Another example of an activity that may involve intra-group services is manufacturing or assembly operations. The activities can take a variety of forms including what is commonly referred to as contract manufacturing. In some cases of contract manufacturing the producer may operate under extensive instruction from the counterparty about what to produce, in what quantity and of what quality. In some cases, raw materials or components may be made available to the producer by the counterparty. The production company may be assured that its entire output will be purchased, assuming quality requirements are met. In such a case the production company could be considered as performing a low-risk service to the counterparty, and the cost plus method could be the most appropriate transfer pricing method, subject to the principles in Chapter II.
