Exhibit 11
Diluted Earnings Per Common Share and
Diluted Average Common Shares Outstanding
For 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 diluted earnings per common share in periods in which the effect
would be antidilutive.
Diluted earnings per common share was determined as follows (shares in
thousands, dollars in millions except per-share information):
