A profit splitting factor based on expenses may be appropriate where it is possible to identify a strong correlation between relative expenses incurred and relative value contributed. For example, marketing expenses may be an appropriate factor for distributors-marketers if advertising generates unique and valuable marketing intangibles, e.g. in consumer goods where the value of marketing intangibles is affected by advertising. Research and development expenses may be suitable for manufacturers if they relate to the development of unique and valuable intangibles such as patents. However, if, for instance, each party contributes different valuable intangibles, then it is not appropriate to use a cost- based factor unless cost is a reliable measure of the relative value of those intangibles or costs can be risk-weighted to achieve a reliable measure of relative value. Even where each party contributes the same kind of intangibles, risk-weighting will be an appropriate consideration. For example, where the risk of failure at an early stage of development is several times higher than the risk of failure at a later stage or in the development of incremental improvements to an already proven concept, then the costs incurred in that early stage will have a higher risk weighting than the costs incurred at a later stage or on incremental improvements. Employee remuneration may be relevant in situations where functions relating to the skills and experience of staff are the primary factor in generating the relevant profits ...
