Allocation of Stock-based Compensation Expense The Company measures compensation expense for all stock-based payment awards based on the estimated fair values on the date of the grant. The fair value of stock options granted and ESPP issuances is estimated using the Black-Scholes option pricing model. The fair value of RSUs and PSUs are determined using the Company’s closing stock price on the date of grant. There have been no significant changes in the Company’s valuation assumptions from those disclosed in its 2023 Annual Report.
