B. ACCOUNTING POLICIES

Basis of Presentation

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 statement of such interim financial statements. Certain prior year amounts were reclassified to conform to the current year presentation. The December 31, 2016 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 March 1, 2017, for the year ended December 31, 2016.

Preparation of Financial Statements and Use of Estimates

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

Stock-Based Compensation

In March 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-09, “Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting.” Teradyne adopted this ASU in the first quarter of 2017. This ASU changes how Teradyne accounts 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 statements of cash flows.

Adoption of this ASU required recognition of a cumulative effect adjustment to retained earnings for any prior year excess tax benefits or tax deficiencies not previously recorded. The cumulative effect adjustment of $39 million was recorded as an increase to retained earnings and deferred tax assets.

This ASU also required a change in how Teradyne recognizes the excess tax benefits or tax deficiencies related to stock-based compensation. Prior to adopting ASU 2016-09, these excess tax benefits or tax deficiencies were credited or charged to additional paid-in capital in Teradyne’s consolidated balance sheets. In accordance with ASU 2016-09, starting in the first quarter of 2017, these excess tax benefits or tax deficiencies are recognized as a discrete tax benefit or discrete tax expense to the current income tax provision in Teradyne’s consolidated statements of operations.

ASU 2016-09 requires companies to adopt the amendment related to accounting for excess tax benefits or tax deficiencies on a prospective basis. For the three and nine months ended October 1, 2017, Teradyne recognized a discrete tax benefit of $0.0 and $6.0 million, respectively, related to net excess tax benefit.

In addition, under ASU 2016-09, all excess tax benefits related to share-based payments are reported as cash flows from operating activities. Previously, excess tax benefits from share-based payments arrangements were reported as cash flows from financing activities. The classification amendment was applied prospectively. This ASU also clarifies that all cash payments made to taxing authorities on the employees’ behalf for withheld shares should be presented as financing activities on the statement of cash flows. Previously, Teradyne reported cash payments made to taxing authorities as operating activities on the statement of cash flows. This change was applied retrospectively.

Upon adoption of ASU 2016-09, Teradyne made an accounting policy election to continue accounting for forfeitures by applying an estimated forfeiture rate.

Contingencies and Litigation

Teradyne may be subject to certain legal proceedings, lawsuits and other claims as discussed in Note P. Teradyne accrues for a loss contingency, including legal proceedings, lawsuits, pending claims and other legal matters, when the likelihood of a loss is probable and the amount of the loss can be reasonably estimated. When the reasonable estimate of the loss is within a range of amounts, and no amount in the range constitutes a better estimate than any other amount, Teradyne accrues the amount at the low end of the range. Teradyne adjusts the accruals from time to time as additional information is received, but the loss incurred may be significantly greater than or less than the amount accrued. Loss contingencies are disclosed when they are material and there is at least a reasonable possibility that a loss has been incurred. Attorney fees related to legal matters are expensed as incurred.

C. RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

On March 10, 2017, the FASB issued ASU 2017-07, “Compensation—Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost.” This ASU provides guidance on presentation of net periodic pension cost and net periodic postretirement benefit cost. The new standard requires the service cost component to be presented in the same line item as other employee compensation costs arising from services rendered during the period. The other components of net benefit cost such as interest cost, amortization of prior service cost, and actuarial gains or losses, are required to be presented separately outside of income or loss from operations. The presentation of service cost should be applied retrospectively. The guidance is effective for fiscal years beginning after December 15, 2017. Early adoption is permitted. This guidance will impact the presentation of Teradyne’s consolidated financial statements. Upon adoption of the new standard, Teradyne will present interest cost, amortization of prior service cost, and actuarial gains or losses within other (income) expense, net.

On January 26, 2017, the FASB issued ASU 2017-04, “Intangibles—Goodwill and Other (Topic 350): Simplifying the Accounting for Goodwill Impairment.” The new guidance removes Step 2 of the goodwill impairment test, which requires a hypothetical purchase price allocation. Goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. All other goodwill impairment guidance will remain largely unchanged. Entities will continue to have the option to perform a qualitative assessment to determine if a quantitative impairment test is necessary. The same one-step impairment test will be applied to goodwill at all reporting units, even those with zero or negative carrying amounts. Entities will be required to disclose the amount of goodwill at reporting units with zero or negative carrying amounts. The revised guidance will be applied prospectively, and is effective in 2020. Early adoption is permitted for any impairment tests performed after January 1, 2017. Teradyne is currently evaluating the impact of this ASU on its financial position, results of operations and statements of cash flows.

In October 2016, the FASB issued ASU 2016-16, “Accounting for Income Taxes: Intra-Entity Asset Transfers of Assets Other than Inventory.” Under current Generally Accepted Accounting Principles (“GAAP”), the tax effects of intra-entity asset transfers are deferred until the transferred asset is sold to a third party or otherwise recovered through use. The new guidance requires recognition of the tax expense from the sale of the asset in the seller’s tax jurisdiction when the transfer occurs, even though the pre-tax effects of that transaction are eliminated in consolidation. Any deferred tax asset that arises in the buyer’s jurisdiction would also be recognized at the time of the transfer. The new guidance does not apply to intra-entity transfers of inventory. The income tax consequences from the sale of inventory from one member of a consolidated entity to another will continue to be deferred until the inventory is sold to a third party. The new guidance will be effective in fiscal years beginning after December 15, 2017. Early adoption is permitted. The modified retrospective approach will be required for transition to the new guidance, with a cumulative-effect adjustment recorded in retained earnings as of the beginning of the period of adoption. Teradyne does not expect this ASU to have a material impact on its financial position, results of operations and statements of cash flows.

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 an 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 statements of operations. The new standard is effective for annual periods beginning after December 15, 2018 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 January 2016, the FASB issued 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 beginning after December 15, 2017. Teradyne is currently evaluating the impact of this ASU on its financial position and results of operations.

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 one year. For Teradyne, the standard will be effective in the first quarter of 2018. 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 selected the modified retrospective transition method.

Teradyne has completed its preliminary assessment of the financial statement impact of the new standard and does not expect this ASU to have a material impact on its financial position or results of operations. This preliminary assessment is based on a review of the types and number of revenue arrangements currently in place including the review of individual customer contracts related to these revenue streams. The exact impact of the new standard will be dependent on facts and circumstances at adoption and could vary from quarter to quarter. Based on Teradyne’s preliminary assessment Teradyne does not expect any major changes to be made to existing accounting systems or internal controls. Teradyne will be required to record cumulative effect adjustments to retained earnings upon adopting the new standard in the first quarter of 2018.

