For purposes of computing the ratio of earnings to combined fixed charges and
preferred dividend requirements, "earnings" consists of income before cumulative
effect of a change in accounting principle plus fixed charges and income taxes,
less undistributed income for equity investees. "Fixed charges" consists of
interest charges, the amortization of debt discounts and issue costs and the
representative interest portion of operating leases.  "Preferred dividend
requirements" consists of the pre-tax preferred dividend requirement.
