Description of Business

References in this report to “we,” “our,” “us” and “the company” are to Oncor Holdings and/or its direct or indirect subsidiaries as apparent in the context. The financial statements are comprised almost entirely of the operations of Oncor; consequently, there are no separate reportable business segments. See “Glossary” for definition of terms and abbreviations.

We are a Dallas, Texas-based holding company whose financial statements are comprised almost entirely of the operations of our direct, majority (approximately 80%) owned subsidiary, Oncor. Oncor is a regulated electricity transmission and distribution company principally engaged in providing delivery services to REPs that sell power in the north-central, eastern and western parts of Texas. Revenues from subsidiaries of Vistra (subsidiaries of TCEH until October 3, 2016) represented 23% and 24% of our total operating revenues for the nine months ended September 30, 2017 and 2016, respectively. We are a direct, wholly-owned subsidiary of EFIH, a direct, wholly-owned subsidiary of EFH Corp. EFH Corp. is a subsidiary of Texas Holdings, which is controlled by the Sponsor Group.

Our consolidated financial statements include our former indirect, bankruptcy-remote financing subsidiary, Bondco, a variable interest entity through December 29, 2016, at which time it was dissolved. This financing subsidiary was organized for the limited purpose of issuing certain transition bonds to recover generation-related regulatory asset stranded costs and other qualified costs under an order issued by the PUCT in 2002.

Various “ring-fencing” measures have been taken to enhance the separateness between the Oncor Ring-Fenced Entities and the Texas Holdings Group and our credit quality. These measures serve to mitigate our and Oncor’s credit exposure to the Texas Holdings Group and to reduce the risk that our assets and liabilities or those of Oncor would be substantively consolidated with the assets and liabilities of the Texas Holdings Group in connection with a bankruptcy of one or more of those entities. 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; our board of directors and Oncor’s board of directors 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. 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. We and Oncor do not bear any liability for debt or contractual obligations of the Texas Holdings Group, and vice versa. Accordingly, our operations are conducted, and our cash flows are managed, independently from the Texas Holdings Group.

EFH Corp. Bankruptcy Proceedings

On the EFH Petition Date, the Debtors commenced proceedings under Chapter 11 of the U.S. Bankruptcy Code. The Oncor Ring-Fenced Entities are not parties to the EFH Bankruptcy Proceedings. We believe the “ring-fencing” measures discussed above mitigate our and Oncor’s potential exposure to the EFH Bankruptcy Proceedings. See Note 2 for a discussion of the potential impacts of the EFH Bankruptcy Proceedings on our financial statements.

Basis of Presentation

These unaudited condensed financial statements should be read in conjunction with the audited financial statements and related notes included in our 2016 Audited Financial Statements. In the opinion of Oncor

9

Holdings management, all adjustments (consisting of normal recurring accruals) necessary for a fair presentation of the results of operations and financial position have been made. All intercompany items and transactions have been eliminated in consolidation. The results of operations for an interim period may not give a true indication of results for a full year due to seasonality. All dollar amounts in the financial statements and tables in the notes are stated in millions of U.S. dollars unless otherwise indicated. Subsequent events have been evaluated through November 13, 2017, the date these consolidated financial statements were available to be issued.

Use of Estimates

Preparation of our financial statements requires management to make 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.

Revenue Recognition

General

Oncor’s revenue is billed under tariffs approved by the PUCT and the majority of revenues are related to providing electric delivery service to consumers. Tariff rates are designed to recover the cost of providing electric delivery service including a reasonable rate of return on invested capital. Revenues are generally recognized when the underlying service has been provided in an amount prescribed by the related tariff.

Reconcilable Tariffs

The PUCT has designated certain tariffs (TCRF, EECRF surcharges, AMS surcharges and charges related to transition bonds) as reconcilable, which means the differences between amounts billed under these tariffs and the related incurred costs are deferred as either regulatory assets or regulatory liabilities. Accordingly, at prescribed intervals, future tariffs are adjusted to either repay regulatory liabilities or collect regulatory assets.

Contingencies

We evaluate and account for contingencies using the best information available. A loss contingency is accrued and disclosed when it is probable that an asset has been impaired or a liability incurred and the amount of the loss can be reasonably estimated. If a range of probable loss is established, the minimum amount in the range is accrued, unless some other amount within the range appears to be a better estimate. If the probable loss cannot be reasonably estimated, no accrual is recorded, but the loss contingency is disclosed to the effect that the probable loss cannot be reasonably estimated. A loss contingency will be disclosed when it is reasonably possible that an asset has been impaired or a liability incurred. If the likelihood that an impairment or incurrence is remote, the contingency is neither accrued nor disclosed. Gain contingencies are recognized upon realization.

Changes in Accounting Standards

In February 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2016-2 which created FASB Topic 842, Leases (Topic 842). Topic 842 amends previous GAAP to require the balance sheet recognition of lease assets and liabilities for operating leases. Operating lease liabilities will not be classified as debt for GAAP purposes under Topic 842 and will not be treated as debt for regulatory purposes. At this time, all of Oncor’s existing leases meet the definition of an operating lease liability. Under the new rules, the recognition of any finance leases (currently known as capital leases) on the balance sheet would be classified as debt for GAAP purposes and are expected to be defined as debt for our regulatory capital structure purposes (see Note 8 for details) similar to the current capital lease treatment. We will be required to adopt Topic 842 by

10

January 1, 2019 and do not expect to early adopt. Retrospective application to the 2017 and 2018 comparative periods presented will be required in the year of adoption. The initial adoption of Topic 842 will affect our balance sheet, as leased buildings and vehicles are recognized as operating lease liabilities. Subsequent to adoption, to the extent Oncor enters into finance leases, its credit facility covenants and capitalization ratios could be impacted. We continue to evaluate the potential impact of Topic 842 on our financial statements.

Since May 2014, the FASB has issued ASU No. 2014-09, Revenue from Contracts with Customers along with other supplemental guidance (together, Topic 606). Topic 606 introduces new, increased requirements for disclosure of revenue in financial statements and guidance that are intended to eliminate inconsistencies in the recognition of revenue. We are required to adopt Topic 606 by January 1, 2018 and expect to adopt at that time using the modified retrospective approach. Our revenues from customers are tariff-based and are designed to recover the cost of providing electric delivery service to customers including a reasonable rate of return on invested capital. Revenues are generally recognized when the underlying service has been provided in an amount prescribed by the related tariff. At this time, we do not expect the new guidance to change this pattern of recognition and therefore it is not expected to have a material effect on our reported results of operations, financial position or cash flows. We continue to evaluate the application of the new guidance.

In March 2017, the FASB issued ASU 2017-07 Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost, an amendment to Topic 715, Compensation — Retirement Benefits (Topic 715). Topic 715, as amended, will require the non-service cost components of net retirement benefit plan costs be presented as non-operating in the income statement. In addition, only the service cost component of net retirement benefit plan cost will be eligible for capitalization as part of inventory or property, plant and equipment. We are required to adopt the amendment effective January 1, 2018. The income statement presentation requirement must be applied on a retrospective basis while the capitalization eligibility requirement is applied on a prospective basis. For cash flow purposes on a prospective basis, non-service costs will be reflected as a reduction to operating cash flows, offset by lower cash used in investing activities (lower capital expenditures). At this time, we do not expect the new guidance to have a material effect on our rate-making process, our results of operations, financial position or net change in total cash flows but continue to evaluate for potential impacts.

On the EFH Petition Date, EFH Corp. and the substantial majority of its direct and indirect subsidiaries at the time, including EFIH, EFCH and TCEH, commenced proceedings under Chapter 11 of the U.S. Bankruptcy Code. The Oncor Ring-Fenced Entities are not parties to the EFH Bankruptcy Proceedings. We believe the “ring-fencing” measures discussed above mitigate our and Oncor’s potential exposure to the EFH Bankruptcy Proceedings. See Note 1 and below for further information regarding the EFH Bankruptcy Proceedings and the proposed change in control of our indirect majority owner in connection with such proceedings.

The U.S. Bankruptcy Code automatically enjoined, or stayed, us from judicial or administrative proceedings or filing of other actions against our affiliates or their property to recover, collect or secure our claims arising prior to the EFH Petition Date. Following the EFH Petition Date, EFH Corp. received approval from the bankruptcy court to pay or otherwise honor certain prepetition obligations generally designed to stabilize its operations. Included in the approval were the obligations owed to Oncor representing prepetition electricity delivery fees. Oncor has collected substantially all of the prepetition receivables from the Texas Holdings Group. As discussed below, the 2016 Plan of Reorganization (defined below) provided for a spin-off of the TCEH Debtors from EFH Corp. As a result of this spin-off (Vistra Spin-Off), Vistra and its subsidiaries, including Luminant and TXU Energy, ceased to be affiliates of ours as of October 3, 2016.

The EFH Bankruptcy Proceedings continue to be a complex litigation matter and the full extent of potential impacts on us remain unknown. Bankruptcy courts have broad equitable powers, and as a result, outcomes in bankruptcy proceedings are inherently difficult to predict. We will continue to evaluate our affiliate transactions

11

and contingencies throughout the EFH Bankruptcy Proceedings to determine any risks and resulting impacts on our and Oncor’s results of operations, financial statements and cash flows.

See Note 10 for details of Oncor’s related-party transactions with members of the Texas Holdings Group.

Potential Change in Indirect Ownership of Oncor and Oncor Holdings

Below is a summary of certain matters relating to the potential change in indirect ownership of us and Oncor that may arise as a result of the EFH Bankruptcy Proceedings.

In May 2016, the Debtors filed a joint Plan of Reorganization (2016 Plan of Reorganization) pursuant to Chapter 11 of the U.S. Bankruptcy Code and a related disclosure statement with the bankruptcy court. The 2016 Plan of Reorganization provided that the confirmation and effective date of the 2016 Plan of Reorganization with respect to the TCEH Debtors may occur separate from, and independent of, the confirmation and effective date of the 2016 Plan of Reorganization with respect to the EFH Debtors. In this regard, the bankruptcy court confirmed the 2016 Plan of Reorganization with respect to the TCEH Debtors in August 2016, and it became effective by its terms, and the Vistra Spin-Off occurred, effective October 3, 2016.

Prior Merger Agreements

The following merger agreements relating to a potential change in indirect ownership of us and Oncor were entered into in connection with the EFH Bankruptcy Proceedings. Each of these prior merger agreements has been terminated in accordance with their respective terms.

12

Sempra Merger Agreement

On August 15, 2017, the EFH Debtors received an alternative proposal from Sempra Energy (Sempra) that largely followed the structure of the BHE Plan. Following negotiations, on August 21, 2017, EFH Corp. and EFIH entered into an Agreement and Plan of Merger (Sempra Merger Agreement) with Sempra and one of its wholly-owned subsidiaries (collectively, the Sempra Parties). Similar to the BHE Merger Agreement, the Sempra Merger Agreement does not impose any conditions on the EFH Debtors regarding TTI’s minority interest in Oncor. Accordingly, the Sempra Merger Agreement provides for the acquisition by Sempra of the 80.03% of Oncor’s membership interests owned indirectly by EFH Corp. and EFIH.

Following the execution and delivery of the Sempra Merger Agreement, EFIH requested, pursuant to the Sempra Merger Agreement, that Oncor Holdings and Oncor enter into a letter agreement (Sempra Letter Agreement) with the Sempra Parties. The Sempra Letter Agreement was executed on August 25, 2017 and sets forth certain rights and obligations of the Oncor Ring-Fenced Entities and the Sempra Parties to cooperate in the manner set forth therein with respect to initial steps to be taken in connection with the acquisition of Reorganized EFH and the other transactions described in the Sempra Merger Agreement. Pursuant to the terms of the Sempra Letter Agreement, the Oncor Ring-Fenced Entities are to conduct, in all material respects, their businesses in the ordinary course of business and materially consistent with the plan for 2017 and 2018 contained in Oncor’s long-range business plan. The Sempra Letter Agreement also provides that the Oncor Ring-Fenced Entities will cooperate with the Sempra Parties to prepare and file all necessary applications for governmental approvals of the transactions contemplated by the Sempra Merger Agreement, including PUCT and FERC approvals. The Sempra Letter Agreement is not intended to give the Sempra Parties, directly or indirectly, the right to control or direct the operations of any of the Oncor Ring-Fenced Entities.

In connection with the execution of the Sempra Merger Agreement, on September 5, 2017, the EFH Debtors filed an amended joint plan of reorganization (Sempra Plan) and a related disclosure statement (Sempra Disclosure Statement). On September 6, 2017, the bankruptcy court authorized the EFH Debtors’ entry into the Sempra Merger Agreement, approved the Sempra Disclosure Statement and authorized the EFH Debtors to solicit votes on the Sempra Plan. The Sempra Merger Agreement contemplates that Oncor and the Sempra Parties will file a joint application with the PUCT seeking certain regulatory approvals with respect to the transactions contemplated by the Sempra Plan, and that filing was made on October 5, 2017 in PUCT Docket

13

No. 47675. The EFH Debtors have indicated that they will not seek bankruptcy court confirmation of the Sempra Plan unless and until the PUCT approves the transactions contemplated by the Sempra Plan.

We cannot predict the ultimate outcome of the EFH Bankruptcy Proceedings, including whether the transactions contemplated by the Sempra Plan, including the Sempra Merger Agreement, will (or when they will) close. There remain conditions and uncertainties relating to the Sempra Plan becoming effective and the consummation of the transactions contemplated by the Sempra Merger Agreement, including, without limitation, the ability to obtain required regulatory approvals from the PUCT, as described below under “Regulatory Matters Related to EFH Bankruptcy Proceedings.” As a result, we remain unable to predict how any reorganization of the EFH Debtors ultimately will impact Oncor or what form any change in indirect ownership of Oncor may take. In this regard, we are unable to predict the ultimate impact of the termination of the NEE Merger Agreement and matters relating to the PUCT NEE Plan Order or the TTI Merger Agreement, including the ultimate disposition, if any, of Texas Transmission’s 19.75% equity stake in Oncor.

