US Federal Reserve (Fed) cuts in 4Q25 and legislative clarity contributed to performance. However, the US&#x2011;Iran conflict and subsequent inflation concerns applied pressure to the market. Additionally, market technicals impacted performance.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt;

More importantly, the flows were evenly distributed between open-ended funds and exchange-traded funds (ETFs) in calendar year 2026.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt;

For example, the MMD AAA 2&#x2011;year yield rose 33 basis points (bps) while the 20&#x2011;year yield fell 15 bps and the 30&#x2011;year yield fell 1 bp (a basis point equals one&#x2011;hundredth of a percentage point). As a result, the 2&#x2011;year/30&#x2011;year curve flattened, starting the period at 241 bps and ending the period at 207 bps.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt;

For example, the Bloomberg Municipal Bond Index returned 4.12% while the long segment (22+ years) returned 6.45%; BBB&#x2011;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&#x2011;year (1&#x2011;2 years) segment only up 2.36%.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt;&lt;div style="margin-top: 12pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial; font-weight: bold;"&gt;Top contributors to performance:&lt;/div&gt;

US Federal Reserve (Fed) cuts in 4Q25 and legislative clarity contributed to performance. However, the US&#x2011;Iran conflict and subsequent inflation concerns applied pressure to the market.

For example, the MMD AAA 2&#x2011;year yield rose 33 basis points (bps) while the 20&#x2011;year yield fell 15 bps and the 30&#x2011;year yield fell 1 bp (a basis point equals one&#x2011;hundredth of a percentage point). As a result, the 2&#x2011;year/30&#x2011;year curve flattened, starting the period at 241 bps and ending the period at 207 bps. &lt;/div&gt;&lt;/td&gt; &lt;/tr&gt;&lt;/table&gt;

Conversely, the front end of the curve detracted from performance for the period with the Bloomberg Municipal Bond Index&#x2019;s 1&#x2011;year (1&#x2011;2 years) segment only up 2.36%. &lt;/div&gt;&lt;/td&gt; &lt;/tr&gt;&lt;/table&gt;&lt;div style="margin-top:12pt;margin-bottom:0pt;font-size:10pt;font-family:arial;font-weight:bold;"&gt;Top contributors to performance: &lt;/div&gt;

US Federal Reserve (Fed) cuts in 4Q25 and legislative clarity contributed to performance. However, the US&#x2011;Iran conflict and subsequent inflation concerns applied pressure to the market.

More importantly, the flows were evenly distributed between open-ended funds and exchange-traded funds (ETFs) in calendar year 2026.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt;

For example, the MMD AAA 2&#x2011;year yield rose 33 basis points (bps) while the 20&#x2011;year yield fell 15 bps and the 30&#x2011;year yield fell 1 bp (a basis point equals one&#x2011;hundredth of a percentage point). As a result, the 2&#x2011;year/30&#x2011;year curve flattened, starting the period at 241 bps and ending the period at 207 bps.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt;

For example, the Bloomberg Municipal Bond Index returned 4.12% while the long segment (22+ years) returned 6.45%; BBB&#x2011;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&#x2011;year (1&#x2011;2 years) segment only up 2.36%.&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt;  &lt;div style="margin-top: 12pt; margin-bottom: 0pt; font-size: 10pt; font-family: arial; font-weight: bold;"&gt;Top contributors to performance:&lt;/div&gt;
