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 nine months ended September 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. Certain amounts have been reclassified to conform to the current presentation. Operating results for the three and nine months ended September 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 August 2015, the FASB issued guidance deferring 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 August 2014, the FASB issued guidance requiring management to assess an entity’s ability to continue as a going concern, and to provide related disclosures in certain circumstances. The new standard is effective for annual periods beginning after December 15, 2016, and for annual and interim periods thereafter. Early adoption is permitted. The implementation of the new standard is not expected to have a material impact on Centrus' 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 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.

Transition Charges

Transition Charges	9 Months Ended
	Sep. 30, 2015
Restructuring and Related Activities [Abstract]
Transition Charges	TRANSITION CHARGES Direct Charges The Company ceased uranium enrichment at the Paducah Gaseous Diffusion Plant (the “Paducah GDP”) at the end of May 2013 and subsequently completed transferring its inventory to off-site licensed locations to meet future customer orders. On October 21, 2014, all of the leased portions of the Paducah GDP were de-leased and returned to the U.S. Department of Energy (“DOE”). Pursuant to a June 2014 agreement with DOE, the lease terminated with respect to the Paducah GDP on August 1, 2015. The termination of the lease with respect to the Paducah GDP does not affect the Company’s right to lease portions of the DOE-owned site in Piketon, Ohio needed for the American Centrifuge program. The USEC Privatization Act and the lease for the plant provide that DOE remains responsible for decontamination and decommissioning of the Paducah GDP site. Since ceasing uranium enrichment at the Paducah GDP in May 2013, the Company has incurred a number of expenses unrelated to production that have been charged directly to cost of sales. Direct charges totaled $23.9 million and $32.5 million in the three and nine months ended September 30, 2015 and $17.5 million and $66.7 million in the corresponding periods in 2014 as follows: - Lump-sum pension payments to former employees in the first nine months of 2015 resulted in the remeasurement of pension obligations under the Retirement Program Plan for Employees of United States Enrichment Corporation and direct charges to cost of sales of $21.6 million in both the three and nine months ended September 30, 2015; - Operating expenses of $2.3 million and $10.6 million in the three and nine months ended September 30, 2015, compared to $15.6 million and $51.3 million in the corresponding periods in 2014. Charges in 2015 include off-site inventory management and logistics costs. Charges in 2014 include inventory management and disposition, ongoing regulatory compliance, utility requirements for operations, security, and other Paducah site management activities related to the transitioning of facilities and infrastructure to DOE; - Inventory charges of $0 and $0.3 million in the three and nine months ended September 30, 2015, compared to $1.8 million and $13.5 million in the three and nine months ended September 30, 2014, including the cost of inventories deployed for cascade drawdown, assay blending and repackaging, and residual uranium in cylinders transferred to DOE. The Company determined that it was uneconomic to recover resulting residual quantities for resale; and - Asset depreciation charges of $0.1 million and $1.9 million in the three and nine months ended September 30, 2014. Paducah GDP asset depreciation was completed as of June 30, 2014. Special Charges for Workforce Reductions Centrus notified its American Centrifuge employees in September 2015 of possible layoffs beginning in November 2015 as a result of DOE’s decision to reduce funding for advanced uranium enrichment centrifuge research under the Company’s contract with Oak Ridge National Laboratory (“ORNL”). Based on the level of funding reduction, Centrus incurred a special charge of $8.7 million in the third quarter of 2015 for estimated termination benefits consisting primarily of payments under its severance plan. Centrus expects to make payments for these workforce reductions over the next 18 months. Additional details are provided in Note 13 under American Centrifuge - Project Funding . In addition, the cessation of enrichment at the Paducah GDP and evolving business needs have resulted in workforce reductions since July 2013. In the three and nine months ended September 30, 2015, special charges included related termination benefits of $1.1 million and $4.9 million , respectively, less $0.3 million in the nine-month period for severance paid by the Company and invoiced to DOE for its share of employee severance pursuant to the USEC Privatization Act. A summary of special charges and changes in the related balance sheet accounts in the nine months ended September 30, 2015 follows (in millions): Liability Balance to Be Paid, Dec. 31, 2014 Nine Months Ended September 30, 2015 Liability Balance to Be Paid, Sep. 30, 2015 Special Charges Paid Workforce reductions, primarily severance payments $ 2.4 $ 13.6 $ (6.7 ) $ 9.3 Less: Amounts billed to DOE (0.3 ) Special charges for workforce reductions $ 13.3

