Commitments and Contingencies	12. COMMITMENTS AND CONTINGENCIES Power Contract On May 15, 2012, the power purchase agreement with TVA was amended to extend its term and TVA and USEC entered into a supplemental confirmation agreement pursuant to the amended power purchase agreement for USEC to purchase the power needed to operate the Paducah GDP during the one-year term of the depleted uranium enrichment agreement with Energy Northwest. Under this supplemental agreement, USEC has a take or pay obligation to purchase electricity during June - September 2012 at monthly amounts increasing from approximately 750 to 1,250 megawatts and then at 1,500 megawatts for the remaining months of the contract, less a 25% reduction in May 2013 to provide a transition in power delivery. As of June 30, 2012, USEC is obligated to make minimum payments under the supplemental agreement and the amended power purchase agreement of approximately $0.5 billion through May 2013. USEC's costs are subject to monthly fuel cost adjustments to reflect changes in TVA's fuel costs, purchased power costs, and related costs. However, these fuel cost adjustments are passed through to Energy Northwest under the depleted uranium enrichment agreement. USEC has the right to terminate its power purchase obligations under the supplemental agreement if Energy Northwest terminates the depleted uranium enrichment agreement, or fails to deliver depleted uranium or to meet its payment obligations, and USEC ceases enrichment operations at Paducah as a result. In such a case, USEC will agree with TVA on a schedule to reduce to zero over a period of thirty days all power purchases in a manner that ensures safe and reliable operation of Paducah. American Centrifuge Plant Project Funding USEC needs significant additional financing in order to complete the American Centrifuge Plant ("ACP"). USEC believes a loan guarantee under the DOE Loan Guarantee Program, which was established by the Energy Policy Act of 2005, is essential to obtaining the funding needed to complete the ACP. In July 2008, USEC applied under the DOE Loan Guarantee Program for $2 billion in U.S. government guaranteed debt financing for the ACP. As discussed in Note 4, instead of moving forward with a conditional commitment for a loan guarantee, in the fall of 2011, DOE proposed a two-year RD&D program for the project. DOE indicated that USEC's application for a DOE loan guarantee would remain pending during the RD&D program but has given USEC no assurance that a successful RD&D program will result in a loan guarantee. Additional capital beyond the $2 billion of DOE loan guarantee funding that USEC has applied for and USEC's internally generated cash flow will be required to complete the project. USEC has had discussions with Japanese export credit agencies regarding financing up to $1 billion of the cost of completing the ACP. Additional capital will also be needed and the amount of additional capital is dependent on a number of factors, including the amount of any revised cost estimate and schedule for the project, the amount of contingency or other capital DOE may require as part of a loan guarantee, and the amount of the DOE credit subsidy cost that would be required to be paid in connection with a loan guarantee. USEC has no assurances that it will be successful in obtaining this financing and that the delays it has experienced will not adversely affect these efforts. If conditions change and deployment of the ACP becomes no longer probable or becomes delayed significantly from USEC's current expectations, USEC could expense up to the full amount of previously capitalized costs related to the ACP of up to $1.1 billion. Events that could impact USEC's views as to the probability of deployment or USEC's projections include progress in meeting the technical milestones of the RD&D program, the status of continued DOE funding for the RD&D program, changes in USEC's anticipated ownership of or role in the project, changes in the cost estimate and schedule for the project, and prospects for obtaining a loan guarantee and other financing needed to deploy the project. The objectives of the RD&D program are (1) to demonstrate the American Centrifuge technology through the construction and operation of a cascade of 120 commercial centrifuge machines and (2) to sustain the domestic U.S. centrifuge technical and industrial base for national security purposes and potential commercialization of the American Centrifuge project. This includes activities to reduce the risks and improve the future prospects of deployment of the American Centrifuge technology. USEC intends to meet these objectives through the construction and operation of one complete demonstration cascade of 120 commercial centrifuge machines and supporting infrastructure. This will enable us to demonstrate redundancy of the primary cascade support systems for commercial plant operation and to complete integrated testing against operational requirements. USEC began funding the RD&D program in January 2012 and has been building machines and parts for the demonstration cascade. On June 12, 2012, USEC and DOE entered into a cooperative agreement to provide funding for the RD&D program. The cooperative agreement provides for 80% DOE and 20% USEC cost sharing for work performed during the period June 1, 2012 through December 31, 2013 with a total estimated cost of $350 million. DOE's total contribution would be up to $280 million and USEC's contribution would be up to $70 million. USEC's 20% contribution will include investments made by USEC commencing June 1, 2012. DOE's contribution will be incrementally funded and is limited to $87.7 million until DOE provides authorization for additional funding. DOE funding through July 31, 2012 was $26.4 million. On July 31, 2012, DOE authorized an additional $61.3 million of funding (for a total of $87.7 million). The remaining funding of $192.3 million from DOE has not yet been authorized and is subject to Congressional appropriations, Congressional transfer or reprogramming authority to permit the use by DOE of funds previously appropriated for other programs, or other sources available to DOE and therefore it is possible that this additional funding may not be made available. DOE provided the initial $87.7 million of funding by accepting title to quantities of depleted uranium that will enable USEC to release encumbered funds for approximately 80% of the allowable costs of the RD&D program up to $87.7 million. As described in Note 5, USEC receives the cash when the surety bonds and related cash deposits providing the financial assurance for disposition of this depleted uranium are reduced. Under the cooperative agreement, USEC and USEC's newly created subsidiary American Centrifuge Demonstration, LLC ("ACD") will carry out the RD&D program. ACD is putting in place a program management and enhanced program execution structure as required by the cooperative agreement. On July 23, 2012, USEC entered into a limited liability company agreement for ACD which, among other things, establishes a board of managers in accordance with the enhanced program execution structure. The seven-person board is comprised of two independent managers, two managers appointed by USEC, and one manager appointed by each of Babcock & Wilcox Technical Services Group, Inc., Toshiba America Nuclear Energy Corporation and Exelon Generation Company, LLC. The cooperative agreement also includes five technical milestones for the RD&D program. On June 27, 2012, USEC achieved the first technical milestone related to the finalization of a test program plan for the remaining technical milestones and for full system reliability and plant availability. Submittal of a more detailed cost and schedule for the RD&D program, including the dates for the technical milestones, was also a condition to DOE providing funding beyond the initial $26.4 million of funding. On July 24, 2012, USEC submitted the required information. DOE has the right to terminate the cooperative agreement if any of these technical milestones are not met on or before the agreed date for such milestones. DOE also has the right to terminate the cooperative agreement if USEC materially fails to comply with the other terms and conditions of the cooperative agreement. Failure to meet the technical milestones under the cooperative agreement could provide a basis for DOE to exercise its remedies under the 2002 DOE-USEC Agreement (as defined below). On June 12, 2012, USEC through its subsidiary also entered into a contract with DOE to transfer to DOE title to the centrifuge machines and equipment produced or acquired under the RD&D program. The transferred property includes some existing machines and equipment and, at DOE's option, the machines and equipment produced or acquired under the cooperative agreement. As compensation for the sale of the transferred property, (1) DOE will make the transferred property available for no additional fee as leased personal property under the lease agreement between DOE and USEC for the facilities at Piketon, Ohio for the American Centrifuge Plant, and (2) at financial closing on the financing for the construction of the American Centrifuge Plant, title to the transferred property will transfer to the lessee under and in accordance with the terms of the lease agreement. If USEC abandons the centrifuge technology and returns the premises leased under the DOE lease agreement, DOE will keep the transferred property and would be responsible for its disposal. Milestones under the 2002 DOE-USEC Agreement On June 12, 2012, USEC and DOE entered into an amendment to the agreement dated June 17, 2002 between DOE and USEC (such agreement, as amended, the "2002 DOE-USEC Agreement"). Under the 2002 DOE-USEC Agreement, USEC and DOE made long-term commitments directed at resolving issues related to the stability and security of the domestic uranium enrichment industry. The agreement provides that USEC will develop, demonstrate and deploy the American Centrifuge technology in accordance with milestones and provides for remedies in the event of a failure to meet a milestone under certain circumstances. The June 2012 amendment adds two new milestones related to the RD&D program and revises the remaining four milestones under the 2002 agreement relating to the financing and operation of the American Centrifuge Plant to be aligned with the RD&D program. USEC also granted to DOE an irrevocable, non-exclusive right to use or permit third parties on behalf of DOE to use all American Centrifuge technology intellectual property ("Centrifuge IP") royalty free for U.S. government purposes (which includes completion of the cascade demonstration test program and national defense purposes, including providing nuclear material to operate commercial nuclear power reactors for tritium production). USEC also granted an irrevocable, non-exclusive license to DOE to use such Centrifuge IP developed at USEC's expense for commercial purposes (including a right to sublicense), which may be exercised only if USEC misses any of the milestones under the 2002 DOE-USEC Agreement or if USEC (or an affiliate or entity acting through USEC) is no longer willing or able to