Net loss per share attributable to common stockholders

Basic and diluted net loss per share attributable to common stockholders was calculated as follows:


	Three months ended July 31,						Six months ended July 31,
	2020		2019		2020		2019
Numerator:
Net loss	$	(6,371)	$	(7,493)	$	(12,483)	$	(14,188)
Preferred stock dividend paid	—		(14,955)		—		(14,955)
Accretion of redeemable convertible preferred stock to redemption value	—		(48,312)		—		(56,175)
Net loss attributable to common stockholders	$	(6,371)	$	(70,760)	$	(12,483)	$	(85,318)
Denominator:
Weighted-average shares of common stock outstanding, basic and diluted	37,735,155		6,793,363		37,523,966		4,443,155
Net loss per share attributable to common stockholders	$	(0.17)	$	(10.42)	$	(0.33)	$	(19.20)

The Company’s potential dilutive securities, which include convertible preferred, stock options, restricted stock units and outstanding warrants to purchase shares of common and preferred stock, have been excluded from the computation of diluted net loss per share as the effect would be to reduce the net loss per share. Therefore, the weighted-average number of common shares outstanding used to calculate both basic and diluted net loss per share attributable to common stockholders is the same. The following potential common shares, presented based on amounts outstanding at each period end, were excluded from the calculation of diluted net loss per share attributable to common stockholders for the periods indicated because including them would have had an anti-dilutive effect:


	As of July 31,
	2020	2019
Stock options to purchase common stock and restricted stock units	6,185,126	6,649,129
Warrants to purchase common stock	75,137	303,315
	6,260,263	6,952,444