Research and Development [Abstract]
Advanced Technology Costs and Other Income	ADVANCED TECHNOLOGY COSTS AND OTHER INCOME From June 2012 through April 2014, the Company performed work under the June 2012 cooperative agreement with DOE (the “Cooperative Agreement”) for the American Centrifuge technology with DOE providing cost-share funding for up to 80% for a total government cost share of $280 million . The Cooperative Agreement expired in accordance with its terms on April 30, 2014. For the three and nine months ended September 30, 2014, advanced technology costs included costs for work performed under the Cooperative Agreement and DOE’s cost share was recognized as other income. On May 1, 2014, the Company signed an agreement for continued research, development and demonstration of the American Centrifuge technology in furtherance of DOE’s national security objectives (the “American Centrifuge Technology Demonstration and Operations Agreement”, or “ACTDO Agreement”) with UT-Battelle, LLC (“UT-Battelle”), the management and operating contractor for ORNL. Revenue and cost of sales for work that Centrus performed under the fixed-price ACTDO Agreement as a subcontractor to UT-Battelle are reported in the contract services segment. Refer to Note 13, Commitments and Contingencies - American Centrifuge , regarding the status of project funding after September 2015. American Centrifuge costs incurred by the Company that are outside of the ACTDO Agreement are included in advanced technology costs, including certain demobilization and maintenance costs. Such costs totaled $1.9 million in the three months and $7.7 million in the nine months ended September 30, 2015, and $5.3 million in the three months and $12.3 million in the nine months ended September 30, 2014.

Certain overdue receivables from DOE are included in other long-term assets based on the extended timeframe expected to resolve claims for payment. The Company has filed claims with DOE for payment under the Contract Disputes Act (“CDA”). Unpaid invoices to DOE related to filed claims totaled approximately $75 million as of September 30, 2015 and December 31, 2014. Due to the lack of a resolution with DOE and uncertainty regarding the timing and amount of future collections, the long-term receivable for accounting purposes is $19.5 million as of September 30, 2015 and $19.9 million as of December 31, 2014. Centrus has unapplied payments from DOE that may be used, at DOE’s direction, (a) to pay for future services provided by the Company or (b) to reduce outstanding receivables balances due from DOE. The payments balance of $19.5 million as of September 30, 2015 and $19.6 million as of December 31, 2014 is included in other long-term liabilities pending resolution of the long-term receivables from DOE described above.

Centrus exchanged SWU for uranium under a barter contract in the three months ended September 30, 2015. SWU revenue of $8.8 million was recognized based on the fair market value of the uranium received in exchange for SWU delivered. Uranium Provided by Customers and Suppliers Centrus held uranium with estimated values of approximately $0.5 billion as of September 30, 2015 and $0.6 billion as of December 31, 2014 to which title was held by customers and suppliers and for which no assets or liabilities were recorded on the balance sheet. While in some cases Centrus sells both the SWU and uranium components of LEU to customers, utility customers typically provide uranium to Centrus as part of their enrichment contracts. Title to uranium provided by customers generally remains with the customer until delivery of LEU at which time title to LEU is transferred to the customer, and title to uranium is transferred to Centrus.

Intangible Assets	INTANGIBLE ASSETS Intangible assets represent the fair value adjustment to the assets and liabilities for the Company’s LEU segment resulting from the Company’s reorganization and application of fresh start accounting as of September 30, 2014. The amortizable intangible assets relate to backlog and customer relationships. The excess of the reorganization value over the fair value of identified tangible and intangible assets is reported separately on the condensed consolidated balance sheet. The backlog intangible asset is amortized as backlog valued at emergence is reduced, principally as a result of deliveries to customers. The customer relationships intangible asset is amortized using the straight-line method over the estimated average useful life of 15 years. Amortization expense is presented below gross profit on the condensed consolidated statement of operations.

