Pay vs Performance Disclosure [Table]

Pay vs Performance Disclosure, Table

Pay Versus Performance

As described in greater detail in our Compensation Discussion and Analysis beginning on page 46, our executive compensation program reflects a variable pay-for-performance philosophy. The following table and related disclosures provide further “pay versus performance” disclosure with respect to our Chief Executive Officer, also referred to as our principal executive officer (“PEO”), and our other named executive officers, or NEOs, as contemplated by Item 402(v) of Regulation S-K. The Compensation Committee did not consider the pay versus performance disclosure below in making its pay decisions for any of the years shown.

Award Timing Disclosures [Line Items]
Award Timing MNPI Disclosure	Timing of Equity Awards The Compensation Committee approves all long-term incentive compensation for our Named Executive Officers. The Compensation Committee meets in February each year to approve annual equity award grants to our Named Executive Officers, with individual grant values generally allocated between PSUs, RSUs and nonqualified stock option awards (see “2025 Long-Term Incentive Award Types” beginning on page 55). This meeting is scheduled each year to occur at least two business days following the public release of the Company’s earnings results for the prior year, at which time the Company generally expects all material nonpublic information to have been disclosed publicly and its regular trading window for its first quarter to have opened. The Compensation Committee also has authority to approve off-cycle grants for Named Executive Officers, which typically occur in connection with a new hire and are structured such that the grant date coincides with the first business day of the month following the Compensation Committee’s approval of such awards. To the extent applicable, the Compensation Committee will evaluate the potential impact of material nonpublic information when considering prospective equity awards to Named Executive Officers and does not time the disclosure of material nonpublic information for the purpose of affecting the value of executive compensation. The Compensation Committee did not grant equity awards to Named Executive Officers in fiscal 2025 during the period beginning four business days before, or one business day after (i) the filing of a periodic report on Form 10-Q or Form 10-K, or (ii) or the filing or furnishing of a current report on Form 8-K that discloses material non-public information.
