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. Active safety related products principally refer to vehicle dynamic controls (primarily braking and steering), and passive safety related products principally refer to occupant restraints (primarily airbags and seat belts) and safety electronics (electronic control units and crash and occupant weight sensors). The Company is primarily a "Tier 1" supplier (a supplier that sells to OEMs). In 2012, approximately 86% of the Company's end-customer sales were to major OEMs.

2. 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, 2012, filed with the U.S. Securities and Exchange Commission ("SEC") on February 15, 2013.

        In the first quarter of 2013, the Company began to manage and report certain components that were previously within its Electronics segment as part of its Chassis Systems segment. As a result, these components were reclassified and are now included within the Company's Chassis Systems segment. As such, the Company has made appropriate adjustments to its segment-related disclosures for 2013, as well as prior periods.

        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 and six months ended June 28, 2013 are not necessarily indicative of results that may be expected for the year ending December 31, 2013.

        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, restricted stock units ("RSUs") and stock-settled stock appreciation rights ("SSARs"). Further, if the inclusion of shares potentially issuable for the Company's 3.50% exchangeable senior unsecured notes (see Note 10) 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

2. Basis of Presentation (Continued)

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:

	Three Months Ended				Six Months Ended
	June 28, 2013		June 29, 2012		June 28, 2013		June 29, 2012

Diluted earnings per share	$	1.99	$	1.71	$	3.28	$	3.30

        For both the three and six months ended June 28, 2013, approximately 1.6 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.

        For the three and six months ended June 29, 2012, approximately 2.9 million and 2.4 million securities, respectively, were excluded from the calculation of diluted earnings per share because the inclusion of such securities in the calculation would have been anti-dilutive.

Income tax expense for the six months ended June 28, 2013 includes a tax benefit of $12 million relating to the enactment of the American Taxpayer Relief Act of 2012 (as discussed below), a net tax benefit of $4 million relating to the resolution of various tax matters in foreign jurisdictions, and a net tax expense relating to other discrete tax items, resulting in a net tax benefit of $8 million for the period. For the period ended June 28, 2013, 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 enactment of the American Taxpayer Relief Act of 2012.

        The Company reviews the likelihood that it will realize the benefit of its deferred tax assets and, therefore, the need for valuation allowances on a quarterly basis, or more frequently if events indicate that a review is required. In determining the requirement for a valuation allowance, the historical and projected financial results of the legal entity or consolidated group recording the net deferred tax asset is considered, along with all other available positive and negative evidence. The Company utilizes a rolling twelve quarters of pre-tax results adjusted for significant permanent book to tax differences as a measure of cumulative results in recent years. The factors considered by management in its determination of the probability of the realization of the deferred tax assets include but are not limited to: recent historical financial results, historical taxable income, projected future taxable income, the expected timing of the reversals of existing temporary differences and tax planning strategies. If, based upon the weight of available evidence, it is more likely than not the deferred tax assets will not be

realized, a valuation allowance is recorded. If operating results improve or deteriorate on a sustained basis, the Company's conclusions regarding the need for a valuation allowance could change, resulting in either the reversal or initial recognition of a valuation allowance in the future, which could have a significant impact on income tax expense in the period recognized and subsequent periods. The recent U.S. economic recovery and improvement in the North American automotive market, along with improved Company performance, have all had a favorable impact on U.S. operating results. If such performance continues, the Company may be in a position, in future periods, to utilize certain historical foreign tax credits in excess of previous expectations, which could have a significant favorable impact on income tax expense in the period recognized.

        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 statute 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 effect this may have upon the gross unrecognized tax benefits.

        On January 2, 2013, the American Taxpayer Relief Act of 2012 was enacted, which retroactively reinstated and extended various tax provisions applicable to the Company, including the research and development tax credit and the look through rules for controlled foreign corporations. The effect of a tax law change, including any retroactive effect, is accounted for in the period of enactment. As a result, the Company recorded a discrete tax benefit during the first quarter related to this legislation.

        On July 17, 2013, the United Kingdom—Finance Bill of 2013 received Royal Assent, thereby becoming law as the Finance Act 2013 (the "Act"). The Act provides for a reduction to the corporate income tax rate from 23% to 21% effective April 1, 2014, with a further reduction to 20% effective April 1, 2015. The impact of this legislation will be recorded as a discrete item during the third quarter, the period of enactment, and will result in a tax benefit of approximately $20 million.

8. Fair Value Measurements

        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.    The Company utilizes the market approach to determine the fair value of its assets and liabilities under Level 1 of the fair value hierarchy. The market approach pertains to transactions in active markets involving identical or comparable assets or liabilities.

        Level 2.     The fair values determined through Level 2 of the fair value hierarchy are 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.

        Level 3.     The Company utilizes the income approach or the cost approach, as appropriate, to determine the fair value of its assets and liabilities under Level 3 of the fair value hierarchy. The fair value is derived principally from unobservable inputs from the Company's own assumptions about market risk, developed based on the best information available, subject to cost-benefit analysis, and may include the Company's own data. When there are pension related assets with fair value determined through Level 3, fair value is derived principally from unobservable inputs provided by the trustee. When there are no observable comparables, inputs used to determine value are derived from Company-specific inputs, such as projected financial data and the Company's own views about the assumptions that market participants would use.

8. Fair Value Measurements (Continued)

Items Measured at Fair Value on a Recurring Basis

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

	As of
	June 28, 2013					December 31, 2012
	Carrying Value		Fair Value		Measurement Approach	Carrying Value		Fair Value
	(Dollars in millions)
Foreign currency exchange contracts—current assets	$	4	$	4	Level 2	$	16	$	16
Foreign currency exchange contracts—noncurrent assets		—		—	Level 2		9		9
Short-term debt, fixed and floating rate		87		87	Level 2		67		67
Fixed rate long-term debt		1,769		2,090	Level 2		1,395		1,677
Foreign currency exchange contracts—current liability		4		4	Level 2		—		—
Foreign currency exchange contracts—noncurrent liability		9		9	Level 2		—		—
Interest rate swap contracts—noncurrent liability		—		—	Level 2		1		1

        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. Upon issuance of the Company's exchangeable notes, a debt discount was recognized as a decrease in debt and an increase in equity. Accordingly, the Company's fair value and carrying value of long-term fixed rate debt as of June 28, 2013 is net of the unamortized discount of $20 million.

        The Company's foreign currency exchange contracts, commodity contracts, and interest rate swap contracts are recorded at fair value, using quoted currency forward rates, quoted commodity forward rates, and quoted interest rate curves, respectively, to calculate forward values, and then discounting 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 or swap interest 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 six months ended June 28, 2013.

Items Measured at Fair Value on a Nonrecurring Basis

        In addition to items that are measured at fair value on a recurring basis, and shown in the table above, the Company also has assets and liabilities in its balance sheet that are measured at fair value

18

TRW Automotive Holdings Corp.

Notes to Unaudited Condensed Consolidated Financial Statements (Continued)

8. Fair Value Measurements (Continued)

on a nonrecurring basis. Such assets and liabilities that are measured at fair value on a nonrecurring basis include long-lived assets, including investments in affiliates, which are written down to fair value as a result of impairment (see Note 11 for asset impairments).

        The Company has determined that the fair value measurements related to each of these assets and liabilities rely primarily on Company-specific inputs and the Company's assumptions about the use of the assets and settlement of liabilities, 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.

9. Financial Instruments

        The Company is exposed to certain financial market risks related to its ongoing business operations. The primary risks managed through derivative financial instruments and hedging activities are foreign currency exchange rate risk and interest rate risk. Derivative financial instruments and hedging activities are utilized to protect the Company's cash flow from adverse movements in foreign currency exchange rates, as well as to manage interest costs. 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 June 28, 2013, the Company had a notional value of $2.3 billion in foreign exchange contracts outstanding. These foreign exchange contracts mature at various dates through June 2016. Foreign currency exposures are reviewed monthly and any natural offsets are considered prior to entering into a derivative financial instrument.

        As of June 28, 2013, the Company had two offsetting interest rate swap agreements outstanding, each with a notional value of $25 million. The Company's exposure to interest rate risk arises primarily from changes in LIBOR.

        Derivative Instruments.    The fair values of the Company's derivative instruments as of June 28, 2013 and December 31, 2012 was $25 million and $40 million, respectively, in the asset position, and $34 million and $16 million, respectively, in the liability position. These amounts consist of interest rate contracts, foreign currency exchange contracts, and commodity contracts, none of which are individually significant.

        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 same period, or periods, during which the hedged transaction affects earnings. Gains and losses on the derivative representing either hedge ineffectiveness or hedge components excluded from the assessment of effectiveness are recognized in earnings. Approximately $5 million of losses, net of tax, which are included in OCI are expected to be reclassified into earnings in the next twelve months.

9. Financial Instruments (Continued)

        For the three and six months ended June 28, 2013, the effective portion of the gains and losses on derivatives designated as cash flow hedges and recognized in OCI was a loss of $33 million for both periods, all of which was related to foreign currency exchange contracts. The effective portion of gains and losses on cash flow hedges reclassified from OCI into the statement of earnings for the three and six months ended June 28, 2013 was a gain of $1 million for both periods, and was included in various line items on the statement of earnings.

        For the three and six months ended June 29, 2012, the effective portion of the gains and losses on derivatives designated as cash flow hedges and recognized in OCI was a loss of $30 million and a gain of $35 million, respectively, all of which was related to foreign currency exchange contracts. The effective portion of gains and losses on cash flow hedges reclassified from OCI into the statement of earnings for the three and six months ended June 29, 2012 was a loss of $2 million and $1 million, respectively, and was included in various line items on the statement of earnings.

        Gains or losses recognized in income related to hedge ineffectiveness for each of the three and six month periods ended June 28, 2013 and June 29, 2012 were not significant.

