Dividend Equivalent Rights financial

"The dividend equivalent rights ("DERs") accrued with respect to additional"

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.

restricted stock units financial

"accrued with respect to additional restricted stock units ("RSUs") credited"

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.

deferred compensation financial

"RSUs credited to the reporting person with respect to deferred compensation."

Deferred compensation is pay that employees or executives have earned now but will receive at a later date, such as delayed bonuses, retirement benefits, or stock grants. It matters to investors because it creates future obligations and shapes incentives—like a promise to pay later that can affect a company’s reported profits, cash needs and potential stock dilution—so it helps signal how a business manages costs and retains key people.
