Forward-Looking Statements

From time to time, in this Quarterly Report on Form 10-Q as well as in other written reports and verbal statements, we discuss our expectations regarding future performance. These forward-looking statements are identified by their use of terms and phrases such as “believe,” “anticipate,” “could,” “estimate,” “intend,” “may,” “plan,” “expect” and similar expressions, including references to assumptions. These forward-looking statements are based on currently available competitive, financial and economic data, current expectations, estimates, forecasts and projections about the industries in which we operate and management's beliefs and assumptions. These statements are not guarantees of future performance and involve risks, uncertainties and assumptions that are difficult to predict. Therefore, actual outcomes and results may differ materially from what is expressed or implied in any forward-looking statements. We want to caution you not to place undue reliance on any forward-looking statements. We undertake no obligation to publicly update any forward-looking statements, whether as a result of new information, future events or otherwise. Among the factors that might affect our performance are:

• increasing competition by foreign and domestic entities, including increased competition from new entrants into our markets and consolidation of existing entities;

• our ability to keep pace with rapid technological developments, including our ability to complete the development, implementation and maintenance of the enhanced functionality required by our customers while maintaining reliability and ensuring that such technology is not vulnerable to security risks;

• our ability to continue introducing competitive new products and services on a timely, cost-effective basis, including through our electronic trading capabilities, and our ability to maintain the competitiveness of our existing products and services, including our ability to provide effective services to the swaps market;

• our ability to adjust our fixed costs and expenses if our revenues decline;

• our ability to maintain existing customers, develop strategic relationships and attract new customers;

• our ability to expand and offer our products outside the United States;

• changes in domestic and non-U.S. regulations, including the impact of any changes in domestic and foreign laws or government policy with respect to our industry, such as any changes to regulations and policies that require increased financial and operational resources from us or our customers;

• the costs associated with protecting our intellectual property rights and our ability to operate our business without violating the intellectual property rights of others;

• decreases in revenue from our market data as a result of decreased demand;

3

• changes in our rate per contract due to shifts in the mix of the products traded, the trading venue and the mix of customers (whether the customer receives member or non-member fees or participates in one of our various incentive programs) and the impact of our tiered pricing structure;

• the ability of our financial safeguards package to adequately protect us from the credit risks of clearing members;

• the ability of our compliance and risk management methods to effectively monitor and manage our risks, including our ability to prevent errors and misconduct and protect our infrastructure against security breaches and misappropriation of our intellectual property assets;

• changes in price levels and volatility in the derivatives markets and in underlying equity, foreign exchange, interest rate and commodities markets;

• economic, political and market conditions, including the volatility of the capital and credit markets and the impact of economic conditions on the trading activity of our current and potential customers;

• our ability to accommodate increases in contract volume and order transaction traffic and to implement enhancements without failure or degradation of the performance of our trading and clearing systems;

• our ability to execute our growth strategy and maintain our growth effectively;

• our ability to manage the risks and control the costs associated with our strategy for acquisitions, investments and alliances;

• our ability to continue to generate funds and/or manage our indebtedness to allow us to continue to invest in our business;

• industry and customer consolidation;

• decreases in trading and clearing activity;

• the imposition of a transaction tax or user fee on futures and options on futures transactions and/or repeal of the 60/40 tax treatment of such transactions;

• the unfavorable resolution of material legal proceedings; and

• the seasonality of the futures business.

For a detailed discussion of these and other factors that might affect our performance, see Item 1A. of our Annual Report on Form 10-K, filed with the Securities and Exchange Commission on February 28, 2014 and Item 1A. of this Quarterly Report on Form 10-Q.

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

1. Basis of Presentation

The consolidated financial statements consist of CME Group Inc. (CME Group) and its subsidiaries (collectively, the company), including Chicago Mercantile Exchange Inc. (CME), Board of Trade of the City of Chicago, Inc. (CBOT), New York Mercantile Exchange, Inc. (NYMEX), Commodity Exchange, Inc. (COMEX), and their respective subsidiaries (collectively, the exchange). The consolidated statements also include CME Clearing Europe Limited (CMECE).

The accompanying interim consolidated financial statements have been prepared by CME Group without audit. Certain notes and other information normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States have been condensed or omitted. In the opinion of management, the accompanying consolidated financial statements include all normal recurring adjustments considered necessary to present fairly the financial position of the company at March 31, 2014 and December 31, 2013 and the results of operations and cash flows for the periods indicated. Quarterly results are not necessarily indicative of results for any subsequent period.

The accompanying consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto in CME Group’s Annual Report on Form 10-K for the year ended December 31, 2013, filed with the Securities and Exchange Commission (SEC) on February 28, 2014.

2. Performance Bonds and Guaranty Fund Contributions

Performance Bonds and Guaranty Fund Contributions. At March 31, 2014, performance bonds and guaranty fund contributions in the consolidated balance sheet included performance bond and guaranty fund contributions received in the form of cash that were reinvested by CME in U.S. Treasury securities with maturity dates of 30 days or less. Any interest earned on these U.S. Treasury investments accrues to CME and is included in the consolidated statements of income. Because CME has control of the cash collateral reinvested in U.S. Treasury securities and the benefits and risks of ownership accrue to CME, these performance bonds and guaranty fund contributions are reflected in the consolidated balance sheets. The amortized cost and fair value of the U.S. Treasury securities were both $2.9 billion as of March 31, 2014. The U.S. Treasury securities matured on April 3, 2014. The U.S. Treasury securities are considered a level 1 asset under the classification hierarchy for fair value measurements because the securities are valued using a quoted price in an active market.

Clearing House Contract Settlement. CME and CME Clearing Europe Limited (CMECE) mark-to-market open positions for all products at least once a day (twice a day for futures and options contracts). Based on values derived from the mark-to-market process, CME and CMECE require payment from clearing firms whose positions have lost value and make payments to clearing firms whose positions have gained value. Under the extremely unlikely scenario of simultaneous default by every clearing firm who has open positions with unrealized losses, the maximum exposure related to positions other than over-the-counter credit default and interest rate swap contracts would be one half day of changes in fair value of all open positions, before considering the clearing houses' ability to access defaulting clearing firms' collateral deposits. For CME's cleared over-the-counter credit default swap and interest rate swap contracts, the maximum exposure related to CME's guarantee would be one full day of changes in fair value of all open positions, before considering CME's ability to access defaulting clearing firms' collateral. During the first quarter of 2014, the clearing houses transferred an average of approximately $2.8 billion a day through their clearing systems for settlement from clearing firms whose positions had lost value to clearing firms whose positions had gained value. The clearing houses reduce the guarantee exposure through initial and maintenance performance bond requirements and mandatory guaranty fund contributions. The company believes that the guarantee liability is immaterial and therefore has not recorded any liability at March 31, 2014.

3. Intangible Assets

Intangible assets consisted of the following at March 31, 2014 and December 31, 2013:

Clearing and transaction fees revenues are generated through the trading of these products. These trading products, most of which have traded for decades, require authorization from the CFTC. Product authorizations from the CFTC have no term limits.

Total amortization expense for intangible assets was $25.2 million and $25.9 million for the quarters ended March 31, 2014 and 2013, respectively. As of March 31, 2014, the future estimated amortization expense related to amortizable intangible assets is expected to be as follows:

(in millions)	Amortization Expense
Remainder of 2014	$	75.6
2015	100.6
2016	97.2
2017	96.4

(in millions)	March 31, 2014		December 31, 2013
$750.0 million fixed rate notes due February 2014, stated rate of 5.75%	$	—	$	749.9
Total short-term debt	$	—	$	749.9

Long-term debt consisted of the following at March 31, 2014 and December 31, 2013:

(in millions)	March 31, 2014		December 31, 2013
$612.5 million fixed rate notes due March 2018, stated rate of 4.40%(1)	$	610.7	$	610.5
$750.0 million fixed rate notes due September 2022, stated rate of 3.00% (2)	748.0		748.0

Total long-term debt	$	2,107.4	$	2,107.2

(1) In February 2010, CME Group entered into a forward-starting interest rate swap agreement that modified the interest obligation associated with these notes so that the interest payable on the notes effectively became fixed at a rate of 4.46%.

(2) In August 2012, CME Group entered into a forward-starting interest rate swap agreement that modified the interest obligation associated with these notes so that the interest payable on the notes effectively became fixed at a rate of 3.32%.

(3) In August 2012, CME Group entered into a forward-starting interest rate swap agreement that modified the interest obligation associated with these notes so that the interest payable on the notes effectively became fixed at a rate of 4.73%.

Long-term debt maturities, at par value, were as follows as of March 31, 2014:

(in millions)	Par Value
2015	$	—
2016	—
2017	—
2018	612.5
2019	—
Thereafter	1,500.0

The fair value of the fixed rate notes due 2018, which is considered a level 3 liability under the classification hierarchy for fair value measurements, was derived using a standard valuation model with market-based observable inputs including U.S. Treasury yields and interest rate spreads. The fair values of the fixed rate notes due 2022 and 2043 were estimated using quoted market prices and are considered level 2 liabilities. For further information on the three-level classification hierarchy of fair value measurements, see note 8. At March 31, 2014, the fair values of the fixed rate notes by maturity date were as follows:

(in millions)	Fair Value
$612.5 million fixed rate notes due March 2018, stated rate of 4.40%	$	664.0
$750.0 million fixed rate notes due September 2022, stated rate of 3.00%	742.1
$750.0 million fixed rates notes due September 2043, stated rate of 5.30%	842.2

5. Contingencies

Legal and Regulatory Matters. In 2008, Fifth Market, Inc. (Fifth Market) filed a complaint against CME Group and CME in the Delaware District Court seeking a permanent injunction against CME's Globex system and unquantified enhanced damages for what the plaintiff alleges is willful infringement of two patents, in addition to costs, expenses and attorneys' fees. The case was stayed pending the outcome of CME's request for reexamination by the U.S. Patent and Trademark Office (USPTO). The reexaminations resulted in some claims being rejected and others being confirmed. In June 2013, the court lifted the stay. The validity of the patents, however, remains subject to further review by the USPTO. Based on its investigation to date and advice from legal counsel, the company believes this suit is without merit and intends to defend itself vigorously against these charges.

13

In 2009, CME and CBOT filed a complaint against Howard Garber in the Northern District of Illinois seeking a declaratory judgment that neither CME nor CBOT infringed the Garber patent, which relates to electronic market makers, and that the patent is invalid and unenforceable. The Technology Research Group (TRG) was substituted for Mr. Garber in 2009 and TRG filed counterclaims alleging patent infringement and other related claims. In 2011, the case was dismissed with the right to reinstate pending the outcome of a reexamination by the USPTO. In August and October 2013, the USPTO issued actions resulting in the rejection of all TRG’s claims completing the reexamination process. In January 2014, TRG appealed the decision of the USPTO. Based on its investigation to date and advice from legal counsel, the company believes this suit is without merit and intends to defend itself vigorously against these charges.

The foregoing legal matters involve alleged infringements of intellectual property which, due to their nature, involve potential liability that is uncertain, difficult to quantify and involves a wide range of potential outcomes. The company believes that the matters are without merit, and the company intends to defend itself vigorously against the claims. We expect the re-examinations by the USPTO in the Fifth Market and Garber matters, including any appeals thereof, to result in a determination of the validity of the patents at issue which we expect will have an impact on the merits of the matters. Given the uncertainty of factors which may potentially impact the resolution of these matters, at this time the company is unable to estimate the reasonably possible loss or range of reasonably possible loss in the unlikely event it were found to be liable at trial in these matters.

A number of lawsuits were filed in federal court in New York on behalf of all commodity account holders or customers of MF Global who had not received a return of 100% of their funds. These matters have been consolidated into a single action in federal court in New York, and a consolidated amended class action complaint was filed on November 5, 2012. On November 6, 2013, CME announced that it has reached an agreement in principle to resolve the class action litigation. In an agreement between the trustee and CME, CME will be allowed to assert a $29.0 million claim against MF Global based on expenses incurred by CME as a result of MF Global’s bankruptcy. In a separate agreement between CME and the customer representatives, CME has agreed to deliver $14.5 million, one-half of the distribution that it will receive from the trustee, to the customer representatives for distribution to MF Global’s former customers. In connection with the settlements between the company and the trustee and the customers, the company’s $550.0 million financial guarantee to the bankruptcy trustee to cover any shortfall in the bankruptcy will be extinguished. The company believes that the likelihood of payment to the trustee is very remote. As a result, the guarantee liability is estimated to be immaterial at March 31, 2014.

In February 2013, the CFTC filed suit against NYMEX and two former employees alleging disclosure of confidential customer information in violation of the Commodity Exchange Act. Based on the initial review of the complaint, the company believes that it has strong factual and legal defenses to the claim.

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

In addition, the company is a defendant in, and has potential for, various other legal proceedings arising from its regular business activities. While the ultimate results of such proceedings against the company cannot be predicted with certainty, the company believes that the resolution of any of these matters on an individual basis will not have a material impact on its consolidated financial position or results of operations.

At March 31, 2014 and December 31, 2013, the company had accrued $4.3 million and $11.3 million, respectively, for legal and regulatory matters that were probable and estimable.

Intellectual Property Indemnifications. Certain agreements with customers and other third parties related to accessing the CME platforms; utilizing market data services; and licensing CME SPAN software may contain indemnifications from intellectual property claims that may be made against them as a result of their use of the applicable products and/or services. The potential future claims relating to these indemnifications cannot be estimated and therefore no liability has been recorded.

6. Guarantees

Mutual Offset Agreement. CME and Singapore Exchange Limited (SGX) have a mutual offset agreement with a current term through October 2014. This agreement enables market participants to open a futures position on one exchange and liquidate it on the other. The term of the agreement will automatically renew for a one-year period unless either party provides advance notice of their intent to terminate. CME can maintain collateral in the form of U.S. Treasury securities or irrevocable, standby letters of credit. At March 31, 2014, CME was contingently liable to SGX on letters of credit totaling $460.0 million. Regardless of the collateral, CME guarantees all cleared transactions submitted through SGX and would initiate procedures designed to satisfy these financial obligations in the event of a default, such as the use of performance bonds and guaranty fund contributions of the defaulting clearing firm. The company believes that its guarantee liability is immaterial and therefore has not recorded any liability at March 31, 2014.

14

Family Farmer and Rancher Protection Fund. In April 2012, the company established the Family Farmer and Rancher Protection Fund (the Fund). The Fund is designed to provide payments, up to certain maximum levels, to family farmers, ranchers and other agricultural industry participants who use the company's agricultural products and who suffer losses to their segregated account balances due to their CME clearing member becoming insolvent. Under the terms of the Fund, farmers and ranchers are eligible for up to $25,000 per participant. Farming and ranching cooperatives are eligible for up to $100,000 per cooperative. The Fund was established with a maximum payment amount of $100.0 million. Since its establishment, the Fund has made payments of approximately $2.0 million, which leaves $98.0 million available for future claims. If payments to participants were to exceed the amount remaining in the fund at the time of insolvency, payments would be pro-rated. Clearing members and customers must register in advance with the company and provide certain documentation in order to substantiate their eligibility. The company believes that its guarantee liability is immaterial and therefore has not recorded any liability at March 31, 2014.

7. Accumulated Other Comprehensive Income

The following tables present changes in the accumulated balances for each component of other comprehensive income attributable to CME Group, including current period other comprehensive income and reclassifications out of accumulated other comprehensive income:

8. Fair Value Measurements

The company uses a three-level classification hierarchy of fair value measurements for disclosure purposes.

• Level 1 inputs, which are considered the most reliable evidence of fair value, consist of quoted prices (unadjusted) for identical assets or liabilities in active markets.

• Level 2 inputs consist of observable market data, 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 consist of unobservable inputs which are derived and cannot be corroborated by market data or other entity-specific inputs.

Level 1 assets generally include U.S. Treasury securities and investments in publicly traded stocks and mutual funds with quoted market prices. In general, the company uses quoted prices in active markets for identical assets to determine the fair

15

value of marketable securities and equity investments. If quoted prices are not available to determine fair value, the company uses other inputs that are directly observable.

Assets included in level 2 generally consist of asset-backed securities. Asset-backed securities were measured at fair value based on matrix pricing using prices of similar securities with similar inputs such as maturity dates, interest rates and credit ratings.

The company determined the fair value of its contingent consideration liabilities, considered level 3 liabilities, using a discounted cash flow model to calculate the present value of future payouts. The liabilities were included in level 3 because management used significant unobservable inputs, including a discount rate of 20% and payout probabilities of either 75% or 100%. Significant increases or decreases in any of those inputs in isolation would result in a significantly different fair value.

Financial assets and liabilities recorded in the consolidated balance sheet as of March 31, 2014 were classified in their entirety based on the lowest level of input that was significant to each asset or liability's fair value measurement. The following presents financial instruments measured at fair value on a recurring basis:

	March 31, 2014
(in millions)	Level 1		Level 2		Level 3		Total
Assets at Fair Value:
Marketable securities:
U.S. Treasury securities	$	19.2	$	—	$	—	$	19.2
Mutual funds	52.6		—		—		52.6
Asset-backed securities	—		0.4		—		0.4
Total Marketable Securities	71.8		0.4		—		72.2
Equity investments	524.9		—		—		524.9
Total Assets at Fair Value	$	596.7	$	0.4	$	—	$	597.1
Liabilities at Fair Value:
Contingent consideration	$	—	$	—	$	19.2	$	19.2
Total Liabilities at Fair Value	$	—	$	—	$	19.2	$	19.2

There were no transfers of assets or liabilities between level 1 and level 2 during the first quarter of 2014. The following is a reconciliation of liabilities valued at fair value on a recurring basis using significant unobservable inputs (level 3) during the first quarter of 2014. There were no assets valued at fair value on a recurring basis using significant unobservable inputs (level 3) during the first quarter of 2014.

(in millions)	Contingent Consideration
Fair value of liability at December 31, 2013	$	15.7
Realized and unrealized (gains) losses:
Included in other expenses	3.5
Fair value of liability at March 31, 2014	$	19.2

There were no assets or liabilities valued at fair value on a nonrecurring basis using significant unobservable inputs (level 3) during the first quarter of 2014.

9. Earnings Per Share

Basic earnings per share is computed by dividing net income attributable to the company by the weighted average number of shares of all classes of CME Group common stock outstanding for each reporting period. Diluted earnings per share reflects the increase in shares using the treasury stock method to reflect the impact of an equivalent number of shares of common stock if stock options were exercised and restricted stock awards were converted into common stock. Anti-dilutive stock options and restricted stock awards were as follows for the periods presented:

	Quarter Ended March 31,
(in thousands)	2014	2013
Stock options	1,498	1,734
Stock awards	4	41
Total	1,502	1,775

The following table presents the earnings per share calculation for the periods presented:

	Quarter Ended March 31,
	2014		2013
Net Income Attributable to CME Group (in millions)	$	266.8	$	235.8
Weighted Average Number of Common Shares (in thousands):
Basic	333,905		331,953
Effect of stock options and restricted stock awards	1,739		1,419

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion is provided as a supplement to, and should be read in conjunction with, the accompanying unaudited consolidated financial statements and notes in this Quarterly Report on Form 10-Q and in our Annual Report on Form 10-K for the year ended December 31, 2013.

References in this discussion and analysis to “we,” “us” and “our” are to CME Group Inc. (CME Group) and its consolidated subsidiaries, collectively. References to “exchange” are to Chicago Mercantile Exchange Inc. (CME), Board of Trade of the City of Chicago, Inc. (CBOT), New York Mercantile Exchange, Inc. (NYMEX), and Commodity Exchange, Inc. (COMEX), collectively, unless otherwise noted. CME Group also includes CME Clearing Europe Limited. CME also serves as a swap execution facility, which is a regulated platform for swap trading, and serves as a swap data repository, which provides public data on swap transactions and stores confidential swap data for regulatory purposes.

RESULTS OF OPERATIONS

Financial Highlights

The following summarizes significant changes in our financial performance for the periods presented.

	Quarter Ended March 31,
(dollars in millions, except per share data)	2014			2013			Change
Total revenues	$	777.4		$	718.6		8	%
Total expenses	322.9			313.1			3
Operating margin	58.5		%	56.4		%
Non-operating income (expense)	$	(8.1	)	$	(17.9	)	(55	)

Net income attributable to CME Group	$	266.8		$	235.8		13
Diluted earnings per common share attributable to CME Group	0.79			0.71			11
Cash flows from operating activities	383.0			396.0			(3	)

n.m. not meaningful

• In the first quarter of 2014 when compared with the same period in 2013, the increase in revenues was attributable to higher contract volume in exchange-traded and over-the-counter products and an increase in market data fees related to an increase in fees for basic real-time market data service. The increase was also due to a fee increase related to clearing and transaction fees, partially offset by a decrease in rate per contract due to a shift in the relative mix of product volume.

• Operating expenses increased slightly in the first quarter of 2014 when compared with the same period in 2013 due to an increase in licensing fees related to higher volume and an increase in expense related to the development and continued enhancement of our product offerings and our electronic platforms, partially offset by a change in net losses (gains) on foreign currency fluctuations. In the first quarter of 2014, we recognized a net gain on foreign currency fluctuations and in the first quarter of 2013, we recognized a net loss on foreign currency fluctuations.

• The decrease in non-operating income (expense) in the first quarter of 2014 when compared with the same period in 2013 was due to an increase in income generated from S&P/Dow Jones Indices LLC (S&P/DJI) as well as a decrease in interest expense due to the repayment of the 5.75% fixed rate notes due February 2014, the repayment of the 5.4% fixed rate notes due August 2013 and the issuance of the 5.3% fixed rate notes due September 2043 that were effectively fixed at a rate of 4.73% through an interest rate swap agreement.

• The increase in the effective tax rate in the first quarter of 2014 when compared with the same period in 2013 was attributable to changes in future state apportionment factors resulting from state law changes, partially offset by a decrease resulting from state audit activity in the first quarter of 2014.

Revenues

	Quarter Ended March 31,
(dollars in millions)	2014		2013		Change
Clearing and transaction fees	$	652.2	$	593.2	10	%
Market data and information services	89.4		80.9		11
Access and communication fees	20.4		21.5		(5	)
Other	15.4		23.0		(33	)
Total Revenues	$	777.4	$	718.6	8

Clearing and Transaction Fees

The following table summarizes our total contract volume, revenue and average rate per contract. Total contract volume includes contracts that are traded on our exchange and cleared through our clearing house as well as cleared-only contracts. Volume is measured in round turns, which is considered a completed transaction that involves a purchase and an offsetting sale of a contract. Average rate per contract is determined by dividing total clearing and transaction fees by total contract volume. Volume and average rate per contract disclosures exclude our CME interest rate swap, CME credit default swap and CME Clearing Europe contracts.

	Quarter Ended March 31,
	2014		2013		Change
Total contract volume (in millions)	833.2		750.5		11	%
Clearing and transaction fees (in millions)	$	639.3	$	590.0	8
Average rate per contract	$	0.767	$	0.786	(2	)

We estimate the following increases (decreases) in clearing and transaction fees based on change in total contract volume and change in average rate per contract during the first quarter of 2014 when compared with the same period in 2013.

(in millions)	Quarter Ended
Increase due to change in total contract volume	$	63.4
Decrease due to change in average rate per contract	(14.1		)
Increase in clearing and transaction fees	$	49.3

Average rate per contract is impacted by our rate structure, including volume-based incentives; product mix; trading venue, and the percentage of volume executed by customers who are members compared with non-member customers. Due to the relationship between average rate per contract and contract volume, the change in clearing and transaction fees attributable to the change in each is only an approximation.

Clearing and transaction fees as presented in the consolidated statements of income include revenues for our cleared-only CME interest rate swap and CME credit default swap contracts. In the first quarter of 2014 when compared with the same period in 2013, clearing and transaction fees generated from these contracts increased by $9.7 million. The increase in revenue was largely attributable to an increase in CME interest rate swap contract volume resulting from the over-the-counter clearing mandate required to be implemented starting in mid-2013 by the Dodd-Frank Wall Street Reform and Consumer Protection Act.

Contract Volume

The following table summarizes average daily contract volume. Contract volume can be influenced by many factors, including political and economic conditions, the regulatory environment and market competition. 

	Quarter Ended March 31,
(amounts in thousands)	2014	2013	Change
Average Daily Volume by Product Line:
Interest rate	6,724	5,656	19	%
Equity	2,890	2,608	11
Foreign exchange	817	1,010	(19	)
Agricultural commodity	1,168	1,108	5
Energy	1,705	1,730	(1	)
Metal	355	397	(11	)
Aggregate average daily volume	13,659	12,509	9
Average Daily Volume by Venue:
Electronic	11,703	10,932	7
Open outcry	1,179	886	33
Privately negotiated (1)	777	691	13
Aggregate average daily volume	13,659	12,509	9

(1) Privately negotiated venue average daily volume includes both traditional block trades as well as what was historically categorized as CME ClearPort.

Interest Rate Products

The following table summarizes average daily contract volume for our key interest rate products. Eurodollar Front 8 futures include contracts expiring in two years or less. Eurodollar Back 32 futures include contracts with expirations after two years through ten years.

	Quarter Ended March 31,
(amounts in thousands)	2014	2013	Change
Eurodollar futures and options:
Front 8 futures	1,432	1,097	31	%
Back 32 futures	1,045	734	42
Options	822	400	106
U.S. Treasury futures and options:
10-Year	1,714	1,693	1
5-Year	873	811	8
Treasury bond	398	508	(22	)
2-Year	255	267	(4	)

Overall interest rate volume increased in the first quarter of 2014 when compared with the same period in 2013 largely due to an increase in Eurodollar futures and options contract volume resulting from a change in market expectations regarding interest rates caused by improved domestic macroeconomic data regarding unemployment. Short-term Eurodollar contract volume in the first quarter of 2013 was negatively impacted by the Federal Reserve's ongoing zero interest rate policy.

U.S. Treasury futures and options volume remained flat overall in the first quarter of 2014 when compared with the same period in 2013. An increase in volume for short-term U.S. Treasury contracts due to a change in market expectations regarding an increase in interest rates in the first quarter of 2014 was offset by higher U.S. Treasury contract volume in the first quarter of 2013 resulting from the Federal Reserve's intention to revisit their quantitative easing strategy and outline a quantitative easing exit strategy in early 2013.

20

Equity Products

The following table summarizes average daily contract volume for our key equity products.

	Quarter Ended March 31,
(amounts in thousands)	2014	2013	Change
E-mini S&P 500 futures and options	2,251	2,115	6	%
E-mini NASDAQ 100 futures and options	315	231	36

Overall equity contract volume increased in the first quarter of 2014 when compared with the same period in 2013 due to periods of higher volatility, as measured by the CBOE Volatility Index and CBOE Nasdaq-100 Volatility Index, in early 2014. We believe the higher volatility was caused by geopolitical events and changes in market expectations regarding macroeconomic data. We experienced higher E-mini S&P 500 contract volume in the first quarter of 2013 due to short periods of high volatility related to the Eurozone crisis in early 2013.

Foreign Exchange Products

The following table summarizes average daily contract volume for our key foreign exchange products.

	Quarter Ended March 31,
(amounts in thousands)	2014	2013	Change
Euro	235	333	(29	)%
Japanese yen	167	213	(22	)
British pound	120	141	(15	)
Australian dollar	98	105	(7	)
Canadian dollar	74	83	(11	)

The overall decrease in foreign exchange contract volume in the first quarter of 2014 when compared with the same period in 2013 was attributable to a decrease in exchange rate volatility within European countries as well as Japan. Subdued expectations regarding interest rate changes across European countries and Japan led to the decrease in exchange rate volatility throughout these regions. Additionally, allegations regarding possible collusion by certain foreign exchange market participants in other marketplaces had a negative impact on overall global foreign exchange product trading during the first quarter of 2014.

Agricultural Commodity Products

The following table summarizes average daily contract volume for our key agricultural commodity products.

	Quarter Ended March 31,
(amounts in thousands)	2014	2013	Change
Corn	389	358	9	%
Soybean	254	244	4
Wheat	166	158	5
Soybean oil	104	105	(1	)

The overall increase in agricultural commodity contract volume in the first quarter of 2014 when compared with the same period in 2013 was due to volatility caused by an increase in grain supplies from 2013 to 2014 as well as higher price volatility in corn and wheat products due to political instability in the Black Sea region in the first quarter of 2014.

Energy Products

The following table summarizes average daily contract volume for our key energy products.

	Quarter Ended March 31,
(amounts in thousands)	2014	2013	Change
Crude oil	725	748	(3	)%
Natural gas	606	597	1
Refined products	294	330	(11	)

21

Overall energy contract volume remained relatively flat in the first quarter of 2014 when compared with the same period of 2013. The decline in refined products contract volume in the first quarter of 2014 when compared with the same period of 2013 was due to a decrease in demand in the underlying physical market. Crude oil product volume also decreased due to low price volatility in the first quarter of 2014 compared with the same period in 2013. The decreases in refined product volume and crude oil product volume was partially offset by an increase in natural gas contract volume in the first quarter of 2014 when compared with the same period in 2013, which was attributable to volatility caused by weather-related events.

Metal Products

The following table summarizes average daily volume for our key metal products.

	Quarter Ended March 31,
(amounts in thousands)	2014	2013	Change
Gold	209	247	(15	)%
Silver	64	60	7
Copper	61	65	(7	)

Overall metal product volume decreased in the first quarter of 2014 when compared with the same period of 2013 due to a decrease in gold contract volumes resulting from a decrease in price volatility. Volatility was higher in the first quarter of 2013 because of uncertainty surrounding the Federal Reserve's intention to withdraw from quantitative easing in early 2013.

Average Rate per Contract

The average rate per contract decreased in the first quarter of 2014 when compared with the same period in 2013 due to a shift in the relative mix of product volume. In the first quarter of 2014, interest rate product volume, when measured as a percentage of total volume, increased by 4%, while foreign exchange product volume decreased by 2% and energy product volume decreased by 1% when compared with the same period in 2013. Interest rate contracts have a lower average rate per contract compared with foreign exchange and energy products. In addition, the decrease in average rate per contract in the first quarter of 2014 when compared with 2013 resulted from an increase in incentives and discounts on our energy contracts as well as an an increase in tier discounts on Eurodollar products. The overall decrease in average rate per contract was partially offset by an increase due to transaction fee pricing changes that we implemented at the beginning of 2014.

Concentration of Revenue

We bill a substantial portion of our clearing and transaction fees directly to our clearing firms. The majority of clearing and transaction fees received from clearing firms represent charges for trades executed and cleared on behalf of their customers. One firm represented 11% of our clearing and transaction fees revenue in the first quarter of 2014. Should a clearing firm withdraw, we believe that the customer portion of the firm’s trading activity would likely transfer to another clearing firm of the exchange. Therefore, we do not believe we are exposed to significant risk from the ongoing loss of revenue received from or through a particular clearing firm.

Other Sources of Revenue

The increase in market data and information services revenue in the first quarter of 2014 when compared with the same period in 2013 was attributable to an increase in fees for basic real-time market data service to $85 per month in 2014 from $70 per month in 2013. The increase was partially offset by a decline in market data subscriber counts resulting from continued cost-cutting initiatives at customer firms as well as utilization of a legacy incentive program.

The two largest resellers of our market data represented approximately 44% of our market data and information services revenue in the first quarter of 2014. Despite this concentration, we consider exposure to significant risk of revenue loss to be minimal. In the event that one of these vendors no longer subscribes to our market data, we believe the majority of that vendor’s customers would likely subscribe to our market data through another reseller. Additionally, several of our largest institutional customers that utilize services from our two largest resellers report usage and remit payment of their fees directly to us.

In the first quarter of 2014 when compared with the same period in 2013, the decrease in other revenue was attributable to $8.7 million in fees recognized upon delivery of services under our technology agreement with BM&FBOVESPA S.A. in the first quarter of 2013. Also, in the fourth quarter of 2013, we sold the NYMEX building, which resulted in a decrease in rental income in the first quarter of 2014 when compared with the same period in 2013. The decrease in other revenues was partially offset by an increase in revenue generated from GFX Corporation due to an increase in trading volume.

Expenses

	Quarter Ended March 31,
(dollars in millions)	2014		2013		Change
Compensation and benefits	$	135.5	$	129.4	5	%
Communications	8.2		8.9		(8	)
Technology support services	13.9		12.4		13
Professional fees and outside services	29.6		21.9		35
Amortization of purchased intangibles	25.2		25.9		(3	)
Depreciation and amortization	34.1		32.6		5
Occupancy and building operations	23.2		18.5		25
Licensing and other fee agreements	29.0		21.2		37
Other	24.2		42.3		(43	)
Total Expenses	$	322.9	$	313.1	3

Operating expenses increased by $9.8 million in the first quarter of 2014 when compared with the same period in 2013. The following table shows the estimated impact of key factors resulting in the change in operating expenses:

	Quarter Ended, March 31, 2014
	Amount  of Change			Change as  a Percentage of Total Expenses
(dollars in millions)
Licensing and other fee agreements	$	7.8		2	%
Business enhancements and platform development	6.7			2
Salaries, benefits and employer taxes	6.3			2
Contingent consideration obligation	3.1			1
Bonus expense	2.9			1
Litigation accruals	(8.0		)	(2	)
Net losses (gains) on foreign currency fluctuation	(15.1		)	(5	)
Other expenses, net	6.1			2
Total increase	$	9.8		3	%

Operating expenses increased in the first quarter of 2014 when compared with the same period in 2013 due to an increase in licensing and other fee agreement expense resulting from higher volumes for interest rate swap products and certain equity contracts as well as higher fee rates on certain products.

Operating expense also increased due to higher professional fees and depreciation and amortization expense associated with the development and continued enhancement of our product offerings and our electronic platforms.

An increase in average headcount due to efforts to expand our product offerings and geographic reach as well as to meet additional regulatory requirements also contributed to an increase in compensation and benefits expense.

A fair value assessment of a contingent consideration obligation arising from an acquisition in 2010 resulted in an increase in expense in the first quarter of 2014 when compared with the same period in 2013.

Bonus expense increased due to an overall increase in average headcount and an increase in annual base salaries in the first quarter of 2014 when compared with the same period in 2013.

The increase in overall operating expenses in the first quarter of 2014 when compared with the same period in 2013 was partially offset by a reduction in a litigation accrual due to a favorable court ruling and a denial for a rehearing in the first quarter of 2014.

Additionally, the increase in overall operating expenses was partially offset by a change in net losses (gains) on foreign currency fluctuations. In the first quarter of 2014, we recognized a net gain on foreign currency fluctuations due to a favorable change in exchange rates on foreign cash balances. In the first quarter of 2013, we recognized a net loss on foreign currency fluctuations due to an unfavorable change in exchange rates on foreign cash balances. Gains and losses on foreign currency fluctuation result when subsidiaries with a U.S. dollar functional currency hold cash as well as certain other assets and

23

liabilities denominated in foreign currencies. We expect the foreign currency gain/loss to continue to fluctuate as long as this is the case.

Non-Operating Income (Expense)

	Quarter Ended March 31,
(dollars in millions)	2014			2013			Change
Investment income	$	3.2		$	3.6		(11	)%
Interest and other borrowing costs	(33.7		)	(39.0		)	(14	)
Equity in net gains (losses) of unconsolidated subsidiaries	22.4			17.5			28
Total Non-Operating	$	(8.1	)	$	(17.9	)	(55	)

The following table shows the key impacts in the overall decrease in interest expense and other borrowing costs in the first quarter of 2014 when compared with the same period in 2013:

	Quarter Ended March 31,
	2014			2013			Change
Weighted average borrowings outstanding (in millions)	$	2,487.5		$	2,862.5		$	(375.0	)
Weighted average effective yield	4.38		%	4.80		%	(0.42		)%
Average cost of borrowings (1)	4.54			4.98			(0.44		)

(1) Average cost of borrowings includes interest, the effective portion of interest rate hedges, discount accretion and debt issuance costs. Commitment fees on line of credit agreements are not included in the average cost of borrowing.

In the first quarter of 2014, we repaid the 5.75% fixed rate notes due February 2014. In the third quarter of 2013, we repaid $750.0 million of 5.4% fixed rate notes due August 2013 and issued $750.0 million of 5.3% fixed rate notes due September 2043. We entered into an interest rate swap agreement that resulted in an effective interest rate of 4.73% on the 5.3% fixed rate notes due September 2043. These factors contributed to a decrease in weighted average borrowings outstanding, weighted average effective yield and average cost of borrowings in the first quarter of 2014 when compared with the same period in 2013.

Interest and other borrowing costs also include commitment fees on our line of credit agreements. Commitment fees increased in the first quarter of 2014 when compared with the same period in 2013 due to higher fees associated with a $2.0 billion increase in our line of credit upon renewal in the fourth quarter of 2013.

An increase in income generated from our S&P/DJI business venture contributed to an increase in equity in net gains (losses) of unconsolidated subsidiaries in first quarter of 2014 when compared with the same period in 2013.

Income Tax Provision

The following table summarizes the effective tax rate for the periods presented:

	2014		2013		Change
Quarter Ended March 31	40.3	%	38.8	%	1.5	%

The increase in the effective tax rate in the first quarter of 2014 when compared with the same period in 2013 was attributable to changes in future state apportionment factors resulting from state law changes, partially offset by a decrease resulting from state audit activity in the first quarter of 2014.

Liquidity and Capital Resources

Sources and Uses of Cash. Net cash provided by operating activities in the first quarter of 2014 was relatively consistent with net cash provided by operating activities in the first quarter of 2013. Net cash used in investing activities increased in the first quarter of 2014 when compared with the same period of 2013 due to an increase in purchases of property and equipment due to ongoing efforts to consolidate some of our data centers. This increase in cash used was partially offset by proceeds from the sale of building property in the first quarter of 2014. Cash used in financing activities was higher in the first quarter of 2014 when compared with the same period in 2013. The increase in cash used was attributable to higher cash dividends in the first quarter of 2014 when compared with the same period in 2013. The annual variable dividend from 2013 operations was paid in the first quarter of 2014. The annual variable dividend from 2012 operations was paid in the fourth quarter of 2012 due to

24

uncertainty surrounding dividend income tax treatment beginning in 2013. The increase in cash used was also due to the repayment of the fixed rate notes due February 2014.

Debt Instruments. The following table summarizes our debt outstanding as of March 31, 2014:

(in millions)	Par Value
Fixed rate notes due March 2018, stated rate of 4.40% (1)	612.5
Fixed rate notes due September 2022, stated rate of 3.00% (2)	750.0
Fixed rate notes due September 2043, stated rate of 5.30% (3)	750.0

(1) In February 2010, we entered into a forward-starting interest rate swap agreement that modified the interest obligation associated with these notes so that the interest payable on the notes effectively became fixed at a rate of 4.46%.

(2) In August 2012, we entered into a forward-starting interest rate swap agreement that modified the interest obligation associated with these notes so that the interest payable effectively became fixed at a rate of 3.32%.

(3) In August 2012, we entered into a forward-starting interest rate swap agreement that modified the interest obligation associated with these notes so that the interest payable effectively became fixed at a rate of 4.73%.

We maintain a $1.8 billion multi-currency revolving senior credit facility with various financial institutions. The proceeds from the revolving senior credit facility can be used for general corporate purposes, which includes providing liquidity for our CME clearing house in certain circumstances at CME Group's discretion and, if necessary, for maturities of commercial paper. As long as we are not in default under the senior credit facility, we have the option to increase the facility up to $2.5 billion with the consent of the agent and lenders providing the additional funds. This senior credit facility matures in January 2016. The senior credit facility is voluntarily prepayable from time to time without premium or penalty. Under the credit facility, we are required to remain in compliance with a consolidated net worth test, which is defined as our consolidated shareholders' equity as of September 30, 2012, giving effect to share repurchases made and special dividends paid during the term of the agreements (and in no event greater than $2.0 billion in aggregate), multiplied by 0.65. We currently do not have any borrowings outstanding under the credit facility.

We maintain a 364-day multi-currency line of credit with a consortium of domestic and international banks to be used in certain situations by our CME clearing house. The line of credit provides for borrowings of up to $7.0 billion. We may use the proceeds to provide temporary liquidity in the unlikely event of a clearing firm default, in the event of a liquidity constraint or default by a depositary (custodian for our collateral), or in the event of a temporary disruption with the domestic payments system that would delay payment of settlement variation between us and our clearing firms. CME clearing firm guaranty fund contributions received in the form of cash, U.S. Treasury securities or money market mutual funds as well as the performance bond assets of a defaulting firm can be used to collateralize the facility. At March 31, 2014, guaranty funds available to collateralize the facility totaled $5.6 billion. We have the option to request an increase in the line from $7.0 billion to $10.0 billion. In addition to the 364-day multi-currency line of credit, we also have the option to use the $1.8 billion multi-currency revolving senior credit facility to provide liquidity for our clearing houses in the unlikely event of default in certain circumstances.

In addition, our 364-day multi-currency line of credit contains a requirement that CME remain in compliance with a consolidated tangible net worth test, defined as CME consolidated shareholder's equity less intangible assets (as defined in the agreement) of not less than $800.0 million.

The indentures governing our fixed rate notes, our $1.8 billion multi-currency revolving senior credit facility and our 364-day multi-currency line of credit for $7.0 billion do not contain specific covenants that restrict the ability to pay dividends. These documents, however, do contain other customary financial and operating covenants that place restrictions on the operations of the company that could indirectly affect the ability to pay dividends.

At March 31, 2014, we have excess borrowing capacity for general corporate purposes of approximately $1.8 billion under our multi-currency revolving senior credit facility.

As of March 31, 2014, we were in compliance with the various covenant requirements of all our debt facilities.

To satisfy our performance bond obligation with Singapore Exchange Limited, we may pledge CME-owned U.S. Treasury securities in lieu of, or in combination with, irrevocable letters of credit. At March 31, 2014, the letters of credit totaled $460.0 million.

The following table summarizes our credit ratings as of March 31, 2014:

	Short-Term	Long-Term
Rating Agency	Debt Rating	Debt Rating	Outlook
Standard & Poor’s	A1+	AA-	Stable
Moody’s Investors Service	P1	Aa3	Stable

Given our cash flow generation, our ability to pay down debt levels and our ability to refinance existing debt facilities if necessary, we expect to maintain an investment grade rating. If our ratings are downgraded below investment grade due to a change of control, we are required to make an offer to repurchase our fixed rate notes at a price equal to 101% of the principal amount, plus accrued and unpaid interest.

Liquidity and Cash Management. Cash and cash equivalents totaled $1.1 billion at March 31, 2014 and $2.5 billion at December 31, 2013. The balance retained in cash and cash equivalents is a function of anticipated or possible short-term cash needs, prevailing interest rates, our investment policy and alternative investment choices. A majority of our cash and cash equivalents balance is invested in money market mutual funds that invest only in U.S. Treasury securities or U.S. government agency securities. Our exposure to credit and liquidity risk is minimal given the nature of the investments. Cash that is not available for general corporate purposes because of regulatory requirements or other restrictions is classified as restricted cash and is included in other current assets or other assets in the consolidated balance sheets.

Net current deferred tax assets of $52.5 million and $52.3 million were included in other current assets at March 31, 2014 and December 31, 2013, respectively. Total net current deferred tax assets are attributable to unrealized losses, stock-based compensation and accrued expenses.

Net long-term deferred tax liabilities were $7.3 billion and $7.2 billion at March 31, 2014 and December 31, 2013, respectively. Net deferred tax liabilities are principally the result of purchase accounting for intangible assets in our various mergers, including CBOT Holdings and NYMEX Holdings.

Valuation allowances of $37.5 million and $47.5 million have been provided at March 31, 2014 and December 31, 2013, respectively. At March 31, 2014 and December 31, 2013, valuation allowances were related to domestic net operating losses, foreign net operating losses as well as built in capital losses for which we do not believe that we currently meet the more-likely-than-not-threshold for recognition.

Regulatory Requirements. CME is regulated by the Commodity Futures Trading Commission (CFTC) as a U.S. Derivatives Clearing Organization (DCO). DCOs are required to maintain capital as defined by the CFTC in an amount at least equal to one year of projected operating expenses as well as cash, liquid securities, or a line of credit at least equal to six months of projected operating expenses. CME is in compliance with the DCO financial requirements.

CME, CBOT, NYMEX, and COMEX are regulated by the CFTC as Designated Contract Markets (DCM). DCMs are also required to maintain capital as defined by the CFTC in an amount at least equal to one year of projected operating expenses as well as cash, liquid securities, or a line of credit at least equal to six months of projected operating expenses. Our DCMs are in compliance with the DCM financial requirements.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Earnings Per Share [Abstract]

Earnings Per Share

Earnings Per Share

Basic earnings per share is computed by dividing net income attributable to the company by the weighted average number of shares of all classes of CME Group common stock outstanding for each reporting period. Diluted earnings per share reflects the increase in shares using the treasury stock method to reflect the impact of an equivalent number of shares of common stock if stock options were exercised and restricted stock awards were converted into common stock. Anti-dilutive stock options and restricted stock awards were as follows for the periods presented:

	Quarter Ended March 31,

Legal and Regulatory Matters. In 2008, Fifth Market, Inc. (Fifth Market) filed a complaint against CME Group and CME in the Delaware District Court seeking a permanent injunction against CME's Globex system and unquantified enhanced damages for what the plaintiff alleges is willful infringement of two patents, in addition to costs, expenses and attorneys' fees. The case was stayed pending the outcome of CME's request for reexamination by the U.S. Patent and Trademark Office (USPTO). The reexaminations resulted in some claims being rejected and others being confirmed. In June 2013, the court lifted the stay. The validity of the patents, however, remains subject to further review by the USPTO. Based on its investigation to date and advice from legal counsel, the company believes this suit is without merit and intends to defend itself vigorously against these charges.

In 2009, CME and CBOT filed a complaint against Howard Garber in the Northern District of Illinois seeking a declaratory judgment that neither CME nor CBOT infringed the Garber patent, which relates to electronic market makers, and that the patent is invalid and unenforceable. The Technology Research Group (TRG) was substituted for Mr. Garber in 2009 and TRG filed counterclaims alleging patent infringement and other related claims. In 2011, the case was dismissed with the right to reinstate pending the outcome of a reexamination by the USPTO. In August and October 2013, the USPTO issued actions resulting in the rejection of all TRG’s claims completing the reexamination process. In January 2014, TRG appealed the decision of the USPTO. Based on its investigation to date and advice from legal counsel, the company believes this suit is without merit and intends to defend itself vigorously against these charges.

The foregoing legal matters involve alleged infringements of intellectual property which, due to their nature, involve potential liability that is uncertain, difficult to quantify and involves a wide range of potential outcomes. The company believes that the matters are without merit, and the company intends to defend itself vigorously against the claims. We expect the re-examinations by the USPTO in the Fifth Market and Garber matters, including any appeals thereof, to result in a determination of the validity of the patents at issue which we expect will have an impact on the merits of the matters. Given the uncertainty of factors which may potentially impact the resolution of these matters, at this time the company is unable to estimate the reasonably possible loss or range of reasonably possible loss in the unlikely event it were found to be liable at trial in these matters.

A number of lawsuits were filed in federal court in New York on behalf of all commodity account holders or customers of MF Global who had not received a return of 100% of their funds. These matters have been consolidated into a single action in federal court in New York, and a consolidated amended class action complaint was filed on November 5, 2012. On November 6, 2013, CME announced that it has reached an agreement in principle to resolve the class action litigation. In an agreement between the trustee and CME, CME will be allowed to assert a $29.0 million claim against MF Global based on expenses incurred by CME as a result of MF Global’s bankruptcy. In a separate agreement between CME and the customer representatives, CME has agreed to deliver $14.5 million, one-half of the distribution that it will receive from the trustee, to the customer representatives for distribution to MF Global’s former customers. In connection with the settlements between the company and the trustee and the customers, the company’s $550.0 million financial guarantee to the bankruptcy trustee to cover any shortfall in the bankruptcy will be extinguished. The company believes that the likelihood of payment to the trustee is very remote. As a result, the guarantee liability is estimated to be immaterial at March 31, 2014.

In February 2013, the CFTC filed suit against NYMEX and two former employees alleging disclosure of confidential customer information in violation of the Commodity Exchange Act. Based on the initial review of the complaint, the company believes that it has strong factual and legal defenses to the claim.

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

In addition, the company is a defendant in, and has potential for, various other legal proceedings arising from its regular business activities. While the ultimate results of such proceedings against the company cannot be predicted with certainty, the company believes that the resolution of any of these matters on an individual basis will not have a material impact on its consolidated financial position or results of operations.

At March 31, 2014 and December 31, 2013, the company had accrued $4.3 million and $11.3 million, respectively, for legal and regulatory matters that were probable and estimable.

