The fair value of the Company’s option awards to employees was estimated at the date of grant using the Black-Scholes option-pricing model. The risk-free rate was based on the U.S. Treasury yield curve in effect at the end of the quarter in which the grant occurred. The expected term of stock options granted was estimated using the historical exercise behavior of employees. Expected volatility was based on historical volatility measured using weekly price observations of the Company’s common stock for a period equal to the stock option’s expected term.
