Most of our products generate significant aftermarket revenue. Once our parts are designed into and sold on a new aircraft, we generate net sales from aftermarket consumption over the life of that aircraft, which is generally estimated to be approximately 3025-30 years. A typical platform can be produced for 20 to 30 years, giving us an estimated product life cycle in excess of ~~50-60~~50 years. We estimate that approximately ~~53%~~55% of our net sales in fiscal year ~~2013~~2014 were generated from aftermarket sales, the vast majority of which come from the commercial and military aftermarkets. These aftermarket revenues have historically produced a higher gross margin and been more stable than sales to original equipment manufacturers, or OEMs.

We primarily design, produce and supply highly-engineered proprietary aerospace components (and certain systems/subsystems) with significant aftermarket content. We seek to develop highly customized products to solve specific needs for aircraft operators and manufacturers. We attempt to differentiate ourselves based on

engineering, service and manufacturing capabilities. We typically choose not to compete for non-proprietary “build to print” business because it frequently offers lower margins than proprietary products. We believe that our products have strong brand names within the industry and that we have a reputation for high quality, reliability and customer support.

Our business is well diversified due to the broad range of products that we offer to our customers. Some of our more significant product offerings, substantially all of which are ultimately provided to end-users in the aerospace industry, include mechanical/electro-mechanical actuators and controls, ignition systems and engine technology, specialized pumps and valves, power conditioning devices, specialized AC/DC electric motors and generators, NiCad batteries and chargers, engineered latching and locking devices, rods and locking devices, engineered connectors and elastomers, cockpit security components and systems, specialized cockpit displays, aircraft audio systems, specialized lavatory components, seatbelts and safety restraints, engineered interior surfaces, ~~and~~ lighting and control ~~technology.~~technology and military personnel parachutes and cargo delivery systems.

During TransDigm’s third quarter ended June 29, 2013, the Company changed its internal management structure and its reporting structure of financial information used to assess performance and allocate resources. The Company’s businesses are organized and managed in three reporting segments: Power & Control, Airframe and Non-aviation.

The Power & Control segment includes operations that primarily develop, produce and market systems and components that predominately provide power to or control power of the aircraft utilizing electronic, fluid, power and mechanical motion control technologies. Major product offerings include mechanical/electro-mechanical actuators and controls, ignition systems and engine technology, specialized pumps and valves, power conditioning devices and specialized AC/DC electric motors and generators. Primary customers of this segment are engine and power system and subsystem suppliers, airlines, third party maintenance suppliers, military buying agencies and repair depots. Products are sold in the original equipment and aftermarket market channels.

The Airframe segment includes operations that primarily develop, produce and market systems and components that are used in non-power airframe applications utilizing airframe and cabin structure technologies. Major product offerings include engineered latching and locking devices, rods and locking devices, engineered connectors and elastomers, cockpit security components and systems, aircraft audio systems, specialized lavatory components, seatbelts and safety restraints, engineered interior surfaces, ~~and~~ lighting and control ~~technology.~~technology, military personnel parachutes and cargo aerial delivery systems. Primary customers of this segment are airframe manufacturers and cabin system suppliers and subsystem suppliers, airlines, third party maintenance suppliers, military buying agencies and repair depots. Products are sold in the original equipment and aftermarket market channels.

The Non-aviation segment includes operations that primarily develop, produce and market products for non-aviation markets. Major product offerings include seatbelts and safety restraints for ground transportation applications, mechanical/electro-mechanical actuators and controls for space applications, and refueling systems for heavy equipment used in mining, construction and other industries. Primary customers of this segment are off road vehicle suppliers and subsystem suppliers, child restraint system suppliers, satellite and space system suppliers and manufacturers of heavy equipment used in mining, construction and other industries.

For financial information about our segments, see Note 16, “Segments” to our Consolidated Financial Statements.

Consistent with our overall strategy, our sales and marketing organization is structured to continually develop technical solutions that meet customer needs. In particular, we attempt to focus on products and programs that will lead to high-margin, repeatable sales in the aftermarket.

We have structured our sales efforts along our major product offerings, assigning a product manager to certain products. Each product manager is expected to grow the sales and profitability of the products for which he or she is responsible and to achieve the targeted annual level of bookings, sales, new business and profitability for such products. The product managers are assisted by account managers and sales engineers who are responsible for covering major OEM and aftermarket accounts. Account managers and sales engineers are expected to be familiar with the personnel, organization and needs of specific customers to achieve total bookings and new business goals at each account and, together with the product managers, to determine when additional resources are required at customer locations. Most of our sales personnel are evaluated, in part, on their bookings and their ability to identify and obtain new business opportunities.

Though typically performed by employees, the account manager function may be performed by independent representatives depending on the specific customer, product and geographic location. We also use a number of distributors to provide logistical support as well as primary customer contact with certain smaller accounts. Our major distributors are Aviall, Inc. (a subsidiary of The Boeing Company) and Satair A/S (a subsidiary of ~~Airbus)~~Airbus S.A.S.).

We maintain 3842 principal manufacturing facilities. Most of our manufacturing facilities are comprised of manufacturing, distribution and engineering functions, and most facilities have certain administrative functions, including management, sales and finance. We continually strive to improve productivity and reduce costs, including rationalization of operations, developing improved control systems that allow for accurate product profit and loss accounting, investing in equipment, tooling, information systems and implementing broad-based employee training programs. Management believes that our manufacturing systems and equipment contribute to our ability to compete by permitting us to meet the rigorous tolerances and cost sensitive price structure of aircraft component customers.

We attempt to differentiate ourselves from our competitors by producing uniquely engineered products with high quality and timely delivery. Our engineering costs are recorded in Cost of Sales and in Selling and Administrative Expenses ~~captions~~ in our Consolidated Statements of Income. Total engineering expense represents approximately 6%7% of our operating units’ aggregate costs, or approximately 3%4% of our consolidated net sales. Our proprietary products, and particularly our new product initiatives, are designed by our engineers and are intended to serve the needs of the aircraft component industry. These proprietary designs must withstand the extraordinary conditions and stresses that will be endured by products during use and meet the rigorous demands of our customers’ tolerance and quality requirements.

We use sophisticated equipment and procedures to comply with quality requirements, specifications and Federal Aviation Administration ~~(the “FAA”~~(“FAA”) and OEM requirements. We perform a variety of testing procedures, including testing under different temperature, humidity and altitude levels, shock and vibration testing and X-ray fluorescent measurement. These procedures, together with other customer approved techniques for document, process and quality control, are used throughout our manufacturing facilities.

Our customers include: (1) distributors of aerospace components; (2) worldwide commercial airlines, including national and regional airlines; (3) large commercial transport and regional and business aircraft OEMs; (4) various armed forces of the United States and friendly foreign governments; (5) defense OEMs; (6) system suppliers; and (7) various other industrial customers. For the year ended September 30, ~~2013,~~2014, Boeing (which includes Aviall, Inc., a distributor of commercial aftermarket parts to airlines throughout the world) accounted for approximately ~~12%~~13% of our net sales. Our top ten customers for fiscal year ~~2013~~2014 accounted for approximately ~~41%~~43% of our net sales. Products supplied to many of our customers are used on multiple platforms.

Active commercial production programs include the Boeing 737, 747, 767, 777 and 787, the Airbus A319/20/21, A330/A340, A350 and A380, the Bombardier CRJ’s, Challenger and Learjets, the Embraer RJ’s, the

Cessna Citation family, the Raytheon Premier and Hawker and most Gulfstream airframes. Military platforms

include aircraft such as the Boeing C-17, F-15, F-18 and V-22, the Airbus A400M, the Lockheed Martin C-130J, F-16 and F-35 Joint Strikefighter, the Northrop Grumman E-2C Hawkeye, the Sikorsky UH-60 helicopter,CH-47 Chinook and AH-64 Apache helicopters, the General Atomics Predator Drone and the Raytheon Patriot Missile. TransDigm has been awarded numerous contracts for the development of engineered products for production on the Airbus ~~A350XWB and~~ A320 NEO, the ~~Bombardier Learjet 85,~~Boeing 737 MAX, the Sikorsky S-97, JMR helicopter and Boeing P-8 Poseidon.

The demand for our aftermarket parts and services depends on, among other things, the breadth of our installed OEM base, revenue passenger miles (“RPMs”), the size and age of the worldwide aircraft fleet and, to a lesser extent, airline profitability. We believe that we are also a leading supplier of components used on U.S. designed military aircraft, including components that are used on a variety of fighter aircraft, military freighters and military helicopters.

The niche markets within the aerospace industry that we serve are relatively fragmented and we face several competitors for many of the products and services we provide. Due to the global nature of the commercial aircraft industry, competition in these categories comes from both U.S. and foreign companies. Competitors in our product offerings range in size from divisions of large public corporations to small privately-held entities, with only one or two components in their entire product portfolios.

We compete on the basis of engineering, manufacturing and marketing high quality products, which we believe meet or exceed the performance and maintenance requirements of our customers, consistent and timely delivery, and superior customer service and support. The industry’s stringent regulatory, certification and technical requirements, and the investments necessary in the development and certification of products, create barriers to entry for potential new competitors. As long as customers receive products that meet or exceed expectations and performance standards, we believe that they will have a reduced incentive to certify another supplier because of the cost and time of the technical design and testing certification process. In addition, we believe that the availability, dependability and safety of our products are reasons for our customers to continue long-term supplier relationships.

Companies engaged in supplying defense-related equipment and services to U.S. Government agencies are subject to business risks specific to the defense industry. These risks include the ability of the U.S. Government to unilaterally: (1) suspend us from receiving new contracts pending resolution of alleged violations of procurement laws or regulations; (2) terminate existing contracts; (3) reduce the value of existing contracts; (4) audit our contract-related costs and fees, including allocated indirect costs; and (5) control and potentially prohibit the export of our products.

The commercial aircraft component industry is highly regulated by ~~both~~ the FAA in the United States and by the Joint Aviation Authorities in Europe and other agencies throughout the world, while the military aircraft component industry is governed by military quality specifications. We, and the components we manufacture, are required to be certified by one or more of these entities or agencies, and, in many cases, by individual OEMs, in order to engineer and service parts and components used in specific aircraft models.

We must also satisfy the requirements of our customers, including OEMs and airlines that are subject to FAA regulations, and provide these customers with products and services that comply with the government regulations applicable to commercial flight operations. In addition, the FAA requires that various maintenance

routines be performed on aircraft components. We believe that we currently satisfy or exceed these maintenance standards in our repair and overhaul services. We also maintain several FAA approved repair stations.

In addition, sales of many of our products that will be used on aircraft owned by non-U.S. entities are subject to compliance with U.S. export control laws.

Our operations are also subject to a variety of worker and community safety laws. The Occupational Safety and Health Act (“OSHA”), mandates general requirements for safe workplaces for all employees. In addition, OSHA provides special procedures and measures for the handling of certain hazardous and toxic substances.

We require the use of various raw materials in our manufacturing processes. We also purchase a variety of manufactured component parts from various suppliers. At times, we concentrate our orders among a few suppliers in order to strengthen our supplier relationships. ~~Raw~~Most of our raw materials and component parts are generally available from multiple suppliers at competitive prices.

We have various trade secrets, proprietary information, trademarks, trade names, patents, copyrights and other intellectual property rights, which we believe, in the aggregate but not individually, are important to our business.

As of September 30, ~~2013,~~2014, the Company estimated its sales order backlog at ~~$1,081~~$1,195 million compared to an estimated sales order backlog of ~~$833~~$1,081 million as of September 30, ~~2012.~~2013. The increase in estimated sales order backlog of approximately $114 million is primarily due to ~~acquisitions discussed below, totaling approximately $202 million and an increase in orders across existing OEM product lines and to a lesser extent the aftermarket.~~acquisitions. The majority of the purchase orders outstanding as of September 30, ~~2013~~2014 are scheduled for delivery within the next twelve months. Purchase orders may be subject to cancellation or deferral by the customer prior to shipment. The level of unfilled purchase orders at any given date during the year will be materially affected by the timing of the Company’s receipt of purchase orders and the speed with which those orders are filled. Accordingly, the Company’s backlog as of September 30, ~~2013~~2014 may not necessarily represent the actual amount of shipments or sales for any future period.

Although we manufacture a significant portion of our products in the United States, we manufacture some products in Belgium, China, Malaysia, Mexico, Sri Lanka and the United Kingdom. ~~We sell our products in the United States, as well as in foreign countries.~~ Although the majority of sales of our products are made to customers ~~including distributors~~(including distributors) located in the United States, our products are ultimately sold to and used by customers ~~including~~(including airlines and other end users of ~~aircraft,~~aircraft) throughout the world. A number of risks inherent in international operations could have a material adverse effect on our results of operations, including currency fluctuations, difficulties in staffing and managing multi-national operations, general economic and political uncertainties and potential for social unrest in countries in which we operate, limitations on our ability to enforce legal rights and remedies, restrictions on the repatriation of funds, change in trade policies, tariff regulation, difficulties in obtaining export and import licenses and the risk of government financed competition.

Our direct sales to foreign customers were approximately $735.9 million, $572.0 million, ~~$508.8 million,~~ and ~~$305.5~~$508.8 million for fiscal years 2014, 2013 ~~2012~~ and ~~2011,~~2012, respectively. Sales to foreign customers are subject to numerous additional risks, including the impact of foreign government regulations, political uncertainties and differences in business practices. There can be no assurance that foreign governments will not adopt regulations or take other action that would have a direct or indirect adverse impact on the business or market opportunities of the Company within such governments’ countries. Furthermore, there can be no assurance that the political, cultural and economic climate outside the United States will be favorable to our operations and growth strategy.

Our operations and facilities are subject to a number of federal, state, local and foreign environmental laws and regulations that govern, among other things, discharges of pollutants into the air and water, the generation, handling, storage and disposal of hazardous materials and wastes, the remediation of contamination and the health and safety of our employees. Environmental laws and regulations may require that the Company investigate and remediate the effects of the release or disposal of materials at sites associated with past and present operations. Certain facilities and third-party sites utilized by subsidiaries of the Company have been identified as potentially responsible parties under the federal Superfund laws and comparable state laws. The Company is currently involved in the investigation and remediation of a number of sites under applicable laws.

Estimates of the Company’s environmental liabilities are based on current facts, laws, regulations and technology. These estimates take into consideration the Company’s prior experience and professional judgment of the Company’s environmental advisors. Estimates of the Company’s environmental liabilities are further subject to uncertainties regarding the nature and extent of site contamination, the range of remediation alternatives available, evolving remediation standards, imprecise engineering evaluations and cost estimates, the extent of corrective actions that may be required and the number and financial condition of other potentially responsible parties, as well as the extent of their responsibility for the remediation.

Accordingly, as investigation and remediation proceed, it is likely that adjustments in the Company’s accruals will be necessary to reflect new information. The amounts of any such adjustments could have a material adverse effect on the Company’s results of operations or cash flows in a given period. Based on currently available information, however, the Company does not believe that future environmental costs in excess of those accrued with respect to sites for which the Company has been identified as a potentially responsible party are likely to have a material adverse effect on the Company’s financial condition.

Environmental liabilities are recorded when the liability is probable and the costs are reasonably estimable, which generally is not later than at completion of a feasibility study or when the Company has recommended a remedy or has committed to an appropriate plan of action. The liabilities are reviewed periodically and, as investigation and remediation proceed, adjustments are made as necessary. Liabilities for losses from environmental remediation obligations do not consider the effects of inflation and anticipated expenditures are not discounted to their present value. The liabilities are not reduced by possible recoveries from insurance carriers or other third parties, but do reflect anticipated allocations among potentially responsible parties at federal Superfund sites or similar state-managed sites, third party indemnity obligations, and an assessment of the likelihood that such parties will fulfill their obligations at such sites.

We are from time to time subject to, and are presently involved in, litigation or other legal proceedings arising in the ordinary course of business. Based upon information currently known to us, we believe the outcome of such proceedings will not have, individually or in the aggregate, a material adverse effect on our business, our financial condition or results of operations.

TD Group’s Annual Report on Form 10-K, Quarterly Reports on Form 10-Q and Current Reports on Form 8-K, including any amendments, will be made available free of charge on the Company’s website,www.transdigm.com, as soon as reasonably practicable, following the filing of the reports with the Securities and Exchange Commission.

Set forth below are important risks and uncertainties that could negatively affect our business and financial condition and could cause our actual results to differ materially from those expressed in forward-looking statements contained in this report.

Our business is sensitive to the number of flight hours that our customers’ planes spend aloft, the size and age of the worldwide aircraft fleet and our customers’ profitability. These items are, in turn, affected by general economic and geopolitical and other worldwide conditions.

Our business is directly affected by, among other factors, changes in revenue passenger miles (RPMs), the size and age of the worldwide aircraft fleet and, to a lesser extent, changes in the profitability of the commercial airline industry. RPMs and airline profitability have historically been correlated with the general economic environment, although national and international events also play a key role. For example, in the recent past, the airline industry has been severely affected by the downturn in the global economy, higher fuel prices, the increased security concerns among airline customers following the events of September 11, 2001, the Severe Acute Respiratory Syndrome, or SARS, epidemic and the conflicts in Afghanistan and ~~Iraq.~~Iraq, and could be impacted by future geopolitical or other worldwide conditions, such as war, terrorist acts, or a worldwide infectious disease outbreak. In addition, global market and economic conditions have been challenging with continued turbulence in the U.S. and international markets and economies and have prolonged declines in business and consumer spending. As a result of the substantial reduction in airline traffic resulting from these events, the airline industry incurred large losses and financial difficulties. Some carriers have also parked or retired a portion of their fleets and have reduced workforces and flights. During periods of reduced airline profitability, some airlines may delay purchases of spare parts, preferring instead to deplete existing inventories. If demand for new aircraft and spare parts decreases, there would be a decrease in demand for certain of our products.

Our sales to manufacturers of aircraft are cyclical, and a downturn in sales to these manufacturers may adversely affect us.

Our sales to manufacturers of large commercial aircraft, such as The Boeing Company, Airbus S.A.S, and related OEM suppliers, as well as manufacturers of business jets ~~which~~(which accounted for approximately ~~27%~~26% of our net sales in fiscal year ~~2013,~~2014) have historically experienced periodic downturns. In the past, these sales have been affected by airline profitability, which is impacted by, among other things, fuel and labor costs, price competition, downturns in the global economy and national and international events, such as the events of September 11, 2001. In addition, sales of our products to manufacturers of business jets are impacted by, among other things, downturns in the global economy. Downturns adversely affect our net sales, gross margin and net income.

Our largest customer for fiscal year ~~2013~~2014 was The Boeing Company (which includes Aviall, Inc., a distributor of commercial aftermarket parts to airlines throughout the world). Boeing accounted for approximately ~~12%~~13% of our net sales in fiscal year ~~2013.~~2014. Our top ten customers for fiscal year ~~2013~~2014 accounted for

approximately ~~41%~~43% of our net sales. A material reduction in purchasing by one of our larger customers for any reason, including but not limited to economic downturn, decreased production, strike or resourcing, could have a material adverse effect on our net sales, gross margin and net income.

We generally do not have guaranteed future sales of our products. Further, when we enter into fixed price contracts with some of our customers, we take the risk for cost overruns.

As is customary in our business, we do not generally have long-term contracts with most of our aftermarket customers and, therefore, do not have guaranteed future sales. Although we have long-term contracts with many of our OEM customers, many of those customers may terminate the contracts on short notice and, in most cases,

our customers have not committed to buy any minimum quantity of our products. In addition, in certain cases, we must anticipate the future volume of orders based upon the historic purchasing patterns of customers and upon our discussions with customers as to their anticipated future requirements, and this anticipated future volume of orders may not materialize.

We also have entered into multi-year, fixed-price contracts with some of our customers, pursuant to which we have agreed to perform the work for a fixed price and, accordingly, realize all the benefit or detriment resulting from any decreases or increases in the costs of making these products. Sometimes we accept a fixed-price contract for a product that we have not yet produced, and this increases the risk of cost overruns or delays in the completion of the design and manufacturing of the product. Most of our contracts do not permit us to recover increases in raw material prices, taxes or labor costs.

