Pay vs Performance Disclosure, Table

PAY VERSUS PERFORMANCE

The following table shows the past four fiscal years’ Summary Compensation Table (“SCT”) pay, Compensation Actually Paid (“CAP”), our cumulative TSR, the cumulative TSR of our peer group over the same period, our net income, and our Adjusted Operating Earnings. As the table below demonstrates, there is a direct relationship between our financial outcomes and CAP to our Principal Executive Officer (“PEO”) and the average of CAP to the remaining Named Executive Officers (“NEOs”). The Compensation and Human Resources Committee believes that the Company’s pay-for-performance approach is working as designed.

The dollar amounts are the amounts of total compensation reported for James (“Joc”) C. O’Rourke for each corresponding year in the “Total” column of the SCT.

(2)The dollar amounts reported represent the amount of CAP to Mr. O’Rourke, as computed in accordance with Item 402(v) of Regulation S-K.

In accordance with the requirements of Item 402(v) of Regulation S-K, the following “PEO SCT Total to CAP Reconciliation” table displays the adjustments made to Mr. O’Rourke’s total compensation for each year to determine the CAP.

(3)The dollar amounts reported represent the average of the amounts reported for the Company’s NEOs as a group (excluding the PEO) in the “Total” column of the SCT in each applicable year.
