Equity-based Compensation

Note 12—Equity-based Compensation

Our board of directors adopted the 2009 Equity Incentive Plan (Plan) effective September 3, 2009. The Plan is intended to further align the interests of the Company and its stockholders with its employees, including its officers, non-employee directors, consultants and advisors by providing incentives for such persons to exert maximum efforts for the success of the Company. During the second quarter of 2013, the Plan allowed for the issuance of up to 1,200,000 shares of the Company’s common stock. Effective July 19, 2013, at the Annual Shareholders’ Meeting, the holders of common stock approved an amendment to the Company’s 2009 Equity Incentive Plan to increase the number of shares of common stock reserved for issuance under the plan from 1,200,000 to 2,600,000 shares.

The types of awards that may be granted under the Plan include options (both nonqualified stock options and incentive stock options), stock appreciation rights, stock awards, stock units, and other stock-based awards. The term of each award is determined by the Board at the time each award is granted, provided that the terms of options may not exceed ten years. The Plan had 637,993 options available for grant as of June 30, 2013. This amount does not include the additional 1,400,000 shares added to the Plan in July 2013.

Total stock-based compensation expense recognized using the straight-line attribution method in the Consolidated Statement of Operations is as follows:

The total fair value of shares vested during the six months ended June 30, 2013 was $0.6 million. As of June 30, 2013, there was $0.1 million of total unrecognized compensation cost, related to non-vested stock options which vest over time. That cost is expected to be recognized over a weighted-average period of 1.1 years. As of June 30, 2013, there was $0.3 million of total unrecognized compensation expense related to performance-based, non-vested consultant options.
