Compensation Actually Paid vs. Total Shareholder Return [Text Block] |  |  | Analysis of the Information Presented in the Pay versus Performance Table As described in more detail in the sections entitled “COMPENSATION DISCUSSION AND ANALYSIS” and “EXECUTIVE COMPENSATION,” our executive compensation program reflects a variable pay-for-performance philosophy, with a significant emphasis on long-term performance and stockholder value creation. While we utilize several performance measures to align executive compensation with our performance, all of those measures are not presented in the Pay versus Performance table. Furthermore, while we are required to disclose our net income for each covered fiscal year, it is not a metric currently used in our executive compensation program. We generally seek to incentivize long-term performance, and therefore do not specifically align our performance measures with compensation that is actually paid (as computed in accordance with Item 402(v) of Regulation S-K) for a particular year. In accordance with rules adopted by the SEC, we are providing the following descriptions of the relationships between information presented in the Pay versus Performance table. Comparison of Compensation Actually Paid and Company TSR The following graph reflects the relationship between our CEO and average non-CEO NEO “compensation actually paid” versus our cumulative TSR, assuming an initial fixed investment of $100 on December 31, 2019, for the years ended December 31, 2022, 2021 and 2020. |  |

Tabular List [Table Text Block] |  |  | Financial Performance Measures As further described in the section above entitled “COMPENSATION DISCUSSION AND ANALYSIS – Components of Executive Compensation,” the Company’s executive compensation program is heavily weighted to performance-based pay, with a significant emphasis on long-term performance and stockholder value creation. The Company primarily uses two core metrics for both its long-term and short-term incentive awards: Adjusted EPS and Adjusted EBITDA. The Company uses Adjusted EPS and Adjusted EBITDA to determine annual cash incentive awards and performance-based equity awards because they are important measures of our performance and the performance of our management, they drive our success and growth and they are key criteria by which management plans and analyzes our business. In addition, the Company uses certain non-financial measures to determine annual cash incentive awards in order to incentivize and align achievement for certain key qualitative metrics. Therefore, the most important financial performance measures (and only financial measures used in current plans/awards) used by the Company to link compensation actually paid to the Company’s NEOs, for the most recently completed fiscal year, to the Company’s performance are as follows:
| ● | Adjusted EPS
| ● | Adjusted EBITDA
Total Shareholder Return Amount |  |  | $ 247 | 183 | 151
Peer Group Total Shareholder Return Amount |  |  | 118 | 147 | 134
