Accounting Policies [Abstract]  
Business, consolidation and presentation
Business, consolidation and presentation— We are a leading pure play payments technology company delivering innovative software and services to our customers globally. Our technologies, services and employee expertise enable us to provide a broad range of solutions that allow our customers to operate their businesses more efficiently across a variety of channels around the world. We operate in three reportable segments: Merchant Solutions, Issuer Solutions and Business and Consumer Solutions, which are described in "Note 16—Segment Information." Global Payments Inc. and its consolidated subsidiaries are referred to collectively as "Global Payments," the "Company," "we," "our" or "us," unless the context requires otherwise.

On September 18, 2019, we consummated our merger with Total System Services, Inc. ("TSYS") (the "Merger") for total purchase consideration of $24.5 billion, primarily funded with shares of our common stock. Prior to the Merger, TSYS was a leading global payments provider, offering seamless, secure and innovative solutions to issuers, merchants and consumers. See "Note 2—Acquisitions" for further discussion of the Merger and other acquisitions.
These consolidated financial statements include our accounts and those of our majority-owned subsidiaries, and all intercompany balances and transactions have been eliminated in consolidation. Investments in entities that we do not control are accounted for using the equity or cost method, depending upon our ability to exercise significant influence over operating and financial policies. These consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States ("GAAP").
Use of estimates Use of estimates— The preparation of financial statements in conformity with GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements, as well as the reported amounts of revenues and expenses during the reported period. Actual results could differ materially from those estimates. In particular, the future magnitude, duration and effects of the COVID-19 pandemic are difficult to predict at this time, and the ultimate effect could result in additional charges related to the recoverability of assets, including financial assets, long-lived assets and goodwill and other losses. These consolidated financial statements reflect the financial statement effects of COVID-19 based upon management's estimates and assumptions utilizing the most currently available information.
Recently adopted and recently issued but not yet adopted accounting pronouncements
Recently adopted accounting pronouncements

Accounting Standards Update ("ASU") 2018-15— In August 2018, the Financial Accounting Standards Board ("FASB") issued ASU 2018-15, "Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract (A Consensus of the FASB Emerging Issues Task Force)." ASU 2018-15 provides additional guidance on the accounting for costs of implementation activities performed in a cloud computing arrangement (i.e., hosting arrangement) that is a service contract. The new guidance amends the definition of a hosting arrangement and requires a customer in a hosting arrangement that is a service contract to capitalize certain implementation costs following the internal-use software capitalization criteria within Accounting Standards Codification ("ASC") Subtopic 350-40.

We adopted ASU 2018-15 on January 1, 2020, applying the guidance prospectively to all implementation costs incurred on or after the date of adoption. The adoption of this standard did not have a material effect on our consolidated financial statements. We have historically capitalized implementation costs associated with cloud computing arrangements that are
service contracts following the guidance in Subtopic 350-40 and will continue to do so pursuant to the clarifications provided in the new guidance. We amortize capitalized implementation costs to expense on a straight-line basis over the term of the applicable hosting arrangement.
Our cloud computing arrangements involve services we use to support certain internal corporate functions as well as technology associated with revenue-generating activities. As of December 31, 2020, capitalized implementation costs, net of accumulated amortization, were $16.2 million and are presented within other noncurrent assets in the consolidated balance sheets. Amortization expense for the year ended December 31, 2020 was $3.1 million, and is presented in the same line item in the consolidated statements of income as the expense for the associated cloud services arrangement.
ASU 2016-13— We adopted ASU 2016-13, "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments" on January 1, 2020 using the modified retrospective transition method. The adoption of this standard resulted in a cumulative-effect adjustment to decrease retained earnings by $5.4 million, net of tax. The amendments in this update changed how we measure and recognize credit impairment for certain financial instruments measured at amortized cost. Under the current expected credit losses model required by ASU 2016-13, we recognize at asset inception and each subsequent reporting date an estimate of credit losses expected to occur over the remaining life of each pool of financial assets with similar risk characteristics.
ASU 2016-02— ASU 2016-02 “Leases” requires recognition of assets and liabilities for the rights and obligations created by leases and new disclosures about leases. We adopted ASU 2016-02, as well as other related clarifications and interpretive guidance issued by the FASB, on January 1, 2019 using the modified retrospective transition method. Under this transition method, we did not recast the prior period financial statements presented. We elected the transition package of three practical expedients, which among other things, allowed for the carryforward of historical lease classifications. We made an accounting policy election to not recognize assets or liabilities for leases with a term of less than 12 months and to account for all components in a lease arrangement as a single combined lease component for all of our then existing asset classes. In connection with the Merger, we acquired right-of-use assets that represent an additional asset class for computer equipment, for which we account for lease and nonlease components separately.

The adoption of ASU 2016-02 resulted in the measurement and recognition of lease liabilities in the amount of $274.0 million and right-of-use assets in the amount of $236.0 million as of January 1, 2019. Lease liabilities were measured as the present value of remaining lease payments, and the corresponding right-of-use assets were measured at an amount equal to the lease liabilities adjusted by the amounts of certain assets and liabilities, such as prepaid rent and deferred lease obligations, that we previously recognized on the balance sheet prior to the initial application of ASU 2016-02. To calculate the present value of remaining lease payments, we elected to use an incremental borrowing rate based on the remaining lease term at transition. Adoption did not have a material effect on any line items in our consolidated statement of income or on our cash flows from operating activities, investing activities or financing activities included in our consolidated statement of cash flows.

ASU 2014-09— We adopted ASU 2014-09, "Revenues from Contracts with Customers (Topic 606)" as well as other clarifications and technical guidance issued by the FASB related to this new revenue standard ("ASC 606") and ASC Subtopic 340-40: "Other Assets and Deferred Costs - Contracts with Customers" ("ASC 340-40") on January 1, 2018. We elected the modified retrospective transition method, which resulted in a net increase to retained earnings of $51.0 million for the cumulative effect of applying the standard. The primary components of the cumulative-effect adjustment were changes in the accounting for certain costs to obtain and fulfill customer contracts and the related income tax effects, which resulted in increases to other noncurrent assets and deferred income tax liabilities of $64.6 million and $15.6 million, respectively.

Upon the adoption of ASC 606, we present revenue net of payments made to certain third-parties, including payment networks. The adoption of ASC 606 did not have a material effect on any other line items in our consolidated statement of income for year ended December 31, 2018 or on any other line items in our consolidated balance sheet as of December 31, 2018 and had no effect on our cash flows from operating activities, investing activities or financing activities included in our consolidated statement of cash flows for the year ended December 31, 2018.
Recently issued pronouncements not yet adopted—

ASU 2019-12—In December 2019, the FASB issued ASU 2019-12, "Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes," which is intended to enhance and simplify various aspects of the accounting for income taxes. The amendments in this update remove certain exceptions to the general principles in ASC Topic 740 related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. ASU 2019-12 also clarifies and amends existing guidance to improve consistency in application of the accounting for franchise taxes, enacted changes in tax laws or rates and transactions that result in a step-up in the tax basis of goodwill. We will adopt ASU 2019-12 when it becomes effective for us on January 1, 2021. We have completed our evaluation of the effect of ASU 2019-12 on our consolidated financial statements and internal controls. We do not expect the adoption of this standard will have a material effect on our consolidated financial statements. 

ASU 2020-04—In March 2020, the FASB issued ASU 2020-04, "Reference Rate Reform (Topic 848)," which provides optional expedients and exceptions to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendments in this update apply only to contracts, hedging relationships, and other transactions that reference London Inter-bank Offered Rate ("LIBOR") or another reference rate expected to be discontinued because of reference rate reform. The expedients and exceptions provided by the amendments do not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022, except for hedging relationships existing as of December 31, 2022 for which an entity has elected certain optional expedients and which are retained through the end of the hedging relationship. The amendments in this update also include a general principle that permits an entity to consider contract modifications due to reference rate reform to be an event that does not require contract remeasurement at the modification date
or reassessment of a previous accounting determination. If elected, the optional expedients for contract modifications must be applied consistently for all eligible contracts or eligible transactions within the relevant ASC Topic or Industry Subtopic that contains the guidance that otherwise would be required to be applied. The amendments in this update were effective upon issuance and may be applied prospectively to contract modifications made and hedging relationships entered into or evaluated on or before December 31, 2022. A portion of our current indebtedness bears interest at a variable rate based on LIBOR. Furthermore, we have entered into hedging instruments to manage our exposure to fluctuations in the LIBOR benchmark interest rate. We are evaluating the effect of ASU 2020-04 on our consolidated financial statements.
Revenue recognition Revenue Recognition— At contract inception, we assess the goods and services promised in our contracts with customers and identify a performance obligation for each promise to transfer to the customer a good or service that is distinct. In accordance with ASC 606, we recognize revenue when a customer obtains control of promised services. The amount of revenue recognized reflects the consideration to which we expect to be entitled to receive in exchange for these services.
Merchant Solutions. Our customers in the Merchant Solutions segment contract with us for payment services, which we provide in exchange for consideration for completed transactions. Our payment solutions are similar around the world in that we enable our customers to accept card, electronic, check and digital-based payments. Our comprehensive offerings include, but are not limited to, authorization services, settlement and funding services, customer support and help-desk functions, chargeback resolution, payment security services, consolidated billing and statements and on-line reporting. In addition, we may sell or lease point-of-sale terminals or other equipment to customers.

For our payment services, the nature of our promise to the customer is that we stand ready to process transactions the customer requests on a daily basis over the contract term. Since the timing and quantity of transactions to be processed by us is not determinable, we view payment services to comprise an obligation to stand ready to process as many transactions as the customer requests. Under a stand-ready obligation, the evaluation of the nature of our performance obligation is focused on each time increment rather than the underlying activities. Therefore, we view payment services to comprise a series of distinct days of service that are substantially the same and have the same pattern of transfer to the customer. Accordingly, the promise to stand ready is accounted for as a single series performance obligation.

In order to provide our payment services, we route and clear each transaction through the applicable payment network. We obtain authorization for the transaction and request funds settlement from the card issuing financial institution through the payment network. When third parties are involved in the transfer of goods or services to our customer, we consider the nature of each specific promised good or service and apply judgment to determine whether we control the good or service before it is transferred to the customer or whether we are acting as an agent of the third party. To determine whether or not we control the good or service before it is transferred to the customer, we assess indicators including which party is primarily responsible for fulfillment and which party has discretion in determining pricing for the good or service, as well as other considerations. Based on our assessment of these indicators, we have concluded that our promise to our customer to provide our payment services is distinct from the services provided by the card issuing financial institutions and payment networks in connection with payment transactions. We do not have the ability to direct the use of and obtain substantially all of the benefits of the services provided by the card issuing financial institutions and payment networks before those services are transferred to our customer, and on that basis, we do not control those services prior to being transferred to our customer. As a result, we present our revenues net of the interchange fees retained by the card issuing financial institutions and the fees charged by the payment networks.

The majority of our payment services are priced as a percentage of transaction value or a specified fee per transaction, depending on the card type. We also charge other per occurrence fees based on specific services that may be unrelated to the number of transactions or transaction value.

Given the nature of the promise and the underlying fees based on unknown quantities or outcomes of services to be performed over the contract term, the total consideration is determined to be variable consideration. The variable consideration for our payment service is usage-based and, therefore, it specifically relates to our efforts to satisfy our payment services performance obligation. The variability is satisfied each day the service is provided to the customer. We directly ascribe variable fees to the distinct day of service to which it relates, and we consider the services performed each day in order to ascribe the appropriate amount of total fees to that day. Therefore, we measure revenues for our payment service on a daily basis based on the services that are performed on that day.

Certain of our technology-enabled customer arrangements contain multiple promises, such as payment services, perpetual software licenses, software-as-a-service ("SaaS"), maintenance, installation services, training and equipment, each of which is evaluated to determine whether it represents a separate performance obligation. SaaS arrangements are generally offered on a subscription basis, providing the customers with access to the SaaS platform along with general support and maintenance services. Because these promised services within our SaaS arrangements are delivered concurrently over the contract term, we account for these promises as if they are a single performance obligation that includes a series of distinct services with the same pattern of transfer to the customer. In addition, certain installation services are not considered distinct from the SaaS and are recognized over the expected period of benefit.

Once we determine the performance obligations and the transaction price, including an estimate of any variable consideration, we then allocate the transaction price to each performance obligation in the contract using a relative standalone selling price method. We determine standalone selling price based on the price at which the good or service is sold separately. If
the standalone selling price is not observable through past transactions, we estimate the standalone selling price by considering all reasonably available information, including market conditions, trends or other company- or customer-specific factors.

Substantially all of the performance obligations within our SaaS arrangements described above are satisfied over time. We satisfy the combined SaaS performance obligation by standing ready to provide access to the SaaS. Consideration for SaaS arrangements may consist of fixed or usage-based fees. Revenue is recognized over the period for which the services are provided or by directly ascribing any variable fees to the distinct day of service based on the services that are performed on that day. The performance obligations associated with equipment sales, perpetual software licenses and certain professional services are generally satisfied at a point in time when they are transferred to the customer. For certain other professional services that represent separate performance obligations, we generally use the input method and recognize revenue based on the number of hours incurred or services performed to date in relation to the total services expected to be required to satisfy the performance obligation.

Issuer Solutions. Issuer Solutions segment revenues are derived from long-term contracts with financial institutions and other financial service providers. Issuer Solutions customer contracts typically include an obligation to provide processing services to financial institutions and other financial services providers. Payment processing services revenues are generated primarily from charges based on the number of accounts on file, transactions and authorizations processed, statements generated and/or mailed, managed services, cards embossed and mailed, and other processing services for cardholder accounts on file. Most of these contracts have prescribed annual minimums, penalties for early termination, and service level agreements that may affect contractual fees if specific service levels are not achieved. We have determined that these processing services represent a stand-ready obligation comprising a series of distinct days of services that are substantially the same and have the same pattern of transfer to the customer.

Issuer Solutions contracts may also include additional performance obligations relating to loyalty redemption services and other professional services. Similar to processing services, we have determined that loyalty redemption services represent a stand-ready obligation comprising a series of distinct days of service that are substantially the same and have the same pattern of transfer to the customer.

To the extent a contract includes multiple promised services, we must apply judgment to determine whether promised services are capable of being distinct and are distinct in the context of the contract. If these criteria for being distinct are not met, the promised services are combined and accounted for as a single performance obligation.

The performance obligations to provide processing services and loyalty redemption services include variable consideration. The variable consideration for our services is usage-based and, therefore, it specifically relates to our efforts to satisfy our services performance obligation. The variability is satisfied each day the service is provided to the customer. We directly ascribe variable fees to the distinct day of service to which it relates, and we consider the services performed each day in order to ascribe the appropriate amount of total fees to that day. Therefore, we measure revenues for our services on a daily basis based on the services that are performed on that day.

Professional services performance obligations are satisfied over time. For professional services, we recognize revenue based on the labor hours incurred for time and materials projects or on a straight-line basis for fixed-fee projects.

In some cases, we pay certain of our customers a signing incentive at contract inception or renewal. Consideration paid to customers is accounted for as a reduction of the transaction price and recognized as a reduction in revenues as the related services are provided to the customer, typically over the contract term. The deferred portion of consideration paid to customers is classified within other assets in our consolidated balance sheets.

Business and Consumer Solutions. Business and Consumer Solution arrangements include a stand-ready performance obligation to provide account access and facilitate purchase transactions. Revenues principally consist of fees collected from cardholders and fees generated by cardholder activity in connection with the programs that we manage. Customers are typically charged a fee for each purchase transaction made using their cards, unless the customer is on a monthly or annual service plan, in which case the customer is instead charged a monthly or annual subscription fee, as applicable. Customers are also charged a monthly maintenance fee after a specified period of inactivity. We also charge fees associated with additional services offered in connection with our accounts, including the use of overdraft features, a variety of bill payment options, card replacement, foreign exchange and card-to-card transfers of funds initiated through our call centers.
We have determined that we have a right to consideration from a customer in an amount that corresponds directly with our performance completed to date. As a result, we recognize revenue in the amount to which we have a right to invoice. Revenues are recognized net of fees charged by the payment networks for services they provide in processing transactions routed through them.
Cash, cash equivalents and restricted cash
Cash, cash equivalents and restricted cash— Cash and cash equivalents include cash on hand and all liquid investments with a maturity of three months or less when purchased. We consider certain portions of our cash and cash equivalents to be unrestricted but not available for general purposes. The amount of cash that we consider to be available for general purposes does not include the following: (i) settlement-related cash balances, (ii) funds held as collateral for merchant losses ("Merchant Reserves") and (iii) funds held for customers. Settlement-related cash balances represent funds that we hold when the incoming amount from the card networks precedes the funding obligation to the merchant. Settlement-related cash balances are not restricted; however, these funds are generally paid out in satisfaction of a processing obligation the following day. Merchant Reserves serve as collateral to minimize contingent liabilities associated with any losses that may occur under the merchant agreement. We record a corresponding liability in settlement processing assets and settlement processing obligations in our consolidated balance sheet. While this cash is not restricted in its use, we believe that designating this cash as Merchant Reserves strengthens our fiduciary standing with financial institutions that sponsor us and is in accordance with guidelines set by the card networks. Funds held for customers and the corresponding liability include amounts collected prior to remittance to or at the direction of our customers.

Restricted cash consists of amounts deposited by customers for prepaid card transactions that are subject to local regulatory restrictions requiring appropriate segregation and restriction in their use. These amounts cannot be withdrawn or used for general operating activities under legal or regulatory restrictions. Restricted cash is included in prepaid expenses and other current assets in the consolidated balance sheet with a corresponding liability in accounts payable and accrued liabilities.
Accounts receivable, contract assets and contract liabilities Accounts receivable, contract assets and contract liabilities— A contract with a customer creates legal rights and obligations. As we perform under customer contracts, our right to consideration that is unconditional is considered to be accounts receivable. If our right to consideration for such performance is contingent upon a future event or satisfaction of additional performance obligations, the amount of revenues we have recognized in excess of the amount we have billed to the customer is recognized as a contract asset. Contract liabilities represent consideration received from customers in excess of revenues recognized. Contract assets and liabilities are presented net at the individual contract level in the consolidated balance sheet and are classified as current or noncurrent based on the nature of the underlying contractual rights and obligations.
Allowance for doubtful accounts Allowance for credit losses— We are exposed to credit losses on accounts receivable balances. We utilize a combination of aging and loss-rate methods to develop an estimate of current expected credit losses, depending on the nature and risk profile of the underlying asset pool. A broad range of information is considered in the estimation process, including historical loss information adjusted for current conditions, the effects of COVID-19 on our customers and expectations of future trends. The estimation process also includes consideration of qualitative and quantitative risk factors associated with the age of asset balances, expected timing of payment, contract terms and conditions, changes in specific customer risk profiles or mix of customers, geographic risk, industry or economic trends and relevant environmental factors. Accounts receivable is presented net of an allowance for credit losses of $20.6 million as of December 31, 2020.
The measurement of the allowance for credit losses is recognized through credit loss expense and is included as a component of selling, general and administrative expense in our consolidated statements of income. We recognized credit loss expense of $23.0 million for the year ended December 31, 2020. Write-offs are recorded in the period in which the asset is deemed to be uncollectible. Recoveries are recognized when received as a direct credit to the credit loss expense in the consolidated statements of income. Prior to the adoption of ASU 2016-13, credit losses on accounts receivable balances were recognized when an occurrence was deemed to be probable.

Revenues are recognized net of estimated billing adjustments. Adjustments to customer invoices are charged against the allowance for billing adjustments.
Contract costs Contract costs— We capitalize costs to obtain contracts with customers, including employee sales commissions and fees to business partners. At contract inception, we capitalize such costs that we expect to recover and that would not have been incurred if the contract had not been obtained. In certain cases in which costs related to obtaining customers are incurred after the inception of the customer contract, such costs are capitalized as the corresponding liability is recognized. We also capitalize certain costs incurred to fulfill our contracts with customers that (i) relate directly to the contract, (ii) are expected to generate resources that will be used to satisfy our performance obligation under the contract and (iii) are expected to be recovered through revenues generated under the contract. Capitalized costs to obtain and to fulfill contracts are included in other noncurrent assets. Contract costs are amortized to operating expense in our consolidated statements of income on a systematic basis consistent with the transfer to the customer of the goods or services to which the asset relates. Amortization of capitalized costs to obtain customer contracts is included in selling, general and administrative expenses in the consolidated statements of income, while amortization of capitalized costs to fulfill customer contracts is included in cost of services. We utilize a straight-line or proportional amortization method depending upon which method best depicts the pattern of transfer of the goods or services to the customer. We amortize these assets over the expected period of benefit, which, based on the factors noted above, is typically three to seven years. In order to determine the appropriate amortization period for capitalized contract costs, we consider a combination of factors, including customer attrition rates, estimated terms of customer relationships, the useful lives of technology we use to provide goods and services to our customers, whether future contract renewals are expected and if there is any incremental commission expected to be paid associated with a contract renewal. Costs to obtain a contract with an expected period of benefit of one year or less are recognized as an expense when incurred. We evaluate contract costs for impairment by comparing, on a pooled basis, the expected future net cash flows from underlying customer relationships to the carrying amount of the capitalized contract costs.
Up-front distributor and partner payments Up-front distributor and partner payments— We capitalize certain up-front contractual payments to third-party distributors and partners and recognize the capitalized amount as expense ratably over the period of benefit, which is generally the contract period. If the contract requires the distributor or partner to perform specific acts and no other conditions exist for the distributor or partner to earn or retain the up-front payment, then we recognize the capitalized amount as an expense when the performance conditions have been met. Up-front distributor and partner payments are classified on our consolidated balance sheets within prepaid expenses and other current assets and other noncurrent assets and the related expense is reported within selling, general and administrative expenses in our consolidated statements of income.
Settlement processing assets and obligations
Settlement processing assets and obligations— Funds settlement refers to the process in our Merchant Solutions segment of transferring funds between card issuers and merchants for merchant sales and credits processed on our systems. We use our internal network to provide funding instructions to financial institutions that in turn fund the merchants. We process funds settlement under two models, a sponsorship model and a direct membership model.

Under the sponsorship model, we are designated as an independent sales organization by Mastercard and Visa, which means that member clearing banks ("Member") sponsor us and require our adherence to the standards of the payment networks. In certain markets, we have sponsorship or depository and clearing agreements with financial institution sponsors. These agreements allow us to route transactions under the Members' control and identification numbers to clear credit card transactions through Mastercard and Visa. In this model, the standards of the payment networks restrict us from performing funds settlement or accessing merchant settlement funds, and, instead, require that these funds be in the possession of the Member until the merchant is funded.
Under the direct membership model, we are members in various payment networks, allowing us to process and fund transactions without third-party sponsorship. In this model, we route and clear transactions directly through the card brand’s network and are not restricted from performing funds settlement. Otherwise, we process these transactions similarly to how we process transactions in the sponsorship model. We are required to adhere to the standards of the payment networks in which we are direct members. We maintain relationships with financial institutions, which may also serve as our Member sponsors for other card brands or in other markets, to assist with funds settlement.

Timing differences, interchange fees, merchant reserves and exception items cause differences between the amount received from the payment networks and the amount funded to the merchants. These intermediary balances arising in our settlement process are reflected as settlement processing assets and obligations on our consolidated balance sheets.

Settlement processing assets and obligations include the following components:

•Interchange reimbursement. Our receivable from merchants for the portion of the discount fee related to reimbursement of the interchange fee.

•Receivable from Members. Our receivable from the Members for transactions in which we have advanced funding to the Members to fund merchants in advance of receipt of funding from payment networks.

•Receivable from networks. Our receivable from a payment network for transactions processed on behalf of merchants where we are a direct member of that particular network.

•Exception items. Items such as customer chargeback amounts received from merchants.

•Merchant Reserves. Reserves held to minimize contingent liabilities associated with losses that may occur under the merchant agreement.

•Liability to Members. Our liability to the Members for transactions that have not yet been funded to the merchants.

•Liability to merchants. Our liability to merchants for transactions that have been processed but not yet funded where we are a direct member of a particular payment network.

•Allowance for credit and other merchant losses on settlement assets. Allowances, charges or expected credit losses on chargebacks, merchant fraud or other merchant-related reason.

We apply offsetting to our settlement processing assets and obligations where a right of setoff exists. In the sponsorship model, we apply offsetting by Member agreement because the Member is ultimately responsible for funds settlement. With these Member transactions, we do not have access to the gross proceeds of the receivable from the payment networks and, thus, do not have a direct obligation or any ability to satisfy the payable to fund the merchant. In these situations, we apply offsetting to determine a net position for each Member agreement. If that net position is an asset, we reflect the net amount in settlement processing assets on our consolidated balance sheet. If that net position is a liability, we reflect the net amount in settlement processing obligations on our consolidated balance sheet. In the direct membership model, offsetting is not applied, and the individual components are presented as an asset or obligation based on the nature of that component.
Property and equipment Property and equipment— Property and equipment are stated at cost less accumulated depreciation and amortization. Depreciation and amortization are generally calculated using the straight-line method. Leasehold improvements are amortized over the lesser of the remaining term of the lease and the useful life of the asset.
Software We develop software that is used to provide services to customers. Capitalization of internal-use software, primarily associated with operating platforms, occurs when we have completed the preliminary project stage, management authorizes the project, management commits to funding the project, it is probable the project will be completed and the project will be used to perform the function intended. The preliminary project stage consists of the conceptual formulation of alternatives, the evaluation of alternatives, the determination of existence of needed technology and the final selection of alternatives. Costs incurred during the preliminary project stage are recognized as expense as incurred. Capitalized internal-use software is amortized over its estimated useful life, which is typically two to ten years, in a manner that best reflects the pattern of economic use of the assets.
Goodwill and Other intangible assets
Goodwill— We perform our annual goodwill impairment test as of October 1 each year. We test goodwill for impairment at the reporting unit level annually and more often if an event occurs or circumstances change that indicate the fair value of a reporting unit is below its carrying amount. We have the option of performing a qualitative assessment of impairment to determine whether any further quantitative assessment for impairment is necessary. The option of whether or not to perform a qualitative assessment is made annually and may vary by reporting unit.

Factors we consider in the qualitative assessment include general macroeconomic conditions, industry and market conditions, cost factors, overall financial performance of our reporting units, events or changes affecting the composition or carrying amount of the net assets of our reporting units, sustained decrease in our share price, and other relevant entity-specific events. If we elect to bypass the qualitative assessment or if we determine, on the basis of qualitative factors, that the fair value of the reporting unit is more likely than not less than the carrying amount, a quantitative test would be required.

The quantitative assessment compares the fair value of the reporting unit to its carrying amount, and recognizes an impairment loss for the amount by which a reporting unit’s carrying amount exceeds its fair value, without exceeding the total amount of goodwill allocated to that reporting unit. When applying the quantitative assessment, we determine the fair value of our reporting units based on a weighted average of multiple valuation techniques, principally a combination of an income approach and a market approach. The income approach calculates a value based upon the present value of estimated future cash flows, while the market approach uses earnings multiples of similarly situated guideline public companies. Determining the fair value of a reporting unit involves judgment and the use of significant estimates and assumptions, which include assumptions regarding the revenue growth rates and operating margins used to calculate estimated future cash flows, risk-adjusted discount rates and future economic and market conditions.

Our reporting units consist of the following: North America Payment Solutions, Integrated Solutions, Vertical Market Software Solutions, Europe Merchant Solutions, Spain Merchant Solutions, Asia-Pacific Merchant Solutions, Issuer Solutions and Business and Consumer Solutions. As of October 1, 2020, we performed a quantitative assessment of impairment for our Issuer Solutions and Business and Consumer Solutions reporting units and a qualitative assessment for all other reporting units. We determined on the basis of the quantitative assessments of our Issuer Solutions and Business and Consumer Solutions reporting units that the fair value of each reporting unit is equal to or greater than its respective carrying amount. Additionally, we determined on the basis of the qualitative factors that the fair value of other reporting units was not more likely than not less than the respective carrying amounts. Our current year assessments also included consideration of the expected near term effects of the COVID-19 pandemic on revenues and our cost mitigation efforts, as well as longer term performance expectations. We believe that the fair value of each of our reporting units is substantially in excess of its carrying amount, except for Issuer Solutions and Business and Consumer Solutions for which the respective carrying amounts approximate fair value since they were recently acquired in the Merger.

Other intangible assets— Other intangible assets include customer-related intangible assets (such as customer lists, merchant contracts and referral agreements), contract-based intangible assets (such as noncompete agreements, distributor agreements and processing rights), acquired technologies, trademarks and trade names associated with business combinations. These assets are amortized over their estimated useful lives. The useful lives for customer-related intangible assets are determined based primarily on forecasted cash flows, which include estimates for the revenues, expenses, and customer attrition associated with the assets. The useful lives of contract-based intangible assets are equal to the terms of the agreements. The useful lives of amortizable trademarks and trade names are based on an estimate of the period over which we will earn revenues for the related brands, including contemplation of any future plans to use the trademarks and trade names in the applicable markets.

We use the straight-line method of amortization for our acquired technologies, trademarks and trade names and contract-based intangibles. Amortization for most of our customer-related intangible assets is determined using an accelerated method. Under this accelerated method, the first step in determining the amortization expense for any period is that we divide the expected cash flows for that period that were used in determining the acquisition-date fair value of the asset by the expected total cash flows over the estimated life of the asset. We then multiply that ratio by the initial carrying amount of the asset to arrive at the amortization expense for that period. If the cash flow patterns that we experience differ significantly from our
initial estimates, we adjust the amortization schedule prospectively. We believe that our accelerated method reflects the expected pattern of the benefit to be derived from the acquired customer relationships.
Impairment of long-lived assets Impairment of long-lived assets— We regularly evaluate whether events and circumstances have occurred that indicate the carrying amount of property and equipment and finite-life intangible assets may not be recoverable. When factors indicate that these long-lived assets should be evaluated for possible impairment, we assess the potential impairment by determining whether the carrying amount of such long-lived assets will be recovered through the future undiscounted cash flows expected from use of the asset and its eventual disposition. The evaluation is performed at the asset group level, which is the lowest level of identifiable cash flows. If the carrying amount of the asset group is determined not to be recoverable, a write-down to fair value is recorded. Fair values are determined based on quoted market prices or discounted cash flow analysis as applicable. We regularly evaluate whether events and circumstances have occurred that indicate the useful lives of property and equipment and finite-life intangible assets may warrant revision.
Leases Leases— We evaluate each of our lease and service arrangements at inception to determine if the arrangement is, or contains, a lease and the appropriate classification of each identified lease. A lease exists if we obtain substantially all of the economic benefits of, and have the right to control the use of, an asset for a period of time. Right-of-use assets represent our right to use an underlying asset for the lease term, and lease liabilities represent our obligation to make lease payments arising from the lease agreement. We recognize right-of-use assets and lease liabilities at the lease commencement date based on the present values of fixed lease payments over the term of the lease. Right-of-use assets may also be adjusted to reflect any prepayments made or any incentive payments received. Operating lease costs and depreciation expense for finance leases are recognized as expense on a straight-line basis over the lease term. We consider a termination or renewal option in the determination of the lease term when it is reasonably certain that we will exercise that option. Because our leases generally do not provide a readily determinable implicit interest rate, we use an incremental borrowing rate to measure the lease liability and associated right-of-use asset at the lease commencement date. The incremental borrowing rate used is a fully collateralized rate that considers our credit rating, market conditions and the term of the lease at the lease commencement date.
Equity method investments Equity method investments— We have certain investments, including a 45% investment in China UnionPay Data Co., Ltd., which we account for using the equity method of accounting. Equity method investments are recorded initially at cost and subsequently adjusted for equity in earnings, cash contributions and distributions, and foreign currency translation adjustments.
Income taxes
Income taxes— Deferred income taxes are determined based on the difference between the financial statement and tax bases of assets and liabilities using enacted tax laws and rates. A valuation allowance is provided when it is more likely than not that some portion or all of the deferred tax assets will not be realized.

We periodically assess our tax exposures related to periods that are open to examination. Based on the latest available information, we evaluate our tax positions to determine whether the position will more likely than not be sustained upon examination by the U.S. Internal Revenue Service or other taxing authorities. If we do not reach a more-likely-than-not determination, no benefit is recognized. If we determine that the tax position is more likely than not to be sustained, we recognize the largest amount of benefit that is more likely than not to be realized when the tax position is settled. We present
interest and penalties related to unrecognized income tax benefits in interest and selling, general and administrative expenses, respectively, in our consolidated statements of income.
Derivative instruments
Derivative instruments— We may use interest rate swaps or other derivative instruments to manage a portion of our exposure to the variability in interest rates. Our objective in managing our exposure to fluctuation in interest rates is to better control this element of cost and to mitigate the earnings and cash flow volatility associated with changes in applicable rates. We have established policies and procedures that encompass risk-management philosophy and objectives, guidelines for derivative instrument usage, counterparty credit approval, and the monitoring and reporting of derivative activity. We do not use derivative instruments for speculation.

