This Quarterly Report on Form 10-Q includes market share and industry data that we obtained from industry publications and surveys, reports of governmental agencies and internal company surveys. Industry publications and surveys generally state that the information they contain has been obtained from sources believed to be reliable, but we cannot assure you that this information is accurate or complete. We have not independently verified any of the data from third-party sources nor have we ascertained the underlying economic assumptions relied upon therein. Statements as to our market position are based on the most currently available market data. For market comparison purposes, The Nasdaq Stock Market data in this Quarterly Report on Form 10-Q for IPOs is based on data generated internally by us, which includes best efforts underwritings; therefore, the data may not be comparable to other publicly-available IPO data. Data in this Quarterly Report on Form 10-Q for new listings of equity securities on The Nasdaq Stock Market is based on data generated internally by us, which includes best efforts underwritings, issuers that switched from other listing venues, closed-end funds and ETPs. Data in this Quarterly Report on Form 10-Q for IPOs and new listings of equity securities on the Nasdaq Nordic and Nasdaq Baltic exchanges also is based on data generated internally by us. IPOs and new listings data is presented as of period end. While we are not aware of any misstatements regarding industry data presented herein, our estimates involve risks and uncertainties and are subject to change based on various factors. We refer you to the “Risk Factors” section in this Quarterly Report on Form 10-Q for the quarter ended June 30, 2018, the “Risk Factors” section in the Quarterly Report on Form 10-Q for the quarter ended March 31, 2018 that was filed with the SEC on May 2, 2018, and the “Risk Factors” section in our Annual Report on Form 10-K for the fiscal year ended December 31, 2017 that was filed with the SEC on February 28, 2018.

Forward-Looking Statements

The SEC encourages companies to disclose forward-looking information so that investors can better understand a company’s future prospects and make informed investment decisions. This Quarterly Report on Form 10-Q contains these types of statements. Words such as “may,” “will,” “could,” “should,” “anticipates,” “envisions,” “estimates,” “expects,” “projects,” “intends,” “plans,” “believes” and words or terms of similar substance used in connection with any discussion of future expectations as to industry and regulatory developments or business initiatives and strategies, future operating results or financial performance, and other future developments identify forward-looking statements. These include, among others, statements relating to:

• our strategy, growth forecasts and 2018 outlook;

• the integration of acquired businesses, including accounting decisions relating thereto;

• the scope, nature or impact of acquisitions, divestitures, investments, joint ventures or other transactional activities;

• the effective dates for, and expected benefits of, ongoing initiatives, including transactional activities and other strategic, restructuring, technology, de-leveraging and capital return initiatives;

• our products, order backlog and services;

• the impact of pricing changes;

• tax matters;

• the cost and availability of liquidity and capital; and

• any litigation, or any regulatory or government investigation or action, to which we are or could become a party or which may affect us.

Forward-looking statements involve risks and uncertainties. Factors that could cause actual results to differ materially from those contemplated by the forward-looking statements include, among others, the following:

• our operating results may be lower than expected;

• our ability to successfully integrate acquired businesses or divest sold businesses or assets, including the fact that any integration may be more difficult, time consuming or costly than expected, and we may be unable to realize synergies from business combinations, acquisitions, divestitures or other transactional activities;

• loss of significant trading and clearing volumes or values, fees, market share, listed companies, market data products customers or other customers;

• our ability to keep up with rapid technological advances and adequately address cybersecurity risks;

• economic, political and market conditions and fluctuations, including interest rate and foreign currency risk, inherent in U.S. and international operations;

• the performance and reliability of our technology and technology of third parties on which we rely;

• any significant error in our operational processes;

• our ability to continue to generate cash and manage our indebtedness; and

• adverse changes that may occur in the litigation or regulatory areas, or in the securities markets generally.

Most of these factors are difficult to predict accurately and are generally beyond our control. You should consider the uncertainty and any risk related to forward-looking statements that we make. These risk factors are discussed under the caption “Part II. Item 1A. Risk Factors,” in this Quarterly Report on Form 10-Q for the quarter ended June 30, 2018, our Quarterly Report on Form 10-Q for the quarter ended March 31, 2018 that was filed with the SEC on May 2, 2018, and more fully described in the “Risk Factors,” section in our Annual Report on Form 10-K for the fiscal year ended December 31, 2017 that was filed with the SEC on February 28, 2018. You are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date of this report. You should carefully read this entire Quarterly Report on Form 10-Q, including “Part I. Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations,” and the condensed consolidated financial statements and the related notes. Except as required by the federal securities laws, we undertake no obligation to update any forward-looking statement, release publicly any revisions to any forward-looking statements or report the occurrence of unanticipated events. For any forward-looking statements contained in any document, we claim the protection of the safe harbor for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995.

Nasdaq, Inc.

Notes to Condensed Consolidated Financial Statements (Unaudited)

1. Organization and Nature of Operations

Nasdaq, Inc. is a leading provider of trading, clearing, marketplace technology, regulatory, securities listing, information and public and private company services. Our global offerings are diverse and include trading and clearing across multiple asset classes, trade management services, market data products, financial indexes, capital formation solutions, corporate solutions, and market technology products and services. Our technology powers markets across the globe, supporting equity derivative trading, clearing and settlement, cash equity trading, fixed income trading, trading surveillance and many other functions.

We manage, operate and provide our products and services in four business segments: Market Services, Corporate Services, Information Services and Market Technology.

Market Services

Our Market Services segment includes our Equity Derivative Trading and Clearing, Cash Equity Trading, FICC and Trade Management Services businesses. We operate multiple exchanges and other marketplace facilities across several asset classes, including derivatives, commodities, cash equity, debt, structured products and ETPs. In addition, in some countries where we operate exchanges, we also provide broker services, clearing, settlement and central depository services. Our transaction-based platforms provide market participants with the ability to access, process, display and integrate orders and quotes. The platforms allow the routing and execution of buy and sell orders as well as the reporting of transactions, providing fee-based revenues.

In the U.S., we operate six electronic options exchanges and three cash equity exchanges. The Nasdaq Stock Market, the largest of our cash equities exchanges, is the largest single venue of liquidity for trading U.S.-listed cash equities. We also operate an electronic platform for trading of U.S. Treasuries and NFX, a U.S. based designated contract market which lists cash-settled energy derivatives based on key energy benchmarks including oil, natural gas and U.S. power. In addition, we also operate a Canadian exchange for the trading of Canadian-listed securities.

In Europe, we operate exchanges in Stockholm (Sweden), Copenhagen (Denmark), Helsinki (Finland), and Reykjavik (Iceland), as well as the clearing operations of Nasdaq Clearing, as Nasdaq Nordic. We also operate exchanges in Tallinn (Estonia), Riga (Latvia) and Vilnius (Lithuania) as Nasdaq Baltic. Collectively, Nasdaq Nordic and Nasdaq Baltic offer trading in cash equities, depository receipts, warrants, convertibles, rights, fund units and ETFs, as well as trading and clearing of derivatives and clearing of resale and repurchase agreements.

Nasdaq Commodities is the brand name for Nasdaq’s worldwide suite of commodity-related products and services.

Nasdaq Commodities’ offerings include oil, power, natural gas and carbon emission markets, tanker and dry cargo freight, seafood derivatives, iron ore, electricity certificates and clearing services. These products are listed on two of Nasdaq’s derivatives exchanges, Nasdaq Oslo ASA and NFX.

Through our Trade Management Services business, we provide market participants with a wide variety of alternatives for connecting to and accessing our markets via a number of different protocols used for quoting, order entry, trade reporting, DROP functionality and connectivity to various data feeds. We also provide data center services, including co-location to market participants, whereby firms may lease cabinet space and power to house their own equipment and servers within our data centers. Our broker services operations offer technology and customized securities administration solutions to financial participants in the Nordic market.

Corporate Services

Our Corporate Services segment includes our Corporate Solutions and Listing Services businesses.

Our Corporate Solutions business serves corporate clients, including companies listed on our exchanges and private companies. We help organizations manage the two-way flow of information with their key constituents, including their board members and investors, and with clients and the public through our suite of advanced technology, analytics, and consultative services. In April 2018, we sold our Public Relations Solutions and Digital Media Services businesses. See “2018 Divestiture,” of Note 4, “Divestiture and Acquisitions,” for further discussion. As of June 30, 2018, our Corporate Solutions business includes our investor relations, board & leadership, and governance, risk and compliance products and services.

For segment reporting purposes, we have included in corporate items the revenues and expenses of the Public Relations Solutions and Digital Media Services businesses, which were part of the Corporate Solutions business, within our Corporate Services segment, prior to the date of sale. See Note 18, “Business Segments,” for further discussion.

We have realigned our businesses to better serve the needs of our corporate clients. As a result, beginning in the second quarter of 2018, our BWise corporate enterprise risk management solutions are now offered as part of governance, risk and compliance products and services within our Corporate Solutions business. BWise was previously part of our Market Technology segment.

Our Listing Services business includes our U.S. and European Listing Services businesses. We operate a variety of listing platforms around the world to provide multiple global capital raising solutions for private and public companies. Our main listing markets are The Nasdaq Stock Market and the Nasdaq Nordic and Nasdaq Baltic exchanges. Through Nasdaq First North, our Nordic and Baltic operations also offer alternative marketplaces for smaller companies and growth companies. Our Listing Services business also includes NPM, which provides liquidity solutions for private companies.

6

As of June 30, 2018, there were 3,004 total listings on The Nasdaq Stock Market, including 380 ETPs. The combined market capitalization was approximately $12.5 trillion. In Europe, the Nasdaq Nordic and Nasdaq Baltic exchanges, together with Nasdaq First North, were home to 1,008 listed companies with a combined market capitalization of approximately $1.5 trillion.

Information Services

Beginning in the second quarter of 2018, our Information Services segment was recategorized into the following businesses:

• Market Data;

• Index; and

• Investment Data & Analytics.

Prior to the second quarter, our Information Services segment was comprised of our Data Products and our Index Licensing and Services businesses.

2. Basis of Presentation and Principles of Consolidation

The condensed consolidated financial statements are prepared in accordance with U.S. GAAP and include the accounts of Nasdaq, its wholly-owned subsidiaries and other entities in which Nasdaq has a controlling financial interest. When we do not have a controlling interest in an entity but exercise significant influence over the entity’s operating and financial policies, such investment is accounted for under the equity method of accounting. We recognize our share of earnings or losses of an equity method investee based on our ownership percentage. See “Equity Method Investments,” of Note 7, “Investments,” for further discussion of our equity method investments.

The accompanying condensed consolidated financial statements reflect all adjustments which are, in the opinion of management, necessary for a fair statement of the results for the interim periods presented. These adjustments are of a normal recurring nature. All significant intercompany accounts and transactions have been eliminated in consolidation.

As permitted under U.S. GAAP, certain footnotes or other financial information can be condensed or omitted in the interim condensed consolidated financial statements. The information included in this Quarterly Report on Form 10-Q should be read in conjunction with the consolidated financial statements and accompanying notes included in Nasdaq’s Annual Report on Form 10-K for the fiscal year ended December 31, 2017.

Certain prior year amounts have been reclassified to conform to the current year presentation primarily due to the adoption of ASU 2014-09, “Revenue from Contracts with Customers (Topic 606),” on January 1, 2018. See Note 3, “Significant Accounting Policies Update,” for further discussion.

The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts and the disclosure of contingent amounts in the condensed consolidated financial statements and accompanying notes. Actual results could differ from those estimates.

Subsequent Events

We have evaluated subsequent events through the issuance date of this Quarterly Report on Form 10-Q.

Recent Accounting Pronouncements

Accounting Standard	Description	Effective Date	Effect on the Financial Statements or Other Significant Matters
Income Statement - Reporting Comprehensive Income In February 2018, the FASB issued ASU 2018-02, “Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (Topic 220).”	This ASU provides an election to reclassify tax effects that are stranded in accumulated other comprehensive income as a result of tax reform to retained earnings. An election is also available to reclassify other stranded tax effects that relate to the Tax Cuts and Jobs Act but do not directly relate to the change in the federal rate. Tax effects that are stranded in accumulated other comprehensive income for other reasons (e.g., prior changes in tax law, a change in valuation allowance) may not be reclassified. Previously, the effects of changes in tax rates and laws on deferred tax balances were required to be recorded as a component of tax expense related to continuing operations for the period in which the law was enacted, even if the assets and liabilities related to items of accumulated other comprehensive income. In other words, backward tracing of the income tax effects of items originally recognized through accumulated other comprehensive income was prohibited.	January 1, 2019, with early adoption permitted. We early adopted this standard on January 1, 2018.	As a result of the adoption of this standard, in the first quarter of 2018, we recorded a reclassification of $142 million for stranded tax effects related to the Tax Cuts and Jobs Act from accumulated other comprehensive loss to retained earnings within stockholders’ equity in the Condensed Consolidated Balance Sheets. See Note 17, “Income Taxes,” for further discussion.
Goodwill In January 2017, the FASB issued ASU 2017-04, “Simplifying the Test for Goodwill Impairment.”	This ASU simplifies how an entity is required to test goodwill for impairment and removes the second step of the goodwill impairment test, which required a hypothetical purchase price allocation if the fair value of a reporting unit is less than its carrying amount. Goodwill impairment will now be measured using the difference between the carrying amount and the fair value of the reporting unit and the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. The amendments in this ASU should be applied on a prospective basis.	January 1, 2020, with early adoption permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017.	We do not anticipate a material impact on our consolidated financial statements at the time of adoption of this new standard as the carrying amounts of our reporting units have been less than their corresponding fair values in recent years. Therefore, the second step of the goodwill impairment test was not required. However, changes in future projections, market conditions and other factors may cause a change in the excess of fair value of our reporting units over their corresponding carrying amounts. We do not anticipate early adoption of this standard.
Financial Instruments - Credit Losses In June 2016, the FASB issued ASU 2016-13, “Measurement of Credit Losses on Financial Instruments.”	This ASU changes the impairment model for certain financial instruments. The new model is a forward looking expected loss model and will apply to financial assets subject to credit losses and measured at amortized cost and certain off-balance sheet credit exposures. This includes loans, held-to-maturity debt securities, loan commitments, financial guarantees and net investments in leases, as well as trade receivables. For available-for-sale debt securities with unrealized losses, credit losses will be measured in a manner similar to today, except that the losses will be recognized as allowances rather than reductions in the amortized cost of the securities.	January 1, 2020, with early adoption permitted as of January 1, 2019.	We are currently assessing the impact that this standard will have on our consolidated financial statements. We do not anticipate early adoption of this standard.

Accounting Standard	Description	Effective Date	Effect on the Financial Statements or Other Significant Matters
Leases In February 2016, the FASB issued ASU 2016-02, “Leases.”	Under this ASU, at the commencement date, lessees will be required to recognize a lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis; and a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. This guidance is not applicable for leases with a term of 12 months or less. Recognition, measurement and presentation of expenses will depend on classification as a finance or operating lease. The guidance also requires certain quantitative and qualitative disclosures about leasing arrangements. Lessor accounting is largely unchanged. In transition, lessees and lessors are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach.	January 1, 2019, with early adoption permitted.	See discussion below.

Leases

When adopted, ASU 2016-02 will result in an increase in the assets and liabilities reflected on our consolidated balance sheets. In addition, we will be required to disclose key information about our leases. We are in the process of determining the scope of arrangements that will be subject to this standard, as well as assessing the impact to our business processes, systems and internal controls to support adoption of this new standard. Nasdaq’s current operating lease portfolio is primarily comprised of real estate and data center leases.

We plan to adopt this new standard on January 1, 2019. The guidance is to be applied using a modified retrospective transaction approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. However, in March 2018, the FASB approved an optional transition alternative, which allows for application of the guidance at the effective date, without adjusting the comparative periods presented.

While we continue to assess the effect of adoption of this new standard and the available practical expedients, we expect that most of our operating lease commitments will be subject to the new guidance and will be recognized as right-of-use assets and lease liabilities upon adoption in our consolidated balance sheets. We do not expect the adoption of this new standard to have a material impact on our consolidated statements of income and it will not impact our cash flows.

3. Significant Accounting Policies Update

Our significant accounting policies are detailed in Note 2, “Summary of Significant Accounting Policies,” in our Annual Report on Form 10-K for the year ended December 31, 2017 that was filed with the SEC on February 28, 2018. Significant changes to our accounting policies as a result of adopting Topic 606 and ASU 2016-01, “Recognition and Measurement of Financial Assets and Financial Liabilities,” or ASU 2016-01, are discussed below.

Revenue From Contracts With Customers

On January 1, 2018, we adopted Topic 606 using the full retrospective method. The adoption of Topic 606 impacted the revenue and expense recognition for our Market Technology business and revenue recognition for our Listing Services business. However, the adoption of Topic 606 did not have a material impact on our consolidated financial statements at the time of adoption or in any prior reporting periods. There was

no impact to revenue and expense recognition for our other businesses. Additional disclosures required by Topic 606 are provided below.

Contract Balances

Substantially all of our revenues are considered to be revenues from contracts with customers. The related accounts receivable balances are recorded in our Condensed Consolidated Balance Sheets as receivables which is net of allowance for doubtful accounts of $13 million as of June 30, 2018 and $9 million as of December 31, 2017. The changes in the balance between periods were immaterial. We do not have obligations for warranties, returns or refunds to customers.

For the majority of our contracts with customers, except for our market technology and listings services contracts, our performance obligations are short-term in nature and there is no significant variable consideration.

We do not have significant revenues recognized from

9

performance obligations that were satisfied in prior periods. We have elected not to provide disclosures about transaction price allocated to unsatisfied performance obligations if contract durations are less than one year. For contract durations that are one-year or greater, we do not have a material portion of transaction price allocated to unsatisfied performance obligations that are not included in deferred revenue other than for our market technology contracts which are discussed below under “Market Technology.” Deferred revenue primarily represents our contract liabilities related to our fees for annual and initial listings, market technology, corporate solutions and information services contracts. Deferred revenue is the only significant contract asset or liability impacted by our adoption of Topic 606. See Note 8, “Deferred Revenue,” for our discussion on deferred revenue balances, activity, and expected timing of recognition. See “Revenue Recognition” below for further descriptions of our revenue contracts.

Sales commissions earned by our sales force are considered incremental and recoverable costs of obtaining a contract with a customer. These costs are deferred and amortized on a straight-line basis over the period of benefit that we have determined to be the contract term or estimated service periods. Sales commissions for renewal contracts are deferred and amortized on a straight-line basis over the related contractual renewal period. Amortization expense is included in compensation and benefits expense in the Condensed Consolidated Statements of Income. The balance of deferred costs and related amortization expense are not material to our consolidated financial statements. We elected the practical expedient of recognizing sales commissions as an expense when incurred if contract durations are one year or less. We also have elected the practical expedient of excluding sales taxes from transaction prices.

Certain judgments and estimates were used in the identification and timing of satisfaction of performance obligations and the related allocation of transaction price and are discussed below. We believe that these represent a faithful depiction of the transfer of services to our customers.

Revenue Recognition

Our primary revenue contract classifications are described below. Though we discuss additional revenue details in our “Management's Discussion and Analysis of Financial Condition and Results of Operations,” the categories below best represent those that depict similar economic characteristics of the nature, amount, timing and uncertainty of our revenues and cash flows.

Market Services

Transaction-Based Trading and Clearing

Transaction-based trading and clearing includes equity derivative trading and clearing revenues, cash equity trading revenues and FICC revenues. Nasdaq charges transaction fees for trades executed on our exchanges, as well as on orders that are routed to and executed on other market venues. Nasdaq charges clearing fees for contracts cleared with Nasdaq Clearing.

In the U.S., transaction fees are based on trading volumes for trades executed on our U.S. exchanges and in Europe, transaction fees are based on the volume and value of traded and cleared contracts. In Canada, transaction fees are based on trading volumes for trades executed on our Canadian exchange.

Nasdaq satisfies its performance obligation for trading services upon the execution of a customer trade and clearing services when a contract is cleared, as trading and clearing transactions are substantially complete when they are executed and we have no further obligation to the customer at that time. Transaction-based trading and clearing fees can be variable and are based on trade volume tiered discounts. Transaction revenues, as well as any tiered volume discounts, are calculated and billed monthly in accordance with our published fee schedules. In the U.S., we also pay liquidity payments to customers based on our published fee schedules. We use these payments to improve the liquidity on our markets and therefore recognize those payments as a cost of revenue.

The majority of our FICC trading and clearing customers are charged transaction fees, as discussed above, which are based on the volume and value of traded and cleared contracts. We also enter into annual fixed contracts with customers trading U.S. Treasury securities. The customers are charged an annual fixed fee which is billed per the agreement, on a monthly or quarterly basis. Revenues earned on fixed contracts are recognized over time on a ratable basis over the contract period beginning on the date that our service is made available to the customer since the customer receives and consumes the benefit as Nasdaq provides the service.

For U.S. equity derivative trading, we credit a portion of the per share execution charge to the market participant that provides the liquidity. For U.S. cash equity trading, for Nasdaq and Nasdaq PSX, we credit a portion of the per share execution charge to the market participant that provides the liquidity and for Nasdaq BX, we credit a portion of the per share execution charge to the market participant that takes the liquidity. We record these credits as transaction rebates that are included in transaction-based expense in the Condensed Consolidated Statements of Income. These transaction rebates are paid on a monthly basis and the amounts due are included in accounts payable and accrued expenses in the Condensed Consolidated Balance Sheets.

In the U.S., we pay Section 31 fees to the SEC for supervision and regulation of securities markets. We pass these costs along to our customers through our equity derivative trading and clearing fees and our cash equity trading fees. We collect the fees as a pass-through charge from organizations executing eligible trades on our options exchanges and our cash equity platforms and we recognize these amounts in transaction-based expenses when incurred. Section 31 fees received are included in cash and cash equivalents in the Condensed Consolidated Balance Sheets at the time of receipt and, as required by law, the amount due to the SEC is remitted semiannually and recorded as Section 31fees payable to the SEC in the Condensed Consolidated Balance Sheets until paid. Since the amount recorded as revenues is equal to the amount recorded as

10

transaction-based expenses, there is no impact on our revenues less transaction-based expenses. As we hold the cash received until payment to the SEC, we earn interest income on the related cash balances.

Under our Limitation of Liability Rule and procedures, we may, subject to certain caps, provide compensation for losses directly resulting from the systems’ actual failure to correctly process an order, quote, message or other data into our platform. We do not record a liability for any potential claims that may be submitted under the Limitation of Liability Rule unless they meet the provisions required in accordance with U.S. GAAP. As such, losses arising as a result of the rule are accrued and charged to expense only if the loss is probable and estimable.

Trade Management Services

We provide market participants with a wide variety of alternatives for connecting to and accessing our markets for a fee. We also offer market participants co-location services, whereby firms may lease cabinet space and power to house their own equipment and servers within our data centers. These participants are charged monthly fees for cabinet space, connectivity and support in accordance with our published fee schedules and recognized on a monthly basis when the performance obligation is met. We also earn revenues from annual and monthly exchange membership and registration fees. Revenues for providing access to our markets, co-location services and monthly exchange membership and registration fees are recognized on a monthly basis as the service is provided. Revenues from annual fees for exchange membership and registration fees are recognized ratably over the following 12-month period since the customer receives and consumes the benefit as Nasdaq provides the service. We also offer broker services to financial participants in the Nordic market primarily providing flexible back-office systems, which allow customers to entirely or partly outsource their company’s back-office functions. Revenues from broker services are based on a fixed basic fee for administration or licensing, maintenance and operations, and an incremental fee depending on the number of transactions completed. Broker services revenues are generally billed and recognized monthly.

Corporate Solutions

As of June 30, 2018, corporate solutions revenues primarily include subscription and transaction-based income from our investor relations, board & leadership, and governance, risk and compliance products and services. In April 2018, we completed the sale of our Public Relations Solutions and Digital Media Services businesses. See “2018 Divestiture,” of Note 4, “Divestiture and Acquisitions,” for further discussion. Subscription-based revenues earned are recognized over time on a ratable basis over the contract period beginning on the date that our service is made available to the customer since the customer receives and consumes the benefit as Nasdaq provides the service. Generally, fees are billed quarterly in advance and the contract provides for automatic renewal. As part of the subscription agreements, customers can also be charged usage fees based upon actual usage of the services provided. Revenues from usage fees are recognized at a point in time upon

completion of the service.

Listing Services

Listing services revenues primarily include initial listing fees and annual renewal fees. Under Topic 606, the initial listing fee is allocated to multiple performance obligations including initial and subsequent listing services and corporate solutions services (when a company qualifies to receive these services under the applicable Nasdaq rule), as well as a customer's material right to renew the option to list on our exchanges. In performing this allocation, the standalone selling price of the performance obligations is based on the initial and annual listing fees and the standalone selling price of the corporate solutions services is based on its market value. All listing fees are billed upfront and the identified performance obligations are satisfied over time since the customer receives and consumes the benefit as Nasdaq provides the listing service. Upon adoption of Topic 606, the amount of revenue related to the corporate solutions services performance obligation is recognized ratably over a two-year period, which is based on contract terms, with the remaining revenue recognized ratably over time as customers continue to list on our exchanges, which is estimated to be over a period of six years based on our historical listing experience and projected future listing duration.

In the U.S., annual renewal fees are charged based on the number of outstanding shares of companies listed in the U.S. at the end of the prior year and are recognized ratably over the following 12-month period since the customer receives and consumes the benefit as Nasdaq provides the service. European annual renewal fees, which are received from companies listed on our Nasdaq Nordic and Nasdaq Baltic exchanges and Nasdaq First North, are directly related to the listed companies’ market capitalization on a trailing 12-month basis and are recognized ratably over the following 12-month period since the customer receives and consumes the benefit as Nasdaq provides the service.

Market Data Products

Market data products revenues are earned from U.S. and European proprietary market data products. In the U.S., we also earn revenues from U.S. shared tape plans.

We earn revenues primarily based on the number of data subscribers and distributors of our data. Market data products revenues are subscription-based and are recognized on a monthly basis net of amounts due under revenue sharing arrangements with market participants.

For U.S. tape plans, revenues are collected monthly based on published fee schedules and distributed quarterly to the U.S. exchanges based on a formula required by Regulation NMS that takes into account both trading and quoting activity. Revenues are presented on a net basis as we are acting as an agent in this arrangement.

11

Market Data Products Revenue Sharing

The most significant component of market data products revenues recorded on a net basis is the UTP Plan revenue sharing in the U.S. All indicators of principal versus agent reporting under U.S. GAAP have been considered in analyzing the appropriate presentation of UTP Plan revenue sharing. However, the following are the primary indicators of net reporting:

• We are the administrator for the UTP Plan, in addition to being a participant in the UTP Plan. In our unique role as administrator, we facilitate the collection and dissemination of revenues on behalf of the UTP Plan participants. As a participant, we share in the net distribution of revenues according to the plan on the same terms as all other plan participants.

• The operating committee of the UTP Plan, which is comprised of representatives from each of the participants, including us solely in our capacity as a UTP Plan participant, is responsible for setting the level of fees to be paid by distributors and subscribers and taking action in accordance with the provisions of the UTP Plan, subject to SEC approval.

• Risk of loss on the revenue is shared equally among plan participants according to the UTP Plan.

The exchanges that comprise Nasdaq Nordic and Nasdaq Baltic do not have any market data products revenue sharing agreements.

Index

We develop and license Nasdaq branded indexes, associated derivatives and financial products as part of our Global Index Family. We also provide index data products and custom calculation services for third-party clients. Revenues primarily include license fees from these branded indexes, associated derivatives and financial products in the U.S. and abroad. We primarily have two types of license agreements: transaction-based licenses and asset-based licenses. Transaction-based licenses are generally renewable agreements. Customers are charged based on transaction volume or a minimum contract amount, or both. If a customer is charged based on transaction volume, we recognize revenue when the transaction occurs. If a customer is charged based on a minimum contract amount, we recognize revenue on a pro-rata basis over the licensing term since the customer receives and consumes the benefit as Nasdaq provides the service. Asset-based licenses are also generally renewable agreements. Customers are charged based on a percentage of assets under management for licensed products, per the agreement, on a monthly or quarterly basis. These revenues are recognized over the term of the license agreement since the customer receives and consumes the benefit as Nasdaq provides the service. Revenue from index data subscriptions are recognized on a monthly basis.

Investment Data & Analytics

Investment data & analytics revenues are earned from leading investment content and analytics products. We earn revenues primarily based on the number of content and analytics subscribers and distributors of our content and analytics.

These subscription agreements are generally annual in term, payable in advance, and provide for automatic renewal. Subscription-based revenues are recognized over time on a ratable basis over the contract period beginning on the date that our service is made available to the customer since the customer receives and consumes the benefit as Nasdaq provides the service.

Market Technology

Market Technology provides technology solutions for trading, clearing, settlement, surveillance and information dissemination, as well as risk management solutions. Revenues primarily consist of software, license and support revenues, change request and advisory revenues, and software as a service revenues.

In our Market Technology business, we enter into long-term contracts with customers to develop customized technology solutions, license the right to use software, and provide post-contract support and other services to our customers. We also enter into agreements to modify the system solutions sold by Nasdaq after delivery has occurred. In addition, we enter into subscription agreements which allow customers to connect to our servers to access our software.

Our long-term contracts with customers to develop customized technology solutions, license the right to use software and provide post-contract support and other services to our customers have multiple performance obligations. The performance obligations are generally: 1) software license and installation service and 2) software support. We have determined that the software license and installation service are not distinct as the license and the customized installation service are inputs to produce the combined output, a functional and integrated software system.

For contracts with multiple performance obligations, we allocate the contract transaction price to each performance obligation using our best estimate of the standalone selling price of each distinct good or service in the contract. In instances where standalone selling price is not directly observable, such as when we do not sell the product or service separately, we determine the standalone selling price predominately through an expected cost plus a margin approach.

Contract modifications are routine in the performance of our contracts. Contracts are often modified to account for changes in contract specifications or requirements. In most instances, contract modifications are for goods and services that are not distinct, and, therefore, are accounted for as part of the existing contract.

For our long-term contracts, payments are generally made throughout the contract life and can be dependent on either reaching certain milestones or paid upfront in advance of the

12

service period depending on the stage of the contract. For subscription agreements, contract payment terms can be quarterly, annually or monthly, in advance. For all other contracts, payment terms vary.

We generally recognize revenue over time as our customers simultaneously receive and consume the benefits provided by our performance because our customer controls the asset for which we are creating, our performance does not create an asset with alternative use, and we have a right to payment for performance completed to date. For these services, we recognize revenue over time using costs incurred to date relative to total estimated costs at completion to measure progress toward satisfying our performance obligation. Incurred costs represent work performed, which corresponds with, and thereby depicts, the transfer of control to the customer. Contract costs generally include labor and overhead. For software support and update services, and for subscription agreements which allow customers to connect to our servers to access our software, we generally recognize revenue ratably over the service period beginning on the date our service is made available to the customer since the customer receives and

consumes the benefit consistently over the period as Nasdaq provides the services.

Accounting for our long-term contracts requires judgment relative to assessing risks and their impact on the estimate of revenues and costs. Our estimates are impacted by factors such as the potential for schedule and technical issues, productivity, and the complexity of work performed. When adjustments in estimated total contract costs are required, any changes in the estimated revenues from prior estimates are recognized in the current period for the effect of such change. If estimates of total costs to be incurred on a contract exceed estimates of total revenues, a provision for the entire estimated loss on the contract is recorded in the period in which the loss is determined.

Other Revenues

Other revenues include the revenues from the Public Relations Solutions and Digital Media Services businesses which were sold in April 2018. Prior to the sale date, these revenues were included in our Corporate Solutions business and were primarily transaction-based revenues.

For the six months ended June 30, 2018, approximately 65.0% of Market Services revenues were recognized at a point in time and 35.0% were recognized over time. For the six months ended June 30, 2017, approximately 64.0% of Market Services revenues were recognized at a point in time and 36.0% were recognized over time. Substantially all revenues from the Corporate Services, Information Services and Market Technology segments were recognized over time for both the six months ended June 30, 2018 and 2017.

Equity Securities

On January 1, 2018, we adopted ASU 2016-01 which requires that investments in equity securities (excluding equity method investments) be measured at fair value with changes in fair value recognized in net income. Equity securities are no longer classified as trading or available for sale.

We elected the measurement alternative for equity securities which were historically accounted for under the cost method of accounting. Since these equity securities do not have readily determinable fair values, they are measured at cost, less any impairment, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. We evaluate these

securities for impairment by considering a variety of factors such as the earnings capacity of the investment. If a qualitative assessment indicates that the security is impaired, Nasdaq will estimate the fair value of the security, and if the fair value is less than the carrying amount of the security, recognize an impairment loss in net income equal to the difference between the carrying amount and fair value. There was no impact on our condensed consolidated financial statements as a result of this change.

The guidance for classifying and measuring investments in debt securities is unchanged. Therefore, changes in debt securities classified as trading securities are included in dividend and investment income in the Condensed Consolidated Statements of Income and debt securities classified as available-for-sale

15

investment securities are carried at fair value with unrealized gains and losses, net of tax, reported in accumulated other comprehensive loss within stockholders’ equity in the Condensed Consolidated Balance Sheets. Realized gains and losses on these securities are included in earnings upon disposition of the securities using the specific identification method. In addition, realized losses are recognized when management determines that a decline in value is other than

temporary, which requires judgment regarding the amount and timing of recovery. For financial investments that are classified as available-for-sale securities, we also consider the extent to which cost exceeds fair value, the duration of that difference, management’s judgment about the issuer’s current and prospective financial condition, as well as our intent and ability to hold the security until recovery of the unrealized losses.

4. Divestiture and Acquisitions

We completed the following divestiture in 2018 and acquisitions in 2017. Financial results of each transaction are included in our Condensed Consolidated Statements of Income from the date of each divestiture or acquisition.

2018 Divestiture

In April 2018, we sold our Public Relations Solutions and Digital Media Services businesses which were part of our Corporate Solutions business to West Corporation and recognized a pre-tax gain on the sale of $41 million, net of disposal costs ($19 million after tax). The pretax gain is included in gain on divestiture of businesses, net in the Condensed Consolidated Statements of Income for the three and six months ended June 30, 2018.

As of December 31, 2017, the assets and liabilities of the above businesses were held for sale. See Note 5, “Assets and Liabilities Held For Sale,” for further discussion.

Through a multi-year partnership with West, Nasdaq will continue to provide eligible Nasdaq-listed clients with access to public relations, webcasting and webhosting products and services as part of the terms of the transaction.

As part of the terms of the transaction, we will provide transition services to West, such as technology, finance and facilities related services for a period of time, and the compensation received for such transition services will be reflected as a reduction to the underlying expenses incurred by Nasdaq to provide such transition services.

2017 Acquisitions

	Purchase Consideration		Total Net Liabilities Acquired			Total Net Deferred Tax Liability			Acquired Intangible Assets		Goodwill
	(in millions)
eVestment	$	744	$	(10	)	$	(104	)	$	405	$	453

The amounts in the table above represent the preliminary allocation of purchase price as of June 30, 2018 and are subject to revision during the remainder of the measurement period, a period not to exceed 12 months from the acquisition date. Adjustments to the provisional values, which may include tax and other estimates, during the measurement period will be recorded in the reporting period in which the adjustment amounts are determined. Changes to amounts recorded as assets and liabilities may result in a corresponding adjustment to goodwill.

See “Intangible Assets” below for further discussion of intangible assets acquired in the eVestment acquisition.

Acquisition of eVestment

In October 2017, we acquired eVestment for $705 million. The aggregate cash consideration of $744 million, which is net of cash acquired of $22 million, included $39 million of estimated tax benefits associated with the transaction. We acquired net liabilities, at fair value, totaling $10 million and we recorded a net deferred tax liability of $104 million, which is net of the $39 million in estimated tax benefits associated with the transaction. The deferred tax liability recorded of $143 million relates to differences in the U.S. GAAP and tax basis of our

investment in eVestment. eVestment is part of our Information Services segment.

Nasdaq used cash on hand and issuances of commercial paper to fund this acquisition.

Acquisition of Sybenetix

In September 2017, we acquired Sybenetix for an immaterial amount. Sybenetix is part of our Market Technology segment.

Intangible Assets

The following table presents the details of acquired intangible assets for eVestment at the date of the acquisition. All acquired intangible assets with finite lives are amortized using the straight-line method.

Intangible Assets
($ in millions)
Customer relationships	$	378
Discount rate used	9.3		%
Estimated average useful life	14 years
Trade name	$	13
Discount rate used	9.2		%
Estimated average useful life	8 years
Technology	$	14
Discount rate used	9.2		%
Estimated average useful life	8 years
Total intangible assets	$	405

Customer Relationships

Customer relationships represent the non-contractual and contractual relationships with customers.

Methodology

For our acquisition of eVestment, customer relationships were valued using the income approach, specifically an excess earnings method. The excess earnings method examines the economic returns contributed by the identified tangible and intangible assets of a company, and then isolates the excess return that is attributable to the intangible asset being valued.

Discount Rates

The discount rates used reflect the amount of risk associated with the hypothetical cash flows for the customer relationships relative to the overall business. In developing a discount rate for the customer relationships, we estimated a weighted-average cost of capital for the overall business and we employed this rate when discounting the cash flows. The resulting discounted cash flows were then tax-effected at the applicable statutory rate.

For our acquisition of eVestment, a discounted tax amortization benefit was added to the fair value of the assets under the assumption that the customer relationships would be amortized for tax purposes over a period of 15 years.

Estimated Useful Life

We estimate the useful life based on the historical behavior of the customers and a parallel analysis of the customers using the excess earnings method.

Trade Name

As part of our acquisition of eVestment, we acquired a trade name. This trade name is recognized in the industry and carries a reputation for quality. As such, the reputation and positive recognition embodied in this trade name is a valuable asset to Nasdaq.

Methodology

The eVestment trade name was valued using the income approach, specifically the relief-from-royalty method, or RFRM. The RFRM is used to estimate the cost savings that accrue to the owner of an intangible asset who would otherwise have to pay royalties or license fees on revenues earned through the use of the asset. The royalty rate is applied to the projected revenue over the expected remaining life of the intangible asset to estimate royalty savings. The net after-tax royalty savings are calculated for each year in the remaining economic life of the trade name and discounted to present value.

The discount rate used reflects the amount of risk associated with the hypothetical cash flows for the trade name relative to the overall business as discussed above in “Customer Relationships.”

We have estimated the useful life of the eVestment trade name to be 8 years.

Technology

As part of our acquisition of eVestment, we acquired developed technology.

Methodology

The developed technology was valued using the income approach, specifically the RFRM as discussed above in “Trade Names.”

Discount rate

The discount rate used reflects the amount of risk associated with the hypothetical cash flows for the developed technology relative to the overall business as discussed above in “Customer Relationships.”

Estimated Useful Life

We have estimated the useful life of the eVestment technology to be 8 years.

Pro Forma Results and Acquisition-related Costs

The condensed consolidated financial statements for the three and six months ended June 30, 2018 and 2017 include the financial results of the above 2017 acquisitions from the date of each acquisition. Pro forma financial results have not been presented since these acquisitions both individually and in the aggregate were not material to our financial results.

Acquisition-related costs for the transactions described above were expensed as incurred and are included in merger and strategic initiatives expense in the Condensed Consolidated Statements of Income.

5. Assets and Liabilities Held For Sale

In September 2017, we commenced a process to evaluate strategic alternatives for our Public Relations Solutions and Digital Media Services businesses within our Corporate Solutions business as part of our strategic refinement and subsequently committed to a plan to divest these businesses.

17

The Corporate Solutions business is part of our Corporate Services segment. The Public Relations Solutions and Digital Media Services businesses included the following products and services:

• Nasdaq GlobeNewswire;

• Nasdaq Influencers;

• Nasdaq Media Intelligence;

• Nasdaq IR Websites and Newsrooms; and

• Nasdaq Webcasts.

We determined that we met all of the criteria to classify the assets and liabilities of these businesses as held for sale. The disposal of these businesses did not represent a strategic shift that would have a major effect on our operations and financial results and were, therefore, not classified as discontinued operations. As a result of this classification, the assets and liabilities of these businesses were separately presented within the Condensed Consolidated Balance Sheets as held for sale and were recorded at the lower of their carrying amount or fair value less costs to sell.

In January 2018, we entered into a definitive agreement to sell the above businesses for $335 million, subject to post-closing adjustments and, in April 2018, we completed the sale and recognized a pre-tax gain on the sale of $41 million, net of disposal costs ($19 million after tax). See “2018 Divestiture,” of Note 4, “Divestiture and Acquisitions,” for further discussion.

Based on the sales price in the agreement, no impairment charge was recorded at the time of the sale as the carrying amount of the net assets was less than the sales price in the agreement less costs to sell.

The carrying amounts of the major classes of assets and liabilities that were classified as held for sale at December 31, 2017 in the Condensed Consolidated Balance Sheets were as follows:

	December 31, 2017
	(in millions)
Receivables, net	$	27
Property and equipment, net	21
Goodwill (1)	202
Intangible assets, net(2)	38
Other assets	9
Total assets held for sale	$	297
Deferred tax liabilities	$	16
Other current liabilities	29
Total liabilities held for sale	$	45

____________

⁽¹⁾  The assignment of goodwill was based on the relative fair value of the disposal group and the portion of the remaining reporting unit.

⁽²⁾ Primarily represents customer relationships.

6. Goodwill andAcquiredIntangible Assets

Goodwill

The following table presents the changes in goodwill by business segment during the six months ended June 30, 2018:

	Market Services			Corporate Services			Information Services			Market Technology			Total
	(in millions)
Balance at December 31, 2017	$	3,546		$	490		$	2,362		$	188		$	6,586

Balance at June 30, 2018	$	3,425		$	504		$	2,275		$	151		$	6,355

____________

⁽¹⁾Concurrent with the realignment of our BWise corporate enterprise risk management solutions from our Market Technology segment to our Corporate Services segment, goodwill was reassigned to the Corporate Services segment using a relative fair value approach.

As of June 30, 2018, the amount of goodwill that is expected to be deductible for tax purposes in future periods is $763 million.

Goodwill represents the excess of purchase price over the value assigned to the net assets, including identifiable intangible assets, of a business acquired. Goodwill is allocated to our reporting units based on the assignment of the fair values of each reporting unit of the acquired company. We test goodwill for impairment at the reporting unit level annually, or in interim

periods if certain events occur indicating that the carrying amount may be impaired, such as changes in the business climate, poor indicators of operating performance or the sale or disposition of a significant portion of a reporting unit. There was no impairment of goodwill for the six months ended June 30, 2018 and 2017; however, events such as extended economic weakness or unexpected significant declines in operating results of a reporting unit may result in goodwill impairment charges in the future.

Amortization expense for acquired finite-lived intangible assets was $28 million for the three months ended June 30, 2018, $22 million for the three months ended June 30, 2017, $56 million for the six months ended June 30, 2018, and $45 million for the six months ended June 30, 2017. Amortization expense increased in 2018 primarily due to additional amortization expense associated with acquired intangible assets in 2017. These amounts are included in depreciation and amortization expense in the Condensed Consolidated Statements of Income.

The estimated future amortization expense (excluding the impact of foreign currency translation adjustments of $84 million as of June 30, 2018) of acquired finite-lived intangible assets as of June 30, 2018 is as follows:

	(in millions)
2018(1)	$	56
2019	99
2020	98
2021	97
2022	94
2023 and thereafter	736
Total	$	1,180

____________

⁽¹⁾Represents the estimated amortization to be recognized for

the remaining six months of 2018.

In April 2018, in connection with the sale of the Public Relations Solutions and Digital Media Services businesses, we recorded a $2 million pre-tax, non-cash write-off related to an indefinite-lived intangible asset trade name.

Equity securities	$	79	$	152

Financial Investments, at Fair Value

Trading Securities

Trading securities, which are included in financial investments, at fair value in the Condensed Consolidated Balance Sheets, are primarily comprised of highly rated European government

19

debt securities, of which $153 million as of June 30, 2018 and $160 million as of December 31, 2017, are assets utilized to meet regulatory capital requirements, primarily for our clearing operations at Nasdaq Clearing.

Available-for-Sale Investment Securities

As of June 30, 2018 and December 31, 2017, available-for-sale investment securities, which are included in financial investments, at fair value in the Condensed Consolidated Balance Sheets, are primarily comprised of commercial paper debt securities. As of June 30, 2018 and December 31, 2017, the cumulative unrealized gains and losses on these securities were immaterial.

Equity Method Investments

As of June 30, 2018 and December 31, 2017, our equity method investments primarily included equity interests in OCC and EuroCCP N.V.

The carrying amounts of our equity method investments are included in other non-current assets in the Condensed Consolidated Balance Sheets.

Net income recognized from our equity interest in the earnings and losses of these equity method investments was $5 million for the three months ended June 30, 2018, $2 million for the three months ended June 30, 2017, $7 million for the six months ended June 30, 2018, and $6 million for the six months ended June 30, 2017.

Capital Contribution to OCC

In March 2015, OCC implemented a capital plan under which the options exchanges that are OCC’s stockholders contributed $150 million of new equity capital to OCC, committed to make future replenishment capital contributions under certain circumstances, and received commitments regarding future dividend payments and related matters. See “Other Commitments,” of Note 16, “Commitments, Contingencies and Guarantees,” for further discussion of our commitment to make future replenishment capital contributions. Nasdaq and ISE each contributed $30 million of new equity capital under the OCC capital plan. OCC adopted specific policies with respect to fees, customer refunds and stockholder dividends, which

envision an annual dividend equal to the portion of OCC’s after-tax income that exceeds OCC’s capital requirements after payment of refunds to OCC’s clearing members (such refunds are generally 50% of the portion of OCC’s pre-tax income that exceeds OCC’s capital requirements). In February 2016, the SEC approved the OCC capital plan and certain industry participants appealed that approval in the Federal Court Of Appeals. The Court of Appeals denied a requested stay, permitting OCC to pay a dividend which Nasdaq received in February 2016. In August 2017, the Court of Appeals remanded the case to the SEC for further examination of the record and an independent assessment by the SEC of the evidence OCC submitted. The Court directed that the SEC approval of the OCC capital plan remain in place during the SEC’s examination unless the SEC determined not to preserve it. The SEC has allowed OCC to preserve the capital plan, and in September 2017, OCC disbursed an annual dividend. Nasdaq, as the owner of two shares, received $10 million. There has been no final ruling by the SEC at this time, and there is no deadline for the SEC to issue its ruling.

Equity Securities 

The carrying amounts of our equity securities are included in other non-current assets in the Condensed Consolidated Balance Sheets. As of June 30, 2018, our equity securities primarily represent our 5% ownership interest in LCH.Clearnet Group Limited. As of December 31, 2017, our equity securities primarily represented our 5% ownership in Borsa Istanbul and our 5% ownership interest in LCH.Clearnet Group Limited. For the six months ended June 30, 2018, no impairment charges were recorded on our equity securities and there were no upward or downward adjustments recorded.

The Borsa Istanbul shares, which were issued to us in the first quarter of 2014, were part of the consideration received under a market technology agreement. This investment had a carrying amount of $75 million which was guaranteed to us via a put option negotiated as part of the market technology agreement. During the second quarter of 2018, we exercised theput option and we expect to receive cash consideration in installments through 2022.

8. Deferred Revenue

Deferred revenue represents consideration received that is yet to be recognized as revenue. The changes in our deferred revenue during the six months ended June 30, 2018 are reflected in the following table: 

	Initial Listing Revenues			Annual Listings Revenues			Market Technology Revenues			Corporate Solutions and Other  Revenues(2)			Information Services Revenues			Other(3)			Total
	(in millions)

____________

⁽¹⁾Concurrent with the realignment of our BWise corporate enterprise risk management solutions from our Market Technology segment to our Corporate Services segment, deferred revenue was reassigned to the Corporate Services segment.

⁽²⁾Other revenues include the revenues from the Public Relations Solutions and Digital Media Services businesses through the date of sale (April 2018). See “2018 Divestiture,” of Note 4, “Divestiture and Acquisitions,” to the condensed consolidated financial statements for further discussion.

⁽³⁾ Other primarily includes revenues from listing of additional shares fees which are included in our Listing Services business.

On January 1, 2018, we adopted Topic 606. As a result, a portion of revenues that were previously deferred were recognized either in prior period revenues, through restatement, or as an adjustment to retained earnings upon adoption of the new standard. See “Revenue From Contracts With Customers,” of Note 3, “Significant Accounting Policies Update,” for a description of our initial listing, annual listing, market

technology, corporate solutions, and information services revenues and the revenue recognition policy for each of these revenue streams.

* * * * * *

As of June 30, 2018, we estimate that our deferred revenue will be recognized in the following years:

	Initial Listing Revenues		Annual Listings Revenues		Market Technology Revenues		Corporate Solutions Revenues		Information Services Revenues		Other(2)		Total
	(in millions)

____________

⁽¹⁾Represents deferred revenue that is anticipated to be recognized over the remaining six months of 2018.

⁽²⁾ Other primarily includes revenues from listing of additional shares fees which are included in our Listing Services business.

The timing of recognition of our deferred market technology revenues is primarily dependent upon the completion of customization and any significant modifications made pursuant to existing market technology contracts. As such, as it relates to market technology revenues, the timing represents our best estimate.

9. Debt Obligations

The following table presents the changes in the carrying amount of our debt obligations during the six months ended June 30, 2018:

	December 31, 2017		Additions		Payments, Accretion and Other			June 30, 2018
Short-term debt:	(in millions)

____________

⁽¹⁾Balance was reclassified to short-term debt as of March 31, 2018.

Commercial Paper Program

Our U.S. dollar commercial paper program is supported by our 2017 Credit Facility which provides liquidity support for the repayment of commercial paper issued through the commercial paper program. See “2017 Credit Facility” below for further discussion of our 2017 Credit Facility. The effective interest rate of commercial paper issuances fluctuate as short term interest rates and demand fluctuate. The fluctuation of these rates due to market conditions may impact our interest expense.

As of June 30, 2018, commercial paper notes in the table above reflect the aggregate principal amount, less the unamortized discount which is being accreted through interest expense over the life of the applicable notes. The original maturities of these notes range from 10 days to 62 days and the weighted-average maturity is 28 days. The weighted-average effective interest rate is 2.46% per annum.

Senior Unsecured Notes

Our senior unsecured notes were all issued at a discount. As a result of the discount, the proceeds received from each issuance were less than the aggregate principal amount. As of June 30, 2018, the amounts in the table above reflect the aggregate principal amount, less the unamortized debt discount and the unamortized debt issuance costs which are being accreted through interest expense over the life of the applicable notes. Our senior unsecured notes are general unsecured obligations of ours and rank equally with all of our existing and future unsubordinated obligations and they are not guaranteed by any

of our subsidiaries. The senior unsecured notes were issued under indentures that, among other things, limit our ability to consolidate, merge or sell all or substantially all of our assets, create liens, and enter into sale and leaseback transactions.

With the exception of the 2020 Notes, upon a change of control triggering event (as defined in the various note indentures), the terms require us to repurchase all or part of each holder’s notes for cash equal to 101% of the aggregate principal amount purchased plus accrued and unpaid interest, if any.

Senior Unsecured Floating Rate Notes

In September 2017, Nasdaq issued the 2019 Notes. The 2019 Notes pay interest quarterly in arrears at a rate equal to the three-month U.S. dollar LIBOR as determined at the beginning of each quarterly period plus 0.39% per annum until March 22, 2019.

5.55% Senior Unsecured Notes

In January 2010, Nasdaq issued the 2020 Notes. The 2020 Notes pay interest semiannually at a rate of 5.55% per annum until January 15, 2020.

3.875% Senior Unsecured Notes

In June 2013, Nasdaq issued the 2021 Notes. The 2021 Notes pay interest annually at a rate of 3.875% per annum until June 7, 2021 and such rate may vary with Nasdaq’s debt rating up to a rate not to exceed 5.875%.

21

The 2021 Notes have been designated as a hedge of our net investment in certain foreign subsidiaries to mitigate the foreign exchange risk associated with certain investments in these subsidiaries. The decrease in the carrying amount of $18 million noted in the “Payments, Accretion and Other” column in the table above primarily reflects the translation of the 2021 Notes into U.S. dollars and is recorded in accumulated other comprehensive loss within stockholders’ equity in the Condensed Consolidated Balance Sheets as of June 30, 2018.

4.25% Senior Unsecured Notes

In May 2014, Nasdaq issued the 2024 Notes. The 2024 Notes pay interest semiannually at a rate of 4.25% per annum until June 1, 2024 and such rate may vary with Nasdaq’s debt rating up to a rate not to exceed 6.25%.

1.75% Senior Unsecured Notes

In May 2016, Nasdaq issued the 2023 Notes. The 2023 Notes pay interest annually at a rate of 1.75% per annum until May 19, 2023 and such rate may vary with Nasdaq’s debt rating up to a rate not to exceed 3.75%.

The 2023 Notes have been designated as a hedge of our net investment in certain foreign subsidiaries to mitigate the foreign exchange rate risk associated with certain investments in these subsidiaries. The decrease in the carrying amount of $18 million noted in the “Payments, Accretion and Other” column in the table above reflects the translation of the 2023 Notes into U.S. dollars and is recorded in accumulated other comprehensive loss within stockholders’ equity in the Condensed Consolidated Balance Sheets as of June 30, 2018.

3.85% Senior Unsecured Notes

In June 2016, Nasdaq issued the 2026 Notes. The 2026 Notes pay interest semiannually at a rate of 3.85% per annum until June 30, 2026 and such rate may vary with Nasdaq’s debt rating up to a rate not to exceed 5.85%.

Credit Facilities

As of June 30, 2018, the amounts in the table above reflect the aggregate principal amount, less the unamortized debt issuance costs which are being accreted through interest expense over the life of the applicable credit facility. Nasdaq is permitted to repay borrowings under our credit facilities at any time in whole or in part, without penalty.

Our credit facilities contain financial and operating covenants. Financial covenants include a minimum interest expense coverage ratio and a maximum leverage ratio. Operating covenants include, among other things, limitations on Nasdaq’s ability to incur additional indebtedness, grant liens on assets, dispose of assets and pay dividends. Our credit facilities allow us to pay cash dividends on our common stock. The facilities also contain customary affirmative covenants, including access to financial statements, notice of defaults and certain other material events, maintenance of properties and insurance, and events of default, including cross-defaults to our material indebtedness.

2017 Credit Facility

In April 2017, Nasdaq entered into the 2017 Credit Facility. The 2017 Credit Facility consists of a $1 billionfive-year revolving credit facility (with sublimits for non-dollar borrowings, swingline borrowings and letters of credit), which replaced a former credit facility. Nasdaq intends to use funds available under the 2017 Credit Facility for general corporate purposes and to provide liquidity support for the repayment of commercial paper issued through the commercial paper program.

As of June 30, 2018, no amounts were outstanding on the 2017 Credit Facility. The $4 million credit balance represents unamortized debt issuance costs. Of the $1 billion that is available for borrowing, $271 million provides liquidity support for the commercial paper program and for a letter of credit. As such, as of June 30, 2018, the total remaining amount available under the 2017 Credit Facility was $729 million. See “Commercial Paper Program” above for further discussion of our commercial paper program.

Under our 2017 Credit Facility, borrowings under the revolving credit facility and swingline borrowings bear interest on the principal amount outstanding at a variable interest rate based on either the LIBOR or the base rate (as defined in the credit agreement) (or other applicable rate with respect to non-dollar borrowings), plus an applicable margin that varies with Nasdaq’s debt rating.

The 2017 Credit Facility includes an option for Nasdaq to increase the available aggregate amount by up to $500 million, subject to the consent of the lenders funding the increase and certain other conditions.

2016 Credit Facility

In March 2016, Nasdaq entered into the 2016 Credit Facility. Under our 2016 Credit Facility, borrowings bear interest on the principal amount outstanding at a variable interest rate based on either the LIBOR or the base rate (or other applicable rate with respect to non-dollar borrowings), plus an applicable margin that varies with Nasdaq’s debt rating.

As of June 30, 2018, the amount outstanding of $100 million is due upon maturity at November 25, 2019.

Other Credit Facilities

We also have credit facilities related to our Nasdaq Clearing operations in order to provide further liquidity. Credit facilities, which are available in multiple currencies, totaled $218 million as of June 30, 2018 and $187 million as of December 31, 2017 in available liquidity, none of which was utilized.

Debt Covenants

As of June 30, 2018, we were in compliance with the covenants of all of our debt obligations.

10. RetirementPlans

Defined Contribution Savings Plan

We sponsor a 401(k) Plan for U.S. employees. Employees are immediately eligible to make contributions to the plan and are also eligible for an employer contribution match at an amount equal to 100.0% of the first 6.0% of eligible employee contributions. Savings plan expense included in compensation and benefits expense in the Condensed Consolidated Statements of Income was $3 million for both the three months ended June 30, 2018 and 2017 and $7 million for both the six months ended June 30, 2018 and 2017.

Pension and Supplemental Executive Retirement Plans

We maintain non-contributory, defined-benefit pension plans, non-qualified SERPs for certain senior executives and other post-retirement benefit plans for eligible employees in the U.S., collectively referred to as the Nasdaq Benefit Plans. Our pension plans and SERPs are frozen. Future service and salary for all participants do not count toward an accrual of benefits under the pension plans and SERPs. Most employees outside the U.S. are covered by local retirement plans or by applicable social laws. Benefits under social laws are generally expensed in the periods in which the costs are incurred. The total expense for these plans is included in compensation and benefits expense in the Condensed Consolidated Statements of Income and was $5 million for the three months June 30, 2018, $4 million for the three months ended June 30, 2017, $11 million for the six months June 30, 2018, and $8 million for the six months ended June 30, 2017.

11. Share-Based Compensation

We have a share-based compensation program that provides our board of directors broad discretion in creating employee equity incentives. Share-based awards granted under this program include stock options, restricted stock (consisting of restricted stock units), and PSUs. For accounting purposes, we consider PSUs to be a form of restricted stock.

Summary of Share-Based Compensation Expense

The following table shows the total share-based compensation expense resulting from equity awards and the 15.0% discount for the ESPP for the three and six months ended June 30, 2018 and 2017 in the Condensed Consolidated Statements of Income:

	Three Months Ended June 30,						Six Months Ended June 30,
	2018			2017			2018			2017
	(in millions)
Share-based compensation expense before income taxes	$	18		$	19		$	33		$	34
Income tax benefit	(5		)	(8		)	(9		)	(14		)
Share-based compensation expense after income taxes	$	13		$	11		$	24		$	20

Common Shares Available Under Our Equity Plan

As of June 30, 2018, we had approximately 10.9 million shares of common stock authorized for future issuance under our Equity Plan.

Restricted Stock

We grant restricted stock to most active employees. The grant date fair value of restricted stock awards is based on the closing price at the date of grant less the present value of future cash dividends. Restricted stock awards granted generally vest 25.0% on the second anniversary of the grant date, 25.0% on the third anniversary of the grant date, and 50.0% on the fourth anniversary of the grant date. We generally recognize compensation expense for restricted stock awards on a straight-line basis over the requisite service period of the award, taking into account an estimated forfeiture rate.

Summary of Restricted Stock Activity

The following table summarizes our restricted stock activity for the six months ended June 30, 2018:

	Restricted Stock
	Number of Awards		Weighted-Average Grant Date Fair Value
Unvested balances at January 1, 2018	1,988,500		$	57.34
Granted	484,750		$	81.69
Vested	(646,994	)	$	46.87
Forfeited	(191,365	)	$	62.09
Unvested balances at June 30, 2018	1,634,891		$	68.15

As of June 30, 2018, $64 million of total unrecognized compensation cost related to restricted stock is expected to be recognized over a weighted-average period of 1.9 years.

PSUs

The grant date fair value of PSUs is based on the closing price at the date of grant less the present value of future cash dividends. PSUs are based on performance measures that impact the amount of shares that each recipient will receive upon vesting. We report the target number of PSUs granted, unless we have determined that it is more likely than not, based on the actual achievement of performance measures, that an employee will receive a different amount of shares underlying the PSUs, in which case we report the amount of shares the employee is likely to receive. We have two performance-based long-term PSU programs for certain officers, a one-year performance-based program and a three-year cumulative performance-based program that focuses on TSR.

One-Year PSU Program

Under the one-year performance-based program, an employee may receive from 0.0% to 150.0% of the target amount granted, depending on the achievement of performance measures. These awards vest ratably on an annual basis over a three-year period

23

commencing with the end of the one-year performance period. Compensation cost is recognized over the performance period and the three-year vesting period, taking into account an estimated forfeiture rate.

During 2017, certain grants of PSUs with a one-year performance period exceeded the applicable performance parameters. As a result, an additional 14,497 units above target were considered granted in the first quarter of 2018 and are included in the below table.

Three-Year PSU Program

Under the three-year performance-based program, each individual receives PSUs with a three-year cumulative performance period that vest at the end of the performance period. Compensation cost is recognized over the three-year vesting period. Performance will be determined by comparing Nasdaq’s TSR to two peer groups, each weighted 50.0%. The first peer group consists of exchange companies, and the second peer group consists of all companies in the S&P 500. Nasdaq’s relative performance ranking against each of these groups will determine the final number of shares delivered to each individual under the program. The payout under this program will be between 0.0% and 200.0% of the number of PSUs granted and will be determined by Nasdaq’s overall performance against both peer groups. However, if Nasdaq’s TSR is negative for the three-year performance period, regardless of TSR ranking, the payout will not exceed 100.0% of the number of PSUs granted. We estimate the fair value of PSUs granted under the three-year PSU program using the Monte Carlo simulation model, as these awards contain a market condition.

Certain grants of PSUs that were issued in 2015 with a three-year performance period exceeded the applicable performance parameters. As a result, an additional 237,876 units above target were considered granted in the first quarter of 2018 and are included in the below table.

The following weighted-average assumptions were used to determine the weighted-average fair values of the PSU awards granted under the three-year PSU program for the six months ended June 30, 2018 and 2017:

	Six Months Ended June 30,
	2018		2017
Weighted-average risk free interest rate(1)	2.36	%	1.44	%
Expected volatility(2)	18.7	%	19.2	%
Weighted-average grant date share price	$86.24		$69.45
Weighted-average fair value at grant date	$116.86		$81.57

____________

⁽¹⁾  The risk-free interest rate for periods within the expected life of the award is based on the U.S. Treasury yield curve in effect at the time of grant.

⁽²⁾  We use historic volatility for PSU awards issued under the three-year PSU program, as implied volatility data could not be obtained for all the companies in the peer groups used for relative performance measurement within the program.

In addition, the annual dividend assumption utilized in the Monte Carlo simulation model is based on Nasdaq’s dividend yield at the date of grant.

Summary of PSU Activity

The following table summarizes our PSU activity for the six months ended June 30, 2018:

	PSUs
	One-Year Program				Three-Year Program
	Number of Awards		Weighted-Average Grant Date Fair Value		Number of Awards		Weighted-Average Grant Date Fair Value
Unvested balances at January 1, 2018	333,004		$	61.39	1,009,958		$	78.18
Granted	131,185		$	80.29	484,075		$	90.92
Vested	(6,702	)	$	49.40	(655,204	)	$	64.08
Forfeited	(22,037	)	$	60.69	—		$	—
Unvested balances at June 30, 2018	435,450		$	67.30	838,829		$	96.55

As of June 30, 2018, $13 million of total unrecognized compensation cost related to the one-year PSU program is expected to be recognized over a weighted-average period of 1.5 years. For the three-year PSU program, $40 million of total unrecognized compensation cost is expected to be recognized over a weighted-average period of 1.6 years.

Stock Options

The fair value of stock options is estimated using the Black-Scholes option-pricing model. Each grant has a 10-year life. In

January 2017, our CEO received 268,817 performance-based

non-qualified stock options which will vest annually over a three-year period, with each vesting contingent upon the achievement of annual performance parameters. On January 30, 2018, Nasdaq's management compensation committee and board of directors determined that the performance goal for 2017 was met, resulting in the settlement of the first one-third of the grant. There were no stock option awards granted during the six months ended June 30, 2018.

Summary of Stock Option Activity

A summary of stock option activity for the six months ended June 30, 2018 is as follows:

	Number of Stock Options		Weighted-Average Exercise Price		Weighted-Average Remaining Contractual Term (in years)	Aggregate Intrinsic Value (in millions)
Outstanding at January 1, 2018	571,380		$	43.84	5.40	$	19
Exercised	(88,000	)	24.51
Forfeited	(954	)	34.53
Outstanding at June 30, 2018	482,426		$	47.38	5.61	$	21
Exercisable at June 30, 2018	303,214		$	35.98	3.96	$	17

We received net cash proceeds of $1 million from the exercise of 53,805 stock options for the three months ended June 30, 2018 and received net cash proceeds of $2 million from the exercise of 88,000 stock options for the six months ended June 30, 2018. We received net cash proceeds of $21 million from the exercise of 993,745 stock options for the three months ended June 30, 2017 and received net cash proceeds of $22 million from the exercise of 1,034,161 stock options for the six months ended June 30, 2017.

The aggregate intrinsic value in the above table represents the total pre-tax intrinsic value (i.e., the difference between our closing stock price on June 29, 2018 of $91.27 and the exercise price, times the number of shares) based on stock options with an exercise price less than Nasdaq’s closing price of $91.27 as of June 29, 2018, which would have been received by the option holders had the option holders exercised their stock options on that date. This amount can change based on the fair market value of our common stock. The total number of in-the-money stock options exercisable as of June 30, 2018 was 0.3 million and the weighted-average exercise price was $35.98. As of June 30, 2017, 0.4 million outstanding stock options were exercisable and the weighted-average exercise price was $23.98. 

The total pre-tax intrinsic value of stock options exercised was $4 million for the three months ended June 30, 2018, $49 million for the three months ended June 30, 2017, $6 million for the six months ended June 30, 2018, and $51 million for the six months ended June 30, 2017. 

ESPP

We have an ESPP under which approximately 2.0 million shares of our common stock have been reserved for future issuance as of June 30, 2018. Under our ESPP, employees may purchase shares having a value not exceeding 10.0% of their annual compensation, subject to applicable annual Internal Revenue Service limitations. We record compensation expense related to the 15.0% discount that is given to our employees which totaled $1 million for both the three months ended June 30, 2018 and 2017 and $2 million for both the six months ended June 30, 2018 and 2017.

12.NasdaqStockholders’ Equity

Common Stock

As of June 30, 2018, 300,000,000 shares of our common stock were authorized, 169,968,175 shares were issued and 164,503,404 shares were outstanding. The holders of common stock are entitled to one vote per share, except that our certificate of incorporation limits the ability of any person to vote in excess of 5.0% of the then-outstanding shares of Nasdaq common stock.

Common Stock in Treasury, at Cost

We account for the purchase of treasury stock under the cost method with the shares of stock repurchased reflected as a reduction to Nasdaq stockholders’ equity and included in common stock in treasury, at cost in the Condensed Consolidated Balance Sheets. Shares repurchased under our share repurchase program are currently retired and canceled. When treasury shares are reissued, they are recorded at the average cost of the treasury shares acquired. We held 5,464,771 shares of common stock in treasury as of June 30, 2018 and 4,932,402 shares as of December 31, 2017, most of which are related to shares of our common stock repurchased for the settlement of employee tax withholding obligations arising from the vesting of restricted stock.

Share Repurchase Program

In January 2018, our board of directors authorized an additional $500 million for the share repurchase program bringing the total capacity to $726 million.

These purchases may be made from time to time at prevailing market prices in open market purchases, privately-negotiated transactions, block purchase techniques or otherwise, as determined by our management. The purchases are primarily funded from existing cash balances. The share repurchase program may be suspended, modified or discontinued at any time. The share repurchase program has no defined expiration date.

25

The following table summarizes our share repurchase activity:

	Six Months Ended June 30,
	2018		2017
Number of shares of common stock repurchased	3,929,520		2,215,755
Average price paid per share	$	86.58	$	70.64
Total purchase price (in millions)	$	340	$	156

As discussed above in “Common Stock in Treasury, at Cost,” shares repurchased under our share repurchase program are currently retired and cancelled. As of June 30, 2018, the remaining amount authorized for share repurchases under the program was $386 million.

Other Repurchases of Common Stock

During the first six months of 2018, we repurchased 532,369 shares of our common stock in settlement of employee tax withholding obligations arising from the vesting of restricted stock.

Preferred Stock

Our certificate of incorporation authorizes the issuance of 30,000,000 shares of preferred stock, par value $0.01 per share, issuable from time to time in one or more series. As of June 30, 2018 and December 31, 2017, no shares of preferred stock were issued or outstanding.

Cash Dividends on Common Stock

During the six months ended June 30, 2018, our board of directors declared the following cash dividends:

Declaration Date	Dividend Per Common Share		Record Date	Total Amount Paid		Payment Date
				(in millions)
January 30, 2018	$	0.38	March 16, 2018	$	63	March 30, 2018
March 26, 2018	0.44		June 15, 2018	73		June 29, 2018
				$	136

The total amount paid of $136 million was recorded in retained earnings in the Condensed Consolidated Balance Sheets at June 30, 2018.

In July 2018, the board of directors declared a regular quarterly cash dividend of $0.44 per share on our outstanding common stock. The dividend is payable on September 28, 2018 to shareholders of record at the close of business on September 14, 2018. The estimated amount of this dividend is $72 million. In March 2018, the board of directors declared a regular quarterly cash dividend of $0.44 per share on our outstanding common stock which reflects a 16.0% increase from our prior quarterly cash dividend of $0.38. Future declarations of quarterly dividends and the establishment of future record and payment dates are subject to approval by the board of directors.

Our board of directors maintains a dividend policy with the intention to provide stockholders with regular and growing dividends over the long term as earnings and cash flow grow.

Stock options to purchase 482,426 shares of common stock and 2,909,170 shares of restricted stock and PSUs were outstanding as of June 30, 2018. For the three months ended June 30, 2018, we included all of the outstanding stock options and 2,651,118 shares of restricted stock and PSUs in the computation of diluted earnings per share, on a weighted-average basis, as their inclusion was dilutive. For the six months ended June 30, 2018, we included all of the outstanding stock options and 2,371,680 shares of restricted stock and PSUs in the computation of diluted earnings per share, on a weighted-average basis, as their inclusion was dilutive. The remaining stock options, shares of restricted stock and PSUs are antidilutive, and as such, they were properly excluded.

Stock options to purchase 640,449 shares of common stock and 4,108,802 shares of restricted stock and PSUs were outstanding as of June 30, 2017. For the three months ended June 30, 2017, we included 371,632 of the outstanding stock options and 3,829,256 shares of restricted stock and PSUs in the computation of diluted earnings per share, on a weighted-average basis, as their inclusion was dilutive. For the six months ended June 30, 2017, we included 371,632 of the outstanding stock options and 3,474,721 shares of restricted stock and PSUs in the computation of diluted earnings per share, on a weighted-average basis, as their inclusion was dilutive. The remaining shares of restricted stock and PSUs are antidilutive, and as such, they were properly excluded.

14. Fair Value of Financial Instruments

The following tables present our financial assets that are measured at fair value on a recurring basis as of June 30, 2018 and December 31, 2017. We did not have any financial liabilities measured at fair value on a recurring basis as of June 30, 2018 and December 31, 2017.

	June 30, 2018
	Total		Level 1		Level 2		Level 3
	(in millions)
Financial investments, at fair value	$	313	$	128	$	185	$	—
Default fund and margin deposit investments	1,607		54		1,553		—
Total	$	1,920	$	182	$	1,738	$	—

	December 31, 2017
	Total		Level 1		Level 2		Level 3
	(in millions)
Financial investments, at fair value	$	235	$	135	$	100	$	—
Default fund and margin deposit investments	2,129		371		1,758		—
Total	$	2,364	$	506	$	1,858	$	—

As of June 30, 2018 and December 31, 2017, Level 1 financial investments, at fair value were primarily comprised of trading securities, mainly highly rated European government debt securities. As of June 30, 2018 and December 31, 2017, Level 2 financial investments, at fair value were primarily comprised of trading securities, mainly time deposits, corporate bonds and European mortgage bonds. Of the Level 1 and Level 2 financial investments, at fair value, $153 million as of June 30, 2018 and $160 millio

27

n as of December 31, 2017 are assets utilized to meet regulatory capital requirements, primarily for our clearing operations at Nasdaq Clearing.

Our Level 1 default fund and margin deposit investments were primarily comprised of highly rated European government debt securities. Level 2 default fund and margin deposit investments were primarily comprised of central bank certificates and reverse repurchase agreements, as of June 30, 2018 and December 31, 2017.

See Note 15, “Clearing Operations,” for further discussion of default fund contributions and margin deposits.

There were no transfers between Level 1 and Level 2 of the fair value hierarchy as of June 30, 2018 and December 31, 2017. 

Financial Instruments Not Measured at Fair Value on a Recurring Basis

Some of our financial instruments are not measured at fair value on a recurring basis but are recorded at amounts that approximate fair value due to their liquid or short-term nature. Such financial assets and financial liabilities include: cash and cash equivalents, restricted cash, receivables, net, certain other current assets, accounts payable and accrued expenses, Section 31 fees payable to SEC, accrued personnel costs, commercial paper and certain other current liabilities.

Our investments in OCC and EuroCCP N.V. are accounted for under the equity method of accounting. Our investment in LCH.Clearnet Group Limited is accounted for using the measurement alternative as this investment does not have a readily determinable fair value. See “Equity Securities,” of Note 3, “Significant Accounting Policies Update,” and “Equity Method Investments,” and “Equity Securities,” of Note 7, “Investments,” for further discussion.

We also consider our debt obligations to be financial instruments. The fair value of our debt obligations, utilizing discounted cash flow analyses for our floating rate debt and prevailing market rates for our fixed rate debt, was $4.0 billion as of June 30, 2018 and $4.4 billion as of December 31, 2017. The discounted cash flow analyses are based on borrowing rates currently available to us for debt with similar terms and maturities. The fair value of our commercial paper approximates the carrying value since the rates of interest on this short-term debt approximate market rates as of June 30, 2018. Our commercial paper and our fixed rate and floating rate debt are categorized as Level 2 in the fair value hierarchy.

For further discussion of our debt obligations, see Note 9, “Debt Obligations.”

Non-Financial Assets Measured at Fair Value on a Non-Recurring Basis

Our non-financial assets, which include goodwill, intangible assets, and other long-lived assets, are not required to be carried at fair value on a recurring basis. Fair value measures of non-financial assets are primarily used in the impairment analysis of these assets. Any resulting asset impairment would require

that the non-financial asset be recorded at its fair value. Nasdaq uses Level 3 inputs to measure the fair value of the above assets on a non-recurring basis. As of June 30, 2018 and December 31, 2017, there were no non-financial assets measured at fair value on a non-recurring basis.

15. Clearing Operations

NasdaqClearing

Nasdaq Clearing is authorized and supervised under EMIR as a multi-asset clearinghouse by the SFSA and is authorized to conduct clearing operations in Norway by the Norwegian Ministry of Finance. The clearinghouse acts as the CCP for exchange and OTC trades in equity derivatives, fixed income derivatives, resale and repurchase contracts, power derivatives, emission allowance derivatives, freight and fuel oil derivatives, and seafood derivatives. 

Through our clearing operations in the financial markets, which include the resale and repurchase market, the commodities markets, and the seafood market, Nasdaq Clearing is the legal counterparty for, and guarantees the fulfillment of, each contract cleared. These contracts are not used by Nasdaq Clearing for the purpose of trading on its own behalf. As the legal counterparty of each transaction, Nasdaq Clearing bears the counterparty risk between the purchaser and seller in the contract. In its guarantor role, Nasdaq Clearing has precisely equal and offsetting claims to and from clearing members on opposite sides of each contract, standing as the CCP on every contract cleared. In accordance with the rules and regulations of Nasdaq Clearing, clearing members’ open positions are aggregated to create a single portfolio for which default fund and margin collateral requirements are calculated. See “Default Fund Contributions and Margin Deposits” below for further discussion of Nasdaq Clearing’s default fund and margin requirements.

Nasdaq Clearing maintains four member sponsored default funds: one related to financial markets, one related to commodities markets, one related to the seafood market, and a mutualized fund. Under this structure, Nasdaq Clearing and its clearing members must contribute to the total regulatory capital related to the clearing operations of Nasdaq Clearing. This structure applies an initial separation of default fund contributions for the financial, commodities and seafood markets in order to create a buffer for each market’s counterparty risks. Simultaneously, a mutualized default fund provides capital efficiencies to Nasdaq Clearing’s members with regard to total regulatory capital required. See “Default Fund Contributions” below for further discussion of Nasdaq Clearing’s default fund. Power of assessment and a liability waterfall also have been implemented. See “Power of Assessment” and “Liability Waterfall” below for further discussion. These requirements ensure the alignment of risk between Nasdaq Clearing and its clearing members.

Default Fund Contributions and Margin Deposits

As of June 30, 2018, clearing member default fund contributions and margin deposits were as follows:

	June 30, 2018
	Cash Contributions		Non-Cash Contributions		Total Contributions
	(in millions)
Default fund contributions	$	427	$	132	$	559
Margin deposits	4,014		4,038		8,052
Total	$	4,441	$	4,170	$	8,611

In accordance with its investment policy, of the total cash contributions of $4,441 million, Nasdaq Clearing has invested $913 million in highly rated European and U.S. government debt securities or central bank certificates with maturity dates primarily 90 days or less and $694 million in reverse repurchase agreements secured with highly rated government securities with maturity dates that range from 3 days to 22 days. The carrying value of these securities approximates their fair value due to the short-term nature of the instruments and reverse repurchase agreements. The remainder of this balance was held in cash in demand deposit accounts at central banks and large, highly rated financial institutions. Of the total default fund contributions of $559 million, Nasdaq Clearing can utilize $489 million as capital resources in the event of a counterparty default. The remaining balance of $70 million pertains to member posted surplus balances.

In the investment activity related to default fund and margin contributions, we are exposed to counterparty risk related to reverse repurchase agreement transactions, which reflect the risk that the counterparty might become insolvent and, thus, fail to meet its obligations to our clearinghouse. We mitigate this risk by only engaging in transactions with high credit quality reverse repurchase agreement counterparties and by limiting the acceptable collateral under the reverse repurchase agreement to high quality issuers, primarily government securities and other securities explicitly guaranteed by a government. The value of the underlying security is monitored during the lifetime of the contract and in the event the market value of the underlying security falls below the reverse repurchase amount our clearinghouse requires additional collateral or a reset of the contract.

Default Fund Contributions

Contributions made to the default funds are proportional to the exposures of each clearing member. When a clearing member is active in more than one market, contributions must be made to all markets’ default funds in which the member is active. Clearing members’ eligible contributions may include cash and non-cash contributions. Cash contributions received are held in cash or invested by Nasdaq Clearing, in accordance with its investment policy, either in highly rated government debt securities, time deposits, central bank certificates or reverse repurchase agreements with highly rated government debt securities as collateral. Nasdaq Clearing maintains and manages

all cash deposits related to margin collateral. All risks and rewards of collateral ownership, including interest, belong to Nasdaq Clearing. Clearing members’ cash contributions are included in default funds and margin deposits in the Condensed Consolidated Balance Sheets as both a current asset and a current liability. Non-cash contributions include highly rated government debt securities that must meet specific criteria approved by Nasdaq Clearing. Non-cash contributions are pledged assets that are not recorded in the Condensed Consolidated Balance Sheets as Nasdaq Clearing does not take legal ownership of these assets and the risks and rewards remain with the clearing members. These balances may fluctuate over time due to changes in the amount of deposits required and whether members choose to provide cash or non-cash contributions. Assets pledged are held at a nominee account in Nasdaq Clearing’s name for the benefit of the clearing members and are immediately accessible by Nasdaq Clearing in the event of a default. In addition to clearing members’ required contributions to the liability waterfall, Nasdaq Clearing is also required to contribute capital to the liability waterfall and overall regulatory capital as specified under its clearinghouse rules. As of June 30, 2018, Nasdaq Clearing committed capital totaling $108 million to the liability waterfall and overall regulatory capital, in the form of government debt securities, which are recorded as financial investments, at fair value in the Condensed Consolidated Balance Sheets. The combined regulatory capital of the clearing members and Nasdaq Clearing will serve to secure the obligations of a clearing member and may be used to cover losses sustained by a clearing member in the event of a default.

Margin Deposits

Nasdaq Clearing requires all clearing members to provide collateral, which may consist of cash and non-cash contributions, to guarantee performance on the clearing members’ open positions, or initial margin. In addition, clearing members must also provide collateral to cover the daily margin call if needed. See “Default Fund Contributions” above for further discussion of cash and non-cash contributions.

Similar to default fund contributions, Nasdaq Clearing maintains and manages all cash deposits related to margin collateral. All risks and rewards of collateral ownership, including interest, belong to Nasdaq Clearing. These cash deposits are recorded in default funds and margin deposits in the Condensed Consolidated Balance Sheets as both a current asset and current liability. Pledged margin collateral is not recorded in our Condensed Consolidated Balance Sheets as all risks and rewards of collateral ownership, including interest, belong to the counterparty. Assets pledged are held at a nominee account in Nasdaq Clearing’s name for the benefit of the clearing members and are immediately accessible by Nasdaq Clearing in the event of a default.

Nasdaq Clearing marks to market all outstanding contracts and requires payment from clearing members whose positions have lost value. The mark-to-market process helps identify any clearing members that may not be able to satisfy their financial obligations in a timely manner allowing Nasdaq Clearing the

29

ability to mitigate the risk of a clearing member defaulting due to exceptionally large losses. In the event of a default, Nasdaq Clearing can access the defaulting member’s margin deposits to cover the defaulting member’s losses.

Regulatory Capital and Risk Management Calculations

Nasdaq Clearing manages risk through a comprehensive counterparty risk management framework, which is comprised of policies, procedures, standards and financial resources. The level of regulatory capital is determined in accordance with Nasdaq Clearing’s regulatory capital policy, as approved by the SFSA. Regulatory capital calculations are continuously updated through a proprietary capital-at-risk calculation model that establishes the appropriate level of capital.

As mentioned above, Nasdaq Clearing is the legal counterparty for each contract traded and thereby guarantees the fulfillment of each contract. Nasdaq Clearing accounts for this guarantee as a performance guarantee. We determine the fair value of the performance guarantee by considering daily settlement of contracts and other margining and default fund requirements, the risk management program, historical evidence of default payments, and the estimated probability of potential default payouts. The calculation is determined using proprietary risk management software that simulates gains and losses based on historical market prices, extreme but plausible market scenarios, volatility and other factors present at that point in time for those particular unsettled contracts. Based on this analysis, the estimated liability was nominal and no liability was recorded as of June 30, 2018. 

The market value of derivative contracts outstanding prior to netting was as follows:

	June 30, 2018
	(in millions)
Commodity and seafood options, futures and forwards(1)(2)(3)	$	1,447
Fixed-income options and futures(1)(2)	763
Stock options and futures(1)(2)	260
Index options and futures(1)(2)	80
Total	$	2,550

____________

⁽¹⁾  We determined the fair value of our option contracts using standard valuation models that were based on market-based observable inputs including implied volatility, interest rates and the spot price of the underlying instrument.

⁽²⁾  We determined the fair value of our futures contracts based upon quoted market prices and average quoted market yields.

⁽³⁾  We determined the fair value of our forward contracts using standard valuation models that were based on market-based observable inputs including LIBOR rates and the spot price of the underlying instrument.

The total number of derivative contracts cleared through Nasdaq Clearing for the six months ended June 30, 2018 and 2017 was as follows:

	June 30, 2018	June 30, 2017
Commodity and seafood options, futures and forwards(1)	1,162,716	1,397,771
Fixed-income options and futures	11,286,397	10,160,127
Stock options and futures	11,940,062	13,526,164
Index options and futures	24,641,397	21,616,323
Total	49,030,572	46,700,385

____________

(1) The total volume in cleared power related to commodity contracts was 577 Terawatt hours (TWh) for the six months ended June 30, 2018 and 647 TWh for the six months ended June 30, 2017.

The outstanding contract value of resale and repurchase agreements was $3.4 billion as of June 30, 2018 and $4.4 billion as of June 30, 2017. The total number of contracts cleared was 4,498,651 for the six months ended June 30, 2018 and was 3,953,901 for the six months ended June 30, 2017.

Power of Assessment 

To further strengthen the contingent financial resources of the clearinghouse, Nasdaq Clearing has power of assessment that provides the ability to collect additional funds from its clearing members to cover a defaulting member’s remaining obligations up to the limits established under the terms of the clearinghouse rules. The power of assessment corresponds to 100.0% of the clearing member’s aggregate contribution to the financial, commodities and seafood markets’ default funds.

Liability Waterfall

The liability waterfall is the priority order in which the capital resources would be utilized in the event of a default where the defaulting clearing member’s collateral would not be sufficient to cover the cost to settle its portfolio. If a default occurs and the defaulting clearing member’s collateral, including cash deposits and pledged assets, is depleted, then capital is utilized in the following amount and order:

• junior capital contributed by Nasdaq Clearing, which totaled $16 million as of June 30, 2018;

• a loss sharing pool related only to the financial market that is contributed to by clearing members and only applies if the defaulting member’s portfolio includes interest rate swap products;

• specific market default fund where the loss occurred (i.e., the financial, commodities, or seafood market), which includes capital contributions of the clearing members on a pro-rata basis;

• senior capital contributed to each specific market by Nasdaq Clearing, calculated in accordance with

30

clearinghouse rules, which totaled $23 million as of June 30, 2018; and

• mutualized default fund, which includes capital contributions of the clearing members on a pro-rata basis.

In addition to the capital held to withstand counterparty defaults described above, Nasdaq Clearing also has committed capital of $69 million to ensure that it can handle an orderly wind-down of its operation, and that it is adequately protected against investment, operational, legal, and business risks. If additional funds are needed after utilization of the mutualized default fund, then Nasdaq Clearing will utilize its power of assessment and additional capital contributions will be required by non-defaulting members up to the limits established under the terms of the clearinghouse rules.

16. Commitments, Contingencies and Guarantees

Guarantees Issued and Credit Facilities Available

In addition to the default fund contributions and margin collateral pledged by clearing members discussed in Note 15, “Clearing Operations,” we have obtained financial guarantees and credit facilities which are guaranteed by us through counter indemnities, to provide further liquidity related to our clearing businesses. Financial guarantees issued to us totaled $12 million as of June 30, 2018 and $14 million as of December 31, 2017. As discussed in “Other Credit Facilities,” of Note 9, “Debt Obligations,” clearing-related credit facilities, which are available in multiple currencies, totaled $218 million as of June 30, 2018 and $187 million as of December 31, 2017, in available liquidity, none of which was utilized.

Execution Access is an introducing broker which operates the trading platform for our Fixed Income business to trade in U.S. Treasury securities. Execution Access has a clearing arrangement with Cantor Fitzgerald. As of June 30, 2018, we have contributed $19 million of clearing deposits to Cantor Fitzgerald in connection with this clearing arrangement. This clearing agreement ended on July 31, 2018, and has been replaced by a clearing agreement with the Industrial and Commercial Bank of China Financial Services LLC, or ICBC, where all trades have cleared since June 25, 2018. As a result, we also have contributed $15 million of clearing deposits to ICBC. These deposits are recorded in other current assets in our Condensed Consolidated Balance Sheets. In July 2018, the majority of the clearing deposit of $19 million which was contributed to Cantor Fitzgerald has been reimbursed. Some of the trading activity in Execution Access is cleared by ICBC through the Fixed Income Clearing Corporation, with ICBC acting as agent. Execution Access assumes the counterparty risk of clients that do not clear through the Fixed Income Clearing Corporation. Counterparty risk of clients exists for Execution Access between the trade date and the settlement date of the individual transactions, which is at least one business day (or more, if specified by the U.S. Treasury issuance calendar). Counterparties that do not clear through the Fixed Income Clearing Corporation are subject to a credit due diligence process and may be required to post collateral, provide principal letters, or provide other forms of credit enhancement

to Execution Access for the purpose of mitigating counterparty risk. Daily position trading limits are also enforced for such counterparties.

We believe that the potential for us to be required to make payments under these arrangements is mitigated through the pledged collateral and our risk management policies. Accordingly, no contingent liability is recorded in the Condensed Consolidated Balance Sheets for these arrangements. However, no guarantee can be provided that these arrangements will at all times be sufficient.

Lease Commitments

We lease some of our office space under non-cancelable operating leases with third parties and sublease office space to third parties. Some of our lease agreements contain renewal options and escalation clauses based on increases in property taxes and building operating costs.

Other Guarantees

We have provided other guarantees of $2 million as of June 30, 2018 and $3 million as of December 31, 2017. These guarantees are primarily related to obligations for our rental and leasing contracts as well as performance guarantees on certain market technology contracts related to the delivery of software technology and support services. We have received financial guarantees from various financial institutions to support the above guarantees.

Through our clearing operations in the financial markets, Nasdaq Clearing is the legal counterparty for, and guarantees the performance of, its clearing members. See Note 15, “Clearing Operations,” for further discussion of Nasdaq Clearing performance guarantees.

We have provided a guarantee related to lease obligations for The Nasdaq Entrepreneurial Center, Inc. which is a not-for-profit organization designed to convene, connect and engage aspiring and current entrepreneurs. This entity is not included in the consolidated financial statements of Nasdaq.

We believe that the potential for us to be required to make payments under these arrangements is unlikely. Accordingly, no contingent liability is recorded in the Condensed Consolidated Balance Sheets for the above guarantees.

31

Non-Cash Contingent Consideration 

As part of the purchase price consideration of a prior acquisition, we have agreed to future annual issuances of 992,247 shares of Nasdaq common stock which approximated certain tax benefits associated with the transaction. Such contingent future issuances of Nasdaq common stock will be paid ratably through 2027 if Nasdaq’s total gross revenues equal or exceed $25 million in each such year. The contingent future issuances of Nasdaq common stock are subject to anti-dilution protections and acceleration upon certain events.

Escrow Agreements

In connection with prior acquisitions, we entered into escrow agreements to secure the payment of post-closing adjustments and to ensure other closing conditions. As of June 30, 2018, these escrow agreements provide for future payment of $13 million, of which $9 million is included in other current liabilities and $4 million is included in other non-current liabilities in the Condensed Consolidated Balance Sheets.

Routing Brokerage Activities

One of our broker-dealer subsidiaries, Nasdaq Execution Services, provides a guarantee to securities clearinghouses and exchanges under its standard membership agreements, which require members to guarantee the performance of other members. If a member becomes unable to satisfy its obligations to a clearinghouse or exchange, other members would be required to meet its shortfalls. To mitigate these performance risks, the exchanges and clearinghouses often require members to post collateral, as well as meet certain minimum financial standards. Nasdaq Execution Services’ maximum potential liability under these arrangements cannot be quantified. However, we believe that the potential for Nasdaq Execution Services to be required to make payments under these arrangements is unlikely. Accordingly, no contingent liability is recorded in the Condensed Consolidated Balance Sheets for these arrangements.

Other Commitments

We have a 40.0% ownership in OCC. Under the OCC's capital plan, the OCC shareholders have committed to contribute up to $200 million in equity capital if certain capital thresholds are breached, including up to $80 million to be contributed by Nasdaq. See “Equity Method Investments,” of Note 7, “Investments,” for further discussion of our equity method investment in OCC.

Legal and Regulatory Matters 

As previously disclosed, we are named as one of many defendants in City of Providence v. BATS Global Markets, Inc., et al., 14 Civ. 2811 (S.D.N.Y.), which was filed on April 18, 2014 in the United States District Court for the Southern District of New York. The district court appointed lead counsel, who filed an amended complaint on September 2, 2014. The amended complaint names as defendants seven national exchanges, as well as Barclays PLC, which operated a private alternative trading system. On behalf of a putative class of

securities traders, the plaintiffs allege that the defendants engaged in a scheme to manipulate the markets through high-frequency trading; the amended complaint asserts claims against us under Section 10(b) of the Exchange Act and Rule 10b-5, as well as under Section 6(b) of the Exchange Act. The plaintiffs seek injunctive and monetary relief of an unspecified amount. We filed a motion to dismiss the amended complaint on November 3, 2014. In response, the plaintiffs filed a second amended complaint on November 24, 2014, which names the same defendants and alleges essentially the same violations. We then filed a motion to dismiss the second amended complaint on January 23, 2015. On August 26, 2015, the district court entered an order dismissing the second amended complaint in its entirety with prejudice, concluding that most of the plaintiffs’ theories were foreclosed by absolute immunity and in any event that the plaintiffs failed to state any claim. The plaintiffs appealed the judgment of dismissal to the United States Court of Appeals for the Second Circuit. On December 19, 2017, the Second Circuit issued an opinion vacating the district court’s judgment of dismissal and remanding to the district court for further proceedings. The exchanges filed a petition before the Second Circuit seeking panel or en banc rehearing on January 31, 2018, which the Second Circuit denied on March 13, 2018. On May 18, 2018, the exchanges filed a motion to dismiss the amended complaint, raising issues not addressed in the proceedings to date. Given the preliminary nature of the proceedings, we are unable to estimate what, if any, liability may result from this litigation. However, we believe that the claims are without merit and will continue to litigate vigorously.

Except as disclosed above and in prior reports filed under the Exchange Act, we are not currently a party to any litigation or proceeding that we believe could have a material adverse effect on our business, consolidated financial condition, or operating results. However, from time to time, we have been threatened with, or named as a defendant in, lawsuits or involved in regulatory proceedings.

In the normal course of business, Nasdaq discusses matters with its regulators raised during regulatory examinations or otherwise subject to their inquiry and oversight. These matters could result in censures, fines, penalties or other sanctions. Management believes the outcome of any resulting actions will not have a material impact on its consolidated financial position or results of operations. However, we are unable to predict the outcome or the timing of the ultimate resolution of these matters, or the potential fines, penalties or injunctive or other equitable relief, if any, that may result from these matters.

Tax Audits

We are engaged in ongoing discussions and audits with taxing authorities on various tax matters, the resolutions of which are uncertain. Currently, there are matters that may lead to assessments, some of which may not be resolved for several years. Based on currently available information, we believe we have adequately provided for any assessments that could result from those proceedings where it is more likely than not that we

32

will be assessed. We review our positions on these matters as they progress.

17. Income Taxes

We use the asset and liability method to determine income taxes on all transactions recorded in the consolidated financial statements. Deferred tax assets (net of valuation allowances) and deferred tax liabilities are presented net by jurisdiction as either a non-current asset or liability in our Condensed Consolidated Balance Sheets, as appropriate. Deferred tax assets and liabilities are determined based on differences between the financial statement carrying amounts and the tax basis of existing assets and liabilities (i.e., temporary differences) and are measured at the enacted rates that will be in effect when these differences are realized. If necessary, a valuation allowance is established to reduce deferred tax assets to the amount that is more likely than not to be realized. As of June 30, 2018 and December 31, 2017, net deferred tax assets are included in other non-current assets in the Condensed Consolidated Balance Sheets.

In order to recognize and measure our unrecognized tax benefits, management determines whether a tax position is more likely than not to be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. Once it is determined that a position meets the recognition thresholds, the position is measured to determine the amount of benefit to be recognized in the consolidated financial statements. Interest and/or penalties related to income tax matters are recognized in income tax expense.

The following table shows our income tax provision and effective tax rate:

	Three Months Ended June 30,						Percentage Change
	2018			2017
	($ in millions)
Income tax provision	$	126		$	65		93.8	%
Effective tax rate	43.8		%	30.8		%
	Six Months Ended June 30,						Percentage Change
	2018			2017
	($ in millions)
Income tax provision	$	188		$	113		66.4	%
Effective tax rate	35.7		%	26.5		%

The higher effective tax rate in the second quarter and first six months of 2018 when compared with the same periods in 2017 is primarily due to the reversal of certain Swedish tax benefits recorded in prior periods and the tax expense associated with the sale of the Public Relations Solutions and Digital Media Services businesses. Also, we recorded a lower recognition of excess tax benefits associated with the vesting of employee share-based compensation arrangements in the first six months of 2018 compared to the same period in 2017. These increases are partially offset by a decrease in tax expense due to the reduction of the U.S. corporate tax rate from 35% to 21%, effective January 1, 2018.

The effective tax rate may also vary from period to period depending on, among other factors, the geographic and business mix of earnings and losses. These same and other factors, including history of pre-tax earnings and losses, are taken into account in assessing the ability to realize deferred tax assets.

Nasdaq and its eligible subsidiaries file a consolidated U.S. federal income tax return and applicable state and local income tax returns and non-U.S. income tax returns. Federal income tax returns for the years 2012 through 2015 are currently under examination by the Internal Revenue Services and we are subject to examination by the Internal Revenue Service for 2016. Several state tax returns are currently under examination by the respective tax authorities for the years 2005 through 2016. Non-U.S. tax returns are subject to examination by the respective tax authorities for the years 2009 through 2016. Although the results of such examinations may have an impact on our unrecognized tax benefits, we do not anticipate that such impact will be material to our consolidated financial position or results of operations. In addition, we anticipate that the amount of unrecognized tax benefits as of June 30, 2018 will decrease in the next twelve months as we expect to settle certain tax audits.

The Swedish Tax Agency has disallowed certain interest expense deductions for the years 2013 - 2016. We appealed to the Lower Administrative Court for the years 2013 - 2015. In the first quarter of 2018, the Lower Administrative Court denied our appeal. We have appealed to the Administrative Court of Appeal. Through March 31, 2018, we had recorded tax benefits of $57 million associated with this matter. We continue to pay all assessments from the Swedish Tax Agency while this matter is pending and have paid $40 million through June 30, 2018. In the second quarter of 2018, the Administrative Court of Appeal decided similar cases against other taxpayers. Although we continue to assert the validity of these interest expense deductions, the decisions of the court lead us to conclude that we can no longer assert that we are more than likely to be successful in our appeal. As such, in the second quarter of 2018, we recorded tax expense of $41 million, or $0.24 per diluted share, which is net of any related U.S. tax benefits and reflects the impact of foreign currency translation. We expect to record future quarterly net tax expense of $1 million related to this matter.

The Tax Cuts and Jobs Act was enacted on December 22, 2017 and was effective January 1, 2018. The new legislation contains several key provisions, including a reduction of the U.S. corporate income tax rate from 35% to 21%. We were required to remeasure all of our U.S. deferred tax assets and liabilities as of December 22, 2017 and record the impact of such remeasurement in our 2017 financial statements. For the year ended December 31, 2017, we recorded a decrease to tax expense of $89 million, substantially all of which reflects the estimated impact associated with the remeasurement of our net U.S. deferred tax liability at the lower U.S. federal corporate income tax rate. The Tax Cuts and Jobs Act also imposes a transition tax on unremitted aggregate accumulated earnings of non-U.S. subsidiaries, which did not impact us.

33

SEC Staff Accounting Bulletin No. 118, “Income Tax Accounting Implications of the Tax Cuts and Jobs Act,” has provided guidance which allows us to record provisional amounts during a measurement period not to extend beyond one year of the enactment date. As of December 31, 2017, we recorded a provisional estimate of the effects of the new legislation. In the first quarter of 2018, we recorded an increase to tax expense of $5 million, which reflects the reduced federal tax benefit associated with state unrecognized tax benefits. We will continue to analyze the Tax Cuts and Jobs Act and related accounting guidance and interpretations in order to finalize any impacts within the measurement period.

On January 1, 2018, we adopted Topic 220. See “Recent Accounting Pronouncements,” of Note 2, “Basis of Presentation and Principles of Consolidation,” for further discussion of this standard. As a result of the adoption of this standard, in the first quarter of 2018, we recorded a reclassification of $142 million for stranded tax effects related to the Tax Cuts and Jobs Act from accumulated other comprehensive loss to retained earnings within stockholders’

equity in the Condensed Consolidated Balance Sheets. Of the $142 million of stranded tax effects, $135 million relates to the effect on net foreign currency translation gains and losses and $7 million relates to the effect on employee benefit plan adjustment gains and losses.

18. Business Segments

We manage, operate and provide our products and services in four business segments: Market Services, Corporate Services, Information Services and Market Technology. See Note 1, “Organization and Nature of Operations,” for further discussion of our reportable segments.

Our management allocates resources, assesses performance and manages these businesses as four separate segments. We evaluate the performance of our segments based on several factors, of which the primary financial measure is operating income. Results of individual businesses are presented based on our management accounting practices and structure.

* * * * * *

The following table presents certain information regarding our operating segments for the three and six months ended June 30, 2018 and 2017:

Certain amounts are allocated to corporate items in our management reports based on the decision that those activities should not be used to evaluate the segment’s ongoing operating performance. We have included in corporate items the revenues and expenses of the Public Relations Solutions and Digital

Media Services businesses which were part of the Corporate Solutions business within our Corporate Services segment as these businesses were sold in April 2018. See “2018 Divestiture,” of Note 4, “Divestiture and Acquisitions,” for

34

further discussion. In addition, the following items are allocated to corporate items for segment reporting purposes:

Amortization expense of acquired intangible assets: We amortize intangible assets acquired in connection with various acquisitions. Intangible asset amortization expense can vary from period to period due to episodic acquisitions completed, rather than from our ongoing business operations. As such, if intangible asset amortization is included in performance measures, it is more difficult to assess the day-to-day operating performance of the segments, and the relative operating performance of the segments between periods. Management does not consider intangible asset amortization expense for the purpose of evaluating the performance of our segments or their managers or when making decisions to allocate resources. Therefore, we believe performance measures excluding intangible asset amortization expense provide management with a more useful representation of our segments' ongoing activity in each period.

Merger and strategic initiatives expense:We have pursued various strategic initiatives and completed a divestiture and a number of acquisitions in recent years which have resulted in expenses which would not have otherwise been incurred. These

expenses generally include integration costs, as well as legal, due diligence and other third party transaction costs. The frequency and the amount of such expenses vary significantly based on the size, timing and complexity of the transaction. Accordingly, we do not allocate these costs for purposes of disclosing segment results because they do not contribute to a meaningful evaluation of a particular segment’s ongoing operating performance.

Other significant items: We have excluded certain other charges or gains that are the result of other non-comparable events to measure operating performance. For the three and six months ended June 30, 2018, other significant items included a sales and use tax charge which related to prior periods. For the six months ended June 30, 2018, other significant items also included a sublease loss reserve charge recorded on space we currently occupy due to excess capacity. For the three and six months ended June 30, 2017, other significant items included loss on extinguishment of debt. We believe the exclusion of such amounts allows management and investors to better understand the financial results of Nasdaq.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results ofOperations.

The following discussion and analysis of the financial condition and results of operations of Nasdaq should be read in conjunction with our condensed consolidated financial statements and related notes included in this Form 10-Q.

Business Overview

We are a leading provider of trading, clearing, marketplace technology, regulatory, securities listing, information and public and private company services. Our global offerings are diverse and include trading and clearing across multiple asset classes, trade management services, market data products, financial indexes, capital formation solutions, corporate solutions, and market technology products and services. Our technology powers markets across the globe, supporting equity derivative trading, clearing and settlement, cash equity trading, fixed income trading, trading surveillance and many other functions.

Business Environment

Our non-transactional businesses provide technology to exchanges, clearing organizations and central securities depositories around the world. We also offer companies and other organizations access to innovative products, software solutions and services that increase transparency, mitigate risk, improve board efficiency and facilitate better corporate governance. In our transactional businesses, we serve listed companies, market participants and investors by providing derivative, commodities, cash equity, and fixed income markets, as well as clearing services, thereby facilitating economic growth and corporate entrepreneurship. In broad terms, our business performance is impacted by a number of drivers including macroeconomic events affecting the risk and return of financial assets, investor sentiment, government and private sector demands for capital, the regulatory environment for capital markets, changing technology, particularly in the financial services industry, and changes in investment patterns and priorities. Our future revenues and net income will continue to be influenced by a number of domestic and international economic trends including, among others:

• the demand by companies and other organizations for the products sold by our Corporate Solutions business, whichis largely driven by the overall state of the economy and the attractiveness of our offerings;

• the challenges created by the automation of market data consumption, including competition and the quickly evolving nature of the market data business;

• the outlook of our technology customers for capital market activity;

• technological advances and members’ and customers’ demand for speed, efficiency, and reliability;

• the acceptance of cloud-based services and advanced analytics by our customers and global regulators;

• trading volumes and values in equity derivative, cash equity and FICC, which are driven primarily by overall macroeconomic conditions;

• the number of companies seeking equity financing, which is affected by factors such as investor demand, the global economy, and availability of diverse sources of financing, as well as tax and regulatory policies;

• the demand for information about, or access to, our markets, which is dependent on the products we trade, our importance as a liquidity center, and the quality and pricing of our market data and trade management services;

• the demand for licensed ETPs, enhanced analytics and other financial products based on our indexes as well as changes to the underlying assets associated with existing licensed financial products;

• continuing pressure in transaction fee pricing due to intense competition in the U.S. and Europe;

• competition related to pricing, product features and service offerings; and

• regulatory changes relating to market structure or affecting certain types of instruments, transactions, pricing structures or capital market participants.

The current consensus forecast for gross domestic product growth for the U.S. is 2.9% in 2018 and 2.6% in 2019 and the Eurozone is 2.2% in 2018 and 1.8% in 2019. U.S. growth forecasts for 2018 have continued to rise since the middle of 2017 and are currently 0.6 percentage points higher than the lowest forecast of 2.3% in July 2017. Growth forecasts for the Eurozone in 2018 had been steadily rising since an estimate of 1.5% at the start of 2017, but have fallen by 0.2 percentage points in recent months. While growth is accelerating, there are a number of significant structural and political issues continuing to impact the global economy. In the U.S., the yield curve continues to flatten as the Federal Reserve continues to tighten monetary policy. Volatility and trading volumes remained elevated in the second quarter of 2018 compared with the same period in 2017, although both were lower compared to the first quarter of 2018.

In the U.S., the second quarter of 2018 was a strong quarter for IPOs, with 56 IPOs on The Nasdaq Stock Market compared with 36 in the second quarter of 2017. In addition, there were 22 IPOs in the second quarter of 2018 on the exchanges that comprise Nasdaq Nordic and Nasdaq Baltic compared with 39 in the second quarter of 2017. Additional impacts on our business drivers include the international enactment and implementation of legislative and regulatory initiatives, notably MiFID II in Europe, the evolution of market participants’ trading and investment strategies, and the continued rapid progression and deployment of new technology in the financial services industry. The business environment that influences our financial performance in 2018 may be characterized as follows:

• rapidly evolving technology for our businesses and their clients;

36

• increased demand for applications using emerging technologies and sophisticated analytics by both new entrants and industry incumbents;

• the expansion of the number of industries, and emergence of new industries, seeking to use advanced market technology;

• intense competition among U.S. exchanges and dealer-owned systems for cash equity trading and strong competition between MTFs and exchanges in Europe for cash equity trading; and

• globalization of exchanges, customers and competitors extending the competitive horizon beyond national markets.

Business Segments

We manage, operate and provide our products and services in four business segments: Market Services, Corporate Services, Information Services and Market Technology. See Note 1, “Organization and Nature of Operations,” and Note 18, “Business Segments,” to the condensed consolidated financial statements for further discussion of our reportable segments, as well as how management allocates resources, assesses performance and manages these businesses as four separate segments.

Financial Summary

The following table summarizes our financial performance for the three and six months ended June 30, 2018 when compared with the same periods in 2017.

____________

⁽¹⁾  Includes Section 31 fees of $9 million in the second quarter of 2018, $23 million in the first six months of 2018, $9 million in the second quarter of 2017, and $18 million in the first six months of 2017. Section 31 fees are recorded as equity derivative trading and clearing revenues with a corresponding amount recorded in transaction-based expenses. 

⁽²⁾  Includes Section 31 fees of $89 million in the second quarter of 2018, $204 million in the first six months of 2018, $80 million in the second quarter of 2017, and $152 million in the first six months of 2017. Section 31 fees are recorded as cash equity trading revenues with a corresponding amount recorded in transaction-based expenses.   

Equity Derivative Trading and Clearing Revenues

Equity derivative trading and clearing revenues and equity derivative trading and clearing revenues less transaction-based expenses increased in the second quarter and first six months of 2018 compared with the same periods in 2017. 

The increases were primarily due to higher U.S. industry trading volumes, partially offset by a decrease in our overall U.S. matched market share. Further impacting the increase in equity derivative trading revenues in the first six months of 2018 were higher Section 31 pass-through fees.

Section 31 fees are recorded as equity derivative trading and clearing revenues with a corresponding amount recorded as transaction-based expenses. In the U.S., we are assessed these fees from the SEC and pass them through to our customers in

the form of incremental fees. Pass-through fees can increase or decrease due to rate changes by the SEC, our percentage of the overall industry volumes processed on our systems, and differences in actual dollar value of shares traded. Since the amount recorded in revenues is equal to the amount recorded as transaction-based expenses, there is no impact on our revenues less transaction-based expenses. The increase in the first six months of 2018 compared with the same period in 2017 was primarily due to higher dollar value traded, partially offset by lower SEC fee rates.

Transaction rebates, in which we credit a portion of the per share execution charge to the market participant, increased in the second quarter and first six months of 2018 compared with the same periods in 2017 primarily due to higher U.S. industry

42

trading volumes, partially offset by a decrease in our overall U.S. matched market share.

Brokerage, clearance and exchange fees increased in the second quarter and first six months of 2018 compared with the same periods in 2017 primarily due to higher Section 31 pass-through fees associated with higher U.S. industry trading volumes.

Cash Equity Trading Revenues

Cash equity trading revenues and cash equity trading revenues less transaction-based expenses increased in the second quarter and first six months of 2018 compared with the same periods in 2017.

The increases in cash equity trading revenues were primarily due to:

• an increase in our overall U.S. matched market share executed on Nasdaq's exchanges; and

• an increase in Section 31 pass-through fees, partially offset by;

• a decrease in the U.S. average capture rate.

Further impacting the increase in cash equity trading revenues for the first six months of 2018 was higher U.S. trading volumes.

The increases in cash equity trading revenues less transaction-based expenses were primarily due to:

• an increase in our overall U.S. matched market share executed on Nasdaq's exchanges; and

• an increase in the U.S. average net capture rate.

The increases in the first six months of 2018 for both cash equity trading revenues and cash equity trading revenues less transaction-based expenses were also due to a favorable impact from foreign exchange of $4 million.

Similar to equity derivative trading and clearing, in the U.S. we record Section 31 fees as cash equity trading revenues with a corresponding amount recorded as transaction-based expenses. We are assessed these fees from the SEC and pass them through to our customers in the form of incremental fees. Since the

amount recorded as revenues is equal to the amount recorded as transaction-based expenses, there is no impact on our revenues less transaction-based expenses. The increases in Section 31 fees in the second quarter and first six months of 2018 compared with the same periods in 2017 were primarily due to higher dollar value traded on Nasdaq’s exchanges, partially offset by lower SEC fee rates.

Transaction rebates increased in the second quarter and first six months of 2018 compared with the same periods in 2017. For The Nasdaq Stock Market, Nasdaq PSX and Nasdaq Canada, we credit a portion of the per share execution charge to the market participant that provides the liquidity, and for Nasdaq BX, we credit a portion of the per share execution charge to the market participant that takes the liquidity. The increases were primarily due to an increase in our overall U.S. matched market share executed on Nasdaq’s exchanges.

Brokerage, clearance and exchange fees increased in the second quarter and first six months of 2018 compared with the same periods in 2017 primarily due to higher Section 31 pass-through fees, as discussed above.

FICC Revenues

FICC revenues for the second quarter of 2018 were flat and increased in the first six months of 2018 compared with the same periods in 2017. FICC revenues less transaction-based expenses increased in the second quarter and first six months of 2018 compared with the same periods in 2017. The increases were primarily due to higher net revenues at NFX. The increase in the first six months was also due to a favorable impact from foreign exchange of $3 million.

Trade Management Services Revenues

Trade management services revenues increased in the second quarter and first six months of 2018 compared with the same periods in 2017 primarily due to an increase in revenues from customer demand for third party connectivity. The increase in the first six months was also due to a favorable impact from foreign exchange of $2 million.

increase in board & leadership and governance, risk and compliance revenues and a favorable impact from foreign exchange of $3 million.

Listing ServicesRevenues

Listing services revenues increased in the second quarter and first six months of 2018 compared with the same periods in

2017 primarily due to higher U.S. annual listing fee revenues, partially offset by a decrease in U.S. listing of additional shares fees as a result of our all-inclusive annual listing fee program. The increase in the first six months was also due to a favorable impact from foreign exchange of $2 million.

Market Data Revenues

Market data revenues increased in both the second quarter and first six months of 2018 compared with the same periods in 2017 primarily due to growth in proprietary market data products revenues and collections relating to unreported usage. The increase in the second quarter also included a favorable impact from foreign exchange of $2 million and the increase in the first six months included a favorable impact from foreign exchange of $4 million.

Index Revenues

Index revenues increased in both the second quarter and first six months of 2018 compared with the same periods in 2017

primarily due to higher assets under management in ETPs linked to Nasdaq indexes and higher licensing revenues from futures trading volume related to the Nasdaq 100 Index.

Investment Data & Analytics Revenues

Investment data & analytics revenues increased in both the second quarter and first six months of 2018 compared with the same periods in 2017 primarily due to the inclusion of revenues associated with the acquisition of eVestment.

OTHER REVENUES

Other revenues include the revenues from the Public Relations Solutions and Digital Media Services businesses which were sold in April 2018. Prior to the sale date, these revenues were included in our Corporate Solutions business. See “2018 Divestiture,” of Note 4, “Divestiture and Acquisitions,” to the condensed consolidated financial statements for further discussion.

The increase in compensation and benefits expense in both the second quarter and first six months of 2018 was primarily due to overall higher compensation costs resulting from our 2017 acquisitions and higher compensation expense reflecting higher performance incentives, partially offset by lower compensation costs due to the sale of the Public Relations Solutions and Digital Media Services businesses. The increase in the second quarter also included an unfavorable impact from foreign exchange of $2 million and the increase in the first six months included an unfavorable impact from foreign exchange of $8 million.

Headcount decreased to 4,069 employees as of June 30, 2018 from 4,337 as of June 30, 2017 primarily due to the sale of the Public Relations Solutions and Digital Media Services businesses, partially offset by our acquisition of eVestment.

Professional and contract services expense decreased in the second quarter and first six months of 2018 primarily due to the sale of the Public Relations Solutions and Digital Media Services businesses, partially offset by additional expense associated with our 2017 acquisitions. The decrease in the first six months also included an unfavorable impact from foreign exchange of $2 million.

Computer operations and data communications expense was flat in the second quarter as higher market data feed costs due to higher volumes and higher software maintenance costs were offset by lower costs resulting from the sale of the Public Relations Solutions and Digital Media Services businesses. Computer operations and data communications expense increased in the first six months of 2018 primarily due to higher market data feed costs due to higher volumes and higher software maintenance costs, partially offset by lower costs resulting from the sale of the Public Relations Solutions and Digital Media Services businesses.

Occupancy expense was flat in the second quarter of 2018 as additional facility and rent costs associated with our 2017 acquisitions were offset by lower costs resulting from the sale of the Public Relations Solutions and Digital Media Services businesses. Occupancy expense increased in the first six months of 2018 primarily due to additional facility and rent costs associated with our 2017 acquisitions and higher costs associated with additional rental space, partially offset by lower costs from the sale of the Public Relations Solutions and Digital Media Services businesses.

The decrease in general, administrative and other expense in both the second quarter and first six months of 2018 was primarily due to a pre-tax charge of $10 million in the second quarter of 2017 which primarily included a make-whole redemption price premium paid on the early extinguishment of our 2018 Notes, partially offset by higher costs associated with our 2017 acquisitions, lower regulatory fine income and a sales and use tax charge.

Marketing and advertising expense increased in both the second quarter and first six months of 2018 primarily due to an increase in advertising spend.

The increase in depreciation and amortization expense in both the second quarter and first six months of 2018 was primarily due to additional amortization expense associated with software assets placed in service and acquired intangible assets related to our 2017 acquisitions.

The credit balance in merger and strategic initiative expense in the second quarter of 2018 relates to the reclass of costs incurred during the first quarter of 2018 to sell the Public Relations Solutions and Digital Media Services businesses. Since these businesses were sold during the second quarter of 2018, these costs have been included as a deduction to the gain on the sale of these businesses. Merger and strategic

45

initiatives expense in the second quarter and first six months of 2017 was primarily related to our acquisition of ISE.

Gain on Divestiture of Businesses, Net of Disposal Costs

In April 2018, we sold our Public Relations Solutions and Digital Media Services businesses, and recorded a pre-tax gain of $41 million, net of disposal costs ($19 million after tax). See “2018 Divestiture,” of Note 4, “Divestiture and Acquisitions,” to the condensed consolidated financial statements for further discussion.

Other Investment Income

Other investment income in the second quarter and first six months of 2018 primarily related to dividend income received on an equity security.

Net Income from Unconsolidated Investees

Net income from unconsolidated investees in the second quarter and first six months of 2018 and 2017 primarily relates to income recognized from our equity method investment in OCC. See “Equity Method Investments,” of Note 7, “Investments,” to the condensed consolidated financial statements for further discussion of our equity method investments. 

Tax Matters

The following table shows our income tax provision and effective tax rate:

	Three Months Ended June 30,						Percentage Change
	2018			2017
	($ in millions)
Income tax provision	$	126		$	65		93.8	%
Effective tax rate	43.8		%	30.8		%
	Six Months Ended June 30,						Percentage Change

Income tax provision	$	188		$	113		66.4	%
Effective tax rate	35.7		%	26.5		%

For further discussion of our tax matters, see Note 17, “Income Taxes,” to the condensed consolidated financial statements.

The effective tax rate may vary from period to period depending on, among other factors, the geographic and business mix of earnings and losses. These same and other factors, including history of pre-tax earnings and losses, are taken into account in assessing the ability to realize deferred tax assets.

46

In order to recognize and measure our unrecognized tax

benefits, management determines whether a tax position is more likely than not to be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. Once it is determined that a position meets the recognition thresholds, the position is measured to determine the amount of benefit to be recognized in the condensed consolidated financial statements. Interest and/or penalties related to income tax matters are recognized in income tax expense.

Non-GAAP Financial Measures

In addition to disclosing results determined in accordance with U.S. GAAP, we also have provided non-GAAP net income attributable to Nasdaq and non-GAAP diluted earnings per share. Management uses this non-GAAP information internally, along with U.S. GAAP information, in evaluating our performance and in making financial and operational decisions. We believe our presentation of these measures provides investors with greater transparency and supplemental data relating to our financial condition and results of operations. In addition, we believe the presentation of these measures is useful to investors for period-to-period comparisons of results as the items described below do not reflect ongoing operating performance.

These measures are not in accordance with, or an alternative to, U.S. GAAP, and may be different from non-GAAP measures used by other companies. Investors should not rely on any single financial measure when evaluating our business. We recommend investors review the U.S. GAAP financial measures included in this Quarterly Report on Form 10-Q, including our condensed consolidated financial statements and the notes thereto. When viewed in conjunction with our U.S. GAAP results and the accompanying reconciliation, we believe these non-GAAP measures provide greater transparency and a more complete understanding of factors affecting our business than U.S. GAAP measures alone.

We understand that analysts and investors regularly rely on non-GAAP financial measures, such as non-GAAP net income attributable to Nasdaq and non-GAAP diluted earnings per share, to assess operating performance. We use non-GAAP net income attributable to Nasdaq and non-GAAP diluted earnings per share because they highlight trends more clearly in our business that may not otherwise be apparent when relying solely on U.S. GAAP financial measures, since these measures eliminate from our results specific financial items that have less bearing on our ongoing operating performance. Non-GAAP net income attributable to Nasdaq for the periods presented below is calculated by adjusting for the following items:

Amortization expense of acquired intangible assets: We amortize intangible assets acquired in connection with various acquisitions. Intangible asset amortization expense can vary from period to period due to episodic acquisitions completed, rather than from our ongoing business operations. As such, if intangible asset amortization is included in performance measures, it is more difficult to assess the day-to-day operating performance of the businesses, the relative operating

performance of the businesses between periods, and the earnings power of Nasdaq. Performance measures excluding intangible asset amortization therefore provide investors with a more useful representation of our businesses’ ongoing activity in each period.

Merger and strategic initiatives expense: We have pursued various strategic initiatives and completed a divestiture and a number of acquisitions in recent years which have resulted in expenses which would not have otherwise been incurred. These expenses generally include integration costs, as well as legal, due diligence and other third party transaction costs. The frequency and the amount of such expenses vary significantly based on the size, timing and complexity of the transaction. Accordingly, we exclude these costs for purposes of calculating non-GAAP measures which provide a more meaningful analysis of Nasdaq’s ongoing operating performance or comparisons in Nasdaq’s performance between periods.

Other significant items: We have excluded certain other charges or gains, including certain tax items, that are the result of other non-comparable events to measure operating performance. We believe the exclusion of such amounts allows management and investors to better understand the ongoing financial results of Nasdaq. For the three and six months ended June 30, 2018, other significant items included the gain on divestiture of businesses, net of disposal costs which pertains to the sale of the Public Relations Solutions and Digital Media Services businesses and a sales and use tax charge which related to prior periods. For the six months ended June 30, 2018, other significant items also included a sublease loss reserve charge recorded on space we currently occupy due to excess capacity. For the three and six months ended June 30, 2017, other significant items included loss on extinguishment of debt and wind down costs associated with an equity method investment that was previously written off. We believe the exclusion of such amounts allows management and investors to better understand the financial results of Nasdaq.

Significant tax items: The adjustment to the income tax provision includes the tax impact of each non-GAAP adjustment. In addition, for the six months ended June 30, 2018, the adjustment to the income tax provision includes a $3 million increase to tax expense due to a remeasurement of our unrecognized tax benefits and for the three and six months ended June 30, 2017, includes a $4 million decrease to tax expense due to a remeasurement of our unrecognized tax benefits. Additional adjustments include the following items:

• For the three and six months ended June 30, 2018, we recorded a reversal of previously recognized certain Swedish tax benefits. See Note 17, “Income Taxes,” to the condensed consolidated financial statements for further discussion.

• The impact of the newly enacted U.S. tax legislation is related to the Tax Cuts and Jobs Act which was enacted on December 22, 2017. For the six months ended June 30, 2018, we recorded an increase to tax expense of $5 million, which reflects the reduced federal tax benefit associated

47

with state unrecognized tax benefits. This amount may be refined in the future as new information becomes available.

• For the six months ended June 30, 2018, we recorded excess tax benefits of $5 million related to employee share-based compensation which reflects the recognition

of income tax effects of share-based awards when awards vest or are settled. This item is subject to volatility and will vary based on the timing of the vesting of employee share-based compensation arrangements and fluctuation in our stock price.

Liquidity and Capital Resources

Historically, we have funded our operating activities and met our commitments through cash generated by operations, augmented by the periodic issuance of our common stock and debt. See Note 9, “Debt Obligations,” to the condensed consolidated financial statements for further discussion. Currently, our cost and availability of funding remain healthy.

As part of the purchase price consideration of a prior acquisition, Nasdaq has contingent future obligations to issue 992,247 shares of Nasdaq common stock annually which approximated certain tax benefits associated with the transaction of $484 million. Such contingent future issuances of Nasdaq common stock will be paid ratably through 2027 if Nasdaq’s total gross revenues equal or exceed $25 million in each such year. The contingent future issuances of Nasdaq common stock are subject to anti-dilution protections and acceleration upon certain events.

In April 2017, we entered into the 2017 Credit Facility which replaced a former credit facility. We also entered into a commercial paper program which enables us to borrow efficiently at reasonable short-term interest rates and is supported by our 2017 Credit Facility. See “Commercial Paper Program,” and “2017 Credit Facility,” of Note 9, “Debt Obligations,” to the condensed consolidated financial statements for further discussion.

As of June 30, 2018, no amounts were outstanding on the 2017 Credit Facility. The $4 million credit balance represents unamortized debt issuance costs. Of the $1 billion that is available for borrowing, 271 million provides liquidity support for the commercial paper program and for a letter of credit. As such, as of June 30, 2018, the total remaining amount available under the 2017 Credit Facility was $729 million.

In the near term, we expect that our operations and the availability under our revolving credit commitment and commercial paper program will provide sufficient cash to fund our operating expenses, capital expenditures, debt repayments, any share repurchases, and any dividends.

The value of various assets and liabilities, including cash and cash equivalents, receivables, accounts payable and accrued expenses, and commercial paper can fluctuate from month to month. Working capital (calculated as current assets less current liabilities) was $(421) million as of June 30, 2018, compared with $276 million as of December 31, 2017, a decrease of $697 million.Current asset balance changes increased working capital by $217 million, with increases in default funds and margin deposits, financial investments, at fair value, receivables, net, and restricted cash, partially offset by decreases in assets held for sale, cash and cash equivalents, and other current assets. Current liability balance changes decreased working capital by $914 million, due to increases in default funds and margin deposits, short-term debt as our 2019 Notes became due within one year in March 2018, deferred revenue, Section 31 fees payable to the SEC, and other current liabilities, partially offset by decreases in accrued personnel costs,

liabilities held for sale, and accounts payable and accrued expenses. Principal factors that could affect the availability of our internally-generated funds include:

• deterioration of our revenues in any of our business segments;

• changes in regulatory and working capital requirements; and

• an increase in our expenses.

Principal factors that could affect our ability to obtain cash from external sources include:

• operating covenants contained in our credit facilities that limit our total borrowing capacity;

• increases in interest rates under our credit facilities;

• credit rating downgrades, which could limit our access to additional debt;

• a decrease in the market price of our common stock; and

• volatility or disruption in the public debt and equity markets.

The following sections discuss the effects of changes in our financial assets, debt obligations, clearing and broker-dealer net capital requirements, and cash flows on our liquidity and capital resources.

Financial Assets

The following table summarizes our financial assets:

	June 30, 2018		December 31, 2017
	(in millions)
Cash and cash equivalents	$	322	$	377
Restricted cash	34		22
Financial investments, at fair value	313		235
Total financial assets	$	669	$	634

Cash and Cash Equivalents and Restricted Cash

Cash and cash equivalents includes all non-restricted cash in banks and highly liquid investments with original maturities of 90 days or less at the time of purchase. The balance retained in cash and cash equivalents is a function of anticipated or possible short-term cash needs, prevailing interest rates, our investment policy, and alternative investment choices. As of June 30, 2018, our cash and cash equivalents of $322 million were primarily invested in bank deposits, money market funds and commercial paper. In the long-term, we may use both internally generated funds and external sources to satisfy our debt obligations and other long-term liabilities. Cash and cash equivalents as of June 30, 2018decreased$55 million from December 31, 2017, primarily due to:

• repurchases of our common stock;

• repayments made on commercial paper, net;

• cash dividends paid on our common stock;

• repayments of long-term debt;

50

• net purchases of financial investments;

• purchases of property and equipment; and

• payments related to employee shares withheld for taxes, partially offset by;

• net cash provided by operating activities; and

• proceeds from divestiture of businesses, net.

See “Cash Flow Analysis” below for further discussion.

As of June 30, 2018 and December 31, 2017, restricted cash is restricted from withdrawal due to a contractual or regulatory requirement or is not available for general use. Restricted cash was $34 million as of June 30, 2018 and $22 million as of December 31, 2017, an increase of $12 million. The increase relates to an increase in regulatory capital requirements. Restricted cash is classified as restricted cash in the Condensed Consolidated Balance Sheets.

Repatriation of Cash

Our cash and cash equivalents held outside of the U.S. in various foreign subsidiaries totaled $98 million as of June 30, 2018 and $138 million as of December 31, 2017. The remaining balance held in the U.S. totaled $224 million as of June 30, 2018 and $239 million as of December 31, 2017.

Unremitted earnings of subsidiaries outside of the U.S. are used to finance our international operations and are generally considered to be indefinitely reinvested. It is not our current intent to change this position. However, the majority of cash held outside the U.S. is available for repatriation, but under current law in certain jurisdictions, could subject us to additional income taxes, less applicable foreign tax credits.

Share Repurchase Program

See “Share Repurchase Program,” of Note 12, “Nasdaq Stockholders’ Equity,” to the condensed consolidated financial statements for further discussion of our share repurchase program.

Cash Dividends on Common Stock

The following table shows quarterly cash dividends paid per common share on our outstanding common stock:

	2018		2017
First quarter	$	0.82	$	0.32
Second quarter	—		0.38
Total	$	0.82	$	0.70

See “Cash Dividends on Common Stock,” of Note 12, “Nasdaq Stockholders’ Equity,” to the condensed consolidated financial statements for further discussion of the dividends.

Financial Investments, at Fair Value

Our financial investments, at fair value totaled $313 million as of June 30, 2018 and $235 million as of December 31, 2017 and are primarily comprised of trading securities, mainly highly rated European government debt securities. Of these securities, $153 million as of June 30, 2018 and $160 million as of December 31, 2017 are assets utilized to meet regulatory capital requirements, primarily for our clearing operations at Nasdaq Clearing. See Note 7, “Investments,” to the condensed consolidated financial statements for further discussion of our trading investment securities.

In addition to the $1 billion revolving credit commitment and $400 million term loan facility, we also have other credit facilities related to our Nasdaq Clearing operations in order to provide further liquidity. Other credit facilities, which are available in multiple currencies, totaled $218 million as of June 30, 2018 and $187 million as of December 31, 2017, in available liquidity, none of which was utilized.

As of June 30, 2018, we were in compliance with the covenants of all of our debt obligations.

See Note 9, “Debt Obligations,” to the condensed consolidated financial statements for further discussion of our debt obligations.

Clearing and Broker-Dealer Net Capital Requirements

Clearing Operations Regulatory Capital Requirements

We are required to maintain minimum levels of regulatory capital for the clearing operations of Nasdaq Clearing. The level of regulatory capital required to be maintained is dependent upon many factors, including market conditions and creditworthiness of the counterparty. As of June 30, 2018, our required regulatory capital of $153 million is primarily comprised of highly rated European government debt securities that are included in financial investments, at fair value in the Condensed Consolidated Balance Sheets.

Broker-Dealer Net Capital Requirements

Our broker-dealer subsidiaries, Nasdaq Execution Services, Execution Access, NPM Securities, SMTX, and Nasdaq Capital Markets Advisory are subject to regulatory requirements intended to ensure their general financial soundness and liquidity. These requirements obligate these subsidiaries to comply with minimum net capital requirements. The following

table summarizes the net capital requirements for our broker-dealer subsidiaries as of June 30, 2018:

Broker-Dealer Subsidiaries	Total Net Capital		Required Minimum Net Capital		Excess Capital
	(in millions)
Nasdaq Execution Services	$	16.8	$	0.3	$	16.5
Execution Access	34.0		0.3		33.7
NPM Securities	0.7		0.3		0.4
SMTX	2.6		0.3		2.3
Nasdaq Capital Markets Advisory	0.5		0.3		0.2

Net Cash Provided by Operating Activities

Net cash provided by operating activities increased$140 million for the six months ended June 30, 2018 compared with the same period in 2017. The increase was primarily due to a decrease in estimated tax payments resulting from the utilization of 2017 U.S. overpayments against 2018 estimated tax payments, higher Section 31 fees collected, lower compensation payments in the first six months of 2018 compared to the same period in 2017 primarily due to prior year performance and severance payments made in the first quarter 2017 related to our 2016 acquisitions, and cash flows related to our acquisition of eVestment in the fourth quarter of 2017.

Contractual Obligations and Contingent Commitments

Nasdaq has contractual obligations to make future payments under debt obligations by contract maturity, minimum rental commitments under non-cancelable operating leases, net and other obligations. The following table shows these contractual obligations as of June 30, 2018:

	Payments Due by Period
Contractual Obligations	Total		Less than 1 year		1-3 years		3-5 years		More than 5 years
	(in millions)
Debt obligations by contract maturity(1)	$	4,389	$	887	$	1,596	$	807	$	1,099

Total	$	5,093	$	983	$	1,748	$	903	$	1,459

____________

⁽¹⁾  Our debt obligations include both principal and interest obligations. As of June 30, 2018, an interest rate of 3.99% was used to compute the amount of the contractual obligations for interest on the 2016 Credit Facility and 2.86% was used to compute the amount of the contractual obligations for interest on the 2019 Notes. All other debt obligations were primarily calculated on a 360-day basis at the contractual fixed rate multiplied by the aggregate principal amount as of June 30, 2018. See Note 9, “Debt Obligations,” to the condensed consolidated financial statements for further discussion.

⁽²⁾  We lease some of our office space under non-cancelable operating leases with third parties and sublease office space to third parties. Some of our leases contain renewal options and escalation clauses based on increases in property taxes and building operating costs.

⁽³⁾  Purchase obligations primarily represent minimum outstanding obligations due under software license agreements.

⁽⁴⁾  Other obligations primarily consist of potential future escrow agreement payments related to prior acquisitions.

53

In addition, we have a 40.0% ownership in OCC. Under the OCC's capital plan, the OCC shareholders have committed to contribute up to $200 million in equity capital if certain

capital thresholds are breached, including up to $80 million to be contributed by Nasdaq. See “Equity Method Investments,” of Note 7, “Investments,” to the condensed consolidated financial statements for further discussion of our

equity method investment in OCC.

Non-Cash Contingent Consideration

As part of the purchase price consideration of a prior acquisition, we have agreed to future annual issuances of 992,247 shares of Nasdaq common stock which approximated certain tax benefits associated with the transaction. Such contingent future issuances of Nasdaq common stock will be paid ratably through 2027 if Nasdaq’s total gross revenues equal or exceed $25 million in each such year. The contingent future issuances of Nasdaq common stock are subject to anti-dilution protections and acceleration upon certain events.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Market risk represents the potential for losses that may result from changes in the market value of a financial instrument due to changes in market conditions. As a result of our operating, investing and financing activities, we are exposed to market risks such as interest rate risk and foreign currency exchange rate risk. We are also exposed to credit risk as a result of our normal business activities.

We have implemented policies and procedures to measure, manage, monitor and report risk exposures, which are reviewed regularly by management and the board of directors. We identify risk exposures and monitor and manage such risks on a daily basis.

We perform sensitivity analyses to determine the effects of market risk exposures. We may use derivative instruments solely to hedge financial risks related to our financial positions or risks that are incurred during the normal course of business. We do not use derivative instruments for speculative purposes.

Interest Rate Risk

We are subject to the risk of fluctuating interest rates in the normal course of business. Our exposure to market risk for changes in interest rates relates primarily to our financial investments and debt obligations which are discussed below.

Financial Investments

As of June 30, 2018, our investment portfolio was primarily comprised of trading securities, mainly highly rated European government debt securities, which pay a fixed rate of interest. These securities are subject to interest rate risk and will decrease in value if market interest rates increase. If market interest rates were to increase immediately and uniformly by 100 basis points from levels as of June 30, 2018, the fair value of this portfolio would have declined by $4 million.

Debt Obligations

As of June 30, 2018, substantially all of our debt obligations are fixed-rate obligations. While changes in interest rates will have no impact on the interest we pay on fixed-rate obligations, we are exposed to changes in interest rates as a result of the issuance of our 2019 Notes, borrowings under our 2017 Credit Facility and 2016 Credit Facility, and amounts outstanding from the sale of commercial paper under our commercial paper program, all of which have variable interest rates. As of June 30, 2018, we had principal amounts outstanding of $500 million on the 2019 Notes, $100 million under the 2016 Credit Facility, and $270 million of commercial paper. A hypothetical 100 basis points increase in interest rates on our outstanding 2019 Notes, the 2016 Credit Facility and our outstanding commercial paper would increase interest expense by approximately $9 million based on borrowings as of June 30, 2018.

54

Foreign Currency Exchange Rate Risk

As a leading global exchange group, we are subject to foreign currency transaction risk. Our primary exposure to foreign currency denominated revenues less transaction-based expenses and operating income for the three and six months ended June 30, 2018 is presented in the following table:

	Euro			Swedish Krona			Other Foreign Currencies			U.S. Dollar			Total

N/A Not applicable.

Our investments in foreign subsidiaries are exposed to volatility in currency exchange rates through translation of the foreign subsidiaries’ net assets or equity to U.S. dollars. Substantially all of our foreign subsidiaries operate in functional currencies other than the U.S. dollar. Fluctuations in currency exchange rates may create volatility in our results of operations as we are required to translate the balance sheets and operational results of these foreign currency denominated subsidiaries into U.S. dollars for consolidated reporting. The translation of foreign subsidiaries’ non-U.S. dollar balance sheets into U.S. dollars for consolidated reporting results in a cumulative translation adjustment which is recorded in accumulated other comprehensive loss within stockholders’ equity in the Condensed Consolidated Balance Sheets.

Our primary exposure to net assets in foreign currencies as of June 30, 2018 is presented in the following table:

	Net Assets		Impact of a 10% Adverse Currency Fluctuation
	(in millions)
Swedish Krona(1)	$	3,267	$	(327	)

Credit Risk

Credit risk is the potential loss due to the default or deterioration in credit quality of customers or counterparties. We are exposed to credit risk from third parties, including customers, counterparties and clearing agents. These parties may default on their obligations to us due to bankruptcy, lack of liquidity, operational failure or other reasons. We limit our exposure to credit risk by rigorously evaluating the counterparties with which we make investments and execute agreements. The financial investment portfolio objective is to invest in securities to preserve principal while maximizing yields, without significantly increasing risk. Credit risk associated with investments is minimized substantially by ensuring that these financial assets are placed with governments which have investment grade ratings, well-capitalized financial institutions and other creditworthy counterparties.

Our subsidiary, Nasdaq Execution Services, may be exposed to credit risk, due to the default of trading counterparties, in connection with the routing services it provides for our trading customers. System trades in cash equities routed to other market centers for members of our cash equity exchanges are routed by Nasdaq Execution Services for clearing to the NSCC. In this function, Nasdaq Execution Services is to be neutral by the end of the trading day, but may be exposed to intraday risk if a trade extends beyond the trading day and into the next day, thereby leaving Nasdaq Execution Services susceptible to counterparty risk in the period between accepting the trade and routing it to the clearinghouse. In this interim period, Nasdaq Execution Services is not novating like a clearing broker but instead is subject to the short-term risk of counterparty failure before the clearinghouse enters the transaction. Once the clearinghouse officially accepts the trade for novation, Nasdaq Execution Services is legally removed from trade execution risk. However, Nasdaq has membership obligations to NSCC independent of Nasdaq Execution Services’ arrangements.

Pursuant to the rules of the NSCC and Nasdaq Execution Services’ clearing agreement, Nasdaq Execution Services is liable for any losses incurred due to a counterparty or a clearing agent’s failure to satisfy its contractual obligations, either by making payment or delivering securities. Adverse movements in the prices of securities that are subject to these transactions can increase our credit risk. However, we believe that the risk of material loss is limited, as Nasdaq Execution Services’ customers are not permitted to trade on margin and NSCC rules limit counterparty risk on self-cleared transactions by establishing credit limits and capital deposit requirements for all brokers that clear with NSCC. Historically, Nasdaq Execution Services has never incurred a liability due to a customer’s failure to satisfy its contractual obligations as counterparty to a system trade. Credit difficulties or insolvency, or the perceived possibility of credit difficulties or insolvency, of one or more larger or visible market participants could also result in market-wide credit difficulties or other market disruptions.

Execution Access is an introducing broker which operates the trading platform for our Fixed Income business to trade in U.S. Treasury securities. Execution Access has a clearing arrangement with Cantor Fitzgerald. As of June 30, 2018, we have contributed $19 million of clearing deposits to Cantor Fitzgerald in connection with this clearing arrangement. This clearing agreement ended on July 31, 2018, and has been replaced by a clearing agreement with ICBC, where all trades have cleared since June 25, 2018. As a result, we also have contributed $15 million of clearing deposits to ICBC. These deposits are recorded in other current assets in our Condensed Consolidated Balance Sheets. In July 2018, the majority of the clearing deposit of $19 million which was contributed to Cantor Fitzgerald has been reimbursed. Some of the trading activity in Execution Access is cleared by ICBC through the Fixed Income Clearing Corporation, with ICBC acting as agent. Execution Access assumes the counterparty risk of clients that do not clear through the Fixed Income Clearing Corporation. Counterparty risk of clients exists for Execution Access between the trade date and settlement date of the individual transactions, which is at least one business day (or more, if specified by the U.S. Treasury issuance calendar). Counterparties that do not clear through the Fixed Income Clearing Corporation are subject to a credit due diligence process and may be required to post collateral, provide principal letters, or provide other forms of credit enhancement to Execution Access for the purpose of mitigating counterparty risk. Daily position trading limits are also enforced for such counterparties.

We are exposed to credit risk through our clearing operations with Nasdaq Clearing. See Note 15, “Clearing Operations,” to the condensed consolidated financial statements for further discussion.

We also have credit risk related to transaction and subscription-based revenues that are billed to customers on a monthly or quarterly basis, in arrears. Our potential exposure to credit losses on these transactions is represented by the receivable balances in our Condensed Consolidated Balance Sheets. On an ongoing basis, we review and evaluate changes in the status of our counterparties’ creditworthiness. Credit losses such as those described above could adversely affect our consolidated financial position and results of operations.

Item 4. Controls andProcedures.

(a) Disclosure controls and procedures. Nasdaq’s management, with the participation of Nasdaq’s President and Chief Executive Officer, and Executive Vice President, Corporate Strategy and Chief Financial Officer, has evaluated the effectiveness of Nasdaq’s disclosure controls and procedures (as defined in Rule 13a-15(e) and Rule 15d-15(e) under the Exchange Act) as of the end of the period covered by this report. Based upon that evaluation, Nasdaq’s President and Chief Executive Officer and Executive Vice President, Corporate Strategy and Chief Financial Officer, have concluded that, as of the end of such period, Nasdaq’s disclosure controls and procedures are effective.

(b) Internal control over financial reporting. There have been no changes in Nasdaq’s internal control over financial reporting (as defined in Rule 13a-15(f) and Rule 15d-15(f) under the Exchange Act) that occurred during the quarter ended June 30, 2018 that have materially affected, or are reasonably likely to

56

materially affect, Nasdaq’s internal control over financial reporting.

Item 5. OtherInformation.

On July 29, 2018, the management compensation committee of the board of directors of Nasdaq, Inc. (“Nasdaq”) approved, and Nasdaq subsequently entered into, an employment agreement with Edward S. Knight, Nasdaq’s Executive Vice President and Global Chief Legal and Policy Officer. In addition, Nasdaq and Mr. Knight entered into a Continuing Obligations Agreement, which is an exhibit to the employment agreement.

57

The term of the employment agreement is July 29, 2018 to December 31, 2020. The agreement provides that Mr. Knight will report directly to the Chief Executive Officer and continue to serve as Executive Vice President and Global Chief Legal and Policy Officer. During the term, Mr. Knight and Nasdaq’s Chief Executive Officer have the option to mutually agree upon a date for Mr. Knight to transition to serve as a Vice Chairman of Nasdaq, and his compensation as Vice Chairman will be determined at the time of the transition. In his current role, Mr. Knight will receive:

• an annual base salary of no less than $550,000; and

• annual incentive compensation that is targeted at not less than $825,000 based on the achievement of one or more performance goals established for such year by the Chief Executive Officer and the management compensation committee of Nasdaq’s board of directors (the “Target Bonus”).

Mr. Knight also shall be eligible for an annual target equity compensation award determined annually, in accordance with the terms of the Nasdaq Equity Incentive Plan (the “Equity Plan”).

To the extent Mr. Knight acts in a non-legal capacity during the last 12 months of his employment, the agreement prohibits him from rendering services to a competing entity for a period of two years following the date of termination of employment. To receive certain termination payments and benefits under the new employment agreement, Mr. Knight must execute a general release of claims against Nasdaq. In addition, these termination payments and benefits are generally subject to discontinuation in the event Mr. Knight breaches the restrictive covenants in either the employment agreement or the Continuing Obligations Agreement.

The agreement sets forth the payments that Mr. Knight will receive under various termination scenarios, as discussed further below. Such payments will be in addition to payments for unpaid base salary through the date of termination, accrued but unpaid vacation through the date of termination and any earned but unpaid incentive compensation for the calendar year prior to the date of termination (the “Base Obligations”). To the extent not addressed below, the treatment of Mr. Knight’s equity awards under the various termination scenarios will be addressed in the Equity Plan and the underlying equity award agreements.

Termination Without Cause or by the Executive For Good Reason or with Notice of Retirement. If Mr. Knight’s employment is terminated by Nasdaq without cause, or by Mr. Knight for good reason or with 60 days’ notice of retirement after February 28, 2019, he will be entitled to the following payments and benefits:

• any pro rata Target Bonus with respect to the calendar year in which the termination occurs;

• continued vesting of all unvested equity;

• a taxable monthly cash payment equal to the Consolidated Omnibus Budget Reconciliation Act (“COBRA”) premium for the highest level of coverage available under Nasdaq’s group health plans, reduced by the monthly amount that Mr. Knight would pay for such coverage if he was an active employee, until the earlier of 18 months or the date Mr. Knight is eligible for coverage under the health care plans of a subsequent employer; and

• 24 months of financial and tax services and executive physical exams.

Termination Due To Permanent Disability or Death. If Mr. Knight’s employment is terminated due to permanent disability or death, he, or his estate, will be entitled to the following payments and benefits:

• a cash payment equal to any pro rata Target Bonus with respect to the calendar year in which the termination occurs; and

• accelerated vesting of all unvested equity awarded as of the effective date of the employment agreement.

“Double Trigger” Termination In Connection With A Change in Control Without Cause or For Good Reason. If Mr. Knight’s employment is “double trigger” terminated within two years after a change in control, without cause by Nasdaq or for good reason by Mr. Knight, he will be entitled to the following payments and benefits:

• a cash payment equal to the sum of: (i) his base salary for the remaining term of the agreement and (ii) the target amount of his annual incentive compensation for the fiscal years in the remaining term of the agreement;

• a taxable monthly cash payment equal to the COBRA premium for the highest level of coverage available under Nasdaq’s group health plans, reduced by the monthly amount that Mr. Knight would pay for such coverage if he was an active employee, until the earlier of 24 months or the date Mr. Knight is eligible for coverage under the health care plans of a subsequent employer; and

• continued life insurance and accidental death and dismemberment insurance benefits for the same period as the continued health coverage payments.

Under a “best net provision,” if any amounts payable to Mr. Knight under this scenario would be characterized as excess parachute payments and due to that characterization, Mr. Knight would be subject to an excise tax under Section 4999 of the Internal Revenue Code of 1986, as amended, the amounts will be reduced to an amount so that none of the amounts payable constitute excess

58

parachute payments if this would result, after taking into account the applicable federal, state and local income taxes and the excise tax imposed by Section 4999, in Mr. Knight’s receipt on an after-tax basis of the greatest amount of termination and other benefits.

Termination For Cause or by the Executive under Certain Circumstances. If Mr. Knight’s employment is terminated by Nasdaq for cause, or by Mr. Knight without good reason prior to March 31, 2019 or for any reason without 60 days’ notice after February 28, 2019, he will have no further rights to any compensation other than the Base Obligations.

Board Compensation Policy

Amended and Restated on April 24, 2018

Purpose & Statement Of Policy	QUESTIONS? Please contact the Stock Plan Administrator if at any time you have questions about the equity element of the policy. Please contact the Office of the Corporate Secretary with questions about the cash element of the policy.
Annual Non-Employee Director (“Director”) compensation consists of the following elements, each of which is discussed further below: (i) annual retainer, (ii) annual equity award, (iii) annual committee chair fees and (iv) annual committee member fees.
Director compensation will be based on a compensation year in connection with the annual meeting of stockholders (the “Annual Meeting”). This enables Directors to receive equity immediately following election and appointment to the Board at the Annual Meeting.
Applicability & Scope
This Policy is applicable to all non-employee Directors of Nasdaq, Inc.

Annual Retainer

• Annual Director Retainer compensation is equal to a total value of $75,000 for each Director, other than the Chairman of the Board.

• The Lead Independent Director, if any, will receive the Annual Director Retainer plus an additional Lead Independent Director Retainer of $75,000.

• The Chairman of the Board will receive Annual Board Chairman Retainer compensation equal to a total value of $240,000.

• Annual Retainer compensation will be delivered in the form of equity; however, Directors may annually elect to receive Retainer compensation in cash or equity. Each Director will have the opportunity to make this election during the thirty (30) day period preceding the Annual Meeting. If the Director declines to make an election, the entire Annual Retainer will be paid in equity.

• Equity will be issued as Restricted Stock Units to each eligible director automatically on the date of the Annual Meeting immediately following the Director’s election and appointment by the Board. The equity portion

selected will be paid in accordance with the “Policies and Procedures Relating to Equity Grants” below.

• If cash is selected, the cash portion will be paid semi- annually in arrears, in equal installments, no later than the fifteenth day of the third month following the end of the semi-annual period; provided, however, that a Director will have a right to receive a cash payment for any given period only if that person serves as a Director during all or a portion of that period, with the cash payment for the period being prorated in the case of a person who serves as a Director during only a portion of a period (other than on account of death or disability).

• A Director appointed after the annual shareholders meeting will be eligible to receive a prorated share of the Annual Retainer compensation. Such a Director may elect to receive the Annual Retainer compensation in cash or equity. Equity will be paid retroactively on the date of the next Annual Meeting. Any cash portion will be paid semi-annually in arrears.

* * *

1.Rights of the Participant with Respect to the Restricted Stock Units.

(a)Prior to vesting of the RSUs pursuant to Section 2, (i) the Participant shall not be treated as a shareholder as to Shares issuable to the Participant with respect to such RSUs, and shall only have a contractual right to receive such Shares following such vesting, unsecured by any assets of the Company or its Subsidiaries; (ii) the Participant shall not be permitted to vote the RSUs or the Shares issuable with respect to such RSUs; and (iii) the Participant’s right to receive such Shares following vesting of the RSUs shall be subject to the adjustment provisions set forth in Section 13 of the Plan. The RSUs shall be subject to all of the restrictions hereinafter set forth.

(b)At the sole discretion of the Committee, the Participant shall be permitted to receive cash payments equal to the dividends and distributions paid on Shares (other than dividends or distributions of securities of the Company which may be issued with respect to Shares by virtue of any stock split, combination, stock dividend or recapitalization) to the same extent as if each RSU was a Share, and those Shares were not subject to the restrictions imposed by this Award Certificate and the Plan; provided, however, that no dividends or distributions shall be payable to or for the benefit of the Participant with respect to record dates for such dividends or distributions occurring on or after the date, if any, on which the Participant has forfeited the RSUs.

2.Vesting.

(a)Except as otherwise provided under this Award Certificate, the RSUs shall vest in accordance with the following vesting schedule: [VESTING SCHEDULE WITH FINAL VESTING DATE] (the “Final Vesting Date”); provided, in each case, that the Participant remains in continuous employment with the Company or any of its Subsidiaries until such date(s).

(b)If, prior to the Final Vesting Date of the RSUs under paragraph (a) above the Participant has a Separation from Service (as defined in the Plan) with the Company or any of its Subsidiaries for any reason (voluntary or involuntary), then such non-vested RSUs shall be immediately and irrevocably forfeited, except as otherwise provided in Section 8(e)(ii) of the Plan (Separation from Service by reason of death or Retirement) or Section 12 of the Plan (Separation from Service following a Change in Control). Notwithstanding anything to the contrary in the Plan or this Award Certificate, and for purposes of clarity, any Separation from Service shall be effective as of the date the Participant’s active employment ends and shall not be extended by any statutory or common law notice period.

(c)If, prior to the vesting of the RSUs under paragraph (a) above the Participant is determined by the insurance carrier under the Company’s then-current long-term disability plan to be entitled to receive benefits under such plan, and, by reason of such Disability, is deemed to have a Separation from Service (within the meaning of the Plan), then an amount of unvested RSUs shall vest as described in Section 8(e)(iii) of the Plan.

The Company may make delivery of Shares in settlement of RSUs by either (A) delivering certificates representing such Shares to the Participant, registered in the name of the Participant, or (B) by depositing such Shares into a stock brokerage account maintained for the Participant. The Company will not deliver any fractional shares of Common Stock but will instead round down to the next full number the amount of shares of Common Stock to be delivered.

4.No Right to Continued Employment. Neither the Plan nor this Award Certificate shall confer on the Participant any right to be retained, in any position, as an employee, consultant or director of the Company, and nothing in this Award Certificate or the Plan shall be construed to limit the discretion of the Company (or subsidiary of the Company that employs the Participant) to terminate the Participant’s employment at any time, with or without cause.

5.Transferability.

(a)The RSUs are not transferable and may not be sold, assigned, transferred, disposed of, pledged or otherwise encumbered by the Participant, other than by will or the laws of descent and distribution.

(b)Subject to Section 5(a) hereof, in order to comply with any applicable securities laws, the Shares issued to the Participant with respect to vested RSUs may only be sold by the Participant following registration of such Shares under the U.S. Securities Act of 1933, as amended, or pursuant to an exemption therefrom.

(c)     Following settlement and issuance of Shares, in the event the Company permits Participant to arrange for sale of Shares through a broker or another designated agent of the Company, Participant acknowledges and agrees that the Company may block any such sale and/or cancel any order to sell placed by the Participant, in each case if the Participant is not then permitted under the Company’s insider trading policy to engage in transactions with respect to securities of the Company. If the Committee determines that the ability of the Participant to sell or transfer shares of Common Stock is restricted, then the Company may notify the Participant in accordance with Section 14 of this Award Certificate.

The Company may make delivery of Shares in settlement of Restricted Stock Units by either (A) delivering certificates representing such Shares to the Director, registered in the name of the Director, or (B) by depositing such Shares into a stock brokerage account maintained for the Director. The Company will not deliver any fractional shares of Common Stock but will instead round down to the next full number the amount of shares of Common Stock to be delivered.

Notwithstanding anything in this Section 4 to the contrary, the Company may, in its sole discretion, settle the RSUs in the form of a cash payment to the extent settlement in Shares is prohibited under local law, or would require the Director, the Company and/or a Subsidiary to obtain the approval of any governmental and/or regulatory body in the Director’s country of residence (and country of employment, if different). Alternatively, the Company may, in its sole discretion, settle the RSUs in the form of Shares but require the Director to immediately sell such Shares (in which case, the Award Certificate shall give the Company the authority to issue sales instructions on behalf of the Director).

5.No Right to Continued Service. Neither the Plan nor this Award Certificate shall confer on the Director any right to be retained, in any position, as an employee, consultant or director of the Company.

6.Transferability.

(a)At any time prior to becoming vested, the Restricted Stock Units are not transferable and may not be sold, assigned, transferred, disposed of, pledged or otherwise encumbered by the Director, other than by will or the laws of descent and distribution. Upon such transfer (by will or the laws of descent and distribution), such transferee in interest shall take the rights granted herein subject to all the terms and conditions hereof.

(b)Subject to Section 6(a) hereof, in order to comply with any applicable securities laws, the Shares issued to the Director with respect to vested Restricted Stock Units may only be sold by the Director following registration of such Shares under the U.S. Securities Act of 1933, as amended, or pursuant to an exemption therefrom.

-3-

(c)Following settlement and issuance of Shares, in the event the Company permits the Director to arrange for sale of Shares through a broker or another designated agent of the Company, Director acknowledges and agrees that the Company may block any such sale and/or cancel any order to sell placed by the Director, in each case if the Director is not then permitted under the Company’s insider trading policy to engage in transactions with respect to securities of the Company. If the Committee determines that the ability of the Director to sell or transfer Shares is restricted, then the Company may notify the Director in accordance with Section 13 of this Award Certificate. The Director may only sell such Shares in compliance with such notification from the Company.

7.Withholding.

(a)In order to comply with all applicable federal, state and local tax laws or regulations, the Company may take such actions as it deems appropriate to ensure that all applicable federal, state and local payroll, withholding, income or other taxes are withheld or collected from the Director.

(b)In accordance with the terms of the Plan, and such rules as may be adopted by the Committee under the Plan, the Director may elect to satisfy the Director’s federal, state and local tax withholding obligations arising from the receipt of, the vesting of or the lapse of restrictions relating to, the RSUs, by (i) delivering cash, check or money order payable to the Company, (ii) delivering to the Company other Common Stock, (iii) having the Company withhold a portion of the shares of Common Stock otherwise to be delivered having a Fair Market Value sufficient to satisfy the statutory withholding required with respect thereto to the extent permitted by the Company; or (iv) having the Company withhold any amounts necessary to pay the statutory withholding required from the Director’s salary or other amounts payable to the Director. The Company will not deliver any fractional shares of Common Stock but will instead round down to the next full number the amount of shares of Common Stock to be delivered. The Director’s election must be made on or before the date that any such withholding obligation with respect to the RSUs arises. If the Director fails to timely make such an election, the Company shall have the right to withhold a portion of the shares of Common Stock otherwise to be delivered having a Fair Market Value equal to the statutory amount of withholding with respect to applicable taxes, as determined by the Company in its sole discretion. The net settlement of the shares underlying the vested RSUs and the delivery of shares of Common Stock previously owned are hereby specifically authorized alternatives for the satisfaction of the foregoing withholding obligation. To the extent necessary to meet any obligation to withhold Federal Insurance Contributions Act taxes before delivery of the Shares, the Company is authorized to deduct those taxes from other current wages.

8.Governing Law. This Award Certificate shall be governed by and construed in accordance with the laws of the State of Delaware, without regard to the conflicts of law provisions thereof.

9.Amendments. The Company, acting by means of the Committee, has the right, as set forth in the Plan, to amend, alter, suspend, discontinue or cancel this Award, prospectively or retroactively; provided however, that no such amendment, alteration, suspension, discontinuance or cancelation of the RSUs will adversely affect the Director’s material rights under this Award Certificate without the Director’s consent. The Company has the authority to amend this Award

-4-

Certificate, consistent with the foregoing, without the Director’s written agreement, except as set forth in this Section 9.

In the event that the Company is reorganized or liquidated, or if all or substantially all of its assets are sold, or if the Company is merged or consolidated with another corporation or entity (or in the event the Company consummates a written agreement to accomplish any of the foregoing), the Committee may, in its sole discretion and upon at least 10 days advance notice to the Director, cancel any outstanding RSUs and cause the Director to be paid (in cash or in stock, or any combination thereof) the value of such RSUs based upon the price per share of Common Stock received or to be received in the transaction.

10.Administration. This Award Certificate shall at all times be subject to the terms and conditions of the Plan. Capitalized terms not defined in this Award Certificate shall have the meanings set forth in the Plan.

Any such amendments shall be made in a manner that preserves to the maximum extent possible the intended benefits to Director. This paragraph does not create an obligation on the part of Company to modify this Award Certificate and does not guarantee that the amounts or benefits owed under this Award Certificate will not be subject to interest and penalties under Code Section 409A. For purposes of applying the provisions of Code Section 409A, to the extent applicable, each group of Restricted Stock Units that would vest in accordance with Section 2 shall be treated as a separate payment.

(c)While the Company intends that this Award Certificate and the RSUs granted hereunder comply with or be exempt from the requirements of Code Section 409A and any related regulations or other guidance promulgated thereunder, neither the Company or the

Committee nor any of their respective affiliates shall be liable to any person for the tax consequences of any failure to comply with the requirements of Code Section 409A or any other tax consequences relating to this Award.

Exhibit 10.4

NASDAQ, INC.
PERFORMANCE SHARE UNIT AGREEMENT

This PERFORMANCE SHARE UNIT AGREEMENT (this “Agreement”) between Nasdaq, Inc., a Delaware corporation (the “Company”), and NAME (the “Grantee”) memorializes the grant by the Management Compensation Committee of the Board of Directors of the Company (the “Committee”) on DATE (the “Grant Date”) of performance share units (the “PSUs”) to the Grantee on the terms and conditions set out below.

RECITALS:

The Company has adopted the Nasdaq, Inc. Equity Incentive Plan (the “Plan”), which Plan is incorporated herein by reference and made a part of this Agreement. Capitalized terms not otherwise defined herein shall have the meaning ascribed to them in the Plan. The Plan in relevant part provides for the issuance of stock-based awards that are subject to the attainment of performance goals as established by the Committee.

The Committee has determined that it is in the best interests of the Company and its shareholders to grant the PSUs provided for herein to the Grantee pursuant to the Plan and under the terms set forth herein as an increased incentive for the Grantee to contribute to the Company’s future success and prosperity.

Capitalized terms not otherwise defined herein shall have the meaning ascribed to them in the Plan.

NOW, THEREFORE, in consideration of the mutual covenants hereinafter set forth, the parties hereto agree as follows:

1.Grant of Performance-Based Award. The Company hereby grants to the Grantee TARGET PSUs, which PSUs shall entitle the Grantee to receive up to MAX PAYOUT Shares (or a lesser number of Shares, or no Shares whatsoever), subject to the terms and conditions set forth in this Agreement and the Plan. (A complete copy of the Plan, as in effect on the Grant Date, is available to the Grantee upon request.) Shares corresponding to the PSUs granted herein are in all events to be delivered to the Grantee only after the Grantee has become vested in the PSUs pursuant to Section 4 below.

2.Performance Period. For purposes of this Agreement, the term “Performance Period” shall be the period commencing on January 1, 2018 and ending on December 31, 2018.

3.Performance Goal.

(a)Subject to the following sentence, the Performance Goal is set out in Appendix A hereto, which Appendix A is incorporated by reference herein and made a part hereof. Notwithstanding the foregoing, the provisions of Section 13 or any other provision of this Agreement to the contrary, the Committee reserves the right to unilaterally change or otherwise modify the Performance Goal in any manner whatsoever (including substituting a new Performance Goal), but only to the extent that the Committee has first determined that the

A-1

exercise of such discretion would not cause the PSUs to fail to qualify as “performance-based compensation” under Section 162(m) of the Code. If the Committee exercises such discretionary authority to any extent, the Committee shall provide the Grantee with a new Appendix A in substitution for the Appendix A attached hereto, and such new Appendix A and the Performance Goal set out therein (rather than the Appendix A attached hereto and the Performance Goal set out therein) shall in all events apply for all purposes of this Agreement.

(b)Depending upon the extent, if any, to which the Performance Goal has been achieved, and subject to compliance with the requirements of Section 4, each PSU shall entitle the Grantee to receive, at such time as is determined in accordance with the provisions of Section 5, between 0 and 1.5 Shares for each PSU. The Committee shall, as soon as practicable following the last day of the Performance Period, certify (i) the extent, if any, to which, in accordance with Appendix A, the Performance Goal has been achieved with respect to the Performance Period and (ii) the number of whole and/or partial Shares, if any, which, subject to compliance with the vesting requirements of Section 4, the Grantee shall be entitled to receive with respect to each PSU (with such number of whole and/or partial Shares being hereafter referred to as the “Share Delivery Factor”). Such certification shall be final, conclusive and binding on the Grantee, and on all other persons, to the maximum extent permitted by law.

