7. LOSS PER SHARE

The following table sets forth the computation of basic and fully diluted loss per share for the three and six months ended June 30, 2022 and 2021 (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 659,206 and 527,693 shares of common stock and warrants to purchase 3,940,006 and 3,665,005 shares of common stock were outstanding at June 30, 2022 and 2021 that were not included in the computation of diluted weighted average common stock outstanding because their effect would have been anti-dilutive.
