The ratio of earnings to fixed charges represents the number of times fixed charges are covered by earnings. For purposes of computing this ratio, earnings consist of profit from operations before taxes and share of results of associates, plus fixed charges, minus interest capitalized during the period. Fixed charges consist of interest and accretion expense, interest on finance lease obligations, interest capitalized, plus one-third of rent expense on operating leases, estimated by us as representative of the interest factor attributable to such rent expense.

We did not have any preferred stock outstanding and did not pay or accrue any preferred stock dividends during the periods presented above.
