It should be noted that plans for nongovernmental private tax-exempt employers are subject to ERISA (unlike a governmental plan), except for church plans. Therefore, private tax-exempts must structure their 457 plans to take advantage of a top hat ERISA exemption (e.g., by allowing only a select group of management or highly compensated employees to participate). Otherwise, the plan would be subject to the exclusive purpose and funding requirements of Title I of ERISA, and a nongovernmental tax-exempt Section 457 plan cannot, by definition, meet those requirements.3
