Net Loss Per Share Attributable to Common Stockholders

Net Loss Per Share Attributable to Common Stockholders

We present net loss per share attributable to common stockholders using the two-class method required for multiple classes of common stock and participating securities. Holders of our Class A and Class B common stock have identical rights except with respect to voting, conversion and transfer rights and therefore share equally in our net losses. Prior to our IPO, we considered all series of our redeemable convertible preferred stock participating securities. We have not allocated net loss attributable to common stockholders to our redeemable convertible preferred stock because the holders of our redeemable convertible preferred stock are not contractually obligated to share in our losses.

We calculate basic net loss per share attributable to common stockholders by dividing net loss attributable to common stockholders by the weighted-average number of shares of common stock outstanding during the period. Diluted net loss per share attributable to common stockholders gives effect to all potential shares of common stock, including common stock issuable upon conversion of our redeemable convertible preferred stock and redeemable convertible preferred stock warrants, stock options, RSAs, RSUs and common stock warrants to the extent these are dilutive.

We calculated basic and diluted net loss per share attributable to common stockholders as follows (in thousands, except per share amounts):

Basic net loss per share is the same as diluted net loss per share because we reported net losses for all periods presented. We excluded the following weighted-average potential shares of common stock from our calculation of diluted net loss per share attributable to common stockholders because these would be anti-dilutive (in thousands):
