A pension plan is an employee benefit plan established or maintained by an employer or by an employee organization (such as a union), or both, that provides retirement income or defers income until termination of covered employment or beyond. There are a number of types of retirement plans, including the 401(k) plan and the traditional pension plan, known as a defined benefit plan.
Most private sector pension plans are covered by the Employee Retirement Income Security Act (ERISA). Among other things, ERISA provides protections for participants and beneficiaries in employee benefit plans, including providing access to plan information. Also, those individuals who manage plans (and other fiduciaries) must meet certain standards of conduct under the fiduciary responsibilities specified in the law.
The Employee Benefits Security Administration (EBSA) of the Department of Labor is responsible for administering and enforcing these provisions of ERISA.
