Earnings per common share, assuming full dilution, were 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 at the date of issuance or grant, if dilutive. This computation provides for the elimination of related convertible debenture interest and preferred dividends.
