Note: Earnings consist of earnings before income taxes and fixed charges
      after eliminating undistributed earnings (losses) of affiliates and
      capitalized interest net of amortization of previously capitalized
      interest.  Fixed charges consist of interest expense, including
      capitalized interest, and amortization of debt discount and expense on
      all indebtedness, plus one-third of rent expense deemed to represent an
      interest factor.
