Dividend Equivalent Rights financial

"The dividend equivalent rights accrued in respect of the reporting person's deferred share 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 share units financial

"The dividend equivalent rights accrued in respect of the reporting person's deferred share units"

Deferred share units are promises that give an executive or director the right to receive company shares or their cash value at a future date, often when they retire or leave the company. Think of them as a paycheck held in a savings account that converts into stock later; they matter to investors because they tie pay to long-term performance, create potential future dilution of shares, and represent a delayed cash or share obligation the company must eventually fulfill.
