	1. Basis of Presentation
	The condensed consolidated financial statements as of March 31, 2014 and December 31, 2013 and for the three months ended March 31, 2014 and March 31, 2013, 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 months ended March 31, 2014 and 2013.
	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 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.
	The Company’s significant accounting policies are included in Note 2 – Summary of Significant Accounting Policies in the Company’s 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 three months of 2014.
	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.

Loans at Fair Value and Notes and Certificates at Fair Value	'
	2. Loans at Fair Value and Notes and Certificates at Fair Value
	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.
	We have ongoing monitoring procedures in place for our Level 3 assets and liabilities that use such valuation methods and models. These procedures are designed to provide reasonable assurance that internal valuation models continue to perform as expected after approved. All internal valuation models are subject to ongoing review by business-unit-level management and the executive management team.
	At March 31, 2014 and December 31, 2013, Loans and Notes and Certificates (in thousands) were:
			Loans								Notes and Certificates
			March 31, 2014				December 31, 2013				March 31, 2014				December 31, 2013
	Aggregate principal balance outstanding		$	2,131,152			$	1,849,042			$	2,141,557			$	1,859,982
	Fair value adjustments			(21,334	)			(20,000	)			(21,330	)			(19,992	)
	Fair Value		$	2,109,818			$	1,829,042			$	2,120,227			$	1,839,990
	We determined the fair values of Loans and Notes and Certificates using inputs and methods that are categorized in the fair value hierarchy, as follows (in thousands):
			Level 1 Inputs				Level 2 Inputs				Level 3 Inputs				Fair Value
	March 31, 2014
	Assets
	Loans at fair value		$	—			$	—			$	2,109,818			$	2,109,818

	Liabilities
	Notes and Certificates		$	—			$	—			$	1,839,990			$	1,839,990
	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.
	Significant Unobservable Inputs
	The following table presents quantitative information about the significant unobservable inputs used for our Level 3 fair value measurements at March 31, 2014:
					March 31, 2014								December 31, 2013
					Range of Inputs								Range of Inputs
			Unobservable Input		Minimum				Maximum				Minimum				Maximum
	Loans		Discount rate			5.6	%			16.9	%			5.9	%			15.9	%
			Net cumulative expected loss			2	%			21.6	%			2.1	%			23.7	%
	Notes & Certificates		Discount rate			5.6	%			16.9	%			5.9	%			15.9	%
			Net cumulative expected loss			2	%			21.6	%			2.1	%			23.7	%
	The valuation technique used for our Level 3 assets and liabilities, as presented in the previous table, is described as follows:
	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 March 31, 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 assets and liabilities measured at fair value on a recurring basis for the three months ended March 31, 2014 (in thousands):
			Loans				Notes and
							Certificates
	Fair value at December 31, 2013		$	1,829,042			$	1,839,990
	Purchases of Loans			776,801				—
	Issuances of Notes and Certificates			—				510,962
	Principal payments			(204,950	)			(205,274	)
	Whole Loan sales			(265,582	)			—
	Recoveries and sales of charged-off loans			(744	)			(734	)
	Carrying value before fair value adjustments			2,134,567				2,144,944
	Fair value adjustments, included in earnings			(24,749	)			(24,717	)
	Fair value at March 31, 2014		$	2,109,818			$	2,120,227
	At March 31, 2014, outstanding Loans underlying Notes and Certificates have original terms of either 36 months or 60 months and are paid monthly with fixed interest rates ranging from 5.42% to 26.06% and various maturity dates through March 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 three months ended March 31, 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.
	At March 31, 2014, we had 997 Loans that were 90 days or more past due including non-accrual loans and loans where the borrower has filed for bankruptcy or is deceased, which had a total outstanding principal balance of $10.5 million, aggregate adverse fair value adjustments totaling $9.5 million and an aggregate fair value of $1.0 million. At December 31, 2013, we had 989 Loans that were 90 days or more past due including non-accrual loans and loans where the borrower has filed for bankruptcy or is deceased, 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.
	Significant Recurring Level 3 Fair Value Asset and Liability Input Sensitivity
	The discounted cash flow 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 indicated in the preceding table. 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.

Stock-Based Compensation and Other Employee Benefit Plans	3 Months Ended
	Mar. 31, 2014
Stock-Based Compensation and Other Employee Benefit Plans	'
	8. Stock-Based Compensation and Other Employee Benefit Plans
	Stock Incentive Plan
	Under our 2007 Stock Incentive Plan (the “Option Plan”), we may grant options to purchase shares of common stock to employees, executives, directors and consultants at exercise prices not less than the fair market value on the date of grant for incentive stock options and not less than 85% of the fair market value on the date of grant for non-statutory options. An aggregate of 41,977,268 shares have been authorized for issuance under the Option Plan. The options granted through March 31, 2014 generally expire ten years from the date of grant and generally vest 25% twelve months from the date of grant, and quarterly thereafter, provided the grantee remains continuously employed by us through each vesting date (“service-based options”); however, the Board of Directors retains the authority to grant options with different terms.
	For the three months ended March 31, 2014, we granted service-based stock options to purchase 7,109,470 shares of common stock with a weighted average exercise price of $9.98 per share, a weighted average grant date fair value of $8.39 per share and a total estimated fair value of approximately $60 million.
	The fair value of the shares of common stock underlying stock options has historically been established by the Board of Directors primarily based upon a valuation provided by an independent third-party valuation firm. Because there is no public market for our common stock, our Board of Directors has relied upon this independent valuation and other factors, including, but not limited to, the current status of the technical and commercial success of our operations, our financial condition, the stage of our product design and development and our competition to establish the fair value of our common stock at the time of the option grant.
	We used the Black-Scholes option pricing model to estimate the fair value of stock options granted with the following assumptions:
		Three Months Ended March 31,
		2014			2013
	Assumed forfeiture rate (annual %)		5	%		5	%
	Expected dividend yield		0	%		0	%
	Weighted average assumed stock price volatility		54.7	%		63.5	%
	Weighted average risk-free rate		1.9	%		1.12	%
	Weighted average expected life (years)		6.33			6.25
	The assumed forfeiture rate is the annual percentage of unvested stock options that are assumed to be forfeited or cancelled due to grantees discontinuing employment with us. Because service-based stock options normally vest over a four year period, the forfeiture assumption is used to estimate the number of stock options that are expected to vest in future periods, which affects the estimate of the forfeiture-adjusted aggregate stock-based compensation expense related to the stock options. The forfeiture assumption was developed considering our actual annual forfeiture rates for unvested stock options over the past four years and analyzing the distribution of unvested stock options held by executive officers, senior managers and other employees as of March 31, 2014. Holding other assumptions constant, a higher forfeiture rate reduces the number of options expected to vest in future periods, which lowers the estimated forfeiture-adjusted aggregate stock-based compensation expense related to any affected stock options.
	We have paid no cash dividends and do not anticipate paying any cash dividends in the foreseeable future and therefore used an expected dividend yield of 0.0% in our option-pricing model.
	The stock price volatility assumption is derived using a set of peer group public companies. The peer group includes small-, mid- and large-capitalization companies that conduct business in the consumer finance, investment management and technology sectors.
	The expected life represents the period of time that stock options are estimated to be outstanding, giving consideration to the contractual terms of the awards and vesting schedules. Given our limited operating history, the simplified method was applied to calculate the expected term. The risk-free interest rate is based on the U.S. Treasury yield for a term consistent with the expected life of the awards in effect at the time of grant.
	Options activity under the Option Plan for the three months ended March 31, 2014 is summarized as follows:
		Stock Options Issued			Weighted
		and			Average
		Outstanding			Exercise Price
	Balances, December 31, 2013		21,657,364		$	1.88
	Options Granted		7,109,470			9.98
	Options Exercised		(719,562	)		1.08
	Options Forfeited/Expired		(558,376	)		3.69
	Balances, March 31, 2014		27,488,896		$	3.96
	Options to purchase 719,562 shares with a total intrinsic value (fair value less exercise price) of $6.4 million were exercised during the three months ended March 31, 2014.
	A summary of outstanding options, options vested and options vested and expected to vest as of March 31, 2014, is as follows:
		Stock Options Issued			Weighted Average			Weighted

	$0.01 - $10.00		27,488,896			8.35			8,838,852		25,894,148
	We recognized $7.3 million and $0.5 million of stock-based compensation expense related to stock options for the three months ended March 31, 2014 and 2013, respectively. For the three months ended March 31, 2014, we incurred $3.0 million of expense for the accelerated vesting of stock options for a terminated employee that was accounted for as a stock option modification and capitalized $0.3 million as internally developed software costs. For the three months ended March 31, 2013, we did not accelerate vesting of stock options or capitalize stock-based compensation as internally developed software costs.
	No net income tax benefit has been recognized relating to stock-based compensation expense and no tax benefits have been realized from exercised stock options.
	401(k) Plan
	We maintain a 401(k) defined contribution plan that covers substantially all of our employees. Participants may elect to contribute their annual compensation up to the maximum limit imposed by federal tax law. On April 15, 2014, we announced an employer 401(k) match up to 3% of an employee’s eligible earnings with a maximum annual match of $5,000 per employee.

