Form 144 regulatory

"Class A Common | Goldman Sachs & Co. LLC 200 West Street"

Form 144 is a document that investors must file with the government when they plan to sell a large number of shares of a company's stock. It helps ensure transparency so everyone knows how many shares are being sold and when, which can impact the stock's price.

Class A Common financial

"Class A Common | 03/20/2013 | Acquired Class B common shares"

conversion clause legal

"Class B common shares to be converted to Class A common shares"

broker-dealer market

"Goldman Sachs & Co. LLC 200 West Street New York NY"

A broker-dealer is a licensed firm or individual that both executes trades on behalf of clients (acting as a broker) and buys or sells securities for its own account (acting as a dealer). Investors care because broker-dealers provide the plumbing of markets — they place orders, hold or move cash and securities, offer research or advice, and their stability and fees directly affect trade execution, costs, and the safety of client funds; think of them as a combined travel agent and taxi for your investments.
