4 terms

Schedule 13D regulatory

"This Amendment No. 4 amends and supplements the originally filed Schedule 13D"

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.

beneficially owned financial

"Aggregate amount beneficially owned by each reporting person 0.00"

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.

pro rata distribution financial

"Mithril I effected a pro rata distribution without additional consideration"

A pro rata distribution is when a company or organization shares out money, assets, or benefits evenly among all eligible people based on their size or share. For example, if a company makes a profit and distributes it to shareholders, each person gets a portion proportional to how many shares they own. It ensures everyone gets their fair part based on their ownership or stake.

dispositive power financial

"Sole Dispositive Power 0.00 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.
