Methodology

How we built the model and what assumptions drive it.

Framework

TariffRefundIQ uses a probability-weighted decision tree to estimate the expected present value of IEEPA tariff refund claims. This is a standard valuation methodology used in litigation finance, insurance, and private equity for pricing contingent assets.

The model defines seven mutually exclusive scenarios, each with three parameters:

  • Probability — likelihood this scenario materializes (must sum to 100%)
  • Recovery Rate — percentage of the claim face value recovered in this scenario
  • Timing — years until cash is received

NPV Calculation

Scenario NPV = Claim Value × Probability × Recovery Rate ÷ (1 + Cost of Capital)^Timing

The Expected Value is the sum of all scenario NPVs. This represents the risk-adjusted present value of holding the claim — the minimum price at which a rational seller should be willing to part with it.

Probability Estimates

Our probability estimates reflect analysis of:

  • Legal landscape: The 6-3 SCOTUS ruling is decisive, not a squeaker. The legal path to refunds is clear — the uncertainty is in execution, not law.
  • Political dynamics: The administration's stated intent to delay (2-5 years), personal attacks on majority justices, and rapid pivot to alternative tariff authorities all signal non-cooperation.
  • Historical precedent: Government refund mechanisms for illegally collected fees have precedent (Japanese internment reparations, various tax refund programs), but $175B is unprecedented in scale.
  • Institutional mechanics: CBP processing capacity, CIT enforcement powers, Treasury Judgment Fund access, and congressional appropriations dynamics.

We update probabilities as facts change. Pro subscribers are notified when material updates occur — CIT proceedings, congressional action, CBP guidance, or any shift in the political landscape.

Filing Status Adjustments

Recovery rates are adjusted based on how well-positioned the claim is:

Filing StatusRecovery AdjustmentRationale
1581(i) + Protest Filed100%Maximum protection — all recovery paths preserved
1581(i) Action Filed100%CIT jurisdiction established — strong position
Protest Filed Only90%Some entries may fall outside protest scope
Not Yet Filed60%Significant deadline risk — act immediately

What's Not Modeled

  • Statutory interest: 19 USC §1505 provides for interest on refunded duties. At current rates, this could add 5-10% to recovery. We treat this as upside to be conservative.
  • Legal costs: Litigation costs for maintaining claims are not deducted. These vary by claimant and are best estimated by counsel.
  • Tax implications: Refund proceeds may have tax consequences depending on how the original duties were treated. Consult a tax advisor.
  • Correlation risk: Scenarios are modeled as independent, but political outcomes may cluster (e.g., admin obstruction makes negotiated settlement more likely).

Limitations

This model provides a framework for thinking about claim value, not a guarantee of outcomes. Key limitations include:

  • • Probabilities are subjective estimates based on available information
  • • The political and legal landscape can change rapidly
  • • Individual claim characteristics (entry dates, liquidation status, protest timing) significantly affect recovery
  • • The $175B aggregate liability is unprecedented — historical precedent may not apply
  • • This is not legal, financial, or tax advice
