Note 3 - Share-Based Compensation

We account for share-based awards under the provisions of ASC 718, “Compensation—Stock Compensation.” Accordingly, share-based compensation cost is measured at the grant date based on the fair value of the award and we expense these costs using the straight-line method over the requisite service period.

Share-based compensation expenses related to our restricted stock grants were $0.0 thousand and $6.0 thousand for the three months ended March 31, 2021 and 2020, respectively, which are reported as a separate line item in the consolidated statements of changes in stockholders’ deficit.

On April 20, 2021, pursuant to the 2015 Incentive Plan, we awarded a total of 945,000 shares of restricted stock to senior management, which are subject to a two-year or three-year cliff vesting, a total of 790,000 shares of restricted stock to key employees, which are subject to a three-year cliff vesting, and a total of 550,000 shares of restricted stock to the independent members of the Board of Directors, which are subject to a two-year cliff vesting. We also granted 300,000 shares of restricted stock to external consultants, which were fully vested at the grant date. The grant date price per share was $0.0631 for a total grant date fair value of $163.1 thousand.
