A. The Company

•

•

wireless test (“Wireless Test”) systems.

B. Accounting Policies

Basis of Presentation

The condensed consolidated interim financial statements include the accounts of Teradyne and its subsidiaries. All significant intercompany balances and transactions have been eliminated. These interim financial statements are unaudited and reflect all normal recurring adjustments that are, in the opinion of management, necessary for the fair presentation of such interim financial statements. Certain prior year’s amounts were reclassified to conform to the current year presentation. The December 31, 2011 condensed consolidated balance sheet data was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States of America.

The accompanying financial information should be read in conjunction with the consolidated financial statements and notes thereto contained in Teradyne’s Annual Report on Form 10-K, filed with the SEC on February 29, 2012 for the year ended December 31, 2011.

Preparation of Financial Statements and Use of Estimates

The preparation of consolidated financial statements requires management to make estimates and judgments that affect the amounts reported in the financial statements. Actual results may differ significantly from these estimates.

C. Change in Accounting Principle

Effective January 1, 2012, Teradyne changed the method of recognizing actuarial gains and losses for its defined benefit pension plans and postretirement benefit plan and calculating the expected return on plan assets for its defined benefit pension plans. Historically, Teradyne recognized net actuarial gains and losses in accumulated other comprehensive income within shareholders’ equity on the consolidated balance sheets on an annual basis and amortized them into operating results over the average remaining years of service of the plan participants, to the extent such gains and losses were outside of a corridor. In addition, Teradyne, historically, calculated the expected return on plan assets using a calculated market-related value of plan assets. Teradyne has elected to immediately recognize net actuarial gains and losses and the change in the fair value of the plan assets in its operating results in the year in which they occur or upon any interim remeasurement of the plans. Teradyne has also elected to calculate the expected return on plan assets using the fair value of the plan assets.

While the previous method of recognizing pension and other postretirement benefit expense was considered acceptable, Teradyne believes that this new method is preferable as it eliminates the delay in recognizing gains and losses in its operating results and it will improve the transparency by faster recognition of the effects of

economic and interest rate trends on plan obligations and investments. These actuarial gains and losses are generally measured annually as of December 31 and, accordingly, will be recorded during the fourth quarter of each year or upon any interim remeasurement of the plans. In accordance with Financial Accounting Standards Board Accounting Standards Codification Topic 250, Accounting Changes and Error Corrections, all prior periods presented in this Quarterly Report on Form 10-Q have been adjusted to apply the new accounting method retrospectively. This accounting change did not impact the financial position of the reportable segments.

Had these changes not been made, net income for the three months ended April 1, 2012 would have been $29.7 million compared to the $33.6 million actually recorded. Diluted earnings per share would have been $0.13 compared to $0.15.

The effects of the change in accounting principle on the condensed consolidated financial statements for 2011 are presented below. We have condensed the comparative financial statements for financial statement line items that were not affected by the change in accounting principle.

D. Recently Issued Accounting Pronouncements

In December 2011, the FASB issued ASU No. 2011-11, “Disclosures about Offsetting Assets and Liabilities.” This ASU is intended to enhance a financial statement user’s ability to understand the effects of netting arrangements on an entity’s financial statements, including financial instruments and derivative instruments that are either offset or subject to an enforceable master netting or similar arrangement. The scope of this ASU includes derivatives, sale and repurchase agreements and reverse sale and repurchase agreements, and securities borrowing and securities lending arrangements. This ASU includes enhanced disclosure requirements, including both gross and net information about instruments and transactions eligible for offset or subject to an agreement similar to a master netting arrangement. The provisions of this ASU will be applied retrospectively for interim and annual periods beginning on or after January 1, 2013. Teradyne is currently evaluating the impact of this new ASU.

E. 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 three months ended April 3, 2011 were as follows:


	April 3, 2011
	(in thousands)
Net revenues	$	9,086

Income from discontinued operations before income taxes	$	1,436
Gain from disposal of discontinued operations before income taxes		29,781
Income tax provision		4,311

Income from discontinued operations	$	26,906

F. Financial Instruments and Derivatives

Financial Instruments

Teradyne uses the market and income approach to value its financial instruments and there was no change in valuation techniques used by Teradyne during the three months ended April 1, 2012 and April 3, 2011. 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. ASC 820-10 requires that assets and liabilities are carried at fair value and are classified 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.

