Background

Energy Future Holdings Corp. (“EFH Corp.”), Energy Future Competitive Holdings Company LLC (“EFCH”), Texas Competitive Electric Holdings Company LLC (“TCEH”), and Energy Future Intermediate Holding Company LLC (“EFIH” and together with EFH Corp., EFCH and TCEH, the “Companies”) and certain unaffiliated holders of claims against the Companies and certain of their subsidiaries (collectively, the “Creditors”) have executed confidentiality agreements to facilitate the exchange of information and the development of restructuring alternatives. Together with their respective professional advisors, each of the Companies, the Creditors and principals of EFH Corp.’s existing equity holders (the “Equity Holders”) are engaged in discussions regarding the terms of and conditions to changes in the Companies’ capital structure and restructuring alternatives. The Companies’ objectives in these discussions have been, and continue to be, to promote a sustainable capital structure and maximize enterprise value by, among other things, encouraging agreement among the Creditors on a restructuring plan that would minimize time spent in a restructuring proceeding through a proactive and organized solution; minimizing any potential adverse tax impacts of a restructuring; maintaining focus on operating EFH Corp.’s businesses; and maintaining the Companies’ high-performing work force. Although these discussions have been, and continue to be, constructive with respect to various terms and conditions (including the structure of the restructured Companies), the parties have not executed any agreement in support of changes to the Companies’ capital structure or any restructuring alternatives that are being discussed. There is no guarantee that these discussions will result in an agreement.

Contemporaneously with the discussions described above, TCEH and EFIH have each been negotiating binding commitments with certain financial institutions (collectively, the “DIP Lenders”) for debtor-in-possession financings (collectively, the “DIP Financings”). The proposed DIP Financings would provide for senior secured, super-priority revolving credit facilities and term loans totaling up to $4.475 billion at TCEH and $5.2 billion at EFIH. In addition, as proposed, the TCEH DIP Financing is expected to permit TCEH subsidiary Luminant Mining Company LLC (“Luminant Mining”) to grant the Railroad Commission of Texas (the “RCT”) a collateral bond in an amount equal to or in excess of Luminant Mining’s current reclamation bond obligations.

Given the constructive nature of these ongoing discussions, TCEH has elected not to make certain interest payments due April 1, 2014 and to use the permitted grace periods with respect to the TCEH Secured Notes and the Applicable Pollution Control Revenue Bonds (each as defined below). TCEH’s decision of how much of the applicable grace periods to use before pursuing any restructuring alternative (including the filing for protection under Chapter 11 of the US Bankruptcy Code) will be evaluated based on various factors, including the status of the discussions described above.

Notwithstanding the matters described in this Current Report, during the pendency of the discussions described above, the Companies expect to continue to operate their businesses in the ordinary course and meet their ordinary course obligations (i.e., trade, supplier/vendor, trading counterparty and similar obligations), but not TCEH’s funded debt obligations described herein, as they become due and payable. At March 25, 2014, cash and cash equivalents totaled $763 million, consisting of $197 million at EFH Corp., $137 million at EFIH and $429 million at TCEH.

Concurrently with the filing of this Current Report, EFH, EFIH and EFCH have filed an extension request on Form 12b-25 with the Securities Exchange Commission with respect to the filing of their respective Annual Reports on Form 10-K.

TCEH Secured Notes

In light of the ongoing discussions described above, TCEH and TCEH Finance, Inc. (together with TCEH, the “Issuer”) elected not to pay the following interest payments due April 1, 2014:

Both the Indenture, dated as of April 19, 2011, relating to the TCEH First Lien Notes (the “TCEH First Lien Notes Indenture”), and the Indenture, dated October 6, 2010, as supplemented, relating to the TCEH Second Lien Notes (the “TCEH Second Lien Notes Indenture”), provide for a 30-day grace period for interest payments before an event of default may be deemed to have occurred. If the interest payment on either the TCEH First Lien Notes or the TCEH Second Lien Notes is not made and TCEH does not file for Chapter 11 protection prior to the expiration of the applicable grace period, then either the trustee under the TCEH First Lien Notes Indenture or the trustee under the TCEH Second Lien Notes Indenture, as applicable, or the holders of not less than 30% in aggregate principal amount of the TCEH First Lien Notes or the TCEH Second Lien Notes, as applicable, may declare the entire principal amount of the applicable TCEH Secured Notes and the interest accrued thereon to be due and payable immediately. The current principal amount outstanding of the TCEH First Lien Notes is $1.75 billion, and the current principal amount outstanding of the TCEH Second Lien Notes is $1.571 billion.

An event of default under the TCEH First Lien Notes that results in the acceleration of or right to accelerate the debt outstanding thereunder would constitute an event of default under the TCEH Second Lien Notes, and an event of default under the TCEH Second Lien Notes that results in the acceleration of or right to accelerate the debt outstanding thereunder would constitute an event of default under the TCEH First Lien Notes. An event of default under the TCEH First Lien Notes or the TCEH Second Lien Notes that results in the acceleration of or right to accelerate the debt outstanding thereunder would also constitute an event of default or otherwise trigger the acceleration of (or the right to accelerate) repayment obligations under a number of material direct financial obligations of EFCH and its subsidiaries, including the debt instruments listed below:

Pollution Control Revenue Bonds

In light of the ongoing discussions described above, TCEH elected not to pay an aggregate of approximately $10.1 million in interest due April 1, 2014 under the following pollution control revenue bonds (the “Applicable Pollution Control Revenue Bonds”):

The indentures governing the Applicable Pollution Control Revenue Bonds provide for a 60-day grace period for interest payments before an event of default may be deemed to have occurred. If the interest payments on the Applicable Pollution Control Revenue Bonds are not made prior to the expiration of the grace period on May 30, 2014, then the trustee under the relevant series of Applicable Pollution Control Revenue Bonds may, or upon the request of the holders of at least 25% in aggregate principal amount of the relevant series of Applicable Pollution Control Revenue Bonds will, declare the entire principal amount of the relevant series of the Applicable Pollution Control Revenue Bonds and the interest accrued thereon to be due and payable immediately. The current principal amount outstanding of the Applicable Pollution Control Revenue Bonds is $289 million. The Applicable Pollution Control Revenue Bonds are non-recourse with respect to Brazos River Authority and Sabine River Authority.

An event of default under the Applicable Pollution Control Revenue Bonds that results in the acceleration of or right to accelerate the debt outstanding thereunder would constitute an event of default or otherwise trigger the acceleration of (or the right to accelerate) repayment obligations under a number of material direct financial obligations of EFCH and its subsidiaries (either due to a direct cross-default with the Applicable Pollution Control Revenue Bonds or due to a cross-default with other debt that has a direct cross-default with the Applicable Pollution Control Revenue Bonds) , including the TCEH Secured Notes, the TCEH Credit Agreement, the TCEH First Lien Commodity Hedges, the TCEH First Lien Interest Rate Hedges, the TCEH 10.25% Unsecured Notes and the TCEH Unsecured Toggle Notes.
