For purposes of computing the ratio of earnings to combined fixed charges and
preferred stock 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.
