(3) Earnings (Loss) Per Common Share (EPS)

Basic earnings (loss) per common share (“EPS”) is computed by dividing net earnings (loss) attributable to common shareholders 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. Excluded from EPS for each of the three and nine months ended September 30, 2021 and the three and nine months ended September 30, 2020, are 1 million of potential common shares due to stock options, because their inclusion would be antidilutive. Also excluded from EPS for the nine months ended September 30, 2021, and both of

the three and nine months ended September 30, 2020, because their inclusion would be antidilutive, were 4 million and 13 million shares, respectively, that were contingently issuable at the Company’s election pursuant to an exercise of the Put Option (defined and described in note 6), as calculated in accordance with the terms of the Certificate of Designations for the Series A Preferred Stock. On March 29, 2021, pursuant to the Repurchase Agreement (described and defined in note 6), the Put Option no longer exists. The contingently issuable shares pursuant to the Put Option were calculated for the period that the Put Option was outstanding.
