Net Loss per Share of Common Stock

12 Months Ended

Dec. 31, 2021

Basic loss per share is based upon the weighted-average number of shares of common stock outstanding during the period, without consideration of common stock equivalents. Diluted loss per share is based upon the weighted-average number of common shares outstanding during the period plus additional weighted-average potentially dilutive common stock equivalents during the period when the effect is dilutive.

The following table presents the computation of basic and diluted loss per share of common stock (in thousands, except share and per share data) and the number of unexercised stock options and restricted stock units, which are common stock equivalents, that have been excluded from the diluted net loss calculation as their effect would have been anti-dilutive for all
