Accounting Policies [Abstract]  
Business Description and Summary of Significant Accounting Policies
The terms “Cognizant,” “we,” “our,” “us” and “the Company” refer to Cognizant Technology Solutions Corporation and its subsidiaries unless the context indicates otherwise.

Digital services continue to be an important part of our portfolio, aligning with our clients' focus on becoming data-enabled, customer-centric and differentiated businesses.
Basis of Presentation, Principles of Consolidation and Use of Estimates. The consolidated financial statements are presented in accordance with GAAP and reflect the consolidated financial position, results of operations, comprehensive income and cash flows of our consolidated subsidiaries for all periods presented. All intercompany balances and transactions have been eliminated in consolidation.

The preparation of financial statements requires management to make estimates and assumptions that affect the reported amounts in the consolidated financial statements and accompanying disclosures. We evaluate our estimates on a continuous basis. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances. The actual amounts may vary from the estimates used in the preparation of the accompanying consolidated financial statements.
Cash and Cash Equivalents and Investments. Cash and cash equivalents consist of all cash balances, including money market funds, time deposits, certificates of deposits and commercial paper that have a maturity, at the date of purchase, of 90 days or less.
We determine the appropriate classification of our investments in marketable securities at the date of purchase and reevaluate such designation at each balance sheet date. We classify and account for our marketable debt securities as either available-for-sale or held-to-maturity. After consideration of our risk versus reward objectives, as well as our liquidity requirements, we may sell our available-for-sale securities prior to their stated maturities. We classify these marketable securities with maturities at the date of purchase beyond 90 days as short-term investments based on their highly liquid nature and because such marketable securities represent an investment of cash that is available for current operations. Available-for-sale securities are reported at fair value with changes in unrealized gains and losses recorded as a separate component of "Accumulated other comprehensive income (loss)" on the consolidated statements of financial position until realized. We determine the cost of the securities sold based on the specific identification method. Our held-to-maturity investment securities are financial instruments that we have the intent and ability to hold to maturity and we classify these securities with maturities less than one year as short-term investments. Any held-to-maturity investment securities with maturities beyond one year from the balance sheet date are classified as long-term investments. Held-to-maturity securities are reported at amortized cost. Interest and amortization of premiums and discounts for debt securities are included in interest income.

For available-for-sale debt securities, if we do not intend to sell the security or it is not more likely than not that we will be required to sell the security before recovery of our amortized cost, we evaluate qualitative criteria, such as the financial health of and specific prospects for the issuer, to determine whether we do not expect to recover the amortized cost basis of the security. We also evaluate quantitative criteria including determining whether there has been an adverse change in expected future cash flows. If we do not expect to recover the entire amortized cost basis of the security, we consider the security to contain an expected credit loss, and we record the difference between the security’s amortized cost basis and its recoverable amount in earnings as an allowance for credit loss and the difference between the security’s recoverable amount and fair value in other comprehensive income. If we intend to sell the security or it is more likely than not we will be required to sell the security before recovery of its amortized cost basis, the security is considered impaired, and we recognize the entire difference between the security’s amortized cost basis and its fair value in earnings.
On initial recognition and on an ongoing basis, we evaluate our held-to-maturity investment securities for expected credit losses collectively when they share similar risk characteristics or individually, when the risk characteristics are different. The allowance for expected credit losses is determined using our historical loss experience. We monitor the credit ratings of the securities in our portfolio to evaluate the need for any changes to the allowance. An increase or a decrease in the allowance for expected credit losses is recorded through income as a credit loss expense or a reversal thereof. The allowance for expected credit losses is presented as a deduction from the amortized cost. A held-to-maturity investment security is written off when deemed uncollectible.
Financial Assets and Liabilities. Cash and certain cash equivalents, time deposits, trade receivables, accounts payable and other accrued liabilities are short-term in nature and, accordingly, their carrying values approximate fair value.
Property and Equipment. Property and equipment are stated at cost, net of accumulated depreciation. Depreciation is calculated on a straight-line basis over the estimated useful lives of the assets. Leasehold improvements are amortized on a straight-line basis over the shorter of the term of the lease or the estimated useful life of the asset. Deposits paid towards acquisition of long-lived assets and the cost of assets not put in use by the balance sheet date are disclosed under the caption "Capital work-in-progress" in Note 6.
Leases. Our lease asset classes primarily consist of operating leases for office space, data centers and IT equipment. At inception of a contract, we determine whether a contract contains a lease, and if a lease is identified, whether it is an operating or finance lease. In determining whether a contract contains a lease we consider whether (1) we have the right to obtain substantially all of the economic benefits from the use of the asset throughout the term of the contract, (2) we have the right to direct how and for what purpose the asset is used throughout the term of the contract and (3) we have the right to operate the asset throughout the term of the contract without the lessor having the right to change the terms of the contract. Some of our lease agreements contain both lease and non-lease components that we account for as a single lease component for all of our lease asset classes.
Our ROU lease assets represent our right to use an underlying asset for the lease term and may include any advance lease payments made and any initial direct costs and exclude lease incentives. Our lease liabilities represent our obligation to make lease payments arising from the terms of the lease. ROU lease assets and lease liabilities are recognized at the commencement of the lease and are calculated using the present value of lease payments over the lease term. Typically, our lease agreements do not provide sufficient detail to determine the rate implicit in the lease. Therefore, we use our estimated country-specific incremental borrowing rate based on information available at the commencement date of the lease to calculate the present value of the lease payments. In estimating our country-specific incremental borrowing rates, we consider market rates of comparable collateralized borrowings for similar terms. Our lease terms may include the option to extend or terminate the lease before the end of the contractual lease term. Our ROU lease assets and lease liabilities include these options when it is reasonably certain that they will be exercised.
A portion of our real estate lease costs is subject to annual changes in the CPI. Changes in CPI subsequent to the lease commencement are treated as variable lease payments and are recognized in the period in which the obligation for those payments is incurred. Other variable lease costs primarily relate to adjustments for common area maintenance, utilities, property tax and lease concessions. These variable costs are recognized in the period in which the obligation is incurred.

We elect not to recognize ROU assets and lease liabilities for short-term leases with a term equal to or less than 12 months. We recognize the lease payments in our income statement on a straight-line basis over the lease term and variable lease payments in the period in which the obligation for those payments is incurred.

Both ROU assets and finance lease assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the related asset group may not be recoverable.
Internal Use Software. We capitalize certain costs that are incurred to purchase, develop and implement internal-use software during the application development phase, which primarily include coding, testing and certain data conversion activities. Capitalized costs are amortized on a straight-line basis over the useful life of the software. Costs incurred in performing planning and post-implementation activities are expensed as incurred.
Cloud Computing Arrangements. We defer certain implementation costs that are incurred when implementing cloud computing service or software-as-a-service arrangements, which primarily include efforts associated with configuration and development activities. Once the service is ready for use, deferred costs are expensed over the term of the arrangement and recognized in income from operations.
Software to be Sold, Leased or Marketed. We capitalize costs incurred after technological feasibility is reached but before software is available for general release to clients, which primarily include coding and testing activities. Once the product is ready for general release, capitalized costs are amortized over the useful life of the software.
Business Combinations. We account for business combinations using the acquisition method, which requires the identification of the acquirer, the determination of the acquisition date and the allocation of the purchase price paid by the acquirer to the identifiable tangible and intangible assets acquired, the liabilities assumed, including any contingent consideration and any noncontrolling interest in the acquiree at their acquisition date fair values. Goodwill represents the excess of the purchase price over the fair value of net assets acquired, including the amount assigned to identifiable intangible assets. Identifiable intangible assets with finite lives are amortized over their expected useful lives. Acquisition-related costs are expensed in the periods in which the costs are incurred. The results of operations of acquired businesses are included in our consolidated financial statements from the acquisition date.
Equity Method Investments. Equity investments that give us the ability to exercise significant influence, but not control, over an investee are accounted for using the equity method of accounting and recorded in the caption "Long-term investments" on our consolidated statements of financial position. Equity method investments are initially recorded at cost. We periodically review the carrying value of our equity method investments to determine if there has been an other-than-temporary decline in the carrying value. The investment balance is increased to reflect contributions and our share of earnings and decreased to reflect our share of losses, distributions and other-than-temporary impairments. Our proportionate share of the net income or loss of the investee is recorded in the caption "Income (loss) from equity method investments" on our consolidated statements of operations.
Long-lived Assets and Finite-lived Intangible Assets. We review long-lived assets and certain finite-lived intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset group may not be recoverable. The carrying amount may not be recoverable when the sum of undiscounted expected future cash flows is less than the carrying amount of such asset groups. The impairment loss is determined as the amount by which the carrying amount of the asset group exceeds its fair value. Intangible assets consist primarily of customer relationships and developed technology, which are being amortized on a straight-line basis over their estimated useful lives.

Goodwill and Indefinite-lived Intangible Assets. At each acquisition date, we allocate goodwill and intangible assets to our reporting units based on how we expect each reporting unit to benefit from the respective business combination. Our seven industry-based operating segments are our reporting units. We evaluate goodwill and indefinite-lived intangible assets for impairment at least annually, or as circumstances warrant. Goodwill is evaluated at the reporting unit level by comparing the fair value of the reporting unit with its carrying amount including goodwill. An impairment of goodwill exists if the carrying amount of the reporting unit exceeds its fair value. The impairment loss is the amount by which the carrying amount exceeds the reporting unit’s fair value, limited to the total amount of goodwill allocated to that reporting unit. For indefinite-lived intangible assets, if our qualitative assessment indicates that it is more-likely-than-not that an indefinite-lived intangible asset is impaired, we test the assets for impairment by comparing the fair value of such assets to their carrying value. If an impairment is indicated, a write down to the fair value of indefinite-lived intangible asset is recorded.
Stock Repurchase Program. Under the Board of Directors authorized stock repurchase program, the Company is authorized to repurchase its Class A common stock through open market purchases, including under a 10b5-1 Plan, in accordance with applicable federal securities laws. We account for the repurchased shares as constructively retired. Shares are returned to the status of authorized and unissued shares at the time of repurchase. To reflect share repurchases in the consolidated statements of financial position, we (1) reduce common stock for the par value of the shares, (2) reduce additional paid-in capital for the amount in excess of par during the period in which the shares are repurchased and (3) record any residual amount in excess of available additional paid-in capital as a reduction to retained earnings.
Revenue Recognition. We recognize revenues as we transfer control of deliverables (products, solutions and services) to our clients in an amount reflecting the consideration to which we expect to be entitled. To recognize revenues, we apply the following five step approach: (1) identify the contract with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract, and (5) recognize revenues when a performance obligation is satisfied. We account for a contract when it has approval and commitment from all parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectibility of consideration is probable. We apply judgment in determining the customer’s ability and intention to pay based on a variety of factors including the customer’s historical payment experience.
For performance obligations where control is transferred over time, revenues are recognized based on the extent of progress towards completion of the performance obligation. The selection of the method to measure progress towards completion requires judgment and is based primarily on the nature of the deliverables to be provided.
Revenues related to fixed-price contracts for application development and systems integration services, consulting or other technology services are recognized as the service is performed using the cost-to-cost method, under which the total value of revenues is recognized on the basis of the percentage that each contract’s total labor cost to date bears to the total expected labor costs. Revenues related to fixed-price application maintenance, quality engineering and assurance as well as business process services are recognized based on our right to invoice for services performed for contracts in which the invoicing is representative of the value being delivered. If our invoicing is not consistent with the value delivered, revenues are recognized as the service is performed based on the cost-to-cost method described above. The cost-to-cost method requires estimation of future costs, which is updated as the project progresses to reflect the latest available information. Such estimates and changes in estimates involve the use of judgment. The cumulative impact of any revision in estimates is reflected in the financial reporting period in which the change in estimate becomes known and any anticipated losses on contracts are recognized immediately, where appropriate.

Revenues related to fixed-price hosting and infrastructure and security services are recognized based on our right to invoice for services performed for contracts in which the invoicing is representative of the value being delivered. If our invoicing is not consistent with the value delivered, revenues are recognized on a straight-line basis unless revenues are earned and obligations are fulfilled in a different pattern. The revenue recognition method applied to the types of contracts described above provides the most faithful depiction of performance towards satisfaction of our performance obligations; for example, the cost-to-cost method is used when the value of services provided to the customer is best represented by the costs expended to deliver those services.

Revenues related to our time-and-materials, transaction-based or volume-based contracts are recognized over the period the services are provided either using an output method such as labor hours, or a method that is otherwise consistent with the way in which value is delivered to the customer.

Revenues related to our non-hosted software license arrangements that do not require significant modification or customization of the underlying software are recognized when the software is delivered as control is transferred at a point in time. For software license arrangements that require significant functionality enhancements or modification of the software, revenues for the software license and related services are recognized as the services are performed in accordance with the methods applicable to application development and systems integration services described above. In software hosting arrangements, the rights provided to the customer, such as ownership of a license, contract termination provisions and the feasibility of the client to operate the software, are considered in determining whether the arrangement includes a license or a service. Sales and usage-based fees promised in exchange for licenses of intellectual property are not recognized as revenue until the uncertainty related to the variable amounts is resolved. Revenues related to software maintenance and support are generally recognized on a straight-line basis over the contract period.

Incentive revenues, volume discounts, or any other form of variable consideration is estimated using either the sum of probability weighted amounts in a range of possible consideration amounts (expected value) or the single most likely amount in a range of possible consideration amounts (most likely amount), depending on which method better predicts the amount of consideration to which we may be entitled. We include in the transaction price variable consideration only to the extent it is probable that a significant reversal of revenues recognized will not occur when the uncertainty associated with the variable consideration is resolved. Our estimates of variable consideration and determination of whether and when to include estimated amounts in the transaction price may involve judgment and are based largely on an assessment of our anticipated performance and all information that is reasonably available to us.

Revenues also include the reimbursement of out-of-pocket expenses. Our warranties generally provide a customer with assurance that the related deliverable will function as the parties intended because it complies with agreed-upon specifications and are therefore not considered an additional performance obligation in the contract.

We may enter into arrangements that consist of multiple performance obligations. Such arrangements may include any combination of our deliverables. To the extent a contract includes multiple promised deliverables, we apply judgment to determine whether promised deliverables are capable of being distinct and are distinct in the context of the contract. If these criteria are not met, the promised deliverables are accounted for as a combined performance obligation. For arrangements with multiple distinct performance obligations, we allocate consideration among the performance obligations based on their relative standalone selling price. Standalone selling price is the price at which we would sell a promised good or service separately to the customer. When not directly observable, we typically estimate standalone selling price by using the expected cost plus margin or, in limited circumstances, the residual value approach. We typically establish a standalone selling price range for our deliverables, which is reassessed on a periodic basis or when facts and circumstances change.
We assess the timing of the transfer of goods or services to the customer as compared to the timing of payments to determine whether a significant financing component exists. As a practical expedient, we do not assess the existence of a significant financing component when the difference between payment and transfer of deliverables is a year or less. If the difference in timing arises for reasons other than the provision of finance to either the customer or us, no financing component is deemed to exist. The primary purpose of our invoicing terms is to provide customers with simplified and predictable ways of purchasing our services, not to receive or provide financing from or to customers. We do not consider set up or transition fees paid upfront by our customers to represent a financing component, as such fees are required to encourage customer commitment to the project and protect us from early termination of the contract.

Our contracts may be modified to add, remove or change existing performance obligations. The accounting for modifications to our contracts involves assessing whether the services added to an existing contract are distinct and whether the pricing is at the standalone selling price. Services added that are not distinct are accounted for on a cumulative catch up basis, while those that are distinct are accounted for prospectively, either as a separate contract if the additional services are priced at the standalone selling price, or as a termination of the existing contract and creation of a new contract if not priced at the standalone selling price. Services added to our application development and systems integration service contracts are typically not distinct, while services added to our other contracts, including application maintenance, quality engineering and assurance as well as business process services contracts, are typically distinct.
From time to time, we may enter into arrangements with third party suppliers to resell products or services. In such cases, we evaluate whether we are the principal (i.e., report revenues on a gross basis) or agent (i.e., report revenues on a net basis). In doing so, we evaluate whether we control the good or service before it is transferred to the customer. If we control the good or service before it is transferred to the customer, we are the principal; if not, we are the agent. Determining whether we control the good or service before it is transferred to the customer requires significant judgment.
Trade Accounts Receivable, Contract Assets and Contract Liabilities. We classify our right to consideration in exchange for deliverables as either a receivable or a contract asset. A receivable is a right to consideration that is unconditional (i.e., only the passage of time is required before payment is due). For example, we recognize a receivable for revenues related to our time and materials and transaction or volume-based contracts when earned regardless of whether amounts have been billed. We present such receivables in "Trade accounts receivable, net" in our consolidated statements of financial position at their net estimated realizable value. A contract asset is a right to consideration that is conditional upon factors other than the passage of time. Contract assets are presented in "Other current assets" or "Other noncurrent assets" in our consolidated statements of financial position, based on the expected timing of billing, and primarily relate to unbilled amounts on fixed-price contracts utilizing the cost-to-cost method of revenue recognition. Our contract liabilities, or deferred revenue, consist of advance payments from clients and billings in excess of revenues recognized. We classify deferred revenue as current or noncurrent based on the timing of when we expect to recognize the revenues.
Our contract assets and contract liabilities are reported on a net basis by contract at the end of each reporting period. The difference between the opening and closing balances of our contract assets and contract liabilities primarily results from the timing difference between our performance obligations and the client’s payment. We receive payments from clients based on the terms established in our contracts, which vary from contract to contract.
Allowance for Credit Losses. We calculate expected credit losses for our trade accounts receivable and contract assets. Expected credit losses include losses expected based on known credit issues with specific customers as well as a general expected credit loss allowance based on relevant information, including historical loss rates, current conditions, and reasonable economic forecasts that affect collectibility. We update our allowance for credit losses on a quarterly basis with changes in the allowance recognized in income from operations.
Costs to Fulfill. Recurring operating costs for contracts with customers are recognized as incurred. Certain eligible, nonrecurring costs (i.e., set-up or transition costs) are capitalized when such costs (1) relate directly to the contract, (2) generate or enhance resources of the Company that will be used in satisfying the performance obligation in the future, and (3) are expected to be recovered. These costs are expensed ratably over the estimated life of the customer relationship, including expected contract renewals. In determining the estimated life of the customer relationship, we evaluate the average contract term on a portfolio basis by nature of the services to be provided, and apply judgment in evaluating the rate of technological and industry change. Capitalized amounts are monitored regularly for impairment. Impairment losses are recorded when projected remaining consideration that has not already been recognized as revenue less costs related to the services being provided are not sufficient to recover the carrying amount of the capitalized costs to fulfill. Costs to fulfill are recorded in "Other noncurrent assets" in our consolidated statements of financial position and the amortization expense of costs to fulfill is included in "Cost of revenues" in our consolidated statements of operations.
Stock-Based Compensation. Stock-based compensation expense for awards of equity instruments to employees and non-employee directors is determined based on the grant date fair value of those awards. We recognize these compensation costs net of an estimated forfeiture rate over the requisite service period of the award. Forfeitures are estimated on the date of grant and revised if actual or expected forfeiture activity differs materially from original estimates. Stock-based compensation expense relating to RSUs and PSUs is recognized as shares vest over the requisite service period. If the minimum performance targets are not met, no compensation cost is recognized and any recognized compensation cost is reversed, except for awards subject to a market condition. The fair value of RSUs and PSUs is determined based on the number of stock units granted and the quoted price of our stock at the date of grant. The fair value of PSUs granted subject to a market condition is determined using a Monte Carlo valuation model.
Foreign Currency. The assets and liabilities of our foreign subsidiaries whose functional currency is not the U.S. dollar are translated into U.S. dollars at current exchange rates while revenues and expenses are translated at average monthly exchange rates. The resulting translation adjustments are recorded in the caption "Accumulated other comprehensive income (loss)" on the consolidated statements of financial position.
Foreign currency transactions and balances are those that are denominated in a currency other than the entity’s functional currency. An entity's functional currency is the currency of the primary economic environment in which it operates. The U.S. dollar is the functional currency for some of our foreign subsidiaries. For these subsidiaries, transactions and balances denominated in the local currency are foreign currency transactions. Foreign currency transactions and balances related to non-monetary assets and liabilities are remeasured to the functional currency of the entity at historical exchange rates while monetary assets and liabilities are remeasured to the functional currency of the entity at current exchange rates. Foreign currency exchange gains or losses from remeasurement are included in the caption "Foreign currency exchange gain (losses), net" on our consolidated statements of operations together with gains or losses on our undesignated foreign currency hedges.
Derivative Financial Instruments. Derivative financial instruments are recorded on our consolidated statements of financial position as either an asset or liability measured at its fair value as of the reporting date. Our derivative financial instruments consist primarily of foreign exchange forward and option contracts. For derivative financial instruments to qualify for hedge accounting, the following criteria must be met: (1) the hedging instrument must be designated as a hedge; (2) the hedged exposure must be specifically identifiable and must expose us to risk; and (3) it must be expected that a change in fair value of the hedging instrument and an opposite change in the fair value of the hedged exposure will have a high degree of correlation. Changes in our derivatives’ fair values are recognized in net income unless specific hedge accounting and documentation criteria are met (i.e., the instruments are designated and accounted for as hedges). We record the effective portion of the unrealized gains and losses on our derivative financial instruments that are designated as cash flow hedges in the caption "Accumulated other comprehensive income (loss)" in the consolidated statements of financial position. Any ineffectiveness or excluded portion of a designated cash flow hedge is recognized in net income. Upon occurrence of the hedged transaction, the gains and losses on the derivative are recognized in net income.
Income Taxes. We provide for income taxes utilizing the asset and liability method of accounting. Under this method, deferred income taxes are recorded to reflect the tax consequences in future years of differences between the tax basis of assets and liabilities and their financial reporting amounts at each balance sheet date, based on enacted tax laws and statutory tax rates applicable to the periods in which the differences are expected to affect taxable income. If it is determined that it is more likely than not that future tax benefits associated with a deferred income tax asset will not be realized, a valuation allowance is provided. The effect of a change in tax rates on deferred income tax assets and liabilities is recognized in the provision for income taxes in the period that includes the enactment date.
Our provision for income taxes also includes the impact of provisions established for uncertain income tax positions, as well as any related penalties and interest. We adjust these reserves in light of changing facts and circumstances, such as the closing of a tax audit or the expiration of the applicable statute of limitations. To the extent that the final outcome of these matters differs from the amounts recorded, such differences will impact the provision for income taxes in the period in which such determination is made.
Earnings Per Share. Basic EPS is computed by dividing earnings available to common stockholders by the weighted-average number of common shares outstanding for the period. Diluted EPS includes all potential dilutive common stock in the weighted average shares outstanding. We excluded less than 1 million of anti-dilutive shares in each of 2023, 2022 and 2021 from our diluted EPS calculation. We include PSUs in the dilutive common shares when they become contingently issuable per the authoritative guidance and exclude them when they are not contingently issuable.
Restructuring Charges. Restructuring charges principally consist of severance and related separation costs, facility exit costs and other related third-party costs necessary to execute the restructuring program. The Company accrues for severance and other related separation costs when it is probable that termination benefits will be paid and the amount is reasonably
estimable. Recognition of employee severance and other separation costs is also dependent on requirements established by severance policy, statutory laws, or historical experience. Facility exit costs generally reflect the accelerated lease expense for right-of-use assets, expected lease termination costs, and asset impairments in connection with closure of certain sites, net of gains on exit-related disposals.
Restructuring costs are recorded in “Restructuring charges” in the consolidated statements of operations. The restructuring liability related to accrued employee separation costs is included in "Accrued expenses and other current liabilities" in the consolidated statements of financial position. At the end of each reporting period, the Company evaluates the remaining accrued balances to ensure these balances are properly stated.

Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures

Annual period starting in 2024 and interim periods starting in 2025


Retrospective basis

The new standard requires enhanced segment disclosures but does not change the definition of a segment for the guidance for determining a reportable segment. The amendments require disclosure of significant segment expenses regularly provided to the CODM included within segment operating profit or loss and a description of how the CODM utilizes segment operating profit or loss to assess segment performance and allocating resources. The new standard also allows companies to disclose multiple measures of segment profit or loss if those measures are used to allocate resources.
The Company is currently evaluating the impact of the new standard on its related disclosures.

Disaggregation of Revenues

The tables below present disaggregated revenues from contracts with clients by client location, service line and contract type for each of our reportable business segments. We believe this disaggregation best depicts how the nature, amount, timing and uncertainty of our revenues and cash flows are affected by industry, market and other economic factors. Our consulting and technology services include consulting, application development, systems integration, quality engineering and assurance services as well as software solutions and related services while our outsourcing services include application maintenance, infrastructure and security as well as business process services. Revenues are attributed to geographic regions based upon client location, which is the client's billing address. Substantially all revenues in our North America region relate to clients in the United States.

Business Combinations [Abstract]  
Business Combinations
Acquisitions completed during each of the three years ended December 31, 2023, 2022 and 2021 were not individually or in the aggregate material to our operations. Accordingly, pro forma results have not been presented. We have allocated the purchase price related to these transactions to tangible and intangible assets acquired and liabilities assumed, including goodwill, based on their estimated fair values. The primary items that generated goodwill are the value of the acquired assembled workforces and synergies between the acquired companies and us, neither of which qualify as an identifiable intangible asset.

2023
In 2023, we acquired 100% ownership in each of the following:
•certain net assets of OneSource Virtual, the professional and application management services business of OneSource Virtual, Inc. and OneSource Virtual (UK) Ltd., a leading provider of Workday services, solutions and products, acquired to complement our existing finance and human resources advisory implementation services related to Workday (acquired January 1, 2023), and
•Mobica, an IoT software engineering services provider, acquired to expand our IoT embedded software engineering capabilities (acquired March 10, 2023).

Goodwill from our acquisition of OneSource Virtual is expected to benefit all of our reportable segments and has been allocated as such. Goodwill from our acquisition of Mobica has been allocated to our Financial Services, Products and Resources and Communications, Media and Technology segments. For the year ended December 31, 2023, revenues from acquisitions completed in 2023, since the dates of acquisition, were $130 million. On December 30, 2022, $103 million was placed in an escrow account in advance of the closing date of our acquisition of certain net assets of OneSource Virtual on January 1, 2023. This balance was deemed to be restricted cash as of December 31, 2022 and was presented in "Other noncurrent assets" in our consolidated statement of financial position and as restricted cash in our consolidated statement of cash flows for the year ended December 31, 2022.
2022
In 2022, we acquired 100% ownership in each of the following:
•AustinCSI, a digital transformation consultancy specializing in enterprise cloud and data analytics advisory services, acquired to complement our technology and industry expertise (acquired December 15, 2022); and
•Utegration, a full service consulting and solutions provider specializing in SAP technology and SAP-certified products for the energy and utilities sectors, acquired to expand and strengthen our industry expertise in our SAP practice (acquired December 19, 2022).

Restructuring Charges [Abstract]  
Realignment Charges
In the second quarter of 2023, we initiated the NextGen program aimed at simplifying our operating model, optimizing corporate functions and consolidating and realigning office space to reflect the post-pandemic hybrid work environment. We expect the NextGen program to be completed by the end of 2024.
The total costs related to our NextGen program are reported in "Restructuring charges" in our audited consolidated statements of operations. We do not allocate these charges to individual segments in internal management reports used by the CODM.

Debt
In 2022, we entered into the Credit Agreement providing for the $650 million Term Loan and a $1,850 million unsecured revolving credit facility, which are each due to mature in October 2027. We are required under the Credit Agreement to make scheduled quarterly principal payments on the Term Loan.

The Credit Agreement requires interest to be paid, at our option, at either the Term Benchmark, Adjusted Daily Simple RFR or the ABR Rate (each as defined in the Credit Agreement), plus, in each case, an Applicable Margin (as defined in the Credit Agreement). Initially, the Applicable Margin is 0.875% with respect to Term Benchmark loans and RFR loans and 0.00% with respect to ABR loans. Subsequently, the Applicable Margin with respect to Term Benchmark loans and RFR loans will be determined quarterly and may range from 0.75% to 1.125%, depending on our public debt ratings or, if we have not received public debt ratings, from 0.875% to 1.125%, depending on our Leverage Ratio, which is the ratio of indebtedness for borrowed money to Consolidated EBITDA, as defined in the Credit Agreement. Since issuance of the Term Loan, the Term Loan has been a Term Benchmark loan.

The Credit Agreement contains customary affirmative and negative covenants as well as a financial covenant. The financial covenant is tested at the end of each fiscal quarter and requires us to maintain a Leverage Ratio not in excess of 3.50:1.00, or for a period of up to four quarters following certain material acquisitions, 3.75:1.00. We were in compliance with all debt covenants and representations of the Credit Agreement as of December 31, 2023.
In March 2023, our India subsidiary renewed its working capital facility at 15 billion Indian rupees ($180 million at the December 31, 2023 exchange rate). The facility requires us to repay any balances within 90 days from the date of disbursement. There is a 1.0% prepayment penalty applicable to payments made within 30 days of disbursement. This working capital facility contains affirmative and negative covenants and may be renewed annually. As of December 31, 2023, we have not borrowed funds under this facility or any of its predecessor facilities.
Short-term Debt
As of December 31, 2023 and 2022, we had $33 million and $8 million of short-term debt related to current maturities of our Term Loan, with a weighted average interest rate of 6.3% and 5.2%, respectively.

We are involved in two separate ongoing disputes with the ITD in connection with previously disclosed share repurchase transactions undertaken by CTS India in 2013 and 2016 to repurchase shares from its shareholders (non-Indian Cognizant entities) valued at $523 million and $2.8 billion, respectively.
The 2016 transaction was undertaken pursuant to a plan approved by the High Court in Chennai, India, and resulted in the payment of $135 million in Indian income taxes - an amount we believe includes all the applicable taxes owed for this transaction under Indian law. In March 2018, the ITD asserted that it is owed an additional 33 billion Indian rupees ($397 million at the December 31, 2023 exchange rate) on the 2016 transaction. We deposited 5 billion Indian rupees, representing 15% of the disputed tax amount related to the 2016 transaction, with the ITD. As of both December 31, 2023 and 2022, the deposit with the ITD was $60 million, presented in "Other noncurrent assets." Additionally, certain time deposits of CTS India were placed under lien in favor of the ITD, representing the remainder of the disputed tax amount. As of December 31, 2023 and 2022, the balance of deposits under lien was 30 billion Indian rupees, including previously earned interest, or $355 million and $357 million, respectively, as presented in "Long-term investments." As of December 31, 2023, $96 million of the $355 million deposits under lien were held in time deposits with a maturity of less than 30 days qualifying as cash equivalent instruments and thus are presented as restricted cash equivalents on the consolidated statement of cash flows for the year ended December 31, 2023.
In April 2020, we received a formal assessment from the ITD on the 2016 transaction, which was consistent with the ITD's previous assertions. Our appeal was ruled on unfavorably by the CITA in March 2022 and by the ITAT in September 2023. We filed an appeal against the order of the ITAT with the High Court. On January 8, 2024, the SCI ruled that, in order to proceed with the appeal, we must deposit 30 billion Indian rupees ($355 million at the December 31, 2023 exchange rate), representing the time deposits of CTS India under lien, on the condition that, if CTS India prevails at the High Court, the amount deposited will be returned to CTS India, along with interest accrued, within 4 weeks of the judgment. The SCI also requested the High Court to consider and dispose of the appeal as expeditiously as possible, preferably within 6 weeks of the January 8, 2024 ruling. We made the required deposit in January 2024.
The dispute in relation to the 2013 share repurchase transaction is also in litigation. At this time, the ITD has not made specific demands with regards to the 2013 transaction.

We continue to believe we have paid all applicable taxes owed on both the 2016 and the 2013 transactions and we continue to defend our positions with respect to both matters. Accordingly, we have not recorded any reserves for these matters as of December 31, 2023.

Our Indian subsidiaries are primarily export-oriented and, through March 31, 2022, benefited from certain income tax holiday benefits granted by the government of India for export activities conducted within SEZs. In December 2019, India enacted the India Tax Law, which enables Indian companies to elect to be taxed at a lower income tax rate of 25.17%, as compared to the otherwise applicable income tax rate of 34.94%. Once a company elects into the lower income tax rate, a company may not benefit from any income tax holidays associated with SEZs and certain other tax incentives and carryforwards, and may not reverse its election. We elected into the new tax regime starting with the India fiscal year beginning on April 1, 2022, and as a result, there was no impact from income tax holidays on our income tax provision or net income for the year ended December 31, 2023. For the years ended December 31, 2022 and 2021, the effect of the income tax holidays granted by the Indian government was to reduce the overall income tax provision and increase net income by $6 million and $36 million, respectively, and increase diluted EPS by $0.01 and $0.07, respectively.
During 2023, we reached an agreement with the IRS, which settled tax years 2017 and 2018, as well as a settlement related to U.S. state income taxes, each of which decreased our effective income tax rate for 2023.

Provisions enacted in the Tax Reform Act in December 2017 related to the capitalization of research and experimental expenditures became effective on January 1, 2022. These provisions require us to capitalize research and experimental expenditures and amortize them for tax purposes over five or fifteen years, depending on where the research is conducted. Previously these expenses could be deducted in the year incurred. The implementation of these provisions increased our deferred tax asset in the United States on a year-over-year basis by approximately $206 million and $300 million in 2023 and 2022, respectively.
We conduct business globally and file income tax returns in the United States, including federal and state, as well as various foreign jurisdictions. Tax years that remain subject to examination by the IRS are 2019 and onward, and years that remain subject to examination by state authorities vary by state. Years under examination by foreign tax authorities are 2003 and onward. In addition, transactions between our affiliated entities are arranged in accordance with applicable transfer pricing laws, regulations and relevant guidelines. As a result, and due to the interpretive nature of certain aspects of these laws and guidelines, we have pending applications for APAs before the taxing authorities in some of our most significant jurisdictions.
We record incremental tax expense, based upon the more-likely-than-not standard, for any uncertain tax positions. In addition, when applicable, we adjust the previously recorded income tax expense to reflect examination results when the position is effectively settled or otherwise resolved. Our ongoing evaluations of the more-likely-than-not outcomes of the examinations and related tax positions require judgment and can result in adjustments that increase or decrease our effective income tax rate, as well as impact our operating results. The specific timing of when the resolution of each tax position will be reached is uncertain.

Balance, end of year$260 $269 $194 
In the third quarter of 2022, we recognized an income tax benefit of $36 million related to a specific uncertain tax position that was previously unrecognized in our prior year consolidated financial statements. The recognition of the benefit in the third quarter of 2022 was based on management’s reassessment regarding whether this unrecognized tax benefit met the more-likely-than-not threshold in light of the lapse in the statute of limitations as to a portion of such benefit. In 2021, we reached an agreement with the IRS, which settled tax years 2012 through 2016. As a result of this settlement, in the first quarter of 2021, we recorded a $14 million discrete benefit to the provision for income taxes.
The unrecognized income tax benefits would affect our effective income tax rate, if recognized. While the Company believes uncertain tax positions may be settled or resolved within the next twelve months, it is difficult to estimate the income tax impact of these potential resolutions at this time. We recognize accrued interest and any penalties associated with uncertain tax positions as part of our provision for income taxes. The total amount of accrued net interest and penalties at both December 31, 2023 and 2022 was $33 million, and related to U.S. and foreign tax matters. The total amount of net interest and penalties recorded in the provision for income taxes in each of 2023, 2022 and 2021 was immaterial.

Derivative Financial Instruments
In the normal course of business, we use foreign exchange forward and option contracts to manage foreign currency exchange rate risk. Derivatives may give rise to credit risk from the possible non-performance by counterparties. Credit risk is limited to the fair value of those contracts that are favorable to us. We have limited our credit risk by limiting the amount of credit exposure with any one financial institution and conducting ongoing evaluation of the creditworthiness of the financial institutions with which we do business. In addition, all the assets and liabilities related to the foreign exchange derivative contracts set forth in the below table are subject to master netting arrangements, such as the International Swaps and Derivatives Association Master Agreement, with each individual counterparty. These master netting arrangements generally provide for net settlement of all outstanding contracts with the counterparty in the case of an event of default or a termination event. We have presented all the assets and liabilities related to the foreign exchange derivative contracts, as applicable, on a gross basis, with no offsets, in our consolidated statements of financial position. There is no financial collateral (including cash collateral) posted or received by us related to the foreign exchange derivative contracts.

Cash Flow Hedges
We have entered into a series of foreign exchange derivative contracts that are designated as cash flow hedges of Indian rupee denominated payments in India. These contracts are intended to partially offset the impact of movement of the Indian rupee against the U.S. dollar on future operating costs and are scheduled to mature each month during 2024 and 2025. The changes in fair value of these contracts are initially reported in "Accumulated other comprehensive income (loss)" in our consolidated statements of financial position and are subsequently reclassified to earnings within "Cost of revenues" and "Selling, general and administrative expenses" in our consolidated statements of operations in the same period that the forecasted Indian rupee denominated payments are recorded in earnings. As of December 31, 2023, we estimate that $6 million, net of tax, of the net gains related to derivatives designated as cash flow hedges reported in the caption "Accumulated other comprehensive income (loss)" in our consolidated statements of financial position is expected to be reclassified into earnings within the next 12 months.

Other Derivatives
We use foreign exchange forward contracts to provide an economic hedge against balance sheet exposures to certain monetary assets and liabilities denominated in currencies other than the functional currency of our foreign subsidiaries. We entered into foreign exchange forward contracts that are scheduled to mature in the first quarter of 2024. Realized gains or losses and changes in the estimated fair value of these derivative financial instruments are recorded in the caption "Foreign currency exchange gains (losses), net" in our consolidated statements of operations.

Fair Value Measurements

Fair Value Disclosures [Abstract]  
Fair Value Measurements
We measure our cash equivalents, certain investments, contingent consideration liabilities and foreign exchange forward and option contracts at fair value. Fair value is the exit price, or the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants as of the measurement date. The fair value hierarchy is based on inputs to valuation techniques that are used to measure fair value that are either observable or unobservable. Observable inputs reflect assumptions market participants would use in pricing an asset or liability based on market data obtained from independent sources while unobservable inputs reflect a reporting entity’s pricing based upon their own market assumptions.
The fair value hierarchy consists of the following three levels:
•Level 1 – Inputs are quoted prices in active markets for identical assets or liabilities.
•Level 2 – Inputs are quoted prices for similar assets or liabilities in an active market, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable and market-corroborated inputs which are derived principally from or corroborated by observable market data.
•Level 3 – Inputs are derived from valuation techniques in which one or more significant inputs or value drivers are unobservable.

We measure the fair value of money market funds based on quoted prices in active markets for identical assets and measure the fair value of our equity investment security based on the published daily net asset value at which investors can freely subscribe to or redeem from the fund. The fair value of certificates of deposit and commercial paper is measured based on relevant trade data, dealer quotes, or model-driven valuations using significant inputs derived from or corroborated by observable market data, such as yield curves and credit spreads. The carrying value of the time deposits approximated fair value as of each of December 31, 2023 and 2022.
We estimate the fair value of each foreign exchange forward contract by using a present value of expected cash flows model. This model calculates the difference between the current market forward price and the contracted forward price for each foreign exchange forward contract and applies the difference in the rates to each outstanding contract. The market forward rates include a discount and credit risk factor. We estimate the fair value of each foreign exchange option contract by using a variant of the Black-Scholes model. This model uses present value techniques and reflects the time value and intrinsic value based on
observable market rates.
We estimate the fair value of contingent consideration liabilities associated with acquisitions using a variation of the income approach, which utilizes one or more significant inputs that are unobservable. This approach calculates the fair value of such liabilities based on the probability-weighted expected performance of the acquired entity against the target performance metric, discounted to present value when appropriate.
During the years ended December 31, 2023, 2022 and 2021 there were no transfers among Level 1, Level 2 or Level 3 financial assets and liabilities.

Commitments and Contingencies Disclosure [Abstract]  
Commitments and Contingencies
We are involved in various claims and legal proceedings arising in the ordinary course of business. We accrue a liability when a loss is considered probable and the amount can be reasonably estimated. When a material loss contingency is reasonably possible but not probable, we do not record a liability, but instead disclose the nature and the amount of the claim, and an estimate of the loss or range of loss, if such an estimate can be made. Legal fees are expensed as incurred. While we do not expect that the ultimate resolution of any existing claims and proceedings (other than the specific matters described below, if decided adversely), individually or in the aggregate, will have a material adverse effect on our financial position, an unfavorable outcome in some or all of these proceedings could have a material adverse impact on results of operations or cash flows for a particular period. This assessment is based on our current understanding of relevant facts and circumstances. As such, our view of these matters is subject to inherent uncertainties and may change in the future.

On January 15, 2015, Syntel sued TriZetto and Cognizant in the USDC-SDNY. Syntel’s complaint alleged breach of contract against TriZetto, and tortious interference and misappropriation of trade secrets against Cognizant and TriZetto, stemming from Cognizant’s hiring of certain former Syntel employees. Cognizant and TriZetto countersued on March 23, 2015, for breach of contract, misappropriation of trade secrets and tortious interference, based on Syntel’s misuse of TriZetto confidential information and abandonment of contractual obligations. Cognizant and TriZetto subsequently added federal DTSA and copyright infringement claims for Syntel’s misuse of TriZetto’s proprietary technology. The parties’ claims were narrowed by the court and the case was tried before a jury, which on October 27, 2020, returned a verdict in favor of Cognizant in the amount of $855 million, including $570 million in punitive damages. On April 20, 2021, the USDC-SDNY issued a post-trial order that, among other things, affirmed the jury’s award of $285 million in actual damages, but reduced the award of punitive damages from $570 million to $285 million, thereby reducing the overall damages award from $855 million to $570 million. The USDC-SDNY subsequently issued a final judgment consistent with the April 20th order. On May 26, 2021, Syntel filed a notice of appeal to the Second Circuit, and on June 3, 2021 the USDC-SDNY stayed execution of judgment pending appeal. On May 25, 2023, the Second Circuit issued an opinion affirming in part and vacating in part the judgment of the USDC-SDNY and remanding the case for further proceedings consistent with its opinion. The Second Circuit affirmed the judgment in all respects on liability but vacated the $570 million award that had been based on avoided development costs under the DTSA, and it remanded the case to the USDC-SDNY for further evaluation of damages. On June 23, 2023, the Second Circuit issued its mandate returning the case to the USDC-SDNY, and the proceedings there regarding damages remain ongoing. We will not record any gain in our financial statements until it becomes realizable.

On February 28, 2019, a ruling of the SCI interpreting the India Defined Contribution Obligation altered historical understandings of the obligation, extending it to cover additional portions of the employee’s income. As a result, the ongoing contributions of our affected employees and the Company were required to be increased. In the first quarter of 2019, we accrued $117 million with respect to prior periods, assuming retroactive application of the SCI’s ruling, in "Selling, general and administrative expenses" in our audited consolidated statement of operations. There is significant uncertainty as to how the liability should be calculated as it is impacted by multiple variables, including the period of assessment, the application with respect to certain current and former employees and whether interest and penalties may be assessed. Since the ruling, a variety of trade associations and industry groups have advocated to the Indian government, highlighting the harm to the information technology sector, other industries and job growth in India that would result from a retroactive application of the ruling. It is possible the Indian government will review the matter and there is a substantial question as to whether the Indian government will apply the SCI’s ruling on a retroactive basis. As such, the ultimate amount of our obligation may be materially different from the amount accrued.

On October 31, 2016, November 15, 2016 and November 18, 2016, three putative shareholder derivative complaints were filed in New Jersey Superior Court, Bergen County, naming us, all of our then current directors and certain of our current and former officers at that time as defendants. These actions were consolidated in an order dated January 24, 2017. The complaints assert claims for breach of fiduciary duty, corporate waste, unjust enrichment, abuse of control, mismanagement, and/or insider selling by defendants. On April 26, 2017, the New Jersey Superior Court deferred further proceedings by dismissing the consolidated putative shareholder derivative litigation without prejudice but permitting the parties to file a motion to vacate the dismissal in the future.

On February 22, 2017, April 7, 2017, May 10, 2017 and March 11, 2019, four additional putative shareholder derivative complaints were filed in the USDC-NJ, naming us and certain of our current and former directors and officers at that time as defendants. These actions were consolidated in an order dated May 14, 2019. On August 3, 2020, lead plaintiffs filed a consolidated amended complaint. The consolidated amended complaint asserts claims similar to those in the previously-filed putative shareholder derivative actions. On February 14, 2022, we and certain of our current and former directors and officers moved to dismiss the consolidated amended complaint. On September 27, 2022, the USDC-NJ granted those motions and
dismissed the consolidated amended complaint in its entirety with prejudice. Plaintiffs filed a notice of appeal on October 27, 2022.

On June 1, 2021, an eighth putative shareholder derivative complaint was filed in the USDC-NJ, naming us and certain of our current and former directors and officers at that time as defendants. The complaint asserts claims similar to those in the previously-filed putative shareholder derivative actions. On March 31, 2022, we and certain of our current and former directors and officers moved to dismiss the complaint. On November 30, 2022, the USDC-NJ denied without prejudice those motions. The USDC-NJ ordered the parties to conduct limited discovery related to the issue of whether our board of directors wrongfully refused the plaintiff’s earlier litigation demand and, after the conclusion of such limited discovery, to file targeted motions for summary judgment on the issue of wrongful refusal.
We are presently unable to predict the duration, scope or result of the putative shareholder derivative actions. Although the Company continues to defend the putative shareholder derivative actions vigorously, these lawsuits are subject to inherent uncertainties, the actual cost of such litigation will depend upon many unknown factors and the outcome of the litigation is necessarily uncertain.
We have indemnification and expense advancement obligations pursuant to our bylaws and indemnification agreements with respect to certain current and former members of senior management and the Company’s board of directors. In connection with the matters that were the subject of our previously disclosed internal investigation, the DOJ and SEC investigations and the related litigation, we have received and expect to continue to receive requests under such indemnification agreements and our bylaws to provide funds for legal fees and other expenses. There are no amounts remaining available to us under applicable insurance policies for our ongoing indemnification and advancement obligations with respect to certain of our current and former officers and directors or incremental legal fees and other expenses related to the above matters.

See Note 11 for information relating to the ITD Dispute.
Many of our engagements involve projects that are critical to the operations of our clients’ business and provide benefits that are difficult to quantify. Any failure in a client’s systems or our failure to meet our contractual obligations to our clients, including any breach involving a client’s confidential information or sensitive data, or our obligations under applicable laws or regulations could result in a claim for substantial damages against us, regardless of our responsibility for such failure. Although we attempt to contractually limit our liability for damages arising from negligent acts, errors, mistakes, or omissions in rendering our services, there can be no assurance that the limitations of liability set forth in our contracts will be enforceable in all instances or will otherwise protect us from liability for damages. Although we have general liability insurance coverage, including coverage for errors or omissions, we retain a significant portion of risk through our insurance deductibles and there can be no assurance that such coverage will cover all types of claims, continue to be available on reasonable terms or will be available in sufficient amounts to cover one or more large claims, or that the insurer will not disclaim coverage as to any future claim. The successful assertion of one or more large claims against us that exceed or are not covered by our insurance coverage or changes in our insurance policies, including premium increases or the imposition of large deductible or co-insurance requirements, could have a material adverse effect on our business, results of operations, financial position and cash flows for a particular period.
In the normal course of business and in conjunction with certain client engagements, we have entered into contractual arrangements through which we may be obligated to indemnify clients or other parties with whom we conduct business with respect to certain matters. These arrangements can include provisions whereby we agree to hold the indemnified party and certain of their affiliated entities harmless with respect to third-party claims related to such matters as our breach of certain representations or covenants, our intellectual property infringement, our gross negligence or willful misconduct or certain other claims made against certain parties. Payments by us under any of these arrangements are generally conditioned on the client making a claim and providing us with full control over the defense and settlement of such claim. It is not possible to determine the maximum potential liability under these indemnification agreements due to the unique facts and circumstances involved in each particular agreement. Historically, we have not made material payments under these indemnification agreements and therefore they have not had a material impact on our operating results, financial position, or cash flows. However, if events arise requiring us to make payment for indemnification claims under our indemnification obligations in contracts we have entered, such payments could have a material adverse effect on our business, results of operations, financial position and cash flows for a particular period.

Employee Benefits
We contribute to defined contribution plans, including 401(k) savings and supplemental retirement plans in the United States. Total expenses for our contributions to these plans, excluding the India plans described below, were $185 million, $172 million and $135 million for the years ended December 31, 2023, 2022 and 2021, respectively.
In addition, we maintain employee benefit plans that cover substantially all India-based employees. The employees’ provident fund, pension and family pension plans are statutorily defined contribution retirement benefit plans. Under the plans, employees contribute up to 12.0% of their eligible compensation, which is matched by an equal contribution by the Company. For these plans, we recognized a contribution expense of $149 million, $143 million and $121 million for the years ended December 31, 2023, 2022 and 2021, respectively.
We also maintain a gratuity plan in India that is a statutory post-employment benefit plan providing defined lump sum benefits. We make annual contributions to the employees’ gratuity fund established with a government-owned insurance corporation to fund a portion of the estimated obligation. Our liability for the gratuity plan reflected the undiscounted benefit obligation payable as of the balance sheet date, which was based upon the employees’ salary and years of service. As of December 31, 2023 and 2022, the amount accrued under the gratuity plan was $130 million and $99 million, which is net of fund assets of $221 million and $206 million, respectively. Expense recognized by us was $56 million, $45 million and $70 million for the years ended December 31, 2023, 2022 and 2021, respectively.

Our 2023 Incentive Plan provides for the issuance of a total of 25.0 million shares of Class A common stock to eligible employees, less (i) the number of shares granted under the 2017 Incentive Plan between March 24, 2023 and June 6, 2023, plus (ii) any shares subject to awards under the prior 2017 and 2009 Incentive Plans that are forfeited after June 6, 2023. The Purchase Plan provides for the issuance of up to 50.0 million shares of Class A common stock to eligible employees. The 2023 Incentive Plan does not affect any awards outstanding under the prior plans. As of December 31, 2023, we have 25.1 million and 11.5 million shares available for grant under the 2023 Incentive Plan and the Purchase Plan, respectively.
The allocation of total stock-based compensation expense between cost of revenues, selling, general and administrative expenses and restructuring charges as well as the related income tax benefit were as follows for the three years ended December 31:

We granted PSUs that vest over periods up to four years to employees, including our executive officers. The vesting of PSUs is contingent on meeting certain financial performance targets, market conditions and continued service. A summary of the activity for PSUs granted under our stock-based compensation plans as of December 31, 2023 and changes during the year then ended is presented below.

As of December 31, 2023, $13 million of the total remaining unrecognized stock-based compensation cost related to PSUs is expected to be recognized over the weighted-average remaining requisite service period of 1.3 years.

All RSUs and PSUs have dividend equivalent rights, which entitle holders to the same dividend value per share as holders of common stock. Dividend equivalent rights are subject to the same vesting and other terms and conditions as the corresponding unvested RSUs and PSUs and are accumulated and paid when the underlying shares vest.
Purchase Plan
For the years ended December 31, 2023 and 2022, the Purchase Plan provided for eligible employees to purchase shares of Class A common stock at a price equal to 95% of the fair market value per share of our Class A common stock on the last date of the purchase period. This plan has been deemed non-compensatory and, therefore, no compensation expense has been recorded. During the years ended December 31, 2023 and 2022, we issued 1.1 million shares and 1.3 million shares, respectively, of Class A common stock under the Purchase Plan.
For the year ended December 31, 2021, the Purchase Plan provided for eligible employees to purchase shares of Class A common stock at a price of 90% of the lesser of: (a) the fair market value of a share of Class A common stock on the first date of the purchase period or (b) the fair market value of a share of Class A common stock on the last date of the purchase period. Stock-based compensation expense for the Purchase Plan was recognized over the vesting period of three months on a straight-line basis. The fair values of the options granted under the Purchase Plan were estimated at the date of grant during the year ended December 31, 2021, based upon the following assumptions, and were as follows:

We have seven industry-based operating segments, which are aggregated into four reportable business segments:
•Financial Services, which consists of the banking and insurance operating segments;
•Health Sciences (previously referred to as Healthcare), which consists of a single operating segment of the same name;
•Products and Resources, which consists of the retail and consumer goods; manufacturing, logistics, energy, and utilities; and travel and hospitality operating segments; and
•Communications, Media and Technology, which consists of a single operating segment of the same name.
Our segments are industry-based, and as such, we report revenue from clients in the segment with which our clients are most closely aligned. Our client partners, account executives and client relationship managers are aligned in accordance with the specific industries they serve. Our CODM evaluates the Company's performance and allocates resources based on segment revenues and operating profit. Segment operating profit is defined as income from operations before unallocated costs. Generally, operating expenses for each operating segment have similar characteristics and are subject to the same factors, pressures and challenges. However, the economic environment and its effects on industries served by the operating segments may affect revenues and operating expenses to differing degrees.
In 2023, we made certain changes to the internal measurement of segment operating profit for the purpose of evaluating segment performance and resource allocation. The primary reason for the change was to reflect a more complete cost of delivery. Specifically, segment operating profit now includes an allocation of both SG&A costs related to our integrated practices and the excess or shortfall of incentive-based compensation for commercial and delivery employees as compared to target, which were previously included in "unallocated costs." We have reported 2023 segment operating profits using the new allocation methodology and have recast the 2022 and 2021 results to conform to the new methodology.
Corporate expenses, expenses related to our NextGen program, a portion of depreciation and amortization and the impact of the settlements of the cash flow hedges are not allocated to individual segments in internal management reports used by the CODM. Accordingly, such expenses are excluded from segment operating profit and are included below as “unallocated costs” and adjusted against our total income from operations. Additionally, we do not disclose assets by segment as a significant portion of the assets is used interchangeably among the segments and the CODM does not review such information.
For revenues by reportable business segment and geographic area see Note 2.

Accounting Policies [Abstract]  
Basis of Presentation And Principles of Consolidation Basis of Presentation, Principles of Consolidation and Use of Estimates. The consolidated financial statements are presented in accordance with GAAP and reflect the consolidated financial position, results of operations, comprehensive income and cash flows of our consolidated subsidiaries for all periods presented. All intercompany balances and transactions have been eliminated in consolidation.
Use Of Estimates The preparation of financial statements requires management to make estimates and assumptions that affect the reported amounts in the consolidated financial statements and accompanying disclosures. We evaluate our estimates on a continuous basis. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances. The actual amounts may vary from the estimates used in the preparation of the accompanying consolidated financial statements.
Cash And Cash Equivalents And Investments
Cash and Cash Equivalents and Investments. Cash and cash equivalents consist of all cash balances, including money market funds, time deposits, certificates of deposits and commercial paper that have a maturity, at the date of purchase, of 90 days or less.
We determine the appropriate classification of our investments in marketable securities at the date of purchase and reevaluate such designation at each balance sheet date. We classify and account for our marketable debt securities as either available-for-sale or held-to-maturity. After consideration of our risk versus reward objectives, as well as our liquidity requirements, we may sell our available-for-sale securities prior to their stated maturities. We classify these marketable securities with maturities at the date of purchase beyond 90 days as short-term investments based on their highly liquid nature and because such marketable securities represent an investment of cash that is available for current operations. Available-for-sale securities are reported at fair value with changes in unrealized gains and losses recorded as a separate component of "Accumulated other comprehensive income (loss)" on the consolidated statements of financial position until realized. We determine the cost of the securities sold based on the specific identification method. Our held-to-maturity investment securities are financial instruments that we have the intent and ability to hold to maturity and we classify these securities with maturities less than one year as short-term investments. Any held-to-maturity investment securities with maturities beyond one year from the balance sheet date are classified as long-term investments. Held-to-maturity securities are reported at amortized cost. Interest and amortization of premiums and discounts for debt securities are included in interest income.

For available-for-sale debt securities, if we do not intend to sell the security or it is not more likely than not that we will be required to sell the security before recovery of our amortized cost, we evaluate qualitative criteria, such as the financial health of and specific prospects for the issuer, to determine whether we do not expect to recover the amortized cost basis of the security. We also evaluate quantitative criteria including determining whether there has been an adverse change in expected future cash flows. If we do not expect to recover the entire amortized cost basis of the security, we consider the security to contain an expected credit loss, and we record the difference between the security’s amortized cost basis and its recoverable amount in earnings as an allowance for credit loss and the difference between the security’s recoverable amount and fair value in other comprehensive income. If we intend to sell the security or it is more likely than not we will be required to sell the security before recovery of its amortized cost basis, the security is considered impaired, and we recognize the entire difference between the security’s amortized cost basis and its fair value in earnings.
On initial recognition and on an ongoing basis, we evaluate our held-to-maturity investment securities for expected credit losses collectively when they share similar risk characteristics or individually, when the risk characteristics are different. The allowance for expected credit losses is determined using our historical loss experience. We monitor the credit ratings of the securities in our portfolio to evaluate the need for any changes to the allowance. An increase or a decrease in the allowance for expected credit losses is recorded through income as a credit loss expense or a reversal thereof. The allowance for expected credit losses is presented as a deduction from the amortized cost. A held-to-maturity investment security is written off when deemed uncollectible.
Short-Term Financial Assets And Liabilities
Financial Assets and Liabilities. Cash and certain cash equivalents, time deposits, trade receivables, accounts payable and other accrued liabilities are short-term in nature and, accordingly, their carrying values approximate fair value.
Property And Equipment
Property and Equipment. Property and equipment are stated at cost, net of accumulated depreciation. Depreciation is calculated on a straight-line basis over the estimated useful lives of the assets. Leasehold improvements are amortized on a straight-line basis over the shorter of the term of the lease or the estimated useful life of the asset. Deposits paid towards acquisition of long-lived assets and the cost of assets not put in use by the balance sheet date are disclosed under the caption "Capital work-in-progress" in Note 6.
Lessee, Leases
Leases. Our lease asset classes primarily consist of operating leases for office space, data centers and IT equipment. At inception of a contract, we determine whether a contract contains a lease, and if a lease is identified, whether it is an operating or finance lease. In determining whether a contract contains a lease we consider whether (1) we have the right to obtain substantially all of the economic benefits from the use of the asset throughout the term of the contract, (2) we have the right to direct how and for what purpose the asset is used throughout the term of the contract and (3) we have the right to operate the asset throughout the term of the contract without the lessor having the right to change the terms of the contract. Some of our lease agreements contain both lease and non-lease components that we account for as a single lease component for all of our lease asset classes.
Our ROU lease assets represent our right to use an underlying asset for the lease term and may include any advance lease payments made and any initial direct costs and exclude lease incentives. Our lease liabilities represent our obligation to make lease payments arising from the terms of the lease. ROU lease assets and lease liabilities are recognized at the commencement of the lease and are calculated using the present value of lease payments over the lease term. Typically, our lease agreements do not provide sufficient detail to determine the rate implicit in the lease. Therefore, we use our estimated country-specific incremental borrowing rate based on information available at the commencement date of the lease to calculate the present value of the lease payments. In estimating our country-specific incremental borrowing rates, we consider market rates of comparable collateralized borrowings for similar terms. Our lease terms may include the option to extend or terminate the lease before the end of the contractual lease term. Our ROU lease assets and lease liabilities include these options when it is reasonably certain that they will be exercised.
A portion of our real estate lease costs is subject to annual changes in the CPI. Changes in CPI subsequent to the lease commencement are treated as variable lease payments and are recognized in the period in which the obligation for those payments is incurred. Other variable lease costs primarily relate to adjustments for common area maintenance, utilities, property tax and lease concessions. These variable costs are recognized in the period in which the obligation is incurred.

We elect not to recognize ROU assets and lease liabilities for short-term leases with a term equal to or less than 12 months. We recognize the lease payments in our income statement on a straight-line basis over the lease term and variable lease payments in the period in which the obligation for those payments is incurred.

