5 terms

weighted average purchase price financial

"This constitutes the weighted average purchase price. The prices range from"

The weighted average purchase price is the average cost per share you paid across multiple buys, calculated so larger purchases count more than smaller ones. Imagine buying apples at different prices: the overall price you effectively paid depends on how many apples you bought at each price. Investors use it to measure true cost basis, calculate gains or losses, decide when to sell, and manage taxes and portfolio performance.

pecuniary interest financial

"except to the extent of its pecuniary interest, if any, therein"

commingled investment vehicles financial

"These securities are owned directly by various commingled investment vehicles"

beneficial ownership regulatory

"The Reporting Person disclaims beneficial ownership of the securities"

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.

indirect ownership regulatory

"ownership type recorded as indirect through managed investment vehicles"
