Accounting Policies [Abstract]  
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Basis of Presentation 
The Company's Consolidated Financial Statements include the accounts of the Company and its wholly-owned subsidiaries, including acquired businesses from the dates of acquisition. All intercompany accounts and transactions have been eliminated in consolidation.

Use of Estimates
The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America ("U.S. GAAP") requires management to make estimates and assumptions that affect the amounts reported in the financial statements and footnotes thereto. Actual results may differ significantly from those estimates. The estimates underlying the Company's Consolidated Financial Statements relate to, among other things, the valuation of goodwill and other long-lived tangible and intangible assets, the valuation of investments in private companies, income taxes, contingencies, stock-based compensation, the allowance for expected credit losses (also referred to as provision for bad debts or provision for uncollectible accounts), chargeback provisions, and the accrual of obligations for loyalty and other incentive programs.

Impact of COVID-19
The Company's financial results and prospects are almost entirely dependent on facilitating the sale of travel-related services. The COVID-19 pandemic and the resulting implementation of travel restrictions by governments around the world resulted in a significant decline in travel activities and consumer demand for travel related services, in 2020 in particular. During the year ended December 31, 2020, given the severe downturn in the global travel industry and the financial difficulties faced by many of the Company's travel service provider and restaurant customers and marketing affiliates, the Company increased its provision for expected credit losses (also referred to as provision for bad debts or provision for uncollectible accounts) on receivables from and prepayments to its travel service provider and restaurant customers and marketing affiliates (see Note 7). Moreover, due to the high level of cancellations of existing reservations, the Company incurred higher than normal cash outlays to refund consumers for prepaid reservations, including certain situations where the Company had already transferred the prepayment to the travel service provider. During the year ended December 31, 2021, based on its review of recent historical credit loss experience and stability in the economic conditions in certain markets, the Company revised its estimates of expected credit losses (see Note 7). Any significant increase in the Company’s provision for expected credit losses and any significant increase in cash outlays to refund consumers would have a corresponding adverse effect on the Company's results of operations and related cash flows.

As a result of the deterioration of the Company’s business due to the COVID-19 pandemic, the Company recorded significant goodwill impairment charges during the year ended December 31, 2020 (see Note 11). In addition, the Company recorded a significant impairment charge during the year ended December 31, 2020 for one of the Company's long-term investments (see Notes 5 and 6). It is possible that the Company may have to record additional significant impairment charges in future periods.
In response to the reduction in the Company's business volumes as a result of the impact of the COVID-19 pandemic, during the year ended December 31, 2020, the Company took actions to reduce the size of its workforce to optimize efficiency and reduce costs. See Note 19 for additional information. The Company also participated in certain governmental assistance programs and received certain grants and other assistance. In June 2021, the Company announced its intention to voluntarily return the government assistance received and completed the repayments by December 2021. The Company repaid $107 million during the year ended December 31, 2021. See Note 20 for additional information.

Even though there have been improvements in the economic and operating conditions for the Company's business since the outset of the COVID-19 pandemic, the Company cannot predict the long-term effects of the pandemic on its business or the travel and restaurant industries as a whole.

Reclassification
Certain amounts from prior periods have been reclassified to conform to the current year presentation.

Fair Value of Financial Instruments
Certain financial instruments, including cash, restricted cash, accounts payable, accrued expenses, and deferred merchant bookings, are carried at cost which approximates their fair value because of the short-term nature of these financial instruments. Accounts receivable and other financial assets measured at amortized cost are carried at cost less an allowance for expected credit losses to present the net amount expected to be collected (see Note 7). See Notes 5, 6, and 12 for information related to fair value for investments, derivatives, and the Company's outstanding senior notes.

There are three levels of inputs to valuation techniques used to measure fair value:
Level 1:    Quoted prices in active markets that are accessible by the Company at the measurement date for identical assets and liabilities.
Level 2:    Inputs that are observable, either directly or indirectly. Such prices may be based upon quoted prices for identical or comparable securities in active markets or inputs not quoted on active markets, but corroborated by market data.
Level 3:    Unobservable inputs are used when little or no market data is available.
 
Cash and Cash Equivalents
Cash and cash equivalents consists primarily of cash and highly liquid investment grade securities with an original maturity of three months or less. Cash equivalents are recognized based on settlement date.
 
Restricted Cash and Cash Equivalents
Restricted cash and cash equivalents are restricted through legal contracts or regulations. Restricted cash and cash equivalents at December 31, 2022 and 2021 principally relate to the minimum cash requirement for the Company's travel-related insurance business.

The following table reconciles cash and cash equivalents and restricted cash and cash equivalents reported in the Consolidated Balance Sheets to the total amount shown in the Consolidated Statements of Cash Flows (in millions):

Investments
Investments held by the Company include debt securities and equity securities. Investments in debt or equity securities that include embedded features, such as conversion or redemption features, are analyzed by the Company to determine if these features are embedded derivatives that require separate accounting treatment. Payments made for investments are reported in "Purchase of investments" and proceeds received from sales or maturities of investments are reported in "Proceeds from sale and maturity of investments" in the Consolidated Statements of Cash Flows.

Debt Securities
The Company has classified its investments in debt securities as available-for-sale securities. Preferred stock that is either mandatorily redeemable or redeemable at the option of the investor is considered a debt security for accounting purposes. These securities are reported at estimated fair value with the aggregate unrealized gains and losses, net of tax, reflected in "Accumulated other comprehensive loss" in the Consolidated Balance Sheets. The fair value of these investments is based on the specific quoted market price of the securities or comparable securities at the balance sheet dates. Unobservable inputs are also used when little or no market data is available. See Note 6 for information related to fair value measurements.

If the amortized cost basis of an available-for-sale security exceeds its fair value and if the Company has the intention to sell the security or it is more likely than not that the Company will be required to sell the security before recovery of the amortized cost basis, an impairment is recognized in the Consolidated Statements of Operations. If the Company does not have the intention to sell the security and it is not more likely than not that the Company will be required to sell the security before recovery of the amortized cost basis and the Company determines that the decline in fair value below the amortized cost basis of an available-for-sale security is entirely or partially due to credit-related factors, the credit loss is measured and recognized as an allowance for expected credit losses along with the related expense in the Consolidated Statements of Operations. The allowance is measured as the amount by which the debt security’s amortized cost basis exceeds the Company’s best estimate of the present value of cash flows expected to be collected.

The Company's investments in marketable debt securities are recognized based on the trade date. The cost of marketable debt securities sold is determined using a first-in and first-out method. The Company's investments in debt securities are assessed for classification in the Consolidated Balance Sheets as short-term or long-term at the individual security level. Classification as short-term or long-term is based on the maturities of the securities, as applicable, and the Company's expectations regarding the timing of sales and redemptions. Investments of a strategic nature that have been made for the purpose of affiliation or potential business advantage or in connection with a commercial relationship are included in "Long-term investments" in the Consolidated Balance Sheets, except in situations where the Company expects the investment to be realized in cash, redeemed, or sold within one year.

Equity Securities
Equity securities are reported as "Long-term investments" in the Consolidated Balance Sheets and include equity investments with readily determinable fair values and equity investments without readily determinable fair values. Equity investments with readily determinable fair values are reported at estimated fair value with changes in fair value recognized in "Other income (expense), net" in the Consolidated Statements of Operations.

The Company holds investments in equity securities of private companies, over which the Company does not have the ability to exercise significant influence or control. These investments, which do not have readily determinable fair values, are measured at cost less impairment, if any. Such investments are also required to be measured at fair value as of the date of certain observable transactions for the identical or a similar investment of the same issuer.

Accounts Receivable from Customers and Allowance for Expected Credit Losses
Accounts receivable is reported net of expected credit losses. The Company estimates lifetime expected credit losses upon recognition of the financial assets. The Company has identified the relevant risk characteristics of its customers and the related receivables and prepayments, which include the following: size, type (alternative accommodations vs. hotels) or geographic location of the customer, or a combination of these characteristics. Receivables with similar risk characteristics have been grouped into pools. For each pool, the Company considers the historical credit loss experience, current economic conditions, supportable forecasts of future economic conditions, and any recoveries in assessing the lifetime expected credit losses. Other key factors that influence the expected credit loss analysis include customer demographics, payment terms offered in the normal course of business to customers, the nature of competition, and industry-specific factors that could impact the Company's receivables. Additionally, external data and macroeconomic conditions are considered. This is assessed at each quarter based on the Company’s specific facts and circumstances.
Property and Equipment, Net
Property and equipment are stated at cost less accumulated depreciation. Depreciation is computed on a straight-line basis over the estimated useful lives of the assets or, when applicable, the term of the lease related to leasehold improvements, whichever is shorter.

Website and Internal-use Software Capitalization
Acquisition costs and certain direct development costs associated with website and internal-use software are capitalized and include external direct costs of services and payroll costs for employees devoting time to the software projects principally related to platform development, including support systems, software coding, designing system interfaces, and installation and testing of the software. These costs are recorded as property and equipment and are generally amortized beginning when the asset is substantially ready for use. Costs incurred for enhancements that are expected to result in additional features or functionalities are capitalized and amortized over the estimated useful life of the enhancements. Costs incurred during the preliminary project stage, as well as maintenance and training costs, are expensed as incurred.

Cloud Computing Arrangements
The Company utilizes various third-party computer systems and third-party service providers, including global distribution systems ("GDSs") and computerized central reservation systems of the accommodation, rental car, and airline industries in connection with providing some of its services. The Company uses both internally-developed systems and third-party systems to operate its services, including transaction processing, order management, and financial and accounting systems. Implementation costs incurred in a hosting arrangement that is a service contract are capitalized and amortized over the term of the hosting arrangement. The capitalized implementation costs are reported as "Prepaid expenses, net" or "Other assets, net" in the Company's Consolidated Balance Sheets, as appropriate. The related amortization expenses are reported as "Information technology" in the Company's Consolidated Statements of Operations.

Leases
The Company determines if an arrangement is a lease, or contains a lease, when a contract is signed. The Company determines if a lease is an operating or finance lease and records a lease asset and a lease liability upon lease commencement, which is the date when the underlying asset is made available for use by the lessor. The Company has operating leases for office space, and data centers. For office space and data centers, the Company has elected to combine the fixed payments to lease the asset and any fixed non-lease payments (such as maintenance or utility charges) when determining its lease payments. The Company's finance leases are mainly for computer equipment.

The Company uses its incremental borrowing rate as its discount rate to determine the present value of its remaining lease payments to calculate its lease assets and lease liabilities because the rate implicit in the lease is not readily determinable. The incremental borrowing rate approximates the rate the Company would pay to borrow in the currency of the lease payments on a collateralized basis for the weighted-average life of the lease. Operating lease assets also include any prepaid lease payments and lease incentives received prior to lease commencement.

The Company recognizes operating lease costs and the amortization of finance lease assets on a straight-line basis over the lease term. The interest component of a finance lease is recognized using the effective interest method over the lease term. Certain of the Company's lease agreements include rent payments which are adjusted periodically based on an index or rate. Any change in payments due to such adjustments are recognized as variable lease expense as they are incurred. Variable lease expense also includes costs for property taxes, insurance, and services provided by the lessor which are charged based on usage or performance (such as maintenance or utility charges).

Most leases have one or more options to renew beyond their initial term. The exercise of renewal options, mainly for office space and data centers, is at the Company’s discretion and are included in the determination of the lease term for accounting purposes if they are reasonably certain to be exercised.

Business Combinations, Goodwill, and Intangible Assets
The Company accounts for acquired businesses using the acquisition method of accounting. The consideration transferred is allocated to the assets acquired and liabilities assumed based on their respective values at the acquisition date. The excess of the consideration transferred over the net of the amounts allocated to the identifiable assets acquired and liabilities assumed is recognized as goodwill.
In 2021, the Financial Accounting Standards Board ("FASB") issued a new accounting standards update that requires an acquirer to recognize and measure contract assets and contract liabilities in a business combination in accordance with ASC 606, Revenue from Contracts with Customers, rather than at fair value on the acquisition date as required under legacy U.S. GAAP. The Company adopted this update in 2021 and applied it to all business combinations occurring on or after January 1, 2021.

Goodwill is assigned to reporting units that are expected to benefit from the synergies of the business combination. Goodwill is not subject to amortization and is tested for impairment on an annual basis and between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. The Company tests goodwill at a reporting unit level. The fair value of the reporting unit is compared to its carrying value, including goodwill. Fair values are determined using a combination of standard valuation techniques, including an income approach (discounted cash flows) and market approaches (e.g., earnings before interest, taxes, depreciation, and amortization ("EBITDA") multiples of comparable publicly traded companies) and based on market participant assumptions. A goodwill impairment loss is measured at the amount by which a reporting unit’s carrying amount exceeds its fair value, not to exceed the carrying amount of goodwill. See Note 11 for additional information.

Intangible assets are carried at cost and amortized on a straight-line basis over their estimated useful lives.

Impairment of Long-lived Assets
The Company reviews long-lived assets, including intangible assets and operating lease assets, whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. The assessment of possible impairment is based upon the Company's ability to recover the carrying value of the assets from the estimated undiscounted future net cash flows, before interest and taxes, of the related asset group. The amount of impairment loss, if any, is measured as the excess of the carrying value of the asset over the present value of estimated future cash flows, using a discount rate commensurate with the risks involved and based on assumptions representative of market participants.

Foreign Currency Translation
The functional currency of the Company's subsidiaries is generally the respective local currency. For operations outside of the U.S., assets and liabilities are translated into U.S. Dollars at the rate of exchange existing at the balance sheet date. Income statement amounts are translated at monthly average exchange rates applicable for the period. Translation gains and losses are included as a component of "Accumulated other comprehensive loss" in the Company's Consolidated Balance Sheets. Foreign currency transaction gains and losses are included in "Other income (expense), net" in the Company's Consolidated Statements of Operations.

Derivatives
Derivatives not Designated as Hedges
As a result of the Company's operations outside of the U.S., it is exposed to various market risks that may affect its consolidated results of operations, cash flows, and financial position. These market risks include, but are not limited to, fluctuations in foreign currency exchange rates. For the Company's operations outside of the U.S., the primary foreign currency exposures are in Euros and British Pounds Sterling, the currencies in which the Company conducts a significant portion of its business activities. As a result, the Company faces exposure to adverse movements in foreign currency exchange rates as the financial results of its operations outside of the U.S. are translated from local currencies into U.S. Dollars upon consolidation. Additionally, foreign currency exchange rate fluctuations on transactions denominated in currencies other than the functional currency of an entity result in gains and losses that are reflected in net income.
 
The Company may enter into derivative instruments to hedge certain net exposures of nonfunctional currency denominated assets and liabilities and the volatility associated with translating earnings for its operations outside of the U.S. into U.S. Dollars, even though it does not elect to apply hedge accounting or hedge accounting does not apply. These contracts are generally short-term in duration. Certain of the Company's derivative instruments have master netting arrangements, which reduce credit risk by permitting net settlement of transactions with the same counterparty. The Company is exposed to the risk that counterparties to derivative instruments may fail to meet their contractual obligations. The Company regularly reviews its credit exposure and assesses the creditworthiness of its counterparties. The Company reports the fair value of its derivative assets and liabilities on a gross basis in the Consolidated Balance Sheets in "Other current assets" and "Accrued expenses and other current liabilities," respectively. Unless designated as hedges for accounting purposes, gains and losses resulting from changes in the fair value of derivative instruments are recognized in "Other income (expense), net" in the Consolidated Statements of Operations in the period that the changes occur and are classified within "Net cash provided by operating
activities" or "Net cash (used in) provided by financing activities," as appropriate, in the Consolidated Statements of Cash Flows. See Note 6 for additional information related to these derivative instruments.

Derivatives Designated as Cash Flow Hedges
See Note 6 for information related to derivatives designated as cash flow hedges.

Non-derivative Instrument Designated as Net Investment Hedge
The foreign currency transaction gains or losses on the Company's Euro-denominated debt are measured based upon changes in spot rates. The foreign currency transaction gains or losses on the Euro-denominated debt that is designated as a hedging instrument for accounting purposes are recorded in "Accumulated other comprehensive loss" in the Consolidated Balance Sheets. The foreign currency transaction gains or losses on the Euro-denominated debt that is not designated as a hedging instrument are recognized in "Other income (expense), net" in the Consolidated Statements of Operations. See Notes 12 and 14 for additional information related to the net investment hedge.

Revenue Recognition
Online travel reservation services
Substantially all of the Company's revenues are generated by providing online travel reservation services, which principally allows travelers to book travel reservations with travel service providers through the Company’s platforms. While the Company generally refers to a consumer that books travel reservation services on the Company's platforms as its customer, for accounting purposes, the Company's customers are the travel service providers and, in certain merchant transactions, the travelers. The Company's contracts with travel service providers give them the ability to market their reservation availability without transferring responsibility to deliver the travel service to the Company. Therefore, the Company's revenues are presented on a net basis in the Consolidated Statements of Operations. These contracts include payment terms and establish the consideration to which the Company is entitled, which includes either a commission or a margin on the travel transaction. Revenue is measured based on the expected consideration specified in the contract with the travel service provider, considering the effects of factors such as discounts and other sales incentives. Estimates for sales incentives are based on historical experience, current trends, and forecasts, as applicable. Coupons are recorded as a reduction of the transaction price, generally at the time they are redeemed. The local occupancy taxes, general excise taxes, value-added taxes, sales taxes, and other similar taxes ("travel transaction taxes"), if any, collected from travelers are reported on a net basis in revenues in the Consolidated Statements of Operations.

Revenues for online travel reservation services are recognized at a point in time when the Company has completed its post-booking services and the travelers begin using the arranged travel services. These services are classified into two categories:

Agency revenues are derived from travel-related transactions where the Company does not facilitate payments from travelers for the services provided. The Company invoices the travel service providers for its commissions in the month that travel is completed. Agency revenues consist almost entirely of travel reservation commissions from the Company's accommodation, rental car, and airline reservation services.

Merchant revenues are derived from travel-related transactions where the Company facilitates payments from travelers for the services provided, generally at the time of booking. Merchant revenues are derived from transactions where travelers book accommodation, rental car, airline reservations, and other travel related services. Merchant revenues include travel reservation commissions and transaction net revenues (i.e., the amount charged to travelers less the amount owed to travel service providers) in connection with the Company's merchant reservations services; credit card processing rebates and customer processing fees; and ancillary fees, including travel-related insurance revenues.

Advertising and Other Revenues
Advertising and other revenues are primarily recognized by KAYAK and OpenTable. KAYAK recognizes advertising revenue primarily by sending referrals to online travel companies ("OTCs") and travel service providers and from advertising placements on its platforms. Revenue related to referrals is recognized when a consumer clicks on a referral placement or upon completion of the travel. Revenue for advertising placements is recognized based upon when a consumer clicks on an advertisement or when KAYAK displays an advertisement. OpenTable recognizes revenues for reservation fees when diners are seated through its online restaurant reservation service and subscription fees for restaurant management services on a straight-line basis over the contractual period in accordance with how the service is provided.
Incentives and Loyalty Programs
The Company provides various incentive programs such as referral bonuses, rebates, credits, and discounts. In addition, the Company offers loyalty programs where participating consumers may be awarded loyalty points on current transactions that can be redeemed in the future. The estimated value of the incentives granted and the loyalty points expected to be redeemed is generally recognized as a reduction of revenue at the time they are granted.

Deferred Merchant Bookings
Cash payments received from travelers in advance of the Company completing its performance obligations are included in "Deferred merchant bookings" in the Company's Consolidated Balance Sheets and are comprised principally of amounts estimated to be payable to travel service providers as well as the Company's estimated future revenue for its commission or margin and fees. The amounts are mostly subject to refunds for cancellations. The Company expects to complete its performance obligations generally within one year from the reservation date. The increase in the Deferred Merchant Booking balance during the year ended December 31, 2022 was principally due to the increase in business volumes.

Marketing Expenses
The Company's advertising expenses are reported in "Marketing expenses" in the Consolidated Statements of Operations. Marketing expenses consist of performance marketing expenses and brand marketing expenses. Performance marketing expenses are expenses generally measured by return on investment or an increase in bookings over a specified time period. These expenses consist primarily of the costs of: (1) search engine keyword purchases; (2) referrals from meta-search and travel research websites; (3) affiliate programs; (4) offline and online brand marketing; and (5) other performance-based marketing and incentives. Performance marketing expenses are recognized as incurred. Included in "Accrued expenses and other current liabilities" in the Consolidated Balance Sheets are accrued liabilities of $480 million and $306 million at December 31, 2022 and 2021, respectively, related to performance marketing. Brand marketing expenses are expenses incurred to build brand awareness over a specified time period. These expenses consist primarily of television advertising and online video and display advertising (including the airing of the Company's television advertising online), as well as other marketing expenses such as public relations and sponsorships. Brand marketing expenses are generally recognized as incurred with the exception of advertising production costs, which are deferred and expensed the first time the advertisement is displayed or broadcast.

Sales and Other Expenses
Sales and other expenses are generally variable in nature and consist primarily of: (1) credit cards and other payment processing fees associated with merchant transactions; (2) fees paid to third parties that provide call center, website content translations, and other services; (3) chargeback provisions and fraud prevention expenses associated with merchant transactions; (4) customer relations costs; and (5) provisions for expected credit losses, primarily related to accommodation commission receivables and prepayments to certain customers.

Personnel
Personnel expenses consist of compensation to the Company's personnel, including salaries, stock-based compensation, bonuses, payroll taxes and employee health and other benefits. Included in "Accrued expenses and other current liabilities" in the Consolidated Balance Sheets are accrued liabilities of $518 million and $421 million at December 31, 2022 and 2021, respectively, related to personnel expenses.
 
Stock-Based Compensation
Stock-based compensation expense related to performance share units, restricted stock units and stock options is recognized based on fair value on a straight-line basis over the respective requisite service periods and forfeitures are accounted for when they occur. The fair value on the grant date of performance share units and restricted stock units is determined based on the number of units granted and the quoted price of the Company's common stock. For performance share units with market conditions, the effect of the market condition is also considered in the determination of fair value on the grant date using Monte Carlo simulations. The fair value of employee stock options is determined using the Black-Scholes model.

The Company records stock-based compensation expense for performance-based awards using its estimate of the probable outcome at the end of the performance period (i.e., the estimated performance against the performance targets or performance goals, as applicable). The Company periodically adjusts the cumulative stock-based compensation expense recorded when the probable outcome for these performance-based awards is updated based upon changes in actual and forecasted operating results or expected achievement of performance goals, as applicable.
 
The benefits of tax deductions in excess of recognized compensation costs are recognized in the Consolidated Statements of Operations as a discrete item when an option exercise or a vesting and release of shares occurs. Excess tax benefits are presented as operating cash flows and cash payments for employee statutory tax withholding related to vested stock awards are presented as financing cash flows in the Consolidated Statements of Cash Flows. 

Benefit Plans
The Company maintains a defined contribution 401(k) savings plan covering certain U.S. employees. The Company also maintains certain other defined contribution plans outside of the United States for which it provides contributions for participating employees. The Company's matching contributions during the years ended December 31, 2022, 2021, and 2020 were $40 million, $32 million, and $33 million, respectively.

Government Grants and Other Assistance
The Company recognizes government grants in the financial statements when it is probable that the grant will be received and the Company will comply with the conditions of the grant. Government grants are recorded as a reduction in the related operating expense or the cost of the asset that they are intended to defray. The government grants received by the Company have principally been granted to defray personnel costs. See Note 20 for information related to government grants and other assistance.

Information Technology 
Information technology expenses consist primarily of: (1) software license and system maintenance fees; (2) outsourced data center and cloud computing costs; (3) payments to contractors; and (4) data communications and other expenses associated with operating the Company's services.

Restructuring, Disposal and Other Exit Activities
The Company records employee severance and other termination costs that meet the requirements for recognition in accordance with the relevant guidance of ASC 420, Exit or Disposal Cost Obligations, or ASC 712, Compensation - Nonretirement Postemployment Benefits, as applicable. For involuntary termination benefits that are not provided under the terms of an ongoing benefit arrangement, the liability for the current fair value of expected future costs associated with a management-approved restructuring plan is recognized in the period in which the plan is communicated to the employees and the plan is not expected to change significantly. For ongoing benefit arrangements, inclusive of statutory requirements, employee termination costs are accrued when the existing situation or set of circumstances indicates that an obligation has been incurred, it is probable the benefits will be paid, and the amount can be reasonably estimated. Termination benefits associated with voluntary leaver schemes are recorded when the employee irrevocably accepts the offer and the amount can be reasonably estimated.

Long-lived assets to be sold are classified as held for sale in the period in which the requirements for such classification are met in accordance with ASC 360, Property, Plant, and Equipment. Assets that are classified as held for sale are measured at the lower of their carrying amount or fair value less cost to sell.

Income Taxes 
The Company accounts for income taxes under the asset and liability method. The Company records the estimated future tax effects of temporary differences between the tax bases of assets and liabilities and amounts reported in the Consolidated Balance Sheets, as well as operating loss and tax credit carryforwards. Deferred taxes are classified as non-current in the Consolidated Balance Sheets.
 
