Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES: As of September 30, 2017 and December 31, 2016, the Company had gross unrecognized tax benefits of $46.0 million and $41.5 million, respectively. It is the Company’s policy to classify accrued interest and penalties as part of the unrecognized tax benefits and record the expense in the provision for income taxes. The amount of accrued interest and penalties related to unrecognized tax benefits totaled $2.6 million at September 30, 2017 and $1.8 million at December 31, 2016. On January 12, 2017, the Company received a ruling from the Israeli Tax Authorities ("ITA"), which approved a succession of mergers in a tax-exempted manner, subject to certain limitations (the "Tax-Exempted Merger"), in which EZchip Technologies Ltd., fully owned by EZchip, merged into EZchip, which in turn merged into the Company. The Tax-Exempted Merger resulted in a net increase of approximately $0.9 million in deferred tax assets and a corresponding increase in benefit from taxes on income during the first quarter of 2017. As of September 30, 2017, the 2014 through 2016 tax years are open and may be subject to potential examinations in the United States. The Company has net operating losses in the United States from prior tax periods beginning in 2002 which may be subject to examination upon utilization in future tax periods. As of September 30, 2017, the 2011 through 2016 tax years are open and may be subject to potential examinations in Denmark and Israel. As of September 30, 2017, the income tax returns of the Company and one of its subsidiaries in Israel are under examination by the ITA for certain years from 2011 to 2014. The Company's operations in Israel were granted "Approved Enterprise" status by the Investment Center in the Israeli Ministry of Economy and "Beneficiary Enterprise" status from the Israeli Income Tax Authority, which makes the Company eligible for tax benefits under the Israeli Law for Encouragement of Capital Investments, 1959 (the "Encouragement Law"). Under the terms of the Beneficiary Enterprise program, income that is attributable to the Company's operations in Yokneam, Israel, is exempt from income tax commencing fiscal year 2011 through 2021. Income that is attributable to the Company's operations in Tel Aviv, Israel is subject to a reduced income tax rate (generally between 10.0% and the current corporate tax rate, depending on the percentage of foreign investment in the Company) commencing fiscal year 2013 through 2021. On June 14, 2017, the Israeli government legislated new regulations regarding the "Preferred Technological Enterprise" regime, under which a company that complies with the terms may be entitled to certain tax benefits. The Company expects that its operation in Israel will comply with the terms of the Preferred Technological Enterprise regime. Therefore, the Company may utilize the tax benefits under this regime after the end of the benefit period of its Approved and Beneficiary Enterprise statuses (i.e. from fiscal year 2022 onwards). Under the new legislation, the majority of the Company’s income from its operations in Yokneam, Israel, will be subject to a corporate rate of 7.5%, while the majority of the income from its operations in Tel-Aviv, Israel, will be subject to a corporate rate of 12.0%. As a result of the lower tax rates mentioned above, the Company recorded a decrease of approximately $0.2 million in deferred tax assets and a corresponding increase in tax expense during the second quarter of 2017. The Company’s effective tax rate is highly dependent upon the geographic distribution of its worldwide earnings or losses, tax regulations and tax holiday benefits in Israel, and the effectiveness of the Company’s tax planning strategies. The Company’s effective tax rates were 38.4% and 6.8% for the three months ended September 30, 2017 and 2016, respectively. The Company’s effective tax rates were (20.9)% and 25.6% for the nine months ended September 30, 2017 and 2016, respectively. The difference between the Company’s effective tax rate and the 35.0% federal statutory rate for the nine months ended September 30, 2017 resulted primarily from the tax holiday in Israel and foreign earnings taxed at rates lower than the federal statutory rates, partially offset by the accrual of unrecognized tax benefits, interest and penalties associated with unrecognized tax positions, non-tax-deductible expenses such as share-based compensation and losses generated from subsidiaries without tax benefit. The application of income tax law is inherently complex. Laws and regulations in this area are voluminous and are often ambiguous, and the Company is required to make many subjective assumptions and judgments regarding its income tax exposures. In addition, interpretations of and guidance surrounding income tax laws and regulations are subject to change over time. Any changes in the Company’s subjective assumptions and judgments could materially affect amounts recognized in its condensed consolidated balance sheets and statements of operations. The Company has maintained a valuation allowance against deferred tax assets of certain subsidiaries. The Company assesses its ability to recover its deferred tax assets on an ongoing basis. Significant management judgment is required in determining any valuation allowance recorded against deferred tax assets. In evaluating the ability to recover deferred tax assets, the Company considers available positive and negative evidence including its recent cumulative losses, its ability to carry-back losses against prior taxable income and its projected financial results. The Company also considers, commensurate with its objective verifiability, the forecast of future taxable income including the reversal of temporary differences and the implementation of feasible and prudent tax planning strategies. A valuation allowance may be recorded in the event it is deemed to be more-likely-than-not that the deferred tax asset cannot be realized. Previously established valuation allowances may also be released in the event it is deemed to be more-likely-than-not that the deferred tax asset can be realized. Any release of valuation allowance will be recorded as a tax benefit which will positively impact the Company’s operating results. Management has determined on the basis of the quarterly assessment performed at September 30, 2017, that these deferred tax assets are not more-likely-than-not to be realized.
