Business And Significant Accounting Policies	BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES Description of Business References in this report to "we," "our," "us" and "the company" are to EFCH and/or its subsidiaries, as apparent in the context. See "Glossary" for defined terms. EFCH, a wholly owned subsidiary of EFH Corp., is a Dallas, Texas-based holding company. In April 2013, EFCH was converted from a Texas corporation to a Delaware limited liability company. The conversion did not result in a change in the management, assets, businesses or operations of EFCH. We conduct our operations almost entirely through our wholly owned subsidiary, TCEH. TCEH is a holding company for subsidiaries engaged in competitive electricity market activities largely in Texas, including electricity generation, wholesale energy sales and purchases, commodity risk management and trading activities and retail electricity sales. Key management activities, including commodity risk management and electricity sourcing for our retail and wholesale customers, are performed on an integrated basis; consequently, there are no reportable business segments. TCEH operates largely in the ERCOT market, and wholesale electricity prices in that market have generally moved with the price of natural gas. Wholesale electricity prices have significant implications to TCEH's profitability and cash flows and, accordingly, the value of its business. Liquidity Considerations EFCH has been and is expected to continue to be adversely affected by the sustained decline in natural gas prices and its effect on wholesale and retail electricity prices in ERCOT. Further, the remaining natural gas hedges that TCEH entered into when forward market prices of natural gas were significantly higher than current prices will mature in 2013 and 2014. These market conditions challenge the long-term profitability and operating cash flows of EFCH's and its subsidiaries' business and the ability to support their significant interest payments and debt maturities, and could adversely impact their ability to obtain additional liquidity and service, refinance and/or extend the maturities of their outstanding debt. Note 5 provides the details of debt activity in 2013 and the principal amounts and maturity dates of EFCH's and its consolidated subsidiaries' short-term borrowings and long-term debt, which includes the maturity of $3.8 billion of the TCEH Term Loan Facilities in October 2014. At September 30, 2013, TCEH has $1.3 billion of cash and cash equivalents and $171 million of available capacity under its letter of credit facility. Based on forward wholesale power prices in ERCOT, which are subject to the effects of changing market conditions, TCEH may not have sufficient liquidity, absent any financing transactions, to meet its obligations within the next twelve months. EFH Corp. Discussions with Creditors EFH Corp. and its subsidiaries, other than Oncor Holdings and its subsidiaries (the Oncor Ring-Fenced Entities) continue to consider and evaluate possible transactions and initiatives to address their highly leveraged balance sheets and significant cash interest requirements and have entered into discussions with their lenders and bondholders with respect to such transactions and initiatives. These transactions and initiatives may include, among others, debt for debt exchanges, recapitalizations, amendments to and extensions of debt obligations and exchanges or conversions of debt for preferred or common equity or warrants, including exchanges or conversions of debt of EFH Corp., EFIH, EFCH and TCEH into preferred or common equity or warrants of EFH Corp., EFIH, EFCH, TCEH and/or any of their subsidiaries. These actions could result in holders of EFH Corp., EFIH, EFCH and TCEH debt instruments not recovering the full principal amount of those obligations. In March and April 2013, EFH Corp. engaged in discussions with certain unaffiliated holders of first lien senior secured claims against EFCH, TCEH and certain of TCEH's subsidiaries (the TCEH Creditors) with respect to proposed changes to its capital structure. No agreement was reached as part of those discussions, and in September and October 2013, EFH Corp. engaged in further discussions with the TCEH Creditors, certain unaffiliated holders of unsecured claims against EFIH and a significant creditor with claims against TCEH, EFCH, EFIH and EFH Corp. (collectively, the Creditors) with respect to its capital structure, including the possibility of a consensual, prepackaged restructuring transaction. EFH Corp.'s objectives in these discussions were to promote a sustainable capital structure and maximize enterprise value of EFH Corp. and its subsidiaries by, among other things, encouraging agreement on a restructuring plan that would minimize time spent in a restructuring through a proactive and organized solution; minimizing any potential adverse tax impacts of a restructuring; maintaining EFH Corp. in one consolidated group; maintaining focus on operating its businesses, and maintaining EFH Corp.'s high-performing work force. EFH Corp. and the Creditors discussed a number of proposed changes to EFH Corp.'s capital structure. Certain proposals contemplated that some combination of EFH Corp. and certain of its subsidiaries (including EFIH, EFCH and TCEH but excluding the Oncor Ring-Fenced Entities) would implement a plan of reorganization by commencing one or more voluntary cases under Chapter 11 of the United States Bankruptcy Code (the Code). Such proposals would have resulted in a prenegotiated restructuring of EFCH’s approximately $32.2 billion principal amount of debt, EFH Corp.’s approximately $650 million principal amount of debt and EFIH’s approximately $7.6 billion principal amount of debt (each as of September 30, 2013 and excluding debt held by affiliates) and contemplated that after the restructuring EFH Corp. would continue to hold all of the equity interests in EFCH and EFIH; EFCH would continue to hold all of the equity interests in TCEH; and EFIH would continue to hold all of the equity interests in Oncor Holdings. Another proposal contemplated that EFIH (excluding Oncor Holdings and its subsidiaries) would implement a plan of reorganization by commencing a stand-alone voluntary case under the Code. Such proposal contemplated that after the restructuring certain creditors of EFIH would own a substantial majority of, and certain creditors of EFH Corp. and the equity holders of EFH Corp. would collectively own a minority of, the equity interests in EFIH. The confirmation of any plans of reorganization in such cases would be subject to applicable regulatory approvals. EFH Corp. and the Creditors have not reached agreement on the terms of any change in our capital structure. EFH Corp. is not currently engaged in ongoing negotiations with the principals of any of the Creditors. Although the Creditors are not currently engaged in ongoing negotiations with EFH Corp., certain of the Creditors have directed their advisors to continue to work with EFH Corp. and its advisors to explore further whether the parties can reach an agreement on the terms of a consensual restructuring. EFH Corp. will continue to consider and evaluate a range of future changes to its capital structure, in addition to the proposed changes described above, which may include filing a voluntary case under Chapter 11 of the Code for some or all of EFH Corp. and its subsidiaries (excluding the Oncor Ring-Fenced Entities). Basis of Presentation The condensed consolidated financial statements have been prepared in accordance with US GAAP and on the same basis as the audited financial statements included in our 2012 Form 10-K. Adjustments (consisting of normal recurring accruals) necessary for a fair presentation of the results of operations and financial position have been included therein. All intercompany items and transactions have been eliminated in consolidation.

