The accompanying unaudited statements have been prepared in accordance with U.S. generally accepted accounting principles for interim financial information. Accordingly, they do not include all of the information and footnotes required by U.S. generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments, consisting of normal recurring accruals, considered necessary for a fair presentation have been included.

Astronics Corporation (“Astronics” or the “Company”) is a leading provider of advanced technologies to the global aerospace, defense, electronics and semiconductor industries. Our products and services include advanced, high-performance electrical power generation, distribution and motion systems, lighting and safety systems, avionics products, systems and certification, aircraft structures and automated test systems.

We have operations in the United States (“U.S.”), Canada and France. We design and build our products through our wholly owned subsidiaries Astronics Advanced Electronic Systems Corp. (“AES”); Astronics AeroSat Corporation (“AeroSat”); Armstrong Aerospace, Inc. (“Armstrong”); Astronics Test Systems, Inc. (“ATS”); Ballard Technology, Inc. (“Ballard”); Astronics Connectivity Systems and Certification Corp. (“CSC”); Astronics Custom Control Concepts Inc. (“CCC”); Astronics DME LLC (“DME”); Luminescent Systems, Inc. (“LSI”); Luminescent Systems Canada, Inc. (“LSI Canada”); Max-Viz, Inc. (“Max-Viz”); Peco, Inc. (“Peco”); and PGA Electronic s.a. (“PGA”).

On April 3, 2017, Astronics Custom Control Concepts Inc., a wholly owned subsidiary of the Company acquired substantially all the assets and certain liabilities of Custom Control Concepts LLC, located in Kent, Washington. CCC is a provider of cabin management and in-flight entertainment systems for a range of aircraft. CCC is included in our Aerospace segment.

On December 1, 2017, Astronics acquired substantially all of the assets of Telefonix Inc. and a related company, Product Development Technologies, LLC and its subsidiaries, to become CSC, primarily located in Waukegan and Lake Zurich, Illinois. CSC designs and manufactures advanced in-flight entertainment and connectivity equipment, and provides industry leading design consultancy services for the global aerospace industry. CSC is included in our Aerospace Segment.

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 development 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 $28.9 million and $22.9 million for the three months ended March 31, 2018 and April 1, 2017, 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 31, 2018 and April 1, 2017.

The Company may, from time to time, incur costs in excess of the amounts required for existing contracts. If it is determined the costs are probable of recovery from future orders, the precontract costs incurred are capitalized, excluding start-up costs which are expensed as incurred. Capitalized precontract costs are included in Inventories in the accompanying Consolidated Balance Sheets. Should future orders not materialize or it is determined the costs are no longer probable of recovery, the capitalized costs are written off. Included in inventories at March 31, 2018 are capitalized precontract costs of $8.4 million.

In May 2014, the FASB issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”), that, together with several subsequent updates, outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance. ASU 2014-09 is based on the principle that an entity should recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 also provides for enhanced disclosure requirements surrounding revenue recognition.

Prior to the adoption of ASU 2014-09, revenue on a significant portion of our contracts had been recognized at the time of shipment of goods, transfer of title and customer acceptance, as required. Our revenue transactions generally consist of a single performance obligation to transfer promised goods and are not accounted for under industry-specific guidance. We have retained much of the same accounting treatment used to recognize revenue under the prior standard. However, the adoption of ASU 2014-09 required us to accelerate the recognition of revenue as compared to the prior standard, for certain customers, in cases where we produce products unique to those customers; and for which we would have an enforceable right of payment, inclusive of profit, for production completed to date.

We adopted ASU 2014-09 on January 1, 2018 using the modified retrospective method, which required the recognition of the cumulative effect of the transition as an adjustment to retained earnings. The Company elected to apply the standard only to open contracts as of January 1, 2018. Based on the application of the changes described above, we recognized a transition adjustment of $3.3 million, net of tax effects, which increased our January 1, 2018 retained earnings. Based on our existing operations, ASU 2014-09 is not expected to have a material impact to net earnings for the year ended December 31, 2018. Refer to Note 2 for additional information.

During the first quarter of 2018, the Company early-adopted ASU No. 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, which allows for a reclassification from accumulated other comprehensive income (loss) to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act. The Company applied the guidance as of the beginning of the period of adoption and reclassified approximately $1.4 million from accumulated other comprehensive loss to retained earnings due to the change in federal corporate tax rate.

In February 2016, the FASB issued ASU No. 2016 - 02, Leases. The new standard is effective for reporting periods beginning after December 15, 2018. Early adoption is permitted. The standard will require lessees to report most leases as assets and liabilities on the balance sheet, while lessor accounting will remain substantially unchanged. The standard requires a modified retrospective transition approach for existing leases, whereby the new rules will be applied to the earliest year presented. The Company is currently evaluating the impact of ASU 2016-02 on our financial statements.

In October 2016, the FASB issued ASU No. 2016-16, Income Taxes (Topic 740): Intra-Entity Transfer of Assets Other Than Inventory, which requires entities to recognize income tax consequences of intra-entity transfers of assets, other than inventory, when the transfer occurs rather than when the asset is sold to a third party as is the case under current GAAP. The Company adopted ASU 2016-16 effective January 1, 2018, and such adoption did not have a material impact on the consolidated financial statements.

In January 2017, the FASB issued ASU No. 2017-01, Clarifying the Definition of a Business, which narrows the existing definition of a business and provides a framework for evaluating whether a transaction should be accounted for as an acquisition (or disposal) of assets or a business. The ASU requires an entity to evaluate if substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets; if so, the set of transferred assets and activities (collectively, the set) is not a business. To be considered a business, the set would need to

include an input and a substantive process that together significantly contribute to the ability to create outputs. The standard also narrows the definition of outputs. The definition of a business affects areas of accounting such as acquisitions, disposals and goodwill. Under the new guidance, fewer acquired sets are expected to be considered businesses. The Company adopted ASU 2017-01 effective January 1, 2018. The Company will apply this guidance to applicable transactions after the adoption date on a prospective basis. No applicable transactions have occurred as of March 31, 2018.

In March 2017, the FASB issued ASU No. 2017-07, Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. This ASU changes how employers that sponsor defined benefit pension and/or other postretirement benefit plans present the net periodic benefit cost in the income statement. This ASU was adopted as of January 1, 2018 on a retrospective basis. Under the new standard, only the service cost component of net periodic benefit cost would be included in operating expenses. All other net periodic benefit costs components (such as interest cost, prior service cost amortization and actuarial gain/loss amortization) would be reported outside of operating income. These include components totaling $0.5 million and $0.4 million for the periods ended March 31, 2018 and April 1, 2017, respectively, that no longer are included within Selling, General and Administrative Expenses and instead are reported outside of income from operations, within Other Expense, Net of Other Income in our Consolidated Statements of Operations.

In May 2017, the FASB issued ASU No. 2017-09, Scope of Modification Accounting, that clarifies when changes to the terms or conditions of a share-based payment award must be accounted for as a modification. The general model for accounting for modifications of share-based payment awards is to record the incremental value arising from the changes as additional compensation cost. Under the new standard, fewer changes to the terms of an award would require accounting under this modification model. This ASU was adopted as of January 1, 2018. As the Company has not made changes to the terms or conditions of its issued share-based payment awards, this ASU had no impact on our consolidated results of operations and financial condition.

Payment terms and conditions vary by contract, although terms generally include a requirement of payment within a range from 30 to 60 days, or in certain cases, up-front deposits. In circumstances where the timing of revenue recognition differs from the timing of invoicing, the Company has determined that the Company's contracts generally do not include a significant financing component. Taxes collected from customers, which are subsequently remitted to governmental authorities, are excluded from sales.

The Company recognizes an asset for the incremental, material costs of obtaining a contract with a customer if the Company expects the benefit of those costs to be longer than one year. As of March 31, 2018, the Company does not have such incremental, material costs on any open contracts with an original expected duration of greater than one year, and therefore, we expense such costs as incurred. These incremental costs include, but are not limited to, sales commissions incurred to obtain a contract with a customer.

A performance obligation is a promise in a contract to transfer a distinct good or service to the customer, and is the unit of account. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied. The majority of our contracts have a single performance obligation as the promise to transfer the individual goods or services is not separately identifiable from other promises in the contracts and is, therefore, not distinct. Promised goods or services that are immaterial in the context of the contract are not separately assessed as performance obligations.

Some of our contracts have multiple performance obligations, most commonly due to the contract covering multiple phases of the product lifecycle (development, production, maintenance and support). For contracts with multiple performance obligations, we allocate the contract’s transaction price to each performance obligation using our best estimate of the standalone selling price of each distinct good or service in the contract. The primary method used to estimate standalone selling price is the expected cost plus a margin approach, under which we forecast our expected costs of satisfying a performance obligation and then add an appropriate margin for that distinct good or service. Shipping and handling activities that occur after the customer has obtained control of the good are considered fulfillment activities, not performance obligations.

