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;

•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;

•our ability to accommodate increases in contract volume and order transaction traffic and to implement enhancements without failure or degradation of the performance of our trading and clearing systems;
•our ability to execute our growth strategy and maintain our growth effectively;
•our ability to manage the risks, control the costs and achieve the synergies associated with our strategy for acquisitions, investments and alliances, including those associated with the performance of our joint ventures with S&P Dow Jones (S&P Dow Jones Indices LLC) in index services and in trade processing/post trade services (OSTTRA), our primary business and distribution partners’ actions and our partnership with Google Cloud;

•the unfavorable resolution of material legal proceedings.
For a detailed discussion of these and other factors that might affect our performance, see Item 1A. of our Annual Report on Form 10-K for the year ended December 31, 2023, filed with the Securities and Exchange Commission on February 28, 2024 and Item 1A. in Part II of this Quarterly Report on Form 10-Q.

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS
1. Basis of Presentation
The consolidated financial statements consist of CME Group Inc. (CME Group) and its subsidiaries (collectively, the company), including Chicago Mercantile Exchange Inc. (CME), Board of Trade of the City of Chicago, Inc. (CBOT), New York Mercantile Exchange, Inc. (NYMEX), Commodity Exchange, Inc. (COMEX) and NEX Group Limited (NEX). The clearing house is operated by CME.
The accompanying interim consolidated financial statements have been prepared by CME Group without audit. Certain notes and other information normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States have been condensed or omitted. In the opinion of management, the accompanying consolidated financial statements include all adjustments (consisting only of normal recurring adjustments) considered necessary to present fairly the financial position of the company at June 30, 2024 and December 31, 2023 and the results of operations and cash flows for the periods indicated. Quarterly results are not necessarily indicative of results for any subsequent period.
The accompanying consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto in CME Group’s Annual Report on Form 10-K for the year ended December 31, 2023, filed with the Securities and Exchange Commission (SEC) on February 28, 2024.
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, 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 non-cash collateral management, equity membership subscription fees, and fees for trade order routing through agreements from various strategic relationships. Access and communication fees are charged 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 non-cash 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 non-cash 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.

Interest rate swap |  | 23.3 |  |  | 23.1 |  |  | 45.4 |  |  | 42.7 |
Total clearing and transaction fees |  | 1,249.9 |  |  | 1,118.3 |  |  | 2,458.8 |  |  | 2,318.5 |
Market data and information services |  | 175.0 |  |  | 163.1 |  |  | 350.4 |  |  | 328.9 |
Other |  | 107.6 |  |  | 78.8 |  |  | 211.2 |  |  | 154.4 |
Total revenues |  | $ | 1,532.5 |  |  | $ | 1,360.2 |  |  | $ | 3,020.4 |  |  | $ | 2,801.8 |
Timing of Revenue Recognition |  |  |  |  |  |  |  |
Services transferred at a point in time |  | $ | 1,223.6 |  |  | $ | 1,093.1 |  |  | $ | 2,407.5 |  |  | $ | 2,270.6 |
Services transferred over time |  | 303.2 |  |  | 262.5 |  |  | 602.7 |  |  | 522.0 |
One-time charges and miscellaneous revenues |  | 5.7 |  |  | 4.6 |  |  | 10.2 |  |  | 9.2 |
Total revenues |  | $ | 1,532.5 |  |  | $ | 1,360.2 |  |  | $ | 3,020.4 |  |  | $ | 2,801.8 |

