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 nine months ended October 31, 2017 and 2016 (in thousands, except per share amounts):

	Three Months Ended						Nine Months Ended
	October 31,						October 31,
	2017			2016			2017			2016
Numerator:
Net loss attributable to common stockholders	$	(11,302	)	$	(6,694	)	$	(35,082	)	$	(30,999	)
Denominator:
Weighted-average common shares outstanding		53,779			18,420			52,388			9,987
Net loss per share attributable to common stockholders, basic and diluted	$	(0.21	)	$	(0.36	)	$	(0.67	)	$	(3.10	)

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:

	As of October 31,
	2017		2016
Options to purchase common stock		10,033,498		13,194,772
RSUs		1,963,015		32,422
Unvested common shares subject to repurchase		257,215		322,473
Shares committed under the ESPP		69,633		16,828
Convertible preferred stock warrants		-		36,971
Total		12,323,361		13,603,466