        Fair Value Hedges.    For any derivative instrument that is designated and qualifies as a fair value hedge, the gain or loss on the derivative as well as the offsetting loss or gain on the underlying hedged item is recognized in current earnings. For the three and six months ended June 28, 2013 and June 29, 2012, the Company had no fair value hedges outstanding.

        Undesignated Derivatives.    For the three and six months ended June 28, 2013, the Company recognized losses of $2 million and $3 million, respectively, in other (income) expense—net, for derivative instruments not designated as hedging instruments. For the three and six months ended June 29, 2012, the Company recognized losses of $6 million and gains of $10 million, respectively, 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. As of June 28, 2013, the Company had not posted any collateral to support its derivatives in a liability position.

        4.50% Senior Notes.    In February 2013, the Company issued $400 million in aggregate principal amount of 4.50% senior unsecured notes due 2021 (the "4.50% Senior Notes") in a private placement. Interest is payable semi-annually on March 1 and September 1 of each year beginning September 1, 2013. Net proceeds from the offering were approximately $394 million after deducting debt issuance costs.

10. Debt (Continued)

        8.875% Senior Notes.    In November 2009, the Company issued $250 million in aggregate original principal amount of 8.875% senior unsecured notes due 2017 (the "8.875% Senior Notes") in a private placement. Interest is payable semi-annually on June 1 and December 1 of each year. The 8.875% Senior Notes are redeemable in whole or in part on or after December 1, 2013 at a redemption price of 104.438% of par, which is reduced to 102.219% on December 1, 2014 and 100% on December 1, 2015 and thereafter.

        2007 Senior Notes.    In March 2007, the Company issued 7% senior unsecured notes and 6³/8% senior unsecured notes, each due March 2014, in original principal amounts of $500 million and €275 million, respectively, and 7¹/4% senior unsecured notes due 2017 in the original principal amount of $600 million (collectively, the "2007 Senior Notes") in a private placement. Interest is payable semi-annually on March 15 and September 15 of each year.

        Senior Note Repurchases.    During the three and six months ended June 28, 2013, the Company repurchased portions of its senior unsecured notes due in 2014 and 2017 totaling approximately $91 million in principal amount and recorded a loss on retirement of debt of $5 million. During the six months ended June 29, 2012, the Company repurchased portions of its senior unsecured notes due in 2014 and 2017 totaling approximately $48 million in principal amount and recorded a loss on retirement of debt of $5 million.

Exchangeable Senior Notes

        In November 2009, the Company issued approximately $259 million in aggregate principal amount of 3.50% exchangeable senior unsecured notes due 2015 (the "Exchangeable Senior Notes") in a private placement. Prior to September 1, 2015, the notes are exchangeable only upon specified events or conditions being met and, thereafter, at any time. One condition, the sales price condition (described below), was met as of June 28, 2013, and as such, the notes are exchangeable in the third quarter of 2013. They will remain exchangeable in subsequent quarters if the sale price condition continues to be met, which occurs if the last reported sale price of the Company's common stock for at least 20 of the last 30 trading days of the immediately preceding quarter is greater than 130% of the applicable exchange price. The initial exchange rate is 33.8392 shares of the Company's common stock per $1,000 principal amount of notes (equivalent to an exchange price of approximately $29.55 per share of common stock), subject to adjustment. Upon exchange, the Company's exchange obligation may be settled, at its option, in shares of its stock, cash or a combination of cash and shares of its stock. Interest is payable on June 1 and December 1 of each year. The Exchangeable Senior Notes will mature on December 1, 2015, unless earlier exchanged, repurchased by the Company at the holder's option upon a fundamental change, or redeemed by the Company after December 6, 2013, at the Company's option if certain conditions are met.

        The Exchangeable Senior Notes were recorded with a debt discount which decreased debt and increased paid-in-capital in order to separate the liability and embedded equity components. The debt component will accrete up to the principal amount to effectively yield 9.0% over the term of the debt. The debt discount as of June 28, 2013 and December 31, 2012 was $20 million and $24 million, respectively. The total interest expense recognized for the three and six months ended June 28, 2013 was approximately $4 million and $7 million, respectively, including $2 million and $3 million in each respective period relating to the stated coupon rate. The total interest expense recognized for the three

and six months ended June 29, 2012 was approximately $3 million and $6 million, respectively, including $2 million and $3 million in each respective period relating to the stated coupon rate.

Senior Secured Credit Facilities

        The Company's Eighth Amended and Restated Credit Agreement dated September 28, 2012 (the "Eighth Credit Agreement") provides for senior secured 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 and July 2017 (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").

        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 June 28, 2013 was 0.75% with respect to base rate borrowings and 1.75% with respect to eurocurrency borrowings. The commitment fee on the undrawn amounts under the Revolving Credit Facility was 0.30%.

Debt Repurchases

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

Other Borrowings

        The Company has borrowings under uncommitted credit agreements in many of the countries in which it operates. The borrowings are from various domestic and international banks at quoted market interest rates.

11. Restructuring Charges and Asset Impairments

        For the three months ended June 28, 2013, the Chassis Systems segment incurred $1 million of severance and other charges. For the six months ended June 28, 2013, the Company incurred restructuring charges of $38 million for severance and other charges as part of its ongoing efforts to better align its cost structure with global automotive market conditions. While the Chassis Systems segment and Occupant Safety Systems segment incurred $17 million and $27 million, respectively, of severance and other charges, the Automotive Components segment recorded $6 million of income related to changes in estimates for the six months ended June 28, 2013.

        For the three months ended June 29, 2012, the Automotive Components segment incurred $2 million of severance and other charges. For the six months ended June 29, 2012, the Chassis Systems segment and the Automotive Components segment each incurred $2 million of severance and other charges, together totaling $4 million.

Restructuring Reserves

        The following table illustrates the movement of the restructuring reserves for severance and other charges, including reserves related to severance-related postemployment benefits for both periods presented:

	Six Months Ended

Used for purposes intended		(43	)		(14	)
Effects of foreign currency translation		(1	)		(1	)
Ending balance	$	115		$	48

        Of the $115 million restructuring reserve as of June 28, 2013, approximately $91 million is expected to be paid in the remainder of 2013. The remaining balance is expected to be paid in 2014 to 2015 and is comprised primarily of involuntary employee termination arrangements in Europe.

12. 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 117,483,651 shares were issued and outstanding as of June 28, 2013 (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 SSARs and the vesting of RSUs issued as part of the Company's stock incentive plan (see Note 13).

        Share Repurchase Programs.    On February 16, 2012, the Company announced that its board of directors approved a share repurchase program that is intended to offset, on an ongoing basis, the dilution created by the Company's stock incentive plan (the "Anti-Dilution Program"). In addition, on October 1, 2012, the Company announced a share repurchase program that had been approved by its board of directors during the third quarter of 2012 to acquire up to $1 billion of the Company's outstanding common stock that extends through December 31, 2014.

        In May 2013, the Company entered into an accelerated share repurchase ("ASR") agreement with a third-party financial institution to repurchase the Company's common stock. Under the ASR agreement, the Company made an up-front payment of $125 million and received an initial delivery of approximately 1.7 million shares in the second quarter of 2013. The total number of shares to be ultimately delivered, and therefore the average price paid per share, will be determined at the end of the repurchase period based on the volume weighted average price of the Company's common stock during that period. The ASR will be completed during the third quarter of 2013.

        On February 22, 2013, the Company granted 1,199,551 SSARs to executive officers and certain employees of the Company pursuant to the TRW Automotive Holdings Corp. 2012 Stock Incentive Plan (the "2012 Plan"). Each SSAR entitles the grantee to receive the appreciation in value of one underlying share of the Company's stock from the grant date fair market value of $58.20 to the fair market value on the exercise date, although the stock price at exercise is limited to a maximum value of $110.00.

        On February 22, 2013, the Company also granted 428,169 RSUs to executive officers, independent directors and certain employees of the Company pursuant to the 2012 Plan. Additionally, the Company granted 4,400 phantom stock units ("PSUs") to certain employees of the Company. Each PSU entitles the grantee to receive a cash payment upon vesting equal to the fair market value on the vesting date of one share of the Company's common stock.

        As of June 28, 2013, the Company had 4,534,050 shares of Common Stock available for issuance under the 2012 Plan. In addition, 957,117 stock options, 3,207,642 SSARs, 820,764 nonvested RSUs and 15,300 nonvested PSUs were outstanding as of June 28, 2013. All of the SSARs and substantially all of the stock options have an 8-year term and vest ratably over three years, all the RSUs vest ratably over three years and a majority of the PSUs cliff vest after three years. As a result of changes to retirement eligibility provisions for awards granted in 2013, the Company applies a non-substantive vesting period approach whereby expense is accelerated for those employees that receive awards and are eligible to retire prior to the award vesting.

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

	Three Months Ended				Six Months Ended
	June 28, 2013		June 29, 2012		June 28, 2013		June 29, 2012

Cash Awards

        For both the three and six months ended June 28, 2013, the Company recognized approximately $1 million of compensation expense associated with its cash-settled share-based compensation awards described below. The comparable amount for the three and six months ended June 29, 2012 was de minimis and approximately $3 million, respectively. As of June 28, 2013, the liability and fair value

of the cash awards were de minimis and $1 million, respectively. As of December 31, 2012, the liability and fair value of the cash awards were $1 million and $3 million, respectively.

        2011 and 2010 Awards.    In February 2011 and March 2010, the Company issued cash incentive awards for executive officers (the "2011 Awards" and "2010 Awards", respectively). 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 agreement date. During the six months ended June 28, 2013, the second tranche of the 2011 Awards and the third tranche of the 2010 Awards vested and were fully paid. Subsequent to the payment of the second tranche, the target aggregate value of the awards granted in 2011 is approximately $1 million, but could range from a minimum value of zero to a maximum value of $1.2 million depending on movement of the Company's stock price during certain determination periods.

        2009 Awards.    In February 2009, the Company issued cash incentive awards for executive officers, vice presidents and independent directors and retention awards for executive officers and vice presidents of the Company (the "2009 Awards"). For compensation expense purposes, the fair value of the share-based portion of the 2009 Awards was determined based on a lattice model (the Monte Carlo simulation) and was re-measured quarterly. During the first quarter of 2012, approximately $40 million was paid to fully satisfy the obligation for these awards.

14. Related Party Transactions

        Secondary Offering.    In February 2013, Automotive Investors LLC ("AI LLC"), an affiliate of The Blackstone Group L.P. ("Blackstone"), and certain management stockholders sold 10 million shares of the Company's common stock in an underwritten registered public offering (the "Offering") pursuant to the Company's shelf registration statement on Form S-3 filed with the SEC on August 10, 2012. The Company did not receive any proceeds from the Offering, nor did its number of shares outstanding materially change. The Company incurred expenses in connection with the Offering which were de minimis. As a result of the Offering, AI LLC's ownership interest in the Company decreased to approximately 9%.

15. Segment Information

        In the first quarter of 2013, the Company began to manage and report certain components that were previously within its Electronics segment as part of its Chassis Systems segment. As a result, these components were reclassified and are now included within the Company's Chassis Systems segment. As such, the Company has made appropriate adjustments to its segment-related disclosures for 2013, as well as prior periods.

16. 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 June 28, 2013, the Company had reserves for environmental matters of $63 million. In addition, the Company has established a receivable from Northrop Grumman Corporation ("Northrop") for a portion of this environmental liability as a result of indemnification provided for in the master purchase agreement between Northrop and an affiliate of Blackstone under which Northrop has agreed to indemnify the Company for 50% of any environmental liabilities associated with the operation or ownership of the Company's automotive business existing at or prior to the acquisition, subject to certain exceptions. 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. However, the Company cannot predict the effect on the Company's financial position, results of operations or cash expenditures for aspects of certain matters for which there is insufficient information. In addition, the Company cannot predict the effect of compliance with environmental laws and regulations with respect to unknown environmental matters on the Company's financial statements or the possible effect of compliance with environmental requirements imposed in the future.

        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 2.

        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.

28

Notes to Unaudited Condensed Consolidated Financial Statements (Continued)

16. Contingencies (Continued)

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 matters 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 when the court approved a plea agreement between one of the Company's German subsidiaries and the DOJ. The Antitrust Investigation by the European Commission 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 the Company's 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.

        The Company has been named as a defendant in purported class action lawsuits filed on various dates from June 2012 through March 2013, which are now pending in the United States District Court for the Eastern District of Michigan, the Superior Court of Justice in Ontario, Canada and the Superior Court of Quebec, Canada on behalf of vehicle purchasers, lessors and dealers, alleging that the Company and certain of its competitors conspired to fix and raise prices for Occupant Safety Systems products. The Company intends to defend these cases vigorously. Management believes that the ultimate resolution of these cases will not have a material adverse effect on the Company's consolidated financial statements as a whole.

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, 2012, filed with the U.S. Securities and Exchange Commission on February 15, 2013, and the other information included herein. 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 86% of our end-customer sales in 2012 made to major OEMs. Of our 2012 sales, approximately 43% were in Europe, 36% were in North America, 17% were in Asia, and 4% were in the rest of the world.

Financial Results

        For the three months ended June 28, 2013:

•

Our net sales were $4.5 billion, which represents an increase of 6% compared to the prior year period. The higher level of sales was driven by increased demand for our active and passive safety products and growth in vehicle production in North America and China.

•

Operating income was $385 million compared to $337 million in the prior year period. The increase in operating income of $48 million resulted primarily from the positive impact of the higher level of sales, partially offset by planned cost increases to support future growth.

•

Net earnings attributable to TRW were $248 million as compared to $220 million in the prior year period. This increase of $28 million was primarily the result of the increase in operating income, partially offset by higher income tax expense.

•

During the quarter, we utilized $190 million of cash on hand to repurchase approximately 2.8 million shares of common stock under our share repurchase programs. We also utilized $96 million of cash on hand to optionally repurchase portions of our senior unsecured notes, totaling $91 million in principal amount.

        For the six months ended June 28, 2013:

•

Our net sales were $8.7 billion, which represents an increase of 3% compared to the prior year period. Increased demand for our active and passive safety products and growth in vehicle production in North America and China were partially offset by lower vehicle production volumes in Europe.

•

Operating income was $638 million compared to $668 million in the prior year period. The decrease in operating income of $30 million resulted primarily from increased restructuring charges, planned cost increases to support future growth and a higher proportion of lower margin business, partially offset by the positive impact of the higher level of sales.

30

•

Net earnings attributable to TRW were $410 million as compared to $426 million in the prior year period. This decrease of $16 million was primarily the result of the decline in operating income, partially offset by lower 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 macro-economic factors such as consumer confidence, fluctuating commodity and fuel prices and regulatory/governmental initiatives. The primary trends and market conditions impacting our business in 2013 include:

General Economic Conditions:

        During the first half of 2013, we remained cautiously optimistic as certain of the world's central banks continued easing policies to spur economic growth. In North America, the favorable economic environment suggests the recovery will continue at a modest pace. In Europe, weak consumer demand throughout the entire region has resulted in decreases in vehicle production levels. In China, despite signs the economy is beginning to moderate, the automotive industry continues to expand with automotive suppliers benefiting from increased production levels.

        Although there is evidence in the U.S. economy that the recovery is strengthening, global economic sentiment remains cautious given the ongoing sovereign debt crisis and recessionary conditions in Europe and indications of a slowing economy in China. The global automotive industry remains fragile and susceptible to uncertain economic conditions that could adversely impact consumer demand for vehicles.

Production Levels:

        Global vehicle production levels during the first half of 2013 were essentially flat compared to 2012, as a result of declines in Europe in excess of increased production in the rest of world. Vehicle production levels in North America increased slightly during the first half of 2013 compared to 2012.

        Approximately 43% of our sales originated in Europe during 2012. This region experienced lower production levels in the first half of 2013 compared to 2012, primarily as a result of decreased European consumer demand caused by weak consumer confidence related to the overall economic environment, as well as destocking of inventory as OEMs worked to align production with demand. Despite the slowing rate of decline in demand in the second quarter, signaling the industry may be stabilizing, we anticipate continuing negative economic conditions and normal seasonality within the euro zone to adversely influence vehicle demand and production in the second half of the year.

        Approximately 36% of our sales originated in North America during 2012. Production levels in this region increased slightly in the first half of 2013 compared to 2012. Production growth for the Detroit Three (defined as Chrysler Group LLC, Ford Motor Company, and General Motors Company, combined) was generally consistent with overall production growth within North America in the first half of 2013. In general, our financial results are more closely correlated to the production by the Detroit Three given our higher sales content to these manufacturers.

        Approximately 21% of our sales originated in regions outside of Europe and North America (primarily China, which comprised approximately 13% of total sales) during 2012. In China, production levels were higher in the first half of 2013 compared to the first half of 2012 due to increased consumer demand. We expect growth in production levels for the remainder of 2013 in Asia Pacific, especially in China.

31

Product Mix:

        Product mix tends to be influenced by a variety of factors such as gasoline prices, consumer income and wealth and governmental regulations (e.g. fuel economy standards driving higher volumes of small car production). In Europe, demand has historically tended to be toward smaller, more fuel efficient vehicles. In North America, product mix tends to be more correlated to short-term fluctuations in the price of gasoline and consumer sentiment and wealth, thereby causing production to swing between sport utility vehicles/light trucks and more economical passenger cars. For example, recent improvements in the North American housing market led to a higher level of light duty pickup truck production in the first half of 2013. In general, sport utility vehicles and light duty pickup trucks tend to be more profitable for OEMs and suppliers, while smaller, more fuel efficient vehicles tend to be less profitable.

Supply Base:

        As production levels fluctuate and overall economic concerns remain, Tier 2 and Tier 3 suppliers face the challenges of managing through variable working capital and capital expenditure requirements. With the declines in production in Europe, there are concerns about suppliers' viability stemming from broader industry restructuring actions. Further, in some cases, capacity constraints, limited availability of raw materials or components or financial instability of the Tier 2 and Tier 3 supply base poses a risk of supply disruption to us. We have experienced additional costs due to such factors and we may continue to incur such costs in the future.

        We have dedicated resources and systems to closely monitor the viability and performance of our supply base and are constantly evaluating opportunities to mitigate the risk and/or effects of any supplier disruption.

Inflation and Pricing Pressure:

        Overall commodity volatility is an ongoing concern for our business and has been a considerable operational and financial focus for us. As production levels rise, commodity inflationary pressures may increase, both in the automotive industry and in the broader economy. We continue to monitor commodity costs and work with our suppliers and customers to manage changes in such costs. However, when costs increase, it is generally difficult to pass the full extent of such increases for manufactured components and raw materials through to our customers in the form of price increases and, even if passed through to some extent, the recovery is typically on a delayed basis. Given the current environment, we do not expect to experience significant inflationary pricing pressure during 2013.

        Additionally, pressure from our customers to reduce prices is characteristic of the automotive supply industry. Virtually all OEMs have policies of seeking price reductions each year. Historically, we have taken steps to reduce costs and minimize or resist price reductions. However, to the extent our cost reductions are not sufficient to support committed price reductions, our profit margins could be negatively affected.