proceed with, or has determined to abandon or has constructively abandoned, the commercial deployment of the centrifuge technology. Such commercial purposes licenses are subject to payment of a reasonable royalty to USEC, which shall not exceed $665 million. The 2002 DOE-USEC Agreement provides DOE with specific remedies if USEC fails to meet a milestone that would materially impact USEC's ability to begin commercial operations of the American Centrifuge Plant on schedule and such delay was within USEC's control or was due to USEC's fault or negligence. These remedies could include terminating the 2002 DOE-USEC Agreement, revoking USEC's access to DOE's U.S. centrifuge technology that USEC requires for the success of the American Centrifuge project and requiring USEC 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. DOE could also recommend that USEC be removed as the sole U.S. Executive Agent under the nonproliferation program between the United States and the Russian Federation known as "Megatons to Megawatts," which could affect USEC's access to Russian LEU under the Megatons to Megawatts program in 2013. Any of these remedies under the 2002 DOE-USEC Agreement could have a material adverse impact on USEC's business. The 2002 DOE-USEC Agreement provides that if a delaying event beyond the control and without the fault or negligence of USEC occurs which would affect USEC's ability to meet an ACP milestone, DOE and USEC will jointly meet to discuss in good faith possible adjustments to the milestones as appropriate to accommodate the delaying event. USEC's right to continue operating the Paducah GDP under its lease with DOE is not subject to meeting the ACP milestones. In addition, the new 10-year commercial supply agreement entered into on March 23, 2011 with TENEX is not subject to any of the remedies related to the ACP under the 2002 DOE-USEC Agreement. NYSE Listing Notice On May 8, 2012, USEC received notice from the New York Stock Exchange ("NYSE") that the average closing price of its common stock was below the NYSE's continued listing criteria relating to minimum share price. Rule 802.01C of the NYSE's Listed Company Manual requires that a company's common stock trade at a minimum average closing price of $1.00 over a consecutive 30 trading-day period. In accordance with the NYSE's rules, on May 14, 2012, USEC provided written notice to the NYSE of its intent to cure this deficiency. USEC is evaluating its options to cure the price deficiency, including a reverse stock split, which would require shareholder approval at or prior to USEC's next annual meeting of shareholders. USEC has six months from receipt of the notice to regain compliance with the NYSE's price criteria (or by no later than USEC's next annual meeting of shareholders if shareholder approval is required). Subject to the NYSE's rules, during the cure period, USEC's common stock will continue to be listed and trade on the NYSE, subject to its continued compliance with the NYSE's other applicable listing rules. USEC is currently in compliance with all other NYSE listing rules. USEC can regain compliance at any time during the six-month cure period if on the last trading day of a calendar month during the cure period, USEC has a closing share price of at least $1.00 and an average closing share price of at least $1.00 over the 30 trading-day period ending on the last trading-day of that month or on the last day of the cure period. If USEC effectuates a reverse stock split vote by no later than the next annual meeting of shareholders to cure the condition, the condition will be deemed cured if the price promptly exceeds $1.00 per share, and the price remains above the level for at least the following 30 trading days. Legal Matters USEC 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, USEC does not believe that the outcome of any of these legal matters will have a material adverse effect on its results of operations, cash flows or financial condition. On June 27, 2011, a complaint was filed in the United States District Court for the Southern District of Ohio, Eastern Division, against USEC by a former Portsmouth GDP employee claiming that USEC owes severance benefits to him and other similarly situated employees that have transitioned or will transition to the DOE decontamination and decommissioning ("D&D") contractor. The plaintiff amended its complaint on August 31, 2011 and February 10, 2012, among other things, to limit the purported class of similarly situated employees to salaried employees at the Portsmouth site who transitioned to the D&D contractor and are allegedly eligible for or owed benefits. USEC believes it has meritorious defenses against the suit and has not accrued any amounts for this matter. An estimate of the possible loss or range of loss from the litigation is difficult to make because, among other things, (i) the plaintiff has failed to state the amount of damages sought, (ii) the plaintiff purports to represent a class of claimants the size and composition of which remains unknown and (iii) the certification of the class is uncertain. However, USEC estimates that the total severance liability for the approximately 400 salaried employees at the Portsmouth site that transitioned to the DOE D&D contractor would have been approximately $14 million if severance was required to be paid to all of these employees. In such an event, DOE would have owed a portion of this amount, estimated at approximately $9 million, assuming DOE was responsible for periods both during which it operated the facility and under which USEC was a direct contractor to DOE.

