Key Terms

indirect interest, dispositive power, beneficial ownership, pecuniary interest

4 terms

indirect interest financial

"Reporting person maintains an indirect interest in these shares insofar as he is Managing Member"

dispositive power financial

"may be deemed to have shared voting and dispositive power over Common Stock held by"

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.

beneficial ownership financial

"disclaims beneficial ownership of the securities held by the Cruiser Funds and SMAs"

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.

pecuniary interest financial

"except to the extent of his pecuniary interest"
