EXHIBIT 12

COMPUTATION OF RATIO OF EARNINGS TO FIXED CHARGES

The ratio of earnings to fixed charges, the ratio of earnings to combined fixed charges and preferred stock dividends, as well as any deficiency of earnings are determined using the following applicable factors:

Earnings available for fixed charges are calculated first, by determining the sum of: (a) income from continuing operations before income taxes and equity income; (b) distributed equity income; (c) fixed charges, as defined below; and (d) amortization of capitalized interest, if any. From this total, we subtract capitalized interest and net income attributable to noncontrolling interests.

Fixed chargesare calculated as the sum of: (a) interest costs (both expensed and capitalized); (b) amortization of debt expense and discount or premium relating to any indebtedness; and (c) that portion of rental expense that is representative of the interest factor.

Preferred stock dividends used in the ratio of earnings to combined fixed charges and preferred stock dividends consist of the amount of pre-tax earnings required to cover dividends paid on our Series A convertible preferred stock.
