NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)

| • |  | wireless test (“Wireless Test”) systems.

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, 2019 condensed consolidated balance sheet data was derived from audited financial statements but does not include all disclosures required by United States of America generally accepted accounting principles (“U.S. GAAP”) for complete financial statements. 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 2, 2020, for the year ended December 31, 2019.
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. Due to the
COVID-19
pandemic, there has been uncertainty and disruption in the global economy and our markets. Teradyne is not aware of any specific event or circumstance that would require an update to its estimates or judgments or a revision of the carrying value of its assets or liabilities as of November
2
, 2020, the date of issuance of this Quarterly Report on Form
10-Q.
These estimates may change, as new events occur and additional information is obtained. Actual results could differ significantly from these estimates under different assumptions or conditions.
Goodwill
On January 26, 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“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. Teradyne adopted this standard on January 1, 2020, on a prospective basis. The adoption of ASU
2017-04
did not have a material impact on the consolidated statement of operations, cash flows, or earnings per share. Teradyne assesses goodwill for impairment at least annually in the fourth quarter, as of December 31, on a reporting unit basis, or more frequently, when events and circumstances occur indicating that the recorded goodwill may be impaired. Under ASU
2017-04,
goodwill impairment will 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.

Table of Contents
Credit Losses
In June 2016, the FASB issued ASU
2016-13,
“Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” This standard introduced the expected credit losses methodology for the measurement of credit losses on financial assets that are not measured at fair value through net income and replaces the “incurred loss” model with an “expected credit loss” model that requires consideration of a broader range of information to estimate expected credit losses over the lifetime of the asset. Teradyne adopted this standard on January 1, 2020 on a modified retrospective basis. The adoption of ASU
2016-13
did not have a material impact on the consolidated statement of operations, balance sheets, cash flows, or earnings per share.
C. RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS
In August 2020, the FASB issued ASU
2020-06
– “Debt - Debt with Conversion and Other Options and Derivatives and Hedging - Contracts in Entity’s Own Equity,” which simplifies the accounting for convertible debt instruments by reducing the number of accounting models and the number of embedded conversion features that could be recognized separately from the primary contract. This ASU requires a convertible debt instrument to be accounted for as a single liability measured at its amortized cost, as long as no other features require bifurcation and recognition as derivatives. This ASU requires an entity to use the
if-converted
method in the diluted earnings per share calculation for convertible instruments. This ASU will be effective for Teradyne in on January 1, 2022, with early adoption permitted beginning on January 1, 2021. This ASU permits the use of either the modified retrospective or fully retrospective method of transition. Teradyne is evaluating the timing and effects of the adoption of this ASU on its financial statements.
D. ACQUISITIONS
AutoGuide LLC
On November 13, 2019, Teradyne acquired 100% of the membership interests of AutoGuide, LLC (“AutoGuide”), a maker of high-payload autonomous mobile robots (“AMRs”), based in Chelmsford, MA, an emerging and fast growing segment of the global forklift market. The total purchase price was approximately $81.6 million, which included cash paid of approximately $57.6 million and $24.0 million in fair value of contingent consideration payable upon achievement of certain performance targets, extending potentially through 2022. At
Septem
ber
2
7
, 2020, the maximum contingent consideration that could be paid is $106.9 million.
The contingent consideration is payable upon achievement of certain thresholds and targets for revenue and earnings before interest and taxes for periods from January 1, 2019 to December 31, 2020, January 1, 2019 to December 31, 2021, and January 1, 2019 to December 31, 2022.
The valuation of the contingent consideration is dependent on the following assumptions: forecasted revenues, revenue volatility, earnings before interest and taxes, and discount rate. These assumptions were estimated based on a review of the historical and projected results.
The AutoGuide acquisition was accounted for as a business combination and, accordingly, the results have been included in Teradyne’s consolidated results of operations from the date of acquisition. AutoGuide’s AMRs are used for material transport of payloads up to 4,500 kg in manufacturing, warehouse and logistics applications. These products complement Mobile Industrial Robots Aps (“MiR”) lower payload products and expand the Industrial Automation segment, which is a key component of Teradyne’s growth strategy.
The allocation of the total purchase price to AutoGuide’s net tangible assets and identifiable intangible assets was based on their estimated fair values as of the acquisition date. The excess of the purchase price over the identifiable intangible assets and net tangible assets in the amount of $41.2 million was allocated to goodwill, which is deductible for tax purposes. AutoGuide’s results have been included in Teradyne’s Industrial Automation segment from the date of acquisition.

Table of Contents
The following table represents the final allocation of the purchase price:

|  | Purchase Price Allocation |
|  | (in thousands) |
Goodwill |  | $ | 41,223 |
Intangible assets |  |  | 37,660 |
Tangible assets acquired and liabilities assumed: |  |  |  |
Other current assets |  |  | 3,661 |
Non-current assets |  |  | 1,227 |
Accounts payable and current liabilities |  |  | (1,223 | )
Long-term other liabilities |  |  | (949 | )
Total purchase price |  | $ | 81,599 |

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

|  | Fair Value |  |  | Estimated Useful Life |
|  | (in thousands) |  |  | (in years) |
Developed technology |  | $ | 24,590 |  |  |  | 6.0 |
Customer relationships |  |  | 7,360 |  |  |  | 6.0 |
Trademarks and tradenames |  |  | 5,450 |  |  |  | 7.0 |
Backlog |  |  | 260 |  |  |  | 0.3 |
Total intangible assets |  | $ | 37,660 |  |  |  | 6.1 |

Basic |  | $ | 0.80 |  |  | $ | 1.97 |
Diluted |  | $ | 0.75 |  |  | $ | 1.89 |

Lemsys SA
On January 30, 2019, Teradyne acquired all of the issued and outstanding shares of Lemsys SA (“Lemsys”) for a total purchase price of approximately $9.1 million. Lemsys strengthens Teradyne’s position in the electrification trends of vehicles, solar and wind power, and industrial applications. The Lemsys acquisition was accounted for as a business combination and, accordingly, the results have been included in Teradyne’s Semiconductor Test segment from the date of acquisition. Teradyne’s final allocation of the purchase price was goodwill of $1.4 million, which is not deductible for tax purposes, acquired intangible assets of $4.6 million with an average estimated useful life of 5.2 years, and $3.1 million of net tangible assets. The acquisition was not material to Teradyne’s consolidated financial statements.

(b) | In the nine months ended September 27, 2020, the fair value of contingent consideration for the earn-outs in connection with the acquisition of MiR decreased by $3.5 million due to lower forecasted results.

(c) | In the three and nine months ended September 29, 2019, the fair value of contingent consideration for the earn-out in connection with the acquisition of MiR decreased by $7.8 million and $16.5 million, respectively, primarily due to a decrease in the forecasted revenue, partially offset by impact from the modification of the earn-out structure in the three months ended September 29, 2019.

(d) | In the nine months ended September 27, 2020, Teradyne paid $8.9 million of contingent consideration for the earn-out in connection with the acquisition of MiR.

(e) | In the nine months ended September 29, 2019, Teradyne paid $30.8 million and $3.8 million of contingent consideration for the earn-outs in connection with the acquisition of MiR and Universal Robots A/S (“Universal Robots”), respectively.

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

As of September 27, 2020, the significant unobservable inputs used in the Monte Carlo simulation to fair value the AutoGuide and MiR contingent consideration include forecasted revenues, revenue volatility, earnings before interest and taxes, and discount rate. Increases or decreases in the inputs would result in a higher or lower fair value measurement.
As of September 27, 2020, the maximum amount of contingent consideration that could be paid in connection with the acquisition of AutoGuide is $106.9 million. The
earn-out
periods end on December 31, 2020, December 31, 2021 and December 31, 2022.
As of September 27, 2020, the maximum amount of contingent consideration that could be paid in connection with the acquisition of MiR is $65.8 million. The remaining
earn-out
period ends on December 31, 2020.

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 September 27, 2020 and December 31, 2019 was $111.5 million and $144.9 million, respectively.
Gains and losses on foreign currency forward contracts and foreign currency remeasurement gains and losses on monetary assets and liabilities are included in other (income) expense, net.

Convertible Senior Notes
On December 12, 2016, Teradyne completed a private offering of $460.0 million aggregate principal amount of 1.25% convertible senior unsecured notes (the “Notes”) due December 15, 2023 and received net proceeds, after issuance costs, of approximately $450.8 million, $33.0 million of which was used to pay the net cost of the convertible note hedge transactions and $50.1 million of which was used to repurchase 2.0 million shares of Teradyne’s common stock under its existing stock repurchase program from purchasers of the Notes in privately negotiated transactions effected through one of the initial purchasers or its affiliates conducted concurrently with the pricing of the Note offering. The Notes will mature on December 15, 2023, unless earlier repurchased
16

Table of Contents
or converted. The Notes bear interest from December 12, 2016 at a rate of
1.25
% per year payable semiannually in arrears on June 15 and December 15 of each year. 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, only 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. As of September 27, 2020, the conversion price was approximately $31.57 per share of Teradyne’s common stock. The conversion rate is subject to adjustment under certain circumstances. As of November 2, 2020, fourteen holders exercised the option to convert twenty-nine thousand dollars’ worth of Notes.
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 conversion price of the Notes of $31.57. The Note Hedge Transactions cover, subject to customary anti-dilution adjustments, approximately 14.6 million shares of Teradyne’s common 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 14.6 million shares of common stock. As of September 27, 2020, the strike price of the warrants was approximately $39.62 per share. The strike price is subject to adjustment under certain circumstances. 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. The net cost of the Note Hedge Transactions, after being partially offset by the proceeds from the sale of the warrants, was approximately $33.0 million.
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 considered the guidance of ASC
815-40,
“Derivatives and Hedging—Contracts in Entity’s Own Equity,”
and concluded that the convertible note hedge is both indexed to Teradyne’s common stock and should be classified in stockholders’ equity in its statements of financial position. The convertible note hedge is considered indexed to Teradyne’s common 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 common stock.
Teradyne assessed whether the convertible note hedge should be classified as equity under ASC
815-40.
In the Note Hedge Transactions contract the settlement terms permit net cash settlement or net share settlement, at the option of Teradyne. Therefore, the criteria as set forth in ASC
815-40
were evaluated by Teradyne. In reviewing the criteria, Teradyne noted the following: (1) the convertible note hedge does not require Teradyne to issue shares; (2) there is no requirement to net cash settle the convertible note hedge for failure to make timely filings with the SEC; (3) in the case of termination, the convertible note hedge is settled in the same consideration as the holders of the underlying stock; (4) the counterparty does not have rights that rank higher than those of a shareholder of the stock underlying the convertible note hedge; and (5) there is no requirement to post collateral. Based on its analysis of those criteria, Teradyne concluded that the convertible note hedge should be recorded in equity and no further adjustment should be made in future periods to adjust the value of the convertible note hedge.
17

Table of Contents
Teradyne analyzed the Warrant Transactions under ASC
815-40,
“Derivatives and Hedging—Contracts in Entity’s Own Equity,”
and other relevant literature, and determined that it met the criteria for classification as an equity transaction and is considered indexed to Teradyne’s common stock. As a result, Teradyne recorded the proceeds from the warrants as an increase to additional
paid-in
capital. Teradyne does not recognize subsequent changes in fair value of the warrants in its financial statements.
The provisions of ASC
470-20,
“
Debt with Conversion and Other Options,
” are applicable to the Notes. ASC
470-20
requires Teradyne to separately account for the liability (debt) and equity (conversion feature) components of the Notes in a manner that reflects Teradyne’s nonconvertible debt borrowing rate at the date of issuance when interest cost is recognized in subsequent periods. Teradyne allocated $100.8 million of the $460.0 million principal amount of the Notes to the equity component, which represents a discount to the debt and will be amortized to interest expense using the effective interest method through December 2023. Accordingly, Teradyne’s effective annual interest rate on the Notes will be approximately 5.0%. The Notes are classified as long-term debt in the balance sheet based on their December 15, 2023 maturity date. Debt issuance costs of approximately $7.2 million are being amortized to interest expense using the effective interest method over the seven-year term of the Notes. As of September 27, 2020, debt issuance costs were approximately $3.6 million.

As of September 27, 2020, the remaining unamortized discount was $53.8 million, which will be amortized over 3.3 years using the effective interest rate method. The carrying amount of the equity component was $100.8 million. As of September 27, 2020, the
if-converted
value of the Notes was $1,132.4 million.
Revolving Credit Facility
On May 1, 2020, Teradyne entered into a credit agreement (the “Credit Agreement”) with Truist Bank, as administrative agent and collateral agent, and the lenders party thereto. The Credit Agreement provides for a three-year, senior secured revolving credit facility of $400.0 million (the “Credit Facility”). The Credit Agreement further provides that, subject to customary conditions, Teradyne may seek to obtain from existing or new lenders incremental commitments under the Credit Facility in an aggregate principal amount not to exceed $150.0 million.
Proceeds from the Credit Facility may be used for general corporate purposes and working capital. During the
nine
months ended September 27, 2020, Teradyne incurred $3.5 million in costs related to the revolving credit facility. These costs are being amortized over the
three-year
term of the revolving credit facility and are included in interest expense in the statement of operations. As of November
2
, 2020, 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 0.50% to 1.25% per annum or LIBOR, a minimum of 0.75%, plus a margin ranging from 1.50% to 2.25% per annum, based on the consolidated leverage ratio of Teradyne. In addition, Teradyne will pay a commitment fee on the unused portion of the commitments under the Credit Facility ranging from 0.25% to 0.40% per annum, based on the then applicable consolidated leverage ratio.

Table of Contents
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 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.
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.
As of November
2
, 2020, Teradyne was in compliance with all covenants.

L. STOCK-BASED COMPENSATION
Under Teradyne’s stock compensation plans, Teradyne grants service-based restricted stock units, performance-based restricted stock units and stock options, and employees are eligible to purchase Teradyne’s common stock through its Employee Stock Purchase Plan (“ESPP”).
Service-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 earlier of (a) the first anniversary of the grant date or (b) the date of the following year’s Annual Meeting of Shareholders. Teradyne expenses the cost of the restricted stock unit awards subject to service-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.
Performance-based restricted stock units (“PRSUs”) granted to Teradyne’s executive officers may have a performance metric based on relative total shareholder return (“TSR”). 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 0% to 200% of the target shares capped at four times the grant date value for grants prior to 201
9
. 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 shorter of the three-year service period or the period from the grant to the date described in the retirement provisions below. Compensation expense for executive officers meeting the retirement provisions prior to the grant date is recognized during the
yea
r
following the grant. 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.
PRSUs granted to Teradyne’s executive officers may also have 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 0% to 200% of the target shares. The PBIT PRSUs will vest upon the three-year anniversary of the grant date. Compensation expense is recognized

Table of Contents
on a straight-line basis over the shorter of the three-year service period or the period from the grant date to the date described in the retirement provisions below. Compensation expense for executive officers meeting the retirement provisions prior to the grant date is recognized during the year following the grant. 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.
If a PRSU 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.
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.
During the nine months ended September 27, 2020 and September 29, 2019, Teradyne granted 0.4 million and 0.7 million of service-based restricted stock unit awards to employees at a weighted average grant date fair value of $70.76 and $36.85, respectively, and 0.1 million of service-based restricted stock unit awards to
non-employee
directors at a weighted average grant date fair value of $64.99 and $48.03, respectively.
During the nine months ended September 27, 2020 and September 29, 2019, Teradyne granted 0.1 million of PBIT PRSUs with a grant date fair value of $70.94 and $36.88, respectively.
During the nine months ended September 27, 2020 and September 29, 2019, Teradyne granted 0.1 million of TSR PRSUs, with a grant date fair value of $89.93 and $51.51, respectively. The fair value was estimated using the Monte Carlo simulation model with the following assumptions:

|  | For the Nine Months Ended |
|  | September 27, |  |  | September 29, |
|  | 2020 |  |  | 2019 |
Risk-free interest rate |  |  | 1.5 | % |  |  | 2.6 | %
Teradyne volatility-historical |  |  | 34.9 | % |  |  | 31.9 | %
NYSE Composite Index volatility-historical |  |  | 11.4 | % |  |  | 11.9 | %
Dividend yield |  |  | 0.6 | % |  |  | 1.0 | %

Expected volatility was based on the historical volatility of Teradyne’s stock and the NYSE
Composite
Index 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 $0.40 per share divided by Teradyne’s stock price on the grant date of $72.10 for the 2020 grant and an estimated annual dividend amount of $0.36 per share divided by Teradyne’s stock price on the grant date of $36.75 for the 2019 grant.
During the nine months ended September 27, 2020 and September 29, 2019, Teradyne granted 0.1 million of service-based stock options to executive officers at a weighted average grant date fair value of $20.67 and $10.61, respectively.
The fair value of stock options was estimated using the Black-Scholes option-pricing model with the following assumptions:

|  | For the Nine Months Ended |
|  | September 27, |  |  | September 29, |
|  | 2020 |  |  | 2019 |
Expected life (years) |  |  | 5.0 |  |  |  | 5.0 |
Risk-free interest rate |  |  | 1.6 | % |  |  | 2.5 | %
Volatility-historical |  |  | 31.6 | % |  |  | 30.1 | %
Dividend yield |  |  | 0.6 | % |  |  | 1.0 | %

Teradyne determined the stock options’ expected life based upon historical exercise data for executive officers, the age of the executive officers and the terms of the stock option grant. Volatility was determined using historical volatility for a period equal to the expected life. The risk-free 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 $0.40 per share divided by Teradyne’s stock price on the grant date of $72.10 for the 2020 grant and an estimated annual dividend amount of $0.36 per share divided by Teradyne’s stock price on the grant date of $37.95 for the 2019 grant.

(1) | Incremental shares from assumed conversion of the convertible notes was calculated using the difference between the average Teradyne stock price for the period and the conversion price of $31.57, multiplied by 14.6 million shares. The result of this calculation, representing the total intrinsic value of the convertible debt, was divided by the average Teradyne stock price for the period.

(2) | Convertible notes hedge warrant shares were calculated using the difference between the average Teradyne stock price for the period and the warrant price of $39.62, multiplied by 14.6 million shares. The result of this calculation, representing the total intrinsic value of the warrant, was 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 September 27, 2020 excludes the effect of the potential vesting of 0.1 million and 0.2 million, respectively, of restricted stock units because the effect would have been anti-dilutive.
The computation of diluted net income per common share for the three and nine months ended September 29, 2019 excludes the effect of the potential vesting of 0.1 million of stock options, because the effect would have been anti-dilutive.
The computation of diluted net income per share for the nine months ended September 29, 2019 excludes the effect of the potential vesting of 0.2 million of restricted stock units, because the effect would have been anti-dilutive.

Q. RETIREMENT PLANS
ASC 715,
“Compensation—Retirement Benefits”
requires an employer with a 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 at December 31. Teradyne uses a December 31 measurement date for all of its plans.
Defined Benefit Pension Plans
Teradyne has defined benefit pension plans covering a portion of domestic employees and employees of certain
non-U.S.
subsidiaries. Benefits under these plans are based on employees’ years of service and compensation. Teradyne’s funding policy is to make contributions to these plans in accordance with local laws and to the extent that such contributions are tax deductible. The assets of 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 three months ended September 27, 2020, Teradyne purchased a group annuity contract for its retiree participants in the U.S. qualified pension plan. Under the group annuity, the accrued pension obligations for approximately 115 retiree participants were transferred to an insurance company. The reduction in the pension benefit obligation and pension assets was $24.4 million. In the three and nine months ended September 27, 2020, Teradyne recorded $2.2 million of pension actuarial loss and a settlement loss of $0.5 million from interim remeasurement of U.S. Pension Plan related to the retiree group annuity transaction.
In the nine months ended September 27, 2020, Teradyne contributed $2.2 million to the U.S. supplemental executive defined benefit pension plan and $0.7 million to certain qualified pension plans for
non-U.S.
subsidiaries.

Legal Claims
Teradyne is subject to various legal proceedings and claims which have arisen in the ordinary course of business such as, but not limited to, patent, employment, commercial and environmental matters. Teradyne believes that it has meritorious defenses against all pending claims and intends to vigorously contest them. While it is not possible to predict or determine the outcomes of any pending claims or to provide possible ranges of losses that may arise, Teradyne believes the potential losses associated with all of these actions are unlikely to have a material adverse effect on its business, financial position or results of operations.
S. INCOME TAXES
A reconciliation of the United States federal statutory corporate tax rat
e
to Teradyne’s effective tax rate was as follows:

|  | For the Three Months Ended |  |  | For the Nin e Months Ended |
|  | September 27 , 2020 |  |  | September 29 , 2019 |  |  | September 27 , 2020 |  |  | September 29 , 2019 |

