3 terms

dividend equivalents financial

"Accrual of dividend equivalents on deferred shares."

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 shares financial

"Accrual of dividend equivalents on deferred shares."

Deferred shares are a class of stock whose economic benefits or certain shareholder rights are delayed or paid later than ordinary shares—for example, dividends may be paid only after other shareholders receive theirs, or voting or redemption rights may be postponed. For investors, that timing difference matters because deferred shares typically offer lower near-term income and different risk, affecting expected returns, priority in payouts, and the share’s market value; think of them like a delayed paycheck compared with a regular salary.