Some of our contracts offer price discounts or free units after a specified volume has been purchased. The Company evaluates these options to determine whether they provide a material right to the customer, or represent a separate performance obligation. If the option provides a material right to the customer, revenue is recognized when those future goods or services are transferred or when the option expires.

Contract modifications are routine in the performance of our contracts. Contracts are often modified to account for changes in contract specifications or requirements. In most instances, contract modifications are for goods or services that are not distinct, and, therefore, are accounted for as part of the existing contract. The aggregate effect of all modifications as of the period beginning January 1, 2018 has been reflected when identifying the satisfied and unsatisfied performance obligations, determining the transaction price and allocating the transaction price. Contracts modified prior to January 1, 2018 have not been retrospectively restated.

The majority of the Company’s revenue from contracts with customers is recognized when the customer obtains control of the promised product, which is generally upon delivery and acceptance by the customer. These contracts may provide credits or incentives, which are accounted for as variable consideration. Variable consideration is estimated at the most likely amount to predict the consideration to which the Company will be entitled, and only to the extent it is probable that a subsequent change in estimate will not result in a significant revenue reversal when estimating the amount of revenue to recognize. Variable consideration is treated as a change to the sales transaction price and based largely on an assessment of all information (i.e., historical, current and forecasted) that is reasonably available to the Company, and estimated at contract inception and updated at the end of each reporting period as additional information becomes available. Most of our contracts do not contain rights to return product; where this right does exist, it is evaluated as possible variable consideration.

For contracts with customers in which the Company satisfies a promise to the customer to provide a product that has no alternative use to the Company and the Company has enforceable rights to payment for progress completed to date inclusive of profit, the Company satisfies the performance obligation and recognizes revenue over time, using costs incurred to date relative to total estimated costs at completion to measure progress toward satisfying our performance obligations. Incurred cost represents work performed, which corresponds with, and thereby best depicts, the transfer of control to the customer. Contract costs include labor, material and overhead.

The Company also recognizes revenue from service contracts (including service-type warranties) over time. The Company recognizes revenue over time during the term of the agreement as the customer is simultaneously receiving and consuming the benefits provided throughout the Company’s performance. Therefore, due to control transferring over time, the Company recognizes revenue on a straight-line basis throughout the contract period.

Costs in excess of billings includes unbilled amounts resulting from revenues under contracts with customers that are satisfied over time and when the cost-to-cost measurement method of revenue recognition is utilized and revenue recognized exceeds the amount billed to the customer, and right to payment is not just subject to the passage of time. Amounts may not exceed their net realizable value. Costs in excess of billings are classified as current assets, within Accounts Receivable, Net of Allowance for Doubtful Accounts on our Consolidated Balance Sheet.

Billings in excess of cost includes billings in excess of revenue recognized as well as deferred revenue, which includes advanced payments, up-front payments, and progress billing payments. Billings in excess of cost are classified as current liabilities, reported in our Consolidated Balance Sheet within Customer Advance Payments and Deferred Revenue. To determine the revenue recognized in the period from the beginning balance of billings in excess of cost, the contract liability as of the beginning of the period is recognized as revenue on a contract-by-contract basis when the Company incurs costs to satisfy the performance obligation related to the individual contract. Once the beginning contract liability balance for an individual contract has been fully recognized as revenue, any additional payments received in the period are recognized as revenue once the related costs have been incurred.

The Company's contract assets and contract liabilities consist of costs in excess of billings and billings in excess of cost, respectively. The following table presents the beginning and ending balances of contract assets and contract liabilities during the three months ended March 31, 2018 (in thousands):

The Company's Fourth Amended and Restated Credit Agreement (the “Original Facility”) provided for a $350 million revolving credit line with the option to increase the line by up to $150 million. The maturity date of the Original Facility was January 13, 2021. On February 16, 2018, the Company modified and extended the Original Facility by entering into the Fifth Amended and Restated Credit Agreement (the “Agreement”), which provides for a $500 million revolving credit line with the option to increase the line by up to $150 million. A new lender was added to the facility as well. The outstanding balance of the Original Facility was rolled into the Agreement on the date of closing. The maturity date of the loans under the Agreement is February 16, 2023. At March 31, 2018, there was $267.0 million outstanding on the revolving credit facility and there remains $231.9 million available, net of outstanding letters of credit. The credit facility allocates up to $20 million of the $500 million revolving credit line for the issuance of letters of credit, including certain existing letters of credit. At March 31, 2018, outstanding letters of credit totaled $1.1 million.

The maximum permitted leverage ratio of funded debt to Adjusted EBITDA (as defined in the Agreement) is 3.75 to 1, increasing to 4.50 to 1 for up to four fiscal quarters following the closing of an acquisition permitted under the Agreement, subject to limtations. The Company’s leverage ratio was 3.19 to 1 at March 31, 2018. The Company will pay interest on the unpaid principal amount of the facility at a rate equal to one-, three- or six-month LIBOR plus between 1.00% and 1.50% based upon the Company’s leverage ratio. The Company will also pay a commitment fee to the lenders in an amount equal to between 0.10% and 0.20% on the undrawn portion of the credit facility, based upon the Company’s leverage ratio.

In the event of voluntary or involuntary bankruptcy of the Company or any subsidiary, all unpaid principal and other amounts owing under the Agreement automatically become due and payable. Other events of default, such as failure to make payments as they become due and breach of financial and other covenants, change of control, judgments over a certain amount, and cross default under other agreements give the Agent the option to declare all such amounts immediately due and payable.

In the ordinary course of business, the Company warrants its products against defects in design, materials and workmanship typically over periods ranging from 12 to 60 months. The Company determines warranty reserves needed by product line based on experience and current facts and circumstances. Activity in the warranty accrual is summarized as follows:

On December 22, 2017, the President of the United States signed into law the Tax Cuts and Jobs Act (the “Act”). The legislation significantly changed U.S. tax law by, among other things, lowering corporate income tax rates, implementing a territorial tax system and imposing a repatriation tax on deemed repatriated earnings of foreign subsidiaries. The Act permanently reduced the U.S. corporate income tax rate from a maximum of 35% to a 21% rate, effective January 1, 2018.

While the Act provides for a territorial tax system, beginning in 2018, it includes the foreign-derived intangible income (“FDII”) and global intangible low-taxed income (“GILTI”) provisions. The Company elected to account for GILTI tax in the period in which it is incurred. The GILTI provisions require the Company to include in its U.S. income tax return foreign subsidiary earnings in excess of an allowable return on the foreign subsidiary’s tangible assets. The GILTI tax expense resulted from required allocations of interest expense to the GILTI income, which created a U.S. foreign tax credit limitation. The FDII provisions allow for a deduction equal to a percentage of the foreign-derived intangible income of a domestic corporation. As a result of these provisions, net, the Company’s effective tax rate decreased approximately 0.5% for the three months ended March 31, 2018.

On December 22, 2017, the SEC staff issued Staff Accounting Bulletin No. 118 (“SAB 118”) to address the application of GAAP in situations when a registrant does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the Act. The Company recognized provisional tax impacts related to the deemed repatriated earnings and the revaluation of deferred tax assets and liabilities in its consolidated financial statements for the year ended December 31, 2017. During the three months ended March 31, 2018, the Company did not make any adjustments to its provisional amounts included in its consolidated financial statements for the year ended December 31, 2017. The company is still obtaining and analyzing historical records and finalizing its calculation of these provisional amounts. The accounting is expected to be completed in the fourth quarter of 2018 after the 2017 U.S. corporate income tax return is filed.

On February 24, 2016, the Company’s Board of Directors authorized the repurchase of up to $50 million of common stock (the “Buyback Program”). The Buyback Program allowed the Company to purchase shares of its common stock in accordance with applicable securities laws on the open market or through privately negotiated transactions. The Company has repurchased approximately 1,675,000 shares and has completed that program. On December 12, 2017, the Company’s Board of Directors authorized an additional repurchase of up to $50 million. No amounts have been repurchased under the new program as of March 31, 2018.

Stock options with exercise prices greater than the average market price of the underlying common shares are excluded from the computation of diluted earnings per share because they are out-of-the-money and the effect of their inclusion would be anti-dilutive. The number of common shares covered by out-of-the-money stock options were insignificant as of March 31, 2018.

Sales to these two customers represented 20% and 16% of consolidated sales for the three months ended March 31, 2018. Sales to these customers were in the Aerospace segment. Accounts receivable from these customers at March 31, 2018 was approximately $32.2 million. Sales to these two customers represented 24% and 18% of consolidated sales for the three months ended April 1, 2017.

The Company is subject to various legal proceedings, claims, and litigation arising in the ordinary course of business. While the outcome of these matters is currently not determinable, we do not expect these matters will have a material adverse effect on our business, financial position, results of operations, or cash flows. However, the results of these matters cannot be predicted with certainty. Should the Company fail to prevail in any legal matter or should several legal matters be resolved against the Company in the same reporting period, then the financial results of that particular reporting period could be materially adversely affected.

On December 29, 2010, Lufthansa Technik AG (“Lufthansa”) filed a Statement of Claim in the Regional State Court of Mannheim, Germany. Lufthansa’s claim asserts that our subsidiary, AES, sold, marketed, and brought into use in Germany a power supply system that infringes upon a German patent held by Lufthansa. Lufthansa sought an order requiring AES to stop selling and marketing the allegedly infringing power supply system, a recall of allegedly infringing products sold to commercial customers in Germany since November 26, 2003, and compensation for damages related to direct sales of the allegedly infringing power supply system in Germany (referred to as “direct sales”). The claim does not specify an estimate of damages and a related damages claim is being pursued by Lufthansa in separate court proceedings in an action filed in July 2017, as further discussed below.

AES to provide certain financial information regarding direct sales of the infringing product in Germany to enable Lufthansa to make an estimate of requested damages. Additionally, if Lufthansa provides the required bank guarantee specified in the decision, the Company may be required to offer a recall of products that are in the distribution channels in Germany. No such bank guarantee has been issued to date. As of March 31, 2018, there are no products subject to the order in the distribution channels in Germany.

The Company appealed to the Higher Regional Court of Karlsruhe. On November 15, 2016, the Court issued its ruling and upheld the lower court’s decision. The Company submitted a petition to grant AES leave for appeal to the German Federal Supreme Court. On April 18, 2018, the German Federal Supreme Court granted Astronics’ petition in part, namely with respect to the part concerning the amount of damages. We estimate that the German Federal Supreme Court will provide its ruling on this issue in late 2018 or in early 2019.

In July 2017, Lufthansa filed an action in the Regional State Court of Mannheim for payment of damages caused by the alleged patent infringement of AES, related to direct sales of the allegedly infringing product in Germany (associated with the original December 2010 action discussed above). In this action, which was served to AES on April 11, 2018, Lufthansa claims payment of approximately $6.2 million plus interest. According to AES's assessment, this claim is significantly higher than justified. We estimate AES’s potential exposure to be approximately $1 million to $3 million, and have recorded a reserve of $1 million associated with this matter which is management's best estimate of the probable exposure. Such amount is recorded within Other Accrued Expenses and Selling, General and Administrative Expenses in the accompanying financial statements as of and for the three month period ended March 31, 2018. An oral hearing has been scheduled on November 16, 2018. A first instance decision is in this matter is expected in early 2019.

On December 29, 2017, Lufthansa filed another infringement action against AES in the Regional State Court of Mannheim claiming that sales by AES to its international customers have infringed Lufthansa's patent if AES's customers later shipped the products to Germany (referred to as "indirect sales"). This action, therefore, addresses sales other than those covered by the action filed on December 29, 2010, discussed above. In this action, served on April 11, 2018, Lufthansa seeks an order obliging AES to provide information and accounting and a finding that AES owes damages for the attacked indirect sales. AES will vigorously defend against the action. No amount of claimed damages has been specified by Lufthansa and such amount is not quantifiable at this time. A first instance decision in this matter is expected in early 2019. As loss exposure is neither probable nor estimable at this time, the Company has not recorded any liability with respect to this litigation as of March 31, 2018.

In December 2017, Lufthansa filed patent infringement cases in the United Kingdom and in France against AES. AES has been served in the case in France, but not in the case in the United Kingdom. In those cases, Lufthansa accuses AES of manufacturing, using, selling and offering for sale a power supply system that infringes upon a Lufthansa patent in those respective countries. As loss exposure is neither probable nor estimable at this time, the Company has not recorded any liability with respect to these matters as of March 31, 2018.

On November 26, 2014, Lufthansa filed a complaint in the United States District for the Western District of Washington. Lufthansa’s complaint in that action alleges that AES manufactures, uses, sells and offers for sale a power supply system that infringes upon a U.S. patent held by Lufthansa. The patent at issue in the U.S. action is based on technology similar to that involved in the German action. On April 25, 2016, the Court issued its ruling on claim construction, holding that the sole independent claim in the patent is indefinite, rendering all claims in the patent indefinite. Based on this ruling, AES filed a motion for summary judgment on the grounds that the Court’s ruling that the patent is indefinite renders the patent invalid and unenforceable. On July 20, 2016, the U.S. District Court granted the motion for summary judgment and issued an order dismissing all claims against AES with prejudice.

