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.
