         undistributed earnings or recognized losses of partially-owned
         affiliates which are less than 50% owned, minority interests in net
         earnings of subsidiaries, and amortization of  previously capitalized
         interest), plus (b) fixed charges, minus (c) interest capitalized
         during the period.  "Fixed charges" consist of (a) interest incurred
         and amortization of debt expense plus (b) the portion of rent expense
         representative of the interest factor.