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

Marketable Securities

Teradyne accounts for its investments in debt and equity securities in accordance with the provisions of ASC 320-10, “Investments—Debt and Equity Securities.” ASC 320-10 requires that certain debt and equity securities be classified into one of three categories: trading, available-for-sale or held-to-maturity securities. As of October 1, 2017, 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:

•

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

•

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

•

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

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 1, 2017 and October 2, 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;

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; 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 debt and equity securities are classified as Level 1 and Level 2. Acquisition-related contingent consideration is classified as Level 3. Teradyne determines the fair value of acquisition-related contingent consideration using a Monte Carlo simulation model. Assumptions utilized in the model include forecasted revenues, revenue volatility and discount rate. 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 and nine months ended October 1, 2017 were $0.2 million and $0.7 million, respectively. Realized losses recorded in the three and nine months ended October 1, 2017 were $0.0 million and $0.3 million, respectively. Realized gains in the three and nine months ended October 2, 2016 were $0.7 million and $1.2 million, respectively. Realized losses recorded in the three and nine months ended October 2, 2016 were $0.1 million and $0.4 million, respectively. 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 three and nine months ended October 1, 2017 and October 2, 2016, 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 1, 2017 and December 31, 2016.

(a)

In the nine months ended October 1, 2017, Teradyne paid $1.1 million of contingent consideration for the earn-out in connection with the acquisition of Avionics Interface Technology, LLC (“AIT”). In the nine months ended October 2, 2016, based on Universal Robots’ calendar year 2015 EBITDA results, Teradyne paid $15.0 million or 100% of the eligible EBITDA contingent consideration amount in connection with the acquisition of Universal Robots.

(b)

In the nine months ended October 1, 2017, the fair value of contingent consideration for the earn-out in connection with the acquisition of Universal Robots was increased by $1.8 million due to an increase in forecasted revenue. In the three and nine months ended October 2, 2016, the fair value of contingent consideration for the earn-out in connection with the acquisition of Universal Robots was increased by $8.0 million and $9.9 million, respectively, primarily due to an increase in forecasted revenue and a decrease in the discount rate.

(c)	In the nine months ended October 2, 2016, the fair value of contingent consideration for the earn-out in connection with the acquisition of AIT was increased by $0.6 million due to an increase in forecasted revenue.

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


Liability	October 1, 2017 Fair Value		Valuation Technique		Unobservable Inputs	Weighted Average
	(in thousands)
Contingent consideration (Universal Robots)		$21,818		Monte Carlo Simulation	Revenue for the period July 1, 2015—December 31, 2017 volatility		11.5	%
		$21,818		Monte Carlo Simulation	Discount rate		2.6	%


		$17,311		Monte Carlo Simulation	Revenue for the period July 1, 2015—December 31, 2018 volatility		11.5	%
					Discount rate		2.6	%

As of October 1, 2017, the significant unobservable inputs used in the Monte Carlo simulation to fair value the Universal Robots contingent consideration include forecasted revenue, revenue volatility and discount rate. Increases or decreases in the inputs would result in a higher or lower fair value measurement. The maximum payment for each of the two Universal Robots revenue earn-outs is $25.0 million.

The carrying amounts and fair values of Teradyne’s financial instruments at October 1, 2017 and December 31, 2016 were as follows:

Derivatives

Teradyne conducts business in a number of foreign countries, with certain transactions denominated in local currencies. The purpose of Teradyne’s foreign currency management is to minimize the effect of exchange rate fluctuations on certain foreign currency denominated 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 at October 1, 2017 and December 31, 2016 was $79.2 million and $83.9 million, respectively.

The following table summarizes the fair value of derivative instruments at October 1, 2017 and December 31, 2016:

F. DEBT

Convertible Senior Notes

On December 12, 2016, Teradyne completed a private offering of $460.0 million convertible senior unsecured notes (the “Notes”). The Notes will mature on December 15, 2023, unless earlier repurchased or

converted. The Notes bear interest from December 12, 2016 at a rate of 1.25% per year payable semi-annually in arrears on June 15 and December 15 of each year, beginning on June 15, 2017.

The Notes will be convertible at the option of the noteholders at any time prior to the close of business on the business day immediately preceding September 15, 2023, under the following circumstances: (1) during any calendar quarter beginning after March 31, 2017 (and only during such calendar quarter), if the closing sale price of Teradyne’s common stock, for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter is greater than 130% of the conversion price on each applicable trading day; (2) during the five business day period after any five consecutive trading day period (the “measurement period”) in which the trading price (as defined in the Indenture) per $1,000 principal amount of Notes for each trading day of the measurement period was less than 98% of the product of the closing sale price of the Teradyne’s common stock and the conversion rate on each such trading day; and (3) upon the occurrence of specified corporate events. On or after September 15, 2023 until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert their Notes at any time, regardless of the foregoing circumstances. Teradyne may satisfy its conversion obligation by paying or delivering cash, shares of its common stock or a combination of cash and shares of its common stock, at Teradyne’s election. The conversion rate for the Notes will initially be 31.4102 shares per $1,000 principal amount, which is equivalent to an initial conversion price of approximately $31.84 per share of Teradyne’s common stock. The conversion rate is subject to adjustment under certain circumstances.

Concurrent with the offering of the Notes, Teradyne entered into convertible note hedge transactions (the “Note Hedge Transactions”) with the initial purchasers or their affiliates (the “Option Counterparties”). The Note Hedge Transactions cover, subject to customary anti-dilution adjustments, the number of shares of the common stock that underlie the Notes, with a strike price equal to the initial conversion price of the Notes of $31.84. The Note Hedge Transactions cover, subject to customary anti-dilution adjustments, approximately 14.4 million shares of Teradyne’s common stock.

The convertible note hedge is considered indexed to Teradyne’s stock as the terms of the Note Hedge Transactions do not contain an exercise contingency and the settlement amount equals the difference between the fair value of a fixed number of Teradyne’s shares and a fixed strike price. Because the only variable that can affect the settlement amount is Teradyne’s stock price, which is an input to the fair value of a fixed-for-fixed option contract, the convertible note hedge is considered indexed to Teradyne’s stock.

Separately and concurrent with the pricing of the Notes, Teradyne entered into warrant transactions with the Option Counterparties (the “Warrant Transactions”) in which it sold net-share-settled (or, at its election subject to certain conditions, cash-settled) warrants to the Option Counterparties. The Warrant Transactions cover, subject to customary anti-dilution adjustments, approximately 14.4 million shares of common stock. The strike price of the warrants will initially be $39.95 per share (subject to adjustment). The Warrant Transactions could have a dilutive effect to Teradyne’s common stock to the extent that the market price per share of Teradyne’s common stock, as measured under the terms of the Warrant Transactions, exceeds the applicable strike price of the warrants.

The Note Hedge Transactions are expected to reduce the potential dilution to Teradyne’s common stock upon any conversion of the Notes. However, the Warrant Transactions could separately have a dilutive effect to the extent that the market value per share of Teradyne’s common stock exceeds the applicable strike price of the warrant.

In connection with establishing their initial hedge of these convertible note hedge and warrant transactions, the Option Counterparties have entered into various derivative transactions with respect to Teradyne’s common stock and/or purchased shares of Teradyne’s common stock or other securities, including the Notes, concurrent with, or shortly after, the pricing of the Notes. In addition, the Option Counterparties may modify their hedge

positions by entering into or unwinding various derivative transactions with respect to Teradyne’s common stock or by selling Teradyne’s common stock or other securities, including the Notes, in secondary market transactions (and may do so during any observation period related to the conversion of the Notes). These activities could adversely affect the value of Teradyne’s common stock and the Notes.

Teradyne’s effective annual interest rate on the Notes is 5.0%. At October 1, 2017 and December 31, 2016, the Notes are classified as long-term debt in the balance sheets based on their December 15, 2023 maturity date. Debt issuance costs of approximately $7.2 million are being amortized to interest expense over the seven-year term of the Notes. As of October 1, 2017, unamortized debt issuance costs were $6.5 million.

The below tables represent the key components of Teradyne’s convertible senior notes:


	October 1, 2017		December 31, 2016
	(in thousands)
Debt principal	$	460,000	$	460,000

Amortization of the discount component and debt issue fees recognized as interest expense		3,350		9,926

Total interest expense on the convertible debt	$	4,772	$	14,223

As of October 1, 2017, the remaining unamortized discount was $97.4 million, which will be amortized over 6.3 years using the effective interest rate method. The carrying amount of the equity component was $100.8 million. As of October 1, 2017, the conversion rate was equal to the initial conversion price of approximately $31.84 per share and the if-converted value of the Notes was $538.7 million.

Revolving Credit Facility

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 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 statements of operations. As of November 9, 2017, 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 November 9, 2017, 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.

J. STOCK-BASED COMPENSATION

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”).

Stock options to purchase Teradyne’s common stock at 100% of the fair market value on the grant date vest in equal annual installments over four years from the grant date and have a maximum term of seven years.

Time-based restricted stock unit awards granted to employees vest in equal annual installments over four years. Restricted stock unit awards granted to non-employee directors vest after a one year period, with 100% of the award vesting on the first anniversary of the grant date. Teradyne expenses the cost of the restricted stock unit awards subject to time-based vesting, which is determined to be the fair market value of the shares at the date of grant, ratably over the period during which the restrictions lapse.

Commencing in January 2014, Teradyne granted 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 2016 and 2017, Teradyne’s three-year TSR performance is measured against the 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% 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 2017 and 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”) as a percent of Teradyne’s revenue. 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; non-cash convertible debt interest expense; 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 PRSUs will vest if the executive officer is no longer an employee at the end of the three-year period.

During the nine months ended October 1, 2017 and October 2, 2016, Teradyne granted 0.1 million TSR PRSUs with a grant date fair value of $35.66 and $20.29, respectively. The fair value was estimated using the Monte Carlo simulation model with the following assumptions:


	For the Nine Months Ended
	October 1, 2017			October 2, 2016
Risk-free interest rate		1.5	%		1.0	%
Teradyne volatility-historical		26.6	%		27.0	%
NYSE Composite Index volatility-historical		13.4	%		13.1	%
Dividend yield		1.0	%		1.2	%

Expected volatility was based on the historical volatility of Teradyne’s stock and the NYSE Composite Index for the 2017 and 2016 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 $0.28 per share for 2017 grants and $0.24 per share for 2016 grants, divided by Teradyne’s stock price on the grant date of $28.56 for the 2017 grant and $19.43 for the 2016 grant.

During the nine months ended October 1, 2017, Teradyne granted 0.1 million of PBIT PRSUs with a grant date fair value of $27.72.

During the nine months ended October 1, 2017, Teradyne granted 0.8 million of service-based restricted stock unit awards to employees at a weighted average grant date fair value of $28.03, 0.1 million of service-based restricted stock unit awards to non-employee directors at a weighted average grant date fair value of $34.48, and 0.1 million of service-based stock options to executive officers at a weighted average grant date fair value of $7.13.

During the nine months ended October 2, 2016, Teradyne granted 0.1 million PBIT PRSUs with a grant date fair value of $18.71.

During the nine months ended October 2, 2016, Teradyne granted 1.2 million of service-based restricted stock unit awards to employees at a weighted average grant date fair value of $18.49, 0.1 million of service-based restricted stock unit awards to non-employee directors at a weighted average grant date fair value of $18.71 and 0.1 million of service-based stock options to executive officers at a weighted average grant date fair value of $5.30.

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
	October 1, 2017			October 2, 2016
Expected life (years)		5.0			5.0
Risk-free interest rate		2.0	%		1.4	%
Volatility-historical		27.8	%		32.9	%
Dividend yield		1.0	%		1.2	%

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 $0.28 per share for 2017 grants and $0.24 per share for 2016 grants, divided by Teradyne’s stock price on the grant date of $28.56 for the 2017 grant and $19.43 for the 2016 grant.

L. GOODWILL AND ACQUIRED INTANGIBLE ASSETS

Goodwill

Teradyne performs its annual goodwill impairment test as required under the provisions of ASC 350-10, “Intangibles—Goodwill and Other” on December 31 of each fiscal year unless interim indicators of impairment exist. Goodwill is considered impaired when the net book value of a reporting unit exceeds its estimated fair value.

In the second quarter of 2016, the Wireless Test reporting unit (which is Teradyne’s Wireless Test operating and reportable segment) reduced headcount by 11% as a result of a sharp decline in projected demand attributable to an estimated smaller future wireless test market. The decrease in projected demand was due to

lower forecasted buying from Teradyne’s largest Wireless Test segment customer (who had previously contributed between 51% and 73% of annual Wireless Test sales since the LitePoint acquisition in 2011) as a result of the customer’s numerous operational efficiencies; slower smartphone growth rates; and a slowdown of new wireless technology adoption. Teradyne considered the headcount reduction and sharp decline in projected demand to be a triggering event for an interim goodwill impairment test.

Teradyne used the income and market approaches to determine the fair value of the Wireless Test reporting unit for step 1 of the goodwill impairment test. With respect to the income approach, Teradyne used the discounted cash flow method, which included seven year future cash flow projections and an estimated terminal value. The cash flow projections were prepared using Teradyne’s forecast, which was based upon underlying estimates of the total market size, and Teradyne’s market share in the wireless test market developed using Teradyne and independent third party data. The estimated terminal value was calculated using the Gordon Growth model. The market approach used a revenue multiple to develop an estimate of fair value. The revenue multiple was estimated using enterprise value as a ratio of next twelve months revenue for comparable companies. Teradyne equally weighted the income and market approaches to determine the fair value of the Wireless Test reporting unit. The carrying amount of the Wireless Test reporting unit exceeded its fair value; therefore, the second step of the goodwill impairment test was performed to calculate implied goodwill and to measure the amount of the impairment loss.

Teradyne allocated the fair value of the Wireless Test reporting unit to all of its assets and liabilities (including unrecognized intangible assets). The net book value of raw materials inventory was estimated as an approximation of current replacement costs. The fair value of finished goods inventory was estimated at the present value of selling price less direct selling costs and profit on the selling effort. The selling price used in the inventory fair values was based upon the product gross margins included in Teradyne’s forecast. The fair value of the deferred revenue liability was estimated by assessing the costs required to service the obligation plus a reasonable profit margin. The fair value for personal property assets, which consisted of furniture and fixtures, machinery and equipment, computer equipment, software and leasehold improvements, was estimated using the replacement cost approach, which approximated carrying value. The fair value of intangible assets was estimated using the income approach and, in particular, developed technology and trademarks/trade names were valued using the relief-from-royalty method and customer relationships and customer backlog were valued using the discounted cash flow method. Royalty rates were estimated using rates applicable to wireless testing equipment and other similar technologies. Based upon this allocation, Teradyne determined that goodwill was valued at $8.0 million and recorded an impairment loss of $254.9 million in the second quarter of 2016.

