| Tabular List [Table Text Block] | The most important financial performance measures used to link compensation for the most recently completed fiscal year were the following: Adjusted Revenues Adjusted Consolidated EBITDA Adjusted Operating Income Adjusted Net Income Adjusted EPS Operating Cash Flow Adjusted Organic Revenue These financial measures generally reflect those used internally to measure the Company’s performance and represent key drivers of sustainable stockholder value creation for our Company. We do not consider any one of the above performance measures to be the most important financial measure for our executive compensation design. However, for purposes of the table above, we have deemed Adjusted Consolidated EBITDA as our “most important” financial measure used to link our NEO’s compensation with performance because it is a key component of our 2022 annual bonus program and critical indicator of the Company’s growth and financial health used by our investors and stockholders. For more detail on we link these measures with performance of our NEOs, see “Compensation Discussion and Analysis — Design and Structure of Executive Compensation” on page 43 of this proxy statement. | ||
