Net Loss per Common Share

9 Months Ended

Sep. 30, 2020

Basic net loss per share is calculated based on the weighted average number of common shares outstanding during the period. Diluted net loss per share incorporates the dilutive effect of common stock equivalent options, warrants and other convertible securities, if any, as determined with the treasury stock accounting method. For the three and nine months ended September 30, 2020, since there was a net loss from continuing operations, the Company excluded all 1,705 and 1,430, respectively, in outstanding stock options and non-vested restricted shares from its diluted loss per share calculation, as inclusion of these securities would have reduced the net loss per share. For the three and nine months ended September 30, 2019, since there was a net loss from continuing operations, the Company excluded all 1,565 and 1,221, respectively, in outstanding stock options and non-vested restricted shares from its diluted loss per share calculation, as inclusion of these securities would have reduced the net loss per share.

A reconciliation of the basic and diluted weighted average common shares outstanding is as follows:
