SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
Dec. 31, 2024
Accounting Policies [Abstract]
Basis of presentation	Basis of presentation Certain prior period amounts have been reclassified to conform to current period presentation. Additionally, in the year ended December 31, 2024, the Company recognized a $19 million increase in Net earnings attributable to BorgWarner Inc. in the Consolidated Statement of Operations for the correction of misstatements related to certain accruals, of which $12 million related to 2023 (the remainder relates to periods prior to 2023). The Company has evaluated the effect of these out-of-period adjustments for the current reporting period, as well as on the previous interim and annual periods in which they should have been recognized, and concluded that these adjustments are not material to any of the periods affected. As discussed in the Introduction above, as a result of the Spin-Off, the historical results of operations and the financial position of PHINIA for periods prior to the Spin-Off are presented as discontinued operations in these Consolidated Financial Statements. Refer to Note 26, “Discontinued Operations,” to the Consolidated Financial Statements for more information. The Company’s Consolidated Financial Statements reflect the results of acquisitions following the date of the respective acquisition. Refer to Note 2, “Acquisitions and Dispositions,” to the Consolidated Financial Statements for more information.
Use of estimates	Use of estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the accompanying notes, as well as the amounts of revenues and expenses reported during the periods covered by these financial statements and accompanying notes. Actual results could differ from those estimates.
Principles of Consolidation	Principles of consolidation The Consolidated Financial Statements include all majority-owned subsidiaries in which the Company has a controlling financial interest. All inter-company balances and transactions have been eliminated in consolidation.
Change in accounting method	Change in accounting method Historically, certain of the Company’s U.S. inventories (approximately 14% of the Company’s total inventories at December 31, 2023) were accounted for under the last-in, first-out (“LIFO”) method of accounting. During the fourth quarter of 2024, the Company changed the inventory valuation method for those locations from LIFO to the first-in, first-out (“FIFO”) method. FIFO was deemed a preferable method as it better aligns with the accounting practices of the Company’s peers, it more accurately reflects the current value and physical flow of inventory, and it harmonizes the accounting method for the majority of inventories across the Company. Retroactive application of the change to prior periods did not have a material impact on any prior periods’ Consolidated Financial Statements, and therefore the Company recognized the cumulative effect of the change in the fourth quarter of 2024 as a reduction in Cost of sales of $29 million in the Consolidated Statements of Operations, which resulted in an increase in income before taxes of $29 million ($22 million after tax) for the three months ended December 31, 2024 with a corresponding increase in Inventories, net within the Consolidated Balance Sheet as of December 31, 2024.
Joint ventures and equity securities	Joint ventures and equity securities The Company has investments in three unconsolidated joint ventures, NSK-Warner K.K. , Turbo Energy Private Limited, and Fast Warner Intelligent Control Systems Co., Ltd of which the Company owns 50%, 32.6%, and 49.0%, respectively. These joint ventures are non-controlled affiliates in which the Company exercises significant influence but does not have a controlling financial interest and, therefore, are accounted for under the equity method. Generally, under the equity method, the Company’s original investments in these joint ventures are recorded at cost and subsequently adjusted by the Company’s share of equity in income or losses. The Company monitors its equity method investments for indicators of other-than-temporary declines in fair value on an ongoing basis. If such a decline has occurred, an impairment charge is recorded, which is measured as the difference between the carrying value and the estimated fair value. The Company’s investment in these non-controlled affiliates is included within Investments and long-term receivables in the Consolidated Balance Sheets. The Company’s share of equity in income or losses is included in Equity in affiliates’ earnings, net of tax in the Consolidated Statements of Operations. The Company also has certain investments for which it does not have the ability to exercise significant influence (generally when ownership interest is less than 20%). The Company’s investment in these equity securities is included within Investments and long-term receivables in the Consolidated Balance Sheet. Refer to Note 10, “Other Current and Non-Current Assets,” to the Consolidated Financial Statements for more information. Interests in privately held companies that do not have readily determinable fair values are accounted for using the measurement alternative under ASC Topic 321, “Investments - Equity Securities,” which includes monitoring on an ongoing basis for indicators of impairments or upward adjustments. These equity securities are measured at cost less impairments, adjusted for observable price changes in orderly transactions for the identical or similar investment of the same issuer. If the Company determines that an indicator of impairment or upward adjustment is present, an adjustment is recorded, which is measured as the difference between carrying value and estimated fair value. Estimated fair value is generally determined using an income approach on discounted cash flows or negotiated transaction values. Equity securities that have readily determinable fair values are measured at fair value. Equity securities that do not have a readily determinable fair value and which provide a net asset value (“NAV”) or its equivalent, are valued using NAV as a practical expedient. Changes in fair value and NAV are recorded in Unrealized and realized loss on equity and debt securities in the Consolidated Statements of Operations. Debt securities During 2022, the Company invested $500 million in convertible debt securities of Wolfspeed, Inc. (“Wolfspeed”) as part of a strategic partnership with Wolfspeed. The Company elected to classify the debt security as trading and remeasured the investment quarterly using fair value in accordance with ASC Topic 320, “Investments.” In 2023, the investment in Wolfspeed was disposed and the Company recorded a loss in Unrealized and realized loss on equity and debt securities in the Consolidated Statements of Operations. Prior to the disposition, the changes in fair value were recorded in Unrealized and realized loss on equity and debt securities in the Consolidated Statements of Operations.
Business Combinations	Business combinations In accordance with ASC Topic 805, “Business Combinations,” acquisitions are recorded using the acquisition method of accounting. The Company includes the operating results of acquired entities from their respective dates of acquisition. The Company recognizes and measures the identifiable assets acquired, liabilities assumed, and any non-controlling interest at the acquisition date fair value. Various valuation techniques are used to determine the fair value of intangible assets, with the primary techniques being forms of the income approach, specifically the relief-from-royalty and multi-period excess earnings valuation methods. Under these valuation approaches, the Company is required to make estimates and assumptions from a market participant perspective that may include revenue growth rates, estimated earnings, royalty rates, obsolescence factors, contributory asset charges, customer attrition and discount rates. The excess, if any, of total consideration transferred in a business combination over the fair value of identifiable assets acquired, liabilities assumed and any non-controlling interest is recognized as goodwill. Costs incurred as a result of a business combination other than costs related to the issuance of debt or equity securities are recorded in the period the costs are incurred. During the measurement period, which may be up to one year from the acquisition date, the Company may record adjustments to assets acquired and liabilities assumed with the corresponding offset to goodwill.
