I see two problems here. First, "if it walks like a duck, and quacks like a duck, it's a duck." What I mean by this is that the definition of "fiduciary" under ERISA is a functional defintion. If the individual is performing fiduciary functions, he/she is a fiduciary regardless of his/her title or what some document says. Once the broker starts providing "customized" information, he/she crosses the line and becomes a fiduciary. Second, I don't think the broker can legally provide "ongoing monitoring services", "customized Investment Policy Statement", or "fund specific advice" unless he/she has taken the next step and become a Registered Investment Adviser. So, (1) the broker is a plan fiduciary, and (2) he/she is doing something he/she is not licensed to do.
