Phantom Stock Units financial
"Represents stock units credited to the Reporting Person's account as of March 28, 2026"
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.
Deferred Compensation Plan for Directors financial
"pursuant to the Issuer's Deferred Compensation Plan for Directors (the "Plan")"
A deferred compensation plan for directors is an arrangement that lets board members postpone receiving part of their pay until a later date—often retirement or a set future time—so the money can grow or be paid under specified conditions. Think of it like directing a portion of your paycheck into a locked savings account that pays out later; investors care because it creates future cash or stock obligations, signals how the company motivates and retains leadership, and can affect shareholder value through timing of payouts or potential dilution.
Common Stock units financial
"Directors' retainers are deferred quarterly under the Plan as Common Stock units"
change of control financial
"The shares are distributable as stock upon cessation of director service (for any reason) or a change of control."
A change of control occurs when the ownership or management of a company shifts significantly, such as through a sale, merger, or acquisition, resulting in new leadership or ownership structure. This change can impact the company's direction and decision-making, which is important for investors because it may affect the company's stability, strategy, and future prospects.
