10b5-1 trading plan regulatory
"Sold pursuant to a 10b5-1 trading plan adopted by the Reporting Person"
A 10b5-1 trading plan is a pre-arranged strategy that allows company insiders to buy or sell company stock at set times, regardless of their current knowledge about the company's situation. It acts like a scheduled appointment for trading, helping prevent the appearance of impropriety or insider trading. This plan provides a way for insiders to sell or buy shares in a controlled, transparent manner, offering reassurance to investors about fair trading practices.
weighted average price financial
"Represents the weighted average price of the shares sold."
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 financial
"The reporting person disclaims beneficial ownership of these 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.
pecuniary interest financial
"except to the extent of his pecuniary interest therein."
