| Financial Statement Presentation |
Financial Statement Presentation The condensed consolidated balance sheets and condensed consolidated statement of changes in stockholders’ equity as of March 31, 2018 and the related condensed consolidated statements of loss and comprehensive loss, and the condensed consolidated statements of cash flows for the periods ended March 31, 2018 and 2017 have been prepared by Company management. In the opinion of management, all adjustments (which include only normal recurring adjustments, except where noted) necessary to present fairly the financial position, results of operations, and cash flows at March 31, 2018 and 2017 and for the periods then ended have been made. Certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with generally accepted accounting principles in the United States of America have been condensed or omitted. We recommend these condensed consolidated financial statements be read in conjunction with the financial statements and notes thereto included in the Company’s December 31, 2017 Annual Report to Shareholders on Form 10-K. The results of operations for the period ended March 31, 2018 are not necessarily indicative of operating results for the entire year. The presentation of financial statements in conformity with generally accepted accounting principles 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 balance sheet date, and the reported amounts of revenues and expenses during the reporting period. The estimates and assumptions used in the accompanying condensed consolidated financial statements are based upon management’s evaluation of the relevant facts and circumstances as of the time of the financial statements. Actual results could differ from those estimates. Except to the extent updated or described below, the significant accounting policies set forth in Note 1 to the consolidated financial statements in the Company's Annual Report on Form 10-K for the year ended December 31, 2017, appropriately represent, in all material respects, the current status of accounting policies, and are incorporated herein by reference.
