"Amount beneficially owned: 0 ** see Note 1 **"
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.
Investment Company Act of 1940regulatory
"investment companies registered under the Investment Company Act of 1940"
A U.S. federal law that sets the rulebook for pooled investment vehicles such as mutual funds, exchange-traded funds and similar money managers, requiring them to register with regulators, disclose holdings and fees, limit conflicts of interest, and follow governance standards. It matters to investors because these protections and transparency rules act like a referee and scoreboard, helping people compare funds, trust that managers follow fair practices, and spot hidden costs or risks.
disclaims beneficial ownershipregulatory
"Dimensional disclaims beneficial ownership of such securities"
dispositive powerregulatory
"Sole power to dispose or to direct the disposition of: 0"
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.
What does Dimensional Fund Advisors report for ZEUS ownership?
Dimensional reports 0 shares beneficially owned and 0.0% of the class. The filing states the shares are owned by Funds advised by Dimensional, and Dimensional disclaims beneficial ownership while noting advisory relationships may confer voting or investment power.
Does Dimensional claim voting or disposal power over ZEUS shares?
The filing lists 0 sole and shared voting power and 0 sole and shared dispositive power. It cautions that in advisory roles Dimensional may possess voting or investment power for securities owned by the Funds but disclaims beneficial ownership.
