Business Combinations [Abstract]
Acquisitions [Text Block]	Note 3: Acquisitions During 2014 and 2012, we completed the acquisitions of Lohmann SE (Lohmann AH) and ChemGen Corporation (ChemGen), respectively. These acquisitions were accounted for as business combinations under the acquisition method of accounting. The assets acquired and liabilities assumed were recorded at their respective fair values as of the acquisition date in our consolidated financial statements. The determination of estimated fair value required management to make significant estimates and assumptions. The excess of the purchase price over the fair value of the acquired net assets, where applicable, has been recorded as goodwill. The results of operations of these acquisitions are included in our consolidated financial statements from the date of acquisition. Neither acquisition was material to our consolidated financial statements. During 2014, we announced an agreement to acquire Novartis Animal Health (Novartis AH), which was subsequently completed in January 2015. Details of our acquisitions of businesses are further discussed below. In addition to the acquisitions of businesses, we also acquired assets in development in 2014 and 2013 which are further discussed below in Product and Other Acquisitions and in Note 4. Upon acquisition, the acquired IPR&D related to these products was immediately written off as an expense because the products had no alternative future use. For the years ended December 31, 2014 and 2013, we recorded acquired IPR&D charges of $200.2 million and $57.1 million, respectively, associated with these transactions. There were no acquired IPR&D charges in 2012. Acquisitions of Businesses Subsequent Event - Novartis AH Acquisition Overview of Transaction On January 1, 2015, we acquired from Novartis AG all of the shares of certain Novartis subsidiaries and all of the assets of other Novartis subsidiaries that are exclusively related to the Novartis AH business in an all-cash transaction for a total purchase price of approximately $5.4 billion, subject to working capital and other adjustments. As of December 31, 2014, there was $5.41 billion of cash held in escrow for the pending acquisition of Novartis AH. This cash was classified as restricted cash, a noncurrent asset, on our consolidated balance sheet. The accounting for the acquisition and the results of the Novartis AH operations will be included in our financial statements for the period beginning on January 1, 2015. As a condition to the clearance of the transaction under the Hart-Scott-Rodino Antitrust Improvement Act, following the closing of the acquisition of Novartis AH, we divested certain animal health assets in the U.S. related to the Sentinel^® canine parasiticide franchise to Virbac Corporation for approximately $410 million. The acquired Novartis AH business consists of the research and development, manufacture, marketing, sale and distribution of veterinary products to prevent and treat diseases in pets, farm animals, and farmed fish. Under the terms of the agreement, we acquired manufacturing sites, research and development facilities, a global commercial infrastructure and portfolio of products, a pipeline of projects in development, and employees. Assets Acquired and Liabilities Assumed The initial accounting for this acquisition is incomplete. Significant, relevant information needed to complete the initial accounting is not available because the valuation of the assets acquired and liabilities assumed is not complete. As a result, determining these values is not practicable and we are unable to disclose these values or provide other related disclosures at this time. Supplemental Pro Forma Information Our unaudited pro forma consolidated revenue for 2014 is approximately $20.7 billion. This amount was determined as if the portion of Novartis AH that we retained after the sale to Virbac had been acquired as of January 1, 2014. This unaudited pro forma consolidated revenue is not necessarily indicative of what our consolidated revenues actually would have been had we completed the acquisition on January 1, 2014. Lohmann AH Acquisition On April 30, 2014, we acquired Lohmann AH, a privately-held company headquartered in Cuxhaven, Germany, through a stock purchase for a total purchase price of $591.2 million, comprised of $551.4 million of net cash plus $39.8 million of assumed debt. Lohmann AH is a global leader in poultry vaccines. As part of this transaction, we acquired the rights to a range of vaccines, commercial capabilities, and manufacturing sites in Germany and the United States. Preliminary amounts currently recorded in connection with this acquisition include $275.4 million of marketed product assets, $23.9 million of other intangible assets, $89.8 million of property and equipment, $243.7 million of goodwill, and $92.7 million of deferred tax liability, with $51.1 million of other net assets. The final determination may result in asset and liability fair values that differ from the preliminary estimates, but it is not expected that these differences will be material to our consolidated financial statements. Goodwill associated with this acquisition is not deductible for tax purposes. ChemGen On February 17, 2012, we acquired all of the outstanding stock of ChemGen, a privately-held bioscience company specializing in the development and commercialization of innovative feed-enzyme products that improve the efficiency of poultry, egg, and meat production, for total purchase consideration of $206.9 million in cash. In connection with this acquisition, we recorded $151.5 million of marketed product assets and $55.4 million of other net assets. Product and Other Acquisitions In connection with the arrangements described below, our partners may be entitled to future royalties based on sales should these products be approved for commercialization and/or milestones based on the successful progress of the drug candidate through the development process. In July 2014, we entered into a co-discovery and co-development collaboration with Immunocore Limited to research and potentially develop pre-clinical novel T cell-based cancer therapies. Upon entering the agreement, we paid an upfront fee of $45.0 million in cash and a related charge was recorded for acquired IPR&D. In September 2014, we entered into a collaboration agreement with AstraZeneca UK Limited (AstraZeneca) for the worldwide co-development and co-commercialization of AstraZeneca’s oral beta-secretase cleaving enzyme inhibitor known as AZD3293, a compound being investigated for the potential treatment of Alzheimer’s disease. At the time of the agreement, AZD3293 had completed Phase I testing in patients with early Alzheimer’s disease. We will be responsible for leading development efforts, while AstraZeneca will be responsible for manufacturing efforts. If successful, both parties will take joint responsibility for commercialization of AZD3293. Under the agreement, both parties will share equally in the ongoing development costs, gross margins and certain other costs associated with the commercialization of the compound. Upon execution of the agreement, we immediately recorded, as an acquired IPR&D charge, our obligation associated with a payment of $50.0 million which we will pay to AstraZeneca in 2015. In December 2014, we entered into a collaboration agreement with Adocia for the worldwide development and commercialization of Adocia's ultra-rapid insulin, known as BioChaperone Lispro, a compound being developed for the treatment of patients with type 1 and type 2 diabetes. BioChaperone Lispro is currently in Phase I studies. We will be responsible for leading development, manufacturing, and commercialization efforts. Upon entering the agreement, we paid an upfront fee of $50.0 million in cash and a related charge was recorded for acquired IPR&D. In December 2013, we acquired for $57.1 million in cash, all development and commercial rights for a calcitonin gene-related peptide antibody being studied as a potential treatment for the prevention of frequent, recurrent migraine headaches. At the time of the purchase, the product had completed a successful Phase II proof-of-concept study and a related charge was recorded for acquired IPR&D.
