What is a fundamental duty of fiduciaries under ERISA?

The fundamental duty of fiduciaries under the Employee Retirement Income Security Act (ERISA) includes the obligation to diversify investments. This duty is crucial because diversification helps to spread risk among various assets, thereby reducing the potential for significant losses due to the poor performance of specific investments. By diversifying, fiduciaries act in the best interest of plan participants and beneficiaries, adhering to the prudence standard set forth by ERISA.

Fiduciaries are expected to evaluate the plan's investment options critically and ensure that the portfolio is not overly concentrated in any single investment or type of investment. This practice safeguards the retirement assets and promotes long-term growth, ultimately benefiting the employees relying on these plans for their financial security upon retirement.

Ensuring a properly diversified portfolio is integral to fulfilling fiduciary responsibilities effectively, given the volatile market conditions that can affect retirement savings.
