Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation LendingClub Corporation (LendingClub) operates an online lending marketplace platform that connects borrowers and investors. Various wholly-owned subsidiaries of LendingClub have been established to enter into borrowing agreements with certain lenders for secured credit facilities. Additionally, LendingClub has established various entities to facilitate loan sale transactions, including sponsoring asset-backed securitization transactions and Certificate Program transactions (collectively referred to as Structured Program transactions), where certain accredited investors and qualified institutional buyers have the opportunity to invest in senior and subordinated securities backed by a pool of unsecured personal whole loans. Certificate Program transactions include CLUB Certificate and Levered Certificate transactions. LC Trust I (the LC Trust) is an independent Delaware business trust that acquires loans from LendingClub and holds them for the sole benefit of certain investors that have purchased trust certificates issued by the LC Trust that are related to specific underlying loans for the benefit of the investor. Springstone Financial, LLC (Springstone), is a wholly-owned subsidiary of LendingClub that facilitates education and patient finance loans originated by third-party issuing banks. The accompanying consolidated financial statements include LendingClub, its subsidiaries (collectively referred to as the Company, we, or us) and consolidated variable interest entities (VIEs). Noncontrolling interests are reported as a separate component of consolidated equity from the equity attributable to LendingClub’s stockholders for all periods presented. All intercompany balances and transactions have been eliminated. These consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (GAAP) for financial information and, in the opinion of management, contain all adjustments, consisting of only normal recurring adjustments, necessary for the fair statement of the results and financial position for the periods presented. These accounting principles require management to make certain estimates and assumptions that affect the amounts in the accompanying financial statements. These estimates and assumptions are inherently subjective in nature and actual results may differ from these estimates and assumptions, and the differences could be material. Certain prior-period amounts have been reclassified to conform to the current period presentation. A 1-for-5 reverse stock split of the Company’s common stock became effective on July 5, 2019. As a result, prior period share and per share amounts presented in the accompanying consolidated financial statements and these related notes were retroactively adjusted accordingly. See “ Note 4. Net Loss Per Share ” for additional information. In the fourth quarter of 2019, the Company presented operating lease assets and operating lease liabilities separately from “Other assets” and “Accrued expenses and other liabilities,” respectively, on its Consolidated Balance Sheets. In the first quarter of 2019, the Company presented a new sub-total caption called “Net investor revenue” on its Condensed Consolidated Statements of Operations and also reordered the presentation of certain of its existing captions. The Company believes this new presentation allows shareholders a view of net investor revenue and our capital markets activity, which includes net interest income and fair value adjustments of loans and securities available for sale, gain on sales of loans invested in by the Company and investor fees from servicing of loans. These changes in presentation had no impact on prior period amounts presented. The Company presents loans under a number of different captions to align the assets to their associated liabilities, if any. “Loans held for investment at fair value” are loans which are related to the Company’s retail notes, certificates and secured borrowings program. The Company is not exposed to market risk, interest rate risk or credit risk on these loans and all loan cash flows flow directly to the retail note, certificate and secured borrowing owners. The associated liability for this loan category is included in the caption “Notes, certificates and secured borrowings at fair value.” Loans included in “Loans held for investment by the Company at fair value” and “Loans held for sale by the Company at fair value” are loans which the Company has purchased and from which the Company earns interest income and records net fair value adjustments in earnings for changes in the valuation of loans.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Cash and Cash Equivalents Cash and cash equivalents include the Company’s unrestricted deposits with investment-grade financial institutions, institutional money market funds, certificates of deposit, and commercial paper. The Company considers all highly liquid investments with stated maturity dates of three months or less from the date of purchase to be cash equivalents. Restricted Cash Restricted cash consists primarily of bank deposits and money market funds that are: (i) pledged as security for transactions processed on or related to LendingClub’s platform or activities by certain investors; and (ii) received from the borrower and applied to the loan, but not yet distributed to the investor’s internal platform account or sent to their external account. Investor cash balances (excluding transactions-in-process) are held in segregated bank or custodial accounts and are not commingled with the Company’s monies or held on the Company’s Consolidated Balance Sheets . Securities Available for Sale Debt securities that the Company might not hold until maturity are classified as securities available for sale. In structured program transactions that meet the applicable criteria to be accounted for as a sale, the Company retains certain asset-backed securities including subordinated residual interests and CLUB Certificates, which are classified as securities available for sale. Securities available for sale are recorded at fair value and unrealized gains and losses are reported, net of taxes, in “Accumulated other comprehensive income (loss)” included in Equity in the Company’s Consolidated Balance Sheets unless management determines that a security is other-than-temporarily impaired (OTTI). Realized gains and losses from sales of securities available for sale are included in “Net fair value adjustments” in the Company’s Consolidated Statements of Operations . Management evaluates whether debt securities available for sale with unrealized losses are OTTI on a quarterly basis. If the Company intends to sell the security, or if it is more likely than not that it will be required to sell the security before recovery, an OTTI is recognized in earnings equal to the entire difference between the amortized cost basis and fair value of the debt security. However, even if the Company does not expect to sell a debt security it must evaluate the expected cash flows to be received and determine if a credit loss exists. In the event of a credit loss, only the amount of impairment associated with the credit loss is recognized in earnings and amounts related to factors other than credit losses are recorded in other comprehensive income. Impairment charges are recorded in “Net fair value adjustments” in the Company’s Consolidated Statements of Operations . Loans Held for Investment by the Company and Loans Held for Sale by the Company The Company has elected the fair value option for loans held for investment by the Company and loans held for sale by the Company. Changes in the fair value of loans held by the Company are recorded in “Net fair value adjustments” in the Consolidated Statements of Operations in the period of the fair value changes. The Company places loans held by the Company on non-accrual status at 90 days past due. Accrued interest income on loans held by the Company is calculated based on the contractual interest rate of the loan held by the Company and recorded as interest income as earned. When a loan held by the Company is placed on non-accrual status, the Company stops accruing interest and reverses all accrued but unpaid interest as of such date. The Company charges-off loans held by the Company no later than 120 days past due. Loans Held for Investment and Related Notes and Certificates The Company has elected the fair value option for loans held for investment and related notes and certificates. Due to the payment dependent feature of the notes and certificates, changes in the fair value of the notes and certificates are offset by changes in the fair values of related loans, resulting in no net effect on the Company’s earnings. The Company places loans held for investment on non-accrual status at 90 days past due. Interest receivable on loans held for investment and accrued interest payable on notes and certificates are reduced when the corresponding loan held for investment is placed on non-accrual status due to the payment dependent nature of the loans held for investment and related notes and certificates. The Company charges-off loans held for investment and related notes and certificates no later than 120 days past due. Servicing Assets The Company records servicing assets at their estimated fair values when it sells loans or when the Company assumes or acquires a servicing obligation whereby the underlying loans are not included in its financial statements. The gain or loss on a loan sale is recorded separately in “Gain on sales of loans” in the Company’s Consolidated Statements of Operations while the component of the gain or loss that is based on the degree to which the contractual servicing fee is above or below an estimated market servicing rate is recorded as a servicing asset. Servicing assets are reported in “Other assets” on the Company’s Consolidated Balance Sheets . Changes in the fair value of servicing assets are reported in “Investor fees” in the Company’s Consolidated Statements of Operations in the period in which the changes occur. Fair Value of Assets and Liabilities Fair value is the price that would be received to sell a financial asset or paid to transfer a financial liability in an orderly transaction between market participants at the measurement date (an exit price). The Company uses fair value measurements in its fair value disclosures and to record securities available for sale, loans held for investment and loans held for sale, notes and certificates, and servicing assets and liabilities at fair value on a recurring basis. The fair value hierarchy includes a three-level classification, which is based on whether the inputs to the valuation methodology used for measurement are observable: Level 1 — Quoted market prices in active markets for identical assets or liabilities. Level 2 — Inputs other than quoted prices included in Level 1 that are observable for the asset or liability either directly or indirectly. Level 3 — Unobservable inputs. When developing fair value measurements, the Company maximizes the use of observable inputs and minimizes the use of unobservable inputs. However, for certain instruments the Company must utilize unobservable inputs in determining fair value due to the lack of observable inputs in the market, which requires greater judgment in measuring fair value. In instances where there is limited or no observable market data, fair value measurements for assets and liabilities are based primarily upon the Company’s own estimates, and the measurements reflect information and assumptions that management believes a market participant would use in pricing the asset or liability. Loans held for investment, loans held for sale and related notes, certificates and secured borrowings, are measured at estimated fair value using a discounted cash flow model. The fair valuation methodology considers projected prepayments, underwriting changes and the historical actual defaults, losses and recoveries on the Company’s loans to project future losses and net cash flows on loans. Net cash flows on loans are discounted using an estimate of market rates of return. Loan servicing assets are measured at estimated fair value using a discounted cash flow model. The cash flows in the valuation model represent the difference between the contractual servicing fees charged to investors and an estimated market servicing rate. Since contractual servicing fees are generally based on the monthly unpaid principal balance of the underlying loans, the expected cash flows in the model incorporate estimates of net expected losses and prepayments. The Company uses prices obtained from third-party pricing services to measure the fair value of securities available for sale when available. The Company compares the prices obtained from its primary independent pricing service to the prices obtained from the additional independent pricing services to determine if the price obtained from the primary independent pricing service is reasonable. When third-party pricing services are not available for a security, such as subordinated residual certificates and CLUB Certificates, the Company measures the fair value of these securities using a discounted cash flow model incorporating inputs consistent with loans held for investment, loans held for sale and related notes, certificates, secured borrowings, and payable to securitization note and certificate holders. Property, Equipment and Software, net Property, equipment and software are carried at cost less accumulated depreciation and amortization. The Company uses the straight-line method of depreciation and amortization. Estimated useful lives range from three years to five years for furniture and fixtures, computer equipment, and software. Leasehold improvements are amortized over the shorter of the lease term or the estimated useful life. Internally developed software is capitalized when preliminary development efforts are successfully completed and it is probable that the project will be completed, and the software will be used as intended. Capitalized costs consist of salaries and compensation costs for employees, fees paid to third-party consultants who are directly involved in development efforts, and costs incurred for upgrades and enhancements to add functionality of the software. Other costs are expensed as incurred. The Company evaluates impairments of its property, equipment and software whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. If the asset is not recoverable, measurement of an impairment loss is based on the fair value of the asset. When an impairment loss is recognized, the carrying amount of the asset is reduced to its estimated fair value. 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 more frequently 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 an operating segment or one level below an operating segment 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 either an income approach (discounted cash flow model) or the income approach corroborated by a market approach. Goodwill impairment loss is measured as the amount by which the carrying amount of a reporting unit exceeds its fair value. 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 and revenue growth, projected operating expenses and Contribution Margin, direct and allocated general and administrative and technology expenses, 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 involve the use of estimates and judgments, particularly related to future cash flows, which are inherently uncertain. There can be no assurances that 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. Goodwill impairment loss is measured as the amount by which the carrying amount of a reporting unit exceeds its fair value. See “ Note 11. Intangible Assets and Goodwill ” for additional information. 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 indefinite-lived intangible assets. Loss Contingencies Loss contingencies, including claims and legal actions arising in the ordinary course of business, are recorded as liabilities in “Accrued expenses and other liabilities” in the Company’s Consolidated Balance Sheets . Associated legal expense is recorded in “Other general and administrative” expense or in “Class action and regulatory litigation expense” for the losses associated with the securities class action lawsuits, as described in “ Note 19. Commitments and Contingencies , ” in the Company’s Consolidated Statements of Operations . Such liabilities and associated expenses are recorded when the likelihood of loss is probable and an amount or range of loss can be reasonably estimated. The Company will also disclose a range of exposure to incremental loss when such amounts are reasonably possible and can be estimated. In estimating the Company’s exposure to loss contingencies, if an amount within the estimated range of loss is the best estimate, that amount will be accrued. However, if there is no amount within the estimated range of loss that is the best estimate, the Company will accrue the minimum amount within the range, and disclose the amount up to the high end of the range as an exposure to incremental loss, if such amount is considered reasonably possible. Such estimates are based on the best information available at the time. As additional information becomes available, the Company reassesses the potential liability and records an adjustment to its estimate in the period in which the adjustment is probable and an amount or range can be reasonably estimated. The determination of an expected contingent liability and associated litigation expense requires the Company to make assumptions related to the outcome of these matters. Due to the inherent uncertainties of loss contingencies, the Company’s estimates may be different than the actual outcomes. Legal fees, including legal fees associated with loss contingencies, are recognized as incurred and included in “Other general and administrative” expense in the Company’s Consolidated Statements of Operations . Insurance Recoveries Insurance recoveries of all or a portion of incurred losses are recognized when realization of the claim for recovery is probable. Any insurance recoveries in excess of losses incurred are accounted for as a gain contingency. Insurance recoveries are recorded in “Other assets” in the Company’s Consolidated Balance Sheets . Insurance recoveries associated with the reimbursement of legal expenses arising from loss contingencies and legal fees are recorded as a contra-expense in “Other general and administrative” expense or, if such recoveries are associated with the securities class action lawsuits, as a contra-expense in “Class action and regulatory litigation expense” in the Company’s Consolidated Statements of Operations . Revenue Recognition Transaction Fees : The Company has a single performance obligation to provide customers access to the Company’s platform. Transaction fees are considered revenue from contracts with customers, including issuing banks and education and patient service providers. The Company recognizes transaction fee revenue each time a loan is facilitated by the Company, who provides loan application processing and loan facilitation services, resulting in a loan issued by the customers. Transaction fees are based on the initial principal amount of the loans facilitated by the Company and paid by the issuing banks and education and patient service providers each time a loan is issued by the issuing banks. Transaction fees to which the Company expects to be entitled are variable consideration because loan volume originated over the contractual term is not known at the contract’s inception. The transaction fee is determined each time a loan is issued based on that loan’s initial principal amount. The Company pays WebBank a loan trailing fee to give WebBank an ongoing financial interest in the performance of the loans it originates and sells to the Company. The Loan Trailing Fee is paid over time based on the amount and timing of principal and interest payments made by borrowers of the underlying loans. The Loan Trailing Fee is consideration payable to WebBank and the loan trailing fee liability is recorded at fair value. Additionally, the Company assumes the issuing bank’s obligation under Utah law to refund the pro-rated amount of the transaction fee in excess of 5% in the event the borrower prepays the loan in full before maturity. Both the loan trailing fees and transaction fee refunds are recorded as a reduction of transaction fee revenue in the Company’s Consolidated Statements of Operations and are included in “Accrued expenses and other liabilities” on the Company’s Consolidated Balance Sheets. Other Revenue : Other revenue primarily consists of referral fee revenue and sublease revenue from our sublet office space in San Francisco, California. The Company is entitled to receive referral fees from third-party companies when customers referred by the Company consider or purchase products or services from such third-party companies. Referral contracts contain a single performance obligation. The Company recognizes referral fees for each distinct instance when the criteria for receiving the referral fee has been satisfied. Sublease revenue is recognized on a straight-line basis over the term of the lease. Stock-based Compensation Stock-based compensation includes expense associated with restricted stock units (RSUs) and performance-based restricted stock units (PBRSUs), stock options, and the Company’s employee stock purchase plan (ESPP), as well as expense associated with stock issued related to acquisitions. Stock-based compensation expense is based on the grant date fair value of the award. The cost is generally recognized over the vesting period on a straight-line basis. Forfeitures are recognized as incurred. Income Taxes The Company accounts for income taxes under the asset and liability method. Under this method, deferred tax assets and liabilities are determined on the basis of the differences between the financial statement and tax bases of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date. The Company recognizes deferred tax assets to the extent that it believes these assets are more likely than not to be realized. In making such a determination, the Company considers the available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies, and results of recent operations. Valuation allowances are established when necessary to reduce deferred tax assets to the amounts that are more likely than not expected to be realized. If the Company determines that it is able to realize its deferred tax assets in the future in excess of the net recorded amount, the Company decreases the deferred tax asset valuation allowance, which reduces the provision for income taxes. Uncertain tax positions are recognized only when we believe it is more likely than not that the tax position will be upheld on examination by the taxing authorities based on the merits of the position. The Company recognizes interest and penalties, if any, related to uncertain tax positions in “Income tax expense (benefit)” in the Consolidated Statements of Operations. Net Income (Loss) Per Share Basic net income (loss) per share (Basic EPS) attributable to common stockholders is computed by dividing net income (loss) attributable to LendingClub by the weighted-average number of shares of common stock outstanding during the period. Diluted net income (loss) per share (Diluted EPS) is computed by dividing net income (loss) attributable to LendingClub by the weighted-average number of shares of common stock outstanding during the period, adjusted for the effects of dilutive shares of common stock, which include incremental shares issued for RSUs, PBRSUs, and stock options. PBRSUs are included in dilutive shares to the extent the pre-established targets have been or are estimated to be satisfied as of the reporting date. The dilutive potential common shares are computed using the treasury stock method. The effects of outstanding RSUs, PBRSUs, and stock options are excluded from the computation of Diluted EPS in periods in which the effect would be antidilutive. Consolidation of Variable Interest Entities A variable interest entity (VIE) is a legal entity that has either a total equity investment that is insufficient to finance its activities without additional subordinated financial support or whose equity investors lack the characteristics of a controlling financial interest. The Company’s variable interest arises from contractual, ownership or other monetary interests in the entity, which change with fluctuations in the fair value of the entity’s net assets. A VIE is consolidated by its primary beneficiary, the party that has both the power to direct the activities that most significantly impact the VIE’s economic performance, and the obligation to absorb losses or the right to receive benefits of the VIE that could potentially be significant to the VIE. The Company consolidates a VIE when it is deemed to be the primary beneficiary. The Company assesses whether or not it is the primary beneficiary of a VIE on an ongoing basis. Transfers of Financial Assets The Company accounts for transfers of financial assets as sales when it has surrendered control over the transferred assets. Control is generally considered to have been surrendered when the transferred assets have been legally isolated from the Company, the transferee has the right to pledge or exchange the assets without any significant constraints, and the Company has not entered into a repurchase agreement, does not hold unconditional call options and has not written put options on the transferred assets. In assessing whether control has been surrendered, the Company considers whether the transferee would be a consolidated affiliate and the impact of all arrangements or agreements made contemporaneously with, or in contemplation of the transfer, even if they were not entered into at the time of transfer. The Company measures gain or loss on sale of financial assets as the net proceeds received on the sale less the carrying amount of the loans sold. The net proceeds of the sale represent the fair value of any assets obtained or liabilities incurred as part of the transaction, including, but not limited to servicing assets, retained securities, and recourse obligations. 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 Consolidated Balance Sheets 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 assets. Adoption of New Accounting Standards The Company adopted the following accounting standards during the year ended December 31, 2019 : Accounting Standards Update (ASU) 2016-02, Leases (Topic 842), requires lessees to record on their balance sheets a lease liability for the obligation to make lease payments and a right-of-use (ROU) asset for the right to use the underlying asset for the lease term. The Company adopted Topic 842 as of January 1, 2019 and has elected not to restate comparative periods presented in the consolidated financial statements. The Company has chosen not to elect the practical expedients permitted under the transition guidance within the new standard, which among other things, permits entities to carry forward their historical lease identification. The Company has made an accounting policy election to not recognize lease liabilities and ROU assets for short-term leases, which are leases with initial terms of 12 months or less and for which there is not a purchase option that is reasonably certain to be exercised. All leases within the Company’s portfolio are classified as operating leases. Adoption of Topic 842 had an impact on the Company’s Consolidated Balance Sheets but did not have an impact on the Company’s Consolidated Statements of Operations or Consolidated Statements of Cash Flows . The most significant impact was the recognition of ROU assets and lease liabilities of $95.2 million and $110.1 million at the time of adoption, respectively, with no cumulative effect in retained earnings. The difference between the ROU assets and lease liabilities is the unamortized balance of deferred rent, which prior to January 1, 2019, was included as a separate liability within Accrued expenses and other liabilities. The operating lease expenses are included in Other general and administrative expense and sublease income is recorded in Other revenue in the Company’s Consolidated Statements of Operations . The Company included the disclosures required by ASU 2016-02 in “ Note 18. Leases .” In July 2019, the Financial Accounting Standards Board (FASB) issued ASU 2019-07, Codification Updates to SEC Sections . The ASU clarifies and/or improves the disclosure and presentation requirements of a variety of codification topics by aligning them with the Securities and Exchange Commission’s regulations, thereby eliminating redundancies and making the codification easier to apply. This ASU became effective upon issuance and did not have a significant impact on the Company’s consolidated financial statements and related disclosures. New Accounting Standards Not Yet Adopted In June 2016, the FASB amended guidance related to impairment of financial instruments as part of ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments , which became effective on January 1, 2020. For loans accounted for at amortized cost, the guidance replaces the incurred loss impairment methodology with an expected credit loss model for which a company recognizes an allowance based on the estimate of expected credit loss. Because the Company has elected the fair value option for loans and loans accounted for at fair value through net income are outside the scope of Topic 326, the Company expects no impact on its loan portfolios upon adoption. For accrued interest receivable related to such loans, the Company has made an accounting policy election not to measure an allowance for credit losses on accrued interest receivable as the Company writes off uncollectible accrued interest receivable in a timely manner. Uncollectible accrued interest receivable amounts are written off to interest income. For debt securities available for sale, Topic 326 requires recognition of expected credit losses by recognizing an allowance for credit losses when the fair value of the security is below amortized cost and the recognition of this allowance is limited to the difference between the security’s amortized cost basis and fair value. The standard eliminates the existing guidance for purchased credit impaired assets but requires an allowance for purchased financial assets with more than insignificant deterioration since origination. The measurement guidance for purchased financial assets with credit deterioration also applies to beneficial interests classified as available for sale where there is a significant difference between contractual and expected cash flows at the date of recognition. Upon adoption, the amendments in Topic 326 will be recognized through a cumulative-effect adjustment to retained earnings, except for debt securities with prior other-than-temporary impairment whereby Topic 326 is applied prospectively. The Company made substantial progress in line with the established project plan and determined there was not a transition adjustment upon adoption of the standard on January 1, 2020. The targeted amendments to the debt securities available for sale impairment model do not have a material impact on the Company’s financial position, results of operations, cash flows, and disclosures for transition securities; the Company is still evaluating the impact for new securities acquired on and after January 1, 2020. In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement , which modifies the disclosure requirements on fair value measurements by removing, modifying, or adding certain disclosures. The ASU eliminates such disclosures as the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy and valuation processes for Level 3 fair value measurements. The ASU adds new disclosure requirements for Level 3 measurements. The new guidance became effective on January 1, 2020. The Company is finalizing the impact this ASU will have on its disclosures and does not expect such adoption to have a material impact. In August 2018, the FASB issued ASU 2018-15, Intangibles – Goodwill and Other – Internal-Use Software – (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract , which requires a customer in a hosting arrangement that is a service contract to follow the internal-use software guidance in ASC 350-40 to determine which implementation costs to capitalize as assets or expense as incurred. The standard became effective on January 1, 2020 and the Company adopted the standard using the prospective approach. The Company has reviewed existing cloud computing arrangements and determined which ones are service contracts. Implementation costs that are not from internal developers related to service contracts that satisfy the criteria for capitalization under ASC 350-40 will be presented with “Other assets” on the Company’s Consolidated Balance Sheet

Revenue from Contracts with Customers	Revenue from Contracts with Customers The Company’s revenue from contracts with customers includes transaction fees and referral fees. Referral fees are presented as a component of “Other revenue” in the Consolidated Statements of Operations . The following table presents the Company’s revenue from contracts with customers, disaggregated by revenue source for services transferred over time, for the years ended December 31, 2019 and 2018 : Year Ended December 31, 2019 2018 Transaction fees $ 598,760 $ 526,942 Referral fees 5,474 3,645 Total revenue from contracts with customers $ 604,234 $ 530,587 The Company recognizes transaction and referral fees at each distinct instance after the Company satisfies its performance obligations. The Company had no bad debt expense for the years ended December 31, 2019 and 2018 . Because revenue is recognized at the same time that payments are received, the Company had no contract assets, contract liabilities, or deferred contract costs recorded as of December 31, 2019 and 2018 . Additionally, the Company did not recognize any revenue from performance obligations related to prior periods (for example, due to changes in transaction price) for the years ended December 31, 2019 and 2018 .

Securities Available for Sale	Securities Available for Sale The Company’s Structured Program transactions include i) asset-backed securitization transactions and ii) Certificate Program transactions. Certificate Program transactions include CLUB Certificate and Levered Certificate transactions. In connection with asset-backed securitizations, the Company is the sponsor and establishes trusts to ultimately purchase the unsecured personal loans from the Company and/or third-party whole loan investors. Securities issued from our asset-backed securitizations are senior or subordinated based on the waterfall criteria of loan payments to each security class. The subordinated residual interests issued from these transactions are first to absorb credit losses in accordance with the waterfall criteria. The assets are transferred into a trust such that the assets are legally isolated from the creditors of the Company and are not available to satisfy obligations of the Company. These assets can only be used to settle obligations of the underlying trusts. The asset-backed securitization senior securities and subordinated residual interests retained by the Company are presented as “Asset-backed senior securities” and “Asset-backed subordinated securities,” respectively, in the securities available for sale tables below. In addition, the Company sponsors the sale of unsecured personal loans through the issuance of certificate securities under our Certificate Program. The certificate securities are collateralized by loans transferred to a series of a master trust and trade in the over-the-counter market with a CUSIP. The assets are transferred into a trust such that the assets are legally isolated from the creditors of the Company and are not available to satisfy obligations of the Company. These assets can only be used to settle obligations of the underlying Certificate Program trusts. The CLUB Certificate issued securities are pass-through securities of which each owner has an undivided and equal interest in the underlying loans of each transaction. The Levered Certificate issued securities include senior and subordinated securities based on the waterfall criteria of loan payments to each security class. The subordinated securities issued from these transactions are first to absorb credit losses in accordance with the waterfall criteria. The CLUB Certificate issued securities retained by the Company are presented as “CLUB Certificate asset-backed securities” in the securities available for sale tables below. The Levered Certificate issued senior and subordinated securities retained by the Company are presented in aggregate with securities from asset-backed securitizations as “Asset-backed senior securities” and “Asset-backed subordinated securities,” respectively, in the tables below.

LC Trust The Company established the LC Trust for the purpose of acquiring and holding loans for the sole benefit of certain investors that have purchased trust certificates issued by the LC Trust. The Company is obligated to ensure that the LC Trust meets minimum capital requirements with respect to funding the administrative activities and maintaining the operations of the LC Trust. Consolidated Trusts The Company establishes trusts to facilitate the sale of loans and issuance of senior and subordinated securities. If the Company is the primary beneficiary of the trust, it is a consolidated VIE and will reflect senior and subordinated securities held by third parties as a “Payable to securitization note and certificate holders” in the Company’s Consolidated Balance Sheets. If subsequently the Company is not the primary beneficiary of the trust, the Company will deconsolidate the VIE. See “ Note 2. Summary of Significant Accounting Policies ” and “ Note 14. Debt ” for additional information. Warehouse Credit Facilities The Company established certain entities (deemed to be VIEs) to enter into warehouse credit facilities for the purpose of purchasing loans from LendingClub. See “ Note 14.

Unconsolidated VIEs The Company’s transactions with unconsolidated VIEs include asset-backed securitizations, Certificate Program transactions and loan sale transactions of unsecured personal loans. The Company has various forms of involvement with VIEs, including servicing of loans and holding senior or subordinated residual interests in the VIEs. The accounting for these transactions is based on a primary beneficiary analysis to determine whether the underlying VIEs should be consolidated. If the VIEs are not consolidated and the transfer of the loans from the Company to the VIE meets sale accounting criteria, then the Company will recognize a gain or loss on sales of loans. The Company considers continued involvement in an unconsolidated VIE insignificant if it is the sponsor and servicer and does not hold other significant variable interests. In these instances, the Company’s involvement with the VIE is in the role as an agent and without significant participation in the economics of the VIE. The Company enters into separate servicing agreements with the VIEs and holds at least 5% of the beneficial interests issued by the VIEs to comply with regulatory risk retention rules. The beneficial interests retained by the Company consist of senior securities and subordinated securities and are accounted for as securities available for sale. In connection with these transactions, we make certain customary representations, warranties and covenants. See “ Note 2. Summary of Significant Accounting Policies ” for additional information. Investment Fund The Company has an equity investment in a private fund (Investment Fund) that participates in a family of funds with other unrelated third parties. This family of funds purchases whole loans and interests in loans from the Company, as well as other assets from third parties unrelated to the Company. As of December 31, 2019 , the Company had an ownership interest of approximately 23% in the Investment Fund. The Company’s investment is deemed to be a variable interest in the Investment Fund because the Company shares in the expected returns and losses of the Investment Fund. At December 31, 2019 , the Company’s investment was $7.7 million , which is recognized in “Other assets” on the Company’s Consolidated Balance Sheets . The following tables summarize unconsolidated VIEs with which the Company has significant continuing involvement, but is not the primary beneficiary at December 31, 2019 and 2018 : December 31, 2019 Carrying Value Total VIE Assets Securities Available for Sale Accrued Interest Receivable Other Assets Accrued Expenses and Other Liabilities Securities Sold Under Repurchase Agreements Net Assets Unconsolidated Trusts $ 1,909,219 $ 93,881 $ 362 $ 18,768 $ — $ — $ 113,011 Certificate Program 2,585,957 126,254 515 25,588 — — 152,357 Investment Fund 34,170 — — 7,742 — — 7,742 Total unconsolidated VIEs $ 4,529,346 $ 220,135 $ 877 $ 52,098 $ — $ — $ 273,110 December 31, 2019 Maximum Exposure to Loss Securities Available for Sale Accrued Interest Receivable Other Assets Accrued Expenses and Other Liabilities Securities Sold Under Repurchase Agreements Total Exposure Unconsolidated Trusts $ 93,881 $ 362 $ 18,768 $ — $ — $ 113,011 Certificate Program 126,254 515 25,588 — — 152,357 Investment Fund — — 7,742 — — 7,742 Total unconsolidated VIEs $ 220,135 $ 877 $ 52,098 $ — $ — $ 273,110 December 31, 2018 Carrying Value Total VIE Assets Securities Available for Sale Accrued Interest Receivable Other Assets Accrued Expenses and Other Liabilities Securities Sold Under Repurchase Agreements Net Assets Unconsolidated Trusts $ 1,359,367 $ 68,338 $ 958 $ 11,838 $ — $ (57,012 ) $ 24,122 Certificate Program 973,815 48,430 256 9,115 — — 57,801 Investment Fund 35,157 — — 8,253 — — 8,253 Total unconsolidated VIEs $ 2,368,339 $ 116,768 $ 1,214 $ 29,206 $ — $ (57,012 ) $ 90,176 December 31, 2018 Maximum Exposure to Loss Securities Available for Sale Accrued Interest Receivable Other Assets Accrued Expenses and Other Liabilities Securities Sold Under Repurchase Agreements Total Exposure Unconsolidated Trusts $ 68,339 $ 958 $ 11,838 $ — $ — $ 81,135 Certificate Program 48,431 256 9,115 — — 57,802 Investment Fund — — 8,253 — — 8,253 Total unconsolidated VIEs $ 116,770 $ 1,214 $ 29,206 $ — $ — $ 147,190 “Total VIE Assets” represents the remaining principal balance of loans held by unconsolidated VIEs with respect to Unconsolidated Trusts, Certificate Program transactions, and the net assets held by the Investment Fund using the most current information available. “Securities Available for Sale,” “Accrued Interest Receivable,” “Other Assets” and “Accrued Expenses and Other Liabilities” are the balances in the Company’s Consolidated Balance Sheets related to its involvement with the unconsolidated VIEs. “Other Assets” includes the Company’s servicing assets and servicing receivables and the Company’s equity investment with respect to the Investment Fund. “Total Exposure” refers to the Company’s maximum exposure to loss from its involvement with unconsolidated VIEs. It represents estimated loss that would be incurred under severe, hypothetical circumstances, for which the Company believes the possibility is extremely remote, such as where the value of interests and any associated collateral declines to zero. Accordingly, this required disclosure is not an indication of expected losses. The following table summarizes activity related to the unconsolidated trusts and Certificate Program trusts, with the transfers accounted for as a sale on the Company’s consolidated financial statements for the years ended December 31, 2019 and 2018 : Year Ended December 31, 2019 2018 Unconsolidated Trusts Unconsolidated Certificate Unconsolidated Trusts Unconsolidated Certificate Principal derecognized from loans securitized or sold $ 1,553,847 $ 2,868,709 $ 1,300,838 $ 1,145,616 Net gains (losses) recognized from loans securitized or sold $ 4,809 $ 32,417 $ 6,039 $ 10,483 Fair value of asset-backed senior and subordinated securities, and CLUB Certificate asset-backed securities retained upon settlement (1) $ 75,924 $ 140,825 $ 65,653 $ 56,764 Cash proceeds from loans securitized or sold $ 1,212,521 $ 2,555,713 $ 867,875 $ 1,088,212 Cash proceeds from servicing and other administrative fees on loans securitized or sold $ 16,961 $ 17,071 $ 13,725 $ 3,650 Cash proceeds for interest received on senior securities and subordinated securities $ 5,022 $ 7,717 $ 3,049 $ 1,747 (1) For Structured Program transactions, the Company retained asset-backed senior securities of $98.7 million and $57.3 million , CLUB Certificate asset-backed securities of $101.3 million and $56.8 million , and asset-backed subordinated securities of $16.8 million and $8.3 million for the years ended December 31, 2019 and 2018 , respectively. Off-Balance Sheet Loans Off-balance sheet loans primarily relate to Structured Program transactions for which the Company has some form of continuing involvement, including as servicer. Delinquent loans are comprised of loans 31 days or more past due, including non-accrual loans. For loans related to Structured Program transactions where servicing is the only form of continuing involvement, the Company would only experience a loss if it was required to repurchase a loan due to a breach in representations and warranties associated with its loan sale or servicing contracts. As of December 31, 2019 , the aggregate unpaid principal balance of the off-balance sheet loans pursuant to Structured Program transactions was $4.4 billion , of which $145.6 million was attributable to off-balance sheet loans that were 31 days or more past due. As of December 31, 2018 , the aggregate unpaid principal balance of the off-balance sheet loans pursuant to Structured Program transactions was $2.3 billion , of which $87.1 million was attributable to off-balance sheet loans that were 31 days or more past due. Retained Interests from Unconsolidated VIEs The Company and other investors in the subordinated interests issued by trusts and Certificate Program trusts have rights to cash flows only after the investors holding the senior securities issued by the trusts have first received their contractual cash flows. The investors and the trusts have no direct recourse to the Company’s assets, and holders of the securities issued by the trusts can look only to the assets of the trusts that issued their securities for payment. The beneficial interests held by the Company and the Company’s MOA are subject principally to the credit and prepayment risk stemming from the underlying unsecured personal whole loans. See “ Note 8. Fair Value of Assets and Liabilities ” for additional information on the fair value sensitivity of asset-backed securities related to Structured Program transactions. In October 2017, LendingClub Asset Management, LLC (LCAM), a wholly-owned subsidiary of LendingClub that previously acted as the general partner for certain private funds, initiated the wind-down of six funds by redeeming the LC Trust certificates issued to the funds and transferring the loan participations underlying the redeemed certificates to third party investors. Certain of the loan participations for two of the funds transferred did not meet the definition of participating interests because the Company provided a credit support agreement under which the investor has a recourse to the Company for credit losses. The transfer of these loan participations from these two funds was accounted for as a secured borrowing and the underlying whole loans were not derecognized from the Company’s Consolidated Balance Sheets . The Company elected the fair value option for the secured borrowings. As of December 31, 2019 , the fair value of the secured borrowings was $20.1 million , secured by loans at fair value of $18.0 million included in “Loans held for investment at fair value” in the Consolidated Balance Sheets . As of December 31, 2018 , the fair value of the secured borrowings was $80.6 million , secured by loans at fair value of $76.5 million included in “Loans held for investment at fair value” in the Consolidated Balance Sheets . Changes in the fair value of the secured borrowings are partially offset by the associated loan participations, and the net effect results in changes in fair value of the credit support agreement through earnings. As of December 31, 2019 and 2018 , the fair value of this credit support agreement was $2.2 million and $2.8 million , respectively. The fair value of the credit support agreement is equal to the present value of the probability-weighted estimate of expected payments over a range of loss scenarios. See “ Note 6. Loans Held for Investment, Loans Held for Sale, Notes, Certificates and Secured Borrowings ” for additional information.

Fair Value of Assets and Liabilities	Fair Value of Assets and Liabilities For a description of the fair value hierarchy and the Company’s fair value methodologies, see “ Note 2. Summary of Significant Accounting Policies . ” The Company records certain assets and liabilities at fair value as listed in the following tables. Financial Instruments, Assets and Liabilities Recorded at Fair Value The following tables present the fair value hierarchy for assets and liabilities measured at fair value at December 31, 2019 and 2018 : December 31, 2019 Level 1 Inputs Level 2 Inputs Level 3 Inputs Balance at Fair Value Assets: Loans held for investment $ — $ — $ 1,079,315 $ 1,079,315 Loans held for investment by the Company — — 43,693 43,693 Loans held for sale by the Company — — 722,355 722,355 Securities available for sale: Asset-backed senior securities and subordinated securities — 109,339 21,090 130,429 CLUB Certificate asset-backed securities — — 89,706 89,706 Corporate debt securities — 14,343 — 14,343 Certificates of deposit 13,100 — 13,100 Other asset-backed securities — 12,080 — 12,080 Commercial paper — 9,274 — 9,274 U.S. agency securities — 1,995 — 1,995 Total securities available for sale — 160,131 110,796 270,927 Servicing assets — — 89,680 89,680 Total assets $ — $ 160,131 $ 2,045,839 $ 2,205,970 Liabilities: Notes, certificates and secured borrowings $ — $ — $ 1,081,466 $ 1,081,466 Payable to securitization note and certificate holders — — 40,610 40,610 Loan trailing fee liability — — 11,099 11,099 Total liabilities $ — $ — $ 1,133,175 $ 1,133,175 December 31, 2018 Level 1 Inputs Level 2 Inputs Level 3 Inputs Balance at Fair Value Assets: Loans held for investment $ — $ — $ 1,883,251 $ 1,883,251 Loans held for investment by the Company — — 2,583 2,583 Loans held for sale by the Company — — 840,021 840,021 Securities available for sale: Asset-backed senior securities and subordinated securities — 56,489 11,849 68,338 Certificates of deposit — 14,929 — 14,929 Corporate debt securities — 17,328 — 17,328 Other asset-backed securities — 11,225 — 11,225 Commercial paper — 9,720 — 9,720 CLUB Certificate asset-backed securities — — 48,430 48,430 Other securities — 499 — 499 Total securities available for sale — 110,190 60,279 170,469 Servicing assets — — 64,006 64,006 Total assets $ — $ 110,190 $ 2,850,140 $ 2,960,330 Liabilities: Note, certificates and secured borrowings $ — $ — $ 1,905,875 $ 1,905,875 Loan trailing fee liability — — 10,010 10,010 Total liabilities $ — $ — $ 1,915,885 $ 1,915,885 As presented in the tables above, the Company has elected the fair value option for certain liabilities. Changes in the fair value of these financial liabilities caused by a change in the Company’s risk are reported in other comprehensive income (OCI). For the year ended December 31, 2019 , the amount reported in OCI is zero because these financial liabilities are either payable only upon receipt of cash flows from underlying loans or secured by cash collateral. Financial instruments are categorized in the valuation hierarchy based on the significance of unobservable factors in the overall fair value measurement. Since the Company’s loans held for investment and related notes, certificates and secured borrowings, loans held for sale, loan servicing rights, asset-backed securities related to Structured Program transactions, and loan trailing fee liability do not trade in an active market with readily observable prices, the Company uses significant unobservable inputs to measure the fair value of these assets and liabilities. These fair value estimates may also include observable, actively quoted components derived from external sources. As a result, changes in fair value for assets and liabilities within the Level 2 or Level 3 categories may include changes in fair value that were attributable to observable and unobservable inputs, respectively. The Company primarily uses a discounted cash flow model to estimate the fair value of Level 3 instruments based on the present value of estimated future cash flows. This model uses inputs that are inherently judgmental and reflect our best estimates of the assumptions a market participant would use to calculate fair value. The Company did not transfer any assets or liabilities in or out of Level 3 during the years ended December 31, 2019 or 2018 . Fair valuation adjustments are recorded through earnings related to Level 3 instruments for the years ended December 31, 2019 and 2018 . Certain unobservable inputs may (in isolation) have either a directionally consistent or opposite impact on the fair value of the financial instrument for a given change in that input. When multiple inputs are used within the valuation techniques, a change in one input in a certain direction may be offset by an opposite change from another input. Loans Held for Investment, Notes, Certificates and Secured Borrowings Significant Unobservable Inputs The following table presents quantitative information about the significant unobservable inputs used for the Company’s Level 3 fair value measurements for loans held for investment, notes, certificates and secured borrowings at December 31, 2019 and 2018 : Loans Held for Investment, Notes, Certificates and Secured Borrowings December 31, 2019 December 31, 2018 Minimum Maximum Weighted- Average Minimum Maximum Weighted- Average Discount rates 6.0 % 12.0 % 7.9 % 6.3 % 16.4 % 9.1 % Net cumulative expected loss rates (1) 3.6 % 34.9 % 11.9 % 2.8 % 36.9 % 12.8 % Cumulative expected prepayment rates (1) 28.7 % 38.6 % 31.7 % 27.8 % 40.3 % 31.2 % (1) Expressed as a percentage of the original principal balance of the loan, note, certificate or secured borrowing. Significant Recurring Level 3 Fair Value Input Sensitivity At December 31, 2019 and 2018 , the discounted cash flow methodology used to estimate the note, certificate and secured borrowings’ fair values used the same projected net cash flows as their related loans. As demonstrated by the following tables, the fair value adjustments for loans held for investment and loans held for sale were largely offset by the corresponding fair value adjustments due to the payment dependent design of the notes, certificates and secured borrowings.

Debt Disclosure [Abstract]
Debt	Debt Credit Facilities and Securities Sold Under Repurchase Agreements The Company may enter into arrangements in the ordinary course of business pursuant to which the Company can incur indebtedness. Below is a description of certain of these arrangements: Warehouse Credit Facilities Through wholly-owned subsidiaries, the Company entered into secured warehouse credit facilities (Warehouse Facilities) with certain lenders from 2017 to 2019 to finance the Company’s personal loans and auto refinance loans and to pay fees and expenses related to the applicable facilities. Each subsidiary entered into a credit agreement and security agreement with a commercial bank as administrative agent and a national banking association as collateral trustee and paying agent. As of December 31, 2019, the warehouse facilities used to finance our personal loans (Personal Loan Warehouse Credit Facilities) have a combined borrowing capacity of $750.0 million (which will be reduced to $700.0 million on January 15, 2020) on a revolving basis and have “Commitment Termination Dates” ranging from March 2020 to October 2020, at which point the Company’s ability to borrow additional funds ends. Under the respective agreements, if not amended, extended, or replaced, any outstanding debt on the Commitment Termination Dates would be repaid as an amortizing term loan until the facility’s final maturity date. The Company is working to amend and extend the Commitment Termination Dates of these Personal Loan Warehouse Credit Facilities. The final maturity date occurs at the earlier of twelve months after the Commitment Termination Date and three years after these Personal Loan Warehouse Credit Facilities were executed, and any remaining debt is due in full at such time. Under the respective agreements, the Personal Loan Warehouse Credit Facilities mature between January 2021 and March 2022. The warehouse facility to finance auto refinance loans (Auto Loan Warehouse Credit Facility) is a $34.2 million term loan that matures in June 2021, which has an outstanding balance of $14.3 million as of December 31, 2019. The amount borrowed under this Auto Loan Warehouse Credit Facility amortizes over time through regular principal and interest payments collected from the auto refinance loans that serve as collateral. The creditors of the Personal Loan and Auto Loan Warehouse Credit Facilities have no recourse to the general credit of the Company. Borrowings under these facilities bear interest at an annual benchmark rate of LIBOR (London Inter-bank Offered Rate) or at an alternative commercial paper rate (which is either (i) the per annum rate equivalent to the weighted-average of the per annum rates at which all commercial paper notes were issued by certain lenders to fund advances or maintain loans, or (ii) the daily weighted-average of LIBOR, as set forth in the applicable credit agreement), plus a spread ranging from 1.85% to 2.50% . Interest is payable monthly. Borrowings may be prepaid without penalty. In addition, the Personal Loan Warehouse Credit Facilities require payment of a monthly unused commitment fee ranging from 0.375% to 1.25% per annum on the average undrawn portion available. The Personal Loan and Auto Loan Warehouse Credit Facilities contain certain covenants. As of December 31, 2019 , the Company was in material compliance with all applicable covenants under the respective credit agreements. As of December 31, 2019 and 2018 , the Company had $387.3 million and $306.8 million in aggregate debt outstanding under the Personal Loan and Auto Loan Warehouse Credit Facilities, respectively, with collateral consisting of loans at fair value of $551.5 million and $453.0 million included in “Loans held for sale by the Company at fair value,” respectively, and restricted cash of $25.1 million and $25.2 million included in the Consolidated Balance Sheets , respectively. Revolving Credit Facility In December 2015, the Company entered into a credit and guaranty agreement and a pledge and security agreement with several lenders and a financial services company, as collateral agent, for an aggregate $120.0 million secured revolving credit facility (Revolving Facility). The Company may borrow under the Revolving Facility until December 17, 2020 . Repayment of any outstanding proceeds are payable on December 17, 2020 , but may be prepaid without penalty. Borrowings under the Revolving Facility bear interest, at the Company’s option, at an annual rate of LIBOR plus a spread of 1.75% to 2.00% , which is fixed for a Company-selected interest period of one, two, three, six or twelve months, or at an alternative base rate (which is tied to either the prime rate, federal funds effective rate plus 0.50% , or the adjusted eurocurrency rate plus 1.00% , as defined in the credit agreement) plus a spread of 0.75% to 1.00% . Base rate borrowings may be prepaid at any time without penalty, however pre-payment of LIBOR-based borrowings before the end of the selected interest period may result in the Company incurring expense to compensate the lenders for their funding costs through the end of the interest period. Interest is payable quarterly. Additionally, the Company is required to pay a quarterly commitment fee to the lenders of between 0.25% and 0.375% per annum, depending on the Company’s total net leverage ratio, on the average undrawn portion available under the Revolving Facility. The Revolving Facility contains certain covenants. As of December 31, 2019 , the Company was in material compliance with all applicable covenants in the credit and guaranty agreement. The Company had $60.0 million and $95.0 million in debt outstanding under the Revolving Facility as of December 31, 2019 and 2018 , respectively. Repurchase Agreements In 2018 and 2019, the Company entered into repurchase agreements pursuant to which the Company may sell securities (subject to an obligation to repurchase such securities at a specified future date and price) in exchange for cash, primarily to finance securities retained from the Company’s Structured Program transactions. The Company is subject to margin calls based on the fair value of the securities to be repurchased. As of December 31, 2019 and 2018 , the Company had $140.2 million and $57.0 million in aggregate debt outstanding under its repurchase agreements, respectively, of which, at December 31, 2019, $64.5 million had contractual repurchase dates ranging from February 2020 to December 2026 and $75.7 million is subject to a repurchase date in March 2020 that requires counterparty approval to extend such repurchase date. The contractual repurchase dates correspond to either a set repurchase schedule or to the maturity dates of the underlying securities, which have a weighted-average estimated life from 1.1 to 1.4 years . The repurchase agreements bear interest at a rate that is based on a benchmark of the three-month LIBOR rate or the weighted-average interest rate of the securities sold plus a spread of 0.65% to 2.50% . Securities sold are included in “Credit facilities and securities sold under repurchase agreements” on the Consolidated Balance Sheets . As of December 31, 2019 and 2018 , the Company had $174.8 million and $64.1 million , respectively, of underlying assets sold under repurchase agreements. Payable to Securitization Note and Certificate Holders In November 2019, the Company sponsored a securitization transaction through a master trust consisting of $44.7 million in unsecured personal whole loans. The trust sold certificate participations to third-party investors in an amount equal to 95% of the loans for $42.5 million in net proceeds. The remaining certificate participations and the residual interest were retained by the Company. The Company is the primary beneficiary of the trust, which is consolidated. As of December 31, 2019, the certificate participations held by third-party investors of $40.6 million are included in “Payable to securitization note and certificate holders” in the Consolidated Balance Sheets and were secured by loans held for investment by the Company at fair value of $40.3 million and restricted cash of $2.9 million included in the Consolidated Balance Sheets . As of December 31, 2018 , the Company was the primary beneficiary of a securitization trust that was consolidated. The notes held by third-party investors and the related unamortized debt issuance costs of $256.4 million are included in “Payable to securitization note and certificate holders” in the Consolidated Balance Sheets and were secured by loans held for sale by the Company at fair value of $286.3 million and restricted cash of $9.3 million included in the Consolidated Balance Sheets . In May 2019, the Company sold a portion of the residual certificates and no longer holds significant variable interest in the securitization trust. As a result, the Company deconsolidated the securitization trust, including the derecognition of the payable to securitization note holders.

Secured Borrowings	Securitizations and Variable Interest Entities VIE Assets and Liabilities The following tables provide the classifications of assets and liabilities on the Company’s Consolidated Balance Sheets for its transactions with consolidated and unconsolidated VIEs at December 31, 2019 and 2018 . Additionally, the assets and liabilities in the tables below exclude intercompany balances that eliminate in consolidation: December 31, 2019 Consolidated VIEs Unconsolidated VIEs Total Assets Restricted cash $ 30,046 $ — $ 30,046 Securities available for sale at fair value — 220,135 220,135 Loans held for investment at fair value 197,842 — 197,842 Loans held for investment by the Company at fair value 40,251 — 40,251 Loans held for sale by the Company at fair value 551,455 — 551,455 Accrued interest receivable 4,431 877 5,308 Other assets 1,359 52,098 53,457 Total assets $ 825,384 $ 273,110 $ 1,098,494 Liabilities Accrued interest payable $ 3,185 $ — $ 3,185 Accrued expenses and other liabilities 244 — 244 Notes, certificates and secured borrowings at fair value 197,842 — 197,842 Credit facilities and securities sold under repurchase agreements 387,251 — 387,251 Payable to securitization note and certificate holders at fair value 40,610 — 40,610 Total liabilities 629,132 — 629,132 Total net assets $ 196,252 $ 273,110 $ 469,362 December 31, 2018 Consolidated VIEs Unconsolidated VIEs Total Assets Restricted cash $ 43,918 $ — $ 43,918 Securities available for sale at fair value — 116,768 116,768 Loans held for investment at fair value 642,094 — 642,094 Loans held for sale by the Company at fair value 739,216 — 739,216 Accrued interest receivable 10,438 1,214 11,652 Other assets 2,498 29,206 31,704 Total assets $ 1,438,164 $ 147,188 $ 1,585,352 Liabilities Accrued interest payable $ 7,594 $ — $ 7,594 Accrued expenses and other liabilities 1,627 — 1,627 Notes, certificates and secured borrowings at fair value 648,908 — 648,908 Payable to securitization note and certificate holders 256,354 — 256,354 Credit facilities and securities sold under repurchase agreements 306,790 57,012 363,802 Total liabilities 1,221,273 57,012 1,278,285 Total net assets $ 216,891 $ 90,176 $ 307,067 Consolidated VIEs The Company consolidates VIEs when it is deemed to be the primary beneficiary. See “ Note 2. Summary of Significant Accounting Policies ” for additional information. LC Trust The Company established the LC Trust for the purpose of acquiring and holding loans for the sole benefit of certain investors that have purchased trust certificates issued by the LC Trust. The Company is obligated to ensure that the LC Trust meets minimum capital requirements with respect to funding the administrative activities and maintaining the operations of the LC Trust. Consolidated Trusts The Company establishes trusts to facilitate the sale of loans and issuance of senior and subordinated securities. If the Company is the primary beneficiary of the trust, it is a consolidated VIE and will reflect senior and subordinated securities held by third parties as a “Payable to securitization note and certificate holders” in the Company’s Consolidated Balance Sheets. If subsequently the Company is not the primary beneficiary of the trust, the Company will deconsolidate the VIE. See “ Note 2. Summary of Significant Accounting Policies ” and “ Note 14. Debt ” for additional information. Warehouse Credit Facilities The Company established certain entities (deemed to be VIEs) to enter into warehouse credit facilities for the purpose of purchasing loans from LendingClub. See “ Note 14. Debt ” for additional information. The following table presents a summary of financial assets and liabilities from the Company’s involvement with consolidated VIEs at December 31, 2019 and 2018 : December 31, 2019 Assets Liabilities Net Assets LC Trust $ 201,696 $ (199,520 ) $ 2,176 Consolidated Trusts 43,300 (40,687 ) 2,613 Warehouse credit facilities 580,388 (388,925 ) 191,463 Total consolidated VIEs $ 825,384 $ (629,132 ) $ 196,252 December 31, 2018 Assets Liabilities Net Assets LC Trust $ 657,339 $ (656,088 ) $ 1,251 Consolidated Trusts 297,821 (256,901 ) 40,920 Warehouse credit facility 483,004 (308,284 ) 174,720 Total consolidated VIEs $ 1,438,164 $ (1,221,273 ) $ 216,891 The creditors of the VIEs above have no recourse to the general credit of the Company as the primary beneficiary of the VIEs and the liabilities of the VIEs can only be settled by the respective VIE’s assets. Unconsolidated VIEs The Company’s transactions with unconsolidated VIEs include asset-backed securitizations, Certificate Program transactions and loan sale transactions of unsecured personal loans. The Company has various forms of involvement with VIEs, including servicing of loans and holding senior or subordinated residual interests in the VIEs. The accounting for these transactions is based on a primary beneficiary analysis to determine whether the underlying VIEs should be consolidated. If the VIEs are not consolidated and the transfer of the loans from the Company to the VIE meets sale accounting criteria, then the Company will recognize a gain or loss on sales of loans. The Company considers continued involvement in an unconsolidated VIE insignificant if it is the sponsor and servicer and does not hold other significant variable interests. In these instances, the Company’s involvement with the VIE is in the role as an agent and without significant participation in the economics of the VIE. The Company enters into separate servicing agreements with the VIEs and holds at least 5% of the beneficial interests issued by the VIEs to comply with regulatory risk retention rules. The beneficial interests retained by the Company consist of senior securities and subordinated securities and are accounted for as securities available for sale. In connection with these transactions, we make certain customary representations, warranties and covenants. See “ Note 2. Summary of Significant Accounting Policies ” for additional information. Investment Fund The Company has an equity investment in a private fund (Investment Fund) that participates in a family of funds with other unrelated third parties. This family of funds purchases whole loans and interests in loans from the Company, as well as other assets from third parties unrelated to the Company. As of December 31, 2019 , the Company had an ownership interest of approximately 23% in the Investment Fund. The Company’s investment is deemed to be a variable interest in the Investment Fund because the Company shares in the expected returns and losses of the Investment Fund. At December 31, 2019 , the Company’s investment was $7.7 million , which is recognized in “Other assets” on the Company’s Consolidated Balance Sheets . The following tables summarize unconsolidated VIEs with which the Company has significant continuing involvement, but is not the primary beneficiary at December 31, 2019 and 2018 : December 31, 2019 Carrying Value Total VIE Assets Securities Available for Sale Accrued Interest Receivable Other Assets Accrued Expenses and Other Liabilities Securities Sold Under Repurchase Agreements Net Assets Unconsolidated Trusts $ 1,909,219 $ 93,881 $ 362 $ 18,768 $ — $ — $ 113,011 Certificate Program 2,585,957 126,254 515 25,588 — — 152,357 Investment Fund 34,170 — — 7,742 — — 7,742 Total unconsolidated VIEs $ 4,529,346 $ 220,135 $ 877 $ 52,098 $ — $ — $ 273,110 December 31, 2019 Maximum Exposure to Loss Securities Available for Sale Accrued Interest Receivable Other Assets Accrued Expenses and Other Liabilities Securities Sold Under Repurchase Agreements Total Exposure Unconsolidated Trusts $ 93,881 $ 362 $ 18,768 $ — $ — $ 113,011 Certificate Program 126,254 515 25,588 — — 152,357 Investment Fund — — 7,742 — — 7,742 Total unconsolidated VIEs $ 220,135 $ 877 $ 52,098 $ — $ — $ 273,110 December 31, 2018 Carrying Value Total VIE Assets Securities Available for Sale Accrued Interest Receivable Other Assets Accrued Expenses and Other Liabilities Securities Sold Under Repurchase Agreements Net Assets Unconsolidated Trusts $ 1,359,367 $ 68,338 $ 958 $ 11,838 $ — $ (57,012 ) $ 24,122 Certificate Program 973,815 48,430 256 9,115 — — 57,801 Investment Fund 35,157 — — 8,253 — — 8,253 Total unconsolidated VIEs $ 2,368,339 $ 116,768 $ 1,214 $ 29,206 $ — $ (57,012 ) $ 90,176 December 31, 2018 Maximum Exposure to Loss Securities Available for Sale Accrued Interest Receivable Other Assets Accrued Expenses and Other Liabilities Securities Sold Under Repurchase Agreements Total Exposure Unconsolidated Trusts $ 68,339 $ 958 $ 11,838 $ — $ — $ 81,135 Certificate Program 48,431 256 9,115 — — 57,802 Investment Fund — — 8,253 — — 8,253 Total unconsolidated VIEs $ 116,770 $ 1,214 $ 29,206 $ — $ — $ 147,190 “Total VIE Assets” represents the remaining principal balance of loans held by unconsolidated VIEs with respect to Unconsolidated Trusts, Certificate Program transactions, and the net assets held by the Investment Fund using the most current information available. “Securities Available for Sale,” “Accrued Interest Receivable,” “Other Assets” and “Accrued Expenses and Other Liabilities” are the balances in the Company’s Consolidated Balance Sheets related to its involvement with the unconsolidated VIEs. “Other Assets” includes the Company’s servicing assets and servicing receivables and the Company’s equity investment with respect to the Investment Fund. “Total Exposure” refers to the Company’s maximum exposure to loss from its involvement with unconsolidated VIEs. It represents estimated loss that would be incurred under severe, hypothetical circumstances, for which the Company believes the possibility is extremely remote, such as where the value of interests and any associated collateral declines to zero. Accordingly, this required disclosure is not an indication of expected losses. The following table summarizes activity related to the unconsolidated trusts and Certificate Program trusts, with the transfers accounted for as a sale on the Company’s consolidated financial statements for the years ended December 31, 2019 and 2018 : Year Ended December 31, 2019 2018 Unconsolidated Trusts Unconsolidated Certificate Unconsolidated Trusts Unconsolidated Certificate Principal derecognized from loans securitized or sold $ 1,553,847 $ 2,868,709 $ 1,300,838 $ 1,145,616 Net gains (losses) recognized from loans securitized or sold $ 4,809 $ 32,417 $ 6,039 $ 10,483 Fair value of asset-backed senior and subordinated securities, and CLUB Certificate asset-backed securities retained upon settlement (1) $ 75,924 $ 140,825 $ 65,653 $ 56,764 Cash proceeds from loans securitized or sold $ 1,212,521 $ 2,555,713 $ 867,875 $ 1,088,212 Cash proceeds from servicing and other administrative fees on loans securitized or sold $ 16,961 $ 17,071 $ 13,725 $ 3,650 Cash proceeds for interest received on senior securities and subordinated securities $ 5,022 $ 7,717 $ 3,049 $ 1,747 (1) For Structured Program transactions, the Company retained asset-backed senior securities of $98.7 million and $57.3 million , CLUB Certificate asset-backed securities of $101.3 million and $56.8 million , and asset-backed subordinated securities of $16.8 million and $8.3 million for the years ended December 31, 2019 and 2018 , respectively. Off-Balance Sheet Loans Off-balance sheet loans primarily relate to Structured Program transactions for which the Company has some form of continuing involvement, including as servicer. Delinquent loans are comprised of loans 31 days or more past due, including non-accrual loans. For loans related to Structured Program transactions where servicing is the only form of continuing involvement, the Company would only experience a loss if it was required to repurchase a loan due to a breach in representations and warranties associated with its loan sale or servicing contracts. As of December 31, 2019 , the aggregate unpaid principal balance of the off-balance sheet loans pursuant to Structured Program transactions was $4.4 billion , of which $145.6 million was attributable to off-balance sheet loans that were 31 days or more past due. As of December 31, 2018 , the aggregate unpaid principal balance of the off-balance sheet loans pursuant to Structured Program transactions was $2.3 billion , of which $87.1 million was attributable to off-balance sheet loans that were 31 days or more past due. Retained Interests from Unconsolidated VIEs The Company and other investors in the subordinated interests issued by trusts and Certificate Program trusts have rights to cash flows only after the investors holding the senior securities issued by the trusts have first received their contractual cash flows. The investors and the trusts have no direct recourse to the Company’s assets, and holders of the securities issued by the trusts can look only to the assets of the trusts that issued their securities for payment. The beneficial interests held by the Company and the Company’s MOA are subject principally to the credit and prepayment risk stemming from the underlying unsecured personal whole loans. See “ Note 8. Fair Value of Assets and Liabilities ” for additional information on the fair value sensitivity of asset-backed securities related to Structured Program transactions. In October 2017, LendingClub Asset Management, LLC (LCAM), a wholly-owned subsidiary of LendingClub that previously acted as the general partner for certain private funds, initiated the wind-down of six funds by redeeming the LC Trust certificates issued to the funds and transferring the loan participations underlying the redeemed certificates to third party investors. Certain of the loan participations for two of the funds transferred did not meet the definition of participating interests because the Company provided a credit support agreement under which the investor has a recourse to the Company for credit losses. The transfer of these loan participations from these two funds was accounted for as a secured borrowing and the underlying whole loans were not derecognized from the Company’s Consolidated Balance Sheets . The Company elected the fair value option for the secured borrowings. As of December 31, 2019 , the fair value of the secured borrowings was $20.1 million , secured by loans at fair value of $18.0 million included in “Loans held for investment at fair value” in the Consolidated Balance Sheets . As of December 31, 2018 , the fair value of the secured borrowings was $80.6 million , secured by loans at fair value of $76.5 million included in “Loans held for investment at fair value” in the Consolidated Balance Sheets . Changes in the fair value of the secured borrowings are partially offset by the associated loan participations, and the net effect results in changes in fair value of the credit support agreement through earnings. As of December 31, 2019 and 2018 , the fair value of this credit support agreement was $2.2 million and $2.8 million , respectively. The fair value of the credit support agreement is equal to the present value of the probability-weighted estimate of expected payments over a range of loss scenarios. See “ Note 6. Loans Held for Investment, Loans Held for Sale, Notes, Certificates and Secured Borrowings ” for additional information.

