Accounting Policies [Abstract] |
Basis of Presentation | Basis of Presentation The accompanying unaudited consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). Certain information and note disclosures normally included in annual financial statements prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) have been omitted. The accompanying unaudited consolidated financial statements include all known adjustments necessary for a fair presentation of the results of interim periods as required by U.S. GAAP. These adjustments consist primarily of normal recurring accruals and estimates that impact the carrying value of assets and liabilities. Also, certain reclassifications have been made to 2019 financial information to conform to the current year presentation of prepaid expenses and other assets on the Consolidated Statements of Cash Flows. Operating results for the nine months ended September 30, 2020 are not necessarily indicative of the results that may be expected for the year ending December 31, 2020. Interim results are not necessarily indicative of results for a full year, particularly in light of the novel coronavirus (“COVID-19”) pandemic, and its impact on domestic and global economies. To limit the spread of COVID-19, governments have taken various actions, including the issuance of stay-at-home orders and social distancing guidelines, which have resulted in some businesses suspending operations or experiencing a reduction in demand for many products from direct or ultimate customers. Accordingly, businesses have adjusted, reduced or suspended operating activities. The effects of the stay-at-home orders and our work-from-home policies may negatively impact productivity, disrupt our business, and delay our development programs and regulatory and commercialization timelines, the magnitude of which will depend, in part, on the length and severity of the restrictions and other limitations on our ability to conduct our business in the ordinary course. Our future research and development expenses and general and administrative expenses may vary significantly if we experience an increased impact from the COVID-19 pandemic on the costs and timing associated with the conduct of our clinical trials and other related business activities. The financial statements should be read in conjunction with our audited financial statements for the year ended December 31, 2019 included in our Annual Form 10-K.
Basis of Consolidation | Basis of ConsolidationThe accompanying consolidated financial statements include us and our wholly-owned Australian subsidiary. All intercompany accounts and transactions have been eliminated in consolidation. We operate in one reportable segment, and our functional and reporting currency is the U.S. dollar.
Use of Estimates | Use of Estimates The preparation of the accompanying consolidated financial statements in conformity with U.S. GAAP requires our management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates. We base our estimates and assumptions on historical experience when available and on various factors that we believe to be reasonable under the circumstances. We evaluate our estimates and assumptions on an ongoing basis. The full extent to which the COVID-19 pandemic will directly or indirectly impact our business, results of operations, and financial condition, including expenses, reserves and allowances, manufacturing, clinical trials, research and development costs, and employee-related amounts, will depend on future developments that are highly uncertain, including as a result of new information that may emerge concerning COVID-19 and the actions taken to contain or treat it, as well as the economic impact on local, regional, national and international markets. Our actual results could differ from these estimates under different assumptions or conditions.
Net Loss Per Common Share | Net Loss Per Common Share Basic net loss per common share is computed by dividing net loss by the weighted-average number of common shares outstanding during the period. Diluted net loss per share is computed by dividing net loss by the weighted-average number of common equivalent shares outstanding for the period, as well as any dilutive effect from outstanding stock options and warrants using the treasury stock method. For each period presented, there is no difference in the number of shares used to calculate basic and diluted net loss per share.
Accounting Pronouncements Recently Adopted | Accounting Pronouncements Recently Adopted In December 2019, the Financial Accounting Standards Board (the “FASB”) issued ASU 2019-12, Income Taxes (Topic 740) intended to simplify the accounting for income taxes. The guidance removes the following exceptions: (1) exception to the incremental approach for intraperiod tax allocation when there is a loss from continuing operations and income or a gain from other items, (2) exception to the requirement to recognize a deferred tax liability for equity method investments when a foreign subsidiary becomes an equity method investment, (3) exception to the ability not to recognize a deferred tax liability for a foreign subsidiary when a foreign equity method investment becomes a subsidiary, and (4) exception to the general methodology for calculating income taxes in an interim period when a year-to-date loss exceeds the anticipated loss for the year. Additionally, the guidance simplifies the accounting for income taxes by: (1) requiring that an entity recognize a franchise tax (or similar tax) that is partially based on income as an income-based tax and account for any incremental amount incurred as a non-income-based tax, (2) requiring that an entity evaluate when a step up in the tax basis of goodwill should be considered part of the business combination in which the book goodwill was originally recognized and when it should be considered a separate transaction, (3) specifying that an entity is not required to allocate the consolidated amount of current and deferred tax expense to a legal entity that is not subject to tax in its separate financial statements (although the entity may elect to do so (on an entity-by-entity basis) for a legal entity that is both not subject to tax and disregarded by the taxing authority), (4) requiring that an entity reflect the effect of an enacted change in tax laws or rates in the annual effective tax rate computation in the interim period that includes the enactment date, and (5) making minor improvements for income tax accounting related to employee stock ownership plans and investments in qualified affordable housing projects accounted for using the equity method. The guidance will be effective for fiscal years and interim periods beginning after December 15, 2020. Different components of the guidance require retrospective, modified retrospective or prospective adoption, and early adoption is permitted. We early adopted this standard on January 1, 2020, and the adoption of the standard did not have a material impact to our consolidated financial statements. In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses: Measurement of Credit Losses on Financial Instruments (Topic 326), which changes the accounting treatment for recognizing the impairment of financial assets. Under the new guidance, credit losses for certain types of financial instruments will be estimated based on expected losses. The new guidance also eliminates the other-than-temporary impairment model for available-for-sale (“AFS”) debt securities. Entities will begin to recognize credit losses on AFS debt securities as allowances rather than as reductions in the carrying value of the securities. Impairment that is not credit-related impairment will continue to be recognized in other comprehensive income and entities will no longer consider the length of time a security has been in an unrealized loss position when determining whether a credit loss exists. ASU 2016-13 becomes effective for annual and interim periods beginning after December 15, 2019. We adopted this standard prospectively on January 1, 2020, and the adoption of the standard did not have a material impact to our consolidated financial statements as credit losses are not expected to be significant based on historical trends, the financial condition of our investments and external market factors. We will continue to actively monitor the impact of the COVID-19 pandemic on expected credit losses.
