DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	1. DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Description of Business BioPharmX Corporation (the “Company”) is incorporated under the laws of the state of Delaware and originally incorporated on August 30, 2010 in Nevada under the name Thompson Designs, Inc. The Company has one wholly-owned subsidiary, BioPharmX, Inc., a Nevada corporation. The Company is a specialty pharmaceutical company focused on utilizing its proprietary drug delivery technologies to develop and commercialize novel prescription products that address large markets in dermatology. The Company’s objective is to develop products that treat health or age-related conditions that (1) are not presently being addressed or treated at all or (2) are currently treated with drug therapies or drug delivery approaches that are suboptimal. The Company’s strategy is designed to bring new products to market by identifying optimal delivery mechanisms and/or alternative applications for United States Food and Drug Administration (FDA) approved active pharmaceutical ingredients and biological materials, while, in appropriate circumstances, reducing the time, cost and risk typically associated with new product development by repurposing drugs with demonstrated safety profiles and, when applicable, taking advantage of the regulatory approval pathway under Section 505(b)(2) of the Federal Food, Drug and Cosmetic Act. The Company believes these approaches may reduce drug development risk and could reduce the time and resources it spends during development. Its current platform technologies include innovative delivery mechanisms for antibiotics, biologic materials and molecular iodine (I₂). Since the Company’s inception, substantially all of the Company’s efforts have been devoted to developing its product candidates, including conducting preclinical and clinical trials, and providing general and administrative support for its operations. The Company has financed its operations primarily through the sale of equity and convertible notes. Basis of Presentation and Principles of Consolidation These unaudited interim condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (GAAP) and applicable rules and regulations of the Securities and Exchange Commission (SEC) regarding interim financial reporting. Certain information and note disclosures normally included in the consolidated financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. Accordingly, these unaudited interim condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto contained in the Company’s Annual Report on Form 10-K for the year ended January 31, 2018, filed on April 26, 2018. The condensed consolidated balance sheet as of January 31, 2018, included herein, was derived from the audited consolidated financial statements as of that date. The unaudited interim condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary and have been prepared on the same basis as the audited consolidated financial statements and include all adjustments, consisting only of normal recurring adjustments, necessary for the fair presentation of the Company’s statement of financial position as of October 31, 2018 and January 31, 2018, and the Company’s results of operations for the three and nine months ended October 31, 2018 and 2017 and its cash flows for the nine months ended October 31, 2018 and 2017. The results for the three and nine months ended October 31, 2018 are not necessarily indicative of the results to be expected for the year ending January 31, 2019 or any future period. Use of Estimates The preparation of 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 financial statements and reported amounts of revenues and expenses recognized during the reported period. Actual results could differ from those estimates. Inventories Inventories are stated at the lower of cost or net realizable value. Cost is determined using the standard cost method which approximates actual cost on a first-in, first-out basis. The Company regularly reviews inventory quantities in consideration of actual loss experiences, projected future demand and remaining shelf life to record a provision for inventory, which may have become obsolete or are in excess of anticipated demand or net realizable value. If future demand or market conditions for the products are less favorable than forecasted, the Company may be required to record additional write-downs, which would negatively affect its results of operations in the period when the write-downs were recorded. The Company must order components for its products and build inventory in advance of product shipments. The Company has a purchase commitment relating to the manufacturing of VI₂OLET finished product (iodine supplement tablets) and is non-cancelable as detailed in Note 5. The Company assesses its purchase commitment based on demand forecasts and establishes a liability for quantities deemed in excess of these forecasts. Impairment of Long-Lived Assets The Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset might not be recoverable. When such an event occurs, management determines whether there has been an impairment by comparing the anticipated undiscounted future net cash flows to the related asset’s carrying value. If an asset is considered impaired, the asset is written down to fair value, which is determined based either on discounted cash flows or appraised value, depending on the nature of the asset. The Company did not identify any impairment losses for the three or nine months ended October 31, 2018. Advertising Expenses The Company expenses the costs of advertising, including promotional expenses, as incurred. Advertising expenses were approximately $5,000 and $4,000 for the three months ended October 31, 2018 and 2017, respectively, and approximately $9,000 and $23,000 for the nine months ended October 31, 2018 and 2017, respectively. Net Loss per Share Basic net loss per share is calculated based on the weighted-average number of shares of the Company’s common stock outstanding during the period. The weighted-average shares outstanding for the three and nine months ended October 31, 2018 and 2017 excludes 193,333 shares of unvested restricted common stock. Diluted net loss per share attributable to common stockholders is calculated based on the weighted-average number of shares of the Company’s common stock outstanding and other dilutive securities outstanding during the period. As of October 31, 2018 and 2017, approximately 190,102,000 and 58,382,000 of potentially dilutive securities, respectively, were excluded from the computation of diluted net loss per share because their effect on net loss per share would be anti-dilutive. Warrant Liability The Company accounts for certain of its warrants as derivative liabilities based on provisions relating to cash settlement options. The Company recorded a liability for the fair value of the warrants at the time of issuance, and at each reporting date the warrants are revalued to the instrument’s fair value. The fair value of the warrants are estimated using the Black-Scholes pricing model. This liability is subject to fair value re-measurement until the warrants are exercised or expired, and any change in fair value is recognized as other income or expense in the condensed consolidated statements of operations and comprehensive loss. Revenue Recognition Effective February 1, 2018, the Company adopted Financial Accounting Standards Board (FASB) Accounting Standards Codification Topic 606, Revenue from Contracts with Customers (ASC 606), using the modified retrospective transition method. The cumulative effect of the initial application of ASC 606 of approximately $2,000 was recognized as an adjustment to accumulated deficit and a decrease to deferred revenue as of February 1, 2018. The adoption of ASC 606 did not have a material impact on the Company’s condensed consolidated balance sheet, statement of operations and comprehensive loss for the three or nine months ended October 31, 2018 and statement of cash flows for the nine months ended October 31, 2018. Revenue recognized to date is from the sale of VI₂OLET, an iodine dietary supplement. Revenue is recognized when control is transferred to the customer, which is typically upon shipment. There are no significant post-shipment obligations. Revenue is recognized at the transaction price, which includes estimates of variable consideration for reserves related to estimated product returns, pricing discounts or other concessions. These estimates are based on estimates of the amount earned or to be claimed on the related sales and are based on historical information and current contractual requirements. The Company continually evaluates whether the revenue generating activities and advanced payment arrangements with customers result in the recognition of contract assets or liabilities. No such assets existed as of October 31, 2018 or February 1, 2018. Separately, accounts receivable, net, represent receivables from contracts with customers. As of October 31, 2018 and February 1, 2018, deferred revenue was immaterial. The Company applies the practical expedient to make adjustments for a significant financing component unnecessary if, at contract inception, the Company does not expect the period between customer payment and transfer of control of the promised goods or services to the customer to exceed one year. During the three and nine months ended October 31, 2018, the Company did not have any contracts for the sale of its products with its customers with a significant financing component. The Company has elected the practical expedient to recognize the incremental costs of obtaining a contract as an expense when incurred if the amortization period of the asset that the Company otherwise would have recognized is one year or less. During the three and nine months ended October 31, 2018, the Company expensed the incremental costs of obtaining the contract as an expense when incurred as the amortization period was one year or less. Shipping costs billed to customers are recorded as revenue. Shipping and handling expense related to costs incurred to deliver product are recognized within cost of goods sold. The Company accounts for shipping and handling activities that occur after control has transferred as a fulfillment cost as opposed to a separate performance obligation, and the costs of shipping and handling are recognized concurrently with the related revenue. Summary of Significant Accounting Policies These unaudited interim condensed consolidated financial statements and accompanying notes should be read in conjunction with the Company’s annual consolidated financial statements and notes thereto contained in the Annual Report on Form 10-K for the fiscal year ended January 31, 2018. There have been no significant changes in the Company’s significant accounting policies for the three and nine months ended October 31, 2018, except for the adoption of ASC 606 as discussed above, as compared to the significant accounting policies described in the Annual Report on Form 10-K for the fiscal year ended January 31, 2018. Recent Accounting Pronouncements In February 2016, the FASB issued Accounting Standards Update 2016-02, Leases, and in July 2018, Accounting Standards Update 2018-11, Targeted Improvements, which requires entities to recognize assets and liabilities for leases with lease terms greater than twelve months. The new guidance also requires quantitative and qualitative disclosures regarding the amount, timing and uncertainty of cash flows arising from leases. The standard is effective for annual and interim periods beginning after December 15, 2018, with early adoption permitted upon issuance. The Company is in the process of evaluating the impact of adoption of this standard on its condensed consolidated financial statements. In June 2018, the FASB issued Accounting Standards Update 2018-07, Improvements to Nonemployee Share-Based Payment Accounting, which simplifies the accounting for share-based payments to nonemployees by aligning it with the accounting for share-based payments to employees, with certain exceptions. The amendment is effective for annual and interim periods beginning after December 15, 2018, with early adoption permitted. The Company is in the process of evaluating the impact of adoption of this amendment on its condensed consolidated financial statements. The Company has reviewed other recent accounting pronouncements and concluded they are either not applicable to the business or no material effect is expected on the condensed consolidated financial statements as a result of future adoption.
