beneficially owned financial

"Item 4. | Ownership (a) | Amount beneficially owned: 529,003.00"

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

"Sole power to vote or to direct the vote: 529,003.00"

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.

sole dispositive power financial

"Sole power to dispose or to direct the disposition of: 529,003.00"

Sole dispositive power is the exclusive legal authority to decide what happens to a security — for example, whether to sell, transfer, or retain shares — without needing anyone else’s permission. Investors care because it signals who truly controls the economic outcome of an investment: like holding the only key to a safe, the holder can realize gains or losses and may trigger regulatory reporting, insider rules, or influence over corporate ownership.

registered investment adviser financial

"Karpus is a registered investment adviser under Section 203"

A registered investment adviser (RIA) is a firm or individual legally registered with regulators to give personalized investment advice and manage clients' money, with a duty to put clients’ interests ahead of their own. Think of an RIA as a licensed financial guide who must disclose fees, conflicts and how they are paid; that transparency and legal duty matter to investors because it reduces the risk of hidden costs or biased recommendations.
