Brokerage (or Commission). It is customary to express the remuneration for the broker's time and efforts in negotiating and arranging the contract as a certain percentage of the money earned by the shipowner. (In marine insurance, the broker is generally paid a commission by the underwriter although the assured is the broker's client and the services are for the client.)
