"equity compensation program for non-employee directors under the CME Group Director Stock Plan"

Non-employee directors are board members who do not work for the company as salaried employees and usually do not hold day-to-day management roles. They act like outside referees or independent coaches, providing oversight, asking tough questions, and protecting shareholders’ interests; investors care because these directors help ensure management is accountable, reduce conflicts of interest, and influence decisions that affect company strategy and long-term value.
