CAUTIONARY STATEMENTS FOR FORWARD-LOOKING STATEMENTS

Statements in this Quarterly Report on Form 10-Q (“Form 10-Q”) (including Management's Discussion and Analysis of Financial Condition and Results of Operations) may constitute forward-looking statements as contemplated by the 1995 Private Securities Litigation Reform Act (the “Act”) that are based on management's current outlook, expectations, estimates and projections. Words such as "anticipates," "believes," "continues," "could," "designed," "effect," "estimates," "evaluates," "expects," "forecasts," "goal," "initiative," "intends," "outlook," "plans," "potential," "project," "pursue," "seek," "should," "target," "when," "would," and variations of such words and similar expressions are intended to identify such forward-looking statements. Further, all statements, other than statements of historical fact contained or incorporated by reference in this Form 10-Q, that we expect or anticipate will or may occur in the future regarding our financial position, business strategy and measures to implement that strategy, including changes to operations, competitive strengths, goals, expansion and growth of our business and operations, plans, references to future success and other such matters, are forward-looking statements. Accounting estimates, such as those described under the heading "Critical Accounting Policies" in Item 7 of our Annual Report on Form 10-K for the year ended December 31, 2018 (“Form 10-K”), are inherently forward-looking. All forward-looking statements are based on assumptions and analyses made by us in light of our experience and our perception of historical trends, current conditions and expected future developments, as well as other factors we believe are appropriate in the circumstances. Forward-looking statements are not guarantees of performance and the Company's actual results may differ materially from those expressed, projected, or implied in or by the forward-looking statements.

You should not place undue reliance on these forward-looking statements, which speak only as of the date of this Form 10-Q. Forward-looking statements are subject to risks and uncertainties, many of which are difficult to predict and generally beyond our control, that could cause actual results to differ materially from those expressed, projected or implied in or by the forward-looking statements. These risks and uncertainties, among others, include: our dependence on automotive and truck production, both of which are highly cyclical; our reliance on major OEM customers; commodities availability and pricing; supply disruptions; fluctuations in interest rates and foreign currency exchange rates; availability of credit; our dependence on key management; our dependence on information systems; the uncertainty of the global economic environment; the outcome of existing or any future legal proceedings, including litigation with respect to various claims; future changes in laws and regulations in the countries in which we operate; and the other risks noted in reports that we file with the Securities and Exchange Commission, including Item 1A, "Risk Factors" in our most recently-filed Form 10-K. We do not undertake any obligation to update or announce publicly any updates to or revisions to any of the forward-looking statements in this Form 10-Q to reflect any change in our expectations or any change in events, conditions, circumstances, or assumptions underlying the statements.

This section and the discussions contained in Item 1A, "Risk Factors," and in Item 7, subheading "Critical Accounting Policies" in our most recently-filed Form 10-K are intended to provide meaningful cautionary statements for purposes of the safe harbor provisions of the Act. This should not be construed as a complete list of all of the economic, competitive, governmental, technological and other factors that could adversely affect our expected consolidated financial position, results of operations or liquidity. Additional risks and uncertainties, including without limitation those not currently known to us or that we currently believe are immaterial, also may impair our business, operations, liquidity, financial condition and prospects.

Use of Non-GAAP Financial Measures

In addition to results presented in accordance with accounting principles generally accepted in the United States of America (“GAAP”), this report includes non-GAAP financial measures. The Company believes these non-GAAP financial measures provide additional information that is useful to investors in understanding the underlying performance and trends of the Company. Readers should be aware that non-GAAP financial measures have inherent limitations and should be cautious with respect to the use of such measures. To compensate for these limitations, we use non-GAAP measures as comparative tools, together with GAAP measures, to assist in the evaluation of our operating performance or financial condition. We ensure that these measures are calculated using the appropriate GAAP components in their entirety and that they are computed in a manner intended to facilitate consistent period-to-period comparisons. The Company's method of calculating these non-GAAP measures may differ from methods used by other companies. These non-GAAP measures should not be considered in isolation or as a substitute for those financial measures prepared in accordance with GAAP. Where non-GAAP financial measures are used, the most directly comparable GAAP or regulatory financial measure, as well as the reconciliation to the most directly comparable GAAP financial measure, can be found in this report.

BORGWARNER INC. AND CONSOLIDATED SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

(1)      Basis of Presentation

The accompanying unaudited Condensed Consolidated Financial Statements of BorgWarner Inc. and Consolidated Subsidiaries (the “Company”) have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes necessary for a comprehensive presentation of financial position, results of operations and cash flow activity required by GAAP for complete financial statements. In the opinion of management, all normal recurring adjustments necessary for a fair statement of results have been included. Operating results for the three and six months ended June 30, 2019 are not necessarily indicative of the results that may be expected for the year ending December 31, 2019. The balance sheet as of December 31, 2018 was derived from the audited financial statements as of that date. For further information, refer to the Consolidated Financial Statements and Footnotes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2018.

Certain prior period amounts have been reclassified to conform to current period presentation. Management makes estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and accompanying notes, as well as the amounts of revenues and expenses reported during the periods covered by those financial statements and accompanying notes. Actual results could differ from these estimates.

(2) New Accounting Pronouncements

Recently Adopted Accounting Standards

In February 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2016-02, "Leases (Topic 842)." Under this guidance, a lease is a contract, or part of a contract, that conveys the right to control the use of an identified asset for a period of time in exchange for consideration. Lessees are required to recognize a right-of-use asset and a lease liability for leases with a term more than 12 months, including operating leases defined under previous GAAP. This guidance was effective for interim and annual reporting periods beginning after December 15, 2018.

The Company adopted Accounting Standards Codification ("ASC") 842 as of January 1, 2019, using the optional transition method provided in ASU No. 2018-11, "Leases (Topic 842): Targeted Improvements." Under this method, the Company recorded an adjustment as of the effective date and did not include any retrospective adjustments to comparative periods to reflect the adoption of ASC 842. In addition, the Company elected the package of practical expedients permitted under the transition guidance within ASC 842, which among other things, does not require the Company to reassess whether existing contracts contain leases, classification of leases identified, nor classification and treatment of initial direct costs capitalized under ASC 840. The Company also elected the practical expedients to combine the lease and non-lease components. The Company did not elect the practical expedient to apply hindsight as part of the leases evaluation. Additionally, the Company elected the practical expedient under ASU No. 2018-01, "Leases (Topic 842): Land Easement Practical Expedient for Transition to Topic 842", which allows an entity to not reassess whether any existing land easements are or contain leases.

The majority of the Company’s global lease portfolio represents leases of real estate, such as manufacturing facilities, warehouses, and office buildings, while the remainder represents leases of

5

personal property, such as vehicle leases, manufacturing and IT equipment. The Company determines whether a contract is or contains a lease at contract inception. The majority of the Company's lease arrangements are comprised of fixed payments and a limited number of these arrangements include a variable payment component based on certain index fluctuations.

Adoption of ASC 842 resulted in the recording of lease right-of-use assets ("lease assets") and lease liabilities of approximately $104 million and $103 million, respectively, as of January 1, 2019. The adoption did not impact consolidated net earnings and had no impact on cash flows.

The changes made to our Consolidated Balance Sheet as of January 1, 2019 for the adoption of ASC 842 were as follows:

(in millions)	Balance at December 31, 2018		Adjustments due to ASC 842		Balance at January 1, 2019
Other non-current assets	$	502	$	104	$	606
Accounts payable and accrued expenses	$	2,144	$	23	$	2,167
Other non-current liabilities	$	357	$	80	$	437

In February 2018, the FASB issued ASU No. 2018-07, "Compensation - Stock Compensation (Topic 718)." It expands the scope of the employee share-based payments guidance, which currently only includes share-based payments issued to employees, to also include share-based payments issued to nonemployees for goods and services. This guidance is effective for interim and annual periods beginning after December 15, 2018. The Company adopted this guidance as of January 1, 2019 and there was no impact to the consolidated financial statements.

Accounting Standards Not Yet Adopted

In August 2018, the FASB issued ASU No. 2018-15, "Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40)." It requires implementation costs incurred by customers in cloud computing arrangements to be deferred and recognized over the term of the arrangement, if those costs would be capitalized by the customer in a software licensing arrangement under the internal-use software guidance (Subtopic 350-40). This guidance is effective for interim and annual periods beginning after December 15, 2019. Early adoption is permitted. The Company is currently assessing the impact of this guidance on its consolidated financial statements.

In August 2018, the FASB issued Accounting Standards Update ("ASU") No. 2018-14, "Compensation - Retirement Benefits - Defined Benefit Plans - General (Subtopic 715-20)." The new standard (i) requires the removal of disclosures that are no longer considered cost beneficial; (ii) clarifies specific requirements of certain disclosures; and (iii) adds new disclosure requirements, including the weighted average interest crediting rates for cash balance plans and other plans with promised interest crediting rates, and reasons for significant gains and losses related to changes in the benefit obligation. This guidance is effective for annual periods beginning after December 15, 2020 and early adoption is permitted. The Company is currently assessing the guidance and will include enhanced disclosures in the consolidated financial statements upon adoption.

In August 2018, the FASB issued ASU No. 2018-13, "Fair Value Measurement (Topic 820)." It removes disclosure requirements on fair value measurements including the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, the policy for timing of transfers between levels, and the valuation processes for Level 3 fair value measurements. It also amends and clarifies certain disclosures and adds new disclosure requirements including the changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements, and the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. This guidance is effective for interim and annual periods beginning

6

after December 15, 2019. An entity is permitted to early adopt any removed or modified disclosures and delay adoption of the additional disclosures until the effective date. The Company is currently assessing the guidance and does not expect this guidance to have a material impact on its consolidated financial statements.

In June 2016, the FASB issued ASU No. 2016-13, "Financial Instruments - Credit Losses (Topic 326)." It replaces the current incurred loss impairment method with a new method that reflects expected credit losses. Under this new model an entity would recognize an impairment allowance equal to its current estimate of credit losses on financial assets measured at amortized cost. This guidance is effective for fiscal years beginning after December 15, 2019, with early adoption permitted. The Company is currently evaluating the impact this guidance will have on its consolidated financial statements.

(3) Revenue from Contracts with Customers

The Company manufactures and sells products, primarily to OEMs of light vehicles and, to a lesser extent, to other OEMs of commercial vehicles, off-highway vehicles, certain tier one vehicle systems suppliers and into the aftermarket. 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 606, "Revenue from Contracts with Customers", until volumes are contractually known. Revenue is recognized when performance obligations under the terms of a contract are satisfied, which generally occurs with the transfer of control of the Company's products. For most of the Company's products, transfer of control occurs upon shipment or delivery; however, a limited number of the Company's 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. The Company recorded a contract asset of $10 million and $11 million at June 30, 2019 and December 31, 2018, respectively, for these arrangements. These amounts are reflected in Prepayments and other current assets in the Condensed Consolidated Balance Sheet.

Revenue is measured at the amount of consideration the Company expects to receive in exchange for transferring the goods. 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 limited 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. As a result of these arrangements, the Company recognized a liability of $3 million and $6 million at June 30, 2019 and December 31, 2018. These amounts are reflected in Accounts payable and accrued expenses in the Condensed Consolidated Balance Sheet.

The Company’s payment terms with customers are customary and vary by customer and geography but typically range from 30 to 90 days. The Company has evaluated the terms of its arrangements and determined that they do not contain significant financing components. The Company provides warranties on some of its products. Provisions for estimated expenses related to product warranty are made at the time products are sold. Refer to Note 9, "Product Warranty," to the Condensed Consolidated Financial Statements for more information. 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 606 and accounts for shipping and handling activities as a fulfillment cost.

In limited instances, certain customers have provided payments in advance of receiving related products, typically at the onset of an arrangement prior to the beginning of production. These contract liabilities are reflected as Accounts payable and accrued expenses and Other non-current liabilities in the

7

Condensed Consolidated Balance Sheet and were $11 million and $16 million at June 30, 2019 and $13 million and $17 million at December 31, 2018, respectively. These amounts are reflected as revenue over the term of the arrangement (typically 3 to 7 years) as the underlying products are shipped.

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, when the 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 3 to 7 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. The Company had $28 million and $29 million recorded in Prepayments and other current assets in the Condensed Consolidated Balance Sheet at June 30, 2019 and December 31, 2018, respectively. The Company had $187 million recorded in Other non-current assets in the Condensed Consolidated Balance Sheet at June 30, 2019 and December 31, 2018.

The Company's business is comprised of two reporting segments: Engine and Drivetrain. Refer to Note 21, "Reporting Segments," to the Condensed Consolidated Financial Statements for more information. The following table represents a disaggregation of revenue from contracts with customers by segment and region:

(4) Research and Development Expenditures

The Company's net Research & Development ("R&D") expenditures are included in selling, general and administrative expenses of the Condensed Consolidated Statements of Operations. Customer reimbursements are netted against gross R&D expenditures as they are considered a recovery of cost. Customer reimbursements for prototypes are recorded net of prototype costs based on customer contracts, typically either when the prototype is shipped or when it is accepted by the customer. Customer reimbursements for engineering services are recorded when performance obligations are

8

satisfied in accordance with the contract. Financial risks and rewards transfer upon shipment, acceptance of a prototype component by the customer or upon completion of the performance obligation, as stated in the respective customer agreement.

The following table presents the Company’s gross and net expenditures on R&D activities:

	Three Months Ended June 30,						Six Months Ended June 30,
(in millions)	2019			2018			2019			2018
Gross R&D expenditures	$	128		$	134		$	249		$	264
Customer reimbursements	(15		)	(22		)	(32		)	(35		)
Net R&D expenditures	$	113		$	112		$	217		$	229

The Company has contracts with several customers at the Company's various R&D locations. None of the Company's R&D-related customer reimbursement contracts exceeded 5% of net R&D expenditures in any of the periods presented.

(5) Other Expense, net

Items included in other expense, net consist of:

	Three Months Ended June 30,						Six Months Ended June 30,
(in millions)	2019			2018			2019		2018
Restructuring expense	$	13		$	31		$	27	$	39

Other expense (income)	(2		)	(2		)	12		(7		)
Other expense, net	$	16		$	30		$	45	$	35

During the three and six months ended June 30, 2019, the Company recorded restructuring expense of $13 million and $27 million, respectively. During the three and six months ended June 30, 2018, the Company recorded restructuring expense of $31 million and $39 million, respectively. This restructuring expense primarily relates to Drivetrain and Engine segment actions designed to improve future profitability and competitiveness. Refer to Note 19, "Restructuring," to the Condensed Consolidated Financial Statements for more information.

During the three and six months ended June 30, 2019, the Company recorded expenses related to the Company's review of strategic acquisition targets, including the 20% equity interest in Romeo Power Technology, of $5 million and $6 million, respectively. During the three and six months ended June 30, 2018, the Company recorded expenses of $1 million and $3 million, respectively, primarily related to professional fees associated with divestiture activities for the non-core pipe and thermostat product lines. Refer to Note 23, "Assets and Liabilities Held For Sale," to the Condensed Consolidated Financial Statements for more information.

During the first six months of 2019, the Company recorded $14 million of expense related to the receipt of a final unfavorable arbitration decision associated with the resolution of a matter related to a previous acquisition.

During the first six months of 2018, the Company recorded a gain of approximately $4 million related to the settlement of a commercial contract for an entity acquired in the 2015 Remy acquisition.

(6) Income Taxes

The Company's provision for income taxes is based upon an estimated annual tax rate for the year applied to federal, state and foreign income. On a quarterly basis, the annual effective tax rate is adjusted, as appropriate, based upon changed facts and circumstances, if any, as compared to those forecasted at the beginning of the fiscal year and each interim period thereafter.

The Company's effective tax rate for the six months ended June 30, 2019 was 31.7%. This rate includes reductions of income tax expense of $7 million related to restructuring expense, $6 million related to other postretirement expense, and $5 million related to other one-time adjustments. This rate also includes an increase in income tax expense of $22 million due to the U.S. Department of the Treasury's issuance of the final regulations in the first quarter of 2019 related to the calculation of the one-time transition tax.

The Company's effective tax rate for the six months ended June 30, 2018 was 19.4%. This rate includes income tax expense of $1 million related to a commercial settlement gain, and reductions of income tax expense of $8 million related to restructuring expense, $13 million related to adjustments to measurement period provisional estimates associated with the Tax Cuts and Jobs Act of 2017, $21 million related to an increase to our deferred tax asset due to the Company's ability to record a tax benefit for certain foreign tax credits now available due to actions the Company took in the second quarter, and $10 million for other one-time tax adjustments.

The annual effective tax rates differ from the U.S. statutory rate primarily due to foreign rates which differ from those in the U.S., U.S. taxes on foreign earnings, the realization of certain business tax credits, including foreign tax credits, and favorable permanent differences between book and tax treatment for certain items, including equity in affiliates' earnings.

(7) Inventories, net

Certain U.S. inventories are measured by the last-in, first-out (“LIFO”) method at the lower of cost or market, while other U.S. and foreign operations use the first-in, first-out (“FIFO”) or average-cost methods at the lower of cost and net realizable value. Inventories consisted of the following:

	June 30,			December 31,
(in millions)	2019			2018
Raw material and supplies	$	520		$	485
Work in progress	117			114

As of June 30, 2019 and December 31, 2018, accounts payable of $61 million and $104 million, respectively, were related to property, plant and equipment purchases.

Interest costs capitalized for the six months ended June 30, 2019 and 2018 were $9 million and $11 million, respectively.

(9) Product Warranty

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. Management believes that the warranty accrual is appropriate; however, actual claims incurred could differ from the original estimates, requiring adjustments to the accrual.

The following table summarizes the activity in the product warranty accrual accounts:

(in millions)	2019			2018
Beginning balance, January 1	$	103		$	112
Provisions for current period sales	27			26

Long-term debt, net of current portion	$	1,929	$	1,941

In July 2016, the Company terminated interest rate swaps which had the effect of converting $384 million of fixed rate notes to variable rates. The gain on the termination was recorded as an increase to the notes and is being amortized as a reduction to interest expense over the remaining terms of the notes. The unamortized gain related to these swap terminations was $1 million and $2 million as of June 30, 2019 and December 31, 2018, respectively, on the 4.625% notes.

The weighted average interest rate on short-term borrowings outstanding as of June 30, 2019 and December 31, 2018 was 3.4% and 4.3%, respectively. The weighted average interest rate on all borrowings outstanding, including the effects of outstanding swaps, as of June 30, 2019 and December 31, 2018 was 3.4%.

The Company has a $1.2 billion multi-currency revolving credit facility, which includes a feature that allows the Company's facility to be increased to $1.5 billion with approval of the bank group. The facility provides for borrowings through June 29, 2022. The Company has one key financial covenant as part of the credit agreement which is a debt to Earnings Before Interest, Taxes, Depreciation and Amortization ("EBITDA ") ratio. The Company was in compliance with the financial covenant at June 30, 2019. At June 30, 2019 and December 31, 2018, the Company had no outstanding borrowings under this facility.

The Company's commercial paper program allows the Company to issue short-term, unsecured commercial paper notes up to a maximum aggregate principal amount outstanding of $1.2 billion. Under this program, the Company may issue notes from time to time and use the proceeds for general corporate purposes. The Company had no outstanding borrowings under this program as of June 30, 2019 and December 31, 2018.

The total current combined borrowing capacity under the multi-currency revolving credit facility and commercial paper program cannot exceed $1.2 billion.

As of June 30, 2019 and December 31, 2018, the estimated fair values of the Company’s senior unsecured notes totaled $2,142 million and $2,058 million, respectively. The estimated fair values were $82 million more than their carrying value at June 30, 2019 and $8 million less than their carrying value

12

at December 31, 2018. Fair market values of the senior unsecured notes are developed using observable values for similar debt instruments, which are considered Level 2 inputs as defined by ASC 820. The carrying values of the Company's multi-currency revolving credit facility and commercial paper program approximates fair value. The fair value estimates do not necessarily reflect the values the Company could realize in the current markets.

The Company had outstanding letters of credit of $38 million and $43 million at June 30, 2019 and December 31, 2018, respectively. The letters of credit typically act as guarantees of payment to certain third parties in accordance with specified terms and conditions.

(11) Fair Value Measurements

ASC 820 emphasizes that fair value is a market-based measurement, not an entity specific measurement. Therefore, a fair value measurement should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering market participant assumptions in fair value measurements, ASC 820 establishes a fair value hierarchy, which prioritizes the inputs used in measuring fair values as follows:

Level 1: Observable inputs such as quoted prices for identical assets or liabilities in active markets;

Level 2: Inputs, other than quoted prices in active markets, that are observable either directly or indirectly; and

Level 3: Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions.

Assets and liabilities measured at fair value are based on one or more of the following three valuation techniques noted in ASC 820:

A. Market approach: Prices and other relevant information generated by market transactions involving identical or comparable assets, liabilities or a group of assets or liabilities, such as a business.

B. Cost approach: Amount that would be required to replace the service capacity of an asset (replacement cost).

C. Income approach: Techniques to convert future amounts to a single present amount based upon market expectations (including present value techniques, option-pricing and excess earnings models).

