Summary of Significant Accounting Policies | Summary of Significant Accounting Policies Organization Mastercard Incorporated and its consolidated subsidiaries, including Mastercard International Incorporated (“Mastercard International” and together with Mastercard Incorporated, “Mastercard” or the “Company”), is a technology company in the global payments industry. Mastercard connects consumers, financial institutions, merchants, governments, digital partners, businesses and other organizations worldwide by enabling electronic payments and making those payment transactions secure, simple, smart and accessible. The Company makes payments easier and more efficient by providing a wide range of payment solutions and services using its family of well-known and trusted brands, including Mastercard®, Maestro® and Cirrus®. The Company operates a payments network that provides choice and flexibility for consumers, merchants and Mastercard customers. Through its unique and proprietary global payments network, the Company switches (authorizes, clears and settles) payment transactions. The Company has additional payments capabilities that include automated clearing house (“ACH”) transactions (both batch and real-time account-based payments). Using these capabilities, the Company offers consumer and commercial payment products, captures new payment flows and provides services and solutions. The Company’s services and solutions include, among others, security solutions, consumer acquisition and engagement services, and business and market insights, all of which draw on Mastercard’s principled and responsible use of secure data. The Company’s capabilities strengthen, reinforce and complement each other and are fundamentally interdependent. For the global payments network, Mastercard’s franchise model sets the standards and ground-rules that balance value and risk across all stakeholders and allows for interoperability among them. The Company employs a multi-layered approach to help protect the global payments ecosystem in which it operates. Mastercard is not a financial institution. The Company does not issue cards, extend credit, determine or receive revenue from interest rates or other fees charged to account holders by issuers, or establish the rates charged by acquirers in connection with merchants’ acceptance of the Company’s products. In most cases, account holder relationships belong to, and are managed by, the Company’s financial institution customers. Significant Accounting Policies Consolidation and basis of presentation - The consolidated financial statements include the accounts of Mastercard and its majority-owned and controlled entities, including any variable interest entities (“VIEs”) for which the Company is the primary beneficiary. Investments in VIEs for which the Company is not considered the primary beneficiary are not consolidated and are accounted for as marketable, equity method or measurement alternative method investments and recorded in other assets on the consolidated balance sheets. At December 31, 2024 and 2023, there were no significant VIEs that required consolidation and the investments were not considered material to the consolidated financial statements. The Company consolidates acquisitions as of the date the Company has obtained a controlling financial interest. Intercompany transactions and balances have been eliminated in consolidation. Certain prior period amounts have been reclassified to conform to the 2024 presentation. The reclassification had no impact on previously reported net revenue, operating income or net income. The Company follows accounting principles generally accepted in the United States of America (“GAAP”). Non-controlling interests represent the equity interest not owned by the Company and are recorded for consolidated entities in which the Company owns less than 100% of the interests. Changes in a parent’s ownership interest while the parent retains its controlling interest are accounted for as equity transactions, and upon loss of control, retained ownership interests are remeasured at fair value, with any gain or loss recognized in earnings. For 2024, 2023 and 2022, net income/(losses) attributable to non-controlling interests were not material and, as a result, amounts are included on the consolidated statements of operations within other income (expense). Use of estimates - The preparation of financial statements in conformity with GAAP 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 periods. Future events and their effects cannot be predicted with certainty; accordingly, accounting estimates require the exercise of judgment. These financial statements were prepared using information reasonably available as of December 31, 2024 and through the date of this Report. The accounting estimates used in the preparation of the Company’s consolidated financial statements may change as new events occur, as more experience is acquired, as additional information is obtained and as the Company’s operating environment changes. Actual results may differ from these estimates. Revenue recognition - Revenue is recognized to depict the transfer of promised services to customers in an amount that reflects the consideration to which the Company expects to be entitled to in exchange for those services. Revenue from the Company’s payment network is primarily generated by charging fees to customers (issuers, acquirers and other market participants) for providing switching and other network-related services, as well as by charging fees to customers based primarily on the gross dollar volume of activity (GDV, which includes both domestic and cross-border volume) on the cards that carry the Company’s brands. Revenue is recognized in the period in which the related transactions and volume occur. Certain volume-based revenue is determined from information reported by customers. Revenue from the Company’s value-added services and solutions is generated through either fixed or transaction-based fees. These services and solutions can be integrated and sold with the Company’s payment network services or can be sold on a stand-alone basis. For those contracts that include multiple performance obligations, the Company allocates revenue to each performance obligation based on its relative standalone selling price (“SSP”). The SSP is the price at which the Company would sell a promised product or service separately in similar