A common question we get at Fiduciary Decisions is How Many Plans Offer Managed Accounts? The answer to that question is shown below and the conclusion is obvious:
Larger Plans are much more comfortable providing Managed Accounts to Participants. BUT we have seen an increase in Advisor Managed Accounts in the smaller end of the marketplace.
Why are larger plans sponsoring Managed Accounts at a greater rate? The answer to that lies in the impact that Managed Accounts can have on Retirement Incomes. For example, see the data below for a typical participant:
These assumptions produce a nice monthly income of $3,865 per month for the participant from their 401(k) plan. But the question is what will this amount become if the Managed Account can change behavior by doing the following:




The answer to that is shown in the chart below. Bottom Line: If the Managed Account can truly change behavior, it can have a dramatic impact on the Monthly Retirement Income of the participant: from $3865 per month in the base case to $5494 in the Managed Account case (an increase of 42%).
