beneficially owned financial

"Item 4. | Ownership (a) | Amount beneficially owned: 0"

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.

Sole Voting Power financial

"5 | Sole Voting Power 0.00"

Sole voting power is the exclusive right to cast votes attached to a shareholder’s stock without needing approval from anyone else. Like holding the only remote control for a TV, it lets that holder decide corporate matters such as board members, mergers, and policy changes, making it important to investors because it concentrates control and can strongly influence a company’s strategy and the value of its shares.

Shared Dispositive Power financial

"8 | Shared Dispositive Power 0.00"

parent holding company financial

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

subsidiary financial

"Identification and Classification of the Subsidiary Which Acquired the Security"

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.
