Phantom Stock Units financial

"46.3 Phantom Stock Units credited to her account"

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

"Deferred Compensation Plan for Directors"

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.