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.

During the three months ended April 1, 2012 and April 3, 2011, there were no significant transfers in and out of Level 1, Level 2 and Level 3.

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 April 1, 2012 and December 31, 2011.

Contingent consideration is measured at fair value and is based on significant inputs not observable in the market, which represents a Level 3 measurement within the fair value hierarchy. The valuation of contingent consideration uses assumptions and estimates to forecast a range of outcomes for the contingent consideration. Teradyne assesses these assumptions and estimates on a quarterly basis as additional data impacting the assumptions is obtained. Changes in the fair value of contingent consideration related to updated assumptions and estimates are recognized within the condensed consolidated statements of operations.

The following table provides quantitative information associated with the fair value measurement of the Teradyne’s Level 3 inputs:


Liability	Fair Value (Thousands)		Valuation Technique	Unobservable Inputs	Weighted Average
Contingent consideration	$	61,210	Income approach— discounted cash flow	Revenue earn-out—probability of low case (scenario) for calendar year 2012 revenue.		70	%
			Income approach— discounted cash flow	Revenue earn-out—probability of high case (scenario) for calendar year 2012 revenue.		30	%
				Discount rate for revenue earn-out		3.5	%
				Discount rate for cellular earn-out		3.5	%

The significant unobservable inputs used in the fair value measurement of contingent consideration are the probabilities of successful achievement of calendar year 2012 revenues, the quarterly period in which the revenues are expected to be achieved and a discount rate. Increases or decreases in any of the probabilities of success would result in a higher or lower fair value measurement. Increases or decreases in the period in which milestones will be achieved would result in a lower or higher fair value measurement, respectively.

The following table represents changes in the fair value of Level 3 contingent consideration:

Derivatives

Teradyne conducts business in a number of foreign countries, with certain transactions denominated in local currencies. The purpose of Teradyne’s foreign currency management is to minimize the effect of exchange rate fluctuations on certain foreign currency denominated net monetary assets. Teradyne does not use derivative financial instruments for trading or speculative purposes.

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

The notional amount of foreign exchange contracts hedging monetary assets and liabilities denominated in foreign currencies was $71.4 million and $85.4 million at April 1, 2012 and December 31, 2011, respectively.

The following table summarizes the fair value of derivative instruments at April 1, 2012 and December 31, 2011.

G. Debt

Loan Agreement

On March 31, 2009, Teradyne K.K., Teradyne’s wholly-owned subsidiary in Japan, entered into a loan agreement with a local bank in Japan to borrow approximately $10.0 million. The loan has a term of 5 years and a fixed interest rate of 0.81%. Approximately $6.0 million of the loan is collateralized by a real estate mortgage on Teradyne K.K.’s building and land in Kumamoto, Japan and approximately $4.0 million is unsecured. Teradyne, Inc. has guaranteed payment of the loan obligation. The loan is amortized over the term of the loan with semiannual principal payments of approximately $1.0 million payable on September 30 and March 30 each year. At April 1, 2012, approximately $2.4 million of the outstanding loan principal is included in current debt and approximately $2.4 million is classified as long-term debt.

Convertible Senior Notes

In April 2009, Teradyne issued 4.50% convertible senior notes (the “Notes”) at an aggregate principal amount of $190 million. The Notes will mature on March 15, 2014, unless earlier repurchased by Teradyne or converted. The Notes are senior unsecured obligations and rank equally with all of Teradyne’s existing and future senior debt and senior to any of Teradyne’s subordinated debt.

The Notes may be converted, under certain circumstances and during certain periods, at an initial conversion rate of approximately 182.65 shares of Teradyne’s common stock per $1,000 principal amount of Notes, which is equivalent to an initial conversion price of approximately $5.48, a 25% conversion premium based on the last reported sale price of $4.38 per share of Teradyne’s common stock on March 31, 2009. The conversion rate is subject to adjustment in certain circumstances.

During the three months ended April 1, 2012, the following circumstance that allows holders to convert their Notes at their option prior to December 15, 2013 occurred: the last reported sale price of Teradyne’s common stock for 20 or more trading days in a period of 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter exceeded 130% of the conversion price in effect on the last trading day of the immediately preceding calendar quarter. As of May 11, 2012, no holders have exercised their option to convert their Notes.

Concurrently with the offering of the Notes, Teradyne entered into a convertible note hedge transaction with a strike price equal to the initial conversion price of the Notes, or approximately $5.48. The convertible note hedge allows Teradyne to receive shares of its common stock and/or cash related to the excess conversion value that it would pay to the holders of the Notes upon conversion. The convertible note hedges will cover, subject to customary antidilution adjustments, approximately 34,703,196 shares of Teradyne’s common stock. Teradyne paid approximately $64.6 million for the convertible note hedges.

Separately, Teradyne entered into a warrant transaction with a strike price of approximately $7.67 per share, which was 75% higher than the closing price of Teradyne’s common stock on March 31, 2009. Teradyne received approximately $43.0 million for the warrants.

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 Teradyne’s common stock, representing a 75% conversion premium based upon the closing price of Teradyne’s common stock on March 31, 2009.

The Notes are classified as long-term debt in the balance sheet at April 1, 2012 and December 31, 2011. The tables below represent the components of Teradyne’s convertible senior notes:


	April 1, 2012		December 31, 2011
	(in thousands)
Debt principal	$	190,000	$	190,000
Unamortized debt discount		30,627		33,902

Amortization of the discount component and debt issue fees		3,479		3,061

Total interest expense on the convertible debt	$	5,640	$	5,270

As of April 1, 2012, the unamortized discount was $30.6 million, which will be amortized over approximately 2.0 years, and the carrying amount of the equity component was $63.4 million. As of April 1, 2012, the conversion rate was equal to the initial conversion price of approximately $5.48 per share and the if-converted value of the Notes was $586.1 million.

H. Deferred Revenue and Customer Advances

Deferred revenue and customer advances consist of the following and are included in short and long-term deferred revenue and customer advances.

I. Product Warranty

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


	For the Three Months Ended
	April 1, 2012			April 3, 2011

Balance at end of period	$	12,927		$	9,870

J. Stock-Based Compensation

Restricted stock unit awards granted to employees vest in equal installments over four years. A portion of the restricted stock unit awards granted to executive officers is subject to service-based vesting and a portion of the awards is subject to performance-based vesting. The percentage level of performance satisfied for performance-based grants is assessed on or near the anniversary of the grant date and, in turn, that percentage level determines the number of performance-based restricted stock units available for vesting over the vesting period; portions of the performance-based grants not available for vesting are forfeited. Service-based stock options vest in equal installments over four years, and have a term of seven years from the date of grant.

During the three months ended April 1, 2012, Teradyne granted 1.5 million of restricted stock unit awards to employees at a weighted average grant date fair value of $16.88 and 0.2 million of service-based stock options to executive officers at a weighted average grant date fair value of $6.85.

During the three months ended April 3, 2011, Teradyne granted 1.5 million of restricted stock unit awards to employees at a weighted average grant date fair value of $16.23 and 0.1 million of service-based stock options to executive officers at a weighted average grant date fair value of $6.74.

The fair value of stock options was estimated using the Black-Scholes option-pricing model with the following assumptions:


	For the Three Months Ended
	April 1, 2012			April 3, 2011
Expected life (years)		3.50			4.00
Interest rate		0.4	%		1.5	%
Volatility-historical		56.0	%		52.1	%
Dividend yield		0.0	%		0.0	%

Teradyne determined the stock options’ expected life based upon historical exercise data for executive officers, the age of the executive officers and the terms of the stock option grant. Volatility was determined using historical volatility for a period equal to the expected life. The risk-free 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 in the first three months of 2012 and 2011 was $4.09 and $3.66, respectively. The fair value of the employees’ purchase rights was estimated using the Black-Scholes option-pricing model with the following assumptions:


	For the Three Months Ended
	April 1, 2012			April 3, 2011
Expected life (years)		0.5			0.5
Interest rate		0.06	%		0.14	%

Incremental shares from assumed conversion of the convertible notes for the three months ended April 1, 2012 and April 3, 2011 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 would 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.

(2)

Convertible notes hedge warrant shares for the three months ended April 1, 2012 and April 3, 2011 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 would 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.

The computation of diluted net income per common share for the three months ended April 1, 2012 excludes the effect of the potential exercise of stock options to purchase approximately 0.3 million shares and restricted stock units of 1.0 million because the effect would have been anti-dilutive.

The computation of diluted net income per common share for the three months ended April 3, 2011 excludes the effect of the potential exercise of stock options to purchase approximately 1.6 million shares because the effect would have been 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.

