Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The Company We are a globally integrated payments company, providing customers with access to products, insights and experiences that enrich lives and build business success. Our principal products and services are credit and charge card products, along with travel and lifestyle related services, offered to consumers and businesses around the world. Our various products and services are offered globally to diverse customer groups, including consumers, small businesses, mid-sized companies and large corporations. These products and services are offered through various channels, including mobile and online applications, affiliate marketing, customer referral programs, third-party service providers and business partners, direct mail, telephone, in-house sales teams and direct response advertising. The accompanying Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 2022 (the 2022 Form 10-K). If not materially different, certain note disclosures included therein have been omitted from these Consolidated Financial Statements. The interim Consolidated Financial Statements included in this report have not been audited. In the opinion of management, all adjustments, which consist of normal recurring adjustments necessary for a fair statement of the interim Consolidated Financial Statements, have been made. Results of operations reported for interim periods are not necessarily indicative of results for the entire year. 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. Recently Adopted and Issued Accounting Standards Effective January 1, 2023, we adopted new accounting guidance on troubled debt restructurings (TDR) and vintage disclosures (Update 2022-02) on a prospective basis. The new guidance eliminated the existing TDR guidance for those entities that have adopted Update 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 on our Consolidated Financial Statements, and we do not expect it to have a material impact to our Consolidated Financial Statements prospectively. 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 plan to early adopt the updated guidance with respect to other qualifying investments in the fourth quarter of 2023. We do not expect the updated guidance to have a material impact to our Consolidated Financial Statements.

A Card Member account is considered 90 days past billing if payment has not been received within 90 days of the Card Member’s billing statement date. In addition, if we initiate collection procedures on an account prior to the account becoming 90 days past billing, the associated Card Member loan or receivable balance is classified as 90 days past billing. These amounts are shown above as 90+ Days Past Due for presentation purposes. See also (b). (b) Delinquency data for periods other than 90+ days past billing is not available due to system constraints. Therefore, such data has not been utilized for risk management purposes. The balances that are current to 89 days past due can be derived as the difference between the Total and the 90+ Days Past Due balances. (c) Our policy is generally to accrue interest through the date of write-off (typically 180 days past due). We establish reserves for interest that we believe will not be collected. (d) Non-accrual loans primarily include certain loans placed with outside collection agencies for which we have ceased accruing interest. Credit Quality Indicators for Card Member Loans and Receivables The following tables present the key credit quality indicators as of or for the nine months ended September 30: 2023 2022 Net Write-Off Rate Net Write-Off Rate Principal Only (a) Principal, Interest & Fees (a) 30+ Days Past Due as a % of Total Principal Only (a) Principal, Interest & Fees (a) 30+ Days Past Due as a % of Total Card Member Loans: Consumer 1.7 % 2.1 % 1.3 % 0.9 % 1.1 % 0.9 % Small Business 1.5 % 1.8 % 1.3 % 0.6 % 0.7 % 0.7 % Card Member Receivables: Consumer 1.6 % 1.7 % 1.0 % 0.7 % 0.8 % 1.0 % Small Business 2.3 % 2.4 % 1.3 % 0.9 % 1.0 % 1.3 % Corporate (b) 0.6 % (c) (b) 0.3 % (c) (a) We present a net write-off rate based on principal losses only (i.e., excluding interest and/or fees) to be consistent with industry convention. In addition, as our practice is to include uncollectible interest and/or fees as part of our total provision for credit losses, a net write-off rate including principal, interest and/or fees is also presented. (b) Net write-off rate based on principal losses only is not available due to system constraints. (c) For corporate receivables, delinquency data is tracked based on days past billing status rather than days past due. Delinquency data for periods other than 90+ days past billing is not available due to system constraints. 90+ days past billing as a % of total was 0.5% and 0.6% as of September 30, 2023 and 2022, respectively. Refer to Note 3 for additional indicators, including external qualitative factors, management considers in its evaluation process for reserves for credit losses. Loans and Receivables Restructurings for Borrowers Experiencing Financial Difficulty Effective January 1, 2023, we prospectively adopted Accounting Standards Update 2022-02 guidance that eliminated the recognition and measurement of TDRs. Following the adoption of this guidance, we evaluate all loans and receivables restructurings according to the accounting guidance for loan refinancing and restructuring to determine whether such loan modification should be accounted for as a new loan or a continuation of the existing loan. Our loans and receivables restructurings for borrowers experiencing financial difficulty are generally accounted for as a continuation of the existing loan, which reflects the ongoing effort to support our customer and recover our investment in the existing loan. We offer several types of loans and receivables modification programs to customers experiencing financial difficulty. In such instances, we may modify loans and receivables with the intention to minimize losses and improve collectability, while providing customers with temporary or permanent financial relief. Such modifications to the loans and receivables primarily include (i) temporary interest rate reductions (reducing interest rates to as low as zero percent, in which case the loan is characterized as non-accrual), and/or (ii) placing the customer on a fixed payment plan not to exceed 60 months. Upon entering the modification program, the customer’s ability to make future purchases is limited, canceled or, in certain cases, suspended until the customer successfully exits from the modification program. As of September 30, 2023, we had $48 million of unused credit available to customers with loans modified during the nine months ended September 30, 2023. In accordance with the modification agreement with the customer, loans and/or receivables may revert to the original contractual terms (including the contractual interest rate where applicable) when the customer exits the modification program, which is either (i) when all payments have been made in accordance with the modification agreement or (ii) when the customer defaults out of the modification program. The following table provides information relating to loans and receivables modifications for borrowers experiencing financial difficulty during the three and nine months ended September 30, 2023: Three Months Ended September 30, 2023 Nine Months Ended September 30, 2023 Account Balances ( Millions ) (a) % of Total Class of Financing Receivables Weighted Average Interest Rate Reduction Weighted Average Payment Account Balances ( Millions ) (a) % of Total Class of Financing Receivables Weighted Average Interest Rate Reduction Weighted Average Payment Interest Rate Reduction Card Member Loans Consumer $ 542 0.6 % 16.4 % (b) $ 1,113 1.2 % 16.1 % (b) Small Business 167 0.6 % 15.9 % (b) 411 1.5 % 15.7 % (b) Corporate — — — (b) — — — (b) Term Extension Card Member Receivables Consumer 126 0.6 % (c) 30 282 1.3 % (c) 27 Small Business 181 0.9 % (c) 30 455 2.3 % (c) 27 Corporate 4 0.02 % (c) 10 12 0.1 % (c) 10 Other Loans 8 0.1 % — 19 19 0.3 % — 18 Interest Rate Reduction Other Loans 16 0.2 % 2.1 % 20 28 0.4 % 2.0 % 19 Total $ 1,044 $ 2,320 (a) Represents the outstanding balances as of September 30, 2023 of all modifications undertaken in the past three and nine months, respectively, for loans and receivables that remain in modification programs as of, or that defaulted on or before, September 30, 2023.

Troubled Debt Restructuring Disclosures Prior to Our Adoption of ASU 2022-02 Prior to our adoption of ASU 2022-02, we accounted for a modification to the contractual terms of a loan that resulted in granting a concession to a borrower experiencing financial difficulties as a TDR. Loans that were classified as a TDR prior to the adoption of ASU 2022-02 will continue to be accounted for under the historical TDR accounting until the loan is entirely paid off or written off.

Reserves for Credit Losses

Reserves for Credit Losses	9 Months Ended

Receivables [Abstract]
Reserve for Credit Losses	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 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. 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. The following table reflects the range of macroeconomic scenario key variables used, in conjunction with other inputs, to calculate reserves for credit losses: U.S. Unemployment Rate U.S. GDP Growth (Contraction) (a) September 30, 2023 December 31, 2022 September 30, 2023 December 31, 2022 Third quarter of 2023 4% 3% - 7% 2% 5% - (2)% Fourth quarter of 2023 3% - 6% 3% - 8% 4% - (3)% 6% - 0.2% Fourth quarter of 2024 3% - 8% 3% - 7% 2% - 1% 3% - 2% Fourth quarter of 2025 4% - 7% 3% - 6% 4% - 2% 4% - 3% (a) Real GDP quarter over quarter percentage change seasonally adjusted to annualized rates. Changes in Card Member Loans Reserve for Credit Losses Card Member loans reserve for credit losses increased for both the three and nine months ended September 30, 2023, primarily driven by increases in loans outstanding and higher delinquencies. Card Member loans reserve for credit losses increased for the three months ended September 30, 2022, primarily driven by an increase in loans outstanding and deterioration in the macroeconomic outlook at that time. Card Member loans reserve for credit losses increased for the nine months ended September 30, 2022, primarily driven by an increase in loans outstanding and deterioration in the macroeconomic outlook at that time, partially offset by a reduction in COVID-19 pandemic-driven reserves.

Investments, Debt and Equity Securities [Abstract]
Investment Securities	Investment Securities Investment securities principally include available-for-sale 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. We had accrued interest on our available-for-sale debt securities totaling $12 million as of both September 30, 2023 and December 31, 2022, presented as Other assets on the Consolidated Balance Sheets. 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. The following is a summary of investment securities as of September 30, 2023 and December 31, 2022: 2023 2022 Description of Securities (Millions) Cost Gross Gross Estimated Cost Gross Gross Estimated Available-for-sale debt securities: State and municipal obligations $ 62 $ — $ (10) $ 52 $ 64 $ — $ (10) $ 54 U.S. Government agency obligations 4 — — 4 5 — — 5 U.S. Government treasury obligations (a) 2,214 — (27) 2,187 3,859 — (73) 3,786 Mortgage-backed securities (b) 12 — (1) 11 13 — — 13 Foreign government bonds and obligations 777 — (1) 776 633 — (1) 632 Other (c) 64 — — 64 47 — — 47 Equity securities (d)(e) 60 20 (14) 66 50 — (9) 41 Total $ 3,193 $ 20 $ (53) $ 3,160 $ 4,671 $ — $ (93) $ 4,578 (a) Excludes approximately $1 billion of U.S. Government treasury obligations that matured on September 30, 2023, for which cash was received on October 2, 2023. As of September 30, 2023, these investments were derecognized and a corresponding receivable was recorded in Other assets on the Consolidated Balance Sheets; this non-cash movement is not reflected in the Consolidated Statements of Cash Flows. (b) Represents mortgage-backed securities guaranteed by Fannie Mae, Freddie Mac or Ginnie Mae. (c) Represents investments in debt securities issued by Community Development Financial Institutions. (d) Equity securities comprise investments in common stock, exchange-traded funds and mutual funds. (e) During the third quarter of 2023, certain equity securities were reclassified from Other assets to Investment securities following the completion of transactions pursuant to which the issuers of the securities became public companies. The investments had a fair value of $26 million with an associated cost basis of $10 million as of September 30, 2023. The gross unrealized gain and loss amounts include net unrealized gains of $37 million that were recognized prior to such transactions. The following table provides information about our available-for-sale debt securities with gross unrealized losses and the length of time that individual securities have been in a continuous unrealized loss position as of September 30, 2023 and December 31, 2022: 2023 2022 Less than 12 months 12 months or more Less than 12 months 12 months or more Description of Securities ( Millions ) Estimated Fair Value Gross Estimated Fair Value Gross Estimated Fair Value Gross Estimated Fair Value Gross State and municipal obligations $ 20 $ (1) $ 30 $ (9) $ 52 $ (10) $ — $ — U.S. Government treasury obligations — — 2,098 (27) 3,710 (72) 52 (1) Mortgage-backed securities — — 7 (1) — — — — Foreign government bonds and obligations 679 (1) — — 549 (1) — — Total $ 699 $ (2) $ 2,135 $ (37) $ 4,311 $ (83) $ 52 $ (1) The gross unrealized losses on our available-for-sale debt securities are primarily attributable to an increase in the current benchmark interest rate. Overall, for the available-for-sale debt securities in gross unrealized loss positions, (i) we do not intend to sell the securities, (ii) it is more likely than not that we will not be required to sell the securities before recovery of the unrealized losses, and (iii) we expect that the contractual principal and interest will be received on the securities. We concluded that there was no credit loss attributable to the securities in an unrealized loss position for the periods presented. The following table summarizes the gross unrealized losses for available-for-sale debt securities by ratio of fair value to amortized cost as of September 30, 2023 and December 31, 2022: Less than 12 months 12 months or more Total Ratio of Fair Value to Amortized Cost ( Dollars in millions ) Number of Estimated Gross Number of Estimated Gross Number of Estimated Gross 2023: 90–100% 53 $ 699 $ (2) 44 $ 2,107 $ (27) 97 $ 2,806 $ (29) Less than 90% — $ — $ — 32 $ 28 $ (10) 32 $ 28 $ (10) Total as of September 30, 2023 53 $ 699 $ (2) 76 $ 2,135 $ (37) 129 $ 2,834 $ (39) 2022: 90–100% 74 $ 4,287 $ (74) 3 $ 52 $ (1) 77 $ 4,339 $ (75) Less than 90% 14 $ 24 $ (9) — $ — $ — 14 $ 24 $ (9) Total as of December 31, 2022 88 $ 4,311 $ (83) 3 $ 52 $ (1) 91 $ 4,363 $ (84) Contractual maturities for available-for-sale debt securities with stated maturities as of September 30, 2023 were as follows: (Millions) Cost Estimated Due within 1 year $ 2,804 $ 2,784 Due after 1 year but within 5 years 233 226 Due after 5 years but within 10 years 40 39 Due after 10 years 56 45 Total $ 3,133 $ 3,094 The expected payments on state and municipal obligations, U.S. Government agency obligations and mortgage-backed securities may not coincide with their contractual maturities because the issuers have the right to call or prepay certain obligations.

Asset Securitizations

Asset Securitizations	9 Months Ended

Asset Securitizations [Abstract]
Asset Securitizations	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. Our ownership of variable interests for the Lending Trust was $14.0 billion and $16.0 billion as of September 30, 2023 and December 31, 2022, respectively, and for the Charge Trust was $5.4 billion and $5.2 billion as of September 30, 2023 and December 31, 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. Restricted cash and cash equivalents held by the Lending Trust was $60 million and $59 million as of September 30, 2023 and December 31, 2022, respectively, and for the Charge Trust was nil as of both September 30, 2023 and December 31, 2022. These amounts relate to collections of Card Member loans and receivables to be used by the Trusts to fund future expenses and obligations, including interest on debt securities, credit losses and upcoming debt maturities. Under the respective terms of the Lending Trust and the Charge Trust agreements, the occurrence of certain triggering events associated with the performance of the assets of each Trust could result in payment of trust expenses, establishment of reserve funds, or, in a worst-case scenario, early amortization of debt securities. During the nine months ended September 30, 2023 and the year ended December 31, 2022, no such triggering events occurred.

Commitments and Contingencies Disclosure [Abstract]
Contingencies	Contingencies In the ordinary course of business, we and our subsidiaries are subject to various pending and potential legal actions, arbitration proceedings, claims, investigations, examinations, regulatory proceedings, information gathering requests, subpoenas, inquiries and matters relating to compliance with laws and regulations (collectively, legal proceedings). Based on our current knowledge, and taking into consideration our litigation-related liabilities, we do not believe we are a party to, nor are any of our properties the subject of, any legal proceeding that would have a material adverse effect on our consolidated financial condition or liquidity. However, in light of the uncertainties involved in such matters, including the fact that some pending legal proceedings are at preliminary stages or seek an indeterminate amount of damages, it is possible that the outcome of legal proceedings could have a material impact on our results of operations. Certain legal proceedings involving us or our subsidiaries are described below. On February 25, 2020, we were named as a defendant in a case filed in the Superior Court of California, Los Angeles County, captioned Laurelwood Cleaners LLC v. American Express Co., et al. , in which the plaintiff seeks a public injunction in California prohibiting American Express from enforcing its anti-steering and non-discrimination provisions and from requiring merchants “to offer the service of Amex-card acceptance for free.” The case has been stayed pending the outcome of arbitration proceedings. On January 29, 2019, we were named in a putative class action brought in the United States District Court for the Eastern District of New York, captioned Anthony Oliver, et al. v. American Express Company and American Express Travel Related Services Company Inc. , in which the plaintiffs are holders of MasterCard, Visa and/or Discover credit cards (but not American Express cards) and allege they paid higher prices as a result of our anti-steering and non-discrimination provisions in violation of federal antitrust law and the antitrust and consumer laws of various states. Plaintiffs seek unspecified damages and other forms of relief. The court dismissed plaintiffs’ federal antitrust claim, numerous state antitrust and consumer protection claims and their unjust enrichment claim. The remaining claims in plaintiffs’ complaint arise under the antitrust laws of 11 states and the consumer protection laws of six states. On March 8, 2016, plaintiffs B&R Supermarket, Inc. d/b/a Milam’s Market and Grove Liquors LLC, on behalf of themselves and others, filed a suit, captioned B&R Supermarket, Inc. d/b/a Milam’s Market, et al. v. Visa Inc., et al. , for violations of the Sherman Antitrust Act, the Clayton Antitrust Act, California’s Cartwright Act and unjust enrichment in the United States District Court for the Northern District of California, against American Express Company, other credit and charge card networks, other issuing banks and EMVCo, LLC. Plaintiffs allege that the defendants, through EMVCo, conspired to shift liability for fraudulent, faulty and otherwise rejected consumer credit card transactions from themselves to merchants after the implementation of EMV chip payment terminals. Plaintiffs seek damages and injunctive relief. An amended complaint was filed on July 15, 2016. On September 30, 2016, the court denied our motion to dismiss as to claims brought by merchants who do not accept American Express cards, and on May 4, 2017, the California court transferred the case to the United States District Court for the Eastern District of New York. On August 28, 2020, the court granted plaintiffs’ motion for class certification. In July 2004, we were named as a defendant in a putative class action filed in the Southern District of New York and subsequently transferred to the Eastern District of New York, captioned The Marcus Corporation v. American Express Co., et al. , in which the plaintiffs allege an unlawful antitrust tying arrangement between certain of our charge cards and credit cards in violation of various state and federal laws. The plaintiffs in this action seek injunctive relief and an unspecified amount of damages. In 2006, Mawarid Investments Limited filed a request for confidential arbitration under the 1998 London Court of International Arbitration Rules in connection with certain claims arising under a shareholders agreement between Mawarid and American Express Travel Related Services Company, Inc. relating to a joint venture between the parties, Amex (Middle East) BSC(c) (AEME). In 2008, the tribunal rendered a partial award, including a direction that an audit should take place to verify whether acquirer discount revenue related to transactions occurring with airlines located in the Middle East region had been properly allocated to AEME since its inception in 1992. In September 2021, the tribunal rendered a further partial award regarding the location of transactions through non-physical channels. In May 2022, the tribunal further clarified the 2021 partial award and the discount rate that should apply to transactions through non-physical channels. In May 2020, we began responding to a review by the Office of the Comptroller of the Currency (OCC) and the Department of Justice (DOJ) Civil Division regarding historical sales practices relating to sales to small business customers in the United States. In January 2021, we received a grand jury subpoena from the United States Attorney’s Office for the Eastern District of New York (EDNY) regarding these sales practices issues, as well as a Civil Investigative Demand from the Consumer Financial Protection Bureau (CFPB) pertaining to its investigation into sales practices related to consumers. We have also been made aware of a related investigation by the New York Department of Financial Services (NYDFS). In January 2023, the CFPB notified us that its investigation was completed and that it does not intend to recommend an enforcement action be taken against us at this time. In July 2023, we reached a settlement with the OCC to resolve its review of historical sales practices to certain U.S. small business card customers that occurred between 2015 and 2017, and paid a civil money penalty of $15 million. The DOJ, EDNY and NYDFS investigations are ongoing, and we are cooperating with all inquiries. Any additional negotiated resolution or litigated proceedings arising from these matters could result in fines or other remedial actions. We are being challenged in a number of countries regarding our application of value-added taxes (VAT) to certain of our international transactions, which are in various stages of audit, or are being contested in legal actions. While we believe we have complied with all applicable tax laws, rules and regulations in the relevant jurisdictions, the tax authorities may determine that we owe additional VAT. In certain jurisdictions where we are contesting the assessments, we were required to pay the VAT assessments prior to contesting. Our legal proceedings range from cases brought by a single plaintiff to class actions with millions of putative class members to governmental proceedings. These legal proceedings involve various lines of business and a variety of claims (including, but not limited to, common law tort, contract, application of tax laws, antitrust and consumer protection claims), some of which present novel factual allegations and/or unique legal theories. While some matters pending against us specify the damages sought, many seek an unspecified amount of damages or are at very early stages of the legal process. Even when the amount of damages claimed against us are stated, the claimed amount may be exaggerated and/or unsupported. As a result, some matters have not yet progressed sufficiently through discovery and/or development of important factual information and legal issues to enable us to estimate an amount of loss or a range of possible loss, while other matters have progressed sufficiently such that we are able to estimate an amount of loss or a range of possible loss. 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 $310 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.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives and Hedging Activities	Derivatives and Hedging Activities We use derivative financial instruments to manage exposures to various market risks. These instruments derive their value from an underlying variable or multiple variables, including interest rates and foreign exchange rates, and are carried at fair value on the Consolidated Balance Sheets. These instruments enable end users to increase, reduce or alter exposure to various market risks and, for that reason, are an integral component of our market risk management. We do not transact in derivatives for trading purposes. A majority of our derivative assets and liabilities as of September 30, 2023 and December 31, 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. In relation to our credit risk, certain of our bilateral derivative agreements include provisions that allow our counterparties to terminate the relevant agreement in the event of a downgrade of our debt credit rating below investment grade and settle the outstanding net liability position. As of September 30, 2023, these derivatives were not in a material net liability position. Based on our assessment of the credit risk of our derivative counterparties and our own credit risk as of September 30, 2023 and December 31, 2022, no credit risk adjustment to the derivative portfolio was required. The following table summarizes the total fair value, excluding interest accruals, of derivative assets and liabilities as of September 30, 2023 and December 31, 2022: Other Assets Fair Value Other Liabilities Fair Value (Millions) 2023 2022 2023 2022 Derivatives designated as hedging instruments: Fair value hedges - Interest rate contracts (a) $ — $ — $ 157 $ 211 Net investment hedges - Foreign exchange contracts 176 350 81 251 Total derivatives designated as hedging instruments 176 350 238 462 Derivatives not designated as hedging instruments: Foreign exchange contracts and other 418 171 63 339 Total derivatives, gross 594 521 301 801 Derivative asset and derivative liability netting (b) (91) (257) (91) (257) Cash collateral netting (c) (7) (11) (157) (212) Total derivatives, net $ 496 $ 253 $ 53 $ 332 (a) For our centrally cleared derivatives, variation margin payments are legally characterized as settlement payments as opposed to collateral. (b) Represents the amount of netting of derivative assets and derivative liabilities executed with the same counterparty under an enforceable master netting arrangement. (c) Represents the offsetting of the fair value of bilateral interest rate contracts and certain foreign exchange contracts with the right to cash collateral held from the counterparty or cash collateral posted with the counterparty. We posted $137 million and $8 million as of September 30, 2023 and December 31, 2022, respectively, as initial margin on our centrally cleared interest rate swaps; such amounts are recorded within Other assets on the Consolidated Balance Sheets and are not netted against the derivative balances. Fair Value Hedges We are exposed to interest rate risk associated with our fixed-rate debt obligations. At the time of issuance, certain fixed-rate long-term debt obligations are designated in fair value hedging relationships, using interest rate swaps, to economically convert the fixed interest rate to a floating interest rate. We had $9.5 billion and $8.1 billion of fixed-rate debt obligations designated in fair value hedging relationships as of September 30, 2023 and December 31, 2022, respectively. The following table presents the gains and losses recognized in Interest expense on the Consolidated Statements of Income associated with the fair value hedges of our fixed-rate long-term debt for the three and nine months ended September 30: Gains (losses) Three Months Ended Nine Months Ended (Millions) 2023 2022 2023 2022 Fixed-rate long-term debt $ 52 $ 121 $ 14 $ 485 Derivatives designated as hedging instruments (52) (121) (15) (488) Total $ — $ — $ (1) $ (3) The carrying values of the hedged liabilities, recorded within Long-term debt on the Consolidated Balance Sheets, were $9.2 billion and $7.8 billion as of September 30, 2023 and December 31, 2022, respectively, including the cumulative amount of fair value hedging adjustments of $(250) million and $(236) million for the respective periods. We recognized in Interest expense on Long-term debt net increases of $47 million and $3 million for the three months ended September 30, 2023 and 2022, respectively, and a net increase of $130 million and a net decrease of $88 million for the nine months ended September 30, 2023 and 2022, respectively, primarily related to the net settlements including interest accruals on our interest rate derivatives designated as fair value hedges. Net Investment Hedges 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 had notional amounts of approximately $13.1 billion and $12.5 billion of foreign currency derivatives designated as net investment hedges as of September 30, 2023 and December 31, 2022, respectively. The gain or loss on net investment hedges, net of taxes, recorded in Accumulated other comprehensive income (loss) (AOCI) as part of the cumulative translation adjustment, were gains of $244 million and $520 million for the three months ended September 30, 2023 and 2022, respectively, and a loss of $261 million and a gain of $728 million for the nine months ended September 30, 2023 and 2022, respectively. Net investment hedge reclassifications out of AOCI into the Consolidated Statements of Income were not significant for any of the three and nine months ended September 30, 2023 and 2022. Derivatives Not Designated as Hedges 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. We had notional amounts of approximately $22.3 billion and $21.7 billion as of September 30, 2023 and December 31, 2022, respectively. The changes in the fair value of the derivatives and the related underlying foreign currency exposures resulted in net gains of $26 million and $23 million for the three months ended September 30, 2023 and 2022, respectively, and net gains of $56 million and $10 million for the nine months ended September 30, 2023 and 2022, respectively, that are recognized in Other, net expenses in the Consolidated Statements of Income.

Management reviews and applies judgment to the valuation of the embedded derivative that is performed by an independent third party using a Monte Carlo simulation that models a range of probable future stock prices based on implied volatility in a risk neutral framework. Refer to Note 8 for additional information about this embedded derivative. Financial Assets and Financial Liabilities Carried at Other Than Fair Value The following table summarizes the estimated fair values of our financial assets and financial liabilities that are measured at amortized cost, and not required to be carried at fair value on a recurring basis, as of September 30, 2023 and December 31, 2022. The fair values of these financial instruments are estimates based upon the market conditions and perceived risks as of September 30, 2023 and December 31, 2022, and require management’s judgment. These figures may not be indicative of future fair values, nor can the fair value of American Express be estimated by aggregating the amounts presented.

(c) Balances include amounts held by a consolidated VIE for which the fair values of Card Member loans were $27.2 billion and $28.4 billion as of September 30, 2023 and December 31, 2022, respectively, and the fair values of Long-term debt were $13.0 billion and $12.3 billion as of September 30, 2023 and December 31, 2022, respectively. (d) Presented as a component of Customer deposits on the Consolidated Balance Sheets. Nonrecurring Fair Value Measurements 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 September 30, 2023 and December 31, 2022, respectively, of which approximately $8 million and $597 million as of September 30, 2023 and December 31, 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 nil and $6 million for the three months ended September 30, 2023 and 2022, respectively, and nil and $94 million for the nine months ended September 30, 2023 and 2022, respectively. Unrealized losses representing impairments were $17 million and $51 million for the three months ended September 30, 2023 and 2022, respectively, and $122 million and $153 million for the nine months ended September 30, 2023 and 2022, 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 $1.0 billion and $1.2 billion as of September 30, 2023 and December 31, 2022, respectively, and cumulative unrealized losses representing impairments were $412 million and $394 million as of September 30, 2023 and December 31, 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 September 30, 2023 and December 31, 2022.

To date, we have not experienced any significant losses related to guarantees or indemnifications. 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 Tax Disclosure [Abstract]
Income Taxes	Income Taxes The effective tax rate was 20.9 percent and 23.6 percent for the three months ended September 30, 2023 and 2022, respectively, and 19.5 percent and 23.0 percent for the nine months ended September 30, 2023 and 2022, respectively. The lower effective tax rate for the three and nine month periods primarily reflected discrete tax benefits in the current periods and changes in the geographic mix of income. We are under continuous examination by the Internal Revenue Service (IRS) and tax authorities in other countries and states in which we have significant business operations. The tax years under examination and open for examination vary by jurisdiction. We are currently under examination by the IRS for the 2017 and 2018 tax years. We believe it is reasonably possible that our unrecognized tax benefits could decrease within the next twelve months by as much as $114 million, principally as a result of potential resolutions of prior years’ tax items with various taxing authorities. The prior years’ tax items include unrecognized tax benefits relating to the deductibility of certain expenses or losses and the attribution of taxable income to a particular jurisdiction or jurisdictions. Of the $114 million of unrecognized tax benefits, approximately $90 million relates to amounts that, if recognized, would impact the effective tax rate in a future period.

Earnings Per Common Share (EPS)	Earnings Per Common Share (EPS) The computations of basic and diluted EPS for the three and nine months ended September 30 were as follows: Three Months Ended Nine Months Ended (Millions, except per share amounts) 2023 2022 2023 2022 Numerator: Basic and diluted: Net income $ 2,451 $ 1,879 $ 6,441 $ 5,942 Preferred dividends (14) (14) (43) (43) Net income available to common shareholders $ 2,437 $ 1,865 $ 6,398 $ 5,899 Earnings allocated to participating share awards (a) (19) (14) (50) (45) Net income attributable to common shareholders $ 2,418 $ 1,851 $ 6,348 $ 5,854 Denominator: (a) Basic: Weighted-average common stock 732 748 738 752 Add: Weighted-average stock options (b) 1 1 1 1 Diluted 733 749 739 753 Basic EPS $ 3.30 $ 2.47 $ 8.60 $ 7.78 Diluted EPS $ 3.30 $ 2.47 $ 8.59 $ 7.77 (a) Our unvested restricted stock awards, which include the right to receive non-forfeitable dividends or dividend equivalents, are considered participating securities. Calculations of EPS under the two-class method exclude from the numerator any dividends paid or owed on participating securities and any undistributed earnings considered to be attributable to participating securities. The related participating securities are similarly excluded from the denominator. (b) The dilutive effect of unexercised stock options excludes from the computation of EPS 1.4 million and 0.3 million of options for the three months ended September 30, 2023 and 2022, respectively, and 1.4 million and 0.2 million of options for the nine months ended September 30, 2023 and 2022, respectively, because inclusion of the options would have been anti-dilutive.

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.
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 (Update 2022-02) on a prospective basis. The new guidance eliminated the existing TDR guidance for those entities that have adopted Update 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 on our Consolidated Financial Statements, and we do not expect it to have a material impact to our Consolidated Financial Statements prospectively. 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 plan to early adopt the updated guidance with respect to other qualifying investments in the fourth quarter of 2023. We do not expect the updated guidance 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 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.
Investment Securities	Investment securities principally include available-for-sale 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 $310 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, 2023 and December 31, 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.
Fair Values	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 September 30, 2023 and December 31, 2022, respectively, of which approximately $8 million and $597 million as of September 30, 2023 and December 31, 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 nil and $6 million for the three months ended September 30, 2023 and 2022, respectively, and nil and $94 million for the nine months ended September 30, 2023 and 2022, respectively. Unrealized losses representing impairments were $17 million and $51 million for the three months ended September 30, 2023 and 2022, respectively, and $122 million and $153 million for the nine months ended September 30, 2023 and 2022, 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 $1.0 billion and $1.2 billion as of September 30, 2023 and December 31, 2022, respectively, and cumulative unrealized losses representing impairments were $412 million and $394 million as of September 30, 2023 and December 31, 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 September 30, 2023 and December 31, 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.

A Card Member account is considered 90 days past billing if payment has not been received within 90 days of the Card Member’s billing statement date. In addition, if we initiate collection procedures on an account prior to the account becoming 90 days past billing, the associated Card Member loan or receivable balance is classified as 90 days past billing. These amounts are shown above as 90+ Days Past Due for presentation purposes. See also (b). (b) Delinquency data for periods other than 90+ days past billing is not available due to system constraints. Therefore, such data has not been utilized for risk management purposes. The balances that are current to 89 days past due can be derived as the difference between the Total and the 90+ Days Past Due balances. (c) Our policy is generally to accrue interest through the date of write-off (typically 180 days past due). We establish reserves for interest that we believe will not be collected. (d) Non-accrual loans primarily include certain loans placed with outside collection agencies for which we have ceased accruing interest.

In addition, as our practice is to include uncollectible interest and/or fees as part of our total provision for credit losses, a net write-off rate including principal, interest and/or fees is also presented. (b) Net write-off rate based on principal losses only is not available due to system constraints. (c) For corporate receivables, delinquency data is tracked based on days past billing status rather than days past due. Delinquency data for periods other than 90+ days past billing is not available due to system constraints. 90+ days past billing as a % of total was 0.5% and 0.6% as of September 30, 2023 and 2022, respectively.

Calculations of EPS under the two-class method exclude from the numerator any dividends paid or owed on participating securities and any undistributed earnings considered to be attributable to participating securities. The related participating securities are similarly excluded from the denominator. (b) The dilutive effect of unexercised stock options excludes from the computation of EPS 1.4 million and 0.3 million of options for the three months ended September 30, 2023 and 2022, respectively, and 1.4 million and 0.2 million of options for the nine months ended September 30, 2023 and 2022, respectively, because inclusion of the options would have been anti-dilutive.
