LOSS PER COMMON SHARE

LOSS PER COMMON SHARE

11.  LOSS PER COMMON SHARE

Basic loss per common share is computed by dividing net loss by the weighted average number of common shares outstanding during the period. Diluted income per common share further includes any common shares available to be issued upon exercise of outstanding service-based stock options; exercise of outstanding performance-based stock options for which all performance conditions were satisfied; and satisfaction of all contingent consideration performance conditions; and RSAs and RSUs, if such inclusions would be dilutive. The potentially dilutive common shares are determined for inclusion in diluted income per common share using the treasury stock method. For periods of net loss, basic and diluted per common share information are the same.

The following table sets forth the computation of basic and diluted loss per common share:

The Company had a net loss for the three months ended September 30, 2019 and nine months ended September 30, 2019 and 2018.  As a result, basic and diluted loss per common share were the same as any potentially dilutive securities would be anti-dilutive.  In the absence of a net loss, the weighted average dilutive effect of stock options, RSUs and RSAs would have been 235,830 for the three months ended September 30, 2019 and 399,746 and 383,742 for the nine months ended September 30, 2019 and 2018, respectively.

The weighted average effect of certain common stock equivalents including stock options, RSUs and RSAs were excluded from the computation of weighted average diluted shares outstanding as inclusion of such items would be anti-dilutive, are summarized as follows:
