Exhibit 11 Fully Diluted Earnings Per Common Share and Fully Diluted Average Common Shares Outstanding For fully diluted earnings per common share, net income available to common shareholders can be affected by the conversion of the registrant's convertible preferred stock. Where the effect of this conversion would have been dilutive, net income available to common shareholders is adjusted by the associated preferred dividends. This adjusted net income is divided by the weighted average number of common shares outstanding for each period plus amounts representing the dilutive effect of stock options outstanding and the dilution resulting from the conversion of the registrant's convertible preferred stock, if applicable. The effect of convertible preferred stock is excluded from the computation of fully diluted earnings per share in periods in which the effect would be antidilutive. Fully diluted earnings per common share was determined as follows (shares in thousands, dollars in millions except per-share information): Three Months Ended Six Months Ended June 30 June 30 ------------------ ------------------ 1994 1993 1994 1993 -------- -------- -------- -------- Average common shares outstanding........................... 275,020 254,002 273,492 253,673 Dilutive effect of Convertible preferred stock............................... 2,371 2,465 2,371 2,465 Stock options............................................. 1,736 1,340 1,634 1,693 -------- -------- -------- -------- Total fully dilutive shares................................. 279,127 257,807 277,497 257,831 ======== ======== ======== ======== Income available to common shareholders before effect of change in method of accounting for income taxes........ $ 435 $ 304 $ 849 $ 583 Preferred dividends paid on dilutive convertible preferred stock........................................... 2 2 4 4 -------- -------- -------- -------- Income available to common shareholders adjusted for full dilution and before effect of change in method of accounting for income taxes............................ 437 306 853 587 Effect of change in method of accounting for income taxes... - - - 200 -------- -------- -------- -------- Total net income available for common shareholders adjusted for full dilution................................ $ 437 $ 306 $ 853 $ 787 ======== ======== ======== ======== Fully diluted earnings per common share before effect of change in method of accounting for income taxes........ $ 1.57 $ 1.19 $ 3.07 $ 2.28 ======== ======== ======== ======== Fully diluted earnings per common share..................... $ 1.57 $ 1.19 $ 3.07 $ 3.05 ======== ======== ======== ======== 61
