Business Acquisition [Line Items] |
Acquisition of Inotera | Acquisition of Inotera Through December 6, 2016, we held a 33% ownership interest in Inotera, now known as MTTW, Nanya and certain of its affiliates held a 32% ownership interest, and the remaining ownership interest was publicly held. On December 6, 2016, we acquired the 67% remaining interest in Inotera not owned by us (the "Inotera Acquisition") and began consolidating Inotera's operating results. The cash paid for the Inotera Acquisition was funded, in part, with proceeds from the 2021 MSTW Term Loan and the sale of the Micron Shares (as defined below) to Nanya. Inotera manufactures DRAM products at its 300mm wafer fabrication facility in Taoyuan City, Taiwan, and previously sold such products exclusively to us through supply agreements. SG&A expenses for 2017 and 2016 included transaction costs of $13 million and $3 million, respectively, incurred in connection with the Inotera Acquisition. In connection with the Inotera Acquisition, we revalued our previously-held 33% equity interest to its fair value. In determining the fair value, we used various valuation techniques, including the share price of Inotera prior to the announcement of the Inotera Acquisition and discounted cash flow projections using inputs including discount rate and terminal growth rate (Level 3). As a result, we recognized a non-operating gain of $71 million in 2017. In connection with the Inotera Acquisition, we sold 58 million shares of our common stock to Nanya (the "Micron Shares") and received cash proceeds of $986 million. Because the sale of the Micron Shares to Nanya was contemporaneous with, and contingent upon, the closing of the Inotera Acquisition, the issuance of the Micron Shares was treated in purchase accounting as a non-cash exchange for a portion of the shares of Inotera held by Nanya. The Micron Shares were issued in a transaction exempt from the registration requirements of the Securities Act of 1933, as amended, and were subject to certain restrictions on transfers at the time of sale. To reflect the lack of transferability, the fair value of the Micron Shares (based on the trading price of our common stock on the acquisition date) was reduced by a discount of $81 million, based on the implied volatility derived from traded options on our stock and on the duration of the lack of transferability (Level 2). The allocation of purchase price to assets acquired and liabilities assumed of Inotera was as follows:
Consideration |  |
Cash paid for Inotera Acquisition |  | $ | 4,099 |
Less cash received from sale of Micron Shares |  | (986 | )
Net cash paid for Inotera Acquisition |  | 3,113 |

The Inotera Acquisition enhances our flexibility to drive new technology, optimize the deployment of capital, and adapt our product offerings to changes in market conditions. As a result of these synergies, we allocated goodwill of $829 million, $198 million, and $97 million to CNBU, MBU, and EBU, respectively. Goodwill resulting from the Inotera Acquisition is not deductible for Taiwan corporate income tax purposes; however, it is deductible for Taiwan surtax purposes.

Technology Transfer and License Agreements with Nanya Effective December 6, 2016, the terms of technology transfer and license agreements provided Nanya with options to require us to transfer to Nanya certain technology for Nanya's use and deliverables related to the next DRAM process node generation after our 20nm process node (the "1X Process Node") and the next DRAM process node generation after the 1X Process Node (the "1Y Process Node"). Nanya's option for the 1X Process Node expired unexercised. If Nanya exercises its right for the 1Y Process Node, Nanya would pay us royalties for a license to the transferred 1Y Process Node technology based on revenues from products utilizing the technology, subject to specified caps, and we would also receive an equity interest in Nanya upon the achievement of certain milestones.
