Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	BASIS OF PRESENTATION The unaudited condensed consolidated financial statements of Centrus Energy Corp. (“Centrus” or the “Company”), which include the accounts of the Company, its principal subsidiary United States Enrichment Corporation (“Enrichment Corp.”) and its other subsidiaries, as of and for the three and six months ended June 30, 2015 and 2014 have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). The unaudited condensed consolidated financial statements reflect all adjustments that are, in the opinion of management, necessary for a fair statement of the financial results for the interim period. Certain information and notes normally included in financial statements prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) have been omitted pursuant to such rules and regulations. All material intercompany transactions have been eliminated. Operating results for the three and six months ended June 30, 2015 are not necessarily indicative of the results that may be expected for the year ending December 31, 2015. The unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes and Management's Discussion and Analysis of Financial Condition and Results of Operations included in the Annual Report on Form 10-K for the year ended December 31, 2014. On March 5, 2014, USEC Inc. filed a voluntary petition for relief (the “Bankruptcy Filing”) under Chapter 11 of Title 11 of the United States Code (the “Bankruptcy Code”) in the United States Bankruptcy Court for the District of Delaware (the “Bankruptcy Court”). The Bankruptcy Filing was “pre-arranged” and included the filing of a proposed Plan of Reorganization (the “Plan of Reorganization”) supported by certain holders of the claims and interests impaired under the Plan of Reorganization. On August 18, 2014, the Company announced that the Plan of Reorganization was accepted by more than 99% in both value and number of votes cast of holders of its convertible notes and that both holders of the Company’s preferred equity voted in favor of the Plan of Reorganization. On September 5, 2014, the Bankruptcy Court entered an order approving and confirming the Plan of Reorganization. On September 30, 2014 (the “Effective Date”), the Company satisfied the conditions of the Plan of Reorganization and the Plan of Reorganization became effective. On the Effective Date, USEC Inc.’s name was changed to Centrus Energy Corp. In accordance with Accounting Standards Codification Topic 852, Reorganizations, Centrus adopted fresh start accounting upon emergence from Chapter 11 bankruptcy resulting in Centrus becoming a new entity for financial reporting purposes. References to “Successor” or “Successor Company” relate to the financial position of the reorganized Centrus as of and subsequent to September 30, 2014 and results of operations subsequent to September 30, 2014. References to “Predecessor” or “Predecessor Company” relate to the Company prior to September 30, 2014. As a result of the application of fresh start accounting and the effects of the implementation of the Plan of Reorganization, the consolidated financial statements on or after September 30, 2014 are not comparable to consolidated financial statements prior to that date. Expenses, gains and losses directly associated with reorganization proceedings are reported as Reorganization Items, Net, in the accompanying condensed consolidated statement of operations. New Accounting Standards In May 2014, the Financial Accounting Standards Board (“FASB”) issued comprehensive new guidance for revenue recognition. The core principle of the new standard is that revenue should be recognized when an entity transfers promised goods or services to customers in an amount that reflects the consideration the entity expects to receive in exchange for those goods or services. The new standard will supersede current guidance in effect and may require the use of more judgment and estimates, including estimating the amount of variable revenue to recognize over each identified performance obligation. The new standard requires additional disclosures to describe the nature, amount and timing of revenue and cash flows arising from contracts. In July 2015, the FASB deferred the effective date of the new revenue recognition standard by one year. The new standard will become effective for Centrus beginning with the first quarter of 2018 and can be adopted either retrospectively to each prior reporting period presented or as a cumulative effect adjustment as of the date of adoption. Centrus is evaluating the impact of adopting this new guidance on its consolidated financial statements. In April 2015, the FASB issued guidance to simplify the presentation of debt issuance costs. The new guidance requires the presentation of debt issuance costs in the balance sheet as a deduction from the carrying amount of the related debt liability instead of a deferred charge asset. Debt disclosures will include the face amount of the debt liability and the effective interest rate. The new guidance requires retrospective application and is effective for Centrus beginning with the first quarter of 2016. Early adoption is permitted. Centrus is evaluating the impact of adopting this new guidance on its consolidated financial statements. In May 2015, the FASB issued guidance to eliminate the requirement to categorize investments in the fair value hierarchy table for which the fair value is measured at net asset value (“NAV”) per share as a practical expedient. The new guidance requires retrospective application and is effective for Centrus beginning in the first quarter of 2016. Earlier adoption is permitted. Centrus adopted in the current quarter and no longer categorizes money market funds in the fair value hierarchy table in Note 9. The Company’s investments in money market funds are included in cash and cash equivalents in the consolidated balance sheet. The new guidance only impacts the Company’s fair value measurement disclosures and did not affect the Company’s financial condition, results of operations, or cash flows. In July 2015, the FASB issued guidance that simplifies the subsequent measurement of inventories by replacing the current valuation test (lower of cost or market) with a lower of cost or net realizable value (“NRV”) test. The new test is applicable for certain inventory costing methods including the monthly moving average cost method used by Centrus. NRV is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. Under former guidance, NRV was one of several determinations used to assess market values. The new guidance is effective for Centrus beginning in the first quarter of 2017 and earlier adoption is permitted. Under current guidance, NRV has been the determining factor in assessing the market value for the Company’s principal inventory, the separative work unit (“SWU”) component of low enriched uranium (“LEU”). The Company does not expect the adoption of the new guidance will have a material effect on the Company’s financial condition, results of operations, or cash flows.
