        <footnote id="F2">Stock options were granted on December 3, 2018 under the NVR, Inc. 2018 Equity Incentive Plan and are subject to the achievement of a performance metric based on the Company's return on capital performance during the three-year period from 2019 through 2021. Effective March 4, 2022, it was determined by the Compensation Committee of the Board of Directors that the Company had achieved the required return on capital performance metric for the three-year performance period. Vesting for these stock options is now solely contingent upon the director's continued service.</footnote>