The changes in the carrying amount of goodwill by reportable segments for the nine months ended October 1, 2017, were as follows:


	Industrial Automation		System Test			Wireless Test			Semiconductor Test			Total
	(in thousands)
Balance at December 31, 2016
Goodwill	$	204,851	$	158,699		$	361,819		$	260,540		$	985,909

	$	230,785	$	10,516		$	7,976		$	—		$	249,277

Acquired Intangible Assets

Teradyne reviews long-lived assets for impairment whenever events or changes in business circumstances indicate that the carrying amount of the assets may not be fully recoverable or that the useful lives of these assets are no longer appropriate. As a result of the Wireless Test segment goodwill impairment review in the second quarter of 2016, Teradyne performed an impairment test of the Wireless Test segment’s intangible and long-lived assets. The impairment test is based on a comparison of the estimated undiscounted cash flows to the carrying value of the asset group. If undiscounted cash flows for the asset group are less than the carrying amount, the asset group is written down to its estimated fair value based on a discounted cash flow analysis. The cash flow estimates used to determine the impairment contain management’s best estimates using appropriate assumptions and projections at that time. The fair value of intangible assets was estimated using the income approach and, in particular, developed technology and trademarks/trade names were valued using the relief-from-royalty method and customer relationships were valued using the discounted cash flow method. Royalty rates were estimated using rates applicable to wireless testing equipment and other similar technologies. As a result of the analysis, Teradyne recorded an $83.3 million impairment charge in the second quarter of 2016 in acquired intangible assets impairment on the statements of operations.

Amortizable acquired intangible assets consist of the following and are included in acquired intangible assets, net on the balance sheet:

Net income (loss) per common share-basic	$	0.52	$	0.32	$	1.83	$	(0.54	)

Net income (loss) per common share-diluted	$	0.52	$	0.31	$	1.81	$	(0.54	)

(1)

Incremental shares from assumed conversion of the convertible notes for the three and nine months ended October 1, 2017 are calculated using the difference between the average Teradyne stock price for the period and the conversion price of $31.84, multiplied by the 14.4 million shares that would be issued upon conversion. The result of this calculation, representing the total intrinsic value of the convertible debt, is divided by the average Teradyne stock price for the period.

The computation of diluted net income per common share for the three and nine months ended October 1, 2017 excludes the effect of the potential exercise of stock options to purchase approximately 0.1 million shares because the effect would have been anti-dilutive.

The computation of diluted net income per common share for the three months ended October 2, 2016 excludes the effect of the potential exercise of stock options to purchase approximately 0.1 million shares because the effect would have been anti-dilutive.

The computation of diluted net income per common share for the nine months ended October 2, 2016 excludes the effect of the potential exercise of all outstanding stock options and restricted stock units because Teradyne had a net loss and inclusion would be anti-dilutive.

N. RESTRUCTURING AND OTHER

During the three months ended October 1, 2017, Teradyne recorded $5.1 million of property insurance recovery related to the Japan earthquake, a $0.4 million credit related to a previously impaired lease termination of a Wireless Test facility in Sunnyvale, CA, and a $0.3 million credit for the decrease in the fair value of the Universal Robots contingent consideration liability, partially offset by $0.8 million of Japan earthquake related expenses and $0.6 million recorded for employee severance charges, primarily in Semiconductor Test.

During the three months ended October 2, 2016, Teradyne recorded $8.0 million for the increase in the fair value of the Universal Robots contingent consideration liability and $4.2 million for employee severance charges, primarily in Semiconductor Test and Wireless Test.

During the nine months ended October 1, 2017, Teradyne recorded $2.0 million for employee severance charges, primarily in Industrial Automation and Corporate, $1.8 million for the increase in the fair value of the Universal Robots contingent consideration liability, $0.9 million for a lease impairment of a Wireless Test facility in Sunnyvale, CA, which was terminated in September 2017, and $0.8 million of Japan earthquake related expenses, partially offset by $5.1 million of property insurance recovery related to the Japan earthquake.

During the nine months ended October 2, 2016, Teradyne recorded $10.5 million for the increase in the fair value of contingent consideration liability, of which $9.9 million was related to Universal Robots and $0.6 million was related to AIT, $5.9 million for employee severance charges, primarily in Semiconductor Test and Wireless Test, $4.2 million for an impairment of fixed assets, and $0.9 million for Japan earthquake related expenses, partially offset by $5.1 million of property insurance recovery related to the Japan earthquake.

O. RETIREMENT PLANS

ASC 715, “Compensation—Retirement Benefits” requires an employer with defined benefit plan or other postretirement benefit plan to recognize an asset or a liability on its balance sheet for the overfunded or underfunded status of the plan. The pension asset or liability represents a difference between the fair value of the pension plan’s assets and the projected benefit obligation.

Defined Benefit Pension Plans

Teradyne has defined benefit pension plans covering a portion of domestic employees and employees of certain non-U.S. subsidiaries. Benefits under these plans are based on employees’ years of service and compensation. Teradyne’s funding policy is to make contributions to these plans in accordance with local laws and to the extent that such contributions are tax deductible. The assets of the U.S. qualified pension plan consist primarily of fixed income and equity securities. In addition, Teradyne has unfunded qualified foreign plans as well as 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”).

In the nine months ended October 1, 2017, Teradyne contributed $1.9 million to the U.S. qualified pension plan, $1.9 million to the U.S. supplemental executive defined benefit pension plan and $0.6 million to certain qualified pension plans for non-U.S. subsidiaries.

In the nine months ended October 2, 2016, Teradyne contributed $1.9 million to the U.S. qualified pension plan, $1.9 million to the U.S. supplemental executive defined benefit pension plan and $1.5 million to certain qualified pension plans for non-U.S. subsidiaries.

For the three and nine months ended October 1, 2017 and October 2, 2016, Teradyne’s net periodic pension cost (income) was comprised of the following:

P. COMMITMENTS AND CONTINGENCIES

Purchase Commitments

As of October 1, 2017, Teradyne had entered into purchase commitments for certain components and materials. The purchase commitments covered by the agreements aggregate to approximately $234.2 million, of which $226.3 million is for less than one year.

Legal Claims

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

Q. INCOME TAXES

The effective tax rate for the three months ended October 1, 2017 and October 2, 2016 was 18.8% and (6.9%), respectively. The effective tax rate for the nine months ended October 1, 2017 and October 2, 2016 was 14.7% and 3.7%, respectively.

The increase in the effective tax rate from the three and nine months ended October 2, 2016 to the three and nine months ended October 1, 2017 is primarily attributable to a shift in the geographic distribution of income which increased income subject to taxation in the U.S. relative to lower tax rate jurisdictions, the effect of a U.S. non-deductible goodwill impairment charge and decreases in discrete tax benefits.

The effective tax rates for the three and nine months ended October 1, 2017 differed from the expected federal statutory rate of 35% primarily because of the favorable effect of statutory rates applicable to income earned outside the U.S. The tax rates for the three and nine months ended October 1, 2017 were 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.

Discrete tax items recorded in the three and nine months ended October 1, 2017 amounted to expense of $0.3 million and benefit of $6.1 million, respectively. The $0.3 million of discrete tax expense recorded in the three months ended October 1, 2017 was primarily composed of $0.8 million of expense related to non-taxable foreign exchange loss, $0.2 million of benefit from reductions in tax reserves and $0.2 million of benefit from stock based compensation. The $6.1 million of discrete tax benefit recorded in the nine months ended October 1, 2017 was primarily composed of $6.7 million of benefit from stock-based compensation, $1.0 million of expense related to actuarial gains, $0.7 million of benefit related to U.S. research and development tax credits, $0.5 million of benefit from reductions in tax reserves and $1.1 million of expense related to non-taxable foreign exchange loss.

The effective tax rates for the three and nine months ended October 2, 2016 differed from the expected federal statutory rate of 35% as a result of a non-deductible goodwill impairment charge, which reduced the benefit of the U.S. loss before income taxes, and increases in uncertain tax positions for transfer pricing, offset by the effect of lower statutory rates applicable to income earned outside the U.S. and the benefit of U.S. research and development tax credits, all of which were included in the projected annual effective tax rate.

Discrete tax benefits recorded in the three and nine months ended October 2, 2016 amounted to $6.4 million and $13.3 million respectively. The $6.4 million of discrete tax benefits recorded in the three months ended October 2, 2016 included $3.1 million from out-of-period adjustments, $1.6 million related to tax credit carryforwards, $0.7 million from non-taxable foreign exchange gains and $1.0 million of benefit from other discrete tax items. The $13.3 million of discrete tax benefits recorded in the nine months ended October 2, 2016 included $4.1 million from non-taxable foreign exchange gains, $3.1 million from out-of-period adjustments,

$2.6 million of tax reserve releases resulting from the settlement of a U.S. tax audit, $1.6 million related to tax credit carryforwards, $0.9 million related to marketable securities and $1.0 million of benefit from other discrete tax items.

During the three and nine months ended October 2, 2016, Teradyne recorded out-of-period adjustments of approximately $3.1 million to increase deferred tax assets and decrease income tax expense related to alternative minimum tax credits and capitalized inventory costs that should have been recognized previously. The out-of-period adjustments were not material to the relevant prior periods.

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 1, 2017, Teradyne believes that it will ultimately realize the deferred tax assets recorded on the condensed consolidated balance sheets. 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 1, 2017 and December 31, 2016, Teradyne had $44.2 million and $39.0 million, respectively, of reserves for uncertain tax positions. The $5.2 million net increase in reserves for uncertain tax positions is primarily composed of additions related to transfer pricing exposures and tax credits.

As of October 1, 2017, Teradyne estimates that there will be no material change in the balance of uncertain tax positions in the next twelve months.

Teradyne recognizes interest and penalties related to income tax matters in income tax expense. As of October 1, 2017 and December 31, 2016, $0.4 million and $0.4 million, respectively, of interest and penalties were accrued for uncertain tax positions. For the nine months ended October 1, 2017, a benefit of $0.1 million was recorded for interest and penalties related to income tax items. For the nine months ended October 2, 2016, an expense of $0.3 million was recorded for interest and penalties related to income tax items.

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 months ended October 1, 2017 was $20.5 million, or $0.10 per diluted share. The tax savings due to the tax holiday for the nine months ended October 2, 2016 was $25.2 million, or $0.12 per diluted share. The tax holiday is scheduled to expire on December 31, 2020.

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

Statements in this Quarterly Report on Form 10-Q which are not historical facts, so called “forward-looking statements,” are made pursuant to the safe harbor provisions of Section 21E of the Securities Exchange Act of 1934, as amended. Investors are cautioned that all forward-looking statements involve risks and uncertainties, including those detailed in 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, 2016. Readers are cautioned not to place undue reliance on these forward-looking statements which reflect management’s analysis only as of the date hereof. We assume no obligation to update these forward-looking statements to reflect actual results or changes in factors or assumptions affecting forward-looking statements, except as may be required by law.

Overview

We are a leading global supplier of automation equipment for test and industrial applications. We design, develop, manufacture and sell 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. 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:

•

semiconductor test (“Semiconductor Test”) systems;

•

industrial automation (“Industrial Automation”) products; and

•

wireless test (“Wireless Test”) systems.

We have a customer base which includes integrated device manufacturers (“IDMs”), outsourced semiconductor assembly and test providers (“OSATs”), original equipment manufacturers (“OEMs”), 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.

The market for our test products is concentrated with a limited number of significant customers accounting for a substantial portion of the purchases of test equipment. One customer drives significant demand for our products both through direct sales and sales to the customer’s supply partners. We expect that sales of our test products will continue to be concentrated with a limited number of significant customers for the foreseeable future.

In 2015, we acquired Universal Robots A/S (“Universal Robots”), 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, increase manufacturing efficiency and decrease manufacturing costs. 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. The total purchase price for Universal Robots was approximately $315 million, which included cash paid of approximately $284 million and $32 million in fair value of contingent consideration payable upon achievement of revenue and earnings targets through 2018. Contingent consideration paid for 2015 was $15 million. The remaining maximum contingent consideration that could be paid is $50 million.

We believe our recent acquisition has 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 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 have generally affected the semiconductor and electronics test equipment and services industries more significantly than the overall capital equipment sector.

For several years, this cyclical demand became an even/odd year trend where demand increased in even years and decreased in odd years due principally to demand swings in the mobility market of our Semiconductor Test business. We expect the even/odd year demand trend in the mobility market to lessen in 2017 and future years due to slower smart phone unit growth, along with rising device complexity and the reduced impact of parallel test in our Semiconductor Test business.

In the second quarter of 2016, the Wireless Test reporting unit (which is our Wireless Test operating and reportable segment) reduced headcount by 11% as a result of a sharp decline in projected demand attributable to an estimated smaller future wireless test market. The decrease in projected demand was due to lower forecasted buying from our largest Wireless Test segment customer (who had previously contributed between 51% and 73% of annual Wireless Test sales since the LitePoint acquisition in 2011) as a result of the customer’s numerous operational efficiencies; slower smartphone growth rates; and a slowdown of new wireless technology adoption. We considered the headcount reduction and sharp decline in projected demand to be a triggering event for an interim goodwill impairment test. Following the interim goodwill impairment test, we recorded a goodwill impairment charge of $254.9 million, with approximately $8.0 million of goodwill remaining, and $83.3 million for the impairment of acquired intangible assets with approximately $4.0 million of acquired intangible assets remaining.

Critical Accounting Policies and Estimates

We have identified the policies which are critical to understanding our business and our results of operations. There have been no significant changes during the three and nine months ended October 1, 2017 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, 2016.

	October 1, 2017			October 2, 2016			Dollar/ Point Change
	(in millions)
Gross profit	$	294.8		$	227.4		$	67.4
Percent of total revenues		58.6	%		55.4	%		3.2

Gross profit as a percent of revenue increased by 3.2 points, as a result of a 1.9 point increase related to favorable product mix in Semiconductor Test and 1.3 points due to higher sales primarily in Semiconductor Test and Industrial Automation.

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 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 1, 2017, we recorded an inventory provision of $1.9 million included in cost of revenues primarily due to downward revisions to previously forecasted demand levels for certain products. Of the $1.9 million of total excess and obsolete provisions, $0.7 million was related to Semiconductor Test, $0.7 million was related to Wireless Test, $0.3 million was related to System Test, and $0.1 million was related to Industrial Automation.

During the three months ended October 2, 2016, we recorded an inventory provision of $3.0 million included in cost of revenues primarily due to downward revisions to previously forecasted demand levels for certain products. Of the $3.0 million of total excess and obsolete provisions, $2.3 million was related to Semiconductor Test, $0.6 million was related to Wireless Test, and $0.1 million was related to System Test.

During the three months ended October 1, 2017 and October 2, 2016, we scrapped $1.2 million and $4.6 million of inventory, respectively. During the three months ended October 1, 2017 and October 2, 2016, we sold $3.1 million and $1.8 million of previously written-down or written-off inventory, respectively. As of October 1, 2017, we had inventory related reserves for inventory which had been written-down or written-off totaling $112.2 million. We have no pre-determined timeline to scrap the remaining inventory.

Engineering and development	$	77.2		$	71.4		$	5.8
Percent of total revenues		15.3	%		17.4	%

The increase of $5.8 million in engineering and development expenses was primarily due to higher variable compensation and higher spending in System Test and Industrial Automation, partially offset by lower spending in Wireless Test.

Acquired Intangible Assets Amortization

Acquired intangible assets amortization expense was as follows:


	For the Three Months Ended
	October 1, 2017			October 2, 2016			Dollar Change
	(in millions)
Acquired intangible assets amortization	$	7.0		$	8.5		$	(1.5	)
Percent of total revenues		1.4	%		2.1	%

Acquired intangible assets amortization expense decreased primarily in the Industrial Automation segment due to intangible assets that became fully amortized in June, 2017.

Restructuring and Other

During the three months ended October 1, 2017, we recorded $5.1 million of property insurance recovery related to the Japan earthquake, a $0.4 million credit related to previously impaired lease termination of a Wireless Test facility in Sunnyvale, CA, and a $0.3 million credit for the decrease in the fair value of the Universal Robots contingent consideration liability, partially offset by $0.8 million of Japan earthquake related expenses, and $0.6 million recorded for employee severance charges, primarily in Semiconductor Test.

During the three months ended October 2, 2016, we recorded $8.0 million for the increase in the fair value of the Universal Robots contingent consideration liability, and $4.2 million for employee severance charges, primarily in Semiconductor Test and Wireless Test.

Interest and Other


	For the Three Months Ended
	October 1, 2017			October 2, 2016			Dollar Change
	(in millions)

Interest expense		5.4			0.6			4.8
Other (income) expense, net		0.4			(0.9	)		1.3

Interest income increased by $1.6 million due primarily to higher cash and marketable securities balances and higher interest rates in the third quarter of 2017. Interest expense increased by $4.8 million due primarily to interest expense related to our convertible senior notes. Other (income) expense, net included net foreign exchange losses in the third quarter of 2017 and net foreign exchange gains in the third quarter of 2016.

Income (Loss) Before Income Taxes


	For the Three Months Ended
	October 1, 2017			October 2, 2016			Dollar Change
	(in millions)
Semiconductor Test	$	116.8		$	67.7		$	49.1
Wireless Test		7.5			1.1			6.4
Industrial Automation		3.4			(4.7	)		8.1
System Test		(3.3	)		1.6			(4.9	)
Corporate (1)		3.1			(6.0	)		9.1

Total	$	127.4		$	59.7		$	67.7

(1)

Included in Corporate are: contingent consideration adjustments, pension and postretirement plans actuarial gains (losses), impairment of fixed assets and expenses related to the Japan earthquake, property insurance recovery, interest income, interest expense and net foreign exchange gains (losses).

The increase in income before income taxes in Semiconductor Test was driven primarily by increased sales and higher gross margin due to favorable product mix. The increase in income before income taxes in Wireless Test was primarily due to lower intangible assets amortization, lower operating expenses and higher demand for cellular test systems in the third quarter of 2017. The increase in income before income taxes in Industrial Automation was primarily due to higher demand for collaborative robots. The decrease in income before income taxes in System Test was primarily due to lower sales in Storage Test of 3.5” hard disk drive testers for cloud storage and increased spending for new product development.

Income Taxes

The effective tax rate for the three months ended October 1, 2017 and October 2, 2016 was 18.8% and (6.9%), respectively. The increase in the effective tax rate is primarily attributable to a shift in the geographic distribution of income which increased income subject to taxation in the U.S. relative to lower tax rate jurisdictions, the effect of a U.S. non-deductible goodwill impairment charge and decreases in discrete tax benefits.

Nine Months 2017 Compared to Nine Months 2016

Revenues

Revenues by our four reportable segments were as follows:


	For the Nine Months Ended
	October 1, 2017		October 2, 2016		Dollar Change
	(in millions)
Semiconductor Test	$	1,345.6	$	1,097.6	$	248.0

During the nine months ended October 1, 2017 and October 2, 2016, we sold $6.4 million and $8.0 million of previously written-down or written-off inventory, respectively. As of October 1, 2017, we had inventory related reserves for inventory which had been written-down or written-off totaling $112.2 million. We have no pre-determined timeline to scrap the remaining inventory.

Selling and Administrative

Selling and administrative expenses were as follows:


	For the Nine Months Ended
	October 1, 2017			October 2, 2016			Dollar Change
	(in millions)
Selling and administrative	$	260.3		$	239.4		$	20.9
Percent of Total Revenues		15.7	%		17.4	%

The increase of $20.9 million in selling and administrative expenses was due primarily to higher variable compensation and higher spending in Industrial Automation, partially offset by lower spending in Wireless Test.

Engineering and development expenses were as follows:


	For the Nine Months Ended
	October 1, 2017			October 2, 2016			Dollar Change
	(in millions)
Engineering and development	$	235.1		$	221.0		$	14.1
Percent of Total Revenues		14.2	%		16.1	%

The increase of $14.1 million in engineering and development expenses was primarily due to higher variable compensation and higher spending in System Test and Industrial Automation, partially offset by lower spending in Wireless Test.

Acquired Intangible Assets Amortization

Acquired intangible assets amortization expense was as follows:


	For the Nine Months Ended
	October 1, 2017			October 2, 2016			Dollar Change
	(in millions)
Acquired intangible assets amortization	$	23.1		$	44.7		$	(21.6	)
Percent of Total Revenues		1.4	%		3.3	%

Acquired intangible assets amortization expense decreased primarily in the Wireless Test segment due to the impairment of acquired intangible assets in the second quarter of 2016 and in the Industrial Automation segment due to intangible assets that became fully amortized in June, 2017.

Goodwill Impairment

We assess goodwill for impairment at least annually, in the fourth quarter, as of December 31, or on an interim basis between annual tests when events or circumstances indicate that it is more-likely-than-not that the fair value of a reporting unit is less than its carrying value. In the second quarter of 2016, the Wireless Test reporting unit (which is our Wireless Test operating and reportable segment) reduced headcount by 11% as a result of a sharp decline in projected demand attributable to an estimated smaller future wireless test market. The decrease in projected demand was due to lower forecasted buying from our largest Wireless Test segment customer (who had previously contributed between 51% and 73% of annual Wireless Test sales since the LitePoint acquisition in 2011) as a result of the customer’s numerous operational efficiencies; slower smartphone growth rates; and a slowdown of new wireless technology adoption. We considered the headcount reduction and sharp decline in projected demand to be a triggering event for an interim goodwill impairment test. Following the interim goodwill impairment test, we recorded a goodwill impairment charge of $254.9 million in the second quarter of 2016.

Acquired Intangible Assets Impairment

We review long-lived assets for impairment whenever events or changes in business circumstances indicate that the carrying amount of the assets may not be fully recoverable or that the useful lives of these assets are no longer appropriate. As a result of the Wireless Test segment goodwill impairment review in the second quarter of 2016, we performed an impairment test of the Wireless Test segment’s intangible and long-lived assets based on a comparison of the estimated undiscounted cash flows to the recorded value of the assets. If undiscounted cash flows for the asset are less than the carrying amount, the asset is written down to its estimated fair value based on a discounted cash flow analysis. The cash flow estimates used to determine the impairment contain management’s best estimates using appropriate assumptions and projections at that time. As a result of the analysis, we recorded an $83.3 million impairment charge in the second quarter of 2016.

Restructuring and Other

During the nine months ended October 1, 2017, we recorded $2.0 million for employee severance charges, primarily in Industrial Automation and Corporate, $1.8 million for the increase in the fair value of the Universal Robots contingent consideration liability, $0.9 million for a lease impairment of a Wireless Test facility in Sunnyvale, CA, which was terminated in September 2017, and $0.8 million of Japan earthquake related expenses, partially offset by $5.1 million of property insurance recovery related to the Japan earthquake.

During the nine months ended October 2, 2016, we recorded $10.5 million for the increase in the fair value of contingent consideration liability, of which $9.9 million was related to Universal Robots and $0.6 million was related to AIT, $5.9 million for employee severance charges, primarily in Semiconductor Test and Wireless Test, $4.2 million for an impairment of fixed assets, and $0.9 million for Japan earthquake related expenses, partially offset by $5.1 million of property insurance recovery related to the Japan earthquake.

(1)

Included in Corporate are: contingent consideration adjustments, pension and postretirement plans actuarial gains (losses), impairment of fixed assets and expenses related to the Japan earthquake, property insurance recovery and proceeds, interest income, interest expense and net foreign exchange gains (losses).

The increase in income before income taxes in Semiconductor Test was driven primarily by increased sales and higher gross margin due to favorable product mix. The increase in income before income taxes in Wireless Test was primarily due to goodwill and intangible assets impairment charges in 2016 and lower intangible assets amortization, lower operating expenses and higher demand for cellular and connectivity test systems in 2017. The increase in income before income taxes in Industrial Automation was due to higher demand for collaborative robots. The decrease in income before income taxes in System Test was primarily due to lower sales in Storage Test of 3.5” hard disk drive testers for cloud storage and increased spending for new product development.

Income Taxes

The effective tax rate for the nine months ended October 1, 2017 and October 2, 2016 was 14.7% and 3.7%, respectively. The increase in the effective tax rate is primarily attributable to a shift in the geographic distribution of income which increased income subject to taxation in the U.S. relative to lower tax rate jurisdictions, the effect of a U.S. non-deductible goodwill impairment charge and decreases in discrete tax benefits.

Contractual Obligations

The following table reflects our contractual obligations as of October 1, 2017:

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

Liquidity and Capital Resources

Our cash, cash equivalents and marketable securities balances increased by $235.7 million in the nine months ended October 1, 2017 to $1,848 million.

In the nine months ended October 1, 2017, changes in operating assets and liabilities provided cash of $6.3 million. This was due to a $44.5 million increase in operating assets partially offset by a $50.8 million increase in operating liabilities.

The increase in operating assets was primarily due to a $75.6 million increase in accounts receivable due to higher sales, partially offset by a $23.8 million decrease in inventories and a $7.4 million decrease in prepayments and other assets.

The increase in operating liabilities was due to a $20.5 million increase in other accrued liabilities, a $15.8 million increase in income taxes, a $3.0 million increase in accrued employee compensation due primarily to variable compensation, and a $34.5 million increase in deferred revenue and customer advance payments, partially offset by an $18.1 million decrease in accounts payable and $4.9 million of retirement plan contributions.

Investing activities during the nine months ended October 1, 2017, used cash of $188.3 million, due to $1,036.5 million used for purchases of marketable securities and $73.2 million used for purchases of property, plant and equipment, partially offset by $473.3 million and $443.2 million in proceeds from maturities and sales of marketable securities, respectively, and proceeds from property insurance of $5.1 million related to the Japan earthquake.

Financing activities during the nine months ended October 1, 2017, used cash of $182.7 million, due to $151.8 million used for the repurchase of 4.6 million shares of common stock at an average price of $32.66 per share, $41.7 million used for dividend payments, $12.6 million used for payment related to net settlement of employee stock compensation awards and $1.1 million used for a payment related to AIT acquisition contingent consideration, partially offset by $24.5 million from the issuance of common stock under employee stock purchase and stock option plans.

In the nine months ended October 2, 2016, changes in operating assets and liabilities provided cash of $93.1 million. This was due to an $81.0 million decrease in operating assets and a $12.1 million increase in operating liabilities.

The decrease in operating assets was due to a $45.7 million decrease in accounts receivable due to increased collections and a $48.6 million decrease in inventories, partially offset by a $13.3 million increase in prepayments and other assets. The increase in operating liabilities was due to a $53.4 million increase in deferred revenue and customer advance payments, a $15.4 million increase in other accrued liabilities and a $4.2 million increase in accrued income taxes, partially offset by a $24.2 million decrease in accrued employee compensation due primarily to variable compensation, a $30.8 million decrease in accounts payable, and $5.9 million of retirement plan contributions.

Investing activities during the nine months ended October 2, 2016 used cash of $268.1 million, due to $875.8 million used for purchases of marketable securities and $66.3 million used for purchases of property, plant and equipment, partially offset by $466.7 million and $202.2 million in proceeds from sales and maturities of marketable securities, respectively, and proceeds from property insurance of $5.1 million related to the Japan earthquake.

Financing activities during the nine months ended October 2, 2016 used cash of $119.1 million, due to $85.1 million used for the repurchase of 4.3 million shares of common stock at an average price of $19.69 per share, $36.5 million used for dividend payments, $11.7 million used for a payment related to the Universal Robots acquisition contingent consideration, and $9.2 million used for payment related to net settlement of employee stock compensation awards partially offset by $20.1 million from the issuance of common stock under employee stock purchase and stock option plans and $3.4 million from the tax benefit related to employee stock compensation awards.

In January 2017, May 2017 and August 2017, our Board of Directors declared a quarterly cash dividend of $0.07 per share. In the nine months ended October 1, 2017, dividend payments were $41.7 million.

In January 2016, May 2016, and August 2016, our Board of Directors declared a quarterly cash dividend of $0.06 per share. In the nine months ended October 2, 2016, dividend payments were $36.5 million.

In December 2016, the Board of Directors approved a $500 million share repurchase authorization which commenced on January 1, 2017. We intend to repurchase at least $200 million in 2017. During the nine months ended October 1, 2017, we repurchased 4.6 million shares of common stock at an average price of $32.66 per share, for a total price of $151.8 million. The total price includes commissions and is recorded as a reduction to retained earnings.

During the nine months ended October 2, 2016, we repurchased 4.3 million shares of common stock at an average price of $19.69, for a total cost of $85.1 million.

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 $1,106 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.

Equity Compensation Plans

As discussed in Note O: “Stock Based Compensation” in our 2016 Form 10-K, we have a 1996 Employee Stock Purchase Plan and a 2006 Equity and Cash Compensation Incentive Plan (the “2006 Equity Plan”).

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

Recently Issued Accounting Pronouncements

On March 10, 2017, the FASB issued ASU 2017-07, “Compensation—Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost.” This ASU provides guidance on presentation of net periodic pension cost and net periodic postretirement benefit cost. The new standard requires the service cost component to be presented in the same line item as other employee compensation costs arising from services rendered during the period. The other components of net benefit cost such as interest cost, amortization of prior service cost, and actuarial gains or losses, are required to be presented separately outside of income or loss from operations. The presentation of service cost should be applied retrospectively. The guidance is effective for fiscal years beginning after December 15, 2017. Early adoption is permitted. This guidance will impact the presentation of our consolidated financial statements. Upon adoption of the new standard, we will present interest cost, amortization of prior service cost, and actuarial gains or losses within other (income) expense, net.

On January 26, 2017, the FASB issued ASU 2017-04, “Intangibles—Goodwill and Other (Topic 350): Simplifying the Accounting for Goodwill Impairment.” The new guidance removes Step 2 of the goodwill impairment test, which requires a hypothetical purchase price allocation. Goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. All other goodwill impairment guidance will remain largely unchanged. Entities will continue to have the option to perform a qualitative assessment to determine if a quantitative impairment test is necessary. The same one-step impairment test will be applied to goodwill at all reporting units, even those with zero or negative carrying amounts. Entities will be required to disclose the amount of goodwill at reporting units with zero or negative carrying amounts. The revised guidance will be applied prospectively, and is effective in 2020. Early adoption is permitted for any impairment tests performed after January 1, 2017. We are currently evaluating the impact of this ASU on our financial position, results of operations and statements of cash flows.

In October 2016, the FASB issued ASU 2016-16, “Accounting for Income Taxes: Intra-Entity Asset Transfers of Assets Other than Inventory.” Under current Generally Accepted Accounting Principles (“GAAP”), the tax effects of intra-entity asset transfers are deferred until the transferred asset is sold to a third party or otherwise recovered through use. The new guidance requires recognition of the tax expense from the sale of the asset in the seller’s tax jurisdiction when the transfer occurs, even though the pre-tax effects of that transaction are eliminated in consolidation. Any deferred tax asset that arises in the buyer’s jurisdiction would also be recognized at the time of the transfer. The new guidance does not apply to intra-entity transfers of inventory. The income tax consequences from the sale of inventory from one member of a consolidated entity to another will continue to be deferred until the inventory is sold to a third party. The new guidance will be effective in fiscal years beginning after December 15, 2017. Early adoption is permitted. The modified retrospective approach will be required for transition to the new guidance, with a cumulative-effect adjustment recorded in retained earnings as of the beginning of the period of adoption. We do not expect this ASU to have a material impact on our financial position, results of operations and statements of cash flows.

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 an 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 statements of operations. The new standard is effective for annual periods beginning after December 15, 2018 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 January 2016, the FASB issued 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 beginning after December 15, 2017. We are currently evaluating the impact of this ASU on our financial position and results of operations.

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 one year. For us, the standard will be effective in the first quarter of 2018. 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 selected the modified retrospective transition method.

We have completed our preliminary assessment of the financial statement impact of the new standard and do not expect this ASU to have a material impact on our financial position or results of operations. This preliminary assessment is based on a review of the types and number of revenue arrangements currently in place including the review of individual customer contracts related to these revenue streams. The exact impact of the new standard will be dependent on facts and circumstances at adoption and could vary from quarter to quarter. Based on our preliminary assessment we do not expect any major changes to be made to existing accounting systems or internal controls. We will be required to record cumulative effect adjustments to retained earnings upon adopting the new standard in the first quarter of 2018.

Item 3:

Quantitative and Qualitative Disclosures about Market Risks

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 March 1, 2017. 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, 2016.

In addition to market risks described in our Annual Report on Form 10-K, we have an equity price risk related to the fair value of our convertible senior unsecured notes issued in December 2016. In December 2016, Teradyne issued $460 million aggregate principal amount of 1.25% convertible senior unsecured notes (the

“Notes”) due December 15, 2023. As of October 1, 2017, the Notes had a fair value of $613.2 million. The table below provides a sensitivity analysis of hypothetical 10% changes of Teradyne’s stock price as of the end of the third quarter of 2017 and the estimated impact on the fair value of the Notes. The selected scenarios are not predictions of future events, but rather are intended to illustrate the effect such event may have on the fair value of the Notes. The fair value of the Notes is subject to equity price risk due to the convertible feature. The fair value of the Notes will generally increase as Teradyne’s common stock price increases and will generally decrease as the common stock price declines in value. The change in stock price affects the fair value of the convertible senior notes, but does not impact Teradyne’s financial position, cash flows or results of operations due to the fixed nature of the debt obligation. Additionally, we carry the Notes at face value less unamortized discount on our balance sheet, and we present the fair value for required disclosure purposes only. In connection with the offering of the Notes we also sold warrants to the option counterparties. These transactions have been accounted for as an adjustment to our shareholders’ equity. The convertible note hedge transactions are expected to reduce the potential equity dilution upon conversion of the Notes. The warrants along with any shares issuable upon conversion of the Notes will have a dilutive effect on our earnings per share to the extent that the average market price of our common stock for a given reporting period exceeds the applicable strike price or conversion price of the warrants or Notes, respectively.


Hypothetical Change in Teradyne Stock Price	Fair Value		Estimated Change in Fair Value			Hypothetical Percentage Increase (Decrease) in Fair Value

No Change		613,238		—			—

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.
