ITEM 1.    BUSINESS

CME Group provides market participants worldwide the ability to efficiently manage risk across multiple asset classes, by trading futures, options, cash and over-the-counter (OTC) products. CME Group also offers a suite of products and services to optimize portfolios, achieve capital efficiencies and manage pre-trade and post-trade processes. Our customers can receive and analyze market data through multiple service offerings in real-time, historical and derived data formats. CME Group also offers industry-leading research and analytics tools to provide customers with market education resources.

GENERAL DEVELOPMENT OF BUSINESS

CME was founded in 1898 as a not-for-profit corporation. It established CME Clearing in 1919, which is operated by CME. CME demutualized in 2000, and in 2002 its parent company, CME Group, completed an initial public offering of its Class A common stock (Nasdaq: CME). CME Group subsequently acquired CBOT Holdings, Inc. in 2007, NYMEX Holdings, Inc. (NYMEX and COMEX) in 2008, the Kansas City Board of Trade in 2012 and NEX Group plc (NEX) in 2018. The combination with NEX expanded our global customer base and product offerings through the complementary combination of CME Group’s exchange-traded derivative products and NEX’s cash and OTC products. It also created a leading, client-centric, global markets company, generating capital efficiencies across futures, cash and OTC products for market participants seeking to lower their cost of trading and better manage risk. Our principal executive offices are located at 20 South Wacker Drive, Chicago, Illinois 60606, our telephone number is 312-930-1000 and our website is cmegroup.com.

DESCRIPTION OF BUSINESS

CME Group exchanges offer the widest range of global benchmark products across interest rates, equity indexes, foreign exchange (FX), agricultural commodities, energy and metals. We also offer cash and repo fixed income trading via BrokerTec, and cash and OTC FX trading via EBS.

In addition, we operate one of the world’s leading central counterparty clearing providers, CME Clearing, operated by CME. With a range of pre- and post-trade products and services underpinning the entire lifecycle of a trade, CME Group offers optimization, reconciliation and processing services through Traiana, TriOptima and Reset.

Derivatives Exchange Business: Through our derivatives exchanges and clearing house, we believe our customers prefer CME Group's diversity of products, liquidity, price transparency and technological capabilities. Market liquidity - or the ability of a market to absorb the execution of large purchases or sales quickly and efficiently - is key to attracting and retaining customers and contributing to a market's success. Our products provide a means for hedging, speculation and asset allocation related to the risks associated with, among other things, interest rate sensitive instruments, equity ownership, changes in the value of foreign currency and changes in the prices of agricultural, energy and metal commodities.

•CME's product slate includes agricultural, equities, FX and interest rate products, including Eurodollar futures and options, Secured Overnight Financing Rate (SOFR) futures and options, livestock and cash-settled contracts based on the S&P 500, including the E-mini S&P 500 Environmental, Social and Governance (ESG) contract, Micro E-mini Equity Index contracts, Nasdaq-100, FTSE Russell and Bitcoin Reference Rate.

•CBOT's product slate consists of agricultural, equities and interest rate products, including contracts for United States (U.S.) Treasury futures, soybean, corn, wheat and contracts based on the Dow Jones Industrial Index.

•NYMEX's product slate consists of energy and metals products, including contracts for crude oil, natural gas, heating oil and gasoline.

•COMEX's product slate consists of metals products, including contracts for gold, silver, copper and other base metals.

We believe the breadth and diversity of our products and services lines are beneficial to our customers and CME Group's overall performance. Our asset classes contain products designed to address differing risk management needs, and customers are able to manage risks and achieve operational and capital efficiencies by accessing our diverse products through our platforms and our clearing house.

CME Group products are traded primarily through CME Globex, as well as by open outcry auction markets in Chicago and through privately negotiated transactions. Due to the COVID-19 pandemic, in March 2020 we closed our open outcry trading floor and reopened it in August 2020 for Eurodollar options. Currently, the remainder of the trading floor is closed.

We strive to provide the most flexible and scalable platforms to support the operational and capacity needs of the business along with the delivery of innovative technology solutions to the marketplace. Our CME Globex electronic platform is the trading engine for our central limit order book markets and is available on a global basis nearly 24 hours a day throughout the trading week. The CME Globex platform is accessible through a wide variety of vendor-provided and custom-built trading systems that benefit from our open application programming interface approach. For privately negotiated markets, we offer brokers and customers the CME Direct platform for arranging, executing, recording and risk-managing trades. CME Direct

5

includes CME One for mobile access and CME Straight-Through Processing, which enables direct connectivity for trade information directly with customer order management and risk management systems and is designed to reduce errors and improve efficiency.

Together, our platforms offer:

•certainty of execution;

•extensive capabilities to facilitate complex and demanding trading;

•direct market access;

•fairness, price transparency and anonymity;

•convenience and efficiency;

•connectivity through highly secure, resilient and low-latency network options;

•access to market data; and

•global distribution, including connectivity through high-speed international telecommunications hubs in key financial centers or order routing to our global partner exchanges.

We maintain comprehensive business continuity and disaster recovery plans and facilities designed to provide nearly continuous availability of our markets in the event of a business disruption or disaster. We also maintain incident and crisis management plans that address responses to disruptive events.

The customer base of our derivatives exchanges includes professional traders, financial institutions, institutional and individual investors, major corporations, manufacturers, producers, governments and central banks. Customers may be members of one or more of our exchanges. Rights to directly access our derivatives markets will depend upon the nature of the customer, such as whether the entity or individual is a member of one of our exchanges or has executed an agreement with us for direct access.

U.S. trading rights and privileges are exchange-specific. Open outcry trading is conducted exclusively by our members. Membership on one of our derivatives exchanges also enables a customer to trade specific products at lower fees. Under the terms of the organizational documents of our exchanges, our members have certain rights that relate primarily to trading right protections, certain trading fee protections and certain membership benefit protections. In 2020, 83% of our contract volume was from trades by our members.

CME Clearing Business: Through our clearing house, CME Clearing, which is operated by CME, we provide clearing and settlement services for a broad range of exchange-traded futures and options on futures contracts and over-the-counter derivatives. Our integrated clearing function is designed to ensure the safety and the soundness of our markets by serving as the counterparty to every trade, becoming the buyer to each seller and the seller to each buyer, and limiting counterparty credit risk. CME Clearing marks open positions to market at least twice a trading day, requiring payments from clearing firms whose positions have lost value and making payments to clearing firms whose positions have gained value. For select cleared-only markets, positions are marked-to-market daily, with the capacity to mark-to-market more frequently as market conditions warrant. The CME ClearPort front-end system provides access to our flexible clearing services for block transactions, bi-lateral trades and swaps.

The majority of clearing and transaction fees received from clearing firms represents charges for trades executed and cleared on behalf of their customers. One firm represented at least 10% of our clearing and transaction fees revenue for 2020. In the event a clearing firm were to withdraw, our experience indicates that the customer portion of the firm's trading activity would likely transfer to one or more other clearing firms of the exchange.

Cash Markets Business: Our cash markets business is comprised of BrokerTec and EBS. Certain BrokerTec and EBS contracts are cleared at third-party clearing houses. BrokerTec and EBS offer anonymous and disclosed trading venues, offering clients multiple execution and distribution options and the benefit of an established and far-reaching distribution network of liquidity providers and consumers. Our BrokerTec markets were migrated from a third-party platform to our CME Globex electronic platform in the first quarter of 2021 and our EBS market is expected to migrate to the CME Globex platform in the fourth quarter of 2021.

•BrokerTec operates global electronic trading for fixed income products on the CME Globex platform, with a leading position in cash U.S. Treasuries, E.U. and U.S. repo fixed income instruments and European Government Bonds. It facilitates trading principally for banks and non-bank professional trading firms.

•EBS is a global electronic platform for the trading of FX products across major and emerging market currencies.EBS also offers execution of non-deliverable forwards through a Commodity Futures Trading Commission (CFTC) registered Swap Execution Facility (SEF).

Optimization Business: Our optimization services, which include Traiana, TriOptima and Reset, deliver transaction lifecycle management services to help our clients simplify their workflow, optimize their capital and resources, mitigate their risk, increase efficiency, reduce their operational costs and streamline complex processes.

•Trade and portfolio management comprises portfolio and margin reconciliation, monitoring pre-trade risk and automating post-trade processing of financial transactions.

•Financial resource optimization comprises portfolio compression, basis risk mitigation, portfolio balancing and derivative pricing and risk analytics.

•Regulatory reporting comprises trade and position reporting (including licensed MiFID agent reporting to national regulators and the public), end-to-end multi-regime regulatory reporting, data normalization, enrichment, reconciliation, validation and cross-jurisdictional matching. In 2020, we substantially completed the wind-down of our commercial regulatory reporting operations. We have transitioned to self-reporting for our EMEA BrokerTec and EBS businesses and will also continue to serve customer reporting needs in the U.S. (CFTC reporting) and Canada.

•Trade Processing comprises end-to-end automation, from trade execution notification to trade confirmation of post-trade processing, in real-time to reduce operational risks and costs.

In January 2021, we announced an agreement with IHS Markit to combine our post-trade services into a new joint venture. The new company will be structured as a 50/50 joint venture and will include trade processing and risk mitigation operations through incorporation of our optimization businesses – Traiana, TriOptima and Reset – and IHS Markit’s MarkitSERV. We expect the transaction to close in mid-2021, subject to customary antitrust and regulatory approvals and other customary closing conditions.

Market Data Business: We offer a variety of market data services through industry-leading market data platforms and third-party distribution partners, which are designed to meet the risk-management, trading, investment and business needs of our global client base. As such, we provide proprietary real-time and historical market data related to CME Group’s vibrant and deeply liquid exchanges and cash markets businesses. We further offer derived cash markets pricing, third-party and alternative data sets, as well as a wide range of analytic tools. As customers continue to leverage cloud technology to improve and evolve their businesses, CME Group has taken a leading role by becoming the first derivatives marketplace to provide live market data natively in the cloud with the launch of our Smart Stream on Google Cloud Platform capabilities. CME Group is also the distributor of leading benchmark equity and commodity indices on behalf of third parties as well as our own proprietary indices, which include CME Group Volatility Indices (CVOL).

Our Strategic Initiatives

The following is a description of our strategic initiatives:

Maximize Futures and Options Growth Globally - We continue to focus on driving growth and new customer acquisition by expanding, innovating and scaling our core offerings, and increasing participation from non-U.S. customers. We do this by expanding our global sales team, cross-selling our products, expanding the strength of our existing benchmark products, launching new products and services and deepening open interest in our core futures and options offerings. We have further focused on building upon cloud-based data distribution capabilities as a more flexible and potentially cost-effective means of providing data to our clients.

In 2020, CME Group futures and options had an average daily volume of 19.1 million contracts, with volume records in two of our asset classes - equities and metals for the fifth consecutive year. It was also a year of volume records for multiple products, including: Ultra 10 Year futures, SOFR futures, E-mini Nasdaq-100 futures, Russell 2000 futures, Micro E-Mini Equity Index futures and a record number of contracts executed via Basis Trade at Index Close. We set records in the volume traded for our Micro E-Mini Equity Index futures in total, as well as for each of the Micro E-Mini S&P 500, Nasdaq-100, Russell 2000 and Dow 30 contracts. We also set an overall volume record for the Natural Gas franchise, as well as an individual product record in Silver futures.

We continue to expand and deepen our customer base worldwide and offer customers around the world the most broad and diversified portfolio of benchmark products. Some of our products introduced over the past two years include:

•3-Year Treasury Note Futures (2020)

•Adjusted Interest Rate (AIR) Total Return Futures (2020)

•Trade at Cash Open (TACO) (2019)

•Cash-settled Bitcoin Options (2020)

•SOFR Options (2020) and SOFR OTC Swaps (2019)

•Shanghai Gold Futures (2019)

•Physical Liquefied Natural Gas (LNG) Futures (2019)

•Micro E-mini Equity Index Futures (2019) and Options (2020)

•E-mini S&P 500 ESG Index Futures (2019)

•Brazilian Soybean Futures (2020)

•Pork Cutout Futures and Options (2020)

7

•European Renewable Fuel Futures (2020)

•Nasdaq-100 Volatility Index (VOLQ) Futures (2020)

•Nasdaq Veles California Water Index Futures (2020)

•Adjusted Interest Rate Total Return Futures (2020)

In addition to the individual product launches noted above, we have completed many product extensions across our asset classes, including short-dated options products, monthly FX futures, additional grades in our crude oil complex and expansion of our metals complex with additional base metals products.

We continue to expand and deepen our customer base worldwide and offer customers around the world with the most broad and diversified portfolio of benchmark products. We believe we have a significant opportunity to expand the participation of our non-U.S. customer base in our markets. Our penetration of these markets lags our development in the U.S., and we believe that there is room for significant growth and development of these financial markets. In 2020, approximately 28% of our electronic futures and options volume was from transactions reported as outside the U.S. and approximately 55% of our market data revenue was derived from outside the U.S. We also achieved 20% growth in trading volume during Asian trading hours and 6% growth during European trading hours in 2020 compared to 2019.

In 2020, we launched four proprietary tools to enable customers to link and compare opportunities across OTC, cash and futures markets: FX Swap Rate Monitor, FX Options Vol Converter, TreasuryWatch Tool and FX Market Profile Tool.

Our CME Liquidity Tool enables market participants to analyze liquidity across CME Group products during U.S., London or Singapore trading hours. To further our commitment to our international customers, in 2020 we introduced a TreasuryWatch Tool and additional tools to help customers and prospective customers identify key marketplace developments and potential risk management and trading opportunities (e.g., SOFR-LIBOR spread). Also in 2020, we began daily publication of a suite of new implied volatility benchmark indexes based on our innovative and proprietary CME Group Volatility Index (CVOL) methodology, starting with 10-Year Treasuries and FX currency pairs. We have increased our customer base and continue to target cross-asset sales across client segments, driving international sales and generating new client participation across all regions. We have a long history of providing customer value and responsiveness and believe our products and services position us to help our customers adapt and comply with new regulations, while enabling them to efficiently manage their risks. We have a broad distribution network comprised of a combination of internal and external channels and proprietary front-end capabilities.

Diversify our Business and Revenue - Our acquisition of NEX strengthened our role in global financial markets infrastructure and information services, adding complementary cash and OTC businesses and scale to our listed interest rate and FX products, while enabling new efficiencies for the derivatives marketplace. We are positioned to take direct advantage of growth in treasury issuance, liquid treasury holdings and the trading of treasury instruments, as well as growing repo activity in the U.S. and Europe. The transaction expanded CME Group’s position in the large, highly competitive and highly fragmented global FX marketplace, offering both order book trading and relationship-based trading solutions for customers. The acquisition added strength in underlying customer marketplaces, especially around regional bank customers and other market participants outside of North America and expanded our post-trade and trade-processing services and market data solutions beyond futures and options into cash and OTC offerings.

Our joint venture with S&P Global, Inc., S&P/DJI Indices LLC, combines the world class capabilities of the S&P and Dow Jones Indices, and is a significant player in passive investing, including the exchange-traded fund (ETF) industry value chain. As part of the joint venture, we acquired a long-term, ownership-linked, exclusive license to list futures and options based on the S&P 500 Index and certain other S&P indices. We also act as the joint ventures' licensing agent and distribution services provider.

Deliver Unparalleled Customer Efficiencies and Operational Excellence - With changing regulatory capital requirements for many of our customers, including additional margin requirements on uncleared trades, and the need for greater efficiencies, we have added tools to enable customers to manage trading and clearing positions in our markets in an efficient manner. With the ongoing implementation of regulatory reform in the U.S. and in Europe, along with global implementation of Basel III capital requirements on financial institutions, we expect capital efficiencies and centralized clearing to continue to be important for our global client base.

We provide a comprehensive multi-asset class clearing solution to market participants for maximum operational ease and the capital efficiency that comes with connecting to our clearing house. Our clearing services offer the ability to optimize collateral and capital efficiencies across portfolios within the clearing house while meeting the heightened regulatory requirements on derivatives. The majority of our clearing volumes and activities are related to our listed futures and options, which represents the majority of our open interest and collateral held against these positions. We also offer clearing services for OTC interest rate swaps, FX forwards and commodity swaps. The addition of our enhanced Standard Portfolio Analysis of Risk (SPAN) margin framework – CME SPAN 2, will provide enhanced risk management capabilities in a single, unified interface by maintaining

8

SPAN's current calculations and functions while incorporating several new modeling, reporting and margin replication enhancements. CME SPAN 2 will be launched in a phased multi-year approach, starting in 2021 with certain futures and options on energy products. Over the next few years, as SPAN 2 is expanded to other asset classes, margins for diversified portfolios will consist of products using the enhanced CME SPAN 2 framework in addition to the existing SPAN framework, ensuring appropriate levels of offsets will continue to be provided across products subject to the SPAN and SPAN 2 frameworks.

CME Group provides various tools and services to assist customers with capital and operational efficiencies, including:

•CME Clearing provides compression via coupon blending as well as CME CORE, an interactive margin calculator that enables clients to optimize their capital by providing insights on margin requirements prior to trading.

•triReduce provides multilateral portfolio compression, which reduces notional outstanding exposure and line items in order to reduce operational resources and risks, minimize regulatory capital costs, and manage counterparty exposures.

•triResolve provides the global trading community with tools for portfolio reconciliation and collateral management, including compliance with initial margin and uncleared margin rules (UMR).

•Traiana provides various operational efficiencies and risk mitigation solutions to clients through bilateral and tri-party pre- and post-trade processing and credit risk management.

•Reset provides risk mitigation services to clients looking to hedge short-term interest rate and options expiry exposure.

•Under our newly announced agreement with IHS Markit, the joint venture will incorporate our optimization businesses – Traiana, TriOptima and Reset – and IHS Markit’s MarkitSERV. We expect the transaction to close in mid-2021, subject to customary antitrust and regulatory approvals and other customary closing conditions.

Patents, Trademarks and Licenses

We own the rights to a large number of trademarks, service marks, domain names and trade names in the U.S., Europe and other parts of the world. We have registered many of our most important trademarks in the U.S. and other countries. We hold the rights to a number of patents and have a number of patent applications pending. Our patents cover match engine, trader user interface, trading floor support, market data, general technology and clearing house functionalities. We also own copyrights to a variety of materials. Those copyrights, some of which are registered, include printed and on-line publications, websites, advertisements, educational materials, graphic presentations and other literature, both textual and electronic. We protect our intellectual property rights by relying on trademarks, patents, copyrights, database rights, trade secrets, restrictions on disclosure and other methods.

We offer equity index futures and options on key benchmarks, including S&P, Nasdaq, Dow Jones and the FTSE Russell indexes. These products are listed by us subject to license agreements with the applicable owners of the indexes, some of which are exclusive. In connection with our joint venture with S&P Global, Inc., we have a license agreement (S&P License Agreement), which superseded our prior licensing arrangements and was assigned to the joint venture. CME’s license for the S&P 500 Index will be exclusive for futures and options until one year prior to the termination of the S&P License Agreement, and non-exclusive for the last year. The license for the other S&P stock indexes is generally exclusive for futures and options. The term of the S&P License Agreement will continue until the date that is one year after the date that CME Group ceases to own at least five percent (accounting for dilution) of the outstanding joint venture interests. Upon the occurrence of certain events, including certain terminations of the joint venture, the term may be extended up to an additional ten years. CBOT has an exclusive license agreement (Dow Jones License Agreement) with CME Group Index Services LLC (CME Indexes) for certain Dow Jones indexes, which has also been assigned to the joint venture. The initial term of the agreement is through June 30, 2026. Following the initial term, the Dow Jones License Agreement shall automatically renew for renewal terms of five years thereafter so long as there is open interest in any of CBOT’s or its affiliates’ products based on one or more of the Dow Jones licensed indexes. In the event there is no open interest in any such products, then CME Indexes may terminate the agreement. We also have an exclusive license agreement for certain Nasdaq indexes through 2029. In 2015, we entered into an exclusive license agreement with FTSE Russell and launched the E-mini Russell 2000 futures in 2017. We pay the applicable third-party, per-trade fees based on contract volume under the terms of these licensing agreements. A copy of the S&P License Agreement has been filed as a material contract. We also have a multi-year non-exclusive licensing arrangement with ICE Benchmark Administration for the use of LIBOR to settle several of our interest rate products, including our Eurodollar contracts.

We cannot guarantee that we will be able to maintain the exclusivity of our licensing agreements with S&P, Dow Jones, Nasdaq and FTSE Russell or be able to maintain existing exclusive and non-exclusive licensing arrangements beyond the term of the current agreements or that any renewal will be on terms as favorable to us. In addition, we cannot guarantee that others will not succeed in creating stock index futures based on information similar to that which we have obtained by license, or that market participants will not increasingly use other instruments, including securities and options based on the S&P, Dow Jones, Nasdaq or FTSE Russell indexes, to manage or speculate on U.S. stock risks. Parties also may succeed in offering indexed products that

9

are similar to our licensed products without being required to obtain a license, or in countries that are beyond our and/or our licensors' jurisdictional reach.

Competition

The industry in which we operate is highly competitive, has seen multiple new entrants over time, and we expect competition to continue to intensify and become more global, especially in light of changes in the financial services industry driven by regulatory reforms such as the Dodd-Frank Wall Street Reform and Consumer Protection Act (Dodd-Frank), European Market Infrastructure Regulation (EMIR),  EMIR 2.2, Markets in Financial Instruments Directive II (MiFID II), Capital Requirements Directive IV, Market Abuse Regulation, Benchmarks Regulation, Basel III, and various other laws and regulations.

Please also refer to the discussion below and in the “Risk Factors” section beginning on page 15 for a description of competitive risks and uncertainties.

Competition in our Derivatives Exchange Business

We believe competition in the derivatives business is based on a number of factors, including, among others:

•brand and reputation;

•efficient and secure settlement, clearing and support services;

•depth and liquidity of markets;

•diversity of product offerings and frequency and quality of new product development and innovative services;

•ability to position and expand upon existing products to address changing market needs;

•efficient and seamless customer experience;

•transparency, reliability, anonymity and security in transaction processing;

•regulatory environment;

•connectivity, accessibility, flexibility in execution methods, and distribution;

•technological capability and innovation; and

•overall transaction costs. 

We believe that we compete favorably with respect to these factors. Our deep, liquid markets; diverse and complementary product offerings; frequency and quality of new product development, and efficient, secure settlement, clearing and support services, distinguish us from others in the industry. We believe that in order to maintain our competitive position, we must continue to expand globally; develop and offer new and innovative products; enhance our technology infrastructure, including its reliability, functionality and security; maintain liquidity and low transaction costs; continue to strengthen our risk management capabilities and solutions, and implement customer protections designed to ensure the integrity of our market and the confidence of our customers.

We compete in a large and expanding financial services trading, clearing and settlement marketplace globally. Our competitors include, among other entities, exchanges such as Intercontinental Exchange, Inc. (ICE), the Hong Kong Exchanges and Clearing Limited, and Deutsche Börse AG. Competition also includes alternative means of developing exposures through alternative instruments (depending on market factors) such as cash, OTC, ETFs, options, warrants, contracts for differences, structured products, and other offerings and incorporates large customer and channel internalization of trade flows and data. New emerging competitors have targeted different segments of our industry, with multiple execution models and products, and emerging technologies will continue to offer additional alternative products in the future. Competition in our industry continues to be dynamic and recent developments and alliances may result in a growing number of well-capitalized trading service providers that compete with all or a portion of our business.

Competition in our CME Clearing Business

In the past few years, there has been increased competition in the provision of clearing services and we expect competition to continue to increase in connection with compliance with Dodd-Frank, EMIR 2.2, Basel III, MiFID II and other various laws and regulations.

Our competitors in the clearing services space include, among others, companies such as ICE, LCH Group, the Options Clearing Corporation, Depository Trust & Clearing Corporation, Hong Kong Exchanges and Clearing, Japan Securities Clearing Corporation, LME Clearing and Deutsche Börse AG. In light of the implementation of new regulatory requirements and other reforms of the financial services industry, we believe that other exchanges and infrastructure providers also may

10

undertake to provide clearing and other related post-trade services, such as Nodel and ERIS in the U.S., as CFTC regulated designated clearing organizations.

We believe competition in clearing services is based on, among other things, the value of providing customers with capital and margin efficiencies; quality and reliability of the services; creditworthiness of the clearing house; regulatory costs, timely delivery of the services; reputation; diversity of the service offerings; confidentiality of positions and information security protective measures; and the fees charged for the services provided.

Competition in our Cash Markets Business

The cash markets businesses face substantial competition across a wide array of venues. In the FX space, the marketplace is highly fragmented, and there is competition from other electronic communication networks, single dealer platforms, bank-owned multi-participant platforms, streaming and request for quote services, trading venues tied to data platforms, voice brokers, other broker enabled platforms and other venues. There is a growing array of platforms and technologies, and they are often owned by many well-capitalized financial institutions and intermediaries that are also driving internalization of client FX trade flows. In the fixed income space, there are also multiple providers of treasury, European and U.S. repo, and European bond trading, as well as other products such as corporate bonds, municipal bonds, mortgage-backed bonds and agencies, and a multitude of competitors and new entrants offering single-dealer liquidity, bank-owned multi-participant platforms, streaming and request for quote services, and other broker and exchange-enabled platforms.

Competition in our Optimization Services Business

The optimization services business faces substantial competition across each of the segments in which CME Group operates. There are multiple providers of compression services, reconciliation services, trade processing, analytics, and regulatory reporting services. In addition, there is considerable innovation occurring in this business, with new entrants and new technologies being developed to serve customers and differentiate offerings. Competition also comes from other clearing houses and exchange groups, who are today internalizing or have plans to internalize various services, as well as existing back office service providers, who may embed these services in their offerings.

Competition in our Market Data Business

Technology companies, market data and information vendors and front-end software vendors also represent actual and potential competitors because they have their own substantial market data distribution capabilities that could serve as alternative means for receiving open market data feeds instead of connecting directly to our exchange. Distributors and consumers of our market data may also use our market data as an input into a product that competes against one of our traded or cleared products. Although we may receive license fees for such products, such fees may not offset the impact of any loss in revenue from our comparable product.

Regulatory Matters

Our businesses are regulated and serve a customer-base that includes regulated institutions or individuals. Developments in the regulatory environment have the potential to significantly affect our businesses. As such, we are subject to extensive regulation primarily in the U.S. and Europe.

On January 31, 2020, the United Kingdom (U.K.) formally withdrew from the European Union (E.U.) after a majority of voters in the U.K. approved an exit from the E.U., commonly referred to as Brexit. As a result of Brexit, we have established certain businesses in Amsterdam, an E.U. jurisdiction, which will allow us to continue to provide services to E.U. clients. We have also entered into agreements to work with E.U.-based clearing venues to clear E.U. based repo traded products. Additionally, amendments to EMIR 2.2 became effective during 2020, which resulted in changes to the E.U. equivalence and recognition regime for non-E.U. clearing houses, including CME Clearing. The European Commission adopted several implementing and delegated acts relating to central counterparties established in third countries under the EMIR 2.2 revisions to the European Market Infrastructure Regulation.

Please also refer to the discussion below and in the “Risk Factors” section beginning on page 15 for a description of regulatory and legislative risks and uncertainties.

Regulation of our Derivatives Business, CME Clearing and our SEF

Our operation of U.S. futures exchanges, CME Clearing and our SEF is subject to extensive regulation by the CFTC that requires our regulated subsidiaries to satisfy the requirements of certain core principles relating to the operation and oversight of our markets and our clearing house. The CFTC carries out the regulation of the futures and swaps markets and clearing houses in accordance with the provisions of the Commodity Exchange Act as amended by, among others, the Commodity Futures Modernization Act and Dodd-Frank.

Regulations implementing Dodd-Frank include rules relating to the implementation of mandatory clearing of certain OTC derivatives, swap reporting, operation of a clearing house, anti-manipulation, large trader reporting, product definitions, the

11

definition of an agricultural commodity and certain provisions of the rules applicable to designated contract markets, swap execution facilities and swap data repositories.

CME has been designated as a systemically important financial market utility and a systemically important derivatives clearing organization. These designations carry with them additional regulatory oversight of certain of our risk-management standards, clearing and settlement activities by the CFTC and the Federal Reserve Board.

In connection with the global offering of our products and clearing services, this business is also subject to the rules and regulations of the local jurisdictions in which we conduct business, including the European Securities and Markets Authority (ESMA), the U.K. Financial Conduct Authority (FCA) and Bank of England and the Netherlands Authority for the Financial Markets (AFM).

Regulation of our Cash Markets Business

The operation of our BrokerTec platform subjects us to regulation by the Financial Industry Regulatory Authority (FINRA) and the U.S. Securities and Exchange Commission (SEC) as a broker-dealer and alternative trading system operator. It also subjects us to regulation by authorities in the E.U. as a multilateral trading facility and regulated market and by the applicable regulators in Singapore and Canada. Our EBS business holds various permissions, approvals and exemptions globally, including those that subject certain of its activities to CFTC, FCA, AFM and Hong Kong Monetary Authority (HKMA) oversight.

The settlement of matched principal and exchange-traded businesses requires access to clearing houses either directly or through third-party providers of clearing and settlement services. BrokerTec Americas is a member of the Fixed Income Clearing Corp. (FICC) through which it clears U.S. Treasury and repo products.

Regulation of our Optimization Services Business

Certain areas of our optimization services, which enable clients to mitigate their risk, reduce operational costs, optimize their capital, and fulfill trade reporting obligations, are subject to regulatory oversight in those jurisdictions in which we conduct business, including the Swedish Financial Supervisory Authority, the FCA, CFTC, the National Futures Association, ESMA, the Australian Securities and Investments Commission and HKMA.

Regulation of our Market Data Business

A portion of our market data business, offered by CME Group Benchmark Administration, is subject to regulation by the E.U. Benchmarks Regulation, which regulates our RepoFunds Rate suite of daily Euro repo indices.

Key Areas of Focus

We actively monitor and participate in the domestic and international rulemaking processes for our industry, including providing government testimony, commenting on proposed rulemaking and educating our regulators on potential impacts to the marketplace. We are also focused on the new U.S. Presidential administration and any anticipated changes that may result.

Our key areas of focus in the regulatory environment are:

•The potential impact of the adoption of EMIR 2.2 allowing for the direct regulation by the E.U. of non-E.U. clearing houses, like ours, and resulting changes to the E.U. equivalence and recognition regime on non-E.U. clearing houses and exchanges with customers based in Europe. EMIR 2.2 became effective on January 1, 2020, and as of December 31, 2020, we do not anticipate a significant impact to our business.

•Rules respecting capital charges under Basel III with respect to clearing members of central counterparties may have negative implications for the cleared derivatives markets. Additional risks could arise through inconsistent adoption of the Basel III capital charges globally, potentially leading to disparate impacts on our customers.

•The potential for further regulation stemming from industry performance disruptions and residual concerns around electronic trading activity and, in particular, "high frequency trading."

•The potential elimination of the 60/40 tax treatment of certain of our futures and options contracts, which would result in 60% of the gains being taxed at the short-term capital gain rate instead of the long-term capital gain rate. This would impose a significant increase in tax rates applicable to certain market participants and could result in a decrease in their trading activity.

•The implementation of a transaction tax or user fee in the U.S., U.K. or E.U., or in the States of Illinois or New Jersey, which could discourage institutions and individuals from using our markets or products or encourage them to trade in another less costly jurisdiction. Legislation to impose a financial transaction tax has been proposed in the U.S. Congress, Illinois General Assembly and State of New Jersey Legislature in the last legislative sessions and could be proposed again in the current legislative sessions. Additionally, from time to time, the proposed U.S. Presidential budget request has included a proposal to impose a user fee to fund all or a portion of the budget of the CFTC.

12

•Certain provisions in relation to the E.U. Regulations on Benchmarks came into effect on January 1, 2018, and prices and data provided by CME Group for use by E.U. supervised entities and use of those benchmarks may be impacted. On November 30, 2020, the European Commission, European Parliament and the Council agreed to postpone application of the rules on third country benchmarks until December 31, 2023. As a result, all prices and data provided by CME Group are available for use by E.U. supervised entities throughout the transition period until January 1, 2023, subject to entering into appropriate licensing arrangements where relevant. The implementation of legislation in the E.U. impacting how benchmark index prices are formed, including new requirements for price submitters, price aggregators and markets that list contracts that reference index prices.

•Concerns that European legislators will prohibit or restrict exclusive licenses for benchmark indexes, which might impact the profitability of several of our most popular contracts.

•The FCA has indicated that it will no longer require banks to participate in the LIBOR panel after December 31, 2021. The possibility exists that the FCA may find LIBOR to not be representative of the underlying short-term interest rate pricing or unfit for such purpose, and thus may unfavorably impact our ability to list our existing suite of Eurodollar futures and options products.

•The implementation of rules resulting in negative treatment of the liquidity profile of U.S. Treasury securities, including as qualifying liquidity resources, or any potential limitation on the use of U.S. Treasury securities as collateral could result in increased costs to us and our clearing firms.

•The implementation of the final phases of uncleared margin rules (UMR Phase 5 & 6) across jurisdictions and implications for customers' management of exposures.

Human Capital Management

At CME Group, we rely on our highly skilled and experienced global workforce to meet our business objectives. As of December 31, 2020, our global employee population consisted of approximately 4,370 staff, with 58% (approximately 2,550) of these employees working in the U.S. and the remaining 42% (approximately 1,820) working in our various non U.S. locations (Australia, Brazil, Canada, China, France, Germany, Hong Kong, India, Israel, Japan, Netherlands, Philippines, Singapore, South Korea, Sweden, Switzerland and the U.K.).

We recognize that fostering a diverse and inclusive global culture is critical to our business success. We provide our workforce with a compelling employee experience that allows us to attract, retain and develop industry-leading talent. We are continually seeking new ways to challenge, develop and support our employees. Select highlights of our employee experience include the following:

•We offer a wide range of benefits designed to support our employees’ health and well-being, retirement needs, and work/life balance.

•We provide a variety of avenues for employees to grow their expertise, including tuition assistance for continuing education, onsite professional development training courses, access to external seminars and technical skills training, as well as an integrated series of leadership development programs to prepare employees for each stage of their careers.

•Our competitive compensation programs align employee rewards with shareholder interests and emphasize our pay-for-performance philosophy.

•Our Employee Network Groups (ENGs) are essential to fostering an inclusive culture grounded in mutual respect. All employees are eligible to join our ENGs and employees are encouraged to form new ENGs that align with our shared mission and values, creating communities around professional and personal interests.

We conduct regular employee engagement surveys and we monitor our performance against specific voluntary turnover, open role placement and internal promotion metrics to understand where further workforce investments may be necessary. During fiscal year 2020, our performance against these metrics was:

•5.2% voluntary turnover

•34% of open roles filled with internal candidates

•8.9% of employees promoted

13

Diversity and Inclusion

At CME Group, we embrace an exchange of ideas driven by the rich diversity of our people, cultures and experiences. We know that when our employees bring their authentic selves to work each day, it makes our business and our culture that much stronger. Leveraging the collective mix of perspectives and insights that our individual backgrounds bring, we can continually provide our global clients with innovative products and solutions, strengthen our competitive advantage and best serve the communities in which we live and work.

We have anchored our commitment to diversity and inclusion by incorporating it into our corporate goals and our Chief Human Resources Officer provides our senior management and Board with regular updates. Our Diversity and Inclusion (D&I) Council is responsible for driving our corporate D&I strategy. Members of our management team and employees from across our global workforce serve on the council, representing a wide variety of backgrounds and perspectives.

ITEM 1A.    RISK FACTORS

In addition to the other information contained in this Annual Report on Form 10-K, you should carefully consider the factors discussed below, which are the risks we believe are material at this time. These risks could materially and adversely affect our business, financial condition and results of operations. These risks and uncertainties are not the only ones facing us. Additional risks and uncertainties not presently known to us or that we currently believe to be immaterial may also adversely affect our business.

RISKS RELATING TO OUR INDUSTRY

Our business is subject to the impact of global market, economic and political conditions that are beyond our control and that could significantly impact our business and make our financial results more volatile.

Our revenue is substantially derived from fees for transactions executed and cleared in our markets. The trading volumes in our markets are directly affected by domestic and international factors that are beyond our control, including:

•economic, political and geopolitical market conditions;

•legislative and regulatory changes, including any direct or indirect restrictions on or increased costs associated with trading in our markets or our clearing services;

•broad trends in the industry and financial markets;

•changes in price levels, trading volumes and volatility in the derivatives, cash and OTC markets and in their underlying markets;

•shifts in demand or supply in commodities underlying our products;

•competition;

•changes in government monetary policies, including central bank decisions related to quantitative easing and the U.S. Federal Reserve and other international banks' forecasted commitment to zero or near-zero interest rates;

•availability of capital to our market participants and their appetite for risk-taking;

•levels of assets under our customers' management;

•volatile weather patterns, droughts, natural disasters and other catastrophes;

•pandemics affecting our customer base or our ability to operate our markets; and

•consolidation or expansion in our customer base and within our industry.

15

Any one or more of these factors may contribute to reduced activity in our markets. Historically, periods of heightened uncertainty have tended to increase our trading volume due to increased hedging activity and the increased need to manage the risks associated with, or speculate on, volatility. However, as evidenced by our past performance, in the period after a material market disturbance, there may persist extreme uncertainties, which may lead to decreased volume due to factors such as reduced risk exposure, lower interest rates, central bank asset purchase programs and lack of available capital. The shifts in market trading patterns we experienced as a result of the financial crisis of 2008 may or may not recur in the future, and our business will be affected by future economic uncertainties, which may result in decreased trading volume and a more challenging business environment for us. We believe that our interest rate product line will continue to be negatively impacted by the current state of the economy and a zero-interest rate policy. A reduction in overall trading volume or in certain products could render our markets less attractive to market participants as a source of liquidity, which could result in further loss of trading volume and associated transaction-based revenue. Material decreases in trading volume would have a material adverse effect on our financial condition and operating results.

Please see "Item 1A - Risk Factors - Risks Relating To Our Business" beginning on page 19 for additional information.

We operate in a heavily regulated environment that imposes significant costs and competitive burdens on our business and our failure to maintain compliance with regulations, our status as a regulated entity, or BrokerTec Americas' status as a member in good standing at FICC, could result in the loss of customers.

We are primarily subject to the jurisdiction of the regulatory agencies in the U.S., U.K. and Europe. As a result of our global operations, we are also subject to the rules and regulations of other local jurisdictions in which we conduct business and offer our products and services, as appropriate.

Due to the global financial crisis that began in 2008, the U.S. and numerous other jurisdictions have undertaken reviews of the legal framework governing financial markets and have either enacted new laws, rules and regulations, or are in the process of enacting new laws, rules and regulations that could impact our business. We have incurred and expect to continue to incur significant costs to comply with the extensive regulations that apply to our business.

Additional new laws or regulations or changes in enforcement practices applicable to our businesses or those of our clients could be imposed in the U.S. or other jurisdictions, which could change, or require us to change, our business practices or the structure of our business, including its current governance structure, or impose significant costs on us by, for example, requiring more of our funds to be set aside for the guaranty fund. This could adversely affect our ability to compete effectively with other institutions that are not affected in the same way or impact our clients' overall trading volume and demand for our market data and other services. Additionally, regulations imposed on financial institutions or market participants generally may adversely impact their trading activity in our markets. To the extent the legislative and regulatory environment is less beneficial for us or our customers, our business, financial condition and operating results could be negatively affected.

Legislation may be proposed, both domestically and internationally, that could add a transaction tax on our products or change the way our market participants are taxed on the products they trade on our markets. If such proposals were to become law, they could have a negative impact on our industry and on us by making transactions more costly to market participants, which may reduce trading and could make our markets less competitive.

If we fail to comply with applicable laws, rules or regulations, we may be subject to censure, fines, cease-and-desist orders, suspension of our business, removal of personnel or other sanctions, including revocation of our designations as a contract market, derivatives clearing organization, swap execution facility, swap data repository or broker-dealer or other regulatory penalties.

Our broker-dealer and multilateral trading facility businesses, BrokerTec and EBS, are also extensively regulated in various jurisdictions. These regulatory obligations generally include proper licensing and qualification of the firms and individuals, substantive conduct standards, communication and disclosure rules, monitoring and surveillance, training, capital requirements, supervisory obligations, maintenance of anti-money laundering programs, suspicious activity reporting, risk management standards, trade reporting, and ongoing examinations and reviews. The risks from failing to comply with these regulatory obligations include potential liability, disciplinary action against the firm and individuals, monetary penalties, and restrictions on future activities.

BrokerTec Americas' matched principal platform facilitates anonymous trading in significant volumes from wholesale market participants, many of which are FICC members and understand that BrokerTec Americas is also a FICC member, such that their trades are expected to be novated promptly to FICC, which will be their ultimate counterparty. A failure of BrokerTec Americas to maintain its membership could adversely impact the willingness of such participants to continue trading on our platform. As part of maintaining its FICC membership, BrokerTec Americas is required to timely and fully meet all margin calls and other obligations established by FICC, and as such must maintain ready access to sufficient liquidity to satisfy those obligations. BrokerTec Americas maintains access to liquidity resources it believes will satisfy these obligations in normal and stressed circumstances, but there can be no guarantee it will never experience a shortfall.

Please see "Item 1 - Business - Regulatory Matters" beginning on page 11 for additional information on our areas of regulatory focus.

Some of CME Clearing's largest clearing firms have indicated their belief that clearing facilities should not be owned or controlled by exchanges and should be operated as utilities and not for profit. These clearing firms have sought, and may seek in the future, legislative or regulatory changes that would, if adopted, enable them to use alternative clearing services for positions established on our exchanges or to freely move open positions among clearing houses in order to take advantage of our liquidity. Even if they are not successful, these factors may cause them to limit the use of our markets.

Our clearing house seeks to offer customers, intermediaries and clearing firms universal access in order to maximize the efficient use of capital, exercise appropriate oversight of value at risk and maintain operating leverage from clearing activities on our exchanges. Our strategic business plan for our futures and options business is to operate an efficient and transparent vertically integrated transaction execution, clearing and settlement business. Some of our clearing firms have expressed the view that clearing firms should control the governance of clearing houses or that clearing houses should be operated as utilities rather than as part of for-profit enterprises. Some of these firms, along with certain industry associations, have sought, and may seek in the future, legislative or regulatory changes to be adopted that would facilitate mechanisms or policies that allow market participants to transfer positions of futures or options from an exchange-owned clearing house to a clearing house owned and controlled by clearing firms. If these legislative or regulatory changes are adopted, our revenues and profits could be adversely affected.

We face intense competition from other companies. If we are not able to successfully compete, our business, financial condition and operating results will be materially harmed.

The industry in which we operate is highly competitive and we expect competition to continue to intensify. We encounter competition in all aspects of our business, including from entities having substantially greater capital and resources, offering a wide range of products and services and in some cases operating under a different and possibly less stringent regulatory regime. We face competition from other futures, securities and securities option exchanges; OTC markets; clearing organizations; consortia formed by our members and large industry participants; swap execution facilities; alternative trade execution facilities; technology firms, including market data distributors and electronic trading system developers, and others. Our competitors and potential competitors may have greater financial, marketing, technological and personnel resources than we do.

Our competitors may:

•respond more quickly to competitive pressures, including responses based upon their corporate governance structures, which may be more flexible and efficient than our corporate governance structure;

•develop products that are preferred by our customers compared to those offered by CME Group;

•develop risk transfer products that compete with our products;

•price their products and services more competitively;

•develop and expand their network infrastructure and service offerings more efficiently;

•utilize better, more user-friendly or more reliable technology;

•take greater advantage of acquisitions, alliances and other opportunities that provide a competitive advantage;

•more effectively market, promote and sell their products and services;

•better leverage existing relationships with customers and alliance partners or exploit better recognized brand names to market and sell their services; or

•exploit regulatory disparities between traditional, regulated exchanges and alternative markets that benefit from a reduced regulatory burden and lower-cost business model.

If our products, markets and services are not competitive, our business, financial condition and operating results could be adversely affected. A decline in our fees or loss of customers could lower our revenues, which would adversely affect our profitability.

Please see "Item 1 - Business - Competition" beginning on page 10 for additional information on the competitive environment and its potential impact on our business.

Our trading volume, and consequently our revenues and profits, would be adversely affected if we are unable to retain our current customers at substantially similar trading levels or attract new customers.

The success of our business depends, in part, on our ability to maintain and increase trading volume in our markets. To do so, we must maintain and expand our product offerings, our customer base and our trade execution facilities, our pre-and post-trade

17

services and clearing facilities. Our success also depends on our ability to offer competitive prices and services in an increasingly price-sensitive business. For example, some of our competitors have engaged in aggressive pricing strategies in the past, such as lowering the fees they charge for taking liquidity and increasing liquidity payments or rebates. We cannot provide assurances that we will be able to continue to expand our products and services, that we will be able to retain our current customers or attract new customers or that we will not be required to modify our pricing structure to compete effectively. Changes in our pricing structure may result in a decrease in our profit margin.

Our clearing firm clients must meet certain capital requirements and must deposit collateral to meet performance bond and guaranty fund requirements. There is no guarantee the collateral deposited will continue to maintain its value. To the extent a clearing firm were to experience a decrease in capital and be unable to meet requirements, it may be required to decrease its trading activity.

Additionally, from time to time, certain customers may represent a significant portion of the open interest in our individual product lines or contracts and a substantial decrease in their trading activity could have a negative impact on the liquidity of the particular product line or contract.

If we fail to maintain trading volume, as a result of a loss of customers or decrease in trading activity; expand our product offerings or execution facilities; or are unable to attract new customers, our business and revenues will be adversely affected. Declines in trading volume may also negatively impact market liquidity, which could lead to further loss of trading volume. Because our cost structure is largely fixed, if demand for our products and services and our resulting revenues decline, we may not be able to adjust our cost structure on a timely basis and our profitability could be adversely affected.

Our role in the global marketplace places us at greater risk than other public companies for a cyber attack and other cyber security risks. Our technology, our people and those of our third-party service providers may be vulnerable to cyber security threats, which could result in wrongful use of our data or our customers’ data or cause interruptions in our operations that cause us to lose customers and trading volume and result in substantial liabilities. We also could be required to incur significant expense to protect our systems and/or investigate any alleged attack.

We regard the secure storage and transmission of data and the ability to continuously transact and clear on our electronic trading platforms as critical elements of our operations. Our technology, our people and those of our third-party service providers and our customers may be vulnerable to targeted attacks, such as "phishing" attacks, unauthorized access, fraud, computer viruses, denial of service attacks, terrorism, "ransom" attacks, firewall or encryption failures or other security risks. Criminal groups, political activist groups and nation-state actors have targeted the financial services industry in general, and our role in the global marketplace places us at greater risk than other public companies for a cyber attack and other information security threats. While we have not experienced cyber incidents that are individually, or in the aggregate, material, we have experienced cyber attacks of varying degrees in the past. Our usage of mobile and cloud technologies may increase our risk for a cyber attack. Our security defenses may also be impacted or breached due to employee error, malfeasance, system errors or vulnerabilities. Additionally, outside parties may attempt to fraudulently induce employees, users, or customers to disclose sensitive information in order to gain access to our technology systems and data, or our customers’ data. Any such breach or unauthorized access could result in significant legal and financial exposure, damage to our reputation, and a loss of confidence in the services we provide that could potentially have an adverse effect on our business, while resulting in regulatory penalties or the imposition of additional obligations by regulators or others. As the regulatory environment related to information security, data collection and use, and privacy becomes increasingly rigorous and complex, any failure to comply may carry significant penalties and reputational damage.

We have designed our cyber defense program to mitigate such attacks and security risks through administrative, physical and technical safeguards. As part of our global information security and privacy programs, we employ resources to prevent, detect and respond to cyber-attacks and security risks that could impact our people, processes, and technology infrastructure, including the rapid response to zero-day vulnerabilities. However, our security measures or those of our third-party providers, including any cloud-based technologies, may prove insufficient depending upon the attack or threat posed. Any security attack or breach could result in system failures and delays, malfunctions in our operations, loss of customers or lower trading volume, loss of competitive position, damage to our reputation, disruption of our business, legal liability or regulatory fines and significant costs, which in turn, may cause our revenues and earnings to decline. Though we have insurance against some cyber and privacy risks and attacks, we may be subject to litigation and financial losses that exceed our policy limits or are not covered under any of our current insurance policies.

As a financial services provider, we are subject to significant litigation risk and regulatory liability and penalties.

Many aspects of our business present substantial litigation risks. These risks include, among others, potential liability from disputes over terms of a trade, the claim that a system failure or delay caused monetary losses to a customer, that we entered into an unauthorized transaction, that we provided materially false or misleading statements in connection with a transaction or that we failed to effectively fulfill our regulatory oversight responsibilities. We may be subject to disputes regarding the quality of trade execution, the settlement of trades or other matters relating to our services. We may become subject to these claims as a

18

result of failures or malfunctions of our systems and services we provide. We could incur significant legal expenses defending claims, even those without merit. In addition, an adverse resolution of any future lawsuit or claim against us could have a material adverse effect on our business and our reputation. To the extent we are found to have failed to fulfill our regulatory obligations, we could lose our authorizations or licenses or become subject to conditions that could make future operations more costly and impair our profitability. Such events could also result in customer dissatisfaction and a decline in their willingness to trade on our markets.

We may be at greater risk from terrorism, which poses physical security risks and cyber-security risks, than other companies.

Given our role in the global financial services industry, we may be more likely than other companies to be a direct target of, or an indirect casualty of, attacks by terrorists or terrorist organizations. It is impossible to accurately predict the likelihood or impact of any terrorist attack on our industry generally or on our business. While we have implemented significant physical security protection measures, business continuity plans and established backup sites, in the event of an attack or a threat of an attack, these security measures and contingency plans may be inadequate to prevent significant disruptions in our business, technology or access to the infrastructure necessary to maintain our business. Such an attack may result in harm to our personnel, the closure of our facilities or render our backup data and recovery systems inoperable. Damage to our facilities due to terrorist attacks may be significantly in excess of any amount of insurance coverage available, or we may not be able to insure against such damage at a reasonable price or at all. The threat of terrorist attacks also may negatively affect our ability to attract and retain employees. Any of these events could have a material adverse effect on our business, financial condition and operating results.

RISKS RELATING TO OUR BUSINESS

The COVID-19 pandemic has negatively affected the global economy, including the U.S. economy and the global financial markets, and has disrupted our business and that of our clients’ businesses. The ultimate impact from COVID-19, including duration, is unknown and could have an adverse effect on our business, financial condition and results of operations.

The ongoing COVID-19 health emergency has caused significant disruption in the international and U.S. economies and financial markets. The spread of COVID-19 has caused illness, quarantines, cancellation of events and travel, business and school shutdowns, reduction in business activity and financial transactions, labor shortages, supply chain interruptions and overall economic and financial market instability in the U.S. Similar impacts also have been experienced throughout the world, including in every country in which we do business. Given the unique and unpredictable nature of this event, future impacts to our business are unknown and could be material. Those impacts may include, among others, the following:

•Continued disruption to our business and operations;

•Key members of senior management or a significant number of our employees unable to work as a result of contracting COVID-19 or related illnesses;

•Reduced productivity and operating effectiveness as a result of our employees working remotely and impacts on our clients encountering similar circumstances;

•Impacts on our third-party suppliers and their ability to fulfill their obligations to us;

•Decreased trading volume and unprecedented market stresses in global financial markets;

•Changes in demand for our products and services, based upon fiscal, monetary and trade policies adopted in response to the economic impact of the pandemic;

•Reduced economic activity generally could cause businesses to have less need to hedge in our markets;

•Delays in our expansion, investment and strategic initiatives and system integrations;

•Impacts to our ability to expand our client base, grow our business and generate new revenue due to the inability to hold in-person meetings, events and conferences and other impacts from social distancing;

•Impacts on our brand and reputation due to negative investor sentiment in the overall financial markets;

•Increased financial and operational stress experienced by our clearing firm members due to unprecedented volatility, including significant losses that may result in a reduction of business or a default;

•Market access or trading limitations imposed by governmental authorities; and

•Increased technology and cyber-security risks, social engineering and phishing campaigns.

These potential impacts may exist for a significant period of time and may adversely affect our business, financial condition and results of operations even after the COVID-19 pandemic has subsided.

19

In the past year, we have experienced an overall decrease in trading volume, which we believe is in part a result of effects of the COVID-19 pandemic. Additionally, the spread of COVID-19 has caused us to modify our business practices, including restricting employee travel and continuing work-from-home protocols, and we may take further actions as may be required by government authorities or as we determine to be in the best interests of our employees and clients. We also closed our open outcry trading floor and trading is now conducted almost entirely through our electronic trading system. In August 2020, the Eurodollar options pit was reopened after being reconfigured to meet social distancing standards with additional safety standards in place. There is no certainty that such measures will be sufficient to mitigate the risks posed by the virus or will otherwise be satisfactory to government authorities.

The extent to which the COVID-19 pandemic further impacts our business, results of operations or financial condition will depend on future developments, which are highly uncertain and difficult to predict, but may include, among others, the duration and spread of the pandemic, its severity, the actions taken by governments and other third parties to contain the virus or treat its impact, such as vaccination, and the effect of such actions on our business practices (including ending work-from-home protocols), the impact of existing and any future federal stimulus measures, and the pace at which, and the extent to which, normal economic and operating conditions resume, or even if they resume, whether such economic and operating conditions can be sustained.

In addition, many of the other risk factors described herein could be heightened by the effects of the COVID-19 pandemic and related economic conditions, which could result in a material impact on our results of operations, financial condition and liquidity.

Damage to our reputation could harm our business.

Maintaining our reputation and brand is critical to attracting and retaining customers and investors and to maintaining our relationships with our regulators. Negative publicity regarding our company or actual, alleged or perceived issues regarding our products or services, including social and environmental concerns relating to certain commodity products and increased impact from climate change or criticism or market reaction to the performance of our market in periods of extreme volatility, could give rise to reputational risk which could significantly harm our business prospects. These issues may include, but are not limited to, any of the risks discussed in this Item 1A, including risks from customer disputes, system failures or intrusions, failures to meet our regulatory obligations, failures of a clearing firm or other counterparty, issues relating to our third-party suppliers, alleged or actual fraud or misconduct or manipulative activity, or ineffective risk management.

The success of our markets depends on our ability to complete development of, successfully implement and maintain the electronic trading and clearing systems that have the functionality, performance, availability, capacity, security and speed required by our customers.

The success of our business depends in large part on our ability to create interactive electronic marketplaces, for a wide range of products, that have the required functionality, performance, availability, capacity, security and speed to attract and retain customers. In 2020, 94% of our overall contract volume was generated through electronic trading on our CME Globex electronic platform and we generated $352.5 million in revenue attributable to the BrokerTec and EBS trading platforms.

We must continue to enhance our electronic trading platforms and other technology offerings to remain competitive. As a result, we will continue to be subject to risks, expenses and uncertainties encountered in the rapidly evolving market for electronic transaction services. These risks include our failure or inability to:

•provide reliable and cost-effective services to our customers;

•develop, in a timely manner, the required functionality to support electronic trading in a manner that is competitive with the functionality supported by other electronic markets;

•maintain the competitiveness of our fee structure;

•attract independent software vendors to write front-end software that will effectively access our electronic trading systems and automated order routing system;

•respond to technological developments or service offerings by competitors; and

•generate sufficient revenue to justify the substantial capital investment we have made and will continue to make to enhance our electronic trading platforms and other technology offerings.

If we do not successfully enhance our electronic trading systems and technology offerings, if we are unable to develop them to include other products and markets, or if they do not have the required functionality, performance, availability, capacity, security and speed desired by our customers, our ability to successfully compete and our revenues and profits will be adversely affected. Although we are focused on the technology and customer experience as part of the migration of the BrokerTec platform to CME Globex in the first quarter of 2021 and the expected migration of the EBS platform to CME Globex in the

20

fourth quarter of 2021, we cannot guarantee that we will not experience any client attrition and to the extent any such client attrition is significant, it could have an impact on our revenues.

Additionally, we rely on our customers' ability to have the necessary back office functionality to support our new products and our trading and clearing functionality. To the extent our customers are not prepared and/or lack the resources or infrastructure, the success of our new initiatives may be compromised.

If we experience systems failures or capacity constraints, our ability to conduct our operations and execute our business strategy could be materially harmed and we could be subjected to significant costs and liabilities.

Our business is highly dependent on our ability to process, execute and monitor, in an efficient and uninterrupted manner, a large number of transactions which occur at high volumes and frequencies across multiple systems and our ability to access key business data, financial information, order processing and invoicing. We are heavily reliant on the capacity, reliability and security of our information technology and communications and other business systems and software supporting our operations. Our systems, or those of our third-party providers, including cloud providers, may fail or be shut down or, due to capacity constraints, may operate slowly, causing one or more of the following to occur:

•unanticipated disruptions in service to our customers;

•slower response times and delays in our customers' trade execution and processing;

•failed settlement of trades;

•incomplete or inaccurate accounting, recording or processing of trades;

•financial losses;

•security breaches;

•litigation or other customer claims;

•loss of customers; or

•regulatory sanctions.

We cannot assure that we will not experience systems failures from power or telecommunications failures, acts of God, war or terrorism, human error on our part or on the part of our vendors, natural disasters, fire, sabotage, hardware or software malfunctions or defects, computer viruses, cyber attacks, acts of vandalism or similar occurrences. If any of our systems or the systems of our third-party providers do not operate properly, are compromised or are disabled, including as a result of system failure, employee or customer error or misuse of our systems, we could suffer financial loss, liability to customers, regulatory intervention or reputational damage that could affect demand by current and potential users of our market.

From time to time, we have experienced system errors and failures that have resulted in some customers being unable to connect to our electronic trading platforms and technology offerings, or that resulted in erroneous reporting, such as transactions that were not authorized by any customer or reporting of filled orders as canceled. Such errors may result in CME Group being liable or in our voluntary assumption of financial liability. We cannot assure that if we experience system errors or failures in the future that they will not have a material adverse impact on our business. Any such system failures that cause an interruption in service or decrease our responsiveness could impact our trading volumes, impair our reputation, damage our brand, result in regulatory fines and have a material adverse effect on our business, financial condition and operating results.

Regulations relating to our trading and clearing systems generally require the handling of anticipated present and future peak trading volume. Heavy use of our systems during peak trading times or at times of unusual market volatility could cause them to operate slowly or even to fail for periods of time. We constantly monitor system loads and performance, and regularly implement system upgrades to handle estimated increases in volume. However, we cannot assure that our estimates of future trading volume and order messaging traffic will be accurate or that our systems will always be able to accommodate actual trading volume and order messaging traffic without failure or degradation of performance. Increased trading volume and order messaging traffic may result in connectivity problems or erroneous reports that may affect users of our platforms. System failure or degradation could lead our customers to file formal complaints with industry regulatory organizations, to file lawsuits against us or to cease doing business with us or could lead our regulators to initiate inquiries or proceedings for failure to comply with applicable laws and regulations.

We will need to continue to upgrade, expand and increase the capacity of our systems as our business grows and as we execute our business strategy. Although many of our systems are designed to accommodate additional volume and products and services without redesign or replacement, we will need to continue to make significant investments in additional hardware and software to accommodate the increases in volume of transactions and order transaction traffic and to provide processing services to third parties. If we cannot increase the capacity and capabilities of our systems to accommodate an increasing

21

volume of transactions and to execute our business strategy, our ability to maintain or expand our businesses could be adversely affected.

We, as well as many of our customers, depend on third-party suppliers and service providers for a number of services that are important. An interruption or cessation of an important supply or service by any third party could have a material adverse effect on our business, including revenues derived from our customers' trading activity.

We depend on a number of suppliers, such as banking, clearing and settlement organizations, telephone companies, internet service providers, data processors, cloud hosting providers, data center providers, and software and hardware vendors, for elements of our trading, clearing and other systems, as well as communications and networking equipment, computer hardware and software and related support and maintenance.

Many of our customers rely on third parties, such as independent software vendors, to provide them with front-end systems to access our trading platforms and other back office systems for their trade processing and risk management needs. While these service providers have undertaken to keep current with our enhancements and changes to our interfaces and functionality, we cannot guarantee that they will continue to make the necessary monetary and time investments to keep up with our changes.

To the extent any of our service providers or the organizations that provide services to our customers in connection with their trading activities cease to provide these services or provide these services in an efficient, cost-effective manner or fail to adequately expand their services to meet our needs and the needs of our customers, we could experience decreased trading volume, lower revenues and higher costs.

Our business exposes us to substantial credit risk of our clearing firms and other counterparties and, consequently, a decrease in their financial resources could adversely affect us.

Our clearing house operations expose us to counterparties with differing risk profiles. We routinely guarantee transactions submitted by our clearing firm customers with counterparties in the financial industry, including brokers and dealers, commercial banks, investment banks, mutual and hedge funds, and other institutional customers. We could be adversely impacted by the financial distress or failure of one or more of our clearing firms. Additionally, we are exposed to the risk of loss from the failure of a matched principal counterparty to settle its trades at BrokerTec Americas.

A substantial part of our working capital may be at risk if a clearing firm defaults on its obligations to our clearing house and its margin and guaranty fund deposits are insufficient to meet its obligations. Additionally, BrokerTec Americas is exposed to the potential risk of loss in the event a counterparty fails to meet its obligations. Although we have policies and procedures to help ensure that our clearing firms and other counterparties can satisfy their obligations, these policies and procedures may not succeed in detecting problems or preventing defaults. We also have in place various measures intended to enable us to cure any default and maintain liquidity. However, we cannot guarantee that these measures will be sufficient to protect market participants from a default or that we will not be adversely affected in the event of a significant default. In addition, we have established a fund (currently $98.0 million) to provide payments, up to certain maximum levels, to qualified family farmers, ranchers and other agricultural industry participants who use our products and who suffer losses to their segregated account balances if their clearing firm becomes insolvent.

Our Three-Month Eurodollar futures contracts are based on the three-month U.S. Dollar London Interbank Offered Rate (LIBOR) underlying rate. To the extent trading in Eurodollar contracts decreases or is discontinued and our alternative contracts are not successful, our revenues would be negatively impacted. Certain of our other businesses could also be negatively affected by changes to LIBOR.

Our Eurodollar futures contract is based on the three-month U.S. Dollar ICE LIBOR underlying rate. In 2020, average trading volume in our Eurodollar contracts was 3.1 million contracts and open interest was 32.4 million contracts. LIBOR is the subject of national and international proposals for reform which advocate for the transition of survey based interbank offered rates to alternative transaction-based reference rates. A transition from the widespread use of LIBOR to alternative benchmark rates is likely to occur over the next several years. The U.K. FCA, which regulates LIBOR, has announced the desire to phase out the use of LIBOR by the end of 2021. The U.S. Federal Reserve, in conjunction with the Alternative Reference Rates Committee, a steering committee comprised of large U.S. financial institutions, has recommended replacing U.S. Dollar LIBOR with other benchmark alternatives, such as SOFR. It is unknown whether these alternative reference rates will attain market acceptance as replacements for LIBOR. In October 2020, central banking counterparties revised the discounting and price alignment interest (PAI) of U.S.-dollar cleared interest rate swaps to use SOFR. This event affected interest rate swaps, including auctions of newly created SOFR basis swaps, and increased liquidity for SOFR and the resulting orderly auctions.

On November 30, 2020, ICE Benchmark Administration (IBA) announced a consultation on its intention to cease the publication of certain LIBOR rates, including its intention to cease the publication of the three-month U.S. Dollar LIBOR on June 30, 2023. The U.K. FCA also announced its proposed approach to ensure an orderly wind-down of LIBOR and has supported publication of three-month U.S. Dollar LIBOR tenor in a representative manner through June 30, 2023. The U.S. Federal Reserve, Office of Comptroller of the Currency and the Federal Deposit Insurance Company also issued a statement

22

encouraging banks to cease entering into new contracts that use U.S. Dollar LIBOR as a reference rate as soon as practicable and in any event by December 31, 2021.

Any transition away from LIBOR to alternative reference rates is complex and could have a material adverse effect on our business, financial condition and results of operations. We have closely engaged with the industry, regulators and market participants to launch products using alternative reference rates, including our SOFR and Sterling Overnight Index Average (SONIA) futures contracts. While these actions have resulted in an increase in market acceptance of SOFR, there is no guarantee that this transition will be successful or replace the revenue we derive from our Eurodollar contracts if trading volume were to decline or discontinue altogether.

Our market data revenues may be reduced by decreased demand, poor overall economic conditions, regulatory changes or a significant change in how market participants trade and use market data.

We offer a wide range of data services designed to support the trading, risk management, investment and business needs of our global customer base. Revenues from our market data and information services represented 11% of our total revenues during the years ended December 31, 2020 and December 31, 2019, respectively. Factors that may affect our performance and demand for our data include, but are not limited to:

•Our ability to maintain existing customers utilizing our data and to attract new customers with our products and services;

•A decrease in overall trading volume, which may lead to a decreased demand for our market data;

•A challenging business environment for our customers, which may require them to reduce their usage of our market data;

•The impacts of new regulations, laws, rules or other government policies;

•Our ability to ensure that customers are appropriately licensed and are paying fees for the data used;

•The protection of our intellectual property rights and identification of misappropriation and/or misuses of CME Group market data; and

•Our ability to keep pace with technological developments and client preferences.

We may have difficulty executing our growth strategy and maintaining our growth effectively.

We continue to focus on strategic initiatives to grow our business, including our efforts to serve the OTC markets and to distribute our products and services on a global basis. There is no guarantee that our efforts will be successful. Continued growth will require additional investment in personnel, facilities, information technology infrastructure, and financial and management systems and controls and may place a significant strain on our management and resources. For example, if we encounter limited resources, we may be required to increase our expenses to obtain the necessary resources, defer existing initiatives or not pursue certain opportunities. We may not be successful in implementing all of the processes that are necessary to support our growth organically or, as described below, through acquisitions, other investments or strategic alliances. Our growth strategy also may subject us to increased legal, compliance and regulatory obligations. Unless our growth results in an increase in our revenues that is proportionate to the increase in our costs associated with our growth, our future profitability could be adversely affected, and we may have to incur significant expenditures to address the additional operational and control requirements as a result of our growth.

We intend to continue to explore acquisitions, other investments and strategic alliances. We may not be successful in identifying opportunities or in integrating the acquired businesses. Any such transaction may not produce the results we anticipate, which could adversely affect our business and our stock price.

We intend to continue to explore and pursue acquisitions and other strategic opportunities to strengthen our business and grow our company. We may make acquisitions or investments or enter into strategic partnerships, joint ventures and other alliances. The market for such transactions is highly competitive, especially in light of historical merger and acquisition activity in our industry. As a result, we may be unable to identify strategic opportunities or we may be unable to negotiate or finance future transactions on terms favorable to us, which could impact our ability to identify growth opportunities. We may finance future transactions by issuing additional equity and/or debt. The issuance of additional equity in connection with any future transaction could be substantially dilutive to our existing shareholders. The issuance of additional debt could increase our leverage substantially.

The process of integration also may produce unforeseen regulatory and operating difficulties and expenditures and may divert the attention of management from the ongoing operation of our business. To the extent we enter into joint ventures and alliances, we may experience difficulties in the development and expansion of the business of any newly formed ventures, in the exercise of influence over the activities of any ventures in which we do not have a controlling interest, as well as encounter

23

potential conflicts with our joint venture or alliance partners. We may not realize the anticipated growth and other benefits from our growth initiatives and investments, which may have an adverse impact on our financial condition and operating results. We also may be required to take an impairment charge in our financial statements relating to our acquisitions and/or investments, which could negatively affect our stock price. Our acquisition of NEX is subject to many of these risks, including the potential we may not achieve the expected cost savings, synergies and other strategic benefits from the transaction within the anticipated time frames and the integration of NEX with our operations may not be successful or may be delayed or more costly than expected, or that we may experience customer attrition.

The expansion of our global operations is complex and subjects us to increased business and economic risks that could adversely affect our financial results.

In connection with our expanded global operations, we face certain risks inherent in doing business internationally. These risks include:

•fluctuations in currency exchange rates;

•complying with extensive and complex regulations and oversight;

•difficulties in staffing and associated costs in managing multiple international locations;

•general economic, social and political conditions;

•protectionist laws and business practices that favor local businesses in some countries;

•reduced protection for intellectual property rights in some countries;

•language and cultural differences; and

•potentially adverse tax consequences.

If we are unable to manage the complexity of our global operations successfully, or if the risks above become substantial for us, our financial performance and operating results could suffer. Further, any measures we may implement to reduce risks of our international operations may not be effective, may increase our expenses and may require significant management time and effort.

As our consolidated financial statements are presented in U.S. dollars, we must translate our foreign subsidiaries’ financial statements from local currencies into U.S. dollars at exchange rates in effect during or at the end of each reporting period. Therefore, any increases or decreases in the value of the U.S. dollar against the other currencies may affect our operating income and the value of balance sheet items denominated in foreign currencies.

The Brexit transition period between the U.K. and E.U. ended in December 2020 and the E.U.-U.K. Trade and Cooperation Agreement provisionally entered into force on January 1, 2021. As a result of Brexit, we have established certain CME Group businesses in Amsterdam, an E.U. jurisdiction, which allows these businesses to continue offering products and services to customers in the E.U.; however, this has resulted in, and may continue to result in, increased legal, compliance and operational costs.

Our risk management and compliance programs might not be effective and may result in outcomes that could adversely affect our reputation, financial condition and operating results.

In the normal course of our business, we discuss matters with our regulators including during regulatory examinations, and we are subject to their inquiry and oversight. Our regulators have broad enforcement and supervisory powers, including the power to censure, fine, issue cease-and-desist orders, prohibit us from engaging in some of our businesses or suspend or revoke our regulatory designations or the registration of our officers or employees who violate applicable laws or regulations. Our ability to manage our risks and comply with applicable laws and regulations in the jurisdictions where we operate is largely dependent on our establishment and maintenance of effective risk management, compliance and monitoring programs. In the case of alleged non-compliance with applicable laws or regulations, we could be subject to investigations and judicial or administrative proceedings that may result in substantial penalties or civil lawsuits, including by customers, for damages, which could be significant. Any of these outcomes may adversely affect our reputation, financial condition and operating results. In extreme cases, these outcomes could adversely affect our ability to conduct our business.

We maintain risk management and compliance policies, procedures and programs which are designed to prevent, detect, deter, monitor and manage our risks, but such policies, procedures and programs may not be fully effective. Some of our risk management processes depend upon evaluation of information regarding markets, customers, employees or other matters or potential threats that are publicly available or otherwise accessible by us. That information may not in all cases be accurate, complete, up-to-date or properly evaluated. Management of operational, financial, legal and compliance, regulatory, reputational and strategic risk requires, among other things, policies and procedures to record properly and verify a large

24

number of transactions and events. We cannot guarantee that our policies and procedures will always be effective or that we will always be successful in monitoring or evaluating the risks to which we are or may be exposed.

We could be harmed by misconduct or errors that are difficult to detect and deter.

