Products

Semiconductor Test

We design, manufacture, sell and support Semiconductor Test products and services on a worldwide 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 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 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 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 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, Foundries 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.

	(in millions)
Semiconductor Test	$	274.8	$	334.2
Systems Test Group		175.3		152.0
Wireless Test		4.4		—

	$	454.5	$	486.2

Of the backlog at December 31, 2011, approximately 99% of the Semiconductor Test backlog, 91% of Systems Test Group backlog, and 100% of Wireless Test backlog, is expected to be delivered in 2012.

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, 2011, we employed approximately 3,200 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, 2011, 2010 and 2009 were $195.6 million, $193.0 million, and $161.3 million, respectively. These expenditures amounted to approximately 14%, 12%, and 21% of consolidated net revenue in 2011, 2010, and 2009, respectively.

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 environmental remediation laws and regulations.

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 experienced disruption in 2009 and 2008, 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. We are unable to predict the likely duration and severity of 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. Disruption and deterioration in economic conditions may reduce customer purchases of our products, thereby reducing our revenues and earnings. In addition, such adverse decline in economic conditions may, among other things, result in increased price competition for our products, increased risk of excess and obsolete 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 have taken actions to address the effects of the economic crisis, including implementing cost control and reduction measures. If our business has another downturn, we may need to take further cost control and reduction measures.

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 2009 and 2008 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 ensure that the level of revenues or new orders for a fiscal 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.

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 emerging Asian equipment companies and internal development 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.

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:

•

a worldwide economic slowdown or disruption in the global financial markets;

•

competitive pressures on selling prices;

•

our ability to introduce, and the market acceptance of, new products;

•

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

•

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, 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;

•

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 continues to increase.

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 or acquisition 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 or acquisition, introduction and acceptance depend upon a number of factors, including:

•

new product selection;

•

ability to meet customer requirements;

•

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 dependent upon the ability of our suppliers and contractors to help meet increased product or delivery requirements. It may be difficult for certain 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 and on other contract manufacturers to manufacture other products. If for any reason these contract manufacturers 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 or our other contract manufacturers, 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 effect on our operations which could result in a decline in our stock price.

We may not fully realize the benefits of our acquisitions or strategic alliances.

In October 2011, we acquired LitePoint Corporation (“LitePoint”). We may not be able to realize the benefit of acquiring LitePoint or successfully grow LitePoint’s business. 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 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. Following an acquisition, we may not 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 have increased our indebtedness.

On April 6, 2009, we completed a registered underwritten offering of $190.0 million aggregate principal amount of 4.50% Convertible Senior Notes (the “Notes”) due March 15, 2014 and received net proceeds of approximately $163.0 million. We used approximately $123.3 million of the net proceeds of this offering to repay all amounts outstanding under our revolving credit facility. Although we are no longer subject to the restrictive covenants under the revolving credit facility, we have incurred approximately $190.0 million principal amount of new indebtedness that the holders of the Notes may require us to repurchase upon the occurrence of certain fundamental changes involving the Company. In addition, on March 31, 2009, our wholly-owned subsidiary in Japan, Teradyne K.K., incurred approximately $10.0 million in indebtedness that we guaranteed. The level of our indebtedness, among other things, could:

•

make it difficult to make payments on our other obligations;

•

make it difficult to obtain any necessary future financing for working capital, capital expenditures, debt service requirements or other purposes;

•

require the dedication of a substantial portion of any cash flow from operations to service for indebtedness, thereby reducing the amount of cash flow available for other purposes, including capital expenditures; and

•

limit our flexibility in planning for, or reacting to, changes in our business and the industries in which we compete.

Our convertible note hedge and warrant transactions could impact the value of our stock.

Concurrent with the offering of the Notes, we entered into a convertible note hedge transaction with Goldman, Sachs & Co. (the “hedge counterparty”) with a strike price equal to the initial conversion price of the Notes. The convertible note hedges cover, subject to customary antidilution adjustments, approximately 34,703,196 shares of our common stock.

Separately and concurrent with the pricing of the Notes, we entered into a warrant transaction with the hedge counterparty with a strike price of $7.67 per share, which was 75% higher than the closing price of our common stock on March 31, 2009. The warrants will be net share settled and cover, subject to customary antidilution adjustments, approximately 31,963,470 shares of our common stock. On April 1, 2009, the hedge counterparty exercised its option to purchase warrants covering, subject to customary antidilution adjustments, an additional 2,739,726 shares of our common stock. However, we will not be obligated to deliver to the hedge counterparty more than 34,526,500 shares of common stock upon exercise of the warrants (which amount represented less than 19.99% of our outstanding shares of common stock as of March 31, 2009, without giving effect to any shares of common stock issuable pursuant to the warrant transaction), subject to customary antidilution adjustments.

The convertible note hedges are expected to reduce the potential dilution to our common stock upon any conversion of the Notes. However, the warrant transaction could separately have a dilutive effect to the extent

that the market value per share of our common stock exceeds the applicable strike price of the warrant. The net cost of the convertible note hedge transaction to us, after being partially offset by the proceeds from the sale of the warrants, was approximately $21.7 million.

In connection with establishing its initial hedge of these convertible note hedge and warrant transactions, the hedge counterparty has entered into various derivative transactions with respect to our common stock and/or purchased shares of our common stock or other securities, including the Notes, concurrent with, or shortly after, the pricing of the Notes. In addition, the hedge counterparty may modify its hedge positions by entering into or unwinding various derivative transactions with respect to our common stock or by selling our common stock or other securities, including the Notes, in secondary market transactions (and may do so during any observation period related to the conversion of the Notes). These activities could adversely impact the value of our common stock and the Notes.

We have taken measures to significantly lower our fixed costs, 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 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 the number of our employees, and reducing planned capital expenditures and expense budgets. We cannot ensure 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 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 cost, 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, 2011, 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.

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 have been sued for patent infringement in the past and 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 product or it could force us to seek a license to the intellectual property rights of others or alter such products 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 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 effect on our financial condition and operating results.

We may incur higher tax rates than we expect and may have exposure to additional international tax liabilities and costs.

We are subject to paying income taxes in the United States and various other countries where we operate. Our effective tax rate is dependent on where our earnings are generated and the tax regulations and the interpretation and judgment of administrative tax or revenue entities in the United States and other countries. We have pursued a global tax strategy which could adversely be affected by our failure to expand operations or earnings in certain countries, the mix of earnings and tax rates in the countries where we operate, changes to tax laws or an adverse tax ruling by administrative entities. We are also subject to tax audits in the countries where we operate. Any material assessment resulting from an audit from an administrative tax or revenue entity could also negatively affect our financial results.

As a multinational corporation, we are subject to income taxes as well as non-income based taxes, in both the United States and various foreign jurisdictions. In certain foreign jurisdictions, we qualify for tax incentives based on our ability to meet, on a continuing basis, various tests relating to our employment levels, research and development expenditures and other qualification requirements in a particular foreign jurisdiction. While we intend to operate in such a manner to maintain and maximize our tax incentives, no assurance can be given that we have so qualified or that we will so qualify for any particular year or jurisdiction. If we fail to qualify and to remain qualified for certain foreign tax incentives, we may be subject to further taxation or an increase in our effective tax rate which would adversely impact our financial results. In addition, we may incur additional costs, including headcount expenses, in order to obtain or maintain a foreign tax incentive in a particular foreign jurisdiction.

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 J: “Commitments and Contingencies—Guarantees and Indemnification Obligations” in Notes to Consolidated Financial Statements.

If we are unable to protect our intellectual property (“IP”), 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 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.

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 ability 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.

We may have additional pension funding obligations as a result of the weak performance of financial markets and its effect on plan assets.

Our future funding obligations for our U.S. defined benefit pension plan qualified with the Internal Revenue Service (“IRS”) depend upon the future performance of assets for this plan, the level of interest rates used to determine funding levels, the level of benefits provided for by the plan and any changes in government laws and regulations. Our U.S. qualified defined benefit pension plan currently holds a significant amount of fixed income securities. As of December 31, 2011, our U.S. qualified defined benefit pension plan had a funded status of approximately 102%. Due to significant declines in financial markets and deterioration in the value of our plan assets in 2008, we made additional discretionary contributions to our U.S. qualified defined benefit pension plan in 2009 and 2010 and may have to make additional contributions in future reporting periods, which may negatively affect our cash flow.

The natural disasters in Japan and the Philippines could disrupt our operations and those of our customers and adversely affect our results of operations.

The recent events in Japan and the Philippines, including earthquakes, tsunamis, flooding and the related damage, created economic uncertainty in those countries. Based on a review of our global supply chain and the customers’ test facilities we serve in Japan and the Philippines, we do not expect a significant impact on our ability to manufacture and sell our products, however, there can be no assurance that an adverse effect on our business, financial condition and operating results will not result from these events.

Our operations and the operations of our customers and suppliers are subject to risks of natural catastrophic events, widespread health epidemics, acts of war, terrorist attacks and the threat of domestic and international terrorist attacks, any one of which could result in cancellation of orders, delays in deliveries or other business activities, or loss of customers and could negatively affect our business and results of operations.

Our business is international in nature, with our sales, service and administrative personnel and our customers and suppliers located in numerous countries throughout the world. Our operations and those of our customers and suppliers are subject to disruption for a variety of reasons, including work stoppages, acts of war, terrorism, health epidemics, fires, earthquakes, hurricanes, volcanic eruptions, energy shortages, telecommunication failures, tsunamis, flooding or other natural disasters. Such disruption could materially increase our costs and expenses as well as cause delays in, among other things, shipments of products to our customers, our ability to perform services requested by our customers, or the installation and acceptance of our products at customer sites. Any of these conditions could have a material adverse effect on our business, financial conditions and results of operations.

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

There are 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.

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. We believe that we have meritorious defenses against all pending claims and intend to vigorously contest them. While it is not possible to predict or determine the outcomes of any pending 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 business, financial position or results of operations.

Management’s Discussion and Analysis of Financial Condition and Results of Operations

Statements in this Annual Report on Form 10-K which are not historical facts, so called “forward looking statements,” are made pursuant to the safe harbor provisions of Section 21E of the Securities Exchange Act of 1934, as amended. Investors are cautioned that all forward looking statements involve risks and uncertainties, including those detailed in Teradyne’s filings with the Securities and Exchange Commission. Readers are cautioned not to place undue reliance on these forward-looking statements which reflect management’s analysis only as of the date hereof. We assume no obligation to update these forward-looking statements to reflect actual results or changes in factors or assumptions affecting forward-looking statements, except as may be required by law.

Overview

We are a leading global supplier of automatic test equipment. We design, develop, manufacture, and sell automatic test systems and solutions used to test complex electronics in the consumer electronics, automotive, computing, telecommunications, wireless, and aerospace and defense industries. Our automatic test equipment products and services include:

•

semiconductor test (“Semiconductor Test”) systems; and

•

military/aerospace (“Mil/Aero”) test instrumentation and systems, storage test systems (“Storage Test”), circuit-board test and inspection (“Commercial Board Test”) systems, collectively these products represent “Systems Test Group”; and

•

wireless test (“Wireless Test”) systems.

The sales of our products and services are dependent, to a large degree, on customers who are subject to cyclical trends in the demand for their products. These cyclical periods have had, and will continue to have, a significant effect on our business since our customers often delay or accelerate purchases in reaction to changes in their businesses and to demand fluctuations in the semiconductor industry. Historically, these demand fluctuations have resulted in significant variations in our results of operations. This was particularly relevant beginning in the fourth quarter of fiscal year 2008 where we saw a significant decrease in revenue in our Semiconductor Test business which was impacted by the deteriorating global economy, which negatively impacted the entire semiconductor industry. The sharp swings in the semiconductor industry in recent years have generally affected the semiconductor test equipment and services industry more significantly than the overall capital equipment sector.

We believe our acquisitions of Nextest, Eagle Test and LitePoint, and our entry into the high speed memory and storage test markets have enhanced our opportunities for growth. We will continue to invest in our business to expand further our addressable markets while tightly managing our costs.

We regularly face price competition in each of our businesses. More recently, we have been subject to greater price competition in the Semiconductor Test segment. We intend to respond to competitive pricing moves as necessary, which may adversely impact our gross margins. Longer term, we will continue to invest in engineering to lower the cost of test which should help mitigate the impacts from aggressive pricing actions.

On March 21, 2011, we completed the sale of our Diagnostic Solutions business unit, which was included in the Systems Test Group segment, to SPX Corporation for $40.2 million in cash. We sold this business as its growth potential as a stand-alone business was significantly less than if it was part of a larger automotive supplier. The financial information for Diagnostic Solutions has been reclassified to discontinued operations.

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.

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, deferred tax assets, 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

In October 2009, FASB amended the accounting standards for revenue recognition to remove tangible products containing non-software and software components that function together to deliver the product’s essential functionality from the scope of industry-specific software revenue recognition guidance. In October 2009, the FASB also amended the accounting standards for arrangements with multiple deliverables. We elected to early adopt this accounting guidance at the beginning of our first quarter of 2010 on a prospective basis. Adoption had no material impact on our financial position or results of operations in 2010 and 2011.

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 has non-software and software components that function together to deliver the equipment’s essential functionality. 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. We also defer the portion of the sales price that is not due until acceptance, which represents deferred profit.

For multiple element arrangements, we allocate revenue to all deliverables based on their relative selling prices. In such circumstances, a hierarchy is used to determine the selling price for allocating revenue to deliverables as follows: (i) vendor-specific objective evidence of selling price (“VSOE”), (ii) third-party evidence of selling price (“TPE”), and (iii) best estimate of the selling price (“BESP”). For a delivered item to be considered a separate unit, the delivered item must have value to the customer on a standalone basis and the delivery or performance of the undelivered item must be considered probable and substantially in our control.

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 days of product shipment and is completed within one to two days thereafter. Training services are optional and do not

affect the customers’ ability to use the product. We defer revenue for the selling price of installation and training. Extended warranties constitute warranty obligations beyond one year and we defer revenue in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 605-20, “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, revenue is recognized in accordance with ASC 985-605, “Software Revenue Recognition.” We recognize revenue when there is persuasive evidence of an arrangement, delivery has occurred, the sales price is fixed or determinable and collectability is probable. In instances where an arrangement contains multiple elements, revenue related to the undelivered elements is deferred 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 ASC 605-35, “Revenue Recognition Construction-Type and 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

Stock-based compensation expense is based on the grant-date fair value estimated in accordance with the provisions of ASC 718-10 “Compensation—Stock Compensation”. As required by ASC 718-10, we have made an estimate of expected forfeitures and are recognizing compensation costs only for those stock-based compensation awards expected to vest.

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. We consider the probability of future taxable income and our historical profitability, among other factors, in assessing the amount of the valuation allowance. As a result of this review, undertaken at December 31, 2002, we concluded under 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. At December 31, 2011, we reassessed this judgment and concluded

that it is more likely than not that a substantial majority of our deferred tax assets will be realized through consideration of both the positive and negative evidence. The evidence consisted primarily of our three year U.S. historical cumulative profitability, projected future taxable income, forecasted utilization of the deferred tax assets and the fourth quarter of 2011 acquisition of LitePoint offset by the volatility of the industries we operate in, primarily the semiconductor industry. As such, we reduced the valuation allowance by $190.2 million, which was recorded as a tax benefit in the year ended December 31, 2011. We maintain a valuation allowance for certain deferred tax assets of $51.1 million, primarily related to excess stock compensation deductions associated with pre-2006 activity, state net operating losses and state tax credit carryforwards, due to uncertainty regarding their realization. Adjustments could be required in the future if we estimate that the amount of deferred tax assets to be realized is more or less than the net amount we have recorded.

Investments

We account for our investments in debt and equity securities in accordance with the provisions of ASC 320-10, “Investments—Debt and Equity Securities.” 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.

Goodwill, Intangible and Long-Lived Assets

In September 2011, the FASB issued ASU No. 2011-08, “Intangibles-Goodwill and Other (Topic 350): Testing Goodwill for Impairment.” This new guidance is intended to simplify goodwill impairment testing by allowing companies to first assess qualitative factors to determine if it is more likely than not that goodwill might be impaired and whether it is necessary to perform the current two-step goodwill impairment test. We adopted this guidance in the fourth quarter of 2011 and determined that it is not more likely than not that the fair value of our reporting unit is less than its carrying value.

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.

Revenues

Net revenues for our three reportable segments were as follows:


	2011		2010		2009		2010-2011 Dollar Change			2009-2010 Dollar Change
	(in millions)
Semiconductor Test	$	1,106.2	$	1,413.3	$	552.4	$	(307.1	)	$	860.9
Systems Test Group		294.5		152.9		225.0		141.6			(72.1	)
Wireless Test		28.4		—		—		28.4			—

	$	1,429.1	$	1,566.2	$	777.4	$	(137.1	)	$	788.8

Semiconductor Test revenue decreased $307.1 million or approximately 22% from 2010 to 2011, due to a decrease in system-on-a-chip (“SOC”) product sales. Semiconductor Test product demand can fluctuate significantly from year to year based upon semiconductor device unit growth and installed base utilization. The 2011 decrease was due to lower volume from reduced demand.

Semiconductor Test revenue increased $860.9 million or approximately 156% from 2009 to 2010, due to a strong recovery in the semiconductor market, particularly in SOC test, and due to our strong market share in the higher growth Semiconductor Test segments such as power management, wireless and microcontroller.

The increase in Systems Test Group revenue of $141.6 million or approximately 93% from 2010 to 2011 was primarily due to the increase in sales of Storage Test systems, which was driven by new customers and new product applications.

The decrease in Systems Test Group revenue of $72.1 million or approximately 32% from 2009 to 2010 was primarily due to the decrease in sales of Storage Test systems and Mil/Aero systems and instruments, partially offset by an increase in Commercial Board Test sales.

The acquisition of LitePoint which was completed in October of 2011 added $28.4 million of revenue in 2011. Litepoint is our Wireless Test segment.

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


	2011			2010			2009
Semiconductor Test		77	%		90	%		71	%
Systems Test Group		21			10			29
Wireless Test		2			—			—

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


	2011		2010		2009		2010-2011 Dollar Change			2009-2010 Dollar Change
	(in millions)
Product Revenue	$	1,160.2	$	1,331.0	$	576.5	$	(170.8	)	$	754.5
Service Revenue		268.9		235.2		200.9		33.7			34.3

	$	1,429.1	$	1,566.2	$	777.4	$	(137.1	)	$	788.8

Our product revenue decreased $170.8 million or 13% in 2011 from 2010 primarily due to lower sales of SOC Semiconductor Test products. Semiconductor Test product sales demand can fluctuate significantly from year to year based upon semiconductor device unit growth and installed base utilization. The 2011 decrease was due to lower volume from reduced demand. The decrease was partially offset by an increase in sales of Storage Test systems, which was driven by new customers and new product applications. The LitePoint acquisition which was completed in October of 2011 added $27.8 million of product revenue in 2011. 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 $33.7 million or 14% due to higher volume.

Our product revenue increased $754.5 million or 131% in 2010 from 2009 primarily due to higher sales across all Semiconductor Test products. The increase was partially offset by a decrease in sales of Storage Test systems and Mil/Aero systems and instruments. Service revenue increased $34.3 million or 17%, due to higher volume.

In fiscal year 2011 and 2010, no single customer accounted for more than 10% of our consolidated net revenue. In 2009, revenues from one customer accounted for 13% of our consolidated net revenue. In each of the years 2011, 2010 and 2009, our three largest customers in aggregate accounted for 19%, 21% and 27% of our consolidated net revenue, respectively.

Gross Profit


	2011			2010			2009			2010-2011 Dollar / Point Change			2009-2010 Dollar / Point Change
	(dollars in millions)
Gross Profit	$	713.7		$	856.0		$	299.4		$	(142.3	)	$	556.6
Percent of Total Revenue		49.9	%		54.7	%		38.5	%		(4.8	)		16.2

Gross profit as a percentage of revenue decreased from 2010 to 2011 by 4.8 percentage points. This decrease was the result of a decrease of 2.9 points related to product mix primarily from higher Storage Test system sales, a decrease of 0.9 points for a charge to adjust LitePoint acquired inventory to fair value, a decrease of 0.5 points due to lower volume, and a decrease of 0.3 points due to higher inventory provisions.

Gross profit as a percentage of revenue increased from 2009 to 2010 by 16.2 percentage points. This increase in gross profit was the result of an increase of 8.9 points due to higher product sales volume, an increase of 6.6 points related to product mix and an increase of 1.8 points due to lower inventory provisions. These increases were partially offset by a decrease of 1.2 points primarily due to higher variable compensation.

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


	2011			2010			2009			2010-2011 Dollar / Point Change			2009-2010 Dollar / Point Change
	(dollars in millions)
Product Gross Profit	$	583.1		$	739.5		$	205.6		$	(156.4	)	$	533.9
Percent of Product Revenue		50.3	%		55.6	%		35.7	%		(5.3	)		19.9

Service Gross Profit	$	130.6		$	116.5		$	93.8		$	14.1		$	22.7
Percent of Service Revenue		48.6	%		49.5	%		46.7	%		(0.9	)		2.8

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.

During the year ended December 31, 2011, we recorded an inventory provision of $11.6 million included in cost of revenues, due to the downward revisions to previously forecasted demand levels. Of the $11.6 million of total excess and obsolete provisions recorded in 2011, $10.4 million was related to Semiconductor Test primarily due to product transition, $1.1 million was related to Systems Test Group, and $0.1 million was related to Wireless Test.

During the year ended December 31, 2010, we recorded an inventory provision of $6.0 million included in cost of revenues, due to the downward revisions to previously forecasted demand levels. Of the $6.0 million of total excess and obsolete provisions recorded in 2010, $4.5 million was related to Semiconductor Test and $1.5 million was related to Systems Test Group.

During the year ended December 31, 2009, we recorded an inventory provision of $24.8 million included in cost of revenues, due to the following factors:

—

Downward revisions to previously forecasted demand levels as a result of worsening economic conditions experienced in the semiconductor and automotive industries primarily in the first half of 2009 resulted in an inventory provision of $13.5 million for inventory not expected to be consumed;

—

A decline in demand versus forecast for our Liquid Crystal Display (“LCD”) test product due to the global economic downturn, lower product pricing by competitors, the introduction of a new product by a competitor and consolidation among a number of the expected buyers of the product, resulted in an inventory provision of $8.6 million; and

—

During late 2008, we introduced the next versions of our Nextest Magnum memory test product. At that time, it was anticipated that demand would continue for the existing version of the product within its installed base of customers. An overall decline in the memory market combined with a portion of our customers accelerating their purchasing of the newer version of the product resulted in an inventory provision of $2.7 million.

Of the $24.8 million of total excess and obsolete provisions recorded in 2009, $20.3 million was related to Semiconductor Test and $4.5 million was related to Systems Test Group.

During the year ended December 31, 2011, 2010 and 2009, we scrapped $9.2 million, $4.7 million and $29.6 million of inventory, respectively, and sold $8.1 million, $8.3 million and $4.3 million of previously written-down or written-off inventory, respectively. As of December 31, 2011, we had inventory related reserves for amounts which had been written-down or written-off totaling $123.5 million. We have no pre-determined timeline to scrap the remaining inventory.

Engineering and Development

Engineering and development expenses were as follows:


	2011			2010			2009			2010-2011 Change		2009-2010 Change
	(dollars in millions)
Engineering and Development	$	195.6		$	193.0		$	161.3		$	2.6	$	31.7
Percent of Total Revenue		13.7	%		12.3	%		20.8	%

The increase of $2.6 million in engineering and development expenses from 2010 to 2011 was due primarily to additional costs of $6.0 million related to the acquisition of LitePoint in October 2011, partially offset by lower variable compensation.

The increase of $31.7 million in engineering and development expenses from 2009 to 2010 was due primarily to an $18.6 million increase in variable compensation and $6.2 million increase from the restoration of temporary salary reductions.

Selling and Administrative

Selling and administrative expenses were as follows:


	2011			2010			2009			2010-2011 Change		2009-2010 Change
	(dollars in millions)
Selling and Administrative	$	233.7		$	226.8		$	195.4		$	6.9	$	31.4
Percent of Total Revenue		16.4	%		14.5	%		25.1	%

The increase of $6.9 million in selling and administrative expenses from 2010 to 2011 was due primarily to additional costs of $9.7 million related to the acquisition of LitePoint in October 2011, partially offset by lower variable compensation.

The increase of $31.4 million in selling and administrative expenses from 2009 to 2010 was due primarily to a $25.1 million increase in variable compensation and $9.9 million from the restoration of temporary salary reductions, partially offset by a $5.3 million decrease in other spending related to workforce reductions and other cost reduction initiatives taken in 2009.

Acquired Intangible Assets Amortization

Acquired intangible assets amortization expense was as follows:


	2011			2010			2009			2010-2011 Change		2009-2010 Change
	(dollars in millions)
Acquired Intangible Assets Amortization	$	40.5		$	29.3		$	32.3		$	11.2	$	(3.0	)
Percent of Total Revenue		2.8	%		1.9	%		4.2	%

Acquired intangible assets amortization expense increased from 2010 to 2011 due to the LitePoint acquisition which was completed in October of 2011.

Acquired intangible assets amortization expense decreased from 2009 to 2010 because intangible assets related to the 2001 GenRad acquisition were fully amortized in 2009.

Restructuring and Other

Restructuring

In response to a downturn in the industry in 2008 and 2009, we implemented restructuring activities across all segments to reduce costs, principally through headcount reductions and facility consolidations. The remaining accrual for severance and benefits of $0.3 million is reflected in the accrued employees’ compensation and withholdings account on the balance sheet and is expected to be paid by July 2012. The remaining accrual for lease payments on vacated facilities of $1.9 million 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 approximately $0.9 million against the lease accruals over the next twelve months. Our future lease commitments, as of December 31, 2011, are net of expected sublease income of $0.5 million. As of December 31, 2011, we have subleased approximately 37% of our unoccupied space.

During the year ended December 31, 2011, we recorded the following restructuring activities:

Q1 2011 Actions:

–

$4.6 million related to LitePoint acquisition costs; and

–

$2.7 million related to non-U.S pension settlements.

During the year ended December 31, 2009, we recorded $(1.0) million of other net credits related to the following:

–

$1.1 million of long-lived asset impairment charges across both segments primarily related to the disposal of fixed assets as a result of the consolidation of facilities in North Reading, Massachusetts;

–

$(2.0) million of credits related to finalization of certain Eagle Test purchase accounting items; and

Interest and Other


	2011			2010			2009			2010-2011 Change		2009-2010 Change
	(in millions)
Interest income	$	6.6		$	5.9		$	3.4		$	0.7	$	2.5
Interest expense and other, net	$	(23.7	)	$	(24.5	)	$	(22.4	)	$	0.8	$	(2.1	)

Interest income increased by $0.7 million, from $5.9 million in 2010 to $6.6 million in 2011, due primarily to higher cash and marketable securities balances in 2011.

Interest income increased by $2.5 million, from $3.4 million in 2009 to $5.9 million in 2010, due primarily to a gain on sale of auction rate securities.

Interest expense and other decreased by $0.8 million, from $24.5 million in 2010 to $23.7 million in 2011, due primarily to a loss on the exercise of the auction rate securities related UBS Put recorded in 2010, partially offset by higher convertible debt discount amortization in 2011.

Interest expense and other increased by $2.1 million, from $22.4 million in 2009 to $24.5 million in 2010, due primarily to a $6.0 million increase in interest expense related to our convertible senior notes and a loss of $2.7 million on the exercise of the auction rate security related UBS Put. In 2009, interest expense and other included $2.5 million for the write off of the remaining revolving credit facility issue costs due to the termination of our revolving credit facility agreement, $2.1 million in interest expense related to the revolving credit facility, and $2.8 million realized loss on sale and impairment of marketable securities.

The decrease in income from continuing operations before income taxes from 2010 to 2011 was primarily due to lower revenue in 2011 compared to 2010, an $11.2 million increase in intangible assets amortization, a $12.2 million charge to adjust LitePoint acquired inventory to fair value and a $9.0 million increase in restructuring and other costs.

The increase in income from continuing operations before income taxes from 2009 to 2010 was primarily due to higher revenue in 2010 compared to 2009 and lower restructuring and other costs in 2010.

Income Taxes

The income tax benefit from continuing operations for 2011 totaled $129.3 million, primarily attributable to the reduction of our deferred income tax valuation allowance. We considered the weight of both the positive and negative evidence as of December 31, 2011 and concluded that a substantial majority of the deferred tax assets will be realized. The income tax expense from continuing operations of $14.5 million for 2010 was related primarily to tax provisions for foreign taxes. The income tax benefit from continuing operations of $8.5 million for 2009 was primarily due to federal net operating loss carryback claims.

Contractual Obligations

Included in Other Long-Term Liabilities are liabilities for customer advances, extended warranty, uncertain tax positions and other obligations. For certain long-term obligations, we are unable to provide a reasonably reliable estimate of the timing of future payments relating to these obligations and therefore we included these amounts in the column marked “Other”.

Liquidity and Capital Resources

Our cash, cash equivalents and marketable securities balance decreased $300.8 million in 2011 from 2010 to $754.6 million. Cash activity for 2011, 2010 and 2009 was as follows:


	2011			2010			2009			2010-2011 Change			2009-2010 Change

In 2011, changes in operating assets and liabilities, net of businesses sold and acquired, used cash of $94.0 million. This was due to a $43.2 million decrease in operating assets and a $137.2 million decrease in operating liabilities.

The decrease in operating assets was due to a $66.4 million decrease in accounts receivable resulting from increased collections, partially offset by a $22.6 million increase in prepayments due primarily to supplier prepayments and a $0.6 million increase in inventories. The decrease in operating liabilities was due to a $62.6 million decrease in customer advance payments due to shipments of systems prepaid by customers, a $28.3 million decrease in accrued employee compensation due primarily to variable compensation payments, a $19.9 million decrease in accounts payable due to decreased sales volume, $11.9 million of retirement plan contributions, a $8.7 million decrease in accrued income taxes, and a $5.8 million decrease in deferred revenue.

Investing activities during 2011 used cash of $120.5 million. In October 2011, we completed the acquisition of LitePoint for an initial cash purchase price, net of cash acquired, of $537.5 million. Capital expenditures were $86.1 million. Proceeds from sales and maturities of marketable securities were $1,194.9 million, partially offset by $691.8 million used for purchase of marketable securities. The net proceeds were used to acquire LitePoint.

Financing activities during 2011 used cash of $16.3 million, due to the repurchase of 2.6 million shares of common stock for $31.2 million at an average price of $11.84 per share and $2.5 million for payments on long-term debt, partially offset by $17.4 million from the issuance of common stock under stock option and stock purchase plans.

In 2010, changes in operating assets and liabilities, net of businesses sold and acquired, provided cash of $52.7 million. This was due to a $38.2 million increase in operating assets and a $90.9 million increase in operating liabilities. The increase in operating assets was due to an increase in accounts receivable of $50.4 million due to higher sales volume, partially offset by a $3.7 million decrease in inventories, and a decrease in other current assets of $8.5 million. The increase in operating liabilities was due to a $57.7 million increase in customer advance payments due primarily to an advanced payment received from one of our Semiconductor Test customers, a $44.5 million increase in accrued employee compensation due to higher variable compensation, a $15.0 million increase in accounts payable, a $15.0 million increase in deferred revenue, an $8.5 million increase in accrued income taxes, and a $2.7 million increase in other accrued liabilities, partially offset by $52.5 million of retirement plan contributions.

Investing activities during 2010 used cash of $627.7 million, due to $870.8 million used for purchases of marketable securities and $76.0 million used for purchases of property, plant and equipment, partially offset by proceeds from sales and maturities of marketable securities that provided cash of $318.1 million, and proceeds from life insurance that provided cash of $1.1 million.

Financing activities during 2010 provided cash of $42.4 million due to $44.7 million from the issuance of common stock under stock option and stock purchase plans which was partially offset by $2.3 million of cash used for payments on long-term debt related to the Japan loan.

In 2009, changes in operating assets and liabilities, net of businesses sold and acquired, provided cash of $78.9 million. This was due to a decrease in operating assets of $42.7 million and an increase in operating liabilities of $36.2 million. The decrease in operating assets consisted mainly of a decrease in inventory of $63.2 million partially offset by an increase of $19.3 million in accounts receivable due to higher sales volume. The increase in operating liabilities consisted of an increase in advanced customer payments, accounts payable, deferred revenue and other accrued expenses of $51.5 million partially offset by retirement plan contributions of $15.3 million. The $43.3 million increase in deferred revenue and customer advances in 2009 is due to an advanced payment of approximately $68.2 million received from one of our Semiconductor Test customers. The customer received an incremental discount and also wanted to secure its position in our manufacturing slot plan. This increase in customer advances was partially offset by a $24.9 million decrease in deferred revenue.

Investing activities in 2009 used cash of $93.3 million due to investments in property, plant and equipment of $41.3 million, payment of transaction fees related to the Eagle Test acquisition of $3.7 million, and purchases of marketable securities of $90.4 million, partially offset by sales and maturities of marketable securities that provided cash of $41.0 million, and proceeds from life insurance policies that provided cash of $1.1 million.

During 2009, financing activities provided cash of $66.1 million due to approximately $163.0 million of net proceeds from the issuance of the senior convertible notes, $10.0 million of long-term debt proceeds from a loan in Japan, and $15.7 million from the issuance of common stock under stock option and stock purchase plans. These increases were partially offset by $122.5 million of cash used for the repayment of our revolving credit facility and $1.1 million of cash used for principal payment on long-term debt.

On April 6, 2009, we completed a registered public offering of $190.0 million aggregate principal amount convertible senior notes (“Notes”) and settled the related convertible bond hedge and warrant transaction and received approximately $163.0 million as a result of these financing transactions. The Notes bear interest at a rate of 4.50% per annum, payable semi- annually in arrears on March 15 and September 15 of each year. The first interest payment was on September 15, 2009. The Notes will mature on March 15, 2014, unless earlier repurchased by us or converted. The Notes may be converted, under certain circumstances and during certain periods, at an initial conversion rate of approximately 182.65 shares of our common stock per $1,000 principal amount of Notes, which is equivalent to an initial conversion price of approximately $5.48. The convertible note hedge and warrant transaction will generally have the effect of increasing the conversion price of the Notes to approximately $7.67 per share of our common stock, representing a 75% conversion premium based upon the closing price of our common stock on March 31, 2009. We may not redeem the Notes prior to their maturity. Holders of the Notes may require us to purchase in cash all or a portion of their Notes at a price equal to 100% of the principal amount, plus accrued and unpaid interest, upon the occurrence of certain fundamental changes involving the Company.

We believe our cash, cash equivalents and marketable securities balance will be sufficient to meet working capital and expenditure needs for at least the next twelve months. We do not have significant cash outside the U.S. that if repatriated would incur additional taxes. In addition, the amount of cash, cash equivalents and marketable securities in the U.S. and our operations in the U.S. provide sufficient liquidity to fund our business activities in the U.S. Inflation has not had a significant long-term impact on earnings.

Retirement Plans

ASC 715-20, “Compensation – Retirement Benefits – Defined Benefit Plans” 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 ASC 715-20. 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 (“U.S. Plan”), certain qualified plans for non-U.S. subsidiaries, and a U.S. Supplemental Executive Defined Benefit Plan, was approximately $15.0 million for the year ended December 31, 2011. The largest portion of our 2011 pension expense was $7.0 million for our U.S. Plan. Pension expense is calculated based upon a number of actuarial assumptions, a significant input to the actuarial models that measure pension benefit obligations. Discount rate and expected return on assets are two assumptions which are important elements of pension plan expense and asset/liability measurement. We evaluate these critical assumptions at least annually on a plan and country specific basis. We evaluate other assumptions related to 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 U.S. Plan assets assumption, we evaluated input from our investment managers and pension consultants, including their review of asset class return expectations. Based on this review, we believe that 5.5% was an appropriate rate to use for 2011. We will continue to evaluate the expected return on plan assets at least annually, and will adjust the rate as necessary. The December 31, 2011 asset allocation for our U.S. Plan is 87% invested in fixed income securities, 12% invested in equity securities, and 1% invested in other

securities. Our investment managers regularly review the actual asset allocation and periodically rebalance the portfolio to ensure alignment with our targeted allocations.

We base our determination of pension expense 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, 2011, under the U.S. Plan, we had cumulative gains of approximately $23.3 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. Plan is based on the Citigroup Pension Index adjusted for the U.S. Plan’s expected cash flows and was 4.2% at December 31, 2011, down from 5.3% at December 31, 2010. We estimate that in 2012 we will recognize approximately $12.4 million of pension expense for the U.S. Plan. The U.S. Plan related pension expense estimate for 2012 is based on a 4.2% discount rate, and 5.0% return on U.S. Plan assets. Future pension expense 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, 2011, we had unrecognized pension losses and prior service costs of $134.1 million, of which $117.7 million is for the U.S. Plan.

We performed a sensitivity analysis, which expresses the potential U.S. Plan expense for the year ending December 31, 2012, that would result from changes to either the discount rate or the expected return on plan assets.

5.0%		13.8		12.4		11.0

The assets of the U.S. Plan consist primarily of fixed income and equity securities. The value of our U.S. Plan assets has increased from $275.7 million at December 31, 2010 to $319.1 million at December 31, 2011. Our funding policy is to make contributions to our pension plans in accordance with local laws and to the extent that such contributions are tax deductible. During 2011, we made a contribution of $1.7 million to the U.S. Supplemental Executive Defined Benefit Pension Plan and $8.5 million contribution to certain qualified plans for non-U.S. subsidiaries. We expect to contribute approximately $1.8 million to the U.S. Supplemental Executive Defined Benefit Pension Plan in 2012. Contributions that will be made in 2012 to certain qualified plans for non-U.S. subsidiaries are based on local statutory requirements and will be approximately $1.7 million. We do not expect to make any contributions to the U.S. Plan in 2012.

Equity Compensation Plans

In addition to our 1996 Employee Stock Purchase Plan discussed in Note N: “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 replaced 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.

At our annual meeting of stockholders held May 28, 2009, our stockholders approved an amendment to the 2006 Equity Plan to increase the number of shares issuable thereunder by 10.0 million, for an aggregate of

22.0 million shares issuable thereunder, and our stockholders also approved an amendment to our 1996 Employee Stock Purchase Plan to increase the number of shares issuable thereunder by 5.0 million, for an aggregate of 25.4 million shares issuable thereunder.

The following table presents information about these plans as of December 31, 2011 (share numbers in thousands):

In connection with the acquisition of Nextest (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, 2011, there were outstanding options exercisable for an aggregate of 1,036,584 shares of our common stock pursuant to the Nextest Plans, with a weighted average exercise price of $3.05 per share. As of December 31, 2011, there were outstanding restricted stock units covering an aggregate of 29,230 shares of our common stock, none of which are included in the calculation of the weighted average exercise price.

(5)

In connection with the acquisition of Eagle Test (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, 2011, there were outstanding options exercisable for an aggregate of 257,879 shares of our common stock pursuant to the Eagle Plans, with a weighted average exercise price of $3.65 per share.

(6)

In connection with the acquisition of LitePoint Corporation (the “LitePoint Acquisition”), we assumed the options granted under the LitePoint Corporation 2002 Stock Plan (the “LitePoint Plan”). Upon the consummation of the LitePoint Acquisition, these options were converted automatically into options to purchase an aggregate of 2,828,344 shares of our common stock. No additional awards will be granted under the LitePoint Plan. As of December 31, 2011, there were outstanding options exercisable for an aggregate of 2,771,821 shares of our common stock pursuant to the LitePoint Plan, with a weighted average exercise price of $2.71 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, 2011 was 12,160,945 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.

As of December 31, 2011, total unrecognized compensation expense related to non-vested awards and options totaled $60.3 million, and is expected to be recognized over a weighted average period of 2.6 years.

Recently Issued Accounting Pronouncements

In May 2011, the FASB issued ASU No. 2011-04, “Fair Value Measurement.” This ASU clarifies the concepts related to highest and best use and valuation premise, blockage factors and other premiums and discounts, the fair value measurement of financial instruments held in a portfolio and of those instruments classified as a component of shareowners’ equity. The guidance includes enhanced disclosure requirements about recurring Level 3 fair value measurements, the use of nonfinancial assets, and the level in the fair value hierarchy of assets and liabilities not recorded at fair value. The provisions of this ASU are effective prospectively for interim and annual periods beginning on or after December 15, 2011. Early application is prohibited. This ASU requires changes in presentation only and we do not expect it will have a material impact on its consolidated financial statements.

In June 2011, the FASB issued ASU No. 2011-05, “Comprehensive Income.” This ASU intends to enhance comparability and transparency of other comprehensive income components. The guidance provides an option to present total comprehensive income, the components of net income and the components of other comprehensive income in a single continuous statement or two separate but consecutive statements. This ASU eliminates the option to present other comprehensive income components as part of the statement of changes in shareowners’ equity. The provisions of this ASU will be applied retrospectively for interim and annual periods beginning after December 15, 2011. Early application is permitted. This ASU requires changes in presentation only and we do not expect it will have a material impact on its consolidated financial statements.

In September 2011, the FASB issued ASU No. 2011-08, “Intangibles-Goodwill and Other (Topic 350): Testing Goodwill for Impairment.” This new guidance is intended to simplify goodwill impairment testing by allowing companies to first assess qualitative factors to determine if it is more likely than not that goodwill might be impaired and whether it is necessary to perform the current two-step goodwill impairment test. This new guidance is effective for goodwill impairment tests performed in interim and annual periods for fiscal years beginning after December 15, 2011. Early adoption is permitted and we adopted the standard in the fourth quarter of 2011. The adoption did not have a material 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. Our fixed income available-for-sale marketable securities have a minimum rating of AA by one or more of the major credit rating agencies. 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 our 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 Euro, British Pound, Japanese Yen and the Taiwan Dollar. These foreign currency forward contracts have maturities of approximately one month. 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. 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, 2011, 2010 and 2009, 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. The potential change in fair value from changes in interest rates is immaterial as of December 31, 2011 and 2010.

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 consolidated financial statements 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, 2011 and 2010, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2011 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, 2011, 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 Controls 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.

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 Management’s Annual Report on Internal Controls over Financial Reporting appearing under Item 9A, management has excluded LitePoint Corporation from its assessment of internal control over financial reporting as of December 31, 2011 because it was acquired by the Company in a purchase business combination on October 5, 2011. We have also excluded LitePoint Corporation from our audit of internal control over financial reporting. LitePoint Corporation is a wholly-owned subsidiary whose total assets and total revenues represent 3% and 2%, respectively, of the related consolidated financial statement amounts as of and for the year ended December 31, 2011.

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,

•

wireless test (“Wireless Test”) systems.

B. ACCOUNTING POLICIES

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.

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, deferred tax assets, 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

In October 2009, the FASB amended the accounting standards for revenue recognition to remove tangible products containing non-software and software components that function together to deliver the product’s essential functionality from the scope of industry-specific software revenue recognition guidance. In October 2009, the FASB also amended the accounting standards for arrangements with multiple deliverables. Teradyne elected to early adopt this accounting guidance at the beginning of its first quarter of 2010 on a prospective basis. Adoption had no material impact on its financial position or results of operations in 2011 or 2010.

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 its 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 has non-software and software components that function together to deliver the equipment’s essential functionality. 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. Teradyne also defers the portion of the sales price that is not due until acceptance, which represents deferred profit.

For multiple element arrangements, Teradyne allocates revenue to all deliverables based on their relative selling prices. In such circumstances, a hierarchy is used to determine the selling price for allocating revenue to deliverables as follows: (i) vendor-specific objective evidence of selling price (“VSOE”), (ii) third-party evidence of selling price (“TPE”), and (iii) best estimate of the selling price (“BESP”). For a delivered item to be considered a separate unit, the delivered item must have value to the customer on a standalone basis and the delivery or performance of the undelivered item must be considered probable and substantially in Teradyne’s control.

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 days of product shipment and is completed within one to two days thereafter. Training services are optional and do not affect the customers’ ability to use the product. Teradyne defers revenue for the selling price of installation and training. Extended warranties constitute warranty obligations beyond one year and Teradyne defers revenue in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 605-20, “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, revenue is recognized in accordance with ASC 985-605, “Software Revenue Recognition.” Teradyne recognizes revenue when there is persuasive evidence of an arrangement, delivery has occurred, the sales price is fixed or determinable and collectability is probable. In instances where an arrangement contains multiple elements, revenue related to the undelivered elements is deferred 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 ASC 605-35, “Revenue Recognition Construction-Type and 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, 2011 and 2010, Teradyne had $1.1 million and $0.1 million, respectively, in unbilled amounts on long-term contracts included in accounts receivable. These amounts will be billed on a milestone basis in accordance with contractual terms.

As of December 31, 2011 and 2010, deferred revenue and customer advances consisted of the following and are included in the short and long-term deferred revenue and customer advances:


	2011		2010
	(in thousands)

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.

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.

Investments

Teradyne accounts for its investments in debt and equity securities in accordance with the provisions of ASC 320-10, “Investments—Debt and Equity Securities.” ASC 320-10 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;

•

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 defined in ASC 820-10 “Fair Value Measurements and Disclosures”, 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 years ended December 31, 2011, 2010 and 2009. ASC 820-10 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 ASC 820-10, Teradyne measures its debt and equity investments at fair value. Teradyne’s debt and equity investments are primarily classified within Level 2 with the exception of Teradyne’s investments in auction rate securities and contingent consideration, which were classified within Level 3.

Teradyne’s investments in auction rate securities were classified within Level 3 because there were no active markets for the auction rate securities and therefore Teradyne was unable to obtain independent valuations from market sources. The valuation technique used under Level 3 consisted of a discounted cash flow analysis which included 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. Teradyne determines the fair value of acquisition-related contingent consideration based on assessment of the probability that it would be required to make such payment.

Goodwill, Intangible and Long-Lived Assets

Teradyne accounts for goodwill and intangible assets in accordance with ASC 350-10, “Intangibles- Goodwill and Other.” 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. In September 2011, the FASB issued new guidance which provides an entity with the option to perform a qualitative assessment to determine whether it is more-likely-than-not that the fair value of a reporting unit is less than its carrying amount. If an entity determines this is the case, it is required to perform the two-step goodwill impairment test to identify potential goodwill impairment and measure the amount of goodwill impairment loss to be recognized. If an entity determines that this is more-likely-than-not that the fair value of the reporting unit is greater than its carrying amounts, the two-step goodwill impairment test is not required. This new guidance is effective for fiscal years beginning after December 15, 2011 with early adoption permitted. Teradyne adopted this guidance as of the fourth quarter of 2011.

Applying this new accounting guidance, Teradyne performed a qualitative assessment of its reporting unit and determined that is was not more-likely-than-not that the fair value of its reporting unit was less than its carrying amount.

In accordance with ASC 360-10, “Impairment or Disposal of Long-Lived Assets,” 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.

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, 2011, 2010 and 2009 was $7.8 million, $12.2 million and $14.5 million, respectively.

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.

Stock Compensation Plans and Employee Stock Purchase Plan

Equity Plans and Employee Stock Purchase Plan

Stock-based compensation expense is based on the grant-date fair value estimated in accordance with the provisions of ASC 718-10 “Compensation—Stock Compensation.” As required by ASC 718-10, Teradyne has made an estimate of expected forfeitures and is recognizing compensation costs only for those stock-based compensation awards expected to vest.

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.

Restricted stock unit awards granted to employees 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. A portion of restricted stock unit awards granted to executive officers is subject to time-based vesting and a portion of the 2011 and 2010 awards are 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 subject to time-based vesting, 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 may purchase shares of common stock through regular payroll deductions of up to 10% of their eligible compensation, to a maximum of shares with a fair market value of $25,000 per calendar year, not to exceed 6,000 shares. 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 the purchase period. There are two six-month purchase periods in each fiscal year.

The effect to income (loss) from continuing operations for recording stock-based compensation for the years ended December 31 was as follows:


	2011		2010		2009
	(in thousands)
Cost of revenue	$	7,097	$	6,536	$	4,138
Engineering and development		10,001		9,209		7,648
Selling and administrative		15,239		14,032		12,568

Stock-based compensation		32,337		29,777		24,354
Income tax benefit		—		—		(1,049	)

Total stock-based compensation expense after income taxes	$	32,337	$	29,777	$	23,305

Valuation Assumptions

The total number of stock options granted in 2011, 2010 and 2009 were 0.1 million, 0.3 million and 1.1 million, respectively, at the weighted average grant date fair value of $6.74, $4.10 and $1.97, respectively. The fair value of the stock options at grant date was estimated using the Black-Scholes option-pricing model with the following assumptions:


	2011			2010			2009
Expected life (years)		4.00			4.75			4.75
Interest rate		1.5	%		2.4	%		1.6	%
Volatility-historical		52.1	%		48.8	%		44.9	%
Dividend yield		0.0	%		0.0	%		0.0	%

Teradyne determined the stock option’s expected life based upon historical exercise data for executive officers, the age of executives and the terms of the stock option award. Volatility was determined using historical volatility for a period equal to the expected life. The interest rate was determined using the U.S. Treasury yield curve in effect at the time of grant.

The weighted-average fair value of employee stock purchase rights granted pursuant to the ESPP in the first and last six months of 2011 was $3.66 and $4.01, respectively, the first and last six months of 2010 was $3.05 and $2.77, respectively, and the first and last six months of 2009 was $1.66 and $2.49, respectively. The fair value of the employees’ purchase rights was estimated using the Black-Scholes option-pricing model with the following assumptions:


	2011			2010			2009
Expected life (years)		0.5			0.5			0.5
Interest rate		0.1	%		0.2	%		0.3	%
Volatility-historical		41.0	%		48.0	%		73.6	%
Dividend yield		0.0	%		0.0	%		0.0	%

As of December 31, 2011, there were 4.0 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 first utilizes non-equity related tax attributes, such as net operating losses and credit carryforwards and then equity-related tax attributes.

Advertising Costs

Teradyne expenses all advertising costs as incurred. Advertising costs were $1.0 million, $0.6 million and $0.7 million in 2011, 2010 and 2009, respectively.

Translation of Non-U.S. Currencies

The functional currency for all non-U.S. subsidiaries is the U.S. dollar. 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 and were a gain of $0.9 million, a gain of $2.5 million and a loss of $1.3 million, respectively, for the years ended December 31, 2011, 2010 and 2009. These amounts do not reflect the corresponding gain (loss) from foreign exchange contracts. See Note F: “Financial Instruments” regarding foreign exchange contracts. Revenue and expense amounts are translated using an average of exchange rates in effect during the period.

Net Income (Loss) per Common Share

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

Prior to the fourth quarter of 2010, net income for diluted net income (loss) per share includes an impact of convertible notes that represents interest expense that would have not been recorded if the notes converted at the beginning of the period. Dilutive potential common shares include incremental shares from assumed conversion of the convertible notes and the convertible notes hedge warrant shares. Incremental shares from assumed conversion of the convertible notes are calculated using the difference between the average Teradyne stock price for the period and the conversion price of $5.48, multiplied by the 34.7 million shares that will be issued upon conversion. The result of this calculation, representing total intrinsic value of the convertible debt, is divided by the average Teradyne stock price for the period. Convertible notes hedge warrant shares are calculated using the difference between the average Teradyne stock price for the period and the warrant price of $7.67, multiplied by the 34.7 million shares that will be issued upon conversion. The result of this calculation, representing total intrinsic value of the warrant, is divided by the average Teradyne stock price for the period. Teradyne’s call option for 34.7 million shares at an exercise price of $5.48 is not used in the GAAP earnings per share calculation as its effect would be anti-dilutive.

With respect to the Teradyne’s convertible debt, Teradyne intends to settle its conversion spread (i.e., the intrinsic value of the embedded option feature contained in the convertible debt) in shares. Teradyne accounts for its conversion spread using the treasury stock method. In the fourth quarter of 2010, Teradyne determined that it had the ability and intent to settle the principal amount of the convertible debt in cash; accordingly as of the fourth quarter of 2010, the principal amount has been excluded from the determination of diluted earnings per share.

Comprehensive Income (Loss)

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

C. RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

In May 2011, the FASB issued ASU No. 2011-04, “Fair Value Measurement.” This ASU clarifies the concepts related to highest and best use and valuation premise, blockage factors and other premiums and

discounts, the fair value measurement of financial instruments held in a portfolio and of those instruments classified as a component of shareowners’ equity. The guidance includes enhanced disclosure requirements about recurring Level 3 fair value measurements, the use of nonfinancial assets, and the level in the fair value hierarchy of assets and liabilities not recorded at fair value. The provisions of this ASU are effective prospectively for interim and annual periods beginning on or after December 15, 2011. Early application is prohibited. This ASU requires changes in presentation only and Teradyne does not expect it will have a material impact on its consolidated financial statements.

In June 2011, the FASB issued ASU No. 2011-05, “Comprehensive Income.” This ASU intends to enhance comparability and transparency of other comprehensive income components. The guidance provides an option to present total comprehensive income, the components of net income and the components of other comprehensive income in a single continuous statement or two separate but consecutive statements. This ASU eliminates the option to present other comprehensive income components as part of the statement of changes in shareowners’ equity. The provisions of this ASU will be applied retrospectively for interim and annual periods beginning after December 15, 2011. Early application is permitted. This ASU requires changes in presentation only and Teradyne does not expect it will have a material impact on its consolidated financial statements.

In September 2011, the FASB issued ASU No. 2011-08, “Intangibles-Goodwill and Other (Topic 350): Testing Goodwill for Impairment.” This new guidance is intended to simplify goodwill impairment testing by allowing companies to first assess qualitative factors to determine if it is more likely than not that goodwill might be impaired and whether it is necessary to perform the current two-step goodwill impairment test. This new guidance is effective for goodwill impairment tests performed in interim and annual periods for fiscal years beginning after December 15, 2011. Early adoption is permitted and Teradyne adopted the standard in the fourth quarter of 2011. The adoption did not have a material impact on Teradyne’s financial position or results of operations.

D. Discontinued Operations

On March 21, 2011, Teradyne completed the sale of its Diagnostic Solutions business unit, which was included in the Systems Test Group segment, to SPX Corporation for $40.2 million in cash. Teradyne sold this business as its growth potential as a stand-alone business within Teradyne was significantly less than if it was part of a larger automotive supplier. The financial information for Diagnostic Solutions has been reclassified to discontinued operations for all periods presented. Net revenues and income from discontinued operations for the years ended December 31, 2011, 2010 and 2009 were as follows:


	2011		2010		2009
	(in thousands)
Net revenues	$	9,086	$	42,488	$	41,982

Income from discontinued operation before income taxes	$	1,278	$	5,406	$	1,247
Gain from disposal of discontinued operation before income taxes		28,949		—		—
Income tax provision (benefit)		4,311		278		(279	)

Income from discontinued operations	$	25,916	$	5,128	$	1,526

E. ACQUISITIONS

Business

LitePoint Corporation

On October 5, 2011, Teradyne completed its acquisition of LitePoint Corporation (“LitePoint”) located in Sunnyvale, California. The total purchase price of $646.0 million consisted of $572.7 million of cash paid to acquire the outstanding common and preferred stock of LitePoint, $68.9 million in fair value of contingent consideration payable upon achievement of certain revenue targets through 2012 (the estimated undiscounted

range of outcomes for the contingent consideration is $62.0 million to $74.0 million) and $4.5 million in fair value of assumed vested stock options, which were converted into stock options to purchase Teradyne’s common stock. The fair value of stock options was estimated using the following weighted average assumptions:


Expected life (years)	6.2
Expected volatility	49.1	%
Risk-free interest rate	1.3	%
Dividend yield	0.0	%

The liability of $68.9 million arising from the contingent consideration is recorded as of December 31, 2011 and there has been no change to the acquisition date amount recognized, nor any change in the range of outcomes or assumptions used to develop the fair value. Teradyne expects the majority of this liability to be paid over the next twelve months.

LitePoint designs, develops, and supports advanced wireless test solutions for the development and manufacturing of wireless devices, including smart phones, tablets, notebooks/laptops, personal computer peripherals, and other Wi-Fi enabled devices. LitePoint’s IQ product line consists of cellular and connectivity test solutions used by developers and manufacturers of wireless devices and consumer electronics. LitePoint is Teradyne’s Wireless Test operating and reportable segment.

The LitePoint 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 LitePoint net tangible and identifiable intangible assets was based on their estimated fair values as of the acquisition date. The purchase price allocation is preliminary pending the final determination of the fair value of certain acquired assets and assumed liabilities. The excess of the purchase price over the identifiable intangible and net tangible assets in the amount of $352.8 million was allocated to goodwill, which is not deductible for tax purposes. The purchase price allocation below reflects this adjustment. The following represents the allocation of the purchase price:


	Purchase Price Allocation
	(in thousands)
Goodwill	$	352,778
Other intangible assets		310,500
Tangible assets acquired and liabilities assumed:
Cash, cash equivalents and short term marketable securities		61,250
Other current assets		72,109
Non-current assets		5,838
Accounts payable and current liabilities		(37,177	)
Long-term deferred tax liabilities		(115,463	)
Other long-term liabilities		(3,788	)

Total purchase price	$	646,047

Teradyne estimated the fair value of other intangible assets using the income and cost approach. Acquired other intangible assets are 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
	(in thousands)		(in years)
Developed technology	$	237,100		6.4
Customer relationships		53,700		7.0
Tradenames		19,000		7.0
Customer backlog		700		0.3

Total intangible assets	$	310,500		6.5

For the period from October 5, 2011 to December 31, 2011, LitePoint contributed $28.4 million of revenues and had a $(20.6) million loss from continuing operations before taxes.

The following unaudited pro forma information gives effect to the acquisition of LitePoint as if the acquisition occurred on January 1, 2010. The unaudited pro forma results are not necessarily indicative of what actually would have occurred had the acquisitions been in effect for the periods presented:


	For the Year Ended
	December 31, 2011		December 31, 2010
	(in thousands, except per share amounts)
Revenue	$	1,527,044	$	1,652,153
Income from continuing operations	$	329,461	$	304,459
Net income	$	355,377	$	309,882
Income from continuing operations per common share:
Basic	$	1.78	$	1.69

Diluted	$	1.44	$	1.40

Net income per common share:
Basic	$	1.92	$	1.72

Diluted	$	1.55	$	1.42

The pro forma results above include non recurring expenses related to acquired inventory fair value adjustment of $18.3 million and $13.3 million of transaction fees incurred by both, Teradyne & LitePoint.

During the year ended December 31, 2011, Teradyne recorded $4.6 million of charges related to acquisition costs. These charges are included in restructuring and other.

F. 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.

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 or trading at December 31, 2011 or 2010. At December 31, 2011 and 2010, Teradyne’s investments in equity and debt mutual funds, commercial paper, corporate debt securities and U.S. Treasury and government agency securities were classified as available-for-sale securities. Securities classified as available-for-sale 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 year ended December 31, 2009, Teradyne recorded realized losses of $2.1 million on the sale of its marketable securities. There were no realized losses recorded in 2011 and 2010. Unrealized gains and losses are included in accumulated other comprehensive income (loss). The cost of securities sold is based on the specific identification method.

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. The ARS portfolio was repurchased by UBS in 2010 and Teradyne no longer owns any ARS securities. During 2009, Teradyne recorded a net gain of $0.7 million in interest income in its consolidated statement of operations for the changes in the ARS fair value. During 2009, Teradyne recorded a $0.5 million loss in interest expense for a decrease in the fair value of the UBS Put, which was subsequently exercised in June 2010.

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, 2011 and 2010.
