The computation of the ratio of earnings to fixed charges is based on applicable amounts of the Company plus dividends received from unconsolidated affiliates. “Earnings” consist of income before income taxes, the cumulative effect of changes in accounting and fixed charges excluding unamortized capitalized interest.  “Fixed charges” consist of interest on indebtedness, amortization of debt discount and expense, interest related to uncertain tax positions, an estimated amount of rental expense that is deemed to be representative of the interest factor, and capitalized interest.

 

The Company has not issued preferred stock. Therefore, the ratios of earnings to combined fixed charges and preferred stock dividends are the same as the ratios presented above.
