9. Net Loss per Common Share

Basic and diluted net income (loss) per common share is determined by dividing net loss applicable to common shareholders by the weighted-average common shares outstanding during the period. Because there is a net loss attributable to common shareholders for the three months ended March 31, 2022, the outstanding RSUs, warrants and common stock options have been excluded from the calculation of diluted loss per common share because their effect would be anti-dilutive. For the three months ended March 31, 2021, there is net income attributable to common shareholders and, as a result, 256,461 warrants and 102,708 options in the money were included in the calculation of dilutive weighted average shares. As these shares were in the money at March 31, 2021, an additional 267,709 shares were included in the calculation of diluted net income per share.

The following potentially dilutive securities have been excluded from the computations of diluted weighted-average shares outstanding for the periods presented, as they would be anti-dilutive:
