Employee Retirement Income Security Act of 1974 (ERISA) – A Federal law that sets standards of protection for individuals in most voluntarily established, private-sector retirement plans. ERISA requires plans to provide participants with plan information, including important facts about plan features and funding; sets minimum standards for participation, vesting, benefit accrual, and funding; provides fiduciary responsibilities for those who manage and control plan assets; requires plans to establish a claims and appeals process for participants to get benefits from their plans; gives participants the right to sue for benefits and breaches of fiduciary duty; and, if a defined benefit plan is terminated, guarantees payment of certain benefits through a federally chartered corporation, known as the Pension Benefit Guaranty Corporation (PBGC).
