Organization Consolidation And Presentation Of Financial Statements [Abstract]

Description of Business and Basis of Presentation

1.	Description of Business and Basis of Presentation

Extreme Networks, Inc. (“Extreme Networks” or the “Company”) is a leading provider of network infrastructure equipment and markets its products primarily to business, governmental, health care, service provider, and educational customers with a focus on large corporate enterprises and metropolitan service providers on a global basis. The Company conducts its sales and marketing activities on a worldwide basis through distributors, resellers and the Company’s field sales organization. Extreme Networks was incorporated in California in 1996 and reincorporated in Delaware in 1999.

The unaudited condensed consolidated financial statements of Extreme Networks included herein have been prepared under the rules and regulations of the Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted under such rules and regulations. The condensed consolidated balance sheet at June 30, 2015 was derived from audited financial statements as of that date but does not include all disclosures required by generally accepted accounting principles for complete financial statements. These interim financial statements and notes should be read in conjunction with the Company’s audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended June 30, 2015.

The unaudited condensed consolidated financial statements reflect all adjustments, consisting only of normal recurring adjustments that, in the opinion of management, are necessary for a fair presentation of the results of operations and cash flows for the interim periods presented and the financial condition of Extreme Networks at March 31, 2016 The results of operations for the three and nine months ended March 31, 2016 are not necessarily indicative of the results that may be expected for fiscal 2016 or any future periods.

Fiscal Year

The Company uses a fiscal calendar year ending on June 30. All references herein to "fiscal 2016" or "2016" represent the fiscal year ending June 30, 2016.

Principles of Consolidation

The consolidated financial statements include the accounts of Extreme Networks and its wholly-owned subsidiaries. All inter-company accounts and transactions have been eliminated.

Accounting Estimates

The preparation of financial statements and related disclosures in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Estimates are used for, but are not limited to, the accounting for the allowances for doubtful accounts and sales returns, determining the fair value of acquired assets and assumed liabilities, estimated selling prices, inventory valuation and purchase commitments, depreciation and amortization, impairment of long-lived assets including goodwill, warranty accruals, restructuring liabilities, measurement of share-based compensation costs and income taxes. Actual results could differ materially from these estimates.

The Company predominantly uses the United States Dollar as its functional currency. The functional currency for certain of its foreign subsidiaries is the local currency. For those subsidiaries that operate in a local currency functional environment, all assets and liabilities are translated to United States Dollars at current month end rates of exchange; and revenue and expenses are translated using the monthly average rate.

Recently Issued Accounting Pronouncements

3.	Recently Issued Accounting Pronouncements

For a description of recently issued accounting pronouncements, see Note 4, Recently Issued Accounting Pronouncements, to the consolidated financial statements included in the Company's Annual report on Form 10-K for the fiscal year ended June 30, 2015. The following are accounting pronouncements issued that may materially affect the Company's financial statements since the filing of the Annual report on Form 10-K.

In March 2016, the FASB issued ASU 2016-09, Compensation – Stock Compensation (Topic 718). ASU 2016-09 identifies areas for simplification involving several aspects of accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, an option to recognize gross stock compensation expense with actual forfeitures recognized as they occur, as well as certain classifications on the statement of cash flows. The Company is currently assessing the impact that adopting this new accounting standard will have on its consolidated financial statements and footnote disclosures.

In March 2016, the FASB issued ASU 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net). ASU 2016-08 clarifies the implementation guidance on principal versus agent considerations. The guidance includes indicators to assist an entity in determining whether it controls a specified good or service before it is transferred to the customers. The Company is currently assessing the impact that adopting this new accounting standard will have on its consolidated financial statements and footnote disclosures.

In March 2016, the FASB issued ASU 2016-06, Derivatives and Hedging (Topic 815) – Contingent Put and Call Options in Debt Instruments, which will reduce diversity of practice in identifying embedded derivatives in debt instruments. ASU 2016-06 clarifies that the nature of an exercise contingency is not subject to the “clearly and closely” criteria for purposes of assessing whether the call or put option must be separated from the debt instrument and accounted for separately as a derivative. The Company is currently assessing the impact that adopting this new accounting standard will have on its consolidated financial statements and footnote disclosures.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). ASU 2016-02 requires the identification of arrangements that should be accounted for as leases by lessees. In general, for lease arrangements exceeding a twelve month term, these arrangements must now be recognized as assets and liabilities on the balance sheet of the lessee. Under ASU 2016-02, a right-of-use asset and lease obligation will be recorded for all leases, whether operating or financing, while the income statement will reflect lease expense for operating leases and amortization/interest expense for financing leases. The balance sheet amount recorded for existing leases at the date of adoption of ASU 2016-02 must be calculated using the applicable incremental borrowing rate at the date of adoption. In addition, ASU 2016-02 requires the use of the modified retrospective method, which will require adjustment to all comparative periods presented in the consolidated financial statements. The Company is currently assessing the impact that adopting this new accounting standard will have on its consolidated financial statements and footnote disclosures.

