4 terms
Rule 10b5-1 trading plan financial
"The transactions reported in this Form 4 were effected pursuant to a Rule 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 sales price financial
"Represents the weighted average sales price per share. The shares sold at prices ranging"
Class B common stock financial
"In accordance with its terms, the Class B common stock automatically converted into Class A"
A class B common stock is one of multiple types of a company’s ordinary shares that carries specific rights—often different voting power or dividend priority—compared with other classes. For investors it matters because those differences affect how much influence you have over company decisions, the income you might receive, and how freely the shares trade; think of it like owning a car with different keys: some keys let you start the engine and open the trunk, others only unlock the door.
pecuniary interest financial
"disclaims beneficial ownership of the securities held by these persons and entities except to the extent of his pecuniary interest therein"
