Net Loss Per Common Share

12. Net 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, without considering any dilutive items. Diluted net loss per common share is computed by dividing net loss by the sum of the weighted average number of common shares outstanding and the potential number of any dilutive common shares outstanding during the period. Potentially dilutive securities consist of the incremental common stock issuable upon exercise of stock options and convertible notes. Potentially dilutive securities are excluded from the computation if their effective is anti-dilutive. There were no dilutive common shares at December 31, 2017 and 2016. The numerators and denominators used in computing basic and diluted net loss per common share in 2017 and 2016 are as follows:

	December 31,
	2017			2016
Net loss available to common shareholders (numerator)	$	(5,277,316	)	$	(5,251,293	)
Weighted average shares (denominator)		3,717,956			1,247,281
Basic and diluted net loss per common share	$	(1.42	)	$	(4.21	)