Lufthansa appealed the District Court's decision to the United States Court of Appeals for the Federal Circuit. On October 19, 2017, the Federal Circuit affirmed the district court’s decision, holding that the sole independent claim of the patent is indefinite, rending all claims on the patent indefinite. Lufthansa did not file a petition for en banc rehearing or petition the U.S. Supreme Court for a writ of certiorari. Therefore, there is no longer a risk of exposure from that lawsuit.

Below are the sales and operating profit by segment for the three months ended March 31, 2018 and April 1, 2017 and a reconciliation of segment operating profit to income before income taxes. Operating profit is net sales less cost of products sold and other operating expenses excluding interest and corporate expenses. Cost of products sold and other operating expenses are directly identifiable to the respective segment.

A fair value measurement assumes that the transaction to sell an asset or transfer a liability occurs in the principal market for the asset or liability or, in the absence of a principal market, the most advantageous market for the asset or liability. Fair value is based upon an exit price model. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and involves consideration of factors specific to the asset or liability.

The Company estimates the fair value of reporting units, utilizing unobservable Level 3 inputs. Level 3 inputs require significant management judgment due to the absence of quoted market prices or observable inputs for assets of a similar nature. The Company utilizes a discounted cash flow analysis to estimate the fair value of reporting units utilizing unobservable inputs. The fair value measurement of the reporting unit under the step-one and step-two analysis of the quantitative goodwill impairment test are classified as Level 3 inputs.

Intangible assets that are amortized are evaluated for recoverability whenever adverse effects or changes in circumstances indicate that the carrying value may not be recoverable. The recoverability test consists of comparing the undiscounted projected cash flows with the carrying amount. Should the carrying amount exceed undiscounted projected cash flows, an impairment loss would be recognized to the extent the carrying amount exceeds fair value. For the Company’s indefinite-lived intangible asset, the impairment test consists of comparing the fair value, determined using the relief from royalty method, with its carrying amount. An impairment loss would be recognized for the carrying amount in excess of its fair value.

Due to their short-term nature, the carrying value of cash and equivalents, accounts receivable, accounts payable, and notes payable approximate fair value. The carrying value of the Company’s variable rate long-term debt instruments also approximates fair value due to the variable rate feature of these instruments. As of March 31, 2018, the Company concluded that no indicators of impairment relating to intangible assets or goodwill existed and an interim test was not performed.

On April 3, 2017, Astronics Custom Control Concepts Inc., a wholly owned subsidiary of the Company, acquired substantially all the assets and certain liabilities of Custom Control Concepts LLC (“CCC”), located in Kent, Washington. CCC is a provider of cabin management and in-flight entertainment systems for a range of aircraft. The total consideration for the transaction was approximately $10.2 million, net of $0.5 million in cash acquired. All of the goodwill and purchased intangible assets are expected to be deductible for tax purposes over 15 years. The purchase price allocation for this acquisition has been finalized. CCC is included in our Aerospace segment.

On December 1, 2017, Astronics acquired substantially all of the assets of Telefonix Inc. and a related company, Product Development Technologies, LLC and its subsidiaries, to become Astronics Connectivity Systems and Certifications Corp. ("CSC"), primarily located in Waukegan and Lake Zurich, Illinois. CSC designs and manufactures advanced in-flight entertainment and connectivity equipment, and provides industry-leading design consultancy services for the global aerospace industry. The total consideration for the transaction was approximately $103.8 million, net of $0.2 million in cash acquired. All of the goodwill and purchased intangible assets are expected to be deductible for tax purposes over 15 years. CSC is included in our Aerospace Segment. The purchase price allocation for this acquisition has not yet been finalized.

The following summary, prepared on a pro forma basis, combines the consolidated results of operations of the Company with those of CSC as if the acquisition took place on January 1, 2017. The pro forma consolidated results include the impact of certain adjustments, including increased interest expense on acquisition debt, amortization of purchased intangible assets and income taxes.

Consolidated sales were up $26.7 million from the same period last year. Aerospace segment sales of $164.6 million were up $27.8 million and Test Systems segment sales of $14.5 million were down $1.1 million. Organic revenue was $154.0 million, up 1% compared with the same prior year period. The 2018 first quarter included $25.1 million in sales from the Acquired Businesses all in the Aerospace segment.

