Statements Regarding Computations of Ratios of Earnings to Fixed Charges

        The following table sets forth the ratio of earnings to fixed charges for our company and our subsidiaries for each of the periods indicated. We calculated the ratio of earnings to fixed charges by dividing earnings by total fixed charges. Earnings consist of pretax income plus fixed charges. Fixed charges are defined as the sum of interest expensed plus amortized capitalized expenses related to indebtedness plus an estimate of the interest within rental expense.
