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 subsidiaries are organized into two strategic businesses: Electronic Systems segment and Structural Systems segment, each of which is a reportable operating segment. Electronic Systems designs, engineers and manufactures high-reliability products used in worldwide technology-driven markets including aerospace, defense, industrial and medical and other end-use markets. Electronic Systems’ product offerings range from prototype development to complex assemblies. Structural Systems designs, engineers and manufactures large, complex contoured aerospace structural components and assemblies and supplies composite and metal bonded structures and assemblies. Structural Systems’ products are used on commercial aircraft, military fixed-wing aircraft and military and commercial rotary-wing aircraft. Both 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, 2016 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. 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.

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, 2017 are not necessarily indicative of the results to be expected for the full year ending December 31, 2017.

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 requires 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 are computed by dividing income available to common shareholders by the weighted-average number of common shares outstanding, plus any potential dilutive shares that could be issued if exercised or converted into common stock in each period.

The net income, weighted-average number of common shares outstanding used to compute earnings per share, were as follows:

Potentially dilutive stock options and stock units to purchase common stock, as shown below, were excluded from the computation of diluted earnings per share because their inclusion would have been anti-dilutive. However, these shares may be potentially dilutive common shares in the future.

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 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

On January 22, 2016, we entered into an agreement, and completed 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. We divested this facility as part of our overall strategy to streamline operations, which included consolidating our footprint. However, the sale of the Pittsburgh 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. Preliminary net assets sold were $24.0 million , net liabilities sold were $4.0 million , and direct transaction costs incurred were $0.2 million , resulting in a preliminary gain on divestiture of

Table of Contents

$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, 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.

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 and charged to cost of sales on a first-in, first-out basis. 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.

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 sold using the units of delivery method. 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.

Table of Contents

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 improvements 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 additional provisions for estimated losses on contracts.

Recent Accounting Pronouncements

New Accounting Guidance Adopted in 2017

In December 2016, the FASB issued ASU 2016-19, “Technical Corrections and Improvements” (“2016-19”), which cover a variety of Topics in the Codification. The amendments in ASU 2016-19 represent changes to make corrections or 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 was effective for us beginning January 1, 2017. The adoption of this standard did not have a significant impact on our condensed consolidated financial statements.

In March 2016, the FASB issued ASU 2016-09, “Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting” (“ASU 2016-09”), which is intended to improve the accounting for employee share-based payments. The new guidance was effective for us beginning January 1, 2017. The adoption of this standard did not have a significant dollar impact on our condensed consolidated financial statements.

In March 2016, the FASB issued ASU 2016-05, “Derivatives and Hedging (Topic 815): Effect of Derivative Contract Novations on Existing Hedge Accounting Relationships” (“ASU 2016-05”), which clarifies that a change in the counter party to a derivative instrument designated as a hedging instrument does not require dedesignation of that hedging relationship, provided that all other hedge accounting criteria are met. The new guidance was effective for us beginning January 1, 2017. The adoption of this standard did not have a significant impact on our condensed consolidated financial statements.

In July 2015, the FASB issued ASU 2015-11, “Inventory (Topic 330)” (“ASU 2015-11”), which requires inventory within the scope of ASU 2015-11 to be measured at the lower of cost or net realizable value. Subsequent measurement is unchanged for inventory measured using last-in, first-out (“LIFO”) or the retail inventory value. The new guidance was effective for us beginning January 1, 2017. The adoption of this standard did not have a significant impact on our condensed consolidated financial statements.

Recently Issued Accounting Standards

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 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

Table of Contents

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.

In January 2017, the FASB issued ASU 2017-01, “Business Combinations (Topic 805): Clarifying the Definition of a Business” (“ASU 2017-01”), which clarify 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 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 December 2016, the FASB issued ASU 2016-20, “Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers” (“ASU 2016-20”), which cover a variety of Topics in the Codification related to the new revenue recognition standard (ASU 2014-09). 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 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 May 2016, the FASB issued ASU 2016-12, “Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients” (“ASU 2016-12”), which amends the guidance in the new revenue standard on collectability, noncash consideration, presentation of sales tax, and transition. 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

Table of Contents

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. 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 and currently anticipate it will impact 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 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 only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. The new guidance is effective for us beginning January 1, 2018 and provides us additional time to evaluate 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.

Note 2. Business Combination

On September 11, 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 is 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. Upon the closing of the transaction, we paid $61.4 million with the remaining $0.6 million paid in October 2017, subsequent to our quarter ended September 30, 2017. We preliminarily 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 is recorded as goodwill. The allocation is subject to revision 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.

