Notes to Condensed Consolidated Financial Statements (Unaudited)

Note 1. Summary of Significant Accounting Policies
Description of Business
We are a leading global provider of engineering and manufacturing services for high-performance products and high-cost-of failure applications used primarily in the aerospace and defense (“A&D”), industrial, medical and other industries (collectively, “Industrial”). Our operations are organized into two primary businesses: Electronic Systems segment and Structural Systems segment, each of which is a reportable operating segment. Electronic Systems designs, engineers and manufactures high-reliability electronic and electromechanical products used in worldwide technology-driven markets including A&D and Industrial end-use markets. Electronic Systems’ product offerings primarily range from prototype development to complex assemblies. Structural Systems designs, engineers and manufactures large, complex contoured aerostructure components and assemblies and supplies composite and metal bonded structures and assemblies. Structural Systems’ products are primarily used on commercial aircraft, military fixed-wing aircraft, and military and commercial rotary-wing aircraft. All reportable operating segments follow the same accounting principles.
Basis of Presentation
The unaudited condensed consolidated financial statements include the accounts of Ducommun Incorporated and its subsidiaries (“Ducommun,” the “Company,” “we,” “us” or “our”), after eliminating intercompany balances and transactions. The December 31, 20172018 condensed consolidated balance sheet data was derived from audited financial statements, but does not contain all disclosures required by accounting principles generally accepted in the United States of America (“GAAP”).
Our significant accounting policies were described in Part IV, Item 15(a)(1), “Note 1. Summary of Significant Accounting Policies” in our Annual Report on Form 10-K for the year ended December 31, 2017.2018. We followed the same accounting policies for interim reporting except for the change in our revenue recognitionlease accounting practices described below. The financial information included in this Quarterly Report on Form 10-Q should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2017.2018.
In the opinion of management, all adjustments, consisting of recurring accruals, have been made that are necessary to fairly state our condensed consolidated financial position, statements of income, comprehensive income and cash flows in accordance with GAAP for the periods covered by this Quarterly Report on Form 10-Q. The results of operations for the three and nine months ended September 29, 2018March 30, 2019 are not necessarily indicative of the results to be expected for the full year ending December 31, 2018.2019.
Our fiscal quarters typically end on the Saturday closest to the end of March, June and September for the first three fiscal quarters of each year, and ends on December 31 for our fourth fiscal quarter. As a result of using fiscal quarters for the first three quarters combined with leap years, our first and fourth fiscal quarters can range between 12 1/2 weeks to 13 1/2 weeks while the second and third fiscal quarters remain at a constant 13 weeks per fiscal quarter.
Certain reclassifications have been made to prior period amounts to conform to the current year’s presentation.
Changes in Accounting Policies
We adopted ASC 606, “Revenue from Contracts with Customers”Accounting Standards Codification (“ASC”) 842, “Leases” (“ASC 606”842”), on January 1, 2018.2019. As a result, we changed our accounting policy for revenue recognitionlease accounting as detailed below anddiscussed in Note 2, as well as other accounting policies as noted below.2.
We applied ASC 606842 using the modified retrospectiveadditional transition method (also known as the cumulative effect method) and therefore, recognized the cumulative effect of initially applying ASC 606842 as an adjustment to the opening condensed consolidated balance sheet at January 1, 2018.2019. Therefore, the comparative information has not been adjusted and continues to be reported under the previous revenue recognitionlease accounting standard, ASC 605, “Revenue Recognition”840, “Leases” (“ASC 605”840”). The details of the significant changes and quantitative impact of the changes are described below andin Note 2.
Use of Estimates
Certain amounts and disclosures included in the unaudited condensed consolidated financial statements require management to make estimates and judgments that affect the amounts of assets, liabilities (including forward loss reserves), revenues and expenses, and related disclosures of contingent assets and liabilities. These estimates are based on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for

making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates.

Earnings Per Share
Basic earnings per share are computed by dividing income available to common shareholders by the weighted-average number of common shares outstanding in each period. Diluted earnings per share is computed by dividing income available to common shareholders by the weighted-average number of common shares outstanding, plus any potentially dilutive shares that could be issued if exercised or converted into common stock in each period.
The net income and weighted-average common shares outstanding used to compute earnings per share were as follows:

Fair Value
Assets and liabilities that are measured, recorded or disclosed at fair value on a recurring basis are categorized using the fair value hierarchy. The fair value hierarchy has three levels based on the reliability of the inputs used to determine the fair value. Level 1, the highest level, refers to the values determined based on quoted prices in active markets for identical assets. Level 2 refers to fair values estimated using significant observable inputs. Level 3, the lowest level, includes fair values estimated using significant unobservable inputs.
We have money market funds and they are included as cash and cash equivalents. We also have interest rate cap hedge agreements and the fair value of the interest rate cap hedge agreements were determined using pricing models that use observable market inputs as of the balance sheet date, a Level 2 measurement. The interest rate cap hedge premium as of March 30, 2019 of $0.1 million is included as other current assets.
There were no transfers between Level 1, Level 2, or Level 3 financial instruments in the three months ended March 30, 2019.

Cash and Cash Equivalents
Cash equivalents consist of highly liquid instruments purchased with original maturities of three months or less. These assets are valued at cost, which approximates fair value, which we classify as Level 1. See Fair Value above.
Derivative Instruments
We recognize derivative instruments on our condensed consolidated balance sheets at their fair value. On the date that we enter into a derivative contract, we designate the derivative instrument as a fair value hedge, a cash flow hedge, a hedge of a net investment in a foreign operation, or a derivative instrument that will not be accounted for using hedge accounting methods. As of September 29, 2018,March 30, 2019, all of our derivative instruments were designated as cash flow hedges.
We record changes in the fair value of a derivative instrument that is highly effective and that is designated and qualifies as a cash flow hedge in other comprehensive income (loss), net of tax until our earnings are affected by the variability of cash flows of the underlying hedge. We record any hedge ineffectiveness and amounts excluded from effectiveness testing in current period earnings within interest expense. We report changes in the fair values of derivative instruments that are not designated or do not qualify for hedge accounting in current period earnings. We classify cash flows from derivative instruments in the condensed consolidated statements of cash flows in the same category as the item being hedged or on a basis consistent with the nature of the instrument. For the three months ended March 30, 2019, we recorded the changes in the fair value of the derivative instruments that were highly effective and that was designated and qualified as cash flow hedges in other comprehensive income (loss), net of tax, of $(0.1) million. Since a portion of our cash flow hedges mature on a quarterly basis, less than $(0.1) million of realized loss was recorded in the condensed consolidated statements of income for the three months ended March 30, 2019.
When we determine that a derivative instrument is not highly effective as a hedge, we discontinue hedge accounting prospectively. In all situations in which we discontinue hedge accounting and the derivative instrument remains outstanding, we will carry the derivative instrument at its fair value on our condensed consolidated balance sheets and recognize subsequent changes in its fair value in our current period earnings.
Inventories
Inventories are stated at the lower of cost or net realizable value with cost being determined using a moving average cost basis for raw materials and actual cost for work-in-process and finished goods. The majority of our inventory is charged to cost of sales as raw materials are placed into production and the related revenue is recognized. Inventoried costs include raw materials, outside processing, direct labor and allocated overhead, adjusted for any abnormal amounts of idle facility expense, freight, handling costs, and wasted materials (spoilage) incurred. We assess the inventory carrying value and reduce it, if necessary, to its net realizable value based on customer orders on hand, and internal demand forecasts using management’s best estimates given information currently available. As a result of adopting ASC 606 on January 1, 2018, where we utilized the modified retrospective method of adoption and we changed our revenue recognition for theThe majority of our revenue from point in time toare recognized over time, our inventory balance decreased significantly. Forhowever, for revenue contracts where revenue is recognized using the point in time method, inventory is not reduced until it is shipped or transfer of control to the customer has occurred. Our ending inventory consists of raw materials, work-in-process, and finished goods. See Note 2.
Production Cost of Contracts
Production cost of contracts includes non-recurring production costs, such as design and engineering costs, and tooling and other special-purpose machinery necessary to build parts as specified in a contract. Production costs of contracts are recorded to cost of sales using the over time revenue recognition model. We review the value of the production cost of contracts on a quarterly basis to ensure when added to the estimated cost to complete, the value is not greater than the estimated realizable value of the related contracts.
Accumulated Other Comprehensive Loss
Accumulated other comprehensive loss, as reflected on the condensed consolidated balance sheets under the equity section, was comprised of cumulative pension and retirement liability adjustments, net of tax, and change in net unrealized gains and losses on cash flow hedges, net of tax.
Provision for Estimated Losses on Contracts
We record provisions for the total anticipated losses on contracts, considering total estimated costs to complete the contract compared to total anticipated revenues, in the period in which such losses are identified. The provisions for estimated losses on contracts require us to make certain estimates and assumptions, including those with respect to the future revenue under a contract and the future cost to complete the contract. Our estimate of the future cost to complete a contract may include assumptions as to changes in manufacturing efficiency, operating and material costs, and our ability to resolve claims and

assertions with our customers. If any of these or other assumptions and estimates do not materialize in the future, we may be required to adjust the provisions for estimated losses on contracts. As a result of the adoption of ASC 606 on January 1, 2018,

the definition of a revenue contract with a customer for us now has changed and is typically defined as a customer purchase order, in certain scenarios, we may be required to recognize anticipated losses on contracts that would not have occurred under ASC 605. In addition,The provision for estimated losses on contracts are now included as part of contract liabilities on the condensed consolidated balance sheets.
Revenue Recognition
Our customers typically engage us to manufacture products based on designs and specifications provided by the end-use customer. This will require the building of tooling and manufacturing first article inspection products (prototypes) before volume manufacturing. Contracts with our customers generally include a termination for convenience clause.
We have a significant number of contracts that are started and completed within the same year, as well as contracts derived from long-term contractsagreements and programs that can span several years, as well as contracts that are started and completed within the same year.years. We recognize revenue under ASC 606, which utilizes a five-step model. Further, we utilized the modified retrospective method (also known as the cumulative effect method) of adoption of ASC 606. See Note 2.
The definition of a contract under ASC 606 for us is typically defined as a customer purchase order as this is when we achieve enforceable right to payment. The majority of our contracts are firm fixed-price contracts. The deliverables within a customer purchase order are analyzed to determine the number of performance obligations. In addition, at times, in order to achieve economies of scale and based on our customer’s forecasted demand, we may build in advance of receiving a purchase order from our customers.customers and in which case, we would not recognize revenue until we have received the customer purchase order.
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 under ASC 606. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, control is transferred and 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 fromare highly interrelated or met the other promises in the contracts and therefore, not distinct.series guidance. For contracts with multiple performance obligations, we allocate the contract 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 the 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.
The majority of our performance obligations are satisfied over time as work progresses. Typically, revenue is recognized over time using an input measure (i.e., costs incurred to date relative to total estimated costs at completion, also known as cost-to-cost plus reasonable profit) to measure progress. Our typical revenue contract is a firm fixed price contract, and the cost of raw materials could make up a significant amount of the total costs incurred. As such, we believe using the total costs incurred input method would be the most appropriate method. While the cost of raw materials could make up a significant amount of the total costs incurred, there is a direct relationship between our inputs and the transfer of control of goods or services to the customer in the event the customer invokes the termination for convenience clause, we would be entitled to costs incurred to date plus a reasonable profit. The majority of our revenues are recognized over time. Contract costs typically include labor, materials, overhead, and overhead.when applicable, subcontractor costs.
Contract estimates are based on various assumptions to project the outcome of future events that can span multiple months or years. These assumptions include labor productivity and availability; the complexity of the work to be performed; the cost and availability of materials; and the performance of subcontractors.
As a significant change in one or more of these estimates could affect the profitability of our contracts, we review and update our contract-related estimates on a regular basis. We recognize adjustments in estimated profit on contracts under the cumulative catch-up method. Under this method, the impact of the adjustment on profit recorded to date is recognized in the period the adjustment is identified. Revenue and profit in future periods of contract performance is recognized using the adjusted estimate. If at any time the estimate of contract profitability indicates an anticipated loss on the contract, we recognize the total loss in the quarter it is identified.
The impact of adjustments in contract estimates on our operating earnings can be reflected in either operating costs and expenses or revenue. See Note 2
Net cumulative catch up adjustments on profit recorded were not material during the three months ended March 30, 2019.
Payments under long-term contracts may be received before or after revenue is recognized. When revenue is recognized before we bill our customer, a contract asset is created for the net impact of these adjustmentswork performed but not yet billed. Similarly, when we receive payment before we ship our products to our unaudited condensed consolidated financial statementscustomer, a contract liability is created for the three-and nine months ended September 29, 2018.advance or progress payment.
Contract Assets and Contract Liabilities
Contract assets consist of our right to payment for work performed but not yet billed. Contract assets are transferred to accounts receivable when we ship the products to our customers and meet the shipping terms within the revenue contract. Contract

liabilities consist of advance or progress payments received from our customers prior to the time transfer of control occurs plus the estimated losses on contracts.

Recent Accounting Pronouncements
New Accounting Guidance Adopted in 20182019
In August 2017, the FASB issued ASU 2017-12, “Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging” (“ASU 2017-12”), which intends to improve and simplify accounting rules around hedge accounting. ASU 2017-12 refines and expands hedge accounting for both financial (i.e., interest rate) and commodity risks. In addition, it creates more transparency around how economic results are presented, both on the face of the financial statements and in the footnotes. The new guidance is effective for annual periods beginning after December 15, 2018, including interim periods within those annual periods, which is our interim period beginning January 1, 2019. Early adoption is permitted, including adoption in any interim period after the issuance of ASU 2017-12. The adoption of this standard did not have a material impact on our condensed consolidated financial statements.
In January 2017, the FASB issued ASU 2017-04, “Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment” (“ASU 2017-04”), which simplifies the subsequent measurement of goodwill, the amendments eliminate Step Two from the goodwill impairment test. The annual, or interim, goodwill impairment test is performed by comparing the fair value of a reporting unit with its carrying amount. An impairment charge should be recognized for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed

the total amount of goodwill allocated to that reporting unit. In addition, income tax effects from any tax deductible goodwill on the carrying amount of the reporting unit should be considered when measuring the goodwill impairment loss, if applicable. The amendments also eliminate the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment and, if it fails that qualitative test, to perform Step Two of the goodwill impairment test. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. The new guidance is effective for annual or interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The adoption of this standard did not have a material impact on our condensed consolidated financial statements.
In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)” (“ASU 2016-02”), which requires lessees to present right-of-use assets and lease liabilities on the balance sheet. Lessees are required to apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements or the additional transition method. Under the additional transition method, the cumulative effect of applying the new guidance is recognized as an adjustment to certain captions on the balance sheet, including the opening balance of retained earnings in the first quarter of 2019, and the prior years’ financial information will be presented under the prior accounting standard, ASC 840, “Leases,” (“ASC 840”). Additional guidance was issued subsequently as follows:
July 2018, the FASB issued ASU 2018-15, “Intangibles - Goodwill and Other - Internal-Use Software2018-11, “Leases (Topic 350-40)842): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract”Targeted Improvements” (“ASU 2018-15”2018-11”); and
July 2018, the FASB issued ASU 2018-10, “Codification Improvements to Topic 842, Leases” (“ASU 2018-10”)
All the new guidance is effective for us beginning January 1, 2019. The cumulative impact to our retained earnings at January 1, 2019 was a net decrease of $0.3 million. See Note 2.
Recently Issued Accounting Standards
In March 2019, the FASB issued ASU 2019-01, “Leases (Topic 842): Codification Improvements” (“ASU 2019-01”), which align theaddresses various lessor implementation issues and clarifies that lessees and lessors are exempt from certain interim disclosure requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contractassociated with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). Accordingly, the amendments require an entity (customer) in a hosting arrangement that is a service contract to follow the guidance in Subtopic 350-40 to determine which implementation costs to capitalize as an asset related to the service contract and which costs to expense. In addition, the amendments also require the entity (customer) to expense the capitalized implementation costsadoption of a hosting arrangement that is a service contract over the term of the hosting arrangement, which includes reasonably certain renewals.ASC 842. The new guidance is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years, which will be our interim period beginning January 1, 2020. Early adoption is permitted, including adoption in any interim period, and thus, we have chosen to early adopt ASU 2018-15 beginning July 1, 2018.permitted. We utilizedare evaluating the prospective transition method of adoption which allows us to capitalize software implementation projects currently in process. The adoption of ASU 2018-15 resulted in capitalizing $0.2 million of implementation costs and included as other current assets on our condensed consolidated balance sheets as of September 29, 2018.
In February 2018, the FASB issued ASU 2018-02, “Income Statement - Reporting Comprehensive Income (Topic 220):

Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (“AOCI”)” (“ASU 2018-02”), which provides financial statement preparers with an option to reclassify stranded income tax effects within AOCI to retained earnings in each period in which the effect of the change in U.S. federal corporate income tax rate in the Tax Cuts and Jobs Act (or portion thereof) is recorded. The new guidance was effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted and we have chosen to early adopt ASU 2018-02 beginning January 1, 2018. Further, in March 2018, the FASB issued ASU 2018-05, “Income Taxes (Topic 740): Amendments to SEC Paragraphs Pursuant to Staff Accounting Bulletin No. 118” (“ASU 2018-05”), which amends certain SEC material in Topic 740 for the income tax accounting implications of the recently issued Tax Cuts and Jobs Act (“Tax Cuts and Jobs Act”). The new guidance was effective upon inclusion in the FASB Codification. The adoption of these standards resulted in reclassifying $1.3 million of income tax effects from AOCI to retained earnings during the nine months ended September 29, 2018 on our condensed consolidated balance sheets. The income tax effects remaining in AOCI will be released into earnings as the related pre-tax AOCI amounts are reclassified to earnings.
In May 2017, the FASB issued ASU 2017-09, “Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting” (“ASU 2017-09”), which provides clarity on determining which changes to the terms and conditions of share-based payment awards require an entity to apply modification accounting under Topic 718. The new guidance was effective for us beginning January 1, 2018. The adoptionimpact of this standard did not have a significant impact on our condensed consolidated financial statements.
In March 2017, the FASB issued ASU 2017-07, “Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Costs” (“ASU 2017-07”), which requires an employer to report the service cost component in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of net benefit cost are required to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations, if one is presented. If a separate line item or items are used to present the other components of net benefit cost, that line item or items must be appropriately described. If a separate line item or items are not used, the line item or items used in the income statement to present the other components of net benefit cost must be disclosed. The amendments also allow only the service cost component to be eligible for capitalization when applicable. The new guidance was effective for us beginning January 1, 2018. The adoption of this standard did not have a material impact on our condensed consolidated financial statements. See Note 10.
In January 2017, the FASB issued ASU 2017-01, “Business Combinations (Topic 805): Clarifying the Definition of a Business” (“ASU 2017-01”), which clarifies the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of businesses. The new guidance was effective for us beginning January 1, 2018. The adoption of this standard did not have a significant impact on our condensed consolidated financial statements.
In August 2016, the FASB issued ASU 2016-15, “Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments” (“ASU 2016-15”), which addresses the following eight specific cash flow issues: Debt prepayment or debt extinguishment costs; settlement of zero-coupon debt instruments or other debt instruments with coupon interest rates that are insignificant in relation to the effective interest rate of the borrowing; contingent consideration payments made after a business combination; proceeds from the settlement of insurance claims; proceeds from the settlement of corporate-owned life insurance policies (“COLIs”) (including bank-owned life insurance policies [“BOLIs”]); distributions received from equity method investees; beneficial interests in securitization transactions; and separately identifiable cash flows and application of the predominance principle. The new guidance was effective for us beginning January 1, 2018. The adoption of this standard did not have a significant impact on our condensed consolidated financial statements.
In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers (Topic 606)” (“ASU 2014-09”), which outlines a new, single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. This new revenue recognition model provides a five-step analysis in determining when and how revenue is recognized. It depicts the transfer of promised goods or services to customers in an amount that reflects the consideration an entity expects to receive in exchange for those goods or services. Companies have the option of applying the provisions of ASU 2014-09 either retrospectively to each prior reporting period presented or retrospectively with the cumulative effect of initially applying this guidance recognized at the date of initial application. Additional guidance was issued subsequently as follows:
December 2016, the FASB issued ASU 2016-20, “Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers” (“ASU 2016-20”);
May 2016, the FASB issued ASU 2016-12, “Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients” (“ASU 2016-12”);

May 2016, the FASB issued ASU 2016-11, “Revenue Recognition (Topic 605) and Derivatives and Hedging (Topic 815): Rescission of SEC Guidance Because of Accounting Standards Updates 2014-09 and 2014-06 Pursuant to Staff Announcements at the March 3, 2016 EITF Meeting” (“ASU 2016-11”);
April 2016, the FASB issued ASU 2016-10, “Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing” (“ASU 2016-10”); and
August 2015, the FASB issued ASU 2015-14, “Revenue From Contracts With Customers (Topic 606)” (“ASU 2015-14”).
All of this new guidance was effective for us beginning January 1, 2018. The cumulative impact to our retained earnings at January 1, 2018 was a net increase of $8.7 million. See Note 2.
Recently Issued Accounting Standardsstandard.
In August 2018, the FASB issued ASU 2018-14, “Compensation - Retirement Benefits - Defined Benefit Plans - General (Topic 715-20): Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans” (“ASU 2018-14”), which will remove disclosures that no longer are considered cost-beneficial, clarify the specific requirements of disclosures, and add disclosure requirements identified as relevant. The new guidance is effective for fiscal years beginning after December 15, 2020, including interim periods within those fiscal years, which will be our interim period beginning January 1, 2021. Early adoption is permitted. We are evaluating the impact of this standard.
In August 2018, the FASB issued ASU 2018-13, “Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement” (“ASU 2018-13”), which should improve the effectiveness of fair value measurement disclosures by removing certain requirements, modifying certain requirements, and adding certain new requirements. The new guidance is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years, which will be our interim period beginning January 1, 2020. Early adoption is permitted. We are evaluating the impact of this standard.
In July 2018,June 2016, the FASB issued ASU 2018-11, “Leases2016-13, “Financial Instruments - Credit Losses (Topic 842)326): Targeted Improvements”Measurement of Credit Losses on Financial Instruments” (“ASU 2018-11”2016-13”), which provides entitiesis intended to improve financial reporting by requiring timelier recording of credit losses on loans and other financial instruments held by financial institutions and other organizations. ASU 2016-13 requires the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Financial institutions and other organizations will now use forward-looking information to better inform their credit loss estimates. Many of the loss estimation techniques applied today will still be permitted, although the inputs to those techniques will change to reflect the full amount of expected credit losses. Organizations will continue to use judgment to determine which loss estimation method is appropriate for their circumstances. ASU 2016-13 requires enhanced disclosures to help investors and other financial statement users better understand significant estimates and judgments used in estimating credit losses, as well as the credit quality and underwriting standards of an organization’s portfolio. These disclosures include qualitative and quantitative requirements that provide additional (and optional) transition method to adoptinformation about the new leases standard. Under this new transition method, an entity initially applies the new leases standard at adoption date and recognizes a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. Consequently, an entity's reporting for the comparative periods presentedamounts recorded in the financial statements in which the entity adopts the new lease requirements would continue to be in accordance with current GAAP (Topic 840). An entity electing this additional (and optional) transition method must provide the required Topic 840 disclosures for all periods that continue to be in accordance with Topic 840. The amendments do not change the existing disclosure requirements in Topic 840.statements. The new guidance is effective for fiscal years beginning after December 15, 2018,2019, including interim periods within those fiscal years, which will be our interim period beginning January 1, 2019.2020. We are evaluating the impact of this standard.
In July 2018, the FASB issued ASU 2018-10, “Codification Improvements to Topic 842), Leases” (“ASU 2018-10”), which provides clarification and guidance on multiple issues, some of which include how an entity should perform the lease classification reassessment, clarifying the periods covered by a lessor-only option to terminate the lease is included in the lease term, seller-lessee in a failed sale-and leaseback transaction should adjust the interest rate on its financial liability as necessary to ensure that the interest on the financial liability does not exceed the total payments (rather than the principal payments) on the financial liability. The new guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, which will be our interim period beginning January 1, 2019. We are evaluating the impact of this standard.
In January 2018, the FASB issued ASU 2018-01, “Leases (Topic 842): Land Easement Practical Expedient for Transition to Topic 842” (“ASU 2018-01”), which clarifies the application of the new leases guidance to land easements and eases adoption efforts for some land easements. The new guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, which will be our interim period beginning January 1, 2019. We are evaluating the impact of this standard.
In August 2017, the FASB issued ASU 2017-12, “Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging” (“ASU 2017-12”), which intends to improve and simplify accounting rules around hedge accounting. ASU 2017-12 refines and expands hedge accounting for both financial (i.e., interest rate) and commodity risks. In addition, it creates more transparency around how economic results are presented, both on the face of the financial statements and in the footnotes. The new guidance is effective for annual periods beginning after December 15, 2018, including interim periods within those annual periods, which will be our interim period beginning January 1, 2019. Early adoption is permitted, including adoption in any interim period after the issuance of ASU 2017-12. We are evaluating the impact of this standard.
In January 2017, the FASB issued ASU 2017-04, “Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment” (“ASU 2017-04”), which simplifies the subsequent measurement of goodwill, the amendments