4.Vesting.

(a)The PSUs are subject to forfeiture to the Company until they become non-forfeitable in accordance with this Section 4. Except as provided in the following sentence, (i) the risk of forfeiture will lapse on the first one-third of the PSUs, and such PSUs shall thereupon become vested, only if the Grantee remains employed by the Company through and on December 31, 2019;(ii) the risk of forfeiture will lapse on the second one-third of the PSUs, and such PSUs shall thereupon become vested, only if the Grantee remains employed by the Company through and on December 31, 2020; and (iii) the risk of forfeiture will lapse on the remaining PSUs, and such PSUs shall thereupon become vested, only if the Grantee remains employed by the Company through and on December 31, 2021 (collectively with December 31, 2019 and December 31, 2020, each a “Vest Date”). Notwithstanding the foregoing, if the Grantee’s employment with the Company terminates by reason of death prior to December 31, 2021, the risk of forfeiture shall lapse on all PSUs, and all unvested PSUs shall thereupon become vested on the date of death (or, if later, on the date, following the end of the Performance Period on which the Committee determines whether, and to what extent the PSUs are earned in accordance with Section 3(b) of this Agreement).

(b)In the event that (i) the Company terminates the Grantee’s employment with the Company for any reason prior to a Vest Dateor (ii) the Grantee terminates employment with the Company for any reason (other than death) prior to such date, all unvested PSUs shall be cancelled and forfeited, effective as of the Grantee’s separation from service. Notwithstanding anything to the contrary in the Plan or this Agreement, and for purposes of clarity, any separation from service shall be effective as of the date the Grantee’s active employment ends and shall not be extended by any statutory or common law notice period.

5.Delivery of Shares.As soon as practicable following the applicable Vest Date, and compliance with all applicable tax withholding as described in Section 11 hereof, but in no event later than two and one-half months after the end of the calendar year in which the Vest Date occurs, the Company shall instruct the registrar for the Company to make an entry on its books and records evidencing that the Shares underlying such vested PSUs have been duly issued as of that date; provided, however, that the Grantee may, in the alternative, elect in writing prior thereto to receive a stock certificate representing the full number of Shares acquired, which certificate may bear a restrictive legend prohibiting the transfer of such Shares for such period as may be prescribed by the Company. The Company shall not be liable to the Grantee for damages relating to any delays in issuing the certificates. The underlying Shares may be registered in the name of the Grantee’s legal representative or estate in the event of the death of the Grantee. In the event of the acceleration of the lapse of forfeiture restrictions upon the death of the Grantee as contemplated by Section 4(a) of this Agreement, this process shall occur as soon as possible following such vesting date, but in no event later than two and one-half months after the end of the calendar year in which such vesting date occurs. Notwithstanding anything in the Agreement, the Company may make delivery of Shares in settlement of PSUs by either (A) delivering certificates representing such Shares to the Grantee, registered in the name of the Grantee, or (B) by depositing such Shares into a stock brokerage account maintained for the Grantee.

6.Electronic Delivery. The Company may, in its sole discretion, decide to deliver any documents related to the PSUs or future Awards granted under the Plan by electronic means or request the Grantee’s consent to participate in the Plan by electronic means. By accepting this Award, the Grantee hereby consents and agrees to receive such documents by electronic delivery and agrees to participate in the Plan through an on-line or electronic system established and maintained by the Company or another third party designated by the Company.

7.Transferability.

(a)Except as provided below, or except to the minimal extent required by law, the PSUs are nontransferable and may not be assigned, alienated, pledged, attached, sold or otherwise transferred or encumbered by the Grantee, except by will or the laws of descent and distribution, and upon any such transfer, by will or the laws of descent and distribution (or upon such transfer required by law), the transferee shall hold such PSUs subject to all the terms and conditions that were applicable to the Grantee immediately prior to such transfer. Notwithstanding the foregoing, the Grantee may transfer any vested PSUs to members of his immediate family (defined as his spouse, children or grandchildren) or to one or more trusts for the exclusive benefit of such immediate family members or partnerships in which such immediate family members are the only partners if the transfer is approved by the Committee and the Grantee does not receive any consideration for the transfer. Any such transferred portion of the PSUs shall continue to be subject to the same terms and conditions that were applicable to such portion of the PSUs immediately prior to transfer (except that such transferred PSUs shall not be further transferable by the transferee). No transfer of a portion of the PSUs shall be effective to bind the Company unless the Company shall have been furnished with written notice thereof and a copy of such evidence as the Committee may deem necessary to establish the validity of the transfer and the acceptance by the transferee of the terms and conditions hereof.

3

(b)Upon any transfer by will or the laws of descent and distribution (or upon any such transfer required by law), such transferee shall take the PSUs and the Shares delivered in connection therewith (the “Transferee Shares”) subject to all the terms and conditions that were (or would have been) applicable to the PSUs and the Transferee Shares immediately prior to such transfer.

(c)Following settlement and issuance of Shares, in the event the Company permits the Grantee to arrange the sale of Shares through a broker or another designated agent of the Company, Grantee acknowledges and agrees that the Company may block any such sale and/or cancel any order to sell placed by the Grantee, in each case if the Grantee is not then permitted under the Company’s insider trading policy to engage in transactions with respect to securities of the Company. If the Committee determines that the ability of the Grantee to sell or transfer shares of Common Stock is restricted, then the Company may notify the Grantee in accordance with Section 18 of this Agreement.

8.Rights of Grantee. Prior to the delivery, if any, of Shares to the Grantee pursuant to the provisions of Section 5, the Grantee shall not have any rights of a shareholder of the Company, including, but not limited to, the right to receive dividend payments, on account of the PSUs.

9.Unfunded Nature of PSUs. The Company will not segregate any funds representing the potential liability arising under this Agreement. The Grantee’s rights in respect of this Agreement are those of an unsecured general creditor of the Company. The liability for any payment under this Agreement will be a liability of the Company and not a liability of any of its officers, directors or Affiliates.

10.Securities Laws. The Company may condition delivery of Shares for any vested PSUs upon the prior receipt from the Grantee of any undertakings which it may determine are required to assure that the Shares are being issued in compliance with federal and state securities laws.

11.Withholding. Regardless of any action the Company, any of its Subsidiaries and/or the Grantee's employer takes with respect to any or all income tax, social insurance, payroll tax, payment on account or other tax-related items related to the Grantee’s participation in the Plan and legally applicable to the Grantee (“Tax-Related Items”), the Grantee acknowledges that the ultimate liability for all Tax-Related Items is and remains the Grantee’s responsibility and may exceed the amount actually withheld by the Company or any of its affiliates. The Grantee further acknowledges that the Company and/or its Subsidiaries (i) make no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of the PSUs, including, but not limited to, the grant or vesting of the PSUs, the delivery of Shares, the subsequent sale of Shares acquired pursuant to such delivery and the receipt of any dividends and/or dividend equivalents; and (ii) do not commit to and are under no obligation to structure the terms of any award to reduce or eliminate the Grantee’s liability for Tax-Related Items or achieve any particular tax result. Further, if the Grantee becomes subject to tax in more than one jurisdiction between the Grant Date and the date of any relevant taxable event, the Grantee acknowledges that the Company and/or its Subsidiaries may be required to withhold or account for Tax-Related Items in more than one jurisdiction.

Prior to any relevant taxable or tax withholding event, as applicable, the Grantee will pay or make adequate arrangements satisfactory to the Company and/or its Subsidiaries to satisfy all Tax-Related Items. In this regard, the Grantee authorizes the Company and/or its Subsidiaries, or their respective agents, at their discretion, to satisfy the obligations with regard to all Tax-Related Items by one or a combination of the following:

(a)    withholding from the Grantee’s wages or other cash compensation paid to the Grantee by the Company and/or its Subsidiaries; or

(b)     withholding from proceeds of the Shares acquired following settlement either through a voluntary sale or through a mandatory sale arranged by the Company (on the Grantee’s behalf pursuant to this authorization); or

(c)     withholding in Shares to be delivered upon settlement.

To avoid negative accounting treatment, the Company and/or its Subsidiaries may withhold or account for Tax-Related Items by considering applicable statutory withholding amounts or other applicable withholding rates. If the obligation for Tax-Related Items is satisfied by withholding in Shares, for tax purposes, the Grantee is deemed to have been issued the full number of Shares attributable to the awarded PSUs, notwithstanding that a number of Shares are held back solely for the purpose of paying the Tax-Related Items due as a result of any aspect of the Grantee’s participation in the Plan.

The Grantee shall pay to the Company and/or its Subsidiaries any amount of Tax-Related Items that the Company and/or its Subsidiaries may be required to withhold or account for as a result of the Grantee’s participation in the Plan that are not satisfied by the means previously described. The Company may refuse to issue or deliver the Shares or the proceeds of the sale of Shares, if the Grantee fails to comply with the Grantee’s obligations in connection with the Tax-Related Items.

By accepting this grant of PSUs, the Grantee expressly consents to the methods of withholding Tax-Related Items by the Company and/or its subsidiaries as set forth hereunder, including the withholding of Shares and the withholding from the Grantee’s wages/salary or other amounts payable to the Grantee.

Capitalized terms not otherwise defined herein shall have the meaning ascribed to them in the Agreement and the Plan.

The sole Performance Goal shall be the Company’s 2018 Company Operating Income. “2018 Company Operating Income” means the operating income from continuing operations before income taxes for the Company’s 2018 fiscal year, calculated in accordance with generally accepted accounting principles in the United States, subject to adjustment to exclude from the calculation thereof non-recurring and extraordinary charges and expenses, including non-GAAP adjustments for revenue/expenses, such as restructuring, special legal expenses, mergers and strategic initiatives, sublease reserves, asset retirement/impairments and other non-operating revenue/expenses (collectively, the “Non-Recurring Expenses”). Notwithstanding the foregoing, 2018 Company Operating Income shall exclude the impact of Nasdaq NEXT, foreign exchange, intra-year acquisitions and other Non-Recurring Expenses.

The Committee will rely on the Company’s audited financial statements and related information for purposes of determining the amount, if any, of 2018 Company Operating Income.

Each PSU shall, subject to the vesting provisions set forth in the Agreement, entitle the Grantee to 0.5 Shares for the achievement of “floor” 2018 Company Operating Income, 1.0 Share for the achievement of “target” 2018 Company Operating Income, and 1.5 Shares for the achievement of “ceiling” 2018 Company Operating Income.

$1,121.0 million	$1,188.0 to $1,198.0 million	$1,236.0 million

For 2018 Company Operating Income below the “floor” dollar level, no Shares shall be deliverable to the Grantee. For 2018 Company Operating Income between (i) the “floor” dollar

13

level and the “target” dollar range or (ii) between the “target” dollar range and the “ceiling” dollar level (as specified in the table above), the number of whole and/or partial Shares deliverable with respect to each Performance Share Unit will be adjusted proportionately based on the level of achievement.

Exhibit 10.5

NASDAQ, INC.THREE-YEAR PERFORMANCE SHARE UNIT AGREEMENT

This PERFORMANCE SHARE UNIT AGREEMENT (this “Agreement”) between Nasdaq, Inc., a Delaware corporation (the “Company”), and [EMPLOYEE NAME] (the “Grantee”) memorializes the grant by the Management Compensation Committee of the Board of Directors of the Company (the “Committee”) on [DATE] (the “Grant Date”) of performance share units (the “PSUs”) to the Grantee on the terms and conditions set out below.

RECITALS:

The Company has adopted the Nasdaq, Inc. Equity Incentive Plan (the “Plan”), which Plan is incorporated herein by reference and made a part of this Agreement. Capitalized terms not otherwise defined herein shall have the meaning ascribed to them in the Plan. The Plan in relevant part provides for the issuance of stock-based awards that are subject to the attainment of performance goals as established by the Committee.

The Committee has determined that it is in the best interests of the Company and its shareholders to grant the PSUs provided for herein to the Grantee pursuant to the Plan and under the terms set forth herein as an increased incentive for the Grantee to contribute to the Company’s future success and prosperity.

Capitalized terms not otherwise defined herein shall have the meaning ascribed to them in the Plan.

NOW, THEREFORE, in consideration of the mutual covenants hereinafter set forth, the parties hereto agree as follows:

1.Grant of Performance-Based Award. The Company hereby grants to the Grantee [TARGET NUMBER OF SHARES] PSUs, which PSUs shall entitle the Grantee to receive up to [200% OF TARGET NUMBER OF SHARES] Shares (or a lesser number of Shares, or no Shares whatsoever), subject to the terms and conditions set forth in this Agreement and the Plan. (A complete copy of the Plan, as in effect on the Grant Date, is available to the Grantee upon request.). Shares corresponding to the PSUs granted herein are in all events to be delivered to the Grantee only after the Grantee has become vested in the PSUs pursuant to Section 4, below.

2.Performance Period. For purposes of this Agreement, the term “Performance Period” shall be the period commencing on January 1, 2018 and ending on December 31, 2020.

3.Performance Goal.

(a)Subject to the following sentence, the Performance Goal is set out in Appendix A hereto, which Appendix A is incorporated by reference herein and made a part hereof. Notwithstanding the foregoing, the provisions of Section 13 or any other provision of this Agreement to the contrary, the Committee reserves the right to unilaterally change or

A-1

otherwise modify the Performance Goal in any manner whatsoever (including substituting a new Performance Goal). If the Committee exercises such discretionary authority to any extent, the Committee shall provide the Grantee with a new Appendix A in substitution for the Appendix A attached hereto, and such new Appendix A and the Performance Goal set out therein (rather than the Appendix A attached hereto and the Performance Goal set out therein) shall in all events apply for all purposes of this Agreement.

(b)Depending upon the extent, if any, to which the Performance Goal has been achieved, and subject to compliance with the requirements of Section 4, each PSU shall entitle the Grantee to receive, at such time as is determined in accordance with the provisions of Section 5, between 0 and 2.0 Shares for each PSU. The Committee shall, as soon as practicable following the last day of the Performance Period, certify (i) the extent, if any, to which, in accordance with Appendix A, the Performance Goal has been achieved with respect to the Performance Period and (ii) the number of whole and/or partial Shares, if any, which, subject to compliance with the vesting requirements of Section 4, the Grantee shall be entitled to receive with respect to each PSU (with such number of whole and/or partial Shares being hereafter referred to as the “Share Delivery Factor”). Such certification shall be final, conclusive and binding on the Grantee, and on all other persons, to the maximum extent permitted by law.

4.Vesting.

(a)The PSUs are subject to forfeiture to the Company until they become non-forfeitable in accordance with this Section 4. Except as provided in the following sentence, the risk of forfeiture will lapse on the PSUs, and such PSUs shall thereupon become vested, only if the Grantee remains employed by the Company through and on December 31, 2020 (the “Vest Date”). Notwithstanding the foregoing, if the Grantee’s employment with the Company terminates by reason of death prior to December 31, 2020, the risk of forfeiture shall lapse on all PSUs, and all unvested PSUs shall thereupon become vested on the date of death (or, if later, on the date, following the end of the Performance Period on which the Committee determines whether, and to what extent the PSUs are earned in accordance with Section 3(b) of this Agreement).

(b)Subject to any conflicting provisions in any employment agreement between the Company and the Grantee, which shall control in the event of a conflict with this Agreement, in the event that (i) the Company terminates the Grantee’s employment with the Company for any reason prior to the Vest Dateor (ii) the Grantee terminates employment with the Company for any reason (other than death) prior to such date, all unvested PSUs shall be cancelled and forfeited, effective as of the Grantee’s separation from service. Notwithstanding anything to the contrary in the Plan or this Agreement, and for purposes of clarity, any separation from service shall be effective as of the date the Grantee’s active employment ends and shall not be extended by any statutory or common law notice period.

5.Delivery of Shares.As soon as practicable following the Vest Date, and compliance with all applicable tax withholding as described in Section 11 hereof, but in no event later than two and one-half months after the end of the calendar year in which the Vest Date occurs, the Company shall instruct the registrar for the Company to make an entry on its books and records evidencing that the Shares underlying such vested PSUs have been duly issued as of that date; provided, however, that the Grantee may, in the alternative, elect in writing prior thereto to receive a stock certificate representing the full number of Shares acquired, which certificate may bear a restrictive legend prohibiting the transfer of such Shares for such period as may be prescribed by the Company. The Company shall not be liable to the Grantee for damages relating to any delays in issuing the certificates. The underlying Shares may be registered in the name of the Grantee’s legal representative or estate in the event of the death of the Grantee. In the event of the acceleration of the lapse of forfeiture restrictions upon the death of the Grantee as contemplated by Section 4(a) of this Agreement, this process shall occur as soon as possible following such vesting date, but in no event later than two and one-half months after the end of the calendar year in which such vesting date occurs. Notwithstanding anything in the Agreement, the Company may make delivery of Shares in settlement of PSUs by either (A) delivering certificates representing such Shares to the Grantee, registered in the name of the Grantee, or (B) by depositing such Shares into a stock brokerage account maintained for the Grantee.

6.Electronic Delivery. The Company may, in its sole discretion, decide to deliver any documents related to the PSUs or future Awards granted under the Plan by electronic means or request the Grantee’s consent to participate in the Plan by electronic means. By accepting this Award, the Grantee hereby consents and agrees to receive such documents by electronic delivery and agrees to participate in the Plan through an on-line or electronic system established and maintained by the Company or another third party designated by the Company.

7.Transferability.

(a)Except as provided below, or except to the minimal extent required by law, the PSUs are nontransferable and may not be assigned, alienated, pledged, attached, sold or otherwise transferred or encumbered by the Grantee, except by will or the laws of descent and distribution, and upon any such transfer, by will or the laws of descent and distribution (or upon such transfer required by law), the transferee shall hold such PSUs subject to all the terms and conditions that were applicable to the Grantee immediately prior to such transfer. Notwithstanding the foregoing, the Grantee may transfer any vested PSUs to members of his immediate family (defined as his spouse, children or grandchildren) or to one or more trusts for the exclusive benefit of such immediate family members or partnerships in which such immediate family members are the only partners if the transfer is approved by the Committee and the Grantee does not receive any consideration for the transfer. Any such transferred portion of the PSUs shall continue to be subject to the same terms and conditions that were applicable to such portion of the PSUs immediately prior to transfer (except that such transferred PSUs shall not be further transferable by the transferee). No transfer of a portion of the PSUs shall be effective to bind the Company unless the Company shall have been furnished with written notice

3

thereof and a copy of such evidence as the Committee may deem necessary to establish the validity of the transfer and the acceptance by the transferee of the terms and conditions hereof.

(b)Upon any transfer by will or the laws of descent and distribution (or upon any such transfer required by law), such transferee shall take the PSUs and the Shares delivered in connection therewith (the “Transferee Shares”) subject to all the terms and conditions that were (or would have been) applicable to the PSUs and the Transferee Shares immediately prior to such transfer.

(c)Following settlement and issuance of Shares, in the event the Company permits Grantee to arrange for sale of Shares through a broker or another designated agent of the Company, Grantee acknowledges and agrees that the Company may block any such sale and/or cancel any order to sell placed by the Grantee, in each case if the Grantee is not then permitted under the Company’s insider trading policy to engage in transactions with respect to securities of the Company. If the Committee determines that the ability of the Grantee to sell or transfer shares of Common Stock is restricted, then the Company may notify the Grantee in accordance with Section 12 of this Agreement. The Grantee may only sell such Shares in compliance with such notification from the Company.

8.Rights of Grantee. Prior to the delivery, if any, of Shares to the Grantee pursuant to the provisions of Section 5, the Grantee shall not have any rights of a shareholder of the Company, including, but not limited to, the right to receive dividend payments, on account of the PSUs.

9.Unfunded Nature of PSUs. The Company will not segregate any funds representing the potential liability arising under this Agreement. The Grantee’s rights in respect of this Agreement are those of an unsecured general creditor of the Company. The liability for any payment under this Agreement will be a liability of the Company and not a liability of any of its officers, directors or Affiliates.

10.Securities Laws. The Company may condition delivery of Shares for any vested PSUs upon the prior receipt from the Grantee of any undertakings which it may determine are required to assure that the Shares are being issued in compliance with federal and state securities laws.

11.Withholding. Regardless of any action the Company, any of its Subsidiaries and/or the Grantee's employer takes with respect to any or all income tax, social insurance, payroll tax, payment on account or other tax-related items related to the Grantee’s participation in the Plan and legally applicable to the Grantee (“Tax-Related Items”), the Grantee acknowledges that the ultimate liability for all Tax-Related Items is and remains the Grantee’s responsibility and may exceed the amount actually withheld by the Company or any of its affiliates. The Grantee further acknowledges that the Company and/or its Subsidiaries (i) make no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of the PSUs, including, but not limited to, the grant, vesting or settlement of the PSUs, the issuance of Shares or cash upon settlement of the PSUs, the subsequent sale of Shares acquired pursuant to such delivery and the receipt of any dividends

and/or dividend equivalents; and (ii) do not commit to and are under no obligation to structure the terms of any award to reduce or eliminate the Grantee’s liability for Tax-Related Items or achieve any particular tax result. Further, if the Grantee becomes subject to tax in more than one jurisdiction between the Grant Date and the date of any relevant taxable event, the Grantee acknowledges that the Company and/or its Subsidiaries may be required to withhold or account for Tax-Related Items in more than one jurisdiction.

Prior to any relevant taxable or tax withholding event, as applicable, the Grantee will pay or make adequate arrangements satisfactory to the Company and/or its Subsidiaries to satisfy all Tax-Related Items. In this regard, the Grantee authorizes the Company and/or its Subsidiaries, or their respective agents, at their discretion, to satisfy the obligations with regard to all Tax-Related Items by one or a combination of the following:

(a) withholding from the Grantee’s wages or other cash compensation paid to the Grantee by the Company and/or its Subsidiaries; or

(b) withholding from proceeds of the Shares acquired following settlement either through a voluntary sale or through a mandatory sale arranged by the Company (on the Grantee’s behalf pursuant to this authorization); or

(c) withholding in Shares to be delivered upon settlement.

To avoid negative accounting treatment, the Company and/or its Subsidiaries may withhold or account for Tax-Related Items by considering applicable statutory withholding amounts or other applicable withholding rates. If the obligation for Tax-Related Items is satisfied by withholding in Shares, for tax purposes, the Grantee is deemed to have been issued the full number of Shares attributable to the awarded PSUs, notwithstanding that a number of Shares are held back solely for the purpose of paying the Tax-Related Items due as a result of any aspect of the Grantee’s participation in the Plan.

The Grantee shall pay to the Company and/or its Subsidiaries any amount of Tax-Related Items that the Company and/or its Subsidiaries may be required to withhold or account for as a result of the Grantee’s participation in the Plan that are not satisfied by the means previously described. The Company may refuse to issue or deliver the Shares or the proceeds of the sale of Shares, if the Grantee fails to comply with the Grantee’s obligations in connection with the Tax-Related Items.

By accepting this grant of PSUs, the Grantee expressly consents to the methods of withholding Tax-Related Items by the Company and/or its subsidiaries as set forth hereunder, including the withholding of Shares and the withholding from the Grantee’s wages/salary or other amounts payable to the Grantee. All other Tax-Related Items related to the PSUs and any Shares delivered in satisfaction thereof are the Grantee’s sole responsibility.

12.Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of Delaware, without giving effect to any principle of law that could result in the application of the law of any other jurisdiction.

Any such amendments shall be made in a manner that preserves to the maximum extent possible the intended benefits to Grantee. This paragraph does not create an obligation on the part of Company to modify this Agreement and does not guarantee that the amounts or benefits owed under the Agreement will not be subject to interest and penalties under Code Section 409A.

16.Imposition of Other Requirements. The Company reserves the right to impose other requirements on the Grantee’s participation in the Plan, on the PSUs and on any Shares acquired under the Plan, to the extent the Company determines it is necessary or advisable in order to comply with local law or facilitate the administration of the Plan, and to require the Grantee to sign any additional agreements or undertakings that may be necessary to accomplish the foregoing. The Grantee agrees, upon demand of the Company or the Committee, to do all acts and execute, deliver and perform all additional documents, instruments and agreements which may be reasonably required by the Company or the Committee, as the case may be, to implement the provisions and purposes of the Plan and this Agreement.

17.No Right to Continued Employment. This Agreement shall not confer on the Grantee any right to be retained, in any position, as an employee, consultant or director of the Company.

The grant of the Award represented by this Agreement is exceptional, voluntary and occasional and does not create any contractual or other right to receive an award or benefit in lieu of an award in the future, even if awards have been granted repeatedly in the past. Future Awards, if any, will be at the sole discretion of the Company, including, but not limited to, the form and timing of an Award, the number of Shares subject to the Award, and the vesting provisions. Any amendment, modification or termination of the Plan shall not constitute a change or impairment of the terms and conditions of the Grantee’s employment with the Company.

22.Termination Indemnities. The Grantee’s Award and the Shares subject to the Award, and the income and value of the same, are extraordinary items of compensation outside the scope of the Grantee’s employment or services contract, if any. As such, the PSUs are not part of normal or expected compensation for purposes of calculating any severance, resignation, termination, redundancy, dismissal, end of service payments, bonuses, long-service awards, pension, or retirement benefits or welfare benefits or similar payments.

23.English Language. The Grantee acknowledges and agrees that it is the Grantee’s express intent that the Plan, this Agreement, any addendum and all other documents, notices and legal proceedings entered into, given or instituted pursuant to the Award, be drawn up in English.

(ii) all decisions with respect to future Awards or other grants, if any, will be at the sole discretion of the Company;

The collection, processing and transfer of the Grantee’s personal data are necessary for the Company’s administration of the Plan and the Grantee’s participation in the Plan. The Grantee’s denial and/or objection to the collection, processing and transfer of personal data may affect the Grantee’s participation in the Plan.

8

The Data may be provided by the Grantee or collected, where lawful, from third parties, and the Company will process the Data for the exclusive purpose of implementing, administering and managing the Grantee’s participation in the Plan. The Data processing will take place through electronic and non-electronic means according to logics and procedures strictly correlated to the purposes for which Data are collected and with confidentiality and security provisions as set forth by applicable laws and regulations in the Grantee’s country of residence. Data processing operations will be performed minimizing the use of personal and identification data when such operations are unnecessary for the processing purposes sought. Data will be accessible within the Company’s organization only by those persons requiring access for purposes of the implementation, administration and operation of the Plan and for the Grantee’s participation in the Plan.

The Company and the Grantee’s employer will transfer Data amongst themselves as necessary for the purpose of implementation, administration and management of the Grantee’s participation in the Plan, and the Company and the Grantee’s employer may each further transfer Data to any third parties assisting the Company in the implementation, administration and management of the Plan.

The Grantee may, at any time, exercise his or her rights provided under applicable personal data protection laws, which may include the right to (a) obtain confirmation as to the existence of the Data, (b) verify the content, origin and accuracy of the Data, (c) request the integration, update, amendment, deletion, or blockage (for breach of applicable laws) of the Data, and (d) to oppose, for legal reasons, the collection, processing or transfer of the Data which is not necessary or required for the implementation, administration and/or operation of the Plan and the Grantee’s participation in the Plan. The Grantee may seek to exercise these rights by contacting the Grantee’s local human resources manager.

Finally, upon request of the Company or the Grantee’s employer, the Grantee agrees to provide an executed data privacy consent form (or any other agreements or consents that may be required

9

by the Company and/or the Grantee’s employer) that the Company and/or the Grantee’s employer may deem necessary to obtain from the Grantee for the purpose of administering the Grantee’s participation in the Plan in compliance with the data privacy laws in the Grantee’s country, either now or in the future. The Grantee understands and agrees that the Grantee will not be able to participate in the Plan if the Grantee fails to provide any such consent or agreement requested by the Company and/or the Grantee’s employer.

26.Private Placement. The grant of the PSUs is not intended to be a public offering of securities in the Grantee’s country of residence (and country of employment, if different). The Company has not submitted any registration statement, prospectus or other filings with the local securities authorities (unless otherwise required under local law), and the grant of the PSUs is not subject to the supervision of the local securities authorities.

27.Addendum to Agreement. Notwithstanding any provisions of this Agreement to the contrary, the Award shall be subject to any special terms and conditions for the Grantee’s country of residence (and country of employment, if different), as are set forth in the applicable addendum (the “Addendum”) as attached to the Agreement. Further, if the Grantee transfers residence and/or employment to another country reflected in an Addendum to the Agreement, the special terms and conditions for such country will apply to the Grantee to the extent the Company determines, in its sole discretion, that the application of such terms is necessary or advisable in order to comply with local laws, rules and regulations or to facilitate operation and administration of the Plan. Any applicable Addendum shall constitute part of this Agreement.

28.No Advice Regarding Grant. The Company is not providing any tax, legal or financial advice, nor is the Company making any recommendations regarding the Grantee's participation in the Plan, or his acquisition or sale of the underlying Shares.

30.Execution. This Agreement may be executed, including execution by facsimile signature, in one or more counterparts, each of which will be deemed an original, and all of which together shall be deemed to be one and the same instrument.

31.Insider Trading / Market Abuse Laws. The Grantee acknowledges that, depending on the Grantee’s or the Grantee’s broker’s country of residence or where the Shares are listed, the Grantee may be subject to insider trading and/or market abuse laws, which may affect the Grantee’s ability to accept, acquire, sell or otherwise dispose of Shares, rights to shares (e.g., PSUs) or rights linked to the value of shares (e.g., phantom awards, futures) during such times as the Grantee is considered to have “inside information” regarding the Company as defined by the laws or regulations in the Grantee’s country. Local insider trading laws and regulations may prohibit the cancellation or amendment or amendment of orders the Grantee

10

placed before the Grantee possessed inside information.

Appendix A

Performance Goals for PSU Grant

2018-2020 Performance Period

This Appendix A to the Agreement sets forth the Performance Goals to be achieved and, depending upon the extent (if any) to which the Performance Goals are achieved, the number of whole and/or partial Shares, if any, which the Grantee shall have the right to receive with respect to each PSU. Capitalized terms not otherwise defined herein shall have the meaning ascribed to them in the Agreement and the Plan.

Certain Definitions

“Closing Price” means the 30-day calendar average closing price of a share of a company’s stock ending on the last trading day of the Performance Period.

“Opening Price” means the 30-day calendar average closing price of a share of a company’s stock ending on the trading day preceding the first day of the Performance Period. The Opening Price shall be adjusted for stock splits and reverse stock splits that occur during the Performance Period.

“Payout Governor” means that regardless of percentile ranking for either Performance Goal, if the Company’s TSR is negative, the Grantee shall be entitled to receive no more than 100% of the PSUs.

“Peer Group” means a group of peer companies consisting of the following global exchanges: ASX Ltd, BM&F Bovespa, Bolsa Mexicana de Valores, Bolsas Y Mercados Espanoles, CBOE Holdings Inc, CME Group Inc, Deutsche Boerse AG, Euronext, Hong Kong Exchange, Intercontinental Exchange, Japan Exchange, London Stock Exchange Group plc, NEX Group plc, Singapore Exchange and TMX Group Inc.

“Price Cap” means that regardless of the actual stock price growth over the Performance Period, the final stock price will be limited to 250% of the grant date price for purposes of calculating the final award of PSUs to the Grantee.

“S&P 500” means the companies constituting the Standard & Poor’s 500 Index as of the beginning of the Performance Period. Any component company of the Standard & Poor’s 500 Index that is acquired, taken private, delisted, liquidated or no longer publicly traded due to filing for bankruptcy protection at any time during the Performance Period will be eliminated from the S&P 500 for the entire Performance Period. There will be no adjustments to the S&P 500 to account for any other changes to the Standard & Poor’s 500 Index during the Performance Period.

13

“TSR” means the total shareholder return during the Performance Period, which will be calculated as the (i) Closing Price minus Opening Price plus cumulative dividends, divided by (ii) Opening Price. No adjustments to TSR shall be made for stock issuances or stock buybacks during the Performance Period. Each company’s TSR shall be calculated in the local currency to eliminate foreign exchange fluctuations.

Goal 1: TSR Performance Relative to the S&P 500

The Performance Goal for 50% of the PSUs shall be the Company’s three-year TSR percentile rank versus the S&P 500.

For this portion of the award, each PSU shall, subject to the vesting provisions set forth in the Agreement and the Payout Governor, entitle the Grantee to receive Shares based on the levels of achievement in the following table.

Table 1: Levels of Achievement

Percentile Rank of the Company’s Three-Year TSR Versus the S&P 500	Resulting Shares Earned (% of Half of Target)
≥85th Percentile	200%
67.5th Percentile	150%
50th Percentile	100%
25th Percentile	50%
15th Percentile	30%
0 Percentile	0%

For levels of achievement between points, the resulting Shares earned will be calculated based on straight-line interpolation.

The resulting shares earned will be subject to the 250% Price Cap. If the Nasdaq stock price grows greater than 250% over the Performance Period, the resulting number of shares will be fewer than 200% of target shares. For example: (formulaic resulting shares earned X 250% Price Cap) / (stock price at time of delivery of shares) = resulting actual shares earned.

Goal 2: TSR Performance Relative to a Peer Group

The Performance Goal for 50% of the PSUs shall be the Company’s three-year TSR percentile rank versus the Peer Group. For this portion of the award, each PSU shall, subject to the vesting provisions set forth in the Agreement and the Payout Governor, entitle the Grantee to receive Shares based on the levels of achievement in the following table.

14

Table 2: Levels of Achievement

Percentile Rank of the Company’s Three-Year TSR Versus the Peer Group	Resulting Shares Earned (% of Half of Target)
≥85th Percentile	200%
67.5th Percentile	150%
50th Percentile	100%
25th Percentile	50%
15th Percentile	30%
0 Percentile	0%

For levels of achievement between points, the resulting Shares earned will be calculated based on straight-line interpolation.

The resulting shares earned will be subject to the 250% Price Cap. If the Nasdaq stock price grows greater than 250% over the Performance Period, the resulting number of shares will be fewer than 200% of target shares. For example: (formulaic resulting shares earned X 250% Price Cap) / (stock price at time of delivery of shares) = resulting actual shares earned.

Other Terms and Conditions

To the extent consistent with the Code and the Plan, the Committee reserves the right to modify any calculation described in this Appendix A to adjust for unanticipated circumstances or situations, as it deems necessary. All actions taken by the Committee pursuant to this Appendix A shall be final, conclusive and binding upon the Grantee, and all other persons, to the maximum extent permitted by law.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Organization and Nature of Operations

Organization and Nature of Operations

Nasdaq, Inc. is a leading provider of trading, clearing, marketplace technology, regulatory, securities listing, information and public and private company services. Our global offerings are diverse and include trading and clearing across multiple asset classes, trade management services, market data products, financial indexes, capital formation solutions, corporate solutions, and market technology products and services. Our technology powers markets across the globe, supporting equity derivative trading, clearing and settlement, cash equity trading, fixed income trading, trading surveillance and many other functions.

We manage, operate and provide our products and services in four business segments: Market Services, Corporate Services, Information Services and Market Technology.

Market Services

Our Market Services segment includes our Equity Derivative Trading and Clearing, Cash Equity Trading, FICC and Trade Management Services businesses. We operate multiple exchanges and other marketplace facilities across several asset classes, including derivatives, commodities, cash equity, debt, structured products and ETPs. In addition, in some countries where we operate exchanges, we also provide broker services, clearing, settlement and central depository services. Our transaction-based platforms provide market participants with the ability to access, process, display and integrate orders and quotes. The platforms allow the routing and execution of buy and sell orders as well as the reporting of transactions, providing fee-based revenues.

In the U.S., we operate six electronic options exchanges and three cash equity exchanges. The Nasdaq Stock Market, the largest of our cash equities exchanges, is the largest single venue of liquidity for trading U.S.-listed cash equities. We also operate an electronic platform for trading of U.S. Treasuries and NFX, a U.S. based designated contract market which lists cash-settled energy derivatives based on key energy benchmarks including oil, natural gas and U.S. power. In addition, we also operate a Canadian exchange for the trading of Canadian-listed securities.

In Europe, we operate exchanges in Stockholm (Sweden), Copenhagen (Denmark), Helsinki (Finland), and Reykjavik (Iceland), as well as the clearing operations of Nasdaq Clearing, as Nasdaq Nordic. We also operate exchanges in Tallinn (Estonia), Riga (Latvia) and Vilnius (Lithuania) as Nasdaq Baltic. Collectively, Nasdaq Nordic and Nasdaq Baltic offer trading in cash equities, depository receipts, warrants, convertibles, rights, fund units and ETFs, as well as trading and clearing of derivatives and clearing of resale and repurchase agreements.

Nasdaq Commodities is the brand name for Nasdaq’s worldwide suite of commodity-related products and services. Nasdaq Commodities’ offerings include oil, power, natural gas and carbon emission markets, tanker and dry cargo freight, seafood derivatives, iron ore, electricity certificates and clearing services. These products are listed on two of Nasdaq’s derivatives exchanges, Nasdaq Oslo ASA and NFX.

Through our Trade Management Services business, we provide market participants with a wide variety of alternatives for connecting to and accessing our markets via a number of different protocols used for quoting, order entry, trade reporting, DROP functionality and connectivity to various data feeds. We also provide data center services, including co-location to market participants, whereby firms may lease cabinet space and power to house their own equipment and servers within our data centers. Our broker services operations offer technology and customized securities administration solutions to financial participants in the Nordic market.

Corporate Services

Our Corporate Services segment includes our Corporate Solutions and Listing Services businesses.

Our Corporate Solutions business serves corporate clients, including companies listed on our exchanges and private companies. We help organizations manage the two-way flow of information with their key constituents, including their board members and investors, and with clients and the public through our suite of advanced technology, analytics, and consultative services. In April 2018, we sold our Public Relations Solutions and Digital Media Services businesses. See “2018 Divestiture,” of Note 4, “Divestiture and Acquisitions,” for further discussion. As of June 30, 2018, our Corporate Solutions business includes our investor relations, board & leadership, and governance, risk and compliance products and services.

For segment reporting purposes, we have included in corporate items the revenues and expenses of the Public Relations Solutions and Digital Media Services businesses, which were part of the Corporate Solutions business, within our Corporate Services segment, prior to the date of sale. See Note 18, “Business Segments,” for further discussion.

We have realigned our businesses to better serve the needs of our corporate clients. As a result, beginning in the second quarter of 2018, our BWise corporate enterprise risk management solutions are now offered as part of governance, risk and compliance products and services within our Corporate Solutions business. BWise was previously part of our Market Technology segment.

Our Listing Services business includes our U.S. and European Listing Services businesses. We operate a variety of listing platforms around the world to provide multiple global capital raising solutions for private and public companies. Our main listing markets are The Nasdaq Stock Market and the Nasdaq Nordic and Nasdaq Baltic exchanges. Through Nasdaq First North, our Nordic and Baltic operations also offer alternative marketplaces for smaller companies and growth companies. Our Listing Services business also includes NPM, which provides liquidity solutions for private companies.

As of June 30, 2018, there were 3,004 total listings on The Nasdaq Stock Market, including 380 ETPs. The combined market capitalization was approximately $12.5 trillion. In Europe, the Nasdaq Nordic and Nasdaq Baltic exchanges, together with Nasdaq First North, were home to 1,008 listed companies with a combined market capitalization of approximately $1.5 trillion.

Information Services

Beginning in the second quarter of 2018, our Information Services segment was recategorized into the following businesses:

• Market Data;

• Index; and

• Investment Data & Analytics.

Prior to the second quarter, our Information Services segment was comprised of our Data Products and our Index Licensing and Services businesses.

Our Market Data business sells and distributes historical and real-time quote and trade information to the sell-side, the buy-side, retail online brokers, proprietary trading shops, other venues, internet portals and data distributors. Our market data products enhance transparency of market activity within our exchanges and provide critical information to professional and non-professional investors globally.

Our Index business develops and licenses Nasdaq-branded indexes, associated derivatives, and financial products and also provides custom calculation services for third-party clients. As of June 30, 2018, we had 347 ETPs licensed to Nasdaq’s indexes which had $187 billion in assets under management.

Our Investment Data & Analytics business is a leading content and analytics cloud-based solutions provider used by asset managers, investment consultants and asset owners to help facilitate better investment decisions.

Market Technology

Our Market Technology segment is a leading global technology solutions provider and partner to exchanges, clearing organizations, central securities depositories, regulators, banks, brokers and corporate businesses. Our Market Technology business is the sales channel for our complete global offering to other marketplaces.

