Rule 10b5-1 trading plan regulatory

"Sale was effected pursuant to a Rule 10b5-1 trading plan adopted"

A Rule 10b5-1 trading plan is a pre-arranged schedule that allows company insiders to buy or sell stock at specific times, even if they have inside information. It helps prevent accusations of unfair trading by making these transactions look planned and transparent, rather than sneaky or illegal.

beneficial ownership regulatory

"Reporting Person disclaims beneficial ownership except to the extent"

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 except to the extent of his pecuniary interest"

indirect ownership financial

"Reporting Person is the beneficial onwer of such shares by virtue"

immediate family other

"held by certain members of Reporting Person's immediate family"
