Where treating costs as pass-through costs is found to be arm’s length, a second question arises as to the consequences on comparability and on the determination of the arm’s length range. Because it is necessary to compare like with like, if pass-through costs are excluded from the denominator of the taxpayer’s net profit indicator, comparable costs should also be excluded from the denominator of the comparable net profit indicator. Comparability issues may arise in practice where limited information is available on the breakdown of the costs of the comparables ...

In applying a cost-based transactional net margin method, fully loaded costs are often used, including all the direct and indirect costs attributable to the activity or transaction, together with an appropriate allocation in respect of the overheads of the business. The question can arise whether and to what extent it is acceptable at arm’s length to treat a significant portion of the taxpayer’s costs as pass-through costs to which no profit element is attributed (i.e. as costs which are potentially excludable from the denominator of the net profit indicator). This depends on the extent to which an independent party in comparable circumstances would agree not to earn a mark-up on part of the costs it incurs. The response should not be based on the classification of costs as “internal” or “external” costs, but rather on a comparability (including functional) analysis. See paragraph 7.34 ...

One question that arises in cases where the net profit indicator is weighted against sales is how to account for rebates and discounts that may be granted to customers by the taxpayer or the comparables. Depending on the accounting standards, rebates and discounts may be treated as a reduction of sales revenue or as an expense. Similar difficulties can arise in relation to foreign exchange gains or losses. Where such items materially affect the comparison, the key is to compare like with like and follow the same accounting principles for the taxpayer and for the comparables ...
