Item 1.  Business

General Development of Business

Esterline, a Delaware corporation formed in 1967, is a leading specialized manufacturing company principally serving aerospace and defense customers. We design, manufacture and market highly engineered products and systems for application within the industries we serve.

Our strategy is to maintain a leadership position in niche markets for the development and manufacture of highly engineered products that are essential to our customers. We are concentrating our efforts to expand selectively our capabilities in these markets, to anticipate the global needs of our customers and to respond to such needs with comprehensive solutions. Our current business and strategic growth plan focuses on the continuous development of these products in three key technology segments: Avionics & Controls, Sensors & Systems, and Advanced Materials. Our products are often mission critical, which have been designed into particular military and commercial platforms and in certain cases can only be replaced by products of other manufacturers following a formal certification process. As part of our implementation of this growth plan, we focus on expansion of our capabilities as a more comprehensive supplier to our customers. Such expansion included the February 4, 2013, acquisition of the Gamesman Group (Gamesman), which is a global supplier of input devices principally serving the gaming industry; the July 26, 2011, acquisition of the Souriau Group (Souriau), which is a leading global supplier of highly engineered connection technologies for harsh environments; and the December 30, 2010, acquisition of Eclipse Electronic Systems, Inc. (Eclipse), which develops and manufactures embedded communication intercept receivers for signal intelligence applications. These acquisitions are described in more detail in the “Overview” section of Management’s Discussion and Analysis of Financial Condition and Results of Continuing Operations contained in Item 7 of this report.

Our products have a long history in the aerospace and defense industry and are found on most military and commercial aircraft, helicopters, and land-based systems. For example, our products are used on the majority of active and in-production U.S. military aircraft and on every Boeing commercial aircraft platform manufactured in the past 75 years. In addition, our products are supplied to Airbus, many of the major regional and business jet manufacturers, and the major aircraft engine manufacturers. We work closely with OEMs on new, highly engineered products with the objective of such products becoming designed into our customers’ platforms; this integration often results in sole-source positions for OEM production and aftermarket business. We broadly categorize our commercial and military aerospace aftermarket sales as retrofit, repair services, and spare parts. Spare parts alone made up approximately 10% of total sales in fiscal 2013. Retrofit and repair services, which represent 5% of total sales, carry higher margins than OEM sales, but lower margins than spare parts sales. In many cases, our aftermarket sales span the entire life of an aircraft.

We differentiate ourselves through our engineering and manufacturing capabilities and our reputation for safety, quality, on-time delivery, reliability, and innovation – all embodied in the Esterline Performance System, our way of approaching business that helps ensure all employees are focused on continuous improvement. Safety of our operations is a critical factor in our business, and accordingly, we incorporate applicable regulatory guidance in the design of our facilities and train our employees using a behavior-based approach that focuses on safety-designed work habits and on-going safety audits. Our industries are highly regulated, and compliance with applicable regulations, including export control and anti-bribery regulations, is an important focus in our business. For example, we have a global code of business conduct and ethics that covers compliance with laws, and we provided training on this code to our worldwide employees in fiscal 2013. In addition, we maintain local ethics advisors and export control specialists in our business units to support our compliance efforts.

Our sales are diversified across three broad markets: defense, commercial aerospace, and general industrial. For fiscal 2013, approximately 35% of our sales were from the defense market, 45% from the commercial aerospace market, and 20% from the general industrial market.

A summary of product lines contributing sales of 10% or more of total sales for fiscal years 2013, 2012, and 2011 is reported in Note 16 to the Consolidated Financial Statements under Item 8 of this report.

Marketing and Distribution

We believe that a key to continued success is our ability to meet customer requirements both domestically and internationally. We have and will continue to improve our world-wide sales and distribution channels in order to provide wider market coverage and to improve the effectiveness of our customers’ supply chain. For example, our medical device assembly operation in Shanghai, China, serves our global medical customers, our service center in Singapore improves our capabilities in Asia for our temperature sensor customers, our marketing representative office in Bangalore, India, facilitates marketing opportunities in India, and our marketing representative office in Beijing, China, facilitates marketing opportunities in China. Other enhancements include combining sales and marketing forces of our operating units where appropriate, cross-training our sales representatives on multiple product lines, and cross-stocking our spares and components.

In the technical and highly engineered product segments in which we compete, relationship selling is particularly appropriate in targeted marketing segments where customer and supplier design and engineering inputs need to be tightly integrated. Participation in industry trade shows is an effective method of meeting customers, introducing new products, and exchanging technical specifications. In addition to technical and industry conferences, our products are supported through direct internal international sales efforts, as well as through manufacturer representatives and selected distributors. As of October 25, 2013, 398 sales people, 324 representatives, and 340 distributors supported our operations internationally.

Backlog

Backlog was $1.3 billion at October 25, 2013, and October 26, 2012. We estimate that approximately $332 million of backlog is scheduled to be shipped after fiscal 2014.

Backlog is subject to cancellation until delivered, and therefore, we cannot assure that our backlog will be converted into revenue in any particular period or at all. Backlog does not include the total contract value of cost-plus reimbursable contracts, which are funded as we incur the costs. Except for the released portion, backlog also does not include fixed-price multi-year contracts.

Competition

Our products and services are affected by varying degrees of competition. We compete with other companies in most markets we serve. Many of these companies have far greater sales volumes and financial resources than we do. Some of our competitors are also our customers on certain programs. The principal competitive factors in the commercial markets in which we participate are product performance, on-time delivery, service and price. Part of product performance requires expenditures in research and development that lead to product improvement. The market for many of our products may be affected by rapid and significant technological changes and new product introductions. Our principal competitors include Astronautics, BAE, Bose, Eaton, Elbit, EMS, GE Aerospace, Honeywell, IAI, L-3, Otto Controls, RAFI, Rockwell Collins, SELEX, Telephonics, Thales, Ultra Electronics, Universal Avionics Systems Corporation, and Zodiac in our Avionics & Controls segment; Ametek, Amphenol, Eaton, Goodrich, Hamilton Sundstrand, Meggitt, STPI-Deutsch, TE Connectivity, and Zodiac in our Sensors & Systems segment; and Chemring, Doncasters, Hi-Temp, J&M, JPR Hutchinson, Kmass, Meggitt (including Dunlop Standard Aerospace Group), Rheinmetall, Trelleborg, ULVA, UMPCO, and Woodward Products in our Advanced Materials segment.

Research and Development

Our product development and design programs utilize an extensive base of professional engineers, technicians and support personnel, supplemented by outside engineering and consulting firms when needed. In fiscal 2013, we expended $95.7 million for research, development and engineering, compared with $107.7 million in fiscal 2012 and $94.5 million in fiscal 2011. Research and development expense has averaged 5.2% of sales for the three years ended October 25, 2013. We believe continued product development is key to our long-term growth, and consequently, we consistently invest in research and development. Examples include research and development projects relating to avionics control panels, A350

6

engine sensors, high temperature, low observable material for military applications, and spectral countermeasure flares for military applications. We actively participate in customer-funded research and development programs, including applications on C-130 cockpit upgrades, P-8 aircraft and power systems for the HH-47 Chinook helicopter and A400M.

Foreign Operations

Our foreign operations consist of manufacturing facilities located in Canada, China, the Dominican Republic, France, Germany, India, Japan, Mexico, Morocco, and the United Kingdom, and include sales and service operations located in Brazil, China, and Singapore. For further information regarding foreign operations, see Note 16 to the Consolidated Financial Statements under Item 8 of this report.

U.S. Government Contracts and Subcontracts

As a contractor and subcontractor to the U.S. government (primarily the U.S. Department of Defense), we are subject to various laws and regulations that are more restrictive than those applicable to private sector contractors. Approximately 6% of our sales was made directly to the U.S. government in fiscal 2013. In addition, we estimate that our subcontracting activities to contractors for the U.S. government accounted for approximately 17% of sales during fiscal 2013. In total, we estimate that approximately 23% of our sales during the fiscal year was subject to U.S. government contracting regulations. Such contracts may be subject to termination, reduction or modification in the event of changes in government requirements, reductions in federal spending, and other factors.

Historically, our U.S. government contracts and subcontracts have been predominately fixed-price contracts. Generally, fixed-price contracts offer higher margins than cost-plus contracts in return for accepting the risk that increased or unexpected costs may reduce anticipated profits or cause us to sustain losses on the contracts. The accuracy and appropriateness of certain costs and expenses used to substantiate our direct and indirect costs for the U.S. government under both cost-plus and fixed-price contracts are subject to extensive regulation and audit by the Defense Contract Audit Agency, an arm of the U.S. Department of Defense. The contracts and subcontracts to which we are a party are also subject to profit and cost controls and standard provisions for termination at the convenience of the U.S. government. Upon termination, other than for our default, we will normally be entitled to reimbursement for allowable costs and to an allowance for profit. To date, none of our material fixed-price contracts have been terminated.

We are subject to U.S. export laws and regulations, including the International Traffic in Arms Regulations (ITAR), that generally restrict the export of defense products, technical data, and defense services. We recorded a $10 million charge as of July 26, 2013, for penalties proposed by the DDTC Office of Compliance associated with our earlier handling of ITAR-controlled transactions and related compliance errors, as described further in this report under “Item 3 – Legal Proceedings.” Our failure to comply with applicable regulations could result in penalties, loss, or suspension of contracts or other consequences, and the costs to maintain compliance with these regulations may be higher than we anticipate. Any of these consequences could adversely affect our operations or financial condition.

Patents and Licenses

Although we hold a number of patents and licenses, we do not believe that our operations are dependent on our patents and licenses. In general, we rely on technical superiority, continual product improvement, exclusive product features, lean manufacturing and operational excellence, including superior lead-time, on-time delivery performance and quality, and customer relationships to maintain competitive advantage.

Seasonality

The timing of our revenues is impacted by the purchasing patterns of our customers, and as a result we do not generate revenues evenly throughout the year. Moreover, our first fiscal quarter, November through January, includes significant holiday vacation periods in both Europe and North America. This leads to decreased order and shipment activity; consequently, first quarter results are typically weaker than other quarters and not necessarily indicative of our performance in subsequent quarters.

Sources and Availability of Raw Materials and Components

The sources and availability of certain raw materials and components are not as critical as they would be for manufacturers of a single product line, due to our vertical integration and diversification. However, certain components, supplies and raw materials for our operations are purchased from single sources. In such instances, we strive to develop alternative sources and design modifications to minimize the effect of business interruptions.

7

Environmental Matters

We are subject to federal, state, local and foreign laws, regulations and ordinances that (i) govern activities or operations that may have adverse environmental effects, such as discharges to air and water, as well as handling and disposal practices for solid and hazardous waste, and (ii) impose liability for the costs of cleaning up, and certain damages resulting from, sites or past spills, disposals or other releases of hazardous substances.

At various times we have been identified as a potentially responsible party pursuant to the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA), and analogous state environmental laws, for the cleanup of contamination resulting from past disposals of hazardous wastes at certain sites to which we, among others, sent wastes in the past. CERCLA requires potentially responsible persons to pay for cleanup of sites from which there has been a release or threatened release of hazardous substances. Courts have interpreted CERCLA to impose strict, joint and several liability on all persons liable for cleanup costs. As a practical matter, however, at sites where there are multiple potentially responsible persons, the costs of cleanup typically are allocated among the parties according to a volumetric or other standard.

We have accrued liabilities for environmental remediation costs expected to be incurred. Environmental exposures are provided for at the time they are known to exist or are considered reasonably probable and estimable.

Employees

We had 12,049 employees at October 25, 2013, of which 4,982 were based in the United States, 4,174 in Europe, 1,026 in Canada, 632 in Mexico, 584 in Asia, 516 in Morocco and 135 in the Dominican Republic. Approximately 12% of the U.S.-based employees were represented by a labor union. Our European operations are subject to national trade union agreements and to local regulations governing employment.

Item 1A.  Risk Factors

Risks Relating to Our Business and Our Industry

Reductions in defense spending could adversely affect our business.

Approximately 35% of our business is dependent on defense spending. The defense industry is dependent upon the level of equipment expenditures by the armed forces of countries throughout the world, and especially those of the United States, which represents a significant portion of world-wide defense expenditures. In August 2011, Congress enacted the Budget Control Act of 2011 (BCA), which resulted in substantial, automatic reductions in both defense and discretionary spending. The automatic across-the-board budget cuts, or sequestration, are incremental to spending reductions already included in the defense funding over a ten-year period. These spending cuts impacted our financial results in fiscal 2013, and could have significant future consequences to our business and industry, including disruption of programs and personnel reductions that could impact our manufacturing operations and engineering capabilities.

The loss of a significant customer or defense program could have a material adverse effect on our operating results.

Some of our operations are dependent on a relatively small number of customers and aerospace and defense programs, which change from time to time. Significant customers in fiscal 2013 included The Boeing Company, Flame, General Electric, Hawker Beechcraft, Honeywell, Lockheed Martin, Northrop Grumman, Rolls-Royce, Sikorsky, and the U.S. Department of Defense. There can be no assurance that our current significant customers will continue to buy our products at current levels. The loss of a significant customer or the cancellation of orders related to a sole-source defense program could have a material adverse effect on our operating results if we were unable to replace the related sales.

We are subject to numerous regulatory requirements, which could adversely affect our business.

Among other things, we are subject to the Foreign Corrupt Practices Act, or FCPA, and the U.K. Bribery Act, which generally prohibit companies and their intermediaries from bribing foreign officials for the purpose of obtaining or keeping business or otherwise obtaining favorable treatment. In particular, we may be held liable for actions taken by our strategic or local partners even though our partners are not subject to the FCPA or the U.K. Bribery Act. Any determination that we have violated the FCPA or the U.K. Bribery Act could result in sanctions that could have a material adverse effect on our business, financial condition and results of operations.

10

We are also subject to a variety of international laws, as well as U.S. export laws and regulations, such as the International Traffic in Arms Regulations (ITAR), which generally restrict the export of defense products, technical data and defense services. We have filed voluntary reports that disclosed certain technical and administrative violations of the ITAR with the U.S. Department of State’s Directorate of Defense Trade Controls (DDTC) Office of Defense Trade Controls Compliance (DDTC Office of Compliance). As further described in this report under “Item 3 – Legal Proceedings,” we recorded a $10 million charge as of July 26, 2013, for penalties proposed by the DDTC Office of Compliance associated with our earlier handling of ITAR-controlled transactions, including the substance of our prior voluntary disclosures and other aspects of ITAR compliance errors. Our failure to comply with these regulations could result in penalties, loss, or suspension of contracts or other consequences. Any of these could adversely affect our operations and financial condition.

We may be unable to realize expected benefits from our business integration efforts and our profitability may be hurt or our business otherwise might be adversely affected.

We recently announced that we are accelerating plans to consolidate certain facilities and to create greater cost efficiencies through shared services in sales, general administration and support functions across our segments. We have never before pursued integration initiatives to this extent, and there is no assurance that our efforts will be successful. These plans are intended to generate operating expense savings through direct and indirect overhead expense reductions as well as other savings. These integration activities are complex. If we do not successfully manage our current integration activities, or any other similar activities that we may undertake in the future, expected efficiencies and benefits might be delayed or not realized, and our operations and business could be disrupted. Risks associated with these actions include inability to or delay in the planned transfer of business activities to other locations due to dependency on third party agreements or certification of projects affected by the transfer, unanticipated costs in implementing the initiatives, delays in implementation of anticipated workforce reductions, adverse effects on employee morale, creation of customer or supplier uncertainty that may impact our business and the failure to meet operational targets due to the loss of employees. If any of these risks are realized, our ability to achieve anticipated cost reductions may be impaired or our business may otherwise be harmed, which could have a material adverse effect on our competitive position, results of operations, cash flows or financial condition.

Implementing our acquisition strategy involves risks, and our failure to successfully implement this strategy could have a material adverse effect on our business.

One of our key strategies is to grow our business by selectively pursuing acquisitions. Since 1996 we have completed over 30 acquisitions, and we are continuing to actively pursue additional acquisition opportunities, some of which may be material to our business and financial performance. Although we have been successful with this strategy in the past, we may not be able to grow our business in the future through acquisitions for a number of reasons, including:

In addition, there are potential risks associated with growing our business through acquisitions, including the failure to successfully integrate and realize the expected benefits of an acquisition. For example, with any past or future acquisition, there is the possibility that:

Failure to continue implementing our acquisition strategy, including successfully integrating acquired businesses, could have a material adverse effect on our business, financial condition and results of operations.

11

Our future financial results could be adversely impacted by asset impairment charges.

We are required to test both acquired goodwill and other indefinite-lived intangible assets for impairment on an annual basis based upon a fair value approach, rather than amortizing them over time. We have chosen to perform our annual impairment reviews of goodwill and other indefinite-lived intangible assets during the fourth quarter of each fiscal year. We also are required to test goodwill for impairment between annual tests if events occur or circumstances change that would more likely than not reduce our enterprise fair value below its book value. These events or circumstances could include a significant change in the business climate, including a significant sustained decline in an entity’s market value, legal factors, operating performance indicators, competition, sale or disposition of a significant portion of the business, or other factors. If the fair market value is less than the book value of goodwill, we could be required to record an impairment charge. The valuation of reporting units requires judgment in estimating future cash flows, discount rates and estimated product life cycles. In making these judgments, we evaluate the financial health of the business, including such factors as industry performance, changes in technology and operating cash flows.

As we have grown through acquisitions, we have accumulated $1.1 billion of goodwill, and have $47.2 million of indefinite-lived intangible assets, out of total assets of $3.3 billion at October 25, 2013. As a result, the amount of any annual or interim impairment could be significant and could have a material adverse effect on our reported financial results for the period in which the charge is taken. For example, we recorded an impairment charge of $3.5 million in fiscal 2013, and an impairment charge of $52.2 million in fiscal 2012 at Racal Acoustics, Inc. (Racal Acoustics). In addition, we may incur additional charges.

We performed our annual impairment review for fiscal 2013 as of July 27, 2013, and our Step One analysis indicates that no impairment of goodwill or other indefinite-lived assets exists at any of our other reporting units. Our Souriau reporting unit’s margin in passing the Step One analysis was approximately 12%, mainly reflecting lower market valuation assumptions in 2013. Management expects that continued improvements in operations will result in favorable actual results compared with our original plan. It is possible, however, that as a result of events or circumstances, we could conclude at a later date that goodwill of $347.6 million at Souriau may be considered impaired. We also may be required to record an earnings charge or incur unanticipated expenses if, due to a change in strategy or other reasons, we determined the value of other assets has been impaired. These other assets include trade names of $33.7 million and intangible assets of $181.7 million.

A long-lived asset to be disposed of is reported at the lower of its carrying amount or fair value less cost to sell. An asset (other than goodwill and indefinite-lived intangible assets) is considered impaired when estimated future undiscounted cash flows are less than the carrying amount of the asset. In the event the carrying amount of such asset is not deemed recoverable, the asset is adjusted to its estimated fair value. Fair value is generally determined based upon estimated discounted future cash flows. As we have grown through acquisitions, we have accumulated $533.8 million of definite-lived intangible assets. As a result, the amount of any annual or interim impairment could be significant and could have a material adverse effect on our reported financial results for the period in which the charge is taken.

The amount of debt we have outstanding, as well as any debt we may incur in the future, could have an adverse effect on our operational and financial flexibility.

As of October 25, 2013, we had approximately $689.1 million of long-term debt outstanding. Under our existing secured credit facility, we have a $460 million revolving line of credit, an €18.0 million term loan (Euro Term Loan), and a $170.6 million term loan (U.S. Term Loan). The credit facility is secured by substantially all of the Company’s assets and interest is based on standard inter-bank offering rates. In addition, we have unsecured foreign currency credit facilities that have been extended by foreign banks for up to $66.2 million. Available credit under the above credit facilities was $363.5 million at October 25, 2013, reflecting bank borrowings of $130.0 million and letters of credit of $32.7 million.

We also have outstanding $250.0 million 7.0% Senior Notes due in August 2020 (2020 Notes). The indentures governing those notes and other debt agreements limit, but do not prohibit, us from incurring additional debt in the future. Our level of debt could have significant consequences to our business, including the following:

12

Our revenues are subject to fluctuations that may cause our operating results to decline.

Our business is susceptible to seasonality and economic cycles, and as a result, our operating results have fluctuated widely in the past and are likely to continue to do so. Our revenue tends to fluctuate based on a number of factors, including domestic and foreign economic conditions and developments affecting the specific industries and customers we serve. For example, it is possible that a global recession could occur and result in a more severe downturn in commercial aviation and defense.

It is also possible that in the future our operating results in a particular quarter or quarters will not meet the expectations of securities analysts or investors, causing the market price of our common stock or senior notes to decline. We believe that quarter-to-quarter comparisons of our operating results are not a good indication of our future performance and should not be relied upon to predict our future performance.

A global recession may adversely affect our business operations and results, capital, and cost of capital.

In the event of a global recession, our customers may choose to delay or postpone purchases from us until the economy and their business strengthen. Decisions by current or future customers to forgo or defer purchases and/or our customers’ inability to pay for our products may adversely affect our earnings and cash flow. A recession could also adversely affect our future cost of debt and equity. Any inability to obtain adequate financing from debt and equity sources could force us to self-fund strategic initiatives or even forgo some opportunities, potentially harming our financial position, results of operations, and liquidity.

Our operations depend on our production facilities throughout the world. These production facilities are subject to physical and other risks that could disrupt production.

Our production facilities could be damaged or disrupted by a natural disaster, labor strike, war, political unrest, terrorist activity or a pandemic. Several of our production facilities are located in California, and thus are in areas with above average seismic activity and may also be at risk of damage in wildfires. Although we have obtained property damage and business interruption insurance for our production facilities, a major catastrophe such as an earthquake or other natural disaster at any of our sites, or significant labor strikes, work stoppage, political unrest, war or terrorist activities in any of the areas where we conduct operations, could result in a prolonged interruption of our business. Any disruption resulting from these events could cause significant delays in shipments of products and the loss of sales and customers. We cannot assure you that we will have insurance to adequately compensate us for any of these events.

Political and economic changes in foreign countries and markets, including foreign currency fluctuations, may have a material effect on our operating results.

Foreign sales originating from non-U.S. locations were approximately 50% of our total sales in fiscal 2013, and we have manufacturing facilities in a number of foreign countries. A substantial portion of our Avionics & Controls operations is based in Canada and the U.K., and a substantial portion of our Sensors & Systems operations is based in the U.K. and France. We also have manufacturing operations in China, the Dominican Republic, Germany, India, Japan, Mexico, and Morocco. Doing business in foreign countries is subject to numerous risks, including political and economic instability, restrictive trade policies of foreign governments, economic conditions in local markets, health concerns, inconsistent product regulation or unexpected changes in regulatory and other legal requirements by foreign agencies or governments, the imposition of product tariffs and the burdens of complying with a wide variety of international and U.S. export laws and differing regulatory requirements. To the extent that foreign sales are transacted in a foreign currency, we are subject to the risk of losses due to foreign currency fluctuations. In addition, we have substantial assets denominated in foreign currencies, primarily the Canadian dollar, U.K. pound and euro, that are not offset by liabilities denominated in those foreign currencies. These net foreign currency investments are subject to material changes in the event of fluctuations in foreign currencies against the U.S. dollar.

A downturn in the aircraft market could adversely affect our business.

The aerospace industry is cyclical in nature and affected by periodic downturns that are beyond our control. The principal customers for manufacturers of commercial aircraft are the commercial and regional airlines, which can be adversely affected by a number of factors, including a recession, increasing fuel and labor costs, intense price competition, outbreak

13

of infectious disease and terrorist attacks, as well as economic cycles, all of which can be unpredictable and are outside our control. Any decrease in demand resulting from a downturn in the market could adversely affect our business, financial condition and results of operations.

We may not be able to compete effectively.

Our products and services are affected by varying degrees of competition. We compete with other companies and divisions and units of larger companies in most markets we serve, many of which have greater sales volumes or financial, technological or marketing resources than we do. Our principal competitors include: Astronautics, BAE, Bose, Eaton, ECE, Elbit, EMS, GE Aerospace, Honeywell, IAI, L-3, Otto Controls, RAFI, Rockwell Collins, SELEX, Telephonics, Thales, Ultra Electronics, and Universal Avionics Systems Corporation in our Avionics & Controls segment; Ametek, Amphenol, Eaton, ECE, Goodrich, Hamilton Sundstrand, MPC Products, Meggitt, STPI-Deutsch, and TE Connectivity in our Sensors & Systems segment; and Chemring, Doncasters, Hi-Temp, J&M, JPR Hutchinson, Kmass, Meggitt (including Dunlop Standard Aerospace Group), Rheinmetall, Trelleborg, ULVA, and UMPCO in our Advanced Materials segment. The principal competitive factors in the commercial markets in which we participate are product performance, service and price. Maintaining product performance requires expenditures in research and development that lead to product improvement and new product introduction. Companies with more substantial financial resources may have a better ability to make such expenditures. We cannot assure that we will be able to continue to successfully compete in our markets, which could adversely affect our business, financial condition and results of operations.

Our backlog is subject to modification or termination, which may reduce our sales in future periods.

We currently have a backlog of orders based on our contracts with customers. Under many of our contracts, our customers may unilaterally modify or terminate their orders at any time. In addition, the maximum contract value specified under a government contract awarded to us is not necessarily indicative of the sales that we will realize under that contract. For example, we are a sole-source prime contractor for many different military programs with the U.S. Department of Defense. We depend heavily on the government contracts underlying these programs. Over its lifetime, a program may be implemented by the award of many different individual contracts and subcontracts. The funding of government programs is subject to congressional appropriation.

Changes in defense procurement models may make it more difficult for us to successfully bid on projects as a prime contractor and limit sole-source opportunities available to us.

In recent years, the trend in combat system design and development appears to be evolving toward the technological integration of various battlefield components, including combat vehicles, command and control network communications, advanced technology artillery systems and robotics. If the U.S. military procurement approach continues to require this kind of overall battlefield combat system integration, we expect to be subject to increased competition from aerospace and defense companies which have significantly greater resources than we do.

We may lose money or generate less than expected profits on our fixed-price contracts.

Our customers set demanding specifications for product performance, reliability and cost. Some of our government contracts and subcontracts provide for a predetermined, fixed price for the products we make regardless of the costs we incur. Therefore, we must absorb cost overruns, notwithstanding the difficulty of estimating all of the costs we will incur in performing these contracts and in projecting the ultimate level of sales that we may achieve. Our failure to anticipate technical problems, estimate costs accurately, integrate technical processes effectively or control costs during performance of a fixed-price contract may reduce the profitability of a fixed-price contract or cause a loss. While we believe that we have recorded adequate provisions in our financial statements for losses on our fixed-price contracts as required under GAAP, we cannot assure that our contract loss provisions will be adequate to cover all actual future losses. Therefore, we may incur losses on fixed-price contracts that we had expected to be profitable, or such contracts may be less profitable than expected.

14

Our business is subject to government contracting regulations, and our failure to comply with such laws and regulations could harm our operating results and prospects.

We estimate that approximately 23% of our sales in fiscal 2013 were attributable to contracts in which we were either the prime contractor to, or a subcontractor to a prime contractor to, the U.S. government. As a contractor and subcontractor to the U.S. government, we must comply with laws and regulations relating to the formation, administration and performance of federal government contracts that affect how we do business with our customers and may impose added costs to our business. For example, these regulations and laws include provisions that contracts we have been awarded are subject to:

The accuracy and appropriateness of certain costs and expenses used to substantiate our direct and indirect costs for the U.S. government under both cost-plus and fixed-price contracts are subject to extensive regulation and audit by the Defense Contract Audit Agency, an arm of the U.S. Department of Defense. Responding to governmental audits, inquiries or investigations may involve significant expense and divert management attention. Our failure to comply with these or other laws and regulations could result in contract termination, suspension or debarment from contracting with the federal government, civil fines and damages, and criminal prosecution and penalties, any of which could have a material adverse effect on our operating results.

A significant portion of our business depends on U.S. government contracts, which are often subject to competitive bidding, and a failure to compete effectively or accurately anticipate the success of future projects could adversely affect our business.

We obtain many of our U.S. government contracts through a competitive bidding process that subjects us to risks associated with:

In addition, in order to win the award of developmental programs, we must be able to align our research and development and product offerings with the government’s changing concepts of national defense and defense systems. The government’s termination of, or failure to fully fund, one or more of the contracts for our programs would have a negative impact on our operating results and financial condition. Furthermore, we serve as a subcontractor on several military programs that, in large part, involve the same risks as prime contracts.

Overall, we rely on key contracts with U.S. government entities for a significant portion of our sales and business. A substantial reduction in these contracts would materially adversely affect our operating results and financial position.

The market for our products may be affected by our ability to adapt to technological change.

The rapid change of technology is a key feature of all of the markets in which our businesses operate. To succeed in the future, we will need to design, develop, manufacture, assemble, test, market, and support new products and enhancements to our existing products in a timely and cost-effective manner. Historically, our technology has been developed through internal research and development expenditures, as well as customer-sponsored research and development programs. There is no guarantee that we will continue to maintain, or benefit from, comparable levels of research and development in the future. In addition, our competitors may develop technologies and products that are more effective than those we develop or that render our technology and products obsolete or noncompetitive. Furthermore, our products could become unmarketable if new industry standards emerge. We cannot assure that our existing products will not require significant modifications in the future to remain competitive or that new products we introduce will be accepted by our customers, nor can we assure that we will successfully identify new opportunities and continue to have the needed financial resources to develop new products in a timely or cost-effective manner.

15

The airline industry is heavily regulated and if we fail to comply with applicable requirements, our results of operations could suffer.

Governmental agencies throughout the world, including the U.S. Federal Aviation Administration (FAA), prescribe standards and qualification requirements for aircraft components, including virtually all commercial airline and general aviation products, as well as regulations regarding the repair and overhaul of aircraft engines. Specific regulations vary from country to country, although compliance with FAA requirements generally satisfies regulatory requirements in other countries. We include, with the replacement parts that we sell to our customers, documentation certifying that each part complies with applicable regulatory requirements and meets applicable standards of airworthiness established by the FAA or the equivalent regulatory agencies in other countries. In order to sell our products, we and the products we manufacture must also be certified by our individual OEM customers. If any of the material authorizations or approvals qualifying us to supply our products is revoked or suspended, then the sale of the subject product would be prohibited by law, which would have an adverse effect on our business, financial condition and results of operations.

From time to time, the FAA or equivalent regulatory agencies in other countries propose new regulations or changes to existing regulations, which are usually more stringent than existing regulations. If these proposed regulations are adopted and enacted, we may incur significant additional costs to achieve compliance, which could have a material adverse effect on our business, financial condition and results of operations.

We depend on the continued contributions of our executive officers and other key management, each of whom would be difficult to replace.

Our future success depends to a significant degree upon the continued contributions of our senior management and our ability to attract and retain other highly qualified management personnel. We face competition for management from other companies and organizations. Therefore, we may not be able to retain our existing management personnel or fill new management positions or vacancies created by expansion or turnover at our existing compensation levels. Although we have entered into change of control agreements with members of senior management, we do not have employment contracts with our key executives, nor have we purchased “key-person” insurance on the lives of any of our key officers or management personnel to reduce the impact to our company that the loss of any of them would cause. Specifically, the loss of any of our executive officers would disrupt our operations and divert the time and attention of our remaining officers. Additionally, failure to attract and retain highly qualified management personnel would damage our business prospects.

If we are unable to protect our intellectual property rights adequately, the value of our products could be diminished.

Our success is dependent in part on obtaining, maintaining and enforcing our proprietary rights and our ability to avoid infringing on the proprietary rights of others. While we take precautionary steps to protect our technological advantages and intellectual property and rely in part on patent, trademark, trade secret and copyright laws, we cannot assure that the precautionary steps we have taken will completely protect our intellectual property rights. Because patent applications in the United States are maintained in secrecy until either the patent application is published or a patent is issued, we may not be aware of third-party patents, patent applications and other intellectual property relevant to our products that may block our use of our intellectual property or may be used in third-party products that compete with our products and processes. In the event a competitor successfully challenges our products, processes, patents or licenses or claims that we have infringed upon their intellectual property, we could incur substantial litigation costs defending against such claims, be required to pay royalties, license fees or other damages or be barred from using the intellectual property at issue, any of which could have a material adverse effect on our business, operating results and financial condition.

In addition to our patent rights, we also rely on unpatented technology, trade secrets and confidential information. Others may independently develop substantially equivalent information and techniques or otherwise gain access to or disclose our technology. We may not be able to protect our rights in unpatented technology, trade secrets and confidential information effectively. We require each of our employees and consultants to execute a confidentiality agreement at the commencement of an employment or consulting relationship with us. However, these agreements may not provide effective protection of our information or, in the event of unauthorized use of disclosure, they may not provide adequate remedies.

Future asbestos claims could harm our business.

We are subject to potential liabilities relating to certain products we manufactured containing asbestos. To date, our insurance has covered claims against us relating to those products. Commencing November 1, 2003, insurance coverage for asbestos claims has been unavailable. However, we continue to have some insurance coverage for exposure to asbestos contained in our products prior to that date.

16

As a result of the termination of the NASA Space Shuttle program, manufacturing of rocket engine insulation material containing asbestos ceased in July 2010. In December 2011, we dismantled our facility used to manufacture the asbestos-based insulation for the Space Shuttle program. We have an agreement with the customer for indemnification for certain losses we may incur as a result of asbestos claims relating to a product we previously manufactured, but we cannot assure that this indemnification agreement will fully protect us from losses arising from asbestos claims.

To the extent we are not insured or indemnified for losses from asbestos claims relating to our products, asbestos claims could adversely affect our operating results and our financial condition.

Environmental laws and regulations may subject us to significant liability.

Our business and our facilities are subject to a number of federal, state, local and foreign laws, regulations and ordinances governing, among other things, the use, manufacture, storage, handling and disposal of hazardous materials and certain waste products. Among these environmental laws are rules by which a current or previous owner or operator of land may be liable for the costs of investigation, removal or remediation of hazardous materials at such property. In addition, these laws typically impose liability regardless of whether the owner or operator knew of, or was responsible for, the presence of any hazardous materials. Persons who arrange for the disposal or treatment of hazardous materials may be liable for the costs of investigation, removal or remediation of such substances at the disposal or treatment site, regardless of whether the affected site is owned or operated by them.

Because we own and operate, and previously owned and operated, a number of facilities that use, manufacture, store, handle or arrange for the disposal of various hazardous materials, we may incur costs for investigation, removal and remediation, as well as capital costs, associated with compliance with environmental laws. At the time of our asset acquisition of the Electronic Warfare Passive Expendables Division of BAE Systems North America (BAE), certain environmental remedial activities were required under a Part B Permit issued to the infrared decoy flare facility by the Arkansas Department of Environmental Quality under the Federal Resource Conservation and Recovery Act. The Part B Permit was transferred to our subsidiary, Armtec, along with the remedial obligations. Under the terms of the asset purchase agreement, BAE agreed to perform and pay for these remedial obligations at the infrared decoy flare facility up to a maximum amount of $25.0 million. BAE is currently conducting monitoring activities as required under the asset purchase agreement. Although environmental costs have not been material in the past, we cannot assure that these matters, or any similar liabilities that arise in the future, will not exceed our resources, nor can we completely eliminate the risk of accidental contamination or injury from these materials.

An accident at our combustible ordnance or flare countermeasure operations could harm our business.

We are subject to potential liabilities in the event of an accident at our combustible ordnance and flare countermeasure operations. Our products are highly flammable during certain phases of the manufacturing process. Accordingly, our facilities are designed to isolate these operations from direct contact with employees. Our overall safety infrastructure is compliant with regulatory guidelines. In addition, we utilize hazard detection and intervention systems. Our employees receive safety training and participate in internal safety demonstrations. We continuously track safety effectiveness in relation to the U.S. Bureau of Labor Statistics, OSHA, and the HSE in the U.K. to help ensure performance is within industry standards. In addition, we perform on-going process safety hazard analyses, which are conducted by trained safety teams to identify risk areas that arise. We monitor progress through review of safety action reports that are produced as part of our operations. Although we believe our safety programs are robust and our compliance with our programs is high, it is possible for an accident to occur. For example, an explosion occurred in 2006 at our Wallop facility in the U.K. (causing a fatality, several minor injuries, and extensive damage to the facility). We are insured in excess of our deductible on losses from property, loss of business, and for personal liability claims from an accident; however, we may not be able to maintain insurance coverage in the future at an acceptable cost. Significant losses not covered by insurance could have a material adverse effect on our business, financial condition, and results of operations.

We may be required to defend lawsuits or pay damages in connection with the alleged or actual harm caused by our products.

We face an inherent business risk of exposure to product liability claims in the event that the use of our products is alleged to have resulted in harm to others or to property. For example, our operations expose us to potential liabilities for personal injury or death as a result of the failure of an aircraft component that has been designed, manufactured or serviced by us. We may incur significant liability if product liability lawsuits against us are successful. While we believe our current general liability and product liability insurance is adequate to protect us from future product liability claims, we cannot assure that coverage will be adequate to cover all claims that may arise. Additionally, we may not be able to maintain insurance coverage in the future at an acceptable cost. Significant losses not covered by insurance or for which third-party indemnification is not available could have a material adverse effect on our business, financial condition and results of operations.

17

Our financial performance may be adversely affected by information technology business disruptions.

Our business may be impacted by information technology attacks or failures. Cybersecurity attacks, in particular, are evolving and include, but are not limited to, malicious software, attempts to gain unauthorized access to data, and other electronic security breaches that could lead to disruptions in systems, unauthorized release of confidential or otherwise protected information and corruption of data. We have experienced cybersecurity attacks in the past and may experience them in the future, potentially with more frequency. We have taken measures to mitigate potential risks to our technology and our operations from these information technology-related potential disruptions. For example, we utilized third-party software and tools at many domestic operating locations to scan incoming email for viruses and other harmful content and to scan networks maintained by certain of our domestic operating units that exclusively perform U.S. defense work. However, given the unpredictability of the timing, nature and scope of such disruptions, we could potentially be subject to production downtimes, operational delays, other detrimental impacts on our operations or ability to provide products and services to our customers, the compromising of confidential or otherwise protected information, destruction or corruption of data, security breaches, or other manipulation or improper use of our systems or networks. We may also experience financial losses from remedial actions, loss of business or potential liability under contracts or pursuant to regulations that require us to maintain confidential and other data securely, and/or damage to our reputation. Any of these consequences could have a material adverse effect on our competitive position, results of operations, cash flows or financial condition.

Item 2.  Properties

The following table summarizes our properties that are greater than 100,000 square feet or related to a principal operation, including identification of the business segment, as of October 25, 2013:

*  The building is located on a parcel of land covering 16.1 acres that is leased by the Company.

In total, we own approximately 2,300,000 square feet and lease approximately 2,000,000 square feet of manufacturing facilities and properties.

Item 3.  Legal Proceedings

From time to time we are involved in legal proceedings arising in the ordinary course of our business. We believe adequate reserves for these liabilities have been made and that there is no litigation pending that could have a material adverse effect on our results of operations and financial condition.

We are subject to U.S. export laws and regulations, including the International Traffic in Arms Regulations (ITAR), that generally restrict the export of defense products, technical data, and defense services. We have filed voluntary reports that disclosed certain technical and administrative violations of the ITAR with the U.S. Department of State’s Directorate of Defense Trade Controls (DDTC) Office of Defense Trade Controls Compliance (DDTC Office of Compliance). To address these problems, we have made a number of investments in our export compliance functions, including: additional staffing, ongoing implementation of a new software system, employee training, and establishment of a regular compliance audit program and corrective action process. The DDTC Office of Compliance acknowledged our progress and continuing improvements, but nevertheless informed us that it intends to impose civil monetary fines and administrative sanctions based on the information it had concerning our earlier history in handling ITAR-controlled transactions, including the substance of our prior voluntary disclosures and other aspects of ITAR compliance errors. Management has been in discussions with the agency and provided supplemental information with the intent of reaching a settlement. On August 15, 2013, the DDTC Office of Compliance proposed a total penalty of $20 million, with $10 million suspended and eligible for offset credit based on verified expenditures for past and future remedial compliance measures. Based on this proposal, we estimated and recorded a $10 million charge as of July 26, 2013, for this matter. We have continued discussions with the DDTC Office of Compliance on final settlement terms, and the final settlement is subject to approval by the agency. While we cannot be certain of the outcome, management believes that the final resolution of this matter will not be materially different from our estimated accrual.

Item 7.  Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our financial statements and related notes in Item 8 of this report. This discussion and analysis contains forward-looking statements and estimates that involve risks, uncertainties and assumptions. Our actual results may differ materially from those anticipated in these forward-looking statements as a result of many factors, including, but not limited to, those discussed in the “Forward-Looking Statements” section in Item 1 of this report and the “Risk Factors” section in Item 1A of this report.

OVERVIEW

We operate our businesses in three segments: Avionics & Controls, Sensors & Systems and Advanced Materials. Our segments are structured around our technical capabilities. Sales in all segments include domestic, international, defense and commercial customers.

The Avionics & Controls segment includes avionics systems, control and communication systems, and interface technologies capabilities. Avionics systems designs and develops cockpit systems integration and avionics solutions for commercial and military applications. Control and communication systems designs and manufactures technology interface systems for military and commercial aircraft and land- and sea-based military vehicles. Additionally, control and communication systems designs and manufactures military audio and data products for severe battlefield environments, embedded communication intercept receivers for signal intelligence applications, as well as communication control systems to enhance security and aural clarity in military applications. Interface technologies manufactures and develops custom control panels and input systems for medical, industrial, military and gaming industries.

The Sensors & Systems segment includes power systems, connection technologies and advanced sensors capabilities. Power systems develops and manufactures electrical power switching and other related systems, principally for aerospace and defense customers. Connection technologies develops and manufactures highly engineered connectors for harsh environments and serves the aerospace, defense & space, power generation, rail and industrial equipment markets. Advanced sensors develops and manufactures high precision temperature and pressure sensors for aerospace and defense customers.

The Advanced Materials segment includes engineered materials and defense technologies capabilities. Engineered materials develops and manufactures thermally engineered components and high-performance elastomer products used in a wide range of commercial aerospace and military applications. Defense technologies develops and manufactures combustible ordnance components and warfare countermeasure devices for military customers.

Our current business and strategic plan focuses on the continued development of our products principally for aerospace and defense markets. We are concentrating our efforts to expand our capabilities in these markets and to anticipate the global needs of our customers and respond to such needs with comprehensive solutions. These efforts focus on continuous research and new product development, acquisitions and strategic realignments of operations to expand our capabilities as a more comprehensive supplier to our customers across our entire product offering.

On December 5, 2013, we announced the acceleration of our plans to consolidate certain facilities and create cost-efficiency through shared services in sales, general and administrative and support functions. We are currently launching integration activities in each segment and expect to record charges and expenses of approximately $40 million. We expect to incur costs of $25 million to $30 million in fiscal 2014 to support these efforts, with the balance to be incurred in fiscal 2015. The costs are mainly for severance, relocation of facilities and long-lived asset impairment losses. Expense savings on short-cycle activities will commence in fiscal 2014, with substantially more savings expected in fiscal 2015. We expect these projects to build to anticipated savings in excess of $15 million annually starting in fiscal 2016. The projects have payback periods of approximately two years.

On February 4, 2013, we acquired the Gamesman Group (Gamesman). Gamesman is a global supplier of input devices principally serving the gaming industry. Gamesman is included in the Avionics & Controls segment.

On July 26, 2011, we acquired the Souriau Group (Souriau). Souriau is a leading global supplier of highly engineered connection technologies for harsh environments. Souriau is included in our Sensors & Systems segment.

During the fourth fiscal quarter of 2013, earnings from continuing operations were $66.2 million, or $2.07 per diluted share, compared with $61.7 million, or $1.97 per diluted share, in the prior-year period.

24

Sales during the fourth fiscal quarter of 2013 were $534.2 million compared with $530.7 million in the prior-year period. Avionics & Controls segment sales increased 2.3% to $225.4 million from the prior-year period, mainly reflecting the Gamesman acquisition. Sensors & Systems sales increased 1.6% to $177.3 million and Advanced Materials sales decreased 3.2% to $131.5 million. Total sales were impacted by reductions in defense spending mainly due to the continued uncertainty of U.S. congressional budget cuts, or sequestration, on defense spending. The impact of sequestration is yet to be fully determined, and additional reductions in defense spending over the next decade could occur.

Gross margin in the fourth fiscal quarter of 2013 was 38.4% of sales compared with 38.5% in the prior-year period. Research, development and engineering decreased $1.7 million during the fourth fiscal quarter of 2013 to 4.3% of sales. Selling, general and administrative expense decreased $4.9 million during the fourth fiscal quarter of 2013 to 17.3% of sales, mainly reflecting a favorable settlement of an environmental claim.

Segment earnings (operating earnings excluding corporate expenses and other income or expense) totaled $101.2 million, or 19.0% of sales, compared with $90.3 million, or 17.0% of sales, in the prior-year period. The increase in segment earnings reflected improved operating earnings from Sensors & Systems and Advanced Materials, while Avionics & Controls earnings were even compared to the prior-year period. Avionics & Controls earnings in the fourth fiscal quarter of 2013 benefited from a gain on sale of a product line and recognition of previously deferred revenue. Operating earnings of Sensors & Systems increased due to improved gross margin and lower research, development and engineering expense. Advanced Materials earnings compared favorably to the prior-year period mainly reflecting a favorable settlement of an environmental claim and a recovery of non-recurring engineering expense from a customer. The income tax rate for the fourth fiscal quarter of 2013 was 20.4% compared to 13.0% in the prior-year period. Our income tax rate in the fourth fiscal quarter of 2012 was favorably impacted by a $1.4 million release of valuation allowance related to foreign tax credits as a result of a tax examination.

Loss from discontinued operations for the fourth fiscal quarter of 2013 was $0.3 million or $0.01 per diluted share. There was no income or loss from discontinued operations in the prior-year period.

Net income for the fourth fiscal quarter of 2013 was $65.9 million, or $2.06 per diluted share, compared with $61.7 million, or $1.97 per diluted share, in the fourth fiscal quarter of 2012.

During fiscal 2013, earnings from continuing operations was $166.0 million, or $5.23 per diluted share, compared with $112.5 million, or $3.60 per diluted share, during fiscal 2012. In fiscal 2013 we recorded a $3.5 million, or $0.11 per diluted share, impairment charge against goodwill of Racal Acoustics, Inc. (Racal Acoustics), our military headset business, which is included in our Avionics & Controls segment, due to continued weakness in Racal Acoustics’ fiscal 2013 and five-year forecast resulting from further delays and reductions in global defense programs. The results for fiscal 2013 also were impacted by a $10 million charge, or $0.32 per diluted share, related to our pending matter with the DDTC, as more fully discussed below. In the prior-year period, we recorded a $52.2 million, or $1.67 per diluted share, impairment charge against goodwill of Racal Acoustics. In fiscal 2012, all contingencies relating to a dispute between CMC Electronics, Inc. (CMC) and a former parent company were resolved, and accordingly, we recorded a gain of approximately $11.9 million or $9.5 million after tax.

During fiscal 2013, sales declined 1.1% to $1.97 billion. Gross margin increased to 36.9%. Research, development and engineering decreased $12.0 million across all segments to 4.9% of sales. Selling, general and administrative expense increased $8.3 million to 19.9% of sales, mainly due to the $10.0 million charge for the DDTC matter.

We are subject to U.S. export laws and regulations, including the International Traffic in Arms Regulations (ITAR), that generally restrict the export of defense products, technical data, and defense services. We have filed voluntary disclosure reports concerning certain technical and administrative violations of the ITAR with the U.S. Department of State’s Directorate of Defense Trade Controls (DDTC) Office of Defense Trade Controls Compliance (DDTC Office of Compliance). To address these problems, we have made a number of investments in our export compliance functions, including: additional staffing, ongoing implementation of a new software system, employee training, and establishment of a regular compliance audit program and corrective action process. The DDTC Office of Compliance acknowledged our progress and continuing improvements, but nevertheless informed us that it intends to impose civil monetary fines and administrative sanctions based on the information it had concerning our earlier history in handling ITAR-controlled transactions, including the substance of our prior voluntary disclosures and other aspects of ITAR compliance errors. Management has been in discussions with the agency and provided supplemental information with the intent of reaching a settlement. On August 15, 2013, the DDTC Office of Compliance proposed a total penalty of $20 million, with $10 million suspended and eligible for offset credit based on verified expenditures for past and future remedial compliance measures. Based on this proposal, we estimated and recorded a $10 million charge in fiscal 2013. We have continued discussions with the DDTC Office of Compliance on final settlement terms, and the final settlement is subject to approval by the

25

agency. While we cannot be certain of the outcome, management believes that the final resolution of this matter will not be materially different from our estimated accrual. Management believes that the additional expense associated with improving our compliance program will increase compliance cost about $10 million in fiscal 2014 compared to the prior-year period.

The income tax rate for fiscal 2013 was 15.2% compared with 20.9% for fiscal 2012, mainly reflecting the impact of fiscal 2012 expense associated with the Racal Acoustics impairment, which was not deductible for income tax purposes.

Loss from discontinued operations for fiscal 2013 was $1.3 million or $0.04 per diluted share. There was no income or loss from discontinued operations in the prior-year period.

Net income for fiscal 2013 was $164.7 million, or $5.19 per diluted share, compared with $112.5 million, or $3.60 per diluted share, for fiscal 2012.

Cash flows from operating activities were $250.8 million in fiscal 2013 compared to $194.2 million in the prior-year period.

Results of Operations

Fiscal 2013 Compared with Fiscal 2012

Sales for fiscal 2013 decreased 1.1% over the prior year. Sales by segment were as follows:

The $18.4 million, or 2.3% decrease in Avionics & Controls mainly reflected decreased sales volumes of avionics systems of $12 million and control and communication systems of $41 million, partially offset by an increase in sales volumes of interface technologies. The decrease in avionics systems was principally due to lower cockpit integration sales volumes for the T-6B military trainer and retrofits for military transport aircraft. The decrease in control and communication sales mainly reflected a $28 million decrease in sales of communication intercept receivers for signal intelligence applications and a $7 million decrease in communication systems to enhance security and aural clarity in military communication applications. The increase in interface technologies was principally due to incremental sales from the Gamesman acquisition.

Sensors & Systems sales were even with the prior-year period. A $6 million decrease in sales of advanced sensors was offset by an equal increase in power systems sales. The decrease in advanced sensors sales reflected lower OEM and aftermarket sales. The increase in power systems sales principally reflected retrofit sales. Connection technologies sales were even with the prior-year period reflecting a weaker euro relative to the U.S. dollar compared to the prior-year period. Strong sales of connection technologies for commercial aviation were offset by weaker sales for industrial equipment and defense applications.

The $3.7 million, or 0.7% decrease, in sales of Advanced Materials principally reflected lower sales volumes of combustible ordnance reflecting the impact from sequestration, partially offset by higher international sales of flare countermeasures.

Foreign sales originating from non-U.S. locations, including export sales by domestic operations, totaled $1.2 billion in both fiscal 2013 and 2012, and accounted for 59.5% and 59.2% of our sales in fiscal 2013 and 2012, respectively.

Overall, gross margin as a percentage of sales was 36.9% and 36.1% in fiscal 2013 and 2012, respectively. Gross profit was $726.0 million and $719.0 million in fiscal 2013 and 2012, respectively.

Avionics & Controls segment gross margin was 38.5% and 39.5% for fiscal 2013 and 2012, respectively. Segment gross profit was $296.9 million compared to $311.7 million in the prior-year period. The decrease in gross profit mainly reflected lower sales of communication intercept receivers for signal intelligence applications and communication systems to enhance security and aural clarity in military communication applications.

26

Sensors & Systems segment gross margin was 37.4% and 34.8% for fiscal 2013 and 2012, respectively. Segment gross profit was $262.8 million and $244.6 million for fiscal 2013 and 2012, respectively. The increase in gross profit was mainly due to increased gross profit in connection technologies, reflecting a $12 million charge recorded in the first quarter of fiscal 2012 due to recording Souriau’s acquired inventory at its fair value. Segment gross profit also benefited from strong retrofit sales of power systems.

Advanced Materials segment gross margin was 33.5% and 32.5% for fiscal 2013 and 2012, respectively. Segment gross profit was $166.2 million and $162.7 million for fiscal 2013 and 2012, respectively. The increase in gross profit was principally due to higher sales of elastomer materials primarily for defense applications.

Selling, general and administrative expenses (which include corporate expenses) increased to $391.2 million, or 19.9% of sales, in fiscal 2013 compared with $382.9 million, or 19.2% of sales, in fiscal 2012. The $8.3 million increase in selling, general and administrative expenses reflects a $19 million increase in corporate expense, a $5.1 million reduction in Avionics & Controls and an $8.7 million reduction in Advanced Materials expense. The increase in corporate expense was mainly due to the $10 million loss contingency related to the DDTC matter, professional fees for regulatory compliance and expenses related to our European headquarters. The decrease in Avionics & Controls expense reflected a $1 million reduction of our allowance for doubtful accounts for Hawker Beechcraft; in addition, the prior-year period reflected bad debt expense of $2.3 million due to the bankruptcy of Hawker Beechcraft. The $8.7 million decrease in Advanced Materials mainly reflected recovery of a prior-year $2.4 million estimated liability for an environmental claim. The claim was settled in fiscal 2013 for $0.5 million and fully indemnified by the prior owner of the business. Advanced Materials selling, general and administrative expenses were also lower due to decreased legal, bad debt and severance expenses.

Research, development and related engineering spending decreased to $95.7 million, or 4.9% of sales, in fiscal 2013 compared with $107.7 million, or 5.4% of sales, in fiscal 2012. The decrease in research, development and engineering spending principally reflects lower spending on avionics systems.

Segment earnings for fiscal 2013 were $300.1 million, or 15.2% of sales, compared with $219.4 million, or 11.0% of sales, for fiscal 2012. The increase in segment earnings reflects the $52.2 million impairment charge against goodwill of Racal Acoustics in fiscal 2012. We also recorded an impairment charge of $3.5 million against goodwill of Racal Acoustics in the third fiscal quarter of 2013. If the impairment charges in each period in fiscal 2013 and 2012 are excluded, segment earnings totaled $303.5 million, or 15.4% of sales, and $271.5 million, or 13.6% of sales, for fiscal 2013 and 2012, respectively.

Avionics & Controls segment earnings were $103.2 million, or 13.4% of sales, in fiscal 2013 compared with $54.9 million, or 7.0% of sales, in fiscal 2012. Excluding the impairment charges in both fiscal 2013 and 2012 referred to above, segment earnings were $106.7 million, or 13.8% of sales, and $107.1 million, or 13.6% of sales, in fiscal 2013 and 2012, respectively. Control and communication systems earnings decreased $12 million mainly due to decreased sales of communication intercept receivers for signal intelligence applications. Avionics systems earnings increased from the prior period reflecting decreased research, development and engineering expense of $7 million. Segment earnings also benefited from a $2.3 million gain on sale of a product line and certain contractual recoveries of non-recurring engineering expense.

Sensors & Systems segment earnings were $89.7 million, or 12.8% of sales, in fiscal 2013 compared with $70.9 million, or 10.1% of sales, in fiscal 2012, reflecting the $12.0 million charge in 2012 due to recording Souriau’s acquired inventory at its fair value. Sensors & Systems earnings also benefited from increased earnings of power systems from improved gross margin.

Advanced Materials segment earnings were $107.2 million, or 21.6% of sales, in fiscal 2013 compared with $93.5 million, or 18.7% of sales, in fiscal 2012, primarily reflecting increased earnings from sales of engineered materials of $7 million, partially offset by weaker earnings from sales of defense technologies. The increase in engineered materials earnings reflected the increase in gross profit.

In the fourth quarter of fiscal 2013, we sold a product line in our Avionics & Controls segment and realized a $2.3 million gain.

In the second quarter of fiscal 2012, all contingencies relating to a dispute between CMC and a former parent company were resolved, and accordingly, we recorded a gain of approximately $11.9 million or $9.5 million after tax.

Interest expense decreased to $39.7 million during fiscal 2013 compared with $46.2 million in the prior year, reflecting lower borrowings.

27

The income tax rate for fiscal 2013 was 15.2% compared with 20.9% in fiscal 2012. The tax rate was lower than the statutory rate, as both years benefited from various tax credits and certain foreign interest expense deductions. During fiscal 2013, we recognized $12.7 million of discrete tax benefits principally related to the following items. The first item was approximately $1.5 million of tax benefits due to the retroactive extension of the U.S. federal research and experimentation credits. The second item was approximately $2.5 million of tax benefits related to the settlement of U.S. and foreign tax examinations. The third item was a $4.9 million tax benefit related to the release of tax reserves due to the expiration of a statute of limitations. The fourth item was a $3.8 million reduction of net deferred income tax liabilities as a result of the enactment of tax laws reducing the U.K. statutory income tax rate.

In fiscal 2012, we recognized $8.7 million of discrete income tax benefits as a result of the following items. The first item was a $2.3 million tax benefit due to a change in French tax laws associated with the holding company structure and the financing of the Souriau acquisition. The second item was a $2.9 million reduction of the U.K. statutory income tax rate. The third item was a $2.1 million tax benefit as a result of reconciling the prior-year’s income tax return to the U.S. income tax provision and settlement of tax examinations. The fourth item was a $1.4 million release of a valuation allowance related to foreign tax credits as a result of a tax examination.

We expect the income tax rate to be in the range of 21% to 22% in fiscal 2014.

To the extent that sales are transacted in a currency other than the functional currency of the operating unit, we are subject to foreign currency fluctuation risk.

