Compensation Actually Paid vs. Total Shareholder Return [Text Block] |  |  | Relationship Between Compensation Actually Paid to the PEO and Average Other NEOs and the Company's Cumulative Total Stockholder Return Our PEO's and other NEOs' compensation actually paid is not tied directly to the Company's total stockholder return ("TSR"), but it is expected that stockholder returns will generally correlate with the growth and profitability metrics that have been selected for the incentive program applicable to our NEOs and will impact the value of the equity awards granted to our NEOs. As calculated in accordance with the SEC disclosure rules, the compensation actually paid to our PEO was $3,117,996 for 2020, primarily driven by our EIP and stock price performance. During 2020, the Company’s TSR, measured assuming a $100 investment in the Company’s stock as of December 31, 2019, increased by approximately 10% to $110.41. Since December 31, 2020, our TSR, measured assuming a $100 investment in the Company’s common stock as of December 31, 2019, further increased to $114.36 as of December 31, 2022. The compensation actually paid to the PEO for 2022 was $3,047,616 and remained relatively consistent with the 2020 compensation actually paid to our PEO. Even though our TSR increased as compared to the 2020 TSR, due to the pay mix held by our then-serving PEO in 2020, which reflected a number of years of CEO-sized equity grants, as compared to the compensation of Mr. Leonard in 2022, which reflected his historical compensation levels as an EVP prior to his promotion, the 2022 PEO compensation actually paid was slightly less impacted by changes in TSR. The average compensation actually paid for our other NEOs was generally aligned with our TSR performance over the 2020-2022 period, with the average compensation actually paid for 2020 equal to $1,023,095 and increasing 8% to $1,106,669 as of December 31, 2022, as compared to a 14% TSR increase over the same period. |  |
Compensation Actually Paid vs. Net Income [Text Block] |  |  | Relationship Between Compensation Actually Paid to the PEO and Average Other NEOs and the Company's Net Income and Pre-Tax Income While pre-tax income is a significant component of our compensation program through its use in the EIP, our pre-tax income and, similarly, net income performance has less of an impact on our compensation actually paid due to the lower weighting of EIP in our overall compensation program as compared to equity awards. Accordingly, while our pre-tax income and net income increased by 68% and 76%, respectively, from 2020 to 2022, our PEO compensation actually paid slightly declined and the average compensation actually paid for the other NEOs increased by 8% over the same time period. |  |
