ERISA Prudence in the Third Circuit: A Prudent Monitoring Process Defeats Underperformance Claims at Summary Judgment

I. Introduction

Lawanda Lasha House Johnson, et al. v. Quest Diagnostics Inc., et al. arises from a challenge by participants in Quest Diagnostics’ 401(k) plan to two plan investment options: (1) the Fidelity Freedom Funds (actively managed target-date funds) and (2) the Invesco Global Real Estate Fund (an actively managed real-estate-oriented mutual fund). Plaintiffs alleged that continuing to offer these options violated fiduciary duties under the Employee Retirement Income Security Act (ERISA), principally ERISA’s duty of prudence, and asserted related monitoring and “knowing breach of trust” theories.

The central issues were process-centered: whether Quest’s fiduciaries acted prudently in monitoring and retaining the challenged options, and whether alleged benchmark underperformance (and plan “Investment Policy Statements”) required removal of the funds. The Third Circuit, affirming summary judgment for Quest, framed the case as a “process, not outcomes” dispute: even “disappointing results” do not establish liability where the fiduciary’s monitoring and decisionmaking process was sound.

II. Summary of the Opinion

The Third Circuit affirmed the District Court’s grant of summary judgment to Quest. It held that plaintiffs’ imprudence theory failed at step one of the circuit’s framework: Quest’s fiduciaries employed a prudent process in evaluating, monitoring, and deciding to retain the Freedom Funds and the Invesco Fund. Key process facts included quarterly Investment Committee meetings, annual fiduciary training, retaining outside investment advisors (Mercer and AON), preparing Investment Policy Statements, meeting with fund managers, requesting comparative analyses, and using a watch-list practice for concerns.

The court rejected plaintiffs’ effort to convert periods of underperformance into a de facto rule requiring fund removal, and it declined to treat the Investment Policy Statements as mandating any particular outcome—especially given their permissive, non-dispositive language. Because there was no underlying prudence breach, plaintiffs’ monitoring and fallback claims also failed.

III. Analysis

A. Precedents Cited (and How They Shaped the Decision)

1. Supreme Court foundations: trust-law roots, continuing duty, and context-specific prudence

  • Tibble v. Edison Int'l, 575 U.S. 523 (2015): The court used Tibble for two pivotal propositions: (i) ERISA fiduciary standards are “derived from the common law of trusts,” and (ii) fiduciaries have a “continuing duty to monitor” investments and remove imprudent ones. The panel treated monitoring as ongoing, but emphasized that “monitor” does not mean “react mechanically to short-term performance.”
  • Hughes v. Nw. Univ., 595 U.S. 170 (2022): The court relied on Hughes to reject categorical rules and to insist on “context specific” evaluation with “due regard” for the “range of reasonable judgments” available to experienced fiduciaries. This underwrote the opinion’s core move: plaintiffs’ performance-based heuristics could not substitute for a process analysis.

2. Third Circuit framework: process first, then (only if needed) hypothetical prudent investor

  • Renfro v. Unisys Corp., 671 F.3d 314 (3d Cir. 2011): The court treated Renfro as establishing a two-step structure: (1) if the fiduciary’s process was prudent, the inquiry ends; (2) only if the process was imprudent does the court ask whether a “hypothetical prudent investor” would have made the same decision anyway. Here, plaintiffs lost at step one.
  • Sweda v. Univ. of Pa., 923 F.3d 320 (3d Cir. 2019), abrogated in part by Hughes v. Nw. Univ., 595 U.S. 170 (2022): The court cited Sweda for the principle that prudence is “largely a process-based inquiry,” while acknowledging Hughes altered aspects of Sweda. Functionally, Sweda supports the panel’s emphasis that outcomes alone are not dispositive.

3. Third Circuit’s summary-judgment prudence touchstone: independent investigation and informed reliance

  • In re Unisys Sav. Plan Litig., 74 F.3d 420 (3d Cir. 1996): This opinion is the workhorse precedent. The panel extracted from Unisys the requirement that fiduciaries “conduct an independent investigation,” which includes reviewing consultant data, assessing its significance, and supplementing it when needed. The court also used Unisys to warn that fiduciaries may not “reflexively rely” on advisors; reliance must be “justified” and “informed.”

    Applying Unisys, the court organized its evaluation around three practical questions: (i) whether Quest reviewed and supplemented advisor data, (ii) whether Quest understood the bases and methodology of advisor recommendations, and (iii) whether Quest otherwise followed reasonable practices. Finding “yes” across the board, the court distinguished the “uninformed” or “memoryless” fiduciaries in Unisys from a committee that had contemporaneous reports, meetings, comparisons, and watch lists.

4. Comparative-investment pleading vs. proof: “apples and oranges” and time-horizon discipline

  • Smith v. CommonSpirit Health, 37 F.4th 1160 (6th Cir. 2022): The panel adopted Smith’s reasoning that actively managed funds and passive index funds may be “apples and oranges,” reflecting different strategies and thus often not meaningful comparators for imprudence. It used this to explain why plaintiffs’ initial passive-comparator theory failed (and was abandoned).
  • Meiners v. Wells Fargo & Co., 898 F.3d 820 (8th Cir. 2018): Cited alongside Smith to reinforce that different investment strategies are not fungible, supporting skepticism of simplistic “cheaper/passive did better” comparisons.
  • Pizarro v. Home Depot, Inc., 111 F.4th 1165 (11th Cir. 2024): Quoted to fortify the time-horizon point: a “five-year snapshot” may not demonstrate imprudence for investments designed to play out over decades. This supported the court’s rejection of plaintiffs’ short-term underperformance narrative.

5. Standards for defeating summary judgment and dealing with expert opinions

  • Tundo v. County of Passaic, 923 F.3d 283 (3d Cir. 2019): Provided the de novo standard of review and the requirement to view evidence in plaintiffs’ favor on appeal.
  • Anderson v. Liberty Lobby, Inc., 477 U.S. 242 (1986): Used to dismiss a “scintilla” of evidence (an isolated email) as insufficient to create a genuine dispute of material fact on prudence.
  • Brooke Grp. Ltd. v. Brown & Williamson Tobacco Corp., 509 U.S. 209 (1993): Cited for the proposition that an expert report resting on a legally flawed premise cannot defeat summary judgment. The panel applied this to plaintiffs’ expert (Driscoll), whose “remove upon short-term underperformance” approach conflicted with the court’s understanding of ERISA prudence.

6. Policy statements, discretion, and trust-law deference

  • Cal. Ironworkers Field Pension Tr. v. Loomis Sayles & Co., 259 F.3d 1036 (9th Cir. 2001) and Dardaganis v. Grace Cap. Inc., 889 F.2d 1237 (2d Cir. 1989): Plaintiffs invoked these to argue that investment guidelines/IPS violations can be actionable under ERISA. The Third Circuit treated Cal. Ironworkers as not deciding the issue (because it found no guideline violation), and it did not adopt any Second Circuit-style rule.
  • Tussey v. ABB, Inc., 746 F.3d 327 (8th Cir. 2014): Used to show that other circuits doubt whether IPS documents are binding plan “documents and instruments” for ERISA § 1104(a)(1)(D) purposes.
  • Firestone Tire & Rubber Co. v. Bruch, 489 U.S. 101 (1989): Though a benefits case, it supplied the trust-law rationale for deference when discretion is conferred: courts intervene only to prevent an “abuse” of discretion.

7. Waiver and “footnote” arguments

  • In re: Asbestos Prods. Liab. Litig. (No. VI), 873 F.3d 232 (3d Cir. 2017): Cited for the rule that arguments raised only in a footnote are forfeited, supporting the court’s refusal to address plaintiffs’ Department of Labor guidance discussion.

8. Derivative monitoring liability

  • Mator v. Wesco Distrib., Inc., 102 F.4th 172 (3d Cir. 2024): Used to conclude that without an underlying breach of prudence, a failure-to-monitor claim cannot survive.

9. Restatements as trust-law background

  • Restatement (Third) of Trusts § 93, cmt. c (2012): Cited to treat professional advice as significant evidence of prudence, not a complete defense.
  • Restatement (Third) of Trusts § 91, cmt. f (2007) and Restatement (Second) of Trusts § 187 (1959): Cited to support the proposition that permissive investment provisions do not create mandatory duties and that discretionary choices are reviewable only for abuse.

B. Legal Reasoning

1. The core holding: ERISA prudence is predominantly process-based

The opinion’s throughline is that ERISA’s duty of prudence (29 U.S.C. § 1104(a)(1)(B)) is assessed by evaluating the fiduciary’s decisionmaking process “under the circumstances then prevailing,” not by “disappointing results” alone. The court emphasized that fiduciaries need not have “crystal balls,” and that underperformance—especially short-term or non-egregious underperformance—does not mandate “drastic or sudden action.”

2. A structured application of Unisys to the record

The panel effectively operationalized In re Unisys Sav. Plan Litig. into three evaluative considerations:

  1. Review and supplementation of advisor data: Quest’s committee met quarterly, obtained fiduciary training, engaged Mercer, commissioned comparative analyses (including a 2016 and 2019 reanalysis of target-date options), met with Fidelity about the Freedom Funds, put the Invesco Fund on a watch list, met with Invesco, and considered alternatives.
  2. Understanding the basis for recommendations: The committee’s documented rationale mattered. For the Freedom Funds, it understood the glide-path change and why “through-retirement” design fit participant behavior (participants tended to keep assets in the plan after retirement), mitigating sequence-of-returns risk. For the Invesco Fund, it understood the “downside protection” tradeoff: more conservative positioning can lag in bull markets yet serve a risk-management role in a diversified lineup.
  3. Reasonableness of overall governance practices: The committee’s history of lineup adjustments (replacing funds, changing money-market funds, watch lists, and multiple fund replacements) supported an inference of active monitoring rather than neglect.

This structure allowed the court to conclude that plaintiffs’ evidence (including one negative email and an expert report premised on short-term returns) could not create a triable issue of process imprudence.

3. Rejecting a performance-trigger “removal” rule

The court declined to transform benchmark underperformance into an automatic duty to remove funds. It reasoned that: (i) a below-median ranking in limited windows does not establish that an investment was imprudent for a long-term retirement vehicle; (ii) requiring removal of “every below-average fund would create chaos”; and (iii) ERISA does not require selecting the “best” option, only a prudent process for selecting and monitoring reasonable options.

4. Comparators and strategy differences: active vs. passive

Consistent with Smith v. CommonSpirit Health and Meiners v. Wells Fargo & Co., the court treated active and passive strategies as materially different. This matters doctrinally because many ERISA imprudence cases turn on what is a valid benchmark or comparator: a strategy mismatch can make a performance comparison probatively weak, even if superficially appealing.

5. Investment Policy Statements: even assuming applicability, permissive language preserved discretion

Plaintiffs attempted an alternate route through ERISA § 1104(a)(1)(D), which requires fiduciaries to follow plan-governing documents insofar as consistent with ERISA. The court avoided definitively deciding whether Investment Policy Statements qualify as “documents and instruments governing the plan” in this circuit. Instead, it held that even if they were covered, Quest did not violate them because they were explicitly non-mandatory: the committee “may” take actions; “no single factor” was dispositive. Trust-law deference to discretionary judgment (anchored in Firestone Tire & Rubber Co. v. Bruch) reinforced that courts should not second-guess these choices absent abuse of discretion—which the record did not show.

6. Cleanup holdings: forfeiture and derivative claims

The court treated two peripheral points as waived/insufficiently presented (default-investment scrutiny and Department of Labor guidance) under In re: Asbestos Prods. Liab. Litig. (No. VI). It then disposed of the monitoring and knowing-breach counts because they depended on an underlying prudence breach, relying on Mator v. Wesco Distrib., Inc..

C. Impact

1. A clearer Third Circuit pathway to summary judgment in investment-underperformance cases

The decision strengthens defendants’ ability to win at summary judgment where they can demonstrate an organized monitoring record: regular committee meetings, documented review of consultant reports, targeted follow-up (including meetings with fund managers), comparative analyses, and watch-list use. The opinion signals that plaintiffs will need more than returns-based narratives; they must create a genuine factual dispute about the prudence of the process.

2. Underperformance alone is insufficient; “severe and sustained” is suggested as the outer boundary

The panel did not define a numeric threshold, but it indicated that only underperformance that is “severe and sustained enough” could potentially support an inference of process imprudence by itself. Practically, this raises the evidentiary burden in performance-only cases and encourages litigants to focus on governance failures (missing meetings, absent documentation, ignoring red flags, failure to investigate) rather than outcomes.

3. Litigation over Investment Policy Statements is likely to shift to language and discretion

By sidestepping whether IPS documents are binding under § 1104(a)(1)(D), while holding permissive IPS language defeats “mandatory removal” claims, the decision pushes future disputes toward contract-like textual analysis: “may” vs. “shall,” non-dispositive-factor clauses, and discretion-preserving provisions. Plan sponsors may respond by drafting IPS documents with clearer discretionary terms, mindful that rigid language could be argued to create enforceable constraints.

4. Comparator discipline: active/passive and strategy-aligned benchmarks

The court’s endorsement of “apples and oranges” reasoning discourages simplistic comparisons between active funds and passive index alternatives, especially for target-date products where glide-path design and through-retirement assumptions materially affect risk and return. Plaintiffs will be pressed to identify strategy-consistent comparators and to explain why differences do not matter.

5. “Default investment” theories remain open but must be properly developed

The court did not reach whether default-status heightens scrutiny because plaintiffs did not properly present it. Future litigants may still pursue default-investment prudence theories, but this opinion warns that courts will enforce waiver rules and require fully developed briefing rather than passing references.

IV. Complex Concepts Simplified

  • Defined-contribution plan (401(k)): Participants choose from a menu of investments; retirement outcomes depend on contributions and investment performance (not a guaranteed benefit).
  • ERISA fiduciary duty of prudence (29 U.S.C. § 1104(a)(1)(B)): A fiduciary must act with the care, skill, prudence, and diligence of a knowledgeable person in similar circumstances. Courts primarily examine the decisionmaking process used.
  • “Process, not outcomes”: A fund can underperform and yet a fiduciary may be prudent if it monitored appropriately, understood the strategy, investigated concerns, and made a reasonable judgment.
  • Target-date fund: A diversified fund keyed to an expected retirement year; it adjusts its mix over time.
  • Glide path: The schedule of how a target-date fund shifts from stocks to more conservative assets over time.
  • “Through-retirement” vs. “to-retirement”: Through-retirement funds assume participants remain invested after retiring, often staying more growth-oriented for longer; to-retirement funds may de-risk more by the retirement date.
  • Active vs. passive management: Active managers select securities to beat a benchmark; passive funds track an index. Different strategies can justify different expectations and comparisons.
  • Watch list: A governance tool where a committee flags an investment for heightened review rather than immediate removal.
  • Summary judgment: A court may decide a case without trial if no genuine dispute of material fact exists and the movant is entitled to judgment as a matter of law.
  • ERISA § 1104(a)(1)(D): Requires fiduciaries to follow plan-governing documents if consistent with ERISA; the dispute here was whether Investment Policy Statements are binding, and how permissive language affects that analysis.

V. Conclusion

The Third Circuit’s decision reinforces a pragmatic ERISA principle: fiduciary prudence is judged primarily by the quality of the monitoring and decisionmaking process, not by whether every investment outperforms or whether hindsight reveals a better choice. Applying trust-law-informed standards from Tibble v. Edison Int'l, Hughes v. Nw. Univ., and especially In re Unisys Sav. Plan Litig., the court held that Quest’s committee acted prudently by engaging expert advisors, reviewing and understanding the bases for recommendations, following up with fund managers, using governance tools like watch lists, and documenting a pattern of active lineup management.

The broader significance is twofold: (1) plaintiffs alleging imprudence based on underperformance must squarely attack process with concrete evidence, and (2) Investment Policy Statements—particularly those written in permissive, non-dispositive terms—will not easily be converted into rigid, court-enforced mandates. In the Third Circuit, ERISA continues to demand prudence, not perfection.
