Share-Based Compensation |
12. | SHARE-BASED COMPENSATION
On November 30, 2017, the Company’s shareholders approved the adoptions of the 2017 Employee, Director and Consultant Equity Incentive Plan (the “2017 Plan”). The 2017 Plan allows the Company, under the direction of the Compensation Committee of the Board of Directors, to make grants of restricted and unrestricted stock awards to employees, consultants and directors. The 2017 Plan allows for issuance of up to 1.4 shares of common stock. In addition, as of June 30, 2018, the Company may grant additional shares of common stock under the 2017 Plan with up to 1.3 options outstanding under its 2003 Plan and 6.5 options and restricted stock units outstanding under its 2010 Plan, that expire or are cancelled without delivery of shares of common stock. The number of shares, terms, and vesting periods are determined by the Company’s Board of Directors or a committee thereof on an option-by-option basis. Options generally vest ratably over service periods of four years. Options granted after December 5, 2012 expire eight years from the date of grant, and options granted prior to that date generally expire ten years from the date of grant. In September 2014, the Company began issuing restricted stock units (“RSUs”) in lieu of stock options. RSUs granted to employees generally vest ratably over four years on the anniversary date of the last day of the month in which the RSUs are granted. The number of RSUs awarded to certain executive officers may be reduced if certain additional performance metrics are not met. Options and RSUs granted to the Company’s non-employee directors vest in full upon completion of one year of service on the Board following the date of the grant.

Employee Stock Purchase Plan On December 5, 2012, following shareholder approval, the Company adopted the 2012 Employee Stock Purchase Plan (the “2012 Purchase Plan”), under which 2.0 shares of common stock have been authorized.
