Due to the net loss to common stockholders in each of the periods presented above, diluted loss per share was computed without consideration to potentially dilutive instruments as their inclusion would have been anti-dilutive. As of January 31, 2021 and 2020, potentially dilutive securities excluded from the diluted loss per share calculation are as follows:
