Question

What is the difference between a fiduciary and the suitability standard?

Answer

A fiduciary is legally required to act in the client’s best interest at all times. The suitability standard, which historically applied to some broker-dealers, only requires that a recommendation be suitable — meaning appropriate — not that it be the best available option for the client. That distinction can shape every recommendation a prospect receives, from the funds selected to the products sold. Mercer Advisors operates under the fiduciary standard on all advisory work. Understanding which standard applies to a given advisor is one of the most important structural questions a prospect can ask.