Intellectual Property Indemnifications. Certain agreements with customers and other third parties related to accessing the CME platforms; utilizing market data services; and licensing CME SPAN software may contain indemnifications from intellectual property claims that may be made against them as a result of their use of the applicable products and/or services. The potential future claims relating to these indemnifications cannot be estimated and therefore no liability has been recorded.

Guarantees

Mutual Offset Agreement. CME and Singapore Exchange Limited (SGX) have a mutual offset agreement with a current term through October 2014. This agreement enables market participants to open a futures position on one exchange and liquidate it on the other. The term of the agreement will automatically renew for a one-year period unless either party provides advance notice of their intent to terminate. CME can maintain collateral in the form of U.S. Treasury securities or irrevocable, standby letters of credit. At March 31, 2014, CME was contingently liable to SGX on letters of credit totaling $460.0 million. Regardless of the collateral, CME guarantees all cleared transactions submitted through SGX and would initiate procedures designed to satisfy these financial obligations in the event of a default, such as the use of performance bonds and guaranty fund contributions of the defaulting clearing firm. The company believes that its guarantee liability is immaterial and therefore has not recorded any liability at March 31, 2014.

Family Farmer and Rancher Protection Fund. In April 2012, the company established the Family Farmer and Rancher Protection Fund (the Fund). The Fund is designed to provide payments, up to certain maximum levels, to family farmers, ranchers and other agricultural industry participants who use the company's agricultural products and who suffer losses to their segregated account balances due to their CME clearing member becoming insolvent. Under the terms of the Fund, farmers and ranchers are eligible for up to $25,000 per participant. Farming and ranching cooperatives are eligible for up to $100,000 per cooperative. The Fund was established with a maximum payment amount of $100.0 million. Since its establishment, the Fund has made payments of approximately $2.0 million, which leaves $98.0 million available for future claims. If payments to participants were to exceed the amount remaining in the fund at the time of insolvency, payments would be pro-rated. Clearing members and customers must register in advance with the company and provide certain documentation in order to substantiate their eligibility. The company believes that its guarantee liability is immaterial and therefore has not recorded any liability at March 31, 2014.

Fair Value Measurements

Fair Value, Assets, Liabilities and Stockholders' Equity Measured on Recurring Basis [Abstract]

Fair Value Measurements

Fair Value Measurements

The company uses a three-level classification hierarchy of fair value measurements for disclosure purposes.

• Level 1 inputs, which are considered the most reliable evidence of fair value, consist of quoted prices (unadjusted) for identical assets or liabilities in active markets.

• Level 2 inputs consist of observable market data, 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 consist of unobservable inputs which are derived and cannot be corroborated by market data or other entity-specific inputs.

Level 1 assets generally include U.S. Treasury securities and investments in publicly traded stocks and mutual funds with quoted market prices. In general, the company uses quoted prices in active markets for identical assets to determine the fair value of marketable securities and equity investments. If quoted prices are not available to determine fair value, the company uses other inputs that are directly observable.

Assets included in level 2 generally consist of asset-backed securities. Asset-backed securities were measured at fair value based on matrix pricing using prices of similar securities with similar inputs such as maturity dates, interest rates and credit ratings.

The company determined the fair value of its contingent consideration liabilities, considered level 3 liabilities, using a discounted cash flow model to calculate the present value of future payouts. The liabilities were included in level 3 because management used significant unobservable inputs, including a discount rate of 20% and payout probabilities of either 75% or 100%. Significant increases or decreases in any of those inputs in isolation would result in a significantly different fair value.

Financial assets and liabilities recorded in the consolidated balance sheet as of March 31, 2014 were classified in their entirety based on the lowest level of input that was significant to each asset or liability's fair value measurement. The following presents financial instruments measured at fair value on a recurring basis:

	March 31, 2014
(in millions)	Level 1		Level 2		Level 3		Total
Assets at Fair Value:
Marketable securities:
U.S. Treasury securities	$	19.2	$	—	$	—	$	19.2
Mutual funds	52.6		—		—		52.6
Asset-backed securities	—		0.4		—		0.4

Liabilities at Fair Value:
Contingent consideration	$	—	$	—	$	19.2	$	19.2
Total Liabilities at Fair Value	$	—	$	—	$	19.2	$	19.2

There were no transfers of assets or liabilities between level 1 and level 2 during the first quarter of 2014. The following is a reconciliation of liabilities valued at fair value on a recurring basis using significant unobservable inputs (level 3) during the first quarter of 2014. There were no assets valued at fair value on a recurring basis using significant unobservable inputs (level 3) during the first quarter of 2014.

(in millions)	Contingent Consideration
Fair value of liability at December 31, 2013	$	15.7
Realized and unrealized (gains) losses:
Included in other expenses	3.5
Fair value of liability at March 31, 2014	$	19.2

There were no assets or liabilities valued at fair value on a nonrecurring basis using significant unobservable inputs (level 3) during the first quarter of 2014.

Performance Bonds and Guaranty Fund Contributions [Abstract]

Performance Bonds and Guaranty Fund Contributions [Text Block]

Performance Bonds and Guaranty Fund Contributions

Performance Bonds and Guaranty Fund Contributions. At March 31, 2014, performance bonds and guaranty fund contributions in the consolidated balance sheet included performance bond and guaranty fund contributions received in the form of cash that were reinvested by CME in U.S. Treasury securities with maturity dates of 30 days or less. Any interest earned on these U.S. Treasury investments accrues to CME and is included in the consolidated statements of income. Because CME has control of the cash collateral reinvested in U.S. Treasury securities and the benefits and risks of ownership accrue to CME, these performance bonds and guaranty fund contributions are reflected in the consolidated balance sheets. The amortized cost and fair value of the U.S. Treasury securities were both $2.9 billion as of March 31, 2014. The U.S. Treasury securities matured on April 3, 2014. The U.S. Treasury securities are considered a level 1 asset under the classification hierarchy for fair value measurements because the securities are valued using a quoted price in an active market.

Clearing House Contract Settlement. CME and CME Clearing Europe Limited (CMECE) mark-to-market open positions for all products at least once a day (twice a day for futures and options contracts). Based on values derived from the mark-to-market process, CME and CMECE require payment from clearing firms whose positions have lost value and make payments to clearing firms whose positions have gained value. Under the extremely unlikely scenario of simultaneous default by every clearing firm who has open positions with unrealized losses, the maximum exposure related to positions other than over-the-counter credit default and interest rate swap contracts would be one half day of changes in fair value of all open positions, before considering the clearing houses' ability to access defaulting clearing firms' collateral deposits. For CME's cleared over-the-counter credit default swap and interest rate swap contracts, the maximum exposure related to CME's guarantee would be one full day of changes in fair value of all open positions, before considering CME's ability to access defaulting clearing firms' collateral. During the first quarter of 2014, the clearing houses transferred an average of approximately $2.8 billion a day through their clearing systems for settlement from clearing firms whose positions had lost value to clearing firms whose positions had gained value. The clearing houses reduce the guarantee exposure through initial and maintenance performance bond requirements and mandatory guaranty fund contributions. The company believes that the guarantee liability is immaterial and therefore has not recorded any liability at March 31, 2014.
