The US Department of Labor has reinforced the fiduciary framework governing 401(k) plans, setting clearer expectations for how trustees can incorporate alternative assets, including private equity, into retirement portfolios.

The guidance emphasises that fiduciaries must prioritise participants’ interests when selecting investments, ensuring that any allocation to alternative assets meets strict standards on risk, diversification, and transparency.

Trustees are required to follow a disciplined investment process, assessing factors such as fees, liquidity, performance, and overall portfolio fit before including more complex assets.

The framework allows for a broad range of investment options within 401(k) plans, provided fiduciaries can demonstrate that selections are prudent and aligned with long-term retirement outcomes.

The Department of Labor also highlighted the importance of clear disclosure, requiring plan administrators to provide participants with detailed information on investment options, associated risks, and fee structures.

The guidance reinforces that fiduciaries must act independently and avoid conflicts of interest, while ensuring that plan expenses remain reasonable.

It also places ongoing obligations on trustees to monitor investments and service providers, reflecting the dynamic nature of portfolio management.
