I. Introduction

This section refines the definitions of ‘party in interest’ and ‘prohibited transaction’ as applied in litigation involving TIAA. In Cunningham v. Cornell, TIAA simultaneously acted as recordkeeper, annuity issuer, and provider of other investment options. This case provides a clear framework for analyzing the structural conflicts and prohibited transactions associated with insurer-issued fixed annuities under ERISA and measuring damages.
II. Party in Interest
ERISA §3(14) defines a ‘party in interest’ broadly to include fiduciaries of the plan, service providers such as recordkeepers and consultants, employers sponsoring the plan, and any entity receiving direct or indirect compensation from the plan. TIAA is a party in interest in multiple capacities: as the recordkeeper, as the issuer of fixed annuity products, and as a provider of affiliated investment funds.
III. Prohibited Transactions Framework
A. Recordkeeping Compensation
As recordkeeper, TIAA received compensation directly from plan assets. Under ERISA §406(a)(1)(C), such arrangements constitute transactions with a party in interest, presumptively prohibited absent a statutory exemption.
B. Issuance of Fixed Annuities with Spread Profits
TIAA’s issuance of fixed annuities with hidden spreads also constitutes a prohibited transaction. The insurer profits directly from the difference between general account yields and crediting rates paid to participants. This implicates:
– ERISA §406(a)(1)(A) and (C): transfer of plan assets to, or furnishing of services by, a party in interest;
– ERISA §406(b)(1): fiduciary self-dealing when TIAA retains discretion to set crediting rates.
Thus, both the recordkeeping function and the spread mechanism independently trigger prohibited transaction analysis.
IV. Damages and Disgorgement
The proper remedy for a prohibited transaction under ERISA §409 is restitution or disgorgement of all profits obtained through the unlawful conduct. Disgorgement is an equitable remedy designed to restore participants to the position they would have occupied absent the prohibited transaction. It prevents unjust enrichment by requiring fiduciaries or parties in interest to surrender profits obtained at the expense of plan participants.
Disgorgement does not require proof of participant reliance or precise quantification of the general account yield. Instead, once a prohibited transaction is established, the burden shifts to the fiduciary or party in interest to demonstrate that no loss occurred. If they cannot, all spread profits must be disgorged.
Courts have repeatedly recognized this principle in fiduciary breach cases. In Brotherston v. Putnam, the First Circuit affirmed that once a fiduciary breach and related loss are shown, the burden shifts to fiduciaries to prove that the same losses would have occurred absent the breach. The Supreme Court in Hughes v. Northwestern reaffirmed the ongoing duty to monitor investments and remove imprudent ones.
Applied to TIAA, disgorgement would require the company to return the difference between what its general account earned and what it credited to participants. For example, if the general account earned 6% and participants received 4.5%, TIAA would be required to disgorge the 150 basis points retained as spread. This figure has been documented in the range of 120–150 basis points annually, as cited in NBC News (2024) and subsequent independent analyses. Importantly, the industry has not disputed these figures, underscoring their credibility. As TIAA has consistently had the highest rates among fixed IPG annuities, damages for other fixed annuities will be the TIAA 150bps spread plus the difference in yield between the other annuity and TIAA.
The Discovery Barrier: General Account Returns
In practice, litigants face years of stonewalling when requesting general account return data. Insurers argue that such information is proprietary and competitive. Thus, while the spread is the true measure of insurer profits, direct calculation is often impossible.³
This creates a paradox: the central harm (undisclosed spread profits) is simultaneously the central figure withheld in discovery. Plaintiffs risk being left without a calculable damages model, even when the fiduciary breach is clear.
Alternative Damage Models: Disgorgement
The Maersk complaint provides a practical alternative: a disgorgement-based model. Under this theory, insurers must disgorge all profits derived from the prohibited transaction, irrespective of plaintiffs’ ability to calculate them precisely. Courts have long recognized disgorgement as an equitable remedy in ERISA cases. See Donovan v. Bierwirth, 754 F.2d 1049 (2d Cir. 1985).⁴
Reasonable Estimates and Fiduciary Latitude
Even absent full disclosure, courts may allow plaintiffs to use reasonable estimation methods:
– Comparator Returns — Using published yields on insurer-issued bonds or peer general account disclosures.
– Stable Value Benchmarks — Data from Hueler Stable Value Universe or Morningstar stable value indices.
– Economic Inference — Expert testimony showing spreads between credited rates and general account yields.
In Brotherston, the First Circuit endorsed damages models based on benchmarks rather than precise historical data.² Similarly, in Tibble v. Edison Int’l, 575 U.S. 523 (2015), courts accepted inferential models when defendants obstructed discovery.⁵
Policy Concerns and Fiduciary Implications
If insurers are allowed to withhold general account data, fiduciaries cannot meet their duty of prudence or loyalty. This regulatory gap highlights why annuities should not be default investments in ERISA retirement plans. Allowing equitable remedies such as disgorgement, and granting plaintiffs latitude in estimation, ensures fiduciary accountability despite insurer opacity.
V. Expert Commentary
TIAA annuities highlight the risks of structural conflicts and undisclosed spreads. As stated in NBC News (2024), annuities ‘flunk the most basic investment principle of diversification—do not put all your eggs in one basket.’ Public reporting has confirmed that TIAA annuities retain hidden spread fees of 120–150 basis points annually. Importantly, this figure has not been disputed by the industry. While other insurers may present even greater risks, TIAA remains the most visible example of how spread-based compensation undermines fiduciary protections.
VI. Conclusion
In Cunningham v. Cornell, TIAA’s dual roles as recordkeeper and annuity issuer created multiple prohibited transactions. Both the direct recordkeeping compensation and the hidden annuity spreads represent transactions with a party in interest. Under ERISA, these arrangements are per se prohibited absent exemptions. The proper remedy is disgorgement of spread-based profits, ensuring that plan assets are used solely for the benefit of participants and beneficiaries. Disgorgement is not punitive but restorative—it returns ill-gotten gains and enforces the exclusive benefit rule at the heart of ERISA.
The core harm in fixed annuity cases is the hidden spread profit, but insurers’ refusal to disclose general account returns makes direct measurement nearly impossible.
Courts should recognize:
1. Spread profits are per se compensation and subject to ERISA’s prohibited transaction rules.
2. Insurers’ refusal to disclose data should not immunize them from liability.
3. Plaintiffs are entitled either to full disgorgement of profits or to rely on reasonable estimates from comparator data.
Only by adopting these principles can ERISA fulfill its purpose of protecting plan participants from hidden and excessive fees.