Foreign Currencies:

        During the first half of 2013, we did not experience a significant impact from foreign currency effects on our reported earnings in U.S. dollars compared to 2012. Further, our operating results will continue to be impacted by our buying, selling and borrowing in currencies other than the functional currency of our operating companies. In order to abate the impact of fluctuations in exchange rates between these currencies and to delay the impact of adverse exchange rate trends, we utilize hedging instruments where appropriate, taking into consideration their cost and effectiveness.

32

Strategic Initiatives

        In general, our long-term objectives are focused on profitably growing our business, expanding our newer, innovative technologies, winning new contracts, generating cash, strengthening our market position, and enhancing long-term shareholder value. On an ongoing basis, we evaluate our competitive position in the global automotive supply industry and determine what actions may be required to maintain and improve that position.

        As production levels rise in strategic growth markets such as China, we will continue to focus on investing appropriate levels of capital to support anticipated growth and expansion. These investments are critical as they position us to benefit from expected long-term growth opportunities.

        We believe that a continued focus on research, development and engineering activities is also critical to maintaining our leadership position in the industry and meeting our long-term objectives. Further, despite cautious global economic sentiment, we continue our commitment to invest in facilities and infrastructure in order to support new business awards and achieve our long-term growth plans, as evidenced by our expectation of continued increases in capital expenditures throughout 2013.

        We also continue to focus on our growth strategies, cash generation and capital structure improvement, while managing through the near-term industry challenges, such as the recessionary conditions in Europe.

        Although we believe that we have established a firm foundation for ongoing profitability, 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. Due to prolonged uncertainties in Europe, we continue to assess our cost base in the region and 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 in that region.

        We also regularly evaluate our operations and customer agreements to ensure alignment with our strategic and risk mitigation objectives. As part of this process, we are presently evaluating a supply agreement (the "Agreement") entered into with a major customer pertaining to certain of our North American brake component and assembly operations, which are included within our Chassis Systems segment. Upon completion of our assessment of the benefits, costs and risks associated with this Agreement, we may decide prior to September 15, 2013 to issue a notice to effectuate a "termination," as permitted under the Agreement. If we exercise this right, our exit from this business may result unless we are able to reach acceptable terms for continued supply with the customer. Restructuring and asset impairment charges estimated to be $15 million could be incurred in the second half of 2013. In 2012, these operations had revenues and a net earnings before tax margin of approximately $700 million and 6.5%, respectively.

Antitrust Investigations

        The U.S. Antitrust Investigation into our Occupant Safety Systems business was concluded when the court approved a plea agreement between one of our German subsidiaries and the DOJ. However, the Antitrust Investigation by the European Commission is ongoing and its duration and outcome remain uncertain. While we cannot estimate the ultimate financial impact of the European investigation, we will continue to evaluate developments in this matter on a regular basis and will record an accrual as and when appropriate.

Our Debt and Capital Structure

        During the first half of 2013, we continued to focus on improving the strength and flexibility of our capital structure, resulting in outstanding debt of $1.8 billion and a cash balance of $1.2 billion. In February 2013, we issued $400 million in aggregate principal amount of 4.50% senior unsecured notes

33

due 2021 in a private placement. Net proceeds from the offering were approximately $394 million after deducting debt issue costs. In addition, we reduced our debt by repurchasing $91 million in principal amount of our senior unsecured notes due in 2014 and 2017 in the second quarter of 2013.

        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 otherwise, or we may redeem such debt securities. Further, our 8.875% Senior Notes are redeemable in whole or in part at established redemption prices on or after December 1, 2013, and we may decide to initiate such a redemption.

        In 2012, the Company's board of directors approved a share repurchase program that is intended to offset, on an ongoing basis, the dilution created by our stock incentive plan for up to 1.5 million shares in 2013 and each subsequent year (the "Anti-Dilution Program"). The Company's board of directors also approved in 2012 a share repurchase program to acquire up to $1 billion of our outstanding common stock that extends through December 31, 2014. We are not obligated to repurchase any number of shares or dollar amount under either program, and the specific timing and amount of repurchases will vary based on market and business conditions and other factors. For the six months ended June 28, 2013 we utilized $200 million of cash on hand to repurchase approximately 3.0 million shares of common stock, a portion of which is subject to an additional final share settlement under an accelerated share repurchase ("ASR") program entered into in May 2013.

        See "LIQUIDITY AND CAPITAL RESOURCES" below, Part II, Item 2(c), "Issuer repurchases of equity securities," of this Report and Note 10 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 June 28, 2013 to the Three Months Ended June 29, 2012

Sales increased by $275 million, or 6%, for the three months ended June 28, 2013 as compared to the three months ended June 29, 2012. The increase in sales was driven by higher production volume primarily in North America, China and Brazil and increased global module sales, together totaling $251 million, and the favorable impact of foreign currency exchange of $36 million, partially offset by lower sales of $12 million related to a business divested in the third quarter of 2012.

        Changes in both vehicle production levels and our sales, by major geographic region in which we have our most significant sales, as compared to the prior year quarter are presented below:

	Variance
	Vehicle Production(a)			TRW Sales
North America		6	%		4	%
Europe		1	%		3	%
China and Brazil		13	%		26	%

        For the three months ended June 28, 2013, the change in TRW sales in North America was generally consistent with the vehicle production change in the region, given the composition of our customers and vehicle platforms. In Europe, sales were positively impacted by foreign currency exchange. Excluding the impact of foreign currency exchange, sales increased 1% in Europe, generally consistent with the vehicle production change in the region. In China and Brazil, the foreign exchange-adjusted increase in our sales was higher than the industry production increase due to a favorable concentration of customers and increased demand for our safety products.

Cost of sales increased by $220 million, or 6%, for the three months ended June 28, 2013 as compared to the three months ended June 29, 2012. The increase was driven primarily by additional costs associated with increased volume and non-commodity inflation, net of cost reductions, together which totaled $204 million as well as the unfavorable impact of foreign currency exchange of $30 million, partially offset by lower cost of sales of $14 million related to a business divested in the third quarter of 2012. These items resulted in the following variances to the major components within our cost of sales:

	(Dollars in millions)
Cost of sales, three months ended June 29, 2012	$	3,763
Material		168
Labor and other		48
Depreciation and amortization		4
Cost of sales, three months ended June 28, 2013	$	3,983

Gross profit, as a percentage of sales, for the three months ended June 28, 2013 was 11.8% compared to 11.2% for the three months ended June 29, 2012. This margin improvement was primarily driven by additional cost reductions and the favorable impact of foreign currency exchange, partially offset by costs to support future growth (such as increased engineering and other salary costs), a higher proportion of lower margin business, and higher warranty expense.

        Gross profit increased by $55 million for the three months ended June 28, 2013 as compared to the three months ended June 29, 2012. This increase was primarily driven by the favorable impact of higher volume (net of the proportion of lower margin business) of $54 million, the favorable impact of foreign currency exchange of $6 million and the elimination of a loss from a business divested in the third quarter of 2012 of $2 million, partially offset by increased non-commodity inflation, engineering, and other costs (net of cost reductions) of $7 million.

Administrative and selling expenses, as a percentage of sales, were 3.2% for the three months ended June 28, 2013 as compared to 3.4% for the three months ended June 29, 2012. There was no change in the total administrative and selling expense as compared to the same period in the prior year. A gain of $2 million recognized as a result of a curtailment of certain retiree medical and other benefits was offset by a net increase in share-based compensation and other expenses of $2 million.

Restructuring charges and asset impairments were $1 million for the three months ended June 28, 2013 compared to $2 million for the three months ended June 29, 2012, which related to severance and other charges in both periods.

Other income—net decreased by $7 million for the three months ended June 28, 2013 as compared to the three months ended June 29, 2012. This decrease was primarily due to the unfavorable impact of foreign currency exchange of $15 million, partially offset by the non-recurrence of a $5 million fine recorded for antitrust matters in the prior year period, and increased royalty and grant income of $2 million.

36

Interest expense—net increased by $7 million for the three months ended June 28, 2013 as compared to the three months ended June 29, 2012. The increase was primarily a result of increased debt levels, including the issuance of the 4.50% Senior Notes, and reduced interest income.

Loss on retirement of debt—net was $5 million for the three months ended June 28, 2013. During the three months ended June 28, 2013, we repurchased portions of our senior notes due in 2014 and 2017 totaling $91 million in principal amount and recorded a loss on retirement of debt of $5 million including the write-off of a portion of debt issue costs, discounts and premiums.

Income tax expense for the three months ended June 28, 2013 was $97 million on pre-tax earnings of $357 million as compared to an income tax expense of $92 million on pre-tax earnings of $319 million for the three months ended June 29, 2012. For both periods, the income tax rate varies from the United States statutory income tax rate primarily due to favorable foreign tax rates, holidays, and credits.

Comparison of the Six Months Ended June 28, 2013 to the Six Months Ended June 29, 2012

Sales increased by $280 million, or 3%, for the six months ended June 28, 2013 as compared to the six months ended June 29, 2012. The increase in sales was driven by higher production volume primarily in North America, China and Brazil (net of lower volume in Europe) and increased global module sales, together totaling $275 million, and the favorable impact of foreign currency exchange of $28 million, partially offset by lower sales of $23 million related to a business divested in the third quarter of 2012.

Source: Primarily IHS Automotive light vehicle production forecast.

        The change in sales in both North America and Europe for the six months ended June 28, 2013 was consistent with the change in vehicle production in the respective regions. In China and Brazil, the increase in our sales was higher than the industry production increase due to a favorable concentration of customers and increased demand for our safety products.

