Summary of Significant Accounting Policies	12 Months Ended

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation The accompanying consolidated financial statements are presented in accordance with U.S. generally accepted accounting principles, or U.S. GAAP. The consolidated financial statements include our wholly-owned and controlled subsidiaries. All intercompany balances and transactions between our wholly-owned and controlled subsidiaries have been eliminated in consolidation. As discussed in Note 3, we completed several acquisitions during the years ended December 31, 2016 , 2015 and 2014 and have included the financial results of these companies in the consolidated financial statements effective from the respective acquisition dates. As discussed in Note 16, we completed the initial public offering, or IPO, of our wholly-owned subsidiary Euronext N.V., or Euronext, in June 2014 and completed the sales of Wombat in July 2014 and NYFIX and Metabit in September 2014, and have included the financial results of these companies in discontinued operations in the consolidated financial statements. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires our management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements. Estimates also affect the reported amounts of revenues and expenses during the reporting period. Actual amounts could differ from those estimates. Comprehensive Income Other comprehensive income includes changes in unrealized gains and losses on financial instruments classified as available-for-sale, changes in fair value of net investment hedges, foreign currency translation adjustments, income from equity method investments, and amortization of the difference in the projected benefit obligation and the accumulated benefit obligation associated with benefit plan liabilities, net of tax. Non-controlling Interest For those consolidated subsidiaries in which our ownership is less than 100% and for which we have control over the assets and liabilities and the management of the entity, the outside stockholders’ interests are shown as non-controlling interests. For instances where outside stockholders’ hold an option to require us to repurchase the outside stockholders’ interest, these interests are shown as redeemable non-controlling interests. Segment and Geographic Information We operated as a single reportable business segment as of December 31, 2015 but began operating as two operating segments in the first quarter of 2016 following our acquisition of Interactive Data. As of December 31, 2016 , we continue to operate as two business segments: our Trading and Clearing segment and our Data and Listings segment. This presentation is reflective of how our chief operating decision maker reviews and operates our business. Our Trading and Clearing segment comprises our transaction-based execution and clearing businesses. Our Data and Listings segment comprises our subscription-based data services and securities listings businesses. The majority of our identifiable assets are located in the U.S. and U.K. Cash and Cash Equivalents We consider all short-term, highly liquid investments with original maturities at the purchase date of three months or less to be cash equivalents. Short-Term and Long-Term Restricted Cash and Investments We classify all cash and cash equivalents and investments that are not available for immediate or general business use by us as restricted in the accompanying consolidated balance sheets (Note 4). The restricted cash would include cash set aside due to regulatory requirements, earmarked for specific purposes, or restricted by specific agreements. Short-Term and Long-Term Investments We periodically invest a portion of our cash in excess of short-term operating needs in term deposits and investment-grade marketable debt securities, including government or government sponsored agencies and corporate debt securities (Note 5). These investments are classified as available-for-sale in accordance with U.S. GAAP. We do not have any investments classified as held-to-maturity or trading. Additionally, we classify equity and fixed income mutual funds, held for the purpose of providing future payments for the supplemental executive savings plan and a component of the supplemental executive retirement plan, as available-for-sale securities. Available-for-sale investments are carried at their fair value using primarily quoted prices in active markets for identical securities, with unrealized gains and losses, net of deferred income taxes, reported as a component of accumulated other comprehensive income. Realized gains and losses, and declines in value deemed to be other-than-temporary on available-for-sale investments, are recognized currently in earnings. The cost of securities sold is based on the specific identification method. Investments that we intend to hold for more than one year are classified as long-term investments in the accompanying consolidated balance sheets. Cost and Equity Method Investments We use the cost method to account for a non-marketable equity investment in an entity that we do not control and for which we do not have the ability to exercise significant influence over an entity’s operating and financial policies. When we do not have a controlling financial interest in an entity but exercise significant influence over the entity's operating and financial policies, such investment is accounted for using the equity method. We account for our investments in MERSCORP Holdings, Inc., or MERS, and Options Clearing Corporation, or OCC, as equity method investments. We recognized $25 million , $6 million and $25 million in equity income related to these investments during the years ended December 31, 2016 , 2015 and 2014 , respectively, as other income. We recognize dividend income when declared as a reduction in the carrying value of our equity method investments. Cost and equity method investments were $208 million and $116 million as of December 31, 2016 and 2015 , respectively, and are classified as other non-current assets in the accompanying consolidated balance sheets. The increase in the cost and equity method investments during the year ended December 31, 2016 is primarily due to our investment in MERS. Margin Deposits and Guaranty Funds Original margin, variation margin and guaranty funds held by our clearing houses for clearing members may be in the form of cash, government obligations, certain agency and corporate debt or gold (Note 12). Cash original margin, variation margin and guaranty fund deposits are reflected in the accompanying consolidated balance sheets as current assets and current liabilities. The amount of margin deposits on hand will fluctuate over time as a result of, among other things, the extent of open positions held at any point in time by market participants in contracts and the margin rates then in effect for such contracts. Non-cash original margin and guaranty fund deposits are not reflected in the accompanying consolidated balance sheets as the risks and rewards of these assets remain with the clearing members unless the clearing houses have sold or re-pledged the assets or in the event of a clearing member default, where the clearing member is no longer entitled to redeem the assets. Any income, gain or loss accrues to the clearing members. Property and Equipment Property and equipment is recorded at cost, reduced by accumulated depreciation (Note 6). Depreciation and amortization expense related to property and equipment is computed using the straight-line method based on estimated useful lives of the assets, or in the case of leasehold improvements, the shorter of the initial lease term or the estimated useful life of the improvement. We review the remaining estimated useful lives of our property and equipment at each balance sheet date and will make adjustments to the estimated remaining useful lives whenever events or changes in circumstances indicate that the remaining useful lives have changed. Gains on disposals of property and equipment are included in other income and losses on disposals of property and equipment are included in depreciation expense. Maintenance and repair costs are expensed as incurred. Allowance for Doubtful Accounts The allowance for doubtful accounts is maintained at a level that we believe to be sufficient to absorb probable losses in our accounts receivable portfolio. The allowance is based on several factors, including a continuous assessment of the collectability of each account. In circumstances where a specific customer's inability to meet its financial obligations is known, we record a specific provision for bad debts against amounts due to reduce the receivable to the amount we reasonably believe will be collected. Accounts receivable are written off against the allowance for doubtful accounts when collection efforts cease. A reconciliation of the beginning and ending amount of allowance for doubtful accounts is as follows for the years ended December 31, 2016 , 2015 and 2014 (in millions): Year Ended December 31, 2016 2015 2014 Beginning balance of allowance for doubtful accounts $ 2 $ 1 $ 1 Bad debt expense 5 2 1 Charge-offs — (1 ) (1 ) Ending balance of allowance for doubtful accounts $ 7 $ 2 $ 1 Bad debt expense in the table above is based on our historical collection experiences and our assessment of the collectability of specific accounts. Charge-offs in the table above represent the write-off of uncollectible receivables, net of recoveries. These lines also include the impact of foreign currency translation adjustments. Software Development Costs We capitalize costs, both internal and external direct and incremental costs, related to software developed or obtained for internal use in accordance with U.S. GAAP . Software development costs incurred during the preliminary or maintenance project stages are expensed as incurred, while costs incurred during the application development stage are capitalized and are amortized using the straight-line method over the useful life of the software, not to exceed three years (except for Interactive Data's and NYSE's new platforms, which have eight year useful lives). Amortization of these capitalized costs begins only when the software becomes ready for its intended use. General and administrative costs related to developing or obtaining such software are expensed as incurred. Accrued Employee Benefits We have a defined benefit pension plan and other postretirement benefit plans, or collectively the “benefit plans”, covering certain of our U.S. operations. The benefit accrual for the pension plan is frozen. We recognize the funded status of the benefit plans in the consolidated balance sheets, measure the fair value of plan assets and benefit obligations as of the date of our fiscal year-end, and provide additional disclosures in the footnotes to the consolidated financial statements (Note 14). Benefit plan costs and liabilities are dependent on assumptions used in calculating such amounts. These assumptions include discount rates, health care cost trend rates, benefits earned, interest cost, expected return on assets, mortality rates and other factors. Actual results that differ from the assumptions are accumulated and amortized over future periods and, therefore, generally affect recognized expense and the recorded obligation in future periods. We immediately recognize in the consolidated statements of income certain of these unrecognized amounts when triggering events occur, such as when a settlement of pension obligations in excess of total interest and service costs occurs. While we believe that the assumptions used are appropriate, differences in actual experience or changes in assumptions may affect our pension and other post-retirement obligations and future expense recognized. Goodwill and Indefinite-Lived Intangible Assets Goodwill represents the excess of the purchase price of our acquisitions over the fair value of identifiable net assets acquired, including other identified intangible assets (Note 7). We recognize specifically identifiable intangibles when a specific right or contract is acquired. Goodwill has been allocated to reporting units for purposes of impairment testing based on the portion of synergy, cost savings and other expected future cash flows expected to benefit the reporting units at the time of the acquisition. We test our goodwill for impairment at the reporting unit level. The reporting units identified for our goodwill testing are the futures, data and listings, cash and CDS reporting units. Goodwill impairment testing is performed annually in the fiscal fourth quarter or more frequently if conditions exist that indicate that the asset may be impaired. We also evaluate indefinite-lived intangible assets for impairment annually in our fiscal fourth quarter or more frequently if conditions exist that indicate that the asset may be impaired. Such evaluation includes either applying the optional qualitative screen to determine if it is not more likely than not that the fair value of the asset continues to exceed its carrying value or determining the fair value of the asset and comparing the fair value of the asset to its carrying value. If the fair value of the indefinite-lived intangible asset is less than its carrying value, an impairment loss is recognized in an amount equal to the difference. For both goodwill and indefinite lived impairment testing, we have the option to first perform a qualitative assessment to determine whether it is more likely than not that the fair value of a reporting unit or indefinite lived intangible asset is less than its carrying amount. If we conclude that this is the case, we must perform additional testing of the asset or reporting unit. Otherwise, no further testing is necessary. We did not record an impairment charge related to goodwill or indefinite lived intangible assets during the years ended December 31, 2016 , 2015 or 2014 . Impairment of Long-Lived Assets and Finite-Lived Intangible Assets We review our property and equipment and finite-lived intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount may not be fully recoverable. To analyze recoverability, we project undiscounted net future cash flows over the remaining life of such assets. If these projected cash flows are less than the carrying amount, an impairment indicator would exist. The impairment loss is measured based upon the difference between the carrying amount and the fair value of the assets. Finite-lived intangible assets are generally amortized on a straight-line basis or using an accelerated method over the lesser of their contractual or estimated useful lives. In August 2016, we sold certain of Creditex’s U.S. voice brokerage operations to Tullett Prebon. During the third quarter of 2016, we discontinued Creditex’s U.K. voice brokerage operations and an impairment of the asset was recorded as amortization expense in September 2016 for $33 million (Note 7). Derivatives and Hedging Activity We may use derivative instruments to limit exposure to changes in foreign currency exchange rates. All derivatives are required to be recorded at fair value in the accompanying consolidated balance sheets. Changes in the fair value of such derivative financial instruments are recognized in net income as they are not designated as hedges under U.S. GAAP. From time to time, we may hedge the foreign currency translation of certain net investments by designating all or a portion of certain financial liabilities denominated in the same currency in accordance with U.S. GAAP. We entered into foreign currency hedging transactions during years ended December 31, 2016 , 2015 and 2014 as economic hedges to help mitigate a portion of our foreign exchange risk exposure. During the year ended December 31, 2014, we recognized a loss of $21 million as a component of income from discontinued operations upon discontinuance of the net investment hedge in connection with the IPO of Euronext. Intellectual Property All costs related to internally developed patents and trademarks are expensed as incurred. All costs related to purchased patents, trademarks and internet domain names are recorded as other intangible assets and are amortized on a straight-line basis over their estimated useful lives. All costs related to licensed patents are capitalized and amortized on a straight-line basis over the term of the license. Income Taxes We recognize income taxes under the liability method. We recognize a current tax liability or tax asset for the estimated taxes payable or refundable on tax returns for the current year. We recognize deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the financial statement carrying amounts and the tax bases of assets and liabilities. We establish valuation allowances if we believe that it is more likely than not that some or all of our deferred tax assets will not be realized. Deferred tax assets and liabilities are measured using current enacted tax rates in effect. We do not recognize a tax benefit unless we conclude that it is more likely than not that the benefit will be sustained on audit by the taxing authority based solely on the technical merits of the associated tax position. If the recognition threshold is met, we recognize a tax benefit measured at the largest amount of the tax benefit that, in our judgment, is greater than 50 percent likely to be realized. We recognize accrued interest and penalties related to uncertain tax positions as a component of income tax expense. We are subject to tax in numerous domestic and foreign jurisdictions primarily based on our operations in these jurisdictions. Significant judgment is required in assessing the future tax consequences of events that have been recognized in our financial statements or tax returns. Fluctuations in the actual outcome of these future tax consequences could have a material impact on our financial position or results of operations. Revenue Recognition We recognize revenue when persuasive evidence of an arrangement exists, delivery has occurred, the sale price is fixed or determinable and collectability is reasonably assured. Our revenues primarily consist of transaction and clearing fee revenues for transactions executed and/or cleared through our global electronic derivatives trading and clearing platforms and cash equities trading and revenues related to our data services fees and listing fees. We also evaluate all contracts in order to determine appropriate gross versus net revenue reporting. Derivatives trading and clearing revenues are recognized over the period in which the services are provided, which is typically the date the transactions are executed or are cleared, except for a portion of clearing revenues related to cleared contracts which have an ongoing clearing obligation that extends beyond the execution date. The transaction and clearing fee revenues are determined on the basis of the transaction and clearing fee charged for each contract traded on the exchanges. Derivatives transaction and clearing fees are recorded net of rebates of $674 million , $563 million and $466 million for the years ended December 31, 2016 , 2015 and 2014 , respectively. We offer rebates in certain of our markets primarily to support market liquidity and trading volume by providing qualified participants in those markets a discount to the applicable commission rate. Such rebates are calculated based on volumes traded. The increase in the rebates is due primarily to an increase in the number of participants in the rebate programs offered on various contracts, an increase in our traded volume and an increase in the number of rebate programs. Cash trading fee revenues are paid by organizations based on their trading activity. Fees are assessed on a per share basis for trading in equity securities. The fees are applicable to all transactions that take place on any of our equity trading venues, and the fees vary based on the size and type of trade that is consummated and trading venue. The equity trading venues earn transaction fees for customer orders of equity securities matched internally, as well as for customer orders routed to other exchanges. Cash trading fees are recognized as earned, which is generally upon execution of the trade. Cash trading fees are recorded gross of liquidity rebates and routing charges. Liquidity payments made to cash and options trading customers and routing charges made to other exchanges are included in transaction-based expenses in the consolidated statements of income. Listings revenues consist of original listing fees paid by issuers to list the initial securities on the various cash markets, other listing fees related to other corporate actions (including stock splits, sales of additional securities and merger and acquisitions), annual listing fees paid by companies whose financial instruments are listed on the cash markets, and other services provided to our listed companies and other companies. Original listing fees are assessed primarily based on the number of shares that the issuer initially lists. Original listing fees are recognized as revenue on a straight-line basis over the estimated service periods ranging from 5 to 9 years. Other corporate action listing fees are recognized as revenue on a straight-line basis over the estimated service periods ranging from 3 to 6 years. The service periods are determined separately for each of our listing venues (Note 8). Annual listing fees are billed at the beginning of the year and are recognized on a pro rata basis over the calendar year. Data services revenues in our derivatives markets primarily include terminal and license fees received from data vendors in exchange for the provision of real-time futures price information and market data access fees. Market data fees are charged to data vendors on a monthly basis based on the number and type of terminals they have carrying futures data. Each data vendor also pays an annual license fee, which is deferred and recognized as revenue ratably over the period of the annual license. Data services revenues also include market data access fees charged to customers that trade on the electronic platform. The market data access amount for each company is based on the number of users at each company trading on the electronic platform. Monthly trading commissions are recognized as transaction and clearing fee revenues. Any customer's market data access fees in excess of that customer's commissions on trading activity are recognized as market data access revenues. We collect market data revenues from our cash equity and options consortium-based data products and, to a lesser extent, for New York Stock Exchange proprietary data products. Consortium-based data fees are determined by securities industry plans. Consortium-based data revenues that coordinated market data distribution generates (net of administration costs) are distributed to participating markets on the basis of the Regulation NMS formula. We collect annual license fees from vendors for the right to distribute market data to third parties and a service fee from vendors for direct connection to market data. These fees are recognized as revenue as services are rendered. We also charge customers for accessing our data services through Secure Financial Transaction Infrastructure, or SFTI, and colocation services. SFTI is a physical network infrastructure that connects our markets and other major market centers with market participants and allows those participants to receive data feeds. Data analytics includes a number of products such as forward curves, index and valuation services. Revenue for subscription based contracts is recognized ratably over the life of the contract and revenue for usage based contracts is recognized in the month that the products/services are provided. Certain of our businesses collect fees for installation/set-up services which, if deemed a separate deliverable with standalone value, are recognized upon delivery as long as the remaining criteria for recognition of revenue have been achieved. Revenue for installation/set-up services, that do not meet the criteria for separation, is recognized ratably either over the contractual term or the expected client relationship life. Revenue for professional services is recognized as the services are provided. Revenue for hardware is recognized when installation is completed and the related services go-live. Some contracts include multiple elements for which we determine whether the various elements meet the applicable criteria to be accounted for as separate elements and makes estimates regarding the relative fair values. Revenue for elements that cannot be separated is recognized once the revenue recognition criteria for the entire arrangement have been met or over the period that our obligation to perform is fulfilled. Consideration for elements that are deemed separable is allocated to the separate elements at the inception of the arrangement on the basis of their relative selling price and recognized based on meeting authoritative criteria to do so. Other revenues primarily consist of various fees for services provided to our customers, including interest income on certain clearing margin deposits, regulatory penalties and fines, fees for use of our facilities, regulatory fees charged to member organizations of our U.S. securities exchanges, designated market maker service fees, exchange membership fees and agricultural grading and certification fees. These fees are recognized as revenue as services are rendered. Activity Assessment Fees and Section 31 Fees We pay the Securities and Exchange Commission, or SEC, fees pursuant to Section 31 of the Securities Exchange Act of 1934 for transactions executed on our U.S. equities and options exchanges. These Section 31 fees are designed to recover the costs to the government for supervising and regulating the securities markets and securities professionals. We (or the OCC on our behalf), in turn, collect activity assessment fees, which are included in transaction and clearing fees in the accompanying consolidated statements of income, from member organizations clearing or settling trades on the U.S. equities and options exchanges and recognize these amounts as revenue when invoiced. Fees received are included in cash at the time of receipt and, as required by law, the amount due to the SEC is remitted semi-annually and recorded as an accrued liability until paid. The activity assessment fees are designed so that they are equal to the Section 31 fees paid by us to the SEC. As a result, Section 31 fees do not have an impact on our net income. Stock-Based Compensation We currently sponsor employee and director stock option and restricted stock plans (Note 10). U.S. GAAP requires the measurement and recognition of compensation expenses for all share-based payment awards made to employees and directors, including employee stock options and restricted stock, based on estimated fair values. U.S. GAAP requires companies to estimate the fair value of stock option awards on the date of grant using an option-pricing model. The value of the portion of the award that is ultimately expected to vest is recognized as stock-based compensation expense over the requisite service period in our consolidated financial statements. We use the Black-Scholes option pricing model for purposes of valuing stock option awards. Our determination of fair value of stock option awards on the date of grant using the Black-Scholes option pricing model is affected by our stock price as well as assumptions regarding a number of subjective variables. These variables include interest rates, our expected dividend yield, our expected share price volatility over the term of the awards and actual and projected employee stock option exercise behavior. Stock Split On November 3, 2016, a 5-for-1 split of our common stock was effected in the form of a four share stock dividend per share of common stock to shareholders of record as of the close of market on October 27, 2016. The new shares began trading on a split-adjusted basis on November 4, 2016. All share and earnings per share information has been retroactively adjusted to reflect the stock split. We retired all of our outstanding treasury shares effective October 27, 2016, the record date. Treasury Stock We record treasury stock activities under the cost method whereby the cost of the acquired stock is recorded as treasury stock (Note 10). We retired all of our outstanding treasury shares effective October 27, 2016, the record date of the stock split mentioned above. Our accounting policy upon the formal retirement of treasury stock is to deduct the par value from common stock and to reflect any excess of cost over par value as a deduction from additional paid-in capital (to the extent created by previous issuances of the shares) and retained earnings. Credit Risk and Significant Customers Our clearing houses have credit risk for maintaining certain of the clearing member cash deposits at various financial institutions (Note 12). Cash deposit accounts are established at larger money center banks and structured to restrict the rights of offset or liens by the banks. Our clearing houses monitor the cash deposits and mitigate credit risk by keeping such deposits in several financial institutions, ensuring that its overall credit risk exposure to any individual financial institution remains within acceptable concentration limits, and by ensuring that the financial institutions have high investment grade ratings. We also limit our risk of loss by holding the majority of the cash deposits in high quality short-term sovereign debt reverse repurchase agreements with several different counterparty banks or direct investments in short-term high quality sovereign and supranational debt issues. While we seek to achieve a reasonable rate of return which may generate interest income for our clearing members, we are primarily concerned with preservation of capital and managing the risks associated with these deposits. As the clearing houses may pass on interest revenues, minus costs, to the members, this could include negative or reduced yield due to market conditions. When engaging in reverse repurchase agreements, our clearing houses take delivery of the underlying securities in custody accounts under clearing house control. Additionally, the securities purchased subject to reverse repurchase have a market value greater than the reverse repurchase amount. The typical haircut received for high quality sovereign debt is 2% of the reverse repurchase amount. Thus, in the event that a reverse repurchase counterparty defaults on its obligation to repurchase the underlying reverse repurchase securities, our clearing house will have possession of securities with a value potentially greater than the reverse repurchase counterparty’s obligation to the clearing house. ICE Clear Credit has been designated as a systemically important financial market utility by the Financial Stability Oversight Council and has been authorized to establish and maintain a cash account at the Federal Reserve Bank of Chicago. Such account was opened on July 30, 2015 and it is intended to decrease ICE Clear Credit's custodial, liquidity and operational risk as compared to alternative custodial and investment arrangements. Our futures businesses have minimal credit risk as all of their transaction revenues are currently cleared through our clearing houses. Our accounts receivable related to market data revenues, cash trading, listing revenues, technology revenues, CDS transaction revenues and bilateral over-the-counter energy transaction revenues subjects us to credit risk, as we do not require these customers to post collateral. We limit our risk of loss by terminating access to trade to entities with delinquent accounts. The concentration of risk on accounts receivable is also mitigated by the large number of entities comprising our customer base. Our accounts receivable are stated at cost. Excluding clearing members, there were no individual accounts receivable balances greater than 10% of total consolidated accounts receivable as of December 31, 2016 or December 31, 2015 . No single customer accounted for more than 10% of total consolidated revenues during any of the years ended December 31, 20

