(A) Antidilutive

      Note:
            Earnings per common share was computed by dividing net income,
            reduced by preferred stock dividend requirements, by the weighted
            average of the number of shares of common stock outstanding during
            each period. Diluted earnings per common share was computed on the
            assumption that all convertible debentures, convertible preferred
            stock, and stock options converted or exercised during each period,
            or outstanding at the end of each period were converted at the
            beginning of each period or the date of issuance or grant, if
            dilutive. This computation provides for the elimination of related
            convertible debenture interest and preferred dividends.