Description of Business

EFCH, a wholly owned subsidiary of EFH Corp., is a Dallas, Texas-based holding company. In April 2013, EFCH was converted from a Texas corporation to a Delaware limited liability company. The conversion did not result in a change in the management, assets, businesses or operations of EFCH. We conduct our operations almost entirely through our wholly owned subsidiary, TCEH. TCEH is a holding company for subsidiaries engaged in competitive electricity market activities largely in Texas, including electricity generation, wholesale energy sales and purchases, commodity risk management and trading activities and retail electricity sales. Key management activities, including commodity risk management and electricity sourcing for our retail and wholesale customers, are performed on an integrated basis; consequently, there are no reportable business segments.

TCEH operates largely in the ERCOT market, and wholesale electricity prices in that market have generally moved with the price of natural gas. Wholesale electricity prices have significant implications to TCEH's profitability and cash flows and, accordingly, the value of its business.

Liquidity Considerations

EFCH has been and is expected to continue to be adversely affected by the sustained decline in natural gas prices and its effect on wholesale and retail electricity prices in ERCOT. Further, the remaining natural gas hedges that TCEH entered into when forward market prices of natural gas were significantly higher than current prices will mature in 2013 and 2014. These market conditions challenge the long-term profitability and operating cash flows of EFCH's and its subsidiaries' business and the ability to support their significant interest payments and debt maturities, and could adversely impact their ability to obtain additional liquidity and service, refinance and/or extend the maturities of their outstanding debt.

Note 5 provides the details of debt activity in 2013 and the principal amounts and maturity dates of EFCH's and its consolidated subsidiaries' short-term borrowings and long-term debt, which includes the maturity of $3.8 billion of the TCEH Term Loan Facilities in October 2014. At September 30, 2013, TCEH has $1.3 billion of cash and cash equivalents and $171 million of available capacity under its letter of credit facility. Based on forward wholesale power prices in ERCOT, which are subject to the effects of changing market conditions, TCEH may not have sufficient liquidity, absent any financing transactions, to meet its obligations within the next twelve months.

EFH Corp. Discussions with Creditors

EFH Corp. and its subsidiaries, other than Oncor Holdings and its subsidiaries (the Oncor Ring-Fenced Entities) continue to consider and evaluate possible transactions and initiatives to address their highly leveraged balance sheets and significant cash interest requirements and have entered into discussions with their lenders and bondholders with respect to such transactions and initiatives. These transactions and initiatives may include, among others, debt for debt exchanges, recapitalizations, amendments to and extensions of debt obligations and exchanges or conversions of debt for preferred or common equity or warrants, including exchanges or conversions of debt of EFH Corp., EFIH, EFCH and TCEH into preferred or common equity or warrants of EFH Corp., EFIH, EFCH, TCEH and/or any of their subsidiaries. These actions could result in holders of EFH Corp., EFIH, EFCH and TCEH debt instruments not recovering the full principal amount of those obligations.

In March and April 2013, EFH Corp. engaged in discussions with certain unaffiliated holders of first lien senior secured claims against EFCH, TCEH and certain of TCEH's subsidiaries (the TCEH Creditors) with respect to proposed changes to its capital structure. No agreement was reached as part of those discussions, and in September and October 2013, EFH Corp. engaged in further discussions with the TCEH Creditors, certain unaffiliated holders of unsecured claims against EFIH and a significant creditor with claims against TCEH, EFCH, EFIH and EFH Corp.

The confirmation of any plans of reorganization in such cases would be subject to applicable regulatory approvals. EFH Corp. and the Creditors have not reached agreement on the terms of any change in our capital structure.

EFH Corp. is not currently engaged in ongoing negotiations with the principals of any of the Creditors.

Basis of Presentation

The condensed consolidated financial statements have been prepared in accordance with US GAAP and on the same basis as the audited financial statements included in our 2012 Form 10-K. Adjustments (consisting of normal recurring accruals) necessary for a fair presentation of the results of operations and financial position have been included therein. All intercompany items and transactions have been eliminated in consolidation. Any acquisitions of outstanding debt for cash, including notes that had been issued in lieu of cash interest, are presented in the financing activities section of the statement of cash flows. Certain information and footnote disclosures normally included in annual consolidated financial statements prepared in accordance with US GAAP have been omitted pursuant to the rules and regulations of the SEC. Because the condensed consolidated interim financial statements do not include all of the information and footnotes required by US GAAP, they should be read in conjunction with the audited financial statements and related notes included in our 2012 Form 10-K. The results of operations for an interim period may not give a true indication of results for a full year. All dollar amounts in the financial statements and tables in the notes are stated in millions of US dollars unless otherwise indicated.

Use of Estimates

Preparation of financial statements requires estimates and assumptions about future events that affect the reporting of assets and liabilities at the balance sheet dates and the reported amounts of revenue and expense, including fair value measurements. In the event estimates and/or assumptions prove to be different from actual amounts, adjustments are made in subsequent periods to reflect more current information.
