Business Combinations [Abstract]
Acquisitions and divestitures	ACQUISITIONS AND DIVESTITURES Acquisitions during the six months ended June 30, 2018 Nasonex-branded products On May 29, 2018, we entered into a license agreement with Merck Sharp & Dohme Corp. ("Merck") allowing us to develop and commercialize an OTC version of Nasonex-branded products containing the compound, mometasone furoate monohydrate. The acquisition was accounted for as an asset acquisition based on our assessment that substantially all of the fair value of the gross assets acquired was concentrated in a single identifiable asset to be used for research and development. In accordance with Accounting Standards Codification Topic 730 Research and Development ("ASC 730"), the non-refundable upfront license fee of $50.0 million was recorded in Research and development ("R&D") expense in our CHCA segment because the intangible research and development asset acquired has no alternative use. The agreement requires us to make contingent payments if we obtain regulatory approval and achieve certain sales milestones. We will also be obligated to make royalty payments on potential future sales. The contingent consideration will be included in the measurement of the cost of the asset when the contingency is resolved, and the consideration is paid or becomes payable. Consideration paid after U.S. Food and Drug Administration ("FDA") approval will be capitalized and amortized to cost of goods sold over the economic life of each product. Divestitures during the six months ended July 1, 2017 On January 3, 2017, we sold certain Abbreviated New Drug Applications ("ANDAs") for $15.0 million to a third party, which was recorded as a gain in Other operating expense (income) on the Condensed Consolidated Statements of Operations in our Prescription Pharmaceuticals ("RX") segment. On February 1, 2017, we completed the sale of the animal health pet treats plant fixed assets within our CHCA segment, which were previously classified as held-for sale. We received $7.7 million in proceeds, which resulted in an immaterial loss. On April 6, 2017, we completed the sale of our India Active Pharmaceuticals Ingredient ("API") business to Strides Shasun Limited. We received $22.2 million of proceeds, inclusive of an estimated working capital adjustment, which resulted in an immaterial gain recorded in our legacy Other segment. Prior to closing the sale, we determined that the carrying value of the India API business exceeded its fair value less the cost to sell, resulting in an impairment charge of $35.3 million, which was recorded in Impairment charges on the Condensed Consolidated Statements of Operations for the year ended December 31, 2016.
