Accounting Policies [Abstract] |
Summary of Significant Accounting Policies | Note 1—Summary of Significant Accounting Policies Organization. Visa Inc., together with its subsidiaries (Visa or the Company), is a global payments technology company that facilitates secure, reliable and efficient global commerce and money movement. Visa provides transaction processing services (primarily authorization, clearing and settlement) among consumers, issuing and acquiring financial institutions and sellers through its electronic payments network, VisaNet. Visa is focused on extending, enhancing and investing in its proprietary advanced transaction processing network, VisaNet, to offer a single connection point for facilitating money movement to multiple endpoints through various form factors and innovative technologies across more than 200 countries and territories. Visa is not a financial institution and does not issue cards, extend credit or set rates and fees for account holders of Visa products. In most cases, account holder and seller relationships belong to, and are managed by, Visa’s financial institution clients. Consolidation and basis of presentation. The accompanying unaudited consolidated financial statements include the accounts of Visa and its consolidated entities and are presented in accordance with accounting principles generally accepted in the United States of America (GAAP). The Company consolidates entities for which it has a controlling financial interest, as well as variable interest entities (VIEs) for which the Company is the primary beneficiary. The Company’s investments in VIEs have not been material to its unaudited consolidated financial statements as of and for the periods presented. Intercompany balances and transactions have been eliminated in consolidation. The accompanying unaudited consolidated financial statements are presented in accordance with the U.S. Securities and Exchange Commission (SEC) requirements for Quarterly Reports on Form 10-Q and, consequently, do not include all of the annual disclosures required by GAAP. Reference should be made to Visa’s Annual Report on Form 10-K for the year ended September 30, 2025 for additional disclosures, including a summary of the Company’s significant accounting policies. In the opinion of management, the accompanying unaudited consolidated financial statements include all normal recurring adjustments necessary for a fair presentation of the Company’s financial position, results of operations and cash flows for the interim periods presented. The results of operations for interim periods are not necessarily indicative of results for the full year. Use of estimates. The preparation of the accompanying unaudited consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions about future events. These estimates and assumptions affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the unaudited consolidated financial statements and reported amounts of revenue and expenses during the reporting period. These estimates may change as new events occur and additional information is obtained, and such changes will be recognized in the period in which they occur. Future actual results could differ materially from these estimates. Recently adopted accounting pronouncement. In November 2025, the Financial Accounting Standards Board issued Accounting Standards Update 2025-09, which includes amendments to more closely align hedge accounting with the economics of an entity’s risk management activities. During the three months ended December 31, 2025, the Company early adopted this standard on a prospective basis. The adoption did not have a material impact on the unaudited consolidated financial statements.
