The Company estimates the fair value of share-based payment awards on the date of grant. The value of the portion of the award that is ultimately expected to vest is recognized as an expense over the requisite service periods in the Company's consolidated statements of operations.

The assumptions used in calculating the fair value of share-based payment awards represent the Company's best estimates. The Company's estimates of the fair values of stock options granted and the resulting amounts of share-based compensation recognized may be impacted by certain variables including stock price volatility, employee stock option exercise behaviors, additional stock option modifications, estimates of forfeitures, and the related income tax impact.
