TRW Automotive Holdings Corp.

Notes to Unaudited Condensed Consolidated Financial Statements

1. Description of Business

        TRW Automotive Holdings Corp. (also referred to herein as the "Company") is among the world's largest and most diversified suppliers of automotive systems, modules and components to global automotive original equipment manufacturers ("OEMs") and related aftermarkets. The Company conducts substantially all of its operations through subsidiaries. These operations primarily encompass the design, manufacture and sale of active and passive safety related products and systems. Active safety related products and systems principally refer to vehicle dynamic controls (primarily braking and steering), and passive safety related products and systems principally refer to occupant restraints (primarily airbags and seat belts) and safety electronics (primarily electronic control units and crash and occupant weight sensors). The Company is primarily a "Tier 1" supplier (a supplier that sells to OEMs). In 2014, approximately 82% of the Company's end-customer sales were to major OEMs.

2. Merger

        On September 15, 2014, the Company entered into an Agreement and Plan of Merger (the "Merger Agreement") with ZF Friedrichshafen AG, a stock corporation organized and existing under the laws of the Federal Republic of Germany ("ZF"), and MSNA, Inc., a Delaware corporation ("Merger Sub") and a wholly owned subsidiary of ZF held directly by ZF North America, Inc. ("ZNA"), pursuant to which Merger Sub will be merged with and into the Company (the "ZF Merger") with the Company surviving the ZF Merger as an indirect wholly owned subsidiary of ZF. At a special stockholders meeting held on November 19, 2014, the Company's stockholders adopted the Merger Agreement.

        At the effective time of the ZF Merger, each share of the Company's common stock issued and outstanding (other than any shares of Company common stock held by ZF, ZNA, Merger Sub or any other wholly owned subsidiary of ZF, treasury shares held by the Company and shares owned by stockholders who have properly made and not withdrawn a demand for appraisal rights under Delaware law) will be converted into the right to receive $105.60 in cash, without interest (the "Merger Consideration"). In addition, at the effective time of the ZF Merger, (i) all then-outstanding Company stock options, restricted stock units ("RSUs"), phantom stock units ("PSUs") and performance share units ("Performance Units," which will vest at the "maximum level" of performance), whether vested or unvested, will be converted into the right to receive the Merger Consideration, less the exercise price of such awards, if any, and (ii) all then-outstanding Company stock-settled stock appreciation rights ("SSARs"), whether vested or unvested, will be converted into the right to receive an amount in cash equal to the excess of the lesser of the Merger Consideration and the "maximum value" of such stock appreciation right over the fair market value per share at the relevant grant date. The consummation of the ZF Merger is subject to the receipt of antitrust approvals in the United States and Mexico and other customary closing conditions. The transaction is expected to close by the end of the second quarter of 2015. If completed, the ZF Merger will result in the Company becoming a wholly owned subsidiary of ZF and its shares will no longer be listed on any public market.

3. Basis of Presentation

        These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2014, as amended, filed with the U.S. Securities and Exchange Commission ("SEC").

3. Basis of Presentation (Continued)

        These unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the SEC for interim financial information. Accordingly, they do not include all of the information and footnotes required by United States generally accepted accounting principles ("GAAP") for complete financial statements. These financial statements include all adjustments (consisting primarily of normal, recurring adjustments) considered necessary for a fair presentation of the financial position, results of operations and cash flows of the Company. Operating results for the three months ended April 3, 2015 are not necessarily indicative of results that may be expected for the year ending December 31, 2015.

        The Company follows a fiscal calendar that ends on December 31. However, each fiscal quarter has three periods consisting of one five week period and two four week periods. Each quarterly period ends on a Friday, with the possible exception of the final quarter of the year, which always ends on December 31.

        Earnings Per Share.    Basic earnings per share are calculated by dividing net earnings by the weighted average shares outstanding during the period. Diluted earnings per share reflect the weighted average impact of all potentially dilutive securities from the date of issuance, including stock options, RSUs, SSARs and Performance Units. Further, if the inclusion of shares potentially issuable for the Company's 3.50% exchangeable senior unsecured notes (see Note 12) is more dilutive than the inclusion of the interest expense for those exchangeable notes, the Company utilizes the "if-converted" method to calculate diluted earnings per share. Under the if-converted method, the Company adjusts net earnings to add back interest expense and amortization of the discount recognized on the exchangeable notes and includes the number of shares potentially issuable related to the exchangeable notes in the weighted average shares outstanding.

        If the average market price of the Company's common stock exceeds the exercise price of stock options outstanding or the fair value on the date of grant of the SSARs, the treasury stock method is used to determine the incremental number of shares to be included in the diluted earnings per share computation.

        Net earnings attributable to TRW and the weighted average shares outstanding used in calculating basic and diluted earnings per share were:

        For the three months ended April 3, 2015, no securities were anti-dilutive to earnings per share. For the three months ended March 28, 2014, approximately 1.0 million securities were excluded from the calculation of diluted earnings per share because the inclusion of such securities in the calculation would have been anti-dilutive.

        Warranties.    Product warranty liabilities are recorded based upon management estimates including such factors as the written agreement with the customer, the length of the warranty period, the historical performance of the product and likely changes in performance of newer products and the mix and volume of products sold. Product warranty liabilities are reviewed on a regular basis and adjusted to reflect actual experience.

        The following table presents the movement in the product warranty liability for the periods indicated:

	Three Months Ended

        Recently Adopted or Issued Accounting Pronouncements.    In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09, "Revenue from Contracts with Customers (Topic 606)," which provides a single revenue recognition model intended to improve comparability over a range of industries, companies and geographical boundaries and to enhance disclosures. The standard is effective retrospectively for fiscal years (and interim reporting periods within those years) beginning after December 15, 2016. Early adoption is not permitted. The Company continues to assess the potential impact on its operations and financial statements.

        In April 2015, the FASB issued ASU No. 2015-03, "Simplifying the Presentation of Debt Issuance Costs (Subtopic 835-30)," which requires debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The standard is effective retrospectively for fiscal years beginning after December 15, 2015, and interim periods within fiscal years beginning after December 15, 2016. Early adoption is permitted. When adopted, the implementation of this ASU will not have a material impact on the Company's consolidated financial statements.

4. Divestiture and Assets Held-For-Sale

Divestiture

        During the three months ended April 3, 2015, the Company closed the sale of its wholly owned engine valve subsidiaries which represented the material portion of the business to be divested. The closing did not include the transfer of several of the Company's joint ventures involved in the business which remain held-for-sale as of April 3, 2015. The engine valve business is reported within the Automotive Components segment (see Note 18). The Company received net cash proceeds of approximately $313 million and recognized a gain on sale of $186 million for this divestiture.

Notes to Unaudited Condensed Consolidated Financial Statements (Continued)

4. Divestiture and Assets Held-For-Sale (Continued)

Assets Held-For-Sale

        In response to the European Commission's conditional antitrust approval of the ZF Merger, the Company commenced the process of marketing its linkage and suspension business to potential qualified buyers. The linkage and suspension business is reported within the Chassis Systems segment (see Note 18). This business met the definition of held-for-sale, and as such, the assets and liabilities associated with the transaction are separately classified as held-for-sale in the condensed consolidated balance sheet as of April 3, 2015 and depreciation of long-lived assets has ceased. The divestiture did not meet the criteria for presentation as a discontinued operation.

        Subsequent to the end of the Company's first quarter, on April 21, 2015, the Company entered into a definitive agreement to divest its linkage and suspension business for a purchase price of $400 million in cash which is subject to adjustment in accordance with the agreement as of the closing date. The planned divestiture of the linkage and suspension business is expected to close by the end of the third quarter of 2015 and is subject to customary closing conditions, including regulatory approvals.

        The major classes of assets and liabilities held-for-sale, which includes the Company's linkage and suspension business and the engine valve joint ventures, were as follows:

	As of April 3, 2015
	(Dollars in millions)
Cash	$	13
Accounts receivable—net		75
Inventories		36
Prepaid expenses and other current assets		16
Property, plant and equipment—net		110

Total liabilities related to assets held-for-sale	$	113

        Earnings before income taxes for the Company's engine valve business, including wholly owned subsidiaries through the date of the divestiture and its linkage and suspension business, were as follows:

	Three Months Ended

	(Dollars in millions)
Finished products and work in process	$	464	$	470
Raw materials and supplies		514		502
Total inventories	$	978	$	972

6. Investment in Joint Venture Affiliate

        In 2014, the Company entered into a joint venture of which the Company owns a 30% share. This joint venture will construct and operate a casting foundry in order to supply castings to the Company's North American Braking operations through a long-term supply arrangement, which is deemed to contain an embedded lease arrangement.

        During the three months ended April 3, 2015, the Company made equity and working capital contributions of approximately $5 million. Including contributions made in 2014, the Company's total cash investment is approximately $21 million. For accounting purposes only, the Company is deemed to be the owner of the casting foundry during the construction period. Therefore, as of April 3, 2015, the Company recorded $58 million as construction-in-process and $41 million in long-term liabilities. The liability does not represent a legal obligation to pay cash.

        The Company adjusts its effective tax rate each quarter to be consistent with the estimated annual effective tax rate and records the tax impact of unusual or infrequently occurring items, including changes in judgment about valuation allowances and effects of changes in tax laws or rates, in the interim period in which they occur.

        Income tax expense for the three months ended April 3, 2015 was $144 million on pre-tax earnings of $521 million. Income tax expense for the three months ended March 28, 2014 was $78 million on pre-tax earnings of $287 million. For the period ended April 3, 2015, both income tax expense and pre-tax earnings include the impact of the gain on divestiture, which did not have a significant impact on the overall effective tax rate for the period. For the periods ended April 3, 2015 and March 28, 2014, the income tax rate varies from the United States statutory income tax rate primarily due to favorable foreign tax rates, holidays, and credits, as well as the effect of the gain on divestiture.

        The Company operates in multiple jurisdictions throughout the world and the income tax returns of several subsidiaries in various tax jurisdictions are currently under examination. Although it is not possible to predict the timing of the conclusions of all ongoing tax audits with accuracy, it is possible that some or all of these examinations will conclude within the next 12 months. It is also reasonably possible that certain statutes of limitations may expire relating to various foreign jurisdictions within the next 12 months. As such, it is possible that a change in the Company's gross unrecognized tax benefits may occur; however, it is not possible to reasonably estimate the potential change in gross unrecognized tax benefits.

11. Fair Value Measurements and Financial Instruments

        The inputs to valuation techniques used to measure fair value are prioritized into a three-level hierarchy. This hierarchy gives the highest priority to quoted prices in active markets for identical assets and liabilities and lowest priority to unobservable inputs, as follows:

Level 1.  Inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company can access at the measurement date.

Level 2.  Inputs are other than quoted prices that are observable for the asset or liability, either directly or indirectly.

Level 3.  Unobservable inputs are supported by little or no market activity. The unobservable inputs represent the Company's best assumptions of how market participants would price the assets or liabilities.

11. Fair Value Measurements and Financial Instruments (Continued)

Items Measured at Fair Value on a Recurring Basis

        The fair value measurements for assets and liabilities recognized in the Company's condensed consolidated balance sheets are as follows:

	As of
	April 3, 2015		December 31, 2014		Measurement Approach
	(Dollars in millions)
Foreign currency exchange contracts—current assets	$	38	$	7	Level 2
Foreign currency exchange contracts—noncurrent assets		23		2	Level 2
Foreign currency exchange contracts—current liability		14		13	Level 2
Foreign currency exchange contracts—noncurrent liability		14		13	Level 2

        The Company's foreign currency exchange contracts are recorded at fair value derived principally from or corroborated by observable market data under the market approach. Inputs include quoted prices for similar assets and liabilities (risk adjusted), and market-corroborated inputs, such as market comparables, interest rates, yield curves and other items that allow value to be determined. The Company uses quoted currency forward rates to calculate forward values, and then discounts the forward values. In addition, the Company's calculation of the fair value of its foreign currency option contracts uses quoted currency volatilities.

        The discount rates for all derivative contracts are based on quoted bank deposit rates. For contracts which, when aggregated by counterparty, are in a liability position, the rates are adjusted by the credit spread which market participants would apply if buying these contracts from the Company's counterparties.

        There were no changes in the Company's valuation techniques during the three months ended April 3, 2015.

Items Measured at Fair Value on a Nonrecurring Basis

        In addition to items that are measured at fair value on a recurring basis, we also have assets that may be measured at fair value on a nonrecurring basis. These assets include long-lived assets, intangible assets and investments in affiliates, which may be written down to fair value as a result of impairment.

        The Company has determined that the fair value measurements related to each of these assets rely primarily on Company-specific inputs and the Company's assumptions about the use of the assets, as observable inputs are not available. As such, the Company has determined that each of these fair value measurements reside within Level 3 of the fair value hierarchy. To determine the fair value of long-lived assets, the Company utilizes the projected cash flows expected to be generated by the long-lived assets, then discounts the future cash flows over the useful life of the long-lived assets by using a risk-adjusted rate for the Company. The Company records asset impairments associated with its determination of the fair value of its long-lived assets that exhibited indicators of impairment (see Note 13).

11. Fair Value Measurements and Financial Instruments (Continued)

Financial Instruments Not Carried at Fair Value

        The carrying value and estimated fair value of financial instruments that are not carried on the Company's balance sheet at fair value are as follows:

	As of
	April 3, 2015				December 31, 2014
	Carrying Value		Fair Value		Carrying Value		Fair Value		Measurement Approach
	(Dollars in millions)
Short-term debt, fixed and floating rate	$	264	$	264	$	222	$	222	Level 2
Fixed rate long-term debt	$	1,318	$	1,382	$	1,326	$	1,389	Level 2
Fixed rate exchangeable notes	$	12	$	45	$	30	$	109	Level 2

        The carrying value of short-term debt approximates fair value because of the short term nature of these instruments. The fair value of long term debt was determined primarily from quoted market prices, as provided by participants in the secondary marketplace. For long-term debt without a quoted market price, the Company estimates the fair value using discounted cash flow models with market based borrowing rates for similar types of arrangements.

Derivative Instruments and Hedging Activities

        The Company is exposed to fluctuations in foreign currency exchange rates, interest rates and commodity prices. The Company enters into derivative instruments primarily to hedge portions of its forecasted foreign currency denominated cash flows and designates these derivative instruments as cash flow hedges in order to qualify for hedge accounting. Certain foreign exchange contracts that do not qualify for hedge accounting are entered into to hedge recognized foreign currency transactions. All gains or losses on derivative instruments which are not designated for hedge accounting treatment or do not qualify for hedge accounting, or result from hedge ineffectiveness, are reported in earnings immediately.

        In addition, the Company is exposed to credit loss in the event of nonperformance by the counterparty to the derivative financial instruments. The Company attempts to limit this exposure by entering into agreements directly with a number of major financial institutions that meet the Company's credit standards and that are expected to fully satisfy their obligations under the contracts, and by monitoring the Company's credit exposure to each counterparty in light of its current credit quality.

        As of April 3, 2015, the Company had a notional value of $2.7 billion in foreign exchange contracts outstanding. These foreign exchange contracts mature at various dates through March 2018.

        Cash Flow Hedges.    For any derivative instrument that is designated and qualifies as a cash flow hedge, the effective portion of the gain or loss on the derivative is reported as a component of Other Comprehensive Income ("OCI"), and is subsequently reclassified into earnings in the period which the hedged transaction affects earnings. The earnings impact is reported either in sales, cost of sales, or other (income) expense—net, to match the underlying transaction. Gains and losses on the derivative representing either hedge ineffectiveness or hedge components excluded from the assessment of

17

TRW Automotive Holdings Corp.

Notes to Unaudited Condensed Consolidated Financial Statements (Continued)

11. Fair Value Measurements and Financial Instruments (Continued)

effectiveness are recognized in other (income) expense—net. Such amounts were immaterial for the three months ended April 3, 2015 and March 28, 2014.

        The effective portion of gains and losses on derivatives designated as cash flow hedges which were related to foreign currency exchange contracts and recognized in OCI was a gain of $50 million for the three months ended April 3, 2015, compared to a loss of $3 million for the three months ended March 28, 2014.

        The effective portion of gains and losses on cash flow hedges reclassified from OCI into the statement of earnings for the three months ended April 3, 2015 was a gain of $3 million, and was included in various line items on the statement of earnings, compared to a loss of $3 million for the three months ended March 28, 2014.

        Gains and losses reclassified into earnings include the discontinuance of cash flow hedges, which were immaterial for each of the three months ended April 3, 2015 and March 28, 2014. Approximately $19 million of gains, net of tax, which are included in OCI, are expected to be reclassified into earnings in the next twelve months.

        Undesignated Derivatives.    For the three months ended April 3, 2015, the Company recognized gains of $29 million in other (income) expense—net, for derivative instruments not designated as hedging instruments. For the three months ended March 28, 2014, the Company recognized losses of a de minimis amount in other (income) expense—net, for derivative instruments not designated as hedging instruments.

        Credit-Risk-Related Contingent Features.    The Company has entered into International Swaps and Derivatives Association ("ISDA") agreements with each of its significant derivative counterparties. These agreements provide bilateral netting and offsetting of accounts that are in a liability position with those that are in an asset position. These agreements do not require the Company to maintain a minimum credit rating in order to be in compliance with the terms of the agreements and do not contain any margin call provisions or collateral requirements that could be triggered by derivative instruments in a net liability position. These agreements provide for an additional termination event if the Company's Eighth Amended and Restated Credit Agreement dated September 28, 2012 (the "Eighth Credit Agreement") is terminated or a change of control occurs under the Eighth Credit Agreement. The ZF Merger, if consummated, is expected to cause an additional termination event under these agreements. The occurrence of an additional termination event would allow the Company and each of the counterparties to request cancellation and settlement of the mark-to-market position for any outstanding derivative contracts, regardless of the maturity date of the contract.

Offsetting of Derivative Assets and Liabilities

        The following table reflects the offsetting of derivative assets and liabilities:

	As of April 3, 2015							As of December 31, 2014
	Gross Amounts Recognized		Gross Amounts Offset			Net Amounts Reported		Gross Amounts Recognized		Gross Amounts Offset			Net Amounts Reported

Senior Notes

        4.45% Senior Notes.    In November 2013, the Company issued $400 million in aggregate principal amount of 4.45% senior unsecured notes due 2023 in a private placement. Interest is payable semi-annually on December 1 and June 1 of each year.

        4.50% Senior Notes.    In February 2013, the Company issued $400 million in aggregate principal amount of 4.50% senior unsecured notes due 2021 in a private placement. Interest is payable semi-annually on March 1 and September 1 of each year.

        7.25% Senior Notes.    In March 2007, the Company issued $600 million in aggregate principal amount of 7.25% senior unsecured notes due 2017 in a private placement. Interest is payable semi-annually on March 15 and September 15 of each year.

Exchangeable Senior Notes

        In November 2009, the Company issued approximately $259 million in aggregate principal amount of 3.50% exchangeable senior unsecured notes due December 1, 2015 (the "Exchangeable Senior Notes") in a private placement. By their terms, prior to September 1, 2015, the notes were exchangeable only upon specified events or conditions being met and, thereafter, at any time. The initial exchange rate was 33.8392 shares of the Company's common stock per $1,000 principal amount of notes.

        In the first quarter of 2015, in accordance with the Exchangeable Senior Note indenture, $18 million in principal amount of Exchangeable Senior Notes were exchanged for approximately 623,000 shares of common stock. A $1 million loss on retirement of debt was recorded relating to the write-off of a portion of debt issue costs and the debt discount, as well as a reduction of $46 million to

12. Debt (Continued)

paid-in-capital relating to the repurchase of the conversion feature of the Exchangeable Senior Notes. The repurchased notes were retired upon settlement.

        During March 2015, in accordance with provisions in the Exchangeable Senior Notes indenture, the Company provided to note holders a notice that it would optionally redeem all outstanding notes at par value, plus accrued interest, on April 9, 2015. Subsequent to quarter end, Exchangeable Senior Notes of approximately $13 million in principal amount, excluding $1 million of discount, were exchanged for 437,000 shares of common stock. On April 9, 2015, the Company redeemed the remaining notes outstanding of approximately $23,000 at par value, plus accrued interest.

Senior Credit Facilities

        The Eighth Credit Agreement provides for senior credit facilities consisting of (i) a revolving credit facility in the amount of $1.4 billion which matures in September 2017, subject to certain liquidity conditions being met in October 2016 (the "Revolving Credit Facility"), and (ii) additional availability which may be used in the future for one or more term loans or additional revolving facilities (together with the Revolving Credit Facility, the "Facilities"). All of the Facilities were undrawn as of April 3, 2015.

        The commitment fee and the applicable margin for borrowing on the Revolving Credit Facility are subject to a ratings-based grid. The applicable margin in effect as of April 3, 2015 was 0.25% with respect to base rate borrowings, 1.25% with respect to eurocurrency borrowings, and the commitment fee on the undrawn amounts under the Revolving Credit Facility was 0.25%.

Other Borrowings

        The Company has borrowings under uncommitted credit agreements in several of the countries in which it operates. The borrowings are from various individual banks at quoted market interest rates. As of April 3, 2015, the Company had short-term borrowings under uncommitted credit facilities totaling $264 million.

Debt Repurchases

        As market conditions warrant, the Company may from time to time repurchase debt securities issued by the Company or its subsidiaries, in privately negotiated or open market transactions, by tender offer, exchange offer, or by other means, or the Company may optionally redeem such debt securities.

Debt Covenants Potentially Impacted by the ZF Merger

        The ZF Merger, if consummated, is expected to cause a change of control triggering event as defined in the Company's respective Senior Note indentures. In general, upon the occurrence of a change of control triggering event under the Senior Note indentures, the Company is required to offer to repurchase the Senior Notes, for a certain period of time, at a price of 101% of par, plus accrued and unpaid interest. Additionally, if the ZF Merger is consummated, the Company anticipates terminating the Eighth Credit Agreement.

Ending balance	$	37		$	84

        Of the $37 million restructuring reserves as of April 3, 2015, approximately $27 million is expected to be paid in the remainder of 2015. The remaining balance is expected to be paid in 2016 to 2017 and is comprised primarily of involuntary employee termination arrangements in Europe.

14. Transaction Costs

        The Company incurred transaction and merger-related costs of $2 million for financial advisory and legal fees related to the ZF Merger (see Note 2) and divestiture activity (see Note 4) for the three months ended April 3, 2015.

TRW Automotive Holdings Corp.

Notes to Unaudited Condensed Consolidated Financial Statements (Continued)

15. Capital Stock

        The Company's authorized capital stock consists of (i) 500 million shares of common stock, par value $.01 per share (the "Common Stock"), of which 115,487,709 shares were issued and outstanding as of April 3, 2015, net of 4,668 shares of treasury stock withheld at cost to satisfy tax obligations for a specific grant under the Company's stock-based compensation plan; and (ii) 250 million shares of preferred stock, par value $.01 per share, including 500,000 shares of Series A junior participating preferred stock, of which no shares are currently issued or outstanding.

        From time to time, capital stock is issued in conjunction with the exercise of stock options and stock-settled stock appreciation rights and the vesting of restricted stock units issued as part of the Company's stock incentive plan (see Note 16).

        Share Repurchase Programs.    The Company has two share repurchase programs in place, consisting of a $2 billion program that extends through December 31, 2016 (the "$2 Billion Program"), and a program that is intended to offset, on an ongoing basis, the dilution created by the Company's stock incentive plan for up to 1.5 million shares in 2015 and each subsequent year (the "Anti-Dilution Program"). The Anti-Dilution program does not have an expiration date. The Company is not obligated to repurchase any shares under either program.

        Pursuant to the terms of the Merger Agreement with ZF, the Company is restricted from repurchasing additional shares of its common stock under the share repurchase programs without ZF's consent.

16. Share-Based Compensation and Cash Incentive Awards

Equity Awards

        As of April 3, 2015, the Company had 3,390,506 shares of Common Stock available for issuance under the TRW Automotive Holdings Corp 2012 Stock Incentive Plan (the "2012 Plan"). In addition, under the 2012 Plan and the Company's 2003 Stock Incentive Plan (as amended, the "2003 Plan" and, together with the 2012 Plan, the "Plan"), 195,496 stock options, 1,958,805 SSARs, 318,889 nonvested RSUs, 3,113 nonvested PSUs and nonvested Performance Units under which up to 70,425 shares may be issued (based on maximum performance thereunder) were outstanding as of April 3, 2015. Under the terms of the respective grants, all of the SSARs and stock options have an 8-year term and vest ratably over three years, substantially all of the RSUs vest ratably over three years, all of the PSUs vest ratably over three years and Performance Units cliff vest after their three-year performance period. As a result of changes to retirement provisions in the equity award agreements beginning in 2013, the Company applies a non-substantive vesting period approach for certain of the awards granted in 2014 and 2013 whereby expense is accelerated for those employees who receive awards and are eligible to retire prior to the award vesting.

Total share-based compensation expense	$	5	$	8

Potential Impact of the ZF Merger on Equity Awards

        If consummated, at the effective time of the ZF Merger, (i) all then-outstanding Company stock options, RSUs, PSUs and Performance Units (which will vest at the "maximum level" of performance), whether vested or unvested, will be converted into the right to receive the Merger Consideration, less the exercise price of such awards, if any, and (ii) all then-outstanding Company SSARs, whether vested or unvested, will be converted into the right to receive an amount in cash equal to the excess of the lesser of the Merger Consideration and the "maximum value" of such SSAR over the fair market value per share at the relevant grant date.

Cash Incentive Awards

        On February 12, 2015, the Company issued cash incentive awards to executive officers and certain employees of the Company. Each award is divided into three tranches of equal value with a tranche vesting on each of the first, second and third anniversaries of the grant date. The aggregate value of the awards is approximately $33 million. The Company applies a non-substantive vesting period approach whereby expense is accelerated for those employees who receive awards and are eligible to retire prior to the award vesting. For the three months ended April 3, 2015, the Company recognized approximately $2 million of compensation expense and corresponding liability related to these awards.

17. Contingencies

        Various claims, lawsuits and administrative proceedings are pending or threatened against the Company or its subsidiaries, covering a wide range of matters that arise in the ordinary course of the Company's business activities with respect to commercial, patent, product liability, environmental and occupational safety and health law matters. In addition, the Company and its subsidiaries are conducting a number of environmental investigations and remedial actions at current and former locations of certain of the Company's subsidiaries. Along with other companies, certain subsidiaries of the Company have been named potentially responsible parties for certain waste management sites. Each of these matters is subject to various uncertainties, and some of these matters may be resolved unfavorably with respect to the Company or the relevant subsidiary. A reserve estimate for each environmental matter is established using standard engineering cost estimating techniques on an undiscounted basis. In the determination of such costs, consideration is given to the professional judgment of Company environmental engineers, in consultation with outside environmental specialists,

23

TRW Automotive Holdings Corp.

Notes to Unaudited Condensed Consolidated Financial Statements (Continued)

17. Contingencies (Continued)

when necessary. At multi-party sites, the reserve estimate also reflects the expected allocation of total project costs among the various potentially responsible parties.

        As of April 3, 2015, the Company had reserves for environmental matters of $70 million. In addition, the Company has established a receivable for a portion of this environmental liability as a result of its right to indemnification for 50% of any environmental liabilities associated with the operation or ownership of the Company's automotive business existing at or prior to March 2003. The Company believes any liability, in excess of amounts accrued in its financial statements, that may result from the resolution of environmental matters for which sufficient information is available to support these cost estimates, will not have a material adverse effect on the Company's financial position, results of operations or cash flows.

        The Company faces an inherent business risk of exposure to product liability, recall and warranty claims in the event that its products actually or allegedly fail to perform as expected or the use of its products results, or is alleged to result, in bodily injury and/or property damage. Accordingly, the Company could experience material warranty, recall or product liability losses in the future. For further information, including quantification of the Company's product warranty liability, see the description of "Warranties" in Note 3.

        While certain of the Company's subsidiaries have been subject in recent years to asbestos-related claims, management believes that such claims will not have a material adverse effect on the Company's financial statements. In general, these claims seek damages for illnesses alleged to have resulted from exposure to asbestos used in certain components sold in the past by the Company's subsidiaries. Management believes that the majority of the claimants were vehicle mechanics. The vast majority of these claims name as defendants numerous manufacturers and suppliers of a variety of products allegedly containing asbestos. Management believes that, to the extent any of the products sold by the Company's subsidiaries and at issue in these cases contained asbestos, the asbestos was encapsulated. Based upon several years of experience with such claims, management believes that only a small proportion of the claimants has or will ever develop any asbestos-related illness.

        Neither settlement costs in connection with asbestos claims nor annual legal fees to defend these claims have been material in the past. These claims are strongly disputed by the Company and it has been its policy to defend against them aggressively. Many of these cases have been dismissed without any payment whatsoever. Moreover, there is significant insurance coverage with solvent carriers with respect to these claims. However, while costs to defend and settle these claims in the past have not been material, there can be no assurances that this will remain so in the future.

        Management believes that the ultimate resolution of the foregoing contingencies will not have a material effect on the Company's financial statements as a whole.

Antitrust Matters

        Antitrust authorities, including those in the United States and Europe, are investigating possible violations of competition (antitrust) laws by automotive parts suppliers (referred to herein as the "Antitrust Investigations"). The U.S. Department of Justice ("DOJ") initiated an investigation into the Company's Occupant Safety Systems business in June 2011, which was concluded in 2012 when the court approved a plea agreement between one of the Company's German subsidiaries and the DOJ. Also in June 2011, the European Commission initiated an Antitrust Investigation which includes the

24

TRW Automotive Holdings Corp.

Notes to Unaudited Condensed Consolidated Financial Statements (Continued)

17. Contingencies (Continued)

Company, among others, and which is ongoing. While the duration and outcome of the European Commission's investigation is uncertain, a determination that the Company has violated European competition (antitrust) laws could result in significant penalties which could have a material adverse effect on its financial condition, results of operations and cash flows, as well as its reputation. While the Company cannot estimate the ultimate financial impact resulting from the European investigation, it will continue to evaluate developments in this matter on a regular basis and will record an accrual as and when appropriate.

        The Company's policy is to comply with all laws and regulations, including all antitrust and competition laws. The Company is cooperating fully with the competition authorities in the context of their ongoing investigations.

Transaction Litigation

        Following the announcement of the execution of the Merger Agreement on September 15, 2014, the Company, members of our board of directors, ZF, Merger Sub and others have been named as defendants in one or more of the purported class actions filed by purported stockholders of the Company challenging the proposed ZF Merger. The actions seek, among other forms of relief, an order enjoining the ZF Merger, rescinding the Merger Agreement to the extent it has already been implemented, and awarding attorneys' fees and costs. On November 12, 2014, plaintiffs, the Company and other named defendants entered into a memorandum of understanding (the "MOU") agreeing in principle to settle all pending actions in exchange for the Company's agreement to make certain supplemental disclosures, which were filed on the same date in a supplement to TRW's October 20, 2014 definitive proxy statement. Pursuant to the MOU, the parties intend to settle, subject to court approval, certain claims, while the other pending litigation will be dismissed. The Company anticipates the litigation will be resolved and will not interfere with or delay the closing, but until court approval is obtained and the cases are dismissed, some uncertainty remains. The settlement contemplated by the MOU is not, and should not be construed as, an admission of wrongdoing or liability by any defendant.

Item 2.    Management's Discussion and Analysis of Financial Condition and Results of Operations

        The following should be read in conjunction with our Annual Report on Form 10-K for the fiscal year ended December 31, 2014, as amended, filed with the U.S. Securities and Exchange Commission (our "2014 Annual Report") and the other information included herein. Our discussion of trends and conditions supplements and updates such discussion included in our 2014 Annual Report. References in this quarterly report on Form 10-Q (this "Report") to "we," "our," or the "Company" refer to TRW Automotive Holdings Corp., together with its subsidiaries.

EXECUTIVE OVERVIEW

Our Business

        We are among the world's largest and most diversified suppliers of automotive systems, modules and components to global automotive original equipment manufacturers, or OEMs, and related aftermarkets. Our operations primarily encompass the design, manufacture and sale of active and passive safety related products and systems, which often includes the integration of electronics components and systems. We operate our business along four segments: Chassis Systems, Occupant Safety Systems, Electronics and Automotive Components.

        We are primarily a "Tier 1" supplier, with approximately 82% of our end-customer sales in 2014 made to major OEMs. Of our 2014 sales, approximately 42% were in Europe, 33% were in North America, 21% were in Asia, and 4% were in the rest of the world.

Merger Agreement

        On September 15, 2014, we entered into an Agreement and Plan of Merger (the "Merger Agreement") with ZF Friedrichshafen AG, a stock corporation organized and existing under the laws of the Federal Republic of Germany ("ZF"), and MSNA, Inc., a Delaware corporation ("Merger Sub") and a wholly owned subsidiary of ZF held directly by ZF North America, Inc. ("ZNA"), pursuant to which Merger Sub will be merged with and into the Company (the "ZF Merger") with the Company surviving the ZF Merger as an indirect wholly owned subsidiary of ZF. At a special stockholders meeting held on November 19, 2014, the Company's stockholders adopted the Merger Agreement.

        At the effective time of the ZF Merger, each share of our common stock issued and outstanding (other than any shares of our common stock held by ZF, ZNA, Merger Sub or any other wholly owned subsidiary of ZF, treasury shares held by us and shares owned by stockholders who have properly made and not withdrawn a demand for appraisal rights under Delaware law) will be converted into the right to receive $105.60 in cash, without interest (the "Merger Consideration"). In addition, at the effective time of the ZF Merger, (i) all then-outstanding Company stock options, restricted stock units, phantom stock units and performance share units (which will vest at the "maximum level" of performance), whether vested or unvested, will be converted into the right to receive the Merger Consideration, less the exercise price of such awards, if any, and (ii) all then-outstanding Company stock-settled stock appreciation rights, whether vested or unvested, will be converted into the right to receive an amount in cash equal to the excess of the lesser of the Merger Consideration and the "maximum value" of such stock appreciation right over the fair market value per share at the relevant grant date. The consummation of the ZF Merger is subject to the receipt of antitrust approvals in the United States and Mexico and other customary closing conditions. The transaction is expected to close by the end of the second quarter of 2015. If completed, the ZF Merger will result in the Company becoming a wholly owned subsidiary of ZF and our shares will no longer be listed on any public market.

27

Engine Valve Divestiture

        On February 6, 2015, the Company closed the sale of its wholly owned engine valve subsidiaries which represented a material portion of the business to be divested. The closing did not include the transfer of several of the Company's joint ventures involved in the business.

Linkage and Suspension Divestiture

        On April 21, 2015, the Company announced it entered into a definitive agreement to divest its linkage and suspension business for a purchase price of $400 million in cash subject to adjustment in accordance with the agreement as of the closing date. The planned divestiture of the linkage and suspension business, which has annual sales of approximately $550 million, is expected to close by the end of the third quarter of 2015 and is subject to customary closing conditions, including regulatory approvals.

Financial Results

        For the three months ended April 3, 2015:

•

Our net sales were $4.1 billion, which represents a decrease of 7% compared to the prior year period. During the first quarter of 2015, foreign currency exchange negatively impacted sales by $379 million. The increased demand for our active and passive safety products and growth in vehicle production in Europe, North America and China more than offset the impact of lower sales of $105 million related to exiting certain of our brake component and modules businesses in North America and $86 million related to the divestiture of our wholly owned engine valve subsidiaries.

•

Operating income of $534 million was higher compared to $308 million in the prior year period mainly due to the gain on the sale of our wholly owned engine valve subsidiaries, the positive impact of higher volume, as well as higher foreign currency exchange gains and lower restructuring charges.

•

Net earnings attributable to TRW were $366 million compared to $199 million in the prior year period. The increase was primarily due to higher operating income as well as reduced interest expense, partially offset by an increase in income tax expense.

Recent Trends and Conditions

        Our business and operating results are directly affected by the relative strength of the global automotive industry, which tends to be driven by macroeconomic factors such as gross domestic product growth, consumer confidence, fluctuating commodity, currency and fuel prices and regulatory/governmental initiatives. The primary trends and market conditions impacting our business in 2015 include:

General Economic Conditions:

        The global automotive industry remains susceptible to uncertain economic conditions that could adversely impact consumer demand for vehicles. While the U.S. economy remains strong, global economic sentiment continues to be cautious given continued geopolitical uncertainty, and continued volatility within the emerging markets, including the slowing pace of economic growth in China.

        During the first quarter of 2015, while vehicle production levels in North America and China increased, global expectations were tempered by concerns over economic growth. In North America, with the economy showing signs of sustained growth, consumer demand appears to

28

support the current level of vehicle production. In Europe, stimulus measures intended to spur economic growth are continuing with the economy showing early signs of improvement. In China, while stimulus programs were implemented to stabilize the economy and avert a sharper slowdown, the automotive industry continues to expand with automotive suppliers benefiting from increased production levels.

Production Levels:

        Vehicle production levels in North America, Europe and China during the first quarter of 2015 continued on a positive trend.

        Approximately 42% of our sales originated in Europe during 2014. Production levels in Europe were 2% higher in the first quarter of 2015 compared to 2014, primarily due to moderate improvements in the economic environment and customer demand. However, production levels in this region are expected to be flat on a year-over-year basis for the remainder of 2015. We will continue to monitor the geopolitical concerns, primarily in Russia, that could impact this region.

        Approximately 33% of our sales originated in North America during 2014. Production levels in this region increased 2% in the first quarter of 2015 compared to 2014 due to sustained consumer demand supported by, among other things, lower gas prices. The Detroit Three (defined as FCA US LLC, Ford Motor Company, and General Motors Company, combined) lagged production growth for the overall region during the first quarter of 2015. In general, our financial results in North America tend to be more closely correlated to the production by the Detroit Three given our higher sales content to these manufacturers compared to other manufacturers.

        Approximately 25% of our sales originated in regions outside of Europe and North America (primarily China, which comprised approximately 18% of total sales) during 2014. In China, production levels were higher in the first quarter of 2015 compared to 2014 due to increased consumer demand. We expect growth in production levels for the remainder of 2015 in China despite slowing economic growth. In Brazil, production levels were down 15% compared to the prior year period due to economic volatility in the country. While this market represented 4% of our 2014 sales, we are continuing to monitor the market given the challenging conditions experienced.

Changes to Our Debt and Capital Structure

        During the first quarter of 2015, we continued to focus on improving the strength, flexibility, and cost efficiency of our capital structure, resulting in outstanding debt of $1.6 billion and a cash balance of $1.0 billion at April 3, 2015.

        As market conditions warrant, we may, from time to time, repurchase debt securities issued by the Company or its subsidiaries, in privately negotiated or open market transactions, by tender offer, exchange offer, or by other means, or we may optionally redeem such debt securities.

        See "LIQUIDITY AND CAPITAL RESOURCES" below, Part II, Item 2 (c), "Issuer repurchases of equity securities," of this Report and Note 12 to the unaudited condensed consolidated financial statements included in Part I, Item 1 of this Report for further information.

Comparison of the Three Months Ended April 3, 2015 to the Three Months Ended March 28, 2014

Sales decreased by $300 million, or 7%, for the three months ended April 3, 2015 compared to the three months ended March 28, 2014. The decrease in sales was driven by the unfavorable impact of foreign currency exchange of $379 million, as well as lower sales of $191 million as a result of exiting certain of our brake component and modules businesses in North America during the first quarter of 2014 and divesting our wholly owned engine valve subsidiaries during the first quarter of 2015 (together, the "divested businesses"). These items were partially offset by higher production volume, primarily in Europe, North America and China, and increased demand for our active and passive safety products, together totaling $270 million.

        For the three months ended April 3, 2015, the change in TRW sales in North America was less than the increase in vehicle production primarily due to the divested businesses. Excluding the impact of exiting these businesses, sales increased 2% in North America, which was in line with the vehicle production increase in the region. In Europe, TRW sales were also affected by the divestiture of our wholly owned engine valve subsidiaries, as well as foreign currency exchange. Excluding the impact of these factors, sales increased 8%, which was higher than the vehicle production increase in the region, due to a favorable concentration of customers and increased demand for our safety products. In the Rest of World, excluding the impact of the divestiture of our wholly owned engine valve subsidiaries and foreign currency exchange, sales increased 12%, which was more than the industry production increase, due to the mix of platforms and products sold.

Cost of sales decreased by $283 million, or 7%, for the three months ended April 3, 2015 compared to the three months ended March 28, 2014. The decrease was driven primarily by the favorable impact of foreign currency exchange of $352 million, as well as lower cost of sales of $173 million as a result of the divested businesses, partially offset by additional costs associated with increased volume (net of cost reductions) of $242 million.

Gross profit, as a percentage of sales, for the three months ended April 3, 2015 was 11.7% compared to 11.3% for the three months ended March 28, 2014. This margin improvement was primarily driven by the favorable profit impact of additional volume as well as the timing of cost reduction benefits.

        Gross profit decreased by $17 million for the three months ended April 3, 2015 compared to the three months ended March 28, 2014. The decrease was primarily driven by the unfavorable impact of foreign currency exchange of $27 million, as well as a reduction in profit of $18 million as a result of the divested businesses, partially offset by the favorable impact of additional volume (net of cost reductions) of $28 million.

Administrative and selling expenses, as a percentage of sales, were 3.6% for the three months ended April 3, 2015 compared to 3.7% for the three months ended March 28, 2014. The decrease of $16 million was driven by the favorable impact of foreign currency exchange of $13 million, lower costs of $2 million as a result of the divestiture of our wholly owned engine valve subsidiaries, and cost reductions (in excess of non-commodity inflation and other costs) of $1 million.

31

Restructuring charges and asset impairments were $4 million for the three months ended April 3, 2015 compared to $20 million for the three months ended March 28, 2014. This decrease was driven by lower severance and other charges of $4 million and lower asset impairments of $12 million.

Transaction costs were $2 million for the three months ended April 3, 2015. These costs primarily consisted of financial advisory and legal fees related to the ZF Merger and divestiture activity.

Gain on divestiture—net was $186 million for the three months ended April 3, 2015 which relates to the sale of our wholly owned engine valve subsidiaries.

Other (income) expense—net changed by $27 million for the three months ended April 3, 2015 compared to the three months ended March 28, 2014. This increase in income was primarily driven by the favorable impact of foreign currency exchange between periods of $20 million, lower bad debt expense of $1 million, increased gains on the sale of fixed assets of $1 million, as well as lower expenses primarily related to certain legal matters.

Interest expense—net decreased by $8 million for the three months ended April 3, 2015 compared to the three months ended March 28, 2014. The decrease was primarily a result of both lower average debt levels and lower average borrowing rates of our senior notes, both reflecting the maturity in the first quarter 2014 of our 6.375% and 7.00% Senior Notes.

Loss on retirement of debt was $1 million for the three months ended April 3, 2015. During the three months ended April 3, 2015, Exchangeable Senior Note holders exchanged approximately $18 million in principal amount of notes for approximately 623,000 shares of Company stock. In conjunction with the exchanges, we recorded a loss on retirement of debt of $1 million, including the write-off of a portion of related debt issuance costs and debt discount.

Income tax expense for the three months ended April 3, 2015 was $144 million on pre-tax earnings of $521 million compared to an income tax expense of $78 million on pre-tax earnings of $287 million for the three months ended March 28, 2014. For the period ended April 3, 2015, both income tax expense and pre-tax earnings include the impact of the gain on divestiture which did not have a significant impact on the overall effective tax rate for the period.

LIQUIDITY AND CAPITAL RESOURCES

        On an annual basis, our primary source of liquidity is cash flows generated from operations. At various points during the course of a given year, we may be in an operating cash usage position, which is not unusual given the seasonality of our business. We also have available liquidity under our Revolving Credit Facility and other credit facilities, subject to certain conditions. We continuously monitor our working capital position and associated cash requirements and explore opportunities to more effectively manage our inventory and capital spending. Working capital is highly influenced by the timing of cash flows associated with sales and purchases, and therefore can be difficult to manage at times. Although we have historically been successful in managing the timing of our cash flows, future success will depend on the financial position of our customers and suppliers, and on industry conditions.

        We believe that funds generated from operations, cash on hand and available borrowing capacity will be adequate to fund our liquidity requirements. These requirements, which are significant, generally consist of working capital requirements, company-sponsored research and development programs, capital expenditures, contributions for pensions and postretirement benefits other than pensions, and debt service requirements. In addition, we have been using available funds to reduce debt and to repurchase shares of our common stock under our board approved share repurchase programs. Our current financing plans are intended to provide flexibility in worldwide financing activities and permit us to respond to changing conditions in credit markets. However, our ability to continue to fund these items may be affected by general economic, industry specific, financial market, competitive, legislative and regulatory factors, including developments related to the ongoing Antitrust Investigations.

        As of April 3, 2015, the amount of cash and cash equivalents held by foreign subsidiaries was $790 million. If these funds were repatriated to the U.S., we would be required to provide for U.S. federal and state income tax, foreign income tax, and foreign withholding taxes. We have already provided for such taxes on a significant portion of this cash and cash equivalents that are not deemed to be permanently reinvested. However, for the entities that hold the remainder of such cash and cash equivalents, we have not provided for such taxes as it is our intention that those funds are permanently reinvested outside the U.S. and our current plans do not demonstrate a need to repatriate them to fund our U.S. operations.

Cash Flows

        Operating Activities.    Cash used in operating activities for the three months ended April 3, 2015 was $192 million compared to $183 million for the three months ended March 28, 2014. The increase of $9 million between the two periods was primarily related to higher outflows for employee compensation benefits and other liabilities of $64 million, as well as increased restructuring and other severance-related payments of $23 million, partially offset by lower working capital requirements of $81 million.

        Investing Activities.    Cash provided by investing activities for the three months ended April 3, 2015 was $213 million, compared to cash used in investing activities of $105 million for the three months ended March 28, 2014. During the three months ended April 3, 2015 we received net cash proceeds of approximately $313 million in conjunction with the divestiture of our wholly owned engine valve subsidiaries which represented the material portion of the business to be divested. Also, capital expenditures for the three months ended April 3, 2015 were $95 million. These capital expenditures were primarily related to investing in new facilities, upgrading existing products, continuing new product launches, and infrastructure and equipment at our facilities to support our manufacturing and cost reduction efforts. We expect to spend between $650 million and $690 million during 2015 on capital expenditures as we continue to invest in our strategic priorities and growth.

35

        Financing Activities.    Cash provided by financing activities was $28 million for the three months ended April 3, 2015, compared to cash used in financing activities of $631 million for the three months ended March 28, 2014. During the three months ended April 3, 2015, we increased our short-term borrowings by $42 million. Also, during the three months ended April 3, 2015, certain of our subsidiaries paid $13 million of dividends to noncontrolling stockholders.

        Our Eighth Amended and Restated Credit Agreement dated September 28, 2012 (the "Eighth Credit Agreement") provides for senior credit facilities consisting of (i) a revolving credit facility in the amount of $1.4 billion which matures in September 2017, subject to certain conditions (the "Revolving Credit Facility"), and (ii) additional availability which may be used in the future for one or more term loans or additional revolving facilities (together with the Revolving Credit Facility, the "Facilities"). As of April 3, 2015, we had no outstanding borrowings under our Revolving Credit Facility, resulting in $1.4 billion of availability. See "—Senior Credit Facilities" in Note 12 to the unaudited condensed consolidated financial statements included in Part I, Item 1 of this Report for a description of our Revolving Credit Facility. Additionally, if the ZF Merger is consummated, the Company anticipates terminating the Eighth Credit Agreement.

        As of April 3, 2015, our subsidiaries in the United States, European region and Asia Pacific region also had various uncommitted credit facilities with individual banks, of which $525 million, $170 million and $120 million, respectively, was unutilized.

        We may draw down on and use proceeds from any of these credit facilities, including our Revolving Credit Facility, from month to month in conjunction with available cash on hand in order to fund normal working capital needs. As of April 3, 2015, we had short-term borrowings under uncommitted credit facilities totaling $264 million, while during the quarter we had up to $308 million, in aggregate, outstanding under these credit facilities.

        The Eighth Credit Agreement governs our Facilities and contains a number of covenants, including financial covenants, that would impact our ability to borrow on the facility if not met and restrictive covenants that restrict, among other things and subject to certain exceptions, the ability to incur additional indebtedness, repay or repurchase other indebtedness, repurchase capital stock and pay cash dividends on our common stock. As of April 3, 2015, we were in compliance with all of our financial covenants. Such covenants are described in more detail in Note 13 to the consolidated financial statements included in our 2014 Annual Report.

Contractual Obligations and Commitments

        During the three months ended April 3, 2015, there have been no material changes outside the ordinary course of our business to the contractual obligations previously disclosed in "—Contractual Obligations and Commitments" in Part II, Item 7 of our 2014 Annual Report.

Off-Balance Sheet Arrangements

        We do not have material off-balance sheet arrangements. We do not have guarantees related to unconsolidated entities, which have, or are reasonably likely to have, a material current or future effect on our financial position, results of operations or cash flows.

CONTINGENCIES AND ENVIRONMENTAL MATTERS

        The information concerning the ongoing antitrust matters, transaction litigation and other contingencies, including environmental contingencies and the amount currently held in reserve for

environmental matters, contained in Note 17 to our unaudited condensed consolidated financial statements included in Part I, Item 1 of this Report, is incorporated herein by reference.

CRITICAL ACCOUNTING ESTIMATES

        There have been no significant changes in our critical accounting estimates during the three months ended April 3, 2015.

OUTLOOK

        On September 15, 2014, we announced the Merger Agreement with ZF. The closing of the transaction is subject to receipt of antitrust approvals in the United States and Mexico and other customary closing conditions. The transaction is expected to close in the second quarter of 2015. In the interim, we will continue to execute our existing business plan.

        We expect full year 2015 sales to be in the range of $16.2 billion to $16.5 billion. This forecast is based on expected 2015 production levels of 17.4 million units in North America, 20.0 million units in Europe, continued expansion in vehicle production volumes in China, and our expectations for foreign currency exchange rates.

        In general, we expect global production levels to increase in 2015 compared to 2014. In North America, growth is expected to continue moderating as the industry approaches trend demand levels. Production levels for the Detroit Three are expected to lag behind the production levels for the region for the remainder of 2015. In general, our financial results in North America tend to be more closely correlated to the production by the Detroit Three given our higher sales content to these manufacturers compared to other manufacturers. In Europe, production levels are expected to be relatively flat compared to 2014 for the remainder of the year, particularly given the relatively flat economic environment. Further, geopolitical tension may impact the economy and production levels in this region. Growth in China is expected to continue at a moderate pace in 2015. Considering the expected long-term growth within this region, we continue to invest appropriate levels of capital, engineering and infrastructure to underpin our expansion and position us to benefit from these growth opportunities.

        We continue to evaluate our global footprint to ensure that we are properly configured and sized based on changing market conditions and the production plans of our customers. We will continue to assess our cost base primarily in Europe, and in 2015 we intend to continue our restructuring efforts, including plant rationalizations, targeted workforce reductions and adjustments to certain of our fixed costs, to align our operations with the existing environment. As a result, we expect to incur restructuring charges of approximately $60 million in 2015. We believe these efforts are necessary actions in order to preserve our competitiveness and will provide lasting benefit over the long term.

        While we expect net commodity inflation to be immaterial in 2015, we will continue to monitor commodity costs and work with our suppliers and customers to manage changes in such costs as required.

        The Antitrust Investigation by the European Commission is ongoing. While we cannot estimate the ultimate financial impact of the European investigation at this time, we will continue to evaluate developments in this matter on a regular basis and will record an accrual as and when appropriate.

37

        On April 21, 2015, we announced we entered into a definitive agreement to divest our linkage and suspension business. The planned divestiture is expected to close by the end of the third quarter of 2015 and is subject to customary closing conditions, including regulatory approvals.

        Despite the various challenges that the automotive industry faces, we are confident that we will manage through them successfully. We believe that our growth prospects, strong balance sheet, ability to generate cash and our broad array of innovative products provide a firm foundation for continued profitability.

FORWARD-LOOKING STATEMENTS

        This Report includes "forward-looking statements," as that term is defined by the federal securities laws. Forward-looking statements include statements concerning regulatory approvals and the expected timing, completion and effects of the proposed ZF Merger, our outlook for the future, as well as other statements concerning our beliefs, plans, intentions, objectives, goals, strategies, forecasts, future events, future revenue or performance, capital expenditures, financing needs, business trends and other information that is not historical information. When used in this Report, the words "estimates," "expects," "anticipates," "projects," "plans," "intends," "believes," "forecasts," and future or conditional verbs, such as "will," "should," "could" or "may," as well as variations of such words or similar expressions are intended to identify forward-looking statements, although not all forward-looking statements are so designated. All forward-looking statements, including, without limitation, management's examination of historical operating trends and data, are based upon our current expectations and various assumptions, and apply only as of the date of this Report. Our expectations, beliefs and projections are expressed in good faith and we believe there is a reasonable basis for them. However, there can be no assurance that management's expectations, beliefs and projections will be achieved.

        There are a number of risks, uncertainties and other important factors that could cause our actual results to differ materially from those suggested by our forward-looking statements, including those set forth in the Company's 2014 Annual Report under "Item 1A. Risk Factors," including: the occurrence of any event, change or other circumstances that could give rise to the termination of the Merger Agreement, which could have a material adverse effect on us and our stock price; the inability to consummate the proposed ZF Merger or the inability to consummate the ZF Merger in the timeframe or manner currently anticipated, due to the failure to satisfy conditions to completion of the proposed ZF Merger, including that a governmental entity may prohibit, delay or refuse to grant approval for the consummation of the ZF Merger, could have a material adverse effect on us and our stock price; risks related to disruption of management's attention from our ongoing business operations due to the proposed ZF Merger; the effect of the announcement of the proposed ZF Merger on the Company's relationships with its customers, suppliers, joint venture partners and others, as well as our operating results and business generally; strengthening of the U.S. dollar and other foreign currency exchange rate fluctuations impacting our results; economic conditions adversely affecting our business, results or the viability of our supply base; risks associated with non-U.S. operations, including economic and political uncertainty in some regions, adversely affecting our business, results or financial condition; any developments related to antitrust investigations adversely affecting our financial condition, results, cash flows or reputation; pricing pressures from our customers adversely affecting our profitability; global competition adversely affecting our sales, profitability or financial condition; any disruption in our information technology systems adversely impacting our business and operations; any shortage of supplies causing a production disruption for any customers or us; the loss of any of our largest customers or a significant amount of their business, or a significant decline in their production levels, adversely affecting us; our contingent liabilities and tax matters causing us to incur losses or costs; any inability to protect our intellectual property rights adversely affecting our business or our competitive position; costs or adverse effects on our business, reputation or results from governmental regulations;

38

work stoppages or other labor issues at our facilities or those of our customers or others in our supply chain adversely affecting our business, results or financial condition; commodity inflationary pressures adversely affecting our profitability or supply base; any increase in the expense of our pension and other postretirement benefits or the funding requirements of our pension plans reducing our profitability; and other risks and uncertainties set forth in our 2014 Annual Report, in "—Executive Overview" above and in our other filings with the Securities and Exchange Commission.

        All forward-looking statements are expressly qualified in their entirety by such cautionary statements. We do not undertake any obligation to release publicly any update or revision to any of the forward-looking statements.

Item 3.    Quantitative and Qualitative Disclosures about Market Risk

        There have been no material changes to the quantitative and qualitative information about the Company's market risk from those previously disclosed in the Company's 2014 Annual Report.

Item 4.    Controls and Procedures

        Evaluation of Disclosure Controls and Procedures.    Our Chief Executive Officer and Chief Financial Officer, based on their evaluation of the effectiveness of the Company's disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934) as of April 3, 2015, have concluded that the Company's disclosure controls and procedures are effective to ensure that information required to be disclosed by the Company in the reports that it files and submits under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the specified time periods and is accumulated and communicated to the Company's management as appropriate to allow timely decisions regarding required disclosure.

        Changes in Internal Control over Financial Reporting.    There was no change in the Company's internal controls over financial reporting that occurred during the first fiscal quarter of 2015 that has materially affected, or is reasonably likely to materially affect, the Company's internal control over financial reporting.

39

PART II—OTHER INFORMATION

Item 1.    Legal Proceedings

        The information concerning the ongoing antitrust matters, transaction litigation and other legal proceedings involving the Company contained in Note 17 of our unaudited condensed consolidated financial statements included in Part I, Item 1 of this Report is incorporated herein by reference.

Item 1A.    Risk Factors

        There were no material changes in the Company's risk factors from those previously disclosed in the Company's 2014 Annual Report.

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

(c)

Issuer repurchases of equity securities

        The Company has two share repurchase programs in place, consisting of a $2 billion program that extends through December 31, 2016 (the "$2 Billion Program"), and a program that is intended to offset, on an ongoing basis, the dilution created by the Company's stock incentive plan for up to 1.5 million shares in 2015 and each subsequent year (the "Anti-Dilution Program").

        No share repurchases were made in the first quarter of 2015. Approximately $1.1 billion in dollar value of shares may yet be purchased under the terms of the $2 Billion Program and up to 1.5 million shares may be purchased in 2015 under the Anti-Dilution Program. However, pursuant to the terms of its Merger Agreement with ZF, the Company is restricted from repurchasing additional shares of its common stock under its share repurchase programs without ZF's consent.

        Additional information regarding our share repurchase programs can be found in Part II, Item 5 of our 2014 Annual Report.

Basis of Presentation [Abstract]

Earnings (Losses) Per Share

Earnings Per Share. Basic earnings per share are calculated by dividing net earnings by the weighted average shares outstanding during the period. Diluted earnings per share reflect the weighted average impact of all potentially dilutive securities from the date of issuance, including stock options, RSUs,SSARs and Performance Units. Further, if the inclusion of shares potentially issuable for the Company's 3.50% exchangeable senior unsecured notes (see Note 12) is more dilutive than the inclusion of the interest expense for those exchangeable notes, the Company utilizes the “if-converted” method to calculate diluted earnings per share. Under the if-converted method, the Company adjusts net earnings to add back interest expense and amortization of the discount recognized on the exchangeable notes and includes the number of shares potentially issuable related to the exchangeable notes in the weighted average shares outstanding.

If the average market price of the Company's common stock exceeds the exercise price of stock options outstanding or the fair value on the date of grant of the SSARs, the treasury stock method is used to determine the incremental number of shares to be included in the diluted earnings per share computation.

Warranties

Warranties. Product warranty liabilities are recorded based upon management estimates including such factors as the written agreement with the customer, the length of the warranty period, the historical performance of the product and likely changes in performance of newer products and the mix and volume of products sold. Product warranty liabilities are reviewed on a regular basis and adjusted to reflect actual experience.

Recently Issued Accounting Pronouncements

Recently Adopted or Issued Accounting Pronouncements. In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (''ASU'') No. 2014-09, ''Revenue from Contracts with Customers (Topic 606),'' which provides a single revenue recognition model intended to improve comparability over a range of industries, companies and geographical boundaries and to enhance disclosures. The standard is effective retrospectively for fiscal years (and interim reporting periods within those years) beginning after December 15, 2016. Early adoption is not permitted. The Company continues to assess the potential impact on its operations and financial statements.

In April 2015, the FASB issued ASU No. 2015-03, ''Simplifying the Presentation of Debt Issuance Costs (Subtopic 835-30),'' which requires debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The standard is effective retrospectively for fiscal years beginning after December 15, 2015, and interim periods within fiscal years beginning after December 15, 2016. Early adoption is permitted. When adopted, the implementation of this ASU will not have a material impact on the Company's consolidated financial statements.

3. Basis of Presentation

These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2014, as amended, filed with the U.S. Securities and Exchange Commission (“SEC”).

These unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the SEC for interim financial information. Accordingly, they do not include all of the information and footnotes required by United States generally accepted accounting principles (“GAAP”) for complete financial statements. These financial statements include all adjustments (consisting primarily of normal, recurring adjustments) considered necessary for a fair presentation of the financial position, results of operations and cash flows of the Company. Operating results for the three months ended April 3, 2015 are not necessarily indicative of results that may be expected for the year ending December 31, 2015.

The Company follows a fiscal calendar that ends on December 31. However, each fiscal quarter has three periods consisting of one five week period and two four week periods. Each quarterly period ends on a Friday, with the possible exception of the final quarter of the year, which always ends on December 31.

Earnings Per Share. Basic earnings per share are calculated by dividing net earnings by the weighted average shares outstanding during the period. Diluted earnings per share reflect the weighted average impact of all potentially dilutive securities from the date of issuance, including stock options, RSUs,SSARs and Performance Units. Further, if the inclusion of shares potentially issuable for the Company's 3.50% exchangeable senior unsecured notes (see Note 12) is more dilutive than the inclusion of the interest expense for those exchangeable notes, the Company utilizes the “if-converted” method to calculate diluted earnings per share. Under the if-converted method, the Company adjusts net earnings to add back interest expense and amortization of the discount recognized on the exchangeable notes and includes the number of shares potentially issuable related to the exchangeable notes in the weighted average shares outstanding.

If the average market price of the Company's common stock exceeds the exercise price of stock options outstanding or the fair value on the date of grant of the SSARs, the treasury stock method is used to determine the incremental number of shares to be included in the diluted earnings per share computation.

For the three months ended April 3, 2015, no securities were anti-dilutive to earnings per share. For the three months ended March 28, 2014, approximately1.0millionsecuritieswere excluded from the calculation of diluted earnings per share because the inclusion of such securities in the calculation would have been anti-dilutive.

Merger [Abstract]

Merger [Text Block]

2. Merger

On September 15, 2014, the Company entered into an Agreement and Plan of Merger (the “Merger Agreement”) with ZF Friedrichshafen AG, a stock corporation organized and existing under the laws of the Federal Republic of Germany (“ZF”), and MSNA, Inc., a Delaware corporation (“Merger Sub”) and a wholly owned subsidiary of ZF held directly by ZF North America, Inc. (“ZNA”), pursuant to which Merger Sub will be merged with and into the Company (the “ZF Merger”) with the Company surviving the ZF Merger as an indirect wholly owned subsidiary of ZF. At a special stockholders meeting held on November 19, 2014, the Company's stockholders adopted the Merger Agreement.

At the effective time of the ZF Merger, each share of the Company's common stock issued and outstanding (other than any shares of Company common stock held by ZF, ZNA, Merger Sub or any other wholly owned subsidiary of ZF, treasury shares held by the Company and shares owned by stockholders who have properly made and not withdrawn a demand for appraisal rights under Delaware law) will be converted into the right to receive $105.60 in cash, without interest (the “Merger Consideration”). In addition, at the effective time of the ZF Merger, (i) all then-outstanding Company stock options, restricted stock units (“RSUs”), phantom stock units (“PSUs”) and performance share units (“Performance Units,” which will vest at the “maximum level” of performance), whether vested or unvested, will be converted into the right to receive the Merger Consideration, less the exercise price of such awards, if any, and (ii) all then-outstanding Company stock-settled stock appreciation rights (“SSARs”), whether vested or unvested, will be converted into the right to receive an amount in cash equal to the excess of the lesser of the Merger Consideration and the “maximum value” of such stock appreciation right over the fair market value per share at the relevant grant date. The consummation of the ZF Merger is subject to the receipt of antitrust approvals in the United States and Mexico and other customary closing conditions. The transaction is expected to close by the end of the second quarter of 2015. If completed, the ZF Merger will result in the Company becoming a wholly owned subsidiary of ZF and its shares will no longer be listed on any public market.

16. Share-Based Compensation and Cash Incentive Awards

Equity Awards

As of April 3, 2015, the Company had 3,390,506 shares of Common Stock available for issuance under the TRW Automotive Holdings Corp 2012 Stock Incentive Plan (the “2012 Plan”). In addition, under the 2012 Plan and the Company's 2003 Stock Incentive Plan (as amended, the “2003 Plan” and, together with the 2012 Plan, the “Plan”),195,496 stock options,1,958,805 SSARs,318,889nonvestedRSUs,3,113nonvestedPSUs and nonvested Performance Units under which up to 70,425 shares may be issued (based on maximum performance thereunder) were outstanding as of April 3, 2015. Under the terms of the respective grants, all of the SSARs andstock options have an 8-year term and vest ratably over three years, substantially all of the RSUsvest ratably over three years,all of the PSUs vest ratably over three years and Performance Units cliff vest after their three-year performance period.As a result of changes to retirement provisions in the equity award agreements beginning in 2013,the Company applies a non-substantive vesting period approach for certain of the awards granted in 2014 and 2013 whereby expense is accelerated for those employees who receive awards and are eligible to retire prior to the award vesting.

Share-based compensation expense recognized for the Plan was as follows:

Potential Impactof the ZF Merger on Equity Awards

If consummated, at the effective time of the ZF Merger, (i) all then-outstanding Company stock options, RSUs, PSUs and Performance Units (which will vest at the “maximum level” of performance), whether vested or unvested, will be converted into the right to receive the Merger Consideration, less the exercise price of such awards, if any, and (ii) all then-outstanding Company SSARs, whether vested or unvested, will be converted into the right to receive an amount in cash equal to the excess of the lesser of the Merger Consideration and the “maximum value” of such SSAR over the fair market value per share at the relevant grant date.

Cash Incentive Awards

On February 12, 2015, the Company issued cash incentive awards to executive officers and certain employees of the Company. Each award is divided into three tranches of equal value with a tranche vesting on each of the first, second and third anniversaries of the grant date. The aggregate value of the awards is approximately $33 million. The Company applies a non-substantive vesting period approach whereby expense is accelerated for those employees who receive awards and are eligible to retire prior to the award vesting. For the three months ended April 3, 2015, the Company recognized approximately $2 million of compensation expense and corresponding liability related to these awards.

Fair Value Measurements and Financial Instruments

Fair Value Disclosures [Abstract]

Fair Value Measurements and Financial Instruments [Text Block]

11. Fair Value Measurements and Financial Instruments

The inputs to valuation techniques used to measure fair value are prioritized into a three-level hierarchy. This hierarchy gives the highest priority to quoted prices in active markets for identical assets and liabilities and lowest priority to unobservable inputs, as follows:

       Level 1. Inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company can access at the measurement date.

       Level 2.Inputs are other than quoted prices that are observable for the asset or liability, either directly or indirectly.

       Level 3. Unobservable inputs are supported by little or no market activity. The unobservable inputs represent the Company's best assumptions of how market participants would price the assets or liabilities.

Items Measured at Fair Value on a Recurring Basis

The fair value measurements for assets and liabilities recognized in the Company's condensed consolidated balance sheets are as follows:

	As of
	April 3, 2015		December 31, 2014		Measurement Approach
	(Dollars in millions)
Foreign currency exchange contracts — current assets	$	38	$	7	Level 2
Foreign currency exchange contracts — noncurrent assets		23		2	Level 2
Foreign currency exchange contracts — current liability		14		13	Level 2
Foreign currency exchange contracts — noncurrent liability		14		13	Level 2

The Company's foreign currency exchange contracts are recorded at fair value derived principally from or corroborated by observable market data under the market approach. Inputs include quoted prices for similar assets and liabilities (risk adjusted), and market-corroborated inputs, such as market comparables, interest rates, yield curves and other items that allow value to be determined. The Company uses quoted currency forward rates to calculate forward values, and then discounts the forward values. In addition, the Company's calculation of the fair value of its foreign currency option contracts uses quoted currency volatilities.

The discount rates for all derivative contracts are based on quoted bank deposit rates. For contracts which, when aggregated by counterparty, are in a liability position, the rates are adjusted by the credit spread which market participants would apply if buying these contracts from the Company's counterparties.

There were no changes in the Company's valuation techniques during the three months endedApril 3, 2015.

Items Measured at Fair Value on a Nonrecurring Basis

In addition to items that are measured at fair value on a recurring basis,we also have assets that may be measured at fair value on a nonrecurring basis. These assets include long-lived assets, intangible assets and investments in affiliates, which may be written down to fair value as a result of impairment.

The Company has determined that the fair value measurements related to each of these assets rely primarily on Company-specific inputs and the Company's assumptions about the use of the assets, as observable inputs are not available. As such, the Company has determined that each of these fair value measurements reside within Level 3 of the fair value hierarchy. To determine the fair value of long-lived assets, the Company utilizes the projected cash flows expected to be generated by the long-lived assets, then discounts the future cash flows over the useful life of the long-lived assets by using a risk-adjusted rate for the Company. The Company records asset impairments associated with its determination of the fair value of its long-lived assets that exhibited indicators of impairment (see Note 13).

Financial Instruments Not Carried at Fair Value

       The carrying value and estimated fair value of financial instruments that are not carried on the Company's balance sheet at fair value are as follows:

	As of
	April 3, 2015				December 31, 2014
		Carrying	Fair		Carrying			Fair	Measurement
		Value	Value		Value			Value	Approach
	(Dollars in millions)
Short-term debt, fixed and floating rate	$	264	$	264	$	222	$	222	Level 2
Fixed rate long-term debt	$	1,318	$	1,382	$	1,326	$	1,389	Level 2
Fixed rate exchangeable notes	$	12	$	45	$	30	$	109	Level 2

The carrying value of short-term debt approximates fair value because of the short term nature of these instruments. The fair value of long term debt was determined primarily from quoted market prices, as provided by participants in the secondary marketplace. For long-term debt without a quoted market price, the Company estimates the fair value using discounted cash flow models with market based borrowing rates for similar types of arrangements.

Derivative Instruments and Hedging Activities

The Company is exposed to fluctuations in foreign currency exchange rates, interest rates and commodity prices. The Company enters into derivative instruments primarily to hedge portions of its forecasted foreign currency denominated cash flows and designates these derivative instruments as cash flow hedges in order to qualify for hedge accounting. Certain foreign exchange contracts that do not qualify for hedge accounting are entered into to hedge recognized foreign currency transactions. All gains or losses on derivative instruments which are not designated for hedge accounting treatment or do not qualify for hedge accounting, or result from hedge ineffectiveness, are reported in earnings immediately.

In addition, the Company is exposed to credit loss in the event of nonperformance by the counterparty to the derivative financial instruments. The Company attempts to limit this exposure by entering into agreements directly with a number of major financial institutions that meet the Company's credit standards and that are expected to fully satisfy their obligations under the contracts, and by monitoring the Company's credit exposure to each counterparty in light of its current credit quality.

As of April 3, 2015, the Company had a notional value of $2.7 billion in foreign exchange contracts outstanding. These foreign exchange contracts mature at various dates through March 2018.

Cash Flow Hedges. For any derivative instrument that is designated and qualifies as a cash flow hedge, the effective portion of the gain or loss on the derivative is reported as a component of Other Comprehensive Income (“OCI”), and is subsequently reclassified into earnings in the period which the hedged transaction affects earnings. The earnings impact is reported either in sales, cost of sales, or other (income) expense ‒ net, to match the underlying transaction. Gains and losses on the derivative representing either hedge ineffectiveness or hedge components excluded from the assessment of effectiveness are recognized in other (income) expense‒net. Such amounts were immaterial for the three months ended April 3, 2015 and March 28, 2014.

The effective portion of gains and losses on derivatives designated as cash flow hedges which were related to foreign currency exchange contracts and recognized in OCI was again of $50 million for the three months ended April 3, 2015, compared to a loss of $3 million for the three months ended March 28, 2014.

The effective portion of gains and losses on cash flow hedges reclassified from OCI into the statement of earnings for the three months ended April 3, 2015 was a gain of $3 million, and was included in various line items on the statement of earnings, compared to a loss of $3 million for the three months ended March 28, 2014.

Gains and losses reclassified into earnings include the discontinuance of cash flow hedges, which were immaterial for each of the three months ended April 3, 2015and March 28, 2014. Approximately $19 million of gains, net of tax, which are included in OCI, are expected to be reclassified into earnings in the next twelve months.

Undesignated Derivatives. For the three months ended April 3, 2015, the Company recognized gains of $29 million in other (income) expense ‒ net, for derivative instruments not designated as hedging instruments. For the three months ended March 28, 2014, the Company recognized losses of a de minimis amountin other (income) expense ‒net, for derivative instruments not designated as hedging instruments.

Credit-Risk-Related Contingent Features. The Company has entered into International Swaps and Derivatives Association (“ISDA”) agreements with each of its significant derivative counterparties. These agreements provide bilateral netting and offsetting of accounts that are in a liability position with those that are in an asset position. These agreements do not require the Company to maintain a minimum credit rating in order to be in compliance with the terms of the agreements and do not contain any margin call provisions or collateral requirements that could be triggered by derivative instruments in a net liability position. These agreements provide for an additional termination event if theCompany's Eighth Amended and Restated Credit Agreement dated September 28, 2012 (the “Eighth Credit Agreement”) is terminated or a change of control occurs under the Eighth Credit Agreement. The ZF Merger, if consummated, is expected to cause an additional termination event under these agreements. The occurrence of an additional termination event would allow the Company and each of the counterparties to request cancellation and settlement of the mark-to-market position for any outstanding derivative contracts, regardless of the maturity date of the contract.

Senior Notes

4.45% Senior Notes.In November 2013, the Company issued $400 million in aggregate principal amount of 4.45% senior unsecured notes due 2023 in a private placement. Interest is payable semi-annually on December 1 and June 1 of each year.

4.50% Senior Notes.In February 2013, the Company issued $400 million in aggregate principal amount of 4.50% senior unsecured notes due 2021 in a private placement. Interest is payable semi-annually on March 1 and September 1 of each year.

7.25% Senior Notes.In March 2007, the Company issued $600 million in aggregate principal amount of 7.25% senior unsecured notes due 2017 in a private placement. Interest is payable semi-annually on March 15 and September 15 of each year.

Exchangeable Senior Notes

In November 2009, the Company issued approximately $259 million in aggregate principal amount of 3.50% exchangeable senior unsecured notes due December 1, 2015 (the “Exchangeable Senior Notes”) in a private placement. By their terms, prior to September 1, 2015, the notes were exchangeable only upon specified events or conditions being met and, thereafter, at any time. The initial exchange rate was 33.8392 shares of the Company's common stock per $1,000 principal amount of notes.

In the first quarter of 2015, in accordance with the Exchangeable Senior Note indenture, $18 million in principal amount of Exchangeable Senior Notes were exchanged for approximately623,000 shares of common stock. A $1 million loss on retirement of debt was recorded relating to the write-off of a portion of debt issue costs and the debt discount, as well as a reduction of $46 million to paid-in-capital relating to the repurchase of the conversion feature of the Exchangeable Senior Notes. The repurchased notes were retired upon settlement.

During March 2015, in accordance with provisions in the Exchangeable Senior Notes indenture, the Company provided to note holders a notice that it would optionally redeem all outstanding notes at par value, plus accrued interest, on April 9, 2015. Subsequent to quarter end, Exchangeable Senior Notes of approximately $13 million in principal amount, excluding $1 million of discount,were exchanged for 437,000 shares of common stock. On April 9, 2015, the Company redeemed the remaining notes outstanding of approximately $23,000at par value, plus accrued interest.

Senior Credit Facilities

The Eighth Credit Agreementprovides for senior credit facilities consisting of (i) a revolving credit facility in the amount of $1.4 billion which matures in September 2017, subject to certain liquidity conditions being met in October 2016 (the “Revolving Credit Facility”), and (ii) additional availability which may be used in the future for one or more term loans or additional revolving facilities (together with the Revolving Credit Facility, the “Facilities”). All of the Facilities were undrawn as of April 3, 2015.

The commitment fee and the applicable margin for borrowing on the Revolving Credit Facility are subject to a ratings-based grid. The applicable margin in effect as of April 3, 2015was0.25% with respect to base rate borrowings,1.25% with respect to eurocurrency borrowings, and the commitment fee on the undrawn amounts under the Revolving Credit Facility was 0.25%.