Cost of sales increased by $272 million, or 4%, for the six months ended June 28, 2013 as compared to the six months ended June 29, 2012. The increase was driven primarily by additional costs associated with increased volume and non-commodity inflation, net of cost reductions, together which totaled $273 million as well as the unfavorable impact of foreign currency exchange of $26 million, partially offset by lower cost of sales of $27 million related to a business divested in the third quarter of 2012. These items resulted in the following variances to the major components within our cost of sales:

	(Dollars in millions)
Cost of sales, six months ended June 29, 2012	$	7,497
Material		178
Labor and other		90
Depreciation and amortization		4
Cost of sales, six months ended June 28, 2013	$	7,769

Gross profit, as a percentage of sales, for the six months ended June 28, 2013 was 11.0% compared to 11.2% for the six months ended June 29, 2012. This margin contraction was primarily driven by a higher proportion of lower margin business, the increased costs to support growth plans (such as increased engineering and other salary costs), and the non-recurrence of a prior year favorable change in actuarially established recall loss projections due to improved historical claims data.

        Gross profit increased by $8 million for the six months ended June 28, 2013 as compared to the six months ended June 29, 2012. This increase was primarily driven by the favorable impact of higher volume (net of the proportion of lower margin business) of $56 million, the elimination of a loss from a business divested in the third quarter of 2012 of $4 million, and the favorable impact of foreign currency exchange of $2 million. Partially offsetting these favorable items was the unfavorable impact of increased non-commodity inflation, warranty, engineering, and other costs (net of cost reductions) of $38 million and the non-recurrence of a favorable change in actuarially established recall loss projections due to improved historical claims data of $16 million.

Administrative and selling expenses, as a percentage of sales, were 3.2% for the six months ended June 28, 2013 as compared to 3.4% for the six months ended June 29, 2012. The decrease of $8 million was primarily driven by favorable compensation and other expenses of $8 million, a gain of $6 million recognized as a result of a curtailment of certain retiree medical and other benefits, and lower legal fees for antitrust matters of $2 million. These decreases were partially offset by a net increase in share-based compensation of $8 million.

38

Restructuring charges and asset impairments were $38 million for the six months ended June 28, 2013 compared to $4 million for the six months ended June 29, 2012. This increase was driven by higher severance and other charges, primarily related to our continued restructuring efforts in Europe.

Other income—net decreased by $11 million for the six months ended June 28, 2013 as compared to the six months ended June 29, 2012. This decrease was primarily due to unfavorable impact of foreign currency exchange of $8 million, lower gains on sales of assets and divestures of $2 million, an increase in the provision for bad debts of $2 million, and the non-recurrence of miscellaneous other income of $4 million. These decreases were partially offset by the non-recurrence of a $5 million fine recorded for antitrust matters in the prior year period.

Interest expense—net increased by $8 million for the six months ended June 28, 2013 as compared to the six months ended June 29, 2012. The increase was primarily a result of increased debt levels, including the issuance of the 4.50% Senior Notes, and reduced interest income.

Loss on retirement of debt—net was $5 million for each of the six month periods ended June 28, 2013 and June 29, 2012. During the six months ended June 28, 2013 and June 29, 2012, we repurchased portions of our senior unsecured notes due in 2014 and 2017 totaling $91 million and $48 million, respectively, in principal amount and recorded a loss on retirement of debt of $5 million in both respective periods.

Income tax expense for the six months ended June 28, 2013 was $159 million on pre-tax earnings of $592 million as compared to an income tax expense of $185 million on pre-tax earnings of $627 million for the six months ended June 29, 2012. For the period ended June 28, 2013, 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 a discrete tax benefit recorded related to the enactment of the American Taxpayer Relief Act of 2012. The income tax rate for the period ended June 29, 2012 varies from the United States statutory income tax rate primarily due to favorable foreign tax rates, holidays, and credits.

        Earnings before taxes increased by $14 million for the three months ended June 28, 2013 as compared to the three months ended June 29, 2012. This increase was driven primarily by higher volume (net of a higher proportion of lower margin business) of $7 million, cost reductions (in excess of non-commodity inflation, engineering, and other costs) of $4 million, lower restructuring costs of $2 million, and the favorable impact of foreign currency exchange of $1 million.

Comparison of the six months ended June 28, 2013 and June 29, 2012:

Sales, including intersegment sales, increased by $29 million, or 3%, for the six months ended June 28, 2013 as compared to the six months ended June 29, 2012. This increase was primarily driven by higher volume of $21 million, as well as the favorable impact of foreign currency exchange of $8 million.

Cost of sales increased by $17 million, or 2%, for the six months ended June 28, 2013 as compared to the six months ended June 29, 2012, primarily consisting of higher material costs of $11 million and higher labor and other costs of $6 million. These increases were primarily driven by additional costs associated with higher volume, inflation and other costs of $11 million and the unfavorable impact of foreign currency exchange of $6 million.

44

Earnings before taxes, as a percentage of sales, was 8.7% for the six months ended June 28, 2013 compared to 6.6% for the six months ended June 29, 2012. This increase was primarily driven by cost reduction activities and the favorable profit impact of additional volume.

        Earnings before taxes increased by $23 million for the six months ended June 28, 2013 as compared to the six months ended June 29, 2012. This increase was driven primarily by lower restructuring costs of $8 million, the favorable profit impact of higher volume (net of a higher proportion of lower margin business) of $7 million, cost reductions (in excess of inflation, engineering, and other salary costs) of $5 million, and the favorable impact of foreign currency exchange of $3 million.

Restructuring charges and asset impairments decreased by $8 million for the six months ended June 28, 2013 as compared to the six months ended June 29, 2012. This decrease was primarily due to changes in estimates.

LIQUIDITY AND CAPITAL RESOURCES

        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.

        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 the other credit facilities described below, 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.

        As of June 28, 2013, the amount of cash and cash equivalents held by foreign subsidiaries was $795 million. If these funds were needed for our operations in the U.S., we would be required to provide for U.S. federal and state income tax, foreign income tax, and foreign withholding taxes on the funds repatriated. We have already provided for these taxes in accordance with Accounting Standard Codification ("ASC") 740-30-25 "Income Taxes" on a portion of these funds. However, for the remainder of the funds 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 provided by operating activities for the six months ended June 28, 2013 was $93 million as compared to cash provided by operating activities for the six months ended June 29, 2012 of $89 million. This increase of $4 million between the two periods was primarily the result of

45

lower cash outflows of other liabilities including customer pricing and warranty matters, the non-recurrence of employee benefit-related payments of $40 million, which included the payout for certain cash incentive and retention awards for executive officers and vice presidents that vested and were paid during the first quarter of 2012, partially offset by increased working capital requirements of $104 million and lower cash earnings.

        Investing Activities.    Cash used in investing activities for the six months ended June 28, 2013 was $271 million as compared to $190 million for the six months ended June 29, 2012.

        Capital expenditures were $271 million for the six months ended June 28, 2013 as compared to $200 million for the six months ended June 29, 2012. 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 approximately $740 million during 2013 on capital expenditures as we continue to invest in strategic growth.

        Financing Activities.    Cash provided by financing activities was $186 million for the six months ended June 28, 2013, as compared to cash used of $164 million for the six months ended June 29, 2012.

        During the six months ended June 28, 2013, we received $394 million of proceeds, net of fees, from the issuance of $400 million in aggregate principal amount of 4.50% senior unsecured notes. Additionally, during the first half of 2013, we used $200 million of cash on hand to repurchase approximately 3.0 million shares of our common stock. We also utilized $96 million of cash on hand to optionally repurchase portions of our senior unsecured notes, totaling $91 million in principal amount.

        During the six months ended June 29, 2012, we used $102 million of cash on hand to repurchase 2.3 million shares of our common stock. Also during the six months ended June 29, 2012, we utilized $53 million of cash on hand to optionally repurchase portions of our senior unsecured notes, totaling $48 million in principal amount.

Other Sources of Liquidity

        Liquidity Facilities.    We may draw down on, and use proceeds from, our revolving credit facility to fund normal working capital needs from month to month in conjunction with available cash on hand. As of June 28, 2013, we had $1.4 billion of availability under our revolving credit facility. This availability reflects no outstanding borrowings.

        On June 28, 2013, our subsidiaries in the Asia Pacific region also had various uncommitted credit facilities, of which $203 million was unutilized. We expect that these additional facilities will be drawn from time to time for normal working capital purposes and to fund capital expenditures in support of planned expansion in Asia Pacific.

        Under normal working capital utilization of liquidity, portions of the amounts drawn under our liquidity facilities typically are paid back throughout the month as cash from customers is received. We could then draw upon such facilities again for working capital purposes in the same or succeeding months.

        The agreement that governs our senior secured revolving credit facility 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 June 28, 2013, we were in compliance with all of our financial covenants. Such covenants are described in more detail in Note 12 to the consolidated financial statements included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2012.

        See "—Senior Secured Credit Facilities" in Note 10 to the unaudited condensed consolidated financial statements included in Part I, Item 1 of this Report for a description of our Revolving Credit Facility.

Contractual Obligations and Commitments

        During the six months ended June 28, 2013, there have been no material changes outside the ordinary course of our business to the contractual obligations previously disclosed in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2012 under "Management's Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources—Contractual Obligations and Commitments" except for the repurchase of portions of our senior unsecured notes and the issuance of new senior unsecured notes as described above under "—Cash Flows."

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 and other contingencies, including environmental contingencies and the amount currently held in reserve for environmental matters, contained in Note 16 to the unaudited condensed consolidated financial statements included in Part I, Item 1 of this Report is incorporated herein by reference.

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

        See Note 2 to the unaudited condensed consolidated financial statements included in Part I, Item 1 of this Report for a discussion of recently issued accounting pronouncements.

CRITICAL ACCOUNTING ESTIMATES

        There have been no significant changes in our critical accounting estimates during the six months ended June 28, 2013.

OUTLOOK

        For the full year 2013, we expect revenue to be in the range of approximately $16.8 billion to $17.0 billion, including third quarter sales of approximately $4.1 billion. These sales figures are based on expected 2013 production levels of 16.1 million units in North America, 18.6 million units in Europe, an increase in production levels in China and our expectations for foreign currency exchange rates.

