Key Takeaways
- • The U.S. Department of Labor issued a proposed rule on March 31, 2026, establishing a process-based safe harbor for fiduciaries selecting 401(k) designated investment alternatives (DIAs), with comment period closing June 1, 2026.
- • The Safe Harbor creates a six-factor framework—Performance, Fees, Liquidity, Valuation, Performance Benchmark, and Complexity—that, if "objectively, thoroughly and analytically" considered, presumes fiduciaries have met ERISA Section 404(a)(1)(B) duties and entitles them to significant deference.
- • The proposed rule addresses alternative assets (private equity, private credit, digital assets, cryptocurrency) but extends beyond them to cover all designated investment alternatives, broadening fiduciary guidance previously discouraging alternative inclusion in 401(k) menus.
- • The DOL provided 20 non-exhaustive examples within the proposed rule itself to demonstrate how fiduciaries should apply each of the six factors across specific factual circumstances, creating a practical implementation roadmap.
- • The rule represents a shift from outcome-based to process-based fiduciary evaluation, emphasizing the methodology and documentation of investment selection rather than requiring predictive performance accuracy.
Summary
The Department of Labor's proposed rule, published in the Federal Register on March 31, 2026, introduces a landmark framework for evaluating fiduciary conduct in selecting 401(k) plan investment options. Although rooted in an executive order on democratizing access to alternative assets, the proposal's scope extends beyond alternative investments to encompass all designated investment alternatives, establishing clearer fiduciary standards for defined contribution plan management.
The centerpiece of the proposal is a process-based safe harbor containing six evaluation factors. Fiduciaries who objectively, thoroughly, and analytically consider each factor—Performance, Fees, Liquidity, Valuation, Performance Benchmark, and Complexity—will be presumed to have satisfied their ERISA Section 404(a)(1)(B) fiduciary duties and receive significant judicial deference. This approach fundamentally shifts evaluation from outcomes to process, allowing fiduciaries to demonstrate prudence through rigorous methodology rather than actual investment results.
To operationalize the framework, the DOL embedded 20 illustrative examples directly within the proposed rule text. These examples address specific factual scenarios applicable to each factor, providing plan fiduciaries with concrete guidance on implementing the safe harbor across diverse investment categories. This non-exhaustive approach grants fiduciaries flexibility while establishing benchmarks for acceptable fiduciary practice.
The proposal addresses a substantive gap in prior DOL guidance, which had effectively discouraged inclusion of alternative assets—including private equity, private credit, digital assets, and cryptocurrency—in 401(k) menus. By establishing this safe harbor framework, the rule opens the door for broader alternative asset integration within retirement plans while maintaining fiduciary accountability. Plan fiduciaries can now include professionally managed, diversified alternative investments if they document their adherence to the six-factor evaluation process.
The comment period for this proposal closes June 1, 2026, allowing stakeholders—including plan sponsors, investment managers, and service providers—to provide feedback before final rulemaking. The safe harbor's adoption would represent a significant evolution in ERISA fiduciary standards, offering clearer process-based compliance pathways for investment selection decisions.
