Executive answer
An intangible may be hard to value when transferred early, reliable comparables do not exist and future cash flows depend on highly uncertain assumptions. Waiting for the result is not the solution: price must be assessed using information reasonably available when independent parties would have agreed.
Subsequent outcomes may help test whether original assumptions were reasonable or reasonably available information was omitted. They do not automatically prove the original valuation was wrong. Separate foreseeable facts, contemplated risks, extraordinary events and later decisions changing the asset.
The hard-to-value intangibles, or HTVI, approach appears in the OECD Guidelines 2022. It is a technical and interpretive framework, not an autonomous Mexican provision. Any use in Mexico must connect to Mexican law, the arm’s-length standard, facts and taxpayer rights.
When difficulty arises
Signals include a partly developed intangible, uncertain commercialization, no reliable comparables, sensitive projections, a long pre-revenue period, approval-dependent rights, novel technology or contingent payments. A signal does not automatically make an asset HTVI, but calls for discipline.
Define the transferred right. A pending patent, code, formula, data, know-how or territorial right has different risks. Record stage, life, territory, exclusivity, restrictions, enhancements and obligations. Valuing “technology” without rights makes financial precision irrelevant.
Identify who controls development and risks after transfer. If the buyer makes unplanned investment or enhancements, later results do not belong solely to the original asset.
Information timeline
| Moment | Question | Evidence |
|---|---|---|
| Before negotiation | Which alternatives existed? | offers, strategy, market |
| Valuation date | What information was available? | data room, studies, budget |
| Signing | Which assumptions were accepted? | contract, model, committee |
| Development | Which events occurred? | milestones, tests, decisions |
| Launch | What changed from plan? | approval, demand, price |
| Ex post | Which outcomes arose? | sales, costs, adoption |
| Review | Was deviation foreseeable? | causal analysis |
Freeze the model and source files at the date. An overwritten model prevents separation of original knowledge from hindsight.
Assumptions to document
Document volume, price, share, costs, investment, life, obsolescence, probability of success, approvals, competition and discount rate. Explain source, owner and range. Do not present one figure as certainty.
Separate controllable and external variables. The buyer may decide investment and launch; it does not control regulation or macroeconomics. Document correlations and dependencies. Avoid double-counting risk in both cash flows and discount rate without explanation.
Compare projections with approved plans and capacity. Aggressive growth needs people, capital, channels and timing. Assumptions should be consistent across valuation, budget, board and financing.
Scenarios and probabilities
Build scenarios representing economic paths, not arbitrary percentage changes. For technology: technical failure, delayed approval, base case and accelerated adoption. Assign probabilities with contemporaneous evidence and identify decision owners.
Use sensitivity analysis for critical variables. Show which combinations materially change value. This can inform contingent payments, milestones or adjustments independent parties might consider.
Do not calibrate probabilities to reach a target price. Compare with historical projects, approval rates and external evidence. Record uncertainty that cannot be quantified.
Valuation method
An income approach is often relevant without comparables, but requires incremental cash flows attributable to the right. Separate returns from other assets, services and functions. Define horizon, terminal value, tax, working capital and discounting.
Relief from royalty may suit brands or licensable technology; with-and-without may suit contracts or relationships; excess earnings may suit certain assets. Each depends on data. Triangulation can expose inconsistencies, not automatically create an average.
Historical cost rarely measures future value alone, though it validates capacity and stage. Document rejected methods.
Discount rate and consistency
The rate should match currency, horizon, stage, geography and cash-flow risks. Document date, sources, capital structure, risk-free rate, premium, beta, debt cost, size and specific adjustments. Do not add a generic premium merely because the asset is “new.”
Compare risks already reflected in scenarios. If expected cash flow weights technical failure, loading the same risk into the rate reduces value twice. Other systematic or unmodeled risks may require treatment. Prepare a risk–cash flow–rate table.
Discount currency must match cash flows. Nominal forecasts require a nominal rate; inflation and terminal growth must be compatible. Check whether rates in other group documents contradict the valuation without explanation.
If valuation depends on a projection file that keeps changing after signing, preserve the original version and build a timeline before interpreting outcomes.
Ex post evidence without hindsight
Compare projection and result by variable, period and cause, not total sales alone. Deviation may arise from price, volume, launch, cost, exchange, added investment or an external event. Identify when each fact became known.
Ask whether independent parties would have anticipated the event and addressed it through discount, clause, contingent payment or no adjustment. A genuinely unforeseeable event should not mechanically rewrite price.
Review subsequent decisions. If the buyer doubled investment, opened markets or integrated another asset, separate later-created value. If it abandoned a project for its own reasons, the loss does not prove zero value at transfer.
Illustration
A related party transfers technology to Mexico before regulatory approval. Valuation assigns a 60% chance of approval in two years, sales in three markets and further development funded by Mexico. One year later approval arrives early, a competitor exits and sales exceed plan.
The review does not automatically replace 60% with 100%. It asks what was known at transfer, whether timing and competitor exit were foreseeable, and which later investment Mexico made. If contemporaneous studies already showed a much higher probability and were omitted, the original assumption weakens. If the regulator unexpectedly accelerated and the competitor left due to a later event, the deviation may reflect new information.
Separate value in the original technology from Mexico-funded development. Compare variable by variable and retain negotiation communications. A high outcome is evidence to investigate, not an automatic conclusion.

Link records and decisions. “Market changed” is not a sufficient cause.
Contracts and contingent mechanisms
Independent parties may use earn-outs, milestones, variable royalties, options or review clauses under high uncertainty. That does not mean every HTVI needs future adjustment. Evaluate alternatives and risks.
The agreement should define metrics, audit, currency, tax, control, manipulation, termination and disputes. A vague clause can add uncertainty. Align accounting and transfer pricing.
Do not create a clause retrospectively. If parties amend, document new information and negotiation.
DEMPE and later enhancements
Map who developed before and after. One initial valuation may include buyer-funded future development; another may cover the current state only. Confusing them changes cash flows.
If the seller continues work, decide whether it supplies a service, shares risk or retains rights. If the buyer enhances, separate enhancement returns. Budgets, repositories and decisions prove contributions.
Check whether functions and staff moved or only title. Rights have value in relation to exploitation capacity.

Model governance
Maintain a variable dictionary, sources, links and owners. Protect formulas and test totals, signs, dates and units. Independent review should recalculate a sample and trace figures to records. Version every change with reason and approval.
Control bias. Business may overstate to approve investment; buyer may understate to negotiate; seller may emphasize synergies. Compare the same team’s historical forecasts and explain recurring errors. Tax should not alter commercial assumptions without evidence, but should challenge inconsistency.
Document negotiation: offers, ranges, trade-offs and clauses. Agreed price may differ from a valuation midpoint because of risk and alternatives. Explain the difference instead of forcing the model to equal price.
Outcome review
Review at defined intervals. Preserve original projection, actual result, updated forecast and causal explanation. Do not erase the baseline. Separate estimate changes, scope changes and errors.
For material deviation, bring valuation, business, legal and tax together. Decide whether it requires documentation only, activates a clause or warrants further analysis. Do not book an adjustment without reviewing contract and tax effects.
The report should distinguish facts known at the date, later information and judgment. This discipline prevents both hindsight abuse and uncritical defense of every projection.
Questions for independent review
- Does the model value the exact transferred right?
- Were all source files available at the valuation date?
- Do scenarios represent real decision paths?
- Are probability and discount-rate risks duplicated?
- Can capacity support projected growth?
- Do board and financing forecasts tell the same story?
- Which buyer investments create later value?
- Which event caused each material deviation?
- Was that event reasonably foreseeable?
- Would independent parties have used contingent terms?
- Does the agreement implement the valuation premise?
- Can another reviewer reproduce the conclusion?
Record answers, evidence and unresolved items. A simple “yes” checklist is insufficient; each material assumption needs an owner and source. Where information was unavailable, explain why the selected approach remained reasonable and what alternative was considered.
Common errors
- Valuing without defining rights.
- Using one scenario only.
- Adjusting probabilities to achieve price.
- Failing to preserve the original model.
- Treating every deviation as proof of error.
- Ignoring later investment and decisions.
- Double-counting risk.
- Averaging incompatible methods.
- Attributing new buyer contributions to the original asset.
- Describing HTVI as an automatic Mexican rule.
Governance and review
Set monitoring milestones without necessarily making them price adjustments: approval, launch, first revenue, material deviation and strategy change. Archive data and causes at each.
Valuation, business, legal, tax and accounting should review. The model owner controls versions. A committee approves assumptions and changes. Internal audit can test traceability.
Set materiality and frequency. Monthly review of a long-lived asset creates noise; ignoring it for five years loses evidence. Follow economic milestones.
