Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES The Company determines income taxes using the asset and liability method, which results in the recognition of deferred tax assets and liabilities. These assets and liabilities reflect the expected future tax consequences of temporary differences between the carrying amount and the tax basis of those assets and liabilities, as well as operating loss and tax credit carryforwards, using enacted tax rates in effect in the years in which the differences are expected to reverse. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Deferred tax assets and liabilities are recorded on a jurisdictional basis. At September 30, 2015, the Company has approximately $104.8 million of regular federal tax net operating loss carryforwards in the U.S. expiring from 2020 through 2028. Usage of $80.9 million of these net operating losses is limited to approximately $10.2 million annually as a result of the change in control of the Company that occurred in connection with the Norilsk Nickel transaction in 2003. The Company has $31.6 million of alternative minimum tax credit carryforwards which will not expire and $1.6 million in general business credits expiring during 2029 to 2034. The Company has approximately $3.3 million of state tax net operating loss carryforwards expiring during 2020 through 2029. The Company also has $51.6 million of foreign net operating loss carryforwards. The foreign net operating losses expire as follows: $18.1 million during 2016 to 2019 and $25.4 million during 2024 to 2035. Currently, $8.1 million of foreign net operating losses have an indefinite life. In assessing the realizability of deferred tax assets, the Company considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The Company considers the scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies in making this assessment. The Company has a valuation allowance in 2015 and 2014 to reflect the estimated amount of deferred tax assets which may not be realized, which principally relate to foreign and state net operating losses, capital losses, and certain tax credits. The provision for income taxes for the three- and nine-month periods ended September 30, 2015 consists of U.S. Federal income tax, state tax, as well as deferred tax benefits from certain foreign jurisdictions. Changes in the Company’s net deferred tax assets and liabilities have been partially offset by a corresponding change in the valuation allowance. The Company recognized an income tax benefit / (provision) for the three-month periods ended September 30, 2015 and 2014, of $2.5 million and $(5.6) million, respectively. The Company recognized an income tax benefit / (provision) for the nine-month periods ended September 30, 2015 and 2014, of $8.1 million and $(15.9) million, respectively. The partial restructure of internal operations and the creation of a separate metal sales and trading subsidiary is primarily responsible for a discrete income tax benefit of $10.6 million recognized for the nine-month period ending September 30, 2015. Of this discrete income tax benefit, $8.3 million is associated with the partial restructure results from a re-measuring of the Company’s deferred state tax associated with deferred tax assets and liabilities from a blended deferred rate of 10.6% at December 31, 2014 to 4.0% at September 30, 2015. The Company’s policy is to recognize interest and penalties on unrecognized tax benefits in Income tax benefit (provision) in the Company's Consolidated Statements of Comprehensive (Loss) Income. The Company does not have any uncertain benefits at September 30, 2015. There were no interest or penalties accrued at September 30, 2015 and for the comparable period in 2014, interest and penalties accrued were $0.8 million. The Company made income tax payments of $13.1 million and $14.2 million in the nine-month periods ended September 30, 2015 and 2014, respectively. Tax years still open for examination by the taxing authorities are the years ended December 31, 2014, 2013, 2012 and 2011, although net operating loss and credit carryforwards from all years are subject to examination and adjustment for the three years following the year in which the carryforwards are utilized.
