Rule 10b5-1 trading plan regulatory
"This sale was effected pursuant to a Rule 10b5-1 trading plan previously adopted"
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.
revocable living trust financial
"a revocable living trust, of which the Reporting Person is trustee and sole"
weighted average price financial
"The price reported is a weighted average price. These shares were sold"
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.
Class B Common Stock financial
"Each share of Class B Common Stock is convertible, at any time at the option"
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.
permitted transferee regulatory
"transfers to any "permitted transferee" as defined in, the Issuer's restated"
restated certificate of incorporation regulatory
"as defined in, the Issuer's restated certificate of incorporation in effect"
A restated certificate of incorporation is an updated, single-document version of a company’s founding rules that folds together the original charter and all later changes into one clear set of terms — like replacing a patchwork manual with a clean, revised edition. Investors care because it clarifies ownership details, voting rights, share classes and other legal rules that affect control, dividends and how value is created or diluted, so it can change the risks and benefits of owning the stock.
