Note 1. Summary of Significant Accounting Policies

Basis of Presentation

The 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, 2012 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 II, Item 8. “Note 1. Summary of Significant Accounting Policies” in our Annual Report on Form 10-K for the year ended December 31, 2012. We follow the same accounting policies for interim reporting, with the exception of accounting principles adopted as of January 1, 2013, as discussed below in Recent Accounting Pronouncements. The financial information included in this Quarterly Report on Form 10-Q should be read in conjunction with our consolidated financial statements and related notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2012.

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 six months ended June 29, 2013 are not necessarily indicative of the results to be expected for the full year ending December 31, 2013.

Certain prior year reclassifications have been made to conform to the current year financial statement presentation.

Use of Estimates

Certain amounts and disclosures included in the condensed consolidated financial statements required management to make estimates and judgments that affect the amounts of assets, liabilities, 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.

Description of Business

We are a global provider of engineering and manufacturing products and services primarily to the aerospace and defense industry through a wide range of products and services in the primary businesses of electronics, structures and integrated solutions. Our subsidiaries are organized into two strategic businesses, each of which is a reportable operating segment. Ducommun AeroStructures (“DAS”) designs, engineers and manufactures large, complex contoured aerospace structural components and assemblies and supplies composite and metal bonded structures and assemblies. Ducommun LaBarge Technologies (“DLT”) designs, engineers and manufactures high-reliability products used in worldwide technology-driven markets including aerospace and defense, natural resources, industrial and medical and other end-use markets. DLT’s product offerings range from prototype development to complex assemblies. Each reportable operating segment follows the same accounting principles.

Accumulated Other Comprehensive Loss

Accumulated other comprehensive loss, as reflected on the condensed consolidated balance sheets, was composed of cumulative pension and liability adjustments of $7.1 million and $7.5 million, net of tax, at June 29, 2013 and December 31, 2012, respectively.

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 the sum of income available to common shareholders plus income associated with dilutive securities 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 earnings and 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.

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 below.

Out of Period Adjustment

During the first quarter of 2012, we determined that approximately $0.4 million of engineering research and development costs had been capitalized in error in inventory in prior periods. We assessed the materiality of this error and concluded it was immaterial to currently reported annual and previously reported annual and interim amounts. We corrected the error in the first quarter of 2012 and did not restate our consolidated financial statements for the prior annual or interim periods.

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.

Recent Accounting Pronouncements

New Accounting Guidance Adopted in 2013

In February 2013, the Financial Accounting Standards Board (the “FASB”) issued guidance to improve the reporting of reclassifications out of accumulated other comprehensive income/loss. The new guidance requires an entity to report the effect of significant reclassifications out of accumulated other comprehensive income/loss on the respective line items in net income if the amount being reclassified is required under GAAP to be reclassified in its entirety to net income. For other amounts that are not required under GAAP to be reclassified in their entirety to net income in the same reporting period, cross-reference to other disclosures that provide additional detail is required. Early adoption is permitted. We adopted this new guidance effective January 1, 2013. This guidance affects disclosures only.

In January 2013, the FASB issued guidance clarifying the scope of disclosures about offsetting assets and liabilities and requires retrospective application for all periods presented. We adopted this new guidance effective January 1, 2013. The adoption of this new guidance did not have any effect on our condensed consolidated financial statements. In December 2011, the FASB issued guidance enhancing disclosure requirements about the nature of an entity’s right to offset and related arrangements associated with its financial instruments and derivative instruments. The new guidance requires the disclosure of the gross amounts subject to rights of set-off, amounts offset in accordance with the accounting standards followed, and the related net exposure. The new guidance requires retrospective application for all comparable periods presented. We adopted this new guidance effective January 1, 2013. The adoption of this new guidance did not have any effect on our condensed consolidated financial statements.

New Accounting Guidance Not Yet Adopted

In February 2013, the FASB issued guidance for the recognition, measurement and disclosure of obligations resulting from joint and several liability arrangements for which the total amount of the obligation is fixed at the reporting date, except for obligations addressed within existing guidance in GAAP. The new guidance will be effective for us beginning January 1, 2014. Early adoption is permitted. We do not expect the adoption of this guidance to have a material effect on our condensed consolidated financial statements.

Note 2. Inventories

Inventories consisted of the following:

Note 3. Goodwill

Goodwill was as follows:

Note 4. Long-Term Debt

Long-term debt was as follows:

On March 28 and April 30, 2013, we made voluntary principal prepayments of $7.5 million each on our senior secured term loan.

On March 28, 2013, we completed a repricing of our senior secured term loan and revolving credit facility (the “Credit Facilities”). The repricing reduced the interest rate spread on the Credit Facilities by 50 basis points and the interest rate floor by 25 basis points. In connection with this repricing, we recognized $0.5 million of financing and legal costs which were included in selling, general and administrative expenses in the first quarter of 2013.

