However, in some limited circumstances, transfer pricing methods based on the estimated cost of reproducing or replacing the intangible may be utilised. Such approaches may sometimes have valid application with regard to the development of intangibles used for internal business operations (e.g. internal software systems), particularly where the intangibles in question are not unique and valuable intangibles. Where intangibles relating to products sold in the marketplace are at issue, however, replacement cost valuation methods raise serious comparability issues. Among other concerns, it is necessary to evaluate the effect of time delays associated with deferred development on the value of the intangibles. Often, there may be a significant first mover advantage in having a product on the market at an early date. As a result, an identical product (and the supporting intangibles) developed in future periods will not be as valuable as the same product (and the supporting intangibles) available currently. In such a case, the estimated replacement cost will not be a valid proxy for the value of an intangible transferred currently. Similarly, where an intangible carries legal protections or exclusivity characteristics, the value of being able to exclude competitors from using the intangible will not be reflected in an analysis based on replacement cost. Cost based valuations generally are not reliable when applied to determine the arm’s length price for partially developed intangibles ...
