Pay vs Performance Disclosure |  |  |  |  |  |  |
Pay vs Performance Disclosure, Table |  |  | Pay Versus Performance The following tables and related disclosures provide information about (i) the “total compensation” of our principal executive officer (“PEO”) and, on average, our other named executive officers (the “Other NEOs”) as presented in the Summary Compensation Table (the “SCT Amounts”), (ii) the “compensation actually paid” to our PEO and our Other NEOs, as calculated pursuant to the SEC’s pay-versus-performance rules (the “CAP Amounts”), (iii) certain financial performance measures, and (iv) the relationship of the CAP Amounts to those financial performance measures. This disclosure has been prepared in accordance with Item 402(v) of Regulation S-K under the Exchange Act and does not necessarily reflect value actually realized by the executives or how our Compensation Committee evaluates compensation decisions in light of Company or individual performance. For further discussion of how our Compensation Committee seeks to align pay with performance when making compensation decisions, please review the Compensation Discussion and Analysis section of this report. The Company’s executive compensation program reflects our pay-for-performance philosophy. Overall, our executive compensation is closely aligned with stockholder returns, as a substantial portion of compensation to our PEO and Other NEOs is in the form of long-term stock-based compensation awards, where the potential value that may be earned fluctuates depending on the movement of our stock price and/or the achievement of performance goals.
