Explanation of Responses:

( 1 )874.3 DERs accrued on two outstanding RSU awards and vest proportionately with the RSUs to which they relate. 1,063.0 DERs also accrued on previously deferred RSUs. The total number of accrued DERs is calculated as of the dividend record date by multiplying the dividend per share ($1.00) by the number of outstanding RSUs, deferred RSUs and, to the extent applicable, previously accrued DERs and then dividing the result by the fair value of the common stock 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. ( 2 )Restricted stock units (RSUs) convert into Class A Common Shares 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. ( 3 )Deferral of RSUs that vested on June 2, 2026 and related deferral of DERs that accrued on such RSUs on June 2, 2026. Each deferred RSU represents a vested right to receive one share of Class A Common Shares of the issuer. The vested units may be released at the time the reporting person elects, no later than 10 years from the grant date.

Reminder: Report on a separate line for each class of securities beneficially owned directly or indirectly.
