| Description of Business |
Note 1. Description of Business Nature of operations Organovo Holdings, Inc. (“Organovo Holdings,” “we,” “us,” “our,” “the Company” and “our Company”) is a biotechnology company that has focused on pioneering the development of bioprinted human tissues that emulate human biology and disease. In August 2019, after a rigorous assessment of the Company’s lead liver therapeutic tissue program following completion of various preclinical studies, the Company’s Board of Directors (the “Board”) concluded that the variability of biological performance and related duration of potential benefits presented development challenges and lengthy redevelopment timelines that no longer supported an attractive opportunity for the Company and its stockholders. Furthermore, the Board deemed the stage of development of the Company’s other therapeutic pipeline assets, including stem cell based tissue programs, to be too premature to potentially reach IND filing status within an acceptable investment horizon and with the Company’s available resources. As a result, the Company suspended all development of its lead program and all other related pipeline development activity and engaged a financial advisory firm to explore its strategic alternatives, including evaluating a range of ways to generate value from the Company’s technology platform and intellectual property, its commercial and development capabilities, its listing on the Nasdaq Stock Market, and its remaining financial assets. These strategic alternatives may include possible mergers and business combinations, sales of part or all of the Company’s assets, and licensing arrangements. In connection with this process, the Company also implemented various restructuring steps to manage its resources and extend its cash runway, including halting all commercial activities, except for sales of primary human cells out of inventory, negotiating an exit from its long-term facility lease, selling various assets, and reducing its workforce to the minimum level necessary to explore and support these strategic alternatives. This strategic alternatives process is both active and ongoing, and includes a range of interactions with potential transaction counterparties, including both potential merger transactions, sales of the Company’s inventory and assets and potential licensing arrangements. We believe it is in our stockholders’ best interests at this time to continue to pursue one or more of these transactions, or other strategic alternatives we may identify in the near term. Although we are actively pursuing our strategic alternatives, there is no assurance that we will be able to successfully negotiate and consummate a transaction on a timely basis, or at all. Additionally, any transaction we consummate may offer limited value for our existing business and proprietary technology and may not enhance stockholder value or provide the expected benefits. Based on our current plans and available resources, we believe that we can maintain our current operations for at least the next 12 months, however, if we are unable to successfully complete a strategic transaction or secure additional capital on a timely basis and on terms that are acceptable to our stockholders, we may elect to cease our operations altogether. As the Company continues to pursue and evaluate its strategic alternatives and reorganizes its operational capacity, its operations and the trends and risks that apply to its business have changed from those that are described in the Company’s Annual Report on Form 10-K for the year ended March 31, 2019. Prior to August 2019, its business and historical operating results were based on its past operational contract services model and therapeutic tissue development programs which are not indicative of future results. In the event that the Company does engage in one or more strategic transactions, it is possible that the value realized by its stockholders in such transactions might be significantly less than the $31.1 million of stockholders’ equity recorded on its condensed consolidated financial statements as of September 30, 2019 for a number of factors, risks and uncertainties, including the fact that the Company will continue to realize a net loss through the closing of such a transaction. Except where specifically noted or the context otherwise requires, references to “Organovo Holdings,” “the Company,” “we,” “our,” and “us” in these notes to the unaudited condensed consolidated financial statements refers to Organovo Holdings, Inc. and its wholly owned subsidiaries, Organovo, Inc. and Samsara Sciences, Inc. |

| Summary of Significant Accounting Policies |
Note 2. Summary of Significant Accounting Policies Basis of presentation and principles of consolidation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not necessarily include all information and notes required by GAAP for complete financial statements. The condensed consolidated balance sheet at March 31, 2019 is derived from the Company’s audited consolidated balance sheet at that date. The unaudited condensed consolidated financial statements include the accounts of Organovo Holdings and its wholly owned subsidiaries. All material intercompany accounts and transactions have been eliminated in consolidation. 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 the Company’s financial position, results of operations, stockholders’ equity and cash flows. These unaudited condensed consolidated financial statements should be read in conjunction with the audited financial statements and notes included in the Company’s Annual Report on Form 10-K for the year ended March 31, 2019, as filed with the Securities and Exchange Commission (“SEC”). Operating results for interim periods are not necessarily indicative of operating results for the Company’s fiscal year ending March 31, 2020 (see “Note 1. Description of Business”). Liquidity As of September 30, 2019, the Company had cash and cash equivalents of approximately $30.4 million and restricted cash of approximately $0.1 million. The restricted cash was pledged as collateral for a letter of credit that the Company is required to maintain as a security deposit under the terms of the lease of its facilities. The Company had an accumulated deficit of approximately $273.4 million at September 30, 2019. The Company also had negative cash flows from operations of approximately $11.1 million during the six months ended September 30, 2019. Through September 30, 2019, the Company has financed its operations primarily through the sale of convertible notes, warrants, the private placement of equity securities, the sale of common stock through public and at-the-market (“ATM”) offerings, and through revenue derived from product and research service-based agreements, collaborative agreements, licenses, and grants. During the three and six months ended September 30, 2019, the Company issued 0 and 6,087,382 shares of its common stock through its ATM facility and received net proceeds of approximately $0 and $5.0 million, respectively. As we explore various strategic alternatives, we have taken steps to manage our resources and extend our cash runway including halting all commercial activities except for sales of primary human cells out of inventory, negotiating an exit from our long-term facility lease, selling various assets, and reducing our workforce to the minimum level necessary to explore and support these strategic alternatives. As a result, the Company terminated the employment of 46 employees, or 79% of its workforce and recorded a restructuring charge in the fiscal second quarter of approximately $2.5 million, primarily related to employee severance and benefits costs, of which $1.7 million was paid out during the fiscal second quarter and the remainder is anticipated to be paid out during the fiscal third quarter. The Company currently expects further restructuring actions tied to progress made on the strategic alternatives process, which could lead to an additional $3.1 million of severance and benefits costs that would be incurred and paid on or prior to a possible strategic transaction, of which $0.4 million is expected to be incurred during the Company’s fiscal third quarter, with the remainder to be incurred upon closing of a strategic transaction. As a result, absent any further impact from asset sales or merger related costs or other costs incurred from other strategic alternatives, the Company expects its cash balance to be between $28.0 million and $29.0 million at the end of its fiscal third quarter and between $26.0 million and $27.0 million at the end of its fiscal fourth quarter. Although the Company is actively pursuing strategic alternatives, there is no assurance that it will be able to successfully negotiate and consummate one or more transactions on a timely basis, or at all. Further, the Company’s expenses may exceed its current plans and expectations, which could cause the Company to complete a transaction or wind-down its operations sooner than anticipated. Additionally, any transaction the Company consummates may offer limited value for the Company’s existing business and proprietary technology and may not enhance stockholder value or provide the expected benefits. If the Company is unable to successfully complete a strategic transaction or secure additional capital on a timely basis and on terms that are acceptable to its stockholders, the Company may elect to cease its operations altogether, in which event the value realized by our stockholders might be significantly less than the $31.1 million of stockholders’ equity recorded on our consolidated financial statements as of September 30, 2019. While the Company believes that it can maintain its current operations for at least the next 12 months, based on its current plans and available resources, the assessment by the Company discussed above with respect to its strategic alternatives raises substantial doubt over the Company’s ability to successfully finance itself on a long-term basis. The accompanying consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty. 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 consolidated financial statements include those assumed in revenue recognition, the measurement of operating lease right-of-use assets and lease liabilities, the valuation of stock-based compensation expense, the valuation of impairment of long-lived assets, and the valuation allowance on deferred tax assets. On an ongoing basis, management reviews these estimates and assumptions. Impairment of long-lived assets In accordance with ASC 360-10, the Company records an impairment loss on long-lived assets used in operations when events and circumstances indicate that long-lived assets might be impaired and the undiscounted cash flows estimated to be generated by those assets are less than the carrying amounts of those assets (i.e. not able to be recovered). During the second quarter of Fiscal 2020, the Company announced the restructuring of its operations. This event required the reevaluation of the recoverability of the gross carrying value of its long-lived assets. Upon the Company’s announcement and at quarter-end, the Company performed an asset impairment analysis on its long-lived asset group, consisting of its property, plant and equipment, leases, and intangibles, which concluded that the carrying amount is not recoverable. However, the Company’s analysis indicated that carrying amount of the asset group does not exceed its fair value. As such, no impairment loss is required to be recognized. Nonetheless, it is reasonably possible that the impairment analysis may change in the near term resulting in the need to write down those assets to fair value. The Company will continue to monitor assets for impairment. Revenue recognition The Company has generated revenues from payments received from research service agreements, product sales, collaborative agreements with partners including pharmaceutical and biotechnology companies and academic institutions, licenses, and grants from the National Institutes of Health (“NIH”) and private not-for-profit organizations. The Company recognizes revenue under Topic 606, Revenue from Contracts with Customers (“Topic 606”) when (or as) the promised services are transferred to customers in an amount that reflects the consideration to which it expects to be entitled in exchange for those services. To determine revenue recognition for arrangements the Company concludes are within the scope of ASC 606, the Company performs the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligation(s) in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligation(s) in the contract; and (v) recognize revenue when (or as) the performance obligation(s) are satisfied. At contract inception, the Company assesses the goods or services promised within each contract, assesses whether each promised good or service is distinct and identifies those that are performance obligations. The Company recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied. 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 September 30, 2019 and March 31, 2019, the Company had approximately $0 and $525,000, respectively, in deferred revenue related to its research service agreements, collaborative agreements, and licenses within the scope of Topic 606. In the six months ended September 30, 2019, the Company recognized revenue on approximately $525,000, of which $490,000 related to the expiration of an agreement with a non-refundable up-front fee, that had been recorded as deferred revenue at March 31, 2019. Service revenues The Company’s service-based business, Organovo, Inc., utilized its NovoGen® bioprinting platform to provide customers access to its highly specialized tissues that model human biology and disease, and to in vitro testing services based on that technology. These contracts with customers contained multiple performance obligations including: (i) bioprinting tissues for the customer, (ii) reporting the results of tests performed on the printed tissues pursuant to the agreed upon work plan through exposure of the tissue to various factors (including the customer’s proprietary compound), and (iii) delivering specific byproduct study materials, which were satisfied, respectively, at each of the following points in time: (i) upon completion of manufacturing of the bioprinted tissue for the customer, (ii) upon delivery of the report on tests performed on the tissue, and (iii) upon making certain study materials generated from the aforementioned testing process available to the customer. The customer did not have access or control of any performance obligation prior to the point in time of full completion of the corresponding performance satisfying event as defined above. Furthermore, although the service could be customized for each customer, it was not so highly customized as to not have an alternative use either to other customers or to the Company without significant economic consequences or rework. Accordingly, the Company’s service-based business utilized point-in-time recognition under Topic 606. For service contracts, the Company allocated the transaction price to each performance obligation based on the estimated relative standalone selling prices of the promised products or services underlying each performance obligation. If the standalone selling price was not observable through past transactions, the Company estimated the standalone selling price taking into account available information such as market conditions and internally approved pricing guidelines related to the performance obligations. The transaction price for service business contracts was a fixed consideration. In connection to the Company’s decision to pursue its strategic alternatives, all commercial activities have been halted, except for product sales of primary human cells out of inventory. Product sales, net The Company’s product-based business, Samsara Sciences, Inc., produced high-quality cell-based products for use in Organovo’s 3D tissue manufacturing and for use by life science customers. The Company recognizes product revenue when the performance obligation is satisfied, which is at the point in time the customer obtains control of the Company’s product, typically upon delivery. Product revenues are recorded at the transaction price, net of any estimates for variable consideration under Topic 606. The Company’s process for estimating variable consideration does not differ materially from its historical practices. Variable consideration is estimated using the expected value method which considers the sum of probability-weighted amounts in a range of possible amounts under the contract. Product revenue reflects the Company’s best estimates of the amount of consideration to which it is entitled based on the terms of the individual contracts. Actual amounts of consideration ultimately received may differ from the Company’s estimates. If actual results vary materially from the Company’s estimates, the Company will adjust these estimates, which will affect revenue from product sales and earnings in the period such estimates are adjusted. The Company provides no right of return to its customers except in cases where a customer obtains authorization from the Company for the return. To date, there have been no product returns. The Company will continue to assess its estimates of variable consideration as it accumulates additional historical data and will adjust its estimates accordingly. Subsequent to the end of the quarter, on November 7, 2019, the Company entered into an agreement to sell substantially all of the Samsara inventory and associated assets for $1.5 million. As a result, the Company will have no further product sales beyond what it sold prior to the November 7th sale and will write-off the remainder of its inventory. Collaborative research, development, and licenses The Company has entered into collaborative agreements with partners that typically include one or more of the following: (i) non-exclusive license fees; (ii) non-refundable up-front fees; (iii) payments for reimbursement of research costs; (iv) payments associated with achieving specific development milestones; and (v) royalties based on specified percentages of net product sales, if any. At the initiation of an agreement, the Company has analyzed whether it results in a contract with a customer under Topic 606 or in an arrangement with a collaborator subject to guidance under ASC 808, Collaborative Arrangements (“Topic 808”). The Company has considered a variety of factors in determining the appropriate estimates and assumptions under these arrangements, such as whether the elements are distinct performance obligations, whether there are determinable stand-alone prices, and whether any licenses are functional or symbolic. The Company has evaluated each performance obligation to determine if it can be satisfied and recognized as revenue at a point in time or over time. Typically, non-exclusive license fees, non-refundable upfront fees, and funding of research activities have been considered fixed, while milestone payments have been identified as variable consideration which must be evaluated to determine if it has been constrained and, therefore, excluded from the transaction price. The Company’s collaborative agreements that were not completed at the implementation of Topic 606 on April 1, 2018, consisted of research collaboration and limited technology access licenses. These agreements provide the licensee with a non-exclusive, non-transferable, limited, royalty-free technology license, including access to Organovo’s proprietary bioprinter platform, training, and continued support by means of consumables and consultation throughout the duration of the contract. The Company has determined that the intellectual property license is not distinct from the continued support promised under the agreement and is therefore a single combined performance obligation. The Company recognized revenue for these combined performance obligations over time for the duration of the license period, as the combined performance obligation would not be fully satisfied until the end of the contract. For the six months ended September 30, 2019, all collaborations and licenses revenue was within the scope of Topic 606 and recognized accordingly. As of September 30, 2019, the Company completed its obligations under the existing agreements and does not anticipate recording any further revenue. See “Note 4. Collaborative Research, Development, and License Agreements” for more information on the Company’s collaborative agreements. Grant revenue In July 2017, the NIH awarded the Company a “Research and Development” grant totaling approximately $1,657,000 of funding over three years. The Company has concluded this government grant is not within the scope of Topic 606, as government entities do not meet the definition of a “customer” as defined by Topic 606, as there is not considered to be a transfer of control of goods or services to the government entity funding the grant. Additionally, the Company has concluded this government grant does meet the definition of a contribution and is a non-reciprocal transaction, however, Subtopic 958-605, Not-for-Profit-Entities-Revenue Recognition does not apply, as the Company is a business entity and the grant is with a governmental agency. Revenues from this grant have been based upon internal costs incurred that are specifically covered by the grant, plus an additional rate that provides funding for overhead expenses. Revenue has been recognized as the Company incurs expenses that are related to the grant. The Company believes this policy is consistent with the overarching premise in Topic 606, to ensure that it recognizes revenues to reflect the transfer of promised goods or services to customers in an amount that reflects the consideration to which it expects to be entitled in exchange for those goods or services, even though there is no “exchange” as defined in the ASC. The Company believes the recognition of revenue as costs are incurred and amounts become earned/realizable is analogous to the concept of transfer of control of a service over time under Topic 606. As of September 30, 2019, the Company has recognized approximately $1.2 million in grant revenue. Revenue recognized under this grant was approximately $0 and $52,000 for the three and six months ended September 30, 2019, respectively. Revenue recognized under this grant was approximately $408,000 and $508,000 for the three and six months ended September 30, 2018, respectively. In connection to the Company’s decision to pursue its strategic alternatives, all grant-related research activities have been halted, leaving a remaining balance of approximately $0.5 million in grant revenue that will not be recognized. Cost of revenues The Company reported approximately $0.3 million in cost of revenues for the three and six months ended September 30, 2019, which includes an inventory write-off of approximately $0.2 million consisting of raw materials related to the Company’s bioprinting and testing services and is a result of the Company’s decision to pursue its strategic alternatives. The Company reported approximately $0.1 million and $0.2 million in cost of revenues for the three and six months ended September 30, 2018, respectively. Cost of revenues consists of costs related to manufacturing and delivering product and service revenue.
Net loss per share Basic and diluted net loss per share has been computed using the weighted-average number of shares of common stock outstanding during the period. The weighted-average number of shares used to compute diluted loss per share excludes any assumed exercise of stock options and warrants, shares reserved for purchase under the Company’s 2016 Employee Stock Purchase Plan (“ESPP”), the assumed release of restriction of restricted stock units, and shares subject to repurchase as the effect would be anti-dilutive. No dilutive effect was calculated for the three and six months ended September 30, 2019 or 2018, as the Company reported a net loss for each respective period and the effect would have been anti-dilutive. Common stock equivalents excluded from computing diluted net loss per share were approximately 19.5 million at September 30, 2019 and 17.8 million at September 30, 2018. Recent Accounting Pronouncements From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board (“FASB”) or other standard setting bodies. Unless otherwise stated, the Company believes that the impact of the recently issued accounting pronouncements that are not yet effective will not have a material impact on its consolidated financial position or results of operations upon adoption. Adoption of New Accounting Pronouncements In February 2016, the FASB issued Accounting Standards Update (“ASU”) 2016-02, Leases (“ASC 842”), which supersedes the lease guidance under ASC 840 – Leases. The new accounting standard requires an entity to recognize right-of-use assets and corresponding lease liabilities on the balance sheet for all leases with terms of more than 12 months and to disclose key information about leasing arrangements. This new guidance became effective for the Company on April 1, 2019. The Company adopted ASC 842 on April 1, 2019 and elected the optional transition method that allows for a cumulative-effect adjustment in the period of adoption and did not require restatement of prior periods. The Company elected the package of practical expedients permitted under the transition guidance, but not the hindsight practical expedient. Please refer to “Note 6. Leases” for more information regarding the Company’s adoption of the new lease standard. In February 2018, the FASB issued ASU No. 2018-02, Income Statement – Reporting Comprehensive Income (“Topic 220”), which allows stranded tax effects resulting from the Tax Cuts and Jobs Act to be reclassified from accumulated other comprehensive income to retained earnings. The amendment only relates to the reclassification of the income tax effects of the Tax Cuts and Jobs Act; thus, the underlying guidance relating to the effect of a change in tax laws be included in income from continuing operations is not affected. The amendments in Topic 220 are effective for all entities for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. This new guidance became effective for the Company on April 1, 2019. The requirements of ASU 2018-02 did not have a significant impact on the Company’s financial statements. In June 2018, the FASB issued ASU No. 2018-07, Compensation - Stock Compensation: Improvements to Nonemployee Share-Based Payment Accounting, which aligns the measurement and classification guidance for share-based payment to non-employees with the guidance for share-based payments to employees. Under the new guidance, the measurement period for equity-classified non-employee awards will be fixed at the grant date. This new guidance became effective for the Company on April 1, 2019. The requirements of ASU 2018-07 did not have a significant impact on the Company’s financial statements. Recent Accounting Pronouncements Not Yet Adopted In November 2018, the FASB issued ASU 2018-18, Collaborative Arrangements (Topic 808): Clarifying the Interaction between Topic 808 and Topic 606, which provides guidance on whether certain transactions between collaborative arrangement participants should be accounted for as revenue under Topic 606. The amendments in this update provide more comparability in the presentation of revenue for certain transactions between collaborative arrangement participants. The key improvements to GAAP for collaborative arrangements resulting from this amendment are to (i) clarify that certain transactions between collaborative arrangement participants should be accounted for as revenue under Topic 606 when the collaborative arrangement participant is a customer in the context of a unit-of-account, (ii) add unit-of-account guidance in Topic 808 to align with the guidance in Topic 606, and (iii) require that in a transaction with a collaborative arrangement participant that is not directly related to sales to third parties, presenting the transaction together with revenue recognized under Topic 606 is precluded if the collaborative arrangement participant is not a customer. The amendments in this ASU are effective for all entities for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years with early adoption permitted. This new guidance is effective for us on April 1, 2020. The Company is currently evaluating the impact that this guidance will have on its financial statements. |

Note 3. Stockholders’ Equity Stock-based compensation expense and valuation information Stock-based awards include stock options and restricted stock units under the 2012 Equity Incentive Plan, as amended (“2012 Plan”) and Inducement Awards, performance-based restricted stock units under an Incentive Award Performance-Based Restricted Stock Unit Agreement, and rights to purchase stock under the 2016 Employee Stock Purchase Plan (“ESPP”). The Company calculates the grant date fair value of all stock-based awards in determining the stock-based compensation expense. Stock-based compensation expense for all stock-based awards consists of the following (in thousands):
The total unrecognized compensation cost related to unvested stock option grants as of September 30, 2019 was approximately $5,586,000 and the weighted average period over which these grants are expected to vest is 2.34 years. The total unrecognized compensation cost related to unvested restricted stock units (not including performance-based restricted stock units) as of September 30, 2019 was approximately $2,116,000, which will be recognized over a weighted average period of 2.21 years. The total unrecognized compensation cost related to unvested performance-based restricted stock units as of September 30, 2019 was approximately $2,720,000, which will be recognized over a weighted average period of 1.85 years. As of September 30, 2019, there are no participants enrolled into the employee stock purchase plan for the current purchase period, beginning September 1, 2019. The Company uses the Black-Scholes valuation model to calculate the fair value of stock options. Stock-based compensation expense is recognized over the vesting period using the straight-line method. The fair value of stock options was estimated at the grant date using the following weighted average assumptions:
The assumed dividend yield was based on the Company’s expectation of not paying dividends in the foreseeable future. Prior to fiscal year 2020, the Company used a blend of historical volatility and implied volatility of comparable companies. As of April 1, 2019, the Company is using the Company-specific historical volatility rate as it is more reflective of market conditions and a better indicator of expected volatility. The risk-free interest rate assumption was based on U.S. Treasury rates. The weighted average expected life of options was estimated using the average of the contractual term and the weighted average vesting term of the options. Prior to fiscal year 2020, certain options granted to consultants were subject to variable accounting treatment and were required to be revalued until vested. As of April 1, 2019, the measurement and classification of share-based payment to non-employees is consistent with the measurement and classification of share-based payment to employees.
The fair value of each restricted stock unit and performance-based restricted stock unit is recognized as stock-based compensation expense over the vesting term of the award. The fair value is based on the closing stock price on the date of the grant. The Company uses the Black-Scholes valuation model to calculate the fair value of shares issued pursuant to the Company’s ESPP. Stock-based compensation expense is recognized over the purchase period using the straight-line method. The fair value of ESPP shares was estimated at the purchase period commencement date using the following assumptions:
*There are no participants in the ESPP for the current purchase period (beginning September 1, 2019).
The assumed dividend yield was based on the Company’s expectation of not paying dividends in the foreseeable future. The Company uses the Company-specific historical volatility rate as the indicator of expected volatility. The risk-free interest rate assumption was based on U.S. Treasury rates. The expected life is the 6-month purchase period. Preferred stock The Company is authorized to issue 25,000,000 shares of preferred stock. There are no shares of preferred stock currently outstanding, and the Company has no current plans to issue shares of preferred stock. Common stock On June 25, 2019, the Company received a notice letter from the Listing Qualifications Staff of the Nasdaq Stock Market LLC (“Nasdaq”) indicating that, based upon the closing bid price of the Company’s common stock for the last 30 consecutive business days, the Company no longer meets the requirement to maintain a minimum closing bid price of $1 per share, as set forth in Nasdaq Listing Rule 5450(a)(1). In accordance with Nasdaq Listing Rule 5810(c)(3)(A), Nasdaq will provide the Company with a period of 180 calendar days, or until December 23, 2019, in which to regain compliance. In order to regain compliance with the minimum bid price requirement, the closing bid price of the Company’s common stock must be at least $1 per share for a minimum of ten consecutive business days during this 180-day period. In the event that the Company does not regain compliance within this 180-day period, the Company may be eligible to seek an additional compliance period of 180 calendar days if it elects to transfer to The Nasdaq Capital Market to take advantage of the additional compliance period offered on that market. To qualify, the Company would be required to meet the continued listing requirement for market value of publicly held shares and all other initial listing standards for The Nasdaq Capital Market, with the exception of the bid price requirement, and would need to provide written notice of its intention to cure the bid price deficiency during the second compliance period. The Company’s failure to regain compliance during this second compliance period could result in delisting. The June 25, 2019 Notice does not result in the immediate delisting of the Company’s common stock from the Nasdaq Global Market. The Company will continue to monitor the closing bid price of its common stock over the 180-day period to see if its closing bid price may increase based on its future filings with the Securities and Exchange Commission or any future announcements the Company may be able to issue regarding its business. The Company will also consider its available options to regain compliance, including effecting a reverse stock split, which would be subject to the prior approval of the Company’s stockholders. There can be no assurance that the Company will be able to regain compliance with the minimum bid price requirement or maintain compliance with the other listing requirements necessary for the Company to maintain the listing of its common stock on the Nasdaq Global Market. The Company has an effective shelf registration statement on Form S-3 (File No. 333-222929) and the related prospectus previously declared effective by the Securities and Exchange Commission (the “SEC”) on February 22, 2018 (the “2018 Shelf”), that expires on February 22, 2021, which registered $100,000,000 of common stock, preferred stock, warrants and units, or any combination of the foregoing. On March 16, 2018, the Company entered into a Sales Agreement (“2018 Sales Agreement”) with H.C. Wainwright & Co., LLC and Jones Trading Institutional Services LLC (each an “Agent” and together, the “Agents”) and filed a prospectus supplement to the 2018 Shelf, pursuant to which the Company may offer and sell, from time to time through the Agents, shares of its common stock in “at the market” sales transactions having an aggregate offering price of up to $50,000,000 (the “Shares”). Any shares offered and sold will be issued pursuant to the Company’s 2018 Shelf. During the three and six months ended September 30, 2019, the Company issued 0 and 6,087,382 shares of common stock, respectively, for net proceeds of $0 and $5.0 million in at-the-market offerings under the 2018 Sales Agreement. During the three and six months ended September 30, 2018, the Company issued 1,676,590 and 3,762,130 shares of common stock, respectively, for net proceeds of approximately $2.1 million and $5.1 million under the 2018 Sales Agreement. As of September 30, 2019, the Company has sold an aggregate of 17,719,185 shares of common stock in at-the-market offerings under the 2018 Sales Agreement, with gross proceeds of approximately $18.7 million. Based on these sales, the Company cannot raise more than an aggregate of $81.3 million in future offerings under the 2018 Shelf, including the $31.3 million remaining available for future issuance through its at-the-market program under the 2018 Sales Agreement. The Company intends to use the net proceeds raised through any at-the-market sales for general corporate purposes, general administrative expenses, and working capital and capital expenditures. On July 26, 2018, the Company filed an amendment to its certificate of incorporation to increase the number of authorized shares of common stock to 200,000,000 shares. Restricted stock units A summary of the Company’s restricted stock unit (not including performance-based restricted stock units) activity from March 31, 2019 through September 30, 2019 is as follows:
Performance-based restricted stock units On April 24, 2017, the Company issued a Performance-Based Restricted Stock Unit Award for 208,822 shares of common stock (the “PBRSU”) to its newly hired Chief Executive Officer. The PBRSU was issued outside of the 2012 Plan, in the Inducement Award Agreement, as an “inducement award” within the meaning of Nasdaq Marketplace Rule 5635(c)(4). While outside the Company’s 2012 Plan, the terms and conditions of these awards are consistent with awards granted to the Company’s executive officers pursuant to the 2012 Plan. On August 23, 2017, the Board of Directors formally approved the vesting criteria for the PBRSU. The vesting of the PBRSU is divided into five separate tranches each with independent vesting criteria. The first four tranches had performance criteria related to annual revenue goals with measurement at the end of fiscal year 2018 (20 percent), fiscal year 2019 (20 percent), fiscal year 2020 (20 percent), and fiscal year 2021 (20 percent). The fifth tranche had a performance metric related to a path to profitability goal measured as Negative Adjusted Earnings Before Interest, Taxes, Depreciation and Amortization (“EBITDA”) achievable at any point between the grant date and the end of fiscal year 2020 (20 percent). The number of units that ultimately vest for each tranche will range from 0 percent to 120 percent of the target amount, not to exceed 208,822 in aggregate. Based on changes to the Company’s strategy, on December 12, 2018, the Board of Directors formally approved an amendment to the vesting criteria for the PBRSUs. As of December 12, 2018, 100% of the Negative Adjusted EBITDA tranche, or 41,764 shares had vested and 8,352 units had been forfeited. Based on the amendment to the vesting criteria, the remaining 158,706 units eligible to vest upon future performance were divided into three separate but equal tranches with independent vesting criteria based on the achievement of certain regulatory milestones. As of September 30, 2019, no tranches are expected to vest unless there is a change in control. Based on the amended PBRSU vesting terms, which the Company believes are probable of being achieved, a Type III modification, the modified grant date fair value of the PBRSUs is $165,000 of which one-third is being recognized over the expected service period of each tranche ending on April 23, 2023. The Company began recording stock-based compensation expense for the initial performance tranches after the August 23, 2017 grant date when the initial financial performance goals were established and approved and has modified its recording of compensation expense in accordance with the amended performance tranches beginning on December 12, 2018. On July 2, 2019, the Company issued Performance-Based Restricted Stock Unit Awards (the “PBRSU Retention Awards”) for an aggregate of 6,027,899 shares of common stock to its management team. The PBRSUs were issued pursuant to the 2012 Plan. The PBRSU Retention Awards will vest in full upon the earlier of the Company’s engagement in a pre-IND meeting with the FDA, twenty-four months from the grant date, or a change in control. As of September 30, 2019, all PBRSUs are expected to vest twenty-four months from the grant date. A summary of the Company’s performance-based restricted stock unit activity from March 31, 2019 through September 30, 2019 is as follows:
Stock options A summary of the Company’s stock option activity from March 31, 2019 to September 30, 2019 is as follows:
The weighted average remaining contractual term of options exercisable and outstanding at September 30, 2019 was approximately 6.10 years. Employee Stock Purchase Plan In June 2016, our Board of Directors adopted, and in August 2016 stockholders subsequently approved, the 2016 Employee Stock Purchase Plan (“ESPP”). The Company reserved 1,500,000 shares of common stock for issuance thereunder. The ESPP permits employees after five months of service to purchase common stock through payroll deductions, limited to 15 percent of each employee’s compensation up to $25,000 per employee per year or 10,000 shares per employee per six-month purchase period. Shares under the ESPP are purchased at 85 percent of the fair market value at the lower of (i) the closing price on the first trading day of the six-month purchase period or (ii) the closing price on the last trading day of the six-month purchase period. The initial offering period commenced in September 2016. At September 30, 2019, there were 1,188,718 shares available for purchase under the ESPP. Warrants The following table summarizes warrant activity for the six months ended September 30, 2019:
The warrants outstanding at September 30, 2019 are exercisable at a price of $6.84 per share and have a weighted average remaining term of approximately 0.10 years. Common stock reserved for future issuance Common stock reserved for future issuance consisted of the following at September 30, 2019:

| Commitments And Contingencies Disclosure [Abstract] | |
| Commitments and Contingencies |
Note 5. Commitments and Contingencies Legal matters In addition to commitments and obligations in the ordinary course of business, the Company may be subject, from time to time, to various claims and pending and potential legal actions arising out of the normal conduct of its business. On October 10, 2019, a putative class action lawsuit was filed in the U.S. District Court for the District of Delaware against the Company and its board of directors in connection with the annual proxy statement filed by the Company on July 26, 2019. The case is captioned Rianhard v. Crouch., et al., Case No. 19-cv-1922 (D. Del. Oct. 10, 2019) (the “Action”). The complaint alleges that the Schedule 14A proxy statement contained material misrepresentations in connection with the reverse stock split proposal recommended therein and asserts claims for violations of Section 14(a) of the Securities Exchange Act of 1934 and Rule 14a-9 promulgated thereunder, as well as claims for breach of fiduciary duty. The Company believes the claims are without merit and intends to defend itself vigorously. The Company assesses contingencies to determine the degree of probability and range of possible loss for potential accrual in its financial statements. Because litigation is inherently unpredictable and unfavorable resolutions could occur, assessing litigation contingencies is subjective and requires judgments about future events. When evaluating contingencies, the Company may be unable to provide a meaningful estimate due to a number of factors, including the procedural status of the matter in question, the presence of complex or novel legal theories, and/or the ongoing discovery and development of information important to the matters. In addition, damage amounts claimed in litigation against it may be unsupported, exaggerated or unrelated to possible outcomes, and as such are not meaningful indicators of its potential liability. The Company regularly reviews contingencies to determine the adequacy of its accruals and related disclosures. During the period presented, the Company has not recorded any accrual for loss contingencies associated with the Action or any other such claims or legal proceedings; determined that an unfavorable outcome is probable or reasonably possible; or determined that the amount or range of any possible loss is reasonably estimable. However, the outcome of legal proceedings and claims brought against the Company is subject to significant uncertainty. Therefore, although management considers the likelihood of such an outcome to be remote, if the Action or one or more of these legal matters were resolved against the Company in a reporting period, the Company’s consolidated financial statements for that reporting period could be materially adversely affected. |

| Leases |
Note 6. Leases Adoption of ASC 842 As of April 1, 2019, the Company adopted ASC 842, which requires lessees to recognize a right-of-use asset (ROU asset) and lease liability for leases with terms of greater than twelve months. ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. The Company implemented this new accounting standard using the modified retrospective method for its existing leases, which did not cause any adjustments to prior year financial statements. The Company elected the package of practical expedients available for existing contracts, which allowed it to carry forward its historical assessments of whether contracts are or contain leases and the classification of its existing operating leases. Additionally, the Company elected the practical expedient to treat lease and non-lease components as a single lease component. The Company leases property and equipment under operating leases, specifically its office building and various copier machines. The Company also has a short-term lease (lease term is less than 12 months), which is not required to be recorded on the balance sheet under ASC 842. Instead, under ASC 842, the Company has elected the accounting policy for short term leases to recognize lease payments as an expense on a straight-line basis over the lease term. Upon adoption of ASC 842, the Company recognized ROU assets and corresponding lease liabilities based on the present value of remaining lease payments over the lease terms. ROU assets were measured as lease liabilities plus prepaid rent less any deferred rent. As interest rates were not implicitly stated in the respective lease agreements, nor were they readily determinable, the Company used its incremental borrowing rate as the discount rate when measuring lease liabilities. Upon adoption of ASC 842, the Company recorded ROU assets and lease liabilities of $4.5 million and $5.0 million, respectively. The Company also classified deferred rent of $0.6 million as an offset to the Company’s ROU asset upon adoption. The impact of the adoption of ASC 842 on the consolidated balance sheet as of April 1, 2019 is as follows (in thousands):
After the initial adoption of ASC 842, on an on-going basis, the Company evaluates all contracts upon inception and determines whether the contract contains a lease by assessing whether there is an identified asset and whether the contract conveys the right to control the use of identified asset in exchange for consideration over a period of time. If a lease is identified, the Company will apply the guidance from ASC 842 to properly account for the lease. Operating Leases Since July 2012, the Company has leased its main facilities at 6275 Nancy Ridge Drive, San Diego, California 92121. The lease, as amended in 2013, 2015, 2016, 2018, and 2019, consisted of approximately 45,580 rentable square feet containing laboratory, clean room and office space. Monthly rental payments are approximately $87,000 with 3% annual escalators. The lease for 14,685 of the total rentable square footage was amended to accelerate the expiration date from December 15, 2018 to October 31, 2018. On November 30, 2018, the Company agreed to extend the term for the remainder of the total rentable square footage under the lease from August 31, 2021 to August 31, 2024 in exchange for $500,000 of landlord funded tenant improvements and a rescission of its option to terminate the lease on or after September 1, 2019 with 9 months prior written notice. In addition to the Company’s main facility lease, on March 21, 2019, the Company entered into an agreement to lease several copy machines for a term of 36 months. The lease contains fixed monthly payments through the entire term of the lease, and it does not contain an option to extend the term or a bargain purchase option. This lease was also carried forward as an operating lease through the adoption of Topic 842. The table below summarizes the Company’s lease liabilities and corresponding right-of-use assets as of September 30, 2019 (in thousands):
The Company records operating lease expense on a straight-line basis over the life of the leases. This is consistent with the Company’s historical treatment of the lease costs included in operating expenses (referred to as “Rent Expense” prior to adoption of Topic 842). For the three and six months ended September 30, 2019, the Company recorded operating lease expense of approximately $262,000 and $524,000, respectively. For the three and six months ended September 30, 2018, the Company recorded rent expense of approximately $326,000 and $651,000, respectively. Variable lease costs associated with the Company’s leases, such as payments for additional monthly fees to cover the Company’s share of certain facility expenses (common area maintenance, or CAM) are not included in operating lease right-of use assets and lease liabilities, but rather expensed as incurred. Variable lease expense was approximately $130,000 and $237,000 for the three and six months ended September 30, 2019, respectively. Short-term lease cost for the three and six months ended September 30, 2019 was approximately $22,000 and $37,000, respectively. As of September 30, 2019, the short-term lease was terminated. The table below is a summary of the cash flows associated with the Company’s leases for the three months ended September 30, 2019 (in thousands):
Future lease payments relating to the Company’s operating lease liabilities as of September 30, 2019, are as follows (in thousands):

| Concentrations |
Note 7. 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 within the United States. Accounts at these institutions are secured by the Federal Deposit Insurance Corporation. 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. The Company is also potentially subject to concentrations of credit risk in its revenues and accounts receivable. Because it is in the early commercial stage, the Company’s revenues to date have been derived from a relatively small number of customers and collaborators. However, the Company has not historically experienced any accounts receivable write-downs and management does not believe significant credit risk exists as of September 30, 2019. |

Note 8. Related Parties From time to time, the Company will enter into an agreement with a related party in the ordinary course of its business and on terms and conditions it believes are as fair as those it offers and receives from independent third parties. These agreements are ratified by the Company’s Board of Directors or a committee thereof pursuant to its related party transaction policy. In August 2017, the Company entered into a research services agreement with Cirius Therapeutics, Inc. (“Cirius”), an entity for which Robert Baltera, Jr., a former director of the Company, serves as Chief Executive Officer and President. Under this agreement, the Company is providing standard research services to Cirius utilizing its ExVive™ Liver Tissue platform. The Company has provided and recognized revenue for ExVive™ Liver Tissue Services for Cirius in the amount of $281,000 to date. Organovo completed its obligations as of December 2018. No further revenues are expected. In November 2018, the Company entered into a research services Quote with Viscient Biosciences (“Viscient”), an entity for which Keith Murphy, the Company’s former director, Chief Executive Officer, and President, serves as the Chief Executive Officer and President. Under this Quote, the Company is providing research services in the amount of $142,000, amended in April 2019 to include an additional $7,000 of services. As of March 31, 2019, the Company recognized revenue of $42,000 for services provided and the remaining amount of $107,000 was recognized as revenue in the six months ended September 30, 2019. In addition to the services provided by Organovo, Viscient has purchased primary human cell-based products from our subsidiary, Samsara. Pursuant to the terms of multiple Quotes, $71,000 and $83,000 was recognized as revenue in the three and six months ended September 30, 2019, respectively. Pursuant to the terms of multiple Quotes, $1,000 and $3,000 was recognized as revenue in the three and six months ended September 30, 2018, respectively. Subsequent to September 30, 2019, Viscient executed additional Quotes to purchase primary human cell-based products from Samsara in the amount of $44,000, which will be recognized in the third quarter of Fiscal 2020. |

| Restructuring |
Note 9. Restructuring In August 2019, after a rigorous assessment of the Company’s lead liver therapeutic tissue program following completion of various preclinical studies, the Company’s Board of Directors (the “Board”) concluded that the variability of biological performance and related duration of potential benefits presented development challenges and lengthy redevelopment timelines that no longer supported an attractive opportunity for the Company and its stockholders. Furthermore, the Board deemed the stage of development of the Company’s other therapeutic pipeline assets, including stem cell based tissue programs, to be too premature to potentially reach IND filing status within an acceptable investment horizon and with the Company’s available resources. As a result, the Company suspended all development of its lead program and all other related pipeline development activity and engaged a financial advisory firm to explore its strategic alternatives, including evaluating a range of ways to generate value from the Company’s technology platform and intellectual property, its commercial and development capabilities, its listing on the Nasdaq Stock Market, and its remaining financial assets. Under the restructuring plan, the Company terminated the employment of 46 employees, or 79% of its workforce and recorded a restructuring charge in the fiscal second quarter of approximately $2.5 million, primarily related to employee severance and benefits costs, of which $1.7 million was paid out during the fiscal second quarter and the remainder is anticipated to be paid out during the fiscal third quarter. The Company currently expects further restructuring actions tied to progress made on the strategic alternatives process, which could lead to an additional $3.1 million of severance and benefits costs that would be incurred and paid on or prior to a possible strategic transaction, of which $0.4 million is expected to be incurred during the Company’s fiscal third quarter, with the remainder to be incurred upon closing of a strategic transaction. Restructuring charges were recorded in selling, general and administrative expenses and were comprised of the following (in thousands):

| Subsequent Events |
Note 10. Subsequent Events On October 2, 2019, the Company entered into an agreement to rent office space at 440 Stevens Avenue, Suite 200, Solana Beach, California 92075. This agreement is a month-to-month contract and can be terminated at-will by either party at any time. As such, the Company has concluded that this agreement does not contain a lease and will be expensed as incurred. Monthly rental payments are approximately $4,000 per month. On October 9, 2019, the Company entered into an agreement to assume its leased copy machines, which terminates future obligations. As such, the Company will write-off its associated right-of-use asset of approximately $26,000 and lease liabilities of approximately $26,000 in the third quarter of Fiscal 2020.
On October 11, 2019, the Company entered into an agreement to accelerate the expiration date of the term of the lease for its main facilities on 6275 Nancy Ridge Drive from August 31, 2024 to November 15, 2019. Under this agreement, the Landlord and Tenant agree that the other is excused as of the termination date from any further obligations. As such, the Company will write-off its associated right-of-use asset of approximately $4.1 million and lease liabilities of approximately $4.6 million in the third quarter of Fiscal 2020. In accordance with ASC 842-20-35-12, the Company will update the useful lives of its leasehold improvement assets to the accelerated termination date. The impact of the ROU asset write-off, lease liability write-off, and retirement of leasehold improvements will be approximately $0.2 million of depreciation expense in the third quarter of Fiscal 2020. On November 6, 2019, the Company entered into an agreement to sell certain bioprinting equipment and a non-exclusive license to certain intellectual property to Viscient, a related party, for approximately $0.2 million. On November 7, 2019, the Company entered into an agreement to sell certain inventory and equipment and related proprietary information of its Samsara Sciences, Inc. subsidiary for $1.5 million. As a result, Samsara Sciences, Inc. will have no further product sales after the November 7th sale date. |

| Accounting Policies [Abstract] | |
| Basis of presentation and principles of consolidation |
Basis of presentation and principles of consolidation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not necessarily include all information and notes required by GAAP for complete financial statements. The condensed consolidated balance sheet at March 31, 2019 is derived from the Company’s audited consolidated balance sheet at that date. The unaudited condensed consolidated financial statements include the accounts of Organovo Holdings and its wholly owned subsidiaries. All material intercompany accounts and transactions have been eliminated in consolidation. 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 the Company’s financial position, results of operations, stockholders’ equity and cash flows. These unaudited condensed consolidated financial statements should be read in conjunction with the audited financial statements and notes included in the Company’s Annual Report on Form 10-K for the year ended March 31, 2019, as filed with the Securities and Exchange Commission (“SEC”). Operating results for interim periods are not necessarily indicative of operating results for the Company’s fiscal year ending March 31, 2020 (see “Note 1. Description of Business”). |
| Liquidity |
Liquidity As of September 30, 2019, the Company had cash and cash equivalents of approximately $30.4 million and restricted cash of approximately $0.1 million. The restricted cash was pledged as collateral for a letter of credit that the Company is required to maintain as a security deposit under the terms of the lease of its facilities. The Company had an accumulated deficit of approximately $273.4 million at September 30, 2019. The Company also had negative cash flows from operations of approximately $11.1 million during the six months ended September 30, 2019. Through September 30, 2019, the Company has financed its operations primarily through the sale of convertible notes, warrants, the private placement of equity securities, the sale of common stock through public and at-the-market (“ATM”) offerings, and through revenue derived from product and research service-based agreements, collaborative agreements, licenses, and grants. During the three and six months ended September 30, 2019, the Company issued 0 and 6,087,382 shares of its common stock through its ATM facility and received net proceeds of approximately $0 and $5.0 million, respectively. As we explore various strategic alternatives, we have taken steps to manage our resources and extend our cash runway including halting all commercial activities except for sales of primary human cells out of inventory, negotiating an exit from our long-term facility lease, selling various assets, and reducing our workforce to the minimum level necessary to explore and support these strategic alternatives. As a result, the Company terminated the employment of 46 employees, or 79% of its workforce and recorded a restructuring charge in the fiscal second quarter of approximately $2.5 million, primarily related to employee severance and benefits costs, of which $1.7 million was paid out during the fiscal second quarter and the remainder is anticipated to be paid out during the fiscal third quarter. The Company currently expects further restructuring actions tied to progress made on the strategic alternatives process, which could lead to an additional $3.1 million of severance and benefits costs that would be incurred and paid on or prior to a possible strategic transaction, of which $0.4 million is expected to be incurred during the Company’s fiscal third quarter, with the remainder to be incurred upon closing of a strategic transaction. As a result, absent any further impact from asset sales or merger related costs or other costs incurred from other strategic alternatives, the Company expects its cash balance to be between $28.0 million and $29.0 million at the end of its fiscal third quarter and between $26.0 million and $27.0 million at the end of its fiscal fourth quarter. Although the Company is actively pursuing strategic alternatives, there is no assurance that it will be able to successfully negotiate and consummate one or more transactions on a timely basis, or at all. Further, the Company’s expenses may exceed its current plans and expectations, which could cause the Company to complete a transaction or wind-down its operations sooner than anticipated. Additionally, any transaction the Company consummates may offer limited value for the Company’s existing business and proprietary technology and may not enhance stockholder value or provide the expected benefits. If the Company is unable to successfully complete a strategic transaction or secure additional capital on a timely basis and on terms that are acceptable to its stockholders, the Company may elect to cease its operations altogether, in which event the value realized by our stockholders might be significantly less than the $31.1 million of stockholders’ equity recorded on our consolidated financial statements as of September 30, 2019. While the Company believes that it can maintain its current operations for at least the next 12 months, based on its current plans and available resources, the assessment by the Company discussed above with respect to its strategic alternatives raises substantial doubt over the Company’s ability to successfully finance itself on a long-term basis. The accompanying consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty. |
