The DFM settlement rules impose a clear obligation on brokerage firms regarding proceeds generated from securities sold for clients. Once a broker has executed a sale, it may deduct the applicable commissions and fees, but it must then pay the remaining sale proceeds to the client before the end of two days or before the end of the settlement period prescribed by the DFM , as applicable. Payment can be made using recognised methods such as an appropriately issued cheque or transfer to the client's account. Where the client does not request immediate receipt of the proceeds, the broker must credit the amount to the client's balance before the end of the settlement period for the securities sold. This requirement protects clients by preventing brokers from retaining sale proceeds beyond the permitted settlement timetable. The one-, three- and four-day alternatives do not reproduce the rule stated in the CISI/DFM material. Consequently, the prescribed period presented in option B—two days or the DFM settlement period—is the correct answer.
