21. Net Loss per Common Share

21. Net Loss per Common Share


Basic loss per share is based on the weighted-average number of common shares outstanding during each year. Diluted loss per share is based on basic shares as determined above, plus the incremental shares that would be issued upon the assumed exercise of “in-the-money” warrants using the treasury stock method and the inclusion of all convertible securities, including convertible debentures, assuming these securities were converted at the beginning of the period or at the time of issuance, if later. The computation of diluted net loss per share does not assume the issuance of common shares that have an anti-dilutive effect on net loss per share.


For the years ended December 31, 2021 and 2020, the following options, warrants and convertible debentures were excluded from the computation of diluted loss per share as the result of the computation was anti-dilutive:
