GLOSSARY

When the following terms and abbreviations appear in the text of this report, they have the meanings indicated below.

2011 Form 10-K	EFIH's Annual Report on Form 10-K for the year ended December 31, 2011
Adjusted EBITDA	Adjusted EBITDA means EBITDA adjusted to exclude noncash items, unusual items and other adjustments allowable under the EFIH Notes and certain debt arrangements of EFH Corp. (as applicable). See definition of EBITDA below. Adjusted EBITDA and EBITDA are not recognized terms under US GAAP and, thus, are non-GAAP financial measures. We are providing our and EFH Corp.'s Adjusted EBITDA in this Form 10-Q (see reconciliations in Exhibits 99(b) and 99(c)) solely because of the important role that Adjusted EBITDA plays in respect of certain covenants contained in the indentures for the EFIH Notes and EFH Corp. debt pushed down to EFIH as discussed in Note 4 to Financial Statements. We do not intend for Adjusted EBITDA (or EBITDA) to be an alternative to net income as a measure of operating performance or an alternative to cash flows from operating activities as a measure of liquidity or an alternative to any other measure of financial performance presented in accordance with US GAAP. Additionally, we do not intend for Adjusted EBITDA (or EBITDA) to be used as a measure of free cash flow available for management's discretionary use, as the measure excludes certain cash requirements such as interest payments, tax payments and other debt service requirements.

ENERGY FUTURE INTERMEDIATE HOLDING COMPANY LLC

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

1. BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES

Description of Business

References in this report to "we," "our," "us" and "the company" are to EFIH and/or its direct and indirect subsidiaries as apparent in the context. See "Glossary" for defined terms.

EFIH is a Dallas, Texas-based holding company whose wholly-owned subsidiary, Oncor Holdings, holds a majority interest (approximately 80%) in Oncor. Oncor is a regulated electricity transmission and distribution company principally engaged in providing delivery services to REPs, including subsidiaries of TCEH, that sell electricity to residential, business and other consumers in the north-central, eastern and western parts of Texas. EFIH is a direct, wholly-owned subsidiary of EFH Corp. EFIH has no reportable business segments. Oncor Holdings and its subsidiaries are not consolidated in EFIH's financial statements in accordance with consolidation accounting standards related to variable interest entities (VIEs) (see Note 2).

Various "ring-fencing" measures have been taken to enhance the credit quality of Oncor Holdings and Oncor. These measures serve to mitigate Oncor's and Oncor Holdings' credit exposure to the Texas Holdings Group, which includes EFIH, and to reduce the risk that the assets and liabilities of Oncor or Oncor Holdings would be substantively consolidated with the assets and liabilities of the Texas Holdings Group in the event of a bankruptcy of one or more of Texas Holding Group's subsidiaries. Such measures include, among other things: Oncor's sale of a 19.75% equity interest to Texas Transmission in November 2008; maintenance of separate books and records for the Oncor Ring-Fenced Entities; the board of directors of Oncor Holdings and Oncor being comprised of a majority of independent directors, and prohibitions on the Oncor Ring-Fenced Entities' providing credit support to, or receiving credit support from, any member of the Texas Holdings Group. The assets and liabilities of the Oncor Ring-Fenced Entities are separate and distinct from those of the Texas Holdings Group, including TXU Energy and Luminant, and none of the assets of the Oncor Ring-Fenced Entities are available to satisfy the debt or contractual obligations of any member of the Texas Holdings Group. Oncor and Oncor Holdings do not bear any liability for debt or contractual obligations of the Texas Holdings Group (including, but not limited to, our debt obligations), and vice versa. Accordingly, Oncor Holdings' operations are conducted, and its cash flows managed, independently from the Texas Holdings Group.

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 2011 Form 10-K. Our investment in Oncor Holdings does not meet accounting standards criteria for consolidation and is accounted for under the equity method (see Note 2). 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. 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 2011 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 income 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.

2. INVESTMENT IN ONCOR HOLDINGS

We have an equity investment in Oncor Holdings, which holds an approximate 80% interest in Oncor. Oncor Holdings is considered a variable interest entity (VIE). A VIE is an entity with which we have a relationship or arrangement that indicates some level of control over the entity or results in economic risks to us. Accounting standards require consolidation of a VIE if we have (a) the power to direct the significant activities of the VIE and (b) the right or obligation to absorb profit and loss from the VIE (primary beneficiary). In determining the appropriateness of consolidation of a VIE, we evaluate its purpose, governance structure, decision making processes and risks that are passed on to its interest holders. We also examine the nature of any related party relationships among the interest holders of the VIE and the nature of any special rights granted to the interest holders of the VIE.

We do not consolidate Oncor Holdings and instead account for it as an equity method investment because the structural and operational "ring-fencing" measures discussed in Note 1 prevent us from having power to direct the significant activities of Oncor Holdings or Oncor. In accordance with accounting standards, we account for our investment in Oncor Holdings under the equity method, as opposed to the cost method, based on our level of influence over its activities.

The carrying value of our variable interest in Oncor Holdings totaled $5.870 billion and $5.720 billion at September 30, 2012 and December 31, 2011, respectively, and is reported as investment in Oncor Holdings in the balance sheet. Our maximum exposure to loss from this investment does not exceed our carrying value.

See Note 7 for discussion of Oncor Holdings' and Oncor's transactions with EFH Corp. and its other subsidiaries.

Distributions from Oncor Holdings —Oncor Holdings' distributions of earnings to us totaled $100 million and $64 million in the nine months ended September 30, 2012 and 2011, respectively. Distributions are limited to Oncor's cumulative net income and may not be paid except to the extent Oncor maintains a required regulatory capital structure, as discussed below. At September 30, 2012, $218 million was eligible to be distributed to Oncor's members after taking into account these restrictions, of which approximately 80% relates to our ownership interest in Oncor. The boards of directors of each of Oncor and Oncor Holdings can withhold distributions to the extent the applicable board determines in good faith that it is necessary to retain such amounts to meet expected future requirements of Oncor and/or Oncor Holdings.

For the period beginning October 11, 2007 and ending December 31, 2012, distributions (other than distributions of the proceeds of any equity issuance) paid by Oncor to its members are limited by a PUCT order to an amount not to exceed Oncor's cumulative net income determined in accordance with US GAAP, as adjusted. Adjustments consist of the removal of noncash impacts of purchase accounting and deducting two specific cash commitments. To date, the noncash impacts consist of removing the effect of an $860 million goodwill impairment charge in 2008 and the cumulative amount of net accretion of fair value adjustments. The two specific cash commitments are the $72 million ($46 million after tax) one-time refund to customers in September 2008 and the funds spent as part of the $100 million commitment for additional energy efficiency initiatives of which $94 million ($61 million after tax) has been spent through September 30, 2012. At September 30, 2012, $468 million was available for distribution under the cumulative net income restriction, of which approximately 80% relates to our ownership interest in Oncor.

Oncor's distributions are further limited by its regulatory capital structure, which is required to be at or below the assumed debt-to-equity ratio established periodically by the PUCT for ratemaking purposes, which is currently set at 60% debt to 40% equity. At September 30, 2012, Oncor's regulatory capitalization ratio was 58.5% debt and 41.5% equity. The PUCT has the authority to determine what types of debt and equity are included in a utility's debt-to-equity ratio. For purposes of this ratio, debt is calculated as long-term debt plus unamortized gains on reacquired debt less unamortized issuance expenses, premiums and losses on reacquired debt. The debt calculation excludes bonds issued by Oncor Electric Delivery Transition Bond Company, which were issued in 2003 and 2004 to recover specific generation-related regulatory asset stranded and other qualified costs. Equity is calculated as membership interests determined in accordance with US GAAP, excluding the effects of accounting for the Merger (which included recording the initial goodwill and fair value adjustments and the subsequent related impairments and amortization). At September 30, 2012, $218 million was available for distribution under the capital structure restriction, of which approximately 80% relates to our ownership interest in Oncor.

3. INVESTMENTS IN LONG-TERM DEBT OF AFFILIATES

As a result of debt exchanges in 2009 through 2011, we hold debt securities of EFH Corp. and TCEH with carrying values totaling $4.283 billion and $3.632 billion at September 30, 2012 and December 31, 2011, respectively, reported as investments in long-term debt of affiliates.

At September 30, 2012 and December 31, 2011, all of these debt securities are classified as available-for-sale because management has determined it would sell or exchange the securities under certain conditions. The EFH Corp. and TCEH securities were reclassified to available-for-sale from held-to-maturity in the third quarter 2011 and fourth quarter 2010, respectively. Any sale or exchange of these securities to/with nonaffiliates would require EFH Corp. to facilitate the transaction. In accordance with accounting guidance for investments classified as available-for-sale, at September 30, 2012 and December 31, 2011 the securities are recorded at fair value and unrealized gains or losses are recorded in other comprehensive income unless such losses are other than temporary, in which case they are recorded as impairments in net income. The principal amounts, coupon rates, maturities and carrying value are as follows:

	September 30, 2012					December 31, 2011
	Principal Amount		Carrying Value (a)			Principal Amount		Carrying Value (a)
Available-for-sale securities:
EFH Corp. 10.875% Fixed Senior Notes due November 1, 2017	$	1,591	$	1,447		$	1,591	$	1,288

Cumulative unrealized gains (recorded as other comprehensive income) (b)			(480		)			(61		)
Amortized cost basis (c)			$	3,803				$	3,571

_____________

(a) Carrying value equals fair value.

(b) 2012 amount reflects unrealized gains on all EFH Corp. securities. 2011 amount reflects unrealized gain on EFH Corp. Toggle Notes.

(c) 2012 amount is net of impairments in 2010 through 2012 totaling $100 million. 2011 amount is net of impairments in 2010 and 2011 totaling $94 million.

Total interest income related to available-for-sale securities	152			—			462			6
Total interest income	$	152		$	160		$	462		$	463

Impairment — During the quarter ended September 2012, we deemed the declines in values of the TCEH securities were other than temporary and recorded a $6 million impairment, which is reported as a reduction of interest income. We considered that the securities were in a loss position for nine months and the effects of low wholesale power prices on the profitability and cash flows of TCEH (which has below investment grade credit ratings) were unlikely to reverse in the near term.

We determine value under the fair value hierarchy established in accounting standards. Under the fair value hierarchy, Level 2 valuations are based on evaluated prices that reflect observable market information, such as actual trade information of similar securities, adjusted for observable differences. The fair value of our investment in long-term debt of affiliates is estimated at the lesser of either the call price or the market value as determined by broker quotes and quoted market prices for similar securities in active markets. For the periods presented, the fair values of our investment in long-term debt of affiliates represent Level 2 valuations. At September 30, 2012, unaffiliated parties held 14% of the outstanding EFH Corp. Toggle Notes and 11% of the outstanding EFH Corp 10.875% Notes; EFIH held the remaining outstanding notes.

Our liquidity needs represent interest and principal payments on our long-term debt, which we expect to fund with interest and principal payments we receive on the investments in TCEH and EFH Corp. debt securities, distributions we receive from Oncor Holdings and as necessary, additional liquidity sources including borrowings from EFH Corp. The indentures governing the EFIH Notes do not limit our ability to dividend the EFH Corp. debt securities that we hold to EFH Corp. so long as we received such securities in exchange for the issuance of EFIH debt, which applies to all the EFH Corp. debt we currently hold, and we may dividend a portion of the securities to EFH Corp. in the future.

Issuances of EFIH 6.875% Senior Secured Notes in 2012

In October 2012, EFIH and EFIH Finance issued $253 million principal amount of 6.875% Senior Secured Notes due 2017 (EFIH 6.875% Notes) with the proceeds used for general corporate purposes, which may include the payment of dividends to EFH Corp. The offering was issued at a premium of $8 million, which will be amortized to interest expense over the life of the notes. In August 2012, EFIH and EFIH Finance issued $250 million principal amount of EFIH 6.875% Notes and $600 million principal amount of 11.75% Senior Secured Second Lien Notes due 2022 (EFIH 11.75% Notes). The EFIH 11.75% Notes are discussed further below. Of the net proceeds from the August 2012 issuances, $680 million was retained in cash and placed in escrow (and is reported as restricted cash in the balance sheet) to be dividended to EFH Corp. by January 2013, and EFH Corp. agreed to use the dividend and cash on hand to repay the balance of the demand notes payable by EFH Corp. to TCEH, which totaled $689 million at September 30, 2012.

The EFIH 6.875% Notes mature in August 2017, with interest payable in cash semiannually in arrears on February 15 and August 15, beginning February 15, 2013, at a fixed rate of 6.875% per annum. The EFIH 6.875% Notes are secured on a first-priority basis by EFIH's pledge of its 100% ownership of the membership interests in Oncor Holdings (the EFIH Collateral) on an equal and ratable basis with the EFIH 9.75% Notes, the EFIH 10% Notes and EFIH's guarantee of the EFH Corp. Secured Notes.

Until February 15, 2015, EFIH may redeem, with the net cash proceeds of certain equity offerings, up to 35% of the aggregate principal amount of the EFIH 6.875% Notes from time to time at a redemption price of 106.875% of the aggregate principal amount of the notes being redeemed, plus accrued interest. EFIH may redeem the notes at any time prior to February 15, 2015 at a price equal to 100% of their principal amount, plus accrued interest and the applicable premium as defined in the indenture governing the notes. EFIH may also redeem the notes, in whole or in part, at any time on or after February 15, 2015, at specified redemption prices, plus accrued interest. Upon the occurrence of a change of control (as described in the indenture governing the notes), EFIH must offer to repurchase the notes at 101% of their principal amount, plus accrued interest.

10

The EFIH 6.875% Notes were issued in private placements and are not registered under the Securities Act. EFIH has agreed to use its commercially reasonable efforts to register with the SEC notes having substantially identical terms as the EFIH 6.875% Notes (except for provisions relating to transfer restrictions and payment of additional interest) as part of an offer to exchange freely tradable notes for the EFIH 6.875% Notes. If the registration statement has not been filed and declared effective within 365 days after the date the initial EFIH 6.875% Notes were issued (a Registration Default), the annual interest rate on the notes will increase by 25 basis points for the first 90-day period during which a Registration Default continues, and thereafter, the annual interest rate on the notes will increase by 50 basis points for the remaining period during which the Registration Default continues. If the Registration Default is cured, the interest rate on the notes will revert to the original level.

Issuances of EFIH 11.75% Senior Secured Second Lien Notes in 2012

In February and August 2012, EFIH and EFIH Finance issued $1.150 billion and $600 million principal amount of EFIH 11.75% Notes, respectively. The February 2012 offerings were issued at a discount of $12 million, and the August 2012 offering was issued at a premium of $14 million, both of which will be amortized to interest expense over the life of the notes. The net proceeds from the February 2012 issuance were used to pay a $950 million dividend to EFH Corp., and the balance was retained as cash on hand. EFH Corp. used the dividend to repay a portion of the demand notes payable by EFH Corp. to TCEH.

The EFIH 11.75% Notes mature in March 2022, with interest payable in cash semiannually in arrears on March 1 and September 1 at a fixed rate of 11.75% per annum. The EFIH 11.75% Notes are secured on a second-priority basis by the EFIH Collateral on an equal and ratable basis with the EFIH 11% Notes. The EFIH 11.75% Notes have substantially the same covenants as the EFIH 11% Notes, and the holders of the EFIH 11.75% Notes will generally vote as a single class with the holders of the EFIH 11% Notes.

Until March 1, 2015, EFIH may redeem, with the net cash proceeds of certain equity offerings, up to 35% of the aggregate principal amount of the EFIH 11.75% Notes from time to time at a redemption price of 111.750% of the aggregate principal amount of the notes being redeemed, plus accrued interest. EFIH may redeem the notes at any time prior to March 1, 2017 at a price equal to 100% of their principal amount, plus accrued interest and the applicable premium as defined in the indenture governing the notes. EFIH may also redeem the notes, in whole or in part, at any time on or after March 1, 2017, at specified redemption prices, plus accrued interest. Upon the occurrence of a change of control (as described in the indenture governing the notes), EFIH must offer to repurchase the notes at 101% of their principal amount, plus accrued interest.

The EFIH 11.75% Notes were issued in private placements and are not registered under the Securities Act. EFIH has agreed to use its commercially reasonable efforts to register with the SEC notes having substantially identical terms as the EFIH 11.75% Notes (except for provisions relating to transfer restrictions and payment of additional interest) as part of an offer to exchange freely tradable notes for the EFIH 11.75% Notes. If the registration statement has not been filed and declared effective within 365 days after the date the initial EFIH 11.75% notes were issued (a Registration Default), the annual interest rate on the notes will increase by 25 basis points for the first 90-day period during which a Registration Default continues, and thereafter, the annual interest rate on the notes will increase by 50 basis points for the remaining period during which the Registration Default continues. If the Registration Default is cured, the interest rate on the notes will revert to the original level.

Guarantees and Push Down of EFH Corp. Debt

Merger-related debt of EFH Corp. and its subsidiaries consists of debt issued or existing at the time of the Merger. Debt issued in exchange for Merger-related debt is considered Merger-related. Debt issuances are considered Merger-related debt to the extent the proceeds are used to repurchase Merger-related debt. Merger-related debt of EFH Corp. (parent) that is fully and unconditionally guaranteed on a joint and several basis by EFCH and EFIH is subject to push down in accordance with SEC Staff Accounting Bulletin Topic 5-J, and as a result, a portion of such debt and related interest expense is reflected in our financial statements. Merger-related debt of EFH Corp. held as an investment by its subsidiaries is not subject to push down.

The amount reflected in our balance sheet as pushed down debt ($721 million and $709 million at September 30, 2012 and December 31, 2011, respectively, as shown in the long-term debt table above) represents 50% of the principal amount (plus unamortized premium) of the EFH Corp. Merger-related debt guaranteed by EFIH. This percentage reflects the fact that at the time of the Merger, the equity investments of EFCH and EFIH in their respective operating subsidiaries were essentially equal amounts. Because payment of principal and interest on the debt is the responsibility of EFH Corp., we record the settlement of such amounts as noncash capital contributions from EFH Corp. (see Note 8).

The tables below present, at September 30, 2012 and December 31, 2011, an analysis of the total outstanding principal amount of EFH Corp. debt that EFIH and EFCH have guaranteed (fully and unconditionally on a joint and several basis), as (i) amounts that EFIH held as an investment, (ii) amounts held by nonaffiliates subject to push down to our balance sheet and (iii) amounts held by nonaffiliates that are not Merger-related. The EFCH guarantee of the EFH Corp. debt is not secured. EFIH's guarantee of the EFH Corp. Secured Notes is secured by the EFIH Collateral.

EFIH 9.75% Senior Secured Notes

At September 30, 2012, the principal amount of the EFIH 9.75% Notes totaled $141 million. The notes mature in October 2019, with interest payable in cash semi-annually in arrears on April 15 and October 15 at a fixed rate of 9.75% per annum. The EFIH 9.75% Notes are not guaranteed but are secured by the EFIH Collateral on an equal and ratable basis with the EFIH 6.875% Notes, the EFIH 10% Notes and EFIH's guarantee of the EFH Corp. Secured Notes.

The notes are senior obligations of EFIH and rank equally in right of payment with all senior indebtedness of EFIH and are senior in right of payment to any future subordinated indebtedness of EFIH. The notes are effectively senior to all unsecured indebtedness of EFIH, to the extent of the value of the EFIH Collateral, and are effectively subordinated to any indebtedness of EFIH secured by assets of EFIH other than the EFIH Collateral, to the extent of the value of such assets. Furthermore, the notes are structurally subordinated to all indebtedness and other liabilities of EFIH's subsidiaries (other than EFIH Finance), including Oncor Holdings and its subsidiaries.

EFIH 10% Senior Secured Notes

At September 30, 2012, the principal amount of the EFIH 10% Notes totaled $2.180 billion. The notes mature in December 2020, with interest payable in cash semi-annually in arrears on June 1 and December 1 at a fixed rate of 10% per annum. The notes are secured by the EFIH Collateral on an equal and ratable basis with the EFIH 6.875% Notes, the EFIH 9.75% Notes and EFIH's guarantee of the EFH Corp. Senior Secured Notes as discussed above.

EFIH 11% Senior Secured Second Lien Notes

At September 30, 2012, the principal amount of the EFIH 11% Notes totaled $406 million. The notes mature in October 2021, with interest payable in cash semiannually in arrears on May 15 and November 15 at a fixed rate of 11% per annum. The notes are secured on a second-priority basis by the EFIH Collateral on an equal and ratable basis with the EFIH 11.75% Notes.

The EFIH 11% Notes were issued in a private placement and are not registered under the Securities Act. EFIH agreed to use its commercially reasonable efforts to register with the SEC notes having substantially identical terms as the EFIH 11% Notes (except for provisions relating to transfer restrictions and payment of additional interest) as part of an offer to exchange freely tradable notes for the EFIH 11% Notes, unless such notes meet certain transferability conditions (as described in the related registration rights agreement). The notes met the transferability conditions in March 2012 and became freely tradable.

Fair Value of Long-Term Debt

At September 30, 2012 and December 31, 2011, the estimated fair value of our long-term debt (including pushed down debt) totaled $5.874 billion and $3.494 billion, respectively, and the carrying amount totaled $5.451 billion and $3.436 billion, respectively. We determine fair value in accordance with accounting standards and at September 30, 2012 represents Level 2 valuations. We obtain security pricing from a vendor who uses broker quotes and third-party pricing services to determine fair values. Where relevant, these prices are validated through subscription services such as Bloomberg.

Guarantees

See Notes 4 and 7 as well as Note 5 to Financial Statements in our 2011 Form 10-K for discussion of our guarantees of certain EFH Corp. debt.

Legal Proceedings

From time to time, we may be involved in various legal and administrative proceedings in the normal course of business the ultimate resolutions of which, in the opinion of management, should not have a material effect upon our financial condition, results of operations or liquidity.

6. MEMBERSHIP INTERESTS

Distribution Restrictions

The indentures governing the EFIH Notes include covenants that, among other things and subject to certain exceptions, restrict our ability to pay dividends or make other distributions with respect to our membership interests. Accordingly, our net income is restricted from being used to make distributions with respect to our membership interests unless such distributions are expressly permitted under the indentures. The indentures further restrict us from making any distribution to EFH Corp. for the ultimate purpose of making a dividend on EFH Corp.'s common stock unless at the time, and after giving effect to such distribution, our consolidated leverage ratio is equal to or less than 6.0 to 1.0. Under the indentures governing the EFIH Notes, the term "consolidated leverage ratio" is defined as the ratio of EFIH's consolidated total debt (as defined in the indentures) to EFIH's Adjusted EBITDA on a consolidated basis, including Oncor Holdings and its subsidiaries. EFIH's consolidated leverage ratio was 6.3 to 1.0 at September 30, 2012.

In addition, under applicable law, we are prohibited from paying any distribution to the extent that immediately following payment of such distribution, we would be insolvent.

In February 2012, EFIH's board of directors declared, and EFIH paid a cash dividend to EFH Corp. of $950 million, which was used by EFH Corp. to partially settle a demand note payable to TCEH (see Note 4). EFIH did not declare or pay any cash distributions in the nine months ended September 30, 2011.

