^* Earnings are inadequate to cover fixed charges in these periods.

For purposes of computing the ratio of earnings to fixed charges, fixed charges consist of interest expense on long-term debt and capital leases, amortization of deferred financing costs and that portion of rental expense deemed to be representative of interest. Earnings consist of income (loss) before income taxes, minority interest, and equity in net loss of Spansion Inc. and other plus fixed charges. For the fiscal year ended 2006, earnings were insufficient to cover fixed charges by $74 million. For the quarter ended March 31, 2007, earnings were insufficient to cover fixed charges by $568 million.
