Business And Significant Accounting Policies [Abstract]
BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES	1. BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES Description of Business References in this report to “we,” “our,” “us” and “the company” are to Oncor and/or its subsidiaries as apparent in the context. See “Glossary” for the definition of terms and abbreviations. We are a regulated electricity transmission and distribution company that provides the essential service of delivering electricity safely, reliably and economically to end-use consumers through our electrical systems, as well as providing transmission grid connections to merchant generation facilities and interconnections to other transmission grids in Texas. Our transmission and distribution rates are regulated by the PUCT and certain cities, and in certain limited instances, by the FERC. We are not a seller of electricity, nor do we purchase electricity for resale. We are a direct, majority-owned subsidiary of Oncor Holdings, which is indirectly and wholly owned by Sempra. Oncor Holdings owns 80.25 % of our outstanding membership interests and Texas Transmission owns 19.75 % of our outstanding membership interests. We are managed as an integrated business; consequently, there is only one reportable segment. Ring-Fencing Measures Since 2007, various ring-fencing measures have been taken to enhance our credit quality and the separateness between the Oncor Ring-Fenced Entities and entities with ownership interests in Oncor or Oncor Holdings. These ring-fencing measures serve to mitigate the Oncor Ring-Fenced Entities’ credit exposure to owners of Oncor and Oncor Holdings, and to reduce the risk that the assets and liabilities of the Oncor Ring-Fenced Entities would be substantively consolidated with the assets and liabilities of any direct or indirect owners of Oncor and Oncor Holdings in connection with a bankruptcy of any such entities. These measures include the November 2008 sale of 19.75 % of Oncor’s equity interests to Texas Transmission. In March 2018, Sempra indirectly acquired Oncor Holdings after obtaining various approvals, including PUCT approval through the Sempra Order, which outlines certain ring-fencing measures, governance mechanisms and restrictions that apply after the Sempra Acquisition. As a result of these ring-fencing measures, Sempra does not control Oncor, and the ring-fencing measures limit Sempra’s ability to direct the management, policies and operations of Oncor, including the deployment or disposition of Oncor’s assets, declarations of dividends, strategic planning and other important corporate issues and actions. None of the assets of the Oncor Ring-Fenced Entities are available to satisfy the debt or obligations of any Sempra entity or any other direct or indirect owner of Oncor or Oncor Holdings. The assets and liabilities of the Oncor Ring-Fenced Entities are separate and distinct from those of any Sempra entities and any other direct or indirect owner of Oncor or Oncor Holdings. We do not bear any liability for debt or contractual obligations of Sempra and its affiliates or any other direct or indirect owner of Oncor or Oncor Holdings, and vice versa. Accordingly, our operations are conducted, and our cash flows are managed, independently from Sempra and its affiliates and any other direct or indirect owner of Oncor or Oncor Holdings. Oncor is a limited liability company governed by a board of directors, not its members. The Sempra Order and our Limited Liability Company Agreement require that the board of directors of Oncor consist of thirteen members, constituted as follows:  seven Disinterested Directors, who (i) shall be independent directors in all material respects under the rules of the New York Stock Exchange in relation to Sempra or its subsidiaries and affiliated entities and any entity with a direct or indirect ownership interest in Oncor or Oncor Holdings, and (ii) shall have no material relationship with Sempra or its subsidiaries or affiliated entities or any entity with a direct or indirect ownership interest in Oncor or Oncor Holdings, currently or within the previous ten years ;  two members designated by Sempra (through Oncor Holdings);  two members designated by Texas Transmission; and  two current or former officers of Oncor (each, an Oncor Officer Director), currently Robert S. Shapard and E. Allen Nye, Jr., who are our Chairman of our board of directors and Chief Executive, respectively. Until March 9, 2028, in order for a current or former officer of Oncor to be eligible to serve as an Oncor Officer Director, the officer cannot have worked for Sempra or any of its affiliates (excluding Oncor Holdings and Oncor) or any other entity with a direct or indirect ownership interest in Oncor or Oncor Holdings in the ten-year period prior to the date on which the officer first became employed by Oncor. Oncor Holdings, at the direction of STIH, has the right to nominate and/or seek the removal of the Oncor Officer Directors, subject to approval by a majority of the Oncor board of directors. In addition, the Sempra Order provides that Oncor’s board of directors cannot be overruled by the board of directors of Sempra or any of its subsidiaries on dividend policy, the issuance of dividends or other distributions (except for contractual tax payments), debt issuance, capital expenditures, operation and maintenance expenditures, management and service fees, and appointment or removal of members of the board of directors, provided that certain actions may also require the additional approval of the Oncor Holdings board of directors. The Sempra Order also provides that any changes to the size, composition, structure or rights of the board of directors must first be approved by the PUCT. In addition, if Sempra acquires Texas Transmission’s interest in Oncor, the two board of director positions on Oncor’s board of directors that Texas Transmission is entitled to appoint will be eliminated and the size of Oncor’s board of directors will be reduced by two . Additional regulatory commitments, governance mechanisms and restrictions provided in the Sempra Order and our Limited Liability Company Agreement to ring-fence Oncor from its owners include, among others:  A majority of the Disinterested Directors of Oncor and the directors designated by Texas Transmission that are present and voting (of which at least one must be present and voting) must approve any annual or multi-year budget if the aggregate amount of capital expenditures or operating and maintenance expenditures in such budget is more than a 10 % increase or decrease from the corresponding amounts of such expenditures in the budget for the preceding fiscal year or multi-year period, as applicable;  Oncor may not pay any dividends or make any other distributions (except for contractual tax payments) if a majority of its Disinterested Directors or either of the two directors appointed by Texas Transmission determines that it is in the best interests of Oncor to retain such amounts to meet expected future requirements;  At all times, Oncor will remain in compliance with the debt-to-equity ratio established by the PUCT from time to time for ratemaking purposes, and Oncor will not pay dividends or other distributions (except for contractual tax payments), if that payment would cause its debt-to-equity ratio to exceed the debt-to-equity ratio approved by the PUCT;  If the credit rating on Oncor’s senior secured debt by any of the three major rating agencies falls below BBB (or the equivalent), Oncor will suspend dividends and other distributions (except for contractual tax payments), unless otherwise allowed by the PUCT;  Without the prior approval of the PUCT, neither Sempra nor any of its affiliates (excluding Oncor) will incur, guaranty or pledge assets in respect of any indebtedness that is dependent on the revenues of Oncor in more than a proportionate degree than the other revenues of Sempra or on the membership interests of Oncor, and there will be no debt at STH or STIH at any time following Sempra’s acquisition of Oncor Holdings;  Neither