Restricted Stock Units financial
"Reflects shares of common stock delivered upon vesting and settlement of previously awarded restricted stock units ("RSUs")."
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.
RSUs financial
"Each RSU represents a contingent right to receive either one share of Common Stock or an amount of cash equal to the fair market value."
RSUs, or restricted stock units, are a form of company shares given to employees as part of their compensation. They are typically awarded with certain restrictions, such as a waiting period before they can be fully owned or sold, similar to earning a gift that becomes fully yours over time. For investors, RSUs can impact a company's stock offerings and reflect how much the company relies on stock-based incentives to attract and retain talent.
Common Stock financial
"Reflects shares of common stock of the Issuer ("Common Stock") delivered upon vesting and settlement of previously awarded restricted stock units."

It is the most common type of stock traded on markets and can provide income through dividends, as well as potential for value growth. For investors, holding common stock means sharing in the company’s profits and risks.