The military and defense market is significantly dependent upon government budget trends, particularly the U.S. Department of Defense (the “DOD”) budget. In addition to normal business risks, our supply of products to the United States Government is subject to unique risks largely beyond our control. DOD budgets could be negatively impacted by several factors, including, but not limited to, a change in defense spending policy by the current presidential administration, the U.S. Government’s budget deficits, spending priorities, the cost of sustaining the U.S. military presence in the Middle East and possible political pressure to reduce U.S. Government military spending, each of which could cause the DOD budget to remain unchanged or to decline. A significant decline in U.S. military expenditures could result in a reduction in the amount of our products sold to the various agencies and buying organizations of the U.S. Government.

We intend to pursue acquisitions. Our business may be adversely affected if we cannot consummate acquisitions on satisfactory terms, or if we cannot effectively integrate acquired operations.

A significant portion of our growth has occurred through acquisitions. Any future growth through acquisitions will be partially dependent upon the continued availability of suitable acquisition candidates at favorable prices and upon advantageous terms and conditions. We intend to pursue acquisitions that we believe will present opportunities consistent with our overall business strategy. However, we may not be able to find suitable acquisition candidates to purchase or may be unable to acquire desired businesses or assets on economically acceptable terms. In addition, we may not be able to raise the capital necessary to fund future acquisitions. Because we may actively pursue a number of opportunities simultaneously, we may encounter unforeseen expenses, complications and delays, including regulatory complications or difficulties in employing sufficient staff and maintaining operational and management oversight.

We regularly engage in discussions with respect to potential acquisition and investment opportunities. If we consummate an acquisition, our capitalization and results of operations may change significantly. Future acquisitions could result in margin dilution and further likely result in the incurrence of additional debt and contingent liabilities and an increase in interest and amortization expenses or periodic impairment charges related to goodwill and other intangible assets as well as significant charges relating to integration costs.

Acquisitions involve risks that the businesses acquired will not perform in accordance with expectations and that business judgments concerning the value, strengths and weaknesses of businesses acquired will prove incorrect. In addition, we may not be able to successfully integrate any business we acquire into our existing business. The successful integration of new businesses depends on our ability to manage these new businesses

and cut excess costs. The successful integration of future acquisitions may also require substantial attention from our senior management and the management of the acquired business, which could decrease the time that they have to service, attract customers and develop new products and services or attend to other acquisition opportunities.

We are subject to certain unique business risks as a result of supplying equipment and services to the U.S. Government.

Most of our U.S. Government contracts can be terminated by the U.S. Government for its convenience without significant notice. Termination for convenience provisions provide only for our recovery of costs incurred or committed, settlement expenses and profit on the work completed prior to termination.

On contracts for which the price is based on cost, the U.S. Government may review our costs and performance, as well as our accounting and general business practices. Based on the results of such audits, the U.S. Government may adjust our contract-related costs and fees, including allocated indirect costs. In addition, under U.S. Government purchasing regulations, some of our costs, including most financing costs, amortization of intangible assets, portions of research and development costs, and certain marketing expenses may not be subject to reimbursement.

In addition, even where the price is not based on cost, the U.S. Government may seek to review our costs to determine whether our pricing is “fair and reasonable”. Five of our subsidiaries and divisions were subject to such a pricing review for years 2002 through 2004 and it is possible that we will be subject to a similar pricing review in the future. Such a review could be costly and time consuming for our management and could distract from our ability to effectively manage the business. As a result of such a review, we could be subject to providing a refund to the U.S. Government or we could be asked to enter into an arrangement whereby our prices would be based on cost or the DOD could seek to pursue alternative sources of supply for our parts. Any of those occurrences could lead to a reduction in our revenue from, or the profitability of certain of our supply arrangements with, certain agencies and buying organizations of the U.S. Government.

Our business may be adversely affected if we would lose our government or industry approvals or if more stringent government regulations are enacted or if industry oversight is increased.

The aerospace industry is highly regulated in the United States and in other countries. In order to sell our components, we and the components we manufacture must be certified by the FAA, the DOD and similar agencies in foreign countries and by individual manufacturers. If new and more stringent government regulations are adopted or if industry oversight increases, we might incur significant expenses to comply with any new regulations or heightened industry oversight. In addition, if material authorizations or approvals were revoked or suspended, our business would be adversely affected.

In addition to the aviation approvals, we are at times required to obtain approval from U.S. Government agencies to export our products. Failure to obtain approval to export or determination by the U.S. Government

that we failed to receive required approvals or licenses could eliminate or restrict our ability to sell our products outside the United States, and the penalties that could be imposed by the U.S. Government for failure to comply with these laws could be significant.

Our substantial indebtedness could adversely affect our financial health and could harm our ability to react to changes to our business and prevent us from fulfilling our obligations under our indebtedness.

We have a significant amount of indebtedness. As of September 30, ~~2013,~~2014, our total indebtedness was approximately ~~$5,731.2~~$7,473.1 million, which was approximately ~~106.2%~~126.3% of our total capitalization because of our recent dividends funded with indebtedness.

In addition, we may be able to incur substantial additional indebtedness in the future. For example, as of September 30, ~~2013,~~2014, we had approximately ~~$303.2~~$413.2 million of unused commitments under our revolving loan ~~facility.~~facility and $25.0 million of unused capacity under our trade receivable securitization facility (the “Securitization Facility”) (with the availability of such capacity being dependent on the amount of our outstanding trade receivables). Although our senior secured credit facility and the indentures (the “Indentures”) governing ~~the 7~~³/₄~~% senior subordinated notes issued in December 2010 (the “2018 Notes”),~~ the 5¹/₂% senior subordinated notes issued in October 2012 (the “2020 Notes”), ~~and~~ the 7¹/₂% senior subordinated notes issued in July 2013 (the “2021 Notes”), the 6% senior subordinated notes issued in June 2014 (the “2022 Notes), and the 6¹/₂% senior subordinated notes issued June 2014 (the “2024 Notes” and together with the 2020 Notes, the 2021 Notes, the 2022 Notes, the “Notes”) contain restrictions on the incurrence of additional indebtedness, these restrictions are subject to a number of significant qualifications and exceptions, and the indebtedness incurred in compliance with these qualifications and exceptions could be substantial. If we incur additional debt, the risks associated with our substantial leverage would increase.

Our substantial ~~indebtedness~~debt could also have other important consequences to investors. For example, it could:

In addition, all of our debt under the senior secured credit facility, which includes a ~~$3.1~~$3.9 billion term loan facility and a revolving loan facility of ~~$310.0~~$420.0 million, bears interest at floating rates. Accordingly, in the event that interest rates increase, our debt service expense will also increase. In order to reduce the floating interest rate risk, as of September 30, ~~2013,~~2014, three forward starting interest rate swap agreements were in place fixing the rate of interest through June 30, 2015 on an aggregate notional amount of $353 million of debt under the senior secured credit facility. ~~In addition, in fiscal 2013, the Company entered into~~An additional three forward starting interest rate swap agreements were in place that fix the interest beginning September 30, 2014 on an aggregate notional amount of $1.0 billion of debt under the senior secured credit facility. In addition, in July 2014, we entered into five forward starting interest rate swap agreements that fix the interest beginning March 31, 2016 on an aggregate notional amount of $750 million of debt under the senior secured credit facility.

Our substantial level of indebtedness increases the possibility that we may be unable to generate cash sufficient to pay, when due, the principal of, interest on or other amounts due in respect of our indebtedness, including the ~~2018 Notes, 2020 Notes and the 2021~~ Notes. We cannot assure you that our business will generate sufficient cash flow from operations or that future borrowings will be available to us under the senior secured credit facility or otherwise in amounts sufficient to enable us to service our indebtedness. If we cannot service our debt, we will have to take actions such as reducing or delaying capital investments, selling assets, restructuring or refinancing our debt or seeking additional equity capital.

To service our indebtedness, we will require a significant amount of cash. Our ability to generate cash depends on many factors beyond our control and any failure to meet our debt service obligations could harm our business, financial condition and results of operations.

Our ability to make payments on and to refinance our indebtedness, including the ~~2018~~ Notes, ~~2020 Notes, 2021 Notes and~~ amounts borrowed under the credit facilities, amounts due under our Securitization Facility, and to fund our operations, will depend on our ability to generate cash in the future, which, to a certain extent, is subject to general economic, financial, competitive, legislative, regulatory and other factors that are beyond our control.

We cannot assure you that our business will generate sufficient cash flow from operations, that currently anticipated cost savings and operating improvements will be realized on schedule or at all or that future borrowings will be available to us under the senior secured credit facility or otherwise in amounts sufficient to enable us to service our indebtedness, including the amounts borrowed under the senior secured credit facility, amounts borrowed under our Securitization Facility and the ~~2018 Notes, 2020 Notes and the 2021~~ Notes, or to fund our other liquidity needs. If we cannot service our debt, we will have to take actions such as reducing or delaying capital investments, selling assets, restructuring or refinancing our debt or seeking additional equity capital. We cannot assure you that any of these remedies could, if necessary, be effected on commercially reasonable terms, or at all. Our ability to restructure or refinance our debt will depend on the condition of the capital markets and our financial condition at such time. Any refinancing of our debt could be at higher interest rates and may require us to comply with more onerous covenants, which could further restrict our business operations. The terms of existing or future debt instruments, the Indentures and the senior secured credit facility may restrict us from adopting any of these alternatives. In addition, any failure to make payments of interest and principal on our outstanding indebtedness on a timely basis would likely result in a reduction of our credit rating, which could harm our ability to incur additional indebtedness on acceptable terms and would otherwise adversely affect the ~~2018 Notes, 2020 Notes and the 2021~~ Notes.

The terms of the senior secured credit facility and Indentures may restrict our current and future operations, particularly our ability to respond to changes or to take certain actions.

