Note 9. Net Loss per Share

We calculate our basic and diluted net loss per share in conformity with the two-class method required for companies with participating securities. Under the two-class method, basic net loss per share is calculated by dividing the net loss by the weighted-average number of shares of common stock outstanding for the period, less shares subject to repurchase. The diluted net loss per share is computed by giving effect to all potential dilutive common stock equivalents outstanding for the period. For purposes of this calculation, options to purchase common stock, restricted stock units, employee stock purchase plan, repurchasable shares from early exercised options and unvested restricted stock, and contingently issuable shares are considered common stock equivalents but have been excluded from the calculation of diluted net loss per share as their effect is antidilutive.

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 and conversion. As the liquidation and dividend rights are identical, the undistributed earnings are allocated on a proportionate basis and the resulting net loss per share 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 as-if converted basis because the impact was not dilutive.

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

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

	Three Months Ended October 31,				Nine Months Ended October 31,
	2017		2016		2017		2016
Options to purchase common stock		11,997		13,036		12,094		13,900
Restricted stock units		13,962		10,249		13,382		9,623
Employee stock purchase plan		1,845		1,262		3,437		2,187
Repurchasable shares from early-exercised options and unvested restricted stock		164		312		206		350
Contingently issuable common stock		52		73		55		80
		28,020		24,932		29,174		26,140