M. Restructuring and Other, Net

Other

During the three months ended April 1, 2012, Teradyne recorded a $1.9 million fair value adjustment to decrease the LitePoint acquisition contingent consideration. As of April 1, 2012, the estimated undiscounted range of outcomes for the contingent consideration is $54.0 million to $66.0 million. The decrease in the range from December 31, 2011 is due to the $5.8 million contingent consideration payment during the three months ended April 1, 2012 and the $1.9 million fair value decrease.

Restructuring

In response to a downturn in the industry in 2008 and 2009, Teradyne initiated restructuring activities across all segments to reduce costs, principally through headcount reductions and facility consolidations. The remaining accrual for lease payments on vacated facilities of $1.7 million is reflected in the other accrued liabilities account and the long-term other accrued liabilities account and is expected to be paid over the lease terms, the latest of which expires in 2013. Teradyne expects to pay approximately $0.8 million against the lease accruals over the next twelve months. Teradyne’s future lease commitments are net of expected sublease income of $0.4 million as of April 1, 2012. The table below represents activity related to these actions.

N. Retirement Plans

Defined Benefit Pension Plans

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

Components of net periodic pension cost for all plans were as follows:


	For the Three Months Ended
	April 1, 2012			April 3, 2011
	(in thousands)
Service cost	$	722		$	769
Interest cost		4,083			4,327

Prior service cost		58			155

Total net periodic pension cost	$	776		$	1,338

In the three months ended April 1, 2012, Teradyne contributed $0.7 million, primarily to its foreign pension plans.

Post-Retirement Benefit Plans

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

Components of net periodic post-retirement cost were as follows:

O. Commitments and Contingencies

Purchase Commitments

As of April 1, 2012, Teradyne had entered into purchase commitments for certain components and materials. The purchase commitments aggregate to approximately $273.2 million, of which $272.8 million is for less than one year.

Legal Claims

Teradyne is subject to various legal proceedings and claims which have arisen in the ordinary course of business. In the opinion of management, the ultimate disposition of these matters will not have a material adverse effect on Teradyne’s results of operations, financial condition or cash flows.

P. Segment Information

Teradyne has three operating segments (Semiconductor Test, Systems Test Group and Wireless Test), which are its reportable segments. The Semiconductor Test segment includes operations related to the design, manufacturing and marketing of semiconductor test products and services. The Systems Test Group segment includes operations related to design, manufacturing and marketing of products and services for military/aerospace instrumentation test, storage test and circuit-board test. The Wireless Test segment includes operations related to design, manufacturing and marketing of wireless test products and services. Each operating segment has a segment manager who is directly accountable to and maintains regular contact with Teradyne’s chief operating decision maker (Teradyne’s chief executive officer) to discuss operating activities, financial results, forecasts, and plans for the segment.

Teradyne evaluates performance based on several factors, of which the primary financial measure is business segment income before income taxes. The accounting policies of the business segments are the same as those described in Note B “Accounting Policies” in Teradyne’s Annual Report on Form 10-K for the year ended December 31, 2011. Segment information is as follows:

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

Statements in this Quarterly Report on Form 10-Q 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. See also Part II, Item 1A of this Quarterly Report on Form 10-Q and Part I, Item 1A “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2011. 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,

•

wireless test (“Wireless Test”) systems.

We have a broad customer base which includes integrated device manufacturers (“IDMs”), outsourced semiconductor assembly and test providers (“OSATs”), wafer foundries, fabless companies that design, but contract with others for the manufacture of integrated circuits (“ICs”), developers of wireless devices and consumer electronics, manufacturers of circuit boards, automotive suppliers, wireless product manufacturers, storage device manufacturers, aerospace and military contractors as well as the United States Department of Defense.

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 businesses to expand further our addressable markets while tightly managing our costs.

We regularly face price competition in each of our businesses. 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.

Critical Accounting Policies and Estimates

We have identified the policies which are critical to understanding our business and our results of operations. There have been no significant changes during the three months ended April 1, 2012 to the items disclosed as our critical accounting policies and estimates in Management’s Discussion and Analysis of Financial Condition and Results of Operations in our Annual Report on Form 10-K for the fiscal year ended December 31, 2011.

Effective January 1, 2012, we changed the method of recognizing actuarial gains and losses for our defined benefit pension plans and postretirement benefit plan and calculating the expected return on plan assets for our defined benefit pension plans. Historically, we recognized net actuarial gains and losses in accumulated other comprehensive income within shareholders’ equity on our consolidated balance sheets on an annual basis and amortized them into operating results over the average remaining years of service of the plan participants, to the extent such gains and losses were outside of a corridor. In addition, we, historically, calculated the expected return on plan assets using a calculated market-related value of plan assets. We have elected to immediately recognize net actuarial gains and losses and the change in the fair value of the plan assets in our operating results in the year in which they occur or upon any interim remeasurement of the plans. We have also elected to calculate the expected return on plan assets using the fair value of the plan assets.

While the previous method of recognizing pension and other postretirement benefit expense was considered acceptable, we believe that this new method is preferable as it eliminates the delay in recognizing gains and losses in our operating results and it will improve the transparency by faster recognition of the effects of economic and interest rate trends on plan obligations and investments. These actuarial gains and losses are generally measured annually as of December 31 and, accordingly, will be recorded during the fourth quarter of each year or upon any interim remeasurement of the plans. In accordance with Financial Accounting Standards Board Accounting Standards Codification Topic 250, Accounting Changes and Error Corrections, all prior periods presented in this Quarterly Report on Form 10-Q have been adjusted to apply the new accounting method retrospectively. This accounting change did not impact the financial position of the reportable segments.

Book to Bill Ratio

Book to bill ratio is calculated as net bookings divided by net sales. Book to bill ratio by reportable segment was as follows:


	For the Three Months Ended
	April 1, 2012		April 3, 2011
Semiconductor Test		1.4		1.1
Systems Test Group		0.5		1.3
Wireless Test		1.3		—

Revenue

Net revenues by reportable segments were as follows:


	For the Three Months Ended				Dollar Change
	April 1, 2012		April 3, 2011		Dollar Change
	(in millions)
Semiconductor Test	$	267.6	$	319.3	$	(51.7	)

Wireless Test		31.3		—		31.3

	$	396.7	$	377.2	$	19.5

The decrease of $51.7 million or 16% in Semiconductor Test revenue was due to a decrease across all System-on-a-Chip and memory product sales revenue. The increase in Systems Test Group revenue of $39.9 million or 69% was primarily due to the increase in sales of Storage Test systems. The acquisition of LitePoint, which is our Wireless Test segment, completed in October of 2011, added $31.3 million of revenue in the three months ended April 1, 2012.

Our revenues by region as a percentage of total net revenue were as follows:

Gross Profit

Our gross profit was as follows:


	For the Three Months Ended						Dollar/Point Change
	April 1, 2012			April 3, 2011			Dollar/Point Change
	(in millions)
Gross Profit	$	190.9		$	192.9		$	(2.0	)
Percent of Total Revenue		48.1	%		51.1	%		(3.0	)

Gross profit as a percent of revenue decreased by 3.0 percentage points. This decrease was the result of a decrease of 5.5 points related to System-on-a-Chip product mix and higher Storage Test systems sales. This decrease was partially offset by an increase of 1.8 points due to the addition of LitePoint, and an increase of 0.7 points due to lower inventory provisions.

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 three months ended April 1, 2012, we recorded an inventory provision of $1.6 million included in cost of revenues, due to the downward revisions to previously forecasted demand levels. Of the $1.6 million of total excess and obsolete provisions recorded in the three months ended April 1, 2012, $0.9 million was related to Systems Test Group, and $0.5 million was related to Wireless Test, and $0.2 million was related to Semiconductor Test.

During the three months ended April 3, 2011, we recorded an inventory provision of $4.6 million included in cost of revenues, due to the downward revisions to previously forecasted demand levels. Of the $4.6 million of total excess and obsolete provisions recorded in the three months ended April 3, 2011, $4.4 million was related to Semiconductor Test and $0.2 million was related to Systems Test Group.

During the three months ended April 1, 2012 and April 3, 2011, we scrapped $4.1 million and $0.3 million of inventory, respectively. During the three months ended April 1, 2012 and April 3, 2011, we sold $1.3 million and $3.0 million, respectively, of previously written-down or written-off inventory. As of April 1, 2012, we had inventory related reserves for amounts which had been written-down or written-off totaling $120.7 million. We have no pre-determined timeline to scrap the remaining inventory.

