Earnings Per Share [Abstract] |
Net Loss per Share | Note 11. Net Loss per Share Material modification of rights of security holders On June 14, 2018, all of our outstanding shares of Class B common stock automatically converted into the same number of shares of Class A common stock pursuant to the terms of our Amended and Restated Certificate of Incorporation. No additional shares of Class B common stock will be issued following such conversion. The conversion occurred pursuant to Article IV of our Amended and Restated Certificate of Incorporation, which provided that each share of Class B common stock would convert automatically, without any further action, into one share of Class A common stock on the first trading day falling on or after the date on which the outstanding shares of Class B common stock represent less than 5% of the aggregate number of shares of the then outstanding Class A common stock and Class B common stock. On June 15, 2018, we filed a certificate with the Secretary of State of the State of Delaware effecting the retirement and cancellation of our Class B common stock. This certificate of retirement had the additional effect of eliminating the authorized Class B common stock, thereby reducing the total number of our authorized shares of common stock by 200,000,000. Our Class A and Class B common stock are referred to as common stock throughout the notes to the financial statements, unless otherwise noted. After June 14, 2018, common stock refers to our Class A common stock. For periods where there were Class B shares outstanding, 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, shares issuable pursuant to our employee stock purchase plan, shares subject to repurchase 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):
