(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 § 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 ...
