Goodwill and Intangible Assets Disclosure [Abstract]
Other Intangibles	Other Intangibles In connection with acquisitions, the Company measures the fair value of marketed products and research and development pipeline programs and capitalizes these amounts. See Note 2 for information on intangible assets acquired as a result of business acquisitions in the first six months of 2017 and 2016. During the second quarter and first six months of 2017, the Company recorded an intangible asset impairment charge of $47 million within Materials and production costs related to Intron A, a treatment for certain types of cancers. Sales of Intron A are being adversely affected by the availability of new therapeutic options. During the second quarter, sales of Intron A in the United States eroded more rapidly than previously anticipated by the Company, which led to changes in the cash flow assumptions for Intron A. These revisions to cash flows indicated that the Intron A intangible asset value was not fully recoverable on an undiscounted cash flows basis. The Company utilized market participant assumptions to determine its best estimate of the fair value of the intangible asset related to Intron A that, when compared with its related carrying value, resulted in the impairment charge noted above. The remaining intangible asset value for Intron A at June 30, 2017 was $25 million. During the second quarter and first six months of 2016, the Company recorded intangible asset impairment charges of $95 million and $347 million, respectively. During the second quarter of 2016, the Company wrote off amounts that had been capitalized in connection with in-licensed products that, for business reasons, the Company returned to the licensor. The remaining impairment charges of $252 million in the first six months of 2016 related to Zontivity, a product for the reduction of thrombotic cardiovascular events in patients with a history of myocardial infarction or with peripheral arterial disease. In March 2016, following several business decisions that reduced sales expectations for Zontivity in the United States and Europe, the Company lowered its cash flow projections for Zontivity. The Company utilized market participant assumptions and considered several different scenarios to determine the fair value of the intangible asset related to Zontivity that, when compared with its related carrying value, resulted in the impairment charge noted above. Also, during the second quarter and first six months of 2016, the Company recorded $195 million and $220 million, respectively, of IPR&D impairment charges within Research and development expenses. Of these amounts, $112 million related to an in-licensed program that, for business reasons, was returned to the licensor. The remaining IPR&D impairment charges primarily related to deprioritized pipeline programs that were deemed to have no alternative use during the period. The Company may recognize additional non-cash impairment charges in the future related to other marketed products or pipeline programs and such charges could be material.
