Summary Of Significant Accounting Policies [Abstract]

Summary Of Significant Accounting Policies


1. Summary of Significant Accounting Policies
Nature of operations and basis of presentation		References in these notes to the unaudited condensed financial statements to "Organovo Holdings, Inc.," "Organovo Holdings," "we," "us," "our," "the Company" and "our Company" refer to Organovo Holdings, Inc. and its consolidated subsidiary Organovo, Inc. The Company has developed and is commercializing a platform technology for the generation of three-dimensional (3D) human tissues that can be employed in drug discovery and development, biological research, and as therapeutic implants for the treatment of damaged or degenerating tissues and organs. As of March 31, 2012, the Company has devoted substantially all of its efforts to product development, raising capital, and building infrastructure. The Company has not realized significant revenues from its planned principal operations. Accordingly, the Company is considered to be in the development stage. The accompanying interim condensed financial statements have been prepared by the Company, without audit, in accordance with the instructions to Form 10-Q and, therefore, do not necessarily include all information and footnotes necessary for a fair statement of its financial position, results of operations and cash flows in accordance with generally accepted accounting principles ("GAAP"). The balance sheet at December 31, 2011 is derived from the audited balance sheet at that date. In the opinion of management, the unaudited financial information for the interim periods presented reflects all adjustments, which are only normal and recurring, necessary for a fair statement of financial position, results of operations and cash flows. These financial statements should be read in conjunction with the financial statements included in the Company's Form 8-K/A for the fiscal year ended December 31, 2011 filed with the Securities and Exchange Commission (the "SEC") on May 11, 2012. Operating results for interim periods are not necessarily indicative of operating results for the Company's 2012 fiscal year.

Merger transaction		On February 8, 2012, Organovo, Inc., a privately held Delaware corporation, merged with and into Organovo Acquisition Corp., a wholly-owned subsidiary of the Company, a publicly traded Delaware corporation, with the Organovo, Inc. surviving the merger as a wholly-owned subsidiary of the Company (the "Merger"). As a result of the Merger, the Company acquired the business of the Organovo, Inc., and will continue the existing business operations of Organovo, Inc. Simultaneously with the Merger, on February 8, 2012 (the "closing date"), all of the issued and outstanding shares of Organovo, Inc.'s common stock converted, on a 1 for 1 basis, into shares of the Company's Common stock, par value $0.001 per share. Also on the closing date, all of the issued and outstanding options to purchase shares of Organovo, Inc.'s common stock and other outstanding warrants to purchase Organovo, Inc.'s common stock, and all of the issued and outstanding bridge warrants to purchase shares of Organovo, Inc.'s common stock, converted, respectively, on a 1 for 1 basis, into options, warrants and new bridge warrants to purchase shares of the Company's common stock. Immediately following the consummation of the Merger: (i) the former security holders of Organovo, Inc. common stock had an approximate 75% voting interest in the Company and the Company stockholders retained an approximate 25% voting interest, (ii) former executive management team of Organovo, Inc. remained as the only continuing executive management team for the Company, and (iii) the Company's ongoing operations consist solely of the ongoing operations of Organovo, Inc. Based primarily on these factors, the Merger was accounted for as a reverse merger and a recapitalization in accordance with GAAP. As a result, these financial statements reflect the historical results of Organovo, Inc. prior to the Merger, and the combined results of the Company following the Merger. The par value of Organovo, Inc. common stock immediately prior to the Merger was $0.0001 per share. The par value subsequent to the Merger is $0.001 per share, and therefore the historical results of Organovo, Inc. prior to the Merger have been retroactively adjusted to affect the change in par value. In connection with three separate closings of a private placement transaction completed in connection with the Merger (the "Private Placement"), the Company received gross proceeds of approximately $5,000,000, $1,800,000 and $6,900,000 on February 8, 2012, February 29, 2012 and March 16, 2012, respectively. The Company previously received $1,500,000 from the purchase of 6% convertible notes which were automatically converted into 1,500,000 shares of common stock, plus 25,387 shares for accrued interest of $25,387 on the principal, at February 8, 2012. See Note 3.


