Phantom Stock financial

"Each share of phantom stock is the economic equivalent of one share of common stock"

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.

economic equivalent financial

"Each share of phantom stock is the economic equivalent of one share of common stock"

deferred compensation plan financial

"represents director compensation deferred in the form of common stock pursuant to the issuer's deferred compensation plan"

A deferred compensation plan is an arrangement where an employer agrees to pay part of an employee’s pay or bonus at a later date instead of immediately, often to reduce current tax bills or to tie rewards to long-term performance. For investors it matters because these promises create future cash obligations and influence executive incentives and retention; they can affect a company’s reported liabilities, cash flow planning and the risk profile if the business faces financial trouble.

termination of service financial

"become payable in the form of common stock upon the reporting person's termination of service"
