Common Units financial
"Consists of (i) 21,762,476 Common Units and an equivalent number of shares"
Common units are the basic ownership stakes in a company, limited partnership, or trust that function like common stock: they give holders a claim on profits and often voting rights. Think of them as the ordinary seats at a table—the most directly affected by the business’s success or failure, so they typically offer higher upside but carry greater risk than preferred claims or creditors, which matters to investors evaluating potential return and safety.
Class B common stock financial
"an equivalent number of shares of Class B common stock directly held"
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.
beneficial ownership financial
"may be deemed to share beneficial ownership of the securities directly held"
Beneficial ownership means the person or entity that actually enjoys the benefits of owning shares or other assets — such as receiving dividends, voting rights, or price gains — even if the legal title is held in another name. For investors it matters because knowing who truly controls and profits from a company reveals who can influence decisions, exposes potential conflicts of interest or hidden concentration of power, and affects transparency and risk in the stock.
pecuniary interest financial
"disclaim beneficial ownership of such securities except to the extent of its respective pecuniary interest therein"
