Teradyne, Inc. (“Teradyne”) is a leading global supplier of automation equipment for test and industrial applications. Teradyne designs, develops, manufactures and sells automatic test systems used to test semiconductors, wireless products, data storage and complex electronics systems in the consumer electronics, wireless, automotive, industrial, computing, communications, and aerospace and defense industries. Teradyne’s industrial automation products include collaborative robots used by global manufacturing and light industrial customers to improve quality, increase manufacturing efficiency and decrease manufacturing costs. Teradyne’s automatic test equipment and industrial automation products and services include:

On June 11, 2015, Teradyne acquired Universal Robots A/S (“Universal Robots”) for approximately $284 million of cash plus up to an additional $65 million of cash if certain performance targets are met extending through 2018. Universal Robots is the leading supplier of collaborative robots which are low-cost, easy-to-deploy and simple-to-program robots that work side by side with production workers to improve quality and increase manufacturing efficiency.

The consolidated interim financial statements include the accounts of Teradyne and its wholly-owned 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 amounts were reclassified to conform to the current year presentation. The December 31, ~~2014~~2015 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 U.S. Securities and Exchange Commission (“SEC”) on February ~~27, 2015,~~29, 2016, for the year ended December 31, ~~2014.~~2015.

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.

~~Teradyne recognizes revenue when there is persuasive evidence of an arrangement, title and risk of loss have passed, delivery has occurred or~~In January 2016, the ~~services have been rendered, the sales price is fixed or determinable and collection of the related receivable is reasonably assured. Title and risk of loss generally pass to Teradyne’s~~

customers upon shipment or at delivery destination point. In circumstances where either title or risk of loss pass upon destination, acceptance or cash payment, Teradyne defers revenue recognition until such events occur except when title transfer is tied to cash payment outside the United States. Outside the United States, Teradyne recognizes revenue upon shipment or at delivery destination point, even if Teradyne retains a form of title to products delivered to customers, provided the sole purpose is to enable Teradyne to recover the products in the event of customer payment default and the arrangement does not prohibit the customer’s use or resale of the product in the ordinary course of business.

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”) issued Accounting Standards Update (“ASU”) 2016-01,“Financial Instruments—Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities.”This ASU provides guidance for the recognition, measurement, presentation, and disclosure of financial instruments. The new pronouncement revises accounting related to equity investments and the presentation of certain fair value changes for financial liabilities measured at fair value. Among other things, it amends the presentation and disclosure requirements of equity securities that do not

result in consolidation and are not accounted for under the equity method. Changes in the fair value of these equity securities will be recognized directly in net income. This pronouncement is effective for fiscal years and interim periods within those years beginning after December 15, 2017. Teradyne is currently evaluating the impact of this ASU on its financial position and results of operations.

On March 31, 2016, the FASB issued ASU 2016-09,“Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting.” This ASU changes how companies account for certain aspects of share-based payment awards to employees, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as classification in the statement of cash flows. This pronouncement is effective for annual periods beginning after December 15, 2016. Early adoption is permitted. Teradyne is currently evaluating the impact of this ASU on its financial position and results of operations.

In February 2016, the FASB issued ASU 2016-02,“Leases (Topic 842).” The guidance in this ASU supersedes the lease recognition requirements in Accounting Standards Codification (“ASC”) ~~605-20,~~Topic 840,“~~Separately Priced Extended Warranty and Product Maintenance Contracts”~~ ~~and ASC 605-25,~~~~“Revenue Recognition Multiple-Element Arrangements.~~Leases.” ~~Service revenue is recognized over~~The new standard establishes a right-of-use (“ROU”) model that requires a lessee to record a ROU asset and a lease liability on the ~~contractual period or as services are performed.~~

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

~~The functional currency~~balance sheet for all ~~non-U.S. subsidiaries is~~leases with terms longer than twelve months. Leases will be classified as either finance or operating, with classification affecting the U.S. dollar, except for the Industrial Automation segment for which the local currency is its functional currency. All foreign currency denominated monetary assets and liabilities are remeasured on a monthly basis into the functional currency using exchange rates in effect at the endpattern of the period. All foreign currency denominated non-monetary assets and liabilities are remeasured into the functional currency using historical exchange rates. Net foreign exchange gains and losses resulting from remeasurement are included in other (income) expense net. For Industrial Automation, assets and liabilities are translated into U.S. dollars using exchange rates in effect at the end of the period. Revenue and expense amounts are translated using an average of exchange rates in effect during the period. Translation adjustments are recorded within accumulated other comprehensive income (loss).

~~In September 2015, the FASB issued Accounting Standard Update (“ASU”) 2015-16,~~~~“Business Combinations (Topic 805)—Simplifying the Accounting for Measurement-Period Adjustments~~.” ~~ASU 2015-16 requires that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period~~recognition in the reporting period in which the adjustments are identified, including the cumulative effect of the change in provisional amount as if the accounting had been completed at the acquisition date. ASU 2015-16income statement. The new standard is effective for ~~reporting~~annual periods beginning after December 15, 2018, including interim periods within those years, with early adoption permitted. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. Teradyne is currently evaluating the impact of this ASU on its financial position and results of operations.

In November 2015, the FASB issued ASU 2015-17,“Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes.” ASU 2015-17 simplifies the presentation of deferred income taxes by eliminating the separate classification of deferred income tax liabilities and assets into current and noncurrent amounts in the balance sheet. The amendments in the update require that all deferred tax liabilities and assets be classified as noncurrent in the balance sheet. This ASU is effective for annual periods beginning after December 15, 2016, and interim periods within those years and may be applied ~~prospectively.~~either prospectively or retrospectively to all periods presented. Early adoption is permitted. Teradyne early adopted this ASU prospectively in the ~~three months ended October 4, 2015. Adoption~~first quarter of ~~this ASU did not have a material impact on Teradyne’s financial position and results of operations.~~2016.

OnIn April 7, 2015, the FASB issued ASU 2015-03,“Simplifying the Presentation of Debt Issuance Costs,” which requires debt issuance costs to be presented in the balance sheet as a direct deduction from the carrying value of the associated debt liability, consistent with the presentation for debt discount. ASU 2015-03 does not specifically address requirements for the presentation or subsequent measurement of debt issuance costs related to line-of-credit arrangements. On August 8, 2015, the FASB issued ASU 2015-15, “Interest—Imputation of Interest (Subtopic 835-30)” clarifying that debt issuance costs related to line-of-credit arrangements could be presented as an asset and amortized over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. ~~For~~ Teradyne adopted this ASU in the ~~standard is effective for financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within those years.

In May 2014, the FASB issued ASU 2014-09,“Revenue from Contracts with Customers (Topic 606),” which will replace numerous requirements in U.S. GAAP, including industry-specific requirements, and provide companies with a single revenue recognition model for recognizing revenue from contracts with customers. The core principle of the new standard is that a company should recognize revenue to show the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled to in exchange for those goods or services. In August 2015, FASB issued ASU 2015-14, which deferred the effective date of the new revenue standard by 1one year. For Teradyne, the standard will be effective in the

first quarter of 2018. Early adoption is permitted but not before the original effective date (that is, annual periods beginning after December 15, 2016). The two permitted transition methods under the new standard are the full retrospective method, in which case the standard would be applied to each prior reporting period presented, or the modified retrospective method, in which case the cumulative effect of applying the standard would be recognized at the date of initial application. Teradyne has not yet selected a transition method. Teradyne is currently evaluating the impact of this ASU on its financial position and results of operations.

On June 11, 2015, Teradyne acquired all of the outstanding equity of Universal Robots located in Odense, Denmark. Universal Robots is the leading supplier of collaborative robots which are low-cost, easy-to-deploy and simple-to-program robots that work side by side with production workers to improve quality, ~~and~~ increase manufacturing ~~efficiency.~~efficiency and decrease manufacturing costs. Universal Robots is a separate operating and reportable segment, Industrial Automation.

