A participant in Rockland Trust's 401(k) plan has filed a lawsuit accusing the plan of poor fund performance, according to a Bloomberg Law report — the kind of retirement-plan fee and performance case that has increasingly forced HR and benefits leaders to re-examine how their plan's investment menu is built and monitored.

The suit, filed by a plan investor, centers on the performance of funds offered within the company's retirement plan. Cases of this type typically allege that fiduciaries kept underperforming or costly investment options on the menu when better-performing, cheaper alternatives were available — a claim that goes to the heart of the committee-level decisions employers make about fund selection, retention and benchmarking.

What does the suit mean for plan fiduciaries?

For HR and total-rewards teams at Rockland Trust and beyond, the litigation underscores the legal exposure attached to the investment-committee function. Named fiduciaries — often senior HR, finance and legal executives — carry the burden of showing a prudent process for choosing and retaining plan funds, not merely defensible outcomes.

That process typically involves:

• Regular benchmarking of fund performance against relevant indices and peer groups
• Documentation of investment-committee deliberations and rationales
• Periodic RFPs or fee reviews covering recordkeeping and management costs
• Removal or watchlist decisions for funds that trail peers over defined periods

Why fund-performance suits keep coming

Litigation over 401(k) investment menus has become a durable feature of the employee-benefits enforcement environment. Plaintiffs' firms routinely screen plan Form 5500 filings and fund data to identify menus with underperforming or higher-cost options, using that analysis to frame fiduciary-breach claims under the Employee Retirement Income Security Act.

For employers, the practical consequence is procedural: committees that cannot produce records of a disciplined monitoring process face harder settlement dynamics than those that can. Bloomberg Law's report on the new filing signals that mid-sized and regional employers — not just large national plan sponsors — remain squarely in plaintiffs' counsel's sights.

The Rockland Trust case will now move through pleadings, where the employer can be expected to challenge whether the participant's allegations state a plausible fiduciary breach; HR teams at similarly sized sponsors will be watching whether the court lets the fund-performance theory proceed.
