Phantom Stock Units financial

"security_title: "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.

directors deferred compensation plan financial

"accrued under the Sonoco Products Company directors deferred compensation plan"

A directors deferred compensation plan lets a board member postpone receiving part or all of their cash fees or stock-based pay until a future date, often retirement, allowing taxes to be delayed and payouts to be structured over time. Investors care because these plans change a company’s future cash obligations and reveal how the board’s pay is aligned with long-term performance—like choosing to take a paycheck later to tie personal reward to the company’s future results.