		The cash transaction costs related to the Merger were approximately $2,129,500. Before the Merger, Organovo Holdings' board of directors and stockholders adopted the 2012 Equity Incentive Plan (the "2012 Plan"). The 2012 Plan provides for the issuance of 6,553,9856 shares of the Company's Common stock to executive officers, directors, advisory board members and employees. In addition, Organovo Holdings assumed and adopted Organovo, Inc.'s 2008 Equity Incentive Plan.

Liquidity		As of March 31, 2012, the Company had an accumulated deficit of approximately $43,772,000. The Company also had negative cash flow from operations of approximately $3,556,000 during the three months ended March 31, 2012. On February 8, 2012, the Company received gross proceeds of approximately $5,000,000 in a private placement offering in conjunction with the Merger. On February 29, 2012 and March 16, 2012, the Company completed two additional closings of its Private Placement and received total gross proceeds of approximately $8,722,000. The Company expects to cover its anticipated operating expenses over the next twelve months through cash on hand including the funds raised during the first quarter of 2012 through the Private Placement of its securities and funds received through collaborative agreements, and other commercial arrangements. The Company's ability to continue its operations is dependent upon its ability to raise additional capital through equity or debt financing, and to generate capital through collaborative research agreements and other commercial arrangements. There can be no assurance that any additional financing will be available on acceptable terms or available at all. Any equity financing may result in dilution to existing stockholders and any debt financing may include restrictive covenants. The accompanying financial statements do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts and classification of liabilities that may result from the outcome of these uncertainties.


Use of estimates		The preparation of the financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect certain reported amounts and disclosures. Accordingly, actual results could differ from those estimates. Significant estimates used in preparing the financial statements include those assumed in computing the valuation of warrants and conversion features, revenue recognized under the proportional performance model, the valuation of stock-based compensation expense, and the valuation allowance on deferred tax assets.

Cash and cash equivalents		The Company considers all highly liquid investments with original maturities of 90 days or less to be cash equivalents.

Restricted cash		As of March 31, 2012, the Company had $38,290 of restricted cash deposited with a financial institution, held in certificates of deposit to support a letter of credit agreement related to the facility lease entered into during 2012.

Inventory		Inventories are stated at the lower of the cost or market (first-in, first out). Inventory at March 31, 2012 consisted of approximately $279,000 in finished goods and approximately $58,000 in raw materials. Inventory at December 31, 2011 consisted of approximately $235,000 in finished goods and approximately $56,900 in raw materials. The Company provides inventory allowances based on excess or obsolete inventories determined based on anticipated use in the final product. There was no obsolete inventory reserve as of March 31, 2012 or December 31, 2011.

Deferred financing costs		As of December 31, 2011, deferred financing costs consisted of approximately $140,000 associated with the Merger transaction and approximately $179,000 associated with convertible notes as part of the private placement offering that was initiated in the fourth quarter of 2011. The deferred financing costs related to the private placement offering were amortized over the life of the convertible notes and fully amortized to expense upon conversion of the convertible notes on February 8, 2012. The deferred financing costs associated with the Merger transaction in excess of the proceeds received were expensed at the effective Merger date. As of March 31, 2012, there were no deferred financing costs.

Fixed assets and depreciation		Property and equipment are carried at cost. Expenditures that extend the life of the asset are capitalized and depreciated. Depreciation and amortization are provided using the straight-line method over the estimated useful lives of the related assets or, in the case of leasehold improvements, over the lesser of the useful life of the related asset or the lease term. The estimated useful life of the fixed assets range between three and ten years.

Impairment of long-lived assets		In accordance with authoritative guidance the Company reviews its long-lived assets, including property and equipment and other assets, for impairment whenever events or changes in circumstances indicate that the carrying amounts of the assets may not be fully recoverable. To determine recoverability of its long-lived assets, the Company evaluates whether future undiscounted net cash flows will be less than the carrying amount of the assets and adjusts the carrying amount of its assets to fair value. Management has determined that no impairment of long-lived assets occurred in the period from inception through March 31, 2012.

Fair value measurement		Financial assets and liabilities are measured at fair value, which is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The following is a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value:

¨ Level 1 — Quoted prices in active markets for identical assets or liabilities.

¨ Level 2 — Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

¨ Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

As of March 31, 2012 and December 31, 2011, cash and cash equivalents were comprised of cash in checking accounts.

The Company used Level 3 inputs for its valuation methodology for the warrant derivative liabilities. The estimated fair values were determined using a Monte Carlo option pricing model based on various assumptions (see Note 2). The Company's derivative liabilities are adjusted to reflect estimated fair value at each period end, with any decrease or increase in the estimated fair value being recorded in other income or expense accordingly, as adjustments to fair value of derivative liabilities.

At March 31, 2012, the estimated fair values of the liabilities measured on a recurring basis are as follows:

Fair Value Measurements at March 31, 2012


	Balance at March, 31, 2012		Quoted Prices in Active Markets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Other Unobservable Inputs (Level 3)
Warrant liability	$	47,514,710		—		—	$	47,514,710

The following table presents the activity for liabilities measured at estimated fair value using unobservable inputs for the three months ended March 31, 2012:

	Warrant Derivative Liability
Beginning balance at December 31, 2011	$	1,266,869
Issuances		32,742,022
Adjustments to estimated fair value		13,505,819

Ending balance at March 31, 2012	$	47,514,710


Revenue recognition		Research and Development Revenue Under Collaborative Agreements. In December 2010, the Company entered into a 12 month research contract agreement with a third party, whereby the Company was engaged to perform research and development services on a fixed-fee basis for approximately $600,000. Based on the proportional performance criteria, the Company recognized approximately $0 and $74,000 in revenue related to the contract during three months ended March 31, 2012 and 2011, respectively. Total revenue recognized on the contract from inception through March 31, 2012 was approximately $450,000. In October 2011, the Company entered into a research contract agreement with a third party, whereby the Company will perform research and development services on a fixed-fee basis for $1,365,000. The agreement included an initial payment to the Company of approximately $239,000, with remaining payments expected to occur over a 21-month period. During the period ended March 31, 2012, the Company recorded approximately $120,000 in revenue related to the research contract in recognition of the proportional performance achieved by the Company during the first quarter of 2012. Total revenue recognized on the contract from inception through March 31, 2012 was approximately $359,000. NIH and U.S. Treasury Grant Revenues During 2010, the U.S. Treasury awarded the Company two one-time grants totaling approximately $397,300 for investments in qualifying therapeutic discovery projects under section 48D of the Internal Revenue Code. The grants cover reimbursement for qualifying expenses incurred by the Company in 2010 and 2009. The proceeds from these grants are classified in "Revenues – Grants" for the period from inception through March 31, 2012. During 2010 and 2009, the NHLBI, a division of the NIH, awarded the Company two research grants totaling approximately $268,000. Revenues from the NIH grants are based upon internal and subcontractor costs incurred that are specifically covered by the grant, and where applicable, an additional facilities and administrative rate that provides funding for overhead expenses. These revenues are recognized when expenses have been incurred by subcontractors and as the Company incurs internal expenses that are related to the grant. Revenue recognized under these grants for the three months ended March 31, 2012 and 2011 was approximately $0 and $27,000, respectively. Total revenue recorded under these grants from inception through March 31, 2012 was approximately $268,000. Billings to customers or payments received from customers are included in deferred revenue on the balance sheet until all revenue recognition criteria are met. As of March 31, 2012 and December 31, 2011, the Company had approximately $268,900 and $152,500 in deferred revenue related to its collaborative research programs.

