Summary of Significant Accounting Policies | Note 2. Summary of Significant Accounting Policies Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) and Article 10 of Regulation S-X requirements as set forth by the Securities and Exchange Commission (“SEC”) for interim financial information and reflect all adjustments and disclosures, which are, in the opinion of management, of a normal and recurring nature, and considered necessary for a fair presentation of the financial information contained herein. Pursuant to these rules and regulations, the unaudited condensed consolidated financial statements do not include all information and notes necessary for a complete presentation of results of operations and comprehensive loss, financial position, and cash flows in conformity with GAAP. The accompanying unaudited condensed consolidated financial statements and notes should be read in conjunction with the audited financial statements and accompanying notes of Novus for the year ended December 31, 2019 included in the Annual Report on Form 10-K filed by the Company with the SEC on March 16, 2020. The results of operations and comprehensive loss for the three months ended March 31, 2020 are not necessarily indicative of results expected for the full fiscal year or any other future period. Principles of Consolidation Novus, a Delaware corporation, owns 100% of the issued and outstanding common stock or other ownership interest in Otic Pharma, Ltd., a private limited company organized under the laws of the State of Israel (“Otic”). Otic owns 100% of the issued and outstanding common stock or other ownership interest in its U.S. subsidiary, Otic Pharma, Inc. The functional currency of the Company’s foreign subsidiary is the U.S. Dollar; however, certain expenses, assets and liabilities are transacted at the local currency. These transactions are translated from the local currency into U.S. Dollars at exchange rates during or at the end of the reporting period. The activities of the Company’s foreign subsidiary are not significant to the condensed consolidated financial statements. All significant intercompany accounts and transactions among the entities have been eliminated from the condensed consolidated financial statements. Liquidity and Financial Condition The Company has experienced recurring net losses and negative cash flows from operating activities since its inception. The Company recorded a net loss of $8.2 million for the three months ended March 31, 2020. As of March 31, 2020, the Company had cash of $11.8 million, working capital of $11.0 million and an accumulated deficit of $65.8 million. Due to continuing research and development activities, the Company expects to continue to incur net losses into the foreseeable future. In order to continue these activities, the Company may need to raise additional funds through future public or private debt and equity financings or strategic collaboration and licensing arrangements. The Company’s ability to raise additional capital in the equity and debt markets is dependent on a number of factors, including, but not limited to, the market demand for the Company’s common stock, which itself is subject to a number of development and business risks and uncertainties, as well as the uncertainty that the Company would be able to raise such additional capital at a price or on terms that are favorable to the Company. If the Company issues equity or convertible debt securities to raise additional funding, its existing stockholders may experience dilution, it may incur significant financing costs, and the new equity or convertible debt securities may have rights, preferences and privileges senior to those of its existing stockholders. If the Company issues debt securities to raise additional funding, it would incur additional debt service obligations, it could become subject to additional restrictions limiting its ability to operate its business, and it may be required to further encumber its assets. Adequate additional funding may not be available to us on acceptable terms on a timely basis, or at all. During fiscal year 2019 and in the first three months of 2020, the Company has implemented, and will continue to implement, certain cost cutting measures to reduce its cash flow requirements. Consistent with the actions the Company has taken in the past, it will execute the appropriate steps to enable the continued operation of the business and preservation of the value of its assets beyond the next twelve months, including but not limited to actions such as reduced personnel-related costs, delay or curtailment of the Company’s research and development activities, and other discretionary expenses that are within the Company’s control. These initiatives, if required, may have an adverse impact on the Company’s ability to achieve certain of its planned objectives as it seeks strategic alternatives. On August 8, 2019, the Company received written notice (the “Notification Letter”) from The Nasdaq Stock Market LLC (“Nasdaq”) notifying the Company that it was not in compliance with the minimum bid price requirements set forth in Nasdaq Listing Rule 5550(a)(2) for continued listing on The Nasdaq Capital Market. Nasdaq Listing Rule 5550(a)(2) requires listed securities maintain a minimum closing bid price of $1.00 per share, and Nasdaq Listing Rule 5810(c)(3)(A) provides that a failure to meet the minimum closing bid price requirement exists if the deficiency continues for a period of 30 consecutive business days. Based on the closing bid price of the Company’s common stock for the 30 consecutive business days prior to the date of the Notification Letter, the Company did not meet the minimum closing bid price requirement. The Notification Letter stated that the Company had 180 calendar days, or until February 4, 2020, to regain compliance with Nasdaq Listing Rule 5550(a)(2). On February 6, 2020, the Company received written notice that Nasdaq determined that it is eligible for an additional 180-day extension (the “Extension Letter”), or until August 3, 2020, to regain compliance with the minimum bid price requirement. The Extension Letter does not impact the Company’s listing on the Nasdaq Capital Market at this time. To regain compliance, the closing bid price of the Company’s common stock must be at least $1.00 per share for a minimum of 10 consecutive business days at any time prior to August 3, 2020 On April 21, 2020, the Company received an additional notice from Nasdaq (the “Tolling Notice”), which stated that, due to current market conditions, Nasdaq has determined to toll the compliance period for the minimum bid price requirement through June 30, 2020. As a result, the new date by which the Company has to regain compliance with the minimum bid price requirement is October 19, 2020. The Company intends to monitor the closing bid price of its common stock and consider its available options to resolve its noncompliance with the minimum bid price requirement. There can be no assurance that the Company will be able to regain compliance with the minimum bid price requirement or that the Company will otherwise be in compliance with other Nasdaq listing criteria. If the Company fails to regain compliance with the minimum bid requirement or to meet the other applicable continued listing requirements for the Nasdaq Capital Market in the future and Nasdaq determines to delist its common stock, the delisting could adversely affect the market price and liquidity of the Company’s common stock and reduce its ability to raise additional capital. If the Company’s common stock is delisted by Nasdaq, the common stock may be eligible to trade on the OTC Bulletin Board or another market. Any such alternative would likely result in it being more difficult for the Company to raise additional capital through the public or private sale of equity securities and for investors to dispose of, or obtain accurate quotations as to the market value of, the common stock and could result in a decrease in the trading price of our common stock. In addition, there can be no assurance that the common stock would be eligible for trading on any such alternative exchange or markets. At the time of issuance of the condensed consolidated financial statements for the period ended March 31, 2020, the Company concluded that there is substantial doubt regarding the Company’s ability to continue as a going concern for the twelve months from the date of filing of this quarterly report on Form 10-Q. The financial information and the condensed consolidated financial statements included in this filing have been prepared on a basis that assumes that we will continue as a going concern, which contemplates the realization of assets and the satisfaction of liabilities and commitments in the normal course of business. This financial information and these financial statements do not include any adjustments that may result from an unfavorable outcome of this uncertainty. Our ability to continue as a going concern is dependent upon our ability to successfully secure sources of financing and ultimately achieve profitable operations. Use of Estimates The preparation of the Company’s consolidated financial statements in conformity with GAAP requires management to make informed estimates and assumptions that affect the reported amounts of assets, liabilities and expenses and the disclosure of contingent assets and liabilities in the Company’s unaudited condensed consolidated financial statements and accompanying notes. The most significant estimates in the Company’s consolidated financial statements relate to stock-based transactions, accruals for liabilities, operating lease liability, and other matters that affect the condensed consolidated financial statements and related disclosures. Actual results could differ materially from those estimates under different assumptions or conditions and the differences may be material to the condensed Cash and Cash Equivalents Cash represents cash deposits held at financial institutions. The Company considers all liquid investments purchased with an original maturity of three months or less and that can be liquidated without prior notice or penalty to be cash equivalents. Cash equivalents are held for the purpose of meeting short-term liquidity requirements, rather than for investment purposes. The Company had no cash equivalents at March 31, 2020 and December 31, 2019. Concentration of Credit Risk and Other Risks and Uncertainties As of March 31, 2020 and December 31, 2019, all of the Company’s long-lived assets were located in the United States. Financial instruments that are subject to concentration of credit risk consist primarily of cash equivalents. The Company’s policy is to invest cash in institutional money market funds to limit the amount of credit exposure. At times, the Company maintains cash equivalents in short‑term money market funds and it has not experienced any losses on its cash equivalents. The Company’s products will require approval from the U.S. Food and Drug Administration (“FDA”) and foreign regulatory agencies before commercial sales can commence. There can be no assurance that the Company’s products will receive any of these required approvals. The denial or delay of such approvals may impact the Company’s business in the future. In addition, after approval by the FDA, there is still an ongoing risk of adverse events that did not appear during the product approval process. The Company is subject to risks common to companies in the pharmaceutical industry, including, but not limited to, new technological innovations, clinical development risk, establishment of appropriate commercial partnerships, protection of proprietary technology, compliance with government and environmental regulations, uncertainty of market acceptance of products, product liability, the volatility of its stock price and the need to obtain additional financing. Our facilities and equipment, including those of our suppliers and vendors, may be affected by natural or man-made disasters. Our administrative office is based in Irvine, California and we manage all our research and development activities through third parties that are located throughout the world. We have taken precautions to safeguard our facilities, equipment and systems, including insurance, health and safety protocols, and off-site storage of computer data. However, our facilities and systems, as well as those of our third-party suppliers and vendors, may be vulnerable to earthquakes, fire, storm, health emergencies, including the ongoing COVID-19 pandemic, power loss, telecommunications failures, physical and software break-ins, software viruses and similar events which could cause substantial delays in our operations, damage or destroy our equipment or inventory, and cause us to incur additional expenses and delay research and development activities. In addition, the insurance coverage we maintain may not be adequate to cover our losses in any circumstance and may not continue to be available to use on acceptable terms, or at all. Reportable Segments Operating segments under GAAP are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the Chief Operating Decision Maker (“CODM”), or decision-making group, in deciding how to allocate resources and in assessing performance. The CODM is the Company’s Chief Executive Officer and the Company has determined that it operates in one business segment, which is the development of Long-Lived Assets Property and equipment are recorded at cost. Depreciation is computed using the straight-line method over the estimated useful lives of the respective assets. Additions, major renewals and improvements are capitalized, and repair and maintenance costs are charged to expense as incurred. Leasehold improvements are amortized over the remaining life of the initial lease term or the estimated useful lives of the assets, whichever is shorter. The carrying value of long-lived assets, including operating lease right-of-use assets and intangible assets, is evaluated whenever events or changes in business circumstances or the Company’s planned use of long-lived assets indicate, based on undiscounted future operating cash flows, that their carrying amounts may not be fully recoverable or that their useful lives are no longer appropriate. When an indicator of impairment exists, undiscounted future operating cash flows of long-lived assets are compared to their respective carrying value. If the carrying value is greater than the undiscounted future operating cash flows of long-lived assets, the long-lived assets are written down to their respective fair values and an impairment loss is recorded. Fair value is determined primarily using the discounted cash flows expected to be generated from the use of assets. Significant management judgment is required in the forecast of future operating results that are used in the preparation of expected cash flows. No impairments of tangible assets have been identified during the periods presented. Research and Development Expenses Research and development expenses include personnel and facility-related expenses, outside contracted services including clinical trial costs, manufacturing and process development costs, research costs and other consulting services and non-cash stock-based compensation. Research and development costs are expensed as incurred. Amounts due under contracts with third parties may be either fixed fee or fee for service, and may include upfront payments, monthly payments and payments upon the completion of milestones or receipt of deliverables. Non-refundable advance payments under agreements are capitalized and expensed as the related goods are delivered or services are performed. The Company contracts with third parties to perform various clinical trial activities in the on-going development of potential products. The financial terms of these agreements are subject to negotiation, vary from contract to contract and may result in uneven payment flows to its vendors. Payments under the contracts depend on factors such as the achievement of certain events, successful enrollment of patients, and completion of portions of the clinical trial or similar conditions. The Company’s accrual for clinical trials is based on estimates of the services received and efforts expended pursuant to contracts with clinical trial centers and clinical research organizations. These contracts may be terminated by the Company upon written notice and the Company is generally only liable for actual effort expended by the organizations to the date of termination, although in certain instances the Company may be further responsible for termination fees and penalties, as well as reasonable shutdown costs. The Company estimates its research and development expenses and the related accrual as of each balance sheet date based on the facts and circumstances known to the Company at that time. There have been no material adjustments to the Company’s prior‑period accrued estimates for clinical trial activities through March 31, 2020. Net Loss Per Share Basic net loss per common share is calculated by dividing the net loss attributable to common stockholders by the weighted-average number of common shares outstanding during the period, without consideration for potentially dilutive securities. Diluted net loss per share is computed by dividing the net loss attributable to common stockholders by the weighted-average number of common shares and potentially dilutive securities outstanding for the period determined using the treasury-stock and if-converted methods. For purposes of the diluted net loss per share calculation, preferred stock, convertible notes and accrued interest, stock options, warrants and restricted stock units are considered to be potentially dilutive securities and are excluded from the calculation of diluted net loss per share because their effect would be anti-dilutive. Therefore, basic and diluted net loss per share was the same for the periods presented due to the Company’s net loss position. For the Three Months Ended March 31, 2020 2019 (In thousands, except share and per share data) Net loss used in the calculation of basic and diluted loss per share $ (8,177 ) $ (4,881 ) Net loss per share, basic and diluted $ (0.47 ) $ (0.52 ) Weighted-average number of common shares, basic and diluted 17,267,123 9,427,073 The computation of diluted earnings per share excludes stock options, warrants, and restricted stock units that are anti-dilutive. As of March 31, 2020 and 2019, common share equivalents of 9,515,858 shares and 1,241,717 shares were anti-dilutive, respectively. Stock-based Compensation The Company recognizes compensation expense for all stock-based awards based on the grant-date estimated fair value. The fair value of stock options is determined using the Black-Scholes option pricing model, using assumptions that are subjective and require significant judgment and estimation by management. The risk-free rate assumption was based on observed yields from governmental zero-coupon bonds with an equivalent term. The expected volatility assumption was based on historical volatilities of a group of comparable industry companies whose share prices are publicly available. The peer group was developed based on companies in the pharmaceutical industry. The expected term of stock options represents the weighted-average period that the stock options are expected to be outstanding. Because the Company does not have historical exercise behavior, it determined the expected life assumption using the simplified method for options granted to employees, which is an average of the options ordinary vesting period and the contractual term for options granted to nonemployees. The expected dividend assumption was based on the Company’s history and expectation of dividend payouts. The Company has not paid and does not expect to pay dividends at any time in the foreseeable future. The Company recognizes forfeitures on an actual basis and as such did not estimate forfeitures to calculate stock-based compensation. Restricted Stock Units (“RSU”) and Performance-Based Restricted Stock Units (“PRSU”) are measured and recognized based on the quoted market price of our common stock on the date of grant. The Company’s 2014 Stock Incentive Plan (the “2014 Plan”) and 2014 Employee Stock Purchase Plan (the “ESPP” and, together with the 2014 Plan, the “Plans”) each provide for an annual increase in shares available for grant, beginning with the fiscal year ending December 31, 2019 and continuing for each fiscal year until, and including, the fiscal year ending December 31, 2024. In March 2020, the Board of Directors approved an increase of 518,693 shares issuable under the 2014 Plan and 129,673 shares issuable under the ESPP. Th e number of shares reserved for issuance under the 2014 Plan and ESPP were 401,648 and 433,394 shares, respectively, as of March 31, 2020.
