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.

weighted average price financial

"The price 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.

immediate family financial

"Members of the reporting person's immediate family are beneficiaries of the trust."

trustees financial

"her husband are trustees of the trust that holds the reported securities."

Trustees are people or a small group legally appointed to hold and manage assets, documents, or obligations on behalf of others and must act in those beneficiaries’ best interests. Think of them as a neutral guardian or custodian who enforces rules, protects assets, and makes decisions that can affect payments, corporate governance, or recovery in a default — all of which directly influence investor returns and risk.
