Stock-Based Compensation 2006 Equity Incentive Plan The Company’s 2006 Incentive Plan provides for the grant or issuance to officers, directors, employees and consultants of options with terms of up to ten years, restricted stock, stock unit awards (SUA’s), issuances of stock bonuses or other stock-based awards, covering up to 500,000 shares of common stock. As of June 30, 2015, 118,232 shares remained available for future grant under the 2006 Incentive Plan. On April 29, 2015 the Company granted SUAs covering 43,950 shares of common stock. The SUAs vest over a period of two years for non-employee board members and four years for employees and are convertible into an equivalent number of shares of the Company’s common stock provided that the director or employee receiving the award remains continuously employed throughout the vesting period. The Company records compensation expense related to the SUAs on a straight-line basis over the vesting term of the SUAs. Employees are issued shares upon vesting, net of tax withholdings, unless the employee chooses to receive all shares and pay for the associated employment taxes.
