beneficially owned financial

"aggregate number of Shares and percentages of the Shares beneficially owned by each"

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 11,342,025.00"

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 11,342,025.00"

Schedule 13D regulatory

"filed a statement on Schedule 13D to report the acquisition"

A Schedule 13D is a legal document that investors file with regulators when they buy a large enough stake in a company to potentially influence its management or decisions. It provides details about the investor’s intention, ownership stake, and plans, helping other investors understand who is gaining control and what their motives might be.

Form N-CSRS regulatory

"Shares outstanding as reported in the Issuer's Form N-CSRS"

Form N-CSR is a standardized, certified shareholder report that registered investment funds file with the U.S. Securities and Exchange Commission to disclose audited financial statements, portfolio holdings, results and management commentary. For investors it serves like a fund’s official report card and audited financial statement—helping verify transparency, spot shifts in strategy or risk, and compare funds when deciding where to put money.
