Significant Accounting Policies (Policies)	3 Months Ended
Mar. 31, 2019
Accounting Policies [Abstract]
Basis of Presentation	The accompanying consolidated balance sheet as of December 31, 2018, which is derived from audited financial statements, and the unaudited 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. These unaudited consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and with the rules and regulations for reporting on Form 10-Q. Accordingly, they do not include certain information and disclosures required for comprehensive 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, 2018, filed with the Securities and Exchange Commission (the “SEC”) on February 5, 2019. The consolidated financial statements as of March 31, 2019 and 2018, and for the three month periods ended March 31, 2019 and 2018, 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, 2019 are not necessarily indicative of the results that may be expected for the full 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, 2019 and 2018. The Company also has operations in El Salvador where the reporting and functional currency is the U.S. dollar.
Recent Accounting Pronouncements	On January 1, 2019, the Financial Accounting Standards Board’s lease accounting standard (“ASC 842”) became effective requiring lessees to recognize, in the statement of financial position, a liability for the present value of future minimum lease payments (the lease liability) and an asset representing its right to use the underlying leased property for the lease term (the right of use “ROU” asset). 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. ASC 842 provides for a modified retrospective transition approach, which requires lessees to recognize and measure leases on the balance sheet at the beginning of the earliest period presented, or a cumulative effect adjustment transition approach, which requires prospective application from the adoption date. The Company adopted ASC 842 prospectively as of January 1, 2019 using the cumulative effect adjustment approach. As a result of the transition method used, ASC 842 was not applied to periods prior to adoption and the adoption of ASC 842 had no impact on the Company’s comparative prior periods presented. ASC 842 provides a number of optional practical expedients in transition. The Company elected the package of practical expedients, which permit it to not reassess under the new standard its prior conclusions about lease identification, lease classification and initial direct costs but did not elect any other practical expedient available under ASC 842. The adoption of ASC 842 resulted in a material increase in the assets and liabilities reflected on the Company’s consolidated balance sheets, but did not have a material impact on its consolidated statements of income or consolidated statements of cash flows. See Note 4. 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. In November 2018, the Financial Accounting Standards Board issued ASU No. 2018-19, “Codification Improvements to Topic 326, Financial Instruments - Credit Losses” (“ASU 2018-19”) which clarifies that receivables arising from operating leases are accounted for using lease guidance and not as financial instruments. ASU 2016-13 and ASU 2018-19 are 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 and ASU 2018-19 on its consolidated financial statements. 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”), which eliminates step 2 from the goodwill impairment test. ASU 2017-04 also eliminates 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 June 2018, the Financial Accounting Standards Board issued ASU No. 2018-07, “Compensation-Stock Compensation (Topic 718) - Improvements to Nonemployee Share-Based Payment Accounting” (“ASU 2018-07”). ASU 2018-07 simplifies the accounting for nonemployee share-based payment transactions. The amendments specify that Topic 718 applies to all share-based payment transactions in which a grantor acquires goods or services to be used or consumed in a grantor’s own operations by issuing share-based payment awards. ASU 2018-07 is effective for public entities for fiscal years beginning after December 15, 2018. The adoption of ASU 2018-07 did not have a material effect on the Company’s current financial position, results of operations or financial statement disclosures. In July 2018, the Financial Accounting Standards Board issued ASU No. 2018-09, “Codification Improvements” (“ASU 2018-09”). ASU 2018-09 does not prescribe any new accounting guidance, but instead makes minor improvements and clarifications of several different Financial Accounting Standards Board Accounting Standards Codification areas based on comments and suggestions made by various stakeholders. Certain updates are applicable immediately while others provide for a transition period to adopt in fiscal years beginning after December 15, 2018. The adoption of ASU 2018-09 did not have a material effect on the Company’s current financial position, results of operations or financial statement disclosures. In August 2018, the Financial Accounting Standards Board issued ASU No. 2018-13, “Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement” (“ASU 2018-13”). ASU 2018-13 modifies the disclosure requirements on fair value measurements. ASU 2018-13 is effective for public entities for fiscal years beginning after December 15, 2019, with early adoption permitted for any removed or modified disclosures. The removed and modified disclosures will be adopted on a retrospective basis and the new disclosures will be adopted on a prospective basis. The Company does not expect ASU 2018-13 to have a material effect on the Company’s current financial position, results of operations or financial statement disclosures.
Fair Value Measurement	The fair value of financial instruments is determined by reference to various market data and other valuation techniques, as appropriate. Financial assets and liabilities are classified based on the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement requires judgment, and may affect the valuation of the fair value of assets and liabilities and their placement within the fair value hierarchy levels. The three fair value levels are (from highest to lowest): Level 1: Quoted market prices in active markets for identical assets or liabilities. Level 2: Observable market-based inputs or unobservable inputs that are corroborated by market data. Level 3: Unobservable inputs that are not corroborated by market data.
Reclassifications	oss on foreign exchange of $0.2 million for the three months ended March 31, 2018 was reclassified on the consolidated statements of income in order to conform with the presentation for the three months ended March 31, 2019. The loss on foreign exchange was reclassified from store operating expenses and reported separately on the consolidated statements of income. Purchases of store real property of $3.4 million for the three months ended March 31, 2018 were reclassified on the consolidated statements of cash flows in order to conform with the presentation for the three months ended March 31, 2019. Purchases of store real property were reclassified from purchases of furniture, fixtures, equipment and improvements and reported separately on the consolidated statements of cash flows. As a result, purchases of furniture, fixtures, equipment and improvements include expenditures for improvements to existing stores, de novo store openings and corporate assets, and excludes discretionary store real property purchases.

