restricted stock units ("RSUs") financial
"Represents a grant of restricted stock units ("RSUs"). The RSUs vest on the date immediately preceding the next occurring annual meeting"
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.
grantor retained annuity trust financial
"By 2024 grantor retained annuity trust"
A grantor retained annuity trust (GRAT) is an estate-planning tool where the person who creates the trust transfers assets into it but receives fixed cash payments (an annuity) from the trust for a set number of years; whatever remains after that term passes to designated beneficiaries. It matters to investors because it can shift future appreciation of assets out of the creator’s taxable estate—like putting an asset into a timed vending machine that pays you fixed amounts while any extra value that grows inside the machine goes to heirs with reduced gift or estate tax consequences.
family irrevocable trust financial
"By family irrevocable trust"
beneficial owner financial
"he may be deemed to be the beneficial owner of, and to have a pecuniary interest in, such shares"
A beneficial owner is the person who ultimately owns or controls a financial asset or property, even if their name isn't directly on official documents. Think of it like someone who secretly holds the keys to a safe deposit box—others may appear to have access, but the true owner is the one who benefits from what's inside. Identifying beneficial owners helps ensure transparency and prevent illegal activities like money laundering or fraud.
pecuniary interest financial
"disclaims beneficial ownership of such shares, except to the extent of any pecuniary interest therein"
