Dividend Equivalent Rights financial

"The dividend equivalent rights accrued on previously awarded deferred stock units"

Dividend equivalent rights are promises that mirror the cash payments shareholders get from a company’s profits, but they are paid to holders of certain awards (like stock options or restricted stock units) rather than to actual shares. Think of them as a paycheck top‑up that matches dividends while the award is not yet a real stock, and they matter to investors because they add to employee compensation costs and potential share dilution, affecting company profitability and per‑share value.

deferred stock units financial

"accrued on previously awarded deferred stock units ("DSUs") and vest proportionately"

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.

economic equivalent financial

"Each dividend equivalent right is the economic equivalent of one share"
