In the opinion of management, all adjustments, consisting of normal recurring accruals, considered necessary for a fair presentation have been included.

Operating Results

The results of operations for any interim period are not necessarily indicative of results for the full year. Operating results for the three month period ended March 30, 2013 are not necessarily indicative of the results that may be expected for the year ending December 31, 2013.

Description of the Business

Astronics is a leading supplier of advanced, high-performance lighting systems, electrical power generation and distribution systems, avionics databus solutions, enhanced vision systems and aircraft safety systems for the global aerospace industry as well as test, training and simulation systems primarily for the military. We sell our products to airframe manufacturers (OEMs) in the commercial transport, business jet and military markets as well as FAA/Airport, OEM suppliers and aircraft operators around the world. The Company provides its products through its wholly owned subsidiaries Astronics Advanced Electronic Systems Corp. (“AES”), Ballard Technology, Inc. (“Ballard”), DME Corporation (“DME”), Luminescent Systems, Inc. (“LSI”), Luminescent Systems Canada, Inc. (“LSI Canada”) and Max-Viz Inc. (“Max-Viz”). On July 30, 2012 Astronics acquired by merger, 100% of the stock of Max-Viz, Inc. Max-Viz is a manufacturer of industry-leading enhanced vision systems for defense and commercial aerospace applications for the purpose of improving situational awareness. Max-Viz is part of our Aerospace segment.

The Company has two reportable segments, Aerospace and Test Systems. The Aerospace segment designs and manufactures products for the global aerospace industry. The Test Systems segment designs, manufactures and maintains communications and weapons test systems and training and simulation devices for military applications.

Principles of Consolidation

The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany transactions and balances have been eliminated. Acquisitions are accounted for under the purchase method and, accordingly, the operating results for the acquired companies are included in the consolidated statements of earnings from the respective dates of acquisition.

Revenue and Expense Recognition

In the Aerospace segment, revenue is recognized on the accrual basis at the time of shipment of goods and transfer of title. There are no significant contracts allowing for right of return.

In the Test Systems segment, revenue of approximately 27% and 40% for the three months ending March 30, 2013 and March 31, 2012 respectively, is recognized from long-term, fixed-price contracts using the percentage-of-completion method of accounting, measured by multiplying the estimated total contract value by the ratio of actual contract costs incurred to date to the estimated total contract costs. Substantially all long-term contracts are with U.S. government agencies and contractors thereto. The Company makes significant estimates involving its usage of percentage-of-completion accounting to recognize contract revenues. The Company periodically reviews contracts in process for estimates-to-completion, and revises estimated gross profit accordingly. While the Company believes its estimated gross profit on contracts in process is reasonable, unforeseen events and changes in circumstances can take place in a subsequent accounting period that may cause the Company to revise its estimated gross profit on one or more of its contracts in process. Accordingly, the ultimate gross profit realized upon completion of such contracts can vary significantly from estimated amounts between accounting periods. Revenue not recognized using the percentage-of-completion method is recognized at the time of shipment of goods and transfer of title.

Cost of Products Sold, Engineering and Development and Selling, General and Administrative Expenses

Cost of products sold includes the costs to manufacture products such as direct materials and labor and manufacturing overhead as well as all engineering and developmental costs. The Company is engaged in a variety of engineering and design activities as well as basic research and development activities directed to the substantial improvement or new application of the Company’s existing technologies. These costs are expensed when incurred and included in cost of products sold. Research and development, design and related engineering amounted to $12.8 million and $10.0 million for the three months ended March 30, 2013 and March 31, 2012 respectively. Selling, general and administrative expenses include costs primarily related to our sales and marketing departments and administrative departments. Interest expense is shown net of interest income. Interest income was insignificant for the three months ended March 30, 2013 and March 31, 2012.

Financial Instruments

The Company’s financial instruments consist primarily of cash and cash equivalents, accounts receivable, accounts payable, notes payable, long-term debt and interest rate swaps. The Company performs periodic credit evaluations of its customers’ financial condition and generally does not require collateral. The Company does not hold or issue financial instruments for trading purposes. Due to their short-term nature, the carrying values of cash and equivalents, accounts receivable, accounts payable, and notes payable, if any, approximate fair value. The carrying value of the Company’s variable rate long-term debt also approximates fair value due to the variable rate feature of these instruments. The Company’s interest rate swaps are recorded at fair value as described under Note 16—Fair Value and Note 17—Derivative Financial Instruments.

Derivatives

The accounting for changes in the fair value of derivatives depends on the intended use and resulting designation. The Company’s use of derivative instruments is limited to cash flow hedges for interest rate risk associated with long-term debt. Interest rate swaps are used to adjust the proportion of total debt that is subject to variable and fixed interest rates. The interest rate swaps are designated as hedges of the amount of future cash flows related to interest payments on variable-rate debt that, in combination with the interest payments on the debt, convert a portion of the variable-rate debt to fixed-rate debt. The Company records all derivatives on the balance sheet at fair value as described under Note 16—Fair Value and Note 17—Derivative Financial Instruments. The related gains or losses, to the extent the derivatives are effective as a hedge, are deferred in shareholders’ equity as a component of Accumulated Other Comprehensive Income (Loss) (AOCI) and reclassified into earnings at the time interest expense is recognized on the associated long-term debt. Any ineffectiveness is immediately recorded in the statement of operations.

Foreign Currency Translation

The Company accounts for its foreign currency translation in accordance with Accounting Standards Codification (“ASC”) Topic 830, Foreign Currency Translation. The aggregate transaction gain or loss included in operations was insignificant for the periods ending March 30, 2013 and March 31, 2012.

Loss contingencies

Loss contingencies may from time to time arise from situations such as claims and other legal actions. Loss contingencies are recorded as liabilities when it is probable that a liability has been incurred and the amount of the loss is reasonably estimable. Disclosure is required when there is a reasonable possibility that the ultimate loss will exceed the recorded provision. Contingent liabilities are often resolved over long time periods. In recording liabilities for probable losses, management is required to make estimates and judgments regarding the amount or range of the probable loss. Management continually assesses the adequacy of estimated loss contingencies and, if necessary, adjusts the amounts recorded as better information becomes known.

Accounting Pronouncements Adopted in 2013

On January 1, 2013, the Company adopted the new provisions of Accounting Standards Update (“ASU”) No. 2013-02 Comprehensive Income (Topic 220). The amendments in this ASU require the Company to provide information about the amounts reclassified out of accumulated other comprehensive income, by component. Other than requiring additional disclosures, the adoption of this amendment does not have a material impact on the Company’s financial statements.
