"Reported security as a Non-Qualified Stock Option (right to buy) exercised into common stock"

derivative security financial

"Transaction described as an exercise or conversion of derivative security"

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.

open market or private transaction financial

"Sale in open market or private transaction for the common stock sale"
