	Summary of Significant Accounting Policies
	Basis of Presentation
	The accompanying unaudited consolidated financial statements have been prepared by the Company in accordance with United States (“U.S.”) generally accepted accounting principles (“U.S. GAAP”) pursuant to the rules and regulations of the Securities and Exchange Commission regarding interim financial reporting. Accordingly, the unaudited consolidated financial statements do not include all of the information and footnotes required by U.S. GAAP for complete financial statements and should be read in conjunction with the Company’s audited consolidated financial statements and related notes thereto for the year ended December 31, 2013. The accompanying unaudited consolidated financial statements reflect all adjustments that are, in the opinion of the Company’s management, necessary for a fair presentation of results for the interim periods presented. These adjustments are of a normal recurring nature.
	Preparing financial statements requires management to make estimates and assumptions that affect the amounts that are reported in the consolidated financial statements and accompanying disclosures. Although these estimates are based on management’s best knowledge of current events and actions that the Company may undertake in the future, actual results may be different from these estimates. The results of operations for the three months ended March 31, 2014 are not necessarily indicative of the results to be expected for any future period or the full fiscal year.
	The accompanying unaudited consolidated financial statements include the accounts of the Company and its wholly-owned and controlled subsidiaries. All intercompany balances and transactions between the Company and its wholly-owned and controlled subsidiaries have been eliminated in consolidation. As discussed in Note 3, the Company completed an acquisition during the three months ended March 31, 2014 and has included the financial results of this company in its consolidated financial statements effective from the acquisition date.
	For those consolidated subsidiaries in which the Company’s ownership is less than 100% and for which the Company has control over the assets and liabilities and the management of the entity, the outside stockholders’ interests are shown as non-controlling interests.
	Segment Information
	The Company previously operated as a single reportable business segment as of December 31, 2013. As of March 31, 2014, the Company is reporting two business segments, the ICE segment and the Euronext segment, which is reflective of how the Company's chief operating decision maker reviews and operates the business (Note 15). The Company plans to spin the Euronext segment off in an initial public offering in the second quarter of 2014, subject to certain regulatory approvals and other conditions, and expects to revert to one operating segment after the initial public offering.

	Acquisitions
	NYSE Euronext Acquisition
	On November 13, 2013, the Company acquired 100% of NYSE Euronext for a combination of cash and stock. The total purchase price was $11.1 billion and included cash consideration of $2.7 billion and the issuance of 42.4 million shares of the Company's common stock to NYSE Euronext stockholders. The fair value of the shares issued was $8.4 billion based on the closing share price of the Company's common stock of 197.80 per share on November 12, 2013.
	Under purchase accounting, the total purchase price was allocated to NYSE Euronext’s preliminary net tangible and identifiable intangible assets based on the estimated fair values of those assets as of November 13, 2013, as set forth below. The excess of the purchase price over the preliminary net tangible and identifiable intangible assets was recorded as goodwill. Goodwill represents potential revenue synergies related to clearing and new product development, expense synergies related to technology and clearing, and opportunities to enter new markets. The preliminary purchase price allocation is as follows (in millions):
	Property and equipment	641
	Goodwill	7,394
	Identifiable intangible assets	8,521
	Other assets and liabilities, net	152
	Deferred tax liabilities on identifiable intangible assets	(2,763		)
	Short-term and long-term debt	(2,529		)
	Non-controlling interests	(327		)
	Total preliminary purchase price allocation	$	11,089
	In performing the preliminary purchase price allocation, the Company considered, among other factors, the intended future use of acquired assets, analysis of historical financial performance and estimates of future performance of NYSE Euronext’s business. The preliminary allocation of the purchase price will be finalized upon the completion of the fair value analysis of the acquired assets and liabilities, including the preliminary intangible assets. During the first quarter of 2014, the Company adjusted the preliminary purchase price allocation based on updated fair value analyses of the NYSE Euronext tangible and intangible assets and liabilities. The fair value adjustments reflected in the tables above and below, primarily result in an increase in the customer relationships intangible assets of $60 million, an increase in the deferred tax liabilities on identifiable intangible assets of $29 million and a corresponding decrease to goodwill of $28 million. The income statement impact for 2013 relating to these fair value adjustments is not significant. The Company has 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 and certain other tangible assets and liabilities, and the allocation of the goodwill to the various reporting units.
	The following table sets forth the components of the preliminary intangible assets and the net book value as of March 31, 2014 (in millions, except years):
	Preliminary Intangible Assets		Preliminary		Foreign Currency Translation		Accumulated Amortization			Net Book
			Acquisition-Date Fair Value							Value		Useful Life
	Exchange registrations and licenses		$	6,960	$	154	$	—		$	7,114	Indefinite

	Developed technology		113		1		(14		)	100		3 years
	Total		$	8,521	$	179	$	(36	)	$	8,664
	The Company has incurred $30 million in employee termination costs during the three months ended March 31, 2014 following the acquisition, which are included in acquisition-related transaction and integration costs.
	The financial information in the table below summarizes the combined results of operations of the Company and NYSE Euronext, on a pro forma basis, as though the companies had been combined as of January 1, 2013. 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 the Company and NYSE Euronext. 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, preliminary purchase accounting adjustments. The pro forma financial information does not reflect any synergies or operating cost reductions that may be achieved from the combined operations. The pro forma financial information combines the historical results for the Company and NYSE Euronext for the three months ended March 31, 2013 in the following table (in millions, except per share amounts):
	Total revenues, less transaction-based expenses	$	927
	Operating income	$	412
	Net income attributable to the Company	$	265
	Earnings per common share — Basic	$	2.31
	Earnings per common share — Diluted	$	2.3
	SMX Acquisition
	On February 3, 2014, the Company acquired 100% of Singapore Mercantile Exchange Pte. Ltd. (“SMX”). The acquisition includes Singapore Mercantile Exchange Clearing Corporation Pte. Ltd. (“SMXCC”), a wholly owned subsidiary of SMX, and the clearing house for all SMX trades. SMX operates futures markets in Singapore across metals, currencies, energy and agricultural commodities and SMXCC clears the contracts executed on SMX. SMX and SMXCC retain licenses to operate as an approved exchange and an approved clearing house, regulated by the Monetary Authority of Singapore. These licenses provide the Company with exchange and clearing licenses in Asia. The exchange and clearing infrastructures are expected to transition to the ICE trading and clearing platforms in the second half of 2014. As a result, a period of business transition is currently underway and the exchange and clearing house have been temporarily shut down and are expected to re-launch by year end. The financial results of SMX are not expected to be material to the 2014 results for the Company. On April 22, 2014, SMX and SMXCC were renamed ICE Futures Singapore and ICE Clear Singapore, respectively.
	The SMX purchase price was allocated to the preliminary net tangible and identifiable intangible assets based on the preliminary fair value of those assets as of February 3, 2014. The preliminary net tangible and identifiable intangible assets acquired were $49 million. The Company has recorded preliminary intangible assets of $31 million for exchange registrations and licenses, which have been assigned an indefinite life. The excess of the purchase price over the preliminary net tangible and identifiable intangible assets was $101 million and was recorded as goodwill.
	The preliminary allocation of the purchase price will be finalized upon the completion of the fair value analysis of the acquired assets and liabilities, including the preliminary intangible assets. The Company has 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 and certain other tangible assets and liabilities.

The other activity, net in the tables above results from adjustments to the fair value of the net tangible and identifiable intangible assets and liabilities relating to the NYSE Euronext acquisition, with a corresponding charge to goodwill (Note 3). The Company did not recognize any impairment losses on goodwill or other intangible assets during the three months ended March 31, 2014 and 2013.

	2014 Credit Facility
	On April 3, 2014, the Company, as parent borrower, and its subsidiary ICE Europe Parent Limited, as subsidiary borrower, entered into a new $3.0 billion senior unsecured revolving credit facility (the “2014 Credit Facility”) pursuant to a credit agreement dated as of April 3, 2014 with Wells Fargo Bank, National Association ("Wells Fargo"), as administrative agent, issuing lender and swingline lender, Bank of America, N.A., as syndication agent, and the lenders party thereto. The 2014 Credit Facility includes an option for the Company to propose an increase in the aggregate amount by up to $1.0 billion, subject to the consent of the lenders funding the increase and certain other conditions. The Company incurred $11 million in debt issuance costs in connection with the 2014 Credit Facility, which will be amortized over the term of the agreement.
	The 2014 Credit Facility matures on April 3, 2019. Amounts borrowed under the 2014 Credit Facility may be prepaid at any time without premium or penalty. The 2014 Credit Facility provides for a $3.0 billion multi-currency revolving facility, with sub-limits for non-dollar borrowings, swingline borrowings and letters of credit. No amounts have been drawn under the 2014 Credit Facility. As of April 3, 2014, of the $3.0 billion that was available for borrowing under the 2014 Credit Facility, $1.3 billion is required to back stop the amount outstanding at that time under the Company's commercial paper program and $303 million is reserved for our clearing houses, both as discussed below. As of April 3, 2014, the remaining $1.4 billion is available to the Company to use for working capital and general corporate purposes, and any portion of the revolving credit facility no longer necessary in the future to be reserved for the foregoing purposes will be available to the Company to use for working capital and general corporate purposes.
	Borrowings under the 2014 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 the Company’s public long term debt ratings and ranges from 0.875% to 1.5% on LIBOR borrowings and from 0.00% to 0.50% on base rate borrowings.
	The 2014 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 0.080% to 0.200% and is determined based on the Company's long term debt rating. As of April 3, 2014, the applicable commitment fee rate was 0.125% based on the Company’s current long term debt ratings.
	Of the amounts available under the 2014 Credit Facility: (i) $150 million of such amounts has been reserved to provide liquidity or required financial resources for the clearing operations of ICE Clear Europe, (ii) $100 million of such amounts has been reserved to provide liquidity or required financial resources for the clearing operations of ICE Clear Credit, (iii) $50 million of such amounts has been reserved to provide liquidity or required financial resources for the clearing operations of ICE Clear U.S., and (iv) $3 million of such amounts has been reserved to provide liquidity or required financial resources for the clearing operations of ICE Clear Canada. From time to time, the Company may agree to provide additional liquidity to its subsidiaries to meet regulatory capital requirements, general corporate purposes or short term liquidity needs.
	The 2014 Credit Facility contains customary representations and warranties, covenants and events of default, including a leverage ratio, as well as limitations on liens on the Company's assets, indebtedness of non-obligor subsidiaries, the sale of all or substantially all of the Company's assets, and other matters.
	Revolving Facility and Term Loan Facility (2011 Credit Facilities)
	In November 2011, the Company entered into senior unsecured credit facilities in the aggregate amount of $2.6 billion (the “2011 Credit Facilities”). The 2011 Credit Facilities consisted of (i) an aggregate $500 million five-year senior unsecured term loan facility (the “Term Loan Facility”) and (ii) an aggregate $2.1 billion five-year senior unsecured multicurrency revolving credit facility (the “Revolving Facility”). The 2011 Credit Facilities were scheduled to mature on November 9, 2016. As of March 31, 2014, the Company had $367 million aggregate principal amount of borrowings outstanding under the Term Loan Facility, in the form of a LIBOR rate loan with a stated interest rate of 2.0275% per annum.
	In connection with the Company entering into the 2014 Credit Facility on April 3, 2014, the 2011 Credit Facilities were terminated and the $367 million outstanding under the Term Loan Facility was repaid through the issuance of new commercial paper, as discussed below. As of March 31, 2014, the $367 million was reflected as short-term debt and there were no amounts were outstanding under the Revolving Facility.
	364 Day Facility
	In July 2013, the Company entered into a $600 million 364 day senior unsecured revolving credit facility (the “364 Day Facility”). The 364 Day Facility was available for working capital and general corporate purposes. In connection with the Company entering into the 2014 Credit Facility, the 364 Day Facility was terminated on April 3, 2014, at which time no amounts were outstanding.
	Commercial Paper Program
	In December 2013, the Company entered into a U.S. dollar commercial paper program (the “Commercial Paper Program”). The Commercial Paper Program is currently backed by the borrowing capacity available under the 2014 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 therefore impact the interest expense incurred by the Company.
	Commercial paper notes of $930 million and original maturities ranging from 1 to 60 days were outstanding as of March 31, 2014 under the Commercial Paper Program. As of March 31, 2014, the weighted average interest rate on the $930 million outstanding under the Commercial Paper Program was 0.33% per annum, with a weighted average maturity of 35 days. The Company used the net proceeds from $367 million in new commercial paper issued under the Commercial Paper Program on April 1, 2014 to repay the $367 million that was outstanding under the Term Loan Facility as discussed above.
	Senior Notes and NYSE Euronext Notes
	In October 2013, the Company issued $600 million aggregate principal amount of 2.50% senior unsecured fixed rate notes due October 2018 (the “2018 Senior Notes”) and $800 million aggregate principal amount of 4.00% senior unsecured fixed rate notes due October 2023 (the “2023 Senior Notes”, together with the 2018 Senior Notes, the “Senior Notes”). In connection with the acquisition of NYSE Euronext, one of the Company's subsidiaries assumed the outstanding NYSE Euronext debt instruments, which included $850 million of 2.0% senior unsecured fixed rate notes due in October 2017 (the “NYSE Euronext USD Notes”) and €920 million ($1.3 billion) of 5.375% senior unsecured fixed rate notes due in June 2015 (the “NYSE Euronext EUR Notes”, and together with the NYSE Euronext USD Notes, the "NYSE Euronext Notes").

