Numerator:
Net loss attributable to common stockholders	$	(16,106	)	$	(9,343	)
Denominator:
Weighted-average common shares outstanding	40,466,620			30,978,083
Net loss per share attributable to common stockholders, basic and diluted	$	(0.40	)	$	(0.30	)

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. 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. Common equivalent shares are convertible preferred stock, convertible preferred stock warrants, shares issuable upon the exercise of stock options and unvested shares of restricted stock units.

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:



	Three months ended April 30,
	2017	2016
Convertible preferred stock as converted	—	43,594,753
Series B warrants as converted	—	67,568
Series C warrants as converted	—	43,369
Common stock warrants	35,000	85,000
Options to purchase common stock	25,329,936	21,239,596
RSUs	270,000	40,000
Total	25,634,936	65,070,286
