COMMITMENTS AND CONTINGENCIES

Commitments under SWU Purchase Agreement

The Company signed an agreement with the Russian government entity Joint Stock Company "TENEX" ("TENEX") in 2011 for the 10-year supply of Russian LEU. Under the terms of the agreement, the supply of LEU to the Company began in 2013. Beginning in 2015, TENEX and Centrus may mutually agree to increase the purchases and sales of SWU by certain optional quantities of SWU. The LEU that Centrus obtains from TENEX under the agreement is subject to quotas and other restrictions applicable to commercial Russian LEU. Deliveries under the supply agreement are expected to continue through 2022. Centrus purchases the SWU component of the LEU and delivers natural uranium to TENEX for the LEU’s uranium component. The pricing terms for SWU under the contract are based on a mix of market-related price points and other factors.

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 viable. Although the economics of the American Centrifuge project are severely challenged under current nuclear fuel market conditions, market conditions are expected to improve and Centrus continues to take steps to maintain its options to commercially deploy the American Centrifuge technology as a long-term, direct source of domestic enrichment production to support the long-term viability of the Company's LEU business.

From June 2012 through April 2014, the Company performed work under the Cooperative Agreement, as amended, for the research, development and demonstration of the American Centrifuge technology. The Company achieved or exceeded all of the program technical milestones and performance indicators on or ahead of schedule and on or under budget, and the Cooperative Agreement expired by its terms on April 30, 2014.

In light of the strategic value of the American Centrifuge technology, DOE instructed UT-Battelle, the management and operating contractor for ORNL, to assist in developing a path forward for achieving a reliable and economic domestic uranium enrichment capability that promotes private sector deployment and supports national security purposes. This task includes, among other goals: (1) taking actions intended to promote the continued operability of the advanced enrichment centrifuge machines and related property, equipment and technology currently utilized in the American Centrifuge project; and (2) assessing technical options for meeting DOE’s national security needs and preserving the option of commercial deployment. Pursuant to those instructions, ORNL chose to subcontract with the Company. On May 1, 2014, the Company signed the ACTDO Agreement with UT-Battelle for continued research, development and demonstration of the American Centrifuge technology in furtherance of DOE’s national security objectives.

The ACTDO Agreement is a firm fixed-price contract that provides for continued cascade operations at the Company's Piketon, Ohio facility, testing at the K-1600 test facility in Oak Ridge, Tennessee, core American Centrifuge research and technology activities and the furnishing of related reports to ORNL. The scope of the overall work under the ACTDO Agreement is reduced from the scope of work that was being conducted by the Company under the prior Cooperative Agreement with DOE. The reduced scope of work does not include activities related to engineering, procurement and construction of the commercial plant; work related to the manufacturing of new centrifuge machines; or design, testing, and procurement of specialty uranium handling equipment necessary to support the uranium enrichment process. In order to align its continued activities with the funding provided under the ACTDO Agreement, the Company commenced a limited demobilization of those activities not included in the ACTDO Agreement scope of work and began to sell or otherwise dispose of certain assets no longer required to conduct current activities including the sale of assets through an auction process.

In July 2014 and again in January 2015, ORNL exercised its options to extend the period of performance for the ACTDO Agreement for additional six-month periods to September 30, 2015. The two extensions have increased the total price to approximately $117 million for the period from May 1, 2014 to September 30, 2015. A bipartisan consensus in Congress and the Administration recognized the importance of maintaining the American Centrifuge technology for national and energy security purposes and funding for ACTDO Agreement activities was included in the government fiscal year 2015 omnibus appropriation signed by President Obama in December 2014. Further, the Administration’s budget request for government fiscal year 2016 includes $100 million for domestic uranium enrichment to maintain the current centrifuge program while the Administration finalizes its assessment of how best to meet U.S. national security and non-proliferation goals. Appropriations for government fiscal year 2016 will require further action from both Congress and the President.

The ACTDO Agreement is incrementally funded and provides for payments on a monthly basis at a rate of approximately $6.7 million per month through September 30, 2014 and approximately $6.9 million per month thereafter.

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 which 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 June 2002 Agreement continued to be preserved, and that the time limits for each party to respond to any missed milestones continue to be tolled.

