Organization, Consolidation and Presentation of Financial Statements [Abstract]
Background	Background General We are a facilities-based technology and communications company that provides a broad array of integrated products and services to our domestic and global business customers and our domestic mass markets customers. We operate one of the world’s most interconnected networks. Our platform empowers our customers to swiftly adjust digital programs to meet immediate demands, create efficiencies, accelerate market access and reduce costs, which allows our customers to rapidly evolve their IT programs to address dynamic changes. Our specific products and services are detailed in Note 3—Revenue Recognition. During 2022 and 2023, we divested components of our business, referenced herein as (i) the Europe, Middle East and Africa ("EMEA") business, divested November 1, 2023, (ii) the incumbent local exchange ("ILEC") business conducted in 20 Midwestern and Southeastern states, divested October 3, 2022 and (iii) the Latin American business, divested August 1, 2022. Refer to Note 2—Divestitures of the Latin American, ILEC and EMEA Businesses in our Annual Report on Form 10-K for the year ended December 31, 2023 for more information on these divestitures. As we determined that none of these divestitures represented a strategic shift for Lumen, they did not meet the criteria to be treated as discontinued operations and we continued to report our operating results for all three of the divested businesses in our consolidated operating results through their respective disposal dates. Basis of Presentation Our consolidated balance sheet as of December 31, 2023, which was derived from our audited consolidated financial statements, and our unaudited interim consolidated financial statements provided herein have been prepared in accordance with the instructions for Form 10-Q. Certain information and note disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") have been condensed or omitted pursuant to rules and regulations of the U.S. Securities and Exchange Commission ("SEC"). However, in our opinion, the disclosures made therein are adequate to make the information presented not misleading. We believe these consolidated financial statements include all normal recurring adjustments necessary to fairly present the results for the interim periods. The consolidated results of operations and cash flows for the first six months of the year are not necessarily indicative of the consolidated results of operations and cash flows that might be expected for the entire year. These consolidated financial statements and the accompanying notes should be read in conjunction with the audited consolidated financial statements and the notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2023. The accompanying consolidated financial statements include our accounts and the accounts of our subsidiaries in which we have a controlling interest. Intercompany amounts and transactions with our consolidated subsidiaries have been eliminated. To simplify the overall presentation of our consolidated financial statements, we report immaterial amounts attributable to noncontrolling interests in certain of our subsidiaries as follows: (i) income attributable to noncontrolling interests in other income (expense), net, (ii) equity attributable to noncontrolling interests in additional paid-in capital and (iii) cash flows attributable to noncontrolling interests in other, net financing activities. We reclassified certain prior period amounts to conform to the current period presentation, including the recategorization of our Business revenue by product category and sales channel in our segment reporting. See Note 3—Revenue Recognition and Note 10—Segment Information for additional information. These changes had no impact on total operating revenue, total operating expenses or net (loss) income for any period. During 2023, we identified errors in our previously reported consolidated financial statements related to accounts receivable and accounts payable which resulted in revisions to certain line items on our December 31, 2022 consolidated balance sheet in prior periods. We have recorded an increase to our accumulated deficit by $63 million, reflected in our January 1, 2023 and June 30, 2023 accumulated deficit in our consolidated statements of stockholders' equity in this report. Refer to Note 1— Background and Summary of Significant Accounting Policies to the consolidated financial statements and accompanying notes in Part II, Item 8 of our Annual Report on Form 10-K for the year ended December 31, 2023 for more information. Operating lease assets are included in Other, net under Goodwill and Other Assets on our consolidated balance sheets. Noncurrent operating lease liabilities are included in Other under Deferred Credits and Other Liabilities on our consolidated balance sheets. There were $5 million and no book overdrafts included in Accounts payable at June 30, 2024 and December 31, 2023, respectively. Change in Accounting Estimates Effective January 1, 2024, we changed our method of depreciation and amortization for ILEC and certain competitive local exchange carriers ("CLEC") fixed assets from the group method of depreciation to straight line by individual asset method. Historically, we have used the group method of depreciation for the property, plant and equipment and amortization of certain intangible capitalized software assets of our ILECs and certain CLECs. Under the group method, for each subsidiary, all like kind assets were combined into common pools and depreciated under composite depreciation rates. Recent business divestitures and asset sales have significantly reduced our composite asset base. We believe the straight-line depreciation method for individual assets is preferable to the group method as it will result in a more precise estimate of depreciation expense and will result in a consistent depreciation method for all our subsidiaries. This change in the method of depreciation is considered a change in accounting estimate inseparable from a change in accounting principle and will result in changes to our depreciation and amortization expense prospectively. The change in accounting estimate had an immaterial impact to our net (loss) income and diluted (loss) earnings per share for the three and six months ended June 30, 2024. Additionally, during the first quarter of 2024, we updated our analysis of economic lives of owned fiber network assets. As of January 1, 2024, we extended the estimated economic life and depreciation period of such assets from 25 years to 30 years to better reflect the physical life of the assets that we have experienced and absence of technological changes that would replace fiber. The change in accounting estimate decreased depreciation expense by approximately $16 million, $12 million net of tax, and $32 million, $24 million net of tax, for the three and six months ended June 30, 2024, respectively, and resulted in an increase of $0.01 and $0.02, respectively, per diluted share for the three and six months ended June 30, 2024. Summary of Significant Accounting Policies Refer to the significant accounting policies described in Note 1— Background and Summary of Significant Accounting Policies to the consolidated financial statements and accompanying notes in Part II, Item 8 of our Annual Report on Form 10-K for the year ended December 31, 2023. Recently Adopted Accounting Pronouncements Supplier Finance Programs On January 1, 2023, we adopted Accounting Standards Update ("ASU") 2022-04, “Liabilities-Supplier Finance Program (Subtopic 405-50): Disclosure of Supplier Finance Program Obligations ” (“ASU 2022-04”). These amendments require that a company that uses a supplier finance program in connection with the purchase of goods or services disclose sufficient information about the program to allow a user of financial statements to understand the program’s nature, program activity during the period, changes from period to period and the potential magnitude of program transactions. The adoption of ASU 2022-04 did not have a material impact on our consolidated financial statements. Credit Losses On January 1, 2023, we adopted ASU 2022-02, “ Financial Instruments-Credit Losses (Topic 326): Troubled Debt Restructurings (“TDR”) and Vintage Disclosures ” (“ASU 2022-02”). The ASU eliminates the TDR recognition and measurement guidance, enhances existing disclosure requirements and introduces new requirements related to certain modifications of receivables made to borrowers experiencing financial difficulty. The adoption of ASU 2022-02 did not have a material impact on our consolidated financial statements. Adoption of Other ASU With No Impact On January 1, 2024, we adopted ASU 2023-01, “ Leases (Topic 842): Common Control Arrangements ”, and ASU 2022-03, “ Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions ”. The adoption of these ASUs did not have any impact on our consolidated financial statements. Recently Issued Accounting Pronouncements In December 2023, the Financial Accounting Standards Board (“FASB”) issued ASU 2023-09 “ Income Taxes (Topic 740): Improvements to Income Tax Disclosures ” (“ASU 2023-09”). This ASU requires public business entities to annually (i) disclose specific categories in the rate reconciliation and (ii) provide additional information for reconciling items that meet a quantitative threshold (if the effect of those reconciling items is equal to or greater than 5 percent of the amount computed by multiplying pretax income or loss by the applicable statutory income tax rate). ASU 2023-09 will become effective for us in fiscal year 2025 and early adoption is permitted. As of June 30, 2024, we had not early adopted this ASU and are currently evaluating its impact on our consolidated financial statements, including our annual disclosure within our Income Taxes note. In November 2023, the FASB issued ASU 2023-07, “ Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures ” (“ASU 2023-07”). This ASU is intended to improve reportable segment disclosure requirements primarily through enhanced disclosures about significant segment expenses. This ASU will become effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. As of June 30, 2024, we had not early adopted this ASU and are currently evaluating its impact on our consolidated financial statements, including on the accompanying annual disclosure within our Segment Information note.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill, Customer Relationships and Other Intangible Assets	Goodwill, Customer Relationships and Other Intangible Assets Goodwill, customer relationships and other intangible assets consisted of the following: June 30, 2024 December 31, 2023 (Dollars in millions) Goodwill $ 1,964 1,964 Indefinite-lived intangible assets $ 9 9 Other intangible assets subject to amortization: Customer relationships, less accumulated amortization of $4,201 and $4,248 (1) 3,501 3,811 Capitalized software, less accumulated amortization of $4,017 and $4,045 (1) 1,538 1,564 Trade names, patents and other, less accumulated amortization of $79 and $72 79 86 Total other intangible assets, net $ 5,127 5,470 ______________________________________________________________________ (1) Certain customer relationships with a gross carrying value of $352 million and capitalized software with a gross carrying value of $153 million became fully amortized during 2023 and were retired during the first quarter of 2024. As of June 30, 2024, the gross carrying amount of goodwill, customer relationships, indefinite-lived and other intangible assets was $15.4 billion. Our goodwill was derived from numerous acquisitions where the purchase price exceeded the fair value of the net assets acquired. We report our results within two segments: Business and Mass Markets. See Note 10—Segment Information for more information on these segments. We assigned no goodwill to our Business segment as of June 30, 2024 and December 31, 2023. We assigned approximately $2.0 billion of goodwill to our Mass Markets segment as of both June 30, 2024 and December 31, 2023. Total goodwill as of both June 30, 2024 and December 31, 2023 was net of accumulated impairment losses of $21.7 billion. We are required to assess our goodwill and other indefinite-lived intangible assets for impairment annually, or, under certain circumstances, more frequently, such as when events or changes in circumstances indicate there may be impairment. We are required to write down the value of goodwill only when our assessment determines the carrying value of equity of any of our reporting units exceeds its fair value. Our annual impairment assessment date for goodwill is October 31, at which date we assess our reporting units. Our annual impairment assessment date for indefinite-lived intangible assets other than goodwill is December 31. As of June 30, 2024, we had three reporting units, which are (i) Mass Markets, (ii) North American Business ("NA Business") and (iii) Asia Pacific region ("APAC"). Our reporting units are not discrete legal entities with discrete full financial statements. Our assets and liabilities are employed in and relate to the operations of multiple reporting units. When we assess goodwill for impairment, we compare the estimated fair value of each reporting unit's equity to the carrying value of equity that we assign to the reporting unit. If the estimated fair value of the reporting unit is greater than the carrying value, we conclude that no impairment exists. If the estimated fair value of the reporting unit is less than the carrying value, we record a non-cash impairment charge equal to the excess amount. Depending on the facts and circumstances, we typically estimate the fair value of our reporting units by considering either or both of (i) a discounted cash flow method, which is based on the present value of projected cash flows over a discrete projection period and a terminal value, which is based on the expected normalized cash flows of the reporting units following the discrete projection period, and (ii) a market approach, which includes the use of market multiples of publicly-traded companies whose services are comparable to ours . Second Quarter 2023 Goodwill Impairment Analysis During the second quarter of 2023, we determined circumstances existed indicating it was more likely than not that the carrying value of our reporting units exceeded their fair value. Given the continued erosion in our market capitalization at the time, we determined our quantitative impairment analysis would accurately estimate the fair value of our reporting units using only the market approach. Applying this approach, we utilized company comparisons and analyst reports within our industry which supported a range of fair values derived from annualized revenue and Earnings Before Interest, Tax, Depreciation and Amortization ("EBITDA") multiples between 1.5x and 4.3x and 4.6x and 10.5x, respectively. In determining the fair value of each reporting unit, we used revenue and EBITDA multiples below these comparable market multiples. The estimated fair values of the reporting units determined in connection with our impairment analysis in the second quarter of 2023 resulted in no control premium, which we determined to be reasonable based on our market capitalization relative to recent transactions. For the three months ended June 30, 2023, based on our assessments performed with respect to the reporting units as described above, we concluded the estimated fair value of certain of our reporting units was less than their carrying value of equity. As a result, we recorded a non-cash, non-tax-deductible goodwill impairment charge of $8.8 billion for the three months ended June 30, 2023. The market approach that we used in the quarter ended June 30, 2023 incorporated estimates and assumptions related to the forecasted results for the remainder of the year, including revenues, expenses, and the achievement of certain strategic initiatives. In developing the market multiples applicable for each reporting unit, we considered observed trends of our industry peers. Our assessment included many factors that required significant judgment. Alternative interpretations of these factors could have resulted in different conclusions regarding the size of our impairments. Total amortization expense for finite-lived intangible assets for the three months ended June 30, 2024 and 2023 totaled $277 million and $263 million, respectively, and for the six months ended June 30, 2024 and 2023 totaled $549 million and $523 million, respectively. We estimate that future total amortization expense for finite-lived intangible assets will be as follows: (Dollars in millions) 2024 (remaining six months) $ 479 2025 900 2026 847 2027 759 2028 688 2029 and thereafter 1,445

