Abstract Research is undertaken to investigate the impact on users of the requirement in APB Opinion 15 calling for reporting of fully diluted earnings per share amounts on income statements. An impact on users is inferred if, around the time of first reporting under Opinion 15, one can observe different patterns of stock prices between two groups of firms: a group which reported fully diluted earnings per share in the first financial reports issued under the Opinion and a group which did not. Such differential patterns were observed, but they began at least a year before the date Opinion 15 became mandatory.