Oncor nor Oncor Holdings will lend money to, borrow money from or share credit facilities with Sempra or any of its affiliates (other than Oncor subsidiaries), or any entity with a direct or indirect ownership interest in Oncor or Oncor Holdings;  There must be maintained certain “separateness measures” that reinforce the legal and financial separation of Oncor from its owners, including a requirement that dealings between Oncor, Oncor Holdings and their subsidiaries with Sempra, any of Sempra’s other affiliates or any entity with a direct or indirect ownership interest in Oncor or Oncor Holdings, must be on an arm’s-length basis, limitations on affiliate transactions, separate recordkeeping requirements and a prohibition on Sempra or its affiliates or any entity with a direct or indirect ownership interest in Oncor or Oncor Holdings pledging Oncor assets or membership interests for any entity other than Oncor; and  Sempra will continue to hold indirectly at least 51 % of the ownership interests in Oncor and Oncor Holdings for at least five years following the Sempra Acquisition, unless otherwise specifically authorized by the PUCT. Basis of Presentation These unaudited condensed consolidated financial statements should be read in conjunction with the audited financial statements and related notes included in our 2021 Form 10-K. In the opinion of Oncor management, all adjustments (consisting of normal recurring accruals) necessary for a fair presentation of the results of operations and financial position have been made. We have evaluated all subsequent events through the date the financial statements were issued. All appropriate 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. Our consolidated financial statements have been prepared in accordance with GAAP governing rate-regulated operations. All dollar amounts in the financial statements and tables in the notes are stated in millions of U.S. dollars unless otherwise indicated. 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. No material adjustments were made to previous estimates or assumptions during the current period. Interest Rate Derivatives and Hedge Accounting We are exposed to interest rates primarily as a result of our current and expected use of financing. We may, from time to time, utilize interest rate derivative instruments typically designated as cash flow hedges, to lock in interest rates in anticipation of future financings. We may designate an interest rate derivative instrument as a cash flow hedge if it effectively converts anticipated cash flows associated with interest payments to a fixed dollar amount. In accounting for cash flow hedges, derivative assets and liabilities are recorded on the balance sheet at fair value with an offset to other comprehensive income. Amounts remain in accumulated other comprehensive income and are reclassified into net income as the interest expense on the related debt affects net income. Impairment of Long-Lived Assets and Goodwill We evaluate long-lived assets (including intangible assets with finite lives) for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. We also evaluate goodwill for impairment annually on October 1 and whenever events or changes in circumstances indicate that an impairment may exist. The determination of the existence of these and other indications of impairment involves judgments that are subjective in nature and may require the use of estimates in forecasting future results and cash flows. Cash, Cash Equivalents and Restricted Cash For purposes of reporting cash and cash equivalents, highly liquid investments with original maturities of three months or less at the date of purchase are considered to be cash equivalents. The following table provides a reconciliation of cash, cash equivalents and restricted cash reported on the Condensed Consolidated Balance Sheets to the sum of such amounts reported on the Condensed Statements of Consolidated Cash Flows: At June 30, At December 31, 2022 2021 Cash, cash equivalents and restricted cash Cash and cash equivalents $ 66 $ 11 Restricted cash, current (a) 17 13 Restricted cash, noncurrent (a) 60 30 Total cash, cash equivalents and restricted cash on the Condensed Statements of Consolidated Cash Flows $ 143 $ 54 ____________ (a) Restricted cash represents amounts deposited with Oncor by our customers that are subject to return in accordance with PUCT rules, ERCOT requirements or our tariffs relating to generation interconnection and construction and/or extension of electric delivery system facilities. We maintain these amounts in a separate escrow account. Contingencies Our financial results may be affected by judgments and estimates related to contingencies. For loss contingencies, we accrue the loss if an event has occurred on or before the balance sheet date, and:  information available through the date we file our financial statements indicates it is probable that a loss has been incurred, given the likelihood of uncertain future events; and  the amount of the loss can be reasonably estimated. We do not accrue contingencies that might result in gains. We continuously assess contingencies for litigation claims, environmental remediation and other events. See Note 6 for a discussion of contingencies. Effects of Reference Rate Reform on Financial Reporting Our Credit Facility uses LIBOR as a benchmark for establishing interest rates but incorporates a transition mechanism for the phase-out of LIBOR. In the event we modify our Credit Facility related to the phase-out of LIBOR, we will evaluate the optional expedients and exceptions under ASU No. 2020-04. The standard allows entities to account for contract modifications as an event that does not require reassessment or remeasurement (i.e., as a continuation of the existing contract). ASU No. 2020-04 became effective on March 12, 2020 and will remain effective until December 31, 2022.

(b) Recovery/refund is specifically authorized by statute or by the PUCT, subject to reasonableness review. (c) Represents unfunded liabilities recorded in accordance with pension and OPEB accounting standards. 2022 Base Rate Review (PUCT Docket No. 53601) On May 13, 2022, we filed a request for a base rate review with the PUCT and the 209 cities in our service territory that have retained original jurisdiction over rates. The rate review test year is based on calendar year 2021 results with certain adjustments. The rate review includes a request for an annual revenue requirement increase over current adjusted rates of 4.5 % and, if approved as requested, would result in an aggregate annual revenue requirement increase of approximately $ 251 million. The rate review also requests a revised regulatory capital structure ratio of 55 % debt to 45 % equity and an authorized return on equity of 10.30 %. Our current authorized regulatory capital structure ratio is 57.5 % debt to 42.5 % equity and our current authorized return on equity is 9.8 %. In June, a procedural schedule was agreed to by the parties to the proceeding, which would result in a hearing on the merits being held from September 26, 2022 to October 5, 2022, if a settlement is not reached among the parties. We also agreed to extend the requested effective date of the rate increase such that the jurisdictional deadline for the PUCT to act on our rate review request has been extended to December 29, 2022. PUCT Project No. 50664, Issues Related to the State of Disaster for the Coronavirus Disease 2019 In March 2020, the PUCT issued an order in PUCT Project No. 50664, Issues Related to the State of Disaster for the Coronavirus Disease 2019 , authorizing transmission and distribution utilities to use a regulatory asset accounting mechanism and a subsequent process to seek future recovery of expenses resulting from the effects of the COVID-19 pandemic. Since then, we have been recording incremental costs incurred by Oncor resulting from the effects of the COVID-19 pandemic, including costs relating to the implementation of our pandemic r eadiness plan, as a regulatory asset. At June 30, 2022, the balance of this regulatory asset was $ 36 million.

Revenues [Abstract]
REVENUES	3. REVENUES General Our revenue is billed monthly 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 to customers including a reasonable rate of return on invested capital. As the volumes delivered can be directly measured, our revenues are recognized when the underlying service has been provided in an amount prescribed by the related tariff. We recognize revenue in the amount that we have the right to invoice. Substantially all of our revenues are from contracts with customers except for alternative revenue program revenues discussed below. Reconcilable Tariffs The PUCT has designated certain tariffs (primarily TCRF and EECRF) 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. Alternative Revenue Program The PUCT has implemented an incentive program allowing us to earn energy efficiency program performance bonuses by exceeding PUCT-approved energy efficiency program targets. This incentive program and the related performance bonus revenues are considered an “alternative revenue program” under GAAP. Annual performance bonuses are recognized as revenue when approved by the PUCT, typically in the third or fourth quarter each year. Disaggregation of Revenues The following table reflects electric delivery revenues disaggregated by tariff: Three Months Ended June 30, Six Months Ended June 30, 2022 2021 2022 2021 Operating revenues Revenues contributing to earnings: Distribution base revenues $ 600 $ 517 $ 1,178 $ 1,058 Transmission base revenues (TCOS revenues): Billed to third-party wholesale customers 237 222 470 429 Billed to REPs serving Oncor distribution customers, through TCRF 132 120 262 234 Total transmission base revenues 369 342 732 663 Other miscellaneous revenues 22 19 40 36 Total revenues contributing to earnings 991 878 1,950 1,757 Revenues collected for pass-through expenses: TCRF – third-party wholesale transmission service 290 260 571 509 EECRF 12 9 21 20 Total revenues collected for pass-through expenses 302 269 592 529 Total operating revenues $ 1,293 $ 1,147 $ 2,542 $ 2,286 Customers Our distribution business customers consist of REPs (approximately 100 at June 30, 2022) and certain electric cooperatives in our certificated service area. The consumers of the electricity we deliver are free to choose their electricity supplier from REPs who compete for their business. Our transmission base revenues are collected from load serving entities benefiting from our transmission system. Our transmission business customers consist of other distribution companies, municipalities and electric cooperatives. REP subsidiaries of our two largest customers collectively represented 23 % and 21 % of our total operating revenues for the three months ended June 30, 2022 and 24 % and 23 % of our total operating revenues for the six months ended June 30, 2022. No other customer represented more than 10% of our total operating revenues for the three and six months ended June 30, 2022. Variability Our revenues and cash flows are subject to seasonality, timing of customer billings, weather conditions and other electricity usage drivers, with revenues being highest in the summer. Payment of customer billings is due 35 days after invoicing. Under a PUCT rule relating to the Certification of Retail Electric Providers, write-offs of uncollectible amounts owed by REPs are recoverable as a regulatory asset. Pass-through Expenses Revenue equal to expenses that are allowed to be passed-through to customers (primarily third-party wholesale transmission service and energy efficiency program costs) are recognized at the time the expense is recognized. Franchise taxes are assessed by local governmental bodies, based on kWh delivered, and are not a “pass-through” item. The rates we charge customers are intended to recover the franchise taxes, but we are not acting as an agent to collect the taxes from customers; therefore, franchise taxes are reported as a principal component of “taxes other than amounts related to income taxes” instead of a reduction to “revenues” in the income statement.

(b) The interest rate on outstanding letters of credit was 1.20 % at December 31, 2021, based on our credit ratings. Credit Facility In November 2021, we entered into a $ 2.0 billion unsecured revolving Credit Facility that includes sustainability-linked pricing metrics related to specific environmental and employee health and safety sustainability objectives. The Credit Facility may be used for working capital and other general corporate purposes, issuances of letters of credit and to support our CP Program. The Credit Facility has a maturity date of November 9, 2026. We also have the option of requesting up to two 1 -year extensions and an option to request an increase in our borrowing capacity of up to $ 400 million in $ 100 million minimum increments, provided certain conditions set forth in the Credit Facility are met, including lender approvals. CP Program We maintain the CP Program under which we may issue unsecured CP Notes on a private placement basis up to a maximum aggregate face or principal amount outstanding at any time of $ 2.0 billion. The proceeds of CP Notes issued under the CP Program are used for working capital and other general corporate purposes. The CP Program obtains liquidity support from our Credit Facility discussed above. We may utilize either the CP Program or the Credit Facility, at our option, to meet our funding needs.

LONG-TERM DEBT	5. LONG-TERM DEBT Our long-term debt includes fixed rate secured and variable rate unsecured debt. Our secured debt is secured equally and ratably by a first priority lien on certain transmission and distribution assets. See “Deed of Trust” below for additional information.

The January 2022 Term Loan Credit Agreement matures on April 29, 2023. We borrowed $ 400 million on January 28, 2022 , $ 600 million on February 28, 2022 (February 2022 borrowing), $ 185 million on March 28, 2022, and $ 115 million on April 28, 2022 (April 2022 borrowing) under the January 2022 Term Loan Credit Agreement. Following the April 2022 borrowing, no additional amounts remain available for borrowing under the January 2022 Term Loan Credit Agreement. The proceeds from each borrowing were used for general corporate purposes, including to repay outstanding CP Notes and, in the case of the February 2022 borrowing, to redeem in full the $ 400 million aggregate principal amount outstanding of our 4.10 % senior secured notes due June 1, 2022 (2022 Notes), plus accrued and unpaid interest on the 2022 Notes. On May 20, 2022, we repaid $ 650 million of the principal amount outstanding under the January 2022 Term Loan Credit Agreement. See “2032 Notes and 2052 Notes Issuances” below for more information. As a result of the repayment, the aggregate principal amount outstanding under the January 2022 Term Loan Credit Agreement at June 30, 2022 totaled $ 650 million. Loans under the January 2022 Term Loan Credit Agreement bear interest , at our option, at either (i) an adjusted term SOFR (calculated based on one-month term SOFR as of a specified date, plus an adjustment of 0.10 % (SOFR Adjustment)) plus a spread of 0.575 %, (ii) an adjusted daily simple SOFR (calculated based on daily simple SOFR as of a specified date, plus the SOFR Adjustment) plus a spread of 0.575 %, or (iii) for any day, at a rate equal to the greatest of: (1) the prime rate publicly announced by the administrative agent on such date, (2) the federal funds effective rate on such date plus 0.50 %, and (3) daily simple SOFR on such date, plus 1.0 %. 2022 Notes Redemption On March 1, 2022, we redeemed in full the $400 million aggregate principal amount outstanding of our 2022 Notes, which were to mature on June 1, 2022. The redemption price was equal to 100 % of the principal amount of the 2022 Notes, plus accrued interest to, but not including, the redemption date of March 1, 2022. Following the redemption of the 2022 Notes, none of the 2022 Notes remain outstanding. 2032 Notes and 2052 Notes Issuances On May 20, 2022, we issued $ 400 million aggregate principal amount of 4.15 % senior secured notes due June 1, 2032 (2032 Notes) and $ 400 million aggregate principal amount of 4.60 % senior secured notes due June 1, 2052 (2052 Notes). We intend to allocate/disburse the proceeds from the sale of the 2032 Notes ( net of the discounts and fees to the initial purchasers and the estimated pro rata expenses related to the offering of the 2032 Notes ) of approximately $ 395 million, or an amount equal to the net proceeds from the sale of the 2032 Notes, to finance and/or refinance, in whole or in part, investments in or expenditures on one or more new and/or existing eligible green projects in accordance with our sustainable financing framework. Eligible green projects include transmission and distribution projects connecting renewable energy sources to the ERCOT grid, customer energy efficiency programs, and deployment of automated metering infrastructure and smart grid technology. Prior to the allocation/disbursement of the full amount of the net proceeds from the sale of the 2032 Notes, we temporarily applied the entire amount of such net proceeds to repay a portion of the principal amount outstanding under the January 2022 Term Loan Credit Agreement. We used the proceeds from the sale of the 2052 Notes (net of the discounts and fees to the initial purchasers and the estimated pro rata expenses related to the offering of the 2052 Notes) of approximately $ 392 million for general corporate purposes, including to repay $ 255 million of the principal amount outstanding under the January 2022 Term Loan Credit Agreement. The 2032 Notes and 2052 Notes were issued pursuant to the provisions of an Indenture, dated as of August 1, 2002, between Oncor and The Bank of New York Mellon Trust Company, N.A. (as successor to The Bank of New York Mellon, formerly The Bank of New York), as trustee, as amended and supplemented. The 2032 Notes bear interest at a rate of 4.15% per annum and mature on June 1, 2032. The 2052 Notes bear interest at a rate of 4.60% per annum and mature on June 1, 2052. Interest on the 2032 Notes and the 2052 Notes is payable in cash semi-annually in arrears on June 1 and December 1 of each year, beginning on December 1, 2022. Prior to March 1, 2032, in the case of the 2032 Notes and December 1, 2051 in the case of the 2052 Notes, we may redeem such notes at any time, in whole or in part, at a price equal to 100 % of their principal amount, plus accrued and unpaid interest and a “make-whole” premium. On and after March 1, 2032 in the case of the 2032 Notes and December 1, 2051 in the case of the 2052 Notes, we may redeem the notes at any time, in whole or in part, at a redemption price equal to 100 % of the principal amount of such notes, plus accrued and unpaid interest. The 2032 Notes and 2052 Notes were issued in a private placement and were not registered under the Securities Act. In connection with the completion of the sale of the 2032 Notes and 2052 Notes, we entered into a Registration Rights Agreement with the representatives of the initial purchasers of such notes (the Registration Rights Agreement). Under the Registration Rights Agreement, we agreed, subject to certain exceptions, to file a registration statement with the SEC with respect to a registered offer to exchange the 2032 Notes and the 2052 Notes for publicly registered notes (the Exchange Offer Registration Statement), or under certain circumstances, a shelf registration statement (the Shelf Registration Statement). We have agreed to use commercially reasonable efforts to cause the Exchange Offer Registration Statement to be declared effective under the Securities Act on or prior to June 1, 2023 and to consummate the exchange offer on or prior to July 15, 2023. Oncor agreed to use commercially reasonable efforts to cause any Shelf Registration Statement to become or be declared effective within the later of 180 days after such Shelf Registration Statement filing obligation arises and June 1, 2023. If we do not comply with certain of our obligations under the Registration Rights Agreement, the affected notes will bear additional interest on the principal amount of such affected notes at a rate of 0.50 % per annum over the interest rate otherwise provided for under such notes for the period during which the registration default continues, but not later than the second anniversary of the issue date of such notes. Long-Term Debt-Related Activity Subsequent to June 30, 2022 July 2022 Term Loan Credit Agreement On July 6, 2022, we entered into an unsecured term loan credit agreement with a commitment equal to an aggregate principal amount of $ 650 million (July 2022 Term Loan Credit Agreement) with a maturity date that is 366 days after the date on which the funding availability period ends. The July 2022 Term Loan Credit Agreement provides that we may borrow up to the full amount available under the July 2022 Term Loan Credit Agreement in up to three borrowings, which may be made, at our option, at any time on or before August 31, 2022. We intend to use the proceeds from any borrowings under the July 2022 Term Loan Credit Agreement for general corporate purposes. At the time of this quarterly report on Form 10-Q, no borrowings have been made under the July 2022 Term Loan Credit Agreement. Loans under the July 2022 Term Loan Credit Agreement bear interest , at our option, at either (i) an adjusted term SOFR (calculated based on one-month term SOFR as of a specified date, plus the SOFR Adjustment) plus a spread of 0.60 %, (ii) an adjusted daily simple SOFR (calculated based on daily simple SOFR as of a specified date, plus the SOFR Adjustment) plus a spread of 0.60 %, or (iii) for any day, at a rate equal to the greatest of: (1) the prime rate publicly announced by the administrative agent on such date, (2) the federal funds effective rate on such date plus 0.50 %, and (3) daily simple SOFR on such date, plus 1.0 %. Deed of Trust Our secured debt is secured equally and ratably by a first priority lien on all property acquired or constructed by Oncor for use in its electricity transmission and distribution business, subject to certain exceptions. The property is mortgaged under the Deed of Trust. The Deed of Trust permits us to secure indebtedness 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 June 30, 2022, the amount of available bond credits was $ 2.111 billion and the amount of future debt we could secure with property additions, subject to those property additions being certified to the Deed of Trust collateral agent, was $ 4.692 billion. Borrowings under the CP Program, the Credit Facility and the term loans are not secured. Fair Value of Long-Term Debt At June 30, 2022 and December 31, 2021, the estimated fair value of our long-term debt (including current maturities) totaled $ 10.856 billion and $ 11.758 billion, respectively, and the carrying amount totaled $ 11.072 billion and $ 10.032 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.

