Accounting Policies [Abstract]
Significant Accounting Policies	2. Significant Accounting Policies Basis of Presentation The accompanying consolidated financial statements are presented in conformity with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and the instructions to Form 10-Q. Accordingly, they do not include all the information and footnotes required by GAAP. In the opinion of management, all adjustments (consisting of normal accruals) considered for a fair statement have been included. The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. The condensed consolidated balance sheet as of December 31, 2018 included herein was derived from the audited financial statements as of that date, but does not include all disclosures including notes required by GAAP. Operating results for the six months ended June 30, 2019 are not necessarily indicative of the results that may be expected for the year ending December 31, 2019 or any other period. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K filed with the SEC on March 1, 2019. Certain prior period amounts have been adjusted to conform with the adoption of Accounting Standard Update (“ASU”) 2014-09, Revenue from Contracts with Customers 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 judgements 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. 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. Revenue Recognition The Company accounts for revenue contracts with customers by applying the requirements of Accounting Standards Codification (“ASC”) Topic 606, Revenue from Contracts with Customers (Topic 606) ● Identification of the contract, or contracts with a customer. ● Identification of the performance obligations in the contract. ● Determination of the transaction price. ● Allocation of the transaction price to the performance obligations in the contract. ● Recognition of the revenue when, or as, the Company satisfies a performance obligation. The Company derives its revenue from access to its cloud based technology platform and related media management and analysis services sold on a subscription basis. Revenue is also derived from the distribution of press releases on both a subscription basis and separately from non-subscription arrangements. Dependent on the nature of the distribution contract with the customer, the Company recognizes revenue ratably over the term of the subscription contract, or on a per-transaction basis when the press releases are made available to the public. Subscription services include access to the Company’s software platform and associated hosting services, content and content updates, customer support and media management and analysis services. Subscription services are recognized ratably over the contractual period that the services are delivered, beginning on the date in which such service is made available to the customer. Subscription agreements are typically one year in length and are non-cancelable, though customers have the right to terminate their agreements if the Company materially breaches its obligations under the agreement. Software subscription agreements do not provide customers the right to take possession of the software at any time. The Company does not charge customers an upfront fee for use of the platform and implementation activities are insignificant and not subject to a separate fee. In certain cases, the Company charges annual membership fees which are recognized ratably over the one-year membership period. The Company accounts for a contract when both parties have approved the contract and are committed to perform their respective obligations, each party’s rights can be identified and payment terms can be identified, the contract has commercial substance and it is probable that the Company will collect substantially all of the consideration. Revenue is recognized when, or as, performance obligations are satisfied by transferring control of the promised service to a customer. The transaction price for subscription arrangements and services is generally fixed at contract inception. The Company’s standard payment terms are generally net 30 days. For transaction-based services, which predominantly comprise press release distributions, customers are invoiced in the month the release is made available to the public. In the event that a customer arrangement contains multiple services, the Company determines whether such goods or services are distinct performance obligations that should be accounted for separately in the arrangement. When arrangements contain multiple performance obligations, further evaluation is usually not required given such performance obligations are generally recognized over time using the same measure of progress and thus, are accounted for as a single performance obligation. Otherwise, when allocating the transaction price in the arrangement, the Company uses the estimated standalone selling price of each distinct performance obligation. In order to estimate the standalone selling prices, the Company relies on the price charged for stand-alone sales, expected cost plus margin and adjusted market assessment approaches. Revenue is then recognized over the pattern of performance as each obligation is satisfied as discussed above. As of June 30, 2019, the Company’s remaining performance obligations were $171.8 million, approximately 99.4% of which is expected to be recognized as revenue over the next twelve months and the remainder thereafter. During the six months ended June 30, 2019, the Company recognized $101.3 million in revenue that was recorded as deferred revenue as of December 31, 2018. Recent Accounting Pronouncements New Accounting Pronouncements Adopted We adopted ASU No. 2016-02, Leases (Topic 842) Topic 842 includes multiple changes with one of the most significant impacts being the addition of a right-of-use (“ROU”) asset and a lease liability to the balance sheet for operating leases. A ROU asset represents the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. An additional change under Topic 842 is the lease term evaluation. Under Topic 842, a leasee shall extend the lease term beyond the original contract term if the company is reasonably certain to exercise their renewal option. Upon adoption of the new standard, the Company recognized total ROU assets of approximately $73.2 million, total lease liabilities of approximately $85.3 million, and corresponding adjustments to prepaid expenses of $(0.2) million, deferred rent included in other accrued expenses of $1.8 million, and deferred rent included in other liabilities of $10.5 million on the consolidated balance sheets as of as of January 1, 2019. The standard did not materially impact our