Certain information and footnote disclosures normally included in the financial statements prepared in accordance with accounting principles generally accepted in the United States ("U.S. GAAP") may have been condensed or omitted pursuant to SEC rules and regulations, although the Company believes that the disclosures are adequate to make their presentation not misleading. In the Company's opinion, all adjustments, consisting of only normal and recurring items, necessary for a fair presentation of the results of operations for the three and nine months ended September 30, 2018 and 2017 have been included. The results of operations for these periods are not necessarily indicative of results that might be expected for the full year ending December 31, 2018.
