To versus through glide paths: what’s the difference?
As a plan sponsor of a retirement plan, staying up to date with the strategies that can help members navigate retirement risks, including the risk they face of outliving their savings due to longer lifespans, can be important. We can help you understand how target-date funds and different glide path designs can help your members achieve financial resilience.

This viewpoint is part of our latest analysis, “Analyzing the merits of through versus to glide paths,” which is designed to help guide your retirement planning decision-making.
Your role in helping members retire comfortably
One of the most significant changes in retirement planning has been the move from defined benefit pension plans to defined contribution plans. This transition has shifted much of the financial responsibility and risk from employers to employees, but there’s a general concern that individuals may not possess the investing expertise needed to navigate long-term financial stability. That’s where you step in. As a plan fiduciary, you play a pivotal role in selecting the plan’s default investment options, which many members may end up holding throughout the life of their plan.
Target-date funds are a viable option for the default investment selection because they offer a diversified and professionally managed strategy targeted toward a planned retirement date. How do you know which target-date fund is the right one for your plan?
To and through have different glide path designs
A glide path is the asset allocation over time within a target-date fund. It shows how and when the allocation changes to balance growth potential with risk management.
Each target-date fund has its own glide path design to manage risk differently. One of the key differences between to and through glide paths is that the to path becomes static during the decumulation phase, whereas the through path continues to invest using an accumulation strategy. Plan sponsors should consider your members’ demographics and assess how each glide path would address their needs.
