The computation includes approximately 3 million common stock equivalents for the three and nine months ended June 30, 2018, and 4 million and 5 million common stock equivalents for the three and nine months ended June 30, 2017, respectively, because their effect would be dilutive. The computation excludes less than 1 million and 1 million of common stock equivalents for the three and nine months ended June 30, 2018, respectively, and less than 1 million and 3 million of common stock equivalents for the three and nine months ended June 30, 2017, respectively, because their effect would have been anti-dilutive.

Summary of Significant Accounting Policies
Note 1—Summary of Significant Accounting Policies
Organization. Visa Inc. (“Visa” or the “Company”) is a global payments technology company that enables fast, secure and reliable electronic payments across more than 200 countries and territories. Visa and its wholly-owned consolidated subsidiaries, including Visa U.S.A. Inc. (“Visa U.S.A.”), Visa International Service Association (“Visa International”), Visa Worldwide Pte. Limited, Visa Europe Limited (“Visa Europe”), Visa Canada Corporation, Visa Technology & Operations LLC and CyberSource Corporation, operate one of the world’s largest retail electronic payments networks — VisaNet — which facilitates authorization, clearing and settlement of payment transactions and enables the Company to provide its financial institution and merchant clients a wide range of products, platforms and value-added services. VisaNet also offers fraud protection for account holders and assured payment for merchants. Visa is not a bank and does not issue cards, extend credit or set rates and fees for account holders on 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 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 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 U.S. GAAP. Reference should be made to the Visa Annual Report on Form 10-K for the year ended September 30, 2017 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.
Recently Issued and Adopted Accounting Pronouncements.
In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2014-09, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of goods or services to customers. The ASU replaces existing revenue recognition guidance in U.S. GAAP. Subsequently, the FASB also issued a series of amendments to the new revenue standard. The Company will adopt the standard effective October 1, 2018, and expects to adopt the standard using the modified retrospective transition method. The Company expects that the new standard will primarily impact recognition timing for certain fixed incentives and price discounts provided to clients, and the classification of certain client incentives between contra revenues and operating expenses. The impact of the new standard to future financial results is unknowable as it is not possible to estimate the impact to the recognition of new customer contracts which may be executed in future periods. The Company has completed an assessment of its existing customer contracts through June 30, 2018. Application of the new standard to consolidated financial statements for the first three quarters of fiscal 2018 would not have resulted in a material impact. The Company will continue to assess the impact of the new standard as new customer contracts are executed going forward.
In March 2016, the FASB issued ASU 2016-05, which clarifies that a change in the counterparty to a derivative instrument that has been designated as the hedging instrument under Topic 815, Derivatives and Hedging, does not, in and of itself, require dedesignation of that hedging relationship provided that all other hedge accounting criteria continue to be met. The Company adopted the standard effective October 1, 2017. The adoption did not have a material impact on the consolidated financial statements.
In March 2016, the FASB issued ASU 2016-06, which clarifies the requirements for assessing whether contingent call/put options that can accelerate the payment of principal on debt instruments are clearly and closely related to their debt hosts. An entity performing the assessment is required to assess the embedded call/put options solely in accordance with a four-step decision sequence. The Company adopted the standard effective October 1, 2017. The adoption did not have a material impact on the consolidated financial statements.
In March 2016, the FASB issued ASU 2016-07, which eliminates the requirement that an entity retroactively adopt the equity method of accounting if an investment qualifies for use of the equity method as a result of an increase in the level of ownership or degree of influence. The equity method investor is required to add the cost of acquiring the additional interest in the investee to the current basis of the investor’s previously held interest and adopt the equity method of accounting as of the date the investment becomes qualified for equity method accounting. The Company adopted the standard effective October 1, 2017. The adoption did not have a material impact on the consolidated financial statements.
In February 2018, the FASB issued ASU 2018-02, which allows a reclassification from accumulated other comprehensive income to retained earnings for adjustments to tax effects that were originally recorded in other comprehensive income due to changes in the U.S. federal corporate income tax rate resulting from the enactment of the U.S. tax reform legislation, commonly referred to as the Tax Cuts and Jobs Act (the “Tax Act”). The Company will adopt the standard effective October 1, 2019. The adoption is not expected to have a material impact on the consolidated financial statements.
In March 2018, the FASB issued ASU 2018-05 to insert the SEC’s interpretive guidance from Staff Accounting Bulletin No. 118 into the income tax accounting codification under U.S. GAAP. The ASU permits companies to use provisional amounts for certain income tax effects of the Tax Act during a one-year measurement period. The provisional accounting impacts for the Company may change in future reporting periods until the accounting analysis is finalized, which will occur no later than the first quarter of fiscal 2019.

Retrospective Responsibility Plan [Abstract]  
U.S. and Europe Retrospective Responsibility Plans
Note 2—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 escrow funds are held in money market investments along with interest income earned, less applicable taxes and are classified as restricted cash on the consolidated balance sheets. During the nine months ended June 30, 2018, the Company deposited $600 million into the litigation escrow account, and paid $150 million from the litigation escrow account. The balance of the escrow account was $1.5 billion at June 30, 2018 and $1.0 billion at September 30, 2017. See Note 11—Legal Matters.
The accrual related to the U.S. covered litigation could be either higher or lower than the litigation escrow account balance. During the nine months ended June 30, 2018, the Company recorded an additional accrual of $600 million for the U.S. covered litigation to address claims associated with the interchange multidistrict litigation. See Note 11—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 (the “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 (the “VE territory covered losses”) through a periodic adjustment to the class A common stock conversion rates applicable to the UK&I and Europe preferred stock. VE territory covered losses are recorded in “right to recover for covered losses” within 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.
During the three and nine months ended June 30, 2018, the Company recovered $6 million and $56 million, respectively, of VE territory covered losses through adjustments to the class A common stock conversion rates applicable to the UK&I and Europe preferred stock. The conversion rates applicable to the UK&I and Europe preferred stock were reduced from 13.077 and 13.948, respectively, at September 30, 2017 to 12.955 and 13.888, respectively, at June 30, 2018.
The following table sets forth the activities related to VE territory covered losses in preferred stock and “right to recover for covered losses” within equity during the nine months ended June 30, 2018. VE territory covered losses incurred reflect settlements with merchants and additional legal costs. See Note 11—Legal Matters.

There were no transfers between Level 1 and Level 2 assets during the nine months ended June 30, 2018.
Level 1 assets measured at fair value on a recurring basis. Money market funds, publicly-traded equity securities and U.S. Treasury securities are classified as Level 1 within the fair value hierarchy, as fair value is based on quoted prices in active markets.
Level 2 assets and liabilities measured at fair value on a recurring basis. 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. The pricing data obtained from outside sources is reviewed internally for reasonableness, compared against benchmark quotes from independent pricing sources, then confirmed or revised accordingly. Foreign exchange derivative instruments are valued using inputs that are observable in the market or can be derived principally from or corroborated by observable market data. There were no substantive changes to the valuation techniques and related inputs used to measure fair value during the nine months ended June 30, 2018.
Assets Measured at Fair Value on a Non-recurring Basis
Non-marketable equity investments and investments accounted for under the equity method. These investments 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. When certain events or circumstances indicate that impairment may exist, the Company revalues the investments using various assumptions, including the financial metrics and ratios of comparable public companies. There were no significant impairments during the nine months ended June 30, 2018 or 2017. These investments totaled $125 million and $94 million at June 30, 2018 and September 30, 2017, respectively, and are classified in other assets on the consolidated balance sheets.
Non-financial assets and liabilities. Long-lived assets such as goodwill, indefinite-lived intangible assets, finite-lived intangible assets, and property, equipment and technology are considered non-financial assets. The Company does not have any non-financial liabilities measured at fair value on a non-recurring basis. Finite-lived intangible assets primarily consist of customer relationships, trade names and reseller relationships, all of which were obtained through acquisitions.
If the Company were required to perform a quantitative assessment for impairment testing of goodwill and indefinite-lived intangible assets, the fair values would generally be estimated using an income approach. As the assumptions employed to measure these assets on a non-recurring basis are based on management’s judgment using internal and external data, these fair value determinations are classified as Level 3 in the fair value hierarchy. The Company completed its annual impairment review of its indefinite-lived intangible assets and goodwill as of February 1, 2018, and concluded that there was no impairment. No recent events or changes in circumstances indicate that impairment existed at June 30, 2018.
Other Fair Value Disclosures
Long-term debt. Debt instruments are measured at amortized cost on the Company’s unaudited consolidated balance sheet at June 30, 2018. 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. The pricing data obtained from outside sources is reviewed internally for reasonableness, compared against benchmark quotes from independent pricing sources, then confirmed or revised accordingly. If measured at fair value in the financial statements, these instruments would be classified as Level 2 in the fair value hierarchy.

Other financial instruments not measured at fair value. The following financial instruments are not measured at fair value on the Company’s unaudited consolidated balance sheet at June 30, 2018, but disclosure of their fair values is required: time deposits recorded in prepaid expenses and other current assets, settlement receivable and payable, and customer collateral. The estimated fair value of such instruments at June 30, 2018 approximates their carrying 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.
Investments
Available-for-sale investment securities. The Company had $175 million in gross unrealized gains and $16 million in gross unrealized losses at June 30, 2018. There were $120 million in gross unrealized gains and $4 million in gross unrealized losses at September 30, 2017. For the three and nine months ended June 30, 2018, the Company recorded gross realized gains on the sale of investment securities of $32 million and $64 million, respectively. There were no gross realized gains on the sale of investment securities recognized during the same periods in 2017. A majority of the Company’s long-term available-for-sale investment securities have stated maturities between one to five years.

Senior Notes
On October 11, 2017, the Company redeemed all of the $1.75 billion principal amount outstanding of the 2017 Notes. The redemption was funded with net proceeds from new fixed-rate senior notes issued by the Company in September 2017. As a result of this redemption, the Company recorded a $1 million loss on extinguishment of debt during the nine months ended June 30, 2018.
The Company recognized interest expense, as non-operating expense, for the senior notes of $137 million and $413 million for the three and nine months ended June 30, 2018, respectively, as compared to $125 million and $376 million for the same periods in 2017.

Settlement Guarantee Management [Abstract]  
Settlement Guarantee Management
Note 5—Settlement Guarantee Management
The Company indemnifies its clients for settlement losses suffered due to failure of any other clients to fund its settlement obligations in accordance with the Visa 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. The Company’s settlement exposure is limited to the amount of unsettled Visa payment transactions at any point in time. The Company requires certain clients that do not meet its credit standards to post collateral to offset potential losses from their estimated unsettled transactions. The Company’s estimated maximum settlement exposure was $73.2 billion during the three months ended June 30, 2018, compared to $67.7 billion during the three months ended September 30, 2017. Of these amounts, $2.8 billion was covered by collateral at June 30, 2018 and September 30, 2017. The total available collateral balances presented in the table below were greater than the settlement exposure covered by customer collateral held due to instances in which the available collateral exceeded the total settlement exposure for certain financial institutions at each date presented.
The Company maintained collateral as follows:

Cash collateral held by Visa Europe is not included on the Company’s consolidated balance sheets as its clients retain beneficial ownership and the cash is only accessible to the Company in the event of default by the client on its settlement obligations.
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 class B to class A common stock conversion rate is presented on a rounded basis. Conversion calculations for dividend payments are based on a conversion rate rounded to the tenth decimal.
Reduction in as-converted shares. During the nine months ended June 30, 2018, total as-converted class A common stock was reduced by 52 million shares at an average price of $120.37 per share. Of the 52 million shares, 47 million were repurchased in the open market using $5.6 billion of operating cash on hand. Additionally, in June 2018, the Company deposited $600 million of operating cash into the litigation escrow account previously established under the U.S. retrospective responsibility plan. Also, the Company recovered $56 million of VE territory covered losses in accordance with the Europe retrospective responsibility plan during the nine months ended June 30, 2018. The deposit and recovery have the same economic effect on earnings per share as repurchasing the Company’s class A common stock, because they reduce the class B common stock conversion rate and the UK&I and Europe preferred stock conversion rates and consequently reduce the as-converted class A common stock share count. See Note 2—U.S. and Europe Retrospective Responsibility Plans.

Earnings Per Share
Note 8—Earnings Per Share
Basic earnings per share is computed by dividing net income available to each class by the weighted-average number of shares of common stock outstanding and participating securities during the period. Net income is allocated to each class of common stock and participating securities based on its proportional ownership on an as-converted basis. The weighted-average number of shares of each class of common stock outstanding reflects changes in ownership over the periods presented. See Note 7—Stockholders' Equity.
Diluted earnings per share is computed by dividing net income available by the weighted-average number of shares of common stock outstanding, participating securities and, if dilutive, potential class A common stock equivalent shares outstanding during the period. Dilutive class A common stock equivalents may consist of: (1) shares of class A common stock issuable upon the conversion of UK&I and Europe preferred stock and class B and C common stock based on the conversion rates in effect through the period, and (2) incremental shares of class A common stock calculated by applying the treasury stock method to the assumed exercise of employee stock options, the assumed purchase of stock under the Employee Stock Purchase Plan and the assumed vesting of unearned performance shares.

Figures in the table may not recalculate exactly due to rounding. Earnings per share is calculated based on unrounded numbers.
(2) 
Net income is allocated based on proportional ownership on an as-converted basis. The weighted-average number of shares of as-converted class B common stock used in the income allocation was 405 million for the three and nine months ended June 30, 2018 and 2017. The weighted-average number of shares of as-converted class C common stock used in the income allocation was 49 million and 50 million for the three and nine months ended June 30, 2018, respectively, and 54 million and 60 million for the three and nine months ended June 30, 2017, respectively. The weighted-average number of shares of preferred stock included within participating securities was 32 million of as-converted UK&I preferred stock for the three and nine months ended June 30, 2018, and 33 million and 34 million of as-converted UK&I preferred stock for the three and nine months ended June 30, 2017, respectively. The weighted-average number of shares of preferred stock included within participating securities was 44 million of as-converted Europe preferred stock for the three and nine months ended June 30, 2018 and 2017.
(3) 
Weighted-average diluted shares outstanding are calculated on an as-converted basis and include incremental common stock equivalents, as calculated under the treasury stock method. The computation includes approximately 3 million common stock equivalents for the three and nine months ended June 30, 2018, and 4 million and 5 million common stock equivalents for the three and nine months ended June 30, 2017, respectively, because their effect would be dilutive. The computation excludes less than 1 million and 1 million of common stock equivalents for the three and nine months ended June 30, 2018, respectively, and less than 1 million and 3 million of common stock equivalents for the three and nine months ended June 30, 2017, respectively, because their effect would have been anti-dilutive.
(4) 
Participating securities include preferred stock outstanding and unvested share-based payment awards that contain non-forfeitable rights to dividends or dividend equivalents, such as the Company’s UK&I and Europe preferred stock, restricted stock awards, restricted stock units and earned performance-based shares. Participating securities’ income is allocated based on the weighted-average number of shares of as-converted stock.

Income Tax Disclosure [Abstract]  
Income Taxes
Note 10—Income Taxes
The effective income tax rates were 17% and 20% for the three and nine months ended June 30, 2018, respectively, and 29% and 47% for the three and nine months ended June 30, 2017, respectively. The effective tax rates for the three and nine months ended June 30, 2018 differ from the effective tax rates in the same prior-year periods primarily due to:
an $81 million benefit due to a non-recurring audit settlement during the quarter ended June 30, 2018;
an $80 million benefit due to a non-recurring audit settlement during the quarter ended March 31, 2018;
the effects of the Tax Act, enacted during the quarter ended December 31, 2017, as discussed below; and
the absence of the following items related to the Visa Europe reorganization recorded during the quarter ended March 31, 2017:
a $1.5 billion non-recurring, non-cash income tax provision primarily related to the elimination of deferred tax balances originally recognized upon the acquisition of Visa Europe; and
a $71 million one-time tax benefit related to the Visa Foundation’s receipt of Visa Inc. shares, previously recorded by Visa Europe as treasury stock.
The Tax Act, enacted on December 22, 2017, transitions the U.S. tax system to a new territorial system and lowers the statutory federal corporate income tax rate from 35% to 21%. The reduction of the statutory federal corporate tax rate to 21% became effective on January 1, 2018. In fiscal 2018, the Company’s statutory federal corporate rate is a blended rate of 24.5%, which will be reduced to 21% in fiscal 2019 and thereafter.
As a result of the reduction in the federal corporate tax rate, the Company remeasured its net deferred tax liabilities as of the enactment date of the Tax Act. The deferred tax remeasurement resulted in a one-time, non-cash tax benefit estimated to be approximately $1.1 billion, recorded in the three months ended December 31, 2017.
In transitioning to the new territorial tax system, the Tax Act requires the Company to include certain untaxed foreign earnings of non-U.S. subsidiaries in its fiscal 2018 taxable income. Such foreign earnings are subject to a one-time tax at 15.5% on the amount held in cash or cash equivalents, and at 8% on the remaining non-cash amount. The 15.5% and 8% tax, collectively referred to as the “transition tax”, was estimated to be $1.1 billion, and was recorded in the three months ended December 31, 2017. The Company intends to elect to pay the transition tax over a period of eight years as permitted by the Tax Act.
The above-mentioned accounting impacts of the deferred tax remeasurement and transition tax are provisional, based on currently available information and technical guidance on the interpretations of the new law. The Company continues to obtain and analyze additional information and guidance as they become available to complete the accounting for the tax impacts of the Tax Act. Additional information currently unavailable that is needed to complete the analysis includes, but is not limited to, foreign tax returns and foreign tax documentation for the computation of foreign tax credits, the final determination of the untaxed foreign earnings subject to the transition tax, and the final determination of the net deferred tax liabilities subject to remeasurement. The provisional accounting impacts may change in future reporting periods until the accounting analysis is finalized, which will occur no later than the first quarter of fiscal 2019, as permitted by ASU 2018-05.
The Tax Act also introduces several tax provisions, including:
Tax on global intangible low-tax income, which, in general, is determined annually based on the Company’s aggregate foreign subsidiaries’ income in excess of certain qualified business asset investment return. This provision is effective for the Company on October 1, 2018. The Company needs additional information to complete its analysis on whether to adopt an accounting policy to account for the tax effects of global intangible low-tax income in the period that it is subject to such tax, or to provide deferred taxes for book and tax basis differences that, upon reversal, may be subject to such tax. Hence, the Company has not recorded any tax on global intangible low-tax income in the nine months ended June 30, 2018. The Company will make an accounting policy election no later than the first quarter of fiscal 2019.
Base erosion and anti-abuse tax, which, in general, functions like a minimum tax that partially disallows deductions for certain related party transactions. This new minimum tax is determined on a year-by-year basis, and this provision is effective for the Company on October 1, 2018. Hence, no base erosion anti-abuse tax has been recorded in the nine months ended June 30, 2018.
Deduction for foreign-derived intangible income, which, in general, allows a deduction of certain intangible income derived from serving foreign markets. This provision is effective for the Company on October 1, 2018. Hence, the Company has not recorded the impact of this provision in the nine months ended June 30, 2018.
Other new tax provisions, which disallow certain deductions related to entertainment expenses, fringe benefits provided to employees, executive compensation, and fines or penalties or similar payments to governments. The Company has recorded provisional amounts for the tax effects of these new provisions in the nine months ended June 30, 2018, based on information currently available. The provisional amounts may change in future reporting periods when additional information is obtained and analyzed, which will occur no later than the first quarter of fiscal 2019.
During the three and nine months ended June 30, 2018, the Company’s gross unrecognized tax benefits increased by $244 million and $237 million, respectively. The Company’s net unrecognized tax benefits that, if recognized, would favorably impact the effective tax rate increased by $69 million and $73 million during the three and nine months ended June 30, 2018, respectively. The changes in unrecognized tax benefits are primarily related to various tax positions across several jurisdictions. During the three and nine months ended June 30, 2018 and 2017, there were no significant changes in interest and penalties related to uncertain tax positions.
The Company’s tax filings are subject to examination by the 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.

Legal Matters [Abstract]  
Legal Matters
Note 11—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. Accordingly, except as disclosed, the Company has not established reserves or ranges of possible loss related to these proceedings, as at this time in the proceedings, the matters do not relate to a probable loss and/or the amount or range of losses are not reasonably estimable. 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.

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. See further discussion below under U.S. Covered Litigation and Note 2—U.S. and Europe Retrospective Responsibility Plans. 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 litigation committee. The total accrual related to the U.S. covered litigation could be either higher or lower than the escrow account balance.

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 UK&I preferred stock and Europe 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 2—U.S. and Europe Retrospective Responsibility Plans.

