Restricted Stock Units financial
"Each restricted stock unit represents a contingent right to receive one share of common stock"
Restricted stock units are a type of company reward where employees are promised shares of stock, but they only fully own these shares after meeting certain conditions, like staying with the company for a set time. They matter because they can become valuable assets and are often used to motivate employees to help the company succeed.
tax withholding obligations financial
"withholding of shares by the issuer to satisfy the Reporting Person's tax withholding obligations"
Continuous Service financial
"subject to the Continuous Service of the Reporting Person as of each such date"
derivative security financial
"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.
