Restricted Stock Units financial

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

contingent right financial

"Each Restricted Stock Unit ("RSU") represents a contingent right to receive either one share"

fair market value financial

"or an amount of cash equal to the fair market value of one share of Common Stock"

The price a willing buyer and a willing seller would agree on for an asset or security when neither is under pressure and both have access to the same information. Think of it as the market’s neutral estimate of what something is worth, like the price two neighbors would settle on for a car after comparing similar listings. Investors care because fair market value guides buying and selling decisions, tax reporting, portfolio valuation, and how accurately company assets are reflected in financial statements.