7. RELATED–PARTY TRANSACTIONS

The following represent our significant related-party transactions in addition to the investment in EFH Corp. and TCEH debt securities discussed in Note 3:

• EFH Corp. files consolidated federal income tax and Texas state margin tax returns, and under a tax sharing agreement, allocates income tax liabilities to us substantially as if we were filing our own corporate income tax returns. Our amounts payable to EFH Corp. related to income taxes totaled $1 million and $119 million at September 30, 2012 and December 31, 2011, respectively. The income tax payable at September 30, 2012 was reported as current since cash and projected cash interest income from investments in long-term debt of affiliates and distributions from Oncor Holdings are expected to be sufficient to cover interest payments on our debt and current income tax payable. The income tax payable at December 31, 2011 was reported as noncurrent because we did not expect to pay it until mid-2013, and we have the ability to defer such payments. Our income tax payments to EFH Corp. totaled $172 million and $30 million in the nine months ended September 30, 2012 and 2011, respectively. See discussion below in this note regarding allocation of income tax liabilities to Oncor Holdings and Oncor.

• At September 30, 2012 and December 31, 2011, EFH Corp. had demand notes payable to TCEH totaling $689 million and $1.592 billion, respectively, arising from borrowings used to fund EFH Corp. debt principal and interest payments (P&I Note) and net borrowings for general corporate purposes (SG&A Note). The reduction in the balance of the notes in the nine months ended September 30, 2012 was funded by debt issued by EFIH, and EFH Corp. agreed to settle the balance of the notes by January 2013 with the proceeds from EFIH and EFIH Finance debt issuances in August 2012 (see Note 4). The notes are guaranteed by EFCH and EFIH on an unsecured basis. In connection with debt-related transactions entered into by EFH Corp. in April 2011, EFH Corp. agreed (i) to not make any additional borrowings under the SG&A Note, which totaled $233 million at September 30, 2012, (ii) to cap borrowings under the P&I Note to no more than $2 billion and (iii) that the sum of (a) the outstanding debt (including guarantees) of EFH Corp. or any of its subsidiaries (including EFIH) that is secured by a second-priority lien on the equity interest that EFIH owns in Oncor Holdings (the EFIH Second-Priority Debt) and (b) the aggregate outstanding amount of the intercompany notes will not exceed, at any time, the maximum amount of EFIH Second-Priority Debt permitted by the indenture governing the EFH Corp. 10% Senior Secured Notes due 2020.

• In the nine months ended September 30, 2012, fees paid to Goldman, Sachs & Co. (Goldman), an affiliate of GS Capital Partners, related to debt issuances totaled $10 million, described as follows: (i) Goldman acted as a joint book-running manager and initial purchaser in the February 2012 issuance of $1.150 billion principal amount of EFIH 11.750% Senior Secured Second Lien Notes (see Note 4) for which it received fees totaling $7 million; (ii) Goldman acted as joint book-running manager and initial purchaser in the August 2012 issuance of $600 million principal amount of 11.750% Senior Secured Second Lien Notes and $250 million principal amount of EFIH 6.875% Senior Secured Notes (see Note 4) for which it received fees totaling $3 million. In the October 2012 issuance of $253 million EFIH 6.875% Notes, Goldman acted as joint book-running manager and initial purchaser for which it was paid $1 million. A broker-dealer affiliate of KKR served as a co-manager and initial purchaser and an affiliate of TPG Management, L.P. (TPG) served as an advisor in all of these transactions, for which they each received a total of $4 million.

• Affiliates of the Sponsor Group have sold or acquired, and in the future may sell or acquire, debt or debt securities issued by us in open market transactions or through loan syndications.

See Note 4 regarding guarantees and push-down of certain EFH Corp. debt and Note 6 regarding noncash settlement of certain income taxes payable.

Significant related-party transactions between Oncor Holdings (including its consolidated subsidiary Oncor) and EFH Corp., other affiliates of EFH Corp. and the Sponsor Group are as follows:

• Oncor receives payments from TCEH for services it provides, principally the delivery of electricity. Revenues recorded by Oncor for these services totaled $281 million and $309 million in the three months ended September 30, 2012 and 2011, respectively, and $746 million and $798 million in the nine months ended September 30, 2012 and 2011, respectively. The fees are based on rates regulated by the PUCT that apply to all REPs. These revenues from TCEH represented 29% and 34% of Oncor Holdings' operating revenues in the nine months ended September 30, 2012 and 2011, respectively. Oncor Holdings' balance sheets at September 30, 2012 and December 31, 2011 reflect receivables from TCEH totaling $154 million and $138 million, respectively, primarily related to these electricity delivery fees.

• In August 2012, TCEH and Oncor agreed to settle at a discount two agreements related to securitization (transition) bonds issued by Oncor's bankruptcy-remote financing subsidiary in 2003 and 2004 to recover generation-related regulatory assets. Under the agreements, TCEH had been reimbursing Oncor as described immediately below. Under the settlement, TCEH paid, and Oncor received, $159 million in cash. The settlement was executed by EFIH acquiring the right to reimbursement under the agreements from Oncor and then selling these rights for the same amount to TCEH. The transaction resulted in a decrease of approximately $2 million (after tax) in Oncor's membership interests in the three months ended September 30, 2012 in accordance with accounting rules for related party transactions. Accordingly, the transaction resulted in a decrease of approximately $1 million (reflecting our 80% interest in Oncor) in our investment in unconsolidated subsidiary with an offsetting decrease in equity.

Under an interest reimbursement agreement, TCEH has reimbursed Oncor on a monthly basis for interest expense on the transition bonds. The remaining interest to be paid through 2016 under the agreement totaled $53 million at the settlement date. Only the monthly accrual of interest under this agreement was reported as a receivable by Oncor. This interest income totaled $2 million and $8 million in the three months ended September 30, 2012 and 2011, respectively, and $16 million and $24 million in the nine months ended September 30, 2012 and 2011, respectively.

Oncor collects transition surcharges from its customers to recover the transition bond payment obligations. Oncor's incremental income taxes related to the transition surcharges it collects have been reimbursed by TCEH quarterly under a noninterest bearing note payable to Oncor maturing in 2016. The note balance at the settlement date totaled $159 million.

• Oncor pays EFH Corp. subsidiaries for certain administrative services and shared facilities at cost. These costs, which are primarily reported in operation and maintenance expenses, totaled $10 million and $10 million in the three months ended September 30, 2012 and 2011, respectively, and $27 million and $28 million in the nine months ended September 30, 2012 and 2011, respectively.

• Under Texas regulatory provisions, the trust fund for decommissioning the Comanche Peak nuclear generation facility is funded by a delivery fee surcharge collected from REPs by Oncor and remitted monthly to TCEH, with the intent that the trust fund assets (reported in TCEH's balance sheet) will be sufficient to fund the decommissioning liability (also reported in TCEH's balance sheet). The delivery fee surcharges remitted to TCEH totaled $5 million in each of the three month periods ended September 30, 2012 and 2011 and $12 million and $13 million in the nine months ended September 30, 2012 and 2011, respectively. Income and expenses associated with the trust fund and the decommissioning liability recorded by TCEH are offset by a net change in the intercompany receivable/payable between Oncor and TCEH, which in turn results in a change in Oncor's reported net regulatory asset/liability. The regulatory liability and a receivable from TCEH in the same amount, which totaled $286 million and $225 million at September 30, 2012 and December 31, 2011, respectively, represent the excess of the trust fund balance over the net decommissioning liability.

• EFH Corp. files a consolidated federal income tax return that includes Oncor Holdings' results. Oncor is not a member of EFH Corp.'s consolidated tax group, but EFH Corp.'s consolidated federal income tax return includes EFH Corp.'s portion of Oncor's results as a result of EFH Corp.'s equity ownership in Oncor. EFH Corp. also files a consolidated Texas state margin tax return that includes all of Oncor Holdings' and Oncor's results. However, under a tax sharing agreement Oncor Holdings and Oncor record their federal income and Texas state margin taxes substantially as if Oncor Holdings and Oncor were filing their own corporate income tax returns. Oncor Holdings and Oncor had a current combined payable to EFH Corp. related to income taxes of $17 million and $2 million at September 30, 2012 and December 31, 2011, respectively. Oncor Holdings and Oncor made income tax net payments to EFH Corp. totaling $27 million and received income tax net refunds from EFH Corp totaling $89 million in the nine months ended September 30, 2012 and 2011, respectively.

