NOTE 8 - STOCK-BASED COMPENSATION
Equity Incentive Plans
The Company has issued equity awards pursuant to its 2015 Equity Incentive Plan (the “2015 Plan”), 2009 Stock Plan and 2008 Stock Plan (collectively the “Plans”). The Plans permit the Company to grant non-statutory stock options, incentive stock options and other equity awards to the Company’s employees, outside directors and consultants; however, incentive stock options may only be granted to the Company’s employees. Beginning June 29, 2015, no further awards may be granted under the 2008 Stock Plan or 2009 Stock Plan. However, to the extent awards under the 2008 Plan or 2009 Plan are forfeited or lapse unexercised or are settled in cash, the common stock subject to such awards will be available for future issuance under the 2015 Plan.
On June 2, 2017, the stockholders of the Company approved an amendment to the 2015 Plan at the 2017 annual meeting of stockholders, which among other things, increased the number of shares that may be issued pursuant to awards under the 2015 Plan by 83,800 shares of common stock.
On September 15, 2017, the stockholders of the Company approved an amendment to the 2015 Plan at a special meeting of stockholders, which among other things, increased the number of shares that may be issued pursuant to awards under the 2015 Plan by 2,585,871 shares of common stock. As of September 30, 2019, the aggregate number of shares of common stock authorized for issuance under the 2015 Plan, as amended, was 2,750,000 and 183,124 shares were available for issuance as of September 30, 2019.
The following represents a summary of the options granted to employees and non-employees that are outstanding at September 30, 2019 and changes during the period then ended:
The exercise price for an option issued under the 2015 Plan is determined by the Board of Directors, but will be (i) in the case of an incentive stock option (A) granted to an employee who, at the time of grant of such option, is a 10% stockholder, no less than 110% of the fair market value per share on the date of grant; or (B) granted to any other employee, no less than 100% of the fair market value per share on the date of grant; and (ii) in the case of a non-statutory stock option, no less than 100% of the fair market value per share on the date of grant. The options awarded under the Plans will vest as determined by the Board of Directors but will not exceed a ten-year period.