Other Borrowings

The Company has borrowings under uncommitted credit agreements in several of the countries in which it operates. The borrowings are from various individual banks at quoted market interest rates. As of April 3, 2015, the Company had short-term borrowings under uncommitted credit facilities totaling $264 million.

Debt Repurchases

As market conditions warrant, the Company may from time to time repurchase debt securitiesissued by the Company or its subsidiaries, in privately negotiated or open market transactions, by tender offer, exchange offer, or by other means, or the Company may optionally redeem such debt securities.

Debt Covenants Potentially Impacted by the ZF Merger

The ZF Merger, if consummated, is expected to cause a change of control triggering event as defined in the Company's respective Senior Note indentures. In general, upon the occurrence of a change of control triggering event under the Senior Note indentures, the Company is required to offer to repurchase the Senior Notes, for a certain period of time, at a price of 101% of par, plus accrued and unpaid interest. Additionally, if the ZF Merger is consummated, the Company anticipates terminating the Eighth Credit Agreement.

6. Investment in Joint Venture Affiliate

In 2014, the Company entered into a joint venture of which the Company owns a 30% share. This joint venture will construct and operate a casting foundry in order to supply castings to the Company's North American Braking operations through a long-term supply arrangement, which is deemed to contain an embedded lease arrangement.

During the three months ended April 3, 2015, the Company made equity and working capital contributions of approximately $5 million. Including contributions made in 2014, the Company's total cash investment is approximately $21 million. For accounting purposes only, the Company is deemed to be the owner of the casting foundry during the construction period. Therefore, as of April 3, 2015,the Company recorded $58 million as construction-in-process and $41 million in long-term liabilities. The liability does not represent a legal obligation to pay cash.

Contingencies [Abstract]

Contingencies

17. Contingencies

Various claims, lawsuits and administrative proceedings are pending or threatened against the Company or its subsidiaries, covering a wide range of matters that arise in the ordinary course of the Company's business activities with respect to commercial, patent, product liability, environmental and occupational safety and health law matters. In addition, the Company and its subsidiaries are conducting a number of environmental investigations and remedial actions at current and former locations of certain of the Company's subsidiaries. Along with other companies, certain subsidiaries of the Company have been named potentially responsible parties for certain waste management sites. Each of these matters is subject to various uncertainties, and some of these matters may be resolved unfavorably with respect to the Company or the relevant subsidiary. A reserve estimate for each environmental matter is established using standard engineering cost estimating techniques on an undiscounted basis. In the determination of such costs, consideration is given to the professional judgment of Company environmental engineers, in consultation with outside environmental specialists, when necessary. At multi-party sites, the reserve estimate also reflects the expected allocation of total project costs among the various potentially responsible parties.

As of April 3, 2015, the Company had reserves for environmental matters of $70 million. In addition, the Company has established a receivable for a portion of this environmental liability as a result of its right to indemnification for 50% of any environmental liabilities associated with the operation or ownership of the Company's automotive business existing at or prior to March 2003. The Company believes any liability, in excess of amounts accrued in its financial statements, that may result from the resolution of environmental matters for which sufficient information is available to support these cost estimates, will not have a material adverse effect on the Company's financial position, results of operations or cash flows.

The Company faces an inherent business risk of exposure to product liability, recall and warranty claims in the event that its products actually or allegedly fail to perform as expected or the use of its products results, or is alleged to result, in bodily injury and/or property damage. Accordingly, the Company could experience material warranty, recall or product liability losses in the future. For further information, including quantification of the Company's product warranty liability, see the description of “Warranties” in Note 3.

While certain of the Company's subsidiaries have been subject in recent years to asbestos-related claims, management believes that such claims will not have a material adverse effect on the Company's financial statements. In general, these claims seek damages for illnesses alleged to have resulted from exposure to asbestos used in certain components sold in the past by the Company's subsidiaries. Management believes that the majority of the claimants were vehicle mechanics. The vast majority of these claims name as defendants numerous manufacturers and suppliers of a variety of products allegedly containing asbestos. Management believes that, to the extent any of the products sold by the Company's subsidiaries and at issue in these cases contained asbestos, the asbestos was encapsulated. Based upon several years of experience with such claims, management believes that only a small proportion of the claimants has or will ever develop any asbestos-related illness.

Neither settlement costs in connection with asbestos claims nor annual legal fees to defend these claims have been material in the past. These claims are strongly disputed by the Company and it has been its policy to defend against them aggressively. Many of these cases have been dismissed without any payment whatsoever. Moreover, there is significant insurance coverage with solvent carriers with respect to these claims. However, while costs to defend and settle these claims in the past have not been material, there can be no assurances that this will remain so in the future.

Management believes that the ultimate resolution of the foregoing contingencies will not have a material effect on the Company's financial statements as a whole.

Antitrust Matters

Antitrust authorities, including those in the United States and Europe, are investigating possible violations of competition (antitrust) laws by automotive parts suppliers (referred to herein as the “Antitrust Investigations”). The U.S. Department of Justice (“DOJ”) initiated an investigation into the Company's Occupant Safety Systems business in June 2011, which was concluded in 2012 when the court approved a plea agreement between one of the Company's German subsidiaries and the DOJ. Also in June 2011, the European Commission initiated an Antitrust Investigation which includes the Company, among others, and which is ongoing. While the duration and outcome of the European Commission's investigation is uncertain, a determination that the Company has violated European competition (antitrust) laws could result in significant penalties which could have a material adverse effect on its financial condition, results of operations and cash flows, as well as its reputation. While the Company cannot estimate the ultimate financial impact resulting from the European investigation, it will continue to evaluate developments in this matter on a regular basis and will record an accrual as and when appropriate.

The Company's policy is to comply with all laws and regulations, including all antitrust and competition laws. The Company is cooperating fully with the competition authorities in the context of their ongoing investigations.

Transaction Litigation

Following the announcement of the execution of the Merger Agreement on September 15, 2014, the Company, members of our board of directors, ZF, Merger Sub and others have been named as defendants in one or more of the purported class actions filed by purported stockholders of the Company challenging the proposed ZF Merger. The actions seek, among other forms of relief, an order enjoining the ZF Merger, rescinding the Merger Agreement to the extent it has already been implemented, and awarding attorneys' fees and costs. On November 12, 2014, plaintiffs, the Company and other named defendants entered into a memorandum of understanding (the “MOU”) agreeing in principle to settle all pending actions in exchange for the Company's agreement to make certain supplemental disclosures, which were filed on the same date in a supplement to TRW's October 20, 2014 definitive proxy statement.  Pursuant to the MOU, the parties intend to settle, subject to court approval, certain claims, while the other pending litigation will be dismissed.  The Company anticipates the litigation will be resolved and will not interfere with or delay the closing, but until court approval is obtained and the cases are dismissed, some uncertainty remains.  The settlement contemplated by the MOU is not, and should not be construed as, an admission of wrongdoing or liability by any defendant.

Income Taxes

9. Income Taxes

The Company adjusts its effective tax rate each quarter to be consistent with the estimated annual effective tax rate and records the tax impact of unusual or infrequently occurring items, including changes in judgment about valuation allowances and effects of changes in tax laws or rates, in the interim period in which they occur.

Income tax expense for the three months ended April 3, 2015 was $144 million on pre-tax earnings of $521 million. Income tax expense for the three months ended March 28, 2014 was $78 million on pre-tax earnings of $287 million. For the period ended April 3, 2015, both income tax expense and pre-tax earnings include the impact of the gain on divestiture, which did not have a significant impact on the overall effective tax rate for the period.For the periods ended April 3, 2015 and March 28, 2014, the income tax rate varies from the United States statutory income tax rate primarily due to favorable foreign tax rates, holidays, and credits, as well as the effect of the gain on divestiture.

The Company operates in multiple jurisdictions throughout the world and the income tax returns of several subsidiaries in various tax jurisdictions are currently under examination. Although it is not possible to predict the timing of the conclusions of all ongoing tax audits with accuracy, it is possible that some or all of these examinations will conclude within the next 12 months. It is also reasonably possible that certain statutes of limitations may expire relating to various foreign jurisdictions within the next 12 months. As such, it is possible that a change in the Company's gross unrecognized tax benefits may occur; however, it is not possible to reasonably estimate the potential change in gross unrecognized tax benefits.

Capital Stock [Abstract]

Capital Stock

15. Capital Stock

The Company's authorized capital stock consists of (i) 500 million shares of common stock, par value $.01 per share (the “Common Stock”), of which 115,487,709 shares were issued and outstanding as of April 3, 2015, net of 4,668 shares of treasury stock withheld at cost to satisfy tax obligations for a specific grant under the Company's stock-based compensation plan; and (ii) 250 million shares of preferred stock, par value $.01 per share, including 500,000 shares of Series A junior participating preferred stock, of which no shares are currently issued or outstanding.

From time to time, capital stock is issued in conjunction with the exercise of stock options and stock-settled stock appreciation rights and the vesting of restricted stock units issued as part of the Company's stock incentive plan (see Note 16).

Share Repurchase Programs. The Company has two share repurchase programs in place, consisting of a $2 billion program that extends through December 31, 2016 (the “$2 Billion Program”), and a program that is intended to offset, on an ongoing basis, the dilution created by the Company's stock incentive plan for up to 1.5 million shares in 2015 and each subsequent year (the “Anti-Dilution Program”). The Anti-Dilution program does not have an expiration date. The Company is not obligated to repurchase any shares under either program.

Pursuant to the terms of the Merger Agreement with ZF, the Company is restricted from repurchasing additional shares of its common stock under the share repurchase programs without ZF's consent.

4. Divestiture and Assets Held-For-Sale

Divestiture

During the three months endedApril 3, 2015, the Company closed the sale of its whollyowned engine valve subsidiaries which represented the material portion of the business to be divested. The closing did not include the transfer of several of the Company's joint ventures involved in the business which remain held-for-sale as of April 3, 2015. The engine valve business is reported within the Automotive Components segment (see Note 18). The Company received net cash proceedsof approximately $313 million and recognized a gain on sale of $186 million for this divestiture.

Assets Held-For-Sale

In response to the European Commission's conditional antitrust approval of the ZF Merger, the Companycommenced the process ofmarketing its linkage and suspension business to potential qualified buyers. The linkage and suspension business is reported within the Chassis Systems segment (see Note 18).This business met the definition of held-for-sale, and as such, the assets and liabilities associated with the transaction are separately classified as held-for-sale in the condensed consolidated balance sheet as of April 3, 2015 and depreciation of long-lived assets has ceased. The divestiture did not meet the criteria for presentation as a discontinued operation.

Subsequent to the end of the Company's first quarter, on April 21, 2015, the Company entered into a definitive agreement to divest its linkage and suspension business for a purchase price of $400 million in cash which is subject to adjustment in accordance with the agreement as of the closing date. The planned divestiture of the linkage and suspension business is expected to close by the end of the third quarter of 2015 and is subject to customary closing conditions, including regulatory approvals.

The major classes of assets and liabilities held-for-sale, which includes the Company's linkage and suspension business and the engine valve joint ventures, were as follows: 

		As of
		April 3, 2015
		(Dollars in millions)
