Accounting Policies [Abstract] |
Consolidation, Policy [Policy Text Block] | Principles of Consolidation The accompanying consolidated financial statements include the accounts of GeoVax Labs, Inc. together with those of our wholly-owned subsidiaries, GeoVax, Inc. and Immutak Oncology, Inc. All intercompany transactions have been eliminated in consolidation.
Basis of Accounting, Policy [Policy Text Block] | Basis of Presentation As described in Notes 7 and 11, effective April 30, 2019, we enacted a one -for- five hundred reverse stock split of our common stock, and effective January 21, 2020, we further enacted a one -for- two thousand reverse split. The accompanying financial statements, and all share and per share information contained herein, have been retroactively restated to reflect the reverse stock splits. The accompanying consolidated financial statements have been prepared assuming that we will continue as a going concern, which contemplates realization of assets and the satisfaction of liabilities in the normal course of business for the twelve -month period following the date of these consolidated financial statements. We are devoting substantially all of our present efforts to research and development. We have funded our activities to date from government grants and clinical trial assistance, and from sales of our equity securities. We will continue to require substantial funds to continue our research and development activities. We believe that our existing cash resources and government and other collaborative funding commitments will be sufficient to continue our planned operations into the second quarter of 2020. Due to our history of operating losses and our continuing need for capital to conduct our research and development activities, there is substantial doubt concerning our ability to operate as a going concern beyond that date. We are currently exploring sources of capital through additional government grants and corporate collaborations. We also intend to secure additional funds through sales of our equity securities or by other means. Management believes that we will be successful in securing the additional capital required to continue the Company’s planned operations, but that our plans do not fully alleviate the substantial doubt about the Company’s ability to operate as a going concern. Additional funding may not be available on favorable terms or at all. If we fail to obtain additional capital when needed, we will be required to delay, scale back, or eliminate some or all of our research and development programs as well as reduce our general and administrative expenses.
Use of Estimates, Policy [Policy Text Block] | Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles (GAAP) requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results may differ from those estimates.
Cash and Cash Equivalents, Policy [Policy Text Block] | Cash and Cash Equivalents We consider all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents. Our cash and cash equivalents consist primarily of bank deposits and money market accounts. The recorded values approximate fair market values due to the short maturities.
Fair Value of Financial Instruments, Policy [Policy Text Block] | Fair Value of Financial Instruments and Concentration of Credit Risk Financial instruments that subject us to concentration of credit risk consist primarily of cash and cash equivalents, which are maintained by a high credit quality financial institution. The carrying values reported in the balance sheets for cash and cash equivalents approximate fair values.
Property, Plant and Equipment, Policy [Policy Text Block] | Property and Equipment Property and equipment are stated at cost, less accumulated depreciation and amortization. Expenditures for maintenance and repairs are charged to operations as incurred, while additions and improvements are capitalized. We calculate depreciation using the straight-line method over the estimated useful lives of the assets which range from three to five years. We amortize leasehold improvements using the straight-line method over the term of the related lease. In February 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update No. 2016 - 02, Leases (ASU 2016 - 02 ). ASU 2016 - 02 sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e. lessees and lessors). The new standard requires lessees to classify leases as either financing or operating leases based on the principle of whether or not the lease is effectively a financed purchase by the lessee. This classification determines whether lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease, respectively. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months regardless of their classification. Leases with a term of 12 months or less will be accounted for similar to prior guidance for operating leases. We adopted ASU 2016 - 02 effective January 1, 2019; such adoption had no material impact on our financial statements, given that the noncancelable term of our current lease is less than 12 months (see Note 6 ).
Impairment or Disposal of Long-Lived Assets, Policy [Policy Text Block] | Impairment of Long-Lived Assets We review long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of the assets to the future net cash flows expected to be generated by such assets. If we consider such assets to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the expected future net cash flows from the assets.
Accrued Liabilities [Policy Text Block] | Accrued Expenses As part of the process of preparing our financial statements, we estimate expenses that we believe we have incurred, but have not yet been billed by our third -party vendors. This process involves identifying services and activities that have been performed by such vendors on our behalf and estimating the level to which they have been performed and the associated cost incurred for such service as of each balance sheet date.
Earnings Per Share, Policy [Policy Text Block] | Net Loss Per Share Basic and diluted loss per common share are computed based on the weighted average number of common shares outstanding. Common share equivalents consist of common shares issuable upon conversion of convertible preferred stock, and upon exercise of stock options and stock purchase warrants. All common share equivalents are excluded from the computation of diluted loss per share since the effect would be anti-dilutive. The weighted average number of common share equivalents which were excluded from the computation of diluted loss per share, totaled 11,157 and 193 shares at December 31, 2019 and 2018, respectively. See Note 7 for more information concerning our outstanding common share equivalents at December 31, 2019 that could potentially dilute earnings per share in the future. In July 2017, the FASB issued Accounting Standards Update 2017 - 11, (Part I) Accounting for Certain Financial Instruments with Down Round Features, (Part II) Replacement of the Indefinite Deferral for Mandatorily Redeemable Financial Instruments of Certain Nonpublic Entities and Certain Mandatorily Redeemable Noncontrolling Interests with a Scope Exception (“ASU 2017 - 11” ), which amends Accounting Standards Codification Topic 260, Earnings Per Share, Topic 480, Distinguishing Liabilities from Equity, and Topic 815, Derivatives and Hedging. ASU 2017 - 11 changes the classification of certain equity-linked financial instruments (or embedded features) with down round features and clarifies existing disclosure requirements for equity-classified instruments. We adopted ASU 2017 - 11 effective January 1, 2019; such adoption had no material impact on our financial statements.
Revenue from Contract with Customer [Policy Text Block] | Revenue Recognition In May 2014, the FASB issued Accounting Standards Update 2014 - 09, Revenue from Contracts with Customers (ASU 2014 - 09 ), which created a new Topic, Accounting Standards Codification Topic 606. The standard is principle-based and provides a five -step model to determine when and how revenue is recognized. The core principle is that an entity should recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. We adopted ASU 2014 - 09 effective January 1, 2018 using the modified retrospective transition method. Under this method, our prior results will remain as reported and starting in 2018 are recognized under the new method. The adoption of ASU 2014 - 09 had no material impact on the measurement, timing, or recognition of our grant and collaboration revenues, nor on the related research and development expenses. Grant revenue – We receive payments from government entities under non-refundable grants in support of our vaccine development programs. We record revenue associated with these grants when the reimbursable costs are incurred and we have complied with all conditions necessary to receive the grant funds. Research collaborations – We are pursuing a strategy of co-developing or licensing our technology for specific vaccine development approaches and/or disease indications. We have entered into multiple collaborative research and development agreements and have received third -party funding for preclinical research under certain of these arrangements. Each agreement is evaluated in accordance with the process defined by ASU 2014 - 09 and revenue is recognized accordingly.
Research and Development Expense, Policy [Policy Text Block] | Research and Development Expense Research and development expense primarily consists of costs incurred in the discovery, development, testing and manufacturing of our product candidates. These expenses consist primarily of (i) salaries, benefits, and stock-based compensation for personnel, (ii) laboratory supplies and facility-related expenses to conduct development, (iii) fees paid to third -party service providers to perform, monitor and accumulate data related to our preclinical studies and clinical trials, (iv) costs related to sponsored research agreements, and (v) costs to procure and manufacture materials used in clinical trials. These costs are charged to expense as incurred.
Intangible Assets, Finite-Lived, Policy [Policy Text Block] | Patent Costs Our expenditures relating to obtaining and protecting patents are charged to expense when incurred and are included in general and administrative expense.
Reclassification, Policy [Policy Text Block] | Period - to - Period Comparisons Our operating results are expected to fluctuate for the foreseeable future. Therefore, period-to-period comparisons should not be relied upon as predictive of the results for future periods.
Income Tax, Policy [Policy Text Block] | Income Taxes We account for income taxes using the liability method. Under this method, deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted rates in effect for the year in which temporary differences are expected to be recovered or settled. Deferred tax assets are reduced by a valuation allowance unless, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will be realized.
Share-based Payment Arrangement [Policy Text Block] | Stock-Based Compensation We account for stock-based transactions in which the Company receives services from employees, directors or others in exchange for equity instruments based on the fair value of the award at the grant date. Stock-based compensation cost for awards of common stock is estimated based on the price of the underlying common stock on the date of issuance. Stock-based compensation cost for stock options or warrants is estimated at the grant date based on each instrument’s fair value as calculated by the Black-Scholes option pricing model. We recognize stock-based compensation cost as expense ratably on a straight-line basis over the requisite service period for the award. See Note 7 for additional stock-based compensation information. In May 2017, the FASB issued Accounting Standards Update 2017 - 09, Scope of Modification Accounting (“ASU 2017 - 09” ), which amends Accounting Standards Codification Topic 718, Compensation – Stock Compensation. ASU 2017 - 09 is an attempt to provide clarity and reduce both ( 1 ) diversity in practice and ( 2 ) cost and complexity when applying the guidance in Topic 718 Compensation – Stock Compensation, to a change to the terms or conditions of a share-based payment award. We adopted ASU 2017 - 09 effective January 1, 2018; such adoption had no material impact on our financial statements. In June 2018, the FASB issued Accounting Standards Update 2018 - 07, Improvements to Nonemployee Share-Based Payment Accounting (ASU 2018 - 07 ), that expands the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees. We adopted ASU 2018 - 07 effective January 1, 2019; such adoption had no material impact on our financial statements.
New Accounting Pronouncements, Policy [Policy Text Block] | Other Recent Accounting Pronouncements Except as discussed above, there have been no recent accounting pronouncements or changes in accounting pronouncements which we expect to have a material impact on our financial statements, nor do we believe that any recently issued, but not yet effective, accounting standards if currently adopted would have a material effect on our financial statements.