Business Combinations [Abstract]
Acquisitions	Acquisitions Securities Evaluations and Credit Market Analysis Acquisitions On October 3, 2016, we acquired from S&P Global 100% of Standard & Poor’s Securities Evaluations, Inc., or SPSE, and 100% of Credit Market Analysis for $431 million in cash. The cash consideration was funded from borrowings under our commercial paper program. SPSE, which has been renamed Securities Evaluations, is a provider of fixed income evaluated pricing and Credit Market Analysis is a provider of independent data for the OTC markets, including credit derivatives and bonds. Securities Evaluations and Credit Market Analysis are part of the suite of pricing and analytics products and services that comprise ICE Data Services. In order to comply with an Order of the Securities and Exchange Commission, services offered by Securities Evaluations will be managed and operated separately from the existing fixed income evaluated pricing services offered by ICE Data Services, including Interactive Data, until further notice. The acquisitions will enable us to offer customers new data and valuation services. The total purchase price was allocated to Securities Evaluations and Credit Market Analysis’ preliminary tangible and identifiable intangible assets and liabilities based on the estimated fair values of those assets as of October 3, 2016, as set forth below. The excess of the purchase price over the preliminary net tangible and identifiable intangible assets was recorded as goodwill and was recorded in our data and listing reporting unit. Goodwill represents potential revenue synergies related to new product development, expense synergies related to technology and opportunities to enter new markets. The preliminary purchase price allocation is as follows (in millions): Goodwill $ 307 Identifiable intangible assets 180 Other assets and liabilities, net 12 Deferred tax liabilities on identifiable intangible assets (68 ) Total purchase price $ 431 In performing the preliminary purchase price allocation, we considered, among other factors, the intended future use of acquired assets, analysis of historical financial performance and estimates of future performance of the Securities Evaluations and Credit Market Analysis businesses. We have not yet obtained all of the information related to the fair value of the acquired assets and liabilities related to the acquisition to finalize the purchase price allocation. The primary areas of the preliminary purchase price allocation that are not yet finalized relate to the valuation of the identifiable intangible assets, income taxes (including uncertain tax positions) and certain other tangible assets and liabilities. The allocation of the purchase price will be finalized upon the completion of the analysis of the acquired assets and liabilities during the year ended December 31, 2017. The following table sets forth the components of the preliminary intangible assets associated with the acquisitions as of December 31, 2016 (in millions, except years): Preliminary Intangible Assets Acquisition-Date Preliminary Fair Value Accumulated Amortization Net Book Value Useful Life (Years) Customer relationships $ 129 $ (2 ) $ 127 15 to 20 Data/databases 36 (1 ) 35 5 to 10 Developed technology 13 (1 ) 12 6 to 7 Non-compete agreements 2 — 2 3 Total $ 180 $ (4 ) $ 176 An average 19-year useful life for customer relationships has been estimated based on the projected economic benefits associated with these assets. The average 19-year estimated useful life represents the approximate point in the projection period in which a majority of the asset’s cash flows are expected to be realized based on assumed attrition rates. Data/databases represents the underlying current and historical market data relating to daily pricing, intraday pricing and the evaluations and reference data. Developed technology represents completed software related to internal and external software platforms. The customer relationship intangible asset was valued using the multi period excess earnings method, the data/databases intangible assets were valued using the replacement cost approach, the developed technology intangible asset was valued using the relief from royalty income approach, and the non-compete agreements were valued using the with and without method within the income approach. The intangible assets will be amortized using the straight-line method over their estimated useful lives. Interactive Data Acquisition On December 14, 2015, we acquired 100% of Interactive Data in a stock and cash transaction. The total purchase price was $5.6 billion comprised of cash consideration of $4.1 billion and 32.3 million shares of our common stock. The cash consideration is gross of $301 million of cash held by Interactive Data on the date of the acquisition. Of the cash consideration, $2.6 billion was paid to retire Interactive Data's outstanding debt (Note 9). The fair value of the shares issued was $1.6 billion based on the average share price of our common stock of $48.90 per share on December 14, 2015. The cash consideration was funded from $2.5 billion of net proceeds received on November 24, 2015 in connection with the offering of new senior notes and $1.6 billion of borrowing under our commercial paper program. We valued the shares issued for the acquisition using a volume-weighted average share price as the acquisition closed during the trading day on December 14, 2015. The acquisition has been accounted for as a purchase business combination. Interactive Data, now part of ICE Data Services, is a leading provider of financial market data, analytics and related trading solutions, serving the mutual fund, bank, asset management, hedge fund, securities and financial instrument processing and administration sectors. The acquisition builds on our global market data growth strategy by expanding the markets served, adding technology platforms and increasing new data and valuation services. Our combined company will offer customers efficiencies in accessing data on an integrated platform while serving the growing demand for data, analysis, valuation and connectivity globally. The total purchase price was allocated to Interactive Data’s tangible and identifiable intangible assets and liabilities based on the estimated fair values of those assets as of December 14, 2015, as set forth below. In performing the purchase price allocation, we considered, among other factors, the intended future use of acquired assets, analysis of historical financial performance and estimates of future performance of Interactive Data's business. The excess of the purchase price over the net tangible and identifiable intangible assets was recorded as goodwill and was assigned to the data and listings reporting unit. Goodwill represents potential revenue synergies related to new product development, expense synergies related to technology and opportunities to enter new markets. The purchase price allocation is as follows (in millions): Cash and cash equivalents $ 301 Goodwill 3,242 Identifiable intangible assets 2,883 Other assets and liabilities, net 259 Deferred tax liabilities on identifiable intangible assets (1,057 ) Total purchase price $ 5,628 The following table sets forth the components of the intangible assets associated with the acquisition as of December 31, 2016 (in millions, except years): Intangible Assets Acquisition-Date Fair Value Foreign Currency Translation Accumulated Amortization Net Book Value Useful Life (Years) Customer relationships $ 2,452 $ (67 ) $ (104 ) $ 2,281 20 to 25 Developed technology 168 (4 ) (26 ) 138 5 to 8 In-process research and development 129 (4 ) — 125 N/A Data/databases 109 (3 ) (28 ) 78 4 Trade names and trademarks 12 — (11 ) 1 2 Market data provider relationships 11 — (1 ) 10 20 Non-compete agreements 2 — (2 ) — 1 Total $ 2,883 $ (78 ) $ (172 ) $ 2,633 An average 25 -year useful life for customer relationships has been estimated based on the projected economic benefits associated with these assets. The customer relationship intangible asset was valued using the multi period excess earnings method, the market data provider relationships and data/databases intangible assets were valued using the replacement cost approach, the trade names and trademarks and the developed technology (including in-process research and development) intangible assets were valued using the relief from royalty income approach, and the non-compete agreements were valued using the with and without method within the income approach. The intangible assets will be amortized using the straight-line method over their estimated useful lives. Developed technology represents completed software related to internal and external software platforms. In-process research and development represents the value assigned to acquired research and development projects that, as of the acquisition date, had not established technological feasibility and had no alternative future use. The in-process research and development intangible assets are capitalized and accounted for as indefinite-lived intangible assets and are subject to impairment testing until completion or abandonment of the projects. Upon successful completion of each project and launch of the product, we will make a separate determination of useful life of the in-process research and development intangible assets and the related amortization will be recorded as an expense over the estimated useful life of the specific projects. For the year ended December 31, 2016 , $17 million of the in-process research and development has been moved to developed technology with a useful life of seven years. Data/databases represents the underlying current and historical market data relating to daily pricing, intraday pricing and the evaluations and reference data. Market data provider relationships represents the unique relationships that Interactive Data has with exchanges and brokers worldwide. Trayport Acquisition On December 11, 2015, we acquired 100% of Trayport in a stock transaction. The total purchase price was $620 million , comprised of 12.6 million shares of our common stock based on the average share price of our common stock of $49.05 per share on December 11, 2015. We valued the shares issued for the acquisition using a volume-weighted average share price as the acquisition closed during the trading day on December 11, 2015. The acquisition has been accounted for as a purchase business combination. Trayport is a software company that licenses its technology to serve exchanges, OTC brokers and traders to facilitate electronic and hybrid trade execution primarily in the energy markets. The transaction is expected to enable us to provide new technology and software-related services to our energy customers. The U.K. Competition and Markets Authority, or the CMA, undertook a review of our acquisition of Trayport under the merger control laws of the U.K. During the pendency of the review, we did not integrate Trayport into our existing business operations. On October 17, 2016, the CMA issued its findings and ordered a divestment of Trayport to remedy what the CMA indicated it believed to be a substantial lessening of competition in the supply of trade execution services and trade clearing services to energy traders in the European Economic Area. In November 2016, we filed an appeal to challenge the CMA’s decision. The outcome of the appeal is expected to be determined in 2017. If our appeal is successful, the matter will be sent back to the CMA for additional review. If our appeal is not successful, we will be forced to sell Trayport and there is no certainty of the price we could receive if a sale were required. The timing of a final decision is uncertain at this time. The functional currency of Trayport is the pound sterling, as this is the currency in which Trayport operates. The $620 million in Trayport net assets were recorded on our December 11, 2015 opening balance sheet at a pound sterling/U.S. dollar exchange rate of 1.5218 ( £407 million ). Because our consolidated financial statements are presented in U.S. dollars, we must translate the Trayport net assets into U.S. dollars at exchange rates in effect at the end of each reporting period. Therefore, increases or decreases in the value of the U.S. dollar against the pound sterling will affect the value of the Trayport balance sheet, with gains or losses included in the cumulative translation adjustment account, a component of equity. As of the result of the decrease in the pounds sterling/U.S. dollar exchange rate to 1.2336 as of December 31, 2016 , the portion of our equity attributable to the Trayport net assets in accumulated other comprehensive loss from foreign currency translation was $117 million as of December 31, 2016 . If we are required to sell Trayport, we would include the accumulated translation adjustment when computing the gain or loss from the sale. The total purchase price was allocated to Trayport’s tangible and identifiable intangible assets and liabilities based on the estimated fair values of those assets as of December 11, 2015, as set forth below. In performing the purchase price allocation, we considered, among other factors, the intended future use of acquired assets, analysis of historical financial performance and estimates of future performance of Trayport’s business. The excess of the purchase price over the net tangible and identifiable intangible assets was recorded as goodwill and was assigned to the data and listings reporting unit. Goodwill represents potential revenue synergies related to new product development and opportunities to enter new markets. The purchase price allocation is as follows (in millions): Goodwill 387 Identifiable intangible assets 274 Other assets and liabilities, net 9 Deferred tax liabilities on identifiable intangible assets (50 ) Total purchase price $ 620 The following table sets forth the components of the intangible assets associated with the acquisition as of December 31, 2016 (in millions, except years): Intangible Assets Acquisition-Date Fair Value Foreign Currency Translation Accumulated Amortization Net Book Value Useful Life (Years) Customer relationships $ 242 $ (45 ) $ (11 ) $ 186 20 Developed technology 14 (2 ) (3 ) 9 3 to 5 Trade names and trademarks 18 (4 ) — 14 Indefinite Total $ 274 $ (51 ) $ (14 ) $ 209 The customer relationships intangible asset was valued using the multi period excess earnings method, and the developed technology and the trade names and trademarks intangible assets were valued using the relief from royalty income approach. The intangible assets will be amortized using the straight-line method over their estimated useful lives, except for the trade names and trademarks, which have indefinite lives. A 20 -year useful life for customer relationships has been estimated based on the projected economic benefits associated with these assets. Developed technology represents completed software related to internal and external software platforms. Indefinite useful lives have been assigned for the Trayport trade names and trademarks based on their long history in the marketplace, their continued use following the acquisition, and their importance to the business and prominence in the industry. Pro Forma Information The financial information in the table below summarizes the combined results of operations of ICE, Interactive Data and Trayport, on a pro forma basis, as though the companies had been combined as of the beginning of the period presented. The pro forma financial information is presented for informational purposes only and is not indicative of the results of operations that would have been achieved if the acquisition had taken place at the beginning of the period presented. Such pro forma financial information is based on the historical financial statements of ICE, Interactive Data and Trayport. This pro forma financial information is based on estimates and assumptions that have been made solely for purposes of developing such pro forma information, including, without limitation, purchase accounting adjustments. The pro forma financial information does not reflect any synergies or operating cost reductions that have been and may be achieved from the combined operations. The pro forma financial information combines the historical results for us and Interactive Data and Trayport for the years ended December 31, 2015 and 2014 in the following table (in millions, except per share amounts). Year Ended December 31, 2015 2014 Total revenues, less transaction-based expenses $ 4,308 $ 4,097 Operating income 1,997 1,700 Income from continuing operations attributable to ICE 1,379 1,085 Income from discontinued operations, net of tax — 11 Net income attributable to ICE 1,379 1,096 Basic earnings per common share: Continuing operations $ 2.30 $ 1.76 Discontinued operations — 0.02 Basic earnings per share $ 2.30 $ 1.78 Diluted earnings per share Continuing operations $ 2.29 $ 1.76 Discontinued operations — 0.02 Diluted earnings per share $ 2.29 $ 1.78 Other Acquisitions On June 30, 2016, we acquired a majority equity position in MERS, owner of Mortgage Electronic Registrations Systems, Inc. MERS is a privately held, member-based organization that owns and manages the MERS® System and is made up of thousands of lenders, servicers, sub-servicers, investors and government institutions. In addition, we have entered into a software development agreement to rebuild the MERS® System to benefit the U.S. residential mortgage finance market. The MERS® System is a national electronic registry that tracks the changes in servicing rights and beneficial ownership interests in U.S.-based mortgage loans. The terms of the MERS acquisition include a right for us to purchase all of the remaining equity interests of MERS after we satisfy our deliverables under the software development agreement. In addition, the MERS equity holders may exercise a put option to require us to purchase all of the remaining equity interests of MERS. Each of these terms is subject to certain price provisions. Because we do not have the ability to control MERS’ operations, we have recorded the purchase as an equity method investment and our ratable share of net income (loss) in MERS in future periods will be recorded in our consolidated statements of income as equity earnings of our unconsolidated subsidiaries, below operating income in other income (loss). On October 7, 2014, we acquired 100% of the outstanding common stock of SuperDerivatives, a leading provider of risk management analytics, financial market data and valuation services for $358 million in cash. The acquisition is intended to accelerate our multi-asset class clearing, risk management and market data strategy. On February 3, 2014, we acquired 100% of the outstanding common stock of Singapore Mercantile Exchange (which has been renamed ICE Futures Singapore). The acquisition included Singapore Mercantile Exchange Clearing Corporation (which has been renamed ICE Clear Singapore), a wholly-owned subsidiary of ICE Futures Singapore, which was the clearing house for all of its trades. ICE Futures Singapore operates commodity futures markets in Singapore. ICE Futures Singapore and ICE Clear Singapore retain licenses to operate as an approved exchange and an approved clearing house, regulated by the Monetary Authority of Singapore. These licenses provided us with exchange and clearing licenses in Asia. On December 2, 2014, we acquired 75% of the outstanding common stock of Holland Clearing House (which has been renamed ICE Clear Netherlands) to support our clearing strategy for financial products. ABN AMRO Clearing Bank N.V., or ABN AMRO, retained the remaining 25% minority interest in ICE Clear Netherlands. ICE Clear Netherlands is a continental European derivatives clearing house based in Amsterdam and is the primary clearing house for The Order Machine, or TOM, a multi-lateral trading facility for equity options. ICE Clear Netherlands is regulated and supervised in the Netherlands by the Authority for the Financial Markets and the Dutch Central Bank and is also European Market Infrastructure Regulation, or EMIR, authorized. ABN AMRO's 25% ownership has been recorded as “redeemable non-controlling interest” in the accompanying consolidated balance sheets.

Cash and Cash Equivalents [Abstract]
Short-Term and Long-Term Restricted Cash and Investments	Short-Term and Long-Term Restricted Cash and Investments We own ICE Futures Europe, which operates as a U.K. Recognized Investment Exchange. As a U.K. Recognized Investment Exchange, ICE Futures Europe is required by the Financial Conduct Authority in the U.K. to restrict the use of the equivalent of six months of operating expenditures, subject to certain deductions, in cash or cash equivalents or investments at all times. As of December 31, 2016 and 2015 , this amount for ICE Futures Europe was $77 million and $57 million , respectively. Such amounts are reflected as short-term restricted cash and investments in the accompanying consolidated balance sheets. The increase in the regulatory capital restricted cash at ICE Futures Europe as of December 31, 2016 was primarily due to additional costs incurred due to the growth of our trading businesses and the consequential additional regulatory capital buffers required by the Financial Conduct Authority. We own LIFFE Administration and Management, or Liffe, which also operated as a U.K. Recognized Investment Exchange. In November 2014, we completed the transition of Liffe’s contracts to ICE Futures Europe. We applied for a de-recognition order after the transition of Liffe's contracts to ICE Futures Europe but the regulatory capital for Liffe was required to be maintained until the de-recognition order was received. As of December 31, 2015, the regulatory capital for Liffe, which was held in pounds sterling, was $106 million ( £72 million ). The regulatory capital for Liffe was reflected as short-term restricted cash and investments in our consolidated balance sheet as of December 31, 2015. We received a de-recognition order for Liffe from the Financial Conduct Authority in August 2016, which resulted in the release of the Liffe regulatory capital, a decrease in our restricted cash and an increase in our cash and cash equivalents. As a U.K. Recognized Clearing House, ICE Clear Europe was required by the Bank of England to restrict the use of the equivalent of six months of operating expenditures, subject to certain deductions, in cash or cash equivalents or investments at all times. When EMIR became effective in September 2016, the Bank of England restricted cash capital requirements for ICE Clear Europe were superseded by the EMIR capital requirements. Restricted capital under EMIR is calculated to reflect an estimate of the capital required to wind down or restructure the activities of the clearing house, cover operational, legal and business risks and to reserve capital to meet credit, counterparty and market risks not covered by the members margin and guaranty funds. As such, it is calculated taking into account the operating expenditures, revenues and credit exposures associated with the assets and investments. As of December 31, 2016 and 2015 , the regulatory capital restricted cash for ICE Clear Europe was $352 million and $274 million , respectively, and were reflected as short-term restricted cash and investments in the accompanying consolidated balance sheets. Even though the EMIR capital requirements did not become effective until September 2016, we funded the regulatory capital restricted cash for ICE Clear Europe at $274 million as of December 31, 2015, which is what the capital requirements would have been for EMIR as of that date. The increase in the regulatory capital restricted cash at ICE Clear Europe as of December 31, 2016 was primarily due to additional costs incurred due to the growth of our clearing businesses and the consequential additional regulatory capital buffers required by the Bank of England. ICE Clear Europe, in addition to being regulated by the Bank of England, is also regulated by the Commodity Futures Trading Commission, or CFTC, as a U.S. Derivatives Clearing Organizations, or DCO. The regulatory capital available to ICE Clear Europe, as described above, exceeds the CFTC requirements. Our CFTC regulated U.S. Designated Contract Market, or DCM, ICE Futures U.S., our CFTC regulated U.S. DCOs, ICE Clear U.S. and ICE Clear Credit, our CFTC regulated U.S. Swap Data Repository, or SDR, ICE Trade Vault, and our U.S. Swap Execution Facility, or SEF, ICE Swap Trade, are required to maintain financial resources with a value at least equal to the amount that would cover certain operating costs for a one -year period, including maintaining cash or a committed line of credit, subject to certain deductions, to satisfy at least six months of such operating costs at all times. As of December 31, 2016 and 2015 , the financial resources reserved necessary to satisfy CFTC financial resource requirements for the DCM, U.S. DCOs, SDR and SEF were $192 million and $142 million , respectively. For our U.S. DCOs, ICE Clear U.S. and ICE Clear Credit, we have voluntarily chosen to reserve an additional $24 million as of December 31, 2016 (which is included in the $192 million above) consistent with the EMIR requirements to cover operational, legal and business risks and to reserve capital to meet credit, counterparty and market risks not covered by the member margin and guaranty funds. Our clearing houses require that each clearing member make deposits to a fund known as the guaranty fund. The amounts in the guaranty fund will serve to secure the obligations of a clearing member to our clearing houses and may be used to cover losses in excess of the margin and clearing firm accounts sustained by our clearing houses in the event of a default of a clearing member. As of December 31, 2016 and 2015 ; ICE Clear Europe has contributed $100 million of its own cash as part of its futures and options guaranty fund; ICE Clear Europe has contributed $50 million as part of its CDS guaranty fund; ICE Clear Credit has contributed $50 million as part of its CDS guaranty fund; ICE Clear U.S. has contributed $50 million as part of its futures and options guaranty fund; and ICE Clear Canada, ICE Clear Netherlands and ICE Clear Singapore have each also contributed a combined $3 million in cash to their respective guaranty funds. These cash contributions to the guaranty funds are reflected as long-term restricted cash in the accompanying consolidated balance sheets as of December 31, 2016 and 2015 . See Note 12 for additional information on the guaranty funds and our contributions of cash to our clearing houses guaranty funds. As of December 31, 2016 and 2015 , there is $44 million and $39 million , respectively, of additional combined cash reflected as short-term restricted cash and investment in the accompanying consolidated balance sheets related to other regulated entities and exchanges, including ICE Benchmark Administration, ICE Clear Netherlands, ICE Clear Canada, ICE Trade Vault U.K., ICE Endex and ICE Clear Singapore. The increase in the regulatory capital restricted cash as of December 31, 2016 was primarily due to additional costs incurred due to the growth of ICE Benchmark Administration's business and the consequential additional regulatory capital buffers required by the Financial Conduct Authority. As of December 31, 2016 and 2015 , there is $24 million and $50 million , respectively, of additional restricted cash, primarily related to escrow for recent acquisitions, including the SuperDerivatives acquisition that is reflected as short-term and long-term restricted cash and investments in the accompanying consolidated balance sheets. The decrease during 2016 was primarily due to the release of a portion of the cash held as escrow for the SuperDerivatives acquisition during the year ended December 31, 2016 .

Investments, Debt and Equity Securities [Abstract]
Short-Term and Long-Term Investments	Short-Term and Long-Term Investments As of December 31, 2016 , our short-term and long-term investments primarily consist of available-for-sale securities as follows (in millions): Cost Gross Unrealized Gains Gross Unrealized Losses Estimated Fair Value Cetip equity securities $ 324 $ 108 $ — $ 432 Mutual funds 23 — — 23 Total available-for-sale securities $ 347 $ 108 $ — $ 455 As of December 31, 2015 , our short-term and long-term investments primarily consist of available-for-sale securities as follows (in millions): Cost Gross Unrealized Gains Gross Unrealized Losses Estimated Fair Value Cetip equity securities $ 324 $ — $ (25 ) $ 299 Mutual funds 29 — — 29 Total available-for-sale securities $ 353 $ — $ (25 ) $ 328 We own 31.6 million shares, or 12% , of the common stock of Cetip. We account for our investment in Cetip as an available-for-sale investment and we classify it as a long-term investment in the accompanying consolidated balance sheets. The balance as of December 31, 2016 includes an unrealized gain of $108 million . Changes in the fair value of available-for-sale securities are reflected in accumulated other comprehensive income, and include the effects of both stock price and foreign currency translation fluctuations. The unrealized holding gains and losses are excluded from earnings and reported in other comprehensive income until realized. Realized gains and losses, and declines in value deemed to be other-than-temporary, are recognized in earnings. We recognized $19 million , $16 million , and $23 million in dividend income for the years ended December 31, 2016 , 2015 and 2014 , respectively, primarily related to our investment in Cetip, S.A., or Cetip, as other income. In April 2016, Cetip and BM&FBOVESPA in Brazil entered into a merger agreement. Consummation of the merger remains subject to approval by the regulatory bodies of the Central Bank of Brazil, the Securities and Exchange Commission of Brazil and Brazil’s Council for Economic Defense. The proposed merger values Cetip at R$47.61 per share based upon the December 31, 2016 BM&FBOVESPA closing stock price. Under the terms of the merger agreement, Cetip shareholders will receive a combination of cash (75%) and BM&FBOVESPA stock (25%). Given that a portion of the purchase price consists of BM&FBOVESPA stock, the merger agreement includes an adjustment mechanism that provides for a stock valuation based on the BM&FBOVESPA average trading price during the 30 trading days preceding the last required regulatory approval, with a minimum stock valuation of R$42.00 per share and a maximum stock valuation of R$48.51 per share. Equity and fixed income mutual funds are held for the purpose of providing future payments for the supplemental executive savings plan and the supplemental executive retirement plan (Note 14) are classified as available-for-sale securities.

The unamortized software and internally developed software balances were $207 million and $171 million as of December 31, 2016 and 2015 , respectively. The increase in the property and equipment as of December 31, 2016 is primarily due to building improvements at the corporate headquarters in Atlanta and New York during the year ended December 31, 2016.

The changes in other activity, net in the tables above primarily relate to adjustments to the fair value of the net tangible and identifiable intangible assets and liabilities relating to the acquisitions, with a corresponding adjustment to goodwill. The foreign currency translation adjustments in the tables above resulted from a portion of our goodwill and other intangible assets being held at our U.K., Continental European and Canadian subsidiaries, some of whose functional currencies are not the U.S. dollar. The foreign currency translation decrease for the year ended December 31, 2016 is primarily due to certain of our goodwill and intangible assets being recorded in pounds sterling, which decreased in value due to the weakening pound sterling exchange rate following the U.K. referendum vote in June 2016 to leave the European Union. In August 2016, we sold certain of Creditex’s U.S. voice brokerage operations to Tullett Prebon. During the third quarter of 2016, we discontinued Creditex’s U.K. voice brokerage operations. We continue to operate Creditex’s electronically traded markets and systems, post-trade connectivity platforms and intellectual property. We continued to monitor potential triggering events in our CDS trade execution business during 2016, including the impacts of divesting the brokerage business, changes in the business and regulatory climate in which the remaining business operates, the volatility in the capital markets, our recent operating performance and our current financial projections. Based on an analysis of these factors, it was determined that the carrying value of the Creditex customer relationship intangible asset was not fully recoverable and an impairment of the asset was recorded in September 2016 for $33 million based on a discounted cash flow calculation. The impairment was recorded as amortization expense within our Trading and Clearing segment in the accompanying consolidated statement of income for the year ended December 31, 2016 . As of December 31, 2016 , the remaining Creditex customer relationship intangible asset is $14 million and will continue to be amortized over the remaining useful life through August 2020. Other intangible assets and the related accumulated amortization consisted of the following as of December 31, 2016 and 2015 (in millions, except years): As of December 31, Useful Life (Years) 2016 2015 Customer relationships $ 4,063 $ 3,952 3 to 25 Technology 438 391 2.5 to 11 Trading products with finite lives 237 237 20 Russell licensing rights 184 184 10 Data/databases 145 76 4 to 10 Market data provider relationships 11 11 20 Non-compete agreements 38 37 1 to 5 Other 31 53 1 to 5 5,147 4,941 Less accumulated amortization (1,220 ) (703 ) Total finite-lived intangible assets, net 3,927 4,238 Exchange registrations, licenses and contracts with indefinite lives 6,083 6,086 Trade names and trademarks with indefinite lives 294 297 In-process research and development 108 129 Other 8 8 Total indefinite-lived intangible assets 6,493 6,520 Total other intangible assets, net $ 10,420 $ 10,758 For the years ended December 31, 2016 , 2015 and 2014 , amortization of other intangible assets was $323 million , $160 million and $151 million , respectively. Collectively, the remaining weighted average useful lives of the finite-lived intangible assets is 19.8 years as of December 31, 2016 .

The Credit Facility includes an option for us to propose an increase in the aggregate amount available for borrowing by up to $1.0 billion , subject to the consent of the lenders funding the increase and certain other conditions. On November 13, 2015, we utilized this option to increase the amount of the Credit Facility to $3.4 billion . The commitments under the Credit Facility will automatically reduce to $3.17 billion on April 3, 2019. No amounts were outstanding under the Credit Facility as of December 31, 2016 . Amounts borrowed under the Credit Facility may be prepaid at any time without premium or penalty. The Credit Facility provides for a $3.4 billion multi-currency revolving facility, with sub-limits for non-dollar borrowings and letters of credit and with a swing-line facility available on a same-day basis. Of the $3.4 billion that is currently available for borrowing under the Credit Facility, $1.6 billion is required to back-stop the amount outstanding under our Commercial Paper Program as of December 31, 2016 . The amount required to back-stop the amounts outstanding under the Commercial Paper Program will fluctuate as we increase or decrease our commercial paper borrowings. The remaining $1.8 billion available under the Credit Facility as of December 31, 2016 is available to us to use for working capital and general corporate purposes including, but not limited to, acting as a back-stop to future increases in the amounts outstanding under the Commercial Paper Program. Borrowings under the Credit Facility will bear interest on the principal amount outstanding at either (a) LIBOR plus an applicable margin rate or (b) a “base rate” plus an applicable margin rate; provided, however, that all loans denominated in a foreign currency will bear interest at LIBOR plus an applicable margin rate. The “base rate” equals the higher of (i) Wells Fargo’s prime rate, (ii) the federal funds rate plus 0.50% , or (iii) the one month LIBOR rate plus 1.00% . The applicable margin rate is based upon our public long term debt ratings and ranges from 0.875% to 1.50% on LIBOR borrowings and from 0.00% to 0.50% on base rate borrowings. The Credit Facility includes an unutilized revolving credit commitment fee that is equal to the unused maximum revolver amount, multiplied by an applicable commitment fee rate and is payable in arrears on a quarterly basis. The applicable commitment fee rate ranges from 0.08% to 0.20% and is determined based on our long term debt rating. As of December 31, 2016 , the applicable commitment fee rate was 0.125% based on our current long term debt ratings. The Credit Facility contains customary representations and warranties, covenants and events of default, including a leverage ratio, as well as limitations on liens on our assets, indebtedness of non-obligor subsidiaries, the sale of all or substantially all of our assets, and other matters. Commercial Paper Program We have entered into a U.S. dollar commercial paper program, or the Commercial Paper Program. Our Commercial Paper Program is currently backed by the borrowing capacity available under the Credit Facility, equal to the amount of the commercial paper that is issued and outstanding at any given point in time. The effective interest rate of commercial paper issuances does not materially differ from short term interest rates (such as USD LIBOR). The fluctuation of these rates due to market conditions may impact our interest expense. We used net proceeds from notes issued under the Commercial Paper Program during the year ended December 31, 2016 for the $431 million cash purchase price of the Securities Evaluations and Credit Market Analysis acquisitions and for general corporate purposes. We used net proceeds from notes issued under the Commercial Paper Program during the year ended December 31, 2015 to finance part of the cash portion of the purchase price of the Interactive Data acquisition and to pay related fees and expenses, to repurchase our common stock, and for general corporate purposes. We used net proceeds from notes issued under the Commercial Paper Program during the year ended December 31, 2014 to repay amounts outstanding under our prior credit facilities that were terminated in connection with us entering into the Credit Facility, to fund certain of our acquisitions, and to repurchase our common stock. We repaid a portion of the amounts outstanding under the Commercial Paper Program during the years ended December 31, 2016 , 2015 and 2014 with cash flows from operations and a portion of our unrestricted cash balances. We also repaid a portion of the amounts outstanding under the Commercial Paper Program during the year ended December 31, 2014 using a combination of the cash proceeds received from the IPO and sale of Euronext, and the sale of NYSE Technologies. Commercial paper notes of $1.6 billion with original maturities ranging from 3 to 68 days were outstanding as of December 31, 2016 under the Commercial Paper Program. As of December 31, 2016 , the weighted average interest rate on the $1.6 billion outstanding under the Commercial Paper Program was 0.74% per annum, with a weighted average maturity of 18 days. Commercial paper notes with original maturities ranging from 2 to 89 days were outstanding as of December 31, 2015 under the Commercial Paper Program. As of December 31, 2015 , the weighted average interest rate on the amounts outstanding under the Commercial Paper Program was 0.60% per annum, with a weighted average maturity of 19 days. 364 Day Facility On November 13, 2015, we entered into a $500 million 364 day senior unsecured revolving credit facility, or the 364 Day Facility, pursuant to a credit agreement with Wells Fargo, as administrative agent, Bank of America, N.A., as syndication agent, and the lenders signatory thereto. The amounts available under the 364 Day Facility were available for use by us for working capital and general corporate purposes but specifically excluding any use to back-stop amounts issued under the Commercial Paper Program. The 364 Day Credit Facility expired on November 13, 2016. Senior Notes In November 2015, we issued $2.5 billion in aggregate senior notes, including $1.25 billion principal amount of 2.75% senior unsecured fixed rate notes due November 2020, or the 2020 Senior Notes, and $1.25 billion principal amount of 3.75% senior unsecured fixed rate notes due November 2025, or the 2025 Senior Notes. We used the net proceeds from the 2020 Senior Notes and 2025 Senior Notes offering, together with $1.6 billion of borrowings under our Commercial Paper Program, to finance the $4.1 billion cash portion of the purchase price of the acquisition of Interactive Data. The 2020 Senior Notes and 2025 Senior Notes contain affirmative and negative covenants, including, but not limited to, certain redemption rights, limitations on liens and indebtedness, limitations on certain mergers, sales, dispositions and lease-back transactions. In October 2013, we issued $600 million principal amount of 2.50% senior unsecured fixed rate notes due October 2018, or the 2018 Senior Notes, and $800 million principal amount of 4.00% senior unsecured fixed rate notes due October 2023, or the 2023 Senior Notes. We used the net proceeds from the 2018 Senior Notes and 2023 Senior Notes offering to finance, together with cash on hand, the $2.7 billion cash portion of the purchase price of the acquisition of NYSE. The 2018 Senior Notes and 2023 Senior Notes contain affirmative and negative covenants, including, but not limited to, certain redemption rights, limitations on liens and indebtedness, limitations on certain mergers, sales, dispositions and lease-back transactions. NYSE Notes In connection with our acquisition of NYSE, one of our subsidiaries assumed the outstanding NYSE debt instruments, which included $850 million of 2.0% senior unsecured fixed rate notes due in October 2017, or the NYSE USD Notes, and €920 million ( $1.1 billion ) of 5.375% senior unsecured fixed rate notes due in June 2015, or the NYSE EUR Notes, and together with the NYSE USD Notes, the NYSE Notes. On June 30, 2015, we repaid the NYSE EUR Notes using cash that had been set aside in July 2014 from the proceeds of the Euronext IPO. The cash, in the amount of €969 million ($1.2 billion) had been placed in term deposits that matured on June 25, 2015. The cash was sufficient to settle the principal maturity of €920 million ($1.1 billion) and the final interest coupon of €49 million ($60 million). During the years ended December 31, 2015 and 2014 , the amortization of the increase in the fair value of the NYSE Notes that was recorded in connection with the NYSE acquisition purchase accounting was $23 million and $55 million , respectively. No further amortization expense was recorded after the repayment of the NYSE EUR Notes in June 2015. The terms of the bonds do not contain any financial covenants. The bonds may be redeemed by us or the bond holders under certain customary circumstances, including a change in control accompanied by a downgrade of the bonds below an investment grade rating. The terms of the bonds also provide for customary events of default and a negative pledge covenant. Debt Repayment Schedule As of December 31, 2016 , the outstanding debt repayment schedule is as follows (in millions): 2017 $ 2,494 2018 600 2019 — 2020 1,250 2021 — Thereafter 2,050 Principal amounts repayable 6,394 Debt issuance costs (23 ) Unamortized balance of fair value adjustments and discounts on bonds, net (7 ) Total debt outstanding $ 6,364 Debt Issuance Cost Presentation In April 2015, the FASB issued ASU 2015-03, which amends the existing guidance to require that debt issuance costs be presented in the balance sheet as a deduction from the carrying amount of the related debt liability instead of as a deferred asset (Note 2). We decided to early adopt ASU 2015-03 on a retrospective basis for the annual period ended December 31, 2015. As of December 31, 2016 and 2015, there are $23 million and $27 million , respectively, in debt issuance costs shown above as a deduction of the carrying value of the related debt liability or facilities. The $23 million in debt issuance costs as of December 31, 2016 will be amortized over a weighted average life of 6.3 years as interest expense. Interactive Data Debt Retirement At the date of the acquisition, Interactive Data had $2.6 billion of outstanding debt consisting of $1.9 billion under a credit facility, or the Interactive Data Credit Facility, and $700 million of senior notes, or the Interactive Data Senior Notes, all of which were repaid from the cash portion of the purchase price. In connection with the closing of the acquisition on December 14, 2015, the Interactive Data Credit Facility was repaid and terminated. On December 7, 2015, Interactive Data issued a notice of redemption with respect to the Interactive Data Senior Notes. On December 14, 2015, an amount sufficient to fully redeem the Interactive Data Senior Notes, plus accrued interest, was deposited with the Interactive Data Senior Notes trustee in trust, solely for the benefit of the holders of the Interactive Data Senior Notes. As a result, the indentures governing the Interactive Data Senior Notes were satisfied and discharged. Neither the cash deposited into the trust or the Interactive Data Senior Notes have been reflected on our consolidated balance sheet as of the acquisition date or December 31, 2015. The trustee paid the full amount held in the trust to holders of the Interactive Data Senior Notes at the redemption date on January 6, 2016.