We use forward contracts to hedge our foreign currency exchange risk. To the extent that these hedges qualify under U.S. GAAP, the amount of gain or loss is deferred in Accumulated Other Comprehensive Income (AOCI) until the related sale occurs. Also, we are subject to foreign currency gains or losses from embedded derivatives on backlog denominated in a currency other than the functional currency of our operating companies or its customers. Gains and losses on forward contracts, embedded derivatives, and revaluation of assets and liabilities denominated in a currency other than the functional currency of the Company for fiscal 2013 and 2012 were as follows:

In Thousands

Gain (Loss)

New orders for fiscal 2013 were $1.9 billion compared with $2.1 billion for fiscal 2012. Orders by segment for fiscal 2013 decreased for our Avionics & Controls and Advanced Materials segments compared to the prior-year period and increased for Sensors & Systems compared to the prior-year period. The decrease in orders for Avionics & Controls and Advanced Materials was mainly due to the effects of sequestration. Backlog at the end of fiscal 2013 and 2012 was $1.3 billion. Approximately $332 million is scheduled to be delivered after fiscal 2014. Backlog is subject to cancellation until delivery.

28

Fiscal 2012 Compared with Fiscal 2011

Sales for fiscal 2012 increased 16.0% over the prior year. Sales by segment were as follows:

The $51.9 million, or 6.2% decrease, in Avionics & Controls mainly reflected decreased sales volumes of avionics systems of $64 million and communication systems offset by an increase in sales volumes of control systems. The decrease in avionics systems was principally due to lower cockpit integration sales volumes for the T-6B military trainer and retrofits for military transport aircraft. The decrease in sales for the T-6B was due the bankruptcy filing of Hawker Beechcraft. The decrease in segment sales also reflected a $16 million decrease in sales of hearing protection headsets due to reduced demand and order delays, of which about 50% was offset by higher sales of communication intercept receivers for signal intelligence applications. The increase in control systems sales was mainly due to higher sales to OEM customers. The prior-year period benefited from a $4.4 million retroactive price settlement due to product scope changes.

The $287.8 million, or 69.4% increase, in Sensors & Systems principally reflected incremental sales from the Souriau acquisition of $250 million and increased sales volume of advanced sensors and power systems of $36 million. About 60% of the increase in advanced sensors and power systems sales reflected increased sales of power systems due to higher demand for commercial aviation products. The increase in advanced sensors reflected higher OEM sales and strong aftermarket demand for aerospace and industrial customers. Sales in fiscal 2012 reflected a weaker euro relative to the U.S. dollar compared with the prior-year period.

The $38.5 million, or 8.3% increase, in sales of Advanced Materials principally reflected increased sales volumes of engineered materials of $40 million, partially offset by decreased sales volumes of defense technologies. The increase in engineered materials primarily reflected strong demand for elastomer and insulation materials for commercial aviation products. The decrease in defense technologies principally reflected a decrease in sales of non-U.S. countermeasure flares due to reduced demand and order delays as well as lower demand for combustible ordnance.

Foreign sales originating from non-U.S. locations, including export sales by domestic operations, totaled $1.2 billion and $971.0 million, and accounted for 59.2% and 56.5% of our sales in fiscal 2012 and 2011, respectively.

Overall, gross margin as a percentage of sales was 36.1% and 34.3% in fiscal 2012 and 2011, respectively. Gross profit was $719.0 million and $589.7 million in fiscal 2012 and 2011, respectively.

Avionics & Controls segment gross margin was 39.5% and 38.8% for fiscal 2012 and 2011, respectively. Segment gross profit was $311.7 million compared to $326.5 million in the prior-year period. The decrease in gross profit was mainly due to lower sales volumes for the T-6B military trainer cockpit and retrofits of military aircraft, partially offset by increased gross profit of our avionics software testing business.

Sensors & Systems segment gross margin was 34.8% and 28.3% for fiscal 2012 and 2011, respectively. Segment gross profit was $244.6 million and $117.4 million for fiscal 2012 and 2011, respectively. Approximately 10% of the increase in gross profit reflected strong demand for power systems for commercial aviation applications. Approximately 85% of the increase in gross profit was due to incremental gross profit from the Souriau acquisition. Souriau’s gross profit was impacted by a $12 million charge in the first fiscal quarter of 2012 due to recording Souriau’s acquired inventory at its fair value. The prior-year period included a $27.9 million inventory fair value adjustment, recognized principally in the fourth fiscal quarter of 2011.

Advanced Materials segment gross margin was 32.5% and 31.6% for fiscal 2012 and 2011, respectively. Segment gross profit was $162.7 million and $145.8 million for fiscal 2012 and 2011, respectively. The increase in gross profit was principally due to higher sales of elastomer materials and insulation materials primarily for commercial aviation applications. Gross profit on defense technologies increased slightly, principally reflecting an increase in gross profit and margin on flare countermeasures, partially offset by lower gross profit on combustible ordnance due to decreased sales volumes.

29

Selling, general and administrative expenses (which include corporate expenses) increased to $382.9 million, or 19.2% of sales, in fiscal 2012 compared with $304.2 million, or 17.7% of sales, in fiscal 2011. The increase in selling, general and administrative expense principally reflected a $65.1 million increase in selling, general and administrative expense at our Sensors & Systems segment due to incremental selling, general and administrative expense from the Souriau acquisition. Selling, general and administrative expense increased $19.4 million at Avionics & Controls and Advanced Materials. This increase reflects a $2.8 million increase in bad debt due to the bankruptcy filing of Hawker Beechcraft, $5 million in incremental selling, general and administrative expense from the Eclipse acquisition, and $4.3 million in severance costs. Corporate expense decreased $5.8 million from fiscal 2011, principally reflecting lower acquisition-related expenses.

Research, development and related engineering spending increased to $107.7 million, or 5.4% of sales, in fiscal 2012 compared with $94.5 million, or 5.5% of sales, in fiscal 2011. The $13.2 million increase in research, development and related engineering expense principally reflects the incremental spending of $9 million on connection technologies reflecting a full-year impact due to the acquisition of Souriau and $6 million on power systems.

Segment earnings for fiscal 2012 were $219.4 million, or 11.0% of sales, compared with $240.0 million, or 14.0% of sales, for fiscal 2011. The decrease in segment earnings reflects the $52.2 million impairment charge against goodwill of Racal Acoustics. If the impairment charge is excluded, segment earnings totaled $271.5 million, or 13.6% of sales, for fiscal 2012.

Avionics & Controls segment earnings were $54.9 million, or 7.0% of sales, in fiscal 2012 compared with $135.2 million, or 16.1% of sales, in fiscal 2011. Excluding the $52.2 million impairment charge, segment earnings were $107.1 million, or 13.6% of sales, in fiscal 2012. The decrease in segment earnings from the prior-year period reflects a $22 million decrease in avionics systems earnings and a $5 million decrease in control systems earnings. Avionics systems earnings were impacted by decreased gross profit and a $2.3 million bad debt expense due to the bankruptcy of Hawker Beechcraft, partially offset by a decrease in spending on research, development and engineering. Control systems earnings were impacted by an increase in research, development and engineering expense. Additionally, the second fiscal quarter of 2011 benefited from a $1.1 million recovery of non-recurring engineering expense upon settlement with a customer of control systems.

Sensors & Systems segment earnings were $70.9 million, or 10.1% of sales, in fiscal 2012 compared with $22.5 million, or 5.4% of sales, in fiscal 2011, principally reflecting $40 million in incremental earnings from the Souriau acquisition and increases in sales in both power systems and advanced sensors. Souriau incurred an operating loss of $22.4 million in fiscal 2011 principally reflecting the inventory fair value adjustment referenced above. Power systems benefited from increased gross profits, partially offset by higher research, development and engineering spending. Advanced sensors benefited from increased gross profits mainly due to higher aftermarket demand and a $1.9 million recovery of non-recurring engineering and higher French tax credits on research, development and engineering expense.

Advanced Materials segment earnings were $93.5 million, or 18.7% of sales, in fiscal 2012 compared with $82.3 million, or 17.8% of sales, in fiscal 2011, primarily reflecting increased earnings from sales of engineered materials of $9 million and improved earnings from sales of defense technologies. The increase in engineered materials earnings reflected the increase in gross profit. The prior-year period benefited from a $3.2 million gain on sale of a facility, partially offset by a $1.7 million increase in an estimated liability for an environmental issue, which was paid in fiscal 2012. The improvement in results for defense technologies principally reflected an increase in earnings for countermeasures operations partially offset by decreased earnings of combustible ordnance of $3 million.

Prior to our March 2007 acquisition of CMC, CMC was involved in a transaction in which CMC shareholders had a limited amount of time in which to tender their shares in exchange for cash. In May 2008, after the prescribed time period had expired, CAD $11.8 million remained unclaimed. As a result, the paying agent returned the unclaimed amount to CMC in accordance with Canadian law. In December 2008, CMC’s former parent company instituted a legal action against the paying agent, alleging negligence and breached contract terms by returning the funds to CMC. The plaintiff lost at trial and appealed. In the second quarter of fiscal 2012, CMC received notice that the plaintiff abandoned its appeal. In addition, CMC and the paying agent settled all remaining issues. All contingencies relating to this matter were resolved, and accordingly, the Company recorded a gain of approximately CAD $11.8 million or $11.9 million, or $9.5 million after tax, in the second fiscal quarter of 2012.

Interest expense increased to $46.2 million during fiscal 2012 compared with $40.2 million in the prior year, reflecting higher borrowings.

The income tax rate for fiscal 2012 was 20.9% compared with 15.7% in fiscal 2011. The tax rate was lower than the statutory rate, as both years benefited from various tax credits and certain foreign interest expense deductions. During

30

fiscal 2012, we recognized $8.7 million of discrete income tax benefits as a result of the following items: The first item was a $2.3 million tax benefit due to a change in French tax laws associated with the holding company structure and the financing of the Souriau acquisition. The second item was a $2.9 million reduction of the U.K. statutory income tax rate. The third item was a $2.1 million tax benefit as a result of reconciling the prior year’s income tax return to the U.S. income tax provision and settlement of tax examinations. The fourth item was a $1.4 million release of valuation allowance related to foreign tax credits as a result of a tax examination.

In fiscal 2011, we recognized $11.4 million of discrete income tax benefits as result of the following items. The first item was $3.1 million of income tax benefits due to the retroactive extension of the U.S. federal research and experimentation credits and the release of a valuation allowance related to a net operating loss of an acquired subsidiary. The second item was $5.6 million of income tax benefits associated with net operating losses of an acquired subsidiary as a result of concluding a tax examination. The third item was $3.5 million of net reduction of deferred income tax liabilities as a result of a reduction in the U.K. statutory income tax rate. The fourth item was $0.8 million of income tax expense as a result of reconciling the prior-year’s income tax returns to the prior year’s provision for income tax.

To the extent that sales are transacted in a currency other than the functional currency of the operating unit, we are subject to foreign currency fluctuation risk.

We use forward contracts to hedge our foreign currency exchange risk. To the extent that these hedges qualify under U.S. GAAP, the amount of gain or loss is deferred in Accumulated Other Comprehensive Income (AOCI) until the related sale occurs. Also, we are subject to foreign currency gains or losses from embedded derivatives on backlog denominated in a currency other than the functional currency of our operating companies or its customers. Gains and losses on forward contracts, embedded derivatives, and revaluation of assets and liabilities denominated in a currency other than the functional currency of the Company for fiscal 2012 and 2011 were as follows:

New orders for fiscal 2012 were $2.1 billion compared with $1.9 billion in fiscal 2011. Orders increased across all our segments. Backlog at the end of fiscal 2012 and 2011 was $1.3 billion.

Liquidity and Capital Resources

Working Capital and Statement of Cash Flows

Cash and cash equivalents at the end of fiscal 2013 totaled $179.2 million, an increase of $18.5 million from the prior year. Net working capital increased to $683.6 million at the end of fiscal 2013 from $639.3 million at the end of the prior year.

