For the purpose of calculating the ratio of earnings to fixed charges, earnings consist of net income plus the provision for income taxes and 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 2009 and 2008, we incurred losses from operations, and as a result, our earnings were insufficient to cover our fixed charges by $2.15 billion and $327.8 million, respectively. |