Equity [Abstract]
Equity	Equity We currently sponsor employee and director stock option and restricted stock plans. Employee and director stock-based compensation expenses recognized for both stock options and restricted stock in the accompanying consolidated statements of income was $123 million , $111 million and $82 million for the years ended December 31, 2016 , 2015 and 2014 , respectively. The amount expensed for the years ended December 31, 2016 , 2015 and 2014 is net of $13 million , $11 million and $7 million , respectively, of stock-based compensation that was capitalized as software development costs. In March 2016, we early adopted ASU 2016-09, Stock Compensation (Topic 718) - Improvements to Employee Share-Based Payment Accounting , on a prospective basis (Note 2). Under the requirements of ASU 2016-09, we recognized $15 million in excess tax benefits for tax deductions in excess of cumulative compensation expenses for financial reporting purposes for the year ended December 31, 2016 through our consolidated statement of income. In addition, according to the guidance of ASU 2016-09, we made no adjustments for any excess tax benefits previously recorded in equity. For the years ended December 31, 2015 and 2014 , we recognized excess tax benefits of $19 million and $26 million , respectively, as an increase to the additional paid-in capital balance. As of December 31, 2016 , we had 14.3 million shares in total under various equity plans that are available for future issuance as stock option and restricted stock awards. Stock Split As discussed in Note 2, on November 3, 2016, a 5-for-1 split of our common stock was effected in the form of a four share stock dividend per share of common stock to shareholders of record as of the close of market on October 27, 2016. All share and earnings per share information has been retroactively adjusted to reflect the stock split. Stock Option Plans Stock options are granted at the discretion of the compensation committee of the board of directors. All stock options are granted at an exercise price equal to the fair value of the common stock on the date of grant. The grant date fair value is based on the closing stock price on the date of grant as well as certain other assumptions. The fair value of the stock options on the date of grant is recognized as expense ratably over the vesting period, net of estimated forfeitures. We may grant, under provisions of the plans, both incentive stock options and nonqualified stock options. The options generally vest over three years, but can vest at different intervals based on the compensation committee’s determination and the terms of the equity plans. Generally, options may be exercised up to ten years after the date of grant, but expire either 14 or 60 days after termination of employment unless an employee's employment agreement specifies otherwise. The shares of common stock issued under our stock option plans are made available from authorized and unissued common stock or treasury shares. The following is a summary of stock options for the years ended December 31, 2016 , 2015 and 2014 : Number of Options Weighted Average Outstanding at January 1, 2014 4,361,735 $ 19.58 Granted 771,010 41.37 Exercised (1,318,410 ) 10.37 Outstanding at December 31, 2014 3,814,335 27.21 Granted 882,335 41.59 Exercised (823,915 ) 20.40 Outstanding at December 31, 2015 3,872,755 31.93 Granted 751,615 50.01 Exercised (745,665 ) 28.73 Outstanding at December 31, 2016 3,878,705 36.05 Details of stock options outstanding as of December 31, 2016 are as follows: Number of Options Weighted Average Weighted Average Aggregate Vested or expected to vest 3,878,705 $ 36.05 6.6 $ 79 Exercisable 2,787,525 $ 31.61 5.8 $ 69 The total intrinsic value of stock options exercised during the years ended December 31, 2016 , 2015 and 2014 was $18 million , $22 million and $39 million , respectively. As of December 31, 2016 , there was $8 million in total unrecognized compensation costs related to stock options. These costs are expected to be recognized over a weighted average period of 1.7 years as the stock options vest. Of the options outstanding at December 31, 2016 , 2,787,525 were exercisable at a weighted-average exercise price of $31.61 . Of the options outstanding at December 31, 2015 , 2,699,865 were exercisable at a weighted-average exercise price of $27.87 . Of the options outstanding at December 31, 2014 , 2,809,220 were exercisable at a weighted-average exercise price of $23.33 . We use the Black-Scholes option pricing model for purposes of valuing stock option awards. During the years ended December 31, 2016 , 2015 and 2014 , we used the assumptions in the table below to compute the value of all options for shares of common stock granted to employees: Year Ended December 31, Assumptions 2016 2015 2014 Risk-free interest rate 1.51 % 1.08 % 1.23 % Expected life in years 5.0 5.0 5.0 Expected volatility 24 % 24 % 27 % Expected dividend yield 1.36 % 1.25 % 1.26 % Estimated fair value of options granted per share $ 9.88 $ 8.19 $ 9.05 The risk-free interest rate is based on the zero-coupon U.S. Treasury yield curve in effect at the time of grant. The expected life computation is derived from historical exercise patterns and anticipated future patterns. Expected volatilities are based on historical volatility of our stock. Restricted Stock Plans Restricted stock units are granted at the discretion of the compensation committee of the board of directors. We granted 3,251,017 , 3,457,590 and 2,801,900 time-based and performance-based restricted stock units during the years ended December 31, 2016 , 2015 and 2014 , respectively, including 2,325,985 , 1,871,785 and 1,929,485 time-based restricted stock units during the years ended December 31, 2016 , 2015 and 2014 , respectively. The grant date fair value of each award is based on the closing stock price at the date of grant. The fair value of the time-based restricted stock units on the date of grant is recognized as expense ratably over the vesting period, which is typically three years, net of forfeitures. Granted but unvested shares are generally forfeited upon termination of employment. When restricted stock is forfeited, compensation costs previously recognized for unvested shares are reversed. Until the shares vest and are issued, the participants have no voting or dividend rights and the shares may not be sold, assigned, transferred, pledged or otherwise encumbered. Unvested restricted stock earns dividend equivalents which are paid in cash on the vesting date. We recognize compensation costs, net of forfeitures, using an accelerated attribution method over the vesting period for awards with performance conditions. Compensation costs for such awards are recognized only if it is probable that the condition will be satisfied. If we initially determine that it is not probable that the performance condition will be satisfied and later determine that it is probable that the performance condition will be satisfied, or vice versa, the effect of the change in estimate is accounted for in the period of change by recording a cumulative catch-up adjustment to retroactively apply the new estimate. We recognize the remaining compensation costs over the remaining vesting period. Our compensation committee, pursuant to the terms of the equity plans and the authority delegated to it by our board of directors, can make equitable adjustments to the performance condition in recognition of unusual or non-recurring events. In January 2017, we reserved a maximum of 1,534,218 restricted shares for potential issuance as performance-based restricted shares to certain of our employees. The number of shares that will ultimately be granted under this award will be based on our actual financial performance as compared to financial performance targets set by our board of directors and compensation committee for the year ending December 31, 2017, as well as our total 2017 shareholder return as compared to that of the S&P 500 Index. The grant date of this award was January 18, 2017, which was the date when we and our employees reached a mutual understanding of award terms, and the service inception date as that is the date when the requisite service period began. The maximum compensation expense to be recognized under these performance-based restricted shares is $85 million if the maximum financial performance target is met and all 1,534,218 shares vest. The compensation expense to be recognized under these performance-based restricted shares will be $42 million if the target financial performance is met, which would result in 767,109 shares vesting. We will recognize expense on an accelerated basis over the three -year vesting period based on our quarterly assessment of the probable 2017 actual financial performance as compared to the 2017 financial performance targets. If the market condition is not achieved, the grant date fair value of the award will not be affected since the grant date fair value gave consideration to the probability of market condition achievement. In January 2016 , we reserved a maximum of 1,654,620 restricted shares for potential issuance as performance-based restricted shares for certain of our employees. These restricted shares were subject to a market condition that could have reduced the number of shares that were granted if our 2016 total shareholder return fell below that of the 2016 return of the S&P 500 Index and if we achieved above target financial performance level. Our total shareholder return for the year ended December 31, 2016 was higher than the 2016 return of the S&P 500 Index. Therefore, no share reduction was required. Based on our actual 2016 financial performance as compared to the 2016 financial performance level thresholds, 925,032 restricted shares were granted, which resulted in $45 million in compensation expenses that will be expensed over the three -year accelerated vesting period, including $26 million that was expensed during the year ended December 31, 2016 . The grant date fair values of the awards with a market condition were estimated based on our stock price on the grant date, the valuation of historical awards with market conditions, the relatively low likelihood that the market condition will affect the number of shares granted (as the market condition only affects shares granted in excess of certain financial performance targets), and our expectation of achieving the financial performance targets. The grant date fair value of the awards, when considering the impact of the market condition on fair value, was determined to not be materially different from our stock price on the respective grant dates. Restricted shares are used as an incentive to attract and retain qualified employees and to increase shareholder returns with actual performance linked to both short and long-term shareholder return. Our equity plans include a change in control provision that may accelerate vesting on both the time-based and performance-based restricted shares if the awards are not assumed by an acquirer in the case of a change in control. The following is a summary of the nonvested restricted shares under all plans discussed above for the years ended December 31, 2016 , 2015 and 2014 : Number of Weighted Average Nonvested at January 1, 2014 6,172,760 $ 29.40 Granted 2,801,900 40.98 Vested (3,276,460) 29.23 Forfeited (343,225) 32.57 Nonvested at December 31, 2014 5,354,975 35.36 Granted 3,457,590 42.09 Vested (2,182,805) 31.98 Forfeited (358,585) 33.90 Nonvested at December 31, 2015 6,271,175 39.99 Granted 3,251,017 50.06 Vested (2,640,640) 38.05 Forfeited (443,210) 45.51 Nonvested at December 31, 2016 6,438,342 45.33 Restricted stock shares granted in the table above include both time-based and performance-based grants. Performance-based shares have been presented to reflect the actual shares to be issued based on the achievement of past performance targets. Non-vested performance-based restricted shares granted are presented in the table above at the maximum number of restricted shares that would vest if the maximum performance targets are met. As of December 31, 2016 , there were $119 million in total unrecognized compensation costs related to the time-based restricted stock and the performance-based restricted stock. These costs are expected to be recognized over a weighted-average period of 1.2 years as the restricted stock vests. These unrecognized compensation costs assume that a target performance level will be met on the performance-based restricted shares granted in January 2017. During the years ended December 31, 2016 , 2015 and 2014 , the total fair value of restricted stock vested under all restricted stock plans was $130 million , $96 million and $138 million , respectively. Treasury Stock During the years ended December 31, 2016 , 2015 and 2014 , we received 1,074,162 shares, 979,295 shares and 1,203,380 shares, respectively, of common stock from certain of our employees related to tax withholdings made by us on our employee’s behalf for restricted stock and stock option exercises. We recorded the receipt of the shares as treasury stock. Treasury stock activity is presented in the accompanying consolidated statements of changes in equity, accumulated other comprehensive income (loss) and redeemable non-controlling interest. In connection with the record date for the 5-for-1 stock split on October 27, 2016, all shares of common stock held by us as treasury shares were canceled and extinguished. Therefore, as of the close of market on October 27, 2016, all 35,273,515 outstanding treasury stock shares were retired. In connection with the retirement, of the $1.5 billion value assigned to the treasury stock shares, $1.1 billion was allocated to additional paid-in capital and $370 million was allocated to retained earnings. The amount allocated to additional paid-in capital was determined based on the paid-in capital per share generated from the historical issuances of these treasury shares. Stock Repurchase Program During the years ended December 31, 2016 , 2015 and 2014 , we repurchased 902,920 shares, 14,343,845 shares and 16,157,420 shares, respectively, of our outstanding common stock at a cost of $50 million , $660 million and $645 million , respectively. These repurchases were completed under stock repurchase plans authorized by our board of directors. In connection with our acquisition of Interactive Data during the fourth quarter of 2015, we suspended our stock repurchase plan and it expired shortly thereafter. The timing and extent of future repurchases that are not made pursuant to a Rule 10b5-1 trading plan will be at our discretion and will depend upon many conditions. Our management and board of directors periodically review whether or not to be active in repurchasing our stock. In making a determination regarding any stock repurchases, we consider multiple factors. The factors may include: overall stock market conditions, our common stock price movements, the remaining amount authorized for repurchases by our board of directors, the potential impact of a stock repurchase program on our corporate debt ratings, our expected free cash flow and working capital needs, our current and future planned strategic growth initiatives, and other potential uses of our cash and capital resources. In August 2016, our board of directors approved an aggregate of $1.0 billion for future repurchases of our common stock with no fixed expiration date, subject to applicable laws and regulations. The shares repurchased are held in treasury stock. As of December 31, 2016, the remaining board authorization permits repurchases of up to $950 million of our common stock with no fixed expiration date. We expect funding for any share repurchases to come from our operating cash flow or borrowings under our debt facilities or commercial paper program. Repurchases may be made from time to time on the open market, through established plans, in privately-negotiated transactions or otherwise, in accordance with all applicable securities laws, rules and regulations. We have entered into a Rule 10b5-1 trading plan, as authorized by our board of directors, to govern some or all of the repurchases of our shares of common stock, and we began to repurchase shares in October 2016. We may discontinue the stock repurchases at any time and may amend or terminate the Rule 10b5-1 trading plan at any time. The approval of our board of directors for the share repurchases does not obligate us to acquire any particular amount of our common stock. In addition, our board of directors may increase or decrease the amount of capacity we have for repurchases from time to time. We repurchased shares of our common stock in the open market during the periods presented as follows: Number of Shares Average Repurchase Price Per Share Amount (in millions) 2016 Fourth quarter 902,920 $ 55.42 $ 50 Total open market common stock repurchases 902,920 $ 50 2015 Fourth quarter 1,163,975 $ 47.14 $ 56 Third quarter 4,455,675 46.27 206 Second quarter 4,362,695 46.44 202 First quarter 4,361,500 45.06 196 Total open market common stock repurchases 14,343,845 $ 660 Dividends The declaration of dividends is subject to the discretion of our board of directors, and may be affected by various factors, including our future earnings, financial condition, capital requirements, levels of indebtedness, credit ratings and other considerations our board of directors deem relevant. Our board of directors has adopted a quarterly dividend declaration policy providing that the declaration of any dividends will be determined quarterly by the board or audit committee of the board of directors taking into account such factors as our evolving business model, prevailing business conditions and our financial results and capital requirements, without a predetermined annual net income payout ratio. We declared and paid cash dividends per share during the periods presented as follows: Dividends Per Share Amount (in millions) 2016 Fourth quarter $ 0.17 $ 102 Third quarter 0.17 102 Second quarter 0.17 103 First quarter 0.17 102 Total cash dividends declared and paid 0.68 $ 409 2015 Fourth quarter $ 0.15 $ 90 Third quarter 0.15 83 Second quarter 0.15 85 First quarter 0.13 73 Total cash dividends declared and paid $ 0.58 $ 331

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Income from continuing operations before income taxes and the income tax provision consisted of the following for the years ended December 31, 2016 , 2015 and 2014 (in millions): Year Ended December 31, 2016 2015 2014 Income from continuing operations before income taxes Domestic $ 1,043 $ 824 $ 623 Foreign 986 829 784 $ 2,029 $ 1,653 $ 1,407 Income tax provision Current tax expense: Federal $ 258 $ 250 $ 151 State 5 46 61 Foreign 203 170 169 466 466 381 Deferred tax expense (benefit): Federal 65 (7 ) 39 State 76 (40 ) (20 ) Foreign (27 ) (61 ) 2 114 (108 ) 21 Total income tax expense $ 580 $ 358 $ 402 A reconciliation of the statutory U.S. federal income tax rate to our effective income tax rate for the years ended December 31, 2016 , 2015 and 2014 is as follows: Year Ended December 31, 2016 2015 2014 Statutory federal income tax rate 35 % 35 % 35 % State and local income taxes, net of federal benefit 3 2 3 Foreign tax rate differential (7 ) (7 ) (7 ) Benefit to deferred tax asset and liabilities for foreign tax law change (2 ) (4 ) — Uncertain tax positions — (3 ) 1 Other — (1 ) (3 ) Total provision for income taxes 29 % 22 % 29 % The effective tax rates for the years ended December 31, 2016 , 2015 and 2014 are lower than the federal statutory rate primarily due to the favorable foreign income tax rate differentials and favorable tax law changes, partially offset by state income taxes. Favorable foreign income tax rate differentials result primarily from lower income tax rates in the U.K. and various other lower tax jurisdictions as compared to the income tax rates in the U.S. During the fourth quarter of 2015, the U.K. reduced the corporate income tax rate from 20% to 19% effective April 1, 2017 and to 18% effective April 1, 2020. During the third quarter of 2016, the U.K. further reduced their corporate income tax rate from 18% to 17% effective April 1, 2020. The reduction in the future U.K. corporate income tax rates resulted in deferred tax benefits. The impact of the deferred tax benefit for the years ended December 31, 2016 and 2015 lowered the effective tax rates by 2% and 4%, respectively. The increase in the effective tax rate for the year ended December 31, 2016 , from the comparable period in 2015 , is primarily due to the tax impact of foreign versus U.S. based pre-tax income, lower deferred tax benefit associated with the future U.K. income tax rate reduction, and greater favorable settlements with various taxing authorities in 2015, partially offset by a tax benefit from the early adoption of ASU 2016-09 in 2016. The decrease in the effective tax rate for the year ended December 31, 2015, compared to the year ended December 31, 2014, is primarily due to the deferred tax benefit associated with future U.K. income tax rate reductions (representing $60 million of the $61 million deferred tax benefit in the income tax provision table above) along with certain favorable settlements with various taxing authorities. Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. We decided to early adopt ASU 2015-17 retrospectively and classified all deferred taxes and liabilities, along with any related valuation allowance, as non-current on the balance sheet as of December 31, 2015 (Note 2). The following table reflected the requirements under ASU 2015-17 and summarizes the significant components of our deferred tax liabilities and assets as of December 31, 2016 and 2015 (in millions): December 31, 2016 2015 Deferred tax assets: Deferred and stock-based compensation $ 166 $ 160 Pension 89 100 Liability reserve 52 58 Tax credits 64 59 Loss carryforward 127 259 Deferred revenue 38 29 Other 47 67 Total 583 732 Valuation allowance (122 ) (72 ) Total deferred tax assets, net of valuation allowance 461 660 Deferred tax liabilities: Property and equipment (113 ) (82 ) Acquired intangibles (3,302 ) (3,397 ) Total deferred tax liabilities (3,415 ) (3,479 ) Net deferred tax liabilities $ (2,954 ) $ (2,819 ) Reported as: Net non-current deferred tax assets $ 4 $ 18 Net non-current deferred tax liabilities (2,958 ) (2,837 ) Net deferred tax liabilities $ (2,954 ) $ (2,819 ) A reconciliation of the beginning and ending amount of deferred income tax valuation allowance is as follows for the years ended December 31, 2016 , 2015 and 2014 (in millions): Year Ended December 31, 2016 2015 2014 Beginning balance of deferred income tax valuation allowance $ 72 $ 75 $ 95 Increases charged to income tax expense 28 1 — Charges against goodwill 22 1 — Decreases — (5 ) (20 ) Ending balance of deferred income tax valuation allowance $ 122 $ 72 $ 75 We recognize valuation allowances on deferred tax assets if, based on the weight of the evidence, we believe that it is more likely than not that some or all of the deferred tax assets will not be realized. We recorded a valuation allowance for deferred tax assets of $122 million and $72 million as of December 31, 2016 and 2015 , respectively. Increases charged to income tax expense in the table above primarily relate to deferred tax assets on foreign net operating and capital losses that we do not expect to be realizable in future periods. Increases charged against goodwill in the table above primarily relate to deferred tax assets arising on the acquisition of a foreign branch that we do not expect to be realizable in future periods. Decreases in the table above for the years ended December 31, 2015 and 2014 relate to net operating loss carryforwards that we determined would be available to offset income in future periods. Our non-U.S. subsidiaries had $3.6 billion in cumulative undistributed earnings as of December 31, 2016 . This amount represents the post-income tax earnings under U.S. GAAP adjusted for previously taxed income. The earnings from our non-U.S. subsidiaries are considered to be indefinitely reinvested. Accordingly, no provision for U.S. federal and state income taxes has been made in the accompanying consolidated financial statements. Further, a determination of the unrecognized deferred tax liability is not practicable. Any future distribution by way of dividend of these non-U.S. earnings may subject us to both U.S. federal and state income taxes, as adjusted for non-U.S. tax credits, and withholding taxes payable to various non-U.S. countries. As of December 31, 2016 and 2015 , we have gross U.S. federal net operating loss carryforwards of $59 million and $340 million , respectively, and gross state and local net operating loss carryforwards of $293 million and $1.0 billion , respectively. The significant reduction of federal, state and local net operating losses results from their current year utilization. These carryforwards are available to offset future taxable income until they begin to expire in 2019. In addition, as of December 31, 2016 and 2015 , we have gross foreign net operating loss carryforwards of $116 million and $105 million , respectively. The majority of gross foreign net operating losses are not expected to be realizable in future periods and have related valuation allowances. A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows for the years ended December 31, 2016 , 2015 and 2014 (in millions): Year Ended December 31, 2016 2015 2014 Beginning balance of unrecognized tax benefits $ 107 $ 145 $ 228 Additions related to acquisitions 22 7 — Additions based on tax positions taken in current year 9 9 33 Additions based on tax positions taken in prior years — 34 1 Reductions related to divestitures (Euronext IPO) — — (104 ) Reductions based on tax positions taken in prior years (1 ) (51 ) (3 ) Reductions resulting from statute of limitation lapses (3 ) (12 ) (2 ) Reductions related to settlements with taxing authorities (22 ) (25 ) (8 ) Ending balance of unrecognized tax benefits $ 112 $ 107 $ 145 As of December 31, 2016 and 2015 , the balance of unrecognized tax benefits which would, if recognized, affect our effective tax rate was $76 million and $72 million , respectively. It is reasonably possible, as a result of settlements of ongoing audits or statute of limitations expirations, unrecognized tax benefits could increase as much as $9 million and decrease as much as $39 million within the next twelve months. Of the $112 million in unrecognized tax benefits as of December 31, 2016 , $84 million is recorded as other non-current liabilities and $28 million is recorded as other current liabilities in the accompanying consolidated balance sheet. We recognize interest accrued on income tax uncertainties and accrued penalties as a component of income tax expense. For the years ended December 31, 2016 , 2015 and 2014 , we recognized $1 million , $12 million and $4 million , respectively, of income tax expense for interest and penalties. Accrued interest and penalties were $35 million and $33 million as of December 31, 2016 and 2015 , respectively. Of the $35 million in accrued interest and penalties as of December 31, 2016 , $12 million is recorded as other non-current liabilities and $23 million is recorded as other current liabilities in the accompanying consolidated balance sheet. We or one of our subsidiaries files income tax returns in the U.S. federal jurisdiction and various state and foreign jurisdictions. The following table summarizes open tax years by major jurisdiction: Jurisdiction Open Tax Years U.S. Federal 2012 - 2016 U.S. States 2007 - 2016 U.K. 2015 - 2016 Netherlands 2011 - 2016 Although the outcome of tax audits is always uncertain, we believe that adequate amounts of tax, including interest and penalties, have been provided for any adjustments expected to result from open tax years.

Clearing Organizations

Clearing Organizations	12 Months Ended

Brokers and Dealers [Abstract]
Clearing Organizations	Clearing Organizations We operate regulated central counterparty clearing houses for the settlement and clearance of derivative contracts. The clearing houses include ICE Clear Europe, ICE Clear Credit, ICE Clear U.S., ICE Clear Canada, ICE Clear Netherlands and ICE Clear Singapore (referred to herein collectively as the “ICE Clearing Houses”). • ICE Clear Europe performs the clearing and settlement for all futures and options contracts traded through ICE Futures Europe and ICE Endex, for energy futures and options contracts trading through ICE Futures U.S., and for CDS contracts submitted for clearing in Europe. • ICE Clear Credit performs the clearing and settlement for CDS contracts submitted for clearing in North America. • ICE Clear U.S. performs the clearing and settlement of agricultural, metals, currencies and financial futures and options contracts traded through ICE Futures U.S. • ICE Clear Canada performs the clearing and settlement for all futures and options contracts traded through ICE Futures Canada. • ICE Clear Netherlands offers clearing for The Order Machine, a multi-lateral trading facility for equity options. • ICE Clear Singapore performs the clearing and settlement for all futures and options contracts traded through ICE Futures Singapore. Each of the ICE Clearing Houses requires all clearing members to maintain cash on deposit or pledge certain assets, which may include government obligations, non-government obligations or gold to guarantee performance of the clearing members’ open positions. Such amounts in total are known as “original margin”. The ICE Clearing Houses may make intraday original margin calls in circumstances where market conditions require additional protection. The daily profits and losses from and to the ICE Clearing Houses due to the marking-to-market of open contracts is known as “variation margin”. The ICE Clearing Houses mark all outstanding contracts to market, and therefore pay and collect variation margin, at least once daily, and in some cases multiple times throughout the day. Marking-to-market allows the ICE Clearing Houses to identify any clearing members that may be unable to satisfy the financial obligations resulting from changes in the prices of their open contracts before those financial obligations become exceptionally large and jeopardize the ability of the ICE Clearing Houses to ensure financial performance of clearing members’ open positions. Each of the ICE Clearing Houses requires that each clearing member make deposits into a fund known as a “guaranty fund”, which is maintained by the relevant ICE Clearing House. These amounts serve to secure the obligations of a clearing member to the ICE Clearing House to which it has made the guaranty fund deposit and may be used to cover losses sustained by the respective ICE Clearing House in the event of a default of a clearing member. Each of the ICE Clearing Houses has equal and offsetting claims to and from their respective clearing members on opposite sides of each cleared contract. This arrangement allows the ICE Clearing Houses to serve as the central financial counterparty on every cleared contract. Each ICE Clearing House bears financial counterparty credit risk in the event that market movements create conditions that lead to its clearing members failing to meet their financial obligations to that ICE Clearing House. Accordingly, the ICE Clearing Houses account for this central counterparty guarantee as a performance guarantee. Given that each contract is margined and marked-to-market or settled at least once daily for each clearing member, the ICE Clearing Houses’ maximum estimated exposure for this guarantee, excluding the effects of original and variation margin requirements and mandatory deposits to the applicable guaranty fund by clearing members, is $84.7 billion as of December 31, 2016 , which represents the maximum estimated value by the ICE Clearing Houses of a hypothetical one day movement in pricing of the underlying unsettled contracts. This amount is based on calculations determined using proprietary risk management software that simulates gains and losses based on historical market prices, volatility and other factors present at that point in time for those particular unsettled contracts. Future actual market price volatility could result in the exposure being significantly different than the amount estimated by the ICE Clearing Houses. The net notional value of unsettled contracts was $2.5 trillion as of December 31, 2016 . We performed calculations to determine the fair value of our counterparty performance guarantee taking into consideration factors such as daily settlement of contracts, margining requirements, other elements of our risk management program, historical evidence of default payments, and estimated probability of potential default payouts by the ICE Clearing Houses. Based on these analyses, the estimated counterparty performance guaranty liability was determined to be nominal and no liability was recorded as of December 31, 2016 and 2015 . The ICE Clearing Houses seek to reduce their exposure through a risk management program that includes initial and ongoing financial standards for clearing member admission and continued membership, original and variation margin requirements, and mandatory deposits to the guaranty fund. The amounts that the clearing members are required to maintain in the original margin and guaranty fund accounts are determined by standardized parameters established by the risk management departments and reviewed by the risk committees and the boards of directors of each of the ICE Clearing Houses and may fluctuate over time. As of December 31, 2016 and 2015 , the ICE Clearing Houses have received or have been pledged $95.7 billion and $87.2 billion , respectively, in cash and non-cash collateral in original margin and guaranty fund deposits to cover price movements of underlying contracts for both periods. The ICE Clearing Houses also have powers of assessment that provide the ability to collect additional funds from their clearing members to cover a defaulting member’s remaining obligations up to the limits established under the respective rules of each ICE Clearing House. Should a particular clearing member fail to deposit original margin, or fail to make a variation margin payment, when and as required, the relevant ICE Clearing House may liquidate or hedge the clearing member’s open positions and use the clearing member’s original margin and guaranty fund deposits to make up any amount owed. In the event that those deposits are not sufficient to pay the amount owed in full, the ICE Clearing Houses may utilize the respective guaranty fund deposits of their respective clearing members on a pro-rata basis for that purpose. We have contributed $150 million , $50 million and $50 million in cash to the ICE Clear Europe, ICE Clear Credit and ICE Clear U.S. guaranty funds, respectively, as of December 31, 2016 , and such amounts are at risk and could be used in the event of a clearing member default where the amount of the defaulting clearing member’s original margin and guaranty fund deposits are insufficient. ICE Clear Canada, ICE Clear Netherlands and ICE Clear Singapore have each also contributed a combined $3 million in cash to their respective guaranty funds. The $253 million combined contributions to the guaranty funds as of December 31, 2016 and 2015 are included in long-term restricted cash in the accompanying consolidated balance sheets (Note 4). For ICE Clear Europe, if a futures and options clearing member’s deposits are depleted and a default occurs, then a $100 million contribution made by us to the ICE Clear Europe guaranty fund would be utilized after the available funds of the defaulting clearing member but before all other amounts within the guaranty fund. The $100 million is solely available in the event of an ICE Clear Europe futures and options clearing member default. The $50 million contribution to the ICE Clear U.S. guaranty fund and the $50 million contribution to the ICE Clear Credit guaranty fund would be utilized after the available funds of the defaulting clearing member but before all other amounts within the guaranty fund. We have contributed $50 million to the ICE Clear Europe CDS guaranty fund. The first $33 million contributed to the ICE Clear Europe CDS guaranty fund will be utilized after the available funds of the defaulting CDS clearing member but before all other amounts within the guaranty fund. The additional $17 million contributed to the ICE Clear Europe CDS guaranty fund will be utilized pro-rata along with other non-defaulting CDS clearing members’ deposits in the guaranty fund. Subject to regulatory approval, ICE Clear Europe plans to move the total $50 million contribution to the CDS guaranty fund to be utilized after the available funds of the defaulting clearing member but before all other amounts within the guaranty fund. As of December 31, 2016 , our cash margin deposits and guaranty fund are as follows for the ICE Clearing Houses (in millions): ICE Clear Europe ICE Clear ICE Clear U.S. Other ICE Clearing Houses Total Original margin $ 27,046 $ 16,833 $ 6,184 $ 107 $ 50,170 Guaranty fund 2,444 2,135 316 85 4,980 Total $ 29,490 $ 18,968 $ 6,500 $ 192 $ 55,150 As of December 31, 2015 , our cash margin deposits and guaranty fund are as follows for the ICE Clearing Houses (in millions): ICE Clear Europe ICE Clear ICE Clear U.S. Other ICE Clearing Houses Total Original margin $ 28,454 $ 13,750 $ 3,882 $ 159 $ 46,245 Guaranty fund 2,589 2,011 311 13 4,924 Total $ 31,043 $ 15,761 $ 4,193 $ 172 $ 51,169 We have recorded these cash deposits in the accompanying consolidated balance sheets as current assets with corresponding current liabilities to the clearing members of the relevant ICE Clearing House. All cash and securities are available only to meet the financial obligations of that clearing member to the relevant ICE Clearing House. ICE Clear Europe, ICE Clear Credit, ICE Clear U.S., ICE Clear Canada, ICE Clear Netherlands and ICE Clear Singapore are separate legal entities and are not subject to the liabilities of the other ICE Clearing Houses or the obligations of the members of the other ICE Clearing Houses. The amount of these cash deposits may fluctuate due to the types of margin collateral choices available to clearing members and the change in the amount of deposits required. As a result, these assets and corresponding liabilities may vary significantly over time. Of the cash held by the ICE Clearing Houses, as of December 31, 2016 , $44.0 billion is secured in reverse repurchase agreements with primarily overnight maturities or direct investment in government securities. ICE Clear Credit, as a systemically important financial market utility by the Financial Stability Oversight Council, held $7.3 billion of its U.S. dollar cash in the guaranty fund and in original margin in the cash account at the Federal Reserve Bank of Chicago as of December 31, 2016 (Note 2). The remaining cash deposits at the ICE Clearing Houses are held in demand deposit accounts at large, highly rated financial institutions and directly in U.S. Treasury securities with original maturities of less than 12 months. The carrying value of these securities approximates their fair value due to the short-term nature of the instruments and repurchase agreements. Of the $29.5 billion of ICE Clear Europe cash deposits as of December 31, 2016 , which are primarily held in U.S. dollars, euros and pounds sterling, $24.5 billion relates to futures and options products and $5.0 billion relates to cleared OTC European CDS instruments. ICE Clear Europe offers a separate clearing platform, risk model and risk pool for futures and options products that is distinct from those associated with cleared OTC European CDS instruments. In addition to the cash deposits for original margin and the guaranty fund, the ICE Clearing Houses have also received other assets from clearing members, which include government obligations, and may include other non-cash collateral such as certain agency and corporate debt or gold to mitigate credit risk. These assets are not reflected in the accompanying consolidated balance sheets as the risks and rewards of these assets remain with the clearing members unless the ICE Clearing Houses have sold or re-pledged the assets or in the event of a clearing member default, where the clearing member is no longer entitled to redeem the assets. Any income, gain or loss accrues to the clearing member. For certain non-cash deposits, the ICE Clearing Houses may impose discount or “haircut” rates to ensure adequate collateral levels to account for fluctuations in the market value of these deposits. As of December 31, 2016 and 2015 , the assets pledged by the clearing members as original margin and guaranty fund deposits for each of the ICE Clearing Houses are detailed below (in millions): As of December 31, 2016 As of December 31, 2015 ICE Clear Europe ICE Clear ICE Clear U.S. Other ICE Clearing Houses ICE Clear Europe ICE Clear ICE Clear U.S. Other ICE Clearing Houses Original margin: Government securities at face value $ 22,961 $ 6,013 $ 10,542 $ 37 $ 21,690 $ 4,989 $ 8,161 $ 97 Other — — — 368 — — — 381 Total $ 22,961 $ 6,013 $ 10,542 $ 405 $ 21,690 $ 4,989 $ 8,161 $ 478 Guaranty fund: Government securities at face value $ 217 $ 178 $ 147 $ 40 $ 267 $ 229 $ 158 $ 61

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Leases We lease office space, equipment facilities and certain computer equipment under lease agreements that expire at various dates through 2028. Our leases typically contain terms which may include renewal options, rent escalations, rent holidays and leasehold improvement incentives. We had no capital leases as of December 31, 2016 and 2015 . Rental expense under these leases, included in the accompanying consolidated statements of income in rent and occupancy and technology and communication expenses, totaled $65 million , $53 million and $76 million for the years ended December 31, 2016 , 2015 , and 2014 , respectively. As of December 31, 2016 , future minimum lease payments under these non-cancelable operating agreements are as follows (in millions): 2017 $ 85 2018 82 2019 66 2020 60 2021 53 Thereafter 266 Total $ 612 Redeemable Non-controlling Interest As part of the ICE Endex purchase agreement, Gasunie has a put option to sell to us, and we have a call option to purchase from Gasunie, Gasunie’s entire 21% remaining ownership in ICE Endex at fair market value provided that the fair value falls between a stated cap and floor. Both the call and put option became exercisable on March 26, 2015 and they both expire on March 26, 2018. As part of the ICE Clear Netherlands acquisition (Note 3), ABN AMRO has a put option to sell to us, and we have a call option to purchase from ABN AMRO, ABN AMRO’s entire remaining 25% ownership in ICE Clear Netherlands at fair market value subject to a stated floor. Both the call and put option become exercisable after the third anniversary of the date of closing of the acquisition which was December 2, 2014. Since the likelihood of us acquiring both of the non-controlling interests in the future is probable, we have recorded the full redemption fair value of $36 million and $35 million as of December 31, 2016 and 2015 , respectively, relating to ICE Endex and ICE Clear Netherlands as mezzanine equity and classified the related balance as “redeemable non-controlling interest” in the accompanying consolidated balance sheets and the proportionate share of profits was recorded as net income from continuing operations attributable to non-controlling interest in the consolidated statements of income. Changes in the redemption value of the non-controlling interest are recorded to the redeemable non-controlling interest balance in full as they occur. Prior to the our acquisition of NYSE, NYSE completed the sale of a significant equity interest in NYSE Amex Options, one of our two U.S. options exchanges, to seven external investors. Under the terms of the sale, the external investors had the option to require us to repurchase a portion of the equity interest on an annual basis. Since the likelihood of us acquiring the non-controlling interest was probable, the full redemption fair value had been recorded as mezzanine equity and the related balance as “redeemable non-controlling interest” in the consolidated balance sheets and the proportionate share of profits was recorded as net income from continuing operations attributable to non-controlling interest in the consolidated statements of income. In July 2014 we repurchased 16% of the interest held by the seven external investors for $129 million in cash, and in June 2015 we repurchased the remaining 16% of the interest for $128 million in cash. Effective from July 1, 2015, all of the profits from NYSE Amex Options are retained by us as we now own 100% of NYSE Amex Options. Legal Proceedings We are subject to legal proceedings and claims that arise in the course of our business. Typically, we do not believe that the resolution of ordinary course matters, including the matters described below, will have a material adverse effect on our consolidated financial condition, results of operations, or liquidity. It is possible, however, that future results of operations for any particular quarterly or annual period could be materially and adversely affected by any developments relating to the legal proceedings and claims. The matters described below all relate to our operation of NYSE. A range of possible losses related to the cases below cannot be reasonably estimated at this time, except as otherwise disclosed below. In April 2014, New York Stock Exchange LLC and NYSE Arca, Inc., two of our subsidiaries, were among more than 40 financial institutions and exchanges named as defendants in four purported class action lawsuits filed in the U.S. District Court for the Southern District of New York, or the Southern District, by the City of Providence, Rhode Island, and other plaintiffs. In subsequent consolidated amended complaints, the plaintiffs asserted claims against the exchange defendants and Barclays PLC, or Barclays, a subsidiary of which operates an alternative trading system known as Barclays LX, on behalf of a class of “all public investors” who bought or sold stock from April 18, 2009 to the present on the U.S.-based equity exchanges operated by the exchange defendants or on Barclays LX. In August 2015, the court issued an opinion and order granting the defendants’ motions to dismiss and dismissing the second amended complaint in its entirety with prejudice. The court held that the plaintiffs had failed to sufficiently state a claim against the defendants under Sections 10(b) and 6(b) of the Exchange Act, and additionally that some of the claims against the exchanges were barred by the doctrine of self-regulatory organization immunity. In September 2015, the plaintiffs filed a notice of appeal of the dismissal of the lawsuit to the U.S. Court of Appeals for the Second Circuit, or the Second Circuit. The appeal was briefed and argued during 2016, and the parties are awaiting a decision. In May 2014, three purported class action lawsuits were filed (and later amended) in the Southern District by Harold Lanier against the securities exchanges that are participants in each of the three national market system data distribution plans - the Consolidated Tape Association/Consolidated Quotation Plan, the Nasdaq UTP Plan, and the Options Price Reporting Authority, or the Plans, - which are established under the Exchange Act and regulated by the SEC. New York Stock Exchange LLC, NYSE Arca, Inc. and NYSE MKT LLC, which are our subsidiaries, were among the defendants named in one or more of the suits, in which Lanier claimed to sue on behalf of himself and all other similarly situated subscribers to the market data disseminated by the Plans. Lanier’s allegations included that the exchange participants in the Plans breached agreements with subscribers by disseminating market data in a discriminatory manner in that other “preferred” customers allegedly received their data faster than the proposed class. In September 2014, the defendants moved to dismiss the amended complaints, and in April 2015, the court issued an opinion and order granting the motion and dismissing the three lawsuits with prejudice. In September 2016, the Second Circuit entered an order affirming the dismissal of the lawsuits. In November 2016, the Second Circuit denied a petition filed by Lanier, relating only to the lawsuit involving the Options Price Reporting Authority plan, seeking a rehearing by the panel of judges that decided the appeal or, in the alternative, for review by the full Second Circuit. In December 2015, our subsidiaries New York Stock Exchange LLC and NYSE MKT LLC received an inquiry from the Enforcement staff of the New York regional office (the “Staff”) of the SEC regarding a July 8, 2015 outage on the NYSE markets, during which trading was suspended for approximately 3.5 hours in all symbols. The Staff’s investigation proceeded throughout 2016. On December 29, 2016, NYSE received a Wells Notice stating that the Staff have made a preliminary determination to recommend that the SEC file an enforcement action in connection with how NYSE responded on July 8, 2015 to the circumstances leading into the suspension of trading that day. NYSE disputes the appropriateness of the proposed charges, believes there are substantial defenses, and has made a written submission to the Staff in response to the Wells Notice setting forth such points. If the Staff determines to maintain its recommendation contained in the Wells Notice, the Commissioners of the SEC will need to determine whether to authorize the filing of an enforcement action. 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 involving us or one of our subsidiaries, 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 continuously review our positions as these matters progress.

Compensation and Retirement Disclosure [Abstract]
Pension and Other Benefit Programs	Pension and Other Benefit Programs Defined Benefit Pension Plan We have a pension plan covering certain of our U.S. operations. The benefit accrual for the pension plan is frozen. Retirement benefits are derived from a formula, which is based on length of service and compensation. Based on this calculation, we may contribute to our pension plan to the extent such contributions may be deducted for income tax purposes. During the years ended December 31, 2016 , 2015 and 2014, we contributed $10 million , $10 million and $51 million , respectively, to our pension plan. Our practice is to fund our frozen defined benefit pension plan each year at the level above the minimum required contribution but within tax deductible limits. Based on actuarial projections, we estimate that a contribution of $10 million during the year ended December 31, 2017 will allow us to meet our funding goal. However, the actual contribution is contingent on the actual plan performance relative to assumptions. During the year ended December 31, 2014 , as part of certain plan amendments, lump sum payments were offered to certain terminated vested participants as part of a de-risking strategy in the pension plan. The offer was made to 2,725 participants, of whom 935 , or 34% , elected to receive a lump sum. The total amount paid to this group was $55 million and when combined with other lump sum payments made during the year, it exceeded the total interest cost and service cost for the year. We recognized a loss of $4 million for the year ended December 31, 2014 in connection with these plan settlements, which is included in acquisition-related transaction and integration cost in our consolidated statement of income. We base our investment policy and objectives on a review of the actuarial and funding characteristics of the retirement plan, the demographic profile of plan participants, and our business and financial characteristics. Capital market risk/return opportunities and tradeoffs also are considered as part of the determination. The primary investment objective of our plan is to achieve a long-term rate of return that meets the actuarial funding requirements of the plan and maintain an asset level sufficient to meet all benefit obligations of the plan. The target allocations for the U.S. plan assets are 65 percent equity securities and 35 percent U.S. fixed income securities. Equity securities primarily include investments in large-cap and small-cap companies primarily located in the U.S., which include corporate bonds of companies from diversified industries and U.S. treasuries. Based on the valuation techniques described in Note 15, the fair values of our pension plan assets as of December 31, 2016 , by asset category, are as follows (in millions): Fair Value Measurements Asset Category Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Total Cash $ 21 $ — $ — $ 21 Equity securities: U.S. large-cap — 247 — 247 U.S. small-cap — 68 — 68 International — 134 — 134 Fixed income securities 106 102 3 211 Total $ 127 $ 551 $ 3 $ 681 The fair values of our pension plan assets as of December 31, 2015 , by asset category, are as follows (in millions): Fair Value Measurements Asset Category Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Total Cash $ 11 $ — $ — $ 11 Equity securities: U.S. large-cap — 244 — 244 U.S. small-cap — 69 — 69 International — 128 — 128 Fixed income securities 128 83 3 214 Total $ 139 $ 524 $ 3 $ 666 The measurement dates for the pension plan are December 31, 2016 and 2015 .

Gains/losses on plan assets are amortized over a four year period and accumulate in other comprehensive income. We recognize deferred gains and losses in future net income based on a “corridor” approach, where the corridor is equal to 10% of the greater of the benefit obligation or the market-related value of plan assets at the beginning of the year. The following table shows the projected payments for the pension plan based on actuarial assumptions (in millions): 2017 $ 50 2018 50 2019 49 2020 49 2021 49 Next 5 years 248 Supplemental Executive Retirement Plan We have a U.S. nonqualified supplemental executive retirement plan, or SERP, which provides supplemental retirement benefits for certain employees. The future benefit accrual of the SERP plan is frozen. To provide for the future payments of these benefits, we have purchased insurance on the lives of certain of the participants through company-owned policies. As of December 31, 2016 and 2015 , the cash surrender value of such policies was $53 million and $51 million , respectively, and is included in other non-current assets in the accompanying consolidated balance sheets. The following table provides a summary of the changes in the SERP benefit obligations (in millions): As of December 31, 2016 2015 Change in benefit obligation: Benefit obligation at beginning of year $ 61 $ 73 Interest cost 1 2 Actuarial (gain) loss 1 (3 ) Benefits paid (9 ) (11 ) Benefit obligation at year end $ 54 $ 61 Funded status $ (54 ) $ (61 ) Amounts recognized in the accompanying consolidated balance sheets: Other current liabilities $ (8 ) $ (9 ) Accrued employee benefits (46 ) (52 ) SERP plan expense in the accompanying consolidated statements of income was $1 million , $2 million and $3 million for the years ended December 31, 2016 , 2015 and 2014 , respectively, and primarily consisted of interest cost. The following table shows the projected payments for the SERP plan based on the actuarial assumptions (in millions): Projected SERP Plan Payments 2017 $ 8 2018 7 2019 5 2020 5 2021 5 Next 5 years 17 Pension and SERP Plans Assumptions The weighted-average assumptions used to develop the actuarial present value of the projected benefit obligation and net periodic pension/SERP costs for years ended December 31, 2016 , 2015 and 2014 are set forth below: Year Ended December 31, 2016 2015 2014 Weighted-average discount rate for determining benefit obligations (pension/SERP plans) 3.9%/3.4% 4.0%/3.4% 3.8%/3.2% Weighted-average discount rate for determining interest costs (pension/SERP plans) 3.3%/2.5% 3.8%/3.2% 4.6%/3.8% Expected long-term rate of return on plan assets (pension/SERP plans) 6.5%/N/A 6.5%/N/A 6.5%/N/A Rate of compensation increase N/A N/A N/A The assumed discount rate reflects the market rates for high-quality corporate bonds currently available. The discount rate was determined by considering the average of pension yield curves constructed on a large population of high quality corporate bonds. The resulting discount rates reflect the matching of plan liability cash flows to yield curves. To develop the expected long-term rate of return on assets assumption, we considered the historical returns and the future expectations for returns for each asset class as well as the target asset allocation of the pension portfolio. In the fourth quarter of 2015, we changed the method we used to estimate the interest component of net periodic benefit cost for pension and other postretirement benefits. We made this change to provide a more precise measurement of interest cost by improving the correlation between projected benefit cash flows to the corresponding spot yield curve rates. This change does not affect the measurement of our total benefit obligations. Historically, we estimated the interest cost component utilizing a single weighted-average discount rate derived from the yield curve used to measure the benefit obligation at the beginning of the period. We have elected to utilize a full yield curve approach in the estimation of these components by applying the specific spot rates along the yield curve used in the determination of the benefit obligation to the relevant projected cash flows. We accounted for this change as a change in accounting estimate that is inseparable from a change in accounting principle and accordingly have accounted for it prospectively. Post-retirement Benefit Plans Our defined benefit plans provide certain health care and life insurance benefits for certain eligible retired NYSE U.S. employees. These post-retirement benefit plans, which may be modified in accordance with their terms, are fully frozen. The net periodic post-retirement benefit costs were $7 million , $8 million and $9 million for the years ended December 31, 2016 , 2015 and 2014 , respectively. The defined benefit plans are unfunded and we currently do not expect to fund the post-retirement benefit plans. The weighted-average discount rate for determining the benefit obligation as of December 31, 2016 and 2015 is 3.9% and 4.1% , respectively. The weighted-average discount rate for determining the interest cost as of December 31, 2016 and 2015 is 3.3% and 3.8% , respectively. The following table shows the actuarial determined benefit obligation, interest costs, employee contributions, actuarial (gain) loss, benefits paid during the periods and the accrued employee benefits (in millions): As of December 31, 2016 2015 Benefit obligation at the end of year $ 200 $ 224 Interest cost 7 8 Actuarial gain (20 ) (12 ) Employee contributions 3 3 Benefits paid (14 ) (14 ) Amounts recognized in the accompanying consolidated balance sheets: Other current liabilities $ (11 ) $ (12 ) Accrued employee benefits $ (189 ) $ (212 ) The following table shows the payments projected for our post-retirement benefit plans (net of expected Medicare subsidy receipts of $11 million in aggregate over the next ten fiscal years) based on actuarial assumptions (in millions): 2017 $ 12 2018 12 2019 12 2020 12 2021 12 Next 5 years 63 For measurement purposes, we assumed an 8.1% annual rate of increase in the per capita cost of covered health care benefits in 2016 which will decrease on a graduated basis to 4.5% in the year 2038 and thereafter. The following table shows the effect of a one-percentage-point increase and decrease in assumed health care cost trend rates (in millions): Assumed Health Care Cost Trend Rate 1% Increase 1% Decrease Effect of post-retirement benefit obligation $ 24 $ (20 ) Effect on total of service and interest cost components 1 (1 ) Accumulated Other Comprehensive Loss The accumulated other comprehensive loss, after tax, as of December 31, 2016 , consisted of the following amounts that have not yet been recognized in net periodic benefit cost (in millions): Pension Plans SERP Plans Post-retirement Benefit Plans Total Unrecognized net actuarial losses, after tax $ 103 $ 3 $ 3 $ 109 The amount of prior actuarial loss included in accumulated other comprehensive income related to the pension, SERP and postretirement plans as of December 31, 2016 , which are expected to be recognized in net periodic benefit cost in the coming year, is estimated to be (in millions): Pension Plans SERP Plans Post-retirement Benefit Plans Total Loss recognition $ 2 $ — $ — $ 2 Other Benefit Plans and Defined Contribution Plans Our U.S. employees are eligible to participate in 401(k) and profit sharing plans and our non-U.S employees are eligible to participate in defined contribution pension plans. Total contributions under the 401(k), profit sharing and defined contribution pension plans were $31 million , $21 million and $29 million for the years ended December 31, 2016 , 2015 and 2014 , respectively. No discretionary or profit sharing contributions were made during the years ended December 31, 2016 , 2015 or 2014 .

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Our financial instruments consist primarily of cash and cash equivalents, short-term and long-term restricted cash and investments, short-term and long-term investments, customer accounts receivable, margin deposits and guaranty funds, cost and equity method investments, short-term and long-term debt and certain other short-term assets and liabilities. The fair value of our financial instruments are measured based on a three-level hierarchy: • Level 1 inputs — quoted prices for identical assets or liabilities in active markets. • Level 2 inputs — observable inputs other than Level 1 inputs such as quoted prices for similar assets and liabilities in active markets or inputs other than quoted prices that are directly observable. • Level 3 inputs — unobservable inputs supported by little or no market activity and that are significant to the fair value of the assets or liabilities. We use Level 1 inputs to determine fair value. The Level 1 assets consist of U.S. Treasury securities, equity and other securities listed in active markets, and investments in publicly traded mutual funds held for the purpose of providing future payments of the SERP and SESP plans. Financial assets and liabilities recorded in the accompanying consolidated balance sheets as of December 31, 2016 and 2015 are classified in their entirety based on the lowest level of input that is significant to the asset or liability’s fair value measurement. Financial instruments measured at fair value on a recurring basis as of December 31, 2016 are as follows (in millions): Level 1 Level 2 Level 3 Total Assets at fair value: Long-term investment in equity securities $ 432 $ — $ — $ 432 U.S. Treasury securities 500 — — 500 Mutual Funds 23 — — 23 Total assets at fair value $ 955 $ — $ — $ 955 Financial instruments measured at fair value on a recurring basis as of December 31, 2015 are as follows (in millions): Level 1 Level 2 Level 3 Total Assets at fair value: Long-term investment in equity securities $ 299 $ — $ — $ 299 U.S. Treasury securities 449 — — 449 Mutual Funds 29 — — 29 Total assets at fair value $ 777 $ — $ — $ 777 As of December 31, 2016 , the fair value of our $1.24 billion 2020 Senior Notes was $1.27 billion , the fair value of our $1.24 billion 2025 Senior Notes was $1.29 billion , the fair value of our $851 million NYSE USD Notes was $855 million , the fair value of our $790 million 2023 Senior notes was $836 million , and the fair value of our $598 million 2018 Senior Notes was $607 million . The fair values of these fixed rate notes were estimated using quoted market prices for these instruments. 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 December 31, 2016 . All other financial instruments are determined to approximate carrying value due to the short period of time to their maturities. The long-term investment in equity securities as of December 31, 2016 and 2015 represents our investment in Cetip, recorded at its fair value using its quoted market price (Note 5). The mutual funds represent equity and fixed income mutual funds held for the purpose of providing future payments to the SERP and SESP (Note 14). As of December 31, 2016 , we were holding $500 million in U.S. Treasury securities, all of which had original maturities of less than one year from the date of purchase. Of these securities, $350 million were recorded as short-term restricted cash and investments and $150 million were recorded as long-term restricted cash and investments in the accompanying consolidated balance sheet as of December 31, 2016 . As of December 31, 2015 , we were holding $449 million in U.S. Treasury securities, all of which had original maturities of less than one year from the date of purchase. Of these securities, $25 million were recorded as cash and cash equivalents, $274 million were recorded as short-term restricted cash and investments and $150 million were recorded as long-term restricted cash and investments in the accompanying consolidated balance sheet as of December 31, 2015 . We account for the U.S. Treasury securities held using the available-for-sale method. All of the U.S. Treasury securities recorded as cash and cash equivalents have original maturities of less than 90 days. We did not use Level 2 and 3 inputs to determine the fair value of assets or liabilities measured at fair value on a recurring basis as of December 31, 2016 and 2015 . We measure certain assets, such as intangible assets and cost and equity method investments, at fair value on a non-recurring basis. These assets are recognized at fair value if they are deemed to be impaired. As of December 31, 2016 and 2015 , none of these assets were required to be recorded at fair value since none of these assets were deemed impaired.