In January 2016, the FASB issued ASU 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities, which provides guidance for the recognition, measurement, presentation, and disclosure of financial assets and liabilities. The Company is currently assessing the impact that adopting this new accounting standard will have on its consolidated financial statements and footnote disclosures.

In November 2015, the FASB issued Accounting Standards Update No. 2015-17 (“ASU 2015-17”), Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes. Current GAAP requires an entity to separate deferred income tax liabilities and assets into current and noncurrent amounts in a classified statement of financial position. To simplify the presentation of deferred income taxes, ASU 2015-17 requires that deferred tax liabilities and assets be classified as noncurrent in a classified statement of financial position. The current requirement that deferred tax liabilities and assets of a tax-paying component of an entity be offset and presented as a single amount is not affected by the amendments in this Update. The amendments in this Update are effective for financial statements issued for annual periods beginning after December 15, 2016, and interim periods within those annual periods. Earlier application is permitted for all entities as of the beginning of an interim or annual reporting period and the amendments for ASU-2015-17 can be applied retrospectively or prospectively. The adoption of this guidance is not expected to have a material impact upon our financial statements and footnote disclosures. This guidance will become effective for us beginning with our fiscal year 2018.

In April 2015, the FASB issued Accounting Standards Update No. 2015-03 (“ASU 2015-03”) - Simplifying the Presentation of Debt Issuance Costs, which 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. ASU 2015-03 requires retrospective adoption and will be effect for annual and interim periods in fiscal years beginning after December 15, 2015. The Company does not believe adoption of this standard will have a material impact on our financial statements and footnote disclosures. This guidance will become effective for us beginning with our fiscal year 2017.

Balance Sheet Accounts

4.	Balance Sheet Accounts

Cash and Cash Equivalents

The following is a summary of cash and available-for-sale securities (in thousands):

	March 31, 2016		June 30, 2015
Cash	$	83,564	$	71,455

Cash equivalents	$	4,770	$	4,770
Total available-for-sale	$	4,770	$	4,770

Total cash, cash equivalents and available for sale securities	$	88,334	$	76,225

The Company considers highly liquid investments with maturities of three months or less at the date of purchase to be cash equivalents. Investments with original maturities of greater than three months, but less than one year at the balance sheet date are classified as short-term investments.

Inventory Valuation

The Company’s inventory balances as of March 31, 2016 and June 30, 2015 were $$52.8 million and $58.0 million, respectively. The Company values its inventory at lower of cost or market. Cost is computed using standard cost, which approximates actual cost, on a first-in, first-out basis. The Company has established inventory allowances primarily determined by the age of inventory or when conditions exist that suggest that inventory may be in excess of anticipated demand or is obsolete based upon assumptions about future demand. At the point of the loss recognition, a new, lower-cost basis for that inventory is established, and subsequent changes in facts and circumstances do not result in the restoration or increase in that newly established cost basis. Any written down or obsolete inventory subsequently sold has not had a material impact on gross margin for any of the periods disclosed.

The following is a summary of our inventory by category (in thousands):

During fiscal 2015, the Company amended its credit agreement which provides for a five-year revolving credit facility for up to $50.0 million (the “Revolving Facility”) and a $65.0 million five-year term loan (the “Term Loan”) and together with the Revolving Facility the (“Senior Secured Credit Facilities, as amended”).

The Senior Secured Credit Facilities, as amended contains, among others, certain financial covenants that require the Company to maintain defined minimum financial ratios which may limit the Company’s availability to borrowings under the Revolving Facility. As of March 31, 2016, the Company had $39.0 million of availability under the Revolving Facility and is in compliance with its covenants.

The Company had $1.0 million of outstanding letters of credit as of March 31, 2016

Guarantees and Product Warranties

Networking products may contain undetected hardware or software errors when new products or new versions or updates of existing products are released to the marketplace. In the past, we had experienced such errors in connection with products and product updates. The Company’s standard hardware warranty period is typically 12 months from the date of shipment to end-users and 90 days for software. For certain access products, the Company offers a limited lifetime hardware warranty commencing on the date of shipment from the Company and ending five (5) years following the Company’s announcement of the end of sale of such product. Upon shipment of products to its customers, the Company estimates expenses for the cost to repair or replace products that may be returned under warranty and accrue a liability in cost of product revenue for this amount. The determination of the Company’s warranty requirements is based on actual historical experience with the product or product family, estimates of repair and replacement costs and any product warranty problems that are identified after shipment. The Company estimates and adjusts these accruals at each balance sheet date in accordance with changes in these factors.

Upon issuance of a standard product warranty, the Company discloses and recognizes a liability for the obligations it assumes under the product warranty. The following table summarizes the activity related to the Company’s product warranty liability during the three and nine months ended March 31, 2016 and 2015 (in thousands):

	Three Months Ended						Nine Months Ended

To facilitate sales of its products in the normal course of business, the Company indemnifies its resellers and end-user customers with respect to certain matters. The Company has agreed to hold the customer harmless against losses arising from a breach of intellectual property infringement or other claims made against certain parties. These agreements may limit the time within which an indemnification claim can be made and the amount of the claim. It is not possible to estimate the maximum potential amount under these indemnification agreements due to the limited history of prior indemnification claims and the unique facts and circumstances involved in each particular agreement. Historically, payments made by the Company under these agreements have not had a material impact on its operating results or financial position.

Advertising

Cooperative advertising expenses are recorded as marketing expenses to the extent that an advertising benefit separate from the revenue transaction can be identified and the cash paid does not exceed the fair value of that advertising benefit received. Cooperative advertising obligations with customers are accrued and the costs expensed at the time the related revenue is recognized. If the Company does not meet the criteria for recognizing such cooperative advertising obligations as marketing expense, the costs are recorded as a reduction of revenue. All other advertising costs are expensed as incurred. Advertising expenses for three and nine months ended March 31, 2016 and 2015, were immaterial.

Concentrations

The Company may be subject to concentration of credit risk as a result of certain financial instruments consisting of accounts receivable and short-term investments. The Company does not invest an amount exceeding 10% of its combined cash or cash equivalents in the securities of any one obligor or maker, except for obligations of the United States government, obligations of United States government agencies and money market accounts.

The Company performs ongoing credit evaluations of its customers and generally does not require collateral in exchange for credit.

The following table sets forth major customers accounting for 10% or more of our net revenue:

Fair Value Disclosures [Abstract]

Fair Value Measurements

5.	Fair Value Measurements

A three-tier fair value hierarchy is utilized to prioritize the inputs used in measuring fair value. The hierarchy gives the highest priority to quoted prices in active markets (Level 1) and the lowest priority to unobservable inputs (Level 3). The three levels are defined as follows:

Level 1 Inputs - unadjusted quoted prices in active markets for identical assets or liabilities;

Level 2 Inputs - quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument; and

Level 3 Inputs - unobservable inputs reflecting the Company's own assumptions in measuring the asset or liability at fair value.

The Company did not hold any financial liabilities that required measurement at fair value on a recurring basis. The following table presents the Company’s fair value hierarchy for its financial assets measured at fair value on a recurring basis (in thousands):

March 31, 2016	Level 1		Level 2		Level 3		Total
Assets
Investments:
Money market funds	$	4,770	$	—	$	—	$	4,770
Total	$	4,770	$	—	$	—	$	4,770

June 30, 2015	Level 1		Level 2		Level 3		Total
Assets
Investments:
Money market funds	$	4,770	$	—	$	—	$	4,770
Total	$	4,770	$	—	$	—	$	4,770

Level 2 investments: The Company does not hold any level 2 investments.

The Company includes U.S. government and sovereign obligations, most government agency securities, investment-grade corporate bonds, and state, municipal and provincial obligations for which quoted prices are available as Level 2. There were no transfers of assets or liabilities between Level 1 and Level 2 for the periods presented.

The fair value of the borrowings under the Senior Secured Credit Facility, as amended is estimated based on valuations provided by alternative pricing sources supported by observable inputs which is considered Level 2. Due to the short duration until maturity of the credit facility, the fair value approximates the carrying amount of the Company’s indebtedness of $58.8 million and $66.9 million as of March 31, 2016 and June 30, 2015, respectively.

Level 3 investments: The Company does not hold any level 3 investments.

Certain of the Company's assets, including intangible assets and goodwill are measured at fair value on a non-recurring basis if impairment is indicated. There were no impairments recorded for the three and nine months ended March 31, 2016 or 2015.

- Definition

The entire disclosure for the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments as well as disclosures related to the fair value of non-financial assets and liabilities. Such disclosures about the financial instruments, assets, and liabilities would include: (1) the fair value of the required items together with their carrying amounts (as appropriate); (2) for items for which it is not practicable to estimate fair value, disclosure would include: (a) information pertinent to estimating fair value (including, carrying amount, effective interest rate, and maturity, and (b) the reasons why it is not practicable to estimate fair value; (3) significant concentrations of credit risk including: (a) information about the activity, region, or economic characteristics identifying a concentration, (b) the maximum amount of loss the entity is exposed to based on the gross fair value of the related item, (c) policy for requiring collateral or other security and information as to accessing such collateral or security, and (d) the nature and brief description of such collateral or security; (4) quantitative information about market risks and how such risks are managed; (5) for items measured on both a recurring and nonrecurring basis information regarding the inputs used to develop the fair value measurement; and (6) for items presented in the financial statement for which fair value measurement is elected: (a) information necessary to understand the reasons for the election, (b) discussion of the effect of fair value changes on earnings, (c) a description of [similar groups] items for which the election is made and the relation thereof to the balance sheet, the aggregate carrying value of items included in the balance sheet that are not eligible for the election; (7) all other required (as defined) and desired information.

Stock Awards

Stock awards may be granted under the 2013 Equity Incentive Plan (the “2013 Plan”) on terms approved by the Compensation Committee of the Board of Directors. Stock awards generally provide for the issuance of restricted stock units (including performance or market-based restricted stock units) which vest over a fixed period of time or based upon the satisfaction of certain ;performance criteria.

The weighted-average grant-date fair value of options granted during the nine months ended March 31, 2016 was $1.59. The weighted-average grant-date fair value of options granted during the three and nine months ended March 31, 2015 was $1.34 and $1.91, respectively.

The weighted-average fair value of shares granted under the Company’s 2014 ESPP during the three and nine months ended March 31, 2016 was $1.88 and $1.93, respectively. The weighted-average fair value of shares granted under the Company’s 2014 ESPP and 1999 ESPP during the three and nine months ended March 31, 2015 was $0.59 and $1.02, respectively.

The Company uses the straight-line method for expense attribution, and the Company estimates forfeitures and only recognizes expense for those shares expected to vest. The Company’s estimated forfeiture rate for fiscal 2016 is based on the Company’s historical forfeiture experience and is 13% for non-executives and 19% for executives.

The fair value of each stock option grant under the Company's 2013 Plan and 2005 Equity Incentive Plan is estimated on the date of grant using the Black-Scholes-Merton option valuation model with the weighted average assumptions noted in the following table. The Company uses the Monte-Carlo simulation model to determine the fair value and the derived service period of stock awards with market conditions, on the date of the grant. The expected term of options granted is derived from historical data on employee exercise and post-vesting employment termination behavior. The risk-free rate is based upon the estimated life of the option and is based on the U.S. Treasury yield curve in effect at the time of grant. Expected volatility is based on a blended rate of the implied volatilities from traded options on the Company’s stock and historical volatility on the Company’s stock.

The fair value of each share purchase option under the Company's 2014 ESPP and 1999 ESPP is estimated on the date of grant using the Black-Scholes-Merton option valuation model with the weighted average assumptions noted in the following table. The expected term of the 2014 ESPP and the 1999 ESPP represents the term of the offering period of each option. The risk-free rate is based upon the estimated life and is based on the U.S. Treasury yield curve in effect at the time of grant. Expected volatility is based on a blended rate of the implied volatilities from traded options and historical volatility on the Company’s stock.

Restructuring And Related Activities [Abstract]

Restructuring Charges

7.	Restructuring Charges

As of March 31, 2016, restructuring liabilities were $4.2 million and consisted of obligations for severance benefits, contract termination and other expenses. During the three and nine months ended March 31, 2016, the Company recorded restructuring charges of $1.4 million and $10.0 million, respectively. Included in the restructuring charges were offsets for future sub-leasing income. The Company has estimated the sub-lease income based on its existing leases agreement, as well the real estate market conditions at the respective locations. The Company also factored into its estimate the time for a sub-lease tenant to enter into an agreement and complete any improvements. The Company will reevaluate any sub-lease income on a regular basis and adjust the accrual as necessary if and when facts should change.

Fiscal 2015 Restructuring: Phase One

During the fourth quarter of fiscal 2015, we reduced costs through targeted restructuring activities intended to reduce operating costs and realign our organization in the current competitive environment. We initiated a plan to reduce our worldwide headcount by more than 225 employees, primarily in sales and marketing, as well as research and development, consolidate specific global administrative functions, and shift certain operating costs to lower cost regions in the United States, among other actions.

Phase Two

During fiscal 2016, we continued our initiative to realign our operations with a second phase by abandoning excess facilities, primarily in San Jose, California; Salem, New Hampshire; Research Triangle Park, North Carolina and Shannon, Ireland. The abandoned facilities represented approximately 29% of the floor space in the aggregate at these locations and included general office and warehouse space. There may be additional abandonments of excess facilities in future periods as we further align our organization to our business and operational needs.

During the first quarter of fiscal 2016, in conjunction with the exiting of facilities noted above, the Company recorded restructuring charges of $5.6 million including $5.4 million for excess facility charges and adjustments to service benefits of $0.2 million. Excess facilities charges included $4.1 million of accrued lease costs pertaining to the estimated future obligations for non-cancelable lease payments for excess facilities and accelerated depreciation of leasehold improvements in the amount of $1.3 million. This charge is reflected in "Restructuring charge, net of reversals" in the condensed consolidated statements of operations.

During the second quarter of fiscal 2016, in conjunction with the exiting of the facilities noted above, the Company incurred restructuring charges of $3.0 million including $2.9 million in excess facilities charges related to amending its lease in North Carolina, thereby reducing it floor space by 36%, and adjustments to severance benefits of $0.2 million. Excess facilities charges included accelerated depreciation of leasehold improvements in the amount of $1.9 million and contract termination charges and professional fees of $1.0 million. This charge is reflected in "Restructuring charge, net of reversals" in the condensed consolidated statements of operations.

