Tabular List [Table Text Block] | As noted above, our compensation committee believes in a holistic evaluation of our executives’ and our Company’s performance and uses a mix of performance measures throughout our annual and long-term incentive programs to align executive pay with shareholder value creation. As required by SEC rules, the performance measures identified as the most important for named executive officers’ 2022 compensation decisions are listed below.
|  | For performance year 2022, our compensation committee identified the performance measures listed here as the most important in their compensation-setting process for the named executive officers. The importance of EBITDA is reflected by our use of this measure when setting performance standards applicable to short-term incentive plans. Our compensation committee utilizes EPS for purposes of setting long-term incentive performance goals.