circumstances to similar customers. Revenue from the Company’s value-added services and solutions is recognized in the period in which the related services and solutions are performed or transactions occur. For services provided to customers where delivery involves the use of a third-party, the Company recognizes revenue on a gross basis if it acts as the principal, controlling the service to the customer, or on a net basis if it acts as the agent, arranging for the service to be provided. Mastercard has business agreements with certain customers that provide for rebates and incentives within net revenue that could be either fixed or variable. Fixed incentives typically represent payments to a customer directly related to entering into an agreement, which are generally capitalized and amortized over the life of the agreement on a straight-line basis. Capitalized customer incentives are included in prepaid expenses and other current assets and other assets on the consolidated balance sheets. Variable rebates and incentives are recorded primarily when volume- and transaction-based revenues are recognized over the contractual term. Variable rebates and incentives are calculated based upon estimated customer performance, such as volume thresholds, and the terms of the related business agreements. Customer incentives to be paid to customers under business agreements are included in accrued expenses and other liabilities on the consolidated balance sheets. Certain of the Company’s contracts may include options to receive additional value-added services and solutions. The Company accounts for the option as a distinct performance obligation if the option provides a material right to the customer. Material rights are incremental to the standard offerings, which a customer would not have received without entering into the contract. If a material right exists in a contract, revenue allocated to the option is deferred and recognized as revenue when those future products or services are transferred or when the option expires. The value of the option is based on observable prices in the contract or on a relative SSP basis. Contract assets include unbilled consideration typically resulting from executed value-added services and solutions performed for customers in connection with Mastercard’s payments network service arrangements. Collection for these services typically occurs over the contractual term. Contract assets are included in prepaid expenses and other current assets and other assets on the consolidated balance sheets. The Company defers the recognition of revenue when consideration has been received prior to the satisfaction of performance obligations. As these performance obligations are satisfied, revenue is subsequently recognized. Deferred revenue primarily relates to certain value-added services and solutions. Deferred revenue is included in other current liabilities and other liabilities on the consolidated balance sheets. Business combinations - The Company accounts for business combinations under the acquisition method of accounting. The Company measures the tangible and intangible identifiable assets acquired, liabilities assumed, any non-controlling interest in the acquiree and contingent consideration at fair value as of the acquisition date. Acquisition-related costs are expensed as incurred and are included in general and administrative expenses on the consolidated statements of operations. Any excess purchase price over the fair value of net assets acquired, including identifiable intangible assets, is recorded as goodwill. Measurement period adjustments, if any, to the preliminary estimated fair value of the intangibles assets as of the acquisition date are recorded in goodwill. Goodwill and other intangible assets - Indefinite-lived intangible assets consist of goodwill and customer relationships. Goodwill represents the synergies expected to arise after the acquisition date and the assembled workforce. Finite-lived intangible assets consist of capitalized software costs, intangible assets acquired in business combinations (including customer relationships and acquired technology) and other intangible assets. Intangible assets with finite useful lives are amortized over their estimated useful lives, on a straight-line basis, which range from one The valuation methods for goodwill and other intangible assets acquired in business combinations involve assumptions concerning comparable company multiples, discount rates, growth projections and other assumptions of future business conditions. The Company uses various valuation techniques to determine the fair value of its intangible assets, primarily discounted cash flows analysis, relief-from-royalty and multi-period excess earnings. As the assumptions employed to measure these assets are based on management’s judgment using internal and external data, these fair value determinations are classified in Level 3 of the Valuation Hierarchy (as defined in Fair value subsection below). Impairment of assets - Goodwill and indefinite-lived intangible assets are not amortized but tested annually for impairment at the reporting unit level in the fourth quarter, or sooner when circumstances indicate an impairment may exist. The impairment evaluation for goodwill utilizes a qualitative assessment to determine whether it is more likely than not that goodwill is impaired. The qualitative factors may include, but are not limited to, macroeconomic conditions, industry and market conditions, operating environment, financial performance and other relevant events. If it is determined that it is more likely than not that goodwill is impaired, then the Company is required to perform a quantitative goodwill impairment test. If the fair value of the reporting unit exceeds the carrying value, goodwill is not impaired. If the fair value of the reporting unit is less than its carrying value, goodwill is impaired and the excess of the reporting unit’s carrying value over the fair value is recognized as an impairment charge. The impairment test for indefinite-lived intangible assets consists of a qualitative assessment to evaluate relevant events and circumstances that could affect the significant inputs used to determine the fair value of indefinite-lived intangible assets. If the qualitative assessment indicates that it is more likely than not that indefinite-lived intangible assets are impaired, then a quantitative assessment is required. If the fair value of the indefinite-lived intangible asset exceeds the carrying value, the asset is not impaired. If the fair value of the indefinite-lived intangible asset is less than its carrying value, the asset is impaired and the excess of the asset’s carrying value over the fair value is recognized as an impairment charge. Long-lived assets, other than goodwill and indefinite-lived intangible assets, are tested for impairment whenever events or circumstances indicate that their carrying amount may not be recoverable. If the carrying value of the asset cannot be recovered from estimated future cash flows, undiscounted and without interest, the fair value of the asset is calculated using the present value of estimated net future cash flows. If the carrying amount of the asset exceeds its fair value, an impairment is recorded. Impairment charges, if any, are recorded in general and administrative expenses on the consolidated statements of operations. Litigation - The Company is a party to certain legal and regulatory proceedings with respect to a variety of matters. The Company evaluates the likelihood of an unfavorable outcome of all legal or regulatory proceedings to which it is a party and accrues a loss contingency when the loss is probable and reasonably estimable. Loss contingencies are recorded in provision for litigation on the consolidated statements of operations. These judgments are subjective based on the status of the legal or regulatory proceedings, the merits of its defenses and consultation with in-house and external legal counsel. Legal costs are expensed as incurred and recorded in general and administrative expenses on the consolidated statements of operations. Settlement and other risk management - Mastercard’s rules guarantee the settlement of many of the payment network transactions between its customers. Settlement exposure is the outstanding settlement risk to customers under Mastercard’s rules due to the difference in timing between the payment transaction date and subsequent settlement. For those transactions the Company guarantees, the guarantee will cover the full amount of the settlement obligation to the extent the settlement obligation is not otherwise satisfied. The duration of the settlement exposure is short-term and generally limited to a few days. The Company also enters into agreements in the ordinary course of business under which the Company agrees to indemnify third parties against damages, losses and expenses incurred in connection with legal and other proceedings arising from relationships or transactions with the Company. As the extent of the Company’s obligations under these agreements depends entirely upon the occurrence of future events, the Company’s potential future liability under these agreements is not determinable. The Company accounts for each of its guarantees by recording the guarantee at its fair value at the inception or modification date through earnings. Settlement assets/obligations - The Company operates systems for settling payment transactions among participants in the payments ecosystem in which the Company operates. Settlement is generally completed on a same-day basis. In some circumstances, however, funds may not settle until subsequent business days. In addition, the Company may receive or post funds in advance of transactions related to certain payments capabilities. The Company classifies the balances arising from these various activities as settlement assets and settlement obligations. Income taxes - The Company follows an asset and liability based approach in accounting for income taxes as required under GAAP. Deferred income tax assets and liabilities are recorded to reflect the tax consequences on future years of temporary differences between the financial statement carrying amounts and income tax bases of assets and liabilities. Deferred income taxes are displayed separately as noncurrent assets and liabilities on the consolidated balance sheets. Valuation allowances are provided against assets which are not more likely than not to be realized. The Company recognizes all material tax positions, including uncertain tax positions in which it is more likely than not that the position will be sustained based on its technical merits and if challenged by the relevant taxing authorities. At each balance sheet date, unresolved uncertain tax positions are reassessed to determine whether subsequent developments require a change in the amount of recognized tax benefit. The allowance for uncertain tax positions is recorded in other current and noncurrent liabilities on the consolidated balance sheets. The Company records interest expense related to income tax matters as interest expense on the consolidated statements of operations. The Company includes penalties related to income tax matters in the income tax provision. Cash and cash equivalents - Cash and cash equivalents include certain investments with daily liquidity and with an original maturity of three months or less from the date of purchase. Cash equivalents are recorded at cost, which approximates fair value. Restricted cash and restricted cash equivalents - The Company classifies cash and cash equivalents as restricted when it is unavailable for withdrawal or use in its general operations. The Company has the following types of restricted cash and restricted cash equivalents (“restricted cash”) that are included in the reconciliation of beginning-of-period and end-of-period amounts shown on the consolidated statements of cash flows: • Restricted cash - Restricted cash includes cash segregated to meet regulatory commitments, cash within qualified legal settlement funds and cash restricted for other general business purposes, including contractually restricted deposits as well as cash balances that are restricted based on the Company’s intention with regard to usage. • Restricted security deposits held for customers - The Company requires certain customers to enter into risk mitigation arrangements, including cash collateral and/or forms of credit enhancement such as letters of credit and guarantees, for settlement of their transactions. Certain risk mitigation arrangements for settlement, such as standby letters of credit and bank guarantees, are not recorded on the consolidated balance sheets. The Company also holds cash deposits and certificates of deposit from certain customers as collateral for