Engineering and Development

Engineering and development expenses were as follows:


	For the Three Months Ended						Dollar Change
	April 1, 2012			April 3, 2011			Dollar Change
	(in millions)
Engineering and Development	$	60.1		$	47.1		$	13.0
Percent of Total Revenue		15.2	%		12.5	%

The increase of $13.0 million in engineering and development expenses is due primarily to additional costs of $8.6 million related to LitePoint which was acquired in October 2011 and increased spending on engineering projects.

Selling and Administrative

Selling and administrative expenses were as follows:


	For the Three Months Ended						Dollar Change
	April 1, 2012			April 3, 2011			Dollar Change
	(in millions)
Selling and Administrative	$	67.8		$	57.7		$	10.1
Percent of Total Revenue		17.1	%		15.3	%

The increase of $10.1 million in selling and administrative expenses is due primarily to additional costs of $10.7 million related to LitePoint.

Restructuring and Other, Net

Other

During the three months ended April 1, 2012, we recorded a $1.9 million fair value adjustment to decrease the LitePoint acquisition contingent consideration. As of April 1, 2012, the estimated undiscounted range of outcomes for the contingent consideration is $54.0 million to $66.0 million. The decrease in the range from December 31, 2011 is due to the $5.8 million contingent consideration payment during the three months ended April 1, 2012 and the $1.9 million fair value decrease.

Restructuring

In response to a downturn in the industry in 2008 and 2009, we initiated restructuring activities across all segments to reduce costs, principally through headcount reductions and facility consolidations. The remaining accrual for lease payments on vacated facilities of $1.7 million is reflected in the other accrued liabilities account and the long-term other accrued liabilities account and is expected to be paid over the lease terms, the latest of which expires in 2013. We expect to pay approximately $0.8 million against the lease accruals over the next twelve months. Our future lease commitments are net of expected sublease income of $0.4 million as of April 1, 2012. The table below represents activity related to these actions.

•

$0.6 million of severance charges related to headcount reductions of 5 people in Semiconductor Test.

Q2 2010 Actions:

•

$0.2 million related to a change in the estimated severance benefits related to headcount reductions in Semiconductor Test.

Q4 2010 Actions:

•

$0.1 million of severance charges related to headcount reductions in Semiconductor Test.

Pre-2011 Actions:

•

Interest and Other

Interest income decreased by $0.4 million, from the first quarter of 2011 to 2012, due to a decrease in marketable securities due to the LitePoint acquisition.

Income Taxes

For the three months ended April 1, 2012, we recorded a tax provision of $7.7 million from continuing operations, which consisted of foreign taxes and U.S. deferred tax provision. For the three months ended April 1, 2011, we recorded a tax provision of $5.5 million which consisted primarily of foreign taxes.

On a quarterly basis, we evaluate the realizability of our deferred tax assets by jurisdiction and assess the need for a valuation allowance. At April 1, 2012, we believe that we will ultimately realize the deferred tax assets recorded on our condensed consolidated balance sheet. However, should we believe that it is more likely than not that our deferred tax assets would not be realized, our tax provision would increase in the period in which we determined that the realizability was not likely. We consider the probability of future taxable income and our historical profitability, among other factors, in assessing the realizability of our deferred tax assets.

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 by $12.5 million in the three months ended April 1, 2012, to $742.1 million. Cash activity for the three months ended April 1, 2012 and April 3, 2011 was as follows:


	For the Three Months Ended
	April 1, 2012			April 3, 2011
	(in millions)

Income from continuing operations, adjusted for non-cash items	$	90.3		$	106.0

Total cash provided by financing activities		2.9			8.9

(Decrease) Increase in cash and cash equivalents	$	(40.3	)	$	22.5

In the three months ended April 1, 2012, changes in operating assets and liabilities used cash of $79.1 million. This was due to a $66.7 million increase in operating assets and a $12.4 million decrease in operating liabilities.

The increase in operating assets from December 31, 2011 was due to a $92.2 million increase in accounts receivable due to higher sales volume, partially offset by a $23.6 million decrease in inventories and a $1.9 million decrease in prepayments. The decrease in operating liabilities from December 31, 2011 was due to a $46.1 million decrease in accrued employee compensation due primarily to variable compensation payments, a $4.2 million decrease in customer advance payments due to shipments of systems prepaid by customers, $1.1 million of retirement plans contributions, partially offset by a $36.5 million increase in accounts payable due to increased sales volume, and a $2.5 million increase in deferred revenue.

