10.	Income Taxes

For the three months ended December 31, 2016 and 2015, the Company recorded an income tax provision of $1.2 million and $1.2 million, respectively. For the six months ended December 31, 2016 and 2015, the Company recorded an income tax provision of $2.1 million and $2.1 million, respectively.

The income tax provisions for the three months ended December 31, 2016 and 2015, consisted primarily of taxes on the income of the Company’s 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. and the WLAN Business of Zebra. The income tax provisions for both fiscal years were calculated based on the actual results of operations for the three months ended December 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 and Japan. 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.

The acquisition of Enterasys included a U.S. parent company as well as its wholly-owned domestic and foreign subsidiaries. The Company 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 months ended December 31, 2016 and 2015, the Company deducted $1.1 million of tax amortization expense for each period related to capitalized goodwill. As of December 31, 2016, the Company recorded a deferred tax liability of $5.3 million related to this amortization which is not considered a future source of taxable income in evaluating the need for a valuation allowance against its deferred tax assets.

The Company had $19.0 million of unrecognized tax benefits as of December 31, 2016. The future impact of the unrecognized tax benefit of $18.9 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 2000 forward due to net operating losses.
