El Cajon hydroelectric project
On August 31, 2007, the CFE paid our subsidiary CIISA U.S.$308 million, the second payment for the El Cajon hydroelectric project contract. We used the proceeds of the second payment and a U.S.$175 million reserve established with the proceeds of the first El Cajon payment to prepay in full the U.S.$230 million 144A bond due May 2008 and to prepay an additional U.S.$75 million in debt related to the El Cajon hydroelectric project.
We completed the construction phase of the El Cajon hydroelectric project and the CFE brought both turbogenerating units into commercial operation in August 2007. The units final acceptance requires performance tests, delivery of the project documents and finalization, closing and final payment of the contract, which are pending. Following the second payment of U.S.$308 million, the total payment we have received on the El Cajon contract to date is U.S.$833 million. We have recorded aggregate revenues of U.S.$873 million relating to the El Cajon hydroelectric project under the percentage-of-completion method of accounting. We are currently in discussions with the CFE regarding the final settlement of the El Cajon contract and the payment of outstanding amounts.
