Department of Labor Proposes New Regulatory Safe Harbor for Prudent Selection of Designated Investment Alternatives in Participant-Directed Individual Account Plans

Why It Matters

The safe harbor could lower litigation risk and costs for plan fiduciaries, potentially expanding the range of investment choices available to retirement participants. However, its effectiveness depends on judicial acceptance and the ability to meet stringent liquidity and valuation standards for alternatives.

Key Takeaways

• DOL proposes safe harbor for DIA selection under ERISA
• Fiduciaries get presumption of prudence if six factors documented
• Liquidity and valuation pose biggest challenges for alternative‑investment DIAs
• Legal weight uncertain after Supreme Court limits agency deference
• Comment period ends June 1, 2026; final rule could reshape plan offerings

Pulse Analysis

The Department of Labor’s March 30 proposal seeks to codify a safe harbor that would shield plan fiduciaries from liability when they follow a structured, analytical process for choosing designated investment alternatives (DIAs). By requiring documentation of six core factors—performance, fees, liquidity, valuation, benchmarking and complexity—the rule aims to create a legal presumption of prudence, reducing the defensive costs associated with ERISA litigation. This move aligns with the administration’s broader push to broaden retirement plan investment options, especially alternative assets that have traditionally faced scrutiny for illiquidity and opaque valuation.

Practically, the safe harbor presents both opportunity and hurdle for plan sponsors. Traditional mutual funds and ETFs can readily satisfy the liquidity and valuation criteria, but many alternative‑investment DIAs, such as private‑equity or closed‑end funds, struggle with the required transparency and redemption flexibility. Fiduciaries will likely adopt a cautious, incremental approach, integrating alternatives primarily through professionally managed pooled vehicles or target‑date funds where expertise and risk‑adjusted returns can be demonstrated. The documentation burden may also drive greater reliance on investment‑advice fiduciaries to navigate complex fee structures and benchmark selection.

The proposal’s ultimate impact hinges on judicial interpretation. Recent Supreme Court rulings, notably Loper Bright Enterprises v. Raimondo, have curtailed deference to agency interpretations absent clear congressional direction, casting doubt on whether courts will grant the proposed presumption of prudence any substantive weight. Until the DOL’s rule is finalized and survives potential legal challenges, plan sponsors must balance the allure of expanded investment choices against the risk of heightened scrutiny. The June 1, 2026 comment deadline offers stakeholders a chance to shape the final language, but even a favorable outcome may only modestly shift the landscape for alternative‑investment DIAs.
