Rule 10b5-1 plan regulatory
"This transaction was effected pursuant to a written Rule 10b5-1 plan adopted by the reporting person on November 11, 2025."
A Rule 10b5-1 plan is a prearranged, written schedule that lets corporate insiders buy or sell company stock at set times or amounts, even if they later learn material nonpublic information. Think of it like setting an automatic thermostat for trades: it creates a clear record that trades were planned in advance, reducing the risk of insider-trading accusations and helping investors trust that insider transactions are routine rather than based on secret information.
weighted average price financial
"This price represents the weighted average price of sale transactions that were executed in multiple trades at prices ranging from $80.00 to $80.99 per share."
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.
Stock Option (Right to Buy) financial
"Stock Option (Right to Buy) with underlying security title Common Stock and 23,749.0000 underlying security shares."
derivative security financial
"Exercise or conversion of derivative security as described in the transaction code description."
A derivative security is a financial contract whose value comes from the price or performance of something else, such as a stock, bond, commodity, or market index. For investors it acts like an insurance policy or a wager: it can be used to protect against losses, lock in prices, or amplify gains and losses, so it can change a portfolio’s risk and potential return without owning the underlying asset directly.
indirect ownership financial
"Common Stock reported with ownership_type indirect and nature_of_ownership By Spouse."
