Accounting Policies [Abstract]
Basis of Presentation and Significant Accounting Policies [Text Block]	Basis of Presentation and Summary of Significant Accounting Policies (a) Principles of Consolidation The accompanying consolidated financial statements include the accounts of j2 Global and its direct and indirect wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. Reorganization On June 10, 2014, j2 Global, Inc., a Delaware corporation, completed a corporate reorganization (the “Holding Company Reorganization”) pursuant to which j2 Global, Inc. (the “Predecessor”), merged with j2 Merger Sub, Inc., a Delaware corporation and an indirect, wholly owned subsidiary of the Predecessor, and changed its name to “j2 Cloud Services, Inc.” The Predecessor surviving the merger became a direct, wholly owned subsidiary of a new public holding company, j2 Global Holdings, Inc. (the “Holding Company”), which in connection with the merger changed its name to j2 Global, Inc. At the effective time of the merger and in connection with the Holding Company Reorganization, all outstanding shares of common stock and preferred stock of the Predecessor were automatically converted into identical shares of common stock or preferred stock, as applicable, of the Holding Company on a one-for-one basis, and the Predecessor’s existing stockholders and other equity holders became stockholders and equity holders, as applicable, of the Holding Company in the same amounts and percentages as they were in the Predecessor prior to the Holding Company Reorganization. On August 10, 2016, j2 Cloud Services, Inc., a wholly owned subsidiary of the Company and a Delaware corporation, converted into a Delaware limited liability company which continues as j2 Cloud Services, LLC. On August 12, 2016, all of the equity interests in Ziff Davis, LLC, a Delaware limited liability company, and all of the equity interests in Advanced Messaging Technologies, Inc., a Delaware corporation, held by j2 Cloud Services, LLC, a Delaware limited liability company, were distributed to j2 Global, the parent company of j2 Cloud Services, LLC. (b) Use of Estimates The preparation of consolidated financial statements in accordance with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements, including judgments about investment classifications, and the reported amounts of net revenue and expenses during the reporting period. We believe that our most significant estimates are those related to valuation and impairment of marketable securities, valuation of assets acquired and liabilities assumed in connection with business combinations, long-lived and intangible asset impairment, contingent consideration, income taxes and contingencies and allowance for doubtful accounts. On an ongoing basis, management evaluates its estimates based on historical experience and on various other factors that the Company believes to be reasonable under the circumstances. Actual results could materially differ from those estimates. (c) Allowances for Doubtful Accounts j2 Global reserves for receivables it may not be able to collect. These reserves for the Company’s Business Cloud Services segment are typically driven by the volume of credit card declines and past due invoices and are based on historical experience as well as an evaluation of current market conditions. These reserves for the Company’s Digital Media segment are typically driven by past due invoices based on historical experience. On an ongoing basis, management evaluates the adequacy of these reserves. (d) Revenue Recognition Business Cloud Services The Company’s Business Cloud Services revenues substantially consist of monthly recurring subscription and usage-based fees, which are primarily paid in advance by credit card. In accordance with GAAP, the Company recognizes revenue when persuasive evidence of an arrangement exists, services have been provided, the sales price is fixed and determinable and collection is probable. The Company defers the portions of monthly, quarterly, semi-annually and annually recurring subscription and usage-based fees collected in advance and recognizes them in the period earned. Additionally, the Company defers and recognizes subscriber activation fees and related direct incremental costs over a subscriber’s estimated useful life. Along with our numerous proprietary Business Cloud Services solutions, the Company also generates revenues by reselling various third party solutions, primarily through our email security and online backup lines of business. These third party solutions, along with our proprietary products, allow the Company to offer customers a variety of solutions to better meet their needs. The Company determines whether reseller revenue should be reported on a gross or net basis by assessing whether the Company is acting as the principal or an agent in the transaction. If the Company is acting as the principal in a transaction, the Company reports revenue on a gross basis. If the Company is acting as an agent in a transaction, the Company reports revenue on a net basis. In determining whether the Company acts as the principal or an agent, the Company follows the accounting guidance for principal-agent considerations and the Company places the most weight on three factors: whether or not the Company (i) is the primary obligor in the arrangement, (ii) has latitude in determining pricing and (iii) bears credit risk. The Company records revenue on a gross basis with respect to reseller revenue as the Company is the primary obligator in the arrangement, has latitude in determining pricing and bears all credit risk associated with our reseller program partners. j2 Global’s Business Cloud Services also include patent license revenues generated under license agreements that provide for the payment of contractually determined fully paid-up or royalty-bearing license fees to j2 Global in exchange for the grant of non-exclusive, retroactive and future licenses to our intellectual property, including patented technology. Patent revenues may also consist of revenues generated from the sale of patents. Patent license revenues are recognized when earned over the term of the license agreements. With regard to fully paid-up license arrangements, the Company recognizes as revenue in the period the license agreement is executed the portion of the payment attributable to past use of the intellectual property and amortizes the remaining portion of such payments on a straight-line basis, or pro-rata revenue basis, as appropriate over the life of the licensed patent(s). With regard to royalty-bearing license arrangements, the Company recognizes revenues of license fees earned during the applicable period. With regard to patent sales, the Company recognizes as revenue in the period of the sale the amount of the purchase price over the carrying value of the patent(s) sold. The Business Cloud Services business also generates revenues by licensing certain technology to third parties. These licensing revenues are recognized when earned in accordance with the terms of the underlying agreement. Generally, revenue is recognized as the third party uses the licensed technology over the period. Digital Media The Company’s Digital Media revenues primarily consist of revenues generated from the sale of advertising campaigns that are targeted to the Company’s proprietary websites and to those websites operated by third parties that are part of the Digital Media business’s advertising network. Revenues for these advertising campaigns are recognized as earned, either when an ad is placed for viewing by a visitor to the appropriate web page or when the visitor “clicks through” on the ad, depending upon the terms with the individual advertiser. Revenues for Digital Media business-to-business operations consist of lead-generation campaigns for IT vendors and are recognized as earned when the Company delivers the qualified leads to the customer. j2 Global also generates Digital Media revenues through the license of certain assets to clients, for the clients’ use in their own promotional materials or otherwise. Such assets may include logos, editorial reviews, or other copyrighted material. Revenues under such license agreements are recognized when the assets are delivered to the client. Also, Digital Media revenues are generated through the license of certain speed testing technology which is recognized when delivered to the client through providing data services primarily to Internet Service Providers (“ISPs”) and wireless carriers which is recognized as earned over the term of the access period. The Digital Media business also generates other types of revenues, including business listing fees, subscriptions to online publications, and from other sources. Such other revenues are recognized as earned. The Company determines whether Digital Media revenue should be reported on a gross or net basis by assessing whether the Company is acting as the principal or an agent in the transaction. If the Company is acting as the principal in a transaction, the Company reports revenue on a gross basis. If the Company is acting as an agent in a transaction, the Company reports revenue on a net basis. In determining whether the Company acts as the principal or an agent, the Company follows the accounting guidance for principal-agent considerations and the Company places the most weight on three factors: whether or not the Company (i) is the primary obligor in the arrangement, (ii) has latitude in determining pricing and (iii) bears credit risk. The Company records revenue on a gross basis with respect to revenue generated (i) by the Company serving online display and video advertising across its owned-and-operated web properties, on third party sites or on unaffiliated advertising networks, (ii) through the Company’s lead-generation business and (iii) through the Company’s Digital Media licensing program. The Company records revenue on a net basis with respect to revenue paid to the Company by certain third-party advertising networks who serve online display and video advertising across the Company’s owned-and-operated web properties and certain third party sites. (e) Fair Value Measurements j2 Global complies with the provisions of Financial Accounting Standards Board (“FASB”) Accounting Standard Codification (“ASC”) Topic No. 820, Fair Value Measurements and Disclosures (“ASC 820”), in measuring fair value and in disclosing fair value measurements. ASC 820 provides a framework for measuring fair value and expands the disclosures required for fair value measurements of financial and non-financial assets and liabilities. As of December 31, 2016 , the carrying value of cash and cash equivalents, short-term investments, accounts receivable, interest receivable, accounts payable, accrued expenses, interest payable, customer deposits and long-term debt are reflected in the financial statements at cost. With the exception of long-term debt, cost approximates fair value due to the short-term nature of such instruments. The fair value of the Company’s outstanding debt was determined using the quoted market prices of debt instruments with similar terms and maturities, if available. As of the same dates, the carrying value of other long-term liabilities approximated fair value as the related interest rates approximate rates currently available to j2 Global. (f) Cash and Cash Equivalents j2 Global considers cash equivalents to be only those investments that are highly liquid, readily convertible to cash and with maturities of three months or less at the purchase date. (g) Investments j2 Global accounts for its investments in debt and equity securities in accordance with FASB ASC Topic No. 320, Investments - Debt and Equity Securities (“ASC 320”). Debt investments are typically comprised of corporate and governmental debt securities. Equity securities recorded as available-for-sale represent strategic equity investments. j2 Global determines the appropriate classification of its investments at the time of acquisition and evaluates such determination at each balance sheet date. Held-to-maturity securities are those investments which the Company has the ability and intent to hold until maturity and are recorded at amortized cost. Available-for-sale securities are those investments j2 Global does not intend to hold to maturity and can be sold. Available-for-sale securities are carried at fair value with unrealized gains and losses included in other comprehensive income. Trading securities are carried at fair value, with unrealized gains and losses included in investment income. Securities are accounted for on a specific identification basis, average cost method or other method, as appropriate. (h) Debt Issuance Costs and Debt Discount j2 Global capitalizes costs incurred with borrowing and issuance of debt securities and records debt issuance costs and discounts as a reduction to the debt amount. These costs and discounts are amortized and included in interest expense over the life of the borrowing or term of the credit facility using the effective interest method. (i) Derivative Instruments j2 Global currently holds an embedded derivative instrument related to contingent interest in connection with its 3.25% Convertible Notes issued on June 10, 2014. This embedded derivative instrument is carried at fair value with changes recorded to interest expense (see Note 5 - Fair Value Measurements). (j) Concentration of Credit Risk All of the Company’s cash, cash equivalents and marketable securities are invested at major financial institutions primarily within the United States, United Kingdom and Ireland. These institutions are required to invest the Company’s cash in accordance with the Company’s investment policy with the principal objectives being preservation of capital, fulfillment of liquidity needs and above market returns commensurate with preservation of capital. The Company’s investment policy also requires that investments in marketable securities be in only highly rated instruments, with limitations on investing in securities of any single issuer. However, these investments are not insured against the possibility of a total or near complete loss of earnings or principal and are inherently subject to the credit risk related to the continued credit worthiness of the underlying issuer and general credit market risks. At December 31, 2016 , the Company’s cash and cash equivalents were maintained in accounts that are insured up to the limit determined by the applicable governmental agency. The Company’s deposits held in qualifying financial institutions in Ireland are fully insured through March 28, 2018 to the extent on deposit prior to March 28, 2013. With respect to the Company’s deposits with financial institutions in other jurisdictions, the insured amount held in other institutions is immaterial in comparison to the total amount of the Company’s cash and cash equivalents held by these institutions which is not insured. These institutions are primarily in the United States and United Kingdom, however, the Company has accounts within several other countries including Australia, Austria, China, France, Germany, Italy, Japan, New Zealand and the Netherlands. (k) Foreign Currency Some of j2 Global’s foreign subsidiaries use the local currency of their respective countries as their functional currency. Assets and liabilities are translated at exchange rates prevailing at the balance sheet dates. Revenues, costs and expenses are translated into U.S. Dollars at average exchange rates for the period. Gains and losses resulting from translation are recorded as a component of accumulated other comprehensive income (loss). Net translation gain/(loss) was $(23.1) million , $(15.1) million and $(14.7) million for the years ended December 31, 2016 , 2015 and 2014 , respectively. Realized gains and losses from foreign currency transactions are recognized within other expense (income), net. Net transaction gain/(loss) was $(0.7) million , $(0.1) million and $(0.1) million for the years ended December 31, 2016, 2015 and 2014, respectively. (l) Property and Equipment Property and equipment are stated at cost. Equipment under capital leases is stated at the present value of the minimum lease payments. Depreciation is calculated using the straight-line method over the estimated useful lives of the assets. The estimated useful lives of property and equipment range from 1 to 10 years. Fixtures, which are comprised primarily of leasehold improvements and equipment under capital leases, are amortized on a straight-line basis over their estimated useful lives or for leasehold improvements, the related lease term, if less. The Company has capitalized certain internal use software and website development costs which are included in property and equipment. The estimated useful life of costs capitalized is evaluated for each specific project and ranges from 1 to 5 years. (m) Long-Lived Assets j2 Global accounts for long-lived assets, which include property and equipment and identifiable intangible assets with finite useful lives (subject to amortization), in accordance with the provisions of FASB ASC Topic No. 360, Property, Plant, and Equipment (“ASC 360”), which requires that long-lived assets be reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability is measured by comparing the carrying amount of an asset to the expected undiscounted future net cash flows generated by the asset. If it is determined that the asset may not be recoverable, and if the carrying amount of an asset exceeds its estimated fair value, an impairment charge is recognized to the extent of the difference. j2 Global assessed whether events or changes in circumstances have occurred that potentially indicate the carrying amount of long-lived assets may not be recoverable. No impairment was recorded in fiscal year 2016, 2015 or 2014. (n) Goodwill and Intangible Assets Goodwill represents the excess of the purchase price over the fair value of the net tangible and identifiable intangible assets acquired in a business combination. Intangible assets resulting from the acquisitions of entities accounted for using the purchase method of accounting are recorded at the estimated fair value of the assets acquired. Identifiable intangible assets are comprised of purchased customer relationships, trademarks and trade names, developed technologies and other intangible assets. Intangible assets subject to amortization are amortized over the period of estimated economic benefit ranging from 1 to 20 years. In accordance with FASB ASC Topic No. 350, Intangibles - Goodwill and Other (“ASC 350”), goodwill and other intangible assets with indefinite lives are not amortized but tested annually for impairment or more frequently if j2 Global believes indicators of impairment exist. In connection with the annual impairment test for goodwill, the Company has the option to perform a qualitative assessment in determining whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If the Company determines that it was more likely than not that the fair value of the reporting unit is less than its carrying amount, then it performs the impairment test upon goodwill. The impairment test involves a two-step process. The first step involves comparing the fair values of the applicable reporting units with their aggregate carrying values, including goodwill. The Company generally determines the fair value of its reporting units using the income approach methodology of valuation. If the carrying value of a reporting unit exceeds the reporting unit’s fair value, j2 Global performs the second step of the test to determine the amount of impairment loss. The second step involves measuring the impairment by comparing the implied fair values of the affected reporting unit’s goodwill and intangible assets with the respective carrying values. In connection with the annual impairment test for indefinite-lived intangible assets, we have the option to perform a qualitative assessment in determining whether it is more likely than not that the fair value is less than its carrying amount, then we perform the impairment test upon indefinite-lived intangible assets. The impairment testing for indefinite-lived intangible assets consists of comparing the carrying values to the fair values and an impairment loss is recorded if the carrying value exceeds the fair value. j2 Global completed the required impairment review at the end of 2016, 2015 and 2014 and concluded that there were no impairments. Consequently, no impairment charges were recorded. (o) Contingent Consideration j2 Global measures the contingent earn-out liabilities in connection with acquisitions at fair value on a recurring basis using significant unobservable inputs classified within Level 3 of the fair value hierarchy (see Note 5 - Fair Value Measurements). The Company may use various valuation techniques depending on the terms and conditions of the contingent consideration including a Monte-Carlo simulation. This simulation uses a probability distribution for each significant input to produce hundreds or thousands of possible outcomes and the results are analyzed to determine probabilities of different outcomes occurring. Significant increases or decreases to these inputs in isolation would result in a significantly higher or lower liability with a higher liability capped by the contractual maximum of the contingent earn-out obligation. Ultimately, the liability will be equivalent to the amount paid, and the difference between the fair value estimate and amount paid will be recorded in earnings. The amount paid that is less than or equal to the liability on the acquisition date is reflected as cash used in financing activities in our consolidated statements of cash flows. Any amount paid in excess of the liability on the acquisition date is reflected as cash used in operating activities. j2 Global reviews and re-assess the estimated fair value of contingent consideration on a quarterly basis, and the updated fair value could differ materially from the initial estimates. Changes in the estimated fair value of our contingent earn-out liabilities related to the time component of the present value calculation are reported in interest expense. Adjustments to the estimated fair value related to changes in all other unobservable inputs are reported in operating income. (p) Income Taxes j2 Global’s income is subject to taxation in both the U.S. and numerous foreign jurisdictions. Significant judgment is required in evaluating the Company’s tax positions and determining its provision for income taxes. During the ordinary course of business, there are many transactions and calculations for which the ultimate tax determination is uncertain. j2 Global establishes reserves for tax-related uncertainties based on estimates of whether, and the extent to which, additional taxes will be due. These reserves for tax contingencies are established when the Company believes that certain positions might be challenged despite the Company’s belief that its tax return positions are fully supportable. j2 Global adjusts these reserves in light of changing facts and circumstances, such as the outcome of a tax audit or lapse of a statute of limitations. The provision for income taxes includes the impact of reserve provisions and changes to reserves that are considered appropriate. j2 Global accounts for income taxes in accordance with FASB ASC Topic No. 740, Income Taxes (“ASC 740”), which requires that deferred tax assets and liabilities be recognized using enacted tax rates for the effect of temporary differences between the book and tax basis of recorded assets and liabilities. ASC 740 also requires that deferred tax assets be reduced by a valuation allowance if it is more likely than not that some or all of the net deferred tax assets will not be realized. The valuation allowance is reviewed quarterly based upon the facts and circumstances known at the time. In assessing this valuation allowance, j2 Global reviews historical and future expected operating results and other factors, including its recent cumulative earnings experience, expectations of future taxable income by taxing jurisdiction and the carryforward periods available for tax reporting purposes, to determine whether it is more likely than not that deferred tax assets are realizable. ASC 740 provides guidance on the minimum threshold that an uncertain income tax benefit is required to meet before it can be recognized in the financial statements and applies to all income tax positions taken by a company. ASC 740 contains a two-step approach to recognizing and measuring uncertain income tax positions. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon settlement. If it is not more likely than not that the benefit will be sustained on its technical merits, no benefit will be recorded. Uncertain income tax positions that relate only to timing of when an item is included on a tax return are considered to have met the recognition threshold. j2 Global recognized accrued interest and penalties related to uncertain income tax positions in income tax expense on its consolidated statement of income. (q) Share-Based Compensation j2 Global accounts for share-based awards in accordance with the provisions of FASB ASC Topic No. 718, Compensation - Stock Compensation (“ASC 718”). Accordingly, j2 Global measures share-based compensation expense at the grant date, based on the fair value of the award, and recognizes the expense over the employee’s requisite service period using the straight-line method. The measurement of share-based compensation expense is based on several criteria, including but not limited to the valuation model used and associated input factors, such as expected term of the award, stock price volatility, risk free interest rate, dividend rate and award cancellation rate. These inputs are subjective and are determined using management’s judgment. If differences arise between the assumptions used in determining share-based compensation expense and the actual factors, which become known over time, j2 Global may change the input factors used in determining future share-based compensation expense. Any such changes could materially impact the Company’s results of operations in the period in which the changes are made and in periods thereafter. The Company estimates the expected term based upon the historical exercise behavior of our employees. j2 Global accounts for option grants to non-employees in accordance with FASB ASC Topic No. 505, Equity, whereby the fair value of such options is determined using the Black-Scholes option pricing model at the earlier of the date at which the non-employee’s performance is complete or a performance commitment is reached. (r) Earnings Per Common Share EPS is calculated pursuant to the two-class method as defined in ASC Topic No. 260, Earnings per Share (“ASC 260”), which specifies that all outstanding unvested share-based payment awards that contain rights to nonforfeitable dividends or dividend equivalents are considered participating securities and should be included in the computation of EPS pursuant to the two-class method. Basic EPS is calculated by dividing net distributed and undistributed earnings allocated to common shareholders, excluding participating securities, by the weighted-average number of common shares outstanding. The Company’s participating securities consist of its unvested share-based payment awards that contain rights to nonforfeitable dividends or dividend equivalents. Diluted EPS includes the determinants of basic EPS and, in addition, reflects the impact of other potentially dilutive shares outstanding during the period. The dilutive effect of participating securities is calculated under the more dilutive of either the treasury method or the two-class method. (s) Research, Development and Engineering Research, development and engineering costs are expensed as incurred. Costs for software development incurred subsequent to establishing technological feasibility, in the form of a working model, are capitalized and amortized over their estimated useful lives. (t) Segment Reporting FASB ASC Topic No. 280, Segment Reporting (“ASC 280”), establishes standards for the way that public business enterprises report information about operating segments in their annual consolidated financial statements and requires that those enterprises report selected information about operating segments in interim financial reports. ASC 280 also establishes standards for related disclosures about products and services, geographic areas and major customers. The Company operates as two segments: (1) Business Cloud Services and (2) Digital Media. (u) Advertising Costs Advertising costs are expensed as incurred. Advertising costs for the years ended December 31, 2016, 2015 and 2014 was $96.8 million , $63.5 million and $60.5 million , respectively. (v) Sales Taxes The Company may collect sales taxes from certain customers which are remitted to governmental authorities as required and are excluded from revenues. (w) Recent Accounting Pronouncements In May 2014, the FASB Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers, as a new Topic, (ASC) Topic 606. The new revenue recognition standard provides a five-step analysis of transactions to determine when and how revenue is recognized. The core principle is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In August 2015, the FASB issued ASU No. 2015-14, Revenue from Contracts with Customers: Deferral of the Effective Date, which deferred the effective date of the new revenue standard for periods beginning after December 15, 2016 to December 15, 2017, with early adoption permitted but not earlier than the original effective date. This ASU must be applied retrospectively to each period presented or as a cumulative-effect adjustment as of the date of adoption. The Company is considering the alternatives of adoption of this ASU, has substantially completed a review of the likely impact to the existing portfolio of customer contracts entered into prior to adoption and will continue to evaluate the effect of adopting this guidance upon the Company’s results of operations, cash flows and financial position. Currently, the Company does not expect the adoption of this ASU to have a material impact on our financial statements except that there are significant additional reporting requirements under the new standard. In November 2014, the FASB issued ASU No. 2014-16, Derivatives and Hedging (Topic 815): Determining Whether the Host Contract in a Hybrid Financial Instrument Issued in the Form of a Share is More Akin to Debt or to Equity, which clarifies how current guidance should be interpreted in evaluating the economic characteristics and risks of a host contract in a hybrid financial instrument that is issued in the form of a share. Specifically, the amendments clarify that an entity should consider all relevant terms and features, including the embedded derivative feature being evaluated for bifurcation, in evaluating the nature of the host contract. The assessment of the substance of the relevant terms and features should incorporate a consideration of: (1) the characteristics of the terms and features themselves; (2) the circumstances under which the hybrid financial instrument was issued or acquired; and (3) the potential outcomes of the hybrid financial instrument, as well as the likelihood of those potential outcomes. The amendments in this ASU apply to all entities that are issuers of, or investors in, hybrid financial instruments that are issued in the form of a share. The amendments in this ASU are effective for annual rep

Business Acquisition

Business Acquisition	12 Months Ended

Business Combinations [Abstract]
Business Acquisition	Business Acquisitions The Company uses acquisitions as a strategy to grow its customer base by increasing its presence in new and existing markets, expand and diversify its service offerings, enhance its technology, acquire skilled personnel and enter into other jurisdictions. The Company completed the following acquisitions during the year ended December 31, 2016, paying the purchase price in cash for each transaction: (a) an asset purchase of VaultLogix, acquired on February 17, 2016, a Massachusetts-based provider of cloud data backup and storage for business clients; (b) a share purchase of the entire issued capital of Callstream Group Limited, acquired on March 3, 2016, a provider of cloud-based call management solutions to markets in the United Kingdom; (c) an asset purchase of Publicaster, acquired on April 1, 2016, a Maryland-based provider of email marketing services; (d) an asset purchase of SMTP, acquired on June 27, 2016, a Florida-based provider of cloud email services offering solutions ranging from sophisticated transactional email solutions to cost-effective Simple Mail Transfer Protocol (“SMTP”) relay services; (e) a share purchase of the entire issued capital of Integrated Global Concepts, Inc. (“IGC”), acquired on July 12, 2016, a Chicago-based provider of fax and voicemail services; (f) a share purchase of the entire issued capital of Front-safe A/S, acquired on July 15, 2016, a Denmark-based provider of cloud backup solutions; (g) an asset purchase of Fonebox Australia., acquired on October 18, 2016, an Australia-based provider of voice, call routing and virtual receptionist business; (h) a share purchase of all the outstanding shares of common stock of Everyday Health Inc. (“Everyday Health”), acquired on December 5, 2016, a New York-based provider of digital health and wellness solutions; and (i) other immaterial acquisitions of online data backup, email marketing, email security and digital media businesses. The consolidated statement of income since the date of each acquisition and balance sheet, as of December 31, 2016 , reflect the results of operations of all 2016 acquisitions. For the year ended December 31, 2016 , these acquisitions contributed $52.9 million to the Company’s revenues. Net income contributed by these acquisitions was not separately identifiable due to j2 Global’s integration activities and is impracticable to provide. Total consideration for these transactions was $596.1 million , net of cash acquired and assumed liabilities and subject to certain post-closing adjustments which may increase or decrease the final consideration paid. The following table summarizes the allocation of the purchase consideration for all 2016 acquisitions (in thousands): Assets and Liabilities (1) Valuation Accounts receivable $ 70,922 Other assets 11,730 Property and equipment 11,109 Trade names 5,866 Trademarks 70,300 Customer relationships 85,482 Other intangibles 91,264 Goodwill 333,190 Accounts payables and accrued expenses (62,188 ) Deferred revenue (6,904 ) Deferred tax liability (14,503 ) Capital lease (194 ) Total $ 596,074 (1) In connection with the purchase of IGC, the majority of the value was associated with the 935,231 shares of j2 Global common stock held by IGC. The value associated with these shares was recorded as a separate transaction from the fax business and has been excluded from the schedule above. During 2016, the purchase price accounting has been finalized for the following acquisitions: (i) LiveVault, (ii) Salesify, (iii) VaultLogix (iv) Callstream Group Limited, (v) Publicaster (vi) SMTP (vii) Integrated Global Concepts, Inc. (viii) Front-safe A/S and (ix) other immaterial fax, online data backup and digital media businesses. The initial accounting for all other 2016 acquisitions is incomplete and subject to change, which may be significant. j2 Global has recorded provisional amounts which may be based upon past acquisitions with similar attributes for certain intangible assets (including trade names, software and customer relationships), preliminary acquisition date working capital and related tax items. During the year ended December 31, 2016, the Company recorded adjustments to prior period acquisitions primarily due to the finalization of the purchase accounting in the Business Cloud Services segment which resulted in a net increase in goodwill in the amount of $0.8 million . In addition, the Company recorded adjustments to the initial working capital related to prior period acquisitions and updated the purchase accounting of Offers.com in the Digital Media segment, which resulted in a net decrease in goodwill in the amount of $(5.0) million with a corresponding increase in trade names, net and other purchased intangibles, net (see Note 7 - Goodwill and Intangible Assets). Such adjustments had an immaterial impact to amortization expense within the Consolidated Statement of Income for the year ended December 31, 2016. Goodwill represents the excess of the purchase price over the fair value of the net tangible and identifiable intangible assets acquired and represents intangible assets that do not qualify for separate recognition. Goodwill recognized associated with these acquisitions during the year ended December 31, 2016 is $333.2 million , of which $102.4 million is expected to be deductible for income tax purposes. IGC The Company acquired the entire issued capital of IGC on July 12, 2016 for a cash purchase price of approximately $6.3 million (excluding amounts allocated to the Company’s purchase of its common stock described below), net of cash acquired and assumed liabilities and is subject to certain post-closing adjustments which may increase or decrease the final consideration paid. At the date of acquisition, IGC held 935,231 of the Company’s common stock which the Company determined should be treated as a separate transaction from the acquired fax and voicemail businesses. In order to determine the amount of purchase consideration allocable to the fax and voicemail business and the Company’s common stock, the Company used a relative fair value approach and concluded that the amounts of consideration allocable to the fax and voicemail business and the Company’s common stock were $6.3 million and $51.5 million , respectively. See Note 11 - Stockholders’ Equity for further discussion regarding the Company’s common stock acquired in connection with the IGC business combination. Everyday Health On December 5, 2016, the Company acquired all the outstanding shares of common stock of Everyday Health, $0.01 par value per share, at a purchase consideration $493.7 million (net of cash acquired and assumed liabilities) or $10.50 per share in cash, and subject to certain post-closing adjustments which may increase or decrease the final consideration paid. Everyday Health is a leading provider of digital health and marketing and communication solutions. Everyday Health attracts a large and engaged audience of consumers and healthcare professionals to its premier health and wellness properties and utilizes its data and analytics expertise to deliver highly personalized content experiences and efficient and effective marketing and engagement solutions. Everyday Health enables consumers to manage their daily health and wellness needs, healthcare professionals to stay informed and make better decisions for their patients, and marketers, health payers and providers to communicate and engage with consumers and healthcare professionals to drive better health outcomes. Everyday Health’s content and solutions are delivered through multiple channels, including desktop, mobile web, mobile phone and tablet applications, as well as video and social media. The Company acquired Everyday Health to bring together two leading digital media companies with complimentary visions and platforms to engage and monetize audiences. The combined company will be well positioned to deliver compelling benefits to customers with content that connects, informs and empowers audiences. The Company’s Digital Media segment maintains leading positions in the technology, gaming and men's lifestyle verticals with strong and well-established brands. Everyday Health adds a new vertical and set of market-leading trusted health properties to the portfolio while diversifying the company’s audience mix. The consolidated statement of income, since the date of acquisition, and balance sheet, as of December 31, 2016 , reflect the results of operations Everyday Health. For the year ended December 31, 2016 , Everyday Health contributed $23.2 million to the Company’s revenues. Net income contributed by Everyday Health was not separately identifiable due to j2 Global’s integration activities and is impracticable to provide. The following table summarizes the allocation of the purchase consideration for the Everyday Health acquisition (in thousands): Assets and Liabilities Valuation Cash $ 15,918 Accounts receivable 67,968 Other assets 11,168 Property and equipment 6,494 Trademarks 70,300 Customer relationships 45,500 Other intangibles 88,267 Goodwill 263,988 Accounts payables and accrued expenses (59,091 ) Deferred revenue (5,297 ) Deferred tax liability (11,500 ) Total $ 493,715 The initial accounting for the Everyday Health acquisition is substantially complete but is subject to change, which may be significant. Actual amounts recorded upon the finalization of these items may differ materially from the information presented in this Annual Report on Form 10-K. Goodwill represents the excess of the purchase price over the fair value of the net tangible and identifiable intangible assets acquired and represents intangible assets that do not qualify for separate recognition. Goodwill recognized associated with the Everyday Health acquisition during the year ended December 31, 2016 is $264.0 million , of which $65.4 million is expected to be deductible for income tax purposes. Pro Forma Financial Information for Everyday Health Acquisition The following unaudited pro forma supplemental information is based on estimates and assumptions, which j2 Global believes are reasonable. However, this information is not necessarily indicative of the Company’s consolidated financial position or results of income in future periods or the results that actually would have been realized had j2 Global and Everyday Health been combined companies during the periods presented.

Investments	Investments Short-term investments consist generally of corporate and governmental debt securities and certificates of deposits which are stated at fair market value. Realized gains and losses of short- and long-term investments are recorded using the specific identification method, average cost method or other method, as appropriate. The following table summarizes j2 Global’s debt securities designated as available-for-sale, classified by the contractual maturity date of the security (in thousands): December 31, December 31, 2015 Due within 1 year $ — $ 56,940 Due within more than 1 year but less than 5 years — 78,248 Due within more than 5 years but less than 10 years — — Due 10 years or after — 315 Total $ — $ 135,503 The following table summarizes the Company’s investments (in thousands): December 31, December 31, 2015 Available-for-sale $ — $ 158,158 Certificates of deposit 60 60 Total $ 60 $ 158,218 During the third quarter of 2016, the Company sold its strategic investment in Carbonite resulting in recognized gains before tax of $7.6 million ( $2.9 million of income tax), which is reflected in the Condensed Consolidated Statements of Income. In connection with the acquisition of Everyday Health (see Note 3 - Business Acquisitions), j2 Global liquidated all of its remaining available-for-sale investments to facilitate this transaction. The following table summarizes the gross unrealized gains and losses and fair values for investments classified as available for sale as of December 31, 2016 and December 31, 2015 aggregated by major security type (in thousands): Amortized Cost Gross Unrealized Gains Gross Unrealized Losses Fair Value December 31, 2016 Corporate debt securities $ — $ — $ — $ — Debt securities issued by the U.S. Treasury and other U.S. government corporations and agencies — — — — Debt securities issued by states of the United States and political subdivisions of the states — — — — Equity securities — — — — Total $ — $ — $ — $ — December 31, 2015 Corporate debt securities $ 88,852 $ 110 $ (213 ) $ 88,749 Debt securities issued by the U.S. Treasury and other U.S. government corporations and agencies 40,715 — (63 ) 40,652 Debt securities issued by states of the United States and political subdivisions of the states 6,111 2 (10 ) 6,103 Equity securities 18,536 4,118 — 22,654 Total $ 154,214 $ 4,230 $ (286 ) $ 158,158 For the years ended December 31, 2016 , 2015 and 2014 , the Company recorded realized gains from the sale of investments of approximately $7.7 million , $0.5 million and $0.1 million , respectively. Recognition and Measurement of Other-Than-Temporary Impairment j2 Global regularly reviews and evaluates each investment that has an unrealized loss. An unrealized loss exists when the current fair value of an individual security is less than its amortized cost basis. Unrealized losses that are determined to be temporary in nature are recorded, net of tax, in accumulated other comprehensive income for available-for-sale securities. Regardless of the classification of the securities as available-for-sale or held-to-maturity, the Company has assessed each position for impairment. Factors considered in determining whether a loss is temporary include: • the length of time and the extent to which fair value has been below cost; • the severity of the impairment; • the cause of the impairment and the financial condition and near-term prospects of the issuer; • activity in the market of the issuer which may indicate adverse credit conditions; and • the Company’s ability and intent to hold the investment for a period of time sufficient to allow for any anticipated recovery. j2 Global’s review for impairment generally entails: • identification and evaluation of investments that have indications of possible impairment; • analysis of individual investments that have fair values less than amortized cost, including consideration of the length of time the investment has been in an unrealized loss position and the expected recovery period; • discussion of evidential matter, including an evaluation of factors or triggers that could cause individual investments to qualify as having an other-than-temporary impairment and those that would not support an other-than-temporary impairment; • documentation of the results of these analyses, as required under business policies; and • information provided by third-party valuation experts. For these securities, a critical component of the evaluation for other-than-temporary impairments is the identification of credit impairment, where management does not expect to receive cash flows sufficient to recover the entire amortized cost basis of the security. Credit impairment is assessed using a combination of a discounted cash flow model that estimates the cash flows on the underlying securities and a market comparables method, where the security is valued based upon indications from the secondary market of what discounts buyers demand when purchasing similar securities. The cash flow model incorporates actual cash flows from the securities through the current period and then projects the remaining cash flows using relevant interest rate curves over the remaining term. These cash flows are discounted using a number of assumptions, some of which include prevailing implied credit risk premiums, incremental credit spreads and illiquidity risk premiums, among others. Securities that have been identified as other-than-temporarily impaired are written down to their current fair value. For debt securities that are intended to be sold or that management believes it more-likely-than-not that will be required to sell prior to recovery, the full impairment is recognized immediately in earnings. For available-for-sale and held-to-maturity securities that management has no intent to sell and believes that it more-likely-than-not that it will not be required to sell prior to recovery, only the credit loss component of the impairment is recognized in earnings, while the rest of the fair value impairment is recognized in other comprehensive income. The credit loss component recognized in earnings is identified as the amount of principal cash flows not expected to be received over the remaining term of the security. The following tables present gross unrealized losses and fair values for those investments that were in an unrealized loss position as of December 31, 2016 and December 31, 2015 , aggregated by investment category and the length of time that individual securities have been in a continuous loss position (in thousands): As of December 31, 2016 Less than 12 Months 12 Months or Greater Total Fair Value Unrealized Loss Fair Value Unrealized Loss Fair Value Unrealized Loss Corporate debt securities $ — $ — $ — $ — $ — $ — Debt securities issued by the U.S. Treasury and other U.S. government corporations and agencies — — — — — — Debt securities issued by states of the United States and political subdivisions of the states — — — — — — Total $ — $ — $ — $ — $ — $ — As of December 31, 2015 Less than 12 Months 12 Months or Greater Total Fair Value Unrealized Loss Fair Value Unrealized Loss Fair Value Unrealized Loss Corporate debt securities $ 74,807 $ (212 ) $ 1,000 $ (1 ) $ 75,807 $ (213 ) Debt securities issued by the U.S. Treasury and other U.S. government corporations and agencies 38,004 (62 ) 649 (1 ) 38,653 (63 ) Debt securities issued by states of the United States and political subdivisions of the states 4,189 (10 ) — — 4,189 (10 ) Total $ 117,000 $ (284 ) $ 1,649 $ (2 ) $ 118,649 $ (286 ) During the years ended December 31, 2016 and December 31, 2015 , we did not recognize any other-than-temporary impairment losses.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements j2 Global complies with the provisions of ASC 820, which defines fair value, provides a framework for measuring fair value and expands the disclosures required for fair value measurements of financial and non-financial assets and liabilities. ASC 820 clarifies that fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that is determined based on assumptions that market participants would use in pricing an asset or a liability. As a basis for considering such assumptions, ASC 820 establishes a three-tier value hierarchy, which prioritizes the inputs used in the valuation methodologies in measuring fair value: § Level 1 – Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets. § Level 2 – Observable inputs other than quoted prices in active markets for identical assets and liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. § Level 3 – Unobservable inputs which are supported by little or no market activity. The fair value hierarchy also requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The Company’s money market funds and its marketable equity securities are classified within Level 1. The Company values these Level 1 investments using quoted market prices. The Company’s debt investments, time deposits, and commercial paper, all of which have counterparties with high credit ratings, are classified within Level 2. The Company values these Level 2 investments based on quoted market prices or model-driven valuations using significant inputs derived from or corroborated by observable market data. The fair value of the Convertible Notes (see Note 8 - Long-Term Debt) is determined using recent quoted market prices or dealer quotes for such securities, which are Level 1 inputs. The fair value of the Senior Notes (see Note 8 - Long-Term Debt) is determined using quoted market prices or dealer quotes for instruments with similar maturities and other terms and credit ratings, which are Level 2 inputs. The fair value of long-term debt was $792.2 million and $790.5 million , at December 31, 2016 and December 31, 2015 , respectively. In addition, the Convertible Notes contain terms that may require the Company to pay contingent interest on the Convertible Notes which is accounted for as a derivative with fair value adjustments being recorded to interest expense. This derivative is fair valued using a binomial lattice convertible bond pricing model using historical and implied market information, which are Level 2 inputs. The Company classifies its contingent consideration liability in connection with the acquisitions of Ookla and Salesify within Level 3 because factors used to develop the estimated fair value are unobservable inputs, such as volatility and market risks, and are not supported by market activity. The fair value of the contingent consideration liability was determined using option based approaches. This methodology was utilized because the distribution of payments is not symmetric and amounts are only payable upon certain earnings before interest, tax, depreciation and amortization (“EBITDA”) thresholds being reached. Such valuation approach included a Monte-Carlo simulation for the contingency since the financial metric driving the payments is path dependent. Significant increases or decreases in either of the inputs noted above in isolation would result in a significantly lower or higher fair value measurement. The following tables present the fair values of the Company’s financial assets or liabilities that are measured at fair value on a recurring basis (in thousands): December 31, 2016 Level 1 Level 2 Level 3 Fair Value Assets: Cash equivalents: Money market and other funds $ 7,737 $ — $ — $ 7,737 Time deposits — — — — Certificates of Deposit — 60 — 60 Equity securities — — — — Debt securities issued by the U.S. Treasury and other U.S. government corporations and agencies — — — — Debt securities issued by states of the United States and political subdivisions of the states — — — — Debt securities issued by foreign governments — — — — Corporate debt securities — — — — Total assets measured at fair value $ 7,737 $ 60 $ — $ 7,797 Liabilities: Contingent consideration $ — $ — $ 17,450 $ 17,450 Contingent interest derivative — 958 — 958 Total liabilities measured at fair value $ — $ 958 $ 17,450 $ 18,408 December 31, 2015 Level 1 Level 2 Level 3 Fair Value Assets: Cash equivalents: Money market and other funds $ 46,867 $ — $ — $ 46,867 Time deposits — 3,004 — 3,004 Certificates of Deposit — 60 — 60 Equity securities 22,654 — — 22,654 Debt securities issued by the U.S. Treasury and other U.S. government corporations and agencies — 40,652 — 40,652 Debt securities issued by states of the United States and political subdivisions of the states — 6,103 — 6,103 Corporate debt securities — 88,749 — 88,749 Total assets measured at fair value $ 69,521 $ 138,568 $ — $ 208,089 Liabilities: Contingent consideration $ — $ — $ 30,600 $ 30,600 Contingent interest derivative — 1,450 — 1,450 Total liabilities measured at fair value $ — $ 1,450 $ 30,600 $ 32,050 At the end of each reporting period, management reviews the inputs to measure the fair value measurements of financial and non-financial assets and liabilities to determine when transfers between levels are deemed to have occurred. For the years ended December 31, 2016 and 2015, there were no transfers that have occurred between levels. The following tables presents a reconciliation of the Company’s Level 3 financial assets or liabilities that are measured at fair value on a recurring basis (in thousands): Level 3 Affected line item in the Statement of Income Balance as of January 1, 2015 $ 15,000 Contingent consideration (600 ) Not Applicable Total fair value adjustments reported in earnings 16,200 Balance as of December 31, 2015 $ 30,600 Contingent consideration $ — Total fair value adjustments reported in earnings 4,850 General and administrative Contingent consideration payments (18,000 ) Not Applicable Balance as of December 31, 2016 $ 17,450 In connection with the acquisition of Ookla, on December 1, 2014, contingent consideration of up to an aggregate of $40.0 million may be payable upon achieving certain future income thresholds and had a fair value of $17.0 million and $25.0 million at December 31, 2016 and 2015, respectively. Due to the Company achieving certain earnings targets for the year ended December 31, 2016, $20.0 million ( $17.0 million of contingent consideration and $3.0 million of compensation) has been reclassified to current liabilities on the consolidated balance sheet and is payable in the first quarter 2017. In connection with the acquisition of Salesify, on September 17, 2015, contingent consideration of up to an aggregate of $17.0 million may be payable upon achieving certain future income thresholds and had a fair value of $0.6 million and $5.6 million at December 31, 2016 and 2015, respectively, which was recorded as an other long-term liability on the consolidated balance sheet at December 31, 2016. During the year ended December 31, 2016, the Company recorded a net increase in the fair value of the contingent consideration of $4.9 million and reported such increase in general and administrative expenses. The following table presents a reconciliation of the Company’s derivative instruments (in thousands): Amount Affected line item in the Statement of Income Derivative Liabilities: Level 2: Balance as of January 1, 2015 $ 742 Total fair value adjustments reported in earnings 708 Interest expense, net Balance as of December 31, 2015 $ 1,450 Total fair value adjustments reported in earnings (492 ) Interest expense, net Balance as of December 31, 2016 $ 958 Losses associated with other-than-temporary impairments are recorded as a component of other income (expenses).

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill And Intangible Assets	Goodwill and Intangible Assets Goodwill represents the excess of the purchase price over the fair value of the net tangible and identifiable intangible assets acquired in a business combination. Intangible assets resulting from the acquisitions of entities accounted for using the purchase method of accounting are recorded at the estimated fair value of the assets acquired. Identifiable intangible assets are comprised of purchased customer relationships, trademarks and trade names, developed technologies and other intangible assets. The fair values of these identified intangible assets are based upon expected future cash flows or income, which take into consideration certain assumptions such as customer turnover, trade names and patent lives. These determinations are primarily based upon the Company’s historical experience and expected benefit of each intangible asset. If it is determined that such assumptions are not accurate, then the resulting change will impact the fair value of the intangible asset. Identifiable intangible assets are amortized over the period of estimated economic benefit, which ranges from one to 20 years. The changes in carrying amounts of goodwill for the year ended December 31, 2016 and 2015 are as follows (in thousands): Business Cloud Services Digital Media Consolidated Balance as of January 1, 2015 $ 390,063 $ 245,612 $ 635,675 Goodwill acquired 108,913 63,680 172,593 Purchase Accounting Adjustments 10,900 (4,289 ) 6,611 Foreign exchange translation (7,158 ) (60 ) (7,218 ) Balance as of December 31, 2015 $ 502,718 $ 304,943 $ 807,661 Goodwill acquired 69,202 263,988 333,190 Purchase accounting adjustments 816 (4,957 ) (4,141 ) Foreign exchange translation (13,584 ) (316 ) (13,900 ) Balance as of December 31, 2016 $ 559,152 $ 563,658 $ 1,122,810 Purchase accounting adjustments relate to adjustments to goodwill in connection with prior years business acquisitions. See Note 3 - Business Acquisitions - for a discussion related to purchase accounting adjustments. Intangible assets are summarized as of December 31, 2016 and 2015 as follows (in thousands): Intangible Assets with Indefinite Lives: 2016 2015 Trade names $ 27,379 $ 27,379 Other 5,432 5,432 Total $ 32,811 $ 32,811 In accordance with ASC 350, the Company performed the annual impairment test for goodwill for fiscal year 2016 using a qualitative assessment primarily taking into consideration macroeconomic, industry and market conditions, overall financial performance and any other relevant company-specific events. The Company performed the annual impairment test for intangible assets with indefinite lives for fiscal 2016 using a qualitative assessment primarily taking into consideration macroeconomic, industry and market conditions, overall financial performance and any other relevant company-specific events. j2 Global concluded that there were no impairments in 2016, 2015 and 2014.

Debt Disclosure [Text Block]	Long-Term Debt 8.0% Senior Notes On July 26, 2012 , the Company’s subsidiaries, issued in a private offering exempt from the registration requirements of the Securities Act of 1933, as amended, $250 million aggregate principal amount of 8.0% senior unsecured notes (the “Senior Notes”) due August 1, 2020 . j2 Cloud Services received proceeds of $245 million in cash, net of initial purchaser’s discounts and commissions of $5 million . The net proceeds were available for general corporate purposes, including acquisitions. Interest is payable semi-annually on February 1 and August 1 of each year. j2 Cloud Services has the option to call the Senior Notes in whole or in part after August 1, 2016 , subject to certain premiums as defined in the indenture governing the Senior Notes plus accrued and unpaid interest. Upon a change in control, the holders may put the Senior Notes at 101% of the principal amount of the Senior Notes plus accrued and unpaid interest, if any, to the repurchase date. In connection with the issuance of Convertible Notes (defined below), j2 Global, Inc. unconditionally guaranteed, on an unsecured basis, the obligations of j2 Cloud Services under the Senior Notes. The indenture governing the Senior Notes contains certain restrictive and other covenants applicable to j2 Cloud Services and subsidiaries designated as restricted subsidiaries including, but not limited to, limitations on debt and disqualified or preferred stock, restricted payments, liens, sale and leaseback transactions, dividends and other payment restrictions, asset sales and transactions with affiliates. Restricted payments are applicable only if j2 Cloud Services and subsidiaries designated as restricted subsidiaries have a pro forma leverage ratio of greater than 1.75 to 1.0. In addition, if such leverage ratio is in excess of 1.75 to 1.0, restricted payments are permitted up to $50 million. As of December 31, 2016 , j2 Cloud Services was in compliance with all such covenants. Violation of these covenants could result in a default which could result in the acceleration of outstanding amounts if such default is not cured or waived within the time periods outlined in the indenture. As of December 31, 2016 and 2015, the estimated fair value of the Senior Notes was approximately $275.4 million and $262.2 million , respectively, and was based on the quoted market prices of debt instruments with similar terms, credit rating and maturities of the Senior Notes as of December 31, 2016 and 2015, respectively. 3.25% Convertible Notes On June 10, 2014 , j2 Global issued $402.5 million aggregate principal amount of 3.25% convertible senior notes due June 15, 2029 (the “Convertible Notes”). j2 Global received proceeds of $391.4 million in cash, net of underwriters’ discounts and commissions. The net proceeds were available for general corporate purposes. The Convertible Notes bear interest at a rate of 3.25% per annum, payable semiannually in arrears on June 15 and December 15 of each year. Beginning with the six-month interest period commencing on June 15, 2021, the Company must pay contingent interest on the Convertible Notes during any six-month interest period if the trading price per $1,000 principal amount of the Convertible Notes for each of the five trading days immediately preceding the first day of such interest period equals or exceeds $1,300. Any contingent interest payable on the Convertible Notes will be in addition to the regular interest payable on the Convertible Notes. Holders may surrender their Convertible Notes for conversion at any time prior to the close of business on the business day immediately preceding the maturity date only if one or more of the following conditions is satisfied: (i) during any calendar quarter commencing after the calendar quarter ending on September 30, 2014 (and only during such calendar quarter), if the closing sale price of j2 Global common stock for at least 20 trading days in the period of 30 consecutive trading days ending on the last trading day of the calendar quarter immediately preceding the calendar quarter in which the conversion occurs is more than 130% of the applicable conversion price of the Convertible Notes on each such trading day; (ii) during the five consecutive business day period following any ten consecutive trading day period in which the trading price for the Convertible Notes for each such trading day was less than 98% of the product of (a) the closing sale price of j2 Global common stock on each such trading day and (b) the applicable conversion rate on each such trading day; (iii) if j2 Global calls any or all of the Convertible Notes for redemption, at any time prior to the close of business on the business day prior to the redemption date; (iv) upon the occurrence of specified corporate events; or (v) during either the period beginning on, and including, March 15, 2021 and ending on, but excluding, June 20, 2021 or the period beginning on, and including, March 15, 2029 and ending on, but excluding, the maturity date. j2 Global will settle conversions of Convertible Notes by paying or delivering, as the case may be, cash, shares of j2 Global common stock or a combination thereof at j2 Global’s election. The Company currently intends to satisfy its conversion obligation by paying and delivering a combination of cash and shares of the Company’s common stock, where cash will be used to settle each $1,000 of principal and the remainder, if any, will be settled via shares of the Company’s common stock. As of December 31, 2016, the conversion rate is 14.5078 shares of j2 Global common stock for each $1,000 principal amount of Convertible Notes, which represents a conversion price of approximately $68.93 per share of j2 Global common stock. The conversion rate is subject to adjustment for certain events as set forth in the indenture governing the Convertible Notes, but will not be adjusted for accrued interest. In addition, following certain corporate events that occur on or prior to June 20, 2021, j2 Global will increase the conversion rate for a holder that elects to convert its Convertible Notes in connection with such a corporate event. j2 Global may not redeem the Convertible Notes prior to June 20, 2021. On or after June 20, 2021, j2 Global may redeem for cash all or part of the Convertible Notes at a redemption price equal to 100% of the principal amount of the Convertible Notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date. No sinking fund is provided for the Convertible Notes. Holders have the right to require j2 Global to repurchase for cash all or part of their Convertible Notes on each of June 15, 2021 and June 15, 2024 at a repurchase price equal to 100% of the principal amount of the Convertible Notes to be repurchased, plus accrued and unpaid interest to, but excluding, the relevant repurchase date. In addition, if a fundamental change, as defined in the indenture governing the Convertible Notes, occurs prior to the maturity date, holders may require j2 Global to repurchase for cash all or part of their Convertible Notes at a repurchase price equal to 100% of the principal amount of the Convertible Notes to be repurchased, plus accrued and unpaid interest to, but excluding, the fundamental change repurchase date. The Convertible Notes are the Company’s general senior unsecured obligations and rank: (i) senior in right of payment to any of the Company’s future indebtedness that is expressly subordinated in right of payment to the Convertible Notes; (ii) equal in right of payment to the Company’s existing and future unsecured indebtedness that is not so subordinated, including in respect of j2 Global’s guarantee of the obligations of our subsidiary, j2 Cloud Services, with respect to its outstanding Senior Notes; (iii) effectively junior in right of payment to any of the Company’s secured indebtedness to the extent of the value of the assets securing such indebtedness; and (iv) structurally junior to all existing and future indebtedness (including trade payables) incurred by the Company’s subsidiaries. Accounting for the Convertible Notes In accordance with ASC 470-20, Debt with Conversion and Other Options, convertible debt that can be settled for cash is required to be separated into the liability and equity component at issuance, with each component assigned a value. The value assigned to the liability component is the estimated fair value, as of the issuance date, of similar debt without the conversion feature. The difference between the cash proceeds and estimated fair value of the liability component, representing the value of the conversion premium assigned to the equity component, is recorded as a debt discount on the issuance date. This debt discount is amortized to interest expense using the effective interest method over the period from the issuance date through the first stated repurchase date on June 15, 2021. j2 Global estimated the borrowing rates of similar debt without the conversion feature at origination to be 5.79% for the Convertible Notes and determined the debt discount to be $59.0 million . As a result, a conversion premium after tax of $37.7 million was recorded in additional paid-in capital. The aggregate debt discount is amortized as interest expense over the period from the issuance date through the first stated repurchase date on June 15, 2021 which management believes is the expected life of the Convertible Notes using an interest rate of 5.81% . As of December 31, 2016 , the remaining period over which the unamortized debt discount will be amortized is 4.5 years . The Convertible Notes are carried at face value less any unamortized debt discount. The fair value of the Convertible Notes at each balance sheet date is determined based on recent quoted market prices or dealer quotes for the Convertible Notes, which are Level 1 inputs (see Note 5 - Fair Value Measurements). If such information is not available, the fair value is determined using cash-flow models of the scheduled payments discounted at market interest rates for comparable debt without the conversion feature. As of December 31, 2016 and 2015, the estimated fair value of the Convertible Notes was approximately $516.8 million and $528.3 million , respectively. As of December 31, 2016 and 2015, the if-converted value of our Convertible Notes exceeded the principal amount of $402.5 million by $75.2 million and $76.2 million , respectively. The following table provides additional information related to our Convertible Notes (in thousands): 2016 2015 Additional paid-in capital $ 37,700 $ 37,700 Principal amount of Convertible Notes $ 402,500 $ 402,500 Unamortized discount of the liability component 40,356 48,064 Carrying amount of debt issuance costs 7,002 8,219 Net carrying amount of Convertible Notes $ 355,142 $ 346,217 The following table provides the components of interest expense related to our Convertible Notes (in thousands): 2016 2015 2014 Cash interest expense (coupon interest expense) $ 13,081 $ 13,081 $ 6,980 Non-cash amortization of discount on Convertible Notes 7,707 7,274 3,712 Amortization of debt issuance costs 1,217 1,109 551 Total interest expense related to Convertible Notes $ 22,005 $ 21,464 $ 11,243 Long-term debt as of December 31, 2016 and 2015 consists of the following (in thousands): 2016 2015 Senior Notes $ 247,359 $ 246,750 Convertible Notes 362,144 354,436 Less: Deferred issuance costs (1) (7,757 ) (9,149 ) Total long-term debt $ 601,746 $ 592,037 Less: Current portion — — Total long-term debt, less current portion $ 601,746 $ 592,037 (1) The Company adopted ASU 2015-03 Interest - Imputation Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs during the first quarter of 2016 on a retrospective basis.

Commitments And Contingencies	Commitments and Contingencies Litigation From time to time, j2 Global and its affiliates are involved in litigation and other legal disputes or regulatory inquiries that arise in the ordinary course of business. Any claims or regulatory actions against j2 Global and its affiliates, whether meritorious or not, could be time consuming and costly, and could divert significant operational resources. The outcomes of such matters are subject to inherent uncertainties, carrying the potential for unfavorable rulings that could include monetary damages and injunctive relief. On February 17, 2011, Emmanuel Pantelakis (“Pantelakis”) filed suit against a j2 Global affiliate in the Ontario Superior Court of Justice (No. 11-50673), alleging that the j2 Global affiliate breached a contract relating to Pantelakis’s use of the Campaigner ® service. The j2 Global affiliate filed a responsive pleading on March 23, 2011 and responses to undertakings on July 16, 2012. On November 6, 2012, Pantelakis filed a second amended statement of claim, reframing his lawsuit as a negligence action. The j2 Global affiliate filed an amended statement of defense on April 8, 2013. Discovery is ongoing. On January 17, 2013, the Commissioner of the Massachusetts Department of Revenue (“Commissioner”) issued a notice of assessment to a j2 Global affiliate for sales and use tax for the period of July 1, 2003 through December 31, 2011. On July 22, 2014, the Commissioner denied the j2 Global affiliate’s application for abatement. On September 18, 2014, the j2 Global affiliate petitioned the Massachusetts Appellate Tax Board for abatement of the tax asserted in the notice of assessment (No. C325426). A trial was held on December 16, 2015. The Massachusetts Appellate Tax Board has not yet rendered its decision. On January 18, 2013, Paldo Sign and Display Co. filed an amended complaint adding two j2 Global affiliates and a former employee as additional defendants in an existing putative class action pending in the U.S. District Court for the Northern District of Illinois (the “Northern District of Illinois”) (No. 1:13-cv-01896). The amended complaint alleged violations of the Telephone Consumer Protection Act (“TCPA”), the Illinois Consumer Fraud and Deceptive Business Practices Act (“ICFA”), and common law conversion, arising from an indirect customer’s alleged use of a j2 Global affiliate’s systems to send unsolicited facsimile transmissions. The j2 Global affiliates filed a motion to dismiss the ICFA and conversion claims, which was granted. The Northern District of Illinois also dismissed the former employee for lack of personal jurisdiction. On August 23, 2013, a second plaintiff, Sabon, Inc., was added. On March 7, 2016, the j2 Global affiliates moved for summary judgment on all remaining claims. The summary judgment motions are pending. The Northern District of Illinois has not yet addressed class certification. On August 28, 2013, Phyllis A. Huster (“Huster”) filed suit in the Northern District of Illinois (No. 1:13-cv-06143) against two j2 Global affiliates and three other parties for correction of inventorship for nine j2 Global patents. Huster seeks, among other things, a declaration that she was an inventor of the patents-in-suit, an order directing the U.S. Patent & Trademark Office to substitute or add her as an inventor, and payment of at least half of defendants’ earnings from licensing the patents-in-suit. On September 19, 2014, the Northern District of Illinois granted the defendants’ motion to dismiss for improper venue and transferred the case to the U.S. District Court for the Northern District of Georgia (the “Northern District of Georgia”) (No. 1:14-cv-03304). Huster filed an amended complaint on February 11, 2015, which she corrected on February 12, 2015. The corrected amended complaint added various common law claims. On November 12, 2015, the Northern District of Georgia dismissed all claims against the j2 Global affiliates. On January 28, 2016, all remaining claims were dismissed on summary judgment. Huster filed a notice of appeal to the U.S. Court of Appeals for the Federal Circuit (the “Federal Circuit”) on February 26, 2016 (No. 16-1639). The appeal is pending. On October 16, 2013, a j2 Global affiliate entered an appearance as a plaintiff in a multi-district litigation pending in the Northern District of Illinois (No. 1:12-cv-06286). In this litigation, Unified Messaging Solutions, LLC (“UMS”), a company with rights to assert certain patents owned by the j2 Global affiliate, has asserted five j2 Global patents against a number of defendants. While claims against some defendants have been settled, other defendants have filed counterclaims for, among other things, non-infringement, unenforceability, and invalidity of the patents-in-suit. On December 20, 2013, the Northern District of Illinois issued a claim construction opinion and, on June 13, 2014, entered a final judgment of non-infringement for the remaining defendants based on that claim construction. UMS and the j2 Global affiliate filed a notice of appeal to the Federal Circuit on June 27, 2014 (No. 14-1611). The appeal is pending. On June 23, 2014, Andre Free-Vychine (“Free-Vychine”) filed a putative class action against two j2 Global affiliates in the Superior Court for the State of California, County of Los Angeles (“Los Angeles Superior Court”) (No. BC549422). The complaint alleged two California statutory violations relating to late fees levied in certain eVoice® accounts. Free-Vychine sought, among other things, damages and injunctive relief on behalf of himself and a purported nationwide class of similarly situated persons. On August 26, 2014, Law Enforcement Officers, Inc. (“LEO”) and IV Pit Stop, Inc. (“IV Pit Stop”) filed a separate putative class action against the same j2 Global affiliates in Los Angeles Superior Court (No. BC555721). The complaint alleged three California statutory violations, negligence, breach of the implied covenant of good faith and fair dealing, and various other common law claims relating to late fees levied on any of the j2 Global affiliates’ customers, including those with eVoice® and Onebox® accounts. LEO and IV Pit Stop sought, among other things, damages and injunctive relief on behalf of themselves and a purported nationwide class of similarly situated persons. On September 29, 2014, the Los Angeles Superior Court related and consolidated both cases for discovery purposes. On March 13, 2015, a third amended complaint was filed in the case brought by LEO, which no longer included IV Pit Stop as a plaintiff but added Christopher Dancel (“Dancel”) as a plaintiff. On June 26, 2015, the case filed by Free-Vychine was dismissed pursuant to a settlement agreement. On October 7, 2015, the parties in the case brought by LEO and Dancel reached a tentative class-based settlement. On September 12, 2016, the Los Angeles Superior Court certified the class for settlement purposes only and provided its preliminary approved the settlement. The court will consider final approval of the settlement in early 2017. On January 21, 2016, Davis Neurology, P.A. filed a putative class action against two j2 Global affiliates in the Circuit Court for the County of Pope, State of Arkansas (58-cv-2016-40), alleging violations of the TCPA. The case was ultimately removed to the U.S. District Court for the Eastern District of Arkansas (No. 4:16-cv-00682). On June 6, 2016, the j2 Global affiliates filed a motion for judgment on the pleadings. That motion is fully briefed and pending before the court. j2 Global does not believe, based on current knowledge, that the foregoing legal proceedings or claims, after giving effect to existing reserves, are likely to have a material adverse effect on the Company’s consolidated financial position, results of operations, or cash flows. However, depending on the amount and timing, an unfavorable resolution of some or all of these matters could have a material effect on j2 Global’s consolidated financial position, results of operations, or cash flows in a particular period. The Company has not accrued for any material loss contingencies relating to these legal proceedings because unfavorable outcomes are not considered probable by management. It is the Company’s policy to expense as incurred legal fees related to various litigations. Credit Agreement On December 5, 2016, j2 Global, Inc. entered into a Credit Agreement (the “Credit Agreement”) with MUFG Union Bank, N.A., as administrative agent, and certain other lenders from time to time party thereto (collectively, the “Lenders”). Pursuant to the Credit Agreement, the Lenders have provided j2 with a credit facility of $225.0 million (the “Credit Facility”). $180.0 million of which was drawn at closing of the Everyday Health acquisition and used to finance a portion of the cash consideration in the acquisition (see Note 3 - Business Acquisitions) reducing the amount available to the Company to borrow to $45.0 million . The Company must repay $30.0 million six months subsequent to the Closing Date. At the Company’s option, amounts borrowed under the Credit Agreement will bear interest at either (i) the London interbank offered rate multiplied by the Statutory Reserve Rate (as defined in the Credit Agreement) (the “Eurocurrency Rate”) or (ii) a base rate (the “Base Rate”) equal to the highest of (x) the federal funds rate, plus 0.50%, (y) the Reference Rate (as defined in the Credit Agreement) then in effect and (z) the Eurocurrency Rate for an interest period of one month, plus 1.0%, in each case, plus an applicable margin. Until the date that is six months after the Closing Date, the applicable margin relating to any Eurocurrency Rate loan is 1.75% and the applicable margin relating to any Base Rate loan is 0.75%. From and after the date that is six months after the Closing Date, the applicable margin relating to any Eurocurrency Rate loan is 2.25% and the applicable margin relating to any Base Rate loan is 1.25%. The final maturity of the Credit Facility will occur on December 4, 2017 (the “Maturity Date”). j2 Global is permitted to make voluntary prepayments of the Credit Facility at any time without payment of a premium or penalty. Amounts repaid cannot be re-borrowed. The Company is required to make mandatory prepayments of loans under the Credit Facility with (i) net cash proceeds from issuances of debt (other than certain permitted debt), (ii) net cash proceeds from certain non-ordinary course asset sales (subject to reinvestment rights and other exceptions) and (iii) casualty proceeds and condemnation awards (subject to reinvestment rights and other exceptions). The Company is also required to make prepayments of loans under the Credit Facility in the amount equal to the then-outstanding loans under the Credit Facility minus $150.0 million, if on the date that is six months after the Closing Date, the aggregate principal amount of the loans under the Credit Facility is greater than $150.0 million. The obligations under the Credit Facility and certain cash management and hedging obligations are and will be fully and unconditionally guaranteed by certain of j2 Global’s existing and subsequently acquired or organized direct and indirect subsidiaries (including Ziff Davis, LLC and Everyday Health) pursuant to a guarantee agreement and secured by a lien on the equity interests of certain of j2 Global’s subsidiaries, subject to customary exceptions. The Credit Agreement contains financial maintenance covenants, including maintenance of (i) a maximum total leverage ratio as of the last date of any fiscal quarter not to exceed 3.25:1.00; and (ii) a minimum Consolidated EBITDA (as defined in the Credit Agreement) of not less than $75.0 million for any fiscal quarter. The Credit Agreement also contains restrictive covenants that limit, among other things, the Company’s and its restricted subsidiaries’ ability to incur additional indebtedness, create, incur or assume liens, consolidate, merge, liquidate or dissolve, pay dividends or make other distributions or other restricted payments, make or hold any investments, enter into certain transactions with affiliates, sell assets other than on terms specified by the Credit Agreement, amend the terms of certain other indebtedness and organizational documents and change their lines of business and fiscal years, in each case, subject to customary exceptions. j2 Global was in compliance with all such covenants. The Credit Agreement also sets forth customary events of default, including, among other things, the failure to make timely payments under the Credit Facility, the failure to satisfy certain covenants, cross-default and cross-acceleration to other material debt for borrowed money, the occurrence of a change of control and specified events of bankruptcy and insolvency. The Company has capitalized the total of $1.3 million in debt issuance costs, which are being amortized to interest expense over the life of the Credit Facility. As of December 31, 2016 , these debt issuance costs, net of amortization, were $1.2 million . The related interest expense was $0.3 million for the year ended December 31, 2016 . Operating Leases j2 Global leases certain facilities and equipment under non-cancelable operating leases which expire at various dates through 2025. Office and equipment leases are typically for terms of three to five years and generally provide renewal options for terms up to an additional five years. In most cases, the Company expects leases that expire will be renewed or replaced by other leases with similar terms. Future minimum lease payments at December 31, 2016 under non-cancelable operating leases (with initial or remaining lease terms in excess of one year) are as follows (in thousands): Lease Payments Fiscal Year: 2017 $ 14,799 2018 13,823 2019 12,025 2020 8,799 2021 7,929 Thereafter 16,845 Total minimum lease payments $ 74,220 Rental expense for the years ended December 31, 2016 , 2015 and 2014 was $10.6 million , $9.0 million and $9.7 million , respectively. Sublease Total sublease income for the years ended December 31, 2016 , 2015 and 2014 was $0.6 million and $0.5 million and $0.1 million , respectively. Total estimated aggregate sublease income to be received in the future is $1.3 million . Capital Leases As of December 31, 2016 and 2015 , assets held under capital leases are as follows (in thousands): 2016 2015 Capital leases $ 1,967 $ 870 Less: Accumulated depreciation (1,915 ) (617 ) Total capital leases, net $ 52 $ 253 Future minimum payments at December 31, 2016 under all capital leases (with initial or remaining lease terms in excess of one year) are as follows (in thousands): Future Payments Fiscal Year: 2017 $ 53 2018 11 2019 — 2020 — 2021 — Thereafter — Total minimum lease payments $ 64 Depreciation expense under capital leases for the years ended December 31, 2016 , 2015 and 2014 was $0.3 million , $0.2 million and $0.4 million , respectively. Non-Income Related Taxes As a provider of cloud services for business, the Company does not provide telecommunications services. Thus, it believes that its business and its users (by using our services) are generally not subject to various telecommunication taxes. Moreover, the Company generally does not believe that its business and its users (by using our services) are subject to other indirect taxes, such as sales and use tax, business tax and gross receipt tax. However, several state and municipal taxing authorities have challenged these beliefs and have and may continue to audit and assess our business and operations with respect to telecommunications and other indirect taxes. On February 24, 2016, President Obama signed into law H.R. 644, the “Trade Facilitation and Trade Enforcement Act of 2015” which included a provision to permanently ban state and local authorities from imposing access or discriminatory taxes on the Internet. The new law allows “grandfathered” states and local authorities to continue their existing taxes on internet access through June 2020. The Company is currently under audit for indirect taxes in several states and municipalities. On February 27, 2013, the Office of Finance for the City of Los Angeles (the “Los Angeles Office of Finance”) issued assessments to a j2 Global affiliate for business and communications taxes for the period of January 1, 2009 through December 31, 2012. On September 11, 2014, the Los Angeles Office of Finance issued revised assessments to a j2 Global affiliate increasing such affiliate’s liability to the City of Los Angeles. On April 30, 2015, the Los Angeles Office of Finance Board of Review denied the j2 Global affiliate’s request to abate the assessments. The j2 Global affiliate paid the assessments and requested the abatement of penalties. On November 2, 2016, the j2 Global affiliate reached an agreement with the City of Los Angeles to obtain a refund of a portion of the assessments paid. The refund was received December 1, 2016. In addition, on August 24, 2016, the Los Angeles Office of Finance notified the j2 Global affiliate that it will commence an audit of business and communications taxes for the period January 1, 2013 through December 31, 2016. For other jurisdictions, we currently have no reserves established for these matters, as we have determined that the liability is not probable and estimable. However, it is reasonably possible that such a liability could be incurred, which would result in additional expense, which could materially impact our financial results.

Temporary differences and carryforwards which give rise to deferred tax assets and liabilities are as follows (in thousands): Years Ended December 31, 2016 2015 Deferred tax assets: Net operating loss carryforwards $ 59,806 $ 11,559 Tax credit carryforwards 16,281 18,341 Accrued expenses 14,759 12,156 Allowance for bad debt 2,624 1,169 Share-based compensation expense 5,631 4,308 Basis difference in fixed assets 2,195 — Impairment of investments 74 74 Deferred revenue 2,361 3,232 State taxes 1,758 522 Other 9,227 7,458 114,716 58,819 Less: valuation allowance (12,028 ) (14,242 ) Total deferred tax assets $ 102,688 $ 44,577 Deferred tax liabilities: Basis difference in fixed assets $ — $ (5,457 ) Basis difference in intangible assets (98,830 ) (41,351 ) Prepaid insurance (246 ) (482 ) Convertible debt (36,592 ) (31,091 ) Other (2,088 ) (3,330 ) Total deferred tax liabilities (137,756 ) (81,711 ) Net deferred tax liabilities $ (35,068 ) $ (37,134 ) The Company had approximately $102.7 million and $44.6 million in deferred tax assets as of December 31, 2016 and 2015 , respectively, related primarily to net operating loss carryforwards, tax credit carryforwards and accrued expenses treated differently between its financial statements and its tax returns. Based on the weight of available evidence, the Company assesses whether it is more likely than not that some portion or all of a deferred tax asset will not be realized. If necessary, j2 Global records a valuation allowance sufficient to reduce the deferred tax asset to the amount that is more likely that not to be realized. The deferred tax assets should be realized through future operating results and the reversal of temporary differences. As of December 31, 2016 , the Company had federal net operating loss carryforwards (“NOLs”) of $144.0 million , after considering substantial restrictions on the utilization of these NOLs due to “ownership changes”, as defined in the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”). j2 Global currently estimates that all of the above-mentioned federal NOLs will be available for use before their expiration. These NOLs expire through the year 2036 . The $144.0 million NOL carryforward amount includes $130.6 million acquired pursuant to the Everyday Health transaction (see Note 3 - Business Acquisitions). As of December 31, 2016 , the Company had credits for Alternative Minimum Tax (“AMT”) of $0.9 million which was acquired pursuant to the Everyday Health transaction. The AMT credits have an indefinite life; however, these credits are subject to utilization restrictions similar to the restrictions placed on NOL utilization. As of December 31, 2016 and 2015 , the Company has foreign tax credits of $11.9 million and $14.0 million , respectively. The Company has provided a valuation allowance on the foreign tax credits of $11.9 million and $14.0 million , respectively, as the weight of available evidence does not support full utilization of these credits. The foreign tax credits expire through the year 2025. In addition, as of December 31, 2016 and 2015 , the Company had state research and development tax credits of $3.5 million and $3.7 million , respectively, which last indefinitely. As of December 31, 2016 and 2015 , the Company had state enterprise zone tax credits of zero and $0.6 million , respectively. Certain tax payments are prepaid during the year and included within prepaid expenses and other current assets on the consolidated balance sheet. The Company’s prepaid tax payments were zero and $11.6 million at December 31, 2016 and 2015 , respectively. Uncertain Income Tax Positions Tax positions are evaluated in a two-step process. The Company first determines whether it is more likely than not that a tax position will be sustained upon examination. If a tax position meets the more-likely-than-not recognition threshold, it is then measured to determine the amount of benefit to recognize in the financial statements. The tax position is measured as the largest amount of benefit that is greater than 50% likely of being realized upon ultimate settlement. The Company classifies gross interest and penalties and unrecognized tax benefits that are not expected to result in payment or receipt of cash within one year as non-current liabilities in the consolidated balance sheets. As of December 31, 2016 , the total amount of unrecognized tax benefits was $41.2 million , of which $37.0 million , if recognized, would affect the Company’s effective tax rate. As of December 31, 2015, the total amount of unrecognized tax benefits was $32.5 million , of which $29.8 million , if recognized, would affect the Company’s effective tax rate. As of December 31, 2014, the total amount of unrecognized tax benefits was $34.6 million , of which $32.7 million , if recognized would affect the Company’s effective tax rate. The aggregate changes in the balance of unrecognized tax benefits, which excludes interest and penalties, for 2016 , 2015 and 2014 , is as follows (in thousands): Years Ended December 31, 2016 2015 2014 Beginning balance $ 32,536 $ 34,635 $ 40,888 Increases related to tax positions during a prior year 2,082 10,361 919 Decreases related to tax positions taken during a prior year — (17,107 ) (8,284 ) Increases related to tax positions taken in the current year 6,703 8,841 3,765 Settlements — (4,194 ) (1,524 ) Decreases related to expiration of statute of limitations (103 ) — (1,129 ) Ending balance $ 41,218 $ 32,536 $ 34,635 The Company includes interest and penalties related to unrecognized tax benefits within the provision for income taxes. As of December 31, 2016 , 2015 and 2014 , the total amount of interest and penalties accrued was $5.3 million , $3.4 million and $2.9 million , respectively, which is classified as non-current liabilities in the consolidated balance sheets. In connection with tax matters, the Company recognized interest and penalty (benefit) expense in 2016 , 2015 and 2014 of $1.9 million , $(1.4) million and $(0.1) million , respectively. Uncertain income tax positions are reasonably possible to significantly change during the next 12 months as a result of completion of income tax audits and expiration of statutes of limitations. At this point it is not possible to provide an estimate of the amount, if any, of significant changes in reserves for uncertain income tax positions as a result of the completion of income tax audits that are reasonably possible to occur in the next 12 months. In addition, the Company cannot currently estimate the amount of, if any, uncertain income tax positions which will be released in the next 12 months as a result of expiration of statutes of limitations due to ongoing audits. As a result of ongoing federal, state and foreign income tax audits (discussed below), it is reasonably possible that our entire reserve for uncertain income tax positions for the periods under audit will be released. It is also reasonably possible that the Company’s reserves will be inadequate to cover the entire amount of any such income tax liability. The Company has not provided U.S. income taxes and foreign withholding taxes on the undistributed earnings of foreign subsidiaries as of December 31, 2016 because it intends to permanently reinvest such earnings outside the U.S. If these foreign earnings were to be repatriated in the future, the related U.S. tax liability may be reduced by any foreign income taxes previously paid on these earnings and would generate foreign tax credits that would reduce the federal tax liability. As of December 31, 2016 , the cumulative amount of earnings upon which U.S. income taxes have not been provided is approximately $540.0 million . Determination of the amount of unrecognized deferred tax liability related to these earnings is not practicable. Income before income taxes included income from domestic operations of $84.8 million , $61.0 million and $79.4 million for the year ended December 31, 2016, 2015 and 2014, respectively, and income from foreign operations of $126.6 million , $95.9 million and $75.8 million for the year ended December 31, 2016, 2015 and 2014, respectively. Income Tax Audits: In November 2015, the U.S. Internal Revenue Service (“IRS”) began an income tax audit of the Company’s 2012 and 2013 tax years. In March 2016, the IRS expanded its income tax audit to include the Company’s 2014 tax year. j2 Global is under income tax audit by the California Franchise Tax Board (the “FTB”) for its tax years 2012 and 2013. The FTB, however, has agreed to suspend its audit for 2012 and 2013 pending the outcome of the IRS audit for such tax years. The Company is under income tax audit by the New York State Department of Taxation and Finance for tax years 2011 through 2013. j2 Global was under income tax audit by the New York City Department of Finance (“NYC”) for its tax years 2009 through 2011. In February 2016, j2 Global settled its NYC audit for approximately $26,000 . It is reasonably possible that these audits may conclude in the next 12 months and that the uncertain tax positions the Company has recorded in relation to these tax years may change compared to the liabilities recorded for these periods. If the recorded uncertain tax positions are inadequate to cover the associated tax liabilities, the Company would be required to record additional tax expense in the relevant period, which could be material. If the recorded uncertain tax positions are adequate to cover the associated tax liabilities, the Company would be required to record any excess as reduction in tax expense in the relevant period, which could be material. However, it is not currently possible to estimate the amount, if any, of such change.

Stockholders' Equity Note [Abstract]
Stockholders' Equity	Stockholders’ Equity j2 Preferred Stock In connection with the December 31, 2013 reorganization of Ziff Davis, Inc. (“ZD Inc.”) into Ziff Davis, LLC (“ZD LLC”) and the Company’s acquisition of all of the minority holders’ equity interests in ZD Inc., the Company issued j2 Series A Preferred Stock (“j2 Series A Stock”) and j2 Series B Preferred Stock (“j2 Series B Stock”). j2 Series A Stock Each share of j2 Series A Stock has a stated value of $1,000 . The j2 Series A Stock is not convertible into any other securities. In the event ZD LLC pays any dividends or distributions to the Company in respect of the Company’s membership interests in ZD LLC (subject to certain exceptions in respect of senior interests), holders of the j2 Series A Stock will be entitled to receive a dividend in the aggregate with respect to all j2 Series A Stock equal to 2.4449% of such ZD LLC dividend (but only to the extent such dividend and all other dividends paid in respect of the series A preferred stock does not exceed a compounded annual rate of 15% on the stated value of the j2 Series A Stock). The j2 Series A Stock has a liquidation preference over the j2 Series B Stock and a liquidation preference over j2 common stock in an amount up to, with respect to all shares of j2 Series A Stock, 2.4449% of the assets of ZD LLC and its subsidiaries legally available for distribution to the Company, after reduction in respect of certain senior interests (the “series A minority portion”), but in no event in an amount that exceeds the stated value of the j2 Series A Stock increased at a compounded annual rate of 15% (the “series A cap”) and in no event in an amount that exceeds the lesser of the Company’s assets available for distribution and 2.4449% of the assets of ZD LLC and its subsidiaries legally available for distribution to the Company. On or after January 2, 2019, the j2 Series A Stock will be mandatorily redeemable by the Company upon the occurrence of certain contingent liquidity events such as a sale, initial public offering or spin-off transactions involving ZD, LLC. Any or all of the j2 Series A Stock is subject to redemption by the Company at its option at any time. If the redemption occurs in connection with certain sale, initial public offering or spin-off transactions involving ZD LLC, the redemption price will be equal to an allocable portion of the enterprise value of ZD, LLC implied by such transaction with respect to the series A minority portion and based on certain factors to be determined by the Company’s Board of Directors in its sole good faith judgment, but in no event in an amount that would exceed the series A cap. If not in connection with such a transaction, the redemption price will be the series A cap. j2 Series B Stock The j2 Series B Stock is not convertible into any other securities. In the event ZD LLC pays any dividends or distributions to the Company in respect of the Company’s membership interests in ZD LLC (subject to certain exceptions in respect of senior interests and the j2 Series A Stock), holders of the j2 series B preferred stock will be entitled to receive a dividend in the aggregate with respect to all j2 Series B Stock equal to 9.5579% of such ZD LLC dividend. The j2 Series B Stock will have a liquidation preference junior to the liquidation preference of the j2 Series A Stock and a liquidation preference over the j2 common stock in an amount up to, with respect to all shares of j2 Series B Stock, 9.5579% of the assets of ZD LLC and its subsidiaries legally available for distribution to the Company, after reduction in respect of the j2 Series A Stock and certain other senior interests (the “series B minority portion”), but in no event in an amount that exceeds the lesser of the Company’s assets available for distribution and 9.5579% of the assets of ZD LLC and its subsidiaries legally available for distribution to the Company. On or after January 2, 2019, the j2 Series B Stock will be mandatorily redeemable by the Company upon the occurrence of certain contingent liquidity events such as a sale, initial public offering or spin-off transactions involving ZD LLC. Any or all of the j2 Series B Stock is subject to redemption by the Company at its option at any time. If the redemption occurs in connection with certain sale, initial public offering or spin-off transactions involving ZD LLC, the redemption price will be equal to an allocable portion of the enterprise value of ZD LLC implied by such transaction with respect to the series B minority portion and based on certain factors to be determined by the Board of Directors of the Company in its sole good faith judgment. Otherwise, the redemption price will be equal to the fair market value of such share as determined by the Company’s Board of Directors in its sole good faith judgment. Preferred Stock Exchange In November 2014, the Company provided holders of j2 Series A Stock and j2 Series B Stock an exchange right in which shares may be exchanged for j2 common stock. The exchange right associated with the shares of j2 Series A Stock were immediately exercisable at an exchange ratio of 20.4319 shares of j2 common stock per share of j2 Series A Stock (the “Series A Exchange Ratio”). Both holders of the j2 Series A Stock exercised this exchange right which resulted in the issuance of 235,665 shares of j2 common stock. The exchange right associated with the vested shares of the j2 Series B Stock is exercisable during specified exchange periods at an exchange ratio of 31.8094 shares of j2 common stock per share of j2 Series B Stock (the “Series B Exchange Ratio”). Holders of vested j2 Series B Stock exercised this exchange right which resulted in the issuance of 91,737 and 91,734 shares of j2 common stock during fiscal years 2016 and 2015 , respectively. In connection with the exercise of the exchange right and the resulting extinguishment of the Series A, the Company recorded the difference between the carrying value of the Series A and the fair value of the j2 common stock exchanged within retained earnings as a preferred stock dividend. In connection with the exercise of the exchange right associated with Series B, the Company recognized incremental fair value in the amount of $6.3 million and recorded additional share-based compensation in the amount of $1.3 million and $1.6 million for the years ended December 31, 2016 and 2015, respectively. The remaining amount of unrecognized incremental fair value will be recognized over the remaining service period. The Series B Exchange Ratio is adjusted in the event of a subdivision of the outstanding j2 common stock or j2 Series B Stock, a declaration of a dividend payable in shares of j2 common stock or j2 Series B Stock, a declaration of a dividend payable in a form other than shares in an amount that has a material effect on the value of shares of j2 common stock or j2 Series B Stock, a combination or consolidation of the outstanding j2 common stock or j2 Series B Stock into a lesser number of shares of j2 common stock or j2 Series B Stock, respectively, specified changes in control, a recapitalization, a reclassification, or a similar occurrence, the Company shall adjust the Series B Exchange Ratio as it deems appropriate in its sole discretion. Common Stock Repurchase Program In February 2012, the Company’s Board of Directors approved a program authorizing the repurchase of up to five million shares of j2 Global common stock through February 20, 2013 (the “2012 Program”) which was subsequently extended through February 19, 2018. On February 15, 2012, the Company entered into a Rule 10b5-1 trading plan with a broker to facilitate the repurchase program. No shares were repurchased under the share repurchase program for the year ended December 31, 2016 and 2015. Cumulatively at December 31, 2016 , 2.1 million shares were repurchased at an aggregate cost of $58.6 million (including an immaterial amount of commission fees). In July 2016, the Company acquired and subsequently retired 935,231 shares of j2 Global common stock in connection with the acquisition of Integrated Global Concepts, Inc. (see Note 3 - Business Acquisitions). As a result of the purchase of j2 Global common stock, the Company’s Board of Directors approved a reduction in the number of shares available for purchase under the 2012 Program by the same amount leaving 1,938,689 shares of j2 Global common stock available for purchase under this program. Periodically, participants in j2 Global’s stock plans surrender to the Company shares of j2 Global stock to pay the exercise price or to satisfy tax withholding obligations arising upon the exercise of stock options or the vesting of restricted stock. During the year ended December 31, 2016 , the Company purchased 80,353 shares from plan participants for this purpose.