U.S. Covered Litigation
Interchange Multidistrict Litigation (MDL) – Putative Class Actions
Defendants Visa, MasterCard, and certain U.S. financial institutions have reached an agreement in principle with plaintiffs purporting to act on behalf of the putative Damages Class to resolve all Damages Class claims. The agreement to resolve these claims is subject to negotiation of a full written settlement agreement, and such negotiations are ongoing. Discussions with plaintiffs purporting to act on behalf of the Injunctive Relief Class are ongoing.
The Company believes at this stage that some loss resulting from the Damages Class claims is probable and a range of loss is reasonably estimable. On June 28, 2018, the Company deposited an additional $600 million into its covered litigation escrow account. During the nine months ended June 30, 2018, the Company increased the U.S. covered litigation accrual to $1.43 billion. The balance of $1.43 billion is consistent with the Company’s estimate of its share of the lower end of a probable and reasonably estimable loss with respect to U.S. covered litigation. While this estimate is consistent with the Company’s view of the current status of discussions, the probable and reasonably estimable loss or range of such loss could materially vary if settlements cannot be reached. The Company will continue to consider and reevaluate this estimate in light of the substantial uncertainties and mediation obstacles that persist. The Company is unable to estimate a potential loss or range of loss, if any, at trial if negotiated resolutions cannot be reached.
Interchange Multidistrict Litigation (MDL) – Individual Merchant Actions
A number of individual merchant actions previously filed have been settled, and remain settled. As of the filing date, Visa has reached settlement agreements with individual merchants representing approximately 51% of the Visa-branded payment card sales volume of merchants who opted out of the 2012 Settlement Agreement.
VE Territory Covered Litigation
UK Merchant Litigation
Since July 2013, in excess of 400 Merchants (the capitalized term “Merchant,” when used in this section, means a merchant together with subsidiary/affiliate companies that are party to the same claim) have commenced proceedings against Visa Europe, Visa Inc. and Visa International relating to interchange rates in Europe. They seek damages for alleged anti-competitive conduct in relation to one or more of the following types of interchange fees for credit and debit card transactions: UK domestic, Irish domestic, other European domestic, intra-European Economic Area and/or other inter-regional. As of the filing date, Visa Europe, Visa Inc. and Visa International have settled the claims asserted by over 75 Merchants, leaving more than 300 Merchants with outstanding claims.
In November 2016, a trial commenced relating to claims filed by a number of Merchants. All of these Merchants except one settled before the trial concluded in March 2017. On November 30, 2017, the court found that Visa’s UK domestic interchange was not restrictive of competition and dismissed the remaining claim. A further judgment was published on February 23, 2018, which did not change the court’s November 30, 2017 ruling but found that Visa’s UK domestic interchange would not have been exemptible under applicable law if it restricted competition. The remaining Merchant lodged an appeal and the matter was heard by the Court of Appeal in April 2018 in connection with two MasterCard cases. On July 4, 2018, the Court of Appeal overturned the lower court’s rulings of November 30, 2017 and February 23, 2018, finding that Visa’s UK domestic interchange restricted competition and the question of whether Visa’s UK domestic interchange was exempt from the finding of restriction under applicable law had been incorrectly decided. The Court of Appeal remitted the claim to the lower court to reconsider the exemption issue and the assessment of damages. Visa intends to seek permission to appeal aspects of the Court of Appeal’s judgment.
In addition, over 30 additional Merchants have threatened to commence similar proceedings. Standstill agreements have been entered into with respect to some of those Merchants’ claims. While the amount of interchange being challenged could be substantial, these claims have not yet been filed and their full scope is not yet known. The Company has learned that several additional European entities have indicated that they may also bring similar claims and the Company anticipates additional claims in the future.
Other Litigation
European Commission Proceedings
Inter-regional Interchange Investigation. Visa responded in writing to the revised Supplementary Statement of Objections in November 2017 and an oral hearing was held in February 2018. Visa continues to cooperate with the European Commission (EC) in its investigation.
Further, the debit and credit commitments previously entered into to settle certain aspects of the EC’s investigation have now both expired. However, the European Union rates on which those commitments were applied remain subject to limits imposed by the European Interchange Fee Regulation.
Canadian Competition Proceedings
Merchant Litigation. The court in Quebec held a class certification hearing in November 2017 and reserved decision.
Courts in all five Canadian provinces have preliminarily approved Visa’s settlement with merchant class plaintiffs, and hearings on final approval are scheduled from June through September 2018. On July 13, the court in British Columbia provided final approval of the settlement.
New Mexico Attorney General
The parties reached a settlement agreement and the case was dismissed on April 10, 2018.
EMV Chip Liability Shift
On March 11, 2018, the court denied the plaintiffs’ motion for class certification without prejudice. Plaintiffs subsequently filed a renewed motion for class certification on July 16, 2018.
Kroger
On February 6, 2018, Kroger sought leave to file a second amended complaint. The parties have stipulated that the litigation, including consideration of that motion, be stayed until August 5, 2018.
Nuts for Candy
On March 6, 2018, the court denied Visa’s motion for summary adjudication of Nuts for Candy’s California unfair business statute claims. On April 2, 2018, Visa filed a petition for writ of mandate to the California Court of Appeal seeking to overturn the lower court’s decision and stay the case, which was subsequently denied. On May 14, 2018, Nuts for Candy moved for class certification.
Black Card
On December 28, 2017, Black Card LLC (“Black Card”) filed a lawsuit against Visa Inc., Visa U.S.A. Inc., and certain Visa member financial institutions in the U.S. District Court for the Western District of Wisconsin. The complaint alleged that defendants conspired to impede Black Card’s business in violation of Section 1 of the Sherman Act and fraudulently concealed their conduct. Black Card sought treble damages, post-judgment interest, and attorneys’ fees. On February 8, 2018, Black Card voluntarily dismissed its lawsuit in the U.S. District Court for the Western District of Wisconsin without prejudice.
This action followed a lawsuit filed by Black Card in the U.S. District Court for the District of Wyoming in February 2015 relating to a contractual dispute. The District Court in Wyoming granted Visa’s motions for summary judgment and the matter was dismissed. Black Card appealed this decision to the U.S. Court of Appeals for the Tenth Circuit on May 10, 2017, and the appellate court held a hearing on March 22, 2018 and reserved decision.

