Fair Value of Stock Appreciation Rights Estimated through Black-Scholes Option Pricing Model

The fair value of each time and performance SAR award is estimated on the date of grant using the Black-Scholes option pricing model with the assumptions described below for the periods indicated. Depending how long the Company’s common stock has been publicly traded at the grant date the expected volatility was based either on (i) an average of the Company’s historical volatility over the expected terms of the SAR awards and the comparable publicly traded companies historical volatility or (ii) the Company’s historical volatility over the expected terms of SAR awards. Estimated forfeitures were based on voluntary and involuntary termination behavior as well as analysis of actual forfeitures. The risk-free interest rate was based on the U.S. Treasury yield curve at the time of the grant over the expected term of the SAR grants.
