(4) | The following summarizes the valuation assumptions used for stock option awards included as part of Compensation Actually Paid:
| • |  | 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/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 for dividends and splits.
| • |  | Represents annual dividend yield on each vest/FYE date.
(5) | Assumptions used in the valuation of equity awards for purposes of calculating Compensation Actually Paid were materially the same as at grant date, except for adjusting for expected performance of performance-based RSUs at each measurement date.