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 September 27, 2020, Teradyne believes that it will ultimately realize the deferred tax assets recorded on the condensed consolidated balance sheet. However, should Teradyne believe that it is
more-likely-than-not
that the deferred tax assets would not be realized, the tax provision would increase in the period in which Teradyne determined that the realizability was not likely. Teradyne considers the probability of future taxable income and historical profitability, among other factors, in assessing the realizability of the deferred tax assets.
As of September 27, 2020 and December 31, 2019, Teradyne had $17.6 million and $21.2 million, respectively, of reserves for uncertain tax positions. The $3.6 million net decrease in reserves for uncertain tax positions is primarily related to U.S. state research and development credits generated in prior years, as well as inventory cost capitalization and equity compensation in prior years.
As of September 27, 2020, Teradyne does not anticipate a material change in the balance of unrecognized tax benefits during the next twelve months.
Teradyne recognizes interest and penalties related to income tax matters in income tax expense. As of September 27, 2020 and December 31, 2019, $1.4 million and $1.4 million, respectively, of interest and penalties were accrued for uncertain tax positions. For the nine months ended September 27, 2020 and September 29, 2019, expense of $0.0 million and $0.2 million, respectively, 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 September 27, 2020 was $24.9 million, or $0.14 per diluted share. The tax savings due to the tax holiday for the nine months ended September 29, 2019 was $12.0 million, or $0.07 per diluted share. The tax holiday is scheduled to expire on December 31, 2020. Teradyne is currently in discussion with the Singapore Economic Development Board with respect to extension of the tax holiday for periods after December 31, 2020.

for the year ended December 31, 2019. 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 robotic arms, autonomous mobile robots and advanced robotic control software used by global manufacturing and light industrial customers to improve quality, increase manufacturing and material handling efficiency and decrease manufacturing costs. Our automatic test equipment and industrial automation products and services include:

| • |  | semiconductor test (“Semiconductor Test”) systems;

| • |  | defense/aerospace (“Defense/Aerospace”) test instrumentation and systems, storage and system level test (“Storage Test”) systems, and circuit-board test and inspection (“Production Board Test”) systems (collectively these products represent “System Test”);

| • |  | 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, autonomous mobile robots and wireless test systems.
The sales of our products and services are dependent, to a large degree, on these 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, electronics and industrial automation industries. Historically, these demand fluctuations have resulted in significant variations in our results of operations.
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. A few customers drive significant demand for our products both through direct sales and sales to the customers’ 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.
On January 30, 2019, we acquired all of the issued and outstanding shares of Lemsys SA (“Lemsys”) for a total purchase price of approximately $9.1 million. Lemsys strengthens our position in the electrification trends of vehicles, solar, wind, and industrial applications. Lemsys is included in our Semiconductor Test segment.
On November 13, 2019, we acquired 100% of the membership interests of AutoGuide, LLC (“AutoGuide”), a maker of high payload AMRs, an emerging and fast-growing segment of the global forklift market. The total purchase price was approximately $81.6 million, which included cash paid of approximately $57.6 million and $24.0 million in fair value of contingent consideration payable upon achievement of certain performance targets, extending potentially through 2022. The maximum contingent consideration that could be paid is $106.9 million. AutoGuide’s AMRs are used for material transport of payloads up to 4,500 kg in manufacturing, warehouse and logistics applications. These products complement MiR’s lower payload products. AutoGuide is included in our Industrial Automation segment.
We believe our recent acquisitions have enhanced our opportunities for growth. We intend to continue to invest in our business, grow market share in our markets and expand further our addressable markets while tightly managing our costs.

operations and could disrupt our business, workforce and operations, as well as the operations of our customers, contract manufacturers and suppliers for an uncertain period of time. We are continuing to monitor the rapidly evolving situation regarding the
COVID-19
pandemic and its impact on our business, results of operations, financial condition, liquidity and cash flows. However, despite careful tracking, we are unable to accurately predict the full impact of
COVID-19,
which will depend on future developments that are highly uncertain and cannot be predicted with accuracy, including, but not limited to, the duration and continued spread of the outbreak, its severity, the actions to contain the virus or treat its impact, and how quickly and to what extent normal economic and operating conditions can resume.
Health and Safety
In response to the
COVID-19
pandemic, we have taken proactive, aggressive action to protect the health and safety of our employees, customers, contract manufacturers and suppliers and we have complied with all government orders around the globe. The spread of
COVID-19
has caused us to modify our business practices, including implementing social distancing protocols, suspending employee travel, requiring most employees to work remotely, cancelling physical participation in meetings, and extensively and frequently disinfecting our workspaces. Around the world, the majority of our employees are working from home. However, some of our engineering, operations, supply line and customer support teams must be
on-site
at our or our customers’ facilities. We are providing those
on-site
employees with the necessary protective resources and procedures to minimize their exposure risk. We may take further actions as may be required or recommended by government authorities or that we determine are in the best interests of our employees, customers, contract manufacturers and suppliers.
Operations
We believe the
COVID-19
pandemic, and the numerous measures implemented by authorities in response, has adversely impacted our results of operations, including by increasing costs and decreasing demand in our Industrial Automation businesses, but we cannot accurately estimate the amount of the impact to our third quarter 2020 financial results or to our future financial results. In addition, restrictions on our access to manufacturing facilities or on our support operations or workforce, or similar limitations for our contract manufacturers and suppliers, and restrictions or disruptions affecting transportation, such as reduced availability of transportation and increased border controls or closures, could limit our capacity to meet customer demand which could have a material adverse effect on our financial condition and results of operations. These measures have impacted and may further impact our workforce and operations, as well as those of our customers, contract manufacturers and suppliers. The constraints and limits imposed on our operations may slow or diminish our production and research and development activities as well as application support projects with our customers. At this time, application support projects are largely on track with employees assisting customers
on-site
where necessary but with the use of enhanced safety protocols. Research and development projects are, with minor exceptions, on schedule despite the rapid shift of a significant number of our engineers working remotely. While governmental measures may be modified or extended, we expect that our manufacturing and research and development facilities will remain operational, at sufficient capacity to support production demand. We are monitoring our operations closely in an effort to avoid any potential productivity loss caused by responses to the
COVID-19
pandemic.
Supply
We have not yet experienced any significant impacts or interruptions to our supply chain as a result of the
COVID-19
pandemic. However, our suppliers have faced and may continue to face difficulties maintaining operations in light of government-ordered restrictions, including social distancing requirements and
shelter-in-place
mandates. Our supply chain team, and our suppliers, overcame numerous supply, production, and logistics obstacles in 2020, but there is no assurance we or they will be able to do so in the future. Although we regularly monitor the financial health of companies in our supply chain, financial hardship on our suppliers or
sub-suppliers
caused by the
COVID-19
pandemic could disrupt our ability to obtain components required to manufacture our products, adversely affecting our operations. To mitigate the risk of any potential supply interruptions, we may choose to increase certain inventory levels during the quarter. Additionally, restrictions or disruptions affecting transportation, such as reduced availability of air transport, port closures and increased border controls or closures, have led in some instances to higher costs and delays, both for obtaining components and shipping finished goods to customers, which could harm our profitability, make our products less competitive, or cause our customers to seek alternative suppliers.

Demand
The
COVID-19
pandemic has significantly increased economic uncertainty in our markets, which could result in a significant decrease in demand for our products for an uncertain period of time. Demand for our Test products was strong throughout the third quarter and into the fourth quarter. While there is incremental softening in the automotive sector, there is strengthening demand in mobility, 5G, and memory test. Our Industrial Automation business, however, experienced a significant decline in demand through first half of 2020 due to
COVID-19
related shutdowns affecting global manufacturing but demand recovered in the third quarter from the low point in the second quarter. We anticipate that the
COVID-19
pandemic could cause further global economic disruption that could cause demand for our products to decline, which would adversely affect our business.
Liquidity
Although there is uncertainty related to the anticipated impact of the
COVID-19
pandemic on our future results, we believe our business model, our current cash reserves and the recent steps we have taken to manage our cash flow, such as suspending our stock repurchase program, leave us well-positioned to manage our business through this crisis as it continues to unfold. We have a strong balance sheet as well as an operating model that can flex up and down with extreme demand swings and still remain profitable. Based on our analysis, we believe our existing balances of cash and cash equivalents and our currently anticipated operating cash flows will be sufficient to meet our working capital needs and other capital and liquidity requirements for the next twelve months. However, due to the uncertainty related to the future impact of the
COVID-19
pandemic, in order to bolster our liquidity position, on May 1, 2020 we entered into a credit agreement providing for a three-year, senior secured revolving credit facility of $400 million as further described in Note H: “Debt.” As of November 2, 2020, we have not borrowed any funds under the credit facility. While test demand remained strong at the beginning of our fourth quarter and our balance sheet has over $1 billion in available cash and marketable securities with no short-term debt as of November 2, 2020, the impact of the
COVID-19
pandemic on short-term Test and Industrial Automation demand remain uncertain.
We are continuing to monitor the rapidly evolving situation regarding the
COVID-19
pandemic and guidance from government authorities around the world, including federal, state and local public health authorities and may take additional actions based on their recommendations. In these circumstances, there may be developments outside our control requiring us to adjust our operating plan. As a result, given the uncertain nature of this situation, we are not able to accurately predict the full extent of the impact of
COVID-19
on our business, financial condition, results of operations, liquidity, or cash flows in the future. In addition, see Part II—Item 1A, “Risk Factors,” included herein for updates to our risk factors regarding risks associated with the
COVID-19
pandemic.
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 nine months ended September 27, 2020 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, 2019, except as noted below.
Due to the
COVID-19
pandemic, there has been uncertainty and disruption in the global economy and our markets. We are not aware of any specific event or circumstance that would require an update to our estimates or judgments or a revision of the carrying value of our assets or liabilities as of November 2, 2020, the date of issuance of this Quarterly Report on Form
10-Q.
These estimates may change, as new events occur and additional information is obtained. Actual results could differ significantly from these estimates under different assumptions or conditions.
Goodwill
On January 26, 2017, the Financial Accounting Standards Board (“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. We adopted this standard on January 1, 2020, on a prospective basis. The adoption of ASU
2017-04
did not have a material impact on the consolidated statement of operations, cash flows, or earnings per share. We assess goodwill for impairment at least annually in the fourth quarter, as of December 31, on a reporting unit basis, or more frequently, when events and circumstances occur indicating that the recorded goodwill may be impaired. Under ASU
2017-04,
goodwill impairment will 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.
Credit Losses
In June 2016, the FASB issued ASU
2016-13,
“Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” This standard introduced the expected credit losses methodology for the measurement of credit losses on financial assets that are not measured at fair value through net income and replaces the “incurred loss” model with an “expected credit loss” model that requires consideration of a broader range of information to estimate expected credit losses over the lifetime of the asset. We adopted this standard on January 1, 2020 on a modified retrospective basis. The adoption of ASU
2016-13
did not have a material impact on our consolidated statement of operations, balance sheets, cash flows, or earnings per share.

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. Due to the
COVID-19
pandemic, there has been uncertainty and disruption in the global economy and our markets. Teradyne is not aware of any specific event or circumstance that would require an update to its estimates or judgments or a revision of the carrying value of its assets or liabilities as of November 2, 2020, the date of issuance of this Quarterly Report on Form
10-Q.
These estimates may change, as new events occur and additional information is obtained. Actual results may differ significantly from these estimates under different assumptions or conditions.

Third Quarter 2020 Compared to Third Quarter 2019
Revenues
Revenues by our reportable segments were as follows:

|  | For the Three Months Ended |  |  |  |
|  | September 27, 2020 |  |  | September 29, 2019 |  |  | Dollar Change |
|  | (in millions) |
Semiconductor Test |  | $ | 592.1 |  |  | $ | 397.7 |  |  | $ | 194.4 |
System Test |  |  | 118.2 |  |  |  | 73.3 |  |  |  | 44.9 |
Industrial Automation |  |  | 68.7 |  |  |  | 68.9 |  |  |  | (0.2 | )

|  | $ | 819.5 |  |  | $ | 582.0 |  |  | $ | 237.5 |

The increase in Semiconductor Test revenues of $194.4 million, or 48.9%, was driven primarily by an increase in semiconductor mobility test sales resulting from increased complexity of cell phone silicon which drives demand for testers, and an increase in memory test sales of flash and DRAM memory testers. The increase in System Test revenues of $44.9 million, or 61.3%, was primarily due to higher sales in Storage Test of system level and hard disk drive testers, and higher sales in Defense/Aerospace of test instrumentation and systems, partially offset by lower sales in Production Board Test due to lower automotive electronics demand. The decrease in Wireless Test revenues of $1.8 million, or 4.3%, was primarily due to lower demand for millimeter wave test products, partially offset by higher sales in connectivity test products.

Gross Profit
Our gross profit was as follows:

|  | For the Three Months Ended |  |  |  |
|  | September 27, 2020 |  |  | September 29, 2019 |  |  | Dollar/Point Change |
|  | (in millions) |
Gross profit |  | $ | 458.9 |  |  | $ | 345.0 |  |  | $ | 113.9 |
Percent of total revenues |  |  | 56.0 | % |  |  | 59.3 | % |  |  | (3.3 | )

Gross profit as a percent of the revenue decreased by 3.3 points, primarily due to product mix in Semiconductor Test and higher logistic and operations costs due to the
COVID-19
pandemic.
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 September 27, 2020, we recorded an inventory provision of $3.5 million included in cost of revenues primarily due to downward revisions to previously forecasted demand levels, of which $1.8 million was related to Wireless Test and $1.1 million was related to Semiconductor Test.
During the three months ended September 29, 2019, we recorded an inventory provision of $3.0 million included in cost of revenues primarily due to downward revisions to previously forecasted demand levels, of which $1.9 million was related to Semiconductor Test, $0.7 million was related to Wireless Test and $0.4 million was related to System Test.
During the three months ended September 27, 2020 and September 29, 2019, we scrapped $2.4 million and $3.4 million of inventory, respectively. During the three months ended September 27, 2020 and September 29, 2019, we sold $0.3 million and $0.8 million of previously written-down or
written-off
inventory, respectively. As of September 27, 2020, we had reserves for inventory, which had been written-down or
written-off
totaling $108.7 million. We have no
pre-determined
timeline to scrap the remaining inventory.
Selling and Administrative
Selling and administrative expenses were as follows:

|  | For the Three Months Ended |  |  |  |

Percent of total revenues |  |  | 11.6 | % |  |  | 13.4 | % |  |  |  |

The increase of $17.1 million in engineering and development expenses was primarily due to higher variable compensation and higher spending across all segments.
Restructuring and Other
During the three months ended September 27, 2020, we recorded a $27.2 million gain for the decrease in the fair value of the AutoGuide contingent consideration liability, a $1.1 million gain for the decrease in acquisition related compensation liability, partially offset by $0.5 million recorded for employee severance charges primarily in Industrial Automation.
During the three months ended September 29, 2019, we recorded a $7.8 million gain for the decrease in the fair value of the MiR contingent consideration liability, partially offset by $0.5 million recorded for employee severance charges primarily in Industrial Automation and $0.5 million for acquisition related compensation and expenses.
Interest and Other

|  | For the Three Months Ended |  |  |  |

The increase in income before income taxes in Semiconductor Test was driven primarily by an increase in semiconductor mobility test sales resulting from increased complexity of cell phone silicon which drives demand for testers, and an increase in memory test sales of flash and DRAM memory testers. The increase in income before income taxes in System Test was primarily due to higher sales in Storage Test of system level and hard disk drive testers, and higher sales in Defense/Aerospace of test instrumentation and systems, partially offset by lower sales in Production Board Test due to lower automotive electronics demand. The decrease in income before income taxes in Industrial Automation was primarily due to higher engineering and development spending, partially offset by lower intangible assets amortization.
Income Taxes
The effective tax rate for the three months ended September 27, 2020 and September 29, 2019 was 15.6% and 10.5%, respectively. The increase in the effective tax rate from the three months ended September 29, 2019 to the three months ended September 27, 2020 was primarily attributable to an increase in expense related to the international provisions of the U.S. Tax Cuts and Jobs Act of 2017.

|  | $ | 2,362.5 |  |  | $ | 1,640.3 |  |  | $ | 722.2 |

The increase in Semiconductor Test revenues of $622.3 million, or 55.9%, was driven primarily by an increase in semiconductor mobility test sales resulting from increased complexity of cell phone silicon which drives demand for testers, and an increase in memory test sales of flash and DRAM testers. The increase in System Test revenues of $101.2 million, or 49.4%, was primarily due to higher sales in Storage Test of system level and hard disk drive testers, and higher sales in Defense/Aerospace test instrumentation and systems, partially offset by lower sales in Production Board Test due to lower automotive electronics demand. The decrease in Industrial Automation revenues of $22.0 million, or 10.5%, was primarily due to lower demand for collaborative robotic arms in the automotive and manufacturing markets amplified by the impacts of
COVID-19.
The increase in Wireless Test revenues of $20.7 million, or 18.4%, was primarily due to increased sales of 5G and WiFi 6 testers.

During the nine months ended September 27, 2020 and September 29, 2019, we scrapped $5.4 million and $6.4 million of inventory, respectively. During the nine months ended September 27, 2020 and September 29, 2019, we sold $1.7 million and $2.0 million of previously written-down or
written-off
inventory, respectively. As of September 27, 2020, we had inventory related reserves for inventory, which had been written-down or
written-off
totaling $108.7 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 |  |  |  |
|  | September 27, 2020 |  |  | September 29, 2019 |  |  | Dollar Change |
|  | (in millions) |

Percent of total revenues |  |  | 14.4 | % |  |  | 19.5 | % |  |  |  |

The increase of $20.5 million in selling and administrative expenses was primarily due to higher variable compensation.
Engineering and Development
Engineering and development expenses were as follows:

|  | For the Nine Months Ended |  |  |  |
|  | September 27, 2020 |  |  | September 29, 2019 |  |  | Dollar Change |
|  | (in millions) |

Percent of total revenues |  |  | 11.6 | % |  |  | 14.4 | % |  |  |  |

The increase of $38.1 million in engineering and development expenses was primarily due to higher variable compensation and higher spending across all segments.
Restructuring and Other
During the nine months ended September 27, 2020, we recorded a $4.0 million contract termination settlement charge, $3.4 million of acquisition related compensation and expenses, $1.2 million of severance charges primarily in Industrial Automation, and $1.2 million of other expenses, partially offset by a $4.4 million gain for the decrease in the fair value of the AutoGuide contingent consideration liabilities, and a $3.5 million gain for the decrease in the fair value of the MiR contingent consideration liability.
During the nine months ended September 29, 2019, we recorded a $16.5 million gain for the decrease in the fair value of the MiR contingent consideration liability, partially offset by $2.1 million recorded for employee severance charges primarily in Semiconductor Test and Industrial Automation and $2.3 million for acquisition related expenses and compensation.
Interest and Other

|  | For the Nine Months Ended |  |  |  |
|  | September 27, 2020 |  |  | September 29, 2019 |  |  | Dollar Change |
|  | (in millions) |

Other (income) expense, net |  |  | 3.6 |  |  |  | 2.1 |  |  |  | 1.5 |

Interest income decreased by $8.6 million primarily due to lower interest rates in 2020 compared to 2019. Other (income) expense, net increased by $1.5 million primarily due to the change in unrealized gains/losses on equity securities and pension actuarial losses, partially offset by higher realized gains on sales of marketable securities and lower foreign exchange losses.

The increase in income before income taxes in Semiconductor Test was driven primarily by an increase in semiconductor mobility test sales resulting from increased complexity of cell phone silicon which drives demand for testers, and an increase in memory test sales of flash and DRAM testers. The increase in income before income taxes in System Test was primarily due to higher sales in Storage Test of system level and hard disk drive testers, and higher sales in Defense/Aerospace test of instrumentation and systems, partially offset by lower sales in Production Board Test due to lower automotive electronics demand. The increase in Wireless Test income before income taxes was primarily due to increased sales of 5G and WiFi 6 testers. The decrease in income before income taxes in Industrial Automation was primarily due to lower demand for collaborative robotic arms in the automotive and manufacturing markets amplified by the impacts of
COVID-19.
Income Taxes
The effective tax rate for the nine months ended September 27, 2020 and September 29, 2019 was 13.3% and 9.2%, respectively. The increase in the effective tax rate from the nine months ended September 29, 2019 to the nine months ended September 27, 2020 was primarily attributable to a reduction in discrete benefit related to the release of reserves for uncertain tax positions partially offset by an increase in discrete benefit related to the international provisions of the U.S. Tax Cuts and Jobs Act of 2017.

Liquidity and Capital Resources
Our cash, cash equivalents, and marketable securities balances increased by $325.5 million in the nine months ended September 27, 2020 to $1,341.2 million.
Operating activities during the nine months ended September 27, 2020 provided cash of $608.5 million. Changes in operating assets and liabilities used cash of $107.4 million. This was due to a $245.8 million increase in operating assets and a $138.3 million increase in operating liabilities.
The increase in operating assets was due to a $222.0 million increase in accounts receivable due to increased sales, a $40.8 million increase in prepayments and other assets, partially offset by a $17.0 million decrease in inventories.
The increase in operating liabilities was due to a $47.3 million increase in other accrued liabilities, a $36.6 million increase in deferred revenue and customer advance payments, a $24.1 million increase in income taxes, a $23.8 million increase in accounts payable, and a $10.5 million increase in accrued employee compensation, partially offset by $3.9 million of retirement plan contributions.

Financing activities during the nine months ended September 27, 2020 used cash of $143.4 million, due to $88.5 million used for the repurchase of 1.5 million shares of common stock at an average price of $58.33 per share, $49.9 million used for dividend payments, $22.7 million used for payments related to net settlements of employee stock compensation awards, and $8.9 million used for a payment related to MiR acquisition contingent consideration, partially offset by $26.5 million from the issuance of common stock under employee stock purchase and stock option plans.
Operating activities during the nine months ended September 29, 2019 provided cash of $362.4 million. Changes in operating assets and liabilities used cash of $83.5 million due to a $97.1 million increase in operating assets and a $13.6 million increase in operating liabilities.
The increase in operating assets was primarily due to a $66.8 million increase in accounts receivable due to increased sales, a $16.1 million increase in prepayments and other assets, and a $14.1 million increase in inventories.
The increase in operating liabilities was due to a $27.8 million increase in deferred revenue and customer advance payments, a $23.7 million increase in other accrued liabilities, and a $17.5 million increase in accounts payable, partially offset by a $31.2 million decrease in income taxes, a $20.4 million decrease in accrued employee compensation due primarily to first quarter payments related to variable compensation, and $3.8 million of retirement plan contributions.

In January 2020, May 2020 and August 2020, our Board of Directors declared a quarterly cash dividend of $0.10 per share. Dividend payments for the nine months ended September 27, 2020 were $49.9 million.
41

Table of Contents
In January 2019, May 2019 and August 2019, our Board of Directors declared a quarterly cash dividend of $0.09 per share. Dividend payments for the nine months ended September 29, 2019 were $46.3 million.
In January 2020, our Board of Directors cancelled the January 2018 stock repurchase program and approved a new stock repurchase program for up to $1.0 billion of common stock. On April 1, 2020, we suspended the share repurchase program. During the nine months ended September 27, 2020, we repurchased 1.5 million shares of common stock for $88.5 million at an average price of $58.33 per share. During the nine months ended September 29, 2019, we repurchased 8.8 million shares of common stock for $368.8 million at an average price of $41.93 per share.
While we declared a quarterly cash dividend and suspended our share repurchase program, we may reduce or eliminate the cash dividend and may implement a new 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.
On May 1, 2020, we entered into a credit agreement providing for a three-year, senior secured revolving credit facility of $400 million. As of November 2, 2020, we have not borrowed any funds under the credit facility.
We believe our cash, cash equivalents and marketable securities balance will be sufficient to pay our quarterly dividend and meet our working capital and expenditure needs for at least the next twelve months. Inflation has not had a significant long-term impact on earnings. At this time, the
COVID-19
pandemic has not had an impact on our liquidity, but there is no assurance that continued impacts resulting from the pandemic will not have an adverse effect in the future.
Equity Compensation Plans
As discussed in Note L: “Stock Based Compensation” in our 2019 Annual Report on Form
10-K,
we have a 1996 Employee Stock Purchase Plan and a 2006 Equity and Cash Compensation Incentive Plan (the “2006 Equity Plan”).
The purpose of the 1996 Employee Stock Purchase Plan is to encourage stock ownership by all eligible employees of Teradyne. The purpose of the 2006 Equity Plan is to provide equity ownership and compensation opportunities in Teradyne to our employees, officers, directors, consultants and/or advisors. Both plans were approved by our shareholders.
Recently Issued Accounting Pronouncements
In August 2020, the FASB issued ASU
2020-06
– “Debt—Debt with Conversion and Other Options and Derivatives and Hedging - Contracts in Entity’s Own Equity,” which simplifies the accounting for convertible debt instruments by reducing the number of accounting models and the number of embedded conversion features that could be recognized separately from the primary contract. This ASU requires a convertible debt instrument to be accounted for as a single liability measured at its amortized cost, as long as no other features require bifurcation and recognition as derivatives. This ASU requires an entity to use the
if-converted
method in the diluted earnings per share calculation for convertible instruments. This ASU will be effective for Teradyne in on January 1, 2022, with early adoption permitted beginning on January 1, 2021. This ASU permits the use of either the modified retrospective or fully retrospective method of transition. We are evaluating the timing and effects of the adoption of this ASU on our financial statements.

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 2, 2020. There were no material changes in our exposure to market risk from those set forth in our Annual Report on Form
10-K
for the fiscal year ended December 31, 2019.
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 September 27, 2020, the Notes had a fair value of $1,151.5 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 2020 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
42

Table of Contents
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.

Item 4: | Controls and Procedures

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

Item 1: | Legal Proceedings

We are subject to various legal proceedings and claims which have arisen in the ordinary course of business such as, but not limited to, patent, employment, commercial and environmental matters. We believe that we have meritorious defenses against all pending claims and intend to vigorously contest them. While it is not possible to predict or determine the outcomes of any pending claims or to provide possible ranges of losses that may arise, we believe the potential losses associated with all of these actions are unlikely to have a material adverse effect on our business, financial position or results of operations.

Item 1A: | Risk Factors

In addition to other information set forth in this Form
10-Q,
including the risk discussed below, you should carefully consider the factors discussed in Part I, “Item 1A: Risk Factors” in our Annual Report on Form
10-K
for the year ended December 31, 2019, which could materially affect our business, financial condition or future results. The risk factors described in our Annual Report on Form
10-K
remain applicable to our business and many of these risks could be further increased due to the
COVID-19
pandemic.
The risks described in our Annual Report on Form
10-K
are not the only risks that we face. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition and/or operating results.
The novel coronavirus
(COVID-19)
pandemic has impacted our business and could materially adversely affect our results of operations, financial condition, liquidity or cash flows.
The global outbreak of the novel strain of the coronavirus
(COVID-19)
has resulted in government authorities implementing numerous measures in an effort to contain the spread of the virus, such as travel bans and restrictions, limitations on gatherings or social distancing requirements, quarantines,
shelter-in-place
orders, and business limitations and shutdowns. These measures have impacted our
day-to-day
operations and could disrupt our business, workforce and operations, as well as the operations of our
43

Table of Contents
customers, contract manufacturers and suppliers for an uncertain period of time. The
COVID-19
pandemic, and the numerous measures implemented by authorities in response, has adversely impacted our results of operations, including by increasing costs company-wide and decreasing demand in our Industrial Automation businesses, but we cannot accurately estimate the full extent of the impact to our 2020 financial results or to our future financial results.
The
COVID-19
pandemic has significantly increased economic uncertainty in our markets, which could result in a significant decrease in demand for our products for an uncertain period of time. In addition, restrictions on our access to manufacturing facilities or on our support operations or workforce, or similar limitations for our contract manufacturers and suppliers, and restrictions or disruptions affecting transportation, such as reduced availability of transportation and increased border controls or closures, could limit our capacity to meet customer demand, which could have a material adverse effect on our financial condition and results of operations. The spread of
COVID-19
has caused us to modify our business practices, including implementing social distancing protocols, suspending employee travel, requiring most employees to work remotely, canceling physical participation in meetings, events and conferences, and extensively and frequently disinfecting our workspaces, and we may take further actions as may be required by government authorities or that we determine are in the best interests of our employees, customers, contract manufacturers and suppliers. These measures may not be sufficient to mitigate the risks posed by the virus, and our ability to perform critical functions could be harmed. Due to the uncertainty regarding the duration, severity and business impact of the
COVID-19
pandemic, as of April 1, 2020, we have suspended our stock repurchase program announced in January 2020. At this time, we do not know whether or when we will authorize future stock repurchase programs.
We are continuing to monitor the rapidly evolving situation regarding the
COVID-19
pandemic and its impact on our business, results of operations, financial condition, liquidity and cash flows. However, despite careful tracking, we are unable to accurately predict the full impact of
COVID-19,
which will depend on future developments that are highly uncertain and cannot be predicted with accuracy, including, but not limited to, the duration and continued spread of the outbreak, its severity, the actions to contain the virus or treat its impact, and how quickly and to what extent normal economic and operating conditions can resume.
Trade regulations and restrictions could impact our ability to sell products to and support certain customers, which may materially adversely affect our sales and results of operations.
We are subject to U.S. laws and regulations that limit and restrict the export of some of our products and services and may restrict our transactions with certain customers, business partners and other persons. In certain circumstances, export control and economic sanctions regulations may prohibit the export of certain products, services and technologies, and in other circumstances we may be required to obtain an export license before exporting the controlled item. We must also comply with export restrictions and laws imposed by other countries affecting trade and investments. We maintain an export compliance program but there are risks that the compliance controls could be circumvented, exposing us to legal liabilities. Compliance with these laws has not significantly limited our sales but could significantly limit them in the future. Changes in, and responses to, U.S. trade policy could reduce the competitiveness of our products and cause our sales to drop, which could have a material adverse effect on our business, financial condition or results of operations.
The U.S. government from time to time has issued export restrictions that prohibit U.S. companies from exporting U.S. manufactured products, foreign manufactured products with more than 25% controlled U.S. content, as well as U.S. origin technology. For example, the U.S. Department of Commerce has restricted the access of U.S. origin technologies to certain Chinese companies by adding those companies to the Entity List under U.S. Export Administration Regulations (“EAR”).
On May 16, 2019, Huawei and 68 of its affiliates, including HiSilicon, were added to the U.S. Department of Commerce Entity List under the EAR. This action by the U.S. Department of Commerce imposes new export licensing requirements on exports,
re-exports,
and
in-country
transfers of all U.S. regulated products, software and technology to the designated Huawei entities. While most of our products are not subject to the EAR and therefore not affected by the Entity List restrictions, certain of our products are currently manufactured in the U.S. and thus subject to the Entity List restrictions. Compliance with the Entity List restrictions has not significantly impacted our sales. In addition, the prohibition on transfers of U.S. origin technology to Huawei could significantly limit our ability to service certain of our products sold to Huawei and our ability to engage in product development activities with Huawei and, therefore, could have a material adverse effect on our business, financial condition or results of operations. Furthermore, Huawei’s inability to obtain products from other companies in its supply chain may adversely impact Huawei’s demand for our products. Huawei or other foreign customers affected by future U.S. government sanctions or threats of sanctions may respond by developing their own solutions to replace our products or by adopting our foreign competitors’ solutions. Also, our controls related to Entity List compliance could be circumvented, exposing us to legal liabilities. Even if such restrictions are lifted, any financial or other penalties or continuing export restrictions imposed on Huawei could have a material adverse effect on our business, financial condition or results of operations.
44

Table of Contents
On August 17, 2020, the U.S. Department of Commerce published final regulations expanding the scope of the U.S. EAR to include additional products that would become subject to export restrictions relating to Huawei entities including HiSilicon. These new regulations restrict the sale to Huawei and the designated Huawei entities of certain
non-U.S.
made items, such as semiconductor devices, manufactured for or sold to Huawei entities including HiSilicon under specific, detailed conditions set forth in the new regulations. The new regulations also restrict our sales to Huawei, HiSilicon and their suppliers. Because the impact of these new regulations on Huawei’s business is both fluid and uncertain, at this time, we do not know the potential extent of the impact of the new regulations on our business with Huawei entities including HiSilicon and their suppliers. We are taking appropriate actions, including filing for licenses with the U.S. Department of Commerce and working with the U.S. regulators to understand the intended scope of the restrictions. However, we cannot be certain that the actions we take will mitigate all of the risks associated with the new export controls that may impact our business. It is possible that these new regulations and any other additional regulations that may be implemented by the U.S. Department of Commerce or other government agency could have a material impact on our business and financial results.
On April 28, 2020, the U.S. Department of Commerce published new export control regulations for certain U.S. products and technology sold to military end users or for military
end-use
in China, Russia and Venezuela. The definition of military end user is broad. The regulations went into effect on June 29, 2020. We do not expect that compliance with the new export controls will significantly impact our ability to sell products to our customers in China or to manufacture products in China. The new export controls, however, could disrupt our supply chain, increase our compliance costs and impact the demand for our products in China and, thus, have a material adverse impact on our business, financial condition or results of operations. In addition, while we maintain an export compliance program, our compliance controls could be circumvented, exposing us to legal liabilities. We will continue to assess the potential impact of the new export controls on our business and operations and take appropriate actions, including filing for licenses with the U.S. Department of Commerce, to minimize any disruption. However, we cannot be certain that the actions we take will mitigate all of the risks associated with the new export controls that may impact our business.
We have incurred indebtedness and may incur additional indebtedness.
On December 12, 2016, we completed a private offering of $460.0 million aggregate principal amount of 1.25% convertible senior unsecured notes (the “Notes”) due December 15, 2023 and received net proceeds, after issuance costs, of approximately $450.8 million, $33.0 million of which was used to pay the net cost, after being partially offset by proceeds from the sale of the warrants, of the convertible note hedge transactions and $50.1 million of which was used to repurchase 2.0 million shares of our common stock. Holders of the Notes may require us to repurchase the Notes upon the occurrence of certain fundamental changes involving us or the holders may elect to convert into shares of our common stock.
On May 1, 2020, we entered into a three-year, senior secured revolving credit facility of up to $400.0 million. Subject to customary conditions, we may seek to obtain from existing or new lenders incremental commitments under the credit facility in an aggregate principal amount not to exceed $150.0 million. We have not borrowed any funds under this credit facility. We could borrow funds under this credit facility at any time for general corporate purposes and working capital.
The issuance of the Notes and any additional indebtedness, among other things, could:

| • |  | make it difficult to make payments on this indebtedness and our other obligations;

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

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

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

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

In January 2020, our Board of Directors cancelled the January 2018 stock repurchase program and authorized a new stock repurchase program for up to $1.0 billion of common stock. On April 1, 2020, we suspended the stock repurchase program. During the nine months ended September 27, 2020, we repurchased 1.5 million shares of common stock for $88.5 million at an average price of $58.33 per share. During the nine months ended September 29, 2019, we repurchased 8.8 million shares of common stock for $368.8 million at an average price of $41.93 per share.
The following table includes information with respect to repurchases we made of our common stock during the three months ended September 27, 2020 (in thousands except per share price):

(1) | Includes approximately three thousand shares at an average price of $85.00 withheld from employees for the payment of taxes.

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