                              RESULTS BY SEGMENT

Reference is made to the information relating to the Company's industry
segments, including sales, profit before taxes and segment assets attributable
to each segment for each of the years 1997 through 1999, presented under the
note entitled "Operating Segments" in the Notes to Financial Statements on
pages 60 through 62 of the TRW 1999 Annual Report. This information is
incorporated herein by reference.

                        FOREIGN AND DOMESTIC OPERATIONS

TRW manufactures products or has principal facilities in 29 countries
throughout the world. TRW's operations outside the United States are in
Argentina, Australia, Austria, Bahrain, Brazil, Canada, China, the Czech
Republic, Egypt, France, Germany, India, Italy, Japan, Malaysia, Mexico, the
Netherlands, Oman, Poland, Portugal, Saudi Arabia, South Africa, South Korea,
Spain, Taiwan, Thailand, Turkey and the United Kingdom. TRW also exports
products manufactured by it in the United States. Such export sales accounted
for:

 . 6 percent of total sales during 1999, or $1,039 million;
 . 6 percent of total sales during 1998, or $674 million; and
 . 7 percent of total sales during 1997, or $732 million.

TRW's foreign operations are subject to the usual risks that may affect such
operations, including, among other things:

 . customary exchange controls and currency restrictions;
 . currency fluctuations and devaluations;
 . changes in local economic conditions;
 . exposure to possible expropriation or other government actions;
 . unsettled political conditions; and
 . foreign government-sponsored boycotts of the Company's products or services
  for noncommercial reasons.

Most of the identifiable assets associated with TRW's foreign operations are
located in countries where the Company believes such risks to be minimal. In
recent years, economic conditions in the Asia Pacific region and Latin
America, primarily Brazil, have had a negative impact on the Company's
operations. Future economic conditions in these regions could have continued
unfavorable effects in 2000.

Reference is made to the information relating to the dollar amounts of sales
and property, plant and equipment-net by geographic area for each of the years
1997 through 1999 presented under the note entitled "Operating Segments" in
the Notes to Financial Statements on pages 60 through 62 of the TRW 1999
Annual Report. This information is incorporated herein by reference.

                                    GENERAL

Competition

TRW encounters intense competition in substantially all segments of its
business. The Company's competitive position varies for its different products
and services. However, TRW believes that it is a significant supplier of many
of the products it manufactures and of many of the services it provides.

In the automotive businesses, competitors include independent suppliers of
parts and components as well as the Company's original equipment customers,
many of whom are integrated manufacturers who produce or could produce
substantial portions of their requirements for parts and components
internally. Some of the integrated manufacturers are becoming more aggressive
in attempting to sell components to other automotive manufacturers and have or
are considering spinning off all or a portion of their components operations
which might also make such operations more aggressive competitors. Depending
on the particular product, the number of the Company's competitors varies
significantly and many of the products have high capital requirements and
require high engineering content. In the automotive businesses and in the
Aeronautical Systems business, the principal methods of competition are:

 . price;
 . engineering excellence;
 . product quality;
 . customer service;
 . delivery time; and
 . proprietary position.

TRW competes for contracts covering a variety of U.S. Government and
commercial projects and programs in the Space & Electronics and Systems &
Information Technology businesses of its aerospace and information systems
business. Such competition is based primarily on:

 . technical ability;
 . product quality; and
 . price.

TRW's competitors for U.S. Government contracts typically are large,
technically-competent firms with substantial assets, some of which have become
considerably larger in recent years.

Customers

Sales, directly and indirectly, to the United States Government, including the
Department of Defense, the National Aeronautics & Space Administration and
other agencies, represented the following percentages of TRW's total sales:

 . 25 percent for 1999, or $4,248 million;
 . 35 percent for 1998, or $4,119 million; and
 . 33 percent for 1997, or $3,523 million.

                                       6


Sales, directly and indirectly, to the United States Government, including the
Department of Defense, the National Aeronautics & Space Administration and
other agencies, represented the following percentages of the sales of the
aerospace and information systems businesses:



                             Systems & Information
       Space & Electronics         Technology        Aeronautical Systems

1997     50%       1,881        43%       1,641       --          --


As with all companies engaged in U.S. Government contracting, TRW is subject
to certain unique business risks, including:

 . dependence on Congressional appropriations and administrative allotment of
  funds;
 . changes in U.S. Government policies that may reflect military and political
  developments;
 . time required for design and development;
 . significant changes in contract scheduling;
 . complexity of designs and the rapidity with which they become obsolete;
 . necessity of design improvements;
 . difficulty in forecasting costs and schedules when bidding on developmental
  and highly sophisticated technical work; and
 . other factors characteristic of the industry.

United States Government contracting laws also provide that the United States
Government is to do business only with responsible contractors. In this
regard, the United States Department of Defense and other federal agencies
have the authority, under certain circumstances, to suspend or debar a
contractor or organizational parts of a contractor from further U.S.
Government contracting for a certain period "to protect the Government's
interest." Such action may be taken for, among other reasons, commission of
fraud or a criminal offense in connection with a U.S. Government contract. A
suspension may also be imposed if a contractor is indicted for such matters.
In the event of any suspension or debarment, TRW's existing contracts would
continue unless terminated or canceled by the U.S. Government under applicable
contract provisions.

Other than the United States Government, TRW's largest customers (determined
by including sales to their affiliates throughout the world but excluding
sales to such customers or their affiliates that ultimately result in sales to
the United States Government) are Ford Motor Company, DaimlerChrysler AG,
General Motors Corporation and Volkswagen AG. Such sales by each of TRW's
automotive segments to Ford, DaimlerChrysler, General Motors and Volkswagen,
and their respective subsidiaries, accounted for the following percentages of
the sales of each of the automotive segments:

Backlog

The backlog of orders for TRW's operations is estimated to have been
approximately $7.2 billion at December 31, 1999 and $6.0 billion at December
31, 1998. Of those amounts, U.S. Government business, directly or indirectly,
is estimated to have accounted for approximately $5.6 billion at December 31,
1999 and $5.1 billion at December 31, 1998, substantially all of which is
related to the aerospace and information systems businesses. Reported backlog
at December 31, 1999 and 1998 does not include approximately $5.2 billion and
$5.8 billion, respectively, of negotiated and priced, but unexercised, options
of the Company's customers to purchase products and services from TRW for
defense and non-defense programs. The exercise of options is at the discretion
of the customer and, in the case of U.S. Government contracts, is dependent on
future government funding. Of the total backlog, 98 percent at December 31,
1999 and 96 percent at December 31, 1998 was attributable to the aerospace and
information systems business. Of the backlog attributable to the aerospace and
information systems business, the following percentages were attributable to
each of the segments comprising that business:

1999                 43%                               52%                                5%
1998                 47%                               53%                                --


The determination of TRW's backlog involves substantial estimating,
particularly with respect to customer requirements contracts and long-term
contracts of a cost-reimbursement or incentive nature. A substantial portion
of the variations in TRW's estimated backlog in recent years is attributable
to the timing of the award and performance of U.S. Government and certain
other contracts. Subject to various qualifications, including those set forth
herein, and assuming no terminations, cancellations or changes and completion
of orders in the normal course of business, TRW has estimated that
approximately 54 percent of the December 31, 1999 backlog will be delivered in
2000, 32 percent in 2001 and 14 percent thereafter.

United States Government contracts and related customer orders generally may
be terminated in whole or in part at the convenience of the United States
Government whenever the United States Government believes that such
termination would be in its best interest. Multi-year U.S. Government
contracts and related orders may be canceled if funds for contract performance
for any subsequent contract year become unavailable. If any of its U.S.
Government contracts were terminated or canceled under these circumstances,
TRW generally would be entitled to receive payment for work completed and
allowable termination or cancellation costs. Whether the occurrence of any
such termination or cancellation would have an adverse effect on TRW would
depend upon the particular contract and the circumstances of the termination
or cancellation.

Backlog data and comparisons as of different dates may not be reliable
indicators of either future sales or the ratio of future direct and indirect
U.S. Government sales to other sales.

Intellectual Property

TRW owns significant intellectual property, including a large number of
patents, copyrights and trade secrets, and is involved in numerous licensing
arrangements. Although TRW's intellectual property plays an important role in
maintaining TRW's competitive position in a number of the markets that it
serves, no single patent, copyright, trade secret or license, or group of
related patents, copyrights, trade secrets or licenses, is, in the opinion of
management, of such value to TRW that the business of TRW or of any industry
segment of TRW would be materially affected by the expiration or termination
thereof. TRW's general policy is to apply for patents on an ongoing basis in
the United States and appropriate other countries on its significant
patentable developments.

                                       9


TRW also views its name and mark as significant to its business as a whole. In
addition, TRW owns a number of other trade names and marks applicable to
certain of its businesses and products that it views as important to such
businesses and products.

Research and Development

Research and development costs totaled:

 . $2,168 million in 1999;
 . $2,143 million in 1998; and
 . $2,146 million in 1997.

Of these amounts, customer-funded research and development was:

 . $1,249 million in 1999;
 . $1,425 million in 1998; and
 . $1,501 million in 1997.

Company-funded research and development costs, which included research and
development for commercial products, independent research and development and
bid and proposal work related to government products and services, totaled:

 . $609 million in 1999;
 . $522 million in 1998; and
 . $461 million in 1997.

A portion of the cost incurred for independent research and development and
bid and proposal work is recoverable through overhead charged to government
contracts.

Company-funded product development costs, including engineering and field
support for new customer requirements, were:

 . $310 million in 1999;
 . $196 million in 1998; and
 . $184 million in 1997.

The 1999 and 1997 research and development costs exclude the $85 million and
$548 million charges for purchased in-process research and development
associated with the acquisitions of LucasVarity plc and BDM International,
Inc., respectively. Reference is made to the information concerning these
charges in "Management's Discussion and Analysis of the Results of Operations
and Financial Condition" under the caption "Acquisitions" on pages 33 through
35 of the TRW 1999 Annual Report and the note entitled "Acquisitions" in the
Notes to Financial Statements on pages 48 through 50 of the TRW 1999 Annual
Report. This information is incorporated herein by reference.

Employees

At December 31, 1999, TRW had approximately 122,000 employees, of whom
approximately 45,000 were employed in the United States and 48,000 were
employed in Europe.

                                      10


Raw Materials and Supplies

Materials used by TRW include or contain:

 . steel                                   . sodium azide
 . aluminum                                . glass
 . carbon and plastic                      . ceramics
  materials                               . plastic powders and
 . stainless steel                           laminations
 . pig iron                                . synthetic rubber
 . ferro-chrome                            . paper
 . brass                                   . gold, silver, nickel, zinc and
 . copper                                    copper plating materials
 . tin                                     . electronics
 . platinum                                . friction materials
 . special alloys

TRW also purchases from suppliers various types of equipment and component
parts that may include these materials. TRW's operations depend upon the
ability of its suppliers of materials, equipment and component parts to meet
performance and quality specifications and delivery schedules. In some cases,
there are only a limited number of suppliers for a material or product due to
the specialized nature of the item. Shortages of certain raw materials,
equipment and component parts have existed in the past and may exist again in
the future. TRW has taken a number of steps to protect against and to minimize
the effect of such shortages. However, any future inability of TRW to obtain
raw materials, equipment or component parts could have a material adverse
effect on the Company. TRW's operations also depend on adequate supplies of
energy. TRW has continued its programs to conserve energy used in its
operations and has available alternative sources of energy.

Environmental Regulations

Federal, state and local requirements relating to the discharge of materials
into the environment, or otherwise relating to the protection of the
environment, have had, and will continue to have, an effect on TRW and its
operations. TRW has made and continues to make expenditures for projects
relating to the environment, including pollution control devices for new and
existing facilities. TRW is conducting a number of environmental
investigations and remedial actions at current and former TRW locations to
comply with various federal, state and local laws and, along with other
companies, has been named a potentially responsible party for certain waste
management sites. Each of these matters is subject to various uncertainties,
and some of these matters may be resolved unfavorably to TRW.

A reserve estimate reflecting cost ranges is established using standard
engineering cost estimating techniques for each matter for which sufficient
information is available. In the determination of cost ranges, the
professional judgment of TRW's environmental engineers, in consultation with
outside environmental specialists, when necessary, is considered. At multi-
party sites, the reserve estimate also reflects the expected allocation of
total project costs among the various potentially responsible parties. At
December 31, 1999, TRW had reserves for environmental matters of $136 million,
including $13 million of additional expense recorded during the year and $66
million of reserves relating to the LucasVarity acquisition. TRW aggressively
pursues reimbursement for environmental costs from its insurance carriers.
Insurance recoveries are recorded as a reduction of environmental costs when
fixed and determinable.

TRW does not believe that compliance with environmental protection laws and
regulations will have a material effect upon its capital expenditures or
competitive position, and TRW's capital expenditures for environmental control
facilities during 2000 and 2001 are not expected to be material to the
Company. TRW believes that any liability that may result from the resolution
of environmental matters for which sufficient information is available to
support cost estimates will not have a material adverse effect on the
Company's earnings. However, TRW cannot predict the effect on the Company's
earnings of expenditures for aspects of certain matters for which

                                      11


there is insufficient information. See also "Legal Proceedings" on page 15 of
this Annual Report on Form 10-K. In addition, TRW cannot predict the effect on
the Company's earnings of compliance with environmental laws and regulations
with respect to currently unknown environmental matters or the possible effect
on the Company's earnings of compliance with environmental requirements
imposed in the future.

Capital Expenditures -- Property, Plant and Equipment

During the five years ended December 31, 1999, TRW's capital expenditures and

Of total capital expenditures, 42 percent in 1999 and 52 percent in 1998 were
invested in the United States.

ITEM 2. PROPERTIES.

TRW's operations include numerous manufacturing, research and development and
warehousing facilities. TRW owns or leases principal facilities located in 25
states plus the District of Columbia in the United States and in 28 other
countries. Approximately 46 percent of the principal domestic facilities are
used by the automotive businesses, 52 percent are used by the aerospace and
information systems businesses and 2 percent are used at the corporate level.
The automotive businesses use a substantial majority of the foreign
facilities.

Of the total number of principal facilities operated by TRW, approximately 56
percent of such facilities are owned, 35 percent are leased, 5 percent are
held by joint ventures in which TRW has a majority interest and 4 percent are
operated on property owned directly or indirectly by the U.S. Government. The
Company owns its world headquarters in Lyndhurst, Ohio as well as the
headquarters for its Space & Electronics segment in Redondo Beach, California,
its Aeronautical Systems segment in Birmingham, England and its Occupant
Safety Systems segment in Washington, Michigan.

                                      12


The Company also owns, leases or operates on government-owned property,
certain smaller research and development properties and administrative,
marketing, sales and office facilities throughout the United States and in
various parts of the world.

A summary of TRW's principal facilities, by segment, type of facility and
geographic region, is set forth in the following tables. The multi-purpose
facilities are listed under each category for which a portion of the square
footage of that facility is used. For example, TRW's headquarters for its
Space & Electronics segment in Redondo Beach, California is categorized as a
manufacturing facility, a research and development facility and as office
space, as significant portions of its square footage are utilized for each of
these purposes. Additionally, where more than one segment utilizes a single
facility, that facility will be categorized by the purposes for which it is
used by each such segment. For example, TRW's Redondo Beach facility serves
not only as the headquarters and a manufacturing and research and development
facility for its Space & Electronics business but is also utilized by its
Systems & Information Technology business as both office space and a research
and development facility. As such, this facility will appear in the following
tables under both Space & Electronics and Systems & Information Technology.

In addition to the facilities set forth in the foregoing tables, TRW also
maintains approximately eleven facilities that it utilizes as office space at
the corporate level. Two of such facilities are located in North America, one
in Europe and the remaining eight facilities are located in the Asia Pacific
region.

In the opinion of management, the Company's facilities are generally well
maintained and are suitable and adequate for their intended use.

ITEM 3. LEGAL PROCEEDINGS.

During 1996, the United States Department of Justice, or the DOJ, advised the
Company that it had been named as a defendant in two lawsuits brought by
Richard D. Bagley, a former employee of the Company's former Space &
Technology Group, and originally filed under seal in 1994 and 1995,
respectively, in the United States District Court for the Central District of
California under the qui tam provisions of the civil False Claims Act. The Act
permits an individual to bring suit in the name of the United States and share
in any recovery. The allegations in the lawsuits relate to the classification
of costs incurred by the Company that were charged to certain of its federal
contracts. Under the law, the government must investigate the allegations and
determine whether it wishes to intervene and take responsibility for the
lawsuits. On February 13, 1998, the DOJ intervened in the litigation. On
February 19, 1998 and March 4, 1998, Bagley filed amended complaints in the
Central District of California that realleged certain of the claims included
in the 1994 and 1995 lawsuits and omitted the remainder. The amended
complaints allege that the United States has incurred substantial damages and
that the Company should be ordered to cease and desist from violations of the
civil False Claims Act and is liable for treble damages, penalties, costs,
including attorneys' fees, and such other relief as deemed proper by the
court. On March 17, 1998, the DOJ filed its complaint against the Company upon
intervention in the 1994 lawsuit, which set forth a limited number of the
allegations in the 1994 lawsuit and certain additional allegations. The DOJ
elected not to pursue the other claims in the 1994 lawsuit or the claims in
the 1995 lawsuit. The DOJ's complaint alleges that the Company is liable for
treble damages, penalties, interest, costs and "other proper relief." On March
18, 1998, Bagley withdrew the first amended complaint in the 1994 lawsuit at
the request of the DOJ. On May 18, 1998, the Company filed answers to Bagley's
first amended complaint in the 1995 lawsuit and to the DOJ's complaint,
denying all substantive allegations contained therein. At the same time, the
Company filed counterclaims against both Bagley and the federal government. On
July 20, 1998, both Bagley and the DOJ filed motions seeking to dismiss the
Company's counterclaims. On November 23, 1998 (entered as an Order on January
21, 1999), the court dismissed certain counterclaims asserted against Bagley
and the federal government and took under advisement Bagley's motion to
dismiss certain other counterclaims. On March 15, 1999, the DOJ was granted
leave to file a First Amended Complaint, which adds certain allegations
concerning the Company's subcontracts. On August 6, 1999, the Government filed
its Second Amended Complaint, which incorporated vouchers, progress payment
requests, and invoices submitted by TRW to higher tier Government contractors
among the class of allegedly false claims challenged by the Government. On
September 29, 1999, Bagley filed his Second Amended Complaint, which
incorporated subcontracts performed by TRW for higher tier Government
contractors among the class of contracts under which allegedly false claims
were presented, and added allegations relating to certain of Bagley's pre-
existing claims. The Company cannot presently predict the outcome of these
lawsuits, although management believes that their ultimate resolution will not
have a material effect on the Company's financial condition or results of
operations.

On December 15, 1987, the Commissioner of the Indiana Department of
Environmental Management issued an Order to TRW and several other respondents
relating to alleged contamination of the public water supply in Shelbyville,
Indiana by, among other sources, two closed facilities that were formerly
operated by TRW's Connectors Division. The Order requires the respondents to
fund the relocation of the main well field for Shelbyville to a location that
can provide a safe source of potable water and to perform a remedial
investigation of the source and extent of contamination within a one-mile
radius of the well field. The Order also requires the respondents to pay civil
penalties of $25,000 per day for violations of law that allegedly occurred
prior to issuance of the Order. TRW has filed a petition for review of the
Order. The Order is not expected to have a material effect on the Company's
financial position.

                                      15


TRW Vehicle Safety Systems Inc., a wholly-owned subsidiary of the Company,
reported to the Arizona Department of Environmental Quality, or ADEQ, in 1997,
potential violations of the Arizona hazardous waste law at its Queen Creek,
Arizona facility for the possible failure to properly label and dispose of
wastewater that might be classified as hazardous waste. ADEQ, the United
States Environmental Protection Agency, the United States Department of
Justice and the Arizona State Attorney General are conducting civil and
criminal investigations into these potential violations and the Company is
cooperating with these investigations. If proceedings were to be initiated
against the Company with respect to such matters, the Company could be liable
for penalties and fines and other relief. The Company is currently engaged in
settlement discussions with state and federal officials. The Company is not
able to predict the outcome of these discussions at this time.

REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS

Shareholders and Directors, TRW Inc.

We have audited the consolidated financial statements of TRW Inc. and
subsidiaries listed in Item 14(a)(1) of the Annual Report on Form 10-K of TRW
Inc. for the year ended December 31, 1999. These financial statements are the
responsibility of the Company's management. Our responsibility is to express
an opinion on these financial statements based on our audits.

We conducted our audits in accordance with auditing standards generally
accepted in the 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. An audit includes examining, on
a test basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used
and significant estimates made by management, as well as 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 consolidated financial position of TRW Inc. and
subsidiaries at December 31, 1999 and 1998, and the consolidated results of
their operations and their cash flows for each of the three years in the
period ended December 31, 1999, in conformity with accounting principles
generally accepted in the United States.
