Net Loss Per Share [Abstract]
Net Loss Per Share	13. Net Loss Per Share The Company’s unvested restricted common shares have been excluded from the computation of basic net loss per share. The Company’s potentially dilutive securities, which include options, unvested restricted stock, convertible notes payable and convertible preferred stock, have been excluded from the computation of diluted net loss per share as the effect would be to reduce the net loss per share. Therefore, the weighted average number of common shares outstanding used to calculate both basic and diluted net loss per share is the same. The Company excluded the following potential common shares, presented based on amounts outstanding at each period end, from the computation of diluted net loss per share as of March 31, 2022 and March 31, 2021 because including them would have had an anti-dilutive effect: March 31, March 31, 2022 2021 Options and RSUs issued and outstanding 20,574,077 19,712,504 Warrants issued and outstanding stock 1,928,020 128,702 22,502,097 19,841,206
