| Adjustment To PEO Compensation, Footnote | Amounts for each fiscal year do not reflect the actual amount of compensation earned by or paid to Mr. Weingarten during the applicable year. The amounts reported in this column for fiscal 2024 were calculated by making the following adjustments to amounts reported for Mr. Weingarten in the “Summary Compensation Table” in the “Total” column, in accordance with Item 402(v) of Regulation S-K: a. We deducted $15.1 million reported in the Summary Compensation Table, reflecting the grant date fair value of awards. b. We added $36.3 million reflecting the fair value of awards granted in the fiscal year that were outstanding and unvested as of the end of the fiscal year. c. We added $39.3 million representing the change in fair value of any awards granted in prior years that were outstanding and unvested as of the end of the fiscal year. d. We added $2.2 million representing the change in fair value of awards that were granted and vested in the same fiscal year. e. We added $3.9 million representing the change in fair value for awards granted in prior years that vested in the fiscal year.
