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

Basic earnings (loss) per common share (“EPS”) is computed by dividing net earnings (loss) attributable to TripCo 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 both the three and nine months ended September 30, 2018 and 2017 are 2 million potential common shares, because their inclusion would be antidilutive.