Our senior secured credit facility and the Indentures contain a number of restrictive covenants that impose significant operating and financial restrictions on TD Group, TransDigm Inc. and its subsidiaries (in the case of the senior secured credit facility) and TransDigm Inc. and its subsidiaries (in the case of the Indentures) and may limit their ability to engage in acts that may be in our long-term best interests. The senior secured credit facility and Indentures include covenants restricting, among other things, the ability of TD Group, TransDigm Inc. and its subsidiaries (in the case of the senior secured credit facility) and TransDigm Inc. and its subsidiaries (in the case of the Indentures) to:

A breach of any of these covenants could result in a default under the senior secured credit facility or the Indentures. If any such default occurs, the lenders under the senior secured credit facility and the holders of the ~~2018 Notes, 2020 Notes and the 2021~~ Notes may elect to declare all outstanding borrowings, together with accrued interest and other amounts payable thereunder, to be immediately due and payable. The lenders under the senior secured credit facility also have the right in these circumstances to terminate any commitments they have to provide further borrowings. In addition, following an event of default under the senior secured credit facility, the lenders under that facility will have the right to proceed against the collateral granted to them to secure the debt, which includes our available cash, and they will also have the right to prevent us from making debt service payments on the ~~2018 Notes, 2020 Notes and the 2021~~ Notes. If the debt under the senior secured credit facility or the ~~2018 Notes, 2020 Notes and the 2021~~ Notes were to be accelerated, we cannot assure you that our assets would be sufficient to repay in full our debt.

We could incur substantial costs as a result of violations of or liabilities under environmental laws and regulations.

We are dependent on our highly trained employees and any work stoppage or difficulty hiring similar employees could adversely affect our business.

Because our products are complicated and highly engineered, we depend on an educated and trained workforce. There is substantial competition for skilled personnel in the aircraft component industry, and we could be adversely affected by a shortage of skilled employees. We may not be able to fill new positions or vacancies created by expansion or turnover or attract and retain qualified personnel.

As of September 30, ~~2013,~~2014, we had approximately ~~6,100~~7,300 full time, part time and temporary employees. Approximately ~~13%~~11% of our full time and part time employees were represented by labor unions. Collective bargaining agreements between us and these labor unions expire at various dates ranging from February ~~2014~~2015 to May 2018. We consider our relationship with our employees generally to be satisfactory. Although we believe that our relations with our employees are satisfactory, we cannot assure you that we will be able to negotiate a satisfactory renewal of these collective bargaining agreements or that our employee relations will remain stable. Because we maintain a relatively small inventory of finished goods, any work stoppage could materially and adversely affect our ability to provide products to our customers.

Our business is dependent on the availability of certain components and raw materials from suppliers.

Our business is affected by the price and availability of the raw materials and component parts that we use to manufacture our components. Our business, therefore, could be adversely impacted by factors affecting our suppliers (such as the destruction of our suppliers’ facilities or their distribution infrastructure, a work stoppage or strike by our suppliers’ employees or the failure of our suppliers to provide materials of the requisite quality), or by increased costs of such raw materials or components if we were unable to pass along such price increases to our customers. Because we maintain a relatively small inventory of raw materials and component parts, our business could be adversely affected if we were unable to obtain these raw materials and components from our suppliers in the quantities we require or on favorable terms. Although we believe in most cases that we could identify alternative suppliers, or alternative raw materials or component parts, the lengthy and expensive FAA and OEM certification processes associated with aerospace products could prevent efficient replacement of a supplier, raw material or component part.

Our facilities are located near known earthquake fault zones and hurricane paths, and the occurrence of a natural disaster could cause damage to our facilities and equipment, which could require us to curtail or cease operations.

A number of our manufacturing facilities are located in the greater Los Angeles area, an area known for earthquakes, and are thus vulnerable to damage. In addition, a number of our manufacturing facilities are located along the Eastern seaboard area susceptible to hurricanes. We are also vulnerable to damage from other types of disasters, including power loss, fire, explosions, floods, communications failures, terrorist attacks and similar events. If any disaster were to occur, our ability to operate our business at our facilities could be impaired.

WeThe Company’s subsidiaries which operate outside of the continental United States may be subject to additional risks.

A number of risks inherent in international operations could have ~~recorded~~ a ~~significant amount~~material adverse effect on our results of ~~intangible assets,~~operations, including currency fluctuations, difficulties in staffing and managing multi-national operations, general economic and political uncertainties and potential for social unrest in countries in which ~~may never generate~~we operate, limitations on our ability to enforce legal rights and remedies, restrictions on the ~~returns we expect.~~

~~Mergers~~repatriation of funds, change in trade policies, tariff regulation, difficulties in obtaining export and ~~acquisitions have resulted in significant increases in identifiable intangible assets~~import licenses and ~~goodwill. Identifiable intangible assets,~~the risk of government financed competition. Furthermore, the Company is subject to laws and regulations, such as the Foreign Corrupt Practices Act or similar local anti-bribery laws, which ~~primarily include trademarks, trade names, trade secrets,~~generally prohibit companies and ~~technology, were approximately $1,189.5 million at September 30, 2013, representing approximately 19% of our total assets. Goodwill recognized in accounting~~their employees, agents and contractors from making improper payments to governmental officials for the ~~mergers~~purpose of obtaining or retaining business. Failure to comply with these laws could subject the Company to civil and ~~acquisitions was approximately $3,343.9 million at September 30, 2013, representing approximately 54%~~criminal penalties that could materially adversely affect the Company’s results of our total assets. We may never realize the full value of our identifiable intangible assets and goodwill, and to the extent we were to determine that our identifiable intangible assets or our goodwill were impaired within the meaning of applicable accounting standards, we would be required to write-off the amount of any impairment.operations.

We operate in a highly competitive global industry and compete against a number of companies. Competitors in our product lines are both U.S. and foreign companies and range in size from divisions of large public corporations to small privately held entities. We believe that our ability to compete depends on high product performance, consistent high quality, short lead-time and timely delivery, competitive pricing, superior customer service and support and continued certification under customer quality requirements and assurance programs. We may have to adjust the prices of some of our products to stay competitive.

We could be adversely affected if one of our components causes an aircraft to crash.

Our operations expose us to potential liabilities for personal injury or death as a result of the failure of an aircraft component that we have designed, manufactured or serviced. While we maintain liability insurance to protect us from future products liability claims, in the event of product liability claims our insurers may attempt to deny coverage or any coverage we have may not be adequate. We also may not be able to maintain insurance coverage in the future at an acceptable cost. Any liability not covered by insurance or for which third party indemnification is not available could result in significant liability to us.

In addition, a crash caused by one of our components could damage our reputation for quality products. We believe our customers consider safety and reliability as key criteria in selecting a provider of aircraft components. If a crash were to be caused by one of our components, or if we were to otherwise fail to maintain a satisfactory record of safety and reliability, our ability to retain and attract customers may be materially adversely affected.

We have recorded a significant amount of intangible assets, which may never generate the returns we expect.

Mergers and acquisitions have resulted in significant increases in identifiable intangible assets and goodwill. Identifiable intangible assets, which primarily include trademarks, trade names, trade secrets, and technology, were approximately $1,217.2 million at September 30, 2014, representing approximately 18% of our total assets. Goodwill recognized in accounting for the mergers and acquisitions was approximately $3,525.1 million at September 30, 2014, representing approximately 52% of our total assets. We may never realize the full value of our identifiable intangible assets and goodwill, and to the extent we were to determine that our identifiable intangible assets or our goodwill were impaired within the meaning of applicable accounting standards, we would be required to write-off the amount of any impairment.

Our stock price may be volatile, and your investment in our common stock could suffer a decline in value.

There has been significant volatility in the market price and trading volume of equity securities, which is unrelated to the financial performance of the companies issuing the securities. These broad market fluctuations may negatively affect the market price of our common stock. You may not be able to sell your shares at or above the purchase price due to fluctuations in the market price of our common stock caused by changes in our operating performance or prospects, including possible changes due to the cyclical nature of the aerospace industry and other factors such as fluctuations in OEM and aftermarket ordering, which could cause short-term swings in profit margins, or unrelated to our operating performance, including market conditions affecting the stock market generally or the stocks of aerospace companies more specifically.

Future sales of our common stock in the public market could lower our share price.

We may sell additional shares of common stock into the public markets or issue convertible debt securities to raise capital in the future. The market price of our common stock could decline as a result of sales of a large number of shares of our common stock in the public markets or the perception that these sales could occur. These sales, or the possibility that these sales may occur, also might make it more difficult for us to sell equity securities to raise capital at a time and price that we deem appropriate.

Our corporate documents and Delaware law contain certain provisions that could discourage, delay or prevent a change in control of our company.

Provisions in our amended and restated certificate of incorporation and bylaws may discourage, delay or prevent a merger or acquisition involving us that our stockholders may consider favorable. For example, our amended and restated certificate of incorporation authorizes our Board of Directors to issue up to 149,600,000 shares of “blank check” preferred stock. Without stockholder approval, the Board of Directors has the authority to attach special rights, including voting and dividend rights, to this preferred stock. With these rights, holders of preferred stock could make it more difficult for a third party to acquire us. ~~In addition, our amended and restated certificate of incorporation provides for a staggered Board of Directors, whereby directors serve for three-year~~

terms, with approximately one-third of the directors coming up for re-election each year. Having a staggered board will make it more difficult for a third party to obtain control of our Board of Directors through a proxy contest, which may be a necessary step in an acquisition of us that is not favored by our Board of Directors. Our amended and restated certificate of incorporation also provides that the affirmative vote of the holders of at least 75% of the voting power of our issued and outstanding capital stock, voting together as a single class, is required for the alteration, amendment or repeal of certain provisions of our amended and restated certificate of incorporation ~~including the provisions authorizing a staggered board,~~ and certain provisions of our amended and restated bylaws, including the provisions relating to our stockholders’ ability to call special meetings, notice provisions for stockholder business to be conducted at an annual meeting, requests for stockholder lists and corporate records, nomination and removal of directors, and filling of vacancies on our Board of Directors.

We are also subject to the anti-takeover provisions of Section 203 of the Delaware General Corporation Law. Under these provisions, if anyone becomes an “interested stockholder,” we may not enter into a “business combination” with that person for three years without special approval, which could discourage a third party from making a takeover offer and could delay or prevent a change of control. For purposes of Section 203, “interested stockholder” means, generally, someone owning 15% or more of our outstanding voting stock or an affiliate of ours that owned 15% or more of our outstanding voting stock during the past three years, subject to certain exceptions as described in Section 203.

On October 15, 2012, July 3, 2013 and June 4, 2014 the Company’s board of directors authorized and declared a special cash ~~dividend~~dividends of $12.85, $22.00 and $25.00, respectively, on each outstanding share of common stock and cash dividend equivalent payments to holders of options under its stock option plans. ~~The special cash dividend amounting to approximately $664.3 million in the aggregate was paid in November 2012.~~

On July 3, 2013 the Company’s board of directors authorized and declared a special cash dividend of $22.00 on each outstanding share of common stock and cash dividend equivalent payments to holders of options under certain of its stock option plans. The special cash dividend amounting to approximately $1,155.8 million in the aggregate was paid in July 2013.

Notwithstanding the special cash dividends paid in October 2012, ~~and~~ July 2013 and June 2014, we do not anticipate declaring or paying regular quarterly or annual cash dividends on our common stock or any other equity security in the foreseeable future. The amounts that may be available to us to pay future special cash dividends are restricted under our debt and other agreements. Any payment of special cash dividends on our common stock in the future will be at the discretion of our Board of Directors and will depend on our results of operations, earnings, capital requirements, financial condition, future prospects, contractual restrictions and other factors deemed relevant by our Board of Directors. Therefore, you should not rely on regular quarterly or annual dividend income from shares of our common stock and you should not rely on special dividends with any regularity or at all.

Management believes that our machinery, plants and offices are in satisfactory operating condition and that it will have sufficient capacity to meet foreseeable future needs without incurring significant additional capital expenditures.

During the ordinary course of business, TransDigm is from time to time threatened with, or may become a party to, legal actions and other proceedings related to its businesses, products or operations. While TransDigm is currently involved in some legal proceedings, management believes the results of these proceedings will not have a material effect on its financial condition, results of operations, or cash flows.

On October 31, ~~2013,~~2014, there were 3641 stockholders of record of our common stock. We estimate that there were approximately ~~30,132~~44,227 beneficial stockholders as of October 31, ~~2013,~~2014, which includes an estimated amount of stockholders who have their shares held in their accounts by banks and brokers.

In June 2014 TD Group’s Board of Directors declared a special cash dividend of $25.00 on each outstanding share of common stock. In July 2013 TD Group’s Board of Directors declared a special cash dividend of $22.00 on each outstanding share of common stock.

Also, in July 2013 TD Group’s Board of Directors declared a special cash dividend of $22.00~~ on each outstanding share of common stock.

We do not anticipate declaring or paying regular quarterly or annual cash dividends on our common stock in the near future. Any payment of special cash dividends on our common stock in the future will be at the discretion of our Board of Directors and will depend upon our results of operations, earnings, capital requirements, financial condition, future prospects, contractual restrictions under our debt documents, the availability of surplus under Delaware law and other factors deemed relevant by our Board of Directors. TD Group is a holding company and conducts all of its operations through direct and indirect subsidiaries. Unless TD Group receives dividends, distributions, advances, transfers of funds or other payments from our subsidiaries, TD Group will be unable to pay any dividends on our common stock in the future. The ability of any subsidiaries to take any of the foregoing actions is limited by the terms of our debt documents and may be limited by future debt or other agreements that we may enter into.

In connection with the acquisition of the Company by Warburg Pincus in 2003, TD Group adopted a stock option plan for the benefit of our employees. The stock option plan has been amended and restated on several occasions, most recently effective as of July 18, 2008 and we refer to such stock option plan as it is currently in effect as the 2003 stock option plan.

~~Upon the closing~~ As of ~~the acquisition of the Company by Warburg Pincus, certain employees rolled over certain then-existing~~September 30, 2014, there were options to purchase shares of common stock of TransDigm Inc.’s former holding company with an aggregate intrinsic value of approximately $35.7 million into a combination of options to purchase shares of common stock of TD Group, or rollover options, and interests in the two deferred compensation plans which have since been terminated. These employees were granted rollover options to purchase an aggregate of 3,870,152324,511 shares of TD Group common stock which gives effect to the 149.60 for 1.00 stock split that we effected on March 14, 2006 in connection with our initial public offering. All rollover options granted in connection with the closing of the acquisition were fully vested on the date of grant. As of September 30, 2013, all rollover options were exercised.

In addition to the shares of TD Group common stock reserved for issuance upon exercise of rollover options, under the terms of the 2003 stock option plan, an aggregate of 5,469,301 shares of TD Group common stock are reserved for issuance upon exercise of new management options (after giving effect to the stock split). As of September 30, 2013, there were new management options to purchase 550,476 shares of TD Group common stock outstanding (after giving effect to the stock split).outstanding. As of September 30, 2013, there were no shares available for issuance under options not yet granted. The stock option plan has expired and no further grants will be made from the plan.

Prior to the consummation of its initial public offering, TD Group adopted a new stock incentive plan, which was amended most recently on ~~October 20, 2006, July 29, 2008 and~~ March 3, 2011. The plan is designed to assist us in attracting, retaining, motivating and rewarding key employees, directors or consultants, and promoting the creation of long-term value for stockholders of TD Group by closely aligning the interests of these individuals with those of our stockholders. The 2006 stock incentive plan permits TD Group to award our key employees, directors or consultants stock options, restricted stock and other stock-based incentives.

As of September 30, ~~2013,~~2014, there were ~~23,657~~23,989 shares of common stock issued and outstanding under the 2006 stock incentive plan that had been issued to directors.

The stock incentive plan will expire on March 14, 2016 and no further shares will be granted under the plan thereafter.

In July 2014, the board of directors of TD Group adopted a new stock option plan, which was subsequently approved by stockholders on October 2, 2014. The plan is designed to assist us in attracting, retaining, motivating and rewarding key employees, directors or consultants, and promoting the creation of long-term value for stockholders of TD Group by closely aligning the interests of these individuals with those of our stockholders. The 2014 stock option plan permits TD Group to award our key employees, directors or consultants stock options. The total number of shares of TD Group common stock reserved for issuance or delivery under the 2014 stock option plan is 5,000,000, subject to adjustment in the event of any stock dividend or split, reorganization, recapitalization, merger, share exchange or any other similar corporate transaction or event. As of September 30, 2014, there were no options to purchase shares issued thereunder.

The following table sets forth selected historical consolidated financial and other data of TD Group for the fiscal years ended September 30, ~~2009~~2010 to ~~2013~~2014 which have been derived from TD Group’s audited consolidated financial statements.

Separate historical financial information of TransDigm Inc. is not presented since the 2018 Notes, 2020 Notes, 2021 Notes, 2022 Notes and the ~~2021~~2024 Notes are guaranteed by TD Group and all direct and indirect domestic restricted subsidiaries of TransDigm Inc. and since TD Group has no operations or significant assets separate from its investment in TransDigm Inc.

Acquisitions of businesses and product lines completed by TD Group during the last five fiscal years are as follows:

All of the acquisitions were accounted for using the acquisition method. The results of operations of the acquired businesses and product lines are included in TD Group’s consolidated financial statements from the date of each of the acquisitions.

We present below certain financial information based on our EBITDA and EBITDA As Defined. References to “EBITDA” mean earnings before interest, taxes, depreciation and amortization, and references to “EBITDA As Defined” mean EBITDA plus, as applicable for each relevant period, certain adjustments as set forth in the reconciliations of net income to EBITDA and EBITDA As Defined and the reconciliations of net cash provided by operating activities to EBITDA and EBITDA As Defined presented below.

Neither EBITDA nor EBITDA As Defined is a measurement of financial performance under accounting principles generally accepted in the United States of America (“GAAP”). We present EBITDA and EBITDA As Defined because we believe they are useful indicators for evaluating operating performance and liquidity.

Our management believes that EBITDA and EBITDA As Defined are useful as indicators of liquidity because securities analysts, investors, rating agencies and others use EBITDA to evaluate a company’s ability to incur and service debt. In addition, EBITDA As Defined is useful to investors because the revolving credit facility under our senior secured credit facility requires compliance under certain circumstances, on a pro forma basis, with a financial covenant that measures the ratio of the amount of our secured indebtedness to the amount of our Consolidated EBITDA defined in the same manner as we define EBITDA As Defined herein.

In addition to the above, our management uses EBITDA As Defined to review and assess the performance of the management team in connection with employee incentive programs and to prepare its annual budget and financial projections. Moreover, our management uses EBITDA As Defined to evaluate acquisitions.

Although we use EBITDA and EBITDA As Defined as measures to assess the performance of our business and for the other purposes set forth above, the use of these non-GAAP financial measures as analytical tools has limitations, and you should not consider any of them in isolation, or as a substitute for analysis of our results of operations as reported in accordance with GAAP. Some of these limitations are:

Because of these limitations, EBITDA and EBITDA As Defined should not be considered as measures of discretionary cash available to us to invest in the growth of our business. Management compensates for these limitations by not viewing EBITDA or EBITDA As Defined in isolation and specifically by using other GAAP measures, such as net income, net sales and operating profit, to measure our operating performance. Neither EBITDA nor EBITDA As Defined is a measurement of financial performance under GAAP, and neither should be considered as an alternative to net income or cash flow from operations determined in accordance with GAAP. Our calculation of EBITDA and EBITDA As Defined may not be comparable to the calculation of similarly titled measures reported by other companies.

The information presented below should be read together with “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and the consolidated financial statements and accompanying notes included elsewhere herein.

ITEM 7.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion of our financial condition and results of operations should be read together with “Selected Financial Data” and TD Group’s consolidated financial statements and the related notes included elsewhere in this report. The following discussion may contain predictions, estimates and other forward-looking statements that involve a number of risks and uncertainties, including those discussed under the heading entitled “Risk Factors” included elsewhere in this report. These risks could cause our actual results to differ materially from any future performance suggested below.

