<PAGE 1> Exhibit 11 NAVISTAR INTERNATIONAL CORPORATION AND SUBSIDIARIES COMPUTATION OF NET INCOME PER COMMON SHARE A. Primary: See the Statement of Income of this Form 10-Q. B. Full Dilution: Net income per common share assuming full dilution is computed by assuming that all options and warrants which are exercisable below market prices are assumed to be exercised and the proceeds applied to reduce common stock outstanding. The computations assume that convertible preferred and preference stock are converted to common stock. Income is divided by the average number of common shares outstanding and unconditionally issuable at the end of each month during the period, adjusted for the net effects of the exercise of options and warrants and the conversion of convertible preferred and preference stocks.
