Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Income tax expense was immaterial for the three months ended September 30, 2012 and 2011. Income tax expense for the nine months ended September 30, 2012 was $0.4 million and for the nine months ended September 30, 2011 was $0.2 million. The difference in effective tax rate of 16.8% for the nine months ended September 30, 2012 and 13.0% for the year ended December 31, 2011 is primarily due to increased profitability in the U.S. which has resulted in increases in both Federal and state taxes. Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the carrying amounts of existing assets and liabilities in the financial statements and their respective tax bases using tax rates expected to be in effect during the years in which the basis differences reverse. In assessing the ability to realize deferred tax assets, the Company's management considers whether it is more likely than not that some portion or all of a deferred tax asset will be realized. The ultimate realization of deferred tax assets is dependent upon the generation of sufficient future taxable income during the periods in which those temporary differences become deductible. A valuation allowance is recorded for loss carryforwards and other deferred tax assets where it is more likely than not that such deferred tax assets will not be realized. The Company believes it is more likely than not that it would not be able to utilize these deferred tax assets in the future and as a result the Company has recorded a full valuation allowance on the U.S. federal and state deferred tax assets through September 30, 2012. The Company continues to review its conclusions about the appropriate amount of its deferred income tax asset valuation allowance in light of circumstances existing in current periods and considering the expected future period results. In the future, if the Company determines based on its current and expected future profitability that these deferred tax assets are more likely than not to be realized, a release of all or part of the related valuation allowance could result in an immediate material income tax benefit in the period of adjustment and material income tax provisions in periods beyond this adjustment. Such release of the valuation allowance could occur in the foreseeable future provided the Company results continue to remain positive. As of September 30, 2012, there were no material changes to either the nature or the amounts of the uncertain tax positions previously determined for the year ended December 31, 2011.
