Rule 10b5-1 trading plan financial
"Shares were sold pursuant to a Rule 10b5-1 trading plan adopted by the Reporting Person on December 1, 2025."
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.
weighted average price financial
"The price reported in Column 4 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.
limited partnership financial
"Shares held by a limited partnership of which the Reporting Person is a trustee of a trust which is the general partner."
A limited partnership is a legal business structure with two types of partners: at least one general partner who runs the business and bears full legal responsibility, and one or more limited partners who contribute money, share profits, and have liability capped at their investment. For investors, it matters because it separates control from financial exposure — like putting money into a store without managing it — and affects how returns, risks, taxes and transferability of ownership are handled.
irrevocable trust financial
"Shares held by an irrevocable trust of which the Reporting Person is a Trustee."
An irrevocable trust is a legal arrangement where an owner transfers assets into a separate entity managed by a trustee and gives up the power to modify or reclaim those assets. For investors it matters because putting stock or other holdings into such a trust can change who controls and benefits from the assets, affect taxes and creditor protection, and influence how easy it is to sell or value those holdings—like placing valuables in a locked safe overseen by someone else.
pecuniary interest financial
"The Reporting Person disclaims beneficial ownership in these shares except as to the Reporting Person's pecuniary interest therein."
