;s 1-year (1-2 years) segment only up 2.36%.&lt;/div&gt;  &lt;div style="font-family: 'arial'; font-size: 10pt; margin-bottom: 3pt; margin-top: 15pt; color: rgb(0, 0, 0); text-transform: none; letter-spacing: normal; font-weight: bold;"&gt;Top contributors to performance:&lt;/div&gt;  &lt;div style="margin-top: 0px; font-size: 10pt; font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); margin-bottom: 0px; margin-left: 26pt;"&gt;An overweight to the long end of the curve contributed to performance.&lt;/div&gt;  &lt;div style="margin-top: 0px; font-size: 10pt; font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); margin-bottom: 0px; margin-left: 26pt;"&gt;An overweight to BBB-rated securities, in addition to a full out-of-benchmark allocation to below-investment-grade bonds, also contributed.&lt;/div&gt;  &lt;div style="font-family: 'arial'; font-size: 10pt; margin-bottom: 3pt; margin-top: 15pt; color: rgb(0, 0, 0); text-transform: none; letter-spacing: normal; font-weight: bold;"&gt;Top detractors from performance:&lt;/div&gt;  &lt;div style="margin-top: 0px; font-size: 10pt; font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); margin-bottom: 0px; margin-left: 26pt;"&gt;A modest out-of-benchmark allocation to the front end of the curve (0-1 years) was a drag on performance as this part of the curve lagged the overall market.&lt;/div&gt;  &lt;div style="margin-top: 0px; font-size: 10pt; font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); margin-bottom: 0px; margin-left: 26pt;"&gt;The transportation sector was a detractor, underperforming the benchmark&#x2019;s transportation return of 4.86%.&lt;/div&gt; </oef:FactorsAffectingPerfTextBlock>

US Federal Reserve (Fed) cuts in 4Q25 and legislative clarity contributed to performance. However, the US-Iran conflict and subsequent inflation concerns applied pressure to the market. Additionally, market technicals impacted performance.&lt;/div&gt;  &lt;div style="margin-top: 0px; font-size: 10pt; font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); margin-bottom: 0px; margin-left: 26pt;"&gt;Supply was elevated but met with strong demand as municipal mutual funds took in a near record amount in the first eight months of 2026. More importantly, the flows were evenly distributed between open-ended funds and exchange-traded funds (ETFs) in calendar year 2026.&lt;/div&gt;  &lt;div style="margin-top: 0px; font-size: 10pt; font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); margin-bottom: 0px; margin-left: 26pt;"&gt;Municipal bond yields rose on the front end of the curve and fell in the intermediate and long segments. For example, the MMD AAA 2-year yield rose 33 basis points (bps) while the 20-year yield fell 15 bps and the 30-year yield fell 1 bp (a basis point equals one-hundredth of a percentage point). As a result, the 2-year/30-year curve flattened, starting the period at 241 bps and ending the period at 207 bps.&lt;/div&gt;  &lt;div style="margin-top: 0px; font-size: 10pt; font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); margin-bottom: 0px; margin-left: 26pt;"&gt;The long end of the curve outperformed as did lower investment grade BBB-rated and below-investment-grade securities during the reporting period, in part, driven by the strong fund flows into long mutual funds. For example, the Bloomberg Municipal Bond Index returned 4.12% while the long segment (22+ years) returned 6.45%; BBB-rated and below&#x2011;investment&#x2011;grade securities returned 6.08% and 6.66%, respectively. Conversely, the front end of the curve detracted from performance for the period with the Bloomberg Municipal Bond Index&#x2019;s 1-year (1-2 years) segment only up 2.36%.&lt;/div&gt;  &lt;div style="font-family: 'arial'; font-size: 10pt; margin-bottom: 3pt; margin-top: 15pt; color: rgb(0, 0, 0); text-transform: none; letter-spacing: normal; font-weight: bold;"&gt;Top contributors to performance:&lt;/div&gt;  &lt;div style="margin-top: 0px; font-size: 10pt; font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); margin-bottom: 0px; margin-left: 26pt;"&gt;An overweight to the long end of the curve contributed to performance.&lt;/div&gt;  &lt;div style="margin-top: 0px; font-size: 10pt; font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); margin-bottom: 0px; margin-left: 26pt;"&gt;An overweight to BBB-rated securities, in addition to a full out-of-benchmark allocation to below-investment-grade bonds, also contributed.&lt;/div&gt;  &lt;div style="font-family: 'arial'; font-size: 10pt; margin-bottom: 3pt; margin-top: 15pt; color: rgb(0, 0, 0); text-transform: none; letter-spacing: normal; font-weight: bold;"&gt;Top detractors from performance:&lt;/div&gt;  &lt;div style="margin-top: 0px; font-size: 10pt; font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); margin-bottom: 0px; margin-left: 26pt;"&gt;A modest out-of-benchmark allocation to the front end of the curve (0-1 years) was a drag on performance as this part of the curve lagged the overall market.&lt;/div&gt;  &lt;div style="margin-top: 0px; font-size: 10pt; font-weight: 400; font-family: 'arial'; color: rgb(0, 0, 0); margin-bottom: 0px; margin-left: 26pt;"&gt;The transportation sector was a detractor, underperforming the benchmark&#x2019;s transportation return of 4.86%.&lt;/div&gt; </oef:FactorsAffectingPerfTextBlock>

US Federal Reserve (Fed) cuts in 4Q25 and legislative clarity contributed to performance. However, the US-Iran conflict and subsequent inflation concerns applied pressure to the market. Additionally, market technicals impacted performance.&lt;/div&gt;  &lt;div style="margin-top: 0px; font-size: 10pt; font-weight: 400; line-height: 115%; font-family: 'arial'; color: rgb(0, 0, 0); margin-bottom: 0px; margin-left: 26pt;"&gt;Supply was elevated but met with strong demand as municipal mutual funds took in a near record amount in the first eight months of 2026. More importantly, the flows were evenly distributed between open-ended funds and exchange-traded funds (ETFs) in calendar year 2026.&lt;/div&gt;  &lt;div style="margin-top: 0px; font-size: 10pt; font-weight: 400; line-height: 115%; font-family: 'arial'; color: rgb(0, 0, 0); margin-bottom: 0px; margin-left: 26pt;"&gt;Municipal bond yields rose on the front end of the curve and fell in the intermediate and long segments. For example, the MMD AAA 2-year yield rose 33 basis points (bps) while the 20-year yield fell 15 bps and the 30-year yield fell 1 bp (a basis point equals one-hundredth of a percentage point). As a result, the 2-year/30-year curve flattened, starting the period at 241 bps and ending the period at 207 bps.&lt;/div&gt;  &lt;div style="margin-top: 0px; font-size: 10pt; font-weight: 400; line-height: 115%; font-family: 'arial'; color: rgb(0, 0, 0); margin-bottom: 0px; margin-left: 26pt;"&gt;The long end of the curve outperformed as did lower investment grade BBB-rated and below-investment-grade securities during the reporting period, in part, driven by the strong fund flows into long mutual funds. For example, the Bloomberg Municipal Bond Index returned 4.12% while the long segment (22+ years) returned 6.45%; BBB-rated and below-investment-grade securities returned 6.08% and 6.66%, respectively. Conversely, the front end of the curve detracted from performance for the period with the Bloomberg Municipal Bond Index&#x2019;s 1-year (1-2 years) segment only up 2.36%.&lt;/div&gt;  &lt;div style="font-family: 'arial'; font-size: 10pt; line-height: 115%; margin-bottom: 3pt; margin-top: 15pt; color: rgb(0, 0, 0); text-transform: none; letter-spacing: normal; font-weight: bold;"&gt;Top contributors to performance:&lt;/div&gt;  &lt;div style="margin-top: 0px; font-size: 10pt; font-weight: 400; line-height: 115%; font-family: 'arial'; color: rgb(0, 0, 0); margin-bottom: 0px; margin-left: 26pt;"&gt;An out-of-benchmark allocation to the long end of the curve contributed to performance.&lt;/div&gt;  &lt;div style="margin-top: 0px; font-size: 10pt; font-weight: 400; line-height: 115%; font-family: 'arial'; color: rgb(0, 0, 0); margin-bottom: 0px; margin-left: 26pt;"&gt;An overweight to BBB-rated securities contributed to performance for the period.&lt;/div&gt;  &lt;div style="font-family: 'arial'; font-size: 10pt; line-height: 115%; margin-bottom: 3pt; margin-top: 15pt; color: rgb(0, 0, 0); text-transform: none; letter-spacing: normal; font-weight: bold;"&gt;Top detractors from performance:&lt;/div&gt;  &lt;div style="margin-top: 0px; font-size: 10pt; font-weight: 400; line-height: 115%; font-family: 'arial'; color: rgb(0, 0, 0); margin-bottom: 0px; margin-left: 26pt;"&gt;A modest out-of-benchmark allocation to the front end of the curve (0-2 years) was a drag on performance as this part of the curve lagged the overall market.&lt;/div&gt;  &lt;div style="margin-top: 0px; font-size: 10pt; font-weight: 400; line-height: 115%; font-family: 'arial'; color: rgb(0, 0, 0); margin-bottom: 0px; margin-left: 26pt;"&gt;The Industrial Development Revenue (IDR)/Pollution Control Revenue (PCR) sector was a detractor for the period.

