3 terms

dividend equivalents financial

"Accrual of <b>dividend equivalents</b> on deferred stock units."

Payments tied to employee or contractor equity awards that mirror the cash dividends paid on the company’s stock; they give the holder the same economic benefit as owning the shares without transferring actual shares—often paid in cash or additional award units when the award becomes payable. Investors care because these payments affect a company’s compensation costs, cash flow and potential share dilution, and they signal how management is being rewarded and aligned with shareholders.

deferred stock units financial

"Accrual of dividend equivalents on <b>deferred stock units</b>."

Deferred stock units are promises from a company to give an employee shares of stock at a future date, often after certain conditions are met or after leaving the company. They function like a form of delayed compensation, allowing employees to earn shares over time. For investors, they represent potential future ownership in the company, but do not provide immediate voting rights or dividends until the shares are actually received.

quarterly Director retainer/fees financial

"Deferred share portion of <b>quarterly Director retainer/fees</b>."