        In North America, the industry recovery continues to trend in a positive direction with moderate growth. Despite signs of stabilization, in Europe, economic concerns and normal seasonality is expected to negatively impact vehicle production levels in the near-term. While we have implemented near-term, temporary cost containment actions, economic volatility will likely have a negative impact on our profitability, especially in the second half of the year, as we react to varying production levels. Growth in China and Brazil is expected to continue at a moderate pace for the remainder of the year. Considering expected long-term growth within these regions, we continue to invest appropriate levels of capital, engineering and infrastructure to underpin our expansion.

47

        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. Due to prolonged uncertainties in Europe, we continue to assess our cost base in the region and we intend to continue our restructuring initiatives to align our operations with the existing environment in that region. As a result, we expect to incur restructuring charges of approximately $50 million for the full year, which may include additional plant closures, targeted workforce reductions and adjustments to certain of our fixed costs, primarily in Europe. We believe these efforts are necessary actions in order to preserve our competitiveness and will provide lasting benefit over the long term.

        Further, we are currently evaluating an existing supply agreement with a major customer (the "Agreement") pertaining to certain of our North American brake component and assembly operations, which are included within our Chassis Systems segment. As previously discussed, we may decide to exercise our right to effect a termination of the Agreement, and our exit from this business may result unless we are able to reach acceptable terms for continued supply with the customer. Restructuring and asset impairment charges of $15 million (over and above our full year estimate) could be incurred in the second half of 2013. In 2012, these operations had revenues and a net earnings before tax margin of approximately $700 million and 6.5%, respectively.

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

        We continue to monitor the entire Tier 2 and Tier 3 supply base and its ability to perform as expected as it faces additional financial and operational challenges in the current environment due to variable production levels and economic concerns, particularly in Europe. The inability of any major supplier to meet its commitments could negatively impact us either directly or by negatively affecting our customers. We pursue alternate sources of supply where necessary and practicable.

        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.

        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.

        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 Annual Report on Form 10-K for the fiscal year ended December 31, 2012.

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 June 28, 2013, 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 second fiscal quarter of 2013 that has materially affected, or is reasonably likely to materially affect, the Company's internal control over financial reporting.

PART II—OTHER INFORMATION

Item 1.    Legal Proceedings

        The information concerning the ongoing antitrust matters and other legal proceedings involving the Company contained in Note 16 to the unaudited condensed consolidated financial statements included in Part I, Item 1 of this Report is incorporated herein by reference.

Item 1A.    Risk Factors

        There have been no material changes in the Company's risk factors from those previously disclosed in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2012.

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

(c)   Issuer repurchases of equity securities

        In its Annual Report on Form 10-K filed on February 16, 2012, the Company announced that its board of directors approved a share repurchase 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 2013 and each subsequent year (the "Anti-Dilution Program"). The Anti-Dilution Program does not have an expiration date. In addition, on October 1, 2012, the Company announced a share repurchase program that had been approved by its board of directors during the third quarter of 2012 to acquire up to $1 billion of the Company's outstanding common stock that extends through December 31, 2014. Both repurchase programs may be modified, suspended or terminated by the board of directors at any time without prior notice. The Company anticipates acquiring the shares under both programs from time to time through open market purchases, block trades, privately negotiated transactions including accelerated share repurchase transactions, other derivative transactions, or otherwise, at such times and in such amounts as Company management deems appropriate, given prevailing financial and market conditions. Repurchases may also be made under trading plan(s) that may be adopted from time to time in accordance with Rule 10b5-1 of the Securities Exchange Act, which would permit the Company to repurchase shares when it might otherwise be precluded from doing so under insider trading laws. However, the Company is not obligated to repurchase any shares under either program.

        In May 2013, the Company entered into an accelerated share repurchase ("ASR") agreement with a third-party financial institution to repurchase the Company's common stock. Pursuant to the ASR agreement, the Company made an up-front payment of $125 million, from cash on hand, to the financial institution and received an initial delivery of approximately 1.7 million shares in the second quarter of 2013. The total number of shares to be ultimately delivered, and therefore the average price paid per share, will be determined at the end of the repurchase period based on the volume weighted average price of the Company's common stock during that period. Under the ASR agreement, the repurchase period ends on July 31, 2013.

        The amounts available for us for share repurchases are restricted by our debt agreements. If our leverage ratio as defined in our senior secured credit facilities is greater than 1.5 to 1.0, our ability to repurchase shares of our common stock is restricted pursuant to a formula based on our consolidated net income. Certain of the indentures governing our outstanding notes also limit our ability to repurchase shares.

        The following table summarizes information relating to purchases of the Company's common stock made by or on behalf of the Company in accordance with both of its publicly announced repurchase

50

programs, including purchases made pursuant to the ASR agreement discussed above, one or more 10b5-1 trading plans and open market purchases, during the second quarter of 2013.

(a)

Monthly information is presented by reference to the Company's fiscal months during the second quarter of 2013, based upon settlement of each transaction.

(b)

All of the shares indicated were purchased under the Company's publicly announced repurchase programs, which consist of (i) the Anti-Dilution Program that was announced on February 16, 2012 and has no expiration date, pursuant to which up to 1.5 million shares may be repurchased in 2013 and each subsequent year, and (ii) the $1 billion repurchase program announced on October 1, 2012 that extends through December 31, 2014.

(c)

Excluding commissions.

(d)

The dollar values in this column reflect the $125 million up-front payment made under the ASR Agreement, and reflect the approximate dollar value of shares that may yet be purchased under the $1 billion repurchase program. During the three months ended June 28, 2013, the Company reached its 2012 board-authorized limit under the Anti-Dilution Program; however, additional shares may be purchased under the Anti-Dilution Program in 2014 and subsequent years.

(e)

Under the ASR agreement, the Company paid $125 million and received an initial delivery of approximately 1.7 million shares of its common stock in the second quarter of 2013. The average price paid per share reflected in the table for the ASR transaction was based upon the fair market value of the shares on the date the ASR agreement was executed. The total number of shares to be ultimately delivered, and therefore the average price paid per share, will be determined at the end of the repurchase period based on the volume weighted average price of the Company's common stock during that period. See Note 12 to the unaudited condensed consolidated financial statements included in Part I, Item 1 of this Report.

        In addition, the independent trustee of our 401(k) plans purchases shares in the open market to fund (i) investments by employees in our common stock, one of the investment options available under such plans, and (ii) matching contributions in Company stock we provide under certain of such plans. In addition, our stock incentive plan permits payment of an option exercise price by means of cashless exercise through a broker and permits the satisfaction of the minimum statutory tax obligations upon exercise of options through stock withholding. Further, while our stock incentive plan also permits the satisfaction of the minimum statutory tax obligations upon the vesting of restricted stock units and the exercise of stock-settled stock appreciation rights through stock withholding, the shares withheld for such purpose are issued directly to us and are then immediately retired and returned to our authorized but unissued reserve. The Company does not believe that the foregoing purchases or transactions are issuer repurchases for the purposes of Item 2 of this Report.

Goodwill and Intangible Assets

4. Goodwill and Intangible Assets

Goodwill

In the first quarter of 2013, the Company began to manage and report certain components that were previously within its Electronics segment as part of its Chassis Systems segment. As a result, these components were reclassified and are now included within the Company's Chassis Systems segment. As such, the Company has reallocated goodwill using a relative fair value allocation approach.

The changes in goodwill for the period are as follows:

			Occupant
	Chassis		Safety				Automotive
	Systems		Systems		Electronics		Components
	Segment		Segment		Segment		Segment		Total
	(Dollars in millions)
Balance as of December 31, 2012	$	796	$	537	$	423	$	-	$	1,756

Capital Stock [Abstract]

Capital Stock

12. 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 117,483,651 shares were issued and outstanding as of June 28, 2013 (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 SSARs and the vesting of RSUs issued as part of the Company's stock incentive plan (see Note 13).

Share Repurchase Programs. On February 16, 2012, the Company announced that its board of directors approved a share repurchase program that is intended to offset, on an ongoing basis, the dilution created by the Company's stock incentive plan (the “Anti-Dilution Program”). In addition, on October 1, 2012, the Company announced a share repurchase program that had been approved by its board of directors during the third quarter of 2012 to acquire up to $1 billion of the Company's outstanding common stock that extends through December 31, 2014.

In May 2013, the Company entered into an accelerated share repurchase (“ASR”) agreement with a third-party financial institution to repurchase the Company's common stock. Under the ASR agreement, the Company made an up-front payment of $125 million and received an initial delivery of approximately 1.7 million shares in the second quarter of 2013. The total number of shares to be ultimately delivered, and therefore the average price paid per share, will be determined at the end of the repurchase period based on the volume weighted average price of the Company's common stock during that period. The ASR will be completed during the third quarter of 2013.

During the three and six months ended June 28, 2013, the Company repurchased 2,752,228 shares and 2,950,828shares, respectively, of its common stockfor a total of $190 million and $200 million, respectively.During the three months ended June 28, 2013, the Company reached its 2012 board authorized limit under the Anti-Dilution Program to repurchase 1.5 million shares of its common stock; however, additional shares may be purchased under the program in subsequent years.

Basis of Presentation

2. 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, 2012, filed with the U.S. Securities and Exchange Commission (“SEC”) on February 15, 2013.

In the first quarter of 2013, the Company began to manage and report certain components that were previously within its Electronics segment as part of its Chassis Systems segment. As a result, these components were reclassified and are now included within the Company's Chassis Systems segment. As such, the Company has made appropriate adjustments to its segment-related disclosures for 2013, as well as prior periods.

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 and six months endedJune 28, 2013 are not necessarily indicative of results that may be expected for the year ending December 31, 2013.