The total purchase price of ~~$317.7~~$315.4 million consisted of ~~$283.9~~$283.8 million of cash paid and ~~$33.8~~$31.6 million of contingent consideration, measured at fair value. The contingent consideration was valued using a Monte Carlo simulation based on the following key inputs: (1) forecasted revenue; (2) forecasted EBITDA; (3) revenue volatility; (4) EBITDA volatility; and (5) discount rate. The contingent consideration is payable upon the achievement of certain thresholds and targets for earnings before income taxes, depreciation and amortization (“EBITDA”) for calendar year 2015, revenue for the period from July 1, 2015 to December 31, 2017 and revenue for the period from July 1, 2015 to December 31, 2018. The maximum amount of contingent consideration that could be paid is $65 million.

~~The valuation~~ Based on Universal Robots’ calendar year 2015 EBITDA results, in the first quarter of 2016, Teradyne paid $15 million or 100% of the eligible EBITDA contingent consideration ~~utilized~~amount.

In the ~~following assumptions: (1) probability~~fourth quarter of ~~meeting each target; (2) expected timing of meeting each target;~~2015, Teradyne finalized the valuation and (3) discount rate reflecting the risk associated with the expected payments. The probabilities and timing for each target were estimated based on a review of the historical and projected results. Discount rates of 6 percent, 8 percent and 10 percent, respectively, were based on corporate bond yields adjustedpurchase price allocation for the ~~level~~acquisition which resulted in a $5.4 million decrease in goodwill as a result of ~~difficulty to achieve and~~a $2.2 million decrease in the ~~term~~fair value of ~~the earn out payment. A significant portion of the risk in achieving the~~ contingent consideration, ~~was captured~~a $1.6 million increase in ~~the probabilities assigned to meeting each target.~~intangible assets and a $1.6 million decrease in acquired liabilities.

The Universal Robots acquisition was accounted for as a business combination and, accordingly, the results have been included in Teradyne’s consolidated results of operations from the date of acquisition. The allocation of the total purchase price to Universal Robots’ net tangible liabilities and identifiable intangible assets was based on their estimated fair values as of the acquisition date. The excess of the purchase price over the identifiable intangible assets and net tangible liabilities in the amount of ~~$227.0~~$221.1 million was allocated to goodwill, which is not deductible for tax purposes. The purchase price allocation is preliminary pending the final determination of the fair value of contingent consideration, acquired assets and assumed liabilities. Teradyne expects to finalize the purchase price calculation in the fourth quarter of 2015.

The following table represents the ~~preliminary~~final allocation of the purchase price:


	Purchase Price Allocation			Purchase Price Allocation
	(in thousands)			(in thousands)
Goodwill	$	227,021		$	221,128
Intangible assets		119,950			121,590

Teradyne estimated the fair value of intangible assets using the income and cost approaches. Acquired intangible assets are amortized on a straight-line basis over their estimated useful lives. Components of these intangible assets and their estimated useful lives at the acquisition date are as follows:

~~For the three months ended October 4, 2015, Universal Robots contributed $16.1 million of revenues and had a $(4.8) million loss from operations before income taxes.~~

~~For the period from June 12, 2015 to October 4, 2015, Universal Robots contributed $19.8 million of revenues and had a $(6.5) million loss from operations before income taxes.~~


	Fair Value		Estimated Useful Life
	(in thousands)		(in years)
Developed technology	$	89,240		4.9
Trademarks and tradenames		22,920		10.0
Customer relationships		9,430		2.0

Total intangible assets	$	121,590		5.6

The following unaudited pro forma information gives effect to the acquisition of Universal Robots as if the acquisition occurred on January 1, 2014. The unaudited pro forma results are not necessarily indicative of what actually would have occurred had the acquisition been in effect for the periods presented:

Pro forma results for the nine months ended October 4, 2015 were adjusted to exclude $1.6 million of non-recurring expense related to the fair value adjustment to acquisition-date inventory and $1.0 million of acquisition related costs incurred in 2015.

Pro forma results for the nine month ended September 28, 2014, were adjusted to include $1.6 million of non-recurring expense related to the fair value adjustment to acquisition-date inventory and $1.0 million of acquisition related costs.

On October 31, 2014, Teradyne acquired substantially all of the assets and liabilities of Avionics Interface Technologies, LLC (“AIT”) located in Omaha, Nebraska. AIT is a supplier of equipment for testing state-of-the-art data communication buses. The acquisition of AIT complements Teradyne’s Defense/Aerospace line of bus test instrumentation for commercial and defense avionics systems. AIT is included in Teradyne’s System Test segment.

The total purchase price of $21.2 million consisted of $19.4 million of cash paid and $1.8 million of contingent consideration, measured at fair value. The contingent consideration is payable upon achievement of certain revenue and gross margin targets in 2015 and 2016. The maximum amount of contingent consideration that could be paid is $2.1 million.

The valuation of the contingent consideration utilized the following assumptions: (1) probability of meeting each target; (2) expected timing of meeting each target; and (3) discount rate reflecting the risk associated with the expected payments. The probabilities and timing for each target were estimated based on a review of the historical and projected results. A discount rate of 4.7 percent was selected based on the estimated cost of debt for the business. A significant portion of the risk in achieving the contingent consideration was captured in the probabilities assigned to meeting each target.

In the three and nine months ended October 4, 2015, the fair value of contingent consideration for the earn-out in connection with the acquisition of AIT was reduced by $1.0 million due to a decrease in the revenue probabilities in the periods of 2015 and 2016.

The AIT acquisition was accounted for as a business combination and, accordingly, the results have been included in Teradyne’s consolidated results of operations from the date of acquisition. The allocation of the total purchase price to AIT’s net tangible and identifiable intangible assets was based on their estimated fair values as of the acquisition date. The excess of the purchase price over the identifiable intangible and net tangible assets in the amount of $10.5 million was allocated to goodwill, which is deductible for tax purposes.

Teradyne estimated the fair value of intangible assets using the income approach. Acquired intangible assets are amortized on a straight-line basis over their estimated useful lives. Components of these intangible assets and their estimated useful lives at the acquisition date are as follows:

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

Teradyne accounts for its investments in debt and equity securities in accordance with the provisions of Accounting Standards Codification (“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. As of ~~October 4, 2015,~~April 3, 2016, Teradyne’s investments in debt and equity securities were classified as available-for-sale and recorded at their fair market value.

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:

Teradyne uses the market and income approach techniques to value its financial instruments and there were no changes in valuation techniques during the three ~~and nine~~ months ended ~~October 4, 2015.~~April 3, 2016. 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 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.~~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 is considered a Level 2 ~~input.~~input; or

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.

Teradyne’s available-for-sale ~~fixed income~~debt and equity securities are classified as Level 1 and Level 2. ~~Contingent~~Acquisition-related contingent consideration is classified as Level 3. Teradyne’s contingent consideration is valued using a Monte Carlo simulation model or a probability weighted discounted cash flow model. The ~~vast~~ majority of Level 2 securities are fixed income securities priced by third party pricing vendors. These pricing vendors utilize the most recent observable market information in pricing these securities or, if specific prices are not available, use other observable inputs like market transactions involving identical or comparable securities.

Realized gains recorded in the three months ended April 3, 2016 and April 5, 2015 were $0.2 million and $0.5 million, respectively. Realized losses recorded in the ~~nine~~three months ended ~~October 4, 2015~~April 3, 2016 were $0.2 million. There were no realized losses recorded in the three ~~and nine~~ months ended September 28, 2014. Realized gains recorded in the three and nine months ended October 4, 2015 were $0.4 million and $1.4 million, respectively. Realized gains recorded in the three and nine months ended September 28, 2014 were $1.0 million and $1.7 million, respectively.April 5, 2015. Realized gains are included in interest income and realized losses are included in interest expense. Unrealized gains and losses are included in accumulated other comprehensive income (loss). The cost of securities sold is based on the specific identification method.

