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):

On November 30, 2012, Energy Future Holdings Corp. (“EFH Corp.”) and its subsidiaries, Texas Competitive Electric Holdings Company LLC (“TCEH”) and TXU Energy Retail Company LLC (“TXU Energy”), entered into a new TXU Energy Accounts Receivable Securitization Program (“new AR Program”). In connection with the new AR Program, the parties terminated the existing AR Program. Except as described below, the new AR Program is substantially the same as the terminated AR Program. For a description of the terminated AR Program, see Note 9 to EFH Corp.’s Annual Report on Form 10-K for the year ended December 31, 2011 and Note 5 to EFH Corp.’s Quarterly Report on Form 10-Q for the quarterly period ended September 30, 2012.

The material changes incorporated into the new AR Program are as follows:

A copy of each of the First Lien Trade Receivables Financing Agreement and Trade Receivables Sale Agreement that were entered into as part of the new AR Program is attached hereto as Exhibit 10.1 and 10.2, respectively, and each is incorporated herein by reference. The description of the new AR Program above is qualified in its entirety by reference to such agreements.

The information relating to the new AR Program set forth under Item 1.01 of this Current Report on Form 8-K is incorporated by reference in this Item 2.03.

To facilitate the closing of the new AR Program described above, including the repurchase by TXU Energy of all of its outstanding receivables previously sold under the terminated AR Program and taking into account the cap on the subordinated note under the new AR Program, in November 2012, TCEH borrowed $300 million under its senior secured revolving credit facility (“the “Revolving Credit Facility”). TCEH’s aggregate borrowings under such facility totaled approximately $1.3 billion as of November 30, 2012.

As of November 30, 2012, in addition to the approximately $800 million of available capacity under the Revolving Credit Facility, TCEH had approximately $700 million of cash and cash equivalents and approximately $125 million of available capacity under its senior secured letter of credit facility (the “Letter of Credit Facility”), resulting in aggregate liquidity at TCEH at such date of approximately $1.625 billion. The execution of the new AR Program resulted in a net decrease in aggregate TCEH liquidity at the closing date of approximately $25 million, excluding the payment of transaction fees and expenses.

The Revolving Credit Facility and the Letter of Credit Facility are provided under the Credit Agreement. EFH Corp. has provided information regarding the Credit Agreement in Item 8 of its Annual Report on Form 10-K for the year ended December 31, 2011, and such information is incorporated by reference herein.

Any description of the Credit Agreement is qualified in its entirety by reference to the complete copy of the Credit Agreement filed as Exhibit 10(rr) to EFH Corp.’s Post-Effective Amendment #1 to Form S-4 filed on February 7, 2011, Exhibit 10.1 to EFH Corp.’s Current Report on Form 8-K filed on August 10, 2009, and Exhibit 10.1 to EFH Corp.’s Current Report on Form 8-K filed on April 20, 2011, which complete copy of the Credit Agreement is incorporated by reference herein.