Credit Loss [Abstract]
Credit Losses on Financial Instruments	Credit Losses on Financial Instruments To assess our expected credit losses on financial instruments, we aggregate financial assets with similar risk characteristics to monitor their credit quality or deterioration over the life of such assets. We periodically monitor certain risk characteristics within our aggregated financial assets and revise their composition accordingly, to the extent internal and external risk factors change. We separately evaluate financial assets that do not share risk characteristics with other financial assets. Our financial assets measured at amortized cost primarily consist of accounts receivable. We use a loss rate method to estimate our allowance for credit losses. Our determination of the current expected credit loss rate begins with our review of historical loss experience as a percentage of accounts receivable. We measure our historical loss period based on the average days to recognize accounts receivable as credit losses. When asset specific characteristics and current conditions change from those in the historical period, due to changes in our credit and collections strategy, certain classes of aged balances, or credit loss and recovery policies, we perform a qualitative and quantitative assessment to adjust our historical loss rate. We use regression analysis to develop an expected loss rate using historical experience and economic data over a forecast period. We measure our forecast period based on the average days to collect payment on billed accounts receivable. To determine our current allowance for credit losses, we combine the historical and expected credit loss rates and apply them to our period end accounts receivable. If there is an unexpected deterioration of a customer's financial condition or an unexpected change in economic conditions, including macroeconomic events, we assess the need to adjust the allowance for credit losses. Any such resulting adjustments would affect earnings in the period that adjustments are made. The assessment of the correlation between historical observed default rates, current conditions and forecasted economic conditions requires judgment. Alternative interpretations of these factors could have resulted in different conclusions regarding our allowance for credit losses. The amount of credit loss is sensitive to changes in circumstances and forecasted economic conditions. Our historical credit loss experience, current conditions and forecast of economic conditions may also not be representative of the customers' actual default experience in the future, and we may use methodologies that differ from those used by other companies. The following table presents the activity of our allowance for credit losses by accounts receivable portfolio for the six months ended June 30, 2024: Business Mass Markets Total (Dollars in millions) As of December 31, 2023 $ 36 31 67 Provision for expected losses 13 26 39 Write-offs charged against the allowance (19) (31) (50) Recoveries collected 4 2 6 Ending balance at June 30, 2024 $ 34 28 62

(2) Reflects approximately $26 million of term loan installment payments made between the Effective Date and June 30, 2024. In evaluating the terms of the TSA transaction, we determined for certain of our creditors that the new debt instruments were substantially different than pre-existing debt and therefore constituted an extinguishment of old debt and establishment of new debt for which we recorded a $275 million gain on extinguishment in the first quarter of 2024. This new debt was recorded at fair value generating a reduction to debt of $492 million which was included in our aggregate Net gain on early retirement of debt of $278 million, recognized in Other income (expense), net in our consolidated statement of operations for the six months ended June 30, 2024. The remaining creditors’ newly-issued debt was not substantially different under the terms of the TSA transaction and was treated under modification accounting rules. In conjunction with the TSA transaction, we paid $209 million in lender fees and $174 million in additional third-party costs. Of these amounts, $157 million of lender fees were an offset to the gain on extinguishment and $112 million in third-party costs were recorded to Selling, general and administrative expense in our consolidated statement of operations for the six months ended June 30, 2024. In accordance with GAAP provisions for modification and extinguishment accounting, $52 million in lender fees and $62 million in third-party costs, respectively, were capitalized and will be amortized over the terms of the newly-issued indebtedness. During the second quarter of 2024, we repurchased a total of approximately $75 million aggregate principal of Lumen 5.625% senior notes due 2025 and Lumen 7.200% senior notes due 2025. These repurchases resulted in an aggregate net gain of $3 million, which is included in our aggregate Net gain on early retirement of debt in Other income (expense), net in our consolidated statement of operations for the six months ended June 30, 2024. For information on various issuances, exchanges or payments of long-term indebtedness by Lumen or its subsidiaries during 2023, see Note 7—Long-Term Debt and Credit Facilities in Item 8 of Part II of our Annual Report on Form 10-K for the year ended December 31, 2023. Lumen Credit Agreements As further described in our prior periodic reports, Lumen may prepay amounts outstanding under its new Superpriority Term Loan A Facility and new Superpriority Term Loan B Facilities at any time without premium or penalty. If no amounts are outstanding under its Superpriority Series B Revolving Credit Facility, Lumen may prepay amounts outstanding under the Series A Revolving Credit Facility without premium or penalty. The new Superpriority Term Loan A Facility and new Superpriority Term Loan B Facilities require Lumen to make quarterly amortization payments of 1.25% and 0.25%, respectively, of the initial principal amount and certain specified mandatory prepayments upon the occurrence of certain transactions. At June 30, 2024, no borrowings were outstanding under Lumen’s Series A Revolving Credit Facility with commitments of approximately $489 million or Series B Revolving Credit Facility with commitments of approximately $467 million. Level 3 Financing Credit Agreement As further described in our prior periodic reports, amounts outstanding under Level 3 Financing's new Credit Agreement may be prepaid at any time, subject to a premium of (i) 2.00% of the aggregate principal amount if prepaid on or prior to the 12-month anniversary of the Effective Date and (ii) 1.00% of the aggregate principal amount if prepaid after the 12-month anniversary of the Effective Date and on or prior to the 24-month anniversary of the Effective Date. The new Level 3 facilities established under the new Credit Agreement require Level 3 Financing to make certain specified mandatory prepayments upon the occurrence of certain transactions. Senior Notes The Company’s consolidated indebtedness at June 30, 2024 included: • superpriority senior secured notes issued by Lumen; • first and second lien secured notes issued by Level 3 Financing; and • senior unsecured notes issued by Lumen, Level 3 Financing, Qwest Corporation, and Qwest Capital Funding, Inc. All of these notes carry fixed interest rates and all principal is due on the notes’ respective maturity dates, which rates and maturity dates are summarized in the table above. The Level 3 Financing secured notes outstanding at June 30, 2024 include $1.575 billion in aggregate principal of privately placed first lien notes maturing 2029 issued in the first quarter of 2024. Of this amount, $1.325 billion was issued in exchange for cash proceeds, $200 million was issued in exchange for Lumen 4.000% senior secured notes and $50 million was issued as payment of non-cash lender fees. Except for a limited number of senior notes issued by Qwest Corporation, the issuer generally can redeem the notes, at its option, in whole or in part, (i) pursuant to a fixed schedule of pre-established redemption prices, (ii) pursuant to a “make whole” redemption price or (iii) under certain other specified limited conditions. Letters of Credit At June 30, 2024, we had $221 million undrawn letters of credit outstanding, $217 million of which were issued under Lumen's revolving credit facilities, $2 million of which were issued under our $225 million uncommitted letter of credit facility and $2 million of which were issued under a separate facility maintained by one of our subsidiaries (the full amount of which is collateralized by cash that is reflected on our consolidated balance sheets as restricted cash within Other, net under Goodwill and Other Assets). Certain Guarantees and Security Interests Lumen’s obligations under its Superpriority Revolving/Term Loan A Credit Agreement are unsecured, but certain of Lumen’s subsidiaries have provided or, in certain cases after receiving necessary regulatory approvals, will provide an unconditional guarantee of payment of Lumen’s obligations (such entities, the “Lumen Guarantors”) and certain of such guarantees will be secured by a lien on substantially all of the assets of the applicable Lumen Guarantors. Level 3, Level 3 Financing and certain of Level 3 Financing’s subsidiaries have provided or, in certain cases after receiving necessary regulatory approvals, will provide an unconditional guarantee of payment of Lumen’s obligations under its Series A Revolving Credit Facility of up to $150 million and under its Series B Revolving Credit Facility of up to $150 million, in each case secured by a lien on substantially all of their assets (such entities, the “Level 3 Collateral Guarantors”). The guarantee by the Level 3 Collateral Guarantors may be reduced or terminated under certain circumstances. Qwest Corporation and certain of its subsidiaries have provided an unsecured guarantee of collection of Lumen’s obligations under its revolving credit facilities and Superpriority Term Loan A Facility (the “Qwest Guarantors”). Lumen’s obligations under the Superpriority Term Loan B Credit Agreement are unsecured. The term loans issued under this agreement are guaranteed by the Lumen Guarantors and the Qwest Guarantors on the same basis as those entities guarantee Lumen’s obligations under its Superpriority Revolving/Term Loan A Credit Agreement. Level 3 Financing’s obligations under its new Credit Agreement are secured by a first lien on substantially all of its assets (subject, in certain cases, to receipt of necessary regulatory approvals). In addition, the other Level 3 Collateral Guarantors have or, in certain cases after receiving necessary regulatory approvals, will provide an unconditional guarantee of payment of Level 3 Financing’s obligations under its new Credit Agreement secured by a lien on substantially all of their assets. Lumen’s superpriority secured senior notes are guaranteed by the Lumen Guarantors and the Qwest Guarantors on the same basis as those entities guarantee Lumen’s obligations under its Superpriority Revolving/Term Loan A Credit Agreement. Level 3 Financing’s obligations under its first lien notes are secured by a first lien on substantially all of its assets (subject, in certain cases, to receipt of necessary regulatory approvals), and are guaranteed by the other Level 3 Collateral Guarantors (or, for certain such guarantors, will be guaranteed upon the receipt of required regulatory approvals) on the same basis as the guarantees provided by such entities under its new Credit Agreement. Level 3 Financing’s obligations under its second lien notes are secured by a second lien on substantially all of its assets (subject, in certain cases, to receipt of necessary regulatory approvals), and are guaranteed by the other Level 3 Collateral Guarantors (or, for certain such guarantors, will be guaranteed upon the receipt of required regulatory approvals) on the same basis as the guarantees provided by such entities under its new Credit Agreement, except the lien securing such guarantees is a second lien. Level 3 Financing's obligation under one of its series of unsecured notes are guaranteed by Level 3 and one of Level 3 Financing's subsidiaries. The senior unsecured notes issued by Qwest Capital Funding, Inc. are guaranteed by its parent, Qwest Communications International Inc. Covenants Lumen Under its Superpriority Revolving/Term Loan A Credit Agreement, Lumen may not permit: (i) its maximum total net leverage ratio to exceed 5.75 to 1.00 as of the last day of each fiscal quarter, stepping down to 5.50 to 1.00 with respect to each fiscal quarter ending after December 31, 2024 and further stepping down to 5.25 to 1.00 with respect to each fiscal quarter ending after December 31, 2025; or (ii) its interest coverage ratio as of the last day of any test period to be less than 2.00 to 1.00. Lumen’s superpriority credit agreements and superpriority senior secured notes contain various representations and warranties and extensive affirmative and negative covenants. Such covenants include, among other things and subject to certain significant exceptions, restrictions on our ability to declare or pay dividends, repurchase stock, repay certain other indebtedness, create liens, incur additional indebtedness, make investments, engage in transactions with our affiliates, dispose of assets and merge or consolidate with other persons. Lumen’s senior unsecured notes were issued under four separate indentures. These indentures restrict Lumen’s ability to (i) incur, issue or create liens upon its property and (ii) consolidate with or merge into, or transfer or lease all or substantially all of its assets to any other party. Under certain circumstances in connection with a “change of control” of Lumen, Lumen will be required to make an offer to repurchase each series of these senior notes (other than two of its older series of notes) at a price of 101% of the principal amount redeemed, plus accrued and unpaid interest. Level 3 Level 3 Financing's new Credit Agreement and first and second lien secured notes contain various representations and extensive affirmative and negative covenants. Such covenants include, among other things and subject to certain significant exceptions, restrictions on their ability to declare or pay dividends, repay certain other indebtedness, create liens, incur additional indebtedness, make investments, dispose of assets and merge or consolidate with other persons. Also, under certain circumstances in connection with a “change of control” of Level 3 or Level 3 Financing, Level 3 Financing will be required to make an offer to repurchase each series of its outstanding senior notes at a price of 101% of the principal amount redeemed, plus accrued and unpaid interest. Qwest Companies The senior notes of Qwest Corporation were issued under indentures dated April 15, 1990 and October 15, 1999. These indentures contain restrictions on the incurrence of liens and the consummation of certain transactions substantially similar to the above-described covenants in the indentures governing Lumen’s senior unsecured notes (but contain no mandatory repurchase provisions). The senior notes of Qwest Capital Funding, Inc. were issued under an indenture dated June 29, 1998 containing terms substantially similar to those set forth in Qwest Corporation's indentures. Compliance As of June 30, 2024, Lumen Technologies, Inc. believes it and its subsidiaries were in compliance with the provisions and financial covenants in their respective material debt agreements in all material respects. Guarantees Lumen does not guarantee the debt of any unaffiliated parties, but, as noted above, as of June 30, 2024, certain of its key subsidiaries guaranteed (i) its debt outstanding under its SP Credit Agreements, its superpriority senior secured notes and its $225 million letter of credit facility and (ii) the outstanding term loans or senior secured notes issued by certain other subsidiaries. As further noted above, several of the subsidiaries guaranteeing these obligations have pledged substantially all of their assets to secure certain of their respective guarantees.

