Phantom Stock Units financial

"security_title: "Phantom Stock Units""

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.

Stock Units financial

"Stock Units are paid to the director in cash or shares upon termination of service"

Stock units are individual pieces of ownership in a company, like slices of a pie that together make up the whole business. They matter to investors because each unit represents a claim on the company’s assets, profits and sometimes voting power, and changes in the number or value of these units affect ownership percentages, potential dividends and share dilution — all of which influence an investment’s worth.

How and when are AEP phantom stock units for directors like Von Thaer paid out?

AEP phantom stock units are paid in cash or shares when the director’s service ends, unless the director elects to defer payment further. Any deferral election must still start payments no later than five years after termination of service, according to the disclosed plan terms.