The Company records deferred tax assets to the extent it believes these assets will more likely than not be realized. The Company regularly reviews its deferred tax assets for recoverability considering historical profitability, projected future taxable income, the expected timing of the reversals of existing temporary differences, the carryforward periods available for tax reporting purposes, and tax planning strategies. A valuation allowance is provided when it is more likely than not that some portion or all of a deferred tax asset will not be realized. The ultimate realization of deferred tax assets depends on the generation of future taxable income during the period in which related temporary differences become deductible. In determining the future tax consequences of events that have been recognized in the financial statements or tax returns, significant judgments, estimates, and interpretation of statutes are required.
Deferred taxes are measured using the enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred taxes of a change in tax rates is recognized in income in the period that includes the enactment date of such change.
 
The Company recognizes liabilities when it believes that uncertain positions may not be fully sustained upon audit by the tax authorities. Liabilities recognized for uncertain tax positions are based on a two-step approach for recognition and measurement. First, the Company evaluates the tax position for recognition by determining if the weight of available evidence indicates it is more likely than not that the position will be sustained on audit based on its technical merits. Second, the Company measures the tax benefit as the largest amount that is more than 50% likely of being realized upon ultimate settlement. Interest and penalties attributable to uncertain tax positions, if any, are recognized as a component of income tax expense. 

The Company accounts for taxes on global intangible low-taxed income ("GILTI") introduced by the U.S. Tax Cuts and Jobs Act (the "Tax Act") as period costs. See Note 15 for further details related to income taxes.

Contingencies
Loss contingencies (other than income tax-related contingencies) arise from actual or possible claims and assessments and pending or threatened litigation that may be brought against the Company by individuals, governments or other entities. Based on the Company's assessment of loss contingencies at each balance sheet date, a loss is recorded in the financial statements if it is probable that an asset has been impaired or a liability has been incurred and the amount of the loss can be reasonably estimated.

Recent Accounting Pronouncements Adopted
    
Accounting for Convertible Instruments and Contracts in an Entity's Own Equity
On January 1, 2022, the Company adopted the new accounting standards update relating to convertible instruments and contracts in an entity's own equity. Compared to legacy U.S. GAAP, the accounting standards update reduces the number of accounting models for convertible debt instruments, requires fewer embedded conversion features to be separately recognized from the host contract, and amends certain guidance to reduce form-over-substance-based accounting conclusions. Under the updated guidance, upon the initial recognition of convertible debt, the Company presents the entire amount attributable to the debt as a liability. The initial carrying amount of the convertible debt liability is reduced by any direct and incremental issuance costs paid to third parties that are associated with the convertible debt issuance. No amount attributable to the debt is initially recognized within equity unless the instrument is issued at a substantial premium. In calculating diluted earnings per share, the accounting standards update also requires the use of the if-converted method for the Company's convertible debt.

The Company adopted the accounting standards update on a modified retrospective basis applied to the 0.75% convertible senior notes due May 2025 (see Note 12) resulting in an increase of $30 million to "Retained earnings" as of January 1, 2022. The significant corresponding balance sheet changes as of that date were an increase of $86 million to "Long-term debt" and decreases of $96 million to "Additional paid-in capital" and $21 million to "Deferred income taxes." For the Company’s convertible debt, interest expense for the periods beginning on January 1, 2022 is reflected in the financial statements using interest rates that are closer to the coupon interest rate of the debt rather than the higher imputed interest expense that resulted from the separation of conversion features required by legacy U.S. GAAP. See Note 8 for additional information on net income per share calculations.

Other Recent Accounting Pronouncements

Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions
In June 2022, the FASB issued an accounting standards update with guidance on the fair value measurement of equity securities subject to contractual sale restrictions. The update clarifies that a contractual restriction on the sale of an equity security is not considered part of the unit of account of the equity security and, therefore, is not considered in measuring fair value. The update also clarifies that an entity cannot, as a separate unit of account, recognize and measure a contractual sale restriction. The update also requires certain additional disclosures for equity securities subject to contractual sale restrictions. The amendments in this update are effective for the Company beginning January 1, 2024 on a prospective basis. Early adoption is permitted for both interim and annual financial statements that have not yet been issued or made available for issuance. The Company does not expect the adoption of the accounting standards update to have a material impact on its Consolidated Financial Statements.
