Each owner is responsible for financing its share of each project and participates in decisions concerning operations and capital expenditures.SDG&E's share of operating expenses is included in Sempra Energy's and SDG&E's Consolidated Statements of Operations. SONGS DecommissioningObjectives, work scope, and procedures for the dismantling and decontamination of SONGS' three units must meet the requirements of the Nuclear Regulatory Commission (NRC), the Environmental Protection Agency (EPA), the U.S. Department of the Navy (the land owner), the CPUC and other regulatory bodies.SDG&E's asset retirement obligation related to decommissioning costs for the SONGS units was $492 million at December 31, 2010. That amount includes the cost to decommission Units 2 and 3, and the remaining cost to complete the decommissioning of Unit 1, which is substantially complete. Southern California Edison (Edison), the operator of SONGS, updates decommissioning cost studies every three years. Rate recovery of decommissioning costs is allowed until the time that the costs are fully recovered and is subject to adjustment every three years based on the costs allowed by regulators. Collections are authorized to continue until 2022. The most recent cost study was approved by the CPUC in July 2010. SDG&E's share of decommissioning costs under the approved study is approximately $768 million.Unit 1 was permanently shut down in 1992, and physical decommissioning began in January 2000. Most structures, foundations and large components have been dismantled, removed and disposed of. Spent nuclear fuel has been removed from the Unit 1 Spent Fuel Pool and stored on-site in an independent spent fuel storage installation (ISFSI) licensed by the NRC. The decommissioning of Unit 1 remaining structures (subsurface and intake/discharge) will take place when Units 2 and 3 are decommissioned. The ISFSI will be decommissioned after a permanent storage facility becomes available and the U.S. Department of Energy (DOE) removes the spent fuel from the site. The Unit 1 reactor vessel is expected to remain on site until Units 2 and 3 are decommissioned. The amounts collected in rates for SONGS' decommissioning are invested in externally managed trust funds. Amounts held by the trusts are invested in accordance with CPUC regulations. These trusts are shown on the Sempra Energy and SDG&E Consolidated Balance Sheets at fair value with the offsetting credits recorded in Regulatory Liabilities Arising from Removal Obligations.The following table shows the fair values and gross unrealized gains and losses for the securities held in the trust funds.<div><table style="border-collapse:collapse;margin-top:20px;"><tr style="height: 19px"><td colspan="10" style="width: 648px;
