Phantom Stock Units financial
"Transaction in "Phantom Stock Units" reported as equity-based compensation."
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.
Employee Stock Ownership Plan ("ESOP") financial
"Shares held in the Employee Stock Ownership Plan ("ESOP") account."
contingent right financial
"Each phantom stock unit represents a contingent right to receive one share."
