| Pay vs Performance Disclosure | |||||
| Pay vs Performance Disclosure, Table | Pay Versus Performance As required by Section 953(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act, and Item 402(v) of Regulation S-K, we are providing the following information about the relationship between executive compensation actually paid and certain financial performance of the Company. The amounts reported in this table are not additional amounts received by our chief executive officer and non-PEO NEOs in excess of the amounts reported in the Summary Compensation Table (“SCT”). The “compensation actually paid” set forth in the table below does not reflect amounts actually realized by our NEOs, and the Compensation Committee did not consider the pay versus performance disclosure below when making compensation decisions for any of the years presented. For further information concerning the Company’s variable pay-for-performance philosophy and how the Company aligns executive compensation with the Company’s performance, refer to “Executive Compensation – Compensation Discussion and Analysis.” Fair value amounts below are computed in a manner consistent with the fair value methodology used to account for share-based payments in our financial statements under generally accepted accounting principles. Total shareholder return (“TSR”) has been calculated in a manner consistent with Item 402(v) of Regulation S-K.
