The Employee Retirement Income Security Act (ERISA) was signed in 1974. The U.S. Department of Labor (DOL) is the agency responsible for administering and enforcing this law. For many years, most of ERISA's requirements applied to pension plans. However, in recent years that has changed, and group plans (called "welfare benefit plans" by ERISA and the DOL) now must meet a number of requirements. Government and church plans do not need to comply with ERISA.
