Clearing and transaction fees are assessed upfront at the time of trade execution. As </span></div><div style="line-height:120%;padding-bottom:6px;padding-top:6px;text-align:left;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">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. </span></div><div style="line-height:120%;padding-bottom:6px;padding-top:6px;text-align:left;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">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. </span></div><div style="line-height:120%;padding-bottom:6px;padding-top:6px;text-align:left;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;">Market data and information services.</span><span style="font-family:inherit;font-size:10pt;"> 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. </span></div><div style="line-height:120%;padding-bottom:6px;padding-top:6px;text-align:left;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;">Other. </span><span style="font-family:inherit;font-size:10pt;">Other revenues include access and communication fees, fees for collateral management, fees for trade order routing through agreements from various strategic relationships, as well as other post-trade services to customers and clearing firms. 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 CME 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. 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. </span></div><div

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 reported on the consolidated balance sheets on a contract-by-contract basis at the end of each reporting period. For annual licenses and upfront fee arrangements, the company generally bills customers upon contract execution. These 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, 2019 were not materially impacted by any other factors. The balance of contract liabilities was </span><span style="font-family:inherit;font-size:10pt;"><span>$57.9 million</span></span><span style="font-family:inherit;font-size:10pt;"> and </span><span style="font-family:inherit;font-size:10pt;"><span>$44.4 million</span></span><span style="font-family:inherit;font-size:10pt;"> as of </span><span style="font-family:inherit;font-size:10pt;">June 30, 2019</span><span style="font-family:inherit;font-size:10pt;"> and </span><span style="font-family:inherit;font-size:10pt;">December 31, 2018</span>, respectively.

NYMEX’s motion to dismiss was denied in 2014. Based on its investigation to date and advice from legal counsel, the company believes that it has strong factual and legal defenses to the claim. </span></div><div style="line-height:120%;padding-bottom:6px;padding-top:6px;text-align:left;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">In 2003, the U.S. Futures Exchange, L.L.C. (Eurex U.S.) and U.S. Exchange Holdings, Inc. filed suit in federal court alleging that CBOT and CME violated the antitrust laws and tortuously interfered with the business relationship and contract between Eurex U.S. and The Clearing Corporation. On October 31, 2018, the Court granted CBOT's and CME's motion for summary judgment and dismissed the case in its entirety. Eurex has appealed this decision. </span></div><div style="line-height:120%;padding-bottom:6px;padding-top:6px;text-align:left;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">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. </span></div><div style="line-height:120%;padding-bottom:6px;padding-top:6px;text-align:left;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">In addition, the company is a defendant in, and has potential for, various other legal proceedings arising from its regular business activities.
