Earnings Per Share [Abstract] |
Earnings (Loss) Per Share | 13. EARNINGS (LOSS) PER SHARE Basic net loss per common share is calculated by dividing net loss attributable to common shareholders by the weighted-average number of common shares outstanding for the respective period. Diluted net loss per common share is calculated by dividing adjusted net loss by the diluted weighted average number of common shares outstanding, which includes the effect of potentially dilutive securities. Potentially dilutive securities for this calculation consist of stock options and warrants, which are measured using the treasury stock method, the conversion feature of the Series A Preferred Stock, and unvested shares of restricted common stock. When the Company recognizes a net loss attributable to common shareholders, as was the case for the three and six-month periods ended June 30, 2019 and 2018, all potentially dilutive shares are anti-dilutive and are consequently excluded from the calculation of dilutive net loss per common share. The following table sets forth the calculation of basic and diluted net loss per share.