Regulatory Matters Related to EFH Bankruptcy Proceedings

In September 2015, Oncor and the Hunt Investor Group filed in PUCT Docket No. 45188 a joint application with the PUCT seeking certain regulatory approvals with respect to the transactions contemplated by a plan of reorganization in the EFH Bankruptcy Proceedings. In March 2016, the PUCT issued an order conditionally approving the joint application. In April 2016, the Hunt Investor Group and certain interveners in PUCT Docket No. 45188 filed motions for rehearing and in May 2016, the PUCT denied such motions and the order became final. In May 2016, the plan of reorganization and related merger and purchase agreement that contemplated the transactions in PUCT Docket No. 45188 were terminated. The Hunt Investor Group filed a petition with the Travis County District Court in June 2016 seeking review of the order. We cannot predict the results of the review or the ultimate disposition of PUCT Docket No. 45188, particularly in light of the termination of the Hunt Merger Agreement.

In connection with PUCT Docket No. 45188, certain cities that have retained original jurisdiction over electric utility rates passed resolutions directing Oncor to file rate review proceedings. In connection with those resolutions, counsel for those cities notified Oncor that they expected Oncor to make a rate filing to comply with their resolutions on or before March 17, 2017. That filing was made with the PUCT and original jurisdiction cities on March 17, 2017 in PUCT Docket No. 46957. In July 2017, Oncor and certain parties to the rate review agreed to a settlement of that rate review, and on August 2, 2017 a settlement agreement was filed that settled all issues in the docket. On October 13, 2017, the PUCT issued an order approving the settlement agreement. For more information, see Note 3 — “2017 Rate Review (PUCT Docket No. 46957).”

The NEE Merger Agreement contemplated that Oncor and NEE file a joint application with the PUCT seeking certain regulatory approvals with respect to the transactions contemplated by the Amended EFH Debtor Plan. Oncor and NEE filed that joint application in PUCT Docket No. 46238 in October 2016. The PUCT denied the application on April 13, 2017. The PUCT issued an Order on Rehearing on June 7, 2017 and denied NEE’s Second Motion for Rehearing on June 29, 2017. On July 13, 2017, NEE filed a petition with the Travis County District Court seeking review of the PUCT order. We cannot predict the results of the review or the ultimate disposition of PUCT Docket No. 46238, particularly in light of the termination of the NEE Merger Agreement.

On July 28, 2017, Texas Transmission Holdings Corporation (TTHC) and NEE filed in PUCT Docket No. 47453 a joint application with the PUCT seeking certain regulatory approvals with respect to NEE’s proposed acquisition of the 19.75 percent minority interest in Oncor that is indirectly held by TTHC. The application requested that the PUCT issue an order disclaiming jurisdiction over the transaction or finding that the transaction is in the public interest and approved. On September 14, 2017, Oncor filed a motion to intervene as a party, but not an applicant, in PUCT Docket No. 47453. On October 26, 2017, the PUCT voted to dismiss the application without prejudice on jurisdictional grounds and ordered that any future filing of the application must include the affected utility (in this case Oncor) as an applicant. The PUCT further ordered that in any such

14

filing Oncor is not required to seek approval of the application or any other specific relief. On October 30, 2017, TTHC notified the PUCT that it had terminated the merger agreement with NEE that was the subject of PUCT Docket No. 47453.

Oncor and the Sempra Parties filed a joint application with the PUCT seeking certain regulatory approvals with respect to the transactions contemplated by the Sempra Plan on October 5, 2017 in PUCT Docket No. 47675.

Settlement Agreement

In connection with the EFH Bankruptcy Proceedings, the EFH Debtors and various creditor parties entered into a settlement agreement (the Settlement Agreement) in August 2015 (as amended in September 2015) to compromise and settle, among other things (i) intercompany claims among the EFH Debtors, (ii) claims and causes of actions against holders of first lien claims against TCEH and the agents under the TCEH Senior Secured Facilities, (iii) claims and causes of action against holders of interests in EFH Corp. and certain related entities and (iv) claims and causes of action against each of the EFH Debtors’ current and former directors, the Sponsor Group, managers and officers and other related entities. The Settlement Agreement contemplates a release of such claims upon approval of the Settlement Agreement by the bankruptcy court, which approval was obtained in December 2015.

