Phantom Stock Units financial

"phantom stock units were allocated under the Deferred Compensation Plan for Non-Employee Directors"

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 Restricted Stock Units financial

"deferred restricted stock units were allocated under the 2009 Non-Employee Director Stock Incentive Plan"

Deferred restricted stock units are promises by a company to give employees or executives company shares at a future date, subject to conditions like continued employment or performance targets; the delivery and tax event are intentionally delayed. They matter to investors because they affect when new shares may be issued and how executives are motivated—like a paycheck held in escrow that vests over time, influencing potential share dilution and management behavior.
