Summary of Significant Accounting Policies | 2. Summary of Significant Accounting Policies Significant Accounting Policies As of January 1, 2019, the Company adopted Accounting Standards Codification or ASC 842 – Leases Basis of Presentation and Use of Estimates The accompanying condensed consolidated financial statements have been prepared in accordance with GAAP. The preparation of the accompanying condensed consolidated financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements, and the reported amounts of expenses during the reporting period. Actual results could differ from those estimates. The accompanying unaudited condensed consolidated financial position as of September 30, 2019 and as of December 31, 2018, the results of operations for each of the three and nine months ended September 30, 2019 and 2018, and cash flows for the three and nine months ended September 30, 2019 and 2018 include the accounts of Aravive, Inc. and its wholly-owned subsidiaries, Versartis Cayman Holdings Company, incorporated in 2014, Versartis GmbH, incorporated in 2015 and Private Aravive, incorporated in 2007, which was not included as a subsidiary in 2018. After 2015, the Cayman and GmbH subsidiaries became dormant. All intercompany accounts and transactions have been eliminated. The U.S. dollar is the functional currency for all the Company's subsidiaries and consolidated operations. As of September 30, 2019, the Company had a cash and cash equivalents balance of approximately $45.0 million consisting of cash and cash equivalents in highly liquid U.S. money market funds. The Company believes that its existing cash and cash equivalents will be sufficient to sustain operations for at least the next 12 months from the issuance of these financial statements, based on its current business plan. The Company’s expected primary use of cash will be to fund the Company’s clinical development programs, specifically for its product candidate AVB-500. Since inception, the Company has incurred net losses and negative cash flows from operations supporting the Company’s clinical development programs and related general and administrative expenses. At September 30, 2019, the Company had an accumulated deficit of approximately $465.8 million and working capital of approximately $42.1 million. The Company expects to continue to incur losses supporting its clinical development program and related administrative expenses. The Company anticipates it may need additional financing to support its business plan as it moves forward. Although management has been successful in raising capital in the past, there can be no assurance that the Company will be successful or that any needed financing will be available in the future at terms acceptable to the Company. Segments The Company operates in one segment. Management uses one measurement of performance and does not segregate its business for internal reporting. All long-lived assets are maintained in the United States of America. Concentration of credit risk Financial instruments that potentially subject the Company to a concentration of credit risk consist of cash and cash equivalents. All of the Company’s cash and cash equivalents are held at several financial institutions that management believes are of high credit quality. Such deposits may exceed federally insured limits. Risk and Uncertainties The Company’s future results of operations involve a number of risks and uncertainties. Factors that could affect the Company’s future operating results and cause actual results to vary materially from expectations include, but are not limited to, uncertainty of results of clinical trials and reaching milestones, uncertainty of regulatory approval of the Company’s potential drug candidates, uncertainty of market acceptance of the Company’s products, competition from substitute products and larger companies, securing and protecting proprietary technology, strategic relationships or a strategic transaction and dependence on key individuals and sole source suppliers. Products developed by the Company require clearances from the U.S. Food and Drug Administration, or the FDA, the Pharmaceuticals Medicines and Devices Agency, or the PMDA, or other international regulatory agencies prior to commercial sales. There can be no assurance that the products will receive the necessary clearances. If the Company was denied clearance, clearance was delayed, or the Company was unable to maintain clearance, it could have a materially adverse impact on the Company. The Company expects to incur substantial operating losses for the next several years and will need to obtain additional financing in order to develop, launch and commercialize any product candidates for which it receives regulatory approval. Cash and c e The Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. At September 30, 2019 and December 31, 2018, the Company’s cash and cash equivalents were held at multiple institutions in the United States and included deposits in money market funds which were unrestricted as to withdrawal or use. Restricted Cash Restricted cash includes cash and cash equivalents that is restricted through legal contracts, regulations or the Company’s intention to use the cash for a specific purpose. The Company’s restricted cash primarily relates to the letter of credit provided to its landlord for the Company’s facilities in Menlo Park, California (as described in Note 5) to secure its obligations under the lease. Property and e Property and equipment are stated at cost and depreciated using the straight-line method over the estimated useful lives of the assets, generally between three and five years. Leasehold improvements are amortized on a straight-line basis over the lesser of their useful life or the term of the lease. Maintenance and repairs are charged to expense as incurred, and improvements are capitalized. When assets are retired or otherwise disposed of, the cost and accumulated depreciation are removed from the balance sheet and any resulting gain or loss is reflected in operations in the period realized. Leases The Company adopted ASC 842 on January 1, 2019. For the periods prior to January 1, 2019, the Company’s leases were accounted for under ASC 840. The Company leases all of its office space in conducting its business. At inception, the Company determines whether an agreement represents a lease and at commencement the Company evaluates each lease agreement to determine whether the lease is an operating or financing lease. As described below under "Recent Accounting Pronouncements”, the Company adopted the Financial Accounting Standards Board Accounting Standards Update, or ASU, "Leases," or ASU 2016-02. The Company elected to adopt the standard on January 1, 2019 using the alternative transition method provided by ASU 2018-11 whereby the Company recorded right-of-use (“ROU”) assets and lease liabilities for its existing leases as of January 1, 2019, as well as a cumulative-effect adjustment to accumulated deficit of initially applying the new standard as of January 1, 2019. The new standard provides a number of optional practical expedients in transition. The Company has elected the practical expedients to not reassess its prior conclusions about lease identification under the new standard, to not reassess lease classification, and to not reassess initial direct costs. The Company has elected the practical expedient allowing the use-of-hindsight which doesn’t require the Company to reassess the lease term of its leases based on all facts and circumstances through the effective date. With the adoption of ASU 2016-02, the Company recorded an operating lease right-of-use asset and an operating lease obligation on the consolidated balance sheet. ROU assets represent the Company’s ROU of the underlying asset for the lease term and the lease obligation represents the Company’s commitment to make the lease payments arising from the lease. ROU obligations are recognized at the commencement date based on the present value of remaining lease payments over the lease term and ROU assets are calculated as the lease liability, adjusted by unamortized initial direct costs, unamortized lease incentives received, cumulative deferred or prepaid lease payments, and accumulated impairment losses. As the Company’s leases do not provide an implicit rate, the Company has used an estimated incremental borrowing rate based on the information available at the adoption date in determining the present value of lease payments. The lease term may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Operating lease expense is recognized on a straight-line basis over the lease term, subject to any changes in the lease or expectations regarding the terms. Variable lease costs such as common area costs and property taxes are expensed as incurred. For all lease agreements the Company has combined lease and nonlease components. Leases with an initial term of 12 months or less are not recorded on the balance sheet. Prior to the Company’s adoption of ASU 2016-02, when the Company’s lease agreements contained renewal options, tenant improvement allowances, rent holidays and rent escalation clauses, the Company recorded a deferred rent asset or liability equal to the difference between the rent expense and the future minimum lease payments due. The lease expense related to operating leases was recognized on a straight-line basis in the statements of operations over the term of each lease. Impairment of Long-Lived Assets The Company reviews property and equipment for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability is measured by the comparison of the carrying amount to the future net cash flows which the assets are expected to generate. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value (i.e. determined through estimating projected discounted future net cash flows or other acceptable methods of determining fair value) arising from the asset. There have been no such impairments of long-lived assets as of September 30, 2019 or December 31, 2018. Fair Value of Financial Instruments The carrying value of the Company’s cash and cash equivalents, prepaid expenses, accounts payable and accrued liabilities approximate fair value due to the short-term nature of these items. Fair value is defined as the exchange price that would be received for an asset or an exit price paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The fair value hierarchy defines a three-level valuation hierarchy for disclosure of fair value measurements as follows: Level 1 Unadjusted quoted prices in active markets for identical assets or liabilities; Level 2 Inputs other than quoted prices included within Level Level 3 Unobservable inputs that are supported by little or no market activity for the related assets or liabilities. The categorization of a financial instrument within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The Company’s financial instruments consist of Level 1 assets as of September 30, 2019. Level 1 assets are comprised of highly liquid money market funds. Preclinical and Clinical Trial Accruals The Company’s clinical trial accruals are based on estimates of patient enrollment and related costs at clinical investigator sites as well as estimates for the services received and efforts expended pursuant to contracts with multiple research institutions and clinical research organizations, or CROs, that conduct and manage clinical trials on the Company’s behalf. The Company estimates preclinical and clinical trial expenses based on the services performed, pursuant to contracts with research institutions and clinical research organizations that conduct and manage