• Oncor has PUCT-approved tariffs in place to assure adequate credit worthiness of any REP to support the REP's obligation to collect transition bond-related charges on behalf of Oncor Electric Delivery Transition Bond Company LLC. Under these tariffs, as a result of TCEH's credit rating being below investment grade, TCEH is required to post collateral support in an amount equal to estimated transition charges over specified time periods. Accordingly, at September 30, 2012 and December 31, 2011, TCEH had posted letters of credit in the amount of $11 million and $12 million, respectively, for Oncor's benefit.

• Oncor and Texas Holdings agreed to the terms of a stipulation with major interested parties to resolve all outstanding issues in the PUCT review related to the Merger. As part of this stipulation, TCEH would be required to post a letter of credit in an amount equal to $170 million to secure its payment obligations to Oncor in the event, which has not occurred, two or more rating agencies downgrade Oncor's credit rating below investment grade.

• Affiliates of the Sponsor Group have, and from time-to-time in the future, may (1) sell, acquire or participate in the offerings of Oncor's debt or debt securities in open market transactions or through loan syndications, and (2) perform various financial advisory, dealer, commercial banking and investment banking services for Oncor and certain of its affiliates for which they have received or will receive customary fees and expenses.

• Oncor participates in plans sponsored by EFH Corp. that provide pension, health care and other retiree benefits. Accordingly, Oncor Holdings' consolidated financial statements reflect allocations to Oncor of amounts related to these retiree benefit plans. Certain regulatory provisions allow for the recovery by Oncor of retiree benefit costs for all applicable former employees of EFH Corp.'s regulated predecessor integrated electric utility, which in addition to Oncor's active and retired employees consists largely of active and retired personnel engaged in TCEH's activities, related to service of those additional personnel prior to the deregulation and disaggregation of EFH Corp.'s businesses effective January 1, 2002. Accordingly, Oncor and TCEH entered into an agreement whereby Oncor assumed responsibility for applicable retiree benefit costs related to those personnel.

In August 2012, EFH Corp. approved certain amendments to its pension plan. These amendments will result, in part, in the splitting off of the assets and liabilities under the plan associated with employees of Oncor and all retirees and terminated vested employees of EFH Corp. and its subsidiaries (including discontinued businesses) to a new plan that is expected to be sponsored and administered by Oncor (the Oncor Plan). These actions are expected to be completed in the fourth quarter 2012. In connection with this action, EFH Corp. intends to fully fund the obligations being assumed by the Oncor Plan that relate to participants' benefits not recoverable by Oncor. Transition to and implementation of the Oncor Plan is not expected to materially affect Oncor's reported results of operations, financial condition or cash flows.

Item 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis of our financial condition and results of operations for the three and nine months ended September 30, 2012 and 2011 should be read in conjunction with our consolidated financial statements and the notes to those statements.

All dollar amounts in the tables in the following discussion and analysis are stated in millions of US dollars unless otherwise indicated.

Business

EFIH is a Dallas, Texas-based holding company whose wholly-owned subsidiary, Oncor Holdings, holds a majority interest (approximately 80%) in Oncor. Oncor is a regulated electricity transmission and distribution company principally engaged in providing delivery services to REPs, including subsidiaries of TCEH, that sell electricity to residential, business and other consumers in the north-central, eastern and western parts of Texas. Revenues from TCEH represented 29% and 34% of Oncor's total revenues in the nine months ended September 30, 2012 and 2011, respectively. EFIH is a direct, wholly-owned subsidiary of EFH Corp. EFIH has no reportable business segments. See Notes 1 and 2 to Financial Statements for a discussion of the reporting of our investment in Oncor Holdings as an equity method investment and a description of the "ring-fencing" measures implemented with respect to Oncor Holdings and Oncor. These measures were put in place to further enhance Oncor's credit quality and mitigate Oncor's and Oncor Holdings' exposure to the Texas Holdings Group with the intent to minimize the risk that a court would order any of the Oncor Ring-Fenced Entities' assets and liabilities to be substantively consolidated with those of any member of the Texas Holdings Group in the event any such member were to become a debtor in a bankruptcy case. We believe, as several major credit rating agencies have acknowledged, that the likelihood of such substantive consolidation of Oncor's or Oncor Holdings' assets and liabilities is remote in consideration of the ring-fencing measures and applicable law.

Significant Activities and Events

Issuance of $2.253 Billion of Senior Secured Notes — See Note 4 to Financial Statements for details of EFIH's and EFIH Finance's issuance in October 2012, August 2012 and February 2012 of an aggregate $1.750 billion principal amount of 11.750% Senior Secured Second Lien Notes due 2022 and an aggregate $503 million principal amount of 6.875% Senior Secured Notes due 2017.

EFH Corp. and EFIH regularly evaluate potential opportunities to improve our balance sheets through transactions that extend debt maturities or reduce the amount of our debt or our cash interest expense. Future activities under this liability management program may include, among others, the purchase of our outstanding debt for cash in open market purchases or privately negotiated refinancing, extension and exchange transactions (including pursuant to a Rule 10b-5(1) plan) or via public or private exchange or tender offers. Such transactions may include the acquisition of EFH Corp. or other affiliate debt by EFIH and the acquisition of EFIH or other affiliate debt by EFH Corp.

Oncor Technology Initiatives — Oncor continues to invest in technology initiatives that include development of a modernized grid through the replacement of existing meters with advanced digital metering equipment and development of advanced digital communication, data management, real-time monitoring and outage detection capabilities. This modernized grid is producing electricity service reliability improvements and providing the potential for additional products and services from REPs that enable businesses and consumers to better manage their electricity usage and costs. Oncor's plans provide for the full deployment of over three million advanced meters to all residential and most non-residential retail electricity customers in Oncor's service area. The advanced meters can be read remotely, rather than by a meter reader physically visiting the location of each meter. Advanced meters facilitate automated demand side management, which allows consumers to monitor the amount of electricity they are consuming and adjust their electricity consumption habits.

At September 30, 2012, Oncor had installed 3,104,000 advanced digital meters, including 802,000 in 2012. As the new meters are integrated, Oncor reports 15-minute interval, billing-quality electricity consumption data to ERCOT for market settlement purposes. The data makes it possible for REPs to support new programs and pricing options. Cumulative capital expenditures for the deployment of the advanced meter system totaled $642 million at September 30, 2012, including $124 million in 2012. Oncor expects to complete installations of the advanced meters by the end of 2012.

19

Oncor Matters with the PUCT —Competitive Renewable Energy Zones (CREZs) — In 2009, the PUCT awarded Oncor CREZ construction projects (PUCT Docket Nos. 35665 and 37902) requiring 14 related Certificate of Convenience and Necessity (CCN) amendment proceedings before the PUCT for 17 projects. All 17 projects and 14 CCN amendments have been approved by the PUCT. The projects involve the construction of transmission lines and stations to support the transmission of electricity from renewable energy sources, principally wind generation facilities, in the western part of Texas to population centers in the eastern part of Texas. In addition to these projects, ERCOT completed a study in December 2010 that will result in Oncor and other transmission service providers building additional facilities to provide further voltage support to the transmission grid as a result of CREZ. Oncor currently estimates, based on these additional voltage support facilities and the approved routes and stations for its awarded CREZ projects, that CREZ construction costs will total approximately $2.0 billion. CREZ-related costs could change based on finalization of costs for the additional voltage support facilities and final detailed designs of subsequent project routes. At September 30, 2012, Oncor's cumulative CREZ-related capital expenditures totaled $1.360 billion, including $461 million in 2012. Oncor expects that all necessary permitting actions and other requirements and all line and station construction activities for Oncor's CREZ construction projects will be completed by the end of 2013 with additional voltage support projects completed by early 2014.

