Ratio of earnings to fixed charges(1)

    6.3 x   4.5 x   10.4 x                
                               

(1)
For the purpose of calculating such ratios, "earnings" consist of income from continuing operations before income taxes, equity in net losses of equity method investees 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 $184 million and $1,622 million for the fiscal years ended August 30, 2007 and August 28, 2008, respectively and by $1,029 million and $1,504 million for the first six months ended February 28, 2008 and March 5, 2009, respectively.
