Name Annual TSR        
Non-GAAP Measure Description We have selected Annual TSR as our most important financial measure (that is not otherwise required to be disclosed in the table) used to link “compensation actually paid” to our NEOs to company performance for fiscal year 2024. Annual TSR is expressed as a percentage and calculated using the following formula: (a) the sum of the closing price of the Company’s Common Stock on the last business day of the fiscal year plus dividends per share paid in that year, less (b) the closing price of the Company’s Common Stock on the last business day of the prior fiscal year, divided by (c) the closing price of the Company’s Common Stock on the last business day of the prior fiscal year.