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, restricted stock units (“RSUs”) and stock-settled stock appreciation rights (“SSARs”). Further, if the inclusion of shares potentially issuable for the Company's 3.50% exchangeable senior unsecured notes (see Note 10) 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:
			Three Months Ended				Six Months Ended
			June 28,		June 29,		June 28,		June 29,
			2013		2012		2013		2012
			(In millions, except per share amounts)
	Net earnings attributable to TRW		$	248	$	220	$	410	$	426
	Interest expense on exchangeable notes, net of tax			1		1		2		2
	Amortization of discount on exchangeable notes, net of tax			1		1		2		2
	Net earnings attributable to TRW for purposes of calculating diluted earnings per share		$	250	$	222	$	414	$	430
	Basic:
		Weighted average shares outstanding		118.9		122.5		119.2		123.1
		Basic earnings per share	$	2.09	$	1.80	$	3.44	$	3.46
	Diluted:
		Weighted average shares outstanding		118.9		122.5		119.2		123.1
		Effect of dilutive stock options, RSUs and SSARs		1.0		1.2		1.2		1.4
		Shares applicable to exchangeable notes		5.9		5.9		5.9		5.9
		Diluted weighted average shares outstanding		125.8		129.6		126.3		130.4
		Diluted earnings per share	$	1.99	$	1.71	$	3.28	$	3.30

For both the three and six months ended June 28, 2013, approximately 1.6 million securitieswere excluded from the calculation of diluted earnings per share because the inclusion of such securities in the calculation would have been anti-dilutive.

For the three and six months ended June 29, 2012, approximately 2.9 million and 2.4 million securities, respectively, were excluded from the calculation of diluted earnings per share because the inclusion of such securities in the calculation would have been anti-dilutive.

Fair Value Measurements [Abstract]

Fair Value Measurements

8. Fair Value Measurements

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. The Company utilizes the market approach to determine the fair value of its assets and liabilities under Level 1 of the fair value hierarchy. The market approach pertains to transactions in active markets involving identical or comparable assets or liabilities.

       Level 2. The fair values determined through Level 2 of the fair value hierarchy are 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.

       Level 3. The Company utilizes the income approach or the cost approach, as appropriate, to determine the fair value of its assets and liabilities under Level 3 of the fair value hierarchy. The fair value is derived principally from unobservable inputs from the Company's own assumptions about market risk, developed based on the best information available, subject to cost-benefit analysis, and may include the Company's own data. When there are pension related assets with fair value determined through Level 3, fair value is derived principally from unobservable inputs provided by the trustee. When there are no observable comparables, inputs used to determine value are derived from Company-specific inputs, such as projected financial data and the Company's own views about the assumptions that market participants would use.

Items Measured at Fair Value on a Recurring Basis
The fair value measurements for assets and liabilities recognized in the Company’s consolidated balance sheets are as follows:
		As of
		June 28, 2013					December 31, 2012
		Carrying		Fair		Measurement	Carrying		Fair
		Value		Value		Approach	Value		Value
		(Dollars in millions)
	Foreign currency exchange contracts — current assets	$	4	$	4	Level 2	$	16	$	16
	Foreign currency exchange contracts — noncurrent assets		-		-	Level 2		9		9
	Short-term debt, fixed and floating rate		87		87	Level 2		67		67
	Fixed rate long-term debt		1,769		2,090	Level 2		1,395		1,677
	Foreign currency exchange contracts — current liability		4		4	Level 2		-		-
	Foreign currency exchange contracts — noncurrent liability		9		9	Level 2		-		-
	Interest rate swap contracts — noncurrent liability		-		-	Level 2		1		1

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. Upon issuance of the Company's exchangeable notes, a debt discount was recognized as a decrease in debt and an increase in equity. Accordingly, the Company's fair value and carrying value of long-term fixed rate debt as of June 28, 2013is net of the unamortized discount of $20million.

The Company's foreign currency exchange contracts, commodity contracts, and interest rate swap contracts are recorded at fair value, using quoted currency forward rates, quoted commodity forward rates, and quoted interest rate curves, respectively, to calculate forward values, and then discounting 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 or swap interest 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 sixmonths ended June 28, 2013.

Items Measured at Fair Value on a Nonrecurring Basis

In addition to items that are measured at fair value on a recurring basis, and shown in the table above, the Company also has assets and liabilities in its balance sheet that are measured at fair value on a nonrecurring basis. Such assets and liabilities that are measured at fair value on a nonrecurring basis include long-lived assets, including investments in affiliates, which are written down to fair value as a result of impairment (see Note 11 for asset impairments).

The Company has determined that the fair value measurements related to each of these assets and liabilities rely primarily on Company-specific inputs and the Company's assumptions about the use of the assets and settlement of liabilities, 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.

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, restricted stock units (“RSUs”) and stock-settled stock appreciation rights (“SSARs”). Further, if the inclusion of shares potentially issuable for the Company's 3.50% exchangeable senior unsecured notes (see Note 10) 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.

Senior Notes

4.50% Senior Notes. In February 2013, the Company issued $400 million in aggregate principal amount of 4.50% senior unsecured notes due 2021 (the “4.50% Senior Notes”) in a private placement. Interest is payable semi-annually on March 1 and September 1 of each year beginning September 1, 2013. Net proceeds from the offering were approximately $394 million after deducting debt issuance costs.

8.875% Senior Notes. In November 2009, the Company issued $250 million in aggregate original principal amount of 8.875% senior unsecured notes due 2017 (the “8.875% Senior Notes”) in a private placement. Interest is payable semi-annually on June 1 and December 1 of each year. The 8.875% Senior Notes are redeemable in whole or in part on or after December 1, 2013 at a redemption price of 104.438% of par, which is reduced to 102.219% on December 1, 2014 and 100% on December 1, 2015 and thereafter.

2007 Senior Notes. In March 2007, the Company issued 7% senior unsecured notes and 6⅜% senior unsecured notes, each due March 2014, in original principal amounts of $500 million and €275 million, respectively, and 7¼% senior unsecured notes due 2017 in the original principal amount of $600 million (collectively, the “2007 Senior Notes”) in a private placement. Interest is payable semi-annually on March 15 and September 15 of each year.

Senior Note Repurchases. During the three and six months ended June 28, 2013, the Company repurchased portions of its senior unsecurednotes due in 2014 and 2017totaling approximately $91 million in principal amount and recorded a loss on retirement of debt of $5 million. During thesix months ended June 29, 2012,the Company repurchased portions of its senior unsecured notes due in 2014 and 2017 totaling approximately $48 million in principal amount and recorded a loss on retirement of debt of $5 million.

Exchangeable Senior Notes

In November 2009, the Company issued approximately $259 million in aggregate principal amount of 3.50% exchangeable senior unsecured notes due 2015 (the “Exchangeable Senior Notes”) in a private placement. Prior to September 1, 2015, the notes are exchangeable only upon specified events or conditions being met and, thereafter, at any time. One condition, the sales price condition (described below), was met as of June 28, 2013, and as such, the notes are exchangeable in the thirdquarter of 2013. They will remain exchangeable in subsequent quarters if the sale price condition continues to be met, which occurs if the last reported sale price of the Company's common stock for at least 20 of the last 30 trading days of the immediately preceding quarter is greater than 130% of the applicable exchange price. The initial exchange rate is 33.8392 shares of the Company's common stock per $1,000 principal amount of notes (equivalent to an exchange price of approximately $29.55 per share of common stock), subject to adjustment. Upon exchange, the Company's exchange obligation may be settled, at its option, in shares of its stock, cash or a combination of cash and shares of its stock. Interest is payable on June 1 and December 1 of each year. The Exchangeable Senior Notes will mature on December 1, 2015, unless earlier exchanged, repurchased by the Company at the holder's option upon a fundamental change, or redeemed by the Company after December 6, 2013, at the Company's option if certain conditions are met.

The Exchangeable Senior Notes were recorded with a debt discount which decreased debt and increased paid-in-capital in order to separate the liability and embedded equity components. The debt component will accrete up to the principal amount to effectively yield 9.0% over the term of the debt. The debt discount as of June 28, 2013and December 31, 2012 was $20 million and $24 million, respectively. The total interest expense recognized for the three and six months ended June 28, 2013was approximately $4 million and $7 million, respectively, including $2 million and $3 million in each respective period relating to the stated coupon rate. The total interest expense recognized for the three and six months ended June 29, 2012 was approximately $3 millionand $6 million, respectively, including $2 million and $3 million in each respective period relating to the stated coupon rate.

Senior Secured Credit Facilities

The Company's Eighth Amended and Restated Credit Agreement dated September 28, 2012 (the “Eighth Credit Agreement”) provides for senior secured 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 conditionsbeing met in October 2016 and July 2017 (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”).

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 ofJune 28, 2013was0.75% with respect to base rate borrowings and 1.75% with respect to eurocurrency borrowings. The commitment fee on the undrawn amounts under the Revolving Credit Facility was 0.30%.

Debt Repurchases

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

Other Borrowings

The Company has borrowings under uncommitted credit agreements in many of the countries in which it operates. The borrowings are from various domestic and international banks at quoted market interest rates.

Income Taxes

6. 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 certain 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 June 28, 2013 was $97 million on pre-tax earnings of $357 million and income tax expense for the six months ended June 28, 2013 was $159 million on pre-tax earnings of $592 million. Income tax expense for the three months ended June 29, 2012 was $92 million on pre-tax earnings of $319 million and income tax expense for the six months ended June 29, 2012 was $185 million on pre-tax earnings of $627 million. Income tax expense for the three months ended June 28, 2013 includes a net tax benefit of $4 million relating to the resolution of various tax matters in foreign jurisdictions. Income tax expense for the six months ended June 28, 2013 includes a tax benefit of $12 million relating to the enactment of the American Taxpayer Relief Act of 2012 (as discussed below), a net tax benefit of $4 million relating to the resolution of various tax matters in foreign jurisdictions, and a net tax expense relating to other discrete tax items, resulting in a net tax benefit of $8 million for the period. For the period endedJune 28, 2013, 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 enactment of theAmerican Taxpayer Relief Act of 2012.