settlement of their transactions, which are recorded as assets on the consolidated balance sheets. These assets are fully offset by corresponding liabilities included on the consolidated balance sheets. The amount of these security deposits and the duration held are determined by the risk profile of the individual customer and the Company’s risk management practices. Fair value - The Company measures certain financial assets and liabilities at fair value on a recurring basis by estimating the price that would be received upon the sale of an asset or paid to transfer a liability in an orderly transaction between market participants. The Company also measures certain financial and non-financial assets and liabilities at fair value on a nonrecurring basis, when a change in fair value or impairment is evidenced. The Company classifies these recurring and nonrecurring fair value measurements into a three-level hierarchy (“Valuation Hierarchy”). The Valuation Hierarchy is based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date. A financial instrument’s categorization within the Valuation Hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The three levels of the Valuation Hierarchy are as follows: • Level 1 - inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities in active markets. • Level 2 - inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in inactive markets and inputs that are observable for the asset or liability. • Level 3 - inputs to the valuation methodology are unobservable and cannot be directly corroborated by observable market data. The Company’s financial assets and liabilities measured at fair value on a recurring basis include investment securities available-for-sale, marketable securities, derivative instruments and deferred compensation. The Company’s financial assets measured at fair value on a nonrecurring basis include nonmarketable securities. The Company’s non-financial assets measured at fair value on a nonrecurring basis include property, equipment and right-of-use assets, goodwill and other intangible assets and are subject to fair value adjustments in certain circumstances, such as when there is evidence of impairment. Investment securities - The Company classifies investments as available-for-sale or held-to-maturity at the date of acquisition. • Available-for-sale debt securities: ◦ Investments in debt securities that are available to meet the Company’s current operational needs are classified as current assets and the securities that are not available for current operational needs are classified as noncurrent assets on the consolidated balance sheets. The debt securities are carried at fair value, with unrealized gains and losses, net of tax, recorded as a separate component of accumulated other comprehensive income (loss) on the consolidated statements of changes in equity. Net realized gains and losses on debt securities are recognized in investment income on the consolidated statements of operations. The specific identification method is used to determine realized gains and losses. The Company evaluates its debt securities for impairment on an ongoing basis. When there has been a decline in fair value of a debt security below the amortized cost basis, the Company recognizes an impairment if: (1) it has the intent to sell the security; (2) it is more likely than not that it will be required to sell the security before recovery of the amortized cost basis; or (3) it does not expect to recover the entire amortized cost basis of the security. The credit loss component of the impairment is recognized as an allowance and recorded in other income (expense), net on the consolidated statements of operations while the non-credit related loss remains in accumulated other comprehensive income (loss) until realized from a sale or subsequent impairment. • Held-to-maturity securities: ◦ Time deposits - The Company classifies time deposits with original maturities greater than three months as held-to-maturity. Held-to-maturity securities that mature within one year are classified as current assets within investments on the consolidated balance sheets while held-to-maturity securities with maturities of greater than one year are classified as other assets. Time deposits are carried at amortized cost on the consolidated balance sheets and are intended to be held until maturity. Equity investments - The Company holds equity securities of publicly traded and privately held companies. • Marketable equity securities - Marketable equity securities are strategic investments in publicly traded companies and are measured at fair value using quoted prices in their respective active markets with changes recorded through gains (losses) on equity investments, net on the consolidated statements of operations. Marketable equity securities that are expected to be held as part of the Company’s long-term investment strategy are classified in other assets on the consolidated balance sheets. • Nonmarketable equity investments - The Company’s nonmarketable equity investments, which are reported in other assets on the consolidated balance sheets, include strategic investments in privately held companies without readily determinable market values. The Company uses discounted cash flows and market assumptions to estimate the fair value of its nonmarketable equity investments when certain events or circumstances indicate that impairment may exist. The Company’s nonmarketable equity investments are accounted for under the measurement alternative method or equity method. ◦ Measurement alternative method - The Company accounts for investments in common stock or in-substance common stock under the measurement alternative method of accounting when it does not exercise significant influence, generally when it holds less than 20% ownership in the entity or when the interest in a limited partnership or limited liability company is less than 5% and the Company has no significant influence over the operations of the investee. Investments in companies that Mastercard does not control, but that are not in the form of common stock or in-substance common stock, are also accounted for under the measurement alternative method of accounting. Measurement alternative investments are measured at cost, less any impairment and adjusted for changes resulting from observable price changes in orderly transactions for identical or similar investments of the same