Market Technology provides technology solutions for trading, clearing, settlement, surveillance and information dissemination to markets with wide-ranging requirements, from the leading markets in the U.S., Europe and Asia to emerging markets in the Middle East, Latin America, and Africa. Our marketplace solutions can handle a wide array of assets, including cash equities, equity derivatives, currencies, various interest-bearing securities, commodities and energy products, and are currently powering more than 100 marketplaces in 50 countries. Market Technology also provides market surveillance services to broker-dealer firms worldwide, as well as risk management solutions.

As discussed above under “Corporate Services,” as of the second quarter of 2018, our BWise business which was previously part of our Market Technology segment is now offered as part of our Corporate Solutions business.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation and Principles of Consolidation

Basis of Presentation and Principles of Consolidation

The condensed consolidated financial statements are prepared in accordance with U.S. GAAP and include the accounts of Nasdaq, its wholly-owned subsidiaries and other entities in which Nasdaq has a controlling financial interest. When we do not have a controlling interest in an entity but exercise significant influence over the entity’s operating and financial policies, such investment is accounted for under the equity method of accounting. We recognize our share of earnings or losses of an equity method investee based on our ownership percentage. See “Equity Method Investments,” of Note 7, “Investments,” for further discussion of our equity method investments.

The accompanying condensed consolidated financial statements reflect all adjustments which are, in the opinion of management, necessary for a fair statement of the results for the interim periods presented. These adjustments are of a normal recurring nature. All significant intercompany accounts and transactions have been eliminated in consolidation.

As permitted under U.S. GAAP, certain footnotes or other financial information can be condensed or omitted in the interim condensed consolidated financial statements. The information included in this Quarterly Report on Form 10-Q should be read in conjunction with the consolidated financial statements and accompanying notes included in Nasdaq’s Annual Report on Form 10-K for the fiscal year ended December 31, 2017.

Certain prior year amounts have been reclassified to conform to the current year presentation primarily due to the adoption of ASU 2014-09, “Revenue from Contracts with Customers (Topic 606),” on January 1, 2018. See Note 3, “Significant Accounting Policies Update,” for further discussion.

The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts and the disclosure of contingent amounts in the condensed consolidated financial statements and accompanying notes. Actual results could differ from those estimates.

Subsequent Events

We have evaluated subsequent events through the issuance date of this Quarterly Report on Form 10-Q.

Recent Accounting Pronouncements

Accounting Standard	Description	Effective Date	Effect on the Financial Statements or Other Significant Matters
Income Statement - Reporting Comprehensive Income In February 2018, the FASB issued ASU 2018-02, “Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (Topic 220).”	This ASU provides an election to reclassify tax effects that are stranded in accumulated other comprehensive income as a result of tax reform to retained earnings. An election is also available to reclassify other stranded tax effects that relate to the Tax Cuts and Jobs Act but do not directly relate to the change in the federal rate. Tax effects that are stranded in accumulated other comprehensive income for other reasons (e.g., prior changes in tax law, a change in valuation allowance) may not be reclassified. Previously, the effects of changes in tax rates and laws on deferred tax balances were required to be recorded as a component of tax expense related to continuing operations for the period in which the law was enacted, even if the assets and liabilities related to items of accumulated other comprehensive income. In other words, backward tracing of the income tax effects of items originally recognized through accumulated other comprehensive income was prohibited.	January 1, 2019, with early adoption permitted. We early adopted this standard on January 1, 2018.	As a result of the adoption of this standard, in the first quarter of 2018, we recorded a reclassification of $142 million for stranded tax effects related to the Tax Cuts and Jobs Act from accumulated other comprehensive loss to retained earnings within stockholders’ equity in the Condensed Consolidated Balance Sheets. See Note 17, “Income Taxes,” for further discussion.
Goodwill In January 2017, the FASB issued ASU 2017-04, “Simplifying the Test for Goodwill Impairment.”	This ASU simplifies how an entity is required to test goodwill for impairment and removes the second step of the goodwill impairment test, which required a hypothetical purchase price allocation if the fair value of a reporting unit is less than its carrying amount. Goodwill impairment will now be measured using the difference between the carrying amount and the fair value of the reporting unit and the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. The amendments in this ASU should be applied on a prospective basis.	January 1, 2020, with early adoption permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017.	We do not anticipate a material impact on our consolidated financial statements at the time of adoption of this new standard as the carrying amounts of our reporting units have been less than their corresponding fair values in recent years. Therefore, the second step of the goodwill impairment test was not required. However, changes in future projections, market conditions and other factors may cause a change in the excess of fair value of our reporting units over their corresponding carrying amounts. We do not anticipate early adoption of this standard.
Financial Instruments - Credit Losses In June 2016, the FASB issued ASU 2016-13, “Measurement of Credit Losses on Financial Instruments.”	This ASU changes the impairment model for certain financial instruments. The new model is a forward looking expected loss model and will apply to financial assets subject to credit losses and measured at amortized cost and certain off-balance sheet credit exposures. This includes loans, held-to-maturity debt securities, loan commitments, financial guarantees and net investments in leases, as well as trade receivables. For available-for-sale debt securities with unrealized losses, credit losses will be measured in a manner similar to today, except that the losses will be recognized as allowances rather than reductions in the amortized cost of the securities.	January 1, 2020, with early adoption permitted as of January 1, 2019.	We are currently assessing the impact that this standard will have on our consolidated financial statements. We do not anticipate early adoption of this standard.

Accounting Standard	Description	Effective Date	Effect on the Financial Statements or Other Significant Matters
Leases In February 2016, the FASB issued ASU 2016-02, “Leases.”	Under this ASU, at the commencement date, lessees will be required to recognize a lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis; and a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. This guidance is not applicable for leases with a term of 12 months or less. Recognition, measurement and presentation of expenses will depend on classification as a finance or operating lease. The guidance also requires certain quantitative and qualitative disclosures about leasing arrangements. Lessor accounting is largely unchanged. In transition, lessees and lessors are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach.	January 1, 2019, with early adoption permitted.	See discussion below.

Leases

When adopted, ASU 2016-02 will result in an increase in the assets and liabilities reflected on our consolidated balance sheets. In addition, we will be required to disclose key information about our leases. We are in the process of determining the scope of arrangements that will be subject to this standard, as well as assessing the impact to our business processes, systems and internal controls to support adoption of this new standard. Nasdaq’s current operating lease portfolio is primarily comprised of real estate and data center leases.

We plan to adopt this new standard on January 1, 2019. The guidance is to be applied using a modified retrospective transaction approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. However, in March 2018, the FASB approved an optional transition alternative, which allows for application of the guidance at the effective date, without adjusting the comparative periods presented.

While we continue to assess the effect of adoption of this new standard and the available practical expedients, we expect that most of our operating lease commitments will be subject to the new guidance and will be recognized as right-of-use assets and lease liabilities upon adoption in our consolidated balance sheets. We do not expect the adoption of this new standard to have a material impact on our consolidated statements of income and it will not impact our cash flows.

Significant Accounting Policies Update

Accounting Policies [Abstract]

Significant Accounting Policies Update

Significant Accounting Policies Update

Our significant accounting policies are detailed in Note 2, “Summary of Significant Accounting Policies,” in our Annual Report on Form 10-K for the year ended December 31, 2017 that was filed with the SEC on February 28, 2018. Significant changes to our accounting policies as a result of adopting Topic 606 and ASU 2016-01, “Recognition and Measurement of Financial Assets and Financial Liabilities,” or ASU 2016-01, are discussed below.

Revenue From Contracts With Customers

On January 1, 2018, we adopted Topic 606 using the full retrospective method. The adoption of Topic 606 impacted the revenue and expense recognition for our Market Technology business and revenue recognition for our Listing Services business. However, the adoption of Topic 606 did not have a material impact on our consolidated financial statements at the time of adoption or in any prior reporting periods. There was no impact to revenue and expense recognition for our other businesses. Additional disclosures required by Topic 606 are provided below.

Contract Balances

Substantially all of our revenues are considered to be revenues from contracts with customers. The related accounts receivable balances are recorded in our Condensed Consolidated Balance Sheets as receivables which is net of allowance for doubtful accounts of $13 million as of June 30, 2018 and $9 million as of December 31, 2017. The changes in the balance between periods were immaterial. We do not have obligations for warranties, returns or refunds to customers.

For the majority of our contracts with customers, except for our market technology and listings services contracts, our performance obligations are short-term in nature and there is no significant variable consideration.

We do not have significant revenues recognized from performance obligations that were satisfied in prior periods. We have elected not to provide disclosures about transaction price allocated to unsatisfied performance obligations if contract durations are less than one year. For contract durations that are one-year or greater, we do not have a material portion of transaction price allocated to unsatisfied performance obligations that are not included in deferred revenue other than for our market technology contracts which are discussed below under “Market Technology.” Deferred revenue primarily represents our contract liabilities related to our fees for annual and initial listings, market technology, corporate solutions and information services contracts. Deferred revenue is the only significant contract asset or liability impacted by our adoption of Topic 606. See Note 8, “Deferred Revenue,” for our discussion on deferred revenue balances, activity, and expected timing of recognition. See “Revenue Recognition” below for further descriptions of our revenue contracts.

Sales commissions earned by our sales force are considered incremental and recoverable costs of obtaining a contract with a customer. These costs are deferred and amortized on a straight-line basis over the period of benefit that we have determined to be the contract term or estimated service periods. Sales commissions for renewal contracts are deferred and amortized on a straight-line basis over the related contractual renewal period. Amortization expense is included in compensation and benefits expense in the Condensed Consolidated Statements of Income. The balance of deferred costs and related amortization expense are not material to our consolidated financial statements. We elected the practical expedient of recognizing sales commissions as an expense when incurred if contract durations are one year or less. We also have elected the practical expedient of excluding sales taxes from transaction prices.

Certain judgments and estimates were used in the identification and timing of satisfaction of performance obligations and the related allocation of transaction price and are discussed below. We believe that these represent a faithful depiction of the transfer of services to our customers.

Revenue Recognition

Our primary revenue contract classifications are described below. Though we discuss additional revenue details in our “Management's Discussion and Analysis of Financial Condition and Results of Operations,” the categories below best represent those that depict similar economic characteristics of the nature, amount, timing and uncertainty of our revenues and cash flows.

Market Services

Transaction-Based Trading and Clearing

Transaction-based trading and clearing includes equity derivative trading and clearing revenues, cash equity trading revenues and FICC revenues. Nasdaq charges transaction fees for trades executed on our exchanges, as well as on orders that are routed to and executed on other market venues. Nasdaq charges clearing fees for contracts cleared with Nasdaq Clearing.

In the U.S., transaction fees are based on trading volumes for trades executed on our U.S. exchanges and in Europe, transaction fees are based on the volume and value of traded and cleared contracts. In Canada, transaction fees are based on trading volumes for trades executed on our Canadian exchange.

Nasdaq satisfies its performance obligation for trading services upon the execution of a customer trade and clearing services when a contract is cleared, as trading and clearing transactions are substantially complete when they are executed and we have no further obligation to the customer at that time. Transaction-based trading and clearing fees can be variable and are based on trade volume tiered discounts. Transaction revenues, as well as any tiered volume discounts, are calculated and billed monthly in accordance with our published fee schedules. In the U.S., we also pay liquidity payments to customers based on our published fee schedules. We use these payments to improve the liquidity on our markets and therefore recognize those payments as a cost of revenue.

The majority of our FICC trading and clearing customers are charged transaction fees, as discussed above, which are based on the volume and value of traded and cleared contracts. We also enter into annual fixed contracts with customers trading U.S. Treasury securities. The customers are charged an annual fixed fee which is billed per the agreement, on a monthly or quarterly basis. Revenues earned on fixed contracts are recognized over time on a ratable basis over the contract period beginning on the date that our service is made available to the customer since the customer receives and consumes the benefit as Nasdaq provides the service.

For U.S. equity derivative trading, we credit a portion of the per share execution charge to the market participant that provides the liquidity. For U.S. cash equity trading, for Nasdaq and Nasdaq PSX, we credit a portion of the per share execution charge to the market participant that provides the liquidity and for Nasdaq BX, we credit a portion of the per share execution charge to the market participant that takes the liquidity. We record these credits as transaction rebates that are included in transaction-based expense in the Condensed Consolidated Statements of Income. These transaction rebates are paid on a monthly basis and the amounts due are included in accounts payable and accrued expenses in the Condensed Consolidated Balance Sheets.

In the U.S., we pay Section 31 fees to the SEC for supervision and regulation of securities markets. We pass these costs along to our customers through our equity derivative trading and clearing fees and our cash equity trading fees. We collect the fees as a pass-through charge from organizations executing eligible trades on our options exchanges and our cash equity platforms and we recognize these amounts in transaction-based expenses when incurred. Section 31 fees received are included in cash and cash equivalents in the Condensed Consolidated Balance Sheets at the time of receipt and, as required by law, the amount due to the SEC is remitted semiannually and recorded as Section 31fees payable to the SEC in the Condensed Consolidated Balance Sheets until paid. Since the amount recorded as revenues is equal to the amount recorded as transaction-based expenses, there is no impact on our revenues less transaction-based expenses. As we hold the cash received until payment to the SEC, we earn interest income on the related cash balances.

Under our Limitation of Liability Rule and procedures, we may, subject to certain caps, provide compensation for losses directly resulting from the systems’ actual failure to correctly process an order, quote, message or other data into our platform. We do not record a liability for any potential claims that may be submitted under the Limitation of Liability Rule unless they meet the provisions required in accordance with U.S. GAAP. As such, losses arising as a result of the rule are accrued and charged to expense only if the loss is probable and estimable.

Trade Management Services

We provide market participants with a wide variety of alternatives for connecting to and accessing our markets for a fee. We also offer market participants co-location services, whereby firms may lease cabinet space and power to house their own equipment and servers within our data centers. These participants are charged monthly fees for cabinet space, connectivity and support in accordance with our published fee schedules and recognized on a monthly basis when the performance obligation is met. We also earn revenues from annual and monthly exchange membership and registration fees. Revenues for providing access to our markets, co-location services and monthly exchange membership and registration fees are recognized on a monthly basis as the service is provided. Revenues from annual fees for exchange membership and registration fees are recognized ratably over the following 12-month period since the customer receives and consumes the benefit as Nasdaq provides the service. We also offer broker services to financial participants in the Nordic market primarily providing flexible back-office systems, which allow customers to entirely or partly outsource their company’s back-office functions. Revenues from broker services are based on a fixed basic fee for administration or licensing, maintenance and operations, and an incremental fee depending on the number of transactions completed. Broker services revenues are generally billed and recognized monthly.

Corporate Solutions

As of June 30, 2018, corporate solutions revenues primarily include subscription and transaction-based income from our investor relations, board & leadership, and governance, risk and compliance products and services. In April 2018, we completed the sale of our Public Relations Solutions and Digital Media Services businesses. See “2018 Divestiture,” of Note 4, “Divestiture and Acquisitions,” for further discussion. Subscription-based revenues earned are recognized over time on a ratable basis over the contract period beginning on the date that our service is made available to the customer since the customer receives and consumes the benefit as Nasdaq provides the service. Generally, fees are billed quarterly in advance and the contract provides for automatic renewal. As part of the subscription agreements, customers can also be charged usage fees based upon actual usage of the services provided. Revenues from usage fees are recognized at a point in time upon completion of the service.

Listing Services

Listing services revenues primarily include initial listing fees and annual renewal fees. Under Topic 606, the initial listing fee is allocated to multiple performance obligations including initial and subsequent listing services and corporate solutions services (when a company qualifies to receive these services under the applicable Nasdaq rule), as well as a customer's material right to renew the option to list on our exchanges. In performing this allocation, the standalone selling price of the performance obligations is based on the initial and annual listing fees and the standalone selling price of the corporate solutions services is based on its market value. All listing fees are billed upfront and the identified performance obligations are satisfied over time since the customer receives and consumes the benefit as Nasdaq provides the listing service. Upon adoption of Topic 606, the amount of revenue related to the corporate solutions services performance obligation is recognized ratably over a two-year period, which is based on contract terms, with the remaining revenue recognized ratably over time as customers continue to list on our exchanges, which is estimated to be over a period of six years based on our historical listing experience and projected future listing duration.

In the U.S., annual renewal fees are charged based on the number of outstanding shares of companies listed in the U.S. at the end of the prior year and are recognized ratably over the following 12-month period since the customer receives and consumes the benefit as Nasdaq provides the service. European annual renewal fees, which are received from companies listed on our Nasdaq Nordic and Nasdaq Baltic exchanges and Nasdaq First North, are directly related to the listed companies’ market capitalization on a trailing 12-month basis and are recognized ratably over the following 12-month period since the customer receives and consumes the benefit as Nasdaq provides the service.

Market Data Products

Market data products revenues are earned from U.S. and European proprietary market data products. In the U.S., we also earn revenues from U.S. shared tape plans.

We earn revenues primarily based on the number of data subscribers and distributors of our data. Market data products revenues are subscription-based and are recognized on a monthly basis net of amounts due under revenue sharing arrangements with market participants.

For U.S. tape plans, revenues are collected monthly based on published fee schedules and distributed quarterly to the U.S. exchanges based on a formula required by Regulation NMS that takes into account both trading and quoting activity. Revenues are presented on a net basis as we are acting as an agent in this arrangement.

Market Data Products Revenue Sharing

The most significant component of market data products revenues recorded on a net basis is the UTP Plan revenue sharing in the U.S. All indicators of principal versus agent reporting under U.S. GAAP have been considered in analyzing the appropriate presentation of UTP Plan revenue sharing. However, the following are the primary indicators of net reporting:

• We are the administrator for the UTP Plan, in addition to being a participant in the UTP Plan. In our unique role as administrator, we facilitate the collection and dissemination of revenues on behalf of the UTP Plan participants. As a participant, we share in the net distribution of revenues according to the plan on the same terms as all other plan participants.

• The operating committee of the UTP Plan, which is comprised of representatives from each of the participants, including us solely in our capacity as a UTP Plan participant, is responsible for setting the level of fees to be paid by distributors and subscribers and taking action in accordance with the provisions of the UTP Plan, subject to SEC approval.

• Risk of loss on the revenue is shared equally among plan participants according to the UTP Plan.

The exchanges that comprise Nasdaq Nordic and Nasdaq Baltic do not have any market data products revenue sharing agreements.

Index

We develop and license Nasdaq branded indexes, associated derivatives and financial products as part of our Global Index Family. We also provide index data products and custom calculation services for third-party clients. Revenues primarily include license fees from these branded indexes, associated derivatives and financial products in the U.S. and abroad. We primarily have two types of license agreements: transaction-based licenses and asset-based licenses. Transaction-based licenses are generally renewable agreements. Customers are charged based on transaction volume or a minimum contract amount, or both. If a customer is charged based on transaction volume, we recognize revenue when the transaction occurs. If a customer is charged based on a minimum contract amount, we recognize revenue on a pro-rata basis over the licensing term since the customer receives and consumes the benefit as Nasdaq provides the service. Asset-based licenses are also generally renewable agreements. Customers are charged based on a percentage of assets under management for licensed products, per the agreement, on a monthly or quarterly basis. These revenues are recognized over the term of the license agreement since the customer receives and consumes the benefit as Nasdaq provides the service. Revenue from index data subscriptions are recognized on a monthly basis.

Investment Data & Analytics

Investment data & analytics revenues are earned from leading investment content and analytics products. We earn revenues primarily based on the number of content and analytics subscribers and distributors of our content and analytics.

These subscription agreements are generally annual in term, payable in advance, and provide for automatic renewal. Subscription-based revenues are recognized over time on a ratable basis over the contract period beginning on the date that our service is made available to the customer since the customer receives and consumes the benefit as Nasdaq provides the service.

Market Technology

Market Technology provides technology solutions for trading, clearing, settlement, surveillance and information dissemination, as well as risk management solutions. Revenues primarily consist of software, license and support revenues, change request and advisory revenues, and software as a service revenues.

In our Market Technology business, we enter into long-term contracts with customers to develop customized technology solutions, license the right to use software, and provide post-contract support and other services to our customers. We also enter into agreements to modify the system solutions sold by Nasdaq after delivery has occurred. In addition, we enter into subscription agreements which allow customers to connect to our servers to access our software.

Our long-term contracts with customers to develop customized technology solutions, license the right to use software and provide post-contract support and other services to our customers have multiple performance obligations. The performance obligations are generally: 1) software license and installation service and 2) software support. We have determined that the software license and installation service are not distinct as the license and the customized installation service are inputs to produce the combined output, a functional and integrated software system.

For contracts with multiple performance obligations, we allocate the contract transaction price to each performance obligation using our best estimate of the standalone selling price of each distinct good or service in the contract. In instances where standalone selling price is not directly observable, such as when we do not sell the product or service separately, we determine the standalone selling price predominately through an expected cost plus a margin approach.

Contract modifications are routine in the performance of our contracts. Contracts are often modified to account for changes in contract specifications or requirements. In most instances, contract modifications are for goods and services that are not distinct, and, therefore, are accounted for as part of the existing contract.

For our long-term contracts, payments are generally made throughout the contract life and can be dependent on either reaching certain milestones or paid upfront in advance of the service period depending on the stage of the contract. For subscription agreements, contract payment terms can be quarterly, annually or monthly, in advance. For all other contracts, payment terms vary.

We generally recognize revenue over time as our customers simultaneously receive and consume the benefits provided by our performance because our customer controls the asset for which we are creating, our performance does not create an asset with alternative use, and we have a right to payment for performance completed to date. For these services, we recognize revenue over time using costs incurred to date relative to total estimated costs at completion to measure progress toward satisfying our performance obligation. Incurred costs represent work performed, which corresponds with, and thereby depicts, the transfer of control to the customer. Contract costs generally include labor and overhead. For software support and update services, and for subscription agreements which allow customers to connect to our servers to access our software, we generally recognize revenue ratably over the service period beginning on the date our service is made available to the customer since the customer receives and consumes the benefit consistently over the period as Nasdaq provides the services.

Accounting for our long-term contracts requires judgment relative to assessing risks and their impact on the estimate of revenues and costs. Our estimates are impacted by factors such as the potential for schedule and technical issues, productivity, and the complexity of work performed. When adjustments in estimated total contract costs are required, any changes in the estimated revenues from prior estimates are recognized in the current period for the effect of such change. If estimates of total costs to be incurred on a contract exceed estimates of total revenues, a provision for the entire estimated loss on the contract is recorded in the period in which the loss is determined.

Other Revenues

Other revenues include the revenues from the Public Relations Solutions and Digital Media Services businesses which were sold in April 2018. Prior to the sale date, these revenues were included in our Corporate Solutions business and were primarily transaction-based revenues.

Equity Securities

On January 1, 2018, we adopted ASU 2016-01 which requires that investments in equity securities (excluding equity method investments) be measured at fair value with changes in fair value recognized in net income. Equity securities are no longer classified as trading or available for sale.

We elected the measurement alternative for equity securities which were historically accounted for under the cost method of accounting. Since these equity securities do not have readily determinable fair values, they are measured at cost, less any impairment, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. We evaluate these securities for impairment by considering a variety of factors such as the earnings capacity of the investment. If a qualitative assessment indicates that the security is impaired, Nasdaq will estimate the fair value of the security, and if the fair value is less than the carrying amount of the security, recognize an impairment loss in net income equal to the difference between the carrying amount and fair value. There was no impact on our condensed consolidated financial statements as a result of this change.

The guidance for classifying and measuring investments in debt securities is unchanged. Therefore, changes in debt securities classified as trading securities are included in dividend and investment income in the Condensed Consolidated Statements of Income and debt securities classified as available-for-sale investment securities are carried at fair value with unrealized gains and losses, net of tax, reported in accumulated other comprehensive loss within stockholders’ equity in the Condensed Consolidated Balance Sheets. Realized gains and losses on these securities are included in earnings upon disposition of the securities using the specific identification method. In addition, realized losses are recognized when management determines that a decline in value is other than temporary, which requires judgment regarding the amount and timing of recovery. For financial investments that are classified as available-for-sale securities, we also consider the extent to which cost exceeds fair value, the duration of that difference, management’s judgment about the issuer’s current and prospective financial condition, as well as our intent and ability to hold the security until recovery of the unrealized losses.

Business Combinations [Abstract]

Divestiture and Acquisitions

Divestiture and Acquisitions

We completed the following divestiture in 2018 and acquisitions in 2017. Financial results of each transaction are included in our Condensed Consolidated Statements of Income from the date of each divestiture or acquisition.

2018 Divestiture

In April 2018, we sold our Public Relations Solutions and Digital Media Services businesses which were part of our Corporate Solutions business to West Corporation and recognized a pre-tax gain on the sale of $41 million, net of disposal costs ($19 million after tax). The pretax gain is included in gain on divestiture of businesses, net in the Condensed Consolidated Statements of Income for the three and six months ended June 30, 2018.

As of December 31, 2017, the assets and liabilities of the above businesses were held for sale. See Note 5, “Assets and Liabilities Held For Sale,” for further discussion.

Through a multi-year partnership with West, Nasdaq will continue to provide eligible Nasdaq-listed clients with access to public relations, webcasting and webhosting products and services as part of the terms of the transaction.

As part of the terms of the transaction, we will provide transition services to West, such as technology, finance and facilities related services for a period of time, and the compensation received for such transition services will be reflected as a reduction to the underlying expenses incurred by Nasdaq to provide such transition services.

	(in millions)
eVestment	$	744	$	(10	)	$	(104	)	$	405	$	453

The amounts in the table above represent the preliminary allocation of purchase price as of June 30, 2018 and are subject to revision during the remainder of the measurement period, a period not to exceed 12 months from the acquisition date. Adjustments to the provisional values, which may include tax and other estimates, during the measurement period will be recorded in the reporting period in which the adjustment amounts are determined. Changes to amounts recorded as assets and liabilities may result in a corresponding adjustment to goodwill.

See “Intangible Assets” below for further discussion of intangible assets acquired in the eVestment acquisition.

Acquisition of eVestment

In October 2017, we acquired eVestment for $705 million. The aggregate cash consideration of $744 million, which is net of cash acquired of $22 million, included $39 million of estimated tax benefits associated with the transaction. We acquired net liabilities, at fair value, totaling $10 million and we recorded a net deferred tax liability of $104 million, which is net of the $39 million in estimated tax benefits associated with the transaction. The deferred tax liability recorded of $143 million relates to differences in the U.S. GAAP and tax basis of our investment in eVestment. eVestment is part of our Information Services segment.

Nasdaq used cash on hand and issuances of commercial paper to fund this acquisition.

Acquisition of Sybenetix

In September 2017, we acquired Sybenetix for an immaterial amount. Sybenetix is part of our Market Technology segment.

Intangible Assets

The following table presents the details of acquired intangible assets for eVestment at the date of the acquisition. All acquired intangible assets with finite lives are amortized using the straight-line method.

Intangible Assets
($ in millions)
Customer relationships	$	378
Discount rate used	9.3		%
Estimated average useful life	14 years
Trade name	$	13
Discount rate used	9.2		%
Estimated average useful life	8 years
Technology	$	14
Discount rate used	9.2		%
Estimated average useful life	8 years
Total intangible assets	$	405

Customer Relationships

Customer relationships represent the non-contractual and contractual relationships with customers.

Methodology

For our acquisition of eVestment, customer relationships were valued using the income approach, specifically an excess earnings method. The excess earnings method examines the economic returns contributed by the identified tangible and intangible assets of a company, and then isolates the excess return that is attributable to the intangible asset being valued.

Discount Rates

The discount rates used reflect the amount of risk associated with the hypothetical cash flows for the customer relationships relative to the overall business. In developing a discount rate for the customer relationships, we estimated a weighted-average cost of capital for the overall business and we employed this rate when discounting the cash flows. The resulting discounted cash flows were then tax-effected at the applicable statutory rate.

For our acquisition of eVestment, a discounted tax amortization benefit was added to the fair value of the assets under the assumption that the customer relationships would be amortized for tax purposes over a period of 15 years.

Estimated Useful Life

We estimate the useful life based on the historical behavior of the customers and a parallel analysis of the customers using the excess earnings method.

Trade Name

As part of our acquisition of eVestment, we acquired a trade name. This trade name is recognized in the industry and carries a reputation for quality. As such, the reputation and positive recognition embodied in this trade name is a valuable asset to Nasdaq.

Methodology

The eVestment trade name was valued using the income approach, specifically the relief-from-royalty method, or RFRM. The RFRM is used to estimate the cost savings that accrue to the owner of an intangible asset who would otherwise have to pay royalties or license fees on revenues earned through the use of the asset. The royalty rate is applied to the projected revenue over the expected remaining life of the intangible asset to estimate royalty savings. The net after-tax royalty savings are calculated for each year in the remaining economic life of the trade name and discounted to present value.

The discount rate used reflects the amount of risk associated with the hypothetical cash flows for the trade name relative to the overall business as discussed above in “Customer Relationships.”

We have estimated the useful life of the eVestment trade name to be 8 years.

Technology

As part of our acquisition of eVestment, we acquired developed technology.

Methodology

The developed technology was valued using the income approach, specifically the RFRM as discussed above in “Trade Names.”

Discount rate

The discount rate used reflects the amount of risk associated with the hypothetical cash flows for the developed technology relative to the overall business as discussed above in “Customer Relationships.”

Estimated Useful Life

We have estimated the useful life of the eVestment technology to be 8 years.

Pro Forma Results and Acquisition-related Costs

The condensed consolidated financial statements for the three and six months ended June 30, 2018 and 2017 include the financial results of the above 2017 acquisitions from the date of each acquisition. Pro forma financial results have not been presented since these acquisitions both individually and in the aggregate were not material to our financial results.

Acquisition-related costs for the transactions described above were expensed as incurred and are included in merger and strategic initiatives expense in the Condensed Consolidated Statements of Income.

Assets and Liabilities Held For Sale

Discontinued Operations and Disposal Groups [Abstract]

Assets and Liabilities Held For Sale

Assets and Liabilities Held For Sale

In September 2017, we commenced a process to evaluate strategic alternatives for our Public Relations Solutions and Digital Media Services businesses within our Corporate Solutions business as part of our strategic refinement and subsequently committed to a plan to divest these businesses. The Corporate Solutions business is part of our Corporate Services segment. The Public Relations Solutions and Digital Media Services businesses included the following products and services:

• Nasdaq GlobeNewswire;

• Nasdaq Influencers;

• Nasdaq Media Intelligence;

• Nasdaq IR Websites and Newsrooms; and

• Nasdaq Webcasts.

We determined that we met all of the criteria to classify the assets and liabilities of these businesses as held for sale. The disposal of these businesses did not represent a strategic shift that would have a major effect on our operations and financial results and were, therefore, not classified as discontinued operations. As a result of this classification, the assets and liabilities of these businesses were separately presented within the Condensed Consolidated Balance Sheets as held for sale and were recorded at the lower of their carrying amount or fair value less costs to sell.

In January 2018, we entered into a definitive agreement to sell the above businesses for $335 million, subject to post-closing adjustments and, in April 2018, we completed the sale and recognized a pre-tax gain on the sale of $41 million, net of disposal costs ($19 million after tax). See “2018 Divestiture,” of Note 4, “Divestiture and Acquisitions,” for further discussion.

Based on the sales price in the agreement, no impairment charge was recorded at the time of the sale as the carrying amount of the net assets was less than the sales price in the agreement less costs to sell.

The carrying amounts of the major classes of assets and liabilities that were classified as held for sale at December 31, 2017 in the Condensed Consolidated Balance Sheets were as follows:

	December 31, 2017
	(in millions)
Receivables, net	$	27
Property and equipment, net	21
Goodwill (1)	202
Intangible assets, net(2)	38
Other assets	9
Total assets held for sale	$	297
Deferred tax liabilities	$	16
Other current liabilities	29
Total liabilities held for sale	$	45

⁽¹⁾  The assignment of goodwill was based on the relative fair value of the disposal group and the portion of the remaining reporting unit.

⁽¹⁾Concurrent with the realignment of our BWise corporate enterprise risk management solutions from our Market Technology segment to our Corporate Services segment, goodwill was reassigned to the Corporate Services segment using a relative fair value approach.

As of June 30, 2018, the amount of goodwill that is expected to be deductible for tax purposes in future periods is $763 million.

Goodwill represents the excess of purchase price over the value assigned to the net assets, including identifiable intangible assets, of a business acquired. Goodwill is allocated to our reporting units based on the assignment of the fair values of each reporting unit of the acquired company. We test goodwill for impairment at the reporting unit level annually, or in interim periods if certain events occur indicating that the carrying amount may be impaired, such as changes in the business climate, poor indicators of operating performance or the sale or disposition of a significant portion of a reporting unit. There was no impairment of goodwill for the six months ended June 30, 2018 and 2017; however, events such as extended economic weakness or unexpected significant declines in operating results of a reporting unit may result in goodwill impairment charges in the future.

Amortization expense for acquired finite-lived intangible assets was $28 million for the three months ended June 30, 2018, $22 million for the three months ended June 30, 2017, $56 million for the six months ended June 30, 2018, and $45 million for the six months ended June 30, 2017. Amortization expense increased in 2018 primarily due to additional amortization expense associated with acquired intangible assets in 2017. These amounts are included in depreciation and amortization expense in the Condensed Consolidated Statements of Income.

The estimated future amortization expense (excluding the impact of foreign currency translation adjustments of $84 million as of June 30, 2018) of acquired finite-lived intangible assets as of June 30, 2018 is as follows:

Financial Investments, at Fair Value

Trading Securities

Trading securities, which are included in financial investments, at fair value in the Condensed Consolidated Balance Sheets, are primarily comprised of highly rated European government debt securities, of which $153 million as of June 30, 2018 and $160 million as of December 31, 2017, are assets utilized to meet regulatory capital requirements, primarily for our clearing operations at Nasdaq Clearing.

Available-for-Sale Investment Securities

As of June 30, 2018 and December 31, 2017, available-for-sale investment securities, which are included in financial investments, at fair value in the Condensed Consolidated Balance Sheets, are primarily comprised of commercial paper debt securities. As of June 30, 2018 and December 31, 2017, the cumulative unrealized gains and losses on these securities were immaterial.

Equity Method Investments

As of June 30, 2018 and December 31, 2017, our equity method investments primarily included equity interests in OCC and EuroCCP N.V.

The carrying amounts of our equity method investments are included in other non-current assets in the Condensed Consolidated Balance Sheets.

Net income recognized from our equity interest in the earnings and losses of these equity method investments was $5 million for the three months ended June 30, 2018, $2 million for the three months ended June 30, 2017, $7 million for the six months ended June 30, 2018, and $6 million for the six months ended June 30, 2017.

Capital Contribution to OCC

In March 2015, OCC implemented a capital plan under which the options exchanges that are OCC’s stockholders contributed $150 million of new equity capital to OCC, committed to make future replenishment capital contributions under certain circumstances, and received commitments regarding future dividend payments and related matters. See “Other Commitments,” of Note 16, “Commitments, Contingencies and Guarantees,” for further discussion of our commitment to make future replenishment capital contributions. Nasdaq and ISE each contributed $30 million of new equity capital under the OCC capital plan. OCC adopted specific policies with respect to fees, customer refunds and stockholder dividends, which envision an annual dividend equal to the portion of OCC’s after-tax income that exceeds OCC’s capital requirements after payment of refunds to OCC’s clearing members (such refunds are generally 50% of the portion of OCC’s pre-tax income that exceeds OCC’s capital requirements). In February 2016, the SEC approved the OCC capital plan and certain industry participants appealed that approval in the Federal Court Of Appeals. The Court of Appeals denied a requested stay, permitting OCC to pay a dividend which Nasdaq received in February 2016. In August 2017, the Court of Appeals remanded the case to the SEC for further examination of the record and an independent assessment by the SEC of the evidence OCC submitted. The Court directed that the SEC approval of the OCC capital plan remain in place during the SEC’s examination unless the SEC determined not to preserve it. The SEC has allowed OCC to preserve the capital plan, and in September 2017, OCC disbursed an annual dividend. Nasdaq, as the owner of two shares, received $10 million. There has been no final ruling by the SEC at this time, and there is no deadline for the SEC to issue its ruling.

Equity Securities 

The carrying amounts of our equity securities are included in other non-current assets in the Condensed Consolidated Balance Sheets. As of June 30, 2018, our equity securities primarily represent our 5% ownership interest in LCH.Clearnet Group Limited. As of December 31, 2017, our equity securities primarily represented our 5% ownership in Borsa Istanbul and our 5% ownership interest in LCH.Clearnet Group Limited. For the six months ended June 30, 2018, no impairment charges were recorded on our equity securities and there were no upward or downward adjustments recorded.

The Borsa Istanbul shares, which were issued to us in the first quarter of 2014, were part of the consideration received under a market technology agreement. This investment had a carrying amount of $75 million which was guaranteed to us via a put option negotiated as part of the market technology agreement. During the second quarter of 2018, we exercised theput option and we expect to receive cash consideration in installments through 2022.

⁽¹⁾Concurrent with the realignment of our BWise corporate enterprise risk management solutions from our Market Technology segment to our Corporate Services segment, deferred revenue was reassigned to the Corporate Services segment.

⁽²⁾Other revenues include the revenues from the Public Relations Solutions and Digital Media Services businesses through the date of sale (April 2018). See “2018 Divestiture,” of Note 4, “Divestiture and Acquisitions,” to the condensed consolidated financial statements for further discussion.

⁽³⁾ Other primarily includes revenues from listing of additional shares fees which are included in our Listing Services business.

On January 1, 2018, we adopted Topic 606. As a result, a portion of revenues that were previously deferred were recognized either in prior period revenues, through restatement, or as an adjustment to retained earnings upon adoption of the new standard. See “Revenue From Contracts With Customers,” of Note 3, “Significant Accounting Policies Update,” for a description of our initial listing, annual listing, market technology, corporate solutions, and information services revenues and the revenue recognition policy for each of these revenue streams.

* * * * * *

As of June 30, 2018, we estimate that our deferred revenue will be recognized in the following years:

Commercial Paper Program

Our U.S. dollar commercial paper program is supported by our 2017 Credit Facility which provides liquidity support for the repayment of commercial paper issued through the commercial paper program. See “2017 Credit Facility” below for further discussion of our 2017 Credit Facility. The effective interest rate of commercial paper issuances fluctuate as short term interest rates and demand fluctuate. The fluctuation of these rates due to market conditions may impact our interest expense.

As of June 30, 2018, commercial paper notes in the table above reflect the aggregate principal amount, less the unamortized discount which is being accreted through interest expense over the life of the applicable notes. The original maturities of these notes range from 10 days to 62 days and the weighted-average maturity is 28 days. The weighted-average effective interest rate is 2.46% per annum.

Senior Unsecured Notes

Our senior unsecured notes were all issued at a discount. As a result of the discount, the proceeds received from each issuance were less than the aggregate principal amount. As of June 30, 2018, the amounts in the table above reflect the aggregate principal amount, less the unamortized debt discount and the unamortized debt issuance costs which are being accreted through interest expense over the life of the applicable notes. Our senior unsecured notes are general unsecured obligations of ours and rank equally with all of our existing and future unsubordinated obligations and they are not guaranteed by any of our subsidiaries. The senior unsecured notes were issued under indentures that, among other things, limit our ability to consolidate, merge or sell all or substantially all of our assets, create liens, and enter into sale and leaseback transactions.

With the exception of the 2020 Notes, upon a change of control triggering event (as defined in the various note indentures), the terms require us to repurchase all or part of each holder’s notes for cash equal to 101% of the aggregate principal amount purchased plus accrued and unpaid interest, if any.

Senior Unsecured Floating Rate Notes

In September 2017, Nasdaq issued the 2019 Notes. The 2019 Notes pay interest quarterly in arrears at a rate equal to the three-month U.S. dollar LIBOR as determined at the beginning of each quarterly period plus 0.39% per annum until March 22, 2019.

5.55% Senior Unsecured Notes

In January 2010, Nasdaq issued the 2020 Notes. The 2020 Notes pay interest semiannually at a rate of 5.55% per annum until January 15, 2020.

3.875% Senior Unsecured Notes

In June 2013, Nasdaq issued the 2021 Notes. The 2021 Notes pay interest annually at a rate of 3.875% per annum until June 7, 2021 and such rate may vary with Nasdaq’s debt rating up to a rate not to exceed 5.875%.

The 2021 Notes have been designated as a hedge of our net investment in certain foreign subsidiaries to mitigate the foreign exchange risk associated with certain investments in these subsidiaries. The decrease in the carrying amount of $18 million noted in the “Payments, Accretion and Other” column in the table above primarily reflects the translation of the 2021 Notes into U.S. dollars and is recorded in accumulated other comprehensive loss within stockholders’ equity in the Condensed Consolidated Balance Sheets as of June 30, 2018.

4.25% Senior Unsecured Notes

In May 2014, Nasdaq issued the 2024 Notes. The 2024 Notes pay interest semiannually at a rate of 4.25% per annum until June 1, 2024 and such rate may vary with Nasdaq’s debt rating up to a rate not to exceed 6.25%.