The Company reviews the likelihood that it will realize the benefit of its deferred tax assets and, therefore, the need for valuation allowances on a quarterly basis, or more frequently if events indicate that a review is required. In determining the requirement for a valuation allowance, the historical and projected financial results of the legal entity or consolidated group recording the net deferred tax asset is considered, along with all other available positive and negative evidence. The Company utilizes a rolling twelve quarters of pre-tax results adjusted for significant permanent book to tax differences as a measure of cumulative results in recent years. The factors considered by management in its determination of the probability of the realization of the deferred tax assets include but are not limited to: recent historical financial results, historical taxable income, projected future taxable income, the expected timing of the reversals of existing temporary differences and tax planning strategies. If, based upon the weight of available evidence, it is more likely than not the deferred tax assets will not be realized, a valuation allowance is recorded. If operating results improve or deteriorate on a sustained basis, the Company'sconclusions regarding the need for a valuation allowance could change, resulting in either the reversal or initial recognition of a valuation allowance in the future, which could have a significant impact on income tax expense in the period recognized and subsequent periods. The recent U.S. economic recovery and improvement in the North American automotive market, along with improved Company performance, have all had a favorable impact on U.S. operating results. If such performance continues, the Company may be in a position, in future periods, to utilize certain historical foreign tax credits in excess of previous expectations, which could have a significant favorable impact on income tax expense in the period recognized.

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 statute 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 effect this may have upon the gross unrecognized tax benefits.

On January 2, 2013, the American Taxpayer Relief Act of 2012 was enacted, which retroactively reinstated and extended various tax provisions applicable to the Company, including the research and development tax credit and the look through rules for controlled foreign corporations. The effect of a tax law change, including any retroactive effect, is accounted for in the period of enactment. As a result, the Company recorded a discrete tax benefitduring the first quarter related to this legislation.

On July 17, 2013, the United Kingdom – Finance Bill of 2013 received Royal Assent, thereby becoming law as the Finance Act 2013 (the “Act”). The Act provides for a reduction to the corporate income tax rate from 23% to 21% effective April 1, 2014, with a further reduction to 20% effective April 1, 2015. The impact of this legislation will be recorded as a discrete item during the third quarter, the period of enactment, and will result in a tax benefit of approximately $20 million.

On February 22, 2013, the Company granted 1,199,551 SSARs to executive officers and certain employees of the Company pursuant to theTRW Automotive Holdings Corp. 2012 Stock Incentive Plan (the “2012 Plan”). Each SSAR entitles the grantee to receive the appreciation in value of one underlying share of the Company's stock from the grant date fair market value of $58.20 to the fair market value on the exercise date, although the stock price at exercise is limited to a maximum value of $110.00.

On February 22, 2013, the Company also granted 428,169 RSUs to executive officers, independent directors and certain employees of the Company pursuant to the 2012Plan. Additionally, the Company granted 4,400 phantom stock units (“PSUs”) to certain employees of the Company. Each PSU entitles the grantee to receive a cash payment upon vesting equal to the fair market value on the vesting date of one share of the Company's common stock.

As of June 28, 2013, the Company had 4,534,050 shares of Common Stock available for issuance under the 2012 Plan. In addition,957,117 stock options,3,207,642SSARs,820,764nonvestedRSUs and 15,300nonvested PSUs were outstanding as of June 28, 2013.

Cash Awards

For both the three and six months ended June 28, 2013, the Company recognized approximately $1 million of compensation expense associated with its cash-settled share-based compensation awards described below. The comparable amount for the three and six months ended June 29, 2012 was de minimis and approximately $3 million, respectively. As of June 28, 2013, the liability and fair value of the cash awards werede minimis and $1 million, respectively. As of December 31, 2012, the liability and fair value of the cash awards were $1 million and $3 million, respectively.

2011 and 2010 Awards. In February 2011 and March 2010, the Company issued cash incentive awards for executive officers (the “2011 Awards” and “2010 Awards”, respectively). 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 agreement date. During the six months ended June 28, 2013, the second tranche of the 2011 Awards and the third tranche of the 2010 Awards vested and were fully paid. Subsequent to the payment of the second tranche, the target aggregate value of the awards granted in 2011 is approximately $1 million, but could range from a minimum value of zero to a maximum value of $1.2 million depending on movement of the Company's stock price during certain determination periods.

2009 Awards. In February 2009, the Company issued cash incentive awards for executive officers, vice presidents and independent directors and retention awards for executive officers and vice presidents of the Company (the “2009 Awards”). For compensation expense purposes, the fair value of the share-based portion of the 2009 Awards was determined based on a lattice model (the Monte Carlo simulation) and was re-measured quarterly. During the first quarter of 2012, approximately $40 million was paid to fully satisfy the obligation for these awards.

Financial Instruments [Abstract]

Financial Instruments

9. Financial Instruments

The Company is exposed to certain financial market risks related to its ongoing business operations. The primary risks managed through derivative financial instruments and hedging activities are foreign currency exchange rate risk and interest rate risk. Derivative financial instruments and hedging activities are utilized to protect the Company's cash flow from adverse movements in foreign currency exchange rates, as well as to manage interest costs. 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 June 28, 2013, the Company had a notional value of $2.3 billion in foreign exchange contracts outstanding. These foreignexchange contracts mature at various dates through June 2016. Foreign currency exposures are reviewed monthly and any natural offsets are considered prior to entering into a derivative financial instrument.

As of June 28, 2013, the Company had two offsetting interest rate swap agreements outstanding, each with a notional value of $25 million. The Company's exposure to interest rate risk arises primarily from changes in LIBOR.

Derivative Instruments. The fair values of the Company's derivative instruments as of June 28, 2013 and December 31, 2012 was $25 million and $40 million, respectively, in the asset position, and $34 million and $16 million, respectively, in the liability position. These amounts consist of interest rate contracts, foreign currency exchange contracts, and commodity contracts, none of which are individually significant.

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 same period, or periods, during which the hedged transaction affects earnings. Gains and losses on the derivative representing either hedge ineffectiveness or hedge components excluded from the assessment of effectiveness are recognized in earnings. Approximately $5 million of losses, net of tax, which are included in OCI are expected to be reclassified into earnings in the next twelve months.

       For the three and six months ended June 28, 2013, the effective portion of the gains and losses on derivatives designated as cash flow hedges and recognized in OCI was a loss of $33 million for both periods, all of which was related to foreign currency exchange contracts. The effective portion of gains and losses on cash flow hedges reclassified from OCI into the statement of earnings for the three and six months ended June 28, 2013 was a gain of $1 million for both periods, and was included in various line items on the statement of earnings.

       For the three and six months ended June 29, 2012, the effective portion of the gains and losses on derivatives designated as cash flow hedges and recognized in OCI was a loss of $30 million and a gain of $35 million, respectively, all of which was related to foreign currency exchange contracts. The effective portion of gains and losses on cash flow hedges reclassified from OCI into the statement of earnings for the three and six months ended June 29, 2012 was a loss of $2 million and $1 million, respectively, and was included in various line items on the statement of earnings.

       Gains or losses recognized in income related to hedge ineffectiveness for each of the three and six month periods ended June 28, 2013 and June 29, 2012 were not significant.

Fair Value Hedges. For any derivative instrument that is designated and qualifies as a fair value hedge, the gain or loss on the derivative as well as the offsetting loss or gain on the underlying hedged item is recognized in current earnings. For the three and six months ended June 28, 2013 and June 29, 2012, the Company had no fair value hedges outstanding.

Undesignated Derivatives. For the three and six months ended June 28, 2013, the Company recognized losses of $2 million and $3 million, respectively, in other (income) expense – net, for derivative instruments not designated as hedging instruments. For the three and six months ended June 29, 2012, the Company recognized losses of $6 million and gains of $10 million, respectively, 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. As of June 28, 2013, the Company had not posted any collateral to support its derivatives in a liability position.

Contingencies [Abstract]

Contingencies

16. 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 June 28, 2013, the Company had reserves for environmental matters of $63 million. In addition, the Company has established a receivable from Northrop Grumman Corporation (“Northrop”) for a portion of this environmental liability as a result of indemnification provided for in the master purchase agreement between Northrop and an affiliate of Blackstone under which Northrop has agreed to indemnify the Company for 50% of any environmental liabilities associated with the operation or ownership of the Company's automotive business existing at or prior to the acquisition, subject to certain exceptions. 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. However, the Company cannot predict the effect on the Company's financial position, results of operations or cash expenditures for aspects of certain matters for which there is insufficient information. In addition, the Company cannot predict the effect of compliance with environmental laws and regulations with respect to unknown environmental matters on the Company's financial statements or the possible effect of compliance with environmental requirements imposed in the future.

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 2.

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 matters 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, whichwas concluded when the court approved a plea agreement between one of the Company's German subsidiaries and the DOJ. The Antitrust Investigation by the European Commission 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 the Company's 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.

The Company has been named as a defendant in purported class action lawsuits filed on various dates from June 2012 through March 2013, which are now pending in the United States District Court for the Eastern District of Michigan, the Superior Court of Justice in Ontario, Canada and the Superior Court of Quebec, Canada on behalf of vehicle purchasers, lessors and dealers, alleging that the Company and certain of its competitors conspired to fix and raise prices for Occupant Safety Systems products. The Company intends to defend these cases vigorously. Management believes that the ultimate resolution of these cases will not have a material adverse effect on the Company's consolidated financial statements as a whole.
