[1] The Company has presented the dilutive effect of the Debentures using the if-converted method, assuming conversion at the beginning of the fiscal year for the years ended February 28, 2022 and February 29, 2020. Accordingly, to calculate diluted loss per share, the Company adjusted net income (loss) by eliminating the fair value adjustment made to the Debentures and interest expense incurred on the Debentures in the years ended February 28, 2022 and February 29, 2020, and added the number of shares that would have been issued upon conversion to the diluted weighted average number of shares outstanding. See Note 6 for details on the Debentures.

[2] The Company has not presented the dilutive effect of the Debentures using the if-converted method in the calculation of diluted loss per share for the year ended February 28, 2021, as to do so would be antidilutive. See Note 6 for details on the Debentures.
