Background

Quest Diagnostics offered its employees a 401(k) defined-contribution retirement plan that included a menu of investment options managed by an Investment Committee. The Committee hired outside investment advisors — first Mercer Investment Consulting, then AON — met quarterly, and prepared Investment Policy Statements governing how funds would be evaluated, added, or removed. Two options on the menu drew scrutiny: the Fidelity Freedom Funds, a suite of actively managed target-date funds, and the Invesco Global Real Estate Fund, an actively managed mutual fund concentrated in real estate investment trusts.

A class of plan participants filed suit under ERISA, alleging that the Committee breached its fiduciary duty of prudence by retaining the Freedom Funds and the Invesco Fund despite underperformance against benchmarks. Plaintiffs argued the Freedom Funds were riskier than disclosed due to a 2014 glide-path change that increased equity exposure, and that both funds ranked in the bottom half of comparable funds during material periods. They also contended the Committee’s own Investment Policy Statements obligated it to remove the funds. The complaint asserted three counts: breach of the duty of prudence under 29 U.S.C. § 1104(a), failure to monitor under §§ 1105(a) and 1109(a), and knowing breach of trust as an alternative if any defendant were found not to be a fiduciary.

The U.S. District Court for the District of New Jersey (Judge Neals) denied Quest’s motion to dismiss but granted summary judgment after discovery, finding no breach of fiduciary duty. Plaintiffs appealed.

The Court’s Holding

The Third Circuit, in an opinion by Judge Bibas joined by Judges Porter and Bove, affirmed summary judgment for Quest on all three counts. The court held that ERISA’s prudence standard is primarily a process-based inquiry, and that Quest’s Investment Committee followed a sound process: it hired and critically engaged with outside advisors, met regularly with the managers of the challenged funds, considered alternatives, and revised the plan menu on multiple occasions. That prudent process defeated the breach-of-duty claim at the first step of the court’s two-step framework, without any need to assess whether a hypothetical prudent investor would have reached the same outcome.

On the policy-statement theory, the court declined to decide whether Investment Policy Statements are binding plan documents under § 1104(a)(1)(D), finding it unnecessary because Quest’s statements used permissive language throughout — the Committee “may” remove funds, and “[n]o single factor” was dispositive. Drawing on trust-law principles, the court held that where a fiduciary is granted discretion, a court’s role is only to prevent an abuse of that discretion, and no abuse occurred here. The court also rejected plaintiffs’ expert report because it rested on the legally incorrect premise that short-term underperformance alone mandated removal.

Because no breach of the duty of prudence was established, the failure-to-monitor claim (Count Two) and the knowing-breach-of-trust fallback claim (Count Three) necessarily failed as well, and the court affirmed summary judgment across the board.

Key Takeaways

  • ERISA prudence is process-first: a fiduciary that hires an advisor, critically examines recommendations and underlying data, meets with fund managers, and monitors the menu over time satisfies its duty even if some retained funds produce subpar returns.
  • Short-term underperformance — even ranking in the bottom half of peer funds for one to two years — does not by itself prove imprudence, particularly for long-horizon target-date funds where modest underperformance may reflect a deliberate and defensible investment strategy.
  • Actively managed funds and passive index funds are not interchangeable benchmarks; comparing the two to show imprudence is an “apples and oranges” argument the Third Circuit (following the Sixth and Eighth Circuits) rejects.
  • Investment Policy Statements drafted in permissive terms (“may” place on watch list, no single factor dispositive) do not bind fiduciaries to remove underperforming funds; courts defer to fiduciary judgment absent an abuse of discretion.
  • Derivative ERISA claims for failure to monitor and knowing breach of trust rise and fall with the underlying prudence claim.

Why It Matters

This decision reinforces a process-centered, deferential standard for ERISA 401(k) fiduciaries that has been gaining traction across circuits in the wake of Hughes v. Northwestern University (2022). Plan sponsors and investment committees can draw comfort from the ruling’s clear message that retaining a below-average fund is not a per se breach so long as the committee engaged in genuine, documented analysis — hiring advisors, interrogating their data, meeting with fund managers, and revisiting decisions over time. The opinion also provides practical guidance on how to draft Investment Policy Statements: permissive language preserves fiduciary discretion and shields plans from arguments that internal governance documents created enforceable removal obligations.

For plaintiffs’ counsel, the decision narrows the evidentiary path in ERISA prudence cases. Expert opinions that simply restate the underperformance narrative without addressing the fiduciary’s actual reasoning — including the specific investment rationale the committee articulated for retaining a fund — will not survive summary judgment. The court’s skepticism of short-term benchmark comparisons and its explicit rejection of active-versus-passive apples-to-oranges arguments align the Third Circuit squarely with the Sixth and Eighth Circuits, signaling that ERISA excessive-fee and imprudence litigation faces a high bar at the summary-judgment stage.
