Weighted average diluted common shares		322,500,592		211,000,091		317,219,129		206,560,031
Basic loss per share	$	(0.06)	$	(0.07)	$	(0.21)	$	(0.27)
Diluted loss per share (1)	$	(0.06)	$	(0.07)	$	(0.21)	$	(0.27)

(1) 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 April 30, 2021 and 2020, potentially dilutive securities excluded from the diluted loss per share calculation are as follows:
