Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying consolidated financial statements include the accounts of Micron and our consolidated subsidiaries and have been prepared in accordance with accounting principles generally accepted in the United States of America consistent in all material respects with those applied in our Annual Report on Form 10-K for the year ended August 31, 2017. In the opinion of our management, the accompanying unaudited consolidated financial statements contain all necessary adjustments, consisting of a normal recurring nature, to fairly state the financial information set forth herein. Certain reclassifications have been made to prior period amounts to conform to current period presentation. Our fiscal year is the 52 or 53-week period ending on the Thursday closest to August 31. Fiscal years 2018 and 2017 each contain 52 weeks. All period references are to our fiscal periods unless otherwise indicated. These interim financial statements should be read in conjunction with the consolidated financial statements and accompanying notes included in our Annual Report on Form 10-K for the year ended August 31, 2017.

Variable Interest Entities

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Variable Interest Entities	Variable Interest Entities We have interests in entities that are VIEs. If we are the primary beneficiary of a VIE, we are required to consolidate it. To determine if we are the primary beneficiary, we evaluate whether we have the power to direct the activities that most significantly impact the VIE's economic performance and the obligation to absorb losses or the right to receive benefits of the VIE that could potentially be significant to the VIE. Our evaluation includes identification of significant activities and an assessment of our ability to direct those activities based on governance provisions and arrangements to provide or receive product and process technology, product supply, operations services, equity funding, financing, and other applicable agreements and circumstances. Our assessments of whether we are the primary beneficiary of our VIEs require significant assumptions and judgments. Unconsolidated VIE PTI Xi'an : Powertech Technology Inc. Xi'an ("PTI Xi'an") is a wholly-owned subsidiary of Powertech Technology Inc. ("PTI") and was created to provide assembly services to us at our manufacturing site in Xi'an, China. We do not have an equity interest in PTI Xi'an. PTI Xi'an is a VIE because of the terms of its service agreement with us and its dependency on PTI to finance its operations. We have determined that we do not have the power to direct the activities of PTI Xi'an that most significantly impact its economic performance, primarily because we have no governance rights. Therefore, we do not consolidate PTI Xi'an. In connection therewith, we had capital lease obligations and net property, plant, and equipment of $84 million and $81 million , respectively, as of November 30, 2017 , and $80 million and $76 million , respectively, as of August 31, 2017 . Consolidated VIE IMFT : IMFT is a VIE because all of its costs are passed to us and its other member, Intel, through product purchase agreements and because IMFT is dependent upon us or Intel for additional cash requirements. The primary activities of IMFT are driven by the constant introduction of product and process technology. Because we perform a significant majority of the technology development, we have the power to direct its key activities. We consolidate IMFT because we have the power to direct the activities of IMFT that most significantly impact its economic performance and because we have the obligation to absorb losses and the right to receive benefits from IMFT that could potentially be significant to it. (See "Equity – Noncontrolling Interests in Subsidiaries – IMFT" note.)

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recently Issued Accounting Standards	Recently Issued Accounting Standards In October 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2016-16 – Intra-Entity Transfers Other Than Inventory , which requires an entity to recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. This ASU will be effective for us in the first quarter of 2019 and requires modified retrospective adoption. We are evaluating the effects of our adoption of this ASU on our financial statements. In June 2016, the FASB issued ASU 2016-13 – Measurement of Credit Losses on Financial Instruments , which requires a financial asset (or a group of financial assets) measured on the basis of amortized cost to be presented at the net amount expected to be collected. This ASU requires that the income statement reflect the measurement of credit losses for newly recognized financial assets as well as the expected increases or decreases of expected credit losses that have taken place during the period. This ASU requires that credit losses of debt securities designated as available-for-sale be recorded through an allowance for credit losses and limits the credit loss to the amount by which fair value is below amortized cost. This ASU will be effective for us in the first quarter of 2021 with adoption permitted as early as the first quarter of 2020. This ASU requires modified retrospective adoption, with prospective adoption for debt securities for which an other-than-temporary impairment had been recognized before the effective date. We are evaluating the timing and effects of our adoption of this ASU on our financial statements. In February 2016, the FASB issued ASU 2016-02 – Leases , which amends a number of aspects of lease accounting, including requiring lessees to recognize operating leases with a term greater than one year on their balance sheet as a right-of- use asset and corresponding liability, measured at the present value of the lease payments. This ASU will be effective for us in the first quarter of 2020 with early adoption permitted and requires modified retrospective adoption. The adoption of this ASU will result in an increase in right-of-use assets and corresponding liabilities. We are evaluating the timing and other effects of our adoption of this ASU on our financial statements. In January 2016, the FASB issued ASU 2016-01 – Recognition and Measurement of Financial Assets and Financial Liabilities , which provides guidance for the recognition, measurement, presentation, and disclosure of financial assets and liabilities. This ASU will be effective for us in the first quarter of 2019 and requires modified retrospective adoption. We are evaluating the effects of our adoption of this ASU on our financial statements. In May 2014, the FASB issued ASU 2014-09 – Revenue from Contracts with Customers , which supersedes nearly all existing revenue recognition guidance under generally accepted accounting principles in the United States. The core principal of this ASU, as amended, is that an entity should recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This ASU also requires additional disclosure about the nature, amount, timing, and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments, and assets recognized from costs incurred to obtain or fulfill a contract. This ASU will be effective for us in the first quarter of 2019 and allows for either full retrospective or modified retrospective adoption. We expect that, as a result of the adoption of this ASU, the timing of recognizing revenue from sales of products to our distributors under agreements allowing rights of return or price protection will be generally earlier than under the existing revenue recognition guidance. Revenue recognized upon resale by our customers under these arrangements was 22% and 23% of our consolidated revenue for the first quarters of 2018 and 2017 , respectively. After adoption, the impact of this change in any reporting period would be the net effect of changes to revenue recognized as of the beginning and end of each period. We are evaluating the method and other effects of our adoption of this ASU on our financial statements.

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 Micron Technology Taiwan, Inc. ("MTTW") and accounted for our ownership interest under the equity method. On December 6, 2016, we acquired the remaining 67% ownership interest in Inotera not owned by us (the "Inotera Acquisition") and began consolidating Inotera's operating results. 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, under which we purchased $504 million of DRAM products in the first quarter of 2017, based on a pricing formula that equally shared margin between Inotera and us. Pro Forma Financial Information The following pro forma financial information presents the combined results of operations as if the Inotera Acquisition had occurred on September 4, 2015. The pro forma financial information includes the accounting effects of the business combination, including adjustments for depreciation of property, plant, and equipment, interest expense, elimination of intercompany activities, and revaluation of inventories. The pro forma financial information below is not necessarily indicative of either future results of operations or results that might have been achieved had the Inotera Acquisition occurred on September 4, 2015.

(2) The fair value of Level 1 securities is measured based on quoted prices in active markets for identical assets. (3) The fair value of Level 2 securities is measured using information obtained from pricing services, which obtain quoted market prices for similar instruments, non-binding market consensus prices that are corroborated by observable market data, or various other methodologies, to determine the appropriate value at the measurement date. We perform supplemental analyses to validate information obtained from these pricing services. No adjustments were made to the fair values indicated by such pricing information as of November 30, 2017 or August 31, 2017. (4) Restricted cash is included in other noncurrent assets and primarily represents balances related to the MMJ Creditor Payments and interest reserve balances related to the 2021 MSTW Term Loan. Gross realized gains and losses from sales of available-for-sale securities were not material for any period presented. As of November 30, 2017 , there were no available-for-sale securities that had been in a loss position for longer than 12 months.

The 2033 Notes were classified as current because the terms of these notes require us to pay cash for the principal amount of any converted notes and holders of these notes had the right to convert their notes as of the dates presented. A portion of the 2032C Notes were classified as current because holders had converted the notes and they were not settled as of November 30, 2017. Debt Repurchases and Conversions During the first quarter of 2018, we repurchased or converted an aggregate of $2.36 billion principal amount of our debt. If we receive a notice of conversion for any of our convertible notes, and we elect to settle in cash any amount of the conversion obligation in excess of the principal amount, the cash settlement obligations become derivative debt liabilities subject to mark-to-market accounting treatment based on the volume-weighted-average price of our common stock over a period of 20 consecutive trading days. Accordingly, at the date of our election to settle a conversion in cash, we reclassify the fair value of the equity component of the converted notes from additional capital to derivative debt liability within current debt in our consolidated balance sheet. The following table presents the effects of repurchases and conversions of our debt in the first quarter of 2018: Quarter ended November 30, 2017 Decrease in Principal Increase (Decrease) in Carrying Value Decrease in Cash Decrease in Equity Gain (Loss) Repurchases 2023 Secured Notes (1) $ (1,250 ) $ (1,238 ) $ (1,373 ) $ — $ (135 ) 2023 Notes (2) (1,000 ) (991 ) (1,046 ) — (55 ) Conversions 2033E Notes (3) (105 ) (125 ) (216 ) (81 ) (10 ) 2032C Notes (4) — 186 — (191 ) 5 $ (2,355 ) $ (2,168 ) $ (2,635 ) $ (272 ) $ (195 ) (1) Redeemed $438 million of principal amount on November 13, 2017, which represented 35% of the original principal amount issued and was settled with proceeds from our common stock issuance in October 2017. Also redeemed the remaining $812 million of principal amount on November 16, 2017. (2) Redeemed on November 16, 2017. (3) In August 2017, holders converted an aggregate principal amount of $58 million , which were settled in the first quarter of 2018 for $92 million in cash and 3 million shares of our treasury stock. During the quarter ended November 30, 2017, holders converted an aggregate principal amount of $50 million . For converted notes with an aggregate principal amount of $20 million , we settled the principal amount of the conversion in the first quarter of 2018 with cash of $20 million and the remainder of the conversion amount was settled with 1 million shares of our treasury stock. For the remaining aggregate principal amount of $30 million of conversions in the first quarter of 2018, we elected to settle the conversion obligation in excess of the principal amount in cash. We paid $104 million in the first quarter of 2018 to settle obligations for $27 million of the aggregate principal amount and obligations for the remaining $3 million in principal will settle in the second quarter of 2018. (4) Holders converted an aggregate principal amount of $51 million and we elected to settle the conversion obligation in excess of the principal amount in cash. As a result, the carrying amount as of November 30, 2017 increased for the fair values of the derivative debt liability. The conversion of these notes will settle in the second quarter of 2018. IMFT Member Debt In November 2017, Intel provided debt financing (the "IMFT Member Debt") of $150 million to IMFT pursuant to the terms of the IMFT joint venture agreement. Pursuant to the IMFT joint venture agreement, the IMFT Member Debt bears no interest, matures upon the completion of the auction and the sale of assets of IMFT prior to the dissolution, liquidation, or other wind-up of IMFT, and is convertible, at the election of Intel, in whole or in part, into a capital contribution to IMFT. Upon conversion, the IMFT Member Debt would be added to IMFT's capital balance as a contribution from Intel. Additionally, to the extent IMFT distributes cash to its members under the terms of the IMFT joint venture agreement, Intel may, at its option, designate any portion of the distribution to be a repayment of the IMFT Member Debt, without penalty or premium. In the event Intel exercises its right to put its interest in IMFT to us, or if we exercise our right to call from Intel its interest in IMFT, Intel will transfer to Micron any IMFT Member Debt outstanding at the time of the closing of the put or call transaction. 2022 Senior Secured Term Loan B Repricing Amendment On October 26, 2017, we amended our 2022 Term Loan B, substantially all of which was treated as a debt modification, to reduce the interest rate margins. As of November 30, 2017 , the 2022 Term Loan B bears interest at LIBOR plus 2.00% . Convertible Senior Notes As of November 30, 2017 , the trading price of our common stock was higher than the initial conversion prices of our convertibles notes. As a result, the conversion values for these notes exceeded the principal amounts by $2.87 billion as of November 30, 2017 .

Loss Contingency [Abstract]
Contingencies	Contingencies We have accrued a liability and charged operations for the estimated costs of adjudication or settlement of various asserted and unasserted claims existing as of the balance sheet date, including those described below. We are currently a party to other legal actions arising from the normal course of business, none of which are expected to have a material adverse effect on our business, results of operations, or financial condition. Patent Matters As is typical in the semiconductor and other high-tech industries, from time to time, others have asserted, and may in the future assert, that our products or manufacturing processes infringe upon their intellectual property rights. On November 21, 2014, Elm 3DS Innovations, LLC ("Elm") filed a patent infringement action against Micron, MSP, and Micron Consumer Products Group, Inc. in the U.S. District Court for the District of Delaware. On March 27, 2015, Elm filed an amended complaint against the same entities. The amended complaint alleges that unspecified semiconductor products of ours that incorporate multiple stacked die infringe 13 U.S. patents and seeks damages, attorneys' fees, and costs. On December 15, 2014, Innovative Memory Solutions, Inc. filed a patent infringement action against Micron in the U.S. District Court for the District of Delaware. The complaint alleges that a variety of our NAND products infringe eight U.S. patents and seeks damages, attorneys' fees, and costs. On June 24, 2016, the President and Fellows of Harvard University filed a patent infringement action against Micron in the U.S. District Court for the District of Massachusetts. The complaint alleges that a variety of our DRAM products infringe two U.S. patents and seeks damages, injunctive relief, and other unspecified relief. Among other things, the above lawsuits pertain to certain of our DDR DRAM, DDR2 DRAM, DDR3 DRAM, DDR4 DRAM, SDR SDRAM, PSRAM, RLDRAM, LPDRAM, NAND, and certain other memory products we manufacture, which account for a significant portion of our net sales. We are unable to predict the outcome of assertions of infringement made against us and therefore cannot estimate the range of possible loss. A determination that our products or manufacturing processes infringe the intellectual property rights of others or entering into a license agreement covering such intellectual property could result in significant liability and/or require us to make material changes to our products and/or manufacturing processes. Any of the foregoing could have a material adverse effect on our business, results of operations, or financial condition. Qimonda On January 20, 2011, Dr. Michael Jaffé, administrator for Qimonda's insolvency proceedings, filed suit against Micron and Micron Semiconductor B.V., our Netherlands subsidiary ("Micron B.V."), in the District Court of Munich, Civil Chamber. The complaint seeks to void, under Section 133 of the German Insolvency Act, a share purchase agreement between Micron B.V. and Qimonda signed in fall 2008, pursuant to which Micron B.V. purchased substantially all of Qimonda's shares of Inotera (the "Inotera Shares"), representing approximately 18% of Inotera's outstanding shares as of November 30, 2017 , and seeks an order requiring us to re-transfer those shares to the Qimonda estate. The complaint also seeks, among other things, to recover damages for the alleged value of the joint venture relationship with Inotera and to terminate, under Sections 103 or 133 of the German Insolvency Code, a patent cross-license between us and Qimonda entered into at the same time as the share purchase agreement. Following a series of hearings with pleadings, arguments, and witnesses on behalf of the Qimonda estate, on March 13, 2014, the court issued judgments: (1) ordering Micron B.V. to pay approximately $1 million in respect of certain Inotera Shares sold in connection with the original share purchase; (2) ordering Micron B.V. to disclose certain information with respect to any Inotera Shares sold by it to third parties; (3) ordering Micron B.V. to disclose the benefits derived by it from ownership of the Inotera Shares, including in particular, any profits distributed on the Inotera Shares and all other benefits; (4) denying Qimonda's claims against Micron for any damages relating to the joint venture relationship with Inotera; and (5) determining that Qimonda's obligations under the patent cross-license agreement are canceled. In addition, the court issued interlocutory judgments ordering, among other things: (1) that Micron B.V. transfer to the Qimonda estate the Inotera Shares still owned by Micron B.V. and pay to the Qimonda estate compensation in an amount to be specified for any Inotera Shares sold to third parties; and (2) that Micron B.V. pay the Qimonda estate as compensation an amount to be specified for benefits derived by Micron B.V. from ownership of the Inotera Shares. The interlocutory judgments have no immediate, enforceable effect on us, and, accordingly, we expect to be able to continue to operate with full control of the Inotera Shares subject to further developments in the case. We have filed a notice of appeal, and the parties have submitted briefs to the appeals court. We are unable to predict the outcome of the matter and therefore cannot estimate the range of possible loss. The final resolution of this lawsuit could result in the loss of the Inotera Shares or monetary damages, unspecified damages based on the benefits derived by Micron B.V. from the ownership of the Inotera Shares, and/or the termination of the patent cross-license, which could have a material adverse effect on our business, results of operation, or financial condition. Other In the normal course of business, we are a party to a variety of agreements pursuant to which we may be obligated to indemnify the other party. It is not possible to predict the maximum potential amount of future payments under these types of agreements due to the conditional nature of our obligations and the unique facts and circumstances involved in each particular agreement. Historically, our payments under these types of agreements have not had a material adverse effect on our business, results of operations, or financial condition.

Equity [Abstract]
Equity	Equity Micron Shareholders' Equity Common Stock Issuance : In October 2017, we issued 34 million shares of our common stock for $41.00 per share in a public offering for proceeds of $1.36 billion , net of underwriting fees and other offering costs. Outstanding Capped Calls : In connection with certain of our convertible notes, we entered into capped call transactions, which are intended to reduce the effect of potential dilution. The capped calls provide for our receipt of cash or shares, at our election, from our counterparties if the trading price of our stock is above the strike prices on the expiration dates. As of November 30, 2017 , the dollar value of cash or shares that we would receive from our outstanding capped calls upon their expiration dates range from $0 , if the trading price of our stock is below the strike prices for all capped calls at expiration, to $527 million , if the trading price of our stock is at or above the cap prices for all capped calls. Settlement of the capped calls prior to the expiration dates may be for an amount less than the maximum value at expiration. Expiration of Capped Calls : Subsequent to the end of our first quarter of 2018, we share-settled expirations of portions of our capped calls, and received 5 million shares (equal to a value of $215 million ) based on the volume-weighted trading stock prices at the expiration dates. The shares received were recorded as treasury stock. Noncontrolling Interests in Subsidiaries As of November 30, 2017 August 31, 2017 Noncontrolling Interest Balance Noncontrolling Interest Percentage Noncontrolling Interest Balance Noncontrolling Interest Percentage IMFT $ 850 49 % $ 832 49 % Other 17 Various 17 Various $ 867 $ 849 IMFT : Since 2006, we have owned 51% of IMFT, a joint venture between us and Intel to manufacture semiconductor products exclusively for its members, who share the output of IMFT generally in proportion to their investment under a long-term supply agreement at prices approximating cost. For the first quarters of 2018 and 2017 , sales to Intel under such agreements were $112 million and $110 million , respectively. In the first quarter of 2018, IMFT discontinued production of NAND and continues to ramp production of 3D XPoint products. IMFT is governed by a Board of Managers, for which the number of managers appointed by each member varies based on the members' respective ownership interests. The IMFT joint venture agreement extends through 2024 and includes certain buy-sell rights. At any time through December 2018, Intel can put to us, and from January 2019 through December 2021, we can call from Intel, Intel's interest in IMFT, in either case, for approximately the net book value of Intel's noncontrolling interest balance at the time of the closing. If Intel exercises its put right, we can elect to set the closing date of the transaction any time between six months and two years following such election by Intel and can elect to receive financing of the purchase price from Intel for one to two years from the closing date. If we exercise our call right, Intel can elect to set the closing date of the transaction to be any time between six months and one year following such election. Following the closing of either the put or the call, we will continue to supply to Intel for a period of one year, at Intel's choice, between 50% and 100% of Intel's immediately preceding six -month period pre-closing volumes of IMFT products for the first six -month period following the closing and, at Intel's choice, between 0% and 100% of Intel's first six -month period following the closing volumes of IMFT products for the second six -month period following the closing, at a margin that varies depending on whether the put or call was exercised. As of November 30, 2017, IMFT had $150 million of IMFT Member Debt outstanding from Intel. Creditors of IMFT have recourse only to IMFT's assets and do not have recourse to any other of our assets. The following table presents the assets and liabilities of IMFT included in our consolidated balance sheets: As of November 30, August 31, Assets Cash and equivalents $ 117 $ 87 Receivables 79 81 Inventories 106 128 Other current assets 4 7 Total current assets 306 303 Property, plant, and equipment, net 2,075 1,852 Other noncurrent assets 49 49 Total assets $ 2,430 $ 2,204 Liabilities Accounts payable and accrued expenses $ 351 $ 299 Deferred income 8 6 Current debt 19 19 Total current liabilities 378 324 Long-term debt 220 75 Other noncurrent liabilities 82 88 Total liabilities $ 680 $ 487 Amounts exclude intercompany balances that were eliminated in our consolidated balance sheets. Restrictions on Net Assets As a result of the corporate reorganization proceedings of MMJ, the 2021 MSTW Term Loan covenants, and the IMFT joint venture agreement, our total restricted net assets (excluding intercompany balances and noncontrolling interests) as of November 30, 2017 were $3.71 billion for the MMJ Group, $2.35 billion for MSTW and MTTW, and $899 million for IMFT.

The fair values of our other debt instruments were estimated based on Level 2 inputs, including discounted cash flows, including the trading price of our notes, when available, and interest rates based on similar debt issued by parties with credit ratings similar to ours.

Derivative Instruments

Derivative Instrument Detail [Abstract]
Derivative Instruments	Derivative Instruments We use derivative instruments to manage our exposure to changes in currency exchange rates from our monetary assets and liabilities denominated in currencies other than the U.S. dollar. We do not use derivative instruments for speculative purpose. Derivative Instruments without Hedge Accounting Designation Currency Derivatives : To hedge our exposures of monetary assets and liabilities to changes in currency exchange rates, we generally utilize a rolling hedge strategy with currency forward contracts that mature within nine months. In addition, to mitigate the risk of the yen strengthening against the U.S. dollar with respect to our MMJ Creditor Payments due in December 2017 and 2018, as of November 30, 2017, we had forward contracts to purchase 18 billion yen in December 2017 and 28 billion yen in December 2018. At the end of each reporting period, monetary assets and liabilities denominated in currencies other than the U.S. dollar are remeasured into U.S. dollars and the associated outstanding forward contracts are marked to market. Currency forward contracts are valued at fair values based on the middle of bid and ask prices of dealers or exchange quotations (Level 2). Convertible Notes Settlement Obligations : For settlement obligations associated with our convertible notes that become derivative debt liabilities subject to mark-to-market accounting treatment, the fair values of the underlying derivative settlement obligations were initially determined using the Black-Scholes option valuation model (Level 2), which requires inputs of stock price, expected stock-price volatility, estimated option life, risk-free interest rate, and dividend rate. The subsequent measurement amounts of our convertible note settlement obligations were based on the volume-weighted-average stock price (Level 2). Changes in fair values of the derivative settlement obligations were included in other non-operating income (expense), net. Total notional amounts and gross fair values for derivative instruments without hedge accounting designation were as follows: Notional Amount (1) Fair Value of Current Assets (2) Current Liabilities (3) Noncurrent Assets (4) Noncurrent Liabilities (5) As of November 30, 2017 Currency forward contracts New Taiwan dollar $ 3,388 $ 31 $ (2 ) $ — $ — Yen 1,733 5 (4 ) — (4 ) Singapore dollar 570 2 — — — Euro 210 1 — — — Other 47 — (1 ) — — $ 5,948 Convertible notes settlement obligation 6 — (249 ) — — $ 39 $ (256 ) $ — $ (4 ) As of August 31, 2017 Currency forward contracts New Taiwan dollar $ 2,921 $ 22 $ (2 ) $ — $ — Yen 1,209 5 — 1 — Singapore dollar 324 1 — — — Euro 368 5 (2 ) — — Other 25 1 (1 ) — — $ 4,847 Convertible notes settlement obligation 2 — (47 ) — — $ 34 $ (52 ) $ 1 $ — (1) Notional amounts of forward contracts in U.S. dollars and convertible notes settlement obligations in shares. (2) Included in receivables – other. (3) Included in accounts payable and accrued expenses – other for forward contracts and in current debt for convertible notes settlement obligations. (4) Included in other noncurrent assets. (5) Included in other noncurrent liabilities. Realized and unrealized gains and losses on derivative instruments without hedge accounting designation as well as the changes in the underlying monetary assets and liabilities due to changes in currency exchange rates are included in other non-operating income (expense). For derivative instruments without hedge accounting designation, recognized losses were $2 million and $178 million for the first quarters of 2018 and 2017 , respectively. Derivative Instruments with Cash Flow Hedge Accounting Designation Currency Derivatives : We utilize currency forward contracts that generally mature within 12 months to hedge our exposure to changes in cash flows from changes in currency exchange rates for certain capital expenditures. Currency forward contracts are measured at fair value based on market-based observable inputs including currency exchange spot and forward rates, interest rates, and credit-risk spreads (Level 2). For derivative instruments designated as cash flow hedges, the effective portion of the realized and unrealized gain or loss on the derivatives is included as a component of accumulated other comprehensive income (loss). Amounts in accumulated other comprehensive income (loss) are reclassified into earnings in the same line items and in the same periods in which the underlying transactions affect earnings. The ineffective and excluded portion of the realized and unrealized gain or loss is included in other non-operating income (expense). Total notional amounts and gross fair values for derivative instruments with cash flow hedge accounting designation were as follows: Notional Amount (in U.S. Dollars) Fair Value Current Assets (1) Current Liabilities (2) As of November 30, 2017 Euro $ 310 $ 5 $ — Yen 254 1 (3 ) $ 564 $ 6 $ (3 ) As of August 31, 2017 Euro $ 198 $ 13 $ — Yen 258 4 — $ 456 $ 17 $ — (1) Included in receivables – other. (2) Included in accounts payable and accrued expenses – other. We recognized losses of $4 million and $9 million for the first quarters of 2018 and 2017 , respectively, in accumulated other comprehensive income from the effective portion of cash flow hedges. Neither the ineffective portions of cash flow hedges recognized in other non-operating income (expense) nor the reclassifications from accumulated other comprehensive income (loss) to earnings were material in the first quarters of 2018 and 2017 . The amounts from cash flow hedges included in accumulated other comprehensive income (loss) that are expected to be reclassified into earnings in the next 12 months were also not material.

Income Taxes	Income Taxes Our income tax (provision) benefit consisted of the following: Quarter ended November 30, 2017 December 1, 2016 Utilization of and other changes in net deferred tax assets of MMJ, MMT, and MTTW $ (26 ) $ (13 ) Other income tax (provision) benefit, primarily other non-U.S. operations (88 ) (18 ) $ (114 ) $ (31 ) We have a full valuation allowance for our net deferred tax asset associated with our U.S. operations. The amount of the deferred tax asset considered realizable could be adjusted if significant positive evidence increases. Income taxes on U.S. operations in the first quarters of 2018 and 2017 were substantially offset by changes in the valuation allowance. We operate in a number of tax jurisdictions, including Singapore and Taiwan, where our earnings are indefinitely reinvested and are taxed at lower tax rates than the U.S. statutory rate and in a number of locations outside the United States, including Singapore, where we have tax incentive arrangements that are conditional, in part, upon meeting certain business operations and employment thresholds. The effect of tax incentive arrangements, which expire in whole or in part at various dates through 2030, reduced our tax provision by $391 million (benefitting our diluted earnings per share by $0.32 ) for the first quarter of 2018 and by $40 million ( $0.04 per diluted share) for the first quarter of 2017 . U.S. tax reform legislation, if enacted on terms similar to current proposals, could reduce the U.S. corporate income tax rate and significantly affect how income from foreign operations is taxed in the United States. U.S. tax reform could subject a significant portion of cumulative and future foreign earnings to U.S. income taxes. We will assess the impact of U.S. tax reform on the realizability of the net deferred tax assets of our U.S. operations, which as of August 31, 2017, were reduced by a full valuation allowance of $1.52 billion . In addition, the reduction of the U.S. corporate income tax rate could have the effect of reducing the value of certain of our deferred tax assets in the United States. U.S. tax reform may have an adverse effect on our provision for income taxes and could cause a significant increase in our cash tax liabilities in the near term. We have available net operating loss and tax credit carryforwards that may partially offset taxes that result from U.S. tax reform.

Variable Interest Entities	We have interests in entities that are VIEs. If we are the primary beneficiary of a VIE, we are required to consolidate it. To determine if we are the primary beneficiary, we evaluate whether we have the power to direct the activities that most significantly impact the VIE's economic performance and the obligation to absorb losses or the right to receive benefits of the VIE that could potentially be significant to the VIE. Our evaluation includes identification of significant activities and an assessment of our ability to direct those activities based on governance provisions and arrangements to provide or receive product and process technology, product supply, operations services, equity funding, financing, and other applicable agreements and circumstances. Our assessments of whether we are the primary beneficiary of our VIEs require significant assumptions and judgments.

[1]	Since the closing price of our common stock exceeded 130% of the conversion price per share for at least 20 trading days in the 30 trading day period ended on September 30, 2017, these notes are convertible by the holders through the calendar quarter ended December 31, 2017. The 2033 Notes were classified as current because the terms of these notes require us to pay cash for the principal amount of any converted notes and holders of these notes had the right to convert their notes as of the dates presented. A portion of the 2032C Notes were classified as current because holders had converted the notes and they were not settled as of November 30, 2017.

[1]	Redeemed $438 million of principal amount on November 13, 2017, which represented 35% of the original principal amount issued and was settled with proceeds from our common stock issuance in October 2017. Also redeemed the remaining $812 million of principal amount on November 16, 2017.
[2]	Redeemed on November 16, 2017.
[3]	In August 2017, holders converted an aggregate principal amount of $58 million, which were settled in the first quarter of 2018 for $92 million in cash and 3 million shares of our treasury stock. During the quarter ended November 30, 2017, holders converted an aggregate principal amount of $50 million. For converted notes with an aggregate principal amount of $20 million, we settled the principal amount of the conversion in the first quarter of 2018 with cash of $20 million and the remainder of the conversion amount was settled with 1 million shares of our treasury stock. For the remaining aggregate principal amount of $30 million of conversions in the first quarter of 2018, we elected to settle the conversion obligation in excess of the principal amount in cash. We paid $104 million in the first quarter of 2018 to settle obligations for $27 million of the aggregate principal amount and obligations for the remaining $3 million in principal will settle in the second quarter of 2018.
[4]	Holders converted an aggregate principal amount of $51 million and we elected to settle the conversion obligation in excess of the principal amount in cash. As a result, the carrying amount as of November 30, 2017 increased for the fair values of the derivative debt liability. The conversion of these notes will settle in the second quarter of 2018.
