Natixis Prevails in Complex ERISA Fiduciary Duty Case

ERISA Class Action | U.S. District Court for the District of Massachusetts

Following a two-week bench trial in the U.S. District Court for the District of Massachusetts, Judge Leo T. Sorokin ruled in favor of Natixis and its Retirement Committee on all counts. The lawsuit alleged that the committee improperly loaded the company’s 401(k) plan with proprietary Natixis funds that were more expensive and worse-performing than available alternatives. But after hearing evidence and witness testimony, the Court concluded that the plaintiffs failed to present proof that Natixis or its committee acted disloyally, prioritized corporate interests, or engaged in the kind of imprudent oversight necessary to establish a fiduciary breach.

In a detailed written ruling, Judge Sorokin found that, while the committee was not “procedurally perfect,” its actions did not amount to actionable lapses. The Court credited evidence showing that the committee used a third-party investment consultant, regularly received and reviewed quarterly performance reports, and selected proprietary funds only when they were the highest-performing finalists under consideration. The judge rejected the idea that the plan was “plagued” by mismanagement and noted that even the committee’s admitted shortcomings did not result in measurable losses for participants, nor did they reflect disloyal or self-serving motives. As the Court observed, the record reflected a fiduciary body that was engaged, informed, and consistently updating the plan lineup, not one attempting to “sneak” proprietary funds into the plan at employees’ expense.

DOAR supported the defense throughout the proceedings, providing demonstrative development and courtroom evidence presentation to clearly explain complex investment decision-making processes and fiduciary oversight practices.

Demonstrating Prudent Oversight and Fiduciary Integrity

The visual exhibits developed by DOAR effectively demonstrated the diligence, transparency, and informed decision-making underlying Natixis’s retirement plan management. The graphics summarized key documentation, survey data, and procedural evidence to show that the Retirement Committee acted prudently and in the best interests of plan participants.

Through clear timelines, participant data visualizations, and process diagrams, the exhibits illustrated that investors who made independent allocation choices were financially informed, and that the Committee followed a structured, consultative process—supported by independent research and professional oversight—when evaluating and selecting investment options. Collectively, these visuals helped the Court see that the plan’s administration was methodical, compliant, and grounded in sound fiduciary judgment, supporting the ruling in favor of Natixis and its Retirement Committee.
