Business Combinations [Abstract] |
Business combinations | Business combinations Kirin-Amgen, Inc. During the first quarter of 2018, we acquired the remaining 50% ownership of Kirin-Amgen, Inc. (K-A) from Kirin Holdings Company, Limited (Kirin), making K-A a wholly owned subsidiary of Amgen. Upon its acquisition, K-A’s operations have been included in our condensed consolidated financial statements commencing on the share acquisition date. The acquisition relieved Amgen of future royalty obligations to K-A. K-A is a corporation that was established in 1984 as a 50-50 joint venture with Kirin to fund the global development of EPOGEN® (epoetin alfa). Over time, the scope of the collaboration was expanded to also include the products NEUPOGEN® (filgrastim), Neulasta® (pegfilgrastim), Aranesp® (darbepoetin alfa), Nplate® (romiplostim) and brodalumab. K-A held the intellectual property for each of these products and licensed the associated marketing rights in Asia to Kyowa Hakko Kirin (KHK), Kirin’s pharmaceutical subsidiary, and in most other territories to Amgen. In return, Amgen and KHK paid royalties to K-A, and K-A reimbursed Amgen and KHK’s research and development (R&D) expenses. K-A had also given Johnson & Johnson (J&J) exclusive licenses to manufacture and market recombinant human erythropoietin for all geographic areas of the world outside the United States, China and Japan. Under this agreement, J&J pays royalties to K-A based on product sales. Prior to the share acquisition date, we owned 50% of K-A and accounted for our interest in K-A by using the equity method of accounting, which included recording our share of K-A’s profits or losses in Selling, general and administrative expense in the Condensed Consolidated Statements of Income. The carrying value of our equity method investment in K-A was $570 million as of December 31, 2017, and was included in Other assets in the Condensed Consolidated Balance Sheet. The transaction was accounted for as a step acquisition of a business in which we were required to remeasure our existing 50% ownership interest at fair value. In addition, we were required to effectively settle our preexisting relationships with K-A, which resulted in a loss. Together the gain on the remeasurement of our existing ownership interest and the loss from the settlement of the preexisting relationship resulted in a net gain of $80 million, which was recorded in Interest and other income, net, in the Condensed Consolidated Statements of Income. The primary means of consideration for this transaction was a payment of $780 million in cash. The aggregate share acquisition date consideration to acquire the remaining 50% ownership in K-A and the fair value of Amgen’s preacquisition investment consisted of the following (in millions):
|  | Amount
Total cash paid to Kirin |  | $ | 780 |
Fair value of contingent consideration obligation |  | 45 |
Loss on settlement of preexisting relationship |  | (168 | )
Total consideration transferred to acquire K-A |  | 657 |
Fair value of Amgen’s investment in K-A |  | 825 |
Total acquisition date fair value |  | $ | 1,482 |
In connection with this acquisition, we are obligated to make single-digit-percentage royalty payments to Kirin contingent upon sales of brodalumab. The estimated fair value of this contingent consideration obligation is $45 million as of the share acquisition date. The fair values of assets acquired and liabilities assumed included cash of $977 million, licensing rights of $470 million, deferred tax liabilities of $102 million, other assets and liabilities of $131 million and goodwill of $6 million. The estimated fair value of acquired licensing rights was determined by using a probability-weighted income approach, which discounts expected future cash flows to present value by using a discount rate that represents the estimated rate that market participants would use to value the assets. The projected cash flows were based on certain assumptions, including estimates of future revenues and expenses and the time and resources needed to maintain the assets through commercialization. The licensing rights will be amortized over a weighted-average period of four years by using the straight-line method. The excess of the share acquisition date consideration over the fair values assigned to the assets acquired and the liabilities assumed of $6 million was recorded as goodwill, which is not deductible for tax purposes. The $131 million in other assets and liabilities represents primarily receivables for royalties earned by K-A, but not yet received, offset partially by payables representing R&D expenses incurred, but not yet reimbursed by K-A. The fair value estimates for the assets acquired and liabilities assumed were based on preliminary calculations and valuations, and our estimates and assumptions are subject to change as we obtain additional information during the measurement period (up to one year from the share acquisition date). The primary areas of those preliminary estimates that are not yet finalized relate to the valuation of licensing rights, contingent consideration and tax-related items. Pro forma results of operations for this acquisition have not been presented because this acquisition is not material to our consolidated results of operations.