Decontamination and Decommissioning

Centrus leases facilities in Piketon, Ohio from DOE for the ACP. At the conclusion of the lease, Centrus is obligated to return these leased facilities to DOE in a condition that meets U.S. Nuclear Regulatory Commission ("NRC") requirements and in the same condition as the facilities were in when they were leased to Centrus (other than due to normal wear and tear). Centrus must remove all Company-owned capital improvements at the ACP, unless otherwise consented to by DOE, by the conclusion of the lease term. The liability for ACP D&D, included in other long-term liabilities, was $22.6 million as of December 31, 2014 and December 31, 2013 based on cost projections.

Centrus is required to provide financial assurance to the NRC and DOE for D&D costs under a regulatory-prescribed methodology that includes potential contingent costs and reserves. As of December 31, 2014 and December 31, 2013, Centrus has provided financial assurance to the NRC and DOE in the form of surety bonds totaling $29.4 million, which is fully cash collateralized by Centrus.

If construction of the ACP is resumed, the liability for ACP D&D and financial assurance requirements will increase commensurate with facility construction and operations.

Waste Disposition

The Company's prior enrichment operations generated hazardous, low-level radioactive and mixed wastes. The storage, treatment, and disposal of wastes are regulated by federal and state laws. Wastes from our prior operations at the Paducah GDP have been shipped to off-site treatment and disposal facilities. Liabilities accrued for the treatment and disposal of wastes generated by the Company's operations at the Paducah GDP, included in accounts payable and accrued liabilities, amounted to $1.0 million at December 31, 2014 and $1.8 million at December 31, 2013.

The Company ceased uranium enrichment at the Portsmouth GDP in 2001. During subsequent years, the Company maintained the Portsmouth site and performed services under contract with DOE. On September 30, 2011, the Company completed the transition of Portsmouth site facilities to DOE. As part of the transition, at the Company’s request, the NRC terminated the Company’s certificate of compliance for the Portsmouth site. In connection with the return of facilities, DOE agreed to accept ownership of all nuclear material at the site, some of which required processing for waste disposal. The Company agreed to pay DOE its cost of disposing of such wastes. The accrued disposal obligation, included in accounts payable and accrued liabilities, is $2.6 million at December 31, 2014 and $5.5 million at December 31, 2013.

The USEC Privatization Act and our lease with DOE provide that DOE remains responsible for the decontamination and decommissioning of the Paducah and Portsmouth sites.

Potential ERISA Section 4062(e) Liability

The Company has been in discussion with the PBGC and its advisors 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 D&D 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 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 cease 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 New 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 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

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.

Lease Commitments

Operating costs incurred under the operating leases with DOE for the Paducah, Piketon, and Oak Ridge facilities, and leases for office space and equipment amounted to $7.0 million in 2014 and $7.1 million in 2013. Future estimated minimum lease payments and expected lease administration payments follow (in millions):



2015	$	4.7
2016	3.6
2017	1.9
2018	1.9
2019	1.9
Thereafter	43.9
	$	57.9

On October 21, 2014, all of the leased portions of the Paducah GDP were de-leased and returned to DOE. Pursuant to a June 2014 agreement with DOE, the lease will terminate with respect to the Paducah GDP on August 1, 2015.

Centrus has a lease with DOE for centrifuge testing facilities in Oak Ridge through January 2016. Centrus leases facilities in Piketon for the American Centrifuge Plant from DOE. The current five-year lease term is through June 2019. Centrus has the option to extend the lease term for additional five-year terms ending in 2043. Thereafter, Centrus has the right to extend the American Centrifuge Plant lease for up to an additional 20 years, through 2063, if it agrees to demolish the existing buildings leased to Centrus after the lease term expires and subject to certain other conditions. Centrus may terminate the American Centrifuge Plant lease upon three years’ notice. DOE may terminate the lease for default, including if DOE is able to exercise its remedies with respect to the ACP under the 2002 DOE-USEC Agreement.

Centrus has office space and equipment leases for its corporate headquarters in Bethesda, Maryland through November 2016.

DOE Technology License

The Company has a non-exclusive license in DOE inventions that pertain to enriching uranium using gas centrifuge technology. The license agreement with DOE provides for annual royalty payments based on a varying percentage (1% up to 2%) of the Company’s annual revenues from sales of the SWU component of LEU produced by the Company at the American Centrifuge Plant and any other facility using DOE centrifuge technology. There is a minimum annual royalty payment of $100,000 and the maximum cumulative royalty over the life of the license is $100 million. The license may be terminated by DOE in the event DOE is able to exercise its remedies with respect to the ACP under the 2002 DOE-USEC Agreement.
