Accounting Policies [Abstract]
Principles of Consolidation	The consolidated financial statements include the accounts of Fiserv, Inc. and its subsidiaries in which the Company holds a majority controlling financial interest. All intercompany transactions and balances between the Company and its subsidiaries have been eliminated in consolidation. Control is typically established when ownership and voting interests in an entity are greater than 50%. Investments in which the Company has significant influence but not control are accounted for using the equity method of accounting, for which the Company’s share of net income or loss is reported within income from investments in unconsolidated affiliates, and the related tax expense or benefit is reported within the income tax provision in the consolidated statements of income. Significant influence over an affiliate’s operations generally coincides with an ownership interest of between 20% and 50%; however, for partnerships and limited liability companies, an ownership interest of between 3% and 50% or board of director representation may also constitute significant influence. The Company maintains a majority controlling financial interest in certain entities, mostly related to consolidated merchant alliances (see Note 19). Noncontrolling interests represent the minority shareholders’ share of the net income or loss and equity in consolidated subsidiaries. The Company’s noncontrolling interests presented in the consolidated statements of income include net income attributable to noncontrolling interests and redeemable noncontrolling interests. Noncontrolling interests are presented as a component of equity in the consolidated balance sheets. Noncontrolling interests that are redeemable upon the occurrence of an event that is not solely within the Company’s control are presented outside of equity and are carried at their estimated redemption value if it exceeds the initial carrying value of the redeemable interest (see Note 12).
Use of Estimates	The preparation of financial statements in conformity with accounting principles generally accepted in the United States (“U.S.”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ materially from those estimates.
Revenue Recognition	The Company generates revenue from the delivery of processing, service and product solutions. Revenue is measured based on consideration specified in a contract with a customer, and excludes any amounts collected on behalf of third parties. The Company recognizes revenue when it satisfies a performance obligation by transferring control over a product or service to a customer which may be at a point in time or over time. Additional information regarding the Company’s revenue recognition policies is included in Note 3 to the consolidated financial statements. Significant Accounting Policy ASC 606 outlines a single comprehensive model to use in accounting for revenue arising from contracts with customers. The core principle, involving a five-step process, of the revenue model is that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Revenue is measured based on consideration specified in a contract with a customer, and excludes any amounts collected on behalf of third parties. Taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction, that are collected by the Company from a customer, are excluded from revenue. Shipping and handling activities associated with outbound freight after control over a product has transferred to a customer are accounted for as a fulfillment activity and recognized as revenue at the point in time at which control of the goods transfers to the customer. As a practical expedient, the Company does not adjust the transaction price for the effects of a significant financing component if, at contract inception, the period between customer payment and the transfer of goods or services is expected to be one year or less. Nature of Goods and Services The Company’s operations are comprised of the Acceptance segment, the Fintech segment and the Payments segment (see Note 20). The following is a description of principal activities from which the Company generates its revenue. Contracts with customers are evaluated on a contract-by-contract basis as contracts may include multiple types of goods and services as described below. Processing and Services Processing and services revenue is generated from account- and transaction-based fees for merchant transaction processing and acquiring, electronic billing and payment services, electronic funds transfer and debit/credit processing services; consulting and professional services; and software maintenance for ongoing client support. The Company recognizes processing and services revenue in the period in which the specific service is performed unless they are not deemed distinct from other goods or services in which revenue would then be recognized as control is transferred of the combined goods and services. The Company’s arrangements for processing and services typically consist of an obligation to provide specific services to its customers on a when and if needed basis (a stand-ready obligation) and revenue is recognized from the satisfaction of the performance obligations in the amount billable to the customer. These services are typically provided under a fixed or declining (tier-based) price per unit based on volume of service; however, pricing for services may also be based on minimum monthly usage fees. Fees for the Company’s processing and services arrangements are typically billed and paid on a monthly basis. Product Product revenue is generated from print and card production, software license, and hardware (primarily POS device) sales. For software license agreements that are distinct, the Company recognizes software license revenue upon delivery, assuming a contract is deemed to exist. Revenue for arrangements with customers that include significant customization, modification or production of software such that the software is not distinct is typically recognized over time based upon efforts expended, such as labor hours, to measure progress towards completion. For arrangements involving hosted licensed software for the customer, a software element is considered present to the extent the customer has the contractual right to take possession of the software at any time during the hosting period without significant penalty and it is feasible for the customer to either operate the software on their own hardware or contract with another vendor to host the software. In certain instances, the Company may offer extended payment terms beyond one year. To the extent a significant financing component exists, it is calculated as the difference between the promised consideration and the present value of the software license fees utilizing a discount rate reflective of a separate financing transaction, and is recognized as interest income over the extended payment period. The cash selling price of the software license fee is recognized as revenue at the point in time when the software is transferred to the customer. The Company sells or leases hardware (POS devices) and other peripherals as part of its contracts with customers. Hardware typically consists of POS terminals or Clover® devices. The Company does not manufacture hardware; rather, it purchases hardware from third-party vendors and holds such hardware in inventory until purchased by a customer. The Company accounts for sales of hardware as a separate performance obligation and recognizes the revenue at its standalone selling price when the customer obtains control of the hardware. Significant Judgments in Application of the Guidance The Company uses the following methods, inputs and assumptions in determining amounts of revenue to recognize: Identification of Performance Obligations To identify its performance obligations, the Company considers all of the goods or services promised in the contract regardless of whether they are explicitly stated or are implied by customary business practices. For multi-element arrangements, the Company accounts for individual goods or services as a separate performance obligation if they are distinct, the good or service is separately identifiable from other items in the arrangement and if a customer can benefit from it on its own or with other resources that are readily available to the customer. If these criteria are not met, the promised goods or services are accounted for as a combined performance obligation. Determining whether goods or services are distinct performance obligations that should be accounted for separately may require significant judgment. Technology or service components from third parties are frequently embedded in or combined with the Company’s applications or service offerings. Whether the Company recognizes revenue based on the gross amount billed to a customer or the net amount retained involves judgment that depends on the relevant facts and circumstances, including the level of contractual responsibilities and obligations for delivering solutions to end customers, to determine whether control of goods and services is obtained prior to their transfer to a customer. Determination of Transaction Price The transaction price is determined based on the consideration to which the Company will be entitled in exchange for transferring products or services to the customer. The Company includes any fixed charges within its contracts as part of the total transaction price. To the extent that variable consideration is not constrained, the Company includes an estimate of the variable amount, as appropriate, within the total transaction price and updates its assumptions over the duration of the contract. Assessment of Estimates of Variable Consideration Many of the Company’s contracts with customers contain some component of variable consideration; however, the constraint will generally not result in a reduction in the estimated transaction price for most forms of variable consideration. The Company may constrain the estimated transaction price in the event of a high degree of uncertainty as to the final consideration amount owed because of an extended length of time over which fees may be adjusted. Allocation of Transaction Price The transaction price (including any discounts or rebates) is allocated between distinct goods and services in a multi-element arrangement based on their relative standalone selling prices. The standalone selling prices are determined based on the prices at which the Company separately sells each good or service. For items that are not sold separately, the Company estimates the standalone selling prices using available information such as market conditions and internally approved pricing guidelines. Judgment may be required to determine standalone selling prices for each performance obligation and whether it depicts the amount the Company expects to receive in exchange for the related good or service. Contract Modifications Contract modifications occur when the Company and its customers agree to modify existing customer contracts to change the scope or price (or both) of the contract or when a customer terminates some, or all, of the existing services provided by the Company. When a contract modification occurs, it requires the Company to exercise judgment to determine if the modification should be accounted for as (i) a separate contract, (ii) the termination of the original contract and creation of a new contract, or (iii) a cumulative catch up adjustment to the original contract. Further, contract modifications require the identification and evaluation of the performance obligations of the modified contract, including the allocation of consideration to the remaining performance obligations and the period of revenue recognition for each identified performance obligation. Contract assets, reported within other long-term assets in the consolidated balance sheets, primarily result from revenue being recognized where payment is contingent upon the transfer of services to a customer over the contractual period. Contract liabilities primarily relate to advance consideration received from customers (deferred revenue) for which transfer of control occurs, and therefore revenue is recognized, as services are provided. Contract balances are reported in a net contract asset or liability position on a contract-by-contract basis at the end of each reporting period. The Company applies the optional exemption under ASC 606 and does not disclose information about remaining performance obligations for account- and transaction-based processing fees that qualify for recognition under the as-invoiced practical expedient. These multi-year contracts contain variable consideration for stand-ready performance obligations for which the exact quantity and mix of transactions to be processed are contingent upon the customer’s request. The Company also applies the optional exemptions under ASC 606 and does not disclose information for variable consideration that is a sales-based or usage-based royalty promised in exchange for a license of intellectual property or that is allocated entirely to a wholly unsatisfied performance obligation or to a wholly unsatisfied promise to transfer a distinct good or service in a series. The amounts disclosed above as remaining performance obligations consist primarily of fixed or monthly minimum processing fees and maintenance fees under contracts with an original expected duration of greater than one year. Contract Costs The Company incurs incremental costs to obtain a contract as well as costs to fulfill contracts with customers that are expected to be recovered. These costs consist of sales commissions incurred only if a contract is obtained, and customer conversion or implementation related costs.Capitalized contract costs are amortized based on the transfer of goods or services to which the asset relates. The amortization period also considers expected customer lives and whether the asset relates to goods or services transferred under a specific anticipated contract. The amortization of capitalized sales commissions is included in selling, general and administrative expenses and amortization of capitalized conversion or implementation costs within cost of processing and services.
Cash and Cash Equivalents	Cash and cash equivalents consist of cash and investments with original maturities of 90 days or less and are stated at cost in the consolidated balance sheets, which approximates market value. Cash and cash equivalents that were restricted from use due to regulatory or other requirements are included in other long-term assets in the consolidated balance sheets. Cash and cash equivalents held on behalf of merchants and other payees are included in settlement assets in the consolidated balance sheets.
Allowance for Doubtful Accounts	The Company analyzes the collectability of trade accounts receivable by considering historical bad debts, client creditworthiness, current economic trends, changes in client payment terms and collection trends when evaluating the adequacy of the allowance for doubtful accounts. Any change in the assumptions used in analyzing a specific account receivable may result in an additional allowance for doubtful accounts being recognized in the period in which the change occurs.
Leases, Company as Lessor	The Company maintains certain leasing receivables associated with its POS terminal leasing businesses. Leasing receivables are included in prepaid expenses and other current assets and other long-term assets in the consolidated balance sheets. Interest income on the Company’s leasing receivables is recognized using the effective interest method, and is included within product revenue in the consolidated statements of income. Initial direct costs incurred to obtain operating leases and other sales-type leases, in which the fair value of the underlying asset is equal to its carrying amount at the lease commencement date, are deferred and recognized over the lease term. Initial direct costs to obtain a sales-type lease are expensed as incurred if the fair value of the underlying asset is different from its carrying amount at the lease commencement date. Additional information regarding the Company’s lease policies is included in Note 10 to the consolidated financial statements.The Company owns certain POS terminal equipment which it leases to merchants. Leases are classified as operating or sales-type leases based on factors such as the lease term, lease payments, and the economic life, fair value and estimated residual value of the asset. The terms of the leases typically range from one month to five years. For operating leases, the minimum lease payments received are recognized as lease income on a straight-line basis over the lease term and the leased asset is included in property and equipment, net in the consolidated balance sheets and depreciated over its estimated useful life. For sales-type leases, selling profit is recognized at the commencement date of the lease to the extent the fair value of the underlying asset is different from its carrying amount. Selling profit is directly impacted by the Company’s estimate of the amount to be derived from the residual value of the asset at the end of the lease term. The residual value of the asset is computed using various assumptions, including the expected value of the underlying asset at the end of the lease term. Unearned income is recognized as interest income over the lease term. For sales-type leases, the Company derecognizes the carrying amount of the underlying leased asset and recognizes a net investment in the leased asset in the consolidated balance sheets. The net investment in a leased asset is computed based on the present value of the minimum lease payments not yet received and the present value of the residual value of the asset.
Prepaid Expenses and Other Current Assets	Prepaid expenses represent advance payments for goods and services to be consumed in the future, such as maintenance, postage and insurance, and totaled $431 million and $410 million at December 31, 2022 and 2021, respectively.The Company offers merchants advance access to capital through its Clover Capital cash advance program. Under this program, merchants sell fixed amounts of their future credit card receivables to the Company in exchange for an up-front purchase price payment.
Settlement Assets and Obligations	Settlement assets and obligations result from timing differences between collection and fulfillment of payment transactions and collateral amounts held to manage merchant credit risk, primarily associated with the Company’s merchant acquiring services. Settlement assets represent cash received or amounts receivable from agents, payment networks, bank partners, merchants or direct consumers. Settlement obligations represent amounts payable to merchants and payees. Certain merchant settlement assets (included within settlement receivables) that relate to settlement obligations are held by partner banks to which the Company does not have legal ownership, but which the Company has the right to use, to satisfy the related settlement obligations. The Company records settlement obligations for amounts payable to merchants and for outstanding payment instruments issued to payees that have not yet been presented for settlement. Additional information regarding the Company’s settlement assets and obligations is included in Note 5 to the consolidated financial statements.
Allowance for Merchant Credit Losses	With respect to the Company’s merchant acquiring business, the Company’s merchant customers have the legal obligation to refund any charges properly reversed by the cardholder. However, in the event the Company is not able to collect the refunded amounts from the merchants, the Company may be liable for the reversed charges. The Company’s risk in this area primarily relates to situations where a cardholder has purchased goods or services to be delivered in the future. The Company requires cash deposits, guarantees, letters of credit or other types of collateral from certain merchants to mitigate this risk. Collateral held by the Company, or held by partner banks for the Company’s benefit, is classified within settlement assets and the obligation to repay the collateral is classified within settlement obligations in the consolidated balance sheets. The Company also utilizes a number of systems and procedures to manage merchant credit risk. Despite these efforts, the Company experiences losses due to merchant defaults. The aggregate merchant credit loss expense, recognized by the Company within cost of processing and services in the consolidated statements of income, was $62 million, $41 million and $113 million for the years ended December 31, 2022, 2021 and 2020, respectively. The amount of collateral available to the Company was $1.5 billion and $2.2 billion at December 31, 2022 and 2021, respectively. The Company maintains an allowance for merchant credit losses that are expected to exceed the amount of merchant collateral. The allowance includes estimated losses from anticipated chargebacks and fraud events that have been incurred on merchants’ payment transactions that have been processed but not yet reported to the Company, which is recorded within accounts payable and accrued expenses in the consolidated balance sheets, as well as estimated losses on refunded amounts to cardholders that have not yet been collected from the merchants, which is recorded within prepaid expenses and other current assets in the consolidated balance sheets. The allowance is based primarily on the Company’s historical experience of credit losses and other factors such as changes in economic conditions or increases in merchant fraud.
Property and Equipment	Property and equipment is reported at cost. Depreciation of property and equipment is computed primarily using the straight-line method over the shorter of the estimated useful life of the asset or the leasehold period, if applicable.
Intangible Assets	Customer related intangible assets represent customer contracts and relationships obtained as part of acquired businesses and are amortized using an accelerated amortization method which corresponds with the customer attrition rates used in the initial valuation of the intangibles over their estimated useful lives, generally ten to twenty years. Acquired software and technology represents software and technology intangible assets obtained as part of acquired businesses and is amortized using the straight-line method over their estimated useful lives, generally four to ten years. Trade names are amortized using the straight-line method over their estimated useful lives, generally eight to twenty years. Non-compete agreements are amortized using the straight-line method over their estimated useful lives, generally four to five years. Purchased software represents software licenses purchased from third parties and is amortized using the straight-line method over their estimated useful lives, generally five years. The Company continually develops, maintains and enhances its products and systems. Product development expenditures represented approximately 7%, 7% and 6% of the Company’s total revenue for the years ended December 31, 2022, 2021 and 2020, respectively. Research and development costs incurred prior to the establishment of technological feasibility are expensed as incurred. Routine maintenance of software products, design costs and other development costs incurred prior to the establishment of a product’s technological feasibility are also expensed as incurred. Costs are capitalized commencing when the technological feasibility of the software has been established. Capitalized software development costs represent the capitalization of certain costs incurred to develop new software or to enhance existing software which is marketed externally or utilized by the Company to process client transactions. Capitalized software development costs are amortized using the straight-line method over their estimated useful lives, generally five years. The Company may, at its discretion, negotiate to pay an independent sales organization (“ISO”) an agreed-upon up-front amount in exchange for the ISO’s surrender of its right to receive commission payments from the Company related to future transactions of merchants referred by the ISO (“residual buyout”). The amount that the Company pays for these residual buyouts is capitalized and subsequently amortized using the straight-line method over the expected life of the merchant portfolios, generally five to nine years. The Company may also obtain residual buyouts as part of acquired businesses. Additional information regarding the Company’s identifiable intangible assets is included in Note 6 to the consolidated financial statements.
Goodwill	Goodwill represents the excess of purchase price over the fair value of identifiable assets acquired and liabilities assumed in a business combination. The Company evaluates goodwill for impairment on an annual basis, or more frequently if circumstances indicate possible impairment. Goodwill is tested for impairment at a reporting unit level, which is one level below the Company’s reportable segments. When assessing goodwill for impairment, the Company considers (i) the prior year’s amount of excess fair value over the carrying value of each reporting unit, (ii) the period of time since a reporting unit’s last quantitative test, (iii) the extent a reorganization or disposition changes the composition of one or more of the reporting units and (iv) other factors to determine whether or not to first perform a qualitative test. When performing a qualitative test, the Company assesses numerous factors to determine whether it is more likely than not that the fair value of its reporting units is less than their respective carrying values. Examples of qualitative factors that the Company assesses include its share price, its financial performance, market and competitive factors in its industry and other events specific to its reporting units. If the Company concludes that it is more likely than not that the fair value of a reporting unit is less than its carrying value, the Company performs a quantitative impairment test by comparing reporting unit carrying values to estimated fair values. The Company elected to perform a quantitative test for certain reporting units, including those that changed in composition or where the prior year’s amount of excess fair value over carrying value was of a lower magnitude, and tested the remainder of its reporting units using a qualitative approach. The Company’s most recent annual impairment assessment of its reporting units in the fourth quarter of 2022 determined that its goodwill was not impaired as the estimated fair values exceeded the carrying values. However, it is reasonably possible that future developments related to the interest or currency exchange rate environments; a shift in strategic initiatives; a deterioration in financial performance or in the success of merchant alliances and relationships within a particular reporting unit; or significant changes in the composition of, or assumptions used in, the quantitative test on certain of the Company’s reporting units (such as an increase in risk-adjusted discount rates) could have a future material impact on one or more of the estimates and assumptions used to evaluate goodwill impairment. There is no accumulated goodwill impairment for the Company through December 31, 2022. Additional information regarding the Company’s goodwill is included in Note 7 to the consolidated financial statements.
Asset Impairment	The Company reviews property and equipment, lease right-of-use (“ROU”) assets, intangible assets and its investments in unconsolidated affiliates for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. The Company reviews capitalized software development costs for impairment at each reporting date. Recoverability of property and equipment, lease ROU assets, capitalized software development costs and other intangible assets is assessed by comparing the carrying amount of the asset to either the undiscounted future cash flows expected to be generated by the asset or the net realizable value of the asset, depending on the type of asset. The Company assesses lease ROU assets that are exited in advance of the non-cancellable lease terms by comparing the carrying values of the lease ROU assets to the discounted cash flows from estimated sublease payments. The Company’s investments in unconsolidated affiliates are assessed by comparing the carrying amount of the investments to their estimated fair values and are impaired if any decline in fair value is determined to be other than temporary. Measurement of any impairment loss is based on estimated fair value.
Fair Value Measurements	The Company applies fair value accounting for all assets and liabilities that are recognized or disclosed at fair value in its consolidated financial statements on a recurring basis. Fair value represents the amount that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities, the Company uses the hierarchy prescribed in Accounting Standards Codification (“ASC”) 820, Fair Value Measurements (“ASC Topic 820”), and considers the principal or most advantageous market and the market-based risk measurements or assumptions that market participants would use in pricing the asset or liability. The three levels in the hierarchy are as follows: •Level 1 – Quoted prices (unadjusted) for identical assets or liabilities in active markets that are accessible as of the measurement date. •Level 2 – Inputs other than quoted prices within Level 1 that are observable either directly or indirectly, including but not limited to quoted prices in markets that are not active, quoted prices in active markets for similar assets or liabilities and observable inputs other than quoted prices such as interest rates or yield curves. •Level 3 – Unobservable inputs reflecting management’s judgments about the assumptions that market participants would use in pricing the asset or liability, including assumptions about risk. Additional information regarding the Company’s fair value measurements is included in Note 9 to the consolidated financial statements. The fair values of cash equivalents, trade accounts receivable, settlement assets and obligations, accounts payable, and client deposits approximate their respective carrying values due to the short period of time to maturity. The Company maintains forward exchange contracts, designated as cash flow hedges, to hedge foreign currency exposure. The Company also maintains cross-currency rate swap contracts, designated as net investment hedges, to hedge a portion of its net investment in certain subsidiaries whose functional currencies are the Euro. These derivative instruments are measured on a recurring basis based on foreign currency spot rates and forwards quoted by banks and foreign currency dealers and are marked to market each period (see Note 13). Contingent consideration related to certain of the Company’s acquisitions (see Note 4) is estimated using the present value of a probability-weighted assessment approach based on the likelihood of achieving the earn-out criteria. The fair value of the Company’s contingent liability for current expected credit losses associated with its debt guarantees, as further described below, is estimated based on assumptions of future risk of default and the corresponding level of credit losses at the time of default.
Foreign Currency	The U.S. dollar is the functional currency of the Company’s U.S.-based businesses and certain foreign-based businesses. Where the functional currency differs from the U.S. dollar, assets and liabilities are translated into U.S. dollars at the exchange rates in effect at the balance sheet date. Revenue and expenses are translated at the average exchange rates during the reporting period. Gains and losses from foreign currency translation are recorded as a separate component of accumulated other comprehensive loss. Gains and losses from foreign currency transactions are included in determining net income for the reporting period. Financial statements of subsidiaries located in highly inflationary economies outside of the U.S. are remeasured into U.S. dollars, and the foreign currency gains and losses from the remeasurement of monetary assets and liabilities are reflected in the consolidated statements of income, rather than in shareholders’ equity. The remeasurement of monetary assets and liabilities resulted in foreign currency exchange losses of $52 million and $5 million during the years ended December 31, 2022 and 2021, respectively, primarily related to Argentina. Foreign currency exchange losses resulting from the remeasurement of monetary assets and liabilities were nominal during the year ended December 31, 2020. To reduce exposure to changes in the value of the Company’s net investments in certain of its foreign currency-denominated subsidiaries due to changes in foreign currency exchange rates, the Company uses fixed-to-fixed cross-currency rate swap contracts and foreign currency-denominated debt as economic hedges of its net investments in such foreign currency-denominated subsidiaries (see Note 13). Accordingly, foreign currency transaction gains or losses on the qualifying net investment hedge instruments are recorded as foreign currency translation, net of tax, within other comprehensive income (loss) in the consolidated statements of comprehensive income and will remain in accumulated other comprehensive loss within the consolidated balance sheets until the sale or complete liquidation of the underlying foreign subsidiaries.
Derivatives	Derivatives are entered into for periods consistent with related underlying exposures and are recorded in the consolidated balance sheets as either an asset or liability measured at fair value. If the derivative is designated as a cash flow hedge, changes in the fair value of the derivative are recorded as a component of accumulated other comprehensive loss and recognized in the consolidated statements of income when the hedged item affects earnings. If the derivative is designated as a net investment hedge, changes in the fair value of the derivative, net of tax, are recorded in the foreign currency translation component of other comprehensive income (loss) until the sale or complete liquidation of the underlying net investment. If the derivative is designated as a fair value hedge, changes in the fair value of the derivative are recorded in the same line item as the changes in the fair value of the hedged item and recognized in the consolidated statements of income. To the extent a derivative is not designated as a hedge, changes in fair value are recognized in the consolidated statements of income. The Company’s policy is to enter into derivatives with creditworthy institutions and not to enter into such derivatives for speculative purposes.
Employee Benefit Plans	The Company maintains frozen defined benefit pension plans covering certain employees in Europe and the U.S. The Company records actuarial gains/losses and prior service cost in the consolidated balance sheets and recognizes changes in these amounts during the year in which changes occur through other comprehensive income (loss). The Company uses various assumptions when computing amounts relating to its defined benefit pension plan obligations and their associated expenses (including the discount rate and the expected rate of return on plan assets). Additional information regarding the Company’s employee benefit plans is included in Note 14 to the consolidated financial statements.
Cost of Processing, Services, and Product	Cost of processing and services consists of costs directly associated with providing services to clients and includes the following: personnel; equipment and data communication; infrastructure costs, including costs to maintain software applications; client support; certain depreciation and amortization; and other operating expenses. Cost of product consists of costs directly associated with the products sold and includes the following: costs of materials and postage; software development; hardware costs (primarily POS devices); personnel; infrastructure costs; certain depreciation and amortization; and other costs directly associated with product revenue.
Selling, General and Administrative Expenses	Selling, general and administrative expenses primarily consist of: salaries, wages, commissions and related expenses paid to sales personnel, administrative employees and management; third-party commissions; advertising and promotional costs; certain depreciation and amortization; and other selling and administrative expenses.
Interest Expense, Net	Interest expense, net consists of interest expense primarily associated with the Company’s outstanding borrowings and finance lease obligations, as well as interest income primarily associated with the Company’s investment securities.
Income Taxes	Deferred tax assets and liabilities are recognized for the expected future tax consequences attributable to differences between financial statement carrying amounts of existing assets and liabilities and their respective tax basis, and net operating loss and tax credit carry-forwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. A valuation allowance is recorded against deferred tax assets if it is more likely than not that some portion or all of the deferred tax assets will not be realized. Liabilities are established for unrecognized tax benefits, attributable to differences between a tax position taken or expected to be taken in a tax return and the benefit recognized in the financial statements. In establishing a liability for an unrecognized tax benefit, assumptions are made in determining whether, and the extent to which, a tax position will be sustained. A tax position is recognized only when it is more likely than not to be sustained upon examination by the relevant taxing authority, based on its technical merits. The amount of tax benefit recognized reflects the largest benefit the Company believes is more likely than not to be realized upon ultimate settlement. As additional information becomes available, the liability for unrecognized tax benefits is reevaluated and adjusted, as appropriate. Tax benefits ultimately realized can differ from amounts previously recognized due to uncertainties, with any such differences generally impacting the provision for income tax.
Net Income Per Share	Net income per share attributable to Fiserv, Inc. in each year is calculated using actual, unrounded amounts. Basic net income per share is computed by dividing net income attributable to Fiserv, Inc. by the weighted-average number of common shares outstanding during the year. Diluted net income per share is computed by dividing net income attributable to Fiserv, Inc. by the weighted-average number of common shares and common stock equivalents outstanding during the year. Common stock equivalents consist of outstanding stock options, unvested restricted stock units and unvested restricted stock awards, and are computed using the treasury stock method.
Recently Adopted Accounting Pronouncements and Recently Issued Accounting Pronouncements	Recently Adopted Accounting Pronouncements In 2021, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2021-10, Government Assistance (Topic 832) (“ASU 2021-10”), which requires that an entity provide certain disclosures in its annual financial statements about transactions with a government that are accounted for by applying a grant or contribution accounting model by analogy. ASU 2021-10 is effective for all business entities for annual periods beginning after December 15, 2021 and may be applied either prospectively or retrospectively to the transactions reflected in the financial statements at the date of initial application. The Company adopted ASU 2021-10, with prospective application of the additional disclosures to the transactions reflected in its consolidated financial statements, for the year ending December 31, 2022. The adoption was not material and therefore did not have an impact on the Company’s financial statement disclosures. In 2021, the FASB issued ASU No. 2021-08, Accounting for Contract Assets and Contract Liabilities from Contracts with Customers (“ASU 2021-08”), which requires that an entity recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with ASC Topic 606, Revenue from Contracts with Customers (“ASC 606”). Generally, this should result in recognition and measurement of contract assets and contract liabilities at carryover value consistent with how they were recognized and measured in the acquired company’s financial statements, providing consistent recognition and enhanced comparability with revenue contracts with customers not acquired in a business combination. Prior to adoption of ASU 2021-08, an acquirer generally recognized contract assets and contract liabilities acquired in a business combination at fair value on the acquisition date. For public entities, ASU 2021-08 is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. Entities are required to apply a prospective transition approach upon adoption, unless early adoption occurs in an interim period. The Company adopted ASU 2021-08 effective January 1, 2022, with prospective application to business combinations occurring after adoption, and the adoption did not have a material impact on the Company’s consolidated financial statements. In 2021, the FASB issued ASU No. 2021-05, Leases (Topic 842): Lessors – Certain Leases with Variable Lease Payments (“ASU 2021-05”), which amends the lease classification requirements for lessors with certain leases containing variable payments. A lessor is to classify and account for a lease with variable lease payments that do not depend on an index or a rate as an operating lease if the lease would have been classified as a sales-type lease or a direct financing lease and the lessor would have otherwise recognized a day-one loss. For public entities, ASU 2021-05 is effective for fiscal years beginning after December 15, 2021, including interim periods within those fiscal years, with early adoption permitted.

The Company adopted ASU 2021-05 effective January 1, 2022, with prospective application to leases commencing or modified thereafter, and the adoption did not have a material impact on its consolidated financial statements. Recently Issued Accounting Pronouncements In 2022, the FASB issued ASU No. 2022-03, Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions (“ASU 2022-03”), which clarifies the guidance in ASC Topic 820, Fair Value Measurement, when measuring the fair value of an equity security subject to contractual restrictions that prohibit the sale of an equity security and introduces new disclosure requirements for equity securities subject to contractual sale restrictions that are measured at fair value in accordance with ASC Topic 820. For public entities, ASU 2022-03 is effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. The provisions within ASU 2022-03 are to be applied prospectively with any adjustments from the adoption recognized in earnings and disclosed on the date of adoption. The Company is currently assessing the impact the adoption of ASU 2022-03 will have on its consolidated financial statements and disclosures. In 2022, the FASB issued ASU No. 2022-02, Financial Instruments – Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures (“ASU 2022-02”), which requires that entities disclose current period gross write-offs by year of origination for financing receivables and net investments in leases. For public entities, the provisions within ASU 2022-02 are to be applied prospectively and are effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. The Company will adopt ASU 2022-02 and will include the additional disclosures, as applicable, for any write-offs reflected in its consolidated financial statements effective for the year ending December 31, 2023.
Acquisitions	Acquisitions were accounted for as business combinations using the acquisition method of accounting in accordance with ASC 805, Business Combinations. Purchase price was allocated to the respective assets acquired and liabilities assumed based on the estimated fair values at the date of acquisitions. The results of operations for the following acquired and divested businesses are included in the consolidated results of the Company from the respective dates of acquisition and through the respective dates of disposition. Pro forma information for these acquired businesses is not provided because they did not have a material effect, individually or in aggregate, on the Company’s consolidated results of operations.
Leases, Company as Lessee	The Company uses the right-of-use model to account for its leases. ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. ROU assets and lease liabilities are recognized on the commencement date based on the present value of lease payments over the lease term. ROU assets are based on the lease liability and are increased by prepaid lease payments and decreased by lease incentives received. For leases where the Company is reasonably certain to exercise a renewal option, such option periods have been included in the determination of the Company’s ROU assets and lease liabilities. Certain leases require the Company to pay taxes, insurance, maintenance and other operating expenses associated with the leased asset. Such amounts are not included in the measurement of the ROU assets and lease liabilities to the extent they are variable in nature. These variable lease costs are recognized as variable lease expenses when incurred. As a practical expedient, lease agreements with lease and non-lease components are accounted for as a single lease component for all asset classes. The Company estimates contingent lease incentives when it is probable that the Company is entitled to the incentive at lease commencement. The Company elected the short-term lease recognition exemption for all leases that qualify. Therefore, leases with an initial term of 12 months or less are not recorded on the consolidated balance sheets; instead, lease payments are recognized as lease expense on a straight-line basis over the lease term. The depreciable life of the ROU assets and leasehold improvements are limited by the expected lease term unless the Company is reasonably certain of a transfer of title or purchase option. The Company uses its incremental borrowing rate to discount future lease payments in the calculation of the lease liability and ROU asset based on the information available on the commencement date for each lease. The Company’s leases typically do not provide an implicit rate. The determination of the incremental borrowing rate requires judgment and is determined using the Company’s current unsecured borrowing rate, adjusted for various factors such as collateralization, currency and term to align with the terms of the lease.

Summary of Significant Accounting Policies (Policies)

12 Months Ended

Dec. 31, 2022

The consolidated financial statements include the accounts of Fiserv, Inc. and its subsidiaries in which the Company holds a majority controlling financial interest. All intercompany transactions and balances between the Company and its subsidiaries have been eliminated in consolidation. Control is typically established when ownership and voting interests in an entity are greater than 50%. Investments in which the Company has significant influence but not control are accounted for using the equity method of accounting, for which the Company’s share of net income or loss is reported within income from investments in unconsolidated affiliates, and the related tax expense or benefit is reported within the income tax provision in the consolidated statements of income. Significant influence over an affiliate’s operations generally coincides with an ownership interest of between 20% and 50%; however, for partnerships and limited liability companies, an ownership interest of between 3% and 50% or board of director representation may also constitute significant influence.

The Company maintains a majority controlling financial interest in certain entities, mostly related to consolidated merchant alliances (see Note 19). Noncontrolling interests represent the minority shareholders’ share of the net income or loss and equity in consolidated subsidiaries. The Company’s noncontrolling interests presented in the consolidated statements of income include net income attributable to noncontrolling interests and redeemable noncontrolling interests. Noncontrolling interests are presented as a component of equity in the consolidated balance sheets. Noncontrolling interests that are redeemable upon the occurrence of an event that is not solely within the Company’s control are presented outside of equity and are carried at their estimated redemption value if it exceeds the initial carrying value of the redeemable interest (see Note 12).

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States (“U.S.”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ materially from those estimates.

Revenue Recognition

The Company generates revenue from the delivery of processing, service and product solutions. Revenue is measured based on consideration specified in a contract with a customer, and excludes any amounts collected on behalf of third parties. The Company recognizes revenue when it satisfies a performance obligation by transferring control over a product or service to a customer which may be at a point in time or over time. Additional information regarding the Company’s revenue recognition policies is included in Note 3 to the consolidated financial statements.

Significant Accounting Policy

ASC 606 outlines a single comprehensive model to use in accounting for revenue arising from contracts with customers. The core principle, involving a five-step process, of the revenue model is that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.

Revenue is measured based on consideration specified in a contract with a customer, and excludes any amounts collected on behalf of third parties. Taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction, that are collected by the Company from a customer, are excluded from revenue. Shipping and handling activities associated with outbound freight after control over a product has transferred to a customer are accounted for as a fulfillment activity and recognized as revenue at the point in time at which control of the goods transfers to the customer. As a practical expedient, the Company does not adjust the transaction price for the effects of a significant financing component if, at contract inception, the period between customer payment and the transfer of goods or services is expected to be one year or less.

Nature of Goods and Services

The Company’s operations are comprised of the Acceptance segment, the Fintech segment and the Payments segment (see Note 20). The following is a description of principal activities from which the Company generates its revenue. Contracts with customers are evaluated on a contract-by-contract basis as contracts may include multiple types of goods and services as described below.

Processing and Services

Processing and services revenue is generated from account- and transaction-based fees for merchant transaction processing and acquiring, electronic billing and payment services, electronic funds transfer and debit/credit processing services; consulting and professional services; and software maintenance for ongoing client support.

The Company recognizes processing and services revenue in the period in which the specific service is performed unless they are not deemed distinct from other goods or services in which revenue would then be recognized as control is transferred of the combined goods and services. The Company’s arrangements for processing and services typically consist of an obligation to provide specific services to its customers on a when and if needed basis (a stand-ready obligation) and revenue is recognized from the satisfaction of the performance obligations in the amount billable to the customer. These services are typically provided under a fixed or declining (tier-based) price per unit based on volume of service; however, pricing for services may also be based on minimum monthly usage fees. Fees for the Company’s processing and services arrangements are typically billed and paid on a monthly basis.

Product

Product revenue is generated from print and card production, software license, and hardware (primarily POS device) sales.

For software license agreements that are distinct, the Company recognizes software license revenue upon delivery, assuming a contract is deemed to exist. Revenue for arrangements with customers that include significant customization, modification or production of software such that the software is not distinct is typically recognized over time based upon efforts expended, such as labor hours, to measure progress towards completion. For arrangements involving hosted licensed software for the customer, a software element is considered present to the extent the customer has the contractual right to take possession of the software at any time during the hosting period without significant penalty and it is feasible for the customer to either operate the software on their own hardware or contract with another vendor to host the software. In certain instances, the Company may offer extended payment terms beyond one year. To the extent a significant financing component exists, it is calculated as the difference between the promised consideration and the present value of the software license fees utilizing a discount rate reflective of a separate financing transaction, and is recognized as interest income over the extended payment period. The cash selling price of the software license fee is recognized as revenue at the point in time when the software is transferred to the customer.

The Company sells or leases hardware (POS devices) and other peripherals as part of its contracts with customers. Hardware typically consists of POS terminals or Clover® devices. The Company does not manufacture hardware; rather, it purchases hardware from third-party vendors and holds such hardware in inventory until purchased by a customer. The Company accounts for sales of hardware as a separate performance obligation and recognizes the revenue at its standalone selling price when the customer obtains control of the hardware.

Significant Judgments in Application of the Guidance

The Company uses the following methods, inputs and assumptions in determining amounts of revenue to recognize:

Identification of Performance Obligations

To identify its performance obligations, the Company considers all of the goods or services promised in the contract regardless of whether they are explicitly stated or are implied by customary business practices. For multi-element arrangements, the Company accounts for individual goods or services as a separate performance obligation if they are distinct, the good or service is separately identifiable from other items in the arrangement and if a customer can benefit from it on its own or with other resources that are readily available to the customer. If these criteria are not met, the promised goods or services are accounted for as a combined performance obligation. Determining whether goods or services are distinct performance obligations that should be accounted for separately may require significant judgment.

Technology or service components from third parties are frequently embedded in or combined with the Company’s applications or service offerings. Whether the Company recognizes revenue based on the gross amount billed to a customer or the net amount retained involves judgment that depends on the relevant facts and circumstances, including the level of contractual responsibilities and obligations for delivering solutions to end customers, to determine whether control of goods and services is obtained prior to their transfer to a customer.

Determination of Transaction Price

The transaction price is determined based on the consideration to which the Company will be entitled in exchange for transferring products or services to the customer. The Company includes any fixed charges within its contracts as part of the total transaction price. To the extent that variable consideration is not constrained, the Company includes an estimate of the variable amount, as appropriate, within the total transaction price and updates its assumptions over the duration of the contract.

Assessment of Estimates of Variable Consideration

Many of the Company’s contracts with customers contain some component of variable consideration; however, the constraint will generally not result in a reduction in the estimated transaction price for most forms of variable consideration. The Company may constrain the estimated transaction price in the event of a high degree of uncertainty as to the final consideration amount owed because of an extended length of time over which fees may be adjusted.

Allocation of Transaction Price

The transaction price (including any discounts or rebates) is allocated between distinct goods and services in a multi-element arrangement based on their relative standalone selling prices. The standalone selling prices are determined based on the prices at which the Company separately sells each good or service. For items that are not sold separately, the Company estimates the standalone selling prices using available information such as market conditions and internally approved pricing guidelines. Judgment may be required to determine standalone selling prices for each performance obligation and whether it depicts the amount the Company expects to receive in exchange for the related good or service.

Contract Modifications

Contract modifications occur when the Company and its customers agree to modify existing customer contracts to change the scope or price (or both) of the contract or when a customer terminates some, or all, of the existing services provided by the Company. When a contract modification occurs, it requires the Company to exercise judgment to determine if the modification should be accounted for as (i) a separate contract, (ii) the termination of the original contract and creation of a new contract, or (iii) a cumulative catch up adjustment to the original contract. Further, contract modifications require the identification and evaluation of the performance obligations of the modified contract, including the allocation of consideration to the remaining performance obligations and the period of revenue recognition for each identified performance obligation.

Contract assets, reported within other long-term assets in the consolidated balance sheets, primarily result from revenue being recognized where payment is contingent upon the transfer of services to a customer over the contractual period. Contract liabilities primarily relate to advance consideration received from customers (deferred revenue) for which transfer of control occurs, and therefore revenue is recognized, as services are provided. Contract balances are reported in a net contract asset or liability position on a contract-by-contract basis at the end of each reporting period.

The Company applies the optional exemption under ASC 606 and does not disclose information about remaining performance obligations for account- and transaction-based processing fees that qualify for recognition under the as-invoiced practical expedient. These multi-year contracts contain variable consideration for stand-ready performance obligations for which the exact quantity and mix of transactions to be processed are contingent upon the customer’s request. The Company also applies the optional exemptions under ASC 606 and does not disclose information for variable consideration that is a sales-based or usage-based royalty promised in exchange for a license of intellectual property or that is allocated entirely to a wholly unsatisfied performance obligation or to a wholly unsatisfied promise to transfer a distinct good or service in a series. The amounts disclosed above as remaining performance obligations consist primarily of fixed or monthly minimum processing fees and maintenance fees under contracts with an original expected duration of greater than one year.

Contract Costs

The Company incurs incremental costs to obtain a contract as well as costs to fulfill contracts with customers that are expected to be recovered. These costs consist of sales commissions incurred only if a contract is obtained, and customer conversion or implementation related costs.Capitalized contract costs are amortized based on the transfer of goods or services to which the asset relates. The amortization period also considers expected customer lives and whether the asset relates to goods or services transferred under a specific anticipated contract. The amortization of capitalized sales commissions is included in selling, general and administrative expenses and amortization of capitalized conversion or implementation costs within cost of processing and services.

Cash and Cash Equivalents

Cash and cash equivalents consist of cash and investments with original maturities of 90 days or less and are stated at cost in the consolidated balance sheets, which approximates market value. Cash and cash equivalents that were restricted from use due to regulatory or other requirements are included in other long-term assets in the consolidated balance sheets. Cash and cash equivalents held on behalf of merchants and other payees are included in settlement assets in the consolidated balance sheets.

Allowance for Doubtful Accounts

The Company analyzes the collectability of trade accounts receivable by considering historical bad debts, client creditworthiness, current economic trends, changes in client payment terms and collection trends when evaluating the adequacy of the allowance for doubtful accounts. Any change in the assumptions used in analyzing a specific account receivable may result in an additional allowance for doubtful accounts being recognized in the period in which the change occurs.

Leases, Company as Lessor

The Company maintains certain leasing receivables associated with its POS terminal leasing businesses. Leasing receivables are included in prepaid expenses and other current assets and other long-term assets in the consolidated balance sheets. Interest income on the Company’s leasing receivables is recognized using the effective interest method, and is included within product revenue in the consolidated statements of income. Initial direct costs incurred to obtain operating leases and other sales-type leases, in which the fair value of the underlying asset is equal to its carrying amount at the lease commencement date, are deferred and recognized over the lease term. Initial direct costs to obtain a sales-type lease are expensed as incurred if the fair value of the underlying asset is different from its carrying amount at the lease commencement date. Additional information regarding the Company’s lease policies is included in Note 10 to the consolidated financial statements.The Company owns certain POS terminal equipment which it leases to merchants. Leases are classified as operating or sales-type leases based on factors such as the lease term, lease payments, and the economic life, fair value and estimated residual value of the asset. The terms of the leases typically range from one month to five years. For operating leases, the minimum lease payments received are recognized as lease income on a straight-line basis over the lease term and the leased asset is included in property and equipment, net in the consolidated balance sheets and depreciated over its estimated useful life. For sales-type leases, selling profit is recognized at the commencement date of the lease to the extent the fair value of the underlying asset is different from its carrying amount. Selling profit is directly impacted by the Company’s estimate of the amount to be derived from the residual value of the asset at the end of the lease term. The residual value of the asset is computed using various assumptions, including the expected value of the underlying asset at the end of the lease term. Unearned income is recognized as interest income over the lease term. For sales-type leases, the Company derecognizes the carrying amount of the underlying leased asset and recognizes a net investment in the leased asset in the consolidated balance sheets. The net investment in a leased asset is computed based on the present value of the minimum lease payments not yet received and the present value of the residual value of the asset.

Prepaid Expenses and Other Current Assets

Prepaid expenses represent advance payments for goods and services to be consumed in the future, such as maintenance, postage and insurance, and totaled $431 million and $410 million at December 31, 2022 and 2021, respectively.The Company offers merchants advance access to capital through its Clover Capital cash advance program. Under this program, merchants sell fixed amounts of their future credit card receivables to the Company in exchange for an up-front purchase price payment.

Settlement Assets and Obligations

Settlement assets and obligations result from timing differences between collection and fulfillment of payment transactions and collateral amounts held to manage merchant credit risk, primarily associated with the Company’s merchant acquiring services. Settlement assets represent cash received or amounts receivable from agents, payment networks, bank partners, merchants or direct consumers. Settlement obligations represent amounts payable to merchants and payees. Certain merchant settlement assets (included within settlement receivables) that relate to settlement obligations are held by partner banks to which the Company does not have legal ownership, but which the Company has the right to use, to satisfy the related settlement obligations. The Company records settlement obligations for amounts payable to merchants and for outstanding payment instruments issued to payees that have not yet been presented for settlement. Additional information regarding the Company’s settlement assets and obligations is included in Note 5 to the consolidated financial statements.

Allowance for Merchant Credit Losses

With respect to the Company’s merchant acquiring business, the Company’s merchant customers have the legal obligation to refund any charges properly reversed by the cardholder. However, in the event the Company is not able to collect the refunded amounts from the merchants, the Company may be liable for the reversed charges. The Company’s risk in this area primarily relates to situations where a cardholder has purchased goods or services to be delivered in the future. The Company requires cash deposits, guarantees, letters of credit or other types of collateral from certain merchants to mitigate this risk. Collateral held by the Company, or held by partner banks for the Company’s benefit, is classified within settlement assets and the obligation to repay the collateral is classified within settlement obligations in the consolidated balance sheets. The Company also utilizes a number of systems and procedures to manage merchant credit risk. Despite these efforts, the Company experiences losses due to merchant defaults. The aggregate merchant credit loss expense, recognized by the Company within cost of processing and services in the consolidated statements of income, was $62 million, $41 million and $113 million for the years ended December 31, 2022, 2021 and 2020, respectively. The amount of collateral available to the Company was $1.5 billion and $2.2 billion at December 31, 2022 and 2021, respectively. The Company maintains an allowance for merchant credit losses that are expected to exceed the amount of merchant collateral. The allowance includes estimated losses from anticipated chargebacks and fraud events that have been incurred on merchants’ payment transactions that have been processed but not yet reported to the Company, which is recorded within accounts payable and accrued expenses in the consolidated balance sheets, as well as estimated losses on refunded amounts to cardholders that have not yet been collected from the merchants, which is recorded within prepaid expenses and other current assets in the consolidated balance sheets. The allowance is based primarily on the Company’s historical experience of credit losses and other factors such as changes in economic conditions or increases in merchant fraud.

Property and Equipment

Property and equipment is reported at cost. Depreciation of property and equipment is computed primarily using the straight-line method over the shorter of the estimated useful life of the asset or the leasehold period, if applicable.

Intangible Assets

Customer related intangible assets represent customer contracts and relationships obtained as part of acquired businesses and are amortized using an accelerated amortization method which corresponds with the customer attrition rates used in the initial valuation of the intangibles over their estimated useful lives, generally ten to twenty years. Acquired software and technology represents software and technology intangible assets obtained as part of acquired businesses and is amortized using the straight-line method over their estimated useful lives, generally four to ten years. Trade names are amortized using the straight-line method over their estimated useful lives, generally eight to twenty years. Non-compete agreements are amortized using the straight-line method over their estimated useful lives, generally four to five years.

Purchased software represents software licenses purchased from third parties and is amortized using the straight-line method over their estimated useful lives, generally five years.

The Company continually develops, maintains and enhances its products and systems. Product development expenditures represented approximately 7%, 7% and 6% of the Company’s total revenue for the years ended December 31, 2022, 2021 and 2020, respectively. Research and development costs incurred prior to the establishment of technological feasibility are expensed as incurred. Routine maintenance of software products, design costs and other development costs incurred prior to the

establishment of a product’s technological feasibility are also expensed as incurred. Costs are capitalized commencing when the technological feasibility of the software has been established.

Capitalized software development costs represent the capitalization of certain costs incurred to develop new software or to enhance existing software which is marketed externally or utilized by the Company to process client transactions. Capitalized software development costs are amortized using the straight-line method over their estimated useful lives, generally five years.

The Company may, at its discretion, negotiate to pay an independent sales organization (“ISO”) an agreed-upon up-front amount in exchange for the ISO’s surrender of its right to receive commission payments from the Company related to future transactions of merchants referred by the ISO (“residual buyout”). The amount that the Company pays for these residual buyouts is capitalized and subsequently amortized using the straight-line method over the expected life of the merchant portfolios, generally five to nine years. The Company may also obtain residual buyouts as part of acquired businesses. Additional information regarding the Company’s identifiable intangible assets is included in Note 6 to the consolidated financial statements.

Goodwill

Goodwill represents the excess of purchase price over the fair value of identifiable assets acquired and liabilities assumed in a business combination. The Company evaluates goodwill for impairment on an annual basis, or more frequently if circumstances indicate possible impairment. Goodwill is tested for impairment at a reporting unit level, which is one level below the Company’s reportable segments. When assessing goodwill for impairment, the Company considers (i) the prior year’s amount of excess fair value over the carrying value of each reporting unit, (ii) the period of time since a reporting unit’s last quantitative test, (iii) the extent a reorganization or disposition changes the composition of one or more of the reporting units and (iv) other factors to determine whether or not to first perform a qualitative test. When performing a qualitative test, the Company assesses numerous factors to determine whether it is more likely than not that the fair value of its reporting units is less than their respective carrying values. Examples of qualitative factors that the Company assesses include its share price, its financial performance, market and competitive factors in its industry and other events specific to its reporting units. If the Company concludes that it is more likely than not that the fair value of a reporting unit is less than its carrying value, the Company performs a quantitative impairment test by comparing reporting unit carrying values to estimated fair values.

The Company elected to perform a quantitative test for certain reporting units, including those that changed in composition or where the prior year’s amount of excess fair value over carrying value was of a lower magnitude, and tested the remainder of its reporting units using a qualitative approach. The Company’s most recent annual impairment assessment of its reporting units in the fourth quarter of 2022 determined that its goodwill was not impaired as the estimated fair values exceeded the carrying values. However, it is reasonably possible that future developments related to the interest or currency exchange rate environments; a shift in strategic initiatives; a deterioration in financial performance or in the success of merchant alliances and relationships within a particular reporting unit; or significant changes in the composition of, or assumptions used in, the quantitative test on certain of the Company’s reporting units (such as an increase in risk-adjusted discount rates) could have a future material impact on one or more of the estimates and assumptions used to evaluate goodwill impairment. There is no accumulated goodwill impairment for the Company through December 31, 2022. Additional information regarding the Company’s goodwill is included in Note 7 to the consolidated financial statements.

Asset Impairment

The Company reviews property and equipment, lease right-of-use (“ROU”) assets, intangible assets and its investments in unconsolidated affiliates for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. The Company reviews capitalized software development costs for impairment at each reporting date. Recoverability of property and equipment, lease ROU assets, capitalized software development costs and other intangible assets is assessed by comparing the carrying amount of the asset to either the undiscounted future cash flows expected to be generated by the asset or the net realizable value of the asset, depending on the type of asset. The Company assesses lease ROU assets that are exited in advance of the non-cancellable lease terms by comparing the carrying values of the lease ROU assets to the discounted cash flows from estimated sublease payments. The Company’s investments in unconsolidated affiliates are assessed by comparing the carrying amount of the investments to their estimated fair values and are impaired if any decline in fair value is determined to be other than temporary. Measurement of any impairment loss is based on estimated fair value.

Fair Value Measurements

The Company applies fair value accounting for all assets and liabilities that are recognized or disclosed at fair value in its consolidated financial statements on a recurring basis. Fair value represents the amount that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities, the Company uses the hierarchy prescribed in Accounting

Standards Codification (“ASC”) 820, Fair Value Measurements (“ASC Topic 820”), and considers the principal or most advantageous market and the market-based risk measurements or assumptions that market participants would use in pricing the asset or liability. The three levels in the hierarchy are as follows:

•Level 1 – Quoted prices (unadjusted) for identical assets or liabilities in active markets that are accessible as of the measurement date.

•Level 2 – Inputs other than quoted prices within Level 1 that are observable either directly or indirectly, including but not limited to quoted prices in markets that are not active, quoted prices in active markets for similar assets or liabilities and observable inputs other than quoted prices such as interest rates or yield curves.

•Level 3 – Unobservable inputs reflecting management’s judgments about the assumptions that market participants would use in pricing the asset or liability, including assumptions about risk.

Additional information regarding the Company’s fair value measurements is included in Note 9 to the consolidated financial statements.

The fair values of cash equivalents, trade accounts receivable, settlement assets and obligations, accounts payable, and client deposits approximate their respective carrying values due to the short period of time to maturity. The Company maintains forward exchange contracts, designated as cash flow hedges, to hedge foreign currency exposure. The Company also maintains cross-currency rate swap contracts, designated as net investment hedges, to hedge a portion of its net investment in certain subsidiaries whose functional currencies are the Euro. These derivative instruments are measured on a recurring basis based on foreign currency spot rates and forwards quoted by banks and foreign currency dealers and are marked to market each period (see Note 13). Contingent consideration related to certain of the Company’s acquisitions (see Note 4) is estimated using the present value of a probability-weighted assessment approach based on the likelihood of achieving the earn-out criteria. The fair value of the Company’s contingent liability for current expected credit losses associated with its debt guarantees, as further described below, is estimated based on assumptions of future risk of default and the corresponding level of credit losses at the time of default.

Foreign Currency

The U.S. dollar is the functional currency of the Company’s U.S.-based businesses and certain foreign-based businesses. Where the functional currency differs from the U.S. dollar, assets and liabilities are translated into U.S. dollars at the exchange rates in effect at the balance sheet date. Revenue and expenses are translated at the average exchange rates during the reporting period. Gains and losses from foreign currency translation are recorded as a separate component of accumulated other comprehensive loss. Gains and losses from foreign currency transactions are included in determining net income for the reporting period.

Financial statements of subsidiaries located in highly inflationary economies outside of the U.S. are remeasured into U.S. dollars, and the foreign currency gains and losses from the remeasurement of monetary assets and liabilities are reflected in the consolidated statements of income, rather than in shareholders’ equity. The remeasurement of monetary assets and liabilities resulted in foreign currency exchange losses of $52 million and $5 million during the years ended December 31, 2022 and 2021, respectively, primarily related to Argentina. Foreign currency exchange losses resulting from the remeasurement of monetary assets and liabilities were nominal during the year ended December 31, 2020.

To reduce exposure to changes in the value of the Company’s net investments in certain of its foreign currency-denominated subsidiaries due to changes in foreign currency exchange rates, the Company uses fixed-to-fixed cross-currency rate swap contracts and foreign currency-denominated debt as economic hedges of its net investments in such foreign currency-denominated subsidiaries (see Note 13). Accordingly, foreign currency transaction gains or losses on the qualifying net investment hedge instruments are recorded as foreign currency translation, net of tax, within other comprehensive income (loss) in the consolidated statements of comprehensive income and will remain in accumulated other comprehensive loss within the consolidated balance sheets until the sale or complete liquidation of the underlying foreign subsidiaries.

Derivatives

Derivatives are entered into for periods consistent with related underlying exposures and are recorded in the consolidated balance sheets as either an asset or liability measured at fair value. If the derivative is designated as a cash flow hedge, changes in the fair value of the derivative are recorded as a component of accumulated other comprehensive loss and recognized in the consolidated statements of income when the hedged item affects earnings. If the derivative is designated as a net investment hedge, changes in the fair value of the derivative, net of tax, are recorded in the foreign currency translation component of other comprehensive income (loss) until the sale or complete liquidation of the underlying net investment. If the derivative is designated as a fair value hedge, changes in the fair value of the derivative are recorded in the same line item as the changes in the fair value of the hedged item and recognized in the consolidated statements of income. To the extent a derivative is not designated as a hedge, changes in fair value are recognized in the consolidated statements of income. The Company’s policy is to enter into derivatives with creditworthy institutions and not to enter into such derivatives for speculative purposes.

