Accounting Policies [Abstract]
Significant Accounting Policies	2. Significant Accounting Policies The Transactions were accounted for as a reverse merger in accordance with accounting principles generally accepted in the United States of America (“GAAP”). This determination was primarily based on Cision comprising the ongoing operations of the combined entity, Cision’s senior management comprising the majority of the senior management of the combined company, and the prior shareholders of Cision having a majority of the voting power of the combined entity. Accordingly, the Transactions have been treated equivalent to Cision issuing stock for the net monetary assets of Capitol, accompanied by a recapitalization. The net assets of Capitol at the merger date have been stated at historical cost, with no goodwill or other intangible assets recorded. Operations prior to the Transactions in these financial statements are those of Cision. As a result, these financial statements represent the continuation of Cision Ltd. and the historical shareholders’ equity and earnings per share calculations of Cision prior to the Transactions have been retrospectively adjusted for the equivalent number of shares received by Cision’s Owner, where applicable, pursuant to the Transactions. The accumulated deficit of Cision has been carried forward after the Transactions. Cision Ltd., the parent company, has no independent operating activity or third-party assets and liabilities. Prior to the June 29, 2017 Transactions, earnings per share was calculated using the two-class method. On June 29, 2017, all outstanding classes of equity of Cision were contributed in exchange for 82,075,873 120,512,402 28,369,644 The preparation of financial statements in conformity with GAAP requires management to make certain estimates and assumptions. On an on-going basis, the Company evaluates its estimates, including, but not limited to, those related to the allowance for doubtful accounts, software development costs, useful lives of property, equipment and internal use software, intangible assets and goodwill, contingent liabilities, and fair value of equity-based awards and income taxes. The Company bases its estimates on various assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities as well as the reported amounts of revenues and expenses during the period. Actual results could differ from these estimates. The Company considers all highly liquid investments with original maturity dates of three months or less at the time of purchase to be cash equivalents. For all years reported the Company did not carry any investments with original maturity dates of longer than three months. The Company measures certain financial assets and liabilities at fair value pursuant to a fair value hierarchy based on inputs to valuation techniques that are used to measure fair value that are either observable or unobservable. Observable inputs reflect assumptions market participants would use in pricing an asset or liability based on market data obtained from independent sources while unobservable inputs reflect a reporting entity’s pricing based upon its own market assumptions. The fair value hierarchy consists of the following three levels: Level 1 Inputs are quoted prices in active markets for identical assets or liabilities. Level 2 Inputs are quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable and market-corroborated inputs which are derived principally from or corroborated by observable market data. Level 3 Inputs are derived from valuation techniques in which one or more significant inputs or value drivers are unobservable. Other than long-term debt and Convertible Preferred Equity Certificates due to Cision Owner at December 31, 2016, the Company had no financial assets or liabilities that were other than Level 1 at December 31, 2017 and 201 Estimates are used to determine the amount of the allowance for doubtful accounts necessary to reduce accounts receivable to the estimated net realizable value. These estimates are made by analyzing the status of significant past-due receivables and by establishing provisions for estimated losses by analyzing current and historical bad debt trends. Actual collection experience has not varied significantly from prior estimates. The allowance for doubtful accounts at December 31, 2017 and 2016 was $ 5.3 2.6 The Company incurs software development costs related to its internal use software. Qualifying costs incurred during the application development stage are capitalized. These costs primarily consist of internal labor and third-party development costs and are amortized using the straight-line method over the estimated useful life of the software, which is generally two years. All other research and development costs are expensed as incurred. Costs to maintain and update the information database are expensed within cost of revenues as these expenses are incurred. For the years ended December 31, 2017, 2016 and 2015, the Company recorded amortization expense related to internal use software of $ 12.4 12.6 6.9 Property, equipment and purchased software are stated at cost. Depreciation is computed using the straight-line method over the estimated useful lives of the assets as follows: three to five years for software and computer and office equipment and five to seven years for furniture and fixtures. Assets acquired under capital leases and leasehold improvements are amortized using the straight-line method over the shorter of the estimated useful lives of the assets or the terms of the leases. Amortization of assets acquired under capital leases is included in depreciation and amortization expense. Repairs and maintenance costs are charged to expense as incurred. When assets are retired or otherwise disposed of, the asset and related accumulated depreciation are eliminated from the accounts and any resulting gain or loss is recorded in the results of operations. Long-lived assets include property, equipment and software and intangible assets with finite lives. Intangible assets consist of customer relationships, trade names and purchased technology acquired in business combinations. Intangible assets are amortized using the straight-line method, which approximates the pattern of usage of the economic benefit of the asset, over their estimated useful lives ranging from two to twelve years. Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be fully recoverable. If an impairment indicator is present, the Company evaluates recoverability by a comparison of the carrying amount of the assets to future undiscounted net cash flows expected to be generated by the assets. If the assets are impaired, the impairment recognized is measured by the amount by which the carrying amount exceeds the estimated fair value of the assets. There were no significant impairment charges for long-lived assets for the years ended December 31, 2017, 2016 or 2015. The Company regularly revisits its estimate of useful economic lives of long lived assets and makes adjustments to those lives where appropriate. The Company has completed a number of acquisitions of businesses during the years ended December 31, 2017, 2016 and 2015 that have resulted in the recording of goodwill and identifiable definite-lived intangible assets. The Company recognizes all of the assets acquired and liabilities assumed at their fair values on the acquisition date. The Company uses significant estimates and assumptions, including fair value estimates, as of the acquisition date using the income and cost approaches (or a combination thereof). Fair values are determined based on Level 3 inputs, including estimated future cash flows, discount rates, royalty rates, growth rates, sales projections, customer retention rates and terminal values, all of which require significant management judgment. The Company refines these estimates that are provisional, as necessary, during the measurement period. The measurement period is the period after the acquisition date, not to exceed one year, in which new information may be gathered about facts and circumstances that existed as of the acquisition date to adjust the provisional amounts recognized. Adjustments to assets and liabilities within the measurement period are recorded with a corresponding offset to goodwill. All other adjustments, including those after the conclusion of the measurement period, are recorded to the consolidated statements of net loss and, to date, have been immaterial. The Company amortizes costs to obtain financing over the term of the underlying obligation using either the effective interest method or the straight-line method, as appropriate. Debt discounts and deferred financing costs are netted from the carrying value of the debt and amortized over the term of the debt using the effective interest method. Deferred financing fees related to the Company’s revolving debt facilities are included within other assets in the consolidated balance sheets. The amortization of deferred financing costs and debt discounts is included in interest expense in the accompanying consolidated statements of net loss and comprehensive loss. Goodwill represents the excess of the cost of an acquired entity over the net fair value of the identifiable assets acquired and liabilities assumed. Goodwill is not amortized, but rather is assessed for impairment at least annually. The Company performs its annual impairment assessment on October 1, or whenever events or circumstances indicate impairment may have occurred. On October 1, 2017, 2016 and 2015, the Company performed its annual goodwill impairment assessment based on the fair value of each of the Company’s reporting units. When assessing goodwill for impairment, the Company uses an income approach based on discounted cash flows to determine the fair value of its reporting unit. The Company’s cash flow assumptions consider historical and forecasted revenue, operating costs and other relevant factors which are consistent with the plans used to manage the Company’s operations. The result of the most recent annual goodwill impairment test performed on October 1, 2017 indicated that the estimated fair value of each reporting unit was at least 40% in excess of its carrying value. Based on the results of the Company’s goodwill impairment tests, there was no indication of impairment as of October 1, 2017, 2016 The reporting currency for all periods presented is the U.S. dollar. The functional currency for the Company’s foreign operating subsidiaries is their local currency. The functional currency of the Company and substantially all of its non operating subsidiaries is the US dollar. The financial statements of these subsidiaries are translated into U.S. dollars using exchange rates in effect at each balance sheet date for assets and liabilities and average exchange rates during the period for revenues and expenses. The resulting translation adjustments are included in accumulated other comprehensive income (loss), a separate component of stockholders’ deficit. Gains or losses, whether realized or unrealized due to transactions in foreign currencies and the remeasurement of certain intercompany balances, are included in the consolidated statements of net loss and total comprehensive loss. Employees of CNW Group Ltd. (“CNW”) participate in a defined benefit pension plan whereby pension expense is determined based on a number of actuarial assumptions, which are reviewed on an annual basis. The defined benefit plan has been closed to new participants since 2006. The employees and accompanying pension plan were inherited with the acquisition of PRN Group (“PR Newswire”) on June 16, 2016. The purchase price of PR Newswire was allocated to the assets and obligations of the pension plan based on fair value at the acquisition date. These actuarial assumptions include discount rate, expected rate of return on plan assets, rate of salary increases and other factors. The unfunded status of the plan is recognized as a long-term liability in the consolidated balance sheets at December 31, 2017 and 2016, which is also the measurement date for the defined benefit pension plan for the CNW employees. The Company’s investment in an unconsolidated affiliate over which the Company has significant influence is accounted for under the equity method of accounting. The investment was acquired with the PR Newswire acquisition and the purchase price of PR Newswire was allocated to the investee based on its fair value as of the acquisition date. The Company records its share of the undistributed income or loss from this investment, which, to date, have been immaterial. The Company regularly reviews the carrying value of this investment for impairment using such information as forecasts, business plans and available financial statements of the investee. Since the PR Newswire acquisition, no impairment losses have been recognized. At December 31, 2017 and 2016, the investment in unconsolidated affiliate is $ 4.2 5.6 Comprehensive income (loss) includes the Company’s net income (loss) and foreign currency translation adjustments. There are no other material components of comprehensive loss for the years ended December 31, 2017, 2016 and 2015. The Company derives its revenues from subscription arrangements and related professional services in connection with the Company’s cloud-based software and services offerings. The Company also derives revenues from news distribution services on both a subscription basis and separately from non-subscription arrangements. The Company recognizes revenue when there is persuasive evidence of an arrangement, the service has been provided to the customer, the collection of the fee is probable and the amount of the fee to be paid by the customer is fixed or determinable. The Company’s separate units of accounting consist of its subscription services, transactional services and professional services. The subscription services include access to the Company’s cloud-based software, hosting services, content and content updates and customer support. The Company’s subscription agreements are typically one to three years in length and are non-cancelable, though customers have the right to terminate their agreements for cause if the Company materially breaches its obligations under the agreement. Subscription agreements do not provide customers the right to take possession of the software at any time. The Company does not charge customers an up-front fee for use of the technology. Implementation activities are insignificant and are not subject to a separate fee. In certain cases, the Company charges annual membership fees to customers which are recognized ratably over the one-year membership period. The Company also distributes individual news releases to thousands of distribution points on the Internet, which are then indexed by major search engines and also directly to journalists and other key constituents. Dependent on the nature of the contract with the customer, the Company recognizes revenue on subscription basis over the term of the subscription, or on a per-transaction basis when the press releases are made available to the public. Professional services include broadcast and webcast production. For these services, revenue is recognized when the specific performance is completed and customer acceptance received. Sales and other taxes collected from customers to be remitted to government authorities are excluded from revenues. Deferred revenue consists of payments received from or billings to customers in advance of revenue recognition. Deferred revenue to be recognized in the succeeding twelve-month period is included in current deferred revenue with the remaining amounts included in noncurrent deferred revenue. Invoices issued in advance of the fulfillment of a deliverable or the start of the customers’ subscription term are typically not significant. Sales commissions relate to the sale of subscription, transaction, and professional services agreements, and are expensed as incurred. The Company expenses advertising costs as incurred. Advertising costs for the years ended December 31, 2017, 2016 and 2015 were approximately $ 5.9 7.0 8.9 The Company recognizes equity-based CPECs were held by Cision Owner and were presented as liabilities in the consolidated balance sheet at December 31, 2016. The CPEC’s were redeemable at any time by the Company and matured 49 The Company has determined that its Chief Executive Officer is the Chief Operating Decision Maker. The Company’s Chief Executive Officer reviews financial information presented on both a consolidated basis and on a geographic regional basis. Since its inception, the Company has completed several significant acquisitions and has expended significant efforts in integrating these acquisitions into a single commercial software solution, available to all customers in all geographies. As a result of the long-term qualitative and quantitative similar economic characteristics exhibited by the sale of a single product suite in all the Company’s regions, the Company has determined that its operating segments meet the criteria to be aggregated into one reportable segment. Prior to the June 29, 2017 Transactions, net loss per share was calculated using the two-class method. On June 29, 2017, all outstanding classes of equity of Cision were contributed in exchange for 82,075,873 120,512,402 Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash and cash equivalents, investments and accounts receivable. The Company generally maintains its cash and cash equivalents with various nationally recognized financial institutions. Customers are granted credit on an unsecured basis. Management monitors the creditworthiness of its customers and believes that it has adequately provided for any exposure to potential credit losses. The Company provides cloud-based software, distribution services and related professional services to various customers across many industries. As of December 31, 2017 and 2016, no individual customer accounted for 10% or more of net accounts receivable. For the years ended December 31, 2017, 2016 and 2015, no individual customer accounted for 10% or more of revenue. Income taxes are determined utilizing the asset and liability method whereby deferred tax assets and liabilities are recognized for deductible temporary differences between the respective reported amounts and tax bases of assets and liabilities, as well as for operating loss and tax-credit carryforwards. Net deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized. The Company’s estimates related to liabilities for uncertain tax positions require it to make judgments regarding the sustainability of each uncertain tax position based on its technical merits. If it determines it is more likely than not that a tax position will be sustained based on its technical merits, the Company records the impact of the position in its consolidated financial statements at the largest amount that is greater than fifty percent likely of being realized upon ultimate settlement. The estimates are updated at each reporting date based on the facts, circumstances and information available. The Company is also required to assess at each reporting date whether it is reasonably possible that any significant increases or decreases to its unrecognized tax benefits will occur during the next twelve months. The Company files income tax returns in the U.S. federal jurisdictions and various state and foreign jurisdictions and is subject to U.S. federal, state, and foreign tax examinations for years ranging from 2012 to 2017. On December 22, 2017, the U.S. government enacted comprehensive tax legislation (the “Tax Act”), which contains several key tax provisions that affected the Company including a reduction of the federal corporate income tax rate to 21 As long as the Company remains an Emerging Growth Company, the Company plans to adopt new accounting standards using the effective dates available for nonpublic entities.

Accordingly, the Company recorded the following reasonable estimates of the tax impact in its consolidated financial statements as of and for the year ended December 31, 2017. a) A provisional tax expense of $ 5.5 2.1 b) A provisional tax expense of $ 6.4 The Tax Act also includes a provision to tax global intangible low-taxed income (“GILTI”) of foreign subsidiaries and a base erosion anti-abuse tax (“BEAT”) measure that taxes certain payments between a U.S. corporation and its subsidiaries. The Company will be subject to the GILTI and BEAT provisions effective beginning January 1, 2018 and is in the process of analyzing their effects, including how to account for the GILTI provision from an accounting policy standpoint. The final impact on the Company from the Tax Act’s transition tax legislation may differ from the aforementioned reasonable estimate due to the complexity of calculating and supporting with primary evidence such U.S. tax attributes as accumulated foreign earnings and profits and foreign tax paid, and other tax components involved in foreign tax credit calculations for prior years back to 1986. Such differences could be material, due to, among other things, changes in interpretations of the Tax Act, future legislative action to address questions that arise because of the Tax Act, changes in accounting standards for income taxes or related interpretations in response to the Tax Act, or any updates or changes to estimates the Company has utilized to calculate the transition tax's reasonable estimate. Pursuant to SAB 118, the Company is allowed a measurement period of up to one year after the enactment date of the Tax Act to finalize the recording of the related tax impacts. Accordingly, the Company accrued the transition tax and to the net change in deferred tax liabilities including additional valuation allowance based on the reasonable estimate guidance. The Company will continue to refine its estimate of the impact of the U.S. Tax Act and will record any resulting tax adjustments during the year ended December 31, 2018. Additionally, the Company currently believes it will use its net operating loss carryforwards to offset the transition tax, exclusive of the Canadian withholding tax. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. The Company assessed the realizability of deferred tax assets and whether it is more likely than not that a portion, or all, of the deferred tax assets can be realized. Management considers the scheduled reversal of deferred tax liabilities and tax planning strategies in making this assessment. During 2015, management concluded that a valuation allowance was required for the U.S. Federal deferred tax assets, net of federal deferred tax liabilities excluding deferred tax liabilities relating to indefinite lived intangibles. In 2016, management concluded that the valuation allowance on the U.S. federal deferred tax assets was no longer required as a result of the deferred tax liabilities established in the acquisition of PR Newswire. The reversal of such deferred tax liabilities will allow for the realizability of the U.S. deferred tax assets. In 2017, management concluded that a valuation allowance of $ 26.8 0.7 19.2 At December 31, 2017, the Company has not provided for income taxes on $ 42.0 5.5 2.1 As of December 31, 2017, the Company has net operating loss carryforwards for federal and state tax purposes of approximately $ 86.2 47.9 1.4 2.3 79.6 Certain of the Company’s federal and state NOL carryforwards are subject to annual limitations under Section 382 of Internal Revenue Code.

