"Each deferred stock unit represents a right to receive one share"

A deferred stock unit (DSU) is a promise from a company to give an employee or director the value of a share at a future date, paid in actual shares or cash when certain conditions are met (such as retirement or a set date). Think of it like a gift card that converts to company stock later; it aligns pay with long‑term performance and can affect future share count, compensation expense and potential cash needs, so investors watch DSUs for their impact on dilution and company finances.