We believe we are a leading global designer, producer and supplier of highly engineered aircraft components for use on nearly all commercial and military aircraft in service today. Our business is well diversified due to the broad range of products we offer to our customers. Some of our more significant product offerings, substantially all of which are ultimately provided to end-users in the aerospace industry, include mechanical/electro-mechanical actuators and controls, ignition systems and engine technology, specialized pumps and valves, power conditioning devices, specialized AC/DC electric motors and generators, NiCad batteries and chargers, engineered latching and locking devices, rods and locking devices, engineered connectors and elastomers, cockpit security components and systems, specialized cockpit displays, aircraft audio systems, specialized lavatory components, seatbelts and safety restraints, engineered interior surfaces, ~~and~~ lighting and control ~~technology.~~technology and military personnel parachutes and cargo delivery systems. Each of these product offerings is composed of many individual products that are typically customized to meet the needs of a particular aircraft platform or customer.

For fiscal year ~~2013,~~2014, we generated net sales of ~~$1,924.4~~$2,372.9 million, gross profit of ~~$1,049.6~~$1,267.9 million or ~~54.5%~~53.4% of sales, and net income of ~~$302.8~~$306.9 million. We believe we have achieved steady, long-term growth in sales and improvements in operating performance since our formation in 1993 due to our competitive strengths and through execution of our value-driven operating strategy. More specifically, focusing our businesses on our value-driven operating strategy of obtaining profitable new business, carefully controlling the cost structure and pricing our highly engineered value-added products to fairly reflect the value we provide and the resources required to do so has historically resulted in improvements in gross profit and income from operations over the long term.

Our selective acquisition strategy has also contributed to the growth of our business. The integration of certain acquisitions into our existing businesses combined with implementing our proven operating strategy has historically resulted in improvements of the financial performance of the acquired business.

Our key competitive strengths and the elements of our business strategy are set forth in more detail below.

Large and Growing Installed Product Base with Aftermarket Revenue Stream.We provide components to a large and growing installed base of aircraft to which we supply aftermarket products. We estimate that our products are installed on approximately ~~90,000~~93,000 commercial transport, regional transport, military and general aviation fixed wing turbine aircraft and rotary wing aircraft.

Diversified Revenue Base.We believe that our diversified revenue base reduces our dependence on any particular product, platform or market channel and has been a significant factor in maintaining our financial performance. Our products are installed on almost all of the major commercial aircraft platforms now in production. We expect to continue to develop new products for military and commercial applications.

Significant Barriers to Entry. We believe that the niche nature of our markets, the industry’s stringent regulatory and certification requirements, the large number of products that we sell and the investments necessary to develop and certify products create barriers to entry for potential competitors.

Our business strategy is made up of two key elements: (1) a value-driven operating strategy focused around our three core value drivers and (2) a selective acquisition strategy.

Selective Acquisition Strategy.We selectively pursue the acquisition of proprietary aerospace component businesses when we see an opportunity to create value through the application of our three core value-driven operating strategies. The aerospace industry, in particular, remains highly fragmented, with many of the companies in the industry being small private businesses or small non-core operations of larger businesses. We have significant experience among our management team in executing acquisitions and integrating acquired businesses into our company and culture. As of the date of this report, we have successfully acquired 4649 businesses and/or product lines since our formation in 1993. Many of these acquisitions have been integrated into an existing TransDigm production facility, which enables a higher production capacity utilization, which in turn improves gross profit levels due to the ability to spread the fixed manufacturing overhead costs over higher production volume.

We predominantly serve customers in the commercial, regional, business jet and general aviation aftermarket, which accounts for approximately ~~39%~~37% of total sales; the commercial aerospace OEM market, comprising large commercial transport manufacturers and regional and business jet manufacturers, which accounts for approximately ~~30%~~28% of total sales; and the defense market, which accounts for approximately ~~25%~~30% of total sales. Non-aerospace sales comprise approximately 6%5% of our total sales.

The commercial aerospace industry, including the aftermarket and OEM market, is impacted by the health of the global economy and geo-political events around the world. The commercial aerospace industry had shown strength with increases in revenue passenger miles, or RPMs, between 2003 and 2008, as well as increases in OEM production and backlog. However, in 2009, the global economic downturn negatively impacted the commercial aerospace industry causing RPMs to decline slightly. This market sector began to rebound in 2010 and positive growth has continued thru ~~2013~~2014 with increases in RPMs, as well as the growth in the large commercial OEM sector (aircraft with 100 or more seats) with order announcements by The Boeing Company and Airbus S.A.S. leading to planned increases in production. The ~~2014~~2015 leading indicators and industry consensus suggest a continuation of current trends in the commercial transport market sector supported by continued RPM growth and increases in production at the OEM level.

The defense aerospace market is dependent on government budget constraints, the timing of orders and the extent of global conflicts. It is not necessarily affected by general economic conditions that affect the commercial aerospace industry.

Our presence in both the commercial aerospace and military sectors of the aerospace industry may mitigate the impact on our business of any specific industry risk. We service a diversified customer base in the commercial and military aerospace industry, and we provide components to a diverse installed base of aircraft, which mitigates our exposure to any individual airframe platform. At times, declines in sales in one channel have been offset by increased sales in another. However, due to differences between the profitability of our products sold to OEM and aftermarket customers, variation in product mix can cause variation in gross margin.

There are many short-term factors (including inventory corrections, unannounced changes in order patterns, strikes and mergers and acquisitions) that can cause short-term disruptions in our quarterly shipment patterns as compared to previous quarters and the same periods in prior years. As such, it can be difficult to determine longer-term trends in our business based on quarterly comparisons. To normalize for short-term fluctuations, we tend to look at our performance over several quarters or years of activity rather than discrete short-term periods.

There are also fluctuations in OEM and aftermarket ordering and delivery requests from quarter-to-quarter, as well as variations in product mix from quarter-to-quarter, that may cause positive or negative variations in gross profit margins since commercial aftermarket sales have historically produced a higher gross margin than sales to commercial OEMs. Again, in many instances these are timing events between quarters and must be balanced with macro aerospace industry indicators.

The key growth factors in the commercial aftermarket include worldwide RPMs and the size and activity level of the worldwide fleet of aircraft. After a decline in RPMs in 2009, worldwide RPMs returned to growth between 2010 and ~~2013~~2014 and current industry consensus indicates that positive RPM growth will continue in ~~2014.~~2015.

The commercial transport market sector continued to grow during ~~2013.~~2014. Our commercial transport OEM shipments and revenues generally run ahead of the Boeing and Airbus airframe delivery schedules. As a result and consistent with prior years, our fiscal ~~2014~~2015 shipments will be a function of, among other things, the estimated ~~2014~~2015 and ~~2015~~2016 commercial airframe production rates. We ~~are now~~have been experiencing increased sales in the large commercial OEM sector (aircraft with 100 or more seats) driven by an increase in production by The Boeing Company and Airbus S.A.S tied to previous order announcements. Industry consensus indicates this production increase will continue in ~~2014~~2015 and ~~2015,~~2016, though the growth may ~~moderate.~~moderate and begin to flatten.

The business jet OEM market significantly declined between 2008 and 2010, impacted by the slowdown in economic growth, corporate profits, commodity prices and stock market returns across the world. However, the business jet OEM market started to modestly recover in ~~2011~~2012, but has remained sluggish through ~~2013~~2014 and could show modest growth in ~~2014.~~2015.

Our military business fluctuates from year to year, and is dependent, to a degree, on government budget constraints, the timing of orders and the extent of global conflicts. In recent years, defense spending has reached historic highs, due in part to the military engagements in Afghanistan and Iraq and the war on terrorism. ~~We anticipate~~For a variety of reasons, the military spending outlook is very uncertain. For planning purposes we assume that military related sales of our types of products ~~could start~~ to ~~decline~~be flat to modestly down in future years over the ~~current~~recent high levels.

Our consolidated financial statements have been prepared in conformity with GAAP, which often requires the judgment of management in the selection and application of certain accounting principles and methods. Management believes that the quality and reasonableness of our most critical policies enable the fair presentation of our financial position and results of operations. However, investors are cautioned that the sensitivity of financial statements to these methods, assumptions and estimates could create materially different results under different conditions or using different assumptions.

~~We have identified~~Below are those policies applied in preparing our financial statements that management believes are the most dependent on the application of estimates and assumptions. For additional accounting policies, ~~below as critical~~see Note 3, “Summary of Significant Accounting Policies” in the notes to ~~our business operations and~~ the understanding of our results of operations. These critical policies were determined by considering accounting policies that involve the most complex or subjective decisions or assessments. Our most critical accounting policies are as follows:consolidated financial statements included herein.

Revenue Recognition and Related Allowances: Revenue is recognized from the sale of products when title and risk of loss passes to the customer, which is generally at the time of shipment. Substantially all product sales are made pursuant to firm, fixed-price purchase orders received from customers. Collectability of amounts recorded as revenue is reasonably assured at the time of sale. Provisions for returns, uncollectible accounts and the cost of repairs under contract warranty provisions are provided for in the same period as the related revenues are recorded and are principally based on historical results modified, as appropriate, by the most current information available. We have a history of making reasonably dependable estimates of such allowances; however, due to uncertainties inherent in the estimation process, it is possible that actual results may vary from the estimates and the differences could be material.

Management estimates the allowance for doubtful accounts based on the aging of the accounts receivable and customer creditworthiness. The allowance also incorporates a provision for the estimated impact of disputes with customers. Management’s estimate of the allowance amounts that are necessary includes amounts for specifically identified credit losses and estimated credit losses based on historical information. The determination of the amount of the allowance for doubtful accounts is subject to significant levels of judgment and estimation by management. Depending on the resolution of potential credit and other collection issues, or if the financial condition of any of the Company’s customers were to deteriorate and their ability to make required payments were to become impaired, increases in these allowances may be required. Historically, changes in estimates in the allowance for doubtful accounts have not been significant.

The Company provides limited warranties in connection with the sale of its products. The warranty period for products sold, which varies among the Company’s operations, is typically less than two years but can be in the range from 90 days to six years. In addition, certain contracts with distributors contain right of return provisions. The Company accrues for estimated returns and warranty claims based on knowledge of product performance issues and based on excess inventories provided by its customers and industry sources. The

Company also provides a general amount based on historical trends. To the extent total warranty claims differ from estimates, adjustments may be necessary. Historically, actual product returns and warranty claims have not differed materially from the estimates originally established.

