"[A] federal district court in Utah has ruled that former participants are entitled to benefits under both their original plan and their new plan for the same period of service because they were not notified of the transfer of their benefits.... This is clearly a result that the parties never intended.... How can plan sponsors avoid it? ... [These] practices put sponsors in a position to respond effectively to double-dipping claimants:" [Anderson v. CEMEX, No. 2:12-00136 (D. Utah Dec. 29, 2014)]
