11. LOSS PER SHARE

The following table sets forth the computation of basic and fully diluted loss per common share for the years ended December 31, 2023 and 2022 (stated in thousands, except per share amounts):

​

​

Basic net loss per share is computed using the weighted average number of common shares outstanding during the period. Diluted net loss per share is computed using the treasury stock method to calculate the weighted average number of common shares and, if dilutive, potential common shares outstanding during the period. Potential dilutive common shares include incremental common shares issuable upon the exercise of stock options, less shares from assumed proceeds. The assumed proceeds calculation includes actual proceeds to be received from the employee upon exercise and the average unrecognized stock compensation cost during the period.

Stock options to purchase 36,425 and 49,040 common shares and warrants to purchase 194,974 and 206,000 common shares were outstanding at December 31, 2023 and 2022, respectively, that were not included in the computation of diluted weighted average common shares outstanding because their effect would have been anti-dilutive.