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 second quarter of June 30, 2024 were not materially impacted by any other factors. The balance of contract liabilities was $43.2 million and $13.2 million as of June 30, 2024 and December 31, 2023, respectively.
3. Performance Bonds and Guaranty Fund Contributions
Performance Bonds and Guaranty Fund Contribution Reinvestment. CME reinvests cash performance bonds and guaranty fund contributions and distributes a portion of the interest earned back to the clearing firms. The reinvestment of cash can include certain commercial and central bank deposits, government securities, reverse repurchase agreements, and money market funds. 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, 2024, CME maintained $76.3 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. Cash performance bonds and guaranty fund contributions are included as restricted cash and cash equivalents on the consolidated statements of cash flows.
In the second quarter and first six months of 2024, earnings from cash performance bond and guaranty fund contributions were $1,007.6 million and $2,044.3 million, compared with $1,540.1 million and $2,796.4 million in the second quarter and first six months of 2023, respectively. In the second quarter and first six months of 2024, expenses related to the distribution of interest earned on collateral reinvestments were $939.4 million and $1,906.9 million, compared with $1,432.8 million and $2,596.3 million in the second quarter and first six months of 2023, respectively. The earnings from cash performance bonds and guaranty fund contributions are included in investment income and the expense related to the distribution of interest earned is included in other non-operating income (expense) on the consolidated statements of income.
Clearing House Contract Settlement. The clearing house marks-to-market open positions at least onc e a day (twice a day for all futures and options contracts). Based on values derived from the mark-to-market 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 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.
During the first six months of 2024, the clearing house transferred an average of approximately $5.4 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, 2024 and December 31, 2023. 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.

6. 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 the company's 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.
A putative class action complaint was filed January 15, 2014 in the Circuit Court of Cook County, Chancery Division, against CME Group Inc. and the Board of Trade of the City of Chicago, Inc. The plaintiffs, certain Class B shareholders of CME Group and Class B members of CBOT, allege breach of contract and breach of the implied covenant of good faith and fair dealing for violations of their core rights granted in the defendants’ respective Certificates of Incorporation. On December 2, 2021, the court granted the plaintiffs’ motion for certification of a damages-only class. No trial date has been set. Given the uncertainty of factors that may potentially affect the resolution of the matter, at this time the company is unable to estimate the reasonably possible loss or range of reasonably possible losses in the unlikely event it were found to be liable at trial. Based on its investigation to date, the company believes that it has strong factual and legal defenses to the claims.
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 June 30, 2024 and December 31, 2023.

Intellectual Property Indemnifications. Certain agreements with customers and other third parties related to accessing the CME Group platforms, utilizing market data services and licensing SPAN and SPAN 2 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.
7. Leases
The company has operating leases for corporate offices. The operating leases have remaining lease terms of up to 14 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 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.

8. Guarantees
Mutual Offset Agreement. CME and Singapore Exchange Limited (SGX) maintain a mutual offset agreement with a current term through April 2025. 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 two-year period after April 2025 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, 2024, CME was contingently liable to SGX on letters of credit totaling $285.0 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 June 30, 2024 and December 31, 2023.
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, 2024 and December 31, 2023.

10. 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.
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 long-term debt notes. 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 investments that were adjusted to fair value.

Non-Recurring Fair Value Measurements. The company recognized an unrealized gain on investments of $1.5 million on an equity investment without readily determinable fair value. The fair value of this investment was estimated to be $8.6 million at June 30, 2024. This fair value assessment was based on quantitative factors, including observable price changes. The fair value measurement of this investment is considered level 3 and non-recurring.
Fair Values of Debt Notes. The follo wing presents the estimated fair values of short-term and 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.
At June 30, 2024, the fair values were as follows:

(in millions) | Fair Value |  | Level

11. Earnings Per Share
The company uses the two-class method to calculate basic and diluted earnings per common share because its Series G preferred stock are participating securities. Under the two-class method, undistributed earnings are allocated to common stock and participating securities according to their respective rights in undistributed earnings, as if all of the earnings for the period had been distributed. Basic earnings per common share is computed by dividing the net income attributable to common shareholders by the weighted average number of common shares outstanding during the period. Net income attributable to common shareholders is reduced for preferred stock dividends earned during the period. Preferred stock also receives a proportionate allocation of undistributed or overdistributed earnings for the period because Series G preferred stock has a contractual obligation to share in profits and losses of the company. Diluted earnings per share is computed by dividing the net income attributable to common shareholders by the weighted average number of common shares outstanding plus potentially dilutive common shares. Anti-dilutive stock awards were as follows for the periods presented:

| Quarter Ended June 30, |  | Six Months Ended June 30,

Clearing and Transaction Fees
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.

|  | Quarter Ended June 30, |  |  |  | Six Months Ended June 30, |  |

Table of Contents
We estimate the following net changes in clearing and transaction fees based on the changes in total contract volumes and the changes in average rate per contract for futures and options during the second quarter and first six months of 2024 when compared with the same periods in 2023.

(in millions) |  | Quarter Ended |  | Six Months Ended
Increases due to a changes in total contract volume |  | $ | 153.7 |  |  | $ | 111.6 |
Increase (decrease) due to a changes in average rate per contract |  | (22.8) |  |  | 31.5 |
Net increases in clearing and transaction fees |  | $ | 130.9 |  |  | $ | 143.1 |

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 conditions, the regulatory environment and market competition.

Market uncertainty remained high through the first six months of 2024. Interest rate, foreign exchange, and equity markets experienced significant uncertainty surrounding the United States Federal Reserve’s (Federal Reserve) interest rate policy decision. The Federal Open Markets Committee (FOMC) had initially signaled the potential for several future rate cuts throughout 2024, but has since indicated fewer cuts as a result of continued inflation. Energy, metals, and agricultural commodities markets were more uncertain in the first half of 2024 mainly as a result of geopolitical events as well as uncertain weather conditions, which led to higher volumes within those markets. We believe these factors contributed to total volumes increasing in the second quarter and first six months of 2024 when compared with the same periods in 2023.

In the second quarter and first six months of 2024, overall interest rate contract volumes increased when compared with the same periods in 2023. U.S. Treasury volumes increased in the second quarter and first six months of 2024 due to a shift in market expectations regarding the Federal Reserve's interest rate policy following the FOMC's indication of fewer rate cuts in the near future than previously anticipated and high levels of Treasury issuance.
Equity Index Products
The following table summarizes average daily contract volume for our key equity index products.

|  | Quarter Ended June 30, |  |  |  | Six Months Ended June 30, |  |

E-mini Russell 2000 futures and options |  | 282 |  |  | 311 |  |  | (9) |  |  | 309 |  |  | 321 |  |  | (4) |

In the second quarter and first six months of 2024, equity index contract volumes increased when compared with the same periods in 2023, which we believe were due to higher overall volatility within the Nasdaq 100. The second quarter and first six months of 2024 saw higher volatility within the technology sector while the broader market saw significantly lower volatility as indices have reached new all time highs. We believe these factors led to higher overall equity contract volumes in the second quarter and first six months of 2024.
Foreign Exchange Products
The following table summarizes average daily contract volume for our key foreign exchange products.

|  | Quarter Ended June 30, |  |  |  | Six Months Ended June 30, |  |
(amounts in thousands) |  | 2024 |  | 2023 |  | Change |  | 2024 |  | 2023 |  | Change

Australian dollar |  | 122 |  |  | 96 |  |  | 27 |  |  | 116 |  |  | 100 |  |  | 16 |

In the second quarter and first six months of 2024, overall foreign exchange volumes increased when compared with the same periods in 2023, which we believe were due to higher overall market volatility. Continued uncertainty surrounding monetary policy expectations from the Federal Reserve and global central banks resulted in higher volumes compared with the same periods in 2023.

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

|  | Quarter Ended June 30, |  |  |  | Six Months Ended June 30, |  |

Wheat |  | 293 |  |  | 244 |  |  | 20 |  |  | 254 |  |  | 215 |  |  | 18 |

Overall commodity contract volumes increased in the second quarter and first six months of 2024 when compared with the same periods in 2023. We believe these increases are due to higher overall market volatility as a result of a change in market expectations regarding grain supplies as well as weather conditions for 2024. In addition, the first half of 2023 saw lower overall volatility within the commodities markets due to risk aversion by market participants following price increases and global trade uncertainty resulting from the conflict between Russia and Ukraine. We believe these factors contributed to higher overall commodity volumes in the second quarter and first six months of 2024.
Energy Products
The following table summarizes average daily contract volume for our key energy products.

