In some cases, a significant issue for the reliability of cost-based splitting factors is the determination of the relevant period of time from which the elements of determination of the profit splitting factor(s) (e.g. assets, costs, or others) should be taken into account. A difficulty arises because there can be a lag between the time when expenses are incurred and the time when value is created, and it is sometimes difficult to decide which period’s expenses should be used. For example, in the case of a cost-based factor, using the expenditure on a single-year basis may be suitable for some cases, while in some other cases it may be more suitable to use accumulated expenditure (net of depreciation or amortisation, where appropriate in the circumstances) incurred in the previous as well as the current years. Depending on the facts and circumstances of the case, this determination may have a significant effect on the allocation of profits amongst the parties. As noted in Section C.5.1 above, the selection of the profit splitting factor should be appropriate to the particular circumstances of the case and provide a reliable approximation of the division of profits that would have been agreed between independent parties. The principles of this section are illustrated by Example 16 in Annex II to Chapter II of this guidance ...

In identifying and applying appropriate cost-based profit splitting factors a number of issues may need to be considered. One is that there may be differences between the parties in the timing of expenditure. For example, research and development costs that are relevant to the value of a party’s contributions may have been incurred several years in the past, whereas the expenditure for another party may be current. As a result, it may be necessary to bring historic costs to current values (as discussed further below) in addition to the risk weighting described in paragraph 2.181. The relevant costs may be part of a larger cost pool that needs to be analysed and allocated to the contributions made to the profit split transaction. For example, marketing costs may be incurred and recorded across several product lines, whereas only one product line is the subject of the profit split transaction. Where location savings retained by member(s) of the MNE group are a significant contributor to profits, and such costs are included in the profits to be split, then the manner in which independent parties would allocate retained location savings would need to be reflected in the profit split, taking into account the guidance in Section D.6 of Chapter I. Cost-based profit splitting factors can be very sensitive to differences and changes in accounting classification of costs. It is therefore necessary to clearly identify in advance what costs will be taken into account in the determination of the profit splitting factor and to determine the factor consistently among the parties ...
