          For the purpose of computing this ratio, "earnings" consist of (a)
          income from continuing operations before income taxes (adjusted for
          undistributed earnings or recognized losses of partially-owned
          affiliates, minority interest in earnings or losses of consolidated
          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.
