Income Taxes	3 Months Ended
Mar. 31, 2018
Income Tax Disclosure [Abstract]
Income Taxes	(13) Income Taxes During the three months ended March 31, 2018, Juniper recorded no income tax expense as the Company had net loss carryforwards to off-set expected taxable income forecasted for the year which are fully offset by valuation allowances maintained in the U.S., United Kingdom and France. During the three months ended March 31, 2017, Juniper recorded no income tax expense due to expected losses forecasted for the year. On December 22, 2017 President Donald Trump signed into U.S. law the Tax Cuts and Jobs Act of 2017 (“Tax Reform”). ASC Topic 740, Accounting for Income Taxes, requires companies to recognize the effect of tax law changes in the period of enactment even though the effective date for most provisions is for tax years beginning after December 31, 2017, or in the case of certain other provisions of the law, January 1, 2018. One of the Tax Reform provisions effective January 1, 2018 includes a minimum tax on certain foreign earnings in excess of 10% of the foreign subsidiaries tangible assets (i.e., global intangible low-taxed income or “GILTI”). Under the U.S. generally accepted accounting principles, companies are allowed to make an accounting policy election of either (i) account for GILTI as a component of tax expense in the period in which the Company is subject to the rules (the “period cost method”), or (ii) account for GILTI in the Company’s measurement of deferred taxes (the “deferred method”). The Company is currently accounting for GILTI using the period cost method as it continues to evaluate the two policies available. Under the period cost method, the Company has included approximately $0.5 million GILTI in US taxable income, fully off-set by net operating loss carryforwards. Given the significance of the legislation, the FASB issued ASU No. 2018-05, Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118, which allows registrants to record provisional amounts during a one year “measurement period” similar to that used when accounting for business combinations. However, the measurement period is deemed to have ended prior to the one-year term when the registrant has obtained, prepared, and analyzed the information necessary to finalize its accounting. During the measurement period, impacts of the law are expected to be recorded at the time a reasonable estimate for all or a portion of the effects can be made, and provisional amounts can be recognized and adjusted as information becomes available, prepared, or analyzed. As of March 31, 2018, the Company has not recorded any incremental accounting adjustments related to the impact of Tax Reform that were recorded in its December 31, 2017 financial statements and it continues to assess its provisional estimate and technical interpretations of its application. The Company operates in multiple countries. Accordingly, separate tax filings are required based on jurisdiction. Due to the separate tax filings of our U.S., U.K. and France jurisdictions, the Company has evaluated the need for a valuation allowance on a separate jurisdiction basis. As of March 31, 2018, the Company continues to maintain a full valuation allowance against all net deferred tax assets. Tax Reform included a mandatory one-time tax on accumulated earnings of foreign subsidiaries, and as a result, all previously unremitted earnings for which no U.S. deferred tax liability had been accrued have now been subject to U.S. tax. Notwithstanding the U.S. taxation of these amounts, the Company intends to continue to invest all of these earnings, as well as the capital in these subsidiaries, indefinitely outside of the U.S. The amount of any unrecognized deferred tax liability on these undistributed earnings would be immaterial. The Company files tax returns in the United States, United Kingdom, France and various state jurisdictions. All of the Company’s tax years remain open to examination by major taxing jurisdictions to which the Company is subject, as carryforward attributes generated in past years may still be adjusted upon examination by the Internal Revenue Service or state and foreign tax authorities if they have or will be used in future periods. The Internal Revenue Service has concluded their audit of the 2011 and 2012 tax years. There were no material findings resulting from their audit. Additionally, with few exceptions, Juniper is no longer subject to U.S. state tax examinations for years prior to 2012.
