For purposes of calculating the ratio of consolidated earnings to fixed charges:

“earnings” is the aggregate of the following items: pre-tax income or loss from continuing operations before adjustment for income or loss from equity investees; plus fixed charges; plus amortization of capitalized interest; less capitalized interest and noncontrolling interest in pre-tax income of subsidiaries that have not incurred fixed charges; and

“fixed charges” means the sum of the following: interest expensed and capitalized; amortized premiums, discounts and capitalized expenses related to indebtedness; and an estimate of the interest within rental expense. Fixed charges are not reduced by any allowance for funds used during construction.