Significant Accounting Policies (Policies)

3 Months Ended

Mar. 31, 2019

The accompanying consolidated balance sheet as of December 31, 2018, which is derived from audited financial statements, and the unaudited 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.

These unaudited consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and with the rules and regulations for reporting on Form 10-Q. Accordingly, they do not include certain information and disclosures required for comprehensive 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, 2018, filed with the Securities and Exchange Commission (the “SEC”) on February 5, 2019. The consolidated financial statements as of March 31, 2019 and 2018, and for the three month periods ended March 31, 2019 and 2018, 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, 2019 are not necessarily indicative of the results that may be expected for the full 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, 2019 and 2018. The Company also has operations in El Salvador where the reporting and functional currency is the U.S. dollar.

Recent Accounting Pronouncements

On January 1, 2019, the Financial Accounting Standards Board’s lease accounting standard (“ASC 842”) became effective requiring lessees to recognize, in the statement of financial position, a liability for the present value of future minimum lease payments (the lease liability) and an asset representing its right to use the underlying leased property for the lease term (the right of use “ROU” asset). 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. ASC 842 provides for a modified retrospective transition approach, which requires lessees to recognize and measure leases on the balance sheet at the beginning of the earliest period presented, or a cumulative effect adjustment transition approach, which requires prospective application from the adoption date. The Company adopted ASC 842 prospectively as of January 1, 2019 using the cumulative effect adjustment approach. As a result of the transition method used, ASC 842 was not applied to periods prior to adoption and the adoption of ASC 842 had no impact on the Company’s comparative prior periods presented.

ASC 842 provides a number of optional practical expedients in transition. The Company elected the package of practical expedients, which permit it to not reassess under the new standard its prior conclusions about lease identification, lease classification and initial direct costs but did not elect any other practical expedient available under ASC 842.

The adoption of ASC 842 resulted in a material increase in the assets and liabilities reflected on the Company’s consolidated balance sheets, but did not have a material impact on its consolidated statements of income or consolidated statements of cash flows. See Note 4.

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. In November 2018, the Financial Accounting Standards Board issued ASU No. 2018-19, “Codification Improvements to Topic 326, Financial Instruments - Credit Losses” (“ASU 2018-19”) which clarifies that receivables arising from operating leases are accounted for using lease guidance and not as financial instruments. ASU 2016-13 and ASU 2018-19 are 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 and ASU 2018-19 on its consolidated financial statements.

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”), which eliminates step 2 from the goodwill impairment test. ASU 2017-04 also eliminates 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 June 2018, the Financial Accounting Standards Board issued ASU No. 2018-07, “Compensation-Stock Compensation (Topic 718) - Improvements to Nonemployee Share-Based Payment Accounting” (“ASU 2018-07”). ASU 2018-07 simplifies the accounting for nonemployee share-based payment transactions. The amendments specify that Topic 718 applies to all share-based payment transactions in which a grantor acquires goods or services to be used or consumed in a grantor’s own operations by issuing share-based payment awards. ASU 2018-07 is effective for public entities for fiscal years beginning after December 15, 2018. The adoption of ASU 2018-07 did not have a material effect on the Company’s current financial position, results of operations or financial statement disclosures.

In July 2018, the Financial Accounting Standards Board issued ASU No. 2018-09, “Codification Improvements” (“ASU 2018-09”). ASU 2018-09 does not prescribe any new accounting guidance, but instead makes minor improvements and clarifications of several different Financial Accounting Standards Board Accounting Standards Codification areas based on comments and suggestions made by various stakeholders. Certain updates are applicable immediately while others provide for a transition period to adopt in fiscal years beginning after December 15, 2018. The adoption of ASU 2018-09 did not have a material effect on the Company’s current financial position, results of operations or financial statement disclosures.

In August 2018, the Financial Accounting Standards Board issued ASU No. 2018-13, “Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement” (“ASU 2018-13”). ASU 2018-13 modifies the disclosure requirements on fair value measurements. ASU 2018-13 is effective for public entities for fiscal years beginning after December 15, 2019, with early adoption permitted for any removed or modified disclosures. The removed and modified disclosures will be adopted on a retrospective basis and the new disclosures will be adopted on a prospective basis. The Company does not expect ASU 2018-13 to have a material effect on the Company’s current financial position, results of operations or financial statement disclosures.

Fair Value Measurement

The fair value of financial instruments is determined by reference to various market data and other valuation techniques, as appropriate. Financial assets and liabilities are classified based on the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement requires judgment, and may affect the valuation of the fair value of assets and liabilities and their placement within the fair value hierarchy levels. The three fair value levels are (from highest to lowest):

Level 1: Quoted market prices in active markets for identical assets or liabilities.

Level 2: Observable market-based inputs or unobservable inputs that are corroborated by market data.

Level 3: Unobservable inputs that are not corroborated by market data.

Reclassifications

oss on foreign exchange of $0.2 million for the three months ended March 31, 2018 was reclassified on the consolidated statements of income in order to conform with the presentation for the three months ended March 31, 2019. The loss on foreign exchange was reclassified from store operating expenses and reported separately on the consolidated statements of income.

Purchases of store real property of $3.4 million for the three months ended March 31, 2018 were reclassified on the consolidated statements of cash flows in order to conform with the presentation for the three months ended March 31, 2019. Purchases of store real property were reclassified from purchases of furniture, fixtures, equipment and improvements and reported separately on the consolidated statements of cash flows. As a result, purchases of furniture, fixtures, equipment and improvements include expenditures for improvements to existing stores, de novo store openings and corporate assets, and excludes discretionary store real property purchases.
