| (1) | The ratio of earnings to fixed charges is computed by dividing the sum of earnings before income taxes and fixed charges by fixed charges. Fixed charges represent interest expense (before interest is capitalized), amortization of debt premiums and discounts, capitalized expenses related to indebtedness and an appropriate interest factor on operating leases. Fixed charges represent amounts relating to continuing operations. |
