Stock Options (Right to Buy) financial
"security_title: "Stock Options (Right to Buy)""
Restricted Stock Units financial
"security_title: "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.
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.
dividend reinvestment plan financial
"Includes 133.982 shares acquired through a dividend reinvestment plan."
A dividend reinvestment plan lets shareholders automatically use cash dividends to buy more shares of the same company instead of receiving the money. It matters to investors because it turns regular payouts into a steady way to grow ownership and take advantage of compound returns—like having your savings automatically buy additional slices of a pie over time—while often reducing transaction costs and smoothing purchase timing.
fully vested and exercisable financial
"These stock options are fully vested and exercisable."
contingent right to receive one share financial
"Each restricted stock unit represents a contingent right to receive one share of Class A Common Stock."
