Adjustment To PEO Compensation, Footnote

The table below summarizes the reconciliation of compensation from the Summary Compensation Table above to compensation actually paid as calculated under SEC rules for fiscal year 2025. The valuation assumptions used to calculate the fair values of options, RSUs and PSUs include the stock price as of the applicable measuring date and, in the case of PSUs, the probable outcome of the performance conditions as of the applicable measuring date (or actual performance results approved by the Compensation Committee as of the applicable vesting date). Otherwise, the assumptions used to calculate fair values did not materially differ from those used in our disclosures of fair value as of the grant date. The Company does not have a pension plan or equity awards that vest in the same year that they are granted.