Severance

Severance	6 Months Ended

Restructuring and Related Activities [Abstract]
Severance	Severance Periodically, we reduce our workforce and accrue liabilities for the related severance costs. These workforce reductions result primarily from the progression or completion of our post-acquisition integration plans, increased competitive pressures, cost reduction initiatives, process improvements through automation and reduced workloads due to reduced demand for certain services. During April 2024, we reduced our workforce by approximately 6% as a part of our efforts to change our workforce composition to reflect our ongoing transformation and cost reduction opportunities that align with our shapeshifting and focus on our strategic priorities. As a result of this plan, we incurred severance and related costs of approximately $103 million. We have not incurred, and do not expect to incur, material impairment or exit costs related to this workforce reduction. Changes in our accrued liabilities for severance expenses were as follows: Severance (Dollars in millions) Balance at December 31, 2023 $ 18 Accrued to expense 107 Payments, net (106) Balance at June 30, 2024 $ 19

Net periodic benefit expense for the Lumen Combined Pension Plan (the "Combined Pension Plan" or the "Plan") includes the following components: Combined Pension Plan Three Months Ended June 30, Six Months Ended June 30, 2024 2023 2024 2023 (Dollars in millions) Service cost $ 6 6 12 12 Interest cost 62 67 125 135 Expected return on plan assets (69) (72) (136) (143) Recognition of prior service credit (1) (1) (3) (3) Recognition of actuarial loss 26 26 54 51 Net periodic pension expense $ 24 26 52 52 Net periodic benefit expense for our post-retirement benefit plans includes the following components: Post-Retirement Benefit Plans Three Months Ended June 30, Six Months Ended June 30, 2024 2023 2024 2023 (Dollars in millions) Service cost $ 1 2 2 3 Interest cost 24 25 47 51 Recognition of prior service credit (2) (2) (4) (4) Recognition of actuarial gain (5) (5) (9) (10) Special termination benefits charge 2 — 2 — Net periodic post-retirement benefit expense $ 20 20 38 40 Service costs for our pension plans and post-retirement benefit plans are included in the Cost of services and products (exclusive of depreciation and amortization) and Selling, general and administrative line items on our consolidated statements of operations and all other costs listed above are included in Other income (expense), net on our consolidated statements of operations for the three and six months ended June 30, 2024 and 2023. As a result of ongoing efforts to reduce our workforce, we recognized a one-time charge of $2 million during the three months ended June 30, 2024 for special termination benefit enhancements paid to certain eligible employees upon voluntary retirement. Our Combined Pension Plan contains provisions that allow us, from time to time, to offer lump sum payment options to certain former employees in settlement of their future retirement benefits. We record an accounting settlement charge, consisting of the recognition of certain deferred costs of the pension plan associated with these lump sum payments, only if in the aggregate they exceed or are probable to exceed the sum of the annual service and interest costs for the plan’s net periodic pension benefit cost, which represents the settlement accounting threshold. The amount of any future non-cash settlement charges will be dependent on several factors, including the total amount of our future lump sum benefit payments.

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Fair Value of Financial Instruments Our financial instruments consist of cash, cash equivalents, restricted cash, accounts receivable, accounts payable, long-term debt (excluding finance lease and other obligations), interest rate swap contracts, certain equity investments and certain indemnification obligations. Due primarily to their short-term nature, the carrying amounts of our cash, cash equivalents, restricted cash, accounts receivable and accounts payable approximate their fair values. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between independent and knowledgeable parties who are willing and able to transact for an asset or liability at the measurement date. We use valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs when determining fair value and then we rank the estimated values based on the reliability of the inputs using the below-described fair value hierarchy. We determined the fair values of our long-term debt, including the current portion, based on quoted market prices where available or, if not available, based on inputs other than quoted market prices in active markets that are either directly or indirectly observable such as discounted future cash flows using current market interest rates. The three input levels in the hierarchy of fair value measurements are defined by the FASB generally as follows: Input Level Description of Input Level 1 Observable inputs such as quoted market prices in active markets. Level 2 Inputs other than quoted prices in active markets that are either directly or indirectly observable. Level 3 Unobservable inputs in which little or no market data exists. The following table presents the carrying amounts and estimated fair values of our financial assets and liabilities as of June 30, 2024 and December 31, 2023: June 30, 2024 December 31, 2023 Input Carrying Fair Carrying Fair (Dollars in millions) Long-term debt, excluding finance lease and other obligations 2 $ 18,333 13,020 19,703 13,304 Indemnifications related to the sale of the Latin American business (1) 3 91 86 86 86 ______________________________________________________________________ (1) Nonrecurring fair value is measured as of August 1, 2022. Investment Held at Net Asset Value We hold an investment in a limited partnership created as a holding company for various investments. As of June 30, 2024, the underlying investments held by the limited partnership were traded in active markets and, as such, we account for our investment in the limited partnership using net asset value ("NAV"). Subject to restrictions imposed by law and other provisions of the limited partnership agreement, the general partner has sole discretion as to the amounts and timing of distributions of partnership assets to partners. The following table summarizes the net asset value of our investment in this limited partnership.

