4 terms

weighted average price financial

"The price reported is a weighted average price."

Weighted average price is the average price of a security where each trade or component is counted according to its size, so bigger trades pull the average more than smaller ones. Think of it like calculating the average cost of a grocery haul where items you bought more of have greater influence on the final per-item cost. Investors use it to understand the true average price paid or received, judge execution quality, and compare trading performance against market movement.

beneficial ownership regulatory

"disclaims beneficial ownership of the shares reported herein"

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 regulatory

"except to the extent of its pecuniary interest therein"

separately managed account financial

"Securities owned by a separately managed account"

A separately managed account (SMA) is a personalized investment portfolio owned by a single investor and run by a professional manager who buys and sells securities on that investor’s behalf. It matters to investors because an SMA offers tailored asset selection, tax handling, and transparency—like hiring a personal chef who prepares meals to your dietary needs rather than sharing a set menu—so you can align holdings with your goals and see exactly what you own.
