28 Simplified Illustration of Diluted EPS a Earnings are allocated between those securities that have rights to participate in future dividend distributions based on their relati ve weighted average ownership interests. Losses are not allocated to participating securities because they are not contractually obligated to fun d o r otherwise share in those losses. b Example B assumes that stock options are dilutive after having applied the treasury stock method. c If using the “if converted” method resulted in lower diluted earnings per share than the two class method, the lower amount woul d g enerally be reported.