Commitments And Contingencies [Abstract]
COMMITMENTS AND CONTINGENCIES	6. COMMITMENTS AND CONTINGENCIES Legal/Regulatory Proceedings In May 2022, we filed a base rate review with the PUCT and the cities in our service territory that have retained original jurisdiction over rates. See Note 2 above for additional information regarding that rate review. We are also involved in other 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 2 above and Note 7 to Financial Statements in our 2021 Form 10-K for additional information regarding our regulatory and legal proceedings, respectively. Leases As lessee, our leased assets primarily consist of our vehicle fleet and real estate leased for company offices and service centers. Our leases are accounted for as operating leases for GAAP purposes. At June 30, 2022, we had $ 5 million in GAAP operating leases that are treated as capital leases solely for rate-making purposes. We generally recognize operating lease costs on a straight-line basis over the lease term in operating expenses. We are not a lessor to any material lease contracts. See Note 7 to Financial Statements in our 2021 Form 10-K for additional information on leases. Sales and Use Tax Audits We are subject to sales and use tax audits in the normal course of business. Currently, the Texas State Comptroller’s office is conducting sales and use tax audits for audit periods 2010 through June 2013, July 2013 through 2017, and 2018 through 2021. No audit reports have been issued for these audits. While the outcome is uncertain, based on our analysis, we do not expect the ultimate resolution of these audits will have a material adverse effect on our financial position, results of operations, or cash flows.

Membership Interests [Abstract]
MEMBERSHIP INTERESTS	7. MEMBERSHIP INTERESTS Contributions We received $ 106 million in cash capital contributions from our members on July 26, 2022. In the six months ended June 30, 2022, we received the following cash capital contributions from our members: Receipt Date Amount February 17, 2022 $ 106 April 26, 2022 $ 106 Distributions The Sempra Order and our Limited Liability Company Agreement set forth various restrictions on distributions to our members. Among those restrictions is the commitment that we will make no distributions (other than contractual tax payments) to our members that would cause us to exceed the PUCT’s authorized debt-to-equity ratio. Our current authorized regulatory capital structure is 57.5 % debt to 42.5 % equity. The distribution restrictions also include the ability of a majority of our Disinterested Directors, or either of the two member directors designated by Texas Transmission, to limit distributions to the extent each determines it is necessary to meet expected future requirements of Oncor (including continuing compliance with the PUCT debt-to-equity ratio commitment). At June 30, 2022, our regulatory capitalization was 54.4 % debt to 45.6 % equity and as a result we had $ 1.115 billion available to distribute to our members. 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 any finance 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 accumulated other comprehensive loss and the effects of acquisition accounting from a 2007 transaction. On July 27, 2022, our board of directors declared a cash distribution of $ 106 million, which was paid to our members on July 28, 2022. In the six months ended June 30, 2022, our board of directors declared, and we paid, the following cash distributions to our members: Declaration Date Payment Date Amount February 18, 2022 February 18, 2022 $ 106 April 27, 2022 April 28, 2022 $ 106 Membership Interests The following tables present the changes to membership interests during the three and six months ended June 30, 2022 and 2021, net of tax: Capital Accounts Accumulated Other Comprehensive Income (Loss) Total Membership Interests Balance at March 31, 2022 $ 12,913 $ ( 129 ) $ 12,784 Net income 229 - 229 Capital contributions 106 - 106 Distributions ( 106 ) - ( 106 ) Defined benefit pension plans - 1 1 Balance at June 30, 2022 $ 13,142 $ ( 128 ) $ 13,014 Balance at March 31, 2021 $ 12,218 $ ( 149 ) $ 12,069 Net income 169 - 169 Capital contributions 62 - 62 Distributions ( 96 ) - ( 96 ) Defined benefit pension plans - 3 3 Balance at June 30, 2021 $ 12,353 $ ( 146 ) $ 12,207 Capital Accounts Accumulated Other Comprehensive Income (Loss) Total Membership Interests Balance at December 31, 2021 $ 12,719 $ ( 131 ) $ 12,588 Net income 423 - 423 Capital contributions 212 - 212 Distributions ( 212 ) - ( 212 ) Net effects of cash flow hedges - 1 1 Defined benefit pension plans - 2 2 Balance at June 30, 2022 $ 13,142 $ ( 128 ) $ 13,014 Balance at December 31, 2020 $ 12,083 $ ( 151 ) $ 11,932 Net income 337 - 337 Capital contributions 125 - 125 Distributions ( 192 ) - ( 192 ) Net effects of cash flow hedges - 1 1 Defined benefit pension plans - 4 4 Balance at June 30, 2021 $ 12,353 $ ( 146 ) $ 12,207 Accumulated Other Comprehensive Income (Loss) (AOCI) The following table presents the changes to AOCI for the six months ended June 30, 2022 and 2021, net of tax: Cash Flow Hedges – Interest Rate Swaps Defined Benefit Pension and OPEB Plans Total Accumulated Other Comprehensive Income (Loss) Balance at December 31, 2021 $ ( 36 ) $ ( 95 ) $ ( 131 ) Defined benefit pension plans - 2 2 Cash flow hedge amounts reclassified from AOCI and reported in interest expense and related charges (net of tax expense of $ 0 ) 1 - 1 Balance at June 30, 2022 $ ( 35 ) $ ( 93 ) $ ( 128 ) Balance at December 31, 2020 $ ( 39 ) $ ( 112 ) $ ( 151 ) Defined benefit pension plans - 4 4 Cash flow hedge amounts reclassified from AOCI and reported in interest expense and related charges (net of tax expense of $ 0 ) 1 - 1 Balance at June 30, 2021 $ ( 38 ) $ ( 108 ) $ ( 146 )