Cash flows from operating activities were $250.8 million and $194.2 million in fiscal 2013 and 2012, respectively. The increase principally reflected higher net earnings. Sources and uses of cash flows from operating activities principally consisted of cash received from the sale of products and cash payments for material, labor and operating expense.

Cash flows used by investing activities were $93.7 million and $48.5 million in fiscal 2013 and 2012, respectively. Cash flows used by investing activities in fiscal 2013 principally reflected cash paid for acquisitions of $40.7 million, net of cash acquired, and capital expenditures of $55.3 million. Cash flows used by investing activities in fiscal 2012 principally reflected the use of cash for the purchase of capital assets of $49.4 million.

Cash flows used by financing activities were $141.0 million and $167.8 million in fiscal 2013 and 2012, respectively. Cash flows used by financing activities in fiscal 2013 primarily reflected proceeds from our new credit facility of $175.0 million and repayment of long-term debt and credit facilities of $345.4 million. Cash flows used by financing activities in fiscal 2012 primarily reflected cash repayments of our long-term debt and credit facilities of $223.1 million.

Capital Expenditures

Net property, plant and equipment was $371.2 million at the end of fiscal 2013 compared with $356.4 million at the end of the prior year. Capital expenditures for fiscal 2013 and 2012 were $55.3 million and $49.4 million, respectively (excluding

31

acquisitions), and included facilities, machinery, equipment and enhancements to information technology systems. Capital expenditures are anticipated to approximate $75.0 million for fiscal 2014. We will continue to support expansion through investments in infrastructure including machinery, equipment, and information systems.

Acquisitions

On December 20, 2013, we acquired Sunbank Family of Companies, LLC (Sunbank) for approximately $45 million and up to $5 million in contingent consideration based upon achievement of certain sales levels over a two-year period. Sunbank is a manufacturer of electrical cable accessories, connectors and flexible conduit systems. Sunbank is included in the Sensors & Systems segment. The acquisition was funded under our credit facility and available cash.

On February 4, 2013, we acquired the Gamesman Group (Gamesman) for $40.8 million. Gamesman is a global supplier of input devices principally serving the gaming industry. Gamesman is included in our Avionics & Controls segment.

On July 26, 2011, we acquired the Souriau Group (Souriau) for $726.7 million, net of acquired cash. Souriau is a leading global supplier of highly engineered connectors for harsh environments serving aerospace, defense & space, power generation, rail, and industrial equipment markets. Souriau is included in our Sensors & Systems segment.

On December 30, 2010, we acquired Eclipse Electronic Systems, Inc. (Eclipse) for $123.8 million. Eclipse is a designer and manufacturer of embedded communication intercept receivers for signal intelligence applications. Eclipse is included in our Avionics & Controls segment.

Debt Financing

Total debt decreased $159.5 million from the prior year to approximately $689.1 million at the end of fiscal 2013. Total debt outstanding at the end of fiscal 2013 consisted of $250.0 million of 2020 Notes, $170.6 million of the U.S. Term Loan, $24.8 million (€18.0 million) under our Euro Term Loan, $130.0 million in borrowings under our secured credit facility, $56.9 million government refundable advances, $56.2 million under capital lease obligations, and $0.5 million in various foreign currency debt agreements and other debt agreements.

In April 2013, we amended the secured credit facility to provide for $175.0 million term loan (U.S. Term Loan). The interest rate on the U.S. Term Loan ranges from LIBOR plus 1.5% to LIBOR plus 2.25%, depending on the leverage ratios at the time the funds are drawn. At October 25, 2013, we had $170.6 million outstanding under the U.S. Term Loan at an interest rate of LIBOR plus 1.75%, which is currently 1.93%. The loan amortizes at 1.25% of the original principal balance quarterly through March 2016, with the remaining balance due in July 2016.

In July 2011, we amended the secured credit facility to provide for a new €125.0 million term loan (Euro Term Loan). The interest rate on the Euro Term Loan ranges from euro LIBOR plus 1.5% to euro LIBOR plus 2.25%, depending on the leverage ratios at the time the funds are drawn. At October 25, 2013, we had €18.0 million outstanding or $24.8 million under the Euro Term Loan at an interest rate of euro LIBOR plus 1.75%, which is currently 1.84%. The loan amortizes at 1.25% of the original principal balance quarterly through March 2016, with the remaining balance due in July 2016.

In March 2011, we entered into a secured credit facility for $460.0 million made available through a group of banks. The credit facility is secured by substantially all of our assets and interest is based on standard inter-bank offering rates. The credit facility expires in July 2016. The interest rate ranges from LIBOR plus 1.5% to LIBOR plus 2.25%, depending on the leverage ratios at the time the funds are drawn. At October 25, 2013, we had $130.0 million outstanding under the secured credit facility at an interest rate of LIBOR plus 1.75%, which is currently 1.93%. An additional $66.2 million of unsecured foreign currency credit facilities have been extended by foreign banks for a total of $526.2 million available companywide. Available credit under the above credit facilities was $363.5 million at fiscal 2013 year end, when reduced by outstanding borrowings of $130.0 million and letters of credit of $32.7 million.

On August 2, 2010, we issued $250.0 million of 2020 Notes requiring semi-annual interest payments in March and September of each year until maturity. The net proceeds from the sale of the notes, after deducting $4.4 million of debt issuance cost, were $245.6 million. The 2020 Notes are general unsecured senior obligations of the company. The 2020 Notes are guaranteed, jointly and severally on a senior basis, by all the existing and future domestic subsidiaries of the company unless designated as an “unrestricted subsidiary,” and those foreign subsidiaries that executed related subsidiary guarantees under the indenture covering the 2020 Notes. The 2020 Notes are subject to redemption at the option of the company at any time prior to August 1, 2015, at a price equal to 100% of the principal amount, plus any accrued interest to the date of redemption and a make-whole provision. The 2020 Notes are also subject to redemption at the option of the company, in whole or in part, on or after August 1, 2015, at redemption prices starting at 103.500% of the principal amount plus accrued interest during the period beginning August 1, 2015, and declining annually to 100% of principal and accrued interest on or after August 1, 2018.

32

In April 2013, we redeemed the $175.0 million 6.625% Senior Notes due March 2017 (2017 Notes). In connection with the redemption, we wrote off $1.3 million in unamortized debt issuance costs as a charge against interest expense. In addition, we incurred a $3.9 million redemption premium and received proceeds of $2.9 million from the termination of its $175.0 million interest rate swap agreements. As a result, the redemption of the 2017 Notes resulted in a net loss of $0.9 million on extinguishment of debt.

We believe cash on hand, funds generated from operations and other available debt facilities are sufficient to fund operating cash requirements and capital expenditures through fiscal 2014. We believe we will have adequate access to capital markets to fund future acquisitions.

Permanent Investment of Undistributed Earnings of Foreign Subsidiaries

Our non-U.S. subsidiaries have $167.2 million in cash and cash equivalents at October 25, 2013. Cash and cash equivalents at our U.S. parent and subsidiaries aggregated $12.0 million at October 25, 2013, and cash flow from these operations is sufficient to fund working capital, capital expenditures, acquisitions and debt repayments of our domestic operations. We have available credit to our U.S. parent and subsidiaries of $330.0 million on our U.S. secured credit facility. The earnings of our non-U.S. subsidiaries are considered to be indefinitely invested, and accordingly, no provision for federal income taxes has been made on accumulated earnings of foreign subsidiaries. The amount of the unrecognized deferred income tax liability for temporary differences related to investments in foreign subsidiaries is not practical to determine because of the complexities regarding the calculation of unremitted earnings and the potential for tax credits.

Government Refundable Advances

Government refundable advances consist of payments received from the Canadian government to assist in the research and development related to commercial aviation. These advances totaled $56.9 million and $51.8 million at October 25, 2013, and October 26, 2012, respectively. The repayment of the advances is based on year-over-year commercial aviation revenue growth at CMC beginning in 2014. Imputed interest on the advances was 4.61% at October 25, 2013.

Pension and Other Post-Retirement Benefit Obligations

Our pension plans principally include a U.S. pension plan maintained by Esterline and non-U.S. plans maintained by CMC. Our principal post-retirement plans include non-U.S. plans maintained by CMC, which are non-contributory health care and life insurance plans.

We account for pension expense using the end of the fiscal year as our measurement date, and we make actuarially computed contributions to our pension plans as necessary to adequately fund benefits. Our funding policy is consistent with the minimum funding requirements of ERISA. In fiscal 2013 and 2012, operating cash flow included $27.0 million and $27.3 million, respectively, of cash funding to these pension plans. We expect pension funding requirements for the plans maintained by Esterline and CMC to be approximately $12.0 million and $10.6 million, respectively, in fiscal 2014. The rate of increase in future compensation levels is consistent with our historical experience and salary administration policies. The expected long-term rate of return on plan assets is based on long-term target asset allocations of 70% equity and 30% fixed income. We periodically review allocations of plan assets by investment type and evaluate external sources of information regarding long-term historical returns and expected future returns for each investment type, and accordingly, believe a 6.34% to 7.0% assumed long-term rate of return on plan assets is appropriate for both the Esterline and CMC plans. Current allocations are consistent with the long-term targets.

We made the following assumptions with respect to our Esterline pension obligation in fiscal 2013 and 2012:

We made the following assumptions with respect to our CMC pension obligation in fiscal 2013 and 2012:

33

We use a discount rate for expected returns that is a spot rate developed from a yield curve established from high-quality corporate bonds and matched to plan-specific projected benefit payments. Although future changes to the discount rate are unknown, had the discount rate increased or decreased by 25 basis points in fiscal 2013, pension liabilities in total would have decreased $11.8 million or increased $12.3 million, respectively. If all other assumptions are held constant, the estimated effect on fiscal 2013 pension expense from a hypothetical 25 basis points increase or decrease in both the discount rate and expected long-term rate of return on plan assets would not have a material effect on our pension expense.

We made the following assumptions with respect to our Esterline post-retirement obligation in fiscal 2013 and 2012:

We made the following assumptions with respect to our CMC post-retirement obligation in fiscal 2013 and 2012:

The assumed health care trend rate has a significant impact on our post-retirement benefit obligations. Our health care trend rate was based on the experience of our plan and expectations for the future. A 100 basis points increase in the health care trend rate would increase our post-retirement benefit obligation by $1.9 million at October 25, 2013. A 100 basis points decrease in the health care trend rate would decrease our post-retirement benefit obligation by $0.5 million at October 25, 2013. Assuming all other assumptions are held constant, the estimated effect on fiscal 2013 post-retirement benefit expense from a hypothetical 100 basis points increase or decrease in the health care trend rate would not have a material effect on our post-retirement benefit expense.

Research and Development Expense

For the three years ended October 25, 2013, research and development expense has averaged 5.2% of sales. We estimate that research and development expense in fiscal 2014 will be about 5% of sales for the full year.

Contractual Obligations

The following table summarizes our outstanding contractual obligations as of fiscal year end. Liabilities for income taxes were excluded from the table, as we are not able to make a reasonably reliable estimate of the amount and period of related future payments.

In Thousands

Seasonality

The timing of our revenues is impacted by the purchasing patterns of our customers and, as a result, we do not generate revenues evenly throughout the year. Moreover, our first fiscal quarter, November through January, includes significant holiday vacation periods in both Europe and North America. This leads to decreased order and shipment activity; consequently, first quarter results are typically weaker than other quarters and not necessarily indicative of our performance in subsequent quarters.

Disclosures About Market Risk

Interest Rate Risks

Our debt includes fixed rate and variable rate obligations at October 25, 2013. We are not subject to interest rate risk on the fixed rate obligations. We are subject to interest rate risk on the Euro Term Loan, U.S. Term Loan, and U.S. credit facility. For long-term debt, the table presents principal cash flows and the related weighted-average interest rates by contractual maturities.

