Schedule of SAR Valuation Assumptions

The fair value of each SAR awarded was estimated on the grant date using a Black-Scholes option pricing model that uses various assumptions and estimates to calculate a fair value as described below.

Expected volatility was based on the actual trading volatility of the Company’s common stock.  The Company uses historical experience to estimate expected forfeitures and estimated terms.  The expected term of a SAR grant represents the period of time that the SAR is expected to be outstanding.  The risk-free rate is the U.S. Treasury Bond yield that corresponds to the expected term of each SAR grant.  Expected dividend yield is zero as the Company has not and does not foresee paying a dividend in the future.  Forfeitures are estimated to be zero based on the strike price and expected holding period of the SAR.

Expected volatility	29% — 31%
Expected term	7 years
Risk-free rate	4.3% — 4.7%
Expected dividend yield	—	%
Expected forfeiture rate	—	%
