Commitments and Contingencies Disclosure [Abstract] |
Contingencies | 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. In early 2024, the defendants moved for summary judgment on all claims. The court heard oral argument on that motion on January 31, 2025. Should the case proceed past summary judgment in whole or in part, the Court has set the matter for a jury trial starting on July 7, 2025. Plaintiffs have produced an expert report estimating damages through June 30, 2023, and claiming that additional damages in an unspecified amount continue to accrue on a daily basis through final judgment. The defendants believe that the damages report is invalid under Illinois law and on that basis have filed a motion to exclude the expert from offering an opinion at trial and a motion to decertify the class. 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 December 31, 2024 and 2023. Intellect ual 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 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.