There have been a number of highly publicized cases involving fraud or other misconduct or manipulative activity by employees of financial services firms and other market participants in the past. Improper trading activity on our platforms by participants could include activities such as spoofing, layering, wash trading and manipulation. Misconduct by our employees and agents could include hiding unauthorized activities from us, improper or unauthorized activities on behalf of customers or the company, or improper use or unauthorized disclosure of data or confidential information of the company or its customers.

It is not always possible to deter misconduct, and the precautions we take to prevent and detect this activity may not be effective in all cases. If we were found to have not met our regulatory oversight and compliance obligations, we could be subject to regulatory sanctions, financial penalties, restrictions on our activities for failure to properly identify, monitor and respond to potentially problematic activity and seriously harm our reputation. Our employees and agents also may commit errors that could subject us to financial claims for negligence, as well as regulatory actions, or result in our voluntary assumption of financial liability. Further, allegations by regulatory or criminal authorities of improper trading activities could affect our brand and reputation and reduce the number of participants trading in our markets. If that should occur, we could face a corresponding decline in trading volume and revenue.

Intellectual property rights licensed from third-party price reporting agencies form the basis for many of our products from which we derive a significant portion of our volume and revenue. Material changes in the intellectual property landscape or regulatory framework pertaining to such benchmarks could have a negative impact on our ability to offer such products.

We are significantly dependent on the contract volume of products which are based on intellectual property rights of indexes derived from third-party price reporting agencies. To comply with CFTC core principles, we must be able to demonstrate that our products may not be readily susceptible to manipulation. Our inability to offer products based on these indexes could have a negative impact on our contract volume and revenues.

A failure to protect our intellectual property rights, or allegations that we have infringed the intellectual property rights of others, could adversely affect our business.

Our business is dependent on proprietary technology and other intellectual property that we own or license from third parties. We own the rights to a large number of trademarks, service marks, domain names and trade names in the U.S., Europe and other parts of the world. We have registered many of our most important trademarks in the U.S. and other countries. We hold the rights to a number of patents and have patent applications pending. Our patents cover match engine, trader user interface, trading floor support, market data, general technology and clearing house functionalities. We attempt to protect our proprietary technology and intellectual property rights by relying on trademarks, copyright, database rights, trade secrets, restrictions on disclosure and other methods. Notwithstanding the precautions we take to protect our proprietary technology and intellectual property rights, it is possible that third parties may copy, misappropriate or otherwise obtain and use our proprietary technology without authorization or otherwise infringe on our rights. For example, one of our former employees pleaded guilty to theft of our trade secrets. In addition, in the future, we may have to rely on litigation to enforce our intellectual property rights, protect our trade secrets, determine the validity and scope of the proprietary rights of others or defend against claims of infringement or invalidity. Any such litigation, whether successful or unsuccessful, could result in substantial costs to us and diversions of our resources, either of which could adversely affect our business.

Patents of third parties may have an important bearing on our ability to offer certain products and services. Our competitors as well as other companies and individuals may obtain, and may be expected to obtain in the future, patents related to the types of products and services we offer or plan to offer. We cannot guarantee that we are or will be aware of all patents containing claims that may pose a risk of infringement by our products and services. In addition, some patent applications in the U.S. are confidential until a patent is issued and, therefore, we cannot evaluate the extent to which our products and services may be covered or asserted to be covered by claims contained in pending patent applications. These claims of infringement are not uncommon in our industry. As a result, we may face allegations that we have infringed the intellectual property rights of third parties, which may be costly for us to defend against. If one or more of our products or services is found to infringe on patents held by others, we may be required to stop developing or marketing the products or services, to obtain licenses to develop and market the services from the holders of the patents or to redesign the products or services in such a way as to avoid infringing on the patents. We could also be required to pay damages if we were found to infringe patents held by others, which could materially adversely affect our business, financial condition and operating results. We cannot assess the extent to which we may be required in the future to obtain licenses with respect to patents held by others, whether such licenses would be available or, if available, whether we would be able to obtain such licenses on commercially reasonable terms. If we were unable to obtain such licenses, we may not be able to redesign our products or services at a reasonable cost to avoid infringement, which could materially adversely affect our business, financial condition and operating results.

RISKS RELATING TO AN INVESTMENT IN OUR CLASS A COMMON STOCK

Our indebtedness could adversely affect our financial condition and operations and prevent us from fulfilling our debt service obligations. We might still be able to incur more debt, intensifying these risks.

As of December 31, 2020, we had approximately $3.4 billion of total indebtedness and we had excess borrowing capacity for general corporate purposes under our existing facilities of approximately $2.4 billion.

Our indebtedness could have important consequences. For example, our indebtedness may:

•require us to dedicate a significant portion of our cash flow from operations to payments on our debt, thereby reducing the availability of cash flows to fund capital expenditures, to pursue acquisitions or investments, to pay dividends and for general corporate purposes;

•increase our vulnerability to general adverse economic conditions;

•limit our flexibility in planning for, or reacting to, changes in or challenges relating to our business and industry; or

•place us at a competitive disadvantage against any less leveraged competitors.

The occurrence of any one of these events could have a material adverse effect on our business, financial condition, results of operations, prospects and ability to satisfy our debt service obligations. In addition, the agreements governing our outstanding indebtedness do not significantly limit our ability to incur additional indebtedness, which could increase the risks described above to the extent that we incur additional debt. Our U.S. exchanges, swap execution facility and clearing house also are required to maintain minimum capital levels as defined by the CFTC, and BrokerTec Americas is required to meet minimum capital requirements set by the SEC.

Any reduction in our credit rating could increase the cost of our funding from the capital markets.

Our long-term debt is currently rated investment grade by two of the major rating agencies. These rating agencies regularly evaluate us. Their ratings of our long-term debt are based on a number of factors, including our financial strength, as well as factors not entirely within our control, such as conditions affecting the financial services industry generally. In light of the difficulties in the financial services industry and the financial markets over the last few years, including in connection with the global pandemic, there can be no assurance that we will maintain our current ratings. In the past, we have experienced ratings downgrades. Our failure to maintain our ratings could adversely affect the cost and other terms upon which we are able to obtain funding and increase our cost of capital. Additionally, if our ratings are downgraded below investment grade due to a change of control, we are required to make an offer to repurchase all of our fixed-rate notes at a price equal to 101% of the principal amount, plus accrued and unpaid interest.

Our average rate per contract for our derivatives business is subject to fluctuation due to a number of factors. As a result, our average rate per contract in any particular period may not be a reliable indication of our future average rate per contract.

Our average rate per contract for our derivatives business, which impacts our operating results, is subject to fluctuation due to shifts in the mix of 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. In addition, our members and participants in our various incentive programs generally are charged lower fees than our non-member customers. Variation in each of these factors is difficult to predict and will have an impact on our average rate per contract in the particular period. Because of this fluctuation, we cannot assure that our average rate per contract in any particular period serves as an indication of our future average rate per contract. If we fail to meet securities analysts' expectations regarding our operating results, the price of our Class A common stock could decline substantially.

Eleven of our board members own trading rights or are officers or directors of firms that own trading rights on our derivatives exchanges. As members, these individuals may have interests that differ from or conflict with those of shareholders who are not also members. Our dependence on the trading and clearing activities of our exchange members, combined with the CME members' rights to elect six directors, may enable them to exert substantial influence over the operation of our business.

Eleven of our directors own or are officers or directors of firms that own trading rights on our exchanges. We are dependent on the revenues from the trading and clearing activities of our exchange members. In 2020, 83% of our derivatives contract volume was derived from our members. This dependence may give them substantial influence over how we operate our business.

Many of our members and clearing firms derive a substantial portion of their income and profit from their trading or clearing activities on or through our exchanges. In addition, trading rights on our exchanges have substantial independent value. The amount of profit that members derive from their trading, brokering and clearing activities and the value of their trading rights

26

are, in part, dependent on the fees they are charged to trade, broker, clear and access our markets, and the rules and structure of our markets. As a result, members may not have the same economic interests as holders of our Class A common stock. In addition, our members may have differing interests among themselves depending on the roles they serve in our markets, their methods of trading and the products they trade. Consequently, members may advocate that we enhance and protect their clearing and trading opportunities and the value of their trading privileges over their investment in our Class A common stock, if any.

Our members have been granted special rights, which protect their trading privileges and require that we maintain open outcry for options products still meeting certain volume thresholds and, in the case of our Class B shareholders, provide them with special board representation.

Under the terms of the organizational documents of our exchanges, our exchange members have certain rights that relate primarily to trading right protections, certain trading fee protections and certain membership benefit protections. Additionally, our Class B shareholders, who are members of our CME exchange, are entitled to elect six directors to our board even if their Class A share ownership interest is very small or non-existent. We have limited ability to eliminate these election rights. In 2018, we held a special meeting of shareholders to eliminate all or some of these director election rights. While the proposal received majority support, it failed to achieve the required support under Delaware law from a majority of the outstanding owners of the Class B common stock. In connection with these rights, our ability to take certain actions that we may deem to be in the best interests of the company and its shareholders, including actions relating to certain pricing decisions, may be limited by the rights of our members.

ITEM 5.    MARKET FOR REGISTRANT’S COMMON EQUITY, RELATED SHAREHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES

Class A Common Stock

Our Class A common stock is currently listed on Nasdaq under the ticker symbol "CME." As of February 10, 2021, there were approximately 6,170 holders of record of our Class A common stock.

Class B Common Stock

Our Class B common stock is not listed on a national securities exchange or traded in an organized over-the-counter market. Each class of our Class B common stock is associated with a membership in a specific division of our CME exchange. CME's rules provide exchange members with trading rights and the ability to use or lease these trading rights. Each share of our Class B common stock can be transferred only in connection with the transfer of the associated trading rights.

27

Class B shares and the associated trading rights are bought and sold or leased through our membership department. Although our Class B shareholders have special voting rights, because our Class B shares have the same equitable interest in our earnings and the same dividend payments as our Class A shares, we expect that the market price of our Class B common stock, if reported separately from the associated trading rights, would be primarily determined by the value of our Class A common stock. As of February 10, 2021, there were approximately 1,565 holders of record of our Class B common stock.

EXECUTIVE SUMMARY

Business Overview

CME Group, a Delaware stock corporation, is the holding company for CME, CBOT, NYMEX, COMEX, NEX and their respective subsidiaries. The holding company structure is designed to provide strategic and operational flexibility. CME Group's Class A common stock is listed on the Nasdaq Global Select Market (Nasdaq) under the ticker symbol "CME."

Our exchange consists of designated contract markets for the trading of futures and options contracts. We also clear futures, options and swaps contracts through our clearing house. Futures contracts, options contracts and swaps contracts provide investors with vehicles for protecting against, and potentially profiting from, price changes in financial instruments and physical commodities.

We are a global company with customer access available virtually all over the world. Our customers consist of professional traders, financial institutions, individual and institutional investors, major corporations, manufacturers, producers, governments and central banks. Customers include both members of the exchange and non-members.

We offer our customers the opportunity to trade futures contracts and options contracts on a range of products including those based on interest rates, equity indexes, foreign exchange, agricultural commodities, energy and metals. Through our cash markets business, we offer fixed income trading through BrokerTec and foreign currency trading through EBS. Our products provide a means for hedging, speculating and allocating assets. We identify new products by monitoring economic trends and their impact on the risk management and speculative needs of our existing and prospective customers.

Most of our products are available for trading through our electronic trading platforms. These execution facilities offer our customers immediate trade execution and price transparency. In addition, trades can be executed through privately negotiated transactions that are cleared and settled through our clearing house.

We also provide optimization services that deliver transaction lifecycle management and information services to help our customers optimize their capital, mitigate their risk and reduce operational costs. Optimization services includes Traiana, TriOptima and Reset.

Our clearing house clears, settles and guarantees futures and options contracts traded through our exchanges, in addition to cleared swaps products. Our clearing house's performance guarantee is an important function of our business. Because of this guarantee, our customers do not need to evaluate the credit of each potential counterparty or limit themselves to a selected set of counterparties. This flexibility increases the potential liquidity available for each trade. Additionally, the substitution of our clearing house as the counterparty to every transaction allows our customers to establish a position with one party and offset the position with another party. This contract offsetting process provides our customers with flexibility in establishing and adjusting positions and provides for collateral and margining efficiencies. Certain BrokerTec and EBS contracts are cleared at third-party clearing houses.

31

Business Trends

Economic Environment. Our customers continue to use our markets as an effective and transparent means to manage risk and meet their investment needs. Trading activity in our centralized markets has fluctuated due to the ongoing uncertainty in the financial markets, fluctuations in the availability of credit, variations in the amount of assets under management as well as the Federal Reserve Bank’s interest rate policy and quantitative easing. We continue to maintain high quality and diverse products as well as various clearing and market data services which support our customers in any economic environment.

Competitive Environment. Our industry is competitive and we continue to encounter competition in all aspects of our business. We expect competition to continue to intensify, especially in light of ongoing regulatory reform in the financial services industry. Competition is influenced by our brand and reputation; the efficiency and security of our settlement, clearing and support services; depth and liquidity of our markets; diversity of product offerings including frequency and quality of new product development and innovative services; our ability to position and expand upon existing products to address changing market needs; efficient and seamless customer experience; transparency, reliability, anonymity and security of transaction processing; the regulatory environment; connectivity, accessibility, flexibility in execution methods and distribution; technology capability and innovation, as well as overall transaction costs. We believe we are very well positioned with respect to these factors. Our asset classes contain products designed to address differing risk management needs, and customers are able to achieve operational and capital efficiencies by accessing our diverse products through our platforms and our clearing house. We face competition from other futures, securities and securities option exchanges; clearing organizations; swap execution facilities; alternative trade execution facilities; technology firms, including market data distributors and electronic trading system developers; and others. As markets continue to evolve, we will continue to adapt our trading technology and clearing services to meet the needs of our customers. The competitive environment to which we are subject is discussed in "Item 1. Business" on page 10.

Regulatory Environment. Exchange-traded derivatives have historically been subject to extensive regulation. Developments in the regulatory environment have the potential to significantly impact our business. Compliance with regulations may require us and our customers to dedicate significant financial and operational resources which could adversely affect our profitability. The regulatory environment to which we are subject is discussed in "Item 1. Business" on page 11.

Business Strategy

Our strategy focuses on maximizing futures and options growth globally, diversifying our business and revenues, and delivering unparalleled customer efficiencies and operational excellence. This strategy allows us to continue to develop into a more broadly diversified financial exchange that provides trading and clearing solutions across a wide range of products and asset classes. Our strategic initiatives are discussed in "Item 1. Business" on page 7.

Revenues

Clearing and transaction fees. A majority of our revenue is derived from clearing and transaction fees, which include electronic trading fees, surcharges for privately negotiated transactions and other volume-related charges for exchange-traded and over-the-counter contracts. Because clearing and transaction fees are assessed on a per-contract or notional value basis, revenues and profitability fluctuate with changes in contract volume. In addition to the business trends noted earlier, our contract volume, and consequently our revenues, tend to increase during periods of economic and geopolitical uncertainty as our customers seek to manage their exposure to, or speculate on, the market volatility resulting from that uncertainty.

While volume has the most significant impact on our clearing and transaction fees revenue, there are four other factors that also influence this source of revenue:

•rate structure;

•product mix;

•venue; and

•the percentage of trades executed by customers who are members compared with non-member customers.

Rate structure. Customers benefit from volume discounts and limits on fees as part of our effort to increase liquidity in certain products. We offer various incentive programs to promote trading and clearing in various products and geographic locations. We may periodically change fees, volume discounts, fee limits and member discounts, perhaps significantly, based on our review of operations and the business environment.

Product mix. We offer exchange-traded futures and options contracts as well as cleared-only interest rate swap contracts. Through our acquisition of NEX, we also offer foreign exchange spot and forward contracts and fixed income products.

32

Rates are varied by product in order to optimize revenue on existing products and to encourage contract volume upon introduction of new products.

Venue. Our exchange and platforms are an international marketplace that brings together buyers and sellers mainly through our electronic trading as well as through open outcry trading and privately negotiated transactions. Any customer who is guaranteed by a clearing firm and who agrees to be bound by our exchange rules is able to obtain direct access to our electronic platforms. Open outcry trading is conducted exclusively by our members, who may execute trades on behalf of customers or for themselves.

Typically, customers submitting trades through our electronic platforms are charged fees for using the platforms in addition to the fees assessed on all transactions executed on our exchange. Customers entering into privately negotiated transactions also incur additional charges beyond the fees assessed on other transactions.

Member/non-member mix. Generally, member customers are charged lower fees than our non-member customers. Holding all other factors constant, revenue decreases if the percentage of trades executed by members increases, and increases if the percentage of non-member trades increases.

Clearing and transaction fees for cash markets business. Our cash markets business provides matching services whereby we match a buyer and seller of financial instruments to allow both parties to complete the trade bilaterally or through a third-party clearing house. We are not involved in the settlement of the contract but charge a transaction fee generally based on volume or notional value of the trade for providing the matching service. The cash markets business also includes BrokerTec Americas, which generates revenue from a matched principal business. This business serves as a fully matched counterparty to offsetting positions entered into by clients on its electronic trading platform to facilitate anonymity and access to clearing and settlement. Revenue is generated from this business generally on a transaction fee basis.

Other sources. Revenue is also derived from other sources including market data and information services and other various services related to our exchange operations.

Market data and information services. We receive market data and information services revenue from the dissemination of our market data to subscribers. Subscribers can obtain access to our market data services either directly or through third-party distributors.

Our service offerings include access to real-time, delayed and end-of-day quotations, trade and summary market data for our products and other data sources. Users of our basic service receive real-time quotes and pay a flat monthly fee for each screen, or device, displaying our market data. Alternatively, customers can subscribe to market data provided on a limited group of products. The fee for this service is also a flat rate per month.

Pricing for our market data services is based on the value of the service provided and the price of comparable services offered by our competitors. Increases or decreases in our market data and information services revenue are influenced by changes in our price structure and incentive programs for existing market data offerings, introduction of new market data services and changes in the number of devices in use. General economic factors that affect the financial services industry, which constitutes our primary customer base, also influence revenue from our market data services.

Other revenues. Other revenue includes access and communication fees. Access and communication fees are connectivity fees charged to members and clearing firms that utilize our various telecommunications networks and communications services. Our communication services include our co-location program as well as the connectivity charges to customers of the CME Globex platform. Access fee revenue varies depending on the type of connection provided to customers.

Other revenues include revenues from our optimization services, which include fees for risk management and information services for the over-the-counter markets, including portfolio reconciliation and post-trade processing. Revenue earned from these services is typically generated through subscriptions or transaction fees.

Other revenues also include fees for post-trade services, fees for collateral management, equity subscription fees and fees for trade order routing through agreements from various strategic relationships as well as other services to members and clearing firms.

Expenses

The majority of our expenses do not vary directly with changes in our contract volume. However, licensing and other fee agreements can vary directly with certain equity, energy and swap volumes as well as the majority of our employee bonuses vary directly with overall contract volume.

Compensation and benefits. Compensation and benefits expense is our most significant expense and includes employee wages, bonuses, stock-based compensation, benefits and employer taxes. Changes in this expense are driven by fluctuations in the number of employees, increases in wages as a result of inflation or labor market conditions, changes in rates for employer taxes and other cost increases affecting benefit plans. In addition, this expense is affected by the composition of our workforce.

33

The expense associated with our bonus and stock-based compensation plans can also have a significant impact on this expense category.

The bonus component of our compensation and benefits expense is based on our financial performance. Under the performance criteria of our annual incentive plans, the bonus funded under the plans is based on achieving certain financial performance targets established by the compensation committee of our board of directors. The compensation committee has discretion to make equitable adjustments to the cash earnings performance calculation to reflect effects of unplanned operating results or capital expenditures to meet intermediate- to long-term growth opportunities.

In general, stock-based compensation is a non-cash expense related to restricted stock and performance share grants. Stock-based compensation varies depending on the quantity and fair value of awards granted. The fair value of restricted stock awards and other performance share grants is based on either the share price on the date of the grant or a model of expected future stock prices.

Professional fees and outside services. This expense includes fees for consulting services received on strategic and technology initiatives; regulatory and other compliance matters; temporary labor as well as legal and accounting fees. This expense may fluctuate as a result of changes in services required to complete initiatives, handle legal proceedings and comply with regulatory and compliance requirements.

Depreciation and amortization. Depreciation and amortization expense results from the depreciation of long-lived assets such as buildings, leasehold improvements, furniture, fixtures and equipment. This expense also includes the amortization of purchased and internally developed software.

Amortization of purchased intangibles. Amortization of purchased intangibles includes amortization of intangible assets obtained in our acquisitions of CBOT Holdings, Inc., NYMEX Holdings, Inc. and NEX as well as other asset and business acquisitions. Intangible assets subject to amortization consist primarily of clearing firm, market data and other customer relationships.

Other expenses. We incur additional ongoing expenses for communications, technology support services and various other activities necessary to support our operations.

•Technology expense consists of costs related to maintenance of the hardware and software required to support our technology. It also includes costs for network connections for our electronic platforms and some market data customers; telecommunications costs of our exchange, and fees paid for access to external market data. This expense may be driven by system capacity, functionality and redundancy requirements. It also may be impacted by growth in electronic contract volume and changes in the number of telecommunications hubs and connections which allow customers outside the U.S. to access our electronic platforms directly.

•Licensing and other fee agreements expense includes license fees paid as a result of contract volume in equity index products. This expense also includes royalty fees and broker rebates on energy and metals products as well as revenue sharing on cleared swaps contracts and some new product launches. This expense fluctuates with changes in contract volumes as well as changes in fee structures.

•Other expenses include occupancy and building operations expenses including rent, maintenance, real estate taxes, utilities and other related costs related to leased property in Chicago, New York, the U.K., India as well as other smaller locations throughout the world. Other expenses also include marketing and travel-related expenses as well as general and administrative costs. Marketing, advertising and public relations expense includes media, print and other advertising costs, as well as costs associated with our product promotion. Other expenses also include litigation and customer settlements, impairment charges on operating assets, gains and losses on disposals of certain operating assets, and foreign currency transaction gains and losses resulting from changes in exchange rates on certain foreign monetary assets and liabilities.

Non-Operating Income and Expenses

Income and expenses incurred through activities outside of our core operations are considered non-operating. These activities include non-core investing and financing activities.

•Investment income includes income from short-term investment of clearing firms' cash performance bonds and guaranty fund contributions as well as excess operating cash; interest income and realized gains and losses from our marketable securities; realized gains and losses as well as dividend income from our strategic equity investments, and gains and losses on trading securities in our non-qualified deferred compensation plans. Investment income is influenced by market interest rates, changes in the levels of cash performance bonds deposited by clearing firms, the amount of dividends distributed by our strategic investments and the availability of funds generated by operations.

34

•Interest and other borrowing costs expense includes charges associated with various short-term and long-term funding facilities, including commitment fees on lines of credit agreements.

•Equity in net earnings (losses) of unconsolidated subsidiaries includes income and losses from our investments in S&P/Dow Jones Indices LLC (S&P/DJI), Shanghai CFETS-NEX International Money Broking Co., Ltd. and Dubai Mercantile Exchange.

•Other income (expense) includes expenses related to the distribution of a portion of interest earned on performance bond collateral reinvestment to the clearing firms, gains and losses on derivative contracts as well as other various income and expenses outside our core operations.

CRITICAL ACCOUNTING POLICIES

The notes to our consolidated financial statements include disclosure of our significant accounting policies. In establishing these policies within the framework of accounting principles generally accepted in the U.S., management must make certain assessments, estimates and choices that will result in the application of these principles in a manner that appropriately reflects our financial condition and results of operations. Critical accounting policies are those policies that we believe present the most complex or subjective measurements and have the most potential to affect our financial position and operating results. While all decisions regarding accounting policies are important, there are certain accounting policies that we consider to be critical. These critical policies, which are presented in detail in the notes to our consolidated financial statements, relate to the valuation of financial instruments, goodwill and intangible assets, revenue recognition, income taxes and internal use software costs.

Valuation of financial instruments. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date, or an exit price. We have categorized financial instruments measured at fair value into the following three-level fair value hierarchy based upon the level of judgment associated with the inputs used to measure the fair value:

•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.

For further discussion regarding the fair value of financial assets and liabilities, see note 2 of the notes to the consolidated financial statements.

Goodwill and intangible assets. We review goodwill for impairment on a quarterly basis and whenever events or circumstances indicate that its carrying value may not be recoverable. Goodwill may be tested quantitatively for impairment by comparing the carrying value of a reporting unit to its estimated fair value. Estimating the fair value of a reporting unit involves the use of valuation techniques that rely on significant estimates and assumptions. These estimates and assumptions may include forecasted revenue growth rates; forecasted operating margins; risk-adjusted discount rates; forecasted economic and market conditions, and industry multiples. We base our fair value estimates on assumptions we believe to be reasonable given the information that is available to us at the time of our assessment; however, actual future results may differ significantly from those estimates. Under certain favorable circumstances, goodwill may be reviewed qualitatively for indications of impairment without utilizing valuation techniques to estimate fair value. The qualitative assessment of goodwill may rely on significant assumptions about forecasts of revenue growth, operating margins and economic conditions as well as overall market and industry-specific trends. In addition, the carrying value of goodwill, as denominated in foreign currencies, is adjusted each reporting period as a result of movements in foreign currency exchange rates relative to the U.S. dollar. Such foreign currency translation adjustments are recorded in accumulated other comprehensive income (loss) within shareholders' equity.

We also review indefinite-lived intangible assets on a quarterly basis or more frequently when events and circumstances indicate that their carrying values may not be recoverable. Indefinite-lived intangible assets may be tested quantitatively for impairment by comparing their carrying values to their estimated fair values. Estimating the fair value of indefinite-lived intangible assets involves the use of valuation techniques that rely on significant estimates and assumptions. These estimates and assumptions may include forecasted revenue growth rates, forecasted allocations of expense and risk-adjusted discount rates. We base our fair value estimates on assumptions we believe to be reasonable given the information that is available to us at the time of our assessment; however, actual future results may differ significantly from those estimates. Similar to goodwill, under certain favorable circumstances, indefinite-lived intangible assets may be reviewed qualitatively for indications of impairment without utilizing valuation techniques to estimate fair value. The qualitative assessment of indefinite-lived intangible assets may rely on significant assumptions about forecasts of revenue growth, operating margins and economic conditions as well as overall market and industry-specific trends.

35

Intangible assets subject to amortization are also assessed for impairment on a quarterly basis or more frequently when indicated by a change in economic or operational circumstances. The impairment assessment of these assets requires management to first compare the carrying value of the amortizing asset to its undiscounted net cash flows. If the carrying value exceeds the undiscounted net cash flows, management is then required to estimate the fair value of the assets and record an impairment loss for the excess of the carrying value over the fair value. In connection with this impairment assessment, management also challenges the useful lives of our definite-lived intangible assets on a periodic basis.

Revenue recognition. A significant portion of our revenue is derived from the clearing and transaction fees we assess on each contract executed through our trading venues and cleared through our clearing house. Clearing and transaction fees are recognized as revenue when a buy and sell order are matched and when the trade is cleared. On occasion, the customer's exchange trading privileges may not be properly entered by the clearing firm and incorrect fees are charged for the transactions in the affected accounts. When this information is corrected within the time period allowed by the exchange, a fee adjustment is provided to the clearing firm. A reserve is established for estimated fee adjustments to reflect corrections to customer exchange trading privileges. This reserve has historically been immaterial. The reserve is based on the historical pattern of adjustments processed as well as management's estimate of future adjustment activity.

Income taxes. Calculation of the income tax provision includes an estimate of the income taxes that will be paid for the current year as well as an estimate of income tax liabilities or benefits deferred into future years. Deferred tax assets are reviewed to determine if they will be realized in future periods. To the extent it is determined that some deferred tax assets may not be fully realized, the assets are reduced to their realizable value by a valuation allowance. The calculation of our tax provision involves uncertainty in the application of complex tax regulations and we occasionally may consult with relevant tax authorities or engage third party expertise where appropriate. We recognize potential liabilities for anticipated tax audit issues in the United States and other applicable foreign tax jurisdictions using a more-likely-than-not recognition threshold based on the technical merits of the tax position taken or expected to be taken. If the actual obligation of these amounts varies from our estimate, our income tax provision would be reduced or increased at the time that determination is made. This determination may not be known for several years. Past tax audits have not resulted in tax adjustments that resulted in a material change to the income tax provision in the year the audit was completed. The effective tax rate, defined as the income tax provision as a percentage of income before income taxes, will vary from year to year based on changes in tax jurisdictions, tax rates and regulations. In addition, the effective tax rate will vary with changes to income that are not subject to income tax and changes in expenses or losses that are not deductible, such as the utilization of foreign net operating losses.

Internal use software costs. Certain internal and external costs that are incurred in connection with developing or obtaining software for internal use are capitalized. We also enter into software hosting arrangements for software projects maintained in the cloud. Software development costs incurred during the planning or maintenance stages of a software project are expensed as incurred, while costs incurred during the application development stage are capitalized and are amortized over the estimated useful life of the software, which is generally two to four years, but up to eight years for certain trading and clearing applications, depending upon expected useful lives. Amortization of capitalized costs begins only when the software becomes ready for its intended use. In addition, software assets are assessed for impairment when events or circumstances indicate that the carrying values may not be recoverable or that a reduction in the estimated useful lives is warranted.

Clearing and Transaction Fees

Futures and Options

The following table summarizes our total contract volume, revenue and average rate per contract for futures and options. Total contract volume includes contracts that are traded on our exchange and cleared through our clearing house and certain 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. Contract volume and average rate per contract disclosures below exclude trading volume for the cash markets business as well as interest rate swaps.

					Year-over-Year Change
	2020		2019		2020-2019
Total contract volume (in millions)	4,820.6		4,830.0		—	%
Clearing and transaction fees (in millions)	$	3,384.6	$	3,396.3	—
Average rate per contract	0.702		0.703		—

We estimate the following decreases in clearing and transaction fees based on a change in total contract volume and a change in average rate per contract during 2020 compared with 2019.

	Year-over-Year Change
(in millions)	2020-2019
Decrease due to change in total contract volume	$	(6.6)
Decrease due to change in average rate per contract	(5.1)
Net decrease in clearing and transaction fees	$	(11.7)

37

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 changes in each is only an approximation.

Contract Volume

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

					Year-over-Year Change
(amounts in thousands)	2020		2019		2020-2019
Average Daily Volume by Product Line:

Electronic Volume as a Percentage of Total Volume	94	%	90	%

In 2020 when compared with 2019, overall market volatility declined following a period of very high volatility in the first quarter of 2020. During the first quarter of 2020, the Federal Reserve made the unexpected decision to lower the federal funds rate due to economic concerns from the COVID-19 pandemic, which resulted in significant volatility within the financial and equity markets. However, interest rate volatility subsided following indication by the Federal Reserve that it did not intend to raise interest rates in the foreseeable future. Equity market volatility remained high throughout 2020 as a result of the governmental and business response to the COVID-19 pandemic, as well as political uncertainty surrounding the U.S. Presidential and Congressional elections in November. In addition, heightened producer price competition within the oil markets combined with lower energy demands during the COVID-19 pandemic resulted in significant market volatility within the energy market during the first quarter of 2020. However, this volatility subsided as oil prices stabilized and demand for crude oil remained low for the remainder of 2020. We believe these factors led to the changes in volume in 2020 when compared with 2019.

Interest Rate Products

The following table summarizes average daily contract volume for our key interest rate products. Eurodollar front 8 contracts include contracts expiring within two years. Eurodollar back 32 contracts include contracts expiring within three to ten years. 

			Year-over-Year Change
(amounts in thousands)	2020	2019	2020-2019
Eurodollar futures and options:
Front 8 futures	1,311	1,997	(34)	%
Back 32 futures	633	661	(4)
Options	1,058	1,685	(37)
U.S. Treasury futures and options:
10-Year	2,026	2,324	(13)
5-Year	1,081	1,358	(20)
2-Year	517	749	(31)
Treasury bond	484	467	3
Federal Funds futures and options	207	356	(42)

In 2020 when compared with 2019, overall interest rate contract volume decreased. We believe this was due to the Federal Reserve's decision to cut interest rates to near zero in early 2020 and its indication that it would not raise interest rates in the foreseeable future in response to the economic impact of the COVID-19 pandemic.

Equity Index Products

The following table summarizes average daily contract volume for our key equity index products. Volume below for the year ended 2019 includes Micro-E-mini contract volumes for each index beginning on May 6, 2019, which was the date the contracts were launched.

			Year-over-Year Change
(amounts in thousands)	2020	2019	2020-2019
E-mini S&P 500 futures and options	3,555	2,338	52	%
E-mini Nasdaq 100 futures and options	1,302	592	120
E-mini Russell 2000 futures and options	302	168	79

In 2020 when compared with 2019, equity index contract volume increased due to higher overall volatility in the equity market in 2020, particularly in the first and fourth quarters. We believe the increase in volatility was attributable to uncertainty surrounding the economic impact of governmental and business actions to combat the COVID-19 pandemic, as well as political uncertainty surrounding the U.S. presidential and congressional elections. Average daily contract volume in 2020 also included Micro-E-mini equity index contract volume of approximately 1.8 million per day compared to approximately 0.3 million per day in 2019. Micro-E-mini equity index contracts have a notional size of one-tenth of the traditional E-mini contracts.

Foreign Exchange Products

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

			Year-over-Year Change
(amounts in thousands)	2020	2019	2020-2019
Euro	237	232	2	%
Japanese yen	123	139	(12)
British pound	116	129	(10)
Australian dollar	107	105	2

In 2020 when compared with 2019, overall foreign exchange contract volume was flat, which we believe resulted from lower overall volatility. In 2020, market volatility subsided in the second half of the year following very high foreign exchange volatility in the first quarter caused by significant uncertainty surrounding the economic impacts of governmental and business

39

actions to combat the COVID-19 pandemic. In addition, we believe foreign exchange trading declined slightly due to operational strains from stay at home orders and risk aversion by market participants during the COVID-19 pandemic.

Agricultural Commodity Products

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

			Year-over-Year Change
(amounts in thousands)	2020	2019	2020-2019
Corn	444	525	(15)	%
Soybean	307	263	16
Wheat	220	215	2

Overall commodity contract volume was relatively flat in 2020 when compared with 2019. Corn contract volume decreased due to lower price volatility, which we believe was caused by large stock piles and lower demand. We believe the increase in soybean contract volume was due to an increase in demand for commodities from China.

Energy Products

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

			Year-over-Year Change
(amounts in thousands)	2020	2019	2020-2019
WTI crude oil	1,255	1,329	(6)	%
Natural gas	639	529	21
Refined products	366	381	(4)

Overall energy contract volume was relatively flat in 2020 when compared with 2019, which we believe was due to periods of high volatility in early 2020 followed by periods of low volatility as a result of governmental and business actions to combat the COVID-19 pandemic. The increase in natural gas volume is the result of significant price declines in early 2020 followed by price increases in the second half of 2020 as a result of higher demand during the winter months. This was partially offset by a decrease in crude oil volume due to a reduction in demand caused by the COVID-19 pandemic.

Metal Products

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

			Year-over-Year Change
(amounts in thousands)	2020	2019	2020-2019
Gold	456	433	5	%
Silver	123	107	15
Copper	98	98	—

Overall metal contract volume increased in 2020 when compared with 2019 due to an increase in metals price volatility caused by investors using gold and other precious metals as safe-haven alternative investments due to significant uncertainty within other markets caused by the COVID-19 pandemic.

Average Rate per Contract

The average rate per contract was substantially the same in 2020 when compared with 2019. There was an increase in the average rate per contract due to a change in product mix. Interest rate contract volume decreased by 12 percentage points as a percent of total volume, while all other products collectively increased by 12 percentage points. In general, interest rate products have a lower rate per contract compared with the remaining contracts. The increase in the average rate per contract was offset by the introduction of the micro-E-mini equity index contracts in mid-2019, which have a lower average rate per contract compared with a standard E-mini contract. Micro-E-mini equity index contracts have a notional size of one-tenth of the traditional E-mini contracts.

40

Cash Markets Business

Total clearing and transaction fees revenue in 2020 includes $447.4 million of transaction fees attributable to the cash markets business acquired from NEX compared with $483.0 million in 2019. This revenue primarily includes BrokerTecs's fixed income volume and EBS foreign exchange volume.

					Year-over-Year Change
(amounts in millions)	2020		2019		2020-2019
BrokerTec fixed income transaction fees	$	173.2	$	191.5	(10)	%
EBS foreign exchange transaction fees	179.3		191.8		(7)	%

The related average daily notional value for the years ended 2020 and 2019 for key cash markets products were as follows:

					Year-over-Year Change
(amounts in billions)	2020		2019		2020-2019
U.S. Treasury	$	125.9	$	164.8	(24)	%
European Repo (in euros)	264.4		269.6		(2)	%
Spot FX	71.5		75.1		(5)	%

Overall average daily notional value for the cash markets business decreased in 2020 when compared with 2019 due to expectations of potentially low interest rates for an extended period of time and economic uncertainty surrounding the COVID-19 pandemic.

Concentration of Revenue

We bill a significant portion of our clearing and transaction fees 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 clearing firm represented approximately 10% of our clearing and transaction fees in 2020. 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 an ongoing loss of revenue received from or through a particular clearing firm.

Other Sources of Revenue

Market data and information services. In 2020 when compared with 2019, the increase in market data and information services revenue was largely attributable to an increase in certain device fees, an increase in subscriber device counts and higher demand for CME Group data.

The two largest resellers of our market data represented, in aggregate, approximately 35% of our market data and information services revenue in 2020. 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.

Other revenues. The increase in other revenues in 2020 when compared with 2019 is largely attributable to an increase in custody fees due to a new rate structure put in place in 2020.

2020 Compared With 2019

Operating expenses decreased by $34.0 million in 2020 when compared with 2019. The following table shows the estimated impact of key factors resulting in the net decrease in operating expenses.

(dollars in millions)	Year- over-Year Change		Change as a Percentage of 2019 Expenses
Bonus expense	$	(54.3)	(2)	%
Intangible and fixed asset impairments	(49.8)		(2)
Travel and entertainment	(25.0)		(1)
Marketing	(20.9)		(1)
Stock-based compensation	11.1		—
Professional fees and outside services	17.2		1
Licensing and other fee agreements	72.7		3
Other expenses, net	15.0		1
Total	$	(34.0)	(1)	%

Overall operating expenses decreased in 2020 when compared with 2019 due to the following reasons:

•Bonus expenses decreased in 2020 largely due to a reduction in headcount with legacy NEX businesses in conjunction with our planned integration, as well as performance relative to our 2020 cash earnings target when compared with 2019 performance relative to our 2019 cash earnings target.

•During 2019, we recognized higher impairment charges on certain intangibles and fixed assets due to the disposal of various businesses.

•Travel and entertainment expenses decreased as a result of the company's response to the COVID-19 pandemic, with the vast majority of staff working remotely during 2020.

•Marketing expenses decreased compared with 2019 due to a reduction in planned advertising, media campaigns and special promotional events.

Increases in operating expenses in 2020 when compared with 2019 were as follows:

•Licensing and other fee agreements expenses increased during 2020 due to higher fees related to revenue sharing agreements for certain equity contracts, which resulted from an increase in volume and an increase in license rates for certain products.

•Professional fees and outside services expenses increased due to higher legal fees compared to 2019, as well as professional and legal fees incurred in 2020 in connection with to our recently announced joint venture with IHS Markit.

•Stock-based compensation expense increased due to acceleration of certain grants and the impact related to our September 2019 and 2020 grants.

Non-Operating Income (Expense)

					Year-over-Year Change
(dollars in millions)	2020		2019		2020-2019
Investment income	$	182.7	$	637.9	(71)	%
Interest and other borrowing costs	(166.2)		(178.0)		(7)
Equity in net earnings (losses) of unconsolidated subsidiaries	190.6		176.8		8
Other income (expense)	(122.4)		(534.9)		(77)
Total Non-Operating	$	84.7	$	101.8	(17)

Investment income. The decrease in investment income in 2020 when compared with 2019 was largely due to a decline in earnings from cash performance bond and guaranty fund contributions that are reinvested. The decrease in earnings resulted primarily from lower rates of interest earned in the cash account at the Federal Reserve Bank of Chicago following significant interest rate cuts in early 2020 despite an increase in our average reinvestment amount.

Interest and other borrowing costs. Interest and other borrowing costs were lower in 2020 when compared with 2019, primarily due to lower borrowing costs on commercial paper issuances, as there were higher average balances of commercial paper outstanding during 2019 when compared with 2020. Interest and other borrowing costs were also lower during 2020 due to interest expense recognized on the €350.0 million fixed rate notes and the ¥19.1 billion term loan assumed as part of the NEX acquisition in 2018 and subsequently paid off during the first quarter of 2019.

Equity in net earnings (losses) of unconsolidated subsidiaries. Higher income generated from our S&P/DJI business venture contributed to an increase in equity in net earnings (losses) of unconsolidated subsidiaries in 2020 when compared with 2019.

Other income (expense). In 2020 when compared with 2019, we recognized lower expense related to a reduction in the distribution of interest earned on performance bond collateral reinvestments to the clearing firms due to lower interest income earned on our reinvestment. In addition, a gain of $1.5 million was recognized on derivative contracts in 2020 compared with a net loss of $17.7 million in 2019.

Income Tax Provision

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

	2020		2019		Year-over-Year Change
					2020-2019
Year ended December 31	22.6	%	21.3	%	1.3	%

In 2020 when compared with 2019, the effective tax rate was higher due to the recognition of additional benefits from the Internal Revenue Code Section 250 deduction in 2019. Proposed FDII Deduction regulations were released in 2019 and as a result, we revised our income tax calculations to reflect the proposed guidance. The benefit recognized in 2019 includes estimates for the deduction for 2018 and 2019, whereas the benefit recognized in 2020 only includes the deduction for 2020.

LIQUIDITY AND CAPITAL RESOURCES

Cash Requirements

We have historically met our funding requirements with cash generated by our ongoing operations. However, as part of the funding for the NEX acquisition, we utilized our commercial paper program in late 2018 and through the beginning of the second quarter of 2020 for short-term funding requirements. While our cost structure is generally fixed in the short term, our sources of operating cash are largely dependent on contract trading volume levels. In addition to using our existing cash, cash equivalents, marketable securities and cash generated from operations, we may continue to utilize our commercial paper program to meet our working capital needs, capital expenditures and other commitments. It is also possible that we may need to raise additional funds to finance our activities through future public debt offerings or by direct borrowings from financial institutions through our committed revolving credit facilities.

Future capital expenditures for technology are anticipated as we continue to support our growth through increased system capacity, performance improvements, integration of acquired platforms as well as improvements to some of our office spaces. Each year, capital expenditures are incurred for improvements to and modification of our offices, remote data centers, telecommunications network and other operating equipment. In 2021, we expect capital expenditures to total approximately $180.0 million to $190.0 million, net of any leasehold improvement allowances and any one-time costs associated with the NEX integration. We continue to monitor our capital needs and may revise our forecasted expenditures as necessary in the future.

We intend to continue to pay a regular quarterly dividend to our shareholders, with a target of between 50% to 60% of the prior year's cash earnings. The decision to pay a dividend and the amount of the dividend, however, remains within the discretion of our board of directors and may be affected by various factors, including our earnings, financial condition, capital requirements, levels of indebtedness and other considerations our board of directors deems relevant. We are also required to comply with restrictions contained in the general corporation laws of our state of incorporation, which could also limit our ability to declare and pay dividends. On February 3, 2021 the board of directors declared a regular quarterly dividend of $0.90 per share. The dividend will be payable on March 25, 2021 to shareholders of record on March 10, 2021. Assuming no changes in the number of shares outstanding, the first quarter dividend payment will total approximately $322.0 million. The board of directors also declared an additional, annual variable dividend of $2.50 per share on December 10, 2020 paid on January 13, 2021 to the shareholders of record on December 28, 2020. In general, the amount of the annual variable dividend will be determined by the end of each year, and the level will increase or decrease from year to year based on operating results, capital expenditures, potential merger and acquisition activity and other forms of capital return including regular dividends and share buybacks during the prior year.

Sources and Uses of Cash

The following is a summary of cash flows from operating, investing and financing activities.

					Year-over-Year Change
(dollars in millions)	2020		2019		2020-2019
Net cash provided by operating activities	$	2,715.6	$	2,672.8	2	%
Net cash used in investing activities	(175.5)		(152.6)		15
Net cash used in financing activities	(2,458.2)		(2,340.8)		5

Operating activities

Net cash provided by operating activities was relatively flat in 2020 compared with 2019.

Investing activities

The increase in cash used in investing activities in 2020 compared with 2019 was largely due to a decrease in cash proceeds received on sales of certain privately-held investments.

Financing activities

Cash used in financing activities was higher in 2020 when compared with 2019 due to an increase in the amount of cash dividends paid. The increase in cash used in financing activities was partially offset by a reduction in the amount of outstanding debt repayments in 2020 compared with 2019.

Debt Instruments

The following table summarizes our debt outstanding as of December 31, 2020:

(in millions)	Par Value
Fixed rate notes due September 2022, stated rate of 3.00% (1)	$	750.0
Fixed rate notes due May 2023, stated rate of 4.30%	€	15.0
Fixed rate notes due March 2025, stated rate of 3.00% (2)	$	750.0
Fixed rate notes due June 2028, stated rate of 3.75%	$	500.0
Fixed rate notes due September 2043, stated rate of 5.30% (3)	$	750.0
Fixed rate notes due June 2048, stated rate of 4.15%	$	700.0

 _______________

(1)We maintained 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%.

(2)We maintained 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 3.11%.

(3)We maintained 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 $2.4 billion multi-currency revolving senior credit facility with various financial institutions, which matures in November 2022. The proceeds from this facility can be used for general corporate purposes, which includes providing liquidity for our clearing house in certain circumstances at our discretion and, if necessary, for maturities of commercial paper. As long

44

as we are not in default under this facility, we have the option to increase it up to $3.0 billion with the consent of the agent and lenders providing the additional funds. This facility is voluntarily pre-payable from time to time without premium or penalty. Under this facility, we are required to remain in compliance with a consolidated net worth test, which is defined as our consolidated shareholders' equity at September 30, 2017, 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 this facility, but the outstanding commercial paper balance is backstopped against this facility.

We maintain a 364-day multi-currency revolving secured credit facility with a consortium of domestic and international banks to be used in certain situations by CME Clearing. The facility provides for borrowings of up to $7.0 billion. We may use the proceeds to provide temporary liquidity in the unlikely event a clearing firm fails to promptly discharge an obligation to CME Clearing, in the event of a liquidity constraint or default by a depository (custodian for our collateral), 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, or in other cases as provided by the CME rulebook. Clearing firm guaranty fund contributions received in the form of cash or U.S. Treasury securities as well as the performance bond assets (pursuant to the CME rulebook) can be used to collateralize the facility. At December 31, 2020, guaranty fund contributions available to collateralize the facility totaled $8.0 billion. We have the option to request an increase in the line from $7.0 billion to $10.0 billion. Our 364-day facility contains a requirement that CME remains 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. We currently do not have any borrowings outstanding under this facility.

The indentures governing our fixed rate notes, our $2.4 billion multi-currency revolving senior credit facility and our 364-day multi-currency revolving secured credit facility 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 December 31, 2020, we have excess borrowing capacity for general corporate purposes of approximately $2.4 billion under our multi-currency revolving senior credit facility.

At December 31, 2020, we were in compliance with the various covenant requirements of all our debt facilities.

CME Group, as a holding company, has no operations of its own. Instead, it relies on dividends declared and paid to it by its subsidiaries in order to provide a portion of the funds which it uses to pay dividends to its shareholders.

To satisfy our performance bond obligation with Singapore Exchange Limited, we may pledge CME-owned U.S. Treasury securities or U.S. dollars in lieu of, or in combination with, irrevocable letters of credit. At December 31, 2020, we had pledged letters of credit totaling $310.0 million.

The following table summarizes our credit ratings as of December 31, 2020:

Rating Agency	Short-Term Debt Rating	Long-Term 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 $1.6 billion at December 31, 2020 and December 31, 2019. The balance retained in cash and cash equivalents is a function of anticipated or possible short-term cash needs, prevailing interest rates, our corporate 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, U.S. government agency securities and U.S. Treasury security reverse repurchase agreements, and short-term bank deposits. 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 on the consolidated balance sheets.

Our practice is to have our pension plan 100% funded at each year end on a projected benefit obligation basis, while also satisfying any minimum required contribution and obtaining the maximum tax deduction. Based on our actuarial projections, we estimate that an additional contribution may be necessary in 2021 to meet our funding goal. However, the amount of the

45

actual contribution is contingent on various factors, including the actual rate of return on our plan assets during 2021 and the December 31, 2021 discount rate.

Regulatory Requirements

CME is regulated by the 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 was designated by the Financial Stability Oversight Council as a systemically important financial market utility under Title VIII of Dodd-Frank. As a result, CME must comply with CFTC regulations applicable to a systemically important DCO for financial resources and liquidity resources. CME is in compliance with all DCO financial requirements.

CME, CBOT, NYMEX and COMEX are regulated by the CFTC as Designated Contract Markets (DCM). DCMs 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. Our DCMs are in compliance with all DCM financial requirements.

BrokerTec Americas LLC is required to maintain sufficient net capital under Securities Exchange Act of 1934, as amended (Exchange Act), Rule 15c3-1 (the Net Capital Rule). The Net Capital Rule focuses on liquidity and is designed to protect securities customers, counterparties, and creditors by requiring that broker-dealers have sufficient liquid resources on hand at all times to satisfy claims promptly. Rule 15c3-3, or the customer protection rule, which complements Rule 15c3-1, is designed to ensure that customer property (securities and funds) in the custody of broker-dealers is adequately safeguarded. By law, both of these rules apply to the activities of registered broker-dealers, but not to unregistered affiliates. The firm began operating as a (k)(2)(i) broker-dealer in November 2017 following notification to FINRA and the SEC. A company operating under the (k)(2)(i) exemption is not required to lock up customer funds as would otherwise be required under Rule 15c3-3 of the Exchange Act.

ITEM 7A.    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are subject to various market risks, including those caused by changes in interest rates, credit and foreign currency exchange rates.

Interest Rate Risk

Debt outstanding at December 31, 2020 consisted of fixed-rate borrowings of $3.4 billion (in U.S. dollar equivalent). Changes in interest rates impact the fair values of fixed-rate debt, but do not impact earnings or cash flows. We did not have any variable-rate borrowings at December 31, 2020.

Credit Risk

CME Clearing House

Our clearing house acts as the counterparty to all trades consummated on our exchanges as well as through third-party exchanges and swaps markets for which we provide clearing services. As a result, we are exposed to significant credit risk of third parties, including clearing firms. We are also exposed, indirectly, to the credit risk of customers of our clearing firms. These parties may default on their obligations due to bankruptcy, lack of liquidity, operational failure or other reasons.

In order to ensure performance, we establish and monitor financial requirements for our clearing firms. We set minimum performance bond requirements for exchange-traded and interest rate swaps products. For clearing firms, we establish performance bond requirements to cover at least 99% of expected price changes for a given product within a given historical period with further quantitative and qualitative considerations based on market risk. We establish haircuts applied to collateral deposited to meet performance bond requirements to cover at least 99% of expected price changes and foreign currency changes for a given asset within a given historical period with further quantitative and qualitative considerations. Haircuts vary depending on the type of collateral and maturity. We mark-to-market open positions of clearing firms at least once a day (twice a day for futures and options contracts) and require payment from clearing firms whose positions have lost value and make payments to clearing firms whose positions have gained value. We have the capability to mark-to-market more frequently as market conditions warrant. These practices allow our clearing house to quickly identify any clearing firms that may not be able to satisfy the financial obligations resulting from changes in the prices of their open positions before those financial obligations become exceptionally large and jeopardize the ability of our clearing house to ensure performance of their open positions.

Although we have policies and procedures to help ensure that our clearing firms can satisfy their obligations, these policies and procedures may not succeed in detecting problems or preventing defaults. We also have in place various measures intended to enable us to cover any default and maintain liquidity.

Despite our safeguards, we cannot guarantee that these measures will be sufficient to protect us from a default or that we will not be materially and adversely affected in the event of a significant default.

46

We maintain two separate financial safeguard packages:

•a financial safeguard package for all futures, options and over-the-counter swap contracts other than cleared interest rate swap contracts (base package); and

•a financial safeguard package for cleared interest rate swap contracts.

In the unlikely event of a payment default by a clearing firm, we would first apply assets of the defaulting clearing firm to satisfy its payment obligation. These assets include the defaulting firm's guaranty fund contributions, performance bonds and any other available assets, such as assets required for clearing membership and any associated trading rights. In addition, we would make a demand for payment pursuant to any applicable guarantee provided to us by the parent company of the clearing firm. Thereafter, if the payment default remains unsatisfied, we would use our corporate contributions designated for the respective financial safeguard package. We would then use guaranty fund contributions of other clearing firms within the respective financial safeguard package and funds collected through an assessment against solvent clearing firms within the respective financial safeguard package to satisfy the deficit.

We maintain a $7.0 billion 364-day multi-currency line of credit with a consortium of domestic and international banks to be used in certain situations by our clearing house. We have the option to request an increase in the line from $7.0 billion to $10.0 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 of the collateral) or in the event of a temporary disruption with the payments systems that would delay payment of settlement variation between us and our clearing firms. The credit agreement requires us to pledge certain assets to the line of credit custodian prior to drawing on the line of credit. Pledged assets may include clearing firm guaranty fund deposits held by us in the form of cash or U.S. Treasury securities. Performance bond collateral of a defaulting clearing firm may also be used to secure a draw on the line. In addition to the 364-day multi-currency line of credit, we also have the option to use our $2.4 billion multi-currency revolving senior credit facility to provide liquidity for our clearing house in the unlikely event of default.

At December 31, 2020, aggregate performance bond deposits for clearing firms for both financial safeguard packages was $211.9 billion including cash performance bond deposits, non-cash deposits, Interest Earnings Facility funds and letters of credit. A defaulting firm's performance bond deposits can be used in the event of default of that clearing firm.

The following shows the available assets at December 31, 2020 in the event of a payment default by a clearing firm for the base financial safeguard package after first utilizing the defaulting firm's available assets:

(in millions)	Clearing House Available Assets
Designated corporate contributions for futures and options(1)	$	100.0
Guaranty fund contributions(2)	4,654.1
Assessment powers(3)	12,798.9

_______________

(1)Our clearing house designates $100.0 million of corporate contributions to satisfy a clearing firm default in the event that the defaulting clearing firm's guaranty contributions and performance bonds do not satisfy the deficit.

(2)Guaranty fund contributions of clearing firms include guaranty fund contributions required of clearing firms, but do not include any excess deposits held by us at the direction of clearing firms.

(3)In the event of a clearing firm default, if a loss continues to exist after the utilization of the assets of the defaulted firm, our corporate contribution and the non-defaulting clearing firms' guaranty fund contributions, we would assess all non-defaulting clearing members as provided in the rules governing the guaranty fund. We could assess non-defaulting clearing members 275% of their existing guaranty fund requirements up to a maximum of 550% of their existing guaranty fund requirements as provided in the rules. Assessment powers are calculated to reflect the potential obligation that each clearing member could be called for in the event clearing member defaults exhaust the guaranty fund; however, the total amount available would be reduced by the defaulted clearing members' assessment obligations since they would no longer be able to satisfy their obligations.

47

The following shows the available assets for the interest rate swap financial safeguard package at December 31, 2020 in the event of a payment default by a clearing firm that clears interest rate swap contracts, after first utilizing the defaulting firm's available assets:

(in millions)	Clearing House Available Assets
Designated corporate contributions for interest rate swap contracts(1)	$	150.0
Guaranty fund contributions(2)	3,392.1
Assessment powers(3)	1,089.5

_______________

(1)Our clearing house designates $150.0 million of corporate contributions to satisfy a clearing firm default in the event that the defaulting clearing firm's guaranty contributions and performance bonds do not satisfy the deficit.

(2)Guaranty fund contributions of clearing firms for interest rate swap contracts include guaranty fund contributions required of those clearing firms.

(3)In the event of a clearing firm default, if a loss continues to exist after the utilization of the assets of the defaulted firm, our corporate contribution and the non-defaulting firms' guaranty fund contributions, we would assess non-defaulting clearing members as provided in the rules governing the interest rate swap guaranty fund. Assessment powers are calculated to reflected the potential obligation that each clearing member could be called for based on potential failure of the third and fourth largest clearing.

BrokerTec Americas Matched Principal Business

BrokerTec Americas maintains a matched principal business, where it serves as a fully matched counterparty to offsetting positions entered into by clients on its electronic trading platform to facilitate anonymity and access to clearing and settlement. BrokerTec Americas uses Fixed Income Clearing Corporation (FICC), a third-party central clearing house as well as a third-party clearing bank for the settlement of transactions and is required to post short-term margin requirements twice a day that can vary based on the size of unsettled transactions and any adverse market changes. At December 31, 2020, the balance of the collateral at FICC was $100.1 million, which was included in other current assets on the consolidated balance sheet.

Without sufficient funds to meet its obligations, BrokerTec Americas could be exposed to risk of breach of contract with the counterparties and the inability to continue as a member of the third-party central clearing house. Transactions with clearing house members are typically confirmed and novated shortly after execution, at which point the clearing house assumes the risk of settlement. For transactions with counterparties that are not members of the third-party clearing house, settlement typically occurs on the day following execution and, prior to settlement, BrokerTec Americas is exposed to the risk of loss in the event a counterparty fails to meet its obligations. If that were to occur, BrokerTec Americas would have the right to cover or liquidate the open position but could incur a loss as a result of market movements.

Foreign Currency Exchange Rate Risk

Foreign Currency Transaction Risk

We have foreign currency transaction risk related to changes in exchange rates on monetary assets, liabilities, revenues and expenses held at subsidiaries where those balances and activity are denominated in a currency other than the subsidiary's functional currency. Gains and losses on foreign currency transactions result primarily from cash, debt and other monetary assets, liabilities, revenues and expenses denominated in British pounds, euros and Japanese yen.

Aggregate transaction losses for 2020, 2019 and 2018 were $9.3 million, $7.2 million and $73.6 million, respectively. We expect the foreign currency gain/loss to continue to fluctuate as long as we continue to hold monetary assets and liabilities at those subsidiaries. Brexit continues to generate economic and political uncertainty throughout the world, particularly throughout the U.K. and the E.U. This uncertainty could potentially lead to significant volatility with foreign currency exchange rates, which could result in additional foreign currency gain/loss.

Foreign Currency Translation Risk

We have foreign currency translation risk related to the translation of our foreign subsidiaries' assets, liabilities, revenues and expenses from their respective functional currencies to the U.S. dollar at each reporting date. Fluctuations in exchange rates may impact the amount of assets, liabilities, revenues and expenses we report on our consolidated balance sheets and consolidated statements of income. The financial statements of those foreign subsidiaries with functional currencies other than the U.S. dollar are translated into U.S. dollars using a current exchange rate. Gains and losses resulting from this translation are recognized as a foreign currency translation adjustment within accumulated other comprehensive income, which is a component of shareholders' equity and comprehensive income. Aggregate translation gains (losses), net of tax, for 2020, 2019 and 2018 were $134.3 million, $(0.6) million and $(2.5) million, respectively.

48

Foreign Currency Exchange Risk Related to Customer Collateral

A portion of performance bond deposits is denominated in various foreign currencies. We mark-to-market all deposits daily and require payment from clearing firms whose collateral has lost value due to changes in foreign currency rates and price. Therefore, our exposure to foreign currency risk related to performance bond deposits is considered minimal and is not expected to be material to our financial condition or operating results.

CME Group and its subsidiaries are referred to collectively as “the company” in the notes to the consolidated financial statements.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation. The accompanying consolidated financial statements are prepared in accordance with accounting principles generally accepted in the U.S. and include the accounts of the company and its subsidiaries. All intercompany transactions and balances have been eliminated.

Use of Estimates. The preparation of consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts and the disclosure of contingent amounts on the consolidated financial statements and accompanying notes. Estimates are based on historical experience, where applicable, and assumptions management believes are reasonable under the circumstances. Due to the inherent uncertainty involved with estimates, actual results may differ.

Cash and Cash Equivalents. Cash and cash equivalents consist of cash and highly liquid investments with a maturity of three months or less at the time of purchase.

Financial Investments. The company maintains short-term and long-term investments, classified as equity method investments, equity securities, available-for-sale debt securities, and trading securities. Available-for-sale debt securities are carried at fair value, with unrealized gains and losses, net of deferred income taxes, reported as a component of accumulated other comprehensive income. Trading securities held in connection with non-qualified deferred compensation plans and equity securities are recorded at fair value, with net realized and unrealized gains and losses and dividend income reported as investment income. For equity investments in privately-held entities that do not have a readily determinable fair value, our accounting policy is to utilize the measurement alternative for valuation of these investments, which permits the company to estimate fair value at cost minus impairment, plus or minus changes resulting from observable price movements. Also, the company maintains long-term investments accounted for under the equity method, which requires that the company recognize its share of net income (loss) in the investee as an adjustment to the carrying amount of the investment each reporting period.

The company reviews its investment portfolio at least quarterly as well as whenever facts or circumstances exist which indicate that the carrying value of the investment is greater than its fair value. For investments not carried at fair value, the carrying value of the investment is reduced to its fair value and a corresponding impairment expense is charged to earnings, if events and circumstances indicate that a markdown to fair value is warranted. Declines in the fair value of available-for-sale securities that are deemed to be other-than-temporary are charged to earnings as a realized loss.

Fair Value of Financial Instruments. The company uses a three-level classification hierarchy of fair value measurements that establishes the quality of inputs used to measure fair value. The fair value of a financial instrument is the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value of financial instruments is determined using various techniques that involve some level of estimation and judgment, the degree of which is dependent on the price transparency and the complexity of the instruments.

Derivative Investments. The company occasionally uses derivative instruments to limit exposure to changes in interest rates and foreign currency exchange rates. Derivatives are recorded at fair value on the consolidated balance sheets. For those

58

derivatives that meet the criteria for hedge accounting and are classified as effective cash flow hedges, changes in the fair value of the hedges are deferred in accumulated other comprehensive income. Any realized gains and losses from effective hedges are classified within the same financial statement line item on the consolidated statements of income as the hedge risk. For any hedges no longer deemed effective or for which hedge accounting is not applied, changes in fair value of the derivative instruments are recognized in earnings immediately within other non-operating income (expense). There were no outstanding derivative instruments at December 31, 2020.

Accounts Receivable. Accounts receivable are comprised of trade receivables and unbilled revenue. All accounts receivable are stated at net realizable value. Exposure to losses on receivables for clearing and transaction fees and other amounts owed by clearing and trading firms is dependent on each firm's financial condition. With respect to clearing firms, our credit loss exposure is mitigated by the memberships that collateralize fees owed to the company. The company retains the right to liquidate exchange memberships to satisfy an outstanding receivable. The allowance for doubtful accounts is calculated based on management's assessment of future expected losses over the life of the receivable, historical trends and the current economic environment within which we operate.

Performance Bonds and Guaranty Fund Contributions. Performance bonds and guaranty fund contributions held for clearing firms may be in the form of cash, securities or other non-cash deposits.

Performance bonds and guaranty fund contributions received in the form of cash held by CME may be invested in U.S. government securities, U.S. government agency securities and certain foreign government securities acquired through and held by a bank or broker-dealer subsidiary of a bank, a cash account at the Federal Reserve Bank of Chicago, reverse repurchase agreements secured with highly rated government securities, money market funds or through CME's Interest Earning Facility (IEF) program. Any interest earned on CME investments accrues to CME and is included in investment income on the consolidated statements of income. CME may distribute any interest earned on its investments to the clearing firms at its discretion. Because CME has control of the cash collateral and the benefits and market risks of ownership accrue to CME, cash performance bonds and guaranty fund contributions are reflected on the consolidated balance sheets.

Securities and other non-cash deposits may include U.S. Treasury securities, U.S. government agency securities, Eurobonds, corporate bonds, other foreign government securities and gold bullion. Securities and other non-cash deposits are held in safekeeping by a custodian bank. Interest and gains or losses on securities deposited to satisfy performance bond and guaranty fund requirements accrue to the clearing firm. Because the benefits and risks of ownership accrue to the clearing firm, non-cash performance bonds and guaranty fund contributions are not reflected on the consolidated balance sheets.

Property. Property is stated at cost, less accumulated depreciation and amortization. Depreciation and amortization are calculated using the straight-line method, generally over two to thirty-nine years. Property and equipment are depreciated over their estimated useful lives. Leasehold improvements are amortized over the shorter of the remaining term of the respective lease to which they relate or the remaining useful life of the leasehold improvement. Land is reported at cost. Internal and external costs incurred in developing or obtaining computer software for internal use which meet the requirements for capitalization are amortized on a straight-line basis over the estimated useful life of the software, generally two to four years, but up to eight years for certain trading and clearing applications, depending upon expected useful lives.

Leases. The company accounts for our leases of office space as operating leases. Landlord allowances are recorded as a direct reduction to the capitalized lease asset, which is reported in other assets and amortized to rent expense over the term of the lease. The associated lease liability represents the present value of lease payments remaining in the lease term and is recorded within current and other liabilities depending upon the balance sheet classification of the payment obligations as short-term or long-term. For sale leaseback transactions, the company evaluates the sale and the lease arrangement based on the company's conclusion as to whether control of the underlying asset has been transferred and recognizes the sale leaseback as either a sale transaction or under the financing method, which requires the asset to remain on the consolidated balance sheets throughout the term of the lease and the proceeds to be recognized as a financing obligation. A portion of the lease payments is recognized as a reduction of the financing obligation and a portion is recognized as interest expense based on an imputed interest rate.

Goodwill and Other Intangible Assets. Goodwill represents the excess of the purchase price over the fair value of the net assets acquired in a business combination. The company reviews goodwill and indefinite-lived intangible assets for impairment at least quarterly and whenever events or circumstances indicate that their carrying values may not be recoverable. The company may test goodwill quantitatively for impairment by comparing the carrying value of a reporting unit to its estimated fair value. Estimating the fair value of a reporting unit involves significant judgments inherent in the analysis including estimating the amount and timing of future cash flows and the selection of appropriate discount rates and long-term growth rate assumptions. Changes in these estimates and assumptions could materially affect the determination of fair value for the reporting unit. If the carrying amount exceeds fair value, an impairment loss is recorded. In certain circumstances, goodwill may be reviewed qualitatively for indications of impairment without utilizing valuation techniques to estimate fair value.

The company performs an impairment assessment of indefinite-lived intangible assets at least quarterly or whenever events or circumstances indicate that their carrying values may not be recoverable. If the indefinite-lived intangible asset carrying value

59

exceeds its fair value, an impairment loss is recognized in an amount equal to that excess. Estimating the fair value of indefinite-lived intangible assets involves the use of valuation techniques that rely on significant estimates and assumptions including forecasted revenue growth rates, forecasted allocations of expense and risk-adjusted discount rates. Changes in these estimates and assumptions could materially affect the determination of fair value for indefinite-lived intangible assets. In certain circumstances, indefinite-lived intangible assets may be reviewed qualitatively for indications of impairment without utilizing valuation techniques to estimate fair value.

Intangible assets subject to amortization are also assessed for impairment at least quarterly or when indicated by a change in economic or operational circumstances. The impairment assessment of these assets requires management to first compare the carrying value of the amortizing asset to undiscounted net cash flows. If the carrying value exceeds the undiscounted net cash flows, management is then required to estimate the fair value of the assets and record an impairment loss for the excess of the carrying value over the fair value. In connection with this impairment assessment, management also challenges the useful lives of our amortizing intangible assets.

Business Combinations. The company accounts for business combinations using the acquisition method. The method requires the acquirer to recognize the assets acquired, liabilities assumed, and any non-controlling interest in the acquiree at the acquisition date, measured at their fair values as of that date. The company may use independent valuation services to assist in determining the estimated fair values.

Employee Benefit Plans. The company recognizes the funded status of defined benefit postretirement plans on its consolidated balance sheets. Changes in that funded status are recognized in the year of change in other comprehensive income (loss). Plan assets and obligations are measured at year end. The company recognizes future changes in actuarial gains and losses and prior service costs in the year in which the changes occur through accumulated other comprehensive income (loss).

Foreign Currency Translation. Foreign currency denominated assets and liabilities are re-measured into the functional currency using period-end exchange rates. Gains and losses from foreign currency transactions are included in other expense on the accompanying consolidated statements of income. When the functional currency differs from the reporting currency, revenues and expenses of foreign subsidiaries are translated from their functional currencies into U.S. dollars using weighted-average exchange rates while their assets and liabilities are translated into U.S. dollars using period-end exchange rates. Gains and losses resulting from foreign currency translations are included in accumulated other comprehensive income (loss) within shareholders' equity.

Revenue Recognition. Revenue recognition policies for specific sources of revenue are discussed below.

Clearing and Transaction Fees. Clearing and transaction fees include per-contract charges for trade execution, clearing, trading on the company's electronic trading platforms, portfolio reconciliation and compression services, risk mitigation, and other fees. Fees are charged at various rates based on the product traded, the method of trade, the exchange trading privileges of the customer making the trade and the type of contract. The majority of our clearing and transaction fees are recognized as revenue when a buy and sell order are matched. Therefore, unfilled or canceled buy and sell orders have no impact on revenue. On occasion, the customer's exchange trading privileges may not be properly entered by the clearing firm and incorrect fees are charged for the transactions. When this information is corrected within the time period allowed by the company, a fee adjustment is provided to the clearing firm. A reserve is established for estimated fee adjustments to reflect corrections to customer exchange trading privileges. The reserve is based on the historical pattern of adjustments processed as well as specific adjustment requests. The company believes the allowances are adequate to cover estimated adjustments.

Market Data and Information Services. Market data and information services represent revenue earned for the dissemination of market information. Revenues are accrued each month based on the number of devices reported by vendors or over a straight line basis in accordance with the market data subscription contract term. The company conducts periodic examinations of the number of devices reported and assesses additional fees as necessary. On occasion, customers will pay for services in a lump sum payment; however, revenue is recognized as services are provided.

Other Revenues. Other revenues include access and communication fees, fees for collateral management, equity membership subscription fees and fees for trade order routing through agreements from various strategic relationships as well as other services to customers. Revenue is recognized as services are provided.

Concentration of Revenue. One clearing firm represented at least 10% of the company's clearing and transaction fee revenue in 2020. No individual clearing firm represented at least 10% of our clearing and transaction fees in 2019. One clearing firm represented 10% of the company's clearing and transaction fee revenue in 2018. Should a clearing firm withdraw from the company, management believes that the customer portion of that firm's trading activity would likely transfer to another clearing firm. Therefore, management does not believe that the company is exposed to significant risk from the ongoing loss of revenue received from a particular clearing firm.

