Asset Additions and Dispositions | Asset Additions and Dispositions New Generation Nuclear. On August 18, 2011, the TVA Board approved the completion of Bellefonte Unit 1. The project is scheduled to be completed by 2020 for anticipated additional costs of $4.9 billion exclusive of AFUDC and the cost of the initial fuel load. Further action by the NRC and reviews by TVA are required before construction activities can resume. In addition, the TVA Board directed that construction activities not be resumed at Bellefonte Unit 1 until the initial loading of fuel at Watts Bar Unit 2 has been accomplished. See Note 20 — Legal Proceedings — Case Regarding Bellefonte Nuclear Plant Units 1 and 2. Combined Cycle. TVA is in the process of completing the John Sevier Combined Cycle Facility in northeastern Tennessee. TVA expects to complete this combined cycle facility by mid-CY 2012. The completed facility is expected to add approximately 880 MW of summer net capability to the TVA system at a cost of approximately $820 million. On August 31, 2011, TVA purchased Magnolia for $436 million. As a result of the purchase price allocation performed in accordance with ASC 805 — Business Combinations, $424 million was allocated to Completed plant and $12 million was allocated to Inventories, net. Approximately $11 million of the purchase price will be held by TVA to secure the seller's indemnity obligations under the acquisition agreement. This amount is recorded in Restricted cash and investments and Other long-term liabilities and is to be paid to the seller on the 547th day after closing assuming the related obligations have been met. TVA expects the full amount to be paid at that time. TVA expensed transaction costs related to the acquisition as incurred. Supplemental pro forma data has not been supplied as the acquisition was not significant. Buildings On January 3, 2011, TVA purchased the portion of TVA’s Chattanooga Office Complex in Chattanooga, Tennessee, leased from Chattanooga Valley Associates (with the exception of Monteagle Place, which includes approximately 131,979 square feet) upon the expiration of the existing lease term for that portion on January 1, 2011. The purchase price was $22 million. On May 18, 2009, TVA finalized an agreement to purchase the Monteagle Place portion of the Chattanooga Office Complex upon the expiration of the existing lease term on October 1, 2012. The purchase price for Monteagle Place is $8 million. TVA paid $2 million on October 1, 2009, $2 million on October 1, 2010, $2 million on October 1, 2011, and will pay an additional $2 million on October 1, 2012, to satisfy its purchase price commitment. As a result of these transactions, the capital lease liability and the property, plant, and equipment account for capital leases were adjusted in accordance with the applicable accounting guidance related to leased assets purchased by a lessee during the term of a lease.
