Note 6. Stockholders’ Equity

Stock Options

In December 2007, we established the 2007 Equity Compensation Plan (the “2007 Plan”) and in November 2017 we established the 2017 Omnibus Incentive Plan (the “2017 Plan”), collectively (the “Plans”). The Plans were approved by our board of directors and stockholders. The purpose of the Plans is to grant stock and options to purchase our common stock, and other incentive awards, to our employees, directors and key consultants. On November 10, 2016, the maximum number of shares of common stock that may be issued pursuant to awards granted under the 2007 Plan increased from 5,000,000 to 7,000,000. On November 21, 2017, the Company’s stockholders approved the adoption of the 2017 Plan (previously adopted by our board of directors on September 14, 2017), which authorized a maximum of 1,874,513 shares of common stock that may be issued pursuant to awards granted under the 2017 Plan. On November 12, 2019, the Company's stockholders approved an increase in the maximum number of shares of common stock that may be issued pursuant to awards granted under the 2017 Omnibus Incentive Plan from 1,874,513 to 2,374,513. Upon adoption of the 2017 Plan we ceased granting incentive awards under the 2007 Plan and commenced granting incentive awards under the 2017 Plan. The shares of our common stock underlying cancelled and forfeited awards issued under the 2017 Plan may again become available for grant under the 2017 Plan. Cancelled and forfeited awards issued under the 2007 Plan that were cancelled or forfeited prior to November 21, 2017 became available for grant under the 2007 Plan. As of June 30, 2020, there were 622,429 shares available for grant under the 2017 Plan, and no shares were available for grant under the 2007 Plan. All incentive stock award grants prior to the adoption of the 2017 Plan on November 21, 2017 were made under the 2007 Plan, and all incentive stock award grants after the adoption of the 2017 Plan on November 21, 2017 were made under the 2017 Plan.

The majority of awards issued under the Plan vest immediately or over three years, with a one year cliff vesting period, and have a term of ten years. Stock-based compensation cost is measured at the grant date, based on the fair value of the awards that are ultimately expected to vest, and recognized on a straight-line basis over the requisite service period, which is generally the vesting period.