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 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 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 U.S. GAAP. Reference should be made to the Visa Annual Report on Form 10-K for the year ended September 30, 2017 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.
Recently issued and adopted accounting pronouncements
Recently Issued and Adopted Accounting Pronouncements.
In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2014-09, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of goods or services to customers. The ASU replaces existing revenue recognition guidance in U.S. GAAP. Subsequently, the FASB also issued a series of amendments to the new revenue standard. The Company will adopt the standard effective October 1, 2018, and expects to adopt the standard using the modified retrospective transition method. The Company expects that the new standard will primarily impact recognition timing for certain fixed incentives and price discounts provided to clients, and the classification of certain client incentives between contra revenues and operating expenses. The impact of the new standard to future financial results is unknowable as it is not possible to estimate the impact to the recognition of new customer contracts which may be executed in future periods. The Company has completed an assessment of its existing customer contracts through June 30, 2018. Application of the new standard to consolidated financial statements for the first three quarters of fiscal 2018 would not have resulted in a material impact. The Company will continue to assess the impact of the new standard as new customer contracts are executed going forward.
In March 2016, the FASB issued ASU 2016-05, which clarifies that a change in the counterparty to a derivative instrument that has been designated as the hedging instrument under Topic 815, Derivatives and Hedging, does not, in and of itself, require dedesignation of that hedging relationship provided that all other hedge accounting criteria continue to be met. The Company adopted the standard effective October 1, 2017. The adoption did not have a material impact on the consolidated financial statements.
In March 2016, the FASB issued ASU 2016-06, which clarifies the requirements for assessing whether contingent call/put options that can accelerate the payment of principal on debt instruments are clearly and closely related to their debt hosts. An entity performing the assessment is required to assess the embedded call/put options solely in accordance with a four-step decision sequence. The Company adopted the standard effective October 1, 2017. The adoption did not have a material impact on the consolidated financial statements.
In March 2016, the FASB issued ASU 2016-07, which eliminates the requirement that an entity retroactively adopt the equity method of accounting if an investment qualifies for use of the equity method as a result of an increase in the level of ownership or degree of influence. The equity method investor is required to add the cost of acquiring the additional interest in the investee to the current basis of the investor’s previously held interest and adopt the equity method of accounting as of the date the investment becomes qualified for equity method accounting. The Company adopted the standard effective October 1, 2017. The adoption did not have a material impact on the consolidated financial statements.
In February 2018, the FASB issued ASU 2018-02, which allows a reclassification from accumulated other comprehensive income to retained earnings for adjustments to tax effects that were originally recorded in other comprehensive income due to changes in the U.S. federal corporate income tax rate resulting from the enactment of the U.S. tax reform legislation, commonly referred to as the Tax Cuts and Jobs Act (the “Tax Act”). The Company will adopt the standard effective October 1, 2019. The adoption is not expected to have a material impact on the consolidated financial statements.
In March 2018, the FASB issued ASU 2018-05 to insert the SEC’s interpretive guidance from Staff Accounting Bulletin No. 118 into the income tax accounting codification under U.S. GAAP. The ASU permits companies to use provisional amounts for certain income tax effects of the Tax Act during a one-year measurement period. The provisional accounting impacts for the Company may change in future reporting periods until the accounting analysis is finalized, which will occur no later than the first quarter of fiscal 2019.

