Additional 402(v) Disclosure

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/fiscal year end date.

-Strike price is based on each grant date closing price and asset price is based on each vest/fiscal year end closing price.

-Risk free rate is based on the Treasury Constant Maturity rate closest to the remaining expected life as of the vest/fiscal year end date.

-Historical volatility is based on daily price history for each expected life (years) prior to each vest/fiscal year end date. Closing prices provided by S&P Capital IQ are adjusted for dividends and splits.

-Represents annual dividend yield on each vest/fiscal year end date.
