(1): The ratio of earnings to fixed charges is computed by dividing loss before taxes plus fixed charges by fixed charges. Fixed charges consist of interest expense (including interest expense from capital leases) and the estimated portion of rental expense deemed by us to be representative of the interest factor of rental payments under operating leases, plus amortization of debt issuance expenses. Earnings were insufficient to cover fixed charges by $86.9 million, $178.9 million, $211.9 million, $31.8 million and $186.3 million or the years ended December 31, 2007, 2008, 2009, 2010 and 2011 respectively.
(2): NM—Not meaningful.
