Plain English
Money moved inside a group still has to look like a real financing arrangement. That means asking two questions: is this actually debt, and if so, is the interest rate what an independent lender would have charged this borrower for this loan?
Technical definition
Chapter X requires accurate delineation of the financial transaction, including whether a purported loan should be regarded as a loan in whole or part, followed by pricing that reflects the borrower's credit standing, the terms, and the options realistically available to both parties.
Why it matters
Financing flows are large, easy for authorities to identify from the accounts, and frequently mispriced using group-level credit ratings rather than borrower-level ones.
How it works in practice
- 01Delineate: debt or equity, and in what amount.
- 02Determine the borrower's stand-alone credit rating, then consider implicit group support.
- 03Price using CUP where bond or loan comparables exist.
- 04For guarantees, quantify the benefit and split it between yield and cost approaches.
- 05For cash pools, reward the pool leader for its actual function, usually routine coordination.
Worked example
Implicit support on a subsidiary loan
A subsidiary rated BB stand-alone belongs to a group rated A-. Because default by a strategically important subsidiary would damage the group, an independent lender would price somewhere between the two. Notching the borrower up to BB+ or BBB- and pricing against that rating is a defensible outcome; using the group's A- rating without analysis is not.
Common mistakes
- Applying the parent's credit rating to every borrower.
- Perpetual short-term balances left unpriced.
- Cash pool leader earning a spread far beyond its functional profile.
- Ignoring thin capitalisation and interest limitation rules that operate alongside transfer pricing.
Audit red flags
- Loans with no repayment history over many years.
- Guarantee fees charged at a flat rate group-wide.
Documentation & data
Documents to hold
- Credit rating analysis for each borrower.
- Loan agreements with covenants and security.
- Cash pool policy and participant benefit analysis.
Data you need
- Borrower financial statements.
- Bond and loan market data.
- Daily pool balances.
Who owns this internally: Treasury owns execution; tax owns pricing and characterisation.
Jurisdiction notes
- OECD
- Chapter X on financial transactions was added in 2020 and covers treasury, guarantees, and captive insurance.
- European Union
- ATAD interest limitation rules cap deductibility independently of whether the rate is arm's length.
Notes by role
CFOs & finance leaders
Two separate tests must both be passed: the rate must be arm's length, and the deduction must survive interest limitation caps.
Frequently asked
- Can a tax authority recharacterise a loan as equity?
- Yes, where accurate delineation shows the funding does not have the features of debt, such as no realistic prospect of repayment.