preclinical studies and clinical trials on its behalf. In accruing service fees, the Company estimates the time period over which services will be performed and the level of patient enrollment and activity expended in each period. If the actual timing of the performance of services or the level of effort varies from the estimate, the Company will adjust the accrual accordingly. Payments made to third parties under these arrangements in advance of the receipt of the related services are recorded as prepaid expenses until the services are rendered. Research and d Research and development costs are charged to operations as incurred. Research and development costs include, but are not limited to, payroll and personnel expenses, laboratory supplies, consulting costs, external research and development expenses and allocated overhead, including rent, equipment depreciation, and utilities. Costs to acquire technologies to be used in research and development that have not reached technological feasibility and have no alternative future use are expensed to research and development costs when incurred. Income t The Company accounts for income taxes under the asset and liability approach. Under this method, deferred tax assets and liabilities are determined based on the difference between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to affect taxable income. Valuation allowances are established when necessary to reduce deferred tax assets to the amounts expected to be realized. The Company assesses all material positions taken in any income tax return, including all significant uncertain positions, in all tax years that are still subject to assessment or challenge by relevant taxing authorities. Assessing an uncertain tax position begins with the initial determination of the position’s sustainability and is measured at the largest amount of benefit that is greater than percent likely of being realized upon ultimate settlement. As of each balance sheet date, unresolved uncertain tax positions must be reassessed, and the Company will determine whether (i) the factors underlying the sustainability assertion have changed and (ii) the amount of the recognized tax benefit is still appropriate. The recognition and measurement of tax benefits requires significant judgment. Judgments concerning the recognition and measurement of a tax benefit might change as new information becomes available. Stock-Based c For stock options granted to employees, the Company recognizes compensation expense for all stock-based awards based on the grant-date estimated fair value. The value of the portion of the award that is ultimately expected to vest is recognized as expense ratably over the requisite service period. The fair value of stock options is determined using the Black-Scholes option pricing model. The determination of fair value for stock-based awards on the date of grant using an option pricing model requires management to make certain assumptions regarding a number of complex and subjective variables. Stock-based compensation expense related to stock options granted to nonemployees is recognized based on the fair value of the stock options, determined using the Black-Scholes option pricing model, as they are earned. The awards generally vest over the time period the Company expects to receive services from the nonemployee. Stock-based compensation expense, net of estimated forfeitures, is reflected in the condensed consolidated statements of operations and comprehensive loss as follows (in thousands): Three Months Ended Nine Months Ended September 30, September 30, 2019 2018 2019 2018 Operating Expenses Research and development $ 120 $ 95 $ 318 $ 1,855 General and administrative 680 1,218 2,471 4,434 Total $ 800 $ 1,313 $ 2,789 $ 6,289 Comprehensive Loss Comprehensive loss is defined as a change in equity of a business enterprise during a period, resulting from transactions from non-owner sources. Specifically, the Company includes cumulative foreign currency translation adjustments and net unrealized gains. There was no difference between net loss and comprehensive loss for all periods presented. Net Loss per Share of Common Stock 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. For purposes of the diluted net loss per share calculation, stock options, restricted stock units and shares issued under the Company’s Employee Stock Purchase Plan are considered to be potentially dilutive securities. Because the Company has reported a net loss for all of the periods presented, diluted net loss per common share is the same as basic net loss per common share for those periods. Intangible Asset Intangible assets consist of an assembled workforce which was acquired as part of the Merger. Intangible assets with definite lives are amortized based on their pattern of economic benefit over their estimated useful lives and reviewed periodically for impairment. The estimated useful life of the assembled workforce is 3 years. Revenue Recognition The Company’s sole source of revenue for 2019 and 2018 was grant revenue related to the CPRIT Grant, which is being recognized when qualifying costs are incurred and there is reasonable assurance that the conditions of the award have been met for collection. Proceeds received prior to the costs being incurred or the conditions of the award being met are recognized as deferred revenue until the services are performed and the conditions of the award are met. For the nine months ended September 30, 2019, the Company has recognized approximately $4.8 million from the CPRIT Grant. Funds received are reflected in deferred revenue as a liability until revenue is earned. Grant revenue is recognized when qualifying costs are incurred. As of September 30, 2019, the Company had an unbilled receivable from CPRIT of $2.0 million, which is reflected in prepaid expenses and other current assets on the accompanying condensed consolidated balance sheet. Quarterly reclassifications Certain reclassi fications of prior period amounts have been made within the Company’s Quarterly Report on Form 10-Q for the quarter ended September 30, 2019. Specifically, during the fourth quarter ended December 31, 2018, the Company determined that the amount related to the inducement on build-to-suit lease obligation as reflected within one line in the investing activities section of the unaudited consolidated statement of cash flows for the nine months ended September 30, 2018 included in the Form 10-Q, should have been classified as cash flows provided from financing activities. There is no impact to the consolidated statements of operations and comprehensive loss or consolidated balance sheets for any of these periods. The Company evaluated the effect of this misclassification and concluded it was not material to any of its previously issued unaudited consolidated financial statements. Upon revision, cash flows from investing activities for the nine months ended September 30, 2018, decreased by $1.9 million and cash flows from financing activities for the respective period increased by $1.9 million. This adjustment had no impact to the Company’s financial position, results of operations or cash flows as of and for the year ended December 31, 2018. Recent Accounting Pronouncements From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board, or FASB, or other standard setting bodies and adopted by us as of the specified effective date. Unless otherwise discussed, the impact of recently issued standards that are not yet effective is not expected to have a material impact on the Company’s financial position or results of operations upon adoption. In June 2018, the FASB issued ASU No. 2018-07, Compensation – Stock Compensation (Topic 718) - Improvements to Nonemployee Share-Based Payment Accounting . This amendment provides additional guidance related to share-based payment transactions for acquiring goods or services from nonemployees. The guidance will be effective for the Company for fiscal years beginning after December 15, 2018, including the interim periods within that fiscal year. The Company has adopted this new guidance as of January 1, 2019, which had no material impact on the Company’s consolidated financial statements. In June 2018, the FASB issued Not-For-Profit Entities (Topic 958): Clarifying the Scope and the Accounting Guidance for Contributions Received and Contributions Made , which is intended to clarify and improve the scope and the accounting guidance for contributions received and contributions made. The amendments in should assist entities in (1) evaluating whether transactions should be accounted for as contributions (nonreciprocal transaction) within the scope of Topic 958, Not-for-Profit Entities, or as exchange (reciprocal) transactions subject to other guidance and (2) determining whether a contribution is conditional. This amendment applies to all entities that make or receive grants or contributions. This ASU is effective for public companies serving as a resource recipient for fiscal years beginning after June 15, 2018, including interim periods within that fiscal year. The Company has adopted this guidance as of January 1, 2019 which had no material impact to its consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). This ASU is a comprehensive new leases standard that amends various aspects of existing guidance for leases and requires additional disclosures about leasing arrangements. The new standard requires that all lessees recognize the assets and liabilities that arise from leases on the balance sheet and disclose qualitative and quantitative information about its leasing arrangements. The classification criteria for distinguishing between finance leases and operating leases are substantially similar to the classification criteria for distinguishing between capital leases and operating leases in the previous lease guidance. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, and interim periods within those years, with early adoption permitted. In transition, lessees and lessors are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. In July 2018, the FASB issued ASU 2018-11, Leases (Topic 842)-- Targeted Improvements, that allows entities to apply the provisions of the new standard at the effective date (e.g. January 1, 2019), as opposed to the earliest period presented under the modified retrospective transition approach (January 1, 2017) and recognize a cumulative-effect adjustment to the opening balance of accumulated deficit in the period of adoption. The modified retrospective approach includes a number of optional practical expedients primarily focused on leases that commenced before the effective date of Topic 842, including continuing to account for leases that commence before the effective date in accordance with previous guidance, unless the lease is modified. The Company adopted ASC Topic 842 with the cumulative effect of adoption recognized to accumulated deficit on January 1, 2019, as described in Note 2. As a result of the adoption of ASC 842 on January 1, 2019, the Company derecognized $8.6 million for the existing asset; $7.3 million for the obligation and $1.3 million to the opening balance of the accumulated deficit. The existing asset and obligation on the consolidated balance sheet resulted from the build-to-suit lease arrangement at 1020 Marsh Road, Menlo Park, California or the 1020 Space Additionally, as a result of adoption of ASC 842, the Company recognized operating lease ROU assets of approximately $10.4 million, $2.1 million of leasehold improvements, an operating lease obligation of $12.6 million and derecognition of deferred rent of $0.1 million as of January 1, 2019. |