eliminate Step Two from the goodwill impairment test. The annual, or interim, goodwill impairment test is performed by comparing the fair value of a reporting unit with its carrying amount. An impairment charge should be recognized for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. In addition, income tax effects from any tax deductible goodwill on the carrying amount of the reporting unit should be considered when measuring the goodwill impairment loss, if applicable. The amendments also eliminate the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment and, if it fails that qualitative test, to perform Step Two of the goodwill impairment test. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. The new guidance is effective for annual or interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. We are evaluating the impact of this standard.
In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)” (“ASU 2016-02”), which requires lessees to present right-of-use assets and lease liabilities on the balance sheet. Lessees are required to apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The new guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, which will be our interim period beginning January 1, 2019. We are currently completing the assessment and gap identification phase and have started the implementation of a new lease accounting software package. The assessment and gap identification phase includes gathering and analyzing our leases, and potential gaps in our internal controls as a result of adopting ASU 2016-02. The new accounting standard will be adopted using the additional transition method. Under this method, the cumulative effect of applying the new guidance is recognized as an adjustment to certain captions on the balance sheet, including the opening balance of retained earnings in the first quarter of 2019, and the prior years’ financial information will be presented under the prior accounting standard, ASC 840, “Leases,” (“ASC 840”). In addition, we will be utilizing the various practical expedients available under the new accounting standard. We have periodically briefed our Audit Committee of the Board of Directors on the progress made towards the adoption of this lease accounting standard. Since we have not completed the implementation of the software solution, we currently are unable to determine the exact impact to our condensed consolidated financial statements. We anticipate the majority of our leases will be recorded onto our condensed consolidated balance sheets. As such, various line items on our condensed consolidated balance sheets, income statements, and cash flows will be impacted.

Note 2. Adoption of Accounting Standards Codification 606842
We adopted ASC 606842 with an initial application as of January 1, 2018.2019. We utilized the modified retrospectiveadditional transition method, under which the cumulative effect of initially applying the new guidance is recognized as an adjustment to certain captions on the condensed consolidated balance sheet, including the opening balance of retained earnings in the ninethree months ended September 29, 2018.March 30, 2019. As part of the adoption of ASC 842, we have elected to utilize the following practical expedients that are permitted under ASC 842:
Need not reassess whether any expired or existing contracts are or contain leases;
Need not reassess the lease classification for any expired or existing leases;
Need not reassess initial direct costs for any existing leases;
As an accounting policy election by class of underlying asset, choose not to separate nonlease components from lease components and instead to account for each separate lease component and the nonlease components associated with that lease component as a single lease component; and
As an accounting policy election not to apply the recognition requirements in ASC 842 to short term leases (a lease at commencement date has a lease term of 12 months or less and does not contain a purchase option that the lessee is reasonably certain to exercise).
The net impact to the various captions on our January 1, 20182019 opening unaudited condensed consolidated balance sheets was as follows:

When a lease is identified, we recognize a right-of-use asset and a corresponding lease liability based on the present value of the lease payments over the lease term discounted using our incremental borrowing rate, unless an implicit rate is readily determinable. As the discount rate in our leases is usually not readily available and thus, we use our own incremental borrowing rate as the discount rate. Our incremental borrowing rate is based on the interest rate on our term loan, which is a secured rate.

The weighted average discount rate as of March 30, 2019 was as follows:

Note 3. Business Combination
OnIn April 23, 2018, we acquired 100.0% of the outstanding equity interests of Certified Thermoplastics Co., LLC (“CTP”), a privately-held leader in precision profile extrusions and extruded assemblies of engineered thermoplastic resins, compounds, and alloys for a wide range of commercial aerospace, defense, medical, and industrial applications. CTP is located in Santa Clarita, California. The acquisition of CTP was part of our strategy to diversify towards more customized, higher value, engineered products with greater aftermarket potential.
The purchase price for CTP was $30.7 million, net of cash acquired, all payable in cash. We paid an aggregate of $30.8 million in cash related to this transaction. We preliminarily allocated the gross purchase price of $30.8 million to the assets acquired and liabilities assumed at estimated fair values. The estimated fair value of the assets acquired included $8.1 million of intangible assets, $2.2 million of inventories, $1.5 million of accounts receivable, $0.6 million of property and equipment, $0.1 million of cash, less than $0.1 million of other current assets, and $0.4 million of liabilities assumed. The excess of the purchase price over the aggregate fair values of the net assets is recorded as goodwill. The allocation is subject to change as the estimates of fair value of current assets, non-current assets, identifiable intangible assets, and current liabilities are based on preliminary information and are subject to refinement. We are in the process of reviewing third party valuations of certain assets.

The following table summarizes the estimated fair value of the assets acquired and liabilities assumed at the date of acquisition (in thousands):

$18.6 million was recorded as goodwill. The intangible assets acquired were comprised of $8.0$6.9 million were preliminarily determined based on the estimated fair values using valuation techniques consistent with the income approach to measure fair value. The useful lives were estimated based on the underlying agreements or the future economic benefit expected to be received from the assets. The fair values of the identifiable intangible assets were estimated using several valuation methodologies, which represented Level 3 fair value measurements. The value for customer relationships was estimated based on a multi-period excess earnings approach, while the valueand $1.2 million for trade names and trademarks, was assessed using the relief from royalty methodology.
The goodwillall of $18.3 million arising from the acquisition is preliminarily attributable to the benefits we expect to derive from expected synergies from the transaction, including complementary products that will enhance our overall product portfolio, opportunities within new markets, andwhich were assigned an acquired assembled workforce.estimated useful life of 10 years. All the goodwill was assigned to the Structural Systems segment. Since the CTP acquisition, for tax purposes, was deemed an asset acquisition, the goodwill recognized is deductible for income tax purposes.
Acquisition related transaction costs are not included as components of consideration transferred but have been expensed as incurred. Total acquisition-related transaction costs incurred by us were zero and $0.6 million in the three months and nine months ended September 29, 2018, respectively, and charged to selling, general and administrative expenses.
CTP’s results of operations have been included in our condensed consolidated statements of income since the date of acquisition as part of the Structural Systems segment. Pro forma results of operations of the CTP acquisition during the three and nine months ended September 29, 2018 have not been presented as the effect of the CTP acquisition was not material to our financial results.
In September 2017, we acquired 100.0% of the outstanding equity interests of Lightning Diversion Systems, LLC (“LDS”), a privately-held worldwide leader in lightning protection systems serving the aerospace and defense industries, located in Huntington Beach, California. The acquisition of LDS was part of our strategy to enhance revenue growth by focusing on advanced proprietary technology on various aerospace and defense platforms.
The purchase price for LDS was $60.0 million, net of cash acquired, all payable in cash. We allocated the gross purchase price of $62.0 million to the assets acquired and liabilities assumed at estimated fair values. The excess of the purchase over the aggregate fair values was recorded as goodwill. All the goodwill was assigned to the Electronic Systems segment. Since the LDS acquisition, for tax purposes, was deemed an asset acquisition, the goodwill recognized is deductible for income tax purposes.
LDS’ results of operations have been included in our condensed consolidated statements of income since the date of acquisition as part of the Electronic Systems segment.


Note 4. Restructuring Activities
Summary of 2017 Restructuring Plan
In November 2017, management approved and commenced a restructuring plan that was intended to increase operating efficiencies.efficiencies (“2017 Restructuring Plan”). We currently estimate this initiative will result in $21.0completed the 2017 Restructuring Plan as of December 31, 2018 and have recorded cumulative expenses of $23.6 million, to $23.0with $14.8 million in total pre-tax restructuring charges throughrecorded during 2018, withand $8.8 million recorded during 2017. We recorded an additional $11.0 million during the nine months ended September 29, 2018, with $0.2 million recorded to cost of sales, and cumulative expenses of $19.8 million.

Note 5. Fair Value Measurements
Fair value is defined as the price that would be received for an asset or the price that would be paid to transfer a liability (an exit price) in the principal or most advantageous market in an orderly transaction between market participants on the measurement date. The accounting standard provides a framework for measuring fair value using a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. This hierarchy requires us to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Three levels of inputs that may be used to measure fair value are as follows:
Level 1 - Quoted prices (unadjusted) in active markets for identical assets or liabilities;

Level 2 - Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities; and
Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.
Our financial instruments consist primarily of cash and cash equivalents and interest rate cap derivatives designated as cash flow hedging instruments. The fair value of the interest rate cap hedge agreements was determined using pricing models that use observable market inputs as of the balance sheet date, a Level 2 measurement.
There were no transfers between Level 1, Level 2, or Level 3 financial instruments in the three months ended September 29, 2018.

