Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrants under any of the following provisions (see General Instruction A.2. below):

Citibank, N.A. (“Citibank”), as Administrative Agent under that certain Credit Agreement, dated as of October 10, 2007, as amended August 7, 2009, by and among Energy Future Competitive Holdings Company (“EFCH”), as guarantor, Texas Competitive Electric Holdings Company LLC (“TCEH”), as borrower, and the lenders party thereto from time to time (the “TCEH Senior Secured Credit Facilities”), has informed TCEH that Citibank received a letter from Aurelius Capital Management, LP (“Aurelius”), a lender under the TCEH Senior Secured Credit Facilities, alleging that TCEH is in default under the terms of the TCEH Senior Secured Credit Facilities. We believe that all of the allegations in Aurelius’ letter are without merit. Neither the letter from Aurelius nor the communication from Citibank regarding the letter causes the acceleration of any of Energy Future Holdings Corp.’s (“EFH”), TCEH’s or their respective affiliates’ debt, including the TCEH Senior Secured Credit Facilities.

The letter from Aurelius principally alleges that certain intercompany loans from TCEH to EFH, its indirect parent company, do not comply with the requirement in the TCEH Senior Secured Credit Facilities that these loans be made on an arm’s-length basis. Aurelius further alleges that this noncompliance has resulted in a failure to make certain mandatory prepayments under the TCEH Senior Secured Credit Facilities. TCEH disagrees with each of Aurelius’ allegations. We believe the loans comply with the arm’s-length requirement in the TCEH Senior Secured Credit Facilities and that no event of default has occurred. The loans reflect arm’s-length terms that are comparable to the terms that unrelated parties would have negotiated in the market. Information regarding these loans, including the interest rate and amounts outstanding thereunder, has been disclosed in numerous filings with the Securities and Exchange Commission by EFCH and discussed on numerous EFH quarterly investor calls.

Citibank has advised us that, as of February 24, 2011, Aurelius holds approximately $50 million aggregate principal amount of term loans as a lender of record, or approximately 0.2%, of the approximately $23.9 billion aggregate principal amount of debt outstanding under the TCEH Senior Secured Credit Facilities. Of the hundreds of lenders of record under the TCEH Senior Secured Credit Facilities, no other lender was listed in the letter as supporting Aurelius’ allegations and, as of the date of this Current Report on Form 8-K, no other lender has asserted that these loans constitute an event of default under the TCEH Senior Secured Credit Facilities. Generally, under the terms of the TCEH Senior Secured Credit Facilities, the Administrative Agent is only required to declare the debt under the TCEH Senior Secured Credit Facilities immediately due and payable if an event of default occurs and is continuing and the lenders holding a majority of such outstanding debt request the acceleration of the debt.

We intend to defend ourselves vigorously against these allegations and to continue operating in compliance with the terms and conditions of each of EFH’s, TCEH’s and their respective affiliates’ debt agreements, including the TCEH Senior Secured Credit Facilities.
