Net Loss per Share

6 Months Ended

Jun. 30, 2022

Basic net loss per share is calculated by dividing net loss attributable to common stockholders by the weighted average number of common shares outstanding during the period, less shares subject to repurchase, and excludes any dilutive effects of employee share based awards and options. Diluted net income per common share is computed giving effect to all potentially dilutive common shares, including common stock issuable upon exercise of stock options, convertible preferred stock, conversion of the Convertible Senior Notes, and unvested restricted common stock and stock units. As we had net losses for continuing operations for the three and six months ended June 30, 2022 and 2021, all potentially issuable common shares were determined to be anti-dilutive.

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