Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Basis of Presentation | The preparation of Consolidated Financial Statements in conformity with accounting principles generally accepted in the United States of America (GAAP) requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and the disclosures of contingent assets and liabilities. These accounting estimates reflect the best judgment of management, but actual results could differ.
Reclassifications | Certain reclassifications of prior period amounts have been made to conform to the current period presentation.
Recently Issued Accounting Standards | Recently Issued Accounting Standards In December 2023, the Financial Accounting Standards Board issued updated accounting guidance on Disclosures for Income Taxes, effective for annual reporting periods beginning after December 15, 2024, 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). The updated guidance is not expected to have a material impact to our Consolidated Financial Statements. In November 2024 and as amended in January 2025, the Financial Accounting Standards Board issued updated accounting guidance on the Disaggregation of Income Statement Expenses for annual reporting periods beginning after December 15, 2026 and for interim reporting periods beginning December 15, 2027, with early adoption permitted. The updated guidance includes the requirement for a new tabular disclosure within a Note to the Consolidated Financial Statements, to disaggregate defined expense categories from the expense report lines presented on the Consolidated Statements of Income. We are currently assessing the updated guidance and its impact to our Consolidated Financial Statements. In September 2025, the Financial Accounting Standards Board issued updated guidance on accounting for internal-use software, effective for annual reporting periods beginning after December 15, 2027, with early adoption permitted. The amendments modernize guidance to consider different methods of software development, updating the requirements for capitalization of software costs. We are currently assessing the updated guidance; however, it is not expected to have a material impact to our Consolidated Financial Statements.
Reserves for Credit Losses | 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 Current Expected Credit Loss (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. For Other loans, we use vintage-based historical performance to estimate expected credit losses over the life of the loan, net of recovery estimates. 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 Card Member loans and receivables and 120 days past due for Other loans. Balances in bankruptcy or owed by deceased individuals are generally written off upon notification.
Investment Securities | Investment securities principally include available-for-sale (AFS) debt securities carried at fair value on the Consolidated Balance Sheets. Unrealized losses attributable to credit deterioration are recorded in 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. Investment securities also include equity securities carried at fair value on the Consolidated Balance Sheets with unrealized gains and losses recorded in the Consolidated Statements of Income as Other, net expense. Realized gains and losses are recognized upon disposition of the securities using the specific identification method and recorded in the Consolidated Statements of Income as Other, net expense.
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. 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.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.
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 $300 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 | A majority of our derivative assets and liabilities as of September 30, 2025 and December 31, 2024 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. We primarily designate foreign currency derivatives (typically foreign exchange forwards) and, in certain cases, we also designate foreign currency-denominated debt, as hedging instruments to reduce our exposure to changes in currency exchange rates on net investments in foreign subsidiaries with non-U.S. dollar functional currency.The changes in the fair value of derivatives that are not designated as hedges are primarily intended to offset the related foreign exchange gains or losses of the underlying foreign currency exposures.
Fair Values | We have certain assets that are subject to measurement at fair value on a nonrecurring basis. Equity investments without readily determinable fair values, which include investments in our Amex Ventures portfolio, are measured at fair value in periods subsequent to their initial recognition if they are determined to be impaired or where there is an observable price change for an identical or similar investment of the same issuer. We generally estimate the fair value of these investments based on the observed transaction price. 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 these investments represents a Level 3 fair value measurement.
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.
