"[Plaintiffs claim] that UnitedHealth breached its fiduciary duties under ERISA when it used assets from the plaintiffs' plans to recoup financial losses from other separate plans, effectively using plaintiffs' plan assets for its own benefit.... [T]he plaintiffs assert that, 'By engaging in cross-plan offsetting, United treats the thousands of Plans it administers as one extremely large piggybank, moving more than $1.2 billion among its Plans each year to suit its own interests. Each cross-plan offset violates ERISA, and in most cases, the money ends up in United's own pocket.' " [Scott v. UnitedHealth Group, Inc., No. 20-1570 (D. Minn. complaint filed Jul. 14, 2020)]