The following tables classify assets and liabilities measured at fair value on a recurring basis as of June 30, 2019 and December 31, 2018:

			Basis of fair value measurements
(in millions)	Balance at June 30, 2019		Quoted prices in active markets for identical items (Level 1)		Significant other observable inputs (Level 2)		Significant unobservable inputs (Level 3)		Valuation technique

(12) Financial Instruments

The Company’s financial instruments include cash and marketable securities. Due to the short-term nature of these instruments, their book value approximates their fair value. The Company’s financial instruments may include long-term debt, interest rate and cross-currency swaps, commodity derivative contracts and foreign currency derivative contracts. All derivative contracts are placed with counterparties that have an S&P, or equivalent, investment grade credit rating at the time of the contracts’ placement. At June 30, 2019 and December 31, 2018, the Company had no derivative contracts that contained credit risk related contingent features.

The Company uses certain commodity derivative contracts to protect against commodity price changes related to forecasted raw material and component purchases. The Company primarily utilizes forward and option contracts, which are designated as cash flow hedges. At June 30, 2019 and December 31, 2018, the following commodity derivative contracts were outstanding:

	Commodity derivative contracts
Commodity	Volume hedged June 30, 2019	Volume hedged December 31, 2018	Units of measure	Duration
Copper	120	257	Metric Tons	Dec - 19

The Company manages its interest rate risk by balancing its exposure to fixed and variable rates while attempting to optimize its interest costs. The Company selectively uses interest rate swaps to reduce market value risk associated with changes in interest rates (fair value hedges). At June 30, 2019 and December 31, 2018, the Company had no outstanding interest rate swaps.

14

The Company uses foreign currency forward and option contracts to protect against exchange rate movements for forecasted cash flows, including capital expenditures, purchases, operating expenses or sales transactions designated in currencies other than the functional currency of the operating unit. In addition, the Company uses foreign currency forward contracts to hedge exposure associated with our net investment in certain foreign operations (net investment hedges). The Company has also designated its Euro denominated debt as a net investment hedge of the Company's investment in a European subsidiary. Foreign currency derivative contracts require the Company, at a future date, to either buy or sell foreign currency in exchange for the operating units’ local currency. At June 30, 2019 and December 31, 2018, the following foreign currency derivative contracts were outstanding:

Foreign currency derivatives (in millions)

The Company selectively uses cross-currency swaps to hedge the foreign currency exposure associated with our net investment in certain foreign operations (net investment hedges). At June 30, 2019 and December 31, 2018, the following cross-currency swap contracts were outstanding:

	Cross-Currency Swaps

At June 30, 2019 and December 31, 2018, the following amounts were recorded in the Condensed Consolidated Balance Sheets as being payable to or receivable from counterparties under ASC 815:

(in millions)	Assets					Liabilities
Derivatives designated as hedging instruments Under 815:	Location	June 30, 2019		December 31, 2018		Location	June 30, 2019		December 31, 2018

Derivatives not designated as hedging instruments
Foreign currency	Prepayments and other current assets	$	1	$	1	Accounts payable and accrued expenses	$	—	$	—

Effectiveness for cash flow hedges is assessed at the inception of the hedging relationship and quarterly, thereafter. Gains and losses arising from these contracts that are included in the assessment of effectiveness are deferred into accumulated other comprehensive income (loss) ("AOCI") and reclassified into income as the underlying operating transactions are recognized. These realized gains or losses offset the hedged transaction and are recorded on the same line in the statement of operations. The initial value of any component excluded from the assessment of effectiveness will be recognized in income using a systematic and rational method over the life of the hedging instrument. Any difference between the change in fair value of the excluded component and amounts recognized in income under that systematic and rational method will be recognized in AOCI.

Effectiveness for net investment hedges is assessed at the inception of the hedging relationship and quarterly, thereafter. Gains and losses arising from these contracts that are included in the assessment of effectiveness are deferred into foreign currency translation adjustments and only released when the subsidiary being hedged is sold or substantially liquidated. The initial value of any component excluded from the assessment of effectiveness will be recognized in income using a systematic and rational method over the life of the hedging instrument. Any difference between the change in fair value of the excluded component and amounts recognized in income under that systematic and rational method will be recognized in AOCI.

The table below shows deferred gains (losses) reported in AOCI as well as the amount expected to be reclassified to income in one year or less. The amount expected to be reclassified to income in one year or less assumes no change in the current relationship of the hedged item at June 30, 2019 market rates.

(13) Retirement Benefit Plans

The Company has a number of defined benefit pension plans and other postretirement benefit plans covering eligible salaried and hourly employees and their dependents. The estimated contributions to the Company's defined benefit pension plans for 2019 range from $15 million to $25 million, of which $8 million has been contributed through the first six months of the year. The other postretirement benefit plans, which provide medical and life insurance benefits, are unfunded plans.

During the three months ended June 30, 2019, the Company settled approximately $50 million of its pension projected benefit obligation by liquidating approximately $50 million in plan assets through a lump-sum disbursement made to an insurance company. Pursuant to this agreement, the insurance company unconditionally and irrevocably guarantees all future payments to certain participants that were receiving payments from the U.S. pension plan. The insurance company assumes all investment risk associated with the assets that were delivered as part of this transaction. Additionally, during the three months ended June 30, 2019, the Company discharged certain U.S. pension plan obligations by making lump-sum payments of $13 million to former employees of the Company. As a result, the Company settled $63 million of projected benefit obligation by liquidating pension plan assets and recorded a non-cash settlement loss of $26 million related to the accelerated recognition of unamortized losses.

(14) Stock-Based Compensation

The Company has granted restricted common stock and restricted stock units (collectively, "restricted stock") and performance share units as long-term incentive awards to employees and non-employee directors under the BorgWarner Inc. 2014 Stock Incentive Plan, as amended ("2014 Plan") and the BorgWarner Inc. 2018 Stock Incentive Plan ("2018 Plan"). The Company's Board of Directors adopted the 2018 Plan as a replacement to the 2014 Plan in February 2018, and the Company's stockholders approved the 2018 Plan at the annual meeting of stockholders on April 25, 2018. After stockholders approved the 2018 Plan, the Company could no longer make grants under the 2014 Plan. The shares that were available for issuance under the 2014 Plan were cancelled upon approval of the 2018 Plan. The 2018 Plan authorizes the issuance of a total of 7 million shares, of which approximately 6 million shares were available for future issuance as of June 30, 2019.

Restricted stock In the first six months of 2019, the Company granted restricted stock in the amounts of 1,031,513 shares and 23,880 shares to employees and non-employee directors, respectively. Restricted stock granted to employees generally vests 50% after two years and the remainder after three years. Restricted stock granted to non-employee directors generally vests on the first anniversary of the date of grant. The Company recognizes the value of the restricted stock, which is equal to the market value of the Company’s common stock on the date of grant, as compensation expense ratably over the restricted stock's vesting period. As of June 30, 2019, the Company had $53 million of unrecognized compensation expense that will be recognized over a weighted average period of 2.1 years. The

19

Company recorded restricted stock compensation expense of $7 million and $5 million for the three months ended June 30, 2019 and 2018, respectively, and $14 million and $12 million for the six months ended June 30, 2019 and 2018, respectively.

A summary of the Company’s nonvested restricted stock for the six months ended June 30, 2019 is as follows:

	Shares subject to restriction (thousands)		Weighted average grant date fair value
Nonvested at December 31, 2018	1,516		$	42.97
Granted	930		$	41.92

Forfeited	(37	)	$	45.13
Nonvested at June 30, 2019	1,835		$	44.40

Total Stockholder Return Performance Share Units The Company grants performance share units to members of senior management that vest at the end of three-year periods based on the Company's total stockholder return relative to a peer group of companies. The Company recorded compensation expense of $3 million and $2 million for the six months ended June 30, 2019 and 2018, respectively.

A summary of the status of the Company’s nonvested total stockholder return performance share units for the six months ended June 30, 2019 is as follows:

	Number of shares (thousands)		Weighted average grant date fair value
Nonvested at December 31, 2018	297		$	60.35
Granted	190		$	51.52
Forfeited	(9	)	$	55.30
Nonvested at March 31, 2019	478		$	56.93
Granted	5		$	51.59
Forfeited	(56	)	$	55.67
Nonvested at June 30, 2019	427		$	57.03

Relative Revenue Growth Performance Share Units The Company also grants performance share units to members of senior management that vest based on the Company's revenue growth relative to the vehicle market over three-year performance periods. The Company recorded compensation expense of $1 million for both of the three months ended June 30, 2019 and 2018 and $8 million for the six months ended June 30, 2018.

20

A summary of the status of the Company’s nonvested relative revenue growth performance share units for the six months ended June 30, 2019 is as follows:

	Number of shares (thousands)		Weighted average grant date fair value
Nonvested at December 31, 2018	297		$	47.03
Granted	190		$	41.90
Forfeited	(9	)	$	44.12
Nonvested at March 31, 2019	478		$	45.04
Granted	5		$	41.92
Forfeited	(56	)	$	44.24
Nonvested at June 30, 2019	427		$	45.11

In 2018, the Company modified the vesting provisions of restricted stock and performance share unit grants made to certain retiring executive officers to allow certain of the outstanding awards, that otherwise would have been forfeited, to vest upon retirement. This resulted in net restricted stock and performance share unit compensation expense of $2 million in the six months ended June 30, 2019 and a net reduction to expense of $4 million in the six months ended June 30, 2018, respectively.

(17) Leases

The majority of the Company's global lease portfolio represents leases of real estate, such as manufacturing facilities, warehouses, and office buildings, while the remainder represents leases of personal property, such as vehicle leases, manufacturing and IT equipment. Most of the leases are operating leases with options to renew, with renewal terms that can extend the lease term from 1 to 5 years. The option to renew is included in the lease term if it is reasonably certain that the Company will exercise that option. Certain leases also include options to terminate or purchase the leased asset. The depreciable life of assets and leasehold improvements are limited by the expected lease term, unless there is a transfer of title or purchase option that is reasonably certain of exercise. The amount recognized in lease assets and liabilities for lease arrangements that include an option for renewal or early termination that is reasonably certain of being exercised is immaterial. The Company's lease agreements do not contain any material residual value guarantee or material restrictive covenants. The Company's policy is to account for the lease and non-lease components as a single lease component for all asset classes.

ASC 842 requires that the rate implicit in the lease be used if readily determinable. Generally, implicit rates are not readily determinable in the Company's contracts and the incremental borrowing rate is used for each lease arrangement. The incremental borrowing rates are determined using rates specific to the term of the lease, economic environments where lease activity is concentrated, value of lease portfolio, and assuming full collateralization of the loans.

All leases with an initial term of 12 months or less that do not include an option to extend or purchase the underlying asset that the Company is reasonably certain to exercise ("short-term leases") are not recorded on the consolidated balance sheet and lease expense is recognized on a straight-line basis over the lease term.

In the three and six months ended June 30, 2019, the Company recorded operating lease cost of $6 million and $13 million, respectively, reflected in Selling, general and administrative expenses in the Condensed Consolidated Statement of Operations. The finance lease cost including amortization of leased assets and interest on lease liabilities was less than $1 million in the six months ended June 30, 2019. Variable costs for the six months ended June 30, 2019 are immaterial, and the Company does not have sublease income or gains/losses on sale leaseback transactions.

The following table presents the maturity of lease liabilities as of June 30, 2019:

(in millions)	Operating Leases

The operating cash flows for operating leases were $12 million for the six months ended June 30, 2019.

As of June 30, 2019, the operating and finance leases that the Company signed but have not yet commenced are immaterial.

(18)  Contingencies

The Company's environmental and product liability contingencies are discussed separately below. In the normal course of business, the Company is also party to various other commercial and legal claims, actions and complaints, including matters involving warranty claims, intellectual property claims, general liability and various other risks. It is not possible to predict with certainty whether or not the Company will ultimately be successful in any of these other commercial and legal matters or, if not, what the impact might be. The Company's management does not expect that an adverse outcome in any of these other commercial and legal claims, actions and complaints will have a material adverse effect on the Company's results of operations, financial position or cash flows, although it could be material to the results of operations in a particular quarter.

Environmental

The Company and certain of its current and former direct and indirect corporate predecessors, subsidiaries and divisions have been identified by the United States Environmental Protection Agency and certain state environmental agencies and private parties as potentially responsible parties (“PRPs”) at various hazardous waste disposal sites under the Comprehensive Environmental Response, Compensation and Liability Act (“Superfund”) and equivalent state laws. The PRPs may currently be liable for the cost of clean-up and other remedial activities at 27 such sites. Responsibility for clean-up and other remedial activities at a Superfund site is typically shared among PRPs based on an allocation formula.

The Company believes that none of these matters, individually or in the aggregate, will have a material adverse effect on its results of operations, financial position or cash flows. Generally, this is because either the estimates of the maximum potential liability at a site are not material or the liability will be shared with other PRPs, although no assurance can be given with respect to the ultimate outcome of any such matter.

The Company has an accrual for environmental liabilities of $8 million and $9 million as of June 30, 2019 and December 31, 2018, respectively. This accrual is based on information available to the Company (which in most cases includes an estimate of allocation of liability among PRPs; the probability that other PRPs, many of whom are large, solvent public companies, will fully pay the cost apportioned to them; currently available information from PRPs and/or federal or state environmental agencies concerning the scope of contamination and estimated remediation and consulting costs; and remediation alternatives).

26

Asbestos-related Liability

Like many other industrial companies that have historically operated in the United States, the Company, or parties that the Company is obligated to indemnify, continues to be named as one of many defendants in asbestos-related personal injury actions. The Company vigorously defends against these claims, and has been successful in obtaining the dismissal of the majority of the claims asserted against it without any payment. Due to the nature of the fibers used in certain types of automotive products, the encapsulation of the asbestos, and the manner of the products’ use, the Company believes that these products were and are highly unlikely to cause harm.  Furthermore, the useful life of nearly all of these products expired many years ago. The Company likewise expects that no payment on these claims will be made by the Company or its insurance carriers in the vast majority of current and future asbestos-related claims. 

The Company’s asbestos-related claims activity during the six months ended June 30, 2019 and 2018 is as follows:

	2019		2018
Beginning Claims January 1	8,598		9,225
New Claims Received	1,111		1,020
Dismissed Claims	(793	)	(786	)
Settled Claims	(154	)	(189	)
Ending Claims June 30	8,762		9,270

From the mid-2000s through June 30, 2019 and December 31, 2018, the Company incurred $596 million and $574 million, respectively, in asbestos-related claim resolution costs (including settlement payments and judgments) and associated defense costs. During the six months ended June 30, 2019 and 2018, the Company paid $15 million and $28 million, respectively, in asbestos-related claim resolution costs and associated defense costs. These gross payments are before tax benefits and any potential insurance receipts. Asbestos-related claim resolution costs and associated defense costs are reflected in the Company's operating cash flows.

The Company reviews, on an ongoing basis, its own experience in handling asbestos-related claims and trends affecting asbestos-related claims in the U.S. tort system generally, for the purposes of assessing the value of pending asbestos-related claims and the number and value of those that may be asserted in the future, as well as potential recoveries from the Company’s insurance carriers with respect to such claims and defense costs. The Company has accrued estimated amounts in its consolidated financial statements on account of asbestos-related claims that have been asserted but not yet resolved and for claims that have not yet been asserted. The Company's estimate of asbestos-related claim resolution costs and associated defense costs is not discounted to present value and includes an estimate of liability for potential future claims not yet asserted through December 31, 2064 with a runoff through 2074. The Company currently believes that December 31, 2074 is a reasonable assumption as to the last date on which it is likely to have resolved all asbestos-related claims, based on the nature and useful life of the Company’s products and the likelihood of incidence of asbestos-related disease in the U.S. population generally. As of June 30, 2019 and June 30, 2018, the Company’s reasonable best estimate of the aggregate liability for both asbestos-related claims asserted but not yet resolved and potential asbestos-related claims not yet asserted, including estimated defense costs, is as follows:

(in millions)	2019			2018
Beginning asbestos liability as of January 1	$	805		$	828
Claim resolution costs and associated defense costs	(22		)	(28		)
Ending asbestos liability as of June 30	$	783		$	800

27

The Company’s estimate of the claim resolution costs and associated defense costs for asbestos-related claims asserted but not yet resolved and potential claims not yet asserted is its reasonable best estimate of such costs. Such estimate is subject to numerous uncertainties. These include future legislative or judicial changes affecting the U.S. tort system, bankruptcy proceedings involving one or more co-defendants, the impact and timing of payments from bankruptcy trusts that currently exist and those that may exist in the future, disease emergence and associated claim filings, the impact of future settlements or significant judgments, changes in the medical condition of claimants, changes in the treatment of asbestos-related disease, and any changes in settlement or defense strategies. The balances recorded for asbestos-related claims are based on the best available information and assumptions that the Company believes are reasonable, including as to the number of future claims that may be asserted, the percentage of claims that may result in a payment, the average cost to resolve such claims, and potential defense costs. The Company has concluded that it is reasonably possible that it may incur additional losses through 2074 for asbestos-related claims, in addition to amounts recorded, of up to approximately $100 million as of June 30, 2019 and December 31, 2018. The various assumptions utilized in arriving at the Company’s estimate may also change over time, and the Company’s actual liability for asbestos-related claims asserted but not yet resolved and those not yet asserted may be higher or lower than the Company’s estimate as a result of such changes.

The Company has certain insurance coverage applicable to asbestos-related claims including primary insurance and excess insurance coverage.  Prior to June 2004, claim resolution costs and defense costs associated with all asbestos-related claims were paid by the Company's primary layer insurance carriers under a series of interim funding arrangements. In June 2004, primary layer insurance carriers notified the Company of the alleged exhaustion of their policy limits. A declaratory judgment action was filed in January 2004 in the Circuit Court of Cook County, Illinois by Continental Casualty Company and related companies against the Company and certain of its historical general liability insurance carriers. The Cook County court has issued a number of interim rulings, and discovery is continuing in this proceeding. The Company is vigorously pursuing the litigation against all insurance carriers that continue to be parties to it, which currently includes excess insurance carriers, as well as pursuing settlement discussions with its insurance carriers where appropriate. The Company has entered into settlement agreements with certain of its insurance carriers, resolving such insurance carriers’ coverage disputes through the insurance carriers’ agreement to pay specified amounts to the Company, either immediately or over a specified period. Through June 30, 2019 and December 31, 2018, the Company received $272 million and $271 million, respectively, in cash and notes from insurance carriers on account of asbestos-related claim resolution costs and associated defense costs.

As of June 30, 2019 and December 31, 2018, the Company estimates that it has $386 million in aggregate insurance coverage available with respect to asbestos-related claims, and their associated defense costs. The Company has recorded this insurance coverage as a long-term receivable for asbestos-related claim resolution costs and associated defense costs that have been incurred, less cash and notes received, and remaining limits as a deferred insurance asset with respect to liabilities recorded for potential future costs for asbestos-related claims. The Company has determined the amount of that estimate by taking into account the remaining limits of the insurance coverage, the number and amount of potential claims from co-insured parties, potential remaining recoveries from insolvent insurance carriers, the impact of previous insurance settlements, and coverage available from solvent insurance carriers not party to the coverage litigation. The Company’s estimated remaining insurance coverage relating to asbestos-related claims and their associated defense costs is the subject of disputes with its insurance carriers, substantially all of which are being adjudicated in the Cook County insurance litigation. The Company believes that its insurance receivable is probable of collection notwithstanding those disputes based on, among other things, the arguments made by the insurance carriers in the Cook County litigation and evaluation of those arguments by the Company and its counsel, the case law applicable to the issues in dispute, the rulings to date by the Cook County court, the absence of any credible evidence alleged by the insurance carriers that they are not liable to indemnify the Company, and the fact that the Company has recovered a substantial portion of its insurance coverage, 

28

$272 million, through June 30, 2019, from its insurance carriers under similar policies. However, the resolution of the insurance coverage disputes, and the number and amount of claims on our insurance from co-insured parties, may increase or decrease the amount of such insurance coverage available to the Company as compared to the Company’s estimate.

The amounts recorded in the Condensed Consolidated Balance Sheets respecting asbestos-related claims are as follows:

	June 30,		December 31,
(in millions)	2019		2018
Assets:
Other long-term asbestos-related insurance receivables	$	324	$	303
Deferred asbestos-related insurance asset	$	62	$	83
Total insurance assets	$	386	$	386
Liabilities:
Accounts payable and accrued expenses	$	49	$	50
Other non-current liabilities	734		755
Total accrued liabilities	$	783	$	805

On July 31, 2018, the Division of Enforcement of the Securities and Exchange Commission ("SEC") informed the Company that it is conducting an investigation related to the Company's accounting for asbestos-related claims not yet asserted. The Company is fully cooperating with the SEC in connection with its investigation.

(19) Restructuring

In the third quarter of 2017, the Company initiated actions within its Engine segment designed to improve future profitability and competitiveness and started exploring strategic options for the non-core product lines. As a continuation of these actions, the Company recorded restructuring expense of $4 million and $11 million during the three and six months ended June 30, 2019, and $28 million and $33 million during the three and six months ended June 30, 2018, respectively, primarily related to professional fees and employee termination benefits. Additionally, in the first quarter of 2019, the Company initiated a separate voluntary termination program in the Engine segment and recorded restructuring expense of $7 million and $11 million in the three and six months ended June 30, 2019, respectively. The Company will continue its plan to improve the future profitability and competitiveness of its business in the Engine segment. These actions may result in the recognition of additional restructuring charges that could be material.

The Company recorded restructuring expense of $3 million in the six months ended June 30, 2019 related to Corporate restructuring activities.

Additionally, the Company recorded restructuring expense of $3 million and $6 million in the three and six months ended June 30, 2018, respectively, in the Drivetrain segment primarily related to manufacturing footprint rationalization activities.

Estimates of restructuring expense are based on information available at the time such charges are recorded. Due to the inherent uncertainty involved in estimating restructuring expenses, actual amounts paid for such activities may differ from amounts initially recorded.

(20) Earnings Per Share

The Company presents both basic and diluted earnings per share of common stock (“EPS”). Basic EPS is calculated by dividing net earnings attributable to the Company by the weighted average shares of common stock outstanding during the reporting period. Diluted EPS is calculated by dividing net earnings attributable to the Company by the weighted average shares of common stock and common equivalent stock outstanding during the reporting period.

The dilutive impact of stock-based compensation is calculated using the treasury stock method. The treasury stock method assumes that the Company uses the assumed proceeds from the exercise of awards to repurchase common stock at the average market price during the period. The assumed proceeds under the treasury stock method include the purchase price that the grantee will pay in the future and compensation cost for future service that the Company has not yet recognized. The dilutive effects of performance-based stock awards described in the Note 14, "Stock-Based Compensation," to the Condensed Consolidated Financial Statements are included in the computation of diluted earnings per share at the level the related performance criteria are met through the respective balance sheet date.

(21) Reporting Segments

The Company's business is comprised of two reporting segments: Engine and Drivetrain. These segments are strategic business groups that are managed separately as each represents a specific grouping of related automotive components and systems.

The Company allocates resources to each segment based upon the projected after-tax return on invested capital ("ROIC") of its business initiatives. Adjusted EBIT is comprised of earnings before interest, income taxes and noncontrolling interest (“EBIT") adjusted for restructuring, goodwill impairment charges, affiliates' earnings and other items not reflective of on-going operating income or loss ("Adjusted EBIT"). ROIC is comprised of Adjusted EBIT after deducting notional taxes compared to the projected average capital investment required.

Adjusted EBIT is the measure of segment income or loss used by the Company. The Company believes Adjusted EBIT is most reflective of the operational profitability or loss of our reporting segments. The following tables show segment information and Adjusted EBIT for the Company's reporting segments.

(22) Recent Transactions

Romeo Power Technology

In May 2019, the Company invested $50 million, $46 million of which was paid in the second quarter of 2019, in exchange for a 20% equity interest in Romeo Power Technology ("Romeo") , a technology-leading battery module and pack supplier. The Company accounts for this investment in Series A-1 Preferred Stock of Romeo under the measurement alternative in ASC 321, "Investments - Equity Securities" for equity investments without a readily determinable fair value. Such investments are measured at cost, less any impairment, plus or minus changes resulting from observable price changes in orderly transactions for an identical or similar investment of the same issuer. Additionally, the Company and Romeo will form a new joint venture where the Company will own 60% interest. The joint venture will focus on producing battery module and pack technology.

32

Rinehart Motion Systems LLC and AM Racing LLC

On January 2, 2019, the Company acquired Rinehart Motion Systems LLC and AM Racing LLC, two established companies in the specialty electric and hybrid propulsion market, for approximately $15 million, of which $10 million was paid in the first quarter of 2019 and the remaining $5 million will be paid upon satisfaction of certain conditions.

The Company created Cascadia Motion LLC ("Cascadia Motion") to combine assets and operations of these two acquired companies. Based in Oregon, Cascadia Motion specializes in design, development and production of hybrid and electric propulsion solutions for prototype and low-volume production applications. It allows the Company to offer design, development and production of full electric and hybrid propulsion systems for niche and low-volume manufacturing applications.

In connection with the acquisition, the Company recognized intangible assets of $5 million, goodwill of $7 million within the Drivetrain reporting segment, and other assets and liabilities of $2 million to reflect the preliminary fair value of the assets acquired and liabilities assumed. The intangible assets will be amortized over a period of 2 to 15 years. Various valuation techniques were used to determine the fair value of the intangible assets, with the primary techniques being forms of the income approach, which use significant unobservable inputs, or Level 3 inputs, as defined by the fair value hierarchy. Under these valuation approaches, the Company is required to make estimates and assumptions about sales, operating margins, growth rates, royalty rates and discount rates based on budgets, business plans, economic projections, anticipated future cash flows and marketplace data. Due to the nature of the transaction, goodwill is not deductible for tax purposes.

The Company is in the process of finalizing all purchase accounting adjustments related to the acquisition of Cascadia Motion. Certain estimated values for the acquisition, including goodwill, intangible assets and deferred taxes, are not yet finalized, and the preliminary purchase price allocations are subject to change as the Company completes its analysis of the fair value as of the date of acquisition.

Due to its insignificant size relative to the Company, supplemental pro forma financial information of the combined entity for the current and prior reporting period is not provided.

(23) Assets and Liabilities Held For Sale

In 2017, the Company started exploring strategic options for non-core product lines in the Engine segment, launched an active program to locate a buyer and initiated all other actions required to complete the plan to sell and exit the non-core pipe and thermostat product lines. During 2018, the Company continued its marketing efforts with interested parties and engaged in active discussions with these parties. In December 2018, after finalizing negotiations regarding various aspects of the sale, the Company entered into a definitive agreement to sell its thermostat product lines for approximately $28 million subject to customary adjustments. All closing conditions were satisfied, and the sale was closed on April 1, 2019. The Company received cash proceeds of $27 million in the six months ended June 30, 2019. Additionally, during the six months ended June 30, 2019, the Company entered into agreements to transition its pipes product lines to multiple buyers, for inconsequential proceeds. Based on the cash proceeds in conjunction with the closing of the transaction to sell the thermostat product lines, the Company determined no additional gain or loss on sale was required during the six months ended June 30, 2019. During the six months ended June 30, 2019, the assets and liabilities were removed from the Condensed Consolidated Balance Sheet. The business did not meet the criteria to be classified as a discontinued operation.

The Company is in the process of finalizing all purchase price adjustments related to the sale of non-core product lines. Subsequent adjustments may be necessary based on the finalization of this process.

The Company operates manufacturing facilities serving customers in Europe, the Americas and Asia and is an original equipment supplier to every major automotive OEM in the world.

The Company's products fall into two reporting segments: Engine and Drivetrain. The Engine segment's products include turbochargers, timing devices and chains, emissions systems and thermal systems. The Drivetrain segment's products include transmission components and systems, all-wheel drive torque transfer systems and rotating electrical devices.

RESULTS OF OPERATIONS

Three Months Ended June 30, 2019 vs. Three Months Ended June 30, 2018

Net sales for the three months ended June 30, 2019 totaled $2,551 million, a 5.3% decrease from the three months ended June 30, 2018. Excluding the impact of weaker foreign currencies, primarily the Euro, Chinese Renminbi and Korean Won, and the net impact of acquisitions and divestitures, net sales decreased approximately 0.3%.

Cost of sales as a percentage of net sales was 79.9% in the three months ended June 30, 2019 compared to 78.5% in the three months ended June 30, 2018. Gross profit and gross margin were $513 million and 20.1% in the three months ended June 30, 2019 compared to $580 million and 21.5% in the three months ended June 30, 2018. The reduction of gross margin is primarily due to the impact of lower revenue, cost of recently enacted tariffs and supplier cost reductions not keeping pace with normal customer price deflation. The Company's material cost of sales was 55.6% and 54.1% of net sales in the three months ended June 30, 2019 and 2018, respectively. The Company's remaining cost to convert raw material to finished product was comparable to the three months ended June 30, 2018.

Selling, general and administrative ("SG&A") expenses for the three months ended June 30, 2019 decreased $25 million to $212 million as compared to $237 million for the three months ended June 30, 2018, primarily due to lower compensation expenses. SG&A as a percentage of net sales was 8.3% and 8.8% for the three months ended June 30, 2019 and 2018, respectively. R&D expenses, which are included in SG&A expenses, for the three months ended June 30, 2019, increased $1 million to $113 million as compared to $112 million for the three months ended June 30, 2018. R&D as a percentage of net sales was 4.4% and 4.2% for the three months ended June 30, 2019 and 2018, respectively.

Other expense, net of $16 million for the three months ended June 30, 2019 includes $13 million of restructuring expense primarily related to actions within the Engine segment designed to improve future profitability and competitiveness, and $5 million of expenses related to the Company's review of strategic acquisition targets, including the 20% equity interest in Romeo Power Technology. The Company will continue its plan to improve the future profitability and competitiveness of its business in the Engine segment. These actions may result in the recognition of additional restructuring charges that could be material.

35

Other expense, net of $30 million for the three months ended June 30, 2018 includes $31 million of restructuring expense primarily related to actions within the Engine segment designed to improve future profitability and competitiveness and $1 million of expenses primarily related to divestiture activities for the non-core pipes and thermostat product lines.

Equity in affiliates’ earnings of $9 million decreased $4 million as compared with the three months ended June 30, 2018 due to lower industry volumes.

Interest expense of $14 million was relatively flat from the three months ended June 30, 2018.

Other postretirement expense (income) of $27 million increased $29 million as compared with the three months ended June 30, 2019. The Company settled approximately $50 million of its pension projected benefit obligation by liquidating approximately $50 million in plan assets through a lump-sum pension de-risking disbursement made to an insurance company. Pursuant to this agreement, the insurance company unconditionally and irrevocably guarantees all future payments to certain participants that were receiving payments from the U.S. pension plan. The insurance company assumes all investment risk associated with the assets that were delivered as part of this transaction. Additionally, during the three months ended June 30, 2019, the Company discharged certain U.S. pension plan obligations by making lump-sum payments of $13 million to former employees of the Company. As a result, the Company settled $63 million of projected pension obligation by liquidating of pension plan assets and recorded a non-cash settlement loss of $26 million related to the accelerated recognition of unamortized losses.

The Company's effective tax rate for the six months ended June 30, 2019 was 31.7%. This rate includes reductions of income tax expenses of $7 million related to restructuring expense, and $5 million related to other one-time adjustments. This rate also includes an increase in income tax expense of $22 million due to the U.S. Department of the Treasury’s issuance of the final regulations in the first quarter of 2019 related to the calculation of the one-time transition tax. Excluding the impact of these non-comparable items, the Company estimated its annual effective tax rate associated with ongoing operations to be approximately 27% for the year ending December 31, 2019.

The Company's effective tax rate for the first six months ended June 30, 2018 was 19.4%. This rate includes income tax expense of $1 million related to a commercial settlement gain and reductions of income tax expense of $8 million which is associated with restructuring expense, $13 million related to adjustments to measurement period provisional estimates associated with the Tax Cuts and Jobs Act of 2017 (the "Tax Act"), $21 million related to an increase to our deferred tax asset due to the Company's ability to record a tax benefit for certain foreign tax credits now available due to actions the Company took in the second quarter, and $10 million for other one-time tax adjustments.

Six Months Ended June 30, 2019 vs. Six Months Ended June 30, 2018

Net sales for the six months ended June 30, 2019 totaled $5,117 million, a 6.6% decrease from the six months ended June 30, 2018. Excluding the impact of weaker foreign currencies, primarily the Euro, Chinese Renminbi and Korean Won, and the net impact of acquisitions and divestitures, net sales decreased approximately 1.8%.

Cost of sales as a percentage of net sales was 79.8% in the six months ended June 30, 2019 compared to 78.6% in the six months ended June 30, 2018. Gross profit and gross margin were $1,032 million and 20.2% in the six months ended June 30, 2019 compared to $1,171 million and 21.4% in the six months ended June 30, 2018. The reduction of gross margin is primarily due to the impact of lower revenue, cost of recently enacted tariffs and supplier cost reductions not keeping pace with normal customer price deflation. The Company's material cost of sales was 55.4% and 54.6% of net sales in the six months ended June 30, 2019 and 2018, respectively. The Company's remaining cost to convert raw material to finished product was comparable to the six months ended June 30, 2018.

Selling, general and administrative ("SG&A") expenses for the six months ended June 30, 2019 decreased $52 million to $438 million as compared to $490 million for the six months ended June 30, 2018, primarily due to lower research and development ("R&D") and compensation expenses. SG&A as a percentage of net sales was 8.6% and 8.9% for the six months ended June 30, 2019 and 2018, respectively. R&D expenses, which are included in SG&A expenses, for the six months ended June 30, 2019, decreased $12 million to $217 million as compared to $229 million for the six months ended June 30, 2018. R&D as a percentage of net sales was 4.2% for both of the six months ended June 30, 2019 and 2018.

Other expense, net of $45 million for the six months ended June 30, 2019 includes $27 million of restructuring expense primarily related to actions within the Engine segment designed to improve future profitability and competitiveness, $14 million of expenses related to the receipt of a final unfavorable arbitration decision associated with the resolution of a matter related to a previous acquisition, and $6 million of expenses related to the Company's review of strategic acquisition targets, including the 20% equity interest in Romeo Power Technology. The Company will continue its plan to improve the future profitability and competitiveness of its business in the Engine segment. These actions may result in the recognition of additional restructuring charges that could be material.

Other expense, net of $35 million for the six months ended June 30, 2018 includes $39 million of restructuring expense primarily related to actions within the Engine segment designed to improve future profitability and competitiveness and $3 million of expenses primarily related to divestiture activities for

37

the non-core pipes and thermostat product lines and a gain of $4 million related to the settlement of a commercial contract for an entity acquired in the 2015 Remy acquisition.

Equity in affiliates’ earnings of $18 million decreased $5 million as compared with the six months ended June 30, 2018 due to lower industry volumes.

Interest expense of $28 million decreased $3 million as compared with the six months ended June 30, 2018, primarily due to lower debt and cross-currency swaps executed in 2018, offset by a decrease in capitalized interest. See Note 12, "Financial Instruments," to the Condensed Consolidated Financial Statements for further discussion of the cross-currency swaps.

Other postretirement expense (income) of $27 million increased $32 million as compared with the six months ended June 30, 2019. The Company settled approximately $50 million of its pension projected benefit obligation by liquidating approximately $50 million in plan assets through a lump-sum pension de-risking disbursement made to an insurance company.

Three Months Ended June 30, 2019 vs. Three Months Ended June 30, 2018

The Engine segment net sales decreased $105 million, or 6.3%, from the three months ended June 30, 2018. Excluding the impact of weaker foreign currencies, primarily the Euro, Chinese Renminbi, and Korean Won, and the net impact of acquisitions and divestitures, net sales decreased approximately 0.4% from the three months ended June 30, 2018, due to a decline in industry volumes. The Engine segment Adjusted EBIT margin was 15.9% in the three months ended June 30, 2019, down from 16.7% in the three months ended June 30, 2018 primarily due to industry volume declines and supplier cost reductions not keeping pace with normal customer price deflation.

The Drivetrain segment net sales decreased $36 million, or 3.5%, from the three months ended June 30, 2018. Excluding the impact of weaker foreign currencies, primarily the Euro, Chinese Renminbi, and Korean Won, net sales increased approximately 0.2% from the three months ended June 30, 2018, primarily due to higher net new business. The Drivetrain segment Adjusted EBIT margin was 10.2% in the three months ended June 30, 2019 down from 11.2% in the three months ended June 30, 2018, primarily due to higher research and development spending and startup costs for launches.

Six Months Ended June 30, 2019 vs. Six Months Ended June 30, 2018

The Engine segment net sales decreased $223 million, or 6.6%, from the six months ended June 30, 2018. Excluding the impact of weaker foreign currencies, primarily the Euro, Chinese Renminbi, and Korean Won, and the net impact of acquisitions and divestitures, net sales decreased approximately 1.1% from the six months ended June 30, 2018, due to a decline in industry volumes. The Engine segment Adjusted EBIT margin was 15.5% in the six months ended June 30, 2019, down from 16.5% in the six months ended June 30, 2018 primarily due to industry volume declines and supplier cost reductions not keeping pace with normal customer price deflation.

The Drivetrain segment net sales decreased $137 million, or 6.5%, from the six months ended June 30, 2018. Excluding the impact of weaker foreign currencies, primarily the Euro, Chinese Renminbi and Korean Won, net sales decreased approximately 2.8% from the six months ended June 30, 2018,

40

primarily due to a decline in industry volumes. The Drivetrain segment Adjusted EBIT margin was 10.5% in the six months ended June 30, 2019 down from 11.2% in the six months ended June 30, 2018, primarily due to industry volume declines, higher research and development spending and startup costs for launches.

Outlook

Based on the mid-point of guidance, the Company expects a modest year over year decline in revenue, excluding the impact of foreign currencies and the net impact of acquisitions and divestitures. Net new business-related sales growth is expected to partially offset the impact of the declining global industry production expected in 2019.

The Company maintains a positive long-term outlook for its global business and is committed to new product development and strategic capital investments to enhance its product leadership strategy. The several trends that are driving the Company's long-term growth are expected to continue, including increased turbocharger adoption in North America and Asia, the increased adoption of automated transmissions in Europe and Asia Pacific, and the move to variable-cam timing in Europe and Asia Pacific. The Company's long-term growth is also expected to ultimately benefit from the adoption of product offerings for hybrid and electric vehicles.

FINANCIAL CONDITION AND LIQUIDITY

The Company maintains various liquidity sources including cash and cash equivalents and the unused portion of its multi-currency revolving credit agreement. At June 30, 2019, the Company had $710 million of cash, of which $599 million of cash is held by our subsidiaries outside of the United States. Cash held by these subsidiaries is used to fund foreign operational activities and future investments, including acquisitions.

The vast majority of cash held outside the United States is available for repatriation. The Tax Act reduced the U.S. federal corporate tax rate from 35 percent to 21 percent and required companies to pay a one-time transition tax on earnings of certain foreign subsidiaries that were previously tax deferred. As of January 1, 2018, funds repatriated from foreign subsidiaries will generally no longer be taxable for U.S. federal tax purposes. In light of the treatment of foreign earnings under the Tax Act, the Company recorded a liability for the U.S. federal and applicable state income tax liabilities calculated under the provisions of the deemed repatriation of foreign earnings. A deferred tax liability has been recorded for substantially all estimated legally distributable foreign earnings. The Company uses its U.S. liquidity primarily for various corporate purposes, including but not limited to debt service, share repurchases, dividend distributions and other corporate expenses.

The Company has a $1.2 billion multi-currency revolving credit facility, which includes a feature that allows the Company's facility to be increased to $1.5 billion with approval of the bank group. The facility provides for borrowings through June 29, 2022. The Company has one key financial covenant as part of the credit agreement which is a debt to EBITDA ("Earnings Before Interest, Taxes, Depreciation and Amortization") ratio. The Company was in compliance with the financial covenant at June 30, 2019 and expects to remain compliant in future periods. At June 30, 2019 and December 31, 2018, the Company had no outstanding borrowings under this facility.

The Company's commercial paper program allows the Company to issue short-term, unsecured commercial paper notes up to a maximum aggregate principal amount outstanding of $1.2 billion. Under this program, the Company may issue notes from time to time and use the proceeds for general corporate purposes. The Company had no outstanding borrowings under this program as of June 30, 2019 and December 31, 2018.

41

The total current combined borrowing capacity under the multi-currency revolving credit facility and commercial paper program cannot exceed $1.2 billion.

In addition to the credit facility, the Company's universal shelf registration provides the ability to issue various debt and equity instruments subject to market conditions.

On February 6, 2019 and April 25, 2019, the Company’s Board of Directors declared quarterly cash dividends of $0.17 per share of common stock. These dividends were paid on March 15, 2019 and June 17, 2019, respectively.

At June 30, 2019, the Company had a credit rating of BBB+ from both Standard & Poor's and Fitch Ratings and Baa1 from Moody's. The current outlook from Standard & Poor's, Moody's, and Fitch Ratings is stable. None of the Company's debt agreements requires accelerated repayment in the event of a downgrade in credit ratings.

Net cash provided by operating activities increased $162 million to $467 million in the first six months of 2019 from $305 million in the first six months of 2018. The cash increase from operating activities of $162 million primarily reflects favorable changes in working capital, offset by lower net earnings adjusted for non-cash charges to operations.

Net cash used in investing activities increased $10 million to $277 million in the first six months of 2019 from $267 million in the first six months of 2018. This increase is primarily due to the equity investment in Romeo Power Technology, the acquisition of Rinehart Motion Systems LLC and AM Racing LLC, offset by lower capital expenditures, including tooling outlays, and proceeds from the sale of the non-core pipe and thermostat product lines.

Net cash used in financing activities increased $3 million to $218 million in the first six months of 2019 from $215 million in the first six months of 2018. This increase is primarily driven by higher net debt repayments, offset by lower share repurchases.

The Company believes that the combination of cash balances, cash from operations, available credit facilities, and the universal shelf registration capacity will be sufficient to satisfy its cash needs for current level of operations, planned operations for the foreseeable future and current share repurchase program. The Company will continue to balance its needs for internal growth, external growth, the return of capital to stockholders, debt reduction and cash conservation.

CONTINGENCIES

The Company's environmental and product liability contingencies are discussed separately below. In the normal course of business, the Company is also party to various other commercial and legal claims, actions and complaints, including matters involving warranty claims, intellectual property claims, general liability and various other risks. It is not possible to predict with certainty whether or not the Company will ultimately be successful in any of these other commercial and legal matters or, if not, what the impact might be. The Company's management does not expect that an adverse outcome in any of these other commercial and legal claims, actions and complaints will have a material adverse effect on the Company's results of operations, financial position or cash flows, although it could be material to the results of operations in a particular quarter.

Environmental

The Company and certain of its current and former direct and indirect corporate predecessors, subsidiaries and divisions have been identified by the United States Environmental Protection Agency and certain state environmental agencies and private parties as potentially responsible parties (“PRPs”)

42

at various hazardous waste disposal sites under the Comprehensive Environmental Response, Compensation and Liability Act (“Superfund”) and equivalent state laws. The PRPs may currently be liable for the cost of clean-up and other remedial activities at 27 such sites. Responsibility for clean-up and other remedial activities at a Superfund site is typically shared among PRPs based on an allocation formula.

The Company believes that none of these matters, individually or in the aggregate, will have a material adverse effect on its results of operations, financial position or cash flows. Generally, this is because either the estimates of the maximum potential liability at a site are not material or the liability will be shared with other PRPs, although no assurance can be given with respect to the ultimate outcome of any such matter.

See  Note 18, - "Contingencies," to the Condensed Consolidated Financial Statements for further details and information respecting the Company’s environmental liability.

Asbestos-related Liability

Like many other industrial companies that have historically operated in the United States, the Company, or parties the Company is obligated to indemnify, continues to be named as one of many defendants in asbestos-related personal injury actions. The Company has an estimated liability of $783 million as of June 30, 2019 for asbestos-related claims and associated costs through 2074, which is the last date by which the Company currently estimates it is likely to have resolved all asbestos-related claims. The Company additionally estimates that, as of June 30, 2019, it has aggregate insurance coverage available in the amount of $386 million to satisfy asbestos-related claims and associated defense costs.  See  Note 18 - "Contingencies," to the Condensed Consolidated Financial Statements for further details and information respecting the Company’s asbestos-related liability and corresponding insurance asset.

New Accounting Pronouncements

See Note 2 - "New Accounting Pronouncements," to the Condensed Consolidated Financial Statements for a detailed description of new applicable accounting pronouncements.

Item 3.Quantitative and Qualitative Disclosures About Market Risk

There have been no material changes to the information concerning our exposures to interest rate risk or commodity price risk as stated in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018.

Foreign currency exchange rate risk is the risk that the Company will incur economic losses due to adverse changes in foreign currency exchange rates. Currently, the Company's most significant currency exposures relate to the Chinese Renminbi, the Euro, the Hungarian Forint, the Japanese Yen, the Mexican Peso, the Swedish Krona and the South Korean Won. The Company mitigates its foreign currency exchange rate risk by establishing local production facilities and related supply chain participants in the markets it serves, by invoicing customers in the same currency as the source of the products and by funding some of its investments in foreign markets through local currency loans. The Company also monitors its foreign currency exposure in each country and implement strategies to respond to changing economic and political environments. The depreciation of the British Pound post the United Kingdom's 2016 vote to leave the European Union and planned implementation actions are not expected to have a significant impact on the Company since net sales from the United Kingdom represent less than 2% of the Company's net sales in 2018. In addition, the Company periodically enters into forward currency contracts in order to reduce exposure to exchange rate risk related to transactions denominated in currencies other than the functional currency.

43

The foreign currency translation adjustment loss of $13 million and $22 million for the three and six months ended June 30, 2019, and loss of $146 million and $81 million for the three and six months ended June 30, 2018, contained within the Company's Condensed Consolidated Statements of Comprehensive Income (Loss) represent the foreign currency translational impacts of converting its non-U.S. dollar subsidiaries' financial statements to the Company’s reporting currency (U.S. Dollar). The foreign currency translation adjustment loss of $13 million in the three months ended June 30, 2019 was primarily due to the impact of a strengthening U.S. dollar against Chinese Renminbi and Korean Won, which both increased approximately 2% from March 31, 2019, partially offset by a weakening U.S. dollar against the Euro, which decreased approximately 1% from March 31, 2019. The foreign currency translation adjustment loss of $22 million in the six months ended June 30, 2019 was primarily due to the impact of a strengthening U.S. dollar against the Euro and Korean Won, which increased approximately 1% and 4% from December 31, 2018, respectively. The foreign currency translation adjustment loss of $146 million and $81 million in the three and six months ended June 30, 2018 was primarily due to the impact of a strengthening U.S. dollar against the Euro, which increased approximately 6% and 3% from March 31, 2018 and December 31, 2017, respectively.

Item 4.Controls and Procedures

The Company maintains disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) that are designed to ensure that information required to be disclosed by the Company in the reports that it files or submits under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported, within the time periods specified in the SEC's rules and forms. Under the supervision and with the participation of the Company’s management, including the Company’s Chief Executive Officer and Chief Financial Officer, the Company has evaluated the effectiveness of the design and operation of its disclosure controls and procedures as of the end of the period covered by this report. Based on such evaluation, the Company’s Chief Executive Officer and Chief Financial Officer have concluded that these controls and procedures are effective. There have been no changes in internal control over financial reporting that occurred during the period covered by this report that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

44

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

The Company is subject to a number of claims and judicial and administrative proceedings (some of which involve substantial amounts) arising out of the Company’s business or relating to matters for which the Company may have a contractual indemnity obligation. See Note 18 - "Contingencies," to the Condensed Consolidated Financial Statements of this Quarterly Report on Form 10-Q for a discussion of environmental, asbestos-related liability and other litigation, which is incorporated herein by reference.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

The Company's Board of Directors authorized the purchase of up to 79.6 million shares of the Company's common stock in the aggregate. As of June 30, 2019, the Company had repurchased 75.4 million shares in the aggregate under the common stock repurchase program. All shares purchased under this authorization have been and will continue to be repurchased in the open market at prevailing prices and at times and in amounts to be determined by management as market conditions and the Company's capital position warrant. The Company may use Rule 10b5-1 and 10b-18 plans to facilitate share repurchases. Repurchased shares will be deemed common stock held in treasury and may subsequently be reissued for general corporate purposes.

Employee transactions include restricted stock withheld to offset statutory minimum tax withholding that occurs upon vesting of restricted stock. The BorgWarner Inc. 2014 Stock Incentive Plan, as amended, and the BorgWarner Inc. 2018 Stock Incentive Plan provide that the withholding obligations relating to an award be settled by the Company retaining stock that is part of the award. Withheld shares will be deemed common stock held in treasury and may subsequently be reissued for general corporate purposes.

The following table provides information about the Company's purchases of its equity securities that are registered pursuant to Section 12 of the Exchange Act during the quarter ended June 30, 2019:

EX-10.1

Exhibit 10.1

BORGWARNER INC.

2018 STOCK INCENTIVE PLAN

Restricted Stock Agreement—Employees

BorgWarner, Inc., a Delaware corporation (the “Company), hereby awards to the Employee indicated below a Restricted Stock Award (the “Award”) under the BorgWarner Inc. 2018 Stock Incentive Plan (the “Plan”), as specified below, effective as of the Grant Date, according to the terms and conditions of this Restricted Stock Agreement (this “Agreement”) and the Plan. All capitalized terms shall have the meanings ascribed to them in the Plan, unless specifically set forth otherwise herein. The parties hereto agree as follows:

Grant Information:

Employee Name:

Grant Date:     February 17, 2019

Number of Restricted Shares Awarded: «units» Shares

Terms and Conditions:

1. Restriction Period. Except as otherwise provided in this Agreement, the Restriction Period for the Restricted Stock awarded to the Employee under this Agreement shall commence with the Grant Date set forth above and shall end, for the percentage of the Shares indicated below (each percentage of Shares and the associated vesting date is referred to as a “Tranche”), on the date when the Restricted Stock shall have vested in accordance with the following schedule provided that the Employee remains continuously employed by or in the service of the Company or an Affiliate through the applicable vesting date:

Vesting DateVested Percentage

February 28, 2021            50% of the Awarded Shares

February 28, 2022            100% of the Awarded Shares

Notwithstanding the foregoing, if the application of the above vesting schedule would cause a fractional Share to vest, then the number of Shares that vest on such date shall be rounded down to the nearest whole number.

Prior to the date that the Restriction Period applicable to Shares of Restricted Stock lapses, the Employee shall not be permitted to sell, assign, transfer, pledge or otherwise encumber such Shares of Restricted Stock.

2. Issuance of Share Certificates or Book Entry Record.

(a) The Company shall, as soon as administratively feasible after execution of this Agreement by the Employee, either (1) issue one or more certificates in the name of the Employee representing the Shares covered by this Award, or (2) direct the Company’s transfer agent for the Stock to make a book entry record showing ownership for the Restricted Stock in the name of the Employee, subject to the terms and conditions of the Plan and this Agreement.

(b) In the event that the Company issues one or more certificates for the Restricted Stock covered by this Award in lieu of book entry, during the applicable Restriction Period:

(i) The certificate or certificates shall bear the following legend:
“The transferability of this certificate and the shares of stock represented hereby are subject to the terms and conditions (including forfeiture) of the 2018 Stock Incentive Plan and a Restricted Stock Agreement. Copies of such Plan and Restricted Stock Agreement are on file at the headquarters offices of BorgWarner Inc.”

(ii) The certificates shall be held in custody by the Company until the restrictions set forth herein shall have lapsed; and

(iii) As a condition to receipt of this Award, the Employee hereby authorizes the Company to issue such instructions to the transfer agent as the Company may deem necessary or proper to comply with the intent and purposes of this Agreement and the Plan, including provisions regarding forfeiture. This paragraph shall be deemed to constitute the stock power, endorsed in blank, contemplated by Section 8.2 of the Plan.

(c) At the Employee’s request, if and when the applicable Restriction Period expires for a Share or Shares granted hereunder without a prior forfeiture, the Company will deliver certificate(s) for such Share(s) to the Employee.

3. Termination of Employment. Except as otherwise provided in this Section 3 or Section 4, the Employee shall forfeit the Shares that are unvested as of the effective date of the Employee’s Termination of Employment. Notwithstanding the foregoing, except as otherwise determined by the Committee, in its sole discretion, at the time of the Employee’s Termination of Employment, the following provisions shall apply.

(a) Death or Disability. If the Employee’s Termination of Employment is due to the Employee’s death or Disability, then all the unvested Shares shall immediately vest.

(b) Retirement. If the Employee’s Termination of Employment is due to Retirement, then the Committee may, in its sole discretion, cause all or a portion of the unvested Shares to vest.

(c) Effective Date of Termination of Employment. For purposes of this Agreement, any Termination of Employment shall be effective as of the earlier of (1) the date that the Company receives the Employee’s notice of resignation of employment, or (2) the date that the Employee ceases to actively provide services. In connection with the foregoing, the applicable termination date shall not be extended by any notice period mandated under local law (e.g., “garden leave” or similar period pursuant to local law), and the Company shall have the exclusive discretion to determine when the Employee is no longer actively providing service for purposes of this Award. Notwithstanding the foregoing, the Employee will be deemed to have experienced a Termination of Employment upon the Employee’s “separation from service” within the meaning of Section 409A of the Code to the extent this Award is subject to Section 409A of the Code.

4. Change in Control. In the event of a Change in Control, this Award shall be treated in accordance with Section 15 of the Plan, provided, however, that for purposes of Section 15.1(a)(5), the Employee will be considered to have terminated the Employee’s employment or service for “good reason” if the Employee’s termination either (a) meets the requirements set forth in Exhibit A attached to this Agreement or (b) constitutes a “good reason” termination under the Employee’s employment, retention, change in control, severance or similar agreement with the successor, purchaser, the Company, or any affiliate thereof, if any.

5. Stockholder Rights. Subject to the restrictions imposed by this Agreement and the Plan, the Employee shall have, with respect to the Restricted Stock covered by this Award, all of the rights of a stockholder of the Company holding Stock, including the right to vote the Shares and the right to receive dividends; provided, however, that any cash dividends payable with respect to the Restricted Stock covered by this Award shall be automatically reinvested in additional Shares of Restricted Stock, the number of which shall be determined by multiplying (a) the number of Shares that the Employee has been issued under this Agreement as of the dividend record date that have not vested as of such record date by (b) the dividend paid on each Share, and dividing the result by (c) the Fair Market Value of a Share on the dividend payment date. Such additional Shares so awarded shall vest at the same time, and to the same extent, as the Restricted Stock to which it relates and shall be subject to the same restrictions, terms and conditions contained herein. Dividends payable with respect to the Restricted Stock covered by this Award that are payable in Stock shall also be paid in the form of additional Shares of Restricted Stock and shall vest at the same time, and to the same extent, as the Restricted Stock to which it relates and shall be subject to the same restrictions, terms, and conditions contained herein.

6. Tax Withholding. The Company shall have the power and the right to deduct or withhold, or require the Employee or beneficiary to remit to the Company, an amount sufficient to satisfy federal, state, and local taxes, domestic or foreign, required by law or regulation to be withheld with respect to any taxable event arising as a result of this Agreement. The Employee acknowledges that the ultimate liability for all taxes legally due by the Employee is and remains the Employee’s responsibility, and the Company: (a) makes no representations or undertakings regarding the tax treatment of this Award; and (b) does not commit to structure the terms of this Award to reduce or eliminate the Employee’s tax liability.

7. Acquisition of Shares For Investment Purposes Only. By accepting this Award, the Employee hereby agrees with the Company as follows:

(a) The Employee is acquiring the Shares covered by this Award for investment purposes only and not with a view to resale or other distribution thereof to the public in violation of the Securities Act of 1933, as amended (the “1933 Act”), and shall not dispose of any of the Shares in transactions which, in the opinion of counsel to the Company, violate the 1933 Act, or the rules and regulations thereunder, or any applicable state securities or “blue sky” laws;

(b) If any of the Shares covered by this Award shall be registered under the 1933 Act, no public offering (otherwise than on a national securities exchange, as defined in the Exchange Act) of any such Shares shall be made by the Employee (or any other person) under such circumstances that he or she (or any other such person) may be deemed an underwriter, as defined in the 1933 Act; and

(c) The Company shall have the authority to endorse upon the certificate or certificates representing the Shares covered by this Agreement such legends referring to the foregoing.

8. Miscellaneous.

(a) Nontransferability. This Award may not be sold, transferred, pledged, assigned, or otherwise alienated or hypothecated, other than by will or by the laws of descent and distribution or as otherwise permitted by the Company, and shall not be subject to execution, attachment or similar process.

(b) Notices. Any written notice required or permitted under this Agreement shall be deemed given when delivered personally, as appropriate, either to the Employee or to the Executive Compensation Department of the Company, or when deposited in a United States Post Office as registered mail, postage prepaid, addressed, as appropriate, either to the Employee at his or her address set forth above under the heading “Grant Information,” or to Attention: Executive Compensation, BorgWarner Inc., at its headquarters office or such other address as the Company may designate in writing to the Employee.

(c) Failure To Enforce Not a Waiver. The failure of the Company to enforce at any time any provision of this Agreement shall in no way be construed to be a waiver of such provision or of any other provision hereof.

(d) Governing Law. The Award made and actions taken under the Plan and this Agreement shall be governed by and construed in accordance with the laws of the State of Delaware without taking into account its conflict of laws provisions.

(e) Provisions of Plan. This Award is granted pursuant to the Plan, and this Award and this Agreement are in all respects governed by the Plan and subject to all of the terms and provisions thereof, whether such terms and provisions are incorporated in this Agreement solely by reference or expressly cited herein. It is expressly understood that the Committee is authorized to administer, construe, and make all determinations necessary or appropriate to the administration of the Plan and this Agreement, all of which shall be binding upon the Employee. If there is any conflict between the terms of this Agreement and the terms of the Plan, other than with respect to any provisions relating to Termination of Employment or Change in Control, the Plan’s terms shall supersede and replace the conflicting terms of this Agreement to the minimum extent necessary to resolve the conflict. Notwithstanding any terms of the Plan to the contrary, the termination provisions of Section 3 or the change in control provision of Section 4 of this Agreement control.

(f) Section 16 Compliance. To the extent necessary to comply with, or to avoid disgorgement of profits under the short-swing matching rules of, Section 16 of the Exchange Act, the Employee shall not sell or otherwise dispose of the Shares.

(g) No Right to Continued Employment. Nothing contained in the Plan or this Agreement shall confer upon the Employee any right to continued employment nor shall it interfere in any way with the right of the Company or any subsidiary or Affiliate to terminate the employment of the Employee at any time.

(h) Discretionary Nature of Plan; No Right to Additional Awards. The Employee acknowledges and agrees that the Plan is discretionary in nature and limited in duration and may be amended, cancelled, or terminated by the Company, in its sole discretion, at any time. The grant of an Award under the Plan is a one-time benefit and does not create any contractual or other right to receive an Award or benefits in lieu of an Award. Future awards, if any, will be at the sole discretion of the Company, including, but not limited to, the form and timing of an award, the number of Shares subject to the award, and the vesting provisions.

(i) Termination Indemnities. The value of this Award is an extraordinary item of compensation outside the scope of the Employee’s employment contract, if any. As such, Awards are not part of normal or expected compensation for purposes of calculating any severance, resignation, redundancy, end of service payments, bonuses, long-service awards, pension, or retirement benefits or similar payments.

(j) Acceptance of Award. By accepting this Award, the Employee agrees to accept all the terms and conditions of the Award, as set forth in this Agreement and in the Plan. This Agreement shall not be effective as a Restricted Stock Award if a copy of this Agreement is not signed by the Employee and returned to the Company (unless the Employee accepts this award in an alternative means approved by the Company, which may include electronic acceptance).

(k) Binding Effect. Subject to the limitations stated above, this Agreement shall be binding upon and inure to the benefit of the parties’ respective heirs, legal representatives successors and assigns.

(l) Amendment of the Agreement. Except as otherwise provided in the Plan, the Company and the Employee may amend this Agreement only by a written instrument signed by both parties.

(m) Counterparts. This Agreement may be executed in one or more counterparts, all of which together shall constitute but one Agreement.

(n) Electronic Delivery. The Company may, in its sole discretion, decide to deliver any documents related to this Award by electronic means. The Employee hereby consents to receive such documents by electronic delivery and agrees to participate in the Plan through an on-line or electronic system established and maintained by the Company or a third party designated by the Company.

(o) Entire Agreement; Headings. This Agreement is the entire agreement between the parties hereto, and all prior oral and written representations are merged into this Agreement. The headings in this Agreement are inserted for convenience and identification only and are not intended to describe, interpret, define or limit the scope, extent, or intent of this Agreement or any provision hereof.

IN WITNESS WHEREOF, BORGWARNER INC. and the Employee have executed this Agreement to be effective as of the date first written above.

BORGWARNER INC.

Exhibit A

To Restricted Stock Agreement for Employees

Definition of “Good Reason”

For purposes of Section 4 of the Agreement, the Employee will be treated as having terminated the Employee’s employment for “good reason” if, after a Change in Control, the Employee terminates employment after any of the following events occurs:

a) the assignment to the Employee of any duties inconsistent in any respect with the Employee’s position (including status, offices, titles and reporting requirements), authority, duties or responsibilities as of the date of the Change in Control or any higher position, authority, duties or responsibilities assigned to the Employee after the date of the Change in Control, or any other diminution in the Employee’s position, authority, duties or responsibilities (whether or not occurring solely as a result of the Company’s ceasing to be a publicly traded entity), excluding for this purpose an isolated, insubstantial and inadvertent action not taken in bad faith and which is remedied by the Company promptly after receipt of notice thereof given by the Employee; or

b) any failure by the Company to:

1. pay the Employee an annual base salary at least equal to twelve times the highest monthly base salary paid or payable, including any base salary which has been earned but deferred, to the Employee by the Company and its affiliated companies in respect of the twelve‑month period immediately preceding the month in which the Change in Control occurs; or

in either case, other than an isolated, insubstantial and inadvertent failure not occurring in bad faith and which is remedied by the Company promptly after receipt of notice thereof given by the Employee; or

c) the Company’s requiring the Employee, without the Employee’s consent, to:

1. be based at any office or location that is more than 35 miles from the location where the Employee was employed immediately preceding the date of the Change in Control; or

2. travel on Company business to a substantially greater extent than required immediately prior to the date of the Change in Control.

For purposes of this Exhibit, any good faith determination of “good reason” made by the Employee shall be conclusive.

BORGWARNER INC.

2018 STOCK INCENTIVE PLAN

Stock Units Award Agreement – Non-U.S. Employees

BorgWarner, Inc., a Delaware corporation (the “Company), hereby awards to the Employee indicated below a Restricted Stock Award (the “Award”) under the BorgWarner Inc. 2018 Stock Incentive Plan (the “Plan”), as specified below, effective as of the Grant Date, according to the terms and conditions of this Restricted Stock Agreement (this “Agreement”) and the Plan. All capitalized terms shall have the meanings ascribed to them in the Plan, unless specifically set forth otherwise herein. The parties hereto agree as follows:

Grant Information:

Employee Name:

Grant Date:     February 17, 2019

Number of Stock Units Awarded: [####] Stock Units. Each Stock Unit represents a contingent right to receive one Share (or a cash payment equivalent to the value of one Share) upon satisfaction of the conditions in this Agreement and the Plan.

Terms and Conditions:

1. Vesting of Stock Units. Subject to the terms and conditions of this Agreement and to the provisions of the Plan, the Stock Units shall vest in accordance with the following schedule, provided that the Employee remains continuously employed or in the service of the Company or an Affiliate through the applicable vesting date:

Vesting DateVested Percentage

February 28, 2021            50% of the Awarded Stock Units

February 28, 2022            100% of the Awarded Stock Units

Notwithstanding the foregoing, if the application of the above vesting schedule would result in the vesting of a fractional Stock Unit, then the number of Stock Units that vest on such date shall be rounded down to the nearest whole number.

2. Tracking and Settlement of Award.

(a) Bookkeeping Account. On the Grant Date, the Company shall credit the Employee’s Stock Units to a Stock Units account established and maintained for the Employee on the books of the Company. The account shall constitute the record of the Stock Units awarded to the Employee under this Agreement, is solely for accounting purposes, and shall not require a segregation of any Company assets.

(b) Issuance of Shares or Cash Payment. The Company shall deliver Shares to the Employee in settlement of the Stock Units awarded by this Agreement equal to the number of the Employee's vested Stock Units (including any additional Stock Units acquired as a result of dividend equivalents that have vested). Payment shall be made to the Employee as soon as practicable on or after the specified vesting date, but in no event no later than December 31 of the year in which the vesting date occurs. Notwithstanding the foregoing, the Company may, in its sole discretion, settle the Stock Units in the form of: (i) a cash payment to the extent settlement in shares of Stock (A) is prohibited under local law, (B) would require the Employee or the Company to obtain the approval of any governmental and/or regulatory body in the Employee’s country of residence (and/or country of employment, if different) or (C) is administratively burdensome; or (ii) Shares, but require the Employee to immediately sell such Shares (in which case, this Agreement shall give the Company the authority to issues sales instructions on behalf of the Employee).

3. Termination of Employment. Except as otherwise provided in this Section 3 or Section 4, the Employee shall forfeit the Stock Units that are unvested as of the effective date of the Employee’s Termination of Employment. Notwithstanding the foregoing, except as otherwise determined by the Committee, in its sole discretion, at the time of the Employee’s Termination of Employment, the following provisions shall apply.

(a) Death or Disability. If the Employee’s Termination of Employment is due to the Employee’s death or Disability, then all the unvested Stock Units shall immediately vest.

(b) Retirement. If the Employee’s Termination of Employment is due to Retirement, then then Committee may, in its sole discretion, cause all or a portion of the unvested Stock Units to vest.

(c) Effective Date of Termination of Employment. For purposes of this Agreement, any Termination of Employment shall be effective as of the earlier of (1) the date that the Company receives the Employee’s notice of resignation of employment, or (2) the date that the Employee ceases to actively provide services. In connection with the foregoing, the applicable termination date shall not be extended by any notice period mandated under local law (e.g., “garden leave” or similar period pursuant to local law), and the Company shall have the exclusive discretion to determine when the Employee is no longer actively providing service for purposes of the Stock Units. Notwithstanding the foregoing, the Employee will be deemed to have experienced a Termination of Employment upon the Employee’s “separation from service” within the meaning of Section 409A of the Code to the extent this Award is subject to Section 409A of the Code.

4. Change in Control. In the event of a Change in Control, this Award shall be treated in accordance with Section 15 of the Plan, provided, however, that for purposes of Section 15.1(a)(5), an Employee will be considered to have terminated the Employee’s employment or service for “good reason” if the Employee’s termination either (a) meets the requirements set forth in Exhibit A attached to this Agreement or (b) constitutes a “good reason” termination under the Employee’s employment, retention, change in control, severance or similar agreement with the successor, purchaser, the Company, or any affiliate thereof, if any.

5. Stockholder Rights; Dividend Equivalents.

(a) No Stockholder Rights. Prior to the actual delivery of Shares to the Employee in settlement of the Stock Units awarded and vested hereunder (if any), the Employee shall have no rights as a stockholder with respect to the Stock Units or any underlying Shares, including but not limited to voting or dividend rights.

(b) Dividend Equivalents. If the Company pays any cash or other dividend or makes any other distribution in respect of the Stock before the Stock Units are settled in accordance with Section 2(b) of this Agreement, the Employee’s Stock Units account shall be credited with an additional number of Stock Units (including fractions thereof) determined by multiplying (i) the number of Stock Units credited to the Employee on the dividend record date by (ii) the dividend paid on each Share, and dividing the result of such multiplication by (iii) the Fair Market Value of a Share on the dividend payment date. Credits shall be made effective as of the date of the dividend or other distribution in respect of the Stock. Dividend equivalents credited to the Employee’s account shall be subject to the same restrictions as the Stock Units in respect of which the dividends or other distribution were credited, including, without limitation, the Award’s vesting conditions and distribution provisions.

6. Tax and Social Insurance Contributions Withholding.Regardless of any action the Company and/or the affiliate that employs the Employee (the “Employer”) take with respect to any or all income tax (including U.S. federal, state and local taxes and/or non-U.S. taxes), social insurance, payroll tax, payment on account or other tax-related withholding (“Tax-Related Items”), the Employee acknowledges that the ultimate liability for all Tax-Related Items legally due by the Employee is and remains the Employee’s responsibility, and the Company and the Employer: (i) make no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of the Stock Units, including the grant of the Stock Units, the vesting of the Stock Units, the subsequent sale of any Stock acquired pursuant to the Stock Units and the receipt of any dividends or dividend equivalents; and (ii) do not commit to structure the terms of the grant or any aspect of the Stock Units to reduce or eliminate the Employee’s liability for Tax-Related Items.

Prior to the delivery of Shares upon the vesting of the Stock Units, if any taxing jurisdiction requires withholding of Tax-Related Items, the Company may withhold a sufficient number of whole Shares otherwise issuable upon the vesting of the Stock Units that have an aggregate Fair Market Value not to exceed the maximum statutory Tax-Related Items required to be withheld with respect to the Shares. The cash equivalent of the Shares withheld will be used to settle the obligation to withhold the Tax-Related Items (determined by reference to the Fair Market Value of the Stock on the applicable vesting date). No fractional Shares will be withheld or issued pursuant to the grant of the Stock Units and the issuance of Stock hereunder. Alternatively, the Company and/or the Employer may, in its discretion, withhold any amount necessary to pay the Tax-Related Items from the Employee’s salary/wages or other amounts payable to the Employee, with no withholding in Shares.

In the event the withholding requirements are not satisfied through the withholding of Shares or through the withholding from the Employee’s salary/wages or other amounts payable to the Employee, no Shares will be issued upon vesting of the Stock Units unless and until satisfactory arrangements (as determined by the Committee) have been made by the Employee with respect to the payment of any Tax-Related Items which the Company and/or the Employer determine, in its sole discretion, must be withheld or collected with respect to such Stock Units. If the Employee is subject to taxation in more than one jurisdiction, the Employee acknowledges that the Company, the Employer or another subsidiary or Affiliate may be required to withhold or account for Tax-Related Items in more than one jurisdiction. By accepting this grant of Stock Units, the Employee expressly consents to the withholding of Shares and/or the withholding of amounts from the Employee's salary/wages or other amounts payable to the Employee as provided for hereunder. All other Tax-Related Items related to the Stock Units and any Stock delivered in payment thereof are the Employee’s sole responsibility.

7. Acquisition of Shares For Investment Purposes Only. By accepting this Award, the Employee hereby agrees with the Company as follows:

(a) The Employee is acquiring the Shares covered by this Award for investment purposes only and not with a view to resale or other distribution thereof to the public in violation of the Securities Act of 1933, as amended (the “1933 Act”), and shall not dispose of any of the Shares in transactions which, in the opinion of counsel to the Company, violate the 1933 Act, or the rules and regulations thereunder, or any applicable state securities or “blue sky” laws;

(b) If any of the Shares covered by this Award shall be registered under the 1933 Act, no public offering (otherwise than on a national securities exchange, as defined in the Exchange Act) of any such Shares shall be made by the Employee (or any other person) under such circumstances that he or she (or any other such person) may be deemed an underwriter, as defined in the 1933 Act; and

(c) The Company shall have the authority to endorse upon the certificate or certificates representing the Shares covered by this Agreement such legends referring to the foregoing.

8. Miscellaneous.

(a) Nontransferability. This Award may not be sold, transferred, pledged, assigned, or otherwise alienated or hypothecated, other than by will or by the laws of descent and distribution or as otherwise permitted by the Company, and shall not be subject to execution, attachment or similar process.

(c) Failure To Enforce Not a Waiver. The failure of the Company to enforce at any time any provision of this Agreement shall in no way be construed to be a waiver of such provision or of any other provision hereof.

(d) Governing Law. The Award made and actions taken under the Plan and this Agreement shall be governed by and construed in accordance with the laws of the State of Delaware without taking into account its conflict of laws provisions.

(e) Provisions of Plan. This Award is granted pursuant to the Plan, and this Award and this Agreement are in all respects governed by the Plan and subject to all of the terms and provisions thereof, whether such terms and provisions are incorporated in this Agreement solely by reference or expressly cited herein. It is expressly understood that the Committee is authorized to administer, construe, and make all determinations necessary or appropriate to the administration of the Plan and this Agreement, all of which shall be binding upon the Employee. If there is any conflict between the terms of this Agreement and the terms of the Plan, other than with respect to any provisions relating to Termination of Employment or Change in Control, the Plan’s terms shall supersede and replace the conflicting terms of this Agreement to the minimum extent necessary to resolve the conflict. Notwithstanding any terms of the Plan to the contrary, the termination provisions of Section 3 and the change in control provisions of Section 4 of this Award control.

(f) Section 16 Compliance. To the extent necessary to comply with, or to avoid disgorgement of profits under the short-swing matching rules of, Section 16 of the Exchange Act, the Employee shall not sell or otherwise dispose of the Shares issued as payment for any earned Stock Units.

(g) 409A Six Month Delay. If the Employee is a “specified employee” within the meaning of Section 409A of the Code at the time of the Employee’s Termination of Employment, then any payment made to the Employee as a result of such Termination of Employment shall be delayed for six months following the Employee’s termination to the extent required by Section 409A of the Code.

(h) No Right to Continued Employment. Nothing contained in the Plan or this Agreement shall confer upon the Employee any right to continued employment nor shall it interfere in any way with the right of the Employer to terminate the employment of the Employee at any time.

(i) Discretionary Nature of Plan; No Right to Additional Awards. The Employee acknowledges and agrees that the Plan is discretionary in nature and limited in duration, and may be amended, cancelled, or terminated by the Company, in its sole discretion, at any time. The grant of an Award under the Plan is a one-time benefit and does not create any contractual or other right to receive an Award or benefits in lieu of an Award. Future Awards, if any, will be at the sole discretion of the Company, including, but not limited to, the form and timing of an award, the number of Shares subject to the award, and the vesting provisions.

(j) Termination Indemnities. The value of this Award is an extraordinary item of compensation outside the scope of the Employee’s employment contract, if any. As such, Awards are not part of normal or expected compensation for purposes of calculating any severance, resignation, redundancy, end of service payments, bonuses, long-service awards, pension, or retirement benefits or similar payments.

(n) Entire Agreement; Headings. This Agreement is the entire agreement between the parties hereto, and all prior oral and written representations are merged into this Agreement. The headings in this Agreement are inserted for convenience and identification only and are not intended to describe, interpret, define or limit the scope, extent, or intent of this Agreement or any provision hereof.

The Employee hereby consents to receive such documents by electronic delivery and agrees to participate in the Plan through an on-line or electronic system established and maintained by the Company or a third party designated by the Company.

(p) Private Placement. The grant of the Stock Units is not intended to be a public offering of securities in the Employee’s country of residence (or country of employment, if different) but instead is intended to be a private placement. As a private placement, the Company has not submitted any registration statement, prospectus or other filings with the local securities authorities (unless otherwise required under local law), and the grant of the Stock Units is not subject to the supervision of the local securities authorities.

(q) Consent to Collection, Processing and Transfer of Personal Data. Pursuant to applicable personal data protection laws, the Company and the Employer hereby notify the Employee of the following in relation to the Employee’s personal data and the collection, use, processing and transfer of such data in relation to the Company’s grant of this Award and the Employee’s participation in the Plan. The collection, use, processing and transfer of the Employee’s personal data is necessary for the Company’s administration of the Plan and the Employee’s participation in the Plan. The Employee’s denial and/or objection to the collection, use, processing and transfer of personal data may affect the Employee’s participation in the Plan. As such, the Employee voluntarily acknowledges and consents (where required under applicable law) to the collection, use, processing and transfer of personal data as described herein.

The Data maybe provided by the Employee or collected, where lawful, from third parties, and the Company and the Employer each will process the Data for the exclusive purpose of implementing, administering and managing the Employee’s participation in the Plan. The Data processing will take place through electronic and non-electronic means according to logics and procedures strictly correlated to the purposes for which the Data is collected and with confidentiality and security provisions as set forth by applicable laws and regulations in the Employee’s country of residence (and country of employment, if different). Data processing operations will be performed minimizing the use of personal and identification data when such operations are unnecessary for the processing purposes sought. Data will be accessible within the Company’s organization only by those persons requiring access for purposes of the implementation, administration and operation of the Plan and for the Employee’s participation in the Plan.

The Company and the Employer each will transfer Data internally as necessary for the purpose of implementation, administration and management of the Employee’s participation in the Plan, and the Company and the Employer each may further transfer Data to any third parties assisting the Company in the implementation, administration and management of the Plan. These recipients may be located in the European Economic Area, or elsewhere throughout the world, such as the United States. The Employee hereby authorizes (where required under applicable law) them to receive, possess, use, retain and transfer the Data, in electronic or other form, for purposes of implementing, administering and managing the Employee’s participation in the Plan, including any requisite transfer of such Data as may be required for the administration of the Plan and/or the subsequent holding of shares of Stock on the Employee’s behalf by a broker or other third party with whom the Employee may elect to deposit any shares of Stock acquired pursuant to the Plan.

The Employee may, at any time, exercise his or her rights provided under applicable personal data protection laws, which may include the right to (a) obtain confirmation as to the existence of the Data, (b) verify the content, origin and accuracy of the Data, (c) request the integration, update, amendment, deletion, or blockage (for breach of applicable laws) of the Data, and (d) to oppose, for legal reasons, the collection, processing or transfer of the Data which is not necessary or required for the implementation, administration and/or operation of the Plan and the Employee’s participation in the Plan. The Employee may seek to exercise these rights by contacting the Employer's local HR manager or the Company’s Human Resources Department.

To the extent a court or tribunal of competent jurisdiction determines that any provision of the Award is invalid or unenforceable, in whole or in part, under the Age Discrimination Rules, the Company, in its sole discretion, shall have the power and authority to revise or strike such provision to the minimum extent necessary to make it valid and enforceable to the full extent permitted under local law.

(s) Repatriation; Compliance with Laws. The Employee agrees, as a condition of the grant of the Stock Units, to repatriate all payments attributable to the Stock Units and/or cash acquired under the Plan (including, but not limited to, dividends, dividend equivalents, and any proceeds derived from the sale of the Stock acquired pursuant to the Stock Units) in accordance with all foreign exchange rules and regulations applicable to the Employee. In addition, the Employee also agrees to take any and all actions, and consents to any and all actions taken by the Company and its subsidiaries and Affiliates, as may be required to allow the Company and its subsidiaries and Affiliates to comply with all applicable laws, rules and regulations. Finally, the Employee agrees to take any and all actions as may be required to comply with the Employee’s personal legal and tax obligations under all applicable laws, rules and regulations.

The Employee acknowledges and agrees that it is the Employee’s express intent that this Agreement, the Plan and all other documents, notices and legal proceedings entered into, given or instituted pursuant to the Stock Units, be drawn up in English. If the Employee has received this Agreement, the Plan or any other documents related to the Stock Units translated into a language other than English, and if the meaning of the translated version is different than the English version, the English version shall control.

(u) Additional Requirements. The Company reserves the right to impose other requirements on the Stock Units, any Shares acquired pursuant to the Stock Units, and the Employee’s participation in the Plan, to the extent the Company determines, in its sole discretion, that such other requirements are necessary or advisable in order to comply with local laws, rules and/or regulations or to facilitate the operation and administration of the Stock Units and the Plan. Such requirements may include (but are not limited to) requiring the Employee to sign any agreements or undertakings that may be necessary to accomplish the foregoing.

Further, if the Employee transfers the Employee’s residence and/or employment to another country reflected in an Addendum, the special terms and conditions for such country will apply to the Employee to the extent the Company determines, in its sole discretion, that the application of such terms and conditions is necessary or advisable in order to comply with local laws, rules and/or regulations or to facilitate the operation and administration of the Stock Units and the Plan (or the Company may establish alternative terms and conditions as may be necessary or advisable to accommodate the Employee’s transfer). In all circumstances, any applicable Addendum shall constitute part of this Agreement.

Exhibit 10.3

BORGWARNER INC.2018 STOCK INCENTIVE PLAN

Performance Share Award Agreement

BorgWarner Inc., a Delaware corporation (the “Company”) hereby awards to the Employee indicated below a Performance Share Award (the “Award”) under the BorgWarner Inc. 2018 Stock Incentive Plan (the “Plan”), as specified below, effective as of the Grant Date, according to the terms and conditions of this Performance Share Award Agreement (this “Agreement”) and the Plan. All capitalized terms shall have the meanings ascribed to them in the Plan, unless specifically set forth otherwise herein. The parties hereto agree as follows:

Grant Information:

Employee Name:

Employee Address:

Grant Date:February 17, 2019

Target Number of Performance Shares:     (a)    

(b)    

Performance Period: January 1, 2019 to December 31, 2021

Performance Measures:

(a) Company’s Total Shareholder Return Percentile Rank Among Total Shareholder Return of the Peer Group Companies

(b) Relative Revenue Growth

Terms and Conditions

1. Performance Goals.

(a) The number of Performance Shares specified in (a) to be earned under this Agreement shall be based upon the Company’s Total Shareholder Return as compared to the Total Shareholder Return of companies in the Peer Group (identified in Exhibit A) for the Performance Period. For this purpose, “Total Shareholder Return” shall be determined as follows:

Total Shareholder        =    Change in Stock Price + Dividends Paid

    Return (“TSR”)                Beginning Stock Price

“Beginning Stock Price” shall mean the closing price as reported on the New York Stock Exchange Composite Tape of one (1) share of stock on the last trading day immediately prior to the first day of the Performance Period. “Ending Stock Price” shall mean the closing price as reported on the New York Stock Exchange Composite Tape of one (1) share of stock for the last trading day immediately prior to the end of the Performance Period. “Change in Stock Price” shall mean the difference between the Beginning Stock Price and the Ending Stock Price. Finally, “Dividends Paid” shall mean the total of all dividends paid on one (1) share of stock during the Performance Period, provided that dividends shall be treated as though they are reinvested on their respective payment dates.

Following the TSR determination, the Company’s Percentile Rank shall be determined as follows:

Percentile Rank		Company Rank minus one
	=	Total Number of Companies in the Peer Group.

Company Rank shall be determined by listing, from highest TSR to lowest TSR, each company in the Peer Group plus the Company and counting up from the company with the lowest TSR.

The percent of the Target Number of Performance Shares specified in (a) earned under the Total Shareholder Return Performance Measure shall then be determined based on the following chart:

Company’s Percentile Rank	Percent of Target Number of Performance Shares Earned
75th and above 65th 50th 35th 25th Below 25th	200.0% 160.0% 100.0%  55.0%  25.0%   0.0%

Interpolation shall be used to determine the percent of Target Number of Performance Shares earned in the event the Company’s Percentile Rank does not fall directly on one of the ranks listed in the above chart.

(b) The number of Performance Shares specified in (b) to be earned under this Agreement shall be based upon the Company’s Relative Revenue Growth. For this purpose, Relative Revenue Growth is defined as the percentage by which the Company’s compound annual percentage change in revenue, excluding the impact of changes in foreign currency exchange rates and merger, acquisition and divestiture activity, for the Performance Period exceeds the compound annual percentage change in the vehicle market for the Performance Period.

The percentage change in the vehicle market will be determined by weighting the change in vehicle production over the Performance Period among the passenger car, on-highway commercial vehicle and off-highway commercial vehicle markets across the geographic markets of North America, South America, Europe, China, India, Japan and South Korea in proportion to the Company’s revenue distribution at the end of the Performance Period across those same geographic vehicle market segments.

The percent of the Target Number of Performance Shares specified in (b) earned under the Relative Revenue Growth Performance Measure shall then be determined based on the following chart:

Company’s Percentage Change in Revenue above Weighted Percentage Change in Vehicle Market	Percent of Target Number of Performance Shares Earned
6% and above	200.00%
4%	100.00%
2%	50.00%
Less than 2%	0.00%

Interpolation shall be used to determine the percent of Target Number of Performance Shares earned in the event the Company’s percentage change in revenue above the weighted percentage change in the vehicle market does not fall directly on one of the percentages listed in the above chart.

2. Form and Timing of Payment of Performance Shares. The Company shall deliver to the Employee one Share in settlement of each earned Performance Share. At the end of the Performance Period, the Committee shall determine, in its sole discretion, the number of Performance Shares that have been earned based on the achievement of the Performance Goals described in Section 1 of this Agreement. Except as otherwise provided in Section 4, payment shall be made as soon as administratively practicable in the year after the year in which the Performance Period ends, but in any event, no later than March 15 of the year following the year in which the Performance Period ends.

3. Termination of Employment. Except as otherwise provided in this Section 3 or Section 4, the Employee shall be eligible for payment of earned Performance Shares, as specified in Section 2, only if the Employee’s employment with the Company continues through the end of the Performance Period and the Employee does not give notice of the Employee’s voluntary Termination of Employment on or before the end of the Performance Period. Notwithstanding the foregoing, unless otherwise determined by the Committee, in its sole discretion, at the time of the Employee’s Termination of Employment, the following provisions shall apply.

(a) Termination for Cause. If the Employee experiences a Termination of Employment for Cause at any time prior to the payment of Shares in settlement of this Award, then the Employee shall forfeit any rights under this Award, including, for the avoidance of doubt, rights with respect to any earned Performance Shares.

(b) Death, Disability, Retirement or Involuntary Termination without Cause. If the Employee experiences a Termination of Employment prior to the end of the Performance Period due to the Employee’s death, Disability, Retirement or involuntary termination without Cause, the Committee at its sole discretion, may waive the requirement that the participant must be employed by the Company through the end of the Performance Period. In such case, the Employee shall be eligible for all or that proportion of the Performance Shares earned (determined at the end of the Performance Period and based on actual results). Such proportion shall be calculated as follows, rounded down to the nearest whole number: (i) the total number of Performance Shares that the Employee would have earned absent the Employee’s Termination of Employment, calculated according to Section 1 of this Agreement multiplied by (ii) a fraction, the numerator of which equals the total number of full months that the Employee was employed during the Performance Period, and the denominator of which equals the total number of full months during the Performance Period.

(c) Effective Date of Termination of Employment. For purposes of this Agreement, any Termination of Employment shall be effective as of the earlier of (1) the date that the Company receives the Employee’s notice of resignation of employment, or (2) the date that the Employee ceases to actively provide services. In connection with the foregoing, the applicable termination date shall not be extended by any notice period mandated under local law (e.g., “garden leave” or similar period pursuant to local law), and the Company shall have the exclusive discretion to determine when the Employee is no longer actively providing services for purposes of this Award. Notwithstanding the foregoing, the Employee will be deemed to have experienced a Termination of Employment upon the Employee’s “separation from service” within the meaning of Section 409A of the Code to the extent this Award is subject to Section 409A of the Code.

4. Change in Control. In the event of a Change in Control, this Award shall be treated in accordance with Section 15 of the Plan, provided, however, that for purposes of Section 15.1(a)(5), an Employee will be considered to have terminated the Employee’s employment or service for “good reason” if the Employee’s termination either (a) meets the requirements set forth in Exhibit B attached to this Agreement or (b) constitutes a “good reason” termination under the Employee’s employment, retention, change in control, severance or similar agreement with the successor, purchaser, the Company, or any affiliate thereof, if any.

5. Stockholder Rights. The Employee shall have no rights as a stockholder, (including rights to dividends) with respect to the Stock underlying the Performance Shares unless and until Shares are delivered to the Employee under this Agreement.

6. Tax Withholding. The Company shall have the power and the right to deduct or withhold, or require the Employee or beneficiary to remit to the Company, an amount sufficient to satisfy federal, state, and local taxes, domestic or foreign, required by law or regulation to be withheld with respect to any taxable event arising as a result of this Agreement. The Employee acknowledges that the ultimate liability for all taxes legally due by the Employee is and remains the Employee’s responsibility, and the Company: (a) makes no representations or undertakings regarding the tax treatment of this Award; and (b) does not commit to structure the terms of this Award to reduce or eliminate the Employee’s tax liability.

7. Acquisition of Shares for Investment Purposes Only. By accepting this Award, the Employee hereby agrees with the Company as follows:

(a) The Employee shall acquire the Shares issuable with respect to the Performance Shares granted hereunder for investment purposes only and not with a view to resale or other distribution thereof to the public in violation of the Securities Act of 1933, as amended (the “1933 Act”), and shall not dispose of any such Shares in transactions which, in the opinion of counsel to the Company, violate the 1933 Act, or the rules and regulations thereunder, or any applicable state securities or “blue sky” laws.

(b) If any Shares acquired with respect to the Performance Shares shall be registered under the 1933 Act, no public offering (otherwise than on a national securities exchange, as defined in the Exchange Act) of any such Shares shall be made by the Employee under such circumstances that he or she (or such other person) may be deemed an underwriter, as defined in the 1933 Act; and

(c) The Company shall have the authority to endorse upon the certificate or certificates representing the Shares acquired hereunder such legends referring to the foregoing.

8. Miscellaneous.

(a) Nontransferability. Performance Shares may not be sold, transferred, pledged, assigned, or otherwise alienated or hypothecated, other than by will or by the laws of descent and distribution or as otherwise permitted by the Company, and shall not be subject to execution, attachment or similar process.

(b) Notices. Any written notice required or permitted under this Agreement shall be deemed given when delivered personally, as appropriate, either to the Employee or to the Executive Compensation Department of the Company, or when deposited in a United States Post Office as registered mail, postage prepaid, addressed, as appropriate, either to the Employee at his or her address set forth above under the heading “Grant Information,” or such other address as he or she may designate in writing to the Company, or to the Attention: Executive Compensation, BorgWarner Inc., at its headquarters office or such other address as the Company may designate in writing to the Employee.

(c) Failure To Enforce Not a Waiver. The failure of the Company to enforce at any time any provision of this Agreement shall in no way be construed to be a waiver of such provision or of any other provision hereof.

(d) Governing Law. This grant of Performance Shares and actions taken under the Plan and this Agreement shall be governed by and construed in accordance with the laws of the State of Delaware without taking into account its conflict of laws provisions.

(e) Provisions of Plan. The Performance Shares provided for herein are granted pursuant to the Plan, and said Performance Shares and this Agreement are in all respects governed by the Plan and subject to all of the terms and provisions thereof, whether such terms and provisions are incorporated in this Agreement solely by reference or expressly cited herein. It is expressly understood that the Committee is authorized to administer, construe, and make all determinations necessary or appropriate to the administration of the Plan and this Agreement, all of which shall be binding upon the Employee. If there is any conflict between the terms of this Agreement and the terms of the Plan, other than with respect to any provisions relating to Termination of Employment or Change in Control, the Plan’s terms shall supersede and replace the conflicting terms of this Agreement to the minimum extent necessary to resolve the conflict. Notwithstanding any terms of the Plan to the contrary, the termination provisions of Section 3 and the change in control provisions of Section 4 of this Award control.

(f) Section 16 Compliance. To the extent necessary to comply with, or to avoid disgorgement of profits under the short-swing matching rules of, Section 16 of the Exchange Act, the Employee shall not sell or otherwise dispose of the Shares issued as payment for any earned Performance Shares.

(g) 409A Six Month Delay. If the Employee is a “specified employee” within the meaning of Section 409A of the Code at the time of the Employee’s Termination of Employment, then any payment made to the Employee as a result of such Termination of Employment shall be delayed for six months following the Employee’s termination to the extent required by Section 409A of the Code.

(h) No Right to Continued Employment. Nothing contained in the Plan or this Agreement shall confer upon the Employee any right to continued employment nor shall it interfere in any way with the right of the Employer to terminate the employment of the Employee at any time.

(i) Discretionary Nature of Plan; No Right to Additional Awards. The Employee acknowledges and agrees that the Plan is discretionary in nature and limited in duration, and may be amended, cancelled, or terminated by the Company, in its sole discretion, at any time. The grant of an Award under the Plan is a one-time benefit and does not create any contractual or other right to receive an Award or benefits in lieu of an Award. Future Awards, if any, will be at the sole discretion of the Company, including, but not limited to, the form and timing of an award, the number of Shares subject to the award, and the vesting provisions.

(j) Termination Indemnities. The value of this Award is an extraordinary item of compensation outside the scope of the Employee’s employment contract, if any. As such, Awards are not part of normal or expected compensation for purposes of calculating any severance, resignation, redundancy, end of service payments, bonuses, long-service awards, pension, or retirement benefits or similar payments.

(k) Acceptance of Award. By accepting this Award, the Employee agrees to accept all the terms and conditions of the Award, as set forth in this Agreement and in the Plan. This Agreement shall not be effective as a Performance Share Award if a copy of this Agreement is not signed by the Employee and returned to the Company (unless the Employee accepts this award in an alternative means approved by the Company, which may include electronic acceptance).

(l) Binding Effect. Subject to the limitations stated above, this Agreement shall be binding upon and inure to the benefit of the parties’ respective heirs, legal representatives successors and assigns.

(m) Amendment of the Agreement. Except as otherwise provided in the Plan, the Company and the Employee may amend this Agreement only by a written instrument signed by both parties.

(n) Counterparts. This Agreement may be executed in one or more counterparts, all of which together shall constitute but one Agreement.

(o) Electronic Delivery. The Company may, in its sole discretion, decide to deliver any documents related to the Performance Shares by electronic means. The Employee hereby consents to receive such documents by electronic delivery and agrees to participate in the Plan through an on-line or electronic system established and maintained by the Company or a third party designated by the Company.

(p) Entire Agreement; Headings. This Agreement is the entire agreement between the parties hereto, and all prior oral and written representations are merged into this Agreement. The headings in this Agreement are inserted for convenience and identification only and are not intended to describe, interpret, define or limit the scope, extent, or intent of this Agreement or any provision hereof.

3. Custody of Share Certificates During the Restriction Period. In the event that the Company issues one or more certificates for the Restricted Stock covered by this Award in lieu of book entry, during the Restriction Period described below:

a. The certificate or certificates shall bear the following legend:

c. As a condition to receipt of this Award, the Director hereby authorizes the Company to issue such instructions to the transfer agent as the Company may deem necessary or proper to comply with the intent and purposes of this Agreement and the Plan, including provisions regarding forfeiture, and that this paragraph shall be deemed to constitute the stock power, endorsed in blank, contemplated by Section 8.2 of the Plan.

Exhibit 10.4

c. The Company shall have the authority to endorse upon the certificate or certificates representing the Stock covered by this Agreement such legends referring to the foregoing restrictions.

2018 STOCK INCENTIVE PLAN

Stock Units Award Agreement – Non-U.S. Directors

THIS Award Agreement (the “Agreement”) dated as of April 24, 2019, by and between BORGWARNER INC., a Delaware corporation (the “Company”), and

________, a non-employee member of the Company’s Board of Directors (the “Board”) resident in _______ (the “Director”), is entered into as follows:

WITNESSETH:

WHEREAS, the Company has established the BorgWarner Inc. 2018 Stock Incentive Plan (the “Plan”), a copy of which is attached hereto or which has been previously provided to the Director;

WHEREAS, the Corporate Governance Committee of the Board has determined that the Director be granted Stock Units pursuant to the terms of the Plan and the terms of this Agreement, and the Board has approved such recommendation.

NOW, THEREFORE, in consideration of the foregoing and the mutual covenants hereinafter set forth:

1. Award of Stock Units. The Company hereby awards to the Director on this date, 2,985 Stock Units. Each Stock Unit awarded hereunder represents a contingent right to receive one share of the Company’s common stock, par value $.01 (“Stock”), upon satisfaction of the conditions for vesting as provided in paragraph 4 of this Agreement and subject further to the terms of the Plan and the additional terms and conditions of this Agreement (the “Award”).

2. Stock Units. The Company shall credit the Director’s Stock Units to a Stock Units account established and maintained for the Director on the books of the Company payable in shares or cash. The account shall constitute the record of the Stock Units awarded to the Director under this Agreement, is solely for accounting purposes, and shall not require a segregation of any Company assets.

3. Dividend Equivalents. If the Company pays any cash or other dividend or makes any other distribution in respect of the Stock before the Stock Units are settled in accordance with paragraph 7 of this Agreement, then the Director’s account shall be credited with an additional number of Stock Units (including fractions thereof) determined by multiplying (i) the number of Stock Units credited to the Director on the dividend record date by (ii) the dividend paid on each share of Stock, and dividing the result of such multiplication by (iii) the Fair Market Value of a share of Stock on the dividend payment date. Credits shall be made effective as of the

Exhibit 10.5

date of the dividend or other distribution in respect of the Stock. Dividend equivalents credited to the Director’s account shall be subject to the same restrictions as the Stock Units in respect of which the dividends or other distribution were credited, including, without limitation, the Award’s vesting conditions and distribution provisions.

4. Vesting of Stock Units. Subject to the terms and conditions of this Agreement and to the provisions of the Plan, the Stock Units shall vest in accordance with the following schedule:

DateVested Percentage

5. Forfeiture of Stock Units. Upon the Director’s Termination of Employment as a member of the Board, any unvested Stock Units shall be forfeited by the Director as of the termination date; provided, however, that in the event that Director terminates service as a member of the Board by reason of Retirement, the Compensation Committee shall have the discretion to accelerate the vesting of the Stock Units, in whole or in part. For purposes of the foregoing, if the Director is a local national of a country that is a member of the European Union, the grant of the Stock Units and the terms and conditions governing the Award are intended to comply with the age discrimination provisions of the EU Equal Treatment Framework Directive, as implemented into local law (the “Age Discrimination Rules”). To the extent a court or tribunal of competent jurisdiction determines that any provision of the Award is invalid or unenforceable, in whole or in part, under the Age Discrimination Rules, the Company, in its sole discretion, shall have the power and authority to revise or strike such provision to the minimum extent necessary to make it valid and enforceable to the full extent permitted under local law.

6. Change in Control. In the event of a Change in Control, this Award shall be treated in accordance with Section 15 of the Plan.

7. Delivery of Stock. The Company shall deliver Stock to the Director in settlement of the Stock Units awarded by this Agreement equal to the number of the Director's vested Stock Units (including any additional Stock Units acquired as a result of dividend equivalents that have vested). Payment shall be made to the Director as soon as practicable on or after the specified vesting date, but in no event no later than December 31 of the year following the year in which the Stock Units vest. Notwithstanding the foregoing, the Company may, in its sole discretion, settle the Stock Units (a) in the form of a cash payment, or (b) in the form of Stock but require the Director to immediately sell such Stock (in which

Page 2 of 8

4811-4098-0578.3

Exhibit 10.5

case this Agreement shall serve as the Director’s authorization for such sale of Stock).

8. Acquisition of Stock Units For Investment Purposes Only. By his or her signature hereto, the Director hereby agrees with the Company as follows:

a. The Director is acquiring the Stock Units covered by this Award and the Shares issued under this Award for investment purposes only and not with a view to resale or other distribution thereof to the public in violation of the Securities Act of 1933, as amended (the “1933 Act”), and shall not dispose of any of the Shares issued under this Award in transactions which, in the opinion of counsel to the Company, violate the 1933 Act, or the rules and regulations thereunder, or any applicable state securities or “blue sky” laws;

b. If any of the Shares issued under this Award shall be registered under the 1933 Act, no public offering (otherwise than on a national securities exchange, as defined in the Exchange Act) of any such Shares shall be made by the Director (or any person) under such circumstances that he or she (or any other such person) may be deemed an underwriter, as defined in the 1933 Act; and

c. The Company shall have the authority to endorse upon the certification or certificates representing the Shares covered by this Award such legends referring to the foregoing restrictions.

9. Repatriation; Compliance with Laws. The Director agrees, as a condition of the grant of the Stock Units, to repatriate all payments attributable to the Stock Units and/or cash acquired under the Plan (including, but not limited to, dividends, dividend equivalents, and any proceeds derived from the sale of the Stock acquired pursuant to the Stock Units) in accordance with all foreign exchange rules and regulations applicable to the Director. In addition, the Director also agrees to take any and all actions, and consent to any and all actions taken by the Company and its subsidiaries and Affiliates, as may be required to allow the Company and its subsidiaries and Affiliates to comply with all laws, rules and regulations applicable to the Director. Finally, the Director agrees to take any and all actions as may be required to comply with the Director’s personal legal and tax obligations under all laws, rules and regulations applicable to the Director.

Exhibit 10.5

11. No Rights as a Stockholder. Prior to the actual delivery of Stock to the Director in settlement of the Stock Units awarded and vested hereunder (if any), the Director shall have no rights as a stockholder with respect to the Stock Units or any underlying Stock.

12. No Right to Continued Service. Nothing contained in the Plan or this Agreement shall confer upon the Director any right to continue as a member of the Board.

13. Discretionary Nature of Plan; No Vested Rights. The Director acknowledges and agrees that the Plan is discretionary in nature and limited in duration and may be amended, cancelled, or terminated by the Company, in its sole discretion, at any time. The grant of the Stock Units under the Plan is a one-time benefit and does not create any contractual or other right to receive an award or benefits in lieu of Stock Units in the future. Future awards, if any, will be at the sole discretion of the Company, including, but not limited to, the form and timing of an award, the number of shares of Stock subject to the award, and the vesting provisions.

14. Private Placement. The grant of the Stock Units is not intended to be a public offering of securities in the Director’s country of residence but instead is intended to be a private placement. As a private placement, the Company has not submitted any registration statement, prospectus or other filings with the local securities authorities (unless otherwise required under local law), and the grant of the Stock Units is not subject to the supervision of the local securities authorities.

15. Consent to Collection, Processing and Transfer of Personal Data. Pursuant to applicable personal data protection laws, the Company hereby notifies the Director of the following in relation to the Director’s personal data and the collection, processing and transfer of such data in relation to the Company’s grant of this Award and the Director’s participation in the Plan. The collection, processing and transfer of the Director’s personal data is necessary for the Company’s administration of the Plan and the Director’s participation in the Plan. The Director’s denial and/or objection to the collection, processing and transfer of personal data may affect the Director’s participation in the Plan. As such, the Director voluntarily acknowledges and consents (where required under applicable law) to the collection, use, processing and transfer of personal data as described herein.

The Company holds certain personal information about the Director, including name, home address and telephone number, date of birth, social security number or other tax identification number, nationality, job title, any shares of Stock or directorships held in the Company, details of all Stock Units, or any other entitlement to shares of Stock awarded, canceled, purchased, vested, unvested or outstanding in the Director’s favor, for the purpose of managing and administering the Plan (“Data”).

collected, where lawful, from third parties, and the Company will process the Data for the exclusive purpose of implementing, administering and managing the Director’s participation in the Plan. The Data processing will take place through electronic and non-electronic means according to logic and procedures strictly correlated to the purposes for which Data are collected and with confidentiality and security provisions as set forth by applicable laws and regulations in the Director’s country of residence. Data processing operations will be performed minimizing the use of personal and identification data when such operations are unnecessary for the processing purposes sought. Data will be accessible within the Company’s organization only by those persons requiring access for purposes of the implementation, administration and operation of the Plan and for the Director’s participation in the Plan.
The Company will transfer Data as necessary for the purpose of implementation, administration and management of the Director’s participation in the Plan, and the Company may further transfer Data to any third parties assisting the Company in the implementation, administration and management of the Plan. These recipients may be located in the European Economic Area, or elsewhere throughout the world, such as the United States. The Director hereby authorizes (where required under applicable law) them to receive, possess, use, retain and transfer the Data, in electronic or other form, for purposes of implementing, administering and managing the Director’s participation in the Plan, including any requisite transfer of such Data as may be required for the administration of the Plan and/or the subsequent holding of shares of Stock on the Director’s behalf to a broker or other third party with whom the Director may elect to deposit any shares of Stock acquired pursuant to the Plan.

The Director may, at any time, exercise his or her rights provided under applicable personal data protection laws, which may include the right to (a) obtain confirmation as to the existence of the Data, (b) verify the content, origin and accuracy of the Data, (c) request the integration, update, amendment, deletion, or blockage (for breach of applicable laws) of the Data, and (d) to oppose, for legal reasons, the collection, processing or transfer of the Data which is not necessary or required for the implementation, administration and/or operation of the Plan and the Director’s participation in the Plan.

Exhibit 10.5

17. Tax and Social Insurance Contributions Withholding.Regardless of any action the Company may take with respect to any or all income tax or other tax-related items pertaining to the Stock Units (“Tax-Related Items”), the Director acknowledges that the ultimate liability for all Tax-Related Items legally due by the Director is and remains the Director’s responsibility and that the Company (i) makes no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of the Stock Units, including the grant of the Stock Units, the vesting of the Stock Units, the subsequent sale of any Stock acquired pursuant to the Stock Units and the receipt of any dividends or dividend equivalents; and (ii) does not commit to structure the terms of the grant or any aspect of the Stock Units to reduce or eliminate the Director’s liability for Tax-Related Items.Prior to the delivery of the Stock upon the vesting of the Stock Units, if any taxing jurisdiction requires withholding of Tax-Related Items, the Company may withhold a sufficient number of whole shares of Stock otherwise issuable upon the vesting of the Stock Units that have an aggregate Fair Market Value not to exceed the maximum statutory Tax-Related Items required to be withheld with respect to the Shares. The cash equivalent of the Shares withheld will be used to settle the obligation to withhold the Tax-Related Items (determined by reference to the Fair Market Value of the Stock on the applicable vesting date. No fractional shares of Stock will be withheld or issued pursuant to the grant of the Stock Units and the issuance of Stock hereunder.

18. Electronic Delivery. The Company may, in its sole discretion, decide to deliver any documents related to the Stock Units granted to the Director under the Plan by electronic means. The Director hereby consents to receive such documents by electronic delivery and agrees to participate in the Plan through an on-line or electronic system established and maintained by the Company or a third party designated by the Company.

19. English Language. The Director acknowledges and agrees that it is the Director’s express intent that this Agreement, the Plan and all other documents, notices and legal proceedings entered into, given or instituted pursuant to the Stock Units be drawn up in English. If the Director has received this Agreement, the Plan or any other documents related to the Stock Units translated into a language other than English, and if the meaning of the translated version is different than the English version, the English version shall control.

20. Additional Requirements. The Company reserves the right to impose other requirements on the Stock Units, any shares of Stock acquired pursuant to the Stock Units, and the Director’s participation in the Plan, to the extent the Company determines, in its sole discretion, that such other requirements are necessary or advisable in order to comply with local law or to facilitate the administration of the Plan. Such requirements may include (but are not limited

22. Binding Effect. Subject to the limitations stated above, this Agreement shall be binding upon and inure to the benefit of the parties’ respective heirs, legal representatives successors and assigns.

23. Change in Capital or Corporate Structure. In the event of any merger, reorganization, consolidation, recapitalization, stock dividend, stock split, extraordinary distribution with respect to the Stock, other change in corporate structure affecting the Stock or any other event, which other event the Compensation Committee determines necessitates an adjustment to prevent dilution or enlargement of the benefits or potential benefits intended to be made available hereunder, this Agreement shall be adjusted pursuant to Section 4.4 of the Plan.

24. Entire Agreement. This Agreement is the entire agreement between the parties hereto, and all prior oral and written representations are merged into this Agreement. The headings in this Agreement are inserted for convenience and identification only and are not intended to describe, interpret, define or limit the scope, extent, or intent of this Agreement or any provision hereof.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation

Basis of Presentation

The accompanying unaudited Condensed Consolidated Financial Statements of BorgWarner Inc. and Consolidated Subsidiaries (the “Company”) have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes necessary for a comprehensive presentation of financial position, results of operations and cash flow activity required by GAAP for complete financial statements. In the opinion of management, all normal recurring adjustments necessary for a fair statement of results have been included. Operating results for the three and six months ended June 30, 2019 are not necessarily indicative of the results that may be expected for the year ending December 31, 2019. The balance sheet as of December 31, 2018 was derived from the audited financial statements as of that date. For further information, refer to the Consolidated Financial Statements and Footnotes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2018.

Certain prior period amounts have been reclassified to conform to current period presentation. Management makes estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and accompanying notes, as well as the amounts of revenues and expenses reported during the periods covered by those financial statements and accompanying notes. Actual results could differ from these estimates.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]

New Accounting Pronouncements

New Accounting Pronouncements

Recently Adopted Accounting Standards

In February 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2016-02, "Leases (Topic 842)." Under this guidance, a lease is a contract, or part of a contract, that conveys the right to control the use of an identified asset for a period of time in exchange for consideration. Lessees are required to recognize a right-of-use asset and a lease liability for leases with a term more than 12 months, including operating leases defined under previous GAAP. This guidance was effective for interim and annual reporting periods beginning after December 15, 2018.

The Company adopted Accounting Standards Codification ("ASC") 842 as of January 1, 2019, using the optional transition method provided in ASU No. 2018-11, "Leases (Topic 842): Targeted Improvements." Under this method, the Company recorded an adjustment as of the effective date and did not include any retrospective adjustments to comparative periods to reflect the adoption of ASC 842. In addition, the Company elected the package of practical expedients permitted under the transition guidance within ASC 842, which among other things, does not require the Company to reassess whether existing contracts contain leases, classification of leases identified, nor classification and treatment of initial direct costs capitalized under ASC 840. The Company also elected the practical expedients to combine the lease and non-lease components. The Company did not elect the practical expedient to apply hindsight as part of the leases evaluation. Additionally, the Company elected the practical expedient under ASU No. 2018-01, "Leases (Topic 842): Land Easement Practical Expedient for Transition to Topic 842", which allows an entity to not reassess whether any existing land easements are or contain leases.

The majority of the Company’s global lease portfolio represents leases of real estate, such as manufacturing facilities, warehouses, and office buildings, while the remainder represents leases of

personal property, such as vehicle leases, manufacturing and IT equipment. The Company determines whether a contract is or contains a lease at contract inception. The majority of the Company's lease arrangements are comprised of fixed payments and a limited number of these arrangements include a variable payment component based on certain index fluctuations.

Adoption of ASC 842 resulted in the recording of lease right-of-use assets ("lease assets") and lease liabilities of approximately $104 million and $103 million, respectively, as of January 1, 2019. The adoption did not impact consolidated net earnings and had no impact on cash flows.

The changes made to our Consolidated Balance Sheet as of January 1, 2019 for the adoption of ASC 842 were as follows:

(in millions)	Balance at December 31, 2018		Adjustments due to ASC 842		Balance at January 1, 2019
Other non-current assets	$	502	$	104	$	606
Accounts payable and accrued expenses	$	2,144	$	23	$	2,167
Other non-current liabilities	$	357	$	80	$	437

In February 2018, the FASB issued ASU No. 2018-07, "Compensation - Stock Compensation (Topic 718)." It expands the scope of the employee share-based payments guidance, which currently only includes share-based payments issued to employees, to also include share-based payments issued to nonemployees for goods and services. This guidance is effective for interim and annual periods beginning after December 15, 2018. The Company adopted this guidance as of January 1, 2019 and there was no impact to the consolidated financial statements.

Accounting Standards Not Yet Adopted

In August 2018, the FASB issued ASU No. 2018-15, "Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40)." It requires implementation costs incurred by customers in cloud computing arrangements to be deferred and recognized over the term of the arrangement, if those costs would be capitalized by the customer in a software licensing arrangement under the internal-use software guidance (Subtopic 350-40). This guidance is effective for interim and annual periods beginning after December 15, 2019. Early adoption is permitted. The Company is currently assessing the impact of this guidance on its consolidated financial statements.

In August 2018, the FASB issued Accounting Standards Update ("ASU") No. 2018-14, "Compensation - Retirement Benefits - Defined Benefit Plans - General (Subtopic 715-20)." The new standard (i) requires the removal of disclosures that are no longer considered cost beneficial; (ii) clarifies specific requirements of certain disclosures; and (iii) adds new disclosure requirements, including the weighted average interest crediting rates for cash balance plans and other plans with promised interest crediting rates, and reasons for significant gains and losses related to changes in the benefit obligation. This guidance is effective for annual periods beginning after December 15, 2020 and early adoption is permitted. The Company is currently assessing the guidance and will include enhanced disclosures in the consolidated financial statements upon adoption.

In August 2018, the FASB issued ASU No. 2018-13, "Fair Value Measurement (Topic 820)." It removes disclosure requirements on fair value measurements including the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, the policy for timing of transfers between levels, and the valuation processes for Level 3 fair value measurements. It also amends and clarifies certain disclosures and adds new disclosure requirements including the changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements, and the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. This guidance is effective for interim and annual periods beginning

after December 15, 2019. An entity is permitted to early adopt any removed or modified disclosures and delay adoption of the additional disclosures until the effective date. The Company is currently assessing the guidance and does not expect this guidance to have a material impact on its consolidated financial statements.

In June 2016, the FASB issued ASU No. 2016-13, "Financial Instruments - Credit Losses (Topic 326)." It replaces the current incurred loss impairment method with a new method that reflects expected credit losses. Under this new model an entity would recognize an impairment allowance equal to its current estimate of credit losses on financial assets measured at amortized cost. This guidance is effective for fiscal years beginning after December 15, 2019, with early adoption permitted. The Company is currently evaluating the impact this guidance will have on its consolidated financial statements.

Revenue from Contract with Customer [Abstract]

Revenue from Contract with Customer

Revenue from Contracts with Customers

The Company manufactures and sells products, primarily to OEMs of light vehicles and, to a lesser extent, to other OEMs of commercial vehicles, off-highway vehicles, certain tier one vehicle systems suppliers and into the aftermarket. 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 606, "Revenue from Contracts with Customers", until volumes are contractually known. Revenue is recognized when performance obligations under the terms of a contract are satisfied, which generally occurs with the transfer of control of the Company's products. For most of the Company's products, transfer of control occurs upon shipment or delivery; however, a limited number of the Company's 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. The Company recorded a contract asset of $10 million and $11 million at June 30, 2019 and December 31, 2018, respectively, for these arrangements. These amounts are reflected in Prepayments and other current assets in the Condensed Consolidated Balance Sheet.

Revenue is measured at the amount of consideration the Company expects to receive in exchange for transferring the goods. 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 limited 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. As a result of these arrangements, the Company recognized a liability of $3 million and $6 million at June 30, 2019 and December 31, 2018. These amounts are reflected in Accounts payable and accrued expenses in the Condensed Consolidated Balance Sheet.

The Company’s payment terms with customers are customary and vary by customer and geography but typically range from 30 to 90 days. The Company has evaluated the terms of its arrangements and determined that they do not contain significant financing components. The Company provides warranties on some of its products. Provisions for estimated expenses related to product warranty are made at the time products are sold. Refer to Note 9, "Product Warranty," to the Condensed Consolidated Financial Statements for more information. 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 606 and accounts for shipping and handling activities as a fulfillment cost.

In limited instances, certain customers have provided payments in advance of receiving related products, typically at the onset of an arrangement prior to the beginning of production. These contract liabilities are reflected as Accounts payable and accrued expenses and Other non-current liabilities in the

Condensed Consolidated Balance Sheet and were $11 million and $16 million at June 30, 2019 and $13 million and $17 million at December 31, 2018, respectively. These amounts are reflected as revenue over the term of the arrangement (typically 3 to 7 years) as the underlying products are shipped.

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, when the 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 3 to 7 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. The Company had $28 million and $29 million recorded in Prepayments and other current assets in the Condensed Consolidated Balance Sheet at June 30, 2019 and December 31, 2018, respectively. The Company had $187 million recorded in Other non-current assets in the Condensed Consolidated Balance Sheet at June 30, 2019 and December 31, 2018.

The Company's business is comprised of two reporting segments: Engine and Drivetrain. Refer to Note 21, "Reporting Segments," to the Condensed Consolidated Financial Statements for more information. The following table represents a disaggregation of revenue from contracts with customers by segment and region:

Research and Development Expenditures

Research and Development Expenditures

The Company's net Research & Development ("R&D") expenditures are included in selling, general and administrative expenses of the Condensed Consolidated Statements of Operations. Customer reimbursements are netted against gross R&D expenditures as they are considered a recovery of cost. Customer reimbursements for prototypes are recorded net of prototype costs based on customer contracts, typically either when the prototype is shipped or when it is accepted by the customer. Customer reimbursements for engineering services are recorded when performance obligations are

satisfied in accordance with the contract. Financial risks and rewards transfer upon shipment, acceptance of a prototype component by the customer or upon completion of the performance obligation, as stated in the respective customer agreement.

The following table presents the Company’s gross and net expenditures on R&D activities:

	Three Months Ended June 30,						Six Months Ended June 30,

Income Taxes

Income Taxes

The Company's provision for income taxes is based upon an estimated annual tax rate for the year applied to federal, state and foreign income. On a quarterly basis, the annual effective tax rate is adjusted, as appropriate, based upon changed facts and circumstances, if any, as compared to those forecasted at the beginning of the fiscal year and each interim period thereafter.

The Company's effective tax rate for the six months ended June 30, 2019 was 31.7%. This rate includes reductions of income tax expense of $7 million related to restructuring expense, $6 million related to other postretirement expense, and $5 million related to other one-time adjustments. This rate also includes an increase in income tax expense of $22 million due to the U.S. Department of the Treasury's issuance of the final regulations in the first quarter of 2019 related to the calculation of the one-time transition tax.

The Company's effective tax rate for the six months ended June 30, 2018 was 19.4%. This rate includes income tax expense of $1 million related to a commercial settlement gain, and reductions of income tax expense of $8 million related to restructuring expense, $13 million related to adjustments to measurement period provisional estimates associated with the Tax Cuts and Jobs Act of 2017, $21 million related to an increase to our deferred tax asset due to the Company's ability to record a tax benefit for certain foreign tax credits now available due to actions the Company took in the second quarter, and $10 million for other one-time tax adjustments.

The annual effective tax rates differ from the U.S. statutory rate primarily due to foreign rates which differ from those in the U.S., U.S. taxes on foreign earnings, the realization of certain business tax credits, including foreign tax credits, and favorable permanent differences between book and tax treatment for certain items, including equity in affiliates' earnings.

Product Warranties Disclosures [Abstract]

Product Warranty

Product Warranty

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. Management believes that the warranty accrual is appropriate; however, actual claims incurred could differ from the original estimates, requiring adjustments to the accrual.

The following table summarizes the activity in the product warranty accrual accounts:

In July 2016, the Company terminated interest rate swaps which had the effect of converting $384 million of fixed rate notes to variable rates. The gain on the termination was recorded as an increase to the notes and is being amortized as a reduction to interest expense over the remaining terms of the notes. The unamortized gain related to these swap terminations was $1 million and $2 million as of June 30, 2019 and December 31, 2018, respectively, on the 4.625% notes.

The weighted average interest rate on short-term borrowings outstanding as of June 30, 2019 and December 31, 2018 was 3.4% and 4.3%, respectively. The weighted average interest rate on all borrowings outstanding, including the effects of outstanding swaps, as of June 30, 2019 and December 31, 2018 was 3.4%.

The Company has a $1.2 billion multi-currency revolving credit facility, which includes a feature that allows the Company's facility to be increased to $1.5 billion with approval of the bank group. The facility provides for borrowings through June 29, 2022. The Company has one key financial covenant as part of the credit agreement which is a debt to Earnings Before Interest, Taxes, Depreciation and Amortization ("EBITDA ") ratio. The Company was in compliance with the financial covenant at June 30, 2019. At June 30, 2019 and December 31, 2018, the Company had no outstanding borrowings under this facility.

The Company's commercial paper program allows the Company to issue short-term, unsecured commercial paper notes up to a maximum aggregate principal amount outstanding of $1.2 billion. Under this program, the Company may issue notes from time to time and use the proceeds for general corporate purposes. The Company had no outstanding borrowings under this program as of June 30, 2019 and December 31, 2018.

The total current combined borrowing capacity under the multi-currency revolving credit facility and commercial paper program cannot exceed $1.2 billion.

As of June 30, 2019 and December 31, 2018, the estimated fair values of the Company’s senior unsecured notes totaled $2,142 million and $2,058 million, respectively. The estimated fair values were $82 million more than their carrying value at June 30, 2019 and $8 million less than their carrying value

at December 31, 2018. Fair market values of the senior unsecured notes are developed using observable values for similar debt instruments, which are considered Level 2 inputs as defined by ASC 820. The carrying values of the Company's multi-currency revolving credit facility and commercial paper program approximates fair value. The fair value estimates do not necessarily reflect the values the Company could realize in the current markets.

The Company had outstanding letters of credit of $38 million and $43 million at June 30, 2019 and December 31, 2018, respectively. The letters of credit typically act as guarantees of payment to certain third parties in accordance with specified terms and conditions.

Fair Value Disclosures [Abstract]

Fair Value Measurements

Fair Value Measurements

ASC 820 emphasizes that fair value is a market-based measurement, not an entity specific measurement. Therefore, a fair value measurement should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering market participant assumptions in fair value measurements, ASC 820 establishes a fair value hierarchy, which prioritizes the inputs used in measuring fair values as follows:

Level 1: Observable inputs such as quoted prices for identical assets or liabilities in active markets;

Level 2: Inputs, other than quoted prices in active markets, that are observable either directly or indirectly; and

Level 3: Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions.

Assets and liabilities measured at fair value are based on one or more of the following three valuation techniques noted in ASC 820:

A. Market approach: Prices and other relevant information generated by market transactions involving identical or comparable assets, liabilities or a group of assets or liabilities, such as a business.

B. Cost approach: Amount that would be required to replace the service capacity of an asset (replacement cost).

C. Income approach: Techniques to convert future amounts to a single present amount based upon market expectations (including present value techniques, option-pricing and excess earnings models).

The following tables classify assets and liabilities measured at fair value on a recurring basis as of June 30, 2019 and December 31, 2018:

			Basis of fair value measurements

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Financial Instruments

Financial Instruments

The Company’s financial instruments include cash and marketable securities. Due to the short-term nature of these instruments, their book value approximates their fair value. The Company’s financial instruments may include long-term debt, interest rate and cross-currency swaps, commodity derivative contracts and foreign currency derivative contracts. All derivative contracts are placed with counterparties that have an S&P, or equivalent, investment grade credit rating at the time of the contracts’ placement. At June 30, 2019 and December 31, 2018, the Company had no derivative contracts that contained credit risk related contingent features.

The Company uses certain commodity derivative contracts to protect against commodity price changes related to forecasted raw material and component purchases. The Company primarily utilizes forward and option contracts, which are designated as cash flow hedges. At June 30, 2019 and December 31, 2018, the following commodity derivative contracts were outstanding:

	Commodity derivative contracts
Commodity	Volume hedged June 30, 2019	Volume hedged December 31, 2018	Units of measure	Duration
Copper	120	257	Metric Tons	Dec - 19

The Company manages its interest rate risk by balancing its exposure to fixed and variable rates while attempting to optimize its interest costs. The Company selectively uses interest rate swaps to reduce market value risk associated with changes in interest rates (fair value hedges). At June 30, 2019 and December 31, 2018, the Company had no outstanding interest rate swaps.

The Company uses foreign currency forward and option contracts to protect against exchange rate movements for forecasted cash flows, including capital expenditures, purchases, operating expenses or sales transactions designated in currencies other than the functional currency of the operating unit. In addition, the Company uses foreign currency forward contracts to hedge exposure associated with our net investment in certain foreign operations (net investment hedges). The Company has also designated its Euro denominated debt as a net investment hedge of the Company's investment in a European subsidiary. Foreign currency derivative contracts require the Company, at a future date, to either buy or sell foreign currency in exchange for the operating units’ local currency. At June 30, 2019 and December 31, 2018, the following foreign currency derivative contracts were outstanding:

Effectiveness for cash flow hedges is assessed at the inception of the hedging relationship and quarterly, thereafter. Gains and losses arising from these contracts that are included in the assessment of effectiveness are deferred into accumulated other comprehensive income (loss) ("AOCI") and reclassified into income as the underlying operating transactions are recognized. These realized gains or losses offset the hedged transaction and are recorded on the same line in the statement of operations. The initial value of any component excluded from the assessment of effectiveness will be recognized in income using a systematic and rational method over the life of the hedging instrument. Any difference between the change in fair value of the excluded component and amounts recognized in income under that systematic and rational method will be recognized in AOCI.

Effectiveness for net investment hedges is assessed at the inception of the hedging relationship and quarterly, thereafter. Gains and losses arising from these contracts that are included in the assessment of effectiveness are deferred into foreign currency translation adjustments and only released when the subsidiary being hedged is sold or substantially liquidated. The initial value of any component excluded from the assessment of effectiveness will be recognized in income using a systematic and rational method over the life of the hedging instrument. Any difference between the change in fair value of the excluded component and amounts recognized in income under that systematic and rational method will be recognized in AOCI.

The table below shows deferred gains (losses) reported in AOCI as well as the amount expected to be reclassified to income in one year or less. The amount expected to be reclassified to income in one year or less assumes no change in the current relationship of the hedged item at June 30, 2019 market rates.

Retirement Benefits [Abstract]

Retirement Benefit Plans

Retirement Benefit Plans

The Company has a number of defined benefit pension plans and other postretirement benefit plans covering eligible salaried and hourly employees and their dependents. The estimated contributions to the Company's defined benefit pension plans for 2019 range from $15 million to $25 million, of which $8 million has been contributed through the first six months of the year. The other postretirement benefit plans, which provide medical and life insurance benefits, are unfunded plans.

During the three months ended June 30, 2019, the Company settled approximately $50 million of its pension projected benefit obligation by liquidating approximately $50 million in plan assets through a lump-sum disbursement made to an insurance company. Pursuant to this agreement, the insurance company unconditionally and irrevocably guarantees all future payments to certain participants that were receiving payments from the U.S. pension plan. The insurance company assumes all investment risk associated with the assets that were delivered as part of this transaction. Additionally, during the three months ended June 30, 2019, the Company discharged certain U.S. pension plan obligations by making lump-sum payments of $13 million to former employees of the Company. As a result, the Company settled $63 million of projected benefit obligation by liquidating pension plan assets and recorded a non-cash settlement loss of $26 million related to the accelerated recognition of unamortized losses.

The components of net periodic benefit cost recorded in the Condensed Consolidated Statements of Operations are as follows:

Stock-Based Compensation

Stock-Based Compensation

The Company has granted restricted common stock and restricted stock units (collectively, "restricted stock") and performance share units as long-term incentive awards to employees and non-employee directors under the BorgWarner Inc. 2014 Stock Incentive Plan, as amended ("2014 Plan") and the BorgWarner Inc. 2018 Stock Incentive Plan ("2018 Plan"). The Company's Board of Directors adopted the 2018 Plan as a replacement to the 2014 Plan in February 2018, and the Company's stockholders approved the 2018 Plan at the annual meeting of stockholders on April 25, 2018. After stockholders approved the 2018 Plan, the Company could no longer make grants under the 2014 Plan. The shares that were available for issuance under the 2014 Plan were cancelled upon approval of the 2018 Plan. The 2018 Plan authorizes the issuance of a total of 7 million shares, of which approximately 6 million shares were available for future issuance as of June 30, 2019.

Restricted stock In the first six months of 2019, the Company granted restricted stock in the amounts of 1,031,513 shares and 23,880 shares to employees and non-employee directors, respectively. Restricted stock granted to employees generally vests 50% after two years and the remainder after three years. Restricted stock granted to non-employee directors generally vests on the first anniversary of the date of grant. The Company recognizes the value of the restricted stock, which is equal to the market value of the Company’s common stock on the date of grant, as compensation expense ratably over the restricted stock's vesting period. As of June 30, 2019, the Company had $53 million of unrecognized compensation expense that will be recognized over a weighted average period of 2.1 years. The

Company recorded restricted stock compensation expense of $7 million and $5 million for the three months ended June 30, 2019 and 2018, respectively, and $14 million and $12 million for the six months ended June 30, 2019 and 2018, respectively.

