The Financial Industry Regulatory Authority should pay arbitrators more, require explanations for arbitration decisions and implement an automatic mediation process to improve its ability to address customer and broker complaints against brokerage firms, a task force said Wednesday, Investment News reported. The primary way to improve the system is to increase arbitrator pay per hearing session from $300 to $500, the task force said. The 51 recommendations were made by a 13-member panel convened in June 2014 to analyze the arbitration system sponsored by the authority. FINRA operates dispute-resolution forums that draw from a pool of more than 6,400 arbitrators, some of whom come from the financial industry and others who are deemed “public” arbitrators.