|  | Quarter Ended June 30, |  |  |  | Six Months Ended June 30, |  |
(amounts in thousands) |  | 2024 |  | 2023 |  | Change |  | 2024 |  | 2023 |  | Change

Refined products |  | 385 |  |  | 339 |  |  | 13 |  |  | 380 |  |  | 333 |  |  | 14 |

Energy contract volumes increased in the second quarter and first six months of 2024 when compared with the same periods in 2023, which we believe were due to higher overall market volatility. Natural gas volatility was higher as a result of uncertain weather conditions in the U.S., which impacted prices throughout the quarter. In addition, crude oil volatility was slightly higher as a result of ongoing geopolitical issues in the Middle East as well economic uncertainty between the U.S. and China.
Metal Products
The following table summarizes average daily volume for our key metal products.

|  | Quarter Ended June 30, |  |  |  | Six Months Ended June 30, |  |
(amounts in thousands) |  | 2024 |  | 2023 |  | Change |  | 2024 |  | 2023 |  | Change
Gold |  | 465 |  |  | 366 |  |  | 27 | % |  | 430 |  |  | 382 |  |  | 13 | %
Copper |  | 186 |  |  | 116 |  |  | 61 |  |  | 162 |  |  | 120 |  |  | 35 |
Silver |  | 165 |  |  | 98 |  |  | 69 |  |  | 130 |  |  | 96 |  |  | 36 |

In the second quarter and first six months of 2024, overall metal contract volumes increased when compared with the same periods in 2023, which we believe was due to higher market volatility. Copper volumes increased as a result of shortages in supply. In addition, continued uncertainty surrounding the Federal Reserves interest rate policy decision led to higher volumes within our gold and silver asset classes. We believe this market volatility led to the overall increases in metal contract volumes in the second quarter and first six months of 2024.
Average Rate per Contract
The average rate per contract decreased in the second quarter of 2024, when compared with the same period in 2023. The decrease in the average rate per contract was primarily due to higher member volume as a percentage of total volume.
The average rate per contract increased in the first six months of 2024, when compared with the same periods in 2023. The increase is largely due to a change in product mix. In the first quarter of 2024, equity index and interest rate contract volumes decreased by 2 percentage points as a percent of total volume, while all other products collectively increased by 2 percentage points. In general, equity index and interest rate products have a lower rate per contract compared with the remaining contracts. The increase in the average rate per contract was also due to an increase in our fee structure that went into effect on February 1, 2024.

Cash Markets Business
Total clearing and transaction fees revenues in the second quarter and first six months of 2024 include $70.4 million and $139.4 million of transaction fees attributable to the cash markets business, compared with $69.9 million and $144.9 million, respectively, in the second quarter and first six months of 2023. This revenue includes BrokerTec Americas LLC's fixed income volume and EBS's foreign exchange volume.

Spot FX |  | 57.4 |  |  | 54.8 |  |  | 5 | % |  | 54.7 |  |  | 59.6 |  |  | (8) |

Overall average daily notional values for the cash markets business were lower in the second quarter and first six months of 2024 when compared with the same periods in 2023.
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 at least approximately 10% of o ur clearing and transaction fees in the first six months of 2024. 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
Market data and information services. During the second quarter and first six months of 2024, overall market data and information services revenues increased when compared with the same periods in 2023, largely due to price increases for certain products.
The two largest resellers of our market data represented approximately 31% of our market data and information services revenue in the first six months of 2024. 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. In the second quarter and first six months of 2024, the increases in other revenues when compared with the same periods in 2023 were largely attributable to higher custody fees due to an increase in non-cash collateral as well as a fee increase. Other revenues also increased due to higher co-location and other connectivity fees.

