We estimate the fair value of stock options granted using the Black-Scholes option pricing formula and a single option award approach. This fair value is then amortized on a straight-line basis over the requisite periods of the awards, which is generally the vesting period. The fair value of the Company’s stock options granted to employees for the nine months ended September 30, 2012 was estimated using the following weighted-average assumptions:
