        <footnote id="F1">Phantom stock units acquired pursuant to dividend equivalent rights in respect of previously reported phantom stock units (the &quot;Dividend Equivalent PSUs&quot;). The Dividend Equivalent PSUs accrued in connection with a cash dividend paid by the issuer on the issuer's common stock. The Dividend Equivalent PSUs will vest proportionately with the phantom stock units to which they relate. The Dividend Equivalent PSUs convert to the issuer's common stock on a one-for-on basis.</footnote>
