For purposes of calculating the ratio of earnings to fixed charges, earnings are the amount resulting from adding (a) pretax income from continuing operations, (b) fixed charges, (c) minority interests in consolidated subsidiaries, and (d) cash distributions from equity method investments; and subtracting (e) income (loss) from equity method investments. Fixed charges consist of (a) interest expense inclusive of amortized premiums, discounts and capitalized expenses related to indebtedness and (b) the portion of rental expense deemed representative of interest expense (estimated to be one-third of rental expense). Interest associated with our uncertain tax positions is a component of income tax expense and not fixed charges.