Pension And OPEB Plans [Abstract]
PENSION AND OPEB PLANS	8. PENSION AND OPEB PLANS Pension Plans We sponsor the Oncor Retirement Plan and also have liabilities related to 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. We also have a supplemental retirement plan for certain employees whose retirement benefits cannot be fully earned under the qualified retirement plans. See Note 9 to Financial Statements in our 2021 Form 10-K for additional information regarding pension plans. OPEB Plans We currently sponsor two OPEB plans. One plan covers our eligible current and future retirees whose services are 100 % attributed to the regulated business. The second plan covers retirees and eligible current and future retirees whose employment services were assigned to both Oncor (or a predecessor regulated utility business) and the non-regulated business of certain formerly affiliated companies, including Vistra. Vistra is solely responsible for its portion of the liability for retiree benefits related to those retirees. See Note 9 to Financial Statements in our 2021 Form 10-K for additional information. Pension and OPEB Costs Our net costs related to pension plans and the OPEB Plans for the three and six months ended June 30, 2022 and 2021, were comprised of the following: Three Months Ended June 30, Six Months Ended June 30, 2022 2021 2022 2021 Components of net allocated pension costs: Service cost $ 8 $ 8 $ 16 $ 17 Interest cost (a) 23 21 45 42 Expected return on assets (a) ( 27 ) ( 25 ) ( 53 ) ( 50 ) Amortization of net loss (a) 8 13 16 26 Net pension costs 12 17 24 35 Net adjustments (b) ( 1 ) ( 6 ) ( 2 ) ( 12 ) Net pension costs recognized as operation and maintenance expense or other deductions $ 11 $ 11 $ 22 $ 23 Components of net OPEB costs: Service cost $ 1 $ 1 $ 2 $ 2 Interest cost (a) 6 7 12 13 Expected return on assets (a) ( 2 ) ( 2 ) ( 4 ) ( 3 ) Amortization of prior service cost - ( 4 ) - ( 8 ) Amortization of net loss (a) - 5 - 9 Net OPEB costs 5 7 10 13 Net adjustments (b) 3 1 5 2 Net OPEB costs recognized as operation and maintenance expense or other deductions $ 8 $ 8 $ 15 $ 15 ____________ (a) The components of net costs other than service cost component are recorded in “Other deductions and (income) – net” in Condensed Statements of Consolidated Income. (b) Net adjustments include amounts principally deferred as property, regulatory asset or regulatory liability. The discount rates reflected in net pension and OPEB costs in 2022 are 2.91 %, 2.94 % and 2.47 % for the Oncor Retirement Plan, the Vistra Retirement Plan and the OPEB Plans, respectively. The expected return on pension and OPEB plan assets reflected in the 2022 cost amounts are 4.87 %, 4.66 % and 5.61 % for the Oncor Retirement Plan, the Vistra Retirement Plan and the OPEB Plans, respectively. Pension Plans and OPEB Plans Cash Contributions We made cash contributions to the pension plans and OPEB Plans of $ 2 million and $ 18 million, respectively, during the six months ended June 30, 2022. We expect to make additional cash contributions to the pension plans and OPEB Plans of $ 3 million and $ 17 million, respectively, during the remainder of 2022. Our pension plans and OPEB Plans funding is expected to total approximately $ 273 million and $ 141 million, respectively, in the five-year period from 2022 to 2026 based on the latest actuarial projections.

Related-Party Transactions [Abstract]
RELATED-PARTY TRANSACTIONS	9. RELATED-PARTY TRANSACTIONS The following represent our significant related-party transactions.  We are not a member of another entity’s consolidated tax group, but our owners’ federal income tax returns include their portion of our results. Under the terms of a tax sharing agreement among us, Oncor Holdings, Texas Transmission and STH, we are generally obligated to make payments to our owners, pro rata in accordance with their respective membership interests, in an aggregate amount that is substantially equal to the amount of federal income taxes that we would have been required to pay if we were filing our own corporate income tax return. STH will file a combined Texas margin tax return that includes our results and our share of Texas margin tax payments, which are accounted for as income taxes and calculated as if we were filing our own return. See discussion in Note 1 to Financial Statements in our 2021 Form 10-K under “Provision in Lieu of Income Taxes.” Under the “in lieu of” tax concept, all in lieu of tax assets and tax liabilities represent amounts that will eventually be settled with our members. In the event such amounts are not paid under the tax sharing agreement, it is probable that these regulatory amounts will continue to be included in Oncor’s rate setting processes. Amounts payable to (receivable from) members related to income taxes under the tax sharing agreement and reported on our balance sheets consisted of the following: At June 30, 2022 At December 31, 2021 STH Texas Transmission Total STH Texas Transmission Total Federal income taxes payable (receivable) $ ( 2 ) $ ( 1 ) $ ( 3 ) $ ( 5 ) $ ( 1 ) $ ( 6 ) Texas margin tax payable 15 - 15 24 - 24 Net payable (receivable) $ 13 $ ( 1 ) $ 12 $ 19 $ ( 1 ) $ 18 Cash payments made to members related to income taxes for the six months ended June 30, 2022 and 2021 consisted of the following: Six Months Ended June 30, 2022 Six Months Ended June 30, 2021 STH Texas Transmission Total STH Texas Transmission Total Federal income taxes $ 41 $ 10 $ 51 $ 26 $ 6 $ 32 Texas margin tax 22 - 22 21 - 21 Total payments $ 63 $ 10 $ 73 $ 47 $ 6 $ 53 See Note 7 for information regarding cash capital contributions from and distributions to members.  Sempra owns an indirect 50 percent interest in the parent of Sharyland.

