        <footnote id="F1">On May 21, 2026, the Issuer announced that an authorized committee of the Issuer's board of directors declared a special dividend on each of its outstanding common shares payable on June 16, 2026 to all holders of record as of 5:00 p.m., New York City time, on June 1, 2026 consisting of a special dividend of 0.10 shares of newly issued 9.0% Fixed Rate Cumulative Perpetual Redeemable Series A Preferred Shares (the &quot;Preferred Shares&quot;), having an initial liquidation price of $25 per Preferred Share (the &quot;Dividend&quot;). As a result of the Dividend, the reporting person directly received 12,216 Preferred Shares.</footnote>
        <footnote id="F2">Each Restricted Share Unit P (&quot;RSU&quot;) represents a right to receive one share of the Issuer's Series A Preference Shares at settlement.</footnote>
        <footnote id="F3">In connection with the Dividend, all RSUs with respect to the Issuer's common stock (&quot;Original RSUs&quot;) were adjusted pursuant to the anti-dilution provisions of the incentive plans under which the RSU awards held by the reporting person were granted. Each holder of an Original RSU was entitled to receive an RSU with respect to a number of Preferred Shares equal to 0.10 multiplied by the number of shares of common stock underlying the Original RSU, subject to the same terms and conditions as the Original RSU. These adjustments were approved by the compensation committee of the Issuer's board of directors pursuant to Rule 16b-3.</footnote>
        <footnote id="F4">The RSUs vest in three equal annual installments on March 15, 2027.</footnote>
