(3)   Earnings (Loss) Per Common Share

Basic earnings (loss) per common share ("EPS") is computed by dividing net earnings (loss) by the weighted average number of common shares outstanding ("WASO") for the period. Diluted EPS presents the dilutive effect on a per share basis of potential common shares as if they had been converted at the beginning of the periods presented. Potentially dilutive shares are excluded from the computation of diluted EPS during periods in which losses are reported since the result would be antidilutive.

Excluded from diluted EPS for the three months ended September 30, 2021 and 2020 are 22 million and 29 million potential common shares, respectively, because their inclusion would have been antidilutive. Excluded from diluted EPS for the nine months ended September 30, 2021 and 2020 are 22 million and 29 million potential common shares, respectively, because their inclusion would have been antidilutive.
