NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

Note 1.    Nature of Operations and Summary of Significant Accounting Policies

Nature of Operations

Thermo Fisher Scientific Inc. (the company or Thermo Fisher) enables customers to make the world healthier, cleaner and safer by helping them accelerate life sciences research, solve complex analytical challenges, improve patient diagnostics, deliver medicines to market and increase laboratory productivity. Markets served include pharmaceutical and biotech, academic and government, industrial and applied, as well as healthcare and diagnostics.

Interim Financial Statements

The interim consolidated financial statements presented herein have been prepared by the company, are unaudited and, in the opinion of management, reflect all adjustments of a normal recurring nature necessary for a fair statement of the financial position at September 26, 2020, the results of operations for the three- and nine-month periods ended September 26, 2020 and September 28, 2019, and the cash flows for the nine-month periods ended September 26, 2020 and September 28, 2019. Interim results are not necessarily indicative of results for a full year.

The consolidated balance sheet presented as of December 31, 2019, has been derived from the audited consolidated financial statements as of that date. The consolidated financial statements and notes are presented as permitted by Form 10-Q and do not contain all information that is included in the annual financial statements and notes thereto of the company. The consolidated financial statements and notes included in this report should be read in conjunction with the 2019 financial statements and notes included in the company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission (SEC).

Note 1 to the consolidated financial statements for 2019 describes the significant accounting estimates and policies used in preparation of the consolidated financial statements. There have been no material changes in the company’s significant accounting policies during the nine months ended September 26, 2020.

Contract-related Balances

Accounts receivable include amounts that have been billed and are currently due from customers. They are recorded at the invoiced amount and do not bear interest. The company maintains allowances for doubtful accounts for estimates of expected losses resulting from the inability of its customers to pay amounts due. The allowance for doubtful accounts is the company’s best estimate of the amount of probable credit losses in existing accounts receivable. The company determines the allowance based on history of similarly aged receivables, the creditworthiness of the customer, reasons for delinquency, current economic conditions, expectations associated with future events and circumstances where reasonable and supportable forecasts are available and any other information that is relevant to the judgment. Receivables from academic and government customers as well as large, well-capitalized commercial customers have historically experienced less collectability risk. Account balances are charged off against the allowance when the company believes it is probable the receivable will not be recovered. The company does not have any off-balance-sheet credit exposure related to customers.

The changes in the allowance for doubtful accounts are as follows:

	Nine Months Ended
	September 26,		September 28,
(In millions)	2020		2019
Balance at Beginning of Year	$	102	$	117
Cumulative effect of accounting change	1		—
Provision charged to expense	39		19
Accounts written off	(25)		(26)
Acquisitions, currency translation and other	—		(4)
Balance at End of Period	$	117	$	106

Contract assets include revenues recognized in advance of billings and are recorded net of estimated losses resulting from the inability to invoice customers, which is primarily due to risk associated with the company’s performance. Contract assets are classified as current or noncurrent based on the amount of time expected to lapse until the company's right to consideration

becomes unconditional. Noncurrent contract assets are included within other assets in the accompanying balance sheet. Noncurrent contract liabilities are included within other long-term liabilities in the accompanying balance sheet. Contract assets and liabilities are presented on a net basis in the consolidated balance sheet if they arise from different performance obligations in the same contract. Contract asset and liability balances are as follows:

	September 26,		December 31,
(In millions)	2020		2019
Current Contract Assets, Net	$	697	$	603
Noncurrent Contract Assets, Net	11		17
Current Contract Liabilities	1,047		916
Noncurrent Contract Liabilities	674		594

In the three and nine months ended September 26, 2020, the company recognized revenues of $142 million and $773 million, respectively, that were included in the contract liabilities balance at December 31, 2019.

Finished Goods	2,024		1,882

Use of Estimates

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period.

The company’s estimates include, among others, asset reserve requirements as well as the amounts of future cash flows associated with certain assets and businesses that are used in assessing the risk of impairment. Risks and uncertainties associated with the ongoing COVID-19 global pandemic have and will continue to materially adversely affect certain of the company’s businesses, particularly in the Analytical Instruments segment and, to a lesser extent, in some businesses within the other three segments, through at least the fourth quarter of 2020. The extent and duration of such impacts are uncertain and may require changes to estimates. Actual results could differ from those estimates.

Recent Accounting Pronouncements

In January 2020, the FASB issued new guidance to clarify the interaction of the accounting for certain equity securities, equity method investments, and certain forward contracts and purchased options. Among other things, the new guidance clarifies that an entity should consider observable transactions that require it to either apply or discontinue the equity method of accounting for the purposes of applying measurement principles for certain equity securities immediately before applying or discontinuing the equity method. The company adopted this guidance in 2020 using a prospective method. The adoption of this guidance did not have a material impact on the company’s consolidated financial statements.

In December 2019, the FASB issued new guidance to simplify the accounting for income taxes. Among other things, the new guidance requires the effects of enacted changes in tax laws or rates to be reflected in the annual effective tax rate computation in the interim period that includes the enactment date. The company expects to adopt this guidance when it is effective in 2021 using a prospective method. The adoption of this guidance is not expected to have a material impact on the company’s consolidated financial statements; however, the impact in future periods will be dependent on the extent of future events or conditions that would be affected such as enacted changes in tax laws or rates.

In August 2018, the FASB issued new guidance to modify the disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. The company adopted the guidance in 2020 using a retrospective method. The adoption of this guidance did not have a material impact on the company’s disclosures.

In August 2018, the FASB issued new guidance to modify the disclosure requirements on fair value measurements. The company adopted the guidance in 2020 with some items requiring a prospective method and others requiring a retrospective method. The adoption of this guidance did not have a material impact on the company’s disclosures.

In June 2016, the FASB issued new guidance to require a financial asset measured at amortized cost basis, such as accounts receivable, to be presented at the net amount expected to be collected based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. During 2018 and 2019, the FASB issued additional guidance and clarification. The company adopted the guidance in 2020 using a modified retrospective method. The adoption of this guidance reduced accounts receivable and retained earnings by $1 million on January 1, 2020.

Note 2.    Acquisitions and Dispositions

The company’s acquisitions have historically been made at prices above the determined fair value of the acquired identifiable net assets, resulting in goodwill, primarily due to expectations of the synergies that will be realized by combining the businesses. These synergies include the elimination of redundant facilities, functions and staffing; use of the company’s existing commercial infrastructure to expand sales of the acquired businesses’ products; and use of the commercial infrastructure of the acquired businesses to cost-effectively expand sales of company products.

Acquisitions have been accounted for using the acquisition method of accounting, and the acquired companies’ results have been included in the accompanying financial statements from their respective dates of acquisition. Acquisition transaction costs are recorded in selling, general and administrative expenses as incurred.

Terminated Acquisition

As previously announced, on March 3, 2020, the company entered into a purchase agreement to acquire all of the issued and outstanding shares of QIAGEN N.V. (“QIAGEN”). Following a determination that the number of shares tendered by QIAGEN shareholders did not meet the minimum amount required for the transaction to proceed, on August 13, 2020, the company delivered to QIAGEN a written notice terminating the purchase agreement in accordance with the terms of the agreement. In connection with the termination, QIAGEN paid to the company an expense reimbursement payment of $95 million in cash which has been recorded as a reduction of selling, general and administrative expenses.

Disposition

On June 28, 2019, the company sold its Anatomical Pathology business to PHC Holdings Corporation for $1.13 billion, net of cash divested. The business was part of the Specialty Diagnostics segment.

Provision for Income Taxes	$	456		$	338

The company has operations and a taxable presence in approximately 50 countries outside the U.S. The company's effective income tax rate differs from the U.S. federal statutory rate each year due to certain operations that are subject to tax incentives, state and local taxes, and foreign taxes that are different than the U.S. federal statutory rate.

In the second quarter of 2020, the company implemented foreign tax credit planning in Sweden which resulted in $96 million of foreign tax credits, with no related incremental U.S. income tax expense.

Unrecognized Tax Benefits

As of September 26, 2020, the company had $1.51 billion of unrecognized tax benefits substantially all of which, if recognized, would reduce the effective tax rate.

A reconciliation of the beginning and ending amounts of unrecognized tax benefits is as follows:

Credit Facilities

The company has a revolving credit facility, as amended, (the Facility) with a bank group that provides for up to $2.5 billion of unsecured multi-currency revolving credit. The Facility expires in July 2022. The revolving credit agreement calls for interest at either a LIBOR-based rate, a EURIBOR-based rate (for funds drawn in euro) or a rate based on the prime lending rate of the agent bank, at the company’s option. The agreement contains affirmative, negative and financial covenants, and events of default customary for facilities of this type. The covenants in the Facility include a Consolidated Leverage Ratio (net debt-to-Consolidated EBITDA) and a Consolidated Interest Coverage Ratio (Consolidated EBITDA to Consolidated Interest Expense), as such terms are defined in the Facility. Specifically, the company has agreed that, so long as any lender has any commitment under the Facility, any letter of credit is outstanding under the Facility, or any loan or other obligation is outstanding under the Facility, it will maintain a maximum Consolidated Leverage Ratio of 5.0:1.0, with such ratio stepping down to 4.0 to 1.0 for the two consecutive fiscal quarters starting on the last day of the first fiscal quarter of 2022 and then stepping down to 3.5 to 1.0 for each fiscal quarter ending thereafter. The company has also agreed that so long as any lender has any commitment under the Facility or any letter of credit is outstanding under the Facility, or any loan or other obligation is outstanding under the Facility, it will maintain a minimum Consolidated Interest Coverage Ratio of 3.0:1.0 as of the last day of any fiscal quarter. As of September 26, 2020, no borrowings were outstanding under the Facility, although available capacity was reduced by approximately $66 million as a result of outstanding letters of credit.

Commercial Paper Programs

The company has commercial paper programs pursuant to which it may issue and sell unsecured, short-term promissory notes (CP Notes). Under the U.S. program, a) maturities may not exceed 397 days from the date of issue and b) the CP Notes are issued on a private placement basis under customary terms in the commercial paper market and are not redeemable prior to maturity nor subject to voluntary prepayment. Under the euro program, maturities may not exceed 183 days and may be denominated in euro, U.S. dollars, Japanese yen, British pounds sterling, Swiss franc, Canadian dollars or other currencies. Under both programs, the CP Notes are issued at a discount from par (or premium to par, in the case of negative interest rates), or, alternatively, are sold at par and bear varying interest rates on a fixed or floating basis. As of September 26, 2020, there were no outstanding borrowings under these programs.

Senior Notes

Interest is payable annually on the euro-denominated senior notes and semi-annually on all other senior notes. Each of the notes may be redeemed at a redemption price of 100% of the principal amount plus a specified make-whole premium and accrued interest. The company is subject to certain affirmative and negative covenants under the indentures governing the senior notes, the most restrictive of which limits the ability of the company to pledge principal properties as security under borrowing arrangements.

Interest Rate Swap Arrangements and related Cross-currency Interest Rate Swap Arrangements

The company has entered into LIBOR-based interest rate swap arrangements with various banks. The aggregate amounts of the swaps are equal to the principal amount of the notes and the payment dates of the swaps coincide with the interest payment dates of the note. The swap contracts provide for the company to pay a variable interest rate and receive a fixed rate. The variable interest rates reset monthly. The swaps have been accounted for as fair value hedges of the notes. See Note 10 for additional information on the interest rate swap arrangements and related cross-currency interest rate swap arrangements. The following table summarizes the outstanding interest rate swap arrangements on the company's senior notes at September 26, 2020:

	Aggregate Notional Amount		Pay Rate as of
(Dollars in millions)		Pay Rate	September 26, 2020		Receive Rate
3.00% Senior Notes due 2023 (a)	1,000	1-month LIBOR + 1.7640%	1.9164	%	3.00	%

(a) The payments on $900 million notional value of these interest rate swaps are offset in part by cross-currency interest rate swaps which effectively reduced the pay rate as of September 26, 2020 from 1.92% to a weighted average of 1.13%.

The company has entered into $900 million notional value of cross-currency interest rate swaps, which effectively convert a portion of the semi-annual payments related to the variable rate, U.S. dollar denominated, LIBOR-based interest rate swaps to payments on variable rate, euro denominated, EURIBOR-based cross-currency interest rate swaps.

Note 8.    Commitments and Contingencies

Environmental Matters

The company is currently involved in various stages of investigation and remediation related to environmental matters. The company cannot predict all potential costs related to environmental remediation matters and the possible impact on future operations given the uncertainties regarding the extent of the required cleanup, the complexity and interpretation of applicable laws and regulations, the varying costs of alternative cleanup methods and the extent of the company’s responsibility. Expenses for environmental remediation matters related to the costs of installing, operating and maintaining groundwater-treatment systems and other remedial activities related to historical environmental contamination at the company’s domestic and international facilities were not material in any period presented. The company records accruals for environmental remediation liabilities, based on current interpretations of environmental laws and regulations, when it is probable that a liability has been incurred and the amount of such liability can be reasonably estimated. The company calculates estimates based upon several factors, including input from environmental specialists and management’s knowledge of and experience with these environmental matters. The company includes in these estimates potential costs for investigation, remediation and operation and maintenance of cleanup sites. At September 26, 2020, the company’s total environmental liability was approximately $70 million. While management believes the accruals for environmental remediation are adequate based on current estimates of remediation costs, the company may be subject to additional remedial or compliance costs due to future events such as changes in existing laws and regulations, changes in agency direction or enforcement policies, developments in remediation technologies or changes in the conduct of the company’s operations, which could have a material adverse effect on the company’s financial position, results of operations or cash flows.

Litigation and Related Contingencies

There are various lawsuits and claims pending against the company including matters involving product liability, intellectual property, employment and commercial issues. The company determines the probability and range of possible loss based on the current status of each of these matters. A liability is recorded in the financial statements if it is believed to be probable that a loss has been incurred and the amount of the loss can be reasonably estimated. The company establishes a liability that is an estimate of amounts expected to be paid in the future for events that have already occurred. The company accrues the most likely amount or at least the minimum of the range of probable loss when a range of probable loss can be estimated. The accrued liabilities are based on management’s judgment as to the probability of losses for asserted and unasserted claims and, where applicable, actuarially determined estimates. Accrual estimates are adjusted as additional information becomes known or payments are made. The amount of ultimate loss may differ from these estimates. Due to the inherent uncertainties associated with pending litigation or claims, the company cannot predict the outcome, nor, with respect to certain pending litigation or claims where no liability has been accrued, make a meaningful estimate of the reasonably possible loss or range of loss that could result from an unfavorable outcome. The company has no material accruals for pending litigation or claims for which accrual amounts are not disclosed below or in the company's 2019 financial statements and notes included in the company's Annual Report on Form 10-K filed with the SEC, nor are material losses deemed probable for such matters. It is reasonably possible, however, that an unfavorable outcome that exceeds the company’s current accrual estimate, if any, for one or more of the matters described below could have a material adverse effect on the company’s results of operations, financial position and cash flows.

Product Liability, Workers Compensation and Other Personal Injury Matters

For product liability, workers compensation and other personal injury matters, the company accrues the most likely amount or at least the minimum of the range of possible loss when a range of possible loss can be estimated. The company records estimated amounts due from insurers related to certain product liabilities as an asset. Although the company believes that the amounts accrued and estimated recoveries are probable and appropriate based on available information, including actuarial studies of loss estimates, the process of estimating losses and insurance recoveries involves a considerable degree of judgment by management and the ultimate amounts could vary materially. Insurance contracts do not relieve the company of its primary obligation with respect to any losses incurred. The collectability of amounts due from its insurers is subject to the solvency and willingness of the insurer to pay, as well as the legal sufficiency of the insurance claims. Management monitors the payment history as well as the financial condition and ratings of its insurers on an ongoing basis.

Intellectual Property Matters

On June 3, 2013, Unisone Strategic IP filed a complaint against Life Technologies, a subsidiary of the company, in the United States District Court for the Southern District of California alleging patent infringement by Life Technologies’ supply chain management system software, which operates with product “supply centers” installed at customer sites. Plaintiff sought damages for alleged willful infringement, attorneys’ fees, costs, and injunctive relief. On September 30, 2020, this matter was settled by payment of a nominal amount by the company.

Strategic Partnership and Long-term Lease

In May 2020, the company entered a strategic partnership with CSL Limited (CSL). Through a long-term lease agreement with CSL, the company will operate a new state-of-the-art biologics manufacturing facility in Lengnau, Switzerland, when construction is completed in mid-2021, to perform pharma services for CSL with capacity to serve other customers as well. The company made an initial lease payment of $50 million in the second quarter of 2020 (included within other assets in the accompanying balance sheet) and expects to make additional fixed lease payments aggregating to $555 million (excluding renewals) from 2021 to 2041, with additional amounts dependent on the extent of revenues from customers of the facility other than CSL.

Loss on Supply Agreement

The Analytical Instruments segment recorded a charge to cost of product revenues for $108 million in the third quarter of 2020 related to an existing supply contract for components of electron microscopy instruments. The agreement requires the company to make future minimum purchases through 2025. The company has developed and launched an alternative product beginning in 2020 and based on the expected demand for the internally developed product vs. the third-party product, the company does not expect to use all of the product it will be required to buy, resulting in a loss on the purchase commitment.

The company uses the Black-Scholes model to value its warrants. The company determines the fair value of its insurance contracts by obtaining the cash surrender value of the contracts from the issuer. The fair value of derivative contracts is the estimated amount that the company would receive/pay upon liquidation of the contracts, taking into account the change in interest rates and currency exchange rates. The company determines the fair value of acquisition-related contingent consideration based on the probability-weighted discounted cash flows associated with such future payments. Changes to the

Gains and losses recognized on currency exchange contracts and the interest rate swaps designated as fair value hedges are included in the consolidated statement of income together with the corresponding, offsetting losses and gains on the underlying hedged transactions.

The company also uses foreign currency-denominated debt and cross-currency interest rate swaps to partially hedge its net investments in foreign operations against adverse movements in exchange rates. The majority of the company’s euro-denominated senior notes and certain of its cross-currency interest rate swaps have been designated as, and are effective as, economic hedges of part of the net investment in a foreign operation. Accordingly, foreign currency transaction gains or losses due to spot rate fluctuations on the euro-denominated debt instruments and contract fair value changes on the cross-currency

interest rate swaps, excluding interest accruals, are included in currency translation adjustment within other comprehensive items and shareholders’ equity.

The company also had $1 billion notional value of cross currency swaps which the company terminated in October 2020. These swaps were entered into in anticipation of using U.S. dollars to partially finance the euro purchase price of the terminated QIAGEN acquisition (Note 2). Gains and losses associated with these swaps were recorded in other expense, net.

See Note 1 to the consolidated financial statements for 2019 included in the company's Annual Report on Form 10-K and Note 7 herein for additional information on the company's risk management objectives and strategies.

Cash Flow Hedge Arrangements

In March 2020, the company entered into interest rate swap arrangements to mitigate the risk of interest rates rising prior to completion of future debt offerings. Based on the company's conclusion that the debt offerings are probable, the swaps hedge the cash flow risk for each of the interest payments on the planned fixed-rate debt issues. One of these hedges was terminated in March 2020, in connection with the debt offering completed in that month. The remaining hedges were terminated in July 2020. The aggregate fair value of the terminated hedges, net of tax, has been classified as a reduction to accumulated other comprehensive items and will be amortized to interest expense over the term of the related debt issuances. The company had cash outlays aggregating $85 million in 2020 associated with termination of the arrangements, included in other financing activities, net, in the accompanying statement of cash flows.

Note 12.    Restructuring and Other Costs (Income), Net

In the first nine months of 2020 the company recorded transaction/integration costs (including reimbursement thereof) related to recent/terminated acquisitions, continuing charges for headcount reductions and facility consolidations in an effort to streamline operations, and, to a lesser extent, impairment of acquired technology in development and non-cash charges for writedowns of fixed assets to estimated disposal value in connection with the consolidation of commercial production operations in the U.S. In the first nine months of 2020, severance actions associated with facility consolidations and cost reduction measures affected less than 1% of the company’s workforce.

As of October 30, 2020, the company has identified restructuring actions that will result in additional charges of approximately $45 million, primarily in 2020 and 2021, and expects to identify additional actions during 2020 which will be recorded when specified criteria are met, such as communication of benefit arrangements or when the costs have been incurred.

Item 2.    Management’s Discussion and Analysis of Financial Condition and Results of Operations

Forward-looking statements, within the meaning of Section 21E of the Securities Exchange Act of 1934 are made throughout this Management’s Discussion and Analysis of Financial Condition and Results of Operations. Any statements contained herein that are not statements of historical fact may be deemed to be forward-looking statements, including without limitation statements regarding: projections of revenues, expenses, earnings, margins, tax rates, tax provisions, cash flows, pension and benefit obligations and funding requirements, our liquidity position; cost reductions, restructuring activities, new product and service developments, competitive strengths or market position, acquisitions or divestitures; growth, declines and other trends in markets we sell into; new or modified laws, regulations and accounting pronouncements; outstanding claims, legal proceedings, tax audits and assessments and other contingent liabilities; foreign currency exchange rates and fluctuations in those rates; general economic and capital markets conditions; the timing of any of the foregoing; assumptions underlying any of the foregoing; the expected impact of the COVID-19 pandemic on the company’s business; and any other statements that address events or developments that Thermo Fisher intends or believes will or may occur in the future. Without limiting the foregoing, the words “believes,” “anticipates,” “plans,” “expects,” “seeks,” “estimates,” and similar expressions are intended to identify forward-looking statements, although not all forward-looking statements are accompanied by such words. While the company may elect to update forward-looking statements in the future, it specifically disclaims any obligation to do so, even if the company’s estimates change, and readers should not rely on those forward-looking statements as representing the company’s views as of any date subsequent to the date of the filing of this Quarterly Report.

Important factors that could cause actual results to differ materially from those indicated by such forward-looking statements are set forth under the caption “Risk Factors” in the company’s Annual Report on Form 10-K for the year ended December 31, 2019 (which is on file with the SEC), as updated i) by the company’s Quarterly Report on Form 10-Q for the quarter ended June 27, 2020 (which is on file with the SEC), and ii) under the heading “Risk Factors” in Part II, Item 1A of this report on Form 10-Q. Important factors that could cause actual results to differ materially from those indicated by forward-looking statements include risks and uncertainties relating to: the duration and severity of the COVID-19 pandemic; the need to develop new products and adapt to significant technological change; implementation of strategies for improving growth; general economic conditions and related uncertainties, dependence on customers' capital spending policies and government funding policies; the effect of economic and political conditions and exchange rate fluctuations on international operations; use and protection of intellectual property; the effect of changes in governmental regulations; and the effect of laws and regulations governing government contracts, as well as the possibility that expected benefits related to recent or pending acquisitions may not materialize as expected.

Overview

The company develops, manufactures and sells a broad range of products that are sold worldwide. The company expands the product lines and services it offers by developing and commercializing its own technologies and by making strategic acquisitions of complementary businesses. The company’s operations fall into four segments (Note 4): Life Sciences Solutions, Analytical Instruments, Specialty Diagnostics and Laboratory Products and Services.

The company has mobilized to support the global novel strain of coronavirus (COVID-19) response with products and services that help analyze, diagnose and protect from the virus. However, as the pandemic spread from China to countries worldwide, the company saw a significant reduction in customer activity in several businesses by late March and continuing into the fourth quarter of 2020 that will materially adversely affect primarily the results of the Analytical Instruments segment and, to a lesser extent, some businesses within the company’s other three segments, at least through the fourth quarter of 2020. The extent and duration of the negative impacts are uncertain and dependent in part on customers continuing to return to work and economic activity ramping up. The company believes the impacted businesses’ long-term prospects remain excellent given the company’s attractive markets served, its industry-leading position and proven growth strategy. Several of the company’s businesses have had a significant increase in revenues due to sales of product and services addressing diagnosis and treatment of COVID-19, including test kits and, to a lesser extent, products and services for therapy and vaccine development and manufacturing. While these positive impacts are expected to continue into the fourth quarter of 2020, the duration and extent of future revenues from such sales are uncertain and dependent primarily on customer testing demand.

Recent Acquisitions and Divestitures

The company’s strategy is to augment internal growth at existing businesses with complementary acquisitions. The company’s principal recent acquisitions and divestitures are described below.

On April 30, 2019, the company acquired, within the Laboratory Products and Services segment, Brammer Bio for approximately $1.67 billion in cash. Brammer Bio is a leading viral vector contract development and manufacturing organization for gene and cell therapies. The acquisition expands the segment’s contract manufacturing capabilities. Brammer Bio reported revenues of approximately $140 million in 2018.

On June 28, 2019, the company sold its Anatomical Pathology business to PHC Holdings Corporation for $1.13 billion, net of cash divested. The business was part of the Specialty Diagnostics segment. Revenues in 2019, through the date of sale, and the full year 2018 of the business sold were approximately $115 million and $238 million, respectively, net of retained sales through the company's healthcare market and research and safety market channel businesses.

Sales in the third quarter of 2020 were $8.52 billion, an increase of $2.25 billion from 2019. The favorable effects of currency translation resulted in an increase in revenues of $80 million in the third quarter of 2020. Sales increased $32 million due to an acquisition. Aside from the effects of currency translation and acquisitions, revenues increased $2.14 billion (34%) primarily due to increased demand in the quarter compared to the 2019 quarter. Sales were particularly strong in diagnostic and healthcare markets, primarily due to demand for products supporting customers diagnosing the COVID-19 virus, as well as to customers in pharma and biotech markets where demand was strong for products and services and pandemic-related demand for therapies and vaccines also contributed to growth. Sales to academic and government customers grew modestly. Sales to customers in industrial markets decreased primarily due to lower demand from weakened economic conditions related to COVID-19. Sales growth was strong in each of the company’s primary geographic areas during the third quarter of 2020.

In the third quarter of 2020, total company operating income and operating income margin were $2.43 billion and 28.5%, respectively, compared with $0.95 billion and 15.1%, respectively, in 2019. The increase in operating income was primarily due to profit on higher sales and, to a lesser extent, sales mix, offset in part by strategic growth investments in 2020. The company’s references to strategic growth investments generally refer to targeted spending for enhancing commercial capabilities, including expansion of geographic sales reach and e-commerce platforms, marketing initiatives, expanded service and operational infrastructure, focused research projects and other expenditures to enhance the customer experience, as well as incentive compensation and recognition for employees. The company’s references throughout this discussion to productivity improvements generally refer to improved cost efficiencies from its Practical Process Improvement (PPI) business system, reduced costs resulting from global sourcing initiatives, a lower cost structure following restructuring actions, including headcount reductions and consolidation of facilities, and low cost region manufacturing. Productivity improvements are calculated net of inflationary cost increases.

The company's effective tax rate was 14.2% for the third quarter of 2020. The company expects its effective tax rate for all of 2020 will be between 10% and 12% based on currently forecasted rates of profitability in the countries in which the company conducts business and expected generation of foreign tax credits. Due primarily to the non-deductibility of intangible asset amortization for tax purposes, the company’s cash payments for income taxes are higher than its income tax expense for

financial reporting purposes and are expected to total $1.20 to $1.23 billion in 2020. In the third quarter of 2019, the company’s effective tax rate was 7.6%.

Net income increased to $1.93 billion in the third quarter of 2020 from $0.76 billion in the third quarter of 2019, primarily due to the increase in operating income in the 2020 period (discussed above), offset in part by the increase in the income tax provision.

During the first nine months of 2020, the company’s cash flow from operations totaled $4.95 billion compared with $3.06 billion for 2019. The increase primarily resulted from higher cash provided by income and, to a lesser extent, lower investment in working capital in 2020.

As of September 26, 2020, the company’s short-term debt totaled $2 million. The company has a revolving credit facility with a bank group that provides up to $2.5 billion of unsecured multi-currency revolving credit (Note 7). If the company borrows under this facility, it intends to leave undrawn an amount equivalent to outstanding commercial paper to provide a source of funds in the event that commercial paper markets are not available. As of September 26, 2020, no borrowings were outstanding under the company’s revolving credit facility, although available capacity was reduced by approximately $66 million as a result of outstanding letters of credit.

The company believes that its existing cash and cash equivalents of $7.54 billion as of September 26, 2020 and its future cash flow from operations together with available borrowing capacity under its revolving credit agreement will be sufficient to meet the cash requirements of its existing businesses for the foreseeable future, including at least the next 24 months.

Critical Accounting Policies and Estimates

The company’s discussion and analysis of its financial condition and results of operations is based upon its financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of these financial statements requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses and related disclosure of contingent liabilities. On an on-going basis, management evaluates its estimates, including those related to intangible assets and goodwill, income taxes and contingencies and litigation. Management believes the most complex and sensitive judgments, because of their significance to the consolidated financial statements, result primarily from the need to make estimates about the effects of matters that are inherently uncertain. Management bases its estimates on historical experience, current market and economic conditions and other assumptions that management believes are reasonable. The results of these estimates form the basis for judgments about the carrying value of assets and liabilities where the values are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. Management’s Discussion and Analysis and Note 1 to the Consolidated Financial Statements of the company’s Form 10-K for 2019, describe the significant accounting estimates and policies used in preparation of the consolidated financial statements. There have been no significant changes in the company's critical accounting policies during the first nine months of 2020.

Sales in the third quarter of 2020 were $8.52 billion, an increase of $2.25 billion from the third quarter of 2019. The favorable effects of currency translation resulted in an increase in revenues of $80 million in 2020. Sales increased $32 million due to an acquisition. Aside from the effects of currency translation and acquisitions, revenues increased $2.14 billion (34%) primarily due to increased demand in the quarter compared to the 2019 quarter. Sales were particularly strong in diagnostic and healthcare markets, primarily due to demand for products supporting customers diagnosing the COVID-19 virus, as well as to customers in pharma and biotech markets where demand was strong for products and services and pandemic-related demand for therapies and vaccines also contributed to growth. Sales to academic and government customers grew modestly. Sales to customers in industrial markets decreased primarily due to lower demand from weakened economic conditions related to COVID-19. Sales growth was strong in each of the company’s primary geographic areas during the third quarter of 2020.

In the third quarter of 2020, total company operating income and operating income margin were $2.43 billion and 28.5%, respectively, compared with $0.95 billion and 15.1%, respectively, in 2019. The increase in operating income was primarily due to profit on higher sales and, to a lesser extent, sales mix, offset in part by strategic growth investments in 2020.

In the third quarter of 2020, the company recorded restructuring and other income, net, of $37 million, including $55 million of net credits to selling, general and administrative expenses, principally third-party transaction and integration-related costs (including reimbursement thereof) for recent and terminated acquisitions and changes in estimates of contingent acquisition consideration. In addition, the company recorded $17 million of restructuring and other charges, net, for impairment of acquired technology in development, and, to a lesser extent, employee severance and other costs associated with facility consolidations/abandonments in efforts to streamline operations. See Note 12 for restructuring charges expected in future periods.

In the third quarter of 2019, the company recorded restructuring and other costs, net, of $43 million, including $19 million of net charges associated with sales of businesses in prior periods, including post-closing adjustments. The company recorded $5 million of charges to cost of revenues for the sale of inventories revalued at the date of acquisition. The company also recorded $7 million of charges to selling, general and administrative expenses, principally transaction and integration-related costs for recent acquisitions. In addition, the company recorded $12 million of cash restructuring charges, primarily for employee severance and abandoned facilities costs associated with the closure and consolidation of facilities in the U.S. and Europe.

Segment Results

The company’s management evaluates segment operating performance using operating income before certain charges/credits to cost of revenues and selling, general and administrative expenses, principally associated with acquisition-related activities; restructuring and other costs/income including costs arising from facility consolidations such as severance and abandoned lease expense and gains and losses from the sale of real estate and product lines; and amortization of acquisition-related intangible assets. The company uses this measure because it helps management understand and evaluate the segments’ core operating results and facilitate comparison of performance for determining compensation (Note 4). Accordingly, the following segment data is reported on this basis.

Operating Income Margin	54.9		%	34.5		%	20.4 pt

Sales in the Life Sciences Solutions segment increased $1.72 billion to $3.42 billion in the third quarter of 2020. Sales increased $1.70 billion (100%) due to higher revenues at existing businesses. The favorable effects of currency translation resulted in an increase in revenues of $20 million. The increase in revenues at existing businesses was primarily driven by demand for testing to diagnose COVID-19 with higher sales of genetic sciences products and, to a lesser extent, bioscience products. Sales also grew due to higher demand for bioproduction products.

Operating income margin was 54.9% in the third quarter of 2020 compared to 34.5% in the third quarter of 2019. The increase resulted primarily from profit on higher sales and, to a lesser extent, sales mix, offset in part by strategic growth investments.

Sales in the Analytical Instruments segment decreased $22 million to $1.34 billion in the third quarter of 2020. Sales decreased $41 million (-3%) due to lower revenues at existing businesses. The favorable effects of currency translation resulted in an increase in revenues of $19 million. The decrease in revenues at existing businesses was primarily the result of weakened economic conditions due to COVID-19 and lower sales to academic customers due to pandemic-related conditions. The contraction in sales to these customers improved significantly from the decrease reported in the second quarter of 2020.

Operating income margin was 12.8% in the third quarter of 2020 compared to 23.0% in the third quarter of 2019. The decrease was primarily due to a $108 million charge related to a long-term supply contract (discussed in Note 8) and, to a lesser extent, sales mix and strategic growth investments, offset in part by productivity improvements.

Sales in the Specialty Diagnostics segment increased $551 million to $1.43 billion in the third quarter of 2020. Sales increased $541 million (62%) due to higher revenues at existing businesses. The favorable effects of currency translation resulted in an increase in revenues of $10 million. The increase in revenues at existing businesses was due to higher demand primarily driven by products addressing treatment of COVID-19, with particular strength in sales of products sold through the segment's healthcare market channel business, and to a lesser extent, microbiology and clinical diagnostics products.

Operating income margin was 27.9% in the third quarter of 2020 and 25.3% in the third quarter of 2019. The increase was primarily due to profit on higher sales, offset in part by sales mix and, to a lesser extent, strategic growth investments.

Sales in the Laboratory Products and Services segment increased $493 million to $3.11 billion in the third quarter of 2020. Sales increased $428 million (16%) due to higher revenues at existing businesses and $32 million due to an acquisition. The favorable effects of currency translation resulted in an increase in revenues of $33 million. The increase in revenues at existing businesses was primarily due to increased sales in the segment's research and safety market channel business, pharma services business and laboratory products business.

Operating income margin was 11.4% in the third quarter of 2020 and 11.6% in the third quarter of 2019. The decrease was primarily due to sales mix and strategic growth investments, offset in part by profit on higher sales and, to a lesser extent, productivity improvements.

Other Expense, Net

The company reported other expense, net of $39 million in the third quarter of 2020 compared to $12 million in the third quarter of 2019. In 2020, other expense, net includes $37 million of costs for the terminated QIAGEN acquisition, primarily for amortization of loan commitment fees. In 2019, other expense, net includes $42 million of losses on the early extinguishment of debt.

Provision for Income Taxes

The company's effective tax rate was 14.2% for the third quarter of 2020. The company expects its effective tax rate for all of 2020 will be between 10% and 12% based on currently forecasted rates of profitability in the countries in which the company conducts business and expected generation of foreign tax credits. Due primarily to the non-deductibility of intangible asset amortization for tax purposes, the company’s cash payments for income taxes are higher than its income tax expense for financial reporting purposes and are expected to total $1.20 to $1.23 billion in 2020. In the third quarter of 2019, the company’s effective tax rate was 7.6%.

The company has operations and a taxable presence in approximately 50 countries outside the U.S. Some of these countries have lower tax rates than the U.S. The company’s ability to obtain a benefit from lower tax rates outside the U.S. is dependent on its relative levels of income in countries outside the U.S. and on the statutory tax rates in those countries. Based on the dispersion of the company’s non-U.S. income tax provision among many countries, the company believes that a change in the statutory tax rate in any individual country is not likely to materially affect the company’s income tax provision or net income, aside from any resulting one-time adjustment to the company’s deferred tax balances to reflect a new rate.

Sales in the first nine months of 2020 were $21.67 billion, an increase of $2.96 billion from the first nine months of 2019. Sales increased $73 million due to acquisitions, net of a divestiture. The unfavorable effects of currency translation resulted in a decrease in revenues of $67 million in 2020. Aside from the effects of currency translation and acquisitions/divestiture, revenues increased $2.95 billion (16%) primarily due to increased demand. Sales were particularly strong in diagnostic and healthcare markets, primarily due to demand for products supporting customers diagnosing the COVID-19 virus, as well as to customers in pharma and biotech markets where demand was strong for products and services and pandemic-related demand for therapies and vaccines also contributed to growth. Sales to academic and government customers decreased due primarily to closure of academic labs during the global pandemic. Sales to customers in industrial markets decreased primarily due to lower demand from weakened economic conditions related to COVID-19. Sales growth was particularly strong in North America and Europe while sales grew modestly in the Asia-Pacific region.

In the first nine months of 2020, total company operating income and operating income margin were $4.72 billion and 21.8%, respectively, compared with $3.36 billion and 18.0%, respectively, in the first nine months of 2019. The increase in operating income was primarily due to profit on higher sales and, to a lesser extent, sales mix, offset in part by the gain on the sale of the Anatomical Pathology business included in the 2019 period and, to a lesser extent, strategic growth investments in 2020.

In the first nine months of 2020, the company recorded restructuring and other costs, net, of $65 million (Note 12). The company recorded $5 million of charges to cost of revenues for accelerated depreciation on fixed assets to be disposed of in connection with the consolidation of commercial production operations in the U.S., as well as charges to conform the accounting policies of a recently acquired business with the company’s accounting policies. The company recorded $7 million of net credits to selling, general and administrative expenses, principally transaction and integration-related costs (and reimbursement thereof) for recent and terminated acquisitions, as well as income for changes in estimates of contingent acquisition consideration. In addition, the company recorded $43 million of cash restructuring charges, net, primarily for employee severance and abandoned facilities costs associated with the closure and consolidation of facilities in Europe, and the U.S. The company also recorded $24 million of charges for impairment of acquired technology in development, writedowns of fixed assets to estimated disposal value in connection with the consolidation of commercial production operations in the U.S. and, to a lesser extent, environmental remediation charges for abandoned and previously owned facilities.

In the first nine months of 2019, the company recorded restructuring and other income, net, of $372 million, including $482 million of net gains on the sale of businesses, principally the Anatomical Pathology business. The company also recorded $16 million of charges to cost of revenues for the sale of inventories revalued at the date of acquisition, and $54 million of net charges to selling, general and administrative expenses, principally transaction and integration-related costs related to acquisitions and a divestiture. In addition, the company recorded $33 million of cash restructuring charges, net, primarily for employee severance and abandoned facilities costs associated with the closure and consolidation of facilities in the U.S. and Europe.

demand for testing to diagnose COVID-19 with higher sales of genetic sciences products and, to a lesser extent, bioscience products. Sales also grew due to higher demand for bioproduction products.

Operating income margin was 48.6% in the first nine months of 2020 compared to 35.0% in the first nine months of 2019. The increase resulted primarily from profit on higher sales and, to a lesser extent, sales mix, offset in part by strategic growth investments.

Sales in the Analytical Instruments segment decreased $516 million to $3.49 billion in the first nine months of 2020. Sales decreased $511 million (-13%) due to lower revenues at existing businesses. The unfavorable effects of currency translation resulted in a decrease in revenues of $5 million. The decrease in revenues at existing businesses was primarily the result of reduced demand from industrial customers following business slowing and closures due to COVID-19 and lower sales to academic customers due to pandemic-related closures.

Operating income margin was 13.7% in the first nine months of 2020 compared to 22.0% in the first nine months of 2019. The decrease was primarily due to the decrease in sales, a $108 million charge related to a long-term supply contract (discussed in Note 8), sales mix and, to a lesser extent, strategic growth investments, offset in part by productivity improvements.

Sales in the Specialty Diagnostics segment increased $597 million to $3.38 billion in the first nine months of 2020. Sales increased $724 million (26%) due to higher revenues at existing businesses. The unfavorable effects of currency translation resulted in a decrease in revenues of $6 million and the divestiture of the Anatomical Pathology business decreased revenues by $121 million.

Sales in the Laboratory Products and Services segment increased $864 million to $8.63 billion in 2020. Sales increased $699 million (9%) due to higher revenues at existing businesses and $179 million due to acquisitions. The unfavorable effects of currency translation resulted in a decrease in revenues of $14 million. The increase in revenues at existing businesses was primarily due to increased demand for products sold through its research and safety market channel business and, to a lesser extent, service offerings of the segment's pharma services business.

Operating income margin was 10.8% in the first nine months of 2020 compared to 12.0% in the first nine months of 2019. The decrease was primarily due to sales mix and strategic growth investments, offset in part by profit on higher sales and, to a lesser extent, productivity improvements.

Other Income/Expense, Net

The company reported other (expense) income, net of $(36) million and $25 million in the first nine months of 2020 and 2019, respectively. In 2020, other expense, net includes $81 million of costs for the terminated QIAGEN acquisition, primarily for amortization of loan commitment fees and entering into currency hedging contracts. In 2019, the company recorded $42 million of losses on the early extinguishment of debt.

Provision for Income Taxes

The company recorded a $456 million provision for income taxes in the first nine months of 2020. In the second quarter of 2020, the company implemented foreign tax credit planning in Sweden which resulted in $96 million of foreign tax credits, with no related incremental U.S. income tax expense. The company recorded a $338 million provision for income taxes in the first nine months of 2019 including $191 million related to the gain on the sale of the Anatomical Pathology business. In addition, in 2019, the company recorded a $62 million income tax benefit related to a foreign exchange loss for tax purposes on certain intercompany financing arrangements and implemented foreign tax credit planning in Sweden which resulted in $75 million of foreign tax credits, with no related incremental U.S. income tax expense.

Recent Accounting Pronouncements

A description of recently issued accounting standards is included under the heading “Recent Accounting Pronouncements” in Note 1.

Contingent Liabilities

The company is contingently liable with respect to certain legal proceedings and related matters. An unfavorable outcome that differs materially from current accrual estimates, if any, for one or more of the matters described under the heading “Product Liability, Workers Compensation and Other Personal Injury Matters” in Note 8 could have a material adverse effect on the company’s financial position as well as its results of operations and cash flows.

Liquidity and Capital Resources

Consolidated working capital (current assets less current liabilities) was $12.01 billion at September 26, 2020, compared with $5.70 billion at December 31, 2019. Included in working capital were cash and cash equivalents of $7.54 billion at September 26, 2020 and $2.40 billion at December 31, 2019. The increase in cash was due in part to the issuance of long-term senior notes in March and April 2020.

Liquidity and Capital Resources (continued)

First Nine Months of 2020

Cash provided by operating activities was $4.95 billion during the first nine months of 2020. Cash provided by income was offset in part by investments in working capital. Increases in accounts receivable and inventories used cash of $858 million and $427 million, respectively, primarily to support growth in sales. Changes in other assets and other liabilities provided cash of $1.04 billion primarily due to the timing of payments for compensation and income taxes. Cash payments for income taxes increased to $656 million during the first nine months of 2020, compared with $589 million in the first nine months of 2019. The company made cash contributions to its pension and postretirement benefit plans totaling $45 million during the first nine months of 2020. Payments for restructuring actions, principally severance costs and expenses of real estate consolidation, used cash of $46 million during the first nine months of 2020.

During the first nine months of 2020, the company’s investing activities used $884 million of cash, principally for the purchase of property, plant and equipment.

The company’s financing activities provided $1.01 billion of cash during the first nine months of 2020. Issuance of senior notes provided cash of $3.46 billion. Repayment of senior notes used cash of $712 million. The company’s financing activities also included the repurchase of $1.50 billion of the company's common stock and the payment of $250 million in cash dividends, offset in part by $156 million of net proceeds from employee stock option exercises. On November 8, 2019, the Board of Directors authorized the repurchase of up to $2.50 billion of the company’s common stock. At October 30, 2020, authorization remained for $1.00 billion of future repurchases of the company’s common stock.

The company's commitments for purchases of property, plant and equipment, contractual obligations and other commercial commitments did not change materially between December 31, 2019 and September 26, 2020 except for the long-term lease with CSL Limited discussed in Note 8. The company expects that for all of 2020, expenditures for property, plant and equipment, net of disposals, will be approximately $1.5 billion.

As of September 26, 2020, the company’s short-term debt totaled $2 million. The company has a revolving credit facility with a bank group that provides up to $2.5 billion of unsecured multi-currency revolving credit (Note 7). If the company borrows under this facility, it intends to leave undrawn an amount equivalent to outstanding commercial paper to provide a source of funds in the event that commercial paper markets are not available. As of September 26, 2020, no borrowings were outstanding under the company’s revolving credit facility, although available capacity was reduced by approximately $66 million as a result of outstanding letters of credit.

Approximately half of the company’s cash balances and cash flows from operations are from outside the U.S. The company uses its non-U.S. cash for needs outside of the U.S. including acquisitions and repayment of acquisition-related intercompany debt to the U.S. In addition, the company also transfers cash to the U.S. using non-taxable returns of capital as well as dividends where the related U.S. dividend received deduction or foreign tax credit equals any tax cost arising from the dividends. As a result of using such means of transferring cash to the U.S., the company does not expect any material adverse liquidity effects from its significant non-U.S. cash balances for the foreseeable future.

The company believes that its existing cash and cash equivalents of $7.54 billion as of September 26, 2020 and its future cash flow from operations together with available borrowing capacity under its revolving credit agreement will be sufficient to meet the cash requirements of its existing businesses for the foreseeable future, including at least the next 24 months.

First Nine Months of 2019

Cash provided by operating activities was $3.06 billion during the first nine months of 2019. Cash provided by income was offset in part by investments in working capital. Increases in accounts receivable and inventories used cash of $321 million and $449 million, respectively, primarily to support growth in sales. Changes in other assets and other liabilities used cash of $14 million primarily due to the timing of customer billings. Cash payments for income taxes totaled $589 million. The company made cash contributions to its pension and postretirement benefit plans totaling $40 million during the first nine months of 2019. Payments for restructuring actions, principally severance costs and expenses of real estate consolidation, used cash of $45 million during the first nine months of 2019.

During the first nine months of 2019, the company’s investing activities used $1.15 billion of cash. Acquisitions used cash of $1.69 billion. Proceeds from the sale of the Anatomical Pathology business provided $1.13 billion. The company's investing activities also included the purchase of $637 million of property, plant and equipment.

The company’s financing activities used $2.60 billion of cash during the first nine months of 2019. Repayment of senior notes used cash of $1.70 billion. A net increase in commercial paper obligations provided cash of $3 million. The company’s

financing activities also included the repurchase of $750 million of the company’s common stock and the payment of $221 million in cash dividends, offset in part by $115 million of net proceeds from employee stock option exercises.

Item 3.    Quantitative and Qualitative Disclosures About Market Risk

The company's exposure to market risk from changes in interest rates and currency exchange rates has not changed materially from its exposure discussed in the company’s Annual Report on Form 10-K for the year ended December 31, 2019.

Item 4.    Controls and Procedures

Management’s Evaluation of Disclosure Controls and Procedures

The company’s management, with the participation of the company’s chief executive officer and chief financial officer, has evaluated the effectiveness of the company’s disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this report. Based on such evaluation, the company’s chief executive officer and chief financial officer concluded that, as of the end of such period, the company’s disclosure controls and procedures were effective at the reasonable assurance level.

PART II    OTHER INFORMATION

Item 1.    Legal Proceedings

There are various lawsuits and claims against the company involving product liability, intellectual property, employment and commercial issues. See “Note 8 to our Consolidated Financial Statements – Commitments and Contingencies.”

On June 3, 2013, Unisone Strategic IP filed a complaint against Life Technologies, a subsidiary of the company, in the United States District Court for the Southern District of California alleging patent infringement by Life Technologies’ supply chain management system software, which operates with product “supply centers” installed at customer sites. Plaintiff sought damages for alleged willful infringement, attorneys’ fees, costs, and injunctive relief. On September 30, 2020, this matter was settled by payment of a nominal amount by the company.

Item 1A.    Risk Factors

The risks that we believe are material to our investors are discussed in the company’s Annual Report on Form 10-K for the year ended December 31, 2019, as updated by our Quarterly Report on Form 10-Q for the quarter ended June 27, 2020, under the caption “Risk Factors,” which are on file with the SEC. Except as set forth herein, there have been no material changes during the three months ended September 26, 2020 to our previously reported Risk Factors. As discussed in Note 2, the company has terminated its agreement to acquire QIAGEN, therefore the risks associated with the then pending acquisition of QIAGEN included in the company’s Quarterly Report on Form 10-Q for the quarter ended June 27, 2020 are no longer material risks to the company’s operations.

Item 2.    Unregistered Sales of Equity Securities and Use of Proceeds

Issuer Purchases of Equity Securities

There was no share repurchase activity for the company's third quarter of 2020. On November 8, 2019, the Board of Directors authorized the repurchase of up to $2.50 billion of the company’s common stock. At September 26, 2020, $1.00 billion was available for future repurchases of the company’s common stock under this authorization.

Nature of Operations and Summary of Significant Accounting Policies [Text Block]

Note 1.    Nature of Operations and Summary of Significant Accounting Policies

Nature of Operations

Thermo Fisher Scientific Inc. (the company or Thermo Fisher) enables customers to make the world healthier, cleaner and safer by helping them accelerate life sciences research, solve complex analytical challenges, improve patient diagnostics, deliver medicines to market and increase laboratory productivity. Markets served include pharmaceutical and biotech, academic and government, industrial and applied, as well as healthcare and diagnostics.

Interim Financial Statements

The interim consolidated financial statements presented herein have been prepared by the company, are unaudited and, in the opinion of management, reflect all adjustments of a normal recurring nature necessary for a fair statement of the financial position at September 26, 2020, the results of operations for the three- and nine-month periods ended September 26, 2020 and September 28, 2019, and the cash flows for the nine-month periods ended September 26, 2020 and September 28, 2019. Interim results are not necessarily indicative of results for a full year.

The consolidated balance sheet presented as of December 31, 2019, has been derived from the audited consolidated financial statements as of that date. The consolidated financial statements and notes are presented as permitted by Form 10-Q and do not contain all information that is included in the annual financial statements and notes thereto of the company. The consolidated financial statements and notes included in this report should be read in conjunction with the 2019 financial statements and notes included in the company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission (SEC).

Note 1 to the consolidated financial statements for 2019 describes the significant accounting estimates and policies used in preparation of the consolidated financial statements. There have been no material changes in the company’s significant accounting policies during the nine months ended September 26, 2020.

Contract-related Balances

Accounts receivable include amounts that have been billed and are currently due from customers. They are recorded at the invoiced amount and do not bear interest. The company maintains allowances for doubtful accounts for estimates of expected losses resulting from the inability of its customers to pay amounts due. The allowance for doubtful accounts is the company’s best estimate of the amount of probable credit losses in existing accounts receivable. The company determines the allowance based on history of similarly aged receivables, the creditworthiness of the customer, reasons for delinquency, current economic conditions, expectations associated with future events and circumstances where reasonable and supportable forecasts are available and any other information that is relevant to the judgment. Receivables from academic and government customers as well as large, well-capitalized commercial customers have historically experienced less collectability risk. Account balances are charged off against the allowance when the company believes it is probable the receivable will not be recovered. The company does not have any off-balance-sheet credit exposure related to customers.

The changes in the allowance for doubtful accounts are as follows:

	Nine Months Ended
	September 26,		September 28,
(In millions)	2020		2019
Balance at Beginning of Year	$	102	$	117
Cumulative effect of accounting change	1		—
Provision charged to expense	39		19
Accounts written off	(25)		(26)
Acquisitions, currency translation and other	—		(4)
Balance at End of Period	$	117	$	106

Contract assets include revenues recognized in advance of billings and are recorded net of estimated losses resulting from the inability to invoice customers, which is primarily due to risk associated with the company’s performance. Contract assets are classified as current or noncurrent based on the amount of time expected to lapse until the company's right to consideration

becomes unconditional. Noncurrent contract assets are included within other assets in the accompanying balance sheet. Noncurrent contract liabilities are included within other long-term liabilities in the accompanying balance sheet. Contract assets and liabilities are presented on a net basis in the consolidated balance sheet if they arise from different performance obligations in the same contract. Contract asset and liability balances are as follows:

	September 26,		December 31,
(In millions)	2020		2019
Current Contract Assets, Net	$	697	$	603
Noncurrent Contract Assets, Net	11		17
Current Contract Liabilities	1,047		916
Noncurrent Contract Liabilities	674		594

In the three and nine months ended September 26, 2020, the company recognized revenues of $142 million and $773 million, respectively, that were included in the contract liabilities balance at December 31, 2019.

Warranty Obligations

The liability for warranties is included in other accrued expenses in the accompanying balance sheet. The changes in the carrying amount of standard product warranty obligations are as follows:

Finished Goods	2,024		1,882

Use of Estimates

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period.

The company’s estimates include, among others, asset reserve requirements as well as the amounts of future cash flows associated with certain assets and businesses that are used in assessing the risk of impairment. Risks and uncertainties associated with the ongoing COVID-19 global pandemic have and will continue to materially adversely affect certain of the company’s businesses, particularly in the Analytical Instruments segment and, to a lesser extent, in some businesses within the other three segments, through at least the fourth quarter of 2020. The extent and duration of such impacts are uncertain and may require changes to estimates. Actual results could differ from those estimates.

Recent Accounting Pronouncements

In January 2020, the FASB issued new guidance to clarify the interaction of the accounting for certain equity securities, equity method investments, and certain forward contracts and purchased options. Among other things, the new guidance clarifies that an entity should consider observable transactions that require it to either apply or discontinue the equity method of accounting for the purposes of applying measurement principles for certain equity securities immediately before applying or discontinuing the equity method. The company adopted this guidance in 2020 using a prospective method. The adoption of this guidance did not have a material impact on the company’s consolidated financial statements.

In December 2019, the FASB issued new guidance to simplify the accounting for income taxes. Among other things, the new guidance requires the effects of enacted changes in tax laws or rates to be reflected in the annual effective tax rate computation in the interim period that includes the enactment date. The company expects to adopt this guidance when it is effective in 2021 using a prospective method. The adoption of this guidance is not expected to have a material impact on the company’s consolidated financial statements; however, the impact in future periods will be dependent on the extent of future events or conditions that would be affected such as enacted changes in tax laws or rates.

In August 2018, the FASB issued new guidance to modify the disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. The company adopted the guidance in 2020 using a retrospective method. The adoption of this guidance did not have a material impact on the company’s disclosures.

In August 2018, the FASB issued new guidance to modify the disclosure requirements on fair value measurements. The company adopted the guidance in 2020 with some items requiring a prospective method and others requiring a retrospective method. The adoption of this guidance did not have a material impact on the company’s disclosures.

In June 2016, the FASB issued new guidance to require a financial asset measured at amortized cost basis, such as accounts receivable, to be presented at the net amount expected to be collected based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. During 2018 and 2019, the FASB issued additional guidance and clarification. The company adopted the guidance in 2020 using a modified retrospective method. The adoption of this guidance reduced accounts receivable and retained earnings by $1 million on January 1, 2020.

Business Combinations [Abstract]

Acquisitions and Dispositions [Text Block]

Note 2.    Acquisitions and Dispositions

The company’s acquisitions have historically been made at prices above the determined fair value of the acquired identifiable net assets, resulting in goodwill, primarily due to expectations of the synergies that will be realized by combining the businesses. These synergies include the elimination of redundant facilities, functions and staffing; use of the company’s existing commercial infrastructure to expand sales of the acquired businesses’ products; and use of the commercial infrastructure of the acquired businesses to cost-effectively expand sales of company products.

Acquisitions have been accounted for using the acquisition method of accounting, and the acquired companies’ results have been included in the accompanying financial statements from their respective dates of acquisition. Acquisition transaction costs are recorded in selling, general and administrative expenses as incurred.

Terminated Acquisition

As previously announced, on March 3, 2020, the company entered into a purchase agreement to acquire all of the issued and outstanding shares of QIAGEN N.V. (“QIAGEN”). Following a determination that the number of shares tendered by QIAGEN shareholders did not meet the minimum amount required for the transaction to proceed, on August 13, 2020, the company delivered to QIAGEN a written notice terminating the purchase agreement in accordance with the terms of the agreement. In connection with the termination, QIAGEN paid to the company an expense reimbursement payment of $95 million in cash which has been recorded as a reduction of selling, general and administrative expenses.

Disposition

On June 28, 2019, the company sold its Anatomical Pathology business to PHC Holdings Corporation for $1.13 billion, net of cash divested. The business was part of the Specialty Diagnostics segment. The sale of this business resulted in a pre-tax gain of approximately $482 million in 2019, included in restructuring and other costs (income), net. Revenues in 2019, through the date of sale, of the business sold were approximately $115 million, net of retained sales through the company's healthcare market channel business.

Note 5.    Income Taxes

The provision for income taxes in the accompanying statement of income differs from the provision calculated by applying the statutory federal income tax rate to income before provision for income taxes due to the following:

Provision for Income Taxes	$	456		$	338

The company has operations and a taxable presence in approximately 50 countries outside the U.S. The company's effective income tax rate differs from the U.S. federal statutory rate each year due to certain operations that are subject to tax incentives, state and local taxes, and foreign taxes that are different than the U.S. federal statutory rate.

In the second quarter of 2020, the company implemented foreign tax credit planning in Sweden which resulted in $96 million of foreign tax credits, with no related incremental U.S. income tax expense.

Unrecognized Tax Benefits

As of September 26, 2020, the company had $1.51 billion of unrecognized tax benefits substantially all of which, if recognized, would reduce the effective tax rate.

A reconciliation of the beginning and ending amounts of unrecognized tax benefits is as follows:

See Note 10 for fair value information pertaining to the company’s long-term obligations.

In connection with the termination of the agreement to acquire QIAGEN (Note 2), the company terminated the bridge and term loan commitments which had been available to fund the acquisition. The company had a cash outlay of $51 million in 2020 associated with obtaining the bridge and term loan commitments included in other financing activities, net, in the accompanying statement of cash flows. In 2020, other expense, net includes $81 million of costs for the terminated QIAGEN acquisition, primarily for loan commitment fees and entering into hedging contracts.

Credit Facilities

The company has a revolving credit facility, as amended, (the Facility) with a bank group that provides for up to $2.5 billion of unsecured multi-currency revolving credit. The Facility expires in July 2022. The revolving credit agreement calls for interest at either a LIBOR-based rate, a EURIBOR-based rate (for funds drawn in euro) or a rate based on the prime lending rate of the agent bank, at the company’s option. The agreement contains affirmative, negative and financial covenants, and events of default customary for facilities of this type. The covenants in the Facility include a Consolidated Leverage Ratio (net debt-to-Consolidated EBITDA) and a Consolidated Interest Coverage Ratio (Consolidated EBITDA to Consolidated Interest Expense), as such terms are defined in the Facility. Specifically, the company has agreed that, so long as any lender has any commitment under the Facility, any letter of credit is outstanding under the Facility, or any loan or other obligation is outstanding under the Facility, it will maintain a maximum Consolidated Leverage Ratio of 5.0:1.0, with such ratio stepping down to 4.0 to 1.0 for the two consecutive fiscal quarters starting on the last day of the first fiscal quarter of 2022 and then stepping down to 3.5 to 1.0 for each fiscal quarter ending thereafter. The company has also agreed that so long as any lender has any commitment under the Facility or any letter of credit is outstanding under the Facility, or any loan or other obligation is outstanding under the Facility, it will maintain a minimum Consolidated Interest Coverage Ratio of 3.0:1.0 as of the last day of any fiscal quarter. As of September 26, 2020, no borrowings were outstanding under the Facility, although available capacity was reduced by approximately $66 million as a result of outstanding letters of credit.

Commercial Paper Programs

The company has commercial paper programs pursuant to which it may issue and sell unsecured, short-term promissory notes (CP Notes). Under the U.S. program, a) maturities may not exceed 397 days from the date of issue and b) the CP Notes are issued on a private placement basis under customary terms in the commercial paper market and are not redeemable prior to maturity nor subject to voluntary prepayment. Under the euro program, maturities may not exceed 183 days and may be denominated in euro, U.S. dollars, Japanese yen, British pounds sterling, Swiss franc, Canadian dollars or other currencies. Under both programs, the CP Notes are issued at a discount from par (or premium to par, in the case of negative interest rates), or, alternatively, are sold at par and bear varying interest rates on a fixed or floating basis. As of September 26, 2020, there were no outstanding borrowings under these programs.

Senior Notes

Interest is payable annually on the euro-denominated senior notes and semi-annually on all other senior notes. Each of the notes may be redeemed at a redemption price of 100% of the principal amount plus a specified make-whole premium and accrued interest. The company is subject to certain affirmative and negative covenants under the indentures governing the senior notes, the most restrictive of which limits the ability of the company to pledge principal properties as security under borrowing arrangements.

Interest Rate Swap Arrangements and related Cross-currency Interest Rate Swap Arrangements

The company has entered into LIBOR-based interest rate swap arrangements with various banks. The aggregate amounts of the swaps are equal to the principal amount of the notes and the payment dates of the swaps coincide with the interest payment dates of the note. The swap contracts provide for the company to pay a variable interest rate and receive a fixed rate. The variable interest rates reset monthly. The swaps have been accounted for as fair value hedges of the notes. See Note 10 for additional information on the interest rate swap arrangements and related cross-currency interest rate swap arrangements. The following table summarizes the outstanding interest rate swap arrangements on the company's senior notes at September 26, 2020:

	Aggregate Notional Amount		Pay Rate as of
(Dollars in millions)		Pay Rate	September 26, 2020		Receive Rate
3.00% Senior Notes due 2023 (a)	1,000	1-month LIBOR + 1.7640%	1.9164	%	3.00	%

(a) The payments on $900 million notional value of these interest rate swaps are offset in part by cross-currency interest rate swaps which effectively reduced the pay rate as of September 26, 2020 from 1.92% to a weighted average of 1.13%.

The company has entered into $900 million notional value of cross-currency interest rate swaps, which effectively convert a portion of the semi-annual payments related to the variable rate, U.S. dollar denominated, LIBOR-based interest rate swaps to payments on variable rate, euro denominated, EURIBOR-based cross-currency interest rate swaps.

Note 8.    Commitments and Contingencies

Environmental Matters

The company is currently involved in various stages of investigation and remediation related to environmental matters. The company cannot predict all potential costs related to environmental remediation matters and the possible impact on future operations given the uncertainties regarding the extent of the required cleanup, the complexity and interpretation of applicable laws and regulations, the varying costs of alternative cleanup methods and the extent of the company’s responsibility. Expenses for environmental remediation matters related to the costs of installing, operating and maintaining groundwater-treatment systems and other remedial activities related to historical environmental contamination at the company’s domestic and international facilities were not material in any period presented. The company records accruals for environmental remediation liabilities, based on current interpretations of environmental laws and regulations, when it is probable that a liability has been incurred and the amount of such liability can be reasonably estimated. The company calculates estimates based upon several factors, including input from environmental specialists and management’s knowledge of and experience with these environmental matters. The company includes in these estimates potential costs for investigation, remediation and operation and maintenance of cleanup sites. At September 26, 2020, the company’s total environmental liability was approximately $70 million. While management believes the accruals for environmental remediation are adequate based on current estimates of remediation costs, the company may be subject to additional remedial or compliance costs due to future events such as changes in existing laws and regulations, changes in agency direction or enforcement policies, developments in remediation technologies or changes in the conduct of the company’s operations, which could have a material adverse effect on the company’s financial position, results of operations or cash flows.

Litigation and Related Contingencies

There are various lawsuits and claims pending against the company including matters involving product liability, intellectual property, employment and commercial issues. The company determines the probability and range of possible loss based on the current status of each of these matters. A liability is recorded in the financial statements if it is believed to be probable that a loss has been incurred and the amount of the loss can be reasonably estimated. The company establishes a liability that is an estimate of amounts expected to be paid in the future for events that have already occurred. The company accrues the most likely amount or at least the minimum of the range of probable loss when a range of probable loss can be estimated. The accrued liabilities are based on management’s judgment as to the probability of losses for asserted and unasserted claims and, where applicable, actuarially determined estimates. Accrual estimates are adjusted as additional information becomes known or payments are made. The amount of ultimate loss may differ from these estimates. Due to the inherent uncertainties associated with pending litigation or claims, the company cannot predict the outcome, nor, with respect to certain pending litigation or claims where no liability has been accrued, make a meaningful estimate of the reasonably possible loss or range of loss that could result from an unfavorable outcome. The company has no material accruals for pending litigation or claims for which accrual amounts are not disclosed below or in the company's 2019 financial statements and notes included in the company's Annual Report on Form 10-K filed with the SEC, nor are material losses deemed probable for such matters. It is reasonably possible, however, that an unfavorable outcome that exceeds the company’s current accrual estimate, if any, for one or more of the matters described below could have a material adverse effect on the company’s results of operations, financial position and cash flows.

Product Liability, Workers Compensation and Other Personal Injury Matters

For product liability, workers compensation and other personal injury matters, the company accrues the most likely amount or at least the minimum of the range of possible loss when a range of possible loss can be estimated. The company records estimated amounts due from insurers related to certain product liabilities as an asset. Although the company believes that the amounts accrued and estimated recoveries are probable and appropriate based on available information, including actuarial studies of loss estimates, the process of estimating losses and insurance recoveries involves a considerable degree of judgment by management and the ultimate amounts could vary materially. Insurance contracts do not relieve the company of its primary obligation with respect to any losses incurred. The collectability of amounts due from its insurers is subject to the solvency and willingness of the insurer to pay, as well as the legal sufficiency of the insurance claims. Management monitors the payment history as well as the financial condition and ratings of its insurers on an ongoing basis.

Intellectual Property Matters

On June 3, 2013, Unisone Strategic IP filed a complaint against Life Technologies, a subsidiary of the company, in the United States District Court for the Southern District of California alleging patent infringement by Life Technologies’ supply chain management system software, which operates with product “supply centers” installed at customer sites. Plaintiff sought damages for alleged willful infringement, attorneys’ fees, costs, and injunctive relief. On September 30, 2020, this matter was settled by payment of a nominal amount by the company.

Strategic Partnership and Long-term Lease

In May 2020, the company entered a strategic partnership with CSL Limited (CSL). Through a long-term lease agreement with CSL, the company will operate a new state-of-the-art biologics manufacturing facility in Lengnau, Switzerland, when construction is completed in mid-2021, to perform pharma services for CSL with capacity to serve other customers as well. The company made an initial lease payment of $50 million in the second quarter of 2020 (included within other assets in the accompanying balance sheet) and expects to make additional fixed lease payments aggregating to $555 million (excluding renewals) from 2021 to 2041, with additional amounts dependent on the extent of revenues from customers of the facility other than CSL.

Loss on Supply Agreement

The Analytical Instruments segment recorded a charge to cost of product revenues for $108 million in the third quarter of 2020 related to an existing supply contract for components of electron microscopy instruments. The agreement requires the company to make future minimum purchases through 2025. The company has developed and launched an alternative product beginning in 2020 and based on the expected demand for the internally developed product vs. the third-party product, the company does not expect to use all of the product it will be required to buy, resulting in a loss on the purchase commitment.

The company uses the Black-Scholes model to value its warrants. The company determines the fair value of its insurance contracts by obtaining the cash surrender value of the contracts from the issuer. The fair value of derivative contracts is the estimated amount that the company would receive/pay upon liquidation of the contracts, taking into account the change in interest rates and currency exchange rates. The company determines the fair value of acquisition-related contingent consideration based on the probability-weighted discounted cash flows associated with such future payments. Changes to the

fair value of contingent consideration are recorded in selling, general and administrative expense. The following table provides a rollforward of the fair value, as determined by level 3 inputs, of the contingent consideration.

Gains and losses recognized on currency exchange contracts and the interest rate swaps designated as fair value hedges are included in the consolidated statement of income together with the corresponding, offsetting losses and gains on the underlying hedged transactions.

The company also uses foreign currency-denominated debt and cross-currency interest rate swaps to partially hedge its net investments in foreign operations against adverse movements in exchange rates. The majority of the company’s euro-denominated senior notes and certain of its cross-currency interest rate swaps have been designated as, and are effective as, economic hedges of part of the net investment in a foreign operation. Accordingly, foreign currency transaction gains or losses due to spot rate fluctuations on the euro-denominated debt instruments and contract fair value changes on the cross-currency

interest rate swaps, excluding interest accruals, are included in currency translation adjustment within other comprehensive items and shareholders’ equity.

The company also had $1 billion notional value of cross currency swaps which the company terminated in October 2020. These swaps were entered into in anticipation of using U.S. dollars to partially finance the euro purchase price of the terminated QIAGEN acquisition (Note 2). Gains and losses associated with these swaps were recorded in other expense, net.

See Note 1 to the consolidated financial statements for 2019 included in the company's Annual Report on Form 10-K and Note 7 herein for additional information on the company's risk management objectives and strategies.

Cash Flow Hedge Arrangements

In March 2020, the company entered into interest rate swap arrangements to mitigate the risk of interest rates rising prior to completion of future debt offerings. Based on the company's conclusion that the debt offerings are probable, the swaps hedge the cash flow risk for each of the interest payments on the planned fixed-rate debt issues. One of these hedges was terminated in March 2020, in connection with the debt offering completed in that month. The remaining hedges were terminated in July 2020. The aggregate fair value of the terminated hedges, net of tax, has been classified as a reduction to accumulated other comprehensive items and will be amortized to interest expense over the term of the related debt issuances. The company had cash outlays aggregating $85 million in 2020 associated with termination of the arrangements, included in other financing activities, net, in the accompanying statement of cash flows.

Fair Value of Other Financial Instruments

The carrying value and fair value of the company’s debt obligations are as follows:

Restructuring and Other Costs, Net [Text Block]

Note 12.    Restructuring and Other Costs (Income), Net

In the first nine months of 2020 the company recorded transaction/integration costs (including reimbursement thereof) related to recent/terminated acquisitions, continuing charges for headcount reductions and facility consolidations in an effort to streamline operations, and, to a lesser extent, impairment of acquired technology in development and non-cash charges for writedowns of fixed assets to estimated disposal value in connection with the consolidation of commercial production operations in the U.S. In the first nine months of 2020, severance actions associated with facility consolidations and cost reduction measures affected less than 1% of the company’s workforce.

As of October 30, 2020, the company has identified restructuring actions that will result in additional charges of approximately $45 million, primarily in 2020 and 2021, and expects to identify additional actions during 2020 which will be recorded when specified criteria are met, such as communication of benefit arrangements or when the costs have been incurred.

During the third quarter of 2020, the company recorded net restructuring and other costs (income) by segment as follows:

(In millions)	Cost of Revenues		Selling, General and Administrative Expenses		Restructuring and Other Costs, Net		Total

The principal components of net restructuring and other costs (income) by segment are as follows:

Life Sciences Solutions

In the first nine months of 2020, the Life Sciences Solutions segment recorded $3 million of net restructuring and other charges. The segment recorded $11 million of restructuring and other costs, net, primarily charges for impairment of acquired technology in development. The segment also recorded $8 million of credits to selling, general, and administrative expense for changes in estimates of contingent acquisition consideration.

Analytical Instruments

In the first nine months of 2020, the Analytical Instruments segment recorded $22 million of net restructuring and other charges, primarily for employee severance associated with headcount reductions in Europe, China, and the U.S., and, to a lesser extent, abandoned facility costs.

Specialty Diagnostics

In the first nine months of 2020, the Specialty Diagnostics segment recorded $4 million of net restructuring and other charges, principally charges for third-party transaction costs (including reimbursement thereof) for a terminated acquisition.

Laboratory Products and Services

In the first nine months of 2020, the Laboratory Products and Services segment recorded $27 million of net restructuring and other charges, primarily for employee severance at businesses streamlining operations and for writedowns of fixed assets to estimated disposal value in connection with the consolidation of commercial production operations in the U.S.

Corporate

In the first nine months of 2020, the company recorded $9 million of net restructuring and other costs for severance at its corporate operations and, to a lesser extent, charges to selling, general, and administrative expense for product liability litigation.

The following table summarizes the changes in the company’s accrued restructuring balance. Other amounts reported as restructuring and other costs, net, in the accompanying statement of income have been summarized in the notes to the table. Accrued restructuring costs are included in other accrued expenses in the accompanying balance sheet.

Balance at September 26, 2020	$	32

(a)The movements in the restructuring liability principally consist of severance and other costs such as relocation and moving expenses associated with facility consolidations, as well as employee retention costs which are accrued ratably over the period through which employees must work to qualify for a payment.

(b)Excludes $24 million of charges for impairment of acquired technology in development, fixed asset writedowns and costs associated with environmental remediation at abandoned / previously owned facilities.

The company expects to pay accrued restructuring costs primarily through 2021.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Receivables, Trade and Other Accounts Receivable, Allowance for Doubtful Accounts, Policy [Policy Text Block]

Accounts receivable include amounts that have been billed and are currently due from customers. They are recorded at the invoiced amount and do not bear interest. The company maintains allowances for doubtful accounts for estimates of expected losses resulting from the inability of its customers to pay amounts due. The allowance for doubtful accounts is the company’s best estimate of the amount of probable credit losses in existing accounts receivable. The company determines the allowance based on history of similarly aged receivables, the creditworthiness of the customer, reasons for delinquency, current economic conditions, expectations associated with future events and circumstances where reasonable and supportable forecasts are available and any other information that is relevant to the judgment. Receivables from academic and government customers as well as large, well-capitalized commercial customers have historically experienced less collectability risk. Account balances are charged off against the allowance when the company believes it is probable the receivable will not be recovered. The company does not have any off-balance-sheet credit exposure related to customers.

Use of Estimates [Policy Text Block]

Use of Estimates

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period.

The company’s estimates include, among others, asset reserve requirements as well as the amounts of future cash flows associated with certain assets and businesses that are used in assessing the risk of impairment. Risks and uncertainties associated with the ongoing COVID-19 global pandemic have and will continue to materially adversely affect certain of the company’s businesses, particularly in the Analytical Instruments segment and, to a lesser extent, in some businesses within the other three segments, through at least the fourth quarter of 2020. The extent and duration of such impacts are uncertain and may require changes to estimates. Actual results could differ from those estimates.

New Accounting Pronouncements, Policy [Policy Text Block]

Recent Accounting Pronouncements

In January 2020, the FASB issued new guidance to clarify the interaction of the accounting for certain equity securities, equity method investments, and certain forward contracts and purchased options. Among other things, the new guidance clarifies that an entity should consider observable transactions that require it to either apply or discontinue the equity method of accounting for the purposes of applying measurement principles for certain equity securities immediately before applying or discontinuing the equity method. The company adopted this guidance in 2020 using a prospective method. The adoption of this guidance did not have a material impact on the company’s consolidated financial statements.

In December 2019, the FASB issued new guidance to simplify the accounting for income taxes. Among other things, the new guidance requires the effects of enacted changes in tax laws or rates to be reflected in the annual effective tax rate computation in the interim period that includes the enactment date. The company expects to adopt this guidance when it is effective in 2021 using a prospective method. The adoption of this guidance is not expected to have a material impact on the company’s consolidated financial statements; however, the impact in future periods will be dependent on the extent of future events or conditions that would be affected such as enacted changes in tax laws or rates.

In August 2018, the FASB issued new guidance to modify the disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. The company adopted the guidance in 2020 using a retrospective method. The adoption of this guidance did not have a material impact on the company’s disclosures.

In August 2018, the FASB issued new guidance to modify the disclosure requirements on fair value measurements. The company adopted the guidance in 2020 with some items requiring a prospective method and others requiring a retrospective method. The adoption of this guidance did not have a material impact on the company’s disclosures.

In June 2016, the FASB issued new guidance to require a financial asset measured at amortized cost basis, such as accounts receivable, to be presented at the net amount expected to be collected based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. During 2018 and 2019, the FASB issued additional guidance and clarification. The company adopted the guidance in 2020 using a modified retrospective method. The adoption of this guidance reduced accounts receivable and retained earnings by $1 million on January 1, 2020.

Business Combinations Policy [Policy Text Block]

The company’s acquisitions have historically been made at prices above the determined fair value of the acquired identifiable net assets, resulting in goodwill, primarily due to expectations of the synergies that will be realized by combining the businesses. These synergies include the elimination of redundant facilities, functions and staffing; use of the company’s existing commercial infrastructure to expand sales of the acquired businesses’ products; and use of the commercial infrastructure of the acquired businesses to cost-effectively expand sales of company products. Acquisitions have been accounted for using the acquisition method of accounting, and the acquired companies’ results have been included in the accompanying financial statements from their respective dates of acquisition. Acquisition transaction costs are recorded in selling, general and administrative expenses as incurred.
