restricted stock units financial

"restricted stock units ("RSUs") granted on September 30, 2026"

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 stock units financial

"deferred stock units ("DSUs") granted under the Issuer's 2012 Incentive Compensation Plan"

Deferred stock units are promises from a company to give an employee shares of stock at a future date, often after certain conditions are met or after leaving the company. They function like a form of delayed compensation, allowing employees to earn shares over time. For investors, they represent potential future ownership in the company, but do not provide immediate voting rights or dividends until the shares are actually received.

separation from service financial

"issued upon Mr. Friedberg's separation from service with the Issuer"
