Pooled Employer Plans (PEPs) promise scale, simplicity, and cost efficiency for employers seeking to offer retirement benefits without shouldering the full complexity of plan administration. Yet with their advantages comes a nuanced question: what does co-fiduciary liability look like in a PEP structure? Understanding who is responsible for what—across the pooled plan provider (PPP), adopting employers, recordkeepers, investment managers, and other service providers—is essential to safeguarding participants and minimizing risk.
This article unpacks co-fiduciary liability in PEPs, highlights where responsibilities converge or diverge, and offers practical considerations for employers evaluating this model.
PEPs at a glance: who does what
- Pooled Plan Provider (PPP): The PPP serves as the named fiduciary and plan administrator for the PEP. It generally centralizes administration, vendor coordination, and oversight. Adopting employer: The employer that joins the PEP, retaining certain fiduciary duties—most notably, prudent selection and ongoing monitoring of the PEP and its PPP. Service providers: Recordkeepers, custodians, investment managers, auditors, and ERISA 3(38) or 3(21) fiduciaries deliver services under contract, bearing fiduciary responsibility where they exercise discretion or give fiduciary advice.
Even with the PPP’s elevated role, adopting employers do not fully escape fiduciary duties. Instead, their liability shifts from day-to-day plan operations to higher-order oversight, performance monitoring, and reasonableness of fees.
Clarifying co-fiduciary liability in PEPs The central issue is not whether liability disappears—it does not—but how it is shared and limited by contract and law.
- Fiduciary responsibility clarity: Employers should seek documents that precisely define which party assumes discretionary authority for investments, operations, and compliance. The clearer the delineation, the more reliable the liability pathway. Service provider accountability: Contracts should impose enforceable standards and measurable service-level expectations on PPPs and downstream vendors, including audit rights and remediation timelines. Shared plan governance risks: Even when fiduciary roles are well-documented, real-world governance can blur lines, particularly during exceptions handling (e.g., payroll errors, eligibility disputes). Build escalation protocols to prevent gaps.
Plan customization limitations PEPs are designed for standardization. That structure streamlines administration and cuts costs, but it often narrows plan design flexibility.
- Employers may find Plan customization limitations around eligibility, auto-enrollment parameters, employer match formulas, or vesting schedules. If your workforce strategy relies on highly tailored design elements, verify whether the PEP’s adoption agreement and optional provisions meet those needs. Weigh reduced flexibility against administrative relief—the trade-off is central to PEP suitability.
Investment menu restrictions A common feature of PEPs is a unified investment https://pep-shared-plan-model-hr-integration-guide.timeforchangecounselling.com/benchmarking-a-pep-metrics-kpis-and-success-measures lineup across participating employers, often overseen by a 3(38) investment manager engaged by the PPP.
- Investment menu restrictions can enhance fiduciary protection by centralizing selection and monitoring under a specialist. However, employers seeking bespoke white-label funds or custom target date series may encounter constraints. Confirm who holds discretion, how performance and fees are evaluated, and what triggers investment changes.
Vendor dependency and operational resilience PEPs hinge on a tightly integrated vendor stack: recordkeeping, custody, trading, advice, and compliance. This creates both efficiency and concentration risk.
- Vendor dependency increases the importance of service provider accountability—particularly in data integrity, payroll connectivity, cybersecurity, and distributions. Ensure your PPP maintains robust third-party risk management: SOC reports, cybersecurity certifications, incident response plans, and business continuity testing. Review how participant data flows and who remediates errors. Ask for evidence of operational audits and error correction policies.
Participation rules and workforce impact Another hallmark of PEPs is standardized eligibility and contribution parameters, though some allow limited flexibility.
- Participation rules matter for workforce planning. If you rely on eligibility waiting periods, union carve-outs, or different compensation definitions, confirm they are supported. Consider how standardized rules affect part-time, seasonal, or rehired employees. Clear mapping of HRIS and payroll fields reduces errors and fiduciary exposure.
Loss of administrative control: relief or risk? Many employers join PEPs to reduce administrative burdens. The trade-off is less hands-on control.
- Loss of administrative control is not inherently negative. It can reduce operational missteps, provided the PPP’s processes are sound and transparent. Require dashboards and reporting that allow you to monitor contributions, loan activity, distributions, and error corrections. Establish an internal governance calendar to review performance, fees, and participant outcomes at least annually.
Compliance oversight issues Regulatory compliance remains a shared responsibility, even in a PEP.
- The PPP typically handles annual filing, audit coordination, ERISA disclosures, and operational testing. Still, compliance oversight issues can arise if payroll data is inaccurate or late. Employers should implement controls over contributions timing, census accuracy, and eligibility determinations. The PPP can only validate what it receives. Align on error correction frameworks (e.g., EPCRS) and define who pays for corrective contributions, penalties, or fees.
Plan migration considerations Joining or leaving a PEP requires careful sequencing.
- Evaluate plan migration considerations such as asset mapping, blackout periods, stable value or guaranteed products with market value adjustments, and recordkeeping system compatibility. Confirm how legacy loans, QDROs, or corrective distributions will be handled. On exit, understand your options: spinning off into a standalone plan or transitioning to another PEP, and which party manages data, notices, and participant communications.
Practical steps to manage co-fiduciary liability
- Define roles in writing: Adoption agreements, service contracts, and fiduciary charters should explicitly allocate discretion and reporting. Document prudent process: Minutes, evaluations, and fee benchmarking evidence your oversight of the PPP and providers. Calibrate monitoring: Quarterly dashboards for service levels, error rates, investment performance, and participant outcomes keep you informed without recreating full plan administration. Benchmark fees and services: Compare all-in costs—recordkeeping, advisory, investment expenses—against market surveys and RFP results. Stress test operations: Walk through contribution uploads, eligibility determinations, loan processing, and distribution controls with the PPP. Escalation and indemnification: Ensure clear escalation paths, indemnities for provider negligence, and insurance coverage (e.g., fiduciary liability, cyber). Participant communication: Validate that notices are timely and comprehensible, and that call center metrics meet service standards.
Where liability starts and stops
- Adopting employers: Retain duty to prudently select and monitor the PEP, PPP, and key providers; ensure fees are reasonable; oversee payroll and data accuracy. PPP and 3(38) fiduciaries: Bear responsibility for investment selection and monitoring, plan operations, and vendor coordination as assigned. Recordkeepers and custodians: Responsible for accuracy and controls within their scope; fiduciary only if exercising discretion. Co-fiduciary liability: If an adopting employer knows of another fiduciary’s breach and enables it, fails to remedy it, or participates in it, liability can attach. Active monitoring and documented escalation help mitigate this risk.
Bottom line PEPs can materially reduce administrative friction and concentrate fiduciary duties with specialized providers. But they do not eliminate fiduciary responsibility. The best protection is clarity: define roles, demand measurable accountability, and maintain a disciplined oversight process. For many employers, that combination delivers better participant outcomes with manageable risk.
Questions and answers
Q1: Does joining a PEP eliminate my fiduciary liability? A1: No. It shifts your liability. You remain responsible for prudently selecting and monitoring the PEP, PPP, and core vendors, ensuring fees are reasonable, and maintaining accurate payroll and census data.
Q2: Can I customize plan design within a PEP? A2: Often only within defined parameters. Plan customization limitations are common to preserve uniform operations. Confirm allowable elections in the adoption agreement before joining.
Q3: Who decides the investment lineup? A3: Typically a PPP-appointed 3(38) fiduciary manages the lineup. This can create investment menu restrictions but centralizes accountability and monitoring.
Q4: What operational risks should I watch? A4: Vendor dependency, shared plan governance risks, and compliance oversight issues. Ask for SOC reports, service-level metrics, and incident response plans, and review them regularly.
Q5: What should I plan for when moving into or out of a PEP? A5: Focus on plan migration considerations—asset mapping, data quality, blackout periods, and handling of loans or special assets. Clarify each party’s duties and timelines in writing.
