(1)The change in Chad Richison’s position from Chief Executive Officer to Co-Chief Executive Officer, effective February 7, 2024, triggered the forfeiture of 1,610,000 shares of restricted stock granted to him on November 23, 2020, in accordance with the terms of the award. As a result, $117.5 million of previously recognized compensation costs that were recorded in reporting periods prior to 2024 were reversed to additional paid-in capital in the consolidated balance sheets and to general and administrative expenses in the consolidated statements of comprehensive income.