The Settlement Agreement settles substantially all inter-debtor claims through the effective date of the Settlement Agreement. These settled claims include potentially contentious inter-debtor claims, including various potential avoidance actions and claims arising under numerous debt agreements, tax sharing agreements, and contested property transfers. The release provisions of the Settlement Agreement took effect immediately upon the entry of the bankruptcy court order approving the Settlement Agreement. In this regard, substantially all of the potential affiliate claims, derivative claims and other types of disputes among affiliates (including claims against Oncor) have been resolved by bankruptcy court order. Accordingly, we believe the Settlement Agreement resolves all affiliate claims against Oncor and its assets existing as of the effective date of the Settlement Agreement.

Change in Control Reviews

See “Regulatory Matters Related to EFH Bankruptcy Proceedings” in Note 2.

2017 Rate Review (PUCT Docket No. 46957)

In response to resolutions passed by numerous cities with original jurisdiction over electric utility rates in 2016, Oncor filed rate review proceedings with the PUCT and original jurisdiction cities in our service territory on March 17, 2017 based on a January 1, 2016 to December 31, 2016 test year. In July 2017, Oncor and certain parties to the rate review agreed to a settlement of that rate review, and on August 2, 2017 a settlement agreement was filed that settled all issues in the docket. On October 13, 2017, the PUCT issued an order approving the settlement of the rate review. The order became final and non-appealable on November 7, 2017. The order provides for new rates to take effect on November 27, 2017, contingent upon the closing of the transactions discussed below under “Sharyland Transaction.” The order further provides, among other items, that Oncor’s base rate revenue requirement before intercompany eliminations would be approximately $4.3 billion, Oncor’s authorized return on equity would be 9.8%, and Oncor’s authorized regulatory capital structure would be 57.5% debt and 42.5% equity. Oncor’s current authorized return on equity is 10.25% and the current authorized regulatory capital structure is 60% debt and 40% equity. The order provides for the use of a regulatory liability and bill credit mechanism until the new authorized regulatory capital structure is met following the effective date for new rates to reflect Oncor’s actual capitalization prior to achieving the authorized capital structure.

15

Sharyland Transaction

On July 21, 2017, Oncor entered into an agreement (Sharyland Agreement) with Sharyland Distribution & Transmission Services, L.L.C., a Texas limited liability company (SDTS), Sharyland Utilities, L.P., a Texas limited partnership (SU), and certain of their subsidiaries.

The Sharyland Agreement provides that pursuant to separate mergers (collectively, Sharyland Mergers), (i) Oncor will receive certain of the electricity distribution-related assets and liabilities of SDTS and SU (constituting substantially all of the electricity distribution business of SDTS and SU) and certain transmission assets (collectively, Sharyland Distribution Business and the portion held by SDTS, the SDTS Merger Assets), (ii) SDTS will receive portions of certain of Oncor’s electricity transmission-related assets and liabilities (Oncor Merger Assets) and cash, and (iii) SU will receive cash. The transaction for assets between Oncor and SDTS is structured to qualify, in part, as a simultaneous tax deferred like kind exchange of assets to the extent that the assets exchanged are of “like kind” (within the meaning of Section 1031 of the Internal Revenue Code).

On August 4, 2017, Oncor, SDTS and SU filed a joint application for sale, transfer, or merger in PUCT Docket No. 47469 requesting PUCT approvals of the transactions contemplated by the Sharyland Agreement. On October 13, 2017, the PUCT issued an order approving the Sharyland Agreement in Docket No. 47469. The transactions contemplated by the Sharyland Agreement closed on November 9, 2017. The actual assets exchanged and cash received pursuant to the Sharyland Mergers is based on the difference between the current net book value of the Oncor Merger Assets and/or the actual net book value of the Sharyland Distribution Business as of closing, as provided in the Sharyland Agreement. At closing of the transactions, the net book value of the Oncor Merger Assets was approximately $383 million and the net book value of the SDTS Merger Assets was approximately $401 million. Based on these net book values, Oncor paid SDTS approximately $18 million in cash and SU approximately $7 million in cash.

We do not expect the Sharyland transaction to have a material effect on our and Oncor’s results of operations, financial position or cash flows.

We are involved in various other regulatory proceedings in the normal course of business, the ultimate resolution of which, in the opinion of management, should not have a material effect upon our and Oncor’s financial position, results of operations or cash flows.

See Note 3 to the Financial Statements in our 2016 Audited Financial Statements for additional information regarding regulatory matters.

16

Recognition of regulatory assets and liabilities and the periods which they are to be recovered or refunded through rate regulation are determined by the PUCT. Components of the regulatory assets and liabilities and the remaining periods as of September 30, 2017 are provided in the table below. Amounts not earning a return through rate regulation are noted.

