"In this latest set of FAQs, DOL describes three different communications to participants about increased contributions, apparently from paid service providers.... The distinctions DOL may be hinting at in these FAQs, however, are not productive. The Final Rule is explicit in generally including recommendations about distributions as fiduciary advice, but says nothing about contributions ... As a matter of both statutory interpretation and retirement policy, contributions present a very different case from that of distributions. Given the benefits to both participants and the retirement system of increased contributions, retirement service providers should not be exposed to fiduciary claims if and when they recommend that participants increase contributions, even if it also serves the provider's economic interest for them to do so."