	9. Income Taxes
	For the three months ended March 31, 2014 and 2013, respectively, we recorded no provision or benefit for income taxes due to a full valuation allowance against our deferred tax asset.
	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 March 31, 2014, will increase or decrease significantly in the next twelve months.

	10. 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 7– 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):
			Three Months Ended March 31,

	We have several operating lease agreements for space at 71 Stevenson Street in San Francisco, California, where our corporate headquarters are located. These leases expire in June 2019 with a renewal option that would extend the leases for five years to June 2024. In January 2014, we terminated a lease for our New York City office.
	Total facilities rental expense for the three months ended March 31, 2014 and 2013 was $0.7 million and $0.4 million, respectively. We did not have any sublease rental expense for the three months ended March 31, 2014. Sublease rental expense for the three months ended March 31, 2013 was $0.3 million. We did not have any minimum rental expense for the three months ended March 31, 2013. Minimum rental expense for the three months ended March 31, 2014 was $0.6 million. 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, we have committed to invest in such loans if investors do not provide funding for all or a portion of such loans. All loan listings obtained from direct marketing campaigns that were on the platform as of March 31, 2014 were fully funded by investors.
	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 March 31, 2014, approximately $3.4 million was pledged and restricted to support this contingent obligation.
	As of March 31, 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 pending legal proceedings and regulatory actions in the ordinary course of business. After consultation with legal counsel, we do not anticipate that the ultimate liability, if any, arising out of any such matter will have a material effect on our financial condition, results of operations or cash flows.

	On April 17, 2014, we acquired all of the outstanding limited liability company interests of Springstone Financial, LLC (“Springstone”), a Delaware limited liability company (the “Acquisition”). Springstone provides affordable financing options for consumers looking to finance private education and elective medical procedures through a network of over 14,000 schools and healthcare providers. The acquisition of Springstone expands the services we offer to help consumers achieve their goals.
	Under the terms of the Acquisition, the sellers received at closing an aggregate of $115.0 million in cash and approximately $25.0 million worth of shares of Lending Club’s Series F Preferred Stock (the “Share Consideration”). For accounting purposes the purchase price was $114.4 million which was comprised of $111.6 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 consideration will be accounted for as a compensation arrangement and expensed over the three-year vesting period. Springstone became a wholly owned subsidiary of Lending Club effective April 17, 2014.
	In connection with the Acquisition, on April 16, 2014, we sold an aggregate of 3,195,278 shares of its Series F Preferred Stock, par value $0.01 per share to certain new “accredited investors” (as defined under Rule 501 of Regulation D) for aggregate gross proceeds of approximately $65.0 million, pursuant to a Series F Preferred Stock Purchase Agreement dated April 16, 2014. Lending Club sold the shares pursuant to an exemption from registration under Section 4(a)(2) of the Securities Act of 1933, as amended; and Lending Club made no general solicitation for the sale of the Series F Preferred Stock. Series F Preferred Shares are convertible into shares of Lending Club common stock, par value $0.01 per share, on a one-for-one basis, as adjusted from time to time pursuant to the anti-dilution provisions of the Lending Club Restated Certificate of Incorporation.
	Additionally, on April 16, 2014, we entered into a Credit and Guaranty Agreement with joint lead arrangers and joint bookrunners led by Morgan Stanley Senior Funding, Inc., along with Credit Suisse Securities (USA) LLC, Silicon Valley Bank, Citicorp North America Inc., and JPMorgan Chase Bank, N.A., under which the Lenders agreed to make a $50.0 million term loan (the “Term Loan”) to Lending Club.
	The Term Loan was drawn in a single borrowing to partially finance the Acquisition and pay related fees and expenses, including fees and expenses related to the Credit and Guaranty Agreement. We may request that the Lenders establish new term loan facilities, provided that the aggregate principal amount of all new term loan facilities do not exceed $75.0 million. Unless the facility is so increased, no additional amounts are available for borrowing.
