The Company provides stock-based awards through the 2013 Omnibus Incentive Plan which provides for awards of restricted stock, restricted stock units, stock options, stock appreciation rights, and cash awards to directors, emeritus directors, officers, employees, and advisory directors. The cost of equity-based awards under the 2013 Omnibus Incentive Plan generally is based on the fair value of the awards on their grant date. The maximum number of shares that may be utilized for awards under the plan is 2,962,400, including 2,116,000 for stock options and stock appreciation rights and 846,400 for awards of restricted stock and restricted stock units.

Shares of common stock issued under the 2013 Omnibus Incentive Plan may be authorized but unissued shares or, in the case of restricted stock awards, may be repurchased shares. As of June 30, 2013, the Company had repurchased all 846,400 shares on the open market for issuance under the 2013 Omnibus Incentive Plan, for $13,297, at an average cost of $15.71 per share.
