Courts don't just challenge your rate. They challenge your methodology. A December 2022 ruling from France's Conseil d'État in France vs. Willink SAS is a case worth knowing. At issue: an intragroup convertible bond priced using Moody's RiskCalc, a synthetic credit rating tool. The French tax authorities argued the tool was too approximate to rely on. Two lower courts agreed. The Conseil d'État overturned both decisions. Its reasoning: financial markets rarely provide perfect comparables, and the arm's length standard does not require exact equivalence. Synthetic credit rating tools can legitimately support an arm's length interest rate determination — provided they are applied consistently, based on reliable data, and supplemented by a qualitative assessment of the borrower's risk profile and the specific features of the instrument. Three conditions. Not a rejection of the methodology. A standard to meet. The case was recently revisited in a June 2026 analysis by Deloitte Luxembourg in International Tax Review, alongside the Norwegian ExxonMobil ruling. Both underscore the same message: pricing must be grounded in credible credit risk analysis and coherent economic rationale. Zanders Transfer Pricing Solution embeds a credit rating methodology aligned with OECD Chapter X. It generates full documentation showing how each rating was derived: consistent, transparent, and audit ready. Not just a rate. A defensible analysis.
