"Represents a grant of restricted stock units received by the Reporting Person pursuant to the Issuer's Director Compensation Policy."
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.
