For the three months ended February 28, 2023 and 2022, the Company recorded net loss available to common shareholders. As such, because the dilution from potential common shares was antidilutive, the Company used basic weighted-average common shares outstanding, rather than diluted weighted-average common shares outstanding when calculating diluted loss per share for the three months ended February 28, 2023 and 2022.

The following table sets forth the allocation of net loss for the three months ended February 28, 2023 and 2022, respectively:

The Company’s potential dilutive securities, which may include stock options and unvested restricted stock units 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 attributable to common stockholders is the same. 

The following potential common shares, presented based on amounts outstanding at each period end, were excluded from the calculation of diluted net loss per share attributable to common stockholders for the periods indicated because including them would have had an anti-dilutive effect:
