Earnings Per Share [Text Block]

2. Earnings Per Share

Basic earnings (loss) per share is computed by dividing the net loss for the period by the weighted-average number of common shares outstanding during the period. Diluted earnings (loss) per share (“EPS”) includes the dilutive effect of common stock equivalents and is computed using the weighted-average number of common stock and common stock equivalents outstanding during the reporting period. Diluted EPS for the three and nine months ended September 30, 2021 and 2020 excluded common stock equivalents because the effect of their inclusion would be anti-dilutive or would decrease the reported loss per share.

The following table sets forth securities outstanding that could potentially dilute the calculation of diluted earnings per share:
