Respect for Human Rights
CME Group is committed to treating all of its colleagues with respect, dignity and ensuring
safe working conditions. In support of this commitment, CME Group has adopted businessprinciples, corporate values and ethical standards and through this Statement represents its
commitment to challenge and confront the use of forced, compulsory, trafficked or child laborwithin its own organization and its supply chains.
Risk Assessment
As a financial services and technology company, CME Group believes that it operates within
an industry with a low risk of supporting or encountering slavery or human trafficking, basedon the nature of the relevant products and services as well as the locations of its significant
operations (predominantly in the United States and the United Kingdom where suchactivities are prohibited). Additionally, CME Group’s supply chains are limited. Generally, weprocure computer equipment as well as office supplies, equipment and services for the daily
running of our businesses. In addition, from time to time, we use third party vendors andcontractors for technology support and development, and for various advisory services. CME
Group does not manufacture or sell any physical goods and, therefore, we have no supply
chain relating to such activities.

1Anti-Slavery Policy and Practices
Notwithstanding our low risk for supporting slavery or human trafficking, we are committed toessential ethical standards and mandates compliance with the laws and regulations in thejurisdictions where we operate and respect the human rights of others.
We have an established global corporate compliance and ethics program (the “Program”),
which is designed to promote integrity and ethical business practices throughout ourorganization under the leadership of our MD Chief Enterprise Risk Management andCompliance Officer. The Program is overseen at the CME Group Board level by our Risk
Committee.
Our policies reflect our commitment to acting ethically and with integrity in all our business
relationships and to implementing and enforcing effective systems and controls designed toensure slavery or human trafficking is not taking place anywhere in our business or supply

Third Party Suppliers
We have an established dedicated Third Party Risk Management (“TPRM”) Program.

processes to identify any heightened risks of slavery or human trafficking. As part of TPRM’sdue diligence activities, TPRM conducts an Office of Foreign Assets Control (“OFAC”)
screen for all material third parties. The OFAC screen aims to identify and prevent anycontracts being executed with countries, companies, or organizations which are undersanctions by the United States government. We also have in place policies and procedures
and legal agreements that require third parties to comply with applicable laws and thestandards of CME Group. Suppliers that are rated as higher risk in relation to potential
human rights violations are subject to additional due diligence.
Reporting of Violations of the Slavery or Human Trafficking
Pursuant to the Code of Conduct, colleagues are obligated to report immediately any
business conduct or other conduct of which they become aware that might raise a legal or
ethical issue (including human rights issues, such as slavery and human trafficking) and any
instance where it is observed that anyone is being treated in a manner inconsistent with our
non-discrimination policies. To encourage reporting, we offer multiple reporting options(including an anonymous helpline) for employees and other third parties to make conﬁdential
reports, raise complaints and request guidance about compliance or ethical issues, including
matters referred to in our policies. We promote these reporting options through our internal
policies, communications and trainings. These reporting options provide an avenue throughwhich we can ensure that any potential slavery, human trafficking or wider human rights
impacts are identified and dealt with appropriately in our organization. Each report of suspected
misconduct is investigated by appropriate groups within our organization and, where a violationof policy is substantiated, corrective action is taken. We also have a policy prohibiting retaliation
for raising concerns based on the reasonable belief that misconduct has occurred.
Our Continuing Commitment
We will continue to engage with our people and vendors to raise awareness and to take further
steps to ensure that slavery and human trafficking are not taking place within our business andsupply chain.
