Performance Share Units financial

"Award of Performance Share Units pursuant to the 2018 Omnibus Incentive Plan"

Performance share units are a type of company stock award given to employees that depend on the company meeting specific goals or targets. If these goals are achieved, the employee receives shares or the value of shares; if not, they may receive little or no compensation. This aligns employees’ interests with the company's success and encourages performance that benefits investors.

Restricted Stock Units financial

"Grant of Restricted Stock Units pursuant to the 2018 Omnibus Incentive Plan"

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.

Premium Priced Stock Option financial

"Premium Priced Stock Option with exercise price 10% above the closing market price"
