Forward-Looking Statements
From time to time, in this Quarterly Report on Form 10-Q as well as in other written reports and verbal statements, we discuss our expectations regarding future performance. These forward-looking statements are identified by their use of terms and phrases such as "believe," "anticipate," "could," "estimate," "intend," "may," "plan," "expect" and similar expressions, including references to assumptions. These forward-looking statements are based on currently available competitive, financial and economic data, current expectations, estimates, forecasts and projections about the industries in which we operate and management's beliefs and assumptions. These statements are not guarantees of future performance and involve risks, uncertainties and assumptions that are difficult to predict. Therefore, actual outcomes and results may differ materially from what is expressed or implied in any forward-looking statements. We want to caution you not to place undue reliance on any forward-looking statements. We undertake no obligation to publicly update any forward-looking statements, whether as a result of new information, future events or otherwise. Among the factors that might affect our performance are:
increasing competition by foreign and domestic entities, including increased competition from new entrants into our markets and consolidation of existing entities;
our ability to keep pace with rapid technological developments, including our ability to complete the development, implementation and maintenance of the enhanced functionality required by our customers while maintaining reliability and ensuring that such technology is not vulnerable to security risks;
our ability to continue introducing competitive new products and services on a timely, cost-effective basis, including through our electronic trading capabilities, and our ability to maintain the competitiveness of our existing products and services, including our ability to provide effective services to the swaps market;

the costs associated with protecting our intellectual property rights and our ability to operate our business without violating the intellectual property rights of others;
decreases in revenue from our market data as a result of decreased demand or changes to regulations in various jurisdictions;
changes in our rate per contract due to shifts in the mix of the products traded, the trading venue and the mix of customers (whether the customer receives member or non-member fees or participates in one of our various incentive programs) and the impact of our tiered pricing structure;

the ability of our credit and liquidity risk management practices to adequately protect us from the credit risks of clearing members and other counterparties, and to satisfy the margin and liquidity requirements associated with the BrokerTec matched principal business;
the ability of our compliance and risk management methods to effectively monitor and manage our risks, including our ability to prevent errors and misconduct and protect our infrastructure against security breaches and misappropriation of our intellectual property assets;
our dependence on third-party providers and exposure to risk through third parties, including risks related to the performance, reliability and security of technology used by our third-party providers;
volatility in commodity, equity and fixed income prices, and price volatility of financial benchmarks and instruments such as interest rates, credit spreads, equity indices, fixed income instruments and foreign exchange rates;
economic, social, political and market conditions, including the volatility of the capital and credit markets and the impact of economic conditions on the trading activity of our current and potential customers;

The accompanying consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto in CME Group’s Annual Report on Form 10-K for the year ended December 31, 2020, filed with the Securities and Exchange Commission (SEC) on February 26, 2021.
2. 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.
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. The company also has 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 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. These upfront customer payments are recognized as revenue over time as the obligations under the contracts are satisfied. Changes in the contract liability balances during the six months ended June 30, 2021 were not materially impacted by any other factors. The balance of contract liabilities was $36.6 million and $37.3 million as of June 30, 2021 and December 31, 2020, respectively. There is also $31.2 million of contract liabilities included in the liabilities held for sale balance at June 30, 2021 in connection with the net assets that will be contributed to a joint venture with IHS Markit.
3. Assets and Liabilities Held for Sale
On January 12, 2021, the company announced that it has agreed with IHS Markit to combine their post-trade services into a new joint venture. The new company will perform trade processing and risk mitigation services. The company will contribute its optimization business, which includes Traiana, TriOptima and Reset, to the new joint venture for an equity interest in the new company. The transaction is expected to close in the third quarter of 2021, subject to customary antitrust and regulatory approvals and other customary closing conditions.
In January 2021, the net assets that will be contributed to the joint venture were classified as held for sale following approval of the transaction by the company's Board of Directors. The reclassification of the assets and liabilities to held for sale did not have an impact on earnings with the exception of amortization expense. Amortization expense is no longer taken on intangible assets once reclassified to assets held for sale.
4. Performance Bonds and Guaranty Fund Contributions
Performance Bonds and Guaranty Fund Contributions. 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 June 30, 2021, CME maintained $130.5 billion within the cash account at the Federal Reserve Bank of Chicago. The cash deposit at the Federal Reserve Bank of Chicago is included within performance bonds and guaranty fund contributions on the consolidated balance sheets.
Clearing House Contract Settlement. The clearing house marks-to-market open positions for all futures and options contracts twice a day (once a day for CME's cleared-only interest rate swap contracts). Based on values derived from the mark-to-market
15

Table of Contents

process, the clearing house requires payments from clearing firms whose positions have lost value and makes payments to clearing firms whose positions have gained value. Under the extremely unlikely scenario of simultaneous default by every clearing firm who has open positions with unrealized losses, the maximum exposure related to positions other than cleared-only 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 CME's cleared-only interest rate swap contracts, the maximum exposure related to CME's guarantee would be one full day of changes in fair value of all open positions, before considering CME's ability to access defaulting clearing firms' collateral.
During the first six months of 2021, the clearing house transferred an average of approximately $4.1 billion a day through its clearing systems for settlement from clearing firms whose positions had lost value to clearing firms whose positions had gained value. The clearing house reduces its guarantee exposure through initial and maintenance performance bond requirements and mandatory guaranty fund contributions. 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 June 30, 2021. The company does not have a history of significant losses recognized on performance bond collateral as posted by our clearing members, and management currently does not anticipate any future credit losses on its performance bond assets. Accordingly, the company has not provided an allowance for credit losses on these performance bond deposits, nor has it recorded any liabilities to reflect an allowance for credit losses related to our off-balance sheet credit exposures and guarantees.
5. Intangible Assets and Goodwill
In January 2021, the net assets that will be contributed to a joint venture with IHS Markit were classified as held for sale. As a result, $1.1 billion of amortizable intangible assets were reclassified to assets held for sale on the consolidated balance sheet. Amortization expense is no longer taken on these intangible assets once reclassified to assets held for sale.
Intangible assets consisted of the following at June 30, 2021 and December 31, 2020:

7. 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 legal and regulatory matters as none were probable and estimable as of June 30, 2021 and December 31, 2020.
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.
8. Leases
The company has operating leases for 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 whether these options are exercisable 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 data center 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.

9. 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 their intent to terminate. CME can maintain collateral in the form of irrevocable, standby letters of credit. At June 30, 2021, CME was contingently liable to SGX on 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
20

Table of Contents
clearing house. Based on the assessment performed, management estimates the guarantee liability to be nominal and therefore has not recorded any liability at June 30, 2021.
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 commodity products and who suffer losses to their segregated account balances due to their CME clearing member becoming insolvent. Under the terms of the Fund, farmers and ranchers are eligible for up to $25,000 per participant. Farming and ranching cooperatives are eligible for up to $100,000 per cooperative. The Fund was established with a maximum of $100.0 million available for distribution to participants. Since its establishment, the Fund has made payments of approximately $2.0 million, which leaves $98.0 million available for future claims. If, at any time, payments due to participants were to exceed the amount remaining in the fund, payments would be pro-rated. Clearing members and customers must register with the company in advance and provide certain documentation in order to substantiate their eligibility. The company believes that its guarantee liability is nominal and therefore has not recorded any liability at June 30, 2021.

11. Fair Value Measurements
The company uses a three-level classification hierarchy of fair value measurements for disclosure purposes:
Level 1 inputs, which are considered the most reliable evidence of fair value, consist of quoted prices (unadjusted) for identical assets or liabilities in active markets.
Level 2 inputs consist of observable market data, such as quoted prices for similar assets and liabilities in active markets, or inputs other than quoted prices that are directly observable.
Level 3 inputs consist of unobservable inputs which are derived and cannot be corroborated by market data or other entity-specific inputs.
21

Table of Contents
The company's level 1 assets generally include investments in publicly traded mutual funds, equity 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.
The company's 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.
The company's level 3 assets and liabilities include certain fixed assets and investments that were adjusted to fair value.
Recurring Fair Value Measurements. Financial assets and liabilities recorded at fair value on the consolidated balance sheet as of June 30, 2021 were classified in their entirety based on the lowest level of input that was significant to each asset and liability's fair value measurement. The following table presents financial instruments measured at fair value on a recurring basis:

Non-Recurring Fair Value Measurements. The company recognized impairment charges of $0.5 million related to certain fixed assets in the first six months of 2021. The fair value of these fixed assets was estimated to be zero at June 30, 2021. The company also recognized net unrealized loss on investments of $0.2 million. The fair value of these investments was estimated to be $9.2 million at June 30, 2021. These assessments were based on quantitative and qualitative indicators of fair value. The fair value measurements of the fixed assets and investment are considered level 3 and non-recurring.
Fair Values of Long-Term 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 are classified as level 2 under the fair value hierarchy and were estimated using quoted market prices in inactive markets.

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

Futures and Options Contracts
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 exclude trading volume for the cash markets business and interest rate swaps volume.

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.

Overall market volatility increased throughout the second quarter of 2021 following periods of lower volatility, particularly in the second quarter of 2020. In the second quarter of 2021, the Federal Reserve indicated a potential increase in interest rates earlier than many market participants expected as a result of higher than anticipated inflation data, which resulted in higher volatility within the interest rate market. In addition, increased demand for corn and soybean resulted in higher market volatility within the agricultural commodity market. However, volatility within the equity and energy subsided in the second quarter of 2021 when compared to the same periods in 2020 within the equity and energy markets. We believe these factors led to the changes in contract volume during the second quarter and first six months of 2021, when compared with the same periods in 2020.
Following the Illinois stay at home orders in March 2020, we closed the trading floor in Chicago. We began a limited re-opening of the trading floor in the third quarter of 2020. Only the Eurodollar options trading pit (where options on One-Month and Three-Month Secured Overnight Financing Rate (SOFR) futures also trade) will remain open. We do not plan to reopen the remaining trading floor pits.

In the second quarter of 2021, overall interest rate contract volume increased when compared with the same period in 2020, which we believe resulted from increased interest rate volatility due to a change in market expectations. Interest rate volatility increased following the Federal Reserve's indication that it would raise interest rates sooner than expected as a result of higher than anticipated inflation data.

We believe overall interest rate contract volume decreased in the first six months of 2021 due to significant volatility in the first quarter of 2020 as a result of economic uncertainty caused by the governmental and business response to the COVID-19 pandemic.

In the second quarter and the first six months of 2021, equity index contract volumes decreased when compared with the same periods in 2020. Volatility within the broad-based indexes, including the S&P 500, subsided in the second quarter of 2021 following significant equity market volatility in early 2020 resulting from uncertainty surrounding the economic impact of governmental and business actions to combat the COVID-19 pandemic. However, there was an increase in volatility within certain narrow-based technology indexes, which resulted from a market repricing of certain stocks in early 2020. We believe this increase in volatility contributed to an increase in E-mini Nasdaq 100 contracts.

Overall foreign exchange contract volume increased in the second quarter of 2021 when compared with the same period in 2020. We believe this is mainly attributable to improvements in the global economic outlook as well as a decline in risk aversion by market participants following the COVID-19 pandemic.
Market volatility subsided in the first six months of 2021 when compared with the same period in 2020 following very high foreign exchange volatility in the first six months of 2020 caused by significant uncertainty surrounding the economic impacts of the governmental and business actions to combat the COVID-19 pandemic. We believe these factors led to the decrease in foreign exchange contract volume.

Overall commodity contract volumes increased in the second quarter and the first six months of 2021 when compared with the same periods in 2020. Corn and soybean contract volumes increased due to increased prices, which we believe were caused by expectations of lower than expected crop yields.

Overall energy contract volumes decreased in the second quarter and the first six months of 2021 when compared with the same periods in 2020, largely due to decreases in price volatility within the crude oil markets. The crude oil market exhibited less volatility as the market continued to rebalance from a reduction in demand caused by the COVID-19 pandemic. In addition, forecasts of warmer than expected weather resulted in decreases in natural gas contract volumes.

Copper119 84 41 119 102 16 
Silver100 80 25 114 102 11 
In the second quarter of 2021, metal contract volume increased when compared with the same period in 2020. We believe this volume increase is due to a shift by market participants into copper and silver contracts as gold contract volumes have been under pressure as a result of a high U.S. dollar and an increase in treasury yields.
The decrease in metal contract volume in the first six months of 2021 when compared to the same period in 2020 can be attributed to lower overall market volatility within the gold market. In early 2020, investors were using gold and other precious metals as safe-haven investments as a result of uncertainty within other markets caused by the governmental and business actions to combat the COVID-19 pandemic.
Average Rate per Contract
The average rate per contract decreased in the second quarter of 2021 when compared with the same period in 2020. The decrease was largely due to a shift in product mix. In the second quarter of 2021, interest contract volume increased by 7 percentage points as a percentage of total volume, while contract volume almost all other product lines collectively decreased as a percentage of total volume. Interest rate contracts have a lower average rate per contract compared with other product lines.

Table of Contents
In the first six months of 2021 when compared with the same period in 2020, the decrease in the average rate per contract was largely due to the increase in the micro-E-mini equity index contract volume, which have a lower average rate per contract compared with the standard E-mini contracts. Micro-E-mini equity index contracts have a notional size of one-tenth of the traditional E-mini contracts.
Cash Markets Business
Total clearing and transaction fees revenues in the second quarter and the first six months of 2021 include $105.7 million and $220.9 million of transaction fees attributable to the cash markets business compared with $112.4 million and $236.8 million in the second quarter and first six months of 2020, respectively. This revenue primarily includes BrokerTec Americas LLC's fixed income volume and EBS's foreign exchange volume.

Overall average daily notional value for the cash markets business increased in the second quarter 2021 compared with the same period in 2020. The increases in European Repo transactions are largely due to increases in volatility as a result of higher than expected inflation data.
Overall average daily notional value for the cash markets business decreased in the first six months of 2021 compared with the same period in 2020. The decrease in trading is largely due to lower volatility as the first quarter of 2020 saw high volatility as a result of the uncertainty surrounding the COVID-19 pandemic.
Concentration of Revenue
We bill a substantial portion of our clearing and transaction fees directly to our clearing firms. The majority of clearing and transaction fees received from clearing firms represent charges for trades executed and cleared on behalf of their customers. One individual firm represented approximately 10% of our clearing and transaction fees in the first six months of 2021. Should a clearing firm withdraw, we believe that the customer portion of the firm’s trading activity would likely transfer to another clearing firm of the exchange. Therefore, we do not believe we are exposed to significant risk from the ongoing loss of revenue received from or through a particular clearing firm.
Other Sources of Revenue
During the second quarter and first six months of 2021, overall market data and information services revenue increased when compared with the same periods in 2020 largely due to price increases for certain products.
The two largest resellers of our market data represented approximately 33% of our market data and information services revenue in the first six months of 2021. Despite this concentration, we consider exposure to significant risk of revenue loss to be minimal. In the event that one of these vendors no longer subscribes to our market data, we believe the majority of that vendor’s customers would likely subscribe to our market data through another reseller. Additionally, several of our largest institutional customers that utilize services from our two largest resellers report usage and remit payment of their fees directly to us.
In the first six months of 2021, the decrease in other revenue when compared with the same period in 2020 was largely due to a decrease in custody fees resulting from a decrease in the overall level of non-cash performance bonds and guaranty fund collateral.

Decreases in operating expenses in the second quarter and first six months of 2021 when compared with the same periods in 2020 were as follows:
Amortization of purchased intangibles was lower during the second quarter and first six months of 2021, as intangible assets related to CME Group's optimization business were classified as held for sale following approval of the IHS Markit joint venture by the company's Board of Directors. Amortization is no longer taken on intangible assets once they are classified as held for sale.
In the second quarter and first six months of 2020, we recognized higher impairment charges on certain intangibles and fixed assets related to a subsidiary.
Professional fees and outside services expenses decreased due to a greater reliance on technology consultants for platform integrations, information security and systems enhancements in 2020 as well as a reduction in legal fees related to our business activities and product offerings.
A decrease in licensing and other fee agreements expense was due to lower volumes for certain equity products in the second quarter and first six months of 2021 when compared to the same periods in 2020.
A decrease in our non-qualified deferred compensation liability during the second quarter of 2021 when compared with the same period in 2020, the impact of which does not affect net income because of an equal and offsetting change in investment income, contributed to a decrease in compensation and benefits expense.
Increases in operating expenses in the second quarter and first six months of 2021 when compared with the same periods in 2020 were as follows:
Employee separation and retention costs were higher during the second quarter and first six months of 2021 due to a higher reduction in workforce compared to the same periods in 2020.

Investment income.

Overall investment income decreased in first six months of 2021 when compared with the same period in 2020, largely due to a decrease in earnings from cash performance bond and guaranty fund contributions that are reinvested. The decrease in earnings resulted largely 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 by the Federal Reserve, despite an increase in reinvestment balances.
Equity in net earnings (losses) of unconsolidated subsidiaries. In the second quarter and first six months of 2021, when compared with the same periods in 2020, higher income generated from our S&P/Dow Jones Indices LLC (S&P/DJI) business venture contributed to increases in equity in net earnings (losses) of unconsolidated subsidiaries.
Other income (expense). Other expenses increased in the second quarter of 2021 when compared with the same period in 2020 largely due to an increase in the distribution of interest earned on performance bond collateral reinvestments to the clearing firms due to higher interest income earned on our reinvestment. Other expenses decreased in the first six months of 2021 when compared with the same period in 2020 due 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 during the six month period.

Liquidity and Capital Resources
Sources and Uses of Cash. Net cash provided by operating activities decreased in the first six months of 2021 when compared with the same period in 2020 largely due to the timing of income tax payments made, as well as a decrease in trading volume. Net cash used in investing activities was lower during the first six months of 2021 when compared with the same period in 2020 largely due to an increase in proceeds from sales of investments. Cash used in financing activities was lower during the first six months of 2021 when compared with the same period in 2020 due to net repayments of commercial paper made during the first six months of 2020.

(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 CME Group's discretion and, if necessary, for maturities of commercial paper. As long 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 any commercial paper balance if or when outstanding can be 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 the clearing house. 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 depositary (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 June 30, 2021, guaranty fund contributions available to collateralize the facility totaled $7.6 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 remain in compliance with a consolidated tangible net worth test, defined as CME consolidated shareholder's equity less intangible assets (as defined in the agreement), of not less than $800.0 million. 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 June 30, 2021, we have excess borrowing capacity for general corporate purposes of approximately $2.4 billion under our multi-currency revolving senior credit facility.
At June 30, 2021, we were in compliance with the various financial 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 the funds which it uses to pay dividends to its shareholders.
To satisfy our performance bond obligation with Singapore Exchange Limited, we may pledge irrevocable standby letters of credit. At June 30, 2021, the letters of credit totaled $310.0 million. We also maintain a $350.0 million line of credit to meet our obligations under this agreement.

The following table summarizes our credit ratings at June 30, 2021:  
   Short-Term  Long-Term   
Rating Agency  Debt Rating  Debt Rating  Outlook
Standard & Poor’s Global Ratings  A1+  AA-  Stable
Moody’s Investors Service, Inc.  P1  Aa3  Stable
Given our cash flow generation, our ability to pay down debt levels and our ability to refinance existing debt facilities if necessary, we expect to maintain an investment grade rating. If our ratings are downgraded below investment grade due to a change of control, we are required to make an offer to repurchase our fixed rate notes at a price equal to 101% of the principal amount, plus accrued and unpaid interest.
Liquidity and Cash Management. Cash and cash equivalents totaled $1.1 billion and $1.6 billion at June 30, 2021 and December 31, 2020, respectively. 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 in the consolidated balance sheets.
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 the Dodd-Frank Wall Street Reform and Consumer Protection Act. 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 the Financial Industry Regulatory Authority 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 Exchange Act Rule 15c3-3.
