Restricted Stock Unit financial
"security_title: "Restricted Stock Unit" and footnote describing contingent right"
A restricted stock unit is a promise from a company to give an employee shares of stock after certain conditions are met, like staying with the company for a set amount of time. It’s like earning a bonus that turns into company stock once you’ve proven your commitment, making it a way to motivate and reward employees.
