15. Quarterly Financial Data (Unaudited)

        We revised previously issued financial statements to correct errors identified principally related to accounting for income taxes. None of the revisions were considered material to the periods impacted, as disclosed in Note 1 of the consolidated financial statements included in this annual report on Form 10-K. The net income and basic and diluted earnings per share amounts indicated below have been revised as indicated in Note 1.
