Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
STOCK-BASED COMPENSATION	STOCK-BASED COMPENSATION As of March 31, 2014, the Company had stock options, restricted stock awards, performance stock awards, contract stock awards and restricted stock unit awards outstanding under three plans, the 2000 Equity Incentive Plan (the “2000 Plan”), 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, directors, and employees, and generally expire six years from the grant date for employees, and from six to ten years for directors and certain executive officers. 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, 2014, there were approximately $2.0 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 two years. There were 56,727 stock options granted during the three months ended March 31, 2014. Awards of Restricted Stock, Performance Stock and Contract Stock Performance stock, restricted stock and contract stock awards generally have requisite service periods of three years. Performance stock awards are subject to graded vesting conditions and the Company expenses their fair value over the requisite service period. The Company expenses the fair value of restricted stock and contract stock awards on a straight-line basis over the vesting period or requisite service period, whichever is shorter. As of March 31, 2014, there were approximately $21.5 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 204,397 restricted stock awards/stock units and 74,424 performance shares during the three months ended March 31, 2014. The Company has no formal policy related to the repurchase of shares 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.
