Share-Based Payment Arrangement [Abstract] |
Stock-Based Compensation | 13. Stock-Based Compensation From time to time, we issue stock options and restricted stock as compensation for services rendered by our directors and employees. Restricted Stock On January 6, 2022 and February 15, 2021, we issued 8,097 shares and 12,207 shares, respectively, of restricted common stock to our directors as part of their annual compensation plan. The grants of restricted common stock were made outside the 2015 Plan and were not subject to vesting. Stock compensation of $57,500 was recorded on this issuance of restricted common stock for the six months ended June 30, 2022 and 2021. Stock Options On April 14, 2022, we granted employees stock options to purchase 220,587 shares at an exercise price of $6.08 per share in accordance with the 2015 Plan, with vesting continuing until 2025. The total fair value of $1,152,470 for these stock options is being recognized over the requisite service period. We did not make any stock option grants during the six months ended June 30, 2021. The weighted-average grant date fair value of options granted during the three and six months ended June 30, 2022 was $5.22. The weighted average assumptions that were used in calculating such values during the six months ended June 30, 2022, as well as the assumptions that were used in calculating such values, were based on estimates at the grant date in the table as follows: Schedule of Estimated Values of Stock Option Grants Valuation Assumptions
