beneficially owned financial

"Amount beneficially owned: Westchester Capital Management, LLC: 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.

dispositive power financial

"Sole Dispositive Power 0.00 8 | Shared Dispositive Power 0.00"

Dispositive power is the authority to decide the final outcome of an asset, legal claim, contract, or corporate action — in effect the power to dispose of or resolve something. For investors it matters because whoever holds that authority can determine who gets paid, who controls an asset or vote, and how risks and returns are allocated; think of it like holding the key that lets you lock in the winner or loser in a deal.

registered investment adviser financial

"Virtus, a registered investment adviser, serves as the investment adviser"

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.

Ownership of 5 percent or Less of a Class financial

"Item 5. | Ownership of 5 Percent or Less of a Class."
