Unspecified Methods
What are the "unspecified methods" for valuing intangible property allowed by the transfer pricing regulations?
Section 482 offers four transfer pricing methodologies for use with intangible property, the fourth of which is listed as "unspecified methods," which are further defined as:
    (d) Unspecified methods--(1) In general. Methods not specified in 
					paragraphs (a)(1), (2), and (3) of this section may be used to evaluate 
					whether the amount charged in a controlled transaction is arm's length. 
					Any method used under this paragraph (d) must be applied in accordance 
					with the provisions of Sec. 1.482-1. Consistent with the specified
					methods, an unspecified method should take into account the general 
					principle that uncontrolled taxpayers evaluate the terms of a 
					transaction by considering the realistic alternatives to that 
					transaction, and only enter into a particular transaction if none of the 
					alternatives is preferable to it. For example, the comparable 
					uncontrolled transaction method compares a controlled transaction to 
					similar uncontrolled transactions to provide a direct estimate of the 
					price the parties would have agreed to had they resorted directly to a 
					market alternative to the controlled transaction. Therefore, in 
					establishing whether a controlled transaction achieved an arm's length 
					result, an unspecified method should provide information on the prices 
					or profits that the controlled taxpayer could have realized by choosing 
					a realistic alternative to the controlled transaction. As with any 
					method, an unspecified method will not be applied unless it provides the 
					most reliable measure of an arm's length result under the principles of 
					the best method rule. See Sec. 1.482-1(c). Therefore, in accordance with 
					Sec. 1.482-1(d) (Comparability), to the extent that a method relies on 
					internal data rather than uncontrolled comparables, its reliability will 
					be reduced. Similarly, the reliability of a method will be affected by 
					the reliability of the data and assumptions used to apply the method, 
					including any projections used.
					    (2) Example. The following example illustrates an application of the 
					principle of this paragraph (d).
    Example (i) USbond is a U.S. company that licenses to its foreign 
					subsidiary, Eurobond, a proprietary process that permits the manufacture 
					of Longbond, a long-lasting industrial adhesive, at a substantially 
					lower cost than otherwise would be possible. Using the proprietary 
					process, Eurobond manufactures Longbond and sells it to related and 
					unrelated parties for the market price of $550 per ton. Under the terms 
					of the license agreement, Eurobond pays USbond a royalty of $100 per ton 
					of Longbond sold. USbond also manufactures and markets Longbond in the 
					United States.
					    (ii) In evaluating whether the consideration paid for the transfer 
					of the proprietary process to Eurobond was arm's length, the district 
					director may consider, subject to the best method rule of Sec. 1.482-
					1(c), USbond's alternative of producing and selling Longbond itself. 
					Reasonably reliable estimates indicate that if USbond directly supplied 
					Longbond to the European market, a selling price of $300 per ton would 
					cover its costs and provide a reasonable profit for its functions, risks 
					and investment of capital associated with the production of Longbond for 
					the European market. Given that the market price of Longbond was $550 
					per ton, by licensing the proprietary process to Eurobond, USbond 
					forgoes $250 per ton of profit over the profit that would be necessary 
					to compensate it for the functions, risks and investment involved in 
					supplying Longbond to the European market itself. Based on these facts, 
					the district director concludes that a royalty of $100 for the 
					proprietary process is not arm's length.
