Accounting Policies [Abstract]
Basis of Presentation and Significant Accounting Policies	Note 2. Basis of Presentation and Significant Accounting Policies Basis of presentation: 10-Q SEC GAAP 10-Q 10-K Significant accounting policies: Business segments: Principles of consolidation: VIE Treasury stock: Variable interest entities: RMR RMR II The Company’s asset-backed loans under these arrangements are structured to provide enhancements to the lenders in the form of overcollateralization (principal balance of the collateral exceeds the balance of the debt) and reserve funds (restricted cash accounts held by RMR and RMR II). These enhancements, along with the isolated finance receivables, increase the creditworthiness of RMR and RMR II above that of the Company as a whole. This increases the marketability of the Company’s collateral for borrowing purposes, leading to more favorable borrowing terms, improved interest rate risk management, and additional flexibility to grow the business. Both RMR and RMR II are considered VIEs under GAAP and are consolidated into the financial statements of their primary beneficiary. The Company is considered to be the primary beneficiary of RMR and RMR II because it has (i) power over the significant activities of RMR and RMR II through its role as servicer of the finance receivables under each 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 and RMR II after each debt is paid. Consolidation of RMR and RMR II results in the transactions being accounted for as secured borrowings; therefore, the pooled receivables and the related debts remain on the consolidated balance sheet of the Company. Each debt is secured solely by the assets of RMR and RMR II, respectively, and not by any other assets of the Company. The assets of RMR and RMR II are the only source of funds for repayment on each debt. Restricted cash accounts held by RMR and RMR II can only be used to support payments on the debt. The Company recognizes revenue and provision for credit losses on the finance receivables of RMR and RMR II and interest expense on the related secured debt. Use of estimates: Material estimates that are particularly susceptible to change relate to the determination of the allowance for credit losses, the 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: Recent accounting pronouncements: FASB 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 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 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 believes the implementation of the accounting update will have a material effect on the Company’s consolidated financial statements, and is in the process of quantifying the potential impacts. In January 2017, the FASB issued an accounting update to simplify the subsequent measurement of goodwill. The amendment reduces the cost and complexity of evaluating goodwill for impairment by eliminating a step in the goodwill impairment test, which required the same procedure used to determine the fair value of assets acquired and liabilities assumed in a business combination. This update is effective for annual and interim periods beginning after December 15, 2019, and early adoption is permitted. The adoption of this accounting pronouncement will not impact the Company’s consolidated financial statements.

Prior to September 30, 2016, the general component reflected estimated credit losses for groups of finance receivables on a collective basis and was primarily based on historical loss rates (adjusted for qualitative factors). Effective beginning September 30, 2016, the general component is primarily based on delinquency roll rates. Delinquency roll rate modeling is forward-looking and common practice in the consumer finance industry. As a result of this change, the Company decreased the provision for credit losses for the year ended December 31, 2016 by $0.5 million, which increased net income by $0.3 million, or $0.03 diluted earnings per share. Changes in the allowance for credit losses for the periods indicated are as follows: Three Months Ended Nine Months Ended In thousands 2017 2016 2017 2016 Balance at beginning of period $ 42,000 $ 36,200 $ 41,250 $ 37,452 Provision for credit losses 20,152 16,410 57,875 43,587 Credit losses (16,739 ) (14,680 ) (56,736 ) (45,576 ) Recoveries 1,987 1,170 5,011 3,637 Balance at end of period $ 47,400 $ 39,100 $ 47,400 $ 39,100 In September 2017, the Company recorded a $3.0 million increase to the allowance for credit losses related to estimated incremental credit losses on customer accounts impacted by the hurricanes.

The facility has an accordion provision that allows for the expansion of the facility to $700 million. Excluding the receivables held by the Company’s VIEs, the senior revolving credit facility is secured by substantially all of the Company’s finance receivables and equity interests of the majority of its subsidiaries. Borrowings under the facility bear interest, payable monthly, at rates equal to LIBOR of a maturity the Company elects between one and six months, with a LIBOR floor of 1.00%, plus a 3.00% margin, increasing to 3.25% when the availability percentage is below 10%. The LIBOR rate for this facility was 1.25% and 0.88% at September 30, 2017 and December 31, 2016, respectively. Alternatively, the Company may pay interest at the prime rate, plus a 2.00% margin, increasing to 2.25% when the availability percentage is below 10%. The prime rate was 4.25% and 3.75% at September 30, 2017 and December 31, 2016, respectively. The Company pays an unused line fee of 0.50% per annum, payable monthly, decreasing to 0.375% when the average outstanding balance exceeds $413.0 million. Advances on the senior revolving credit facility are capped at 85% of eligible secured finance receivables, plus 70% of eligible unsecured finance receivables. These rates are subject to adjustment at certain credit quality levels (84% of eligible secured finance receivables and 69% of eligible unsecured finance receivables as of September 30, 2017). As of September 30, 2017, the Company had $58.4 million of eligible capacity under the facility. In June 2017, the Company and its wholly-owned subsidiary, RMR II, entered into a credit agreement providing for a $125 million revolving warehouse credit facility to RMR II (expandable to $150 million). RMR II purchases large loan finance receivables, net of the related allowance for credit losses, from the Company’s affiliates using the proceeds of the facility and equity investments from the Company. The facility is secured by the finance receivables owned by RMR II. RMR II held $0.7 million in a restricted cash reserve account as of September 30, 2017 to satisfy provisions of the credit agreement. Through October 1, 2017, borrowings under the facility bore interest, payable monthly, at a blended rate equal to three-month LIBOR, plus a margin of 3.50%. Effective October 2, 2017, the margin decreased to 3.25% following the satisfaction of a milestone associated with the Company’s conversion to a new loan origination and servicing system. The margin may again decrease to 3.00% with the satisfaction of a further system conversion milestone. The three-month LIBOR was 1.34% at September 30, 2017. RMR II pays an unused commitment fee of between 0.35% and 0.85% per annum, payable monthly, based upon the average daily utilization of the facility. Advances on the facility are capped at 80% of finance receivables. In December 2015, the Company and its wholly-owned subsidiary, RMR, entered into a credit agreement providing for a $75.7 million asset-backed, amortizing loan to RMR. RMR purchased $86.1 million in automobile finance receivables, net of a $2.6 million allowance for credit losses, from the Company’s affiliates using the proceeds of the loan and an equity investment from the Company to fund such purchase. The loan is secured by the finance receivables owned by RMR. RMR held $1.7 million in a restricted cash reserve account as of September 30, 2017 to satisfy provisions of the credit agreement. RMR pays interest of 3.00% per annum on the loan balance from the closing date until the date the loan balance has been fully repaid. The amortizing loan terminates in December 2022. The credit agreement allows RMR to prepay the loan when the outstanding balance falls below 20% of the original loan amount. These debt agreements contain restrictive covenants requiring monthly and annual reporting to the banks. At September 30, 2017, the Company was in compliance with all debt covenants. Both the amortizing loan and warehouse credit facility are supported by the expected cash flows from the underlying collateralized finance receivables. Collections on these accounts are remitted to restricted cash collection accounts, which totaled $5.8 million and $2.7 million as of September 30, 2017 and December 31, 2016, respectively. Cash inflows from the finance receivables are distributed to the lenders and service providers in accordance with a monthly contractual priority of payments (waterfall) and, as such, the inflows are directed first to servicing fees. RMR and RMR II pay a 4% servicing fee to the Company, which is eliminated in consolidation. Next, all cash inflows are directed to the interest, principal, and any adjustments to the reserve accounts and, thereafter, to the residual interest that the Company owns. Distributions from RMR and RMR II to the Company are permitted under the credit agreements. Both RMR and RMR II are considered VIEs under GAAP and are consolidated into the financial statements of their primary beneficiary. The Company is considered to be the primary beneficiary of RMR and RMR II because it has (i) power over the significant activities of RMR and RMR II through its role as servicer of the finance receivables under each 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 and RMR II after each debt is paid.

The Company recorded $3.3 million and $3.0 million in share-based compensation for the nine months ended September 30, 2017 and 2016, respectively. As of September 30, 2017, unrecognized share-based compensation expense to be recognized over future periods approximated $6.2 million. This amount will be recognized as expense over a weighted-average period of 1.9 years. Share-based compensation expenses are recognized on a straight-line basis over the requisite service period of the agreement. All share-based compensation is classified as equity awards except for cash-settled performance units, which are classified as liabilities. The Company allows for the settlement of share-based awards on a net share basis. With net share settlement, the employee does not surrender any cash or shares upon the exercise of stock options or the vesting of stock awards or stock units. Rather, the Company withholds the number of shares with a value equivalent to the option exercise price (for stock options) and the statutory tax withholding (for all share-based awards). Net share settlements have the effect of reducing the number of shares that would have otherwise been issued as a result of exercise or vesting. Long-term incentive program: RSUs CSPUs Board In 2016, the Company introduced a key team member incentive program for certain other members of senior management. Recurring annual participation in the program is at the discretion of the Board and executive management. Each participant in the program is eligible to earn a restricted stock award, subject to performance over a one-year one-year two-year Inducement and retention program: Non-employee non-employee The following are the terms and amounts of the awards issued under the Company’s share-based incentive programs: Nonqualified stock options: 18-month 5-year The fair value of option grants are estimated on the grant date using the Black-Scholes option-pricing model with the following weighted-average assumptions for option grants during the periods indicated below.

Commitments and Contingencies	Note 9. Commitments and Contingencies On May 30, 2014, a securities class action lawsuit was filed in the United States District Court for the Southern District of New York (the “District Court”) against the Company and certain of its current and former directors, executive officers, and stockholders (collectively, the “ Defendants 1933 Act Claims Plaintiffs 1934 Act Claims On March 30, 2016, the District Court granted the Defendants’ motion to dismiss the second amended complaint in its entirety. On May 23, 2016, the Plaintiffs moved for leave to file a third amended complaint. The Defendants’ opposition brief was filed on June 9, 2016, and the Plaintiffs’ reply brief was filed on June 20, 2016. On January 27, 2017, the District Court denied the Plaintiffs’ motion for leave to file a third amended complaint and directed entry of final judgment in favor of the Defendants. On January 30, 2017, the District Court entered final judgment in favor of the Defendants. On March 1, 2017, the Plaintiffs filed a notice of appeal to the United States Court of Appeals for the Second Circuit (the “ Appellate Court The Company believes that the claims against it are without merit and will continue to defend against the litigation vigorously. Because the lawsuit contains multiple 1933 Act Claims and 1934 Act Claims, each with varying probabilities of being overturned on appeal and varying probabilities of loss and loss amounts, the Company is unable to estimate the reasonably possible loss or range of reasonably possible loss arising from this matter. The Company’s primary insurance carrier during the applicable time period has (i) denied coverage for the 1933 Act Claims and (ii) acknowledged coverage of the Company and other insureds for the 1934 Act Claims under a reservation of rights and subject to the terms and conditions of the applicable insurance policy. The parties are in the process of negotiating an allocation between denied and acknowledged claims. In the normal course of business, the Company has been named as a defendant in legal actions, including arbitrations, class actions, and other litigation arising in connection with its activities. Some of the actual or threatened legal actions include claims for compensatory and punitive damages or claims for indeterminate amounts of damages. While the Company will continue to identify legal actions where the Company believes a material loss to be reasonably possible and reasonably estimable, there can be no assurance that material losses will not be incurred from claims that the Company has not yet been notified of or are not yet determined to be probable, or reasonably possible and reasonable to estimate. The Company contests liability and the amount of damages, as appropriate, in each pending matter. Where available information indicates that it is probable that a liability has been incurred and the Company can reasonably estimate the amount of that loss, the Company accrues the estimated loss by a charge to net income. In many actions, however, it is inherently difficult to determine whether any loss is probable or even reasonably possible or to estimate the amount of loss. In addition, even where a loss is reasonably possible or an exposure to loss exists in excess of the liability already accrued, it is not always possible to reasonably estimate the size of the possible loss or range of loss. For certain legal actions, the Company cannot reasonably estimate such losses, particularly for actions that are in their early stages of development or where plaintiffs seek indeterminate damages. Numerous issues may need to be resolved, including through lengthy discovery and determination of important factual matters, and by addressing novel or unsettled legal questions relevant to the actions in question, before a loss, additional loss, range of loss, or range of additional loss can be reasonably estimated for any given action. For certain other legal actions, the Company can estimate reasonably possible losses, additional losses, ranges of loss, or ranges of additional loss in excess of amounts accrued, but the Company does not believe, based on current knowledge and after consultation with counsel, that such losses will have a material adverse effect on the consolidated financial statements. The Company expenses legal costs as they are incurred.

Principles of consolidation	Principles of consolidation: VIE
Treasury stock	Treasury stock:
Variable interest entities	Variable interest entities: RMR RMR II The Company’s asset-backed loans under these arrangements are structured to provide enhancements to the lenders in the form of overcollateralization (principal balance of the collateral exceeds the balance of the debt) and reserve funds (restricted cash accounts held by RMR and RMR II). These enhancements, along with the isolated finance receivables, increase the creditworthiness of RMR and RMR II above that of the Company as a whole. This increases the marketability of the Company’s collateral for borrowing purposes, leading to more favorable borrowing terms, improved interest rate risk management, and additional flexibility to grow the business. Both RMR and RMR II are considered VIEs under GAAP and are consolidated into the financial statements of their primary beneficiary. The Company is considered to be the primary beneficiary of RMR and RMR II because it has (i) power over the significant activities of RMR and RMR II through its role as servicer of the finance receivables under each 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 and RMR II after each debt is paid. Consolidation of RMR and RMR II results in the transactions being accounted for as secured borrowings; therefore, the pooled receivables and the related debts remain on the consolidated balance sheet of the Company. Each debt is secured solely by the assets of RMR and RMR II, respectively, and not by any other assets of the Company. The assets of RMR and RMR II are the only source of funds for repayment on each debt. Restricted cash accounts held by RMR and RMR II can only be used to support payments on the debt. The Company recognizes revenue and provision for credit losses on the finance receivables of RMR and RMR II and interest expense on the related secured debt.
Use of estimates	Use of estimates: Material estimates that are particularly susceptible to change relate to the determination of the allowance for credit losses, the 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.

Recent accounting pronouncements	Recent accounting pronouncements: FASB 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 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 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 believes the implementation of the accounting update will have a material effect on the Company’s consolidated financial statements, and is in the process of quantifying the potential impacts. In January 2017, the FASB issued an accounting update to simplify the subsequent measurement of goodwill. The amendment reduces the cost and complexity of evaluating goodwill for impairment by eliminating a step in the goodwill impairment test, which required the same procedure used to determine the fair value of assets acquired and liabilities assumed in a business combination. This update is effective for annual and interim periods beginning after December 15, 2019, and early adoption is permitted. The adoption of this accounting pronouncement will not impact the Company’s consolidated financial statements.

Effective beginning September 30, 2016, the general component is primarily based on delinquency roll rates. Delinquency roll rate modeling is forward-looking and common practice in the consumer finance industry.
