4 terms

Dividend Equivalents (DEs) financial

"These shares include 1,273 Dividend Equivalents (DEs) granted pursuant to the Amgen Inc. Second Amended and Restated 2009 Equity Incentive Plan"

Restricted Stock Units financial

"DEs are credited to the reporting person's unvested Restricted Stock Units and are paid out in shares"

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.

Equity Incentive Plan financial

"granted pursuant to the Amgen Inc. Second Amended and Restated 2009 Equity Incentive Plan"

An equity incentive plan is a program that gives employees, executives or directors the right to receive company stock or options to buy stock as part of their pay. Think of it as offering slices of future company profit to motivate people to boost long‑term performance; for investors it matters because it can align employee goals with shareholder value but also increases the number of shares outstanding, which can dilute existing ownership.

tax-withholding disposition financial

"transaction_action: tax-withholding disposition"

A tax-withholding disposition is an event or transaction—such as selling or transferring securities, exercising options, or receiving compensation—that triggers a requirement to hold back part of the payment and remit it to tax authorities. It matters to investors because it reduces the cash they receive immediately and can change the timing and amount of taxable income, like a cashier taking a portion of your sale proceeds to pay taxes before you get the rest.
