1 EXHIBIT 11 THE CHASE MANHATTAN CORPORATION COMPUTATION OF NET INCOME PER SHARE Net income for basic and diluted EPS is computed by subtracting from the applicable earnings the dividend requirements on preferred stock to arrive at earnings applicable to common stock. Basic EPS is computed by dividing net income available to common shares outstanding by the weighted-average number of common shares outstanding for the period. Diluted EPS is computed using the same method as basic EPS, but reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock. For a further discussion of Chase's earnings per share computation, see Note Ten of Chase's 1997 Annual Report.