	Equity
	The Company currently sponsors employee and director stock option and restricted stock plans. Stock options and restricted stock are granted at the discretion of the compensation committee of the board of directors. All stock options and restricted stock awards 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. The fair value of the stock options and restricted stock on the date of grant is recognized as expense over the vesting period, net of estimated forfeitures. The non-cash compensation expenses recognized in the Company’s consolidated statements of income for stock options and restricted stock were $17 million and $15 million for the three months ended March 31, 2014 and 2013, respectively. The following is a summary of stock options for the three months ended March 31, 2014:
		Number of Options			Weighted Average
					Exercise Price per
					Option
	Outstanding at December 31, 2013	872,347			$	97.92
	Granted	154,202			206.87
	Exercised	(66,593	)		37.11
	Outstanding at March 31, 2014	959,956			119.64
	Details of stock options outstanding as of March 31, 2014 are as follows:
		Number of Options			Weighted Average				Weighted Average	Aggregate
					Exercise Price				Remaining	Intrinsic
									Contractual Life	Value
									(Years)	(In millions)
	Vested or expected to vest	959,956			$	119.64			6	$	76
	Exercisable	690,712			$	99.21			4.8	$	68
	The total intrinsic value of stock options exercised during the three months ended March 31, 2014 and 2013 was $12 million and $7 million, respectively. As of March 31, 2014, there were $11 million in total unrecognized compensation costs related to stock options. These costs are expected to be recognized over a weighted average period of 2.3 years as the stock options vest.
	The Company uses the Black-Scholes option pricing model for purposes of valuing stock option awards. During the three months ended March 31, 2014 and 2013, the Company used the weighted-average assumptions in the table below to compute the value of all options for shares of common stock granted to employees:
			Three Months Ended March 31,
	Assumptions		2014				2013
	Risk-free interest rate		1.23		%		0.53		%
	Expected life in years		5				4
	Expected volatility		27		%		37		%
	Expected dividend yield		1.26		%		0		%
	Estimated weighted-average fair value of options granted per share		$	45.23			$	38.41
	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 the Company’s stock. Expected dividend yields have historically been 0% prior to the November 13, 2013 acquisition of NYSE Euronext since the Company did not (and had not contemplated) paying a dividend prior to the acquisition of NYSE Euronext. The Company's new dividend policy will impact the expected dividend yield on all stock options granted post-acquisition.
	In February 2014, the Company reserved a maximum of 351,310 restricted shares for potential issuance as performance-based restricted shares to certain Company employees. The number of shares that will ultimately be granted under the performance awards will be based on the Company’s actual financial performance as compared to financial performance targets set by the Company’s board of directors and compensation committee for the year ending December 31, 2014. These restricted shares are also subject to a market condition that could reduce the number of shares that are ultimately granted. The reduction would occur if the Company’s 2014 total shareholder return falls below the 2014 return of the S&P 500 Index and the Company achieves an above “target” financial performance level threshold. If the Company’s 2014 total shareholder return were to fall below the 2014 return of the S&P 500 Index, the reduction would be either 10% or 20% of the number of shares granted, depending on the difference in the aforementioned returns.
	The grant date of this award was February 27, 2014, which was the date when the Company and the employees reached a mutual understanding of award terms. February 27, 2014 is also 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 $71 million if the maximum financial performance target is met and all 351,310 shares vest. The compensation expense to be recognized under these performance-based restricted shares will be $35 million if the target financial performance is met, which would result in 175,655 shares vesting. The Company will recognize expense on an accelerated basis over the three-year vesting period based on the Company’s quarterly assessment of the probable 2014 actual financial performance as compared to the 2014 financial performance targets. If the market condition is not achieved, compensation cost will not be affected since the grant date fair value of the award gave consideration to the probability of market condition achievement.
	As of March 31, 2014, the Company determined that it is probable that the target financial performance level will be met for 2014. Based on this assessment as of March 31, 2014, the Company recorded non-cash compensation expense of $2 million for the three months ended March 31, 2014 related to these shares and the remaining $33 million in non-cash compensation expense will be recorded on an accelerated basis over the remaining vesting period, including $16 million of which will be recorded over the remainder of 2014.
	The following is a summary of the non-vested restricted shares for the three months ended March 31, 2014:
		Number of		Weighted Average
		Restricted		Grant-Date Fair
		Stock Shares		Value per Share
	Non-vested at December 31, 2013	1,234,552		$	147
	Granted	415,097		206.2
	Vested	-393,728		119.15
	Forfeited	-12,592		140.41
	Non-vested at March 31, 2014	1,243,329		175.65
	Restricted stock shares granted in the table above include both time-based and performance-based grants. Performance-based shares have been adjusted 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 March 31, 2014, there were $160 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 2.5 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 February 2014. During the three months ended March 31, 2014 and 2013, the total fair value of restricted stock vested under all restricted stock plans was $84 million and $50 million, respectively.

	Income Taxes from Continuing Operations
	The Company’s effective tax rate from continuing operations was 28% for both the three months ended March 31, 2014 and 2013. The effective tax rates for the three months ended March 31, 2014 and 2013 are lower than the federal statutory rate primarily due to favorable foreign tax rate differentials, partially offset by state income taxes. Favorable foreign income tax rate differentials result primarily from lower tax rates in the United Kingdom, the Netherlands and various other lower tax jurisdictions.
	The Company’s non-U.S. subsidiaries had $1.8 billion billion in cumulative undistributed earnings as of March 31, 2014. This amount represents the post-income tax earnings under U.S. GAAP adjusted for previously taxed income. The earnings from the Company’s 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 the Company 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.

