Key Terms

restricted stock unit, dividend equivalents, ordinary share, vesting

4 terms

restricted stock unit financial

"Includes 5,392 restricted stock unit awards. Each restricted stock unit represents a contingent right"

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.

dividend equivalents financial

"additional restricted stock units accrued as dividend equivalents based on the Issuer's quarterly dividend"

Payments tied to employee or contractor equity awards that mirror the cash dividends paid on the company’s stock; they give the holder the same economic benefit as owning the shares without transferring actual shares—often paid in cash or additional award units when the award becomes payable. Investors care because these payments affect a company’s compensation costs, cash flow and potential share dilution, and they signal how management is being rewarded and aligned with shareholders.

ordinary share financial

"Issuer's quarterly dividend of $0.4523 per ordinary share"

An ordinary share is a unit of ownership in a company that gives the holder a stake in its profits and usually the right to vote on key decisions. Think of it like a slice of a pizza where each slice entitles you to a portion of what’s left after bills are paid; value can rise or fall with the business and may pay dividends, so it matters to investors for income, growth and control.

vesting financial

"The RSUs are scheduled to vest in three equal annual installments"

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.
