beneficial ownership financial

"The Shares to which this relates are owned directly by the accounts managed by Karpus."

Beneficial ownership means the person or entity that actually enjoys the benefits of owning shares or other assets — such as receiving dividends, voting rights, or price gains — even if the legal title is held in another name. For investors it matters because knowing who truly controls and profits from a company reveals who can influence decisions, exposes potential conflicts of interest or hidden concentration of power, and affects transparency and risk in the stock.

sole voting power financial

"Sole Voting Power 670,404.00"

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 Dispositive Power 670,404.00"

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 of the Investment Advisers Act of 1940."

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.

informational barriers financial

"effective informational barriers have been established between Karpus and CLIG"