Business And Significant Accounting Policies [Abstract]
Description Of Business	Description of Business References in this report to “we,” “our,” “us” and “the company” are to Oncor and/or its subsidiaries as apparent in the context. See “Glossary” for the definition of terms and abbreviations. We are a regulated electricity transmission and distribution company that provides the essential service of delivering electricity safely, reliably and economically to end-use consumers through our electrical systems, as well as providing transmission grid connections to merchant generation facilities and interconnections to other transmission grids in Texas. Our transmission and distribution rates are regulated by the PUCT and certain cities, and in certain limited instances, by the FERC. We are not a seller of electricity, nor do we purchase electricity for resale. We are a direct, majority-owned subsidiary of Oncor Holdings, which is indirectly and wholly owned by Sempra. Oncor Holdings owns 80.25 % of our outstanding membership interests and Texas Transmission owns 19.75 % of our outstanding membership interests. We are managed as an integrated business; consequently, there is only one reportable segment.
Ring-Fencing Measures	Ring-Fencing Measures Since 2007, various ring-fencing measures have been taken to enhance our credit quality and the separateness between the Oncor Ring-Fenced Entities and entities with ownership interests in Oncor or Oncor Holdings. These ring-fencing measures serve to mitigate the Oncor Ring-Fenced Entities’ credit exposure to owners of Oncor and Oncor Holdings, and to reduce the risk that the assets and liabilities of the Oncor Ring-Fenced Entities would be substantively consolidated with the assets and liabilities of any direct or indirect owners of Oncor and Oncor Holdings in connection with a bankruptcy of any such entities. These measures include the November 2008 sale of 19.75 % of Oncor’s equity interests to Texas Transmission. In March 2018, Sempra indirectly acquired Oncor Holdings after obtaining various approvals, including PUCT approval through the Sempra Order, which outlines certain ring-fencing measures, governance mechanisms and restrictions that apply after the Sempra Acquisition. As a result of these ring-fencing measures, Sempra does not control Oncor, and the ring-fencing measures limit Sempra’s ability to direct the management, policies and operations of Oncor, including the deployment or disposition of Oncor’s assets, declarations of dividends, strategic planning and other important corporate issues and actions. None of the assets of the Oncor Ring-Fenced Entities are available to satisfy the debt or obligations of any Sempra entity or any other direct or indirect owner of Oncor or Oncor Holdings. The assets and liabilities of the Oncor Ring-Fenced Entities are separate and distinct from those of any Sempra entities and any other direct or indirect owner of Oncor or Oncor Holdings. We do not bear any liability for debt or contractual obligations of Sempra and its affiliates or any other direct or indirect owner of Oncor or Oncor Holdings, and vice versa. Accordingly, our operations are conducted, and our cash flows are managed, independently from Sempra and its affiliates and any other direct or indirect owner of Oncor or Oncor Holdings. Oncor is a limited liability company governed by a board of directors, not its members. The Sempra Order and our Limited Liability Company Agreement require that the board of directors of Oncor consist of thirteen members, constituted as follows:  seven Disinterested Directors, who (i) shall be independent directors in all material respects under the rules of the New York Stock Exchange in relation to Sempra or its subsidiaries and affiliated entities and any entity with a direct or indirect ownership interest in Oncor or Oncor Holdings, and (ii) shall have no material relationship with Sempra or its subsidiaries or affiliated entities or any entity with a direct or indirect ownership interest in Oncor or Oncor Holdings, currently or within the previous ten years ;  two members designated by Sempra (through Oncor Holdings);  two members designated by Texas Transmission; and  two current or former officers of Oncor (each, an Oncor Officer Director), currently Robert S. Shapard and E. Allen Nye, Jr., who are our Chairman of our board of directors and Chief Executive, respectively. Until March 9, 2028, in order for a current or former officer of Oncor to be eligible to serve as an Oncor Officer Director, the officer cannot have worked for Sempra or any of its affiliates (excluding Oncor Holdings and Oncor) or any other entity with a direct or indirect ownership interest in Oncor or Oncor Holdings in the ten-year period prior to the date on which the officer first became employed by Oncor. Oncor Holdings, at the direction of STIH, has the right to nominate and/or seek the removal of the Oncor Officer Directors, subject to approval by a majority of the Oncor board of directors. In addition, the Sempra Order provides that Oncor’s board of directors cannot be overruled by the board of directors of Sempra or any of its subsidiaries on dividend policy, the issuance of dividends or other distributions (except for contractual tax payments), debt issuance, capital expenditures, operation and maintenance expenditures, management and service fees, and appointment or removal of members of the board of directors, provided that certain actions may also require the additional approval of the Oncor Holdings board of directors. The Sempra Order also provides that any changes to the size, composition, structure or rights of the board of directors must first be approved by the PUCT. In addition, if Sempra acquires Texas Transmission’s interest in Oncor, the two board of director positions on Oncor’s board of directors that Texas Transmission is entitled to appoint will be eliminated and the size of Oncor’s board of directors will be reduced by two . Additional regulatory commitments, governance mechanisms and restrictions provided in the Sempra Order and our Limited Liability Company Agreement to ring-fence Oncor from its owners include, among others:  A majority of the Disinterested Directors of Oncor and the directors designated by Texas Transmission that are present and voting (of which at least one must be present and voting) must approve any annual or multi-year budget if the aggregate amount of capital expenditures or operating and maintenance expenditures in such budget is more than a 10 % increase or decrease from the corresponding amounts of such expenditures in the budget for the preceding fiscal year or multi-year period, as applicable;  Oncor may not pay any dividends or make any other distributions (except for contractual tax payments) if a majority of its Disinterested Directors or either of the two directors appointed by Texas Transmission determines that it is in the best interests of Oncor to retain such amounts to meet expected future requirements;  At all times, Oncor will remain