consolidated net earnings and had no impact on cash flows. The adoption of the new standard also resulted in significant additional disclosures regarding the Company’s leasing activities, as discussed in Note 5. In February 2018, the FASB issued ASU 2018-02, Income Statement – Reporting Comprehensive Income (Topic 220) Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, which will allow a reclassification from accumulated other comprehensive income to retained earnings for the tax effects resulting from “An Act to Provide for Reconciliation Pursuant to Titles II and V of the Concurrent Resolution on the Budget for Fiscal Year 2018” (the “Act”) that are stranded in accumulated other comprehensive income. This ASU also requires certain disclosures about stranded tax effects; however, it does not change the underlying guidance that requires that the effect of a change in tax laws or rates be included in income from continuing operations. This ASU is effective on January 1, 2019, with early adoption permitted. It must be applied either in the period of adoption or retrospectively to each period in which the effect of the change in the U.S. federal corporate income tax rate in the Act is recognized. The Company adopted ASU 2018-02 during the six months ended June 30, 2019 and it did not have a material impact on the Company’s condensed consolidated financial statements. Recent Accounting Pronouncements Not Yet Effective In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820) In August 2018, the FASB issued ASU 2018-14, Compensation – Retirement Benefits- Defined Benefit Plans – General (Subtopic 715-20) In August 2018, the FASB issued ASU 2018-15, Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40)

Business Combinations and Dispositions	3. Business Combinations and Dispositions Purchase of Prime On January 23, 2018, the Company completed its acquisition of PRIME Research (“Prime”). The purchase price was approximately €75.7 million ($94.1 million) and consisted of approximately €53.1 million ($65.4 million) in cash consideration, the issuance of approximately 1.7 million shares of common stock valued at €16.4 million ($20.1 million), and up to €6.2 million ($8.6 million) of deferred payments due within 18 months. The Company has the discretion to pay up to €2.5 million ($3.1 million) of the deferred payments with common stock. The acquisition of Prime expanded the Company’s comprehensive data-driven offerings that help communications professionals identify influencers, craft meaningful campaigns, and attribute business value to those efforts. At the date of the acquisition, Prime had over 700 employees with offices in Brazil, China, Germany, India, Switzerland, the United Kingdom, and the United States. Total acquisition costs related to the Prime acquisition were $5.4 million of which $2.3 million were incurred during the six months ended June 30, 2018 and the rest were incurred in 2017. Total acquisition costs were included in general and administrative expense in the condensed consolidated statements of operations and comprehensive loss. The acquisition was accounted for under the purchase method of accounting. The operating results are included in the accompanying condensed consolidated financial statements from January 23, 2018. The purchase price has been allocated to the assets acquired and liabilities assumed based on fair values as of the acquisition date. The following table summarizes the allocation of the purchase price by the Company to the fair value of the assets and liabilities of Prime. The identifiable intangible assets include the trade name, customer relationships and purchased technology and are being amortized over three to eleven years on an accelerated basis. The Company completed the purchase price allocation in January 2019. ​ ​ ​ ​ ​ (in thousands) ​ Cash and cash equivalents ​ $ 2,711 Accounts receivable, net ​ 8,186 Prepaid and other assets ​ 1,320 Property, equipment and software, net ​ 1,207 Trade name ​ 1,436 Customer relationships ​ 17,903 Purchased technology ​ 9,881 Goodwill ​ 57,465 Total assets acquired ​ 100,109 Accounts payable, accrued liabilities, and other liabilities ​ (5,627) Deferred revenue ​ (426) Total liabilities assumed ​ (6,053) Net assets acquired ​ $ 94,056 ​ Approximately $39.6 million of goodwill is deductible for tax purposes.

Other 2018 Acquisition During the third quarter of 2018, the Company purchased certain immaterial technology and development assets to expand its products and services offerings, and the results of this acquisition have been included in the consolidated results from the acquisition date. The estimate of fair value for the assets acquired and liabilities assumed was based upon a preliminary calculation and valuation and is subject to change as additional information related to estimates during the measurement period is obtained (up to one year from the acquisition date). The primary areas of those preliminary estimates relate to certain identifiable intangible assets and goodwill. Purchase of Falcon On January 3, 2019, the Company completed its acquisition of Falcon.io (“Falcon”). The purchase price was approximately €103.4 million ($119.0 million) and consisted of approximately €53.6 million ($61.7 million) in cash consideration, the issuance of approximately 5.1 million ordinary shares valued at €49.8 million ($57.3 million), and up to €5.2 million ($6.0 million) of deferred payments due within 12 months in cash of €2.4 million ($2.8 million) and ordinary shares of €2.8 million ($3.2 million). The cash portion of the consideration was funded with a combination of cash on hand and borrowings under the Company’s Revolving Credit Facility. The Company drew approximately $40.0 million under its Revolving Credit Facility in connection with the closing of the Falcon acquisition, all of which was repaid during the six months ended June 30, 2019. The acquisition of Falcon solidifies the Company’s market leadership in driving the future of earned media management, moving beyond the tactical nature of PR point solutions. At the date of the acquisition, Falcon had over 250 employees with offices in Denmark, Germany, Hungary, Australia, Bulgaria, and the United States. Total acquisition costs related to the Falcon acquisition were $2.4 million of which $0.4 million were incurred during the year ended December 31, 2018 and are included in general and administrative expense in the condensed consolidated statements of operations and comprehensive income. The acquisition was accounted for under the purchase method of accounting. The operating results are included in the accompanying condensed consolidated financial statements from January 3, 2019.

Purchase of TrendKite On January 23, 2019, the Company completed its acquisition of TrendKite. The purchase price was approximately $219.0 million and consisted of approximately $94.1 million in cash consideration, the issuance of approximately 10.3 million ordinary shares valued at $124.9 million, and up to $3.2 million of deferred payments due in 12 months in cash of approximately $1.3 million and ordinary shares of approximately $1.9 million.

Leases

Leases [Abstract]
Leases	5. Leases The Company has various non-cancelable operating leases, primarily related to office real estate and datacenters, that expire through 2035 and generally contain renewal options for up to five years. Under ASC 842, the lease term includes options to extend or terminate the lease when the Company is reasonably certain that it will exercise the option. The Company will monitor events or changes in circumstances that impact the timing or amount of future lease payments and will adjust the lease liability and corresponding ROU asset as necessary. For office leases beginning in 2019 and later, the Company accounts for lease components (components of a contract for which the Company economically benefits from their use and is not highly interrelated with other right of use assets underlying the contract such as base rent) separately from the non-lease components (e.g., common-area maintenance costs). For datacenter leases beginning in 2019 and later, the Company elected the practical expedient to combine its lease and non-lease components that meet the defined criteria and will account for the lease component under Topic 842. The Company has no significant financing leases. Lastly, the Company has not entered into any future office space leases that will create significant rights and obligations for the Company. At inception of a contract, the Company determines if the contract contains a lease based on requirements of ASC 842. If a lease with a term greater than 1 year is identified, the Company will add a ROU asset and lease liability to the balance sheet. The Company has elected the practical expedient and expenses all leases with a contract term of 1 year or less. The Company recognizes a lease liability based on the net present value of total lease payments which utilizes an implicit discount rate based on the Company’s collateralized borrowing rate placed on a yield curve. The incremental borrowing rate for a lease is the rate of interest the Company would have to pay on a collateralized basis to borrow an amount equal to the lease payments under similar terms. To derive the ROU asset, the Company makes required adjustments, such as indirect costs and prepaid or deferred balances, to the lease liability. We recognize operating lease expense on a straight-line basis over the term of the lease within operating expenses and cost of revenue. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three months ended ​ Six months ended Lease Cost (in thousands) June 30, 2019 June 30, 2019 Operating lease cost $ 3,791 $ 9,557 Short-term lease cost ​ ​ 1,053 ​ ​ 1,665 Variable lease cost ​ ​ 3,011 ​ ​ 4,127 Sublease income ​ ​ (255) ​ ​ (436) Total lease cost $ 7,600 $ 14,913 ​ ​ ​ ​ ​ ​ ​ ​ Operating leases (thousands) Classification June 30, 2019 ​ ​ ​ ​ ​ ​ Operating right-of-use assets Operating right-of-use assets $ 61,841 ​ ​ ​ ​ ​ ​ ​ ​ Operating lease liabilities (current) Operating lease liabilities (current) ​ ​ 14,214 ​ Operating lease liabilities (net of current portion) Operating lease liabilities (net of current portion) ​ ​ 62,972 ​ Total operating lease liabilities ​ ​ $ 77,186 ​ ​ ​ ​ ​ ​ ​ ​ Weighted average remaining lease term ​ ​ ​ ​ 6.9 years ​ Weighted average discount rate ​ ​ ​ ​ 5.2 % ​ The following is a schedule, by years, of maturities of lease liabilities as of June 30, 2019 (in thousands): ​ ​ ​ ​ ​ Remainder of 2019 $ 9,214 2020 ​ ​ 17,206 2021 ​ ​ 14,572 2022 ​ ​ 12,579 2023 ​ ​ 8,529 Thereafter ​ ​ 32,834 Total lease payments ​ ​ 94,934 Less: imputed interest ​ ​ (17,748) Present value of lease liabilities $ 77,186 ​ As previously disclosed in our 2018 Form 10-K and under the previous lease accounting standard, future minimum lease payments under non-cancelable operating leases as of December 31, 2018 were as follows (in thousands): ​ ​ ​ ​ 2019 $ 16,288 2020 ​ ​ 15,682 2021 ​ ​ 13,416 2022 ​ ​ 12,494 2023 ​ ​ 8,806 Thereafter ​ ​ 27,773 Total future minimum payments $ 94,459 ​ ​ ​ ​ ​ ​ ​ Six months ended ​ June 30, 2019 Cash paid for amounts included in the measurement of lease liabilities ​ ​ ​ Operating cash flows from operating leases $ 9,019 ROU assets obtained in exchange for new operating lease liabilities ​ ​ ​ Operating leases $ (5,719) ​

The 2017 First Lien Credit Facility provided for a tranche of refinancing term loans which refinanced the term loans under the 2016 First Lien Credit Facility in full and provided for additional term loans of $131.2 million. Upon effectiveness of the 2017 First Lien Credit Facility, the 2017 First Lien Credit Facility consists of: (i) a revolving credit facility, which permits borrowings and letters of credit of up to $75.0 million (the “2017 Revolving Credit Facility”), of which up to $25.0 million may be used or issued as standby and trade letters of credit; (ii) a $960.0 million Dollar-denominated term credit facility (the “2017 First Lien Dollar Term Credit Facility”); and (iii) a €250.0 million Euro-denominated term credit facility (the “2017 First Lien Euro Term Credit Facility”) and, together with the 2017 First Lien Dollar Term Credit Facility, the “2017 First Lien Term Credit Facility” and collectively with the 2017 Revolving Credit Facility, the “2017 First Lien Credit Facility”). The Company used the proceeds from the 2017 First Lien Term Credit Facility to repay all amounts then outstanding under the 2016 First Lien Credit Facility, all amounts outstanding under the 2016 Second Lien Credit Facility, pay all related fees and expenses, and retained remaining cash for general corporate purposes. The Company terminated the 2016 Second Lien Credit Facility in connection with establishing the 2017 First Lien Credit Facility. On December 14, 2017, the Company amended the 2017 First Lien Credit Facility to borrow an additional $75.0 million of 2017 First Lien Dollar Term Credit Facility. The Company used the money for its acquisition of Prime Research Group. On February 8, 2018, the Company completed its debt repricing transaction on its 2017 First Lien Credit Facility. The margins on the term loans under the 2017 First Lien Credit Facility were lowered for the alternate base rate, LIBOR rate and EURIBOR rate by 1.00%, 1.00% and 0.75%, respectively. The 2017 Revolver Credit Facility margins were lowered for the alternate base rate, LIBOR rate and EURIBOR rate by 0.75%, 0.75% and 0.50%, respectively. The Company incurred approximately $2.0 million in financing costs in connection with the February 2018 repricing of the 2017 First Lien Credit Facility of which $0.1 million are being amortized using the effective interest method. As a result of this transaction, the Company recorded a loss on extinguishment of $2.4 million. On October 22, 2018, the Company completed another debt repricing transaction on its 2017 First Lien Credit Facility. The margins for the term loans under the Company’s 2017 First Lien Credit Facility were lowered for the alternate base rate, LIBOR rate and EURIBOR rate each by 0.50%. The 2017 Revolving Credit Facility margins were lowered for the alternate base rate, LIBOR rate, and EURIBOR rate each by 0.50%. The Company incurred approximately $2.3 million in financing costs in connection with the October 2018 repricing of the 2017 First Lien Credit Facility, of which $0.3 million are being amortized using the effective interest method. As a result of this transaction, the Company recorded a loss on extinguishment of $7.0 million. On December 28, 2018, the Company entered into an Incremental Facility Amendment to increase the revolving credit facility by $25.0 million from $75.0 million to $100.0 million. The Company drew approximately $40.0 million of dollar borrowings under its Revolving Credit Facility in connection with the closing of the Falcon acquisition, all of which was repaid during the three months ended March 31, 2019. On January 11, 2019, the Company amended the 2017 First Lien Facility to borrow an additional $75.0 million of the 2017 First Lien Dollar Term Credit Facility. The Company used the money for its acquisition of TrendKite. As a result of this transaction, the Company recorded a loss on extinguishment of $0.4 million. The obligations under the 2017 First Lien Credit Facility are collateralized by substantially all of the assets of Cision’s subsidiary, Canyon Companies S.à.r.l. and each of its subsidiaries organized in the United States (or any state thereof), the United Kingdom, the Netherlands, Luxembourg, and Ireland, subject to certain exceptions. Interest is charged on U.S. dollar borrowings under the 2017 First Lien Credit Facility, at the Company’s option, at a rate based on (1) the adjusted LIBOR (a rate equal to the London interbank offered rate adjusted for statutory reserves) or (2) the alternate base rate (a rate that is highest of the (i) Deutsche Bank AG, New York Branch’s prime lending rate, (ii) the overnight federal funds rate plus 50 basis points or (iii) the one-month adjusted LIBOR plus 1%), in each case, plus an applicable margin. The margin applicable to loans under the 2017 First Lien Dollar Term Credit Facility bearing interest at the alternate base rate is 3.25%; the margin applicable to loans under the 2017 First Lien Dollar Term Credit Facility bearing interest at the adjusted LIBOR is 4.25%, provided that each such rate is reduced by 25 basis points if the first lien net leverage ratio of Canyon Companies S.à.r.l. and its restricted subsidiaries under the 2017 First Lien Credit Facility is less than or equal to 4.00:1.00 at the end of the most recent fiscal quarter. Interest is charged on Euro borrowings under the 2017 First Lien Credit Facility at a rate based on the adjusted EURIBOR (a rate equal to the Euro interbank offered rate adjusted for statutory reserves), plus an applicable margin. The margin applicable to loans under the 2017 First Lien Euro Term Credit Facility bearing interest at the adjusted LIBOR is 4.25%, provided that each such rate is reduced by 25 basis points if the first lien net leverage ratio of Canyon Companies S.à.r.l. and its restricted subsidiaries under the 2017 First Lien Credit Facility is less than or equal to 4.00:1.00 at the end of the most recent fiscal quarter. As of June 30, 2019, the applicable interest rate under the 2017 First Lien Dollar Term Credit Facility and the 2017 First Lien Euro Term Credit Facility was 5.08% and 3.00%, respectively. The margin applicable to loans under the 2017 Revolving Credit Facility bearing interest at the alternate base rate, the adjusted LIBOR, and the adjusted Euro interbank offered rate bear interest at rates of 3.00%, 4.00%, and 4.00% respectively; provided that each such rate is reduced by 25 basis points if the first lien net leverage ratio of Canyon Companies S.à.r.l. and its restricted subsidiaries under the 2017 First Lien Credit Facility is less than or equal to 4.00:1.00 at the end of the most recent fiscal quarter. The maturity dates of the 2017 Revolving Credit Facility and the 2017 First Lien Term Credit Facility are June 16, 2022 and June 16, 2023, respectively. As of June 30, 2019, the Company had no outstanding borrowings and $2.0 million of outstanding letters of credit under the 2017 Revolving Credit Facility and $1,321.2 million outstanding under the 2017 First Lien Credit Facility. The Company began to make quarterly principal payments starting December 31, 2017 under each of the 2017 First Lien Dollar Term Credit Facility of $2.8 million and the 2017 First Lien Euro Term Credit Facility of €0.6 million (which amount may be reduced by the application of voluntary and mandatory prepayments pursuant to the terms of the 2017 First Lien Credit Facility), with the remaining balance due June 16, 2023. The Company may also be required to make certain mandatory prepayments of the 2017 First Lien Credit Facility out of excess cash flow and upon the receipt of proceeds of asset sales and certain insurance proceeds (in each case, subject to certain minimum dollar thresholds and rights to reinvest the proceeds as set forth in the 2017 First Lien Credit Facility). The 2017 First Lien Credit Facility includes a total net leverage financial maintenance covenant. Such covenant requires that, as of the last day of each fiscal quarter, the total net leverage ratio of Canyon Companies S.à.r.l. and its restricted subsidiaries under the 2017 First Lien Credit Facility cannot exceed the applicable ratio set forth in the 2017 First Lien Credit Facility for such quarter (subject to certain rights to cure any failure to meet such ratio as set forth in the 2017 First Lien Credit Facility). The 2017 First Lien Credit Facility is also subject to certain customary affirmative covenants and negative covenants. Under the 2017 First Lien Credit Facility, the Company’s subsidiaries have restrictions on making cash dividends, subject to certain exceptions, including that the subsidiaries are permitted to declare and pay cash dividends: (a) in any amount, so long as the total net leverage ratio under the 2017 First Lien Credit Facility would not exceed 3.75 to 1.00 after making such payment; (b) in an amount per annum not greater than 6.0% of (i) the market capitalization of the Company’s common stock (based on the average closing price of its shares during the 30 trading days preceding the declaration of such payment) plus (ii) the $305.2 million in proceeds we received in the business combination with Capitol; (c) in an amount that does not exceed the sum of (i) $20.0 million, plus (ii) 50% of consolidated net income of the Company’s subsidiaries from January 1, 2016 to the end of the most recent quarter plus (iii) certain other amounts set forth in the definition of “Available Amount” in the Company’s 2017 First Lien Credit Facility (provided that it may only include the amounts of consolidated net income described in clause (ii) if the Company’s total net leverage ratio would not exceed 5.00 to 1.00 after making such payment); and (d) in an amount that does not exceed the total net proceeds we receive from any public or private offerings of its common stock or similar equity interests. As of June 30, 2019, the Company was in compliance with these covenants. The 2017 First Lien Credit Facility provides that an event of default will occur upon specified change of control events. “Change in Control” is defined to include, among other things, the failure by Cision Owner, its affiliates and certain other “Permitted Holders” to beneficially own, directly or indirectly through one or more holding company parents of Cision, a majority of the voting equity of the borrower thereunder. The fair value of the Company’s First Lien Credit Facility at June 30, 2019 and December 31, 2018 was $1,311.3 million and $1,210.5 million, respectively.

Common Stock The Company is authorized to issue 480,000,000 shares of common stock with a par value of $0.0001 per share. Equity-based compensation is classified in the condensed consolidated statements of operations and comprehensive loss in a manner consistent with the statements of operations’ classification of an employee’s salary and benefits as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three months ended June 30, Six months ended June 30, (in thousands) 2019 2018 2019 2018 Cost of revenue ​ $ 115 ​ $ 89 ​ $ 217 ​ $ 225 Selling and marketing ​ 347 ​ 136 ​ 627 ​ 224 Research and development ​ 269 ​ 110 ​ 523 ​ 233 General and administrative ​ 1,831 ​ 533 ​ 3,276 ​ 1,527 Total equity-based compensation expense ​ $ 2,562 ​ $ 868 ​ $ 4,643 ​ $ 2,209 ​ The 2017 Omnibus Incentive Plan In June 2017, the Company adopted the 2017 Omnibus Incentive Plan (the “2017 Plan”). The 2017 Plan provides for grants of stock options, stock appreciation rights, restricted stock, other stock-based awards and other cash-based awards. Directors, officers and other employees of the Company and its subsidiaries, as well as others performing consulting or advisory services for the Company, are eligible for grants under the 2017 Plan. The 2017 Plan reserved up to 6,100,000 shares of common stock of the Company for issuance in accordance with the plan’s terms, subject to certain adjustments. The purpose of the plan is to provide the Company’s officers, directors, employees and consultants who, by their position, ability and diligence are able to make important contributions to the Company’s growth and profitability, with an incentive to assist the Company in achieving its long-term corporate objectives, to attract and retain executive officers and other employees of outstanding competence and to provide such persons with an opportunity to acquire an equity interest in the Company. Stock options are granted with an exercise price equal to the market value of the Company’s common stock at the grant date and generally vest over four years based upon continuous service and expire ten years from the grant date. Restricted stock units are granted with an exercise price equal to the market value of the Company’s common stock at the time of grant. Conditions of the performance-based restricted stock units are based on achievement of pre-established performance goals and objectives within the next year and vest over four years based on continuing employment. Conditions of the performance-based stock options are also based on achievement of pre-established performance goals and objectives within the next year, vest over four years based on continuing employment, and have an expiration of ten years. The Company estimated the fair value of employee stock options using the Black-Scholes option pricing model. The fair values of stock options granted under the 2017 Plan were estimated using the following assumptions: ​ ​ ​ ​ ​ ​ Six months ended June 30, 2019 ​ Stock price volatility 42.0 % Expected term (years) 6.3 ​ Risk-free interest rate 2.5 % Dividend yield — % ​ A summary of employee stock option activity for the six months ended June 30, 2019 under the Company’s 2017 Plan is presented below: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Weighted- Weighted- ​ ​ ​ ​ ​ ​ Average ​ Average ​ Aggregate ​ ​ ​ ​ Exercise ​ Contractual ​ Intrinsic ​ ​ Number of ​ Price per ​ Term ​ Value ​ ​ Options ​ Share ​ (Years) ​ (thousands) Options outstanding as of December 31, 2018 2,112,500 ​ $ 14.43 9.3 ​ ​ — Granted 1,070,000 ​ 12.32 — ​ Exercised (43,125) ​ 12.78 — ​ Forfeited (834,250) ​ 13.93 — ​ Options outstanding as of June 30, 2019 2,305,125 ​ $ 13.66 9.2 ​ $ — Options vested as of June 30, 2019 119,000 ​ $ 12.59 8.3 ​ $ — ​ The aggregate intrinsic value is calculated as the difference between the exercise price of the underlying stock option awards and the quoted closing price of the Company’s common stock as of June 30, 2019.