Net loss per share		Net loss per share is presented as both basic and diluted net loss per share. Basic net loss per share excludes any dilutive effects of options, shares subject to repurchase and warrants. Diluted net loss per share includes the impact of potentially dilutive securities. No dilutive effect was calculated for the three months ended March 31, 2012 and 2011 as the Company reported a net loss for each respective period and the effect would have been anti-dilutive. The Company had outstanding common share equivalents of 25,817,738 and 2,243,350 at March 31, 2012 and 2011, respectively.

Derivative Liability [Abstract]

Derivative Liability

2. Derivative Liability

During 2012, in relation to the reverse Merger and the three offerings under the Private Placement, the Company issued 21,347,182 five-year warrants to purchase the Company's Common stock. The exercise price of the warrants is protected against down-round financing throughout the term of the warrant, as described below. The terms of the warrants issued in the first quarter of 2012 are the same as those issued in connection with the convertible notes in October and November 2011. Pursuant to ASC 815-15 and ASC 815-40, the fair value of the warrants of approximately $32,742,000 was recorded as a derivative liability on the issuance dates.

As of December 31, 2011, the Company had a warrant liability of $1,266,869 related to 1,500,000 warrants issued with Convertible Notes in the fourth quarter of 2011.

The Company revalued all of the warrants at the end of the period, and the estimated fair value of the warrant liabilities is $47,514,710 at March 31, 2012. The change in fair value of the derivative liabilities of approximately $13,505,800 is included in other expense in the 2012 statement of operations.

The derivative liabilities were valued at the closing dates of the Private Placement at March 31, 2012 using a Monte Carlo valuation model with the following assumptions:


	Closing dates		March 31, 2012
Closing price per share of common stock	$	N/A	$	2.47
Exercise price per share	$	1.00	$	1.00
Expected volatility		105.8%-110.5%		103.5	%
Risk-free interest rate		0.82%-1.07%		1.04	%
Dividend yield		—		—
Remaining expected term of underlying securities (years)		5		4.90

In addition, as of the valuation dates, management assessed the probabilities of future financings assumptions in the Monte Carlo valuation models. Management also applied a discount for lack of marketability to the valuation of the derivative liabilities based on such trading restrictions due to the shares not being registered.

If, prior to the expiration date of the warrants, the Company issues additional shares of Common Stock, as defined below, without consideration or for a consideration per share less than the exercise price of the warrants in effect immediately prior to such issue, then the exercise price shall be reduced, concurrently with such issue, to a price (calculated to the nearest cent) determined by multiplying such exercise price by a fraction, (A) the numerator of which shall be (1) the number of shares of Common stock outstanding immediately prior to such issue plus (2) the number of shares of Common stock which the aggregate consideration received or to be received by the Company for the total number of additional shares of Common stock so issued would purchase at such exercise price; and (B) the denominator of which shall be the number of shares of Common stock outstanding immediately prior to such issue plus the number of such additional shares of Common stock so issued; provided that (i) all shares of Common stock issuable upon conversion or exchange of convertible securities outstanding immediately prior to such issue shall be deemed to be outstanding, and (ii) the number of shares of Common stock deemed issuable upon conversion or exchange of such outstanding convertible securities shall be determined without giving effect to any adjustments to the conversion or exchange price or conversion or exchange rate of such convertible securities resulting from the issuance of additional shares of Common stock that is the subject of this calculation. For purposes of the warrants, "additional shares of common stock" shall mean all shares of Common stock issued by the Company after the effective date (including without limitation any shares of Common stock issuable upon conversion or exchange of any convertible securities or upon exercise of any option or warrant, on an as-converted basis), other than: (i) shares of Common stock (and/or warrants for any class of equity securities of the Company) issued or issuable upon conversion or exchange of any convertible securities or exercise of any options or warrants outstanding on the effective date; (ii) shares of Common stock issued or issuable by reason of a dividend, stock split, split-up or other distribution on shares of Common stock; (iii) shares of Common stock (or options with respect thereto) issued or issuable to employees or directors of, or consultants to, the Company or any of its subsidiaries pursuant to a plan, agreement or arrangement approved by the Board of Directors of the Company; (iv) any securities issued or issuable by the Company pursuant to (A) the Private Placement; or (B) the Merger; (v) securities issued pursuant to acquisitions or strategic transactions approved by a majority of disinterested directors of the Company, provided that any such issuance shall only be to a person which is, itself or through its subsidiaries, an operating company in a business synergistic with the business of the Company and in which the Company receives benefits in addition to the investment of funds, but shall not include a transaction in which the Company is issuing securities primarily for the purpose of raising capital or to an entity whose primary business is investing in securities and (vi) securities issued to financial institutions, institutional investors or lessors in connection with credit arrangements, equipment financings or similar transactions approved by a majority of disinterested directors of the Company, but shall not include a transaction in which the Company is issuing securities primarily for the purpose of raising capital or to an entity whose primary business is investing in securities.

Upon each adjustment of the exercise price pursuant to the provisions stated above, the number of warrant shares issuable upon exercise of the warrants shall be adjusted by multiplying a number equal to the exercise price in effect immediately prior to such adjustment by the number of warrant shares issuable upon exercise of the warrant immediately prior to such adjustment and dividing the product so obtained by the adjusted exercise price.

Convertible Notes Payable

Convertible Notes Payable [Abstract]

Convertible Notes Payable

3. Convertible Notes Payable

Convertible notes		At December 31, 2011, an unsecured $100,000 Convertible Note, with interest at 10% and a maturity date of April 2014, remained outstanding. In February 2012, at the close of the Merger, the convertible note and accrued interest of approximately $110,740 were repaid.


Private placement		On September 18, 2011, Organovo, Inc.'s Board of Directors authorized a private placement offering of up to 30 units of its securities at a price of $50,000 per unit for an aggregate purchase price of $1,500,000. Each unit consisted of a convertible note in the principal amount of $50,000 accruing simple interest at the rate of 6% per annum (the "Convertible Notes"), plus five-year warrants to purchase 50,000 shares of the next Qualified Round of Equity Securities, at an exercise price of $1.00 per share. The principal plus accrued interest was convertible into the Company's common stock upon consummation of the Merger. During October and November 2011, $1,500,000 of Convertible Notes bearing interest at 6% per annum with a maturity date of March 30, 2012, and five-year warrants to purchase 1,500,000 shares of the Company's Common stock were issued to investors under the Private Placement. The warrants are exercisable at $1.00 per share, expire in five years, and contain down-round price protection. The Convertible Notes were outstanding at December 31, 2011, and were converted into 1,525,387 units during February 2012, in connection with the Merger. The Company determined that the warrants represent a derivative instrument due to the down-round price protection, and accordingly, the Company recorded a derivative liability related to the warrants. See Note 4. Additionally, during 2011 at issuance of the notes, the Company recorded the discount for the beneficial conversion feature of $239,700. The debt discount associated with the warrants and beneficial conversion feature were amortized to interest expense over the life of the Convertible Notes, and fully amortized upon conversion of the Convertible Notes. The Company recorded approximately $896,200 of interest expense for the amortization of the debt discount during the three months ended March 31, 2012 and approximately $1,500,000 for the period from inception through March 31, 2012. As consideration for locating investors to participate in the Private Placement, the placement agent earned a cash payment of $195,000. Additionally, upon closing of the Merger transaction, the placement agent earned five-year warrants to purchase 610,155 shares of the Company's Common stock at $1.00 per share. These warrants contain down round protection and were classified as derivative liabilities upon issuance. See Note 2. Interest expense, including amortization of the note discounts, for the three months ended March 31, 2012 and 2011 was approximately $1,087,453 and $53,100, respectively. Interest expense, including amortization of the note discounts, for the period from April 19, 2007 (inception) through December 31, 2011 was approximately $3,405,895. During 2012, concurrently with the closing of the Merger and in contemplation of the Merger, the Company completed the initial closing of the Private Placement of up to 8,000,000 units of its securities, at a price of $1.00 per unit, with the ability to increase the offering to an aggregate of up to 16,000,000 units. Each unit consisted of one share of Common Stock and a warrant to purchase one share of Common Stock. The Company completed three closings under the Private Placement during the three months ended March 31, 2012, and raised total gross proceeds of $13,722,600 and total net proceeds of $11,593,066. The Company issued 13,722,600 shares of its Common Stock and warrants to purchase 15,247,987 shares of its Common Stock (including warrants to purchase 1,525,387 shares to former holders of the bridge notes) exercisable at $1.00 to investors in the Offering. The placement agent and its selected dealers were paid total cash commissions of $1,372,260 and the Placement Agent was paid an expense allowance of $411,678 and was issued Placement Agent warrants to purchase 6,099,195 shares of the Company's Common Stock at an exercise price of $1.00 per share. The warrants issued to the investors and the placement agent, as described above, contain down round protection, and accordingly, were classified as derivative liabilities upon issuance. On the closing date, the derivative liabilities were recorded at an estimated fair value of approximately $32,742,000. Given that the fair value of the derivative liabilities exceeded the total proceeds of the private placement of $13,722,600, no net amounts were allocated to the common stock. The amount by which the recorded liabilities exceeded the proceeds of approximately $19,019,400 was charged to other expense at the closing dates. The Company has revalued the derivative liability as of March 31, 2012, and will continue to do so on each subsequent balance sheet date until the securities to which to derivative liabilities relate are exercised or expire, with any changes in the fair value. See Note 2.

Registration rights agreement		The Company entered into a registration rights agreement (each, a "Registration Rights Agreement") with the investors in the Offering. Under the terms of the Registration Rights Agreement, the Company agreed to file a registration statement covering the resale of the Common Stock underlying the Units and the Common Stock that is issuable on exercise of the Investor Warrants (but not the Common Stock that is issuable upon exercise of the warrants issued as compensation to the placement agent in connection with the Offering) within 90 days from the final closing date of the Offering (the "Filing Deadline"), and shall use commercially reasonable efforts to cause the registration statement to become effective no later than 180 days after it is filed (the "Effectiveness Deadline"). The Company agreed to use reasonable efforts to maintain the effectiveness of the registration statement through the one year anniversary of the date the registration statement is declared effective by the Securities and Exchange Commission (the "SEC"), or until Rule 144 of the 1933 Act is available to investors in the Offering with respect to all of their shares, whichever is earlier. If the Company does not meet the Filing Deadline or Effectiveness Deadline, the Company will be liable for monetary penalties equal to one-half of one percent (0.5%) of each investor's investment in the offering at the end of every 30 day period following such Filing Deadline or Effectiveness Deadline failure until such failure is cured. The payment amount shall be prorated for partial 30 day periods. The maximum aggregate amount of payments to be made by the Company as the result of such shall be an amount equal to 6% of each investor's investment amount. Notwithstanding the foregoing, no payments shall be owed with respect to any period during which all of the investor's registrable securities may be sold by such investor under Rule 144 or pursuant to another exemption from registration.

Concentrations [Abstract]

Concentrations

6. Concentrations

Credit risk		Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of temporary cash investments. The Company maintains cash balances at various financial institutions primarily located in San Diego. Accounts at these institutions are secured by the Federal Deposit Insurance Corporation. At times, balances may exceed federally insured limits. The Company has not experienced losses in such accounts, and management believes that the Company is not exposed to any significant credit risk with respect to its cash and cash equivalents.

- Definition

The entire disclosure for any concentrations existing at the date of the financial statements that make an entity vulnerable to a reasonably possible, near-term, severe impact. This disclosure informs financial statement users about the general nature of the risk associated with the concentration, and may indicate the percentage of concentration risk as of the balance sheet date.
