Key Terms

beneficial owner, open market, average price

3 terms

beneficial owner financial

"Following the reported transaction, the Reported Person is no longer a 10% beneficial owner."

A beneficial owner is the person who ultimately owns or controls a financial asset or property, even if their name isn't directly on official documents. Think of it like someone who secretly holds the keys to a safe deposit box—others may appear to have access, but the true owner is the one who benefits from what's inside. Identifying beneficial owners helps ensure transparency and prevent illegal activities like money laundering or fraud.

open market financial

"The shares were sold in the open market and the price reported is an average price."

An open market is a system where buying and selling of goods, services, or financial assets happen freely without restrictions or special controls. For investors, it means they can trade assets easily and quickly, which helps determine fair prices based on supply and demand. This environment encourages transparency and competition, making it easier to buy or sell with confidence.

average price financial

"The shares were sold in the open market and the price reported is an average price."
