Class B Common Stock financial
"The 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.
pro rata financial
"distributed to its limited partners and sole general partner, pro rata and"
Pro rata means dividing or distributing something proportionally based on a specific factor, such as ownership or contribution. For example, if an investor owns 10% of a company, they would receive 10% of any dividends or benefits allocated. This approach ensures everyone gets their fair share relative to their stake or input, helping investors understand how benefits, costs, or responsibilities are fairly shared.
Rule 16a-9(a) regulatory
"distributions were made in accordance with the exemptions afforded by Rule 16a-9(a)"
Rule 16a-13 regulatory
"exemptions afforded by Rule 16a-9(a) and Rule 16a-13 of the Securities"

"disclaims beneficial ownership of the shares held of record, except to the extent of its or his pecuniary interest"

"has voting and investment power over the shares held by each of the Thrive Capital Funds"
