FSA has carried out a post-implementation review of the changes it made to its dealing commission rules. It is pleased the rules are having the desired effect, although there are some areas where firms could still improve. Overall, the performance indicators found that the expected changes were occurring and that the market was moving towards delivering the intended outcomes. Commission rates have fallen and the new regime has limited the use of dealing commission to the purchase of execution and research, encouraged greater separation in the purchase of execution and research and improved the provision of information. FSA found the retail markets were benefitting as well as the wholesale ones. Its concern was that there was limited evidence disclosures were being used, and it would like to see more disclosures provided.