Consolidated cost of products sold was $141.9 million in the first quarter of 2018 compared with $114.1 million in the first quarter of 2017. Consolidated cost of products sold in the first quarter of 2018 increased due to higher sales, as well as several expenses that are expected to decrease or not recur through the remainder of 2018, including $1.3 million in expense related to the fair value step-up of inventory from the Acquired Businesses, which is now fully expensed. Another factor impacting cost of products sold in the quarter was a program charge of $2.1 million recognized due to the revision of estimated costs to complete a long-term contract assumed with the acquisition of the CCC business. Cost of products sold was impacted as well by the change in product mix, higher organic Engineering and Development ("E&D") costs and market pricing pressures primarily relating to cabin power, which increased costs of products sold.

Organic E&D costs were $24.3 million in the quarter, compared with $22.9 million in last year’s first quarter. As a percent of organic sales, organic E&D costs were 15.8% and 15.0% in the first quarters of 2018 and 2017, respectively. The Acquired Businesses incurred E&D costs of $4.6 million in the first quarter, which equates to 18.3% of acquired revenue.

Selling, general and administrative (“SG&A”) expenses were up $9.1 million to $30.5 million, or 17.0% of sales, in the first quarter of 2018 compared with $21.4 million, or 14.0% of sales, in the same period last year. Acquired Businesses contributed $7.1 million to SG&A, including $3.4 million of intangible asset amortization expense. Also contributing to higher SG&A was a $1.0 million litigation reserve recorded during the quarter for an ongoing matter. Corporate expenses increased by $1.5 million due to increased headcount, legal and accounting costs.

The effective tax rate for the quarter was 16.1%, compared with 25.2% in the first quarter of 2017. The 2018 first quarter tax rate was favorably impacted by the decrease in the Federal statutory tax rate partially offset by the elimination of the domestic production activities deduction resulting from the Tax Cuts and Jobs Act.

Operating profit, as presented below, is sales less cost of products sold and other operating expenses, excluding interest expense and other corporate expenses. Cost of products sold and other operating expenses are directly identifiable to the respective segment. Operating profit is reconciled to earnings before income taxes in Note 16 of the Notes to Consolidated Condensed Financial Statements included in this report.

Avionics sales were up $23.9 million, due to the addition of the Acquired Businesses, which contributed $22.5 million, coupled with an organic increase in antenna sales. System Certification sales increased by $2.6 million on higher project activity. Sales of other products were up $2.4 million, due primarily to the Acquired Businesses. These increases were offset by a decrease in Lighting & Safety sales of $1.0 million.

Aerospace operating profit for the first quarter of 2018 was $13.1 million, or 8.0% of sales, compared with $19.8 million, or 14.4% of sales, in the same period last year. Organic Aerospace E&D costs were $21.3 million compared with $20.3 million in the same period last year. The Acquired Businesses incurred E&D costs of $4.6 million during the quarter.

Aerospace operating profit was negatively impacted by several expenses that are expected to decrease or not recur through the remainder of 2018. As is typical during the first few quarters following an acquisition, non-cash costs were higher than what is expected over the long-term, as short-lived intangible assets are amortized and the fair value step-up costs relating to the acquired inventory is expensed. Intangible asset amortization expense for the Acquired Businesses was $3.4 million in the first quarter and fair value inventory step-up expense was $1.3 million. The inventory step-up was fully expensed in the quarter and intangible asset amortization expense related to the Acquired Businesses is expected to decline to $2.2 million in the second quarter and settle at a run rate of $1.6 million beginning in the third quarter of this year.

Aerospace orders in the first quarter of 2018 were up 47% to $180.9 million compared with the prior year period, and up 1% compared with the trailing fourth quarter of 2017. The book-to-bill ratio was 1.10:1 for the quarter. Backlog was $306.0 million at the end of the first quarter of 2018, up from $298.6 million at December 31, 2017.

We expect 2018 sales for our Aerospace segment to be in the range of $650 million to $680 million. The Aerospace segment’s backlog at the end of the first quarter of 2018 was $306.0 million with approximately $281.0 million expected to be shipped over the remaining part of 2018 and $293.7 million is expected to ship over the next 12 months.

Sales in the first quarter of 2018 decreased approximately $1.1 million to $14.5 million compared with the same period in 2017, a decrease of 7.1%. The $2.4 million increase in sales to the Semiconductor market was offset by a $3.5 million decrease in sales to the Aerospace & Defense market when compared with the prior-year period.

We expect sales for the Test Systems segment for 2018 to be in the range of $115 million to $135 million. The Test Systems segment’s backlog at the end of the first quarter of 2018 was $92.6 million, with approximately $75.0 million expected to be shipped over the remaining part of 2018 and approximately $77.4 million scheduled to ship over the next 12 months.

Cash used by operating activities totaled $1.1 million for the first three months of 2018, as compared with $6.4 million in cash provided by operating activities during the same period in 2017. Cash flow from operating activities decreased compared with the same period of 2017 primarily due to the impact of lower net income and higher increases in net operating assets for the first three months of 2018 when compared with the first three months of 2017.

The primary financing activities in the first three months of 2018 related to net borrowings from our senior credit facility of $5.0 million and $0.5 million of costs incurred related to the execution of the Agreement in February 2018. The primary financing activities in the first three months of 2017 related to the net repayments of the senior facility and other debt of $6.7 million and $4.4 million in share repurchases.

On February 24, 2016, the Company’s Board of Directors authorized the repurchase of up to $50 million of common stock (the “Buyback Program”). The Buyback Program allowed the Company to purchase shares of its common stock in accordance with applicable securities laws on the open market or through privately negotiated transactions. The Company has repurchased approximately 1,675,000 shares and has completed that program. On December 12, 2017, the Company’s Board of Directors authorized an additional repurchase of up to $50 million of common stock. No amounts have been repurchased under the new program as of March 31, 2018.

The Company's Fourth Amended and Restated Credit Agreement (the “Original Facility”) provided for a $350 million revolving credit line with the option to increase the line by up to $150 million. The maturity date of the original facility was January 13, 2021. On February 16, 2018, the Company modified and extended the Original Facility by entering into the Fifth Amended and Restated Credit Agreement (the “Agreement”), which provides for a $500 million revolving credit line with the option to increase the line by up to $150 million. A new lender was added to the facility as well. The outstanding balance in the Original Facility were rolled into the Agreement on the date of closing. The maturity date of the loans under the Agreement is February 16, 2023. At March 31, 2018, there was $267.0 million outstanding on the revolving credit facility and there remains $231.9 million available, net of outstanding letters of credit. The credit facility allocates up to $20 million of the $500 million revolving credit line for the issuance of letters of credit, including certain existing letters of credit. At March 31, 2018, outstanding letters of credit totaled $1.1 million.

The maximum permitted leverage ratio of funded debt to Adjusted EBITDA (as defined in the Agreement) is 3.75 to 1, increasing to 4.50 to 1 for up to four fiscal quarters following the closing of an acquisition permitted under the Agreement, subject to limitations. The Company’s leverage ratio was 3.19 to 1 at March 31, 2018. The Company will pay interest on the unpaid principal amount of the facility at a rate equal to one-, three- or six-month LIBOR plus between 1.00% and 1.50% based upon the Company’s leverage ratio. The Company will also pay a commitment fee to the lenders in an amount equal to between 0.10% and 0.20% on the undrawn portion of the credit facility, based upon the Company’s leverage ratio.

The Company believes that there have been no material changes in the current year regarding the market risk information for its exposure to interest rate fluctuations. Although the majority of our sales, expenses and cash flows are transacted in U.S. dollars, we have exposure to changes in foreign currency exchange rates related to the Euro and the Canadian dollar. The Company believes that the impact of changes in foreign currency exchange rates in 2018 have not been significant.

The Company’s management, with the participation of the Company’s Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of the Company’s disclosure controls and procedures as of March 31, 2018. Based on that evaluation, the Company’s Chief Executive Officer and Chief Financial Officer concluded that the Company’s disclosure controls and procedures were effective as of March 31, 2018.

Effective January 1, 2018, we adopted ASU No. 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”). Although the adoption of ASU 2014-09 had an immaterial impact on our financial statements, we implemented certain changes to our related revenue recognition control activities, including the development of new policies, based on the five-step model provided in the revenue standard.

In February 2015, the Regional State Court of Mannheim, Germany rendered its decision that the patent was infringed. The judgment does not require AES to recall products that are already installed in aircraft or have been sold to other end users. On July 15, 2015, Lufthansa advised AES of their intention to enforce the accounting provisions of the decision, which required AES to provide certain financial information regarding direct sales of the infringing product in Germany to enable Lufthansa to make an estimate of requested damages. Additionally, if Lufthansa provides the required bank guarantee specified in the decision, the Company may be required to offer a recall of products that are in the distribution channels in Germany. No such bank guarantee has been issued to date. As of March 31, 2018, there are no products subject to the order in the distribution channels in Germany.

In addition to other information set forth in this report, you should carefully consider the factors discussed in Part 1, Item 1A. “Risk Factors,” in our Annual Report on Form 10-K for the year ended December 31, 2017, which could materially affect our business, financial condition or results of operations. The risks described in our Annual Report on Form 10-K are not the only risks facing us. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition and/or results of operations.