issuer. Fair value adjustments, as well as impairments, are included in gains (losses) on equity investments, net on the consolidated statements of operations. ◦ Equity method - The Company accounts for investments in common stock or in-substance common stock under the equity method of accounting when it has the ability to exercise significant influence over the operations of the investee, generally when it holds between 20% and 50% ownership in the entity. The excess of the cost over the underlying net equity of investments accounted for under the equity method is allocated to identifiable tangible and intangible assets and liabilities based on fair values at the date of acquisition. The amortization of the excess of the cost over the underlying net equity of investments and Mastercard’s share of net earnings or losses of entities accounted for under the equity method of accounting is included in other income (expense), net on the consolidated statements of operations. In addition, investments in flow-through entities such as limited partnerships and limited liability companies are also accounted for under the equity method when the Company has the ability to exercise significant influence over the operations of the investee, generally when the investment ownership percentage is equal to or greater than 5% of the outstanding ownership interest. The Company’s share of net earnings or losses for these investments are included in gains (losses) on equity investments, net on the consolidated statements of operations. Derivative and hedging instruments - The Company’s derivative financial instruments are recorded as either assets or liabilities on the balance sheet and measured at fair value. The Company’s foreign exchange and interest rate derivative contracts are included in Level 2 of the Valuation Hierarchy as the fair value of the contracts are based on inputs that are observable based on broker quotes for the same or similar instruments. The Company does not enter into derivative instruments for trading or speculative purposes. For derivatives that are not designated as hedging instruments, realized and unrealized gains and losses from the change in fair value of the derivatives are recognized in current earnings. The Company’s derivatives that are designated as hedging instruments are required to meet established accounting criteria. In addition, an effectiveness assessment is required to demonstrate that the derivative is expected to be highly effective at offsetting changes in fair value or cash flows of the underlying exposure both at inception of the hedging relationship and on an ongoing basis. The method of assessing hedge effectiveness and measuring hedge results is formally documented at hedge inception and assessed at least quarterly throughout the designated hedge period. The Company may designate derivative instruments as cash flow, fair value and net investment hedges, as follows: • Cash flow hedges - Fair value adjustments to derivative instruments are recorded, net of tax, in other comprehensive income (loss) on the consolidated statements of comprehensive income. Any gains and losses deferred in accumulated other comprehensive income (loss) are subsequently reclassified to the corresponding line item on the consolidated statements of operations when the underlying hedged transactions impact earnings. For hedges that are no longer deemed highly effective, hedge accounting is discontinued prospectively, and any gains and losses remaining in accumulated other comprehensive income (loss) are reclassified to earnings when the underlying forecasted transaction occurs. Any amounts excluded from effectiveness testing of cash flow hedges are recognized in earnings over the life of the hedging instrument. If it is probable that the forecasted transaction will no longer occur, the associated gains or losses in accumulated other comprehensive income (loss) are reclassified to the corresponding line item on the consolidated statements of operations in current earnings. • Fair value hedges - Changes in the fair value of derivative instruments are recorded in current-period earnings, along with the gain or loss on the hedged asset or liability (“hedged item”) that is attributable to the hedged risk. All amounts recognized in earnings are recorded to the corresponding line item on the consolidated statements of operations as the earnings effect of the hedged item. Hedged items are measured on the consolidated balance sheets at their carrying amount adjusted for any changes in fair value attributable to the hedged risk (“basis adjustments”). The Company defers the amortization of any basis adjustments until the end of the derivative instrument’s term. If the hedge designation is discontinued for reasons other than derecognition of the hedged item, the remaining basis adjustments are amortized in accordance with applicable GAAP for the hedged item. • Net investment hedges - The Company has numerous investments in foreign subsidiaries. The net assets of these subsidiaries are exposed to volatility in foreign currency exchange rates. The Company may use foreign currency denominated debt and/or derivative instruments to hedge a portion of its net investment in foreign operations against adverse movements in exchange rates. The effective portion of the foreign currency gains and losses related to the hedging instruments are reported in accumulated other comprehensive income (loss) on the consolidated balance sheets as a cumulative translation adjustment component of equity. Gains and losses in accumulated other comprehensive income (loss) are reclassified to earnings only if the Company sells or substantially liquidates its net investments in foreign subsidiaries. Amounts excluded from effectiveness testing of net investment hedges are recognized in earnings over the life of the hedging instrument. The Company evaluates the effectiveness of the net investment hedge each quarter. Property, equipment and right-of-use assets - Property and equipment are stated at cost less accumulated depreciation and amortization. Depreciation and amortization is computed using the straight-line method over the estimated useful lives of the assets. Depreciation of leasehold improvements and amortization of finance leases is included in depreciation and amortization expense on the consolidated statements of operations. Operating lease amortization expense is included in g |
