Supreme Court Resolves Circuit Split on Timing for Selection of Actuarial Assumptions to Calculate Multiemployer Pension Withdrawal Liability
The United States Supreme Court recently held in M&K Employee Solutions, LLC et al. v. Trustees of the IAM National Pension Fund that the Employee Retirement Income Security Act of 1974 (“ERISA”) does not require that the actuarial assumptions used to calculate withdrawal liability be selected on or before the statutory measurement date. In doing so, the Court resolved a split between the Second and D.C. Circuits on when those assumptions may be selected. What is withdrawal liability? Withdrawal liability is the proportionate share of a multiemployer pension plan’s unfunded vested benefits owed by a contributing employer that partially or completely withdraws from the plan. A multiemployer pension plan is a plan to which more than one employer contributes and that is maintained pursuant to one or more collective bargaining agreements. ERISA requires employers that withdraw from an underfunded multiemployer pension plan to pay their share of the plan’s unfunded vested benefits