At September 30, 2017, Oncor had a $2.0 billion secured revolving credit facility to be used for working capital and general corporate purposes, issuances of letters of credit and support for any commercial paper issuances. In October 2016, Oncor exercised the second of two one-year extensions available to them and extended the term of the revolving credit facility to October 2018. The terms of the revolving credit facility allow Oncor to request an increase in borrowing capacity of $100 million in the aggregate provided certain conditions are met, including lender approval.

17

Borrowings under the revolving credit facility are classified as short-term on the balance sheet and are secured equally and ratably with all of Oncor’s other secured indebtedness by a first priority lien on property Oncor acquired or constructed for the transmission and distribution of electricity. The property is mortgaged under the Deed of Trust.

At September 30, 2017, Oncor had outstanding borrowings under the revolving credit facility totaling $917 million with an interest rate of 2.22% and outstanding letters of credit totaling $9 million. At December 31, 2016, Oncor had outstanding borrowings under the revolving credit facility totaling $789 million with an interest rate of 1.72% and outstanding letters of credit totaling $7 million.

Borrowings under the revolving credit facility bear interest at per annum rates equal to, at Oncor’s option, (i) LIBOR plus a spread ranging from 1.00% to 1.75% depending on credit ratings assigned to Oncor’s senior secured non-credit enhanced long-term debt or (ii) an alternate base rate (the highest of (1) the prime rate of JPMorgan Chase, (2) the federal funds effective rate plus 0.50%, and (3) daily one-month LIBOR plus 1.00%) plus a spread ranging from 0.00% to 0.75% depending on credit ratings assigned to Oncor’s senior secured non-credit enhanced long-term debt. At September 30, 2017, substantially all outstanding borrowings bore interest at LIBOR plus 1.00%. Amounts borrowed under the revolving credit facility, once repaid, can be borrowed again from time to time.

An unused commitment fee is payable quarterly in arrears and upon termination or commitment reduction at a rate equal to 0.100% to 0.275% (such spread depending on certain credit ratings assigned to Oncor’s senior secured debt) of the daily unused commitments under the revolving credit facility. Letter of credit fees on the stated amount of letters of credit issued under the revolving credit facility are payable to the lenders quarterly in arrears and upon termination at a rate per annum equal to the spread over adjusted LIBOR. Customary fronting and administrative fees are also payable to letter of credit fronting banks. At September 30, 2017, letters of credit bore interest at 1.20%, and a commitment fee (at a rate of 0.10% per annum) was payable on the unfunded commitments under the revolving credit facility, each based on Oncor’s current credit ratings.

Subject to the limitations described below, borrowing capacity available under the revolving credit facility at September 30, 2017 and December 31, 2016 was $1.074 billion and $1.204 billion, respectively. Generally, Oncor’s indentures and revolving credit facility limit the incurrence of other secured indebtedness except for indebtedness secured equally and ratably with the indentures and revolving credit facility and certain permitted exceptions. As described further in Note 6, the Deed of Trust permits Oncor to secure indebtedness (including borrowings under its revolving credit facility) with the lien of the Deed of Trust. At September 30, 2017, the available borrowing capacity of the revolving credit facility could be fully drawn.

The revolving credit facility contains customary covenants for facilities of this type, restricting, subject to certain exceptions, Oncor and its subsidiaries from, among other things: incurring additional liens; entering into mergers and consolidations; and sales of substantial assets. In addition, the revolving credit facility requires that Oncor maintain a consolidated senior debt-to-capitalization ratio of no greater than 0.65 to 1.00 and observe certain customary reporting requirements and other affirmative covenants. For purposes of the ratio, debt is calculated as indebtedness defined in the revolving credit facility (principally, the sum of long-term debt, any capital leases, short-term debt and debt due currently in accordance with GAAP). Capitalization is calculated as membership interests determined in accordance with GAAP plus indebtedness described above. At September 30, 2017, Oncor was in compliance with this covenant and with all other covenants.

18

Senior notes are secured by a first priority lien on certain transmission and distribution assets equally and ratably with all of Oncor’s other secured indebtedness. See “Deed of Trust” below for additional information. At September 30, 2017 and December 31, 2016, our long-term debt consisted of the following:

Debt-Related Activity in 2017

Debt Repayments

Repayments of long-term debt in the nine months ended September 30, 2017 consisted of $324 million aggregate principal amount of 5.00% senior secured notes due September 30, 2017 (2017 Notes) that Oncor redeemed on September 29, 2017.

Issuance of Senior Secured Notes

In September 2017, Oncor issued $325 million aggregate principal amount of 3.80% senior secured notes maturing in September 2047 (2047 Notes). Oncor used the proceeds (net of the initial purchasers’ discount, fees and expenses) of $321 million from the sale of the 2047 Notes for general corporate purposes, including repayment of borrowings under the revolving credit facility, and payment of a portion of the redemption price for the 2017 Notes. The 2047 Notes are secured by a first priority lien, and are secured equally and ratably with all of our other secured indebtedness.

