Organization, Consolidation and Presentation of Financial Statements [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Organization Super Micro Computer, Inc. (“Super Micro Computer”) was incorporated in 1993. Super Micro Computer is a global leader in server technology and green computing innovation. Super Micro Computer develops and provides high performance server solutions based upon an innovative, modular and open-standard architecture. Super Micro Computer has operations primarily in San Jose, California, the Netherlands, Taiwan, China and Japan. Basis of Presentation The condensed consolidated financial statements reflect the condensed consolidated balance sheets, results of operations, comprehensive income and cash flows of Super Micro Computer, Inc. and its wholly-owned subsidiaries (collectively, the “Company”). All intercompany accounts and transactions have been eliminated in consolidation. The unaudited condensed consolidated financial statements included herein have been prepared by the Company pursuant to the rules and regulations of the United States Securities and Exchange Commission (“SEC”) and include the accounts of the Company and its wholly-owned subsidiaries. Certain information and footnote disclosures normally included in financial statements prepared in accordance with United States generally accepted accounting principles have been condensed or omitted pursuant to such rules and regulations. These condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements for the fiscal year ended June 30, 2016 included in its Annual Report on Form 10-K, as filed with the SEC (the “Annual Report”). The unaudited condensed consolidated financial statements included herein reflect all adjustments, including normal recurring adjustments, which are, in the opinion of management, necessary for a fair presentation of the consolidated financial position, results of operations and cash flows for the periods presented. The condensed consolidated results of operations for the three months ended September 30, 2016 are not necessarily indicative of the results that may be expected for future quarters or for the fiscal year ending June 30, 2017 . The Company consolidates its investment in Super Micro Asia Science and Technology Park, Inc. as it is a variable interest entity and the Company is the primary beneficiary. The noncontrolling interest is presented as a separate component from the Company's equity in the equity section of the condensed consolidated balance sheets. Net income attributable to the noncontrolling interest is not presented separately in the condensed consolidated statements of operations and is included in the general and administrative expenses as the amount is not material for any of the fiscal periods presented. Fair Value of Financial Instruments The Company accounts for certain assets and liabilities at fair value. Accounts receivable and accounts payable are carried at cost, which approximates fair value due to the short maturity of these instruments. Cash equivalents and long-term investments are carried at fair value. Short-term and long-term debt is carried at amortized cost, which approximates its fair value based on borrowing rates currently available to the Company for loans with similar terms. The hierarchy below lists three levels of fair value based on the extent to which inputs used in measuring fair value are observable in the market. The Company categorizes each of its fair value measurements in one of these three levels based on the lowest level input that is significant to the fair value measurement in its entirety. These levels are: • Level 1 - Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities; • Level 2 - Quoted prices in markets that are not active or financial instruments for which all significant inputs are observable, either directly or indirectly; and • Level 3 - Prices or valuations that require inputs that are both significant to the fair value measurement and unobservable. Net Income Per Common Share The Company's basic net income per share is computed by dividing net income by the weighted-average number of shares of common stock outstanding during the period. Diluted net income per share is computed by dividing net income by the weighted-average number of shares of common stock outstanding during the period increased to include the number of additional shares of common stock that would have been outstanding if the potentially dilutive securities had been issued. Potentially dilutive securities include outstanding stock options and unvested restricted stock units (“RSUs”). Under the treasury stock method, an increase in the fair market value of the Company’s common stock results in a greater dilutive effect from outstanding stock options and RSUs. Additionally, the exercise of employee stock options and the vesting of restricted stock units results in a further dilutive effect on net income per share. Recently Issued Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued new accounting guidance, Revenue from Contracts with Customers , that replaces all current U.S. GAAP guidance on revenue, eliminates all industry-specific guidance and provides a unified model in determining when and how revenue is recognized. The core principle is that a company should recognize revenue to depict 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. Further, in March 2016, the FASB issued an amendment to the accounting guidance, Revenue from Contracts with Customers: Principal versus Agent Considerations (Reporting Revenue Gross versus Net) , which clarifies the implementation guidance for principal versus agent considerations. In April 2016, the FASB issued an amendment to the accounting guidance, Revenue from Contracts with Customers: Identifying Performance Obligations and Licensing , which clarifies the guidance related to identifying performance obligations and accounting for licenses of intellectual property. In May 2016, the FASB issued an amendment to the accounting guidance, Revenue from Contracts with Customers: Narrow-Scope Improvements and Practical Expedients , which clarifies the guidance related to collectibility and non-cash consideration, as well as provides practical expedients for the transition to the new accounting guidance. This guidance can be applied either retrospectively or as a cumulative-effect adjustment as of the date of adoption. Early adoption is permitted for annual periods beginning after December 15, 2016. The new standard is effective for the Company on July 1, 2018. The Company is currently evaluating the effect the guidance will have on its financial statement disclosures, results of operations and financial position. In April 2015, the FASB issued an amendment to the accounting guidance, Interest-Imputation of Interest: Simplifying the Presentation of Debt Issuance Costs. This amendment requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. In August 2015, the FASB issued an amendment to the accounting guidance, Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements. This amendment clarifies that an entity may defer and present debt issuance costs associated with line-of-credit arrangements as an asset and subsequently amortize the deferred debt issuance costs ratably over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. These amendments should be applied retrospectively to all prior periods presented in the financial statements. The Company adopted these amendments in the first quarter of fiscal year 2017. There was no material impact on its financial statement disclosures, results of operations and financial position. In July 2015, the FASB issued an amendment to the accounting guidance, Inventory: Simplifying the Measurement of Inventory . The amendment requires entities to measure inventory at the lower of cost and net realizable value thereby simplifying the current guidance under which an entity must measure inventory at the lower of cost or market. The amendment is effective for the Company on July 1, 2018. The Company is currently evaluating the effect the amendment to the guidance will have on its financial statement disclosures, results of operations and financial position. In February 2016, the FASB issued an amendment to the accounting guidance, Leases. The amendment will supersede the existing lease guidance, including on-balance sheet recognition of operating leases for lessees. This amendment should be applied using a modified retrospective approach and is effective for the Company on July 1, 2018. Early adoption is permitted. The Company is currently evaluating the effect the guidance will have on its financial statement disclosures, results of operations and financial position. In March 2016, the FASB issued new accounting guidance, Compensation—Stock Compensation: Improvements to Employee Share-Based Payment Accounting on the accounting for certain aspects of share-based payment to employees, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements as well as classification in the statement of cash flows. This guidance is effective for the Company on July 1, 2018. The Company is currently evaluating the effect the guidance will have on its financial statement disclosures, results of operations and financial position. In August 2016, the FASB issued an amendment to the accounting guidance, Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments. This amendment consists of eight provisions that provide guidance on the classification of certain cash receipts and cash payments. If practicable, this amendment should be applied using a retrospective transition method to each period presented. For the provisions that are impracticable to apply retrospectively, those provisions may be applied prospectively as of the earliest date practicable. This amendment is effective for the Company on July 1, 2019. Early adoption is permitted. The Company is currently evaluating the effect the guidance will have on its financial statement disclosures, results of operations and financial position.

Stock-based Compensation and Stockholders' Equity	Stock-based Compensation and Stockholders’ Equity Share Repurchase Program In July 2016, the Company’s Board of Directors adopted a program to repurchase from time to time at management’s discretion up to $100,000,000 of the Company’s common stock in the open market or in private transactions during the next twelve months at prevailing market prices. Repurchases will be made under the program using the Company’s own cash resources. This share repurchase program does not obligate the Company to acquire any particular amount of common stock, and it may be suspended at any time at the Company’s discretion. During the three months ended September 30, 2016 , the Company purchased 888,097 shares of the Company's common stock in the open market at a weighted average price of $20.79 for $18,461,000 . Equity Incentive Plan In January 2016, the Board of Directors approved the 2016 Equity Incentive Plan (the "2016 Plan") and reserved for issuance 4,700,000 shares of common stock for awards of stock options, stock appreciation rights, restricted stock, RSUs and other share-based awards. The 2016 Plan was approved by the stockholders of the Company and became effective on March 8, 2016. As of such date, 8,696,444 shares of common stock were reserved for outstanding awards under the Company's 2006 Equity Incentive Plan (the "2006" Plan). Such awards remained outstanding under the 2006 Plan following the adoption of the 2016 Plan, although no further awards will be granted under the 2006 Plan. Up to 2,800,000 shares subject to awards that remained outstanding under the 2006 Plan but that are forfeited in the future will become available for use under the 2016 Plan. In addition, 1,153,412 shares of common stock originally reserved for issuance under the 2006 Plan were cancelled upon the adoption of the 2016 Plan. Under the 2016 Plan, the exercise price per share for incentive stock options granted to employees owning shares representing more than 10% of the Company at the time of grant cannot be less than 110% of the fair value of the underlying share on grant date. Nonqualified stock options and incentive stock options granted to all other persons shall be granted at a price not less than 100% of the fair value. Options generally expire ten years after the date of grant. Stock options and RSUs generally vest over four years ; 25% at the end of one year and one sixteenth per quarter thereafter. As of September 30, 2016 , the Company had 3,884,570 shares available for future issuance under the 2016 Plan. Determining Fair Value The Company's fair value of RSUs is based on the closing market price of the Company's common stock on the date of grant. The Company estimates the fair value of stock options granted using the Black-Scholes-option-pricing formula and a single option award approach. This fair value is then amortized ratably over the requisite service periods of the awards, which is generally the vesting period. Expected Term—The Company’s expected term represents the period that the Company’s share-based awards are expected to be outstanding and was determined based on a combination of the Company's peer group and the Company's historical experience. Expected Volatility—Expected volatility is based on a combination of the Company's implied and historical volatility. Expected Dividend—The Black-Scholes valuation model calls for a single expected dividend yield as an input and the Company has no plans to pay dividends. Risk-Free Interest Rate—The risk-free interest rate used in the Black-Scholes valuation method is based on the United States Treasury zero coupon issues in effect at the time of grant for periods corresponding with the expected term of option. Estimated Forfeitures—The estimated forfeiture rate is based on the Company’s historical forfeiture rates and the estimate is revised in subsequent periods if actual forfeitures differ from the estimate. The fair value of stock option grants for the three months ended September 30, 2016 and 2015 was estimated on the date of grant using the Black-Scholes option pricing model with the following assumptions: Three Months Ended 2016 2015 Risk-free interest rate 1.12 % 1.57 % Expected term 5.38 years 5.33 years Dividend yield — % — % Volatility 49.64 % 47.06 % Weighted-average fair value $ 9.29 $ 11.64 The following table shows total stock-based compensation expense included in the condensed consolidated statements of operations for the three months ended September 30, 2016 and 2015 (in thousands): Three Months Ended 2016 2015 Cost of sales $ 309 $ 240 Research and development 2,908 2,402 Sales and marketing 478 404 General and administrative 809 830 Stock-based compensation expense before taxes 4,504 3,876 Income tax impact (1,286 ) (285 ) Stock-based compensation expense, net $ 3,218 $ 3,591 The cash flows resulting from the tax benefits for tax deductions resulting from the exercise of stock options and vesting of RSUs in excess of the compensation expense recorded for those share-based awards (excess tax benefits) issued or modified since July 1, 2006 are classified as cash from financing activities. Excess tax benefits for stock options issued prior to July 1, 2006 are classified as cash from operating activities. The Company had $32,000 of shortfalls recorded in additional paid-in capital in the three months ended September 30, 2016 , and the Company had $714,000 of excess tax benefits recorded in additional paid-in capital in the three months ended September 30, 2015 . The Company had excess tax benefits classified as cash provided by financing activities of $302,000 and $134,000 in the three months ended September 30, 2016 and 2015 , respectively, for share-based awards issued since July 1, 2006. As of September 30, 2016 , the Company’s total unrecognized compensation cost related to non-vested share-based awards granted to employees and non-employee directors was $37,947,000 , which will be recognized over a weighted-average vesting period of approximately 2.34 years. Stock Option Activity The following table summarizes stock option activity during the three months ended September 30, 2016 under all plans: Options Outstanding Weighted Average Exercise Price per Share Weighted Average Remaining Contractual Term (in Years) Aggregate Intrinsic Value (in thousands) Balance as of June 30, 2016 (7,495,131 shares exercisable at weighted average exercise price of $13.35 per share) 8,960,867 $ 14.88 Granted (weighted average fair value of $9.29) 127,620 $ 20.54 Exercised (257,453 ) $ 11.41 Forfeited (12,854 ) $ 19.78 Balance as of September 30, 2016 8,818,180 $ 15.06 5.09 $ 79,505 Options vested and expected to vest at September 30, 2016 8,744,510 $ 14.97 5.06 $ 79,405 Options vested and exercisable at September 30, 2016 7,494,049 $ 13.62 4.55 $ 75,717 The total pretax intrinsic value of options exercised was $2,652,000 and $2,741,000 during the three months ended September 30, 2016 and 2015 , respectively. RSU Activity The Company grants RSUs to certain employees as part of its regular employee equity compensation review program as well as to selected new hires. RSUs are share awards that entitle the holder to receive freely tradable shares of the Company's common stock upon vesting and settlement. The following table summarizes RSUs activity during the three months ended September 30, 2016 under all plans: RSUs Outstanding Weighted Average Grant-Date Fair Value per Share Aggregate Intrinsic Value (in thousands) Balance as of June 30, 2016 926,983 $ 30.23 Granted 214,370 $ 20.54 Released (86,445 ) $ 28.36 Forfeited (29,831 ) $ 28.43 Balance as of September 30, 2016 1,025,077 $ 28.41 $ 23,956 The total pretax intrinsic value of RSUs vested was $1,852,000 and $547,000 for the three months ended September 30, 2016 and 2015 , respectively. In the three months ended September 30, 2016 and 2015, upon vesting, 86,445 and 20,199 shares of RSUs were partially net share-settled such that the Company withheld 30,799 and 7,232 shares with value equivalent to the employees' minimum statutory obligation for the applicable income and other employment taxes, and remitted the cash to the appropriate taxing authorities, respectively. The total shares withheld were based on the value of the RSUs on their respective vesting dates as determined by the Company's closing stock price. Total payments for the employees' tax obligations to taxing authorities were $660,000 and 196,000 during the three months ended September 30, 2016 and 2015, respectively, and are reflected as a financing activity within the condensed consolidated statements of cash flows. These net-share settlements had the effect of share repurchases by the Company as they reduced and retired the number of shares that would have otherwise been issued as a result of the vesting and did not represent an expense to the Company. Pursuant to the terms of the 2016 Plan, shares withheld in connection with net-share settlements are returned to the 2016 Plan and are available for future grants under the 2016 Plan.

