Restricted Stock Units financial

"Represents restricted stock units granted under the 2016 Non-Employee Directors' Long-Term Equity Compensation 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.

Phantom Stock Units financial

"Represents deferral of vested restricted stock units as deferred compensation under the 2016 Non-Employee Directors' Long-Term Equity Compensation Plan."

Phantom stock units are company promises that pay a cash or stock-equivalent award tied to the firm’s share price or value growth, but they do not issue actual shares. Think of them as a bonus check that moves with the stock like a mirror rather than handing over an ownership slice. Investors care because these awards can affect a company’s future cash obligations, executive incentives and reported expenses without causing share dilution.

deferred compensation financial

"Represents deferral of vested restricted stock units as deferred compensation under the 2016 Non-Employee Directors' Long-Term Equity Compensation Plan."

Deferred compensation is pay that employees or executives have earned now but will receive at a later date, such as delayed bonuses, retirement benefits, or stock grants. It matters to investors because it creates future obligations and shapes incentives—like a promise to pay later that can affect a company’s reported profits, cash needs and potential stock dilution—so it helps signal how a business manages costs and retains key people.
