Deferred Share Units financial

"Each DSU represents the right to receive one common share of the Issuer."

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.

voting or dispositive rights financial

"the Reporting Person shall not have any voting or dispositive rights with respect to the underlying common shares"

termination date financial

"on the date that is 6 months following the Reporting Person's termination date"

Termination date is the specific calendar day when a contract, agreement, option or other legal arrangement stops being in effect and any remaining rights or obligations expire. For investors it matters because that date sets deadlines for exercising rights, receiving payments, closing positions or avoiding penalties—similar to the day a lease or warranty ends, after which parties no longer have the same protections or claims.

non-U.S. eligible participants financial

"Grants to non-U.S. eligible participants will be settled with no further action"
