Proskauer Hedge Start: Accepting Investments from Benefit Plan Investors Subject to ERISA

Hedge fund managers face a critical regulatory inflection point when accepting capital from benefit plan investors subject to the Employee Retirement Income Security Act of 1974 (ERISA) or Section 4975 of the Internal Revenue Code. According to Proskauer Rose LLP's "Hedge Start" guidance, special compliance rules apply to funds that attract investments from entities including traditional pension plans, 401(k) plans, individual retirement accounts (IRAs), and Keogh plans—collectively defined as "Benefit Plan Investors."

The regulatory trigger mechanism centers on a precisely defined 25% ownership threshold. Under ERISA's "plan assets" regulation, a hedge fund's assets are deemed to be plan assets subject to fiduciary and prohibited transaction provisions if, immediately following any acquisition, disposition, transfer, or redemption of fund interests, Benefit Plan Investors own 25% or more of the value of any class of equity in the fund. Critically, interests held by the fund manager and its affiliates are excluded from both the numerator and denominator when calculating this percentage, providing managers with structural flexibility in their investor composition analysis.

Compliance with ERISA's fiduciary responsibility and prohibited transaction provisions represents a substantial operational burden for fund managers unfamiliar with these regulatory regimes. As a result, the predominant industry practice is for hedge fund managers to maintain Benefit Plan Investor ownership deliberately below the 25% threshold at all times, thereby avoiding triggering plan asset designation and its attendant regulatory obligations. This defensive positioning reflects the complexity and resource intensity required to operate as an ERISA-compliant fund, effectively creating a self-imposed cap on institutional pension and retirement capital that many managers are unwilling to accept.
