Net Loss per Share |
Net Loss per Share | 13. Net Loss per Share Basic net loss per share is computed by dividing the net loss by the weighted average shares outstanding. Diluted loss per share is computed by dividing the net loss by the weighted average diluted shares outstanding. The computation of basic and diluted loss per share (in thousands, except share and per share data) was as follows:
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | Year Ended December 31, | ​
​ |  | 2020 |  | 2019 |
Net loss | ​ | $ | (13,196) | ​ | $ | (15,213) | ​
Weighted average common shares outstanding | ​ |  | ​ | ​ |  | ​ | ​
Basic | ​ | ​ | 23,382,433 | ​ | ​ | 23,179,257 | ​
Dilutive common stock options, restricted stock unit awards and restricted stock awards | ​ | ​ | — | ​ | ​ | — | ​
Diluted | ​ | ​ | 23,382,433 | ​ | ​ | 23,179,257 | ​
Basic loss per share of common stock | ​ | $ | (0.56) | ​ | $ | (0.66) | ​
Diluted loss per share of common stock | ​ | $ | (0.56) | ​ | $ | (0.66) | ​
​ The Company had a net loss in the years ended December 31, 2020 and 2019. As a result, all stock options, restricted stock unit awards, and restricted stock awards were anti-dilutive and excluded from weighted average shares used in determining the diluted loss per share of common stock for the respective periods. The following weighted average numbers of stock options, restricted stock unit awards, and restricted stock awards have been excluded from the calculation of diluted loss per share of common stock, as their effect would be anti-dilutive for the years ended December 31, 2020 and 2019: ​
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | Year Ended December 31, | ​
​ |  | 2020 | ​ | 2019 | ​
Stock options | ​ | ​ | — | ​ | ​ | 50,580 | ​
Restricted stock units | ​ | ​ | 292,933 | ​ | ​ | 456,817 | ​
Restricted stock awards | ​ | ​ | — | ​ | ​ | 8,133 | ​
Total | ​ | ​ | 292,933 | ​ | ​ | 515,530 | ​
