The dollar amounts reported in this column are the amounts of total compensation reported for Mr. Vashist (our Chief Executive Officer, and therefore our Principal Executive Officer (PEO)) for each corresponding year in the “Total” column of the Summary Compensation Table. Refer to “Executive Compensation –Summary Compensation Table.” 2. The dollar amounts reported in this column represent the amount of “compensation actually paid” to Mr. Vashist, as computed in accordance with Item 402(v) of Regulation S-K. The dollar amounts do not reflect the actual amount of compensation earned by or paid to Mr. Vashist during the applicable year. In accordance with the requirements of Item 402(v) of Regulation S-K, the following adjustments were made to Mr. Vashist’s total compensation for each year to determine the compensation actually paid: Year Reported Reported Equity Compensation Actually Paid to PEO ($) 2022 9,884,805 ( 8,407,824 ) ( 90,189,781 ) ( 88,712,800 ) 2021 10,912,539 ( 9,462,841 ) 111,941,071 113,390,769 2020 2,734,076 ( 1,716,359 ) 62,840,366 63,858,083 (a) The grant date fair value of equity awards represents the total of the amounts reported in the “Stock Awards” column in the Summary Compensation Table for the applicable year.

In accordance with the requirements of Item 402(v) of Regulation S-K, the following adjustments were made to average total compensation for the named executive officers as a group (excluding Mr. Vashist) for each year to determine the compensation actually paid, using the same methodology described above in Note 2: Year Average Average Average Equity Average Compensation Actually Paid to Non-PEO named executive officers ($) 2022 2,978,791 ( 2,462,247 ) ( 18,979,492 ) ( 18,462,948 ) 2021 3,705,832 ( 2,839,219 ) 21,336,276 22,202,889 2020 8,640,266 ( 8,435,652 ) 12,997,931 13,202,545 (a) The amounts deducted or added in calculating the total average equity award adjustments are as follows: Year Average Year over Year Average Change in Fair Value of Outstanding and Unvested Equity Awards ($) Average Fair Value as of Vesting Date of Equity Awards Granted and Vested in the Year ($) Year over Year Average Change in Fair Value of Equity Awards Granted in Prior Years that Vested in the Year ($) Average Fair Value at the End of the Prior Year of Equity Awards that Failed to Meet Vesting Conditions in the Year ($) Average Value of Dividends or other Earnings Paid on Stock or Option Awards not Otherwise Reflected in Fair Value or Total Compensation ($) Total 2022 2,882,706 ( 17,583,160 ) 123,166 ( 4,402,204 ) — — ( 18,979,492 ) 2021 3,313,601 15,860,448 257,863 1,904,364 — — 21,336,276 2020 12,877,771 — 120,160 — — — 12,997,931 5. C umulative TSR is calculated by dividing the sum of the cumulative amount of dividends for the measurement period, assuming dividend reinvestment, and the difference between our share price at the end and the beginning of the measurement period by our share price at the beginning of the measurement period. 6. Represents the weighted peer group TSR, weighted according to the respective companies’ stock market capitalization at the beginning of each period for which a return is indicated. The peer group used for this purpose is the following published industry index: Philadelphia Semiconductor Index. 7. The dollar amounts reported represent the amount of net income reflected in our audited financial statements for the applicable year. 8. While we use numerous financial and non-financial performance measures for the purpose of evaluating performance for our compensation programs, we have determined that revenue is the financial performance measure that, in our assessment, represents the most important performance measure (that is not otherwise required to be disclosed in the table) used by the company to link compensation actually paid to our named executive officers, for the most recently completed fiscal year, to company performance. | ||