At inception, we formally designate and document instruments that qualify for hedge accounting of underlying exposures. When qualified for hedge accounting, these financial instruments are recognized at fair value in our consolidated balance sheets, and changes in fair value are recognized as a component of other comprehensive income (loss) and included in accumulated other comprehensive loss within equity in our consolidated balance sheets. Cash flows resulting from settlements are presented as a component of cash flows from operating activities within our consolidated statements of cash flows.

We formally assess, both at inception and at least quarterly, whether the financial instruments used in hedging transactions are effective at offsetting changes in cash flows of the related underlying exposure. Fluctuations in the value of these instruments generally are offset by changes in the forecasted cash flows of the underlying exposures being hedged. This offset is driven by the high degree of effectiveness between the exposure being hedged and the hedging instrument. We designated each of our active interest rate swap agreements as a cash flow hedge of interest payments on variable rate borrowings. See "Note 8—Long-Term Debt and Lines of Credit" for more information about our interest rate swaps.
Fair value measurements Fair value measurements— Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the reporting date. GAAP establishes a fair value hierarchy that categorizes the inputs to valuation techniques into three broad levels. Level 1 inputs utilize quoted prices in active markets for identical assets or liabilities. Level 2 inputs are based on other observable market data, such as quoted prices for similar assets and liabilities, and inputs other than quoted prices that are observable such as interest rates and yield curves. Level 3 inputs are developed from unobservable data reflecting our assumptions and include situations where there is little or no market activity for the asset or liability.
Fair value of financial instruments Fair value of financial instruments— The carrying amounts of cash and cash equivalents, restricted cash, receivables, settlement lines of credit, accounts payable and accrued liabilities, approximate their fair value given the short-term nature of these items. The estimated fair value of our senior notes was based on quoted market prices in an active market and is considered to be a Level 1 measurement of the valuation hierarchy. Certain of our long-term debt arrangements include variable interest rates. The carrying amount of long-term debt with variable interest rates, exclusive of debt issuance costs, approximated fair value, which is calculated using Level 2 inputs. The fair values of our swap agreements were determined based on the present value of the estimated future net cash flows using implied rates in the applicable yield curve as of the valuation date, and classified within Level 2 of the valuation hierarchy. See "Note 8—Long-Term Debt and Lines of Credit" for further information. We also have investments in equity instruments without readily determinable fair value. As permitted, we have elected a measurement alternative for equity instruments that do not have readily determinable fair values. Under such alternative, these instruments are measured at cost plus or minus any changes resulting from observable price changes in orderly transactions for an identical or similar investment of the same issuer less any impairments. Any resulting change in carrying amount would be reflected in net income.
Foreign currencies Foreign currencies— We have significant operations in a number of foreign subsidiaries whose functional currency is the local currency. The assets and liabilities of subsidiaries whose functional currency is a foreign currency are translated into the reporting currency at the period-end rate of exchange. Income statement items are translated at the weighted-average rates prevailing during the period. The resulting translation adjustment is presented as a component of other comprehensive income and is included in accumulated comprehensive income within equity in our consolidated balance sheets.Gains and losses on transactions denominated in currencies other than the functional currency are generally included in determining net income for the period. For the years ended December 31, 2020, 2019 and 2018, our transaction gains and losses were insignificant. Transaction gains and losses on intercompany balances of a long-term investment nature are presented as a component of other comprehensive income and included in accumulated comprehensive income within equity in our consolidated balance sheets.
Earnings per share
Earnings per share— Basic earnings per share ("EPS") is computed by dividing reported net income attributable to Global Payments by the weighted-average number of shares outstanding during the period. Earnings available to common shareholders is the same as reported net income attributable to Global Payments for all periods presented.
 
Diluted EPS is computed by dividing net income attributable to Global Payments by the weighted-average number of shares outstanding during the period, including the effect of share-based awards that would have a dilutive effect on earnings per share. All stock options with an exercise price lower than the average market share price of our common stock for the period are assumed to have a dilutive effect on EPS. During the year ended December 31, 2020 there were 124,888 stock options that had an antidilutive effect on the computation of diluted EPS. During the years ended December 31, 2019 and 2018, there were no stock options that would have an antidilutive effect on the computation of diluted EPS.
Repurchased shares Repurchased shares— We account for the retirement of repurchased shares using the par value method under which the repurchase price is charged to paid-in capital up to the amount of the original issue proceeds of those shares. When the repurchase price is greater than the original issue proceeds, the excess is charged to retained earnings. We use a last-in, first-out cost flow assumption to identify the original issue proceeds of the shares repurchased.
