Every intercompany loan raises the same underlying question: what interest rate would this borrower have obtained from an independent lender, on these terms, at this point in time? Answering it requires more than pulling a benchmark yield curve. It requires establishing a standalone credit rating for the borrowing entity, because the loan's arm's length pricing hinges entirely on the risk profile the market would have assigned to it absent group membership.
Why the Group Rating Isn't the Borrower's Rating
Multinational groups typically carry a consolidated or parent credit rating that reflects the strength of the group as a whole. Applying that rating directly to a subsidiary's standalone borrowing overstates the subsidiary's true creditworthiness unless a guarantee or comparable explicit support genuinely exists. Rating agencies and TP practitioners instead derive a standalone rating for the borrowing entity based on its own financial ratios, industry position, and country risk, then apply notching adjustments to reflect the degree of implicit support it would realistically receive without a formal guarantee.
Building the Notched Rating
The notching exercise typically starts from the parent or group rating and works downward, applying discrete notch reductions for factors such as the subsidiary's strategic importance to the group, the degree of operational and financial integration, the jurisdiction's country risk ceiling, and the absence of any explicit guarantee or letter of comfort. The resulting standalone rating, often several notches below the parent, becomes the anchor for identifying comparable third-party debt instruments.
Selecting the Right Comparables
Once a standalone rating is established, comparable loan or bond pricing is sourced by matching tenor, currency, seniority, security, and covenant package as closely as possible. Loan-level databases are generally preferred over bond databases because bonds are typically issued by larger, more liquid issuers with different risk and liquidity premia than a typical intercompany loan. Where the loan terms include unusual features, bullet repayment, subordination, or an unusually long tenor, additional adjustments are needed to isolate the effect of those features from the base credit spread.
Cross-Border Complications
For loans between entities in different countries, the analysis must also account for currency risk, sovereign ceiling constraints on the borrower's rating, and, increasingly, the borrower jurisdiction's own thin capitalisation and interest deductibility limitations, which can cap the deductible interest independently of whether the rate itself is arm's length. A rate that is defensible under transfer pricing rules can still be partially disallowed under a separate interest limitation regime, so both analyses need to be run together rather than in isolation.
Tenor, Bullet Structures, and Other Term-Specific Adjustments
Intercompany loans frequently carry features that are less common in the third-party debt markets used for benchmarking, such as long fixed tenors, bullet repayment at maturity rather than amortising instalments, or subordination to other group debt. Each of these features shifts the risk profile relative to a plain-vanilla comparable, and a benchmarking study that borrows a comparable's coupon without adjusting for tenor and repayment structure differences understates the true comparability gap between the instruments being compared.
Conclusion
Chapter X makes the standalone credit rating, not the group rating, the anchor for intercompany loan pricing, and the notching analysis is the evidentiary bridge between the two. A loan rate benchmarked without a documented notched rating, matched to comparable tenor, seniority and repayment structure, does not satisfy the delineation and comparability requirements Chapter X sets out, regardless of how closely the headline rate tracks a generic yield curve.