60

The two largest resellers of market data represented approximately 35% of market data and information services revenue in 2020, 37% in 2019, and 41% in 2018. Should one of these vendors no longer subscribe to the company's market data, management believes that the majority of that firm's customers would likely subscribe to the market data through another reseller. Therefore, management does not believe that the company is exposed to significant risk from a loss of revenue received from any particular market data reseller.

Share-Based Payments. The company accounts for share-based payments at fair value, which is based on the grant date price of the equity awards issued. The company recognizes expense relating to stock-based compensation on an accelerated basis. As a result, the expense associated with each vesting date within a stock grant is recognized over the period of time that each portion of that grant vests. Forfeitures are recognized in the period in which they occur.

Marketing Costs. Marketing costs are incurred for the production and communication of advertising as well as other marketing activities. These costs are expensed when incurred, except for costs related to the production of broadcast advertising, which are expensed when the first broadcast occurs.

Income Taxes. Deferred income taxes arise from temporary differences between the tax basis and book basis of assets and liabilities. A valuation allowance is recognized if it is anticipated that some or all of a deferred tax asset may not be realized. The company accounts for uncertainty in income taxes recognized in its consolidated financial statements by using a more-likely-than-not recognition threshold based on the technical merits of the tax position taken or expected to be taken. The company classifies interest and penalties related to uncertain tax positions in income tax expense.

Segment Reporting. The company reports the results of its operations as one operating segment primarily comprised of the businesses of CME, CBOT, NYMEX, COMEX and NEX. The individual operations of the company do not meet the thresholds for reporting separate segment information.

Newly Adopted Accounting Policies. The company adopted the following accounting policies during 2020:

Credit Losses. In June 2016, the FASB issued guidance that changes how credit losses are measured for most financial assets measured at amortized cost and certain other instruments. The standard requires an entity to estimate its lifetime expected credit loss and record an allowance, that when deducted from the amortized cost basis of the financial asset, presents the net amount expected to be collected on the financial asset. This forward-looking expected loss model generally will result in the earlier recognition of allowances for losses. The standard also amends the impairment model for available for sale debt securities and requires entities to determine whether all or a portion of the unrealized loss on an available for sale debt security is a credit loss. Severity and duration of the unrealized loss are no longer permissible factors in concluding whether a credit loss exists. Entities will recognize improvements to estimated credit losses on available for sale debt securities immediately in earnings rather than as interest income over time. The company implemented this standard on January 1, 2020 by recognizing an immaterial cumulative-effect adjustment to the beginning balance of retained earnings.

The company has not experienced significant levels of underpayment or nonpayment by customers and does not expect changes to this trend over the payment terms of our receivables. Exposure to losses on receivables for clearing and transaction fees and other amounts owed by clearing and trading firms is dependent on each firm's financial condition. With respect to clearing firms, the company's credit loss exposure is mitigated by the memberships that collateralize fees owed to the company. The allowance for credit losses on accounts receivable is calculated by evaluating the aging of the company's billings by revenue stream: clearing and transaction, market data, and other. This aging assessment, as well as contemplation of current and anticipated economic factors, including the interest rate environment and pricing levels are the primary considerations that most significantly impact the collectability of accounts receivable. The allowance for accounts receivable is $5.4 million at December 31, 2020.

Defined Pension and Other Postretirement Plans. In August 2018, the FASB issued a standards update that modifies the disclosure requirements for employers that sponsor defined pension or other postretirement plans. The guidance clarifies certain existing disclosures and expands the requirements for others. Disclosures that are not considered cost beneficial are removed by the update. Also, there is a new disclosure requirement to include an explanation of the reasons for significant gains and losses related to changes in the benefit obligation for the period. This guidance is effective for reporting periods ending after December 15, 2020. Adoption of this guidance in December 2020 did not have a material financial statement impact as the changes are disclosure-related only. The company has amended its employee benefit plan disclosures to incorporate the new guidance in footnote 11 of this report.

Income Taxes. In December 2019, the FASB issued an accounting update that is intended to reduce cost and complexity related to accounting for income taxes. The update removes specific exceptions to the general principles for accounting for income taxes. Specifically, it eliminates the need for an entity to analyze whether the following exceptions apply in a given period: incremental approach for intraperiod tax allocation, accounting basis differences when there are ownership changes in foreign investments, and interim period income tax accounting for year-to-date losses that exceed anticipated losses. The update also simplifies the accounting for the following: franchise taxes that are partially based on income, transactions with a government

61

that result in a step up in the tax basis of goodwill, separate financial statements of legal entities that are not subject to tax, and enacted changes in tax laws in interim periods. This update is effective for reporting periods beginning after December 15, 2020. The company early adopted this standard on January 1, 2020. The impact of adoption of this standard was immaterial to the consolidated financial statements.

3. MARKETABLE SECURITIES

The company has equity securities, available-for-sale debt securities and mutual funds classified as marketable securities on our consolidated balance sheets. The amortized cost and fair value of equity securities and available-for-sale debt securities at December 31, 2020 and 2019 were as follows: 

	2020				2019
(in millions)	Amortized Cost		Fair Value		Amortized Cost		Fair Value
Corporate debt securities (1)	$	15.9	$	17.9	$	15.8	$	16.7
Asset-backed security	0.5		0.3		0.5		0.3
Equity securities	—		0.1		—		0.1

4. REVENUE RECOGNITION

The company generates revenue from customers from the following sources:

Clearing and transaction fees. Clearing and transaction fees include electronic trading fees and brokerage commissions, surcharges for privately-negotiated transactions, portfolio reconciliation and compression services, risk mitigation and other volume-related charges for trade contracts. Clearing and transaction fees are assessed upfront at the time of trade execution. As such, the company recognizes the majority of the fee revenue upon successful execution of the trade. The minimal remaining portion of the fee revenue related to settlement activities performed after trade execution is recognized over the short-term period that the contract is outstanding, based on management’s estimates of the average contract lifecycle. These estimates are based on various assumptions to approximate the amount of fee revenue to be attributed to services performed through contract settlement, expiration, or termination. For cleared trades, these assumptions include the average number of days that a contract remains in open interest, contract turnover, average revenue per day, and revenue remaining in open interest at the end of each period.

62

The nature of contracts gives rise to several types of variable consideration, including volume-based pricing tiers, customer incentives associated with market maker programs and other fee discounts. The company includes fee discounts and incentives in the estimated transaction price when there is a basis to reasonably estimate the amount of the fee reduction. These estimates are based on historical experience, anticipated performance, and best judgment at the time. Because of the company's certainty in estimating these amounts, they are included in the transaction price of contracts.

Market data and information services. Market data and information services represent revenue from the dissemination of market data to subscribers, distributors, and other third-party licensees of market data. Pricing for market data is primarily based on the number of reportable devices used as well as the number of subscribers enrolled under the arrangement. Fees for these services are generally billed monthly. Market data services are satisfied over time and revenue is recognized on a monthly basis as the customers receive and consume the benefit of the market data services. However, the company also maintains certain annual license arrangements with one-time upfront fees. The fees for annual licenses are initially recorded as a contract liability and recognized as revenue monthly over the term of the annual period.

Other. Other revenues include certain access and communication fees, fees for collateral management, equity membership subscription fees, and fees for trade order routing through agreements from various strategic relationships. Access and communication fees are charges to customers that utilize various telecommunications networks and communications services. Fees for these services are generally billed monthly and the associated fee revenue is recognized as billed. Collateral management fees are charged to clearing firms that have collateral on deposit with the clearing house to meet their minimum performance bond and guaranty fund obligations on the exchange. These fees are calculated based on daily collateral balances and are billed monthly. This fee revenue is recognized monthly as billed as the customers receive and consume the benefits of the services. We also have an equity membership program which provides equity members the option to substitute a monthly subscription fee for their existing requirement to hold CME Group Class A common stock. Choosing to pay this fee in lieu of holding Class A shares is entirely voluntary and the client's choice. Fee revenue under this program is earned monthly as billed over the contractual term. Pricing for strategic relationships may be driven by customer levels and activity. There are fee arrangements which provide for monthly as well as quarterly payments in arrears. Revenue is recognized monthly for strategic relationship arrangements as the customers receive and consume the benefits of the services.

The following table represents a disaggregation of revenue from contracts with customers for the years ended December 31, 2020, 2019 and 2018:

(in millions)	2020		2019		2018

One-time charges and miscellaneous revenues	6.2		14.9		9.1
Total revenues	$	4,883.6	$	4,868.0	$	4,309.4

The timing of revenue recognition, billings and cash collections results in billed accounts receivable, and customer advances and deposits (contract liabilities) on the consolidated balance sheets. Certain fees for transactions, annual licenses, and other revenue arrangements are billed upfront before revenue is recognized, which results in the recognition of contract liabilities. These liabilities are recognized on the consolidated balance sheets on a contract-by-contract basis upon commencement of services under the customer contract. Upfront customer payments are recognized as revenue over time as the obligations under

63

the contracts are satisfied. Changes in the contract liability balances during 2020 were not materially impacted by any other factors. Contract liabilities are presented within other current liabilities. The balance of contract liabilities was $37.3 million and $42.6 million as of December 31, 2020 and 2019, respectively.

5. PERFORMANCE BONDS AND GUARANTY FUND CONTRIBUTIONS

The clearing house clears and guarantees the settlement of contracts traded in the futures and options and interest rate swap markets. In its guarantor role, the clearing house has precisely equal and offsetting claims to and from clearing firms on opposite sides of each contract, standing as an intermediary on every contract cleared. In the U.S., clearing firm positions are held according to Commodity and Futures Trading Commission (CFTC) regulatory account segregation standards. To the extent that funds are not otherwise available to satisfy an obligation under the applicable contract, the clearing house bears counterparty credit risk in the event that future market movements create conditions that could lead to clearing firms failing to meet their obligations to the clearing house. The clearing house reduces the exposure through risk management programs that include initial and ongoing financial standards for designation as a clearing firm, performance bond requirements, daily mark-to-market, mandatory guaranty fund contributions and intra-day monitoring.

Each clearing firm is required to deposit and maintain balances in the form of cash, U.S. government securities, certain foreign government securities, bank letters of credit or other approved collateral investments to satisfy performance bond and guaranty fund requirements. All non-cash deposits and certain cash deposits with foreign currency exposure are marked-to-market and haircut on a daily basis. Securities deposited by the clearing firms are not reflected on the consolidated financial statements and the clearing house does not earn any interest on these deposits. These balances may fluctuate significantly over time due to collateral investment choices available to clearing firms and changes in the amount of contributions required.

The clearing house marks-to-market open positions at least once a day (twice a day for futures and options contracts), and requires payment from clearing firms whose positions have lost value and make payments to clearing firms whose positions have gained value. The clearing house has the capability to mark-to-market more frequently as market conditions warrant.

Under the extremely unlikely scenario of simultaneous default by every clearing firm who has open positions with unrealized losses, the maximum exposure at the time of default related to positions other than interest rate swap contracts would be one half day of changes in fair value of all open positions, before considering the clearing house's ability to access defaulting clearing firms' collateral deposits. For cleared interest rate swap contracts, the maximum exposure at the time of default related to the clearing house's guarantee would be one full day of changes in fair value of all open positions, before considering the clearing house's ability to access defaulting clearing firms' collateral. The clearing firms' collateral requirements are sized to cover at least one day of anticipated price movements. During 2020, the clearing house transferred an average of approximately $4.7 billion a day through the clearing system for settlement from clearing firms whose positions had lost value to clearing firms whose positions had gained value. The clearing house reduces its exposure through maintenance performance bond requirements and guaranty fund contributions. For futures and options products, the clearing firms' collateral requirements are sized to cover at least one day of anticipated price movements. For cleared swap products, the clearing firms' collateral requirements are sized to cover at least five days of anticipated price movements. Management has assessed the fair value of the company's settlement guarantee liability by taking the following factors into consideration: the design and operations of the clearing risk management process, the financial safeguard packages in place, historical evidence of default by a clearing member and the estimated probability of potential payouts by the clearing house. Based on the assessment performed, management estimates the guarantee liability to be nominal and therefore has not recorded any liability at December 31, 2020.

At December 31, 2020 and 2019, performance bond and guaranty fund contribution assets on the consolidated balance sheets included cash as well as U.S. government agency securities with maturity dates of 90 days or less. U.S. government agency securities are purchased by the clearing house, at its discretion, using cash collateral. The benefits, including interest earned, and risks of ownership accrue to the clearing house. Interest earned is included in investment income on the consolidated statements of income. The U.S. government agency securities held at December 31, 2019 matured during the first quarter of 2020. These securities are marked to fair value on the consolidated balance sheets.

The amortized cost and fair value of these securities at December 31, 2020 and 2019 were as follows.

	2020				2019
(in millions)	Amortized Cost		Fair Value		Amortized Cost		Fair Value
U.S. government agency securities	$	—	$	—	$	898.2	$	898.2

CME has been designated as a systemically important financial market utility by the Financial Stability Oversight Council and is authorized to maintain cash accounts at the Federal Reserve Bank of Chicago. At December 31, 2020 and 2019, the clearing house maintained $76.3 billion and $22.9 billion, respectively, within the cash accounts at the Federal Reserve Bank of Chicago. The cash deposited at the Federal Reserve Bank of Chicago is included within performance bonds and guaranty fund contributions on the consolidated balance sheets.

64

CME and The Options Clearing Corporation (OCC) have a perpetual cross-margin arrangement, whereby a clearing firm may maintain a cross-margin account in which a clearing firm's positions in certain equity index futures and options are combined with certain positions cleared by OCC for purposes of calculating performance bond requirements. The performance bond deposits are held jointly by CME and OCC. Cross-margin cash, securities and letters of credit jointly held with OCC under the cross-margin agreement are reflected at 50% of the total, or CME's proportionate share per that agreement. If a participating firm defaults, the gain or loss on the liquidation of the firm's open position and the proceeds from the liquidation of the cross-margin account would be allocated 50% each to CME and OCC. In the event of a remaining loss, CME would first apply assets of the defaulting clearing firm to satisfy its payment obligation. These assets include the defaulting firm's guaranty fund contributions, performance bonds and any other available assets, such as assets required for clearing membership and any associated trading rights. In addition, the clearing house would make a demand for payment pursuant to any applicable guarantee, if any, provided to it by the parent company of the clearing firm. Thereafter, if the payment default remains unsatisfied, the clearing house would use its corporate contributions designated for the respective financial safeguard package. The clearing house would then use guaranty fund contributions of other clearing firms within the respective financial safeguard package and funds collected through an assessment against solvent clearing firms within the respective financial safeguard package to satisfy the deficit.

In addition, CME has perpetual cross-margin agreements with Fixed Income Clearing Corporation (FICC) whereby the clearing firms' offsetting positions with CME and FICC are subject to reduced performance bond requirements. Clearing firms maintain separate performance bond deposits with each clearing house, but depending on the net offsetting positions between CME and FICC, each clearing house may reduce that firm's performance bond requirements. In the event of a firm default, the total liquidation net gain or loss on the firm's offsetting open positions and the proceeds from the liquidation of the performance bond collateral held by each clearing house's supporting offsetting positions would be divided evenly between CME and FICC. Additionally, if, after liquidation of all the positions and collateral of the defaulting firm at each respective clearing organization, and taking into account any cross-margining loss sharing payments, any of the participating clearing organizations has a remaining liquidating surplus, and any other participating clearing organization has a remaining liquidating deficit, any additional surplus from the liquidation would be shared with the other clearing house to the extent that it has a remaining liquidating deficit. Any remaining surplus funds would be passed to the bankruptcy trustee. In the event of a remaining loss, CME would first apply assets of the defaulting clearing firm to satisfy its payment obligation. These assets include the defaulting firm's guaranty fund contributions, performance bonds and any other available assets, such as assets required for clearing membership and any associated trading rights. In addition, the clearing house would make a demand for payment pursuant to any applicable guarantee, if any, provided to it by the parent company of the clearing firm. Thereafter, if the payment default remains unsatisfied, the clearing house would use its corporate contributions designated for the respective financial safeguard package. The clearing house would then use guaranty fund contributions of other clearing firms within the respective financial safeguard package and funds collected through an assessment against solvent clearing firms within the respective financial safeguard package to satisfy the deficit.

Each clearing firm for futures and options is required to deposit and maintain specified guaranty fund contributions in the form of cash or U.S. Treasury securities (base guaranty fund). In the event that performance bonds, guaranty fund contributions and other assets required to support clearing membership of a defaulting clearing firm are inadequate to fulfill that clearing firm's outstanding financial obligation, the base guaranty fund for contracts other than interest rate swaps is available to cover potential losses after first utilizing $100.0 million of corporate contributions designated by CME to be used in the event of a default of a clearing firm for the base guaranty fund.

The clearing house maintains a separate guaranty fund to support the clearing firms that clear interest rate swap products (cleared interest rate swaps contract guaranty fund). The funds for interest rate swaps are independent of the base guaranty fund and are isolated to clearing firms for products in the respective asset class. Each clearing firm for cleared interest rate swaps is required to deposit and maintain specified guaranty fund contributions in the form of cash or U.S. Treasury securities. In the event that performance bonds, guaranty fund contributions and other assets required to support clearing membership of a defaulting clearing firm for cleared interest rate swap contracts are inadequate to fulfill that clearing firm's outstanding financial obligation, the interest rate swaps contracts guaranty fund is available to cover potential losses after first utilizing $150.0 million of corporate contributions designated by CME to be used in the event of a default of a cleared interest rate swap clearing firm.

CME maintains a 364-day multi-currency line of credit with a consortium of domestic and international banks to be used in certain situations by the clearing house. CME 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 of the collateral), or in the event of a temporary disruption with the domestic payments system that would delay payment of settlement variation between CME and its clearing firms. Clearing firm guaranty fund contributions received in the form of cash or U.S. Treasury securities as well as the performance bond assets of a defaulting firm can be used to collateralize the facility. The line of credit provides for borrowings of up to $7.0 billion. At December 31, 2020, guaranty fund contributions available for clearing firms were $8.0 billion. CME has the option to request an increase in the line from $7.0 billion to $10.0 billion, subject to the approval of

65

participating banks. In addition to the 364-day fully secured, committed multi-currency line of credit, the company also has the option to use the $2.4 billion multi-currency revolving senior credit facility to provide liquidity for the clearing house in the unlikely event of default.

The clearing house is required under the Commodity Exchange Act in the U.S. to segregate cash and securities deposited by clearing firms from its customers. In addition, the clearing house requires segregation of all funds deposited by its clearing firms from operating funds.

Cash and non-cash deposits held as performance bonds and guaranty fund contributions at fair value at December 31, 2020 and 2019 were as follows:

	2020				2019
(in millions)	Cash		Non-Cash Deposits and IEF Funds (1)		Cash		Non-Cash Deposits and IEF Funds (1)

  _______________

(1) IEF funds include customer-directed investments in IEF funds that are not included on the consolidated balance sheets.

Cross-margin arrangements include collateral for the cross-margin accounts with OCC and FICC.

Cash performance bonds may include intraday settlement, if any, that is owed to the clearing firms and paid the following business day. The balance of intraday settlements was $134.7 million and $133.8 million at December 31, 2020 and 2019, respectively. Intraday settlements may be invested on an overnight basis and are offset by an equal liability owed to clearing firms.

In addition to cash, securities and other non-cash deposits, irrevocable letters of credit may be used as performance bond deposits for clearing firms. At December 31, 2020 and 2019 these letters of credit, which are not included in the accompanying consolidated balance sheets, were as follows:

In 2020, the effective tax rate was higher than the statutory tax rate. The increase to the effective tax rate for the state taxes was partially offset by the foreign-derived intangible income deduction (FDII).

In 2019, the effective tax rate was slightly higher than the statutory tax rate. The increase to the effective tax rate for the state taxes was partially offset by the FDII deduction. Proposed FDII deduction regulations were released in 2019 and as a result, management revised the income tax calculations to reflect the proposed guidance. The benefit recognized in 2019 includes estimates for the deduction for 2018 and 2019.

In 2018, the effective tax rate was higher than the statutory tax rate primarily due to the NEX acquisition impact on state tax expense.

At December 31, 2020 and 2019, deferred income tax assets (liabilities) consisted of the following: 

(in millions)	2020		2019
Deferred Income Tax Assets:
Net operating losses	$	36.8	$	35.9
Accrued expenses, compensation and other	59.1		46.2
Subtotal	95.9		82.1
Valuation allowance	(11.3)		(10.0)
Total deferred income tax assets	84.6		72.1
Deferred Income Tax Liabilities:
Purchased intangible assets	(5,614.9)		(5,654.4)
Property	(45.7)		(23.3)
Total deferred income tax liabilities	(5,660.6)		(5,677.7)
Net Deferred Income Tax Liabilities	$	(5,576.0)	$	(5,605.6)
Reported as:
Net non-current deferred tax assets	$	31.0	$	29.6
Net non-current deferred tax liabilities	(5,607.0)		(5,635.2)
Net Deferred Income Tax Liabilities	$	(5,576.0)	$	(5,605.6)

A valuation allowance is recorded when it is more-likely-than-not that some portion or all of the deferred income tax assets may not be realized. The ultimate realization of the deferred income tax assets depends on the ability to generate sufficient taxable income of the appropriate character in the future and in the appropriate taxing jurisdictions.

At December 31, 2020 and 2019, the company had domestic and foreign income tax loss carry forwards of $190.2 million and $202.1 million, respectively. These amounts primarily related to losses from the acquisition of NEX Group plc, the acquisitions of Swapstream Limited and its affiliates, the acquisition of Pivot, Inc., losses incurred in the operation of various foreign entities and capital losses from the sales of securities. At December 31, 2020 and 2019, the company determined that it was not more-likely-than-not that certain foreign deferred income tax assets will be fully realized.

As a result, valuation allowances of $11.3 million and $10.0 million were recorded at December 31, 2020 and 2019, respectively.

The following is a summary of the company’s unrecognized tax benefits at December 31, 2020, 2019 and 2018:

(in millions)	2020		2019		2018
Gross unrecognized tax benefits	$	328.2	$	388.5	$	396.2
Unrecognized tax benefits, net of tax impacts in other jurisdictions	302.4		359.6		367.9
Unrecognized interest and penalties related to uncertain tax positions	43.6		53.3		63.5
Interest and penalties recognized on the consolidated statements of income	7.7		(1.5)		29.5

The company does not believe it is reasonably possible that within the next twelve months, unrecognized tax benefits will change by a significant amount.

71

A reconciliation of the beginning and ending amounts of gross unrecognized tax benefits is as follows:

(in millions)	2020		2019		2018
Balance at January 1	$	388.5	$	396.2	$	308.8
Additions based on tax positions related to the current year	20.2		30.3		27.2
Unrecognized tax benefits acquired at date of acquisition	—		—		58.4
Additions for tax positions of prior years	3.2		4.7		7.7
Reductions for tax positions of prior years	(10.8)		(8.8)		(0.3)
Reductions resulting from the lapse of statutes of limitations	—		(1.7)		(3.1)
Settlements with taxing authorities	(72.9)		(32.2)		(2.5)
Balance at December 31	$	328.2	$	388.5	$	396.2

The company is subject to U.S. federal income tax as well as income taxes in Illinois and multiple other state, local and foreign jurisdictions.  As of December 31, 2020, substantially all federal and state income tax matters had been concluded through 2007 and 2006, respectively.

11. EMPLOYEE BENEFIT PLANS

Pension Plans. CME maintains a non-contributory defined benefit cash balance pension plan for eligible employees. CME's plan provides for a pay-based credit added to the cash balance account based on age and earnings and includes salary and cash bonuses in the definition of earnings. Employees who have completed a continuous 12-month period of employment and have reached the age of 21 are eligible to participate. Participant cash balance accounts receive an interest credit equal to the greater of the one-year constant maturity yield for U.S. Treasury notes or 4.0%. Participants become vested in their accounts after three years of service. The measurement date used for the plan is December 31.