Note 7.6. Goodwill
We perform our annual goodwill impairment test duringas of the first day of the fourth quarter. If certain factors occur, including significant under performance of our business relative to expected operating results, significant adverse economic and industry trends, significant decline in our market capitalization for an extended period of time relative to net book value, a decision to divest individual businesses within a reporting unit, or a decision to group individual businesses differently, we may perform an impairment test prior to the fourth quarter.
The increase in goodwill in Structural Systems was due to the acquisition of CTP on April 23, 2018. See Note 3.

OurIn November 2018, we completed new credit facility consistsfacilities to replace the Existing Credit Facilities. The new credit facilities consist of a $275.0$240.0 million senior secured term loan, which matures on June 26, 2020November 21, 2025 (“New Term Loan”), and a $200.0$100.0 million senior secured revolving credit facility (“New Revolving Credit Facility”), which matures on June 26, 2020November 21, 2023 (collectively, the “Credit“New Credit Facilities”).
The New Term Loan bears interest, at our option, at a rate equal to either (i) the Eurodollar Rate (defined as the London Interbank Offered Rate [“LIBOR”]) plus an applicable margin ranging from 3.75% to 4.00% per year or (ii) the Base Rate (defined as the highest of [a] Federal Funds Rate plus 0.50%, [b] Bank of America’s prime rate, and [c] the Eurodollar Rate plus 1.00%) plus an applicable margin ranging from 3.75% to 4.00% per year, in each case based upon the consolidated total net adjusted leverage ratio, typically payable quarterly. In addition, the New Term Loan requires installment payments of 0.25% of the outstanding principal balance of the New Term Loan amount on a quarterly basis. We made an aggregate total of $3.0 million of voluntary and mandatory principal prepayments under the New Term Loan during the three months ended March 30, 2019.
The New Revolving Credit Facilities bearFacility bears interest, at our option, at a rate equal to either (i) the Eurodollar Rate (defined as LIBOR) plus an applicable margin ranging from 1.50%1.75% to 2.75% per year or (ii) the Base Rate (defined as the highest of [a] Federal Funds Rate plus 0.50%, [b] Bank of America’s prime rate, and [c] the Eurodollar Rate plus 1.00%) plus an applicable margin ranging from 0.50%0.75% to 1.75% per year, in each case based upon the consolidated total net adjusted leverage ratio.ratio, typically payable quarterly. The undrawn portionsportion of the commitmentscommitment of the New Revolving Credit Facilities areFacility is subject to a commitment fee ranging from 0.175%0.20% to 0.300%0.30%, based upon the consolidated total net adjusted leverage ratio.
Further, if we aremeet the annual excess cash flow threshold, we will be required to make excess cash flow payments. The annual mandatory prepayments of amounts outstanding under the Term Loan. The mandatory prepaymentsexcess cash flow payments will be made quarterly,based on (i) 50% of the excess cash flow amount if the adjusted leverage ratio is greater than 3.25 to 1.0, (ii) 25% of the excess cash flow amount if the adjusted leverage ratio is less than or equal to 5.0% per year3.25 to 1.0

but greater than 2.50 to 1.0, and (iii) zero percent of the original aggregate principalexcess cash flow amount duringif the first two years and increaseadjusted leverage ratio is less than or equal to 7.5% per year during the third year, and increase2.50 to 10.0% per year during the fourth year and fifth years, with the remaining balance payable on June 26, 2020. The loans under the Revolving Credit Facility are due on June 26, 2020.1.0. As of September 29, 2018,March 30, 2019, we were in compliance with all covenants required under the New Credit Facilities.
We have been making periodic voluntary principal prepayments on our Existing Credit Facilities and in conjunction with the closing of the New Credit Facilities on November 21, 2018, we drew down $240.0 million on the New Term Loan, $7.9 million on the New Revolving Credit Facility and used those proceeds along with current cash on hand to pay off the Existing Credit Facilities of $247.9 million. The New Term Loan replacing the term loan that was a part of the Existing Credit Facilities (“Existing Term Loan”) was considered an extinguishment of debt except for the portion related to a creditor that was part of the Existing Term Loan and the New Term Loan and in which case, it was considered a modification of debt. As a result, we expensed the portion of the unamortized debt issuance costs related to the Existing Term Loan that was considered an extinguishment of debt of $0.4 million. In addition, the New Revolving Credit Facility replacing the existing revolving credit facility that was part of the Existing Credit Facilities (“Existing Revolving Credit Facility”) was considered an extinguishment of debt except for the portion related to the creditors that were part of the Existing Revolving Credit Facility and the New Revolving Credit Facility and in which case, it was considered a modification of debt. As a result, we expensed the portion of the unamortized debt issuance costs related to the Existing Revolving Credit Facility that was considered an extinguishment of debt of $0.5 million. As such, an aggregate total loss on extinguishment of debt of $0.9 million was recorded in 2018.
Further, we incurred $4.8$3.5 million of new debt issuance costs that can be capitalized related to the New Credit Facilities, of which $1.7 million were allocated to the New Term Loan and the $1.8 million was allocated to the New Revolving Credit facility. The New Term Loan new debt issuance costs of $1.7 million and remaining unamortized Existing Term Loan debt issuance costs of $0.1 million, for an aggregate total of $1.8 million of debt issuance costs related to the New Term Loan were capitalized and are being amortized over the seven years life of the New Term Loan. The New Revolving Credit FacilitiesFacility new debt issuance costs of $1.8 million and thoseremaining unamortized Existing Revolving Credit Facility debt issuance costs of $0.2 million, for an aggregate total of $2.0 million of debt issuance costs related to the New Revolving Credit Facility were capitalized and are being amortized over the five yearyears life of the New Revolving Credit Facilities.Facility.
In July 2017, we entered into a technical amendment to the Credit Facilities (“First Amendment”) which provides more flexibility to close certain qualified acquisitions permitted under the Credit Facilities.

We have made all mandatory prepayments under the Term Loan and thus, no mandatory payments are due until the Term Loan matures in June 2020. We did not make any voluntary principal prepayments under the Term Loan during the three and nine months ended September 29, 2018.
On April 23, 2018, we acquired CTP for a purchase price of $30.7 million, net of cash acquired, all payable in cash. We paid an aggregate of $30.8 million in cash related to this transaction by drawing down on the Revolving Credit Facility. See Note 3.
In September 2017, we acquired LDS for a purchase price of $60.0 million, net of cash acquired, all payable in cash. Upon the closing of the transaction, we paid $61.4 million in cash by drawing down on the Revolving Credit Facility. The remaining $0.6 million was paid in October 2017 in cash, also by drawing down on theExisting Revolving Credit Facility. See Note 3.
As of September 29, 2018,March 30, 2019, we had $129.0$96.6 million of unused borrowing capacity under the Revolving Credit Facility, after deducting $70.7$3.2 million for draw down on the New Revolving Credit Facility and $0.3$0.2 million for standby letters of credit.
The New Credit Facilities were entered into by us (“Parent Company”) and guaranteed by all of our subsidiaries, other than one subsidiarytwo subsidiaries that were considered minor (“Subsidiary Guarantors”) that was considered minor.. The Subsidiary Guarantors jointly and severally guarantee the New Credit Facilities. The Parent Company has no independent assets or operations and the Subsidiary Guarantors jointly and severally guarantee, on a senior unsecured basis, the Credit Facilities. Therefore,therefore, no condensed consolidating financial information for the Parent Company and its subsidiaries are presented.
In October 2015, we entered into interest rate cap hedges designated as cash flow hedges with a portion of these interest rate cap hedges maturing on a quarterly basis, and a final quarterly maturity datesdate of June 2020, and in aggregate, totaling $135.0 million of our debt. We paid a total of $1.0 million in connection with entering into the interest rate cap hedges. See Note 51 for further discussion.information.
In December 2018, 2017, and 2016, we entered into agreements to purchase $2.2 million, $14.2 million, and $9.9 million of industrial revenue bonds (“IRBs”) issued by the city of Parsons, Kansas (“Parsons”) and concurrently, sold $2.2 million, $14.2 million, and $9.9 million of property and equipment (“Property”) to Parsons as well as entered into lease agreements to lease the Property from Parsons (“Leases”) with lease payments totaling $2.2 million, $14.2 million, and $9.9 million over the lease terms, respectively. The sale of the Property and concurrent lease back of the Property in December 2018, 2017, and 2016 did not meet the sale-leaseback accounting requirements as a result of control not deemed to have transferred to the buyer-lessor under ASC 842 and our continuous involvement with the Property under ASC 840 and thus, the $2.2 million, $14.2 million, and $9.9 million in cash received from Parsons was not recorded as a sale but as a financing obligation.obligation, respectively. Further, the Leases included a right of offset so long as we continue to own the IRBs and thus, the financing obligationobligations of $2.2 million, $14.2 million, and $9.9 million waswere offset against the $2.2 million, $14.2 million, and $9.9 million, respectively, of IRBs assets and are presented net on the condensed consolidated balance sheets with no impact to the condensed consolidated statements of income statements or condensed consolidated cash flow statements.

