Adjustment To PEO Compensation, Footnote | For the unvested stock awards included in CAP for both the PEO and non-PEO NEOs, we used the closing stock price on the last trading day of each fiscal year, less the closing stock price on the last trading day in the immediately preceding fiscal year to obtain the incremental value of the unvested stock awards. The closing stock price of $56.70 and $67.56 was used for December 31, 2024 and December 29, 2023, respectively. For the vested awards included in CAP for both the PEO and non-PEO NEOs, we used the closing stock price on the vesting date, less the closing stock price on the last trading day of the fiscal year. The following tables reconciles the amount disclosed in our SCT to the amount disclosed for CAP for the PEO and non-PEO NEOs: PEO Reconciliation:
