(LOSS) INCOME PER COMMON SHARE

14. (LOSS) INCOME PER COMMON SHARE

Basic (loss) income per common share is computed by dividing net (loss) income allocable to common shareholders 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 share using the treasury stock method. For periods of net loss, basic and diluted per share information are the same.

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

Diluted	$	(4.07)	$	0.23	$	0.42

The Company had a net loss for the year ended December 31, 2018. As a result, basic and diluted loss per 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, RSAs and RSUs would have been 399,522.

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:

Service-based and earned performance-based stock options	4,147,027	3,242,919	1,542,064
Performance-based stock options	574,138	770,503	291,277
