The Company operates on a 52/53 week fiscal year with quarters ending on the Friday closest to the last day of the calendar quarter. For ease of presentation, March 31 and September 30 are utilized consistently throughout these financial statements and notes to represent the period end dates. The Company has one consolidated subsidiary with income attributable to a noncontrolling interest. The net income and comprehensive income attributable to the noncontrolling interest is insignificant. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America and with the instructions to Form 10-Q of the Securities and Exchange Commission. Certain information and footnote disclosures normally included in annual financial statements have been condensed or omitted. These financial statements should be read in conjunction with the Company's Annual Report on Form 10-K for the year ended September 30, 2015. In the opinion of management, the unaudited financial statements contain all adjustments, consisting of adjustments of a normal recurring nature, necessary to present fairly the financial position, results of operations and cash flows for the periods presented. The results of operations for the three and six months ended March 31, 2016 are not necessarily indicative of the results that may be expected for the full year. The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the amounts reported in the financial statements. Actual results could differ from those estimates and assumptions. As discussed in Note 4, Discontinued Operations and Divestitures, on March 10, 2015, the Company divested its Aerospace Systems Engineering and Support (ASES) business, which provides military aircraft integration and modifications, maintenance and logistics and support. As a result, the ASES business has been accounted for as a discontinued operation for all periods presented. |
