[1] A history of operating losses in recent years has led to uncertainty with respect to the Company’s ability to realize certain net deferred tax assets, and as a result, the Company recorded increased valuation allowances of $24.5 million, $4.2 million and $0.3 million, in the second, third and fourth quarters of fiscal 2014, respectively, against its U.S. net deferred tax assets. In 2015, the Company continued to record a valuation allowance against all of its U.S. net deferred tax assets, resulting in an increase in valuation allowance of $3.1 million in the fourth quarter of fiscal 2015. This increase in valuation allowance is offset partially by the release of $0.9 million valuation allowance against one of its Israel subsidiaries due to cumulative income generated in recent years.

[2] In the third quarter of fiscal 2015 and 2014, the Company recorded tax benefits of $0.5 million and $9.0 million, respectively, resulting from the expiration of the applicable statute of limitations relating to the tax audits in the U.S. for the years of 2011 and 2010, respectively.

[3] In the first quarter of fiscal 2015, the Company recorded an impairment charge of $2.5 million for its investment in VJU iTV Development GmbH as a result of its assessment that this investment was impaired on an other-than-temporary basis (See Note 5, “Investments in Other Equity Securities,” of the notes to our Consolidated Financial Statements for additional information).
