Net Loss Attributable to Common Stockholders

Note 13 – Net Loss Attributable to Common Stockholders:

Basic net loss per common share is calculated by dividing net loss attributable to common stockholders by the weighted-average number of common share outstanding for the period. Diluted net loss per common share is computed by giving effect to all potentially dilutive securities. Diluted net loss per common share is the same as basic net loss per common share, due to the fact that potentially dilutive securities would have an antidilutive effect as the Company incurred a net loss for the year ended December 31, 2015 and 2014.

The computation of net income attributable to common stockholders is as follows:

	Year ended December 31,
	2015			2014			2013
Net loss	$	(3,710,812	)	$	(37,339,017	)	$	(21,687,155	)
Preferred stock dividends on Series B and Series C		—			(11,286,193	)		(8,595,504	)
Additional loss attributable to common stockholders upon conversion of Series C Preferred Stock into common stock		—			(82,654,683	)		—
Net loss attributable to common stockholders	$	(3,710,812	)	$	(131,279,893	)	$	(30,282,659	)

The potentially dilutive securities excluded from the determination of diluted loss per share, as their effect is antidilutive, are as follows:

	Year ended December 31,
	2015		2014		2013
Convertible Preferred Series C (on an as-if converted basis)		—		—		7,713,455
Service Period Stock Options		1,991,209		1,220,739		1,092,604
Warrants		61,117		61,117		61,117
Total		2,052,326		1,281,856		8,867,176