Inventories: Inventories are stated at the lower of cost or market. Cost of inventories is determined by the average cost and the first-in, first-out (FIFO) methods for all locations except CEF Industries, LLC, which determines the cost of inventories using the last-in, first-out (LIFO) method. Because the Company sells products that are installed on airframes that can be in-service for 3025 or more years, it must keep a supply of such products on hand while the airframes are in use. Where management estimated that the current market value was below cost or determined that future demand was lower than current inventory levels, based on historical experience,

current and projected market demand, current and projected volume trends and other relevant current and projected factors associated with the current economic conditions, a reduction in inventory cost to estimated net realizable value was made by recording a provision included in cost of sales. Although management believes that the Company’s estimates of excess and obsolete inventory are reasonable, actual results may differ materially from the estimates and additional provisions may be required in the future. In addition, in accordance with industry practice, all inventories are classified as current assets as all inventories are available and necessary to support current sales, even though a portion of the inventories may not be sold within one year. Historically, changes in estimates in the net realizable value of inventories have not been significant.

Intangible Assets: Mergers and acquisitions are accounted for using the acquisition method and have resulted in significant amounts of identifiable intangible assets and goodwill. Fair value adjustments to the Company’s assets and liabilities are recognized and the results of operations of the acquired business are included in our consolidated financial statements from the effective date of the merger or acquisition. We generally use third-party appraisals to assist us in determining the estimated fair value of the intangible assets.

Intangible assets other than goodwill are recognized if the benefit of the intangible asset is obtained through contractual or other legal rights, or if the intangible asset can be sold, transferred, licensed or exchanged, regardless of the Company’s intent to do so. Goodwill and identifiable intangible assets are recorded at their estimated fair value on the date of acquisition and are reviewed at least annually for impairment based on cash flow projections and fair value estimates.

GAAP requires that the annual, and any interim, impairment assessment be performed at the reporting unit level. The reporting unit level is one level below an operating segment. Substantially all goodwill was determined and recognized for each reporting unit pursuant to the accounting for the merger or acquisition as of the date of each transaction. With respect to acquisitions integrated into an existing reporting unit, any acquired goodwill is combined with the goodwill of the reporting unit.

At the time of goodwill impairment testing, management determines the estimated fair value through the use of a discounted cash flow valuation model incorporating discount rates commensurate with the risks involved for each reporting unit. If the calculated estimated fair value is less than the current carrying value, impairment of goodwill of the reporting unit may exist. The use of a discounted cash flow valuation model to determine estimated fair value is common practice in impairment testing. The key assumptions used in the discounted cash flow valuation model for impairment testing includes discount rates, growth rates, cash flow projections and terminal value rates. Discount rates are set by using the Weighted Average Cost of Capital (“WACC”) methodology. The WACC methodology considers market and industry data as well as company specific risk factors for each reporting unit in determining the appropriate discount rates to be used. The discount rate utilized for each reporting unit is indicative of the return an investor would expect to receive for investing in such a business.

Management, considering industry and company-specific historical and projected data, develops growth rates, sales projections and cash flow projections for each reporting unit. Terminal value rate determination follows common methodology of capturing the present value of perpetual cash flow estimates beyond the last

projected period assuming a constant WACC and low long-term growth rates. As an indicator that each reporting unit has been valued appropriately through the use of the discounted cash flow valuation model, the aggregate of all reporting ~~units~~unit’s estimated fair value is reconciled to the total market capitalization of the Company.

The Company had 2427 reporting units with goodwill as of the first day of the fourth quarter of fiscal ~~2013,~~2014, the date of the last annual impairment test. The estimated fair values of each of the reporting units was substantially in excess of their respective carrying values (by 4019 percent or more), and therefore no goodwill impairment was recorded. The Company performed a sensitivity analysis on the discount rate, which is a significant assumption in the calculation of fair values. With a one percentage point increase in the discount rate, the reporting units would continue to have fair values in excess of their respective carrying values.

Management tests indefinite-lived intangible assets for impairment at the asset level, as determined by appropriate asset valuation at the time of acquisition. The impairment test for indefinite-lived intangible assets consists of a comparison between the estimated fair values and carrying values. If the carrying amounts of intangible assets that have indefinite useful lives exceed their estimated fair values, an impairment loss will be recognized in an amount equal to the difference. Management utilizes the royalty savings valuation method to determine the estimated fair value for each indefinite-lived intangible asset. In this method, management estimates the royalty savings arising from the ownership of the intangible asset. The key assumptions used in estimating the royalty savings for impairment testing include discount rates, royalty rates, growth rates, sales projections and terminal value rates. Discount rates used are similar to the rates developed by the WACC methodology considering any differences in company-specific risk factors between reporting units and the indefinite-lived intangible assets. Royalty rates are established by management with the advice of valuation experts and periodically substantiated by valuation experts. Management, considering industry and company-specific historical and projected data, develops growth rates and sales projections for each significant intangible asset. Terminal value rate determination follows common methodology of capturing the present value of perpetual sales estimates beyond the last projected period assuming a constant WACC and low long-term growth rates.

The discounted cash flow and royalty savings valuation methodologies require management to make certain assumptions based upon information available at the time the valuations are performed. Actual results could differ from these assumptions. Management believes the assumptions used are reflective of what a market participant would have used in calculating fair value considering the current economic conditions.

~~Stock Options~~: The Company accounts for the cost of its stock options in accordance with GAAP, which requires the measurement of compensation expense under the stock option plan to be based on the estimated fair value of the awards under the plan on the grant dates and amortizes the expense over the vesting periods of the options. The Company estimates the fair value of all share-based payments using the Black-Scholes-Merton option pricing model which requires management to make certain assumptions. Management continuously reviews the following assumptions: risk-free interest rates, expected life of options, expected volatility of stock and expected dividend yield of stock. An increase or decrease in the assumptions or economic events outside management’s control could have an impact on the Company’s results of operations.

~~Environmental Matters~~: The Company is involved with environmental investigation and remediation activities at some of its currently and formerly owned sites and at third-party sites. The Company accrues for environmental-related activities for which commitments or clean-up plans have been developed and for which costs can be reasonably estimated based on industry standards and professional judgment. All accrued amounts were recorded on an undiscounted basis. Environmental-related expenses include costs of investigation and remediation and fees paid to outside engineering, actuarial, consulting and law firms. Due to uncertainties surrounding environmental investigations and remediation activities, the Company’s ultimate liability may result in costs that are significantly higher than currently accrued.

Income Taxes: The Company estimates income taxes in each jurisdiction in which it operates. This involves estimating taxable earnings, specific taxable and deductible items, the likelihood of generating sufficient future

taxable income to utilize deferred tax assets and possible exposures related to future tax audits. To the extent these estimates change, adjustments to deferred and accrued income taxes are made in the period in which the changes occur. Historically, such adjustments have not been significant.

Fiscal year ended September 30, 2014 compared with fiscal year ended September 30, 2013

Net Sales. Net organic sales and acquisition sales and the related dollar and percentage changes for the fiscal years ended September 30, 2014 and 2013 were as follows (amounts in millions):

Acquisition sales represent sales of acquired businesses for the period up to one year subsequent to their acquisition dates. The amount of acquisition sales shown in the table above was mainly attributable to the acquisition of Airborne and EME in fiscal 2014 and Whippany Actuation, Arkwin and Aerosonic in fiscal 2013.

Organic sales for the fiscal year ended September 30, 2013 include a favorable commercial OEM retroactive contract pricing adjustment of approximately $2 million. Excluding the impact of the retroactive contract pricing adjustment, commercial OEM sales increased $49.3 million or an increase of 8.6%, commercial aftermarket sales increased $90.1 million, or an increase of 12.0%, and defense sales increased $26.5 million, or an increase of 5.5%, for the fiscal year ended September 30, 2014 compared to the fiscal year ended September 30, 2013.

Cost of Sales and Gross Profit. Cost of sales increased by $230.2 million, or 26.3%, to $1,105.0 million for the fiscal year ended September 30, 2014 compared to $874.8 million for the fiscal year ended September 30, 2013. Cost of sales and the related percentage of total sales for the fiscal years ended September 30, 2014 and 2013 were as follows (amounts in millions):

The increase in the dollar amount of cost of sales during the fiscal year ended September 30, 2014 was primarily due to increased volume associated with the sales from acquisitions and organic sales growth partially offset by lower stock compensation expense related to the accelerated vesting in the prior year (discussed further below) and lower acquisition-related costs as shown in the table above.

Gross profit as a percentage of sales decreased by 1.1 percentage points to 53.4% for the fiscal year ended September 30, 2014 from 54.5% for the fiscal year ended September 30, 2013. The dollar amount of gross profit increased by $218.3 million, or 20.8%, for the fiscal year ended September 30, 2014 compared to the comparable period last year due to the following items:

Selling and Administrative Expenses.Selling and administrative expenses increased by $22.0 million to $276.4 million, or 11.6% of sales, for the fiscal year ended September 30, 2014 from $254.5 million, or 13.2% of sales, for the comparable period last year. Selling and administrative expenses and the related percentage of total sales for the fiscal years ended September 30, 2014 and 2013 were as follows (amounts in millions):

The increase in the dollar amount of selling and administrative expenses during the fiscal year ended September 30, 2014 is primarily due to higher selling and administrative expenses relating to recent acquisitions of approximately $35 million, which was approximately 12% of the acquisition sales, partially offset by lower acquisition related expenses of approximately $3 million and by lower stock compensation expense of approximately $19 million. Stock compensation expense was higher in fiscal 2013 primarily due to accelerated vesting under the market sweep provision for all options granted prior to October 1, 2011.

Amortization of Intangible Assets.Amortization of intangible assets increased to $63.6 million for the fiscal year ended September 30, 2014 from $45.6 million for the comparable period last year. The net increase of $18.0 million was primarily due to amortization expense related to the additional identifiable intangible assets recognized in connection with acquisitions during the last twelve months.

Refinancing Costs. Refinancing costs of $131.6 million were recorded during the year ended September 30, 2014 representing debt issue costs expensed in conjunction with the repurchase of the 2018 Notes. The charge consisted of the premium of $121.1 million paid to redeem the 2018 Notes and the write-off of debt issue costs of

$10.5 million. Refinancing costs of $30.3 million were recorded during the fiscal year ended September 30, 2013 representing debt issue costs expensed in conjunction with the refinancing of our 2010 Credit Facility and 2011 Credit Facility in February 2013.