Clearing Organizations	'
	Clearing Organizations
	The Company operates six regulated central counterparty clearing houses for the settlement and clearance of derivative contracts. The six central counterparty clearing houses include ICE Clear Europe, ICE Clear U.S., ICE Clear Canada, ICE Clear Credit, The Clearing Corporation ("TCC") and ICE Clear Singapore, and are referred to herein collectively as the “ICE Clearing Houses”.
	Each of the ICE Clearing Houses requires all clearing members to maintain cash on deposit or pledge certain assets, which may include government obligations, letters of credit, gold or emission allowances to guarantee performance on 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 in respect of marking to market 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 our 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 (“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 or settled on at least a daily basis for each clearing member, the ICE Clearing Houses’ maximum estimated exposure for this guarantee, excluding the risk management program discussed below, is $59.9 billion as of March 31, 2014, 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 $2.7 trillion as of March 31, 2014. The Company performed calculations to determine the fair value of its counterparty performance guarantee taking into consideration factors such as daily settlement of contracts, margining requirements, other elements of the Company’s 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 March 31, 2014 and December 31, 2013.
	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 margin or risk committees, risk management departments and the boards of directors of each of the ICE Clearing Houses and may fluctuate over time. As of March 31, 2014 and December 31, 2013, the ICE Clearing Houses have received or have been pledged $74.5 billion and $68.2 billion, respectively, in cash and non-cash collateral in original margin, unsettled variation margin, performance collateral for delivery and Guaranty Fund deposits to cover price movements of underlying contracts. 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 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 margin and Guaranty Fund deposits to make up the 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 all clearing members on a pro-rata basis for that purpose. The Company has contributed $110 million, $50 million and $50 million to the ICE Clear Europe, ICE Clear Credit and ICE Clear U.S. Guaranty Funds, respectively, as of March 31, 2014, 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. The $210 million combined contributions as of March 31, 2014 are included in long-term restricted cash in the accompanying consolidated balance sheet and includes $50 million contributed to ICE Clear U.S. on January 1, 2014 (Note 4).
	As of March 31, 2014, original margin and Guaranty Fund cash deposits are as follows for the ICE Clearing Houses (in millions):
		ICE Clear U.S.		ICE Clear		ICE Clear		ICE Clear		TCC and ICE Clear Singapore		Total

	Total	$	1,884	$	24,549	$	72	$	15,708	$	3	$	42,216
	The Company has 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, securities and letters of credit are available only to meet the financial obligations of that clearing member to the relevant ICE Clearing House. ICE Clear U.S., ICE Clear Europe, ICE Clear Canada, ICE Clear Credit, TCC 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.
	The $17.2 billion of ICE Clear Credit cash deposits as of March 31, 2014 primarily represent funds invested under reverse repurchase agreements with several counterparty banks, none of which are clearing members, through a third party custodian bank. Under these arrangements, ICE Clear Credit purchases U.S. Treasury securities and other U.S. securities and the various counterparties agree to repurchase the instruments the following business day at a set price, plus interest. Of the $22.2 billion of ICE Clear Europe cash deposits as of March 31, 2014, $19.6 billion represent funds invested under reverse repurchase agreements through two third party investment and custody agents, with several different counterparty banks, some of which are also our clearing members and are large commercial financial institutions, and $2.6 billion represent funds invested directly in sovereign debt. Under these arrangements, ICE Clear Europe primarily purchases U.S. Treasury securities and certain sovereign debt obligations from the seven largest industrialized nations, and the various counterparties agree to repurchase the instruments on the set repurchase date at the set repurchase price, plus interest. The carrying value of these securities approximates their fair value due to the short-term nature of the instruments and repurchase agreements. The remaining cash deposits at the ICE Clearing Houses are held in demand deposit accounts at various financial institutions.
	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 may include government obligations, letters of credit, gold or emission allowances to mitigate its 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. These assets are held in safekeeping and any interest and gain or loss accrues to the clearing member. For certain non-cash deposits, the ICE Clearing Houses may impose haircut rates to ensure adequate collateral levels to account for fluctuations in the market value of these deposits. As of March 31, 2014 and December 31, 2013, 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):

	Legal Proceedings
	The Company is subject to legal proceedings and claims, like the ones described below, that arise in the ordinary course of business. Typically, the Company does not believe that the resolution of these matters will have a material adverse effect on the Company’s 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.
	On April 18, 2014, a purported class action lawsuit was filed in the U.S. District Court for the Southern District of New York (the "Southern District") by the City of Providence, Rhode Island, against more than 40 defendants, including "Exchange Defendants", "Brokerage Defendants" and “HFT [High Frequency Trading] Defendants”. New York Stock Exchange LLC and NYSE Arca, Inc., two of the Company's subsidiaries, are among the named Exchange Defendants. Plaintiff is suing on behalf of a class of “all public investors” who bought  or sold stock on a U.S.-based exchange or alternative trading venue from April 18, 2009 to the present. The complaint asserts violations by all Exchange Defendants of Sections 10(b) and 6(b) of the Securities Exchange Act of 1934. The complaint seeks unspecified compensatory damages against all defendants, jointly and severally, as well as various forms of equitable relief. On May 2, 2014, a purported class action lawsuit with similar allegations and legal claims was filed in the Southern District by American European Insurance Company against most of the same entities (including New York Stock Exchange LLC and NYSE Arca, Inc.) named as defendants in the City of Providence lawsuit. Additional information may be obtained from the complaints, which are styled, respectively, as City of Providence v. BATS Global Markets, Inc. et al., Case No. 14-cv-2811 (S.D.N.Y.), and American European Insurance Company v. BATS Global Markets, Inc. et al., Case No. 14-cv-3133 (S.D.N.Y.). The ultimate outcome of these matters cannot reasonably be predicted at this time.
	Tax Audits
	The Company is 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 the Company or one of its subsidiaries, some of which may not be resolved for several years. Based on currently available information, the Company believes it has adequately provided for any assessments that could result from those proceedings where it is more likely than not that the Company will be assessed. The Company continuously reviews its positions as these matters progress.

Fair Value Disclosures [Abstract]	'
Fair Value Measurements	'
	Fair Value Measurements
	The Company’s 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 other short-term assets and liabilities. The fair value of the Company’s 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.
	In general, the Company uses 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 supplemental executive retirement plan and supplemental executive savings plan. The fair value of each of these assets are based on quoted prices. If quoted prices are not available to determine fair value, the Company uses other inputs that are observable either directly or indirectly. Level 2 assets consist of foreign exchange derivative contracts not designated as hedging instruments. Such values are based on published currency rates. As of March 31, 2014, the fair values of the Company’s $1.39 billion Senior Notes and $2.19 billion NYSE Euronext Notes are $1.44 billion and $2.2 billion, respectively. The fair values of these fixed rate notes were estimated using quoted market prices for these instruments. The fair value of the Company’s other short-term and long-term debt approximates the carrying value since the rates of interest on the debt approximate market rates as of March 31, 2014. All other financial instruments are determined to approximate carrying value due to the short period of time to their maturities.
	Financial assets and liabilities recorded in the accompanying consolidated balance sheets as of March 31, 2014 and December 31, 2013 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 March 31, 2014 are as follows (in millions):
		Level 1		Level 2		Total
	Assets at fair value:
	Long-term investment in equity securities	$	384	$	—	$	384
	U.S. Treasury securities	75		—		75
	Mutual Funds	28		—		28
	Foreign exchange derivative contracts	—		1		1
	Total assets at fair value	$	487	$	1	$	488
	Financial instruments measured at fair value on a recurring basis as of December 31, 2013 are as follows (in millions):
		Level 1		Level 2		Total
	Assets at fair value:
	Long-term investment in equity securities	$	324	$	—	$	324
	U.S. Treasury securities	100		—		100
	Mutual Funds	33		—		33
	Foreign exchange derivative contracts	—		4		4
	Total assets at fair value	$	457	$	4	$	461
	The long-term investment in equity securities as of March 31, 2014 and December 31, 2013 represents the Company's 12% investment in Cetip, S.A., recorded at its fair value using its quoted market price. The mutual funds represent equity and fixed income mutual funds held for the purpose of providing future payments to the supplemental executive retirement plan and supplemental executive savings plan. As of March 31, 2014, the Company is holding $75 million in U.S. Treasury securities, all of which had maturities of less than one year from the date of purchase. The Company accounts for these U.S. Treasury securities using the available-for-sale method. Of these U.S. Treasury securities, $26 million are recorded as short-term investments and $49 million are recorded as short-term restricted cash and investments in the accompanying consolidated balance sheet as of March 31, 2014.
	The Company did not use Level 3 inputs to determine the fair value of assets or liabilities measured at fair value on a recurring basis as of March 31, 2014 and December 31, 2013. The Company measures 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 March 31, 2014 and December 31, 2013, none of these assets were required to be recorded at fair value since no impairment indicators were present. Cost and equity method investments were $177 million as of both March 31, 2014 and December 31, 2013.

