Earnings Per Share [Abstract] |
Net loss per share | 7. Net loss per share Basic and diluted net loss per share is computed by dividing net loss by the weighted-average number of common shares outstanding. Potentially dilutive securities were excluded from the diluted calculation because their effect would be anti-dilutive. The following tables set forth the computation of basic and diluted net loss per share: ​

* In the three and nine months ended September 30, 2021 and 2020, the Company experienced a net loss and therefore did not report any dilutive share impact. The following table shows historical dilutive common share equivalents outstanding, which are not included in the above historical calculation, as the effect of their inclusion is anti-dilutive during each period. ​
