| Compensation Actually Paid vs. Total Shareholder Return [Text Block] | As shown in the chart below, the CEO and Other NEOs compensation actually paid amounts are aligned with the Company’s TSR. This is due primarily to the Company’s use of equity awards, the value of which are tied directly to Company stock price performance, as well as the Company’s financial performance for PSU awards. Lower compensation actually paid to the CEO and Other NEOs in 2022 versus the prior year was substantially driven by a decline in the Company’s stock price, which resulted in a decrease in the fair value of equity awards, although our 2022 TSR outperformed peer group TSR for the year. Additionally, average compensation actually paid in 2022 for the Other NEOs declined materially versus 2021 due to the forfeiture of outstanding * In thousands except Company TSR. | ||
