Accounting Policies [Abstract]
Ownership, Description of Business, and Summary of Significant Accounting Policies	Ownership, Description of Business, and Summary of Significant Accounting Policies Encore Capital Group, Inc. (“Encore”), through its subsidiaries (collectively with Encore, the “Company”), is an international specialty finance company providing debt recovery solutions for consumers across a broad range of financial assets. The Company purchases portfolios of defaulted consumer receivables at deep discounts to face value and manages them by working with individuals as they repay their obligations and work toward financial recovery. Defaulted receivables are consumers’ unpaid financial commitments to credit originators, including banks, credit unions, consumer finance companies, commercial retailers, and telecommunication companies. Defaulted receivables may also include receivables subject to bankruptcy proceedings. Financial Statement Preparation and Presentation The accompanying interim condensed consolidated financial statements have been prepared by the Company, without audit, in accordance with the instructions to the Quarterly Report on Form 10-Q, and Rule 10-01 of Regulation S-X promulgated by the United States Securities and Exchange Commission (the “SEC”) and, therefore, do not include all information and footnotes necessary for a fair presentation of its consolidated financial position, results of operations and cash flows in accordance with accounting principles generally accepted in the United States (“GAAP”). In the opinion of management, the unaudited financial information for the interim periods presented reflects all adjustments, consisting of only normal and recurring adjustments, necessary for a fair presentation of the Company’s consolidated financial position, results of operations, and cash flows. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2015. Operating results for interim periods are not necessarily indicative of operating results for an entire fiscal year. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts and the disclosure of contingent amounts in the Company’s financial statements and the accompanying notes. Actual results could materially differ from those estimates. Basis of Consolidation The condensed consolidated financial statements have been prepared in conformity with GAAP, and reflect the accounts and operations of the Company and those of its subsidiaries in which the Company has a controlling financial interest. The Company also consolidates VIEs, for which it is the primary beneficiary. The primary beneficiary has both (a) the power to direct the activities of the VIE that most significantly affect the entity’s economic performance, and (b) either the obligation to absorb losses or the right to receive benefits. Refer to Note 11, “Variable Interest Entity,” for further details. All intercompany transactions and balances have been eliminated in consolidation. Translation of Foreign Currencies The financial statements of certain of the Company’s foreign subsidiaries are measured using their local currency as the functional currency. Assets and liabilities of foreign operations are translated into U.S. dollars using period-end exchange rates, and revenues and expenses are translated into U.S. dollars using average exchange rates in effect during each period. The resulting translation adjustments are recorded as a component of other comprehensive income or loss. Equity accounts are translated at historical rates, except for the change in retained earnings during the year which is the result of the income statement translation process. Intercompany transaction gains or losses at each period end arising from subsequent measurement of balances for which settlement is not planned or anticipated in the foreseeable future are included as translation adjustments and recorded within other comprehensive income or loss. Transaction gains and losses are included in other income or expense. Reclassifications Certain immaterial reclassifications have been made to the condensed consolidated financial statements to conform to the current year’s presentation. Recent Accounting Pronouncements In June 2016, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) No. 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” (ASU 2016-13). ASU 2016-13 applies a current expected credit loss model which is a new impairment model based on expected losses rather than incurred losses. Under this model, an entity would recognize an impairment allowance equal to its current estimate of all contractual cash flows that the entity does not expect to collect from financial assets measured at amortized cost. The estimate of expected credit losses should consider historical information, current information, as well as reasonable and supportable forecasts, including estimates of prepayments. The expected credit losses, and subsequent adjustments to such losses, will be recorded through an allowance account that is deducted from the amortized cost basis of the financial asset, with the net carrying value of the financial asset presented on the consolidated balance sheet at the amount expected to be collected. Most importantly, the standard eliminates current accounting model for loans and debt securities acquired with deteriorated credit quality, which provides authoritative guidance for the accounting of the Company’s investment in receivable portfolios. Under this new standard, entities will gross up the initial amortized cost for the purchased financial assets with credit deterioration, the initial amortized cost will be the sum of (1) the purchase price and (2) the estimate of credit losses as of the date of acquisition. ASU 2016-13 is effective for reporting periods beginning after December 15, 2019 with early adoption permitted for reporting periods beginning after December 15, 2018. The Company is currently assessing the impact that adopting this guidance will have on its consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-09, “Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting” (“ASU 2016-09”). ASU 2016-09 simplifies several aspects of the accounting for 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. For public entities, ASU 2016-09 is effective for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. Early adoption is permitted. The Company is currently assessing the impact that adopting this guidance will have on its consolidated financial statements. In March 2016, the FASB issued ASU 2016-05, Derivatives and Hedging (Topic 815): Effect of Derivative Contract Novations on Existing Hedge Accounting Relationships (“ASU 2016-05”) and ASU 2016-06, Derivatives and Hedging (Topic 815): Contingent Put and Call Options in Debt Instruments (“ASU 2016-06”). ASU 2016-05 clarifies that a change in the counterparty to a derivative instrument that has been designated as a hedging instrument does not, in and of itself, require dedesignation of that hedging relationship provided that all other hedge accounting criteria continue to be met. ASU 2016-06 clarifies the steps required to determine bifurcation of an embedded derivative. ASU 2016-05 and ASU 2016-06 are effective for fiscal years beginning after December 15, 2016, and interim periods within those years. Early adoption is permitted. The Company is currently assessing the impact that adopting this guidance will have on its consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) (“ASU 2016-02”). ASU 2016-02 changes accounting for leases and requires lessees to recognize the assets and liabilities arising from all leases, including those classified as operating leases under previous accounting guidance, on the balance sheet and requires disclosure of key information about leasing arrangements to increase transparency and comparability among organizations. ASU 2016-02 is effective for the Company in its first quarter of fiscal 2019 on a modified retrospective basis and earlier adoption is permitted. The Company is currently assessing the impact that adopting this guidance will have on its consolidated financial statements. Change in Accounting Principle In April 2015, the FASB issued ASU No. 2015-03, Interest—Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Cost (“ASU 2015-03”). ASU 2015-03 requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. ASU 2015-03 was effective beginning January 1, 2016, with early adoption permitted. The update requires retrospective application and represents a change in accounting principle. The Company adopted ASU 2015-03 in the first quarter of 2016 and the retrospective application of this change in accounting principle on the consolidated balance sheet as of December 31, 2015 reclassified debt issuance costs of $41.7 million, which were previously presented as other assets, as a reduction to the carrying value of the debt by the same amount. The adoption did not have an impact on the Company's condensed consolidated statements of operations or statements of cash flows in any period.