US Federal Reserve (Fed) cuts in 4Q25 and legislative clarity contributed to performance. However, the US-Iran conflict and subsequent inflation concerns applied pressure to the market. Additionally, market technicals impacted performance.&lt;/div&gt;  &lt;div style="margin-top: 0px; font-size: 10pt; font-weight: 400; line-height: 115%; font-family: 'arial'; color: rgb(0, 0, 0); margin-bottom: 0px; margin-left: 26pt;"&gt;Supply was elevated but met with strong demand as municipal mutual funds took in a near record amount in the first eight months of 2026. More importantly, the flows were evenly distributed between open-ended funds and exchange-traded funds (ETFs) in calendar year 2026.&lt;/div&gt;  &lt;div style="margin-top: 0px; font-size: 10pt; font-weight: 400; line-height: 115%; font-family: 'arial'; color: rgb(0, 0, 0); margin-bottom: 0px; margin-left: 26pt;"&gt;Municipal bond yields rose on the front end of the curve and fell in the intermediate and long segments. For example, the MMD AAA 2-year yield rose 33 basis points (bps) while the 20-year yield fell 15 bps and the 30-year yield fell 1 bp (a basis point equals one-hundredth of a percentage point). As a result, the 2-year/30-year curve flattened, starting the period at 241 bps and ending the period at 207 bps.&lt;/div&gt;  &lt;div style="margin-top: 0px; font-size: 10pt; font-weight: 400; line-height: 115%; font-family: 'arial'; color: rgb(0, 0, 0); margin-bottom: 0px; margin-left: 26pt;"&gt;The long end of the curve outperformed as did lower investment grade BBB-rated and below-investment-grade securities during the reporting period, in part, driven by the strong fund flows into long mutual funds. For example, the Bloomberg Municipal Bond Index returned 4.12% while the long segment (22+ years) returned 6.45%; BBB-rated and below-investment-grade securities returned 6.08% and 6.66%, respectively. Conversely, the front end of the curve detracted from performance for the period with the Bloomberg Municipal Bond Index&#x2019;s 1-year (1-2 years) segment only up 2.36%.&lt;/div&gt;  &lt;div style="font-family: 'arial'; font-size: 10pt; line-height: 115%; margin-bottom: 3pt; margin-top: 15pt; color: rgb(0, 0, 0); text-transform: none; letter-spacing: normal; font-weight: bold;"&gt;Top contributors to performance:&lt;/div&gt;  &lt;div style="margin-top: 0px; font-size: 10pt; font-weight: 400; line-height: 115%; font-family: 'arial'; color: rgb(0, 0, 0); margin-bottom: 0px; margin-left: 26pt;"&gt;An out-of-benchmark allocation to the long end of the curve contributed to performance.&lt;/div&gt;  &lt;div style="margin-top: 0px; font-size: 10pt; font-weight: 400; line-height: 115%; font-family: 'arial'; color: rgb(0, 0, 0); margin-bottom: 0px; margin-left: 26pt;"&gt;An overweight to BBB-rated securities contributed to performance for the period.&lt;/div&gt;  &lt;div style="font-family: 'arial'; font-size: 10pt; line-height: 115%; margin-bottom: 3pt; margin-top: 15pt; color: rgb(0, 0, 0); text-transform: none; letter-spacing: normal; font-weight: bold;"&gt;Top detractors from performance:&lt;/div&gt;  &lt;div style="margin-top: 0px; font-size: 10pt; font-weight: 400; line-height: 115%; font-family: 'arial'; color: rgb(0, 0, 0); margin-bottom: 0px; margin-left: 26pt;"&gt;A modest out-of-benchmark allocation to the front end of the curve (0-2 years) was a drag on performance as this part of the curve lagged the overall market.&lt;/div&gt;  &lt;div style="margin-top: 0px; font-size: 10pt; font-weight: 400; line-height: 115%; font-family: 'arial'; color: rgb(0, 0, 0); margin-bottom: 0px; margin-left: 26pt;"&gt;The Industrial Development Revenue (IDR)/Pollution Control Revenue (PCR) sector was a detractor for the period.

