Income Tax Disclosure [Abstract]
INCOME TAXES	NOTE H – INCOME TAXES Our effective tax rate from continuing operations was (60.3) percent for the second quarter of 2017 as compared to 47.8 percent for the second quarter of 2016. For the first half of 2017, our effective tax rate from continuing operations was (10.1) percent, as compared to 97.0 percent for the first half of 2016. The change in our reported tax rates for the second quarter and first half of 2017, as compared to the same periods in 2016, relates primarily to the impact of certain receipts and charges that are taxed at different rates than our effective tax rate, including acquisition-related items, contingent consideration, restructuring and restructuring-related items, investment impairment-related items, litigation-related items and amortization expense, as well as the impact of certain discrete tax items. As of June 30, 2017, we had $1.116 billion of gross unrecognized tax benefits, of which a net $1.027 billion, if recognized, would affect our effective tax rate. As of December 31, 2016, we had $1.095 billion of gross unrecognized tax benefits, of which a net $1.006 billion, if recognized, would affect our effective tax rate. We have received Notices of Deficiency from the Internal Revenue Service (IRS) reflecting proposed audit adjustments for Guidant Corporation for its 2001 through 2006 tax years and for Boston Scientific Corporation for its 2006 and 2007 tax years. The total incremental tax liability asserted by the IRS for the applicable periods is $1.162 billion plus interest. The primary issue in dispute for all years is the transfer pricing associated with the technology license agreements between domestic and foreign subsidiaries of Guidant. In addition, the IRS has proposed adjustments in connection with the financial terms of our Transaction Agreement with Abbott Laboratories pertaining to the sale of Guidant's vascular intervention business to Abbott in April 2006. During 2014, we received a Revenue Agent Report from the IRS reflecting significant proposed audit adjustments to our 2008, 2009 and 2010 tax years based upon the same transfer pricing methodologies that the IRS applied to our 2001 through 2007 tax years. We do not agree with the transfer pricing methodologies applied by the IRS or its resulting assessment. We have filed petitions with the U.S. Tax Court (Tax Court) contesting the Notices of Deficiency for the 2001 through 2007 tax years in challenge and submitted a letter to the IRS Office of Appeals (IRS Appeals) protesting the Revenue Agent Report for the 2008 through 2010 tax years and requesting an administrative appeal hearing. The issues in dispute were scheduled to be heard in Tax Court in late July 2016. On July 19, 2016, we entered into a Stipulation of Settled Issues with the IRS intended to resolve all of the aforementioned transfer pricing issues, as well as the issues related to our transaction with Abbott, for the 2001 through 2007 tax years. The Stipulation of Settled Issues is contingent upon IRS Office of Appeals applying the same basis of settlement to all transfer pricing issues for the Company’s 2008, 2009 and 2010 tax years and if applicable, review by the United States Congress Joint Committee on Taxation. In October 2016, we reached an agreement in principle with the IRS Appeals as to the resolution of transfer pricing issues in 2008, 2009 and 2010 tax years, subject to additional calculations of tax as well as documentation to memorialize our agreement. In the event that the conditions in the Stipulation of Settled Items are satisfied, we expect to make net tax payments of approximately $275 million, plus interest, through the date of payment. If finalized, payments related to the resolution are expected in the next three to nine months. We believe that our income tax reserves associated with these matters are adequate as of June 30, 2017 and we do not expect to recognize any additional charges related to the resolution of this controversy. However, the final resolution of these issues is contingent and if the Stipulation of Settled Issues is not finalized, it could have a material impact on our financial condition, results of operations, or cash flows. We recognize interest and penalties related to income taxes as a component of income tax expense. We had $612 million accrued for gross interest and penalties as of June 30, 2017 and $572 million as of December 31, 2016. We recognized net tax expense related to interest and penalties of $13 million during the second quarter of 2017 and the second quarter of 2016, $26 million during the first half of 2017 and $23 million during the first half of 2016. It is reasonably possible that within the next 12 months we will resolve multiple issues including transfer pricing and transactional-related issues with foreign, federal and state taxing authorities, in which case we could record a reduction in our balance of unrecognized tax benefits of up to approximately $757 million.