Debt Disclosure [Abstract]
Debt	DEBT On the Effective Date and pursuant to the Plan of Reorganization, all of the Company’s convertible senior notes that were issued and outstanding immediately prior to the Effective Date were cancelled and the Company issued 8.0% paid-in-kind toggle notes (the “PIK Toggle Notes”) pursuant to the Indenture. The PIK Toggle Notes were issued in an initial aggregate principal amount of $240.4 million . No cash was received related to the issuance. The principal amount may be increased by any payment of interest in the form of PIK payments, as elected by the Company. The PIK Toggle Notes pay interest at a rate of 8.0% per annum. Interest is payable semi-annually in arrears based on a 360-day year consisting of twelve 30-day months. The Company elected to pay 3.0% per annum of interest due on the PIK Toggle Notes for the semi-annual interest periods ending on March 31, 2015 and September 30, 2015 in the form of PIK payments. As such, interest for the twelve months ended September 30, 2015 was paid as $12.0 million in cash and $7.2 million in PIK payments, and the principal balance increased accordingly to $247.6 million . For any interest payment date from October 1, 2015 through the maturity of the PIK Toggle Notes, the Company has the option to pay up to 5.5% per annum of interest due on the PIK Toggle Notes in the form of PIK payments. For the semi-annual interest period ending March 31, 2016, the Company has elected to pay interest in the form of PIK payments at 5.5% per annum. The PIK Toggle Notes will mature on September 30, 2019. However, the maturity date can be extended to September 30, 2024 upon the satisfaction of certain funding conditions described in the Indenture relating to the funding, under binding agreements, of (i) the American Centrifuge project or (ii) the implementation and deployment of a National Security Train Program utilizing American Centrifuge technology. The PIK Toggle Notes rank equally in right of payment with all existing and future unsubordinated indebtedness of the Company (other than the Issuer Senior Debt as defined below) and are senior in right of payment to all existing and future subordinated indebtedness of the Company. The PIK Toggle Notes are subordinated in right of payment to certain indebtedness and obligations of the Company described in the Indenture (the “Issuer Senior Debt”), including (i) any indebtedness of the Company under a future credit facility, (ii) obligations of, and claims against, the Company under any equity investment (or any commitment to make an equity investment) with respect to the financing of the American Centrifuge project, (iii) obligations of, and claims against, the Company under any arrangement with DOE, export credit agencies or any other lenders or insurers with respect to the financing or government support of the American Centrifuge project and (iv) indebtedness of the Company to Enrichment Corp. under the Centrus Intercompany Note. The PIK Toggle Notes are guaranteed and secured on a subordinated and limited basis by Enrichment Corp. The Enrichment Corp. guarantee ranks equally in right of payment with all existing and future unsubordinated indebtedness of Enrichment Corp. (other than the Designated Senior Claims as defined below) and is senior in right of payment to all existing and future subordinated indebtedness of Enrichment Corp. The Enrichment Corp. guarantee is subordinated in right of payment to certain obligations of, and claims against, Enrichment Corp. described in the Indenture (collectively, the "Designated Senior Claims"), including obligations and claims: • under a future credit facility; • held by or for the benefit of the Pension Benefit Guaranty Corporation ("PBGC") pursuant to any settlement of any actual or alleged ERISA Section 4062(e) event; • held by any party with respect to any equity investment (or any commitment to make an equity investment) with respect to the financing of the American Centrifuge project; • held by DOE, export credit agencies or any other lenders or insurers with respect to the financing or government support of the American Centrifuge project; and • held by the U.S. government. The Company incurred offering expenses of $0.7 million related to the issuance of the PIK Toggle Notes. These costs are deferred and are being amortized on a straight-line basis, which approximates the effective interest method, over the life of the PIK Toggle Notes. The deferred financing cost balance, included in other long-term assets, was $0.6 million at September 30, 2015.

