(1) Nature of Business and Basis of Presentation

Our accompanying unaudited consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X.  Accordingly, they do not include all of the information and footnotes required by U.S. generally accepted accounting principles for complete financial statements.  In our opinion, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included.  Operating results for the three and nine months ended September 30, 2015 are not necessarily indicative of the results that may be expected for the fiscal year ending December 31, 2015.  For further information refer to the consolidated financial statements and footnotes thereto included in our 2014 Form 10-K.

The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires us 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 revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant estimates affecting the financial statements include accruals for contract disallowance reserves, recoverability of goodwill and intangible assets and earn-out obligations.

We have made the following additions to our significant accounting policies as a result of our Aviation Acquisition in January 2015 (see Note 2):

Our Aviation Group revenues are recognized upon the shipment or delivery of products to customers based on when title transfers to the customer. Sales returns and allowances are not significant.

Our Aviation Group inventories are stated at lower of cost or market. Our Aviation Group inventories primarily consist of corporate and regional jet aircraft engines and engine accessories and parts. Cost for purchased engines and parts is determined by the specific identification method. Included in inventory are related purchasing, overhaul labor, storage, and handling costs. We also purchase aircraft engines for disassembly to individual parts and components.
