For a broker to execute an order on behalf of another broker. Giving up occurs as a professional courtesy when a broker receives an order from a client that he/she is too busy to execute. It is important to note that the broker who receives the order, rather than the broker who conducts the transaction, is the one who earns the applicable commissions and fees. The term originates from the fact that the broker who executes the transaction must "give up" the commission to other broker.
