      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.