Significant Accounting Policies (Policies)	12 Months Ended

Accounting Policies [Abstract]
Basis of Presentation and Earnings per Share	The Transactions were accounted for as a reverse merger in accordance with accounting principles generally accepted in the United States of America (“GAAP”). This determination was primarily based on Cision comprising the ongoing operations of the combined entity, Cision’s senior management comprising the majority of the senior management of the combined company, and the prior shareholders of Cision having a majority of the voting power of the combined entity. Accordingly, the Transactions have been treated equivalent to Cision issuing stock for the net monetary assets of Capitol, accompanied by a recapitalization. The net assets of Capitol at the merger date have been stated at historical cost, with no goodwill or other intangible assets recorded. Operations prior to the Transactions in these financial statements are those of Cision. As a result, these financial statements represent the continuation of Cision Ltd. and the historical shareholders’ equity and earnings per share calculations of Cision prior to the Transactions have been retrospectively adjusted for the equivalent number of shares received by Cision’s Owner, where applicable, pursuant to the Transactions. The accumulated deficit of Cision has been carried forward after the Transactions. Cision Ltd., the parent company, has no independent operating activity or third-party assets and liabilities. Prior to the June 29, 2017 Transactions, earnings per share was calculated using the two-class method. On June 29, 2017, all outstanding classes of equity of Cision were contributed in exchange for 82,075,873 120,512,402 28,369,644
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make certain estimates and assumptions. On an on-going basis, the Company evaluates its estimates, including, but not limited to, those related to the allowance for doubtful accounts, software development costs, useful lives of property, equipment and internal use software, intangible assets and goodwill, contingent liabilities, and fair value of equity-based awards and income taxes. The Company bases its estimates on various assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities as well as the reported amounts of revenues and expenses during the period. Actual results could differ from these estimates.
Cash and Cash Equivalents and Investments	Cash and Cash Equivalents and Investments The Company considers all highly liquid investments with original maturity dates of three months or less at the time of purchase to be cash equivalents. For all years reported the Company did not carry any investments with original maturity dates of longer than three months.
