restricted stock units financial

"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.

Director Compensation Policy financial

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

stock option financial

"Stock Option (Right to Buy)"

A stock option is a contract that gives you the right to buy or sell a company's stock at a specific price within a certain time frame. People use them to potentially make money if the stock's price moves favorably or to protect against losses. It's like holding a coupon that can be used to buy or sell stock at a set price later on.
