Accounting Policies [Abstract]
Summary of Significant Accounting Policies	NOTE 1 — Summary of Significant Accounting Policies Description of Business NIKE, Inc. is a worldwide leader in the design, development and worldwide marketing and selling of athletic footwear, apparel, equipment, accessories and services. NIKE, Inc. portfolio brands include the NIKE Brand, Jordan Brand, Hurley and Converse. The NIKE Brand is focused on performance athletic footwear, apparel, equipment, accessories and services across a wide range of sport categories, amplified with sport-inspired sportswear products carrying the Swoosh trademark, as well as other NIKE Brand trademarks. The Jordan Brand is focused on athletic and casual footwear, apparel and accessories using the Jumpman trademark. Sales and operating results of Jordan Brand products are reported within the respective NIKE Brand geographic operating segments. The Hurley brand is focused on surf and action sports and youth lifestyle footwear, apparel and accessories, using the Hurley trademark. Sales and operating results of Hurley brand products are reported within the NIKE Brand’s North America geographic operating segment. Converse designs, distributes, markets and sells casual sneakers, apparel and accessories under the Converse, Chuck Taylor, All Star, One Star, Star Chevron and Jack Purcell trademarks. In some markets outside the U.S., these trademarks are licensed to third parties who design, distribute, market and sell similar products. Operating results of the Converse brand are reported on a stand-alone basis. Basis of Consolidation The Consolidated Financial Statements include the accounts of NIKE, Inc. and its subsidiaries (the “Company”). All significant intercompany transactions and balances have been eliminated. On November 19, 2015, the Company announced a two -for-one split of both NIKE Class A and Class B Common Stock. The stock split was in the form of a 100 percent stock dividend payable on December 23, 2015 to shareholders of record at the close of business on December 9, 2015. Common stock began trading at the split-adjusted price on December 24, 2015. All share and per share amounts presented reflect the stock split. Reclassifications Certain prior year amounts have been reclassified to conform to fiscal 2018 presentation, including reclassified geographic operating segment data to reflect the changes in the Company’s operating structure, which became effective on June 1, 2017. Refer to Note 17 — Operating Segments and Related Information for additional information. During the fourth quarter of fiscal 2018, management identified a misstatement related to the historical allocation of repurchases of Class B Common stock between Capital in excess of stated value and Retained earnings . The Company assessed the materiality of these misstatements on prior period financial statements in accordance with U.S. Securities and Exchange Commission Staff Accounting Bulletin No. 99, Materiality, codified in ASC 250, Presentation of Financial Statements, and concluded that these misstatements were not material to any prior annual or interim period. As such, the Company has revised the Consolidated Balance Sheets as of May 31, 2017 , and has reduced Capital in excess of stated value by $2.9 billion and increased Retained earnings by the same amount. Within the Consolidated Statements of Shareholders’ Equity, the Company has made corresponding revisions of $2.6 billion , $0.1 billion and $0.2 billion for the periods ended May 31, 2015, 2016 and, 2017, respectively. Revenue Recognition Wholesale revenues are recognized when title and the risks and rewards of ownership have passed to the customer, based on the terms of sale. This occurs upon shipment or upon receipt by the customer depending on the country of the sale and the agreement with the customer. Retail store revenues are recorded at the time of sale and digital commerce revenues are recorded upon delivery to the customer. Amounts collected from customers for sales or value added tax are recorded on a net basis. Provisions for post-invoice sales discounts, returns and miscellaneous claims from customers are estimated and recorded as a reduction to revenue at the time of sale. Post-invoice sales discounts consist of contractual programs with certain customers or discretionary discounts expected to be granted to certain customers at a later date. Estimates of discretionary discounts, returns and claims are based on (1) historical rates, (2) specific identification of outstanding claims and outstanding returns not yet received from customers and (3) estimated discounts, returns and claims expected, but not yet finalized with customers. As of May 31, 2018 and 2017 , the Company’s reserve balances for post-invoice sales discounts, returns and miscellaneous claims were $675 million and $643 million , respectively. Cost of Sales Cost of sales consists primarily of inventory costs, as well as warehousing costs (including the cost of warehouse labor), third-party royalties, certain foreign currency hedge gains and losses and product design costs. Outbound shipping and handling costs are expensed as incurred and included in Cost of sales . Demand Creation Expense Demand creation expense consists of advertising and promotion costs, including costs of endorsement contracts, complimentary product, television, digital and print advertising and media costs, brand events and retail brand presentation. Advertising production costs are expensed the first time an advertisement is run. Advertising media costs are expensed when the advertisement appears. Costs related to brand events are expensed when the event occurs. Costs related to retail brand presentation are expensed when the presentation is complete and delivered. A significant amount of the Company’s promotional expenses result from payments under endorsement contracts. In general, endorsement payments are expensed on a straight-line basis over the term of the contract. However, certain contract elements may be accounted for differently based upon the facts and circumstances of each individual contract. Prepayments made under contracts are included in Prepaid expenses and other current assets or Deferred income taxes and other assets depending on the period to which the prepayment applies. Certain contracts provide for contingent payments to endorsers based upon specific achievements in their sports (e.g., winning a championship). The Company records Demand creation expense for these amounts when the endorser achieves the specific goal. Certain contracts provide for variable payments based upon endorsers maintaining a level of performance in their sport over an extended period of time (e.g., maintaining a specified ranking in a sport for a year). When the Company determines payments are probable, the amounts are reported in Demand creation expense ratably over the contract period based on the Company’s best estimate of the endorser’s performance. In these instances, to the extent actual payments to the endorser differ from the Company’s estimate due to changes in the endorser’s performance, adjustments to Demand creation expense may be recorded in a future period. Certain contracts provide for royalty payments to endorsers based upon a predetermined percent of sales of particular products. The Company expenses these payments in Cost of sales as the related sales occur. In certain contracts, the Company offers minimum guaranteed royalty payments. For contracts the Company estimates will not meet the minimum guaranteed amount of royalty fees through sales of product, the Company records the amount of the guaranteed payment in excess of that earned through sales of product in Demand creation expense uniformly over the contract period. Through cooperative advertising programs, the Company reimburses customers for certain costs of advertising the Company’s products. The Company records these costs in Demand creation expense at the point in time when it is obligated to its customers for the costs. This obligation may arise prior to the related advertisement being run. Total advertising and promotion expenses, which the Company refers to as Demand creation expense, were $3,577 million , $3,341 million and $3,278 million for the years ended May 31, 2018 , 2017 and 2016 , respectively. Prepaid advertising and promotion expenses totaled $730 million and $558 million at May 31, 2018 and 2017 , respectively, of which $359 million and $311 million , respectively, was recorded in Prepaid expenses and other current assets , and $371 million and $247 million , respectively, was recorded in Deferred income taxes and other assets, depending on the period to which the prepayment applies. Operating Overhead Expense Operating overhead expense consists primarily of wage and benefit-related expenses, research and development costs, as well as other administrative expenses, such as rent, depreciation and amortization, professional services, meetings and travel. Cash and Equivalents Cash and equivalents represent cash and short-term, highly liquid investments, that are both readily convertible to known amounts of cash, and so near their maturity they present insignificant risk of changes in value because of changes in interest rates, including commercial paper, U.S. Treasury, U.S. Agency, money market funds, time deposits and corporate debt securities with maturities of 90 days or less at the date of purchase. Short-Term Investments Short-term investments consist of highly liquid investments, including commercial paper, U.S. Treasury, U.S. Agency, time deposits and corporate debt securities, with maturities over 90 days at the date of purchase. Debt securities the Company has the ability and positive intent to hold to maturity are carried at amortized cost. At May 31, 2018 and 2017 , the Company did not hold any short-term investments classified as trading or held-to-maturity. At May 31, 2018 and 2017 , Short-term investments consisted of available-for-sale securities. Available-for-sale securities are recorded at fair value with unrealized gains and losses reported, net of tax, in Accumulated other comprehensive income , unless unrealized losses are determined to be other than temporary. Realized gains and losses on the sale of securities are determined by specific identification. The Company considers all available-for-sale securities, including those with maturity dates beyond 12 months, as available to support current operational liquidity needs and, therefore, classifies all securities with maturity dates beyond 90 days at the date of purchase as current assets within Short-term investments on the Consolidated Balance Sheets. Refer to Note 6 — Fair Value Measurements for more information on the Company’s short-term investments. Allowance for Uncollectible Accounts Receivable Accounts receivable, net consist primarily of amounts receivable from customers. The Company makes ongoing estimates relating to the collectability of its accounts receivable and maintains an allowance for estimated losses resulting from the inability of its customers to make required payments. In determining the amount of the allowance, the Company considers historical levels of credit losses and makes judgments about the creditworthiness of significant customers based on ongoing credit evaluations. Accounts receivable with anticipated collection dates greater than 12 months from the balance sheet date and related allowances are considered non-current and recorded in Deferred income taxes and other assets . The allowance for uncollectible accounts receivable was $30 million and $19 million at May 31, 2018 and 2017 , respectively. Inventory Valuation Inventories are stated at lower of cost and net realizable value, and valued on either an average or a specific identification cost basis. In some instances, we ship product directly from our supplier to the customer, with the related inventory and cost of sales recognized on a specific identification basis. Inventory costs primarily consist of product cost from the Company’s suppliers, as well as inbound freight, import duties, taxes, insurance and logistics and other handling fees. Property, Plant and Equipment and Depreciation Property, plant and equipment are recorded at cost. Depreciation is determined on a straight-line basis for land improvements, buildings and leasehold improvements over 2 to 40 years and for machinery and equipment over 2 to 15 years. Depreciation and amortization of assets used in manufacturing, warehousing and product distribution are recorded in Cost of sales . Depreciation and amortization of all other assets are recorded in Operating overhead expense . Software Development Costs Internal Use Software : Expenditures for major software purchases and software developed for internal use are capitalized and amortized over a 2 to 12 -year period on a straight-line basis. The Company’s policy provides for the capitalization of external direct costs of materials and services associated with developing or obtaining internal use computer software. In addition, the Company also capitalizes certain payroll and payroll-related costs for employees who are directly associated with internal use computer software projects. The amount of capitalizable payroll costs with respect to these employees is limited to the time directly spent on such projects. Costs associated with preliminary project stage activities, training, maintenance and all other post-implementation stage activities are expensed as incurred. Computer Software to be Sold, Leased or Otherwise Marketed : Development costs of computer software to be sold, leased or otherwise marketed as an integral part of a product are subject to capitalization beginning when a product’s technological feasibility has been established and ending when a product is available for general release to customers. In most instances, the Company’s products are released soon after technological feasibility has been established. Therefore, software development costs incurred subsequent to achievement of technological feasibility are usually not significant, and generally most software development costs have been expensed as incurred. Impairment of Long-Lived Assets The Company reviews the carrying value of long-lived assets or asset groups to be used in operations whenever events or changes in circumstances indicate the carrying amount of the assets might not be recoverable. Factors that would necessitate an impairment assessment include a significant adverse change in the extent or manner in which an asset is used, a significant adverse change in legal factors or the business climate that could affect the value of the asset or a significant decline in the observable market value of an asset, among others. If such facts indicate a potential impairment, the Company would assess the recoverability of an asset group by determining if the carrying value of the asset group exceeds the sum of the projected undiscounted cash flows expected to result from the use and eventual disposition of the assets over the remaining economic life of the primary asset in the asset group. If the recoverability test indicates that the carrying value of the asset group is not recoverable, the Company will estimate the fair value of the asset group using appropriate valuation methodologies, which would typically include an estimate of discounted cash flows. Any impairment would be measured as the difference between the asset group’s carrying amount and its estimated fair value. Goodwill and Indefinite-Lived Intangible Assets The Company performs annual impairment tests on goodwill and intangible assets with indefinite lives in the fourth quarter of each fiscal year or when events occur or circumstances change that would, more likely than not, reduce the fair value of a reporting unit or an intangible asset with an indefinite life below its carrying value. Events or changes in circumstances that may trigger interim impairment reviews include significant changes in business climate, operating results, planned investments in the reporting unit, planned divestitures or an expectation the carrying amount may not be recoverable, among other factors. The Company may first assess qualitative factors to determine whether it is more likely than not the fair value of a reporting unit is less than its carrying amount. If, after assessing the totality of events and circumstances, the Company determines it is more likely than not the fair value of the reporting unit is greater than its carrying amount, the two-step impairment test is unnecessary. The two-step impairment test first requires the Company to estimate the fair value of its reporting units. If the carrying value of a reporting unit exceeds its fair value, the goodwill of that reporting unit is potentially impaired and the Company proceeds to step two of the impairment analysis. In step two of the analysis, the Company measures and records an impairment loss equal to the excess of the carrying value of the reporting unit’s goodwill over its implied fair value, if any. Indefinite-lived intangible assets primarily consist of acquired trade names and trademarks. The Company may first perform a qualitative assessment to determine whether it is more likely than not an indefinite-lived intangible asset is impaired. If, after assessing the totality of events and circumstances, the C ompany determines it is more likely than not that the indefinite-lived intangible asset is not impaired, no quantitative fair value measurement is necessary. If a quantitative fair value measurement calculation is required for these intangible assets, the Company utilizes the relief-from-royalty method. This method assumes trade names and trademarks have value to the extent their owner is relieved of the obligation to pay royalties for the benefits received from them. This method requires the Company to estimate the future revenue for the related brands, the appropriate royalty rate and the weighted average cost of capital. Operating Leases The Company leases retail store space, certain distribution and warehouse facilities, office space, equipment and other non-real estate assets under operating leases. Operating lease agreements may contain rent escalation clauses, renewal options, rent holidays or certain landlord incentives, including tenant improvement allowances. Rent expense for non-cancelable operating leases with scheduled rent increases or landlord incentives are recognized on a straight-line basis over the lease term, beginning with the effective lease commencement date, which is generally the date in which the Company takes possession of or controls the physical use of the property. Certain leases also provide for contingent rent, which is generally determined as a percent of sales in excess of specified levels. A contingent rent liability is recognized together with the corresponding rent expense when specified levels have been achieved or when the Company determines that achieving the specified levels during the period is probable. Fair Value Measurements The Company measures certain financial assets and liabilities at fair value on a recurring basis, including derivatives and available-for-sale securities. Fair value is the price the Company would receive to sell an asset or pay to transfer a liability in an orderly transaction with a market participant at the measurement date. The Company uses a three-level hierarchy established by the Financial Accounting Standards Board (FASB) that prioritizes fair value measurements based on the types of inputs used for the various valuation techniques (market approach, income approach and cost approach). The levels of the fair value hierarchy are described below: • Level 1: Quoted prices in active markets for identical assets or liabilities. • Level 2: Inputs other than observable quoted prices for the asset or liability, either directly or indirectly; these include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active. • Level 3: Unobservable inputs with little or no market data available, which require the reporting entity to develop its own assumptions. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability. Financial assets and liabilities are classified in their entirety based on the most conservative level of input that is significant to the fair value measurement. Pricing vendors are utilized for a majority of Level 1 and Level 2 investments. These vendors either provide a quoted market price in an active market or use observable inputs without applying significant adjustments in their pricing. Observable inputs include broker quotes, interest rates and yield curves observable at commonly quoted intervals, volatilities and credit risks. The fair value of derivative contracts is determined using observable market inputs such as the daily market foreign currency rates, forward pricing curves, currency volatilities, currency correlations and interest rates and considers nonperformance risk of the Company and its counterparties. Level 1 investments include U.S. Treasury securities. Assets and liabilities included within Level 2 include commercial paper, U.S. Agency securities, money market funds, time deposits, corporate debt securities and derivative contracts. Level 3 investments are valued using internally developed models with unobservable inputs and are an immaterial portion of our portfolio. The Company’s fair value measurement process includes comparing fair values to another independent pricing vendor to ensure appropriate fair values are recorded. Refer to Note 6 — Fair Value Measurements for additional information. Foreign Currency Translation and Foreign Currency Transactions Adjustments resulting from translating foreign functional currency financial statements into U.S. Dollars are included in the foreign currency translation adjustment, a component of Accumulated other comprehensive income in Total shareholders’ equity . The Company’s global subsidiaries have various assets and liabilities, primarily receivables and payables, which are denominated in currencies other than their functional currency. These balance sheet items are subject to re-measurement, the impact of which is recorded in Other expense (income), net , within the Consolidated Statements of Income. Accounting for Derivatives and Hedging Activities The Company uses derivative financial instruments to reduce its exposure to changes in foreign currency exchange rates and interest rates. All derivatives are recorded at fair value on the Consolidated Balance Sheets and changes in the fair value of derivative financial instruments are either recognized in Accumulated other comprehensive income (a component of Total shareholders’ equity ), Long-term debt or Net income depending on the nature of the underlying exposure, whether the derivative is formally designated as a hedge and, if designated, the extent to which the hedge is effective. The Company classifies the cash flows at settlement from derivatives in the same category as the cash flows from the related hedged items. For undesignated hedges and designated cash flow hedges, this is primarily within the Cash provided by operations component of the Consolidated Statements of Cash Flows. For designated net investment hedges, this is within the Cash used by investing activities component of the Consolidated Statements of Cash Flows. For the Company’s fair value hedges, which are interest rate swaps used to mitigate the change in fair value of its fixed-rate debt attributable to changes in interest rates, the related cash flows from periodic interest payments are reflected within the Cash provided by operations component of the Consolidated Statements of Cash Flows. Refer to Note 16 — Risk Management and Derivatives for additional information on the Company’s risk management program and derivatives. Stock-Based Compensation The Company accounts for stock-based compensation by estimating the fair value of options and stock appreciation rights granted under the NIKE, Inc. Stock Incentive Plan and employees’ purchase rights under the employee stock purchase plans (ESPPs) using the Black-Scholes option pricing model. The Company recognizes this fair value as Cost of sales or Operating overhead expense , as applicable, in the Consolidated Statements of Income over the vesting period using the straight-line method. Refer to Note 11 — Common Stock and Stock-Based Compensation for additional information on the Company’s stock-based compensation programs. Income Taxes The Company accounts for income taxes using the asset and liability method. This approach requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the carrying amounts and the tax basis of assets and liabilities. The Company records a valuation allowance to reduce deferred tax assets to the amount management believes is more likely than not to be realized. The Company recognizes a tax benefit from uncertain tax positions in the financial statements only when it is more likely than not the position will be sustained upon examination by relevant tax authorities. The Company recognizes interest and penalties related to income tax matters in Income tax expense . Refer to Note 9 — Income Taxes for further discussion. Earnings Per Share Basic earnings per common share is calculated by dividing Net income by the weighted average number of common shares outstanding during the year. Diluted earnings per common share is calculated by adjusting weighted average outstanding shares, assuming conversion of all potentially dilutive stock options and awards. Refer to Note 12 — Earnings Per Share for further discussion. Management Estimates The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates, including estimates relating to assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates. Recently Adopted Accounting Standards In February 2018, the FASB issued Accounting Standards Update (ASU) No. 2018-02, Income Statement — Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income . The standard allows for reclassification of stranded tax effects on items resulting from the Tax Cuts and Jobs Act (the “Tax Act”) from Accumulated other comprehensive income to Retained earnings . Tax effects unrelated to the Tax Act are released from Accumulated other comprehensive income using either the specific identification approach or the portfolio approach based on the nature of the underlying item. The Company early adopted the ASU in the third quarter of fiscal 2018. As a result of the adoption, Retained earnings decreased by $17 million , with a corresponding increase to Accumulated other comprehensive income due to the reduction in the corporate tax rate from 35% to 21%. Refer to Note 9 — Income Taxes for additional information on the impact of the Tax Act. In March 2016, the FASB issued ASU No. 2016-09, Compensation — Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting , which changes how companies account for certain aspects of share-based payment awards to employees. The Company adopted the ASU in the first quarter of fiscal 2018. The updated guidance requires excess tax benefits and deficiencies from share-based payment awards to be recorded in income tax expense in the income statement. Previously, excess tax benefits and deficiencies were recognized in shareholders’ equity on the balance sheet. This change is required to be applied prospectively. As a result of the adoption, during fiscal 2018, the Company recognized $230 million of excess tax benefits related to share-based payment awards in Income tax expense in the Consolidated Statements of Income. Additionally, ASU 2016-09 modified the classification of certain share-based payment activities within the statement of cash flows, which the Company applied retrospectively. As a result, for fiscal 2017 and fiscal 2016, the Company reclassified cash inflows of $177 million and $281 million , respectively, related to excess tax benefits from share-based payment awards, from Cash used by financing activities to Cash provided by operations , and reclassified cash outflows of $29 million and $22 million , for the respective periods, related to tax payments for the net settlement of share-based payment awards, from Cash provided by operations to Cash used by financing activities within the Consolidated Statements of Cash Flows. Recently Issued Accounting Standards In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities , which expands and refines hedge accounting for both financial and non-financial risk components, aligns the recognition and presentation of the effects of hedging instruments and hedge items in the financial statements, and includes certain targeted improvements to ease the application of current guidance related to the assessment of hedge effectiveness. The update to the standard is effective for the Company on June 1, 2019, with early adoption permitted in any interim period. The Company is currently evaluating the updated guidance, but does not expect the adoption to have a material impact on the Consolidated Financial Statements. In October 2016, the FASB issued ASU No. 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory . The updated guidance requires companies to recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. Income tax effects of intra-entity transfers of inventory will continue to be deferred until the inventory has been sold to a third party. The Company will adopt the standard on June 1, 2018, using a modified retrospective approach, with the cumulative effect of applying the new standard recognized in retained earnings at the date of adoption. Upon adoption, the Company will record a cumulative effect adjustment reducing Retained earnings , Deferred income taxes and other assets , and Prepaid expenses and other current assets by $507 million , $422 million and $45 million , respectively, and increasing Deferred income taxes and other liabilities by $40 million . In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) , which replaces existing lease accounting guidance. The new standard is intended to provide enhanced transparency and comparability by requiring lessees to record right-of-use assets and corresponding lease liabilities on the balance sheet. The new guidance will require the Company to continue to classify leases as either operating or financing, with classification affecting the pattern of expense recognition in the income statement. The Company will adopt the standard on June 1, 2019. The ASU is required to be applied using a modified retrospective approach at the beginning of the earliest period presented, with optional practical expedients. The Company continues to assess the effect the guidance will have on its existing accounting policies and the Consolidated Financial Statements and expects there will be an increase in assets and liabilities on the Consolidated Balance Sheets at adoption due to the recording of right-of-use assets and corresponding lease liabilities, which may be material. Refer to Note 15 — Commitments and Contingencies for information about the Company’s lease obligations. In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments — Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities . The updated guidance enhances the reporting model for financial instruments, which includes amendments to address aspects of recognition, measurement, presentation and disclosure. The update to the standard is effective for the Company beginning June 1, 2018. The Company does not expect the adoption to have a material impact on the Consolidated Financial Statements. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Co

Under U.S. GAAP, accounting for the effect of tax legislation is required in the period of enactment. For fiscal 2018, the change in the corporate tax rate, effective January 1, 2018, results in a blended U.S. federal statutory rate for the Company of approximately 29% . The Tax Act also includes provisions not yet effective for the Company, including a provision to tax global intangible low-taxed income (GILTI) of foreign subsidiaries, which will be effective for the Company beginning June 1, 2018. In accordance with U.S. GAAP, the Company has made an accounting policy election to treat taxes due under the GILTI provision as a current period expense. A reconciliation from the U.S. statutory federal income tax rate to the effective income tax rate is as follows: Year Ended May 31, 2018 2017 2016 Federal income tax rate 29.2 % 35.0 % 35.0 % State taxes, net of federal benefit 1.2 % 1.1 % 1.1 % Foreign earnings -18.4 % -20.7 % -18.2 % Transition tax related to the Tax Act 43.3 % — % — % Remeasurement of deferred tax assets and liabilities related to the Tax Act 3.7 % — % — % Excess tax benefits from share-based compensation -5.3 % — % — % Resolution of a U.S. tax matter — % -3.2 % — % Other, net 1.6 % 1.0 % 0.8 % EFFECTIVE INCOME TAX RATE 55.3 % 13.2 % 18.7 % The effective tax rate for the year ended May 31, 2018 was higher than the effective tax rate for the year ended May 31, 2017 primarily due to the enactment of the Tax Act, which included provisional expense of $1,875 million for the one-time transition tax on the deemed repatriation of undistributed foreign earnings, and $158 million due to the remeasurement of deferred tax assets and liabilities. The remaining provisions of the Tax Act, which were a net benefit to the effective tax rate, did not have a material impact on the Company’s Consolidated Financial Statements during fiscal 2018. Additionally, the increase in the effective tax rate was partially offset by the tax benefit from share-based compensation in the current period as a result of the adoption of ASU 2016-09 in the first quarter of fiscal 2018. During the years ended May 31, 2017 and 2016, income tax benefits of $177 million and $281 million , respectively, attributable to employee share-based compensation were allocated to Total shareholders’ equity. As a result of the adoption of ASU 2016-09, beginning in fiscal 2018, income tax benefits from share-based compensation are reported in the Consolidated Statements of Income. The effective tax rate for the year ended May 31, 2017 was 550 basis points lower than the effective tax rate for the year ended May 31, 2016 primarily due to a one-time benefit in the first quarter of the fiscal year related to the resolution with the U.S. Internal Revenue Service (IRS) of a foreign tax credit matter and a decrease in foreign earnings taxed in the United States. In accordance with U.S. Securities and Exchange Commission Staff Accounting Bulletin No. 118 (“SAB 118”), the provisional amounts recorded represent reasonable estimates of the effects of the Tax Act for which the analysis is not yet complete. As the Company completes its analysis of the Tax Act, including collecting, preparing and analyzing necessary information, performing and refining calculations and obtaining additional guidance from the IRS, U.S. Treasury Department, FASB or other standard setting and regulatory bodies on the Tax Act, it may record adjustments to the provisional amounts, which may be material. In accordance with SAB 118, the Company’s accounting for the tax effects of the Tax Act will be completed during the measurement period, which should not extend beyond one year from the enactment date. At May 31, 2018, there were no provisions for which the Company was unable to record a reasonable estimate of the impact. Transition Tax During the third quarter of fiscal 2018, the Company recorded a provisional expense of $2,010 million related to the one-time transition tax on the deemed repatriation of undistributed foreign earnings. During the fourth quarter of fiscal 2018, as a result of further analysis of the provisions of the Tax Act and additional guidance, this provisional tax expense decreased by $135 million . The transition tax is based on the Company’s estimated total post-1986 undistributed foreign earnings at a tax rate of 15.5% for foreign cash and certain other specified assets, and 8% on the remaining earnings. The Company expects to pay the transition tax in installments over an eight -year period. Accordingly, the non-current portion of the provisional expense for the transition tax of $1,078 million , net of applicable foreign tax credits the Company expects to utilize, has been recorded in Deferred income taxes and other liabilities on the Consolidated Balance Sheets. Impact of Changes in the Tax Rate As a result of the reduction in the corporate tax rate from 35% to 21%, the Company remeasured certain deferred tax assets and liabilities based on the rates at which they are expected to be realized. The total provisional expense recorded during the period for the remeasurement of deferred tax assets and liabilities was $158 million . Deferred tax assets and liabilities comprise the following: As of May 31, (In millions) 2018 2017 Deferred tax assets: Inventories $ 73 $ 90 Sales return reserves 104 130 Deferred compensation 250 348 Stock-based compensation 135 225 Reserves and accrued liabilities 102 88 Net operating loss carry-forwards 88 84 Foreign tax credit carry-forwards — 208 Undistributed earnings of foreign subsidiaries — 173 Other 106 106 Total deferred tax assets 858 1,452 Valuation allowance (95 ) (82 ) Total deferred tax assets after valuation allowance 763 1,370 Deferred tax liabilities: Foreign withholding tax on undistributed earnings of foreign subsidiaries (155 ) — Property, plant and equipment (167 ) (254 ) Intangibles (77 ) (90 ) Other (26 ) (2 ) Total deferred tax liabilities (425 ) (346 ) NET DEFERRED TAX ASSET $ 338 $ 1,024 The following is a reconciliation of the changes in the gross balance of unrecognized tax benefits: As of May 31, (In millions) 2018 2017 2016 Unrecognized tax benefits, beginning of the period $ 461 $ 506 $ 438 Gross increases related to prior period tax positions 19 31 49 Gross decreases related to prior period tax positions (12 ) (163 ) (20 ) Gross increases related to current period tax positions 249 115 81 Settlements — (12 ) (13 ) Lapse of statute of limitations (20 ) (21 ) (17 ) Changes due to currency translation 1 5 (12 ) UNRECOGNIZED TAX BENEFITS, END OF THE PERIOD $ 698 $ 461 $ 506 As of May 31, 2018 , total gross unrecognized tax benefits, excluding related interest and penalties, were $698 million , $478 million of which would affect the Company’s effective tax rate if recognized in future periods. The Company recognizes interest and penalties related to income tax matters in Income tax expense . The liability for payment of interest and penalties decreased by $14 million during the year ended May 31, 2018 , decreased by $38 million during the year ended May 31, 2017 and increased by $45 million during the year ended May 31, 2016 . As of May 31, 2018 and 2017 , accrued interest and penalties related to uncertain tax positions were $157 million and $171 million , respectively (excluding federal benefit). The Company is subject to taxation in the United States, as well as various state and foreign jurisdictions. The Company has closed all U.S. federal income tax matters through fiscal 2014, with the exception of certain transfer pricing adjustments. The Company is currently under audit by the IRS for fiscal years 2015 and 2016. The Company’s major foreign jurisdictions, China and the Netherlands, have concluded substantially all income tax matters through calendar 2007 and fiscal 2012, respectively. Although the timing of resolution of audits is not certain, the Company evaluates all domestic and foreign audit issues in the aggregate, along with the expiration of applicable statutes of limitations, and estimates that it is reasonably possible the total gross unrecognized tax benefits could decrease by up to $163 million within the next 12 months. The Company historically provided for U.S. income taxes on the undistributed earnings of foreign subsidiaries unless they were considered indefinitely reinvested outside the United States. At May 31, 2017, the indefinitely reinvested earnings in foreign subsidiaries upon which United States income taxes had not been provided were approximately $12.2 billion . These undistributed foreign earnings were subject to the U.S. one-time mandatory transition tax and are eligible to be repatriated to the U.S. without additional U.S. tax under the Tax Act. The Company has reevaluated its historic indefinite reinvestment assertion as a result of the enactment of the Tax Act and determined that any historical or future undistributed earnings of foreign subsidiaries are no longer considered to be indefinitely reinvested . A portion of the Company’s foreign operations are benefiting from a tax holiday, which is set to expire in 2021 . This tax holiday may be extended when certain conditions are met or may be terminated early if certain conditions are not met. The tax benefit attributable to this tax holiday was $126 million , $187 million and $173 million for the fiscal years ended May 31, 2018 , 2017 and 2016 , respectively. The benefit of the tax holiday on diluted earnings per common share was $0.08 , $0.11 and $0.10 for the fiscal years ended May 31, 2018 , 2017 and 2016 , respectively. Deferred tax assets at May 31, 2018 and 2017 were reduced by a valuation allowance primarily relating to tax benefits of certain entities with operating losses. There was a $13 million net increase in the valuation allowance for the year ended May 31, 2018 , compared to a $30 million net increase for the year ended May 31, 2017 and $43 million net increase for the year ended May 31, 2016 . The Company no longer has recorded deferred tax assets for foreign tax credit carry-forwards; the $208 million recorded at May 31, 2017 was fully utilized to offset the impacts of transition tax. The Company has available domestic and foreign loss carry-forwards of $289 million at May 31, 2018 . Such losses will expire as follows: Year Ending May 31, (In millions) 2019 2020 2021 2022 2023-2039 Indefinite Total Net operating losses $ 1 $ 5 $ 2 $ 1 $ 91 $ 189 $ 289

Common Stock and Stock-Based Compensation	NOTE 11 — Common Stock and Stock-Based Compensation The authorized number of shares of Class A Common Stock, no par value, and Class B Common Stock, no par value, are 400 million and 2,400 million , respectively. Each share of Class A Common Stock is convertible into one share of Class B Common Stock. Voting rights of Class B Common Stock are limited in certain circumstances with respect to the election of directors. There are no differences in the dividend and liquidation preferences or participation rights of the holders of Class A and Class B Common Stock. From time to time, the Company’s Board of Directors authorizes share repurchase programs for the repurchase of Class B Common Stock. The value of repurchased shares is deducted from Total shareholders‘ equity through allocation to Capital in excess of stated value and Retained earnings . The NIKE, Inc. Stock Incentive Plan (the “Stock Incentive Plan”) provides for the issuance of up to 718 million previously unissued shares of Class B Common Stock in connection with equity awards granted under the Stock Incentive Plan. The Stock Incentive Plan authorizes the grant of non-statutory stock options, incentive stock options, stock appreciation rights, restricted stock, restricted stock units and performance-based awards. The exercise price for stock options and stock appreciation rights may not be less than the fair market value of the underlying shares on the date of grant. A committee of the Board of Directors administers the Stock Incentive Plan. The committee has the authority to determine the employees to whom awards will be made, the amount of the awards and the other terms and conditions of the awards. Substantially all stock option grants outstanding under the Stock Incentive Plan are granted in the first quarter of each fiscal year, vest ratably over four years and expire ten years from the date of grant. The following table summarizes the Company’s total stock-based compensation expense recognized in Cost of sales or Operating overhead expense , as applicable: Year Ended May 31, (In millions) 2018 2017 2016 Stock options (1) $ 149 $ 145 $ 171 ESPPs 34 36 31 Restricted stock 35 34 34 TOTAL STOCK-BASED COMPENSATION EXPENSE $ 218 $ 215 $ 236 (1) Expense for stock options includes the expense associated with stock appreciation rights.

Accelerated stock option expense was $18 million , $14 million and $30 million for the years ended May 31, 2018 , 2017 and 2016 , respectively. As of May 31, 2018 , the Company had $195 million of unrecognized compensation costs from stock options, net of estimated forfeitures, to be recognized in Cost of sales or Operating overhead expense , as applicable, over a weighted average remaining period of 2.0 years. The weighted average fair value per share of the options granted during the years ended May 31, 2018 , 2017 and 2016 , computed as of the grant date using the Black-Scholes pricing model, was $9.82 , $9.38 and $12.66 , respectively. The weighted average assumptions used to estimate these fair values are as follows: Year Ended May 31, 2018 2017 2016 Dividend yield 1.2 % 1.1 % 1.0 % Expected volatility 16.4 % 17.4 % 23.6 % Weighted average expected life (in years) 6.0 6.0 5.8 Risk-free interest rate 2.0 % 1.3 % 1.7 % The Company estimates the expected volatility based on the implied volatility in market traded options on the Company’s common stock with a term greater than one year, along with other factors. The weighted average expected life of options is based on an analysis of historical and expected future exercise patterns. The interest rate is based on the U.S. Treasury (constant maturity) risk-free rate in effect at the date of grant for periods corresponding with the expected term of the options. The following summarizes the stock option transactions under the plan discussed above: Shares (1) Weighted Average Option Price (In millions) Options outstanding May 31, 2015 116.2 $ 23.50 Exercised (22.5 ) 17.75 Forfeited (2.3 ) 39.96 Granted 20.6 56.41 Options outstanding May 31, 2016 112.0 30.38 Exercised (17.1 ) 20.42 Forfeited (2.3 ) 49.47 Granted 12.2 57.81 Options outstanding May 31, 2017 104.8 34.79 Exercised (24.1 ) 25.07 Forfeited (4.3 ) 55.31 Granted 16.8 59.08 Options outstanding May 31, 2018 93.2 $ 40.73 Options exercisable at May 31, 2016 66.5 $ 21.48 2017 67.9 26.03 2018 58.5 31.60 (1) Includes stock appreciation rights transactions. The weighted average contractual life remaining for options outstanding and options exercisable at May 31, 2018 was 5.7 years and 4.4 years, respectively. The aggregate intrinsic value for options outstanding and exercisable at May 31, 2018 was $2,896 million and $2,352 million , respectively. The aggregate intrinsic value was the amount by which the market value of the underlying stock exceeded the exercise price of the options. The total intrinsic value of the options exercised during the years ended May 31, 2018 , 2017 and 2016 was $889 million , $594 million and $946 million , respectively. In addition to the Stock Incentive Plan, the Company gives employees the right to purchase shares at a discount to the market price under employee stock purchase plans (ESPPs). Subject to the annual statutory limit, employees are eligible to participate through payroll deductions of up to 10% of their compensation. At the end of each six -month offering period, shares are purchased by the participants at 85% of the lower of the fair market value at the beginning or the end of the offering period. Employees purchased 3.1 million , 3.1 million and 2.5 million shares during each of the three years ended May 31, 2018 , 2017 and 2016 , respectively. From time to time, the Company grants restricted stock and restricted stock units to key employees under the Stock Incentive Plan. The number of shares underlying such awards granted to employees during the years ended May 31, 2018 , 2017 and 2016 were 1.8 million , 0.4 million and 1.0 million , respectively, with weighted average values per share of $62.51 , $57.59 and $54.87 , respectively. Recipients of restricted stock are entitled to cash dividends and to vote their respective shares throughout the period of restriction. Recipients of restricted stock units are entitled to dividend equivalent cash payments upon vesting. The value of all grants of restricted stock and restricted stock units was established by the market price on the date of grant. During the years ended May 31, 2018 , 2017 and 2016 , the aggregate fair value of restricted stock and restricted stock units vested was $113 million , $60 million and $49 million , respectively, determined as of the date of vesting. As of May 31, 2018 , the Company had $104 million of unrecognized compensation costs from restricted stock and restricted stock units to be recognized in Operating overhead expense over a weighted average period of 2.4 years.

In connection with various contracts and agreements, the Company provides routine indemnification relating to the enforceability of intellectual property rights, coverage for legal issues that arise and other items where the Company is acting as the guarantor. Currently, the Company has several such agreements in place. However, based on the Company’s historical experience and the estimated probability of future loss, the Company has determined the fair value of such indemnification is not material to the Company’s financial position or results of operations. In the ordinary course of its business, the Company is involved in various legal proceedings involving contractual and employment relationships, product liability claims, trademark rights and a variety of other matters. While the Company cannot predict the outcome of its pending legal matters with certainty, the Company does not believe any currently identified claim, proceeding or litigation, either individually or in aggregate, will have a material impact on the Company’s results of operations, financial position or cash flows.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Risk Management and Derivatives	NOTE 16 — Risk Management and Derivatives The Company is exposed to global market risks, including the effect of changes in foreign currency exchange rates and interest rates, and uses derivatives to manage financial exposures that occur in the normal course of business. The Company does not hold or issue derivatives for trading or speculative purposes. The Company may elect to designate certain derivatives as hedging instruments under the accounting standards for derivatives and hedging. The Company formally documents all relationships between designated hedging instruments and hedged items as well as its risk management objectives and strategies for undertaking hedge transactions. This process includes linking all derivatives designated as hedges to either recognized assets or liabilities or forecasted transactions. The majority of derivatives outstanding as of May 31, 2018 are designated as foreign currency cash flow hedges, primarily for Euro/U.S. Dollar, British Pound/Euro and Japanese Yen/U.S. Dollar currency pairs . All derivatives are recognized on the Consolidated Balance Sheets at fair value and classified based on the instrument’s maturity date. The following table presents the fair values of derivative instruments included within the Consolidated Balance Sheets as of May 31, 2018 and 2017 : Derivative Assets Derivative Liabilities (In millions) Balance Sheet Location 2018 2017 Balance Sheet Location 2018 2017 Derivatives formally designated as hedging instruments: Foreign exchange forwards and options Prepaid expenses and other current assets $ 118 $ 113 Accrued liabilities $ 156 $ 59 Foreign exchange forwards and options Deferred income taxes and other assets 152 13 Deferred income taxes and other liabilities — 73 Total derivatives formally designated as hedging instruments 270 126 156 132 Derivatives not designated as hedging instruments: Foreign exchange forwards and options Prepaid expenses and other current assets 119 103 Accrued liabilities 26 107 Embedded derivatives Prepaid expenses and other current assets 3 1 Accrued liabilities 2 2 Foreign exchange forwards and options Deferred income taxes and other assets — 2 Deferred income taxes and other liabilities — 7 Embedded derivatives Deferred income taxes and other assets 8 9 Deferred income taxes and other liabilities 6 6 Total derivatives not designated as hedging instruments 130 115 34 122 TOTAL DERIVATIVES $ 400 $ 241 $ 190 $ 254 The following tables present the amounts affecting the Consolidated Statements of Income for the years ended May 31, 2018 , 2017 and 2016 : (In millions) Amount of Gain (Loss) Recognized in Other Comprehensive Income on Derivatives (1) Amount of Gain (Loss) Reclassified from Accumulated Other Comprehensive Income into Income (1) Year Ended May 31, Location of Gain (Loss) Reclassified From Accumulated Other Comprehensive Income into Income Year Ended May 31, 2018 2017 2016 2018 2017 2016 Derivatives designated as cash flow hedges: Foreign exchange forwards and options $ 19 $ 72 $ 90 Revenues $ 34 $ 96 $ (88 ) Foreign exchange forwards and options (50 ) 43 (57 ) Cost of sales (90 ) 339 586 Foreign exchange forwards and options 1 (4 ) — Total selling and administrative expense 1 — — Foreign exchange forwards and options (19 ) 37 (25 ) Other expense (income), net (69 ) 199 219 Interest rate swaps (2) — (54 ) (83 ) Interest expense (income), net (7 ) (4 ) — Total designated cash flow hedges $ (49 ) $ 94 $ (75 ) $ (131 ) $ 630 $ 717 (1) For the years ended May 31, 2018 , 2017 and 2016 , the amounts recorded in Other expense (income), net as a result of hedge ineffectiveness and the discontinuance of cash flow hedges because the forecasted transactions were no longer probable of occurring were immaterial.

Cash Flow Hedges All changes in fair value of derivatives designated as cash flow hedges, excluding any ineffective portion, are recorded in Accumulated other comprehensive income until Net income is affected by the variability of cash flows of the hedged transaction. Effective hedge results are classified within the Consolidated Statements of Income in the same manner as the underlying exposure. The ineffective portion of the unrealized gains and losses on these contracts, if any, is recorded immediately in earnings. Derivative instruments designated as cash flow hedges must be discontinued when it is no longer probable the forecasted hedged transaction will occur in the initially identified time period. The gains and losses associated with discontinued derivative instruments in Accumulated other comprehensive income will be recognized immediately in Other expense (income), net , if it is probable the forecasted hedged transaction will not occur by the end of the initially identified time period or within an additional two -month period thereafter. In all situations in which hedge accounting is discontinued and the derivative remains outstanding, the Company will account for the derivative as an undesignated instrument as discussed below. The purpose of the Company ’ s foreign exchange risk management program is to lessen both the positive and negative effects of currency fluctuations on the Company ’ s consolidated results of operations, financial position and cash flows. Foreign currency exposures the Company may elect to hedge in this manner include product cost exposures, non-functional currency denominated external and intercompany revenues, selling and administrative expenses, investments in U.S. Dollar-denominated available-for-sale debt securities and certain other intercompany transactions. Product cost exposures are primarily generated through non-functional currency denominated product purchases and the foreign currency adjustment program described below. NIKE entities primarily purchase products in two ways: (1) Certain NIKE entities purchase product from the NIKE Trading Company (NTC), a wholly owned sourcing hub that buys NIKE branded products from third party factories, predominantly in U.S. Dollars. The NTC, whose functional currency is the U.S. Dollar, then sells the product to NIKE entities in their respective functional currencies. NTC sales to a NIKE entity with a different functional currency results in a foreign currency exposure for the NTC. (2) Other NIKE entities purchase product directly from third party factories in U.S. Dollars. These purchases generate a foreign currency exposure for those NIKE entities with a functional currency other than the U.S. Dollar. The Company operates a foreign currency adjustment program with certain factories. The program is designed to more effectively manage foreign currency risk by assuming certain of the factories’ foreign currency exposures, some of which are natural offsets to the Company ’ s existing foreign currency exposures. Under this program, the Company’s payments to these factories are adjusted for rate fluctuations in the basket of currencies (“factory currency exposure index”) in which the labor, materials and overhead costs incurred by the factories in the production of NIKE branded products (“factory input costs”) are denominated. For the portion of the indices denominated in the local or functional currency of the factory, the Company may elect to place formally designated cash flow hedges. For all currencies within the indices, excluding the U.S. Dollar and the local or functional currency of the factory, an embedded derivative contract is created upon the factory’s acceptance of NIKE’s purchase order. Embedded derivative contracts are separated from the related purchase order, as further described within the Embedded Derivatives section below. The Company’s policy permits the utilization of derivatives to reduce its foreign currency exposures where internal netting or other strategies cannot be effectively employed. Typically, the Company may enter into hedge contracts starting up to 12 to 24 months in advance of the forecasted transaction and may place incremental hedges up to 100% of the exposure by the time the forecasted transaction occurs. The total notional amount of outstanding foreign currency derivatives designated as cash flow hedges was $12.2 billion as of May 31, 2018 . As of May 31, 2018 , $96 million of deferred net gains (net of tax) on both outstanding and matured derivatives in Accumulated other comprehensive income are expected to be reclassified to Net income during the next 12 months concurrent with the underlying hedged transactions also being recorded in Net income . Actual amounts ultimately reclassified to Net income are dependent on the exchange rates in effect when derivative contracts currently outstanding mature. As of May 31, 2018 , the maximum term over which the Company is hedging exposures to the variability of cash flows for its forecasted transactions was 24 months. Fair Value Hedges The Company has, in the past, been exposed to the risk of changes in the fair value of certain fixed-rate debt attributable to changes in interest rates. Derivatives used by the Company to hedge this risk are receive-fixed, pay-variable interest rate swaps. All interest rate swaps designated as fair value hedges of the related long-term debt meet the shortcut method requirements under U.S. GAAP. Accordingly, changes in the fair values of the interest rate swaps are considered to exactly offset changes in the fair value of the underlying long-term debt. The Company recorded no ineffectiveness from its interest rate swaps designated as fair value hedges for the years ended May 31, 2018 , 2017 or 2016 . The Company had no interest rate swaps designated as fair value hedges as of May 31, 2018. Net Investment Hedges The Company has, in the past, hedged and may, in the future, hedge the risk of variability in foreign currency-denominated net investments in wholly-owned international operations. All changes in fair value of the derivatives designated as net investment hedges, except ineffective portions, are reported in Accumulated other comprehensive income along with the foreign currency translation adjustments on those investments. The ineffective portion of the unrealized gains and losses on these contracts, if any, are recorded immediately in earnings. The Company recorded no ineffectiveness from net investment hedges for the years ended May 31, 2018 , 2017 or 2016 . The Company had no outstanding net investment hedges as of May 31, 2018 . Undesignated Derivative Instruments The Company may elect to enter into foreign exchange forwards to mitigate the change in fair value of specific assets and liabilities on the Consolidated Balance Sheets and/or the embedded derivative contracts. These undesignated instruments are recorded at fair value as a derivative asset or liability on the Consolidated Balance Sheets with their corresponding change in fair value recognized in Other expense (income), net , together with the re-measurement gain or loss from the hedged balance sheet position and/or embedded derivative contract. The total notional amount of outstanding undesignated derivative instruments was $6.1 billion as of May 31, 2018 . Embedded Derivatives As part of the foreign currency adjustment program described above, an embedded derivative contract is created upon the factory’s acceptance of NIKE’s purchase order for currencies within the factory currency exposure indices that are neither the U.S. Dollar nor the local or functional currency of the factory. In addition, embedded derivative contracts are created when the Company enters into certain other contractual agreements which have payments that are indexed to currencies that are not the functional currency of either substantial party to the contracts. Embedded derivative contracts are treated as foreign currency forward contracts that are bifurcated from the related purchase order and recorded at fair value as a derivative asset or liability on the Consolidated Balance Sheets with their corresponding change in fair value recognized in Other expense (income), net , through the date the foreign currency fluctuations cease to exist. At May 31, 2018 , the total notional amount of all embedded derivatives outstanding was approximately $260 million . Credit Risk The Company is exposed to credit-related losses in the event of nonperformance by counterparties to hedging instruments. The counterparties to all derivative transactions are major financial institutions with investment grade credit ratings; however, this does not eliminate the Company’s exposure to credit risk with these institutions. This credit risk is limited to the unrealized gains in such contracts should any of these counterparties fail to perform as contracted. To manage this risk, the Company has established strict counterparty credit guidelines that are continually monitored. The Company’s derivative contracts contain credit risk-related contingent features designed to protect against significant deterioration in counterparties’ creditworthiness and their ultimate ability to settle outstanding derivative contracts in the normal course of business. The Company’s bilateral credit-related contingent features generally require the owing entity, either the Company or the derivative counterparty, to post collateral for the portion of the fair value in excess of $50 million should the fair value of outstanding derivatives per counterparty be greater than $50 million . Additionally, a certain level of decline in credit rating of either the Company or the counterparty could also trigger collateral requirements. As of May 31, 2018 , the Company was in compliance with all credit risk-related contingent features and had no derivative instruments with credit risk-related contingent features in a net liability position. Accordingly, the Company was not required to post any collateral as a result of these contingent features. Further, as of May 31, 2018 , the Company had received $23 million of cash collateral from various counterparties to its derivative contracts (refer to Note 6 — Fair Value Measurements ). The Company considers the impact of the risk of counterparty default to be immaterial .

Segment Reporting [Abstract]
Operating Segments and Related Information	NOTE 17 — Operating Segments and Related Information The Company’s operating segments are evidence of the structure of the Company’s internal organization. The NIKE Brand segments are defined by geographic regions for operations participating in NIKE Brand sales activity. Each NIKE Brand geographic segment operates predominantly in one industry: the design, development, marketing and selling of athletic footwear, apparel and equipment. In June 2017, NIKE, Inc. announced a new company alignment designed to allow NIKE to better serve the consumer personally, at scale. As a result of this organizational realignment, the Company’s reportable operating segments for the NIKE Brand are: North America; Europe, Middle East & Africa; Greater China; and Asia Pacific & Latin America, and include results for the NIKE, Jordan and Hurley brands. Certain prior year amounts have been reclassified to conform to fiscal 2018 presentation. This includes reclassified operating segment data to reflect the changes in the Company’s operating structure, which became effective June 1, 2017. These changes had no impact on previously reported consolidated statements of income, balance sheets, statements of cash flows or statements of shareholders’ equity. The Company’s NIKE Direct operations are managed within each NIKE Brand geographic operating segment. Converse is also a reportable segment for the Company, and operates in one industry: the design, marketing, licensing and selling of casual sneakers, apparel and accessories. Global Brand Divisions is included within the NIKE Brand for presentation purposes to align with the way management views the Company. Global Brand Divisions primarily represents NIKE Brand licensing businesses that are not part of a geographic operating segment, and demand creation, operating overhead and product creation and design expenses that are centrally managed for the NIKE Brand. Corporate consists largely of unallocated general and administrative expenses, including expenses associated with centrally managed departments; depreciation and amortization related to the Company’s headquarters; unallocated insurance, benefit and compensation programs, including stock-based compensation; and certain foreign currency gains and losses, including certain hedge gains and losses. The primary financial measure used by the Company to evaluate performance of individual operating segments is earnings before interest and taxes (commonly referred to as “EBIT”), which represents Net income before Interest expense (income), net and Income tax expense in the Consolidated Statements of Income. As part of the Company’s centrally managed foreign exchange risk management program, standard foreign currency rates are assigned twice per year to each NIKE Brand entity in the Company’s geographic operating segments and to Converse. These rates are set approximately nine and twelve months in advance of the future selling seasons to which they relate (specifically, for each currency, one standard rate applies to the fall and holiday selling seasons and one standard rate applies to the spring and summer selling seasons) based on average market spot rates in the calendar month preceding the date they are established. Inventories and Cost of sales for geographic operating segments and Converse reflect the use of these standard rates to record non-functional currency product purchases in the entity’s functional currency. Differences between assigned standard foreign currency rates and actual market rates are included in Corporate, together with foreign currency hedge gains and losses generated from the Company’s centrally managed foreign exchange risk management program and other conversion gains and losses. Accounts receivable, net , Inventories and Property, plant and equipment, net for operating segments are regularly reviewed by management and, therefore, are provided below.

Summary of Significant Accoun27

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	May 31, 2018
Accounting Policies [Abstract]
Basis of Consolidation	Basis of Consolidation The Consolidated Financial Statements include the accounts of NIKE, Inc. and its subsidiaries (the “Company”). All significant intercompany transactions and balances have been eliminated. On November 19, 2015, the Company announced a two -for-one split of both NIKE Class A and Class B Common Stock. The stock split was in the form of a 100 percent stock dividend payable on December 23, 2015 to shareholders of record at the close of business on December 9, 2015. Common stock began trading at the split-adjusted price on December 24, 2015. All share and per share amounts presented reflect the stock split.
Reclassifications	Reclassifications Certain prior year amounts have been reclassified to conform to fiscal 2018 presentation, including reclassified geographic operating segment data to reflect the changes in the Company’s operating structure, which became effective on June 1, 2017. Refer to Note 17 — Operating Segments and Related Information for additional information.
Revenue Recognition	Revenue Recognition Wholesale revenues are recognized when title and the risks and rewards of ownership have passed to the customer, based on the terms of sale. This occurs upon shipment or upon receipt by the customer depending on the country of the sale and the agreement with the customer. Retail store revenues are recorded at the time of sale and digital commerce revenues are recorded upon delivery to the customer. Amounts collected from customers for sales or value added tax are recorded on a net basis. Provisions for post-invoice sales discounts, returns and miscellaneous claims from customers are estimated and recorded as a reduction to revenue at the time of sale. Post-invoice sales discounts consist of contractual programs with certain customers or discretionary discounts expected to be granted to certain customers at a later date. Estimates of discretionary discounts, returns and claims are based on (1) historical rates, (2) specific identification of outstanding claims and outstanding returns not yet received from customers and (3) estimated discounts, returns and claims expected, but not yet finalized with customers.
Cost of Sales	Cost of Sales Cost of sales consists primarily of inventory costs, as well as warehousing costs (including the cost of warehouse labor), third-party royalties, certain foreign currency hedge gains and losses and product design costs. Outbound shipping and handling costs are expensed as incurred and included in Cost of sales .
Demand Creation Expense	Demand Creation Expense Demand creation expense consists of advertising and promotion costs, including costs of endorsement contracts, complimentary product, television, digital and print advertising and media costs, brand events and retail brand presentation. Advertising production costs are expensed the first time an advertisement is run. Advertising media costs are expensed when the advertisement appears. Costs related to brand events are expensed when the event occurs. Costs related to retail brand presentation are expensed when the presentation is complete and delivered. A significant amount of the Company’s promotional expenses result from payments under endorsement contracts. In general, endorsement payments are expensed on a straight-line basis over the term of the contract. However, certain contract elements may be accounted for differently based upon the facts and circumstances of each individual contract. Prepayments made under contracts are included in Prepaid expenses and other current assets or Deferred income taxes and other assets depending on the period to which the prepayment applies. Certain contracts provide for contingent payments to endorsers based upon specific achievements in their sports (e.g., winning a championship). The Company records Demand creation expense for these amounts when the endorser achieves the specific goal. Certain contracts provide for variable payments based upon endorsers maintaining a level of performance in their sport over an extended period of time (e.g., maintaining a specified ranking in a sport for a year). When the Company determines payments are probable, the amounts are reported in Demand creation expense ratably over the contract period based on the Company’s best estimate of the endorser’s performance. In these instances, to the extent actual payments to the endorser differ from the Company’s estimate due to changes in the endorser’s performance, adjustments to Demand creation expense may be recorded in a future period. Certain contracts provide for royalty payments to endorsers based upon a predetermined percent of sales of particular products. The Company expenses these payments in Cost of sales as the related sales occur. In certain contracts, the Company offers minimum guaranteed royalty payments. For contracts the Company estimates will not meet the minimum guaranteed amount of royalty fees through sales of product, the Company records the amount of the guaranteed payment in excess of that earned through sales of product in Demand creation expense uniformly over the contract period. Through cooperative advertising programs, the Company reimburses customers for certain costs of advertising the Company’s products. The Company records these costs in Demand creation expense at the point in time when it is obligated to its customers for the costs. This obligation may arise prior to the related advertisement being run.
Operating Overhead Expense	Operating Overhead Expense Operating overhead expense consists primarily of wage and benefit-related expenses, research and development costs, as well as other administrative expenses, such as rent, depreciation and amortization, professional services, meetings and travel.
Cash and Equivalents	Cash and Equivalents Cash and equivalents represent cash and short-term, highly liquid investments, that are both readily convertible to known amounts of cash, and so near their maturity they present insignificant risk of changes in value because of changes in interest rates, including commercial paper, U.S. Treasury, U.S. Agency, money market funds, time deposits and corporate debt securities with maturities of 90 days or less at the date of purchase.
Short-Term Investments	Short-Term Investments Short-term investments consist of highly liquid investments, including commercial paper, U.S. Treasury, U.S. Agency, time deposits and corporate debt securities, with maturities over 90 days at the date of purchase. Debt securities the Company has the ability and positive intent to hold to maturity are carried at amortized cost. At May 31, 2018 and 2017 , the Company did not hold any short-term investments classified as trading or held-to-maturity. At May 31, 2018 and 2017 , Short-term investments consisted of available-for-sale securities. Available-for-sale securities are recorded at fair value with unrealized gains and losses reported, net of tax, in Accumulated other comprehensive income , unless unrealized losses are determined to be other than temporary. Realized gains and losses on the sale of securities are determined by specific identification. The Company considers all available-for-sale securities, including those with maturity dates beyond 12 months, as available to support current operational liquidity needs and, therefore, classifies all securities with maturity dates beyond 90 days at the date of purchase as current assets within Short-term investments on the Consolidated Balance Sheets.
Allowance for Uncollectible Accounts Receivable	Allowance for Uncollectible Accounts Receivable Accounts receivable, net consist primarily of amounts receivable from customers. The Company makes ongoing estimates relating to the collectability of its accounts receivable and maintains an allowance for estimated losses resulting from the inability of its customers to make required payments. In determining the amount of the allowance, the Company considers historical levels of credit losses and makes judgments about the creditworthiness of significant customers based on ongoing credit evaluations. Accounts receivable with anticipated collection dates greater than 12 months from the balance sheet date and related allowances are considered non-current and recorded in Deferred income taxes and other assets .
Inventory Valuation	Inventory Valuation Inventories are stated at lower of cost and net realizable value, and valued on either an average or a specific identification cost basis. In some instances, we ship product directly from our supplier to the customer, with the related inventory and cost of sales recognized on a specific identification basis. Inventory costs primarily consist of product cost from the Company’s suppliers, as well as inbound freight, import duties, taxes, insurance and logistics and other handling fees.
Property, Plant and Equipment and Depreciation	Property, Plant and Equipment and Depreciation Property, plant and equipment are recorded at cost. Depreciation is determined on a straight-line basis for land improvements, buildings and leasehold improvements over 2 to 40 years and for machinery and equipment over 2 to 15 years. Depreciation and amortization of assets used in manufacturing, warehousing and product distribution are recorded in Cost of sales . Depreciation and amortization of all other assets are recorded in Operating overhead expense .
Software Development Costs	Software Development Costs Internal Use Software : Expenditures for major software purchases and software developed for internal use are capitalized and amortized over a 2 to 12 -year period on a straight-line basis. The Company’s policy provides for the capitalization of external direct costs of materials and services associated with developing or obtaining internal use computer software. In addition, the Company also capitalizes certain payroll and payroll-related costs for employees who are directly associated with internal use computer software projects. The amount of capitalizable payroll costs with respect to these employees is limited to the time directly spent on such projects. Costs associated with preliminary project stage activities, training, maintenance and all other post-implementation stage activities are expensed as incurred.
Computer Software to be Sold, Leased or Otherwise Marketed	Computer Software to be Sold, Leased or Otherwise Marketed : Development costs of computer software to be sold, leased or otherwise marketed as an integral part of a product are subject to capitalization beginning when a product’s technological feasibility has been established and ending when a product is available for general release to customers. In most instances, the Company’s products are released soon after technological feasibility has been established. Therefore, software development costs incurred subsequent to achievement of technological feasibility are usually not significant, and generally most software development costs have been expensed as incurred.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets The Company reviews the carrying value of long-lived assets or asset groups to be used in operations whenever events or changes in circumstances indicate the carrying amount of the assets might not be recoverable. Factors that would necessitate an impairment assessment include a significant adverse change in the extent or manner in which an asset is used, a significant adverse change in legal factors or the business climate that could affect the value of the asset or a significant decline in the observable market value of an asset, among others. If such facts indicate a potential impairment, the Company would assess the recoverability of an asset group by determining if the carrying value of the asset group exceeds the sum of the projected undiscounted cash flows expected to result from the use and eventual disposition of the assets over the remaining economic life of the primary asset in the asset group. If the recoverability test indicates that the carrying value of the asset group is not recoverable, the Company will estimate the fair value of the asset group using appropriate valuation methodologies, which would typically include an estimate of discounted cash flows. Any impairment would be measured as the difference between the asset group’s carrying amount and its estimated fair value.
Goodwill and Indefinite-Lived Intangible Assets	Goodwill and Indefinite-Lived Intangible Assets The Company performs annual impairment tests on goodwill and intangible assets with indefinite lives in the fourth quarter of each fiscal year or when events occur or circumstances change that would, more likely than not, reduce the fair value of a reporting unit or an intangible asset with an indefinite life below its carrying value. Events or changes in circumstances that may trigger interim impairment reviews include significant changes in business climate, operating results, planned investments in the reporting unit, planned divestitures or an expectation the carrying amount may not be recoverable, among other factors. The Company may first assess qualitative factors to determine whether it is more likely than not the fair value of a reporting unit is less than its carrying amount. If, after assessing the totality of events and circumstances, the Company determines it is more likely than not the fair value of the reporting unit is greater than its carrying amount, the two-step impairment test is unnecessary. The two-step impairment test first requires the Company to estimate the fair value of its reporting units. If the carrying value of a reporting unit exceeds its fair value, the goodwill of that reporting unit is potentially impaired and the Company proceeds to step two of the impairment analysis. In step two of the analysis, the Company measures and records an impairment loss equal to the excess of the carrying value of the reporting unit’s goodwill over its implied fair value, if any. Indefinite-lived intangible assets primarily consist of acquired trade names and trademarks. The Company may first perform a qualitative assessment to determine whether it is more likely than not an indefinite-lived intangible asset is impaired. If, after assessing the totality of events and circumstances, the C ompany determines it is more likely than not that the indefinite-lived intangible asset is not impaired, no quantitative fair value measurement is necessary. If a quantitative fair value measurement calculation is required for these intangible assets, the Company utilizes the relief-from-royalty method. This method assumes trade names and trademarks have value to the extent their owner is relieved of the obligation to pay royalties for the benefits received from them. This method requires the Company to estimate the future revenue for the related brands, the appropriate royalty rate and the weighted average cost of capital.
Operating Leases	Operating Leases The Company leases retail store space, certain distribution and warehouse facilities, office space, equipment and other non-real estate assets under operating leases. Operating lease agreements may contain rent escalation clauses, renewal options, rent holidays or certain landlord incentives, including tenant improvement allowances. Rent expense for non-cancelable operating leases with scheduled rent increases or landlord incentives are recognized on a straight-line basis over the lease term, beginning with the effective lease commencement date, which is generally the date in which the Company takes possession of or controls the physical use of the property. Certain leases also provide for contingent rent, which is generally determined as a percent of sales in excess of specified levels. A contingent rent liability is recognized together with the corresponding rent expense when specified levels have been achieved or when the Company determines that achieving the specified levels during the period is probable.
Fair Value Measurements	Fair Value Measurements The Company measures certain financial assets and liabilities at fair value on a recurring basis, including derivatives and available-for-sale securities. Fair value is the price the Company would receive to sell an asset or pay to transfer a liability in an orderly transaction with a market participant at the measurement date. The Company uses a three-level hierarchy established by the Financial Accounting Standards Board (FASB) that prioritizes fair value measurements based on the types of inputs used for the various valuation techniques (market approach, income approach and cost approach). The levels of the fair value hierarchy are described below: • Level 1: Quoted prices in active markets for identical assets or liabilities. • Level 2: Inputs other than observable quoted prices for the asset or liability, either directly or indirectly; these include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active. • Level 3: Unobservable inputs with little or no market data available, which require the reporting entity to develop its own assumptions. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability. Financial assets and liabilities are classified in their entirety based on the most conservative level of input that is significant to the fair value measurement. Pricing vendors are utilized for a majority of Level 1 and Level 2 investments. These vendors either provide a quoted market price in an active market or use observable inputs without applying significant adjustments in their pricing. Observable inputs include broker quotes, interest rates and yield curves observable at commonly quoted intervals, volatilities and credit risks. The fair value of derivative contracts is determined using observable market inputs such as the daily market foreign currency rates, forward pricing curves, currency volatilities, currency correlations and interest rates and considers nonperformance risk of the Company and its counterparties. Level 1 investments include U.S. Treasury securities. Assets and liabilities included within Level 2 include commercial paper, U.S. Agency securities, money market funds, time deposits, corporate debt securities and derivative contracts. Level 3 investments are valued using internally developed models with unobservable inputs and are an immaterial portion of our portfolio. The Company’s fair value measurement process includes comparing fair values to another independent pricing vendor to ensure appropriate fair values are recorded.
Foreign Currency Translation and Foreign Currency Transactions	Foreign Currency Translation and Foreign Currency Transactions Adjustments resulting from translating foreign functional currency financial statements into U.S. Dollars are included in the foreign currency translation adjustment, a component of Accumulated other comprehensive income in Total shareholders’ equity . The Company’s global subsidiaries have various assets and liabilities, primarily receivables and payables, which are denominated in currencies other than their functional currency. These balance sheet items are subject to re-measurement, the impact of which is recorded in Other expense (income), net , within the Consolidated Statements of Income.
Accounting for Derivatives and Hedging Activities	Accounting for Derivatives and Hedging Activities The Company uses derivative financial instruments to reduce its exposure to changes in foreign currency exchange rates and interest rates. All derivatives are recorded at fair value on the Consolidated Balance Sheets and changes in the fair value of derivative financial instruments are either recognized in Accumulated other comprehensive income (a component of Total shareholders’ equity ), Long-term debt or Net income depending on the nature of the underlying exposure, whether the derivative is formally designated as a hedge and, if designated, the extent to which the hedge is effective. The Company classifies the cash flows at settlement from derivatives in the same category as the cash flows from the related hedged items. For undesignated hedges and designated cash flow hedges, this is primarily within the Cash provided by operations component of the Consolidated Statements of Cash Flows. For designated net investment hedges, this is within the Cash used by investing activities component of the Consolidated Statements of Cash Flows. For the Company’s fair value hedges, which are interest rate swaps used to mitigate the change in fair value of its fixed-rate debt attributable to changes in interest rates, the related cash flows from periodic interest payments are reflected within the Cash provided by operations component of the Consolidated Statements of Cash Flows.
Hedging Derivatives	The Company elects to record the gross assets and liabilities of its derivative financial instruments on the Consolidated Balance Sheets. The Company’s derivative financial instruments are subject to master netting arrangements that allow for the offset of assets and liabilities in the event of default or early termination of the contract. Any amounts of cash collateral received related to these instruments associated with the Company ’ s credit-related contingent features are recorded in Cash and equivalents and Accrued liabilities , the latter of which would further offset against the Company’s derivative asset balance (refer to Note 16 — Risk Management and Derivatives ). Any amounts of cash collateral posted related to these instruments associated with the Company ’ s credit-related contingent features are recorded in Prepaid expenses and other current assets , which would further offset against the Company ’ s derivative liability balance (refer to Note 16 — Risk Management and Derivatives ). Cash collateral received or posted related to the Company ’ s credit related contingent features is presented in the Cash provided by operations component of the Consolidated Statements of Cash Flows. Any amounts of non-cash collateral received, such as securities, are not recorded on the Consolidated Balance Sheets pursuant to U.S. GAAP. Cash Flow Hedges All changes in fair value of derivatives designated as cash flow hedges, excluding any ineffective portion, are recorded in Accumulated other comprehensive income until Net income is affected by the variability of cash flows of the hedged transaction. Effective hedge results are classified within the Consolidated Statements of Income in the same manner as the underlying exposure. The ineffective portion of the unrealized gains and losses on these contracts, if any, is recorded immediately in earnings. Derivative instruments designated as cash flow hedges must be discontinued when it is no longer probable the forecasted hedged transaction will occur in the initially identified time period. The gains and losses associated with discontinued derivative instruments in Accumulated other comprehensive income will be recognized immediately in Other expense (income), net , if it is probable the forecasted hedged transaction will not occur by the end of the initially identified time period or within an additional two -month period thereafter. In all situations in which hedge accounting is discontinued and the derivative remains outstanding, the Company will account for the derivative as an undesignated instrument as discussed below. The purpose of the Company ’ s foreign exchange risk management program is to lessen both the positive and negative effects of currency fluctuations on the Company ’ s consolidated results of operations, financial position and cash flows. Foreign currency exposures the Company may elect to hedge in this manner include product cost exposures, non-functional currency denominated external and intercompany revenues, selling and administrative expenses, investments in U.S. Dollar-denominated available-for-sale debt securities and certain other intercompany transactions. Product cost exposures are primarily generated through non-functional currency denominated product purchases and the foreign currency adjustment program described below. NIKE entities primarily purchase products in two ways: (1) Certain NIKE entities purchase product from the NIKE Trading Company (NTC), a wholly owned sourcing hub that buys NIKE branded products from third party factories, predominantly in U.S. Dollars. The NTC, whose functional currency is the U.S. Dollar, then sells the product to NIKE entities in their respective functional currencies. NTC sales to a NIKE entity with a different functional currency results in a foreign currency exposure for the NTC. (2) Other NIKE entities purchase product directly from third party factories in U.S. Dollars. These purchases generate a foreign currency exposure for those NIKE entities with a functional currency other than the U.S. Dollar. The Company operates a foreign currency adjustment program with certain factories. The program is designed to more effectively manage foreign currency risk by assuming certain of the factories’ foreign currency exposures, some of which are natural offsets to the Company ’ s existing foreign currency exposures. Under this program, the Company’s payments to these factories are adjusted for rate fluctuations in the basket of currencies (“factory currency exposure index”) in which the labor, materials and overhead costs incurred by the factories in the production of NIKE branded products (“factory input costs”) are denominated. For the portion of the indices denominated in the local or functional currency of the factory, the Company may elect to place formally designated cash flow hedges. For all currencies within the indices, excluding the U.S. Dollar and the local or functional currency of the factory, an embedded derivative contract is created upon the factory’s acceptance of NIKE’s purchase order. Embedded derivative contracts are separated from the related purchase order, as further described within the Embedded Derivatives section below. The Company’s policy permits the utilization of derivatives to reduce its foreign currency exposures where internal netting or other strategies cannot be effectively employed. Typically, the Company may enter into hedge contracts starting up to 12 to 24 months in advance of the forecasted transaction and may place incremental hedges up to 100% of the exposure by the time the forecasted transaction occurs. Net Investment Hedges The Company has, in the past, hedged and may, in the future, hedge the risk of variability in foreign currency-denominated net investments in wholly-owned international operations. All changes in fair value of the derivatives designated as net investment hedges, except ineffective portions, are reported in Accumulated other comprehensive income along with the foreign currency translation adjustments on those investments. The ineffective portion of the unrealized gains and losses on these contracts, if any, are recorded immediately in earnings. Fair Value Hedges The Company has, in the past, been exposed to the risk of changes in the fair value of certain fixed-rate debt attributable to changes in interest rates. Derivatives used by the Company to hedge this risk are receive-fixed, pay-variable interest rate swaps. All interest rate swaps designated as fair value hedges of the related long-term debt meet the shortcut method requirements under U.S. GAAP. Accordingly, changes in the fair values of the interest rate swaps are considered to exactly offset changes in the fair value of the underlying long-term debt.
Undesignated Derivative Instruments	Undesignated Derivative Instruments The Company may elect to enter into foreign exchange forwards to mitigate the change in fair value of specific assets and liabilities on the Consolidated Balance Sheets and/or the embedded derivative contracts. These undesignated instruments are recorded at fair value as a derivative asset or liability on the Consolidated Balance Sheets with their corresponding change in fair value recognized in Other expense (income), net , together with the re-measurement gain or loss from the hedged balance sheet position and/or embedded derivative contract.
Embedded Derivatives	Embedded Derivatives As part of the foreign currency adjustment program described above, an embedded derivative contract is created upon the factory’s acceptance of NIKE’s purchase order for currencies within the factory currency exposure indices that are neither the U.S. Dollar nor the local or functional currency of the factory. In addition, embedded derivative contracts are created when the Company enters into certain other contractual agreements which have payments that are indexed to currencies that are not the functional currency of either substantial party to the contracts. Embedded derivative contracts are treated as foreign currency forward contracts that are bifurcated from the related purchase order and recorded at fair value as a derivative asset or liability on the Consolidated Balance Sheets with their corresponding change in fair value recognized in Other expense (income), net , through the date the foreign currency fluctuations cease to exist.
Stock-Based Compensation	Stock-Based Compensation The Company accounts for stock-based compensation by estimating the fair value of options and stock appreciation rights granted under the NIKE, Inc. Stock Incentive Plan and employees’ purchase rights under the employee stock purchase plans (ESPPs) using the Black-Scholes option pricing model. The Company recognizes this fair value as Cost of sales or Operating overhead expense , as applicable, in the Consolidated Statements of Income over the vesting period using the straight-line method. From time to time, the Company’s Board of Directors authorizes share repurchase programs for the repurchase of Class B Common Stock. The value of repurchased shares is deducted from Total shareholders‘ equity through allocation to Capital in excess of stated value and Retained earnings .
Income Taxes	Income Taxes The Company accounts for income taxes using the asset and liability method. This approach requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the carrying amounts and the tax basis of assets and liabilities. The Company records a valuation allowance to reduce deferred tax assets to the amount management believes is more likely than not to be realized. The Company recognizes a tax benefit from uncertain tax positions in the financial statements only when it is more likely than not the position will be sustained upon examination by relevant tax authorities. The Company recognizes interest and penalties related to income tax matters in Income tax expense .
Earnings Per Share	Earnings Per Share Basic earnings per common share is calculated by dividing Net income by the weighted average number of common shares outstanding during the year. Diluted earnings per common share is calculated by adjusting weighted average outstanding shares, assuming conversion of all potentially dilutive stock options and awards.
Management Estimates	Management Estimates The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates, including estimates relating to assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates.
Recently Adopted and Recently Issued Accounting Standards	Recently Adopted Accounting Standards In February 2018, the FASB issued Accounting Standards Update (ASU) No. 2018-02, Income Statement — Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income . The standard allows for reclassification of stranded tax effects on items resulting from the Tax Cuts and Jobs Act (the “Tax Act”) from Accumulated other comprehensive income to Retained earnings . Tax effects unrelated to the Tax Act are released from Accumulated other comprehensive income using either the specific identification approach or the portfolio approach based on the nature of the underlying item. The Company early adopted the ASU in the third quarter of fiscal 2018. As a result of the adoption, Retained earnings decreased by $17 million , with a corresponding increase to Accumulated other comprehensive income due to the reduction in the corporate tax rate from 35% to 21%. Refer to Note 9 — Income Taxes for additional information on the impact of the Tax Act. In March 2016, the FASB issued ASU No. 2016-09, Compensation — Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting , which changes how companies account for certain aspects of share-based payment awards to employees. The Company adopted the ASU in the first quarter of fiscal 2018. The updated guidance requires excess tax benefits and deficiencies from share-based payment awards to be recorded in income tax expense in the income statement. Previously, excess tax benefits and deficiencies were recognized in shareholders’ equity on the balance sheet. This change is required to be applied prospectively. As a result of the adoption, during fiscal 2018, the Company recognized $230 million of excess tax benefits related to share-based payment awards in Income tax expense in the Consolidated Statements of Income. Additionally, ASU 2016-09 modified the classification of certain share-based payment activities within the statement of cash flows, which the Company applied retrospectively. As a result, for fiscal 2017 and fiscal 2016, the Company reclassified cash inflows of $177 million and $281 million , respectively, related to excess tax benefits from share-based payment awards, from Cash used by financing activities to Cash provided by operations , and reclassified cash outflows of $29 million and $22 million , for the respective periods, related to tax payments for the net settlement of share-based payment awards, from Cash provided by operations to Cash used by financing activities within the Consolidated Statements of Cash Flows. Recently Issued Accounting Standards In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities , which expands and refines hedge accounting for both financial and non-financial risk components, aligns the recognition and presentation of the effects of hedging instruments and hedge items in the financial statements, and includes certain targeted improvements to ease the application of current guidance related to the assessment of hedge effectiveness. The update to the standard is effective for the Company on June 1, 2019, with early adoption permitted in any interim period. The Company is currently evaluating the updated guidance, but does not expect the adoption to have a material impact on the Consolidated Financial Statements. In October 2016, the FASB issued ASU No. 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory . The updated guidance requires companies to recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. Income tax effects of intra-entity transfers of inventory will continue to be deferred until the inventory has been sold to a third party. The Company will adopt the standard on June 1, 2018, using a modified retrospective approach, with the cumulative effect of applying the new standard recognized in retained earnings at the date of adoption. Upon adoption, the Company will record a cumulative effect adjustment reducing Retained earnings , Deferred income taxes and other assets , and Prepaid expenses and other current assets by $507 million , $422 million and $45 million , respectively, and increasing Deferred income taxes and other liabilities by $40 million . In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) , which replaces existing lease accounting guidance. The new standard is intended to provide enhanced transparency and comparability by requiring lessees to record right-of-use assets and corresponding lease liabilities on the balance sheet. The new guidance will require the Company to continue to classify leases as either operating or financing, with classification affecting the pattern of expense recognition in the income statement. The Company will adopt the standard on June 1, 2019. The ASU is required to be applied using a modified retrospective approach at the beginning of the earliest period presented, with optional practical expedients. The Company continues to assess the effect the guidance will have on its existing accounting policies and the Consolidated Financial Statements and expects there will be an increase in assets and liabilities on the Consolidated Balance Sheets at adoption due to the recording of right-of-use assets and corresponding lease liabilities, which may be material. Refer to Note 15 — Commitments and Contingencies for information about the Company’s lease obligations. In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments — Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities . The updated guidance enhances the reporting model for financial instruments, which includes amendments to address aspects of recognition, measurement, presentation and disclosure. The update to the standard is effective for the Company beginning June 1, 2018. The Company does not expect the adoption to have a material impact on the Consolidated Financial Statements. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) , which replaces existing revenue recognition guidance. The updated guidance requires companies to recognize revenue in a way that depicts the transfer of 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. In addition, the new standard requires reporting companies to disclose the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. The Company will adopt the standard on June 1, 2018 using a modified retrospective approach with the cumulative effect of initially applying the new standard recognized in retained earnings at the date of adoption. While the Company does not expect the adoption of this standard to have a material impact on the Company’s net Revenues in the Consolidated Statements of Income, revenues for certain wholesale transactions and substantially all digital commerce sales will be recognized upon shipment rather than upon delivery to the customer. Accordingly, the Company will record a cumulative effect adjustment increasing Retained earnings by approximately $23 million on June 1, 2018. Additionally, provisions for post-invoice sales discounts, returns and miscellaneous claims will be recognized as accrued liabilities rather than as reductions to Accounts receivable, net ; and the estimated cost of inventory associated with the provision for sales returns will be recorded within Prepaid expenses and other current assets on the Consolidated Balance Sheets. The remaining provisions of the standard are not expected to have a material impact on the Company’s Consolidated Financial Statements.