A hypothetical 10% increase or decrease in average market rates would not have a material effect on our pretax income.

Currency Risks

We own significant operations in Canada, France and the United Kingdom. To the extent that sales are transacted in a foreign currency, we are subject to foreign currency fluctuation risk. Furthermore, we have assets denominated in foreign currencies that are not offset by liabilities in such foreign currencies. At October 25, 2013, we had the following monetary assets subject to foreign currency fluctuation risk: U.S. dollar-denominated backlog with customers whose functional currency is other than the U.S. dollar; U.S. dollar-denominated accounts receivable and payable; and certain forward contracts, which are not accounted for as a cash flow hedge. The foreign exchange rate for the dollar relative to the euro decreased to 0.724 at October 25, 2013, from 0.773 at October 26, 2012; the dollar relative to the U.K. pound decreased to 0.619 from 0.621; and the dollar relative to the Canadian dollar increased to 1.045 from 0.997. Foreign currency transactions affecting monetary assets and forward contracts resulted in a $1.7 million loss in fiscal 2013, a $3.5 million loss in fiscal 2012, and a $13.8 million gain in fiscal 2011. The $13.8 million gain in fiscal 2011 included a $6.3 million gain due to our holding euros to fund the Souriau acquisition.

Our policy is to hedge a portion of our forecasted transactions using forward exchange contracts with maturities up to 45 months. The Company does not enter into any forward contracts for trading purposes. At October 25, 2013, and October 26, 2012, the notional value of foreign currency forward contracts was $373.2 million and $359.3 million, respectively. The net fair value of these contracts was a $1.3 million asset and a $2.5 million asset at October 25, 2013, and October 26, 2012, respectively. If the U.S. dollar increased by a hypothetical 5%, the effect on the fair value of the foreign currency contracts would be an increase of $17.9 million. If the U.S. dollar decreased by a hypothetical 5%, the effect on the fair value of the foreign currency contracts would be a decrease of $19.8 million.

The following tables provide information about our significant derivative financial instruments, including foreign currency forward exchange agreements and certain firmly committed sales transactions denominated in currencies other than the functional currency at October 25, 2013, and October 26, 2012. The information about certain firmly committed sales contracts and derivative financial instruments is in U.S. dollar equivalents. For forward foreign currency exchange agreements, the following tables present the notional amounts at the current exchange rate and weighted-average contractual foreign currency exchange rates by contractual maturity dates.

Critical Accounting Policies

Our financial statements and accompanying notes are prepared in accordance with U.S. generally accepted accounting principles. Preparing financial statements requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses. Actual results may differ from estimates under different assumptions or conditions. These estimates and assumptions are affected by our application of accounting policies. Our critical accounting policies include revenue recognition, accounting for the allowance for doubtful accounts receivable, accounting for inventories, impairment of goodwill and intangible assets, impairment of long-lived assets, accounting for legal contingencies, accounting for pension benefits, and accounting for income taxes.

Revenue Recognition

We recognize revenue when the title and risk of loss have passed to the customer, there is persuasive evidence of an agreement, delivery has occurred or services have been rendered, the price is determinable, and the collectability is reasonably assured. We recognize product revenues at the point of shipment or delivery in accordance with the terms of sale. Sales are net of returns and allowances. Returns and allowances are not significant because products are manufactured to customer specification and are covered by the terms of the product warranty.

Revenues and profits on fixed-price contracts with significant engineering as well as production requirements are recorded based on the achievement of contractual milestones and the ratio of total actual incurred costs to date to total estimated

38

costs for each contract (cost-to-cost method). We review cost performance and estimates to complete on our ongoing contracts at least quarterly. The impact of revisions of profit estimates are recognized on a cumulative catch-up basis in the period in which the revisions are made. Provisions for anticipated losses on contracts are recorded in the period they become evident. When change orders have been approved by both the company and the customer for both scope and price and realization is deemed probable, the original contract price is adjusted and revenues are recognized on contract performance (as determined by the achievement of contractual milestones and the cost-to-cost method). For partially approved change orders, costs attributable to unpriced change orders are treated as costs of the contract performance in the period the costs are incurred. Claims are also recognized as contract revenue when approved by both the company and the customer, based on contract performance.

Allowance for Doubtful Accounts

We establish an allowance for doubtful accounts for losses expected to be incurred on accounts receivable balances. Judgment is required in estimation of the allowance and is based upon specific identification, collection history and creditworthiness of the debtor.

Inventories

We account for inventories on a first-in, first-out or average cost method of accounting at the lower of its cost or market. The determination of market requires judgment in estimating future demand, selling prices and cost of disposal. Judgment is required when determining inventory cost adjustments. Inventory cost adjustments are recorded when inventory is considered to be excess or obsolete based upon an analysis of actual on-hand quantities on a part-level basis to forecasted product demand and historical usage.

Impairment of Goodwill and Intangible Assets

Goodwill and indefinite-lived intangible assets are required to be tested for impairment at least annually. We are also required to test goodwill for impairment between annual tests if events occur or circumstances change that would more likely than not reduce our enterprise fair value below its book value. These events or circumstances could include a significant change in the business climate, including a significant sustained decline in an entity’s market value, legal factors, operating performance indicators, competition, sale or disposition of a significant portion of the business, or other factors.

Goodwill is tested for impairment in a two-step process. The first step (Step One) of the goodwill impairment test involves estimating the fair value of a reporting unit. Fair value (Fair Value) is defined as “the amount at which an asset (or liability) could be bought (or incurred) or sold (or settled) in a current transaction between willing parties, that is, other than in a forced liquidation sale.” A reporting unit is generally defined at the operating segment level or at the component level one level below the operating segment, if said component constitutes a business. The Fair Value of a reporting unit is then compared to its carrying value, which is defined as the book basis of total assets less total liabilities. In the event a reporting unit’s carrying value exceeds its estimated Fair Value, evidence of potential impairment exists. In such a case, the second step (Step Two) of the impairment test is required, which involves allocating the Fair Value of the reporting unit to all of the assets and liabilities of that unit, with the excess of Fair Value over allocated net assets representing the Fair Value of goodwill. An impairment loss is measured as the amount by which the carrying value of the reporting unit’s goodwill exceeds the estimated Fair Value of goodwill.

As we have grown through acquisitions, we have accumulated $1.1 billion of goodwill and $47.2 million of indefinite-lived intangible assets out of total assets of $3.3 billion at October 25, 2013. The amount of any annual or interim impairment could be significant and could have a material adverse effect on our reported financial results for the period in which the charge is taken. During the third fiscal quarter of 2013, management performed a Step One impairment test for Racal Acoustics, Inc. (Racal Acoustics) upon identification of an indicator of impairment. The Company’s third quarter forecast in 2013 projected a higher operating loss in fiscal 2013 and lower earnings over the five years compared to the prior-year forecast due to further delays and reductions in global defense programs. As required under U.S. GAAP, a Step Two impairment test was required in fiscal 2013, because the current fair value of the business using a discounted cash flow and market approach was less than its carrying amount of the business. Under Step Two, the fair value of all Racal Acoustics’ assets and liabilities were estimated, including tangible assets, existing technology, and trade names, for the purpose of deriving an estimate of the implied fair value of goodwill. The implied fair value of the goodwill was then compared to the recorded goodwill to determine the amount of the impairment. Assumptions used in measuring the value of these assets and liabilities included the discount rates, royalty rates, and obsolescence rates used in valuing the intangible assets and pricing of comparable transactions in the market in valuing the tangible assets. The excess of the carrying amount of goodwill over the implied fair value of goodwill resulted in an impairment charge of $3.5 million in fiscal 2013. An impairment charge of $52.2 million was recorded at Racal Acoustics in fiscal 2012.

39

We performed our annual impairment review for fiscal 2013 as of July 27, 2013, and our Step One analysis indicates that no impairment of goodwill or other indefinite-lived assets exists at any of our other reporting units. Our Souriau reporting unit’s margin in passing the Step One analysis was about 12%, mainly reflecting lower market valuation assumptions in 2013. Management expects that continued improvements in operations will result in favorable actual results compared to our original plan. It is possible, however, that as a result of events or circumstances, we could conclude at a later date that goodwill of $347.6 million at Souriau may be considered impaired. We also may be required to record an earnings charge or incur unanticipated expenses if, due to a change in strategy or other reasons, we determined the value of other assets has been impaired. These other assets include trade names of $33.7 million and intangible assets of $181.7 million.

The valuation of reporting units requires judgment in estimating future cash flows, discount rates and estimated product life cycles. In making these judgments, we evaluate the financial health of the business, including such factors as industry performance, changes in technology and operating cash flows.

We used available market data and a discounted cash flow analysis in completing our 2013 annual impairment test. We believe that our cash flow estimates are reasonable based upon the historical cash flows and future operating and strategic plans of our reporting units. In addition to cash flow estimates, our valuations are sensitive to the rate used to discount cash flows and future growth assumptions. Except for Souriau, the fair value of all our reporting units exceeds its book value by greater than 20%. A 0.5% change in the discount rate used in the cash flow analysis would result in a change in the fair value of our other reporting units of approximately $83.6 million. A 0.5% change in the growth rate assumed in the calculation of the terminal value of cash flows would result in a change in the fair value of our other reporting units by $53.4 million. None of these changes would have resulted in any of our other reporting units to be impaired.

Impairment of Long-lived Assets

Long-lived assets that are to be disposed of are required to be reported at the lower of its carrying amount or fair value less cost to sell. An asset (other than goodwill and indefinite-lived intangible assets) is considered impaired when estimated future cash flows are less than the carrying amount of the asset. The first step (Step One) of an impairment test of long-lived assets is to determine the amount of future undiscounted cash flow of the long-lived asset. In the event the undiscounted future cash flow is less than the carrying amount of the long-lived asset, a second step is required (Step Two), and the long-lived asset is adjusted to its estimated fair value. Fair value is generally determined based upon estimated discounted future cash flows.

As we have grown through acquisitions, we have accumulated $533.8 million of definite-lived intangible assets. The amount of any annual or interim impairment could be significant and could have a material adverse effect on our reported financial results for the period in which the charge is taken.

Contingencies

We are party to various lawsuits and claims, both as plaintiff and defendant, and have contingent liabilities arising from the conduct of business. We are covered by insurance for general liability, product liability, workers’ compensation and certain environmental exposures, subject to certain deductible limits. We are self-insured for amounts less than our deductible and where no insurance is available. An estimated loss from a contingency should be accrued by a charge to income if it is probable that an asset has been impaired or a liability has been incurred and the amount of the loss can be reasonably estimated. Disclosure of a contingency is required if there is at least a reasonable possibility that a loss has been incurred. We evaluate, among other factors, the degree of probability of an unfavorable outcome and the ability to make a reasonable estimate of the amount of loss.

Pension and Other Post-Retirement Benefits

We account for pension expense using the end of the fiscal year as our measurement date. We select appropriate assumptions including discount rate, rate of increase in future compensation levels and assumed long-term rate of return on plan assets and expected annual increases in costs of medical and other health care benefits in regard to our post-retirement benefit obligations. Our assumptions are based upon historical results, the current economic environment and reasonable expectations of future events. Actual results which vary from our assumptions are accumulated and amortized over future periods, and accordingly, are recognized in expense in these periods. Significant differences between our assumptions and actual experience or significant changes in assumptions could impact the pension costs and the pension obligation.

Income Taxes

The objectives of accounting for income taxes are to recognize the amount of taxes payable or refundable for the current year and deferred tax liabilities and assets for the future tax consequences of events that have been recognized in our financial statements or tax returns. Judgment is required in assessing the future tax consequences of events that have been recognized in our financial statements or tax returns. Variations in the actual outcome of these future tax consequences could materially impact our financial position and results of operations.
