Share-based Payment Arrangement [Abstract]

Share-Based Compensation

(10) Share-Based Compensation

We follow FASB ASC Topic 718, Compensation – Stock Compensation, in which compensation expense is recognized only for share-based payments expected to vest. We recognized compensation expense related to stock options of $48 and $147 for the three and nine months ended September 30, 2020, respectively, compared to $64 and $179 for the three and nine months ended September 30, 2019, respectively.

As of September 30, 2020, there was approximately $290 of total unrecognized compensation cost related to non-vested share-based compensation arrangements granted under our stock option plans. That cost is expected to be recognized over a remaining weighted-average period of 1.8 years.

Stock Options and Stock Grants

During the nine months ended September 30, 2020, 78,277 stock options were exercised for $23. During the nine months ended September 30, 2019, 36,000 stock options were exercised for $16.  During the nine months ended September 30, 2020, 535,000 stock options were granted, compared to 547,500 stock options granted during the same period in 2019. During the nine months ended September 30, 2020, 460,640 stock options expired compared to 130,500 for the same period in 2019. For the nine months ended September 30, 2020, 202,134 stock options were forfeited compared to 48,600 for the same period in 2019. We had 3,507,073 stock options outstanding at a weighted average exercise price of $0.58 on September 30, 2020, compared to 3,747,400 stock options outstanding at a weighted average exercise price of $0.64 on September 30, 2019.

No stock options were granted in the three-month periods ending September 30, 2020 and 2019.
