Accounting Policies [Abstract] |
Principles of Consolidation | PRINCIPLES OF CONSOLIDATION The Consolidated Financial Statements are prepared in conformity with accounting principles generally accepted in the United States of America (GAAP). Significant intercompany transactions are eliminated. We consolidate entities in which we hold a “controlling financial interest.” For voting interest entities, we are considered to hold a controlling financial interest when we are able to exercise control over the investees’ operating and financial decisions. For variable interest entities (VIEs), the determination of which is based on the amount and characteristics of the entity’s equity, we are considered to hold a controlling financial interest when we are determined to be the primary beneficiary. A primary beneficiary is the party that has both: (1) the power to direct the activities that most significantly impact that VIE’s economic performance, and (2) the obligation to absorb the losses of, or the right to receive the benefits from, the VIE that could potentially be significant to that VIE. Entities in which our voting interest in common equity does not provide it with control, but allows us to exert significant influence over operating and financial decisions, are accounted for under the equity method. We also have investments in equity securities where our voting interest is below the level of significant influence, including investments that we make in non-public companies in the ordinary course of business. Such investments are initially recorded at cost and adjusted to fair value through earnings for observable price changes in orderly transactions for identical or similar instruments of the same company or if they are determined to be impaired. See Note 4 for the accounting policy for our marketable equity securities.
Foreign Currency | FOREIGN CURRENCY Transactions conducted in currencies other than the applicable functional currency of an entity are converted to the functional currency at the exchange rate on the transaction date. At the period end, monetary assets and liabilities are remeasured to the functional currency using period end rates. The resulting transaction gains and losses are recorded in Other, net expenses in the Consolidated Statements of Income. For subsidiaries where the functional currency is not the U.S. dollar, the monetary assets and liabilities and results of operations are translated for consolidation purposes into U.S. dollars at period-end rates for monetary assets and liabilities and generally at average rates for results of operations. The resulting translation adjustments, along with any related qualifying hedge and tax effects, are included in accumulated other comprehensive income (loss) (AOCI), a component of shareholders’ equity. Translation adjustments, including qualifying hedge and tax effects, are reclassified to earnings upon the sale or substantial liquidation of investments in foreign operations.
Amounts Based on Estimates and Assumptions | AMOUNTS BASED ON ESTIMATES AND ASSUMPTIONS Accounting estimates are an integral part of the Consolidated Financial Statements. These estimates are based, in part, on management’s assumptions concerning future events. Among the more significant assumptions are those that relate to reserves for Card Member credit losses on loans and receivables, Membership Rewards liability, goodwill and income taxes. These accounting estimates reflect the best judgment of management, but actual results could differ.
Revenue | Revenue is recognized when obligations under the terms of a contract with our customers are satisfied. We are not required to disclose revenue that is expected to be recognized in future periods related to contracts that have an original expected duration of one year or less and contracts with variable consideration (e.g., discount revenue). Non-interest revenue expected to be recognized in future periods related to all other contracts with customers is not material. Discount Revenue Discount revenue represents the amount we earn and retain from the merchant payable for facilitating transactions between Card Members and merchants on payment products issued by American Express. The amount of fees charged for accepting our cards as payment, or merchant discount, varies with, among other factors, the industry in which the merchant conducts business, the merchant’s overall American Express-related transaction volume, the method of payment, the settlement terms with the merchant, the method of submission of transactions and, in certain instances, the geographic scope of the card acceptance agreement between the merchant and us (e.g., local or global) and the transaction amount. Discount revenue is generally recorded at the time the Card Member transaction occurs. Card acceptance agreements, which include the agreed-upon terms for charging the merchant discount fee, vary in duration. Our contracts with small- and mid-sized merchants generally have no fixed contractual duration, while those with large merchants are generally for fixed periods, which typically range from three to seven years in duration. Our fixed-period agreements may include auto-renewal features, which may allow the existing terms to continue beyond the stated expiration date until a new agreement is reached. We satisfy our obligations under these agreements over the contract term, often on a daily basis, including through the processing of Card Member transactions and the availability of our payment network. In cases where the merchant acquirer is a third party, we receive a network rate fee in our settlement with the merchant acquirer, which is negotiated between us and that merchant acquirer and is recorded as discount revenue at the time the Card Member transaction occurs. Net Card Fees Net card fees represent revenue earned from annual card membership fees, which vary based on the type of card and the number of cards for each account. These fees, net of acquisition costs and a reserve for projected refunds for Card Member cancellations, are deferred and recognized on a straight-line basis over the twelve-month card membership period as Net card fees in the