1 Introduction In general, the IAM National 401(k) Plan was created for employees who are represented for the purpose of collective bargaining by a lodge chartered by the International Association of Machinists and Aerospace Workers (IAM). The Plan is administered by a Board of Trustees consisting of an equal number of representatives of the IAM and employers. The Trustees hire a Fund Director and office staff to handle some of the day-to-day administrative tasks. The Trustees have also retained a recordkeeper, John Hancock Retirement Plan Services, to assist in the administration of the Plan. Your rights to benefits from this Plan are governed by the terms of the Plan adopted by the Trustees. Only the Board of Trustees has the final authority to determine your eligibility for benefits and your right to participate in the Plan. The Board determines the provisions of the Plan and its interpretation and application. No person or organization, no union officer, district or local lodge employee, nor employer or employee representative, consultant or attorney is authorized to speak on behalf of the Board of Trustees on any matter related to this Plan. Every year the Plan’s Summary Annual Report will be sent to you. Who Can Participate in this Plan?
