Summary of Significant Accounting Policies	Mar. 31, 2023
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 global commerce and money movement across more than 200 countries and territories. Visa operates one of the world’s largest electronic payments networks — VisaNet — which provides transaction processing services (primarily authorization, clearing and settlement). The Company offers products, solutions and services that facilitate secure, reliable and efficient money movement for participants in the ecosystem. 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 merchant 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 (U.S. GAAP). The Company consolidates its majority-owned and controlled entities, including 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. All significant intercompany accounts and transactions are eliminated in consolidation. The accompanying unaudited consolidated financial statements are presented in accordance with 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 U.S. GAAP. Reference should be made to the Visa Annual Report on Form 10-K for the year ended September 30, 2022 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 U.S. 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 revenues and expenses during the reporting period. These estimates may change as new events occur and additional information is obtained, and will be recognized in the period in which such changes occur. Future actual results could differ materially from these estimates. Recently Adopted Accounting Pronouncement. In March 2020, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2020-04, which provides optional expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships and other transactions that reference the London Interbank Offered Rate (LIBOR) or another reference rate expected to be discontinued because of reference rate reform. Subsequently, the FASB also issued amendments to this standard. The amendments in the ASU are effective upon issuance through December 31, 2024. During the quarter ended March 31, 2023, the Company adopted certain optional expedients provided in this ASU in relation to contract modifications and hedge accounting. The adoption did not have a material impact on the consolidated financial statements.

Note 4—U.S. and Europe Retrospective Responsibility Plans

U.S. Retrospective Responsibility Plan

Under the terms of the U.S. retrospective responsibility plan, the Company maintains an escrow account from which settlements of, or judgments in, certain litigation referred to as the “U.S. covered litigation” are paid. The accrual related to the U.S. covered litigation could be either higher or lower than the U.S. litigation escrow account balance. See Note 12—Legal Matters.

The following table presents the changes in the restricted cash equivalents—U.S. litigation escrow account:

Balance at end of period	$	1,616	$	882

(1)These payments are associated with the interchange multidistrict litigation. See Note 12—Legal Matters.

Europe Retrospective Responsibility Plan

Visa Inc., Visa International and Visa Europe are parties to certain existing and potential litigation relating to the setting of multilateral interchange fee rates in the Visa Europe territory (VE territory covered litigation). Under the terms of the Europe retrospective responsibility plan, the Company is entitled to recover certain losses resulting from VE territory covered litigation (VE territory covered losses) through a periodic adjustment to the class A common stock conversion rates applicable to the series B and C preferred stock. VE territory covered losses are recorded in a contra-equity account referred to as “right to recover for covered losses” within stockholders’ equity before the corresponding adjustment to the applicable conversion rate is effected. Adjustments to the conversion rate may be executed once in any six-month period unless a single, individual loss greater than €20 million is incurred, in which case, the six-month limitation does not apply. When the adjustment to the conversion rate is made, the amount previously recorded in “right to recover for covered losses” as contra-equity is then recorded against the book value of the preferred stock within stockholders’ equity.

The following table presents the activities related to VE territory covered losses in preferred stock and “right to recover for covered losses” within stockholders’ equity:


	Preferred Stock				Right to Recover for Covered Losses
	Series B		Series C
	(in millions)
Balance as of September 30, 2022	$	460	$	812	$	(35)

Recovery through conversion rate adjustment	(26)		(3)		29
Balance as of March 31, 2022	$	1,045	$	1,520	$	(120)

(1)VE territory covered losses incurred reflect settlements with merchants and additional legal costs. See Note 12—Legal Matters.

(2)Adjustment to right to recover for covered losses for the conversion rate adjustment differs from the actual recovered amount due to differences in foreign exchange rates between the time the losses were incurred and the subsequent recovery through the conversion rate adjustment.

The following table presents the as-converted value of the preferred stock available to recover VE territory covered losses compared to the book value of preferred stock recorded in stockholders’ equity within the Company’s consolidated balance sheets:


	March 31, 2023				September 30, 2022
	As-converted Value of Preferred Stock(1),(2)		Book Value of Preferred Stock(1)		As-converted Value of Preferred Stock(1),(3)		Book Value of Preferred Stock(1)

(1)Figures in the table may not recalculate exactly due to rounding. As-converted and book values are based on unrounded numbers.

(2)As of March 31, 2023, the as-converted value of preferred stock is calculated as the product of: (a) 2 million and 3 million shares of the series B and C preferred stock outstanding, respectively; (b) 2.958 and 3.634, the class A common stock conversion rate applicable to the series B and C preferred stock outstanding, respectively; and (c) $225.46, Visa’s class A common stock closing stock price.

(3)As of September 30, 2022, the as-converted value of preferred stock is calculated as the product of: (a) 2 million and 3 million shares of the series B and C preferred stock outstanding, respectively; (b) 2.971 and 3.645, the class A common stock conversion rate applicable to the series B and C preferred stock outstanding, respectively; and (c) $177.65, Visa’s class A common stock closing stock price.

Level 1 assets and liabilities. Money market funds, U.S. Treasury securities and marketable equity securities are classified as Level 1 within the fair value hierarchy, as fair value is based on unadjusted quoted prices in active markets for identical assets. The Company’s deferred compensation liability is measured at fair value based on marketable equity securities held under the deferred compensation plan.

Level 2 assets and liabilities. The fair value of U.S. government-sponsored debt securities, as provided by third-party pricing vendors, is based on quoted prices in active markets for similar, not identical, assets. Derivative instruments are valued using inputs that are observable in the market or can be derived principally from or corroborated by observable market data.

Equity Securities

The Company’s non-marketable equity securities are investments in privately held companies without readily determinable market values. These investments are measured at fair value on a non-recurring basis and are classified as Level 3 due to the absence of quoted market prices, the inherent lack of liquidity and the fact that inputs used to measure fair value are unobservable and require management’s judgment.

The following table summarizes the total carrying value of the Company’s non-marketable equity securities held as of March 31, 2023 including cumulative unrealized gains and losses:


	March 31, 2023
	(in millions)
Initial cost basis	$	754
Adjustments:
Upward adjustments	829
Downward adjustments (including impairment)	(438)
Carrying amount, end of period	$	1,145

Unrealized gains and losses included in the carrying value of the Company’s non-marketable equity securities still held as of March 31, 2023 and 2022 were as follows:

For the three months ended March 31, 2023 and 2022, the Company recognized net unrealized losses of $82 million and $156 million, respectively, on marketable and non-marketable equity securities still held as of quarter end. For the six months ended March 31, 2023 and 2022, the Company recognized net unrealized losses of $184 million and net unrealized gains of $16 million, respectively, on marketable and non-marketable equity securities still held as of quarter end.

Other Fair Value Disclosures

Debt. Debt instruments are measured at amortized cost on the Company’s consolidated balance sheets. The fair value of the debt instruments, as provided by third-party pricing vendors, is based on quoted prices in active markets for similar, not identical, assets. If measured at fair value in the financial statements, these instruments would be classified as Level 2 in the fair value hierarchy. As of March 31, 2023, the carrying value and estimated fair value of debt was $20.6 billion and $18.9 billion, respectively. As of September 30, 2022, the carrying value and estimated fair value of debt was $22.5 billion and $19.9 billion, respectively.

Other financial instruments not measured at fair value. As of March 31, 2023, the carrying values of settlement receivable and payable and customer collateral are an approximate fair value due to their generally short maturities. If measured at fair value in the financial statements, these financial instruments would be classified as Level 2 in the fair value hierarchy.

Non-financial assets. Certain non-financial assets such as goodwill, intangible assets and property, equipment and technology are subject to non-recurring fair value measurements if they are deemed to be impaired. The Company performed its annual impairment review of its indefinite-lived intangible assets and goodwill as of February 1, 2023, and concluded there was no impairment as of that date. No recent events or changes in circumstances indicated that impairment existed as of March 31, 2023

The entire disclosure for the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments as well as disclosures related to the fair value of non-financial assets and liabilities. Such disclosures about the financial instruments, assets, and liabilities would include: (1) the fair value of the required items together with their carrying amounts (as appropriate); (2) for items for which it is not practicable to estimate fair value, disclosure would include: (a) information pertinent to estimating fair value (including, carrying amount, effective interest rate, and maturity, and (b) the reasons why it is not practicable to estimate fair value; (3) significant concentrations of credit risk including: (a) information about the activity, region, or economic characteristics identifying a concentration, (b) the maximum amount of loss the entity is exposed to based on the gross fair value of the related item, (c) policy for requiring collateral or other security and information as to accessing such collateral or security, and (d) the nature and brief description of such collateral or security; (4) quantitative information about market risks and how such risks are managed; (5) for items measured on both a recurring and nonrecurring basis information regarding the inputs used to develop the fair value measurement; and (6) for items presented in the financial statement for which fair value measurement is elected: (a) information necessary to understand the reasons for the election, (b) discussion of the effect of fair value changes on earnings, (c) a description of [similar groups] items for which the election is made and the relation thereof to the balance sheet, the aggregate carrying value of items included in the balance sheet that are not eligible for the election; (7) all other required (as defined) and desired information.

Settlement Guarantee Management

Note 7—Settlement Guarantee Management

The Company indemnifies its clients for settlement losses suffered due to failure of any other client to fund its settlement obligations in accordance with the Visa operating rules. This indemnification creates settlement risk for the Company due to the difference in timing between the date of a payment transaction and the date of subsequent settlement.

Historically, the Company has experienced minimal losses as a result of its settlement risk guarantee. However, the Company’s future obligations, which could be material under its guarantees, are not determinable as they are dependent upon future events.

The Company’s settlement exposure is limited to the amount of unsettled Visa payment transactions at any point in time, which vary significantly day to day. During the six months ended March 31, 2023, the Company’s maximum daily settlement exposure was $123.5 billion and the average daily settlement exposure was $75.0 billion.

The Company maintains and regularly reviews global settlement risk policies and procedures to manage settlement exposure, which may require clients to post collateral if certain credit standards are not met. The Company held the following collateral to manage settlement exposure:


	March 31, 2023		September 30, 2022
	(in millions)
Restricted cash and restricted cash equivalents	$	2,739	$	2,342

Income Taxes	6 Months Ended
Income Taxes	Mar. 31, 2023
Income Tax Disclosure [Abstract]
Income Taxes	Note 11—Income Taxes For the three and six months ended March 31, 2023, the effective income tax rates were 19% and 18%, respectively, and for the three and six months ended March 31, 2022, the effective income tax rates were 20% and 19%, respectively. The difference in the effective tax rates is primarily due to a $142 million tax benefit related to prior years recognized during the six months ended March 31, 2023 due to the reassessment of an uncertain tax position as a result of new information obtained during an ongoing tax examination. During the three months ended March 31, 2023, the Company’s gross and net unrecognized tax benefits increased by $86 million and $26 million, respectively. During the six months ended March 31, 2023, the Company’s gross and net unrecognized tax benefits decreased by $22 million and $123 million, respectively. The change in unrecognized tax benefits is related to various tax positions across several jurisdictions. Additionally, for the six month period, the decrease in unrecognized tax benefits is primarily due to the reassessment mentioned above, partially offset by an increase in gross timing differences. The Company’s tax filings are subject to examination by U.S. federal, state and foreign taxing authorities. The timing and outcome of the final resolutions of the various ongoing income tax examinations are highly uncertain. It is not reasonably possible to estimate the increase or decrease in unrecognized tax benefits within the next twelve months.

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

Legal Matters

Note 12—Legal Matters

The Company is party to various legal and regulatory proceedings. Some of these proceedings involve complex claims that are subject to substantial uncertainties and unascertainable damages. For those proceedings where a loss is determined to be only reasonably possible or probable but not estimable, the Company has disclosed the nature of the claim. Additionally, unless otherwise disclosed below with respect to these proceedings, the Company cannot provide an estimate of the possible loss or range of loss. Although the Company believes that it has strong defenses for the litigation and regulatory proceedings described below, it could, in the future, incur judgments or fines or enter into settlements of claims that could have a material adverse effect on the Company’s financial position, results of operations or cash flows. From time to time, the Company may engage in settlement discussions or mediations with respect to one or more of its outstanding litigation matters, either on its own behalf or collectively with other parties.

The litigation accrual is an estimate and is based on management’s understanding of its litigation profile, the specifics of each case, advice of counsel to the extent appropriate and management’s best estimate of incurred loss as of the balance sheet date.

The following table summarizes the activity related to accrued litigation:


	Six Months Ended March 31,
	2023		2022
	(in millions)
Balance at beginning of period	$	1,456	$	983
Provision for uncovered legal matters	—		1
Provision for covered legal matters	352		150

Balance at end of period	$	1,602	$	769

Accrual Summary—U.S. Covered Litigation

Visa Inc., Visa U.S.A. and Visa International are parties to certain legal proceedings that are covered by the U.S. retrospective responsibility plan, which the Company refers to as the U.S. covered litigation. An accrual for the

U.S. covered litigation and a charge to the litigation provision are recorded when a loss is deemed to be probable and reasonably estimable. In making this determination, the Company evaluates available information, including but not limited to actions taken by the Company’s litigation committee. The total accrual related to the U.S. covered litigation could be either higher or lower than the escrow account balance. See further discussion below under U.S. Covered Litigation and Note 4—U.S. and Europe Retrospective Responsibility Plans.

The following table summarizes the accrual activity related to U.S. covered litigation:


	Six Months Ended March 31,
	2023		2022
	(in millions)
Balance at beginning of period	$	1,441	$	881
Provision for interchange multidistrict litigation	341		145

Payments for U.S. covered litigation	(201)		(262)
Balance at end of period	$	1,581	$	764

During the six months ended March 31, 2023, the Company recorded an additional accrual of $341 million and deposited $350 million into the U.S. litigation escrow account to address claims associated with the interchange multidistrict litigation. The U.S. covered litigation accrual balance is consistent with the Company’s best estimate of its share of a probable and reasonably estimable loss with respect to the U.S. covered litigation. While this estimate is consistent with the Company’s view of the current status of the litigation, the probable and reasonably estimable loss or range of such loss could materially vary based on developments in the litigation. The Company will continue to consider and reevaluate this estimate in light of the substantial uncertainties with respect to the litigation. The Company is unable to estimate a potential loss or range of loss, if any, at trial if negotiated resolutions cannot be reached.

Accrual Summary—VE Territory Covered Litigation

Visa Inc., Visa International and Visa Europe are parties to certain legal proceedings that are covered by the Europe retrospective responsibility plan. Unlike the U.S. retrospective responsibility plan, the Europe retrospective responsibility plan does not have an escrow account that is used to fund settlements or judgments. The Company is entitled to recover VE territory covered losses through periodic adjustments to the conversion rates applicable to the series B and C preferred stock. An accrual for the VE territory covered losses and a reduction to stockholders’ equity will be recorded when the loss is deemed to be probable and reasonably estimable. See further discussion below under VE Territory Covered Litigation and Note 4—U.S. and Europe Retrospective Responsibility Plans.

The following table summarizes the accrual activity related to VE territory covered litigation:


	Six Months Ended March 31,

As of the filing date, Visa has settled the claims asserted by over 175 Merchants, and there are approximately 900 Merchants with outstanding claims. In addition, over 30 additional Merchants have threatened to commence similar proceedings. Standstill agreements have been entered into with respect to some of those threatened Merchant claims, several of which have been settled.

Summary of Significant Accounting Policies (Policies)	6 Months Ended
Summary of Significant Accounting Policies (Policies)	Mar. 31, 2023
Accounting Policies [Abstract]
Consolidation and basis of presentation	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 (U.S. GAAP). The Company consolidates its majority-owned and controlled entities, including 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. All significant intercompany accounts and transactions are eliminated in consolidation. The accompanying unaudited consolidated financial statements are presented in accordance with 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 U.S. GAAP. Reference should be made to the Visa Annual Report on Form 10-K for the year ended September 30, 2022 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	Use of estimates. The preparation of the accompanying unaudited consolidated financial statements in conformity with U.S. 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 revenues and expenses during the reporting period. These estimates may change as new events occur and additional information is obtained, and will be recognized in the period in which such changes occur. Future actual results could differ materially from these estimates.
Recently Adopted Accounting Pronouncement	Recently Adopted Accounting Pronouncement. In March 2020, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2020-04, which provides optional expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships and other transactions that reference the London Interbank Offered Rate (LIBOR) or another reference rate expected to be discontinued because of reference rate reform. Subsequently, the FASB also issued amendments to this standard. The amendments in the ASU are effective upon issuance through December 31, 2024. During the quarter ended March 31, 2023, the Company adopted certain optional expedients provided in this ASU in relation to contract modifications and hedge accounting. The adoption did not have a material impact on the consolidated financial statements.
