Net loss per share attributable to common stockholders

12. Net loss per share attributable to common stockholders

The following table presents the calculation of basic and diluted net loss per share:

	Year ended December 31,
	2016			2015
Net loss		$	(2,554)		$	(8,501)
Weighted average shares outstanding			5,123,568			4,928,881
Basic and diluted loss per share		$	(0.50)		$	(1.72)

Because the Company was in a loss position for each of the periods presented, diluted net loss per share is the same as basic net loss per share for each period as the inclusion of all potential common shares outstanding would have been anti-dilutive. The following weighted average shares outstanding of common stock equivalents were excluded from the computation of diluted net loss per share for the periods presented because including them would have been anti-dilutive:

	Year ended December 31,
	2016		2015
Weighted average shares outstanding:
Common stock warrants		687,599		359,868
Options		2,044,902		1,122,197
Total		2,732,501		1,482,065
