quite well during the fiscal year, particularly during the first three fiscal quarters. </span><span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:10.02pt;color:#2D2D2D;;">The period opened with a sharp selloff following the announcement of global reciprocal tariffs on April 2, 2025, but as </span><span style="clear:both;font-family:Arial, Helvetica,

Economic </span><span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:10.02pt;color:#2D2D2D;;">fundamentals were healthy throughout the period despite the simmering trade war, and corporate earnings were strong. </span><span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:10.02pt;color:#2D2D2D;;">In addition, the Federal Reserve cut rates three times, which benefited nearly all asset classes. Sentiment finally shifted in </span><span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:10.02pt;color:#2D2D2D;;">the fourth fiscal quarter, primarily due to concerns about the economic fallout from the conflict in Iran.</span></div><div><span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:10.02pt;color:#2D2D2D;;">Although it was a bullish stretch for small cap growth stocks, it was still challenging for active managers, as lower-quality </span><span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:10.02pt;color:#2D2D2D;;">businesses and non-earners outperformed companies with solid fundamentals. The Fund’s underperformance was mostly </span><span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:10.02pt;color:#2D2D2D;;">driven by security selection, particularly within Health Care, where investor interest narrowed largely to speculative </span><span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:10.02pt;color:#2D2D2D;;">biotechnology stocks. Our medical device and life sciences tools companies underperformed despite strong revenue </span><span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:10.02pt;color:#2D2D2D;;">growth and increasing margins.

Within Information Technology, holdings exposed to semiconductor and hardware companies </span><span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:10.02pt;color:#2D2D2D;;">supporting AI infrastructure contributed positively, benefiting from strong demand in data centers, defense, and </span><span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:10.02pt;color:#2D2D2D;;">communications markets.</span></div><div><span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:10.02pt;color:#2D2D2D;;">For the fiscal year, our underperformance was also partially driven by our sector allocation.
