Phantom Stock Units financial

"46.3000 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.

Deferred Compensation Plan for Directors financial

"pursuant to the Issuer's Deferred Compensation Plan for Directors"

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.
