Note:
Basic 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. The computation provides for the
elimination of related convertible debenture interest and preferred
dividends.