At June 29, 2013, we had $58.4 million of unused borrowing capacity under the revolving credit facility, after deducting $1.6 million for standby letters of credit.

At June 29, 2013, we were in compliance with all covenants required by the Credit Facilities’ credit agreement. At June 29, 2013, there were no amounts outstanding that would have triggered the leverage covenant under the Credit Facilities’ credit agreement. However, we would have been in compliance with such leverage covenant.

The carrying amount of long-term debt approximates fair value, except for the senior unsecured notes for which the fair value was $219.5 million. Fair value was estimated using Level 2 inputs, based on the terms of the related debt, recent transactions and estimates using interest rates currently available to us for debt with similar terms and remaining maturities.

Note 5. Shareholders’ Equity

We are authorized to issue five million shares of preferred stock. At June 29, 2013 and December 31, 2012, no preferred shares were issued or outstanding.

Note 6. Employee Benefit Plans

The components of net periodic pension expense were as follows:

The components of the reclassifications from accumulated other comprehensive loss to net income during the three and six months ended June 29, 2013 were as follows:

Note 7. Indemnification

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 varies and, in many cases, is indefinite but subject to statute 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 in the accompanying condensed consolidated balance sheets.

Note 8. Income Taxes

The effective tax rates were 27.6% and 8.6%, respectively, for the three and six months ended June 29, 2013, and were 4.7% and 16.0%, respectively, for the comparable periods of 2012.

The effective tax rate in the six months ended June 29, 2013 included $2.0 million of 2012 federal research and development tax credit benefits recognized in the first quarter of 2013 as a result of the American Taxpayer Relief Act of 2012, passed in January 2013. This Act includes an extension of the federal research and development tax credit for the amounts paid or incurred after December 31, 2011 and before January 1, 2014. We recognized total federal research and development tax credit benefits of $2.5 million and $0.5 million in the first quarter and second quarter of 2013, respectively. We expect to continue to recognize approximately $0.5 million per quarter for these benefits throughout 2013. The effective tax rate for the three and six months ended June 30, 2012 included no federal research and development tax credit benefits. The effective tax rate for the three and six months ended June 30, 2012 included a benefit of $1.6 million as a result of the 2011 acquisition of LaBarge Inc., which allowed us to file state consolidated tax returns in certain states.

Our unrecognized tax benefits were $2.2 million and $1.7 million at June 29, 2013 and December 31, 2012, respectively. Most of these amounts, if recognized, would affect our annual income tax rate.

Note 9. Contingencies

Ducommun is a defendant in a lawsuit entitled United States of America ex rel Taylor Smith, Jeannine Prewitt and James Ailes v. The Boeing Company and Ducommun Inc., filed in the United States District Court for the District of Kansas (the “District Court”). The lawsuit is a qui tam action brought by three former Boeing employees (“Relators”) against Boeing and Ducommun on behalf of the United States of America for violations of the United States False Claims Act. The lawsuit alleges that Ducommun sold unapproved parts to the Boeing Company (“Boeing”), which were installed by Boeing in aircraft ultimately sold to the United States Government and that Boeing and Ducommun submitted or caused to be submitted false claims for payment relating to 21 aircraft sold by Boeing to the United States Government. The lawsuit seeks damages in an amount equal to three times the amount of damages the United States Government sustained because of the defendants’ actions, plus a civil penalty of $10 thousand for each false claim made on or before September 28, 1999, and $11 thousand for each false claim made on or after September 28, 1999, together with attorneys’ fees and costs. The Relators claim that the United States Government sustained damages of $1.6 billion (the contract purchase price of 21 aircraft) or, alternatively, $851 million (the alleged diminished value and increased maintenance cost of the 21 aircraft). After investigating the allegations, the United States Government has declined to intervene in the lawsuit. Ducommun and Boeing have filed motions for summary judgment to dismiss the lawsuit. The motions for summary judgment are pending before the District Court. Ducommun intends to defend itself vigorously against the lawsuit. Ducommun, at this time, is unable to estimate what, if any, liability it may have in connection with the lawsuit.

DAS 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 a reserve for its estimated liability for such investigation and corrective action of approximately $1.5 million at June 29, 2013, which is reflected in other long-term liabilities on its condensed consolidated balance sheet.

DAS also faces liability as a potentially responsible party for hazardous waste disposed at landfills located in Casmalia and West Covina, California. DAS 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, is between approximately $0.4 million and $3.1 million. Ducommun has established a reserve for its estimated liability, in connection with the West Covina landfill of approximately $0.4 million at June 29, 2013, 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 consolidated financial position, results of operations or cash flows.

Note 10. Business Segment Information

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