This handbook focuses on private sector pension plans where a trustee or investment manager is responsible for investing the plan's assets. It provides information about finding out who is managing your pension money and about the rules that pension managers must follow. You will also learn whether those rules are being broken and what to do if you think there are problems. Tips on how to read the annual financial reports that ERISA requires private sector pension plans to file with the federal government are included.