Transmission Cost Recovery and Rates(PUCT Docket Nos. 40451, 39940, 40603 and 40142)—In order to reflect increases or decreases in its wholesale transmission costs, including fees paid to other transmission service providers, Oncor is allowed to update the transmission cost recovery factor (TCRF) component of its retail delivery rates charged to REPs twice a year. In June 2012, Oncor filed an application to update the TCRF, which became effective September 1, 2012. This application was designed to increase Oncor's revenues for the period from September 2012 through February 2013 by $129 million. In November 2011, Oncor filed an application to update the TCRF, which was approved by the PUCT in January 2012 and became effective in March 2012. This application was designed to lower Oncor's revenues for the period from March 2012 through August 2012 by $41 million, reflecting over-recoveries due to hot weather in the summer of 2011.

In July 2012, Oncor filed an application for an interim update of its wholesale transmission rate. The new rate was approved by the PUCT and became effective in August 2012. Oncor's annualized revenues are expected to increase by an estimated $30 million with approximately $19 million of this increase recoverable through transmission costs charged to wholesale customers and $11 million recoverable from REPs through the TCRF component of Oncor's delivery rates. In January 2012, Oncor filed an application for an interim update of its wholesale transmission rate. The new rate was approved by the PUCT and became effective in March 2012. Oncor's annualized revenues are expected to increase by an estimated $2 million with approximately 65% of this increase recoverable through transmission costs charged to wholesale customers and the remaining 35% recoverable from REPs through the TCRF component of Oncor's delivery rates.

Stipulation Approved by the PUCT (PUCT Docket No. 34077) —In April 2008, the PUCT entered an order, which became final in June 2008, approving the terms of a stipulation relating to a filing in 2007 by Oncor and Texas Holdings with the PUCT pursuant to Section 14.101(b) of the Texas Public Utility Regulatory Act and PUCT Substantive Rule 25.75. Among other things, the stipulation required Oncor to file a rate review no later than July 1, 2008 based on a test year ended December 31, 2007, which Oncor filed in June 2008. The PUCT issued a final order with respect to the rate review in August 2009. In July 2008, Nucor Steel filed an appeal of the PUCT's order in the 200^th District Court of Travis County, Texas (District Court). A hearing on the appeal was held in June 2010, and the District Court affirmed the PUCT order in its entirety. Nucor Steel appealed that ruling to the Texas Third Court of Appeals (Austin Court of Appeals) in July 2010. In March 2012, the Austin Court of Appeals affirmed the District Court's ruling, which is now final.

Application for 2013 Energy Efficiency Cost Recovery Factor(PUCT Docket No. 40361) — In May 2012, Oncor filed an application with the PUCT to request approval of an energy efficiency cost recovery factor (EECRF) for 2013. PUCT rules require Oncor to make an annual EECRF filing by the first business day in May for implementation at the beginning of the next calendar year. The requested 2013 EECRF is $73 million as compared to $54 million established for 2012, and would result in a monthly charge for residential customers of $1.23 as compared to the 2012 residential charge of $0.99 per month effective December 31, 2012. In August 2012, the PUCT issued a final order approving the 2013 EECRF, which is designed to recover $62 million of Oncor's costs for the 2013 program year, a $9 million performance bonus based on Oncor's 2011 results and a $2 million increase for under-recovery of 2011 costs.

Summary—We cannot predict future regulatory or legislative actions or any changes in economic and securities market conditions. Such actions or changes could significantly affect our results of operations, liquidity or financial condition.

RESULTS OF OPERATIONS

Financial Results — Three Months Ended September 30, 2012 Compared to Three Months Ended September 30, 2011

Interest income decreased $8 million to $152 million in 2012. The decrease reflected a $6 million impairment charge related to the decline in fair value of our investment in TCEH securities (see Note 3 to Financial Statements).

Interest expense and related charges increased $49 million to $137 million in 2012. The increase reflected the issuances of $1.150 billion aggregate principal amount of EFIH Notes in February 2012 and $850 million aggregate principal amount of EFIH Notes in August 2012 (see Note 4 to Financial Statements).

Income tax expense totaled $6 million and $25 million in 2012 and 2011, respectively. The effective rate on pretax income was 40.0% and 34.7% in 2012 and 2011, respectively. The increase in the effective rate reflected the recognition in 2011 of previously nondeductible interest on pushed down debt due to a debt exchange transaction, and an increase in Texas margin tax due to an increase in the apportionment factor.

Equity in earnings of our Oncor Holdings unconsolidated subsidiary (net of tax) decreased $4 million to $109 million in 2012 reflecting lower earnings at Oncor due to the effect of milder weather on revenues and higher interest and depreciation expense, partially offset by higher tariffs.

Net income decreased $42 million to $118 million in 2012 driven by the increase in interest expense.

Financial Results — Nine Months Ended September 30, 2012 Compared to Nine Months Ended September 30, 2011

Interest income decreased $1 million to $462 million in 2012.

Interest expense and related charges increased $109 million to $368 million in 2012. The increase reflected the issuance of $850 million, $1.150 billion and $406 million aggregate principal amount of EFIH Notes in August 2012, February 2012 and April 2011, respectively (see Note 4 to Financial Statements and Note 5 to Financial Statements in our 2011 Form 10-K Financial Statements).

Income tax expense totaled $35 million and $72 million in 2012 and 2011, respectively. The effective rate on pretax income was 37.2% and 35.3% in 2012 and 2011, respectively. The increase in the effective rate reflected the recognition in 2011 of previously nondeductible interest on pushed down debt due to a debt exchange transaction.

Equity in earnings of our Oncor Holdings unconsolidated subsidiary (net of tax) increased $14 million to $249 million in 2012 reflecting higher earnings at Oncor due to higher tariffs, partially offset by the effect of milder weather on revenues and higher depreciation, operation and maintenance and interest expense.

Net income decreased $59 million to $308 million in 2012 driven by the increase in interest expense.

FINANCIAL CONDITION

Liquidity and Capital Resources

Cash Flows —Nine Months Ended September 30, 2012 Compared to Nine Months Ended September 30, 2011— Cash used in operating activities totaled $196 million in 2012 compared to $1 million in 2011. The $195 million increase reflected $142 million in higher income taxes paid to EFH Corp. (including amounts related to prior periods) and $101 million in higher cash interest paid, partially offset by $36 million in higher cash distributions from Oncor Holdings. See Note 7 to Financial Statements for discussion of income tax payments to EFH Corp.

Amortization of debt issuance costs reported in the statement of consolidated cash flows represents the expenses related to debt pushed down from EFH Corp. and debt we issued (see Note 4 to Financial Statements) and is reported in interest expense and related charges in the statement of consolidated income.

21

Cash provided by financing activities totaled $1.0 billion in 2012, reflecting the net proceeds from EFIH's issuances of $2 billion of EFIH Notes and distributions of $950 million of the proceeds to EFH Corp. (see Note 4 to Financial Statements).

Cash used in investing activities totaled $680 million in 2012 and represented a portion of the net proceeds from the issuance of EFIH notes in August 2012 that EFIH placed in escrow (reported as restricted cash) to pay a dividend in this amount to EFH Corp. by January 2013 (see Note 4 to Financial Statements). There were no cash flows related to investing activities in 2011.

Liquidity Needs — Our liquidity needs represent interest and principal payments on our long-term debt and payments of income taxes to EFH Corp., which we expect to fund with interest and principal payments we receive on the investments in EFH Corp. or TCEH debt securities (see Note 3 to Financial Statements), distributions we receive from Oncor Holdings, and as necessary, additional liquidity sources including borrowings from EFH Corp. (See "Distributions from Oncor" below and Notes 2 and 7 to Financial Statements.)

