Accounting Policies [Abstract]
Use Of Estimates	Use of Estimates The preparation of consolidated financial statements in accordance with 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. The Company believes that its most significant estimates are those related to revenue recognition, valuation and impairment of investments, its assessment of ownership interests as variable interest entities and the related determination of consolidation, share-based compensation expense, fair value of assets acquired and liabilities assumed in connection with business combinations, long-lived and intangible asset impairment, contingent consideration, income taxes and contingencies and allowances 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. Additionally, the full impact of the COVID-19 pandemic is unknown and cannot be reasonably estimated. However, the Company has made appropriate accounting estimates based on the facts and circumstances available as of the reporting date. To the extent there are differences between these estimates and the actual results, our condensed consolidated financial statements could be materially affected.
Allowances For Doubtful Accounts	Allowances for Doubtful AccountsJ2 Global reserves for receivables it may not be able to collect. The reserves for the Company’s Cloud Services business 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. The reserves for the Company’s Digital Media business are typically driven by past due invoices based on historical experience. On an ongoing basis, management evaluates the adequacy of these reserves.
Revenue [Policy Text Block]	Revenue Recognition J2 Global recognizes revenue when the Company satisfies its obligation by transferring control of the goods or services to its customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods or services (see Note 3 - Revenues). Principal vs. Agent The Company determines whether 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 under Topic 606 for principal-agent considerations and assesses: (i) if another party is involved in providing goods or services to the customer and (ii) whether the Company controls the specified goods or services prior to transferring control to the customer. Sales Taxes The Company has made an accounting policy election to exclude from the measurement of the transaction price all taxes assessed by a governmental authority that are (i) both imposed on and concurrent with a specific revenue-producing transaction and (ii) collected by the Company from a customer.
Investment, Policy [Policy Text Block]	Investments The Company accounts for its investments in debt securities in accordance with ASC Topic No. 320, Investments - Debt Securities (“ASC 320”). Debt investments are typically comprised of corporate debt securities. J2 Global determines the appropriate classification of its investments at the time of acquisition and evaluates such determination at each balance sheet date. Trading securities are those investments that the Company intends to sell within a few hours or days and are carried at fair value, with unrealized gains and losses included in investment income. Available-for-sale debt 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. 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. All debt securities are accounted for on a specific identification basis. The Company accounts for its investments in equity securities in accordance with ASC Topic No. 321, Investments - Equity Securities (“ASC 321”) which requires the accounting for equity investments (other than those accounted for using the equity method of accounting) generally be measured at fair value for equity securities with readily determinable fair values. For equity securities without a readily determinable fair value that are not accounted for by the equity method, the Company measures the equity security using cost, less impairment, if any, and plus or minus observable price changes arising from orderly transactions in the same or similar investment from the same issuer. Any unrealized gains or losses will be reported in current earnings (see Note 5 - Investments). Variable Interest Entities (“VIE”) A VIE requires consolidation by the entity’s primary beneficiary. The Company evaluates its investments in entities in which it is involved to determine if the entity is a VIE and if so, whether it holds a variable interest and is the primary beneficiary. The Company has determined that it holds a variable interest in its investment as a limited partner in the OCV Fund I, LP (“OCV Fund”, “OCV” or the “Fund”). In determining whether the Company is deemed to be the primary beneficiary of the VIE, both of the following characteristics must be present: a) the Company has the power to direct the activities of the VIE that most significantly impacts the VIEs economic performance (the power criterion); and b) the Company has the obligation to absorb losses of the VIE, or the right to receive benefits of the VIE, that could potentially be significant to the VIE (the economic criterion). The Company has concluded that, as a limited partner, although the obligations to absorb losses or benefit from the gains is not insignificant, the Company does not have “power” over OCV because it does not have the ability to direct the significant decisions which impact the economics of OCV. J2 believes that the OCV general partner, as a single decision maker, holds the ability to make the decisions about the activities that most significantly impact the OCV Fund’s economic performance. As a result, the Company has concluded that it will not consolidate OCV, as it is not the primary beneficiary of the OCV Fund, and will account for this investment under the equity-method of accounting. See Note 5, “Investments”. OCV qualifies as an investment company under ASC 946 - Financial Services, Investment Companies (“ASC 946”). Under ASC Topic 323, Investments - Equity Method and Joint Ventures, an investor that holds investments that qualify for specialized industry accounting for investment companies in accordance with ASC 946 should record its share of the earnings or losses, realized or unrealized, as reported by its equity method investees in the Condensed Consolidated Statements of Operations. The Company recognizes its equity in the net earnings or losses relating to the investment in OCV on a one-quarter lag due to the timing and availability of financial information from OCV. If the Company becomes aware of a significant decline in value that is other-than-temporary, the loss will be recorded in the period in which the Company identifies the decline.
Impairment or Disposal of Long-Lived Assets, Policy	Impairment or Disposal of 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 in the first quarter of 2020. The Company classifies its long-lived assets to be sold as held for sale in the period (i) it has approved and committed to a plan to sell the asset, (ii) the asset is available for immediate sale in its present condition, (iii) an active program to locate a buyer and other actions required to sell the asset have been initiated, (iv) the sale of the asset is probable, (v) the asset is being actively marketed for sale at a price that is reasonable in relation to its current fair value, and (vi) it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn. The Company initially measures a long-lived asset that is classified as held for sale at the lower of its carrying value or fair value less any costs to sell. Any loss resulting from this measurement is recognized in the period in which the held for sale criteria are met. Conversely, gains are not recognized on the sale of a long-lived asset until the date of sale. Upon designation as an asset held for sale, the Company stops recording depreciation expense on the asset. The Company assesses the fair value of a long-lived asset less any costs to sell at each reporting period and until the asset is no longer classified as held for sale.
Goodwill and Intangible Assets, Policy	Business Combinations and Valuation of Goodwill and Intangible Assets J2 Global applies the acquisition method of accounting for business combinations in accordance with GAAP, which requires the Company to make use of estimates and judgments to allocate the purchase price paid for acquisitions to the fair value of the assets, including identifiable intangible assets, and liabilities acquired. Such estimates may be based on significant unobservable inputs and assumptions such as, but not limited to, revenue growth rates, gross margins, customer attrition rates, royalty rates, discount rates and terminal growth rate assumptions. J2 Global uses established valuation techniques and may engage reputable valuation specialists to assist with the valuations. Management’s estimates of fair value are based upon assumptions believed to be reasonable, but which are inherently uncertain and unpredictable and, as a result, actual results may differ from estimates. Fair values are subject to refinement for up to one year after the closing date of an acquisition as information relative to closing date fair values becomes available. Upon the conclusion of the measurement period, any subsequent adjustments are recorded to earnings. 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 acquisition 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 is 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 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, an impairment loss is recognized for the difference. The Company performed a qualitative assessment which determined that one business unit required further consideration and necessitated a quantitative assessment as of March 31, 2020. The qualitative assessment took into consideration macroeconomic, industry and market conditions, overall financial performance and any other relevant company-specific events. The quantitative assessment did not indicate that the fair value was lower than the business unit’s carrying value, accordingly, no impairment was recorded. J2 Global concluded that there were no impairments in the first quarter of 2020. In addition, the COVID-19 pandemic could have an adverse impact on the Company’s consolidated financial results in the second quarter of 2020, and possibly longer. As of March 31, 2020, there were no indications that the carrying value of goodwill and other intangible assets may not be recoverable. However, a prolonged adverse impact of the COVID-19 pandemic on the Company’s consolidated financial results may require an impairment charge related to one or more of these assets in a future period.
Business Combinations Policy [Policy Text Block]	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 6 - 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 the 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 its 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-assesses the estimated fair value of contingent consideration on a quarterly basis, and the updated fair value could be materially different from the initial estimates or prior quarterly amounts. Changes in the estimated fair value of its contingent earn-out liabilities are reported in operating income. Adjustments to the estimated fair value related to changes in all other unobservable inputs are reported in operating income.
Income Tax, Policy	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 statements of operations. In addition, on March 27, 2020, the “Coronavirus Aid, Relief and Economic Security (CARES) Act” was enacted into law and provides for changes to various tax laws that impact businesses. The CARES Act, among other things, includes provisions relating to refundable payroll tax credits, deferment of employer side social security payments, net operating loss carryback periods, alternative minimum tax credit refunds, modifications to the net interest deduction limitations, increased limitations on qualified charitable contributions and technical corrections to tax depreciation methods for qualified improvement property. The CARES Act also appropriated funds for the Small Business Administration (“SBA”) Paycheck Protection Program loans that are forgivable in certain situations to promote continued employment, as well as Economic Injury Disaster Loans to provide liquidity to small businesses harmed by COVID-19. The Company did not seek to borrow any funds under the program. We do not believe these provisions have a significant impact to our current and deferred income tax balances. The Company anticipates it will benefit from the technical correction to tax depreciation related to qualified improvement property and has elected to defer income tax payments and employer side social security payments where eligible. As further guidance is released regarding the CARES Act, we will record adjustments to our tax balances, as necessary.
Share-based Payment Arrangement	Share-Based Compensation J2 Global accounts for share-based awards to employees and non-employees 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 its employees.
Comparability of Prior Year Financial Data	Reclassifications Certain prior year reported amounts have been reclassified to conform to the 2020 presentation.

