Net Loss Per Share Attributable to Common Stockholders

The following table sets forth the computation of the basic and diluted net loss per share attributable to common stockholders (in thousands, except share and per share amounts):



	Three months ended October 31,						Nine months ended October 31,
	2017			2016			2017			2016
Numerator:
Net loss attributable to common stockholders	$	(17,062	)	$	(10,222	)	$	(49,567	)	$	(28,577	)
Denominator:
Weighted-average common shares outstanding	90,353,608			31,092,270			73,992,705			31,031,276
Net loss per share attributable to common stockholders, basic and diluted	$	(0.19	)	$	(0.33	)	$	(0.67	)	$	(0.92	)

Basic net loss per share is computed by dividing the net loss attributable to common stockholders by the weighted average number of common shares outstanding during the period. Unvested restricted stock and restricted stock units are excluded from the denominator of basic net loss per share. Diluted net loss per share is computed by dividing the net loss attributable to common stockholders by the weighted average number of common shares plus common equivalent shares for the period, including any dilutive effect from such shares.

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 attributable to common stockholders, as the inclusion of all potential common shares outstanding would have been anti-dilutive. Anti-dilutive common equivalent shares were as follows:
