Products

Semiconductor Test

We design, manufacture, sell and support Semiconductor Test products and services on a world wide basis. The test systems we provide are used both for wafer level and device package testing. These chips are used in automotive, communications, consumer, computer and electronic game applications, among others. Semiconductor devices span a broad range of functionality, from very simple low-cost devices such as appliance microcontrollers, operational amplifiers or voltage regulators to complex digital signal processors, microprocessors, high-density as well as high speed memory devices. Semiconductor Test products and services are sold to Integrated Device Manufacturers (“IDMs”) that integrate the fabrication of silicon wafers into their business, “Fabless” companies that outsource the manufacturing of silicon wafers, “Foundries” that cater to the processing and manufacturing of silicon wafers, and outsourced semiconductor assembly and test companies (“OSATs”) that provide test and assembly services for the final packaged devices to both Fabless companies and IDMs. Fabless companies perform the design of integrated circuits without manufacturing capabilities, and use Foundries for wafer manufacturing and OSATs for test and assembly. These customers obtain the overall benefit of both comprehensively testing devices and reducing the total costs associated with testing by using our Semiconductor Test systems to:

• improve and control product quality;

• measure and improve product performance;

• reduce time to market; and

• increase production yields.

Our FLEX Test Platform Architecture advances our core technologies to produce test equipment that is designed for high efficiency multi-site testing. Multi-site testing involves the simultaneous testing of many

3

devices and functions in parallel. Leading semiconductor manufacturers are using multi-site testing to significantly improve their “Cost of Test” economics. The FLEX Test Platform architecture addresses customer requirements through the following key capabilities:

1) A high efficiency multi-site architecture that eliminates tester overhead such as instrument setup, synchronization and data movement, and signal processing;

2) The IG-XL™ software operating system which provides fast program development, including instant conversion from single to multi-site test; and

3) Broad technology coverage by instruments designed to cover the range of test parameters, coupled with a Universal Slot test head design that allows easy test system reconfiguration to address changing test needs.

FLEX Test Platform purchases are being made by IDMs, OSATs and Fabless customers. The FLEX Test Platform has become a widely used test solution at OSATs and test houses by providing versatile testers that can handle the widest range of devices, allowing OSATs to leverage their capital investments. The broad consumer, automotive and broadband markets have historically driven most of the device volume growth in the semiconductor industry. These markets include cell phones, set top boxes, HDTVs, game controllers, computer graphics, and automotive controllers to name a few. These end use markets are continuing to be drivers for the FLEX Test Platform family of products because they require a wide range of technologies and instrument coverage. The FLEX Test Platform has an installed base of more than 2,000 customer systems to date and it continues to grow.

Our J750™ test system shares the IG-XL software environment with the family of FLEX Test Platform systems. The J750 is designed to address the highest volume semiconductor devices such as microcontrollers that are central to the functionality of almost every consumer electronics product, from small appliances to automotive engine controllers. J750 test systems combine compact packaging, high throughput and ease of production test. These benefits are possible due to the high level of integration in the design. A single circuit board in the J750 test system provides up to 64 digital input/output channels. We extended the J750 platform technology to create the IP750 Image Sensor™ test system. The IP750 is focused on testing image sensor devices used in digital cameras and other imaging products. The J750 platform has an installed base of over 2,900 systems and it continues to grow.

We have continued to invest in the J750 platform with a set of J750Ex™ instrumentation that was released in 2007, with additional instrument releases in 2008. These instruments are bringing new capabilities to existing market segments and expanding the J750 platform to critical new devices that include high end microcontroller, LCD drivers, and the latest generation of cameras. These new J750Ex instruments are designed to be compatible with our customer’s existing hardware and software investments and deliver industry leading parallel test economics while providing customers with flexibility to address next generation functional requirements.

Our acquisition of Nextest in January of 2008 expanded our product offerings to include the Magnum test platform. The Magnum products address the requirements of mass production test of memory devices such as flash memory and dynamic random access memory (DRAM). Flash and DRAM memory are widely used core building blocks in modern electronic products finding wide application in consumer, industrial, and computing equipment. Magnum II is the newest member of the family. With test rates up to 800 megabits per second and a versatile architecture designed for maximal throughput, Magnum II tests both flash and DRAM devices, an important advantage for large memory producers that manufacture both types of memory. The Magnum platform has an installed base of over 650 systems and it continues to grow.

Our acquisition of Eagle Test in November of 2008 expanded our product offerings to include the ETS platform. The ETS platform is used by semiconductor manufacturers and assembly and test subcontractors, primarily in the low pin count analog/mixed signal discrete markets that cover more cost sensitive applications. Eagle Test’s proprietary SmartPin™ technology enables multiple semiconductor devices to be tested simultaneously, or in parallel, on an individual test system, permitting greater test throughput. Semiconductors

4

tested by Eagle Test’s systems are incorporated into a wide range of products in historically high-growth markets, including digital cameras, MP3 players, cellular telephones, video/multimedia products, automotive electronics, computer peripherals, and notebook and desktop computers. The ETS platform has an installed base of over 1,800 systems and it continues to grow.

Systems Test Group

Our Systems Test Group segment is comprised of 3 business units: Mil/Aero, Commercial Board Test and Diagnostic Solutions.

Mil/Aero Test

Our expertise in the test and diagnosis of printed circuit boards (“PCB”) and subsystems has proven to be essential in supporting the ever-demanding military, defense and aerospace markets. Our test solutions for these markets include high-performance systems, instruments and software solutions that manufacturers and repair depots depend on to ensure the readiness of commercial and military electronic systems.

New programs from tactical aircraft to missile systems, as well as widespread enhancement programs, continue to fuel the demand for high performance test systems. We are a leading provider of test instrumentation and systems with performance well suited to the demands of military/aerospace electronics manufacturers and repair depots worldwide. Success in this market is illustrated by our penetration into major Department of Defense programs across all U.S. military service branches and many allied military services worldwide.

Commercial Board Test

We also produce a variety of test and inspection systems sold to many of the industry’s leading PCB original equipment manufacturers (“OEMs”) and Subcons around the world. Because today’s PCBs and electronic assemblies handle more functionality than ever before, they contain highly integrated circuits and more complex components that operate faster, use lower voltages and are more susceptible to assembly problems. Our assembly test and inspection systems combine the advanced diagnostic hardware and operating software needed to ensure product quality, sustain high manufacturing yield, verify functional operation, diagnose faults and effectively reduce manufacturing costs. Our products are sold to the electronics manufacturers of cell phones, servers, computers, Internet switches, automobiles and military avionics systems worldwide.

In-Circuit Test Systems

We manufacture in-circuit test (“ICT”) systems that are used to assess electrical interconnections, verify interoperation and find faulty circuits aboard fully assembled and soldered PCBs. Fast, accurate and cost-effective diagnostic capabilities are hallmark features of our ICT systems, including the TestStation™ and Spectrum™ product families used in a variety of in-line, high-volume PCB test applications. These systems are also used in sample test environments for prototype testing and early-stage PCB design and development. Supporting technologies such as our patented SafeTest™ technology allow TestStation users to safely troubleshoot the low-voltage components and interconnects commonly found in battery-powered portable consumer electronics and low-power commercial equipment. In addition to standard ICT equipment, we offer combinational test platforms and handler-ready in-line test systems for high-volume board manufacturing.

Imaging Inspection Systems

We manufacture automated x-ray inspection (“AXI”) machines that are used to test PCB assemblies. These machines use patented technologies to quickly and automatically inspect the solder joints of the components on the board. Using x-rays allows our XStation™ MX to inspect joints that are on either side of the PCB assembly,

5

or that are hidden by the component packages themselves. The XStation MX uses ClearVue™, a patented three-dimensional X-Ray imaging technique, to more accurately detect subtle defects and manufacturing flaws, even as board complexities grow.

Diagnostic Solutions

We provide electronic test and diagnostic systems to the automotive OEMs and their major subcontractors. The systems are used throughout the vehicle’s lifecycle from design through manufacture to after sale service and consist of highly integrated software and hardware components. As the number and complexity of electronic systems and embedded software proliferate in vehicles, the ability to manufacture and service those vehicles becomes increasingly dependent on electronic diagnostic equipment. Our Diagnostic Solutions’ products fall into two categories:

OEM Service Diagnostics

OEM dealer service technicians use our systems to find faults in vehicles in use by their customers, and to reduce OEM warranty costs. Historically, the focus has been on fixing faults in the service bay, but is now growing to include the programming of vehicle software.

Vehicle Configuration and Test Solutions

Our VCATS™ products are used on automotive and major automotive subassembly production lines. These products connect to the vehicle to test and program or “configure” the electronic systems on vehicles. These vehicle electronic systems include engine control modules and subsystems such as braking, navigation and climate control. Our VCATS products are also able to link to an OEM’s manufacturing control system in order to provide statistical quality reports to operators and management.

Both VCATS and OEM Service Diagnostics products utilize our GRADE-X™ authoring software enabling the manufacturing and service phases of vehicle development. Diagnostics for electronic modules and systems used on vehicles of our customers can be developed and written using the GRADE-X authoring software. The actual diagnosis of a customer’s vehicle occurs in the OEM dealer’s service bay utilizing a runtime portion of the software to facilitate the service and repair of the vehicle.

Discontinued Operations

On August 1, 2007, our Broadband Test Division business was sold to Tollgrade Communications, Inc. This business provided test systems for testing lines and qualifying lines for DSL telephone networks. Broadband Test Division has been reflected as discontinued operations in the accompanying financial statements. On November 30, 2005, our Connection Systems business was sold to Amphenol Corporation. This business designed and manufactured high-performance connection systems including backplane systems, printed circuit boards and high-speed, high-density connectors. Connection Systems and Broadband Test Division have been reflected as discontinued operations in the accompanying financial statements.

See also “Item 1A: Risk Factors” and “Note S: Operating Segment and Geographic Information” in Notes to Consolidated Financial Statements.

Competition

We face significant competition throughout the world in each of our reportable segments. These competitors include, among others, Advantest Corporation, Verigy Inc. and LTX–Credence Corporation. Some of our competitors have substantially greater financial and other resources to pursue engineering, manufacturing, marketing and distribution of their products. We also face competition from internal suppliers at several of our customers. Some of our competitors have introduced or announced new products with certain performance characteristics which may be considered equal or superior to those we currently offer. We expect our 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. See also “Item 1A: Risk Factors.”

Backlog

At December 31, 2008 and 2007, our backlog of unfilled orders in our two reportable segments was as follows:

	2008		2007
	(in millions)
Semiconductor Test	$	129.4	$	236.2
Systems Test Group		106.9		102.5
	$	236.3	$	338.7

7

Of the backlog at December 31, 2008, approximately 89% of the Semiconductor Test backlog and 84% of Systems Test Group backlog is expected to be delivered in 2009.

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, our 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 our business, financial condition, and results of operations.

Raw Materials

Our products contain electronic and mechanical components that are provided by a wide range of suppliers. Certain of these components are standard products, while others are manufactured to our specifications. We can experience occasional delays in obtaining timely delivery of certain items. While the majority of our components are available from multiple suppliers, certain items are obtained from sole sources. We may experience a temporary adverse impact if any of our sole source suppliers’ delays or ceases to deliver products.

Intellectual Property and Licenses

The development of our products, both hardware and software, is based in significant part on proprietary information, our brands and technology. We protect our rights in proprietary information, brands and technology through various methods, such as:

• patents;

• copyrights;

• trademarks;

• trade secrets;

• standards of business conduct and related business practices; and

• technology license agreements, software license agreements, non-disclosure agreements, employment agreements, and other agreements.

However, these protections might not be effective in all circumstances. Competitors might independently develop similar technology or exploit our proprietary information and our brands in countries where we lack enforceable intellectual property rights or where enforcement of such rights through the legal system provides an insufficient deterrent. Also, intellectual property protections can lapse or be invalidated through appropriate legal processes. We do not believe that any single piece of intellectual property or proprietary rights is essential to our business.

Employees

As of December 31, 2008, we employed approximately 3,800 people. Since the inception of our business, we have experienced no work stoppages or other labor disturbances. We have no collective bargaining contracts.

Engineering and Development Activities

The highly technical nature of our products requires a large and continuing engineering and development effort. Engineering and development expenditures for the years ended December 31, 2008, 2007 and 2006 were $216.5 million, $204.3 million, and $202.4 million, respectively. These expenditures amounted to approximately 20%, 19%, and 15% of consolidated net revenue in 2008, 2007, and 2006, respectively.

8

Environmental Affairs

We are subject to various federal, state, and local government laws and regulations relating to the protection of employee health and safety and the environment. We accrue for all known environmental liabilities when it becomes probable that we will incur cleanup costs and those costs can reasonably be estimated. The amounts accrued do not cover sites that are in the preliminary stages of investigation. Estimated environmental costs are not expected to materially affect the financial position or results of our operations in future periods. However, estimates of future costs are subject to change due to protracted cleanup periods and changing site conditions and environmental remediation laws and regulations.

CEO Certification

An annual CEO certification was filed with the New York Stock Exchange on May 23, 2008 in accordance with its listing standards.

Item 1A: Risk Factors.

Risks Associated with Our Business

The risks described below are not the only risks that we face. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition and/or operating results.

Our business is impacted by worldwide economic cycles, which are difficult to predict.

Capital equipment providers in the electronics and semiconductor industries, such as Teradyne, have, in the past, been negatively impacted by sudden slowdowns in the global economies, and resulting reductions in customer capital investments. The duration of slowdowns in customer capital investments are difficult to predict.

The global economy and financial markets have been experiencing extreme disruption in recent months, including, among other things, extreme volatility in security prices, severely diminished liquidity and credit availability, rating downgrades of certain investments and declining valuations of others. Governments have taken historic actions intended to address extreme market conditions that include severely restricted credit. There may be a further deterioration in financial markets and confidence in major economies. We are unable to predict the likely duration and severity of the current disruptions in financial markets, credit availability, and adverse economic conditions throughout the world. These economic developments affect businesses such as ours and those of our customers and vendors in a number of ways that could result in unfavorable consequences to us. Further disruption and deterioration in economic conditions may further reduce customer purchases of our products, thereby reducing our revenues and earnings. In addition, such adverse economic conditions may, among other things, result in increased price competition for our products, increased risk of excess and obsolete

10

inventories, increased risk in the collectability of our accounts receivable from our customers, increased risk in potential reserves for doubtful accounts and write-offs of accounts receivable, and higher operating costs as a percentage of revenues. We are taking actions to address the effects of the current economic crisis, including implementing cost control and reduction measures, such as the reduction in force we announced on January 28, 2009. It is possible that we may experience difficulties in successfully implementing these cost controls and reduction measures in a timely manner or at all, and that we may experience delays and unexpected costs and expenses in implementing the reduction plan. Because of these and other factors, we cannot predict whether these cost control and reduction measures will be sufficient to offset certain of the negative trends that might affect our business.

Our business is dependent on the current and anticipated market for electronics, which historically has been highly cyclical.

Our 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. As evidenced by our current business and results of operations, the market demand for electronics is impacted by economic slowdowns. Historically, the electronics 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 we manufacture and market. We believe that the markets for newer generations of electronic products such as those that we manufacture and market will also be subject to similar fluctuations. We are dependent on the timing of orders from our customers, and the deferral or cancellation of previous customer orders could have an adverse effect on our results of operations. We cannot assure that the level of revenues 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 our business, financial condition and operating results. The current economic environment has adversely affected our business, financial condition and operating results. We are actively taking steps to minimize the impact of this downturn but we cannot be certain those steps will have the desired impact, or of how long the downturn will continue and when our results will improve, if at all.

We are subject to intense competition.

We face significant competition throughout the world in each of our reportable segments. Some of our competitors have substantial financial and other resources to pursue engineering, manufacturing, marketing and distribution of their products. We also face competition from internal suppliers at several of our customers. Some of our competitors have introduced or announced new products with certain performance characteristics which may be considered equal or superior to those we currently offer. We expect our 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 revenues or loss of market acceptance of our products. Moreover, increased competitive pressure could lead to intensified price based competition, which could materially adversely affect our business, financial condition and results of operations.

Our operating results are likely to fluctuate significantly.

Our operating results are affected by a wide variety of factors that could materially adversely affect revenues and profitability.

The following factors are expected to impact future operations:

• the current worldwide economic slowdown and extreme disruption in the global financial markets;

• competitive pressures on selling prices;

• our ability to introduce, and the market acceptance of, new products in 2009 and beyond;

• changes in product revenue mix resulting from changes in customer demand;

11

• the level of orders received which can be shipped in a quarter because of the tendency of customers to wait until late in a quarter to commit to purchase due to capital expenditure approvals and constraints occurring at the end of a quarter, or the hope of obtaining more favorable pricing from a competitor seeking the business;

• engineering and development investments relating to new product introductions in 2009 and beyond, and the expansion of manufacturing, outsourcing and engineering operations in Asia;

• provisions for excess and obsolete inventory relating to the lack of demand for and the discontinuance of products;

• impairment charges for certain long-lived and intangible assets and goodwill. For example in 2008, we recorded a goodwill impairment charge of $333.3 million;

• parallel or multi-site testing could lead to a decrease in the ultimate size of the market for our products; and

• the ability of our suppliers and subcontractors to meet product quality or delivery requirements needed to satisfy customer orders for our products, especially if product demand increases rapidly.

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

We are subject to risks of operating internationally.

A significant portion of our total revenue is derived from customers outside the United States. Our international sales and operations are subject to significant risks and difficulties, including:

• unexpected changes in legal and regulatory requirements affecting international markets;

• changes in tariffs and exchange rates;

• social, political and economic instability, acts of terrorism and international conflicts;

• difficulties in protecting intellectual property;

• difficulties in accounts receivable collection;

• cultural differences in the conduct of business;

• difficulties in staffing and managing international operations; and

• compliance with customs regulations.

In addition, an increasing portion of our products and the products we purchase from our suppliers are sourced or manufactured in foreign locations, including China, and a large portion of the devices our products test are fabricated and tested by foundries and subcontractors in Taiwan, Singapore, China and other parts of Asia. As a result, we are subject to a number of economic and other risks, particularly during times of political or financial instability in these regions. Disruption of manufacturing or supply sources in these international locations could materially adversely impact our ability to fill customer orders and potentially result in lost business.

If we fail to develop new technologies to adapt to our customers’ needs and if our customers fail to accept our new products, our revenues will be adversely affected.

We believe that our technological position depends primarily on the technical competence and creative ability of our engineers. In a rapidly evolving market, such as ours, the development of new technologies, commercialization of those technologies into products and market acceptance and customer demand for those products are critical to our success. Successful product development, introduction and acceptance depend upon a number of factors, including:

• new product selection;

• ability to meet customer requirements;

12

• development of competitive products by competitors;

• timely and efficient completion of product design;

• timely and efficient implementation of manufacturing and manufacturing processes;

• timely remediation of product performance issues, if any, identified during testing;

• assembly processes and product performance at customer locations;

• differentiation of our products from our competitors’ products;

• management of customer expectations concerning product capabilities and product life cycles;

• ability to attract and retain technical talent; and

• innovation that does not infringe on the intellectual property rights of third parties.

If our suppliers do not meet product or delivery requirements, we could have reduced revenues and earnings.

Certain components, including semiconductor chips, may be in short supply from time to time because of high industry demand or the inability of some vendors to consistently meet our quality or delivery requirements. Approximately 30% of material purchases require some custom work where having multiple suppliers would be cost prohibitive. If any of our suppliers were to cancel contracts or commitments or fail to meet the quality or delivery requirements needed to satisfy customer orders for our products, we could lose time-sensitive customer orders and have significantly decreased revenues and earnings, which would have a material adverse effect on our business, results of operations and financial condition. In addition, we rely on contract manufacturers for certain subsystems used in our products, and our ability to meet customer orders for those products depends upon the timeliness and quality of the work performed by these subcontractors, over whom we do not exercise any control.

To a certain extent, we are dependant upon the ability of our suppliers and contractors to help meet increased product or delivery requirements. Many of our suppliers have implemented cost reduction strategies, just as we have, to address the slowdowns in the market. It may be difficult for these suppliers to meet delivery requirements in a period of rapid growth, therefore impacting our ability to meet our customers’ demands.

We rely on the financial strength of our suppliers. There can be no assurance that the loss of suppliers either as a result of financial viability, bankruptcy or otherwise will not have a material adverse effect on our business, results of operations or financial condition.

Our operations may be adversely impacted if our outsourced contract manufacturers or service providers fail to perform.

We depend on Flextronics International Ltd. (“Flextronics”) to manufacture and test our FLEX and J750 family of products from its facility in China. If for any reason Flextronics cannot provide us with these products in a timely fashion, or at all, we may not be able to sell these products to our customers until we enter a similar arrangement with an alternative contract manufacturer. If we experience a problem with our supply of products from Flextronics, it may take us significant time to either manufacture the product or find an alternate contract manufacturer, which could result in substantial expense and disruption to our business.

We have also outsourced a number of our general and administrative functions, including information technology, to reputable service providers, many of which are in foreign countries, sometimes impacting communication with them because of language and time difficulties. Their presence in foreign countries also increases the risk they could be exposed to political risk. Additionally, there may be difficulties encountered in coordinating the outsourced operations with existing functions and operations. If we fail in successfully coordinating and managing the outsourced service providers, it may cause an adverse affect on our operations which could result in a decline in our stock price.

13

We may not fully realize the benefits of our acquisition of Nextest Systems Corporation, Eagle Test Systems, Inc., and other businesses that we may acquire or strategic alliances that we may form in the future.

In January 2008, we acquired Nextest Systems Corporation, and in November 2008, we acquired Eagle Test Systems, Inc. We may continue to acquire additional businesses, form strategic alliances or create joint ventures with third parties that we believe will complement or augment our existing businesses. We may not be able to realize the expected synergies and cost savings from the integration with our existing operations of Nextest Systems Corporation, Eagle Test Systems, Inc. and other businesses or technologies that we may acquire. In addition, the integration process for our acquisitions may be complex, costly and time consuming and include unanticipated issues, expenses and liabilities. We may have difficulty in developing, manufacturing and marketing the products of a newly acquired company in a manner that enhances the performance of our combined businesses or product lines and allows us to realize value from expected synergies. We cannot assure you that, following an acquisition, we will achieve the revenue or net income levels that justify the acquisition. Acquisitions may also result in one-time charges (such as acquisition-related expenses, write-offs or restructuring charges) or in the future, impairment of goodwill, that adversely affect our operating results. Additionally we may fund acquisitions of new businesses, strategic alliances or joint ventures by utilizing our cash, raising debt, issuing shares of our common stock, or by other means.

We may need additional financing, which could be difficult to obtain.

We expect, based upon our current estimate of our revenue and operating results for fiscal year 2009, that our cash, cash equivalents and marketable securities balance of $374.3 million will be sufficient to meet our cash requirements for the next twelve months. If our estimates of revenue and operating results for fiscal year 2009 significantly decrease, we could be required to obtain additional financing. However, if financing is necessary, we cannot be certain that we will be able to obtain such financing or that the terms will be acceptable to us. In addition, financings may place restrictions on how we operate our business. If we cannot raise funds on acceptable terms, if and when needed, we may not be able to develop or enhance our products and services, take advantage of future opportunities, grow our business or respond to competitive pressures, which could adversely harm our business.

Restrictive covenants in the agreement governing our senior credit facility may restrict our ability to pursue business strategies.

The agreement governing our senior credit facility limits our ability, among other things, to: incur additional indebtedness; sell, transfer, license or dispose of assets; consolidate or merge; enter into transactions with our affiliates; and incur liens. In addition, our senior credit facility contains financial and other restrictive covenants that limit our ability to engage in activities that may be in our long term best interest, such as, subject to permitted exceptions, making capital expenditures in excess of certain thresholds, making investments, loans and other advances, and prepaying our other indebtedness while our indebtedness under our senior credit facility is outstanding. Our failure to comply with financial and other restrictive covenants could result in an event of default, which if not cured or waived, could result in the lenders requiring immediate payment of all outstanding borrowings or foreclosing on collateral pledged to them to secure the indebtedness.

We have taken measures to address slowdowns in the market for our products, which could have long-term negative effects on our business or impact our ability to adequately address a rapid increase in customer demand.

We have taken, and continue to take, measures to address slowdowns in the market for our products. These measures include shifting more of our operations to lower cost regions, outsourcing manufacturing processes, divesting of certain businesses, implementing material cost reduction programs, reducing both the number of our employees and the compensation paid to our employees, and reducing planned capital expenditures and expense budgets. We cannot assure that the measures we have taken will not impair our ability to effectively develop and market products, to remain competitive in the industries in which we compete, to operate effectively, to operate

14

profitably during slowdowns or to effectively meet a rapid increase in customer demand. These measures may have long-term negative effects on our business by reducing our pool of technical talent, decreasing or slowing improvements in our products, making it more difficult to hire and retain talented individuals and to quickly respond to customers or competitors in an upward cycle.

We may incur significant liabilities if we fail to comply with environmental regulations.

We are subject to both domestic and international environmental regulations and statutory strict liability relating to the use, storage, discharge, site cleanup and disposal of hazardous chemicals used in our manufacturing processes. If we fail to comply with present and future regulations, or are required to perform site remediation, we could be subject to future liabilities or costs, including penalties or the suspension of production. Present and future regulations may also:

• restrict our ability to expand facilities;

• restrict our ability to ship certain products into the European Union or elsewhere;

• require us to modify our operations logistics;

• require us to acquire costly equipment; or

• require us to incur other significant costs and expenses.

Pursuant to present regulations and agreements, we are conducting groundwater and subsurface assessment and monitoring and are implementing remediation and corrective action plans for facilities located in California, Massachusetts and New Hampshire which are no longer conducting manufacturing operations. As of December 31, 2008, we have not incurred material costs as result of the monitoring and remediation steps taken at the California, Massachusetts and New Hampshire sites.

On January 27, 2003, the European Union adopted the following directives: (i) the directive on the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment (the “RoHS Directive”); and (ii) the directive on Waste Electrical and Electronic Equipment (the “WEEE Directive”). The WEEE Directive became effective August 13, 2005 and the RoHS Directive became effective on July 6, 2006. Both the RoHS Directive and the WEEE Directive alter the form and manner in which electronic equipment is imported, sold and handled in the European Union. Other jurisdictions, such as China, have followed the European Union’s lead in enacting legislation with respect to hazardous substances and waste removal. Ensuring compliance with the RoHS Directive, the WEEE Directive and similar legislation in other jurisdictions, and integrating compliance activities with our suppliers and customers could result in additional costs and disruption to operations and logistics and thus could have a negative impact on our business, operations and financial condition.

We currently are and in the future may be subject to litigation that could have an adverse effect on our business.

From time to time, we may be subject to litigation or other administrative and governmental proceedings that could require significant management time and resources and cause us to incur expenses and, in the event of an adverse decision, pay damages in an amount that could have a material adverse effect on our financial position or results of operations.

For example, in connection with our August 2000 acquisition of each of Herco Technology Corp. and Perception Laminates, Inc., a complaint was filed on or about September 5, 2001 by the former owners of those companies naming as defendants Teradyne and two of our then executive officers. Additionally, in 2001, we were designated as a “potentially responsible party” at a clean-up site in Los Angeles, California and in 2008 we were notified of potential liability relating to contamination at a disposal site in West Covina, California. Both of these claims also arise out of our acquisition of Perception Laminates in August 2000. Prior to that date, Perception Laminates had itself acquired certain assets of Alco Industries Inc. under an asset purchase agreement dated October 20, 1992. These matters are further described in “Item 3: Legal Proceedings.”

15

Third parties may claim we are infringing their intellectual property and we could suffer significant litigation costs, licensing expenses or be prevented from selling our products.

We receive notifications from time to time that we may be in violation of patents held by others. In October 2008, we were served with patent infringement litigation from Xyratex Technology Ltd (“Xyratex”). The Xyratex matter is further described in “Item 3: Legal Proceedings.” An assertion of patent infringement against us such as the Xyratex suit, if successful, could have a material adverse effect on our ability to sell our new hard disk drive testing product or it could force us to seek a license to the intellectual property rights of others or alter such product so that they no longer infringe the intellectual property rights of others. A license could be very expensive to obtain or may not be available at all. Similarly, changing our products or processes to avoid infringing the rights of others may be costly or impractical. Additionally, patent litigation, such as the Xyratex suit, could require a significant use of management resources and involve a lengthy and expensive defense, even if we eventually prevail. If we do not prevail, we might be forced to pay significant damages, obtain licenses, modify our products, or stop making our products; each of which could have a material adverse affect on our financial condition and operating results.

We have significant guarantees and indemnification obligations.

From time to time we make guarantees to customers regarding the performance of our products and guarantee certain indebtedness, performance obligations or lease commitments of our subsidiary and affiliate companies. We also have agreed to provide indemnification to our officers, directors, employees and agents, to the extent permitted by law, arising from certain events or occurrences while the officer, director, employee or agent, is or was serving at our request in such capacity. If we become liable under any of these obligations, it could materially and adversely affect our business, financial condition and operating results. For additional information see “Note K: Commitments and Contingencies—Guarantees and Indemnification Obligations” in Notes to Consolidated Financial Statements.

If we are unable to protect our intellectual property, we may lose a valuable asset or may incur costly litigation to protect our rights.

We protect the technology that is incorporated in our products (“IP”) in several ways, including through patent, copyright, and trade secret protection and by contractual agreement. However, even with these protections, our IP may still be challenged, invalidated or subject to other infringement actions. While we believe that our IP has value in the aggregate, no single element of our IP is in itself essential. If a significant portion of our IP is invalidated or ineffective, our business could be materially adversely affected. In addition, we receive notifications from time to time that we may be in violation of patents held by others. An assertion of patent infringement against us, if successful, could have a material adverse effect on our ability to sell our products, or require a significant use of management resources and necessitate a lengthy and expensive defense which could adversely affect our operating results.

Our business may suffer if we are unable to attract and retain key employees.

Competition for employees with skills we require is intense in the high technology industry. Our success will depend on our ability to attract and retain key technical employees. The loss of one or more key or other employees, a decrease in our inability to attract additional qualified employees, or the delay in hiring key personnel could each have a material adverse effect on our business, results of operations or financial condition.

Acts of war, terrorist attacks and the threat of domestic and international terrorist attacks may adversely impact our business.

Acts of war and terrorist attacks may cause damage or disruption to our employees, facilities, customers, suppliers and distributors which could have a material adverse effect on our business, results of operation or financial condition. As we, our outsourced manufacturing providers and our suppliers sell and manufacture products both in the United States and internationally, the threat of future terrorist attacks could lead to changes in security and operations at these locations which could increase our operating costs and which may adversely affect our business. Such conflicts may

16

also cause damage or disruption to transportation and communication systems. We have completed some emergency preparedness planning and have a business continuity plan in case some of these events occur. However, we cannot be certain that our plans will be effective in the event of a disaster or other situation. All of these conditions make it difficult for us, and our customers, to accurately forecast and plan future business activities and could have a material adverse effect on our business, financial condition and results of operations.

Provisions of our charter and by-laws and Massachusetts law make a takeover of Teradyne more difficult.

During 2007, we made several important corporate governance changes, which included declassification of our Board of Directors, adoption of majority voting standard for the election of our directors, and early termination of our shareholder rights plan. Despite these changes, there are still provisions in our basic corporate documents and under Massachusetts law that could discourage, delay or prevent a change in control, even if a change in control may be regarded as beneficial to some or all of our stockholders.

(a) In 2008, Teradyne sold two buildings in its North Reading, Massachusetts campus and leased back approximately 267,600 square feet. Teradyne is consolidating and relocating the operations in these building into the 3 remaining buildings on the campus. The consolidation is estimated to be complete by July of 2009.

(b) This space consists of two buildings. One building is subleased and the other is vacant.

(c) In 2008, Teradyne sold one of its buildings in Agoura Hills, California and leased back approximately 57,000 square feet.

Item 3: Legal Proceedings

On July 11, 2008, Xyratex Technology, Ltd (“Xyratex”) filed a complaint against us in the United States Federal District Court in Los Angeles, California alleging that certain of our disk drive test products infringe one of Xyratex’s patents. The complaint was served on Teradyne on October 29, 2008. The suit seeks temporary, preliminary and permanent injunctive relief as well as unspecified monetary damages, including treble damages, for patent infringement. On December 17, 2008, we filed our answer and counterclaims, denying that our disk drive test products infringe the asserted Xyratex patent and asking the court to declare such patent invalid. The case is currently in the discovery phase and trial is scheduled to begin in November 2009. We intend to vigorously defend against the Xyratex claim and to vigorously pursue our counterclaims against Xyratex.

On September 5, 2001, after our August 2000 acquisition of Herco Technology Corp. and Perception Laminates, Inc., the former owners of those companies filed a complaint against Teradyne and two of our then executive officers in the Federal District Court in San Diego, California, asserting securities fraud and breach of contract related to the acquisition. The District Court dismissed certain of the plaintiffs’ claims, granted partial summary judgment against them with respect to their breach of contract claim and denied their motion for reconsideration. In July 2007, after an appeal by the plaintiffs, the U.S. Court of Appeals for the Ninth Circuit affirmed in part and reversed in part the District Court rulings. We petitioned the Ninth Circuit for rehearing, which was denied, and the case was remanded back to the District Court. On August 29, 2008, the District Court granted Teradyne’s motion for judgment on the pleadings. On September 11, 2008, the plaintiffs filed their notice of appeal.

In 2001, we were designated as a Potentially Responsible Party (“PRP”) at a clean-up site in Los Angeles, California. This claim arose out of our acquisition of Perception Laminates in August 2000. Prior to that date, Perception Laminates had itself acquired certain assets of Alco Industries Inc. under an asset purchase agreement in 1992. Neither Teradyne nor Perception Laminates have ever conducted any operations at the Los Angeles site. We have asked the State of California to drop the PRP designation, but California has not yet agreed to do so.

In November 2008, we received a general notice letter from the California Department of Toxic Substances Control (“DTSC”) which informed us of potential liability with respect to contamination at the BKK Corporation Landfill Facility Site in West Covina, California. Similar to the PRP claim discussed above, this claim arose out of our acquisition of Perception Laminates in August 2000. Neither we nor Perception Laminates have ever conducted any operations at the West Covina site. We have asked the DTSC and the group of settling defendants to remove us as a PRP for this site.

We believe that we have meritorious defenses against the above unsettled claims and intend to vigorously contest them. While it is not possible to predict or determine the outcomes of the unsettled claims or to provide possible ranges of losses that may arise, we believe the potential losses associated with all of these actions are unlikely to have a material adverse effect on our consolidated financial position, but could possibly be material to our consolidated results of operations and of cash flows of any one period.

In addition, we are subject to legal proceedings, claims and investigations that arise in the ordinary course of business such as, but not limited to, patent, employment, commercial and environmental matters. Although there can be no assurance, there are no such matters pending that we expect to be material with respect to our business, financial position or results of operations.

The number of record holders of our common stock at February 28, 2009 was 2,650.

We have never paid cash dividends because it has been our policy to use earnings to finance expansion and growth. Payment of future cash dividends will rest within the discretion of our Board of Directors and will depend, among other things, upon our earnings, capital requirements and financial condition.

See “Item 7: Management’s Discussion and Analysis of Financial Condition and Results of Operations—Equity Compensation Plans,” for information on our equity compensation plans and our performance graph.

In November 2007, Teradyne’s Board of Directors (the “Board”) authorized a $400 million stock repurchase program. During the three months ended December 31, 2008, Teradyne did not repurchase any shares of common stock. For the year ended December 31, 2008, Teradyne repurchased 7.5 million shares of common stock for $91.2 million at an average price of $12.20 per share. The cumulative repurchases as of December 31, 2008 total 8.5 million shares of common stock for $102.6 million at an average price of $12.14 per share. As of November 4, 2008, the Board temporarily suspended the implementation of the stock repurchase program.

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 Section 21E of the Exchange Act, that involve risks and uncertainties, such as statements of our 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. Our 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 “Item 1A: Risk Factors” and elsewhere herein.

Critical Accounting Policies and Estimates

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

20

Preparation of Financial Statements and Use of Estimates

The preparation of consolidated financial statements requires management 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, management evaluates its estimates, including those related to inventories, investments, goodwill, intangible and other long-lived assets, bad debts, income taxes, pensions, warranties, contingencies, and litigation. Management 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 significantly from these estimates.

Revenue Recognition

We recognize 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. Title and risk of loss generally pass to our customers upon shipment or at delivery destination point. In circumstances where either title or risk of loss pass upon destination, acceptance or cash payment, we defer revenue recognition until such events occur.

Our equipment includes embedded software which is considered incidental to the product. Revenue is recognized upon shipment or at delivery destination point, provided that customer acceptance criteria can be demonstrated prior to shipment. Certain contracts require us to perform tests of the product to ensure that performance meets the published product specifications or customer requested specifications, which are generally conducted prior to shipment. Where the criteria cannot be demonstrated prior to shipment, revenue is deferred until customer acceptance has been received.

For multiple element arrangements we defer the fair value of any undelivered elements of the contract. We also defer the portion of the sales price that is not due until acceptance, which represents deferred profit. For a delivered item to be considered a separate unit, the delivered item must have value to the customer on a standalone basis, there must be objective and reliable evidence of fair value of the undelivered items in the arrangement and the delivery or performance of the undelivered item must be considered probable and substantially in our control. Fair value is the price charged when the element is sold separately. Our post-shipment obligations include installation, training services, one-year standard warranties, and extended warranties. Installation does not alter the product capabilities, does not require specialized skills or tools and can be performed by the customers or other vendors. Installation is typically provided within five to fifteen days of product shipment and is completed within one to two days thereafter. Training services are optional and do not affect the customer’s ability to use the product. We defer revenue for the fair value of installation and training. Extended warranties constitute warranty obligations beyond one year and we defer revenue in accordance with Financial Accounting Standards Board (“FASB”) Technical Bulletin 90-1, Accounting for Separately Priced Extended Warranty and Product Maintenance Contracts.

Our products are generally subject to warranty and related costs of the warranty are provided for in cost of revenue when product revenue is recognized. We classify shipping and handling costs in cost of revenue. Service revenue is recognized over the contractual period or as the services are performed.

We generally do not provide our customers with contractual rights of return for any of our products.

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 (“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.” We recognize revenue when there is persuasive evidence of an arrangement, delivery has occurred, the sales price is fixed or determinable and collectibility is probable. In instances where an arrangement contains multiple elements, revenue is deferred related to the undelivered elements to the extent that vendor-specific objective evidence of fair value (“VSOE”) exists for such elements. In instances where VSOE does not exist for one or more of the undelivered elements of an arrangement, all revenue related to the arrangement is deferred until all elements have been delivered. VSOE is

21

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 the percentage of incurred costs to estimated total costs. These arrangements require 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 they are determined. With respect to contract change orders, claims or similar items, judgment must be used in estimating related amounts and assessing the potential for realization. Such amounts are only included in the contract value when they can be reliably estimated and realization is reasonably assured, generally upon receipt of a customer approved change order.

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, we use consistent methodologies to evaluate all inventories for net realizable value. We record a provision for both excess and obsolete inventory when such write-downs or write-offs are identified through the quarterly review process. The inventory valuation is based upon assumptions about future demand, product mix and possible alternative uses.

Equity Incentive and Stock Purchase Plans

Effective January 1, 2006, we adopted the fair value recognition provision of Financial Accounting Standards No. 123 (revised 2004) “Share Based Payment” (“SFAS 123R”), using the modified prospective transition method and therefore have not restated results for prior periods. Under this transition method, stock based compensation expense for the first quarter of fiscal 2006 includes compensation expense for all stock-based compensation awards granted prior to, but not yet vested as of January 1, 2006, and is calculated based on the grant date fair value estimated in accordance with the original provisions of SFAS No. 123 “Accounting for Stock Based Compensation” (“SFAS 123”). Stock-based compensation expense for all stock-based compensation awards granted after January 1, 2006 is based on the grant-date fair value estimated in accordance with the provision of SFAS 123R. As required by SFAS 123R, we have made an estimate of expected forfeitures and are recognizing compensation costs only for those stock-based compensation awards expected to vest. The cumulative effect of the initial adoption of SFAS 123R was not material.

Prior to the adoption of SFAS 123R, we recognized stock-based compensation expense in accordance with Accounting Principles Board (“APB”) Opinion No. 25 (“APB 25”). In March 2005, the SEC issued Staff Accounting Bulletin No. 107 (“SAB 107”) regarding the SEC’s interpretation of SFAS 123R and the valuation of share-based payments for public companies. We have applied provisions of SAB 107 in our adoption of SFAS 123R.

On May 26, 2005, our Board of Directors approved the accelerated vesting of certain outstanding, unvested “out of the money” stock options awarded to employees, officers and other eligible participants under our various stock option plans in effect at that time. The stock options that were accelerated had exercise prices that were in excess of $13.26, the closing price of our common stock on the New York Stock Exchange on May 26, 2005 and ranged in exercise price from $13.73 to $41.37 per share. As a result of the vesting acceleration, options to purchase approximately 7.6 million shares became exercisable immediately and we reduced the compensation expense we otherwise would have been required to record under SFAS 123R by approximately $48.6 million in the aggregate on a pre-tax basis over fiscal years 2006, 2007 and 2008.

Income Taxes

On a quarterly basis, we evaluate the realizability of our deferred tax assets by jurisdiction and assess the need for a valuation allowance. As a result of this review, undertaken at December 31, 2002, we concluded under

22

applicable accounting criteria that it was more likely than not that our deferred tax assets would not be realized and established a valuation allowance in several jurisdictions, most notably the United States. Due to the continued uncertainty of realization, we have maintained our valuation allowance at December 31, 2008 and 2007.

Investments

We account for our investments in debt and equity securities in accordance with the provisions of Statement of Financial Accounting Standards No 115 “Accounting for Certain Investments in Debt and Equity Securities” (“SFAS No. 115”) and FASB Staff Position Nos. FAS 115-1 and FAS 124-1, The Meaning of Other-Than-Temporary Impairment and Its Application to Certain Investments.” On a quarterly basis we review our investments to identify and evaluate those that have an indication of a potential other-than-temporary impairment. Factors considered in determining whether a loss is other-than-temporary include:

• The length of time and the extent to which the market value has been less than cost;

• The financial condition and near-term prospects of the issuer; and

• The intent and ability to retain the investment in the issuer for a period of time sufficient to allow for any anticipated recovery in market value.

We have determined that we do not intend to hold certain marketable securities for a period of time sufficient to allow for recovery in market value and recognized an other-than-temporary impairment loss in the amount of $11.0 million, in the year ended December 31, 2008, primarily related to mortgage and asset backed debt securities.

Effective January 1, 2008, we adopted Statement of Financial Accounting Standards No. 157, “Fair Value Measurements” (“SFAS No. 157”) for financial assets and liabilities. As defined in SFAS No. 157, fair value is the price that would be received from the sale of an asset or paid to transfer a liability in an orderly transaction between market participants. We use the market and income approach techniques to value our financial instruments. SFAS No. 157 requires that assets and liabilities carried at fair value be classified and disclosed in one of the following three categories:

Level 1: Quoted prices in active markets for identical assets as of the reporting date.

Level 2: Inputs other than Level 1, that are observable either directly or indirectly as of the reporting date. For example, a common approach for valuing fixed income securities is the use of matrix pricing. Matrix pricing is a mathematical technique used to value securities by relying on the securities’ relationship to other benchmark quoted prices, and therefore is considered a Level 2 input.

Level 3: Unobservable inputs that are not supported by market data. Unobservable inputs are developed based on the best information available, which might include Teradyne’s own data.

As a result of our November 14, 2008 acquisition of Eagle Test, we acquired $26.5 million of auction rate securities (ARS) at fair value ($30.0 million par value). In addition, we acquired (1) the right (“UBS Put”) to sell our ARS back to UBS at par plus interest, at our sole discretion, during a two-year period beginning on June 30, 2010, and (2) received an option to borrow up to 75% of the fair value of the ARS at no cost.

Beginning in February 2008 and continuing through December 31, 2008, the securities in our acquired ARS portfolio have experienced failed auctions, resulting in inability to sell these securities. Consequently, as set forth in the trust indentures, the coupon rate resets to a contractual rate which may not equal the current market rate. A failed auction results in a lack of liquidity in the securities but does not necessarily represent a deterioration of the credit quality of the issuer. All of our ARS, are AAA, AA or A rated by one or more of the major credit rating

23

agencies and are substantially guaranteed by a U.S. Department of Education agency or a third party insurer. At December 31, 2008, the underlying securities for the ARS have remaining maturities ranging from five to thirty-one years. Substantially, all of these securities are collateralized by student loans. The estimated fair value of our ARS portfolio was $26.0 million as of December 31, 2008.

Because the UBS Put is expected to allow us to sell our ARS securities at par within a relatively short time horizon and provides UBS with the ability to require us to sell the securities to them at any time between acceptance of the UBS Put through July 2012, we do not anticipate holding these investments to the earlier of maturity or redemption by the issuer. We intend to exercise the UBS Put and require UBS to repurchase our ARS at par at the earliest possible time, June 2010. As a result, as of the Eagle Test acquisition date (November 14, 2008), we classified the ARS as trading securities under SFAS No. 115. During the fourth quarter of 2008, we recorded a loss of $0.5 million in interest expense and other, net in our consolidated statement of operations for the decrease in the ARS fair value from November 14, 2008 to December 31, 2008. Future changes in fair value of the ARS will be recorded in operating results.

In determining the fair value of our ARS and other investments we utilize the provisions of SFAS No. 157. In determining the value of our ARS as of December 31, 2008 we utilized a discounted cash flow valuation model with the major inputs to such model based on our estimates of the assumptions that market participants would use in valuing these instruments. Specifically, we used the following key inputs to our valuation model:

• Term — we estimated a five-year expected life of the instruments, based on our expectations of the most likely time in which it would take for the instruments to be called by the issuer or liquidity to be restored to the market place.

• Probability of Default — we determined the probability of default using market credit spreads.

• Discount Rate — we determined the discount rate based on estimated yields of similar publicly traded instruments (e.g., similar collateral, terms, credit quality, etc.).

• Liquidity Risk Premium — given the recent instability in the financial markets and the low demand for auction rate securities, it is unclear as to when these securities will become liquid again. Without the auction process functioning again, it would be extremely difficult to estimate the expected holding period for these instruments. As a result, we included a 500 to 600 basis point premium to the discount rate to reflect the illiquidity of these bonds.

Based on these key inputs, we estimated the fair value of our ARS portfolio was $26.0 million as of December 31, 2008 representing a $0.5 million decrease in fair value since November 14, 2008. Our ARS securities and the related put option were the only investments as of December 31, 2008 in which we utilized Level 3 valuation techniques under SFAS No. 157.

On November 14, 2008, we recognized the UBS Put as an asset measured at a fair value of $2.7 million. At December 31, 2008, the fair value of the UBS Put was $3.3 million. We recorded a $0.6 million gain in interest income during the fourth quarter of 2008 for the increase in the fair value of the UBS Put since November 14, 2008. In determining the fair value of the UBS Put as of December 31, 2008, we assumed we would redeem the auction rate securities at par at the earliest possible time, June 30, 2010. We utilized a discounted cash flow model to determine the fair value of the UBS Put using the following assumptions (1) a time period of 1.5 years, representing the period from December 31, 2008 to the earliest date we can expect to be able to redeem the UBS Put (June 30, 2010) and (2) a discount rate of 3.79%, which included a spread based on the credit default swap of UBS in order to account for the credit risk of UBS.

We have elected fair value treatment for the UBS Put under SFAS No. 159 “The Fair Value Option for Financial Assets and Financial Liabilities” (“SFAS No. 159”). The UBS Put is the only instrument of its nature/type that we hold and for which we have elected the fair value option under SFAS No. 159.

Goodwill, Intangible and Long-Lived Assets

We assess the impairment of identifiable intangibles, long-lived assets and goodwill whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Factors we consider important in the determination of an impairment include significant underperformance relative to historical or projected future operating results, significant changes in the manner that we use the acquired asset and significant negative industry or economic trends. When we determine that the carrying value of intangibles and long-lived assets may not be recoverable based upon the existence of one or more of the above indicators of impairment, we measure any impairment based on a projected discounted cash flow method using a discount rate commensurate with the associated risks. We assess goodwill for impairment at least annually in the fourth quarter, on a reporting unit basis, or more frequently when events and circumstances occur indicating that the recorded goodwill may be impaired. If the book value of a reporting unit exceeds its fair value, the implied fair value of goodwill is compared with the carrying amount of goodwill. If the carrying amount of goodwill exceeds the implied fair value, an impairment loss is recorded in an amount equal to that excess.

We determined that the worsening in our demand outlook experienced during the fourth quarter of 2008 was a significant event that indicated that the carrying amount of certain long-lived and intangible asset groups might not be recoverable. We conducted recoverability tests in accordance with SFAS No. 144, “Accounting for Impairment or Disposal of Long-Lived Assets” (“SFAS No. 144”). As the undiscounted future cash flows of the long-lived asset groups exceeded their carrying amount, we determined that no impairment of our long-lived assets had occurred at December 31, 2008.

Results of Operations

Discontinued Operations

On August 1, 2007, we completed the sale of the Broadband Test Division to Tollgrade for $11.3 million in cash. Broadband Test Division had revenues for the seven month period ended July 31, 2007 of $11.2 million

25

and for the year ended December 31, 2006 of $20.6 million. Loss from discontinued operations of our Broadband Test Division for the year ended December 31, 2007 was $6.3 million and loss for the year ended December 31, 2006 was $5.6 million. In 2007, we recorded a gain on the sale of Broadband Test Division of $5.9 million, net of a tax provision of $0.4 million.

In accordance with SFAS 144, we are reporting Broadband Test Division as discontinued operations in the consolidated financial statements for all periods presented throughout this Annual Report on Form 10-K. Unless indicated otherwise, the discussion and amounts provided in this “Results of Operations” section and elsewhere in this Form 10-K relate to continuing operations only.

Bookings

Net bookings for our two reportable segments were as follows:

	2008		2007		2006		2007-2008 Dollar Change			2006-2007 Dollar Change
	(in millions)
Semiconductor Test	$	768.1	$	899.7	$	1,012.6	$	(131.6	)	$	(112.9	)
Systems Test Group		211.5		208.2		270.5		3.3			(62.3	)
	$	979.6	$	1,107.9	$	1,283.1	$	(128.3	)	$	(175.2	)

The Semiconductor Test business is dependent on the current and anticipated market for test equipment, which historically has been highly cyclical. Semiconductor Test bookings decreased $131.6 million or 15% from 2007 to 2008 due primarily to lower demand across all customer groups. In 2008, Nextest contributed $67.6 million of bookings and Eagle Test contributed $1.0 million of bookings.

The Semiconductor Test bookings decreased $112.9 million or 11% from 2006 to 2007 due to lower demand across a wide range of end markets, applications and geographies, as SOC device units grew at a lower rate in 2007 than in 2006. The lower demand in SOC market was lessened by our increase in SOC market share during 2007, by approximately 2 to 3 points.

Systems Test Group bookings increased $3.3 million or 2% from 2007 to 2008, primarily due to an increase in Mil/Aero board test program related bookings partially offset by decreases in Commercial Board Test and Diagnostic Solutions.

Systems Test Group bookings decreased $62.3 million or 23% from 2006 to 2007, primarily due to decreases across all business units. Diagnostic Solutions orders are program related and have significant fluctuations. There was a large program rollout in 2006 for the Vehicle Measurement Module product line. Mil/Aero bookings are also often program related, and there was also a significant military program that took place in 2006. Commercial Board Test bookings decreased in 2007 due to a contraction in the size of the ICT market.

Order cancellations and backlog adjustments for our two reportable segments for the last three years were as follows:

	2008		2007		2006
	(in millions)
Semiconductor Test	$	10.3	$	13.6	$	3.3
Systems Test Group		—		0.3		0.5
	$	10.3	$	13.9	$	3.8

Customers may delay delivery of products or cancel orders suddenly and without significant notice, subject to possible cancellation penalties. In 2008, 2007 and 2006, there were no significant cancellation penalties received.

26

Due to possible changes in delivery schedules and cancellations of orders, our 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 our business, financial condition and results of operations.

Revenue

Net revenues for our two reportable segments were as follows:

	2008		2007		2006		2007-2008 Dollar Change			2006-2007 Dollar Change
	(in millions)
Semiconductor Test	$	900.3	$	876.5	$	1,088.9	$	23.8		$	(212.4	)

	$	1,107.0	$	1,102.3	$	1,356.2	$	4.7		$	(253.9	)

Semiconductor Test revenue increased $23.8 million or 3% from 2007 to 2008, primarily due to $79.4 million of sales from our Nextest acquisition partially offset by lower sales due to decreased demand due to SOC device units growing at a lower rate in 2008 compared to 2007.

Semiconductor Test revenue decreased $212.4 million or 20% from 2006 to 2007 due to SOC device units growing at a lower rate in 2007 compared to 2006. This resulted in decreased demand across a wide range of end markets, applications and geographies. The lower demand rate was lessened by an increase in SOC market share during 2007 by approximately 2 to 3 points.

Systems Test Group revenue decreased $19.1 million or 8% from 2007 to 2008, primarily due to a lower Mil/Aero board test program-related sales.

Systems Test Group revenue decreased $41.5 million or 16% from 2006 to 2007 due to decreased sales in Diagnostic Solutions. The decrease was related to a large program rollout for the Vehicle Measurement Module product line that took place in 2006 and was concluded in 2007.

Our two reportable segments accounted for the following percentages of consolidated net revenue for each of the last three years:

	2008		2007		2006
Semiconductor Test	81	%	80	%	80	%
Systems Test Group	19		20		20

The breakout of product and service revenue for the past three years was as follows:

	2008		2007		2006		2007-2008 Dollar Change			2006-2007 Dollar Change
	(in millions)
Product Revenue	$	836.0	$	861.6	$	1,118.8	$	(25.6	)	$	(257.2	)
Service Revenue		271.0		240.7		237.4		30.3			3.3
	$	1,107.0	$	1,102.3	$	1,356.2	$	4.7		$	(253.9	)

Our product revenue decreased $25.6 million or 3% in 2008 from 2007 due to decreased demand. Service revenue, which is derived from the servicing of our installed base of products and includes maintenance contracts, repairs, extended warranties, parts sales and applications support, increased $30.3 million or 13% due to a larger installed base.

Our product revenue decreased $257.2 million or 23% in 2007 from 2006 due to SOC device units growing at a lower rate in 2007 compared to 2006. Service revenue increased $3.3 million or 1% in 2007 from 2006.

In the past three years, no single customer accounted for more than 10% of consolidated net revenue. In 2008, 2007, and 2006, our three largest customers in the aggregate accounted for 14%, 16%, and 18% of consolidated net revenue, respectively.

Gross Profit

Percent of Total Revenue		45.0	%		46.6	%		48.1	%		(1.6	)		(1.5	)

28

Gross profit as a percentage of revenue decreased from 2007 to 2008 by 1.6 percentage points. A decrease of 2.5 points was due to a $27.6 million increase in provision for excess and obsolete inventory recorded as a result of the significant decrease in forecasted semiconductor demand coupled with a product transition; this decrease was partially offset by improved service margins in our Semiconductor Test group.

Gross profit as a percentage of revenue decreased from 2006 to 2007 by 1.5 percentage points. A reduction in Semiconductor Test sales volume contributed to a decrease of 1.5 points, a shift in product mix, primarily related to higher service revenue as a percentage of total revenue, contributed to a decrease of 2 points; these decreases were partially offset by an increase of 1 point related to lower Semiconductor Test inventory provision in 2007, and an increase of 1 point resulting from lower fixed costs and employee compensation across both segments.

The breakout of product and service gross profit was as follows:

	2008			2007			2006			2007-2008 Dollar / Point Change			2006-2007 Dollar / Point Change
	(dollars in millions)

Percent of Service Revenue		41.8	%		34.2	%		35.1	%		7.6			(0.9	)

We assess the carrying value of our inventory on a quarterly basis by estimating future demand and comparing that demand against on-hand and on-order inventory positions. Forecasted revenue information is obtained from the sales and marketing groups and incorporates factors such as backlog and future revenue demand. This quarterly process identifies obsolete and excess inventory. Obsolete inventory, which represents items for which there is no demand, is fully reserved. Excess inventory, which represents inventory items that are not expected to be consumed during the next four quarters, is written-down to estimated net realizable value.

The provision for excess and obsolete inventory included in cost of revenues for the year ended December 31, 2008 was $29.4 million. Of the $29.4 million of total excess and obsolete provisions recorded, $24.9 million was related to Semiconductor Test and $4.5 million was related to Systems Test Group.

The provision for excess and obsolete inventory included in cost of revenues for the year ended December 31, 2007 was $1.8 million. Of the $1.8 million of total excess and obsolete provisions recorded, $0.5 million related to Semiconductor Test and $1.3 million related to Systems Test Group.

The provision for excess and obsolete inventory included in cost of revenues for the year ended December 31, 2006 was $12.8 million. Of the $12.8 million of total excess and obsolete provisions recorded, $11.5 million related to Semiconductor Test (including an $8.0 million provision for the write-down of excess non-FLEX inventory) and $1.3 million related to Systems Test Group.

During the year ended December 31, 2008, 2007 and 2006 we scrapped $1.3 million, $33.5 million and $29.5 million of inventory, respectively, and sold $2.4 million, $1.1 million and $2.8 million of previously written-down or written-off inventory, respectively. As of December 31, 2008, we have inventory related reserves for amounts which had been written-down or written-off totaling $124.9 million. We have no pre-determined timeline to scrap the remaining inventory.

The increase of $12.2 million or 6% in engineering and development expenses from 2007 to 2008 was mainly due to an increase of $10.3 million in spending related to investments in adjacent markets, an increase of $12.9 million due to the acquisition of Nextest and Eagle Test, partially offset by a decrease in other Semiconductor Test spending primarily related to headcount reduction of $8.3 million and lower variable employee compensation of $2.8 million.

The increase of $1.9 million or 1% in engineering and development expenses from 2006 to 2007 was due in part to a $10.3 million increase in spending related to new products and entry into adjacent markets, primarily in the Semiconductor Test segment. This was partially offset by lower variable employee compensation of $8.4 million.

Selling and Administrative

Selling and administrative expenses were as follows:

	2008			2007			2006			2007-2008 Change			2006-2007 Change
	(dollars in millions)
Selling and Administrative	$	247.8		$	248.1		$	278.8		$	(0.3	)	$	(30.7	)
Percent of Total Revenue		22.4	%		22.5	%		20.6	%

The decrease in selling and administrative spending of $0.3 million from 2007 to 2008 consists of the following: $14.7 million decrease due to lower labor costs from reductions in headcount, $7.0 million decrease due to lower variable employee compensation, partially offset by $18.5 million increase due to the acquisition of Nextest and $3.0 million increase related to the acquisition of Eagle Test.

The decrease in selling and administrative spending of $30.7 million or 11% from 2006 to 2007 consists of the following: $13.5 million decrease due to lower variable employee compensation, $17.2 million decrease due to lower transition expenses, including the consolidation of facilities in Massachusetts and costs associated with the outsourcing of certain information technology functions, both of which occurred in 2006.

Acquired Intangible Assets Amortization

Acquired intangible assets amortization expense was as follows:

	2008			2007			2006			2007-2008 Change		2006-2007 Change
	(dollars in millions)
Acquired Intangible Assets Amortization	$	20.6		$	3.7		$	3.6		$	16.9	$	0.1
Percent of Total Revenue		1.9	%		0.3	%		0.3	%

Acquired intangible assets amortization expense increased from 2007 to 2008 due to the acquisitions of Nextest and Eagle Test.

Goodwill Impairment

In 2008, we recorded a non-cash impairment charge of $333.3 million. We experienced a worsening in our demand outlook during the fourth quarter of 2008. This sharp decline is not expected to recover in the near term. Consequently, this has led to an impairment of our goodwill of $333.3 million as of December 31, 2008.

30

In-process Research and Development

In 2008, we recorded an expense of $1.6 million related to in-process research and development related to the acquisition of Nextest and Eagle Test.

On March 7, 2007, we purchased in-process enabling test technology and hired certain engineers from MOSAID Technologies Inc. for $17.6 million, which includes $0.6 million in fees directly related to the acquisition. Of the purchase price, $16.7 million has been allocated to in-process research and development and therefore has been immediately charged to the statement of operations. The balance of the purchase price has been allocated to acquired workforce and fixed assets. In the year ended December 31, 2008, as a result of a workforce reduction, Teradyne recorded an impairment charge of $0.6 million to write-off the acquired workforce asset.

Restructuring and Other, Net

In response to a downturn in the industry, we initiated restructuring activities across all segments to reduce costs and redundancies, principally through headcount reductions and facility consolidations. The tables below represent activities related to these actions. The remaining accrual for severance and benefits is reflected in the accrued employees’ compensation and withholdings account on the balance sheet and is expected to be paid in 2009. The remaining accrual for lease payments on vacated facilities is reflected in the other accrued liabilities account and the long-term other accrued liabilities account and is expected to be paid out over the lease terms, the latest of which expires in 2013. We expect to pay out approximately $2.4 million against the lease accruals over the next twelve months. Our future lease commitments are net of expected sublease income of $7.7 million as of December 31, 2008. We have subleased approximately 64% of our unoccupied space as of December 31, 2008.

Interest and Other, net

	2008			2007			2006			2007-2008 Change			2006-2007 Change
	(in millions)
Interest income	$	12.6		$	39.1		$	44.6		$	(26.5	)	$	(5.5	)
Interest expense and other, net	$	(14.2	)	$	(1.1	)	$	(11.6	)	$	(13.1	)	$	10.5

The interest income decreased by $26.5 million, from $39.1 million in 2007 to $12.6 million in 2008, due primarily to lower cash balances as a result of the acquisition of Nextest and Eagle Test and stock repurchase activity. The interest income decrease of $5.5 million, from $44.6 million in 2006 to $39.1 million in 2007, was primarily attributable to lower cash balances due to the stock repurchase activity in 2007.

The increase in interest expense and other, net of $13.1 million, from $1.1 million in 2007 to $14.2 million in 2008, was due primarily to recognizing other-than-temporary losses related to marketable securities and realized losses from sales of marketable securities. The decrease in interest expense and other, net of $10.5 million, from $11.6 million in 2006 to $1.1 million in 2007, was due primarily to the repayment of our 3.75% Senior Convertible Notes in the fourth quarter of 2006.

(Loss) Income from Continuing Operations before Income Taxes

	2008			2007		2006		2007-2008 Change			2006-2007 Change

Total	$	(386.0	)	$	79.2	$	236.0	$	(465.2	)	$	(156.8	)

The decrease in income from continuing operations before income taxes from 2007 to 2008 is primarily due to the goodwill impairment charge in 2008 and increased restructuring and other costs in 2008 compared to 2007.

33

The decrease in income from continuing operations before income taxes from 2006 to 2007 was mainly due to the 20% reduction in revenue in the Semiconductor Test segment, which was a result of SOC device units growing at a lower rate in 2007 compared to 2006. The increase in Corporate from 2006 to 2007 is primarily related to the elimination of our interest expense due to the repayment of our Notes in 2006 and gains from sales of real estate which totaled $3.6 million.

Income Taxes

The income tax expense from continuing operations for 2008 and 2007 totaled $12.6 million and $7.4 million, respectively. The expense relates primarily to tax provisions for foreign taxes. During 2006, the income tax expense from continuing operations totaled $27.9 million. The expense relates primarily to a tax provision for foreign taxes offset by benefits from a $6.0 million credit related to U.S. pension funding and the settlement of a California income tax audit for 1998 through 2000.

Contractual Obligations

The following table reflects our contractual obligations as of December 31, 2008:

(1) Non-cancelable lease payments have not been reduced by sublease income of $7.7 million due in the future under non-cancelable sublease agreements.

Liquidity and Capital Resources

Our cash, cash equivalents and marketable securities balance decreased $368.6 million in 2008 from 2007, to $374.3 million. Cash activity for 2008, 2007 and 2006 was as follows (in millions):

	2008			2007			2006			2007-2008 Change			2006-2007 Change

34

In 2008, changes in operating assets and liabilities, net of product lines and businesses sold and acquired, provided cash of $38.6 million. This was due primarily to a decrease in accounts receivable of $118.2 million due to a decrease in sales volume in the fourth quarter of 2008 and a decrease in days sales outstanding from 66 days in 2007 to 51 days in 2008, as a result of improved collections. This was partially offset by a decrease in accounts payable and other accruals of $34.4 million and an increase in other assets of $29.9 million.

In 2007, changes in operating assets and liabilities, net of product lines and businesses sold and acquired, used cash of $44.2 million. This was due to a number of factors including, an increase in accounts receivable of $33.7 million due to an increase in days sales outstanding from 55 days in 2006 to 66 days in 2007, a reduction of accrued income taxes of $30.9 million due to the payments of 2006 foreign income taxes around the world, and an increase in other assets of $25.0 million primarily related to balances due for inventory provided to our outsourced subcontract manufacturer of $15.7 million. These uses of cash were partially offset by a decrease in our inventory balances due to shorter cycle times with our FLEX products.

In 2006, changes in operating assets and liabilities, net of product lines and businesses sold and acquired, provided cash of $169.1 million primarily due to a decrease in accounts receivable balances of $67.9 million resulting mostly from the decrease in sales volume in the fourth quarter of 2006 compared to the fourth quarter of 2005. Additionally, there was a decrease in inventory of $79.3 million due to shorter cycle times with our FLEX products, and an increase of $32.8 million in accrued income taxes due to higher foreign income taxes in 2006 compared to 2005. These providers of cash were partially offset by retirement plan contributions of $30.2 million of which $20.0 million was a contribution to our U.S. Qualified Pension Plan.

Investing activities consist of purchases, sales and maturities of marketable securities, cash paid for acquisitions of businesses or technology, proceeds from the sale of land and buildings, proceeds from asset and product line disposals, cash paid for purchases of capital assets. In 2008, we completed the acquisition of Nextest and Eagle Test, for a total cash purchase price and related fees, net of cash acquired, of $574.3 million. In March 2007, we bought an enabling technology from MOSAID Technologies Inc. for a purchase price and related costs totaling $17.6 million. Capital expenditures were $87.2 million in 2008, $86.1 million in 2007 and $110.0 million in 2006. Capital expenditures decreased by $23.9 million in 2007 compared to 2006, primarily due to a decrease of internally manufactured systems for use in marketing and engineering activities in Semiconductor Test of approximately $18.1 million. The remainder of the decrease was attributable to lower purchases of manufacturing and engineering equipment across Teradyne. Proceeds from asset disposals were $61.7 million, $8.8 million and $85.0 million in 2008, 2007 and 2006, respectively and primarily consist of sales of real estate. Investing activities of discontinued operations provided $10.8 million of cash in 2007. Included in this balance is the net proceeds we received related to the sale of our Broadband Test Division to Tollgrade in August 2007.

Financing activities include proceeds from revolving credit facility, issuance of our common stock, repurchases of our common stock as well as repayments of debt.

In November of 2008, we obtained a revolving credit facility that provided net cash of $119.7 million. The credit facility will be available on a revolving basis until November 14, 2011. As of December 31, 2008, the outstanding balance under the credit facility was $122.5 million. We may optionally prepay loans or reduce the credit facility commitments at any time, without penalty. Borrowings under the credit facility are guaranteed by certain domestic subsidiaries of Teradyne, currently Nextest and Eagle Test. The obligations of Teradyne and the guarantors are collateralized by (i) all personal property of Teradyne and each guarantor, (ii) all present and future shares of capital stock of (or other ownership or profit interest in) each of Teradyne’s present and future subsidiaries (limited to 65% of the capital stock of each first-tier foreign subsidiary), and (iii) all real property of Teradyne and each guarantor, if the ratio of consolidated earnings before interest, taxes, depreciation and amortization (EBITDA) to consolidated indebtedness, for any period of four consecutive fiscal quarters, exceeds 2.5 to 1.0. The credit facility contains customary representations and warranties, as well as affirmative and negative covenants, including the financial measures of a leverage ratio, fixed charge coverage ratio and an available domestic cash to total revolving borrowings ratio. As of December 31, 2008, we were in compliance with the financial covenants contained in the credit facility.

35

During 2008, 2007 and 2006, issuances of common stock under stock option and stock purchase plans provided cash of $17.8 million, $23.2 million and $23.3 million, respectively.

In July 2006, our Board of Directors authorized a stock repurchase program which was completed in October 2007. In total, $400 million of common stock was repurchased in the open market or in privately negotiated transactions. During 2006, we repurchased 10.6 million shares of common stock for $137.8 million for an average price per share of $12.98. During 2007, we repurchased 18.3 million shares of common stock for $273.7 million for an average price per share of $14.94. In November 2007, our Board of Directors authorized another stock repurchase program, allowing us to spend an aggregate of $400 million to repurchase shares of our common stock. During 2008, we repurchased 7.5 million shares of common stock for $91.2 million at an average price of $12.20 per share.

In October 2001, we issued $400 million principal amount of the Notes in a private placement and received net proceeds of $389 million. The Notes were convertible at the option of the holders at a rate which was equivalent to a conversion price of approximately $26.00 per share, which was equal to a conversion rate of approximately 38.4615 shares of common stock per $1,000 principal amount of Notes. We made annual interest payments of $15 million, paid semi-annually, on the Notes commencing on April 15, 2002. During 2004 and 2005, we repurchased $100 million of the outstanding Notes pursuant to authorization from our Board of Directors. The decision to repurchase a portion of the Notes was based on the fair market value of the Notes being below the return we would earn on high grade investment securities. On January 26, 2006, management was given further authorization by our Board to repurchase up to the full $300 million of the principal amount that remained outstanding under the Notes through open market purchases, privately negotiated transactions and auctions for a price not to exceed 100% of the principal amount plus any accrued but unpaid interest thereon. During 2006, repayments of long-term debt and notes payable used cash of $304.6 million. In the first and third quarter of 2006, we repurchased Notes of $15.0 million and $24.0 million, respectively, and we repaid the remaining $261 million in the fourth quarter of 2006

We operate in a highly cyclical industry and we may experience, with relatively short notice, significant fluctuations in demand for our products. This could result in a material effect on our liquidity position. We expect, based upon our current estimate of our revenue and operating results for fiscal year 2009, that our cash, cash equivalents and marketable securities balance of $374.3 million will be sufficient to meet our cash requirements for the next twelve months. If our estimates of revenue and operating results for fiscal year 2009 significantly decrease, we could be required to obtain additional financing. However, if financing is necessary, there can be no assurance that such capital will be available or that the terms will be acceptable to us. Inflation has not had a significant long-term impact on earnings

Retirement Plans

We adopted the funded status recognition provision of SFAS 158 effective December 31, 2006. This standard amends SFAS 87, 88, 106, and 132(R). SFAS 158 requires an employer with defined benefit plans or other postretirement benefit plans to recognize an asset or a liability on its balance sheet for the overfunded or underfunded status of the plans as defined by SFAS 158. The pension asset or liability represents the difference between the fair value of the pension plan’s assets and the projected benefit obligation as of December 31. For other postretirement benefit plans, the liability is the difference between the fair value of the plan’s assets and the accumulated postretirement benefit obligation as of December 31.

Our pension expense, which includes the U.S. Qualified Pension Plan, certain Qualified Plans for non-U.S. subsidiaries and a Supplemental Executive Defined Benefit Plan, was approximately $3.4 million for the year ended December 31, 2008. The largest portion of our 2008 pension expense was $2.8 million for our Supplemental Executive Defined Benefit Plan. Pension expense is calculated based upon a number of actuarial assumptions, a significant input to the actuarial models that measure pension benefit obligations. Two assumptions: discount rate and expected return on assets are important elements of pension plan expense and

36

asset/liability measurement. We evaluate these critical assumptions at least annually on a plan and country specific basis. We evaluate other assumptions involving demographic factors, such as retirement age, mortality and turnover periodically, and update them to reflect our experience and expectations for the future.

In developing the expected return on plan assets assumption, we evaluated input from our investment manager and pension consultants, including their review of asset class return expectations. Based on this review, we believe that 7.75% was an appropriate rate to use for fiscal year 2008. We will continue to evaluate the expected return on plan assets at least annually, and will adjust the rate as necessary. The current asset allocation for our U.S. Qualified Pension Plan is 37% invested in equity securities and 63% invested in fixed income securities. Our investment manager regularly reviews the actual asset allocation and periodically rebalances the portfolio to ensure alignment with our targeted allocations.

We base our determination of pension expense or benefit on a market-related valuation of assets, which reduces year-to-year volatility. This market-related valuation recognizes investment gains or losses over a five-year period from the year in which they occur. Investment gains or losses for this purpose are the difference between the expected return calculated using the market-related value of assets and the actual return on assets. Since the market-related value of assets recognizes gains or losses over a five-year period, the future value of assets will be impacted as previously deferred gains or losses are recognized. As of December 31, 2008, under the U.S. Qualified Pension Plan, we had cumulative losses of approximately $62.5 million, which remain to be recognized in the calculation of the market-related value of assets. The discount rate that we utilized for determining future pension obligations for the U.S. Qualified Pension Plan is based on Citigroup Pension Index adjusted for the plan’s expected cash flows and was 6.2% at December 31, 2008, down from 6.5% at December 31, 2007. We estimate that in 2009 we will recognize approximately $1.1 million of pension expense for the U.S. Qualified Pension Plan. The pension expense estimate for 2009 is based on a 6.2% discount rate, and 7.75% return on Plan assets. Future pension expense or benefit will depend on future investment performance, changes in future discount rates and various other factors related to the employee population participating in our pension plans. As of December 31, 2008, we had unrecognized pension losses of $144.6 million, of which $127.3 million is for the U.S. Qualified Pension Plan.

We performed a sensitivity analysis, which expresses the estimated U.S. Qualified Pension Plan pension expense (benefit) that would have resulted for the year ended December 31, 2008, if we changed either the discount rate or the expected return on plan assets.

	Discount Rate
Return on Plan Assets	5.7%		6.2%			6.7%
	(in millions)
7.25%	$	3.8	$	2.3		$	1.2
7.75%		2.5		1.1			0.0
8.25%		1.3		(0.1	)		(1.2	)

The assets of the U.S. Qualified Pension Plan consist primarily of equity and fixed income securities. The value of our U.S. Qualified Pension Plan assets has decreased from $254.0 million at December 31, 2007 to $184.5 million at December 31, 2008. Our funding policy is to make contributions to the Pension Plan in accordance with local laws and to the extent that such contributions are tax deductible. During 2008, there were no additional contributions made to the U.S. Qualified Pension Plan, and we made $4.3 million of additional contributions to certain Qualified Plans for non-U.S. subsidiaries. Based upon the U.S. Qualified Pension Plan funded status as of December 31, 2008, we do not expect to make any contributions to this plan in 2009. Contributions that will be made in 2009 to certain Qualified Plans for non-U.S. subsidiaries are based on local statutory requirements and will be approximately $3.1 million.

Equity Compensation Plans

In addition to our 1996 Employee Stock Purchase Plan discussed in “Note O: Stock Based Compensation” in Notes to Consolidated Financial Statements, we have the 2006 Equity and Cash Compensation Incentive Plan (the “2006 Equity Plan”) under which equity securities are authorized for issuance. The 2006 Equity Plan was approved by stockholders on May 25, 2006. The 2006 Equity Plan replaces our 1996 Non-Employee Director Stock Option Plan, our 1997 Employee Stock Option Plan, and our 1991 Employee Stock Option Plan, each of which were terminated upon the shareholders approval of the 2006 Equity Plan. We may not issue any additional option grants or awards under the terminated plans, but the options and awards previously granted and currently outstanding under these plans will remain in effect until the earlier of the date of their exercise, vesting or expiration, as applicable.

The following table presents information about these plans as of December 31, 2008 (share numbers in thousands):

Plan category	Number of securities to be issued upon exercise of outstanding options, warrants and rights		Weighted-average exercise price of outstanding options, warrants and rights		Number of securities remaining available for future issuance under equity compensation plans (excluding securities reflected in column (1))

(1) Includes 4,642,185 shares of restricted stock units that are not included in the calculation of the weighted average exercise price.

(2) Includes 504,519 shares of restricted stock units that are not included in the calculation of the weighted average exercise price.

(3) Consists of 6,875,000 securities available for issuance under the 2006 Equity Plan and 4,197,000 of securities available for issuance under the Employee Stock Purchase Plan.

(4) In connection with the acquisition of GenRad, Inc. in October 2001 (the “Acquisition”), we assumed the outstanding options granted under the GenRad, Inc. 1991 Equity Incentive Plan, the GenRad, Inc. 1991 Directors’ Stock Option Plan and the GenRad, Inc. 1997 Non-Qualified Employee Stock Option Plan (collectively, the “GenRad Plans”). Upon the consummation of the Acquisition, these options became exercisable for shares of our common stock based on an exchange ratio of 0.1733 shares of our common stock for each share of GenRad’s common stock. No additional options will be granted pursuant to the GenRad Plans. As of December 31, 2008, there were outstanding options exercisable for an aggregate of 88,849 shares of our common stock pursuant to the GenRad Plans, with a weighted average exercise price of $54.58 per share.

(5) In connection with the acquisition of Nextest Systems Corporation (the “Nextest Acquisition”), we assumed the options and restricted stock units granted under the Nextest Systems Corporation 1998 Equity Incentive Plan, as amended, and the Nextest Systems Corporation 2006 Equity Incentive Plan (collectively, the “Nextest Plans”). Upon the consummation of the Nextest Acquisition, these options and restricted stock units were converted automatically into, respectively, options to purchase and restricted stock units representing, an aggregate of 4,417,594 shares of our common stock. No additional awards will be granted under the Nextest Plans. As of December 31, 2008, there were outstanding options exercisable for an aggregate of 2,127,936 shares of our common stock pursuant to the Nextest Plans, with a weighted average exercise price of $3.17 per share. As of December 31, 2008, there were outstanding restricted stock units covering an aggregate of 479,772 shares of our common stock, none of which are included in the calculation of the weighted average exercise price.

(6) In connection with the acquisition of Eagle Test Systems, Inc. (the “Eagle Acquisition”), we assumed the options granted under the Eagle Test Systems, Inc. 2003 Stock Option and Grant Plan and the Eagle Test Systems, Inc. 2006 Stock Option and Incentive Plan (collectively, the “Eagle Plans”). Upon the consummation of the Eagle Acquisition, these options were converted automatically into options to purchase an aggregate of 3,594,916 shares of our common stock. No additional awards will be granted under the Eagle Plans. As of December 31, 2008, there were outstanding options exercisable for an aggregate of 3,130,129 shares of our common stock pursuant to the Eagle Plans, with a weighted average exercise price of $3.71 per share.

The purpose of the 2006 Equity Plan is to motivate employees, officers, directors, consultants and advisors by providing equity ownership and compensation opportunities in Teradyne. The aggregate number of shares available under the 2006 Equity Plan as of December 31, 2008 was 6,875,000 shares of our common stock. The 2006 Equity Plan authorizes the grant of stock-based awards in the form of (1) non-qualified and incentive stock options, (2) stock appreciation rights, (3) restricted stock awards and restricted stock unit awards, (4) phantom stock, and (5) other stock-based awards. Awards may be tied to time-based vesting schedules and/or performance-based vesting measured by reference to performance criteria chosen by the Compensation Committee of the Board of Directors, which administers the 2006 Equity Plan. Awards may be made to any employee, officer, consultant and advisor of Teradyne and our subsidiaries, as well as, to our directors. The maximum number of shares of stock-based awards that may be granted to one participant during any one fiscal year is 2,000,000 shares of common stock. The 2006 Equity Plan will expire on May 24, 2016. In 2008 and 2007, we only issued restricted stock unit awards to our employees and directors.

As of December 31, 2008 total unrecognized compensation expense related to non-vested awards and options totaled $40.3 million, and is expected to be recognized over a weighted average period of 2.65 years.

Related Party Transaction

During 2007, Paul Tufano, a member of our Board of Directors, was Executive Vice President, Chief Financial Officer and Interim Chief Executive Officer of Solectron Corporation until it was acquired by Flextronics in October 2007. Mr. Tufano ceased being an employee of Solectron or Flextronics in October 2007. In the ordinary course of business, Teradyne has for the last ten years purchased printed circuit board assemblies from Solectron, and has also sold in-circuit testers to Solectron which Teradyne refers to as Flextronics. In August 2007, prior to the Flextronics acquisition, we expanded our contract with Solectron to have it provide additional manufacturing and test services, including areas of final configuration and test for most of Teradyne’s FLEX family of products. In the years ended December 31, 2007 and 2006, we purchased $207.8 million and $229.9 million, respectively, of printed circuit board assemblies and services from Flextronics. Sales of in-circuit testers to Flextronics for the years ended December 31, 2007 and 2006 were $4.0 million and $5.7 million, respectively. As of December 31, 2007, $19.8 million was included in accounts payable and $17.5 million was included in accounts receivable, representing amounts due to/from Flextronics.

Recently Issued Accounting Pronouncements

In December 2007, the FASB issued Statement of Financial Accounting Standards No. 141(R), “Business Combinations.” (“SFAS No. 141(R)”) This Statement replaces FASB Statement No. 141, “Business Combinations.” SFAS No. 141(R) establishes new principles and requirements for how an acquiring company 1) recognizes and measures in its financial statements the identifiable assets acquired, the liabilities assumed, and any non-controlling interest in the acquiree, 2) recognizes and measures the goodwill acquired in the business combination or a gain from a bargain purchase, and 3) determines what information to disclose to enable users of the financial statements to evaluate the nature and financial effects of the business combination. SFAS No. 141(R) is effective for business combinations occurring in the fiscal year beginning on or after December 15, 2008. The adoption of SFAS No. 141(R) is not expected to materially impact our consolidated financial position, results of operations or liquidity. Subsequent to the adoption of SFAS No. 141(R), the resolution of existing balances related to uncertain tax positions from prior acquisitions that differ from previously recorded amounts will be adjusted through earnings.

In February 2008, the FASB issued FSP FAS No. 157-2, “Effective Date of FASB Statement No. 157”. The FSP defers the provisions of SFAS No. 157 with respect to nonfinancial assets and nonfinancial liabilities that are measured at fair value on a nonrecurring basis subsequent to initial recognition until fiscal years beginning after November 15, 2008. Items in this classification include goodwill, intangible assets with indefinite lives, guarantees and certain other items. The adoption of FSP FAS 157-2 effective January 1, 2009 will not have a material impact on our financial position or results of operations.

In March 2008, the FASB issued Statement of Financial Accounting Standards No. 161, “Disclosures about Derivative Instruments and Hedging Activities” (“SFAS No. 161”), an amendment of FASB Statement No. 133. “Accounting for Derivative Instruments and Hedging Activities”. SFAS No. 161 expands the current disclosure requirements of SFAS No. 133, “Accounting for Derivative Instruments and Hedging Activities,” such that entities must now provide enhanced disclosures on a quarterly basis regarding how and why the entity uses derivatives; how derivatives and related hedged items are accounted for under SFAS No. 133 and how derivatives and related hedged items affect the entity’s financial position, performance and cash flow. SFAS No. 161 is effective prospectively for periods beginning on or after November 15, 2008. We will adopt SFAS No. 161 in fiscal year 2009. The adoption of SFAS No. 161 will not have an impact on our financial position or results of operations.

In April 2008 the FASB issued Staff Position No. 142-3 (“FSP No. 142-3”), “Determination of the Useful Life of Intangible Assets”. This FSP amends the guidance in FASB Statement No. 142 ,”Goodwill and Other Intangible Assets”, about estimating useful lives of recognized intangible assets and requires additional disclosures related to renewing or extending the terms of recognized intangible assets. In estimating the useful life of a recognized intangible asset, the FSP requires companies to consider their historical experience in renewing or extending similar arrangements together with the asset’s intended use, regardless of whether the

40

arrangements have explicit renewal or extension provisions. The FSP is effective for fiscal years beginning after December 15, 2008 and is to be applied prospectively to intangible assets acquired after the effective date. The disclosure requirements are to be applied prospectively to all intangible assets. The adoption of FSP No. 142-3 will not have an impact on our financial position or results of operations.

Item 7A: Quantitative and Qualitative Disclosures About Market Risks

Concentration of Credit Risk

Financial instruments which potentially subject us to concentrations of credit risk consist principally of cash equivalents, marketable securities, forward currency contracts and accounts receivable. Our cash equivalents consist primarily of money market funds invested in U.S. Treasuries and government agencies. All of our auction rate marketable securities are AAA, AA or A rated by one or more of the major credit rating agencies and are substantially guaranteed by a U.S. Department of Education agency or a third party insurer. We place 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. We perform ongoing credit evaluations of its customers’ financial condition and from time to time may require customers to provide a letter of credit from a bank to secure accounts receivable.

Exchange Rate Risk Management

We regularly enter into foreign currency forward contracts to hedge the value of our net monetary assets in the European Euro, Great Britain Pound, Japanese Yen and the Taiwan Dollar. These foreign currency forward contracts have maturities of less than one year. These contracts are used to reduce our risk associated with exchange rate movements, as gains and losses on these contracts are intended to offset exchange losses and gains on underlying exposures. In addition, we periodically hedge anticipated cash flow transactions with foreign currency forward contracts. The gains and losses on these contracts are deferred and recognized in the same period as the hedged transaction is recognized in income. We do not engage in currency speculation.

We performed a sensitivity analysis assuming a hypothetical 10% fluctuation in foreign exchange rates to the hedging contracts and the underlying exposures described above. As of December 31, 2008, 2007, and 2006, the analysis indicated that these hypothetical market movements would not have a material effect on our consolidated financial position, results of operations or cash flows.

Interest Rate Risk Management

We are exposed to potential loss due to changes in interest rates. Our interest rate exposure is primarily in the United States in short-term and long-term marketable securities.

In order to estimate the potential loss due to interest rate risk, a 10% fluctuation in interest rates was assumed. Market risk for the short and long-term marketable securities was estimated as the potential change in the fair value resulting from a hypothetical change in interest rates for securities contained in the investment portfolio. On these bases, the potential change in fair value from changes in interest rates is $0.6 million and $0.3 million as of December 31, 2008 and 2007, respectively.

Item 8: Financial Statements and Supplementary Data

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Shareholders of Teradyne, Inc. (the “Company”):

In our opinion, the accompanying consolidated financial statements listed in the listed in the index appearing under Item 15(a)(1) present fairly, in all material respects, the financial position of Teradyne, Inc. and its subsidiaries at December 31, 2008 and 2007, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2008 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 15 (a)(2) presents fairly, in all material respects, the information set forth therein when read in conjunction with the related consolidated financial statements. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2008, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company’s management is responsible for these financial statements and financial statement schedule, for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in Management’s Annual Report on Internal Control over Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on these financial statements, on the financial statement schedule, and on the Company’s internal control over financial reporting based on our integrated audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the financial statements included 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. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

As discussed in Note R of the consolidated financial statements, the Company changed the manner in which it accounts for uncertain tax positions in 2007. As discussed in Notes B and N to the consolidated financial statements, the Company changed the manner in which it accounts for share-based compensation in 2006 and the manner in which it accounts for defined benefit pension and other postretirement plans effective December 31, 2006.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

As described in Item 9A of the consolidated financial statements, management has excluded Nextest Systems Corporation and Eagle Test Systems from its assessment of internal control over financial reporting as of December 31, 2008 because they were acquired by the Company in purchase business combinations during 2008. Nextest Systems Corporation and Eagle Test Systems are wholly-owned subsidiaries whose total assets represent 4% and 6%, respectively, and total revenues represent 7% and 1%, respectively, of the related consolidated financial statement amounts as of and for the year ended December 31, 2008.

TERADYNE, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

A. THE COMPANY

Teradyne, Inc. is a leading global supplier of automatic test equipment.

Teradyne’s automatic test equipment products and services include:

• semiconductor test (“Semiconductor Test”) systems;

• military/aerospace test (“Mil/Aero”) instrumentation and systems, circuit-board test and inspection (“Commercial Board Test”) systems and automotive diagnostic and test (“Diagnostic Solutions”) systems, collectively these products represent “Systems Test Group”.

B. ACCOUNTING POLICIES

Basis of Presentation

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

In August 2007, Teradyne sold Broadband Test Division, its Digital Subscriber Line and telephone network test division. The results of operations of Broadband Test Division as well as balance sheet amounts pertaining to this businesses has been classified as discontinued operations in the consolidated financial statements (see “Note E: Discontinued Operations”).

Preparation of Financial Statements and Use of Estimates

The preparation of consolidated financial statements requires management 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, management evaluates its estimates, including those related to inventories, investments, goodwill, intangible and other long-lived assets, doubtful accounts, income taxes, pensions, warranties, and loss contingencies. Management 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 significantly from these estimates.

Revenue Recognition

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. Title and risk of loss generally pass to Teradyne’s customers upon shipment or at delivery destination point. In circumstances where either title or risk of loss pass upon destination, acceptance or cash payment, Teradyne defers revenue recognition until such events occur.

Teradyne’s equipment includes embedded software which is considered incidental to the product. Revenue is recognized upon shipment or at delivery destination point, provided that customer acceptance criteria can be demonstrated prior to shipment. Certain contracts require Teradyne to perform tests of the product to ensure that performance meets the published product specifications or customer requested specifications, which are generally conducted prior to shipment. Where the criteria cannot be demonstrated prior to shipment, revenue is deferred until customer acceptance has been received.

B. ACCOUNTING POLICIES—(Continued)

For multiple element arrangements Teradyne defers the fair value of any undelivered elements of the contract. Teradyne also defers the portion of the sales price that is not due until acceptance, which represents deferred profit. For a delivered item to be considered a separate unit, the delivered item must have value to the customer on a standalone basis, there must be objective and reliable evidence of fair value of the undelivered items in the arrangement and the delivery or performance of the undelivered item must be considered probable and substantially in the control of Teradyne. 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. Teradyne’s post-shipment obligations include installation, training services, one-year standard warranties, and extended warranties. Installation does not alter the product capabilities, does not require specialized skills or tools and can be performed by the customers or other vendors. Installation is typically provided within five to fifteen days of product shipment and is completed within one to two days thereafter. Training services are optional and do not affect the customer’s ability to use the product. Teradyne defers revenue for the fair value of installation and training. Extended warranties constitute warranty obligations beyond one year and Teradyne defers revenue in accordance with FASB Technical Bulletin 90-1, “Accounting for Separately Priced Extended Warranty and Product Maintenance Contracts”.

Teradyne’s products are generally subject to warranty and related costs of the warranty are provided for in cost of revenue when product revenue is recognized. Teradyne classifies shipping and handling costs in cost of revenue. Service revenue is recognized over the contractual period or as the services are performed.

Teradyne generally does not provide its customers with contractual rights of return for any of its products.

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, “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. In instances where an arrangement contains multiple elements, revenue is deferred related to the undelivered elements to the extent that vendor-specific objective evidence of fair value (“VSOE”) exists for such elements. In instances where VSOE does not exist for one or more of the undelivered elements of an arrangement, all revenue related to the arrangement is deferred until all elements have been delivered. VSOE 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 the percentage of incurred costs to estimated total costs. These arrangements require 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 they are determined. With respect to contract change orders, claims or similar items, judgment must be used in estimating related amounts and assessing the potential for realization. Such amounts are only included in the contract value when they can be reliably estimated and realization is reasonably assured, generally upon receipt of a customer approved change order. As of December 31, 2008 and 2007, Teradyne had $4.5 million and $10.5 million in unbilled amounts on long-term contracts included in accounts receivable, respectively. These amounts will be billed on a milestone basis in accordance with contractual terms.

B. ACCOUNTING POLICIES—(Continued)

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 inventories for net realizable value. Teradyne records a provision for both excess and obsolete inventory when such write-downs or write-offs are identified through the quarterly review process. The inventory valuation is based upon assumptions about future demand, product mix and possible alternative uses.

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
Building improvements	5 to 10 years
Leasehold improvements	Lesser of lease term or useful life
Furniture and fixtures	10 years
Test systems manufactured internally	6 years
Machinery and equipment	3 to 5 years
Software	3 to 5 years

Test systems manufactured internally are used by Teradyne for customer evaluations and manufacturing and support of its customers. Teradyne depreciates the test systems manufactured internally over a six-year life to cost of revenues and selling and administrative expenses. Teradyne often sells internally manufactured test equipment to customers. Upon the sale of an internally manufactured test system, the net book value of the system is transferred to inventory and expensed as cost of revenues. The net book value of internally manufactured test systems sold in the years ended December 31, 2008, 2007 and 2006 was $41.4 million, $33.0 million and $40.0 million, respectively.

Investments

Teradyne accounts for its investments in debt and equity securities in accordance with the provisions of Statement of Financial Accounting Standards No 115 “Accounting for Certain Investments in Debt and Equity Securities” (“SFAS No. 115”) and FASB Staff Positions Nos. FAS 115-1 and FAS 124-1 “The Meaning of Other-Than-Temporary Impairment and Its Application to Certain Investments”. SFAS No. 115 requires that certain debt and equity securities be classified into one of three categories; trading, available-for-sale or held-to-maturity securities. On a quarterly basis Teradyne reviews its investments to identify and evaluate those that have an indication of a potential other-than-temporary impairment. Factors considered in determining whether a loss is other-than-temporary include:

• The length of time and the extent to which the market value has been less than cost;

49

TERADYNE, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

B. ACCOUNTING POLICIES—(Continued)

• The financial condition and near-term prospects of the issuer; and

• The intent and ability to retain the investment in the issuer for a period of time sufficient to allow for any anticipated recovery in market value.

Effective January 1, 2008, Teradyne adopted Statement of Financial Accounting Standards No. 157, “Fair Value Measurements” (“SFAS No. 157”) for financial assets and liabilities. As defined in SFAS No. 157, fair value is the price that would be received from the sale of an asset or paid to transfer a liability in an orderly transaction between market participants. Teradyne uses the market and income approach techniques to value its financial instruments and there were no changes in valuation techniques during the year ended December 31, 2008. SFAS No. 157 requires that assets and liabilities carried at fair value be classified and disclosed in one of the following three categories:

Level 1: Quoted prices in active markets for identical assets as of the reporting date.

Level 2: Inputs other than Level 1, that are observable either directly or indirectly as of the reporting date. For example, a common approach for valuing fixed income securities is the use of matrix pricing. Matrix pricing is a mathematical technique used to value securities by relying on the securities’ relationship to other benchmark quoted prices, and therefore is considered a Level 2 input.

Level 3: Unobservable inputs that are not supported by market data. Unobservable inputs are developed based on the best information available, which might include Teradyne’s own data.

In accordance with SFAS No. 157, Teradyne measures its investments in debt and equity investments at fair value. Teradyne’s marketable securities are classified within Level 1 and Level 2 with the exception of Teradyne’s investments in auction rate securities, which are classified within Level 3. Teradyne’s investments in auction rate securities are classified within Level 3 because there are no active markets for the auction rate securities and therefore Teradyne is unable to obtain independent valuations from market sources. The valuation technique used under Level 3 consists of a discounted cash flow analysis which includes numerous factors, such as type of security, tax status, credit quality, duration, insurance and the portfolio composition as well as observable market data including yield or spreads of trading instruments.

Goodwill, Intangible and Long-Lived Assets

Teradyne accounts for its goodwill and intangible assets in accordance with Statement of Financial Accounting Standards (“SFAS”) No. 142, “Goodwill and Other Intangible Assets.” Intangible assets are amortized over their estimated useful economic life and are carried at cost less accumulated amortization. Goodwill is assessed for impairment at least annually in the fourth quarter, on a reporting unit basis, or more frequently when events and circumstances occur indicating that the recorded goodwill may be impaired. If the book value of a reporting unit exceeds its fair value, the implied fair value of goodwill is compared with the carrying amount of goodwill. If the carrying amount of goodwill exceeds the implied fair value, an impairment loss is recorded in an amount equal to that excess.

In accordance with SFAS No. 144 “Accounting for the Impairment or Disposal of Long-Lived Assets,” (“SFAS No. 144”) 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 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 and consist primarily of salaries, contractor fees, building costs, depreciation, and tooling costs.

Advertising Costs

Teradyne expenses all advertising costs as incurred. Advertising costs were $1.5 million, $2.4 million and $2.7 million in 2008, 2007 and 2006, respectively.

Product Warranty

Teradyne generally provides a one-year warranty on its products, commencing upon installation or shipment. A provision is recorded upon revenue recognition to cost of revenues for estimated warranty expense based upon historical experience. Related costs are charged to the warranty accrual as incurred. The balance below is included in other accrued liabilities.

Stock Compensation Plans and Employee Stock Purchase Plan

Equity Plans and Employee Stock Purchase Plan

Under its stock compensation plans, Teradyne has granted stock options and restricted stock units, and employees are eligible to purchase Teradyne’s common stock through its Employee Stock Purchase Plan (“ESPP”).

Stock options to purchase Teradyne’s common stock at 100% of the fair market value on the grant date generally vest in equal installments over four years from the grant date and have a maximum term of seven years. Options granted to non-employee directors are immediately vested, fully exercisable and have a maximum term of either five or seven years.

Restricted stock unit awards granted to employees (excluding executive officers) vest in equal annual installments over four years. Restricted stock unit awards granted to non-employee directors vest after a one year period, with 100% of the award vesting on the first anniversary of the grant date. Restricted stock unit awards granted to executive officers, including the CEO, in January 2006, vest over two years. Restricted stock unit awards granted to executive officers, including the CEO, in January 2008 and 2007 vest over four years. A portion of these restricted stock unit awards granted to executive officers, including the CEO, is subject to time-based vesting and a portion of the awards is subject to performance-based vesting. The percentage level of performance satisfied for performance-based grants is assessed on or near the anniversary of the grant date and, in turn, that percentage level determines the number of performance-based restricted stock units available for vesting over the vesting period; portions of the performance-based grants not available for vesting will be forfeited. Restricted stock units do not have common stock voting rights, and the shares underlying the restricted stock units are not considered issued and outstanding until they become vested. Teradyne expenses the cost of the restricted stock unit awards, which is determined to be the fair market value of the shares at the date of grant, ratably over the period during which the restrictions lapse.

Under the ESPP, eligible employees (including executive officers) may purchase shares of common stock through regular payroll deductions of up to 10% of their eligible compensation. The price paid for the common

B. ACCOUNTING POLICIES—(Continued)

stock is equal to 85% of the lower of the fair market value of Teradyne’s common stock on the first business day and the last business day of the purchase period. There are two six-month purchase periods in each fiscal year.

Effective January 1, 2006, Teradyne adopted the fair value recognition provision of Financial Accounting Standards No. 123 (revised 2004) “Share Based Payment” (“SFAS 123R”), using the modified prospective transition method and therefore has not restated results for prior periods. Under this transition method, stock based compensation expense for the years ended December 31, 2008, 2007 and 2006 includes compensation expense for all stock-based compensation awards granted prior to, but not yet vested as of January 1, 2006, and is calculated based on the grant date fair value estimated in accordance with the original provisions of SFAS No. 123 “Accounting for Stock Based Compensation” (“SFAS 123”). Stock-based compensation expense for all stock-based compensation awards granted after January 1, 2006 is based on the grant-date fair value estimated in accordance with SFAS 123R. As required by SFAS 123R, Teradyne has made an estimate of expected forfeitures and is recognizing compensation costs only for those stock-based compensation awards expected to vest.

Prior to the adoption of SFAS 123R, Teradyne accounted for its equity incentive plans and employee stock purchase plans under the recognition and measurement principles of Accounting Principles Board Opinion No. 25, “Accounting for Stock Issued to Employees” and related Interpretations (“APB 25”). In March 2005, the SEC issued Staff Accounting Bulletin No. 107 (“SAB 107”) regarding the SEC’s interpretation of SFAS 123R and the valuation of share-based payments for public companies. Teradyne has applied provisions of SAB 107 in its adoption of SFAS 123R. The cumulative effect of the initial adoption of SFAS 123R was not material.

On May 26, 2005, the Board of Directors approved the accelerated vesting of certain outstanding, unvested “out of the money” stock options awarded to employees, officers and other eligible participants under Teradyne’s various stock option plans. The stock options that were accelerated had exercise prices that were in excess of $13.26, the closing price of Teradyne’s common stock on the New York Stock Exchange on May 26, 2005 and ranged in exercise price from $13.73 to $41.37 per share. As a result of the vesting acceleration, options to purchase approximately 7.6 million shares became exercisable immediately and Teradyne reduced the compensation expense it otherwise would have been required to record under SFAS 123R by approximately $48.6 million on a pre-tax basis over fiscal years 2006, 2007 and 2008.

The weighted-average fair value of employee stock purchase rights granted pursuant to the ESPP in the first and last six months of 2008 was $2.38 and $1.27, respectively, the first and last six months of 2007 was $3.56 and $2.67, respectively, and the first and last six months of 2006 was $3.81 and $3.48. The fair value of the employees’ purchase rights was estimated using the Black-Scholes option-pricing model with the following assumptions:

	2008		2007		2006
Expected life (years)	0.5		0.5		0.5
Interest rate	2.8	%	5.1	%	4.9	%

As of December 31, 2008, there were 4.2 million shares available for grant under the ESPP.

Income Taxes

Deferred tax assets and liabilities 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. income taxes are not provided for on the earnings of non-U.S. subsidiaries, which are expected to be reinvested indefinitely in operations outside the U.S. For intra-period tax allocations, Teradyne considers only the direct effects of stock options and elects to first utilize non-equity related tax attributes, such as net operating losses and credit carryforwards and then equity-related tax attributes.

Translation of Non-U.S. Currencies

The functional currency for all non-U.S. subsidiaries is the U.S. dollar, except for the Systems Test Group business unit Diagnostic Solutions for which the local currency is its functional currency. All foreign currency denominated monetary assets and liabilities are re-measured on a monthly basis into the functional currency using exchange rates in effect at the end of the period. All foreign currency denominated non-monetary assets and liabilities are re-measured into the functional currency using historical exchange rates. Net foreign exchange gains and losses resulting from re-measurement are included in interest expense and other, net and were immaterial for the years ended December 31, 2008, 2007 and 2006. For Diagnostic Solutions, assets and liabilities are translated into U.S. dollars using exchange rates in effect at the end of the period. Revenue and expense amounts are translated using an average of exchange rates in effect during the period. Translation adjustments are recorded within accumulated other comprehensive loss.

Net (Loss) Income per Common Share

Basic net (loss) income per common share is calculated by dividing net (loss) income by the weighted average number of common shares outstanding during the period. Except where the result would be antidilutive to income before continuing operations, diluted net (loss) income per common share is calculated by dividing net (loss) income by the sum of the weighted average number of common shares plus common stock equivalents, if applicable.

Accounts Receivable and Allowance for Doubtful Accounts

Trade accounts receivable are recorded at the invoiced amount and do not bear interest. 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. Estimated allowances for doubtful accounts are reviewed periodically taking into account the customer’s recent payment history, the customer’s current financial statements and other information regarding the customer’s credit worthiness. Account balances are charged off against the allowance when it is determined the receivable will not be recovered.

Comprehensive Income (Loss)

Comprehensive income (loss) includes net income (loss), unrealized pension gains and losses, unrealized gains and losses on certain investments in debt, equity and derivative securities and cumulative translation adjustments.

C. RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

In December 2007, the FASB issued Statement of Financial Accounting Standards No. 141(R), “Business Combinations.” (“SFAS No. 141(R)”) This Statement replaces FASB Statement No. 141, “Business Combinations” SFAS No. 141(R) establishes new principles and requirements for how an acquiring company 1) recognizes and measures in its financial statements the identifiable assets acquired, the liabilities assumed, and any non-controlling interest in the acquiree, 2) recognizes and measures the goodwill acquired in the business combination or a gain from a bargain purchase, and 3) determines what information to disclose to enable users of the financial statements to evaluate the nature and financial effects of the business combination. SFAS No. 141(R) is effective for business combinations occurring in the fiscal year beginning on or after December 15, 2008. The adoption of SFAS No. 141(R) is not expected to materially impact Teradyne’s consolidated financial position, results of operations or liquidity. Subsequent to the adoption of SFAS No. 141(R), the resolution of existing balances related to uncertain tax positions from prior acquisitions that differ from previously recorded amounts will be adjusted through earnings.

In February 2008, the FASB issued FSP FAS No. 157-2, “Effective Date of FASB Statement No. 157”. The FSP defers the provisions of SFAS No. 157 with respect to nonfinancial assets and nonfinancial liabilities that are measured at fair value on a nonrecurring basis subsequent to initial recognition until fiscal years beginning after November 15, 2008. Items in this classification include goodwill, intangible assets with indefinite lives, guarantees and certain other items. The adoption of FSP FAS 157-2 effective January 1, 2009 will not have a material impact on Teradyne’s financial position or results of operations.

In March 2008, the FASB issued Statement of Financial Accounting Standards No. 161, “Disclosures about Derivative Instruments and Hedging Activities” (“SFAS No. 161”), an amendment of FASB Statement No. 133. “Accounting for Derivative Instruments and Hedging Activities”. SFAS No. 161 expands the current disclosure requirements of SFAS No. 133, “Accounting for Derivative Instruments and Hedging Activities,” such that entities must now provide enhanced disclosures on a quarterly basis regarding how and why the entity uses derivatives; how derivatives and related hedged items are accounted for under SFAS No. 133 and how derivatives and related hedged items affect the entity’s financial position, performance and cash flow. SFAS No. 161 is effective prospectively for periods beginning on or after November 15, 2008. Teradyne will adopt SFAS No. 161 in fiscal year 2009. The adoption of SFAS No. 161 will not have an impact on Teradyne’s financial position or results of operations.

C. RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS—(Continued)

In April 2008 the FASB issued Staff Position No. 142-3 (“FSP No. 142-3”), “Determination of the Useful Life of Intangible Assets”. This FSP amends the guidance in FASB Statement No. 142 , “Goodwill and Other Intangible Assets”, about estimating useful lives of recognized intangible assets and requires additional disclosures related to renewing or extending the terms of recognized intangible assets. In estimating the useful life of a recognized intangible asset, the FSP requires companies to consider their historical experience in renewing or extending similar arrangements together with the asset’s intended use, regardless of whether the arrangements have explicit renewal or extension provisions. The FSP is effective for fiscal years beginning after December 15, 2008 and is to be applied prospectively to intangible assets acquired after the effective date. The disclosure requirements are to be applied prospectively to all intangible assets. The adoption of FSP No. 142-3 will not have an impact on Teradyne’s financial position or results of operations.

E. DISCONTINUED OPERATIONS

On August 1, 2007 Teradyne completed the sale of the Broadband Test Division to Tollgrade Communications, Inc. for $11.3 million in cash. Broadband Test Division had revenues for the seven month period ended July 31, 2007 of $11.2 million and for the year ended December 31, 2006 of $20.6 million. Loss from discontinued operations of the Broadband Test Division for the year ended December 31, 2007 and December 31, 2006 was $6.3 million and $5.6 million, respectively. In 2007, Teradyne recorded a gain on the sale of Broadband Test Division of $5.9 million, net of a tax provision of $0.4 million.

On November 30, 2005 Teradyne completed the sale of its Connection Systems segment to Amphenol Corporation. Loss from discontinued operations of Connection Systems segment for the year ended December 31, 2006 was $3.9 million, relating to a change in estimate to tax expenses from the sale. Under applicable accounting guidance, there is an offsetting tax benefit recorded in continuing operations for the same amount. This tax provision results from the finalization of the 2005 U.S. tax return.

F. ACQUISITIONS

Business

Nextest Systems Corporation

On January 24, 2008, Teradyne completed its acquisition of Nextest Systems Corporation (“Nextest”) of San Jose, California for a total purchase price of $399.8 million, which consisted of $367.8 million of cash paid to acquire the outstanding common stock of Nextest, at a price of $20.00 per share, $25.9 million in fair value of assumed vested stock options and restricted stock units, which were converted into stock options and restricted stock units to purchase Teradyne’s common stock, and $6.1 million of acquisition related transaction costs, which primarily consisted of fees incurred for financial advisory and legal services. The fair value of stock options was estimated using the following weighted average assumptions:

Expected life	3.6 years
Expected volatility	40.6%
Risk-free interest rate	2.8%
Dividend yield	0.0%

Nextest designs, develops, manufactures, sells and services low-cost, high throughput automated test equipment systems for the semiconductor industry. Nextest competes in the flash memory, flash card, and flash memory based system-on-chip (“SOC”) markets. Nextest’s products are used to test flash memory, microcontrollers, image sensors, smart cards and field programmable logic devices. The acquisition allows Teradyne to enter the flash memory test segment. Nextest is included within Teradyne’s Semiconductor Test segment.

F. ACQUISITIONS—(Continued)

The Nextest acquisition was accounted for as a purchase business combination and, accordingly, the results have been included in Teradyne’s consolidated results of operation from the date of acquisition. The allocation of the total purchase price of Nextest’s net tangible and identifiable intangible assets was based on their estimated fair values as of the acquisition date. The excess of the purchase price over the identifiable intangible and net tangible assets in the amount of $170.5 million was allocated to goodwill, which is not deductible for tax purposes. The following represents the allocation of the purchase price:

	Amount
	(in thousands)
Goodwill	$	170,492
Other intangible assets		99,800
Tangible assets acquired and liabilities assumed:
Cash and cash equivalents		88,513

Non-current assets		16,306
Accounts payable and current liabilities		(26,448	)
Other long-term liabilities		(5,542	)
In-process research and development		1,100
Total purchase price	$	399,771

Teradyne estimated the fair value of other intangible assets using the income approach. Acquired other intangible assets will be amortized on a straight-line basis over their estimated useful lives. The following table represents components of these other intangible assets and their estimated useful lives at the acquisition date:

	Fair Value		Estimated Useful Life

Technology

On March 7, 2007, Teradyne purchased in-process enabling test technology and hired certain engineers from MOSAID Technologies Inc. for $17.6 million, which included $0.6 million in fees directly related to the acquisition. Of the purchase price, $16.7 million was allocated to in-process research and development and therefore was immediately charged to the statement of operations. The balance of the purchase price was allocated to acquired workforce and fixed assets. In the year ended December 31, 2008, as a result of a workforce reduction, Teradyne recorded an impairment charge of $0.6 million to write-off the acquired workforce asset.

G. FINANCIAL INSTRUMENTS

Cash Equivalents

Teradyne considers all highly liquid investments with maturities of three months or less at the date of acquisition to be cash equivalents. Included in cash and cash equivalents are time deposits of $6.0 million and $2.7 million for the years ended December 31, 2008 and 2007, respectively.

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 held-to-maturity at December 31, 2008 or 2007. At December 31, 2008, Teradyne’s investments in auction rate securities were classified as trading securities. At December 31, 2008 and 2007, Teradyne’s investments in equity and debt mutual funds, asset backed and corporate debt securities and U.S. Treasury and government agency securities were classified as available-for-sale securities. Securities classified as available-for-sale and trading are reported at fair value. Realized gains are recorded in interest income. Realized losses and other-than-temporary unrealized losses on available-for-sale securities are included in interest expense and other. For the years ended December 31, 2008 and 2007, Teradyne recorded no realized gains on the sale of its marketable securities. For the year ended December 31, 2006, Teradyne recorded realized gains of $0.1 million on the sale of its marketable securities. For the years ended December 31, 2008, 2007, and 2006, Teradyne recorded realized losses of $5.0 million, $3.2 million and $0.3 million, respectively, on the sale of its marketable securities. Unrealized gains and losses are included in accumulated other comprehensive income (loss). The cost of securities sold is based on the specific identification method.

TERADYNE, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

G. FINANCIAL INSTRUMENTS—(Continued)

As a result of Teradyne’s November 14, 2008 acquisition of Eagle Test, Teradyne acquired $26.5 million of auction rate securities (“ARS”) at fair value ($30.0 million par value). In addition, Teradyne acquired (1) the right (“UBS Put”) to sell its ARS back to UBS at par plus interest, at its sole discretion, during a two-year period beginning on June 30, 2010, and (2) received an option to borrow up to 75% of the fair value of the ARS at no cost.

Beginning in February 2008 and continuing through December 31, 2008, the securities in Teradyne’s acquired ARS portfolio have experienced failed auctions, resulting in inability to sell these securities. Consequently, as set forth in the trust indentures, the coupon rate resets to a contractual rate which may not equal the current market rate. A failed auction results in a lack of liquidity in the securities but does not necessarily represent a deterioration of the credit quality of the issuer. All of Teradyne’s ARS, are AAA, AA or A rated by one or more of the major credit rating agencies and are substantially guaranteed by a U.S. Department of Education agency or a third party insurer. At December 31, 2008, the underlying securities for the ARS have remaining maturities ranging from five to thirty-one years. Substantially, all of these securities are collateralized by student loans. The estimated fair value of Teradyne’s ARS investments was $26.0 million as of December 31, 2008.

Because the UBS Put is expected to allow Teradyne to sell its ARS securities at par within a relatively short time horizon and provides UBS with the ability to require Teradyne to sell the securities to them at any time between acceptance of the UBS Put through July 2012, Teradyne does not anticipate holding these investments to the earlier of maturity or redemption by the issuer. Teradyne intends to exercise the UBS Put and require UBS to repurchase our ARS at par at the earliest possible time, June 2010. As a result, as of the Eagle Test acquisition date (November 14, 2008), Teradyne classified the ARS as trading securities under SFAS No. 115. During the fourth quarter of 2008, Teradyne recorded a loss of $0.5 million in interest expense and other, net for the decrease in the ARS fair value from November 14, 2008 to December 31, 2008. Future changes in fair value of the ARS will be recorded in operating results.

In determining the fair value of our ARS and other investments Teradyne utilizes the provisions of SFAS No. 157. In determining the value of our ARS as of December 31, 2008 Teradyne utilized a discounted cash flow valuation model with the major inputs to such model based on our estimates of the assumptions that market participants would use in valuing these instruments. Teradyne used the following key inputs to its valuation model:

• Term — Teradyne estimated a five-year expected life of the instruments, based on Teradyne’s expectations of the most likely time in which it would take for the instruments to be called by the issuer or liquidity to be restored to the market place.

• Probability of Default — Teradyne determined the probability of default using market credit spreads.

• Discount Rate — Teradyne determined the discount rate based on estimated yields of similar publicly traded instruments (e.g., similar collateral, terms, credit quality, etc.).

• Liquidity Risk Premium — given the recent instability in the financial markets and the low demand for auction rate securities, it is unclear as to when these securities will become liquid again. Without the auction process functioning again, it would be extremely difficult to estimate the expected holding period for these instruments. As a result, Teradyne included a 500 to 600 basis point premium to the discount rate to reflect the illiquidity of these bonds.

Based on these key inputs, Teradyne estimated the fair value of our ARS portfolio at $26.0 million as of December 31, 2008, representing a $0.5 million decrease in fair value since November 14, 2008.

G. FINANCIAL INSTRUMENTS—(Continued)

On November 14, 2008, Teradyne recognized the UBS Put as an asset measured at a fair value of $2.7 million. At December 31, 2008, the fair value of the UBS Put was $3.3 million. Teradyne recorded a $0.6 million gain in interest income during the fourth quarter of 2008 for the increase in the fair value of the UBS Put since November 14, 2008. In determining the fair value of the UBS Put as of December 31, 2008, Teradyne assumed it would redeem the auction rate securities at par at the earliest possible time, June 30, 2010. Teradyne utilized a discounted cash flow model to determine the fair value of the UBS Put using the follow assumptions (1) a time period of 1.5 years, representing the period from December 31, 2008 to the earliest date we can expect to be able to redeem the UBS Put (June 30, 2010) and (2) a discount rate of 3.79%, which included a spread based on the credit default swap of UBS in order to account for the credit risk of UBS.

Teradyne has elected fair value treatment for the UBS put under SFAS No. 159, “The Fair Value Option for Financial Assets and Financial Liabilities” (“SFAS No. 159”).

The following table sets forth by fair value hierarchy Teradyne’s financial assets and liabilities that were measured at fair value on a recurring basis as of December 31, 2008.

On a quarterly basis Teradyne reviews its investments to identify and evaluate those that have an indication of a potential other-than-temporary impairment. Factors considered in determining whether a loss is other-than-temporary include:

• The length of time and the extent to which the market value has been less than cost;

• The financial condition and near-term prospects of the issuer; and

• The intent and ability to retain the investment in the issuer for a period of time sufficient to allow for any anticipated recovery in market value.

As of December 31, 2008, the fair market value of investments with unrealized losses totaled $5.4 million. Of this value, $0.9 million had an unrealized loss for greater than one year and $4.5 million had an unrealized loss for less than one year. These investments are mutual funds related to employee retirement benefits. Teradyne reviews its investments to identify and evaluate investments that have an indication of possible impairment. Factors considered in determining whether a loss is temporary include the length of time and extent to which fair value has been less than the cost basis, the financial condition and near term prospects of the investee, and Teradyne’s intent and ability to hold the investments for a period of time to allow for anticipated recovery in market value. Based on this review, Teradyne has determined that the unrealized losses related to these investments, at December 31, 2008, are temporary.

G. FINANCIAL INSTRUMENTS—(Continued)

Derivatives

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.

To minimize the effect of exchange rate fluctuations associated with the remeasurement of net monetary assets denominated in foreign currencies, Teradyne enters into foreign currency forward contracts. The change in fair value of these derivatives is recorded directly in earnings, and is used to offset the change in fair value of the net monetary assets denominated in foreign currencies.

At December 31, 2008 and 2007, Teradyne had the following forward currency contracts to buy and sell non-U.S. currencies for U.S. dollars and other non-U.S. currencies with the following notional amounts:

	December 31, 2008								December 31, 2007
	Buy Position			Sell Position		Net Total			Buy Position			Sell Position		Net Total

Total	$	(33.7	)	$	66.3	$	32.6		$	(27.6	)	$	61.2	$	33.6

The fair value of the outstanding contracts was a loss of $0.8 million at December 31, 2008 and immaterial gain at December 31, 2007. In 2008, Teradyne recorded net realized losses of $8.1 million related to foreign currency forward contracts hedging net monetary positions. In 2007, Teradyne recorded net realized gains of $0.2 million related to foreign currency forward contracts hedging net monetary positions. In 2006, Teradyne recorded net realized gains of $2.2 million related to foreign currency forward contracts hedging net monetary positions. Both, the contract gains and losses, on the items being hedged are included in interest expense and other.

Concentration of Credit Risk

Financial instruments which potentially subject Teradyne to concentrations of credit risk consist principally of cash equivalents, marketable securities, forward currency contracts and accounts receivable. Teradyne maintains cash investments primarily in money market securities, U.S. Treasury and government agency securities, corporate debt securities and mortgage backed securities. 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 from time to time may require customers to provide a letter of credit from a bank to secure accounts receivable.

H. DEBT

Revolving Credit Facility

On November 14, 2008, in connection with the acquisition of Eagle Test, Teradyne entered into a credit agreement (the “Credit Agreement”) among Teradyne, as borrower, a syndicate of banks and certain direct and indirect domestic subsidiaries of Teradyne. The Credit Agreement provides for a senior secured revolving credit facility of $122.5 million. On November 14, 2008 and December 31, 2008, Teradyne borrowed $100 million and $22.5 million, respectively. Teradyne incurred $2.8 million in costs related to the revolving credit facility. These costs are being amortized over the three year term of the revolving credit facility.

At Teradyne’s option, loans under the Credit Agreement bear interest at a rate per annum equal to (i) the Eurodollar rate plus a margin which will vary between 3.00% and 3.50% based on Teradyne’s consolidated leverage ratio or (ii) the Base Rate, the rate of interest in effect for such day as announced by Bank of America, N.A. as its “prime rate”, plus a margin which will vary between 2.00% and 2.50% based on Teradyne’s consolidated leverage ratio. In addition, Teradyne is required to pay the Lenders a commitment fee at a rate per annum of 0.75% on the actual daily unused amount of the credit facility commitments of such Lenders during the period for which payment is made, payable quarterly in arrears. The credit facility will be available on a revolving basis until November 14, 2011. Teradyne may optionally prepay loans or reduce the credit facility commitments at any time, without penalty.

The Credit Agreement contains customary representations and warranties as well as affirmative and negative covenants. Affirmative covenants include, among others, with respect to Teradyne and its subsidiaries, maintenance of existence, financial and other reporting, payment of obligations, maintenance of properties and insurance, and an agreement to cause future material domestic subsidiaries to become parties to the Security and Pledge Agreement referred to below. Negative covenants include, among others, with respect to Teradyne and its subsidiaries, limitations on incurrence or guarantees of indebtedness, limitations on liens, sale and lease-back transactions, investments, dividends, share redemptions and other restricted payments, affiliate transactions and capital expenditures. The Credit Agreement also requires Teradyne to maintain certain financial ratios as of the end of any fiscal quarter, including a leverage ratio, fixed charge coverage ratio and an available domestic cash to total revolving borrowings ratio. The most restrictive covenant is the leverage ratio, which is a ratio of consolidated earnings before interest, taxes, depreciation and amortization (“EBITDA”) to consolidated indebtedness, which for any period of four consecutive fiscal quarters may not exceed 2.5 to 1.0, subject to certain exceptions.

The Credit Agreement contains customary events of default, including, among others, inaccuracy of representations and warranties in any material respect, non-payment of principal, interest or other amounts, violation of covenants, cross-defaults with other material indebtedness, certain undischarged judgments, the occurrence of certain ERISA or insolvency events and the occurrence of a change of control. Upon an event of default under the Credit Agreement, the Lenders may declare the loans and all other obligations under the Credit Agreement immediately due and payable. A bankruptcy or insolvency event of default causes such obligations automatically to become immediately due and payable.

The obligations of Teradyne under the Credit Agreement are guaranteed by certain domestic subsidiaries of Teradyne (“Guarantors”). As of December 31, 2008 the only Guarantors are Nextest and Eagle Test. Pursuant to a Security and Pledge Agreement, dated November 14, 2008 (the “Security and Pledge Agreement”), among Teradyne, the Guarantors and the Agent on behalf of the Lenders, the loans and the other obligations of Teradyne and the Guarantors are secured by (i) all personal property of Teradyne and each Guarantor, (ii) all present and future shares of capital stock of (or other ownership or profit interests in) each of Teradyne’s present and future

subsidiaries (limited to 65% of the capital stock of each first-tier foreign subsidiary) and (iii) all real property of Teradyne and each Guarantor, if the ratio of consolidated EBITDA to consolidated indebtedness for any period of four consecutive fiscal quarters, exceeds 2.5 to 1.0. As of December 31, 2008, Teradyne was in compliance with all financial covenants set forth in the Credit Agreement.

Convertible Senior Notes

In 2001, Teradyne issued $400 million principal amount of 3.75% Convertible Senior Notes due in 2006 (the “Notes”) in a private placement and received net proceeds of $389 million. The Notes were 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.

Teradyne began making annual interest payments of up to $15 million, paid semi-annually, on the Notes on April 15, 2002. During 2004 and 2005, we repurchased $100 million of the outstanding Notes pursuant to authorization from our Board of Directors. The decision to repurchase a portion of the Notes was based on the fair market value of the Notes being below the return we would earn on high grade investment securities. On January 26, 2006, management was given further authorization by our Board to repurchase up to the full $300 million of the principal amount that remained outstanding under the Notes through open market purchases, privately negotiated transactions and auctions for a price not to exceed 100% of the principal amount plus any accrued but unpaid interest thereon. During 2006, we repurchased Notes of $15.0 million in the first quarter, $24.0 million in the third quarter, and we repaid the remaining $261 million in the fourth quarter of 2006.

J. GOODWILL AND INTANGIBLE ASSETS

Goodwill

Teradyne performs an annual impairment test of its goodwill as required under the provisions of FAS 142 on December 31 of each fiscal year unless interim indicators of impairment exist. Goodwill is considered to be impaired when the net book value of a reporting unit exceeds its estimated fair value. Fair values are estimated using a discounted cash flow methodology.

Teradyne experienced a worsening in its demand outlook during the fourth quarter of 2008. This sharp decline is not expected to recover in the near term. Consequently, this has led to an impairment of our goodwill of $333.3 million as of December 31, 2008. In 2007 and 2006, the Company performed its annual impairment test for goodwill at the reporting unit level and determined that no adjustment to goodwill was necessary.

Aggregate intangible assets amortization expense was $20.6 million in the year ended December 31, 2008, $3.7 million in the year ended December 31, 2007, and $3.6 million in the year ended December 31, 2006. Estimated intangible assets amortization expense for each of the five succeeding fiscal years is as follows:

Teradyne determined that the worsening in its demand outlook experienced during the fourth quarter of 2008 was a significant event that indicated that the carrying amount of certain long-lived and intangible asset groups might not be recoverable. Teradyne conducted recoverability tests in accordance with SFAS No. 144. As the undiscounted future cash flows of the long-lived asset groups exceeded their carrying amount, Teradyne determined that no impairment of its long-lived assets had occurred at December 31, 2008.

Legal Claims

On July 11, 2008, Xyratex Technology, Ltd. (“Xyratex”) filed a complaint against Teradyne in the United States Federal District Court in Los Angeles, California alleging that certain Teradyne disk drive test products infringe one of Xyratex’s patents. The complaint was served to Teradyne on October 29, 2008. The suit seeks temporary, preliminary and permanent injunctive relief as well as unspecified monetary damages, including treble damages, for patent infringement. On December 17, 2008, we filed our answer and counterclaims, denying

68

TERADYNE, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

K. COMMITMENTS AND CONTINGENCIES—(Continued)

that our disk drive test products infringe the asserted Xyratex patent and asking the court to declare such patent invalid. The case is currently in the discovery phase and trial is scheduled to begin in November 2009. We intend to vigorously defend against the Xyratex claim and to vigorously pursue our counterclaims against Xyratex.

On September 5, 2001, after our August 2000 acquisition of Herco Technology Corp. and Perception Laminates, Inc., the former owners of those companies filed a complaint against Teradyne and two of our then executive officers in the Federal District Court in San Diego, California, asserting securities fraud and breach of contract related to the acquisition. The District Court dismissed certain of the plaintiffs’ claims, granted partial summary judgment against them with respect to their breach of contract claim and denied their motion for reconsideration. In July 2007, after an appeal by the plaintiffs, the U.S. Court of Appeals for the Ninth Circuit affirmed in part and reversed in part the District Court rulings. We petitioned the Ninth Circuit for rehearing, which was denied, and the case was remanded back to the District Court. On August 29, 2008, the District Court granted Teradyne’s motion for judgment on the pleadings. On September 11, 2008, the plaintiffs filed their notice of appeal.

In 2001, Teradyne was designated as a Potentially Responsible Party (“PRP”) at a clean-up site in Los Angeles, California. This claim arose out of our acquisition of Perception Laminates in August 2000. Prior to that date, Perception Laminates had itself acquired certain assets of Alco Industries Inc. under an asset purchase agreement in 1992. Neither Teradyne nor Perception Laminates have ever conducted any operations at the Los Angeles site. We have asked the State of California to drop the PRP designation, but California has not yet agreed to do so.

In November 2008, Teradyne received a general notice letter from the California Department of Toxic Substances Control (“DTSC”) which informed Teradyne of potential liability with respect to contamination at the BKK Corporation Landfill Facility Site in West Covina, California. Similar to the PRP claim discussed above, this claim arose out of our acquisition of Perception Laminates in August 2000. Neither Teradyne nor Perception Laminates have ever conducted any operations at the West Covina site. We have asked the DTSC and the group of settling defendants to remove Teradyne as a PRP for this site.

We believe that we have meritorious defenses against the above unsettled claims and intend to vigorously contest them. While it is not possible to predict or determine the outcomes of the unsettled claims or to provide possible ranges of losses that may arise, we believe the potential losses associated with all of these actions are unlikely to have a material adverse effect on our consolidated financial position, but could possibly be material to our consolidated results of operations and of cash flows of any one period.

In addition, we are subject to legal proceedings, claims and investigations that arise in the ordinary course of business such as, but not limited to, patent, employment, commercial and environmental matters. Although there can be no assurance, there are no such matters pending that we expect to be material with respect to our business, financial position or results of operations.

Guarantees and Indemnification Obligations

Teradyne provides indemnification, to the extent permitted by law, to its officers, directors, employees and agents for liabilities arising from certain events or occurrences while the officer, director, employee, or agent, is or was serving, at Teradyne’s request in such capacity. Teradyne has entered into indemnification agreements with certain of its officers and directors. With respect to acquisitions, Teradyne provides indemnifications to or assumes indemnification obligations for the current and former directors, officers and employees of the acquired companies in accordance with the acquired companies’ bylaws and charter. As a matter of practice, Teradyne has maintained directors and officer liability insurance coverage including coverage for directors and officers of

69

TERADYNE, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

K. COMMITMENTS AND CONTINGENCIES—(Continued)

acquired companies. Two former executive officers of Teradyne are named defendants in a securities case pending in the Federal District Court in San Diego, California. Each of these former executive officers has invoked the indemnification provisions described herein and insurance claims have been submitted to and are being processed by Teradyne’s director and officer liability insurance provider.

Teradyne enters into agreements in the ordinary course of business with customers, resellers, distributors, integrators and suppliers. Most of these agreements require Teradyne to defend and/or indemnify the other party against intellectual property infringement claims brought by a third party with respect to Teradyne’s products. From time to time, Teradyne also indemnifies customers and business partners for damages, losses and liabilities they may suffer or incur relating to personal injury, personal property damage, product liability and environmental claims relating to the use of Teradyne’s products and services or resulting from the acts or omissions of Teradyne, its employees, authorized agents or subcontractors. On occasion, Teradyne has also provided guarantees to customers regarding the performance of its products in addition to the warranty described below.

As a matter of ordinary business course, Teradyne warrants that its products, including software products, will substantially perform in accordance with its standard published specifications in effect at the time of delivery. Most warranties have a one year duration commencing from installation. A provision is recorded upon revenue recognition to cost of revenue for estimated warranty expense upon historical experience. When Teradyne receives revenue for extended warranties beyond the standard duration, it is deferred and recognized on a straight line basis over the contract period. Related costs are expensed as incurred. As of December 31, 2008 and 2007, Teradyne had a product warranty accrual of $8.4 million and $9.3 million, respectively, included in other accrued liabilities and revenue deferrals related to extended warranties of $6.4 million and $6.6 million, respectively, included in deferred revenue.

In addition, and in the ordinary course of business, Teradyne provides minimum purchase guarantees to certain of its vendors to ensure continuity of supply against the market demand. Although some of these guarantees provide penalties for cancellations and/or modifications to the purchase commitments as the market demand decreases, most of the guarantees do not. Therefore, as the market demand decreases, Teradyne re-evaluates these guarantees and determines what charges, if any, should be recorded.

With respect to its agreements covering product, business or entity divestitures and acquisitions, Teradyne provides certain representations, warranties and covenants to purchasers and agrees to indemnify and hold such purchasers harmless against breaches of such representations, warranties and covenants. Many of the indemnification claims have a definite expiration date while some remain in force indefinitely. With respect to its acquisitions, Teradyne may, from time to time, assume the liability for certain events or occurrences that took place prior to the date of acquisition.

As a matter of ordinary business course, Teradyne occasionally guarantees certain indebtedness obligations of its subsidiary companies, limited to the borrowings from financial institutions, purchase commitments to certain vendors, and lease commitments to landlords.

Based on historical experience and information known as of December 31, 2008, except for product warranty, Teradyne has not recorded any liabilities for these guarantees and obligations as of December 31, 2008 because the amount would be immaterial.

The computation of diluted net loss per common share for the year ended December 31, 2008 excludes all outstanding stock options and restricted stock units because Teradyne had a net loss.

The computation of diluted net income per common share for the years ended December 31, 2007 and 2006 excludes the effect of the potential exercise of options to purchase approximately 13.8 million and 15.3 million shares, respectively, because the exercise price of the option was greater than the average market price of the common shares, as the effect would have been ant-dilutive. The effect of Teradyne’s outstanding convertible notes on diluted net income per share for the year ended December 31, 2006 was calculated using the “if converted” method as required by SFAS No. 128, “Earnings per Share.” In using the “if converted” method, $8.3 million of interest expense related to the convertible notes for the year ended December 31, 2006, net of tax and profit sharing expenses, was added back to net income to arrive at diluted net income. Accordingly, 8.5 million incremental shares from the assumed conversion of the convertible debt are added to shares when calculating diluted net income per common share for the year ended December 31, 2006.

M. RESTRUCTURING AND OTHER, NET

Restructuring and Other, Net

In response to a downturn in the industry, Teradyne initiated restructuring activities across all segments to reduce costs and redundancies, principally through headcount reductions and facility consolidations. The tables below represent activity related to these actions. The remaining accrual for severance and benefits is reflected in the accrued employees’ compensation and withholdings account on the balance sheet. The remaining accrual for lease payments on vacated facilities is reflected in the other accrued liabilities account and the long-term other accrued liabilities account and is expected to be paid out over the lease terms, the latest of which expires in 2012. Teradyne expects to pay out approximately $2.4 million against the lease accruals over the next twelve months. Teradyne’s future lease commitments are net of expected sublease income of $7.7 million as of December 31, 2008. Teradyne has subleased approximately 64% of its unoccupied space as of December 31, 2008.

N. RETIREMENT PLANS

Teradyne adopted the funded status recognition provision of SFAS 158 effective December 31, 2006. This standard amends SFAS 87, 88, 106, and 132(R). SFAS 158 requires an employer with defined benefit plans or other postretirement benefit plans to recognize an asset or a liability on its balance sheet for the overfunded or underfunded status of the plans as defined by SFAS 158. The pension asset or liability represents a difference between the fair value of the pension plan’s assets and the projected benefit obligation at December 31. For other postretirement benefit plans, the liability is the difference between the fair value of the plan’s assets and the accumulated postretirement benefit obligation at December 31.

Defined Benefit Pension 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”), as well as unfunded foreign plans.

In developing the expected return on plan assets assumption, Teradyne evaluated input from its investment manager and pension consultants, including their review of asset class return expectations. Based on this review, Teradyne believes that 7.75% was an appropriate rate to use for fiscal 2008 for the U.S. Qualified Pension Plan.

TERADYNE, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

N. RETIREMENT PLANS—(Continued)

Teradyne bases its determination of pension expense or benefit on a market-related valuation of assets, which reduces year-to-year volatility. This market-related valuation recognizes investment gains or losses over a five-year period from the year in which they occur. Investment gains or losses for this purpose are the difference between the expected return calculated using the market-related value of assets and the actual return on assets. Since the market-related value of assets recognizes gains or losses over a five-year period, the future value of assets will be impacted as previously deferred gains or losses are recognized. As of December 31, 2008, under the U.S. Qualified Pension Plan, Teradyne had cumulative losses of approximately $62.5 million, which remain to be recognized in the calculation of the market-related value of assets. The discount rate that we utilized for determining future pension obligations for the U.S. Qualified Pension Plan is based on Citigroup Pension Index adjusted for the plan’s expected cash flows and was 6.2% at December 31, 2008, down from 6.5% at December 31, 2007.

Plan Assets

Teradyne’s weighted average asset allocation at December 31, 2008 and 2007, by asset category is as follows:

	United States Plan				Foreign Plans
	2008		2007		2008		2007
Equity Securities	37.0	%	46.3	%	55.1	%	53.8	%
Debt Securities	63.0		53.7		38.9		40.3
Other	—		—		6.0		5.9
Total	100.0	%	100.0	%	100.0	%	100.0	%

Teradyne employs a total return investment approach for its pension plan assets whereby a mix of equities and fixed income investments are used to ensure the preservation of capital and to maximize the long-term return of plan assets for a prudent level of risk. The investment portfolio contains a diversified blend of equity and fixed income investments. The investment portfolio will not at any time have a direct investment in Teradyne stock. It may have an indirect investment in Teradyne stock, if one of the funds selected by the investment manager invests in Teradyne stock.

The target asset allocation and index for each asset category for the U.S. Qualified Pension Plan, per policy, for the portfolio is as follows:

Asset Category:	Policy Index:	Target
Equity (Large cap)	S&P 500 Stock Index	22	%
Equity (Small cap)	Russell 2000 Index	10
International Equity	MSCI EAFE Index (Net Dividends) and MSCI Emerging Markets Free Index	15
Passive Fixed Income	Barclays Capital Long Government Credit Index	33
High-Yield Fixed Income	Barclays Capital High Yield Index	10
Real Assets	Real Asset Custom Index	10

Teradyne’s investment manager regularly reviews Teradyne’s actual asset allocation and periodically rebalances Teradyne’s portfolio to ensure alignment to the targeted allocation. The investment return objectives are to achieve a rate of return, which exceeds the rate of inflation, as measured by the Consumer Price Index, by 3% per year, and to avoid excessive volatility and produce a rate of return that at least matches the Policy Index

identified above. The manager’s investment performance is reviewed at least annually. Results for the total portfolio and for each major category of assets are evaluated in comparison with appropriate market indices, the Policy Index, other similarly managed portfolios and the Consumer Price Index. The assets of Teradyne’s foreign pension plans are invested in funds which seek to combine long-term growth potential offered through equity exposure with the relative security provided by equity, bonds and cash.

Contributions

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. During 2008, 2007 and 2006, Teradyne contributed $4.3 million, $4.8 million and $30.2 million, respectively, to the plans. Based upon the U.S. Qualified Pension Plan funded status as of December 31, 2008, Teradyne does not expect to make any contributions to this plan in 2009. Contributions that will be made in 2009 to certain Qualified Plans for non-U.S. subsidiaries are based on local statutory requirements and will be approximately $7.5 million.

Expected Future Pension Benefits Payments

The following benefit payments, which reflect future service, as appropriate, are expected to be paid as follows:

	United States		Foreign

2014-2018		93,983		15,466

Post-Retirement Benefit Plans

In addition to receiving pension benefits, U.S. Teradyne employees who meet early retirement eligibility requirements as of their termination dates may participate in Teradyne’s Welfare Plan, which includes death, and medical and dental benefits up to age 65. Death benefits provide a fixed sum to retirees’ survivors and are available to all retirees. Substantially all of Teradyne’s current U.S. employees (including executive officers) could become eligible for these benefits, and the existing benefit obligation relates primarily to those employees.

O. STOCK BASED COMPENSATION

Stock Compensation Plans

Under its stock compensation plans Teradyne granted options to purchase common stock at 100% of the fair market value on the date of grant. Options granted to employees vest in equal installments over four years and have a maximum term of seven years. Options granted to non-employee directors are immediately vested, fully exercisable and have a maximum term of either five or seven years.

Restricted stock unit awards granted to employees in 2006, 2007 and 2008 (excluding executive officers) vest in equal annual installments over four years. Restricted stock unit awards granted to non-employee directors vest after a one year period, with 100% of the award vesting on the first anniversary of the grant date. Restricted stock unit awards granted to executive officers, including the CEO, in January 2006, vest over two years. Restricted stock unit awards granted to executive officers, including the CEO, in January 2008 and 2007 vest over four years. A portion of these restricted stock unit awards granted to executive officers, including the CEO, is subject to time-based vesting and a portion of the awards is subject to performance-based vesting. The percentage level of performance satisfied for performance-based grants is assessed on or near the anniversary of the grant date and, in turn, that percentage level determines the number of performance-based restricted stock units available for vesting over the vesting period; portions of the performance-based grants not available for vesting will be forfeited. The weighted-average grant-date fair value of the restricted stock units granted in 2008, 2007 and 2006 was $9.39, $15.18, and $16.53, respectively.

Employee Stock Purchase Plan

Under the Teradyne 1996 Employee Stock Purchase Plan, eligible employees (including executive officers) may purchase shares of common stock through regular payroll deductions of up to 10% of their compensation. Under the plan, 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 and the last business day of each six month purchase period within each year. In July 2008, 0.8 million shares of common stock were issued to employees who participated in the plan during the first half of 2008, at the weighted average price of $8.55 per share. In January 2009, Teradyne issued 1.2 million shares of common stock to employees who participated in the plan during the second half of 2008, at the weighted average price of $3.59 per share.

P. SAVINGS PLAN

Teradyne sponsors an employee retirement Savings Plan covering substantially all U.S. employees. Under Teradyne’s Savings Plan, employees may contribute up to 20% of their compensation (subject to Internal Revenue Service limitations). On discretionary basis, Teradyne annually matches employee contributions up to 6% of such compensation at rates ranging from 50% to 100% for employees in the defined benefit plan. For all other employees, on discretionary basis, Teradyne annually matches up to 5% of such compensation at rates ranging from 100% to 150%. Teradyne’s contributions vest 25% per year for the first four years of employment, and contributions for those employees with four years of service vest immediately. Teradyne also has 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 the statement of operations were $7.5 million in 2008, $6.2 million in 2007 and $10.7 million in 2006.

Q. RELATED PARTY TRANSACTION

During 2007, Paul Tufano, a member of Teradyne’s Board of Directors, was Executive Vice President, Chief Financial Officer and Interim Chief Executive Officer of Solectron Corporation until it was acquired by Flextronics in October 2007. Mr. Tufano ceased being an employee of Solectron or Flextronics in October 2007. In the ordinary course of business, Teradyne has for the last ten years purchased printed circuit board assemblies from Solectron, and has also sold in-circuit testers to Solectron which Teradyne refers to as Flextronics. In August 2007, prior to the Flextronics acquisition, Teradyne expanded our contract with Solectron to have it provide additional manufacturing and test services, including areas of final configuration and test for most of Teradyne’s FLEX family of products. In the years ended December 31, 2007 and 2006, Teradyne purchased $207.8 million and $229.9 million, respectively, of printed circuit board assemblies and services from Flextronics. Sales of in-circuit testers to Flextronics for the years ended December 31, 2007 and 2006 were $4.0 million and $5.7 million, respectively. As of December 31, 2007, $19.8 million was included in accounts payable and $17.5 million was included in accounts receivable, representing amounts due to/from Flextronics.

At December 31, 2008 Teradyne had operating loss carryforwards that expire in the following years:

Total	$	193,712	$	27,936	$	132,272

Of the U.S. Federal operating loss carryforwards, $53.6 million relates to the acquisition of GenRad, Inc. in 2001. The GenRad losses are limited in the amount that can be used as a result of “change in ownership” rules as defined in the Internal Revenue Code of 1986. The net operating loss carryforward of $193.7 million includes $62.5 million of loss related to stock compensation.

Teradyne has approximately $79.3 million of tax credit carryforwards. Business tax credits of approximately $19.0 million expire in the years 2020 through 2028. Foreign tax credits of approximately $24.2 million expire in the years 2012 through 2018 and alternative minimum tax credits of approximately $7.9 million, which do not expire. In addition, there are state tax credits of $28.2 million which expire beginning in 2015.

During 2008, Teradyne’s valuation allowance decreased by $15.0 million due to the increase of the deferred tax liability related to the purchased intangible assets of $71.0 million net of the increase in the deferred tax assets of $56.0 million. The increase of deferred tax assets related to the $86 million growth in tax credits, net operating losses and pension, offset by $30 million reduction in inventory and research and development. During 2007, Teradyne’s valuation allowance decreased by $46.5 million primarily as a result of the utilization of net operating loss carryforwards against current year taxable income. Due to the continued uncertainty of realization, Teradyne maintained its valuation allowance at December 31, 2008 and 2007, for deferred tax assets in the U.S. and Singapore. Teradyne does not expect to significantly reduce its valuation allowance until sufficient positive evidence exists, including sustained profitability, that realization is more likely than not. The valuation allowance includes $51.8 million for net deferred tax assets resulting from the funded status recognition provision of SFAS 158.

For 2007 and 2006, the foreign taxes included losses generated in Singapore that were not tax affected at the U.S. federal tax rate. A corresponding valuation allowance has been established in Singapore for these losses.

Teradyne adopted FIN 48, “Accounting for Uncertainties in Income Taxes” (“FIN 48”) effective January 1, 2007. FIN 48 applies to all income tax positions accounted for under FASB Statement No. 109, “Accounting for Income Taxes”, and addresses the determination of whether tax benefits claimed or expected to be claimed on a tax return should be recorded in the financial statements. FIN 48 also addressed other aspects of reporting and disclosing uncertain tax positions. Upon adoption of FIN 48, there was no cumulative effect to retained earnings. It is anticipated that within the next twelve months there will be no change in unrecognized tax benefits. As of December 31, 2008, Teradyne has open tax years beginning in 2003 for major jurisdictions including the U.S., Japan, Singapore and the United Kingdom. Teradyne records all interest and penalties related to income taxes as a component of income tax expense. Accrued interest and penalties related to income tax items at December 31, 2008 were not material.

Teradyne’s unrecognized tax benefits for the years 2008 and 2007 are as follows (in thousands):

	2008			2007
Beginning balance, as of January 1	$	9,780		$	10,584

R. INCOME TAXES—(Continued)

Current year and prior year additions include assessment of potential transfer pricing issues worldwide. Reductions for tax positions for prior years relate to changes in estimates regarding the limitations of foreign tax credits and acquired net operating losses. Settlements with tax authorities in 2007 relate to the closing of transfer pricing issues with local tax authorities in Europe and Asia. Of the $11.1 million of unrecognized tax benefits as of December 31, 2008, $8.4 million would impact the consolidated income tax rate if ultimately recognized. The remaining $2.7 million would impact the valuation allowance if recognized.

As of December 31, 2008, a deferred tax liability has not been established for approximately $245.7 million of cumulative undistributed earnings of non-U.S. subsidiaries, as Teradyne plans to keep these amounts permanently reinvested overseas. Beginning in 2006, Teradyne received from Singapore tax incentives for earnings from investments and related activities that began in that country in 2005. These incentives extend through 2019. From 2003 through 2006, Teradyne received tax incentives to conduct business in the People’s Republic of China.

S. OPERATING SEGMENT AND GEOGRAPHIC INFORMATION

Teradyne’s two reportable segments are Semiconductor Test and Systems Test Group. The Semiconductor Test segment includes operations related to the design, manufacturing and marketing of semiconductor test products and services. The Systems Test Group segment includes operations related to the design, manufacturing and marketing of circuit-board test and inspection products and services, military/aerospace instrumentation test products and services, and automotive diagnostic and test products and services.

During the third quarter of 2007, the internal management reporting of Teradyne changed to better align with the company’s operational management structure, resulting in a change in Teradyne’s reportable segments. Segment reporting has been restated for all periods presented to reflect this change. Each reportable segment has one segment president who reports directly to the chief operating decision maker and the segments reporting presented reflects the information reviewed and used by the chief operating decision maker.

Teradyne evaluates performance using several factors, of which the primary financial measure is business segment income from continuing operations before taxes. The accounting policies of the business segments are the same as those described in Note B: “Accounting Policies”. Due to the sale on August 1, 2007 of Broadband Test Division, its results have been excluded from segment reporting and included in discontinued operations for all periods presented. Previously, Broadband Test Division and Diagnostic Solutions had been combined to form the Other Test Systems segment.

Item 9: Changes in and disagreements with accountants on accounting and financial disclosure

None.

Item 9A: Controls and procedures

Disclosure Controls and Procedures

As of the end of the period covered by this report, our management, with the participation of our CEO and CFO, evaluated the effectiveness of our disclosure controls and procedures pursuant to Rule 13a-15(b) promulgated under the Exchange Act. Based upon that evaluation, our CEO and CFO concluded that, as of the end of the period covered by this report, our disclosure controls and procedures were effective in ensuring that material information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, including ensuring that such material information is accumulated and communicated to our management, including our CEO and CFO, as appropriate to allow timely decisions regarding required disclosure.

Changes in Internal Control Over Financial Reporting

There was no change in our internal control over financial reporting during the fourth fiscal quarter ended December 31, 2008 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Management’s Annual Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rule 13a-15(f). Under the supervision and with the participation of our management, including our CEO and CFO, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on our evaluation under the framework in Internal Control—Integrated Framework, our management concluded that our internal control over financial reporting was effective as of December 31, 2008.

The audited consolidated financial statements of Teradyne include the results of Nextest Systems Corporation and Eagle Test Systems, Inc., which Teradyne acquired in the year ended December 31, 2008. Management has excluded Nextest Systems Corporation and Eagle Test Systems from its assessment of internal control over financial reporting as of December 31, 2008 because they were acquired by Teradyne in purchase business combinations during 2008. Nextest Systems Corporation and Eagle Test Systems are wholly-owned subsidiaries whose total assets represent 4% and 6%, respectively, and total revenues represent 7% and 1%, respectively, of the related consolidated financial statement amounts as of and for the year ended December 31, 2008.

The effectiveness of our internal control over financial reporting as of December 31, 2008 has been audited by PricewaterhouseCoopers LLP, our independent registered public accounting firm, as stated in their report which is included under Item 8 of this Annual Report.

97

Inherent Limitations on Effectiveness of Controls

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
