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, 2022, our principal subsidiaries included: •Capital One Bank (USA), National Association (“COBNA”), which offers credit card products along with other lending products and consumer services; and •Capital One, National Association (“CONA”), which offers a broad spectrum of banking products and financial services to consumers, small businesses and commercial clients. On October 1, 2022, the Company completed the merger of COBNA with and into CONA, with CONA as the surviving entity. The Company is hereafter collectively referred to as “we,” “us” or “our.” COBNA and CONA are collectively referred to as the “Banks.” We also offer products outside of the United States of America (“U.S.”) principally through Capital One (Europe) plc (“COEP”), an indirect subsidiary of COBNA organized and located in the United Kingdom (“U.K.”), and through a branch of COBNA in Canada. COEP has authority, among other things, to provide credit card loans. Our branch of COBNA in Canada also has 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 recent acquisitions, if any, into our business segments and the allocation methodologies and accounting policies used to derive our business segment results in “Note 12—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 2021 Annual Report on Form 10-K (“2021 Form 10-K”).

Fair Value Hedging ASU No. 2022-01, Derivatives and Hedging (Topic 815): Fair Value Hedging - Portfolio Layering Method Issued March 2022 |  | The amendments in this ASU establish the portfolio-layer method which provides flexibility to achieve fair value hedge accounting for multiple hedged layers within a single closed portfolio of financial assets. |  | We adopted this guidance in the second quarter of 2022 using the prospective method of adoption. Our adoption of this standard did not have an impact on our consolidated financial statements as any designation of portfolio layer method hedges would be applied prospectively.
