PBGC is a federal agency created by the Employee Retirement Income Security Act of 1974 (ERISA) to protect pension benefits in private-sector traditional pension plans known as defined benefit plans. If your plan ends (this is called "plan termination") without sufficient money to pay all benefits, PBGC's insurance program will pay you the benefit provided by your pension plan up to the limits set by law. (Most people receive the full benefit they had earned before the plan terminated.) Our financing comes from insurance premiums paid by companies whose plans we protect, from our investments, from the assets of pension plans that we take over as trustee, and from recoveries from the companies formerly responsible for the plans, but not from taxes. Your plan is insured even if your employer fails to pay the required premiums.