Employee Benefit Plans

The Company maintains frozen defined benefit pension plans covering certain employees in Europe and the U.S. The Company records actuarial gains/losses and prior service cost in the consolidated balance sheets and recognizes changes in these amounts during the year in which changes occur through other comprehensive income (loss). The Company uses various assumptions when computing amounts relating to its defined benefit pension plan obligations and their associated expenses (including the discount rate and the expected rate of return on plan assets). Additional information regarding the Company’s employee benefit plans is included in Note 14 to the consolidated financial statements.

Cost of Processing, Services, and Product

Cost of processing and services consists of costs directly associated with providing services to clients and includes the following: personnel; equipment and data communication; infrastructure costs, including costs to maintain software applications; client support; certain depreciation and amortization; and other operating expenses.

Income Taxes

Deferred tax assets and liabilities are recognized for the expected future tax consequences attributable to differences between financial statement carrying amounts of existing assets and liabilities and their respective tax basis, and net operating loss and tax credit carry-forwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. A valuation allowance is recorded against deferred tax assets if it is more likely than not that some portion or all of the deferred tax assets will not be realized.

Liabilities are established for unrecognized tax benefits, attributable to differences between a tax position taken or expected to be taken in a tax return and the benefit recognized in the financial statements. In establishing a liability for an unrecognized tax benefit, assumptions are made in determining whether, and the extent to which, a tax position will be sustained. A tax position is recognized only when it is more likely than not to be sustained upon examination by the relevant taxing authority, based on its technical merits. The amount of tax benefit recognized reflects the largest benefit the Company believes is more likely than not to be realized upon ultimate settlement. As additional information becomes available, the liability for unrecognized tax benefits is reevaluated and adjusted, as appropriate. Tax benefits ultimately realized can differ from amounts previously recognized due to uncertainties, with any such differences generally impacting the provision for income tax.

Net Income Per Share

Net income per share attributable to Fiserv, Inc. in each year is calculated using actual, unrounded amounts. Basic net income per share is computed by dividing net income attributable to Fiserv, Inc. by the weighted-average number of common shares outstanding during the year. Diluted net income per share is computed by dividing net income attributable to Fiserv, Inc. by the weighted-average number of common shares and common stock equivalents outstanding during the year. Common stock equivalents consist of outstanding stock options, unvested restricted stock units and unvested restricted stock awards, and are computed using the treasury stock method.

Recently Adopted Accounting Pronouncements and Recently Issued Accounting Pronouncements

Recently Adopted Accounting Pronouncements

In 2021, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2021-10, Government Assistance (Topic 832) (“ASU 2021-10”), which requires that an entity provide certain disclosures in its annual financial statements about transactions with a government that are accounted for by applying a grant or contribution accounting model by analogy. ASU 2021-10 is effective for all business entities for annual periods beginning after December 15, 2021 and may be applied either prospectively or retrospectively to the transactions reflected in the financial statements at the date of initial application. The Company adopted ASU 2021-10, with prospective application of the additional disclosures to the transactions reflected in its consolidated financial statements, for the year ending December 31, 2022. The adoption was not material and therefore did not have an impact on the Company’s financial statement disclosures.

In 2021, the FASB issued ASU No. 2021-08, Accounting for Contract Assets and Contract Liabilities from Contracts with Customers (“ASU 2021-08”), which requires that an entity recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with ASC Topic 606, Revenue from Contracts with Customers (“ASC 606”). Generally, this should result in recognition and measurement of contract assets and contract liabilities at carryover value consistent with how they were recognized and measured in the acquired company’s financial statements, providing consistent recognition and enhanced comparability with revenue contracts with customers not acquired in a business combination. Prior to adoption of ASU 2021-08, an acquirer generally recognized contract assets and contract liabilities acquired in a business combination at fair value on the acquisition date. For public entities, ASU 2021-08 is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. Entities are required to apply a prospective transition approach upon adoption, unless early adoption occurs in an interim period. The Company adopted ASU 2021-08 effective January 1, 2022, with prospective application to business combinations occurring after adoption, and the adoption did not have a material impact on the Company’s consolidated financial statements.

In 2021, the FASB issued ASU No. 2021-05, Leases (Topic 842): Lessors – Certain Leases with Variable Lease Payments (“ASU 2021-05”), which amends the lease classification requirements for lessors with certain leases containing variable payments. A lessor is to classify and account for a lease with variable lease payments that do not depend on an index or a rate as an operating lease if the lease would have been classified as a sales-type lease or a direct financing lease and the lessor would have otherwise recognized a day-one loss. For public entities, ASU 2021-05 is effective for fiscal years beginning after December 15, 2021, including interim periods within those fiscal years, with early adoption permitted. Entities that have adopted ASC Topic 842, Leases (“ASC Topic 842”), prior to the issuance of ASU 2021-05 may apply this update either retrospectively to leases that commenced or were modified on or after the adoption of ASC Topic 842 or prospectively to leases that commence or are modified on or after the date the entity first applies ASU 2021-05. The Company adopted ASU 2021-05 effective January 1, 2022, with prospective application to leases commencing or modified thereafter, and the adoption did not have a material impact on its consolidated financial statements.

Recently Issued Accounting Pronouncements

In 2022, the FASB issued ASU No. 2022-03, Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions (“ASU 2022-03”), which clarifies the guidance in ASC Topic 820, Fair Value Measurement, when measuring the fair value of an equity security subject to contractual restrictions that prohibit the sale of an equity security and introduces new disclosure requirements for equity securities subject to contractual sale restrictions that are measured at fair value in accordance with ASC Topic 820. For public entities, ASU 2022-03 is effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. The provisions within ASU 2022-03 are to be applied prospectively with any adjustments from the adoption recognized in earnings and disclosed on the date of adoption. The Company is currently assessing the impact the adoption of ASU 2022-03 will have on its consolidated financial statements and disclosures.

In 2022, the FASB issued ASU No. 2022-02, Financial Instruments – Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures (“ASU 2022-02”), which requires that entities disclose current period gross write-offs by year of origination for financing receivables and net investments in leases. For public entities, the provisions within ASU 2022-02 are to be applied prospectively and are effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. The Company will adopt ASU 2022-02 and will include the additional disclosures, as applicable, for any write-offs reflected in its consolidated financial statements effective for the year ending December 31, 2023.

Acquisitions

Acquisitions were accounted for as business combinations using the acquisition method of accounting in accordance with ASC 805, Business Combinations. Purchase price was allocated to the respective assets acquired and liabilities assumed based on the estimated fair values at the date of acquisitions. The results of operations for the following acquired and divested businesses are included in the consolidated results of the Company from the respective dates of acquisition and through the respective dates of disposition. Pro forma information for these acquired businesses is not provided because they did not have a material effect, individually or in aggregate, on the Company’s consolidated results of operations.

Leases, Company as Lessee

The Company uses the right-of-use model to account for its leases. ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. ROU assets and lease liabilities are recognized on the commencement date based on the present value of lease payments over the lease term. ROU assets are based on the lease liability and are increased by prepaid lease payments and decreased by lease incentives received. For leases where the Company is reasonably certain to exercise a renewal option, such option periods have been included in the determination of the Company’s ROU assets and lease liabilities. Certain leases require the Company to pay taxes, insurance, maintenance and other operating expenses associated with the leased asset. Such amounts are not included in the measurement of the ROU assets and lease liabilities to the extent they are variable in nature. These variable lease costs are recognized as variable lease expenses when incurred. As a practical expedient, lease agreements with lease and non-lease components are accounted for as a single lease component for all asset classes. The Company estimates contingent lease incentives when it is probable that the Company is entitled to the incentive at lease commencement. The Company elected the short-term lease recognition exemption for all leases that qualify. Therefore, leases with an initial term of 12 months or less are not recorded on the consolidated balance sheets; instead, lease payments are recognized as lease expense on a straight-line basis over the lease term. The depreciable life of the ROU assets and leasehold improvements are limited by the expected lease term unless the Company is reasonably certain of a transfer of title or purchase option. The Company uses its incremental borrowing rate to discount future lease payments in the calculation of the lease liability and ROU asset based on the information available on the commencement date for each lease. The Company’s leases typically do not provide an implicit rate. The determination of the incremental borrowing rate requires judgment and is determined using the Company’s current unsecured borrowing rate, adjusted for various factors such as collateralization, currency and term to align with the terms of the lease.