A summary of the Company’s nonvested restricted stock for the six months ended June 30, 2019 is as follows:

	Shares subject to restriction (thousands)		Weighted average grant date fair value
Nonvested at December 31, 2018	1,516		$	42.97
Granted	930		$	41.92
Vested	(665	)	$	35.94
Forfeited	(6	)	$	45.41
Nonvested at March 31, 2019	1,775		$	44.77
Granted	125		$	40.78
Vested	(28	)	$	50.43
Forfeited	(37	)	$	45.13
Nonvested at June 30, 2019	1,835		$	44.40

Total Stockholder Return Performance Share Units The Company grants performance share units to members of senior management that vest at the end of three-year periods based on the Company's total stockholder return relative to a peer group of companies. The Company recorded compensation expense of $3 million and $2 million for the six months ended June 30, 2019 and 2018, respectively.

A summary of the status of the Company’s nonvested total stockholder return performance share units for the six months ended June 30, 2019 is as follows:

	Number of shares (thousands)		Weighted average grant date fair value
Nonvested at December 31, 2018	297		$	60.35
Granted	190		$	51.52
Forfeited	(9	)	$	55.30
Nonvested at March 31, 2019	478		$	56.93
Granted	5		$	51.59
Forfeited	(56	)	$	55.67
Nonvested at June 30, 2019	427		$	57.03

Relative Revenue Growth Performance Share Units The Company also grants performance share units to members of senior management that vest based on the Company's revenue growth relative to the vehicle market over three-year performance periods. The Company recorded compensation expense of $1 million for both of the three months ended June 30, 2019 and 2018 and $8 million for the six months ended June 30, 2018.

A summary of the status of the Company’s nonvested relative revenue growth performance share units for the six months ended June 30, 2019 is as follows:

	Number of shares (thousands)		Weighted average grant date fair value
Nonvested at December 31, 2018	297		$	47.03
Granted	190		$	41.90
Forfeited	(9	)	$	44.12
Nonvested at March 31, 2019	478		$	45.04
Granted	5		$	41.92
Forfeited	(56	)	$	44.24
Nonvested at June 30, 2019	427		$	45.11

In 2018, the Company modified the vesting provisions of restricted stock and performance share unit grants made to certain retiring executive officers to allow certain of the outstanding awards, that otherwise would have been forfeited, to vest upon retirement. This resulted in net restricted stock and performance share unit compensation expense of $2 million in the six months ended June 30, 2019 and a net reduction to expense of $4 million in the six months ended June 30, 2018, respectively.

Leases

Leases [Abstract]

Leases of Lessee Disclosure

Leases

The majority of the Company's global lease portfolio represents leases of real estate, such as manufacturing facilities, warehouses, and office buildings, while the remainder represents leases of personal property, such as vehicle leases, manufacturing and IT equipment. Most of the leases are operating leases with options to renew, with renewal terms that can extend the lease term from 1 to 5 years. The option to renew is included in the lease term if it is reasonably certain that the Company will exercise that option. Certain leases also include options to terminate or purchase the leased asset. The depreciable life of assets and leasehold improvements are limited by the expected lease term, unless there is a transfer of title or purchase option that is reasonably certain of exercise. The amount recognized in lease assets and liabilities for lease arrangements that include an option for renewal or early termination that is reasonably certain of being exercised is immaterial. The Company's lease agreements do not contain any material residual value guarantee or material restrictive covenants. The Company's policy is to account for the lease and non-lease components as a single lease component for all asset classes.

ASC 842 requires that the rate implicit in the lease be used if readily determinable. Generally, implicit rates are not readily determinable in the Company's contracts and the incremental borrowing rate is used for each lease arrangement. The incremental borrowing rates are determined using rates specific to the term of the lease, economic environments where lease activity is concentrated, value of lease portfolio, and assuming full collateralization of the loans.

All leases with an initial term of 12 months or less that do not include an option to extend or purchase the underlying asset that the Company is reasonably certain to exercise ("short-term leases") are not recorded on the consolidated balance sheet and lease expense is recognized on a straight-line basis over the lease term.

The following table presents the operating lease assets and lease liabilities as of June 30, 2019:

(in millions)		June 30, 2019
Assets
Operating lease assets	Other non-current assets	$	95
Total operating lease assets		$	95
Liabilities
Current
Operating lease liabilities	Accounts payable and accrued expenses	$	22
Noncurrent
Operating lease liabilities	Other non-current liabilities	71
Total operating lease liabilities		$	93

In the three and six months ended June 30, 2019, the Company recorded operating lease cost of $6 million and $13 million, respectively, reflected in Selling, general and administrative expenses in the Condensed Consolidated Statement of Operations. The finance lease cost including amortization of leased assets and interest on lease liabilities was less than $1 million in the six months ended June 30, 2019. Variable costs for the six months ended June 30, 2019 are immaterial, and the Company does not have sublease income or gains/losses on sale leaseback transactions.

The following table presents the maturity of lease liabilities as of June 30, 2019:

Commitments and Contingencies Disclosure [Abstract]

Contingencies

Contingencies

The Company's environmental and product liability contingencies are discussed separately below. In the normal course of business, the Company is also party to various other commercial and legal claims, actions and complaints, including matters involving warranty claims, intellectual property claims, general liability and various other risks. It is not possible to predict with certainty whether or not the Company will ultimately be successful in any of these other commercial and legal matters or, if not, what the impact might be. The Company's management does not expect that an adverse outcome in any of these other commercial and legal claims, actions and complaints will have a material adverse effect on the Company's results of operations, financial position or cash flows, although it could be material to the results of operations in a particular quarter.

Environmental

The Company and certain of its current and former direct and indirect corporate predecessors, subsidiaries and divisions have been identified by the United States Environmental Protection Agency and certain state environmental agencies and private parties as potentially responsible parties (“PRPs”) at various hazardous waste disposal sites under the Comprehensive Environmental Response, Compensation and Liability Act (“Superfund”) and equivalent state laws. The PRPs may currently be liable for the cost of clean-up and other remedial activities at 27 such sites. Responsibility for clean-up and other remedial activities at a Superfund site is typically shared among PRPs based on an allocation formula.

The Company believes that none of these matters, individually or in the aggregate, will have a material adverse effect on its results of operations, financial position or cash flows. Generally, this is because either the estimates of the maximum potential liability at a site are not material or the liability will be shared with other PRPs, although no assurance can be given with respect to the ultimate outcome of any such matter.

The Company has an accrual for environmental liabilities of $8 million and $9 million as of June 30, 2019 and December 31, 2018, respectively. This accrual is based on information available to the Company (which in most cases includes an estimate of allocation of liability among PRPs; the probability that other PRPs, many of whom are large, solvent public companies, will fully pay the cost apportioned to them; currently available information from PRPs and/or federal or state environmental agencies concerning the scope of contamination and estimated remediation and consulting costs; and remediation alternatives).

Like many other industrial companies that have historically operated in the United States, the Company, or parties that the Company is obligated to indemnify, continues to be named as one of many defendants in asbestos-related personal injury actions. The Company vigorously defends against these claims, and has been successful in obtaining the dismissal of the majority of the claims asserted against it without any payment. Due to the nature of the fibers used in certain types of automotive products, the encapsulation of the asbestos, and the manner of the products’ use, the Company believes that these products were and are highly unlikely to cause harm.  Furthermore, the useful life of nearly all of these products expired many years ago. The Company likewise expects that no payment on these claims will be made by the Company or its insurance carriers in the vast majority of current and future asbestos-related claims. 

The Company’s asbestos-related claims activity during the six months ended June 30, 2019 and 2018 is as follows:

	2019		2018
Beginning Claims January 1	8,598		9,225
New Claims Received	1,111		1,020
Dismissed Claims	(793	)	(786	)
Settled Claims	(154	)	(189	)
Ending Claims June 30	8,762		9,270

From the mid-2000s through June 30, 2019 and December 31, 2018, the Company incurred $596 million and $574 million, respectively, in asbestos-related claim resolution costs (including settlement payments and judgments) and associated defense costs. During the six months ended June 30, 2019 and 2018, the Company paid $15 million and $28 million, respectively, in asbestos-related claim resolution costs and associated defense costs. These gross payments are before tax benefits and any potential insurance receipts. Asbestos-related claim resolution costs and associated defense costs are reflected in the Company's operating cash flows.

The Company reviews, on an ongoing basis, its own experience in handling asbestos-related claims and trends affecting asbestos-related claims in the U.S. tort system generally, for the purposes of assessing the value of pending asbestos-related claims and the number and value of those that may be asserted in the future, as well as potential recoveries from the Company’s insurance carriers with respect to such claims and defense costs. The Company has accrued estimated amounts in its consolidated financial statements on account of asbestos-related claims that have been asserted but not yet resolved and for claims that have not yet been asserted. The Company's estimate of asbestos-related claim resolution costs and associated defense costs is not discounted to present value and includes an estimate of liability for potential future claims not yet asserted through December 31, 2064 with a runoff through 2074. The Company currently believes that December 31, 2074 is a reasonable assumption as to the last date on which it is likely to have resolved all asbestos-related claims, based on the nature and useful life of the Company’s products and the likelihood of incidence of asbestos-related disease in the U.S. population generally. As of June 30, 2019 and June 30, 2018, the Company’s reasonable best estimate of the aggregate liability for both asbestos-related claims asserted but not yet resolved and potential asbestos-related claims not yet asserted, including estimated defense costs, is as follows:

(in millions)	2019			2018
Beginning asbestos liability as of January 1	$	805		$	828
Claim resolution costs and associated defense costs	(22		)	(28		)
Ending asbestos liability as of June 30	$	783		$	800

The Company’s estimate of the claim resolution costs and associated defense costs for asbestos-related claims asserted but not yet resolved and potential claims not yet asserted is its reasonable best estimate of such costs. Such estimate is subject to numerous uncertainties. These include future legislative or judicial changes affecting the U.S. tort system, bankruptcy proceedings involving one or more co-defendants, the impact and timing of payments from bankruptcy trusts that currently exist and those that may exist in the future, disease emergence and associated claim filings, the impact of future settlements or significant judgments, changes in the medical condition of claimants, changes in the treatment of asbestos-related disease, and any changes in settlement or defense strategies. The balances recorded for asbestos-related claims are based on the best available information and assumptions that the Company believes are reasonable, including as to the number of future claims that may be asserted, the percentage of claims that may result in a payment, the average cost to resolve such claims, and potential defense costs. The Company has concluded that it is reasonably possible that it may incur additional losses through 2074 for asbestos-related claims, in addition to amounts recorded, of up to approximately $100 million as of June 30, 2019 and December 31, 2018. The various assumptions utilized in arriving at the Company’s estimate may also change over time, and the Company’s actual liability for asbestos-related claims asserted but not yet resolved and those not yet asserted may be higher or lower than the Company’s estimate as a result of such changes.

The Company has certain insurance coverage applicable to asbestos-related claims including primary insurance and excess insurance coverage.  Prior to June 2004, claim resolution costs and defense costs associated with all asbestos-related claims were paid by the Company's primary layer insurance carriers under a series of interim funding arrangements. In June 2004, primary layer insurance carriers notified the Company of the alleged exhaustion of their policy limits. A declaratory judgment action was filed in January 2004 in the Circuit Court of Cook County, Illinois by Continental Casualty Company and related companies against the Company and certain of its historical general liability insurance carriers. The Cook County court has issued a number of interim rulings, and discovery is continuing in this proceeding. The Company is vigorously pursuing the litigation against all insurance carriers that continue to be parties to it, which currently includes excess insurance carriers, as well as pursuing settlement discussions with its insurance carriers where appropriate. The Company has entered into settlement agreements with certain of its insurance carriers, resolving such insurance carriers’ coverage disputes through the insurance carriers’ agreement to pay specified amounts to the Company, either immediately or over a specified period. Through June 30, 2019 and December 31, 2018, the Company received $272 million and $271 million, respectively, in cash and notes from insurance carriers on account of asbestos-related claim resolution costs and associated defense costs.

As of June 30, 2019 and December 31, 2018, the Company estimates that it has $386 million in aggregate insurance coverage available with respect to asbestos-related claims, and their associated defense costs. The Company has recorded this insurance coverage as a long-term receivable for asbestos-related claim resolution costs and associated defense costs that have been incurred, less cash and notes received, and remaining limits as a deferred insurance asset with respect to liabilities recorded for potential future costs for asbestos-related claims. The Company has determined the amount of that estimate by taking into account the remaining limits of the insurance coverage, the number and amount of potential claims from co-insured parties, potential remaining recoveries from insolvent insurance carriers, the impact of previous insurance settlements, and coverage available from solvent insurance carriers not party to the coverage litigation. The Company’s estimated remaining insurance coverage relating to asbestos-related claims and their associated defense costs is the subject of disputes with its insurance carriers, substantially all of which are being adjudicated in the Cook County insurance litigation. The Company believes that its insurance receivable is probable of collection notwithstanding those disputes based on, among other things, the arguments made by the insurance carriers in the Cook County litigation and evaluation of those arguments by the Company and its counsel, the case law applicable to the issues in dispute, the rulings to date by the Cook County court, the absence of any credible evidence alleged by the insurance carriers that they are not liable to indemnify the Company, and the fact that the Company has recovered a substantial portion of its insurance coverage, 

$272 million, through June 30, 2019, from its insurance carriers under similar policies. However, the resolution of the insurance coverage disputes, and the number and amount of claims on our insurance from co-insured parties, may increase or decrease the amount of such insurance coverage available to the Company as compared to the Company’s estimate.

The amounts recorded in the Condensed Consolidated Balance Sheets respecting asbestos-related claims are as follows:

	June 30,		December 31,
(in millions)	2019		2018
Assets:
Other long-term asbestos-related insurance receivables	$	324	$	303
Deferred asbestos-related insurance asset	$	62	$	83

Liabilities:
Accounts payable and accrued expenses	$	49	$	50
Other non-current liabilities	734		755
Total accrued liabilities	$	783	$	805

On July 31, 2018, the Division of Enforcement of the Securities and Exchange Commission ("SEC") informed the Company that it is conducting an investigation related to the Company's accounting for asbestos-related claims not yet asserted. The Company is fully cooperating with the SEC in connection with its investigation.

Restructuring

Restructuring

In the third quarter of 2017, the Company initiated actions within its Engine segment designed to improve future profitability and competitiveness and started exploring strategic options for the non-core product lines. As a continuation of these actions, the Company recorded restructuring expense of $4 million and $11 million during the three and six months ended June 30, 2019, and $28 million and $33 million during the three and six months ended June 30, 2018, respectively, primarily related to professional fees and employee termination benefits. Additionally, in the first quarter of 2019, the Company initiated a separate voluntary termination program in the Engine segment and recorded restructuring expense of $7 million and $11 million in the three and six months ended June 30, 2019, respectively. The Company will continue its plan to improve the future profitability and competitiveness of its business in the Engine segment. These actions may result in the recognition of additional restructuring charges that could be material.

The Company recorded restructuring expense of $3 million in the six months ended June 30, 2019 related to Corporate restructuring activities.

Additionally, the Company recorded restructuring expense of $3 million and $6 million in the three and six months ended June 30, 2018, respectively, in the Drivetrain segment primarily related to manufacturing footprint rationalization activities.

Estimates of restructuring expense are based on information available at the time such charges are recorded. Due to the inherent uncertainty involved in estimating restructuring expenses, actual amounts paid for such activities may differ from amounts initially recorded. Accordingly, the Company may record revisions of previous estimates by adjusting previously established accruals.

The following tables display a rollforward of the severance accruals recorded within the Company's Condensed Consolidated Balance Sheet and the related cash flow activity for the three and six months ended June 30, 2019 and 2018:

Earnings Per Share [Abstract]

Earnings Per Share

Earnings Per Share

The Company presents both basic and diluted earnings per share of common stock (“EPS”). Basic EPS is calculated by dividing net earnings attributable to the Company by the weighted average shares of common stock outstanding during the reporting period. Diluted EPS is calculated by dividing net earnings attributable to the Company by the weighted average shares of common stock and common equivalent stock outstanding during the reporting period.

The dilutive impact of stock-based compensation is calculated using the treasury stock method. The treasury stock method assumes that the Company uses the assumed proceeds from the exercise of awards to repurchase common stock at the average market price during the period. The assumed proceeds under the treasury stock method include the purchase price that the grantee will pay in the future and compensation cost for future service that the Company has not yet recognized. The dilutive effects of performance-based stock awards described in the Note 14, "Stock-Based Compensation," to the Condensed Consolidated Financial Statements are included in the computation of diluted earnings per share at the level the related performance criteria are met through the respective balance sheet date.

The following table reconciles the numerators and denominators used to calculate basic and diluted earnings per share of common stock:

	Three Months Ended June 30,				Six Months Ended June 30,

Segment Reporting [Abstract]

Reporting Segments

Reporting Segments

The Company's business is comprised of two reporting segments: Engine and Drivetrain. These segments are strategic business groups that are managed separately as each represents a specific grouping of related automotive components and systems.

The Company allocates resources to each segment based upon the projected after-tax return on invested capital ("ROIC") of its business initiatives. Adjusted EBIT is comprised of earnings before interest, income taxes and noncontrolling interest (“EBIT") adjusted for restructuring, goodwill impairment charges, affiliates' earnings and other items not reflective of on-going operating income or loss ("Adjusted EBIT"). ROIC is comprised of Adjusted EBIT after deducting notional taxes compared to the projected average capital investment required.

Adjusted EBIT is the measure of segment income or loss used by the Company. The Company believes Adjusted EBIT is most reflective of the operational profitability or loss of our reporting segments. The following tables show segment information and Adjusted EBIT for the Company's reporting segments.

Recent Transactions

Romeo Power Technology

In May 2019, the Company invested $50 million, $46 million of which was paid in the second quarter of 2019, in exchange for a 20% equity interest in Romeo Power Technology ("Romeo") , a technology-leading battery module and pack supplier. The Company accounts for this investment in Series A-1 Preferred Stock of Romeo under the measurement alternative in ASC 321, "Investments - Equity Securities" for equity investments without a readily determinable fair value. Such investments are measured at cost, less any impairment, plus or minus changes resulting from observable price changes in orderly transactions for an identical or similar investment of the same issuer. Additionally, the Company and Romeo will form a new joint venture where the Company will own 60% interest. The joint venture will focus on producing battery module and pack technology.

Rinehart Motion Systems LLC and AM Racing LLC

On January 2, 2019, the Company acquired Rinehart Motion Systems LLC and AM Racing LLC, two established companies in the specialty electric and hybrid propulsion market, for approximately $15 million, of which $10 million was paid in the first quarter of 2019 and the remaining $5 million will be paid upon satisfaction of certain conditions.

The Company created Cascadia Motion LLC ("Cascadia Motion") to combine assets and operations of these two acquired companies. Based in Oregon, Cascadia Motion specializes in design, development and production of hybrid and electric propulsion solutions for prototype and low-volume production applications. It allows the Company to offer design, development and production of full electric and hybrid propulsion systems for niche and low-volume manufacturing applications.

In connection with the acquisition, the Company recognized intangible assets of $5 million, goodwill of $7 million within the Drivetrain reporting segment, and other assets and liabilities of $2 million to reflect the preliminary fair value of the assets acquired and liabilities assumed. The intangible assets will be amortized over a period of 2 to 15 years. Various valuation techniques were used to determine the fair value of the intangible assets, with the primary techniques being forms of the income approach, which use significant unobservable inputs, or Level 3 inputs, as defined by the fair value hierarchy. Under these valuation approaches, the Company is required to make estimates and assumptions about sales, operating margins, growth rates, royalty rates and discount rates based on budgets, business plans, economic projections, anticipated future cash flows and marketplace data. Due to the nature of the transaction, goodwill is not deductible for tax purposes.

The Company is in the process of finalizing all purchase accounting adjustments related to the acquisition of Cascadia Motion. Certain estimated values for the acquisition, including goodwill, intangible assets and deferred taxes, are not yet finalized, and the preliminary purchase price allocations are subject to change as the Company completes its analysis of the fair value as of the date of acquisition.

Due to its insignificant size relative to the Company, supplemental pro forma financial information of the combined entity for the current and prior reporting period is not provided.

Assets and Liabilities Held For Sale

In 2017, the Company started exploring strategic options for non-core product lines in the Engine segment, launched an active program to locate a buyer and initiated all other actions required to complete the plan to sell and exit the non-core pipe and thermostat product lines. During 2018, the Company continued its marketing efforts with interested parties and engaged in active discussions with these parties. In December 2018, after finalizing negotiations regarding various aspects of the sale, the Company entered into a definitive agreement to sell its thermostat product lines for approximately $28 million subject to customary adjustments. All closing conditions were satisfied, and the sale was closed on April 1, 2019. The Company received cash proceeds of $27 million in the six months ended June 30, 2019. Additionally, during the six months ended June 30, 2019, the Company entered into agreements to transition its pipes product lines to multiple buyers, for inconsequential proceeds. Based on the cash proceeds in conjunction with the closing of the transaction to sell the thermostat product lines, the Company determined no additional gain or loss on sale was required during the six months ended June 30, 2019. During the six months ended June 30, 2019, the assets and liabilities were removed from the Condensed Consolidated Balance Sheet. The business did not meet the criteria to be classified as a discontinued operation.

The Company is in the process of finalizing all purchase price adjustments related to the sale of non-core product lines. Subsequent adjustments may be necessary based on the finalization of this process.

The assets and liabilities classified as held for sale at December 31, 2018 were as follows:
