Summary of Significant Accounti

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation The unaudited condensed consolidated financial statements included herein have been prepared by Criteo S.A. pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC"). Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP") have been condensed or omitted pursuant to such rules and regulations. However, the Company believes that the disclosures are adequate to make the information presented not misleading. These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto included in the Company's Annual Report filed on Form 10-K for the year ended December 31, 2015 , filed with the SEC on February 29, 2016. The unaudited condensed consolidated financial statements included herein reflect all adjustments (consisting of normal, recurring adjustments) which are, in the opinion of management, necessary to state fairly the results for the interim periods presented. The results of operations for the interim periods presented are not necessarily indicative of the operating results to be expected for any subsequent interim period or for the fiscal year. Conformity with U.S. GAAP requires the use of estimates and judgments that affect the reported amounts of assets, liabilities, revenue and expenses in the condensed consolidated financial statements and accompanying notes. We base our estimates and judgments on historical information and on various other assumptions that we believe are reasonable under the circumstances. Our actual results may differ from these estimates. U.S. GAAP requires us to make estimates and judgments in several areas, including, but not limited to: (1) the recognition of revenue; (2) the evaluation of our trade receivables and the recognition of a valuation allowance; (3) the recognition and measurement of goodwill and intangible assets and particularly costs capitalized in relation to our customized internal-use software; (4) the measurement of share-based compensation and (5) the tax provision determination and particularly the estimate of our annual effective tax rate. There have been no changes to our significant accounting policies described in our Annual Report on Form 10-K for the fiscal year ended December 31, 2015 that have had a material impact on our unaudited condensed consolidated financial statements and related notes. Recently Issued Accounting Standards In September 2015, the FASB issued ASU 2015-16 , Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments . ASU 2015-16 requires an acquirer to recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined, including the cumulative effect of the change in provisional amount, as if the accounting had been completed at the acquisition date. The Company does not expect the provision of ASU 2015-16 to have a material impact on its consolidated financial statements. This update will be effective for fiscal years beginning after December 15, 2016, and interim periods within fiscal years beginning after December 15, 2017. Early adoption is permitted for financial statements that have not yet been made available for issuance. In January 2016, the FASB issued ASU 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities . ASU 2016-01 requires that all financial assets and liabilities not accounted for under the equity method be measured at fair value, with the changes in fair value recognized in net income. The amendments in this update also require an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments. In addition, the amendments in this update supersede the requirement to disclose the methods and significant assumptions used in calculating the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet for public business entities. The Company can early adopt the provision requiring it to recognize in other comprehensive income the fair value change from instrument-specific credit risk measured using the fair value option for financial instruments. Except for this early application guidance, early adoption is not permitted. The Company is still evaluating the effects that the provision of ASU 2016-01 will have on its consolidated financial statements. This update will be effective for fiscal years beginning after December 15, 2018, and interim periods within fiscal years beginning after December 15, 2019. Early adoption as of fiscal years beginning after December 15, 2017, including interim periods within those fiscal year, is permitted. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) . ASU 2016-02 requires an entity to recognize a right-of-use asset and lease liability for all leases with terms of more than 12 months. Recognition, measurement and presentation of expenses will depend on classification as a finance or operating lease. The amendments also require certain quantitative and qualitative disclosures about leasing arrangements. Early adoption is permitted. The updated guidance requires a modified retrospective adoption. The Company is still evaluating the effects that the provision of ASU 2016-02 will have on its consolidated financial statements. This update will be effective for fiscal years beginning after December 15, 2019, and interim periods within fiscal years beginning after December 15, 2020. Early application is permitted. In March 