## Overview of ERISA Pension Regulations

The Employee Retirement Income Security Act of 1974 (ERISA) is the primary federal law governing private pension and employee benefit plans in the United States. ERISA establishes comprehensive standards and requirements for the establishment, operation, and termination of pension plans offered by private employers. The Act's primary objectives are to protect the interests of participants in employee benefit plans and ensure the equitable provision of retirement, health, and other welfare benefits. 

Under ERISA, private pension plans must comply with detailed rules regarding plan funding, vesting, fiduciary duties, and the distribution of benefits. Failure to adhere to ERISA's requirements can expose plan administrators, employers, and other fiduciaries to civil and criminal penalties. Aggrieved plan participants also have a federal right of action to recover benefits, enjoin violations, or obtain other appropriate equitable relief. See 29 U.S.C. § 1132(a).

## Fiduciary Duties under ERISA

A cornerstone of ERISA is the imposition of strict fiduciary duties on those responsible for the management and administration of pension plans. ERISA §404(a) requires that plan fiduciaries discharge their duties "solely in the interest of the participants and beneficiaries" and "with the care, skill, prudence, and diligence under the circumstances then prevailing that a prudent man acting in a like capacity and familiar with such matters would use." 29 U.S.C. § 1104(a)(1).

The Supreme Court has interpreted this "prudent person" standard to require fiduciaries to "engage in a reasoned decision-making process, consistent with that of a 'prudent' person." Tibble v. Edison Int'l, 575 U.S. 523, 530 (2015). Fiduciaries must also diversify plan investments to "minimize the risk of large losses" unless it is clearly imprudent to do so. 29 U.S.C. § 1104(a)(1)(C).

Breaches of fiduciary duty under ERISA can take many forms, including imprudent investment decisions, self-dealing, or failure to monitor plan service providers. Fiduciaries found liable may be required to make the plan whole for any losses, disgorge any profits, and in some cases, be removed from their positions. See 29 U.S.C. § 1109(a).

## Vesting and Accrual of Pension Benefits

A primary goal of ERISA is to ensure that employees participating in private pension plans are able to accrue and vest in their retirement benefits over time. ERISA sets specific requirements regarding the minimum rate at which participants must accrue benefits (the "accrual rate") and the maximum period of service an employee can be required to complete before becoming vested in their accrued benefits (the "vesting schedule").

For defined benefit pension plans, ERISA generally requires a minimum 1% annual accrual rate. 29 U.S.C. § 1054(b)(1)(A). Employees must also become 100% vested in their accrued benefits after no more than 5 years of service. 29 U.S.C. § 1053(a)(2)(A). For defined contribution plans, such as 401(k)s, ERISA mandates either full and immediate vesting or graduated vesting over no more than 6 years. 29 U.S.C. § 1053(a)(2)(B).

Failure to provide the required accrual rates or vesting schedules can subject pension plans to disqualification by the IRS and expose the plan sponsor to liability for benefits that should have accrued. Employees denied benefits due to improper vesting can sue to recover the full value of their accrued benefits. See Redington v. Snider, 475 F. Supp. 3d 1001 (C.D. Cal. 2020).

## Pension Plan Funding Requirements

In addition to benefit accrual and vesting rules, ERISA imposes strict funding requirements on private pension plans to ensure they have sufficient assets to pay promised benefits. Defined benefit plans, in particular, must make annual contributions sufficient to cover the present value of benefits accruing that year ("normal cost") plus an amortized portion of any unfunded liabilities. 29 U.S.C. § 1082.

The funding rules are complex, but generally require plans to maintain a funding ratio of at least 80% of projected liabilities. Plans that fall below this threshold are subject to additional contribution requirements and benefit restrictions until the funding level is restored. 29 U.S.C. § 1083. Failure to meet ERISA's funding obligations can lead to plan termination by the Pension Benefit Guaranty Corporation (PBGC) and the imposition of excise taxes. See PBGC v. R.A. Gray & Co., 467 U.S. 717 (1984).

## Pension Benefit Distribution and Participant Protections

ERISA also regulates how pension benefits are distributed to participants and beneficiaries. The Act requires that pension plans provide certain default forms of benefit payment, such as a qualified joint and survivor annuity for married participants. 29 U.S.C. § 1055. Plans must also obtain spousal consent before paying benefits in any other form.

Additionally, ERISA prohibits the assignment or garnishment of pension benefits, with limited exceptions, to protect participants from creditors and ensure the equitable distribution of retirement savings. 29 U.S.C. § 1056(d). This anti-alienation rule was a key factor in the Supreme Court's decision in Guidry v. Sheet Metal Workers Nat'l Pension Fund, 493 U.S. 365 (1990), which held that pension benefits could not be garnished to satisfy a constructive trust arising from the participant's criminal misconduct.

ERISA also grants participants the right to obtain certain information about their pension plans, including plan documents, financial reports, and individual benefit statements. 29 U.S.C. § 1024(b). Failure to provide required disclosures can subject plan administrators to civil penalties. SeeChed v. Reliance Standard Life Ins. Co., 918 F.3d 63 (2d Cir. 2019).

## Conclusion

The Employee Retirement Income Security Act establishes a comprehensive federal regulatory framework for private pension plans. ERISA's provisions governing fiduciary duties, vesting, funding, and benefit distribution aim to protect the interests of plan participants and ensure the equitable provision of retirement benefits. Strict compliance with ERISA's requirements is essential for employers, plan administrators, and other fiduciaries to avoid civil and criminal penalties, as well as costly lawsuits from aggrieved participants.