Fair Value Disclosures [Abstract]
Fair Value Measurements	FAIR VALUE MEASUREMENTS Pursuant to the accounting guidance for fair value measurements, fair value is defined as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required or permitted to be recorded at fair value, consideration is given to the principal or most advantageous market and assumptions that market participants would use when pricing the asset or liability. The accounting guidance establishes a fair value hierarchy based on the level of independent, objective evidence surrounding the inputs used to measure fair value: • Level 1 – quoted prices in active markets for identical assets or liabilities. • Level 2 – inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices in active markets for similar assets or liabilities, quoted prices for identical or similar assets or liabilities in markets that are not active, or model-derived valuations in which significant inputs are observable or can be derived principally from, or corroborated by, observable market data. • Level 3 – unobservable inputs in which little or no market data exists. Financial Instruments Recorded at Fair Value (in Millions) September 30, 2015 December 31, 2014 Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Total Assets: Money market funds (a) $ 170.2 — — $ 170.2 $ 212.2 — — $ 212.2 Deferred compensation asset (b) — $ 1.4 — $ 1.4 — $ 3.2 — $ 3.2 Liabilities: Deferred compensation obligation (b) — 1.2 — 1.2 — 3.0 — 3.0 (a) Included in cash and cash equivalents. (b) The deferred compensation obligation represents the balance of deferred compensation plus net investment earnings. The deferred compensation plan is informally funded through a rabbi trust using variable universal life insurance. The cash surrender value of the life insurance policies is designed to track the deemed investments of the plan participants. Investment crediting options consist of institutional and retail investment funds. The deemed investments are classified within Level 2 of the valuation hierarchy because (i) of the indirect method of investing and (ii) unit prices of institutional funds are not quoted in active markets. There have been no transfers between Levels 1, 2 or 3 during the periods presented. Other Financial Instruments As of September 30, 2015 and December 31, 2014, the balance sheet carrying amounts for cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities (excluding the deferred compensation obligation described above), and payables under SWU purchase agreements approximate fair value because of the short-term nature of the instruments. The estimated fair value of the PIK Toggle Notes was $75.8 million at September 30, 2015 and $121.2 million at December 31, 2014 based on the most recent trading prices as of the balance sheet date (Level 1).

The Company does not expect there to be a required contribution for the qualified defined benefit pension plans in 2015, and therefore, does not expect to contribute in 2015. There is no required contribution for the postretirement health and life benefit plans under Employee Retirement Income Security Act (“ERISA”), and the Company does not expect to contribute in 2015. Lump-sum pension payments of $49.1 million in the first nine months of 2015 to former employees, including those affected by workforce reductions, resulted in the remeasurement of pension obligations under settlement accounting rules. The interim remeasurements were required when the payments exceeded the sum of the service cost and interest cost components of the annual net periodic benefit cost for each plan for the current year. Effective with the adoption of fresh start accounting as of September 30, 2014, Centrus immediately recognizes actuarial gains and losses in the statement of operations in the period in which they arise. The remeasurement of pension obligations as of June 30, 2015 under the non-qualified defined benefit pension plans and the Employees’ Retirement Plan of Centrus Energy Corp. resulted in a gain of $3.9 million included in selling, general and administrative expenses in the second quarter of 2015. The gain includes the effect of an increase in the discount rate used in the measurement of pension obligations from approximately 4.1% as of December 31, 2014 to approximately 4.5% as of June 30, 2015. Pension obligations under the Retirement Program Plan for Employees of United States Enrichment Corporation and the plans mentioned above were remeasured as of September 30, 2015, resulting in a loss of $21.6 million included in cost of sales and a loss of $3.2 million included in selling, general and administrative expenses in the third quarter of 2015. The discount rate used in the measurement of pension obligations as of September 30, 2015 was approximately 4.4% . The losses also include the effect of actual investment experience for pension plan assets relative to the expected return assumption of 6.75% per year. Other Plan Update The opportunity to participate in the Executive Deferred Compensation Plan was reactivated in June 2015 allowing deferrals beginning in July 2015. Enrollment in the plan had been suspended since January 2013. Qualified employees may defer compensation on a tax-deferred basis subject to plan limitations. Any matching contributions under the Company’s 401(k) plan that are foregone due to annual compensation limitations of the Internal Revenue Code are eligible to be received from the Company under the Executive Deferred Compensation Plan, provided that the employee deferred the maximum allowable pre-tax contribution in the 401(k) plan .

Earnings Per Share [Abstract]
Net Income (Loss) Per Share	NET INCOME (LOSS) PER SHARE Basic net income (loss) per share is calculated by dividing net income (loss) by the weighted average number of shares of common stock outstanding during the period, excluding any unvested restricted stock. In calculating diluted net income per share, the numerator is increased by interest and dividends on potentially dilutive securities, net of tax, and the denominator is increased by the weighted average number of shares resulting from potentially dilutive securities, assuming full conversion. No dilutive effect is recognized in a period in which a net loss has occurred. Net income (loss) per share information reported for the three and nine months ended September 30, 2015 is not comparative to the corresponding periods in 2014 as a result of the emergence from Chapter 11 bankruptcy and the application of fresh start accounting. On the Effective Date, all debt and stock of the Predecessor Company were cancelled and new debt and stock for the Successor Company were issued.