Note 11.10. Indemnifications
We have made guarantees and indemnities under which we may be required to make payments to a guaranteed or indemnified party, in relation to certain transactions, including revenue transactions in the ordinary course of business. In connection with certain facility leases, we have indemnified our lessors for certain claims arising from our use of the facility under our lease. We indemnify our directors and officers to the maximum extent permitted under the laws of the State of Delaware.
However, we have a directors and officers insurance policy that may reduce our exposure in certain circumstances and may enable us to recover a portion of future amounts that may be payable, if any. The duration of the guarantees and indemnities vary and, in many cases, are subject to statutes of limitations. The majority of guarantees and indemnities do not provide any limitations of the maximum potential future payments we could be obligated to make. Historically, payments related to these guarantees and indemnities have been immaterial. We estimate the amount of our indemnification obligations as insignificant based on this history and insurance coverage and therefore, have not recorded any liability for these guarantees and indemnities on the accompanying condensed consolidated balance sheets. Further, when considered with our insurance coverage, although recorded through different captions on our condensed consolidated balance sheets, the potential impact is further mitigated.
 
Note 12.11. Income Taxes
The provision for income taxes is determined using an estimated annual effective tax rate, which is generally less than the U.S. federal statutory rate, primarily due to research and development (“R&D”) tax credits. Our effective tax rate may be subject to fluctuations during the year as new information is obtained, which may affect the assumptions used to estimate the annual effective tax rate, including factors such as expected utilization of R&D tax credits, valuation allowances against deferred tax assets, the recognition or derecognition of tax benefits related to uncertain tax positions, and changes in or the interpretation of tax laws in jurisdictions where we conduct business. Also, excess tax benefits and tax deficiencies related to our equity compensation recognized in the income statement could result in fluctuations in our effective tax rate period-over-period depending on the volatility of our stock price and how many awards vest in the period. We recognize deferred tax assets and liabilities for temporary differences between the financial reporting basis and the tax basis of our assets and liabilities along with net operating loss and tax credit carryovers.

We record a valuation allowance against our deferred tax assets to reduce the net carrying value to an amount that we believe is more likely than not to be realized. When we establish or reduce our valuation allowances against our deferred tax assets, the provision for income taxes will increase or decrease, respectively, in the period when that determination is made.
On December 22, 2017, the President of the United States signed into law the Tax Cuts and Jobs Act (“2017 Tax Act”) which, among a broad range of tax reform measures, reduced the U.S. corporate tax rate from 35.0% to 21.0% effective January 1, 2018. The reduction in the U.S. corporate tax rate required the federal portion of our deferred tax assets and liabilities at December 31, 2017 to be re-measured at the enacted tax rate expected to apply when the temporary differences are to be realized or settled using 21.0%.
SEC Staff Accounting Bulletin No. 118, “Income Tax Accounting Implications of the Tax Cuts and Jobs Act” (“SAB 118”), allows us to record provisional amounts for the tax effects of the 2017 Tax Act when we do not have necessary information available, prepared, or analyzed in reasonable detail to finalize its accounting for the changes in the tax law during a measurement period not to extend beyond one year of the enactment date. During the nine months ended September 29, 2018, we did not recognize any changes to the provisional amounts recorded in our 2017 Annual Report on Form 10-K in connection with the 2017 Tax Act. We expect to finalize our analysis within the measurement period in accordance with SAB 118 after completing our reviews of additional guidance issued by the Internal Revenue Service (“IRS”) and available tax methods and elections related to 2017 tax return positions.
We recorded income tax expense of $0.1$1.0 million for the three months ended September 29, 2018March 30, 2019 compared to $0.9an income tax benefit of $0.2 million for the three months ended September 30, 2017.March 31, 2018. The decrease in income tax expense for the third quarter of 2018 compared to the third quarter of 2017 was primarily due to the reduction in the U.S. corporate tax rate from 35.0% to 21.0% and lower pre-tax income in the third quarter of 2018 compared to the third quarter of 2017. The decrease was partially offset by the repeal of the U.S. Domestic Production Activities Deduction in 2018.
We recorded income tax expense of $0.1 million for the nine months ended September 29, 2018 compared to $2.1 million for the nine months ended September 30, 2017. The decreaseincrease in income tax expense for the first nine monthsquarter of 20182019 compared to the first nine monthsquarter of 20172018 was primarily due to the reduction in the U.S. corporate tax rate from 35.0% to 21.0% and lower

higher pre-tax income infor the first nine monthsquarter of 20182019 compared to the first nine monthsquarter of 2017. The decrease was partially offset by the repeal of the U.S. Domestic Production Activities Deduction in 2018 and a reduction in tax benefits from deductions of share-based compensation expense in excess of the compensation expense recorded for financial reporting purposes.2018.
Our total amount of unrecognized tax benefits was $5.2$5.4 million and $5.3 million as of September 29, 2018March 30, 2019 and December 31, 2017,2018, respectively. If recognized, $3.4 million would affect the effective tax rate. We do not reasonably expect significant increases or decreases to our unrecognized tax benefits in the next twelve months.