| Use of estimates |
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 consolidated financial statements include those assumed in revenue recognition, the measurement of operating lease right-of-use assets and lease liabilities, the valuation of stock-based compensation expense, the valuation of impairment of long-lived assets, and the valuation allowance on deferred tax assets. On an ongoing basis, management reviews these estimates and assumptions. Impairment of long-lived assets In accordance with ASC 360-10, the Company records an impairment loss on long-lived assets used in operations when events and circumstances indicate that long-lived assets might be impaired and the undiscounted cash flows estimated to be generated by those assets are less than the carrying amounts of those assets (i.e. not able to be recovered). During the second quarter of Fiscal 2020, the Company announced the restructuring of its operations. This event required the reevaluation of the recoverability of the gross carrying value of its long-lived assets. Upon the Company’s announcement and at quarter-end, the Company performed an asset impairment analysis on its long-lived asset group, consisting of its property, plant and equipment, leases, and intangibles, which concluded that the carrying amount is not recoverable. However, the Company’s analysis indicated that carrying amount of the asset group does not exceed its fair value. As such, no impairment loss is required to be recognized. Nonetheless, it is reasonably possible that the impairment analysis may change in the near term resulting in the need to write down those assets to fair value. The Company will continue to monitor assets for impairment. |
| Revenue recognition |
Revenue recognition The Company has generated revenues from payments received from research service agreements, product sales, collaborative agreements with partners including pharmaceutical and biotechnology companies and academic institutions, licenses, and grants from the National Institutes of Health (“NIH”) and private not-for-profit organizations. The Company recognizes revenue under Topic 606, Revenue from Contracts with Customers (“Topic 606”) when (or as) the promised services are transferred to customers in an amount that reflects the consideration to which it expects to be entitled in exchange for those services. To determine revenue recognition for arrangements the Company concludes are within the scope of ASC 606, the Company performs the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligation(s) in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligation(s) in the contract; and (v) recognize revenue when (or as) the performance obligation(s) are satisfied. At contract inception, the Company assesses the goods or services promised within each contract, assesses whether each promised good or service is distinct and identifies those that are performance obligations. The Company recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied. 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 September 30, 2019 and March 31, 2019, the Company had approximately $0 and $525,000, respectively, in deferred revenue related to its research service agreements, collaborative agreements, and licenses within the scope of Topic 606. In the six months ended September 30, 2019, the Company recognized revenue on approximately $525,000, of which $490,000 related to the expiration of an agreement with a non-refundable up-front fee, that had been recorded as deferred revenue at March 31, 2019. Service revenues The Company’s service-based business, Organovo, Inc., utilized its NovoGen® bioprinting platform to provide customers access to its highly specialized tissues that model human biology and disease, and to in vitro testing services based on that technology. These contracts with customers contained multiple performance obligations including: (i) bioprinting tissues for the customer, (ii) reporting the results of tests performed on the printed tissues pursuant to the agreed upon work plan through exposure of the tissue to various factors (including the customer’s proprietary compound), and (iii) delivering specific byproduct study materials, which were satisfied, respectively, at each of the following points in time: (i) upon completion of manufacturing of the bioprinted tissue for the customer, (ii) upon delivery of the report on tests performed on the tissue, and (iii) upon making certain study materials generated from the aforementioned testing process available to the customer. The customer did not have access or control of any performance obligation prior to the point in time of full completion of the corresponding performance satisfying event as defined above. Furthermore, although the service could be customized for each customer, it was not so highly customized as to not have an alternative use either to other customers or to the Company without significant economic consequences or rework. Accordingly, the Company’s service-based business utilized point-in-time recognition under Topic 606. For service contracts, the Company allocated the transaction price to each performance obligation based on the estimated relative standalone selling prices of the promised products or services underlying each performance obligation. If the standalone selling price was not observable through past transactions, the Company estimated the standalone selling price taking into account available information such as market conditions and internally approved pricing guidelines related to the performance obligations. The transaction price for service business contracts was a fixed consideration. In connection to the Company’s decision to pursue its strategic alternatives, all commercial activities have been halted, except for product sales of primary human cells out of inventory. Product sales, net The Company’s product-based business, Samsara Sciences, Inc., produced high-quality cell-based products for use in Organovo’s 3D tissue manufacturing and for use by life science customers. The Company recognizes product revenue when the performance obligation is satisfied, which is at the point in time the customer obtains control of the Company’s product, typically upon delivery. Product revenues are recorded at the transaction price, net of any estimates for variable consideration under Topic 606. The Company’s process for estimating variable consideration does not differ materially from its historical practices. Variable consideration is estimated using the expected value method which considers the sum of probability-weighted amounts in a range of possible amounts under the contract. Product revenue reflects the Company’s best estimates of the amount of consideration to which it is entitled based on the terms of the individual contracts. Actual amounts of consideration ultimately received may differ from the Company’s estimates. If actual results vary materially from the Company’s estimates, the Company will adjust these estimates, which will affect revenue from product sales and earnings in the period such estimates are adjusted. The Company provides no right of return to its customers except in cases where a customer obtains authorization from the Company for the return. To date, there have been no product returns. The Company will continue to assess its estimates of variable consideration as it accumulates additional historical data and will adjust its estimates accordingly. Subsequent to the end of the quarter, on November 7, 2019, the Company entered into an agreement to sell substantially all of the Samsara inventory and associated assets for $1.5 million. As a result, the Company will have no further product sales beyond what it sold prior to the November 7th sale and will write-off the remainder of its inventory. Collaborative research, development, and licenses The Company has entered into collaborative agreements with partners that typically include one or more of the following: (i) non-exclusive license fees; (ii) non-refundable up-front fees; (iii) payments for reimbursement of research costs; (iv) payments associated with achieving specific development milestones; and (v) royalties based on specified percentages of net product sales, if any. At the initiation of an agreement, the Company has analyzed whether it results in a contract with a customer under Topic 606 or in an arrangement with a collaborator subject to guidance under ASC 808, Collaborative Arrangements (“Topic 808”). The Company has considered a variety of factors in determining the appropriate estimates and assumptions under these arrangements, such as whether the elements are distinct performance obligations, whether there are determinable stand-alone prices, and whether any licenses are functional or symbolic. The Company has evaluated each performance obligation to determine if it can be satisfied and recognized as revenue at a point in time or over time. Typically, non-exclusive license fees, non-refundable upfront fees, and funding of research activities have been considered fixed, while milestone payments have been identified as variable consideration which must be evaluated to determine if it has been constrained and, therefore, excluded from the transaction price. The Company’s collaborative agreements that were not completed at the implementation of Topic 606 on April 1, 2018, consisted of research collaboration and limited technology access licenses. These agreements provide the licensee with a non-exclusive, non-transferable, limited, royalty-free technology license, including access to Organovo’s proprietary bioprinter platform, training, and continued support by means of consumables and consultation throughout the duration of the contract. The Company has determined that the intellectual property license is not distinct from the continued support promised under the agreement and is therefore a single combined performance obligation. The Company recognized revenue for these combined performance obligations over time for the duration of the license period, as the combined performance obligation would not be fully satisfied until the end of the contract. For the six months ended September 30, 2019, all collaborations and licenses revenue was within the scope of Topic 606 and recognized accordingly. As of September 30, 2019, the Company completed its obligations under the existing agreements and does not anticipate recording any further revenue. See “Note 4. Collaborative Research, Development, and License Agreements” for more information on the Company’s collaborative agreements. Grant revenue In July 2017, the NIH awarded the Company a “Research and Development” grant totaling approximately $1,657,000 of funding over three years. The Company has concluded this government grant is not within the scope of Topic 606, as government entities do not meet the definition of a “customer” as defined by Topic 606, as there is not considered to be a transfer of control of goods or services to the government entity funding the grant. Additionally, the Company has concluded this government grant does meet the definition of a contribution and is a non-reciprocal transaction, however, Subtopic 958-605, Not-for-Profit-Entities-Revenue Recognition does not apply, as the Company is a business entity and the grant is with a governmental agency. Revenues from this grant have been based upon internal costs incurred that are specifically covered by the grant, plus an additional rate that provides funding for overhead expenses. Revenue has been recognized as the Company incurs expenses that are related to the grant. The Company believes this policy is consistent with the overarching premise in Topic 606, to ensure that it recognizes revenues to reflect the transfer of promised goods or services to customers in an amount that reflects the consideration to which it expects to be entitled in exchange for those goods or services, even though there is no “exchange” as defined in the ASC. The Company believes the recognition of revenue as costs are incurred and amounts become earned/realizable is analogous to the concept of transfer of control of a service over time under Topic 606. As of September 30, 2019, the Company has recognized approximately $1.2 million in grant revenue. Revenue recognized under this grant was approximately $0 and $52,000 for the three and six months ended September 30, 2019, respectively. Revenue recognized under this grant was approximately $408,000 and $508,000 for the three and six months ended September 30, 2018, respectively. In connection to the Company’s decision to pursue its strategic alternatives, all grant-related research activities have been halted, leaving a remaining balance of approximately $0.5 million in grant revenue that will not be recognized. |
| Cost of revenues |
Cost of revenues The Company reported approximately $0.3 million in cost of revenues for the three and six months ended September 30, 2019, which includes an inventory write-off of approximately $0.2 million consisting of raw materials related to the Company’s bioprinting and testing services and is a result of the Company’s decision to pursue its strategic alternatives. The Company reported approximately $0.1 million and $0.2 million in cost of revenues for the three and six months ended September 30, 2018, respectively. Cost of revenues consists of costs related to manufacturing and delivering product and service revenue.
|
| Net loss per share |
Net loss per share Basic and diluted net loss per share has been computed using the weighted-average number of shares of common stock outstanding during the period. The weighted-average number of shares used to compute diluted loss per share excludes any assumed exercise of stock options and warrants, shares reserved for purchase under the Company’s 2016 Employee Stock Purchase Plan (“ESPP”), the assumed release of restriction of restricted stock units, and shares subject to repurchase as the effect would be anti-dilutive. No dilutive effect was calculated for the three and six months ended September 30, 2019 or 2018, as the Company reported a net loss for each respective period and the effect would have been anti-dilutive. Common stock equivalents excluded from computing diluted net loss per share were approximately 19.5 million at September 30, 2019 and 17.8 million at September 30, 2018. |
| Recent Accounting Pronouncements |
Recent Accounting Pronouncements From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board (“FASB”) or other standard setting bodies. Unless otherwise stated, the Company believes that the impact of the recently issued accounting pronouncements that are not yet effective will not have a material impact on its consolidated financial position or results of operations upon adoption. Adoption of New Accounting Pronouncements In February 2016, the FASB issued Accounting Standards Update (“ASU”) 2016-02, Leases (“ASC 842”), which supersedes the lease guidance under ASC 840 – Leases. The new accounting standard requires an entity to recognize right-of-use assets and corresponding lease liabilities on the balance sheet for all leases with terms of more than 12 months and to disclose key information about leasing arrangements. This new guidance became effective for the Company on April 1, 2019. The Company adopted ASC 842 on April 1, 2019 and elected the optional transition method that allows for a cumulative-effect adjustment in the period of adoption and did not require restatement of prior periods. The Company elected the package of practical expedients permitted under the transition guidance, but not the hindsight practical expedient. Please refer to “Note 6. Leases” for more information regarding the Company’s adoption of the new lease standard. In February 2018, the FASB issued ASU No. 2018-02, Income Statement – Reporting Comprehensive Income (“Topic 220”), which allows stranded tax effects resulting from the Tax Cuts and Jobs Act to be reclassified from accumulated other comprehensive income to retained earnings. The amendment only relates to the reclassification of the income tax effects of the Tax Cuts and Jobs Act; thus, the underlying guidance relating to the effect of a change in tax laws be included in income from continuing operations is not affected. The amendments in Topic 220 are effective for all entities for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. This new guidance became effective for the Company on April 1, 2019. The requirements of ASU 2018-02 did not have a significant impact on the Company’s financial statements. In June 2018, the FASB issued ASU No. 2018-07, Compensation - Stock Compensation: Improvements to Nonemployee Share-Based Payment Accounting, which aligns the measurement and classification guidance for share-based payment to non-employees with the guidance for share-based payments to employees. Under the new guidance, the measurement period for equity-classified non-employee awards will be fixed at the grant date. This new guidance became effective for the Company on April 1, 2019. The requirements of ASU 2018-07 did not have a significant impact on the Company’s financial statements. Recent Accounting Pronouncements Not Yet Adopted In November 2018, the FASB issued ASU 2018-18, Collaborative Arrangements (Topic 808): Clarifying the Interaction between Topic 808 and Topic 606, which provides guidance on whether certain transactions between collaborative arrangement participants should be accounted for as revenue under Topic 606. The amendments in this update provide more comparability in the presentation of revenue for certain transactions between collaborative arrangement participants. The key improvements to GAAP for collaborative arrangements resulting from this amendment are to (i) clarify that certain transactions between collaborative arrangement participants should be accounted for as revenue under Topic 606 when the collaborative arrangement participant is a customer in the context of a unit-of-account, (ii) add unit-of-account guidance in Topic 808 to align with the guidance in Topic 606, and (iii) require that in a transaction with a collaborative arrangement participant that is not directly related to sales to third parties, presenting the transaction together with revenue recognized under Topic 606 is precluded if the collaborative arrangement participant is not a customer. The amendments in this ASU are effective for all entities for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years with early adoption permitted. This new guidance is effective for us on April 1, 2020. The Company is currently evaluating the impact that this guidance will have on its financial statements. |

- Definition Tabular disclosure of warrants or rights issued. Warrants and rights outstanding are derivative securities that give the holder the right to purchase securities (usually equity) from the issuer at a specific price within a certain time frame. Warrants are often included in a new debt issue to entice investors by a higher return potential. The main difference between warrants and call options is that warrants are issued and guaranteed by the company, whereas options are exchange instruments and are not issued by the company. Also, the lifetime of a warrant is often measured in years, while the lifetime of a typical option is measured in months. Disclose the title of issue of securities called for by warrants and rights outstanding, the aggregate amount of securities called for by warrants and rights outstanding, the date from which the warrants or rights are exercisable, and the price at which the warrant or right is exercisable.
