Class C Common Stock financial

"The security title reported is Class C Common Stock"

A class C common stock is a type of company share that usually represents ownership but often carries limited or no voting power compared with other share classes. For investors, that matters because it can affect influence over company decisions and sometimes the stock’s price or dividend priority — think of it as owning a ticket to the same event but in a section with less say in how the event is run.

beneficially owned financial

"No Class A Common Stock (UAA) is beneficially owned"

Beneficially owned describes securities or assets where a person has the economic rights and control—such as the right to receive dividends and to direct voting—even if legal title is held in another name. Think of it like having the keys and using a car that’s registered to someone else: you get the benefits and make decisions. Investors care because beneficial ownership reveals who truly controls value and voting power, affecting corporate decisions and takeover dynamics.

transaction code F financial

"Transaction code F indicates payment of exercise price or tax liability"

exercise price or tax liability financial

"Payment of exercise price or tax liability by delivering or withholding securities"