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock Options And Employee Stock Purchase Plan	Stock Options and Employee Stock Purchase Plan j2 Global’s share-based compensation plans include the Second Amended and Restated 1997 Stock Option Plan, the 2007 Stock Plan, the 2015 Stock Plan and the 2001 Employee Stock Purchase Plan. Each plan is described below. (a) Second Amended and Restated 1997 Stock Option Plan, the 2007 Stock Option Plan and the 2015 Stock Option Plan In November 1997, j2 Global’s Board of Directors adopted the j2 Global Communications, Inc. 1997 Stock Option Plan, which was twice amended and restated (the “1997 Plan”). The 1997 Plan terminated in 2007, although stock options and restricted stock issued under the 1997 Plan continue to be governed by it. A total of 12,000,000 shares of common stock were authorized to be used for 1997 Plan purposes. An additional 840,000 shares were authorized for issuance upon exercise of options granted outside the 1997 Plan. In October 2007, j2 Global’s Board of Directors adopted the j2 Global, Inc. 2007 Stock Option Plan (the “2007 Plan”). The 2007 Plan provides for the granting of incentive stock options, nonqualified stock options, stock appreciation rights, restricted stock, restricted stock units and other share-based awards. The number of authorized shares of common stock that may be used for 2007 Plan purposes is 4,500,000 . Options under the 2007 Plan may be granted at exercise prices determined by the Board of Directors, provided that the exercise prices shall not be less than the fair market value of j2 Global’s common stock on the date of grant for incentive stock options and not less than 85% of the fair market value of j2 Global’s common stock on the date of grant for non-statutory stock options. In May 2015, j2 Global’s Board of Directors adopted the j2 Global, Inc. 2015 Stock Option Plan (the “2015 Plan”). The 2015 Plan provides for the grant of incentive stock options, nonqualified stock options, stock appreciation rights, restricted stock, restricted stock units, performance shares, performance share units and other share-based awards and is intended as a successor plan to the 2007 Stock Plan since no further grants will be made under the 2007 Stock Plan. 4,200,000 shares of common stock are authorized to be used for 2015 Plan purposes. Options under the 2015 Plan may be granted at exercise prices determined by the Board of Directors, provided that the exercise prices shall not be less than the higher of the par value or 100% of the fair market value of j2 Global’s common stock subject to the option on the date the option is granted. At December 31, 2016 , 2015 and 2014 , options to purchase 353,258 , 457,792 and 618,437 shares of common stock were exercisable under and outside of the 2015 Plan, the 2007 Plan and the 1997 Plan combined, at weighted average exercise prices of $26.10 , $24.78 and $23.77 , respectively. Stock options generally expire after 10 years and vest over a 5 -year period. All stock option grants are approved by “outside directors” within the meaning of Internal Revenue Code Section 162(m). Stock Options Stock option activity for the years ended December 31, 2016 , 2015 and 2014 is summarized as follows: Number of Shares Weighted-Average Exercise Price Weighted-Average Remaining Contractual Life (In Years) Aggregate Intrinsic Value Options outstanding at January 1, 2014 1,175,657 $ 21.08 Granted — — Exercised (433,008 ) 15.70 Canceled (17,000 ) 29.85 Options outstanding at December 31, 2014 725,649 $ 24.29 Granted 62,000 67.35 Exercised (221,221 ) 22.41 Canceled — — Options outstanding at December 31, 2015 566,428 $ 29.74 Granted — — Exercised (142,870 ) 26.04 Canceled (9,700 ) 26.92 Options outstanding at December 31, 2016 413,858 $ 31.09 3.8 $20,988,138 Exercisable at December 31, 2016 353,258 $ 26.10 3.1 $19,676,668 Vested and expected to vest at December 31, 2016 402,809 $ 30.14 3.7 $20,809,814 For the years ended December 31, 2016, 2015 and 2014, j2 Global granted zero , 62,000 and zero options, respectively, to purchase shares of common stock pursuant to the 2015 Plan. These stock options vest 20% per year and expire 10 years from the date of grant. The per share weighted-average grant-date fair values of stock options granted during the period ended December 31, 2015 was $15.22 . There were no stock options granted during the years 2016 and 2014. The total intrinsic values of options exercised during the years ended December 31, 2016 , 2015 and 2014 was $5.6 million , $10.5 million and $14.6 million , respectively. The total fair value of options vested during the years ended December 31, 2016 , 2015 and 2014 was $0.6 million , $0.7 million and $2.3 million , respectively. Cash received from options exercised under all share-based payment arrangements for the years ended December 31, 2016 , 2015 and 2014 was $3.6 million , $5.0 million and $6.6 million , respectively. The actual tax benefit realized for the tax deductions from option exercises under the share-based payment arrangements totaled $1.9 million , $3.7 million and $5.2 million , respectively, for the years ended December 31, 2016 , 2015 and 2014 . The following table summarizes information concerning outstanding and exercisable options as of December 31, 2016 : Options Outstanding Exercisable Options Range of Exercise Prices Number Outstanding December 31, 2016 Weighted Average Remaining Contractual Life Weighted Average Exercise Price Number Exercisable December 31, 2016 Weighted Average Exercise Price $17.19 24,000 2.18 years $ 17.19 24,000 $ 17.19 20.91 45,558 1.34 years 20.91 45,558 20.91 21.67 53,376 2.35 years 21.67 53,376 21.67 21.88 347 0.95 years 21.88 347 21.88 22.92 84,092 3.35 years 22.92 84,092 22.92 24.61 - 28.52 29,200 3.18 years 26.67 23,200 26.79 29.34 75,585 4.36 years 29.34 75,585 29.34 29.53 - 31.07 21,700 5.05 years 30.06 16,700 30.22 32.45 18,000 0.59 years 32.45 18,000 32.45 67.35 62,000 8.35 years 67.35 12,400 67.35 $17.19 - $67.35 413,858 3.82 years $ 31.09 353,258 $ 26.10 As discussed in Note 11 - Stockholders’ Equity, the Company provided holders of j2 Series B Stock an exchange right in which j2 Series B Stock may be exchanged for j2 common stock during specified exchange periods. The Company determined that such exchange right represents a grant under the 2007 Plan for the year ended December 31, 2014, and accordingly, reduced the awards available under the 2007 Plan. At December 31, 2016 , there were 3,738,654 additional shares underlying options, shares of restricted stock and other share-based awards available for grant under the 2015 Plan, and no additional shares are available for grant under or outside of the 2007 and 1997 Plans. The Company recognized $0.4 million , $0.7 million and $1.2 million of compensation expense related to stock options for the years ended December 31, 2016, 2015 and 2014, respectively. As of December 31, 2016 , there was $0.7 million of total unrecognized compensation expense related to nonvested share-based compensation options granted under the 2015 Plan, 2007 Plan and the 1997 Plan. That expense is expected to be recognized ratably over a weighted average period of 2.80 years (i.e., the remaining requisite service period). Fair Value Disclosure j2 Global uses the Black-Scholes option pricing model to calculate the fair value of each option grant. The expected volatility is based on historical volatility of the Company’s common stock. The Company estimates the expected term based upon the historical exercise behavior of our employees. The risk-free interest rate is based on U.S. Treasury zero-coupon issues with a term equal to the expected term of the option assumed at the date of grant. The Company uses an annualized dividend yield based upon the per share dividends declared by its Board of Directors. Estimated forfeiture rates were 12.7% , 14.1% and 12.3% as of December 31, 2016 , 2015 and 2014 , respectively. The weighted-average fair values of stock options granted have been estimated utilizing the following assumptions: Years Ended December 31, 2016 2015 2014 Risk-free interest rate —% 1.61% —% Expected term (in years) 0.0 5.2 0.0 Dividend yield —% 1.8% —% Expected volatility —% 28.12% —% Weighted average volatility —% 28.12% —% Restricted Stock and Restricted Stock Units j2 Global has awarded restricted stock and restricted stock units to its Board of Directors and senior staff pursuant to the 1997 Plan, the 2007 Plan, and the 2015 Plan. Compensation expense resulting from restricted stock and restricted unit grants is measured at fair value on the date of grant and is recognized as share-based compensation expense over the applicable vesting period. Beginning in fiscal year 2012 vesting periods are approximately one year for awards to members of the Company’s Board of Directors and five years for senior staff. The Company granted 317,914 , 252,940 and 265,601 shares of restricted stock and restricted units during the years ended December 31, 2016 , 2015 and 2014 , respectively, and recognized $13.2 million , $11.0 million and $7.7 million , respectively of related compensation expense. As of December 31, 2016 , the Company had unrecognized share-based compensation cost of $37.9 million associated with these awards. This cost is expected to be recognized over a weighted-average period of 3.3 years for awards and 3.2 years for units. The total fair value of restricted stock and restricted stock units vested during the years ended December 31, 2016 , 2015 and 2014 was $8.0 million , $6.4 million and $8.5 million , respectively. The actual tax benefit realized for the tax deductions from the vesting of restricted stock awards and units totaled $3.5 million , $3.8 million and $5.0 million , respectively, for the years ended December 31, 2016 , 2015 and 2014 . In accordance with ASC 718, share-based compensation is recognized on dividends paid related to nonvested restricted stock not expected to vest, which amounted to approximately $0.1 million , $0.1 million and $0.1 million for the years ended December 31, 2016 , 2015 and 2014, respectively. Restricted Stock - Awards with Market Conditions In May 2016, certain key employees were granted market-based restricted stock awards. The market-based awards have vesting conditions that are based on specified stock price targets of the Company’s common stock. Market conditions were factored into the grant date fair value using a Monte Carlo valuation model, which utilized multiple input variables to determine the probability of the Company achieving the specified stock price targets with a 20-day lookback (trading days). Stock-based compensation expense related to an award with a market condition will be recognized over the requisite service period using the graded-vesting method regardless of whether the market condition is satisfied, provided that the requisite service period has been completed. During the year ended December 31, 2016 and 2015 , the Company awarded 106,780 and zero market-based restricted stock awards, respectively. The per share weighted average grant-date fair values of the market-based restricted stock awards granted during the year ended December 31, 2016 were $44.67 . The weighted-average fair values of market-based restricted stock awards granted have been estimated utilizing the following assumptions: December 31, 2016 Underlying stock price at valuation date $ 63.73 Expected volatility 29.8 % Risk-free interest rate 1.51 % Restricted stock award activity for the years ended December 31, 2016 , 2015 and 2014 is set forth below: Shares Weighted-Average Grant-Date Fair Value Nonvested at January 1, 2014 1,178,371 $ 17.86 Granted 226,864 45.66 Vested (546,115 ) 15.63 Canceled (45,070 ) 35.55 Nonvested at December 31, 2014 814,050 $ 26.57 Granted 234,540 68.11 Vested (254,871 ) 25.16 Canceled (88,915 ) 40.97 Nonvested at December 31, 2015 704,804 $ 39.08 Granted 296,414 41.27 Vested (255,503 ) 31.27 Canceled (40,700 ) 63.95 Nonvested at December 31, 2016 705,015 $ 41.40 Restricted stock unit activity for the years ended December 31, 2016 , 2015 and 2014 is set forth below: Number of Weighted-Average Aggregate Outstanding at January 1, 2014 109,725 Granted 38,737 Vested (19,598 ) Canceled (25,940 ) Outstanding at December 31, 2014 102,924 Granted 18,400 Vested (23,221 ) Canceled (41,858 ) Outstanding at December 31, 2015 56,245 Granted 21,500 Vested (14,595 ) Canceled (11,200 ) Outstanding at December 31, 2016 51,950 1.8 $ 4,249,510 Vested and expected to vest at December 31, 2016 41,163 1.6 $ 3,367,103 Employee Stock Purchase Plan In May of 2001, j2 Global established the j2 Global, Inc. 2001 Employee Stock Purchase Plan, as amended (the “Purchase Plan”), which provides for the issuance of a maximum of 2,000,000 shares of common stock. Under the Purchase Plan, eligible employees can have up to 15% of their earnings withheld, up to certain maximums, to be used to purchase shares of j2 Global’s common stock at certain plan-defined dates. The price of the common stock purchased under the Purchase Plan for the offering periods is equal to 95% of the fair market value of the common stock at the end of the offering period. During 2016 , 2015 and 2014 , 3,918 , 4,020 and 5,735 shares, respectively were purchased under the Purchase Plan at price ranging from $68.88 to $60.34 per share during 2016. As of December 31, 2016 , 1,626,526 shares were available under the Purchase Plan for future issuance.

Condensed Consolidating Financials [Abstract]
Condensed Consolidating Financials	Consolidating Financial Statements In connection with the June 2014 Convertible Note issuance, j2 Global, Inc. entered into a supplemental indenture related to the Senior Notes, pursuant to which it fully and unconditionally guaranteed, on an unsecured basis, the full and punctual payment of the Senior Notes issued by its wholly owned subsidiary, j2 Cloud Services. j2 Cloud Services is subject to restrictions on dividends in its existing indenture with respect to the Senior Notes. While substantially all of the Company’s assets (other than the net cash proceeds from the issuance of the Convertible Notes) are owned directly or indirectly by j2 Cloud Services, those contractual provisions did not, as of June 30, 2014, meaningfully restrict the ability of j2 Cloud Services to pay dividends to j2 Global, Inc. The following condensed consolidating financial statements present, in separate columns, financial information for (i) j2 Global, Inc. (the “Parent”) on a parent-only basis, (ii) j2 Cloud Services, LLC, (iii) the non-guarantor subsidiaries on a combined basis, (iv) the eliminations and reclassifications necessary to arrive at the information for the Company on a consolidated basis, and (v) the Company on a consolidated basis. The condensed consolidating financial statements are presented in accordance with the equity method. Under this method, the investments in subsidiaries are recorded at cost and adjusted for the Company’s share of subsidiaries’ cumulative results of operations, capital contributions, distributions and other equity changes. Intercompany charges (income) between the Parent and subsidiaries are recognized in the condensed consolidating financial statements during the period incurred and the settlement of intercompany balances is reflected in the condensed consolidating statement of cash flows based on the nature of the underlying transactions. Consolidating adjustments include consolidating and eliminating entries for investments in subsidiaries, intercompany activity and balances. j2 GLOBAL, INC.

Accounting Policies [Abstract]
Consolidation, Policy [Policy Text Block]	(a) Principles of Consolidation The accompanying consolidated financial statements include the accounts of j2 Global and its direct and indirect wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. Reorganization On June 10, 2014, j2 Global, Inc., a Delaware corporation, completed a corporate reorganization (the “Holding Company Reorganization”) pursuant to which j2 Global, Inc. (the “Predecessor”), merged with j2 Merger Sub, Inc., a Delaware corporation and an indirect, wholly owned subsidiary of the Predecessor, and changed its name to “j2 Cloud Services, Inc.” The Predecessor surviving the merger became a direct, wholly owned subsidiary of a new public holding company, j2 Global Holdings, Inc. (the “Holding Company”), which in connection with the merger changed its name to j2 Global, Inc. At the effective time of the merger and in connection with the Holding Company Reorganization, all outstanding shares of common stock and preferred stock of the Predecessor were automatically converted into identical shares of common stock or preferred stock, as applicable, of the Holding Company on a one-for-one basis, and the Predecessor’s existing stockholders and other equity holders became stockholders and equity holders, as applicable, of the Holding Company in the same amounts and percentages as they were in the Predecessor prior to the Holding Company Reorganization. On August 10, 2016, j2 Cloud Services, Inc., a wholly owned subsidiary of the Company and a Delaware corporation, converted into a Delaware limited liability company which continues as j2 Cloud Services, LLC. On August 12, 2016, all of the equity interests in Ziff Davis, LLC, a Delaware limited liability company, and all of the equity interests in Advanced Messaging Technologies, Inc., a Delaware corporation, held by j2 Cloud Services, LLC, a Delaware limited liability company, were distributed to j2 Global, the parent company of j2 Cloud Services, LLC.
Use Of Estimates	(b) Use of Estimates The preparation of consolidated financial statements in accordance with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements, including judgments about investment classifications, and the reported amounts of net revenue and expenses during the reporting period. We believe that our most significant estimates are those related to valuation and impairment of marketable securities, valuation of assets acquired and liabilities assumed in connection with business combinations, long-lived and intangible asset impairment, contingent consideration, income taxes and contingencies and allowance for doubtful accounts. On an ongoing basis, management evaluates its estimates based on historical experience and on various other factors that the Company believes to be reasonable under the circumstances. Actual results could materially differ from those estimates.
Allowances For Doubtful Accounts	(c) Allowances for Doubtful Accounts j2 Global reserves for receivables it may not be able to collect. These reserves for the Company’s Business Cloud Services segment are typically driven by the volume of credit card declines and past due invoices and are based on historical experience as well as an evaluation of current market conditions. These reserves for the Company’s Digital Media segment are typically driven by past due invoices based on historical experience. On an ongoing basis, management evaluates the adequacy of these reserves.
Revenue Recognition	(d) Revenue Recognition Business Cloud Services The Company’s Business Cloud Services revenues substantially consist of monthly recurring subscription and usage-based fees, which are primarily paid in advance by credit card. In accordance with GAAP, the Company recognizes revenue when persuasive evidence of an arrangement exists, services have been provided, the sales price is fixed and determinable and collection is probable. The Company defers the portions of monthly, quarterly, semi-annually and annually recurring subscription and usage-based fees collected in advance and recognizes them in the period earned. Additionally, the Company defers and recognizes subscriber activation fees and related direct incremental costs over a subscriber’s estimated useful life. Along with our numerous proprietary Business Cloud Services solutions, the Company also generates revenues by reselling various third party solutions, primarily through our email security and online backup lines of business. These third party solutions, along with our proprietary products, allow the Company to offer customers a variety of solutions to better meet their needs. The Company determines whether reseller revenue should be reported on a gross or net basis by assessing whether the Company is acting as the principal or an agent in the transaction. If the Company is acting as the principal in a transaction, the Company reports revenue on a gross basis. If the Company is acting as an agent in a transaction, the Company reports revenue on a net basis. In determining whether the Company acts as the principal or an agent, the Company follows the accounting guidance for principal-agent considerations and the Company places the most weight on three factors: whether or not the Company (i) is the primary obligor in the arrangement, (ii) has latitude in determining pricing and (iii) bears credit risk. The Company records revenue on a gross basis with respect to reseller revenue as the Company is the primary obligator in the arrangement, has latitude in determining pricing and bears all credit risk associated with our reseller program partners. j2 Global’s Business Cloud Services also include patent license revenues generated under license agreements that provide for the payment of contractually determined fully paid-up or royalty-bearing license fees to j2 Global in exchange for the grant of non-exclusive, retroactive and future licenses to our intellectual property, including patented technology. Patent revenues may also consist of revenues generated from the sale of patents. Patent license revenues are recognized when earned over the term of the license agreements. With regard to fully paid-up license arrangements, the Company recognizes as revenue in the period the license agreement is executed the portion of the payment attributable to past use of the intellectual property and amortizes the remaining portion of such payments on a straight-line basis, or pro-rata revenue basis, as appropriate over the life of the licensed patent(s). With regard to royalty-bearing license arrangements, the Company recognizes revenues of license fees earned during the applicable period. With regard to patent sales, the Company recognizes as revenue in the period of the sale the amount of the purchase price over the carrying value of the patent(s) sold. The Business Cloud Services business also generates revenues by licensing certain technology to third parties. These licensing revenues are recognized when earned in accordance with the terms of the underlying agreement. Generally, revenue is recognized as the third party uses the licensed technology over the period. Digital Media The Company’s Digital Media revenues primarily consist of revenues generated from the sale of advertising campaigns that are targeted to the Company’s proprietary websites and to those websites operated by third parties that are part of the Digital Media business’s advertising network. Revenues for these advertising campaigns are recognized as earned, either when an ad is placed for viewing by a visitor to the appropriate web page or when the visitor “clicks through” on the ad, depending upon the terms with the individual advertiser. Revenues for Digital Media business-to-business operations consist of lead-generation campaigns for IT vendors and are recognized as earned when the Company delivers the qualified leads to the customer. j2 Global also generates Digital Media revenues through the license of certain assets to clients, for the clients’ use in their own promotional materials or otherwise. Such assets may include logos, editorial reviews, or other copyrighted material. Revenues under such license agreements are recognized when the assets are delivered to the client. Also, Digital Media revenues are generated through the license of certain speed testing technology which is recognized when delivered to the client through providing data services primarily to Internet Service Providers (“ISPs”) and wireless carriers which is recognized as earned over the term of the access period. The Digital Media business also generates other types of revenues, including business listing fees, subscriptions to online publications, and from other sources. Such other revenues are recognized as earned. The Company determines whether Digital Media revenue should be reported on a gross or net basis by assessing whether the Company is acting as the principal or an agent in the transaction. If the Company is acting as the principal in a transaction, the Company reports revenue on a gross basis. If the Company is acting as an agent in a transaction, the Company reports revenue on a net basis. In determining whether the Company acts as the principal or an agent, the Company follows the accounting guidance for principal-agent considerations and the Company places the most weight on three factors: whether or not the Company (i) is the primary obligor in the arrangement, (ii) has latitude in determining pricing and (iii) bears credit risk. The Company records revenue on a gross basis with respect to revenue generated (i) by the Company serving online display and video advertising across its owned-and-operated web properties, on third party sites or on unaffiliated advertising networks, (ii) through the Company’s lead-generation business and (iii) through the Company’s Digital Media licensing program. The Company records revenue on a net basis with respect to revenue paid to the Company by certain third-party advertising networks who serve online display and video advertising across the Company’s owned-and-operated web properties and certain third party sites.
Fair Value Measurements	(e) Fair Value Measurements j2 Global complies with the provisions of Financial Accounting Standards Board (“FASB”) Accounting Standard Codification (“ASC”) Topic No. 820, Fair Value Measurements and Disclosures (“ASC 820”), in measuring fair value and in disclosing fair value measurements. ASC 820 provides a framework for measuring fair value and expands the disclosures required for fair value measurements of financial and non-financial assets and liabilities. As of December 31, 2016 , the carrying value of cash and cash equivalents, short-term investments, accounts receivable, interest receivable, accounts payable, accrued expenses, interest payable, customer deposits and long-term debt are reflected in the financial statements at cost. With the exception of long-term debt, cost approximates fair value due to the short-term nature of such instruments. The fair value of the Company’s outstanding debt was determined using the quoted market prices of debt instruments with similar terms and maturities, if available. As of the same dates, the carrying value of other long-term liabilities approximated fair value as the related interest rates approximate rates currently available to j2 Global.
Cash and Cash Equivalents, Policy [Policy Text Block]	(f) Cash and Cash Equivalents j2 Global considers cash equivalents to be only those investments that are highly liquid, readily convertible to cash and with maturities of three months or less at the purchase date.
Investment, Policy [Policy Text Block]	(g) Investments j2 Global accounts for its investments in debt and equity securities in accordance with FASB ASC Topic No. 320, Investments - Debt and Equity Securities (“ASC 320”). Debt investments are typically comprised of corporate and governmental debt securities. Equity securities recorded as available-for-sale represent strategic equity investments. j2 Global determines the appropriate classification of its investments at the time of acquisition and evaluates such determination at each balance sheet date. Held-to-maturity securities are those investments which the Company has the ability and intent to hold until maturity and are recorded at amortized cost. Available-for-sale securities are those investments j2 Global does not intend to hold to maturity and can be sold. Available-for-sale securities are carried at fair value with unrealized gains and losses included in other comprehensive income. Trading securities are carried at fair value, with unrealized gains and losses included in investment income. Securities are accounted for on a specific identification basis, average cost method or other method, as appropriate.
Debt, Policy [Policy Text Block]	(h) Debt Issuance Costs and Debt Discount j2 Global capitalizes costs incurred with borrowing and issuance of debt securities and records debt issuance costs and discounts as a reduction to the debt amount. These costs and discounts are amortized and included in interest expense over the life of the borrowing or term of the credit facility using the effective interest method.
Derivatives, Policy [Policy Text Block]	(i) Derivative Instruments j2 Global currently holds an embedded derivative instrument related to contingent interest in connection with its 3.25% Convertible Notes issued on June 10, 2014. This embedded derivative instrument is carried at fair value with changes recorded to interest expense (see Note 5 - Fair Value Measurements).
Concentration Of Credit Risk	(j) Concentration of Credit Risk All of the Company’s cash, cash equivalents and marketable securities are invested at major financial institutions primarily within the United States, United Kingdom and Ireland. These institutions are required to invest the Company’s cash in accordance with the Company’s investment policy with the principal objectives being preservation of capital, fulfillment of liquidity needs and above market returns commensurate with preservation of capital. The Company’s investment policy also requires that investments in marketable securities be in only highly rated instruments, with limitations on investing in securities of any single issuer. However, these investments are not insured against the possibility of a total or near complete loss of earnings or principal and are inherently subject to the credit risk related to the continued credit worthiness of the underlying issuer and general credit market risks. At December 31, 2016 , the Company’s cash and cash equivalents were maintained in accounts that are insured up to the limit determined by the applicable governmental agency. The Company’s deposits held in qualifying financial institutions in Ireland are fully insured through March 28, 2018 to the extent on deposit prior to March 28, 2013. With respect to the Company’s deposits with financial institutions in other jurisdictions, the insured amount held in other institutions is immaterial in comparison to the total amount of the Company’s cash and cash equivalents held by these institutions which is not insured. These institutions are primarily in the United States and United Kingdom, however, the Company has accounts within several other countries including Australia, Austria, China, France, Germany, Italy, Japan, New Zealand and the Netherlands.
Foreign Currency Transactions and Translations Policy [Policy Text Block]	(k) Foreign Currency Some of j2 Global’s foreign subsidiaries use the local currency of their respective countries as their functional currency. Assets and liabilities are translated at exchange rates prevailing at the balance sheet dates. Revenues, costs and expenses are translated into U.S. Dollars at average exchange rates for the period. Gains and losses resulting from translation are recorded as a component of accumulated other comprehensive income (loss). Net translation gain/(loss) was $(23.1) million , $(15.1) million and $(14.7) million for the years ended December 31, 2016 , 2015 and 2014 , respectively. Realized gains and losses from foreign currency transactions are recognized within other expense (income), net. Net transaction gain/(loss) was $(0.7) million , $(0.1) million and $(0.1) million for the years ended December 31, 2016, 2015 and 2014, respectively.
Property, Plant and Equipment, Policy [Policy Text Block]	(l) Property and Equipment Property and equipment are stated at cost. Equipment under capital leases is stated at the present value of the minimum lease payments. Depreciation is calculated using the straight-line method over the estimated useful lives of the assets. The estimated useful lives of property and equipment range from 1 to 10 years. Fixtures, which are comprised primarily of leasehold improvements and equipment under capital leases, are amortized on a straight-line basis over their estimated useful lives or for leasehold improvements, the related lease term, if less. The Company has capitalized certain internal use software and website development costs which are included in property and equipment. The estimated useful life of costs capitalized is evaluated for each specific project and ranges from 1 to 5 years.
Impairment or Disposal of Long-Lived Assets, Policy [Policy Text Block]	(m) Long-Lived Assets j2 Global accounts for long-lived assets, which include property and equipment and identifiable intangible assets with finite useful lives (subject to amortization), in accordance with the provisions of FASB ASC Topic No. 360, Property, Plant, and Equipment (“ASC 360”), which requires that long-lived assets be reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability is measured by comparing the carrying amount of an asset to the expected undiscounted future net cash flows generated by the asset. If it is determined that the asset may not be recoverable, and if the carrying amount of an asset exceeds its estimated fair value, an impairment charge is recognized to the extent of the difference. j2 Global assessed whether events or changes in circumstances have occurred that potentially indicate the carrying amount of long-lived assets may not be recoverable. No impairment was recorded in fiscal year 2016, 2015 or 2014.
Goodwill and Intangible Assets, Policy [Policy Text Block]	(n) Goodwill and Intangible Assets Goodwill represents the excess of the purchase price over the fair value of the net tangible and identifiable intangible assets acquired in a business combination. Intangible assets resulting from the acquisitions of entities accounted for using the purchase method of accounting are recorded at the estimated fair value of the assets acquired. Identifiable intangible assets are comprised of purchased customer relationships, trademarks and trade names, developed technologies and other intangible assets. Intangible assets subject to amortization are amortized over the period of estimated economic benefit ranging from 1 to 20 years. In accordance with FASB ASC Topic No. 350, Intangibles - Goodwill and Other (“ASC 350”), goodwill and other intangible assets with indefinite lives are not amortized but tested annually for impairment or more frequently if j2 Global believes indicators of impairment exist. In connection with the annual impairment test for goodwill, the Company has the option to perform a qualitative assessment in determining whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If the Company determines that it was more likely than not that the fair value of the reporting unit is less than its carrying amount, then it performs the impairment test upon goodwill. The impairment test involves a two-step process. The first step involves comparing the fair values of the applicable reporting units with their aggregate carrying values, including goodwill. The Company generally determines the fair value of its reporting units using the income approach methodology of valuation. If the carrying value of a reporting unit exceeds the reporting unit’s fair value, j2 Global performs the second step of the test to determine the amount of impairment loss. The second step involves measuring the impairment by comparing the implied fair values of the affected reporting unit’s goodwill and intangible assets with the respective carrying values. In connection with the annual impairment test for indefinite-lived intangible assets, we have the option to perform a qualitative assessment in determining whether it is more likely than not that the fair value is less than its carrying amount, then we perform the impairment test upon indefinite-lived intangible assets. The impairment testing for indefinite-lived intangible assets consists of comparing the carrying values to the fair values and an impairment loss is recorded if the carrying value exceeds the fair value. j2 Global completed the required impairment review at the end of 2016, 2015 and 2014 and concluded that there were no impairments. Consequently, no impairment charges were recorded.
Business Combinations Policy [Policy Text Block]	(o) Contingent Consideration j2 Global measures the contingent earn-out liabilities in connection with acquisitions at fair value on a recurring basis using significant unobservable inputs classified within Level 3 of the fair value hierarchy (see Note 5 - Fair Value Measurements). The Company may use various valuation techniques depending on the terms and conditions of the contingent consideration including a Monte-Carlo simulation. This simulation uses a probability distribution for each significant input to produce hundreds or thousands of possible outcomes and the results are analyzed to determine probabilities of different outcomes occurring. Significant increases or decreases to these inputs in isolation would result in a significantly higher or lower liability with a higher liability capped by the contractual maximum of the contingent earn-out obligation. Ultimately, the liability will be equivalent to the amount paid, and the difference between the fair value estimate and amount paid will be recorded in earnings. The amount paid that is less than or equal to the liability on the acquisition date is reflected as cash used in financing activities in our consolidated statements of cash flows. Any amount paid in excess of the liability on the acquisition date is reflected as cash used in operating activities. j2 Global reviews and re-assess the estimated fair value of contingent consideration on a quarterly basis, and the updated fair value could differ materially from the initial estimates. Changes in the estimated fair value of our contingent earn-out liabilities related to the time component of the present value calculation are reported in interest expense. Adjustments to the estimated fair value related to changes in all other unobservable inputs are reported in operating income.
Income Taxes	(p) Income Taxes j2 Global’s income is subject to taxation in both the U.S. and numerous foreign jurisdictions. Significant judgment is required in evaluating the Company’s tax positions and determining its provision for income taxes. During the ordinary course of business, there are many transactions and calculations for which the ultimate tax determination is uncertain. j2 Global establishes reserves for tax-related uncertainties based on estimates of whether, and the extent to which, additional taxes will be due. These reserves for tax contingencies are established when the Company believes that certain positions might be challenged despite the Company’s belief that its tax return positions are fully supportable. j2 Global adjusts these reserves in light of changing facts and circumstances, such as the outcome of a tax audit or lapse of a statute of limitations. The provision for income taxes includes the impact of reserve provisions and changes to reserves that are considered appropriate. j2 Global accounts for income taxes in accordance with FASB ASC Topic No. 740, Income Taxes (“ASC 740”), which requires that deferred tax assets and liabilities be recognized using enacted tax rates for the effect of temporary differences between the book and tax basis of recorded assets and liabilities. ASC 740 also requires that deferred tax assets be reduced by a valuation allowance if it is more likely than not that some or all of the net deferred tax assets will not be realized. The valuation allowance is reviewed quarterly based upon the facts and circumstances known at the time. In assessing this valuation allowance, j2 Global reviews historical and future expected operating results and other factors, including its recent cumulative earnings experience, expectations of future taxable income by taxing jurisdiction and the carryforward periods available for tax reporting purposes, to determine whether it is more likely than not that deferred tax assets are realizable. ASC 740 provides guidance on the minimum threshold that an uncertain income tax benefit is required to meet before it can be recognized in the financial statements and applies to all income tax positions taken by a company. ASC 740 contains a two-step approach to recognizing and measuring uncertain income tax positions. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon settlement. If it is not more likely than not that the benefit will be sustained on its technical merits, no benefit will be recorded. Uncertain income tax positions that relate only to timing of when an item is included on a tax return are considered to have met the recognition threshold. j2 Global recognized accrued interest and penalties related to uncertain income tax positions in income tax expense on its consolidated statement of income.
Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]	(q) Share-Based Compensation j2 Global accounts for share-based awards in accordance with the provisions of FASB ASC Topic No. 718, Compensation - Stock Compensation (“ASC 718”). Accordingly, j2 Global measures share-based compensation expense at the grant date, based on the fair value of the award, and recognizes the expense over the employee’s requisite service period using the straight-line method. The measurement of share-based compensation expense is based on several criteria, including but not limited to the valuation model used and associated input factors, such as expected term of the award, stock price volatility, risk free interest rate, dividend rate and award cancellation rate. These inputs are subjective and are determined using management’s judgment. If differences arise between the assumptions used in determining share-based compensation expense and the actual factors, which become known over time, j2 Global may change the input factors used in determining future share-based compensation expense. Any such changes could materially impact the Company’s results of operations in the period in which the changes are made and in periods thereafter. The Company estimates the expected term based upon the historical exercise behavior of our employees. j2 Global accounts for option grants to non-employees in accordance with FASB ASC Topic No. 505, Equity, whereby the fair value of such options is determined using the Black-Scholes option pricing model at the earlier of the date at which the non-employee’s performance is complete or a performance commitment is reached.
Earnings Per Share, Policy [Policy Text Block]	(r) Earnings Per Common Share EPS is calculated pursuant to the two-class method as defined in ASC Topic No. 260, Earnings per Share (“ASC 260”), which specifies that all outstanding unvested share-based payment awards that contain rights to nonforfeitable dividends or dividend equivalents are considered participating securities and should be included in the computation of EPS pursuant to the two-class method. Basic EPS is calculated by dividing net distributed and undistributed earnings allocated to common shareholders, excluding participating securities, by the weighted-average number of common shares outstanding. The Company’s participating securities consist of its unvested share-based payment awards that contain rights to nonforfeitable dividends or dividend equivalents. Diluted EPS includes the determinants of basic EPS and, in addition, reflects the impact of other potentially dilutive shares outstanding during the period. The dilutive effect of participating securities is calculated under the more dilutive of either the treasury method or the two-class method.
Research and Development Expense, Policy [Policy Text Block]	(s) Research, Development and Engineering Research, development and engineering costs are expensed as incurred. Costs for software development incurred subsequent to establishing technological feasibility, in the form of a working model, are capitalized and amortized over their estimated useful lives.
Segment Reporting, Policy [Policy Text Block]	(t) Segment Reporting FASB ASC Topic No. 280, Segment Reporting (“ASC 280”), establishes standards for the way that public business enterprises report information about operating segments in their annual consolidated financial statements and requires that those enterprises report selected information about operating segments in interim financial reports. ASC 280 also establishes standards for related disclosures about products and services, geographic areas and major customers. The Company operates as two segments: (1) Business Cloud Services and (2) Digital Media.
Advertising Costs, Policy [Policy Text Block]	(u) Advertising Costs Advertising costs are expensed as incurred. Advertising costs for the years ended December 31, 2016, 2015 and 2014 was $96.8 million , $63.5 million and $60.5 million , respectively.
Revenue Recognition, Excise and Sales Taxes	(v) Sales Taxes The Company may collect sales taxes from certain customers which are remitted to governmental authorities as required and are excluded from revenues.
New Accounting Pronouncements, Policy [Policy Text Block]	(w) Recent Accounting Pronouncements In May 2014, the FASB Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers, as a new Topic, (ASC) Topic 606. The new revenue recognition standard provides a five-step analysis of transactions to determine when and how revenue is recognized. The core principle is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In August 2015, the FASB issued ASU No. 2015-14, Revenue from Contracts with Customers: Deferral of the Effective Date, which deferred the effective date of the new revenue standard for periods beginning after December 15, 2016 to December 15, 2017, with early adoption permitted but not earlier than the original effective date. This ASU must be applied retrospectively to each period presented or as a cumulative-effect adjustment as of the date of adoption. The Company is considering the alternatives of adoption of this ASU, has substantially completed a review of the likely impact to the existing portfolio of customer contracts entered into prior to adoption and will continue to evaluate the effect of adopting this guidance upon the Company’s results of operations, cash flows and financial position. Currently, the Company does not expect the adoption of this ASU to have a material impact on our financial statements except that there are significant additional reporting requirements under the new standard. In November 2014, the FASB issued ASU No. 2014-16, Derivatives and Hedging (Topic 815): Determining Whether the Host Contract in a Hybrid Financial Instrument Issued in the Form of a Share is More Akin to Debt or to Equity, which clarifies how current guidance should be interpreted in evaluating the economic characteristics and risks of a host contract in a hybrid financial instrument that is issued in the form of a share. Specifically, the amendments clarify that an entity should consider all relevant terms and features, including the embedded derivative feature being evaluated for bifurcation, in evaluating the nature of the host contract. The assessment of the substance of the relevant terms and features should incorporate a consideration of: (1) the characteristics of the terms and features themselves; (2) the circumstances under which the hybrid financial instrument was issued or acquired; and (3) the potential outcomes of the hybrid financial instrument, as well as the likelihood of those potential outcomes. The amendments in this ASU apply to all entities that are issuers of, or investors in, hybrid financial instruments that are issued in the form of a share. The amendments in this ASU are effective for annual reporting periods beginning after December 15, 2015, including interim periods within that reporting period. The Company has adopted this guidance in the first quarter 2016 and has determined that there is no impact on our financial statements and related disclosures. In April 2015, the FASB issued ASU No. 2015-03, Interest - Imputation Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs. The amendments in this ASU provide guidance that requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The amendments in this ASU are effective for financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. The Company adopted this guidance during the first quarter 2016 on a retrospective basis which resulted in a reclassification of 2015 debt issuance costs of $9.1 million from Other assets to Long-term debt in our Consolidated Balance Sheets. The adoption of this standard did not have a material impact on our financial statements and related disclosures. In November 2015, the FASB issued ASU No. 2015-17, Balance Sheet Classification of Deferred Taxes. This ASU requires that deferred tax liabilities and assets be classified as noncurrent in a classified statement of financial position. The Company adopted this ASU during the first quarter 2016 on a prospective basis. Adoption has resulted in a reclassification of our current deferred tax assets and deferred tax liabilities to the non-current deferred tax assets and deferred tax liabilities in our Consolidated Balance Sheets. No prior periods were retrospectively adjusted. In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. The amendments in this ASU modify how entities measure equity investments and present changes in the fair value of financial liabilities. Under the new guidance, entities will have to measure equity investments that do not result in consolidation and are not accounted under the equity method at fair value and recognize any changes in fair value in net income unless the investments qualify for the new practicality exception. A practicality exception will apply to those equity investments that do not have a readily determinable fair value and do not qualify for the practical expedient to estimate fair value under ASC 820, Fair Value Measurements, and as such these investments may be measured at cost. This ASU is effective for financial statements issued for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. The Company is currently evaluating the impact of this ASU on our financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases. This ASU establishes a right-of-use (ROU) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. This ASU is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. The Company is currently evaluating the impact of the pending adoption of this new standard on our financial statements and has yet to determine the overall impact this ASU is expected to have. The Company currently has both capital and operating leases both domestically and internationally with varying expiration dates through 2025 in the amount of $74.2 million for the period ended December 31, 2016. In March 2016, the FASB issued ASU 2016-06, Derivatives and Hedging (Topic 815). This ASU is related to the embedded derivative analysis for debt instruments with contingent call or put options. This ASU clarifies that an exercise contingency does not need to be evaluated to determine whether it relates only to interest rates or credit risk. Instead, the contingent put or call option should be evaluated for possible bifurcation as a derivative in accordance with the four-step decision sequence detailed in FASB ASC 815-15, without regard to the nature of the exercise contingency. This ASU is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2016. Early adoption is permitted. The Company is currently evaluating the impact of this ASU on our financial statements. In March 2016, the FASB issued ASU 2016-08, Revenue from Contracts with Customers (Topic 606). This ASU is related to reporting revenue gross versus net, or principal versus agent considerations. This ASU is meant to clarify the guidance in ASU 2014-09, Revenue from Contracts with Customers, as it pertains to principal versus agent considerations. Specifically, the guidance addresses how entities should identify goods and services being provided to a customer, the unit of account for a principal versus agent assessment, how to evaluate whether a good or service is controlled before being transferred to a customer, and how to assess whether an entity controls services performed by another party. This ASU has the same effective date as the new revenue standard, which is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2017. The Company is evaluating the effect and methodology of adopting this new accounting guidance upon the Company’s results of operations, cash flows and financial position. The Company is considering the alternatives of adoption of this ASU, has substantially completed a review of the likely impact to the existing portfolio of customer contracts entered into prior to adoption and will continue to evaluate the effect of adopting this guidance upon the Company’s results of operations, cash flows and financial position. Currently, the Company does not expect the adoption of this ASU to have a material impact on our financial statements except that there are significant additional reporting requirements under the new standard. In March 2016, the FASB issued ASU 2016-09, Compensation-Stock Compensation (Topic 718). This ASU is related to simplifications of employee share-based payment accounting. This pronouncement eliminates the APIC pool concept and requires that excess tax benefits and tax deficiencies be recorded in the income statement when awards are settled. The pronouncement also addresses simplifications related to statement of cash flows classification, accounting for forfeitures and minimum statutory tax withholding requirements. This ASU is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2016. Early adoption is permitted. The Company is currently evaluating the impact of this ASU on our financial statements. In April 2016, the FASB issued ASU 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing. This ASU is meant to clarify the guidance in FASB ASU 2014-09, Revenue from Contracts with Customers. Specifically, the guidance addresses an entity’s identification of its performance obligations in a contract, as well as an entity’s evaluation of the nature of its promise to grant a license of intellectual property and whether or not that revenue is recognized over time or at a point in time. This ASU has the same effective date as the new revenue standard, which is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2017. The Company is considering the alternatives of adoption of this ASU, has substantially completed a review of the likely impact to the existing portfolio of customer contracts entered into prior to adoption and will continue to evaluate the effect of adopting this guidance upon the Company’s results of operations, cash flows and financial position. Currently, the Company does not expect the adoption of this ASU to have a material impact on our financial statements except that there are significant additional reporting requirements under the new standard. In May 2016, the FASB issued ASU 2016-11, Revenue Recognition (Topic 605) and Derivatives and Hedging (Topic 815): Rescission of SEC Guidance Because of Accounting Standards Updates 2014-09 and 2014-16 Pursuant to Staff Announcements at the March 3, 2016 EITF Meeting. This ASU rescinds SEC paragraphs pursuant to two SEC Staff Announcements at the March 3, 2016 Emerging Issues Task Force (EITF) meeting. Specifically, registrants should not rely on the following SEC Staff Observer comments upon adoption of Topic 606: (1) Revenue and Expense Recognition for Freight Services in Process, which is codified in paragraph 605-20-S99-2; (2) Accounting for Shipping and Handling Fees and Costs, which is codified in paragraph 605-45-S99-1; (3) Accounting for Consideration Given by a Vendor to a Customer (including Reseller of the Vendor’s Products), which is codified in paragraph 605-50-S99-1; and (4) Accounting for Gas-Balancing Arrangements (i.e., use of the “entitlements method”), which is codified in paragraph 932-10-S99-5. This ASU becomes effective upon adoption of ASU 2014-09, which is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2017. The Company is considering the alternatives of adoption of this ASU, has substantially completed a review of the likely impact to the existing portfolio of customer contracts entered into prior to adoption and will continue to evaluate the effect of adopting this guidance upon the Company’s results of operations, cash flows and financial position. Currently, the Company does not expect the adoption of this ASU to have a material impact on our financial statements. In May 2016, the FASB issued ASU 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients. This ASU does not change the core principle of the guidance in Topic 606. Instead, the amendments provide clarifying guidance in a few narrow areas and add some practical expedients to the guidance. This ASU has the same effective date as the new revenue standard, which is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2017. The Company is currently evaluating the impact of the pending adoption of this new standard on our financial statements. The Company is considering the alternatives of adoption of this ASU, has substantially completed a review of the likely impact to the existing portfolio of customer contracts entered into prior to adoption and will continue to evaluate the effect of adopting this guidance upon the Company’s results of operations, cash flows and financial position. Currently, the Company does not expect the adoption of this ASU to have a material impact on our financial statements except that there are significant additional reporting requirements under the new standard. In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The amendments in this ASU replace the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. This ASU is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2019. The Company has not adopted this ASU and currently has determined there to be no impact of this ASU on our financial statements and related disclosures. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. The new guidance is intended to reduce diversity in practice in how transactions are classified in the statement of cash flows. This ASU is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2017. Early adoption is permitted. The Company is currently evaluating the impact of this ASU on our financial statements. In October 2016, the FASB issued ASU 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other than Inventory. The amendments in this ASU reduce the complexity in the accounting standards by allowing the recognition of current and deferred income taxes for an intra-entity asset transfer, other than inventory, when the transfer occurs. Historically, the income tax consequence was not recognized until the asset was sold to an outside party. This ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017. Early adoption is permitted. The Company is currently evaluating the impact of this ASU on our financial statements. In November 2016, the FASB issued 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash - a consensus of the FASB Emerging Issues Task Force. The amendments in this ASU require restricted cash and restricted cash equivalents to be classified in the Statement of Cash Flows as cash and cash equivalents. The guidance will be applied on a retrospective basis beginning with the earliest period presented. The amendments in this ASU are effective for annual and interim periods beginning after December 15, 2017. Early adoption is permitted. The adoption of this standard is not expected to have a material impact on our financial statements. In December 2016, the FASB issued 2016-19, Technical Corrections and Improvements. The amendments in this ASU represent changes to clarify, correct errors, or make minor improvements to the Codification. The Update includes simplification and minor improvements to topics on insurance and troubled debt restructuring that result in numerous editorial changes to the Codification. Most of the amendments in the Update do not require transition guidance and are effective upon issuance of the ASU. The remaining six amendments in this ASU have various adoption dates. The Company adopted this ASU during the fourth quarter 2016 on a prospective basis. Since this update is intended to clarify the Codification, correct unintended application of guidance, or make minor improvements to the Codification that are not expected to have a significant effect on current accounting practice, the adoption of this standard did not have a material impact on our financial statements. In December 2016, the FASB issued 2016-20, Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers. The amendments in this ASU represent changes to clarify the Codification or to correct unintended application of guidance. Areas for correction or improvement include: Loan Guarantee Fees, Contract Costs - Impairment Testing, Contract Costs - Interaction of Impairment Testing with Guidance in Other Topics, Provisions for Losses on Construction-Type and Production Type Contracts, Scope of Topic 606, Disclosure of Remaining Performance Obligations, Disclosure of Prior-Period Performance Obligations, Contract Modification Example, Contract Asset versus Receivable, Refund Liability, Advertising Costs, Fixed-Odd Wagering Contracts in the Casino Industry and Cost Capitalization for Advisors to Private Funds and Public Funds. This ASU has the same effective date as the new revenue standard, which is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2017. The adoption of this standard is not expected to have a material impact on our financial statements except that there are significant additional reporting requirements under the new standard. In January 2017, the FASB issued 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business. The amendments in this ASU provide a robust framework to use in determining when a set of assets and activities is a business. This ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017. Early adoption is permitted and the standard should be applied prospectively. The Company is currently evaluating the impact of this ASU on our financial statements and related disclosures. In January 2017, the FASB issued 2017-03, Accounting Changes and Error Corrections (Topic 250) and Investments - Equity Method and Joint Ventures (Topic 323): Amendments to SEC Paragraphs Pursuant to Staff Announcements at the September 22, 2016 and November 17, 2016 EITF Meetings. The amendments in this ASU add language to the SEC Staff Guidance in relation to ASU 2014-09, Revenue from Contracts with Customers (Topic 606), ASU 2016-02, Leases (Topic 842), and ASU 2016-13, Financial Instruments - Credit Losses (Topic 326). This ASU provides the SEC Staff view that a registrant should consider additional quantitative and qualitative disclosures related to the previously mentioned ASUs in connection with the status and impact of their adoption. The Company adopted this ASU during the current quarter 2016. Since this update intended to add disclosures related to certain ASUs, the adoption of this standard did not have a material impact on our financial statements. In January 2017, the FASB issued 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. The amendments in this ASU simplify the subsequent measurement of goodwill by eliminating Step 2 from the goodwill impairment test and eliminating the requirement for a reporting unit with a zero or negative carrying amount to perform a qualitative assessment. Instead, under this pronouncement, an entity would perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount and would recognize an impairment change for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized is not to exceed the total amount of goodwill allocated to that reporting unit. In addition, income tax effects will be considered, if applicable. This ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted. The Company is currently evaluating the impact of this ASU on our financial statements and related disclosures.
