Pay vs Performance Disclosure, Table

Pay Versus Performance

The following table presents information as required under Item 402(v) of SEC Regulation S-K regarding the relationship for the four most recently completed fiscal years between the compensation of our NEOs – as reported in the Summary Compensation Table and adjusted to reflect “compensation actually paid” (“CAP”) as defined under SEC rules – and our performance relative to the identified metrics. Our compensation philosophy and how we align executive compensation with our performance is described under “Compensation Discussion and Analysis.” The CAP amounts disclosed do not reflect the actual amount of compensation earned, realized, or received by our NEOs during the applicable fiscal year. The Compensation Committee did not consider the information provided in this section in making its compensation decisions for the years shown.