1.75% Senior Unsecured Notes

In May 2016, Nasdaq issued the 2023 Notes. The 2023 Notes pay interest annually at a rate of 1.75% per annum until May 19, 2023 and such rate may vary with Nasdaq’s debt rating up to a rate not to exceed 3.75%.

The 2023 Notes have been designated as a hedge of our net investment in certain foreign subsidiaries to mitigate the foreign exchange rate risk associated with certain investments in these subsidiaries. The decrease in the carrying amount of $18 million noted in the “Payments, Accretion and Other” column in the table above reflects the translation of the 2023 Notes into U.S. dollars and is recorded in accumulated other comprehensive loss within stockholders’ equity in the Condensed Consolidated Balance Sheets as of June 30, 2018.

3.85% Senior Unsecured Notes

In June 2016, Nasdaq issued the 2026 Notes. The 2026 Notes pay interest semiannually at a rate of 3.85% per annum until June 30, 2026 and such rate may vary with Nasdaq’s debt rating up to a rate not to exceed 5.85%.

Credit Facilities

As of June 30, 2018, the amounts in the table above reflect the aggregate principal amount, less the unamortized debt issuance costs which are being accreted through interest expense over the life of the applicable credit facility. Nasdaq is permitted to repay borrowings under our credit facilities at any time in whole or in part, without penalty.

Our credit facilities contain financial and operating covenants. Financial covenants include a minimum interest expense coverage ratio and a maximum leverage ratio. Operating covenants include, among other things, limitations on Nasdaq’s ability to incur additional indebtedness, grant liens on assets, dispose of assets and pay dividends. Our credit facilities allow us to pay cash dividends on our common stock. The facilities also contain customary affirmative covenants, including access to financial statements, notice of defaults and certain other material events, maintenance of properties and insurance, and events of default, including cross-defaults to our material indebtedness.

2017 Credit Facility

In April 2017, Nasdaq entered into the 2017 Credit Facility. The 2017 Credit Facility consists of a $1 billionfive-year revolving credit facility (with sublimits for non-dollar borrowings, swingline borrowings and letters of credit), which replaced a former credit facility. Nasdaq intends to use funds available under the 2017 Credit Facility for general corporate purposes and to provide liquidity support for the repayment of commercial paper issued through the commercial paper program.

As of June 30, 2018, no amounts were outstanding on the 2017 Credit Facility. The $4 million credit balance represents unamortized debt issuance costs. Of the $1 billion that is available for borrowing, $271 million provides liquidity support for the commercial paper program and for a letter of credit. As such, as of June 30, 2018, the total remaining amount available under the 2017 Credit Facility was $729 million. See “Commercial Paper Program” above for further discussion of our commercial paper program.

Under our 2017 Credit Facility, borrowings under the revolving credit facility and swingline borrowings bear interest on the principal amount outstanding at a variable interest rate based on either the LIBOR or the base rate (as defined in the credit agreement) (or other applicable rate with respect to non-dollar borrowings), plus an applicable margin that varies with Nasdaq’s debt rating.

The 2017 Credit Facility includes an option for Nasdaq to increase the available aggregate amount by up to $500 million, subject to the consent of the lenders funding the increase and certain other conditions.

2016 Credit Facility

In March 2016, Nasdaq entered into the 2016 Credit Facility. Under our 2016 Credit Facility, borrowings bear interest on the principal amount outstanding at a variable interest rate based on either the LIBOR or the base rate (or other applicable rate with respect to non-dollar borrowings), plus an applicable margin that varies with Nasdaq’s debt rating.

As of June 30, 2018, the amount outstanding of $100 million is due upon maturity at November 25, 2019.

Other Credit Facilities

We also have credit facilities related to our Nasdaq Clearing operations in order to provide further liquidity. Credit facilities, which are available in multiple currencies, totaled $218 million as of June 30, 2018 and $187 million as of December 31, 2017 in available liquidity, none of which was utilized.

Debt Covenants

As of June 30, 2018, we were in compliance with the covenants of all of our debt obligations.

Defined Contribution Savings Plan

We sponsor a 401(k) Plan for U.S. employees. Employees are immediately eligible to make contributions to the plan and are also eligible for an employer contribution match at an amount equal to 100.0% of the first 6.0% of eligible employee contributions. Savings plan expense included in compensation and benefits expense in the Condensed Consolidated Statements of Income was $3 million for both the three months ended June 30, 2018 and 2017 and $7 million for both the six months ended June 30, 2018 and 2017.

Pension and Supplemental Executive Retirement Plans

We maintain non-contributory, defined-benefit pension plans, non-qualified SERPs for certain senior executives and other post-retirement benefit plans for eligible employees in the U.S., collectively referred to as the Nasdaq Benefit Plans. Our pension plans and SERPs are frozen. Future service and salary for all participants do not count toward an accrual of benefits under the pension plans and SERPs. Most employees outside the U.S. are covered by local retirement plans or by applicable social laws. Benefits under social laws are generally expensed in the periods in which the costs are incurred. The total expense for these plans is included in compensation and benefits expense in the Condensed Consolidated Statements of Income and was $5 million for the three months June 30, 2018, $4 million for the three months ended June 30, 2017, $11 million for the six months June 30, 2018, and $8 million for the six months ended June 30, 2017.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]

Share-Based Compensation

Share-Based Compensation

We have a share-based compensation program that provides our board of directors broad discretion in creating employee equity incentives. Share-based awards granted under this program include stock options, restricted stock (consisting of restricted stock units), and PSUs. For accounting purposes, we consider PSUs to be a form of restricted stock.

Summary of Share-Based Compensation Expense

The following table shows the total share-based compensation expense resulting from equity awards and the 15.0% discount for the ESPP for the three and six months ended June 30, 2018 and 2017 in the Condensed Consolidated Statements of Income:

	Three Months Ended June 30,						Six Months Ended June 30,

Share-based compensation expense before income taxes	$	18		$	19		$	33		$	34
Income tax benefit	(5		)	(8		)	(9		)	(14		)
Share-based compensation expense after income taxes	$	13		$	11		$	24		$	20

Common Shares Available Under Our Equity Plan

As of June 30, 2018, we had approximately 10.9 million shares of common stock authorized for future issuance under our Equity Plan.

Restricted Stock

We grant restricted stock to most active employees. The grant date fair value of restricted stock awards is based on the closing price at the date of grant less the present value of future cash dividends. Restricted stock awards granted generally vest 25.0% on the second anniversary of the grant date, 25.0% on the third anniversary of the grant date, and 50.0% on the fourth anniversary of the grant date. We generally recognize compensation expense for restricted stock awards on a straight-line basis over the requisite service period of the award, taking into account an estimated forfeiture rate.

Summary of Restricted Stock Activity

The following table summarizes our restricted stock activity for the six months ended June 30, 2018:

	Restricted Stock
	Number of Awards		Weighted-Average Grant Date Fair Value
Unvested balances at January 1, 2018	1,988,500		$	57.34
Granted	484,750		$	81.69
Vested	(646,994	)	$	46.87
Forfeited	(191,365	)	$	62.09
Unvested balances at June 30, 2018	1,634,891		$	68.15

As of June 30, 2018, $64 million of total unrecognized compensation cost related to restricted stock is expected to be recognized over a weighted-average period of 1.9 years.

PSUs

The grant date fair value of PSUs is based on the closing price at the date of grant less the present value of future cash dividends. PSUs are based on performance measures that impact the amount of shares that each recipient will receive upon vesting. We report the target number of PSUs granted, unless we have determined that it is more likely than not, based on the actual achievement of performance measures, that an employee will receive a different amount of shares underlying the PSUs, in which case we report the amount of shares the employee is likely to receive. We have two performance-based long-term PSU programs for certain officers, a one-year performance-based program and a three-year cumulative performance-based program that focuses on TSR.

One-Year PSU Program

Under the one-year performance-based program, an employee may receive from 0.0% to 150.0% of the target amount granted, depending on the achievement of performance measures. These awards vest ratably on an annual basis over a three-year period commencing with the end of the one-year performance period. Compensation cost is recognized over the performance period and the three-year vesting period, taking into account an estimated forfeiture rate.

During 2017, certain grants of PSUs with a one-year performance period exceeded the applicable performance parameters. As a result, an additional 14,497 units above target were considered granted in the first quarter of 2018 and are included in the below table.

Three-Year PSU Program

Under the three-year performance-based program, each individual receives PSUs with a three-year cumulative performance period that vest at the end of the performance period. Compensation cost is recognized over the three-year vesting period. Performance will be determined by comparing Nasdaq’s TSR to two peer groups, each weighted 50.0%. The first peer group consists of exchange companies, and the second peer group consists of all companies in the S&P 500. Nasdaq’s relative performance ranking against each of these groups will determine the final number of shares delivered to each individual under the program. The payout under this program will be between 0.0% and 200.0% of the number of PSUs granted and will be determined by Nasdaq’s overall performance against both peer groups. However, if Nasdaq’s TSR is negative for the three-year performance period, regardless of TSR ranking, the payout will not exceed 100.0% of the number of PSUs granted. We estimate the fair value of PSUs granted under the three-year PSU program using the Monte Carlo simulation model, as these awards contain a market condition.

Certain grants of PSUs that were issued in 2015 with a three-year performance period exceeded the applicable performance parameters. As a result, an additional 237,876 units above target were considered granted in the first quarter of 2018 and are included in the below table.

The following weighted-average assumptions were used to determine the weighted-average fair values of the PSU awards granted under the three-year PSU program for the six months ended June 30, 2018 and 2017:

	Six Months Ended June 30,
	2018		2017
Weighted-average risk free interest rate(1)	2.36	%	1.44	%
Expected volatility(2)	18.7	%	19.2	%
Weighted-average grant date share price	$86.24		$69.45
Weighted-average fair value at grant date	$116.86		$81.57

____________

⁽¹⁾  The risk-free interest rate for periods within the expected life of the award is based on the U.S. Treasury yield curve in effect at the time of grant.

⁽²⁾  We use historic volatility for PSU awards issued under the three-year PSU program, as implied volatility data could not be obtained for all the companies in the peer groups used for relative performance measurement within the program.

In addition, the annual dividend assumption utilized in the Monte Carlo simulation model is based on Nasdaq’s dividend yield at the date of grant.

Summary of PSU Activity

The following table summarizes our PSU activity for the six months ended June 30, 2018:

	PSUs
	One-Year Program				Three-Year Program
	Number of Awards		Weighted-Average Grant Date Fair Value		Number of Awards		Weighted-Average Grant Date Fair Value
Unvested balances at January 1, 2018	333,004		$	61.39	1,009,958		$	78.18
Granted	131,185		$	80.29	484,075		$	90.92

Unvested balances at June 30, 2018	435,450		$	67.30	838,829		$	96.55

As of June 30, 2018, $13 million of total unrecognized compensation cost related to the one-year PSU program is expected to be recognized over a weighted-average period of 1.5 years. For the three-year PSU program, $40 million of total unrecognized compensation cost is expected to be recognized over a weighted-average period of 1.6 years.

The fair value of stock options is estimated using the Black-Scholes option-pricing model. Each grant has a 10-year life. In

January 2017, our CEO received 268,817 performance-based

non-qualified stock options which will vest annually over a three-year period, with each vesting contingent upon the achievement of annual performance parameters. On January 30, 2018, Nasdaq's management compensation committee and board of directors determined that the performance goal for 2017 was met, resulting in the settlement of the first one-third of the grant. There were no stock option awards granted during the six months ended June 30, 2018.

Summary of Stock Option Activity

A summary of stock option activity for the six months ended June 30, 2018 is as follows:

	Number of Stock Options		Weighted-Average Exercise Price		Weighted-Average Remaining Contractual Term (in years)	Aggregate Intrinsic Value (in millions)
Outstanding at January 1, 2018	571,380		$	43.84	5.40	$	19
Exercised	(88,000	)	24.51
Forfeited	(954	)	34.53
Outstanding at June 30, 2018	482,426		$	47.38	5.61	$	21
Exercisable at June 30, 2018	303,214		$	35.98	3.96	$	17

We received net cash proceeds of $1 million from the exercise of 53,805 stock options for the three months ended June 30, 2018 and received net cash proceeds of $2 million from the exercise of 88,000 stock options for the six months ended June 30, 2018. We received net cash proceeds of $21 million from the exercise of 993,745 stock options for the three months ended June 30, 2017 and received net cash proceeds of $22 million from the exercise of 1,034,161 stock options for the six months ended June 30, 2017.

The aggregate intrinsic value in the above table represents the total pre-tax intrinsic value (i.e., the difference between our closing stock price on June 29, 2018 of $91.27 and the exercise price, times the number of shares) based on stock options with an exercise price less than Nasdaq’s closing price of $91.27 as of June 29, 2018, which would have been received by the option holders had the option holders exercised their stock options on that date. This amount can change based on the fair market value of our common stock. The total number of in-the-money stock options exercisable as of June 30, 2018 was 0.3 million and the weighted-average exercise price was $35.98. As of June 30, 2017, 0.4 million outstanding stock options were exercisable and the weighted-average exercise price was $23.98. 

The total pre-tax intrinsic value of stock options exercised was $4 million for the three months ended June 30, 2018, $49 million for the three months ended June 30, 2017, $6 million for the six months ended June 30, 2018, and $51 million for the six months ended June 30, 2017. 

ESPP

We have an ESPP under which approximately 2.0 million shares of our common stock have been reserved for future issuance as of June 30, 2018. Under our ESPP, employees may purchase shares having a value not exceeding 10.0% of their annual compensation, subject to applicable annual Internal Revenue Service limitations. We record compensation expense related to the 15.0% discount that is given to our employees which totaled $1 million for both the three months ended June 30, 2018 and 2017 and $2 million for both the six months ended June 30, 2018 and 2017.

Nasdaq Stockholders' Equity

NasdaqStockholders’ Equity

Common Stock

As of June 30, 2018, 300,000,000 shares of our common stock were authorized, 169,968,175 shares were issued and 164,503,404 shares were outstanding. The holders of common stock are entitled to one vote per share, except that our certificate of incorporation limits the ability of any person to vote in excess of 5.0% of the then-outstanding shares of Nasdaq common stock.

Common Stock in Treasury, at Cost

We account for the purchase of treasury stock under the cost method with the shares of stock repurchased reflected as a reduction to Nasdaq stockholders’ equity and included in common stock in treasury, at cost in the Condensed Consolidated Balance Sheets. Shares repurchased under our share repurchase program are currently retired and canceled. When treasury shares are reissued, they are recorded at the average cost of the treasury shares acquired. We held 5,464,771 shares of common stock in treasury as of June 30, 2018 and 4,932,402 shares as of December 31, 2017, most of which are related to shares of our common stock repurchased for the settlement of employee tax withholding obligations arising from the vesting of restricted stock.

Share Repurchase Program

In January 2018, our board of directors authorized an additional $500 million for the share repurchase program bringing the total capacity to $726 million.

These purchases may be made from time to time at prevailing market prices in open market purchases, privately-negotiated transactions, block purchase techniques or otherwise, as determined by our management. The purchases are primarily funded from existing cash balances. The share repurchase program may be suspended, modified or discontinued at any time. The share repurchase program has no defined expiration date.

The following table summarizes our share repurchase activity:

	Six Months Ended June 30,
	2018		2017
Number of shares of common stock repurchased	3,929,520		2,215,755
Average price paid per share	$	86.58	$	70.64
Total purchase price (in millions)	$	340	$	156

As discussed above in “Common Stock in Treasury, at Cost,” shares repurchased under our share repurchase program are currently retired and cancelled. As of June 30, 2018, the remaining amount authorized for share repurchases under the program was $386 million.

Other Repurchases of Common Stock

During the first six months of 2018, we repurchased 532,369 shares of our common stock in settlement of employee tax withholding obligations arising from the vesting of restricted stock.

Preferred Stock

Our certificate of incorporation authorizes the issuance of 30,000,000 shares of preferred stock, par value $0.01 per share, issuable from time to time in one or more series. As of June 30, 2018 and December 31, 2017, no shares of preferred stock were issued or outstanding.

Cash Dividends on Common Stock

During the six months ended June 30, 2018, our board of directors declared the following cash dividends:

Declaration Date	Dividend Per Common Share		Record Date	Total Amount Paid		Payment Date
				(in millions)
January 30, 2018	$	0.38	March 16, 2018	$	63	March 30, 2018
March 26, 2018	0.44		June 15, 2018	73		June 29, 2018
				$	136

The total amount paid of $136 million was recorded in retained earnings in the Condensed Consolidated Balance Sheets at June 30, 2018.

In July 2018, the board of directors declared a regular quarterly cash dividend of $0.44 per share on our outstanding common stock. The dividend is payable on September 28, 2018 to shareholders of record at the close of business on September 14, 2018. The estimated amount of this dividend is $72 million. In March 2018, the board of directors declared a regular quarterly cash dividend of $0.44 per share on our outstanding common stock which reflects a 16.0% increase from our prior quarterly cash dividend of $0.38. Future declarations of quarterly dividends and the establishment of future record and payment dates are subject to approval by the board of directors.

Our board of directors maintains a dividend policy with the intention to provide stockholders with regular and growing dividends over the long term as earnings and cash flow grow.

Fair Value Disclosures [Abstract]

Fair Value of Financial Instruments

Fair Value of Financial Instruments

The following tables present our financial assets that are measured at fair value on a recurring basis as of June 30, 2018 and December 31, 2017. We did not have any financial liabilities measured at fair value on a recurring basis as of June 30, 2018 and December 31, 2017.

	June 30, 2018
	Total		Level 1		Level 2		Level 3
	(in millions)
Financial investments, at fair value	$	313	$	128	$	185	$	—

Default fund and margin deposit investments	2,129		371		1,758		—
Total	$	2,364	$	506	$	1,858	$	—

As of June 30, 2018 and December 31, 2017, Level 1 financial investments, at fair value were primarily comprised of trading securities, mainly highly rated European government debt securities. As of June 30, 2018 and December 31, 2017, Level 2 financial investments, at fair value were primarily comprised of trading securities, mainly time deposits, corporate bonds and European mortgage bonds. Of the Level 1 and Level 2 financial investments, at fair value, $153 million as of June 30, 2018 and $160 million as of December 31, 2017 are assets utilized to meet regulatory capital requirements, primarily for our clearing operations at Nasdaq Clearing.

Our Level 1 default fund and margin deposit investments were primarily comprised of highly rated European government debt securities. Level 2 default fund and margin deposit investments were primarily comprised of central bank certificates and reverse repurchase agreements, as of June 30, 2018 and December 31, 2017.

See Note 15, “Clearing Operations,” for further discussion of default fund contributions and margin deposits.

There were no transfers between Level 1 and Level 2 of the fair value hierarchy as of June 30, 2018 and December 31, 2017. 

Financial Instruments Not Measured at Fair Value on a Recurring Basis

Some of our financial instruments are not measured at fair value on a recurring basis but are recorded at amounts that approximate fair value due to their liquid or short-term nature. Such financial assets and financial liabilities include: cash and cash equivalents, restricted cash, receivables, net, certain other current assets, accounts payable and accrued expenses, Section 31 fees payable to SEC, accrued personnel costs, commercial paper and certain other current liabilities.

Our investments in OCC and EuroCCP N.V. are accounted for under the equity method of accounting. Our investment in LCH.Clearnet Group Limited is accounted for using the measurement alternative as this investment does not have a readily determinable fair value. See “Equity Securities,” of Note 3, “Significant Accounting Policies Update,” and “Equity Method Investments,” and “Equity Securities,” of Note 7, “Investments,” for further discussion.

We also consider our debt obligations to be financial instruments. The fair value of our debt obligations, utilizing discounted cash flow analyses for our floating rate debt and prevailing market rates for our fixed rate debt, was $4.0 billion as of June 30, 2018 and $4.4 billion as of December 31, 2017. The discounted cash flow analyses are based on borrowing rates currently available to us for debt with similar terms and maturities. The fair value of our commercial paper approximates the carrying value since the rates of interest on this short-term debt approximate market rates as of June 30, 2018. Our commercial paper and our fixed rate and floating rate debt are categorized as Level 2 in the fair value hierarchy.

For further discussion of our debt obligations, see Note 9, “Debt Obligations.”

Non-Financial Assets Measured at Fair Value on a Non-Recurring Basis

Our non-financial assets, which include goodwill, intangible assets, and other long-lived assets, are not required to be carried at fair value on a recurring basis. Fair value measures of non-financial assets are primarily used in the impairment analysis of these assets. Any resulting asset impairment would require that the non-financial asset be recorded at its fair value. Nasdaq uses Level 3 inputs to measure the fair value of the above assets on a non-recurring basis. As of June 30, 2018 and December 31, 2017, there were no non-financial assets measured at fair value on a non-recurring basis.

Clearing Operations

Due to and from Broker-Dealers and Clearing Organizations [Abstract]

Clearing Operations

Clearing Operations

NasdaqClearing

Nasdaq Clearing is authorized and supervised under EMIR as a multi-asset clearinghouse by the SFSA and is authorized to conduct clearing operations in Norway by the Norwegian Ministry of Finance. The clearinghouse acts as the CCP for exchange and OTC trades in equity derivatives, fixed income derivatives, resale and repurchase contracts, power derivatives, emission allowance derivatives, freight and fuel oil derivatives, and seafood derivatives. 

Through our clearing operations in the financial markets, which include the resale and repurchase market, the commodities markets, and the seafood market, Nasdaq Clearing is the legal counterparty for, and guarantees the fulfillment of, each contract cleared. These contracts are not used by Nasdaq Clearing for the purpose of trading on its own behalf. As the legal counterparty of each transaction, Nasdaq Clearing bears the counterparty risk between the purchaser and seller in the contract. In its guarantor role, Nasdaq Clearing has precisely equal and offsetting claims to and from clearing members on opposite sides of each contract, standing as the CCP on every contract cleared. In accordance with the rules and regulations of Nasdaq Clearing, clearing members’ open positions are aggregated to create a single portfolio for which default fund and margin collateral requirements are calculated. See “Default Fund Contributions and Margin Deposits” below for further discussion of Nasdaq Clearing’s default fund and margin requirements.

Nasdaq Clearing maintains four member sponsored default funds: one related to financial markets, one related to commodities markets, one related to the seafood market, and a mutualized fund. Under this structure, Nasdaq Clearing and its clearing members must contribute to the total regulatory capital related to the clearing operations of Nasdaq Clearing. This structure applies an initial separation of default fund contributions for the financial, commodities and seafood markets in order to create a buffer for each market’s counterparty risks. Simultaneously, a mutualized default fund provides capital efficiencies to Nasdaq Clearing’s members with regard to total regulatory capital required. See “Default Fund Contributions” below for further discussion of Nasdaq Clearing’s default fund. Power of assessment and a liability waterfall also have been implemented. See “Power of Assessment” and “Liability Waterfall” below for further discussion. These requirements ensure the alignment of risk between Nasdaq Clearing and its clearing members.

Default Fund Contributions and Margin Deposits

As of June 30, 2018, clearing member default fund contributions and margin deposits were as follows:

	June 30, 2018
	Cash Contributions		Non-Cash Contributions		Total Contributions
	(in millions)
Default fund contributions	$	427	$	132	$	559
Margin deposits	4,014		4,038		8,052
Total	$	4,441	$	4,170	$	8,611

In accordance with its investment policy, of the total cash contributions of $4,441 million, Nasdaq Clearing has invested $913 million in highly rated European and U.S. government debt securities or central bank certificates with maturity dates primarily 90 days or less and $694 million in reverse repurchase agreements secured with highly rated government securities with maturity dates that range from 3 days to 22 days. The carrying value of these securities approximates their fair value due to the short-term nature of the instruments and reverse repurchase agreements. The remainder of this balance was held in cash in demand deposit accounts at central banks and large, highly rated financial institutions. Of the total default fund contributions of $559 million, Nasdaq Clearing can utilize $489 million as capital resources in the event of a counterparty default. The remaining balance of $70 million pertains to member posted surplus balances.

In the investment activity related to default fund and margin contributions, we are exposed to counterparty risk related to reverse repurchase agreement transactions, which reflect the risk that the counterparty might become insolvent and, thus, fail to meet its obligations to our clearinghouse. We mitigate this risk by only engaging in transactions with high credit quality reverse repurchase agreement counterparties and by limiting the acceptable collateral under the reverse repurchase agreement to high quality issuers, primarily government securities and other securities explicitly guaranteed by a government. The value of the underlying security is monitored during the lifetime of the contract and in the event the market value of the underlying security falls below the reverse repurchase amount our clearinghouse requires additional collateral or a reset of the contract.

Default Fund Contributions

Contributions made to the default funds are proportional to the exposures of each clearing member. When a clearing member is active in more than one market, contributions must be made to all markets’ default funds in which the member is active. Clearing members’ eligible contributions may include cash and non-cash contributions. Cash contributions received are held in cash or invested by Nasdaq Clearing, in accordance with its investment policy, either in highly rated government debt securities, time deposits, central bank certificates or reverse repurchase agreements with highly rated government debt securities as collateral. Nasdaq Clearing maintains and manages all cash deposits related to margin collateral. All risks and rewards of collateral ownership, including interest, belong to Nasdaq Clearing. Clearing members’ cash contributions are included in default funds and margin deposits in the Condensed Consolidated Balance Sheets as both a current asset and a current liability. Non-cash contributions include highly rated government debt securities that must meet specific criteria approved by Nasdaq Clearing. Non-cash contributions are pledged assets that are not recorded in the Condensed Consolidated Balance Sheets as Nasdaq Clearing does not take legal ownership of these assets and the risks and rewards remain with the clearing members. These balances may fluctuate over time due to changes in the amount of deposits required and whether members choose to provide cash or non-cash contributions. Assets pledged are held at a nominee account in Nasdaq Clearing’s name for the benefit of the clearing members and are immediately accessible by Nasdaq Clearing in the event of a default. In addition to clearing members’ required contributions to the liability waterfall, Nasdaq Clearing is also required to contribute capital to the liability waterfall and overall regulatory capital as specified under its clearinghouse rules. As of June 30, 2018, Nasdaq Clearing committed capital totaling $108 million to the liability waterfall and overall regulatory capital, in the form of government debt securities, which are recorded as financial investments, at fair value in the Condensed Consolidated Balance Sheets. The combined regulatory capital of the clearing members and Nasdaq Clearing will serve to secure the obligations of a clearing member and may be used to cover losses sustained by a clearing member in the event of a default.

Margin Deposits

Nasdaq Clearing requires all clearing members to provide collateral, which may consist of cash and non-cash contributions, to guarantee performance on the clearing members’ open positions, or initial margin. In addition, clearing members must also provide collateral to cover the daily margin call if needed. See “Default Fund Contributions” above for further discussion of cash and non-cash contributions.

Similar to default fund contributions, Nasdaq Clearing maintains and manages all cash deposits related to margin collateral. All risks and rewards of collateral ownership, including interest, belong to Nasdaq Clearing. These cash deposits are recorded in default funds and margin deposits in the Condensed Consolidated Balance Sheets as both a current asset and current liability. Pledged margin collateral is not recorded in our Condensed Consolidated Balance Sheets as all risks and rewards of collateral ownership, including interest, belong to the counterparty. Assets pledged are held at a nominee account in Nasdaq Clearing’s name for the benefit of the clearing members and are immediately accessible by Nasdaq Clearing in the event of a default.

Nasdaq Clearing marks to market all outstanding contracts and requires payment from clearing members whose positions have lost value. The mark-to-market process helps identify any clearing members that may not be able to satisfy their financial obligations in a timely manner allowing Nasdaq Clearing the ability to mitigate the risk of a clearing member defaulting due to exceptionally large losses. In the event of a default, Nasdaq Clearing can access the defaulting member’s margin deposits to cover the defaulting member’s losses.

Regulatory Capital and Risk Management Calculations

Nasdaq Clearing manages risk through a comprehensive counterparty risk management framework, which is comprised of policies, procedures, standards and financial resources. The level of regulatory capital is determined in accordance with Nasdaq Clearing’s regulatory capital policy, as approved by the SFSA. Regulatory capital calculations are continuously updated through a proprietary capital-at-risk calculation model that establishes the appropriate level of capital.

As mentioned above, Nasdaq Clearing is the legal counterparty for each contract traded and thereby guarantees the fulfillment of each contract. Nasdaq Clearing accounts for this guarantee as a performance guarantee. We determine the fair value of the performance guarantee by considering daily settlement of contracts and other margining and default fund requirements, the risk management program, historical evidence of default payments, and the estimated probability of potential default payouts. The calculation is determined using proprietary risk management software that simulates gains and losses based on historical market prices, extreme but plausible market scenarios, volatility and other factors present at that point in time for those particular unsettled contracts. Based on this analysis, the estimated liability was nominal and no liability was recorded as of June 30, 2018. 

The market value of derivative contracts outstanding prior to netting was as follows:

	June 30, 2018
	(in millions)
Commodity and seafood options, futures and forwards(1)(2)(3)	$	1,447
Fixed-income options and futures(1)(2)	763
Stock options and futures(1)(2)	260
Index options and futures(1)(2)	80
Total	$	2,550

____________

⁽¹⁾  We determined the fair value of our option contracts using standard valuation models that were based on market-based observable inputs including implied volatility, interest rates and the spot price of the underlying instrument.

⁽²⁾  We determined the fair value of our futures contracts based upon quoted market prices and average quoted market yields.

⁽³⁾  We determined the fair value of our forward contracts using standard valuation models that were based on market-based observable inputs including LIBOR rates and the spot price of the underlying instrument.

The total number of derivative contracts cleared through Nasdaq Clearing for the six months ended June 30, 2018 and 2017 was as follows:

	June 30, 2018	June 30, 2017
Commodity and seafood options, futures and forwards(1)	1,162,716	1,397,771
Fixed-income options and futures	11,286,397	10,160,127
Stock options and futures	11,940,062	13,526,164
Index options and futures	24,641,397	21,616,323
Total	49,030,572	46,700,385

____________

(1) The total volume in cleared power related to commodity contracts was 577 Terawatt hours (TWh) for the six months ended June 30, 2018 and 647 TWh for the six months ended June 30, 2017.

The outstanding contract value of resale and repurchase agreements was $3.4 billion as of June 30, 2018 and $4.4 billion as of June 30, 2017. The total number of contracts cleared was 4,498,651 for the six months ended June 30, 2018 and was 3,953,901 for the six months ended June 30, 2017.

Power of Assessment 

To further strengthen the contingent financial resources of the clearinghouse, Nasdaq Clearing has power of assessment that provides the ability to collect additional funds from its clearing members to cover a defaulting member’s remaining obligations up to the limits established under the terms of the clearinghouse rules. The power of assessment corresponds to 100.0% of the clearing member’s aggregate contribution to the financial, commodities and seafood markets’ default funds.

Liability Waterfall

The liability waterfall is the priority order in which the capital resources would be utilized in the event of a default where the defaulting clearing member’s collateral would not be sufficient to cover the cost to settle its portfolio. If a default occurs and the defaulting clearing member’s collateral, including cash deposits and pledged assets, is depleted, then capital is utilized in the following amount and order:

• junior capital contributed by Nasdaq Clearing, which totaled $16 million as of June 30, 2018;

• a loss sharing pool related only to the financial market that is contributed to by clearing members and only applies if the defaulting member’s portfolio includes interest rate swap products;

• specific market default fund where the loss occurred (i.e., the financial, commodities, or seafood market), which includes capital contributions of the clearing members on a pro-rata basis;

• senior capital contributed to each specific market by Nasdaq Clearing, calculated in accordance with clearinghouse rules, which totaled $23 million as of June 30, 2018; and

• mutualized default fund, which includes capital contributions of the clearing members on a pro-rata basis.

In addition to the capital held to withstand counterparty defaults described above, Nasdaq Clearing also has committed capital of $69 million to ensure that it can handle an orderly wind-down of its operation, and that it is adequately protected against investment, operational, legal, and business risks. If additional funds are needed after utilization of the mutualized default fund, then Nasdaq Clearing will utilize its power of assessment and additional capital contributions will be required by non-defaulting members up to the limits established under the terms of the clearinghouse rules.

Commitments, Contingencies and Guarantees

Guarantees Issued and Credit Facilities Available

In addition to the default fund contributions and margin collateral pledged by clearing members discussed in Note 15, “Clearing Operations,” we have obtained financial guarantees and credit facilities which are guaranteed by us through counter indemnities, to provide further liquidity related to our clearing businesses. Financial guarantees issued to us totaled $12 million as of June 30, 2018 and $14 million as of December 31, 2017. As discussed in “Other Credit Facilities,” of Note 9, “Debt Obligations,” clearing-related credit facilities, which are available in multiple currencies, totaled $218 million as of June 30, 2018 and $187 million as of December 31, 2017, in available liquidity, none of which was utilized.

Execution Access is an introducing broker which operates the trading platform for our Fixed Income business to trade in U.S. Treasury securities. Execution Access has a clearing arrangement with Cantor Fitzgerald. As of June 30, 2018, we have contributed $19 million of clearing deposits to Cantor Fitzgerald in connection with this clearing arrangement. This clearing agreement ended on July 31, 2018, and has been replaced by a clearing agreement with the Industrial and Commercial Bank of China Financial Services LLC, or ICBC, where all trades have cleared since June 25, 2018. As a result, we also have contributed $15 million of clearing deposits to ICBC. These deposits are recorded in other current assets in our Condensed Consolidated Balance Sheets. In July 2018, the majority of the clearing deposit of $19 million which was contributed to Cantor Fitzgerald has been reimbursed. Some of the trading activity in Execution Access is cleared by ICBC through the Fixed Income Clearing Corporation, with ICBC acting as agent. Execution Access assumes the counterparty risk of clients that do not clear through the Fixed Income Clearing Corporation. Counterparty risk of clients exists for Execution Access between the trade date and the settlement date of the individual transactions, which is at least one business day (or more, if specified by the U.S. Treasury issuance calendar). Counterparties that do not clear through the Fixed Income Clearing Corporation are subject to a credit due diligence process and may be required to post collateral, provide principal letters, or provide other forms of credit enhancement to Execution Access for the purpose of mitigating counterparty risk. Daily position trading limits are also enforced for such counterparties.

We believe that the potential for us to be required to make payments under these arrangements is mitigated through the pledged collateral and our risk management policies. Accordingly, no contingent liability is recorded in the Condensed Consolidated Balance Sheets for these arrangements. However, no guarantee can be provided that these arrangements will at all times be sufficient.

We lease some of our office space under non-cancelable operating leases with third parties and sublease office space to third parties. Some of our lease agreements contain renewal options and escalation clauses based on increases in property taxes and building operating costs.

Other Guarantees

We have provided other guarantees of $2 million as of June 30, 2018 and $3 million as of December 31, 2017. These guarantees are primarily related to obligations for our rental and leasing contracts as well as performance guarantees on certain market technology contracts related to the delivery of software technology and support services. We have received financial guarantees from various financial institutions to support the above guarantees.

Through our clearing operations in the financial markets, Nasdaq Clearing is the legal counterparty for, and guarantees the performance of, its clearing members. See Note 15, “Clearing Operations,” for further discussion of Nasdaq Clearing performance guarantees.

We have provided a guarantee related to lease obligations for The Nasdaq Entrepreneurial Center, Inc. which is a not-for-profit organization designed to convene, connect and engage aspiring and current entrepreneurs. This entity is not included in the consolidated financial statements of Nasdaq.

We believe that the potential for us to be required to make payments under these arrangements is unlikely. Accordingly, no contingent liability is recorded in the Condensed Consolidated Balance Sheets for the above guarantees.

Non-Cash Contingent Consideration 

As part of the purchase price consideration of a prior acquisition, we have agreed to future annual issuances of 992,247 shares of Nasdaq common stock which approximated certain tax benefits associated with the transaction. Such contingent future issuances of Nasdaq common stock will be paid ratably through 2027 if Nasdaq’s total gross revenues equal or exceed $25 million in each such year. The contingent future issuances of Nasdaq common stock are subject to anti-dilution protections and acceleration upon certain events.

Escrow Agreements

In connection with prior acquisitions, we entered into escrow agreements to secure the payment of post-closing adjustments and to ensure other closing conditions. As of June 30, 2018, these escrow agreements provide for future payment of $13 million, of which $9 million is included in other current liabilities and $4 million is included in other non-current liabilities in the Condensed Consolidated Balance Sheets.

Routing Brokerage Activities

One of our broker-dealer subsidiaries, Nasdaq Execution Services, provides a guarantee to securities clearinghouses and exchanges under its standard membership agreements, which require members to guarantee the performance of other members. If a member becomes unable to satisfy its obligations to a clearinghouse or exchange, other members would be required to meet its shortfalls. To mitigate these performance risks, the exchanges and clearinghouses often require members to post collateral, as well as meet certain minimum financial standards. Nasdaq Execution Services’ maximum potential liability under these arrangements cannot be quantified. However, we believe that the potential for Nasdaq Execution Services to be required to make payments under these arrangements is unlikely. Accordingly, no contingent liability is recorded in the Condensed Consolidated Balance Sheets for these arrangements.

Other Commitments

We have a 40.0% ownership in OCC. Under the OCC's capital plan, the OCC shareholders have committed to contribute up to $200 million in equity capital if certain capital thresholds are breached, including up to $80 million to be contributed by Nasdaq. See “Equity Method Investments,” of Note 7, “Investments,” for further discussion of our equity method investment in OCC.

Legal and Regulatory Matters 

As previously disclosed, we are named as one of many defendants in City of Providence v. BATS Global Markets, Inc., et al., 14 Civ. 2811 (S.D.N.Y.), which was filed on April 18, 2014 in the United States District Court for the Southern District of New York. The district court appointed lead counsel, who filed an amended complaint on September 2, 2014. The amended complaint names as defendants seven national exchanges, as well as Barclays PLC, which operated a private alternative trading system. On behalf of a putative class of securities traders, the plaintiffs allege that the defendants engaged in a scheme to manipulate the markets through high-frequency trading; the amended complaint asserts claims against us under Section 10(b) of the Exchange Act and Rule 10b-5, as well as under Section 6(b) of the Exchange Act. The plaintiffs seek injunctive and monetary relief of an unspecified amount. We filed a motion to dismiss the amended complaint on November 3, 2014. In response, the plaintiffs filed a second amended complaint on November 24, 2014, which names the same defendants and alleges essentially the same violations. We then filed a motion to dismiss the second amended complaint on January 23, 2015. On August 26, 2015, the district court entered an order dismissing the second amended complaint in its entirety with prejudice, concluding that most of the plaintiffs’ theories were foreclosed by absolute immunity and in any event that the plaintiffs failed to state any claim. The plaintiffs appealed the judgment of dismissal to the United States Court of Appeals for the Second Circuit. On December 19, 2017, the Second Circuit issued an opinion vacating the district court’s judgment of dismissal and remanding to the district court for further proceedings. The exchanges filed a petition before the Second Circuit seeking panel or en banc rehearing on January 31, 2018, which the Second Circuit denied on March 13, 2018. On May 18, 2018, the exchanges filed a motion to dismiss the amended complaint, raising issues not addressed in the proceedings to date. Given the preliminary nature of the proceedings, we are unable to estimate what, if any, liability may result from this litigation. However, we believe that the claims are without merit and will continue to litigate vigorously.

Except as disclosed above and in prior reports filed under the Exchange Act, we are not currently a party to any litigation or proceeding that we believe could have a material adverse effect on our business, consolidated financial condition, or operating results. However, from time to time, we have been threatened with, or named as a defendant in, lawsuits or involved in regulatory proceedings.

In the normal course of business, Nasdaq discusses matters with its regulators raised during regulatory examinations or otherwise subject to their inquiry and oversight. These matters could result in censures, fines, penalties or other sanctions. Management believes the outcome of any resulting actions will not have a material impact on its consolidated financial position or results of operations. However, we are unable to predict the outcome or the timing of the ultimate resolution of these matters, or the potential fines, penalties or injunctive or other equitable relief, if any, that may result from these matters.

Tax Audits

We are engaged in ongoing discussions and audits with taxing authorities on various tax matters, the resolutions of which are uncertain. Currently, there are matters that may lead to assessments, some of which may not be resolved for several years. Based on currently available information, we believe we have adequately provided for any assessments that could result from those proceedings where it is more likely than not that we will be assessed. We review our positions on these matters as they progress.

Income Tax Disclosure [Abstract]

Income Taxes

Income Taxes

We use the asset and liability method to determine income taxes on all transactions recorded in the consolidated financial statements. Deferred tax assets (net of valuation allowances) and deferred tax liabilities are presented net by jurisdiction as either a non-current asset or liability in our Condensed Consolidated Balance Sheets, as appropriate. Deferred tax assets and liabilities are determined based on differences between the financial statement carrying amounts and the tax basis of existing assets and liabilities (i.e., temporary differences) and are measured at the enacted rates that will be in effect when these differences are realized. If necessary, a valuation allowance is established to reduce deferred tax assets to the amount that is more likely than not to be realized. As of June 30, 2018 and December 31, 2017, net deferred tax assets are included in other non-current assets in the Condensed Consolidated Balance Sheets.

