A federal court recently held that two investment funds are not jointly and severally liable for a bankrupt portfolio company’s withdrawal liability to a multiemployer pension plan disagreeing with a 2007 opinion by the Appeals Board of the Pension Benefit Guaranty Corporation (the “PBGC”). The Massachusetts U.S. District Court ruled there was no liability because the investment funds are not “trades or businesses” for purposes of ERISA’s joint and several liability rules.
