Acquisitions, Divestitures and Licensing Arrangements [Text Block]	ACQUISITIONS, DIVESTITURES AND LICENSING ARRANGEMENTS Acquisitions IFM In the third quarter of 2017, BMS acquired all of the outstanding shares of IFM, a private biotechnology company focused on developing therapies that modulate novel targets in the innate immune system to treat cancer, autoimmunity and inflammatory diseases. The acquisition provides BMS with full rights to IFM's preclinical STING and NLRP3 agonist programs focused on enhancing the innate immune response for treating cancer. The consideration includes an upfront payment of $300 million and contingent development, regulatory and sales-based milestone payments of up to $1.0 billion for the first product from each of the two programs and additional contingent milestone payments of up to $555 million for any subsequent products from these programs. No significant IFM processes were acquired, therefore the transaction was accounted for as an asset acquisition because IFM was determined not to be a business as that term is defined in ASC 805 - Business Combinations. BMS also paid $25 million for certain negotiation rights to collaborate, license or acquire an NLRP3 antagonist program from a newly formed entity established by the former shareholders of IFM. The transactions resulted in $310 million of R&D expense and $15 million of deferred tax assets for net operating losses and tax credit carryforwards. Flexus In the second quarter of 2017, a $100 million milestone was achieved and paid to former stockholders of Flexus as additional contingent consideration following the commencement of a Phase II clinical study of an anti-cancer IDO inhibitor. The additional consideration was included in R&D expense as the Flexus acquisition in 2015 was accounted for as an asset acquisition. Cardioxyl In the second quarter of 2017, a $100 million milestone was achieved and paid to former stockholders of Cardioxyl as additional contingent consideration following the commencement of a Phase II clinical study of a cardiovascular Nitroxyl Donor. The additional consideration was included in R&D expense as the Cardioxyl acquisition in 2015 was accounted for as an asset acquisition. Divestitures SK Biotek In the second quarter of 2017, BMS agreed to sell its small molecule active pharmaceutical ingredient manufacturing operations in Swords, Ireland to SK Biotek. The divestiture includes the transfer of the facility, the majority of employees at the site, inventories and certain third-party contract manufacturing obligations. The purchase price is expected to be approximately $140 million subject to inventory levels on the date of closing. The transaction is expected to close in the fourth quarter of 2017 subject to SK Biotek's receipt of certain environmental permits and other customary closing conditions and will be accounted for as a sale of a business. Net assets of approximately $140 million were accounted for as held-for-sale as of September 30, 2017, consisting primarily of inventories and property, plant and equipment, and were included in prepaid expenses and other. The assets were reduced to their estimated relative fair value after considering the purchase price resulting in an impairment charge of $128 million that was included in cost of products sold in the nine months ended September 30, 2017. SK Biotek will provide certain manufacturing services for BMS through 2022. Revenues and pretax earnings related to this operation were not material in 2017 and 2016 (excluding the impairment charge). Licensing Arrangements Halozyme In the third quarter of 2017, BMS and Halozyme announced a global collaboration and license agreement to develop subcutaneously administered BMS IO medicines using Halozyme's ENHANZE* drug-delivery technology. This technology may allow for more rapid delivery of large volume injectable medications, such as medications that are currently delivered intravenously, through subcutaneous delivery. BMS agreed to pay $105 million to Halozyme for access to the technology which will be included in R&D expense in the fourth quarter of 2017. BMS has designated multiple IO targets, including PD-1, to develop using the ENHANZE* technology and has an option to select additional targets within five years from the effective date up to a maximum of 11 targets. BMS may pay up to $160 million upon achievement of contingent development, regulatory and sales-based milestone events for each of the nominated collaboration targets, additional milestone payments for combination products and future royalties on sales of products using the ENHANZE* technology. The agreement is subject to obtaining customary regulatory and antitrust approvals. CytomX In the second quarter of 2017, BMS expanded its strategic collaboration with CytomX to discover novel therapies using CytomX’s proprietary Probody platform. As part of the original May 2014 collaboration to discover, develop and commercialize Probody therapeutics, BMS selected four oncology targets, including CTLA-4. Pursuant to the expanded agreement, CytomX will grant BMS exclusive worldwide rights to develop and commercialize Probody therapeutics for up to eight additional targets. BMS paid CytomX $75 million for the rights to the initial four targets which was expensed as R&D prior to 2017. BMS paid $200 million to CytomX for access to the additional targets which was included in R&D expense in the second quarter of 2017. BMS will also reimburse CytomX for certain research costs over the collaboration period, pay up to $448 million upon achievement of contingent development, regulatory and sales milestone events for each collaboration target and future royalties if a product is approved and commercialized. Biogen In the second quarter of 2017, BMS out-licensed to Biogen exclusive rights to develop and commercialize BMS-986168, an anti-eTau compound in development for Progressive Supranuclear Palsy. Biogen paid $300 million to BMS which was included in other income in the second quarter of 2017 as BMS has no further performance obligations as part of the agreement. BMS is also entitled to contingent development, regulatory and sales based milestone payments of up to $410 million if achieved as well as future royalties if the product is ultimately approved and commercialized. BMS originally acquired the rights to this compound in 2014 through its acquisition of iPierian. Biogen assumed all of BMS’s remaining obligations to the former stockholders of iPierian. Roche In the second quarter of 2017, BMS out-licensed to Roche exclusive rights to develop and commercialize BMS-986089, an anti-myostatin adnectin in development for Duchenne Muscular Dystrophy. Roche paid $170 million to BMS which was included in other income in the second quarter of 2017 as BMS has no further performance obligations as part of the agreement. BMS will also be entitled to contingent development and regulatory milestone payments of up to $205 million if achieved and future royalties if the product is ultimately approved and commercialized.
