Net Loss per Share |
Net Loss per Share | 12. Net Loss per Share 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 for the period, excluding shares subject to repurchase and without consideration of potentially dilutive securities. Diluted net loss per share is computed by giving effect to all potentially dilutive common shares outstanding for the period. For purposes of this computation, outstanding common stock options, and restricted stock units are considered to be common share equivalents. Common share equivalents are excluded from the computation in periods in which they have an anti-dilutive effect, unless the consideration of any one of them gives a dilutive effect. The Convertible Notes are convertible as of September 30, 2021. Upon conversion, the Company has the option to pay cash, issue shares of common stock, or any combination thereof for the aggregate amount due upon conversion. If converted, the value of the Convertible Notes based on contractual settlement provisions would exceed its principal amount by $564.6 million as of September 30, 2021. Since the Company is in a net loss position in the periods presented, the shares which would be issued upon conversion of the Convertible Notes are excluded from the net loss per share calculation as it would have an antidilutive effect. As such, the 7.4 million shares underlying the conversion option of the Convertible Notes will not have an impact on the Company’s diluted earnings per share. If converted, the Company does not intend to settle the obligation in cash. The following table provides the basic and diluted net loss per share computations for the nine months ended September 30, 2021 and 2020. ​