2016, the FASB issued ASU 2016-08, Principal Versus Agent Considerations (Reporting Revenue Gross Versus Net) . ASU 2016-08 amends the principal-versus-agent implementation guidance and illustrations in the FASB's new revenue standard Revenue from Contracts with Customers (ASC Topic 606) . The Company is currently evaluating the impact of ASU 2016-08 on its consolidated financial statements. This update will be effective for fiscal years beginning after December 15, 2018, and interim periods within annual reporting periods beginning after December 15, 2019. Earlier application is permitted only as of fiscal years beginning after December 15, 2016, including interim periods within that fiscal year, or fiscal years beginning after December 15, 2016, and interim periods within fiscal years beginning one year after the fiscal year in which an entity first applies the guidance in Update 2014-09. In March 2016 the FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting . ASU 2016-09 was issued as part of FASB’s initiative to reduce complexity in accounting standards. The areas for simplification in this update involve several aspects of the accounting for employee share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. This update will be effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods. Early adoption is permitted in any interim or annual period. In April 2016 the FASB issued ASU 2016-10, Identifying Performance Obligations and Licensing . ASU 2016-10 clarifies guidance related to identifying performance obligations and licensing implementation guidance contained in the new revenue standard Revenue from Contracts with Customers (ASC Topic 606) . The Company is currently evaluating the impact of ASU 2016-10 on its consolidated financial statements. The effective date of ASU 2016-10 is the same as for requirements of ASC Topic 606. In May 2016 the FASB issued ASU 2016-11, Rescission of SEC Guidance Because of Accounting Standards Updates 2015-09 and 2014-06 Pursuant to Staff Announcements at the March 3, 2016 EITF Meeting (SEC Update). ASU 2016-11 rescinds certain SEC Staff Guidance relating to ASC topics 605 (Revenue Recognition), 932 (Extractive Activities - Oil and Gas), and 815 (Derivatives and Hedging). The ASU became effective immediately. The Company has evaluated the rescinded SEC Staff Guidance and determined it does not have an impact on the consolidated financial statements. In May 2016 the FASB issued ASU 2016-12, Narrow Scope Improvements and Practical Expedients. ASU 2016 - 12 amends narrow aspects of the new revenue standard Revenue from Contracts with Customers (ASC Topic 606) including guidance on assessing collectability, presentation of sales taxes, noncash consideration, and completed contracts and contract modifications at transition. The Company is currently evaluating the impact of ASU 2016-12 on its consolidated financial statements. The effective date of ASU 2016-12 is the same as for requirements of ASC Topic 606. In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326) Measurement of Credit Losses on Financial Statements . ASU 2016-13 amends the guidance on the impairment of financial instruments. Under the new guidance, an entity recognizes as an allowance its estimate of expected credit losses rather than incurred credit losses. In addition, this amendment broadens the information an entity must consider in developing its expected credit loss estimate including the use of forecasts in order to ensure more timely information is used to develop the estimate. The Company is currently evaluating the impact of ASU 2016-13 on its consolidated financial statements. This update will be effective for fiscal years beginning after December 15, 2020, including interim periods within that fiscal year. In August 2016, the FASB issued ASU 2016-14, Not-for-Profit Entities (Topic 958) Presentation of Financial Statements of Not-for-Profit Entities. As this ASU relates to not-for-profit entities only, it is not applicable to Criteo and it does not have an impact on the consolidated financial statements. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230) Classification of Certain Cash Receipts and Cash Payments. ASU 2016-15 amends current U.S. GAAP by adding specific guidance on eight cash flows issues in order to eliminate the current diversity in reporting practices. The eight issues addressed include debt prepayment or debt extinguishment costs, settlement of zero-coupon debt instruments or other debt instruments with coupon interest rates that are insignificant in relation to the effective interest rate of the borrowing, contingent consideration payments made after a business combination, proceeds from the settlement of insurance claims, proceeds from the settlement of corporate owned life insurance policies, distributions received from equity method investees, beneficial interests in securitization transactions and separately identifiable cash flows and application of the predominance principle. The Company is currently evaluating the impact of ASU 2016-15 on its consolidated financial statements. This update will be effective for fiscal years beginning after December 15, 2018, and interim periods beginning after December 15, 2019. Early adoption is permitted in any interim or annual period.

Intangible assets and Goodwill	Intangible assets and Goodwill Intangible assets The main changes in intangible assets since December 31, 2015 relate to additions to technology and customer relationships regarding Monsieur Drive, which were identified as intangible assets further to the preliminary purchase price allocation (Note 2). In addition, no triggering events have occurred which would indicate impairment in the balance of either intangible assets or goodwill. The estimated amortization expense related to intangible assets for the next five years and thereafter is as follows: Software Technology and customer relationships Total Remainder of 2016 $ (1,151 ) $ (1,035 ) $ (2,186 ) 2017 (4,212 ) (3,053 ) (7,265 ) 2018 (3,602 ) (2,483 ) (6,085 ) 2019 (1,952 ) (505 ) (2,457 ) 2020 (591 ) — (591 ) Thereafter (11 ) — (11 ) Total $ (11,519 ) $ (7,076 ) $ (18,595 ) Goodwill On May 31, 2016, we acquired all of the outstanding shares of Monsieur Drive. The total consideration paid was $5.1 million ( €4.6 million ) for the acquisition of the shares, financed by the available cash resources at the acquisition date. This business combination has been accounted for under the acquisition method in accordance with ASC 805 – Business Combinations . A preliminary valuation of the fair value of Monsieur Drive's assets acquired, liabilities assumed and the related allocation of purchase price has been performed as of September 30, 2016, resulting in the identification of a technology asset of $1.4 million ( €1.3 million ) and related deferred tax liability of $0.2 million ( €0.2 million ). Residual goodwill has been valued at $3.9 million ( €3.5 million ). Once this valuation analysis is finalized, the estimate of the fair value of the assets acquired and liabilities assumed may be adjusted. In addition, acquisition costs amounting to $0.2 million ( €0.2 million ) were fully expensed as incurred.

To calculate our estimated AETR, we estimate our income before taxes and the related tax expense or benefit for the full fiscal year (total of expected current and deferred tax provisions), excluding the effect of significant unusual or infrequently occurring items or comprehensive income items not recognized in the statement of income. Each quarter, we update our estimate of the annual effective tax rate, and if our estimated annual tax rate changes, we make a cumulative adjustment in that quarter. Our quarterly tax provision, and our quarterly estimate of our annual effective tax rate, are subject to significant volatility due to several factors including our ability to accurately predict our income (loss) before provision for income taxes in multiple jurisdictions and the changes in foreign exchange rates. Our effective tax rate in the future will depend on the portion of our profits earned within and outside of France. Current tax assets and liabilities The total amount of current tax assets consists mainly of prepayments of income taxes by Criteo do Brasil LTDA and withholding taxes deductible from future income taxes of Criteo Corp. The current tax liabilities refers mainly to the net corporate tax payables of Criteo S.A., Criteo Srl, and Criteo KK.

There were no other potentially dilutive instruments outstanding as of September 30, 2015 and 2016 . Consequently all potential dilutive effects from shares are considered. For each period presented, a contract to issue a certain number of shares (i.e. share option, non-employee warrant ("BSA"), restricted share unit ("RSU") or non-employee warrant ("BSPCE") is assessed as potentially dilutive if it is “in the money” (i.e., the exercise or settlement price is lower than the average market price).

Subsequent Events	Subsequent Events On October 3, 2016, Criteo Corp., a wholly owned subsidiary of Criteo S.A., entered into an Agreement and Plan of Merger Agreement with TBL Holdings, Inc. ("TBL Holdings"), a wholly-owned subsidiary of Criteo Corp., HookLogic, Inc.

The determination of the fair value of assets acquired and liabilities assumed will be performed within the twelve months following the acquisition date. The Company evaluated all other subsequent events that occurred after September 30, 2016 through the date of issuance of the unaudited condensed consolidated financial statements and determined that there are no other significant events that require adjustments or disclosure.

Summary of Significant Accoun23

Summary of Significant Accounting Policies (Policies)	9 Months Ended
	Sep. 30, 2016
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The unaudited condensed consolidated financial statements included herein have been prepared by Criteo S.A. pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC"). Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP") have been condensed or omitted pursuant to such rules and regulations. However, the Company believes that the disclosures are adequate to make the information presented not misleading. These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto included in the Company's Annual Report filed on Form 10-K for the year ended December 31, 2015 , filed with the SEC on February 29, 2016. The unaudited condensed consolidated financial statements included herein reflect all adjustments (consisting of normal, recurring adjustments) which are, in the opinion of management, necessary to state fairly the results for the interim periods presented. The results of operations for the interim periods presented are not necessarily indicative of the operating results to be expected for any subsequent interim period or for the fiscal year.
Use of Estimates	Conformity with U.S. GAAP requires the use of estimates and judgments that affect the reported amounts of assets, liabilities, revenue and expenses in the condensed consolidated financial statements and accompanying notes. We base our estimates and judgments on historical information and on various other assumptions that we believe are reasonable under the circumstances. Our actual results may differ from these estimates. U.S. GAAP requires us to make estimates and judgments in several areas, including, but not limited to: (1) the recognition of revenue; (2) the evaluation of our trade receivables and the recognition of a valuation allowance; (3) the recognition and measurement of goodwill and intangible assets and particularly costs capitalized in relation to our customized internal-use software; (4) the measurement of share-based compensation and (5) the tax provision determination and particularly the estimate of our annual effective tax rate.
Recently Issued Accounting Standards	Recently Issued Accounting Standards In September 2015, the FASB issued ASU 2015-16 , Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments . ASU 2015-16 requires an acquirer to recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined, including the cumulative effect of the change in provisional amount, as if the accounting had been completed at the acquisition date. The Company does not expect the provision of ASU 2015-16 to have a material impact on its consolidated financial statements. This update will be effective for fiscal years beginning after December 15, 2016, and interim periods within fiscal years beginning after December 15, 2017. Early adoption is permitted for financial statements that have not yet been made available for issuance. In January 2016, the FASB issued ASU 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities . ASU 2016-01 requires that all financial assets and liabilities not accounted for under the equity method be measured at fair value, with the changes in fair value recognized in net income. The amendments in this update also require an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments. In addition, the amendments in this update supersede the requirement to disclose the methods and significant assumptions used in calculating the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet for public business entities. The Company can early adopt the provision requiring it to recognize in other comprehensive income the fair value change from instrument-specific credit risk measured using the fair value option for financial instruments. Except for this early application guidance, early adoption is not permitted. The Company is still evaluating the effects that the provision of ASU 2016-01 will have on its consolidated financial statements. This update will be effective for fiscal years beginning after December 15, 2018, and interim periods within fiscal years beginning after December 15, 2019. Early adoption as of fiscal years beginning after December 15, 2017, including interim periods within those fiscal year, is permitted. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) . ASU 2016-02 requires an entity to recognize a right-of-use asset and lease liability for all leases with terms of more than 12 months. Recognition, measurement and presentation of expenses will depend on classification as a finance or operating lease. The amendments also require certain quantitative and qualitative disclosures about leasing arrangements. Early adoption is permitted. The updated guidance requires a modified retrospective adoption. The Company is still evaluating the effects that the provision of ASU 2016-02 will have on its consolidated financial statements. This update will be effective for fiscal years beginning after December 15, 2019, and interim periods within fiscal years beginning after December 15, 2020. Early application is permitted. In March 2016, the FASB issued ASU 2016-08, Principal Versus Agent Considerations (Reporting Revenue Gross Versus Net) . ASU 2016-08 amends the principal-versus-agent implementation guidance and illustrations in the FASB's new revenue standard Revenue from Contracts with Customers (ASC Topic 606) . The Company is currently evaluating the impact of ASU 2016-08 on its consolidated financial statements. This update will be effective for fiscal years beginning after December 15, 2018, and interim periods within annual reporting periods beginning after December 15, 2019. Earlier application is permitted only as of fiscal years beginning after December 15, 2016, including interim periods within that fiscal year, or fiscal years beginning after December 15, 2016, and interim periods within fiscal years beginning one year after the fiscal year in which an entity first applies the guidance in Update 2014-09. In March 2016 the FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting . ASU 2016-09 was issued as part of FASB’s initiative to reduce complexity in accounting standards. The areas for simplification in this update involve several aspects of the accounting for employee share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. This update will be effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods. Early adoption is permitted in any interim or annual period. In April 2016 the FASB issued ASU 2016-10, Identifying Performance Obligations and Licensing . ASU 2016-10 clarifies guidance related to identifying performance obligations and licensing implementation guidance contained in the new revenue standard Revenue from Contracts with Customers (ASC Topic 606) . The Company is currently evaluating the impact of ASU 2016-10 on its consolidated financial statements. The effective date of ASU 2016-10 is the same as for requirements of ASC Topic 606. In May 2016 the FASB issued ASU 2016-11, Rescission of SEC Guidance Because of Accounting Standards Updates 2015-09 and 2014-06 Pursuant to Staff Announcements at the March 3, 2016 EITF Meeting (SEC Update). ASU 2016-11 rescinds certain SEC Staff Guidance relating to ASC topics 605 (Revenue Recognition), 932 (Extractive Activities - Oil and Gas), and 815 (Derivatives and Hedging). The ASU became effective immediately. The Company has evaluated the rescinded SEC Staff Guidance and determined it does not have an impact on the consolidated financial statements. In May 2016 the FASB issued ASU 2016-12, Narrow Scope Improvements and Practical Expedients. ASU 2016 - 12 amends narrow aspects of the new revenue standard Revenue from Contracts with Customers (ASC Topic 606) including guidance on assessing collectability, presentation of sales taxes, noncash consideration, and completed contracts and contract modifications at transition. The Company is currently evaluating the impact of ASU 2016-12 on its consolidated financial statements. The effective date of ASU 2016-12 is the same as for requirements of ASC Topic 606. In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326) Measurement of Credit Losses on Financial Statements . ASU 2016-13 amends the guidance on the impairment of financial instruments. Under the new guidance, an entity recognizes as an allowance its estimate of expected credit losses rather than incurred credit losses. In addition, this amendment broadens the information an entity must consider in developing its expected credit loss estimate including the use of forecasts in order to ensure more timely information is used to develop the estimate. The Company is currently evaluating the impact of ASU 2016-13 on its consolidated financial statements. This update will be effective for fiscal years beginning after December 15, 2020, including interim periods within that fiscal year. In August 2016, the FASB issued ASU 2016-14, Not-for-Profit Entities (Topic 958) Presentation of Financial Statements of Not-for-Profit Entities. As this ASU relates to not-for-profit entities only, it is not applicable to Criteo and it does not have an impact on the consolidated financial statements. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230) Classification of Certain Cash Receipts and Cash Payments. ASU 2016-15 amends current U.S. GAAP by adding specific guidance on eight cash flows issues in order to eliminate the current diversity in reporting practices. The eight issues addressed include debt prepayment or debt extinguishment costs, settlement of zero-coupon debt instruments or other debt instruments with coupon interest rates that are insignificant in relation to the effective interest rate of the borrowing, contingent consideration payments made after a business combination, proceeds from the settlement of insurance claims, proceeds from the settlement of corporate owned life insurance policies, distributions received from equity method investees, beneficial interests in securitization transactions and separately identifiable cash flows and application of the predominance principle. The Company is currently evaluating the impact of ASU 2016-15 on its consolidated financial statements. This update will be effective for fiscal years beginning after December 15, 2018, and interim periods beginning after December 15, 2019. Early adoption is permitted in any interim or annual period.
