| Stock-Based Compensation |
Note 4 - Stock-Based
Compensation
Under the fair value recognition provisions of
U.S. GAAP for accounting for stock-based compensation the Company measures stock-based compensation expense at the grant date based on the fair value of the award and recognizes the compensation expense over the requisite service period, which is
generally the vesting period.
The following table presents the
classification of stock-based compensation expense recognized for the periods below:
During the three months ended September 30, 2024, and 2023, under the 2017 Equity Incentive Plan, and the 2021 Inducement
Plan, the Company granted zero and 532
stock options, respectively, to its directors, officers and employees. During the nine months ended September 30, 2024 and 2023, the Company granted 1,264
and 3,544 stock options, respectively, to its directors, officers and employees. Vesting generally occurs over an immediate to 48-month period based on a time-of-service condition. The weighted-average grant date fair value of the stock-options issued during the three months
ended September 30, 2024 and 2023 was zero and $62.65 per share, respectively. The weighted-average grant date fair value of the stock options issued during the nine months ended September 30, 2024 and 2023 was $24.14 and $226.26 per share,
respectively.
The total number of stock options outstanding as of September 30, 2024 and September 30, 2023 was 3,890 and 3,101, respectively.
The weighted-average assumptions used in the Black-Scholes option-pricing model are as follows for the stock options granted during the three and nine months
ended September 30, 2024 and 2023:
During the three months ended September 30, 2024 and 2023, 420 and 69 stock options vested, respectively, and 102 and 595 stock options were expired
or forfeited during these periods, respectively. During the nine months ended September 30, 2024 and 2023, 1,767 and 129 stock options vested, respectively, and 465
and 680 stock options were expired or forfeited during these periods, respectively. During the three and nine months ended September
30, 2024 and 2023, no options were exercised.
