Acquisition Marketed Vaccines Business of Baxter International Inc. (Baxter) On December 1, 2014 (which falls in the first fiscal quarter of 2015 for our international operations), we completed the acquisition of Baxter’s portfolio of marketed vaccines for a final purchase price of $648 million. The portfolio that was acquired consists of NeisVac-C and FSME-IMMUN/TicoVac. NeisVac-C is a vaccine that helps protect against meningitis caused by group C meningococcal meningitis and FSME-IMMUN/TicoVac is a vaccine that helps protect against tick-borne encephalitis. In connection with this acquisition, we recorded $376 million in Identifiable intangible assets, primarily consisting of $371 million in Developed technology rights. We also recorded $194 million of Inventories and $12 million in Goodwill. The final allocation of the consideration transferred to the assets acquired and the liabilities assumed has been completed. B. Collaborative Arrangements Collaboration with Eli Lilly & Company (Lilly) In October 2013, we entered into a collaboration agreement with Lilly to jointly develop and globally commercialize Pfizer’s tanezumab, which provides that Pfizer and Lilly will equally share product-development expenses as well as potential revenues and certain product-related costs. On March 23, 2015, Pfizer and Lilly announced that the companies are preparing to resume the Phase 3 clinical program for tanezumab. As a result, on March 27, 2015, we received a $200 million upfront payment from Lilly in accordance with the collaboration agreement between Pfizer and Lilly, which is recorded as deferred income in our condensed consolidated balance sheet and is being recognized into Other (income)/deductions––net over a multi-year period beginning in the second quarter of 2015. This announcement followed a decision by the U.S. Food and Drug Administration (FDA) to lift the partial clinical hold on the tanezumab development program after a review of nonclinical data characterizing the sympathetic nervous system response to tanezumab. Under the collaboration agreement with Lilly, we are eligible to receive additional payments from Lilly upon the achievement of specified regulatory and commercial milestones. Collaboration with OPKO Health, Inc. (OPKO) On December 13, 2014, we entered into a collaborative agreement with OPKO to develop and commercialize OPKO’s long-acting human growth hormone (hGH-CTP) for the treatment of growth hormone deficiency (GHD) in adults and children, as well as for the treatment of growth failure in children born small for gestational age (SGA) who fail to show catch-up growth by two years of age. hGH-CTP has the potential to reduce the required dosing frequency of human growth hormone to a single weekly injection from the current standard of one injection per day. We have received the exclusive license to commercialize hGH-CTP worldwide. OPKO will lead the clinical activities and will be responsible for funding the development programs for the key indications, which include Adult and Pediatric GHD and Pediatric SGA. We will be responsible for all development costs for additional indications, all postmarketing studies, manufacturing and commercialization activities for all indications, and we will lead the manufacturing activities related to product development. The transaction closed on January 28, 2015, upon termination of the waiting period under the Hart-Scott-Rodino Act. In February 2015, we made an upfront payment of $295 million to OPKO, which was recorded in Research and development expenses, and OPKO is eligible to receive up to an additional $275 million upon the achievement of certain regulatory milestones. OPKO is also eligible to receive royalty payments associated with the commercialization of hGH-CTP for Adult GHD, which is subject to regulatory approval. Upon the launch of hGH-CTP for Pediatric GHD, which is subject to regulatory approval, the royalties will transition to tiered gross profit sharing for both hGH-CTP and our product, Genotropin. C. Equity-Method Investment Investment in ViiV Healthcare Limited (ViiV) Our minority ownership interest in ViiV, a company formed in 2009 by Pfizer and GlaxoSmithKline plc (GSK) to focus solely on research, development and commercialization of human immunodeficiency virus (HIV) medicines, was impacted by the January 21, 2014 European Commission approval of Tivicay (dolutegravir), a product for the treatment of HIV-1 infection, developed by ViiV. This approval triggered a reduction in our equity interest in ViiV from 12.6% to 11.7%, effective April 1, 2014. As a result, in the first six months of 2014, we recognized a loss of approximately $28 million in Other (income)/deductions––net. D. Cost-Method Investment AM-Pharma B.V. (AM-Pharma) On April 9, 2015, we acquired a minority equity interest in AM-Pharma, a privately held Dutch biopharmaceutical company focused on the development of recombinant human Alkaline Phosphatase (recAP) for inflammatory diseases, and secured an exclusive option to acquire the remaining equity in the company. The option becomes exercisable upon delivery of the clinical trial report after completion of a Phase II trial of recAP in the treatment of Acute Kidney Injury related to sepsis. Results from the current Phase II trial for recAP are expected in the second half of 2016. Under the terms of the agreement, we paid $87.5 million for both the exclusive option and the minority equity interest, which was recorded as a cost-method investment in Long-term investments, and we may make additional payments of up to $512.5 million upon exercise of the option and potential launch of any product that may result from this investment.
