NET LOSS PER SHARE |
NET LOSS PER SHARE | NOTE 13 NET LOSS PER SHARE Basic net loss per share is computed by dividing the net loss attributable to common shareholders by the weighted average number of common shares outstanding during the period. Potentially dilutive instruments are not included in the calculation of diluted net loss per share for the three months ended March 31, 2021 and 2020, as they would be anti-dilutive. For the three months ended March 31, 2021, all of the outstanding options (6,118,817) and all of the outstanding warrants (29,770,766) were excluded from the computation of diluted loss per share (March 31, 2020 – 4,430,784 outstanding options and 29,770,766 outstanding warrants). ​
