| Compensation Actually Paid vs. Total Shareholder Return [Text Block] | 5 6 7 Net income is the performance metric utilized for purposes of the Company’s annual cash incentive plan and is the only performance metric utilized for our NEOs’ compensation. Accordingly, we are presenting it as our company-selected measure required under Item 402(v) of Regulation S-K. Financial Performance Measures As described in greater detail in “Executive Compensation – Compensation Discussion and Analysis,” the Company’s performance – based executive compensation program is based exclusively on the Company’s net income with the objective of incentivizing our NEOs to increase the value of our enterprise for our shareholders. Compensation Actually Paid and Cumulative TSR As demonstrated by the following graph, the amount of compensation actually paid to Mr. McDearman and the average amount of compensation actually paid to the Company’s NEOs as a group (excluding Mr. McDearman) is aligned with the Company’s cumulative TSR over the three years presented in the table. The alignment of compensation actually paid with the Company’s cumulative TSR over the period presented is because a portion of the compensation actually paid to Mr. McDearman and to the other NEOs is comprised of stock options and/or cash-settled stock appreciation rights in one or more of the periods reflected. | ||
