This thread illustrates why it is not a good idea to have the corporate plan sponsor be the plan administrator. The Department of Labor can assert that every individual director and executive officer is a fiduciary personally based on the formal identification of the plan sponsor plan administrator, and it has done so. In the end, the argument that there is a very clear and well defined (by practice) limited number of persons who are the functional fiduciaries will probably control the personal liability questions, but it will be rather uncomfortable for those poor formal fiduciaries to suffer through the process with the liability cloud over their heads and the outcome is uncertain.
