Income Taxes	3 Months Ended
Mar. 31, 2017
Income Tax Disclosure [Abstract]
INCOME TAXES	NOTE H – INCOME TAXES Our effective tax rates from continuing operations were 4.9% for the three months ended March 31, 2017 and 11.4% for the three months ended March 31, 2016. The change in our reported tax rate for the first quarter of 2017, as compared to the same period 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, litigation-related items and amortization expense, as well as the impact of certain discrete tax items. During the first quarter of 2017, we recorded a discrete tax benefit related to share-based payment awards due to application of ASC Update No. 2016-09. Refer to Note M – New Accounting Pronouncements to our unaudited condensed consolidated financial statements contained in Item 1 of this Quarterly Report on Form 10-Q for additional information. As of March 31, 2017, we had $1.106 billion of gross unrecognized tax benefits, of which a net $1.017 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. The Stipulation of Settled Issues is contingent upon IRS 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 U.S. 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 to the IRS of approximately $275 million, plus interest through the date of payment. If finalized, payments related to the resolution are expected in the next six to 12 months. We believe that our income tax reserves associated with these matters are adequate as of March 31, 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 $592 million accrued for gross interest and penalties as of March 31, 2017 and $572 million as of December 31, 2016. We recognized net tax expense related to interest and penalties of $13 million during the first quarter of 2017 and $10 million during the first quarter 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.
