EXHIBIT 12.2

RATIO OF COMBINED FIXED CHARGES AND PREFERENCE DIVIDENDS TO EARNINGS

     We have computed the ratio of combined fixed charges and preference dividends to earnings for each of the following periods on a consolidated basis. “Earnings” consist of pretax income (loss) before adjustment for minority interests in consolidated subsidiaries or income or loss from equity investees plus fixed charges (excluding capitalized interest) plus distributed income or equity investees. “Fixed charges” represent interest incurred (whether expensed or capitalized), amortization of debt expense and an estimate of the interest within rent expense. “Preference Dividends” represent the amount of pre-tax earnings that is required to pay dividends on outstanding preference securities. You should read the ratio of combined fixed charges and preference dividends to earnings in conjunction with our consolidated and condensed financial statements that are incorporated by reference in this prospectus.
