Share-based Payment Arrangement [Abstract] |
STOCK-BASED COMPENSATION | STOCK-BASED COMPENSATION As of March 31, 2020, the Company had stock options, restricted stock awards, performance stock units, contract stock awards and restricted stock unit awards outstanding under two plans, the 2001 Equity Incentive Plan (the “2001 Plan”) and the 2003 Equity Incentive Plan (the “2003 Plan,” and collectively, the “Plans”). Stock options issued under the Plans become exercisable over specified periods, generally within four years from the date of grant for officers and employees, and within one year from date of grant for directors and generally expire eight years from the grant date for employees, and from six to ten years for directors and certain executive officers. The Company values stock option grants using the binomial distribution model. Restricted stock issued under the Plans vests over specified periods, generally three years after the date of grant. The vesting of performance stock issued under the Plans is subject to service and performance conditions. Stock Options As of March 31, 2020, there were approximately $8.2 million of total unrecognized compensation costs related to unvested stock options. These costs are expected to be recognized over a weighted-average period of approximately three years. There were 348,587 stock options granted during the three months ended March 31, 2020. For the three months ended March 31, 2020, the weighted average grant date fair value for stock options was $13.03 per option. Awards of Restricted Stock and Performance Stock Performance stock and restricted stock awards generally have requisite service periods of three years. Performance stock units are subject to graded vesting conditions based on revenue goals of the Company. The Company expenses the fair value of restricted stock awards on a straight-line basis over the requisite service period. As of March 31, 2020, there was approximately $37.3 million of total unrecognized compensation costs related to these unvested awards. The Company expects to recognize these costs over a weighted-average period of approximately two years. The Company granted 262,623 restricted stock awards and 180,875 performance stock awards during the three months ended March 31, 2020. For the three months ended March 31, 2020, the weighted average grant date fair value for restricted stock awards and performance stock units was $43.89 and $43.39 per award, respectively. The Company has no formal policy related to the repurchase of stock for the purpose of satisfying stock-based compensation obligations. The Company also maintains an Employee Stock Purchase Plan (the “ESPP”), which provides eligible employees with the opportunity to acquire shares of common stock at periodic intervals by means of accumulated payroll deductions. The ESPP is a non-compensatory plan based on its terms.
