Accounting Policies [Abstract]
Basis of presentation	Basis of presentation: The consolidated financial statements of the Company have been prepared in accordance with the instructions to the Quarterly Report on Form 10-Q adopted by the Securities and Exchange Commission (“SEC”) and generally accepted accounting principles in the United States of America (“GAAP”) for interim financial information and, accordingly, do not include all information and note disclosures required by GAAP for complete financial statements. The interim financial statements in this Quarterly Report on Form 10-Q have not been audited by an independent registered public accounting firm in accordance with standards of the Public Company Accounting Oversight Board (United States), but in the opinion of management, the interim financial statements include all adjustments, consisting only of normal recurring adjustments, necessary for a fair presentation of the Company’s financial position, results of operations, and cash flows in accordance with GAAP. These consolidated financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2015, as filed with the SEC.
Business segments	*Business segments:* The Company has one reportable segment, which is the consumer finance segment. The other revenue generating activities of the Company, including insurance operations, are performed in the existing branch network in conjunction with or as a complement to the lending operations.
Principles of consolidation	*Principles of consolidation:* The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. The Company operates through a separate wholly-owned subsidiary in each state. The Company also consolidates variable interest entities (“VIE”) when it is considered to be the primary beneficiary of the VIE because it has (i) power over the significant activities of the VIE and (ii) the obligation to absorb losses or the right to receive returns that could be significant to the VIE.
Treasury stock	*Treasury stock:* The Company records the repurchase of shares of its common stock at cost on the settlement date of the transaction. These shares are considered treasury stock, which is a reduction to stockholders’ equity. Treasury stock is included in authorized and issued shares but excluded from outstanding shares.
Variable interest entity	*Variable interest entity:* The Company has an asset-backed amortizing loan for general funding purposes. The transaction involved selling a pool of the Company’s automobile loans to its wholly-owned subsidiary, Regional Management Receivables, LLC (“RMR”), as collateral for the loan. RMR has the limited purpose of acquiring finance receivables and holding and making payments on the related debt. Assets transferred to RMR are legally isolated from the Company and the claims of the Company’s other creditors. The Company continues to service the finance receivables transferred to RMR. The lender in the debt issued by RMR generally only has recourse to the assets of RMR and does not have recourse to the general credit of the Company. The Company’s asset-backed loan under this arrangement is structured to provide enhancements to the lender in the form of overcollateralization (the principal balance of the collateral exceeds the balance of the debt) and reserve funds (restricted cash accounts held by RMR). These enhancements, along with the isolated finance receivables pool, increase the creditworthiness of RMR above that of the Company as a whole. This increases the marketability of the Company’s collateral for borrowing purposes, which leads to more favorable borrowing terms, improved interest rate risk management, and additional flexibility to grow the business. RMR is considered a VIE under GAAP and is consolidated into the financial statements of RMR’s primary beneficiary. The Company is considered to be the primary beneficiary of RMR because it has (i) power over the significant activities of RMR through its role as servicer of the finance receivables under the credit agreement and (ii) the obligation to absorb losses or the right to receive returns that could be significant through the Company’s interest in the monthly residual cash flows of RMR after the debt is paid. Consolidation of RMR results in the transaction being accounted for as a secured borrowing; therefore, the pooled receivables and the related debt remain on the consolidated balance sheet of the Company. The debt is secured solely by the assets of RMR and not by any other assets of the Company. The assets of RMR are the only source of funds for repayment on the debt. Restricted cash accounts held by RMR can only be used to support payments on the debt. The Company recognizes revenue and provision for credit losses on RMR’s finance receivables and interest expense on the related secured debt.
Use of estimates	*Use of estimates:* The preparation of financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, revenues and expenses, and disclosure of contingent assets and liabilities for the periods indicated in the financial statements. Actual results could differ from those estimates. Material estimates that are particularly susceptible to change relate to the determination of the allowance for credit losses, fair value of share-based compensation, the valuation of deferred tax assets and liabilities, contingent liabilities on litigation matters, and the allocation of the purchase price to assets acquired in business combinations.
Reclassifications	*Reclassifications:* Certain prior period amounts have been reclassified to conform to the current presentation. Such reclassifications had no impact on previously reported net income or stockholders’ equity.
Recent accounting pronouncements	*Recent accounting pronouncements:* In April 2015, the Financial Accounting Standards Board (“FASB”) issued an accounting update to simplify the presentation of debt issuance costs. The update 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 a debt discount. The recognition and measurement guidance for debt issuance costs are not affected by the update. The update is effective for annual and interim periods beginning after December 15, 2015. An entity should apply the new guidance on a retrospective basis, wherein the balance sheet of each individual period presented should be adjusted to reflect the period-specific effects of applying the new guidance. In August 2015, the FASB issued an additional accounting update on certain debt issuance costs, which clarifies that debt issuance costs associated with line-of-credit agreements may be classified as an asset or as a direct deduction to the carrying amount of the debt. The debt issuance costs should continue to be deferred and amortized over the term of the line-of-credit. As a result of these accounting updates, debt issuance costs were reclassified from other assets to long-term debt. In February 2016, the FASB issued an accounting update to increase transparency and comparability of accounting for lease transactions. The update requires all leases to be recognized on the balance sheet as lease assets and lease liabilities and requires both quantitative and qualitative disclosures regarding key information about leasing arrangements. All of the Company’s leases are currently classified as operating leases with no lease assets or lease liabilities recorded. The update is effective for annual and interim periods beginning after December 15, 2018, and early adoption is permitted. The Company is currently evaluating the potential impact of this update on its consolidated financial statements. In March 2016, the FASB issued an accounting update to simplify the accounting for share-based compensation, including the accounting for forfeitures, the statutory tax withholding requirements, the accounting for income taxes, and the classification of share-based compensation transactions in the statement of cash flows. The key provision of the update is the requirement for the excess tax benefits or tax deficiencies from the exercise or vesting of share-based awards to flow through the statement of income rather than through additional paid-in-capital on the balance sheet. The standard is effective for interim and annual reporting periods beginning after December 15, 2016, and early adoption is permitted. The Company is currently evaluating the potential impact of this update on its consolidated financial statements. In May 2016, the FASB issued an accounting update providing narrow scope improvements and practical expedients related to the previous update for Revenue from Contracts with Customers. The amendments in this update do not change the core revenue recognition principles. The update addresses certain issues identified in the guidance on assessing collectability, presentation of sales taxes, noncash consideration, and completed contracts and contract modifications at transition. This update is effective for annual and interim periods beginning after December 15, 2017. The Company is currently evaluating the potential impact of the new revenue recognition standard on its consolidated financial statements. In June 2016, the FASB issued an accounting update to change the impairment model for estimating credit losses on financial assets. The current incurred loss impairment model requires the recognition of credit losses when it is probable that a loss has been incurred. The incurred loss model will be replaced by an expected loss model, which requires entities to estimate the lifetime expected credit loss on such instruments and to record an allowance to offset the amortized cost basis of the financial asset. This update is effective for annual and interim periods beginning after December 15, 2019, and early adoption is permitted. The Company is currently evaluating the potential impact of this guidance on its consolidated financial statements.