Segment Reporting [Abstract]
Segment Information	Segment Information We report our results within two segments: Business and Mass Markets. Under our Business segment we provide products and services to meet the needs of our enterprise and wholesale customers under five distinct sales channels: Large Enterprise, Mid-Market Enterprise, Public Sector, Wholesale, and International and Other. For Business segment revenue, we report the following product categories: Grow, Nurture, Harvest, and Other, in each case through the sales channels outlined above. The Business segment included the results of our EMEA business prior to its sale on November 1, 2023. Under our Mass Markets Segment, we provide products and services to residential and small business customers. We report the following product categories: Fiber Broadband, Other Broadband, and Voice and Other. See detailed descriptions of these product and service categories in Note 3—Revenue Recognition. As described in more detail below, our segments are managed based on the direct costs of providing services to applicable customers and directly associated selling, general and administrative costs (primarily salaries and commissions). Shared costs are managed separately and included in "other unallocated expense" in the table included below under the heading "— Revenue and Expenses". As referenced above, we reclassified certain prior period amounts to conform to the current period presentation. See Note 1— Background for additional detail on these changes. The following tables summarize our segment results for the three and six months ended June 30, 2024 and 2023, based on the segment categorization we were operating under at June 30, 2024.

Our segment revenue is based upon each customer's classification. We report our segment revenue based upon all services provided to that segment's customers. Our segment expenses include specific cost of service expenses incurred as a direct result of providing services and products to segment customers, along with selling, general and administrative expenses that are directly associated with specific segment customers or activities. We have not allocated assets or debt to specific segments. The following items are excluded from our segment results, because they are centrally managed and not monitored by or reported to our chief operating decision maker by segment: • network expenses not incurred as a direct result of providing services and products to segment customers and centrally managed expenses such as Finance, Human Resources, Legal, Marketing, Product Management and IT, all of which are reported as "other unallocated expense" in the table below; • depreciation and amortization expense; • goodwill or other impairments; • interest expense; • stock-based compensation; and • other income and expense items.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies and Other Items	Commitments, Contingencies and Other Items We are subject to various claims, legal proceedings and other contingent liabilities, including the matters described below, which individually or in the aggregate could materially affect our financial condition, future results of operations or cash flows. We review our litigation accrual liabilities on a quarterly basis, but in accordance with applicable accounting guidelines only establish accrual liabilities when losses are deemed probable and reasonably estimable and only revise previously established accrual liabilities when warranted by changes in circumstances, in each case based on then-available information. As such, as of any given date we could have exposure to losses under proceedings as to which no liability has been accrued or as to which the accrued liability is inadequate. Subject to these limitations, at June 30, 2024, we had accrued $82 million in the aggregate for our litigation and non-income tax contingencies, which is included in Other under Current Liabilities or Other under Deferred Credits and Other Liabilities in our consolidated balance sheet as of such date. We cannot at this time estimate the reasonably possible loss or range of loss, if any, in excess of this $82 million accrual due to the inherent uncertainties and speculative nature of contested proceedings. The establishment of an accrual does not mean that actual funds have been set aside to satisfy a given contingency. Thus, the resolution of a particular contingency for the amount accrued could have no effect on our results of operations but nonetheless could have an adverse effect on our cash flows. In this Note, when we refer to a class action as "putative" it is because a class has been alleged, but not certified, in that matter. Principal Proceedings Shareholder Class Action Suits Houser. Lumen and certain Lumen Board of Directors members and officers were named as defendants in a putative shareholder class action lawsuit filed on June 12, 2018 in the Boulder County District Court of the state of Colorado, captioned Houser et al. v. CenturyLink, et al. The original complaint asserted claims on behalf of a putative class of former Level 3 shareholders who became CenturyLink, Inc. shareholders as a result of our acquisition of Level 3. It alleged that the proxy statement provided to the Level 3 shareholders failed to disclose various material information of several kinds, including information about strategic revenue, customer loss rates, and customer account issues, among other items. The original complaint sought damages, costs and fees, rescission, rescissory damages, and other equitable relief. In May 2020, the court dismissed the original complaint. Plaintiffs appealed that decision, and in March 2022, the appellate court affirmed the district court's order in part and reversed it in part. It then remanded the case to the district court for further proceedings. Plaintiff filed an amended complaint asserting the same claims and prayer for relief, and we filed a motion to dismiss. The court granted our motion to dismiss in May 2023 and Plaintiffs have appealed that dismissal. In re Lumen Technologies, Inc. Securities Litigation. On March 3, 2023, a purported shareholder of Lumen filed a putative class action complaint originally captioned Voigt et al. v. Lumen Technologies, et al., now In re Lumen Technologies, Inc. Securities Litigation, Case 3:23-cv-00286-TAD-KDM, in the U.S. District Court for the Western District of Louisiana. The complaint alleges that Lumen and certain of its current or former officers violated the federal securities laws by omitting or misstating material information related to Lumen’s expansion of its Quantum Fiber business. The court appointed a lead plaintiff who filed an amended complaint, seeking money damages, attorneys’ fees and costs, and other relief. In re Lumen Technologies, Inc. Securities Litigation II. On September 15, 2023, a purported shareholder of Lumen filed a putative class action complaint captioned Glauber, et al. v. Lumen Technologies, now In re Lumen Technologies, Inc. Securities Litigation II, Case 3:23-cv-01290, in the U.S. District Court for the Western District of Louisiana. The complaint alleged that Lumen and certain of its current or former officers violated the federal securities laws by omitting or misstating material information related to Lumen’s responsibility for environmental degradation allegedly caused by the lead sheathing of certain telecommunications cables. The court appointed lead plaintiffs who filed an amended complaint, seeking money damages, attorneys’ fees and costs, and other relief. Derivative Litigation On June 11, 2024, a purported shareholder of Lumen filed a shareholder derivative complaint on behalf of Lumen captioned Brown v. Johnson, et al., Case 3:24-cv-000798-TAD-KDM, in the U.S. District Court for the Western District of Louisiana. The complaint alleges claims for breach of fiduciary duty, violations of the federal securities laws, and other causes of action against current and former officers and directors of Lumen relating to placement or presence of lead-sheathed telecommunications cables. The complaint seeks damages, injunctive relief, and attorneys' fees. Lead-Sheathed Cable Environmental Litigation Parish of St. Mary. On