| Pay vs Performance Disclosure, Table | Pay-Versus-Performance The following section has been prepared in accordance with the SEC’s pay versus performance disclosure rules mandated by the Dodd-Frank Act. Under these rules, the SEC has developed a new way to calculate executive pay, referred to as “compensation actually paid,” or CAP, which amounts are then compared to certain performance measures defined by the SEC. The CAP does not reflect the value received or realized by our NEOs or how the compensation committee evaluates compensation decisions in light of company performance. Please refer to “Compensation Discussion and Analysis” on page 38 for a discussion of our executive compensation program objectives and the ways in which we design our program to align executive compensation with company performance. The CAP values are derived from the total compensation amounts reported in the Summary Compensation Table, but adjusts those amounts to replace the grant date fair values of equity awards granted during the year with the fair value of equity awards granted during the year as of the end of the year, plus changes in fair value of any outstanding unvested awards granted in prior years. Thus, unlike the Summary Compensation Table that only factors in current year equity awards, the CAP reflects year-over-year changes in value of all outstanding unvested equity awards and equity awards vesting during the year. The CAP values also replace the change in pension value reported with the pension plan service cost or prior service cost for the year.