Consolidated Statements of Income and are therefore more stable in relation to short term business or economic shifts. The unamortized net card fee balance is reported in Other liabilities on the Consolidated Balance Sheets. Service Fees and Other Revenue Service fees and other revenue includes service fees earned from merchants and other customers and travel commissions and fees, which are generally recognized in the period when the service is performed, and delinquency and foreign currency-related fees, which are primarily recognized in the period when they are charged to the Card Member. In addition, Service fees and other revenue includes income (losses) from our investments in which we have significant influence and therefore account for under the equity method. Refer to Note 18 for additional information. Processed Revenue Processed revenue primarily represents revenues related to network partnership agreements, comprising royalties, fees and amounts earned for facilitating transactions on cards issued by network partners. In our role as the operator of the American Express network, we settle with merchants and our third-party merchant acquirers on behalf of our network card issuing partners. The amount of fees charged for accepting American Express-branded cards is generally deducted from the payment to the merchant or third-party merchant acquirer and recorded as Processed revenue at the time the Card Member transaction occurs. Our network card issuing partners receive an issuer rate that is individually negotiated between that issuer and us and is recorded as contra-revenue within Processed revenue to the extent that there is revenue from the same customer, after which any additional issuer rate is recorded as expense in Business development. Processed revenue also includes fees related to alternative payment solutions, which are generally recognized when the service is performed. Contra-revenue Payments made pursuant to contractual arrangements with our merchants, network partners and other customers are classified as contra-revenue, except where we receive goods, services or other benefits for which the fair value is determinable and measurable, in which case they are recorded as expense. Interest Income Interest on Card Member loans is assessed using the average daily balance method. Unless the loan is classified as non-accrual, interest is recognized based upon the principal amount outstanding, in accordance with the terms of the applicable account agreement, until the outstanding balance is paid, or written off. Interest and dividends on investment securities primarily relate to our performing fixed-income securities. Interest income is recognized as earned using the effective interest method, which adjusts the yield for security premiums and discounts, fees and other payments, so that a constant rate of return is recognized on the investment security’s outstanding balance. Amounts are recognized until securities are in default or when it becomes likely that future interest payments will not be made as scheduled. Interest on deposits with banks and other is recognized as earned, and primarily relates to the placement of cash, in excess of near-term funding requirements, in interest-bearing time deposits, overnight sweep accounts, and other interest-bearing demand and call accounts.
Interest Expense | Interest Expense Interest expense includes interest incurred primarily to fund Card Member loans and receivables, general corporate purposes and liquidity needs, and is recognized as incurred. Interest expense is divided principally into two categories: (i) deposits, which primarily relates to interest expense on deposits taken from customers and institutions and (ii) debt, which primarily relates to interest expense on our long-term debt and short-term borrowings, as well as the realized impact of derivatives used to hedge interest rate risk on our long-term debt.
Expenses | Card Member Rewards We issue credit, charge and debit cards that allow Card Members to participate in various rewards programs (e.g., Membership Rewards, cash back and cobrand). Rewards expense is recognized in the period Card Members earn rewards, generally by spending on their enrolled card products. For Membership Rewards and cash back, we record a liability that represents the rewards that are expected to be redeemed, as well as, for Membership Rewards, the estimated cost of points earned. For cobrand, we record a liability based primarily on rewards earned on Card Member spending on cobrand cards, and make associated payments to our cobrand partners. The partner is liable for providing rewards to the Card Member under the cobrand partner’s own loyalty program. Card Member rewards liabilities are impacted over time by enrollment levels, attrition, the volume of points earned and redeemed, and the associated redemption costs. Changes in the Card Member rewards liabilities during the period are taken as an increase or decrease to the Card Member rewards expense in the Consolidated Statements of Income. Business Development Business development expense includes payments to our cobrand partners, corporate client incentive payments earned on achievement of pre-set targets and certain payments to network partners. These costs are generally expensed as incurred. Card Member Services Card Member services expense represents costs incurred in providing our Card Members with various value-added benefits and services, which are generally expensed as incurred. Marketing Marketing expense includes costs incurred in the development and initial placement of advertising, which are expensed in the period in which the advertising first takes place. All other marketing expenses are generally expensed as incurred.
Cash and Cash Equivalents | Cash and Cash Equivalents Cash and cash equivalents include cash and amounts due from banks, interest-bearing bank balances, including securities purchased under resale agreements, restricted cash, and other highly liquid investments with original maturities of 90 days or less. Restricted cash primarily represents amounts related to Card Member credit balances as well as upcoming debt maturities of consolidated VIEs.
Goodwill | Goodwill Goodwill represents the excess of the acquisition cost of an acquired business over the fair value of assets acquired and liabilities assumed. We allocate goodwill to our reporting units for the purpose of impairment testing. A reporting unit is defined as an operating segment, or a business that is one level below an operating segment, for which discrete financial information is regularly reviewed by the operating segment manager. Prior to completing the annual assessment of goodwill for impairment, we perform a recoverability test of certain long-lived assets. We have historically evaluated goodwill for impairment annually as of June 30, or more frequently if events occur or circumstances change that would more likely than not reduce the fair value of one or more of our reporting units below its carrying value. In the fourth quarter of 2023, we changed our annual impairment assessment date to November 1 for all reporting units. The change in the annual testing date for goodwill impairment is considered a change in accounting principle, which we believe is preferable as the new date better aligns with our long-term planning and forecasting process. We have determined that it is impracticable to objectively determine projected cash flows and related valuation estimates that would have been used as of each November 1 of the prior reporting periods without the use of hindsight. As such, we prospectively applied the change in annual goodwill impairment testing date beginning November 1, 2023. The change in assessment date did not delay, accelerate or avoid a potential impairment charge. We have the option to perform a qualitative assessment of goodwill impairment to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. Alternatively, we can perform a more detailed quantitative assessment of goodwill impairment. This qualitative assessment entails the evaluation of factors such as economic conditions, industry and market considerations, cost factors, overall financial performance of the reporting unit and other company and reporting unit-specific events. If we determine that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, we then perform the impairment evaluation using the quantitative assessment. The quantitative assessment compares the fair value of a reporting unit with its carrying amount, including goodwill. If the carrying amount exceeds the reporting unit’s fair value, an impairment loss is recognized for the amount over and above the reporting unit’s fair value. When measuring the fair value of our reporting units in the quantitative assessment, we use widely accepted valuation techniques, applying a combination of the income approach (discounted cash flows) and market approach (market multiples). When preparing discounted cash flow models under the income approach, we use internal forecasts to estimate future cash flows expected to be generated by the reporting units. To discount these cash flows, we use the expected cost of equity, determined by using a capital asset pricing model. We believe the discount rates appropriately reflect the risks and uncertainties in the financial markets generally and specifically in our internally-developed forecasts. When using market multiples under the market approach, we apply comparable publicly traded companies’ multiples (e.g., earnings or revenues) to our reporting units’ operating results. During the year ended December 31, 2023, we performed assessments for each reporting unit in connection with our annual goodwill impairment evaluation as of both June 30, 2023 and November 1, 2023, in accordance with the change in goodwill impairment testing date. As of both testing dates, we determined that it was more likely than not that the fair values of each of our reporting units exceeded their carrying values and accordingly no impairment was recognized. In addition, during the year ended December 31, 2022, we performed a quantitative goodwill impairment assessment for those reporting units which were impacted by the realignment of our operating segments and concluded that their fair values exceeded their carrying values. OTHER INTANGIBLE ASSETS Intangible assets are amortized on a straight-line basis over their estimated useful lives of 1 to 22 years. We review long-lived assets and asset groups, including intangible assets, for impairment whenever events and circumstances indicate their carrying amounts may not be recoverable. An impairment is recognized if the carrying amount is not recoverable and exceeds the asset or asset group’s fair value.
Premises and Equipment | Premises and Equipment Premises and equipment, including leasehold improvements, are carried at cost less accumulated depreciation. Costs incurred during construction are capitalized and are depreciated once an asset is placed in service. Depreciation is generally computed using the straight-line method over the estimated useful lives of the assets, which range from 3 to 10 years for equipment, furniture and building improvements, and from 40 to 50 years for premises, which are depreciated based upon their estimated useful life at the acquisition date. Certain costs associated with the acquisition or development of internal-use software are also capitalized and recorded in Premises and equipment. Once the specific software feature is ready for its intended use, these costs are amortized on a straight-line basis over the software’s estimated useful life, generally 5 years. We review these assets for impairment using the same impairment methodology used for our intangible assets. Leasehold improvements are depreciated using the straight-line method over the lesser of the remaining term of the leased facility, or the economic life of the improvement, and range from 5 to 10 years. We recognize lease restoration obligations at the fair value of the restoration liabilities when incurred and amortize the restoration assets over the lease term.
Leases | Leases We have operating leases worldwide for facilities and equipment, which, for those leases with terms greater than 12 months, are recorded as lease-related assets and liabilities. We do not separate lease and non-lease components. Lease-related assets, or right-of-use assets, are recognized at the lease commencement date at amounts equal to the respective lease liabilities, adjusted for prepaid lease payments, initial direct costs and lease incentives. Lease liabilities are recognized at the present value of the contractual fixed lease payments, discounted using our incremental borrowing rate as of the lease commencement date or upon modification of the lease. Operating lease expense is recognized on a straight-line basis over the lease term, while variable lease payments are expensed as incurred.
Classification of Various Items | CLASSIFICATION OF VARIOUS ITEMS Certain reclassifications of prior period amounts have been made to conform to the current period presentation.
Recently Adopted and Issued Accounting Standards | RECENTLY ADOPTED AND ISSUED ACCOUNTING STANDARDS Effective January 1, 2023, we adopted new accounting guidance on troubled debt restructurings (TDR) and vintage disclosures on a prospective basis. The new guidance eliminated the existing TDR guidance for those entities that have adopted ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, created a single loan modification accounting model and enhanced disclosure requirements for loan modifications and write-offs. The implementation did not have a material impact to our Consolidated Financial Statements. Refer to Note 2 for further information, including the enhanced disclosures. In March 2023, the Financial Accounting Standards Board issued updated accounting guidance to allow the proportional amortization method (PAM) to be applied to tax credit structures beyond low-income housing tax credit (LIHTC) investments. Having implemented PAM in relation to LIHTC investments in January 2021, we early adopted the updated guidance with respect to other qualifying investments in the fourth quarter of 2023. The impact of this change is immaterial to our Consolidated Financial Statements, therefore we implemented the updated guidance on a prospective basis. In November 2023, the Financial Accounting Standards Board issued updated accounting guidance for Segment Reporting, effective January 1, 2024, with early adoption permitted. The updated guidance requires enhanced disclosures for significant expenses by reportable operating segment. Significant expense categories and amounts are those regularly provided to the chief operating decision maker (CODM) and included in the measure of a segment’s profit or loss. The updated guidance will also require us to disclose the title and position of our CODM, including an explanation of how our CODM uses the reported measure(s) of segment profit or loss in assessing segment performance and deciding how to allocate resources. We plan to adopt the new standard for the annual reporting period beginning January 1, 2024, and for interim periods beginning January 1, 2025. The updated guidance is not expected to have a material impact to our Consolidated Financial Statements. In December 2023, the Financial Accounting Standards Board issued updated accounting guidance on Disclosures for Income Taxes, effective January 1, 2025, with early adoption permitted. The updated guidance requires additional disclosure and disaggregated information in the Income Tax Rate reconciliation using both percentages and reporting currency amounts, with additional qualitative explanations of individually significant reconciling items. The updated guidance also requires disclosure of the amount of income taxes paid (net of refunds received) disaggregated by jurisdictional categories (federal (national), state and foreign). We are currently assessing the updated guidance, however it is not expected to have a material impact to our Consolidated Financial Statements.
Card Member and Other Loans, Card Member Receivables and Reserve for Credit Losses | CARD MEMBER AND OTHER LOANS Card Member loans are generally recorded at the time a Card Member enters into a point-of-sale transaction with a merchant and represent revolve-eligible transactions on our card products, as well as any finance charges and associated card-related fees. Card Members with outstanding revolving loans are required to make a minimum monthly payment, and the balances that Card Members choose to revolve are subject to finance charges. These loans have varying terms such as credit limits, interest rates, fees and payment structures, which can be revised over time based on new information about Card Members and in accordance with applicable regulations and the respective product’s terms and conditions. Card Member loans are presented on the Consolidated Balance Sheets net of reserves for credit losses (refer to Note 3), and include principal and any related accrued interest and fees. Our policy generally is to cease accruing interest on a Card Member loan at the time the account is written off, and establish reserves for interest that we believe will not be collected. Other loans are recorded at the time any extension of credit is provided to consumer and commercial customers for non-card financing products. These loans have a range of fixed terms such as interest rates, fees and repayment periods. Borrowers are typically required to make pre-established monthly payments over the term of the loan. Non-card financing products are not associated with a Card Member agreement, and instead are governed by a separate borrowing relationship. Other loans are presented on the Consolidated Balance Sheets net of reserves for credit losses and include principal and any related accrued interest and fees. CARD MEMBER RECEIVABLES Card Member receivables are recorded at the time a Card Member enters into a point-of-sale transaction with a merchant and represent amounts due on our card products and card-related fees that need to be paid in full on or before the Card Member’s payment due date. Charge Card Members generally must pay the full amount billed each month. Card Member receivable balances are presented on the Consolidated Balance Sheets net of reserves for credit losses (refer to Note 3), and include principal and any related accrued fees. Reserves for credit losses represent our best estimate of the expected credit losses in our outstanding portfolio of Card Member loans and receivables as of the balance sheet date. The CECL methodology requires us to estimate lifetime expected credit losses by incorporating historical loss experience, as well as current and future economic conditions over a reasonable and supportable period (R&S Period), which is approximately three years, beyond the balance sheet date. We make various judgments combined with historical loss experience to determine a reserve rate that is applied to the outstanding loan or receivable balance to produce a reserve for expected credit losses. We use a combination of statistically-based models that incorporate current and future economic conditions throughout the R&S Period. The process of estimating expected credit losses is based on several key models: Probability of Default (PD), Exposure at Default (EAD) and future recoveries for each month of the R&S Period. Beyond the R&S Period, we estimate expected credit losses by immediately reverting to long-term average loss rates. •PD models are used to estimate the likelihood an account will be written-off. •EAD models are used to estimate the balance of an account at the time of write-off. This includes balances less expected repayments based on historical payment and revolve behavior, which vary by customer. Due to the nature of revolving loan portfolios, the EAD models are complex and involve assumptions regarding the relationship between future spend and payment behaviors. •Recovery models are used to estimate amounts that are expected to be received from Card Members after default occurs, typically as a result of collection efforts. Future recoveries are estimated taking into consideration the time of default, time elapsed since default and macroeconomic conditions. We also estimate the likelihood and magnitude of recovery of previously written off accounts considering how long ago the account was written off and future economic conditions, even if such expected recoveries exceed expected losses. Our models are developed using historical loss experience covering the economic cycle and consider the impact of account characteristics on expected losses. This history includes the performance of loans and receivables modifications for borrowers experiencing financial difficulty, including their subsequent defaults. Future economic conditions that are incorporated over the R&S Period include multiple macroeconomic scenarios provided to us by an independent third party. Management reviews these economic scenarios each period and assigns probability weights to each scenario, generally with a consistent initial distribution. At times, due to macroeconomic uncertainty and volatility, management may apply judgment and assign different probability weights to scenarios. These macroeconomic scenarios contain certain variables, including unemployment rates and real gross domestic product (GDP), that are significant to our models. We also evaluate whether to include qualitative reserves to cover losses that are expected but, in our assessment, may not be adequately represented in the quantitative methods or the economic assumptions. We consider whether to adjust the quantitative reserves (higher or lower) to address possible limitations within the models or factors not included within the models, such as external conditions, emerging portfolio trends, the nature and size of the portfolio, portfolio concentrations, the volume and severity of past due accounts, or management risk actions. Lifetime losses for most of our loans and receivables are evaluated at an appropriate level of granularity, including assessment on a pooled basis where financial assets share similar risk characteristics, such as past spend and remittance behaviors, credit bureau scores where available, delinquency status, tenure of balance outstanding, amongst others. Credit losses on accrued interest are measured and presented as part of Reserves for credit losses on the Consolidated Balance Sheets and within the Provisions for credit losses in the Consolidated Statements of Income, rather than reversing interest income. Separate models are used for accounts deemed a troubled debt restructuring, which are measured individually and incorporate a discounted cash flow model. See Note 2 for information on TDRs. Loans and receivable balances are written off when we consider amounts to be uncollectible, which is generally determined by the number of days past due and is typically no later than 180 days past due for pay in full or revolving loans and 120 days past due for term loans. Loans and receivables in bankruptcy or owed by deceased individuals are generally written off upon notification.
Investment Securities | Investment securities principally include available-for-sale debt securities carried at fair value on the Consolidated Balance Sheets. The methodology for estimating credit losses for available for sale debt securities requires us to estimate lifetime credit losses for all available-for-sale debt securities in an unrealized loss position. When estimating a security’s probability of default and the recovery rate, we assess the security’s credit indicators, including credit ratings. If our assessment indicates that an estimated credit loss exists, we determine the portion of the unrealized loss attributable to credit deterioration and record a reserve for the estimated credit loss through the Consolidated Statements of Income in Other loans Provision for credit losses. Unrealized gains and any portion of a security’s unrealized loss attributable to non-credit losses are recorded in the Consolidated Statements of Comprehensive Income, net of tax.
Asset Securitizations | We periodically securitize Card Member loans and receivables arising from our card businesses through the transfer of those assets to securitization trusts, American Express Credit Account Master Trust (the Lending Trust) and American Express Issuance Trust II (the Charge Trust and together with the Lending Trust, the Trusts). The Trusts then issue debt securities collateralized by the transferred assets to third-party investors. The Trusts are considered VIEs as they have insufficient equity at risk to finance their activities, which are to issue debt securities that are collateralized by the underlying Card Member loans and receivables. Refer to Note 1 for further details on the principles of consolidation. We perform the servicing and key decision making for the Trusts, and therefore have the power to direct the activities that most significantly impact the Trusts’ economic performance, which are the collection of the underlying Card Member loans and receivables. In addition, we hold all of the variable interests in both Trusts, with the exception of the debt securities issued to third-party investors. Our ownership of variable interests in the Lending Trust was $15.3 billion and $16.0 billion as of December 31, 2023 and 2022, respectively, and in the Charge Trust was $4.6 billion and $5.2 billion as of December 31, 2023 and 2022, respectively. These variable interests held by us provide us with the right to receive benefits and the obligation to absorb losses, which could be significant to both the Lending Trust and the Charge Trust. Based on these considerations, we are the primary beneficiary of the Trusts and therefore consolidate the Trusts. The debt securities issued by the Trusts are non-recourse to us. The securitized Card Member loans and receivables held by the Lending Trust and the Charge Trust, respectively, are available only for payment of the debt securities or other obligations issued or arising in the securitization transactions (refer to Note 2). The long-term debt of each Trust is payable only out of collections on their respective underlying securitized assets (refer to Note 8).
Other Assets | We account for such tax credit investments using the Proportional Amortization Method, which we elected to implement prospectively on January 1, 2021 for LIHTC investments and in the fourth quarter of 2023 for other qualifying investments.
Membership Rewards | MEMBERSHIP REWARDS The Membership Rewards program allows enrolled Card Members to earn points that can be redeemed for a broad variety of rewards including, but not limited to, travel, shopping, gift cards, and covering eligible charges. We record a Membership Rewards liability that represents our best estimate of the cost of points earned that are expected to be redeemed by Card Members in the future. The weighted average cost (WAC) per point and the Ultimate Redemption Rate (URR) are the key assumptions used to estimate the liability. We use statistical and actuarial models to estimate the URR based on redemption trends, card product type, enrollment tenure, card spend levels and credit attributes. The WAC per point assumption is derived from 12 months of redemptions and is adjusted as appropriate for certain changes in redemption costs that are not representative of future cost expectations and expected developments in redemption patterns. The expense for Membership Rewards points is included in Card Member rewards expense. We periodically evaluate our liability estimation process and assumptions based on changes in cost per point redeemed, partner contract changes and developments in redemption patterns, which may be impacted by product refreshes, changes in redemption options and mix of proprietary cards-in-force.
Stock-based Compensation | Stock-based compensation expense is generally recognized ratably based on the grant-date fair value of the awards, net of expected forfeitures, over the vesting period. Generally, the vesting period is the time from the grant date to the earlier of the vesting date defined in each award agreement or the date the colleague will become eligible to retire. Retirement eligibility is dependent upon age and/or years of service. RSUs containing only service conditions generally vest ratably over three years, or four years for awards granted prior to 2022, beginning with the first anniversary of the grant date. RSUs containing both service and performance conditions generally vest on the third anniversary of the grant date, and the number of shares earned generally ranges from zero to 120 percent of target depending on the achievement of predetermined Company metrics. RSU holders receive dividend equivalents or dividends.Other incentive awards can be settled with cash or equity shares at our discretion and final approval from the Compensation and Benefits Committee. These awards are generally settled with cash and thus are classified as liabilities; therefore, the fair value is determined at the grant date and remeasured quarterly as part of compensation expense over the vesting period.
Retirement Plans | We recognize the funded status of our defined benefit pension plans and other postretirement benefit plans, measured as the difference between the fair value of the plan assets and the projected benefit obligation, on the Consolidated Balance Sheets.
Legal Contingencies | We have accrued for certain of our outstanding legal proceedings. An accrual is recorded when it is both (a) probable that a loss has occurred and (b) the amount of loss can be reasonably estimated. There may be instances in which an exposure to loss exceeds the accrual. We evaluate, on a quarterly basis, developments in legal proceedings that could cause an increase or decrease in the amount of the accrual that has been previously recorded, or a revision to the disclosed estimated range of possible losses, as applicable. For those disclosed legal proceedings where a loss is reasonably possible in future periods, whether in excess of a recorded accrual for legal or tax contingencies, or where there is no such accrual, and for which we are able to estimate a range of possible loss, the current estimated range is zero to $400 million in excess of any accruals related to those matters. This range represents management’s estimate based on currently available information and does not represent our maximum loss exposure; actual results may vary significantly. As such legal proceedings evolve, we may need to increase our range of possible loss or recorded accruals. In addition, it is possible that significantly increased merchant steering or other actions impairing the Card Member experience as a result of an adverse resolution in one or any combination of the disclosed merchant cases could have a material adverse effect on our business and results of operations.