Ablecom’s ownership of Compuware is below 50% but Compuware remains a related party as Ablecom still has significant influence over its operations. Ablecom’s chief executive officer, Steve Liang, is the brother of Charles Liang, the Company’s President, Chief Executive Officer and Chairman of the Board of Directors. Ablecom owns approximately 0.6% of the Company’s common stock. Charles Liang and his wife, also an officer of the Company, collectively own approximately 10.5% of Ablecom, while Steve Liang and other family members own approximately 36.0% of Ablecom at September 30, 2016 . The Company has product design and manufacturing services agreements (“product design and manufacturing agreements”) and a distribution agreement (“distribution agreement”) with Ablecom. Under the product design and manufacturing agreements, the Company outsources a portion of its design activities and a significant part of its manufacturing of components such as server chassis to Ablecom. Ablecom agrees to design products according to the Company’s specifications. Additionally, Ablecom agrees to build the tools needed to manufacture the products. The Company has agreed to pay for Ablecom's cost of chassis and related product tooling and engineering services and will pay for those items when the work has been completed. Under the distribution agreement, Ablecom purchases server products from the Company for distribution in Taiwan. The Company believes that the pricing and terms under the distribution agreement are similar to the pricing and terms of distribution arrangements the Company has with similar, third party distributors. Ablecom’s net sales to the Company and its net sales of the Company’s products to others comprise a substantial majority of Ablecom’s net sales. The Company purchased products from Ablecom totaling $50,205,000 and $59,261,000 , and sold products to Ablecom totaling $3,342,000 and $5,220,000 for the three months ended September 30, 2016 and 2015 , respectively. Amounts owed to the Company by Ablecom as of September 30, 2016 and June 30, 2016 were $7,251,000 and $4,678,000 , respectively. Amounts owed to Ablecom by the Company as of September 30, 2016 and June 30, 2016 were $38,290,000 and $39,152,000 , respectively. For the three months ended September 30, 2016 , the Company paid Ablecom the majority of invoiced dollars between 47 and 77 days of invoice date. For the three months ended September 30, 2016 and 2015 , the Company paid $1,745,000 and $1,162,000 , respectively, for tooling assets and miscellaneous costs to Ablecom. The Company’s exposure to loss as a result of its involvement with Ablecom is limited to (a) potential losses on its purchase orders in the event of an unforeseen decline in the market price and/or demand of the Company’s products such that the Company incurs a loss on the sale or cannot sell the products and (b) potential losses on outstanding accounts receivable from Ablecom in the event of an unforeseen deterioration in the financial condition of Ablecom such that Ablecom defaults on its payable to the Company. Outstanding purchase orders with Ablecom were $77,369,000 and $62,782,000 at September 30, 2016 and June 30, 2016 , respectively, representing the maximum exposure to loss relating to (a) above. The Company does not have any direct or indirect guarantees of losses of Ablecom. In May 2012, the Company and Ablecom jointly established Super Micro Asia Science and Technology Park, Inc. ("Management Company") in Taiwan to manage the common areas shared by the Company and Ablecom for their separately constructed manufacturing facilities. Each company contributed $168,000 and owns 50% of the Management Company. Although the operations of the Management Company are independent of the Company, through governance rights, the Company has the ability to direct the Management Company's business strategies. Therefore, the Company has concluded that the Management Company is a variable interest entity of the Company as the Company is the primary beneficiary of the Management Company. The accounts of the Management Company are consolidated with the accounts of the Company, and a noncontrolling interest has been recorded for the Ablecom's interests in the net assets and operations of the Management Company. In the three months ended September 30, 2016 and 2015 , $5,000 and $2,000 of net income attributable to Ablecom's interest was included in the Company's general and administrative expenses in the condensed consolidated statements of operations.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company recorded provisions for income taxes of $6,369,000 and $7,504,000 for the three months ended September 30, 2016 and 2015 , respectively. The effective tax rate was 32.0% and 35.4% for the three months ended September 30, 2016 and 2015 , respectively. The effective tax rate for the three months ended September 30, 2016 is estimated to be lower than the federal statutory rate primarily due to the benefit from U.S. federal research and development ("R&D") tax credit and domestic production activities deduction. As of September 30, 2016 , the Company had a liability for gross unrecognized tax benefits of $17,080,000 , substantially all of which, if recognized, would affect the Company's effective tax rate. During the three months ended September 30, 2016 , there were no material changes in the total