Net Loss per Share Attributable to Common Stockholders

Basic and diluted net loss per share attributable to common stockholders is presented in conformity with the two-class method required for participating securities.

Basic net loss per share attributable to common stockholders is computed by dividing the net loss by the weighted-average number of shares of common stock outstanding during the period, less shares subject to repurchase. Diluted net loss per share attributable to common stockholders is computed by giving effect to all potentially dilutive common stock equivalents outstanding for the period. For purposes of this calculation, stock options, unvested restricted stock awards, repurchasable shares from early exercised stock options, and shares subject to ESPP withholding are considered to be common stock equivalents but have been excluded from the calculation of diluted net loss per share attributable to common stockholders as their effect is anti-dilutive.

The rights, including the liquidation and dividend rights, of the holders of our Class A and Class B common stock are identical, except with respect to voting. As the liquidation and dividend rights are identical, the undistributed earnings are allocated on a proportionate basis and the resulting net loss per share attributed to common stockholders will, therefore, be the same for both Class A and Class B common stock on an individual or combined basis. We did not present dilutive net loss per share on an if-converted basis because the impact was not dilutive.

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



	Three Months Ended July 31,						Six Months Ended July 31,
	2016			2017			2016			2017
Net loss	$	(59,550	)	$	(61,701	)	$	(123,338	)	$	(124,075	)
Weighted-average shares used in computing net loss per share attributable to common stockholders, basic and diluted	192,730			209,193			191,026			207,515
Net loss per share attributable to common stockholders, basic and diluted	$	(0.31	)	$	(0.29	)	$	(0.65	)	$	(0.60	)

The following weighted-average outstanding shares of common stock equivalents were excluded from the computation of diluted net loss per share attributable to common stockholders for the periods presented because including them would have been anti-dilutive (in thousands):
