When we calculate our ratio of earnings to fixed charges, “earnings” are composed of the following:

•	consolidated earnings or loss from continuing operations before tax, excluding undistributed equity earnings or affiliated companies; plus
•	fixed charges, excluding capitalized interest.
Fixed charges are comprised of the following:
•	interest expense on indebtedness and capitalized interest;
•	amortization of debt issuance costs, discounts and premiums; and
•	the portion of capitalized leases deemed to be representative of interest.
