American Rescue Plan Act of 2021 Funding Relief for Single-Employer Pension Plans

ARPA 2021 provides funding relief for single-employer pension plans, related to interest rates used for minimum funding purposes.

Mar 17, 2021

Among many provisions in the American Rescue Plan Act (ARPA 2021) signed into law last week by President Biden, this legislation offers funding relief for single-employer defined benefit pension plans. ARPA 2021 includes several provisions related to the interest rates used for minimum funding purposes. Here is a review of current regulations and summary of some of the pertinent changes.

Summary of Current Regulations

Under prior regulations, the interest rate relief provided under the Bipartisan Budget Act of 2015 was scheduled to begin phasing out in 2021. In particular, the 10% corridor around the 25-year average of rates that has been in effect for several years, was set to expand to a 15% corridor in 2021 with further expansion in 2022 – 2024 at an additional 5% per year until reaching 30%. The graphical representation below shows the changes in interest rates that were expected to occur over the next several years as the corridor expanded, assuming rates remained at or near current levels.



American Rescue Plan Act (ARPA 2021) – Changes

The ARPA 2021 legislation provides for several changes related to the interest rates used for minimum funding purposes. First, ARPA 2021 includes an interest-rate floor of 5% on the 25-year average of rates. This provision alone means that a Plan’s effective interest rate will not fall below 3.50%. In addition to the interest-rate floor, the legislation provides for a revised corridor schedule. It will reduce the corridor to 5% with the ability to adopt it retroactive to 2020. This 5% corridor would remain in effect until the plan year beginning in 2025 and then increase by 5% per year until fully phased in at a 30% corridor for the plan year beginning in 2030. The following is a representation of the expected effects on our sample plan.



As you can see, the interest rate relief will have a profound effect on the rates used to determine minimum funding requirements, and implementation of the new rates will move plan funded percentages higher. Because the mandated interest rates affect minimum required contributions and benefit restrictions under IRC 436, the new law allows plan sponsors some flexibility regarding the timing of adoption for plan years beginning prior to January 1, 2022. In particular, it allows adoption either (1) for minimum funding purposes only, or (2) for both minimum funding purposes and for purposes of benefit restrictions depending on each sponsor’s particular circumstances.

The legislation also increases the time period over which any funding shortfalls may be paid. It expands the time period from 7 years under current law to 15 years. The combination of higher minimum funding interest rates and a longer amortization period over which to spread any underfunding comes as welcome relief to cash-strapped sponsors of single-employer defined benefit pension plans. In addition, the change in amortization periods is allowed, retroactively, to plan years beginning in 2019 for those plan sponsors who wish to elect it.
