Phantom Stock financial

"Each share of phantom stock is the economic equivalent"

A phantom stock is a form of compensation that gives employees or executives the benefits of stock ownership, such as the increase in stock value, without actually giving them real shares. It acts like a promise to pay the employee the equivalent value of company stock later, often as a bonus or incentive. This allows companies to motivate and reward staff without diluting ownership or transferring actual shares.
