| Additional 402(v) Disclosure [Text Block] | As required by Section 953(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act, and Item 402(v) of Regulation S-K, we are providing the following information about the relationship between executive compensation actually paid (as defined by SEC rules) and certain financial performance of the Company. The compensation and human capital committee did not consider the pay versus performance disclosure when making its incentive compensation decisions. For further information about how we align executive compensation with the Company’s performance, see “Compensation Discussion and Analysis” above. The amounts in the table below are calculated in accordance with SEC rules and do not represent amounts actually earned or realized by NEOs, including with respect to unvested restricted stock and unexercised stock options.The amounts disclosed represent the value of an investment of $100 in Common Stock at the end of each period presented assuming the investment was made at the beginning of each period presented. The total shareholder return used to determine these values was calculated by dividing the difference between the Company's share price at the end and the beginning of the measurement period by the Company's share price at the beginning of the measurement period. For 2021, the amount disclosed assumes that $100 was invested as of December 30, 2021, which is the first day our Common Stock began trading on the NYSE. While we utilize several performance measures to align executive compensation with performance, not all incentive measures are presented in the pay versus performance table above. We generally seek to incentivize long‐term performance and therefore do not specifically align performance measures with compensation that is actually paid (as computed in accordance with Item 402(v) of Regulation S‐K) for a particular year. We provide information below about the relationship between the compensation actually paid to our PEO and Non‐PEO NEOs for 2022 and 2021 as shown in the pay versus performance table above and: • our cumulative TSR; • our net income; and • our Adjusted EBITDA. Unranked List of the Company’s Most Important Financial Performance Measures A summary of the most important financial measures used by the Company to link compensation actually paid (as defined by SEC rules) to the Company's NEOs for the most recently completed fiscal year to the Company's performance are: • Adjusted EBITDA; • GTV; • Expansion; and • Dividends. | |
