Products

Semiconductor Test Solutions

   Semiconductor Test Systems produced by Teradyne are used by electronic
component manufacturers in the design and testing of a wide variety of
semiconductor devices, including logic, memory, mixed signal, and "system on a
chip" integrated circuits. Semiconductor Test Systems are sold to semiconductor
manufacturers, often referred to as "Integrated Device Manufacturers," and
subcontractors to the semiconductor industry who may perform design and/or
manufacturing functions, often referred to as "Fabless/Subcons." Customers use
Teradyne's Semiconductor Test Systems to:

    .  measure product performance;
    .  control and improve product quality;
    .  improve device design;
    .  reduce time to market;
    .  enhance manufacturability;

                                      2



    .  minimize labor costs; and
    .  increase production yields,

with the overall benefit of comprehensively testing advanced performance
devices while reducing total costs associated with testing.

   The semiconductor test market is comprised of two sub-markets. The first
sub-market is memory device testing, which includes the testing of dynamic
random access memory ("DRAMs") of all types (synchronous, double data rate
("DDR") and Rambus(TM)), static random access memory ("SRAMs") and flash
memory. The second sub-market is non-memory device testing, which includes the
testing of analog, mixed-signal and system-on-a-chip devices, high performance
logic devices and logic devices produced in high volumes.

   Teradyne products within the Semiconductor Test Systems market include:

Memory Test Solutions

   Reducing cost of test is especially crucial in the highly price sensitive
memory device market. Wafer probing, or contacting the silicon die to test it
prior to packaging, has become an increasingly popular means to increase yield
and reduce test costs. Teradyne's Probe-One memory test system delivers one of
the shortest possible test times per wafer and one of the lowest test costs.
The Probe-One's Flex-Die(TM) architecture delivers the ability to test multiple
memory arrays in parallel, further increasing test productivity and reducing
test cost. The Probe-One was introduced in 2001. The testing of packaged memory
devices remains an important market, as well. Teradyne's J996 memory test
system provides high throughput package test solutions for next generation
memory devices. The J996 has the accuracy and waveform fidelity to test 250
MegaHertz devices, and is able to test sixty-four 16 Input/Output devices in
parallel with a minimal amount of floor space. Teradyne's Aires test system is
designed for newest-generation memory devices such as DDR, Direct Rambus(TM)
DRAMs and fast SSRAMs. Accurately delivering the high speed, complex patterns
required for characterization of these emerging devices, Aires' FlexSystem
architecture combines full function memory and logic pattern generators with a
per-pin timing system.

System-on-a-Chip / Mixed Signal / Analog Test Solutions

   Semiconductor devices that employ both analog and digital circuits are
referred to as "mixed-signal devices." Recent mixed-signal devices called
"system on chip," such as those employed in consumer electronics and wireless
communication products, include significantly increased functionality compared
to earlier mixed-signal devices. The introduction of Teradyne's Catalyst test
systems in 1996 began the system-on-a-chip test revolution, providing a single,
integrated test environment for system-on-a-chip testing. Teradyne's Catalyst
Tiger test system, introduced in 2000, extends component and functional test
capability to very high device operating speeds. Catalyst and Catalyst Tiger
test systems reduce time to market and cost to test across the customer
spectrum, from Integrated Device Manufacturers to Fabless/Subcons. With a
market share nearly double its nearest competitor, a majority of people who use
a personal computer, surf the Internet, or watch a DVD, are using a product
whose semiconductor device was tested with the Catalyst test systems. Teradyne
also estimates that 75% of the world's cell phones include devices tested on
Teradyne system-on-a-chip / mixed-signal test systems. As of December 31, 2001,
more than 1,000 Catalyst test systems have been shipped to customers worldwide.
Teradyne's predecessor to the Catalyst test systems, the A5 test systems of
advanced mixed-signal test systems has a worldwide installed base of more than
1,000 systems and covers a wide range of device applications, including
automotive and telecommunications.

High Performance Test Solutions

   High performance devices such as microprocessors require high performance
automatic test equipment for both functional ("Does it function properly?") and
structural ("Is it constructed properly?") testing. Very Large Scale
Integration ("VLSI") test systems offer solutions for the broadest range of
high performance devices used in today's electronics and Internet products,
such as personal computers and video game consoles, Internet routers and
switches, and network servers. Almost every type of high-end microprocessor,
integrated processor,

                                      3



and graphic device in the world today is tested on a Teradyne high performance
logic test system. Teradyne's J973EP is one of the only VLSI test systems
designed for the wide range of testing capability needed for structural to
functional testing in a single test system. This product's flexible
configuration provides the ability to switch between functional and structural
test in real time, minimizing test cost by matching test performance to device
test requirements only when needed. The J973EP expands the performance curve on
accuracy, precision device power, and differential bus testing.

High Volume Device Test Solutions

   Devices tested in high volume, such as microcontrollers, are at the heart of
almost every consumer electronics product, from small appliances to automotive
engine controllers. Produced in enormous quantities where every penny matters,
delivering the lowest cost of test at very high production throughput rates is
essential. Teradyne's Integra test systems combine compact packaging, high
performance, and ease of use into a system designed to meet the high volume /
low cost requirements of microcontroller production test. Increasing the level
of integration in the system is key to reducing system cost and size. Teradyne
is the first automatic test equipment vendor to combine four channels of
automatic test equipment timing functionality into a single custom
semiconductor device. Teradyne's design team created an innovative technique
that enabled integration of a full 64 channels of test capability onto a single
printed circuit board. This design approach eliminated the mainframe and
interconnection cabling resulting in a complete test system housed in a compact
test head-only configuration. Its "zero footprint" design reduces the total
cost of ownership and allows for more efficient use of production floor space.
Teradyne's Integra test systems include the J750 and J750k. Using the same
compact, low cost architecture Teradyne's IP750 CCD Image Sensor test system
enjoys the world's largest shipment volume and installed base in the image
sensor device test market, driven by the burgeoning popularity of digital
cameras and other imaging products.

Connection Systems Solutions

   Connection Systems is a global supplier of high-performance components and
electronic manufacturing services. Connection System's component technology can
be found in such diverse products as Internet routers, computer servers, mass
data storage and telecom switches. Connection Systems offers a total
interconnect solution with a broad suite of technologically differentiated
capabilities including printed circuit boards, high-speed, high-density
connectors, multi-gigabit backplane assemblies and complete systems integration
and test.

   A backplane plays the crucial roll of locating and supporting printed
circuit boards within a system, enabling them to "talk" to each other and to
the outside world. Connection Systems produces custom, large format backplanes,
up to .400 inches thick and 24 inches x 54 inches in size with up to 64 layers.
Connectors are devices that allow the backplane and other printed circuit
boards (sometimes called daughter cards) to plug together. High bandwidth
capability packed in a small amount of space is an important technological
advantage of Teradyne's connectors. Connection System's VHDM(R) and
VHDM-HSD(TM) connector families have become a standard in the industry for
high-speed, high-density interconnect. The GbX(TM) connector was introduced in
2001 to achieve even higher data rates and greater interconnection density. The
Connection Systems organization also provides electronic manufacturing
services, including backplane assembly, electro-mechanical integration of
sub-assemblies, and complete systems integration and test.

   An essential element of the Connection Systems business is its design and
applications engineering expertise at every step in the process. This expertise
helps customers balance critical cost and performance needs during system
design. In addition, by providing program management services, Connection
Systems becomes an extension of the customer's operation, delivering quick turn
prototypes and high technology production volumes.

Circuit Board Test and Inspection Solutions

   The central element of almost every electronic product is a printed circuit
board. A circuit board includes all the components and their interconnections
that cause the board to perform its intended functions. As more and more
product functionality is packed into smaller packages, such as PDAs, phone
handsets and laptop computers, both the circuit boards and their components are
increasingly complex. The circuit board manufacturing process

                                      4



is also complex and demands a number of inspection and test steps. Teradyne
circuit board test and inspection equipment is used throughout the
manufacturing process to ensure high production yields, to maintain overall
product quality, to diagnose faults quickly where and when they occur, and to
reduce total manufacturing cost. The Teradyne circuit board and inspection
product range includes the following products:

In-Circuit Test

   In-circuit test systems examine the assembled and soldered circuit board for
proper construction under both power-off and power-on conditions. Faulty
components or solder problems are identified quickly and precisely. Because of
their relatively low cost, high throughput and diagnostic accuracy, in-circuit
testers are used universally in every electronics production line. Teradyne
in-circuit products support a full range of circuit board test applications,
including prototype and ramp up, high-volume production, selective or sample
test and final or system test. Accordingly, Teradyne offers a wide variety of
capabilities and options with its Spectrum 8000-series, Z1800-series and GR
TestStation product lines. Specialized systems such as the GR Pilot and Javelin
"flying probers" round out one of the industry's broadest and most capable
product families.

Imaging Inspection

   As circuit boards become increasingly dense and complex, achieving the
electrical contact required for the traditional in-circuit test method is
becoming more difficult, time-consuming and expensive. "Loss of (electrical)
access" is a primary driver behind the increasing popularity of imaging
inspection systems, which examine the circuit board for physical qualities
including correct component presence and orientation, the absence of electrical
opens and solder quality. Teradyne's imaging inspection systems employ one of
two technologies: automated optical inspection ("AOI"), whereby a visual image
of the board is captured and analyzed; and automated x-ray inspection ("AXI"),
which captures an x-ray image of the board. Each technology has particular
strengths in analyzing various board defect classes. For example, AOI is the
preferred technology for evaluating and diagnosing component-related defects,
while AXI is the preferred technology for analyzing solder-related defects.
Teradyne's Optima 7000-series AOI systems employ advanced and patented
lighting, camera, software, and mechanics, resulting in highly reliable,
repeatable, and accurate optical inspection at high line speeds. The AXI
product line offers fast throughput with high resolution on both its
two-dimensional (2D) and three-dimensional (3D) models, and is the only product
line that includes a combined 2D/3D capability.

Functional Test

   Functional test systems examine the circuit board to determine whether it
will meet its performance specifications and whether it will properly perform
its intended "function." Functional testing is typically employed at the
conclusion of the manufacturing process, as the final check step, to ensure the
product will work as designed. Teradyne's functional test product line
encompasses a full range of functional test applications, including high-volume
production, final or system test, and field or depot diagnosis and repair.
Available products range from VXI and PXI open architecture instruments and
systems, to fully configured platforms for a wide range of manufacturing and
depot test applications. Teradyne functional test systems include focused
solutions for the communications, computer, and automotive markets, addressing
functional test requirements for products such as automotive engine control
units, telecom/datacom infrastructure equipment, wireless handheld devices, and
complex/mission critical military/aerospace products. All Teradyne functional
test solutions are designed specifically for the production test environment,
which helps ensure that the test system has been optimized for throughput,
reliability, and repeatability.

Design to Build Software

   Electronics manufacturers employ a variety of circuit board test and
inspection equipment throughout their production lines. This broad range of
circuit board test and inspection choices requires extensive test planning and
preparation, often referred to as "design to build" or "D2B". Teradyne's
Strategist software tool enables users to model, simulate, optimize and execute
a cost-effective test and inspection strategy, which optimally

                                      5



divides test and inspection tasks among the imaging inspection, in-circuit and
functional systems used on the manufacturing line. Once the strategy is
determined, the user then employs Teradyne's Alchemist software to generate
test software and documentation for the test and inspection equipment being
used in the manufacturing line.

Broadband Test Solutions

   Broadband Test Systems test the capacity and quality of telephone and cable
television lines connected to homes and businesses. These state-of-the-art
testing capabilities support cable and telephone company service provider's
goals to sell and deploy broadband services sooner and improve the efficiency
of qualification, provisioning, and customer care. Broadband Test Systems
provide voice network maintenance solutions for the communications industry.
Testing more than 120 million access lines worldwide for many of the world's
largest telecommunications companies, including British Telecommunications,
Deutsche Telecom and Verizon, Teradyne's 4TEL access network maintenance
systems reduce operating cost and increase customer satisfaction by reliably
detecting and identifying line faults within a telecommunications access
network. With ten years of Internet protocol testing experience, Teradyne also
provides products to telecommunications companies such as local exchange
carriers for Internet testing, customer care and voice network maintenance.

   Teradyne products within the Broadband Test Systems market include:

4TEL & 4TEL II Voice Test Systems

   Teradyne's 4TEL voice test system precisely identifies and isolates faults
within a telecommunications network, inside or outside customer premises,
without the need for customer isolation equipment. The 4TEL II voice test
system accurately isolates faults to such zones as exchange hardware, exchange
wiring, access cable, inside premises wiring and customer equipment.

   The 4TEL system quickly locates the precise geographic location of a fault,
enabling service providers to dispatch craftspeople to fix a fault, rather than
dispatching them to find the fault. The 4TEL voice test system also reliably
identify when a dispatch is not needed, such as when the problem exists in
customer-owned equipment. Teradyne's 4TEL system currently tests one seventh of
the world's voice lines.

NetFlare(TM) End-to-End Internet Testing

   Cable and telephone company service providers can reduce broadband service
call handling time with Teradyne's NetFlare system. This newly developed
technology allows the consumer or call center representative to emulate the
consumer's network experience and determine the source of a problem. For
example, NetFlare technology automatically measures throughput as the consumer
experiences it, determines whether the broadband service provider commitment is
met, and identifies the network source of the problem. NetFlare significantly
reduces average call handling time and reduces the necessity for further
technical support.

Celerity(TM) Speed Provisioning and Qualification Products

   Service providers need to know which cable lines between the central office
and the end user are qualified for digital subscriber lines ("DSL") and which
are not. Existing cable records are typically insufficient. Teradyne's Celerity
product qualifies millions of lines for DSL capability in hours, and develops a
database immediately showing which lines are qualified, which lines require
conditioning and which lines are disqualified. Celerity performs real time
testing that provides detailed loop qualification information and tests
in-service DSL lines, identifying the presence and dispatch location of faults
that affect data transmission. Celerity customers are able to significantly
reduce costs of deployment and identify new lines and high-speed lines for
increased revenue.

Diagnostic Solutions

   Diagnostic Solutions is a major supplier of automotive manufacturing test
and service bay diagnostic systems supporting vehicle electronics systems
throughout their lifecycle, from design through manufacturing to service.
Diagnostic Solutions products are used by automotive and transportation
original equipment manufacturers, as well as by independent service providers.

                                      6



Software Test Solutions

   Software Test Systems, which Teradyne divested in December 2000, are used by
a number of industries to test communications networks, computerized
telecommunication systems, and web based applications.

Summary of Net Sales by Operating Segment

   Teradyne's four principal operating segments accounted for the following
percentage of consolidated net sales for each of last three years:



                                                     % of consolidated net sales

Sales and Distribution

   Teradyne's systems are extremely complex and require extensive support both
by the customer and by Teradyne. Prices for Teradyne's systems can reach $3
million or more. In 2001, no single customer accounted for more than 10% of
Teradyne's consolidated net sales. In 2001, Teradyne's three largest customers
accounted for 24% of consolidated net sales.

   Direct sales to United States government agencies accounted for less than 1%
of consolidated net sales in 2001, 2000, and 1999. Approximately 5% of Circuit
Board Test and Inspection Systems sales in 2001 were to the United States
government agencies. Sales were also made within each of Teradyne's segments to
customers who are government contractors. Approximately 3% of Connection
Systems sales and approximately 27% of Circuit Board Test and Inspection
Systems sales fell into that category in 2001. On June 22, 2001, Teradyne sold
its aerospace and defense connector and backplane business to Amphenol
Corporation of Wallingford, Connecticut.

   Teradyne has sales and service offices located throughout North America,
South East Asia, Europe, Taiwan, Japan, and Korea as Teradyne's customers
outside the United States are located primarily in these geographic areas.
Teradyne sells in these areas predominantly through a direct sales force.
Primarily all of Teradyne's manufacturing activities are conducted in the
United States. Sales to customers outside the United States accounted for 49%
of consolidated net sales in 2001, 54% in 2000, and 52% in 1999. Sales to
customers located in Taiwan were 10% in 2001 and 2000. Sales are attributed to
geographic areas based on the location of the customer site.

   Teradyne is subject to the inherent risks involved in international trade,
such as:

    .  political and economic instability and acts of terrorism;
    .  restrictive trade policies;
    .  controls on funds transfer;
    .  currency fluctuations;
    .  difficulties in managing distributors;
    .  potentially adverse tax consequences; and
    .  the possibility of difficulty in accounts receivable collection.

   Teradyne attempts to reduce the effects of currency fluctuations by hedging
those currency exposures associated with certain assets and liabilities
denominated in non-functional currencies and by conducting some of its
international transactions in U.S. dollars or dollar equivalents. See also
"Item 7A. Quantitative and Qualitative Disclosures About Market Risks" and
"Note G: Financial Instruments" in Notes to Consolidated Financial Statements.

Competition

   Teradyne faces substantial competition, throughout the world in each of its
operating segments. Some of these competitors have substantial financial and
other resources to pursue engineering, manufacturing, marketing and
distribution of their products. Teradyne also faces competition from internal
suppliers at several of its customers. Some of Teradyne's competitors have
introduced or announced new products with certain performance characteristics
that may be considered equal or superior to those Teradyne currently offers.
Teradyne expects its competitors to continue to improve the performance of
their current products and to introduce new products or new technologies that
provide improved cost of ownership and performance characteristics. New product
introductions by competitors could cause a decline in sales or loss of market
acceptance of Teradyne's products. Moreover, increased competitive pressure
could lead to intensified price based competition, which could materially
adversely affect Teradyne's business, financial condition and results of
operations.

Backlog

   At December 31, 2001 and 2000, Teradyne's backlog of unfilled orders in each
of its four principal operating segments was as follows:

   Of the backlog at December 31, 2001, approximately 97% of the Semiconductor
Test Systems backlog, 100% of the Connection Systems backlog, 92% of Circuit
Board Test and Inspection Systems backlog, and 59% of the Other Test Systems
backlog is expected to be delivered in 2002. Teradyne's experience indicates
that a portion of orders included in the backlog may be canceled or
rescheduled. During 2001, Teradyne experienced an increase in the rescheduling
of delivery dates by some of its customers, and thus the timing of the delivery
of a significant portion of Teradyne's backlog is uncertain. In 2001, Teradyne
experienced cancellations of $285.5 million. Teradyne may experience additional
cancellations in the future. There are no seasonal factors related to the
backlog.

Raw Materials

   Teradyne's products require a wide variety of electronic and mechanical
components. Teradyne can experience occasional delays in obtaining timely
delivery of certain items. Additionally, Teradyne could experience a temporary
adverse impact if any of its sole source suppliers ceased to deliver products.
Any prolonged inability to obtain adequate supplies, or any other circumstances
that would require Teradyne to seek alternative sources of supply could have a
material adverse effect on its business, financial condition, and results of
operations.

Patents and Licenses

   Teradyne's development of its products, both hardware and software, is
largely based on proprietary information. Teradyne protects its rights in
proprietary information through various methods such as:

    .  copyrights;
    .  trademarks;
    .  patents and patent applications;
    .  software license agreements; and
    .  employee agreements.

   Any invalidation of Teradyne's intellectual property rights could have a
material adverse effect on its business.

                                      8



Employees

   As of December 31, 2001, Teradyne employed approximately 8,400 people. Since
the inception of Teradyne's business, there have been no work stoppages or
other labor disturbances. Teradyne has no collective bargaining contracts.

Engineering and Development Activities

   The highly technical nature of Teradyne's products requires a large and
continuing engineering and development effort. Engineering and development
expenditures were approximately $288.7 million in 2001, $348.0 million in 2000,
and $261.9 million in 1999. These expenditures amounted to approximately 20% of
consolidated net sales in 2001, 11% in 2000, and 15% in 1999.

Environmental Affairs

   Teradyne's manufacturing facilities are subject to numerous laws and
regulations designed to protect the environment, particularly from
manufacturing plant wastes and emissions. These laws include:

    .  The Comprehensive Environmental Response, Compensation, and Liability
       Act;
    .  The Superfund Amendment and Reauthorization Act of 1986;
    .  The Occupational Safety and Health Act;
    .  The Clean Air Act;
    .  The Clean Water Act;
    .  The Resource Conservation and Recovery Act of 1976; and
    .  The Hazardous and Solid Waste Amendments of 1984.

   In the opinion of management, the costs associated with complying with these
laws and regulations have not had and are currently not expected to have a
material effect upon the financial position or results of operations of
Teradyne.

   In 2001, Teradyne was designated as a "potentially responsible party"
("PRP") at two clean-up sites, one in California and one in Rhode Island.
Teradyne does not believe that it has any liability for the cleanup of the
California site, and has requested the state of California to remove Teradyne's
name from the list of PRPs, however, Teradyne has not yet received a reply. In
the opinion of management, the costs associated with complying with the
clean-up of this site, if required, are not expected to have a material effect
upon the financial position or results of operations of Teradyne. However,
Teradyne cannot predict what its liability, if any, may be for the clean-up of
this site and can give no assurance that it will not materially adversely
affect Teradyne's financial condition or results of operations. With respect to
the second site, in Rhode Island, additional information is currently being
collected to better understand Teradyne's financial obligations, if any, for
its portion of the clean-up of this site.

Item 3:  Legal Proceedings

   In connection with the August 2000 acquisition of each of Herco Technology
Corp., a California company, and Perception Laminates, Inc., a California
company, a complaint was filed by the former owners of those companies on or
about September 5, 2001 naming as defendants Teradyne and two of its executive
officers. The case was originally filed in the Superior Court in San Diego
County, California, and was subsequently removed by the defendants to federal
court. On or about November 14, 2001, Teradyne and the two individual
defendants filed a motion to dismiss the amended complaint in its entirety. The
federal court granted in part and denied in part that motion to dismiss. The
claims that were dismissed were dismissed with prejudice. At the federal
court's request, the plaintiffs filed a second amended complaint on March 4,
2002 setting forth their remaining claims. The second amended complaint
alleges, among other things, that the sale of Teradyne's common stock to the
former owners violated certain California securities statutes and common law,
and that Teradyne breached certain contractual obligations in the agreements
relating to the acquisitions. The second amended complaint seeks unspecified
damages, including compensatory, consequential and punitive damages, and
recovery of reasonable attorneys' fees and costs. On March 25, 2002, Teradyne
and the two individual defendants filed their answer to the second amended
complaint.

   Teradyne and two of its executive officers are named as defendants in three
purported class action complaints that were filed in the United States District
Court for the District of Massachusetts, Boston, Massachusetts, on or about
October 16, 2001, October 19, 2001 and November 7, 2001. The complaints allege,
among other things, that the defendants violated Sections 10(b) and 20(a) of
the Securities Exchange Act of 1934, by making, during the period from July 14,
2000 until October 17, 2000, material misrepresentations and omissions to the
investing public regarding Teradyne's business operations and future prospects.
The complaints seek unspecified damages, including compensatory damages and
recovery of reasonable attorneys' fees and costs.

                                      11



   Teradyne disputes all of the claims above and believes they are without
merit, and intends to defend vigorously against the lawsuits. However, an
adverse resolution of any of the lawsuits could have a material adverse effect
on Teradyne's financial position or results of operations. Teradyne is not
presently able to reasonably estimate potential losses, if any, related to any
of the lawsuits and therefore has not accrued for any potential losses from the
lawsuits.

   In addition, Teradyne is subject to legal proceedings and claims that arise
in the ordinary course of business. Management does not believe these actions
will have a material adverse effect on Teradyne's financial position or results
of operations.

Item 4:  Submission of Matters to a Vote of Security Holders.

   None.

Item 5:  Market for Registrant's Common Equity and Related Shareholder Matters

   The following table shows the market range for Teradyne's Common Stock based
on reported sale prices on the New York Stock Exchange.

2000 First Quarter.............................................. $ 94.94 $54.88
     Second Quarter.............................................  115.44  65.00
     Third Quarter..............................................   81.00  34.94
     Fourth Quarter.............................................   41.63  23.00


   The number of record holders of Teradyne's Common Stock at February 22, 2002
was 891.

   Teradyne has never paid cash dividends because it has been Teradyne's policy
to use earnings to finance expansion and growth. Payment of future cash
dividends will rest within the discretion of the Board of Directors and will
depend, among other things, upon Teradyne's earnings, capital requirements, and
financial condition. Teradyne presently expects to retain all of its earnings
for use in the business.

Item 7:  Management's Discussion and Analysis of Financial Condition and
         Results of Operations

   The following discussion should be read in conjunction with the consolidated
financial statements and notes thereto included elsewhere in this Annual Report
on Form 10-K. In addition to the historical information contained in this
document, the discussion in this Annual Report on Form 10-K contains
forward-looking statements, made pursuant to the Private Securities Litigation
Reform Act of 1995, that involve risks and uncertainties, such as statements of
Teradyne's plans, expectations and intentions. The cautionary statements made
in this Annual Report on Form 10-K should be read as being applicable to all
related forward-looking statements whenever they appear in this Annual Report
on Form 10-K. Teradyne's actual results could differ materially from the
results contemplated by these and any other forward-looking statements. Factors
that could contribute to such differences include those discussed below as well
as those cautionary statements and other factors set forth in "Certain Factors
That May Affect Future Results" and elsewhere herein.

Critical Accounting Policies and Estimates

   Teradyne has identified the policies discussed below as critical to
understanding its business and its results of operations. The impact and any
associated risks related to these policies on its business operations is
discussed throughout Management's Discussion and Analysis of Financial
Condition and Results of Operations where such policies affect its reported and
expected financial results.

   The preparation of consolidated financial statements requires Teradyne to
make estimates and judgments that affect the reported amounts of assets,
liabilities, revenues and expenses, and related disclosure of contingent
liabilities. On an on-going basis, Teradyne evaluates its estimates, including
those related to inventories, investments, intangible and other long-lived
assets, bad debts, income taxes, pensions, warranties, contingencies and
litigation. Teradyne bases its estimates on historical experience and on
appropriate and customary assumptions that are believed to be reasonable under
the circumstances, the results of which form the basis for making judgments
about the carrying values of assets and liabilities that are not readily
apparent from other sources. Actual results may differ from these estimates
under different assumptions or conditions.

   Teradyne recognizes revenue when there is persuasive evidence of an
arrangement, title and risk of loss have passed, delivery has occurred or the
services have been rendered, the sales price is fixed or determinable and
collection of the related receivable is reasonably assured. It is Teradyne's
policy to require an arrangement with its customers, either in the form of a
written or electronic contract or purchase order containing all of the terms
and conditions governing the arrangement, prior to the recognition of revenue.
Title and risk of loss generally passes to the customer at the time of delivery
of the product to a common carrier. At the time of the transaction, Teradyne
assesses whether the sales price is fixed or determinable based upon the
payment terms of the arrangement. If a significant portion of the sales price
is not due with normal payment terms, the sales price may not be deemed fixed
and revenue would be recognized as the amounts become due. Teradyne does not
offer a right of return on its products.

   Teradyne assesses collectibility based on a number of factors, including
past transaction and collection history with a customer and the
credit-worthiness of the customer. Teradyne performs on-going credit
evaluations of its customer's financial condition but generally does not
require collateral from its customers. If Teradyne determines that
collectibility of the sales price is not reasonably assured, revenue is
deferred until such time as collection becomes reasonably assured, which is
generally upon receipt of payment from the customer.

   Revenue is recognized upon delivery provided that customer acceptance
criteria can be demonstrated prior to shipment. Where the criteria cannot be
demonstrated prior to shipment, or in the case of new products, revenue is
deferred until acceptance has been received. For multiple element arrangements,
Teradyne defers the greater of the fair value of any undelivered elements of
the contract or the portion of the sales price which is not payable until the
undelivered elements are delivered. Teradyne also defers the portion of the
sales price that is not due until acceptance, which represents deferred profit.
Fair value is the price charged when the element is sold separately. In order
to recognize revenue the functionality of the undelivered element must not be
essential to the delivered element. Installation is not considered essential to
the functionality of the product as these services do not alter the product
capabilities, do not require specialized skills or tools and can be performed
by the customers or other vendors. In addition to installation, other elements
may include service arrangements and undelivered products. Teradyne's products
are generally subject to warranty and related costs are provided for in cost of
sales when product revenue is recognized.

                                      13



   Interconnection systems and electronic manufacturing assembly services
revenue is recognized upon shipment or delivery according to the shipping terms
of the arrangement as there is no installation required and there are no
contractual acceptance requirements.

   For certain contracts eligible for contract accounting under Statement of
Accounting Position No. 81-1, "Accounting for Performance of Construction-Type
and Certain Production-Type Contracts," revenue is recognized using the
percentage-of-completion accounting method based upon an efforts-expended
method. The software in these arrangements requires significant production,
modification or customization. In all cases, changes to total estimated costs
and anticipated losses, if any, are recognized in the period in which
determined. To date revenue under contract accounting has not been material.

   Inventories which include materials, labor and manufacturing overhead are
stated at the lower of cost (first-in, first-out basis) or net realizable
value. On a quarterly basis, Teradyne uses consistent methodologies to evaluate
all inventory for net realizable value. Teradyne records a provision for excess
and obsolete inventory when such an impairment is identified through the
quarterly review process. Excess and obsolete inventory, consisting of on-hand
and non-cancelable on-order inventory, in excess of estimated usage over the
next 12 months is written down to its estimated net realizable value, if less
than cost. The excess and obsolescence evaluation is based upon assumptions
about future demand, product mix and possible alternative uses. In 2001,
Teradyne recorded an inventory provision for excess and obsolete inventory of
$139.7 million which includes a writedown for discontinued product lines of
$34.5 million. If actual demand, product mix or possible alternative uses are
less favorable than those projected by management, additional inventory
write-downs may be required.

   On a quarterly basis, Teradyne evaluates the realizability of its deferred
tax assets and assesses the need for a valuation allowance. Realization of
Teradyne's net deferred tax assets is dependent on its ability to generate
approximately $415 million of future taxable income. Teradyne believes that it
is more likely than not that its net deferred tax assets will be realized based
on forecasted income, however, there can be no assurance that Teradyne will be
able to meet its expectations of future income. If Teradyne continues to incur
significant losses for an extended period of time, Teradyne could be required
to establish a valuation allowance against all or a significant portion of its
net deferred tax assets. To the extent Teradyne establishes a valuation
allowance, an expense will be recorded within the provision for income taxes
line in the statement of operations.

   Teradyne assesses the impairment of identifiable intangibles, long-lived
assets and related goodwill whenever events or changes in circumstances
indicate that the carrying value may not be recoverable. Factors Teradyne
considers important which could indicate an impairment include significant
underperformance relative to expected historical or projected future operating
results, significant changes in the manner of Teradyne's use of the acquired
asset or the strategy for Teradyne's overall business and significant negative
industry or economic trends. When Teradyne determines that the carrying value
of intangibles, long-lived assets and related goodwill may not be recoverable
based upon the existence of one or more of the above indicators of impairment,
Teradyne measures any impairment based on a projected discounted cash flow
method using a discount rate determined by its management to be commensurate
with the risk inherent in its current business model. During 2001, Teradyne
recorded charges of $32.3 million related to the impairment of certain excess
facilities and long-lived assets. Intangible assets, long-lived assets, and
goodwill amounted to $1.1 billion as of December 31, 2001.

   The volatility of the industries that Teradyne serves can cause certain of
its customers to experience shortages of cash flows, which can impact their
ability to make required payments. Teradyne maintains allowances for doubtful
accounts for estimated losses resulting from the inability of its customers to
make required payments. At December 31, 2001, this allowance for doubtful
accounts amounted to $6.3 million. Estimated allowances for doubtful accounts
are reviewed periodically taking into account the customer's current payment
history, the customer's current financial statements and other information
regarding the customer's credit worthiness. If the financial condition of
Teradyne's customers were to deteriorate, resulting in an impairment of their
ability to make payments, additional allowances may be required.

   On October 26, 2001, Teradyne completed its acquisition of GenRad, Inc. of
Westford, MA, a leading manufacturer of electronic automatic test equipment,
related software, and diagnostic solutions. GenRad's business has been made a
part of the Circuit Board Test and Inspection Systems operating segment. GenRad
activity is reflected in Teradyne's results of operations since the acquisition
date. See "Note F: Acquisitions and Divestitures" in Notes to Consolidated
Financial Statements for further information.

Results of Operations:

2001 compared to 2000

Revenue

   Teradyne's four principal operating segments accounted for the following
percentages of consolidated net sales for each of last three years:



                                                      % of consolidated

   Sales decreased 53% in 2001 to $1,440.6 million from $3,043.9 million in
2000. Semiconductor Test Systems sales decreased 65%, to $717.7 million in 2001
from $2,044.0 million in 2000, Connection Systems sales to unaffiliated
customers decreased 26%, to $540.8 million in 2001 from $734.6 million in 2000,
and Circuit Board Test and Inspection Systems sales decreased 6%, to $132.4
million in 2001 from $141.2 million in 2000. These decreases reflect the
overall economic and industry market conditions described below. Circuit Board
Test and Inspection Systems sales include the two-month impact of the GenRad
acquisition which contributed sales of $19.0 million. Other Test Systems sales
decreased 60%, to $49.7 million in 2001 from $124.1 million in 2000, which
principally reflects the divestiture of Software Test Systems at the end of
2000 as well as the overall economic and industry market conditions described
below. During the fourth quarter of 2000, Teradyne implemented Staff Accounting
Bulletin No. 101 "Revenue Recognition in Financial Statements" (SAB 101)
retroactive to the beginning of the year. Included in 2001 sales was $98.7
million related to shipments of customer orders in 2000 where title was
retained by Teradyne until customer payment in order to perfect a security
interest. Teradyne no longer retains title until customer payment.

   Teradyne's business has been adversely impacted by the slowdown in economies
worldwide including the effects of the hostilities begun in September 2001.
Teradyne has also been adversely affected by the cyclical nature of the
electronics and semiconductor industries, which experience recurring periods of
oversupply of products and equipment of the type Teradyne sells. These factors
have resulted in a downturn in the demand for Teradyne's products. During 2001,
orders declined significantly across all of Teradyne's product lines when
compared with the orders Teradyne received during 2000. The reduction in net
orders across Teradyne for 2001 compared with 2000 was approximately $2,512.7
million. Teradyne's experience in previous downturns has been that orders
improve as Teradyne's customers' capital expenditures increase. At present,
however, Teradyne cannot say how long the current downturn will last or when
the situation will improve. In the absence of significant improvement, orders
could remain low or decline further, and the amount of Teradyne's inventory,
deferred tax assets, and certain long-lived assets considered realizable could
be significantly reduced.

   In 2001 and 2000, no single customer accounted for more than 10% of
consolidated net sales. In 2001, Teradyne's three largest customers accounted
for 24% of consolidated net sales.

Bookings

   Net orders decreased 76% to $808.2 million in 2001 from $3,320.9 million in
2000. Net orders decreased in all operating segments and were led by a 85%
decrease in Semiconductor Test Systems net orders. Connection Systems net
orders, Circuit Board Test and Inspection Systems net orders, and Other Test
Systems net orders decreased 64%, 33%, and 78%, respectively. Teradyne
experienced cancellations of $285.5 million during 2001. Teradyne's net orders
for its four principal operating segments for 2001 and 2000 were as follows:

   Teradyne's backlog decreased 45% to $763.0 million in 2001 from $1,382.1
million in 2000. At December 31, 2001 and 2000, Teradyne's backlog of unfilled
orders for its four principal operating segments was as follows:



                                                      (in millions)

                                      16



   Customers may delay delivery of products or cancel orders suddenly and
without significant notice, subject to possible cancellation penalties. Due to
possible customer changes in delivery schedules and cancellation of orders,
Teradyne's backlog at any particular date is not necessarily indicative of the
actual sales for any succeeding period. Delays in delivery schedules and/or
cancellations of backlog during any particular period could have a material
adverse effect on Teradyne's business and results of operations.

Gross Margin

   Certain costs in 2001 and 2000 have been reclassified from cost of sales
into engineering and development and selling and administrative. These
reclassified costs consist of new product development costs incurred in
manufacturing engineering, test technology and applications engineering costs
supporting sales. The costs reclassified from cost of sales to engineering and
development represent work performed to develop and implement manufacturing and
test processes focused on the introduction of new product platforms. The costs
reclassified from cost of sales to selling and administrative represent the
development of applications programming used to demonstrate new product
capabilities. The impact of the reclassifications is detailed below:

             Selling and administrative.     17,296       15,221


   Cost of sales, excluding the charges described below, increased to 71% of
sales in 2001 from 53% of sales in 2000. The percentage increase in 2001 was
attributable to the decreased utilization of Teradyne's manufacturing capacity,
as sales volume decreased while certain components of costs of sales remained
fixed. The increase in the percentage of cost of sales was also impacted to a
lesser extent by increased competitive price pressure as current semiconductor
products mature and the mix of Teradyne's business changes as Connection
Systems and Circuit Board Test and Inspection System sales, which have lower
gross margins, become a larger percentage of Teradyne's business.

   Teradyne introduced a number of new products in 2001. Generally, Teradyne's
new products begin their product life with lower gross margins and margins
improve as volume purchases increase and cost reduction activities are
implemented. There can be no assurance that significant improvements in gross
margins will be achieved on current or new Teradyne products through either
volume purchases or cost reduction activities.

   Cost of sales related to inventory provisions and other charges for asset
impairments and vacated leases was $159.8 million in 2001. Inventory provision
for excess and obsolete inventory was $105.2 million in 2001, which excludes
the inventory writedowns for product line discontinuance, compared to $27.5
million in 2000, included in cost of sales, representing a 5% increase. The
increase in the inventory provision was caused by the worldwide economic
slowdown during 2001. Between 2000 and 2001, orders declined by approximately
$2,512.7 million, a 76% decrease. This drop in orders combined with lead time
requirements for inventory procurement and Teradyne's new product introduction
plans necessitated additional charges for excess and obsolete inventory. During
2001, Teradyne recorded an inventory writedown in Semiconductor Test Systems
due to the discontinuance of the Flash 750 product line of $32.3 million and
related asset impairments of $4.6 million. In the third and fourth quarters of
2001, Teradyne recorded a charge of $15.4 million for certain impaired
manufacturing assets and vacated space under operating leases at Connection
Systems.

Engineering and Development

   Engineering and development expenses, as a percentage of sales, increased to
20% in 2001 from 11% in 2000, with spending decreasing by $59.4 million. This
spending decrease was primarily due to lower material costs and the impact of
workforce reductions, salary cuts, and furloughs in Semiconductor Test Systems
and Circuit Board Test and Inspection Systems, excluding the impact of the
GenRad acquisition. Connection Systems engineering and development spending
increased 5% from 2000 to 2001.


                                      17



Selling and Administrative

   Selling and administrative expenses increased to 19% of sales in 2001 from
12% of sales in 2000, with spending decreasing by $107.7 million. The decrease
in spending was principally due to certain cost containment programs such as
workforce reductions, salary cuts, and furloughs.

Restructuring and Other Charges

   Restructuring and other charges include a workforce reduction and early
retirement provision of $37.3 million, a charge for a Connection Systems
impaired facility of $12.0 million, a charge for impaired assets of $1.9
million relating to the discontinuance of the Flash 750 product line in
Semiconductor Test Systems, and a charge for vacated space under certain
operating leases of $1.7 million in Circuit Board Test and Inspection Systems.
There were approximately 2,900 employees terminated in 2001 across all
functional groups. These terminations will result in future cost savings in
2002 of approximately $132.0 million. Teradyne has paid $23.8 million in
severance benefits during 2001. All remaining severance benefits for employees
terminated in 2001 will be paid by the fourth quarter of 2002.

   Below is a table summarizing activity relating to restructuring and other
charges:

   The accrual for severance and benefits is reflected in accrued employees'
compensation and withholdings and the accrual for lease payments on vacated
facilities is reflected in other accrued liabilities.

Interest income and expense

   Interest income decreased by $2.4 million to $22.7 million in 2001 compared
to $25.1 million in 2000. The decrease in 2001 was attributable to decreases in
the average invested balances and lower interest rates. Interest expense
increased by $2.3 million as a result of interest expense for two months
associated with Teradyne's convertible notes.

Other income and expense

   Included in other income in 2001 is a gain from the sale of Connections
Systems aerospace and defense business of $14.8 million. Included in other
expense for 2001 is Teradyne's proportionate share of a loss related to an
equity method investment of $7.0 million.

Income before taxes

   (Loss) income before income taxes and cumulative effect of change in
accounting principle was a loss of $326.2 million in 2001 compared to income of
$739.6 million in 2000. Semiconductor Test Systems, Connection Systems, Circuit
Board Test and Inspection Systems, and Other Test Systems income before income
taxes decreased $907.2 million, $167.5 million, $40.3 million, and $3.3
million, respectively in 2001 due to decreased sales in each group and the
market conditions described above.

                                      18



Income taxes

   Teradyne's effective tax rate benefit was 38% in 2001. The effective tax
rate provision for the year ended 2000 was 30%. The change in the tax rate is a
result of a loss in 2001. In 2000, Teradyne was able to reduce its effective
tax rate with tax benefits from its foreign sales corporation and Ireland
manufacturing operations.

   On a quarterly basis, Teradyne evaluates the realizability of its deferred
tax assets and assesses the need for a valuation allowance. Realization of
Teradyne's net deferred tax assets is dependent on its ability to generate
approximately $415 million of future taxable income. Teradyne believes that it
is more likely than not that its net deferred tax assets will be realized based
on forecasted income. However, if Teradyne continues to incur significant
losses for an extended period of time, it could be required to establish a
valuation allowance against all or a significant portion of its net deferred
tax assets. To the extent Teradyne establishes a valuation allowance, an
expense will be recorded within the provision for income taxes line in the
statement of operations.

   In response to an adverse World Trade Organization (WTO) finding that the
U.S. Foreign Sales Credit (FSC) tax provisions were a prohibited export
subsidy, the U.S. repealed FSC and enacted replacement legislation
(Extraterritorial Income Exclusion Act of 2000). The European Union filed a WTO
challenge to the new law and the WTO has upheld the European Union's challenge.
The U.S. has decided to appeal and the appellate process and final resolution
of this matter could extend beyond 2002. The U.S. government and industry
groups are evaluating options. It is not possible to predict what impact, if
any, this issue will have on future earnings pending final resolution of the
challenge. During the years ended December 31, 2001, 2000, and 1999, the FSC
benefited Teradyne's effective tax rate as follows:

                 Export sales corporation (0.7%) (4.8%) (4.7%)


2000 compared to 1999

Revenue

   Sales increased 70% in 2000 to a record $3,043.9 million from $1,790.9
million in 1999. Semiconductor Test Systems shipments increased by 69% due to
increased sales to semiconductor manufacturers and subcontractors as these
customers increased capacity to meet their customer's requirements. Sales of
Connection Systems to unaffiliated customers grew 97% as a result of
significant growth in demand from networking, data storage, and other high
technology customers. Circuit Board Test and Inspection Systems sales increased
by 19% from 1999. Other Test Systems sales increased 40% from 1999 with
increases in Broadband Test Systems of 10% and Software Test Systems of 64%.
Due to the sale of a majority interest in the software test business in
December 2000, Software Test Systems revenue will not be reflected on an
on-going basis.

