s is calculated by replacing the value of these stock-based awards with an amount that reflects annual changes in the fair value of stock awards granted or held by the covered officer, including for each covered fiscal year:

◦ Grants of LTI Awards : the year-end fair value of the awards granted in the covered fiscal year that remain outstanding and unvested as of the end of the year;

◦ Vestings of LTI Awards : the change in fair value from the end of the prior fiscal year to the vesting date with respect to any awards granted in prior years that vested in the covered fiscal year;

◦ Forfeitures of LTI Awards : the loss in fair value as of the end of the prior fiscal year with respect to any awards granted in prior years that were forfeited in the covered fiscal year; and

◦ Prior LTI Awards that Remain Outstanding: the change in fair value from the end of the prior fiscal year to the end of the covered fiscal year with respect to any awards granted in prior years that are outstanding and unvested as of the end of the covered fiscal year.

Accordingly, a substantial portion of the amounts reported as CAP for the fiscal years indicated relate to unvested awards that are contingent upon unsatisfied service and performance requirements and that remain subject to stock price fluctuation. For a discussion of the amounts actually realized by our named executive officers upon the vesting of stock awards during fiscal 2025, see "— Options Exercised and Stock Vested."

The "Compensation Discussion and Analysis" section of this proxy statement sets forth the factors considered by the Human Capital and Compensation Committee (and with respect to our CEO, the independent directors on the Board) when reviewing and setting the compensation of our named executive officers for fiscal 2025. The amounts reported below as CAP, which are disclosed in accordance with the PVP rules, were not considered as part of this process.