In 2016, the board of directors approved incentive retention awards to certain members of the executive management team and other key personnel. These incentive awards consisted of an aggregate of $16.3 million of RSUs and $18.6 million of cash. These incentive retention awards were recognized as compensation expense ratably through May 2017. Restricted Stock Units The following table summarizes the activities for the Company’s RSUs during the year ended December 31, 2019 : Number of Units (1) Weighted- Average Grant Date Fair Value (1) Unvested at December 31, 2018 8,639,802 $ 20.23 Granted 7,531,283 $ 15.23 Vested (3,545,198 ) $ 20.43 Forfeited/expired (3,028,483 ) $ 18.49 Unvested at December 31, 2019 9,597,404 $ 16.78 (1) Amounts have been retroactively adjusted to reflect a reverse stock split. See “ Note 4. Net Loss Per Share ” for additional information. During the year ended December 31, 2019 , the Company granted 7,531,283 RSUs with an aggregate fair value of $114.7 million . As of December 31, 2019 , there was $151.0 million of unrecognized compensation cost related to unvested RSUs, which is expected to be recognized over the next 2.8 years. Performance-based Restricted Stock Units PBRSUs are equity awards that are earned, and eligible for time-based vesting, based upon the achievement of certain pre-established performance metrics over a specific performance period. Depending on the level of achievement of the pre-established performance targets, the PBRSUs earned and eligible for time-based vesting can range from 0% to 200% of the target amount. PBRSUs granted under the Company’s EIP generally have a one -year performance period with the earned shares, if any, vesting over an additional approximately two -year period. Over the performance period, the number of PBRSUs that may be earned and the related stock-based compensation expense that is recognized is adjusted upward or downward based upon the probability of achieving the pre-established performance metrics. During the first quarter of 2019 , the Company expanded the use of its PBRSU program to nearly all of the executive team. The following table summarizes the activities for the Company’s PBRSUs during the year ended December 31, 2019 : Number of Units (1) Weighted- Average Grant Date Fair Value (1) Unvested at December 31, 2018 254,643 $ 18.54 Granted 373,810 $ 16.42 Vested (97,776 ) $ 18.91 Forfeited/expired (2) (59,088 ) $ 17.32 Unvested at December 31, 2019 471,589 $ 16.94 (1) Amounts have been retroactively adjusted to reflect a reverse stock split. See “ Note 4. Net Loss Per Share ” for additional information. (2) Represents the portion of PBRSUs granted in 2018 that were unearned as a result of not achieving certain pre-established performance metrics during the performance period. For the years ended December 31, 2019 , 2018 and 2017 , the Company recognized $3.9 million , $2.8 million and $1.0 million in stock-based compensation expense related to these PBRSUs, respectively. As of December 31, 2019 , there was $3.3 million of unrecognized compensation cost related to unvested PBRSUs, which is expected to be recognized over the next 1.7 years . Stock Options The following table summarizes the activities for the Company’s stock options during 2019 : Number of Options (1) Weighted-Average Exercise Price Per Share (1) Weighted-Average Remaining Contractual Life (in years) Aggregate Intrinsic Value (2) (in thousands) Outstanding at December 31, 2018 3,152,929 $ 25.80 Granted — $ — Exercised (470,666 ) $ 1.85 Forfeited/Expired (427,375 ) $ 33.74 Outstanding at December 31, 2019 2,254,888 $ 29.27 4.2 $ 5,528 Exercisable at December 31, 2019 2,193,730 $ 29.16 4.1 $ 5,528 (1) Amounts have been retroactively adjusted to reflect a reverse stock split. See “ Note 4. Net Loss Per Share ” for additional information. (2) The aggregate intrinsic value is calculated as the difference between the exercise price of the underlying awards and the Company’s closing stock price of $12.62 as reported on the New York Stock Exchange on December 31, 2019 . The aggregate intrinsic value of options exercised was $5.9 million , $1.9 million and $27.0 million for the years ended December 31, 2019 , 2018 and 2017 , respectively. The total fair value of stock options vested for the years ended December 31, 2019 , 2018 and 2017 was $2.8 million , $9.8 million and $19.6 million , respectively. As of December 31, 2019 , the total unrecognized compensation cost related to outstanding stock options was $0.8 million , which is expected to be recognized over the next 0.5 years. There were no stock options granted during the years ended December 31, 2019 , 2018 and 2017 . Employee Stock Purchase Plan The Company’s employee stock purchase plan (ESPP) became effective on December 11, 2014 . The Company’s ESPP allowed eligible employees to purchase shares of the Company’s common stock at a discount through payroll deductions, subject to plan limitations. Payroll deductions were accumulated during six-month offering periods. The purchase price for each share of common stock was 85% of the lower of the fair market value of the common stock on the first business day of the offering period or on the last business day of the offering period. In connection with the Company’s cost structure simplification efforts, future purchases through the Company’s ESPP were suspended effective upon the completion of the most recent offering period on May 10, 2019. The Company’s employees purchased 163,970 , 361,840 and 261,907 shares of common stock under the ESPP during the years ended December 31, 2019 , 2018 and 2017 , respectively. As of December 31, 2019 , 2018 and 2017 , a total of 3,123,203 , 2,307,400 and 1,739,199 shares remain reserved for future issuance, respectively. The fair value of stock purchase rights granted to employees under the ESPP was measured on the grant date using the Black-Scholes option pricing model. The compensation expense related to ESPP purchase rights was recognized on a straight-line basis over the six -month requisite service period. We used the following assumptions in estimating the fair value of the grants under the ESPP, which were derived using the same methodology applied to stock option assumptions: Year Ended December 31, 2018 2017 Expected dividend yield — — Weighted-average assumed stock price volatility 54.6 % 45.1 % Weighted-average risk-free interest rate 2.29 % 1.21 % Weighted-average expected life (in years) 0.50 0.50 For the years ended December 31, 2018 and 2017 , the dates of the assumptions were May 11, 2018 and November 11, 2018 and May 11, 2017 and November 11, 2017, respectively. There were no dates of assumption under the ESPP in 2019. Retirement Plan Upon completing 90 days of service, employees may participate in the Company’s qualified retirement plan that is governed by section 401(k) of the IRS Code. Participants may elect to contribute a portion of their annual compensation up to the maximum limit allowed by federal tax law. In the first quarter of 2016, the Company approved an employer match of up to 4% of an employee’s eligible compensation with a maximum annual match of $5,000 per employee. The total expense for the employer match for the years ended December 31, 2019 , 2018 and 2017 was $4.5 million , $5.0 million and $4.4 million , respectively. Stock Issued Related to Acquisition As part of the Springstone acquisition in 2014, the sellers received shares of the Company’s Series F convertible preferred stock having an aggregate value of $25.0 million (Share Consideration). $22.1 million of the Share Consideration was subject to certain vesting and forfeiture conditions over a three -year period for key continuing employees. This was accounted for as a compensation agreement and expensed over the three -year vesting period. In conjunction with the conversion of preferred stock upon the IPO, these preferred shares were converted into common shares.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Loss before income tax expense (benefit) less income (loss) attributable to noncontrolling interests was $(30.9) million , $(128.3) million and $(153.2) million for the years ended December 31, 2019 , 2018 and 2017 , respectively. Income tax expense (benefit) consisted of the following for the periods shown below: Year Ended December 31, 2019 2018 2017 Current: Federal $ (141 ) $ (57 ) $ 498 State (60 ) 100 134 Total current tax expense (benefit) $ (201 ) $ 43 $ 632 Deferred: Federal $ — $ — $ — State — — — Total deferred tax expense (benefit) $ — $ — $ — Income tax expense (benefit) $ (201 ) $ 43 $ 632 Income tax benefit and expense for the years ended December 31, 2019 and 2017 , respectively, were primarily attributable to the tax effects of unrealized gains recorded to other comprehensive income associated with the Company’s available for sale portfolio. Income tax expense for the year ended December 31, 2018 was primarily attributable to current state income taxes, partially offset by the tax effects of unrealized gains recorded to other comprehensive income associated with the Company’s available for sale portfolio. A reconciliation of the income taxes expected at the statutory federal income tax rate and income tax expense (benefit) for the years ended December 31, 2019 , 2018 and 2017 , is as follows: Year Ended December 31, 2019 2018 2017 Tax at federal statutory rate $ (6,499 ) $ (26,936 ) $ (52,089 ) State tax, net of federal tax benefit (60 ) 100 42 Stock-based compensation expense 4,773 6,559 3,171 Research and development tax credits (2,336 ) (7,839 ) (5,022 ) Change in valuation allowance (802 ) 19,140 (3,532 ) Change in unrecognized tax benefit 1,168 3,920 2,922 Tax rate change — — 53,048 Non-deductible expenses 3,250 5,143 2,212 Other 305 (44 ) (120 ) Income tax expense (benefit) $ (201 ) $ 43 $ 632 The significant components of the Company’s deferred tax assets and liabilities as of December 31, 2019 and 2018 were: December 31, 2019 2018 Deferred tax assets: Net operating loss carryforwards $ 118,090 $ 128,193 Stock-based compensation 11,480 11,434 Reserves and accruals 23,008 25,373 Operating lease liabilities 33,824 — Goodwill 19,818 21,580 Intangible assets 3,074 2,782 Tax credit carryforwards 16,679 14,363 Other 498 908 Total deferred tax assets 226,471 204,633 Valuation allowance (169,526 ) (169,291 ) Deferred tax assets – net of valuation allowance $ 56,945 $ 35,342 Deferred tax liabilities: Internally developed software $ (20,225 ) $ (21,813 ) Servicing fees (4,389 ) — Depreciation and amortization — (4,137 ) Operating lease assets (28,224 ) — Change in tax method (3,988 ) (7,349 ) Other (119 ) (2,043 ) Total deferred tax liabilities $ (56,945 ) $ (35,342 ) Deferred tax asset (liability) – net $ — $ — The Company continues to recognize a full valuation allowance against net deferred tax assets. This determination was based on the assessment of the available positive and negative evidence to estimate if sufficient future taxable income will be generated to utilize the existing deferred tax assets. As of December 31, 2019 and 2018 , the valuation allowance was $169.5 million and $169.3 million , respectively. As of December 31, 2019 , the Company had federal and state net operating loss (NOL) carryforwards of approximately $397.3 million and $442.3 million , respectively, to offset future taxable income. The federal and majority of state NOL carryforwards start expiring in 2026 and 2028 , respectively. Additionally, as of December 31, 2019 , the Company had federal and state research and development credit carryforwards of $16.3 million and $16.4 million , respectively. The federal research credit carryforwards will expire beginning in 2026 and the state research credits may be carried forward indefinitely . As of December 31, 2019 , the Company also had other state tax credit carryforwards of $2.2 million , which will expire beginning in 2020 . In general, a corporation’s ability to utilize its NOL and research and development credit carryforwards may be substantially limited due to the ownership change limitations as required by Section 382 and 383 of the Internal Revenue Code of 1986, as amended (Code), as well as similar state provisions. The federal and state Section 382 and 383 limitations may limit the use of a portion of the Company’s domestic NOL and tax credit carryforwards. Further, a portion of the carryforwards may expire before being applied to reduce future income tax liabilities. A reconciliation of the beginning and ending balance of total unrecognized tax benefits for the years ended December 31, 2019 , 2018 and 2017 , is as follows: Year Ended December 31, 2019 2018 2017 Beginning balance $ 13,377 $ 7,784 $ 3,246 Gross increase for tax positions related to prior years — 2,744 2,330 Gross increase for tax positions related to the current year 2,621 2,849 2,208 Ending balance $ 15,998 $ 13,377 $ 7,784 If the unrecognized tax benefit as of December 31, 2019 is recognized, there will be no effect on the Company’s effective tax rate as the tax benefit would increase a deferred tax asset, which is currently offset with a full valuation allowance. The Company recognizes interest and penalties related to unrecognized tax benefits within income tax expense. As of December 31, 2019 , the Company had no accrued interest and penalties related to unrecognized tax benefits. The Company does not expect any significant increases or decreases to its unrecognized benefits within the next twelve months. The Company files income tax returns in the United States and various state jurisdictions. As of December 31, 2019 , the Company’s federal tax returns for 2015 and earlier, and the state tax returns for 2014 and earlier were no longer subject to examination by the taxing authorities. However, tax periods closed in a prior period may be subject to audit and re-examination by tax authorities for which tax carryforwards are utilized in subsequent years.

Leases [Abstract]
Leases	Leases The Company has operating leases for its headquarters in San Francisco, California, as well as additional office space for its origination and servicing operations in the Salt Lake City area, Utah, and Westborough, Massachusetts. As of December 31, 2019 , the lease agreements have remaining lease terms ranging from approximately two years to ten years . Some of the lease agreements include options to extend the lease term for up to an additional fifteen years and some of them include options to terminate the lease with six months ’ prior notice. In addition, the Company is the sublessor of a portion of its office space in San Francisco, with lease terms ranging from two years to three years . As of December 31, 2019 , the Company pledged $0.9 million of cash and $5.5 million in letters of credit as security deposits in connection with its lease agreements. Balance sheet information as of December 31, 2019 related to leases was as follows: ROU Assets and Lease Liabilities December 31, 2019 Operating lease assets $ 93,485 Operating lease liabilities (1) $ 112,344 (1) The difference between operating lease assets and operating lease liabilities is the unamortized balance of deferred rent, which prior to January 1, 2019 was included as a separate liability within “Accrued expenses and other liabilities.” Components of net lease costs for the years ended December 31, 2019 , 2018 and 2017 , were as follows: Year Ended December 31, Net Lease Costs Income Statement Classification 2019 2018 2017 Operating lease costs (1) Other general and administrative expense $ (19,502 ) $ (17,183 ) $ (15,780 ) Sublease revenue Other revenue 4,637 397 391 Net lease costs $ (14,865 ) $ (16,786 ) $ (15,389 ) (1) Includes variable lease costs of $1.6 million , $0.6 million and $0.4 million for the years ended December 31, 2019 , 2018 and 2017 , respectively.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Operating Lease Commitments For discussion regarding the Company’s operating lease commitments, see “ Note 18. Leases . ” Loan Purchase Obligation Under the Company’s loan account program with WebBank, which serves as the Company’s primary issuing bank for loans facilitated through the Company’s platform, WebBank retains ownership of the loans it originates for two business days after origination. As part of this arrangement, the Company is committed to purchase the loans at par plus accrued interest, at the conclusion of the two business days. As of December 31, 2019 and 2018 , the Company was committed to purchase loans with an outstanding principal balance of $91.3 million and $55.9 million at par, respectively. Loan Repurchase Obligations The Company is generally required to repurchase loans or interests therein in the event of identity theft or certain other types of fraud on the part of the borrower or education and patient service providers. The Company may also repurchase loans or interests therein in connection with certain customer accommodations. In connection with certain whole loan and Certificate Program sales, as well as to facilitate access to securitization markets, the Company has agreed to repurchase loans if representations and warranties made with respect to such loans are breached under certain circumstances. In the case of certain securitization transactions, the Company has also agreed to repurchase or substitute loans for which a borrower fails to make the first payment due under a loan. The Company believes such provisions are customary and consistent with institutional loan and securitization market standards. In addition to and distinct from the repurchase obligations described in the preceding paragraph, the Company performs certain administrative functions for a variety of retail and institutional investors, including executing, without discretion, loan investments as directed by the investor. To the extent loans do not meet the investor’s investment criteria at the time of issuance, or are transferred to the investor as a result of a system error by the Company, the Company repurchases such loans or interests therein at par. As a result of the loan repurchase obligations described above, the Company repurchased $5.5 million , $4.0 million and $2.2 million in loans or interests therein during 2019 , 2018 and 2017 respectively. Purchase Commitments As required by applicable regulations, the Company must make firm offers of credit with respect to prescreened direct mail it sends out to prospective applicants provided such applicants continue to meet the credit worthiness criteria which were used to screen them at the time of their application. If such loans are accepted by the applicants but not otherwise funded by investors on the platform, the Company is required to facilitate funding for the loans directly with its issuing bank partners. The Company was not required to purchase any such loans during 2019 . Additionally, loans in the process of being facilitated through the Company’s platform and originated by the Company’s issuing bank partner at December 31, 2019 , were substantially funded in January 2020 . As of the date of this Report, no loans remained without investor commitments and the Company was not required to purchase any of these loans. In addition, if neither the Company nor Springstone can arrange for other investors to invest in or purchase loans that Springstone facilitates and that are originated by an issuing bank partner but do not meet the credit criteria for purchase by the issuing bank partner, the Company and Springstone are contractually committed to purchase these loans. As of December 31, 2019 and 2018 , the Company had a $9.0 million deposit in a bank account to secure potential future purchases of these loans, if necessary. The funds are recorded as restricted cash on the Company’s Consolidated Balance Sheets . During the year ended December 31, 2019 , the Company was required to purchase $45.3 million of loans facilitated by Springstone. These purchased loans are held on the Company’s Consolidated Balance Sheets and have a fair value of $45.7 million and $26.6 million as of December 31, 2019 and 2018 , respectively. The Company believes it will be required to purchase additional loans facilitated by Springstone in 2020 as it seeks to arrange for other investors to invest in or purchase these loans. Legal The Company is subject to various claims brought in a litigation or regulatory context. These matters include lawsuits and federal regulatory actions, including but not limited to putative class action lawsuits, derivative lawsuits, and litigation with the FTC. In addition, the Company continues to cooperate in federal and state regulatory examinations, investigations, and actions relating to the Company’s business practices and licensing, and is a party to a number of routine litigation matters arising in the ordinary course of business. The majority of these claims and proceedings relate to or arise from alleged state or federal law and regulatory violations, or are alleged commercial disputes or consumer complaints. The Company accrues for costs related to contingencies when a loss from such claims is probable and the amount of loss can be reasonably estimated. In determining whether a loss from a claim is probable and the loss can be reasonably estimated, the Company reviews and evaluates its litigation and regulatory matters on at least a quarterly basis in light of potentially relevant factual and legal developments. If the Company determines an unfavorable outcome is not probable or the amount of loss cannot be reasonably estimated, the Company does not accrue for a potential litigation loss. In those situations, the Company discloses an estimate or range of the reasonably possible losses, if such estimates can be made. Except as otherwise specifically noted below, at this time, the Company does not believe that it is possible to estimate the reasonably possible losses or a range of reasonably possible losses related to the matters described below. Derivative Lawsuits In May 2016 and August 2016, respectively, two putative shareholder derivative actions were filed ( Avila v. Laplanche, et al. , No. CIV538758 and Dua v. Laplanche, et al. , CGC-16-553731) against certain of the Company’s current and former officers and directors and naming the Company as a nominal defendant. Both actions were voluntarily dismissed without prejudice. On December 14, 2016, another putative shareholder derivative action was filed in the Delaware Court of Chancery ( Steinberg, et al. v. Morris, et al., C.A. No. 12984-CB), against certain of the Company’s current and former officers and directors and naming the Company as a nominal defendant. In addition, on August 18, 2017, another putative shareholder derivative action was filed in the Delaware Court of Chancery ( Fink, et al. v. Laplanche, et al. , C.A. No. 2017-0600). These matters arise from claims that the Board allegedly breached its fiduciary duty by failing to provide adequate oversight over the Company’s practices and procedures, and purport to plead derivative claims under Delaware law. The Court ultimately consolidated the cases, selecting the Steinberg plaintiffs as lead plaintiffs, and designating the Steinberg complaint as the operative complaint (consolidated Delaware matter). In June 2018, the Company and the individual defendants brought a motion to dismiss the consolidated Delaware matter on demand futility grounds or in the alternative to stay the matter. Defendants in the consolidated Delaware matter later consented to the filing of a supplemental consolidated complaint in the case, and the plaintiffs filed that supplemental complaint on January 11, 2019. The Company and individual defendants in the case filed motions to dismiss the supplemental complaint on February 22, 2019. A hearing on these motions was held on July 17, 2019. On October 31, 2019, the Court issued a ruling dismissing the supplemental complaint for failure to plead that a majority of the directors on the Company’s board would have been unable to impartially consider a pre-suit demand. Plaintiffs did not file an appeal of the Court’s ruling by the deadline to file an appeal. The consolidated Delaware matter is therefore concluded. On November 6, 2017, another putative shareholder derivative action was filed in the U.S. District Court for the Northern District of California (Sawyer v. Sanborn, et al., No. 3:17-cv-06447) against certain of the Company’s current and former officers and directors and naming the Company as a nominal defendant. This action was based on allegations similar to those in a consolidated putative securities class action litigation ( In re LendingClub Securities Litigation, No. 16-cv-02627 (N.D. Cal.)) that was successfully settled in 2018. The plaintiffs in the consolidated Delaware matter were permitted to join with the plaintiffs in the Sawyer action for the purposes of settlement. The Court in the Sawyer action concurrently ordered all parties (including the intervening consolidated Delaware matter plaintiffs) to participate in a mediation in May 2018, but that mediation did not result in a settlement. In July 2018, the Company and the individual defendants brought a motion to dismiss the Sawyer matter on the grounds that the action was not filed within the applicable statute of limitations. The Court granted that motion and judgment was entered in favor of the defendants. The Sawyer plaintiff also attempted to intervene in a previously filed derivative action in the U.S. District Court for the Northern District of California ( Stadnicki v. LaPlanche, et al. , No. 3:16-cv-03072). The Company and the individual defendants opposed the intervention, and the original Stadnicki plaintiff moved to voluntarily dismiss the case. The motion to intervene was denied and the motion to voluntarily dismiss the Stadnicki action was granted. Notices of appeal were filed in both the Sawyer and Stadnicki actions. The appeal in the Sawyer matter has been dismissed at the Sawyer plaintiff’s request. The appeal in the Stadnicki matter remains pending and oral argument in that appeal was heard on February 3, 2020. It is not possible for the Company to predict the outcome of the Stadnicki action at this time. FTC Lawsuit In 2016, the Company received a formal request for information from the Federal Trade Commission (FTC). The FTC commenced an investigation concerning certain of the Company’s policies and practices and related legal compliance. On April 25, 2018, the FTC filed a complaint in the Northern District of California ( FTC v. LendingClub Corporation , No. 3:18-cv-02454) alleging causes of action for violations of the FTC Act, including claims of deception in connection with disclosures related to the origination fee associated with loans available through the Company’s platform, and in connection with communications relating to the likelihood of loan approval during the application process, and a claim of unfairness relating to certain unauthorized charges to borrowers’ bank accounts. The FTC’s complaint also alleged a violation of the Gramm-Leach-Bliley Act regarding the Company’s practices in delivering its privacy notice. In June 2018, the Company brought a motion to dismiss the FTC’s complaint, which was heard on September 13, 2018. In an order dated October 3, 2018, the Court denied the motion in part and granted the motion in part, providing the FTC with leave to amend its pleadings. On October 22, 2018, the FTC filed an amended complaint which reasserted the same causes of action from the original complaint. On November 13, 2018, the Company filed an answer to the amended complaint. The FTC subsequently filed a motion seeking to strike certain affirmative defenses pled in the answer and the Company filed an opposition to the motion. On April 29, 2019, the Court issued a ruling denying the FTC’s motion in part and granting it in part and allowing the Company to replead certain of the affirmative defenses that were the subject of the FTC’s motion. The Company filed an amended answer in the case on May 29, 2019. The discovery period in the case is closed. The Court has issued scheduling orders that set various deadlines in the case, including a June 22, 2020 trial commencement date. The Company denies, and will continue to vigorously defend against, the claims asserted in this case. Notwithstanding the Company’s vigorous defense, the Company and the FTC have participated in voluntary settlement conferences and may engage in additional settlement discussions. No assurances can be given as to the timing, outcome or consequences of this matter. Class Action Lawsuits Following Announcement of FTC Litigation In May 2018, following the announcement of the FTC’s litigation against the Company, putative shareholder class action litigation was filed in the U.S. District Court of the Northern District of California ( Veal v. LendingClub Corporation et.al., No. 5:18-cv-02599) against the Company and certain of its current and former officers and directors alleging violations of federal securities laws in connection with the Company’s description of fees and compliance with federal privacy law in securities filings. The Court appointed lead plaintiffs and lead counsel for the litigation in November 2018. On January 7, 2019, the lead plaintiffs filed a consolidated amended class action complaint which asserts the same causes of action as the original complaint and adds additional allegations. On March 8, 2019, the Company and the individual defendants in the case filed motions to dismiss the consolidated amended class action complaint. A hearing on these motions was held on September 26, 2019. On November 4, 2019, the Court issued a written order granting defendants’ motions to dismiss with leave to amend. Plaintiff filed a Second Amended Complaint on December 19, 2019, which modifies and adds certain allegations and drops one of the former officer defendants as a defendant in the case, but otherwise advances the same causes of action. Defendants filed a motion to dismiss the Second Amended Complaint on January 28, 2020. This lawsuit is in the early stages. The Company denies and will vigorously defend against the allegations. No assurances can be given as to the timing, outcome or consequences of this matter. In July 2019, a putative class action lawsuit was filed against the Company in federal court in the State of New York ( Shron v. LendingClub Corp. , 1:19-cv-06718) alleging various claims including fraud, unjust enrichment, breach of contract, and violations of the federal Truth-in-Lending Act and New York General Business Law sections 349 and 350, et seq., based on allegations, among others, that the Company made misleading or inadequate statements or omissions in relation to the total cost and origination fee associated with loans available through the Company’s platform. The plaintiff seeks to represent classes of similarly situated individuals in the lawsuit. The Company has filed a motion to compel arbitration of plaintiff’s claims on an individual basis. The timing of a ruling on that motion is unclear. This matter is in the early stages. The Company denies and will vigorously defend against the allegations. No assurances can be given as to the timing, outcome or consequences of this matter. Derivative Lawsuits Following FTC Litigation In July 2018, a putative shareholder derivative action was filed in the U.S. District Court for the Northern District of California ( Baron v. Sanborn, et al. No. 3:18-cv-04391) against certain of the Company’s current and former officers and directors and naming the Company as a nominal defendant. This action is based on allegations that the individuals breached their fiduciary duties to the Company and violated federal securities laws by, among other things, permitting the actions alleged in the FTC litigation and the description of fees and other practices in the Company’s securities filings. In January 2019, a second putative shareholder derivative action was filed in the U.S. District Court for the Northern District of California ( Cheekatamarla v. Sanborn, et al. , No. 3:19-cv-00563) against certain of the Company’s current officers and directors and naming the Company as a nominal defendant. Like the Baron action, this action is based on allegations that the individuals breached their fiduciary duties to the Company and violated federal securities laws by, among other things, permitting the actions alleged in the FTC litigation and the description of fees and other practices in the Company’s securities filings. Pursuant to a stipulation by the parties in both of these derivative cases, the Court consolidated the two cases and stayed the consolidated action pending further developments in Veal . In September 2019, co-lead counsel for plaintiffs in the consolidated action filed a notice and proposed order to lift the temporary stay and the Court issued an order lifting the stay. Subsequent to this order, the case was reassigned and the new Court issued an order staying the consolidated action pending resolution of the Veal action. No assurances can be given as to the timing, outcome or consequences of this consolidated matter. In August 2019, a putative shareholder derivative action was filed in the Court of Chancery for the State of Delaware ( Fisher v. Sanborn, et al. , Case No. 2019-0631) against certain of the Company’s current and former officers and directors and naming the Company as a nominal defendant. This lawsuit advances allegations similar to those in the consolidated Baron/Cheekatamarla actions and the Veal action discussed above and accuses the individual defendants of breaching their fiduciary duties by failing to adequately monitor the Company and prevent it from engaging in the purported regulatory violations alleged by the FTC and by causing the Company to make allegedly false and misleading public statements (as alleged in the Veal action). The lawsuit also alleges that certain of the individual defendants breached their fiduciary duties by selling Company shares while in possession of material, non-public information. On October 11, 2019, the Company and the individual defendants filed a motion to dismiss the complaint. In November 2019, rather than opposing defendants motion to dismiss, the plaintiff filed an amended complaint. That same month, the Company and the individual defendants named in the amended complaint filed a motion to dismiss that amended complaint. On January 17, 2020, rather than opposing defendants motion to dismiss, the plaintiff filed a second amended complaint. On January 24, 2020, defendants filed a motion to strike the second amended complaint as improper. No assurances can be given as to the timing, outcome or consequences of this matter. Regulatory Investigation by the State of Massachusetts In June 2018, the Company received a civil investigative demand from the office of the Attorney General of the State of Massachusetts. The investigation relates to the advertisement, provision and servicing of personal loans to Massachusetts’ consumers facilitated by the Company. The Company is cooperating with the investigation. The Company and the Attorney General’s Office have recently communicated regarding questions and concerns the Attorney General’s Office has regarding the Company’s compliance with the Massachusetts Small Loan Law and the Small Loan Rate Order promulgated under it. The Attorney General’s Office has also sent additional information requests to the Company. The Company has finalized an Assurance of Discontinuance with the Attorney General’s Office to resolve the investigation, the terms of which are not material to the Company’s financial position or results of operations. In December 2019, the Massachusetts Division of Banks raised concerns pertaining to the Company’s compliance with the Massachusetts Small Loan Law similar to those the Massachusetts Attorney General’s Office raised during its investigation of the Company. No assurances can be given as to the timing, outcome or consequences of this matter; however, it could result in claims or actions against the Company, including litigation, regulatory enforcement actions, injunctions, monetary damages, fines or penalties, impact our licenses in Massachusetts, or require us to change our business practices or expend operational resources, all of which could result in a material loss or otherwise harm our business. Regulatory Examinations and Actions Relating to the Company’s Business Practices and Licensing The Company has been subject to periodic inquiries and enforcement actions brought by federal and state regulatory agencies relating to the Company’s business practices, the required licenses to operate its business, and its manner of operating in accordance with the requirements of its licenses. In the past, the Company has successfully resolved inquiries in a manner that was not material to its results of financial operations in any period and that did not materially limit the Company’s ability to conduct its business. The Company has had discussions with the Colorado Department of Law (CDL) concerning the licenses required for the Company’s servicing operations and the structure of its offerings in the State of Colorado. The Company has also had discussions with the CDL about entering into a terminable agreement with the CDL to, among other things: (i) toll the statutes of limitations on any action the CDL might bring against the Company based on the rates and charges on loans the Company facilitates and (ii) refrain from facilitating certain loans to borrowers located in Colorado available for investment by certain investors. No assurances can be given as to the timing, outcome or consequences of this matter. The Company is routinely subject to examination for compliance with applicable laws and regulations in the states in which it is licensed. As of the date of this Report, the Company is subject to examination by the New York Department of Financial Services (NYDFS). The Company periodically has discussions with various regulatory agencies regarding its business model and has recently engaged in similar discussions with the NYDFS. During the course of such discussions, which remain ongoing, the Company decided to voluntarily comply with certain rules and regulations of the NYDFS. No assurances can be given as to the timing, outcome or consequences of this matter. Putative Class Actions In September 2018, a lawsuit was filed against the Company in the State of New York ( Accardo v. Lending Club, et al. , 2:18-cv-05030-JS-AKT) asserting an individual claim under the federal Fair Credit Reporting Act against the Company. In early 2019, the plaintiff filed a motion for leave to amend his complaint in the case to assert a putative class claim under the Fair Credit Reporting Act. The plaintiff’s proposed amended complaint contends that LendingClub failed to conduct a reasonable investigation into plaintiff’s identity theft dispute and plaintiff seeks to represent a class of similarly situated individuals. The Company filed an opposition to plaintiff’s motion for leave to amend and also filed a motion to compel arbitration of plaintiff’s claim against the Company on an individual basis. The Court has denied the Company’s motion to compel arbitration and has ordered a trial on whether an arbitration agreement exists between the Company and Plaintiff. The Court also denied without prejudice Plaintiff’s motion for leave to amend. The Company has reached a tentative settlement with the plaintiff to resolve this matter, the terms of which are not material to the Company’s financial position or results of operations, and the parties are working to finalize a written settlement agreement. The Company denies and will vigorously defend against the allegations in the event the litigation continues. No assurances can be given as to the timing, outcome or consequences of this matter. In February 2020, a putative class action lawsuit was filed against the Company in the U.S District Court for the Northern District of California ( Erceg v. LendingClub Corporation , No. 3:20-cv-01153). The lawsuit alleges violations of California and Massachusetts law based on allegations that LendingClub recorded a call with plaintiff without notifying him that it would be recorded. Plaintiff seeks to represent a purported class of similarly situated individuals who had phone calls recorded by LendingClub without their knowledge and consent. LendingClub has not yet filed a formal response to plaintiff's complaint. No assurances can be given as to the timing, outcome or consequences of this matter. California Private Attorneys General Lawsuit In September 2018, a putative action under the California Private Attorney General Act was brought against the Company in the California Superior Court ( Brott v. LendingClub Corporation, et al. , CGC-18-570047) alleging violations of the California Labor Code. The complaint by a former employee alleges that the Company improperly failed to pay certain hourly employees for all wages owed, pay the correct rate of pay including overtime, and provide accurate wage statements. The lawsuit alleges that the plaintiff and aggrieved employees are entitled to recover civil penalties under the California Labor Code. On January 11, 2019, the Company filed a petition to compel arbitration of the plaintiff’s claims and stay the litigation pending a ruling on the motion and arbitration of the matter. Pursuant to the parties’ stipulation, in March 2019, the Court issued an order staying the lawsuit pending the parties’ participation in a mediation in September 2019. The parties have reached a resolution of this matter, the terms of which are not material to the Company’s financial position or results of operations. The resolution will require court approval. The parties have finalized a written settlement agreement and will seek the Court’s approval of the negotiated resolution. Certain Financial Considerations Relating to Litigation and Investigations With respect to the matters discussed above, the Company had $16.0 million and $12.8 million in accrued contingent liabilities as of December 31, 2019 and 2018 , respectively. The increase in accrued contingent liabilities as of December 31, 2019 compared to December 31, 2018 was primarily related to litigation and regulatory matters of $3.3 million during 2019 , which is included in “Other general and administrative” expense on the Company’s Consolidated Statements of Operations . Class action and regulatory litigation expense related to significant governmental and regulatory investigations following the internal board review described more fully in “ Management’s Discussion and Analysis of Financial Condition and Results of Operations – Board Review ” contained in Part II, Item 7 of the Company’s Annual Report on Form 10-K for the year ended December 31, 2016, was $35.5 million and $77.3 million for the years ended December 31, 2018 and 2017 , respectively. This expense is included in “Class action and regulatory litigation expense” on the Company’s Consolidated Statements of Operations . The Company had no class action and regulatory litigation expense for the year ended December 31, 2019 . In addition to the foregoing, the Company is subject to, and may continue to be subject to, legal proceedings and regulatory actions in the ordinary course of business. No assurance can be given as to the timing, outcome or consequences of any of these matters.

Segment Reporting

Segment Reporting [Abstract]
Segment Reporting	Segment Reporting The Company defines operating segments to be components of the Company for which discrete financial information is evaluated regularly by the Company’s executive management committee as chief operating decision maker (CODM). For purposes of allocating resources and evaluating financial performance, the Company’s CODM reviews financial information by loan product types of personal, education and patient finance, and auto. These product types are individually reviewed as operating segments but are aggregated to represent one reportable segment because the education and patient finance and auto loan product types are immaterial both individually and in the aggregate. In the second quarter of 2019, the Company sold certain assets relating to its small business operating segment and announced that it will connect applicants looking for a small business loan with strategic partners and earn referral fees, instead of facilitating these loans on its platform. All of the Company’s revenue is generated in the United States. No individual borrower or investor accounted for 10% or more of consolidated net revenue for any of the periods presented.

Related Party Transactions [Abstract]
Related Party Transactions	Related Party Transactions Related party transactions must be reviewed and approved by the Audit Committee of the Company’s board of directors when not conducted in the ordinary course of business subject to the standard terms of the Company’s lending marketplace or certificate investment program. Any material amendment or modification to an existing related party transaction is also subject to the review and approval of the Audit Committee. Related party transactions may include any transaction between entities under common control or with a related person that has occurred since the beginning of the Company’s latest fiscal year or is currently proposed. The Company has defined related persons as members of the board of directors, executive officers, principal owners of the Company’s outstanding stock and any immediate family members of each such related person, as well as any other person or entity with significant influence over the Company’s management or operations. Several of the Company’s executive officers and directors (including immediate family members) have made deposits and withdrawals to their investor accounts and purchased loans or interests therein. The Company believes all such transactions by related persons were made in the ordinary course of business and were transacted on terms and conditions that were not more favorable than those obtained by similarly situated third-party investors. As of December 31, 2019 , the Company had a $7.7 million investment and an approximate 23% ownership interest in an Investment Fund, a private fund that participates in a family of funds with other unrelated third parties. This family of funds purchases whole loans and interests in loans from the Company, as well as other assets from third parties unrelated to the Company. The Company’s investment in the Investment Fund is recorded in “Other assets” on the Company’s Consolidated Balance Sheets . During 2019 , 2018 and 2017, the family of funds purchased $77 thousand , $6.6 million and $53.3 million , respectively, of whole loans. During 2019 , 2018 and 2017, the Company earned $93 thousand , $262 thousand and $734 thousand in investor fees from this family of funds, and paid interest of $778 thousand , $2.9 million and $7.4 million on the funds’ interests in whole loans, respectively. The Company believes that the investor fees charged were on terms and conditions that were not more favorable than those obtained by other third-party investors.

Subsequent Events [Abstract]
Subsequent Events	Subsequent Events The Company has evaluated the impact of events that have occurred subsequent to December 31, 2019 , through the date the consolidated financial statements were filed with the SEC. Based on this evaluation, other than as recorded or disclosed within these consolidated financial statements and related notes, including as disclosed below, the Company has determined no additional subsequent events were required to be recognized or disclosed. On February 18, 2020, the Company and Radius Bancorp, Inc. (Radius) entered into an Agreement and Plan of Merger, by and among the Company, a wholly owned-subsidiary of the Company, and Radius, pursuant to which the Company will acquire Radius and thereby acquire its wholly-owned subsidiary, Radius Bank (the Merger), in a cash and stock transaction valued at $185 million (of which $138.75 million is in cash and $46.25 million is in stock), plus certain purchase price and expense adjustments of up to $22 million . The closing of the Merger is subject to regulatory approval and other customary closing conditions, which the Company anticipates can be completed within 15 months , as well as customary transaction costs. The Merger will be accounted for as a business combination. The purchase price will be allocated to the assets acquired and liabilities assumed based on their fair values at the acquisition date. In order to facilitate compliance with federal banking regulations by the Company’s largest stockholder, Shanda Asset Management Holdings Limited and its affiliates (Shanda), on February 18, 2020, the Company entered into a Share Exchange Agreement pursuant to which Shanda will exchange all shares of the Company’s common stock held by Shanda for newly issued non-voting convertible preferred stock, series A (the Exchange). In connection with the Exchange, the Company will provide Shanda registration rights and a one-time cash payment of approximately $50 million . To deter future ownership positions in the Company’s securities in excess of thresholds set forth by the Federal Reserve under the Bank Holding Company Act, the Company adopted a Temporary Bank Charter Protection Agreement (the Charter Protection Agreement) which provides for the dilution of any person or group of persons that acquires: (i) 25% or more equity interest in the Company, or (ii) 7.5% or more of any class of the Company’s voting securities, which threshold shall automatically increase to 10% in connection with the closing of the Exchange. The Charter Protection Agreement is effective as of February 18, 2020, and will automatically expire on the earlier of the closing of the Merger or 18 months

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2019
Accounting Policies [Abstract]
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents include the Company’s unrestricted deposits with investment-grade financial institutions, institutional money market funds, certificates of deposit, and commercial paper. The Company considers all highly liquid investments with stated maturity dates of three months or less from the date of purchase to be cash equivalents.
Restricted Cash	Restricted Cash Restricted cash consists primarily of bank deposits and money market funds that are: (i) pledged as security for transactions processed on or related to LendingClub’s platform or activities by certain investors; and (ii) received from the borrower and applied to the loan, but not yet distributed to the investor’s internal platform account or sent to their external account. Investor cash balances (excluding transactions-in-process) are held in segregated bank or custodial accounts and are not commingled with the Company’s monies or held on the Company’s Consolidated Balance Sheets .
Securities Available for Sale	Securities Available for Sale Debt securities that the Company might not hold until maturity are classified as securities available for sale. In structured program transactions that meet the applicable criteria to be accounted for as a sale, the Company retains certain asset-backed securities including subordinated residual interests and CLUB Certificates, which are classified as securities available for sale. Securities available for sale are recorded at fair value and unrealized gains and losses are reported, net of taxes, in “Accumulated other comprehensive income (loss)” included in Equity in the Company’s Consolidated Balance Sheets unless management determines that a security is other-than-temporarily impaired (OTTI). Realized gains and losses from sales of securities available for sale are included in “Net fair value adjustments” in the Company’s Consolidated Statements of Operations . Management evaluates whether debt securities available for sale with unrealized losses are OTTI on a quarterly basis. If the Company intends to sell the security, or if it is more likely than not that it will be required to sell the security before recovery, an OTTI is recognized in earnings equal to the entire difference between the amortized cost basis and fair value of the debt security. However, even if the Company does not expect to sell a debt security it must evaluate the expected cash flows to be received and determine if a credit loss exists. In the event of a credit loss, only the amount of impairment associated with the credit loss is recognized in earnings and amounts related to factors other than credit losses are recorded in other comprehensive income. Impairment charges are recorded in “Net fair value adjustments” in the Company’s Consolidated Statements of Operations .
Loans Held for Investment by the Company	Loans Held for Investment by the Company and Loans Held for Sale by the Company The Company has elected the fair value option for loans held for investment by the Company and loans held for sale by the Company. Changes in the fair value of loans held by the Company are recorded in “Net fair value adjustments” in the Consolidated Statements of Operations in the period of the fair value changes. The Company places loans held by the Company on non-accrual status at 90 days past due. Accrued interest income on loans held by the Company is calculated based on the contractual interest rate of the loan held by the Company and recorded as interest income as earned. When a loan held by the Company is placed on non-accrual status, the Company stops accruing interest and reverses all accrued but unpaid interest as of such date. The Company charges-off loans held by the Company no later than 120 days past due.
Loans Held for Sale by the Company	Loans Held for Investment by the Company and Loans Held for Sale by the Company The Company has elected the fair value option for loans held for investment by the Company and loans held for sale by the Company. Changes in the fair value of loans held by the Company are recorded in “Net fair value adjustments” in the Consolidated Statements of Operations in the period of the fair value changes. The Company places loans held by the Company on non-accrual status at 90 days past due. Accrued interest income on loans held by the Company is calculated based on the contractual interest rate of the loan held by the Company and recorded as interest income as earned. When a loan held by the Company is placed on non-accrual status, the Company stops accruing interest and reverses all accrued but unpaid interest as of such date. The Company charges-off loans held by the Company no later than 120 days past due.
Loans Held for Investment and Related Notes and Certificates	Loans Held for Investment and Related Notes and Certificates The Company has elected the fair value option for loans held for investment and related notes and certificates. Due to the payment dependent feature of the notes and certificates, changes in the fair value of the notes and certificates are offset by changes in the fair values of related loans, resulting in no net effect on the Company’s earnings. The Company places loans held for investment on non-accrual status at 90 days past due. Interest receivable on loans held for investment and accrued interest payable on notes and certificates are reduced when the corresponding loan held for investment is placed on non-accrual status due to the payment dependent nature of the loans held for investment and related notes and certificates. The Company charges-off loans held for investment and related notes and certificates no later than 120 days past due.
Servicing Assets and Liabilities	Servicing Assets The Company records servicing assets at their estimated fair values when it sells loans or when the Company assumes or acquires a servicing obligation whereby the underlying loans are not included in its financial statements. The gain or loss on a loan sale is recorded separately in “Gain on sales of loans” in the Company’s Consolidated Statements of Operations while the component of the gain or loss that is based on the degree to which the contractual servicing fee is above or below an estimated market servicing rate is recorded as a servicing asset. Servicing assets are reported in “Other assets” on the Company’s Consolidated Balance Sheets . Changes in the fair value of servicing assets are reported in “Investor fees” in the Company’s Consolidated Statements of Operations in the period in which the changes occur.
Fair Value of Assets and Liabilities	Fair Value of Assets and Liabilities Fair value is the price that would be received to sell a financial asset or paid to transfer a financial liability in an orderly transaction between market participants at the measurement date (an exit price). The Company uses fair value measurements in its fair value disclosures and to record securities available for sale, loans held for investment and loans held for sale, notes and certificates, and servicing assets and liabilities at fair value on a recurring basis. The fair value hierarchy includes a three-level classification, which is based on whether the inputs to the valuation methodology used for measurement are observable: Level 1 — Quoted market prices in active markets for identical assets or liabilities. Level 2 — Inputs other than quoted prices included in Level 1 that are observable for the asset or liability either directly or indirectly. Level 3 — Unobservable inputs. When developing fair value measurements, the Company maximizes the use of observable inputs and minimizes the use of unobservable inputs. However, for certain instruments the Company must utilize unobservable inputs in determining fair value due to the lack of observable inputs in the market, which requires greater judgment in measuring fair value. In instances where there is limited or no observable market data, fair value measurements for assets and liabilities are based primarily upon the Company’s own estimates, and the measurements reflect information and assumptions that management believes a market participant would use in pricing the asset or liability. Loans held for investment, loans held for sale and related notes, certificates and secured borrowings, are measured at estimated fair value using a discounted cash flow model. The fair valuation methodology considers projected prepayments, underwriting changes and the historical actual defaults, losses and recoveries on the Company’s loans to project future losses and net cash flows on loans. Net cash flows on loans are discounted using an estimate of market rates of return. Loan servicing assets are measured at estimated fair value using a discounted cash flow model. The cash flows in the valuation model represent the difference between the contractual servicing fees charged to investors and an estimated market servicing rate. Since contractual servicing fees are generally based on the monthly unpaid principal balance of the underlying loans, the expected cash flows in the model incorporate estimates of net expected losses and prepayments. The Company uses prices obtained from third-party pricing services to measure the fair value of securities available for sale when available. The Company compares the prices obtained from its primary independent pricing service to the prices obtained from the additional independent pricing services to determine if the price obtained from the primary independent pricing service is reasonable. When third-party pricing services are not available for a security, such as subordinated residual certificates and CLUB Certificates, the Company measures the fair value of these securities using a discounted cash flow model incorporating inputs consistent with loans held for investment, loans held for sale and related notes, certificates, secured borrowings, and payable to securitization note and certificate holders.
Property, Equipment and Software, Net	Property, Equipment and Software, net Property, equipment and software are carried at cost less accumulated depreciation and amortization. The Company uses the straight-line method of depreciation and amortization. Estimated useful lives range from three years to five years for furniture and fixtures, computer equipment, and software. Leasehold improvements are amortized over the shorter of the lease term or the estimated useful life. Internally developed software is capitalized when preliminary development efforts are successfully completed and it is probable that the project will be completed, and the software will be used as intended. Capitalized costs consist of salaries and compensation costs for employees, fees paid to third-party consultants who are directly involved in development efforts, and costs incurred for upgrades and enhancements to add functionality of the software. Other costs are expensed as incurred. The Company evaluates impairments of its property, equipment and software whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. If the asset is not recoverable, measurement of an impairment loss is based on the fair value of the asset. When an impairment loss is recognized, the carrying amount of the asset is reduced to its estimated fair value.
Goodwill and Intangible Assets	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 more frequently 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 an operating segment or one level below an operating segment 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 either an income approach (discounted cash flow model) or the income approach corroborated by a market approach. Goodwill impairment loss is measured as the amount by which the carrying amount of a reporting unit exceeds its fair value. 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 and revenue growth, projected operating expenses and Contribution Margin, direct and allocated general and administrative and technology expenses, 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 involve the use of estimates and judgments, particularly related to future cash flows, which are inherently uncertain. There can be no assurances that 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. Goodwill impairment loss is measured as the amount by which the carrying amount of a reporting unit exceeds its fair value. See “ Note 11. Intangible Assets and Goodwill ” for additional information. 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 indefinite-lived intangible assets.
Loss Contingencies	Loss Contingencies Loss contingencies, including claims and legal actions arising in the ordinary course of business, are recorded as liabilities in “Accrued expenses and other liabilities” in the Company’s Consolidated Balance Sheets . Associated legal expense is recorded in “Other general and administrative” expense or in “Class action and regulatory litigation expense” for the losses associated with the securities class action lawsuits, as described in “ Note 19. Commitments and Contingencies , ” in the Company’s Consolidated Statements of Operations . Such liabilities and associated expenses are recorded when the likelihood of loss is probable and an amount or range of loss can be reasonably estimated. The Company will also disclose a range of exposure to incremental loss when such amounts are reasonably possible and can be estimated. In estimating the Company’s exposure to loss contingencies, if an amount within the estimated range of loss is the best estimate, that amount will be accrued. However, if there is no amount within the estimated range of loss that is the best estimate, the Company will accrue the minimum amount within the range, and disclose the amount up to the high end of the range as an exposure to incremental loss, if such amount is considered reasonably possible. Such estimates are based on the best information available at the time. As additional information becomes available, the Company reassesses the potential liability and records an adjustment to its estimate in the period in which the adjustment is probable and an amount or range can be reasonably estimated. The determination of an expected contingent liability and associated litigation expense requires the Company to make assumptions related to the outcome of these matters. Due to the inherent uncertainties of loss contingencies, the Company’s estimates may be different than the actual outcomes. Legal fees, including legal fees associated with loss contingencies, are recognized as incurred and included in “Other general and administrative” expense in the Company’s Consolidated Statements of Operations .
Insurance Recoveries	Insurance Recoveries Insurance recoveries of all or a portion of incurred losses are recognized when realization of the claim for recovery is probable. Any insurance recoveries in excess of losses incurred are accounted for as a gain contingency. Insurance recoveries are recorded in “Other assets” in the Company’s Consolidated Balance Sheets . Insurance recoveries associated with the reimbursement of legal expenses arising from loss contingencies and legal fees are recorded as a contra-expense in “Other general and administrative” expense or, if such recoveries are associated with the securities class action lawsuits, as a contra-expense in “Class action and regulatory litigation expense” in the Company’s Consolidated Statements of Operations .
Revenue Recognition	Revenue Recognition Transaction Fees : The Company has a single performance obligation to provide customers access to the Company’s platform. Transaction fees are considered revenue from contracts with customers, including issuing banks and education and patient service providers. The Company recognizes transaction fee revenue each time a loan is facilitated by the Company, who provides loan application processing and loan facilitation services, resulting in a loan issued by the customers. Transaction fees are based on the initial principal amount of the loans facilitated by the Company and paid by the issuing banks and education and patient service providers each time a loan is issued by the issuing banks. Transaction fees to which the Company expects to be entitled are variable consideration because loan volume originated over the contractual term is not known at the contract’s inception. The transaction fee is determined each time a loan is issued based on that loan’s initial principal amount. The Company pays WebBank a loan trailing fee to give WebBank an ongoing financial interest in the performance of the loans it originates and sells to the Company. The Loan Trailing Fee is paid over time based on the amount and timing of principal and interest payments made by borrowers of the underlying loans. The Loan Trailing Fee is consideration payable to WebBank and the loan trailing fee liability is recorded at fair value. Additionally, the Company assumes the issuing bank’s obligation under Utah law to refund the pro-rated amount of the transaction fee in excess of 5% in the event the borrower prepays the loan in full before maturity. Both the loan trailing fees and transaction fee refunds are recorded as a reduction of transaction fee revenue in the Company’s Consolidated Statements of Operations and are included in “Accrued expenses and other liabilities” on the Company’s Consolidated Balance Sheets. Other Revenue : Other revenue primarily consists of referral fee revenue and sublease revenue from our sublet office space in San Francisco, California. The Company is entitled to receive referral fees from third-party companies when customers referred by the Company consider or purchase products or services from such third-party companies. Referral contracts contain a single performance obligation. The Company recognizes referral fees for each distinct instance when the criteria for receiving the referral fee has been satisfied. Sublease revenue is recognized on a straight-line basis over the term of the lease.
Stock-based Compensation	Stock-based Compensation Stock-based compensation includes expense associated with restricted stock units (RSUs) and performance-based restricted stock units (PBRSUs), stock options, and the Company’s employee stock purchase plan (ESPP), as well as expense associated with stock issued related to acquisitions. Stock-based compensation expense is based on the grant date fair value of the award. The cost is generally recognized over the vesting period on a straight-line basis. Forfeitures are recognized as incurred.
Income Taxes	Income Taxes The Company accounts for income taxes under the asset and liability method. Under this method, deferred tax assets and liabilities are determined on the basis of the differences between the financial statement and tax bases of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date. The Company recognizes deferred tax assets to the extent that it believes these assets are more likely than not to be realized. In making such a determination, the Company considers the available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies, and results of recent operations. Valuation allowances are established when necessary to reduce deferred tax assets to the amounts that are more likely than not expected to be realized. If the Company determines that it is able to realize its deferred tax assets in the future in excess of the net recorded amount, the Company decreases the deferred tax asset valuation allowance, which reduces the provision for income taxes. Uncertain tax positions are recognized only when we believe it is more likely than not that the tax position will be upheld on examination by the taxing authorities based on the merits of the position. The Company recognizes interest and penalties, if any, related to uncertain tax positions in “Income tax expense (benefit)” in the Consolidated Statements of Operations.
Net Income (Loss) Per Share	Net Income (Loss) Per Share Basic net income (loss) per share (Basic EPS) attributable to common stockholders is computed by dividing net income (loss) attributable to LendingClub by the weighted-average number of shares of common stock outstanding during the period. Diluted net income (loss) per share (Diluted EPS) is computed by dividing net income (loss) attributable to LendingClub by the weighted-average number of shares of common stock outstanding during the period, adjusted for the effects of dilutive shares of common stock, which include incremental shares issued for RSUs, PBRSUs, and stock options. PBRSUs are included in dilutive shares to the extent the pre-established targets have been or are estimated to be satisfied as of the reporting date. The dilutive potential common shares are computed using the treasury stock method. The effects of outstanding RSUs, PBRSUs, and stock options are excluded from the computation of Diluted EPS in periods in which the effect would be antidilutive.
Consolidation of Variable Interest Entities	Consolidation of Variable Interest Entities A variable interest entity (VIE) is a legal entity that has either a total equity investment that is insufficient to finance its activities without additional subordinated financial support or whose equity investors lack the characteristics of a controlling financial interest. The Company’s variable interest arises from contractual, ownership or other monetary interests in the entity, which change with fluctuations in the fair value of the entity’s net assets. A VIE is consolidated by its primary beneficiary, the party that has both the power to direct the activities that most significantly impact the VIE’s economic performance, and the obligation to absorb losses or the right to receive benefits of the VIE that could potentially be significant to the VIE. The Company consolidates a VIE when it is deemed to be the primary beneficiary. The Company assesses whether or not it is the primary beneficiary of a VIE on an ongoing basis.
Transfers of Financial Assets	Transfers of Financial Assets The Company accounts for transfers of financial assets as sales when it has surrendered control over the transferred assets. Control is generally considered to have been surrendered when the transferred assets have been legally isolated from the Company, the transferee has the right to pledge or exchange the assets without any significant constraints, and the Company has not entered into a repurchase agreement, does not hold unconditional call options and has not written put options on the transferred assets. In assessing whether control has been surrendered, the Company considers whether the transferee would be a consolidated affiliate and the impact of all arrangements or agreements made contemporaneously with, or in contemplation of the transfer, even if they were not entered into at the time of transfer. The Company measures gain or loss on sale of financial assets as the net proceeds received on the sale less the carrying amount of the loans sold. The net proceeds of the sale represent the fair value of any assets obtained or liabilities incurred as part of the transaction, including, but not limited to servicing assets, retained securities, and recourse obligations. 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 Consolidated Balance Sheets 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 assets.
New Accounting Standards	Adoption of New Accounting Standards The Company adopted the following accounting standards during the year ended December 31, 2019 : Accounting Standards Update (ASU) 2016-02, Leases (Topic 842), requires lessees to record on their balance sheets a lease liability for the obligation to make lease payments and a right-of-use (ROU) asset for the right to use the underlying asset for the lease term. The Company adopted Topic 842 as of January 1, 2019 and has elected not to restate comparative periods presented in the consolidated financial statements. The Company has chosen not to elect the practical expedients permitted under the transition guidance within the new standard, which among other things, permits entities to carry forward their historical lease identification. The Company has made an accounting policy election to not recognize lease liabilities and ROU assets for short-term leases, which are leases with initial terms of 12 months or less and for which there is not a purchase option that is reasonably certain to be exercised. All leases within the Company’s portfolio are classified as operating leases. Adoption of Topic 842 had an impact on the Company’s Consolidated Balance Sheets but did not have an impact on the Company’s Consolidated Statements of Operations or Consolidated Statements of Cash Flows . The most significant impact was the recognition of ROU assets and lease liabilities of $95.2 million and $110.1 million at the time of adoption, respectively, with no cumulative effect in retained earnings. The difference between the ROU assets and lease liabilities is the unamortized balance of deferred rent, which prior to January 1, 2019, was included as a separate liability within Accrued expenses and other liabilities. The operating lease expenses are included in Other general and administrative expense and sublease income is recorded in Other revenue in the Company’s Consolidated Statements of Operations . The Company included the disclosures required by ASU 2016-02 in “ Note 18. Leases .” In July 2019, the Financial Accounting Standards Board (FASB) issued ASU 2019-07, Codification Updates to SEC Sections . The ASU clarifies and/or improves the disclosure and presentation requirements of a variety of codification topics by aligning them with the Securities and Exchange Commission’s regulations, thereby eliminating redundancies and making the codification easier to apply. This ASU became effective upon issuance and did not have a significant impact on the Company’s consolidated financial statements and related disclosures. New Accounting Standards Not Yet Adopted In June 2016, the FASB amended guidance related to impairment of financial instruments as part of ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments , which became effective on January 1, 2020. For loans accounted for at amortized cost, the guidance replaces the incurred loss impairment methodology with an expected credit loss model for which a company recognizes an allowance based on the estimate of expected credit loss. Because the Company has elected the fair value option for loans and loans accounted for at fair value through net income are outside the scope of Topic 326, the Company expects no impact on its loan portfolios upon adoption. For accrued interest receivable related to such loans, the Company has made an accounting policy election not to measure an allowance for credit losses on accrued interest receivable as the Company writes off uncollectible accrued interest receivable in a timely manner. Uncollectible accrued interest receivable amounts are written off to interest income. For debt securities available for sale, Topic 326 requires recognition of expected credit losses by recognizing an allowance for credit losses when the fair value of the security is below amortized cost and the recognition of this allowance is limited to the difference between the security’s amortized cost basis and fair value. The standard eliminates the existing guidance for purchased credit impaired assets but requires an allowance for purchased financial assets with more than insignificant deterioration since origination. The measurement guidance for purchased financial assets with credit deterioration also applies to beneficial interests classified as available for sale where there is a significant difference between contractual and expected cash flows at the date of recognition. Upon adoption, the amendments in Topic 326 will be recognized through a cumulative-effect adjustment to retained earnings, except for debt securities with prior other-than-temporary impairment whereby Topic 326 is applied prospectively. The Company made substantial progress in line with the established project plan and determined there was not a transition adjustment upon adoption of the standard on January 1, 2020. The targeted amendments to the debt securities available for sale impairment model do not have a material impact on the Company’s financial position, results of operations, cash flows, and disclosures for transition securities; the Company is still evaluating the impact for new securities acquired on and after January 1, 2020. In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement , which modifies the disclosure requirements on fair value measurements by removing, modifying, or adding certain disclosures. The ASU eliminates such disclosures as the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy and valuation processes for Level 3 fair value measurements. The ASU adds new disclosure requirements for Level 3 measurements. The new guidance became effective on January 1, 2020. The Company is finalizing the impact this ASU will have on its disclosures and does not expect such adoption to have a material impact. In August 2018, the FASB issued ASU 2018-15, Intangibles – Goodwill and Other – Internal-Use Software – (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract , which requires a customer in a hosting arrangement that is a service contract to follow the internal-use software guidance in ASC 350-40 to determine which implementation costs to capitalize as assets or expense as incurred. The standard became effective on January 1, 2020 and the Company adopted the standard using the prospective approach. The Company has reviewed existing cloud computing arrangements and determined which ones are service contracts. Implementation costs that are not from internal developers related to service contracts that satisfy the criteria for capitalization under ASC 350-40 will be presented with “Other assets” on the Company’s Consolidated Balance Sheets , amortization expense will be presented in the same line on the income statement as the fees for the associated hosted service on the Company’s Consolidated Statements of Operations , and the cash flows will be presented consistent with the presentation of cash flows for the fees related to the hosted service, generally as cash flows from operations, on the Company’s Consolidated Statements of Cash Flows . The Company does not expect such adoption will have a material impact on its financial position, results of operations or cash flows. In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes , which is part of the FASB’s initiative to reduce complexity in accounting standards. The proposed ASU eliminates certain exceptions to the general principles of ASC 740, Income Taxes , and simplifies income tax accounting in several areas. The standard is effective on January 1, 2021 with early adoption permitted. The Company plans to adopt early for the interim period ending March 31, 2020. The Company is evaluating the impact this ASU will have on its financial position, results of operations, cash flows, and disclosures, but does not expect such adoption to have a material impact.