July 9, 2024, a putative class action complaint was filed in the 16th Judicial District Court for the Parish of St. Mary, State of Louisiana, case no. 138575, asserting claims on behalf of all parishes, municipalities, and citizens owning real properties in the State of Louisiana that have been affected by lead-sheathed telecommunications cables installed by AT&T and Lumen or their predecessors. The complaint seeks damages and injunctive relief under Louisiana state law. Blum . On November 6, 2023, a putative class action complaint was filed in the 16th Judicial District Court for the Parish of St. Mary, State of Louisiana, case no. 137935, asserting claims on behalf of all citizens owning real properties in the State of Louisiana that have been affected by lead-sheathed telecommunications cables installed by AT&T, BellSouth, Verizon, and Lumen or their predecessors. The complaint seeks damages and injunctive relief under Louisiana state law. The case has been removed to Federal Court in the United States District Court Western District of Louisiana Lafayette Division, case no. 6:23-CV-01748. State Tax Suits Since 2012, a number of Missouri municipalities have asserted claims in the Circuit Court of St. Louis County, Missouri, alleging that we and several of our subsidiaries have underpaid taxes. These municipalities are seeking, among other things, declaratory relief regarding the application of business license and gross receipts taxes and back taxes from 2007 to the present, plus penalties and interest. In a February 2017 ruling in connection with one of these pending cases, the court entered an order awarding the plaintiffs $4 million and broadening the tax base on a going-forward basis. We appealed that decision to the Missouri Supreme Court. In December 2019, it affirmed the circuit court's order in some respects and reversed it in others, remanding the case to the circuit court for further proceedings. The Missouri Supreme Court's decision reduced our exposure in the case. In a June 2021 ruling in one of the pending cases, another trial court awarded the cities of Columbia and Joplin approximately $55 million, plus statutory interest. On appeal, the Missouri Court of Appeals affirmed in part and reversed in part, vacated the judgment and remanded the case to the trial court with instructions for further proceedings consistent with the Missouri Supreme Court's decision. Billing Practices Suits In June 2017, a former employee filed an employment lawsuit against us claiming that she was wrongfully terminated for alleging that we charged some of our retail customers for products and services they did not authorize. Thereafter, based in part on the allegations made by the former employee, several legal proceedings were filed, including consumer class actions in federal and state courts, a series of securities investor class actions in federal courts and several shareholder derivative actions in federal and Louisiana state courts. The derivative cases were brought on behalf of CenturyLink, Inc. against certain current and former officers and directors of the Company and seek damages for alleged breaches of fiduciary duties. We have settled the consumer and securities investor class actions and the derivative actions. We have engaged in discussions regarding related claims with a number of state attorneys general, and have entered into agreements settling certain of the consumer practices claims asserted by several state attorneys general. December 2018 Outage Proceedings We experienced an outage on one of our transport networks that impacted voice, IP, 911, and transport services for some of our customers between the 27th and 29th of December 2018. We believe that the outage was caused by a faulty network management card from a third-party equipment vendor. The FCC and four states initiated formal investigations. In November 2020, following the FCC's release of a public report on the outage, we negotiated a settlement which was released by the FCC in December 2020. The amount of the settlement was not material to our financial statements. In December 2020, the Staff of the Washington Utilities and Transportation Commission ("WUTC") filed a complaint against us based on the December 2018 outage, seeking penalties of approximately $7 million for alleged violations of Washington regulations and laws. The Washington Attorney General's office sought penalties of $27 million. Following trial before the WUTC, it issued an order in June 2023 penalizing us for approximately $1 million. We and the Washington Attorney General's office have both filed for reconsideration. Those motions are pending. Latin American Tax Litigation and Claims In connection with the 2022 divestiture of our Latin American business, the purchaser assumed responsibility for the Brazilian tax claims described in our prior periodic reports filed with the SEC. We agreed to indemnify the purchaser for amounts paid with respect to the Brazilian tax claims. The value of this indemnification and others associated with the Latin American business divestiture are included in the indemnification amount as disclosed in Note 9—Fair Value of Financial Instruments. Huawei Network Deployment Investigations Lumen has received requests from the following federal agencies for information relating to the use of equipment manufactured by Huawei Technologies Company ("Huawei") in Lumen’s networks. • DOJ. Lumen has received a civil investigative demand from the U.S. Department of Justice in the course of a False Claims Act investigation alleging that Lumen Technologies, Inc. and Lumen Technologies Government Solutions, Inc. failed to comply with certain specified requirements in federal contracts concerning their use of Huawei equipment.  • FCC. The FCC’s Enforcement Bureau issued a Letter of Inquiry to Lumen Technologies, Inc. regarding its written certifications to the FCC that Lumen has complied with FCC rules governing the use of resources derived from the High Cost Program, Lifeline Program, Rural Health Care Program, E-Rate Program, Emergency Broadband Benefit Program, and the Affordable Connectivity Program. Under these programs, federal funds may not be used to facilitate the deployment or maintenance of equipment or services provided by Huawei, a company that the FCC has determined poses a national security threat to the integrity of U.S. communications networks or the communications supply chain. • Team Telecom. The Committee for the Assessment of Foreign Participation in the United States Telecommunications Service Sector (comprised of the U.S. Attorney General, and the Secretaries of the Department of Homeland Security, and the Department of Defense), commonly referred to as Team Telecom, issued questions and requests for information relating to Lumen’s FCC licenses and its use of Huawei equipment. Marshall Fire Litigation On December 30, 2021, a wildfire referred to as the Marshall Fire ignited near Boulder, Colorado. The Marshall Fire killed two people, and it burned thousands of acres, including entire neighborhoods. Approximately 300 lawsuits naming various defendants and asserting various claims for relief have been filed. To date, three of those name our affiliate Qwest Corporation as being at fault: Allstate Fire and Casualty Insurance Company, et al., v. Qwest Corp., et al., Case No. 2023-cv-3048, and Wallace, et al. v. Qwest Corp., et al., Case No. 2023-cv-30488, both of which have been consolidated with Kupfner, et al., v. Public Service Company of Colorado, et al., Case No. 2022-cv-30195. The consolidated proceeding is pending in Colorado District Court, Boulder, Colorado, Preliminary estimates of potential damage claims exceed $2 billion. 