4 terms

Dividend Equivalent Units ("DEUs") financial

"Consists of dividend equivalent units ("DEUs") accrued on restricted stock units"

restricted stock units ("RSUs") financial

"accrued on restricted stock units ("RSUs") and/or deferred stock units"

Restricted stock units (RSUs) are a company promise to give an employee shares of stock (or cash equivalent) in the future, but only after certain conditions—usually staying with the company for a set time or hitting performance goals—are met. Investors watch RSUs because when they vest they increase the number of shares outstanding and can lead insiders to sell shares, affecting share price, company dilution and the true cost of employee pay.

deferred stock units ("DSUs") financial

"and/or deferred stock units ("DSUs") previously granted"

vesting financial

"will vest and be settled on the same terms and conditions"

Vesting is the process by which you earn full ownership of something, like company stock or a retirement benefit, over time. It’s like earning the right to keep a gift piece by piece the longer you stay with a company, making sure employees stay committed before they receive all the benefits.
