Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies The Company’s significant accounting policies are discussed in “Part II – Item 8 – Financial Statements and Supplementary Data – Note 2. Summary of Significant Accounting Policies” in the Annual Report. There have been no significant changes to these significant accounting policies for the nine month period ended September 30, 2017, except as noted below. Transfers of Financial Assets The Company accounts for transfers of financial assets as sales when it has surrendered control over the related assets. Whether control has been relinquished requires, among other things, an evaluation of relevant legal considerations and an assessment of the nature and extent of the Company’s continuing involvement with the assets transferred. Gains and losses resulting from transfers are included in “Other revenue” in the accompanying consolidated statements of operations. Assets obtained and liabilities incurred in connection with transfers reported as sales are initially recognized in the balance sheet at fair value. Transfers of financial assets that do not qualify for sale accounting are reported as secured borrowings. Accordingly, the related assets remain on the Company’s balance sheet and continue to be reported and accounted for as if the transfer had not occurred. Cash proceeds from these transfers are reported as liabilities, with related interest expense recognized over the life of the related transactions. Goodwill and Intangible Assets Goodwill represents the fair value of an acquired business in excess of the aggregate fair value of the identified net assets acquired. Goodwill is not amortized but is tested for impairment annually or whenever events or circumstances indicate that it is more likely than not that the estimated fair value of a reporting unit is below its carrying value. The Company’s annual impairment testing date is April 1. Impairment exists whenever the carrying value of goodwill exceeds its estimated fair value. Adverse changes in impairment indicators such as loss of key personnel, lower than forecast financial performance, increased competition, increased regulatory oversight, or unplanned changes in operations could result in impairment. The Company can elect to qualitatively assess goodwill for impairment if it is more likely than not that the estimated fair value of a reporting unit (generally defined as a component of a business for which financial information is available and reviewed regularly by management) exceeds its carrying value. A qualitative assessment may consider macroeconomic and other industry-specific factors, such as trends in short-term and long-term interest rates and the ability to access capital or company-specific factors, such as market capitalization in excess of net assets, trends in revenue-generating activities and merger or acquisition activity. If the Company does not qualitatively assess goodwill it compares a reporting unit’s estimated fair value to its carrying value. The Company estimates the fair value of a reporting unit using both an income approach and a market approach. The Company relies on the income approach (discounted cash flow method) as the primary method for determining estimated fair value. Market-based methods are used as benchmarks to corroborate the estimated fair value determined by the discounted cash flow method. Both the income approach and the market approach rely on long-term growth rates, and revenue and earnings projections. When applying the income approach, the Company uses a discounted cash flow model, which requires the estimation of cash flows and an appropriate discount rate. The Company projects cash flows expected to be generated by a reporting unit inclusive of an estimated terminal value. The discount rate assumption contemplates a weighted-average cost of capital based on both market observable and company-specific factors. The discount rate is risk-adjusted to include any premiums related to equity price volatility, size, and projected capital structure of publicly traded companies in similar lines of business. The Company relies on several assumptions when estimating the fair value of a reporting unit using the discounted cash flow method. These assumptions include the current discount rate discussed above, as well as transaction fee revenue based on projected loan origination growth, ongoing network provider participation, projected operating expenses and contribution margin, capital expenditures and income taxes. The Company believes these assumptions to be representative of assumptions that a market participant would use in valuing a reporting unit, but these assumptions are inherently uncertain. If the assumptions regarding business operating plans, projected loan origination growth and transaction fee rates, operating expenses, or competition in the industry are not achieved, the Company may be required to record goodwill impairment charges in future periods. There can be no assurances that future estimates and assumptions made for purposes of goodwill impairment testing will prove accurate predictions of the future. The market approach estimates the fair value of a reporting unit based on certain market value multiples of publicly traded companies in similar lines of business, such as total enterprise value to revenue, or to EBITDA. Under the market approach, the Company also considers fair value implied from any relevant and comparable market transactions. Intangible assets are amortized over their useful lives in a manner that best reflects their economic benefit, which may include straight-line or accelerated methods of amortization. Intangible assets are reviewed for impairment quarterly and whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. The Company does not have any indefinite-lived intangible assets. Noncontrolling Interests Noncontrolling interests represent the noncontrolling holders’ share of income or losses, and share of total equity, from a consolidated subsidiary or consolidated VIE in which the Company holds less than 100% ownership. Legal Expenses Legal fees are expensed as incurred and are included in other general and administrative expenses in the consolidated statements of operations. Insurance recoveries associated with the reimbursement of legal expenses incurred, if any, are included in other general and administrative expenses as a contra-expense in the consolidated statements of operations. Adoption of New Accounting Standards The Company adopted the following accounting standards during the nine month period ended September 30, 2017: ASU 2016-09 Compensation – Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting (ASU 2016-09), simplifies the accounting for employee share-based payment transactions, including the associated accounting for income taxes, forfeitures, and classification in the statement of cash flows. The Company adopted ASU 2016-09 effective January 1, 2017, under the modified retrospective method with the cumulative effect of adoption recorded as a reclassification to 2017 beginning accumulated deficit. The Company also elected to present the change in presentation in the Statement of Cash Flows related to excess tax benefits prospectively and, therefore, prior period amounts have not been adjusted. Under ASU 2016-09, the Company now recognizes the excess income tax benefits or deficiencies from stock-based compensation in the income tax provision in the Consolidated Statements of Operations, and as an operating activity in the Consolidated Statements of Cash Flows. Additionally, excess tax benefits and tax deficiencies are now excluded from the calculation of assumed proceeds under the treasury stock method when computing fully diluted earnings per share. Upon the adoption of this standard, the Company recognized a $57.0 million deferred tax asset with a full valuation allowance (net zero impact upon adoption) in the consolidated balance sheets for the excess income tax benefits from stock-based compensation as of January 1, 2017. The Company also elected to recognize forfeitures as they occur for equity awards with only a service condition, rather than estimate expected forfeitures, as permitted by ASU 2016-09. The Company recorded a $1.4 million reclassification to 2017 beginning accumulated deficit to remove the estimate of forfeitures as of January 1, 2017. ASU 2017-04, Intangibles – Goodwill and Other (Topic 350) – Simplifying the Test for Goodwill Impairment, simplifies the accounting for goodwill impairments by eliminating Step 2 of the goodwill impairment test. Under ASU 2017-04, a goodwill impairment loss is now measured as the amount by which the carrying amount of a reporting unit exceeds its fair value. The Company elected to early adopt ASU 2017-04 effective January 1, 2017. The adoption did not have an effect on the Company’s condensed consolidated financial statements for the nine month period ended September 30, 2017. New Accounting Standards Not Yet Adopted Updates to the new accounting standards not yet adopted as disclosed in the Company’s Annual Report for the year ended December 31, 2016 are as follows: In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), which will be effective January 1, 2018. The guidance clarifies that revenue from contracts with customers should be recognized in a manner that depicts both the likelihood of payment and the timing of the related transfer of goods or performance of services. In March 2016, the FASB issued an amendment (ASU 2016-08) to the new revenue recognition guidance clarifying how to determine if an entity is a principal or agent in a transaction. In April (ASU 2016-10) and May (ASU 2016-12) of 2016, the FASB further amended the guidance to include performance obligation identification, licensing implementation, collectability assessment and other presentation and transition clarifications. The effective date and transition requirements for the amendments are the same as for ASU 2014-09. The Company plans to adopt the revenue recognition guidance beginning January 1, 2018 and currently anticipates using the modified retrospective method of adoption. However, the adoption method to be used is subject to completion of the Company’s impact assessment. Upon adoption of Topic 606, as amended, the Company believes there will be no change to (1) the timing and pattern of revenue recognition for its current revenue streams in scope of Topic 606 which includes transaction fees and LCAM investment management fees, (2) the presentation of revenue as gross versus net, or (3) the amount of capitalized contract costs. Because there will be no change to the timing and pattern of revenue recognition, we believe there will be no material changes to the Company’s processes and internal controls. The Company has dedicated internal resources, engaged a service provider, and continues to execute the final phase of its implementation project plan to conclude on the method of adoption and quantify the adoption effects, if any, and prepare the expanded disclosures required by Topic 606. The Company also will continue to evaluate new revenue streams and analyze other aspects of Topic 606 that may become relevant. ASU 2017-09, Compensation – Stock Compensation (Topic 718): Scope of Modification Accounting, (ASU 2017-09), clarifies when to account for a change to the terms or conditions of a share-based payment award as a modification. Under ASU 2017-09, modification accounting is required only if the fair value, the vesting conditions, or the classification of the award (as equity or liability) changes as a result of the change in terms or conditions. The guidance is effective prospectively for all companies for annual periods beginning on or after December 15, 2017. Early adoption is permitted. The Company is still evaluating the impact of this ASU to its consolidated financial statements.

Adoption of New Accounting Standards

The Company adopted the following accounting standards during the nine month period ended September 30, 2017:

ASU 2016-09 Compensation – Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting (ASU 2016-09), simplifies the accounting for employee share-based payment transactions, including the associated accounting for income taxes, forfeitures, and classification in the statement of cash flows.