amount of the liability for gross unrecognized tax benefits. The Company’s policy is to include interest and penalties related to unrecognized tax benefits within the provision for taxes on the condensed consolidated statements of operations. As of September 30, 2016 , the Company had accrued $1,524,000 of interest and penalties relating to unrecognized tax benefits. The Company is subject to United States federal income tax as well as income taxes in many state and foreign jurisdictions. The Company's 2012 and 2013 federal tax returns are currently under the IRS examination. The Company has responded to Information Document Requests ("IDRs"), issued by the Internal Revenue Service ("IRS"). No adjustment has been proposed by the IRS as of September 30, 2016 . The Company is also currently under audit in Taiwan. The Taiwan Tax Authority issued income tax assessments for tax years 2013 and 2014 related to the local income tax exemption regime which the Company has participated in. The Company is currently in the process of appealing the assessments. While management believes that the Company has adequately provided reserves for all uncertain tax positions, amounts asserted by tax authorities could be greater or less than the Company’s current position. Accordingly, the Company’s provision on federal, state and foreign tax related matters to be recorded in the future may change as revised estimates are made or the underlying matters are settled or otherwise resolved. The federal statute of limitations remain open in general for tax years 2012 through 2015. The state statute of limitations remain open in general for tax years 2011 through 2015. The statute of limitations in major foreign jurisdictions remain open for examination in general for tax years 2009 through 2015. The Company does not expect its unrecognized tax benefits to change materially over the next 12 months.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The condensed consolidated financial statements reflect the condensed consolidated balance sheets, results of operations, comprehensive income and cash flows of Super Micro Computer, Inc. and its wholly-owned subsidiaries (collectively, the “Company”). All intercompany accounts and transactions have been eliminated in consolidation. The unaudited condensed consolidated financial statements included herein have been prepared by the Company pursuant to the rules and regulations of the United States Securities and Exchange Commission (“SEC”) and include the accounts of the Company and its wholly-owned subsidiaries. Certain information and footnote disclosures normally included in financial statements prepared in accordance with United States generally accepted accounting principles have been condensed or omitted pursuant to such rules and regulations. These condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements for the fiscal year ended June 30, 2016 included in its Annual Report on Form 10-K, as filed with the SEC (the “Annual Report”). The unaudited condensed consolidated financial statements included herein reflect all adjustments, including normal recurring adjustments, which are, in the opinion of management, necessary for a fair presentation of the consolidated financial position, results of operations and cash flows for the periods presented. The condensed consolidated results of operations for the three months ended September 30, 2016 are not necessarily indicative of the results that may be expected for future quarters or for the fiscal year ending June 30, 2017 . The Company consolidates its investment in Super Micro Asia Science and Technology Park, Inc. as it is a variable interest entity and the Company is the primary beneficiary. The noncontrolling interest is presented as a separate component from the Company's equity in the equity section of the condensed consolidated balance sheets. Net income attributable to the noncontrolling interest is not presented separately in the condensed consolidated statements of operations and is included in the general and administrative expenses as the amount is not material for any of the fiscal periods presented.
Fair Value of Financial Instruments	Fair Value of Financial Instruments The Company accounts for certain assets and liabilities at fair value. Accounts receivable and accounts payable are carried at cost, which approximates fair value due to the short maturity of these instruments. Cash equivalents and long-term investments are carried at fair value. Short-term and long-term debt is carried at amortized cost, which approximates its fair value based on borrowing rates currently available to the Company for loans with similar terms. The hierarchy below lists three levels of fair value based on the extent to which inputs used in measuring fair value are observable in the market. The Company categorizes each of its fair value measurements in one of these three levels based on the lowest level input that is significant to the fair value measurement in its entirety. These levels are: • Level 1 - Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities; • Level 2 - Quoted prices in markets that are not active or financial instruments for which all significant inputs are observable, either directly or indirectly; and • Level 3 - Prices or valuations that require inputs that are both significant to the fair value measurement and unobservable.