Both ROU assets and finance lease assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the related asset group may not be recoverable.
Internal Use Software
Internal Use Software. We capitalize certain costs that are incurred to purchase, develop and implement internal-use software during the application development phase, which primarily include coding, testing and certain data conversion activities. Capitalized costs are amortized on a straight-line basis over the useful life of the software. Costs incurred in performing planning and post-implementation activities are expensed as incurred.
Cloud Computing Arrangements Cloud Computing Arrangements. We defer certain implementation costs that are incurred when implementing cloud computing service or software-as-a-service arrangements, which primarily include efforts associated with configuration and development activities. Once the service is ready for use, deferred costs are expensed over the term of the arrangement and recognized in income from operations.
Software to be Sold Leased or Marketed
Software to be Sold, Leased or Marketed. We capitalize costs incurred after technological feasibility is reached but before software is available for general release to clients, which primarily include coding and testing activities. Once the product is ready for general release, capitalized costs are amortized over the useful life of the software.
Business Combinations
Business Combinations. We account for business combinations using the acquisition method, which requires the identification of the acquirer, the determination of the acquisition date and the allocation of the purchase price paid by the acquirer to the identifiable tangible and intangible assets acquired, the liabilities assumed, including any contingent consideration and any noncontrolling interest in the acquiree at their acquisition date fair values. Goodwill represents the excess of the purchase price over the fair value of net assets acquired, including the amount assigned to identifiable intangible assets. Identifiable intangible assets with finite lives are amortized over their expected useful lives. Acquisition-related costs are expensed in the periods in which the costs are incurred. The results of operations of acquired businesses are included in our consolidated financial statements from the acquisition date.
Equity Method Investments Equity Method Investments. Equity investments that give us the ability to exercise significant influence, but not control, over an investee are accounted for using the equity method of accounting and recorded in the caption "Long-term investments" on our consolidated statements of financial position. Equity method investments are initially recorded at cost. We periodically review the carrying value of our equity method investments to determine if there has been an other-than-temporary decline in the carrying value. The investment balance is increased to reflect contributions and our share of earnings and decreased to reflect our share of losses, distributions and other-than-temporary impairments. Our proportionate share of the net income or loss of the investee is recorded in the caption "Income (loss) from equity method investments" on our consolidated statements of operations.
Long-Lived Assets And Finite-Lived Intangibles
Long-lived Assets and Finite-lived Intangible Assets. We review long-lived assets and certain finite-lived intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset group may not be recoverable. The carrying amount may not be recoverable when the sum of undiscounted expected future cash flows is less than the carrying amount of such asset groups. The impairment loss is determined as the amount by which the carrying amount of the asset group exceeds its fair value. Intangible assets consist primarily of customer relationships and developed technology, which are being amortized on a straight-line basis over their estimated useful lives.
Goodwill And Indefinite-Lived intangibles
Goodwill and Indefinite-lived Intangible Assets. At each acquisition date, we allocate goodwill and intangible assets to our reporting units based on how we expect each reporting unit to benefit from the respective business combination. Our seven industry-based operating segments are our reporting units. We evaluate goodwill and indefinite-lived intangible assets for impairment at least annually, or as circumstances warrant. Goodwill is evaluated at the reporting unit level by comparing the fair value of the reporting unit with its carrying amount including goodwill. An impairment of goodwill exists if the carrying amount of the reporting unit exceeds its fair value. The impairment loss is the amount by which the carrying amount exceeds the reporting unit’s fair value, limited to the total amount of goodwill allocated to that reporting unit. For indefinite-lived intangible assets, if our qualitative assessment indicates that it is more-likely-than-not that an indefinite-lived intangible asset is impaired, we test the assets for impairment by comparing the fair value of such assets to their carrying value. If an impairment is indicated, a write down to the fair value of indefinite-lived intangible asset is recorded.
Stock Repurchase Program Stock Repurchase Program. Under the Board of Directors authorized stock repurchase program, the Company is authorized to repurchase its Class A common stock through open market purchases, including under a 10b5-1 Plan, in accordance with applicable federal securities laws. We account for the repurchased shares as constructively retired. Shares are returned to the status of authorized and unissued shares at the time of repurchase. To reflect share repurchases in the consolidated statements of financial position, we (1) reduce common stock for the par value of the shares, (2) reduce additional paid-in capital for the amount in excess of par during the period in which the shares are repurchased and (3) record any residual amount in excess of available additional paid-in capital as a reduction to retained earnings.
Revenue Recognition
Revenue Recognition. We recognize revenues as we transfer control of deliverables (products, solutions and services) to our clients in an amount reflecting the consideration to which we expect to be entitled. To recognize revenues, we apply the following five step approach: (1) identify the contract with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract, and (5) recognize revenues when a performance obligation is satisfied. We account for a contract when it has approval and commitment from all parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectibility of consideration is probable. We apply judgment in determining the customer’s ability and intention to pay based on a variety of factors including the customer’s historical payment experience.
For performance obligations where control is transferred over time, revenues are recognized based on the extent of progress towards completion of the performance obligation. The selection of the method to measure progress towards completion requires judgment and is based primarily on the nature of the deliverables to be provided.
Revenues related to fixed-price contracts for application development and systems integration services, consulting or other technology services are recognized as the service is performed using the cost-to-cost method, under which the total value of revenues is recognized on the basis of the percentage that each contract’s total labor cost to date bears to the total expected labor costs. Revenues related to fixed-price application maintenance, quality engineering and assurance as well as business process services are recognized based on our right to invoice for services performed for contracts in which the invoicing is representative of the value being delivered. If our invoicing is not consistent with the value delivered, revenues are recognized as the service is performed based on the cost-to-cost method described above. The cost-to-cost method requires estimation of future costs, which is updated as the project progresses to reflect the latest available information. Such estimates and changes in estimates involve the use of judgment. The cumulative impact of any revision in estimates is reflected in the financial reporting period in which the change in estimate becomes known and any anticipated losses on contracts are recognized immediately, where appropriate.

Revenues related to fixed-price hosting and infrastructure and security services are recognized based on our right to invoice for services performed for contracts in which the invoicing is representative of the value being delivered. If our invoicing is not consistent with the value delivered, revenues are recognized on a straight-line basis unless revenues are earned and obligations are fulfilled in a different pattern. The revenue recognition method applied to the types of contracts described above provides the most faithful depiction of performance towards satisfaction of our performance obligations; for example, the cost-to-cost method is used when the value of services provided to the customer is best represented by the costs expended to deliver those services.

Revenues related to our time-and-materials, transaction-based or volume-based contracts are recognized over the period the services are provided either using an output method such as labor hours, or a method that is otherwise consistent with the way in which value is delivered to the customer.

Revenues related to our non-hosted software license arrangements that do not require significant modification or customization of the underlying software are recognized when the software is delivered as control is transferred at a point in time. For software license arrangements that require significant functionality enhancements or modification of the software, revenues for the software license and related services are recognized as the services are performed in accordance with the methods applicable to application development and systems integration services described above. In software hosting arrangements, the rights provided to the customer, such as ownership of a license, contract termination provisions and the feasibility of the client to operate the software, are considered in determining whether the arrangement includes a license or a service. Sales and usage-based fees promised in exchange for licenses of intellectual property are not recognized as revenue until the uncertainty related to the variable amounts is resolved. Revenues related to software maintenance and support are generally recognized on a straight-line basis over the contract period.

Incentive revenues, volume discounts, or any other form of variable consideration is estimated using either the sum of probability weighted amounts in a range of possible consideration amounts (expected value) or the single most likely amount in a range of possible consideration amounts (most likely amount), depending on which method better predicts the amount of consideration to which we may be entitled. We include in the transaction price variable consideration only to the extent it is probable that a significant reversal of revenues recognized will not occur when the uncertainty associated with the variable consideration is resolved. Our estimates of variable consideration and determination of whether and when to include estimated amounts in the transaction price may involve judgment and are based largely on an assessment of our anticipated performance and all information that is reasonably available to us.

Revenues also include the reimbursement of out-of-pocket expenses. Our warranties generally provide a customer with assurance that the related deliverable will function as the parties intended because it complies with agreed-upon specifications and are therefore not considered an additional performance obligation in the contract.

We may enter into arrangements that consist of multiple performance obligations. Such arrangements may include any combination of our deliverables. To the extent a contract includes multiple promised deliverables, we apply judgment to determine whether promised deliverables are capable of being distinct and are distinct in the context of the contract. If these criteria are not met, the promised deliverables are accounted for as a combined performance obligation. For arrangements with multiple distinct performance obligations, we allocate consideration among the performance obligations based on their relative standalone selling price. Standalone selling price is the price at which we would sell a promised good or service separately to the customer. When not directly observable, we typically estimate standalone selling price by using the expected cost plus margin or, in limited circumstances, the residual value approach. We typically establish a standalone selling price range for our deliverables, which is reassessed on a periodic basis or when facts and circumstances change.
We assess the timing of the transfer of goods or services to the customer as compared to the timing of payments to determine whether a significant financing component exists. As a practical expedient, we do not assess the existence of a significant financing component when the difference between payment and transfer of deliverables is a year or less. If the difference in timing arises for reasons other than the provision of finance to either the customer or us, no financing component is deemed to exist. The primary purpose of our invoicing terms is to provide customers with simplified and predictable ways of purchasing our services, not to receive or provide financing from or to customers. We do not consider set up or transition fees paid upfront by our customers to represent a financing component, as such fees are required to encourage customer commitment to the project and protect us from early termination of the contract.

Our contracts may be modified to add, remove or change existing performance obligations. The accounting for modifications to our contracts involves assessing whether the services added to an existing contract are distinct and whether the pricing is at the standalone selling price. Services added that are not distinct are accounted for on a cumulative catch up basis, while those that are distinct are accounted for prospectively, either as a separate contract if the additional services are priced at the standalone selling price, or as a termination of the existing contract and creation of a new contract if not priced at the standalone selling price. Services added to our application development and systems integration service contracts are typically not distinct, while services added to our other contracts, including application maintenance, quality engineering and assurance as well as business process services contracts, are typically distinct.
From time to time, we may enter into arrangements with third party suppliers to resell products or services. In such cases, we evaluate whether we are the principal (i.e., report revenues on a gross basis) or agent (i.e., report revenues on a net basis). In doing so, we evaluate whether we control the good or service before it is transferred to the customer. If we control the good or service before it is transferred to the customer, we are the principal; if not, we are the agent. Determining whether we control the good or service before it is transferred to the customer requires significant judgment.
Trade Accounts Receivable, Contract Assets and Contract Liabilities. We classify our right to consideration in exchange for deliverables as either a receivable or a contract asset. A receivable is a right to consideration that is unconditional (i.e., only the passage of time is required before payment is due). For example, we recognize a receivable for revenues related to our time and materials and transaction or volume-based contracts when earned regardless of whether amounts have been billed. We present such receivables in "Trade accounts receivable, net" in our consolidated statements of financial position at their net estimated realizable value. A contract asset is a right to consideration that is conditional upon factors other than the passage of time. Contract assets are presented in "Other current assets" or "Other noncurrent assets" in our consolidated statements of financial position, based on the expected timing of billing, and primarily relate to unbilled amounts on fixed-price contracts utilizing the cost-to-cost method of revenue recognition. Our contract liabilities, or deferred revenue, consist of advance payments from clients and billings in excess of revenues recognized. We classify deferred revenue as current or noncurrent based on the timing of when we expect to recognize the revenues.
Our contract assets and contract liabilities are reported on a net basis by contract at the end of each reporting period. The difference between the opening and closing balances of our contract assets and contract liabilities primarily results from the timing difference between our performance obligations and the client’s payment. We receive payments from clients based on the terms established in our contracts, which vary from contract to contract.
Allowance for Credit Losses. We calculate expected credit losses for our trade accounts receivable and contract assets. Expected credit losses include losses expected based on known credit issues with specific customers as well as a general expected credit loss allowance based on relevant information, including historical loss rates, current conditions, and reasonable economic forecasts that affect collectibility. We update our allowance for credit losses on a quarterly basis with changes in the allowance recognized in income from operations.
Costs to Fulfill. Recurring operating costs for contracts with customers are recognized as incurred. Certain eligible, nonrecurring costs (i.e., set-up or transition costs) are capitalized when such costs (1) relate directly to the contract, (2) generate or enhance resources of the Company that will be used in satisfying the performance obligation in the future, and (3) are expected to be recovered. These costs are expensed ratably over the estimated life of the customer relationship, including expected contract renewals. In determining the estimated life of the customer relationship, we evaluate the average contract term on a portfolio basis by nature of the services to be provided, and apply judgment in evaluating the rate of technological and industry change. Capitalized amounts are monitored regularly for impairment. Impairment losses are recorded when projected remaining consideration that has not already been recognized as revenue less costs related to the services being provided are not sufficient to recover the carrying amount of the capitalized costs to fulfill. Costs to fulfill are recorded in "Other noncurrent assets" in our consolidated statements of financial position and the amortization expense of costs to fulfill is included in "Cost of revenues" in our consolidated statements of operations.
Accounts Receivable
Trade Accounts Receivable, Contract Assets and Contract Liabilities. We classify our right to consideration in exchange for deliverables as either a receivable or a contract asset. A receivable is a right to consideration that is unconditional (i.e., only the passage of time is required before payment is due). For example, we recognize a receivable for revenues related to our time and materials and transaction or volume-based contracts when earned regardless of whether amounts have been billed. We present such receivables in "Trade accounts receivable, net" in our consolidated statements of financial position at their net estimated realizable value. A contract asset is a right to consideration that is conditional upon factors other than the passage of time. Contract assets are presented in "Other current assets" or "Other noncurrent assets" in our consolidated statements of financial position, based on the expected timing of billing, and primarily relate to unbilled amounts on fixed-price contracts utilizing the cost-to-cost method of revenue recognition. Our contract liabilities, or deferred revenue, consist of advance payments from clients and billings in excess of revenues recognized. We classify deferred revenue as current or noncurrent based on the timing of when we expect to recognize the revenues.
Our contract assets and contract liabilities are reported on a net basis by contract at the end of each reporting period. The difference between the opening and closing balances of our contract assets and contract liabilities primarily results from the timing difference between our performance obligations and the client’s payment. We receive payments from clients based on the terms established in our contracts, which vary from contract to contract.
Allowance for Credit Losses. We calculate expected credit losses for our trade accounts receivable and contract assets. Expected credit losses include losses expected based on known credit issues with specific customers as well as a general expected credit loss allowance based on relevant information, including historical loss rates, current conditions, and reasonable economic forecasts that affect collectibility. We update our allowance for credit losses on a quarterly basis with changes in the allowance recognized in income from operations.
Stock-Based Compensation
Stock-Based Compensation. Stock-based compensation expense for awards of equity instruments to employees and non-employee directors is determined based on the grant date fair value of those awards. We recognize these compensation costs net of an estimated forfeiture rate over the requisite service period of the award. Forfeitures are estimated on the date of grant and revised if actual or expected forfeiture activity differs materially from original estimates. Stock-based compensation expense relating to RSUs and PSUs is recognized as shares vest over the requisite service period. If the minimum performance targets are not met, no compensation cost is recognized and any recognized compensation cost is reversed, except for awards subject to a market condition. The fair value of RSUs and PSUs is determined based on the number of stock units granted and the quoted price of our stock at the date of grant. The fair value of PSUs granted subject to a market condition is determined using a Monte Carlo valuation model.
Foreign Currency
Foreign Currency. The assets and liabilities of our foreign subsidiaries whose functional currency is not the U.S. dollar are translated into U.S. dollars at current exchange rates while revenues and expenses are translated at average monthly exchange rates. The resulting translation adjustments are recorded in the caption "Accumulated other comprehensive income (loss)" on the consolidated statements of financial position.
Foreign currency transactions and balances are those that are denominated in a currency other than the entity’s functional currency. An entity's functional currency is the currency of the primary economic environment in which it operates. The U.S. dollar is the functional currency for some of our foreign subsidiaries. For these subsidiaries, transactions and balances denominated in the local currency are foreign currency transactions. Foreign currency transactions and balances related to non-monetary assets and liabilities are remeasured to the functional currency of the entity at historical exchange rates while monetary assets and liabilities are remeasured to the functional currency of the entity at current exchange rates. Foreign currency exchange gains or losses from remeasurement are included in the caption "Foreign currency exchange gain (losses), net" on our consolidated statements of operations together with gains or losses on our undesignated foreign currency hedges.
Derivative Financial Instruments
Derivative Financial Instruments. Derivative financial instruments are recorded on our consolidated statements of financial position as either an asset or liability measured at its fair value as of the reporting date. Our derivative financial instruments consist primarily of foreign exchange forward and option contracts. For derivative financial instruments to qualify for hedge accounting, the following criteria must be met: (1) the hedging instrument must be designated as a hedge; (2) the hedged exposure must be specifically identifiable and must expose us to risk; and (3) it must be expected that a change in fair value of the hedging instrument and an opposite change in the fair value of the hedged exposure will have a high degree of correlation. Changes in our derivatives’ fair values are recognized in net income unless specific hedge accounting and documentation criteria are met (i.e., the instruments are designated and accounted for as hedges). We record the effective portion of the unrealized gains and losses on our derivative financial instruments that are designated as cash flow hedges in the caption "Accumulated other comprehensive income (loss)" in the consolidated statements of financial position. Any ineffectiveness or excluded portion of a designated cash flow hedge is recognized in net income. Upon occurrence of the hedged transaction, the gains and losses on the derivative are recognized in net income.
Income Taxes
Income Taxes. We provide for income taxes utilizing the asset and liability method of accounting. Under this method, deferred income taxes are recorded to reflect the tax consequences in future years of differences between the tax basis of assets and liabilities and their financial reporting amounts at each balance sheet date, based on enacted tax laws and statutory tax rates applicable to the periods in which the differences are expected to affect taxable income. If it is determined that it is more likely than not that future tax benefits associated with a deferred income tax asset will not be realized, a valuation allowance is provided. The effect of a change in tax rates on deferred income tax assets and liabilities is recognized in the provision for income taxes in the period that includes the enactment date.
Our provision for income taxes also includes the impact of provisions established for uncertain income tax positions, as well as any related penalties and interest. We adjust these reserves in light of changing facts and circumstances, such as the closing of a tax audit or the expiration of the applicable statute of limitations. To the extent that the final outcome of these matters differs from the amounts recorded, such differences will impact the provision for income taxes in the period in which such determination is made.
Earnings Per Share, Or EPS
Earnings Per Share. Basic EPS is computed by dividing earnings available to common stockholders by the weighted-average number of common shares outstanding for the period. Diluted EPS includes all potential dilutive common stock in the weighted average shares outstanding. We excluded less than 1 million of anti-dilutive shares in each of 2023, 2022 and 2021 from our diluted EPS calculation. We include PSUs in the dilutive common shares when they become contingently issuable per the authoritative guidance and exclude them when they are not contingently issuable.

Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures

Annual period starting in 2024 and interim periods starting in 2025


Retrospective basis

The new standard requires enhanced segment disclosures but does not change the definition of a segment for the guidance for determining a reportable segment. The amendments require disclosure of significant segment expenses regularly provided to the CODM included within segment operating profit or loss and a description of how the CODM utilizes segment operating profit or loss to assess segment performance and allocating resources. The new standard also allows companies to disclose multiple measures of segment profit or loss if those measures are used to allocate resources.
The Company is currently evaluating the impact of the new standard on its related disclosures.

Income Taxes (Topic 740): Improvements to Income Tax Disclosures

Annual period starting in 2025


Prospective basis although retrospective application is permitted

The new standard requires enhanced income tax disclosures primarily related to the rate reconciliation and income taxes paid information.
The Company is currently evaluating the impact of the new standard on its related disclosures.
Costs Associated with Exit or Disposal Activity or Restructuring
Restructuring Charges. Restructuring charges principally consist of severance and related separation costs, facility exit costs and other related third-party costs necessary to execute the restructuring program. The Company accrues for severance and other related separation costs when it is probable that termination benefits will be paid and the amount is reasonably
estimable. Recognition of employee severance and other separation costs is also dependent on requirements established by severance policy, statutory laws, or historical experience. Facility exit costs generally reflect the accelerated lease expense for right-of-use assets, expected lease termination costs, and asset impairments in connection with closure of certain sites, net of gains on exit-related disposals.
Restructuring costs are recorded in “Restructuring charges” in the consolidated statements of operations. The restructuring liability related to accrued employee separation costs is included in "Accrued expenses and other current liabilities" in the consolidated statements of financial position. At the end of each reporting period, the Company evaluates the remaining accrued balances to ensure these balances are properly stated.

Disaggregation of Revenue
Disaggregation of Revenues

The tables below present disaggregated revenues from contracts with clients by client location, service line and contract type for each of our reportable business segments. We believe this disaggregation best depicts how the nature, amount, timing and uncertainty of our revenues and cash flows are affected by industry, market and other economic factors. Our consulting and technology services include consulting, application development, systems integration, quality engineering and assurance services as well as software solutions and related services while our outsourcing services include application maintenance, infrastructure and security as well as business process services. Revenues are attributed to geographic regions based upon client location, which is the client's billing address. Substantially all revenues in our North America region relate to clients in the United States.
