Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company recorded an income tax provision of $1.1 million and $3.5 million, for the three and nine months ended March 31, 2015, respectively. The Company recorded an income tax provision of $0.9 million and $2.3 million for the three and nine months ended March 31, 2014, respectively. The income tax provisions for the three and nine months ended March 31, 2015 and 2014, 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, 2015 and 2014, 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 substantially all of the acquired Enterasys foreign entities’ deferred tax assets. No valuation allowance has been established against the non-U.S. deferred tax assets of the legacy Extreme Networks, Inc. foreign subsidiaries. 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, coupled with the Company's inability to forecast greater than one quarter in advance and 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. 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. The Company deducted $1.1 million and $3.4 million, during the three and nine months ended March 31, 2015, respectively of tax amortization expense related to capitalized goodwill. The Company recorded a deferred tax liability of $2.4 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 as of March 31, 2015. The Company had $11.3 million of unrecognized tax benefits as of March 31, 2015. The future impact of the unrecognized tax benefit of $11.3 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. Estimated interest and penalties related to the underpayment of income taxes are classified as a component of tax expense in the Condensed Consolidated Statements of Operations and were immaterial for the three and nine months ended March 31, 2015 and 2014. Accrued interest and penalties were $42,000 as of March 31, 2014, and have been fully reversed as of March 31, 2015. 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.
