Pay vs Performance Disclosure [Table] |  |  |
Pay vs Performance [Table Text Block] | PAY VERSUS PERFORMANCE The Securities and Exchange Commission (“SEC”) has adopted a new rule intending to compare “Pay versus Performance” as set forth below. This new rule requires the use of the term “Compensation Actually Paid” (CAP). The amounts shown in columns three and five below as “Compensation Actually Paid” do not reflect the compensation amounts actually paid or received by the Company’s NEO’s. In addition, while the table shows the Summary Compensation Table (SCT) compensation and CAP values side by side, they are not comparable. For a complete discussion of our executive compensation programs and the Compensation Committee’s approach and philosophy in aligning pay with performance for our NEOs, please see the “Compensation Discussion and Analysis” section of this Proxy Statement beginning on page 31. The “Compensation Actually Paid” portions of this table are calculated in accordance with the SEC rules and include amounts showing the potential value or change in value of long-term grants that may or may not be realized and not actual sums received during the respective calendar year. Furthermore, those potential benefits remained or continue to remain subject to the risks inherent in the Company’s performance and changes in the Company’s stock price prior to the period at which those performance-based grants could be realized.