During the third quarter of fiscal 2016, in conjunction with the exiting of facilities noted above, the Company incurred restructuring charges of $1.4 million. Excess facilities charges included accelerated depreciation of leasehold improvements in the amount of $1.2 million associated with the North Carolina facility, $0.2 million related to a change in the accrued lease costs pertaining to the estimated future obligations for non-cancelable lease payments for our San Jose, California facility and the reversal of $0.2 million of estimated severance benefits. This charge is reflected in “Restructuring charge, net of reversals” in the condensed consolidated statements of operations. The excess facilities payments will continue through fiscal year 2023, due to the length of the lease agreements.

Commitments And Contingencies Disclosure [Abstract]

Commitments and Contingencies

8.	Commitments and Contingencies

Purchase Commitments

The Company currently has arrangements with contract manufacturers and suppliers for the manufacture of its products. The arrangements allow them to procure long lead-time component inventory based upon a rolling production forecast provided by the Company. The Company is obligated to purchase long lead-time component inventory that its contract manufacturer procures in accordance with the Company’s forecast, unless the Company gives notice of order cancellation outside of applicable component lead-times. As of March 31, 2016, the Company had non-cancelable commitments to purchase $$68.5 million of such inventory.

Legal Proceedings

The Company may from time to time be party to litigation arising in the course of its business, including, without limitation, allegations relating to commercial transactions, business relationships or intellectual property rights. Such claims, even if not meritorious, could result in the expenditure of significant financial and managerial resources. Litigation in general and intellectual property and securities litigation in particular, can be expensive and disruptive to normal business operations. Moreover, the results of legal proceedings are difficult to predict.

In accordance with applicable accounting guidance, the Company records accruals for certain of its outstanding legal proceedings, investigations or claims when it is probable that a liability will be incurred and the amount of loss can be reasonably estimated. The Company evaluates, at least on a quarterly basis, developments in legal proceedings, investigations or claims that could affect the amount of any accrual, as well as any developments that would result in a loss contingency to become both probable and reasonably estimable. When a loss contingency is not both probable and reasonably estimable, the Company does not record a loss accrual. However, if the loss (or an additional loss in excess of any prior accrual) is at least a reasonable possibility and material, then the Company would disclose an estimate of the possible loss or range of loss, if such estimate can be made, or disclose that an estimate cannot be made. The assessment whether a loss is probable or a reasonable possibility, and whether the loss or a range of loss is estimable, involves a series of complex judgments about future events. Even if a loss is reasonably possible, the Company may not be able to estimate a range of possible loss, particularly where (i) the damages sought are substantial or indeterminate, (ii) the proceedings are in the early stages, or (iii) the matters involve novel or unsettled legal theories or a large number of parties. In such cases, there is considerable uncertainty regarding the ultimate resolution of such matters, including the amount of any possible loss, fine or penalty. Accordingly, for the proceedings listed below, except as noted below, the Company is currently unable to estimate any reasonably possible loss or range of possible loss. Based on its own investigations, the Company believes the ultimate outcome of any current legal proceedings, individually and in the aggregate, will not have a material adverse effect on its financial position, results of operation or cash flows. However, because of the nature and inherent uncertainties of the litigation, should the outcome of such actions be unfavorable, the Company's business, financial condition, results of operations or cash flows could be materially and adversely affected.

Brazilian Tax Assessment Matters

Certain Brazilian tax authorities have made tax assessments against our Brazilian subsidiary, Enterasys Networks do Brazil Ltda., based on an alleged underpayment of taxes. The tax authorities are also seeking interest and penalties with respect to such claims (collectively, the “ICMS Tax Assessments”). The State of Sao Paolo, Brazil denied Enterasys Networks do Brazil Ltda. the use of certain tax credits granted by the State of Espirito Santo, Brazil under the terms of the FUNDAP program for the tax years of 2002 through 2009. The Company’s application to resolve the ICMS Tax Assessments at the administrative level of the Sao Paolo Tax Department under the amnesty relief program (Reference No 3.056.963-1) was denied in March, 2014, by the Sao Paolo Tax Administration. The value of the ICMS tax credits that were disallowed by the Sao Paolo Tax Administration is BR 3.4 million (US $0.9 million), plus interest and penalties BR 16.6 million (US $4.6 million). Possible court fees are estimated to be BR 4.0 million (US $1.1 million). On January 10, 2014, the Company filed a lawsuit to overturn or reduce the ICMS Assessments, which lawsuit remains on-going. As part of this lawsuit, the Company made a request for a stay of execution, so that no tax foreclosure can be filed until a final ruling is made and no guarantee needs to be presented. On or about October 6, 2014, the preliminary injunction was granted with regard to the stay of execution, and in response to an appeal on the guarantee requirement, the appellant court further ruled on or about January 28, 2015 that no cash deposit (or guarantee) need be made by the Company.