Secured Debt Capacity—At October 26, 2012, we believe that we and EFH Corp. collectively are permitted under our applicable debt agreements to issue (subject to certain exceptions and conditions set forth in our applicable debt documents) up to approximately $700 million of additional aggregate principal amount of debt secured by EFIH's equity interest in Oncor Holdings on a second-priority basis.

These amounts are estimates based on our current interpretation of the covenants set forth in our applicable debt agreements and do not take into account exceptions in the debt agreements that may allow for the incurrence of additional secured debt, including, but not limited to, acquisition debt, coverage ratio debt, refinancing debt, capital leases and hedging obligations. Moreover, such amounts could change from time to time as a result of, among other things, the termination of any debt agreement (or specific terms therein) or amendments to the debt agreements that result from negotiations with new or existing lenders. In addition, covenants included in agreements governing additional future debt may impose greater restrictions on our incurrence of secured debt. Consequently, the actual amount of senior secured debt that we are permitted to incur under our debt agreements could be materially different than the amounts provided above.

Toggle Notes Interest Election Related to EFH Corp. Debt Held as an Investment and Pushed Down EFH Corp. Debt — EFH Corp. has the option every six months at its discretion, ending with the payment due November 2012, to use the payment-in-kind (PIK) feature of its EFH Corp. Toggle Notes in lieu of making cash interest payments. EFH Corp. elected to do so beginning with the May 2009 interest payment as an efficient and cost-effective method to further enhance liquidity. Once EFH Corp. makes a PIK election, the election is valid for each succeeding interest payment period until EFH Corp. revokes the election.

EFH Corp. made its May 2012 interest payment and expects to make its November 2012 interest payment on the EFH Corp. Toggle Notes by using the PIK feature of those notes. During the applicable interest periods, the interest rate on these notes is increased from 11.25% to 12.00%. Accordingly, we received an aggregate principal amount of EFH Corp. notes totaling $167 million in May 2012 and expect to receive and additional $177 million in November 2012 in lieu of cash interest on our investment in EFH Corp. Toggle Notes. Also as a result of the PIK feature, EFH Corp. issued an additional $26 million aggregate principal amount of the notes to nonaffiliates in May 2012 and is expected to issue an additional $28 million in November 2012, all of which are subject to push down to our balance sheet. See Notes 3 and 4 to Financial Statements.

Distributions of Earnings from Oncor Holdings —Oncor Holdings' distributions of earnings to us totaled $100 million and $64 million in the nine months ended September 30, 2012 and 2011, respectively. We expect to receive a distribution totaling approximately $47 million from Oncor Holdings on October 30, 2012. See Note 2 to Financial Statements for discussion of limitations on amounts Oncor can distribute to its members.

In 2009, the PUCT awarded certain CREZ construction projects to Oncor. See discussion above under "Significant Activities and Events — Oncor Matters with the PUCT." As a result of the increased capital expenditures for CREZ and the debt-to-equity ratio cap, our distributions from Oncor could be substantially reduced or temporarily discontinued during the CREZ construction period, which is expected to be largely completed by the end of 2013.

22

Financial Covenants, Credit Rating Provisions and Cross Default Provisions —Covenants and Restrictions Related to EFIH Notes and Pushed Down Debt—The indentures governing the EFIH Notes, EFH Corp. 10.875% Notes, EFH Corp. Toggle Notes and EFH Corp. Secured Notes contain covenants that could have a material impact on our liquidity and operations. See Note 4 to Financial Statements for discussion of our long-term debt, including EFH Corp. debt pushed down to us as a result of our guarantee of the debt.

Adjusted EBITDA (as used in the restricted payments covenants contained in the indentures governing the EFIH Notes and the EFH Corp. Secured Notes) in the twelve months ended September 30, 2012 totaled $1.723 billion and $5.258 billion, respectively. See Exhibits 99(b) and 99(c) for a reconciliation of net income (loss) to Adjusted EBITDA for EFIH and EFH Corp., respectively, in the nine and twelve months ended September 30, 2012 and 2011.

The table below summarizes various financial ratios of EFIH and EFH Corp. that are applicable under certain threshold covenants in the indentures governing the EFIH Notes, EFH Corp. 10.875% Notes, EFH Corp. Toggle Notes and EFH Corp. Secured Notes at September 30, 2012 and December 31, 2011 and the corresponding covenant threshold levels at September 30, 2012. The debt incurrence and restricted payments/limitations on investments covenants thresholds described below represent levels that must be met in order for EFH Corp. and EFIH to incur certain permitted debt or make certain restricted payments and/or investments. Our debt agreements do not contain maintenance covenants.

	September 30, 2012	December 31, 2011	Threshold Level at September 30, 2012
Debt Incurrence Covenants:
EFH Corp. Secured Notes:
EFH Corp. fixed charge coverage ratio	1.0 to 1.0	1.1 to 1.0	At least 2.0 to 1.0
EFIH Notes:
EFIH fixed charge coverage ratio (a)	(b)	(b)	At least 2.0 to 1.0
Restricted Payments/Limitations on Investments Covenants:
EFH Corp. 10.875% Notes and Toggle Notes:
General restrictions (Sponsor Group payments):
EFH Corp. leverage ratio	9.6 to 1.0	9.7 to 1.0	Equal to or less than 7.0 to 1.0
EFH Corp. Secured Notes:
General restrictions (non-Sponsor Group payments):
EFH Corp. fixed charge coverage ratio (c)	1.4 to 1.0	1.4 to 1.0	At least 2.0 to 1.0
General restrictions (Sponsor Group payments):
EFH Corp. fixed charge coverage ratio (c)	1.0 to 1.0	1.1 to 1.0	At least 2.0 to 1.0
EFH Corp. leverage ratio	9.6 to 1.0	9.7 to 1.0	Equal to or less than 7.0 to 1.0
EFIH Notes:
General restrictions (non-EFH Corp. payments):
EFIH fixed charge coverage ratio (a)(d)	6.6 to 1.0	81.7 to 1.0	At least 2.0 to 1.0
General restrictions (EFH Corp. payments):
EFIH fixed charge coverage ratio (a)(d)	(b)	(b)	At least 2.0 to 1.0
EFIH leverage ratio	6.3 to 1.0	5.3 to 1.0	Equal to or less than 6.0 to 1.0

_____________

(a) Although we currently meet the fixed charge coverage ratio threshold applicable to certain covenants contained in the indentures governing the EFIH Notes, our ability to use such thresholds to incur debt or make restricted payments/investments is currently limited by the covenants contained in indentures governing the EFH Corp. 10.875% Notes, EFH Corp. Toggle Notes and EFH Corp. Secured Notes.

(b) We meet the ratio threshold. Because our interest income exceeds interest expense, the result of the ratio calculation is not meaningful.

(c) The EFH Corp. fixed charge coverage ratio for non-Sponsor Group payments includes the results of Oncor Holdings and its subsidiaries. The EFH Corp. fixed charge coverage ratio for Sponsor Group payments excludes the results of Oncor Holdings and its subsidiaries.

(d) The EFIH fixed charge coverage ratio for non-EFH Corp. payments includes the results of Oncor Holdings and its subsidiaries. The EFIH fixed charge coverage ratio for EFH Corp. payments excludes the results of Oncor Holdings and its subsidiaries.

Material Cross Default/Acceleration Provisions — Certain of our financing arrangements contain provisions that could result in an event of default if there were a failure under other financing arrangements to meet payment terms or to observe other covenants that could or does result in an acceleration of payments due. Such provisions are referred to as "cross default" or "cross acceleration" provisions.

The indentures governing the EFIH Notes contain a cross acceleration provision whereby a payment default at maturity or on acceleration of principal indebtedness under any instrument or instruments of EFIH or any of its restricted subsidiaries or of any debt that EFIH guarantees in an aggregate amount equal to or greater than $250 million may cause the acceleration of the EFIH Notes.

