Phantom Stock Units financial

"Represents phantom stock units previously elected by the reporting person to be received as deferred 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.

Deferred Compensation Plan financial

"under the Company's Board of Directors Deferred Compensation Plan"

A deferred compensation plan is an arrangement where an employer agrees to pay part of an employee’s pay or bonus at a later date instead of immediately, often to reduce current tax bills or to tie rewards to long-term performance. For investors it matters because these promises create future cash obligations and influence executive incentives and retention; they can affect a company’s reported liabilities, cash flow planning and the risk profile if the business faces financial trouble.

annual cash retainer fees financial

"in lieu of annual cash retainer fees under the Company's Board of Directors Deferred Compensation Plan"

economic equivalent financial

"Each share of phantom stock is the economic equivalent of one share of common stock"