Interest on the 2047 Notes is payable in cash semiannually on March 30 and September 30 of each year, beginning on March 30, 2018. Prior to March 30, 2047, Oncor may at its option at any time redeem all or part of the 2047 Notes at a price equal to 100% of their principal amount, plus accrued and unpaid interest and a make-whole premium. On and after March 30, 2047, Oncor may redeem the 2047 Notes at any time, in whole or in part, at a redemption price equal to 100% of the principal amount of such 2047 Notes, plus accrued and unpaid interest. The 2047 Notes also contain customary events of default, including failure to pay principal or interest on the Notes when due.

19

The 2047 Notes were issued in a private placement and were not registered under the Securities Act. Oncor has agreed, subject to certain exceptions, to register with the SEC notes having substantially identical terms as the 2047 Notes (except for provisions relating to the transfer restriction and payment of additional interest) as part of an offer to exchange freely tradable exchange notes for the 2047 Notes. Oncor has agreed to use commercially reasonable efforts to cause the exchange offer to be completed within 315 days after the issue date of the 2047 Notes. If a registration statement for the exchange offer is not declared effective by the SEC within 270 days after the issue date of the 2047 Notes or the exchange offer is not completed within 315 days after the issue date of the 2047 Notes (an exchange default), then the annual interest rate on the 2047 Notes will increase 50 basis points per annum until the earlier of the expiration of the exchange default or the second anniversary of the issue date of the Notes.

Term Loan Credit Agreement

On September 26, 2017, Oncor entered into a term loan credit agreement that provides for a springing-lien term loan credit facility in an aggregate principal amount of $275 million. On December 31, 2017, if (i) the obligations under the term loan credit agreement are outstanding as of such date and (ii) the obligations under our revolving credit facility (as amended, restated, supplemented, refinanced, replaced or otherwise modified) are secured as of such date, then the obligations under the term loan credit agreement will become secured indebtedness under the lien of our Deed of Trust.

The term loan credit agreement has an 18 month term maturing on March 26, 2019, and contains optional prepayment provisions as well as mandatory prepayment provisions that require prepayment in the event of certain specified debt issuances or certain specified asset dispositions.

At September 30, 2017, Oncor had outstanding borrowings of $275 million under the term loan credit agreement with an interest rate of 2.138%.

Loans under the term loan credit agreement bear interest at per annum rates equal to, at our option, (i) LIBOR plus a spread ranging from 0.80%-0.90%, depending on whether the loan has become secured, or (ii) an alternate base rate (the highest of (1) the prime rate of Wells Fargo Bank, National Association, (2) the federal funds effective rate plus 0.50%, and (3) daily one-month LIBOR plus 1.00%).

The term loan credit agreement contains customary covenants for facilities of this type, restricting, subject to certain exceptions, Oncor and its subsidiaries from, among other things, incurring additional liens, entering into mergers and consolidations, and sales of substantial assets.

In addition, the term loan credit agreement requires that Oncor maintain a consolidated senior debt to capitalization ratio of no greater than 0.65 to 1.00 and observe certain customary reporting requirements and other affirmative covenants.

The term loan credit agreement also contains customary events of default for facilities of this type the occurrence of which would allow the lenders to accelerate all outstanding loans and terminate their commitments, including certain changes in control of Oncor that are not permitted transactions under the term loan credit agreement, cross-default provisions in the event Oncor or any of its subsidiaries defaults on indebtedness in a principal amount in excess of $100 million or receives judgments for the payment of money in excess of $50 million that are not discharged within 60 days.

Deed of Trust

Secured indebtedness, including the revolving credit facility described in Note 5, is secured equally and ratably by a first priority lien on property Oncor acquired or constructed for the transmission and distribution of electricity. The property is mortgaged under the Deed of Trust. The Deed of Trust permits Oncor to secure

20

indebtedness (including borrowings under our revolving credit facility) with the lien of the Deed of Trust up to the aggregate of (i) the amount of available bond credits, and (ii) 85% of the lower of the fair value or cost of certain property additions that could be certified to the Deed of Trust collateral agent. At September 30, 2017, the amount of available bond credits was $2.495 billion and the amount of future debt Oncor could secure with property additions, subject to those property additions being certified to the Deed of Trust collateral agent, was $2.109 billion.

Fair Value of Long-Term Debt

At September 30, 2017 and December 31, 2016, the estimated fair value of Oncor’s long-term debt (including current maturities, if any) totaled $7.093 billion and $6.751 billion, respectively, and the carrying amount totaled $6.116 billion and $5.839 billion, respectively. The fair value is estimated using observable market data, representing Level 2 valuations under accounting standards related to the determination of fair value.

