For the purpose of calculating the ratio of earnings to fixed charges, earnings consist of our income (loss) before provision for income taxes plus our fixed charges. Fixed charges consist of interest expense, amortization of debt discount and debt issuance costs and an estimate of the interest portion of rental expense. Interest expense recorded on uncertain tax positions has been recorded in the provision for income taxes and therefore has been excluded from the calculation.

(a) In fiscal 2013, 2012, 2010 and, 2009 we incurred losses from pre-tax continuing operations, and as a result, our earnings were insufficient to cover our fixed charges by $1.19 billion, $61.5 million, $55.0 million and, $2.15 billion, respectively.
