On the surface, one would ask what the problem is. But once again, there are unintended consequences. I will give you one example:
Let's say you own a company that has 50 employees, and you have a 401k for your employees. And let's say I am the advisor on that plan, that helps you as owner, makes sure your plan in in compliance, and makes sure you have proper investment choices, etc. And let's say, in the past, I have come out twice a year to meet with your employees, offering them advice, education, etc as part of my service.
Then, let's say, that after 30 years working with you, Joe, your top guy, wants to retire, and he has 1,000,000 in the 401k. He has worked with me for the last 25 years. I have helped him with various financial matters, including education, maybe worked with an attorney in creating an estate plan, maybe helped him with some life insurance, and he wants to roll his 401k to an IRA with me at my firm. Guess what, he can't. That constitutes a conflict of interest under the new guidelines. There are many equally silly rules that I don't have time to get into, but there are many that are leaving us shaking our heads.
