Per Share of Common Stock
 
Basic net income (loss) per common share has been computed on the basis of the weighted average number of common shares outstanding. Diluted net income (loss) per share has been computed on the basis of the weighted average number of common shares outstanding plus equivalent shares assuming exercise of stock options. Potential shares of common stock that have an anti-dilutive effect (i.e., those that increase income per share or decrease loss per share) are excluded from the calculation of diluted earnings (loss) per common share.
 
Basic and diluted earnings (loss) per common share have been computed based on the following as of
May 31, 2018
and
May 31, 2017:
