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 subsidiariesoperations are organized into two strategic2 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 aerospace, defense, industrialA&D and medical and otherIndustrial end-use markets. Electronic Systems’ product offerings primarily range from prototype development to complex assemblies. Structural Systems designs, engineers and manufactures large, complex contoured aerospace structuralaerostructure 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. BothAll 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, 20162019 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, 2016. We followed the same accounting policies for interim reporting.2019. 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, 2016.2019.
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 30, 2017March 28, 2020 are not necessarily indicative of the results to be expected for the full year ending December 31, 2017.2020.
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.
Use of Estimates
Certain amounts and disclosures included in the unaudited condensed consolidated financial statements requiresrequire 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.estimates.Certain reclassifications have been made to prior period amounts to conform to the current year’s presentation.

Impact of the COVID-19 Pandemic
The commercial aerospace industry continues to be adversely affected by the impact from the continued grounding of the Boeing 737 MAX program combined with the outbreak of the COVID-19 pandemic which resulted in the announcements towards the end of our first quarter by two of our largest customers, The Boeing Company (“Boeing”) and Spirit Aerosystems Holdings, Inc. (“Spirit”), to temporarily shut down production at some of their facilities. While Boeing has resumed production at two of their manufacturing facilities subsequent to our quarter ended March 28, 2020, we expect there will be an impact to our condensed consolidated financial results for the second quarter of 2020. Given the uncertainties surrounding the duration and impact of these matters, we cannot reasonably estimate with certainty the related financial impact to our full year 2020 financial results; however, there could be a material adverse impact on our business, results of operations and financial condition for some portion, if not the remainder, of 2020.

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.
Divestitures

We also have interest rate cap hedge agreements for which the sale on the same date, to sell our operation located in Pittsburgh, Pennsylvania for a preliminary sales price of $38.5 million in cash.

$18.3 million. In the fourth quarter of 2016, we finalized the sale with a final sales price of $38.6 million in cash. The final net assets sold were $24.0 million, net liabilities sold were $4.0 million, and direct transaction costs incurred were $0.3 million, resulting in a gain on divestiture of $18.3 million.
In February 2016, we entered into an agreement to sell our Huntsville, Alabama and Iuka, Mississippi (collectively, “Miltec”) operations for a preliminary sales price of $14.6 million, in cash, subject to post-closing adjustments. We divested this facility as part of our overall strategy to streamline operations, which included consolidating our footprint. However, the sale of the Miltec operation did not represent a strategic shift in our business and thus, was included in the ongoing operating results in the condensed consolidated income statements for all periods presented. We completed the sale on March 25, 2016. Preliminary net assets sold were $15.4 million, net liabilities sold were $2.6 million, and direct transaction costs incurred during the current period were $1.3 million, resulting in a preliminary gain on divestiture of $0.5 million. In the fourth quarter of 2016, we finalized the sale with a final sales price of $13.3 million in cash. The final net assets sold were $15.4 million, net liabilities sold were $2.7 million, and direct transaction costs incurred were $1.3 million, resulting in a loss on divestiture of $0.7 million.
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 30, 2017,March 28, 2020, 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 28, 2020, the impact of cash flow hedges in the respective periods were insignificant.
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, with units being relieved andgoods. The majority of our inventory is charged to cost of sales on a first-in, first-out basis.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. Costs under long-term contracts are accumulated into, and removed from, inventory on the same basis as other contracts. 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. The majority of our revenues are recognized over time, however, 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.
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 goods soldsales using the units of delivery method.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 improvementschanges in manufacturing efficiency, reductions in 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 record additionaladjust the provisions for estimated losses on contracts. The provision for estimated losses on contracts is 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 requires 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 agreements and programs that can span several years. We recognize revenue when control of the promised goods or services is transferred to our customers, in an amount that reflects the consideration to which we expect to be entitled to in exchange for those goods or services. We apply a five-step approach as defined in the new standard in determining the amount and timing of revenue to be recognized: (1) identifying the contract with a customer; (2) identifying the performance obligations in the contract; (3) determining the transaction price; (4) allocating the transaction price to the performance obligations in the contract; and (5) recognizing revenue when the corresponding performance obligation is satisfied.
Orders for our products generally correspond to the production schedules of our customers and are supported with purchase orders with firm fixed price and firm delivery dates. Our customers have continuous control of the work in progress and finished goods throughout the manufacturing process, as these are built to customer specifications with no alternative use, and there is an enforceable right to payment for work performed to date. As a result, we recognize revenue over time based on the extent of progress towards completion of the performance obligation. Revenue recognized is based on the cost-to-cost method as it best depicts the transfer of control to our customer which takes place as we incur costs. Under the cost-to-cost measure of progress, the extent of progress toward completion is measured based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligation. Revenues are recorded proportionally as costs are incurred.
From time to time, we recognize revenue at a point in time upon transfer of control of the products to the customer. Point in time recognition was determined as the customer does not simultaneously receive or consume the benefits provided by our performance and the asset being manufactured has alternative uses to us.
Each distinct promise to transfer products is considered an identified performance obligation for which revenue is recognized upon transfer of control of the products to our customer. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied. The majority of our contracts have a single performance obligation as the promise to transfer the individual good or service is not separately identifiable from other promises in the contract and is, therefore, not distinct.
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. Net cumulative catch up adjustments on profit recorded were not material during the three months ended for both March 28, 2020 and March 30, 2019.
Contract Assets and Contract Liabilities
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 work performed but not yet billed. Similarly, when we receive payment before we ship our products to our customer, a contract liability is created for the advance or progress payment.
Contract assets consist of our right to payment for work performed but not yet billed. Contract assets are transferred to accounts receivable when we bill our customers. We bill our customers when we ship the products 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.

Recently Issued Accounting Standards
In August 2017,March 2020, the FASB issued ASU 2017-12, “Derivatives and Hedging2020-04, “Reference Rate Reform (Topic 815): Targeted Improvements to Accounting for Hedging”848), Facilitation of the Effects of Reference Rate Reform on Financial Reporting” (“ASU 2017-12”2020-04”), which intendsprovides optional guidance for a limited time for contracts that reference London Interbank Offered Rate (“LIBOR”), to improve and simplify accounting rules around hedge accounting. ASU 2017-12 refines and expands hedgeease the potential burden in accounting for, bothor recognizing the effects, of reference rate reform on financial (i.e., interest rate) and commodity risks. In addition, it creates more transparency around how economic results are presented, both on the facereporting as a result of the financial statements and in the footnotes.cessation of LIBOR. The new guidance is effective for annual periods beginningat any time after March 12, 2020 but no later than 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 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 is effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods, which will be our interim period beginning January 1, 2018. Early adoption is permitted, including adoption in any interim period. The amendments should be applied prospectively to an award modified on or after the adoption date. We are evaluating the impact of this standard.
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 require 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 is effective for annual periods beginning after

December 15, 2017, including interim periods within those annual periods, which will be our interim period beginning January 1, 2018. 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.

The amendments in ASU 2016-20 represent changes to make minor corrections or minor improvements to the Codification that are not expected to have a significant effect on current accounting practice or create a significant administrative cost to most entities. The new guidance is effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods, which will be our interim period beginning January 1, 2018. We are evaluating the impact of this standard.
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 amendments are intended to address implementation issues and provide additional practical expedients to reduce the cost and complexity of applying the new revenue standard. The new guidance is effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods, which will be our interim period beginning January 1, 2018. Early adoption is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods with that reporting period. We are evaluating the impact of this standard.
In 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”), which clarifies revenue and expense recognition for freight costs, accounting for shipping and handling fees and costs, and accounting for consideration given by a vendor to a customer. The new guidance is effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods, which will be our interim period beginning January 1, 2018. Early adoption is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods with that reporting period. We are evaluating the impact of this standard.
In April 2016, the FASB issued ASU 2016-10, “Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing” (“ASU 2016-10”), which clarifies the following two aspects of Topic 606: (a) identifying performance obligations; and (b) the licensing implementation guidance. The amendments do not change the core principle of

the guidance in Topic 606. The new guidance is effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods, which will be our interim period beginning January 1, 2018. Early adoption is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods with that reporting period. 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.accounting. The new guidance is effective for fiscal years beginning after December 15, 2018,2020, including interim periods within those fiscal years, which will be our interim period beginning January 1, 2019.2021. Early adoption is permitted. We are evaluating the impact of this standard and currently anticipate it will impact our condensed consolidated financial statements.standard.
In May 2014,August 2018, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers2018-14, “Compensation - Retirement Benefits - Defined Benefit Plans - General (Topic 606)”715-20): Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans” (“ASU 2014-09”2018-14”), which outlines a new, single comprehensive model for entities to use in accounting for revenue arising from contracts with customerswill remove disclosures that no longer are considered cost-beneficial, clarify the specific requirements of disclosures, 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 requires entities to exercise judgment when considering the terms of the contract(s) which include (i) identifying the contract(s) with the customer, (ii) identifying the separate performance obligations in the contract, (iii) determining the transaction price, (iv) allocating the transaction price to the separate performance obligations, and (v) recognizing revenue when each performance obligation is satisfied. Thus, 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. In August 2015, the FASB issued ASU 2015-14, “Revenue From Contracts With Customers (Topic 606)” (“ASU 2015-14”), which deferred the effective date of ASU 2014-09 by one year to annual periods beginning after December 15, 2017, including interim reporting periods within that reporting period. Early adoption is permitted onlyadd disclosure requirements identified as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period.relevant. The new guidance is effective for usfiscal years beginning after December 15, 2020, including interim periods within those fiscal years, which will be our interim period beginning January 1, 2018 and provides us additional time to evaluate2021. Early adoption is permitted. We are evaluating the impact that ASU 2014-09 will have on our condensed consolidated financial statements. We are in the process of completing the implementation phase of the project. We have noted that under ASU 2014-09, the percentage of completion, unit of delivery method of recognizing revenue is no longer a viable method for us and production costs will generally not be deferred. Instead, revenue will be recognized as the customer obtains control of the goods and services promised in the contract (i.e., performance obligations). Given the nature of our products and terms and conditions in the majority of our contracts, our customer obtains control as we perform work under the contract. As such, most of our revenues will be recognized sooner as a result of changing to an over time method (i.e., cost-to-cost plus a reasonable profit) from a point-in-time method, which is our current method for recognizing revenue. This will result in eliminating the majority of our work-in-process and finished goods inventory and a significant increase in unbilled accounts receivables (i.e., contract assets). This change will also impact our information technology systems, systems of internal controls over financial reporting, and certain accounting policies, requiring the usage of more judgement in determining our revenue recognition. Further, we have selected a software solution and are in the process of implementing the software solution to comply with this new accounting standard. Finally, we will adopt the new accounting standard using the modified retrospective method, under which the cumulative effect of initially 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 2018.

The intangible assets acquired of $22.4$37.2 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 value for the trade namenames and trademarks was assessed using the relief from royalty methodology. Further, we analyzed the technology acquired and concluded no fair value should be assigned to it.
The goodwill of $34.9$34.8 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, and an acquired assembled workforce.

Note 3. Restructuring Activities
Summary of 2015 Restructuring Plans
In September 2015, management approved and commenced implementation of several restructuring actions, including organizational re-alignment, consolidation and relocation of the New York facilities that was completed in December 2015, closure of the Houston facility that was completed in December 2015, and closure of the St. Louis facility that was completed in April 2016, all of which are part of our overall strategy to streamline operations. We have recorded cumulative expenses of $2.2 million for severance and benefits and loss on early exit from leases, which were charged to selling, general and administrative expenses. We do not expect to record additional expenses related to these restructuring plans.
As of September 30, 2017, we have accrued $0.4 million for loss on early exit from a lease in the Structural Systems segment.

Summary of 2016 Restructuring Plan
In May 2016, management approved and commenced implementation of the closure of one of our Tulsa facilities that was completed in June 2016, and was part of our overall strategy to streamline operations. We have recorded cumulative expenses of $0.2 million for severance and benefits and loss on early exit from a lease, which were charged to selling, general and administrative expenses. We do not expect to record additional expenses related to this restructuring plan.
As of September 30, 2017, we have accrued $0.1 million for loss on early exit from a lease in the Electronic Systems segment.

Summary of 2017 Restructuring Plan
Subsequent to our quarter ended September 30, 2017, in November 2017, management approved and commenced a restructuring plan that is expected to increase operating efficiencies. We currently estimate this initiative will result in $22.0 million to $25.0 million in total pre-tax restructuring charges through 2018, with an estimate of $10.5 million to be recorded during the fourth quarter of 2017. Of these charges, we estimate $9.0 million to $10.0 million are expected to be cash payments for employee separation and other consolidation related expenses with the remaining $13.0 million to $15.0 million expected to be non-cash charges for write-down of inventory and impairment of long-lived assets. On an annualized basis, beginning in 2019, we estimate these restructuring actions will result in total savings of $14.0 million.


Note 4. 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. Assets and liabilities measured at fair value on a recurring basis were as follows (in thousands):

There were no transfers between Level 1, Level 2, or Level 3 financial instruments in the three months ended September 30, 2017.

Note 5. Financial Instruments
Derivative Instruments and Hedging Activities
We periodically enter into cash flow derivative transactions, such as interest rate cap agreements, to hedge exposure to various risks related to interest rates. We assess the effectiveness of the interest rate cap hedges at inception of the hedge. We recognize all derivatives at their fair value. For cash flow designated hedges, the effective portion of the changes in fair value of the derivative contract are recorded in accumulated other comprehensive income (loss), net of taxes, and are recognized in net earnings at the time earnings are affected by the hedged transaction. Adjustments to record changes in fair values of the derivative contracts that are attributable to the ineffective portion of the hedges, if any, are recognized in earnings. We present derivative instruments in our condensed consolidated statements of cash flows’ operating, investing, or financing activities consistent with the cash flows of the hedged item.
Our interest rate cap hedges were designated as cash flow hedges and deemed highly effective at the inception of the hedges. These interest rate cap hedges mature concurrently with the term loan in June 2020. During the three months ended September 30, 2017, the interest rate cap hedges continued to be highly effective and zero, net of tax, was recognized in other comprehensive income. No amount was recorded in the condensed consolidated income statements during the three months ended September 30, 2017. See Note 9.

As an accounting policy election chose 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).
We have operating and finance leases for manufacturing facilities, corporate offices, and various equipment. Our leases have remaining lease terms of 1 year to 11 years, some of which include options to extend the leases for up to 5 years, and some of which include options to terminate the leases within 1 year.

Note 7.5. Goodwill
We perform our annual goodwill impairment test duringas of the first day of the fourth quarter. If certain factors occur, we may have to perform an impairment test prior to the fourth quarter 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.differently, we may perform an impairment test prior to the fourth quarter.
As a result of the outbreak of the COVID-19 pandemic during the three months ended March 28, 2020, which impacts our business in the United States and the rest of the world, we assessed our goodwill for potential impairment indicators. The most recent goodwill impairment test for our Electronic Systems reporting unit was the annual goodwill impairment test as of the first day of the fourth quarter of 2019 where the fair value of our Electronic Systems reporting unit exceeded its carrying value by 44% and thus, goodwill was not deemed impaired at that time. For the first quarter of 2020, we performed a qualitative assessment including consideration of 1) margin of passing most recent Step 1 analysis, 2) earnings before interest, taxes, depreciation, and amortization, 3) long-term growth rate, 4) analyzing material adverse factors/changes between valuation

dates, 5) general macroeconomic factors, and 6) industry and market conditions. We determined it was not more likely than not that the fair value of a reporting unit is less than its carrying amount and thus, goodwill was not deemed impaired.
The most recent Step 1 goodwill impairment test for our Structural Systems reporting unit was April 2019, where the fair value of our Structural Systems reporting unit exceeded its carrying value by 85%. As such, for our annual goodwill impairment test as of the first day of the fourth quarter of 2019, we used a qualitative assessment and determined it was not more likely than not that the fair value of a reporting unit is less than its carrying amount and thus, goodwill was not deemed impaired at that time. For the first quarter of 2020, we performed a qualitative assessment including consideration of 1) margin of passing most recent step 1 analysis, 2) earnings before interest, taxes, depreciation, and amortization, 3) long-term growth rate, 4) analyzing material adverse factors/changes between valuation dates, 5) general macroeconomic factors, and 6) industry and market conditions. We determined it was not more likely than not that the fair value of a reporting unit is less than its carrying amount and thus, goodwill was not deemed impaired.

OurOn December 20, 2019, we completed the refinancing of a portion of our existing debt by entering into a new revolving credit facility consists of(“New Revolving Credit Facility”) to replace the existing revolving credit facility that was entered into in November 2018 (“2018 Revolving Credit Facility”) and entering into a $275.0 million senior securednew term loan which matures on June 26, 2020 (“New Term Loan”), and. The New Revolving Credit Facility is a $200.0$100.0 million senior secured revolving credit facility (“that matures on December 20, 2024 replacing the $100.0 million 2018 Revolving Credit Facility”), whichFacility that would have matured on November 21, 2023. The New Term Loan is a $140.0 million senior secured term loan that matures on June 26, 2020December 20, 2024. We also have an existing $240.0 million senior secured term loan that was entered into in November 2018 that matures on November 21, 2025 (“2018 Term Loan”). The original amounts available under the New Revolving Credit Facility, New Term Loan, and 2018 Term Loan (collectively, the “Credit Facilities”). in aggregate, totaled $480.0 million.
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 1.50% to 2.50% 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% to 1.50% 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 1.25% of the original outstanding principal balance of the New Term Loan amount on a quarterly basis.

In addition, the 2018 Term Loan requires installment payments of 0.25% of the outstanding principal balance of the 2018 Term Loan amount on a quarterly basis.
Further, under the Credit Facilities, if we aremeet the annual excess cash flow threshold, we will be required to make excess 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

The loans under the Revolving Credit Facility are due on June 26, 2020.required 2019 annual excess cash flow payment of $7.4 million. As of September 30, 2017,March 28, 2020, we were in compliance with all covenants required under the Credit Facilities.
We have been making periodic voluntary principal prepayments on our credit facilities, however, during the three months ended March 28, 2020, as a result of drawing down $50.0 million on the New Revolving Credit Facility to hold as cash, we made no net aggregate voluntary prepayments.
In addition,conjunction with entering into the New Revolving Credit Facility and the New Term Loan, we incurred $4.8drew down the entire $140.0 million on the New Term Loan and used those proceeds to pay off and close the 2018 Revolving Credit Facility of $58.5 million, pay down a portion of the 2018 Term Loan of $56.0 million, pay the accrued interest associated with the amounts being paid down on the 2018 Revolving Credit Facility and 2018 Term Loan, pay the fees related to this transaction, and the remainder will be used for general corporate expenses. The New Revolving Credit Facility does not require any principal installment payments, however, the undrawn portion is subject to a commitment fee ranging from 0.175% to 0.275%, based upon the consolidated total net adjusted leverage ratio. The New Term Loan requires installment payments of 1.25% of the initial principal balance outstanding on a quarterly basis. The $56.0 million pay down paid all the required quarterly principal installment payments on the 2018 Term Loan until it matures.
The New Term Loan and 2018 Term Loan were considered a modification of debt issuance costs relatedand thus, no gain or loss was recorded. Instead, the new fees paid to the Credit Facilities and those costslenders of $0.6 million were capitalized and are being amortized over the five year life of the Credit Facilities.
On July 14, 2017, we entered into a technical amendmentNew Term Loan. The remaining debt issuance costs related to the Credit Facilities (“First Amendment”) which provides more flexibility to close certain qualified acquisitions permitted under the Credit Facilities.

As a result, we expensed the portion of the unamortized debt issuance costs related to the 2018 Revolving Credit Facility that was considered an extinguishment of debt of $0.5 million.

In October 2019, we acquired LDS100.0% of the outstanding equity interests of Nobles for aan original purchase price of $60.0$77.0 million, net of cash acquired, all payable in cash. Upon the closing of the transaction, we paid $61.4a gross total aggregate of $77.3 million in cash upon the closing of the transaction 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 the2018 Revolving Credit Facility. See Note 2 for further information.2.
As of September 30, 2017,March 28, 2020, we had $134.5$49.8 million of unused borrowing capacity under the Revolving Credit Facility, after deducting $64.7 million for draw down on the Revolving Credit Facility and $0.8$0.2 million for standby letters of credit.
The Credit Facilities were entered into by us (“Parent Company”) and guaranteed by all of our domestic subsidiaries, other than one subsidiary2 subsidiaries that were considered minor (“Subsidiary Guarantors”) that was considered minor.. The Subsidiary Guarantors jointly and severally guarantee the 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 2016, we entered into an agreement to purchase $9.9 million of industrial revenue bonds (“IRBs”) issued by the city of Parsons, Kansas (“Parsons”) and concurrently, sold $9.9 million of property and equipment (“Property”) to Parsons as well as entered into a lease agreement to lease the Property from Parsons (“Lease”) with lease payments totaling $9.9 million over the lease term. The sale of the Property and concurrent lease back of the Property did not meet the sale-leaseback accounting requirements as a result of our continuous involvement with the Property and thus, the $9.9 million in cash received from Parsons was not recorded as a sale but as a financing obligation. Further, the Lease included a right of offset and thus, the financing obligation of $9.9 million was offset against the $9.9 million of IRBs assets and presented net on the condensed consolidated balance sheets with no impact to the condensed consolidated income statements or condensed consolidated cash flow statements.

Note 12.9. 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 or theunder 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 indefinite but 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 fair valueamount of our indemnification obligations as insignificant based on this history and insurance coverage and therefore, have therefore, 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 13.10. 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 and deductions available for domestic production activities.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, using enacted tax rates, 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.
We recorded income tax expense of $0.9$1.5 million (effective tax rate of 16.8%) for the three months ended September 30, 2017March 28, 2020 compared to $1.2$1.0 million (effective tax rate of 19.8%) for the three months ended October 1, 2016.March 30, 2019. The decreaseincrease in the effectiveincome tax rateexpense for the three months ended September 30, 2017first quarter of 2020 compared to the three months ended October 1, 2016first quarter of 2019 was primarily due to tax benefits recognized from additional U.S. Federal research and development tax credits. FASB ASU 2016-09 became effective beginning January 1, 2017 and required all the tax effects related to share-based payments be recorded through thehigher pre-tax income statement. This could result in fluctuations in our effective tax rate from period to period, depending on the number of awards exercised and/or vested in the quarter as well as the volatility of our stock price. During the current year three month period, we recognized tax benefits from deductions of share-based payments in excess of compensation cost recognized for financial reporting purposes of $0.1 million, which decreased our effective tax rate by 0.6%.
We recorded income tax expense of $2.1 million (effective tax rate of 16.4%) for the nine months ended September 30, 2017 compared to $9.9 million (effective tax ratefirst quarter of 30.5%) for the nine months ended October 1, 2016. The decrease in the effective tax rate for the nine months ended September 30, 20172020 compared to the nine months ended October 1, 2016 was primarily duefirst quarter of 2019. On March 27, 2020, the U.S. enacted the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) that provides tax relief to individuals and businesses affected by the preliminary gain on divestiturescoronavirus pandemic. We considered the provisions of the CARES Act and determined they do not have a material impact to our Pittsburgh and Miltec operations of $18.8 million, which resulted in a higher state tax liability, compared to the current year nine month period. In addition, during the current year nine month period, we

recognized tax benefits from deductions of share-based payments in excess of compensation cost recognized for financial reporting purposes of $0.6 million, which decreased the effective tax rate by 4.8%, and we recognized additional tax benefits from U.S. Federal research and development tax credits.income taxes.
Our total amount of unrecognized tax benefits was $3.7$5.8 million and $3.0$5.7 million as of September 30, 2017March 28, 2020 and December 31, 2016,2019, respectively. If recognized, $2.4$4.1 million would affect the effective tax rate. We do not reasonablyAs a result of statute of limitations set to expire in the fourth quarter of 2020, we expect significant increases or decreases to our unrecognized tax benefits of approximately $2.0 million in the next twelve months.
In 2016, the Internal Revenue Service (“IRS”) commenced an audit of our 2014 and 2015 tax years. Although the outcome of tax examinations cannot be predicted with certainty, we believe we have adequately accrued for tax deficiencies or reductions in tax benefits, if any, that could result from the examination and all open audit years.

Note 14.11. 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 30, 2017March 28, 2020 and December 31, 2016,2019, 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 30, 2017,March 28, 2020, 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.
ThirdCOVID-19 Coronavirus Pandemic Impact on Our Business
The outbreak of the COVID-19 coronavirus has been declared a pandemic by the World Health Organization during our first quarter 2017of 2020 but did not have a significant impact to our overall business during the three months ended March 28, 2020. However, during the latter part of our first quarter and subsequent to our quarter end, the COVID-19 pandemic has grown, causing non-essential businesses to shut down and many people to observe the shelter-in-place directive from our government. The COVID-19 pandemic is beginning to contribute to a general slowdown in the global economy and if it continues for an extended period of time, it could adversely impact the businesses of our customers and suppliers, as well as our results of operations and financial condition for some portion, if not the remainder, of 2020. See Risk Factors included in Part II, Item 1A of this Form 10-Q.
First quarter 2020 highlights:
Revenues of $138.7$173.5 million
Net income of $4.7$7.9 million, or $0.41$0.67 per diluted share
Adjusted EBITDA of $14.5$23.2 million
Backlog of $655.3 million
Completed the acquisition of Lightning Diversion Systems, LLC
Non-GAAP Financial Measures
Adjusted earnings before interest, taxes, depreciation, amortization, and restructuring chargesstock-based compensation expense (“Adjusted EBITDA”) was $14.5$23.2 million and $14.9$21.1 million for the three months ended SeptemberMarch 28, 2020 and March 30, 2017 and October 1, 2016,2019, 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;
22

Table of Contents
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; and
Stock-based compensation may be useful to our investors for determining current cash flow;
Gain on divestitures may be useful to our investors in evaluating our on-going operating performance; and
Restructuring charges may be useful to our investors in evaluating our core operating performance.flow.

Net revenues for the three months ended September 30, 2017March 28, 2020 were $138.7$173.5 million, compared to $132.6$172.6 million for the three months ended October 1, 2016.March 30, 2019. The year-over-year increase was primarily due to the following:
$8.124.2 million higher revenues in our military and space end-use markets mainly due to increased demand, which favorably impacted ourhigher build rates on military fixed-wing aircraft platforms, various missile platforms, and helicopterother military and space platforms; and
$0.9 million higher revenues in our industrial end-use markets; partially offset by
$2.823.0 million lower revenues in our commercial aerospace end-use markets mainly due to the winding down of a regional jet program and continued softness in demand within the business jet market.
Net revenues for the nine months ended September 30, 2017 were $415.9 million, compared to $408.2 million for the nine months ended October 1, 2016. The year-over-year increase was primarily due to the following:
$31.9 million higher revenues in our military and space end-use markets mainly due to increased demand, which favorably impacted our helicopter and fixed-wing platforms, partially offset by the divestiture of our Miltec operation in March 2016. The net increase was partially offset by
$16.8 million lower revenues in our commercial aerospace end-use markets mainly due to the winding down of a regional jet program and continued softness in demand within the business jet market; and
$7.4 million lower revenues in our industrial end-use markets mainly due to exiting certain Industrial customers and the divestiture of our Pittsburgh operation in January 2016.

(2)Includes The Boeing Company (“Boeing”), Northrop Grumman Corporation (“Northrop”), Raytheon Company (“Raytheon”), Spirit Aerosystems Holdings, Inc. (“Spirit”), and United Technologies Corporation (“United Technologies”). The significant decrease in total aggregate revenues generated from our top ten customers was primarily due to the decrease by Boeing and Spirit, mainly due to the impact from the continued grounding of the Boeing 737 MAX program combined with the outbreak of the COVID-19 pandemic during our first quarter of 2020, which resulted in the March 23, 2020 and March 24, 2020 announcements by Boeing and Spirit, respectively, to temporarily shut down production at some of their facilities. However, subsequent to our quarter end, Boeing resumed production at two of their manufacturing facilities.

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 decreasedincreased year-over-year in the three months ended September 30, 2017March 28, 2020 to 18.8%21.2%, compared to the three months ended October 1, 2016March 30, 2019 of 19.0% primarily20.7% due to unfavorable product mix, partially offset by lower manufacturing costs as a result of ongoing cost reduction initiatives.

Selling, General and Administrative (“SG&A”) Expenses
SG&A expenses increased $1.6$0.3 million year-over-year in the three months ended September 30, 2017March 28, 2020 compared to the three months ended October 1, 2016 primarilyMarch 30, 2019 due to higher compensation and benefit costsother corporate expenses of $1.5 million.
SG&A expenses increased $0.6 million year-over-year in the nine months ended September 30, 2017 compared to the nine months ended October 1, 2016 primarily due to higher compensation and benefit costs of $2.0 million, partially offset by a decrease due to the divestitureslower professional services fees of our Pittsburgh and Miltec operations and closure of certain facilities of $1.3$0.4 million.

Interest expense increased year-over-yeardecreased in the three months ended September 30, 2017March 28, 2020 compared to the three months ended October 1, 2016 primarilyMarch 30, 2019 due to lower interest rates, partially offset by a higher utilizationoutstanding balance on the Credit Facilities driven by the acquisition of Nobles Worldwide, Inc. (“Nobles”) in October 2019, and higher net draw down on the Revolving Credit Facility, balance in the current three month period, including the acquisition of Lightning Diversion Systems, LLC (“LDS”), partially offset by a lower Term Loan balance$50.0 million as a result of voluntary principal prepaymentscash on our credit facilities.
Interest expense decreased year-over-year in the nine months ended September 30, 2017 compared to the nine months ended October 1, 2016 primarily due to a lower outstanding Term Loan balance as a result of voluntary principal prepayments on our credit facilities, partially offset by higher utilization of the Revolving Credit Facility in the current nine month period, including the acquisition of LDS.

Gain on Divestitures
There was no gain on divestitures during the three and nine months ended September 30, 2017. The gain on divestitures for the three and nine months ended October 1, 2016 consisted of the divestitures during the first quarter of 2016 of our Pittsburgh operation with a pretax gain of $18.3 million and our Miltec operation with a preliminary pretax gain of $0.5 million. (see Note 1 to our condensed consolidated financial statements included in Part I, Item 1 of this Form 10-Q).hand.
Income Tax Expense
We recorded income tax expense of $0.9$1.5 million (effective tax rate of 16.8%) for the three months ended September 30, 2017March 28, 2020 compared to $1.2$1.0 million (effective tax rate of 19.8%) for the three months ended October 1, 2016.March 30, 2019. The decreaseincrease in the effectiveincome tax rateexpense for the three months ended September 30, 2017first quarter of 2020 compared to the three months ended October 1, 2016first quarter of 2019 was primarily due to tax benefits recognized from additional U.S. Federal research and development tax credits. FASB ASU 2016-09 “Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting” became effective beginning January 1, 2017 and required all of the tax effects related to share-based payments to be recorded through thehigher pre-tax income statement. This could result in fluctuations in our effective tax rate from period to period, depending on the number of awards exercised and/or vested in the quarter as well as the volatility of our stock price. During the current year three month period, we recognized tax benefits from deductions of share-based payments in excess of compensation cost recognized for financial reporting purposes of $0.1 million, which decreased the effective tax rate by 0.6%.
We recorded income tax expense of $2.1 million (effective tax rate of 16.4%) for the nine months ended September 30, 2017 compared to $9.9 million (effective tax ratefirst quarter of 30.5%) for the nine months ended October 1, 2016. The decrease in the effective tax rate for the nine months ended September 30, 20172020 compared to the nine months ended October 1, 2016 was primarily duefirst quarter of 2019. On March 27, 2020, the U.S. enacted the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) that provides tax relief to individuals and businesses affected by the preliminary gain on divestiturescoronavirus pandemic. We considered the provisions of the CARES Act and determined they do not have a material impact to our Pittsburgh and Miltec operations of $18.8 million, which resulted in a higher state tax liability, compared to the current nine month period. In addition, during the current nine month period, we recognized tax benefits from deductions of share-based payments in excess of compensation cost recognized for financial reporting purposes of $0.6 million, which decreased the effective tax rate by 4.8%, and we recognized additional tax benefits from U.S. Federal research and development tax credits.income taxes.
Our total amount of unrecognized tax benefits was $3.7$5.8 million and $3.0$5.7 million as of September 30, 2017March 28, 2020 and December 31, 2016,2019, respectively. If recognized, $2.4$4.1 million would affect the effective tax rate. We do not reasonablyAs a result of statute of limitations set to expire in the fourth quarter of 2020, we expect significant increases or decreases to our unrecognized tax benefits of $2.0 million in the next twelve months.
In 2016, the Internal Revenue Service (“IRS”) commenced an audit of our 2014 and 2015 tax years. Although the outcome of tax examinations cannot be predicted with certainty, we believe we have adequately accrued for tax deficiencies or reductions in tax benefits, if any, that could result from the examination and all open audit years.
Net Income and Earnings per Share
Net income and earnings per share for the three months ended September 30, 2017March 28, 2020 were $4.7$7.9 million, or $0.41$0.67 per diluted share, compared to $5.0$7.5 million, or $0.44$0.64 per diluted share, for the three months ended October 1, 2016.March 30, 2019. The decreaseincrease in net income for the three months ended September 30, 2017March 28, 2020 compared to the three months ended October 1, 2016March 30, 2019 was primarily due to the following:
$1.6 million higher SG&A expense; partially offset by
$0.3$1.1 million of higher gross profit as a result of higher revenues and lower income tax expense.compensation and benefit costs.
Net income and earnings per share for the nine months ended September 30, 2017 were $10.6 million, or $0.92 per diluted share, compared to $22.4 million, or $1.99 per diluted share, for the nine months ended October 1, 2016. The decrease in net income for the nine months ended September 30, 2017 compared to the nine months ended October 1, 2016 was primarily due to the following:

$1.6 million lower revenues in our commercial aerospace end-use markets mainly due to the winding down of a regional jet program and continued softness in demand within the business jet market; partially offset by
$0.312.9 million higher revenues in our military and space end-use markets mainly due to higher build rates on military fixed-wing aircraft platforms and various missile platforms, partially offset by lower build rates on other military and space platforms; and
$1.4 million higher revenues in our commercial aerospace end-use markets due to higher build rates on other commercial aerospace platforms.

Backlog
We define backlog as customer placed purchase orders (“POs”) and long-term agreements (“LTAs”) with firm fixed price and expected 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 remaining 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 3-monththree 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. $427.0
The decrease in backlog was primarily in the commercial aerospace end-use markets, mainly due to the COVID-19 pandemic, partially offset by an increase in the military and space end-use markets. $587.0 million of total backlog is expected to be delivered over the next 12 months. The following table summarizes our backlog as of September 30, 2017March 28, 2020 and December 31, 2016:2019:

OurOn December 20, 2019, we completed the refinancing of a portion of our existing debt by entering into a new revolving credit facility consists of(“New Revolving Credit Facility”) to replace the existing revolving credit facility that was entered into in November 2018 (“2018 Revolving Credit Facility”) and entering into a $275.0 million senior securednew term loan which matures on June 26, 2020 (“New Term Loan”), and. The New Revolving Credit Facility is a $200.0$100.0 million senior secured revolving credit facility (“that matures on December 20, 2024 replacing the $100.0 million 2018 Revolving Credit Facility”), whichFacility that would have matured on November 21, 2023. The New Term Loan is a $140.0 million senior secured term loan that matures on June 26, 2020December 20, 2024. We also have an existing $240.0 million senior secured term loan that was entered into in November 2018 that matures on November 21, 2025 (“2018 Term Loan”). The original amounts available under the New Revolving Credit Facility, New Term Loan, and 2018 Term Loan (collectively, the “Credit Facilities”). in aggregate, totaled $480.0 million. We are required to make mandatory prepaymentsinstallment payments of amounts1.25% of the original 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 0.175% to 0.275%, based upon the consolidated total net adjusted leverage ratio. As of September 30, 2017,As of March 28, 2020, we were in compliance with all covenants required under the Credit Facilities. See Note 97 to our condensed consolidated financial statements included in Part I, Item 1 of this Form 10-Q for further information. On July 14, 2017,
In November 2018, we entered intocompleted credit facilities to replace the then existing credit facilities. The November 2018 credit facilities consisted of the 2018 Term Loan and the 2018 Revolving Credit Facility (collectively, the “2018 Credit Facilities”). We are required to make installment payments of 0.25% of the outstanding principal balance of the 2018 Term Loan amount on a technical amendmentquarterly basis. In addition, if we meet the annual excess cash flow threshold, we will be required to the Credit Facilities (“First Amendment”) which provides more flexibilitymake excess flow payments on an annual basis. See Note 7 to close certain qualified acquisitions permittedour condensed consolidated financial statements included in Part I, Item 1 of this Form 10-Q for further information. We made an aggregate total of $7.4 million of voluntary and mandatory principal prepayments under the Credit Facilities.Term Loans during the three months ended March 28, 2020.
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.
On September 11, 2017,In October 2019, we acquired LDSNobles Parent Inc., the parent company of Nobles Worldwide, Inc. (“Nobles”) for aan original purchase price of $60.0$77.0 million, net of cash acquired, all payable in cash. UponWe paid a gross total aggregate of $77.3 million in cash upon the closing of the transaction we paid $61.4 million in cash by drawing down on the Revolving Credit Facility.

We expect to spend a total of $26.0$12.0 million to $30.0$14.0 million for capital expenditures in 20172020 financed by cash generated from operations, principally to support the expansion of our Parsons, Kansas facility and new contract awards atin Electronic Systems and Structural Systems

and Electronic 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. However, some portion of the expected capital expenditures in 2020 could be delayed as a result of the COVID-19 pandemic.
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 Credit Facilities to provide short-term liquidity. Cash generated from operations and bank borrowing capacity isare expected to provide sufficient liquidity to meet our obligations during the next twelve months.

Item 3. Quantitative and Qualitative Disclosures About Market Risk
Our main market risk exposure relates to changes in U.S. and U.K. interest rates on our outstanding long-term debt. At September 30, 2017,March 28, 2020, we had total borrowings of $224.7$352.6 million under our Credit Facilities.
The New Term Loan and Revolving Credit Facility that bearbears interest, at our option, at a rate equal to either (i) the Eurodollar Rate (defined as LIBOR)the London Interbank Offered Rate [“LIBOR”]) plus an applicable margin ranging from 1.50% to 2.75%2.50% 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% to 1.75%1.50% per year, in each case based upon the consolidated total net adjusted leverage ratio.
The New Revolving Credit Facility 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% to 2.50% 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% to 1.50% per year, in each case based upon the consolidated total net adjusted leverage ratio.
A hypothetical 10% increase or decrease in the interest rate would have an immaterial impact on our financial condition and results of operations.

Item 4. Controls and Procedures
Disclosure Controls and Procedures
The Company’s chief executive officer (“CEO”) and chief financial officer (“CFO”) have conducted an evaluation of the Company’s disclosure controls and procedures (as defined in the Securities Exchange Act of 1934 Rules 13a-15(e) and 15d-15(e)) as of September 30, 2017. The Company had previously reported a material weakness in internal control over

financial reporting related to not maintaining effective controls related to the quarterly, and annual accounting and disclosures for income taxes. This material weakness was described in Item 9A in the Management’s Report on Internal Control Over Financial Reporting in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016. As a result of the material weakness in the Company’s internal control over financial reporting, which was not remediated as of September 30, 2017, the CEO and CFO concluded the Company’sthat such disclosure controls and procedures were not effective as of September 30, 2017.the end of the period covered by this report.
Management’s Remediation Activities
30

We are committed to remediating the control deficiencies that constitute the material weakness described above. Our Chief Financial Officer is responsible for remediating the control deficiency that gave rise to the material weakness.
Actions to be taken or in process consistTable of ensuring we maintain a sustained period of operating effectiveness of our internal control over financial reporting related to the quarterly and annual accounting and disclosures for income taxes.Contents
While significant progress has been made to enhance our internal control over financial reporting relating to the material weakness, additional time will be required to assess and ensure the sustainability of these processes and procedures. We expect the remedial actions described above will have had sufficient time to function during 2017 to allow management to conclude that the material weakness has been satisfactorily remediated and that the existing controls are operating effectively. However, we cannot make any assurances that such actions will be completed during 2017. Until the controls described above have had sufficient time for management to conclude that they are operating effectively, the material weakness described above will continue to exist.
Changes in Internal Control over Financial Reporting
There were no changes in our internal controlscontrol over financial reporting during the three months ended September 30, 2017March 28, 2020 that have materially affected, or are reasonably likely to materially affect, our internal controlscontrol over financial reporting.

Item 1. Legal Proceedings
See Note 1411 to our condensed consolidated financial statements included in Part I, Item 1 of this Form 10-Q for a description of our legal proceedings.


Item 1A. Risk Factors
See Part I, Item 1A of our Annual Report on Form 10-K for the year ended December 31, 20162019 for a discussion of our risk factors. ThereOther than the risk factor below, there have been no material changes in the ninethree months ended September 30, 2017March 28, 2020 to the risk factors disclosed in our Annual Report on Form 10-K for the year ended December 31, 2016.2019.

The outbreak of the COVID-19 coronavirus could have a material adverse effect on our business, results of operations and financial condition.
In recent weeks, the COVID-19 coronavirus pandemic has caused significant volatility in financial markets, including the market price of our stock, and the commercial aerospace industry, which has raised the prospect of an extended global recession. Public health problems resulting from COVID-19 and precautionary measures instituted by governments and businesses to mitigate its spread, including travel restrictions and quarantines, is beginning to contribute to a general slowdown in the global economy and if it continues for an extended period of time, it could adversely impact the businesses of our customers, suppliers and distribution partners, and disrupt our operations. Changes in our operations in response to the COVID-19 pandemic or employee illnesses resulting from the pandemic, may result in inefficiencies or delays, including in sales and product development efforts and additional costs related to business continuity initiatives, that cannot be fully mitigated through succession planning, employees working remotely, or teleconferencing technologies. In addition, a prolonged economic downturn could result in reduced or delayed demand for our products. While the full extent and impact of the COVID-19 pandemic cannot be reasonably estimated with certainty at this time, it could have a material adverse impact on our business, results of operations and financial condition for some portion, if not the remainder, of 2020.