Note 13.12. Contingencies
Structural Systems has been directed by California environmental agencies to investigate and take corrective action for groundwater contamination at its facilities located in El Mirage and Monrovia, California. Based on currently available information, Ducommun has established an accrual for its estimated liability for such investigation and corrective action of $1.5 million at both September 29, 2018March 30, 2019 and December 31, 2017,2018, which is reflected in other long-term liabilities on its condensed consolidated balance sheets.
Structural Systems also faces liability as a potentially responsible party for hazardous waste disposed at landfills located in Casmalia and West Covina, California. Structural Systems and other companies and government entities have entered into consent decrees with respect to these landfills with the United States Environmental Protection Agency and/or California environmental agencies under which certain investigation, remediation and maintenance activities are being performed. Based on currently available information, Ducommun preliminarily estimates that the range of its future liabilities in connection with the landfill located in West Covina, California is between $0.4 million and $3.1 million. Ducommun has established an accrual for its estimated liability in connection with the West Covina landfill of $0.4 million at September 29, 2018,March 30, 2019, which is reflected in other long-term liabilities on its condensed consolidated balance sheet. Ducommun’s ultimate liability in connection with these matters will depend upon a number of factors, including changes in existing laws and regulations, the design and cost of construction, operation and maintenance activities, and the allocation of liability among potentially responsible parties.
In the normal course of business, Ducommun and its subsidiaries are defendants in certain other litigation, claims and inquiries, including matters relating to environmental laws. In addition, Ducommun makes various commitments and incurs contingent liabilities.liabilities in the ordinary course of business. While it is not feasible to predict the outcome of these matters, Ducommun does not presently expect that any sum it may be required to pay in connection with these matters would have a material adverse effect on its condensed consolidated financial position, results of operations or cash flows.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations
Overview
Ducommun Incorporated (“Ducommun,” “the Company,” “we,” “us” or “our”) is a leading global provider of engineering and manufacturing services for high-performance products and high-cost-of failure applications used primarily in the aerospace and defense (“A&D”), industrial, medical and other industries (collectively, “Industrial”). We differentiate ourselves as a full-service solution-based provider, offering a wide range of value-added products and services in our primary businesses of electronics, structures and integrated solutions. We operate through two primary business segments: Electronic Systems and Structural Systems, each of which is a reportable segment.
We adopted ASC 606, “Revenue from Contracts with Customers”842, “Leases” (“ASC 606”842”), as of January 1, 2018,2019, using the modified retrospectiveadditional transition method of adoption. As such, our results for the three and nine months ended September 29, 2018March 30, 2019 are reported under ASC 606842 while our results for the three and nine months ended September 30, 2017March 31, 2018 are reported under the prior revenue recognitionlease accounting standard, ASC 605, “Revenue Recognition”840, “Leases” (“ASC 605”840”). However, our discussions are primarily based on a comparison of our results in the three and nine months ended September 29, 2018 under ASC 605 compared to the three and nine months ended September 30, 2017 also under ASC 605. See Note 1 and Note 2 to condensed consolidated financial statements included in Part I, Item I of this Form 10-Q.
ThirdFirst quarter 20182019 highlights:
Revenues of $159.8$172.6 million
Net income of $4.2$7.5 million, or $0.36$0.64 per diluted share
Adjusted EBITDA of $18.1 million
Backlog of $780.1$21.7 million
Non-GAAP Financial Measures
Adjusted earnings before interest, taxes, depreciation, amortization, stock-based compensation expense, and restructuring charges and inventory purchase accounting adjustments (“Adjusted EBITDA”) was $18.1$21.7 million and $14.6$14.5 million for the three months ended September 29,March 30, 2019 and March 31, 2018, and September 30, 2017, respectively.
When viewed with our financial results prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and accompanying reconciliations, we believe Adjusted EBITDA provides additional useful information to clarify and enhance the understanding of the factors and trends affecting our past performance and future prospects. We define these measures, explain how they are calculated and provide reconciliations of these measures to the most comparable GAAP measure in the table below. Adjusted EBITDA and the related financial ratios, as presented in this Quarterly Report on Form 10-Q (“Form 10-Q”), are supplemental measures of our performance that are not required by, or presented in accordance with, GAAP. They are not a measurement of our financial performance under GAAP and should not be considered as alternatives to net income or any other performance measures derived in accordance with GAAP, or as an alternative to net cash provided by operating activities as measures of our liquidity. The presentation of these measures should not be interpreted to mean that our future results will be unaffected by unusual or nonrecurring items.
We use Adjusted EBITDA non-GAAP operating performance measures internally as complementary financial measures to evaluate the performance and trends of our businesses. We present Adjusted EBITDA and the related financial ratios, as applicable, because we believe that measures such as these provide useful information with respect to our ability to meet our operating commitments.
Adjusted EBITDA has limitations as an analytical tool, and you should not consider it in isolation or as substitutesa substitute for analysis of our results as reported under GAAP. Some of these limitations include:
They do not reflect our cash expenditures, future requirements for capital expenditures or contractual commitments;
They do not reflect changes in, or cash requirements for, our working capital needs;
They do not reflect the significant interest expense or the cash requirements necessary to service interest or principal payments on our debt;
Although depreciation and amortization are non-cash charges, the assets being depreciated and amortized will often have to be replaced in the future, and Adjusted EBITDA does not reflect any cash requirements for such replacements;

They are not adjusted for all non-cash income or expense items that are reflected in our statements of cash flows;
They do not reflect the impact on earnings of charges resulting from matters unrelated to our ongoing operations; and

Other companies in our industry may calculate Adjusted EBITDA differently from us, limiting their usefulness as comparative measures.
Because of these limitations, Adjusted EBITDA and the related financial ratios should not be considered as measures of discretionary cash available to us to invest in the growth of our business or as a measure of cash that will be available to us to meet our obligations. You should compensate for these limitations by relying primarily on our GAAP results and using Adjusted EBITDA only as supplemental information. See our Condensed Consolidated Financial Statements contained in this Form 10-Q.
However, in spite of the above limitations, we believe that Adjusted EBITDA is useful to an investor in evaluating our results of operations because these measures:
Are widely used by investors to measure a company’s operating performance without regard to items excluded from the calculation of such terms, which can vary substantially from company to company depending upon accounting methods and book value of assets, capital structure and the method by which assets were acquired, among other factors;
Help investors to evaluate and compare the results of our operations from period to period by removing the effect of our capital structure from our operating performance; and
Are used by our management team for various other purposes in presentations to our Board of Directors as a basis for strategic planning and forecasting.
The following financial items have been added back to or subtracted from our net income when calculating Adjusted EBITDA:
Interest expense may be useful to investors for determining current cash flow;
Income tax expense may be useful to investors because it represents the taxes which may be payable for the period and the change in deferred taxes during the period, and may reduce cash flow available for use in our business;
Depreciation may be useful to investors because it generally represents the wear and tear on our property and equipment used in our operations;
Amortization expense may be useful to investors because it represents the estimated attrition of our acquired customer base and the diminishing value of product rights;
Stock-based compensation may be useful to our investors for determining current cash flow; and
Restructuring charges may be useful to our investors in evaluating our core operating performance;
Purchase accounting inventory step-ups may be useful to our investors as they do not necessarily reflect the current or on-going cash charges related to our core operating performance.

Reconciliations of net income to Adjusted EBITDA and the presentation of Adjusted EBITDA as a percentage of net revenues were as follows:

Gross Profit
Gross profit consists of net revenues less cost of sales. Cost of sales includes the cost of production of finished products and other expenses related to inventory management, manufacturing quality, and order fulfillment. Gross profit margin as a percentage of net revenues increased year-over-year in the three months ended September 29, 2018March 30, 2019 to 19.5%20.7%, compared to the three months ended September 30, 2017March 31, 2018 of 18.8%17.8% due to favorable product mix, manufacturing efficiencies, and favorablehigher manufacturing volume, partially offset by higher compensation and benefits costs and higher other manufacturing costs.
Gross profit margin as a percentage of net revenues increased year-over-year in the nine months ended September 29, 2018 to 19.3%, compared to the nine months ended September 30, 2017 of 18.6% due to favorable product mix and favorable manufacturing volume, partially offset by higher compensation and benefit costs, higher other manufacturing costs, and lack of forward loss reserve release in the current year.
Selling, General and Administrative (“SG&A”) Expenses
SG&A expenses increased $2.3$3.5 million year-over-year in the three months ended September 29, 2018March 30, 2019 compared to the three months ended September 30, 2017March 31, 2018 due to higher compensation and benefit costs of $1.2 million and higher professional services fees of $0.6 million.
SG&A expenses increased $2.4 million year-over-year in the nine months ended September 29, 2018 compared to the nine months ended September 30, 2017 due to higher professional services fees of $2.3 million, which includes acquisition related costs of $0.6 million, and amortization of intangibles of $1.2 million, partially offset by lower compensation and benefit costs of $1.1 million.

Interest expense increased year-over-year in the three months ended September 29, 2018March 30, 2019 compared to the three months ended September 30, 2017March 31, 2018 due to a higher outstanding balance on the Revolving Credit Facility, reflecting the acquisitionsacquisition of Certified Thermoplastics Co., LLC (“CTP”) in April 2018 and Lightning Diversion Systems, LLC (“LDS”) during September 2017, and higher interest rates.
Interest expense increased year-over-year in the nine months ended September 29, 2018 compared to the nine months ended September 30, 2017 due to a higher outstanding balance on the Revolving Credit Facility, reflecting the acquisitions of CTP and LDS, and higher interest rates.
Income Tax Expense
We recorded income tax expense of $0.1$1.0 million for the three months ended September 29, 2018March 30, 2019 compared to $0.9an income tax benefit of $0.2 million for the three months ended September 30, 2017.March 31, 2018. The decrease in income tax expense for the third quarter of 2018 compared to the third quarter of 2017 was primarily due to the reduction in the U.S. corporate tax rate from 35.0% to 21.0% and lower pre-tax income in the third quarter of 2018 compared to the third quarter of 2017. The decrease was partially offset by the repeal of the U.S. Domestic Production Activities Deduction in 2018.
We recorded income tax expense of $0.1 million for the nine months ended September 29, 2018 compared to $2.1 million for the nine months ended September 30, 2017. The decreaseincrease in income tax expense for the first nine monthsquarter of 20182019 compared to the first nine monthsquarter of 20172018 was primarily due to the reduction in the U.S. corporate tax rate from 35.0% to 21.0% and lowerhigher pre-tax income infor the first nine monthsquarter of 20182019 compared to the first nine monthsquarter of 2017. The decrease was partially offset by the repeal of the U.S. Domestic Production Activities Deduction in 2018 and a reduction in tax benefits from deductions of share-based compensation expense in excess of the compensation expense recorded for financial reporting purposes.2018.
Our total amount of unrecognized tax benefits was $5.2$5.4 million and $5.3 million as of September 29, 2018March 30, 2019 and December 31, 2017,2018, respectively. If recognized, $3.4 million would affect the effective tax rate. We do not reasonably expect significant increases or decreases to our unrecognized tax benefits in the next twelve months.
Net Income and Earnings per Share
Net income and earnings per share for the three months ended September 29, 2018March 30, 2019 were $4.2$7.5 million, or $0.36$0.64 per diluted share, compared to $4.7$2.6 million, or $0.41$0.22 per diluted share, for the three months ended September 30, 2017.March 31, 2018. The decreaseincrease in net income for the three months ended September 29, 2018March 30, 2019 compared to the three months ended September 30, 2017March 31, 2018 was due to $3.4$8.9 million of restructuring charges. The $5.0 million increase inhigher gross profit was due toas a result of higher revenues and improved operating performanceperformance. Restructuring charges were lower by $2.2 million that was partially offset by $2.3$3.5 million of higher selling, general and administrative expenses, and $0.3 million of higher interest expense.
Net income and earnings per share for the nine months ended September 29, 2018 were $8.4 million, or $0.72 per diluted share, compared to $10.6 million, or $0.92 per diluted share, for the nine months ended September 30, 2017. The decrease in net income for the nine months ended September 29, 2018 compared to the nine months ended September 30, 2017 was due to $11.0 million of restructuring charges, $0.2 million of which was included in cost of sales. The $12.5 million increase in gross profit was due to higher revenues and improved operating performance that was partially offset by $3.1$1.5 million of higher interest expense, and $2.4 millionhigher income taxes of higher selling, general and administrative expenses.$1.3 million.

