        <footnote id="F2">On May 14, 2024, the reporting person was granted performance stock units (PSUs) that were eligible to be earned based upon the registrant's achievement of specified financial metrics for 2024. On February 5, 2025, the registrant's Compensation Committee determined that the reporting person had earned 25,476 PSUs based on the 2024 financial metrics. The earned PSUs will vest as to 1/3 of the shares on May 14, 2025 and as to an additional 1/3 of the shares on each of December 31, 2025 and December 31, 2026, assuming the reporting person continues to be employed by the registrant on each such date.</footnote>