(1) 
Figures in the table may not recalculate exactly due to rounding. Earnings per share is calculated based on unrounded numbers.
(2) 
Net income is allocated based on proportional ownership on an as-converted basis. The weighted-average number of shares of as-converted class B common stock used in the income allocation was 405 million for the three and nine months ended June 30, 2018 and 2017. The weighted-average number of shares of as-converted class C common stock used in the income allocation was 49 million and 50 million for the three and nine months ended June 30, 2018, respectively, and 54 million and 60 million for the three and nine months ended June 30, 2017, respectively. The weighted-average number of shares of preferred stock included within participating securities was 32 million of as-converted UK&I preferred stock for the three and nine months ended June 30, 2018, and 33 million and 34 million of as-converted UK&I preferred stock for the three and nine months ended June 30, 2017, respectively. The weighted-average number of shares of preferred stock included within participating securities was 44 million of as-converted Europe preferred stock for the three and nine months ended June 30, 2018 and 2017.
(3) 
Weighted-average diluted shares outstanding are calculated on an as-converted basis and include incremental common stock equivalents, as calculated under the treasury stock method. The computation includes approximately 3 million common stock equivalents for the three and nine months ended June 30, 2018, and 4 million and 5 million common stock equivalents for the three and nine months ended June 30, 2017, respectively, because their effect would be dilutive. The computation excludes less than 1 million and 1 million of common stock equivalents for the three and nine months ended June 30, 2018, respectively, and less than 1 million and 3 million of common stock equivalents for the three and nine months ended June 30, 2017, respectively, because their effect would have been anti-dilutive.
(4) 
Participating securities include preferred stock outstanding and unvested share-based payment awards that contain non-forfeitable rights to dividends or dividend equivalents, such as the Company’s UK&I and Europe preferred stock, restricted stock awards, restricted stock units and earned performance-based shares. Participating securities’ income is allocated based on the weighted-average number of shares of as-converted stock.

[1] Net income is allocated based on proportional ownership on an as-converted basis. The weighted-average number of shares of as-converted class B common stock used in the income allocation was 405 million for the three and nine months ended June 30, 2018 and 2017. The weighted-average number of shares of as-converted class C common stock used in the income allocation was 49 million and 50 million for the three and nine months ended June 30, 2018, respectively, and 54 million and 60 million for the three and nine months ended June 30, 2017, respectively. The weighted-average number of shares of preferred stock included within participating securities was 32 million of as-converted UK&I preferred stock for the three and nine months ended June 30, 2018, and 33 million and 34 million of as-converted UK&I preferred stock for the three and nine months ended June 30, 2017, respectively. The weighted-average number of shares of preferred stock included within participating securities was 44 million of as-converted Europe preferred stock for the three and nine months ended June 30, 2018 and 2017.
[2] Figures in the table may not recalculate exactly due to rounding. Earnings per share is calculated based on unrounded numbers.
[3] Weighted-average diluted shares outstanding are calculated on an as-converted basis and include incremental common stock equivalents, as calculated under the treasury stock method. The computation includes approximately 3 million common stock equivalents for the three and nine months ended June 30, 2018, and 4 million and 5 million common stock equivalents for the three and nine months ended June 30, 2017, respectively, because their effect would be dilutive. The computation excludes less than 1 million and 1 million of common stock equivalents for the three and nine months ended June 30, 2018, respectively, and less than 1 million and 3 million of common stock equivalents for the three and nine months ended June 30, 2017, respectively, because their effect would have been anti-dilutive.
[4] Participating securities include preferred stock outstanding and unvested share-based payment awards that contain non-forfeitable rights to dividends or dividend equivalents, such as the Company’s UK&I and Europe preferred stock, restricted stock awards, restricted stock units and earned performance-based shares. Participating securities’ income is allocated based on the weighted-average number of shares of as-converted stock.