During the ~~nine~~three months ended ~~October 4,~~April 3, 2016 and April 5, 2015, ~~and September 28, 2014,~~ there were no transfers in or out of Level 1, Level 2 or Level 3 financial instruments.

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 ~~October 4, 2015~~April 3, 2016 and December 31, ~~2014.~~2015.

Teradyne reviews its investments to identify and evaluate investments that have an indication of possible impairment. Based on this review, Teradyne determined that the unrealized losses related to these investments, at ~~October 4, 2015~~April 3, 2016 and December 31, ~~2014,~~2015, were temporary.

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 monetary assets and liabilities. 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 value of monetary assets and liabilities denominated in foreign currencies.

The notional amount of foreign currency forward contracts was ~~$91.5~~$138.5 million and ~~$73.0~~$114.1 million at ~~October 4, 2015~~April 3, 2016 and December 31, ~~2014,~~2015, respectively. The fair value of the outstanding contracts was ~~$0.0 million and~~ a loss of ~~$0.1~~$0.2 million and $0.0 million at ~~October 4, 2015~~April 3, 2016 and December 31, ~~2014,~~2015, respectively.

In the three and nine months ended October 4, 2015, Teradyne recorded a net realized loss of $0.8 million and $2.7 million, respectively, related to foreign currency forward contracts hedging net monetary positions.

InFor the three months ended ~~September 28, 2014,~~April 3, 2016 and April 5, 2015, Teradyne recorded a net realized ~~gain~~losses of ~~$0.2~~$3.3 million ~~related to foreign currency forward contracts hedging net monetary positions. In the nine months ended September 28, 2014, Teradyne recorded a net realized loss of $1.6~~and $3.4 million, respectively, related to foreign currency forward contracts hedging net monetary positions. Gains and losses on foreign currency forward contracts and foreign currency remeasurement gains and losses on monetary assets and liabilities are included in other (income) expense, net.

assets and liabilities denominated in foreign currencies were $0.4 million. For the nine months ended September 28, 2014, net gains from the remeasurement of monetary assets and liabilities denominated in foreign currencies were $0.9 million.

~~See Note F: “Debt” regarding derivatives related to the convertible senior notes.~~

On April 27, 2015, Teradyne entered into a Credit Agreement (the “Credit Agreement”) with Barclays Bank PLC, as administrative agent and collateral agent, and the lenders party thereto. The Credit Agreement provides for a five-year, senior secured revolving credit facility of up to $350 million (the “Credit Facility”). The Credit Agreement further provides that, subject to customary conditions, Teradyne may seek to obtain from existing or new lenders incremental commitments under the Credit Facility in an aggregate principal amount not to exceed ~~$150.0~~$150 million.

Proceeds from the Credit Facility may be used for general corporate purposes and working capital. Teradyne incurred $2.3 million in costs related to the revolving credit facility. These costs are being amortized over the five year term of the revolving credit facility and are included in interest expense in the statement of operations. As of ~~November~~May 13, ~~2015,~~2016, Teradyne has not borrowed any funds under the Credit Facility.

The interest rates applicable to loans under the Credit Facility are, at Teradyne’s option, equal to either a base rate plus a margin ranging from 0.00% to 1.00% per annum or LIBOR plus a margin ranging from 1.00% to 2.00% per annum, based on the Consolidated Leverage Ratio of Teradyne and its Restricted Subsidiaries. In addition, Teradyne will pay a commitment fee on the unused portion of the commitments under the Credit Facility ranging from 0.125% to 0.350% per annum, based on the then applicable Consolidated Leverage Ratio.

Teradyne is not required to repay any loans under the Credit Facility prior to maturity, subject to certain customary exceptions. Teradyne is permitted to prepay all or any portion of the loans under the Credit Facility prior to maturity without premium or penalty, other than customary LIBOR breakage costs.

The Credit Agreement contains customary events of default, representations, warranties and affirmative and negative covenants that, among other things, limit Teradyne’s and its Restricted Subsidiaries’ ability to sell assets, grant liens on assets, incur other secured indebtedness and make certain investments and restricted payments, all subject to exceptions set forth in the Credit Agreement. The Credit Agreement also requires Teradyne to satisfy two financial ratios measured as of the end of each fiscal quarter: a consolidated leverage ratio and an interest coverage ratio. As of ~~October 4, 2015,~~April 3, 2016, Teradyne was in compliance with all covenants.

The Credit Facility is guaranteed by certain of Teradyne’s domestic subsidiaries and collateralized by assets of Teradyne and such subsidiaries, including a pledge of 65% of the capital stock of certain foreign subsidiaries.

On March 31, 2009, Teradyne entered into an underwriting agreement regarding a public offering of $175.0 million aggregate principal amount of 4.50% convertible senior notes due March 15, 2014 (the “Notes”). On April 1, 2009, the underwriters exercised their option to purchase an additional $15.0 million aggregate principal amount of the Notes for a total aggregate principal amount of $190.0 million. The Notes bore interest at a rate of 4.50% per annum, payable semiannually in arrears on March 15 and September 15 of each year, beginning on September 15, 2009. The Notes had a maturity date of March 15, 2014. Substantially all of the Notes were converted prior to March 15, 2014 and were “net share settled,” meaning that the holders received, for each $1,000 in principal amount of Notes, $1,000 in cash and approximately 131.95 shares of Teradyne common stock (calculated by taking 182.65 shares, being the fixed number specified in the Notes purchase agreement, less 50.7 shares). The 50.7 shares were determined, as specified in the Notes purchase agreement, by dividing the $1,000 principal amount by the $19.74 average trading price of Teradyne’s common stock over the 25 day trading period from February 5, 2014 to March 12, 2014.

Teradyne satisfied the Notes “net share settlement” by paying the aggregate principal amount of $190 million in cash and issuing 25.1 million shares of common stock. On March 13, 2014, Teradyne exercised its call option agreement entered into with Goldman, Sachs & Co. (the “hedge counterparty”) at the time of issuance of the Notes and received 25.1 million shares of Teradyne’s common stock, which Teradyne retired.

From June 17, 2014 to September 17, 2014, the hedge counterparty exercised its warrant agreement entered into with Teradyne at the time of issuance of the Notes. The warrants were net share settled. In 2014, Teradyne issued 21.2 million shares of its common stock for warrants exercised at a weighted average strike price of $7.6348 per share.

~~The interest expense on Teradyne’s convertible senior notes for the nine months ended October 4, 2015 and September 28, 2014 was as follows:~~

Prepayments consist of the following and are included in prepayments on the balance sheet:

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

Teradyne grants performance-based restricted stock units (“PRSUs”) to its executive officers with a performance metric based on relative total shareholder return (“TSR”). For TSR grants issued in 2014 and 2015, Teradyne’s three-year TSR performance is measured against the Philadelphia Semiconductor Index. For TSR grants issued in January 2016, Teradyne’s three-year TSR performance will be measured against the ~~Philadelphia Semiconductor Index, which consists of thirty companies in the semiconductor device and capital equipment industries.~~New York Stock Exchange (“NYSE”) Composite Index. The final number of TSR PRSUs that vest will vary based upon the level of performance achieved from 200% ~~of the target shares~~ to 0% of the target shares. The TSR PRSUs will vest upon the three-year anniversary of the grant date. The TSR PRSUs are valued using a Monte Carlo simulation model. The number of units expected to be earned, based upon the achievement of the TSR market condition, is factored into the grant date Monte Carlo valuation. Compensation expense is recognized on a straight-line basis over the three-year service period. Compensation expense is recognized regardless of the eventual number of units that are earned based upon the market condition, provided the executive officer remains an employee at the end of the three-year period. Compensation expense is reversed if at any time during the three-year service period the executive officer is no longer an employee, subject to the retirement and termination eligibility provisions noted below.

In January 2016, Teradyne granted PRSUs to its executive officers with a performance metric based on three-year cumulative non-GAAP profit before interest and tax (“PBIT”). Non-GAAP PBIT is a financial measure equal to GAAP income from operations less restructuring and other, net; amortization of acquired intangible assets; acquisition and divestiture related charges or credits; pension actuarial gains and losses; and other non-recurring gains and charges. The final number of PBIT PRSUs that vest will vary based upon the level of performance achieved from 200% to 0% of the target shares. The PBIT PRSUs will vest upon the three-year anniversary of the grant date. Compensation expense is recognized on a straight-line basis over the three-year service period. Compensation expense is recognized based on the number of units that are earned based upon the three year Teradyne PBIT as a percent of Teradyne’s revenue, provided the executive officer remains an employee at the end of the three-year period subject to the retirement and termination eligibility provisions noted below.

Beginning with PRSUs granted in January 2014, if the recipient’s employment ends prior to the determination of the performance percentage due to (1) permanent disability or death or (2) retirement or termination other than for cause, after attaining both at least age sixty and at least ten years of service, then all or a portion of the recipient’s PRSUs (based on the actual performance percentage achieved on the determination date) will vest on the date the performance percentage is determined. Except as set forth in the preceding sentence, no ~~TSR~~ PRSUs will vest if the executive officer is no longer an employee at the end of the three-year period.

The TSR PRSUs are valued using a Monte Carlo simulation model. The number of units expected to be earned, based upon the achievement of the TSR market condition, is factored into the grant date Monte Carlo valuation. Compensation expense is recognized on a straight-line basis over the three-year service period. Compensation expense is recognized regardless of the eventual number of units that are earned based upon the

market condition, provided the executive officer remains an employee at the end of the three-year period. Compensation expense is reversed if at any time during the three-year service period the executive officer is no longer an employee, subject to the retirement and termination eligibility provisions noted above.

During the ~~nine~~three months ended ~~October 4,~~April 3, 2016 and April 5, 2015, ~~and September 28, 2014,~~ Teradyne granted ~~0.2~~0.1 million and ~~0.1~~0.2 million TSR PRSUs, respectively, with a grant date fair value of ~~$18.21~~$20.29 and ~~$22.06,~~$18.21, respectively. The fair value was estimated using the Monte Carlo simulation model with the following assumptions:


	For the Nine Months Ended						For the Three Months Ended

Expected volatility was based on the historical volatility of Teradyne’s stock and the NYSE Composite Index for the 2016 grant and Philadelphia Semiconductor Index for the 2015 grant, over the most recent three year period. The risk-free interest rate was determined using the U.S. Treasury yield curve in effect at the time of grant. Dividend yield was based upon an estimated annual dividend amount of $0.24 per share divided by Teradyne’s stock price on the grant date of $19.43 for the 2016 grant and $18.10 for the 2015 ~~grants and $19.16 for 2014 grants.~~grant.

During the ~~nine~~three months ended ~~October 4, 2015,~~April 3, 2016, Teradyne granted ~~1.5~~0.1 million PBIT PRSUs with a grant date fair value of $18.71.

During the three months ended April 3, 2016, Teradyne granted 1.2 million of service-based restricted stock unit awards to employees at a weighted average grant date fair value of ~~$17.27~~$18.47 and 0.1 million of service-based stock options to executive officers at a weighted average grant date fair value of ~~$4.43.~~$5.30.

During the ~~nine~~three months ended ~~September 28, 2014,~~April 5, 2015, Teradyne granted ~~1.7~~1.4 million of service-based restricted stock unit awards to employees at a weighted average grant date fair value of ~~$19.09~~$17.14 and 0.1 million of service-based stock options to executive officers at a weighted average grant date fair value of ~~$5.49.~~$4.43.

Restricted stock unit awards granted to employees vest in equal annual installments over four years. Stock options vest in equal annual installments over four years and have a term of seven years from the date of grant.

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


	For the Nine Months Ended						For the Three Months Ended
	October 4, 2015			September 28, 2014			April 3, 2016			April 5, 2015
Expected life (years)		4.0			4.0			5.0			4.0
Risk-free interest rate		1.1	%		1.2	%		1.4	%		1.1	%
Volatility-historical		33.4	%		38.8	%		32.9	%		33.4	%
Dividend yield		1.33	%		1.25	%		1.24	%		1.33	%

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 interest rate was determined using the U.S. Treasury yield curve in effect at the time of grant. Dividend yield was based upon an estimated annual dividend amount of $0.24 per share divided by Teradyne’s stock price on the grant date, of $19.43 for the 2016 grant and $18.10 for the 2015 ~~grants and $19.16 for 2014 grants.~~grant.

Effective January 31, 2014, Michael Bradley retired as Chief Executive Officer of Teradyne. On January 22, 2014, Teradyne entered into an agreement (the “Retirement Agreement”) with Mr. Bradley. Under the Retirement Agreement, Mr. Bradley’s unvested restricted stock units and stock options granted prior to his retirement date will continue to vest in accordance with their terms through January 31, 2017; and any vested options or options that vest during that period may be exercised for the remainder of the applicable option term. In the Retirement Agreement, Mr. Bradley agreed to be bound by non-competition and non-solicitation restrictions through January 31, 2017. Mr. Bradley continues to serve on Teradyne’s Board of Directors. In the three months ended March 30, 2014, Teradyne recorded a one-time charge to stock-based compensation expense of $6.6 million related to the Retirement Agreement.

The following table sets forth the computation of basic and diluted net income per common share:

The computation of diluted net income per common share for the three ~~and nine~~ months ended ~~October 4,~~April 3, 2016 excludes the effect of the potential exercise of stock options to purchase approximately 0.3 million shares because the effect would have been anti-dilutive.

The computation of diluted net income per common share for the three months ended April 5, 2015 excludes the effect of the potential exercise of stock options to purchase approximately 0.2 million shares because the effect would have been anti-dilutive.

The computation of diluted net income per common share for the three and nine months ended September 28, 2014 excludes the effect of the potential exercise of stock options to purchase approximately 0.3 million shares because the effect would have been anti-dilutive.

During the three months ended ~~October 4, 2015,~~April 3, 2016, Teradyne recorded ~~a $1.0~~an expense of $1.2 million ~~gain from~~for the ~~decrease~~increase in the fair value of the ~~AIT~~Universal Robots contingent consideration ~~liability, partially offset by $0.1 million of acquisition costs related to Universal Robots.~~

During the nine months ended October 4, 2015, Teradyne recorded a $2.6 million gain from the decrease in the fair value of contingent consideration liability, of which $1.6 million was related to the ZTEC acquisition and $1.0 million was related to the AIT acquisition, partially offset by $1.1 million of acquisition costs related to Universal Robots.

~~During the three and nine months ended September 28, 2014, Teradyne recorded a $0.6 million fair value adjustment to decrease the ZTEC acquisition contingent consideration.~~liability.

During the three ~~and nine~~ months ended ~~October 4, 2015,~~April 3, 2016, Teradyne recorded $1.1 million and $1.4 million, respectively, of severance charges related to headcount reductions of 18 and 22 people, respectively, primarily in System Test. During the nine months ended September 28, 2014, Teradyne recorded $0.8$0.4 million of severance charges related to headcount reductions of 3012 people, primarily in ~~Wireless~~Semiconductor Test.

ASC 715, “Compensation—Retirement Benefits” 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. The pension asset or liability represents a difference between the fair value of the pension plan’s assets and the projected benefit obligation.

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.

In the ~~nine~~three months ended ~~October 4, 2015,~~April 3, 2016, Teradyne contributed ~~$1.9~~$0.7 million to the U.S. supplemental executive defined benefit pension plan and $0.6 million to certain qualified plans for non-U.S. subsidiaries.

For the three ~~and nine~~ months ended ~~October 4,~~April 3, 2016 and April 5, 2015, ~~and September 28, 2014,~~ Teradyne’s net periodic pension (income) cost was comprised of the following:

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,~~ 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.

