"Price represents the weighted average sale price of the shares sold."
beneficial ownership financial
"Each Reporting Person disclaims beneficial ownership of the securities except..."
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
"disclaims beneficial ownership of the securities except to the extent of his or its respective pecuniary interest"
