beneficially owned financial

"Item 4. | Ownership (a) | Amount beneficially owned: 4,200,856"

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

"Shared Voting Power 4,172,543.00"

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

"Shared Dispositive Power 4,200,856.00"

advisory clients financial

"The advisory clients of BAMCO and BCM have the right to receive"

parent holding company financial

"subsidiary Which Acquired the Security Being Reported on by the Parent Holding Company"

subsidiaries financial

"BAMCO and BCM are subsidiaries of BCG."

A subsidiary is a company that is majority-owned or controlled by a parent company but operates as a separate legal entity, like a branch or distinct shop under a bigger business umbrella. For investors, subsidiaries matter because their profits, debts, and risks can affect the parent’s overall financial health and value; understanding them helps reveal where revenue comes from, how risks are distributed, and how transparent the parent company’s performance really is.
