PAY VERSUS PERFORMANCE
As required by Item 402(v) of Regulation S-K, we are providing the following information regarding the relationship between the executive “compensation actually paid” to our principal executive officer (“PEO”) and our other named executive officer (“NEO”) and our financial performance foreach of the last three completed fiscal years. In determining the “compensation actually paid” (“CAP”) to our NEO, we are required to make various adjustments to amounts that have in prior years been reported in the Summary Compensation Table (“SCT”), as the SEC valuation methods for this disclosure differ from those required in the SCT. The values do not necessarily represent the actual compensation received by the NEO nor how the Compensation Committee evaluates and determines executive compensation levels. For our NEO other than our PEO, compensation is reported as an average.

The following summarizes the valuation assumptions used for stock option awards included as part of CAP:
Expected life of each stock option is based on the “simplified method” using an average of the remaining vest and remaining term, as of the vest/fiscal year end (“FYE”) date.
Strike price is based on each grant date closing price and asset price is based on each vest/FYE closing price.
Risk free rate is based on the Treasury Constant Maturity rate closest to the remaining expected life as of the vest/FYE date.
Historical volatility is based on daily price history for each expected life (years) prior to each vest/FYE date. Closing prices provided by S&P Capital IQ are adjusted splits.
Represents annual dividend yield on each vest/FYE date.
