(c) | The fair value of the stock options was determined using the Black Scholes model, which is consistent with the fair value methodology used to account for share-based payments in our financial statements.

(d) | The fair value of the Service RSUs was determined based on the stock price on the applicable valuation dates. The fair value of the Performance RSUs and the Diamond Acquisition Incentive Awards was determined based on the probable outcome of the performance condition and the stock price on the applicable valuation dates. The assumptions used in calculating the fair value of the Service RSUs, the Performance RSUs and the Diamond Acquisition Incentive Awards did not differ in any material respect from the assumptions used to calculate the grant date fair value of the awards as reported in the Summary Compensation Table for the applicable year, except that the fair value calculations of (i) the 2021 Performance RSUs and the Diamond Acquisition Incentive Awards as of December 31, 2022 and 2021, assumed a payout between target and maximum performance, which was the probable outcome of the applicable performance conditions as of December 31, 2022 and 2021, respectively, and (ii) the 2022 Performance RSUs as of December 31, 2022 assumed a payout at maximum performance, which was the probable outcome of the applicable performance conditions as of December 31, 2022, in each case compared to the grant date fair value calculations of such Performance RSUs, which assumed a payout at target. The fair value calculation used herein is consistent with the fair value methodology used to account for share- based payments in our financial statements.
