NOTE 5 - EARNINGS PER SHARE ATTRIBUTABLE TO INTERNATIONAL PAPER COMPANY COMMON SHAREHOLDERS

Basic earnings per common share are computed by dividing earnings by the weighted average number of common shares outstanding. Diluted earnings per common share are computed assuming that all potentially dilutive securities were converted into common shares.
