Recently Issued Accounting Standards [Abstract]
Description of New Accounting Pronouncements Not yet Adopted [Text Block]	RECENTLY ISSUED ACCOUNTING STANDARDS (a) Adoption of New Accounting Standards: Effective January 1, 2018, the Company adopted Accounting Standards Update ("ASU") 2014-09, Revenue from Contracts with Customers ("ASU 2014-09"), and the related amendments, utilizing the modified retrospective approach, which created a new comprehensive revenue recognition standard that serves as the single source of revenue guidance for all contracts with customers to transfer goods or services or contracts for the transfer of nonfinancial assets, unless those contracts are within the scope of other standards. The core principle of ASU 2014-09 is that an entity recognizes 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. Insurance contracts, lease contracts and investments are not within the scope of ASU 2014-09. ASU 2014-09 is applicable to the Company's service fee and commission income. Service fee and commission income represents vehicle service agreement fees, GAP commissions, maintenance support service fees, warranty product commissions, homebuilder warranty service fees and homebuilder warranty commissions based on terms of various agreements with credit unions, consumers, businesses and homebuilders. With the exception of GAP commissions and homebuilder warranty service fees, the adoption of ASU 2014-09 did not change the way the Company recognized revenue for the year ended December 31, 2018. The new guidance affects IWS' GAP commissions and PWSC's homebuilder warranty service fees, which will be recognized more slowly as compared to the historic revenue recognition pattern prior to the Company’s adoption of ASU 2014-09. As a result of the adoption of ASU 2014-09, the Company also recorded a cumulative effect adjustment to increase accumulated deficit by $0.6 million and increase deferred service fees by $0.6 million. Prior periods have not been restated to conform to the current presentation. Refer to Note 20, "Revenue from Contracts with Customers," for further details. Effective January 1, 2018, the Company adopted ASU 2016-01, Financial Instruments-Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities ("ASU 2016-01"). The amendments in ASU 2016-01 address certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. Most significantly, ASU 2016-01 requires (1) equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of an investee) to be measured at fair value with changes in fair value recognized in net income (loss); however, an entity may choose to measure equity investments that do not have readily determinable fair values at cost, adjusted for observable price changes and impairments; and (2) an entity to present separately in other comprehensive income (loss) the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments. The Company has elected to measure its investments in private companies at cost, adjusted for observable price changes and impairments. Previously, the Company recorded its equity investments at fair value with net unrealized gains or losses reported in accumulated other comprehensive income (loss) and its subordinated debt at fair value with the total change in fair value reported in net income (loss). As a result of the adoption of ASU 2016-01, at January 1, 2018 cumulative net unrealized losses on equity investments of $0.0 million were reclassified from accumulated other comprehensive income (loss) into accumulated deficit and a cumulative $40.5 million change in fair value of subordinated debt attributable to instrument-specific credit risk was reclassified from accumulated deficit to accumulated other comprehensive income (loss). Prior periods have not been restated to conform to the current presentation. Effective January 1, 2018, the Company adopted ASU 2016-15, Classification of Certain Cash Receipts and Cash Payments ("ASU 2016-15"). The objective of ASU 2016-15 is to reduce diversity in the classification of cash receipts and payments for specific cash flow issues, including debt prepayment or debt extinguishment costs, contingent consideration payments made after a business combination and proceeds from the settlement of insurance claims. The adoption of the standard did not affect the Company's consolidated statements of cash flows. Effective January 1, 2018, the Company adopted ASU 2016-18, Statement of Cash Flows (Topic 230) Restricted Cash ("ASU 2016-18"). The objective of ASU 2016-18 is to explain the change during the period in the total cash, cash equivalents and amounts generally described as restricted cash or restricted cash equivalents. Amounts generally described as restricted cash and cash equivalents should be included with the cash and cash equivalents when reconciling the beginning of period and end of period total amounts shown on the statement of cash flows. As a result of the adoption of the standard, the change in restricted cash is included in the consolidated statements of cash flows. Effective July 1, 2018, the Company adopted ASU 2018-07, Compensation-Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting ("ASU 2018-07"). ASU 2018-07 was issued to simplify the accounting for share-based transactions by expanding the scope of Topic 718 from only being applicable to share-based payments to employees to also include share-based payment transactions for acquiring goods and services from nonemployees. During the third quarter of 2018, the Company granted restricted common stock awards to a nonemployee. Refer to Note 23, "Stock-Based Compensation," for further details. (b) Accounting Standards Not Yet Adopted: In February 2016, the FASB issued ASU 2016-02, Leases ("ASU 2016-02"). ASU 2016-02 was issued to improve the financial reporting of leasing transactions. Under current guidance for lessees, leases are only included on the balance sheet if certain criteria, classifying the agreement as a capital lease, are met. This update will require the recognition of a right-of-use asset and a corresponding lease liability, discounted to the present value, for all leases that extend beyond 12 months. For operating leases, the asset and liability will be amortized over the lease term on a straight-line basis, with all cash flows included within operating activities in the statement of cash flows. The accounting treatment for lessors will remain relatively unchanged. ASU 2016-02 is effective for annual and interim reporting periods beginning after December 15, 2018. The Company will adopt ASU 2016-02 effective January 1, 2019 using the modified retrospective transition method and will not restate comparative periods. The Company plans to elect the package of practical expedients permitted under the transition guidance within ASU 2016-02, which will allow the Company to carry forward prior conclusions about lease identification, classification and initial direct costs for leases entered into prior to adoption of ASU 2016-02. The adoption of ASU 2016-02 will have no impact on the Company's shareholders' equity as of January 1, 2019, but the Company estimates it will record a right-of-use asset of approximately $2.7 million; a corresponding lease liability of approximately $2.9 million; and a reversal of December 31, 2018 accrued rent expense of $0.2 million. In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments ("ASU 2016-13"). ASU 2016-13 replaces the current incurred loss model used to measure impairment losses with an expected loss model for trade, reinsurance, and other receivables as well as financial instruments measured at amortized cost. ASU 2016-13 will require a financial asset measured at amortized cost, including reinsurance balances recoverable, to be presented at the net amount expected to be collected by means of an allowance for credit losses that runs through net loss. Credit losses relating to available-for-sale debt securities will also be recorded through an allowance for credit losses. However, the amendments would limit the amount of the allowance to the amount by which fair value is below amortized cost. The measurement of credit losses on available-for-sale investments is similar under current GAAP, but the update requires the use of the allowance account through which amounts can be reversed, rather than through irreversible write-downs. ASU 2016-13 is effective for annual periods beginning after December 15, 2019, and interim periods within those annual periods with early adoption permitted for fiscal years beginning after December 31, 2018 and interim periods within such year. The Company is currently evaluating ASU 2016-13 to determine the potential impact that adopting this standard will have on its consolidated financial statements. In January 2017, the FASB issued ASU 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment ("ASU 2017-04"). ASU 2017-04 was issued to simplify the subsequent measurement of goodwill. This update changes the impairment test by requiring an entity to compare the fair value of a reporting unit with its carrying amount as opposed to comparing the carrying amount of goodwill with its implied fair value. ASU 2017-04 is effective for annual and interim reporting periods beginning after December 15, 2019. Early adoption is permitted. The Company does not believe the adoption of ASU 2017-04 will have a material effect on its consolidated financial statements.
