By way of illustration, the example of cost plus at paragraph 2.59 demonstrates the need to adjust the gross mark-up arising from transactions in order to achieve consistent and reliable comparison. Such adjustments may be made without difficulty where the relevant costs can be readily analysed. Where, however, it is known that an adjustment is required, but it is not possible to identify the particular costs for which an adjustment is required, it may, nevertheless, be possible to identify the net profit arising on the transaction and thereby ensure that a consistent measure is used. For example, if the supervisory, general, and administrative costs that are treated as part of costs of goods sold for the independent enterprises X, Y and Z cannot be identified so as to adjust the mark up in a reliable application of cost plus, it may be necessary to examine net profit indicators in the absence of more reliable comparisons ...
