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 will deliver value to patients and stockholders. These efforts include a restructuring, which is also delivering cost savings and funding investments. As part of the restructuring, we are closing or have closed our facilities in Washington state and Colorado and 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 June 30, 2016, we have incurred $471 million of separation and other headcount-related costs and $213 million of asset-related charges. We expect that we will incur most of the remaining estimated costs during the remainder of 2016 and in 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 six months ended June 30, 2016, were not significant. As of June 30, 2016, the total restructuring liability decreased to $35 million due primarily to payments related to separation costs.

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 will deliver value to patients and stockholders. These efforts include a restructuring, which is also delivering cost savings and funding investments. As part of the restructuring, we are closing or have closed our facilities in Washington state and Colorado and 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 June 30, 2016, we have incurred $471 million of separation and other headcount-related costs and $213 million of asset-related charges. We expect that we will incur most of the remaining estimated costs during the remainder of 2016 and in 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 six months ended June 30, 2016, were not significant. As of June 30, 2016, the total restructuring liability decreased to $35 million due primarily to payments related to separation costs.
