Exhibit 12.1

RATIO OF EARNINGS TO FIXED CHARGES

     The ratio was computed by dividing earnings by fixed charges. For this purpose, “earnings” represent the aggregate of pre-tax income from continuing operations before adjustment for minority interests in consolidated subsidiaries or income or loss from equity investees, amortization of capitalized interest, distributed income of equity investees, our share of pre-tax losses of equity investees, and fixed charges less capitalized interest. The table below sets forth our consolidated ratios of earnings to fixed charges for the periods indicated.