	Discontinued Operations
	Following the Company’s acquisition of NYSE Euronext in November 2013, the Company evaluated the long-term strategy and financial performance of NYSE Euronext’s commercial technology business, NYSE Technologies, which provides comprehensive transaction, data and infrastructure services and managed solutions for buy-side, sell-side and exchange communities. NYSE Technologies operates five business lines: Global Market Data, Global Connectivity, Exchange Solutions, Trading Solutions and Transaction Services. The Company is integrating Global Market Data and Global Connectivity into its operations where they will be integrated with the exchange businesses and technology infrastructure. Exchange Solutions was transferred to Euronext as part of the planned initial public offering of Euronext, currently expected to occur in the second quarter of 2014, subject to certain regulatory approvals and other conditions.
	In January 2014, the Company formalized its plans to divest NYSE Technologies' two remaining business lines, Trading Solutions and Transaction Services, or “the NYSE Technologies divestiture group”. The Company is actively marketing the sale of these businesses, the NYSE Technologies divestiture group is available for immediate sale in its present condition, and the divestiture is expected to be completed this summer. The NYSE Technologies divestiture group primarily consists of the NYFIX, Wombat and Metabit technologies. NYFIX is a provider of FIX-based electronic trading technologies and includes the FIX Marketplace and Appia Business Suite. Wombat is a market data distribution platform, developing technology and supporting services for direct access to real-time global market data. Metabit is a Tokyo-based technology service offering proprietary market access products across Asia.
	The Company has reflected the results of the NYSE Technologies divestiture group as discontinued operations in the accompanying consolidated statement of income and consolidated statement of cash flows for the three months ended March 31, 2014. No comparable data for the prior year period is presented as the Company did not complete the acquisition of NYSE Euronext until November 2013. The results below include external advisory costs related to the planned sale of the divestiture group of $5 million. None of the Company’s interest expense has been allocated to the results of the NYSE Technologies divestiture group. The NYSE Technologies divestiture group is included in the ICE segment. Results of discontinued operations were as follows for the three months ended March 31, 2014 related to the NYSE Technologies divestiture group (in millions):
	Total revenues, less transaction-based expenses	$	27
	Total operating expenses and other expense, net	26
	Income before income tax expense	1
	Income tax benefit	1
	Income from discontinued operations, net of tax	$	2
	The following table presents the carrying value of the assets and liabilities of the NYSE Technologies divestiture group, which was reflected as $300 million in prepaid expenses and other current assets and $75 million in other current liabilities, in the accompanying consolidated balance sheet as of March 31, 2014 (in millions):
	Assets:
	Customer accounts receivable, net	$	21

	In connection with the Company's acquisition of NYSE Euronext in November 2013, ICE Group, IntercontinentalExchange, Inc. and NYSE Euronext established various guarantees to protect against structural subordination of each entities’ existing indebtedness. Each of IntercontinentalExchange, Inc. and NYSE Euronext are wholly owned subsidiaries of ICE Group, and each fully and unconditionally guaranteed, on an unsecured and unsubordinated basis, the payment of principal, premium, if any, and interest of ICE Group’s Senior Notes and, following its establishment, the Commercial Paper Program. Similarly, ICE Group and IntercontinentalExchange, Inc. each fully and unconditionally guaranteed, on an unsecured and unsubordinated basis, the payment of principal, premium, if any, and interest of the NYSE Euronext Notes. Finally, ICE Group and NYSE Euronext each fully and unconditionally guaranteed, on an unsecured and unsubordinated basis, the payment of principal, premium, if any, and interest of the 2011 Credit Facilities and the 364 Day Facility. All of the guarantees are joint and several with all other guarantees and indebtedness. ICE Group’s guarantees, as a standalone entity, will remain in place until each applicable debt obligation has been satisfied.
	As discussed in Note 6, the Company entered into the 2014 Credit Facility and terminated the 2011 Credit Facilities and the 364 Day Facility on April 3, 2014. Upon the termination of the 2011 Credit Facilities and the 364 Day Facility, IntercontinentalExchange, Inc.'s guarantees were no longer required and therefore IntercontinentalExchange, Inc.'s guarantees were automatically released in accordance with their terms on April 3, 2014. In connection with the Company's entry into the 2014 Credit Facility, NYSE Euronext agreed to guarantee the 2014 Credit Facility as a subsidiary guarantor.
	For as long as NYSE Euronext remains a guarantor of the 2014 Credit Facility, it will remain a guarantor of the Senior Notes and the Commercial Paper Program. The Company expects that NYSE Euronext’s guarantee of the 2014 Credit Facility, the Senior Notes and the Commercial Paper Program will be released when the NYSE Euronext Notes have been repaid, as the 2014 Credit Facility provides that NYSE Euronext’s guarantee will be released in accordance with their terms if certain conditions are satisfied, including compliance with the covenant limiting the amount of indebtedness of non-obligor subsidiaries and an investment-grade credit rating.
	The following consolidating financial information sets forth, under the equity method of accounting, the condensed consolidating statements of income and comprehensive income, the condensed consolidating balance sheets, and the condensed consolidating statements of cash flows for (i) ICE Group; (ii) IntercontinentalExchange, Inc.; (iii) NYSE Euronext; (iv) the subsidiary non-guarantors; (v) elimination entries necessary to consolidate each of ICE Group, IntercontinentalExchange, Inc. and NYSE Euronext with the non-guarantor subsidiaries; and (vi) the Company on a consolidated basis. As discussed in Note 1, the Company was formed on March 6, 2013 for purposes of effecting the acquisition of NYSE Euronext. Therefore, the condensed consolidating statements for periods prior thereto reflect how these statements would have been presented had the Company been established for all periods presented. The condensed consolidating financial statements only include activity related to NYSE Euronext for the period subsequent to November 13, 2013, the closing date of the acquisition, for the condensed consolidating statements of income, comprehensive income and cash flows, and as of March 31, 2014 and December 31, 2013 for the condensed consolidating balance sheets. The condensed consolidating financial information should be read in conjunction with the accompanying consolidated financial statements.

