NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)

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.

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

, 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.

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:

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.
