(1): The preceding table sets forth our historical ratios of earnings to fixed charges and preferred stock dividends for the periods indicated. This information should be read in conjunction with the consolidated financial statements and the accompanying notes incorporated by reference in this prospectus. During the periods indicated, we had no outstanding shares of preferred stock. Accordingly, our historical ratio of earnings to fixed charges and preferred stock dividends is the same as our ratio of earnings to fixed charges in all periods.
(2): Earnings available for fixed charges consist of earnings from continuing operations before income taxes and fixed charges excluding capitalized interest, net of amortization, reduced by undistributed earnings of our less than 50% owned affiliates.
(3): Fixed charges consist of interest expense, amortization of debt discount and expenses and capitalized interest, plus that portion of rental expense estimated to be the equivalent of interest.