Commitments and Contingencies

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	COMMITMENTS AND CONTINGENCIES Lease Commitment Update In October 2015, Centrus signed a lease amendment that will reduce its office space at its corporate headquarters in Bethesda, Maryland. Under the amended lease, half of the lease payments for the Company’s current office space are abated until the Company moves into its new space in the first quarter of 2016, at which time the remaining lease commitment on the current space is fully abated. All of the lease payments on the new space are abated for the first fourteen months after occupation. The amended lease runs through October 2027 with an option to extend for five years. Future minimum lease payments through October 2027 under the amended lease follow (in millions): 2016 $ 0.2 2017 0.5 2018 0.8 2019 0.9 2020 0.9 Thereafter 6.6 $ 9.9 American Centrifuge Project Funding The economics for commercial deployment of the American Centrifuge technology are severely challenged by the current supply/demand imbalance in the market for LEU and related downward pressure on market prices for SWU that are now at their lowest levels in more than a decade. Under current market conditions, Centrus does not believe that its previous plans for commercialization of the American Centrifuge project are economically feasible. Although the economics of the American Centrifuge project are severely challenged under current nuclear fuel market conditions, market conditions are expected to improve in the long term and Centrus continues to take steps to maintain its options to deploy the American Centrifuge technology as a long-term, direct source of domestic enrichment production. From May 2014 through September 2015, Centrus performed continued research, development and demonstration of the American Centrifuge technology under the ACTDO Agreement. As Centrus reported on September 11, 2015, ORNL informed Centrus that DOE had decided to reduce funding for the American Centrifuge program and therefore ORNL intended to contract with the Company at a reduced level for the period from October 1, 2015 to September 30, 2016, with the possibility for additional extensions. The reduced scope excludes continued cascade operations at the Company’s Piketon, Ohio facility. Funding would be reduced by approximately 60% to $35 million per year, and the scope of activities would be limited to development and testing activities in Oak Ridge, Tennessee. The new contract is anticipated to be a firm fixed-price contract that would provide for payments on a monthly basis of approximately $2.9 million per month effective October 2015, down from approximately $6.9 million per month through September 2015. Centrus has no assurance that a final contract will be executed or that the amount and scope of the contract will be at the $2.9 million per month level. Centrus has been in discussions with DOE concerning obtaining additional funding to permit operations at Piketon to continue but has no assurance that additional funding will be provided. Centrus notified its American Centrifuge employees in September 2015 of possible layoffs beginning in November 2015 as a result of DOE’s decision to reduce funding under the contract with ORNL. Based on the level of funding reduction, Centrus incurred a special charge of $8.7 million in the third quarter of 2015 for estimated termination benefits consisting primarily of payments under its severance plan. The Company initiated a voluntary workforce reduction opportunity in October 2015 that is subject to management acceptance of volunteers. The voluntary selection process will be followed by an involuntary workforce reduction if funding for Piketon operations is not restored. The Company expects to make payments for these workforce reductions over the next 18 months. While Centrus is moving forward with actions to reduce costs and demobilize Piketon operations, the Company is doing so in a manner that preserves its ability to restore operations should funding be provided. Unless funding for Piketon operations is restored, Centrus may begin to take actions in the first quarter of 2016, including beginning to dismantle installed equipment and machines, that would increase the cost, time and difficulty of restoring operations at the Piketon facility. Should funding not be restored for operations at the Piketon, Ohio, facility, Centrus would incur costs associated with the reduction in scope. These costs could commence in the fourth quarter of 2015 as the Piketon workforce shifted to demobilization efforts and could extend into 2016. Demobilization costs are included in advanced technology costs. Refer to Note 3, Advanced Technology Costs and Other Income , regarding demobilization costs and maintenance costs related to prior reductions in scope. In addition to severance and demobilization costs, Centrus ultimately will have costs associated with the decontamination and decommissioning (“D&D”) of the Piketon facility in accordance with the requirements of the U.S. Nuclear Regulatory Commission (“NRC”) and DOE. Estimates for such costs have been included in the liability for D&D of the Piketon facility. The balance of this liability, included in other long-term liabilities, was $22.6 million as of September 30, 2015 and December 31, 2014 based on cost projections. DOE has title to certain American Centrifuge equipment. In the event Centrus returns the Piketon facility