Revenue recognition	Revenue recognition Revenue is recognized when performance obligations under the terms of a contract are satisfied, which generally occurs with the transfer of control of the products. For most products, transfer of control occurs upon shipment or delivery; however, a limited number of customer arrangements for highly customized products with no alternative use provide the Company with the right to payment during the production process. As a result, for these limited arrangements, revenue is recognized as goods are produced and control transfers to the customer using the input cost-to-cost method. Revenue is measured at the amount of consideration the Company expects to receive in exchange for transferring the goods. Although the Company may enter into long-term supply arrangements with its major customers, the prices and volumes are not fixed over the life of the arrangements, and a contract does not exist for purposes of applying ASC Topic 606, “Revenue from Contracts with Customers,” until volumes are contractually known. Sales incentives and allowances (including returns) are recognized as a reduction to revenue at the time of the related sale. The Company estimates the allowances based on an analysis of historical experience. Taxes assessed by a governmental authority collected by the Company concurrent with a specific revenue-producing transaction are excluded from net sales. Shipping and handling fees billed to customers are included in sales, while costs of shipping and handling are included in cost of sales. The Company has elected to apply the accounting policy election available under ASC Topic 606 and accounts for shipping and handling activities as a fulfillment cost. The Company has a limited number of arrangements with customers where the price paid by the customer is dependent on the volume of product purchased over the term of the arrangement. In other arrangements, the Company will provide a rebate to customers based on the volume of products purchased during the course of the arrangement. The Company estimates the volumes to be sold over the term of the arrangement and recognizes revenue based on the estimated amount of consideration to be received from these arrangements. The Company continually seeks business development opportunities and at times provides customer incentives for new program awards. The Company evaluates the underlying economics of each amount of consideration payable to a customer to determine the proper accounting by understanding the reasons for the payment, the rights and obligations resulting from the payment, the nature of the promise in the contract, and other relevant facts and circumstances. When the Company determines that the payments are incremental and incurred only if the new business is obtained and expects to recover these amounts from the customer over the term of the new business arrangement, the Company capitalizes these amounts. The Company recognizes a reduction to revenue as products that the upfront payments are related to are transferred to the customer, based on the total amount of products expected to be sold over the term of the arrangement (generally three to seven years). The Company evaluates the amounts capitalized each period end for recoverability and expenses any amounts that are no longer expected to be recovered over the term of the business arrangement.
Cost of sales	Cost of sales The Company includes materials, direct labor and manufacturing overhead within cost of sales. Manufacturing overhead is comprised of indirect materials, indirect labor, factory operating costs, warranty costs and other such costs associated with manufacturing products for sale.
Cash and cash equivalents and Restricted cash	Cash and cash equivalents Cash and cash equivalents are valued at fair market value. It is the Company's policy to classify all highly liquid investments with original maturities of three months or less as cash and cash equivalents. Cash and cash equivalents are maintained with several financial institutions. Deposits held with banks may exceed the amount of insurance provided on such deposits. Generally, these deposits may be redeemed upon demand and are maintained with financial institutions of reputable credit and, therefore, bear minimal risk. Restricted cash Restricted cash includes amounts designated for uses other than current operations and is legally restricted as to use or withdrawal. As of December 31, 2024 and 2023, the Company had no restricted cash.
Receivables, net and long-term receivables	Receivables, net and long-term receivables Accounts receivable and long-term receivables are stated at cost less an allowance for credit losses. An allowance for credit losses is recorded for amounts that may become uncollectible in the future. The allowance for credit losses is an estimate based on expected losses, current economic and market conditions, and a review of the current status of each customer’s accounts receivable.
Inventories, net	Inventories, net Inventory is measured using FIFO or average-cost methods at the lower of cost or net realizable value. As of December 31, 2023, and through the third quarter of 2024, approximately 14% of the Company’s inventories were accounted for under the LIFO method of accounting. During the fourth quarter of 2024, the Company changed the method of accounting for these remaining LIFO inventories to FIFO. Refer to the change in accounting method discussion above and Note 9, “Inventories, Net,” to the Consolidated Financial Statements for more information.
Pre-production costs related to long-term supply arrangements	Pre-production costs related to long-term supply arrangements Engineering, research and development and other design and development costs for products sold on long-term supply arrangements are expensed as incurred unless the Company has a contractual guarantee for reimbursement from the customer. Costs for molds, dies and other tools used to make products sold on long-term supply arrangements for which the Company has title to the assets are capitalized in property, plant and equipment and amortized to cost of sales over the shorter of the term of the arrangement or over the estimated useful lives of the assets, typically three to five years. Costs for molds, dies and other tools used to make products sold on long-term supply arrangements for which the Company has a contractual guarantee for lump sum reimbursement from the customer are capitalized in prepayments and other current assets.
Property, plant and equipment, net	Property, plant and equipment, net Property, plant and equipment is valued at cost less accumulated depreciation. Expenditures for maintenance, repairs and renewals of relatively minor items are generally charged to expense as incurred. Renewals of significant items are capitalized. Depreciation is generally computed on a straight-line basis over the estimated useful lives of the assets. Useful lives for buildings range from 15 to 40 years, and useful lives for machinery and equipment range from three to 12 years. For income tax purposes, accelerated methods of depreciation are generally used.
Impairment of long-lived assets, including definite-lived intangible assets	Impairment of long-lived assets, including definite-lived intangible assets The Company reviews the carrying value of its long-lived assets, whether held for use or disposal, including other amortizing intangible assets, when events and circumstances warrant such a review under ASC Topic 360, “Property, Plant and Equipment.” In assessing long-lived assets for an impairment loss, assets are grouped with other assets and liabilities at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. In assessing long-lived assets for impairment, management generally considers individual facilities to be the lowest level for which identifiable cash flows are largely independent. A recoverability review is performed using the undiscounted cash flows if there is a triggering event. If the undiscounted cash flow test for recoverability identifies a possible impairment, management will perform a fair value analysis. Management determines fair value under ASC Topic 820, “Fair Value Measurement,” using the appropriate valuation technique of market, income or cost approach. If the carrying value of a long-lived asset is considered impaired, an impairment charge is recorded for the amount by which the carrying value of the long-lived asset exceeds its fair value. Management believes that the estimates of future cash flows and fair value assumptions are reasonable; however, changes in assumptions underlying these estimates could affect the valuations. Significant judgments and estimates used by management when evaluating long-lived assets for impairment include (i) an assessment as to whether an adverse event or circumstance has triggered the need for an impairment review; (ii) undiscounted future cash flows generated by the asset; and (iii) fair valuation of the asset. During the year ended December 31, 2024, the Company recorded charges of $69 million related to certain property, plant and equipment at locations in the Company’s Battery & Charging Systems and PowerDrive Systems reporting segments. In the fourth quarter of 2024, the Company noted deterioration in the forecast of its PowerDrive Systems and Battery & Charging Systems businesses due to further decreases in demand for eProducts as compared to the Company’s expectations as a result of electric vehicle adoption volatility across different regions. This was viewed as a triggering event, and as a result, individual facilities were tested for recoverability. These impairment charges related to locations that failed a recoverability test or where management had initiated plans to liquidate certain assets. During the year ended December 31, 2023, the Company recorded charges of $29 million, primarily related to the write down of a customer incentive asset, a service and lease agreement termination and impairment of certain property, plant and equipment. During the year ended December 31, 2022, the Company recorded an impairment charge of $30 million to remove the AKASOL indefinite-lived trade name as the Company no longer plans to utilize this trade name in the business. The charges referenced above were recognized in Impairment charges within the Consolidated Statements of Operations.