in compliance with the debt-to-equity ratio established by the PUCT from time to time for ratemaking purposes, and Oncor will not pay dividends or other distributions (except for contractual tax payments), if that payment would cause its debt-to-equity ratio to exceed the debt-to-equity ratio approved by the PUCT;  If the credit rating on Oncor’s senior secured debt by any of the three major rating agencies falls below BBB (or the equivalent), Oncor will suspend dividends and other distributions (except for contractual tax payments), unless otherwise allowed by the PUCT;  Without the prior approval of the PUCT, neither Sempra nor any of its affiliates (excluding Oncor) will incur, guaranty or pledge assets in respect of any indebtedness that is dependent on the revenues of Oncor in more than a proportionate degree than the other revenues of Sempra or on the membership interests of Oncor, and there will be no debt at STH or STIH at any time following Sempra’s acquisition of Oncor Holdings;  Neither Oncor nor Oncor Holdings will lend money to, borrow money from or share credit facilities with Sempra or any of its affiliates (other than Oncor subsidiaries), or any entity with a direct or indirect ownership interest in Oncor or Oncor Holdings;  There must be maintained certain “separateness measures” that reinforce the legal and financial separation of Oncor from its owners, including a requirement that dealings between Oncor, Oncor Holdings and their subsidiaries with Sempra, any of Sempra’s other affiliates or any entity with a direct or indirect ownership interest in Oncor or Oncor Holdings, must be on an arm’s-length basis, limitations on affiliate transactions, separate recordkeeping requirements and a prohibition on Sempra or its affiliates or any entity with a direct or indirect ownership interest in Oncor or Oncor Holdings pledging Oncor assets or membership interests for any entity other than Oncor; and  Sempra will continue to hold indirectly at least 51 % of the ownership interests in Oncor and Oncor Holdings for at least five years following the Sempra Acquisition, unless otherwise specifically authorized by the PUCT.
Basis Of Presentation	Basis of Presentation These unaudited condensed consolidated financial statements should be read in conjunction with the audited financial statements and related notes included in our 2021 Form 10-K. In the opinion of Oncor management, all adjustments (consisting of normal recurring accruals) necessary for a fair presentation of the results of operations and financial position have been made. We have evaluated all subsequent events through the date the financial statements were issued. All appropriate 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. Our consolidated financial statements have been prepared in accordance with GAAP governing rate-regulated operations. All dollar amounts in the financial statements and tables in the notes are stated in millions of U.S. dollars unless otherwise indicated.
Use Of Estimates	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. No material adjustments were made to previous estimates or assumptions during the current period.
Interest Rate Derivatives And Hedge Accounting	Interest Rate Derivatives and Hedge Accounting We are exposed to interest rates primarily as a result of our current and expected use of financing. We may, from time to time, utilize interest rate derivative instruments typically designated as cash flow hedges, to lock in interest rates in anticipation of future financings. We may designate an interest rate derivative instrument as a cash flow hedge if it effectively converts anticipated cash flows associated with interest payments to a fixed dollar amount. In accounting for cash flow hedges, derivative assets and liabilities are recorded on the balance sheet at fair value with an offset to other comprehensive income. Amounts remain in accumulated other comprehensive income and are reclassified into net income as the interest expense on the related debt affects net income.
Impairment Of Long-Lived Assets And Goodwill	Impairment of Long-Lived Assets and Goodwill We evaluate long-lived assets (including intangible assets with finite lives) for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. We also evaluate goodwill for impairment annually on October 1 and whenever events or changes in circumstances indicate that an impairment may exist. The determination of the existence of these and other indications of impairment involves judgments that are subjective in nature and may require the use of estimates in forecasting future results and cash flows.
Cash, Cash Equivalents and Restricted Cash	Cash, Cash Equivalents and Restricted Cash For purposes of reporting cash and cash equivalents, highly liquid investments with original maturities of three months or less at the date of purchase are considered to be cash equivalents. The following table provides a reconciliation of cash, cash equivalents and restricted cash reported on the Condensed Consolidated Balance Sheets to the sum of such amounts reported on the Condensed Statements of Consolidated Cash Flows: At June 30, At December 31, 2022 2021 Cash, cash equivalents and restricted cash Cash and cash equivalents $ 66 $ 11 Restricted cash, current (a) 17 13 Restricted cash, noncurrent (a) 60 30 Total cash, cash equivalents and restricted cash on the Condensed Statements of Consolidated Cash Flows $ 143 $ 54 ____________ (a) Restricted cash represents amounts deposited with Oncor by our customers that are subject to return in accordance with PUCT rules, ERCOT requirements or our tariffs relating to generation interconnection and construction and/or extension of electric delivery system facilities. We maintain these amounts in a separate escrow account.
Contingencies	Contingencies Our financial results may be affected by judgments and estimates related to contingencies. For loss contingencies, we accrue the loss if an event has occurred on or before the balance sheet date, and:  information available through the date we file our financial statements indicates it is probable that a loss has been incurred, given the likelihood of uncertain future events; and  the amount of the loss can be reasonably estimated. We do not accrue contingencies that might result in gains. We continuously assess contingencies for litigation claims, environmental remediation and other events. See Note 6 for a discussion of contingencies.
Effects of Reference Rate Reform on Financial Reporting	Effects of Reference Rate Reform on Financial Reporting Our Credit Facility uses LIBOR as a benchmark for establishing interest rates but incorporates a transition mechanism for the phase-out of LIBOR. In the event we modify our Credit Facility related to the phase-out of LIBOR, we will evaluate the optional expedients and exceptions under ASU No. 2020-04. The standard allows entities to account for contract modifications as an event that does not require reassessment or remeasurement (i.e., as a continuation of the existing contract).
