Key Terms

4 terms

restricted stock units financial

"Includes 4,537 restricted stock units which will vest on the earlier"

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.

dividend equivalents financial

"restricted stock unit award, additional restricted stock units accrued as dividend equivalents"

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.

cessation of service other

"settled in ordinary shares following the Reporting Person's cessation of service"

Deferred Compensation Plan financial

"terms of the WestRock Company 2016 Deferred Compensation Plan for Non-Employee Directors"

A deferred compensation plan is an arrangement where an employer agrees to pay part of an employee’s pay or bonus at a later date instead of immediately, often to reduce current tax bills or to tie rewards to long-term performance. For investors it matters because these promises create future cash obligations and influence executive incentives and retention; they can affect a company’s reported liabilities, cash flow planning and the risk profile if the business faces financial trouble.