Table of Contents

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



	Estimated Fair Value
Cash	$	2,223
Accounts receivable	918
Inventories	1,732
Other current assets	54
Property and equipment	138
Intangible assets	22,400
Goodwill	34,881
Total assets acquired	62,346
Current liabilities	(325		)
Total liabilities assumed	(325		)
Total preliminary purchase price allocation	$	62,021



	Useful Life (In years)	Estimated Fair Value (In thousands)
Intangible assets:
Customer relationships	15	$	21,100
Trade name	15	1,300
		$	22,400

The intangible assets acquired of $22.4 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 name 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 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. 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.

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 $0.3 million in both the three months and nine months ended September 30, 2017 and charged to selling, general and administrative expenses.

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. Pro forma results of operations of the LDS acquisition during the three and nine months ended September 30, 2017 have not been presented as the effect of the LDS acquisition was not material to our financial results.

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.

Our restructuring activities in the nine months ended September 30, 2017 were as follows (in thousands):



	December 31, 2016		Nine Months Ended September 30, 2017							September 30, 2017

Ending balance	$	654	$	—	$	(235	)	$	64	$	483

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):



	As of September 30, 2017								As of December 31, 2016

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 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.

The recorded fair value of the derivative financial instruments on the condensed consolidated balance sheets were as follows:

We net progress payments from customers related to inventory purchases against inventories on the condensed consolidated balance sheets.

Note 7. Goodwill

We perform our annual goodwill impairment test during 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.

Our credit facility consists of a $275.0 million senior secured term loan, which matures on June 26, 2020 (“Term Loan”), and a $200.0 million senior secured revolving credit facility (“Revolving Credit Facility”), which matures on June 26, 2020 (collectively, the “Credit Facilities”). The Credit Facilities bear 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 2.75% 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% to 1.75% per year, in each case based upon the consolidated total net adjusted leverage ratio. The undrawn portions of the commitments of the Credit Facilities are subject to a commitment fee ranging from 0.175% to 0.300% , based upon the consolidated total net adjusted leverage ratio.

Further, we are required to make mandatory prepayments of amounts outstanding under the Term Loan. The mandatory prepayments will be made quarterly, equal to 5.0% per year of the original aggregate principal amount during the first two

Table of Contents

years and increase to 7.5% per year during the third year, and increase 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. As of September 30, 2017, we were in compliance with all covenants required under the Credit Facilities.

In addition, we incurred $4.8 million of debt issuance costs related to the Credit Facilities and those costs were capitalized and are being amortized over the five year life of the Credit Facilities.

On July 14, 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 made voluntary principal prepayments of zero and $10.0 million under the Term Loan during the three and nine months ended September 30, 2017, respectively.

On September 11, 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 2 for further information.

As of September 30, 2017, we had $134.5 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 million for standby letters of credit.

The Credit Facilities were entered into by us (“Parent Company”) and guaranteed by all of our subsidiaries, other than one subsidiary (“Subsidiary Guarantors”) that was considered minor. 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, 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 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. See Note 5 for further discussion.

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 10. Shareholders’ Equity

We are authorized to issue five million shares of preferred stock. At September 30, 2017 and December 31, 2016 , no preferred shares were issued or outstanding.

(1)	The amortization expense is included in the computation of periodic pension cost and is a decrease to net income upon reclassification from accumulated other comprehensive loss.

Note 12. 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 the facility or the 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 value of our indemnification obligations as insignificant based on this history and insurance coverage and have, therefore, not recorded any liability for these guarantees and indemnities on the accompanying condensed consolidated balance sheets.

Note 13. 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. 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. 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.

We recorded income tax expense of $0.9 million (effective tax rate of 16.8% ) for the three months ended September 30, 2017 compared to $1.2 million (effective tax rate of 19.8% ) for the three months ended October 1, 2016. The decrease in the effective tax rate for the three months ended September 30, 2017 compared to the three months ended October 1, 2016 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 the 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% .

Table of Contents

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.

Our total amount of unrecognized tax benefits was $3.7 million and $3.0 million as of September 30, 2017 and December 31, 2016 , respectively. If recognized, $2.4 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.

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. 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, 2017 and December 31, 2016 , 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 , 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. 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.

Note 15. Business Segment Information

We supply products and services primarily to the aerospace and defense industries. Our subsidiaries are organized into two strategic businesses, Structural Systems and Electronic Systems, each of which is a reportable operating segment.

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.

Third quarter 2017 highlights:


•	Revenues of $138.7 million


•	Net income of $4.7 million , or $0.41 per diluted share


•	Adjusted EBITDA of $14.5 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 charges (“Adjusted EBITDA”) was $14.5 million and $14.9 million for the three months ended September 30, 2017 and October 1, 2016 , 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 substitutes 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

Table of Contents


•	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;


•	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.

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

Net revenues for the three months ended September 30, 2017 were $138.7 million, compared to $132.6 million for the three months ended October 1, 2016 . The year-over-year increase was primarily due to the following:


•	$8.1 million higher revenues in our military and space end-use markets mainly due to increased demand, which favorably impacted our fixed-wing, missile, and helicopter platforms; and


•	$0.9 million higher revenues in our industrial end-use markets; partially offset by


•	$2.8 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.

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.

	September 30, 2017		December 31, 2016
Boeing	15.4	%	7.8	%
Lockheed Martin	4.8	%	2.9	%
Raytheon	6.2	%	10.9	%
Spirit	10.9	%	9.0	%
United Technologies	3.0	%	7.8	%

The net revenues and accounts receivable from Boeing, Lockheed Martin, Raytheon, Spirit, and United Technologies are diversified over a number of commercial, military and space programs and were generated by both operating segments.

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 decreased year-over-year in the three months ended September 30, 2017 to 18.8% compared to the three months ended October 1, 2016 of 19.0% primarily due to unfavorable product mix, partially offset by lower manufacturing costs as a result of ongoing cost reduction initiatives.

Gross profit margin as a percentage of net revenues decreased year-over-year in the nine months ended September 30, 2017 to 18.5% compared to the nine months ended October 1, 2016 of 19.2% primarily due to unfavorable product mix, partially offset by lower manufacturing costs as a result of ongoing cost reduction initiatives and higher manufacturing volume.

Selling, General and Administrative (“SG&A”) Expenses

SG&A expenses increased $1.6 million year-over-year in the three months ended September 30, 2017 compared to the three months ended October 1, 2016 primarily due to higher compensation and benefit costs 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 divestitures of our Pittsburgh and Miltec operations and closure of certain facilities of $1.3 million.

Interest Expense

Interest expense increased year-over-year in the three months ended September 30, 2017 compared to the three months ended October 1, 2016 primarily due to a higher utilization of 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 as a result of voluntary principal prepayments 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).

Income Tax Expense

We recorded income tax expense of $0.9 million (effective tax rate of 16.8% ) for the three months ended September 30, 2017 compared to $1.2 million (effective tax rate of 19.8% ) for the three months ended October 1, 2016 . The decrease in the effective tax rate for the three months ended September 30, 2017 compared to the three months ended October 1, 2016 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 the 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 rate 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, 2017 compared to the nine months ended October 1, 2016 was primarily due to the preliminary gain on divestitures of 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.

Our total amount of unrecognized tax benefits was $3.7 million and $3.0 million as of September 30, 2017 and December 31, 2016, respectively. If recognized, $2.4 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 30, 2017 were $4.7 million , or $0.41 per diluted share, compared to $5.0 million , or $0.44 per diluted share, for the three months ended October 1, 2016 . The decrease in net income for the three months ended September 30, 2017 compared to the three months ended October 1, 2016 was primarily due to the following:


•	$1.6 million higher SG&A expense; partially offset by


•	$0.3 million of lower income tax expense.

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:


•	The prior year included a preliminary pre-tax gain on divestitures of our Pittsburgh and Miltec operations of $18.8 million; partially offset by


•	$7.8 million lower income tax expense.

Business Segment Performance

We report our financial performance based upon the two reportable operating segments: Structural Systems and Electronic 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 30, 2017 and October 1, 2016 :

Structural Systems

Structural Systems’ net revenues in the three months ended September 30, 2017 compared to the three months ended October 1, 2016 decreased $1.2 million 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


•	$0.3 million higher revenues in our military and space end-use markets mainly due to increased demand, which favorably impacted our helicopter platforms.

Structural Systems’ net revenues in the nine months ended September 30, 2017 compared to the nine months ended October 1, 2016 decreased $9.3 million primarily due to the following:

Table of Contents


•	$13.7 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


•	$4.4 million higher revenues in our military and space end-use markets mainly due to increased demand, which favorably impacted our helicopter platforms.

The Structural Systems segment operating income in the three and nine months ended September 30, 2017 compared to the three and nine months ended October 1, 2016 decreased $2.4 million and $5.2 million, respectively, primarily due to the impact of new program development on large airframe platforms and lower manufacturing volume.

Electronic Systems

Electronic Systems’ net revenues in the three months ended September 30, 2017 compared to the three months ended October 1, 2016 increased $7.4 million primarily due to the following:


•	$7.7 million higher revenues in our military and space end-use markets mainly due to increased demand, which favorably impacted our fixed-wing, missile, and helicopter platforms; and


•	$0.9 million higher revenues in our Industrial end-use markets; partially offset by


•	$1.3 million lower revenues in our commercial aerospace end-use markets mainly due to continued softness in demand in the business jet market.

Electronic Systems’ net revenues in the nine months ended September 30, 2017 compared to the nine months ended October 1, 2016 increased $17.0 million primarily due to the following:


•	$27.5 million higher revenues in our military and space end-use markets mainly due to increased demand, which favorably impacted our fixed-wing, helicopter, and missile platforms, partially offset by the divestiture of our Miltec operation in March 2016. The net increase was partially offset by


•	$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; and


•	$3.1 million lower revenues in our commercial aerospace end-use markets mainly due to continued softness in demand in the business jet market.

Electronic Systems’ segment operating income in the three and nine months ended September 30, 2017 compared to the three and nine months ended October 1, 2016 increased $1.6 million and $4.4 million, respectively, primarily due to higher manufacturing volume and lower manufacturing costs as a result of ongoing cost reduction initiatives, partially offset by unfavorable product mix.

Corporate General and Administrative (“CG&A”) Expenses

CG&A expenses increased $0.1 million in the three months ended September 30, 2017 compared to the three months ended October 1, 2016 .

CG&A expenses increased $1.0 million 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 $2.5 million, partially offset by lower professional services fees of $1.3 million.

Backlog

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-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 million of total backlog is expected to be delivered over the next 12 months. The following table summarizes our backlog as of September 30, 2017 and December 31, 2016 :

Liquidity and Capital Resources

Available Liquidity

Total debt, the weighted-average interest rate, cash and cash equivalents and available credit facilities were as follows:



	(In millions)
	September 30,			December 31,

Term Loan interest rate	3.44		%	3.31		%
Cash and cash equivalents	$	3.7		$	7.4
Unused Revolving Credit Facility	$	134.5		$	199.0

Our credit facility consists of a $275.0 million senior secured term loan, which matures on June 26, 2020 (“Term Loan”), and a $200.0 million senior secured revolving credit facility (“Revolving Credit Facility”), which matures on June 26, 2020 (collectively, the “Credit Facilities”). We are required to make mandatory prepayments of amounts outstanding under the Term Loan. As of September 30, 2017, we were in compliance with all covenants required under the Credit Facilities. See Note 9 to our condensed consolidated financial statements included in Part I, Item 1 of this Form 10-Q for further information. On July 14, 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.

On September 11, 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 2 for further information.

We expect to spend a total of $26.0 million to $30.0 million for capital expenditures in 2017 financed by cash generated from operations, principally to support the expansion of our Parsons, Kansas facility and new contract awards at Structural Systems

Table of Contents

and Electronic Systems. As part of our strategic plan to become a Tier 2 supplier 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 Credit Facilities to provide short-term liquidity. Cash generated from operations and bank borrowing capacity is expected to provide sufficient liquidity to meet our obligations during the next twelve months.

Cash Flow Summary

Net cash provided by operating activities for the nine months ended September 30, 2017 decreased to $27.4 million , compared to $27.6 million for the nine months ended October 1, 2016 . The lower net cash generated during the first nine months of 2017 was primarily due to lower net income, partially offset by higher accounts payable mainly due to the timing of payments.

Net cash used in investing activities of $83.5 million for the nine months ended September 30, 2017 compared to net cash provided by of $42.6 million in the nine months ended October 1, 2016 primarily due to the payments for the purchase of LDS, net of cash acquired of $59.2 million in the current year nine month period compared to the prior year nine month period which included proceeds from the divestiture of our Pittsburgh and Miltec operations of approximately $55.3 million and purchases of property and equipment mainly to support the expansion of our Parsons, Kansas facility.

Net cash provided by financing activities for the nine months ended September 30, 2017 of $52.4 million was primarily due to net borrowings from the Revolving Credit Facility that was used for the purchase of LDS, partially offset by repayments on the Credit Facilities.

Off-Balance Sheet Arrangements

Our off-balance sheet arrangements consist of operating leases 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 2016 Annual Report on Form 10-K. There have been no material changes in any of our critical accounting policies during the three and nine months ended September 30, 2017 .

Recent Accounting Pronouncements

See “Part I, Item 1. Ducommun Incorporated and Subsidiaries—Notes to Condensed Consolidated Financial Statements—Note 1. Summary of Significant Accounting Policies—Recent Accounting Pronouncements” for further information.

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 , we had total borrowings of $224.7 million under our Term Loan and Revolving Credit Facility that bear 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 2.75% 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% to 1.75% 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

Table of Contents

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’s disclosure controls and procedures were not effective as of September 30, 2017 .

Management’s Remediation Activities

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 consist 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.

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 controls over financial reporting during the three months ended September 30, 2017 that have materially affected, or are reasonably likely to materially affect, our internal controls over financial reporting.
