        <footnote id="F1">The DERs accrued on two outstanding RSU awards and vest proportionately with the RSUs to which they relate. The number of DERs is calculated as of the dividend record date by multiplying the dividend per share ($1.00) by the number of outstanding RSUs, and, to the extent applicable, previously accrued DERs and then dividing the result by the fair value of the common share on the dividend payment date. Each DER is the economic equivalent of one share.

Excludes DERs that accrued on outstanding RSUs prior to June 2, 2026, which are reflected in outstanding RSUs.</footnote>
        <footnote id="F2">Restricted stock units (RSUs) convert into Common Stock on a one-for-one basis.

The RSUs vested on June 2, 2026. Amounts reported include DERs that accrued on the RSUs prior to June 2, 2026.</footnote>
