SUBSEQUENT EVENTIn January 2011, Sempra Pipelines & Storage agreed to acquire from AEI its interests in Chilquinta Energía S.A. (Chilquinta Energía) in Chile and Luz del Sur S.A. (Luz del Sur) in Peru. At March 31, 2011, Sempra Pipelines & Storage and AEI each owned 50 percent of Chilquinta Energía and approximately 38 percent of Luz del Sur. We completed the transaction on April 6, 2011, and Sempra Pipelines & Storage now owns 100 percent of Chilquinta Energía and approximately 76 percent of Luz del Sur, with the remaining shares of Luz del Sur held by institutional investors and the general public. The purchase price was $875 million (plus working capital adjustments of $13 million), which resulted from valuing the assets in Chile at $490 million and the assets in Peru at $385 million. As part of our acquisition of AEI's interest in Luz del Sur, we are required to launch a tender offer to the minority shareholders of Luz del Sur to purchase their shares at a price as determined by an independent appraiser.  As part of the transaction, Sempra Pipelines & Storage also acquired AEI's interests in two energy-services companies, Tecnored S.A. and Tecsur S.A. We provide additional information about Sempra Pipelines & Storage's investments in Chilquinta Energía and Luz Del Sur in Note 4 of the Notes to Consolidated Financial Statements in the Annual Report.Due to the limited time since the date of the acquisition, the initial accounting for this business combination is incomplete as of the date of this filing, including updated appraisal information for the acquisition.
