| | 6) | Net Income (Loss) Per Share of Common Stock |
Basic net income (loss) per share of common stock 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 net income (loss) per share.
Basic and diluted net income (loss) per share have been computed based on the following as of August 31, 2023 and August 31, 2022:
