| Impairment or Disposal of Long-Lived Assets, Policy [Policy Text Block] | Valuation of long-lived assets —The carrying value of long-lived assets held for use, including definite-lived intangible assets, is periodically evaluated when events or circumstances warrant such a review. The carrying value of a long-lived asset held for use is considered impaired when the anticipated separately identifiable undiscounted cash flows from the asset are less than the carrying value of the asset. In that event, a loss is recognized based on the amount by which the carrying value exceeds the estimated fair value of the long-lived asset. Impairment losses on long-lived assets held for sale are recognized if the carrying value of the asset is in excess of the asset’s estimated fair value, reduced for the cost to dispose of the asset. Fair value of long-lived assets is determined primarily using the anticipated cash flows discounted at a rate commensurate with the risk involved (an income approach), and in certain situations the Company’s review of appraisals (a market approach). Refer to Note 6. Property, Net for additional information. |
| Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block] | GENERAL On December 4, 2017 , Delphi Technologies PLC became an independent publicly-traded company, formed under the laws of Jersey, as a result of the separation of the Powertrain Systems segment, which included the aftermarket operations, from Delphi Automotive PLC (the “Former Parent”). The separation was completed in the form of a pro-rata distribution to the Former Parent shareholders of record on November 22, 2017 of 100% of the outstanding ordinary shares of Delphi Technologies PLC (the “Separation”). Following the Separation, Delphi Automotive PLC changed its name to Aptiv PLC (“Aptiv”). Delphi Technologies’ ordinary shares began trading on the New York Stock Exchange under the ticker symbol “DLPH” on December 5, 2017 (references hereinafter to “Delphi Technologies,” “we,” “us,” “our” or the “Company” refer to Delphi Technologies PLC and include the results of the Former Parent’s Powertrain Systems segment). Nature of Operations Delphi Technologies is a leader in the development, design and manufacture of integrated powertrain technologies that optimize engine performance, increase vehicle efficiency, reduce emissions, improve driving performance, and support increasing electrification of vehicles. The Company is a global supplier to original equipment manufacturers (“OEMs”) seeking to manufacture vehicles that meet and exceed increasingly stringent global regulatory requirements and satisfy consumer demands for an enhanced user experience. We provide advanced fuel injection systems, actuators, valvetrain products, sensors, electronic control modules and power electronics technologies. Additionally, the Company offers a full spectrum of aftermarket products serving a global customer base. Our comprehensive portfolio of advanced technologies and solutions for all propulsion systems are sold to global OEMs of both light vehicles (passenger cars, trucks, vans and sport-utility vehicles) and commercial vehicles (light-duty, medium-duty and heavy-duty trucks, commercial vans, buses and off-highway vehicles). The Aftermarket segment also remanufactures and sells our products to leading aftermarket companies, including independent retailers and wholesale distributors. We supply a wide range of aftermarket products and services covering the fuel injection, electronics and engine management, maintenance, and test equipment and vehicle diagnostics categories. We also add aftermarket know-how in category management, logistics, training, marketing and other dedicated services to provide a full range of aftermarket solutions throughout a vehicles’ lifecycle. Basis of Presentation Prior to the Separation on December 4, 2017 , the historical financial statements of Delphi Technologies were prepared on a stand-alone combined basis and were derived from the Former Parent’s consolidated financial statements and accounting records. These financial statements were prepared as if the Powertrain Systems segment, which historically included Aftermarket, of the Former Parent had been part of Delphi Technologies for all periods presented. Accordingly, for periods prior to December 4, 2017 , our financial statements are presented on a combined basis and for the periods subsequent to December 4, 2017 , are presented on a consolidated basis (all periods hereinafter are referred to as “consolidated financial statements”). The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). At the time of the Separation, we used available information to develop our best estimates for certain assets and liabilities related to the Separation. In certain instances, final determination of the Separation-related balances was made in subsequent periods, and any adjustments, if necessary, were recorded to shareholders’ equity when determined. The Company’s historical financial statements for the period prior to December 4, 2017 reflect an allocation of expenses related to certain corporate functions of the Former Parent, including senior management, legal, human resources, finance and accounting, treasury, information technology services and support, cash management, payroll processing, pension and benefit administration and other shared services. These costs were allocated using methodologies that management believes were reasonable for the item being allocated. Allocation methodologies included direct usage when identifiable, as well as the Company’s relative share of revenues, headcount or functional spend as a percentage of the total. However, the allocations are not indicative of the actual expenses that would have been incurred had Delphi Technologies operated as a stand-alone publicly-traded company for the periods presented. Accordingly, the historical financial information presented for periods prior to December 4, 2017 may not be indicative of the results of operations or cash flows that would have been achieved if Delphi Technologies had been a stand-alone publicly-traded company during the periods shown or of the Company’s performance for periods subsequent to December 4, 2017 . Related party allocations are further described in Note 3. Related Party Transactions. Prior to the Separation, transfers of cash to and from the Former Parent were reflected as a component of the Former Parent’s net investment in the consolidated financial statements. Cash and cash equivalents held by the Former Parent were not attributable to Delphi Technologies for any of the prior periods presented. Only cash amounts specifically attributable to Delphi Technologies are reflected in the accompanying consolidated financial statements. Prior to December 4, 2017 , all intercompany transactions between the Company and the Former Parent were considered to be effectively settled in the historical financial statements at the time the transactions were recorded. As a result, the total net effect of the settlement of these intercompany transactions was reflected in the consolidated statements of cash flows as a financing activity. In connection with the Separation, the Former Parent’s net investment was reclassified within shareholders’ equity and allocated between ordinary shares and additional paid-in capital based on the number of our ordinary shares outstanding at the distribution date. |

Related party allocations are further described in Note 3. Related Party Transactions. Prior to the Separation, transfers of cash to and from the Former Parent were reflected as a component of the Former Parent’s net investment in the consolidated financial statements.

In connection with the Separation, the Former Parent’s net investment was reclassified within shareholders’ equity and allocated between ordinary shares and additional paid-in capital based on the number of our ordinary shares outstanding at the distribution date. |
| Principles of Consolidation | Principles of Consolidation —The consolidated financial statements as of and for the year ended December 31, 2019 include the accounts of Delphi Technologies’ subsidiaries in which the Company holds a controlling financial or management interest and variable interest entities of which Delphi Technologies has determined that it is the primary beneficiary. All significant intercompany transactions and balances between consolidated Delphi Technologies businesses have been eliminated. For periods prior to December 4, 2017 , transactions between the Company and the Former Parent have been included in the financial statements within Former Parent net investment. Prior to December 4, 2017 , expenses related to corporate allocations from the Former Parent to the Company were considered to be effectively settled for cash in the financial statements at the time the transaction was recorded. Prior to the Separation, transactions between the Company and the Former Parent’s other subsidiaries were classified as related party transactions within the consolidated financial statements. Delphi Technologies’ share of the earnings or losses of Delphi-TVS Diesel Systems Ltd (of which Delphi Technologies owns approximately 50% ), a non-controlled affiliate located in India over which the Company exercises significant influence, is included in the consolidated operating results of Delphi Technologies using the equity method of accounting. During the year ended December 31, 2015, Delphi Technologies made a $20 million investment in Tula Technology, Inc. (“Tula”), an engine control software company, over which the Company does not exert significant influence. During the year ended December 31, 2017, Delphi Technologies made an additional $1 million investment in Tula. During the year ended December 31, 2018, Delphi Technologies made a $7 million investment in PolyCharge America, Inc. (“PolyCharge”), a start-up established to commercialize a new capacitor technology, over which the Company does not exert significant influence. Tula and PolyCharge are privately-held companies that do not have readily determinable fair values and therefore are measured at cost less impairments, adjusted for observable price changes in orderly transactions for the identical or similar investment of the same issuer. There were no impairments or upward adjustments recorded during the years ended December 31, 2019 or 2018 . These investments are classified within other long-term assets in the consolidated balance sheets. The Company monitors its equity investments, including those measured at fair value and those that do not have readily determinable fair values, for indicators of impairments or upward adjustments, on an ongoing basis. If the Company determines that such an indicator 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 based on discounted cash flows or negotiated transaction values. |
| Use of estimates | Use of estimates —Preparation of consolidated financial statements in conformity with U.S. GAAP requires the use of estimates and assumptions that affect amounts reported therein. Generally, matters subject to estimation and judgment include amounts related to accounts receivable realization, inventory obsolescence, asset impairments, useful lives of intangible and fixed assets, deferred tax asset valuation allowances, income taxes, pension benefit plan assumptions, accruals related to litigation, warranty costs, restructuring, environmental remediation costs, worker’s compensation accruals and healthcare accruals. Due to the inherent uncertainty involved in making estimates, actual results reported in future periods may be based upon amounts that differ from those estimates. |
| Revenue recognition | Revenue recognition —Delphi Technologies recognizes revenue in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 606, Revenue from Contracts with Customers (“ASC 606”). Revenue is recognized when obligations under the terms of a contract with our customer are satisfied; generally this occurs with the transfer of control of our production parts or aftermarket parts. Revenue is measured as the amount of consideration the Company expects to receive in exchange for transferring goods. 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 net sales, while costs of shipping and handling are included in cost of sales. Aftermarket provides certain customers with a right of return. The Company recognizes an estimated return asset (and adjusts for cost of sales) for the right to recover the products returned by the customer. ASC 606 requires that return assets be presented separately from inventory. As of December 31, 2019 , the Company had return assets of $7 million included in other current assets. Refer to Note 15. Revenue and Note 5. Assets for additional information. |
| Net income per share | Net income per share —Basic net income per share is computed by dividing net income attributable to Delphi Technologies by the weighted–average number of ordinary shares outstanding during the period. Diluted net income per share reflects the weighted average dilutive impact of all potentially dilutive securities from the date of issuance and is computed using the treasury stock method by dividing net income attributable to Delphi Technologies by the diluted weighted-average number of ordinary shares outstanding. For periods prior to the Separation, the denominator for basic and diluted net income per share was calculated using the 88.61 million |
| Rebates | Rebates —The Company accrues for rebates pursuant to specific arrangements primarily with certain aftermarket customers. Rebates generally provide for price reductions based upon purchase volumes and are recorded as a reduction of sales as earned by such customers. |
| Research and development | Research and development —Costs are incurred in connection with research and development programs that are expected to contribute to future earnings. Such costs are charged against income as incurred. Total research and development expenses, including engineering, net of third party reimbursements, were $408 million , $448 million and $420 million for the years ended December 31, 2019 , 2018 and 2017 , respectively. |
| Cash and cash equivalents | Cash and cash equivalents —Cash and cash equivalents are defined as short-term, highly liquid investments with original maturities of three months or less. |
| Restricted cash | Restricted cash —Restricted cash includes balances on deposit at financial institutions that have issued letters of credit in favor of Delphi Technologies. |
| Accounts receivable | Accounts receivable —Accounts receivable are recorded at the invoiced amount and do not bear interest. The Company generally does not require collateral for its trade receivables. Sales of receivables are accounted for in accordance with the FASB ASC Topic 860, Transfers and Servicing (“ASC 860”). Agreements which result in true sales of the transferred receivables, as defined in ASC 860, which occur when receivables are transferred to a third party without recourse to the Company, are excluded from amounts reported in the consolidated balance sheets. Cash proceeds received from such sales are included in operating cash flows. Agreements that allow the Company to maintain effective control over the transferred receivables and which do not qualify as a sale, as defined in ASC 860, are accounted for as secured borrowings and recorded in the consolidated balance sheets within accounts receivable, net and short-term debt. The expenses associated with receivables factoring are recorded in the consolidated statements of operations within interest expense. The Company exchanges certain amounts of accounts receivable, primarily in the Asia Pacific region, for bank notes with original maturities greater than three months. The collection of such bank notes are included in operating cash flows based on the substance of the underlying transactions, which are operating in nature. Bank notes held by the Company with original maturities of three months or less are classified as cash and cash equivalents within the consolidated balance sheet, and those with original maturities of greater than three months are classified as notes receivable within other current assets. The Company may hold such bank notes until maturity, exchange them with suppliers to settle liabilities, or sell them to third party financial institutions in exchange for cash. The allowance for doubtful accounts is established based upon analysis of trade receivables for known collectability issues, the aging of the trade receivables at the end of each period and, generally, all accounts receivable balances greater than 90 days past due are fully reserved. The table below summarizes the activity in the allowance for doubtful accounts for the years ended December 31, 2019 , 2018 and 2017 : Year Ended December 31, 2019 2018 2017 (in millions) Balance at beginning of year $ 18 $ 16 $ 9 Provision for doubtful accounts, net of recoveries 11 5 8 Write-offs (5 ) (2 ) (1 ) Foreign currency translation and other — (1 ) — Balance at end of year $ 24 $ 18 $ 16 |
| Inventories | Inventories —Inventories are stated at the lower of cost, determined on a first-in, first-out basis, or net realizable value, including direct material costs and direct and indirect manufacturing costs. Refer to Note 4. Inventories for additional information. Obsolete inventory is identified based on analysis of inventory for known obsolescence issues, and, generally, the market value of inventory on hand in excess of one year’s supply is fully-reserved. From time to time, payments may be received from suppliers. These payments from suppliers are recognized as a reduction of the cost of the material acquired during the period to which the payments relate. In some instances, supplier rebates are received in conjunction with or concurrent with the negotiation of future purchase agreements and these amounts are amortized over the prospective agreement period. |
| Property | Property —Major improvements that materially extend the useful life of property are capitalized. Expenditures for repairs and maintenance are charged to expense as incurred. Depreciation is determined based on a straight-line method over the estimated useful lives of groups of property. Leasehold improvements under capital leases are depreciated over the period of the lease or the life of the property, whichever is shorter. Refer to Note 6. Property, Net for additional information. |
| Pre-production costs related to long-term supply agreements | Pre-production costs related to long-term supply agreements —The Company incurs pre-production engineering, development and tooling costs related to products produced for its customers under long-term supply agreements. Engineering, testing and other costs incurred in the design and development of production parts are expensed as incurred, unless the costs are reimbursable, as specified in a customer contract. As of December 31, 2019 and 2018 , $20 million and $17 million of such contractually reimbursable costs were capitalized, respectively. These amounts are recorded within other current and other long-term assets in the consolidated balance sheets, as further detailed in Note 5. Assets. Special tools represent Delphi Technologies-owned tools, dies, jigs and other items used in the manufacture of customer components that will be sold under long-term supply arrangements, the costs of which are capitalized within property, plant and equipment if the Company has title to the assets. Special tools also include capitalized unreimbursed pre-production tooling costs related to customer-owned tools for which the customer has provided Delphi Technologies a non-cancellable right to use the tool. Delphi Technologies-owned special tools balances are depreciated over the expected life of the special tool or the life of the related vehicle program, whichever is shorter. The unreimbursed costs incurred related to customer-owned special tools that are not subject to reimbursement are capitalized and depreciated over the expected life of the special tool or the life of the related vehicle program, whichever is shorter. At December 31, 2019 and 2018 , the special tools balance, net of accumulated depreciation, was $129 million and $119 million , respectively, included within property, net in the consolidated balance sheets. As of December 31, 2019 and 2018 , the Delphi Technologies-owned special tools balances were $120 million and $109 million , respectively, and the customer-owned special tools balances were $9 million and $10 million , respectively. |
| Valuation of long-lived assets/Goodwill impairment | In the fourth quarter of 2019 and 2018 , the Company completed a qualitative goodwill impairment assessment, and after evaluating the results, events and circumstances of the Company, the Company concluded that sufficient evidence existed to assert qualitatively that it was more likely than not that the estimated fair value of each reporting unit remained in excess of its carrying values. Therefore, a two-step impairment assessment was not necessary. No goodwill impairments were recorded in 2019 , 2018 or 2017 . Refer to Note 8. Intangible Assets and Goodwill for additional information. |
| Fair value measurements | Fair value measurements —The fair values of cash and cash equivalents, accounts and notes receivable, accounts payable, and debt approximates book value. Refer to Note 20. Fair Value of Financial Instruments for the fair values of other financial instruments and obligations. |
| Intangible assets | Intangible assets —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. These indefinite-lived trade name assets are tested for impairment annually, or more frequently when indicators of potential impairment exist. Costs to renew or extend the term of acquired intangible assets are recognized as expense as incurred. Refer to Note 8. Intangible Assets and Goodwill for additional information. |
| Goodwill | Goodwill —Goodwill is the excess of the purchase price over the estimated fair value of identifiable net assets acquired in business combinations. The Company tests goodwill for impairment annually in the fourth quarter, or more frequently when indications of potential impairment exist. The Company monitors the existence of potential impairment indicators throughout the fiscal year. The Company tests for goodwill impairment at the reporting unit level. Our reporting units are operating segments and goodwill relates solely to the Aftermarket operating segment. The impairment test involves first qualitatively assessing goodwill for impairment. If the qualitative assessment is not met the Company then performs a quantitative assessment by first comparing the estimated fair value of each reporting unit to its carrying value, including goodwill. Fair value reflects the price a market participant would be willing to pay in a potential sale of the reporting unit. If the estimated fair value exceeds carrying value, then we conclude that no goodwill impairment has occurred. If the carrying value of the reporting unit exceeds its estimated fair value, a second step is required to measure possible goodwill impairment loss. The second step includes hypothetically valuing the tangible and intangible assets and liabilities of the reporting unit as if the reporting unit had been acquired in a business combination. Then, the implied fair value of the reporting unit’s goodwill is compared to the carrying value of that goodwill. If the carrying value of the reporting unit’s goodwill exceeds the implied fair value of the goodwill, we recognize an impairment loss in an amount equal to the excess, not to exceed the carrying value. Refer to Note 8. Intangible Assets and Goodwill for additional information. |
| Warranty and product recalls | Warranty and product recalls —Expected warranty costs for products sold are recognized at the time of sale of the product based on an estimate of the amount that eventually will be required to settle such obligations. These accruals are based on factors such as past experience, production changes, industry developments and various other considerations. 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 our warranty accrual at the time an obligation becomes probable and can be reasonably estimated. These estimates are adjusted from time to time based on facts and circumstances that impact the status of existing claims. Refer to Note 10. Warranty Obligations for additional information. |
| Income taxes | Income taxes —As described in Note 16. Income Taxes, prior to the Separation the Company’s domestic and foreign operating results were included in the income tax returns of the Former Parent, and the Company accounted for income taxes under the separate return method. Under this approach, the Company determined its deferred tax assets and liabilities and related tax expense as if it were filing separate tax returns. Deferred tax assets and liabilities reflect temporary differences between the amount of assets and liabilities for financial and tax reporting purposes. Such amounts are adjusted, as appropriate, to reflect changes in tax rates expected to be in effect when the temporary differences reverse. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in earnings in the period that includes the enactment date. A valuation allowance is recorded to reduce deferred tax assets to the amount that is more likely than not to be realized. In the event the Company determines it is more likely than not that the deferred tax assets will not be realized in the future, the valuation allowance adjustment to the deferred tax assets will be charged to earnings in the period in which the Company makes such a determination. In determining the provision for income taxes for financial statement purposes, the Company makes certain estimates and judgments which affect its evaluation of the carrying value of its deferred tax assets, as well as its calculation of certain tax liabilities. Refer to Note 16. Income Taxes for additional information. |