Derivatives and Hedging Activities | A majority of our derivative assets and liabilities as of December 31, 2023 and 2022 are subject to master netting agreements with our derivative counterparties. Accordingly, where appropriate, we have elected to present derivative assets and liabilities with the same counterparty on a net basis in the Consolidated Balance Sheets. Our derivatives are carried at fair value on the Consolidated Balance Sheets. The accounting for changes in fair value depends on the instruments’ intended use and the resulting hedge designation, if any, as discussed below.We formally assess, at inception of the hedge accounting relationship and on a quarterly basis, whether derivatives designated as hedges are highly effective in offsetting the fair value or cash flows of the hedged items. These assessments usually are made through the application of a regression analysis method. If it is determined that a derivative is not highly effective as a hedge, we will discontinue the application of hedge accounting.Gains or losses on the fair value hedging instrument principally offset the losses or gains on the hedged item attributable to the hedged risk.We primarily designate foreign currency derivatives as net investment hedges to reduce our exposure to changes in currency exchange rates on our investments in non-U.S. subsidiaries. We have derivatives that act as economic hedges, but are not designated as such for hedge accounting purposes. Foreign currency transactions from time to time may be partially or fully economically hedged through foreign currency contracts, primarily foreign exchange forwards. These hedges generally mature within one year. Foreign currency contracts involve the purchase and sale of designated currencies at an agreed upon rate for settlement on a specified date. The changes in the fair value of derivatives that are not designated as hedges are intended to offset the related foreign exchange gains or losses of the underlying foreign currency exposures.
Fair Value Measurements | We monitor the market conditions and evaluate the fair value hierarchy levels at least quarterly. We have certain assets that are subject to measurement at fair value on a nonrecurring basis. For these assets, measurement at fair value in periods subsequent to their initial recognition is applicable if they are determined to be impaired or where there are observable price changes for equity investments without readily determinable fair values. We estimate the Level 3 fair value of equity investments without readily determinable fair values, which include investments in our Amex Ventures portfolio, based on price changes as of the date of new similar equity financing transactions completed by the companies in the portfolio. In addition, impairments on such investments are recorded to account for the difference between the estimated fair value and carrying value of an investment based on a qualitative assessment of impairment indicators such as business performance, general market conditions and the economic and regulatory environment. When an impairment triggering event occurs, the fair value measurement is generally derived by taking into account all available information, such as share prices of publicly traded peer companies, internal valuations performed by our investees, and other third-party fair value data. The fair value of impaired investments represents a Level 3 fair value measurement. The carrying value of equity investments without readily determinable fair values totaled $0.9 billion and $1.0 billion as of December 31, 2023 and 2022, respectively, of which approximately nil and $0.6 billion as of December 31, 2023 and 2022, respectively, represented a nonrecurring Level 3 fair value measurement for certain of our equity investments. These amounts are included within Other assets on the Consolidated Balance Sheets. We recorded unrealized gains of $18 million, $94 million and $729 million for the years ended December 31, 2023, 2022 and 2021, respectively. Unrealized losses were $142 million, $388 million and $2 million for the years ended December 31, 2023, 2022 and 2021, respectively. Unrealized gains and losses are recorded in Other, net on the Consolidated Statements of Income. Since the adoption of new accounting guidance on the recognition and measurement of financial assets and financial liabilities on January 1, 2018, cumulative unrealized gains for equity investments without readily determinable fair values totaled $1.1 billion and $1.2 billion as of December 31, 2023 and 2022, respectively, and cumulative unrealized losses were $431 million and $394 million as of December 31, 2023 and 2022, respectively. In addition, we also have certain equity investments measured at fair value using the net asset value practical expedient. Such investments were immaterial as of both December 31, 2023 and 2022.
Guarantees | Our recognition of these instruments is at fair value. In addition, we establish reserves when a loss is probable and the amount can be reasonably estimated.
Income Taxes | We record a deferred income tax (benefit) provision when there are differences between assets and liabilities measured for financial reporting and for income tax return purposes. These temporary differences result in taxable or deductible amounts in future years and are measured using the tax rates and laws that will be in effect when such differences are expected to reverse. A valuation allowance is established when management determines that it is more likely than not that all or some portion of the benefit of the deferred tax assets will not be realized. The valuation allowances for both periods presented above are associated with certain non-U.S. deferred tax assets, state NOLs, and FTC carryforwards. Interest and penalties relating to unrecognized tax benefits are reported in the income tax provision.