If USEC abandons the centrifuge technology and returns the premises leased under the DOE lease agreement, DOE will keep the transferred property and would be responsible for its disposal.

Milestones under the 2002 DOE-USEC Agreement

On June 12, 2012, USEC and DOE entered into an amendment to the agreement dated June 17, 2002 between DOE and USEC (such agreement, as amended, the "2002 DOE-USEC Agreement"). Under the 2002 DOE-USEC Agreement, USEC and DOE made long-term commitments directed at resolving issues related to the stability and security of the domestic uranium enrichment industry.

The agreement provides that USEC will develop, demonstrate and deploy the American Centrifuge technology in accordance with milestones and provides for remedies in the event of a failure to meet a milestone under certain circumstances. The June 2012 amendment adds two new milestones related to the RD&D program and revises the remaining four milestones under the 2002 agreement relating to the financing and operation of the American Centrifuge Plant to be aligned with the RD&D program.

USEC's right to continue operating the Paducah GDP under its lease with DOE is not subject to meeting the ACP milestones. In addition, the new 10-year commercial supply agreement entered into on March 23, 2011 with TENEX is not subject to any of the remedies related to the ACP under the 2002 DOE-USEC Agreement.

NYSE Listing Notice

On May 8, 2012, USEC received notice from the New York Stock Exchange ("NYSE") that the average closing price of its common stock was below the NYSE's continued listing criteria relating to minimum share price. Rule 802.01C of the NYSE's Listed Company Manual requires that a company's common stock trade at a minimum average closing price of $1.00 over a consecutive 30 trading-day period. In accordance with the NYSE's rules, on May 14, 2012, USEC provided written notice to the NYSE of its intent to cure this deficiency. USEC is evaluating its options to cure the price deficiency, including a reverse stock split, which would require shareholder approval at or prior to USEC's next annual meeting of shareholders. USEC has six months from receipt of the notice to regain compliance with the NYSE's price criteria (or by no later than USEC's next annual meeting of shareholders if shareholder approval is required). Subject to the NYSE's rules, during the cure period, USEC's common stock will continue to be listed and trade on the NYSE, subject to its continued compliance with the NYSE's other applicable listing rules. USEC is currently in compliance with all other NYSE listing rules.

USEC can regain compliance at any time during the six-month cure period if on the last trading day of a calendar month during the cure period, USEC has a closing share price of at least $1.00 and an average closing share price of at least $1.00 over the 30 trading-day period ending on the last trading-day of that month or on the last day of the cure period. If USEC effectuates a reverse stock split vote by no later than the next annual meeting of shareholders to cure the condition, the condition will be deemed cured if the price promptly exceeds $1.00 per share, and the price remains above the level for at least the following 30 trading days.

Legal Matters

USEC 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, USEC does not believe that the outcome of any of these legal matters will have a material adverse effect on its results of operations, cash flows or financial condition.

On June 27, 2011, a complaint was filed in the United States District Court for the Southern District of Ohio, Eastern Division, against USEC by a former Portsmouth GDP employee claiming that USEC owes severance benefits to him and other similarly situated employees that have transitioned or will transition to the DOE decontamination and decommissioning ("D&D") contractor. The plaintiff amended its complaint on August 31, 2011 and February 10, 2012, among other things, to limit the purported class of similarly situated employees to salaried employees at the Portsmouth site who transitioned to the D&D contractor and are allegedly eligible for or owed benefits. USEC believes it has meritorious defenses against the suit and has not accrued any amounts for this matter. An estimate of the possible loss or range of loss from the litigation is difficult to make because, among other things, (i) the plaintiff has failed to state the amount of damages sought, (ii) the plaintiff purports to represent a class of claimants the size and composition of which remains unknown and (iii) the certification of the class is uncertain. However, USEC estimates that the total severance liability for the approximately 400 salaried employees at the Portsmouth site that transitioned to the DOE D&D contractor would have been approximately $14 million if severance was required to be paid to all of these employees. In such an event, DOE would have owed a portion of this amount, estimated at approximately $9 million, assuming DOE was responsible for periods both during which it operated the facility and under which USEC was a direct contractor to DOE.
