The DOL’s much anticipated (or maligned depending on the audience) Fiduciary Rule expands the definition of what constitutes investment advice under ERISA and thereby increases the number and types of retirement plan service providers that are considered ERISA fiduciaries (see our prior coverage of the Fiduciary Rule here, here and here). It also imposes stringent compliance and disclosure requirements in order for those service providers to avoid breaching their ERISA fiduciary duties.