Investing activities during the three months ended April 1, 2012 used cash of $54.4 million, due to $80.1 million used for purchases of marketable securities and $27.1 million used for capital expenditures, partially offset by $52.8 million of proceeds from sales and maturities of marketable securities.

Financing activities during the three months ended April 1, 2012 provided cash of $2.9 million, $9.9 million was from the issuance of common stock under stock option and stock purchase plans, partially offset by $5.8 million of cash used for payments related to LitePoint acquisition contingent consideration and $1.2 million of cash used for payments on long-term debt related to the Japan loan.

In the three months ended April 3, 2011, changes in operating assets and liabilities, net of businesses sold, used cash of $82.2 million. This was due to a $30.5 million increase in operating assets and a $51.7 million decrease in operating liabilities.

The increase in operating assets from December 31, 2010 was due to a $17.5 million increase in accounts receivable and a $10.7 million increase in inventories due to higher sales volume, and a $2.3 million increase in other current assets. The decrease in operating liabilities from December 31, 2010 was due to a $56.8 million

decrease in accrued employee compensation due primarily to variable compensation payments, a $27.1 million decrease in customer advance payments due to shipments of systems prepaid by customers in 2010 and $1.2 million of retirement plans contributions, partially offset by a $28.0 million increase in accounts payable due to increased sales volume, a $2.9 million increase in other accrued liabilities and a $2.5 million increase in deferred revenue.

Investing activities during the three months ended April 3, 2011 used cash of $45.0 million, due to $211.3 million used for purchases of marketable securities and $22.1 million used for capital expenditures, partially offset by proceeds from sales and maturities of marketable securities that provided cash of $188.4 million.

Investing activities of discontinued operations during the three months ended April 3, 2011, provided cash of $39.0 million. Included in this balance is the net proceeds received for the sale of our Diagnostic Solutions business unit to SPX Corporation on March 21, 2011.

Financing activities during the three months ended April 3, 2011 provided cash of $8.9 million, $10.1 million was from the issuance of common stock under stock option and stock purchase plans which was partially offset by $1.2 million of cash used for a payment on a long-term debt related to the Japan loan.

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.

Equity Compensation Plans

As discussed in Note N “Stock Based Compensation” in our 2011 Form 10-K, we have a 1996 Employee Stock Purchase Plan and a 2006 Equity and Cash Compensation Incentive Plan (the “2006 Equity Plan”).

The purpose of the 1996 Employee Stock Purchase Plan is to encourage stock ownership by all eligible employees of Teradyne. The purpose of the 2006 Equity Plan is to provide equity ownership and compensation opportunities in Teradyne to our employees, officers, directors, consultants and/or advisors. Both plans were approved by our shareholders.

Recently Issued Accounting Pronouncements

In December 2011, the FASB issued ASU No. 2011-11, “Disclosures about Offsetting Assets and Liabilities.” This ASU is intended to enhance a financial statement user’s ability to understand the effects of netting arrangements on an entity’s financial statements, including financial instruments and derivative instruments that are either offset or subject to an enforceable master netting or similar arrangement. The scope of this ASU includes derivatives, sale and repurchase agreements and reverse sale and repurchase agreements, and securities borrowing and securities lending arrangements. This ASU includes enhanced disclosure requirements, including both gross and net information about instruments and transactions eligible for offset or subject to an agreement similar to a master netting arrangement. The provisions of this ASU will be applied retrospectively for interim and annual periods beginning on or after January 1, 2013. We are currently evaluating the impact of this new ASU.

Item 3:

Quantitative and Qualitative Disclosures about Market Risk

For “Quantitative and Qualitative Disclosures about Market Risk” affecting Teradyne, see Item 7a. “Quantitative and Qualitative Disclosures about Market Risks,” in our Annual Report on Form 10-K filed with the SEC on February 29, 2012. There were no material changes in our exposure to market risk from those set forth in our Annual Report for the fiscal year ended December 31, 2011.

Item 4:

Controls and Procedures

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

During the period covered by this report, there have been no changes in our internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met.

PART II. OTHER INFORMATION

Risk Factors

You should carefully consider the factors discussed in Part I, “Item 1A: Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2011, which could materially affect our business, financial condition or future results.
