Disclosure of Compensation Related Costs, Share-based Payments [Abstract] |
Stock-Based Compensation | Stock-Based Compensation Stock-based compensation expense reflects the fair value of stock-based awards measured at the grant date and recognized over the relevant service period. We estimate the fair value of each stock-based award on the measurement date using the current market price of the stock or the Black-Scholes option valuation model. In addition, during the first quarter of fiscal year 2014 and each of the first two quarters of fiscal year 2015, we granted performance-based restricted stock units that include a three-year market condition. In order to estimate the fair value of such awards, we used a Monte Carlo Simulation valuation model. The Black-Scholes and Monte Carlo Simulation valuation models incorporate assumptions as to stock price volatility, the expected life of options or awards, a risk-free interest rate and dividend yield. We recognize stock-based compensation expense related to options and restricted stock units on a straight-line basis over the service period of the award, which is generally 4 or 5 years for options and 3 years for restricted stock units. We recognize stock-based compensation expense related to performance stock units and our employee stock purchase plan using an accelerated attribution method. The following table provides the classification of stock-based compensation as reflected in our condensed consolidated statements of income (in thousands):
