Disclosure of Compensation Related Costs, Share-based Payments [Abstract] |
Share-Based Compensation Plans | Share-Based Compensation Plans We have shareholder approved equity incentive plans and a shareholder approved Section 423 Stock Purchase Plan (the “ESPP”). We account for stock awards to employees and non-employee directors under the fair value method. We determine the fair value of stock options at the grant date using the Black-Scholes valuation model. The model requires us to make estimates and assumptions regarding the expected life of the award, the risk-free interest rate, the expected volatility of our common stock price and the expected dividend yield. The fair value of restricted stock awards (“RSA”) is based on the common stock price on the date of grant. The fair value of stock awards is amortized to expense over the vesting period, generally four years. Share-based compensation reflected in the consolidated statements of operations were as follows:
