Organization, Consolidation and Presentation of Financial Statements [Abstract]  
Nature of Operations and Summary of Significant Accounting Policies 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, increase laboratory productivity, and improve patient health through diagnostics and the development and manufacture of life-changing therapies. Markets served include pharmaceutical and biotech, academic and government, industrial and applied, as well as healthcare and diagnostics.
Principles of Consolidation
The accompanying financial statements include the accounts of the company and its wholly and majority-owned subsidiaries. All material intercompany accounts and transactions have been eliminated.
Redeemable Noncontrolling Interest
The company owns 60% of its consolidated subsidiary PPD-SNBL K.K. The 40% ownership interest held by a third party is classified as a redeemable noncontrolling interest on the consolidated balance sheet due to certain put options under which the third party may require the company to purchase the remaining ownership interest at a premium upon the occurrence of certain events.
Presentation
Certain reclassifications of prior year amounts have been made to conform to the current year presentation.
Amounts and percentages reported within these consolidated financial statements are presented and calculated based on underlying unrounded amounts. As a result, the sum of components may not equal corresponding totals due to rounding.
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. Actual results could differ from those estimates.
Cash and Cash Equivalents
Cash equivalents consists principally of money market funds and other marketable securities purchased with a remaining maturity of three months or less. These investments are carried at cost, which approximates market value (see Note 4).
Inventories
Inventories are valued at the lower of cost or net realizable value, cost being determined by the first-in, first-out (FIFO) method. The company periodically reviews quantities of inventories on hand and compares these amounts to the expected use of each product or product line. In addition, the company has certain inventory that is subject to fluctuating market pricing. The company records a charge to cost of sales for the amount required to reduce the carrying value of inventory to net realizable value. Costs associated with the procurement of inventories, such as inbound freight charges, purchasing and receiving costs, and internal transfer costs, are included in cost of revenues in the accompanying statement of income.
Contract-related Balances
Accounts receivable include unconditional rights to consideration from customers, which generally represent billings that 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.
Contract assets include revenues recognized in advance of billings where the company’s right to bill includes something other than the passage of time. Such amounts 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.
Contract liabilities include billings in excess of revenues recognized, such as those resulting from customer advances and deposits and unearned revenues on service contracts. Contract liabilities are classified as current or noncurrent based on the periods over which remaining performance obligations are expected to be transferred to customers. 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.
Noncurrent contract assets and noncurrent contract liabilities are included within other assets and other long-term liabilities in the accompanying balance sheet, respectively (see Note 2).
Property, Plant and Equipment
Property, plant and equipment are recorded at cost. The costs of additions and improvements are capitalized, while maintenance and repairs are charged to expense as incurred. The company generally provides for depreciation and amortization using the straight-line method over the estimated useful lives of the property as follows: buildings and improvements, 25 to 40 years; machinery and equipment (including software), 3 to 10 years; and leasehold improvements, the shorter of the term of the lease or the life of the asset. When assets are retired or otherwise disposed of, the assets and related accumulated depreciation are eliminated from the accounts and the resulting gain or loss is reflected in the accompanying statement of income.
Acquisition-related Intangible Assets
Acquisition-related intangible assets include the costs of acquired customer relationships, product technology, tradenames, backlog and other specifically identifiable intangible assets, and are being amortized using the straight-line method over their estimated useful lives, which range up to 20 years. The company reviews these intangible assets for impairment when indication of potential impairment exists, such as a significant reduction in cash flows associated with the assets. When impairment indicators exist, the company determines whether the carrying value of its intangible assets exceeds the related undiscounted cash flows. In these situations, the carrying value is written down to fair value.
In addition, the company has tradenames that have indefinite lives and which are not amortized. Intangible assets with indefinite lives are reviewed for impairment annually or whenever events or changes in circumstances indicate they may be impaired. The company may perform an optional qualitative assessment. If the company determines that the fair value of the indefinite-lived intangible asset is more likely than not greater than its carrying amount, no additional testing is necessary. If not, or if the company bypasses the optional qualitative assessment, it writes the carrying value down to the fair value, if applicable.
Investments
Investments include marketable securities, such as marketable equity securities, available for sale debt securities, and bank time deposits with maturities greater than three months, equity method investments, and non-marketable equity investments. The company classifies investments as current or noncurrent based on the nature of the securities and their availability for use in current operations. Noncurrent investments are included in other assets.
Marketable securities are stated at fair value with all realized and unrealized gains and losses on investments in marketable equity securities and realized gains and losses on available-for-sale debt securities recognized in other income/(expense).
The company accounts for investments in businesses using the equity method when it has the ability to exercise significant influence but not control (generally between 20% and 50% ownership), is not the primary beneficiary and has not elected the fair value option. The company has elected the fair value option of accounting for certain of its investments with readily determinable fair values that would otherwise be accounted for under the equity method (see Note 2). The company’s share of gains and losses in, and impairments of, equity method investments are recorded in equity in earnings (losses) of unconsolidated entities. Equity investments that do not have readily determinable fair values and are not eligible for the net asset value (NAV) practical expedient are measured at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or similar investments of the same issuer. The company performs qualitative assessments to identify impairments of these investments. All gains and losses on non-equity method investments are recognized in other income/(expense).
Other Assets
Other assets in the accompanying balance sheet include operating lease right-of-use assets, investments, deferred tax assets, pension assets, insurance recovery receivables related to product liability matters, certain intangible assets and other assets.
Goodwill
The company assesses goodwill for impairment at the reporting unit level annually and whenever events occur or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. Such events or circumstances generally include the occurrence of operating losses or a significant decline in earnings associated with one or more of the company’s reporting units. The company is permitted to first assess qualitative factors to determine whether the quantitative goodwill impairment test is necessary. If the qualitative assessment results in a determination that the fair value of a reporting unit is more likely than not less than its carrying amount, the company performs a quantitative goodwill impairment test. The company may bypass the qualitative assessment for the reporting unit in any period and proceed directly to the quantitative goodwill impairment test. The company estimates the fair value of its reporting units by using forecasts of discounted future cash flows and peer market multiples. The company would record an impairment charge based on the excess of a reporting unit’s carrying amount over its fair value (limited to the amount of goodwill). The company determined that no impairments existed in 2024, 2023 or 2022.
Fair Value Measurements
Assets and liabilities carried at fair value are classified and disclosed in one of the following three categories:
Level 1: Quoted market prices in active markets for identical assets or liabilities that the company has the ability to access.
Level 2: Observable market based inputs or unobservable inputs that are corroborated by market data such as quoted prices, interest rates and yield curves.
Level 3: Inputs are unobservable data points that are not corroborated by market data.
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 initially measures the fair value of acquisition-related contingent consideration based on amounts expected to be transferred (probability-weighted) discounted to present value. Changes to the fair values of contingent consideration are recorded in selling, general and administrative expense. The company determines the fair value of its equity method and non-marketable equity investments that are not eligible for the NAV practical expedient by considering factors such as financial position, operating results and cash flows of the investee; recent transactions in the same or similar securities; significant recent events affecting the investee; the price paid by Thermo Fisher; among others.
Loss Contingencies
Accruals are recorded for various contingencies, including legal proceedings, environmental, workers’ compensation, product, general and auto liabilities, self-insurance and other claims that arise in the normal course of business. The accruals are based on management’s judgment, historical claims experience, the probability of losses and, where applicable, the consideration of opinions of internal and/or external legal counsel and actuarial estimates. Additionally, the company records receivables from third-party insurers up to the amount of the loss when recovery has been determined to be probable.
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.
The company determines the probability and range of possible loss for its litigation and other contingencies 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.
Warranty Obligations
The company provides for the estimated cost of standard product warranties, primarily from historical information, in cost of product revenues at the time product revenues are recognized. The liability for warranties is included in other accrued expenses in the accompanying balance sheet. Extended warranty agreements are considered service contracts, which are discussed above. Costs of service contracts are recognized as incurred.
Foreign Currency Translation
All assets and liabilities of the company’s subsidiaries operating in non-U.S. dollar currencies are translated at period-end exchange rates. Resulting translation adjustments are reflected in the “accumulated other comprehensive items” component of shareholders’ equity. Revenues and expenses are translated at average exchange rates for the period.
Revenue Recognition
Consumables revenues consist of single-use products and are recognized at a point in time following the transfer of control of such products to the customer, which generally occurs upon shipment. Instruments revenues typically consist of longer-lived assets that, for the substantial majority of sales, are recognized at a point in time in a manner similar to consumables. Service revenues (primarily clinical research, pharmaceutical, and instrument and enterprise services) are recognized over time as customers receive and consume the benefits of such services. For revenues recognized over time, the company generally uses costs accumulated relative to total estimated costs to measure progress as this method approximates satisfaction of the performance obligation. For contracts that contain multiple performance obligations, the company allocates the consideration to which it expects to be entitled (i.e., the transaction price) to each performance obligation based on relative standalone selling prices and recognizes the related revenues when or as control of each individual performance obligation is transferred to customers. The company exercises judgment in determining the timing of revenue by analyzing the point in time or the period over which the customer has the ability to direct the use of and obtain substantially all of the remaining benefits of the asset. The company immediately expenses contract costs that would otherwise be capitalized and amortized over a period of less than one year.
Changes to the scope of services contracts generally also include changes in the transaction price. Typically, these contract modifications are not distinct from existing services provided under the contract, and result in cumulative adjustments to revenue on the modification date. However, some modifications are distinct from existing services provided under the contract and recognized prospectively.
Payments from customers for most instruments and consumables are typically due in a fixed number of days after shipment or delivery of the product. Service arrangements commonly call for payments in advance of performing the work (e.g., extended service contracts), upon completion of the service (e.g., pharmaceutical services) or a mix of both. Some arrangements include variable amounts of consideration that arise from discounts, rebates, and other programs and practices. In such arrangements, the company estimates the amount by which to reduce the stated contract amount to reflect the transaction price. The company records reimbursement for third-party pass-through and out-of-pocket costs as revenues and the related expenses as costs of revenues.
Research and Development
The company conducts research and development activities to increase its depth of capabilities in technologies, software and services. Research and development costs include employee compensation and benefits, consultants, facilities related costs, material costs, depreciation and travel. Research and development costs are expensed as incurred.
Restructuring Costs
Accounting for the timing and amount of termination benefits provided by the company to employees is determined based on whether: (a) the company has a substantive plan to provide such benefits, (b) the company has a written employment contract with the affected employees that includes a provision for such benefits, (c) the termination benefits are due to the occurrence of an event specified in an existing plan or agreement, or (d) the termination benefits are a one-time benefit. In certain circumstances, employee termination benefits may meet more than one of the characteristics listed above and therefore, may have individual elements that are subject to different accounting models.
From time to time when executing a restructuring or exit plan, the company also incurs costs other than termination benefits, such as lease termination costs, that are not associated with or will not be incurred to provide economic benefits to the company. These include costs that represent amounts under contractual obligations that exist prior to the restructuring plan communication date and will either continue after the restructuring plan is completed with no economic benefit or result in a penalty to cancel a contractual obligation. Such costs are recognized when incurred, which generally occurs at the contract termination or over the period from when a plan to abandon a leased facility is approved through the cease-use date but charges may continue over the remainder of the original contractual period.
Earnings per Share
Basic earnings per share has been computed by dividing net income attributable to Thermo Fisher Scientific Inc. by the weighted average number of shares outstanding during the year. Except where the result would be antidilutive to net income
attributable to Thermo Fisher Scientific Inc., diluted earnings per share has been computed using the treasury stock method for outstanding stock options and restricted units (see Note 6).
Income Taxes
The company recognizes deferred income taxes based on the expected future tax consequences of differences between the financial statement basis and the tax basis of assets and liabilities, calculated using enacted tax rates in effect for the year in which the differences are expected to be reflected in the tax return. A valuation allowance is provided for tax assets that will more likely than not go unused.
The financial statements reflect expected future tax consequences of uncertain tax positions that the company has taken or expects to take on a tax return presuming the taxing authorities’ full knowledge of the positions and all relevant facts, but without discounting for the time value of money (see Note 7).
Derivative Contracts
The company is exposed to certain risks relating to its ongoing business operations including changes to interest rates and currency exchange rates. The company uses derivative instruments primarily to manage currency exchange and interest rate risks. The company recognizes derivative instruments as either assets or liabilities and measures those instruments at fair value. If a derivative is a hedge, depending on the nature of the hedge, changes in the fair value of the derivative are either offset against the change in fair value of the hedged item through earnings or recognized in other comprehensive items until the hedged item is recognized in earnings. Derivatives that are not designated as hedges are recorded at fair value through earnings.
The company uses short-term forward and option currency exchange contracts primarily to hedge certain balance sheet and operational exposures resulting from changes in currency exchange rates, predominantly intercompany loans and cash balances that are denominated in currencies other than the functional currencies of the respective operations. The currency-exchange contracts principally hedge transactions denominated in euro, Canadian dollars, British pounds sterling, Swedish krona, Singapore dollars, Hong Kong dollars and Swiss franc. The company does not hold or engage in transactions involving derivative instruments for purposes other than risk management.
Cash flow hedges. For derivative instruments that are designated and qualify as a cash flow hedge, the gain or loss on the derivative is reported as a component of other comprehensive items and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings and is presented in the same income statement line item as the earnings effect of the hedged item.
Fair value hedges. For derivative instruments that are designated and qualify as a fair value hedge, the gain or loss on the derivative, as well as the offsetting loss or gain on the hedged item attributable to the hedged risk, are recognized in earnings.
Net investment hedges. The company uses foreign currency-denominated debt, certain foreign currency-denominated payables, and cross-currency interest rate swaps to partially hedge its net investments in foreign operations against adverse movements in exchange rates. A portion of the company’s euro-denominated senior notes, certain foreign currency-denominated payables, and 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 certain foreign currency-denominated payables, 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 fair value of the cross-currency interest rate swaps is included in the accompanying balance sheets under the caption other assets or other long-term liabilities. The fair value of the currency exchange contracts is included in the accompanying balance sheets under the captions other current assets or other accrued expenses.
Leases
Operating leases that have commenced are included in other assets, other accrued expenses and other long-term liabilities in the consolidated balance sheet. Finance leases that have commenced are included in property, plant and equipment, net, current maturities of long-term obligations and long-term obligations in the consolidated balance sheet. Classification of lease liabilities as either current or noncurrent is based on the expected timing of payments due under the company’s obligations.
Right-of-use (ROU) assets represent the company’s right to use an underlying asset for the lease term and lease liabilities represent the company’s obligation to make lease payments arising from the lease. Lease ROU assets and liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. Leases with an initial term of 12 months or less are not recorded on the consolidated balance sheet. The company recognizes operating lease
expense on a straight-line basis over the lease term. Finance lease expense includes depreciation, which is recognized on a straight-line basis over the expected life of the leased asset, and an immaterial amount of interest expense.
Because most of the company’s leases do not provide an implicit interest rate, the company estimates incremental borrowing rates based on the information available at the commencement date in determining the present value of lease payments. The company uses the implicit rate when readily determinable. Lease terms include the effect of options to extend or terminate the lease when it is reasonably certain that the company will exercise that option.
As a lessee, the company accounts for the lease and non-lease components as a single lease component (see Note 13).
Pension and Other Postretirement Benefit Plans
The company recognizes the funded status of defined benefit pension and other postretirement benefit plans as an asset or liability. This amount is defined as the difference between the fair value of plan assets and the benefit obligation. The company is required to recognize as a component of other comprehensive items, net of tax, the actuarial gains/losses and prior service costs/credits that arise but were not previously required to be recognized as components of net periodic benefit cost/(income). Other comprehensive items is adjusted as these amounts are later recognized in income as components of net periodic benefit cost/(income).
When a company with a pension plan is acquired, any excess of projected benefit obligation over the plan assets is recognized as a liability and any excess of plan assets over the projected benefit obligation is recognized as an asset. The recognition of a new liability or a new asset results in the elimination of (a) previously existing unrecognized net gain or loss and (b) unrecognized prior service cost or credits.
The company funds annually, at a minimum, the statutorily required minimum amount as actuarially determined.
The discount rate used to determine projected benefit obligations and net periodic pension benefit cost/(income) reflects the rate the company would have to pay to purchase high-quality investments that would provide cash sufficient to settle its current pension obligations. The discount rate is determined based on a range of factors, including the rates of return on high-quality, fixed-income corporate bonds and the related expected duration of the obligations or, in certain instances, the company has used a hypothetical portfolio of high quality instruments with maturities that mirror the benefit obligation in order to accurately estimate the discount rate relevant to a particular plan.
The company utilizes a full yield curve approach in the estimation of these components by applying the specific spot-rates along the yield curve used in the determination of the benefit obligation to the relevant projected cash flows.
The expected long-term rate of return on plan assets used to determine net periodic pension benefit cost/(income) reflects the average rate of earnings expected on the funds invested, or to be invested, to provide for the benefits included in the projected benefit obligations. In determining the expected long-term rate of return on plan assets, the company considers the relative weighting of plan assets, the historical performance of total plan assets and individual asset classes and economic and other indicators of future performance. In addition, the company may consult with and consider the opinions of financial and other professionals in developing appropriate return benchmarks.
Asset management objectives include maintaining an adequate level of diversification to reduce interest rate and market risk and providing adequate liquidity to meet immediate and future benefit payment requirements.
The expected rate of compensation increase used to determine net periodic pension benefit cost/(income) reflects the long-term average rate of salary increases and is based on historic salary increase experience and management’s expectations of future salary increases (see Note 14).
Stock-based Compensation Expense
Compensation cost is based on the grant-date fair value and is recognized ratably over the requisite vesting period or to the date based on qualifying retirement eligibility, if earlier, and is primarily included in selling, general and administrative expenses.
The company’s practice is to grant stock options at fair market value. Options vest over 3-5 years with terms of 7-10 years, assuming continued employment with certain exceptions. Vesting of the option awards is contingent upon meeting certain service conditions. The fair value of most option grants is estimated using the Black-Scholes option pricing model. For option grants that require the achievement of both service and market conditions, a lattice model is used to estimate fair value. The fair value is then amortized on a straight-line basis over the requisite service periods of the awards, which is generally the vesting period. Use of a valuation model requires management to make certain assumptions with respect to selected model inputs. Expected volatility is calculated based on the historical volatility of the company’s stock. Historical data on exercise patterns is the basis for estimating the expected life of an option. The risk-free interest rate is based on U.S. Treasury zero-coupon issues with a remaining term which approximates the expected life assumed at the date of grant. The expected annual dividend rate is
calculated by dividing the company’s annual dividend, based on the most recent quarterly dividend rate, by the closing stock price on the grant date. The compensation expense recognized for all stock-based awards is net of estimated forfeitures. Forfeitures are estimated based on an analysis of actual option forfeitures.
Awards of restricted units convert into an equivalent number of shares of common stock. The awards generally vest over 3-4 years, assuming continued employment, with some exceptions. Vesting of the awards is contingent upon meeting certain service conditions and may also be contingent upon meeting certain performance and/or market conditions. The fair market value of the award at the time of the grant is amortized to expense over the requisite service period of the award, which is generally the vesting period. Recipients of restricted units have no voting rights but are entitled to accrue dividend equivalents. The fair value of service- and performance-based restricted unit awards is determined based on the number of units granted and the market value of the company’s shares on the grant date. For awards with market-based vesting conditions, the company uses a lattice model to estimate the grant-date fair value of the award (see Note 15).
Government Assistance
From time to time, the company receives assistance from various governmental agencies generally in the form of cash or non-income tax credits. These programs help offset the costs of certain research and development activities, facility construction and expansion efforts, or hiring objectives. When the company believes that it is probable that it will meet the conditions tied to the assistance, it offsets the associated expense in the consolidated income statement. Such amounts were not material to the consolidated financial statements as of and for the years ended December 31, 2024, 2023 and 2022.

In addition to available borrowings under the company’s revolving credit agreements, discussed below, the company had unused lines of credit of $65 million as of December 31, 2024. These unused lines of credit generally provide for short-term unsecured borrowings at various interest rates.
Credit Facilities
The company has a revolving credit facility (the Facility) with a bank group that provides for up to $5.00 billion of unsecured multi-currency revolving credit. The Facility expires on January 7, 2027. The revolving credit agreement calls for interest at either a Term Secured Overnight Financing Rate (SOFR), a Euro Interbank Offered Rate (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 Net Interest Coverage Ratio (Consolidated EBITDA to Consolidated Net 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 minimum Consolidated Net Interest Coverage Ratio of 3.5:1.0 as of the last day of any fiscal quarter. As of December 31, 2024, no borrowings were outstanding under the Facility, although available capacity was reduced by immaterial 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.
Senior Notes
Interest is payable annually on the euro and Swiss franc-denominated fixed rate senior notes and semi-annually on all other senior notes. Each of the U.S. dollar, euro-denominated fixed rate senior notes and yen-denominated private placement notes may be redeemed at a redemption price of 100% of the principal amount plus a specified make-whole premium and accrued interest, together with swap breakage costs payable to holders of yen-denominated private placement notes who have entered into cross-currency swap agreements. The company is subject to certain affirmative and negative covenants under the indentures and note purchase agreement governing the senior notes, the most restrictive of which limits the ability of the company to pledge certain property and assets as security under borrowing arrangements. The company was in compliance with all covenants related to its senior notes at December 31, 2024.
In 2022 the company completed the full allocation of an amount equal to the net proceeds from the 0.000% senior notes due 2025 to finance or refinance, in whole or in part, certain COVID-19 response projects.
In 2022, the company redeemed all of its 3.650% Senior Notes due 2025. In connection with the redemption, the company incurred $26 million of losses on the early extinguishment of debt included in other income/(expense) on the accompanying statement of income.
Thermo Fisher Scientific (Finance I) B.V. (Thermo Fisher International), a wholly-owned finance subsidiary of the company, issued each of the following notes outstanding as of December 31, 2024, included in the table above (collectively, the “Euronotes”) in registered public offerings: the 0.00% Senior Notes due 2025, the 0.80% Senior Notes due 2030, the 1.125% Senior Notes due 2033, the 1.625% Senior Notes due 2041, and the 2.00% Senior Notes due 2051. The company has fully and unconditionally guaranteed all of Thermo Fisher International’s obligations under the Euronotes and all of Thermo Fisher International’s other debt securities, and no other subsidiary of the company will guarantee these obligations. Thermo Fisher International is a “finance subsidiary” as defined in Rule 13-01(a)(4)(vi) of the Exchange Act, with no assets or operations other than those related to the issuance, administration and repayment of the Euronotes and other debt securities issued by Thermo Fisher International from time to time. The financial condition, results of operations and cash flows of Thermo Fisher International are consolidated in the financial statements of the company.

Fair Value Measurements
The company uses the market approach technique to value its financial instruments and there were no changes in valuation techniques during 2024. The company’s financial assets and liabilities carried at fair value are primarily comprised of investments in bank time deposits, publicly traded securities, insurance contracts, investments in derivative contracts, mutual funds holding publicly traded securities and other investments in unit trusts held as assets to satisfy outstanding deferred compensation and retirement liabilities; and acquisition-related contingent consideration.
The following tables present information about the company’s financial assets and liabilities measured at fair value on a recurring basis:

Commitments and Contingencies
12 Months Ended
Dec. 31, 2024
Commitments and Contingencies Disclosure [Abstract]  
Commitments and Contingencies Commitments and Contingencies
Purchase Obligations
The company has entered into unconditional purchase obligations, in the ordinary course of business, that include agreements to purchase goods, services or fixed assets and to pay royalties that are enforceable and legally binding and that specify all significant terms including: fixed or minimum quantities to be purchased; fixed, minimum or variable price provisions; and the approximate timing of the transaction. Purchase obligations exclude agreements that are cancelable at any time without penalty. The aggregate amount of the company’s unconditional purchase obligations totaled $2.20 billion at December 31, 2024, the majority of which are expected to be settled during 2025.
Letters of Credit, Guarantees and Other Commitments
Outstanding letters of credit and bank guarantees totaled $335 million at December 31, 2024. Substantially all of these letters of credit and guarantees expire before 2040.
Outstanding surety bonds and other guarantees totaled $123 million at December 31, 2024. The expiration of these bonds and guarantees ranges through 2028.
The letters of credit, bank guarantees and surety bonds principally secure performance obligations, and allow the holder to draw funds up to the face amount of the letter of credit, bank guarantee or surety bond if the applicable business unit does not perform as contractually required.
The company has funding commitments totaling $182 million at December 31, 2024, related to investments.
The company is a guarantor of pension plan obligations of a divested business. The purchaser of the divested business has agreed to pay for the pension benefits; however, the company was required to guarantee payment of these pension benefits should the purchaser fail to do so. The amount of the guarantee at December 31, 2024 was $25 million.
In connection with the sale of businesses of the company, the buyers have assumed certain contractual obligations of such businesses and have agreed to indemnify the company with respect to those assumed liabilities. In the event a third-party to a transferred contract does not recognize the transfer of obligations or a buyer defaults on its obligations under the transferred contract, the company could be liable to the third-party for such obligations. However, in such event, the company would be entitled to seek indemnification from the buyer.
Indemnifications
In conjunction with certain transactions, primarily divestitures, the company has agreed to indemnify the other parties with respect to certain liabilities related to the businesses that were sold or leased properties that were abandoned (e.g., retention of certain environmental, tax, employee and product liabilities). The scope and duration of such indemnity obligations vary from transaction to transaction. Where probable, an obligation for such indemnifications is recorded as a liability. Generally, a maximum obligation cannot be reasonably estimated. Other than obligations recorded as liabilities at the time of divestiture, historically the company has not made significant payments for these indemnifications.
In connection with the company’s efforts to reduce the number of facilities that it occupies, the company has vacated some of its leased facilities or sublet them to third parties. When the company sublets a facility to a third-party, it remains the primary obligor under the master lease agreement with the owner of the facility. As a result, if a third-party vacates the sublet facility, the company would be obligated to make lease or other payments under the master lease agreement. The company believes that the financial risk of default by sublessors is individually and in the aggregate not material to the company’s financial position or results of operations.
In connection with the sale of products in the ordinary course of business, the company often makes representations affirming, among other things, that its products do not infringe on the intellectual property rights of others and agrees to indemnify customers against third-party claims for such infringement. The company has not been required to make material payments under such provisions.
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. At December 31, 2024, the company’s total environmental
liability was approximately $81 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 and cash flows.
Litigation and Related Contingencies
The company is involved in various disputes, governmental and/or regulatory inspections, inquiries, investigations and proceedings, and litigation matters that arise from time to time in the ordinary course of business. The disputes and litigation matters include product liability, intellectual property, employment and commercial issues. 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, 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
The company is involved in various proceedings and litigation that arise from time to time in connection with product liability, workers compensation and other personal injury matters. The range of probable loss for product liability, workers compensation and other personal injury matters of the company’s continuing operations at December 31, 2024, was approximately $224 million to $381 million. The company’s accrual for these matters totaled $225 million at December 31, 2024. The accrual includes estimated defense costs and is gross of estimated amounts due from insurers of $83 million at December 31, 2024 that are included in other assets in the accompanying balance sheet. In addition, as of December 31, 2024, the company had a product liability accrual of $21 million relating to divested businesses.
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, which could have a material adverse effect on the company’s results of operations, financial position, and cash flows. 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.

Restructuring and Other Costs
Restructuring and other costs in 2024 primarily included continuing charges for headcount reductions and facility consolidations in an effort to streamline operations, impairment of long-lived assets, and, to a lesser extent, net charges for pre-acquisition litigation and other matters. In 2024 severance actions associated with facility consolidations and cost reduction measures affected approximately 2% of the company’s workforce.
Restructuring and other costs in 2023 primarily included continuing charges for headcount reductions and facility consolidations in an effort to streamline operations, impairment of long-lived assets, and, to a lesser extent, net charges for pre-acquisition litigation and other matters. In 2023, severance actions associated with facility consolidations and cost reduction measures affected approximately 5% of the company’s workforce.
Restructuring and other costs in 2022 primarily included impairment of long-lived assets and continuing charges for headcount reductions and facility consolidations in an effort to streamline operations. In 2022, severance actions associated with facility consolidations and cost reduction measures affected less than 2% of the company’s workforce.
As of February 20, 2025, the company has identified restructuring actions, primarily in the Laboratory Products and Biopharma Services segment, that it expects will result in additional charges of approximately $200 million, primarily in 2025, and expects to identify additional actions in future periods.

The company has operations and a taxable presence in approximately 70 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, non-deductible interest in certain foreign jurisdictions, and foreign taxes that are different than the U.S. federal statutory rate.
During 2024, the company recorded a tax reserve and associated interest of $240 million related to the settlement of international tax audits for tax years 2009 through 2016, which were settled in 2024. The company also recorded tax benefits of $459 million, primarily in jurisdictions where the deferred tax assets are now expected to be realized due to forecasted income. The benefits were partially offset by tax provisions primarily associated with disallowed interest expense and net operating loss carryforwards that are not expected to be realized.
During 2023, the company released valuation allowances of $32 million in jurisdictions where the deferred tax assets are now expected to be realized. In 2023 the company also recorded a tax benefit of $127 million for U.S. tax credits and the revaluation of net operating loss carryforwards due to higher tax rates as a result of its tax return resubmissions, a $91 million tax benefit, net of related tax expenses, from a foreign exchange loss on an intercompany debt refinancing transaction, and $233 million of tax benefits resulting from intra-entity transactions.
During 2022, the company settled an IRS audit relating to the 2017 and 2018 tax years. The company recorded a $208 million net tax benefit primarily from this settlement and related impacts, which resulted in a decrease in the company’s unrecognized tax benefits of $658 million. The company recorded $49 million of charges for expired tax credits and other related components of the settlement. The company recorded a charge of $395 million to establish a valuation allowance against certain U.S. foreign tax credits which the company believes will more likely than not expire unutilized. The company also recorded $101 million of additional net unrecognized tax benefit liabilities related to other tax audits.
The company generally receives a tax deduction upon the exercise of non-qualified stock options by employees, or the vesting of restricted stock units held by employees, for the difference between the exercise price and the market price of the underlying common stock on the date of exercise. The company uses the incremental tax benefit approach for utilization of tax attributes. These excess tax benefits reduce the tax provision. In 2024, 2023 and 2022, the company's tax provision was reduced by $67 million, $69 million and $80 million, respectively, of such benefits.

The company estimates the degree to which tax assets, losses and credit carryforwards will result in a benefit based on expected profitability by tax jurisdiction and provides a valuation allowance for tax assets and loss and credit carryforwards that it believes will more likely than not expire unutilized. At December 31, 2024, all of the company’s valuation allowance relates to deferred tax assets, primarily net operating losses and disallowed interest expense carryforward, for which any subsequently recognized tax benefits will reduce income tax expense.
The changes in the valuation allowance are as follows:

At December 31, 2024, the company had net federal, state and non-U.S. net operating loss carryforwards of $109 million, $63 million and $1.54 billion, respectively. Use of the carryforwards is limited based on the future income of certain subsidiaries. Of the federal net operating loss carryforwards, $43 million expire in the years 2025 through 2037, and the remainder do not expire. Of the state net operating loss carryforwards, $54 million expire in the years 2025 through 2043, and the remainder do not expire. Of the net non-U.S. net operating loss carryforwards, $574 million expire in the years 2027 through 2044, and the remainder do not expire.
At December 31, 2024, the company had foreign tax credit carryforwards of $729 million and deferred interest carryforwards of $534 million. The foreign tax credit carryforwards will expire in the years 2025 through 2034. Of the deferred interest carryforwards, $201 million expire in the years 2025 through 2034 and the remainder do not expire.
U.S. federal taxes have been recorded on approximately $40 billion of undistributed foreign earnings as of December 31, 2024. A provision has not been made for certain U.S. state income taxes or additional non-U.S. taxes that would be due when cash is repatriated to the U.S. as the company’s undistributed foreign earnings are intended to be reinvested outside of the U.S. indefinitely. The determination of the amount of the unrecognized deferred tax liability related to the undistributed foreign earnings is not practicable due to the uncertainty in the manner in which these earnings will be distributed. The company’s intent is to only make distributions from non-U.S. subsidiaries in the future when they can be made at no net tax cost.
Unrecognized Tax Benefits
As of December 31, 2024, the company had $0.52 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:

Substantially all of the unrecognized tax benefits are classified as long-term liabilities. The company does not expect its unrecognized tax benefits to change significantly over the next twelve months.
During 2024, the company’s unrecognized tax benefits decreased by $99 million as a result of uncertain tax positions relating to foreign tax positions which included $240 million of reserve and associated interest from the settlement of international tax audits for tax years 2009 through 2016 and increased $84 million relating to U.S. federal and state tax positions.
During 2023, the company’s unrecognized tax benefits decreased by $12 million as a result of uncertain tax positions relating to foreign tax positions and decreased $19 million relating to U.S. federal and state tax positions.
During 2022, the company’s unrecognized tax benefits increased by $143 million as a result of uncertain tax positions relating to foreign tax positions and decreased $610 million relating to U.S. federal and state tax positions which included $658 million from the settlement of the IRS audit of the 2017 and 2018 tax years. The company also assumed $15 million of uncertain tax benefits as part of the acquisition of PPD.
The company classified interest and penalties related to unrecognized tax benefits as income tax expense. The total amount of interest and penalties related to uncertain tax positions and recognized in the balance sheet as of December 31, 2024 and 2023 was $75 million and $95 million, respectively.
The company conducts business globally and, as a result, Thermo Fisher or one or more of its subsidiaries files income tax returns in the U.S. federal jurisdiction and various state and foreign jurisdictions. In the normal course of business, the company is subject to examination by taxing authorities throughout the world, including such major jurisdictions as Australia, Canada, China, Denmark, Finland, France, Germany, Japan, Singapore, Sweden, the United Kingdom and the United States. With few exceptions, the company is no longer subject to U.S. state and local or non-U.S. income tax examinations for years before 2012 and no longer subject to U.S. federal income tax examinations for years before 2019.

The company uses foreign currency-denominated debt, certain foreign currency-denominated payables, and cross-currency interest rate swaps to partially hedge its net investments in foreign operations against adverse movements in exchange rates. A portion of the company’s euro-denominated senior notes, certain foreign currency-denominated payables, and 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 certain foreign currency-denominated payables, 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 segment also includes a comprehensive offering of outsourced services used by the pharmaceutical and biotech industries for drug development, clinical research, clinical trials services and commercial drug manufacturing.
The company’s management evaluates segment operating performance based on operating income before certain charges/credits to cost of revenues and selling, general and administrative expenses, restructuring and other costs, 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 facilitates comparison of performance for determining compensation.
The company's president, chairman and chief executive officer is its chief operating decision maker (CODM). The CODM uses total revenues and segment income predominantly in the strategic plan, annual operating plan and quarterly business review processes. During these processes, the CODM considers budget-to-actual variances to evaluate both internal (e.g., changes in selling prices, strategic growth investments, productivity, business mix, newly acquired/divested businesses, etc.) and external (e.g., inflation, foreign currency, etc.) events and conditions.
The company generally accounts for intersegment revenues at current market prices.
Other segment items included in the below tables consist of stock-based compensation and other incentive compensation expenses, allocations of corporate expenses and certain overhead expenses as well as elimination of intersegment and intrasegment profits, all of which are included in the company's measurement of segment income, but not regularly provided to the CODM at the segment level. Cost of revenues adjustments consist of charges for the sale of inventories revalued at the date of acquisition, inventory write-downs associated with large-scale abandonments of product lines, and accelerated depreciation on fixed assets to estimated salvage value in connection with the consolidation of operations. Selling, general and administrative adjustments consist of significant transaction/integration costs (including reimbursement thereof) related to recent/terminated acquisitions, charges/credits for changes in estimates of contingent acquisition consideration, and charges related to product liability litigation. Restructuring and other costs include charges arising from headcount reductions and facility consolidations such as severance and abandoned lease expense and gains and losses on the sale of real estate and
product lines, as well as impacts of pre-acquisition matters and net charges for significant litigation-related matters (Note 6).
Segment assets included in the below tables consist of third-party accounts receivable and inventories, which are regularly provided to the CODM.
Geographical revenues are attributed to countries based on customer location. Long-lived assets by geographical location includes property, plant and equipment, net, and operating lease ROU assets.

Business Combination, Asset Acquisition, and Joint Venture Formation [Abstract]  
Acquisitions Acquisitions
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 and the benefits that will be gained from the assembled workforces. 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 services; and use of the commercial infrastructure of the acquired businesses to cost-effectively expand sales of company products and services.
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.

These operating leases generally have remaining lease terms between 1 month and 30 years, and some include options to extend (generally for 1 to 10 years) or have options to terminate the arrangement within 1 year.
The company has guaranteed the residual value of three leased operating facilities with lease terms ending in 2025, and 2028, and 2029. The company has agreed with the lessor to comply with certain financial covenants consistent with its other debt arrangements (Note 3). The aggregate maximum guarantee under these three lease arrangements is $147 million. Operating lease ROU assets and lease liabilities for these lease arrangements are recorded on the consolidated balance sheet as of December 31, 2024, but exclude any amounts for residual value guarantees.

Pension and Other Postretirement Benefit Plans Pension and Other Postretirement Benefit Plans
401(k) Savings Plan and Other Defined Contribution Plans
The company’s 401(k) savings and other defined contribution plans cover the majority of the company’s eligible U.S. and certain non-U.S. employees. Contributions to the plans are made by both employees and the company. Company contributions are based on the level of employee contributions and formulas determined by the company. In 2024, 2023 and 2022, the company charged to expense $443 million, $468 million and $402 million, respectively, related to its defined contribution plans.
Defined Benefit Pension Plans
Employees of a number of the company’s non-U.S. and certain U.S. subsidiaries participate in defined benefit pension plans covering substantially all full-time employees at those subsidiaries. Some of the plans are unfunded, as permitted under the plans and applicable laws. The company also maintains postretirement healthcare programs at several acquired businesses where certain employees are eligible to participate. The liabilities and costs associated with the company’s postretirement healthcare programs are generally funded on a self-insured and insured-premium basis and are not material for any period presented.
Contributions to the plans included in the following table are estimated at between $40 million and $50 million for 2025.
The following table provides a reconciliation of benefit obligations and plan assets of the company’s domestic and non-U.S. pension plans:

Actuarial (gains)/losses experienced in 2024 for both domestic and non-U.S. pension plans were primarily driven by increases in the weighted average discount rates used to determine the projected benefit obligation when compared to 2023.
For domestic pension plans, actuarial (gains)/losses experienced in 2023 were driven by decreases in the weighted average discount rates used to determine the projected benefit obligation, as well as differences between actual and expected returns on plan assets for certain portions of plan benefits indexed to asset returns. For non-U.S. pension plans, actuarial (gains)/losses experienced in 2023 were principally driven by decreases in the weighted average discount rates used to determine the projected benefit obligation.
The actuarial assumptions used to compute the funded status for the plans are based upon information available as of December 31, 2024 and 2023 and are as follows:

Expected benefit payments are estimated using the same assumptions used in determining the company’s benefit obligation at December 31, 2024. Benefit payments will depend on future employment and compensation levels, average years employed and average life spans, among other factors, and changes in any of these factors could significantly affect these estimated future benefit payments.

Domestic Pension Plan Assets
The company’s overall objective is to manage the assets in a liability framework where investments are selected that are expected to have similar changes in fair value as the related liabilities will have upon changes in interest rates. The company invests in a portfolio of both return-seeking and liability-hedging assets, primarily through the use of institutional collective funds, to achieve long-term growth and to insulate the funded position from interest rate volatility. The strategic asset allocation uses a combination of risk controlled and index strategies in fixed income and global equities. The target allocations for the investments are approximately 10% to funds investing in U.S. equities, approximately 10% to funds investing in international equities and approximately 80% to funds investing in fixed income securities. The portfolio maintains enough liquidity at all times to meet the near-term benefit payments.
Non-U.S. Pension Plan Assets
The company maintains specific plan assets for many of the individual pension plans outside the U.S. The investment strategy of each plan has been uniquely established based on the country specific standards and characteristics of the plans. Several of the plans have contracts with insurance companies whereby the market risks of the benefit obligations are borne by the insurance companies. When assets are held directly in investments, generally the objective is to invest in a portfolio of diversified assets with a variety of fund managers. The investments may include equity funds, fixed income funds, hedge funds, multi-asset funds, alternative investments, real estate funds and derivative funds with the target asset allocations ranging from approximately 0% - 25% for equity funds, 30% - 90% for fixed income funds, 0% - 40% for multi-asset funds, 0% - 4% for alternative investments, 0% - 4% for real estate funds and 0% - 45% for funds holding derivatives. The derivatives held by the funds are primarily interest rate swaps intended to match the movements in the plan liabilities. Each plan maintains enough liquidity at all times to meet the near-term benefit payments.

Share-Based Payment Arrangement [Abstract]  
Stock-based Compensation Expense Stock-based Compensation Expense
The company has stock-based compensation plans for its key employees, directors and others. These plans permit the grant of a variety of stock and stock-based awards, including restricted stock units, stock options or performance-based shares, as determined by the compensation committee of the company’s Board of Directors or, for certain non-officer grants, by the company’s employee equity committee, which consists of its chief executive officer. The company generally issues new shares of its common stock to satisfy option exercises and restricted unit vesting. Grants of stock options and restricted units generally provide that in the event of both a change in control of the company and a qualifying termination of an option or unit holder’s employment, all options and service-based restricted unit awards held by the recipient become immediately vested (unless an employment or other agreement with the employee provides for different treatment).

Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]
Cybersecurity Risk Management and Strategy
As is the case for most large global companies, we are regularly subject to cyberattacks and other cybersecurity incidents and, therefore, we incorporate cybersecurity into our overall risk management process. Our commitment to cybersecurity emphasizes using a risk-based, “defense in depth” approach to assess, educate, block, identify, respond to and recover from cybersecurity threats. Recognizing that no single technology, process or control can effectively prevent or mitigate all risks, we employ a strategy of technologies, processes and controls, all working independently but as part of a cohesive strategy to manage or reduce risk.
Our cybersecurity program assists in the management of risks associated with the confidentiality, integrity and availability of data and systems within the company environment to effectively support our business objectives and customer expectations. The program provides guidance to business stakeholders on cybersecurity risks as input into their risk management processes that balance cybersecurity risk with other important risks that may include strategic, regulatory, economic and financial considerations.
We seek to routinely refine our cybersecurity approach to adapt to changes in the threat landscape and manage emerging security risks. In order to evaluate risks from cybersecurity threats associated with the company’s use of certain third-party technology providers, we have incorporated a risk-based assessment into the corporate information technology (IT) procurement process designed to assess the security risk of certain third parties providing new technology solutions to our environment.
We believe cybersecurity is the responsibility of every employee, and regularly educate and share best practices with our employees to raise awareness of cybersecurity threats through a security awareness training program, including regular exercises, periodic cyber-event simulations and annual attestation to our Technology Acceptable Use Policy.
We do not reasonably believe there are currently any cybersecurity incidents that have materially affected or are reasonably likely to materially affect the company or its business strategy, results of operations or financial condition. For more information on the risks related to our IT systems, see “A significant disruption in, or breach in security of, our IT systems or violation of data privacy laws could adversely affect our business or customers that use our products” under the heading “Risk Factors” in Part I, Item 1A.

Organization, Consolidation and Presentation of Financial Statements [Abstract]  
Principles of Consolidation and Redeemable Noncontrolling Interest
Principles of Consolidation
The accompanying financial statements include the accounts of the company and its wholly and majority-owned subsidiaries. All material intercompany accounts and transactions have been eliminated.
Redeemable Noncontrolling Interest
The company owns 60% of its consolidated subsidiary PPD-SNBL K.K. The 40% ownership interest held by a third party is classified as a redeemable noncontrolling interest on the consolidated balance sheet due to certain put options under which the third party may require the company to purchase the remaining ownership interest at a premium upon the occurrence of certain events.
Presentation
Presentation
Certain reclassifications of prior year amounts have been made to conform to the current year presentation.
Amounts and percentages reported within these consolidated financial statements are presented and calculated based on underlying unrounded amounts. As a result, the sum of components may not equal corresponding totals due to rounding.
Use of Estimates
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. Actual results could differ from those estimates.
Cash and Cash Equivalents
Cash and Cash Equivalents
Cash equivalents consists principally of money market funds and other marketable securities purchased with a remaining maturity of three months or less. These investments are carried at cost, which approximates market value (see Note 4).
Inventories
Inventories
Inventories are valued at the lower of cost or net realizable value, cost being determined by the first-in, first-out (FIFO) method. The company periodically reviews quantities of inventories on hand and compares these amounts to the expected use of each product or product line. In addition, the company has certain inventory that is subject to fluctuating market pricing. The company records a charge to cost of sales for the amount required to reduce the carrying value of inventory to net realizable value. Costs associated with the procurement of inventories, such as inbound freight charges, purchasing and receiving costs, and internal transfer costs, are included in cost of revenues in the accompanying statement of income.
Contract-related Balances
Contract-related Balances
Accounts receivable include unconditional rights to consideration from customers, which generally represent billings that 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.
Revenue Recognition
Contract assets include revenues recognized in advance of billings where the company’s right to bill includes something other than the passage of time. Such amounts 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.
Contract liabilities include billings in excess of revenues recognized, such as those resulting from customer advances and deposits and unearned revenues on service contracts. Contract liabilities are classified as current or noncurrent based on the periods over which remaining performance obligations are expected to be transferred to customers. 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.
Noncurrent contract assets and noncurrent contract liabilities are included within other assets and other long-term liabilities in the accompanying balance sheet, respectively (see Note 2).
Revenue Recognition
Consumables revenues consist of single-use products and are recognized at a point in time following the transfer of control of such products to the customer, which generally occurs upon shipment. Instruments revenues typically consist of longer-lived assets that, for the substantial majority of sales, are recognized at a point in time in a manner similar to consumables. Service revenues (primarily clinical research, pharmaceutical, and instrument and enterprise services) are recognized over time as customers receive and consume the benefits of such services. For revenues recognized over time, the company generally uses costs accumulated relative to total estimated costs to measure progress as this method approximates satisfaction of the performance obligation. For contracts that contain multiple performance obligations, the company allocates the consideration to which it expects to be entitled (i.e., the transaction price) to each performance obligation based on relative standalone selling prices and recognizes the related revenues when or as control of each individual performance obligation is transferred to customers. The company exercises judgment in determining the timing of revenue by analyzing the point in time or the period over which the customer has the ability to direct the use of and obtain substantially all of the remaining benefits of the asset. The company immediately expenses contract costs that would otherwise be capitalized and amortized over a period of less than one year.
Changes to the scope of services contracts generally also include changes in the transaction price. Typically, these contract modifications are not distinct from existing services provided under the contract, and result in cumulative adjustments to revenue on the modification date. However, some modifications are distinct from existing services provided under the contract and recognized prospectively.
Payments from customers for most instruments and consumables are typically due in a fixed number of days after shipment or delivery of the product. Service arrangements commonly call for payments in advance of performing the work (e.g., extended service contracts), upon completion of the service (e.g., pharmaceutical services) or a mix of both. Some arrangements include variable amounts of consideration that arise from discounts, rebates, and other programs and practices. In such arrangements, the company estimates the amount by which to reduce the stated contract amount to reflect the transaction price. The company records reimbursement for third-party pass-through and out-of-pocket costs as revenues and the related expenses as costs of revenues.
Property, Plant and Equipment
Property, Plant and Equipment
Property, plant and equipment are recorded at cost. The costs of additions and improvements are capitalized, while maintenance and repairs are charged to expense as incurred. The company generally provides for depreciation and amortization using the straight-line method over the estimated useful lives of the property as follows: buildings and improvements, 25 to 40 years; machinery and equipment (including software), 3 to 10 years; and leasehold improvements, the shorter of the term of the lease or the life of the asset. When assets are retired or otherwise disposed of, the assets and related accumulated depreciation are eliminated from the accounts and the resulting gain or loss is reflected in the accompanying statement of income.
Acquisition-related Intangible Assets
Acquisition-related Intangible Assets
Acquisition-related intangible assets include the costs of acquired customer relationships, product technology, tradenames, backlog and other specifically identifiable intangible assets, and are being amortized using the straight-line method over their estimated useful lives, which range up to 20 years. The company reviews these intangible assets for impairment when indication of potential impairment exists, such as a significant reduction in cash flows associated with the assets. When impairment indicators exist, the company determines whether the carrying value of its intangible assets exceeds the related undiscounted cash flows. In these situations, the carrying value is written down to fair value.
In addition, the company has tradenames that have indefinite lives and which are not amortized. Intangible assets with indefinite lives are reviewed for impairment annually or whenever events or changes in circumstances indicate they may be impaired. The company may perform an optional qualitative assessment. If the company determines that the fair value of the indefinite-lived intangible asset is more likely than not greater than its carrying amount, no additional testing is necessary. If not, or if the company bypasses the optional qualitative assessment, it writes the carrying value down to the fair value, if applicable.
Investments
Investments
Investments include marketable securities, such as marketable equity securities, available for sale debt securities, and bank time deposits with maturities greater than three months, equity method investments, and non-marketable equity investments. The company classifies investments as current or noncurrent based on the nature of the securities and their availability for use in current operations. Noncurrent investments are included in other assets.
Marketable securities are stated at fair value with all realized and unrealized gains and losses on investments in marketable equity securities and realized gains and losses on available-for-sale debt securities recognized in other income/(expense).
The company accounts for investments in businesses using the equity method when it has the ability to exercise significant influence but not control (generally between 20% and 50% ownership), is not the primary beneficiary and has not elected the fair value option. The company has elected the fair value option of accounting for certain of its investments with readily determinable fair values that would otherwise be accounted for under the equity method (see Note 2). The company’s share of gains and losses in, and impairments of, equity method investments are recorded in equity in earnings (losses) of unconsolidated entities. Equity investments that do not have readily determinable fair values and are not eligible for the net asset value (NAV) practical expedient are measured at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or similar investments of the same issuer. The company performs qualitative assessments to identify impairments of these investments. All gains and losses on non-equity method investments are recognized in other income/(expense).
Goodwill
Goodwill
The company assesses goodwill for impairment at the reporting unit level annually and whenever events occur or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. Such events or circumstances generally include the occurrence of operating losses or a significant decline in earnings associated with one or more of the company’s reporting units. The company is permitted to first assess qualitative factors to determine whether the quantitative goodwill impairment test is necessary. If the qualitative assessment results in a determination that the fair value of a reporting unit is more likely than not less than its carrying amount, the company performs a quantitative goodwill impairment test. The company may bypass the qualitative assessment for the reporting unit in any period and proceed directly to the quantitative goodwill impairment test. The company estimates the fair value of its reporting units by using forecasts of discounted future cash flows and peer market multiples. The company would record an impairment charge based on the excess of a reporting unit’s carrying amount over its fair value (limited to the amount of goodwill). The company determined that no impairments existed in 2024, 2023 or 2022.
Fair Value Measurements
Fair Value Measurements
Assets and liabilities carried at fair value are classified and disclosed in one of the following three categories:
Level 1: Quoted market prices in active markets for identical assets or liabilities that the company has the ability to access.
Level 2: Observable market based inputs or unobservable inputs that are corroborated by market data such as quoted prices, interest rates and yield curves.
Level 3: Inputs are unobservable data points that are not corroborated by market data.
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 initially measures the fair value of acquisition-related contingent consideration based on amounts expected to be transferred (probability-weighted) discounted to present value. Changes to the fair values of contingent consideration are recorded in selling, general and administrative expense. The company determines the fair value of its equity method and non-marketable equity investments that are not eligible for the NAV practical expedient by considering factors such as financial position, operating results and cash flows of the investee; recent transactions in the same or similar securities; significant recent events affecting the investee; the price paid by Thermo Fisher; among others.
Loss Contingencies
Loss Contingencies
Accruals are recorded for various contingencies, including legal proceedings, environmental, workers’ compensation, product, general and auto liabilities, self-insurance and other claims that arise in the normal course of business. The accruals are based on management’s judgment, historical claims experience, the probability of losses and, where applicable, the consideration of opinions of internal and/or external legal counsel and actuarial estimates. Additionally, the company records receivables from third-party insurers up to the amount of the loss when recovery has been determined to be probable.
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.
The company determines the probability and range of possible loss for its litigation and other contingencies 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.
Warranty Obligations
Warranty Obligations
The company provides for the estimated cost of standard product warranties, primarily from historical information, in cost of product revenues at the time product revenues are recognized. The liability for warranties is included in other accrued expenses in the accompanying balance sheet. Extended warranty agreements are considered service contracts, which are discussed above. Costs of service contracts are recognized as incurred.
Foreign Currency Translation
Foreign Currency Translation
All assets and liabilities of the company’s subsidiaries operating in non-U.S. dollar currencies are translated at period-end exchange rates. Resulting translation adjustments are reflected in the “accumulated other comprehensive items” component of shareholders’ equity. Revenues and expenses are translated at average exchange rates for the period.
Research and Development
Research and Development
The company conducts research and development activities to increase its depth of capabilities in technologies, software and services. Research and development costs include employee compensation and benefits, consultants, facilities related costs, material costs, depreciation and travel. Research and development costs are expensed as incurred.
Restructuring Costs
Restructuring Costs
Accounting for the timing and amount of termination benefits provided by the company to employees is determined based on whether: (a) the company has a substantive plan to provide such benefits, (b) the company has a written employment contract with the affected employees that includes a provision for such benefits, (c) the termination benefits are due to the occurrence of an event specified in an existing plan or agreement, or (d) the termination benefits are a one-time benefit. In certain circumstances, employee termination benefits may meet more than one of the characteristics listed above and therefore, may have individual elements that are subject to different accounting models.
From time to time when executing a restructuring or exit plan, the company also incurs costs other than termination benefits, such as lease termination costs, that are not associated with or will not be incurred to provide economic benefits to the company. These include costs that represent amounts under contractual obligations that exist prior to the restructuring plan communication date and will either continue after the restructuring plan is completed with no economic benefit or result in a penalty to cancel a contractual obligation. Such costs are recognized when incurred, which generally occurs at the contract termination or over the period from when a plan to abandon a leased facility is approved through the cease-use date but charges may continue over the remainder of the original contractual period.
Earnings per Share
Earnings per Share
Basic earnings per share has been computed by dividing net income attributable to Thermo Fisher Scientific Inc. by the weighted average number of shares outstanding during the year. Except where the result would be antidilutive to net income
attributable to Thermo Fisher Scientific Inc., diluted earnings per share has been computed using the treasury stock method for outstanding stock options and restricted units (see Note 6).
Income Taxes
Income Taxes
The company recognizes deferred income taxes based on the expected future tax consequences of differences between the financial statement basis and the tax basis of assets and liabilities, calculated using enacted tax rates in effect for the year in which the differences are expected to be reflected in the tax return. A valuation allowance is provided for tax assets that will more likely than not go unused.
The financial statements reflect expected future tax consequences of uncertain tax positions that the company has taken or expects to take on a tax return presuming the taxing authorities’ full knowledge of the positions and all relevant facts, but without discounting for the time value of money (see Note 7).
Derivatives Contracts
Derivative Contracts
The company is exposed to certain risks relating to its ongoing business operations including changes to interest rates and currency exchange rates. The company uses derivative instruments primarily to manage currency exchange and interest rate risks. The company recognizes derivative instruments as either assets or liabilities and measures those instruments at fair value. If a derivative is a hedge, depending on the nature of the hedge, changes in the fair value of the derivative are either offset against the change in fair value of the hedged item through earnings or recognized in other comprehensive items until the hedged item is recognized in earnings. Derivatives that are not designated as hedges are recorded at fair value through earnings.
The company uses short-term forward and option currency exchange contracts primarily to hedge certain balance sheet and operational exposures resulting from changes in currency exchange rates, predominantly intercompany loans and cash balances that are denominated in currencies other than the functional currencies of the respective operations. The currency-exchange contracts principally hedge transactions denominated in euro, Canadian dollars, British pounds sterling, Swedish krona, Singapore dollars, Hong Kong dollars and Swiss franc. The company does not hold or engage in transactions involving derivative instruments for purposes other than risk management.
Cash flow hedges. For derivative instruments that are designated and qualify as a cash flow hedge, the gain or loss on the derivative is reported as a component of other comprehensive items and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings and is presented in the same income statement line item as the earnings effect of the hedged item.
Fair value hedges. For derivative instruments that are designated and qualify as a fair value hedge, the gain or loss on the derivative, as well as the offsetting loss or gain on the hedged item attributable to the hedged risk, are recognized in earnings.
Net investment hedges. The company uses foreign currency-denominated debt, certain foreign currency-denominated payables, and cross-currency interest rate swaps to partially hedge its net investments in foreign operations against adverse movements in exchange rates. A portion of the company’s euro-denominated senior notes, certain foreign currency-denominated payables, and 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 certain foreign currency-denominated payables, 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 fair value of the cross-currency interest rate swaps is included in the accompanying balance sheets under the caption other assets or other long-term liabilities. The fair value of the currency exchange contracts is included in the accompanying balance sheets under the captions other current assets or other accrued expenses.
Leases
Leases
Operating leases that have commenced are included in other assets, other accrued expenses and other long-term liabilities in the consolidated balance sheet. Finance leases that have commenced are included in property, plant and equipment, net, current maturities of long-term obligations and long-term obligations in the consolidated balance sheet. Classification of lease liabilities as either current or noncurrent is based on the expected timing of payments due under the company’s obligations.
Right-of-use (ROU) assets represent the company’s right to use an underlying asset for the lease term and lease liabilities represent the company’s obligation to make lease payments arising from the lease. Lease ROU assets and liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. Leases with an initial term of 12 months or less are not recorded on the consolidated balance sheet. The company recognizes operating lease
expense on a straight-line basis over the lease term. Finance lease expense includes depreciation, which is recognized on a straight-line basis over the expected life of the leased asset, and an immaterial amount of interest expense.
Because most of the company’s leases do not provide an implicit interest rate, the company estimates incremental borrowing rates based on the information available at the commencement date in determining the present value of lease payments. The company uses the implicit rate when readily determinable. Lease terms include the effect of options to extend or terminate the lease when it is reasonably certain that the company will exercise that option.
As a lessee, the company accounts for the lease and non-lease components as a single lease component (see Note 13).
Pension and Other Postretirement Benefit Plans
Pension and Other Postretirement Benefit Plans
The company recognizes the funded status of defined benefit pension and other postretirement benefit plans as an asset or liability. This amount is defined as the difference between the fair value of plan assets and the benefit obligation. The company is required to recognize as a component of other comprehensive items, net of tax, the actuarial gains/losses and prior service costs/credits that arise but were not previously required to be recognized as components of net periodic benefit cost/(income). Other comprehensive items is adjusted as these amounts are later recognized in income as components of net periodic benefit cost/(income).
When a company with a pension plan is acquired, any excess of projected benefit obligation over the plan assets is recognized as a liability and any excess of plan assets over the projected benefit obligation is recognized as an asset. The recognition of a new liability or a new asset results in the elimination of (a) previously existing unrecognized net gain or loss and (b) unrecognized prior service cost or credits.
The company funds annually, at a minimum, the statutorily required minimum amount as actuarially determined.
The discount rate used to determine projected benefit obligations and net periodic pension benefit cost/(income) reflects the rate the company would have to pay to purchase high-quality investments that would provide cash sufficient to settle its current pension obligations. The discount rate is determined based on a range of factors, including the rates of return on high-quality, fixed-income corporate bonds and the related expected duration of the obligations or, in certain instances, the company has used a hypothetical portfolio of high quality instruments with maturities that mirror the benefit obligation in order to accurately estimate the discount rate relevant to a particular plan.
The company utilizes a full yield curve approach in the estimation of these components by applying the specific spot-rates along the yield curve used in the determination of the benefit obligation to the relevant projected cash flows.
The expected long-term rate of return on plan assets used to determine net periodic pension benefit cost/(income) reflects the average rate of earnings expected on the funds invested, or to be invested, to provide for the benefits included in the projected benefit obligations. In determining the expected long-term rate of return on plan assets, the company considers the relative weighting of plan assets, the historical performance of total plan assets and individual asset classes and economic and other indicators of future performance. In addition, the company may consult with and consider the opinions of financial and other professionals in developing appropriate return benchmarks.
Asset management objectives include maintaining an adequate level of diversification to reduce interest rate and market risk and providing adequate liquidity to meet immediate and future benefit payment requirements.
The expected rate of compensation increase used to determine net periodic pension benefit cost/(income) reflects the long-term average rate of salary increases and is based on historic salary increase experience and management’s expectations of future salary increases (see Note 14).
Defined Benefit Pension Plans
Employees of a number of the company’s non-U.S. and certain U.S. subsidiaries participate in defined benefit pension plans covering substantially all full-time employees at those subsidiaries. Some of the plans are unfunded, as permitted under the plans and applicable laws. The company also maintains postretirement healthcare programs at several acquired businesses where certain employees are eligible to participate. The liabilities and costs associated with the company’s postretirement healthcare programs are generally funded on a self-insured and insured-premium basis and are not material for any period presented.
Domestic Pension Plan Assets
The company’s overall objective is to manage the assets in a liability framework where investments are selected that are expected to have similar changes in fair value as the related liabilities will have upon changes in interest rates. The company invests in a portfolio of both return-seeking and liability-hedging assets, primarily through the use of institutional collective funds, to achieve long-term growth and to insulate the funded position from interest rate volatility. The strategic asset allocation uses a combination of risk controlled and index strategies in fixed income and global equities. The target allocations for the investments are approximately 10% to funds investing in U.S. equities, approximately 10% to funds investing in international equities and approximately 80% to funds investing in fixed income securities. The portfolio maintains enough liquidity at all times to meet the near-term benefit payments.
Non-U.S. Pension Plan Assets
The company maintains specific plan assets for many of the individual pension plans outside the U.S. The investment strategy of each plan has been uniquely established based on the country specific standards and characteristics of the plans. Several of the plans have contracts with insurance companies whereby the market risks of the benefit obligations are borne by the insurance companies. When assets are held directly in investments, generally the objective is to invest in a portfolio of diversified assets with a variety of fund managers. The investments may include equity funds, fixed income funds, hedge funds, multi-asset funds, alternative investments, real estate funds and derivative funds with the target asset allocations ranging from approximately 0% - 25% for equity funds, 30% - 90% for fixed income funds, 0% - 40% for multi-asset funds, 0% - 4% for alternative investments, 0% - 4% for real estate funds and 0% - 45% for funds holding derivatives. The derivatives held by the funds are primarily interest rate swaps intended to match the movements in the plan liabilities. Each plan maintains enough liquidity at all times to meet the near-term benefit payments.
Stock-based Compensation Expense
Stock-based Compensation Expense
Compensation cost is based on the grant-date fair value and is recognized ratably over the requisite vesting period or to the date based on qualifying retirement eligibility, if earlier, and is primarily included in selling, general and administrative expenses.
The company’s practice is to grant stock options at fair market value. Options vest over 3-5 years with terms of 7-10 years, assuming continued employment with certain exceptions. Vesting of the option awards is contingent upon meeting certain service conditions. The fair value of most option grants is estimated using the Black-Scholes option pricing model. For option grants that require the achievement of both service and market conditions, a lattice model is used to estimate fair value. The fair value is then amortized on a straight-line basis over the requisite service periods of the awards, which is generally the vesting period. Use of a valuation model requires management to make certain assumptions with respect to selected model inputs. Expected volatility is calculated based on the historical volatility of the company’s stock. Historical data on exercise patterns is the basis for estimating the expected life of an option. The risk-free interest rate is based on U.S. Treasury zero-coupon issues with a remaining term which approximates the expected life assumed at the date of grant. The expected annual dividend rate is
calculated by dividing the company’s annual dividend, based on the most recent quarterly dividend rate, by the closing stock price on the grant date. The compensation expense recognized for all stock-based awards is net of estimated forfeitures. Forfeitures are estimated based on an analysis of actual option forfeitures.
Awards of restricted units convert into an equivalent number of shares of common stock. The awards generally vest over 3-4 years, assuming continued employment, with some exceptions. Vesting of the awards is contingent upon meeting certain service conditions and may also be contingent upon meeting certain performance and/or market conditions. The fair market value of the award at the time of the grant is amortized to expense over the requisite service period of the award, which is generally the vesting period. Recipients of restricted units have no voting rights but are entitled to accrue dividend equivalents. The fair value of service- and performance-based restricted unit awards is determined based on the number of units granted and the market value of the company’s shares on the grant date. For awards with market-based vesting conditions, the company uses a lattice model to estimate the grant-date fair value of the award (see Note 15).
Government Assistance
Government Assistance
From time to time, the company receives assistance from various governmental agencies generally in the form of cash or non-income tax credits. These programs help offset the costs of certain research and development activities, facility construction and expansion efforts, or hiring objectives. When the company believes that it is probable that it will meet the conditions tied to the assistance, it offsets the associated expense in the consolidated income statement. Such amounts were not material to the consolidated financial statements as of and for the years ended December 31, 2024, 2023 and 2022.

Business Combinations
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 and the benefits that will be gained from the assembled workforces. 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 services; and use of the commercial infrastructure of the acquired businesses to cost-effectively expand sales of company products and services.
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.

The company estimates the degree to which tax assets, losses and credit carryforwards will result in a benefit based on expected profitability by tax jurisdiction and provides a valuation allowance for tax assets and loss and credit carryforwards that it believes will more likely than not expire unutilized. At December 31, 2024, all of the company’s valuation allowance relates to deferred tax assets, primarily net operating losses and disallowed interest expense carryforward, for which any subsequently recognized tax benefits will reduce income tax expense.
