Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies Basis of Presentation The accompanying condensed consolidated balance sheet at December 31, 2017, which is derived from audited financial statements, and the unaudited condensed consolidated financial statements, including the notes thereto, include the accounts of FirstCash, Inc. and its wholly-owned subsidiaries (together, the “Company”). The Company regularly makes acquisitions and the results of operations for the acquired stores have been consolidated since the acquisition dates. All significant intercompany accounts and transactions have been eliminated. See Note 3. These unaudited consolidated financial statements are condensed and do not include all disclosures and footnotes required by generally accepted accounting principles in the United States of America for complete financial statements. These interim period financial statements should be read in conjunction with the Company’s consolidated financial statements, which are included in the Company’s annual report on Form 10-K for the year ended December 31, 2017, filed with the Securities and Exchange Commission (the “SEC”) on February 20, 2018. The condensed consolidated financial statements as of March 31, 2018 and 2017, and for the three month periods ended March 31, 2018 and 2017, are unaudited, but in management’s opinion include all adjustments (consisting of only normal recurring adjustments) considered necessary to present fairly the financial position, results of operations and cash flow for such interim periods. Operating results for the period ended March 31, 2018 are not necessarily indicative of the results that may be expected for the full fiscal year. The Company has significant operations in Latin America, where in Mexico, Guatemala and Colombia the functional currency is the Mexican peso, Guatemalan quetzal and Colombian peso, respectively. Accordingly, the assets and liabilities of these subsidiaries are translated into U.S. dollars at the exchange rate in effect at each balance sheet date, and the resulting adjustments are accumulated in other comprehensive income (loss) as a separate component of stockholders’ equity. Revenues and expenses are translated at the average exchange rates occurring during the three month periods ended March 31, 2018 and 2017. The Company also has operations in El Salvador where the reporting and functional currency is the U.S. dollar. Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board issued ASU No. 2014-09, “Revenue from Contracts with Customers (Topic 606)” (“ASU 2014-09”). ASU 2014-09 is a comprehensive revenue recognition model that requires a company to recognize revenue to depict the transfer of goods or services to a customer at an amount that reflects the consideration it expects to receive in exchange for those goods or services. ASU 2014-09 also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. In August 2015, the Financial Accounting Standards Board issued ASU No. 2015-14, “Revenue from Contracts with Customers (Topic 606),” which delayed the effective date of ASU 2014-09 by one year. In addition, between March 2016 and December 2016, the Financial Accounting Standards Board issued ASU No. 2016-08, “Revenue from Contracts with Customers - Principal versus Agent Considerations (Reporting revenue gross versus net)” (“ASU 2016-08”), ASU No. 2016-10, “Identifying Performance Obligations and Licensing” (“ASU 2016-10”), ASU No. 2016-12, “Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients” (“ASU 2016-12”), and ASU No. 2016-20, “Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers” (“ASU 2016-20”). ASU 2016-08, ASU 2016-10, ASU 2016-12 and ASU 2016-20 clarify certain aspects of ASU 2014-09 and provide additional implementation guidance. ASU 2014-09, ASU 2016-08, ASU 2016-10, ASU 2016-12 and ASU 2016-20 (collectively, “ASC 606”) became effective for annual reporting periods (including interim periods within those periods) beginning after December 15, 2017 for public companies. Entities are permitted to adopt ASC 606 using one of two methods: (a) full retrospective adoption, meaning the standard is applied to all periods presented, or (b) modified retrospective adoption, meaning the cumulative effect of applying the new standard is recognized as an adjustment to the opening retained earnings balance. The Company adopted ASC 606 as of January 1, 2018 using the modified retrospective method. The adoption of ASC 606 did not impact the Company’s revenue recognition for pawn loan fees, consumer loan fees, or credit services fees, as each of these revenue streams is outside of the scope of ASC 606. Further, the Company has not identified any impacts to its consolidated financial statements that were material as a result of the adoption of ASC 606 for its retail merchandise sales or wholesale scrap jewelry sales revenue streams. The Company has not changed the presentation of its consolidated financial statements for assets, liabilities, or revenues from contracts with customers, nor has the Company recognized any cumulative effect adjustment as a result of the adoption of ASC 606. In February 2016, the Financial Accounting Standards Board issued ASU No. 2016-02, “Leases (Topic 842)” (“ASU 2016-02”). ASU 2016-02 requires a lessee to recognize, in the statement of financial position, a liability to make lease payments (the lease liability) and a right-to-use asset representing its right to use the underlying asset for the lease term. Leases will be classified as either financing or operating, with classification affecting the pattern of expense recognition in the income statement. Lessor accounting remains largely unchanged. ASU 2016-02 is effective for annual reporting periods beginning after December 15, 2018, and interim periods within those annual periods, with early adoption permitted. An entity will be required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. The Company is currently assessing the potential impact of ASU 2016-02 on its consolidated financial statements. In June 2016, the Financial Accounting Standards Board issued ASU No. 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” (“ASU 2016-13”). ASU 2016-13 amends the impairment model by requiring entities to use a forward-looking approach based on expected losses to estimate credit losses on certain types of financial instruments, including trade receivables. ASU 2016-13 is effective for public entities for fiscal years beginning after December 15, 2019, with early adoption permitted. The Company is currently assessing the potential impact of ASU 2016-13 on its consolidated financial statements. In August 2016, the Financial Accounting Standards Board issued ASU No. 2016-15, “Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments” (“ASU 2016-15”). ASU 2016-15 clarifies how companies present and classify certain cash receipts and cash payments in the statement of cash flows. ASU 2016-15 addresses eight specific cash flow issues with the objective of reducing existing diversity in practice. ASU 2016-15 became effective for public entities for fiscal years beginning after December 15, 2017. The adoption of ASU 2016-15 did not have a material effect on the Company’s consolidated financial statements or financial statement disclosures. In January 2017, the Financial Accounting Standards Board issued ASU No. 2017-01, “Business Combinations (Topic 805) - Clarifying the Definition of a Business” (“ASU 2017-01”). ASU 2017-01 provides amendments to clarify the definition of a business and affects all companies and other reporting organizations that must determine whether they have acquired or sold a business. The amendments are intended to help companies and other organizations evaluate whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The guidance became effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years and should be applied prospectively as of the beginning of the period of adoption. The adoption of ASU 2017-01 did not have a material effect on the Company’s current financial position, results of operations or financial statement disclosures. In January 2017, the Financial Accounting Standards Board issued ASU No. 2017-04, “Intangibles - Goodwill and Other (Topic 350) - Simplifying the Test for Goodwill Impairment” (“ASU 2017-04”). These amendments eliminate step 2 from the goodwill impairment test. The amendments also eliminate the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment and, if it fails that qualitative test, to perform step 2 of the goodwill impairment test. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. The guidance is effective for annual or any interim goodwill impairment 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 and should be adopted on a prospective basis. The Company does not expect ASU 2017-04 to have a material effect on the Company’s current financial position, results of operations or financial statement disclosures. In March 2018, the Financial Accounting Standards Board issued ASU No 2018-05, “Income Taxes (Topic 740): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118” (“ASU 2018-05”), which became effective immediately. ASU 2018-05 adds various SEC paragraphs pursuant to the issuance of the December 2017 SEC Staff Accounting Bulletin No. 118, Income Tax Accounting Implications of the Tax Cuts and Jobs Act (“SAB 118”). See Note 6 for additional information regarding the adoption of ASU 2018-05.
