Additional 402(v) Disclosure | The amounts reported in columns (c) and (e) represent Compensation Actually Paid to each of the PEOs and the average Compensation Actually Paid to the Non-PEO Named Executive Officers, respectively, calculated in accordance with Item 402(v) of Regulation S-K. Total compensation reported in the Summary Compensation Table is the starting point to determine Compensation Actually Paid, and then certain adjustments are made to those amounts with respect to equity-based and other compensation, as detailed below. For equity-based awards granted during the fiscal year, the amount reported in the Stock Awards column of the Summary Compensation Table is replaced with the fair value of the awards at the end of the fiscal year or on the vesting date, if earlier. For equity-based awards made in prior fiscal years which vested during the fiscal year, the change in fair value from the end of the prior fiscal year to the vesting date is added, and for equity-based awards made in prior fiscal years that remained unvested at fiscal year end, the change in fair value from the end of the prior fiscal year to the end of the fiscal year is added. For any equity-based awards granted in a prior fiscal year that failed to meet the applicable vesting requirements during the fiscal year, the fair value at the end of the prior year is deducted. Finally, the dollar value of any dividends or other earnings paid on any equity-based awards in the fiscal year prior to the vesting date that are not otherwise included in total compensation are added. For defined benefit and actuarial pension plans, the aggregate change in the actuarial present value of the NEO’s accumulated benefits under all such plans is replaced with the (i) service cost, calculated as the actuarial present value of the NEO’s benefits under all such plans attributable to services rendered during the fiscal year, and (ii) prior service cost, calculated as the entire cost of benefits granted (or credit for benefits reduced) in a plan amendment (or initiation) during the fiscal year that are attributed by the benefit formula to services rendered in periods prior to the amendment. In accordance with Item 402(v) of Regulation S-K, we determined operating income, as adjusted by the Compensation Committee, as the most important financial performance measure (that is not otherwise disclosed in this table) we used to link Compensation Actually Paid to our NEOs for fiscal year 2025 to our performance, given its impact on the determination of the change in fair value of performance shares granted to the NEOs. For fiscal year 2025, the Committee approved adjustments to operating income for (1) restructuring costs and (2) a gain on the sale of land, net of variable compensation impacts. For fiscal year 2024, the Committee approved adjustments to operating income for (1) restructuring costs and (2) a decrease in the valuation of a contingent earnout liability. For fiscal year 2023, the Committee approved adjustments to operating income for (1) restructuring costs and (2) an increase in the valuation of a contingent earnout liability. For fiscal year 2022, the Committee approved adjustments to operating income for (1) a gain from a cost-method investment and (2) the incremental increase in CEO compensation during our CEO transition period. For fiscal year 2021, operating income was not used as a financial performance measure for incentive compensation purposes, so the Committee did not approve any adjustments, but we have presented fiscal year 2021 operating income, as adjusted to exclude (1) restructuring costs and (2) a goodwill impairment charge, consistent with adjustments historically approved by the Committee. |  |  |  |  |  |