Net Income Per Common Share	Net Income Per Common Share The Company's basic net income per share is computed by dividing net income by the weighted-average number of shares of common stock outstanding during the period. Diluted net income per share is computed by dividing net income by the weighted-average number of shares of common stock outstanding during the period increased to include the number of additional shares of common stock that would have been outstanding if the potentially dilutive securities had been issued. Potentially dilutive securities include outstanding stock options and unvested restricted stock units (“RSUs”). Under the treasury stock method, an increase in the fair market value of the Company’s common stock results in a greater dilutive effect from outstanding stock options and RSUs. Additionally, the exercise of employee stock options and the vesting of restricted stock units results in a further dilutive effect on net income per share.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued new accounting guidance, Revenue from Contracts with Customers , that replaces all current U.S. GAAP guidance on revenue, eliminates all industry-specific guidance and provides a unified model in determining when and how revenue is recognized. The core principle is that a company should recognize revenue to depict 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. Further, in March 2016, the FASB issued an amendment to the accounting guidance, Revenue from Contracts with Customers: Principal versus Agent Considerations (Reporting Revenue Gross versus Net) , which clarifies the implementation guidance for principal versus agent considerations. In April 2016, the FASB issued an amendment to the accounting guidance, Revenue from Contracts with Customers: Identifying Performance Obligations and Licensing , which clarifies the guidance related to identifying performance obligations and accounting for licenses of intellectual property. In May 2016, the FASB issued an amendment to the accounting guidance, Revenue from Contracts with Customers: Narrow-Scope Improvements and Practical Expedients , which clarifies the guidance related to collectibility and non-cash consideration, as well as provides practical expedients for the transition to the new accounting guidance. This guidance can be applied either retrospectively or as a cumulative-effect adjustment as of the date of adoption. Early adoption is permitted for annual periods beginning after December 15, 2016. The new standard is effective for the Company on July 1, 2018. The Company is currently evaluating the effect the guidance will have on its financial statement disclosures, results of operations and financial position. In April 2015, the FASB issued an amendment to the accounting guidance, Interest-Imputation of Interest: Simplifying the Presentation of Debt Issuance Costs. This amendment requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. In August 2015, the FASB issued an amendment to the accounting guidance, Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements. This amendment clarifies that an entity may defer and present debt issuance costs associated with line-of-credit arrangements as an asset and subsequently amortize the deferred debt issuance costs ratably over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. These amendments should be applied retrospectively to all prior periods presented in the financial statements. The Company adopted these amendments in the first quarter of fiscal year 2017. There was no material impact on its financial statement disclosures, results of operations and financial position. In July 2015, the FASB issued an amendment to the accounting guidance, Inventory: Simplifying the Measurement of Inventory . The amendment requires entities to measure inventory at the lower of cost and net realizable value thereby simplifying the current guidance under which an entity must measure inventory at the lower of cost or market. The amendment is effective for the Company on July 1, 2018. The Company is currently evaluating the effect the amendment to the guidance will have on its financial statement disclosures, results of operations and financial position. In February 2016, the FASB issued an amendment to the accounting guidance, Leases. The amendment will supersede the existing lease guidance, including on-balance sheet recognition of operating leases for lessees. This amendment should be applied using a modified retrospective approach and is effective for the Company on July 1, 2018. Early adoption is permitted. The Company is currently evaluating the effect the guidance will have on its financial statement disclosures, results of operations and financial position. In March 2016, the FASB issued new accounting guidance, Compensation—Stock Compensation: Improvements to Employee Share-Based Payment Accounting on the accounting for certain aspects of share-based payment to employees, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements as well as classification in the statement of cash flows. This guidance is effective for the Company on July 1, 2018. The Company is currently evaluating the effect the guidance will have on its financial statement disclosures, results of operations and financial position. In August 2016, the FASB issued an amendment to the accounting guidance, Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments. This amendment consists of eight provisions that provide guidance on the classification of certain cash receipts and cash payments. If practicable, this amendment should be applied using a retrospective transition method to each period presented. For the provisions that are impracticable to apply retrospectively, those provisions may be applied prospectively as of the earliest date practicable. This amendment is effective for the Company on July 1, 2019. Early adoption is permitted. The Company is currently evaluating the effect the guidance will have on its financial statement disclosures, results of operations and financial position.