Discontinued Operations and Disposal Groups [Abstract]
Discontinued Operations	Discontinued Operations On June 24, 2014, we sold an aggregate 65.8 million shares of common stock of our wholly-owned subsidiary Euronext N.V., or Euronext, representing 94% of Euronext's outstanding shares, and on December 9, 2014, we sold our remaining 6% , or 4.2 million shares of Euronext common stock. We no longer hold any shares of Euronext stock and the sale of Euronext generated an aggregate €1.5 billion ( $2.1 billion ) of net cash proceeds for us. The net cash proceeds received included cash of $220 million distributed from Euronext as part of the separation of Euronext. On July 23, 2014, we sold Wombat, a unit of NYSE Technologies, to SR Labs. On September 19, 2014 we sold NYFIX and Metabit, the remaining businesses of NYSE Technologies, to ULLINK. These agreements completed our previously announced intention to divest non-core NYSE Technologies assets. We used the cash proceeds from the sale of Euronext and NYSE Technologies to repay debt (Note 9). Due to the sale of Euronext and the sales of the three companies comprising NYSE Technologies, we included the financial results of these entities in discontinued operations in the accompanying consolidated financial statements. There was no gain or loss recognized on the sale of Euronext or on the sale of the NYSE Technologies companies, as any differences in the carrying value of these net assets was adjusted in the NYSE purchase price allocation. The results below include external advisory costs and professional services costs related to the sales of Euronext and NYSE Technologies of $51 million for the year ended December 31, 2014 , which have been included below with acquisition-related transaction and integration costs, from discontinued operations. The results below also include deal-related compensation and severance costs related to the sales of Euronext and NYSE Technologies of $42 million for the year ended December 31, 2014 , which have also been included with acquisition-related transaction and integration costs below from discontinued operations.

Earnings Per Share [Abstract]
Earnings Per Common Share	Earnings Per Common Share The following is a reconciliation of the numerators and denominators of the basic and diluted earnings per common share computations for the years ended December 31, 2016 , 2015 and 2014 (in millions, except per share amounts): Year Ended December 31, 2016 2015 2014 Income from continuing operations $ 1,449 $ 1,295 $ 1,005 Net income from continuing operations attributable to non-controlling interest (27 ) (21 ) (35 ) Net income from continuing operations attributable to ICE 1,422 1,274 970 Net income from discontinued operations attributable to ICE — — 11 Net income attributable to ICE $ 1,422 $ 1,274 $ 981 Basic earnings per share attributable to ICE common shareholders: Continuing operations $ 2.39 $ 2.29 $ 1.70 Discontinued operations — — 0.02 Basic earnings per share $ 2.39 $ 2.29 $ 1.72 Basic weighted average common shares outstanding 595 556 570 Diluted earnings per share attributable to ICE common shareholders: Continuing operations $ 2.37 $ 2.28 $ 1.69 Discontinued operations — — 0.02 Diluted earnings per share $ 2.37 $ 2.28 $ 1.71 Diluted weighted average common shares outstanding 599 559 573 Basic weighted average common shares outstanding 595 556 570 Effect of dilutive securities - stock options and restricted stock 4 3 3 Diluted weighted average common shares outstanding 599 559 573 Basic earnings per common share is calculated using the weighted average common shares outstanding during the periods. The weighted average common shares outstanding increased for the year ended December 31, 2016 , over the prior year period, primarily due to stock issued for the Interactive Data and Trayport acquisitions, partially offset by stock repurchases. The weighted average common shares outstanding decreased for the year ended December 31, 2015 , from the prior year period, primarily due to stock repurchases during 2015, partially offset by the stock issued for the Interactive Data and Trayport acquisitions at the end of 2015. We issued 32.3 million shares of our common stock to Interactive Data stockholders and 12.6 million shares of our common stock to Trayport stockholders, weighted to show these additional shares outstanding for periods after the respective acquisition dates (Note 3). Common equivalent shares from stock options and restricted stock awards, using the treasury stock method, are included in the diluted per share calculations unless the effect of their inclusion would be antidilutive. During the years ended December 31, 2016 , 2015 and 2014, 724,918 , 836,405 and 773,436 outstanding stock options, respectively, were not included in the computation of diluted earnings per common share, because to do so would have had an antidilutive effect. As of December 31, 2016 and 2015 , there were 110,265 and 227,330 restricted stock units, respectively, that were vested but have not been issued that are included in the computation of basic and diluted earnings per share. Certain figures in the table above may not recalculate due to rounding.

