dividend-equivalent stock units financial

"automatic accrual of dividend-equivalent stock units"

Dividend-equivalent stock units are compensation units that track the dividend payments an investor would receive on a share, but are paid to an employee or holder in cash or additional units instead of actual shares. They matter to investors because they represent a company obligation that can affect cash flow and shareholder dilution over time, and they reveal how a company rewards insiders in ways that mimic its dividend policy — like giving a paycheck that follows the company’s dividend stream.

restricted stock units financial

"on the reporting person's restricted stock units"

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.