Employee Stock Purchase Plan As of December 17, 2018, the Company commenced an Employee Stock Purchase Plan (“ESPP”) to allow eligible employees to have up to 10 percent of their annualized base salary withheld and used to purchase common stock, subject to a maximum of $5,000 worth of stock purchased in a calendar year. The price per share of the stock sold to Participants hereunder shall be the product of ninety percent (90%) multiplied by the lower of: (i) the Fair Market Value of such share on the Entry Date of the Option Period in which the Employee elects to become a participant; and (ii) the Fair Market Value of such share on the Exercise Date with respect to such Option Period: provided, however

Earnings Per Share [Abstract]
Net Income (Loss) Per share	8. Net Income (Loss) Per share Basic net income (loss) per share is computed by dividing net loss by the weighted-average number of shares of common stock outstanding during the period. For the three and six months ended June 30, 2019, the Company has excluded 2,000,000 earn out shares as the effect would be anti-dilutive. During the three months ended June 30, 2018, all warrants were converted to 6,342,989 common shares. For the three and six months ended June 30, 2018, the Company has excluded the potential effect of the warrants prior to their conversion, additional earn out shares, and the dilutive effect of stock options and restricted stock awards, as described in Note 7, in the calculation of diluted loss per share, as the effect would be anti-dilutive due to losses incurred. As a result, diluted income (loss) per common share is the same as basic income (loss) per common share for all periods presented below. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three months ended June 30, ​ Six months ended June 30, (in thousands, except share and per share data) 2019 2018 2019 2018 Numerator: ​ ​ ​ ​ Net income (loss) ​ $ (7,758) ​ $ (6,583) ​ $ 3,876 ​ $ (7,025) Denominator: ​ ​ ​ ​ Weighted-average shares outstanding ​ ​ 148,070,969 ​ ​ 127,392,151 ​ ​ 146,749,612 ​ ​ 125,678,727 Effect of dilutive common stock equivalents ​ ​ — ​ ​ — ​ ​ 83,923 ​ ​ — Weighted-average shares outstanding ​ ​ 148,070,969 ​ ​ 127,392,151 ​ ​ 146,833,535 ​ ​ 125,678,727 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Net income (loss) per share - basic ​ $ (0.05) ​ $ (0.05) ​ $ 0.03 ​ $ (0.06) Net income (loss) per share- diluted ​ $ (0.05) ​ $ (0.05) ​ $ 0.03 ​ $ (0.06) ​

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	9. Income Taxes The provision for income taxes is based on the current estimate of the annual effective tax rate adjusted to reflect the tax impact of items discrete to the fiscal period. The annual effective tax rate calculation excludes subsidiaries with pre-tax losses for which no tax benefit can be recognized. The Company estimates its annual effective tax rate to be approximately 51.4% in 2019. The provision for income taxes results in an effective tax rate of 69.7% for the six months ended June 30, 2019. The difference between the annual effective tax rate and the effective tax rate in the quarter is due to subsidiaries with pre-tax losses for which no tax benefit can be recognized and subsidiaries with pre-tax losses in jurisdictions with a zero percent tax rate that have been removed from pre-tax book income before the annual effective tax rate is applied. The amount of pre-tax book loss removed is approximately $10.7 million. The difference also includes the impact of a $3.2 million benefit primarily related to a change to the valuation allowance that is discrete to the fiscal period. This rate includes the impact of United States and Foreign permanent differences and a decrease in the valuation allowance for certain disallowed interest in the United States. The United States permanent differences are primarily related to the gain on the sale of the iContact assets related to Goodwill, nondeductible transaction costs, nondeductible public company costs, nondeductible equity compensation and income from Canadian subsidiaries that is taxable in the United States as a result of the Tax Cuts and Jobs Act of 2017 (the “Tax Act”). The Foreign permanent differences are primarily related to nondeductible interest expense in the United Kingdom. The decrease in the valuation allowance in the U.S. is related to tax deferred interest expense. The provision for income tax for the six months ended June 30, 2018 was $6.9 million. The provision for income tax for the six months ended June 30, 2018 was primarily driven by using the annual effective tax rate methodology and removing $6.7 million of pre-tax losses for which no tax benefit can be recognized before the annual effective tax rate is applied. It is also impacted by non-deductible permanent differences and the increase in the valuation allowance for disallowed interest in the United States. 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 condensed 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. As of June 30, 2019, the Company believes the reasonably possible total amount of unrecognized tax benefits that could increase or decrease in the next twelve months as a result of various statute expirations, audit closures, and/or tax settlements would not be material to its condensed consolidated financial statements.

Accounting Policies [Abstract]
Basis of Presentation and Earnings per Share	Basis of Presentation The accompanying consolidated financial statements are presented in conformity with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and the instructions to Form 10-Q. Accordingly, they do not include all the information and footnotes required by GAAP. In the opinion of management, all adjustments (consisting of normal accruals) considered for a fair statement have been included. The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. The condensed consolidated balance sheet as of December 31, 2018 included herein was derived from the audited financial statements as of that date, but does not include all disclosures including notes required by GAAP. Operating results for the six months ended June 30, 2019 are not necessarily indicative of the results that may be expected for the year ending December 31, 2019 or any other period. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K filed with the SEC on March 1, 2019. Certain prior period amounts have been adjusted to conform with the adoption of Accounting Standard Update (“ASU”) 2014-09, Revenue from Contracts with Customers
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 judgements 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.
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.
Revenue Recognition	Revenue Recognition The Company accounts for revenue contracts with customers by applying the requirements of Accounting Standards Codification (“ASC”) Topic 606, Revenue from Contracts with Customers (Topic 606) ● Identification of the contract, or contracts with a customer. ● Identification of the performance obligations in the contract. ● Determination of the transaction price. ● Allocation of the transaction price to the performance obligations in the contract. ● Recognition of the revenue when, or as, the Company satisfies a performance obligation. The Company derives its revenue from access to its cloud based technology platform and related media management and analysis services sold on a subscription basis. Revenue is also derived from the distribution of press releases on both a subscription basis and separately from non-subscription arrangements. Dependent on the nature of the distribution contract with the customer, the Company recognizes revenue ratably over the term of the subscription contract, or on a per-transaction basis when the press releases are made available to the public. Subscription services include access to the Company’s software platform and associated hosting services, content and content updates, customer support and media management and analysis services. Subscription services are recognized ratably over the contractual period that the services are delivered, beginning on the date in which such service is made available to the customer. Subscription agreements are typically one year in length and are non-cancelable, though customers have the right to terminate their agreements if the Company materially breaches its obligations under the agreement. Software subscription agreements do not provide customers the right to take possession of the software at any time. The Company does not charge customers an upfront fee for use of the platform and implementation activities are insignificant and not subject to a separate fee. In certain cases, the Company charges annual membership fees which are recognized ratably over the one-year membership period. The Company accounts for a contract when both parties have approved the contract and are committed to perform their respective obligations, each party’s rights can be identified and payment terms can be identified, the contract has commercial substance and it is probable that the Company will collect substantially all of the consideration. Revenue is recognized when, or as, performance obligations are satisfied by transferring control of the promised service to a customer. The transaction price for subscription arrangements and services is generally fixed at contract inception. The Company’s standard payment terms are generally net 30 days. For transaction-based services, which predominantly comprise press release distributions, customers are invoiced in the month the release is made available to the public. In the event that a customer arrangement contains multiple services, the Company determines whether such goods or services are distinct performance obligations that should be accounted for separately in the arrangement. When arrangements contain multiple performance obligations, further evaluation is usually not required given such performance obligations are generally recognized over time using the same measure of progress and thus, are accounted for as a single performance obligation. Otherwise, when allocating the transaction price in the arrangement, the Company uses the estimated standalone selling price of each distinct performance obligation. In order to estimate the standalone selling prices, the Company relies on the price charged for stand-alone sales, expected cost plus margin and adjusted market assessment approaches. Revenue is then recognized over the pattern of performance as each obligation is satisfied as discussed above. As of June 30, 2019, the Company’s remaining performance obligations were $171.8 million, approximately 99.4% of which is expected to be recognized as revenue over the next twelve months and the remainder thereafter. During the six months ended June 30, 2019, the Company recognized $101.3 million in revenue that was recorded as deferred revenue as of December 31, 2018.
Recent Accounting Pronouncements	Recent Accounting Pronouncements New Accounting Pronouncements Adopted We adopted ASU No. 2016-02, Leases (Topic 842) Topic 842 includes multiple changes with one of the most significant impacts being the addition of a right-of-use (“ROU”) asset and a lease liability to the balance sheet for operating leases. A ROU asset represents the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. An additional change under Topic 842 is the lease term evaluation. Under Topic 842, a leasee shall extend the lease term beyond the original contract term if the company is reasonably certain to exercise their renewal option. Upon adoption of the new standard, the Company recognized total ROU assets of approximately $73.2 million, total lease liabilities of approximately $85.3 million, and corresponding adjustments to prepaid expenses of $(0.2) million, deferred rent included in other accrued expenses of $1.8 million, and deferred rent included in other liabilities of $10.5 million on the consolidated balance sheets as of as of January 1, 2019. The standard did not materially impact our consolidated net earnings and had no impact on cash flows. The adoption of the new standard also resulted in significant additional disclosures regarding the Company’s leasing activities, as discussed in Note 5. In February 2018, the FASB issued ASU 2018-02, Income Statement – Reporting Comprehensive Income (Topic 220) Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, which will allow a reclassification from accumulated other comprehensive income to retained earnings for the tax effects resulting from “An Act to Provide for Reconciliation Pursuant to Titles II and V of the Concurrent Resolution on the Budget for Fiscal Year 2018” (the “Act”) that are stranded in accumulated other comprehensive income. This ASU also requires certain disclosures about stranded tax effects; however, it does not change the underlying guidance that requires that the effect of a change in tax laws or rates be included in income from continuing operations. This ASU is effective on January 1, 2019, with early adoption permitted. It must be applied either in the period of adoption or retrospectively to each period in which the effect of the change in the U.S. federal corporate income tax rate in the Act is recognized. The Company adopted ASU 2018-02 during the six months ended June 30, 2019 and it did not have a material impact on the Company’s condensed consolidated financial statements. Recent Accounting Pronouncements Not Yet Effective In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820) In August 2018, the FASB issued ASU 2018-14, Compensation – Retirement Benefits- Defined Benefit Plans – General (Subtopic 715-20) In August 2018, the FASB issued ASU 2018-15, Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40)
