The plaintiffs also accuse the plan and its administrative and investment committees of allowing its recordkeeper to receive fees from an agreement with Financial Engines to provide participants with investment advice. Other lawsuits have challenged fees paid to recordkeepers from arrangements with Financial Engines. However, unlike the Northrop Grumman complaint, these lawsuits were filed against the recordkeepers and not the plan sponsors. In two cases—a lawsuit against Xerox HR Solutions and a lawsuit against Voya Financial —a federal judge dismissed the claims, saying the plan sponsor was the fiduciary responsible for negotiating fees for plan providers.
