 option is estimated on date of grant using the Black-Scholes-Merton option pricing model. Determining the appropriate fair value model and calculating the fair value of employee stock options requires the use of subjective assumptions, including the expected life of the stock option and stock price volatility. The recognition of expenses for performance based restricted stock units requires us to estimate the probability that the performance condition will be achieved and the number of awards that will vest are adjusted accordingly at each reporting period. The assumptions used in calculating the fair value of employee stock options and estimating the probability of achievement of performance metrics represent management’s best estimates, which require significant judgment and involve inherent uncertainties. If factors change and we use different assumptions, our stock-based compensation expense could be materially different in the future.
