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.
