Executive answer
An intercompany receivables assignment is not priced by applying a generic rate to nominal balance. First define what transfers: enforceable rights, default risk, delay, dilution, currency, collection functions and recourse against the seller. Then estimate what an independent factor would pay on that date considering expected cash flow, costs, capital, servicing and realistic alternatives.
The “factoring” label does not decide whether the transaction is a true sale of receivables, a loan secured by receivables, a collection service or a combination. Agreement, debtor notice, control of cash, recourse, conduct and recording should align. A quarterly transfer with automatic repurchase of every overdue invoice may leave substantially more risk with the seller than the title suggests.
A defensible price decomposes nominal value, expected loss, time value, FX, dilution, costs and return. It also demonstrates business purpose and each entity’s capacity to enter the arrangement.
Characterization tree
- Does the receivable exist, is it enforceable and assignable?
- Did legal rights and collection control transfer?
- Was the debtor notified or does it pay a controlled account?
- Who bears default, delay, dispute and return risk?
- Is there recourse and for which events?
- Who services, collects and litigates?
- Who bears currency and rate exposure until payment?
- Does the buyer have capital and risk capacity?
- Is consideration fixed, variable or adjustable?
- Does conduct confirm the agreement?
The answers determine the model. Do not begin by searching for a “factoring spread.”
Define the portfolio
Prepare an invoice-level file showing debtor, jurisdiction, relationship, date, maturity, currency, amount, product, dispute, credit note, guarantee, subsequent payment and recovery. Aggregate only afterward. A 60-day average can combine new invoices with severely overdue debt.
Reconcile the file to subledger, general ledger, tax invoice or equivalent support, bank statements and confirmations. The nominal transferred should be reproducible on the date. Identify taxes and components that do not form part of the economic right.
Separate related and third-party debtors. Where debtors are affiliates, risk depends on policies and group support; do not assume sovereign quality or no risk. Document concentration by debtor, industry, country and currency.
Record aging, default, dilution and recovery history. Use a sufficient window and explain product or collection changes. Later data may test estimates but should not replace information available when pricing occurred.
Recourse and retained risks
Read “non-recourse” in full. Representations may cover existence, eligibility, fraud, disputes, contractual performance or dilution. A seller may repurchase an invoice because of a commercial return rather than credit default. Classify events.
In recourse factoring determine when and how much the buyer may recover. If the seller covers every nonpayment, the transaction may resemble financing secured by receivables; discount then relates to seller risk, collateral and service. If the buyer genuinely bears credit loss, it needs information, control and capacity.
Analyze delay as well as default. A receivable paid 90 days late consumes liquidity even if fully recovered. Examine limits, first-loss positions, deductibles, reserves and overcollateralization.
Dilution includes credit notes, returns, discounts, errors, offsets and disputes. It can exceed default in some businesses. Determine who controls and receives compensation for it.
Servicing functions
Map origination, credit approval, invoicing, monitoring, reminders, cash application, negotiation, legal collection and write-off. If the seller continues all functions, it may provide a service to the buyer. Define standard, cost, fee and incentives.
Servicing does not necessarily mean retaining credit risk, but poor conduct can affect price and recourse. An independent arrangement would include metrics, reporting, cash segregation, audit and termination rights.
If customers pay the seller’s bank account, establish an appropriate trust, segregated account or remittance obligation. Measure hold days and liquidity benefit. Month-end reconciliation can hide temporary use of funds.
Build the price
A conceptual bridge starts with nominal and subtracts or adds components:
| Component | Question |
|---|---|
| time value | when is collection expected? |
| credit loss | probability and severity of default? |
| dilution | which returns or credits reduce cash? |
| delay | how variable is collection date? |
| FX | who bears currency until recovery? |
| servicing | who collects and at what cost? |
| capital and operations | which resources does the buyer require? |
| concentration | which non-diversifiable risk exists? |
| recourse/guarantee | which loss returns to seller? |
| return | what would an independent participant require? |
Discount expected cash flows using a rate consistent with currency, term and risk. Avoid counting expected loss twice: when cash flows already reflect default, the rate should not include the same component without adjustment.
Methods and comparables
An internal CUP may exist where the business sells comparable receivables to an independent factor. Compare debtors, recourse, aging, currency, servicing, volume, date and rights. A published factoring price is not comparable without those conditions.
Another approach builds required return from a currency and term reference, credit risk, capital, operations and margin. An expected-cash-flow model may work invoice by invoice. Use more than one approach as a reasonableness check where data permit.
Separate arrangement, availability, servicing or administration fees should relate to functions. Calculate all-in yield so that a low discount does not conceal high fees.

Valuation date and information cutoff
Value on the assignment date with then-available information. Preserve a portfolio snapshot, payment curves, ratings, rates, FX and approvals. Where price later adjusts for performance, define a prospective formula and limits rather than rewriting price discretionarily.
In revolving programs every purchase may contain a different portfolio. Establish eligibility criteria, recalibration frequency and concentration testing. A single annual rate can cease to represent risk when customers or maturities change.
Subsequent collections support back-testing. Compare actual loss, dilution and days with assumptions, explain variance and update future cohorts. Favorable results do not prove there was no risk at inception.
Currency and hedging
Where portfolio and purchase price use different currencies, model FX. Define conversion date and hedge owner. If the buyer pays pesos for dollar receivables and receives dollars, it may assume exposure or hedge it. Count the cost once.
Where price is a percentage of invoice-currency nominal, document the exchange rate for accounting and settlement. Reconcile FX with the treasury map rather than mixing it into factor yield.
Buyer capacity and purpose
The buyer should be able to fund purchases, analyze the portfolio and bear assigned risk. Identify committee, systems, people, capital and limits. A company with no personnel receiving one annual report may struggle to show daily control, although documented services may assist it.
Explain purpose: liquidity, centralized credit, working-capital reduction or data access. Compare alternatives such as a loan, shorter terms, securitization or external factoring. Realistic alternatives influence price and conditions.
For the seller, show that cash and risk transfer address a need and that price does not destroy value without reason. For the buyer, model return after losses and costs.
Illustrative case
A Mexican distributor assigns a dollar portfolio each month to a related finance company. Nominal is 100 and average expected collection is 75 days. The seller continues servicing and repurchases disputed invoices, but not insolvency defaults. Five customers represent 65%.
The model separates retained dilution, transferred default, servicing cost, concentration, time value and FX. The servicing agreement sets a fee and daily remittance. Price is not “intercompany rate plus 2%”; it is built from cash flows and checked against an adjusted external quote.
Three months later one customer pays late. The result does not retrospectively change the estimate when delay was within the range. It informs back-testing and the next cohort.
Legal, accounting and tax
Legal should confirm assignability, enforceability, notice, priority, insolvency, data protection, recourse and jurisdiction. Accounting should assess derecognition under the applicable framework. Accounting does not replace tax delineation, but inconsistency requires explanation.
Tax should review income recognition, deductions, interest, withholding, VAT and other effects based on form and facts. Do not assume every discount is interest or every service has the same treatment. Reconcile consideration, tax invoice/support, collections and returns.
Control balances between seller and buyer. Unremitted collections may become additional financing. Define interest, term and limit.
Warning signs
- portfolio sold without invoice listing;
- identical pricing for all currencies and debtors;
- “non-recourse” with routine repurchases;
- buyer without data or decisions;
- free servicing without analysis;
- commingled cash remitted late;
- discount adjusted only after a loss;
- ignored concentration;
- nominal value that does not reconcile;
- agreement, accounting and conduct that conflict.
Each sign requires investigation rather than an automatic conclusion.
Minimum file
Retain assignment and servicing agreements; eligibility rules; invoice snapshot; aging; default, dilution and recovery history; ratings; concentrations; cash-flow model; rates and FX; comparables; recourse; capacity; alternatives; approvals; notices; collections; reconciliations; back-testing and legal, accounting and tax treatment.
The memorandum should let a reviewer reconstruct why an independent buyer would pay that amount on that date.
Eligibility criteria and reserves
A revolving program needs objective rules for admitting invoices: maximum age, approved debtor, no dispute, confirmed delivery, currency, jurisdiction, concentration and documentation. Log rejections and exceptions. If the seller can freely replace deteriorated receivables with good assets, transferred risk may be reduced; replacement solely to cure a breached representation has a different effect.
Define dilution, concentration and servicing reserves and the point of release. A reserve is not automatically part of price; it may be retained cash, security or contingent consideration. Model who earns return on the amount and what happens in insolvency. Reconcile opening reserve, usage, replenishment and ending balance.
Test termination or amortization triggers: aging deterioration, increased default, remittance breach, concentration or change of control. An independent buyer would not preserve static conditions after material deterioration. Consequences should be symmetric and observed in conduct.
Settlement mechanics
Document a waterfall for each cohort: eligible nominal, discount, reserve, fees, purchase cash, collections, repurchases, losses, release and final settlement. Every component needs an account and date. Use an identifier following each invoice from sale through closure.
For variable consideration define data, formula, owner and deadline. Avoid clauses allowing one party to select assumptions after observing losses. Error correction should be distinguished from a new valuation.
Compare ex ante and ex post return. The former supports price; the latter tests whether the model needs updating. A high later return may reflect favorable outcomes, lower risk or better servicing. It is not automatically a compensating adjustment.
Governance and independent validation
A committee should approve program limits, methodology, counterparties and exceptions. Treasury manages liquidity; credit validates debtors; accounting reconciles; legal protects rights; tax reviews classification; transfer pricing tests comparability. Segregate origination from eligibility validation.
Sample invoices and confirmations. Recalculate discount, days and collections for a complete cohort. Compare the file delivered to the buyer against the original subledger and test that invoices were not assigned twice. Record remediation and closure date for every exception.
Data model for repeated programs
Store immutable snapshots rather than overwriting the live aging report. The data set should show invoice ID, cohort, assignment date, contractual maturity, expected date, actual date, reason code, recourse event, collection cost and currency. Maintain a dictionary so that “default,” “dispute” and “dilution” mean the same thing across entities.
Tie each model version to its data snapshot, market inputs and approval. A later reviewer should reproduce the purchase price without relying on a current system that has already applied payments and credit notes. Restrict manual changes and retain an audit log.
Back-testing should separate calibration error from portfolio mix. If losses rise because the program admitted a new customer segment, update segmentation rather than only increasing one global spread. If collection delays arise from the seller’s service failure, assess the servicing arrangement and recourse instead of charging all cost to credit risk.
Independent alternatives
Quantify the seller’s alternative: external factoring quote, revolving credit, delayed dividends or ordinary collection. Include fees, collateral, covenants, confidentiality and operational cost. The lowest headline rate may not be the most realistic option.
For the buyer compare use of funds, required capital and liquidity. It should not purchase a portfolio at a return below its realistic alternative without a documented strategic benefit. These alternatives do not mechanically set price, but they define the bargaining range an independent party would consider.