On or about June 18, 2014, the State of San Paolo notified Enterasys Networks do Brazil Ltda. that it intends to audit the records of such entity for tax years 2012 and 2013. In addition, the Company received a similar notice in December 2015 with respect to an audit by the State of San Paolo of tax years 2011-2014. The audits are expected to cover the same or very similar issues as the ICMS Tax Assessments for tax years 2002-2009, however, the Company changed its ICMS procedures effective May 2009 and a similar tax assessment is not anticipated. The Company has provided the requested information for these tax years to the Brazilian tax authorities, but has received no further response from the Brazilian tax authorities.

Based on the currently available information, the Company believes the ultimate outcome of the above audits and assessments will not have a material adverse effect on the Company's financial position or overall results of operations. The Company believes that the ICMS Tax Assessments against our Brazilian subsidiary are without merit and the Company is defending the claims vigorously. While the Company believes there is no legal basis for the alleged liability, due to the complexities and uncertainty surrounding the judicial process in Brazil and the nature of the claims asserted, it is unable to determine the likelihood of an unfavorable outcome against our Brazilian subsidiary and estimate the potential tax liability related to the ICMS Tax Assessments, if any, may be up to BR 23.4 million (US $6.4 million). The Company does not expect a final judicial determination for several years. The Company believes BR 9.4 million (US $2.6 million) is the best estimate within the range and has recorded an accrual as of the Acquisition Date of Enterasys Networks as such matter relates to the period before the acquisition.

The Company made a demand on April 11, 2014 for a defense from, and indemnification by, the former equity holder of Enterasys Networks (“Seller”) of the ICMS Tax Assessments. Seller agreed to assume the defense of the ICMS Tax Assessments on May 20, 2014. In addition, through the settlement of the Unify Indemnification Suit on June 18, 2015, Seller has agreed to continue to defend the Company with respect to the ICMS Tax Assessments and to indemnify the Company for losses related thereto subject to certain conditions. In addition, the Seller has agreed to indemnify the Company in connection with tax assessments up to a specified cap related to the 2012 and 2013 tax years subject to certain conditions. These conditions include the offsetting of foreign income tax benefits realized by the Company in the connection with the acquisition of Enterasys. Based upon current projections of the foreign income tax benefits to be realized, the Company does not anticipate that any amounts under the indemnification will be due from the Seller in connection with either the ICMS Tax Assessments or any potential tax assessments for tax years 2012 and 2013.

In re Extreme Networks, Inc. Securities Litigation

On October 23 and 29, 2015, complaints were filed for violations of securities laws in the U.S. District Court for the Northern District of California against the Company and three of its current or former officers (Charles W. Berger, Kenneth B. Arola, and John T. Kurtzweil). Subsequently, the cases were consolidated. Plaintiffs allege that defendants violated the securities laws by disseminating materially false and misleading statements and concealing material adverse facts regarding Extreme Networks' current financial condition and growth prospects. Plaintiffs seek damages of an unspecified amount on behalf of a class of investors who purchased the Company's common stock from November 4, 2013 through April 9, 2015. Motions for appointment of lead plaintiff have been filed, and are scheduled to be heard on May 5, 2016. The Company believes the claims are without merit and intends to vigorously defend the claims.

On February 18, 2016, a shareholder derivative case was filed in the Superior Court of California, Santa Clara County. Shaffer v. Kispert et al., No. 16 CV 291726. The complaint names current and former officers and\ or members of the Board of Directors as defendants and seeks recovery on behalf of the Company based on substantially the same allegations as the securities class action litigation described above. The parties have agreed to stay the case pending further activities in the securities class action litigation, and have submitted a stipulation to that effect to the court.

Indemnification Obligations

Subject to certain limitations, the Company may be obligated to indemnify its current and former directors, officers and employees. These obligations arise under the terms of its certificate of incorporation, its bylaws, applicable contracts, and Delaware law. The obligation to indemnify, where applicable, generally means that the Company is required to pay or reimburse, and in certain circumstances the Company has paid or reimbursed, the individuals' reasonable legal expenses and possibly damages and other liabilities incurred in connection with these matters. It is not possible to estimate the maximum potential amount under these indemnification agreements due to the limited history of these claims. The cost to defend the Company and the named individuals could have a material adverse effect on its consolidated financial position, results of operations and cash flows in the future. Recovery of such costs under its director and officers’ insurance coverage is uncertain. As of March 31, 2016, the Company had no outstanding indemnification claims.

Income Tax Disclosure [Abstract]

Income Taxes

9.	Income Taxes

For the three and nine months ended March 31, 2016, the Company recorded an income tax provision of $0.9 million and $3.0 million, respectively. For the three and nine months ended March 31, 2015, the Company recorded an income tax provision of $1.1 million and $3.5 million, respectively.

The income tax provisions for the three and nine months ended March 31, 2016 and 2015, consisted primarily of taxes on the income of our foreign subsidiaries as well as tax expense associated with the establishment of a U.S. deferred tax liability for amortizable goodwill resulting from the acquisition of Enterasys Networks, Inc. The income tax provisions for both fiscal years were calculated based on the actual results of operations for the three and nine months ended March 31, 2016 and 2015, and therefore may not reflect the annual effective tax rate.

The Company has provided a full valuation allowance against all of its U.S. federal and state deferred tax assets as well as the deferred tax assets in Australia, Brazil, Japan and Singapore. A valuation allowance is determined by assessing both negative and positive evidence to determine whether it is “more likely than not” that the deferred tax assets are recoverable; such assessment is required on a jurisdiction by jurisdiction basis. The Company's inconsistent earnings in recent periods, including a cumulative loss over the last three years, coupled with its difficulty in forecasting future revenue trends as well as the cyclical nature of its business represent sufficient negative evidence to require a full valuation allowance against its U.S. federal and state net deferred tax assets as well as the above mentioned foreign jurisdictions. This valuation allowance will be evaluated periodically and can be reversed partially or in whole if business results and the economic environment have sufficiently improved to support realization of some or all of the Company's deferred tax assets.

During 2015, Congress passed legislation that would make the R&D Tax Credit permanent and on December 18, 2015, President Obama signed the Protecting Americans from Tax Hikes (“PATH”) Act of 2015, which includes a provision making permanent the R&D tax credit under Section 41 of the Code. This credit previously expired on December 31, 2014. The Company’s balance sheet at December 31, 2015, reflects this retroactive reinstatement of the credit to January 1, 2015 offset in full by a valuation allowance.

The acquisition of Enterasys included a U.S. parent company as well as its wholly-owned domestic and foreign subsidiaries. The Company has elected to treat this stock acquisition as an asset purchase by filing the required election forms under IRC Sec 338(h)(10). The Company has estimated the value of the intangible assets from this transaction and is amortizing the amount over 15 years for tax purposes. During the three and nine months ended March 31, 2016, the Company deducted $1.1 million and $3.4 million of tax amortization expense, respectively related to capitalized goodwill. As of March 31, 2016, the Company recorded a deferred tax liability of $3.6 million related to this amortization which is not considered a future source of taxable income in evaluating the need for a valuation allowance against our deferred tax assets.

The Company had $11.6 million of unrecognized tax benefits as of March 31, 2016. The future impact of the unrecognized tax benefit of $11.6 million, if recognized, would result in adjustments to deferred tax assets and corresponding adjustments to the valuation allowance. The Company does not anticipate any events to occur during the next twelve months that would reduce the unrealized tax benefit as currently stated in the Company’s balance sheet.

The Company’s policy is to accrue interest and penalties related to the underpayment of income taxes as a component of tax expense in the condensed consolidated statements of operations.

In general, the Company's U.S. federal income tax returns are subject to examination by tax authorities for fiscal years 2001 forward due to net operating losses and the Company's state income tax returns are subject to examination for fiscal years 2003 forward due to net operating losses.

Earnings Per Share [Abstract]

Net Loss Per Share

10.	Net Loss Per Share

Basic earnings per share is calculated by dividing net earnings by the weighted average number of common shares outstanding during the period. Dilutive earnings per share is calculated by dividing net earnings by the weighted average number of common shares used in the basic earnings per share calculation plus the dilutive effect of shares subject to repurchase, options, warrants and unvested restricted stock units.

The following table presents the calculation of basic and diluted net loss per share (in thousands, except per share data):

	Three Months Ended						Nine Months Ended
	March 31, 2016			March 31, 2015			March 31, 2016			March 31, 2015
Net loss	$	(10,784	)	$	(23,548	)	$	(29,544	)	$	(55,983	)
Weighted-average shares used in per share calculation - basic and diluted		104,104			99,783			102,486			98,591
Net loss per share - basic and diluted	$	(0.10	)	$	(0.24	)	$	(0.29	)	$	(0.57	)

The following securities were excluded from the computation of diluted net loss per share of common stock for the periods presented as their effect would have been anti-dilutive (in thousands):

	March 31, 2016		March 31, 2015
Options to purchase common stock		4,827		9,839

Foreign Exchange Forward Contracts

Derivative Instruments And Hedging Activities Disclosure [Abstract]

Foreign Exchange Forward Contracts

11.	Foreign Exchange Forward Contracts

The Company from time to time enters into foreign exchange forward contracts to mitigate the effect of gains and losses generated by the foreign currency forecasted transactions related to certain operating expenses and re-measurement of certain assets and liabilities denominated in foreign currencies. These derivatives do not qualify as hedges. Changes in the fair value of these foreign exchange forward contracts are offset largely by re-measurement of the underlying assets and liabilities. At March 31, 2016, we did not have any forward foreign currency contracts.

Foreign currency transaction gains and losses from operations was a loss of $0.3 million and gain of $1.1 million for the three and nine months ended March 31, 2016, respectively. Foreign currency transaction gains and losses from operations was a loss of $0.5 million and a loss of $0.9 million for the three and nine months ended March 31, 2015, respectively.

Summary of Significant Accounting Policies (Policies)	9 Months Ended
Summary of Significant Accounting Policies (Policies)	Mar. 31, 2016
Accounting Policies [Abstract]
Fiscal Year	Fiscal Year The Company uses a fiscal calendar year ending on June 30. All references herein to "fiscal 2016" or "2016" represent the fiscal year ending June 30, 2016.
Principles of Consolidation	Principles of Consolidation The consolidated financial statements include the accounts of Extreme Networks and its wholly-owned subsidiaries. All inter-company accounts and transactions have been eliminated.
Accounting Estimates	Accounting Estimates The preparation of financial statements and related disclosures in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Estimates are used for, but are not limited to, the accounting for the allowances for doubtful accounts and sales returns, determining the fair value of acquired assets and assumed liabilities, estimated selling prices, inventory valuation and purchase commitments, depreciation and amortization, impairment of long-lived assets including goodwill, warranty accruals, restructuring liabilities, measurement of share-based compensation costs and income taxes. Actual results could differ materially from these estimates. The Company predominantly uses the United States Dollar as its functional currency. The functional currency for certain of its foreign subsidiaries is the local currency. For those subsidiaries that operate in a local currency functional environment, all assets and liabilities are translated to United States Dollars at current month end rates of exchange; and revenue and expenses are translated using the monthly average rate.
Earnings Per Share	Dilutive earnings per share is calculated by dividing net earnings by the weighted average number of common shares used in the basic earnings per share calculation plus the dilutive effect of shares subject to repurchase, options, warrants and unvested restricted stock units.
Investments	The Company considers highly liquid investments with maturities of three months or less at the date of purchase to be cash equivalents. Investments with original maturities of greater than three months, but less than one year at the balance sheet date are classified as short-term investments.
Deferred Revenue	Deferred Revenue, Net Deferred revenue, net represents amounts for (i) deferred services revenue (support arrangements, professional services and training), and (ii) deferred product revenue net of the related cost of revenue when the revenue recognition criteria have not been met. The Company offers for sale to its customers, renewable support arrangements that range from one to five years. Deferred support revenue is included within deferred revenue, net within the services category above. Deferred Distributors Revenue, Net of Cost of Sales to Distributors The Company records revenue from its distributors on a sell-through basis, recording deferred revenue and deferred cost of sales associated with all sales transactions to its distributors in “Deferred distributors revenue, net of cost of sales to distributors” in the liability section of its condensed consolidated balance sheets. The amount shown as “Deferred distributors revenue, net of cost of sales to distributors” represents the deferred gross profit on sales to distributors based on contractual pricing.
Guarantees and Product Warranties	Guarantees and Product Warranties Networking products may contain undetected hardware or software errors when new products or new versions or updates of existing products are released to the marketplace. In the past, we had experienced such errors in connection with products and product updates. The Company’s standard hardware warranty period is typically 12 months from the date of shipment to end-users and 90 days for software. For certain access products, the Company offers a limited lifetime hardware warranty commencing on the date of shipment from the Company and ending five (5) years following the Company’s announcement of the end of sale of such product. Upon shipment of products to its customers, the Company estimates expenses for the cost to repair or replace products that may be returned under warranty and accrue a liability in cost of product revenue for this amount. The determination of the Company’s warranty requirements is based on actual historical experience with the product or product family, estimates of repair and replacement costs and any product warranty problems that are identified after shipment. The Company estimates and adjusts these accruals at each balance sheet date in accordance with changes in these factors. Upon issuance of a standard product warranty, the Company discloses and recognizes a liability for the obligations it assumes under the product warranty. To facilitate sales of its products in the normal course of business, the Company indemnifies its resellers and end-user customers with respect to certain matters. The Company has agreed to hold the customer harmless against losses arising from a breach of intellectual property infringement or other claims made against certain parties. These agreements may limit the time within which an indemnification claim can be made and the amount of the claim. It is not possible to estimate the maximum potential amount under these indemnification agreements due to the limited history of prior indemnification claims and the unique facts and circumstances involved in each particular agreement. Historically, payments made by the Company under these agreements have not had a material impact on its operating results or financial position.

- Definition

Cash includes currency on hand as well as demand deposits with banks or financial institutions. It also includes other kinds of accounts that have the general characteristics of demand deposits in that the customer may deposit additional funds at any time and effectively may withdraw funds at any time without prior notice or penalty. Cash equivalents, excluding items classified as marketable securities, include short-term, highly liquid Investments that are both readily convertible to known amounts of cash, and so near their maturity that they present minimal risk of changes in value because of changes in interest rates. Generally, only investments with original maturities of three months or less qualify under that definition. Original maturity means original maturity to the entity holding the investment. For example, both a three-month US Treasury bill and a three-year Treasury note purchased three months from maturity qualify as cash equivalents. However, a Treasury note purchased three years ago does not become a cash equivalent when its remaining maturity is three months. Short-term investments, exclusive of cash equivalents, generally consist of marketable securities intended to be sold within one year (or the normal operating cycle if longer) and may include trading securities, available-for-sale securities, or held-to-maturity securities (if maturing within one year), as applicable.
