For the purpose of calculating such ratios, "earnings" consist of income from continuing operations before income taxes and noncontrolling interests plus fixed charges and "fixed charges" consist of interest expense (net of capitalized portion), capitalized interest, amortization of debt discount and the portion of rental expense representative of interest expense. Earnings before fixed charges were inadequate to cover total fixed charges by $1,008 million and $1,202 million for the fiscal years ended August 29, 2002 and August 28, 2003, respectively.
