	1. Basis of Presentation
	The condensed consolidated financial statements as of June 30, 2014 and December 31, 2013 and for the three and six months ended June 30, 2014 and 2013, respectively have been prepared by LendingClub Corporation in conformity with U.S. generally accepted accounting principles (“GAAP”) for interim financial information. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements.
	The Company did not have any items of other comprehensive income (loss) during any of the periods presented in the condensed consolidated financial statements as of and for the three and six months ended June 30, 2014 and 2013, respectively.
	In the opinion of management, all necessary adjustments (including only those of a normal recurring nature) have been made for a fair presentation of the financial position, results of operations, and cash flows for the interim periods presented. The results of operations for the interim periods are not necessarily indicative of the results for the full fiscal year. The unaudited interim condensed consolidated financial statements should be read in conjunction with the audited financial statements and notes thereto for the year ended December 31, 2013.
	The preparation of our condensed consolidated financial statements and related disclosures in conformity with GAAP requires management to make judgments, assumptions and estimates that affect the amounts reported in our condensed consolidated financial statements and accompanying notes. We base our estimates on historical experience and on various other factors we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of certain assets and liabilities. These judgments, 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 presentation. These reclassifications had no impact on previously reported results of consolidated operations.
	On April 15, 2014, the Board of Directors approved a 2 for 1 equity stock split in which each outstanding share of each series or class of equity capital stock was split into two outstanding shares of such series or class of equity capital stock. All share and per share data has been adjusted to reflect this stock split.
	On April 17, 2014, we acquired all the outstanding limited liability company interests of Springstone. As such, our condensed consolidated financial statements include Springstone’s results of operations and financial position from this date (see Note 7 – Springstone Acquisition).

	2. Summary of Significant Accounting Policies
	Our significant accounting policies are included in Note 2 – Summary of Significant Accounting Policies in our Annual Report on Form 10-K for the year ended December 31, 2013. There have been no changes to these accounting policies during the first six months of 2014 except for the application of the acquisition method in accounting for a business combination, the accounting for intangible assets, including goodwill and the accounting for servicing assets and liabilities, as described below.
	Goodwill and Intangible Assets
	Goodwill represents the fair value of acquired businesses in excess of the fair value of the individually identified net assets acquired. Goodwill is not amortized but is tested for impairment annually or whenever indications of impairment exist. Our annual impairment testing date is April 1. We can elect to qualitatively assess goodwill for impairment if it is more likely than not that the fair value of a reporting unit (defined as business for which financial information is available and reviewed regularly by management) exceeds its carrying value. A qualitative assessment may consider macroeconomic and other industry-specific factors, such as trends in short-term and long-term interest rates and the ability to access capital, or company specific factors such as market capitalization in excess of net assets, trends in revenue generating activities and merger or acquisition activity.
	If we elect to bypass qualitatively assessing goodwill, or it is not more likely than not that the fair value of a reporting unit exceeds its carrying value, management will estimate the fair values of our reporting units and compare them to their carrying values. The estimated fair values of the reporting units will generally be established using an income approach based on a discounted cash flow model or a market approach which compares each reporting unit to comparable companies in their respective industries.
	Intangible assets are amortized over their useful lives in a manner that best reflects their economic benefit. Intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. We do not have any indefinite-lived intangible assets.
	Servicing Asset/Liability
	For whole loans sold to unrelated third party purchasers with servicing retained, we use a discounted cash flow model to estimate the fair value of the loan servicing asset or liability which considers the contractual servicing fee revenue we earn on the sold loans, an estimated market servicing rate to service such loans, the current principal balances of the loans and projected servicing revenues over the remaining terms of the loans. We record servicing assets and liabilities at their estimated fair values at the time the loans are sold. Changes in the estimated fair value of servicing assets and liabilities are reported in “Servicing Fees” in the period in which the change occurs. Servicing assets and liabilities are recorded in “Other Assets” and “Accrued Expenses and Other Liabilities”, respectively, on the condensed consolidated balance sheets.

	Financial instruments are categorized in the Level 3 valuation hierarchy based on the significance of unobservable factors in the overall fair value measurement. Our fair value approach for Level 3 instruments primarily uses unobservable inputs, but may also include observable, actively quoted components derived from external sources. As a result, the realized and unrealized gains and losses for assets and liabilities within the Level 3 category presented in the tables below may include changes in fair value that were attributable to both observable and unobservable inputs.
	Loans, Notes and Certificates
	We use fair value measurements to record fair value adjustments to loans and the related notes and certificates that are recorded at fair value on a recurring basis. Loans and the related notes and certificates do not trade in an active market with readily observable prices. Accordingly, the fair value of loans and the related notes and certificates are determined using a discounted cash flow methodology utilizing assumptions market participants use for credit losses, changes in the interest rate environment and other factors. Fair value measurements of our loans and the related notes and certificates use significant unobservable inputs and, accordingly, we classify them as Level 3.
	At June 30, 2014 and December 31, 2013, loans and notes and certificates (in thousands) were:
			Loans							Notes and Certificates
			June 30, 2014			December 31, 2013				June 30, 2014			December 31, 2013
	Aggregate principal balance outstanding		$	2,351,515		$	1,849,042			$	2,361,902		$	1,859,982
	Fair value adjustments			(25,313	)		(20,000	)			(25,307	)		(19,992	)
	Fair Value		$	2,326,202		$	1,829,042			$	2,336,595		$	1,839,990
	Loans facilitated by Springstone are held by the issuing bank on and after origination and are therefore not recorded on our condensed consolidated balance sheet.
	Loan Servicing Rights
	We use fair value measurements to record fair value adjustments to loan servicing rights that are recorded at fair value on a recurring basis. Loan servicing rights do not trade in an active market with readily observable prices. Accordingly, the fair value of loan servicing rights are determined using a discounted cash flow methodology utilizing assumptions market participants use for adequate servicing compensation, credit losses, discount rates and contractual fee income. Fair value measurements of our loan servicing rights use significant unobservable inputs and, accordingly, we classify them as Level 3.
	Significant Unobservable Inputs
	The following table presents quantitative information about the significant unobservable inputs used for our Level 3 fair value measurements at June 30, 2014 and December 31, 2013:
							June 30, 2014									December 31, 2013
							Range of Inputs									Range of Inputs
			Unobservable Input				Minimum					Maximum				Minimum		Maximum

	The valuation technique used for our Level 3 assets and liabilities is described below.
	Loans, Notes and Certificates
	Discounted cash flow – Discounted cash flow valuation techniques generally consist of developing an estimate of future cash flows that are expected to occur over the life of a financial instrument and then discounting those cash flows at a rate of return that results in the fair value amount.
	Significant unobservable inputs presented in the table above are those we consider significant to the estimated fair values of the Level 3 assets and liabilities. We consider unobservable inputs to be significant, if by their exclusion, the estimated fair value of the Level 3 asset or liability would be impacted by a significant percentage change, or based on qualitative factors such as the nature of the instrument and significance of the unobservable inputs relative to other inputs used within the valuation. The following is a description of the significant unobservable inputs provided in the table.
	Discount rate – Discount rate is a rate of return used to discount future expected cash flows to arrive at a present value, the fair value, of the loans, notes and certificates. The discount rates for the projected net cash flows of loans are our estimates of the rates of return that investors in unsecured consumer credit obligations would require when investing in the various credit grades of loans. The discount rates for the projected net cash flows of the notes and certificates are our estimates of the rates of return that investors in unsecured consumer credit obligations would require when investing in notes and certificates with cash flows dependent on specific grades of loans. Discount rates for existing loans, notes and certificates are adjusted to reflect the time value of money. A risk premium component is implicitly included in the discount rates to reflect the amount of compensation market participants require due to the uncertainty inherent in the instruments’ cash flows resulting from risks such as credit and liquidity.
	Net cumulative expected loss – Net cumulative expected loss is an estimate of the net cumulative principal payments that will not be repaid over the entire life of a loan, note or certificate, expressed as a percentage of the original principal amount of the loan, note or certificate. The estimated net cumulative loss is the sum of the net losses estimated to occur each month of the life of a new loan, note or certificate. Therefore, the total net losses estimated to occur over the remaining maturity of existing loans, notes and certificates are less than the estimated net cumulative losses of comparable new loans, notes and certificates. A given month’s estimated net losses are a function of two variables:
		(i)	estimated default rate, which is an estimate of the probability of not collecting the remaining contractual principal amounts owed and,
		(ii)	estimated net loss severity, which is the percentage of contractual principal cash flows lost in the event of a default, net of the average net recovery, expected to be received on a defaulted loan, note or certificate.
	Our obligation to pay principal and interest on any note or certificate is equal to the pro-rata portion of the payments, if any, received on the related loan subject to applicable fees. The gross effective interest rate associated with notes or certificates is the same as the interest rate paid on the underlying loan. At June 30, 2014, the discounted cash flow methodology used to estimate the notes’ and certificates’ fair values uses the same projected net cash flows as their related loan. The discount rates for the projected net cash flows of the notes and certificates are our estimates of the rates of return, including risk premiums (if significant) that investors in unsecured consumer credit obligations would require when investing in notes and certificates with cash flows dependent on specific credit grades of loans.
	The following table presents additional information about Level 3 loans, notes and certificates measured at fair value on a recurring basis for the six months ended June 30, 2014 (in thousands):
			Loans			Notes and
						Certificates

	Issuances of notes and certificates			—			1,001,976

	Whole loan sales			(631,959	)		—
	Recoveries and sales of charged-off loans			(2,584	)		(2,564	)
	Carrying value before fair value adjustments			2,377,356			2,387,703
	Fair value adjustments, included in earnings			(51,154	)		(51,108	)
Fair value at June 30, 2014		$	2,326,202		$	2,336,595
At June 30, 2014, outstanding loans underlying notes and certificates have original terms between 12 months and 60 months and are paid monthly with fixed interest rates ranging from 5.42% to 29.90% and various maturity dates through June 2019.
The fair value of loans and the related notes and certificates are determined using a discounted cash flow model utilizing estimates for credit losses, changes in the interest rate environment, and other factors. For notes and certificates, we also consider risk factors such as our ability to operate on a cash-flow positive basis and liquidity position. The majority of fair value adjustments included in earnings is attributable to changes in estimated instrument-specific future credit losses. All fair valuation adjustments were related to Level 3 instruments for the six months ended June 30, 2014 and 2013. A specific loan that is projected to have higher future default losses than previously estimated has lower expected future cash flows over its remaining life, which reduces its estimated fair value. Conversely, a specific loan that is projected to have lower future default losses than previously estimated has increased expected future cash flows over its remaining life, which increases its fair value. Because the payments to holders of notes and certificates directly reflect the payments received on loans, a reduction or increase of the expected future payments on loans will decrease or increase the estimated fair values of the related notes and certificates. Expected losses and actual loan charge-offs on loans are offset to the extent that the loans are financed by notes and certificates that absorb the related loan losses.
The fair value adjustments for loans were largely offset by the fair value adjustments of the notes and certificates due to the member payment dependent design of the notes and certificates and because the total principal balances of the loans were very close to the combined principal balances of the notes and certificates.
We place loans on non-accrual status once they are 120 days past due or if the borrower has filed for bankruptcy or is deceased. At June 30, 2014, we had 1,032 loans that were 90 days or more past due which had a total outstanding principal balance of $11.9 million, aggregate adverse fair value adjustments totaling $10.9 million and an aggregate fair value of $1.0 million. At June 30, 2014, we had 42 loans that were over 120 days past due and classified as non-accrual loans, which had a total outstanding principal balance of $0.5 million, aggregate adverse fair value adjustments totaling $0.4 million and an aggregate fair value of $0.1 million.
At December 31, 2013, we had 989 loans that were 90 days or more past due which had a total outstanding principal balance of $10.2 million, aggregate adverse fair value adjustments totaling $9.1 million and an aggregate fair value of $1.1 million. At December 31, 2013, we had 111 loans that were over 120 days past due and classified as non-accrual loans, which had a total outstanding principal balance of $1.1 million, aggregate adverse fair value adjustments totaling $0.9 million and an aggregate fair value of $0.2 million.
Loan Servicing Rights
Discounted cash flow – Discounted cash flow valuation techniques generally consist of developing an estimate of future cash flows that are expected to occur over the life of a financial instrument and then discounting those cash flows at a rate of return that results in the fair value amount.
Significant unobservable inputs presented in the table above are those we consider significant to the estimated fair values of the Level 3 assets and liabilities. We consider unobservable inputs to be significant, if by their exclusion, the estimated fair value of the Level 3 asset or liability would be impacted by a significant percentage change, or based on qualitative factors such as the nature of the instrument and significance of the unobservable inputs relative to other inputs used within the valuation. The following is a description of the significant unobservable inputs provided in the table.
Market servicing rate – The Company estimates an adequate servicing compensation assumption as a measure of what a market participant would earn to service the loans that we sell to third parties. The Company estimated this market servicing rate based on observable market rates for other loan types in the industry, adjusted for the unique loan attributes that are present in such loans the Company sells (i.e., unsecured fixed rate fully amortizing loans, ACH loan payments, intermediate terms, prime credit grades and sizes) and a market servicing benchmarking analysis performed by an independent valuation firm.
Discount rate – Discount rate is a rate of return used to discount future expected cash flows to arrive at a present value, the fair value, of the loan servicing rights. The discount rates for the projected net cash flows of loan servicing rights are our estimates of the rates of return that investors in servicing rights for unsecured consumer credit obligations would require for the various credit grades of the underlying loans. Discount rates for servicing rights on existing loans are adjusted to reflect the time value of money. A risk premium component is implicitly included in the discount rates to reflect the amount of compensation market participants require due to the uncertainty inherent in the instruments’ cash flows resulting from risks such as credit and liquidity.
Net cumulative expected loss – Net cumulative expected loss is an estimate of the net cumulative principal payments that will not be repaid over the entire life of a loan expressed as a percentage of the original principal amount of the loan. The estimated net cumulative loss is the sum of the net losses estimated to occur each month of the life of a new loan. A given month’s estimated net losses are a function of two variables:
	(i)	estimated default rate, which is an estimate of the probability of not collecting the remaining contractual principal amounts owed and,
	(ii)	estimated net loss severity, which is the percentage of contractual principal cash flows lost in the event of a default, net of the average net recovery, expected to be received on a defaulted loan.
The following table presents additional information about Level 3 servicing assets and liabilities measured at fair value on a recurring basis for the six months ended June 30, 2014 (in thousands):
		Servicing			Servicing
		Assets			Liabilities
Fair value at December 31, 2013		$	534		$	936
Additions			1,159			1,655
Changes in fair value due to:
Realization of expected cash flows			(286	)		(560	)
Changes in market inputs or assumptions used in the valuation model			(373	)		705
Fair value at June 30, 2014		$	1,034		$	2,736
At June 30, 2014, outstanding loans underlying loan servicing rights have original terms between 36 months and 60 months and are paid monthly with fixed interest rates ranging from 6.00% to 26.06% and various maturity dates through June 2019.
Significant Recurring Level 3 Fair Value Asset and Liability Input Sensitivity
The discounted cash flow valuation technique that we use to determine the fair value of our Level 3 loans, notes and certificates requires determination of relevant inputs and assumptions, some of which represent significant unobservable inputs as described above. Accordingly, changes in these unobservable inputs may have a significant impact on fair value. Certain of these unobservable inputs will (in isolation) have a directionally consistent impact on the fair value of the instrument for a given change in that input. Alternatively, the fair value of the instrument may move in an opposite direction for a given change in another input. For example, increases in the discount rates and estimated net cumulative loss rates each will reduce the estimated fair value of loans, notes and certificates. When multiple inputs are used within the valuation technique of a loan, note or certificate, a change in one input in a certain direction may be offset by an opposite change in another input.
The discounted cash flow valuation technique we use determine the fair value of Level 3 loan servicing rights requires certain significant unobservable inputs including adequate servicing compensation, net cumulative loss rates, and discount rates. An increase in any of these unobservable inputs will reduce the fair value of the loan servicing rights and alternatively, a decrease in any one of these inputs would result in the loan servicing rights increasing in value.

Springstone Acquisition	'
	7. Springstone Acquisition
	On April 17, 2014, we acquired all of the outstanding limited liability company interests of Springstone (the “Acquisition”). As a result of the closing of the acquisition, Springstone is now a wholly owned subsidiary of Lending Club.
	Springstone facilitates financing options for consumers looking to finance education or private medical expenses through an active network of over 3,300 aggregate schools and healthcare providers, as of August 1, 2014 on behalf of two issuing banks. Springstone earns fee revenue from providers for facilitating loans to their customers and/or transaction fees from the issuing banks. The acquisition of Springstone expands the services we offer. We have included the financial results of Springstone in the condensed consolidated financial statements from the date of acquisition.
	Under the terms of the purchase agreement, the sellers received at the closing an aggregate of $113 million in cash and $25 million worth of shares of Lending Club’s Series F Preferred Stock (the “Share Consideration”). In connection with the acquisition, we also paid $2.4 million for transaction costs incurred by Springstone. For accounting purposes the purchase price was $111.9 million which was comprised of $109.1 million in cash and $2.8 million of Share Consideration. Additionally, a total of $25.6 million comprised of $22.1 million of Share Consideration and $3.5 million of cash was placed in a third party escrow, and is subject to certain vesting and forfeiture conditions applicable to certain key continuing employees over a three-year period from the closing. This will be accounted for as a compensation arrangement and expensed over the three-year vesting period.
	The cash portion of the consideration was funded by a combination of cash from Lending Club and proceeds from a debt financing and Series F preferred stock financing (see Note 10 – Term Loan and Note 11 – Stockholders’ Equity—Convertible Preferred Stock).
	We have completed the allocation of the purchase price to acquired assets and liabilities with the exception of finalizing the determination of certain contingent liabilities and the finalization of a revenue refund liability, any deferred tax asset or liability and the net working capital balance as of the acquisition date. The preliminary purchase price allocation is as follows (in thousands):
			Fair Value

	Liabilities:
	Accounts payable			239
	Accrued expenses and other liabilities			5,449
	Total purchase consideration		$	111,907
	The goodwill balance is primarily attributed to expected operational synergies, the assembled workforce, and the future development initiatives of the assembled workforce. Goodwill is expected to be deductible for U.S. income tax purposes.
	The amounts of revenue and earnings(losses) of Springstone included in the Company’s condensed consolidated statement of operations from the acquisition date of April 17, 2014 to June 30, 2014 were $4.7 million and $(1.7) million, respectively. We have recognized acquisition-related costs of $1.1 million and $2.3 million for the three and six months ended June 30, 2014, respectively and have reported this in general and administrative expense. We did not recognize acquisition-related costs for the three and six months ended June 30, 2013.

	In connection with the Springstone acquisition, Lending Club entered into a Credit and Guaranty Agreement (the “Credit Agreement”) with a series of banks (the “Lenders”) on April 16, 2014, under which the Lenders made a $50.0 million term loan to Lending Club (the “Term Loan”). In connection with the Credit Agreement, Lending Club entered into a Pledge and Security Agreement with Morgan Stanley Senior Funding, Inc. as Collateral Agent (the “Pledge and Security Agreement”).
	The Term Loan matures on April 16, 2017 and requires principal payments of $312,500 per quarter, with the remaining then unpaid principal amount payable at maturity. The Term Loan can be prepaid at any time without premium or penalty, subject to a minimum prepayment of $1.0 million. The Term Loan is required to be prepaid in certain circumstances, including upon sales of assets other than loans and upon the issuance of debt or redeemable capital stock.
	Borrowings under the Credit Agreement bear interest, which at the option of the Company may be either (a) a floating base rate tied to an underlying index plus an additional 1.25% per annum or (b) a Eurocurrency rate (for an interest period of one, two, three or six months) plus an additional 2.25% per annum (a “Eurocurrency Rate Loan”). The Term Loan was originally tied to the prime rate but was subsequently converted to a Eurocurrency rate. The weighted average interest rate on the Term Loan was 2.75% for both the three and six months ended June 30, 2014.
	The Term Loan is also guaranteed by Springstone and LCA and is secured by a first priority lien and security interest in substantially all of the Company’s and its subsidiaries’ assets, subject to certain exceptions.
	The Credit Agreement and Pledge and Security Agreement contain certain affirmative and negative covenants applicable to the Company and its subsidiaries. These include restrictions on the Company’s ability to make certain restricted payments, including restrictions on the Company’s ability to pay dividends, incur additional indebtedness, place liens on assets, merge or consolidate, make investments and enter into certain affiliate transactions. The Credit Agreement also requires Lending Club to maintain a maximum total leverage ratio (as defined in the Credit Agreement) of less than 5.50:1 initially, and decreasing to 3.50:1 after September 30, 2015 (on a consolidated basis). The total leverage ratio as of June 30, 2014 was 2.59.
	As of June 30, 2014, the carrying value of the Term Loan was $49.5 million. At June 30, 2014, the current portion of the Term Loan was $1.2 million and the noncurrent portion of the outstanding balance was $48.3 million. We did not have a Term Loan outstanding balance at December 31, 2013.
	In connection with the Term Loan, we capitalized $1.2 million of debt issuance costs. As of June 30, 2014, the net balance of debt issuance costs was $1.1 million. Interest expense on the Term Loan, including amortization of debt issuance cost, was $0.1 million during both the three and six months ended June 30, 2014. We did not have interest expense on the Term Loan for the three and six months ended June 30, 2013.

	For the three and six months ended June 30, 2014, we recorded $0.6 million of provision for income taxes. The $0.6 million of tax expense relates to the amortization of tax deductible goodwill from the Acquisition which gives rise to an indefinite-lived deferred tax liability. There was no income tax benefit recorded on the pre-tax loss due to an increase in deferred tax asset valuation allowance. The Company recorded a net provision of $0.1 million for income taxes for the three and six months ended June 30, 2013.
	Management assesses the available positive and negative evidence to estimate if sufficient future taxable income will be generated to utilize the existing deferred tax assets. On the basis of this evaluation, a full valuation allowance has been recorded to recognize only deferred tax assets that are more likely than not to be realized.
	At December 31, 2013, we had federal and state net operating loss (“NOL”) carry forwards of approximately $43.9 million and $40.7 million, respectively, to offset future taxable income. These federal and state net operating loss carry forwards will begin expiring in 2027 and 2016, respectively. Additionally, at December 31, 2013, we had federal and state research and development (“R&D”) tax credit carry forwards of approximately $0.6 million and $0.5 million, respectively. The federal credit carry forwards will begin expiring in 2016 and the state credits may be carried forward indefinitely.
	In general, a corporation’s ability to utilize its NOL and R&D carryforwards may be substantially limited due to ownership changes that may have occurred or that could occur in the future, as required by Section 382 of the Internal Revenue Code of 1986, as amended (the “Code”), as well as similar state provisions. These ownership changes may limit the amount of NOL and R&D credit carryforwards that can be utilized annually to offset future taxable income and tax, respectively. In general, an “ownership change,” as defined by Section 382 of the Code, results from a transaction or series of transactions over a three-year period resulting in an ownership change of more than 50 percent of the capital (as defined) of a company by certain stockholders or public groups.
	Due to the nature of the unrecognized tax benefits and the existence of tax attributes, we have not accrued any interest or penalties associated with unrecognized tax benefits in the condensed consolidated statement of operations nor have we recognized a liability in the condensed consolidated balance sheet.
	We do not believe the total amount of unrecognized tax benefit as of June 30, 2014, will increase or decrease significantly in the next twelve months.

	14. Net Income (Loss) Attributable to Common Stockholders
	Basic earnings (loss) per share (“EPS”) is the amount of earnings available to each share of common stock outstanding during the reporting period. Diluted EPS is the amount of earnings available to each share of common stock outstanding during the reporting period adjusted to include the effect of potentially dilutive common shares. Potentially dilutive common shares include incremental shares issued for stock options, convertible preferred stock and warrants. Potentially dilutive common shares are excluded from the computation of dilutive EPS in periods in which the effect would be antidilutive.
	We calculate EPS using the two-class method. The two-class method allocates earnings that otherwise would have been available to common shareholders to holders of participating securities. We consider all series of our convertible preferred stock to be participating securities due to their non-cumulative dividend rights. As such, earnings allocated to these participating securities, which include participation rights in undistributed earnings (see Note 11– Stockholders’ Equity), are subtracted from net income to determine total undistributed earnings to be allocated to common stockholders. All participating securities are excluded from basic weighted-average common shares outstanding.
	The following table details the computation of the basic and diluted net loss per share (in thousands, except share and per share data):

	We have operating lease agreements for space at 71 Stevenson Street in San Francisco, California, where our corporate headquarters are located. These leases expire in June 30, 2019 with a renewal option that would extend the leases for five years. We also have an operating lease agreement for space in Westborough, Massachusetts where Springstone is headquartered. This lease expires in January 31, 2020 with a renewal option that would extend the lease for five years.
	Total facilities rental expense for the three and six months ended June 30, 2014 was $0.9 million and $1.6 million, respectively. Total facilities rental expense for the three and six months ended June 30, 2013 was $0.4 million and $0.8 million, respectively. We did not have any sublease rental expense for the three and six months ended June 31, 2014. Sublease rental expense for the three and six months ended June 30, 2013 was $0.2 million and $0.4 million, respectively. Minimum rental expense for the three and six months ended June 30, 2014 was $0.8 million and $1.4 million, respectively. Minimum rental expense for the three and six months ended June 30, 2013 was $0.3 million and $0.6 million, respectively. As part of these lease agreements, we currently have pledged $0.2 million of cash and arranged for a $0.2 million letter of credit as security deposits.
	Loan Funding Commitments
	For loans listed on the platform as a result of direct marketing efforts, the Company has committed to invest in such loans if investors do not provide funding for all or a portion of such loans. At June 30, 2014, there were 427 such loans on the platform with an unfunded balance of $4.4 million. All of these loans were fully funded by investors by July 3, 2014.
	In connection with transitional activities related to the Acquisition, in June 2014 we entered into a contingent loan purchase agreement with an issuing bank that originates loans facilitated by Springstone and a third party investor that has agreed to purchase certain of those loans from such bank (“Contingent Loan Purchase Commitment”). The Contingent Loan Purchase Commitment provides that the Company will purchase such loans from the bank if the third party investor defaults on its loan purchase obligations to the bank through December 31, 2014. The Contingent Loan Purchase Commitment limits the aggregate amount of such loan originations from inception of the Contingent Loan Purchase Commitment through December 31, 2014 to a maximum of $5.0 million. As of June 30, 2014, the amount remaining under the overall limit on the cumulative amount of such loan originations through December 31, 2014 was $3.6 million. We were not required to purchase any such loans pursuant to the Contingent Loan Purchase Commitment in the quarter ended June 30, 2014. The Company does not expect we will be required to purchase any such loans under the Contingent Loan Purchase Commitment through its expiration on December 31, 2014.
	Credit Support Agreement
	We are subject to a credit support agreement with a Certificate investor. The credit support agreement requires us to pledge and restrict cash in support of this contingent obligation to reimburse the investor for credit losses on loans underlying the investor’s Certificate, that are in excess of a specified, aggregate loss threshold. The amount of cash to be pledged varies based on the investor’s Certificate purchase volume and cannot exceed $5.0 million. As of June 30, 2014, cash of $3.4 million was pledged and restricted to support this contingent obligation. The amount pledged and restricted to support this contingent obligation has not changed since July 31, 2013.
	As of June 30, 2014, the credit losses pertaining to the investor’s Certificate have not exceeded the specified threshold, nor are future credit losses expected to exceed the specified threshold, and thus no liability has been recorded. If losses related to the credit support agreement are later determined to be probable to occur and are reasonably estimable, results of operations could be affected in the period in which such losses are recorded.
	Legal
	We may be subject to legal matters and regulatory actions in the ordinary course of business. Certain of these matters are described below.
	In the second quarter of 2014, the Company offered to settle a dispute with a consultant that previously performed work for the Company. The Company offered the claimant a certain number of the Company’s common shares and cash consideration. Since part of this offer was in the form of the Company’s common shares, the Company valued the liability based on an estimated price of the common shares at June 30, 2014. If such offer is accepted by the claimant, the shares will be valued on the date of such agreement.
	Separately, during the second quarter of 2014, the Company received notice from the California Employment Development Department (“EDD”) that it had commenced an examination of the Company’s records concerning the employment relationship of certain individuals who performed services for the Company from 2011 through 2014. Based on the EDD’s preliminary determination, certain of these individuals should have been classified as employees with appropriate tax withholding and employer related taxes incurred and paid. The Company continues to evaluate a submission of a settlement offer to the EDD or whether it will pursue an appeal of any final notice of assessment that the EDD may levy against the Company with respect to misclassified individuals.
	Additionally, during the second quarter of 2014, a previous employee asserted a claim of wrongful termination. The Company offered to settle this claim during the second quarter of 2014.
	In connection with these matters, the Company recorded a charge in the second quarter of 2014 to operations in the aggregate amount of $1.8 million to establish a liability. This aggregate amount represents the Company’s probable estimate of tax and settlement liabilities. The ultimate liability for such matters could differ from the accrued liability at June 30, 2014. As of June 30, 2014, the Company estimates the aggregate range of reasonably possible losses in excess of any amounts accrued for these matters as of such date, to be up to approximately $0.7 million.
	The Company received a Civil Investigative Demand from the Consumer Financial Protection Bureau dated June 5, 2014 related to the operations of Springstone. The purpose of the investigation is to determine whether the Springstone is engaging in unlawful acts or practices in connection with the marketing, issuance, and servicing of installment loans for healthcare related financing. The Company continues to be in the fact-finding stage related to this matter, and as such, we have concluded that as of June 30, 2014, there are no probable or estimable losses related to this matter.
	In addition to the foregoing, the Company may be subject to legal proceedings and regulatory actions in the ordinary course of business. After consultation with legal counsel, the Company does not anticipate that the ultimate liability, if any, arising out of any such matter will have a material effect on its financial condition, results of operations or cash flows.

Goodwill and Intangible Assets	'
	Goodwill and Intangible Assets
	Goodwill represents the fair value of acquired businesses in excess of the fair value of the individually identified net assets acquired. Goodwill is not amortized but is tested for impairment annually or whenever indications of impairment exist. Our annual impairment testing date is April 1. We can elect to qualitatively assess goodwill for impairment if it is more likely than not that the fair value of a reporting unit (defined as business for which financial information is available and reviewed regularly by management) exceeds its carrying value. A qualitative assessment may consider macroeconomic and other industry-specific factors, such as trends in short-term and long-term interest rates and the ability to access capital, or company specific factors such as market capitalization in excess of net assets, trends in revenue generating activities and merger or acquisition activity.
	If we elect to bypass qualitatively assessing goodwill, or it is not more likely than not that the fair value of a reporting unit exceeds its carrying value, management will estimate the fair values of our reporting units and compare them to their carrying values. The estimated fair values of the reporting units will generally be established using an income approach based on a discounted cash flow model or a market approach which compares each reporting unit to comparable companies in their respective industries.
	Intangible assets are amortized over their useful lives in a manner that best reflects their economic benefit. Intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. We do not have any indefinite-lived intangible assets.
Servicing Asset/Liability	'
	Servicing Asset/Liability
	For whole loans sold to unrelated third party purchasers with servicing retained, we use a discounted cash flow model to estimate the fair value of the loan servicing asset or liability which considers the contractual servicing fee revenue we earn on the sold loans, an estimated market servicing rate to service such loans, the current principal balances of the loans and projected servicing revenues over the remaining terms of the loans. We record servicing assets and liabilities at their estimated fair values at the time the loans are sold. Changes in the estimated fair value of servicing assets and liabilities are reported in “Servicing Fees” in the period in which the change occurs. Servicing assets and liabilities are recorded in “Other Assets” and “Accrued Expenses and Other Liabilities”, respectively, on the condensed consolidated balance sheets.