to DOE pursuant to its lease, DOE retains title to and responsibility for disposition of this equipment, and Centrus would seek reimbursement for any D&D costs the Company incurred related to this equipment. Centrus is required to provide financial assurance to the NRC and DOE for D&D and lease turnover costs under a regulatory-prescribed methodology that includes potential contingent costs and reserves. As of September 30, 2015 and December 31, 2014, Centrus has provided financial assurance to the NRC and DOE in the form of surety bonds totaling $29.4 million , which are fully cash collateralized by Centrus. Centrus expects to receive cash as surety bonds are cancelled following the Company’s performance of D&D. Milestones under the 2002 DOE-USEC Agreement The Company and DOE are parties to an agreement dated June 17, 2002, as amended (the “2002 DOE-USEC Agreement”), pursuant to which the Company and DOE made long-term commitments directed at resolving issues related to the stability and security of the domestic uranium enrichment industry. Pursuant to the Plan of Reorganization and with the consent of DOE, Centrus assumed the 2002 DOE-USEC Agreement subject to the parties reserving all rights under the agreement. The agreement provides that Centrus will develop, demonstrate and deploy advanced enrichment technology in accordance with milestones and provides for remedies in the event of a failure to meet a milestone under certain circumstances. The 2002 DOE-USEC Agreement provides DOE with specific remedies if Centrus fails to meet a milestone that would materially impact Centrus’ ability to begin commercial operations of the American Centrifuge Plant on schedule and such delay was within Centrus’ control or was due to Centrus’ fault or negligence. These remedies could include terminating the 2002 DOE-USEC Agreement, revoking Centrus’ access to DOE’s U.S. centrifuge technology that Centrus requires for the success of the American Centrifuge project and requiring Centrus to transfer certain of its rights in the American Centrifuge technology and facilities to DOE, and to reimburse DOE for certain costs associated with the American Centrifuge project. Any of these remedies under the 2002 DOE-USEC Agreement could have a material adverse impact on Centrus’ business. The 2002 DOE-USEC Agreement provides that if a delaying event beyond the control and without the fault or negligence of Centrus occurs that would affect Centrus’ ability to meet an American Centrifuge project milestone, DOE and Centrus will jointly meet to discuss in good faith possible adjustments to the milestones as appropriate to accommodate the delaying event. Centrus has notified DOE that it has not met the June 2014 milestone “Commitment to proceed with commercial operation” within the time period currently provided due to events beyond its control and without the fault or negligence of the Company. The assumption of the 2002 DOE-USEC Agreement provided for under the Plan of Reorganization did not impact the ability of either party to assert all rights, remedies and defenses under the agreement and all such rights, remedies and defenses are specifically preserved and all time limits tolled expressly including all rights, remedies and defenses and time limits relating to any missed milestones. DOE and Centrus have agreed that all rights, remedies and defenses of the parties with respect to any missed milestones since March 5, 2014, including the June 2014 and November 2014 milestones, and all other matters under the 2002 DOE-USEC Agreement continue to be preserved, and that the time limits for each party to respond to any missed milestones continue to be tolled. Potential ERISA Section 4062(e) Liability The Company has been in discussion with the PBGC and its financial advisor regarding the status of the qualified pension plans, including with respect to potential liability under ERISA Section 4062(e). On September 30, 2011, Enrichment Corp. completed the de-lease to DOE of the Portsmouth GDP and transition of employees performing government services work to DOE’s decontamination and decommissioning contractor. Enrichment Corp. notified the PBGC of this occurrence at that time. Further, at the end of May 2013, Enrichment Corp. ceased enrichment at the Paducah GDP and on October 21, 2014, completed the de-lease and return of the facility to DOE. In connection with the de-lease and return of the Paducah GDP to DOE, most of the remaining employees at the Paducah GDP were terminated. After receiving the Company’s notification of the transition of employees at the Portsmouth GDP in 2011, the PBGC staff at that time informally advised Enrichment Corp. of its preliminary view that the Portsmouth GDP transition was a cessation of operations that triggered liability under ERISA Section 4062(e) and that its preliminary estimate was that the ERISA Section 4062(e) liability (computed by taking into account the plan’s underfunding on a “termination basis,” which amount differs from that computed for GAAP purposes) for the Portsmouth GDP transition was approximately $130 million . At that time, Enrichment Corp. informed the PBGC that it did not agree with the PBGC staff’s view that ERISA Section 4062(e) liability was triggered in 2011, and also disputed the amount of the preliminary PBGC calculation of the potential ERISA Section 4062(e) liability. At the end of May 2013, the PBGC staff also informally advised Enrichment Corp. that the