Summary of Significant Accounting Policies |
NOTE 1—SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
The Company Capital One Financial Corporation, a Delaware corporation established in 1994 and headquartered in McLean, Virginia, is a diversified financial services holding company with banking and non-banking subsidiaries. Capital One Financial Corporation and its subsidiaries (the “Company” or “Capital One”) offer a broad array of financial products and services to consumers, small businesses and commercial clients through digital channels, branch locations, cafés and other distribution channels. As of September 30, 2024, Capital One Financial Corporation’s principal operating subsidiary was Capital One, National Association (“CONA”). The Company is hereafter collectively referred to as “we,” “us” or “our.” CONA is referred to as the “Bank.” We also offer products outside of the United States of America (“U.S.”) principally through Capital One (Europe) plc (“COEP”), an indirect subsidiary of CONA organized and located in the United Kingdom (“U.K.”), and through a branch of CONA in Canada. Both COEP and our Canadian branch of CONA have the authority to provide credit card loans. Our principal operations are organized for management reporting purposes into three major business segments, which are defined primarily based on the products and services provided or the types of customer served: Credit Card, Consumer Banking and Commercial Banking. We provide details on our business segments, the integration of any recent material acquisitions into our business segments, and the allocation methodologies and accounting policies used to derive our business segment results in “Note 13—Business Segments and Revenue from Contracts with Customers.” Basis of Presentation and Use of Estimates The accompanying unaudited interim consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the U.S. (“U.S. GAAP”). The preparation of the consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and in the related disclosures. These estimates are based on information available as of the date of the consolidated financial statements. While management makes its best judgments, actual amounts or results could differ from these estimates. In the opinion of management, all normal, recurring adjustments have been included for a fair statement of this interim financial information. These unaudited interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements, and related notes thereto, included in Capital One Financial Corporation’s 2023 Annual Report on Form 10-K (“2023 Form 10-K”).

Tax Credit Investments ASU No. 2023-02, Investments - Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method Issued March 2023 |  | Permits entities to elect to account for their tax equity investments, regardless of the tax credit program from which the income tax credits are received, using the proportional amortization method, if certain criteria are met. Previously, only Low-Income Housing Tax Credit investments were eligible for application of the proportional amortization method. |  | We adopted this standard on its effective date of January 1, 2024 using a modified retrospective transition method, which results in a cumulative-effect adjustment to retained earnings in the period of adoption. Our adoption of this standard did not have a material impact on our consolidated financial statements. See “Consolidated Statements of Changes in Stockholders’ Equity” and “Note 6—Variable Interest Entities and Securitizations” for additional disclosures.
