restricted stock financial

"Represents a grant of restricted stock under the CME Group Omnibus Stock Plan"

Shares granted to an individual that carry limits on transfer or sale until certain conditions are met, such as staying with the company for a set time or hitting performance targets. Think of them as a locked gift that gradually opens; for investors they matter because they affect how many shares may enter the market later, signal management incentives and potential dilution, and reveal confidence in future company performance.

revocable living trust financial

"from direct to indirect ownership via transfer to the Reporting Person's revocable living trust"

Rule 16a-13 regulatory

"exempt from Section 16 pursuant to Rule 16a-13 under the Securities Exchange Act"

tax withholding obligations financial

"shares surrendered to the Issuer to satisfy tax withholding obligations in connection"

beneficial ownership financial

"Reflects a change in the form of beneficial ownership from direct to indirect ownership"

Beneficial ownership means the person or entity that actually enjoys the benefits of owning shares or other assets — such as receiving dividends, voting rights, or price gains — even if the legal title is held in another name. For investors it matters because knowing who truly controls and profits from a company reveals who can influence decisions, exposes potential conflicts of interest or hidden concentration of power, and affects transparency and risk in the stock.
