Net Loss Per Share of Common Stock

NOTE 4 — NET LOSS PER SHARE OF COMMON STOCK

Diluted loss per share is the same as basic loss per share for all periods presented as the effects of potentially dilutive items were anti-dilutive given the Company’s net loss. Basic loss per share is computed by dividing net loss by the weighted-average number of common shares outstanding.

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

	Year Ended December 31,
	2018			2017
Net loss	$	(50,171,287	)	$	(31,523,207	)
Weighted average shares of common stock outstanding		38,792,581			37,937,191
Net loss per share of common stock – basic and diluted	$	(1.29	)	$	(0.83	)

The following securities outstanding at December 31, 2018 and 2017 have been excluded from the calculation of weighted average shares outstanding as their effect on the calculation of loss per share is antidilutive:

	December 31, 2018		December 31, 2017
Common stock options		8,498,047		6,132,650
Restricted stock units		127,300		185,950
