Contract Services and Advanced Technology License and Decommissioning Costs | CONTRACT SERVICES AND ADVANCED TECHNOLOGY LICENSE AND DECOMMISSIONING COSTS The contract services segment includes Revenue and Cost of Sales for engineering and testing work Centrus performs on the American Centrifuge technology under government contract with UT-Battelle. Centrus entered into a new contract with UT-Battelle on September 19, 2016, valued at approximately $25 million for the period from October 1, 2016, through September 30, 2017 (the “2017 ORNL Contract”). The 2017 ORNL Contract provides for payments for monthly reports of approximately $2.0 million per month and additional aggregate payments of $1.0 million based on completion of certain milestones. The 2017 ORNL Contract is currently being funded incrementally. Funding for the program is provided to UT-Battelle by the federal government which is currently operating under a continuing resolution. The Company’s contract with UT-Battelle that ended September 30, 2016 (the “2016 ORNL Contract”), provided for payments for monthly reports of approximately $2.7 million per month. The amount of funding under the 2016 ORNL Contract decreased from approximately $6.9 million per month received under contract for the government fiscal year that ended September 30, 2015 (the “2015 ORNL Contract”). Although the 2015 ORNL Contract expired September 30, 2015, Centrus continued to perform work at the expected reduced scope as the parties worked toward a successor agreement. The 2016 ORNL Contract, which was signed in March 2016, provided for payment for reports related to work performed since October 1, 2015. Revenue in 2016 includes $8.1 million for March 2016 reports on work performed in the three months ended December 31, 2015, and $30.4 million for reports on work performed in the year ended December 31, 2016. Expenses for contract work performed in the year ended December 31, 2016, are included in Cost of Sales. Expenses for work performed in the three months ended December 31, 2015, before entering into the 2016 ORNL Contract, were included in Advanced Technology License and Decommissioning Costs in 2015. American Centrifuge expenses that are outside of the Company’s contracts with UT-Battelle are included in Advanced Technology License and Decommissioning Costs, including ongoing costs to maintain the demobilized Piketon facility and our NRC licenses at that location. In the second quarter of 2016, the Company commenced with the D&D of the Piketon facility in accordance with the requirements of the NRC and DOE. Charges to Advanced Technology License and Decommissioning Costs included approximately $19 million in 2016 and approximately $7 million in 2015 to increase the accrued D&D liability based on updated cost estimates that reflect changes in the approach and anticipated timeframe over which the work will be conducted. As of December 31, 2016, the Company has accrued $38.6 million on the balance sheet as Decontamination and Decommissioning Obligations for the estimated fair value of the remaining costs to complete the D&D work. Refer to Note 16, Commitments and Contingencies, for additional details.