The indentures governing the EFH Corp. Secured Notes contain a cross acceleration provision whereby a payment default at maturity or on acceleration of principal indebtedness under any instrument or instruments of EFH Corp. or any of its restricted subsidiaries (including EFIH) in an aggregate amount equal to or greater than $250 million may cause the acceleration of the EFH Corp. Secured Notes.

CHANGES IN ACCOUNTING STANDARDS

There have been no recently issued accounting standards effective after September 30, 2012 that are expected to materially impact our financial statements.

Item 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market risk is the risk that we may experience a loss in value as a result of changes in market conditions such as interest rates that may be experienced in the ordinary course of business. We may transact in financial instruments to hedge interest rate risk related to our debt, but there are currently no such hedges in place. All of our long-term debt at September 30, 2012 and December 31, 2011 carried fixed interest rates.

Except as discussed below, the information required hereunder is not significantly different from the information set forth in "Item 7A. Quantitative and Qualitative Disclosures About Market Risk" included in our 2011 Form 10-K and is therefore not presented herein.

Credit Risk

We are exposed to affiliate credit risk associated with the $4.596 billion principal amount of EFH Corp. debt securities and $79 million principal amount of TCEH debt securities we hold as investments (see Note 3 to Financial Statements). The credit rating of each of these securities is below investment grade. The carrying value of these securities was $4.283 billion at September 30, 2012.

Oncor's Credit Risk — Credit risk relates to the risk of loss associated with nonperformance by counterparties. Oncor's customers consist primarily of REPs. As a prerequisite for obtaining and maintaining certification, a REP must meet the financial resource standards established by the PUCT. Meeting these standards does not guarantee that a REP will be able to perform its obligations. REP certificates granted by the PUCT are subject to suspension and revocation for significant violation of Texas Public Utility Regulatory Act and PUCT rules. Significant violations include failure to timely remit payments for invoiced charges to a transmission and distribution utility pursuant to the terms of tariffs approved by the PUCT. PUCT rules allow for the recovery of uncollectible amounts from nonaffiliated REPs, reducing the credit risk of such receivables.

At September 30, 2012, Oncor's exposure to credit risk associated with accounts receivable totaled $154 million from affiliates, substantially all of which consisted of trade accounts receivable from TCEH, and $377 million from nonaffiliated customers. The nonaffiliated customer receivable amount is before the allowance for uncollectible accounts, which totaled $2 million at September 30, 2012. The nonaffiliate exposure includes trade accounts receivable from REPs totaling $289 million, which are almost entirely noninvestment grade. At September 30, 2012, REP subsidiaries of one nonaffiliated entity collectively represented approximately 14% of the nonaffiliated trade receivable amount. No other nonaffiliated parties represented 10% or more of the total exposure.

See Note 7 to Financial Statements for discussion of transactions between Oncor and TCEH and EFH Corp.

FORWARD-LOOKING STATEMENTS

This report and other presentations made by us contain "forward-looking statements." All statements, other than statements of historical facts, that are included in this report, or made in presentations, in response to questions or otherwise, that address activities, events or developments that we expect or anticipate to occur in the future, including such matters as projections, capital allocation, future capital expenditures, business strategy, competitive strengths, goals, future acquisitions or dispositions, development or operation of facilities, market and industry developments and the growth of our business and operations (often, but not always, through the use of words or phrases such as "intends," "plans," "will likely," "expected," "anticipated," "estimated," "should," "projection," "target," "goal," "objective" and "outlook"), are forward-looking statements. Although we believe that in making any such forward-looking statement our expectations are based on reasonable assumptions, any such forward-looking statement involves uncertainties and is qualified in its entirety by reference to the discussion of risk factors under Item 1A, "Risk Factors" in this report, our quarterly report on Form 10-Q for the quarterly period ended June 30, 2012 and our 2011 Form 10-K and the discussion under Item 2, "Management's Discussion and Analysis of Financial Condition and Results of Operations" in this report and the following important factors, among others, that could cause our actual results to differ materially from those projected in such forward-looking statements:

• prevailing governmental policies and regulatory actions, including those of the Texas Legislature, the Governor of Texas, the US Congress, the US Federal Energy Regulatory Commission, the NERC, the TRE, the PUCT, the EPA, and the Texas Commission on Environmental Quality, with respect to, among other things:

◦ allowed rate of return;

◦ permitted capital structure;

◦ industry, market and rate structure;

◦ recovery of investments;

◦ acquisition and disposal of assets and facilities;

◦ operation and construction of facilities;

◦ changes in tax laws and policies, and

◦ changes in and compliance with environmental and safety laws and policies;

• legal and administrative proceedings and settlements;

• general industry trends;

• economic conditions, including the impact of a recessionary environment;

• weather conditions, including drought and limitations on access to water, and other natural phenomena, and acts of sabotage, wars or terrorist or cybersecurity threats or activities;

• unanticipated population growth or decline, or changes in market supply or demand and demographic patterns, particularly in ERCOT;

• changes in business strategy, development plans or vendor relationships;

• unanticipated changes in interest rates or rates of inflation;

• unanticipated changes in operating expenses, liquidity needs and capital expenditures;

• commercial bank and financial market conditions, access to capital, the cost of such capital, and the results of financing and refinancing efforts by EFIH and/or its subsidiaries and affiliates, including availability of funds in the capital markets and the potential impact of disruptions in US credit markets;

• willingness of EFH Corp.'s and TCEH's lenders to extend the maturities of their debt instruments and the terms and conditions of any such extensions;

• activity in the credit default swap market related to our debt securities or debt securities of EFH Corp. that we guarantee;

• inability of various counterparties to meet their financial obligations to EFIH and/or its subsidiaries, including failure of counterparties to perform under agreements;

• changes in technology used by and services offered by EFIH and/or its subsidiaries;

• significant changes in the relationship of EFIH and/or its subsidiaries with their employees, including the availability of qualified personnel, and the potential adverse effects if labor disputes or grievances were to occur;

• changes in assumptions used to estimate costs of providing employee benefits, including medical and dental benefits, pension and other postretirement employee benefits, and future funding requirements related thereto;

• significant changes in critical accounting policies material to EFIH and/or its subsidiaries;

• circumstances that may contribute to impairment of goodwill, intangible or other long-lived assets of EFIH and/or its subsidiaries;

• restrictions imposed by the agreements governing EFIH's, Oncor's and certain of EFH Corp.'s debt instruments;

• our ability to generate sufficient cash flow to make interest payments on our debt instruments;

• defaults under our debt agreements and agreements of EFH Corp. debt that we guarantee that could trigger cross default or cross acceleration provisions under other debt agreements;

• EFH Corp.'s or its subsidiaries', including, in particular, TCEH's, ability to make principal and interest payments on their debt we hold as an investment or to provide sufficient capital contributions or loans to us to make interest payments on our debt instruments;

26

• hazards customary to the industry and the possibility that EFIH and/or its subsidiaries may not have adequate insurance to cover losses resulting from such hazards;

• actions by credit rating agencies;

• adverse claims by our creditors or holders of our debt securities, and

• the ability of EFIH and/or its subsidiaries to effectively execute their operational strategy.

Any forward-looking statement speaks only at the date on which it is made, and except as may be required by law, we undertake no obligation to update any forward-looking statement to reflect events or circumstances after the date on which it is made or to reflect the occurrence of unanticipated events. New factors emerge from time to time, and it is not possible for us to predict all of them; nor can we assess the impact of each such factor or the extent to which any factor, or combination of factors, may cause results to differ materially from those contained in any forward-looking statement. As such, you should not unduly rely on such forward-looking statements.

Item 4. CONTROLS AND PROCEDURES

An evaluation was performed under the supervision and with the participation of our management, including the principal executive officer and principal financial officer, of the effectiveness of the design and operation of the disclosure controls and procedures in effect at the end of the current period included in this quarterly report. Based on the evaluation performed, our management, including the principal executive officer and principal financial officer, concluded that the disclosure controls and procedures were effective. During the most recent fiscal quarter covered by this quarterly report, there has been no change in our internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
