beneficially owned financial

"Item 4. | Ownership (a) | Amount beneficially owned: 135,133"

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.

shared voting power financial

"6 | Shared Voting Power 135,133.00"

Shared voting power occurs when two or more parties jointly have the right to vote or decide how a block of company shares is cast, like co-owners who must agree before moving a piece of furniture. Investors care because who controls voting rights affects board elections, major corporate decisions and takeover outcomes, and shared control can alter regulatory disclosures and the practical influence any holder has over a company’s direction and value.

shared dispositive power financial

"8 | Shared Dispositive Power 135,133.00"

parent holding company financial

"If a parent holding company has filed this schedule, pursuant to (ii)(G)"

subsidiary financial

"AQR Capital Management, LLC is a wholly owned subsidiary of AQR Capital Management Holdings, LLC."

A subsidiary is a company that is controlled or owned by a larger company, known as the parent company. Think of it like a branch or division of a bigger organization; it operates separately but is ultimately guided by the parent. For investors, understanding subsidiaries helps clarify how a larger company is structured and where its resources and risks are concentrated.
