| Income Taxes                         | Income TaxesAt September 30, 2013, the Company had a federal net operating loss carryforward of $85.2 million and a state net operating loss carryforward of $601.4 million. At December 31, 2012, the Company had a federal net operating loss carryforward of $83.5 million and a state net operating loss carryforward of $596.8 million. These net operating losses are available to offset future taxable income through 2031.In general, a valuation allowance is recorded if, based on the weight of available evidence, it is more likely than not that some portion or all of the deferred tax asset will not be realized. Realization of the Company’s deferred tax assets is dependent upon the Company generating sufficient taxable income in future years in the appropriate tax jurisdictions to obtain a benefit from the reversal of deductible temporary differences and from loss carryforwards. Based on the timing of reversal of future taxable amounts and the Company’s recent history of losses and potential future expectations of reporting taxable losses, management does not believe it met the requirements to realize the benefits of certain of its deferred tax assets, therefore the Company has maintained a valuation allowance. During the nine month period ended September 30, 2013, the valuation allowance has decreased by $1.5 million. The valuation allowance was $91.1 million at September 30, 2013 and $92.6 million at December 31, 2012.The valuation allowance to offset the deferred tax component recognized in Accumulated other comprehensive loss was $2.8 million and $3.3 million at September 30, 2013 and December 31, 2012, respectively. |
