Rule 10b5-1 trading plan financial
"exercise of stock options and sale of the resulting shares of common stock was pursuant to a pre-arranged 10b5-1 trading plan"
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
"This transaction was executed in multiple trades at prices within a range. The price reported above reflects the 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.
family trusts financial
"Shares held in family trusts as to which the Reporting Person shares investment power and the Reporting Person and/or immediate family members are beneficiaries."
