dividend equivalent rights financial

"dividend equivalent rights ("DERs") in connection with the Issuer's quarterly dividend"

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.

restricted stock units financial

"restricted stock units ("RSUs") held by the Reporting Person"

Restricted stock units are a type of company reward where employees are promised shares of stock, but they only fully own these shares after meeting certain conditions, like staying with the company for a set time. They matter because they can become valuable assets and are often used to motivate employees to help the company succeed.

deferred share units financial

"deferred share units ("DSUs") credited to the Reporting Person's deferred compensation account"

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.
