The denominator should be reasonably independent from controlled transactions, otherwise there would be no objective starting point. For instance, when analysing a transaction consisting in the purchase of goods by a distributor from an associated enterprise for resale to independent customers, one could not weight the net profit indicator against the cost of goods sold because these costs are the controlled costs for which consistency with the arm’s length principle is being tested. Similarly, for a controlled transaction consisting in the provision of services to an associated enterprise, one could not weight the net profit indicator against the revenue from the sale of services because these are the controlled sales for which consistency with the arm’s length principle is being tested. Where the denominator is materially affected by controlled transaction costs that are not the object of the testing (such as head office charges, rental fees or royalties paid to an associated enterprise), caution should be exercised to ensure that said controlled transaction costs do not materially distort the analysis and in particular that they are in accordance with the arm’s length principle ...
