Share Based Compensation | 12 Months Ended

Dec. 31, 2011
Share Based Compensation | ## 15. Share Based Compensation During 2010, the Company adopted the 2010 Omnibus Incentive Plan (the “Plan”), which permits the Company to grant to officers, employees and non-employee directors of the Company incentive compensation directly linked to the price of the Company’s stock. This plan replaced the 2005 Equity Incentive Plan. The Plan authorizes up to an aggregate of 6,045,511 shares of Company stock for awards of options to purchase shares of the Company’s common stock, restricted stock, restricted stock units (“RSU”) or appreciation rights. Shares used may be either newly issued shares or treasury shares or both. The aggregate number of shares of common stock for which awards may be issued may not exceed 6,045,511 shares, subject to the authority of the Company’s board of directors to adjust this amount in the event of a consolidation, reorganization, stock dividend, stock split, recapitalization or similar transaction affecting the Company’s common stock. All remaining unissued shares related to the Company’s previously existing 2005 and Equity and Incentive Plan were absorbed into the Plan. As of December 31, 2011, approximately 5,500,000 shares of Company common stock remained available for grants under the Plan. The Company recognizes compensation expense under FASB ASC 718-10-25 for its share-based payments based on the fair value of the awards. The Company grants stock options at prices equal to the closing stock price of the Company’s stock on the dates the options are granted. The options have a term of ten years from the date of grant and vest primarily in equal annual installments over the four-year period following the date of grant for employee options. Employees have three months after the employment relationship ends to exercise all vested options. The fair value of each option grant is separately estimated for each vesting date. The fair value of each option is amortized into compensation expense on a straight-line basis between the grant date for the award and each vesting date. The Company has estimated the fair value of all stock option awards as of the date of the grant by applying the Black-Scholes-Merton multiple-option pricing valuation model. The application of this valuation model involves assumptions that are judgmental and highly sensitive in the determination of compensation expense. A summary of the Company’s stock option activity for the years ended December 31, 2011, 2010 and 2009 is shown below:
