Key Terms

3 terms

Restricted Stock Unit financial

"Each Restricted Stock Unit (RSU) represents a contingent right to receive one share of Issuer's common stock."

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.

RSU agreement financial

"RSUs vest 100% on the first anniversary of the date of grant, unless earlier vested or terminated pursuant to the terms of the RSU agreement."

derivative security financial

"transaction_code_description: Exercise or conversion of derivative security"

A derivative security is a financial contract whose value comes from the price or performance of something else, such as a stock, bond, commodity, or market index. For investors it acts like an insurance policy or a wager: it can be used to protect against losses, lock in prices, or amplify gains and losses, so it can change a portfolio’s risk and potential return without owning the underlying asset directly.
