beneficially owned financial

"Amount beneficially owned: See the response(s) to Item 9 on the attached"

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 4,846,632.00 7 | Sole Dispositive Power 0.00"

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 4,908,581.00 9 4,908,581.00"

holding company financial

"12 HC, Morgan Stanley & Co. International plc 2 |"

A holding company is an organization that owns enough shares of other businesses to control them but usually does not run their day-to-day operations. Think of it as an umbrella or parent that lets investors gain exposure to several companies through one vehicle; its value depends on the performance, risks, dividends and debts of the companies it holds, so it matters for assessing diversification, control and consolidated financial health.
