Private fund managers need to understand what ERISA is, why ERISA matters and what exceptions are available to managers who do not want to be subject to ERISA as a manager of “plan assets.” At a recent event, ERISA practitioners from Simpson Thacher & Bartlett LLP; Proskauer Rose LLP; Skadden, Arps, Slate, Meagher & Flom LLP; and Wachtell, Lipton, Rosen & Katz discussed these issues and other ERISA-related developments applicable to organizing and operating private equity and hedge funds. This article, the first in a two-part series, summarizes insights from panelists on identifying benefit plan investors and exemptions available to fund managers under ERISA. The second installment will address drafting fund documents, ERISA-related liability and implications of the Sun Capital case.
