On September 7, 2017, the U.S Chamber of Commerce hosted an event, Fiduciary Duty: Assessing the Real-World Impact, to discuss the effects of the Department of Labor’s (DOL’s) Fiduciary Rule. When the DOL promulgated the final rule in April 2016, it had to guess about the rule’s effects on retirement investors and the marketplace. Today, instead of guessing, we have facts. At the event, the U.S. Chamber and five other organizations presented new research on the impact that partial implementation of the rule had on financial institutions and investors.
