Note 10. Net Loss per Share Attributable to Common Stockholders

Basic net loss per share attributable to common stockholders is calculated by dividing the net loss attributable to common stockholders by the weighted-average number of shares of common stock outstanding during the period, without consideration for potentially dilutive securities as they do not share in losses. During periods when the Company is in a net loss position, basic net loss per share attributable to common stockholders is the same as diluted net loss per share attributable to common stockholders as the effects of potentially dilutive securities are antidilutive given the net loss of the Company.

The following table sets forth the computation of the basic and diluted net loss per share attributable to common stockholders during the three and six months ended July 31, 2017 and 2016 (in thousands, except per share amounts):

	Three Months Ended						Six Months Ended
	July 31,						July 31,
	2017			2016			2017			2016
Numerator:
Net loss attributable to common stockholders	$	(13,742	)	$	(12,438	)	$	(23,780	)	$	(24,305	)
Denominator:
Weighted-average common shares outstanding		52,749			5,826			51,681			5,721
Net loss per share attributable to common stockholders, basic and diluted	$	(0.26	)	$	(2.13	)	$	(0.46	)	$	(4.25	)

Since the Company was in a loss position for all periods presented, basic net loss per share attributable to common stockholders is the same as diluted net loss per share for all periods as the inclusion of all potential common shares outstanding would have been anti-dilutive. Potentially dilutive securities that were not included in the diluted per share calculations because they would be anti-dilutive were as follows:
