| The computation of the ratio of earnings to fixed charges is based on applicable amounts of the Company and its consolidated subsidiaries plus dividends received from unconsolidated affiliates. “Earnings” consist of income before income taxes, the cumulative effect of changes in accounting, discontinued operations 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.
* | Income of consolidated group before income taxes, total earnings and ratio of earnings to fixed charges has been adjusted, if applicable, for prior periods for the adoption of ASC 810, Consolidation (FASB Statement No. 160, Noncontrolling Interests in Consolidated Financial Statements).
