Restructuring and Related Activities [Abstract]
Restructuring	Restructuring We continue to execute on the transformation and process improvement efforts announced in 2014. As part of these efforts, we committed to a more agile and efficient operating model. Our transformation and process improvement efforts across the Company are enabling us to reallocate resources to fund many of our innovative pipeline and growth opportunities that deliver value to patients and stockholders. The efforts include a restructuring, which is also delivering cost savings and is funding investments. As part of the restructuring, we have exited our facilities in Washington state and Colorado and are reducing the number of buildings we occupy at our headquarters in Thousand Oaks, California, as well as at other locations. We continue to estimate that we will incur $800 million to $900 million of pre-tax charges in connection with our restructuring, including (i) separation and other headcount-related costs of $535 million to $585 million with respect to staff reductions and (ii) asset-related charges of $265 million to $315 million consisting primarily of asset impairments, accelerated depreciation and other related costs resulting from the consolidation of our worldwide facilities. Through September 30, 2016, we have incurred $473 million of separation and other headcount-related costs and $225 million of asset-related charges. We expect that we will incur most of the remaining estimated costs through 2017 in order to support our ongoing transformation and process improvement efforts. The amounts related to the restructuring recorded in the Condensed Consolidated Statements of Income during the three and nine months ended September 30, 2016, were not significant. As of September 30, 2016, the total restructuring liability was not significant.
