The dollar amounts reported represent the amount of “compensation actually paid,” as calculated in accordance with the Pay Versus Performance Rules. These dollar amounts do not reflect the actual amounts of compensation earned by or paid to our NEOs during the applicable year. For purposes of calculating “compensation actually paid,” the fair value of equity awards is calculated in accordance with ASC Topic 718 using the same assumption methodologies used to calculate the grant date fair value of awards for purposes of the Summary Compensation Table (refer to “Executive Compensation and Other Information – Summary Compensation Table” for additional information).

Consolidated Non-GAAP Operating Income

Non-GAAP Measure Description

We have determined that Consolidated Non-GAAP Operating Income (also referred to in our Compensation Discussion and Analysis as “Non-GAAP Operating Profit”) is the financial performance measure that, in the Company’s assessment, represents the most important financial performance measure used to link “compensation actually paid” to our NEOs, for fiscal year 2023, to company performance (the “Company Selected Measure” as defined in the Pay Versus Performance Rules). Please refer to the section titled “Elements of FY23 Executive Compensation – Financial Metrics for FY23” for the definition of Non-GAAP Operating Income and to Annex A for a reconciliation of Non-GAAP Operating Income to GAAP Operating Income.
