Calculation of Basic and Diluted Net Loss Per Share Attributable to Common Stockholders

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

Weighted-Average Anti-Dilutive Shares of Common Stock Excluded from the Calculation of Diluted Net Loss Per Share

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):
