PHANTOM STOCK UNITS financial

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

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.
