4 terms

restricted stock units financial

"A portion of the Reporting Person's restricted stock units (6,081) granted on June 11, 2025, vested"

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 liability financial

"Upon vesting, 1,770 restricted stock units were withheld to satisfy the Reporting Person's tax liability"

tax-withholding disposition financial

"transaction_action: "tax-withholding disposition" for 1,770.0000 shares"

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.

Form 4 regulatory

"INSIDER FILING DATA (Form 4): { "issuerName": "AMERICAN ELECTRIC POWER CO INC""

Form 4 is a official document that company insiders, such as executives or major shareholders, file with regulators whenever they buy or sell company shares. It provides transparency about how those with inside knowledge are trading, helping investors see if insiders are confident in the company's prospects or may be selling for personal reasons. This information can influence investor decisions by revealing insiders' perspectives on the company's value.
