|(1) | Ratio of earnings to fixed charges is computed by dividing earnings by fixed charges. For purposes of this calculation, earnings is income before income
taxes plus fixed charges less capitalized interest. Fixed charges is interest expense plus capitalized interest. This calculation is different from the fixed charge coverage ratio as defined in the footnotes to the financial statements.
