Accounting Policies [Abstract] |
Use of Estimates | Use of Estimates The preparation of consolidated financial statements in conformity with generally accepted accounting principles (“GAAP”) requires the Company to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent liabilities at the dates of the financial statements. On an ongoing basis, the Company evaluates its estimates, including those related to revenue recognition, goodwill and intangible assets, income taxes, litigation and inventory valuation. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual amounts may differ from these estimates under different assumptions or conditions.
Risks and Uncertainties | Risks and Uncertainties The Company is subject to risks common to companies in the analytical instrument industry, including, but not limited to, global economic and financial market conditions, fluctuations in foreign currency exchange rates, fluctuations in customer demand, development by its competitors of new technological innovations, costs of developing new technologies, levels of debt and debt service requirements, risk of disruption, dependence on key personnel, protection and litigation of proprietary technology, shifts in taxable income between tax jurisdictions and compliance with regulations of the U.S. Food and Drug Administration and similar foreign regulatory authorities and agencies.
Principles of Consolidation | Principles of Consolidation The consolidated financial statements include the accounts of the Company and its subsidiaries, which are wholly owned. The Company consolidates entities in which it owns or controls 50% or more of the voting shares. All inter-company balances and transactions have been eliminated.
Translation of Foreign Currencies | Translation of Foreign Currencies The functional currency of each of the Company’s foreign operating subsidiaries is the local currency of its country of domicile, except for the Company’s subsidiaries in Hong Kong, Singapore and the Cayman Islands, where the underlying transactional cash flows are denominated in currencies other than the respective local currency of domicile. The functional currency of the Hong Kong, Singapore and Cayman Islands subsidiaries is the U.S. dollar, based on the respective entity’s cash flows. For the Company’s foreign operations, assets and liabilities are translated into U.S. dollars at exchange rates prevailing on the balance sheet date, while revenues and expenses are translated at average exchange rates prevailing during the respective period. Any resulting translation gains or losses are included in accumulated other comprehensive loss in the consolidated balance sheets. The Company’s net sales derived from operations outside the United States were 69%, 70% and 72% in 2023, 2022 and 2021, respectively. Gains and losses from foreign currency transactions are included primarily in cost of sales in the consolidated statements of operations. In 2023, 2022 and 2021, foreign currency transactions resulted in net losses of $16 million, $31 million and $5 million, respectively.
Seasonality of Business | Seasonality of Business The Company typically experiences seasonality in its orders that is reflected as an increase in sales in the fourth quarter, as a result of purchasing habits for capital goods of customers that tend to exhaust their spending budgets by calendar year-end.
Cash, Cash Equivalents and Investments | Cash, Cash Equivalents and Investments Cash equivalents represent highly liquid investments, with original maturities of 90 days or less, primarily in bank deposits, U.S. treasury bill money market funds and commercial paper. Investments with longer maturities are classified as investments, and are held primarily in U.S. treasury bills, U.S. dollar-denominated treasury bills and commercial paper, bank deposits and corporate debt securities. Investments are classified as available-for-sale (“AFS”) debt securities. If the AFS debt security’s fair value exceeds the security’s amortized cost the unrealized gain is recognized in accumulated other comprehensive loss in stockholders’ equity (deficit), net of the related tax effects. If the AFS debt security’s fair value declines below its amortized cost the Company considers all available evidence to evaluate the extent to which the decline is due to credit-related factors or noncredit-related factors. If the decline is due to noncredit-related factors then no credit loss is recorded and the unrealized loss is recognized in accumulated other comprehensive income in stockholders’ equity, net of the related tax effects. If the decline is considered to be a credit-related impairment, it is recognized as an allowance on the consolidated balance sheet with a corresponding charge to the statement of operations. The credit allowance is limited to the difference between the fair value and the amortized cost basis. No credit-related allowances or impairments have been recognized on the Company’s investments in available-for-sale debt securities. The Company classifies its investments exclusive of those categorized as cash equivalents. The Company maintains cash balances in various operating accounts in excess of federally insured limits, and in foreign subsidiary accounts in currencies other than the U.S. dollar. As of December 31, 2023 and 2022, $321 million out of $396 million and $472 million out of $481 million, respectively, of the Company’s total cash, cash equivalents and investments were held by foreign subsidiaries. In addition, $233 million out of $396 million and $336 million out of $481 million of cash, cash equivalents and investments were held in currencies other than the U.S. dollar at December 31, 2023 and 2022, respectively.
Accounts Receivable and Allowance for Credit Losses | Accounts Receivable and Allowance for Credit Losses Trade accounts receivable are recorded at the invoiced amount and do not bear interest. The Company has very limited use of rebates and other cash considerations payable to customers and, as a result, the transaction price determination does not have any material variable consideration. The Company does not consider there to be significant concentrations of credit risk with respect to trade receivables due to the short-term nature of the balances, the Company having a large and diverse customer base, and the Company having a strong historical experience of collecting receivables with minimal defaults. As a result, credit risk is considered low across territories and trade receivables are considered to be a single class of financial asset. The allowance for credit losses is based on a number of factors and is calculated by applying a historical loss rate to trade receivable aging balances to estimate a general reserve balance along with an additional adjustment for any specific receivables with known or anticipated issues affecting the likelihood of recovery. Past due balances with a probability of default based on historical data as well as relevant available forward-looking information are included in the specific adjustment. The historical loss rate is reviewed on at least an annual basis and the allowance for credit losses is reviewed quarterly for any required adjustments. The Company does not have any off-balance sheet credit exposure related to its customers. Trade receivables related to instrument sales are collateralized by the instrument that is sold. If there is a risk of default related to a receivable that is collateralized, then the fair value of the collateral is calculated and adjusted for the cost to re-possess, refurbish and re-sell the instrument. This adjusted fair value is compared to the receivable balance and the difference would be recorded as the expected credit loss. The following is a summary of the activity of the Company’s allowance for credit losses for the twelve months ended December 31, 2023, 2022 and 2021 (in thousands):
|  | Balance at Beginning of Period |  |  | Additions |  |  | Deductions |  |  | Balance at End of Period |
Allowance for Credit Losses |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
December 31, 2023 |  | $ | 14,311 |  |  | $ | 8,120 |  |  | $ | (3,096 | ) |  | $ | 19,335 |
December 31, 2022 |  | $ | 13,228 |  |  | $ | 6,509 |  |  | $ | (5,426 | ) |  | $ | 14,311 |
December 31, 2021 |  | $ | 14,381 |  |  | $ | 5,380 |  |  | $ | (6,533 | ) |  | $ | 13,228 |
Concentration of Credit Risk | Concentration of Credit Risk The Company sells its products and services to a significant number of large and small customers throughout the world, with net sales to the pharmaceutical industry of approximately 57%, 59% and 60% in 2023, 2022 and 2021, respectively. None of the Company’s individual customers accounted for more than 2% of annual Company sales in 2023, 2022 or 2021. The Company performs continuing credit evaluations of its customers and generally does not require collateral, but in certain circumstances may require letters of credit or deposits. Historically, the Company has not experienced significant credit losses.
Inventory | Inventory The Company values all of its inventories at the lower of cost or net realizable value on a first-in, first-out basis (“FIFO”).
Income Taxes | Income Taxes As part of the process of preparing the consolidated financial statements, the Company is required to estimate its income taxes in each of the jurisdictions in which it operates. This process involves the Company estimating its income taxes, taking into account the amount, timing and character of taxable income, tax deductions and credits and assessing changes in tax laws, regulations, agreements and treaties. Differing treatment of items for tax and accounting purposes, such as depreciation, amortization and inventory reserves, result in deferred tax assets and liabilities, which are included within the consolidated balance sheets. In the event that actual results differ from these estimates, or the Company adjusts these estimates in future periods, such changes could materially impact the Company’s financial position and results of operations. The accounting standards for income taxes require that a company continually evaluate the necessity of establishing or changing a valuation allowance for deferred tax assets depending on whether it is more likely than not that the actual benefit of those assets will be realized in future periods. The Company accounts for its uncertain tax return positions in accordance with the accounting standards for income taxes, which require financial statement reporting of the expected future tax consequences of uncertain tax positions on the presumption that all concerned tax authorities possess full knowledge of those tax positions, as well as all of the pertinent facts and circumstances, but prohibit any discounting of unrecognized tax benefits associated with those positions for the time value of money. The Company classified interest and penalties related to unrecognized tax benefits as a component of the provision for income taxes.
Leases | Leases The Company’s lease portfolio consists primarily of operating leases. The Company’s operating leases consist of property leases for sales, demonstration, laboratory, warehouse and office spaces, automotive leases for sales and service personnel and equipment leases, primarily used in our manufacturing and distribution operations. The Company categorizes leases as either operating or finance leases at the commencement date of the lease. The Company does not have any material financing leases. The Company makes variable lease payments that do not depend on a rate or index, primarily for items such as real estate taxes and other expenses. These expenses are recorded as variable costs in the period incurred. For the years ended December 31, 2023, 2022 and 2021, variable costs incurred were not material. The Company’s lease agreements may include tenant improvement allowances, rent holidays, and/or contingent rent provisions as well as a certain number of these leases contain rental escalation clauses that are either fixed or adjusted periodically for inflation of market rates which are factored into our determination of lease payments at lease inception. The Company’s leases also sometimes include renewal options and/or termination options which are included in the determination of the lease term when they are reasonably certain to be exercised. The Company has lease agreements which contain lease and non-lease components, which are accounted for as a single lease component for all underlying classes of assets. For leases with terms greater than 12 months, the Company records a right-of-use asset and lease liability at the present value of lease payments over the term of the leases and records rent expense on a straight-line basis over the lease term. The Company has elected not to apply the recognition requirements to short-term leases with terms less than 12 months. For short-term leases, the Company recognizes lease payments in net income on a straight-line basis over the term of the lease. For the years ended December 31, 2023, 2022 and 2021, costs incurred related to short-term leases were not material. When available, the Company uses the rate implicit in the lease to discount lease payments to determine the present value of the lease liabilities; however, most of the leases do not provide a readily determinable implicit rate and, as required by the accounting guidance, the Company estimates its incremental secured borrowing rate to discount the lease payments based on information available at lease commencement (or, for the leases in existence on the adoption date, the January 1, 2019 information). The Company’s incremental borrowing rate reflects the estimated rate of interest that the Company would pay to borrow on a collateralized basis over a similar term to the lease payments in a similar economic environment.
Property, Plant and Equipment | Property, Plant and Equipment Property, plant and equipment are recorded at cost. Expenditures for maintenance and repairs are charged to expense, while the costs of significant improvements are capitalized. Depreciation is provided using the straight-line method over the following estimated useful lives: buildings — fifteen to thirty-nine years; building improvements — five to ten years; leasehold improvements — the shorter of the economic useful life or life of lease; and production and other equipment — three to ten years. Upon retirement or sale, the cost of the assets disposed of and the related accumulated depreciation are eliminated from the consolidated balance sheets and related gains or losses are reflected in the consolidated statements of operations.
Asset Impairments | Asset Impairments The Company reviews its long-lived assets for impairment in accordance with the accounting standards for property, plant and equipment. Whenever events or circumstances indicate that the carrying amount of an asset may not be recoverable, the Company evaluates the recoverability of the carrying value of the asset based on the expected future cash flows, relying on a number of factors, including, but not limited to, operating results, business plans, economic projections and anticipated future cash flows. If the asset is deemed not recoverable, it is written down to fair value and the impairment is recorded in the consolidated statements of operations. During 2022, the Company recorded a total non-cash charge of $6 million in other income (expense), net in the consolidated statement of operations for the impairment of various equity investments without readily determinable fair values accounted for under the measurement alternative or the equity method of accounting. The impairments resulted from the substantial doubt of the investees ability to continue as a going concern.
Business Combinations and Asset Acquisitions | Business Combinations and Asset Acquisitions The Company accounts for business acquisitions under the accounting standards for business combinations. The results of each acquisition are included in the Company’s consolidated results as of the acquisition date and the purchase price of an acquisition is allocated to tangible and intangible assets and assumed liabilities based on their estimated fair values. Any excess of the fair value consideration transferred over the estimated fair values of the net assets acquired is recognized as goodwill. We use assumptions and estimates in determining the fair value of assets acquired and liabilities assumed. The determination of the fair value of intangible assets, which represents a significant portion of the purchase price in our recent acquisition of Wyatt, requires the use of significant judgment with regard to (i) the fair value; and (ii) whether such intangibles are amortizable or non-amortizable and, if the former, the period and the method by which the intangible asset will be amortized. We utilize commonly accepted valuation techniques, such as the income, cost and market approaches, as appropriate, in establishing the fair value of intangible as sets. Typically, key assumptions include projections of cash flows that arise from identifiable intangible assets of acquired businesses as well as discount rates based on an analysis of the weighted average cost of capital, adjusted for specific risks associated with the assets. In our recent acquisition of Wyatt, customer relationship intangible assets have been the most significant identifiable assets acquired. The customer relationships were valued using the multi-period excess earnings method under the income approach. Our cash flow projections for the customer relationships acquired included significant judgments and assumptions related to customer attrition rate, discount rate, and forecasted revenues.
Goodwill and Other Intangible Assets | Goodwill and Other Intangible Assets Goodwill and indefinite-lived intangible assets are not amortized, but are evaluated for impairment on an annual basis, or on an interim basis when events or changes in circumstances indicate that the carrying value may not be recoverable. In assessing the recoverability of goodwill and indefinite-lived intangible assets, we must make assumptions regarding the estimated future cash flows, including forecasted revenue growth and the discount rate to determine the fair value of these assets. If these estimates or their related assumptions change in the future, we may be required to record impairment charges against these assets in the reporting period in which the impairment is determined. We test goodwill for impairment at the reporting unit level, which is the operating segment or one level below an operating segment. We have the option of performing a qualitative assessment to determine whether further impairment testing is necessary before performing the quantitative assessment. If as a result of the qualitative assessment, it is more-likely-than-not that the fair value of a reporting unit is less than its carrying amount, a quantitative impairment test will be required. Otherwise, no further testing will be required. If a quantitative impairment test is performed, we compare the fair values of the applicable reporting units with their aggregate carrying values, including goodwill. Estimating the fair value of the reporting units requires significant judgment by management. If the carrying amount of a reporting unit exceeds the fair value of the reporting unit, an impairment charge is recognized for the amount by which the carrying value amount exceeds the reporting unit’s fair value up to the total amount of goodwill allocated to the reporting unit. The Company performs an annual goodwill impairment assessment for its reporting units as of December 31 each year. The Company has two reporting units: Waters and TA. Goodwill is allocated to the reporting units at the time of acquisition. The Company’s intangible assets include purchased technology; capitalized software; costs associated with acquiring Company patents, trademarks and intellectual properties, such as licenses; and acquired IPR&D. Purchased intangibles are recorded at their fair market values as of the acquisition date and amortized over their estimated useful lives, ranging from one to fifteen years. Other intangibles are amortized over a period ranging from one to ten years. Acquired IPR&D is amortized from the date of completion of the acquired program over its estimated useful life. Goodwill totaled $1.3 billion and $430 million as of December 31, 2023 and 2022, respectively. Net intangible assets and long-lived assets amounted to $629 million and $639 million, as of December 31, 2023, respectively, and $227 million and $582 million as of December 31, 2022, respectively.
Software Development Costs | Software Development Costs The Company capitalizes internal and external software development costs for products offered for sale in accordance with the accounting standards for the costs of software to be sold, leased, or otherwise marketed. Capitalized costs are amortized to cost of sales over the period of economic benefit, which approximates a straight-line basis over the estimated useful lives of the related software products, generally three to ten years. The Company capitalized $ 44 million, $ 46 million and $ 36 million of direct expenses that were related to the development of software in 2023, 2022 and 2021, respectively. Net capitalized software included in intangible assets totaled $ 165 million and $ 148 million at December 31, 2023 and 2022, respectively. See Note 8, Goodwill and Other Intangibles. The Company capitalizes software development costs for internal use. Capitalized internal software development costs are amortized over the period of economic benefit, which approximates a straight-line basis over ten years . Net capitalized internal software included in property, plant and equipment totaled $ 14 million and $ 15 million at December 31, 2023 and 2022, respectively.
Other Investments | Other Investments The Company accounts for its investments that represent less than twenty percent ownership, and for which the Company does not have the ability to exercise significant influence, using the accounting standards for investments in equity securities. Investments for which the Company does not have the ability to exercise significant influence, and for which there is not a readily determinable market value, are accounted for at cost, adjusted for subsequent observable price changes as applicable. The Company periodically evaluates the carrying value of its investments for which the Company does not have the ability to exercise significant influence, and for which there is not a readily determinable fair value and carries them at cost, less impairment, adjusted for subsequent observable price changes. For equity investments in which the Company has the ability to exercise significant influence over operating and financial policies of the investee, the equity method of accounting is used. The Company’s share of net income or losses of equity method investments is included in the consolidated statements of operations and was not material in any period presented. During the year ended 2023, the Company received $1 million in proceeds from, and made no investments in, unaffiliated companies. During the year ended December 31, 2022 the Company received $10 million in proceeds from unaf f iliated companies. During the years ended December 31, 2022 and 2021, the Company made investments of $1 million and $2 million in unaffiliated companies, respectively. In 2022, the Company recorded a realized gain of $7 million in other income (expense), net in the consolidated statement of operations due to the sales of various equity investments as well as incurring $6 million in impairment losses. The Company also recognized an additional $2 million non-cash gain on the cashless exercise of a warrant. In 2021, the Company recorded an unrealized gain of $10 million due to an observable change in the fair value of an existing investment the Company does not have the ability to exercise significant influence over.
Fair Value Measurements | Fair Value Measurements In accordance with the accounting standards for fair value measurements and disclosures, certain of the Company’s assets and liabilities are measured at fair value on a recurring basis as of December 31, 2023 and 2022. Fair values determined by Level 1 inputs utilize observable data, such as quoted prices in active markets. Fair values determined by Level 2 inputs utilize data points other than quoted prices in active markets that are observable either directly or indirectly. Fair values determined by Level 3 inputs utilize unobservable data points for which there is little or no market data, which require the reporting entity to develop its own assumptions. The following table represents the Company’s assets and liabilities measured at fair value on a recurring basis at December 31, 2023 (in thousands):
|  | Total at December 31, 2023 |  |  | Quoted Prices in Active Markets for Identical Assets (Level 1) |  |  | Significant Other Observable Inputs (Level 2) |  |  | Significant Unobservable Inputs (Level 3) |

Fair Value of 401(k) Restoration Plan Assets The 401(k) Restoration Plan is a nonqualified defined contribution plan and the assets were held in registered mutual funds and have been classified as Level 1. The fair values of the assets in the plan are determined through market and observable sources from daily quoted prices on nationally recognized securities exchanges. Fair Value of Cash Equivalents, Investments, Foreign Currency Exchange Contracts, Interest Rate Cross-Currency Swaps Agreements and Interest Rate Swap Cash Flow Hedges The fair values of the Company’s cash equivalents, investments, foreign currency exchange contracts, interest rate cross-currency swap agreements and interest rate swap cash flow hedges are determined through market and observable sources and have been classified as Level 2. These assets and liabilities have been initially valued at the transaction price and subsequently valued, typically utilizing third-party pricing services. The pricing services use many inputs to determine value, including reportable trades, benchmark yields, credit spreads, broker/dealer quotes, current spot rates and other industry and economic events. The Company validates the prices provided by third-party pricing services by reviewing their pricing methods and obtaining market values from other pricing sources. Fair Value of Contingent Consideration The fair value of the Company’s liability for contingent consideration is determined using a probability-weighted discounted cash flow model, which uses significant unobservable inputs, and has been classified as Level 3. Subsequent changes in the fair value of the contingent consideration liability are recorded in the results of operations. Fair Value of Other Financial Instruments The Company’s accounts receivable and accounts payable are recorded at cost, which approximates fair value due to their short-term nature. The carrying value of the Company’s variable interest rate debt approximates fair value due to the variable nature of the interest rate. The carrying value of the Company’s fixed interest rate debt was $1.3 billion at both December 31, 2023 and 2022. The fair value of the Company’s fixed interest rate debt was estimated using discounted cash flow models, based on estimated current rates offered for similar debt under current market conditions for the Company. The fair value of the Company’s fixed interest rate debt was estimated to be $1.2 billion and $1.1 billion at December 31, 2023 and 2022, respectively, using Level 2 inputs.
Derivative Transactions | Derivative Transactions The Company is a global company that operates in over 35 countries and, as a result, the Company’s net sales, cost of sales, operating expenses and balance sheet amounts are significantly impacted by fluctuations in foreign currency exchange rates. The Company is exposed to currency price risk on foreign currency exchange rate fluctuations when it translates its non-U.S. dollar foreign subsidiaries’ financial statements into U.S. dollars and when any of the Company’s subsidiaries purchase or sell products or services in a currency other than its own currency. The Company’s principal strategies in managing exposures to changes in foreign currency exchange rates are to (1) naturally hedge the foreign-currency-denominated liabilities on the Company’s balance sheet against corresponding assets of the same currency, such that any changes in liabilities due to fluctuations in foreign currency exchange rates are typically offset by corresponding changes in assets and (2) mitigate foreign exchange risk exposure of international operations by hedging the variability in the movement of foreign currency exchange rates on a portion of its euro-denominated and yen-denominated net asset investments. The Company presents the derivative transactions in financing activities in the statement of cash flows. Foreign Currency Exchange Contracts The Company does not specifically enter into any derivatives that hedge foreign-currency-denominated operating assets, liabilities or commitments on its balance sheet, other than a portion of certain third-party accounts receivable and accounts payable, and the Company’s net worldwide intercompany receivables and payables, which are eliminated in consolidation. The Company periodically aggregates its net worldwide balances by currency and then enters into foreign currency exchange contracts that mature within 90 days to hedge a portion of the remaining balance to minimize some of the Company’s currency price risk exposure. The foreign currency exchange contracts are not designated for hedge accounting treatment. Principal hedged currencies include the euro, Japanese yen, British pound, Mexican peso and Brazilian real. Cash Flow Hedges The Company’s Credit Facility is a variable borrowing and has interest payments based on a contractually specified interest rate index. The contractually specified index on the Credit Facility is the 3-month Term SOFR. The variable rate interest payments create interest risk for the Company as interest payments will fluctuate based on changes in the contractually specified interest rate index over the life of the Credit Facility. In order to reduce interest rate risk, the Company enters into interest rate swaps that will effectively lock-in the forecasted interest payments on the variable rate borrowing over its term. The interest rate swaps represent cash flow hedges and are assessed for hedge effectiveness each reporting period. When the hedge relationship is highly effective at achieving offsetting changes in cash flows, the Company will record the entire change in fair value of the interest rate swaps in accumulated other comprehensive loss. The amount in accumulated other comprehensive loss is reclassified to earnings in the period that the underlying transaction impacts consolidated earnings. If it becomes probable that the forecasted transaction will not occur, the hedge relationship will be de-designated and amounts accumulated in other comprehensive loss will be reclassified to earnings in the current period. Interest settlements due to benchmark interest rate changes are recorded in interest income or interest expense. For the year ended December 31, 2023, the Company did not have any cash flow hedges that were deemed ineffective. Interest Rate Cross-Currency Swap Agreements As of December 31, 2023, the Company had entered into interest rate cross-currency swap derivative agreements with durations up to three years with an aggregate notional value of $ 625 million to hedge the variability in the movement of foreign currency exchange rates on a portion of its euro-denominated and yen-denominated net asset investments. Under hedge accounting, the change in fair value of the derivative that relates to changes in the foreign currency spot rate are recorded in the currency translation adjustment in other comprehensive income and remain in accumulated other comprehensive loss in stockholders’ equity until the sale or substantial liquidation of the foreign operation. The difference between the interest rate received and paid under the interest rate cross-currency swap derivative agreement is recorded in interest income in the statement of operations. The Company’s foreign currency exchange contracts, interest rate cross-currency swap agreements and interest rate swap agreements designated as cash flow hedges are included in the consolidated balance sheets are classified as follows (in thousands):
|  | December 31, 2023 |  |  | December 31, 2022 |

Cash Flow Hedges | Cash Flow Hedges The Company’s Credit Facility is a variable borrowing and has interest payments based on a contractually specified interest rate index. The contractually specified index on the Credit Facility is the 3-month Term SOFR. The variable rate interest payments create interest risk for the Company as interest payments will fluctuate based on changes in the contractually specified interest rate index over the life of the Credit Facility. In order to reduce interest rate risk, the Company enters into interest rate swaps that will effectively lock-in the forecasted interest payments on the variable rate borrowing over its term. The interest rate swaps represent cash flow hedges and are assessed for hedge effectiveness each reporting period. When the hedge relationship is highly effective at achieving offsetting changes in cash flows, the Company will record the entire change in fair value of the interest rate swaps in accumulated other comprehensive loss. The amount in accumulated other comprehensive loss is reclassified to earnings in the period that the underlying transaction impacts consolidated earnings. If it becomes probable that the forecasted transaction will not occur, the hedge relationship will be de-designated and amounts accumulated in other comprehensive loss will be reclassified to earnings in the current period. Interest settlements due to benchmark interest rate changes are recorded in interest income or interest expense. For the year ended December 31, 2023, the Company did not have any cash flow hedges that were deemed ineffective.
Stockholders' Equity | Stockholders’ Equity In December 2023, the Company’s Board of Directors authorized the extension of the existing share repurchase program through January 21, 2025. The Company’s remaining authorization is $ 1.0 billion. During 2023, 2022 and 2021, the Company repurchased 0.2 million, 2.0 million and 2.0 million shares of the Company’s outstanding common stock at a cost of $58 million, $616 million and $640 million, respectively, under the January 2019 authorization and other previously announced programs. In addition, the Company repurchased $12 million, $11 million and $9 million of common stock related to the vesting of restricted stock units during the years ended December 31, 2023, 2022 and 2021, respectively. As of December 31, 2023, the Company has a total of $1.0 b illion authorized for future repurchases.
Revenue Recognition | Revenue Recognition The Company recognizes revenue upon transfer of control of promised products and services to customers in an amount that reflects the consideration the Company expects to receive in exchange for those products or services. The Company generally enters into contracts that include a combination of products and services. Revenue is allocated to distinct performance obligations and is recognized net of allowances for returns and discounts. The Company recognizes revenue on product sales at the time control of the product transfers to the customer. Certain of the Company’s customers have terms where control of the product transfers to the customer on shipment, while others have terms where control transfers to the customer on delivery. All incremental costs of obtaining a contract are expensed as and when incurred if the expected amortization period of the asset that would have been recognized is one year or less. Shipping and handling costs are included as a component of cost of sales. In situations where the control of the goods transfers prior to the completion of the Company’s obligation to ship the products to its customers, the Company has elected the practical expedient to account for the shipping services as a fulfillment cost. Accordingly, such costs are recognized when control of the related goods is transferred to the customer. In more rare situations, the Company has revenue associated with products that contain specific customer acceptance criteria and the related revenue is not recognized before the customer acceptance criteria are satisfied. The Company elected to exclude from the measurement of the transaction price all taxes assessed by a governmental authority that are both imposed on and concurrent with specific revenue-producing transactions and collected by the Company from a customer. Generally, the Company’s contracts for products include a performance obligation related to installation. The Company has determined that the installation represents a distinct performance obligation and revenue is recognized separately upon the completion of installation. The Company determines the amount of the transaction price to allocate to the installation service based on the standalone selling price of the product and the service, which requires judgment. The Company determines the relative standalone selling price of installation based upon a number of factors, including hourly service billing rates and estimated installation hours. In developing these estimates, the Company considers past history, competition, billing rates of current services and other factors. The Company has sales from standalone software, which are included in product revenue. These arrangements typically include software licenses and maintenance contracts, both of which the Company has determined are distinct performance obligations. The Company determines the amount of the transaction price to allocate to the license and maintenance contract based on the relative standalone selling price of each performance obligation. Software license revenue is recognized at the point in time when control has been transferred to the customer. The revenue allocated to the software maintenance contract is recognized on a straight-line basis over the maintenance period, which is the contractual term of the contract, as a time-based measure of progress best reflects the Company’s performance in satisfying this obligation. Unspecified rights to software upgrades are typically sold as part of the maintenance contract on a when-and-if-available basis. Payment terms and conditions vary among the Company’s revenue streams, although terms generally include a requirement of payment within 30 to 60 days of product shipment. Prior to providing payment terms to customers, an evaluation of their credit risk is performed. Returns and customer credits are infrequent and insignificant and are recorded as a reduction to sales. Rights of return are not included in sales arrangements and, therefore, there is minimal variable consideration included in the transaction price of our products. Service revenue includes (1) service and software maintenance contracts and (2) service calls (time and materials). Instrument service contracts and software maintenance contracts are typically annual contracts, which are billed at the beginning of the contract or maintenance period. The amount of the service and software maintenance contract is recognized on a straight-line basis to revenue over the maintenance service period, which is the contractual term of the contract, as a time-based measure of progress best reflects the Company’s performance in satisfying this obligation. There are no deferred costs associated with the service contract, as the cost of the service is recorded when the service is performed. Service calls are recognized to revenue at the time a service is performed.
Product Warranty Costs | Product Warranty Costs The Company accrues estimated product warranty costs at the time of sale, which are included in cost of sales in the consolidated statements of operations. While the Company engages in extensive product quality programs and processes, including actively monitoring and evaluating the quality of its component suppliers, the Company’s warranty obligation is affected by product failure rates, material usage and service delivery costs incurred in correcting a product failure. The amount of the accrued warranty liability is based on historical information, such as past experience, product failure rates, number of units repaired and estimated costs of material and labor. The liability is reviewed for reasonableness at least quarterly. The following is a summary of the activity of the Company’s accrued warranty liability for the twelve months ended December 31, 2023, 2022 and 2021 (in thousands):
|  | Balance at Beginning of Period |  |  | Accruals for Warranties |  |  | Settlements Made |  |  | Balance at End of Period |
Accrued warranty liability: |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
December 31, 2023 |  | $ | 11,949 |  |  | $ | 7,727 |  |  | $ | (7,626 | ) |  | $ | 12,050 |
December 31, 2022 |  | $ | 10,718 |  |  | $ | 10,067 |  |  | $ | (8,836 | ) |  | $ | 11,949 |
December 31, 2021 |  | $ | 10,950 |  |  | $ | 8,799 |  |  | $ | (9,031 | ) |  | $ | 10,718 |
Advertising Costs | Advertising Costs All advertising costs are expensed as incurred and are included in selling and administrative expenses in the consolidated statements of operations. Advertising expenses were $7 million for the years ended December 31, 2023, 2022 and 2021.
Research and Development Expenses | Research and Development Expenses Research and development expenses are comprised of costs incurred in performing research and development activities, including salaries and benefits, facilities costs, overhead costs, contract services and other outside costs. Research and development expenses are expensed as incurred.
Stock-Based Compensation | Stock-Based Compensation The Company has two stock-based compensation plans, which are described in Note 14, “Stock-Based Compensation”.
Earnings Per Share | Earnings Per Share In accordance with the earnings per share accounting standards, the Company presents two earnings per share (“EPS”) amounts. Income per basic common share is based on income available to common shareholders and the weighted-average number of common shares outstanding during the periods presented. Income per diluted common share includes additional dilution from potential common stock, such as stock issuable pursuant to the exercise of stock options outstanding.
Retirement Plans | Retirement Plans The Company sponsors various retirement plans, which are described in Note 17, “Retirement Plans”.
Comprehensive Income | Comprehensive Income The Company accounts for comprehensive income in accordance with the accounting standards for comprehensive income, which establish the accounting rules for reporting and displaying comprehensive income. These standards require that all components of comprehensive income be reported in a financial statement that is displayed with the same prominence as other financial statements.
Restructuring | Restructuring In July 2023, the Company made organizational changes to better align its resources with its growth and innovation strategies, resulting in a worldwide workforce reduction, that has impacted approximately 5% of the Company’s employees. During 2023, the Company incurred $26 million of severance-related costs in connection with this reduction, which was recorded in selling and administrative expenses in the consolidated statement of operations. During 2023, the Company paid $ 19 million of these costs with the majority of the remaining costs to be paid in the first half of 2024.
New Accounting Pronouncements | Recently Adopted Accounting Standards In October 2021, accounting guidance was issued that requires acquirers in a business combination to recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Topic 606. The new guidance requires that at the acquisition date, the acquirer should account for the related revenue contracts in accordance with 606 as if it had originated the contracts. This guidance differs from current GAAP which requires an acquirer to recognize assets acquired and liabilities assumed in a business combination, including contract assets and contract liabilities arising from revenue contracts with customers and other similar contracts that are accounted for in accordance with 606, at fair value on the acquisition date. This guidance is effective for public business entities for fiscal years beginning after December 15, 2022, including interim periods within those years. The Company adopted this standard on January 1, 2023. The adoption of this standard did not have a material impact on the Company’s financial position, results of operations and cash flows. Recently Issued Accounting Standards In March 2020, accounting guidance was issued that facilitates the effects of reference rate reform on financial reporting. The amendments in the update provide optional guidance for a limited period of time to ease the potential burden in accounting for or recognizing the effects of reference rate reform on financial reporting and apply to all entities, subject to meeting certain criteria, that have contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. In January of 2021, an update was issued to clarify that certain optional expedients and exceptions under the reference rate reform guidance for contract modifications and hedge accounting apply to derivatives that are affected by the discounting transition. Specifically, certain provisions in the reference rate reform guidance, if elected by an entity, apply to derivative instruments that use an interest rate for margining, discounting, or contract price alignment that is modified as a result of reference rate reform. This temporary guidance is effective for all entities as of March 12, 2020, through December 31, 2022. In December 2022, an update was issued because the cessation date for overnight LIBOR rates being published was extended to June 30, 2023, which was beyond the current expiration date of this guidance. The update extended the sunset date to December 31, 2024. The Company may elect to apply this guidance for all contract modifications or eligible hedging relationships during that time period subject to certain criteria. The Company does not believe that it has material reference rate exposure which would require utilizing the guidance under this accounting pronouncement and if adopted does not believe that this standard would have a material impact on the Company’s financial position, results of operations and cash flows. In November 2023, accounting guidance was issued that requires additional disclosures of reportable segment information. The guidance requires that public entities disclose, on an annual and interim basis (1) significant segment expenses that are regularly provided to the chief operating decision maker (“CODM”) and included within each reported measure of segment profit or loss, (2) an amount for other segment items by reportable segment and a description of its composition (the other segment items category is the difference between segment revenue less the segment expenses disclosed under the significant expense principle and each reported measure of segment profit or loss), (3) provide all annual disclosures about a reportable segment’s profit or loss and assets currently required by Topic 280 in interim periods, (4) clarify that if the CODM uses more than one measure of a segment’s profit or loss in assessing segment performance and deciding how to allocate resources, a public entity may report one or more of those additional measures of segment profit. However, at least one of the reported segment profit or loss measures (or the single reported measure, if only one is disclosed) should be the measure that is most consistent with the measurement principles used in measuring the corresponding amounts in the public entity’s consolidated financial statements, (5) the title and position of the CODM and an explanation of how the CODM uses the reported measure(s) of segment profit or loss in assessing segment performance and deciding how to allocate resources, and (6) if a public entity has a single reportable segment to provide all the disclosures required by the amendments in this update and all existing segment disclosures in Topic 280. The amendments in this update do not change how operating segments are identified or aggregated nor how the quantitative thresholds are applied to determine its reportable segments. The amendments in this update are effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. The amendments in this update should be applied retrospectively to all prior periods presented in the financial statements. Upon transition, the segment expense categories and amounts disclosed in the prior periods should be based on the significant segment expense categories identified and disclosed in the period of adoption. The Company does not believe this accounting standard update will have material impact on the Company’s financial position, results of operations and cash flows. The Company is currently evaluating the impact the adoption of this accounting standard update will have on our footnote disclosures. In December 2023, accounting guidance was issued to enhance the transparency and decision usefulness of income tax disclosures. The amendments in this update change disclosure requirements related to the rate reconciliation, income taxes paid and other disclosures. For the rate reconciliation the amendments require that public business entities on an annual basis (1) disclose specific categories in the rate reconciliation and (2) provide additional information for reconciling items that meet a quantitative threshold. For income taxes paid the amendments require that all entities disclose on an annual basis the following information; (1) the amount of income taxes paid (net of refunds received) disaggregated by federal (national), state, and foreign taxes, (2) the amount of income taxes paid (net of refunds received) disaggregated by individual jurisdictions in which income taxes paid (net of refunds received) is equal to or greater than 5 percent of total income taxes paid (net of refunds received). Finally, for other disclosures the amendments require that all entities disclose the following information: (1) income (or loss) from continuing operations before income tax expense (or benefit) disaggregated between domestic and foreign, and (2) income tax expense (or benefit) from continuing operations disaggregated by federal (national), state, and foreign. This update also eliminates the requirement for all entities to (1) disclose the nature and estimate of the range of the reasonably possible change in the unrecognized tax benefits balance in the next 12 months or (2) make a statement that an estimate of the range cannot be made. As well as removing the requirement to disclose the cumulative amount of each type of temporary difference when a deferred tax liability is not recognized because of the exceptions to comprehensive recognition of deferred taxes related to subsidiaries and corporate joint ventures. The amendments in this update are effective for annual periods beginning after December 15, 2024. Early adoption is permitted for annual financial statements that have not yet been issued or made available for issuance. The amendments in this update should be applied on a prospective basis and retrospective application is permitted. The Company does not believe this accounting standard update will have material impact on the Company’s financial position, results of operations and cash flows. The Company is currently evaluating the impact the adoption of this accounting standard update will have on our footnote disclosures.
