Income Tax Disclosure [Abstract]
Income Taxes	The effective tax rate on continuing operations was a negative 1.3 percent and a negative 31.4 percent for the three months ended March 31, 2016 and 2015, respectively. There is no tax benefit or expense for discrete items for the three months ended March 31, 2016. Tax expense for the three months ended March 31, 2016 was $0.2 million, due to Canadian Tax and the Texas Margins Tax. The Company has reserved for the benefit of current year losses in the United States. As of March 31, 2016, U.S. federal and state deferred tax assets continue to be covered by valuation allowances. The ultimate realization of deferred tax assets is dependent upon the generation of future U.S. taxable income. The Company considers the impacts of reversing taxable temporary differences, future forecasted income and available tax planning strategies when evaluating whether deferred tax assets are more likely than not to be realized. The Company's interim tax provision has been estimated using the discrete method, which was based on statutory tax rates applied to pre-tax income as adjusted for permanent differences such as transfer pricing differences between generally accepted accounting principles and local country tax. The Company believes that this method yields a more reliable income tax calculation for interim periods. It is reasonably possible the unrecognized tax benefits may change between $0.0 million to $3.0 million within the next twelve months as a result of settling tax examinations related to 2008-2011.
