Pay Versus Performance Disclosure
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 compensation actually paid to our Named Executive Officers (“NEOs”) and certain financial performance metrics of the Company using a methodology that has been prescribed by the U.S. Securities and Exchange Commission. The disclosure does not necessarily reflect value actually realized by the NEOs or how the Committee evaluates compensation decisions in light of Company or individual performance. For discussion of how the Committee seeks to align pay with performance when making compensation decisions, please see the Compensation Discussion and Analysis beginning on page 29.