Paducah de-lease would be a cessation of operations under section 4062(e) when more than 20% of the Enrichment Corp.’s employees who are participants in a PBGC-covered pension plan were separated. The 20% reduction to the active plan participant threshold was reached at Paducah in April 2014. Subsequently, on December 16, 2014, the President signed into law the Consolidated and Further Continuing Appropriations Act, 2015 (the “CFCAA”), which made major changes to ERISA section 4062(e). The CFCAA changes the criteria for triggering liability under section 4062(e); provides certain exemptions from the applicability of section 4062(e) to certain events; permits companies to satisfy the liability by making payments into the pension over seven years, but ceases once the pension reaches a 90% funding level as calculated under the method provided in the CFCAA; subject to an exception not applicable here, prohibits the PBGC from taking any enforcement, administrative or other action under section 4062(e) that is inconsistent with the amendments made by the CFCAA based on events that occurred before the date of enactment (December 16, 2014); and permits companies to elect to satisfy any liability under section 4062(e) as provided in the CFCAA for an event that had occurred prior to date of enactment as if such cessation had occurred on such date of enactment. While the PBGC has not issued any guidance or rules regarding the implementation of the changes to section 4062(e), we believe that in the event the PBGC were to determine that a cessation of operations had occurred under section 4062(e) as a result of the Portsmouth GDP transition or the Paducah GDP transition (events that occurred before enactment of the CFCAA), the Company could elect to satisfy any section 4062(e) liability under the provisions of the CFCAA. As of January 1, 2014, (the first plan year for which payments would otherwise be required) the Enrichment Corp. pension plan was over 90% funded under the method used in the CFCAA. Consequently the Company believes that any such liability would be fully satisfied under the method provided in the CFCAA. The PBGC, however, has other authorities under ERISA that it may consider to address the Portsmouth and Paducah GDP transitions or otherwise in connection with the Company’s qualified defined benefit pension plans. These authorities include, but are not limited to, initiating involuntary termination of underfunded plans and seeking liens or additional funding. The Company would seek to defend against the assertion by the PBGC of any such authorities based on the facts and circumstances at the time. The involuntary termination by the PBGC of any of the qualified pension plans of Centrus or Enrichment Corp. would result in the termination of the limited, conditional guaranty by Enrichment Corp. of the PIK Toggle Notes (other than with respect to the unconditional interest claim). The Company has been engaged in discussions with the PBGC since the Portsmouth GDP transition. In 2014, prior to enactment of the CFCAA, the PBGC informed the Company that the PBGC had retained an outside financial advisor to advise the PBGC on the Company’s business and the need for and advisability of any actions that may be taken by the PBGC. The Company has continued discussions with PBGC and its financial advisor and has engaged a financial advisor on this matter. The PBGC has indicated it would like to discuss the potential for the Company to make contributions to the pension in advance of statutory funding requirements as amended by the Highway and Transportation Funding Act of 2014. The Company believes it is in the best interest of all stakeholders, including the PBGC, the covered plan participants and the Company, to continue funding of the qualified pension plans in the ordinary course and expects to do so, but there is no assurance that the PBGC will agree with that approach. Legal Matters On December 31, 2014, our subsidiary, Enrichment Corp., submitted a demand for binding arbitration to Entergy Services, Inc. and Entergy Nuclear Fuels Company (together with Entergy Services, Inc., “Entergy”) to resolve a dispute regarding their alleged repudiation of two sales contracts (the “Contracts”) with Enrichment Corp. On July 29, 2015, Enrichment Corp. and Entergy entered into a mutually acceptable Confidential Settlement Agreement (the “Settlement Agreement”) that resolved the arbitration through modifications to the Contracts. No monetary awards or payments will be made with respect to the Settlement Agreement. The Settlement Agreement represents a full and final resolution of the dispute related to the Contracts. A settlement was anticipated during the establishment of the non-cash intangible assets recorded through the application of fresh-start accounting on September 30, 2014. The Company concluded that the modifications made to the contracts with Entergy do not indicate that the related backlog intangible assets are no longer recoverable, and did not result in an impact to the balance of backlog intangible assets as of September 30, 2015. Centrus is subject to various legal proceedings and claims, either asserted or unasserted, which arise in the ordinary course of business. While the outcome of these claims cannot be predicted with certainty, Centrus does not believe that the outcome of any of these legal matters will have a material adverse effect on its results of operations or financial condition.
