"If the Supreme Court sides with the Second Circuit, ... withdrawal liability estimates requested by and provided to employers prior to their withdrawal will be more reliable estimates of the actual withdrawal liability.... If, however, the court sides with the D.C. Circuit ... withdrawal liability estimates will be arguably unreliable for purposes of estimating the actual withdrawal liability, making it more difficult to plan for withdrawal liability in the same manner as an employer does any other corporate liability." [M&K Employee Solutions, LLC v. Trustees of the IAM National Pension Fund, No. 22-7157 (D.C. Cir Feb. 9, 2024; cert. pet. granted Jun. 30, 2025 No. 23-1209)]  MORE >>