Geographical Information	'
	Segment Reporting
	The Company previously operated as a single reportable business segment as of December 31, 2013. As of March 31, 2014, the Company is reporting two business segments, the ICE segment and the Euronext segment, which is reflective of how the Company's chief operating decision maker reviews and operates the business. The Euronext segment comprises the European-based exchanges that includes Euronext N.V. - the London, Paris, Amsterdam, Brussels and Lisbon exchanges that include listings, cash and derivatives markets, market data and technology services. The businesses and operations reflected in these results are expected to be sold as part of the initial public offering of Euronext in the second quarter of 2014, subject to certain regulatory approvals and other conditions. All the remaining operations of the Company comprise the ICE segment. One business segment was reported for the three months ended March 31, 2013, as NYSE Euronext was acquired on November 13, 2013. The Company’s chief operating decision maker does not review total assets or intersegment revenues by segment, therefore, such information is not presented below. Financial data for the Company’s business segments are as follows for the three months ended March 31, 2014 (in millions):
		ICE Segment		Euronext Segment		Total
	Total revenues, less transaction-based expenses	$	796	$	136	$	932
	Total operating expenses	442		81		523
	Operating income	354		55		409
	Net income	239		36		275
	No customers or clearing members accounted for more than 10% of the Company’s segment revenues or consolidated revenues, less transaction-based expenses, for the three months ended March 31, 2014, and 2013.

	The following is a reconciliation of the numerators and denominators of the basic and diluted earnings per common share computations for the three months ended March 31, 2014 and 2013 (in millions, except per share amounts):
		Three Months Ended March 31,

	Discontinued operations	0.01			—
	Diluted earnings per share	$	2.27		$	1.85
	Diluted weighted average common shares outstanding	116			73
	Basic weighted average common shares outstanding	115			73
	Effect of dilutive securities - stock options and restricted stock	1			—
	Diluted weighted average common shares outstanding	116			73
	Basic earnings per common share is calculated using the weighted average common shares outstanding during the period. The weighted average common shares outstanding during the three months ended March 31, 2014 increased from the prior period primarily due to the 42.4 million shares of the Company's common stock issued to NYSE Euronext stockholders in connection with the acquisition as of November 13, 2013. Common equivalent shares from stock options and restricted stock awards, using the treasury stock method, are also included in the diluted per share calculations unless the effect of their inclusion would be antidilutive. During the three months ended March 31, 2014 and 2013, 116,000 and 196,000 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 because the outstanding stock option exercise prices were greater than the average market price of the common shares during the relevant period.

	Basis of Presentation
	The accompanying unaudited consolidated financial statements have been prepared by the Company in accordance with United States (“U.S.”) generally accepted accounting principles (“U.S. GAAP”) pursuant to the rules and regulations of the Securities and Exchange Commission regarding interim financial reporting. Accordingly, the unaudited consolidated financial statements do not include all of the information and footnotes required by U.S. GAAP for complete financial statements and should be read in conjunction with the Company’s audited consolidated financial statements and related notes thereto for the year ended December 31, 2013. The accompanying unaudited consolidated financial statements reflect all adjustments that are, in the opinion of the Company’s management, necessary for a fair presentation of results for the interim periods presented. These adjustments are of a normal recurring nature.
	Preparing financial statements requires management to make estimates and assumptions that affect the amounts that are reported in the consolidated financial statements and accompanying disclosures. Although these estimates are based on management’s best knowledge of current events and actions that the Company may undertake in the future, actual results may be different from these estimates. The results of operations for the three months ended March 31, 2014 are not necessarily indicative of the results to be expected for any future period or the full fiscal year.
	The accompanying unaudited consolidated financial statements include the accounts of the Company and its wholly-owned and controlled subsidiaries. All intercompany balances and transactions between the Company and its wholly-owned and controlled subsidiaries have been eliminated in consolidation. As discussed in Note 3, the Company completed an acquisition during the three months ended March 31, 2014 and has included the financial results of this company in its consolidated financial statements effective from the acquisition date.
	For those consolidated subsidiaries in which the Company’s ownership is less than 100% and for which the Company has control over the assets and liabilities and the management of the entity, the outside stockholders’ interests are shown as non-controlling interests.
