REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Pension Administrative Committee of the
TRW Automotive Retirement Savings Plan for Hourly Employees

We have audited the accompanying statements of net assets available for benefits of TRW Automotive Retirement Savings Plan for Hourly Employees as of December 31, 2010 and 2009, and the related statement of changes in net assets available for benefits for the year ended December 31, 2010. These financial statements are the responsibility of the Plan’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. We were not engaged to perform an audit of the Plan’s internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Plan’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the net assets available for benefits of the Plan at December 31, 2010 and 2009, and the changes in its net assets available for benefits for the year ended December 31, 2010, in conformity with US generally accepted accounting principles.

Our audits were performed for the purpose of forming an opinion on the financial statements taken as a whole. The accompanying supplemental schedule of assets (held at end of year) as of December 31, 2010, is presented for purposes of additional analysis and is not a required part of the financial statements but is supplementary information required by the Department of Labor’s Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. This supplemental schedule is the responsibility of the Plan’s management. The supplemental schedule has been subjected to the auditing procedures applied in our audits of the financial statements and, in our opinion, is fairly stated in all material respects in relation to the financial statements taken as a whole.

TRW Automotive
Retirement Savings Plan for Hourly Employees

Notes to Financial Statements

As of December 31, 2010 and 2009, and for the Year Ended December 31, 2010

1. Description of Plan

The following description of the TRW Automotive Retirement Savings Plan for Hourly Employees (the Plan) provides only general information. Participants should refer to the Summary Plan Description for a more complete description of the Plan’s provisions.

General

The Plan is a defined-contribution benefit plan designed to provide eligible employees of a participating plant, division, subsidiary, or affiliate of Kelsey-Hayes Company, the sponsor of the Plan, with a vehicle to systematically save funds to supplement their retirement benefits. Kelsey-Hayes Company (as applicable, the Company or TRW) is a wholly owned subsidiary of TRW Automotive, Inc. The Plan is subject to the Employee Retirement Income Security Act of 1974 (ERISA).

Eligibility

Hourly employees covered by collective bargaining agreements are eligible to participate in the Plan based on the terms of the applicable collective bargaining agreements, generally after one year of service. Non-union employees of the specified locations in the Plan document are eligible to participate in the Plan on the first day of employment with the Company. Non-union employees are eligible to participate in the Plan for purposes of receiving the Company match after completing one year of service.

Employee Contributions

Each year, participants may contribute a percentage of pretax annual compensation not to exceed the applicable Internal Revenue Service (IRS) limitations ($16,500 for both 2010 and 2009). Participants may also contribute amounts representing distributions from other qualified defined-benefit or defined-contribution plans. For 2010 and 2009, a participant who was 50 years old on or before the last day of the Plan year-end was eligible to make an additional catch-up contribution of $5,500.

Upon enrollment, a participant may direct contributions in 1% increments to any of the Plan’s fund options. Participants may change their investment options or transfer assets between investment options at any time during the year.

1. Description of the Plan (continued)

Employer Contributions

The Company contributes an amount equal to 50% of the participant’s pretax contribution up to 6% of the participant’s compensation for the vast majority of hourly participants. The company also contributes to the following bargaining groups:

Mt. Vernon hourly participants: the Company contributes thirty cents ($0.30) for each hour that a participant was compensated during the month provided the participant made pretax contributions to the Plan of 1% or more for employees under the Mt. Vernon collective bargaining agreement. The Mt. Vernon facility closed in July 2010.

Fayette hourly participants: the Company does not make matching contributions. Effective January 1, 2011, the Company will contribute 50% of the participant’s pretax contributions up to 4% of the participant’s compensation for employees under the Fayette collective bargaining agreement.

Saginaw hourly participants: the Company contributes to the Plan an amount equal to 30% of the first 7% of the employee’s elective deferral contributions for hourly employees of TRW Integrated Chassis Systems LLC.

Matching contributions made in TRW Automotive Holdings Corp. stock prior to January 1, 2007, are subject to the Pension Protection Act (PPA) transition rule, which states matching contributions made in company stock before January 1, 2007, may be transferred to another available investment option over a three-year period (33% in 2007, 66% in 2008 and 100% in 2009). For years after January 1, 2007, the matching contributions in TRW Automotive Holdings Corp. stock become diversifiable after attaining three years of service.

Company matching contributions were suspended for non-union hourly participants for payroll periods beginning after February 27, 2009, and resumed with the payroll payment dated February 12, 2010.

1. Description of the Plan (continued)

Participant Accounts

Each participant’s account is credited with the participant’s contributions, the Company’s contribution, if applicable, and the Plan’s earnings. The benefit to which a participant is entitled cannot exceed the participant’s vested account balance.

Vesting

Participants are immediately vested in their contributions plus actual earnings thereon. For Company matching contributions, a participant is 20% vested each year of credited service and is 100% vested after five years of credited service if hired before August 1, 2007.

If hired after August 1, 2007, vesting in Company contributions will be 20% each year beginning with the second year of employment and will be 100% vested after six years of credited service. Full vesting also occurs upon death, permanent disability, or retirement.

Forfeitures

Nonvested employer contributions of terminated employees become forfeitures after a one-year break in service and shall be used to reduce future employer contributions or administrative expenses. Forfeited funds are transferred to the Fidelity Managed Income Portfolio II fund. Approximately $13,740 and $6,738 was available to pay additional Plan expenses at December 31, 2010 and 2009, respectively.

Notes Receivable from Participants

Participants may borrow an amount limited to the lesser of 50% of their vested account balance or $50,000. The loan terms range from 1 to 5 years or up to 10 years for the purchase of a primary residence. The loans are secured by the balance in the participant’s account and bear interest at a prime interest rate on the last business day of the preceding quarter (as published in the Wall Street Journal) plus one percentage point. Principal and interest are paid ratably through regular payroll deductions.

Defaulted loans are classified as either an actual distribution or deemed distribution. An actual distribution occurs if the participant was eligible to receive all or part of the loan as a distribution. Whereas, a deemed distribution occurs if a participant was not eligible to receive a distribution from the Plan.

1. Description of the Plan (continued)

Payment of Benefits

Upon retirement, disability, or death, the entire balance of the participant’s account becomes payable to the participant or the participant’s beneficiary. Upon any other termination of employment, the participant receives the vested portion of his or her account. Financial hardship withdrawals and in-service withdrawals are permitted as defined by the plan.

Hardship withdrawals are allowed for participants incurring an immediate and heavy financial need, as defined by the Plan. Hardship withdrawals are strictly regulated by the Internal Revenue Service (IRS) and a participant must exhaust all available loan options and available distributions prior to requesting a hardship withdrawal.

In-service withdrawals are available either from the participant’s after-tax contributions and/or roller over contributions or upon attainment of age 59 1/2 under certain provisions of the Plan.

Administrative Expenses

Certain administrative expenses of the Plan related to loan set-up, withdrawals, and qualified domestic relation orders are paid by the participants. Most other administrative expenses are paid for by the Company.

Plan Termination

The Company has the right under the Plan to terminate the Plan subject to the provisions of ERISA and the respective collective bargaining agreements. In the event of Plan termination, participants will become 100% vested in their accounts and distributions to participants and beneficiaries will be made at such time after termination of the Plan as provided by the Plan agreement.

1. Description of the Plan (continued)

Effective December 2010, the Fidelity Managed Income Portfolio is frozen to new investments. This fund was replaced by the Fidelity Managed Income Portfolio II.

Effective April 2011, the Alliance Bernstein International Value Fund Class A was replaced by the Dodge & Cox International Stock Fund.

2. Summary of Significant Accounting Policies

Use of Estimates

The preparation of the financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates that affect the amounts reported in the financial statements and accompanying notes and supplemental schedule. Actual results could differ from those estimates.

Excess Contributions Payable

Amounts payable to participants for contributions in excess of amounts allowed by the IRS are recorded as a liability with a corresponding reduction to contributions. The Plan distributed the 2010 excess contributions to the applicable participants by March 15, 2011.

Notes Receivable from Participants

Notes receivable from participants represent participant loans that are recorded at their unpaid principal balance plus any accrued but unpaid interest. Interest income on notes receivable from participants is recorded when it is earned. Related fees are recorded as administrative expenses and are expensed when they are incurred. No allowance for credit losses has been recorded as of December 31, 2010 or 2009. If a participant ceases to make loan repayments and the plan administrator deems the participant loan to be a distribution, the participant loan balance is reduced and a benefit payment is recorded.

2. Summary of Significant Accounting Policies (continued)

Valuation of Investments and Income Recognition

Investments held by the Plan are stated at fair value. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (an exit price). See Note 4 for further discussion and disclosures related to fair value measurements.

