bona fide gift financial
"transaction_code "G" is described as a "Bona fide gift" of Class A Common Stock"
A bona fide gift is a genuine, voluntary transfer of money, property, or benefits from one party to another made without expectation of repayment, services, or hidden conditions. Investors care because such gifts can affect company disclosures, related‑party transaction rules, tax treatment, and perceived conflicts of interest; think of it like someone giving you a present with no strings attached — but on a corporate scale, auditors and regulators need to verify it really is unconditional.
pecuniary interest financial
"the reporting person has no pecuniary interest in the shares held by CZ Biohub"
beneficially owned financial
"Chan Zuckerberg Holdings entities are described as beneficially owned by the reporting person"
Beneficially owned describes securities or assets where a person has the economic rights and control—such as the right to receive dividends and to direct voting—even if legal title is held in another name. Think of it like having the keys and using a car that’s registered to someone else: you get the benefits and make decisions. Investors care because beneficial ownership reveals who truly controls value and voting power, affecting corporate decisions and takeover dynamics.
Class B Common Stock financial
"The Class B Common Stock is convertible into the issuer's Class A Common Stock"
A class B common stock is one of multiple types of a company’s ordinary shares that carries specific rights—often different voting power or dividend priority—compared with other classes. For investors it matters because those differences affect how much influence you have over company decisions, the income you might receive, and how freely the shares trade; think of it like owning a car with different keys: some keys let you start the engine and open the trunk, others only unlock the door.
voting and investment power financial
"the reporting person is deemed to have sole voting and investment power over these securities"