| Foreign currency translation | Foreign currency translation —Assets and liabilities of non-U.S. subsidiaries that use a currency other than U.S. dollars as their functional currency are translated to U.S. dollars at end-of-period currency exchange rates. The consolidated statements of operations of non-U.S. subsidiaries are translated to U.S. dollars at average-period currency exchange rates. The effect of translation for non-U.S. subsidiaries is generally reported in other comprehensive income (“OCI”). The effect of remeasurement of assets and liabilities of non-U.S. subsidiaries that use the U.S. dollar as their functional currency is primarily included in cost of sales. Also included in cost of sales are gains and losses arising from transactions denominated in a currency other than the functional currency of a particular entity. Net foreign currency transaction losses and (gains) of $10 million , $(1) million and $(9) million were included as a component of cost of goods sold and other income (expense) in the consolidated statements of operations for the years ended December 31, 2019 , 2018 and 2017 , respectively. |
| Restructuring | Restructuring —Delphi Technologies continually evaluates alternatives to align the business with the changing needs of its customers and to lower operating costs. This includes the realignment of its existing manufacturing capacity, facility closures, or similar actions, either in the normal course of business or pursuant to significant restructuring programs. These actions may result in employees receiving voluntary or involuntary employee termination benefits, which are mainly pursuant to union or other contractual agreements. Voluntary termination benefits are accrued when an employee accepts the related offer. Involuntary termination benefits are accrued upon the commitment to a termination plan and when the benefit arrangement is communicated to affected employees, or when liabilities are determined to be probable and estimable including, at times, consultations with employee works councils or other employee representatives, depending on the existence of a substantive plan for severance or termination. Contract termination costs are recorded when contracts are terminated or when Delphi Technologies no longer derives economic benefit from a contract or ceases to use a leased facility. All other exit costs are expensed as incurred. Refer to Note 11. Restructuring for additional information. |
| Environmental liabilities | Environmental liabilities —Environmental remediation liabilities are recognized when a loss is probable and can be reasonably estimated. Such liabilities generally are not subject to insurance coverage. The cost of each environmental remediation is estimated by engineering, financial, and legal specialists based on current law and considers the estimated cost of investigation and remediation required and the likelihood that, where applicable, other responsible parties will be able to fulfill their commitments. The process of estimating environmental remediation liabilities is complex and dependent primarily on the nature and extent of historical information and physical data relating to a contaminated site, the complexity of the site, the uncertainty as to what remediation and technology will be required, and the outcome of discussions with regulatory agencies and, if applicable, other responsible parties at multi-party sites. In future periods, new laws or regulations, advances in remediation technologies and additional information about the ultimate remediation methodology to be used could significantly change estimates by Delphi Technologies. Refer to Note 14. Commitments and Contingencies for additional information. |
| Derivative financial instruments | Derivative financial instruments —All derivative instruments are required to be reported on the balance sheet at fair value unless the transactions qualify and are designated as normal purchases or sales. Changes in fair value are reported currently through earnings unless they meet hedge accounting criteria. Exposure to fluctuations in currency exchange rates and interest rates are managed by entering into a variety of forward contracts and swaps with various counterparties. Such financial exposures are managed in accordance with the policies and procedures of Delphi Technologies. The Company does not enter into derivative transactions for speculative or trading purposes. As part of the hedging program approval process, the Company identifies the specific financial risk which the derivative transaction will minimize, the appropriate hedging instrument to be used to reduce the risk and the correlation between the financial risk and the hedging instrument. Purchase orders, sales contracts, letters of intent, capital planning forecasts and historical data are used as the basis for determining the anticipated values of the transactions to be hedged. The Company does not enter into derivative transactions that do not have a high correlation with the underlying financial risk. Hedge positions, as well as the correlation between the transaction risks and the hedging instruments, are reviewed on an ongoing basis. Foreign exchange forward contracts are accounted for as hedges of firm or forecasted foreign currency commitments to the extent they are designated and assessed as highly effective. All foreign exchange contracts are marked to market on a current basis. Refer to Note 19. Derivatives and Hedging Activities and Note 20. Fair Value of Financial Instruments for additional information. |
| Asset retirement obligations | Asset retirement obligations —Asset retirement obligations are recognized in accordance with FASB ASC 410, Asset Retirement and Environmental Obligations . Conditional retirement obligations have been identified primarily related to asbestos abatement at certain sites, removal of storage tanks and other disposal costs. Asset retirement obligations were $2 million and $2 million , at December 31, 2019 and 2018 , respectively. |
| Workers Compensation Benefits | Workers’ compensation benefits —Workers’ compensation benefit accruals are actuarially determined and are subject to the existing workers’ compensation laws that vary by location. Accruals for workers’ compensation benefits represent the discounted future cash expenditures expected during the period between the incidents necessitating the employees to be idled and the time when such employees return to work, are eligible for retirement or otherwise terminate their employment. |
| Share-based compensation | Share-based compensation —The Delphi Technologies PLC Long-Term Incentive Plan (the “PLC LTIP”) allows for the grant of share-based awards for long-term compensation to the employees, directors, consultants and advisors of the Company. The Company had no share-based compensation plans prior to the Separation; however certain of our employees and non-employee directors participated in the Former Parent’s share-based compensation arrangement, the Delphi Automotive PLC Long-Term Incentive Plan, as amended and restated effective April 23, 2015 (the “Former Parent Plan”). Grants of restricted stock units (“RSUs”) to executives and non-employee directors were made subsequent to the Separation under the PLC LTIP in 2017 , 2018 and 2019 . Grants of RSUs were made under the Former Parent Plan in each year from 2012 to 2017. Outstanding awards at the time of the Separation were converted to awards under the PLC LTIP. Share-based compensation expense within the consolidated financial statements for periods prior to the Separation was allocated to Delphi Technologies based on the awards and terms previously granted to Delphi Technologies employees while part of the Former Parent, and includes the cost of Delphi Technologies employees who participated in the Former Parent’s Plan, as well as an allocated portion of the cost of the Former Parent’s senior management awards. The RSU awards to executives include a time-based vesting portion and a performance-based vesting portion. The performance-based vesting portion includes performance and market conditions in addition to service conditions. The grant date fair value of the RSUs is determined based on the closing price of the underlying ordinary shares on the date of the grant of the award, including an estimate for forfeitures, and a contemporaneous valuation performed by an independent valuation specialist with respect to awards with market conditions. The Company accounts for compensation expense based upon the grant date fair value of the awards applied to the best estimate of ultimate performance against the respective targets on a straight-line basis over the requisite vesting period of the awards. The performance conditions require management to make assumptions regarding the likelihood of achieving certain performance goals. Changes in these performance assumptions, as well as differences in actual results from management’s estimates, could result in estimated or actual values different from previously estimated fair values. Modifications to the terms of share-based awards are treated as an exchange of the original award for a new award resulting in total compensation cost equal to the grant-date fair value of the original award plus any incremental value of the modification to the award. The calculation of the incremental value is based on the excess of the fair value of the new (modified) award based on current circumstances over the fair value of the original award measured immediately before its terms are modified. To the extent there is incremental compensation cost relating to the newly modified award, it is recognized ratably over the requisite service period. Refer to Note 22. Share-Based Compensation for additional information. |
| Pension and Other Post-Retirement Benefits (OPEB) | Pension and Other Post-Retirement Benefits (OPEB) —Certain of the Company’s non-U.S. subsidiaries sponsor defined-benefit plans, which generally provide benefits based on negotiated amounts for each year of service. Certain Delphi Technologies employees, primarily in the United Kingdom (“U.K.”), France, Mexico and Turkey, participate in these plans (collectively, the “Direct Plans”). The Direct Plans, which relate solely to the Company, are included within the consolidated financial statements. In addition to the Direct Plans, prior to the Separation certain of the Company’s employees in Germany and the U.S. participated in defined benefit pension plans (collectively, the “Shared Plans”) sponsored by the Former Parent that included Delphi Technologies employees as well as employees of other subsidiaries of the Former Parent. The related pension and other postemployment expenses of the Shared Plans were charged to Delphi Technologies based primarily on the service cost of active participants. Following the Separation, Delphi Technologies’ portion of the defined-benefit pension plans were separated from the Former Parent’s defined benefit pension plans. As a result, the funded status for each plan is reflected in the Company’s consolidated balance sheet as of December 31, 2019 and 2018 . Refer to Note 13. Pension Benefits for additional information. |
| Recently adopted accounting pronouncements and not yet adopted | Recently adopted accounting pronouncements —Delphi Technologies adopted Accounting Standards Update (“ASU”) 2016-02, Leases (Topic 842), in the first quarter of 2019 using the optional modified retrospective transition method and did not recast the comparative periods. This ASU requires lessees to recognize a lease liability and a right-of-use asset on the balance sheet for all leases, with the exception of short-term leases. Delphi Technologies elected the package of practical expedients, related to existing leases at the time of adoption, that allowed the Company to carry forward the accounting assessments for: i) whether contracts are or contain leases, ii) the lease classification and iii) the initial direct costs. Delphi Technologies also elected the practical expedient related to existing land easements, that allowed the Company to carry forward the accounting treatment for land easements in existing agreements. The adoption of this guidance resulted in the recognition of operating lease right-of-use assets and operating lease liabilities of approximately $107 million and $115 million , respectively, on the Company’s consolidated balance sheet as of December 31, 2019 . The adoption did not have a material impact on its consolidated statements of operations or cash flows. Refer to Note 7. Leases for additional information. Delphi Technologies adopted ASU 2018-07, Compensation-Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting in the first quarter of 2019 . This guidance expands the scope of ASC Topic 718, which currently only includes share-based payments to employees, to include share-based payments issued to nonemployees for goods or services. Consequently, the accounting for share-based payments to nonemployees and employees will be substantially aligned. The adoption of this guidance did not have a material impact on the Company’s consolidated financial statements. Recently issued accounting pronouncements not yet adopted —In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments . This guidance requires the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions and reasonable and supportable forecasts. This guidance also requires enhanced disclosures regarding significant estimates and judgments used in estimating credit losses. The new guidance is effective for fiscal years beginning after December 15, 2019. Early adoption is permitted for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The adoption of this guidance will not have a material impact on the Company’s consolidated financial statements. In January 2017, the FASB issued ASU 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment . This guidance simplifies how an entity is required to test goodwill for impairment by eliminating step two from the goodwill impairment test, which measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount. Under the new guidance, if a reporting unit’s carrying amount exceeds its fair value, an entity will record an impairment charge based on that difference. The impairment charge will be limited to the amount of goodwill allocated to that reporting unit. The standard will be applied prospectively and is effective for annual and interim impairment tests performed in periods beginning after December 15, 2019. Early adoption is permitted. The adoption of this guidance will not have a material impact on the Company’s consolidated financial statements. In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement. This guidance amends ASC 820 to add, remove and clarify certain disclosure requirements related to fair value measures. The new guidance is effective for fiscal years beginning after December 15, 2019, including interim periods within that fiscal year. Early adoption is permitted. The adoption of this guidance will not have a material impact on the Company’s financial statements. In August 2018, the FASB issued ASU 2018-14, Compensation-Retirement Benefits-Defined Benefit Plans-General (Subtopic 715-20): Disclosure Framework-Changes to the Disclosure Requirements for Defined Benefit Plans. This guidance amends ASC 715 to add, remove and clarify certain disclosure requirements related to defined benefit pension and other postretirement plans. The new guidance is effective for fiscal years ending after December 31, 2020. Early adoption is permitted. The adoption of this guidance is not expected to have a material impact on the Company’s financial statements. |
