NET LOSS PER COMMON SHARE

NET LOSS PER COMMON SHARE

13.    NET LOSS PER COMMON SHARE

Basic and diluted net loss per share of common stock has been computed by dividing net loss by the weighted average number of shares outstanding during the period. Diluted net loss per share of common stock is computed by dividing net income by the weighted average number of shares outstanding plus the dilutive effect, if any, of outstanding stock options, warrants and convertible securities. In a net loss period, options, warrants, unvested restricted securities and convertible securities are anti-dilutive and, therefore, excluded from diluted loss per share calculations.

For the three months ended March 31, 2021 and 2020, the following potentially dilutive securities were not included in the computation of net loss per share because the effect would be anti-dilutive:

Stock options	364,022	4,187