The following is a summary of the change in projected benefit obligation:

(in millions)	2020		2019
Balance at January 1	$	324.2	$	265.1
Service cost	26.7		19.0
Interest cost	11.7		12.3
Actuarial (gain) loss	25.2		35.9
Benefits paid	(7.5)		(8.1)
Balance at December 31	$	380.3	$	324.2

The actuarial losses recognized as of December 31, 2020 and 2019 are the result of a reduction in the discount rate used to determine the projected benefit obligation as of each year end.

The aggregate accumulated benefit obligation was $350.3 million and $293.1 million at December 31, 2020 and 2019, respectively.

The following is a summary of the change in fair value of plan assets:

(in millions)	2020		2019		2018
Balance at January 1	$	356.9	$	315.8	$	348.0
Actual return on plan assets	38.8		49.2		(17.3)
Benefits paid	(7.5)		(8.1)		(14.9)
Balance at December 31	$	388.2	$	356.9	$	315.8

The plan assets are classified into a fair value hierarchy in their entirety based on the lowest level of input that is significant to each asset or liability’s fair value measurement. Valuation techniques for level 2 assets use significant observable inputs such as quoted prices for similar assets, quoted market prices in inactive markets and other inputs that are observable or can be supported by observable market data.

72

The fair value of each major category of plan assets as of December 31, 2020 and 2019 is indicated below:

(in millions)	2020		2019
Level 2:
Money market funds	$	14.1	$	9.6
Mutual funds:
Fixed income	140.2		155.0
U.S. equity	149.4		121.1
Foreign equity	84.5		71.2
Total	$	388.2	$	356.9

At December 31, 2020 and 2019, the fair value of pension plan assets exceeded the projected benefit obligation by $7.9 million and $32.7 million, respectively, and the excess was recorded as a non-current pension asset in other assets.

CME's funding goal is to have its pension plan 100% funded at each year-end on a projected benefit obligation basis, while also satisfying any minimum required contribution and obtaining the maximum tax deduction. Year-end 2020 assumptions have been used to project the assets and liabilities from December 31, 2020 to December 31, 2021. The company anticipates based on this projection that an additional contribution of $6.0 million in 2021 will be necessary for it to meet its funding goal. However, the amount of the actual contribution is contingent on various factors, including the actual rate of return on the plan assets during 2021 and the December 31, 2021 discount rate.

The components of net pension expense and the assumptions used to determine the end-of-year projected benefit obligation and net pension expense in aggregate at December 31, 2020, 2019 and 2018 are indicated below:

(in millions)	2020			2019			2018
Components of Net Pension Expense:
Service cost	$	26.7		$	19.0		$	19.1
Interest cost	11.7			12.3			10.5
Expected return on plan assets	(21.0)			(20.0)			(22.1)
Recognized net actuarial loss	4.8			5.0			2.7
Net Pension Expense	$	22.2		$	16.3		$	10.2
Assumptions Used to Determine End-of-Year Benefit Obligation:
Discount rate	2.70		%	3.40		%	4.40		%
Rate of compensation increase	4.00			5.00			5.00
Cash balance interest crediting rate	4.00			4.00			4.00
Assumptions Used to Determine Net Pension Expense:
Discount rate	3.40		%	4.40		%	3.70		%
Rate of compensation increase	5.00			5.00			5.00
Expected return on plan assets	6.00			6.50			6.50
Interest crediting rate	4.00			4.00			4.00

The discount rate for the plan was determined based on the market value of a theoretical settlement bond portfolio. This portfolio consisted of U.S. dollar denominated Aa-rated corporate bonds across the full maturity spectrum. A single equivalent discount rate was determined to align the present value of the required cash flow with that settlement value. The resulting discount rate was reflective of both the current interest rate environment and the plan's distinct liability characteristics.

The basis for determining the expected rate of return on plan assets for the plan is comprised of three components: historical returns, industry peers and forecasted return. The plan's total return is expected to equal the composite performance of the security markets over the long term. The security markets are represented by the returns on various domestic and international stock, bond and commodity indexes. These returns are weighted according to the allocation of plan assets to each market and measured individually.

73

The overall objective of the plan is to achieve required long-term rates of return in order to meet future benefit payments. The component of the investment policy for the plan that has the most significant impact on returns is the asset mix. The asset mix has a minimum and maximum range depending on asset class. The plan assets are diversified to minimize the risk of large losses by any one or more individual assets. Such diversification is accomplished, in part, through the selection of asset mix and investment management. The asset allocation for the plan, by asset category, at December 31, 2020 and 2019 was as follows:

	2020		2019
Fixed income	36.1	%	43.5	%
Money market funds	3.6		2.7
U.S. equity	38.5		33.9
Foreign equity	21.8		19.9

For 2021, management expects the fixed income asset class to remain at approximately 50% of the portfolio. The target allocation for the U.S. equity asset class is expected to range from 15% to 45% of the portfolio and the target allocation for the foreign equity asset class is expected to range from approximately 10% to 30% of the portfolio.

At times, the company may determine that it is necessary to place some assets in cash equivalent investments in order to pay expected plan liabilities. Given this, the actual asset allocation for the plan may not fall within the target allocation ranges from time to time.

According to the plan's investment policy, the plan is not allowed to invest in securities that compromise independence, short sales of securities directly owned by the plan, securities purchased on margin or other uses of borrowed funds, derivatives not used for hedging purposes, restricted stock or illiquid securities or any other transaction prohibited by employment laws. If the plan directly invests in short-term and long-term debt obligations, the investments are limited to obligations rated at the highest rating category by Standard & Poor's or Moody's.

The pre-tax balance and activity of actuarial losses for the pension plan, which are included in other comprehensive income (loss), for 2020 are as follows:

(in millions)	Actuarial Loss
Balance at January 1	$	75.2
Unrecognized net loss	7.3
Recognized as a component of net pension expense	(4.8)
Balance at December 31	$	77.7

At December 31, 2020, anticipated benefit payments from the plan in future years are as follows:

(in millions)
2021	$	25.3
2022	26.2
2023	27.4
2024	28.4
2025	29.3
2026-2030	154.5

Savings Plans. CME maintains a defined contribution savings plan pursuant to Section 401(k) of the Internal Revenue Code, whereby all U.S. employees are participants and have the option to contribute to this plan. CME matches employee contributions up to 3% of the employee's base salary and may make additional discretionary contributions.

In addition to the plan for U.S. employees, the company maintains defined contribution savings plans for employees in international locations, including employees for NEX beginning on November 3, 2018.

Aggregate expense for all of the defined contribution savings plans amounted to $27.7 million, $23.6 million and $13.8 million in 2020, 2019 and 2018, respectively.

CME Non-Qualified Plans. CME maintains non-qualified plans, under which participants may make assumed investment choices with respect to amounts contributed on their behalf. Although not required to do so, CME invests such contributions in assets that mirror the assumed investment choices. The balances in these plans are subject to the claims of general creditors of the company and totaled $82.6 million and $66.1 million at December 31, 2020 and 2019 respectively. Although the value of the plans is recorded as an asset in marketable securities on the consolidated balance sheets, there is an equal and offsetting

74

liability. The investment results of these plans have no impact on net income as the investment results are recorded in equal amounts to both investment income and compensation and benefits expense. The non-qualified plans include the following:

Supplemental Savings Plan. CME maintains a supplemental plan to provide benefits for employees who have been impacted by statutory limits under the provisions of the qualified pension and savings plan. Employees in this plan are subject to the vesting requirements of the underlying qualified plans.

Deferred Compensation Plan. A deferred compensation plan is maintained by CME, under which eligible employees and members of the board of directors may contribute a percentage of their compensation and defer income taxes thereon until the time of distribution.

COMEX Members' Retirement Plan and Benefits. COMEX maintains a non-qualified retirement and benefit plan under the COMEX Members' Retirement Plan and Benefits plan (MRRP). This plan provides benefits to certain members of the COMEX division based on long-term membership, and participation is limited to individuals who were COMEX division members prior to NYMEX's acquisition of COMEX in 1994. No new participants were permitted into the plan after the date of this acquisition. All benefits to be paid under the MRRP are based on reasonable actuarial assumptions which are based upon the amounts that are available and are expected to be available to pay benefits. There were no contributions to the plan in 2020, 2019 and 2018. At December 31, 2020 and 2019, the obligation for the MRRP totaled $15.7 million and $16.5 million, respectively. Assets with a fair value of $19.0 million and $19.3 million have been allocated to this plan at December 31, 2020 and 2019, respectively, and are included in marketable securities and cash and cash equivalents on the consolidated balance sheets. The balances in this plan are subject to the claims of general creditors of COMEX.

12. LEASES AND OTHER COMMITMENTS

Leases. The company has operating leases for datacenters and corporate offices. The operating leases have remaining lease terms of up to 17 years, some of which include options to extend or renew the leases for up to an additional five years, and some of which include options to early terminate the leases in less than 12 months. Management evaluates the exercisability of these options at least quarterly in order to determine whether the contract term must be reassessed. For a small number of the leases, primarily the international locations, management's approach is to enter into short-term leases for a lease term of 12 months or less in order to provide for greater flexibility in the local environment. For certain office spaces, the company has entered into arrangements to sublease excess space to third parties, while the original lease contract remains in effect with the landlord.

The company also has one finance lease, which is related to the sale of our datacenter in March 2016. In connection with the sale, the company leased back a portion of the property. The sale leaseback transaction was recognized under the financing method and not as a sale leaseback arrangement.

The right-of-use lease asset is recorded within other assets, and the present value of the lease liability is recorded within other liabilities (segregated between short-term and long-term) on the consolidated balance sheets. The discount rate applied to the lease payments represents the company's incremental borrowing rate. The company has elected to utilize the short-term lease exception as prescribed in the leasing standard, such that the company has not capitalized on the balance sheet a lease asset or lease liability associated with leases with terms of 12 months or less from the commencement date.

13. CONTINGENCIES

Legal and Regulatory Matters. 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 or aggregate basis will not have a material impact on its consolidated financial position or results of operations.

No accrual was required for contingent legal and regulatory matters as none were probable and estimable as of December 31, 2020 and 2019.

Intellectual Property Indemnifications. Certain agreements with customers and other third parties related to accessing the CME Group 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.

14. GUARANTEES

Mutual Offset Agreement. CME and Singapore Exchange Limited (SGX) maintain a mutual offset agreement with a current term through May 2023. 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 after May 2023 unless either party provides advance notice of its intent to terminate. CME can maintain collateral in the form of irrevocable, standby letters of credit. At December 31, 2020, CME was contingently liable to SGX on irrevocable letters of credit totaling $310.0 million. CME also maintains a $350.0 million line of credit to meet its obligations under this agreement. 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. Management has assessed the fair value of the company's guarantee liability under this mutual offset agreement by taking the following factors into consideration: the design and operations of the clearing risk management process, the financial safeguard packages in place, historical evidence of default by a clearing member and the estimated probability of potential payouts by the clearing house. Based on the assessment performed, management estimates the guarantee liability to be nominal and therefore has not recorded any liability at December 31, 2020.

Family Farmer and Rancher Protection Fund. In 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 has an aggregate 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 this amount, 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 zero and therefore has not recorded any liability at December 31, 2020.

15. CAPITAL STOCK

Associated Trading Rights. Members of CME, CBOT, NYMEX and COMEX own or lease trading rights which entitle them to access open outcry trading, discounts on trading fees and the right to vote on certain matters as provided for by the rules of the particular exchange and CME Group's or the subsidiary's organizational documents. Each class of CME Group Class B common stock is associated with a membership in a specific division for trading at CME. A CME trading right is a separate asset that is not part of or evidenced by the associated share of Class B common stock of CME Group. The Class B common stock of CME Group is intended only to ensure that the Class B shareholders of CME Group retain rights with respect to the election of six members to the board of directors and approval rights with respect to the core rights described below.

Trading rights at CBOT are evidenced by Class B memberships in CBOT, at NYMEX by Class A memberships in NYMEX and at COMEX by COMEX Division Memberships. Members of CBOT, NYMEX and COMEX do not have any rights to elect members of the board of directors and are not entitled to receive dividends or other distributions on their memberships or trading permits.

Core Rights. Holders of CME Group Class B common shares have the right to approve changes in specified rights relating to the trading privileges at CME associated with those shares. These core rights relate primarily to trading right protections, certain trading fee protections and certain membership benefit protections. Votes on changes to these core rights are weighted by class. Each class of Class B common stock has the following number of votes on matters relating to core rights: Class B-1, six votes per share; Class B-2, two votes per share; Class B-3, one vote per share; and Class B-4, 1/6th of one vote per share. The approval of a majority of the votes cast by the holders of shares of Class B common stock is required in order to approve any changes to core rights. Holders of shares of Class A common stock do not have the right to vote on changes to core rights.

Voting Rights. With the exception of the matters reserved to holders of CME Group Class B common stock, holders of CME Group common stock vote together on all matters for which a vote of common shareholders is required. In these votes, each holder of shares of Class A or Class B common stock of CME Group has one vote per share.

Transfer Restrictions. Each class of CME Group Class B common stock is subject to transfer restrictions contained in the Certificate of Incorporation of CME Group. These transfer restrictions prohibit the sale or transfer of any shares of Class B common stock separate from the sale of the associated trading rights.

Election of Directors. The CME Group board of directors is currently comprised of 23 members. Holders of Class B-1, Class B-2 and Class B-3 common stock have the right to elect six directors, of which three are elected by Class B-1 shareholders, two are elected by Class B-2 shareholders and one is elected by Class B-3 shareholders. The remaining directors are elected by the Class A and Class B shareholders voting as a single class.

Dividends. Holders of Class A and Class B common stock of CME Group are entitled to receive proportionately such dividends, if any, as may be declared by the CME Group board of directors.

CME Group Omnibus Stock Plan. CME Group has adopted an Omnibus Stock Plan under which stock-based awards may be made to employees. A total of 40.2 million Class A common stock shares have been reserved for awards under the plan. Awards totaling 25.0 million shares have been granted and are outstanding or have been exercised under this plan at December 31, 2020 (note 16).

Director Stock Plan. CME Group has adopted a Director Stock Plan under which awards are made to non-executive directors as part of their annual compensation. A total of 625,000 Class A shares have been reserved under this plan, and approximately 417,000 shares have been awarded through December 31, 2020.

Employee Stock Purchase Plan. CME Group has adopted an Employee Stock Purchase Plan (ESPP) under which employees may purchase Class A shares at 90% of the market value of the shares using after-tax payroll deductions. A total of 500,000 Class A shares have been reserved under this plan, of which approximately 353,000 shares have been purchased through December 31, 2020 (note 16).

16. STOCK-BASED PAYMENTS

CME Group adopted an Omnibus Stock Plan under which stock-based awards may be made to employees. A total of 40.2 million Class A shares have been reserved for awards under the plan. Awards totaling 25.0 million shares have been granted and are outstanding or have been exercised under the plan as of December 31, 2020. Awards granted generally vest over a four-year period, with 25% vesting one year after the grant date and on that same date in each of the following three years.

Total compensation expense for stock-based payments and total income tax benefit recognized on the consolidated statements of income for stock-based awards at December 31, 2020, 2019 and 2018 were as follows:

(in millions)	2020		2019		2018
Compensation expense	$	96.9	$	85.8	$	96.8
Income tax benefit recognized	23.6		27.3		27.5

At December 31, 2020, there was $142.9 million of total unrecognized compensation expense related to employee stock-based compensation arrangements that had not yet vested. The total unrecognized expense is expected to be recognized over a weighted average period of 2.2 years.

Stock options have not been granted since 2012. The following table summarizes stock option activity for 2020. Aggregate intrinsic value is in millions.

	Number of Shares	Weighted Average Exercise Price		Weighted Average Remaining Contractual Life (in years)	Aggregate Intrinsic Value
Outstanding at December 31, 2019	227,084	$	54	1.4	$	33.2

The total intrinsic value of options exercised during 2020, 2019 and 2018 was $16.7 million, $23.1 million and $17.8 million, respectively.

In 2020, the company granted 426,694 shares of restricted Class A common stock and 31,112 shares of restricted stock units. Restricted common stock and restricted stock units generally have a vesting period of two to four years. The fair value related to these grants was $76.9 million, which is recognized as compensation expense on an accelerated basis over the vesting period. Dividends are accrued on restricted Class A common stock and restricted stock units and are paid once the restricted stock vests. In 2020, the company also granted 209,534 performance shares. The fair value related to these grants was $37.2 million, which is recognized as compensation expense on a straight-lined basis over the vesting period. The vesting of these shares is contingent on meeting stated performance or market conditions, generally measured over a three year period.

The following table summarizes restricted stock, restricted stock units, and performance shares activity for 2020:

	Number of Shares	Weighted Average Grant Date Fair Value
Outstanding at December 31, 2019	1,324,378	$	177
Granted	667,340	171
Vested	(456,295)	148

The total fair value of restricted stock, restricted stock units, and performance shares that vested during 2020, 2019 and 2018 was $79.4 million, $77.7 million and $76.6 million, respectively.

Under the ESPP, eligible employees may acquire shares of Class A common stock using after-tax payroll deductions made during consecutive offering periods of approximately six months in duration. Shares are purchased at the end of each offering period at a price of 90% of the closing price of the Class A common stock as reported on the Nasdaq Global Select Market. Compensation expense is recognized on the dates of purchase for the discount from the closing price. In 2020, 2019 and 2018, a total of 44,029, 26,134 and 22,249 shares, respectively, of Class A common stock were issued to participating employees. These shares are subject to a six-month holding period. Annual expense of $0.8 million for the purchase discount was recognized in 2020, $0.5 million was recognized in 2019 and $0.4 million was recognized in 2018.

Non-executive directors receive an annual award of Class A common stock with a value equal to $120,000. Non-executive directors may also elect to receive some or all of the cash portion of their annual stipend, up to $80,000, in shares of stock based on the closing price at the date of distribution. As a result, 17,322 shares, 16,328 shares and 16,640 shares of Class A common stock were issued to non-executive directors during 2020, 2019 and 2018, respectively. These shares are not subject to any vesting restrictions. Expense of $3.1 million, $3.0 million and $2.6 million related to these stock-based payments was recognized for the years ended December 31, 2020, 2019 and 2018, respectively.

18. 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, 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.

81

•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 investments in publicly traded mutual funds, equity securities, U.S. government securities and corporate debt securities 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.

Level 2 assets and liabilities generally consist of asset-backed securities and long-term debt notes. 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 fair values of the long-term debt notes were based on quoted market prices in an inactive market.

Level 3 assets include fixed assets, intangible assets and certain investments that were impaired.

Recurring Fair Value Measurements. Financial assets and liabilities recorded at fair value on the consolidated balance sheets as of December 31, 2020 and 2019 were classified in their entirety based on the lowest level of input that was significant to each asset or liability's fair value measurement.

Financial Instruments Measured at Fair Value on a Recurring Basis:

	December 31, 2020
(in millions)	Level 1		Level 2		Level 3		Total

 _______________

(1) Performance bonds and guaranty fund contributions on the consolidated balance sheet at December 31, 2019 include U.S. government agency securities purchased with cash collateral.

Non-Recurring Fair Value Measurements. During 2020, the company recognized impairment charges of $31.4 million related to certain intangible assets and fixed assets. The combined fair values of the assets were estimated to be zero at December 31, 2020. The company also recognized net unrealized gains on certain investments of $0.9 million. The combined fair values of these investments were estimated to be $35.2 million. These assessments were based on quantitative and qualitative indications of impairment. The fair value measurements of the investments, fixed assets and assets held for sale are considered level 3 and non-recurring.

Fair Values of Debt Notes. The following presents the estimated fair values of long-term debt notes, which are carried at amortized cost on the consolidated balance sheets. The fair values below that are classified as level 2 under the fair value hierarchy were estimated using quoted market prices in inactive markets.

82

At December 31, 2020, the fair values (in U.S. dollar equivalents) were as follows:

(in millions)	Fair Value	Level
$750.0 million fixed rate notes due September 2022	785.1	Level 2
€15.0 million fixed rate notes due May 2023	20.3	Level 2
$750.0 million fixed rate notes due March 2025	822.4	Level 2
$500.0 million fixed rate notes due June 2028	594.4	Level 2
$750.0 million fixed rates notes due September 2043	1,113.9	Level 2
$700.0 million fixed rate notes due June 2048	941.6	Level 2

19. EARNINGS PER SHARE

Basic earnings per share is computed by dividing net income by the weighted average number of shares of all classes of 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 awards were as follows for the years presented:

(in thousands)	2020	2019	2018

There were no changes in the company’s internal control over financial reporting which occurred during 2020, that have materially affected, or are reasonably likely to materially affect, the company’s internal control over financial reporting.

Management’s Annual Report on Internal Control over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting. Our internal control system has been designed to provide reasonable assurance to management and the board of directors regarding the preparation and fair presentation of published financial statements.

Management assessed the effectiveness of the company’s internal control over financial reporting as of December 31, 2020. Management based its assessment on criteria for effective internal control over financial reporting described in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework). Management’s assessment included evaluating the design of our internal control over financial reporting and testing the operational effectiveness of our internal control over financial reporting. The results of its assessment were reviewed with the audit committee of the board of directors.

Based on this assessment, management believes that, as of December 31, 2020, our internal control over financial reporting is effective. The effectiveness of our internal control over financial reporting as of December 31, 2020 has been audited by Ernst & Young LLP, an independent registered public accounting firm, as stated in the report on page 88.

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Directors of CME Group Inc. and Subsidiaries

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of CME Group Inc. and subsidiaries (the Company) as of December 31, 2020 and 2019, the related consolidated statements of income, comprehensive income, equity, and cash flows for each of the three years in the period ended December 31, 2020, and the related notes and financial statement schedule listed in the Index at Item 15(a) (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2020 and 2019, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2020, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2020, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) and our report dated February 26, 2021 expressed an unqualified opinion thereon.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of the critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the account or disclosure to which it relates.

86

	Uncertain Tax Positions
Description of the Matter	As discussed in Note 10 to the consolidated financial statements, the Company had unrecognized income tax benefits of $328.2 million related to uncertain tax positions as of December 31, 2020. Uncertainty in a tax position may arise due to the application of complex tax regulations. The Company uses significant judgment to (1) determine whether, based on the technical merits, the tax position is more likely than not to be sustained upon examination and (2) measure the amount of the tax benefit that qualifies for recognition. Auditing management’s estimate of the Company’s uncertain tax positions that qualified for recognition and the related unrecognized income tax benefits was especially challenging because management’s estimate involved significant judgment in evaluating the technical merits of the positions, including interpretations of applicable tax laws and regulations.
How we Addressed the Matter in Our Audit	We tested the Company’s controls that address the risk of material misstatement relating to the recognition and measurement of uncertain tax positions. For example, we tested controls over the Company’s assessment of the technical merits of tax positions and management’s process to measure the benefit of those tax positions that qualified for recognition, including management’s review of the inputs used in the calculations. We involved our tax professionals to evaluate the technical merits of the Company's tax positions. Our audit procedures included, among others, evaluating the assumptions the Company used to develop its uncertain tax positions and related unrecognized income tax benefit amount by jurisdiction. We also tested the completeness and accuracy of the underlying data used by the Company to calculate its uncertain tax positions, inspected correspondence with relevant tax authorities, and evaluated third-party advice obtained and used by the Company in assessing the technical merits of its tax positions.

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Directors of CME Group Inc. and Subsidiaries

Opinion on Internal Control over Financial Reporting

We have audited CME Group Inc. and subsidiaries’ internal control over financial reporting as of December 31, 2020, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, CME Group Inc. and subsidiaries (the Company) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2020, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of CME Group Inc. and subsidiaries as of December 31, 2020 and 2019, the related consolidated statements of income, comprehensive income, equity and cash flows for each of the three years in the period ended December 31, 2020, and the related notes and financial statement schedule listed in the Index at Item 15(a) and our report dated February 26, 2021 expressed an unqualified opinion thereon.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Annual Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