In order to recognize and measure our unrecognized tax benefits, management determines whether a tax position is more likely than not to be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. Once it is determined that a position meets the recognition thresholds, the position is measured to determine the amount of benefit to be recognized in the consolidated financial statements. Interest and/or penalties related to income tax matters are recognized in income tax expense.

The following table shows our income tax provision and effective tax rate:

	Three Months Ended June 30,						Percentage Change
	2018			2017
	($ in millions)
Income tax provision	$	126		$	65		93.8	%
Effective tax rate	43.8		%	30.8		%
	Six Months Ended June 30,						Percentage Change
	2018			2017
	($ in millions)
Income tax provision	$	188		$	113		66.4	%
Effective tax rate	35.7		%	26.5		%

The higher effective tax rate in the second quarter and first six months of 2018 when compared with the same periods in 2017 is primarily due to the reversal of certain Swedish tax benefits recorded in prior periods and the tax expense associated with the sale of the Public Relations Solutions and Digital Media Services businesses. Also, we recorded a lower recognition of excess tax benefits associated with the vesting of employee share-based compensation arrangements in the first six months of 2018 compared to the same period in 2017. These increases are partially offset by a decrease in tax expense due to the reduction of the U.S. corporate tax rate from 35% to 21%, effective January 1, 2018.

The effective tax rate may also vary from period to period depending on, among other factors, the geographic and business mix of earnings and losses. These same and other factors, including history of pre-tax earnings and losses, are taken into account in assessing the ability to realize deferred tax assets.

Nasdaq and its eligible subsidiaries file a consolidated U.S. federal income tax return and applicable state and local income tax returns and non-U.S. income tax returns. Federal income tax returns for the years 2012 through 2015 are currently under examination by the Internal Revenue Services and we are subject to examination by the Internal Revenue Service for 2016. Several state tax returns are currently under examination by the respective tax authorities for the years 2005 through 2016. Non-U.S. tax returns are subject to examination by the respective tax authorities for the years 2009 through 2016. Although the results of such examinations may have an impact on our unrecognized tax benefits, we do not anticipate that such impact will be material to our consolidated financial position or results of operations. In addition, we anticipate that the amount of unrecognized tax benefits as of June 30, 2018 will decrease in the next twelve months as we expect to settle certain tax audits.

The Swedish Tax Agency has disallowed certain interest expense deductions for the years 2013 - 2016. We appealed to the Lower Administrative Court for the years 2013 - 2015. In the first quarter of 2018, the Lower Administrative Court denied our appeal. We have appealed to the Administrative Court of Appeal. Through March 31, 2018, we had recorded tax benefits of $57 million associated with this matter. We continue to pay all assessments from the Swedish Tax Agency while this matter is pending and have paid $40 million through June 30, 2018. In the second quarter of 2018, the Administrative Court of Appeal decided similar cases against other taxpayers. Although we continue to assert the validity of these interest expense deductions, the decisions of the court lead us to conclude that we can no longer assert that we are more than likely to be successful in our appeal. As such, in the second quarter of 2018, we recorded tax expense of $41 million, or $0.24 per diluted share, which is net of any related U.S. tax benefits and reflects the impact of foreign currency translation. We expect to record future quarterly net tax expense of $1 million related to this matter.

The Tax Cuts and Jobs Act was enacted on December 22, 2017 and was effective January 1, 2018. The new legislation contains several key provisions, including a reduction of the U.S. corporate income tax rate from 35% to 21%. We were required to remeasure all of our U.S. deferred tax assets and liabilities as of December 22, 2017 and record the impact of such remeasurement in our 2017 financial statements. For the year ended December 31, 2017, we recorded a decrease to tax expense of $89 million, substantially all of which reflects the estimated impact associated with the remeasurement of our net U.S. deferred tax liability at the lower U.S. federal corporate income tax rate. The Tax Cuts and Jobs Act also imposes a transition tax on unremitted aggregate accumulated earnings of non-U.S. subsidiaries, which did not impact us.

SEC Staff Accounting Bulletin No. 118, “Income Tax Accounting Implications of the Tax Cuts and Jobs Act,” has provided guidance which allows us to record provisional amounts during a measurement period not to extend beyond one year of the enactment date. As of December 31, 2017, we recorded a provisional estimate of the effects of the new legislation. In the first quarter of 2018, we recorded an increase to tax expense of $5 million, which reflects the reduced federal tax benefit associated with state unrecognized tax benefits. We will continue to analyze the Tax Cuts and Jobs Act and related accounting guidance and interpretations in order to finalize any impacts within the measurement period.

On January 1, 2018, we adopted Topic 220. See “Recent Accounting Pronouncements,” of Note 2, “Basis of Presentation and Principles of Consolidation,” for further discussion of this standard. As a result of the adoption of this standard, in the first quarter of 2018, we recorded a reclassification of $142 million for stranded tax effects related to the Tax Cuts and Jobs Act from accumulated other comprehensive loss to retained earnings within stockholders’ equity in the Condensed Consolidated Balance Sheets. Of the $142 million of stranded tax effects, $135 million relates to the effect on net foreign currency translation gains and losses and $7 million relates to the effect on employee benefit plan adjustment gains and losses.

Segment Reporting [Abstract]

Business Segments

Business Segments

We manage, operate and provide our products and services in four business segments: Market Services, Corporate Services, Information Services and Market Technology. See Note 1, “Organization and Nature of Operations,” for further discussion of our reportable segments.

Our management allocates resources, assesses performance and manages these businesses as four separate segments. We evaluate the performance of our segments based on several factors, of which the primary financial measure is operating income. Results of individual businesses are presented based on our management accounting practices and structure.

* * * * * *

The following table presents certain information regarding our operating segments for the three and six months ended June 30, 2018 and 2017:

	Market Services			Corporate Services		Information Services		Market Technology		Corporate Items			Consolidated

Certain amounts are allocated to corporate items in our management reports based on the decision that those activities should not be used to evaluate the segment’s ongoing operating performance. We have included in corporate items the revenues and expenses of the Public Relations Solutions and Digital Media Services businesses which were part of the Corporate Solutions business within our Corporate Services segment as these businesses were sold in April 2018. See “2018 Divestiture,” of Note 4, “Divestiture and Acquisitions,” for further discussion. In addition, the following items are allocated to corporate items for segment reporting purposes:

Amortization expense of acquired intangible assets: We amortize intangible assets acquired in connection with various acquisitions. Intangible asset amortization expense can vary from period to period due to episodic acquisitions completed, rather than from our ongoing business operations. As such, if intangible asset amortization is included in performance measures, it is more difficult to assess the day-to-day operating performance of the segments, and the relative operating performance of the segments between periods. Management does not consider intangible asset amortization expense for the purpose of evaluating the performance of our segments or their managers or when making decisions to allocate resources. Therefore, we believe performance measures excluding intangible asset amortization expense provide management with a more useful representation of our segments' ongoing activity in each period.

Merger and strategic initiatives expense:We have pursued various strategic initiatives and completed a divestiture and a number of acquisitions in recent years which have resulted in expenses which would not have otherwise been incurred. These expenses generally include integration costs, as well as legal, due diligence and other third party transaction costs. The frequency and the amount of such expenses vary significantly based on the size, timing and complexity of the transaction. Accordingly, we do not allocate these costs for purposes of disclosing segment results because they do not contribute to a meaningful evaluation of a particular segment’s ongoing operating performance.

Other significant items: We have excluded certain other charges or gains that are the result of other non-comparable events to measure operating performance. For the three and six months ended June 30, 2018, other significant items included a sales and use tax charge which related to prior periods. For the six months ended June 30, 2018, other significant items also included a sublease loss reserve charge recorded on space we currently occupy due to excess capacity. For the three and six months ended June 30, 2017, other significant items included loss on extinguishment of debt. We believe the exclusion of such amounts allows management and investors to better understand the financial results of Nasdaq.

Basis of Presentation and Principles of Consolidation (Policies)

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation

The condensed consolidated financial statements are prepared in accordance with U.S. GAAP and include the accounts of Nasdaq, its wholly-owned subsidiaries and other entities in which Nasdaq has a controlling financial interest. When we do not have a controlling interest in an entity but exercise significant influence over the entity’s operating and financial policies, such investment is accounted for under the equity method of accounting. We recognize our share of earnings or losses of an equity method investee based on our ownership percentage. See “Equity Method Investments,” of Note 7, “Investments,” for further discussion of our equity method investments.

Consolidation

The accompanying condensed consolidated financial statements reflect all adjustments which are, in the opinion of management, necessary for a fair statement of the results for the interim periods presented. These adjustments are of a normal recurring nature. All significant intercompany accounts and transactions have been eliminated in consolidation.

As permitted under U.S. GAAP, certain footnotes or other financial information can be condensed or omitted in the interim condensed consolidated financial statements. The information included in this Quarterly Report on Form 10-Q should be read in conjunction with the consolidated financial statements and accompanying notes included in Nasdaq’s Annual Report on Form 10-K for the fiscal year ended December 31, 2017.

Certain prior year amounts have been reclassified to conform to the current year presentation primarily due to the adoption of ASU 2014-09, “Revenue from Contracts with Customers (Topic 606),” on January 1, 2018. See Note 3, “Significant Accounting Policies Update,” for further discussion.

Use of Estimates

The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts and the disclosure of contingent amounts in the condensed consolidated financial statements and accompanying notes. Actual results could differ from those estimates.

Recently Accounting Pronouncements

Recent Accounting Pronouncements

Accounting Standard	Description	Effective Date	Effect on the Financial Statements or Other Significant Matters
Income Statement - Reporting Comprehensive Income In February 2018, the FASB issued ASU 2018-02, “Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (Topic 220).”	This ASU provides an election to reclassify tax effects that are stranded in accumulated other comprehensive income as a result of tax reform to retained earnings. An election is also available to reclassify other stranded tax effects that relate to the Tax Cuts and Jobs Act but do not directly relate to the change in the federal rate. Tax effects that are stranded in accumulated other comprehensive income for other reasons (e.g., prior changes in tax law, a change in valuation allowance) may not be reclassified. Previously, the effects of changes in tax rates and laws on deferred tax balances were required to be recorded as a component of tax expense related to continuing operations for the period in which the law was enacted, even if the assets and liabilities related to items of accumulated other comprehensive income. In other words, backward tracing of the income tax effects of items originally recognized through accumulated other comprehensive income was prohibited.	January 1, 2019, with early adoption permitted. We early adopted this standard on January 1, 2018.	As a result of the adoption of this standard, in the first quarter of 2018, we recorded a reclassification of $142 million for stranded tax effects related to the Tax Cuts and Jobs Act from accumulated other comprehensive loss to retained earnings within stockholders’ equity in the Condensed Consolidated Balance Sheets. See Note 17, “Income Taxes,” for further discussion.
Goodwill In January 2017, the FASB issued ASU 2017-04, “Simplifying the Test for Goodwill Impairment.”	This ASU simplifies how an entity is required to test goodwill for impairment and removes the second step of the goodwill impairment test, which required a hypothetical purchase price allocation if the fair value of a reporting unit is less than its carrying amount. Goodwill impairment will now be measured using the difference between the carrying amount and the fair value of the reporting unit and the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. The amendments in this ASU should be applied on a prospective basis.	January 1, 2020, with early adoption permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017.	We do not anticipate a material impact on our consolidated financial statements at the time of adoption of this new standard as the carrying amounts of our reporting units have been less than their corresponding fair values in recent years. Therefore, the second step of the goodwill impairment test was not required. However, changes in future projections, market conditions and other factors may cause a change in the excess of fair value of our reporting units over their corresponding carrying amounts. We do not anticipate early adoption of this standard.
Financial Instruments - Credit Losses In June 2016, the FASB issued ASU 2016-13, “Measurement of Credit Losses on Financial Instruments.”	This ASU changes the impairment model for certain financial instruments. The new model is a forward looking expected loss model and will apply to financial assets subject to credit losses and measured at amortized cost and certain off-balance sheet credit exposures. This includes loans, held-to-maturity debt securities, loan commitments, financial guarantees and net investments in leases, as well as trade receivables. For available-for-sale debt securities with unrealized losses, credit losses will be measured in a manner similar to today, except that the losses will be recognized as allowances rather than reductions in the amortized cost of the securities.	January 1, 2020, with early adoption permitted as of January 1, 2019.	We are currently assessing the impact that this standard will have on our consolidated financial statements. We do not anticipate early adoption of this standard.

Accounting Standard	Description	Effective Date	Effect on the Financial Statements or Other Significant Matters
Leases In February 2016, the FASB issued ASU 2016-02, “Leases.”	Under this ASU, at the commencement date, lessees will be required to recognize a lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis; and a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. This guidance is not applicable for leases with a term of 12 months or less. Recognition, measurement and presentation of expenses will depend on classification as a finance or operating lease. The guidance also requires certain quantitative and qualitative disclosures about leasing arrangements. Lessor accounting is largely unchanged. In transition, lessees and lessors are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach.	January 1, 2019, with early adoption permitted.	See discussion below.

Leases

When adopted, ASU 2016-02 will result in an increase in the assets and liabilities reflected on our consolidated balance sheets. In addition, we will be required to disclose key information about our leases. We are in the process of determining the scope of arrangements that will be subject to this standard, as well as assessing the impact to our business processes, systems and internal controls to support adoption of this new standard. Nasdaq’s current operating lease portfolio is primarily comprised of real estate and data center leases.

We plan to adopt this new standard on January 1, 2019. The guidance is to be applied using a modified retrospective transaction approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. However, in March 2018, the FASB approved an optional transition alternative, which allows for application of the guidance at the effective date, without adjusting the comparative periods presented.

While we continue to assess the effect of adoption of this new standard and the available practical expedients, we expect that most of our operating lease commitments will be subject to the new guidance and will be recognized as right-of-use assets and lease liabilities upon adoption in our consolidated balance sheets. We do not expect the adoption of this new standard to have a material impact on our consolidated statements of income and it will not impact our cash flows.

Revenue From Contracts With Customers

On January 1, 2018, we adopted Topic 606 using the full retrospective method. The adoption of Topic 606 impacted the revenue and expense recognition for our Market Technology business and revenue recognition for our Listing Services business. However, the adoption of Topic 606 did not have a material impact on our consolidated financial statements at the time of adoption or in any prior reporting periods. There was no impact to revenue and expense recognition for our other businesses. Additional disclosures required by Topic 606 are provided below.

Contract Balances

Substantially all of our revenues are considered to be revenues from contracts with customers. The related accounts receivable balances are recorded in our Condensed Consolidated Balance Sheets as receivables which is net of allowance for doubtful accounts of $13 million as of June 30, 2018 and $9 million as of December 31, 2017. The changes in the balance between periods were immaterial. We do not have obligations for warranties, returns or refunds to customers.

For the majority of our contracts with customers, except for our market technology and listings services contracts, our performance obligations are short-term in nature and there is no significant variable consideration.

We do not have significant revenues recognized from performance obligations that were satisfied in prior periods. We have elected not to provide disclosures about transaction price allocated to unsatisfied performance obligations if contract durations are less than one year. For contract durations that are one-year or greater, we do not have a material portion of transaction price allocated to unsatisfied performance obligations that are not included in deferred revenue other than for our market technology contracts which are discussed below under “Market Technology.” Deferred revenue primarily represents our contract liabilities related to our fees for annual and initial listings, market technology, corporate solutions and information services contracts. Deferred revenue is the only significant contract asset or liability impacted by our adoption of Topic 606. See Note 8, “Deferred Revenue,” for our discussion on deferred revenue balances, activity, and expected timing of recognition. See “Revenue Recognition” below for further descriptions of our revenue contracts.

Sales commissions earned by our sales force are considered incremental and recoverable costs of obtaining a contract with a customer. These costs are deferred and amortized on a straight-line basis over the period of benefit that we have determined to be the contract term or estimated service periods. Sales commissions for renewal contracts are deferred and amortized on a straight-line basis over the related contractual renewal period. Amortization expense is included in compensation and benefits expense in the Condensed Consolidated Statements of Income. The balance of deferred costs and related amortization expense are not material to our consolidated financial statements. We elected the practical expedient of recognizing sales commissions as an expense when incurred if contract durations are one year or less. We also have elected the practical expedient of excluding sales taxes from transaction prices.

Certain judgments and estimates were used in the identification and timing of satisfaction of performance obligations and the related allocation of transaction price and are discussed below. We believe that these represent a faithful depiction of the transfer of services to our customers.

Revenue Recognition

Our primary revenue contract classifications are described below. Though we discuss additional revenue details in our “Management's Discussion and Analysis of Financial Condition and Results of Operations,” the categories below best represent those that depict similar economic characteristics of the nature, amount, timing and uncertainty of our revenues and cash flows.

Market Services

Transaction-Based Trading and Clearing

Transaction-based trading and clearing includes equity derivative trading and clearing revenues, cash equity trading revenues and FICC revenues. Nasdaq charges transaction fees for trades executed on our exchanges, as well as on orders that are routed to and executed on other market venues. Nasdaq charges clearing fees for contracts cleared with Nasdaq Clearing.

In the U.S., transaction fees are based on trading volumes for trades executed on our U.S. exchanges and in Europe, transaction fees are based on the volume and value of traded and cleared contracts. In Canada, transaction fees are based on trading volumes for trades executed on our Canadian exchange.

Nasdaq satisfies its performance obligation for trading services upon the execution of a customer trade and clearing services when a contract is cleared, as trading and clearing transactions are substantially complete when they are executed and we have no further obligation to the customer at that time. Transaction-based trading and clearing fees can be variable and are based on trade volume tiered discounts. Transaction revenues, as well as any tiered volume discounts, are calculated and billed monthly in accordance with our published fee schedules. In the U.S., we also pay liquidity payments to customers based on our published fee schedules. We use these payments to improve the liquidity on our markets and therefore recognize those payments as a cost of revenue.

The majority of our FICC trading and clearing customers are charged transaction fees, as discussed above, which are based on the volume and value of traded and cleared contracts. We also enter into annual fixed contracts with customers trading U.S. Treasury securities. The customers are charged an annual fixed fee which is billed per the agreement, on a monthly or quarterly basis. Revenues earned on fixed contracts are recognized over time on a ratable basis over the contract period beginning on the date that our service is made available to the customer since the customer receives and consumes the benefit as Nasdaq provides the service.

For U.S. equity derivative trading, we credit a portion of the per share execution charge to the market participant that provides the liquidity. For U.S. cash equity trading, for Nasdaq and Nasdaq PSX, we credit a portion of the per share execution charge to the market participant that provides the liquidity and for Nasdaq BX, we credit a portion of the per share execution charge to the market participant that takes the liquidity. We record these credits as transaction rebates that are included in transaction-based expense in the Condensed Consolidated Statements of Income. These transaction rebates are paid on a monthly basis and the amounts due are included in accounts payable and accrued expenses in the Condensed Consolidated Balance Sheets.

In the U.S., we pay Section 31 fees to the SEC for supervision and regulation of securities markets. We pass these costs along to our customers through our equity derivative trading and clearing fees and our cash equity trading fees. We collect the fees as a pass-through charge from organizations executing eligible trades on our options exchanges and our cash equity platforms and we recognize these amounts in transaction-based expenses when incurred. Section 31 fees received are included in cash and cash equivalents in the Condensed Consolidated Balance Sheets at the time of receipt and, as required by law, the amount due to the SEC is remitted semiannually and recorded as Section 31fees payable to the SEC in the Condensed Consolidated Balance Sheets until paid. Since the amount recorded as revenues is equal to the amount recorded as transaction-based expenses, there is no impact on our revenues less transaction-based expenses. As we hold the cash received until payment to the SEC, we earn interest income on the related cash balances.

Under our Limitation of Liability Rule and procedures, we may, subject to certain caps, provide compensation for losses directly resulting from the systems’ actual failure to correctly process an order, quote, message or other data into our platform. We do not record a liability for any potential claims that may be submitted under the Limitation of Liability Rule unless they meet the provisions required in accordance with U.S. GAAP. As such, losses arising as a result of the rule are accrued and charged to expense only if the loss is probable and estimable.

Trade Management Services

We provide market participants with a wide variety of alternatives for connecting to and accessing our markets for a fee. We also offer market participants co-location services, whereby firms may lease cabinet space and power to house their own equipment and servers within our data centers. These participants are charged monthly fees for cabinet space, connectivity and support in accordance with our published fee schedules and recognized on a monthly basis when the performance obligation is met. We also earn revenues from annual and monthly exchange membership and registration fees. Revenues for providing access to our markets, co-location services and monthly exchange membership and registration fees are recognized on a monthly basis as the service is provided. Revenues from annual fees for exchange membership and registration fees are recognized ratably over the following 12-month period since the customer receives and consumes the benefit as Nasdaq provides the service. We also offer broker services to financial participants in the Nordic market primarily providing flexible back-office systems, which allow customers to entirely or partly outsource their company’s back-office functions. Revenues from broker services are based on a fixed basic fee for administration or licensing, maintenance and operations, and an incremental fee depending on the number of transactions completed. Broker services revenues are generally billed and recognized monthly.

Corporate Solutions

As of June 30, 2018, corporate solutions revenues primarily include subscription and transaction-based income from our investor relations, board & leadership, and governance, risk and compliance products and services. In April 2018, we completed the sale of our Public Relations Solutions and Digital Media Services businesses. See “2018 Divestiture,” of Note 4, “Divestiture and Acquisitions,” for further discussion. Subscription-based revenues earned are recognized over time on a ratable basis over the contract period beginning on the date that our service is made available to the customer since the customer receives and consumes the benefit as Nasdaq provides the service. Generally, fees are billed quarterly in advance and the contract provides for automatic renewal. As part of the subscription agreements, customers can also be charged usage fees based upon actual usage of the services provided. Revenues from usage fees are recognized at a point in time upon completion of the service.

Listing Services

Listing services revenues primarily include initial listing fees and annual renewal fees. Under Topic 606, the initial listing fee is allocated to multiple performance obligations including initial and subsequent listing services and corporate solutions services (when a company qualifies to receive these services under the applicable Nasdaq rule), as well as a customer's material right to renew the option to list on our exchanges. In performing this allocation, the standalone selling price of the performance obligations is based on the initial and annual listing fees and the standalone selling price of the corporate solutions services is based on its market value. All listing fees are billed upfront and the identified performance obligations are satisfied over time since the customer receives and consumes the benefit as Nasdaq provides the listing service. Upon adoption of Topic 606, the amount of revenue related to the corporate solutions services performance obligation is recognized ratably over a two-year period, which is based on contract terms, with the remaining revenue recognized ratably over time as customers continue to list on our exchanges, which is estimated to be over a period of six years based on our historical listing experience and projected future listing duration.

In the U.S., annual renewal fees are charged based on the number of outstanding shares of companies listed in the U.S. at the end of the prior year and are recognized ratably over the following 12-month period since the customer receives and consumes the benefit as Nasdaq provides the service. European annual renewal fees, which are received from companies listed on our Nasdaq Nordic and Nasdaq Baltic exchanges and Nasdaq First North, are directly related to the listed companies’ market capitalization on a trailing 12-month basis and are recognized ratably over the following 12-month period since the customer receives and consumes the benefit as Nasdaq provides the service.

Market Data Products

Market data products revenues are earned from U.S. and European proprietary market data products. In the U.S., we also earn revenues from U.S. shared tape plans.

We earn revenues primarily based on the number of data subscribers and distributors of our data. Market data products revenues are subscription-based and are recognized on a monthly basis net of amounts due under revenue sharing arrangements with market participants.

For U.S. tape plans, revenues are collected monthly based on published fee schedules and distributed quarterly to the U.S. exchanges based on a formula required by Regulation NMS that takes into account both trading and quoting activity. Revenues are presented on a net basis as we are acting as an agent in this arrangement.

Market Data Products Revenue Sharing

The most significant component of market data products revenues recorded on a net basis is the UTP Plan revenue sharing in the U.S. All indicators of principal versus agent reporting under U.S. GAAP have been considered in analyzing the appropriate presentation of UTP Plan revenue sharing. However, the following are the primary indicators of net reporting:

• We are the administrator for the UTP Plan, in addition to being a participant in the UTP Plan. In our unique role as administrator, we facilitate the collection and dissemination of revenues on behalf of the UTP Plan participants. As a participant, we share in the net distribution of revenues according to the plan on the same terms as all other plan participants.

• The operating committee of the UTP Plan, which is comprised of representatives from each of the participants, including us solely in our capacity as a UTP Plan participant, is responsible for setting the level of fees to be paid by distributors and subscribers and taking action in accordance with the provisions of the UTP Plan, subject to SEC approval.

• Risk of loss on the revenue is shared equally among plan participants according to the UTP Plan.

The exchanges that comprise Nasdaq Nordic and Nasdaq Baltic do not have any market data products revenue sharing agreements.

Index

We develop and license Nasdaq branded indexes, associated derivatives and financial products as part of our Global Index Family. We also provide index data products and custom calculation services for third-party clients. Revenues primarily include license fees from these branded indexes, associated derivatives and financial products in the U.S. and abroad. We primarily have two types of license agreements: transaction-based licenses and asset-based licenses. Transaction-based licenses are generally renewable agreements. Customers are charged based on transaction volume or a minimum contract amount, or both. If a customer is charged based on transaction volume, we recognize revenue when the transaction occurs. If a customer is charged based on a minimum contract amount, we recognize revenue on a pro-rata basis over the licensing term since the customer receives and consumes the benefit as Nasdaq provides the service. Asset-based licenses are also generally renewable agreements. Customers are charged based on a percentage of assets under management for licensed products, per the agreement, on a monthly or quarterly basis. These revenues are recognized over the term of the license agreement since the customer receives and consumes the benefit as Nasdaq provides the service. Revenue from index data subscriptions are recognized on a monthly basis.

Investment Data & Analytics

Investment data & analytics revenues are earned from leading investment content and analytics products. We earn revenues primarily based on the number of content and analytics subscribers and distributors of our content and analytics.

These subscription agreements are generally annual in term, payable in advance, and provide for automatic renewal. Subscription-based revenues are recognized over time on a ratable basis over the contract period beginning on the date that our service is made available to the customer since the customer receives and consumes the benefit as Nasdaq provides the service.

Market Technology

Market Technology provides technology solutions for trading, clearing, settlement, surveillance and information dissemination, as well as risk management solutions. Revenues primarily consist of software, license and support revenues, change request and advisory revenues, and software as a service revenues.

In our Market Technology business, we enter into long-term contracts with customers to develop customized technology solutions, license the right to use software, and provide post-contract support and other services to our customers. We also enter into agreements to modify the system solutions sold by Nasdaq after delivery has occurred. In addition, we enter into subscription agreements which allow customers to connect to our servers to access our software.

Our long-term contracts with customers to develop customized technology solutions, license the right to use software and provide post-contract support and other services to our customers have multiple performance obligations. The performance obligations are generally: 1) software license and installation service and 2) software support. We have determined that the software license and installation service are not distinct as the license and the customized installation service are inputs to produce the combined output, a functional and integrated software system.

For contracts with multiple performance obligations, we allocate the contract transaction price to each performance obligation using our best estimate of the standalone selling price of each distinct good or service in the contract. In instances where standalone selling price is not directly observable, such as when we do not sell the product or service separately, we determine the standalone selling price predominately through an expected cost plus a margin approach.

Contract modifications are routine in the performance of our contracts. Contracts are often modified to account for changes in contract specifications or requirements. In most instances, contract modifications are for goods and services that are not distinct, and, therefore, are accounted for as part of the existing contract.

For our long-term contracts, payments are generally made throughout the contract life and can be dependent on either reaching certain milestones or paid upfront in advance of the service period depending on the stage of the contract. For subscription agreements, contract payment terms can be quarterly, annually or monthly, in advance. For all other contracts, payment terms vary.

We generally recognize revenue over time as our customers simultaneously receive and consume the benefits provided by our performance because our customer controls the asset for which we are creating, our performance does not create an asset with alternative use, and we have a right to payment for performance completed to date. For these services, we recognize revenue over time using costs incurred to date relative to total estimated costs at completion to measure progress toward satisfying our performance obligation. Incurred costs represent work performed, which corresponds with, and thereby depicts, the transfer of control to the customer. Contract costs generally include labor and overhead. For software support and update services, and for subscription agreements which allow customers to connect to our servers to access our software, we generally recognize revenue ratably over the service period beginning on the date our service is made available to the customer since the customer receives and consumes the benefit consistently over the period as Nasdaq provides the services.

Accounting for our long-term contracts requires judgment relative to assessing risks and their impact on the estimate of revenues and costs. Our estimates are impacted by factors such as the potential for schedule and technical issues, productivity, and the complexity of work performed. When adjustments in estimated total contract costs are required, any changes in the estimated revenues from prior estimates are recognized in the current period for the effect of such change. If estimates of total costs to be incurred on a contract exceed estimates of total revenues, a provision for the entire estimated loss on the contract is recorded in the period in which the loss is determined.

Other Revenues

Other revenues include the revenues from the Public Relations Solutions and Digital Media Services businesses which were sold in April 2018. Prior to the sale date, these revenues were included in our Corporate Solutions business and were primarily transaction-based revenues.

Revenue From Contracts With Customers

On January 1, 2018, we adopted Topic 606 using the full retrospective method. The adoption of Topic 606 impacted the revenue and expense recognition for our Market Technology business and revenue recognition for our Listing Services business. However, the adoption of Topic 606 did not have a material impact on our consolidated financial statements at the time of adoption or in any prior reporting periods. There was no impact to revenue and expense recognition for our other businesses. Additional disclosures required by Topic 606 are provided below.

Contract Balances

Substantially all of our revenues are considered to be revenues from contracts with customers. The related accounts receivable balances are recorded in our Condensed Consolidated Balance Sheets as receivables which is net of allowance for doubtful accounts of $13 million as of June 30, 2018 and $9 million as of December 31, 2017. The changes in the balance between periods were immaterial. We do not have obligations for warranties, returns or refunds to customers.

For the majority of our contracts with customers, except for our market technology and listings services contracts, our performance obligations are short-term in nature and there is no significant variable consideration.

We do not have significant revenues recognized from performance obligations that were satisfied in prior periods. We have elected not to provide disclosures about transaction price allocated to unsatisfied performance obligations if contract durations are less than one year. For contract durations that are one-year or greater, we do not have a material portion of transaction price allocated to unsatisfied performance obligations that are not included in deferred revenue other than for our market technology contracts which are discussed below under “Market Technology.” Deferred revenue primarily represents our contract liabilities related to our fees for annual and initial listings, market technology, corporate solutions and information services contracts. Deferred revenue is the only significant contract asset or liability impacted by our adoption of Topic 606. See Note 8, “Deferred Revenue,” for our discussion on deferred revenue balances, activity, and expected timing of recognition. See “Revenue Recognition” below for further descriptions of our revenue contracts.

Sales commissions earned by our sales force are considered incremental and recoverable costs of obtaining a contract with a customer. These costs are deferred and amortized on a straight-line basis over the period of benefit that we have determined to be the contract term or estimated service periods. Sales commissions for renewal contracts are deferred and amortized on a straight-line basis over the related contractual renewal period. Amortization expense is included in compensation and benefits expense in the Condensed Consolidated Statements of Income. The balance of deferred costs and related amortization expense are not material to our consolidated financial statements. We elected the practical expedient of recognizing sales commissions as an expense when incurred if contract durations are one year or less. We also have elected the practical expedient of excluding sales taxes from transaction prices.

Certain judgments and estimates were used in the identification and timing of satisfaction of performance obligations and the related allocation of transaction price and are discussed below. We believe that these represent a faithful depiction of the transfer of services to our customers.

Revenue Recognition

Our primary revenue contract classifications are described below. Though we discuss additional revenue details in our “Management's Discussion and Analysis of Financial Condition and Results of Operations,” the categories below best represent those that depict similar economic characteristics of the nature, amount, timing and uncertainty of our revenues and cash flows.

Market Services

Transaction-Based Trading and Clearing

Transaction-based trading and clearing includes equity derivative trading and clearing revenues, cash equity trading revenues and FICC revenues. Nasdaq charges transaction fees for trades executed on our exchanges, as well as on orders that are routed to and executed on other market venues. Nasdaq charges clearing fees for contracts cleared with Nasdaq Clearing.

In the U.S., transaction fees are based on trading volumes for trades executed on our U.S. exchanges and in Europe, transaction fees are based on the volume and value of traded and cleared contracts. In Canada, transaction fees are based on trading volumes for trades executed on our Canadian exchange.

Nasdaq satisfies its performance obligation for trading services upon the execution of a customer trade and clearing services when a contract is cleared, as trading and clearing transactions are substantially complete when they are executed and we have no further obligation to the customer at that time. Transaction-based trading and clearing fees can be variable and are based on trade volume tiered discounts. Transaction revenues, as well as any tiered volume discounts, are calculated and billed monthly in accordance with our published fee schedules. In the U.S., we also pay liquidity payments to customers based on our published fee schedules. We use these payments to improve the liquidity on our markets and therefore recognize those payments as a cost of revenue.

The majority of our FICC trading and clearing customers are charged transaction fees, as discussed above, which are based on the volume and value of traded and cleared contracts. We also enter into annual fixed contracts with customers trading U.S. Treasury securities. The customers are charged an annual fixed fee which is billed per the agreement, on a monthly or quarterly basis. Revenues earned on fixed contracts are recognized over time on a ratable basis over the contract period beginning on the date that our service is made available to the customer since the customer receives and consumes the benefit as Nasdaq provides the service.

For U.S. equity derivative trading, we credit a portion of the per share execution charge to the market participant that provides the liquidity. For U.S. cash equity trading, for Nasdaq and Nasdaq PSX, we credit a portion of the per share execution charge to the market participant that provides the liquidity and for Nasdaq BX, we credit a portion of the per share execution charge to the market participant that takes the liquidity. We record these credits as transaction rebates that are included in transaction-based expense in the Condensed Consolidated Statements of Income. These transaction rebates are paid on a monthly basis and the amounts due are included in accounts payable and accrued expenses in the Condensed Consolidated Balance Sheets.

In the U.S., we pay Section 31 fees to the SEC for supervision and regulation of securities markets. We pass these costs along to our customers through our equity derivative trading and clearing fees and our cash equity trading fees. We collect the fees as a pass-through charge from organizations executing eligible trades on our options exchanges and our cash equity platforms and we recognize these amounts in transaction-based expenses when incurred. Section 31 fees received are included in cash and cash equivalents in the Condensed Consolidated Balance Sheets at the time of receipt and, as required by law, the amount due to the SEC is remitted semiannually and recorded as Section 31fees payable to the SEC in the Condensed Consolidated Balance Sheets until paid. Since the amount recorded as revenues is equal to the amount recorded as transaction-based expenses, there is no impact on our revenues less transaction-based expenses. As we hold the cash received until payment to the SEC, we earn interest income on the related cash balances.

Under our Limitation of Liability Rule and procedures, we may, subject to certain caps, provide compensation for losses directly resulting from the systems’ actual failure to correctly process an order, quote, message or other data into our platform. We do not record a liability for any potential claims that may be submitted under the Limitation of Liability Rule unless they meet the provisions required in accordance with U.S. GAAP. As such, losses arising as a result of the rule are accrued and charged to expense only if the loss is probable and estimable.

Other Revenues

Other revenues include the revenues from the Public Relations Solutions and Digital Media Services businesses which were sold in April 2018. Prior to the sale date, these revenues were included in our Corporate Solutions business and were primarily transaction-based revenues.

Equity Securities

Equity Securities

On January 1, 2018, we adopted ASU 2016-01 which requires that investments in equity securities (excluding equity method investments) be measured at fair value with changes in fair value recognized in net income. Equity securities are no longer classified as trading or available for sale.

We elected the measurement alternative for equity securities which were historically accounted for under the cost method of accounting. Since these equity securities do not have readily determinable fair values, they are measured at cost, less any impairment, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. We evaluate these securities for impairment by considering a variety of factors such as the earnings capacity of the investment. If a qualitative assessment indicates that the security is impaired, Nasdaq will estimate the fair value of the security, and if the fair value is less than the carrying amount of the security, recognize an impairment loss in net income equal to the difference between the carrying amount and fair value. There was no impact on our condensed consolidated financial statements as a result of this change.

The guidance for classifying and measuring investments in debt securities is unchanged. Therefore, changes in debt securities classified as trading securities are included in dividend and investment income in the Condensed Consolidated Statements of Income and debt securities classified as available-for-sale investment securities are carried at fair value with unrealized gains and losses, net of tax, reported in accumulated other comprehensive loss within stockholders’ equity in the Condensed Consolidated Balance Sheets. Realized gains and losses on these securities are included in earnings upon disposition of the securities using the specific identification method. In addition, realized losses are recognized when management determines that a decline in value is other than temporary, which requires judgment regarding the amount and timing of recovery. For financial investments that are classified as available-for-sale securities, we also consider the extent to which cost exceeds fair value, the duration of that difference, management’s judgment about the issuer’s current and prospective financial condition, as well as our intent and ability to hold the security until recovery of the unrealized losses.

Schedule of the Recent Accounting Pronouncements

Recent Accounting Pronouncements

Accounting Standard	Description	Effective Date	Effect on the Financial Statements or Other Significant Matters
Income Statement - Reporting Comprehensive Income In February 2018, the FASB issued ASU 2018-02, “Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (Topic 220).”	This ASU provides an election to reclassify tax effects that are stranded in accumulated other comprehensive income as a result of tax reform to retained earnings. An election is also available to reclassify other stranded tax effects that relate to the Tax Cuts and Jobs Act but do not directly relate to the change in the federal rate. Tax effects that are stranded in accumulated other comprehensive income for other reasons (e.g., prior changes in tax law, a change in valuation allowance) may not be reclassified. Previously, the effects of changes in tax rates and laws on deferred tax balances were required to be recorded as a component of tax expense related to continuing operations for the period in which the law was enacted, even if the assets and liabilities related to items of accumulated other comprehensive income. In other words, backward tracing of the income tax effects of items originally recognized through accumulated other comprehensive income was prohibited.	January 1, 2019, with early adoption permitted. We early adopted this standard on January 1, 2018.	As a result of the adoption of this standard, in the first quarter of 2018, we recorded a reclassification of $142 million for stranded tax effects related to the Tax Cuts and Jobs Act from accumulated other comprehensive loss to retained earnings within stockholders’ equity in the Condensed Consolidated Balance Sheets. See Note 17, “Income Taxes,” for further discussion.
Goodwill In January 2017, the FASB issued ASU 2017-04, “Simplifying the Test for Goodwill Impairment.”	This ASU simplifies how an entity is required to test goodwill for impairment and removes the second step of the goodwill impairment test, which required a hypothetical purchase price allocation if the fair value of a reporting unit is less than its carrying amount. Goodwill impairment will now be measured using the difference between the carrying amount and the fair value of the reporting unit and the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. The amendments in this ASU should be applied on a prospective basis.	January 1, 2020, with early adoption permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017.	We do not anticipate a material impact on our consolidated financial statements at the time of adoption of this new standard as the carrying amounts of our reporting units have been less than their corresponding fair values in recent years. Therefore, the second step of the goodwill impairment test was not required. However, changes in future projections, market conditions and other factors may cause a change in the excess of fair value of our reporting units over their corresponding carrying amounts. We do not anticipate early adoption of this standard.
Financial Instruments - Credit Losses In June 2016, the FASB issued ASU 2016-13, “Measurement of Credit Losses on Financial Instruments.”	This ASU changes the impairment model for certain financial instruments. The new model is a forward looking expected loss model and will apply to financial assets subject to credit losses and measured at amortized cost and certain off-balance sheet credit exposures. This includes loans, held-to-maturity debt securities, loan commitments, financial guarantees and net investments in leases, as well as trade receivables. For available-for-sale debt securities with unrealized losses, credit losses will be measured in a manner similar to today, except that the losses will be recognized as allowances rather than reductions in the amortized cost of the securities.	January 1, 2020, with early adoption permitted as of January 1, 2019.	We are currently assessing the impact that this standard will have on our consolidated financial statements. We do not anticipate early adoption of this standard.

Accounting Standard	Description	Effective Date	Effect on the Financial Statements or Other Significant Matters
Leases In February 2016, the FASB issued ASU 2016-02, “Leases.”	Under this ASU, at the commencement date, lessees will be required to recognize a lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis; and a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. This guidance is not applicable for leases with a term of 12 months or less. Recognition, measurement and presentation of expenses will depend on classification as a finance or operating lease. The guidance also requires certain quantitative and qualitative disclosures about leasing arrangements. Lessor accounting is largely unchanged. In transition, lessees and lessors are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach.	January 1, 2019, with early adoption permitted.	See discussion below.