Summary of Significant Accoun29

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2016
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying consolidated financial statements are presented in accordance with U.S. generally accepted accounting principles, or U.S. GAAP. The consolidated financial statements include our wholly-owned and controlled subsidiaries. All intercompany balances and transactions between our wholly-owned and controlled subsidiaries have been eliminated in consolidation. As discussed in Note 3, we completed several acquisitions during the years ended December 31, 2016 , 2015 and 2014 and have included the financial results of these companies in the consolidated financial statements effective from the respective acquisition dates. As discussed in Note 16, we completed the initial public offering, or IPO, of our wholly-owned subsidiary Euronext N.V., or Euronext, in June 2014 and completed the sales of Wombat in July 2014 and NYFIX and Metabit in September 2014, and have included the financial results of these companies in discontinued operations in the consolidated financial statements.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires our management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements. Estimates also affect the reported amounts of revenues and expenses during the reporting period. Actual amounts could differ from those estimates.
Comprehensive Income	Comprehensive Income Other comprehensive income includes changes in unrealized gains and losses on financial instruments classified as available-for-sale, changes in fair value of net investment hedges, foreign currency translation adjustments, income from equity method investments, and amortization of the difference in the projected benefit obligation and the accumulated benefit obligation associated with benefit plan liabilities, net of tax.
Noncontrolling Interest	Non-controlling Interest For those consolidated subsidiaries in which our ownership is less than 100% and for which we have control over the assets and liabilities and the management of the entity, the outside stockholders’ interests are shown as non-controlling interests. For instances where outside stockholders’ hold an option to require us to repurchase the outside stockholders’ interest, these interests are shown as redeemable non-controlling interests.
Segment And Geographic Information	Segment and Geographic Information
Cash and Cash Equivalents	Cash and Cash Equivalents We consider all short-term, highly liquid investments with original maturities at the purchase date of three months or less to be cash equivalents.
Short-Term and Long-Term Restricted Cash and Investments	Short-Term and Long-Term Restricted Cash and Investments We classify all cash and cash equivalents and investments that are not available for immediate or general business use by us as restricted in the accompanying consolidated balance sheets (Note 4). The restricted cash would include cash set aside due to regulatory requirements, earmarked for specific purposes, or restricted by specific agreements
Short-Term and Long-Term Investments	Short-Term and Long-Term Investments We periodically invest a portion of our cash in excess of short-term operating needs in term deposits and investment-grade marketable debt securities, including government or government sponsored agencies and corporate debt securities (Note 5). These investments are classified as available-for-sale in accordance with U.S. GAAP. We do not have any investments classified as held-to-maturity or trading. Additionally, we classify equity and fixed income mutual funds, held for the purpose of providing future payments for the supplemental executive savings plan and a component of the supplemental executive retirement plan, as available-for-sale securities. Available-for-sale investments are carried at their fair value using primarily quoted prices in active markets for identical securities, with unrealized gains and losses, net of deferred income taxes, reported as a component of accumulated other comprehensive income. Realized gains and losses, and declines in value deemed to be other-than-temporary on available-for-sale investments, are recognized currently in earnings. The cost of securities sold is based on the specific identification method. Investments that we intend to hold for more than one year are classified as long-term investments in the accompanying consolidated balance sheets.
Cost and Equity Method Investments	Cost and Equity Method Investments We use the cost method to account for a non-marketable equity investment in an entity that we do not control and for which we do not have the ability to exercise significant influence over an entity’s operating and financial policies. When we do not have a controlling financial interest in an entity but exercise significant influence over the entity's operating and financial policies, such investment is accounted for using the equity method. We account for our investments in MERSCORP Holdings, Inc., or MERS, and Options Clearing Corporation, or OCC, as equity method investments. We recognized $25 million , $6 million and $25 million in equity income related to these investments during the years ended December 31, 2016 , 2015 and 2014 , respectively, as other income.
Margin Deposits and Guaranty Funds	Margin Deposits and Guaranty Funds Original margin, variation margin and guaranty funds held by our clearing houses for clearing members may be in the form of cash, government obligations, certain agency and corporate debt or gold (Note 12). Cash original margin, variation margin and guaranty fund deposits are reflected in the accompanying consolidated balance sheets as current assets and current liabilities. The amount of margin deposits on hand will fluctuate over time as a result of, among other things, the extent of open positions held at any point in time by market participants in contracts and the margin rates then in effect for such contracts. Non-cash original margin and guaranty fund deposits are not reflected in the accompanying consolidated balance sheets as the risks and rewards of these assets remain with the clearing members unless the clearing houses have sold or re-pledged the assets or in the event of a clearing member default, where the clearing member is no longer entitled to redeem the assets.
Property and Equipment	Property and Equipment Property and equipment is recorded at cost, reduced by accumulated depreciation (Note 6). Depreciation and amortization expense related to property and equipment is computed using the straight-line method based on estimated useful lives of the assets, or in the case of leasehold improvements, the shorter of the initial lease term or the estimated useful life of the improvement. We review the remaining estimated useful lives of our property and equipment at each balance sheet date and will make adjustments to the estimated remaining useful lives whenever events or changes in circumstances indicate that the remaining useful lives have changed. Gains on disposals of property and equipment are included in other income and losses on disposals of property and equipment are included in depreciation expense. Maintenance and repair costs are expensed as incurred.
Allowance for Doubtful Accounts	Allowance for Doubtful Accounts The allowance for doubtful accounts is maintained at a level that we believe to be sufficient to absorb probable losses in our accounts receivable portfolio. The allowance is based on several factors, including a continuous assessment of the collectability of each account. In circumstances where a specific customer's inability to meet its financial obligations is known, we record a specific provision for bad debts against amounts due to reduce the receivable to the amount we reasonably believe will be collected. Accounts receivable are written off against the allowance for doubtful accounts when collection efforts cease. A reconciliation of the beginning and ending amount of allowance for doubtful accounts is as follows for the years ended December 31, 2016 , 2015 and 2014 (in millions): Year Ended December 31, 2016 2015 2014 Beginning balance of allowance for doubtful accounts $ 2 $ 1 $ 1 Bad debt expense 5 2 1 Charge-offs — (1 ) (1 ) Ending balance of allowance for doubtful accounts $ 7 $ 2 $ 1 Bad debt expense in the table above is based on our historical collection experiences and our assessment of the collectability of specific accounts. Charge-offs in the table above represent the write-off of uncollectible receivables, net of recoveries. These lines also include the impact of foreign currency translation adjustments.
Software Development Costs	Software Development Costs We capitalize costs, both internal and external direct and incremental costs, related to software developed or obtained for internal use in accordance with U.S. GAAP . Software development costs incurred during the preliminary or maintenance project stages are expensed as incurred, while costs incurred during the application development stage are capitalized and are amortized using the straight-line method over the useful life of the software, not to exceed three years (except for Interactive Data's and NYSE's new platforms, which have eight year useful lives). Amortization of these capitalized costs begins only when the software becomes ready for its intended use. General and administrative costs related to developing or obtaining such software are expensed as incurred.
Accrued Employee Benefits	Accrued Employee Benefits We have a defined benefit pension plan and other postretirement benefit plans, or collectively the “benefit plans”, covering certain of our U.S. operations. The benefit accrual for the pension plan is frozen. We recognize the funded status of the benefit plans in the consolidated balance sheets, measure the fair value of plan assets and benefit obligations as of the date of our fiscal year-end, and provide additional disclosures in the footnotes to the consolidated financial statements (Note 14). Benefit plan costs and liabilities are dependent on assumptions used in calculating such amounts. These assumptions include discount rates, health care cost trend rates, benefits earned, interest cost, expected return on assets, mortality rates and other factors. Actual results that differ from the assumptions are accumulated and amortized over future periods and, therefore, generally affect recognized expense and the recorded obligation in future periods. We immediately recognize in the consolidated statements of income certain of these unrecognized amounts when triggering events occur, such as when a settlement of pension obligations in excess of total interest and service costs occurs. While we believe that the assumptions used are appropriate, differences in actual experience or changes in assumptions may affect our pension and other post-retirement obligations and future expense recognized.
Goodwill and Indefinite-Lived Intangible Assets	Goodwill and Indefinite-Lived Intangible Assets Goodwill represents the excess of the purchase price of our acquisitions over the fair value of identifiable net assets acquired, including other identified intangible assets (Note 7). We recognize specifically identifiable intangibles when a specific right or contract is acquired. Goodwill has been allocated to reporting units for purposes of impairment testing based on the portion of synergy, cost savings and other expected future cash flows expected to benefit the reporting units at the time of the acquisition. We test our goodwill for impairment at the reporting unit level. The reporting units identified for our goodwill testing are the futures, data and listings, cash and CDS reporting units. Goodwill impairment testing is performed annually in the fiscal fourth quarter or more frequently if conditions exist that indicate that the asset may be impaired. We also evaluate indefinite-lived intangible assets for impairment annually in our fiscal fourth quarter or more frequently if conditions exist that indicate that the asset may be impaired. Such evaluation includes either applying the optional qualitative screen to determine if it is not more likely than not that the fair value of the asset continues to exceed its carrying value or determining the fair value of the asset and comparing the fair value of the asset to its carrying value. If the fair value of the indefinite-lived intangible asset is less than its carrying value, an impairment loss is recognized in an amount equal to the difference. For both goodwill and indefinite lived impairment testing, we have the option to first perform a qualitative assessment to determine whether it is more likely than not that the fair value of a reporting unit or indefinite lived intangible asset is less than its carrying amount. If we conclude that this is the case, we must perform additional testing of the asset or reporting unit. Otherwise, no further testing is necessary. We did not record an impairment charge related to goodwill or indefinite lived intangible assets during the years ended December 31, 2016 , 2015 or 2014 .
Impairment of Long-Lived Assets and Finite-Lived Intangible Assets	Impairment of Long-Lived Assets and Finite-Lived Intangible Assets We review our property and equipment and finite-lived intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount may not be fully recoverable. To analyze recoverability, we project undiscounted net future cash flows over the remaining life of such assets. If these projected cash flows are less than the carrying amount, an impairment indicator would exist. The impairment loss is measured based upon the difference between the carrying amount and the fair value of the assets. Finite-lived intangible assets are generally amortized on a straight-line basis or using an accelerated method over the lesser of their contractual or estimated useful lives.
Derivatives and Hedging Activity	Derivatives and Hedging Activity We may use derivative instruments to limit exposure to changes in foreign currency exchange rates. All derivatives are required to be recorded at fair value in the accompanying consolidated balance sheets. Changes in the fair value of such derivative financial instruments are recognized in net income as they are not designated as hedges under U.S. GAAP. From time to time, we may hedge the foreign currency translation of certain net investments by designating all or a portion of certain financial liabilities denominated in the same currency in accordance with U.S. GAAP. We entered into foreign currency hedging transactions during years ended December 31, 2016 , 2015 and 2014 as economic hedges to help mitigate a portion of our foreign exchange risk exposure. During the year ended December 31, 2014, we recognized a loss of $21 million as a component of income from discontinued operations upon discontinuance of the net investment hedge in connection with the IPO of Euronext.
Intellectual Property	Intellectual Property All costs related to internally developed patents and trademarks are expensed as incurred. All costs related to purchased patents, trademarks and internet domain names are recorded as other intangible assets and are amortized on a straight-line basis over their estimated useful lives. All costs related to licensed patents are capitalized and amortized on a straight-line basis over the term of the license.
Income Taxes	Income Taxes We recognize income taxes under the liability method. We recognize a current tax liability or tax asset for the estimated taxes payable or refundable on tax returns for the current year. We recognize deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the financial statement carrying amounts and the tax bases of assets and liabilities. We establish valuation allowances if we believe that it is more likely than not that some or all of our deferred tax assets will not be realized. Deferred tax assets and liabilities are measured using current enacted tax rates in effect. We do not recognize a tax benefit unless we conclude that it is more likely than not that the benefit will be sustained on audit by the taxing authority based solely on the technical merits of the associated tax position. If the recognition threshold is met, we recognize a tax benefit measured at the largest amount of the tax benefit that, in our judgment, is greater than 50 percent likely to be realized. We recognize accrued interest and penalties related to uncertain tax positions as a component of income tax expense. We are subject to tax in numerous domestic and foreign jurisdictions primarily based on our operations in these jurisdictions. Significant judgment is required in assessing the future tax consequences of events that have been recognized in our financial statements or tax returns. Fluctuations in the actual outcome of these future tax consequences could have a material impact on our financial position or results of operations.
Revenue Recognition	Revenue Recognition We recognize revenue when persuasive evidence of an arrangement exists, delivery has occurred, the sale price is fixed or determinable and collectability is reasonably assured. Our revenues primarily consist of transaction and clearing fee revenues for transactions executed and/or cleared through our global electronic derivatives trading and clearing platforms and cash equities trading and revenues related to our data services fees and listing fees. We also evaluate all contracts in order to determine appropriate gross versus net revenue reporting. Derivatives trading and clearing revenues are recognized over the period in which the services are provided, which is typically the date the transactions are executed or are cleared, except for a portion of clearing revenues related to cleared contracts which have an ongoing clearing obligation that extends beyond the execution date. The transaction and clearing fee revenues are determined on the basis of the transaction and clearing fee charged for each contract traded on the exchanges. Derivatives transaction and clearing fees are recorded net of rebates of $674 million , $563 million and $466 million for the years ended December 31, 2016 , 2015 and 2014 , respectively. We offer rebates in certain of our markets primarily to support market liquidity and trading volume by providing qualified participants in those markets a discount to the applicable commission rate. Such rebates are calculated based on volumes traded. The increase in the rebates is due primarily to an increase in the number of participants in the rebate programs offered on various contracts, an increase in our traded volume and an increase in the number of rebate programs. Cash trading fee revenues are paid by organizations based on their trading activity. Fees are assessed on a per share basis for trading in equity securities. The fees are applicable to all transactions that take place on any of our equity trading venues, and the fees vary based on the size and type of trade that is consummated and trading venue. The equity trading venues earn transaction fees for customer orders of equity securities matched internally, as well as for customer orders routed to other exchanges. Cash trading fees are recognized as earned, which is generally upon execution of the trade. Cash trading fees are recorded gross of liquidity rebates and routing charges. Liquidity payments made to cash and options trading customers and routing charges made to other exchanges are included in transaction-based expenses in the consolidated statements of income. Listings revenues consist of original listing fees paid by issuers to list the initial securities on the various cash markets, other listing fees related to other corporate actions (including stock splits, sales of additional securities and merger and acquisitions), annual listing fees paid by companies whose financial instruments are listed on the cash markets, and other services provided to our listed companies and other companies. Original listing fees are assessed primarily based on the number of shares that the issuer initially lists. Original listing fees are recognized as revenue on a straight-line basis over the estimated service periods ranging from 5 to 9 years. Other corporate action listing fees are recognized as revenue on a straight-line basis over the estimated service periods ranging from 3 to 6 years. The service periods are determined separately for each of our listing venues (Note 8). Annual listing fees are billed at the beginning of the year and are recognized on a pro rata basis over the calendar year. Data services revenues in our derivatives markets primarily include terminal and license fees received from data vendors in exchange for the provision of real-time futures price information and market data access fees. Market data fees are charged to data vendors on a monthly basis based on the number and type of terminals they have carrying futures data. Each data vendor also pays an annual license fee, which is deferred and recognized as revenue ratably over the period of the annual license. Data services revenues also include market data access fees charged to customers that trade on the electronic platform. The market data access amount for each company is based on the number of users at each company trading on the electronic platform. Monthly trading commissions are recognized as transaction and clearing fee revenues. Any customer's market data access fees in excess of that customer's commissions on trading activity are recognized as market data access revenues. We collect market data revenues from our cash equity and options consortium-based data products and, to a lesser extent, for New York Stock Exchange proprietary data products. Consortium-based data fees are determined by securities industry plans. Consortium-based data revenues that coordinated market data distribution generates (net of administration costs) are distributed to participating markets on the basis of the Regulation NMS formula. We collect annual license fees from vendors for the right to distribute market data to third parties and a service fee from vendors for direct connection to market data. These fees are recognized as revenue as services are rendered. We also charge customers for accessing our data services through Secure Financial Transaction Infrastructure, or SFTI, and colocation services. SFTI is a physical network infrastructure that connects our markets and other major market centers with market participants and allows those participants to receive data feeds. Data analytics includes a number of products such as forward curves, index and valuation services. Revenue for subscription based contracts is recognized ratably over the life of the contract and revenue for usage based contracts is recognized in the month that the products/services are provided. Certain of our businesses collect fees for installation/set-up services which, if deemed a separate deliverable with standalone value, are recognized upon delivery as long as the remaining criteria for recognition of revenue have been achieved. Revenue for installation/set-up services, that do not meet the criteria for separation, is recognized ratably either over the contractual term or the expected client relationship life. Revenue for professional services is recognized as the services are provided. Revenue for hardware is recognized when installation is completed and the related services go-live. Some contracts include multiple elements for which we determine whether the various elements meet the applicable criteria to be accounted for as separate elements and makes estimates regarding the relative fair values. Revenue for elements that cannot be separated is recognized once the revenue recognition criteria for the entire arrangement have been met or over the period that our obligation to perform is fulfilled. Consideration for elements that are deemed separable is allocated to the separate elements at the inception of the arrangement on the basis of their relative selling price and recognized based on meeting authoritative criteria to do so. Other revenues primarily consist of various fees for services provided to our customers, including interest income on certain clearing margin deposits, regulatory penalties and fines, fees for use of our facilities, regulatory fees charged to member organizations of our U.S. securities exchanges, designated market maker service fees, exchange membership fees and agricultural grading and certification fees. These fees are recognized as revenue as services are rendered.
Activity Assessment and Section 31 Fees	Activity Assessment Fees and Section 31 Fees We pay the Securities and Exchange Commission, or SEC, fees pursuant to Section 31 of the Securities Exchange Act of 1934 for transactions executed on our U.S. equities and options exchanges. These Section 31 fees are designed to recover the costs to the government for supervising and regulating the securities markets and securities professionals. We (or the OCC on our behalf), in turn, collect activity assessment fees, which are included in transaction and clearing fees in the accompanying consolidated statements of income, from member organizations clearing or settling trades on the U.S. equities and options exchanges and recognize these amounts as revenue when invoiced. Fees received are included in cash at the time of receipt and, as required by law, the amount due to the SEC is remitted semi-annually and recorded as an accrued liability until paid. The activity assessment fees are designed so that they are equal to the Section 31 fees paid by us to the SEC. As a result, Section 31 fees do not have an impact on our net income.
Stock-Based Compensation	Stock-Based Compensation We currently sponsor employee and director stock option and restricted stock plans (Note 10). U.S. GAAP requires the measurement and recognition of compensation expenses for all share-based payment awards made to employees and directors, including employee stock options and restricted stock, based on estimated fair values. U.S. GAAP requires companies to estimate the fair value of stock option awards on the date of grant using an option-pricing model. The value of the portion of the award that is ultimately expected to vest is recognized as stock-based compensation expense over the requisite service period in our consolidated financial statements. We use the Black-Scholes option pricing model for purposes of valuing stock option awards. Our determination of fair value of stock option awards on the date of grant using the Black-Scholes option pricing model is affected by our stock price as well as assumptions regarding a number of subjective variables. These variables include interest rates, our expected dividend yield, our expected share price volatility over the term of the awards and actual and projected employee stock option exercise behavior.
Treasury Stock	Treasury Stock We record treasury stock activities under the cost method whereby the cost of the acquired stock is recorded as treasury stock (Note 10). We retired all of our outstanding treasury shares effective October 27, 2016, the record date of the stock split mentioned above. Our accounting policy upon the formal retirement of treasury stock is to deduct the par value from common stock and to reflect any excess of cost over par value as a deduction from additional paid-in capital (to the extent created by previous issuances of the shares) and retained earnings.
Credit Risk and Significant Customers	Credit Risk and Significant Customers Our clearing houses have credit risk for maintaining certain of the clearing member cash deposits at various financial institutions (Note 12). Cash deposit accounts are established at larger money center banks and structured to restrict the rights of offset or liens by the banks. Our clearing houses monitor the cash deposits and mitigate credit risk by keeping such deposits in several financial institutions, ensuring that its overall credit risk exposure to any individual financial institution remains within acceptable concentration limits, and by ensuring that the financial institutions have high investment grade ratings. We also limit our risk of loss by holding the majority of the cash deposits in high quality short-term sovereign debt reverse repurchase agreements with several different counterparty banks or direct investments in short-term high quality sovereign and supranational debt issues. While we seek to achieve a reasonable rate of return which may generate interest income for our clearing members, we are primarily concerned with preservation of capital and managing the risks associated with these deposits. As the clearing houses may pass on interest revenues, minus costs, to the members, this could include negative or reduced yield due to market conditions. When engaging in reverse repurchase agreements, our clearing houses take delivery of the underlying securities in custody accounts under clearing house control. Additionally, the securities purchased subject to reverse repurchase have a market value greater than the reverse repurchase amount. The typical haircut received for high quality sovereign debt is 2% of the reverse repurchase amount. Thus, in the event that a reverse repurchase counterparty defaults on its obligation to repurchase the underlying reverse repurchase securities, our clearing house will have possession of securities with a value potentially greater than the reverse repurchase counterparty’s obligation to the clearing house. ICE Clear Credit has been designated as a systemically important financial market utility by the Financial Stability Oversight Council and has been authorized to establish and maintain a cash account at the Federal Reserve Bank of Chicago. Such account was opened on July 30, 2015 and it is intended to decrease ICE Clear Credit's custodial, liquidity and operational risk as compared to alternative custodial and investment arrangements. Our futures businesses have minimal credit risk as all of their transaction revenues are currently cleared through our clearing houses. Our accounts receivable related to market data revenues, cash trading, listing revenues, technology revenues, CDS transaction revenues and bilateral over-the-counter energy transaction revenues subjects us to credit risk, as we do not require these customers to post collateral. We limit our risk of loss by terminating access to trade to entities with delinquent accounts. The concentration of risk on accounts receivable is also mitigated by the large number of entities comprising our customer base. Our accounts receivable are stated at cost. Excluding clearing members, there were no individual accounts receivable balances greater than 10% of total consolidated accounts receivable as of December 31, 2016 or December 31, 2015 . No single customer accounted for more than 10% of total consolidated revenues during any of the years ended December 31, 2016 , 2015 or 2014 .
Leases	Leases We expense rent from non-cancellable operating leases, net of sublease income, on a straight-line basis based on future minimum lease payments. The net costs are included in rent and occupancy expenses and technology and communication expenses in the accompanying consolidated statements of income (Note 13).
Acquisition-Related Transaction and Integration Costs	Acquisition-Related Transaction and Integration Costs We incurred incremental direct acquisition-related transaction costs relating to various completed and potential acquisitions and other strategic opportunities to strengthen our competitive position and support growth. The acquisition-related transaction costs include fees for investment banking advisors, lawyers, accountants, tax advisors and public relations firms, deal-related bonuses to certain of our employees, as well as costs associated with credit facilities and other external costs directly related to the proposed or closed transactions. We also incurred integration costs during the years ended December 31, 2016, 2015 and 2014 relating to our integration of NYSE and during the year ended December 31, 2016 relating to our integration of Interactive Data. Integration costs primarily related to employee termination costs, costs incurred relating to the IPO and sale of Euronext in Europe and the sale of NYSE Technologies, deal related bonuses, lease termination costs and professional services costs incurred relating to the integrations. The acquisition-related transaction and integration costs incurred during the year ended December 31, 2016 primarily relate to the integration costs incurred for our Interactive Data and NYSE integrations, legal and professional fees related to the Trayport CMA review, our investment in MERS, our acquisition of Securities Evaluations and Credit Market Analysis, and various other potential and discontinued acquisitions. As of December 31, 2016, the integration of NYSE has been completed. The acquisition-related transaction and integration costs incurred during the year ended December 31, 2015 primarily relate to the integration costs incurred for our NYSE integration and the acquisition-related transaction costs related to our Interactive Data and Trayport acquisitions. The acquisition-related transaction and integration costs incurred during the year ended December 31, 2014 primarily relate to the acquisition and integration costs incurred for NYSE and the acquisition-related transaction costs related to our SuperDerivatives, ICE Futures Singapore, ICE Clear Netherlands and True Office acquisitions.
Foreign Currency Translation Adjustments and Foreign Currency Transaction Gains and Losses	Foreign Currency Translation Adjustments and Foreign Currency Transaction Gains and Losses Our functional and reporting currency is the U.S. dollar. We have foreign currency translation risk equal to our net investment in certain U.K., continental European, Asian and Canadian subsidiaries. The revenues, expenses and financial results of these subsidiaries are recorded in the functional currency of the countries that these subsidiaries are located in, which are primarily pounds sterling and euros. The financial statements of these subsidiaries are translated into U.S. dollars using a current rate of exchange, with gains or losses, net of tax as applicable, included in the cumulative translation adjustment account, a component of equity. As of December 31, 2016 and 2015 , the portion of our equity attributable to accumulated other comprehensive loss from foreign currency translation adjustments was $345 million and $45 million , respectively. We have foreign currency transaction gains and losses related to the settlement of foreign currency denominated assets, liabilities and payables that occur through our operations, which are received in or paid in pounds sterling or euros. The transaction gain and losses are due to the increase or decrease in the foreign currency exchange rates between periods. Forward contracts on foreign currencies are entered into to manage the foreign currency exchange rate risk. Gains and losses from foreign currency transactions are included in other income (expense) in the accompanying consolidated statements of income and resulted in net losses of $1 million , $14 million and $2 million for the years ended December 31, 2016 , 2015 and 2014 , respectively.
Earnings Per Common Share	Earnings Per Common Share Basic earnings per common share is calculated using the weighted average common shares outstanding during the year. Common equivalent shares from stock options and restricted stock awards, using the treasury stock method, are included in the diluted per share calculations unless the effect of inclusion would be antidilutive (Note 19).
Stock Split [Policy Text Block]
Fair Value of Financial Instruments	Fair Value of Financial Instruments We apply fair value accounting for all financial assets and liabilities and non-financial assets and liabilities that are recognized or disclosed at fair value in the financial statements on a recurring basis (Note 15). Fair value is the price that would be received from selling an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date. Our financial instruments consist primarily of cash and cash equivalents, short-term and long-term restricted cash and investments, short-term and long-term investments, customer accounts receivable, margin deposits and guaranty funds, short-term and long-term debt and other short-term assets and liabilities.
Recently Adopted and New Accounting Pronouncements	Recently Adopted and New Accounting Pronouncements In May 2014, the Financial Accounting Standards Board, or FASB, issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers (Topic 606) , or ASU 606. ASU 606 provides guidance outlining a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers that supersedes most current revenue recognition guidance. This guidance requires us to recognize revenue when we transfer promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The original effective date of the guidance would have required us to adopt at the beginning of our first quarter of fiscal 2017; however, the FASB approved an optional one-year deferral of the effective date. Additionally, the new guidance requires enhanced disclosures, including revenue recognition policies to identify performance obligations to customers and significant judgments in measurement and recognition. The new guidance may be applied retrospectively to each prior period presented or retrospectively with the cumulative effect recognized as of the date of adoption. We are currently evaluating the overall impact this guidance will have on our consolidated financial statements, as well as the method of adoption. Based on our preliminary assessment, we expect that the adoption may accelerate the timing of recognition of original and supplemental listing fees related to our NYSE businesses, which are currently deferred over a pre-defined customer life of five or nine years. We are continuing our assessment, which may identify other impacts of the adoption of ASU 606. In April 2015, the FASB issued Accounting Standards Update No. 2015-03, Simplifying the Presentation of Debt Issuance Costs, or ASU 2015-03. This standard amends the existing guidance to require that debt issuance costs be presented in the balance sheet as a deduction from the carrying amount of the related debt liability instead of as a deferred asset. The amortization of the debt issuance costs will continue to be expensed as interest expense over the term of the related debt. ASU 2015-03 will be effective on a retrospective basis for annual reporting periods beginning after December 15, 2015, but early adoption is permitted. We decided to early adopt ASU 2015-03 on a retrospective basis for the annual period ended December 31, 2015 and the adoption did not have a material effect on our consolidated financial statements. See Note 9 for disclosure and related impact to the consolidated financial statements under this new guidance. In November 2015, the FASB issued Accounting Standards Update, Balance Sheet Classification of Deferred Taxes, or ASU 2015-17. ASU 2015-17 is part of the FASB’s simplification initiative aimed at reducing complexity in accounting standards. This new standard requires that all deferred tax assets and liabilities, along with any related valuation allowance, be classified as non-current on the balance sheet. ASU 2015-17 was required to be effective on a retrospective basis for annual reporting periods beginning after December 15, 2016, but early adoption is permitted. We decided to early adopt ASU 2015-17 on a retrospective basis for the annual period ended December 31, 2015 and the adoption did not have a material effect on our consolidated financial statements. See Note 11 for deferred taxes disclosure and related impact to the consolidated financial statements under this new guidance. In January 2016, the FASB issued Accounting Standards Update No. 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities, or ASU 2016-01. ASU 2016-01 provides updated guidance for the recognition, measurement, presentation, and disclosure of certain financial assets and liabilities, including the requirement that equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) are to be measured at fair value with changes in fair value recognized in net income. ASU 2016-01 is effective for annual and interim reporting periods beginning after December 15, 2017. On the adoption of ASU 2016-01, changes in the fair value of our equity investment in Cetip will no longer be reflected in accumulated other comprehensive income but will be recognized in net income. As of December 31, 2016, our investment in Cetip included an accumulated unrealized gain of $108 million (Note 5). During the year ended December 31, 2016, the change in the fair value of the Cetip investment was an increase of $134 million . Once adopted, such fair value changes will be reported as other income (expense) under ASU 2016-01. We are currently evaluating this guidance to determine any additional potential impact on our consolidated financial statements upon adoption. In February 2016, the FASB issued Accounting Standards Update No. 2016-02, Leases, or ASU 2016-02. ASU 2016-02 requires an entity to recognize both assets and liabilities arising from financing and operating leases, along with additional qualitative and quantitative disclosures. A lessee should recognize in its balance sheet a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term. 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. ASU 2016-02 is effective for annual and interim reporting periods beginning after December 15, 2018, with early adoption permitted. We are currently evaluating this guidance to determine the potential impact on our consolidated financial statements and whether we will adopt this guidance early. In March 2016, the FASB issued Accounting Standards Update No. 2016-09, Stock Compensation (Topic 718) - Improvements to Employee Share-Based Payment Accounting , or ASU 2016-09. ASU 2016-09 provides updated guidance for the recognition, measurement, presentation, and disclosure of certain components of stock compensation. The guidance includes the recognition of all excess tax benefits/deficiencies in the statement of income and classification as operating activities within the statement of cash flows, as well as the option to account for forfeitures based on awards expected to vest or as they occur. ASU 2016-09 is effective for annual and interim reporting periods beginning after December 15, 2017, with early adoption permitted. We elected to early adopt ASU 2016-09 in the first quarter of 2016 on a prospective basis. As a result, for the year ended December 31, 2016, we recorded $15 million in excess tax benefits within our consolidated statement of income. No other terms of the adopted guidance resulted in any significant impact on our consolidated financial statements. In November 2016, the FASB issued Accounting Standards Update No. 2016-18, Statement of Cash Flows: Restricted Cash , or ASU 2016-18, that will require entities to show the changes in the total of cash, cash equivalents, restricted cash and restricted cash equivalents in the statement of cash flows. As a result, entities will no longer present transfers between cash and cash equivalents and restricted cash and restricted cash equivalents in the statement of cash flows. When cash, cash equivalents, restricted cash and restricted cash equivalents are presented in more than one line item on the balance sheet, the new guidance requires a reconciliation of the totals in the statement of cash flows to the related captions in the balance sheet. This reconciliation can be presented either on the face of the statement of cash flows or in the notes to the financial statements. Entities will also have to disclose the nature of their restricted cash and restricted cash equivalent balances. ASU 2016-18 becomes effective for us in fiscal years beginning after December 15, 2017, and interim periods within those years, with early adoption permitted. Early adoption in an interim period is permitted, but any adjustments must be reflected as of the beginning of the fiscal year that includes that interim period. We will be required to apply the guidance retrospectively when adopted, and provide the relevant disclosures in the first interim and annual periods in which we adopt the guidance. We have not yet determined if we will adopt ASU 2016-18 early, but do expect to be impacted by the new presentation and disclosure requirements required by ASU 2016-18 due to our restricted and unrestricted cash balances.
