dividend equivalent rights financial

"Represents dividend equivalent rights ("DERs") in connection with the Issuer's quarterly dividend"

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.

DERs financial

"Each DER is the economic equivalent of one share of Issuer's common stock"

restricted stock units ("RSUs") financial

"accrued to the Reporting Person on restricted stock units ("RSUs") held by the Reporting Person"

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.