Fair Value Measurement	Fair Value Measurements The Company measures certain financial assets and liabilities at fair value pursuant to a fair value hierarchy based on inputs to valuation techniques that are used to measure fair value that are either observable or unobservable. Observable inputs reflect assumptions market participants would use in pricing an asset or liability based on market data obtained from independent sources while unobservable inputs reflect a reporting entity’s pricing based upon its own market assumptions. The fair value hierarchy consists of the following three levels: Level 1 Inputs are quoted prices in active markets for identical assets or liabilities. Level 2 Inputs are quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable and market-corroborated inputs which are derived principally from or corroborated by observable market data. Level 3 Inputs are derived from valuation techniques in which one or more significant inputs or value drivers are unobservable. Other than long-term debt and Convertible Preferred Equity Certificates due to Cision Owner at December 31, 2016, the Company had no financial assets or liabilities that were other than Level 1 at December 31, 2017 and 201
Allowance for Doubtful Accounts	Allowance for Doubtful Accounts Estimates are used to determine the amount of the allowance for doubtful accounts necessary to reduce accounts receivable to the estimated net realizable value. These estimates are made by analyzing the status of significant past-due receivables and by establishing provisions for estimated losses by analyzing current and historical bad debt trends. Actual collection experience has not varied significantly from prior estimates. The allowance for doubtful accounts at December 31, 2017 and 2016 was $ 5.3 2.6
Software Development and Research and Development	Internal Use Software Development The Company incurs software development costs related to its internal use software. Qualifying costs incurred during the application development stage are capitalized. These costs primarily consist of internal labor and third-party development costs and are amortized using the straight-line method over the estimated useful life of the software, which is generally two years. All other research and development costs are expensed as incurred. Costs to maintain and update the information database are expensed within cost of revenues as these expenses are incurred. For the years ended December 31, 2017, 2016 and 2015, the Company recorded amortization expense related to internal use software of $ 12.4 12.6 6.9
Property, Equipment and Purchased Software	Property, Equipment and Purchased Software Property, equipment and purchased software are stated at cost. Depreciation is computed using the straight-line method over the estimated useful lives of the assets as follows: three to five years for software and computer and office equipment and five to seven years for furniture and fixtures. Assets acquired under capital leases and leasehold improvements are amortized using the straight-line method over the shorter of the estimated useful lives of the assets or the terms of the leases. Amortization of assets acquired under capital leases is included in depreciation and amortization expense. Repairs and maintenance costs are charged to expense as incurred. When assets are retired or otherwise disposed of, the asset and related accumulated depreciation are eliminated from the accounts and any resulting gain or loss is recorded in the results of operations.
Long-Lived Assets	Long-lived assets include property, equipment and software and intangible assets with finite lives. Intangible assets consist of customer relationships, trade names and purchased technology acquired in business combinations. Intangible assets are amortized using the straight-line method, which approximates the pattern of usage of the economic benefit of the asset, over their estimated useful lives ranging from two to twelve years. Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be fully recoverable. If an impairment indicator is present, the Company evaluates recoverability by a comparison of the carrying amount of the assets to future undiscounted net cash flows expected to be generated by the assets. If the assets are impaired, the impairment recognized is measured by the amount by which the carrying amount exceeds the estimated fair value of the assets. There were no significant impairment charges for long-lived assets for the years ended December 31, 2017, 2016 or 2015. The Company regularly revisits its estimate of useful economic lives of long lived assets and makes adjustments to those lives where appropriate.
Business Combinations	The Company has completed a number of acquisitions of businesses during the years ended December 31, 2017, 2016 and 2015 that have resulted in the recording of goodwill and identifiable definite-lived intangible assets. The Company recognizes all of the assets acquired and liabilities assumed at their fair values on the acquisition date. The Company uses significant estimates and assumptions, including fair value estimates, as of the acquisition date using the income and cost approaches (or a combination thereof). Fair values are determined based on Level 3 inputs, including estimated future cash flows, discount rates, royalty rates, growth rates, sales projections, customer retention rates and terminal values, all of which require significant management judgment. The Company refines these estimates that are provisional, as necessary, during the measurement period. The measurement period is the period after the acquisition date, not to exceed one year, in which new information may be gathered about facts and circumstances that existed as of the acquisition date to adjust the provisional amounts recognized. Adjustments to assets and liabilities within the measurement period are recorded with a corresponding offset to goodwill. All other adjustments, including those after the conclusion of the measurement period, are recorded to the consolidated statements of net loss and, to date, have been immaterial.
Deferred Financing Costs and Debt Discounts	Deferred Financing Costs and Debt Discounts The Company amortizes costs to obtain financing over the term of the underlying obligation using either the effective interest method or the straight-line method, as appropriate. Debt discounts and deferred financing costs are netted from the carrying value of the debt and amortized over the term of the debt using the effective interest method. Deferred financing fees related to the Company’s revolving debt facilities are included within other assets in the consolidated balance sheets. The amortization of deferred financing costs and debt discounts is included in interest expense in the accompanying consolidated statements of net loss and comprehensive loss.
Goodwill	Goodwill Goodwill represents the excess of the cost of an acquired entity over the net fair value of the identifiable assets acquired and liabilities assumed. Goodwill is not amortized, but rather is assessed for impairment at least annually. The Company performs its annual impairment assessment on October 1, or whenever events or circumstances indicate impairment may have occurred. On October 1, 2017, 2016 and 2015, the Company performed its annual goodwill impairment assessment based on the fair value of each of the Company’s reporting units. When assessing goodwill for impairment, the Company uses an income approach based on discounted cash flows to determine the fair value of its reporting unit. The Company’s cash flow assumptions consider historical and forecasted revenue, operating costs and other relevant factors which are consistent with the plans used to manage the Company’s operations. The result of the most recent annual goodwill impairment test performed on October 1, 2017 indicated that the estimated fair value of each reporting unit was at least 40% in excess of its carrying value. Based on the results of the Company’s goodwill impairment tests, there was no indication of impairment as of October 1, 2017, 2016
Foreign Currency and Operations	Foreign Currency The reporting currency for all periods presented is the U.S. dollar. The functional currency for the Company’s foreign operating subsidiaries is their local currency. The functional currency of the Company and substantially all of its non operating subsidiaries is the US dollar. The financial statements of these subsidiaries are translated into U.S. dollars using exchange rates in effect at each balance sheet date for assets and liabilities and average exchange rates during the period for revenues and expenses. The resulting translation adjustments are included in accumulated other comprehensive income (loss), a separate component of stockholders’ deficit. Gains or losses, whether realized or unrealized due to transactions in foreign currencies and the remeasurement of certain intercompany balances, are included in the consolidated statements of net loss and total comprehensive loss.
Defined Benefit Pension Plans	Defined Benefit Pension Plan Employees of CNW Group Ltd. (“CNW”) participate in a defined benefit pension plan whereby pension expense is determined based on a number of actuarial assumptions, which are reviewed on an annual basis. The defined benefit plan has been closed to new participants since 2006. The employees and accompanying pension plan were inherited with the acquisition of PRN Group (“PR Newswire”) on June 16, 2016. The purchase price of PR Newswire was allocated to the assets and obligations of the pension plan based on fair value at the acquisition date. These actuarial assumptions include discount rate, expected rate of return on plan assets, rate of salary increases and other factors. The unfunded status of the plan is recognized as a long-term liability in the consolidated balance sheets at December 31, 2017 and 2016, which is also the measurement date for the defined benefit pension plan for the CNW employees.
Investment in Unconsolidated Affiliate	Investment in Unconsolidated Affiliate The Company’s investment in an unconsolidated affiliate over which the Company has significant influence is accounted for under the equity method of accounting. The investment was acquired with the PR Newswire acquisition and the purchase price of PR Newswire was allocated to the investee based on its fair value as of the acquisition date. The Company records its share of the undistributed income or loss from this investment, which, to date, have been immaterial. The Company regularly reviews the carrying value of this investment for impairment using such information as forecasts, business plans and available financial statements of the investee. Since the PR Newswire acquisition, no impairment losses have been recognized. At December 31, 2017 and 2016, the investment in unconsolidated affiliate is $ 4.2 5.6
Comprehensive Income (Loss)	Comprehensive Income (Loss) Comprehensive income (loss) includes the Company’s net income (loss) and foreign currency translation adjustments. There are no other material components of comprehensive loss for the years ended December 31, 2017, 2016 and 2015.
Revenue Recognition	Revenue Recognition The Company derives its revenues from subscription arrangements and related professional services in connection with the Company’s cloud-based software and services offerings. The Company also derives revenues from news distribution services on both a subscription basis and separately from non-subscription arrangements. The Company recognizes revenue when there is persuasive evidence of an arrangement, the service has been provided to the customer, the collection of the fee is probable and the amount of the fee to be paid by the customer is fixed or determinable. The Company’s separate units of accounting consist of its subscription services, transactional services and professional services. The subscription services include access to the Company’s cloud-based software, hosting services, content and content updates and customer support. The Company’s subscription agreements are typically one to three years in length and are non-cancelable, though customers have the right to terminate their agreements for cause if the Company materially breaches its obligations under the agreement. Subscription agreements do not provide customers the right to take possession of the software at any time. The Company does not charge customers an up-front fee for use of the technology. Implementation activities are insignificant and are not subject to a separate fee. In certain cases, the Company charges annual membership fees to customers which are recognized ratably over the one-year membership period. The Company also distributes individual news releases to thousands of distribution points on the Internet, which are then indexed by major search engines and also directly to journalists and other key constituents. Dependent on the nature of the contract with the customer, the Company recognizes revenue on subscription basis over the term of the subscription, or on a per-transaction basis when the press releases are made available to the public. Professional services include broadcast and webcast production. For these services, revenue is recognized when the specific performance is completed and customer acceptance received. Sales and other taxes collected from customers to be remitted to government authorities are excluded from revenues.
Deferred Revenue	Deferred Revenue Deferred revenue consists of payments received from or billings to customers in advance of revenue recognition. Deferred revenue to be recognized in the succeeding twelve-month period is included in current deferred revenue with the remaining amounts included in noncurrent deferred revenue. Invoices issued in advance of the fulfillment of a deliverable or the start of the customers’ subscription term are typically not significant.
Sales Commissions	Sales Commissions Sales commissions relate to the sale of subscription, transaction, and professional services agreements, and are expensed as incurred.
Advertising Costs	Advertising Costs The Company expenses advertising costs as incurred. Advertising costs for the years ended December 31, 2017, 2016 and 2015 were approximately $ 5.9 7.0 8.9
Equity-Based Compensation	Equity-Based Compensation The Company recognizes equity-based
Convertible Preferred Equity Certificates	CPECs were held by Cision Owner and were presented as liabilities in the consolidated balance sheet at December 31, 2016. The CPEC’s were redeemable at any time by the Company and matured 49
Segments	Segments The Company has determined that its Chief Executive Officer is the Chief Operating Decision Maker. The Company’s Chief Executive Officer reviews financial information presented on both a consolidated basis and on a geographic regional basis. Since its inception, the Company has completed several significant acquisitions and has expended significant efforts in integrating these acquisitions into a single commercial software solution, available to all customers in all geographies. As a result of the long-term qualitative and quantitative similar economic characteristics exhibited by the sale of a single product suite in all the Company’s regions, the Company has determined that its operating segments meet the criteria to be aggregated into one reportable segment.
Net Loss per Share	Net Loss per Share Prior to the June 29, 2017 Transactions, net loss per share was calculated using the two-class method. On June 29, 2017, all outstanding classes of equity of Cision were contributed in exchange for 82,075,873 120,512,402
Concentration of Credit Risk	Concentrations of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash and cash equivalents, investments and accounts receivable. The Company generally maintains its cash and cash equivalents with various nationally recognized financial institutions. Customers are granted credit on an unsecured basis. Management monitors the creditworthiness of its customers and believes that it has adequately provided for any exposure to potential credit losses. The Company provides cloud-based software, distribution services and related professional services to various customers across many industries. As of December 31, 2017 and 2016, no individual customer accounted for 10% or more of net accounts receivable. For the years ended December 31, 2017, 2016 and 2015, no individual customer accounted for 10% or more of revenue.
Income Taxes	Income Taxes Income taxes are determined utilizing the asset and liability method whereby deferred tax assets and liabilities are recognized for deductible temporary differences between the respective reported amounts and tax bases of assets and liabilities, as well as for operating loss and tax-credit carryforwards. Net deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized. The Company’s estimates related to liabilities for uncertain tax positions require it to make judgments regarding the sustainability of each uncertain tax position based on its technical merits. If it determines it is more likely than not that a tax position will be sustained based on its technical merits, the Company records the impact of the position in its consolidated financial statements at the largest amount that is greater than fifty percent likely of being realized upon ultimate settlement. The estimates are updated at each reporting date based on the facts, circumstances and information available. The Company is also required to assess at each reporting date whether it is reasonably possible that any significant increases or decreases to its unrecognized tax benefits will occur during the next twelve months. The Company files income tax returns in the U.S. federal jurisdictions and various state and foreign jurisdictions and is subject to U.S. federal, state, and foreign tax examinations for years ranging from 2012 to 2017. On December 22, 2017, the U.S. government enacted comprehensive tax legislation (the “Tax Act”), which contains several key tax provisions that affected the Company including a reduction of the federal corporate income tax rate to 21
