Restricted Stock Unit financial

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

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.

contingent right financial

"represents a contingent right to receive either one share of the Issuer's common stock"

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.