US Federal Reserve (Fed) cuts in 4Q25 and legislative clarity contributed to performance. However, the US-Iran conflict and subsequent inflation concerns applied pressure to the market. Additionally, market technicals impacted performance.&lt;/div&gt;  &lt;div style="margin-top: 0px; font-size: 10pt; font-weight: 400; line-height: 115%; font-family: 'arial'; color: rgb(0, 0, 0); margin-bottom: 0px; margin-left: 26pt;"&gt;Supply was elevated but met with strong demand as municipal mutual funds took in a near record amount in the first eight months of 2026. More importantly, the flows were evenly distributed between open-ended funds and exchange-traded funds (ETFs) in calendar year 2026.&lt;/div&gt;  &lt;div style="margin-top: 0px; font-size: 10pt; font-weight: 400; line-height: 115%; font-family: 'arial'; color: rgb(0, 0, 0); margin-bottom: 0px; margin-left: 26pt;"&gt;Municipal bond yields rose on the front end of the curve and fell in the intermediate and long segments. For example, the MMD AAA 2-year yield rose 33 basis points (bps) while the 20-year yield fell 15 bps and the 30-year yield fell 1 bp (a basis point equals one-hundredth of a percentage point). As a result, the 2-year/30-year curve flattened, starting the period at 241 bps and ending the period at 207 bps.&lt;/div&gt;  &lt;div style="margin-top: 0px; font-size: 10pt; font-weight: 400; line-height: 115%; font-family: 'arial'; color: rgb(0, 0, 0); margin-bottom: 0px; margin-left: 26pt;"&gt;The long end of the curve outperformed as did lower investment grade BBB-rated and below-investment-grade securities during the reporting period, in part, driven by the strong fund flows into long mutual funds. For example, the Bloomberg Municipal Bond Index returned 4.12% while the long segment (22+ years) returned 6.45%; BBB-rated and below-investment-grade securities returned 6.08% and 6.66%, respectively. Conversely, the front end of the curve detracted from performance for the period with the Bloomberg Municipal Bond Index&#x2019;s 1-year (1-2 years) segment only up 2.36%.&lt;/div&gt;  &lt;div style="font-family: 'arial'; font-size: 10pt; line-height: 115%; margin-bottom: 3pt; margin-top: 15pt; color: rgb(0, 0, 0); text-transform: none; letter-spacing: normal; font-weight: bold;"&gt;Top contributors to performance:&lt;/div&gt;  &lt;div style="margin-top: 0px; font-size: 10pt; font-weight: 400; line-height: 115%; font-family: 'arial'; color: rgb(0, 0, 0); margin-bottom: 0px; margin-left: 26pt;"&gt;An out-of-benchmark allocation to the long end of the curve contributed to performance.&lt;/div&gt;  &lt;div style="margin-top: 0px; font-size: 10pt; font-weight: 400; line-height: 115%; font-family: 'arial'; color: rgb(0, 0, 0); margin-bottom: 0px; margin-left: 26pt;"&gt;An overweight to BBB-rated securities contributed to performance for the period.&lt;/div&gt;  &lt;div style="font-family: 'arial'; font-size: 10pt; line-height: 115%; margin-bottom: 3pt; margin-top: 15pt; color: rgb(0, 0, 0); text-transform: none; letter-spacing: normal; font-weight: bold;"&gt;Top detractors from performance:&lt;/div&gt;  &lt;div style="margin-top: 0px; font-size: 10pt; font-weight: 400; line-height: 115%; font-family: 'arial'; color: rgb(0, 0, 0); margin-bottom: 0px; margin-left: 26pt;"&gt;A modest out-of-benchmark allocation to the front end of the curve (0-2 years) was a drag on performance as this part of the curve lagged the overall market.&lt;/div&gt;  &lt;div style="margin-top: 0px; font-size: 10pt; font-weight: 400; line-height: 115%; font-family: 'arial'; color: rgb(0, 0, 0); margin-bottom: 0px; margin-left: 26pt;"&gt;The Industrial Development Revenue (IDR)/Pollution Control Revenue (PCR) sector was a detractor for the period.