911 Surcharge In June 2021, the Company was served with a complaint filed in the Santa Fe County District Court by Phone Recovery Services, LLC (“PRS”), acting on behalf of the State of New Mexico. The complaint claims Qwest Corporation and CenturyTel of the Southwest have violated the New Mexico Fraud Against Taxpayers Act since 2004 by failing to bill, collect and remit certain 911 surcharges from customers. Through pre-trial proceedings, the Court has narrowed the issues to be resolved by jury, ruling that Lumen bears the burden of proving that its actions were reasonable or known and approved by the State. Other Proceedings, Disputes and Contingencies From time to time, we are involved in other proceedings incidental to our business, including patent infringement allegations, regulatory hearings relating primarily to our rates or services, actions relating to employee claims, tax issues, or environmental law issues, grievance hearings before labor regulatory agencies, miscellaneous third-party tort actions, or commercial disputes. We are currently defending several patent infringement lawsuits asserted against us by non-practicing entities, many of which are seeking substantial recoveries. These cases have progressed to various stages and one or more may go to trial within the next twelve months if they are not otherwise resolved. Where applicable, we are seeking full or partial indemnification from our vendors and suppliers. We are subject to various foreign, federal, state and local environmental protection and health and safety laws. From time to time, we are subject to judicial and administrative proceedings brought by various governmental authorities under these laws. Several such proceedings are currently pending, but none is reasonably expected to exceed $300,000 in fines and penalties. In addition, in the past we acquired companies that had installed lead-sheathed cables several decades earlier, or had operated certain manufacturing companies in the first part of the 1900s. Under applicable environmental laws, we could be named as a potentially responsible party for a share of the remediation of environmental conditions arising from the historical operations of our predecessors. The outcome of these other proceedings described under this heading is not predictable. However, based on current circumstances, we do not believe that the ultimate resolution of these other proceedings, after considering available defenses and any insurance coverage or indemnification rights, will have a material adverse effect on us. The matters listed in this Note do not reflect all of our contingencies. For additional information on our contingencies, see Note 18—Commitments, Contingencies and Other Items to the consolidated financial statements and accompanying notes in Part II, Item 8 of our Annual Report on Form 10-K for the year ended December 31, 2023. The ultimate outcome of the above-described matters may differ materially from the outcomes anticipated, estimated, projected or implied by us in certain of our statements appearing above in this Note, and proceedings we currently consider immaterial may ultimately affect us materially.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation Our consolidated balance sheet as of December 31, 2023, which was derived from our audited consolidated financial statements, and our unaudited interim consolidated financial statements provided herein have been prepared in accordance with the instructions for Form 10-Q. Certain information and note disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") have been condensed or omitted pursuant to rules and regulations of the U.S. Securities and Exchange Commission ("SEC"). However, in our opinion, the disclosures made therein are adequate to make the information presented not misleading. We believe these consolidated financial statements include all normal recurring adjustments necessary to fairly present the results for the interim periods. The consolidated results of operations and cash flows for the first six months of the year are not necessarily indicative of the consolidated results of operations and cash flows that might be expected for the entire year. These consolidated financial statements and the accompanying notes should be read in conjunction with the audited consolidated financial statements and the notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2023. The accompanying consolidated financial statements include our accounts and the accounts of our subsidiaries in which we have a controlling interest. Intercompany amounts and transactions with our consolidated subsidiaries have been eliminated. To simplify the overall presentation of our consolidated financial statements, we report immaterial amounts attributable to noncontrolling interests in certain of our subsidiaries as follows: (i) income attributable to noncontrolling interests in other income (expense), net, (ii) equity attributable to noncontrolling interests in additional paid-in capital and (iii) cash flows attributable to noncontrolling interests in other, net financing activities.
Reclassification	We reclassified certain prior period amounts to conform to the current period presentation, including the recategorization of our Business revenue by product category and sales channel in our segment reporting.
Operating Leases	Operating lease assets are included in Other, net under Goodwill and Other Assets on our consolidated balance sheets. Noncurrent operating lease liabilities are included in Other under Deferred Credits and Other Liabilities on our consolidated balance sheets.
Recently Adopted and Issued Accounting Pronouncements	Recently Adopted Accounting Pronouncements Supplier Finance Programs On January 1, 2023, we adopted Accounting Standards Update ("ASU") 2022-04, “Liabilities-Supplier Finance Program (Subtopic 405-50): Disclosure of Supplier Finance Program Obligations ” (“ASU 2022-04”). These amendments require that a company that uses a supplier finance program in connection with the purchase of goods or services disclose sufficient information about the program to allow a user of financial statements to understand the program’s nature, program activity during the period, changes from period to period and the potential magnitude of program transactions. The adoption of ASU 2022-04 did not have a material impact on our consolidated financial statements. Credit Losses On January 1, 2023, we adopted ASU 2022-02, “ Financial Instruments-Credit Losses (Topic 326): Troubled Debt Restructurings (“TDR”) and Vintage Disclosures ” (“ASU 2022-02”). The ASU eliminates the TDR recognition and measurement guidance, enhances existing disclosure requirements and introduces new requirements related to certain modifications of receivables made to borrowers experiencing financial difficulty. The adoption of ASU 2022-02 did not have a material impact on our consolidated financial statements. Adoption of Other ASU With No Impact On January 1, 2024, we adopted ASU 2023-01, “ Leases (Topic 842): Common Control Arrangements ”, and ASU 2022-03, “ Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions ”. The adoption of these ASUs did not have any impact on our consolidated financial statements. Recently Issued Accounting Pronouncements In December 2023, the Financial Accounting Standards Board (“FASB”) issued ASU 2023-09 “ Income Taxes (Topic 740): Improvements to Income Tax Disclosures ” (“ASU 2023-09”). This ASU requires public business entities to annually (i) disclose specific categories in the rate reconciliation and (ii) provide additional information for reconciling items that meet a quantitative threshold (if the effect of those reconciling items is equal to or greater than 5 percent of the amount computed by multiplying pretax income or loss by the applicable statutory income tax rate). ASU 2023-09 will become effective for us in fiscal year 2025 and early adoption is permitted. As of June 30, 2024, we had not early adopted this ASU and are currently evaluating its impact on our consolidated financial statements, including our annual disclosure within our Income Taxes note. In November 2023, the FASB issued ASU 2023-07, “ Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures ” (“ASU 2023-07”). This ASU is intended to improve reportable segment disclosure requirements primarily through enhanced disclosures about significant segment expenses. This ASU will become effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. As of June 30, 2024, we had not early adopted this ASU and are currently evaluating its impact on our consolidated financial statements, including on the accompanying annual disclosure within our Segment Information note.
