Another good article on the fiduciary rule. 'Acting as a fiduciary means you're doing what's in the best interest of clients, said Tim Quillin, a partner with Aptus Financial in Little Rock. It's a higher level of accountability than the suitability standard used by brokers, planners and insurance agents who work with retirement accounts. "It's a little sad that we need regulations to define investment advisers as fiduciaries to retirement plans," Quillin said. "That should be fundamental to what our goal is as an investment adviser."'
