Net Loss per Common Share

11. 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 March 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:

	March 31,
	2017			2016
Net loss attributable to common stockholders (numerator)	$	(906,855	)	$	(1,014,679	)
Weighted average shares (denominator)		2,614,324			758,542
Basic and diluted net loss per common share	$	(0.35	)	$	(1.34	)

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, 2016 and 2015. The numerators and denominators used in computing basic and diluted net loss per common share in 2016 and 2015 are as follows:

	December 31,
	2016			2015
Net loss available to common stockholders (numerator)	$	(5,251,293	)	$	(3,601,066	)
Weighted average shares (denominator)		1,247,281			762,506
Basic and diluted net loss per common share	$	(4.21	)	$	(4.72	)
