The investment menu is ultimately what participants will use to grow their savings for retirement so its importance cannot be overstated.   The key to crafting a retirement plan investment menu is creating a balance between providing enough options for diversification and keeping the menu simple enough for participants to use easily. This is where choice plays a factor.

Studies have shown that too many choices in an investment menu can lead to poor diversification, procrastination, or "paralysis from analysis" – where participants will make no choice at all.  After all, they probably had to make around 2,000 choices before coming to work and being presented with information on their retirement plan.  Just thinking about making one more decision can be defeating – especially when the participant might not feel they have the expertise to make the right decision.

Utilizing an understanding of participant behavior and the daunting number of decisions facing the average human on any given day, plan sponsors should consider simplifying and designing investment menus around key objectives and organizing fund options into "tiers."

Tier 1 – Do It For Me

For the majority of participants, the thought of navigating even a simple core menu of funds can be overwhelming.

For those participants that want someone to "do it for me," it is best to guide them through the process of making an investment election based on their age or their expected date of retirement and then selecting the appropriate target date fund.

Another option is a risk-based model (i.e., conservative, moderate, aggressive).  Participants feel assured their account will be professionally managed.

The proliferation of target date fund usage over the past 10 years is a sign this tier is suitable for a large portion of the participant population.

Tier 2 – Help Me Do It

For the segment of the participant population that have the desire to spend time understanding and building their portfolio, it is a best practice to provide them with a simplified core menu of funds.

The challenge to plan sponsors is to provide enough options to deliver diversification, but also keep the menu easy enough for the average investor to understand.

A well-constructed menu might include 10 to 15 choices.

Tier 3 – Do It Myself

For some plan sponsors with seemingly sophisticated investing participants, they may want to provide additional choice.

While this isn't appealing to all plan sponsors, some find the ability to point participants to a brokerage window to purchase almost any investment option a benefit.

We find that the amount of participants that actually invest in a brokerage window is about 2 percent.

Take a streamlined approach

Our experience has shown that a streamlined approach to investment menu construction benefits both participants and plan sponsors.

Participants can focus on how much to save, which is arguably the most important determination they will make in having a successful retirement, versus combing through dozens of investment options.

Plan sponsors can also focus on monitoring the limited number of investment options and creating economies of scale to keep costs down.  Together this will create participants that are retirement ready and reduce the fiduciary liability of plan sponsors.
