           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.
