Multiemployer Pension Plan Withdrawal Overview
Multiemployer pension plans in the United States generally cover unionized participants from more than one participating employer. When an employer discontinues participation—or withdraws—from a plan, the employer stops making regular contributions and is generally assessed a
withdrawal liability, which is typically paid over time. Because of a variety of statutory and practical limitations, the withdrawal liability actually paid may or may not be sufficient to cover any unfunded liabilities associated with the now-withdrawn employer.
The SOA has received questions as to the prevalence and impact of MEPP employer withdrawals. These articles by SOA staff actuaries Lisa Schilling and Patrick Wiese present analysis of employer withdrawals as reflected in data from Department of Labor Forms 5500.
