Share Based Compensation | 9 Months Ended
--- | ---
Sep. 30, 2012
Share Based Compensation | Share Based Compensation The Company’s 2010 Omnibus Incentive Plan (the “Plan”) permits the Company to grant to its officers, employees and non-employee directors incentive compensation directly linked to the price of the Company’s stock. 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”), performance shares 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. As of September 30, 2012, approximately 5,000,000 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 years 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. The Company grants restricted shares and RSUs with a grant date value equal to the closing stock price of the Company’s stock on the dates the shares or units are granted and they vest over a period of two to four years. The following schedule shows all options granted, exercised, and expired under the Plan for the nine months ended September 30, 2012 and 2011:
