Pay vs Performance Disclosure |  |  |  |  |
Pay vs Performance Disclosure, Table | PAY VERSUS PERFORMANCE As required by the Dodd-Frank Wall Street Reform and Consumer Protection Act, and Item 402(v) of Regulation S-K (“Item 402”), we are providing the following information about the relationship between executive compensation actually paid (“CAP”) and certain financial performance measures of the Company. CAP is not compensation actually earned by or paid to our NEOs in each respective year. Neither the Compensation Committee nor the executives of our Company directly used the information in this table or the related disclosures when making compensation decisions for 2024. You should refer to the Compensation Discussion and Analysis in this Proxy Statement for a complete description of how executive compensation relates to Company performance and how the Compensation Committee makes its decisions. The following table shows the total compensation for our CEO and other NEOs as set forth in the Summary Compensation Table, the CAP to our CEO and other NEOs, our total shareholder return (“TSR”), the TSR of the S&P 600 Restaurants Index, our net income, and Adjusted EBITDA, our Company-select Performance measure, over the last five fiscal years.

As required by Item 402, the following table details adjustments made to Summary Compensation Table total compensation values to arrive at CAP values (Note that NEOs do not participate in a defined benefit plan so there are no adjustments for pension benefits, and similarly, there are no adjustments made for dividends): ​
