        <footnote id="F2">Restricted stock units that convert into common stock on a one-for-one basis.  One-third of the restricted stock units vests on each of May 5, 2024, May 5, 2025 and May 5, 2026.</footnote>
        <footnote id="F3">Reflects performance-based phantom units that vested on May 5, 2023. Each phantom unit represented the right to receive a cash payment in an amount equal to the average closing price of one share of common stock of the Company, par value $0.01 per share (a &quot;Share&quot;) on the principal stock exchange on which the Shares were then listed for the twenty consecutive trading days preceding March 31, 2023.</footnote>
        <footnote id="F4">No shares were actually issued, disposed or sold. Under applicable SEC guidance, cash settlement of phantom units is deemed to involve the conversion of the phantom units into the underlying common stock and the simultaneous disposition of the common stock to the Company for cash. Accordingly, Table 1 uses Transaction Code D to report the phantom unit settlement.</footnote>
