Restricted Stock Unit financial

"Each Restricted Stock Unit represents a contingent right to receive one share of Issuer Common Stock."

A restricted stock unit is a promise from a company to give an employee shares of stock after certain conditions are met, like staying with the company for a set amount of time. It’s like earning a bonus that turns into company stock once you’ve proven your commitment, making it a way to motivate and reward employees.

Deferred Stock Unit financial

"Each Deferred Stock Unit represents a contingent right to receive one share of Issuer Common Stock."

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.

Non-Employee Director Compensation Program financial

"settled in shares of the Issuer's Common Stock either (i) on a date selected by the Reporting Person pursuant to the Issuer's Non-Employee Director Compensation Program"

contingent right financial

"represents a contingent right to receive one share of Issuer Common Stock."
