Restricted Stock Units financial

"Each restricted stock unit ("RSU") represents a contingent right to receive one share"

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 equivalent rights financial

"Represents dividend equivalent rights in connection with the Issuer's dividend that accrue"

Dividend equivalent rights are promises that mirror the cash payments shareholders get from a company’s profits, but they are paid to holders of certain awards (like stock options or restricted stock units) rather than to actual shares. Think of them as a paycheck top‑up that matches dividends while the award is not yet a real stock, and they matter to investors because they add to employee compensation costs and potential share dilution, affecting company profitability and per‑share value.

pecuniary interest financial

"expressly disclaims beneficial ownership except to the extent of his pecuniary interest therein"

annual meeting of shareowners financial

"will vest on the earliest of the first anniversary of the grant date and the next annual meeting of shareowners"
