NATURE OF OPERATIONS and SIGNIFICANT ACCOUNTING POLICIES | NOTE 1 NATURE OF OPERATIONS and SIGNIFICANT ACCOUNTING POLICIES Business Dipexium Pharmaceuticals, Inc. (the “Company” or “Dipexium”), a Delaware corporation, formerly Dipexium Pharmaceuticals, LLC, is a pharmaceutical company focused on the development and commercialization of Locilex® (pexiganan cream 0.8%). The Company was formed on January 14, 2010. On October 25, 2016, the Company announced that its lead and sole product candidate, Locilex®, failed to meet the primary clinical endpoint or secondary endpoints in its OneStep-1 and OneStep-2 Phase 3 clinical trials. Dipexium’s scientific team has evaluated the data from the OneStep clinical trials but has found no clear signal that Locilex® would be a strong product candidate for other possible clinical indications. Accordingly, Dipexium has explored strategic alternatives with its professional advisors and entered into a Merger Agreement with PLx Pharma Inc. (“PLx”) on December 22, 2016 (the “Proposed Merger”), pursuant to which PLx is expected to take control over Dipexium and Dipexium’s stockholders are expected to maintain approximately 23.25 700,000 500,000 The Company has experienced net losses and negative cash flows from operations since inception and expects these conditions to continue for the foreseeable future. The Company has needed to raise capital from sales of its securities to sustain operations. In March 2014, the Company completed an initial public offering (“IPO”) of common stock with proceeds, net of issuance costs, of approximately $ 34.5 19.7 12.4 12.0 Under the proposed merger, the combined company will initially be focused on completion of manufacturing scale-up and label finalization for the previously conditionally approved AspertecTM 325 mg. aspirin dosage form thereby satisfying the open conditional items, and filing of a supplemental new drug application (sNDA) for Aspertec 81 mg. maintenance dose form. Aspertec is being developed to provide high-risk cardiovascular and neurology patients with more reliable and predictable antiplatelet efficacy as compared to enteric coated aspirin while also reducing the adverse gastric events common in an acute setting. PLx stockholders will receive newly issued shares of common stock of Dipexium in connection with the Proposed Merger contemplated by the Merger Agreement. Upon the closing of the Proposed Merger, existing PLx stockholders are expected to own 76.75 23.25 The Company is subject to risks common to companies in the biopharmaceutical industry including, but not limited to, dependence on collaborative arrangements, development by the Company or its competitors of new technological innovations, dependence on key personnel, protection of proprietary technology, development of sales and marketing infrastructure and compliance with the Food and Drug Administration (“FDA”) and other governmental regulations and approval requirements. Unaudited Condensed Consolidated Interim Financial Data The accompanying interim condensed consolidated financial statements are unaudited. These unaudited interim condensed consolidated financial statements have been prepared in accordance with the rules and regulations of the United States Securities and Exchange Commission (“SEC”) for interim financial information. Accordingly, they do not include all the information and footnotes required by Generally Accepted Accounting Principles (“GAAP”) for complete financial statements. These unaudited interim condensed consolidated financial statements should be read in conjunction with the audited financial statements and accompanying notes for the year ended December 31, 2016. The unaudited interim condensed consolidated financial statements have been prepared on the same basis as the annual financial statements included in the Company’s Annual Report for the year ended December 31, 2016, and, in the opinion of management, reflect all the adjustments (consisting of normal recurring adjustments) necessary to state fairly the Company’s financial position as of March 31, 2017, the results of operations for the three months ended March 31, 2017 and 2016, the changes in shareholders’ equity for the three months ended March 31, 2017, and cash flows for the three months ended March 31, 2017 and 2016. The December 31, 2016 balance sheet included herein was derived from the audited financial statements, but may not include all disclosures required by GAAP for complete financial statements. The Company’s condensed consolidated financial statements include the accounts of the parent, Dipexium Pharmaceuticals, Inc., and Dipexium Pharmaceuticals Ireland, Limited, a wholly owned subsidiary. All significant intercompany accounts and transactions have been eliminated in consolidation. The preparation of financial statements in conformity with GAAP requires management 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 expenses during the reporting period. Actual results could differ from those estimates. The Company maintains its cash balance in one financial institution. The balance is insured up to the maximum allowable by the Federal Deposit Insurance Company (“FDIC”). The Company has not experienced any losses in such accounts and does not believe it is exposed to any significant risk of loss on cash. At times, the cash balance may exceed the maximum limit of the FDIC. The Company has a note receivable from an advance to PLx. Accrued interest on the note is included as a part of interest income and as interest receivable In accordance with Accounting Standards Codification (“ASC”) 730, Accounting for Research and Development Costs 14,688 3,583,667 Although the Company manages the conduct of its clinical trials, it relies on third parties to conduct its clinical and preclinical studies and to provide services, including data management, statistical analysis and electronic compilation for clinical trials, as well as for the manufacture of clinical trial supplies. At the end of each reporting period, the Company compares the payments made to each service provider to the estimated progress towards completion of the related project. Factors that are considered in preparing these estimates include the number of subjects enrolled in studies, milestones achieved and other criteria related to the efforts of the vendors. These estimates are subject to change as additional information becomes available. Depending on the timing of payments to vendors and estimated services provided, the Company records net prepaid or accrued expenses related to these costs. The Company accounts for the cost of services performed by officers and directors received in exchange for an award of Company membership interests, common stock, or stock options, based on the grant-date fair value of the award. In accordance with ASC 718, Stock Compensation The Company accounts for the cost of services performed by vendors in exchange for an award of common stock of the Company based on the grant-date fair value of the award or fair value of the services rendered, whichever is more readily determinable and adjusted to fair value at each reporting date. Such fair value is measured as of the earlier of the date the other party becomes committed to provide goods or services or the date performance by the other party is complete. The Company recognizes the expense in the same period and in the same manner as if the Company had paid cash for the services. The condensed consolidated financial statements are presented in U.S. Dollars (“USD”), the reporting currency of the Company. The functional currency for the Company’s subsidiary located in Ireland is the USD. Transactions denominated in Euros were translated to USD at rates which approximate those in effect on transaction dates. Monetary assets and liabilities denominated in foreign currencies at March 31, 2017 were translated at the exchange rate in effect as of those dates. Nonmonetary assets, liabilities, and shareholders’ equity are translated at the appropriate historical rates. The Company has intercompany loans between the parent company, Dipexium Pharmaceuticals, Inc., based in New York, NY, and its wholly owned subsidiary, Dipexium Pharmaceuticals Ireland, Limited, based in Ireland. The intercompany loans outstanding are not expected to be repaid in the foreseeable future. The Company recognizes deferred tax assets and liabilities for temporary differences between the financial reporting basis and the tax basis of the Company’s assets and liabilities and the expected benefits of net operating loss carryforwards. The impact of changes in tax rates and laws on deferred taxes, if any, applied during the years in which temporary differences are expected to be settled, is reflected in the financial statements in the period of enactment. The measurement of deferred tax assets is reduced, if necessary, if, based on weight of the evidence, it is more likely than not that some, or all, of the deferred tax assets will not be realized. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the period that such tax rate changes are enacted. The Company had no material amounts recorded for uncertain tax positions, interest or penalties in the accompanying financial statements. The Company currently estimates an annual effective tax rate of 0% as the Company incurred losses for the year ended December 31, 2016 and for the three months ended March 31, 2017, respectively, for both financial statement and tax purposes. Therefore, no Federal or state income tax expense has been recorded in the financial statements for the year ended December 31, 2016 and for the three months ended March 31, 2017, respectively. Based on the Company’s history of generating operating losses and its anticipation of operating losses continuing in the foreseeable future, the Company has determined that it is more likely than not that the tax benefits from these net operating losses would not be realized and a full valuation allowance against all deferred tax assets has been recorded at March 31, 2017 and December 31, 2016, respectively. In the event the Company becomes profitable for a period of two or more years, with future expectations at that time of profitability for future years prior to any significant change in its equity capitalization, the Company would have an opportunity to realize benefit from the deferred tax asset at such time in the future.
