The Multiemployer Health Plan Landscape:
A Ten-Year Look (2009-2018)

Benefit costs over the past decade have increased on average of 4.4% per year, according to the new report The Multiemployer Health Plan Landscape: A Ten-Year Look (2009-2018)

There has been a shift in the demographics of these plans since 2009—The number of covered retirees decreased by 3% while active participants  increased by 14%. Although the number of retirees has gone down over the last decade, because retired participants generally contribute less to plan assets than the cost of their benefits, a higher number of retirees can make it increasingly difficult for plan trustees to manage the financial shortfall for these retired participants. 

Despite the shift in demographics, the overall number of participants covered by multiemployer health plans has remained relatively unchanged over the past ten years, and the financial condition of many multiemployer health plans has improved.

This fifth annual multiemployer health plan benchmarking report was produced in partnership with Horizon Actuarial Services, LLC, and the International Foundation of Employee Benefit Plans.

The comprehensive report covers the plan demographics, benefit costs, income and plan cash flows of 1,500 multiemployer health plans—providing coverage for more than five million participants.

About the Survey:

The International Foundation of Employee Benefit Plans and Horizon Actuarial Services, LLC, have partnered to build a database of historical information for multiemployer benefit plans in the United States. A database of multiemployer defined benefit (DB) plans was originally developed during the summer of 2014 using publicly available information from Form 5500 filings. The database of multiemployer defined contribution (DC) plans followed in the summer of 2015 as a supplement to the original DB plan database. A separate report incorporating the results from these databases is available through the International Foundation website. The database of health plans, the subject of this report, was developed in the summer of 2017.
