Schedule of Share-based Payment Award, Stock Options, Valuation Assumptions | The fair value of each of these option awards is estimated on the date of grant using the Black-Scholes option pricing model with the weighted average assumptions noted in the following table. Expected volatility is based on the historical volatility of the Company’s stock. Since the Company’s option exercise history is limited, it has estimated the expected term of these option grants to be the midpoint between the vesting period and the contractual term of each award. The risk free interest rate is based on the U.S. Treasury yield curve in effect on the date of grant which most closely corresponds to the expected term of the Time Vesting Options. The dividend yield is based on our historic average dividend yield. The Company did not grant any Time Vesting Options in fiscal 2014.