Goodwill and other intangible assets	Goodwill and other intangible assets During the fourth quarter of each year, the Company tests goodwill for impairment by either performing a qualitative assessment or a quantitative analysis. In addition, the Company may test goodwill in between annual test dates if an event occurs or circumstances change that could indicate it is more-likely-than-not that the fair value of a reporting unit is below its carrying value. The qualitative assessment evaluates various events and circumstances, such as macroeconomic conditions, industry and market conditions, cost factors, relevant events and financial trends, that may impact a reporting unit's fair value. Using this qualitative assessment, the Company determines whether it is more-likely-than-not the reporting unit's fair value exceeds its carrying value. If it is determined that it is not more-likely-than-not the reporting unit's fair value exceeds the carrying value, or upon consideration of other factors, including recent acquisition, restructuring or disposal activity or to refresh the fair values, the Company performs a quantitative goodwill impairment analysis. The Company has definite-lived intangible assets related to patents and developed technology, customer relationships and trade names. The Company amortizes definite-lived intangible assets over their estimated useful lives. The Company also has intangible assets related to acquired trade names that are classified as indefinite-lived when there are no foreseeable limits on the periods of time over which they are expected to contribute cash flows. Costs to renew or extend the term of acquired intangible assets are recognized as expense as incurred. Similar to goodwill, the Company can elect to perform the impairment test for indefinite-lived intangibles other than goodwill (primarily trade names) using a qualitative analysis, considering similar factors as outlined in the goodwill discussion, to determine if it is more-likely-than-not that the fair value of the trade names is less than the respective carrying values. If the Company elects to perform or is required to perform a quantitative analysis, the test consists of a comparison of the fair value of the indefinite-lived intangible asset to the carrying value of the asset as of the impairment testing date. The Company estimates the fair value of indefinite-lived intangibles using the relief-from-royalty method, which it believes is an appropriate and widely used valuation technique for such assets. The fair value derived from the relief-from-royalty method is measured as the discounted cash flow savings realized from owning such trade names and not being required to pay a royalty for their use. During the year ended December 31, 2024, the Company recorded charges of $577 million primarily related to the goodwill at PowerDrive Systems and Battery & Charging Systems. These charges were recognized in Impairment charges within the Consolidated Statements of Operations. Refer to Note 12, “Goodwill and Other Intangibles,” to the Consolidated Financial Statements for more information.
Assets and liabilities held for sale	Assets and liabilities held for sale The Company classifies assets and liabilities (disposal groups) to be sold as held for sale in the period in which all of the following criteria are met: (1) management, having the authority to approve the action, commits to a plan to sell the disposal group; (2) the disposal group is available for immediate sale in its present condition subject only to terms that are usual and customary for sales of such disposal groups; (3) an active program to locate a buyer and other actions required to complete the plan to sell the disposal group have been initiated; (4) the sale of the disposal group is probable, and transfer of the disposal group is expected to qualify for recognition as a completed sale within one year, except if events or circumstances beyond the Company’s control extend the period of time required to sell the disposal group beyond one year; (5) the disposal group is being actively marketed for sale at a price that is reasonable in relation to its current fair value; and (6) actions required to complete the plan indicate that it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn. The Company initially measures a disposal group that is classified as held for sale at the lower of its carrying value or fair value less any costs to sell. Any loss resulting from this measurement is recognized in the period in which the held for sale criteria are met. Conversely, gains are not recognized on the sale of a disposal group until the date of sale. The Company assesses the fair value of a disposal group, less any costs to sell, each reporting period it remains classified as held for sale and reports any subsequent changes as an adjustment to the carrying value of the disposal group, as long as the new carrying value does not exceed the carrying value of the disposal group at the time it was initially classified as held for sale. Additionally, depreciation is not recorded during the period in which the long-lived assets, included in the disposal group, are classified as held for sale. Upon determining that a disposal group meets the criteria to be classified as held for sale, the Company reports the assets and liabilities of the disposal group, if material, in the line items assets held for sale and liabilities held for sale in the Consolidated Balance Sheets.
Product warranties	Product warranties The Company provides warranties on some, but not all, of its products. The warranty terms are typically from one to three years. Provisions for estimated expenses related to product warranty are made at the time products are sold. These estimates are established using historical information about the nature, frequency and average cost of warranty claim settlements as well as product manufacturing and industry developments and recoveries from third parties. Management actively studies trends of warranty claims and takes action to improve product quality and minimize warranty claims. Costs of product recalls, which may include the cost of the product being replaced as well as the customer’s cost of the recall, including labor to remove and replace the recalled part, are accrued as part of the Company’s warranty accrual at the time an obligation becomes probable and can be reasonably estimated. Management believes that the warranty accrual is appropriate; however, actual claims incurred could differ from the original estimates, requiring adjustments to the accrual. The product warranty accrual is allocated to current and non-current liabilities in the Consolidated Balance Sheets.
Other loss accruals and valuation allowances	Other loss accruals and valuation allowances The Company has numerous other loss exposures, such as customer claims, workers’ compensation claims, litigation and recoverability of certain assets. Establishing loss accruals or valuation allowances for these matters requires the use of estimates and judgment in regard to the risk exposure and ultimate realization. The Company estimates losses using consistent and appropriate methods; however, changes to its assumptions could materially affect the recorded accrued liabilities for loss or asset valuation allowances.
Environmental contingencies	Environmental contingencies The Company accounts for environmental costs in accordance with ASC Topic 450, “Contingencies.” Costs related to environmental assessments and remediation efforts at operating facilities are accrued when it is probable that a liability has been incurred and the amount of that liability can be reasonably estimated. Estimated costs are recorded at undiscounted amounts, based on experience and assessments and are regularly evaluated. The liabilities are recorded in Other current and Other non-current liabilities in the Company’s Consolidated Balance Sheets.
Government grants	Government grants The Company periodically receives government grants representing assistance provided by a government. These government grants are generally received in cash and typically provide reimbursement related to acquisition of property and equipment, product development or local governmental economic relief. The government grants are generally amortized using a systematic and rational method over the life of the grant. As of December 31, 2024, the Company recorded government grant related liabilities of $22 million in Other current liabilities and $53 million in Other non-current liabilities in the Company’s Consolidated Balance Sheet. During the year ended December 31, 2024, the Company recorded $41 million and $7 million of government grant-related credits in Selling, general and administrative expenses and Cost of sales, respectively, in the Company’s Consolidated Statement of Operations.
Derivative financial instruments	Derivative financial instruments The Company recognizes that certain normal business transactions and foreign currency operations generate risk. Examples of risks include exposure to foreign currency exchange rate risk related to transactions denominated in currencies other than the functional currency, changes in commodity costs and interest rates. It is the objective of the Company to assess the impact of these transaction risks and offer protection from selected risks through various methods, including financial derivatives. Virtually all derivative instruments held by the Company are designated as hedges, have high correlation with the underlying exposure and are highly effective in offsetting underlying price movements. Accordingly, gains and losses from changes in qualifying hedge fair values are matched with the underlying transactions. Hedge instruments are generally reported gross, with no right to offset, on the Consolidated Balance Sheets at their fair value based on quoted market prices for contracts with similar maturities. The Company does not engage in any derivative transactions for purposes other than hedging specific operational risks.
Foreign currency	Foreign currency The financial statements of foreign subsidiaries are translated to U.S. Dollars using the period-end exchange rate for assets and liabilities and an average exchange rate for each period for revenues, expenses and capital expenditures. The local currency is the functional currency for substantially all of the Company's foreign subsidiaries. Translation adjustments for foreign subsidiaries are recorded as a component of accumulated other comprehensive income (loss) in equity. The Company recognizes transaction gains and losses arising from fluctuations in currency exchange rates on transactions denominated in currencies other than the functional currency in earnings as incurred.
Postretirement defined benefits	Postretirement defined benefits The Company’s defined benefit pension and other postemployment benefit plans are accounted for in accordance with ASC Topic 715, “Compensation - Retirement Benefits.” Disability, early retirement and other postemployment benefits are accounted for in accordance with ASC Topic 712, “Compensation - Nonretirement Postemployment Benefits.” Pensions and other postemployment benefit costs and related liabilities and assets are dependent upon assumptions used in calculating such amounts. These assumptions include discount rates, expected returns on plan assets, health care cost trends, compensation and other factors. In accordance with GAAP, actual results that differ from the assumptions used are accumulated and amortized over future periods, and accordingly, generally affect recognized expense in future periods.
Restructuring	Restructuring Restructuring costs may occur when the Company takes action to exit or significantly curtail a part of its operations or implements a reorganization that affects the nature and focus of operations. A restructuring charge can consist of severance costs associated with reductions to the workforce, costs to terminate an operating lease or contract, professional fees and other costs incurred related to the implementation of restructuring activities. The Company generally records costs associated with voluntary separations at the time of employee acceptance. Costs for involuntary separation programs are recorded when management has approved the plan for separation, the employees are identified and aware of the benefits to which they are entitled and it is unlikely that the plan will change significantly. When a plan of separation requires approval by or consultation with the relevant labor organization or government, the costs are recorded upon agreement. Costs associated with benefits that are contingent on the employee continuing to provide service are expensed over the required service period.
Income taxes	Income taxes In accordance with ASC Topic 740, “Income Taxes,” the Company’s income tax expense is calculated based on expected income and statutory tax rates in the various jurisdictions in which the Company operates and requires the use of management’s estimates and judgments. Accounting for income taxes is complex, in part because the Company conducts business globally and, therefore, files income tax returns in numerous tax jurisdictions. Management judgment is required in determining the Company’s worldwide provision for income taxes and recording the related assets and liabilities, including accruals for unrecognized tax benefits and assessing the need for valuation allowances. The determination of accruals for unrecognized tax benefits includes the application of complex tax laws in a multitude of jurisdictions across the Company’s global operations. Management judgment is required in determining the gross unrecognized tax benefits’ related liabilities. In the ordinary course of the Company’s business, there are many transactions and calculations where the ultimate tax determination is less than certain. Accruals for unrecognized tax benefits are established when, despite the belief that tax positions are supportable, there remain certain positions that do not meet the minimum probability threshold, which is a tax position that is more-likely-than-not to be sustained upon examination by the applicable taxing authority. The Company records valuation allowances to reduce the carrying value of deferred tax assets to amounts that it expects are more-likely-than-not to be realized. The Company assesses existing deferred tax assets, net operating losses and tax credit carryforwards by jurisdiction and expectations of its ability to utilize these tax attributes through a review of past, current and estimated future taxable income and tax planning strategies.
New Accounting Pronouncements	New Accounting Pronouncements Recently Adopted Accounting Standards In November 2023, the FASB issued ASU No. 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures.” It requires incremental disclosures related to an entity’s reportable segments, including (i) significant segment expense categories and amounts for each reportable segment that are provided to the chief operating decision maker (“CODM”), (ii) an aggregate amount and description of other segment items included in each reported measure, (iii) all annual disclosures about a reportable segment’s profit or loss and assets required by Topic 280 to be disclosed in interim periods, (iv) the title and position of the individual or the name of the group identified as the CODM and (v) an explanation of how the CODM uses the reported measures of segment profit or loss to assess performance and allocate resources to the segment. The standard improves transparency by providing disaggregated expense information about an entity’s reportable segments. The standard does not change the definition of a segment, the method for determining segments or the criteria for aggregating operating segments into reportable segments. This guidance is effective for annual reporting periods beginning after December 15, 2023, and interim reporting periods beginning after December 15, 2024. The Company adopted this guidance retrospectively, providing the additional disclosures as required. Refer to Note 24, “Reportable Segments and Related Information” to the Consolidated Financial Statements for more information. Accounting Standards Not Yet Adopted In December 2023, the FASB issued ASU No. 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures.” It requires entities to disaggregate information related to the effective tax rate reconciliation and income taxes paid. The standard improves transparency by providing more detailed income tax disclosures that would be useful in making capital allocation decisions. This guidance is effective for annual reporting periods beginning after December 15, 2024. The Company does not expect this guidance to have a material impact on its Consolidated Financial Statements. In November 2024, the FASB issued ASU No. 2024-03, “Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses.” It requires entities to disclose, in the notes to financial statements, specified information related to certain costs and expenses disaggregated by type. The standard improves transparency by providing more detailed information about the components of costs and expenses that would enable investors to better understand the major components of an entity’s income statement by referencing specific disclosures in the notes to financial statements. This guidance is effective for annual reporting periods beginning after December 15, 2026. The Company does not expect this guidance to have a material impact on its Consolidated Financial Statements.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)

12 Months Ended

Dec. 31, 2024

Basis of presentation Certain prior period amounts have been reclassified to conform to current period presentation. Additionally, in the year ended December 31, 2024, the Company recognized a $19 million increase in Net earnings attributable to BorgWarner Inc. in the Consolidated Statement of Operations for the correction of misstatements related to certain accruals, of which $12 million related to 2023 (the remainder relates to periods prior to 2023). The Company has evaluated the effect of these out-of-period adjustments for the current reporting period, as well as on the previous interim and annual periods in which they should have been recognized, and concluded that these adjustments are not material to any of the periods affected.

As discussed in the Introduction above, as a result of the Spin-Off, the historical results of operations and the financial position of PHINIA for periods prior to the Spin-Off are presented as discontinued operations in these Consolidated Financial Statements. Refer to Note 26, “Discontinued Operations,” to the Consolidated Financial Statements for more information.

The Company’s Consolidated Financial Statements reflect the results of acquisitions following the date of the respective acquisition. Refer to Note 2, “Acquisitions and Dispositions,” to the Consolidated Financial Statements for more information.

Use of estimates

Use of estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the accompanying notes, as well as the amounts of revenues and expenses reported during the periods covered by these financial statements and accompanying notes. Actual results could differ from those estimates.

Principles of Consolidation

Principles of consolidation The Consolidated Financial Statements include all majority-owned subsidiaries in which the Company has a controlling financial interest. All inter-company balances and transactions have been eliminated in consolidation.

Change in accounting method

Change in accounting method Historically, certain of the Company’s U.S. inventories (approximately 14% of the Company’s total inventories at December 31, 2023) were accounted for under the last-in, first-out (“LIFO”) method of accounting. During the fourth quarter of 2024, the Company changed the inventory valuation method for those locations from LIFO to the first-in, first-out (“FIFO”) method. FIFO was deemed a preferable method as it better aligns with the accounting practices of the Company’s peers, it more accurately reflects the current value and physical flow of inventory, and it harmonizes the accounting method for the majority of inventories across the Company. Retroactive application of the change to prior periods did not have a material impact on any prior periods’ Consolidated Financial Statements, and therefore the Company recognized the cumulative effect of the change in the fourth quarter of 2024 as a reduction in Cost of sales of $29 million in the Consolidated Statements of Operations, which resulted in an increase in income before taxes of $29 million ($22 million after tax) for the three months ended December 31, 2024 with a corresponding increase in Inventories, net within the Consolidated Balance Sheet as of December 31, 2024.

Joint ventures and equity securities

Joint ventures and equity securities The Company has investments in three unconsolidated joint ventures, NSK-Warner K.K. , Turbo Energy Private Limited, and Fast Warner Intelligent Control Systems Co., Ltd of which the Company owns 50%, 32.6%, and 49.0%, respectively. These joint ventures are non-controlled affiliates in which the Company exercises significant influence but does not have a controlling financial interest and, therefore, are accounted for under the equity method. Generally, under the equity method, the Company’s original investments in these joint ventures are recorded at cost and subsequently adjusted by the Company’s share of equity in income or losses. The Company monitors its

equity method investments for indicators of other-than-temporary declines in fair value on an ongoing basis. If such a decline has occurred, an impairment charge is recorded, which is measured as the difference between the carrying value and the estimated fair value. The Company’s investment in these non-controlled affiliates is included within Investments and long-term receivables in the Consolidated Balance Sheets. The Company’s share of equity in income or losses is included in Equity in affiliates’ earnings, net of tax in the Consolidated Statements of Operations.

The Company also has certain investments for which it does not have the ability to exercise significant influence (generally when ownership interest is less than 20%). The Company’s investment in these equity securities is included within Investments and long-term receivables in the Consolidated Balance Sheet. Refer to Note 10, “Other Current and Non-Current Assets,” to the Consolidated Financial Statements for more information.

Interests in privately held companies that do not have readily determinable fair values are accounted for using the measurement alternative under ASC Topic 321, “Investments - Equity Securities,” which includes monitoring on an ongoing basis for indicators of impairments or upward adjustments. These equity securities are measured at cost less impairments, adjusted for observable price changes in orderly transactions for the identical or similar investment of the same issuer. If the Company determines that an indicator of impairment or upward adjustment is present, an adjustment is recorded, which is measured as the difference between carrying value and estimated fair value. Estimated fair value is generally determined using an income approach on discounted cash flows or negotiated transaction values.

Equity securities that have readily determinable fair values are measured at fair value. Equity securities that do not have a readily determinable fair value and which provide a net asset value (“NAV”) or its equivalent, are valued using NAV as a practical expedient. Changes in fair value and NAV are recorded in Unrealized and realized loss on equity and debt securities in the Consolidated Statements of Operations.

Debt securities During 2022, the Company invested $500 million in convertible debt securities of Wolfspeed, Inc. (“Wolfspeed”) as part of a strategic partnership with Wolfspeed. The Company elected to classify the debt security as trading and remeasured the investment quarterly using fair value in accordance with ASC Topic 320, “Investments.” In 2023, the investment in Wolfspeed was disposed and the Company recorded a loss in Unrealized and realized loss on equity and debt securities in the Consolidated Statements of Operations. Prior to the disposition, the changes in fair value were recorded in Unrealized and realized loss on equity and debt securities in the Consolidated Statements of Operations.

Business Combinations

Business combinations In accordance with ASC Topic 805, “Business Combinations,” acquisitions are recorded using the acquisition method of accounting. The Company includes the operating results of acquired entities from their respective dates of acquisition. The Company recognizes and measures the identifiable assets acquired, liabilities assumed, and any non-controlling interest at the acquisition date fair value. Various valuation techniques are used to determine the fair value of intangible assets, with the primary techniques being forms of the income approach, specifically the relief-from-royalty and multi-period excess earnings valuation methods. Under these valuation approaches, the Company is required to make estimates and assumptions from a market participant perspective that may include revenue growth rates, estimated earnings, royalty rates, obsolescence factors, contributory asset charges, customer attrition and discount rates. The excess, if any, of total consideration transferred in a business combination over the fair value of identifiable assets acquired, liabilities assumed and any non-controlling interest is recognized as goodwill. Costs incurred as a result of a business combination other than costs related to the issuance of debt or equity securities are recorded in the period the costs are incurred. During the measurement period, which may be up to one year from the acquisition date, the Company may record adjustments to assets acquired and liabilities assumed with the corresponding offset to goodwill.

Revenue recognition

Revenue recognition Revenue is recognized when performance obligations under the terms of a contract are satisfied, which generally occurs with the transfer of control of the products. For most

products, transfer of control occurs upon shipment or delivery; however, a limited number of customer arrangements for highly customized products with no alternative use provide the Company with the right to payment during the production process. As a result, for these limited arrangements, revenue is recognized as goods are produced and control transfers to the customer using the input cost-to-cost method. Revenue is measured at the amount of consideration the Company expects to receive in exchange for transferring the goods. Although the Company may enter into long-term supply arrangements with its major customers, the prices and volumes are not fixed over the life of the arrangements, and a contract does not exist for purposes of applying ASC Topic 606, “Revenue from Contracts with Customers,” until volumes are contractually known.

Sales incentives and allowances (including returns) are recognized as a reduction to revenue at the time of the related sale. The Company estimates the allowances based on an analysis of historical experience. Taxes assessed by a governmental authority collected by the Company concurrent with a specific revenue-producing transaction are excluded from net sales. Shipping and handling fees billed to customers are included in sales, while costs of shipping and handling are included in cost of sales. The Company has elected to apply the accounting policy election available under ASC Topic 606 and accounts for shipping and handling activities as a fulfillment cost.

The Company has a limited number of arrangements with customers where the price paid by the customer is dependent on the volume of product purchased over the term of the arrangement. In other arrangements, the Company will provide a rebate to customers based on the volume of products purchased during the course of the arrangement. The Company estimates the volumes to be sold over the term of the arrangement and recognizes revenue based on the estimated amount of consideration to be received from these arrangements.

The Company continually seeks business development opportunities and at times provides customer incentives for new program awards. The Company evaluates the underlying economics of each amount of consideration payable to a customer to determine the proper accounting by understanding the reasons for the payment, the rights and obligations resulting from the payment, the nature of the promise in the contract, and other relevant facts and circumstances. When the Company determines that the payments are incremental and incurred only if the new business is obtained and expects to recover these amounts from the customer over the term of the new business arrangement, the Company capitalizes these amounts. The Company recognizes a reduction to revenue as products that the upfront payments are related to are transferred to the customer, based on the total amount of products expected to be sold over the term of the arrangement (generally three to seven years). The Company evaluates the amounts capitalized each period end for recoverability and expenses any amounts that are no longer expected to be recovered over the term of the business arrangement.

Cost of sales

Cost of sales The Company includes materials, direct labor and manufacturing overhead within cost of sales. Manufacturing overhead is comprised of indirect materials, indirect labor, factory operating costs, warranty costs and other such costs associated with manufacturing products for sale.

Cash and cash equivalents and Restricted cash

Cash and cash equivalents Cash and cash equivalents are valued at fair market value. It is the Company's policy to classify all highly liquid investments with original maturities of three months or less as cash and cash equivalents. Cash and cash equivalents are maintained with several financial institutions. Deposits held with banks may exceed the amount of insurance provided on such deposits. Generally, these deposits may be redeemed upon demand and are maintained with financial institutions of reputable credit and, therefore, bear minimal risk.

Restricted cash Restricted cash includes amounts designated for uses other than current operations and is legally restricted as to use or withdrawal. As of December 31, 2024 and 2023, the Company had no restricted cash.

Receivables, net and long-term receivables

Receivables, net and long-term receivables Accounts receivable and long-term receivables are stated at cost less an allowance for credit losses. An allowance for credit losses is recorded for amounts that may become uncollectible in the future. The allowance for credit losses is an estimate based on expected losses, current economic and market conditions, and a review of the current status of each customer’s accounts receivable.

Inventories, net

Inventories, net Inventory is measured using FIFO or average-cost methods at the lower of cost or net realizable value. As of December 31, 2023, and through the third quarter of 2024, approximately 14% of the Company’s inventories were accounted for under the LIFO method of accounting. During the fourth quarter of 2024, the Company changed the method of accounting for these remaining LIFO inventories to FIFO. Refer to the change in accounting method discussion above and Note 9, “Inventories, Net,” to the Consolidated Financial Statements for more information.

Pre-production costs related to long-term supply arrangements

Pre-production costs related to long-term supply arrangements Engineering, research and development and other design and development costs for products sold on long-term supply arrangements are expensed as incurred unless the Company has a contractual guarantee for reimbursement from the customer. Costs for molds, dies and other tools used to make products sold on long-term supply arrangements for which the Company has title to the assets are capitalized in property, plant and equipment and amortized to cost of sales over the shorter of the term of the arrangement or over the estimated useful lives of the assets, typically three to five years. Costs for molds, dies and other tools used to make products sold on long-term supply arrangements for which the Company has a contractual guarantee for lump sum reimbursement from the customer are capitalized in prepayments and other current assets.

Property, plant and equipment, net

Property, plant and equipment, net Property, plant and equipment is valued at cost less accumulated depreciation. Expenditures for maintenance, repairs and renewals of relatively minor items are generally charged to expense as incurred. Renewals of significant items are capitalized. Depreciation is generally computed on a straight-line basis over the estimated useful lives of the assets. Useful lives for buildings range from 15 to 40 years, and useful lives for machinery and equipment range from three to 12 years. For income tax purposes, accelerated methods of depreciation are generally used.

Impairment of long-lived assets, including definite-lived intangible assets

Impairment of long-lived assets, including definite-lived intangible assets The Company reviews the carrying value of its long-lived assets, whether held for use or disposal, including other amortizing intangible assets, when events and circumstances warrant such a review under ASC Topic 360, “Property, Plant and Equipment.” In assessing long-lived assets for an impairment loss, assets are grouped with other assets and liabilities at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. In assessing long-lived assets for impairment, management generally considers individual facilities to be the lowest level for which identifiable cash flows are largely independent. A recoverability review is performed using the undiscounted cash flows if there is a triggering event. If the undiscounted cash flow test for recoverability identifies a possible impairment, management will perform a fair value analysis. Management determines fair value under ASC Topic 820, “Fair Value Measurement,” using the appropriate valuation technique of market, income or cost approach. If the carrying value of a long-lived asset is considered impaired, an impairment charge is recorded for the amount by which the carrying value of the long-lived asset exceeds its fair value.

Management believes that the estimates of future cash flows and fair value assumptions are reasonable; however, changes in assumptions underlying these estimates could affect the valuations. Significant

judgments and estimates used by management when evaluating long-lived assets for impairment include (i) an assessment as to whether an adverse event or circumstance has triggered the need for an impairment review; (ii) undiscounted future cash flows generated by the asset; and (iii) fair valuation of the asset.

During the year ended December 31, 2024, the Company recorded charges of $69 million related to certain property, plant and equipment at locations in the Company’s Battery & Charging Systems and PowerDrive Systems reporting segments. In the fourth quarter of 2024, the Company noted deterioration in the forecast of its PowerDrive Systems and Battery & Charging Systems businesses due to further decreases in demand for eProducts as compared to the Company’s expectations as a result of electric vehicle adoption volatility across different regions. This was viewed as a triggering event, and as a result, individual facilities were tested for recoverability. These impairment charges related to locations that failed a recoverability test or where management had initiated plans to liquidate certain assets.

During the year ended December 31, 2023, the Company recorded charges of $29 million, primarily related to the write down of a customer incentive asset, a service and lease agreement termination and impairment of certain property, plant and equipment. During the year ended December 31, 2022, the Company recorded an impairment charge of $30 million to remove the AKASOL indefinite-lived trade name as the Company no longer plans to utilize this trade name in the business.

The charges referenced above were recognized in Impairment charges within the Consolidated Statements of Operations.

Goodwill and other intangible assets

Goodwill and other intangible assets During the fourth quarter of each year, the Company tests goodwill for impairment by either performing a qualitative assessment or a quantitative analysis. In addition, the Company may test goodwill in between annual test dates if an event occurs or circumstances change that could indicate it is more-likely-than-not that the fair value of a reporting unit is below its carrying value.

The qualitative assessment evaluates various events and circumstances, such as macroeconomic conditions, industry and market conditions, cost factors, relevant events and financial trends, that may impact a reporting unit's fair value. Using this qualitative assessment, the Company determines whether it is more-likely-than-not the reporting unit's fair value exceeds its carrying value. If it is determined that it is not more-likely-than-not the reporting unit's fair value exceeds the carrying value, or upon consideration of other factors, including recent acquisition, restructuring or disposal activity or to refresh the fair values, the Company performs a quantitative goodwill impairment analysis.

The Company has definite-lived intangible assets related to patents and developed technology, customer relationships and trade names. The Company amortizes definite-lived intangible assets over their estimated useful lives. The Company also has intangible assets related to acquired trade names that are classified as indefinite-lived when there are no foreseeable limits on the periods of time over which they are expected to contribute cash flows. Costs to renew or extend the term of acquired intangible assets are recognized as expense as incurred.

Similar to goodwill, the Company can elect to perform the impairment test for indefinite-lived intangibles other than goodwill (primarily trade names) using a qualitative analysis, considering similar factors as outlined in the goodwill discussion, to determine if it is more-likely-than-not that the fair value of the trade names is less than the respective carrying values. If the Company elects to perform or is required to perform a quantitative analysis, the test consists of a comparison of the fair value of the indefinite-lived intangible asset to the carrying value of the asset as of the impairment testing date. The Company estimates the fair value of indefinite-lived intangibles using the relief-from-royalty method, which it believes is an appropriate and widely used valuation technique for such assets. The fair value derived from the relief-from-royalty method is measured as the discounted cash flow savings realized from owning such trade names and not being required to pay a royalty for their use.

During the year ended December 31, 2024, the Company recorded charges of $577 million primarily related to the goodwill at PowerDrive Systems and Battery & Charging Systems. These charges were recognized in Impairment charges within the Consolidated Statements of Operations.

Refer to Note 12, “Goodwill and Other Intangibles,” to the Consolidated Financial Statements for more information.

Assets and liabilities held for sale

Assets and liabilities held for sale The Company classifies assets and liabilities (disposal groups) to be sold as held for sale in the period in which all of the following criteria are met: (1) management, having the authority to approve the action, commits to a plan to sell the disposal group; (2) the disposal group is available for immediate sale in its present condition subject only to terms that are usual and customary for sales of such disposal groups; (3) an active program to locate a buyer and other actions required to complete the plan to sell the disposal group have been initiated; (4) the sale of the disposal group is probable, and transfer of the disposal group is expected to qualify for recognition as a completed sale within one year, except if events or circumstances beyond the Company’s control extend the period of time required to sell the disposal group beyond one year; (5) the disposal group is being actively marketed for sale at a price that is reasonable in relation to its current fair value; and (6) actions required to complete the plan indicate that it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn.

The Company initially measures a disposal group that is classified as held for sale at the lower of its carrying value or fair value less any costs to sell. Any loss resulting from this measurement is recognized in the period in which the held for sale criteria are met. Conversely, gains are not recognized on the sale of a disposal group until the date of sale. The Company assesses the fair value of a disposal group, less any costs to sell, each reporting period it remains classified as held for sale and reports any subsequent changes as an adjustment to the carrying value of the disposal group, as long as the new carrying value does not exceed the carrying value of the disposal group at the time it was initially classified as held for sale. Additionally, depreciation is not recorded during the period in which the long-lived assets, included in the disposal group, are classified as held for sale.

Upon determining that a disposal group meets the criteria to be classified as held for sale, the Company reports the assets and liabilities of the disposal group, if material, in the line items assets held for sale and liabilities held for sale in the Consolidated Balance Sheets.

Product warranties

Product warranties The Company provides warranties on some, but not all, of its products. The warranty terms are typically from one to three years. Provisions for estimated expenses related to product warranty are made at the time products are sold. These estimates are established using historical information about the nature, frequency and average cost of warranty claim settlements as well as product manufacturing and industry developments and recoveries from third parties. Management actively studies trends of warranty claims and takes action to improve product quality and minimize warranty claims. Costs of product recalls, which may include the cost of the product being replaced as well as the customer’s cost of the recall, including labor to remove and replace the recalled part, are accrued as part of the Company’s warranty accrual at the time an obligation becomes probable and can be reasonably estimated. Management believes that the warranty accrual is appropriate; however, actual claims incurred could differ from the original estimates, requiring adjustments to the accrual. The product warranty accrual is allocated to current and non-current liabilities in the Consolidated Balance Sheets.

Other loss accruals and valuation allowances

Other loss accruals and valuation allowances The Company has numerous other loss exposures, such as customer claims, workers’ compensation claims, litigation and recoverability of certain assets. Establishing loss accruals or valuation allowances for these matters requires the use of estimates and judgment in regard to the risk exposure and ultimate realization. The Company estimates losses using consistent and appropriate methods; however, changes to its assumptions could materially affect the recorded accrued liabilities for loss or asset valuation allowances.

Environmental contingencies

Environmental contingencies The Company accounts for environmental costs in accordance with ASC Topic 450, “Contingencies.” Costs related to environmental assessments and remediation efforts at operating facilities are accrued when it is probable that a liability has been incurred and the amount of that liability can be reasonably estimated. Estimated costs are recorded at undiscounted amounts, based on experience and assessments and are regularly evaluated. The liabilities are recorded in Other current and Other non-current liabilities in the Company’s Consolidated Balance Sheets.

