For purposes of computing the ratio of earnings to fixed charges, "earnings"
consists of income before cumulative effect of a change in accounting principle
plus fixed charges and income taxes, less undistributed income from equity
investees. "Fixed charges" consists of interest charges, the amortization of
debt discounts and issue costs and the representative interest portion of
operating leases.
