beneficial ownership regulatory
"SRB disclaims beneficial ownership of the shares of Common Stock reported"
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.
dispositive power regulatory
"may be deemed to have voting and dispositive power over the shares of Common Stock"
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.
pecuniary interest financial
"PRC disclaims beneficial ownership of the shares except to the extent of its pecuniary interest"
