The facts
ConocoPhillips Skandinavia AS (COPSAS) is the Norwegian operating entity of the ConocoPhillips group, incorporated in Norway and engaged in oil and gas production on the Norwegian continental shelf. It is a wholly owned subsidiary of ConocoPhillips Norge, a Delaware-incorporated intermediate holding entity within the ConocoPhillips group headquartered in Houston, Texas.
In May 2013, COPSAS entered into a five-year intra-group loan agreement with ConocoPhillips Norway Funding Ltd (COPN Funding), a group financing vehicle incorporated in Bermuda. The loan had a limit of NOK 20 billion. The agreed interest rate was the six-month Norwegian Interbank Offered Rate (NIBOR 6M) plus a fixed margin of 125 basis points — an all-in rate reflecting both the benchmark floating rate and COPSAS’s assessed credit risk.
COPSAS claimed deductions for the interest paid on this loan in Norwegian corporation tax returns for income years 2013 through 2017. On 8 March 2019 the Oil Tax Office (Oljeskattekontoret) issued a decision reducing the arm’s length margin to 75 basis points, disallowing the 50 basis point excess. The adjustments across the five income years totalled approximately NOK 287 million in disallowed interest expense.
COPSAS challenged the Oil Tax Office decision before the District Court (tingrett), which upheld the assessment. COPSAS then appealed to the Court of Appeal (lagmannsrett).
The decision
The Court of Appeal dismissed COPSAS’s appeal and upheld the Oil Tax Office assessment in full. The central issue was the appropriate standalone credit rating for COPSAS and the credit spread that rating implied. COPSAS had commissioned a report from PwC which estimated its standalone credit rating at between BBB− and BBB+. On that basis, COPSAS argued that a margin of 125 basis points was consistent with arm’s length terms. The Court of Appeal did not find the PwC estimates credible. Its reasoning turned on three interconnected points.
Benchmark currency
COPSAS operates exclusively on the Norwegian continental shelf under a special petroleum tax regime, with revenues, costs, and tax obligations all denominated in Norwegian kroner (NOK). A loan of NOK 20 billion could not realistically have been raised in the Norwegian bond market, which is too small for an issuance of that size, meaning COPSAS would have had to borrow in the international dollar market and incur currency swap costs. The court rejected any adjustment for those swap costs on the basis that COPN Funding, as an intra-group lender, bore no genuine currency risk — gains and losses on currency movements within the group stay within the group. Where the actual loan is denominated in NOK and repayable in NOK, the arm’s length analysis must reflect that directly.
Subsidiary premium
COPSAS’s own expert introduced a subsidiary premium adjustment of 30 to 50 basis points at the Court of Appeal stage, having not raised it before the District Court. The court noted this inconsistency and gave it limited weight. The point illustrates a broader issue: arguments and adjustments not introduced at first instance will face an uphill battle on appeal.
The credit rating itself
The court found that the PwC BBB− to BBB+ range did not adequately reflect COPSAS’s actual credit position as a large, profitable, Norwegian continental shelf operator with stable petroleum revenues and a strong regulatory framework. The Oil Tax Office’s margin of 75 basis points, consistent with a higher-quality credit assessment, was upheld as the arm’s length outcome.
ajiho commentary
Credit rating, implicit support, and the standalone fiction
COPSAS was part of one of the world’s largest energy groups. An independent lender extending NOK 20 billion to an entity in that position would price the loan with full awareness of the group context — not purely on a hypothetical standalone basis. The OECD’s Chapter X guidance, and the S&P framework for notching group entities, are directly relevant here. The court’s effective outcome — reducing the margin to 75 basis points — is consistent with recognising that a large, cash-generative subsidiary of an investment-grade parent would borrow at materially tighter spreads than a genuinely independent BBB entity. A credit rating report that produces a BBB− standalone rating for a Norwegian petroleum operator of COPSAS’s scale requires very specific justification to be credible.
Currency of the benchmark
The rejection of dollar-market comparables and swap-cost adjustments is significant and has been consistent across Norwegian petroleum sector litigation. Where the actual loan is denominated and repayable in a local currency, the comparable must reflect that directly. Constructing a benchmark from international dollar markets and layering adjustments on top introduces additional assumptions that courts have repeatedly declined to accept. This is a practical constraint on benchmarking methodology that affects any group with a Norwegian borrower.
Norway as an active and consistent enforcement jurisdiction
This case sits within a clear line of Norwegian transfer pricing decisions on intra-group loan margins — Exxonmobil Production Norway, Hess, Petrolia — in which the Oil Tax Office has consistently challenged margins that exceed what the borrower’s credit position supports, and has consistently prevailed. Groups with Norwegian operating entities carrying intra-group debt should treat this as a live and recurring risk rather than a settled area.
What this means for your business
On credit rating methodology: a rating report that does not engage directly with the borrower’s sector, revenue stability, regulatory environment, and implicit group support is unlikely to withstand scrutiny. The standalone rating is not the output of a generic model applied to financial ratios — it is an assessment of credit risk that must reflect the specific facts of the borrower’s position.
On benchmark currency: where the loan is denominated in a local currency, prioritise comparables in that currency. Adjustments from dollar-denominated benchmarks introduce assumptions that Norwegian courts have consistently declined to accept.
On expert evidence: arguments and adjustments not introduced at first instance will face an uphill battle on appeal. The credit methodology, and all adjustments to it, should be fully developed before the District Court stage.
