Net Loss per Share Attributable to Common Stock

Note 15. Net Loss per Share Attributable to Common Stock

Basic loss per share of common stock is computed by dividing net loss attributable to common stockholders by the weighted average number of shares of common stock outstanding for the period. Diluted loss per share is calculated by adjusting the weighted-average number of shares outstanding for the dilutive effect of common stock equivalents outstanding for the period, determined using the treasury-stock method. Diluted loss per share excludes, when applicable, the potential impact of stock options, unvested shares of restricted stock awards, and common stock warrants because their effect would be anti-dilutive due to net loss.

The calculation of basic and diluted net loss per share attributable to common stock was as follows (amounts in thousands except share data):

	Three Months Ended				Nine Months Ended

	2022		2021		2022		2021

The following outstanding shares of common stock equivalents were excluded from the computation of the diluted net loss per share attributable to common stock for the periods presented because their effect would have been anti-dilutive:
