Condensed Consolidated Financial Statements	1. Condensed Consolidated Financial Statements The financial statements are presented in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and the rules and regulations of the Securities and Exchange Commission (the “SEC”) for quarterly reports on Form 10-Q and should be read in conjunction with the Company’s audited financial statements and notes thereto for the year ended December 31, 2016, included in the 2016 Annual Report on Form 10-K. All terms used but not defined elsewhere herein have the meaning ascribed to them in the Company’s 2016 Annual Report on Form 10-K filed on March 7, 2017. In the opinion of management, all adjustments (consisting of normal and recurring adjustments) considered necessary for a fair statement of the results of the interim periods presented have been included. The 2016 year-end condensed balance sheet data was derived from the audited financial statements but does not include all disclosures required by U.S. GAAP. The results of operations for the three and six months ended June 30, 2017 are not necessarily indicative of the results expected for the full year. Closing of Chapter 11 Case On April 12, 2016, the Company emerged from chapter 11 of the Bankruptcy Code when the Company's plan of reorganization (the “Plan”) became effective, and on December 22, 2016 the Company's chapter 11 case was closed by the Bankruptcy Court. Under the Plan, the Company fully paid all of its claims. The Company did not apply the provision of fresh start accounting as ownership of existing shares of the Company's common stock remained unaltered by the Plan. Prior to April, 12 2016, the effective date of the Plan, the Company was operating its business as a “debtor-in-possession”. The Company had filed on September 16, 2014 a voluntary petition for relief under chapter 11 of Title 11 of the United States Code (the “Bankruptcy Code”) in the United States Bankruptcy Court for the Southern District of New York (the “Bankruptcy Court”) chapter 11 Case Number 14-12623 (SHL). The chapter 11 case preserved the Company's ability to satisfy its commitments under the BARDA Contract (as defined in Note 3) and preserved its operations, which likely would have been jeopardized by the enforcement of a judgment stemming from the Company's litigation with PharmAthene, Inc. (“PharmAthene”) (see “PharmAthene Litigation” below). While operating as a debtor-in-possession under chapter 11, the Company pursued an appeal of the Delaware Court of Chancery Final Order and Judgment, without having to post a bond. PharmAthene Litigation On November 16, 2016, the Company satisfied the Outstanding Judgment (as defined in Note 11) owed to PharmAthene in connection with the Company's litigation with PharmAthene. In total, PharmAthene was paid $217.0 million in connection with the Outstanding Judgment. See Note 11 for additional details related to this litigation. Liquidity The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern and contemplate the realization of assets and the satisfaction of liabilities in the normal course of business. The Company is not entitled to receive any additional procurement-related payments under the current BARDA Contract (Note 3) until U.S. Food and Drug Administration (“FDA”) approval of TPOXX® has been achieved and until a cumulative 2.0 million courses of TPOXX® have been delivered to the U.S. Strategic National Stockpile (“Strategic Stockpile”). Upon meeting these requirements, the Company is entitled to a $41.0 million hold back payment under the BARDA Contract. Based on a targeted New Drug Application (“NDA”) filing for TPOXX® by the end of 2017, it is currently anticipated that the Company will be eligible to receive the $41.0 million hold back payment in the second half of 2018. In the event that the Company does not receive a substantial portion of the hold back payment, or other substantial cash inflows, by the end of the third quarter of 2018, then, based on currently forecasted operating costs, the Company will require additional sources of funding to continue operations and prevent an event of default under the Term Loan (Note 8). In this case, the Company would seek to increase cash liquidity by: raising proceeds through a financing, a new contract for TPOXX® or any other product, a sale of assets, or the modification of the existing BARDA Contract; significantly reducing its operating expenses; or modifying the terms of the Loan Agreement. There can be no assurance that the Company will cumulatively deliver 2.0 million courses of TPOXX® to the Strategic Stockpile, or that TPOXX® will receive FDA approval on a timely basis, if at all. Furthermore, there can be no assurance that the Company would be able to increase cash liquidity, if needed, through a financing, a new contract for TPOXX® or any other product, a sale of assets, the modification of the existing BARDA Contract, or a significant reduction of its operating expenses or operations, or that the lenders would agree to modify the Term Loan Agreement, if needed.
