Pay vs Performance Disclosure [Table] |  |  |
Pay vs Performance [Table Text Block] | PAY VERSUS PERFORMANCE The information provided below is mandated by the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 402(v) of Regulation S-K, which require that we, among other things, report the amount of “compensation actually paid” (“CAP”) to our named executive officers for the last three fiscal years and compare those amounts to certain mandated performance metrics. The values shown below under the header “compensation actually paid” is calculated in accordance with applicable SEC rules and does not reflect the actual amount of compensation earned by or paid to our named executive officers during each covered fiscal year. Our compensation philosophy is to deliver pay for performance. We seek to provide a level of performance that creates sustainable value for our stockholders by generating short-term results while also making investments designed to increase profitability over the long term. Please refer to the “Compensation Discussion and Analysis” section of this proxy statement for details regarding how the compensation committee links the compensation paid to our named executive officers to our company performance.

(1) | As required by applicable SEC rules, CAP was calculated by beginning with the total amount reported in the Summary Compensation Table (the “SCT”) for the applicable year, (i) subtracting the grant date fair value of stock awards reported in the “Stock Awards” column of the SCT (“Stock Awards”), (ii) subtracting the grant date fair value of option awards reported in the “Option Awards” column of the SCT (“Option Awards”), (iii) subtracting the actuarial present value of the accumulated benefit under defined benefit plans reported in the “Change in Pension Value and Non-Qualified Deferred Compensation Earnings” column of the SCT (“Change in Pension Value”), (iv) adding the change in fair value of stock and option awards for the applicable year, and (v) adding the service cost and prior service cost for all defined benefit plans for the applicable year.
| Fair value amounts were 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. The fair value amounts were calculated using our stock price on the last day of each fiscal year or the date of vesting, as applicable, and assuming the probable level of achievement for performance-based awards as of the end of the covered fiscal year. The service cost and prior service cost for defined benefit plans were calculated using the same methodology as used for our financial statements under generally accepted accounting principles.
| The following is a reconciliation of the SCT total and the CAP for the CEO for each of the covered fiscal years. Mr. Stanage is included as the CEO for each of the years reported in the table above.