Bookings

   Incoming net orders increased 52% from $2,190.6 million in 1999 to a record
$3,320.9 million in 2000. Net orders increased in all operating segments and
were led by a 159% increase in Connection Systems net orders. Semiconductor
Test Systems net orders increased 24%. Broadband Test Systems net orders
increased 77% and Circuit Board Test and Inspection Systems and Software Test
Systems increased 26% and 70%, respectively. Teradyne's backlog increased 41%
to a record $1,382.1 million.

Gross Margin

   Certain costs in 2000 and 1999 have been reclassified from cost of sales
into engineering and development and selling and administrative. These
reclassified costs consist of new product development costs incurred in
manufacturing engineering, test technology and applications engineering costs
supporting sales. The costs

                                      19



reclassified from cost of sales to engineering and development represent work
performed to develop and implement manufacturing and test processes focused on
the introduction of new product platforms. The costs reclassified from cost of
sales to selling and administrative represent the development of applications
programming used to demonstrate new product capabilities. The impact of the
reclassifications is detailed below:



                                          Year Ended   Year Ended

             Selling and administrative.     15,221       10,245


   Costs of sales as a percentage of sales decreased from 56% of sales in 1999
to 53% of sales in 2000. The decrease in cost of sales was primarily due to the
increased utilization of Teradyne's manufacturing overhead as sales volume
increased while certain components of cost of sales remained fixed.

Engineering and Development

   Engineering and development expenses decreased from 15% of sales in 1999 to
11% of sales in 2000, even though spending increased $86.2 million. The
increase in spending was primarily due to new product development expenses in
Semiconductor Test Systems, and, to a lesser extent, increased expenses related
to product development in Connection Systems, Circuit Board Test and Inspection
Systems, and Software Test Systems.

Selling and Administrative

   Selling and administrative expenses as a percentage of sales decreased from
15% in 1999 to 12% in 2000. Spending increased by $111.1 million year over year
in support of increased Semiconductor Test Systems, Connection Systems, and
Software Test Systems sales.

Interest income and expense

   Interest income increased $7.8 million to $25.1 million in 2000 compared to
$17.3 million in 1999. Interest income increased due to an increase in
Teradyne's average invested balances and higher interest rates.

Other income and expense

   Included in other income in 2000 is an immaterial gain relating to the
divestiture of the software test business.

Income before taxes

   Income before income taxes and cumulative effect of change in accounting
principle increased $465.8 million from $273.8 million in 1999 to $739.6
million in 2000. Semiconductor Test Systems, Connection Systems, Circuit Board
Test and Inspection Systems, and Other Test Systems income before income taxes
increased $387.4 million, $91.8 million, $7.0 million, and $9.5 million,
respectively in 2000 due to increased sales in each group.

Income taxes

   Teradyne's effective tax rate was 30% in 2000 and 1999. Teradyne continued
to utilize export sales corporation benefits and other tax benefits to operate
below the U.S. statutory rate of 35%.

                                      20



Liquidity and Capital Resources

   Teradyne's cash, cash equivalents and marketable securities balance
increased $121.8 million in 2001, to $586.2 million. Teradyne used cash from
operating activities of $79.0 million in 2001 and generated cash from operating
activities in 2000 and 1999 of $470.9 million and $367.5 million, respectively.
Net income (loss), adjusted to exclude the effects of non-cash items, used cash
of $77.1 million in 2001, and provided cash of $501.6 million and $279.7
million in 2000 and 1999, respectively. Changes in operating assets and
liabilities net of businesses sold and acquired used cash of $1.9 million in
2001 as accounts payable and accruals balances decreased as purchases slowed.
The decrease in accounts payable and accruals was partially offset by reduced
accounts receivable and inventory balances. Changes in operating assets and
liabilities used cash of $30.7 million in 2000 and generated cash of $87.7
million in 1999.

   Teradyne used $247.3 million of cash for investing activities in 2001,
$312.3 million in 2000, and $244.8 million in 1999. Investing activities
consist of purchases, sales, and maturities of marketable securities, proceeds
from the sale of businesses, cash acquired in business acquisitions, and
purchases of capital assets to support long-term growth. Capital expenditures
decreased by $56.8 million in 2001 compared with 2000, primarily in the
Semiconductor Test Systems segment. This was due to the actions taken by
Teradyne in 2001 to reduce planned capital expenditures due to current market
conditions. Capital expenditures were $241.4 million in 2001, $298.2 million in
2000, and $151.2 million in 1999.

   Teradyne generated $401.5 million of cash from financing activities in 2001,
used $97.5 million in 2000, and used $126.8 million in 1999. Financing
activities include the issuance of convertible notes, mortgage borrowings,
sales and repurchases of Teradyne's common stock, as well as repayments of
debt. In 2001, Teradyne assumed debt of $89.7 million from the GenRad
acquisition which Teradyne repaid on October 26, 2001. During 2001, 2000, and
1999 issuances of common stock under stock option and stock purchase plans
generated $58.5 million, $55.3 million, and $82.3 million, respectively.
Teradyne used cash for the acquisition of treasury stock of $147.5 million and
$207.8 million in 2000 and 1999, respectively. Since 1996, Teradyne has used
$540.8 million of cash to repurchase 20.0 million shares of its common stock on
the open market though no cash was used in 2001 to repurchase shares of common
stock.

   On October 24, 2001, Teradyne sold $400 million principal amount of 3.75%
Convertible Senior Notes due 2006 (the "Notes") in a private placement and
received net proceeds of $389 million. The Notes are convertible at the option
of the holders at a rate which is equivalent to a conversion price of
approximately $26.00 per share, which is equal to a conversion rate of
approximately 38.4615 shares of common stock per $1,000 principal amount of
Notes. The Notes are redeemable by Teradyne at any time after October 18, 2004
at specified prices. Teradyne will begin making annual interest payments of up
to $15 million, paid semi-annually, on the Notes commencing on April 15, 2002.
The Notes are senior unsecured obligations of Teradyne that rank equally with
Teradyne's existing and future unsecured and unsubordinated indebtedness. In
the event of a change in control by which Teradyne merges with or sells
substantially all of its assets to a third party, the holders of the Notes may
be able to require Teradyne to redeem some or all of the Notes either in
discounted Teradyne common stock or in cash. On February 8, 2002, the
Securities and Exchange Commission declared effective a Registration Statement
on Form S-3 covering both the Notes and the shares of common stock into which
they can be converted.

   On December 19, 2001, Teradyne obtained a loan of approximately $45 million
in the form of a 7.5% mortgage loan maturing on January 1, 2007, (the
"Mortgage"). Principal payments are made according to a twenty-year
amortization schedule through December 2006, with the remaining principal due
on January 1, 2007. Teradyne began making monthly principal and interest
payments of $0.4 million on February 1, 2002.

   On October 26, 2001, Teradyne completed its acquisition of GenRad, Inc. of
Westford, MA, a leading manufacturer of electronic automatic test equipment,
related software and diagnostic solutions. GenRad's business has been made part
of the Circuit Board Test and Inspection Systems operating segment. Under the
terms of the acquisition, each outstanding share of GenRad common stock was
converted into 0.1733 shares of Teradyne common stock. The total number of
Teradyne shares exchanged for the shares of GenRad, based on the shares of
GenRad outstanding as of the closing, was approximately 5.0 million.

                                      21

   Teradyne believes its cash, cash equivalents, and marketable securities
balance of $586.2 million, together with a tax refund of $85.2 million received
in March 2002, will be sufficient to meet working capital and expenditure needs
for the foreseeable future. Depending on market conditions and funding
requirements, Teradyne may seek additional external financing.

   Inflation has not had a significant long-term impact on earnings.

Recently Issued Accounting Pronouncements

   In July 2001, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards No. 141 ("SFAS 141"), "Business
Combinations." SFAS 141 requires the purchase method of accounting for business
combinations initiated after June 30, 2001 and eliminates the
pooling-of-interest method.

   In July 2001, FASB issued SFAS 142, "Goodwill and Other Intangible Assets",
which is effective for Teradyne on January 1, 2002. SFAS 142 requires, among
other things, the discontinuance of goodwill amortization and includes
provisions for the reclassification of certain existing recognized intangibles
as goodwill, reassessment of the useful lives of existing recognized
intangibles, and reclassification of certain intangibles out of previously
reported goodwill. In 2001, Teradyne recorded goodwill amortization of
approximately $3.9 million. At December 31, 2001 Teradyne had $190.3 million of
goodwill which will not be amortized. In 2002, Teradyne will record
amortization of approximately $7.4 million relating to other intangibles
primarily in connection with the GenRad acquisition. SFAS 142 also requires
Teradyne to complete a transitional goodwill impairment test six months from
the date of adoption. Teradyne has completed a preliminary evaluation of the
impact of SFAS 142 and currently does not expect to record a goodwill
impairment.

   In August 2001, FASB issued SFAS 143, "Accounting for Obligations Associated
with the Retirement of Long-Lived Assets." SFAS 143 provides the accounting
requirements for retirement obligations associated with tangible long-lived
assets. SFAS 143 is effective for financial statements for fiscal years
beginning after June 15, 2002. Teradyne has determined that SFAS 143 will not
have an impact on its financial position and results of operations.

   In October 2001, FASB issued SFAS 144, "Accounting for the Impairment or
Disposal of Long-Lived Assets." SFAS 144 requires one method of accounting for
long lived assets disposed of by sale. SFAS 144 is effective for financial
statements issued for fiscal years beginning after December 15, 2001. Teradyne
has adopted SFAS 144 effective January 1, 2002. SFAS 144 did not have an impact
on Teradyne's financial position or results of operations.

                                      22



Certain Factors That May Affect Future Results

   From time to time, information provided by Teradyne, statements made by its
employees or information included in its filings with the Securities and
Exchange Commission (including this Form 10-K and Teradyne's Annual Report to
Shareholders) contain statements which are not purely historical facts, but are
forward looking statements, made under the Safe Harbor provisions of the
Private Securities Litigation Reform Act of 1995, which involve risks and
uncertainties. In particular, forward looking statements are contained in "Item
1: Business", and in "Item 7: Management's Discussion and Analysis of Financial
Condition and Results of Operations" relating to projections, plans, and
objectives for Teradyne's business, financial condition, operating results,
future economic performance or statements relating to the sufficiency of
capital to meet working capital, planned capital expenditures, and expectations
as to customer orders. Teradyne's actual future results may differ
significantly from those stated in any forward looking statements. Factors that
may cause such differences include, but are not limited to, the factors
discussed below. Each of these factors, and others, are discussed from time to
time in Teradyne's filings with the Securities and Exchange Commission.

Teradyne's Business Is Impacted by the Slowdown in Economies Worldwide.

   Teradyne's business has been negatively impacted by the slowdown in the
economies of the United States, Asia and elsewhere that began in the second
half of 2000. The uncertainty regarding the growth rate of the worldwide
economies has caused companies to reduce capital investment and may cause
further reduction of such investments. These reductions have been particularly
severe in the electronics and semiconductor industry which Teradyne serves and
have contributed to Teradyne incurring losses in recent periods. Teradyne
cannot predict if or when the growth rate of worldwide economies will rebound,
whether the growth rate of its business will rebound when the worldwide
economies begin to grow, or if or when Teradyne will return to profitability.
While Teradyne's diverse business may allow it to perform better than some
companies in periods of economic decline, the effects of the economic decline
are being felt across all of Teradyne's business segments and have
significantly slowed customer orders.

Teradyne's Business is Dependent on the Current and Anticipated Market for
Electronics.

   Teradyne's business and results of operations depend in significant part
upon capital expenditures of manufacturers of semiconductors and other
electronics, which in turn depend upon the current and anticipated market
demand for those products. The current and anticipated market demand for
electronics has been impacted by the economic slowdown that began in the latter
portions of 2000 and the effects of the hostilities begun in September 2001.
Historically, the electronic and semiconductor industry has been highly
cyclical with recurring periods of over-supply, which often have had a severe
negative effect on demand for test equipment, including systems manufactured
and marketed by Teradyne. Teradyne believes that the markets for newer
generations of electronic products such as those that Teradyne manufactures and
markets will also be subject to similar fluctuations. Teradyne is dependent on
the timing of customer orders and the deferral or cancellation of previous
customer orders could have an adverse effect on its results of operations.
Teradyne cannot assure you that the downward trend in new orders will turn
around in the future or that any increase in sales or new orders for a calendar
quarter will be sustained in subsequent quarters. In addition, any factor
adversely affecting the electronics industry or particular segments within the
electronics industry may adversely affect Teradyne's business, financial
condition and operating results.

Teradyne Has Taken and Expects to Continue to Take Measures to Address the
Current Slowdown in the Market for Its Products Which Could Have Long-term
Negative Effects on Teradyne's Business.

   Teradyne has taken and expects to take additional measures to address the
current slowdown in the market for its products. In particular, Teradyne has
reduced its workforce, frozen hiring, delayed salary increases, reduced the pay
of substantially all employees, implemented furloughs, discontinued its Flash
750 memory product line, recorded asset impairment charges and reduced its
planned capital expenditures and expense

                                      23



budgets. These measures have reduced expenses in the face of decreased revenues
due to decreased or cancelled customer orders. However, each measure Teradyne
has taken and any additional measures taken in the future to contain
expenditures could have long-term negative effects on Teradyne's business by
reducing its pool of technical talent, decreasing or slowing improvements in
its products, and making it more difficult for Teradyne to respond to customers
or competitors.

Teradyne's Business May Be Adversely Impacted by Acquisitions Which May Affect
Its Ability to Manage and Maintain Its Business.

   Since Teradyne's inception, it has acquired a number of businesses. In the
future, Teradyne may undertake additional acquisitions of businesses that
complement its existing operations. Such past or future acquisitions could
involve a number of risks, including:

    .  the possibility that one or more such acquisitions may not close due to
       closing conditions in the acquisition agreements, the inability to
       obtain regulatory approval, or the inability to meet conditions imposed
       for government or court approvals for the transaction;
    .  the diversion of the attention of management and other key personnel;
    .  the inability to effectively integrate an acquired business into
       Teradyne's culture, product and service delivery methodology and other
       standards, controls, procedures and policies;
    .  the inability to retain the management, key personnel and other
       employees of an acquired business;
    .  the inability to retain the customers of an acquired business;
    .  the possibility that Teradyne's reputation will be adversely affected by
       customer satisfaction problems of an acquired business;
    .  potential known or unknown liabilities associated with an acquired
       business, including but not limited to regulatory, environmental and tax
       liabilities;
    .  the amortization of acquired identifiable intangibles, which may
       adversely affect Teradyne's reported results of operations; and
    .  litigation which has or which may arise in the future in connection with
       such acquisitions.

   For example, in connection with the August 2000 acquisition of each of Herco
Technology Corp., a California company, and Perception Laminates, Inc., a
California company, a complaint was filed by the former owners of those
companies on or about September 5, 2001 naming as defendants Teradyne and two
of its executive officers. This case is further described in "Item 3: Legal
Proceedings" on this Form 10-K. Teradyne cannot predict the outcome of the
lawsuit at this time, and can give no assurance that it will not materially
adversely affect Teradyne's financial position or results of operations.

   In addition to the foregoing, any acquired business could significantly
underperform relative to Teradyne's expectations.

Teradyne Currently Faces, and in the Future May Be the Subject of, Securities
Class Action Litigation Due to Past or Future Stock Price Volatility.

   When the market price of a stock has been volatile, holders of that stock
sometimes institute securities class action litigation against the company that
issued the stock. Currently, Teradyne and two if its executive officers are
named as defendants in three purported class action complaints that were filed
in the United States District Court for the District of Massachusetts, Boston,
Massachusetts, on or about October 16, 2001, October 19, 2001 and November 7,
2001. The complaints allege, among other things, that the defendants violated
Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, by making,
during the period from July 14, 2000 until October 17, 2000, material
misrepresentations and omissions to the investing public regarding Teradyne's
business operations and future prospects. The complaints seek unspecified
damages, including compensatory damages and recovery of reasonable attorneys'
fees and costs. Teradyne strongly believes that the purported class action
complaints lack merit and it intends to defend against the claims vigorously.
However, Teradyne could

                                      24



incur substantial costs defending the lawsuits. The lawsuits could also divert
the time and attention of Teradyne's management. Teradyne cannot predict the
outcome of the lawsuits at this time, and can give no assurance that they will
not materially adversely affect Teradyne's financial position or results of
operations.

Teradyne's Business May be Adversely Impacted by Divestitures of Lines of
Business Which May Affect Its Ability to Manage and Maintain Its Business.

   Since Teradyne's inception, it has divested itself of certain lines of
business. In the future, Teradyne may undertake additional such divestitures.
Such past or future divestitures could involve a number of risks, including:

    .  the diversion of the attention of management and other key personnel;
    .  disruptions and other effects caused by the divestiture of a line of
       business on Teradyne's culture, product and service delivery methodology
       and other standards, controls, procedures and policies;
    .  customer satisfaction problems caused by the loss of a divested line of
       business; and
    .  the decreased diversification of Teradyne's product lines caused by the
       divestiture of a line of business which may make Teradyne's operating
       results subject to increased market fluctuations.

If Teradyne Is Unable to Protect Its Intellectual Property, Teradyne May Lose a
Valuable Asset or May Incur Costly Litigation to Protect Its Rights.

   Teradyne's products incorporate technology that it protects in several ways,
including patents, copyrights and trade secrets. While Teradyne believes that
its patents, copyrights and trade secrets have value in general, no single one
is in itself essential. At times, Teradyne has been notified that it may be in
violation of patents held by others. An assertion of patent infringement
against Teradyne, if successful, could have a material adverse effect on its
ability to sell its products, or could require a lengthy and expensive defense
which could adversely affect its operating results.

If Teradyne Fails to Develop New Technologies to Adapt to Its Customers' Needs
and if Its Customers Fail to Accept Its New Products, Teradyne's Revenues Will
Be Adversely Affected.

   Teradyne believes that its technological position depends primarily on the
technical competence and creative ability of its engineers. Teradyne's
development of new technologies, commercialization of those technologies into
products, and market acceptance and customer demand for those products is
critical to Teradyne's success. Successful product development and introduction
depends upon a number of factors, including:

    .  new product selection;
    .  development of competitive products by competitors;
    .  timely and efficient completion of product design;
    .  timely and efficient implementation of manufacturing; and
    .  assembly processes and product performance at customer locations.

Intense Competition in Teradyne's Industry May Affect Its Revenues.

   Teradyne faces substantial competition throughout the world in each of its
operating segments. Some of Teradyne's competitors have substantial financial
and other resources to pursue engineering, manufacturing, marketing and
distribution of their products. Teradyne also faces competition from internal
suppliers at several of its customers. Some of Teradyne's competitors have
introduced or announced new products with certain performance characteristics
which may be considered equal or superior to those Teradyne currently offers.
Teradyne expects its competitors to continue to improve the performance of
their current products and to introduce new products or new technologies that
provide improved cost of ownership and performance characteristics. New

                                      25



product introductions by competitors could cause a decline in sales or loss of
market acceptance of Teradyne's products. Moreover, increased competitive
pressure could lead to intensified price based competition, which could
materially adversely affect Teradyne's business, financial condition and
results of operations.

Teradyne Is Subject to Risks of Operating Internationally.

   Teradyne derives a significant portion of its total revenue from customers
outside the United States. Teradyne's international sales are subject to
significant risks and difficulties, including:

    .  unexpected changes in legal and regulatory requirements and in policy
       changes affecting international markets;
    .  changes in tariffs and exchange rates;
    .  political and economic instability and acts of terrorism;
    .  difficulties in accounts receivable collection;
    .  difficulties in staffing and managing international operations; and
    .  potentially adverse tax consequences, such as the World Trade
       Organization's dispute against the U.S. Foreign Sales Credit.

Teradyne May Incur Significant Liabilities if It Fails to Comply With
Environmental Regulations.

   Teradyne is subject to environmental regulations relating to the use,
storage, discharge, site cleanup, and disposal of hazardous chemicals used in
its manufacturing processes. If Teradyne fails to comply with present and
future regulations, or is required to perform site remediation, Teradyne could
be subject to future liabilities or the suspension of production. Present and
future regulations may also:

    .  restrict Teradyne's ability to expand its facilities;
    .  require Teradyne to acquire costly equipment; or
    .  require Teradyne to incur other significant costs and expenses.

Teradyne Has Substantially Increased Its Indebtedness.

   On October 24, 2001, Teradyne completed a private placement of $400 million
principal amount of 3.75% Convertible Senior Notes (the "Notes") due 2006 and
received net proceeds of $389 million. On December 19, 2001, Teradyne obtained
a loan of approximately $45 million in the form of a 7.5% mortgage loan
maturing on January 1, 2007 (the "Mortgage"). As a result, Teradyne has
incurred approximately $445 million principal amount of additional
indebtedness, substantially increasing its ratio of debt to total
capitalization. Teradyne may incur substantial additional indebtedness in the
future. The level of Teradyne's indebtedness, among other things, could:

    .  make it difficult for Teradyne to make payments on its debt and other
       obligations;
    .  make it difficult for Teradyne to obtain any necessary future financing
       for working capital, capital expenditures, debt service requirements or
       other purposes;
    .  require the dedication of a substantial portion of any cash flow from
       operations to service for indebtedness, thereby reducing the amount of
       cash flow available for other purposes, including capital expenditures;
    .  limit Teradyne's flexibility in planning for, or reacting to changes in,
       its business and the industries in which Teradyne competes;
    .  place Teradyne at a possible competitive disadvantage with respect to
       less leveraged competitors and competitors that have better access to
       capital resources; and
    .  make Teradyne more vulnerable in the event of a further downturn in its
       business.
   There can be no assurance that Teradyne will be able to meet its debt
service obligations, including its obligations under the Notes and the Mortgage.

                                      26



Teradyne May Not Be Able to Satisfy a Change in Control Offer.

   The indenture governing the Notes contains provisions that apply to a change
in control of Teradyne. If someone triggers a change in control as defined in
the indenture, Teradyne may be required to offer to purchase the Notes with
cash. If Teradyne has to make that offer, Teradyne cannot be sure that it will
have enough funds to pay for all the Notes that the holders could tender.

   In the event of a change in control of Teradyne, the mortgage lender may
elect to declare all amounts due under the Mortgage to be immediately due and
payable, and may elect to take possession of or sell the property subject to
the Mortgage.

Teradyne May Not Be Able to Pay Its Debt and Other Obligations.

   If Teradyne's cash flow is inadequate to meet its obligations, Teradyne
could face substantial liquidity problems. If Teradyne is unable to generate
sufficient cash flow or otherwise obtain funds necessary to make required
payments on the Notes, the Mortgage, or certain of its other obligations,
Teradyne would be in default under the terms thereof, which would permit the
holders of those obligations to accelerate their maturity and also could cause
defaults under future indebtedness Teradyne may incur. Any such default could
have a material adverse effect on Teradyne's business, prospects, financial
position and operating results. In addition, Teradyne cannot assure that it
would be able to repay amounts due in respect of the Notes or the Mortgage if
payment of those obligations were to be accelerated following the occurrence of
any other event of default as defined in the instruments creating those
obligations. Moreover, Teradyne cannot assure that it will have sufficient
funds or will be able to arrange for financing to pay the principal amount due
on the Notes or the Mortgage at their respective maturities.

Teradyne May Need Additional Financing, Which Could Be Difficult to Obtain.

   Teradyne expects that its existing cash and marketable securities, cash
generated from operations, the proceeds of the Notes offering in October 2001
and the proceeds from the Mortgage financing in December 2001, will be
sufficient to meet Teradyne's cash requirements to fund operations and expected
capital expenditures for the foreseeable future. In the event Teradyne may need
to raise additional funds, Teradyne cannot be certain that it will be able to
obtain such additional financing on favorable terms, if at all. Further, if
Teradyne issues additional equity securities, stockholders may experience
additional dilution or the new equity securities may have rights, preferences
or privileges senior to those of existing holders of common stock. Future
financings may place restrictions on how Teradyne operates its business. If
Teradyne cannot raise funds on acceptable terms, if and when needed, Teradyne
may not be able to develop or enhance its products and services, take advantage
of future opportunities, grow its business or respond to competitive pressures,
which could seriously harm Teradyne's business.

Provisions of Teradyne's Charter and By-Laws and Massachusetts Law Make a
Takeover of Teradyne More Difficult.

   Teradyne's basic corporate documents, its stockholder rights plan, and
Massachusetts law contain provisions that could discourage, delay or prevent a
change in the control of Teradyne, even if a change of control might be
regarded as beneficial to some or all of Teradyne's stockholders.

Teradyne's Operating Results Are Likely to Fluctuate Significantly.

   Teradyne's quarterly and annual operating results are affected by a wide
variety of factors that could materially adversely affect revenues and
profitability, including:

    .  competitive pressures on selling prices;
    .  the timing of customer orders and the deferral or cancellation of orders
       previously received;
    .  provisions for excess and obsolete inventory;
    .  changes in product mix;
    .  Teradyne's ability to introduce new products and technologies on a
       timely basis;
    .  the introduction of products and technologies by Teradyne's competitors;

                                      27



    .  market acceptance of Teradyne's and its competitors' products;
    .  fulfilling backlog on a timely basis;
    .  reliance on sole source suppliers;
    .  potential retrofit costs;
    .  the level of orders received which can be shipped in a quarter; and
    .  the timing of investments in engineering and development.

   In particular, due to Teradyne's introduction of a number of new, complex
test systems in 2001 and the planned introduction of other such systems in
2002, there can be no assurance that Teradyne will not experience delays in
shipment of its products or that its products will achieve customer acceptance.

   As a result of the foregoing and other factors, Teradyne has and may
continue to experience material fluctuations in future operating results on a
quarterly or annual basis which could materially and adversely affect its
business, financial condition, operating results and stock price.

Item 7a:  Quantitative and Qualitative Disclosures About Market Risks

Concentration of Credit Risk

   Financial instruments which potentially subject Teradyne to concentrations
of credit risk consist principally of cash investments, forward currency
contracts, and accounts receivable. Teradyne maintains cash investments
primarily in U.S. Treasury and government agency securities and corporate debt
securities, rated AA or higher, which have minimal credit risk. Teradyne places
forward currency contracts with high credit-quality financial institutions in
order to minimize credit risk exposure. Concentrations of credit risk with
respect to accounts receivable are limited due to the large number of
geographically dispersed customers. Teradyne performs ongoing credit
evaluations of its customers' financial condition and does not require
collateral to secure accounts receivable.

Exchange Rate Risk Management

   Teradyne regularly enters into forward contracts in European and Japanese
currencies to hedge its overseas net monetary position and has in the past
entered into forward contracts to hedge non-U.S. currency forecasted
transactions. Forward currency contracts generally have maturities of less than
one year. These contracts are used to reduce Teradyne's risk associated with
exchange rate movements, as gains and losses on these contracts are intended to
offset exchange losses and gains on underlying exposures. Teradyne does not
engage in currency speculation.

   At December 31, 2001, the face amount of outstanding forward currency
contracts to buy U.S. dollars to hedge those currency exposures associated with
certain assets and liabilities denominated in non-functional currencies was
$11.0 million. A 10% fluctuation in exchange rates for these currencies would
change the fair value by approximately $1.3 million. However, since these
contracts hedge non-U.S. currency assets and liabilities, any change in the
fair value of the contracts would be offset by opposite changes in the
underlying value of these assets and liabilities being hedged. The hypothetical
movement was estimated by calculating the fair value of the forward currency
contracts at December 31, 2001 and comparing that with those calculated using
hypothetical forward currency exchange rates.

Interest Rate Risk Management

   At December 31, 2001, the fair value of outstanding short and long-term
marketable securities was approximately $270.0 million. A hypothetical 10%
increase in interest rates for securities contained in the investment portfolio
would change the fair value by approximately $2.3 million. Market risk was
estimated as the potential decrease in the fair value resulting from a
hypothetical increase in interest rates for issues contained in the investment
portfolio.

                             REPORT OF MANAGEMENT

   Management is responsible for the preparation and integrity of the
consolidated financial statements appearing in this Annual Report on Form 10-K.
The financial statements were prepared in conformity with accounting principles
generally accepted in the United States of America appropriate in the
circumstances and, accordingly, include some amounts based on management's best
judgments and estimates. Financial information in this Annual Report on Form
10-K is consistent with that in the financial statements.

   Management is responsible for maintaining a system of internal business
controls and procedures to provide reasonable assurance, at an appropriate
cost/benefit relationship, that assets are safeguarded and that transactions
are authorized, recorded and reported properly. The internal control system is
augmented by appropriate reviews by management, written policies and
guidelines, careful selection and training of qualified personnel and a written
code of business ethics applicable to all employees of Teradyne and its
subsidiaries. Management believes that Teradyne's internal controls provide
reasonable assurance that assets are safeguarded against material loss from
unauthorized use or disposition and that the financial records are reliable for
preparing financial statements and other data and maintaining accountability
for assets.

   The Audit Committee of the Board of Directors, composed solely of Directors
who are not employees or officers of Teradyne, meets periodically with the
independent accountants, internal auditors and management to discuss internal
business controls, auditing and financial reporting matters. The Audit
Committee reviews with the independent accountants the scope and results of the
audit. The Audit Committee also meets with the independent accountants without
management present to ensure that the independent accountants have free access
to the Audit Committee.

   The independent accountants, PricewaterhouseCoopers LLP, are engaged to
audit the consolidated financial statements of Teradyne and to conduct such
tests and related procedures as they deem necessary in accordance with auditing
standards generally accepted in the United States of America. The opinion of
the independent accountants, based upon their audits of the consolidated
financial statements, is contained in this Annual Report on Form 10-K.

Item 8:  Financial Statements and Supplementary Data

                       REPORT OF INDEPENDENT ACCOUNTANTS

   To the Directors and Shareholders of Teradyne, Inc.:

   In our opinion, the consolidated financial statements listed in the index
appearing under Item 14(a)(1) present fairly, in all material respects, the
financial position of Teradyne, Inc. and its subsidiaries at December 31, 2001
and 2000, and the results of their operations and their cash flows for each of
the three years in the period ended December 31, 2001 in conformity with
accounting principles generally accepted in the United States of America. In
addition, in our opinion, the financial statement schedule listed in the index
appearing under Item 14(a)(2) presents fairly, in all material respects, the
information set forth therein when read in conjunction with the related
consolidated financial statements. These financial statements and financial
statement schedule are the responsibility of the Company's management; our
responsibility is to express an opinion on these financial statements and
financial statement schedule based on our audits. We conducted our audits of
these statements in accordance with auditing standards generally accepted in
the United States of America, which 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,
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.

   As discussed in Note C to the consolidated financial statements, during the
year ended December 31, 2000 the Company changed its method of recognizing
revenue.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

A.   THE COMPANY

   Teradyne, Inc. is the world's largest supplier of automatic test equipment
and is also a leading provider of high performance interconnection systems and
electronic manufacturing services.

   Teradyne's automatic test equipment products include systems that:

    .  test semiconductors ("Semiconductor Test Systems");
    .  test and inspect circuit-boards ("Circuit Board Test and Inspection
       Systems"); and
    .  test high speed voice and data communication ("Broadband Test Systems").

   Teradyne's interconnection systems products and services ("Connection
Systems") include:

    .  high bandwidth backplane assemblies and associated connectors used in
       electronic systems; and
    .  electronic manufacturing services of assemblies that include Teradyne
       backplanes and connectors.

   Broadband Test Systems, Diagnostic Solutions, and, prior to 2001, Software
Test Systems have been combined into "Other Test Systems" for purposes of
disclosing Teradyne's reportable segments.

B.   ACCOUNTING POLICIES

Basis of Presentation

   The consolidated financial statements include the accounts of Teradyne and
its subsidiaries. All significant intercompany balances and transactions are
eliminated. Certain prior years' amounts were reclassified to conform to the
current year presentation.

   Certain costs in 2001, 2000, and 1999 have been reclassified from cost of
sales into engineering and development and selling and administrative. These
reclassified costs consist of new product development costs incurred in
manufacturing engineering, test technology and applications engineering costs
supporting sales. The costs reclassified from cost of sales to engineering and
development represent work performed to develop and implement manufacturing and
test processes focused on the introduction of new product platforms. The costs
reclassified from cost of sales to selling and administrative represent the
development of applications programming used to demonstrate new product
capabilities.

   On October 26, 2001 Teradyne completed its acquisition of GenRad, Inc. of
Westford, MA, a leading manufacturer of electronic automatic test equipment,
related software and diagnostic solutions. The GenRad business has been made
part of the Circuit Board Test and Inspection Systems operating segment. GenRad
activity is reflected in Teradyne's results of operations since the acquisition
date.

Preparation of Financial Statements and Use of Estimates

   The preparation of consolidated financial statements requires Teradyne to
make estimates and judgments that affect the reported amounts of assets,
liabilities, revenues and expenses, and related disclosure of contingent
liabilities. On an on-going basis, Teradyne evaluates its estimates, including
those related to inventories, investments, intangible and other long-lived
assets, bad debts, income taxes, pensions, warranties, contingencies and
litigation. Teradyne bases its estimates on historical experience and on
appropriate and customary assumptions that are believed to be reasonable under
the circumstances, the results of which form the basis for making judgments
about the carrying values of assets and liabilities that are not readily
apparent from other sources. Actual results may differ from these estimates
under different assumptions or conditions.

B.  ACCOUNTING POLICIES--(Continued)

Revenue Recognition

   In accordance with the guidance provided by the Securities and Exchange
Commission's Staff Accounting Bulletin No. 101, "Revenue Recognition in
Financial Statements", Teradyne recognizes revenue when there is persuasive
evidence of an arrangement, title and risk of loss have passed, delivery has
occurred or the services have been rendered, the sales price is fixed or
determinable and collection of the related receivable is reasonably assured.

   For equipment where there is hardware and software that is incidental to the
product, revenue is recognized upon shipment provided that customer acceptance
criteria can be demonstrated prior to shipment. Where the criteria cannot be
demonstrated prior to shipment, or in the case of new products, revenue is
deferred until acceptance has been received. For multiple element arrangements,
Teradyne defers the greater of the fair value of any undelivered elements of
the contract or the portion of the sales price which is not payable until the
undelivered elements are delivered. Teradyne also defers the portion of the
sales price that is not due until acceptance, which represents deferred profit.
Fair value is the price charged when the element is sold separately. In order
to recognize revenue the functionality of the undelivered element must not be
essential to the delivered element. Installation is not considered essential to
the functionality of the product as these services do not alter the product
capabilities, do not require specialized skills or tools and can be performed
by the customers or other vendors. In addition to installation, other elements
may include service arrangements and undelivered products. Teradyne's products
are generally subject to warranty and related costs are provided for in cost of
sales when product revenue is recognized.

   Interconnection systems and electronic manufacturing assembly services
revenue is recognized upon shipment or delivery according to the shipping terms
of the arrangement as there is no installation required and there are no
contractual acceptance requirements.

   For transactions involving the sale of software which is not incidental to
the product, revenue is recognized in accordance with American Institute of
Certified Public Accountants ("AICPA") Statement of Position No. 97-2 (SOP No.
97-2), "Software Revenue Recognition", as amended by SOP No. 98-9 "Modification
of SOP 97-2, Software Revenue Recognition, With Respect to Certain
Transactions." Teradyne recognizes revenue when there is persuasive evidence of
an arrangement, delivery has occurred, the sales price is fixed or determinable
and collectibility is probable. Revenue is deferred in instances when vendor
specific objective evidence of fair value of undelivered elements is not
determinable. Vendor specific evidence of fair value is the price charged when
the element is sold separately. Revenue for the separate elements is only
recognized where the functionality of the undelivered element is not essential
to the delivered element.

   For certain contracts eligible for contract accounting under SOP No. 81-1
"Accounting for Performance of Construction-type and Certain Production-Type
Contracts", revenue is recognized using the percentage-of-completion accounting
method based upon an efforts-expended method. The software in these
arrangements requires significant production, modification or customization. In
all cases, changes to total estimated costs and anticipated losses, if any, are
recognized in the period in which determined.

Inventories

   Inventories which include materials, labor and manufacturing overhead are
stated at the lower of cost (first-in, first-out basis) or net realizable
value. On a quarterly basis, Teradyne uses consistent methodologies to evaluate
all inventory for net realizable value. Teradyne records a provision for excess
and obsolete inventory when such an impairment is identified through the
quarterly review process. Excess and obsolete inventory, consisting of on-hand
and non-cancelable on-order inventory, in excess of estimated usage over the
next 12 months is written down to its estimated net realizable value, if less
than cost. The excess and obsolescence evaluation is based upon assumptions
about future demand, product mix and possible alternative uses.

B.  ACCOUNTING POLICIES--(Continued)

Property, Plant, and Equipment

   Property, plant, and equipment are stated at cost and depreciated over the
estimated useful lives of the assets. Leasehold improvements and major renewals
are capitalized and included in property, plant, and equipment accounts while
expenditures for maintenance and repairs and minor renewals are charged to
expense. When assets are retired, the assets and related allowances for
depreciation and amortization are removed from the accounts and any resulting
gain or loss is reflected in operations.

   Teradyne provides for depreciation of its assets principally on the
straight-line method with the cost of the assets being charged to expense over
their useful lives as follows:



               Buildings........................... 40 years
                                                 
               Buildings improvements.............. 5 to 10 years
               Leasehold improvements.............. 5 to 10 years
               Furniture and fixtures.............. 10 years
               Test systems manufactured internally 6 years
               Machinery and equipment............. 3 to 5 years
               Software............................ 3 to 5 years
               Test technology..................... 2 years


Goodwill and Intangible and Other Assets

   Goodwill and intangible assets are amortized over their estimated useful
economic life using the straight line method and are carried at cost less
accumulated amortization. Goodwill resulting from the GenRad acquisition which
was completed after June 30, 2001 is not being amortized in accordance with the
requirements of SFAS No. 142, "Goodwill and Other Intangible Assets". Beginning
January 1, 2002 all other goodwill amortization will cease in accordance with
SFAS No. 142.

   In accordance with Statement of Financial Accounting Standards No. 121
("SFAS 121") "Accounting for the Impairment of Long-Lived Assets and for
Long-Lived Assets to Be Disposed Of", Teradyne reviews long-lived assets for
impairment whenever events or changes in business circumstances indicate that
the carrying amount of the assets may not be fully recoverable or that the
useful lives of these assets are no longer appropriate. Each impairment test is
based on a comparison of the estimated undiscounted cash flows to the recorded
value of the asset. If an impairment is indicated, the asset is written down to
its estimated fair value based on a discounted cash flow analysis. The cash
flow estimates used to determine the impairment, if any, contain management's
best estimates using appropriate assumptions and projections at that time.

Engineering and Development Costs

   Teradyne's products are highly technical in nature and require a large and
continuing engineering and development effort. Software development costs
incurred prior to the establishment of technological feasibility are charged to
expense. Software development costs incurred subsequent to the establishment of
technological feasibility are capitalized until the product is available for
release to customers. To date, the period between achieving technological
feasibility and general availability of the product has been short and software
development costs eligible for capitalization have not been material.
Engineering and development costs are expensed as incurred.

B.  ACCOUNTING POLICIES--(Continued)

Advertising Costs

   Teradyne expenses all advertising costs as incurred. Advertising costs were
$10.3 million, $16.8 million, and $9.0 million in 2001, 2000, and 1999,
respectively.

Investments in Other Companies

   Teradyne holds minority interests in public and private companies having
operations or technology in areas within its strategic focus. These investments
are included in other long-term assets and include investments accounted for at
cost and under the equity method of accounting. Under the equity method of
accounting, which generally applies to investments that represent a 20 to 50
percent ownership of the equity securities of the investees, Teradyne's
proportionate share of the earnings or losses of the investees is included in
other income and expense. Teradyne records an impairment charge when it
believes an investment has experienced a decline in value that is
other-than-temporary. At December 31, 2001, these investments were $14.4
million.

Income Taxes

   Deferred tax assets and liabilites are determined based on differences
between financial reporting and tax bases of assets and liabilities and are
measured using the enacted tax rates and laws that will be in effect when the
differences are expected to reverse. The measurement of deferred tax assets is
reduced by a valuation allowance if, based upon weighted available evidence, it
is more likely than not that some or all of the deferred tax assets will not be
realized.

   U.S. Federal taxes are provided for on the retained earnings of non-U.S.
sales and service subsidiaries whose earnings are expected to be remitted to
the United States. U.S. Federal taxes are not provided for on the earnings of a
non-U.S. manufacturing subsidiary which are expected to be reinvested
indefinitely in operations outside the U.S.

Translation of Non U.S. Currencies

   Assets and liabilities of non U.S. subsidiaries, which are denominated in
currencies other than the U.S. dollar, are remeasured into U.S. dollars at
rates of exchange in effect at the end of the fiscal year except nonmonetary
assets and liabilities which are remeasured using historical exchange rates.
Revenue and expense amounts are remeasured using an average of exchange rates
in effect during the year, except those amounts related to nonmonetary assets
and liabilities, which are remeasured at historical exchange rates. Net
realized gains and losses resulting from currency remeasurement are included in
operations.

Net Income (Loss) per Common Share

   Basic net income (loss) per common share is calculated by dividing net
income (loss) by the weighted average number of common shares outstanding
during the period. Diluted net income (loss) per common share is calculated by
dividing net income (loss) by the sum of the weighted average number of common
shares plus

additional common shares that would have been outstanding if potential dilutive
common shares had been issued for granted stock option and stock purchase
rights.

Other Comprehensive Income (Loss)

   Teradyne reports comprehensive income (loss) in accordance with Statement of
Financial Accounting Standards No. 130, "Reporting Comprehensive Income" (SFAS
130). Comprehensive income (loss) includes net income (loss), minimum pension
liability adjustments, and unrealized gains and losses on certain investments
in debt and equity securities.

C.  CHANGE IN ACCOUNTING PRINCIPLE

   In December 1999, the Securities and Exchange Commission issued Staff
Accounting Bulletin No. 101, "Revenue Recognition in Financial Statements" (SAB
101). SAB 101 summarizes certain areas of the Staff's views in applying
generally accepted accounting principles to revenue recognition in financial
statements. During the fourth quarter of 2000, Teradyne implemented the SEC's
SAB 101 guidelines, retroactive to the beginning of the year. This was reported
as a cumulative effect of a change in accounting principle as of January 1,
2000. The cumulative effect of the change in accounting principle on prior
years resulted in a charge to income of $64.1 million (net of income taxes of
$27.5 million) or $0.35 per diluted share which has been included in income for
the fiscal year ending December 31, 2000. For the fiscal year ending December
31, 2000, Teradyne recognized $126.1 million in revenue that is included in the
cumulative effect adjustment as of January 1, 2000. The results for the first
three quarters of fiscal year ending December 31, 2000 have been restated in
accordance with SAB 101. Included in 2001 sales was $98.7 million which
resulted in $48.8 million of income (net of tax of $20.9 million) related to
shipments in 2000 where title was retained until payment. Title is no longer
retained until payment as a normal business practice. Prior years do not
reflect the change in accounting principle as the effect could not be
reasonably determined.

D.  RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

   In July 2001, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards No. 141 ("SFAS 141"), "Business
Combinations." SFAS 141 requires the purchase method of accounting for business
combinations initiated after June 30, 2001 and eliminates the
pooling-of-interest method.

   In July 2001, FASB issued SFAS 142, "Goodwill and Other Intangible Assets",
which is effective for Teradyne on January 1, 2002. SFAS 142 requires, among
other things, the discontinuance of goodwill amortization and includes
provisions for the reclassification of certain existing recognized intangibles
as goodwill, reassessment of the useful lives of existing recognized
intangibles, and reclassification of certain intangibles out of previously
reported goodwill. In 2001, Teradyne recorded goodwill amortization of
approximately $3.9 million. At December 31, 2001 Teradyne had goodwill of
$190.3 million which will not be amortized. In 2002, Teradyne will record
amortization of approximately $7.4 million relating to other intangibles
primarily in connection with the GenRad acquisition. SFAS 142 also requires
Teradyne to complete a transitional goodwill impairment test six months from
the date of adoption. Teradyne has completed a preliminary evaluation of the
impact of SFAS 142 and currently does not expect to record a goodwill
impairment.

   In August 2001, FASB issued SFAS 143, "Accounting for Obligations Associated
with the Retirement of Long-Lived Assets." SFAS 143 provides the accounting
requirements for retirement obligations associated with tangible long-lived
assets. SFAS 143 is effective for financial statements for fiscal years
beginning after June 15, 2002. Teradyne has determined that SFAS 143 will not
have an impact on its financial position and results of operations.

D.  RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS--(Continued)

   In October 2001, FASB issued SFAS 144, "Accounting for the Impairment or
Disposal of Long-Lived Assets." SFAS 144 requires one method of accounting for
long lived assets disposed of by sale. SFAS 144 is effective for financial
statements issued for fiscal years beginning after December 15, 2001. Teradyne
has adopted SFAS 144 effective January 1, 2002. SFAS 144 did not have an impact
on Teradyne's financial position or results of operations.

E.  RISKS AND UNCERTAINTIES

   Teradyne's future results of operations involve a number of risks and
uncertainties. These factors include, but are not limited to, the slowdown in
economies worldwide, the effects of the hostilities begun in September 2001,
the current and anticipated market for electronics, risks associated with any
measures Teradyne takes to address the current slowdown in the market,
enforcement of Teradyne's intellectual property rights, failure to develop new
technologies, risks associated with acquisitions and divestitures, securities
class action litigation due to past or future stock activity, competition,
risks of operating internationally, risks associated with obligations and
potential liabilities under environmental regulations, Teradyne's debt service
obligations with respect to its recent sale of convertible senior notes and a
mortgage financing with respect to certain of its owned real estate assets, the
difficulty in obtaining future financing if needed, provisions of Teradyne's
charter and by-laws and Massachusetts law that make a takeover of Teradyne more
difficult, competitive pricing pressures, changes in product mix, timing of
customer orders or any deferral or cancellation of orders previously received,
market acceptance of Teradyne's products, new product introductions from
Teradyne's competitors, reliance on sole source suppliers, potential retrofit
costs, and the timing of investments in engineering and development. At
present, Teradyne cannot say how long the current business downturn will last
or when the situation will improve. In the absence of significant improvement,
orders could remain low or decline further, and the amount of Teradyne's
inventory, deferred tax assets, and certain long-lived assets considered
realizable could be significantly reduced.

F.  ACQUISITIONS AND DIVESTITURES

   On October 26, 2001 Teradyne completed its acquisition of GenRad, Inc. of
Westford, MA, a leading manufacturer of electronic automatic test equipment,
related software, and diagnostic solutions. GenRad's business has been made
part of the Circuit Board Test and Inspection Systems operating segment. Under
the terms of the acquisition, each outstanding share of GenRad common stock was
converted into 0.1733 shares of Teradyne common stock. Under the terms of the
acquisition, Teradyne assumed approximately $89.7 million of debt which
Teradyne repaid on October 26, 2001. The results of GenRad have been included
since the acquisition date.

   The primary reasons for Teradyne's acquisition of GenRad, and the factors
that contributed to a purchase price that resulted in recognition of goodwill,
are:

    .  the combination of Teradyne's circuit board test systems with GenRad
       will strengthen Teradyne's product offerings;
    .  Teradyne's global presence in Europe and Asia among large electronics
       manufacturing services companies and original equipment manufacturers in
       the circuit board test and inspection markets will be strengthened as a
       result of the acquisition; and
    .  to enable Teradyne to compete more effectively in the circuit board test
       and inspection markets.

   Based on the exchange ratio of 0.1733 shares of Teradyne common stock for
each GenRad share, Teradyne issued approximately 5.0 million common shares and
1.2 million vested employee stock options in the exchange, which increased
common stockholders' equity by approximately $185.5 million. The common stock
was valued at $34.90 per share, which was Teradyne's average common stock price
over a five-day trading period, which

included the public announcement date of August 2, 2001 and two days before and
after the public announcement date. The employee stock options were valued
using the Black-Scholes option pricing model, based on following assumptions
prevalent at the August 2001 announcement date:



                          Expected life (years).   6.0

   This transaction was accounted for using the purchase method of accounting
as required by SFAS 141, "Business Combinations," which was issued in the
second quarter of 2001.

   The purchase price allocation is preliminary and subject to future
adjustment based on the completion of facility exit and restructuring plans.
Based on the purchase price allocation, the following table summarizes the fair

   On June 22, 2001, Teradyne sold its aerospace and defense connector and
backplane business to Amphenol Corporation of Wallingford, Connecticut for cash
proceeds of $26.3 million. This transaction resulted in a pre-tax gain of $14.8
million which has been recorded in other income and expense.

   On August 15, 2000, Teradyne acquired two California-based companies, both
in the printed circuit board (PCB) industry: Herco Technology Corp. of San
Diego, California, a fabricator of printed circuit boards, and Perception
Laminates, Inc. of La Verne, California, which supplies PCB laminates and is a
major supplier to Herco. The acquisitions are part of the Connection Systems
operating segment. The cost of the acquired companies was $104.5 million with
approximately 1.8 million shares of common stock issued. The acquisitions were
accounted for using the purchase method of accounting and accordingly, the
results have been included in our consolidated results of operations from the
date of acquisition. Goodwill resulting from the acquisitions will no longer be
amortized beginning in 2002.

   On December 29, 2000, Teradyne sold a controlling interest in its software
test business to an investor group led by Matrix Partners of Waltham,
Massachusetts for approximately $28.7 million. The gain from the sale was
immaterial. Teradyne has retained an ownership position of approximately 21% in
the new company called Empirix. Teradyne has accounted for its investment in
Empirix under the equity method of accounting. At December 31, 2001, the
carrying value of Teradyne's investment in Empirix was zero.

G.  FINANCIAL INSTRUMENTS

Cash Equivalents

   Teradyne considers all highly liquid investments with original maturities of
three months or less at the date of acquisition to be cash equivalents.

Marketable Securities

   Teradyne classifies investments in marketable securities as trading,
available-for-sale or held-to-maturity at the time of purchase and periodically
re-evaluates such classification. There were no securities classified as
trading at December 31, 2001 or 2000. Securities are classified as
held-to-maturity when Teradyne has the positive intent and ability to hold the
securities to maturity. Held-to-maturity securities are stated at cost with
corresponding premiums or discounts amortized over the life of the investment
to interest income. Securities classified as available-for-sale are reported at
fair value. Realized gains and losses and declines in value judged to be
other-than-temporary on available-for-sale securities are included in interest
income. Unrealized gains and losses are included in accumulated other
comprehensive income. The cost of securities sold is based on the specific
identification method.

   The short-term marketable securities mature in less than one year. Long-term
marketable securities have maturities of one to five years. At December 31,
2001 and 2000 these investments are reported as follows (in thousands):

Other

   As of December 31, 2001, the estimated fair value of Teradyne's convertible
notes was approximately $547 million compared to the carrying value of $400
million. The estimated fair value of the convertible notes is based on the
quoted market price of the convertible notes on December 31, 2001. The quoted
market price for the convertible notes primarily reflects the conversion value
of the notes into Teradyne's common stock.

   Fair values for Teradyne's non-convertible debt were determined based on
interest rates that are currently available to Teradyne for the issuance of
debt with similar terms and remaining maturities for debt issues and
approximate carrying values.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)


G.  FINANCIAL INSTRUMENTS--(Continued)

   For all other balance sheet financial instruments, the carrying amount
approximates fair value.

Derivatives

   Teradyne adopted SFAS 133, "Accounting for Derivative Instruments and
Hedging Activities," as amended by SFAS 137 and SFAS 138 in the first quarter
of 2001. SFAS 133 requires Teradyne to recognize all derivatives on the balance
sheet at fair value. Adoption of SFAS 133 did not have a material impact on
Teradyne's financial position or results of operations.

   Teradyne conducts business in a number of foreign countries, with certain
transactions denominated in local currencies. The purpose of Teradyne's foreign
currency management is to minimize the effect of exchange rate fluctuations on
certain foreign denominated net monetary assets and anticipated cash flows. The
terms of currency instruments used for hedging purposes are consistent with the
timing of the transactions being hedged. Teradyne does not use derivative
financial instruments for trading or speculative purposes.

   Teradyne enters into foreign currency forward contracts to hedge currency
exposures associated with monetary assets and liabilities denominated in
non-functional currencies. These contracts are used to reduce Teradyne's risk
associated with exchange rate movements, as gains and losses on these contracts
are intended to offset exchange losses and gains on underlying exposures.
Changes in the fair value of these derivatives are recorded immediately in
earnings which are used to offset the changes in the underlying net monetary
position being hedged.

   Teradyne periodically hedges certain forecasted foreign currency denominated
sales, over a maximum period of twelve months. The derivatives are designated
as cash-flow hedges, and changes in their fair value are carried in accumulated
other comprehensive income until the underlying transaction occurs. Once the
underlying forecasted transaction occurs, the appropriate gain or loss from the
derivative designated as a hedge of the transaction is reclassified from
accumulated other comprehensive income to net sales. During 2001 the amount of
net realized gains from cash-flow hedges was immaterial. As of December 31,
2001, there were no outstanding cash-flow hedges and therefore there is no
amount to be reclassified from accumulated other comprehensive income.

   At December 31, 2001, Teradyne had the following forward currency contracts
to buy U.S. dollars for non U.S. currencies with the following notional amounts
totaling $11.0 million; $2.4 million Japanese Yen, $3.6 million Euro, $4.4
million British pound sterling, and $0.6 million Swedish Krona. At December 31,
2000, the face amount of outstanding forward currency contracts to buy U.S.
dollars for non U.S. currencies was $73.0 million. The fair value of the
outstanding contracts at December 31, 2001 was $0.2 million. Realized gains
related to forward contracts hedging net monetary position were $4.1 million,
$7.0 million, and $0.1 million for 2001, 2000, and 1999, respectively. Both the
contract gains and losses and the gains and losses on the items being hedged
are included in selling and administrative expenses.

   Teradyne holds warrants to purchase 0.3 million shares of common stock of
LogicVision, a public technology company, at an exercise price of $4.86 per
share. In accordance with SFAS 133, Teradyne recorded a gain of $2.0 million in
other income for the fair value of the warrants for the year ended December 31,
2001. The fair value of the warrant is included in other assets.

Concentration of Credit Risk

   Financial instruments which potentially subject Teradyne to concentrations
of credit risk consist principally of marketable securities, forward currency
contracts, and accounts receivable. Teradyne maintains cash investments
primarily in U.S. Treasury and government agency securities and corporate debt
securities, rated

AA or higher, which have minimal credit risk. Teradyne places forward currency
contracts with high credit-quality financial institutions in order to minimize
credit risk exposure. Concentrations of credit risk with respect to accounts
receivable are limited due to the large number of geographically dispersed
customers. Teradyne performs ongoing credit evaluations of its customers'
financial condition but does not require collateral to secure accounts
receivable.

thereafter.

Convertible Senior Notes

   In 2001, Teradyne sold $400 million principal amount of 3.75% Convertible
Senior Notes due 2006 (the "Notes") in a private placement and received net
proceeds of $389 million. The Notes are convertible at the option of the
holders at a rate which is equivalent to a conversion price of approximately
$26.00 per share, which is equal to a conversion rate of approximately 38.4615
shares of common stock per $1,000 principal amount of Notes. On or after
October 18, 2004, Teradyne may redeem the Notes in whole or in part at the
prices set forth below. The redemption price, expressed as a percentage of
principal amount, is as follows for the following periods:



                                                                 Redemption

    Beginning on October 18, 2004 and ending on October 14, 2005   101.50%
    Beginning on October 15, 2005 and ending on October 14, 2006   100.75%


and thereafter equal to 100% of the principal amount.

   Teradyne will begin making annual interest payments of up to $15 million,
paid semi-annually, on the Notes commencing on April 15, 2002. The Notes are
senior unsecured obligations of Teradyne that rank equally with Teradyne's
existing and future unsecured and unsubordinated indebtedness. In the event of
a change in control by which Teradyne merges with or sells substantially all of
its assets to a third party, the holders of the Notes may be able to require
Teradyne to redeem some or all of the Notes either in discounted Teradyne
common stock or in cash.

Mortgage Notes Payable

   On December 19, 2001, Teradyne obtained a loan of approximately $45 million
in the form of a 7.5% mortgage loan maturing on January 1, 2007. This loan is
collateralized by certain Teradyne California real estate properties. Principal
payments are made according to a twenty-year amortization schedule through
December 2006, with the remaining principal due on January 1, 2007. Teradyne
began making monthly principal and interest payments of $0.4 million on
February 1, 2002.

H.  DEBT--(Continued)

   In 1983, Teradyne obtained a loan of $4.5 million from the Boston
Redevelopment Authority in the form of a 3% mortgage loan maturing March 31,
2013. This loan is collateralized by Teradyne's property at 321 Harrison
Avenue, which may, at Teradyne's option, become subordinated to another
mortgage up to a maximum of $5.0 million. Interest for the first 4 1/2 years of
the loan was capitalized up to a principal amount of $5.0 million. Since
September 30, 1987, Teradyne has been making semi-annual interest payments.

Short-term Borrowings

   The weighted average interest rates on short-term borrowings outstanding as
of December 31, 2001 and 2000 was 1.2% for both years.

J.  COMMITMENTS AND CONTINGENCIES--(Continued)

   In connection with the August 2000 acquisition of each of Herco Technology
Corp., a California company, and Perception Laminates, Inc., a California
company, a complaint was filed by the former owners of those companies on or
about September 5, 2001 naming as defendants Teradyne and two of its executive
officers. The case was originally filed in the Superior Court in San Diego
County, California, and was subsequently removed by the defendants to federal
court. An amended complaint was filed in the federal court on October 12, 2001.
On or about November 14, 2001, Teradyne and the two individual defendants filed
a motion to dismiss the amended complaint in its entirety. The federal court
granted in part and denied in part that motion to dismiss. The claims that were
dismissed were dismissed with prejudice. At the federal court's request, the
plaintiffs filed a second amended complaint on March 4, 2002 setting forth
their remaining claims. The second amended complaint alleges, among other
things, that the sale of Teradyne's common stock to the former owners violated
certain California securities statutes and common law, and that Teradyne
breached certain contractual obligations in the agreements relating to the
acquisitions. The amended complaint seeks unspecified damages, including
compensatory, consequential and punitive damages, and recovery of reasonable
attorneys' fees and costs. On March 25, 2002, Teradyne and the two individual
defendants filed their answer to the second amended complaint.

   Teradyne and two of its executive officers are named as defendants in three
purported class action complaints that were filed in the United States District
Court for the District of Massachusetts, Boston, Massachusetts, on or about
October 16, 2001, October 19, 2001 and November 7, 2001. The complaints allege,
among other things, that the defendants violated Sections 10(b) and 20(a) of
the Securities Exchange Act of 1934, by making, during the period from July 14,
2000 and October 17, 2000, material misrepresentations and omissions to the
investing public regarding Teradyne's business operations and future prospects.
The complaints seek unspecified damages, including compensatory damages and
recovery of reasonable attorneys' fees and costs.

   Teradyne disputes all of the claims above and believes they are without
merit, and intends to defend vigorously against the lawsuits. However, an
adverse resolution of any of the lawsuits could have a material adverse effect
on Teradyne's financial position or results of operations. Teradyne is not
presently able to reasonably estimate potential losses, if any, related to any
of the lawsuits and therefore has not accrued for any potential losses from the
lawsuits.

   In addition, Teradyne is subject to legal proceedings and claims that arise
in the ordinary course of business. Management does not believe these actions
will have a material adverse effect on Teradyne's financial position or results
of operations.

   In 2001, Teradyne was designated as a "potentially responsible party"
("PRP") at two clean-up sites, one in California and one in Rhode Island.
Teradyne does not believe that it has any liability for the cleanup of the
California site and has requested the state of California to remove Teradyne's
name from the list of PRPs, however, Teradyne has not as yet received a reply.
In the opinion of management, the costs associated with complying with the
clean-up of this site, if required, are not expected to have a material effect
upon the financial position or results of operations of Teradyne. With respect
to the second site, in Rhode Island, additional information is currently being
collected to better understand Teradyne's financial obligations, if any, for
its portion of the clean-up of this site.

   All options and equivalent shares related to the convertible notes
outstanding in 2001 were excluded from the calculation of diluted net loss per
share because the effect would have been antidilutive. As of December 31, 2001,
there were 16.4 million options outstanding. As of December 31, 2001, there
were 15.4 million equivalent shares related to the convertible notes shares
outstanding. For purposes of computing diluted earnings per share, weighted
average common share equivalents do not include stock options with an exercise
price that exceed the average fair market value of Teradyne's common stock.
Accordingly, options to purchase 1.5 million shares of common stock in 2000 and
0.1 million shares of common stock in 1999 were not included in the calculation
of diluted net income per share.

L.  INVENTORY PROVISIONS AND SPECIAL CHARGES--(Continued)

   During 2001, Teradyne recorded charges of $37.3 million in connection with
workforce reductions and an early retirement program. The provision for
severance and early retirement benefits was recorded in restructuring charges
and related asset impairments. There were approximately 2,900 employees
terminated in 2001 across all functional groups. Teradyne has paid $23.8
million in severance benefits during 2001. All remaining severance benefits for
the terminations in 2001 will be paid by the fourth quarter of 2002.

   During 2001, Teradyne recorded a provision of $139.7 million for excess and
obsolete inventory and for discontinued product lines. The total inventory
provision for excess and obsolete inventory, excluding the discontinued product
lines, was $105.2 million in 2001 and was principally due to the sharp decline
in incoming Semiconductor Test Systems and Connection Systems orders. During
the third quarter of 2001, Teradyne recorded a charge of $40.2 million related
to the discontinuance of its Flash 750 memory product. The Flash 750 memory
product charge included an inventory writedown of $32.3 million and the
impairment of long-lived assets directly related to the support of the Flash
memory product line of $7.9 million. During the fourth quarter of 2001,
Teradyne recorded a charge of $2.3 million for obsolete inventory due to
overlapping product lines as a result of the consummation of the GenRad
acquisition.

   During the third and fourth quarters of 2001, management concluded that
certain Connection Systems long-lived assets held for disposal were impaired as
the estimated fair value was less than the carrying value of these assets. The
impaired assets charge included a $12.0 million writedown related to a
partially completed manufacturing facility held for sale and a writedown of
$12.4 million for certain manufacturing assets that were taken out of
operations and are held for disposal. Fair value of the impaired facility was
determined by a market appraisal.

   During the fourth quarter of 2001, Teradyne recorded charges for vacated
office space under operating leases at Connection Systems and Circuit Board
Test and Inspection Systems of $3.1 million and $1.7 million, respectively.

   The table below summarizes activity relating to restructuring and other
charges:

M.  RETIREMENT PLANS

   Teradyne has defined benefit pension plans covering a majority of domestic
employees and employees of certain non U.S. subsidiaries. Benefits under these
plans are based on employees' years of service and compensation. Teradyne's
funding policy is to make contributions to the plans in accordance with local
laws and to the extent that such contributions are tax deductible. The assets
of these plans consist primarily of equity and fixed income securities. In
addition, Teradyne has an unfunded supplemental executive defined benefit plan
in the United States to provide retirement benefits in excess of levels allowed
by the Employment Retirement Income Security Act (ERISA) and the Internal
Revenue Code (the "IRC").

M.  RETIREMENT PLANS--(Continued)

   During the fourth quarter of 1999, Teradyne offered all eligible domestic
employees participating in the U.S. plan a choice: to continue to have benefits
accumulate in the U.S. plan and continue to be eligible for the then current
Savings Plan match described in "Note P: Savings Plans" or to stop accumulating
benefits in the U.S plan and be eligible for an increased match in the Savings
Plan. The accrued benefit of those employees who selected the enhanced Savings
Plan match was frozen on January 1, 2000 resulting in an insignificant
curtailment gain.

balances of plan assets and obligations are shown below (in thousands):

M.  RETIREMENT PLANS--(Continued)

   The impact of the GenRad acquisition and an early retirement program
increased the projected benefit obligation by $15.9 million. GenRad had its own
retirement plan for its employees which was merged into Teradyne's plan during
2001. In the third quarter of 2001, Teradyne provided certain employees the
option to retire early.

   The following table provides amounts recognized in the statement of
financial position as of December 31, (in thousands):

   The projected benefit obligation, accumulated benefit obligation, and fair
value of plan assets for pension plans with accumulated benefit obligations in
excess of plan assets for 2001 and 2000 were as follows:



                                                                                     2001   2000

Projected benefit obligation....................................................... $181.0  $22.2
Accumulated benefit obligation.....................................................  154.8   14.3
Fair value of plan assets for pension plans with accumulated benefit obligations in
  excess of plan assets............................................................ $115.2  $ 3.7


   An additional minimum pension liability adjustment of $22 million was
required during 2001 as the accumulated benefit obligation of $155 million
exceeded the $115 million of pension plan assets at year end. The $40 million
difference was reduced by an accrued benefit liability of $18 million resulting
in an additional minimum pension liability of $22 million.

N.  COMMON STOCK REPURCHASE PROGRAM

   Teradyne's Board of Directors has authorized the repurchase of 30.0 million
shares of Teradyne's stock on the open market. During 1999, Teradyne
repurchased 5.6 million shares at a cost of $207.8 million. During 2000,
Teradyne repurchased 3.8 million shares at a cost of $147.5 million, increasing
the cumulative shares purchased under this program through 2000 to 20.0 million
shares at an aggregate cost of $540.8 million. During 2001, Teradyne did not
repurchase any stock. Teradyne records treasury stock at its acquisition cost.

O.  STOCK BASED COMPENSATION

   Teradyne has both employee and non-employee stock option plans and an
employee stock purchase plan. Teradyne previously adopted the disclosure
requirements of SFAS No. 123, "Accounting for Stock-Based Compensation"
(SFAS 123), and as permitted by this standard, will continue to apply
Accounting Principles Board (APB) Opinion 25 and related interpretations in
accounting for its plans. Teradyne is required to disclose the pro forma net
income and net income per common share amounts as if compensation costs for
Teradyne's

Stock Option Plans

   Under its stock option plans, all of which are fixed accounting plans,
Teradyne granted options to directors, officers, certain employees, and other
individuals entitling them to purchase common stock at 100% of the fair market
value on the date of grant. Options granted to employees prior to 2001 vest in
equal installments over four years and have a maximum term of five years.
Beginning in September 2001 options granted to employees also vest in equal
installments over four years but have a maximum term of seven years. In 2001,
Teradyne had a one-time option grant for all employees that vests over two
years and has a term of seven years.

Employee Stock Purchase Plan

   Under the Teradyne Employee Stock Purchase Plan, eligible employees may
purchase shares of common stock through regular payroll deductions of up to 10%
of their compensation. The price paid for the common stock is equal to 85% of
the lower of the fair market value of Teradyne's common stock on the first
business day in January (July for new hires) or the last business day of
December. In January 2002, Teradyne issued 0.9 million shares of common stock
to employees who participated in the plan during 2001 at a weighted-average
price of $25.60 per share. Currently, there are 0.4 million shares reserved for

P.  SAVINGS PLANS

   Teradyne sponsors an employee retirement Savings Plan covering substantially
all U.S. employees. Under Teradyne's savings plan, employees may contribute up
to 15% of their compensation (subject to Internal Revenue Service limitations).
For employees that elected in 1999 to continue to accrue benefits under
Teradyne's defined benefit plan, as described in "Note M: Retirement Plans,"
Teradyne annually matches employee contributions up to 6% of such compensation
at rates ranging from 50% to 100%. Employees that elected in 1999 to stop
accruing benefits under Teradyne's defined benefit plan, as described in "Note
M: Retirement Plans," are eligible for an increased Teradyne match of 100% to
150% on employee contributions up to 5% of compensation. Teradyne's
contributions vest after two years, although contributions for those employees
with five years of service vest immediately. Teradyne has also established an
unfunded Supplemental Savings Plan to provide savings benefits in excess of
those allowed by ERISA and the IRC. The provisions of this plan are the same as
the Savings Plan. Under Teradyne's savings plans, amounts charged to operations
were $14.6 million in 2001, $16.6 million in 2000, and $9.8 million in 1999.

Q.  STOCKHOLDER RIGHTS PLAN

   Teradyne's Board of Directors adopted a Stockholder Rights Plan on November
16, 2000, under which a dividend of one Common Stock Purchase Right (each a
"Right") was distributed for each outstanding share of Common Stock. The plan
entitles Right holders to purchase shares of Teradyne's common stock for $540
per share subject to adjustment (the "Purchase Price") in certain events, such
as a tender offer to acquire 20% or more of Teradyne's outstanding shares.
Under some circumstances, such as a determination by continuing Directors that
an acquiring party's interests are adverse to those of Teradyne, the Plan
entitles such holders (other than an acquiring party or adverse party) to
purchase Common Stock (or other securities or consideration owned by Teradyne)
having a value equal to two times the Purchase Price of the Right for the
Purchase Price. The Rights expire on November 27, 2010.

   At December 31, 2001 Teradyne had U.S. Federal operating loss carryforwards
of approximately $113.5 million primarily due to the operating loss
carryforwards related to the GenRad acquisition that expire in the years 2003
through 2020, state operating loss carryforwards of $88.5 million that expire
in the years 2006 through 2021, and foreign operating loss carryforwards of
$9.6 million. These losses are limited in their use by "change in ownership"
rules as defined in the Internal Revenue Code of 1986.

   Teradyne believes that it is more likely than not that its net deferred tax
assets will be realized.

   Teradyne has approximately $33.9 million of tax credit carryforwards that
expire in years 2003 through 2019. Business tax credits of approximately $24.1
million expire in the years 2003 through 2019. Foreign tax credits of
approximately $7.7 million expire in the years 2005 through 2006. Alternative
minimum tax credits of $2.1 million do not expire.

1999 follows:

S.  OPERATING SEGMENT AND GEOGRAPHIC INFORMATION

   Teradyne has four principal operating segments which are the design,
manufacturing and marketing of Semiconductor Test Systems, Connection Systems,
Circuit Board Test and Inspection Systems, and Other Test Systems. These
operating segments were determined based upon the nature of the products and
services offered. The Other Test Systems segment in 2001 is comprised of
Broadband Test Systems and Diagnostic Solutions. In 2000 and 1999, the Other
Test Systems segment is comprised of Broadband Test Systems and Software Test
Systems.

   Teradyne evaluates performance based on several factors, of which the
primary financial measure is business segment income before taxes. The
accounting policies of the business segments are the same as those described in
"Note B: Accounting Policies." Intersegment sales are accounted for at fair
value as if sales were to third parties. During 2001 and 2000 no individual
customer accounted for more than 10% of consolidated net sales. During 1999,
principally all of Teradyne's operating segments reported sales to one customer
accounting for a total of 11% of consolidated net sales.

(1) Income before taxes of the principal businesses exclude the effects of
    employee profit sharing, management incentive compensation, other
    unallocated expenses, and net interest and other income.

(2) Total business assets are directly attributable to each business. Corporate
    assets consist of cash and cash equivalents, marketable securities,
    unallocated fixed assets of support divisions and common facilities and
    certain other assets.

(3) Corporate property additions and depreciation and amortization expense
    include items attributable to the unallocated fixed assets of support
    divisions and common facilities.

(4) Corporate adjustment reflects the impact of SAB 101 on sales, income before
    taxes, and total assets in 2000. During the fourth quarter of 2000 Teradyne
    implemented SAB 101. Segments reflect their results before the change in
    accounting principle.

(1) Sales are attributable to geographic areas based on location of customer
    site.

   Because a substantial portion of Teradyne's sales are derived from the sales
of product manufactured in the United States, long-lived assets located outside
the United States are less than 10% of total assets.