Use of Estimates

The preparation of consolidated financial statements in accordance with 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. The Company believes that its most significant estimates are those related to revenue recognition, valuation and impairment of investments, its assessment of ownership interests as variable interest entities and the related determination of consolidation, share-based compensation expense, fair value of assets acquired and liabilities assumed in connection with business combinations, long-lived and intangible asset impairment, contingent consideration, income taxes and contingencies and allowances 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.

Additionally, the full impact of the COVID-19 pandemic is unknown and cannot be reasonably estimated. However, the Company has made appropriate accounting estimates based on the facts and circumstances available as of the reporting date. To the extent there are differences between these estimates and the actual results, our condensed consolidated financial statements could be materially affected.

Allowances For Doubtful Accounts

Allowances for Doubtful AccountsJ2 Global reserves for receivables it may not be able to collect. The reserves for the Company’s Cloud Services business 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. The reserves for the Company’s Digital Media business are typically driven by past due invoices based on historical experience. On an ongoing basis, management evaluates the adequacy of these reserves.

Revenue [Policy Text Block]

Revenue Recognition

J2 Global recognizes revenue when the Company satisfies its obligation by transferring control of the goods or services to its customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods or services (see Note 3 - Revenues).

Principal vs. Agent

The Company determines whether 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 under Topic 606 for principal-agent considerations and assesses: (i) if another party is involved in providing goods or services to the customer and (ii) whether the Company controls the specified goods or services prior to transferring control to the customer.

Sales Taxes

The Company has made an accounting policy election to exclude from the measurement of the transaction price all taxes assessed by a governmental authority that are (i) both imposed on and concurrent with a specific revenue-producing transaction and (ii) collected by the Company from a customer.

Investment, Policy [Policy Text Block]

Investments

The Company accounts for its investments in debt securities in accordance with ASC Topic No. 320, Investments - Debt Securities (“ASC 320”). Debt investments are typically comprised of corporate debt securities. J2 Global determines the appropriate classification of its investments at the time of acquisition and evaluates such determination at each balance sheet date. Trading securities are those investments that the Company intends to sell within a few hours or days and are carried at fair value, with unrealized gains and losses included in investment income. Available-for-sale debt 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. 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. All debt securities are accounted for on a specific identification basis.

The Company accounts for its investments in equity securities in accordance with ASC Topic No. 321, Investments - Equity Securities (“ASC 321”) which requires the accounting for equity investments (other than those accounted for using the equity method of accounting) generally be measured at fair value for equity securities with readily determinable fair values. For equity securities without a readily determinable fair value that are not accounted for by the equity method, the Company measures the equity security using cost, less impairment, if any, and plus or minus observable price changes arising from orderly transactions in the same or similar investment from the same issuer. Any unrealized gains or losses will be reported in current earnings (see Note 5 - Investments).

Variable Interest Entities (“VIE”)

A VIE requires consolidation by the entity’s primary beneficiary. The Company evaluates its investments in entities in which it is involved to determine if the entity is a VIE and if so, whether it holds a variable interest and is the primary beneficiary. The Company has determined that it holds a variable interest in its investment as a limited partner in the OCV Fund I, LP (“OCV Fund”, “OCV” or the “Fund”). In determining whether the Company is deemed to be the primary beneficiary of the VIE, both of the following characteristics must be present:

a) the Company has the power to direct the activities of the VIE that most significantly impacts the VIEs economic performance (the power criterion); and

b) the Company has the obligation to absorb losses of the VIE, or the right to receive benefits of the VIE, that could potentially be significant to the VIE (the economic criterion).

The Company has concluded that, as a limited partner, although the obligations to absorb losses or benefit from the gains is not insignificant, the Company does not have “power” over OCV because it does not have the ability to direct the significant decisions which impact the economics of OCV. J2 believes that the OCV general partner, as a single decision maker, holds the ability to make the decisions about the activities that most significantly impact the OCV Fund’s economic performance. As a result, the Company has concluded that it will not consolidate OCV, as it is not the primary beneficiary of the OCV Fund, and will account for this investment under the equity-method of accounting. See Note 5, “Investments”.

OCV qualifies as an investment company under ASC 946 - Financial Services, Investment Companies (“ASC 946”). Under ASC Topic 323, Investments - Equity Method and Joint Ventures, an investor that holds investments that qualify for specialized industry accounting for investment companies in accordance with ASC 946 should record its share of the earnings or losses, realized or unrealized, as reported by its equity method investees in the Condensed Consolidated Statements of Operations.

The Company recognizes its equity in the net earnings or losses relating to the investment in OCV on a one-quarter lag due to the timing and availability of financial information from OCV. If the Company becomes aware of a significant decline in value that is other-than-temporary, the loss will be recorded in the period in which the Company identifies the decline.

Impairment or Disposal of Long-Lived Assets, Policy

Impairment or Disposal of 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 in the first quarter of 2020.

The Company classifies its long-lived assets to be sold as held for sale in the period (i) it has approved and committed to a plan to sell the asset, (ii) the asset is available for immediate sale in its present condition, (iii) an active program to locate a buyer and other actions required to sell the asset have been initiated, (iv) the sale of the asset is probable, (v) the asset is being actively marketed for sale at a price that is reasonable in relation to its current fair value, and (vi) it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn. The Company initially measures a long-lived asset that is classified as held for sale at the lower of its carrying value or fair value less any costs to sell. Any loss resulting from this measurement is recognized in the period in which the held for sale criteria are met. Conversely, gains are not recognized on the sale of a long-lived asset until the date of sale. Upon designation as an asset held for sale, the Company stops recording depreciation expense on the asset. The Company assesses the fair value of a long-lived asset less any costs to sell at each reporting period and until the asset is no longer classified as held for sale.

Goodwill and Intangible Assets, Policy

Business Combinations and Valuation of Goodwill and Intangible Assets

J2 Global applies the acquisition method of accounting for business combinations in accordance with GAAP, which requires the Company to make use of estimates and judgments to allocate the purchase price paid for acquisitions to the fair value of the assets, including identifiable intangible assets, and liabilities acquired. Such estimates may be based on significant unobservable inputs and assumptions such as, but not limited to, revenue growth rates, gross margins, customer attrition rates, royalty rates, discount rates and terminal growth rate assumptions. J2 Global uses established valuation techniques and may engage reputable valuation specialists to assist with the valuations. Management’s estimates of fair value are based upon assumptions believed to be reasonable, but which are inherently uncertain and unpredictable and, as a result, actual results may differ from estimates. Fair values are subject to refinement for up to one year after the closing date of an acquisition as information relative to closing date fair values becomes available. Upon the conclusion of the measurement period, any subsequent adjustments are recorded to earnings.

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 acquisition 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 is 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 Company performed a qualitative assessment which determined that one business unit required further consideration and necessitated a quantitative assessment as of March 31, 2020. The qualitative assessment took into consideration macroeconomic, industry and market conditions, overall financial performance and any other relevant company-specific events. The quantitative assessment did not indicate that the fair value was lower than the business unit’s carrying value, accordingly, no impairment was recorded. J2 Global concluded that there were no impairments in the first quarter of 2020.

In addition, the COVID-19 pandemic could have an adverse impact on the Company’s consolidated financial results in the second quarter of 2020, and possibly longer. As of March 31, 2020, there were no indications that the carrying value of goodwill and other intangible assets may not be recoverable. However, a prolonged adverse impact of the COVID-19 pandemic on the Company’s consolidated financial results may require an impairment charge related to one or more of these assets in a future period.

Business Combinations Policy [Policy Text Block]

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 6 - 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 the 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 its 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-assesses the estimated fair value of contingent consideration on a quarterly basis, and the updated fair value could be materially different from the initial estimates or prior quarterly amounts. Changes in the estimated

fair value of its contingent earn-out liabilities are reported in operating income. Adjustments to the estimated fair value related to changes in all other unobservable inputs are reported in operating income.

Income Tax, Policy

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 statements of operations.

In addition, on March 27, 2020, the “Coronavirus Aid, Relief and Economic Security (CARES) Act” was enacted into law and provides for changes to various tax laws that impact businesses. The CARES Act, among other things, includes provisions relating to refundable payroll tax credits, deferment of employer side social security payments, net operating loss carryback periods, alternative minimum tax credit refunds, modifications to the net interest deduction limitations, increased limitations on qualified charitable contributions and technical corrections to tax depreciation methods for qualified improvement property.

The CARES Act also appropriated funds for the Small Business Administration (“SBA”) Paycheck Protection Program loans that are forgivable in certain situations to promote continued employment, as well as Economic Injury Disaster Loans to provide liquidity to small businesses harmed by COVID-19. The Company did not seek to borrow any funds under the program.

We do not believe these provisions have a significant impact to our current and deferred income tax balances. The Company anticipates it will benefit from the technical correction to tax depreciation related to qualified improvement property and has elected to defer income tax payments and employer side social security payments where eligible. As further guidance is released regarding the CARES Act, we will record adjustments to our tax balances, as necessary.

Share-based Payment Arrangement

Share-Based Compensation

J2 Global accounts for share-based awards to employees and non-employees 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 its employees.
