Reenrollment strategies: Ensuring no participant is left behind

May 28, 2025 | BlackRock Retirement Perspectives

Two individuals sit in blue chairs with laptops, discussing retirement and reenrollment strategies for future planning.

Key points

  • 01

    Consider reenrollment to retain legacy populations

    Thoughtfully designed defined contribution plans, with a carefully selected default option, help encourage savings, create diversification and build retirement security.

  • 02

    Help participants manage their asset allocation

    Very few participants have the expertise to manage their own asset allocation. Even those who do may not review or adjust their investments over time. Reenrollment can help address these issues.

    Spot scenarios to spur reenrollment

    Reenrollment can get participant populations aligned with your current retirement plan best practices. Scenarios like a new target date fund being the default investment option for new hires only, concentrating of inappropriate risk, following a merger or acquisition are all times to consider reenrollment.

Limiting new defaults and plan design innovations to new hires creates two separate and unequal participant populations: those who benefit from a thoughtfully designed defined contribution plan and those left behind.

You provide a thoughtfully designed defined contribution plan, with a carefully selected default option designed to encourage savings, create diversification and help build retirement security. But this offering may not be reaching everybody. 

Reenrollment can get your participant population aligned with your current retirement plan best practices. Here are a few common scenarios that have spurred plans to consider reenrollment:

  • The new target date fund is the default investment option for new hires only, raising fiduciary concerns that legacy populations may not be in age-appropriate investments or sufficiently diversified.
  • Despite offering a diversified menu, participant data analytics reveal concentrations of inappropriate risk, insufficient savings rates or potentially inadequate retirement outcomes.
  • Following a merger or acquisition, executive leadership wants to combine all employees into a single plan or create a common experience across the workforce.
  • Participant communications about the new qualified default investment alternative (QDIA) have not driven legacy populations to switch to the new default.

It’s more common than you think

Most plan sponsors are aware of the benefits of reenrollment. In 2023, the World Investment Advisors reported that 55% of plan sponsors had considered reenrollment, and 26% had already conducted or planned to conduct in the next 18 months1.

Help participants help themselves

Very few participants may have the expertise, time and specialized insight needed to manage their own asset allocation. Even those who feel confident enough to make their own investment decisions may not review or adjust their investments over time and may no longer have an age-appropriate risk exposure. 

Reenrollment can help address these issues, and may even take advantage of participant inertia by automating the investment management they may need to reach their retirement goals. By reenrolling employees who aren’t currently invested in the QDIA, you can provide the same target date fund perks to all your participants, no matter when they joined the plan – ensuring that everyone may benefit.
