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 and other related services 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. The Company is a market leader in portfolio purchasing and recovery in the United States, including Puerto Rico. Cabot Credit Management plc (together with its subsidiaries, “Cabot”), the Company’s largest international subsidiary, is one of the largest credit management services providers in Europe and is a market leader in the United Kingdom and Ireland. Previously, Encore controlled Cabot via its majority ownership interest in the indirect holding company of Cabot, Janus Holdings S.a r.l. (“Janus Holdings”). On July 24, 2018, the Company completed the purchase of all of the outstanding equity of Cabot not owned by the Company (the “Cabot Transaction”). As a result, Cabot became a wholly owned subsidiary of Encore. These are the Company’s primary operations. 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, 2017. 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 9, “Variable Interest Entities,” 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. Translation gains or losses are the material components of accumulated 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. Change in Accounting Principle In May 2014, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers (“Topic 606” or “ASU 2014-09”). The objective of ASU 2014-09 is to establish a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers. ASU 2014-09 supersedes most of the existing revenue recognition guidance, including industry-specific guidance. The core principle is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 applies to all contracts with customers except those that are within the scope of other topics in the FASB’s Accounting Standards Codification (“ASC”). Under the prior accounting standard, the Company recognized revenue when there was persuasive evidence of an arrangement, the sales price was fixed or determinable, the services had been performed and collectability was reasonably assured. The Company’s investment in receivable portfolios is outside of the scope of Topic 606 since it is accounted for in accordance with ASC 310-30. Certain of the Company’s international subsidiaries earn fee-based income by providing portfolio management services to credit originators for non-performing loans. Performance obligations for this revenue stream under the new standard primarily arise from debt collection and management activities. These performance obligations are typically satisfied when services are performed, or debt is collected. Consideration is typically variable based on indeterminate volumes or collection activity. Under the new accounting standard, revenue is recognized over time as a series of single performance obligations when the Company is entitled to a percentage of collections received, since the customer simultaneously receives and consumes the benefits provided by the Company’s performance of debt collection and management. The method for measuring progress towards satisfying a performance obligation is based on transaction volumes or debt collected, depending on whether the contract is based on services performed or based on commissions. Costs to fulfill a contract are expensed when incurred. The Company adopted the requirements of Topic 606 as of January 1, 2018, utilizing the modified retrospective method of transition and elected to apply the revenue standard only to contracts that were not completed as of the adoption date. Prior periods were not restated. The cumulative effect of adopting this new standard had no impact to retained earnings. The impact of adopting Topic 606 on the Company’s revenue is not material to any of the periods presented. Fee-based income is included in “Other Revenues” in the Company’s consolidated statements of operations. In August 2017, the FASB issued ASU 2017-12, Targeted Improvements to Accounting for Hedging Activities—Derivatives and Hedging (“Topic 815” or “ASU 2017-12”) which amends the hedge accounting recognition and presentation requirements in ASC 815. ASU 2017-12 improves Topic 815 by simplifying and expanding the eligible hedging strategies for financial and nonfinancial risks by more closely aligning hedge accounting with a company’s risk management activities, and also simplifies its application through targeted improvements in key practice areas. This includes expanding the list of items eligible to be hedged and amending the methods used to measure the effectiveness of hedging relationships. In addition, ASU 2017-12 prescribes how hedging results should be presented and requires incremental disclosures. These changes are intended to allow preparers more flexibility and to enhance the transparency of how hedging results are presented and disclosed. Further, the new standard provides partial relief on the timing of certain aspects of hedge documentation and eliminates the requirement to recognize hedge ineffectiveness separately in earnings in the current period. For public entities, ASU 2017-12 is effective for fiscal years, including interim periods within those fiscal years, beginning after December 15, 2018, with early adoption permitted in any interim period or fiscal year. The Company early adopted ASU 2017-12 as of the second quarter of 2018 retroactive to January 1, 2018. The adoption of the new standard did not have a material effect on the Company’s financial position, results of operations, or required presentations. Recent Accounting Pronouncements Other than the adoption of the standards discussed above, there have been no new accounting pronouncements made effective during the three and six months ended June 30, 2018 that have significance, or potential significance, to the Company’s consolidated financial statements. Recent Accounting Pronouncements Not Yet Effective In January 2017, the FASB issued ASU 2017-04, Intangibles - Goodwill and Other (Topic 350). The amendments in this update simplify the test for goodwill impairment by eliminating Step 2 from the impairment test, which required the entity to perform procedures to determine the fair value at the impairment testing date of its assets and liabilities following the procedure that would be required in determining fair value of assets acquired and liabilities assumed in a business combination. The amendments in this update are effective for public companies for annual or any interim goodwill impairments tests in fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company did not early adopt this guidance for its annual goodwill impairment testing. In June 2016, the FASB issued 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. ASU 2016-13 eliminates the current accounting model for loans and debt securities acquired with deteriorated credit quality under ASC 310-30, 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 (“PCD assets”), 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. After initial recognition of PCD assets and the related allowance, any change in estimated cash flows (favorable or unfavorable) will be immediately recognized in the income statement because the yield on PCD assets would be locked. 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 guidance will be applied on a modified retrospective basis through a cumulative-effect adjustment to retained earnings as of the beginning of the period in which ASU 2016-13 is adopted. However, the FASB has determined that financial assets for which the guidance in Subtopic 310-30, Receivables-Loans and Debt Securities Acquired with Deteriorated Credit Quality, has previously been applied should prospectively apply the guidance in ASU 2016-13 for PCD assets. A prospective transition approach should be used for PCD assets where upon adoption, the amortized cost basis should be adjusted to reflect the addition of the allowance for credit losses. This transition relief will avoid the need for a reporting entity to reassess its purchased financial assets that exist as of the date of adoption to determine whether they would have met at acquisition the new criteria of more-than insignificant credit deterioration since origination. The transition relief also will allow an entity to accrete the remaining noncredit discount (based on the revised amortized cost basis) into interest income at the effective interest rate at the adoption date of ASU 2016-13. The same transition requirements should be applied to beneficial interests that previously applied Subtopic 310-30 or have a significant difference between contractual cash flows and expected cash flows. The Company is in the process of determining the effects the adoption will have on its consolidated financial statements as well as whether to adopt the new guidance early. The Company has established a project management team and is in the process of developing its accounting policy, evaluating the impact of this pronouncement and researching software resources that could assist with the implementation. 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 most 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. In July 2018, the FASB issued ASU 2018-10, Codification Improvements to Topic 842, which provides narrow amendments to clarify how to apply certain aspects of the new lease standard. The new guidance must be adopted using the modified retrospective approach and will be effective for the Company starting in the first quarter of fiscal year 2019. Early adoption is permitted; however, the Company does not intend to early adopt ASU 2016-02 and ASU 2018-10. The Company is developing an inventory of all leases, accumulating the lease data necessary to apply the amended guidance and is in the process of determining the effects the adoption will have on its consolidated financial statements, systems and processes. The Company has selected a software to assist with implementation to the standard. With the exception of the updated standards discussed above, there have been no new accounting pronouncements not yet effective that have significance, or potential significance, to the Company’s consolidated financial statements.

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 and other related services 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.

The Company is a market leader in portfolio purchasing and recovery in the United States, including Puerto Rico. Cabot Credit Management plc (together with its subsidiaries, “Cabot”), the Company’s largest international subsidiary, is one of the largest credit management services providers in Europe and is a market leader in the United Kingdom and Ireland. Previously, Encore controlled Cabot via its majority ownership interest in the indirect holding company of Cabot, Janus Holdings S.a r.l. (“Janus Holdings”). On July 24, 2018, the Company completed the purchase of all of the outstanding equity of Cabot not owned by the Company (the “Cabot Transaction”). As a result, Cabot became a wholly owned subsidiary of Encore. These are the Company’s primary operations.

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, 2017. 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 9, “Variable Interest Entities,” 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. Translation gains or losses are the material components of accumulated 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.

Change in Accounting Principle

In May 2014, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers (“Topic 606” or “ASU 2014-09”). The objective of ASU 2014-09 is to establish a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers.

ASU 2014-09 applies to all contracts with customers except those that are within the scope of other topics in the FASB’s Accounting Standards Codification (“ASC”). Under the prior accounting standard, the Company recognized revenue when there was persuasive evidence of an arrangement, the sales price was fixed or determinable, the services had been performed and collectability was reasonably assured.

The Company’s investment in receivable portfolios is outside of the scope of Topic 606 since it is accounted for in accordance with ASC 310-30. Certain of the Company’s international subsidiaries earn fee-based income by providing portfolio management services to credit originators for non-performing loans. Performance obligations for this revenue stream under the new standard primarily arise from debt collection and management activities.

Under the new accounting standard, revenue is recognized over time as a series of single performance obligations when the Company is entitled to a percentage of collections received, since the customer simultaneously receives and consumes the benefits provided by the Company’s performance of debt collection and management. The method for measuring progress towards satisfying a performance obligation is based on transaction volumes or debt collected, depending on whether the contract is based on services performed or based on commissions.

The Company adopted the requirements of Topic 606 as of January 1, 2018, utilizing the modified retrospective method of transition and elected to apply the revenue standard only to contracts that were not completed as of the adoption date. Prior periods were not restated. The cumulative effect of adopting this new standard had no impact to retained earnings. The impact of adopting Topic 606 on the Company’s revenue is not material to any of the periods presented. Fee-based income is included in “Other Revenues” in the Company’s consolidated statements of operations.

In August 2017, the FASB issued ASU 2017-12, Targeted Improvements to Accounting for Hedging Activities—Derivatives and Hedging (“Topic 815” or “ASU 2017-12”) which amends the hedge accounting recognition and presentation requirements in ASC 815. ASU 2017-12 improves Topic 815 by simplifying and expanding the eligible hedging strategies for financial and nonfinancial risks by more closely aligning hedge accounting with a company’s risk management activities, and also simplifies its application through targeted improvements in key practice areas. This includes expanding the list of items eligible to be hedged and amending the methods used to measure the effectiveness of hedging relationships. In addition, ASU 2017-12 prescribes how hedging results should be presented and requires incremental disclosures. These changes are intended to allow preparers more flexibility and to enhance the transparency of how hedging results are presented and disclosed. Further, the new standard provides partial relief on the timing of certain aspects of hedge documentation and eliminates the requirement to recognize hedge ineffectiveness separately in earnings in the current period. For public entities, ASU 2017-12 is effective for fiscal years, including interim periods within those fiscal years, beginning after December 15, 2018, with early adoption permitted in any interim period or fiscal year. The Company early adopted ASU 2017-12 as of the second quarter of 2018 retroactive to January 1, 2018. The adoption of the new standard did not have a material effect on the Company’s financial position, results of operations, or required presentations.

Recent Accounting Pronouncements

Other than the adoption of the standards discussed above, there have been no new accounting pronouncements made effective during the three and six months ended June 30, 2018 that have significance, or potential significance, to the Company’s consolidated financial statements.

Recent Accounting Pronouncements Not Yet Effective

In January 2017, the FASB issued ASU 2017-04, Intangibles - Goodwill and Other (Topic 350). The amendments in this update simplify the test for goodwill impairment by eliminating Step 2 from the impairment test, which required the entity to perform procedures to determine the fair value at the impairment testing date of its assets and liabilities following the procedure that would be required in determining fair value of assets acquired and liabilities assumed in a business combination. The amendments in this update are effective for public companies for annual or any interim goodwill impairments tests in fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company did not early adopt this guidance for its annual goodwill impairment testing.

In June 2016, the FASB issued 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. ASU 2016-13 eliminates the current accounting model for loans and debt securities acquired with deteriorated credit quality under ASC 310-30, 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 (“PCD assets”), 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. After initial recognition of PCD assets and the related allowance, any change in estimated cash flows (favorable or unfavorable) will be immediately recognized in the income statement because the yield on PCD assets would be locked. 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 guidance will be applied on a modified retrospective basis through a cumulative-effect adjustment to retained earnings as of the beginning of the period in which ASU 2016-13 is adopted. However, the FASB has determined that financial assets for which the guidance in Subtopic 310-30, Receivables-Loans and Debt Securities Acquired with Deteriorated Credit Quality, has previously been applied should prospectively apply the guidance in ASU 2016-13 for PCD assets. A prospective transition approach should be used for PCD assets where upon adoption, the amortized cost basis should be adjusted to reflect the addition of the allowance for credit losses. This transition relief will avoid the need for a reporting entity to reassess its purchased financial assets that exist as of the date of adoption to determine whether they would have met at acquisition the new criteria of more-than insignificant credit deterioration since origination. The transition relief also will allow an entity to accrete the remaining noncredit discount (based on the revised amortized cost basis) into interest income at the effective interest rate at the adoption date of ASU 2016-13. The same transition requirements should be applied to beneficial interests that previously applied Subtopic 310-30 or have a significant difference between contractual cash flows and expected cash flows. The Company is in the process of determining the effects the adoption will have on its consolidated financial statements as well as whether to adopt the new guidance early. The Company has established a project management team and is in the process of developing its accounting policy, evaluating the impact of this pronouncement and researching software resources that could assist with the implementation.

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 most 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. In July 2018, the FASB issued ASU 2018-10, Codification Improvements to Topic 842, which provides narrow amendments to clarify how to apply certain aspects of the new lease standard. The new guidance must be adopted using the modified retrospective approach and will be effective for the Company starting in the first quarter of fiscal year 2019. Early adoption is permitted; however, the Company does not intend to early adopt ASU 2016-02 and ASU 2018-10. The Company is developing an inventory of all leases, accumulating the lease data necessary to apply the amended guidance and is in the process of determining the effects the adoption will have on its consolidated financial statements, systems and processes. The Company has selected a software to assist with implementation to the standard.

With the exception of the updated standards discussed above, there have been no new accounting pronouncements not yet effective that have significance, or potential significance, to the Company’s consolidated financial statements.
