RECENT DEVELOPMENTS

Controlled Company Status

Prior to the completion of this offering, our company availed itself of the “controlled company” exemption under the NYSE corporate governance rules that eliminates the requirements that our board of directors be composed of a majority of independent directors and that our compensation and nominating and corporate governance committees be composed entirely of “independent” directors within the meaning of the NYSE listing requirements. Upon completion of this offering, we will cease to be a “controlled company” for purposes of the NYSE corporate governance rules. Accordingly, in accordance with the NYSE rules, we will phase in compliance with the NYSE independence requirements, including the requirements that our board of directors consist of a majority of independent directors and that our nominating and corporate governance committee and our compensation committee consist entirely of independent directors. Under the NYSE listing requirements, upon the closing of this offering, we will be required to have at least one independent member on each of the nominating and corporate governance committee and the compensation committee. Within 90 days of the closing of this offering, each of the nominating and corporate governance committee and the compensation committee must consist of a majority of independent directors, and within twelve months of the closing of this offering, the members of these committees must all be independent within the meaning of the NYSE listing requirements. In addition, within twelve months of the closing of this offering, the majority of our board of directors must be independent within the meaning of the NYSE listing requirements. Because five of the nine members of our current board of directors qualify as independent under the NYSE rules, we are in compliance with the NYSE listing requirement regarding board independence. We intend to comply with the NYSE listing requirements regarding committee independence.

RISK FACTORS

We urge you to carefully consider the risks described beginning on page 4 of the accompanying prospectus, as well as the other information we have provided in this prospectus supplement, the accompanying prospectus and the documents we incorporate by reference, before reaching a decision regarding an investment in our common stock.

USE OF PROCEEDS

All of the shares of common stock offered by this prospectus supplement will be sold by the selling stockholders. We will not receive any of the proceeds from the sale of shares by the selling stockholders.

We do not currently, nor do we plan to, pay any cash dividends on our common stock, and instead intend to retain any earnings for debt repayment, future operations and expansion. The amounts available to us to pay cash dividends are restricted by our debt agreements. Under TRW Automotive Inc.’s senior credit facilities, we have a limited ability to pay dividends on our common stock, which is dependent on maintaining a certain leverage ratio, and may be increased by a portion of our cumulative consolidated net income after January 1, 2005. The indentures governing TRW Automotive Inc.’s senior notes also limit our ability to pay dividends. Any decision to declare and pay dividends in the future will be made at the discretion of our board of directors and will depend on, among other things, our results of operations, cash requirements, financial condition, contractual restrictions and other factors that our board of directors may deem relevant.

SELLING STOCKHOLDERS

The following table sets forth information regarding the beneficial ownership of our common stock as of May 24, 2007, and as adjusted to reflect the sale of the shares of common stock offered in this offering, for each stockholder selling shares in this offering.

With respect to the selling stockholders, all information contained in the table below is based upon the information provided to us by the selling stockholders, and we have not independently verified this information.

The number of shares beneficially owned by each stockholder is determined under rules promulgated by the Securities and Exchange Commission. The information is not necessarily indicative of beneficial ownership for any other purpose. Under these rules, beneficial ownership includes any shares as to which the individual or entity has sole or shared voting or investment power and any shares as to which the individual or entity has the right to acquire beneficial ownership within 60 days after May 24, 2007 through the exercise of any stock option or other right. The applicable percentage of ownership for each stockholder is based on 99,299,173 shares of common stock outstanding as of May 24, 2007, together with the shares underlying the applicable options for that stockholder. The inclusion in the following table of those shares, however, does not constitute an admission that the named stockholder is a direct or indirect beneficial owner of such shares.

A “non-U.S. holder” means a person (other than a partnership) that is not for United States federal income tax purposes any of the following:

•  an individual citizen or resident of the United States;

•  a corporation (or any other entity treated as a corporation for United States federal income tax purposes) created or organized in or under the laws of the United States, any state thereof or the District of Columbia;

•  an estate the income of which is subject to United States federal income taxation regardless of its source; or

•  a trust if it (1) is subject to the primary supervision of a court within the United States and one or more United States persons have the authority to control all substantial decisions of the trust or (2) has a valid election in effect under applicable United States Treasury regulations to be treated as a United States person.

This summary is based upon provisions of the Internal Revenue Code of 1986, as amended (the “Code”), and regulations, rulings and judicial decisions as of the date hereof. Those authorities may be changed, perhaps retroactively, so as to result in United States federal income and estate tax consequences different from those summarized below. This summary does not address all aspects of United States federal income and estate taxes and does not deal with foreign, state, local or other tax considerations that may be relevant to non-U.S. holders in light of their personal circumstances. In addition, it does not represent a detailed description of the United States federal income tax consequences applicable to you if you are subject to special treatment under the United States federal income tax laws (including if you are a United States expatriate, “controlled foreign corporation,” “passive foreign investment company” or a partnership or other pass-through entity for United States federal income tax purposes). We cannot assure you that a change in law will not alter significantly the tax considerations that we describe in this summary.

S-9

If a partnership holds our common stock, the tax treatment of a partner will generally depend upon the status of the partner and the activities of the partnership. If you are a partner of a partnership holding our common stock, you should consult your tax advisors.

If you are considering the purchase of our common stock, you should consult your own tax advisors concerning the particular United States federal income and estate tax consequences to you of the ownership of the common stock, as well as the consequences to you arising under the laws of any other taxing jurisdiction.

Dividends

Dividends paid to a non-U.S. holder of our common stock generally will be subject to withholding of United States federal income tax at a 30% rate or such lower rate as may be specified by an applicable income tax treaty. However, dividends that are effectively connected with the conduct of a trade or business by the non-U.S. holder within the United States (and, if required by an applicable tax treaty, are attributable to a United States permanent establishment of the non-U.S. holder) are not subject to the withholding tax, provided certain certification and disclosure requirements are satisfied. Instead, such dividends are subject to United States federal income tax on a net income basis in the same manner as if the non-U.S. holder were a United States person as defined under the Code. Any such effectively connected dividends received by a foreign corporation may be subject to an additional “branch profits tax” at a 30% rate or such lower rate as may be specified by an applicable income tax treaty.

A non-U.S. holder of our common stock who wishes to claim the benefit of an applicable treaty rate and avoid backup withholding, as discussed below, for dividends will be required (a) to complete Internal Revenue Service Form W-8BEN (or other applicable form) and certify under penalty of perjury that such holder is not a United States person as defined under the Code and is eligible for treaty benefits or (b) if our common stock is held through certain foreign intermediaries, to satisfy the relevant certification requirements of applicable United States Treasury regulations. Special certification and other requirements apply to certain non-U.S. holders that are pass-through entities rather than corporations or individuals.

A non-U.S. holder of our common stock eligible for a reduced rate of United States withholding tax pursuant to an income tax treaty may obtain a refund of any excess amounts withheld by filing an appropriate claim for refund with the Internal Revenue Service.

Gain on Disposition of Common Stock

Any gain realized on the disposition of our common stock generally will not be subject to United States federal income tax unless:

•  the gain is effectively connected with a trade or business of the non-U.S. holder in the United States (and, if required by an applicable income tax treaty, is attributable to a United States permanent establishment of the non-U.S. holder);

•  the non-U.S. holder is an individual who is present in the United States for 183 days or more in the taxable year of that disposition, and certain other conditions are met; or

•  we are or have been a “United States real property holding corporation” for United States federal income tax purposes.

An individual non-U.S. holder described in the first bullet point immediately above will be subject to tax on the net gain derived from the sale under regular graduated United States federal income tax rates. An individual non-U.S. holder described in the second bullet point immediately above will be subject to a flat 30% tax on the gain derived from the sale, which may be offset by United States source capital losses, even though the individual is not considered a resident of the United States. If a non-U.S. holder that is a foreign corporation falls under the first bullet point immediately above, it will be subject to tax on its net gain in the same manner as if it were a United States person as defined under the Code and, in addition, may be subject to the branch profits tax equal to 30% of its effectively connected earnings and profits or at such lower rate as may be specified by an applicable income tax treaty.

S-10

We believe we are not and do not anticipate becoming a “United States real property holding corporation” for United States federal income tax purposes.

Federal Estate Tax

Common stock held by an individual non-U.S. holder at the time of death will be included in such holder’s gross estate for United States federal estate tax purposes, unless an applicable estate tax treaty provides otherwise.

Information Reporting and Backup Withholding

We must report annually to the Internal Revenue Service and to each non-U.S. holder the amount of dividends paid to such holder and the tax withheld with respect to such dividends, regardless of whether withholding was required. Copies of the information returns reporting such dividends and withholding may also be made available to the tax authorities in the country in which the non-U.S. holder resides under the provisions of an applicable income tax treaty.

A non-U.S. holder will be subject to backup withholding for dividends paid to such holder unless such holder certifies under penalty of perjury that it is a non-U.S. holder (and the payor does not have actual knowledge or reason to know that such holder is a United States person as defined under the Code), or such holder otherwise establishes an exemption.

Information reporting and, depending on the circumstances, backup withholding will apply to the proceeds of a sale of our common stock within the United States or conducted through certain United States-related financial intermediaries, unless the beneficial owner certifies under penalty of perjury that it is a non-U.S. holder (and the payor does not have actual knowledge or reason to know that the beneficial owner is a United States person as defined under the Code), or such owner otherwise establishes an exemption.

Any amounts withheld under the backup withholding rules may be allowed as a refund or a credit against a non-U.S. holder’s United States federal income tax liability provided the required information is furnished to the Internal Revenue Service.

VALIDITY OF THE SHARES

The validity of the shares of common stock offered hereby will be passed upon for us by Simpson Thacher & Bartlett LLP, New York, New York and for the underwriters by Cravath, Swaine & Moore LLP, New York, New York. An investment vehicle comprised of selected partners of Simpson Thacher & Bartlett LLP, members of their families, related parties and others own an interest representing less than 1% of the capital commitments of funds controlled by The Blackstone Group L.P.

Risk Factors

Loss of market share by the Big Three may adversely affect our results in the future.

Recently, Ford Motor Company, General Motors and the Chrysler unit of DaimlerChrysler AG (the “Big Three”) have been losing market share for vehicle sales in North America and Europe. At the same time, Asian vehicle manufacturers have increased their share in such markets. Although we do have business with the Asian vehicle manufacturers, our customer base is more heavily weighted towards the Big Three. In addition, declining market share and inherent structural issues with the Big Three have led to recent announcements of an unprecedented level of production cuts. In order to address market share declines, reduced production levels, negative industry trends and other structural issues specific to their companies (such as significant overcapacity and pension and healthcare costs), the Big Three and certain of our other customers are undergoing various forms of restructuring initiatives (including, in certain cases, reorganization under bankruptcy laws). In the case of Ford, North American restructuring actions have been accelerated and expanded during the third quarter of 2006 to remove additional production capacity over the next several years. Such substantial restructuring initiatives undertaken by our major customers will have a ripple effect throughout our industry and may have a severe impact on our business and our common suppliers.

Escalating pricing pressures from our customers may adversely affect our business.

Pricing pressure in the automotive supply industry has been substantial and is likely to continue. Virtually all vehicle manufacturers seek price reductions in both the initial bidding process and during the term of the contract. Price reductions have impacted our sales and profit margins and are expected to do so in the future. If we are not able to offset continued price reductions through improved operating efficiencies and reduced expenditures, those price reductions may have a material adverse effect on our results of operations.

Commodity inflationary pressures may adversely affect our profitability and the viability of our Tier 2 and Tier 3 supply base.

The cost of some of the commodities we use in our business has increased. Ferrous metals, resins, yarns, energy costs and other petroleum-based products have become more expensive. This has put significant operational and financial burdens on us and our suppliers. It is usually difficult to pass increased prices for manufactured components and raw materials through to our customers in the form of price increases. Furthermore, our suppliers may not be able to handle the commodity cost increases and still perform as we expect. In fact, we have seen the number of bankruptcies or insolvencies increase due in part to the recent inflationary pressures. The unstable condition of some of our suppliers or their failure to perform has led to certain delivery delays and production issues and has negatively impacted certain of our businesses in the third quarter of 2006. The overall condition of our supply base may possibly lead to further delivery delays, production issues or delivery of non-conforming products by our suppliers in the future.

Our business would be materially and adversely affected if we lost any of our largest customers.

For the quarter ended September 29, 2006, sales to our four largest customers on a worldwide basis were approximately 55% of our total sales. Although business with each customer is typically split among numerous contracts, if we lost a major customer or that customer significantly reduced its purchases of our products, there could be a material adverse affect on our business, results of operations and financial condition.

Work stoppages or other labor issues at the facilities of our customers or other suppliers could adversely affect our operations.

The turbulence in the automotive industry and actions taken by our customers and other suppliers to address negative industry trends may have the side effect of exacerbating labor relations problems at those companies. If any of our customers experience a material work stoppage, that customer may halt or limit the purchase of our products. Similarly, a work stoppage at another supplier could interrupt production at our customer which would have the

4

same effect. This could cause us to shut down production facilities relating to those products, which could have a material adverse effect on our business, results of operations and financial condition.

Our variable rate indebtedness exposes us to interest rate risk, which could cause our debt costs to increase significantly.

A majority of our borrowings, including borrowings under TRW Automotive Inc.’s senior credit facilities, are at variable rates of interest and expose us to interest rate risk. As of September 29, 2006, approximately 63% of our total debt was at variable interest rates. In view of the recent climate of rising interest rates, the amount we are required to pay on our variable rate indebtedness has increased and may increase further even though the amount borrowed remained the same.

Strengthening of the U.S. dollar could materially impact our results of operations.

In 2005, over half of our sales originated outside the United States. We translate sales and other results denominated in foreign currencies into U.S. dollars for our consolidated financial statements. This translation is based on average exchange rates during a reporting period. During times of a strengthening U. S. dollar, our reported international sales and earnings would be reduced because foreign currencies may translate into fewer U.S. dollars.

Our available cash and access to additional capital may be limited by our substantial debt.

We have a significant amount of debt. This amount of debt may limit our ability to obtain additional financing for our business. It may also limit our ability to adjust to changing market conditions because of the covenants and restrictions in the debt. In addition, we have to devote substantial cash to the payment of interest and principal on the debt, which means that cash may not be used for other of our business needs. We may be more vulnerable to an economic or industry downturn than a company with less debt.

The cyclicality of automotive production and sales could adversely affect our business.

Automotive production and sales are highly cyclical and depend on general economic conditions, consumer spending and preferences, labor relations issues, regulatory requirements, trade agreements and other factors. The volume of automotive production has fluctuated from year to year, which leads to fluctuations in the demand for our products. Any significant economic decline that results in a reduction in automotive production and sales by vehicle manufacturers could have a material adverse effect on our results of operations.

We may incur material losses and costs as a result of product liability, warranty and recall claims that may be brought against us.

In our business, we are exposed to product liability and warranty claims. In addition, we may be required to participate in a recall of a product. Vehicle manufacturers are increasingly looking to their suppliers for contribution when faced with product liability, warranty and recall claims. In addition, vehicle manufacturers have experienced increasing recall campaigns in recent years. Product liability, warranty and recall costs may have a material adverse effect on our financial condition.

Our pension and other post-retirement benefits expense and the funding requirements of our pension plans could materially increase.

Most of our employees participate in defined benefit pension plans or retirement/termination indemnity plans. The rate at which we are required to fund these plans depends on certain assumptions which depend in part on market conditions. As market conditions change, these assumptions may change, resulting in a decline in pension asset values. Future declines could materially increase the necessary funding status of our plans, and may require us to contribute more to these plans earlier than we anticipated. Also, this could significantly increase our pension expenses and reduce our profitability.

5

We also sponsor other post-retirement benefit (“OPEB”) plans for most of our U.S. and some of our non-U.S. employees. We fund our OPEB obligations on a pay-as-you-go basis and have no plan assets. If health care costs in the future increase more than we anticipated, our actuarially determined liability and our related OPEB expense could increase along with future cash outlays.

We are subject to risks associated with our non-U.S. operations.

We have significant manufacturing operations outside the United States, including joint ventures and other alliances. International operations involve risks, including exchange controls and currency restrictions, currency fluctuations and devaluations, changes in local economic conditions, changes in laws and regulations and unsettled political conditions and possible terrorist attacks against United States’ or other interests.

These and other factors may have a material adverse effect on our international operations or on our business, results of operations and financial condition.

We have recorded a significant amount of goodwill and other identifiable intangible assets, which may become impaired in the future.

We have recorded a significant amount of goodwill and other identifiable intangible assets, including customer relationships, trademarks and developed technologies. Goodwill and other net identifiable intangible assets were approximately $3.063 billion as of September 29, 2006, or 30% of our total assets. Goodwill, which represents the excess of cost over the fair value of the net assets of the businesses acquired, was approximately $2.317 billion as of September 29, 2006, or 23% of our total assets.

Impairment of goodwill and other identifiable intangible assets may result from, among other things, deterioration in our performance, adverse market conditions, adverse changes in applicable laws or regulations, including changes that restrict the activities of or affect the products sold by our business, and a variety of other factors. The amount of any quantified impairment must be expensed immediately as a charge that is included in operating income. We are subject to financial statement risk in the event that goodwill or other identifiable intangible assets become impaired.

Our expected annual effective tax rate could be volatile and materially change as a result of changes in mix of earnings and other factors.

The overall effective tax rate is equal to our total tax expense as a percentage of our total earnings before tax. However, tax expense and benefits are not recognized on a global basis but rather on a jurisdictional or legal entity basis. Losses in certain jurisdictions provide no current financial statement tax benefit. In addition, certain taxing jurisdictions have statutory rates greater than or less than the United States. As a result, changes in the mix of projected earnings between jurisdictions, among other factors, could have a significant impact on our overall effective tax rate.

We may be adversely affected by environmental and safety regulations or concerns.

Laws and regulations governing environmental and occupational safety and health are complicated, change frequently and have tended to become stricter over time. As a manufacturing company, we are subject to these laws and regulations both inside and outside the United States. We may not be in complete compliance with such laws and regulations at all times. Our costs or liabilities relating to them may be more than the amount we have reserved, which difference may be material. We have spent money to comply with environmental requirements. In addition, certain of our subsidiaries are subject to pending litigation raising various environmental and human health and safety claims, including certain asbestos-related claims. While our annual costs to defend and settle these claims in the past have not been material, we cannot assure you that this will remain so in the future.

6

Developments or assertions by or against us relating to intellectual property rights could materially impact our business.

We own significant intellectual property, including a large number of patents, trademarks, copyrights and trade secrets, and are involved in numerous licensing arrangements. Our intellectual property plays an important role in maintaining our competitive position in a number of the markets that we serve. Developments or assertions by or against us relating to intellectual property rights could materially impact our business.

Because Blackstone controls us, the influence of our public shareholders over significant corporate actions will be limited, and conflicts of interest between Blackstone and us or our public shareholders could arise in the future.

Currently an affiliate of The Blackstone Group L.P. (“Blackstone”) beneficially owns approximately 56% of our outstanding shares of common stock. As a result, Blackstone has the power to control all matters submitted to our stockholders, elect our directors and exercise control over our decisions to enter into any corporate transaction and has the ability to prevent any transaction that requires the approval of stockholders regardless of whether or not other stockholders believe that any such transactions are in their own best interests.

World health issues may interrupt our business.

We are subject to risks relating to public health conditions, including an actual or potential avian flu or other pandemic in a country where we source or sell our products. Any such outbreak in or outside of the United States could lead to significant disruptions of our business.

Use of Proceeds

In the case of a sale of securities by us, the use of proceeds will be specified in the applicable prospectus supplement. In the case of a sale of securities by any selling stockholder, we will not receive any of the proceeds from such sale.

The common stock may be sold on any national securities exchange on which the common stock may be listed at the time of sale, in the over-the-counter market or in transactions otherwise than on such exchanges or in the over-the-counter market or in transactions that include special offerings and exchange distributions pursuant to and in accordance with the rules of such exchanges.

We or the selling stockholders may enter into derivative transactions or forward sale agreements on shares of common stock with third parties. In such event, we or the selling stockholders may pledge the shares underlying such transactions to the counterparties under such agreements, to secure our or the selling stockholders’ delivery obligation. The counterparties or third parties may borrow shares of common stock from us, the selling stockholders or third parties and sell such shares in a public offering. This prospectus may be delivered in conjunction with such sales. Upon settlement of such transactions, we or the selling stockholders may deliver shares of common stock to the counterparties that, in turn, the counterparties may deliver to us, the selling stockholders or third parties, as the case may be, to close out the open borrowings of common stock. The counterparty in such transactions will be an underwriter and will be identified in the applicable prospectus supplement.

A prospectus supplement may be used for resales from time to time by any holder of our securities that may acquire such shares of common stock upon an in-kind distribution by any existing security holder of all or a portion of such existing security holder’s shares to its limited and general partners. Such selling stockholders may include direct and indirect transferees, pledgees. donees and successors of the selling stockholders. Further, a prospectus supplement may be used in connection with sales or resales by any general partner of a selling stockholder in connection with sales by such general partner for cash or subsequent transfers by such general partner to its limited partners of their ratable portion of the shares then owned by such general partner, together with resales of such shares by such limited partners.

Underwriters or agents may purchase and sell the securities in the open market. These transactions may include over-allotment, stabilizing transactions, syndicate covering transactions and penalty bids. Over-allotment involves sales in excess of the offering size, which creates a short position. Stabilizing transactions consist of bids or purchases for the purpose of preventing or retarding a decline in the market price of the securities and are permitted so long as the stabilizing bids do not exceed a specified maximum. Syndicate covering transactions involve the placing of any bid on behalf of the underwriting syndicate or the effecting of any purchase to reduce a short position created in connection with the offering. The underwriters or agents also may impose a penalty bid, which permits them to reclaim selling concessions allowed to syndicate activities that may stabilize, maintain or otherwise affect the market price of the securities, which may be higher than the price that might otherwise prevail in the open market. These activities, if begun, may be discontinued at any time. These transactions may be effected on any exchange on which the securities are traded, in the over-the-counter market or otherwise.

Our common stock is listed on the New York Stock Exchange under the symbol “TRW”.

The specific terms of the lock-up provisions in respect of any given offering will be described in the applicable prospectus supplement.