Income Tax Uncertainties | The amount of benefit recognized for financial reporting purposes is based on management’s best judgment of the largest amount of benefit that is more likely than not to be realized on ultimate settlement with the taxing authority given the facts, circumstances and information available at the reporting date. We adjust the level of unrecognized tax benefits when there is new information available to assess the likelihood of the outcome.
Regulatory Matters and Capital Adequacy | RESTRICTED NET ASSETS OF SUBSIDIARIES Certain of our subsidiaries are subject to restrictions on the transfer of net assets under debt agreements and regulatory requirements. These restrictions have not had any effect on our shareholder dividend policy and management does not anticipate any impact in the future. Procedures exist to transfer net assets between the Company and its subsidiaries, while ensuring compliance with the various contractual and regulatory constraints. As of December 31, 2023, the aggregate amount of net assets of subsidiaries that are restricted to be transferred was approximately $13.6 billion. BANK HOLDING COMPANY DIVIDEND RESTRICTIONS We are limited in our ability to pay dividends by the Federal Reserve, which could prohibit a dividend that would be considered an unsafe or unsound banking practice. It is the policy of the Federal Reserve that bank holding companies generally should pay dividends on preferred and common stock only out of net income available to common shareholders generated over the past year, and only if prospective earnings retention is consistent with the organization’s current and expected future capital needs, asset quality and overall financial condition. Moreover, bank holding companies are required by statute to be a source of strength to their insured depository institution subsidiaries and should not maintain dividend levels that undermine their ability to do so. On an annual basis, we are required to develop and maintain a capital plan, which includes planned dividends. We may be subject to limitations and restrictions on our dividends, if, among other things, (i) our regulatory capital ratios do not satisfy applicable minimum requirements and buffers or (ii) we are required to resubmit our capital plan. BANK DIVIDEND RESTRICTIONS In the year ended December 31, 2023, AENB paid dividends from retained earnings to its parent of $3.6 billion. AENB is limited in its ability to pay dividends by banking statutes, regulations and supervisory policy. In general, applicable federal and state banking laws prohibit, without first obtaining regulatory approval, insured depository institutions, such as AENB, from making dividend distributions if such distributions are not paid out of available retained earnings or would cause the institution to fail to meet capital adequacy standards. If AENB’s risk-based capital ratios do not satisfy minimum regulatory requirements and applicable buffers, it will face graduated constraints on dividends and other capital distributions. In determining the dividends to pay its parent, AENB must also consider the effects on applicable risk-based capital and leverage ratio requirements, as well as policy statements of the federal regulatory agencies. In addition, AENB’s banking regulators have authority to limit or prohibit the payment of a dividend by AENB under a number of circumstances, including if, in the banking regulator’s opinion, payment of a dividend would constitute an unsafe or unsound banking practice in light of the financial condition of the banking organization.
Segment Reporting | We consider a combination of factors when evaluating the composition of our reportable operating segments, including the results reviewed by the chief operating decision maker, economic characteristics, products and services offered, classes of customers, product distribution channels, geographic considerations (primarily United States versus outside the United States), and regulatory environment considerations. Total Revenues Net of Interest Expense We allocate discount revenue and certain other revenues among segments using a transfer pricing methodology. Within the USCS, CS and ICS segments, discount revenue generally reflects the issuer component of the overall discount revenue generated by each segment’s Card Members; within the GMNS segment, discount revenue generally reflects the network and acquirer component of the overall discount revenue being allocated. Net card fees, processed revenue and certain other revenues are directly attributable to the segment in which they are reported. Interest and fees on loans and certain investment income is directly attributable to the segment in which it is reported. Interest expense represents an allocated funding cost based on a combination of segment funding requirements and internal funding rates. Provisions for Credit Losses The provisions for credit losses are directly attributable to the segment in which they are reported. Expenses Card Member rewards and Card Member services expenses are included in each segment based on the actual expenses incurred. Business development and Marketing expenses are included in each segment based on the actual expenses incurred. Global brand advertising is primarily allocated to the segments based on the relative levels of revenue. Salaries and employee benefits and other expenses reflect both costs incurred directly within each segment, as well as allocated expenses. The allocated expenses include service costs, which primarily reflect salaries and benefits associated with our technology and customer servicing groups, and overhead expenses. Service costs are allocated based on activities directly attributable to the segment, and overhead expenses are allocated based on the relative levels of revenue and Card Member loans and receivables.
