Description: The Employee Retiree Income Security Act, or ERISA, establishes an important statutory role for pension actuaries in the United States. As part of its statutory goal to protect the retirement security of America’s workers, ERISA requires tax-qualified defined benefit plans to obtain an actuarial valuation of plan reserves each year. When valuing the plan’s reserves, the actuary is required by ERISA to act on behalf of plan participants. Thus, the plan actuary fulfills an important role in maintaining the plan’s ability to meet its on-going obligations to the plan participants and their beneficiaries.