Government grants

Government grants The Company periodically receives government grants representing assistance provided by a government. These government grants are generally received in cash and typically provide reimbursement related to acquisition of property and equipment, product development or local governmental economic relief. The government grants are generally amortized using a systematic and rational method over the life of the grant. As of December 31, 2024, the Company recorded government grant related liabilities of $22 million in Other current liabilities and $53 million in Other non-current liabilities in the Company’s Consolidated Balance Sheet. During the year ended December 31, 2024, the Company recorded $41 million and $7 million of government grant-related credits in Selling, general and administrative expenses and Cost of sales, respectively, in the Company’s Consolidated Statement of Operations.

Derivative financial instruments

Derivative financial instruments The Company recognizes that certain normal business transactions and foreign currency operations generate risk. Examples of risks include exposure to foreign currency exchange rate risk related to transactions denominated in currencies other than the functional currency, changes in commodity costs and interest rates. It is the objective of the Company to assess the impact of these transaction risks and offer protection from selected risks through various methods, including financial derivatives. Virtually all derivative instruments held by the Company are designated as hedges, have high correlation with the underlying exposure and are highly effective in offsetting underlying price movements. Accordingly, gains and losses from changes in qualifying hedge fair values are matched with the underlying transactions. Hedge instruments are generally reported gross, with no right to offset, on the Consolidated Balance Sheets at their fair value based on quoted market prices for contracts with similar maturities. The Company does not engage in any derivative transactions for purposes other than hedging specific operational risks.

Foreign currency

Foreign currency The financial statements of foreign subsidiaries are translated to U.S. Dollars using the period-end exchange rate for assets and liabilities and an average exchange rate for each period for revenues, expenses and capital expenditures. The local currency is the functional currency for substantially all of the Company's foreign subsidiaries. Translation adjustments for foreign subsidiaries are recorded as a component of accumulated other comprehensive income (loss) in equity. The Company recognizes transaction gains and losses arising from fluctuations in currency exchange rates on transactions denominated in currencies other than the functional currency in earnings as incurred.

Postretirement defined benefits

Postretirement defined benefits The Company’s defined benefit pension and other postemployment benefit plans are accounted for in accordance with ASC Topic 715, “Compensation - Retirement Benefits.” Disability, early retirement and other postemployment benefits are accounted for in accordance with ASC Topic 712, “Compensation - Nonretirement Postemployment Benefits.”

Pensions and other postemployment benefit costs and related liabilities and assets are dependent upon assumptions used in calculating such amounts. These assumptions include discount rates, expected returns on plan assets, health care cost trends, compensation and other factors. In accordance with GAAP, actual results that differ from the assumptions used are accumulated and amortized over future periods, and accordingly, generally affect recognized expense in future periods.

Restructuring

Restructuring Restructuring costs may occur when the Company takes action to exit or significantly curtail a part of its operations or implements a reorganization that affects the nature and focus of operations. A restructuring charge can consist of severance costs associated with reductions to the workforce, costs to terminate an operating lease or contract, professional fees and other costs incurred related to the implementation of restructuring activities.

The Company generally records costs associated with voluntary separations at the time of employee acceptance. Costs for involuntary separation programs are recorded when management has approved the plan for separation, the employees are identified and aware of the benefits to which they are entitled and it is unlikely that the plan will change significantly. When a plan of separation requires approval by or consultation with the relevant labor organization or government, the costs are recorded upon agreement. Costs associated with benefits that are contingent on the employee continuing to provide service are expensed over the required service period.

Income taxes

Income taxes In accordance with ASC Topic 740, “Income Taxes,” the Company’s income tax expense is calculated based on expected income and statutory tax rates in the various jurisdictions in which the Company operates and requires the use of management’s estimates and judgments. Accounting for income taxes is complex, in part because the Company conducts business globally and, therefore, files income tax returns in numerous tax jurisdictions. Management judgment is required in determining the Company’s worldwide provision for income taxes and recording the related assets and liabilities, including accruals for unrecognized tax benefits and assessing the need for valuation allowances.

The determination of accruals for unrecognized tax benefits includes the application of complex tax laws in a multitude of jurisdictions across the Company’s global operations. Management judgment is required in determining the gross unrecognized tax benefits’ related liabilities. In the ordinary course of the Company’s business, there are many transactions and calculations where the ultimate tax determination is less than certain. Accruals for unrecognized tax benefits are established when, despite the belief that tax positions are supportable, there remain certain positions that do not meet the minimum probability threshold, which is a tax position that is more-likely-than-not to be sustained upon examination by the applicable taxing authority.

The Company records valuation allowances to reduce the carrying value of deferred tax assets to amounts that it expects are more-likely-than-not to be realized. The Company assesses existing deferred tax assets, net operating losses and tax credit carryforwards by jurisdiction and expectations of its ability to utilize these tax attributes through a review of past, current and estimated future taxable income and tax planning strategies.

New Accounting Pronouncements

Recently Adopted Accounting Standards

In November 2023, the FASB issued ASU No. 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures.” It requires incremental disclosures related to an entity’s reportable segments, including (i) significant segment expense categories and amounts for each reportable segment that are provided to the chief operating decision maker (“CODM”), (ii) an aggregate amount and description of other segment items included in each reported measure, (iii) all annual disclosures about a reportable segment’s profit or loss and assets required by Topic 280 to be disclosed in interim periods, (iv) the title and position of the individual or the name of the group identified as the CODM and (v) an explanation of how the CODM uses the reported measures of segment profit or loss to assess performance and allocate resources to the segment. The standard improves transparency by providing disaggregated expense information about an entity’s reportable segments. The standard does not change the definition of a segment, the method for determining segments or the criteria for aggregating operating segments into reportable segments. This guidance is effective for annual reporting periods beginning after December 15, 2023, and interim reporting periods beginning after December 15, 2024. The Company adopted this guidance retrospectively, providing the additional disclosures as required. Refer to Note 24, “Reportable Segments and Related Information” to the Consolidated Financial Statements for more information.

Accounting Standards Not Yet Adopted

In December 2023, the FASB issued ASU No. 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures.” It requires entities to disaggregate information related to the effective tax rate reconciliation and income taxes paid. The standard improves transparency by providing more detailed income tax disclosures that would be useful in making capital allocation decisions. This guidance is effective for annual reporting periods beginning after December 15, 2024. The Company does not expect this guidance to have a material impact on its Consolidated Financial Statements.

In November 2024, the FASB issued ASU No. 2024-03, “Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses.” It requires entities to disclose, in the notes to financial statements, specified information related to certain costs and expenses disaggregated by type. The standard improves transparency by providing more detailed information about the components of costs and expenses that would enable investors to better understand the major components of an entity’s income statement by referencing specific disclosures in the notes to financial statements. This guidance is effective for annual reporting periods beginning after December 15, 2026. The Company does not expect this guidance to have a material impact on its Consolidated Financial Statements.
