Rule 10b5-1 trading plan financial
"The transactions were pursuant to a Rule 10b5-1 trading plan adopted by the Reporting Person."
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 is a weighted average price. The shares were sold in multiple transactions at prices ranging from..."
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.
pecuniary interest financial
"The Reporting Person is deemed to have voting and investment power ... but has no pecuniary interest in these shares."
non-derivative financial
"transaction_type": "non-derivative""
indirect ownership financial
"ownership_type": "indirect""
open-market sale financial
"transaction_action": "open-market sale""
An open-market sale is when a shareholder sells existing shares directly on a public exchange to any willing buyer, rather than through a private deal. Think of it like putting goods on a busy market stall where price is set by supply and demand; for investors it matters because such sales increase available supply, can put short-term downward pressure on the stock price, and signal changes in liquidity or investor confidence.