Business Segment Performance
We report our financial performance based upon the two reportable operating segments: Electronic Systems and Structural Systems. The results of operations differ between our reportable operating segments due to differences in competitors, customers, extent of proprietary deliverables and performance. The following table summarizes our business segment performance for the three and nine months ended September 29, 2018March 30, 2019 and September 30, 2017:

Backlog
We define backlog as potential revenue that is based on customer placed purchase orders (“POs”) and long-term agreements (“LTAs”) with firm fixed price and firmexpected delivery dates of 24 months or less. The majority of the LTAs do not meet the definition of a contract under ASC 606 and thus, the backlog amount disclosed below is greater than the backlogremaining performance obligations amount disclosed in Note 1 to our condensed consolidated financial statements included in Part I, Item 1 of this Form 10-Q. Backlog is subject to delivery delays or program cancellations, which are beyond our control. Backlog is affected by timing differences in the placement of customer orders and tends to

be concentrated in several programs to a greater extent than our net revenues. Backlog in industrial markets tends to be of a shorter duration and is generally fulfilled within a three month period. As a result of these factors, trends in our overall level of backlog may not be indicative of trends in our future net revenues.
The increase in backlog was primarily in the commercial aerospace end-use markets and defense technologies end-use markets. $552.0$625.0 million of total backlog is expected to be delivered over the next 12 months. The following table summarizes our backlog as of September 29, 2018March 30, 2019 and December 31, 2017:2018:

OurIn November 2018, we completed new credit facility consistsfacilities to replace the Existing Credit Facilities. The new credit facilities consist of a $275.0$240.0 million senior secured term loan, which matures on June 26, 2020November 21, 2025 (“New Term Loan”), and a $200.0$100.0 million senior secured revolving credit facility (“New Revolving Credit Facility”), which matures on June 26, 2020November 21, 2023 (collectively, the “Credit“New Credit Facilities”). We are required to make mandatory prepaymentsinstallment payments of amounts0.25% of the outstanding underprincipal balance of the New Term Loan.Loan amount on a quarterly basis. In addition, if we meet the annual excess cash flow threshold, we will be required to make excess flow payments on an annual basis. Further, the undrawn portion of the commitment of the New Revolving Credit Facility is subject to a commitment fee ranging from 0.20% to 0.30%, based upon the consolidated total net adjusted leverage ratio. As of September 29, 2018,March 30, 2019, we were in compliance with all covenants required under the Credit Facilities. See Note 98 to our condensed consolidated financial statements included in Part I, Item 1 of this Form 10-Q for further information. In July 2017, we entered into a technical amendment to the Credit Facilities (“First Amendment”) which provides more flexibility to close certain qualified acquisitions permitted under the Credit Facilities. We have made allan aggregate total of $3.0 million of voluntary and mandatory principal prepayments under the Term Loan and thus, no mandatory payments are due untilduring the Term Loan matures in June 2020.three months ended March 30, 2019.
In October 2015, we entered into interest rate cap hedges designated as cash flow hedges with maturity dates of June 2020, and in aggregate, totaling $135.0 million of our debt. We paid a total of $1.0 million in connection with entering into the interest rate cap hedges.

OnIn April 23, 2018, we acquired Certified Thermoplastics Co., LLC (“CTP”) for a purchase price of $30.7 million, net of cash acquired, all payable in cash. We paid an aggregate of $30.8 million in cash by drawing down on the Revolving Credit Facility. See Note 3 to our condensed consolidated financial statements included in Part I, Item 1 of this Form 10-Q.
In September 2017, we acquired LDS for a purchase price of $60.0 million, net of cash acquired, all payable in cash. Upon the closing of the transaction, we paid $61.4 million in cash by drawing down on the Revolving Credit Facility. The remaining $0.6 million was paid in October 2017 in cash, also by drawing down on the Revolving Credit Facility. See Note 3 to our condensed consolidated financial statements included in Part I, Item 1 of this Form 10-Q.
We expect to spend a total of $15.0 million to $17.0 million for capital expenditures in 20182019 financed by cash generated from operations, principally to support new contract awards in StructuralElectronic Systems and ElectronicStructural Systems. As part of our strategic plan to become a Tier 2 supplier of higher-level assemblies and win new contract awards, additional up-front investment in tooling will be required for newer programs which have higher engineering content and higher levels of complexity in assemblies.
We believe the ongoing aerospace and defense subcontractor consolidation makes acquisitions an increasingly important component of our future growth. We will continue to make prudent acquisitions and capital expenditures for manufacturing equipment and facilities to support long-term contracts for commercial and military aircraft and defense programs.
We continue to depend on operating cash flow and the availability of our New Credit Facilities to provide short-term liquidity. Cash generated from operations and bank borrowing capacity are expected to provide sufficient liquidity to meet our obligations during the next twelve months.
In November 2017, management approved and commenced a restructuring plan that was intended to increase operating efficiencies. We have finalized our decisions and are executing to the restructuring plan. This will result in additional restructuring charges during the remainder of 2018. On an annualized basis, beginning in 2019, we anticipate these restructuring actions will result in estimated total savings of $14.0 million.

Cash Flow Summary
Net cash provided byused in operating activities for the ninethree months ended September 29, 2018 increased to $33.4March 30, 2019 was $1.7 million, compared to $27.4cash provided by of $10.3 million for the ninethree months ended September 30, 2017.March 31, 2018. The higherlower net cash generated during the first ninethree months of 20182019 was due to improved working capital management,the decrease in accrued and other liabilities, partially offset by lowerhigher net income.
Net cash used in investing activities was $43.4$3.2 million for the ninethree months ended September 29, 2018March 30, 2019 compared to $83.5$3.3 million in the ninethree months ended September 30, 2017.March 31, 2018. The lower net cash used in the first ninethree months of 20182019 compared to the prior year period was due to lower payments for business combination and lower purchases of property and equipment.
Net cash provided byused in financing activities for the ninethree months ended September 29, 2018March 30, 2019 of $11.4$1.6 million was lower than the prior year

period due to lower net borrowingsrepayments on the Revolving Credit Facility.

Off-Balance Sheet Arrangements
Our off-balance sheet arrangements consist of operating and finance leases not recorded as a result of the practical expedients utilized as a part of the adoption of ASC 842 as of January 1, 2019 and indemnities.
Critical Accounting Policies
The preparation of our condensed consolidated financial statements in accordance with accounting principles generally accepted in the United States requires estimation and judgment that affect the reported amounts of net revenues, expenses, assets and liabilities. For a description of our critical accounting policies, please refer to “Critical Accounting Policies” in Part II, Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” of our 20172018 Annual Report on Form 10-K. As a result of adopting ASC 606842 as of January 1, 2018,2019, there have been material changes into our criticallease accounting policies during the ninethree months ended September 29, 2018,March 30, 2019, and are described in Note 1 and Note 2 to our condensed consolidated financial statements included in Part I, Item I of this Form 10-Q.

Item 3. Quantitative and Qualitative Disclosures About Market Risk
Our main market risk exposure relates to changes in U.S. interest rates on our outstanding long-term debt. At September 29, 2018,March 30, 2019, we had total borrowings of $230.7$233.2 million under our New Credit Facilities which bearFacilities.