Increases in operating expenses in the second quarter and first six months of 2024 when compared with the same periods in 2023 were as follows:
•The increases in expenses related to technology support services were primarily driven by higher software license fees and third party services to support the ongoing Google Cloud transformation project.
•License fees were higher primarily due to increases in volume for certain equity products.
•Salaries, benefits and employer taxes were higher due to increases in headcount during the year, which were primarily attributable to additional headcount in the company's international locations.
Decreases in operating expenses in the second quarter and first six months of 2024 when compared with the same periods in 2023 were as follows:
•Occupancy and building operations expenses decreased due to lower rent expenses and real estate taxes.
•Depreciation and amortization expense decreased as a result of certain assets becoming fully depreciated.
•The decreases in professional fees and outside services are largely due to decreases in consulting costs associated with the Google Cloud Migration, which began in late 2021, as well as lower professional services during the periods.

Investment income. Earnings from cash performance bond and guaranty fund contributions that are reinvested decreased in the second quarter of 2024 when compared with the same period in 2023, due to lower average reinvestment balances despite higher average rates of return. In the second quarter and first six months of 2024, earnings from cash performance bond and guaranty fund contributions were $1,007.6 million and $2,044.3 million, co mpared with $1,540.1 million and $2,796.4 million, respectively, in the second quarter and first six months of 2023. We also recognized lower net realized and unrealized gains on investments in the first six months of 2024.
Equity in net earnings (losses) of unconsolidated subsidiaries. Higher income generated from our S&P/Dow Jones Indices LLC (S&P/DJI) business venture contributed to an increase in equity in net earnings of unconsolidated subsidiaries in the second quarter and first six months of quarter of 2024 when compared with the same periods in 2023.
Other income (expense). We recognized lower expenses related to the distribution of interest earned on performance bond collateral reinvestments to the clearing firms in conjunction with lower interest income earned on our reinvestment during the second quarter and first six months of 2024 when compared with the same periods in 2023. In the second quarter and first six months of 2024, expenses related to the distribution of interest earned on collateral reinvestments we re $939.4 million and $1,906.9 million, compared with $1,432.8 million and $2,596.3 million in the second quarter and first six months of 2023.
Income Tax Provision
The following table summarizes the effective tax rates for the periods presented:

|  | 2024 |  | 2023
Quarter ended June 30 |  | 23.5 | % |  | 23.5 | %
Six months ended June 30 |  | 23.3 |  |  | 23.6 |

The overall effective tax rate remained relatively consistent in the second quarter and first six months of 2024 when compared with the same periods in 2023.
Liquidity and Capital Resources
Sources and Uses of Cash. Net cash provided by operating activities increased in the first six months of 2024 when compared with the same period in 2023 was largely due to an increase in revenues. Cash used in investing activities increased in the first six months of 2024 when compared with the same period in 2023 due to a decrease in proceeds from sales of investments. Cash used in financing activities was lower during the first six months of 2024 when compared with the same period in 2023 due to a smaller decrease in cash performance bonds and guaranty fund contributions.

Debt Instruments. The following table summarizes our debt outstanding at June 30, 2024:

(in millions) | Par Value
Fixed rate notes due March 2025, stated rate of 3.00% (1) | $ | 750.0 |
Fixed rate notes due June 2028, stated rate of 3.75% | 500.0 |

_______________
(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 3.11%.
(2)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 $2.3 billion multi-currency revolving senior credit facility with various financial institutions, which matures in November 2026. 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 $3.3 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, 2021, 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, 2024, guaranty fund contributions available to collateralize the facility totaled $9.8 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's 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 $2.3 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, 2024, we have excess borrowing capacity for general corporate purposes of approximately $2.3 billion under our multi-currency revolving senior credit facility.
At June 30, 2024, 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 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, 2024, the letters of credit totaled $285.0 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, 2024:

|  | 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 within certain specified time periods 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. No report of any rating agency is incorporated by reference herein.
Liquidity and Cash Management. Cash and cash equivalents totaled $1.8 billion and $2.9 billion at June 30, 2024 and December 31, 2023, 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 cash performance bonds and guaranty fund contributions, other current assets or other assets in the consolidated balance sheets.
Regulatory Requirements. CME is regulated by the CFTC as a 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.
