Executive answer
Characterizing intercompany funding starts before pricing. The question is whether, using information available at origination, an independent lender would advance that amount with a realistic expectation of repayment and whether the borrower would accept the conditions. Where principal exceeds reasonable capacity, lacks an economic maturity, depends on future contributions or behaves like a residual participation, the “loan” title does not resolve the analysis.
Debt and equity are not distinguished through one financial ratio. Review purpose, cash flow, maturity, priority, covenants, security, subordination, payments, rights, alternatives and conduct. Mexican law also contains specific provisions concerning interest, back-to-back credits, thin capitalization and the arm’s-length principle that require legal analysis.
The conclusion may support the full amount as debt, only a portion, or prospective changes to terms. Do not improvise a recharacterization after losses are known. The contemporaneous file matters.
Characterization tree
- Is there a business purpose and identifiable use?
- Did the borrower need funds?
- Which available cash flow was expected?
- Can principal and interest be paid under reasonable scenarios?
- Is maturity and schedule enforceable?
- Which rights exist upon default?
- What is priority against other creditors?
- Is there subordination, conversion or profit participation?
- Which security and covenants would an independent lender require?
- Did the parties observe payments, monitoring and remedies?
If answers appear only after signing, origination was weak.
Purpose and alternatives
Document use: working capital, asset, acquisition, dividend, refinancing or losses. Tie drawdown to budget and bank account. A broad “general corporate purpose” can be legitimate but still requires support for amount and term.
Compare borrower alternatives: equity contribution, bank credit, lower dividend, asset sale, factoring or reduced investment. Evaluate cost, availability, covenants and operating effect. The alternative does not mechanically set price; it defines what would be accepted.
For the lender compare investments, deposits, external debt and use of liquidity. Determine why it would assume borrower risk. A parent may have strategic reasons, but the arm’s-length principle analyzes conditions between separate enterprises.
Where a project generates no cash for several years, a bullet loan may be possible with grace and support; initial equity may also be required. Model the actual profile rather than a standard schedule.
Debt capacity
Build cash available for debt service from historical statements, approved budget and testable assumptions. Separate EBITDA, working capital, investment, tax, dividends and existing debt. Reconcile opening and ending cash.
Calculate appropriate metrics: interest coverage, debt/EBITDA, cash flow/debt, fixed-charge coverage and liquidity. Do not use a universal threshold. Compare industry, cycle, currency and rating. A seasonal business requires monthly analysis, not only an annual total.
Model base, downside and stress cases. Change volume, margin, rate, FX, investment and delay. Determine maximum principal compatible with payments and covenants. If the base case barely pays interest without amortizing, explain why a lender would advance funds.
Include third-party debt and quasi-financial liabilities. Do not analyze each intercompany loan as though it were the only obligation. Consider cross-guarantees, cash pools and contingent commitments.
Maturity and amortization
Maturity should reflect the funded asset or need. Revolving working capital differs from a ten-year plant. Compare useful life, cash generation and reasonably available refinancing.
A perpetually renewed loan may remain debt when independent parties would renew under current conditions, but it requires a new decision and price at each date. Automatic extension after default without analysis weakens characterization.
Define amortization, prepayment, grace, events and fallback. A bullet requires evidence that cash or refinancing will exist at maturity. Do not rely solely on a hypothetical company sale.
Rights and priority
Document what the lender can do: demand, accelerate, enforce security, restrict dividends, obtain information or renegotiate. If it would never enforce because that harms the group, analyze conduct and support. This does not automatically eliminate debt, but the limitation needs explanation.
Compare contractual and structural subordination. Subordinated debt may remain debt with a higher return, but facts change if it absorbs losses like equity and lacks remedies. Identify insolvency priority and other creditor rights.
Convertible, participating or contingent-payment instruments require decomposition. Compensation may include debt and option components. Use appropriate valuation.
Rating and rate after characterization
Estimate rating only after determining principal and terms. Rating should reflect total debt, cash flow, industry, country, currency and group support. Reduced principal may have different risk from the original contractual amount.
Search comparables with the same seniority, term, currency, security and date. Rate does not repair principal that no independent party would lend. A 20% coupon can compensate some risk, but it does not create repayment expectation where none exists.
Calculate all-in return with fees and guarantees. Demonstrate that the borrower retains a benefit against alternatives.

Equity and future contributions
If the company needs recurring contributions to pay interest, examine whether the model was undercapitalized at inception or an unforeseeable event occurred. A binding capital commitment can support capacity but must be legally and financially credible.
Do not circularize cash: contribution, interest payment and new loan within days need explanation. Trace funds and purpose. Repetition may reveal that operating cash cannot support debt.
Regulatory capital, contractual reserves and dividend restrictions affect alternatives. Positive accounting equity does not ensure cash for debt service.
Subsequent conduct
Review timely payments, waivers, amendments, covenants, reports and collections. An independent lender reacts to default by demanding information, repricing, seeking security, suspending draws, restructuring or enforcing. Complete inaction is evidence.
Do not use later conduct to invent what was unknown at origination. Distinguish an unanticipated event from an unrealistic assumption. Document what the lender knew, what changed and why amendment was reasonable.
Amendments are transactions. Compare new conditions and alternatives on their date. Track capitalized interest, PIK, extensions and forgiveness.
Startups and loss periods
A startup or nearshoring investment may have expected losses and still obtain debt where it has assets, contracts, sponsor support or defensible future cash. Segment construction, ramp-up and operations. Align draws with milestones.
The model should show who absorbs overruns and what happens if volumes fail. An independent lender may require equity first, leverage limits, reserves or guarantees.
Do not retrospectively price every uncertainty through rate. Some risks are addressed through lower principal and covenants.
Illustrative case
A Mexican subsidiary needs MXN 120 million for a plant and ramp-up losses. The group proposes a five-year unsecured bullet loan. The base model generates cash from year three but pays only MXN 70 million at maturity; the stress case cannot service interest.
The analysis considers MXN 50 million of equity and MXN 70 million of debt, partial grace, amortization from year three and covenants. Rating and rate are then estimated for that structure. Benchmarking bonds for MXN 120 million would produce a precise rate for unsupported principal.
If the shareholder still advances the full loan, the file must analyze legal and tax consequences; it should not declare arm’s length merely by increasing coupon.
Interaction with Mexican rules
Arm’s-length characterization does not replace deduction requirements. Apply withholding, treaties, thin capitalization, net-interest limitation and other provisions afterward. Valid debt can still generate nondeductible interest.
The Mexican Income Tax Law also includes specific rules that may treat certain interest or back-to-back credits as dividends under stated conditions. Legal and tax teams should review current text, parties, guarantees, rights and flows. Do not generalize from accounting labels.
Keep separate conclusions for transfer-pricing economics, corporate form, accounting and tax effect. Explain differences.
Origination governance
Use a pre-approval pack containing request, purpose, cash flow, amount, alternatives, capacity, recommended principal, currency, term, security, rating, benchmark, tax limits, agreement and signatures. Assign conditions precedent.
Treasury should not approve a material transaction alone. Include business, CFO, legal, tax and transfer pricing. Record votes, conflicts and exceptions. Prevent drawdown before agreement and capacity work are complete.
Monitor indicators and covenants quarterly. Use a traffic-light action plan. A variance does not always require recharacterization, but it requires creditor behavior.
Adversarial questions
- Could the borrower obtain this principal outside the group?
- What will pay at maturity and where will it come from?
- What would a lender do under downside?
- Does the rate correspond to characterized principal?
- Do other creditors rank ahead?
- Is shareholder equity funding the debt payment?
- Are covenants and remedies observed?
- Was extension foreseeable at inception?
- Do agreement, accounting and conduct align?
- Were tax limitations calculated afterward?
Answer with figures and documents, not narrative alone.
Minimum file
Retain request, purpose, alternatives, statements, budget, model, scenarios, metrics, total debt, rating, comparables, term sheet, agreement, security, approvals, drawdowns, payments, covenants, waivers, amendments, withholding, tax limitations and reconciliations.
Update after a material event. Preserve origination and amendment analyses separately.
A reproducible quantitative model
The capacity file should separate assumptions, formulas and results. Include comparable historical statements, a bridge to budget, monthly calendar, currency, taxes, working capital, investment, dividends, debt and minimum cash. Mark which assumptions came from the business and which the analyst adjusted.
Calculate service for each instrument using actual priority and dates. An annual total can hide that March lacks liquidity even though December shows cash. Model floating interest, amortization and covenants by period. If repayment depends on refinancing, include cost, availability and conditions rather than an unexplained cash inflow.
Compare requested principal against three perspectives: cash-flow capacity, comparable credit metrics and available asset or security value. None is automatically controlling. Explain why industry, stage or country differences support adjustments. Preserve results before and after those adjustments.
Require second-person validation. Recalculate formulas, trace figures to statements and test signs, units and exchange rates. A small scale or period error can change the characterization.
Covenants as evidence of discipline
Covenants translate risk into action. Define metrics, thresholds, frequency, certificates, cure periods and consequences. They may address coverage, leverage, liquidity, additional debt, dividends, asset sales or information. Tailor them to the risk rather than copying a list.
Document negotiation and opening headroom. A covenant breached under the original budget is not credible protection. For waivers record information reviewed, consideration, period and conditions. Compare what a bank would require.
Monitoring without action is also insufficient. The committee should approve action, owner and deadline. Repeated exceptions may indicate that the real instrument differs from the contract.
Funding restructuring
When capacity falls, prepare alternatives before amendment: partial repayment, equity contribution, extension, rate reduction, PIK, security, conversion or forgiveness. Value existing rights and each party’s position. An independent creditor would not surrender value without considering recovery and costs.
Debt-to-equity conversion carries corporate, accounting and tax effects that need separate review. Do not use conversion to erase a deficient historical analysis. Preserve original rationale, later events, negotiation and effective date.
Where capacity improves, renewal still needs updating. The borrower may have better alternatives and negotiate a lower rate or release security. Apply the principle symmetrically.
Consistency with group planning
Reconcile the loan with capital budget, dividend plan, cash pool and operating agreements. An entity cannot simultaneously claim that all cash is needed for debt service and plan an extraordinary dividend without explaining priority. Nor should debt fund a loss that the intercompany pricing policy was meant to compensate.
Review consolidated and local scenarios. Group solvency does not replace borrower capacity, although support may affect risk. Identify guarantees, support letters and implicit support so they are not counted twice.
Evidence from external financing
Third-party bank facilities provide valuable evidence but require adjustment. Compare borrower, date, purpose, collateral, covenants, tenor, currency and committed amount. A bank’s small secured revolver does not prove capacity for a large unsecured bullet loan.
Review rejected applications and lender questions, not only signed agreements. They show which amount or protection independent parties required. Preserve term sheets and credit committee feedback where available.
Where the group borrows externally and on-lends, external debt is not automatically a CUP. The local borrower may have different risk, term and rights, and central treasury may perform functions. Still, the external package helps test whether the internal structure is commercially coherent.
