Earnings Per Share [Abstract] |
Net Loss per Share | 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):