The Plan invests in investment contracts through a common collective trust (Fidelity Managed Income Portfolio and Fidelity Managed Portfolio II). The Fidelity Managed Income Portfolio Trust Funds invest in fully benefit-responsive investment contracts. These funds are recorded at fair value (see Note 4); however, since these contracts are fully benefit-responsive, an adjustment is reflected in the statements of net assets available for benefits to present these investments at contract value. Contract value is the relevant measurement attributable to fully benefit-responsive investment contracts because contract value is the amount participants would receive if they were to initiate permitted transactions under the terms of the Plan. The contract value represents contributions plus earnings, less participant withdrawals and administrative expenses. The statements of net assets available for benefits present the fair value of the investment in the common collective trust as well as the adjustment from fair value to contract value for fully benefit-responsive investment contracts. The fair value of the Plan’s interest in the Fidelity Managed Income Portfolio Funds is based on information reported by the issuer of the common collective trust at year-end. The contract value of the Fidelity Managed Income Portfolio Funds represents contributions plus earnings, less participant withdrawals and administrative expenses.

The common/collective trust fund is designed to preserve principal and accumulate earnings. This fund is primarily invested in guaranteed investment contracts and synthetic investment contracts. Participant-directed redemptions have no restrictions; however, the Plan is required to provide a one year redemption notice to liquidate its entire share in the fund.

2. Summary of Significant Accounting Policies (continued)

Purchases and sales of securities are recorded on a trade-date basis. Dividends are recorded on the ex-dividend date. Net appreciation includes the Plan’s gains and losses on investments bought and sold as well as held during the year.

New Accounting Pronouncements

In January 2010, the FASB issued Accounting Standards Update 2010-06, Improving Disclosures about Fair Value Measurements, (ASU 2010-06). ASU 2010-06 amended ASC 820 to clarify certain existing fair value disclosures and require a number of additional disclosures. The guidance in ASU 2010-06 clarified that disclosures should be presented separately for each “class” of assets and liabilities measured at fair value and provided guidance on how to determine the appropriate classes of assets and liabilities to be presented. ASU 2010-06 also clarified the requirement for entities to disclose information about both the valuation techniques and inputs used in estimating Level 2 and Level 3 fair value measurements. In addition, ASU 2010-06 introduced new requirements to disclose the amounts (on a gross basis) and reasons for any significant transfers between Levels 1, 2 and 3 of the fair value hierarchy and present information regarding the purchases, sales, issuances and settlements of Level 3 assets and liabilities on a gross basis. With the exception of the requirement to present changes in Level 3 measurements on a gross basis, which is delayed until 2011, the guidance in ASU 2010-06 is effective for reporting periods beginning after December 15, 2009. Since ASU 2010-06 only affects fair value measurement disclosures, adoption of ASU 2010-06 did not affect the Plan’s net assets available for benefits or its changes in net assets available for benefits.

In September 2010, the FASB issued Accounting Standards Update 2010-25, Reporting Loans to Participants by Defined Contribution Pension Plans, (ASU 2010-25). ASU 2010-25 requires participant loans to be measured at their unpaid principal balance plus any accrued but unpaid interest and classified as notes receivable from participants. Previously loans were measured at fair value and classified as investments. ASU 2010-25 is effective for fiscal years ending after December 15, 2010 and is required to be applied retrospectively. Adoption of ASU 2010-25 did not change the value of participant loans from the amount previously reported as of December 31, 2009. Participant loans have been reclassified to notes receivable from participants as of December 31, 2009.

2. Summary of Significant Accounting Policies (continued)

In May 2011, the FASB issued Accounting Standards Update 2011-04, Amendments to Achieve Common Fair Value Measurements and Disclosure Requirements in U.S. GAAP and IFRS, (ASU 2011-04). ASU 2011-04 amended ASC 820, Fair Value Measurements and Disclosures, to converge the fair value measurement guidance in US generally accepted accounting principles (GAAP) and International Financial Reporting Standards (IFRS). Some of the amendments clarify the application of existing fair value measurement requirements, while other amendments change a particular principle in ASC 820. In addition, ASU 2011-04 requires additional fair value disclosures. The amendments are to be applied prospectively and are effective for annual periods beginning after December 15, 2011. Plan management is currently evaluating the effect that the provisions of ASU 2011-04 will have on the Plan’s financial statements.

3. Investments

During the year ended December 31, 2010, the Plan’s investments (including investments purchased and sold, as well as held, during the year) appreciated in fair value as determined by quoted market prices as follows:

4. Fair Value Measurements

The fair value hierarchy prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets and liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The three levels of the fair value hierarchy are described below:

Level 1 — Unadjusted quoted prices in active markets that are accessible to the reporting entity at the measurement date for identical assets and liabilities. The Company utilized the market approach to determine the fair value of its assets under Level 1 of the fair value hierarchy.

Level 2 — Inputs other than quoted prices in active markets for identical assets and liabilities that are observable either directly or indirectly for substantially the full term of the asset or liability. Level 2 inputs include the following:

• Quoted prices for similar assets and liabilities in active markets, as used by the Company

14

TRW Automotive
Retirement Savings Plan for Hourly Employees

Notes to Financial Statements (continued)

4. Fair Value Measurements (continued)

• Quoted prices for identical or similar assets or liabilities in markets that are not active

• Observable inputs other than quoted prices that are used in the valuation of the asset or liabilities (e.g., interest rate and yield curve quotes at commonly quoted intervals)

• Inputs that are derived principally from or corroborated by observable market data by correlation or other means

Level 3 — Unobservable inputs for the asset or liability (i.e., supported by little or no market activity). Level 3 inputs include management’s own assumption about the assumptions that market participants would use in pricing the asset or liability (including assumptions about risk). The fair values determined through Level 3 of the fair value hierarchy are derived principally from unobservable inputs provided to the Plan administrator by the trustee.

The level in the fair value hierarchy within which the fair value measurement is classified is determined based the lowest level input that is significant to the fair value measure in its entirety.

The following methods and assumptions were used to determine the fair value of investments recorded at fair value in the statements of net assets available for benefits.

Mutual funds: Valued at quoted market prices which represents net asset value (“NAV”) of shares held by the Plan at year end.

Equity securities: Valued at the quoted market price reported on the active market on which the individual securities are traded on the last business day of the plan year.

The TRW Common Stock Fund invests in TRW Automotive Holdings Corp. common stock. A small portion of the fund may also be invested in short-term reserves to accommodate daily transactions. TRW common stock is valued at the closing price on the New York Stock Exchange on the last business day of the year.

4. Fair Value Measurements (continued)

Common fund/Collective trust: Valued at the net unit value, as reported in the audited financial statements of the fund, of units held by the Plan.

5. Related-Party Transactions

Certain plan investments are units of participation in common trust funds and shares of mutual funds managed by Fidelity. Fidelity is the trustee as defined by the Plan and, therefore, these transactions qualify as party-in-interest transactions. Likewise, Kelsey-Hayes Company is the Plan sponsor and, therefore, transactions in shares of its Parent TRW Automotive Holdings Corp.’s stock would also qualify as party-in-interest transactions.

17

TRW Automotive
Retirement Savings Plan for Hourly Employees

Notes to Financial Statements (continued)

6. Risks and Uncertainties

The Plan allows for investments in various investment securities. Investment securities are exposed to various risks such as interest rate, market volatility, and credit risks. Due to the level of risk associated with certain investment securities, it is at least reasonably possible that changes in the values of investment securities will occur in the near term and that such changes could materially affect participants’ account balances and the amounts reported in the statements of net assets available for benefits.

7. Income Tax Status

The Plan has received a determination letter from the IRS dated April 25, 2002, stating that the Plan is qualified under Section 401(a) of the Internal Revenue Code (the Code) and, therefore, the related trust is exempt from taxation. Subsequent to this determination letter by the IRS, the Plan was amended. The Plan is required to operate in conformity with the Code to maintain its qualification. The Plan sponsor believes the Plan is being operated in compliance with applicable requirements of the Code and, therefore, believes that the Plan, as amended, is qualified and the related trust is tax-exempt.

Accounting principles generally accepted in the United States require plan management to evaluate uncertain tax positions taken by the Plan. The financial statement effects of a tax position are recognized when the position is more likely than not, based on the technical merits, to be sustained upon examination by the IRS. The plan administrator has analyzed the tax positions taken by the Plan, and has concluded that as of December 31, 2010, there are no uncertain positions taken or expected to be taken. The Plan has recognized no interest or penalties related to uncertain tax positions. The Plan is subject to routine audits by taxing jurisdictions; however, there are currently no audits for any tax periods in progress. The plan administrator believes it is no longer subject to income tax examinations for years prior to 2007.
