Structural Advantages, Structural Vulnerabilities, and the Transparency Divide

The level funded industry markets on a simple proposition: level funded gives the employer the upside of self-funding with the predictability of fully insured. The proposition is not false. It is incomplete in ways that matter for the employer making the purchasing decision. Level funded offers structural advantages over fully insured that are genuine and that this article names with specificity. It also carries structural vulnerabilities that the industry understates and that this article names with equal specificity. The transparency advantage that anchors the marketing is real but qualified: the employer sees more than they would in fully insured, and less than the marketing suggests. An honest evaluation of the level funded architecture requires naming both sides and identifying which employers the architecture serves well and which it does not.

The Genuine Structural Advantages

#

ERISA preemption provides benefits that are structural, not product-specific. They persist regardless of which TPA or stop loss carrier the employer selects. Exemption from state mandated benefits allows the employer to design the plan through the plan document, covering what the workforce needs rather than what the state legislature has mandated. Exemption from state premium taxes produces direct cost savings, with rates generally ranging from approximately 1.75 to 4 percent of the premium equivalent depending on the state. A single federal regulatory regime simplifies compliance for employers with employees in multiple states. These advantages are documented in LFP-01.03 and are not in dispute. They are consequences of the self-funded architecture, available to any self-funded plan, and level funded inherits them by being structured as self-funded under ERISA.

Surplus return potential is the financial advantage most frequently cited in the sales process. In fully insured, favorable claims experience benefits the carrier. In level funded, it can benefit the employer. The advantage is real but variable. As LFP-01.05 established, surplus return rates range from 100 percent to zero depending on contract terms. An employer evaluating the surplus advantage should ask for the specific return percentage in their contract and should request historical surplus return data from the TPA or stop loss carrier for comparable groups. The advantage is meaningful for an employer whose contract returns most or all of the surplus and whose group demographics suggest favorable claims experience. It is nominal for an employer whose contract returns nothing.

Claims data access is the operational advantage that creates the most downstream value. Level funded employers receive claims data showing utilization patterns, cost concentrations, provider pricing variation, and member health trends. This data enables plan design changes that respond to actual utilization rather than actuarial assumptions. An employer whose data shows that 40 percent of specialist visits are for musculoskeletal conditions can implement a musculoskeletal pathway program. An employer whose data shows high emergency department utilization for non-emergent conditions can add telehealth or urgent care incentives. None of these interventions are possible without the underlying data. The data also enables vendor evaluation: comparing network discount performance, PBM pass-through rates, and utilization management effectiveness across TPAs. In fully insured, the carrier controls data access. The employer receives aggregate summaries that are insufficient for any of these activities. The data advantage is structural: it follows from the employer’s ownership of the plan and the claims the plan generates.

Plan design flexibility allows the employer to customize benefits within ERISA and federal regulatory requirements. The plan document, not a state-mandated benefit schedule, governs coverage. An employer can add telehealth benefits or include direct primary care. The employer can carve out specialty pharmacy to a transparent PBM arrangement. The employer can implement reference-based pricing for certain services or design cost-sharing structures that incentivize high-value care. The flexibility is constrained by federal requirements, including the Mental Health Parity and Addiction Equity Act (MHPAEA), ACA preventive care mandates, and COBRA continuation obligations, but it is substantially broader than what fully insured employers have within the state-mandated benefit framework.

The Structural Vulnerabilities

#

Underwriting exposure at renewal is the vulnerability the industry acknowledges but underemphasizes. Level funded plans are underwritten annually. The stop loss carrier evaluates the group’s claims experience and adjusts pricing. A bad claims year can produce substantial premium increases at renewal, with broker and industry sources reporting increases of 20 percent, 40 percent, or more depending on the severity of the claims experience. This is fundamentally different from fully insured community rating, where the employer’s individual claims experience has limited direct impact on their premium because the cost is spread across the community-rated pool. An employer who selects level funded for cost savings in year one may face a substantial increase in year two if claims are unfavorable. The first-year savings that made level funded attractive can be erased by a single bad renewal. The employer who evaluates level funded on a one-year basis is making a decision that should be evaluated on a three-to-five-year horizon.

Stop loss laser risk is the most acute financial vulnerability in small group level funded. A member diagnosed with a chronic high-cost condition, whether during the plan year or identified through claims data at renewal, can be lasered: assigned a member-specific attachment point at or above the expected annual cost of their care. For a 15-person group, one lasered member with $200,000 in expected annual claims represents financial exposure that may exceed the employer’s capacity to absorb. The employer may not learn about the laser until the renewal process, leaving limited time to find alternative stop loss coverage, negotiate the laser terms, or exit the arrangement. The laser problem is not an edge case. It is a predictable consequence of health-status underwriting applied to small groups where one member’s condition can dominate the group’s risk profile. LFP-02.03 examines laser mechanics and the employer’s options in detail.

Administrative quality variance is a vulnerability that is difficult to evaluate before purchasing and difficult to remedy after. The TPA’s claims processing accuracy, network discount depth, utilization management effectiveness, compliance administration, and member services quality directly affect the employer’s financial outcomes and employee experience. TPA quality varies substantially across the market. Two TPAs charging the same PMPM can deliver materially different results. The employer relies on the broker’s recommendation, which as LFP-01.06 established may be influenced by the broker’s financial relationships with TPAs. Switching TPAs mid-plan-year is disruptive enough that most employers tolerate mediocre administration rather than undertake the transition. LFP-05.03 examines TPA operational quality and the evaluation problem.

Employer fiduciary responsibility is a vulnerability that most small employers do not know they carry. As the sponsor of a self-funded ERISA plan, the employer owes duties of loyalty and prudence to plan participants. The employer must act in participants’ interest when selecting the TPA, evaluating the stop loss carrier, making plan design decisions, and overseeing the claims fund. Most small employers sponsoring level funded plans do not have the benefits expertise to discharge these obligations and do not know the obligations exist. A 30-person landscaping company that selects level funded on broker recommendation has accepted the same fiduciary standard that applies to a Fortune 500 company’s benefits committee. The legal obligation is identical even though the resources available to fulfill it are not. Fiduciary liability is a legal risk that fully insured employers do not face, and it is not addressed in most broker presentations or carrier marketing materials.

The Transparency Divide

#

Level funded markets transparency as a categorical advantage. The reality is relative, not categorical.

What is transparent: component pricing breaks the monthly payment into claims fund, stop loss premium, and administrative fee as separate line items. In fully insured, the premium is a single undifferentiated number. Claims data shows utilization and cost at a level of detail unavailable in fully insured. Reconciliation shows whether claims ran above or below expectations and what happened to the surplus.

What is not transparent: stop loss underwriting methodology is a black box. The employer does not see the actuarial models, loss ratios, or pricing assumptions behind the stop loss premium. Sun Life, Voya, Symetra, and Tokio Marine HCC each use proprietary underwriting models, and the employer has no mechanism to determine whether their stop loss premium is competitive relative to other carriers without obtaining competing quotes. Obtaining those quotes requires broker initiative and market access that the employer cannot independently verify. Network discount methodology is presented as a percentage off billed charges, but whether those discounts from networks like PHCS/Multiplan, Aetna’s rental network, or First Health are competitive relative to other available networks requires a separate analysis that most small employers lack the resources to conduct. Broker compensation, despite CAA disclosure requirements, is frequently incomplete or obscured. Override commissions from stop loss carriers, production bonuses from TPAs, and carrier-specific incentive arrangements may not appear in the broker’s Section 408(b)(2) disclosure or may be disclosed in language that does not enable the employer to understand the magnitude or the conflict. TPA margin on pharmacy is invisible in many arrangements. If the TPA manages the PBM relationship through a spread arrangement with Express Scripts, CVS Caremark, or another PBM, the difference between what the PBM charges and what the plan pays is the TPA’s pharmacy margin, and the employer may not know it exists.

The transparency advantage is real. The employer sees more in level funded than they would in fully insured. The transparency is also partial. The employer does not see the stop loss carrier’s underwriting, the TPA’s network margins, the broker’s full compensation, or the PBM’s spread. The industry markets transparency as a categorical advantage when it is a relative advantage with significant gaps that the employer should know about before purchasing.

The Employer Fit Question

#

Level funded is structurally advantaged for employers with 15 to 50 relatively stable employees whose demographics are younger or healthier than the community-rated pool. These employers benefit from health-status underwriting that reflects their actual risk profile rather than the community average. Level funded is also advantaged for employers who value data access and plan design flexibility. The data enables cost management strategies that fully insured does not support. Employers with a broker or advisor capable of interpreting claims data and managing the TPA relationship extract more value from the architecture than those without advisory support. Multi-state employers benefit from ERISA preemption, which simplifies compliance across jurisdictions (see LFP-01.03).

Level funded is structurally disadvantaged for very small groups under 10 lives, where stop loss pricing from carriers like Symetra and HM Insurance Group reflects the higher actuarial variance and the economics become marginal or unfavorable. It is disadvantaged for employers with known high-cost members who will be lasered at underwriting, because the member’s care costs will fall entirely on the employer without stop loss reimbursement. Employers without benefits expertise or a capable advisor are at a disadvantage because they cannot evaluate TPA quality, interpret claims data, or discharge their ERISA fiduciary obligations. Employers who value administrative simplicity and complete risk transfer above all else are better served by fully insured. Employers in states with generous fully insured regulatory environments providing strong consumer protections forfeit those protections by moving to a self-funded ERISA plan.

The question is not whether level funded is good or bad. The question is whether the structural characteristics of this architecture match the specific employer’s situation, risk tolerance, and administrative capacity. The industry tends to answer this question with marketing. This series answers it with structure.