EFH Bankruptcy Proceedings

On the EFH Petition Date, the Debtors commenced the EFH Bankruptcy Proceedings. The Oncor Ring-Fenced Entities are not parties to the EFH Bankruptcy Proceedings. See Notes 2 and 10 for a discussion of the potential impacts on us as a result of the EFH Bankruptcy Proceedings and our related-party transactions involving members of the Texas Holdings Group, respectively.

Legal/Regulatory Proceedings

We are involved in various legal and administrative proceedings in the normal course of business, the ultimate resolution of which, in the opinion of management, should not have a material effect upon our financial position, results of operations or cash flows. See Note 3 in this report and Note 8 to Financial Statements in our 2016 Audited Financial Statements for additional information regarding our legal and regulatory proceedings.

While there are no direct restrictions on our ability to distribute our net income that are currently material, substantially all of our net income is derived from Oncor. Our board of directors and Oncor’s board of directors, which are composed of a majority of independent directors, can withhold distributions to the extent such board determines that it is necessary to retain such amounts to meet the respective company’s expected future requirements. 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 including capital leases plus unamortized gains on reacquired debt less unamortized issuance expenses, premiums and losses on reacquired debt. Equity is calculated as membership interests determined in accordance with GAAP, excluding the effects of acquisition accounting (which includes recording any initial goodwill and fair value adjustments and subsequent related impairments and amortization).

Oncor’s distributions are limited by its required regulatory capital structure to be at or below the assumed debt-to-equity ratio established periodically by the PUCT for ratemaking purposes, which was 60% debt to 40% equity as of September 30, 2017. At September 30, 2017, of its total net assets, $25 million was available for distribution to Oncor’s members as Oncor’s regulatory capitalization ratio was 59.9% debt to 40.1% equity, of which approximately 80% relates to our ownership interest. The PUCT authorized capital structure will be 57.5% debt and 42.5% equity effective November 27, 2017 contingent upon the PUCT order issued in PUCT Docket No. 46957 becoming final and taking effect (see Note 3 for more details). To obtain the additional 2.5% equity capitalization, Oncor anticipates that approximately $250 million of equity will be needed. The order in PUCT

21

Docket No. 46957 provides for the use of a regulatory liability and bill credit mechanism until the new authorized regulatory capital structure is met following the effective date for new rates to reflect Oncor’s actual capitalization prior to achieving the authorized capital structure. On October 25, 2017, Oncor’s board of directors declared a contingent cash distribution of $32 million to be paid to its members as of October 25, 2017 within one business day after an additional equity contribution is made to Oncor from members totaling approximately $250 million. In the event the additional equity contribution is not made on or before the date of the closing of the Sempra Merger Agreement, no distribution shall be payable. For more information on the Sempra Merger Agreement, see Note 2.

On October 25, 2017, our board of directors declared a contingent cash distribution to be paid to EFIH upon receipt of our portion of the contingent Oncor distribution described above, in an amount equal to the amount received from Oncor minus our expected tax liability to EFH Corp. for the quarter ended September 30, 2017 under the tax sharing agreement discussed in Note 10. No distribution is payable in the event the Oncor distribution is not received.

During the nine months ended September 30, 2017, our board of directors declared, and we paid, the following cash distributions to EFIH:

Noncontrolling Interests

At September 30, 2017, Oncor’s ownership was as follows: 80.03% held by us, 19.75% held by Texas Transmission and 0.22% held indirectly by certain current and former members of Oncor’s management team and board of directors. The book value of the noncontrolling interests exceeds its ownership percentage due the portion of Oncor’s deferred taxes not attributable to the noncontrolling interests.

Pension Plans

Oncor sponsors the Oncor Retirement Plan and also has liabilities under the Vistra Retirement Plan, both of which are qualified pension plans under Section 401(a) of the Internal Revenue Code of 1986, as amended, and are subject to the provisions of ERISA. Employees do not contribute to either plan. Oncor also has a supplemental pension plan for certain employees whose retirement benefits cannot be fully earned under the qualified retirement plans. See Note 11 to Financial Statements in our 2016 Audited Financial Statements for additional information regarding pension plans.

Oncor OPEB Plan

The Oncor OPEB Plan covers their eligible current and future retirees as well as certain eligible retirees of EFH Corp./Vistra whose employment service was assigned to both Oncor (or a predecessor regulated electric business) and a non-regulated business of EFH Corp. Vistra is solely responsible for its portion of the liability for retiree benefits related to those retirees. As Oncor is not responsible for Vistra’s portion of the Oncor OPEB Plan’s unfunded liability, that amount is not reported on our balance sheet. See Note 10 to Financial Statements in our 2016 Audited Financial Statements for additional information.
