restricted stock units financial

"shares acquired on vesting and settlement of restricted stock units"

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.

withholding tax financial

"withheld by the issuer to pay the applicable withholding tax"

Withholding tax is a government-required portion of a payment—such as dividends, interest, or salary—that the payer keeps back and sends directly to tax authorities before the recipient receives the money. For investors it reduces the cash they actually get and changes the after-tax return on an investment; rates and refund or credit rules vary by country and can materially affect comparisons between similar investments, like a cashier holding part of a bill to cover taxes.

contingent right financial

"Each restricted stock unit represents a contingent right to receive one share"
