beneficial ownership regulatory

"disclaims beneficial ownership of such shares"

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.

co-trustee regulatory

"is the co-trustee of the Lara Knuettel Revocable Trust"

pecuniary interest financial

"except to the extent of his pecuniary interest therein"