For the three ~~and nine~~ months ended ~~October 4,~~April 3, 2016 and April 5, 2015, ~~and September 28, 2014,~~ Teradyne’s net periodic postretirement benefit income was comprised of the following:

As of ~~October 4, 2015,~~April 3, 2016, Teradyne had entered into purchase commitments for certain components and materials. The purchase commitments covered by the agreements aggregate to approximately ~~$219.6~~$235.3 million, of which ~~$214.2~~$233.7 million is for less than one year.

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.

The effective tax rate for the three months ended ~~October 4,~~April 3, 2016 and April 5, 2015 was 12.6% and ~~September 28, 2014 was 18.3% and 17.6%~~22.7%, respectively. The effective tax rates for these periods were lower than the expected federal statutory rate of 35% primarily because of the favorable effect of statutory rates applicable to income earned outside the United States. The tax rate for the three months ended ~~October 4, 2015~~April 3, 2016 was ~~increased~~also reduced by the benefit from U.S. research and development tax credits, partially offset by additions to the uncertain tax positions for transfer pricing, both of which are included in the projected annual effective tax ~~rate, partially offset by $3.3~~rate. Discrete tax benefits recorded in the quarter amounted to $2.5 million of ~~discrete tax benefits composed of $1.8~~which $1.2 million ~~of benefit attributable~~resulted from non-taxable foreign exchange gains, $0.9 million related to ~~a United States Tax Court opinion regarding intercompany cost sharing arrangements, $0.6 million of reductions in uncertain tax positions resulting from the expiration of statutes~~marketable securities and ~~$0.9~~$0.4 million from other discrete tax benefits.

The tax rate for the three months ended ~~September 28, 2014~~April 5, 2015 was ~~increased~~reduced by ~~$5.6~~a $1.2 million of discrete tax ~~expense composed of $7.2~~benefit related to non-taxable foreign exchange gains and a $0.5 million ~~of additions to the uncertain tax positions for transfer pricing net of $0.9 million of~~ discrete tax ~~benefits resulting from increases in credit carry forwards and $0.7 million from other discrete tax benefits.~~

The effective tax rate for the nine months ended October 4, 2015 and September 28, 2014 was 20.9% and 15.9%, respectively. The effective tax rates for these periods were lower than the expected federal statutory rate of 35% primarily because of the favorable effect of statutory rates applicablebenefit related to income earned outside the United States. The tax rate for the nine months ended October 4, 2015 was increased by additions to the uncertain tax positions for transfer pricing included in the projected annual effective tax rate, partially offset by $5.0 million of discrete tax benefits composed of $1.8 million of benefit attributable to a United States Tax Court opinion regarding intercompany cost sharing arrangements, $1.3 million of reductions in uncertain tax positions resulting from the expiration of statutes and the settlement of an audit, $0.9 million from disqualifying dispositions of incentive stock options and employee stock purchase plan ~~shares and $1.0 million from other discrete tax benefits.~~

The tax rate for the nine months ended September 28, 2014 was increased by $2.6 million of discrete tax expense composed of $7.2 million of additions to the uncertain tax positions for transfer pricing net of $1.7 million of discrete tax benefits from disqualifying dispositions of incentive stock options and employee stock purchase plan shares, $0.9 million of discrete tax benefits resulting from increases in credit carry forwards and $2.0 million from other discrete tax benefits.shares.

On a quarterly basis, Teradyne evaluates the realizability of the deferred tax assets by jurisdiction and assesses the need for a valuation allowance. As of ~~October 4, 2015,~~April 3, 2016, Teradyne believes that it will ultimately realize the deferred tax assets recorded on the condensed consolidated balance sheet. However, should Teradyne believe that it is more likely than not that the deferred tax assets would not be realized, the tax provision would increase in the period in which Teradyne determined that the realizability was not likely. Teradyne considers the probability of future taxable income and historical profitability, among other factors, in assessing the realizability of the deferred tax assets.

As of ~~October 4, 2015~~April 3, 2016 and December 31, ~~2014,~~2015, Teradyne had ~~$33.3~~$35.2 million and ~~$30.4~~$33.7 million, respectively, of reserves for uncertain tax positions. The ~~$2.9~~$1.5 million net increase in reserves for uncertain tax positions relates primarily to transfer pricing ~~exposures.~~exposure.

As of ~~October 4, 2015,~~April 3, 2016, Teradyne ~~anticipated~~estimates that it is reasonably possible that the ~~liability for uncertain~~balance of unrecognized tax ~~positions could~~benefits may decrease by approximately ~~$0.1~~$9.1 million ~~over~~in the next twelve months, ~~primarily~~ as a result of ~~the expiration~~a lapse of statutes of ~~limitations.~~limitation and the settlement of a tax audit. The ~~potential~~estimated decrease is ~~related~~composed primarily of reserves relating to federal tax credits and transfer ~~pricing exposures.~~pricing.

Teradyne recognizes interest and penalties related to income tax matters in income tax expense. As of ~~October 4, 2015~~April 3, 2016 and December 31, ~~2014, $0.3~~2015, $0.8 million and ~~$0.6~~$0.5 million, respectively, of interest and penalties were included in the reserve for uncertain tax positions. For the three months ended April 3, 2016, expense of $0.3 million was recorded for interest and penalties related to income tax items. For the three months ended April 5, 2015, interest and penalties related to income tax items were not material.

Teradyne qualifies for a tax holiday in Singapore by fulfilling the requirements of an agreement with the Singapore Economic Development Board under which certain headcount and spending requirements must be met. The tax savings due to the tax holiday for the ~~nine~~three months ended ~~October 4, 2015~~April 3, 2016 was ~~$9.9~~$2.6 million, or ~~$0.05~~$0.01 per diluted share. The tax savings due to the tax holiday for the ~~nine~~three months ended ~~September 28, 2014~~April 5, 2015 was ~~$12.3~~$1.1 million ~~or $0.05~~and the impact of the tax holiday on earnings per ~~diluted share.~~share was not material. The tax holiday is ~~currently expected~~scheduled to expire on December 31, ~~2015. Teradyne is in discussion with the Singapore Economic Development Board with respect to extension of the tax holiday for periods after December 31, 2015.~~2020.

Teradyne has four operating segments (Semiconductor Test, ~~Wireless~~System Test, ~~System~~Wireless Test, and Industrial Automation), 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 ~~Wireless Test segment includes operations related to the design, manufacturing and marketing of wireless test products and services. The~~ System Test segment includes operations related to the design, manufacturing and marketing of products and services for defense/aerospace instrumentation test, storage test and circuit-board test. The Wireless Test segment includes operations related to the design, manufacturing and marketing of wireless test products and services. The Industrial Automation segment includes operations related to the design, manufacturing and marketing of collaborative robots. 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 in effect are described in Note B: “Accounting Policies” in Teradyne’s Annual Report on Form 10-K for the year ended December 31, ~~2014, unless updated in this form 10-Q, where applicable.~~2015.

Teradyne is still in the process of assessing the total impact of the damage. The net book value of the inventory and fixed assets at the Kumamoto location is approximately $17 million. With respect to the location, Teradyne has $10 million of earthquake insurance with a deductible of approximately $2.5 million. Teradyne is temporarily transferring some operations to other facilities in Japan and elsewhere while Teradyne’s Kumamoto operations are restored.

Item 2:

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~~“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~~forward-looking statements involve risks and uncertainties, including those detailed in our 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, ~~2014.~~2015. 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~~forward-looking statements to reflect actual results or changes in factors or assumptions affecting ~~forward- looking~~forward-looking statements, except as may be required by law.

We are a leading global supplier of automation equipment for test and industrial applications. We design, develop, manufacture and sell automatic test systems ~~and solutions~~ used to test semiconductors, wireless products, ~~hard disk drives~~data storage and ~~circuit boards~~complex electronics systems in the consumer electronics, wireless, automotive, industrial, computing, communications, and aerospace and defense industries. Our industrial automation products include collaborative robots used by global manufacturing and light industrial customers to improve quality, increase manufacturing efficiency and decrease manufacturing costs. Our automatic test equipment and industrial automation products and services include:

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, and distributors that sell collaborative robots.

On June 11, 2015, we acquired Universal Robots A/S (“Universal Robots”) for approximately $284 million of cash plus up to an additional $65 million of cash if certain performance targets are met extending through 2018. Universal Robots is the leading supplier of collaborative robots which are low-cost, easy-to-deploy and simple-to-program robots that work side by side with production workers to improve quality and increase manufacturing efficiency. Universal Robots is a separate operating and reportable segment, Industrial Automation. The acquisition of Universal Robots provides a growth engine to our business and complements our existing System Test and Wireless Test segments.

In October 2014, we acquired Avionics Interface Technologies, LLC (“AIT”), a supplier of equipment for testing state-of-the-art data communication buses. The acquisition of AIT complements our Defense/Aerospace line of bus test instrumentation for commercial and defense avionics systems. AIT is included in our System Test segment.

We believe our recent acquisitions have enhanced our opportunities for growth. We intend to continue to invest in our business, grow market share in our markets and expand further our addressable markets while tightly managing our costs.

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~~because our customers often delay or accelerate purchases in reaction to changes in their businesses and to demand fluctuations in the semiconductor and electronics industries. Historically, these demand fluctuations have resulted in significant variations in our results of operations. The sharp swings in the semiconductor and electronics industries ~~in recent years~~ have generally affected the semiconductor and electronics test equipment and services industries more significantly than the overall capital equipment sector.

In recent years, this cyclical demand has become an even/odd year trend where demand has increased in even years and decreased in odd years due principally to demand swings in the ~~fourth quarter~~mobility market of ~~2014, we performed~~our Semiconductor Test business. In 2015, the even/odd year trend continued, but had less of an impact on our annual ~~goodwill impairment~~revenue due to the sale in 2015 of testers that were previously leased to customers in 2014. We expect the

even/odd year demand trend in the mobility market to most likely lessen in the future due to slower smart phone unit growth, along with rising device complexity and the reduced impact of parallel test ~~and recorded a goodwill impairment charge of $98.9 million~~ in our ~~Wireless~~Semiconductor Test ~~segment as a result of decreased projected demand attributable to~~business.

On April 16, 2016, an ~~estimated smaller future wireless test market due to reuse of wireless test equipment, price competition~~earthquake in Kumamoto, Japan damaged our facility. The facility, which is used for engineering, production, and ~~different testing techniques. Further reductions~~support operations, sustained heavy damage. We are still in the ~~size~~process of assessing the total impact of the ~~wireless test market may occur, which may result~~damage. The net book value of the inventory and fixed assets at the Kumamoto location is approximately $17 million. With respect to the location, we have $10 million of earthquake insurance with a deductible of approximately $2.5 million. We are temporarily transferring some operations to other facilities in ~~additional goodwill impairment charges, increased risk of excess~~Japan and ~~obsolete inventories, asset write-offs and restructuring charges.~~elsewhere while our Kumamoto operations are restored.

We have identified the policies which are critical to understanding our business and our results of operations. Except for below, there have been no significant changes during the ~~nine~~three months ended ~~October 4, 2015~~April 3, 2016 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, ~~2014.~~2015.

We ~~recognize revenues when there is persuasive evidence~~performed our last goodwill impairment test during the fourth quarter 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~~2015. We performed step one of the ~~related receivable~~two step impairment test for our Wireless Test and Defense/Aerospace reporting units and the step zero assessment for our Industrial Automation reporting unit. The step one tests resulted in each of the reporting unit’s fair value exceeding its carrying value by at least 20%.

We estimate the fair value of a reporting unit using the results derived from an income approach, a discounted cash flow analysis, and a market approach using the market comparable method which is ~~reasonably assured. Title~~based on revenue and ~~risk~~earnings multiples from comparable companies. Estimating a reporting unit’s fair value requires significant judgment and assumptions including projected future cash flows, revenue, market size, market growth, Teradyne’s market share, market multiples, discount rates and consideration of ~~loss generally pass~~market valuations of comparable companies. These judgments and assumptions reflect our best estimates, but these items involve inherent uncertainties based on market and customer conditions.

The fair value estimate for our Wireless Test reporting unit involves forecasting the size of the wireless test market in future years and our market share which are significant judgments and assumptions due to our ~~customers upon~~significant customer concentration in our Wireless Test segment. Forecasting the size of the wireless test market in future years and our market share includes estimating end product shipment ~~or at delivery destination point.~~ volumes, new wireless technology introductions and customer buying patterns. As of April 3, 2016 and December 31, 2015, our Wireless Test segment had $262.9 million of goodwill.

In ~~circumstances where either title or risk~~the fourth quarter of ~~loss pass upon destination, acceptance or cash payment,~~2014, we ~~defer revenue recognition until such events occur except when title transfer is tied~~recorded a goodwill impairment charge of $98.9 million in our Wireless Test segment as a result of decreased demand attributable to ~~cash payment outside the United States. Outside the United States, we recognize revenue upon shipment or at delivery destination point, even if we retain a form~~an estimated smaller wireless test market due to reuse of ~~title to products delivered to customers, provided the sole purpose is to enable us to recover the products~~wireless test equipment, price competition and different testing techniques.

Further reductions in the ~~event of customer payment default and the arrangement does not prohibit the customer’s use or resale~~size of the ~~product in the ordinary course of business.~~

~~Our equipment has non-software and embedded software components that function together to deliver the equipment’s essential functionality. Revenue is recognized upon shipment~~wireless test market or ~~at delivery destination point, provided that customer acceptance criteria can be demonstrated prior to shipment. Certain contracts require us to perform tests~~our share of the ~~product to ensure that performance meets the published product specifications or customer requested specifications,~~wireless test market may occur 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 substantiallymay result 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”~~ ~~and ASC 605-25,~~ ~~“Revenue Recognition Multiple-Element Arrangements.”~~ ~~Service revenue is recognized over the contractual period or as services are performed.~~

Our products are generally subject to warranty and the related costs of the warranty are provided for in cost of revenues when product revenue is recognized. We classify shipping and handling costs in cost of revenues.

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

The functional currency for all non-U.S. subsidiaries is the U.S. dollar, except for the Industrial Automation segment for which the local currency is its functional currency. All foreign currency denominated monetary assets and liabilities are re-measured on a monthly basis into the functional currency using exchange rates in effect at the end of the period. All foreign currency denominated non-monetary assets and liabilities are re-measured into the functional currency using historical exchange rates. Net foreign exchange gains and losses resulting from re-measurement are included in other (income) expense, net. For Industrial Automation, assets and liabilities are translated into U.S. dollars using exchange rates in effect at the end of the period. Revenue and expense amounts are translated using an average of exchange rates in effect during the period. Translation adjustments are recorded within accumulated other comprehensive income (loss).additional goodwill impairment charges.

Gross profit as a percent of revenue ~~increased~~decreased by ~~0.9~~2.8 points, ~~primarily as a result~~ of which 3.7 points decrease was related to unfavorable product mix in SOC Semiconductor Test, higher Storage Test sales and lower Wireless Test sales, partially offset by an increase of ~~1.2~~1.6 points ~~related~~due to ~~lower variable compensation and other spending, partially offset by a decrease of 0.3 points related to lower sales in Semiconductor Test.~~higher product volume.

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 twelve quarters for our Semiconductor Test, System Test and Industrial Automation segments and the next four quarters for our Wireless Test segment, is written-down to estimated net realizable value.

During the three months ended ~~October 4, 2015,~~April 3, 2016, we recorded an inventory provision of ~~$3.1~~$4.3 million included in cost of revenues primarily due to downward revisions to previously forecasted demand levels. Of the ~~$3.1~~$4.3 million of total excess and obsolete provisions, ~~$1.7~~$3.7 million was related to Semiconductor Test, ~~$0.9~~$0.6 million was related to Wireless Test, and ~~$0.5~~$0.1 million was related to System Test.

During the three months ended ~~September 28, 2014,~~April 5, 2015, we recorded an inventory provision of ~~$6.4~~$1.4 million included in cost of revenues primarily due to downward revisions to previously forecasted demand levels. Of the ~~$6.4~~$1.4 million of total excess and obsolete provisions, ~~$4.4~~$0.8 million was related to Wireless Test, $0.5 million was related to Semiconductor Test, ~~$1.3 million was related to Wireless Test,~~ and ~~$0.7~~$0.1 million was related to System Test.

During the three months ended ~~October 4,~~April 3, 2016 and April 5, 2015, ~~and September 28, 2014,~~ we scrapped ~~$3.6~~$0.7 million and ~~$11.1~~$0.6 million of inventory, respectively. During the three months ended ~~October 4,~~April 3, 2016 and April 5, 2015, ~~and September 28, 2014,~~ we sold ~~$2.0~~$1.1 million and ~~$6.2~~$1.9 million of previously written-down or written-off inventory, respectively. As of ~~October 4, 2015,~~April 3, 2016, we had inventory related reserves for inventory which had been written-down or written-off totaling ~~$121.1~~$122.9 million.

~~During the three months ended September 28, 2014, we recorded a $0.6 million fair value adjustment to decrease the ZTEC acquisition contingent consideration.~~

~~The effective tax rate for the three months ended October 4, 2015 and September 28, 2014 was 18.3% and 17.6%, respectively.~~

The increase in ~~the effective tax rate is primarily attributable to a projected increase in~~ income subject to tax in the United States as compared to lower rate foreign jurisdictions net of $7.2 million decrease in discrete tax expense related to uncertain tax positions for transfer pricing and $1.8 million of discrete tax benefit attributable to a United States Tax Court opinion regarding intercompany cost sharing arrangements. We are in discussion with the Singapore Economic Development Board with respect to extension of the tax holiday for periods after December 31, 2015.

~~The decrease~~before income taxes in Semiconductor Test revenues of $66.6 million, or 6%, was primarily due to lower SOC product volume, driven by the application processor and microcontroller markets. The increase in Wireless Test revenue of $7.6 million, or 5%, was primarily due to higher ~~cellular test system sales.~~revenues in the application processor and image sensor markets. The increase in income before income taxes in System Test ~~revenue of $35.7 million, or 31%,~~ was primarily due to higher sales in Storage Test of 3.5” hard disk drive testers for cloud storage.

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

~~Our gross profit~~ The decrease in income before income taxes in Wireless Test was ~~as follows:~~

~~Gross profit as a percent of revenue increased by 2.5 points due to product mix and sales of previously leased testers in Semiconductor Test.~~

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 twelve quarters, is written-down to estimated net realizable value.

~~During the nine months ended October 4, 2015, we recorded an inventory provision of $18.9 million included in cost of revenues~~ primarily due to ~~$7.7 million related to downward revisions to previously forecasted demand levels for~~lower revenue driven by lower cellular test system sales. In June 2015, we completed the acquisition of Universal Robots, which is our ~~2.5” hard disk drive testers~~Industrial Automation segment. The loss before income taxes in ~~Storage Test, $6.0 million related to product transition~~Industrial Automation in ~~Semiconductor Test, and $2.1 million related to downward revision to previously forecasted demand levels in Wireless Test. Of~~ the ~~$18.9 million of total excess and obsolete provisions, $8.6 million was related to Semiconductor Test, $8.2 million was related to System Test, and $2.1 million was related to Wireless Test.~~

~~During the nine~~three months ended ~~September 28, 2014, we recorded an inventory provision of $21.5 million included in cost of revenues with $15.3 million~~April 3, 2016, was primarily due to downward revisions to previously forecasted demand levels and $6.2 million related to product transition in Semiconductor Test. Of the $21.5 million of total excess and obsolete provisions, $14.3 million was related to Semiconductor Test, $5.2 million was related to Wireless Test, and $2.0 million was related to System Test.

During the nine months ended October 4, 2015 and September 28, 2014, we scrapped $5.0 million and $14.3 million of inventory, respectively. During the nine months ended October 4, 2015 and September 28, 2014, we sold $6.4 million and $9.8 million of previously written-down or written-off inventory, respectively. As of October 4, 2015, we had inventory related reserves for inventory which had been written-down or written-off totaling $121.1 million. We have no pre-determined timeline to scrap the remaining inventory.

~~The increase of $8.8 million in engineering and development expenses was due primarily to increased spending in Semiconductor Test and higher variable compensation.~~

The decrease of $2.0 million in selling and administrative expenses was due primarily to a one-time $6.6 million stock-based compensation charge related to Michael Bradley’s (retired Chief Executive Officer) Retirement Agreement in the nine months ended September 28, 2014, partially offset by higher variable compensation.

During the nine months ended October 4, 2015, we recorded a $2.6 million gain from the decrease in the fair value of contingent consideration liability, of which $1.6 million was related to the ZTEC acquisition and $1.0 million was related to the AIT acquisition, partially offset by $1.1 million of acquisition costs related to Universal Robots.

~~During the nine months ended September 28, 2014, we recorded a $0.6 million gain from the fair value adjustment to decrease the ZTEC acquisition contingent consideration.~~

~~During the nine months ended October 4, 2015, we recorded $1.4 million of severance charges related to headcount reductions of 22 people, primarily in System Test.~~

~~During the nine months ended September 28, 2014, we recorded $0.8 million of severance charges related to headcount reductions of 30 people, primarily in Wireless Test.~~intangible assets amortization.

The effective tax rate for the ~~nine~~three months ended ~~October 4,~~April 3, 2016 and April 5, 2015 was 12.6% and ~~September 28, 2014 was 20.9% and 15.9%~~22.7%, respectively. The ~~increase~~decrease in the effective tax rate is primarily attributable to a projected ~~increase~~decrease in income subject to tax in the United States as compared to lower rate foreign jurisdictions ~~net of $7.2 million decrease in discrete~~as well as the benefit from U.S. research and development tax expense related to uncertain tax positions for transfer pricing and $1.8 million of discrete tax benefit attributable to a United States Tax Court opinion regarding intercompany cost sharing arrangements.

In January ~~2014 and August 2014,~~2016, our Board of Directors declared a quarterly cash dividend of $0.06 per share. In the ~~nine~~three months ended ~~September 28, 2014,~~April 3, 2016, dividend payments were ~~$24.4 million.~~

~~In January 2015, May 2015, and August 2015, our Board of Directors declared a quarterly cash dividend of $0.06 per share. In the nine months ended October 4, 2015, dividend payments were $38.4~~$12.3 million.

In January 2015, our Board of Directors authorized the repurchase of up to $500 million of common stock of which $300 million ~~of which~~was repurchased in 2015. In 2016, we intend to repurchase ~~in 2015. As of October 4, 2015~~between $100 million and $200 million. During the three months ended April 3, 2016, we repurchased ~~11.9~~1.5 million shares of common stock at an average price of ~~$19.09,~~$18.81, for a total cost of ~~$226.8~~$28.0 million. The cumulative repurchases under this program as of April 3, 2016 totaled 17.1 million shares of common stock for $328.0 million at an average price of $19.17 per share.

While we declared a quarterly cash dividend and authorized a share repurchase program, we may reduce or eliminate the cash dividend or share repurchase program in the future. Future cash dividends and stock repurchases are subject to the discretion of our Board of Directors which will consider, among other things, our earnings, capital requirements and financial condition.

We believe our cash, cash equivalents and marketable securities balance will be sufficient to pay our quarterly dividend, execute our authorized share repurchase program and meet our working capital and expenditure needs for at least the next twelve months. 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. We have ~~approximately $550~~$514 million of cash, cash equivalents and marketable securities outside the U.S. that if repatriated would incur additional taxes. Determination of the additional taxes that would be incurred is not practicable due to uncertainty regarding the remittance structure, the mix of earnings and earnings and profit pools in the year of remittance, and overall complexity of the calculation. Inflation has not had a significant long-term impact on earnings.

As discussed in Note N: “Stock Based Compensation” in our ~~2014~~2015 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.

In ~~September 2015,~~January 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-01,“Financial Instruments—Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities.”This ASU provides guidance for the recognition, measurement, presentation, and disclosure of financial instruments. The new pronouncement revises accounting related to equity investments and the presentation of certain fair value changes for financial liabilities measured at fair value. Among other things, it amends the presentation and disclosure requirements of equity securities that do not result in consolidation and are not accounted for under the equity method. Changes in the fair value of these equity securities will be recognized directly in net income. This pronouncement is effective for fiscal years and interim periods within those years beginning after December 15, 2017. We are currently evaluating the impact of this ASU on our financial position and results of operations.

On March 31, 2016, the FASB issued ~~Accounting Standard Update (“ASU”) 2015-16,~~ASU 2016-09,“~~Business Combinations~~Compensation-Stock Compensation (Topic ~~805)—Simplifying the Accounting for Measurement-Period Adjustments~~.718): Improvements to Employee Share-Based Payment Accounting.” This ASU ~~2015-16 requires that an acquirer recognize adjustments~~changes how companies account for certain aspects of share-based payment awards to ~~provisional amounts that are identified during~~employees, including the ~~measurement period~~accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as classification in the ~~reporting period in which the adjustments are identified, including the cumulative effect~~statement of ~~the change in provisional amount as if the accounting had been completed at the acquisition date. ASU 2015-16~~cash flows. This pronouncement is effective for ~~reporting~~annual periods beginning after December 15, 2016. Early adoption is permitted. We are currently evaluating the impact of this ASU on our financial position and results of operations.

In February 2016, the FASB issued ASU 2016-02,“Leases (Topic 842).” The guidance in this ASU supersedes the lease recognition requirements in Accounting Standards Codification (“ASC”) Topic 840,“Leases.” The new standard establishes a right-of-use (“ROU”) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than twelve months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. The new standard is effective for annual periods beginning after December 15, 2018, including interim periods within those years, with early adoption permitted. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. We are currently evaluating the impact of this ASU on our financial position and results of operations.

In November 2015, the FASB issued ASU 2015-17,“Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes.” ASU 2015-17 simplifies the presentation of deferred income taxes by eliminating the separate classification of deferred income tax liabilities and assets into current and noncurrent amounts in the balance sheet. The amendments in the update require that all deferred tax liabilities and assets be classified as noncurrent in the balance sheet. This ASU is effective for annual periods beginning after December 15, 2016, and interim periods within those years and may be applied ~~prospectively.~~either prospectively or retrospectively to all periods presented. Early adoption is permitted. We early adopted this ASU prospectively in the ~~three months ended October 4, 2015. Adoption~~first quarter of ~~this ASU did not have a material impact on our financial position and results of operations.~~2016.

On April 7, 2015, the FASB issued ASU 2015-03,“Simplifying the Presentation of Debt Issuance Costs,” which requires debt issuance costs to be presented in the balance sheet as a direct deduction from the carrying value of the associated debt liability, consistent with the presentation for debt discount. ASU 2015-03 does not specifically address requirements for the presentation or subsequent measurement of debt issuance costs related to line-of-credit arrangements. On August 8, 2015, the FASB issued ASU 2015-15, “Interest—Imputation of Interest (Subtopic 835-30)” ~~which clarifies the~~clarifying that debt issuance costs related to line-of-credit arrangements ~~stating that they~~ could be presented as an asset and amortized over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. ~~For us,~~We adopted this ASU in the ~~standard is effective for financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within those years. This~~first quarter of 2016. Adoption of this ASU ~~is expected to~~did not have noa material impact on our financial position and results of operations.

In May 2014, the FASB issued ~~Accounting Standard Update (“ASU”)~~ASU 2014-09,“Revenue from Contracts with Customers (Topic 606),” which will replace numerous requirements in U.S. GAAP, including industry-specific requirements, and provide companies with a single revenue recognition model for recognizing revenue from contracts with customers. The core principle of the new standard is that a company should recognize revenue to show the transfer of promised goods or services to customers in an amount that reflects the

consideration to which the company expects to be entitled to in exchange for those goods or services. ~~On April 1,~~In August 2015, ~~the~~ FASB ~~proposed a deferral of~~issued ASU 2015-14, which deferred the effective date of the new revenue standard by one ~~year, until January 1, 2018. This deferral was approved on July 22, 2015. The~~year. For Teradyne, the standard will be effective in ~~our~~the first quarter of 2018. Early adoption is permitted but not before the original effective date (that is, annual periods beginning after December 15, 2016). The two permitted transition methods under the new standard are the full retrospective method, in which case the standard would be applied to each prior reporting period presented, or the modified retrospective method, in which case the cumulative effect of applying the standard would be recognized at the date of initial application. We have not yet selected a transition method. We are currently evaluating the impact of this ASU on our financial position and results of operations.

For “Quantitative and Qualitative Disclosures about Market Risk” affecting Teradyne, see Part 2 Item 7a, “Quantitative and Qualitative Disclosures about Market Risks,” in our Annual Report on Form 10-K filed with the SEC on February ~~27, 2015.~~29, 2016. 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, ~~2014.~~2015.

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.

We are 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 our results of operations, financial condition or cash flows.

In addition to other information set forth in this Form 10-Q, 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, ~~2014,~~2015, which could materially affect our business, financial condition or future results. The risk factors described in our Annual Report on Form 10-K remain applicable to our business.

The risks described in our Annual Report on Form 10-K 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.

~~We may incur indebtedness.~~The recent natural disaster in Japan could disrupt our operations and adversely affect our results of operations.

On April 27, 2015, we entered into a five-year, senior secured revolving credit facility of $350.0 million. Subject to customary conditions, we may seek to obtain from existing or new lenders incremental commitments underThe recent earthquake in Japan has damaged our building and impacted our operations located in Kumamoto. We are temporarily transferring the credit facility in an aggregate principal amount not to exceed $150.0 million. We have not borrowed any funds under this credit facility. We could borrow funds under this credit facility at any time for general corporate purposes and working capital. Incurring indebtedness, among other things, could:

~~Restrictive covenants in the agreement governing our senior secured revolving credit facility may restrict~~have a significant impact on our ability to ~~pursue~~manufacture our products or sell products to our customers. However, the situation in Kumamoto remains uncertain so the events could have a short-term impact to our business ~~strategies.~~

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

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

In June 2015, we acquired Universal Robots. We may not be able to realize the benefit of acquiring Universal Robots or successfully grow Universal Robots’ 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~~have to incur significant costs in order to repair our ~~acquisitions may be complex, costly~~building which could have an adverse effect on our financial condition and ~~time consuming and include unanticipated issues, expenses and liabilities. We may have difficulty in developing, manufacturing and marketing the products~~results 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, incurring debt, issuing shares of our common stock, or by other means.operations.

In January 2015, our Board of Directors ~~cancelled our 2010 stock repurchase program and~~ authorized a ~~new~~ stock repurchase program for up to $500 million of common stock, of which $300 million ~~of which~~was repurchased in 2015. In 2016, we intend to repurchase ~~in 2015.~~between $100 million and $200 million. The cumulative repurchases as of ~~October 4, 2015~~April 3, 2016 totaled ~~11.9~~17.1 million shares of common stock for ~~$226.8~~$328 million at an average price per share of ~~$19.09.~~$19.17.

The following table includes information with respect to repurchases we made of our common stock during the three months ended ~~October 4, 2015~~April 3, 2016 (in thousands except per share price):

We satisfy U.S. federal and state minimum withholding tax obligations due upon the vesting and the conversion of restricted stock units into shares of our common stock, by automatically withholding from the shares being issued, a number of shares with an aggregate fair market value on the date of such vesting and conversion that would satisfy the minimum withholding amount due.