Interest Expense-net.Interest expense-net includes interest on outstanding borrowings, amortization of debt issue costs and revolving credit facility fees offset by interest income. Interest expense-net increased $77.0 million, or 28.4%, to $347.7 million for the fiscal year ended September 30, 2014 from $270.7 million for the comparable period last year. The net increase in interest expense-net was primarily due to an increase in the weighted average level of outstanding borrowings, which was approximately $6.31 billion for the fiscal year ended September 30, 2014 and approximately $4.63 billion for the fiscal year ended September 30, 2013 slightly offset by a decrease in the weighted average cash interest rate during the fiscal year ended September 30, 2014 of 5.3% compared to the weighted average cash interest rate during the comparable prior period of 5.6%. The increase in weighted average level of borrowings was primarily due to additional borrowings of $900 million relating to the incremental term loan in July 2013, the issuance in July 2013 of the $500 million 2021 Notes, the issuance in June 2014 of the $2,350 million 2022 and 2024 Notes, borrowings under the trade receivable securitization facility in June 2014, and the issuance in June 2014 of $825 million of additional borrowings under the 2014 Credit Facility. The weighted average interest rate for cash interest payments on total outstanding borrowings at September 30, 2014 was 4.9%.

Income Taxes.Income tax expense as a percentage of income before income taxes was approximately 31.6% for the fiscal year ended September 30, 2014 compared to 32.5% for the fiscal year ended September 30, 2013. The Company’s effective tax rate for these periods was less than the Federal statutory tax rate due primarily to the domestic manufacturing deduction. The decrease in the effective tax rate for the fiscal year ended September 30, 2014 compared to the fiscal year ended September 30, 2013 was primarily due to the ability to recognize the benefit from the utilization of foreign tax credits in the current year and discrete items related to adjustments resulting from the filing of the Company’s September 30, 2013 U.S. tax return partially offset by the expiration of the research and development tax credit.

Net Income. Net income increased $4.1 million, or 1.4%, to $306.9 million for the fiscal year ended September 30, 2014 compared to net income of $302.8 million for the year ended September 30, 2013. The increase in net income is primarily due to growth in net sales described above and a lower effective tax rate offset by higher interest expense as a result of an increase in the level of outstanding borrowings and one-time costs of $90.1 million, net of tax, or $1.58 per share, attributable to the refinancing of our capital structure in June 2014.

Earnings per Share. The basic and diluted earnings per share were $3.16 for the fiscal year ended September 30, 2014 and $2.39 per share for the fiscal year ended September 30, 2013. Net income for the fiscal year ended September 30, 2014 of $306.9 million was decreased by dividend equivalent payments of $126.6 million resulting in net income available to common shareholders of $180.3 million. Net income for the fiscal year ended September 30, 2013 of $302.8 million was decreased by dividend equivalent payments of $171.2 million resulting in net income available to common shareholders of $131.5 million. The increase in earnings per share of $0.77 per share to $3.16 per share is a result of the factors referred to above.

Segment Net Sales. Net sales by segment for the fiscal years ended September 30, 2014 and 2013 were as follows (amounts in millions):

Sales for the Power & Control segment, excluding acquisitions, increased approximately $49 million when compared to the fiscal year ended September 30, 2013. The sales increase was primarily due to an increase in commercial aftermarket sales of approximately $40 million, or an increase of 11.7%, and an increase in defense sales of approximately $8 million, or an increase of 2.3%. Acquisition sales totaled $156 million, or a 17.9% increase in segment sales, resulting from the acquisitions of EME in fiscal 2014 and Whippany Actuation and Arkwin in fiscal 2013.

Sales for the Airframe segment, excluding acquisitions and OEM retroactive contract pricing adjustments, increased approximately $117 million when compared to the fiscal year ended September 30, 2013. The sales increase was primarily due to an increase in commercial aftermarket sales of approximately $50 million, or an increase of 12.3%, an increase in commercial OEM sales of approximately $48 million, or an increase of 12.0%, and an increase in defense sales of approximately $20 million, or a increase of 14.9%. Acquisition sales for the Airframe segment totaled $134 million, or a 14.1% increase in segment sales, resulting from the acquisitions of Airborne in fiscal 2014 and Aerosonic in fiscal 2013. The fiscal year ended September 30, 2013, reflects an OEM retroactive contract pricing adjustment of approximately $2 million.

Acquisition sales for the Non-aviation segment totaled $3 million, or an increase of 2.8%. Organic sales declined $8 million, or 7.9%.

EBITDA As Defined. EBITDA As Defined by segment for the fiscal years ended September 30, 2014 and 2013 were as follows (amounts in millions):

EBITDA As Defined for the Power & Control segment, excluding acquisitions, increased approximately $44 million when compared to the fiscal year ended September 30, 2013 due to increases in defense sales and commercial aftermarket sales. EBITDA As Defined from the acquisitions in fiscal 2014 and 2013 was approximately $51 million for the fiscal year ended September 30, 2014.

EBITDA As Defined for the Airframe segment, excluding acquisitions and a prior year retroactive pricing adjustment, increased approximately $59 million when compared to the fiscal year ended September 30, 2013. The increase was primarily due to the increases in commercial OEM and commercial aftermarket sales and defense sales. EBITDA As Defined from the acquisitions of Aerosonic and Airborne was approximately $28 million for the fiscal year ended September 30, 2014. The year ended September 30, 2013 reflects EBITDA As Defined of approximately $2 million relating to the previously mentioned retroactive contract pricing adjustment.

EBITDA As Defined for the Non-aviation segment acquisition was approximately $0.4 million for the fiscal year ended September 30, 2014. Organic EBITDA declined approximately $5.5 million due to the organic sales decrease noted above and the mix of products sold in the non-aviation markets.

Fiscal year ended September 30, 2013 compared with fiscal year ended September 30, 2012

Net Sales. Net organic sales, acquisition sales and sales of the AmSafe distribution business, which was acquired as part of AmSafe on February 15, 2012 and sold on August 16, 2012, and the related dollar and percentage changes for the fiscal years ended September 30, 2013 and 2012 were as follows (amounts in millions):

Acquisition sales represent sales of acquired businesses for the period up to one year subsequent to their acquisition dates. The amount of acquisition sales shown in the table above was mainly attributable to the acquisition of Whippany Actuation, Arkwin and Aerosonic in fiscal 2013 and Aero-Instruments, AmSafe and Harco in fiscal 2012.

Organic sales for the fiscal year ended September 30, 2013 include a favorable commercial OEM retroactive contract pricing adjustment of approximately $2 million. Organic sales for the fiscal year ended September 30, 2012 include favorable commercial OEM retroactive contract pricing adjustments of approximately $13 million and a favorable commercial aftermarket retroactive contract pricing adjustment of approximately $6 million.

Excluding the impact of the retroactive contract pricing adjustments and the AmSafe distribution sales indicated above, commercial OEM sales increased $51.4 million, or an increase of 10.5%, commercial aftermarket sales increased $3.3 million, or an increase of 0.5%, and defense sales increased $33.1 million, or an increase of 8.3%, for the fiscal year ended September 30, 2013 compared to the fiscal year ended September 30, 2012. The commercial aftermarket comparable sales, particularly in the second half of fiscal 2013 compared to the second half of fiscal 2012, were negatively impacted by non-market items associated with changing past business practices of previously-acquired businesses, changes in distributors and related inventory fluctuations. We believe that the underlying demand in the commercial aftermarket channel began to trend up more positively during the second half of the fiscal year.

Cost of Sales and Gross Profit. Cost of sales increased by $120.3 million, or 16.0%, to $874.8 million for the fiscal year ended September 30, 2013 compared to $754.5 million for the fiscal year ended September 30, 2012. Cost of sales and the related percentage of total sales for the fiscal years ended September 30, 2013 and 2012 were as follows (amounts in millions):

Gross profit percentage		54.5	%		55.6	%								54.5	%		55.6	%

The increase in the dollar amount of cost of sales during the fiscal year ended September 30, 2013 was primarily due to increased volume associated with the sales from acquisitions and organic sales growth and higher stock compensation expense related to the accelerated vesting (discussed further below) partially offset by lower acquisition-related costs as shown in the table above.

Gross profit as a percentage of sales decreased by 1.1 percentage points to 54.5% for the fiscal year ended September 30, 2013 from 55.6% for the fiscal year ended September 30, 2012. The dollar amount of gross profit increased by $103.8 million, or 11.0%, for the fiscal year ended September 30, 2013 compared to the comparable period last year due to the following items:

Selling and Administrative Expenses.Selling and administrative expenses increased by $52.8 million to $254.5 million, or 13.2% of sales, for the fiscal year ended September 30, 2013 from $201.7 million, or 11.9% of sales, for the comparable period last year. Selling and administrative expenses and the related percentage of total sales for the fiscal years ended September 30, 2013 and 2012 were as follows (amounts in millions):

% of total sales		13.2	%		11.9	%							13.2	%		11.9	%

The increase in the dollar amount of selling and administrative expenses during the fiscal year ended September 30, 2013 is primarily due to higher selling and administrative expenses relating to recent acquisitions of approximately $25 million, which was approximately 14% of the acquisition sales, and additional stock compensation expense of approximately $21 million recorded in June 2013 related to the accelerated vesting under the market sweep provision for all options granted prior to October 1, 2011.

Amortization of Intangible Assets.Amortization of intangible assets increased to $45.6 million for the fiscal year ended September 30, 2013 from $44.2 million for the comparable period last year. The net increase of $1.4 million was primarily due to amortization expense related to the additional identifiable intangible assets recognized in connection with acquisitions during the last twelve months partially offset by order backlog relating to prior acquisitions becoming fully amortized.

Refinancing Costs. Refinancing costs of $30.3 million were recorded during the fiscal year ended September 30, 2013 representing debt issue costs expensed in conjunction with the refinancing of our 2010 Credit Facility and 2011 Credit Facility in February 2013.

Interest Expense-net.Interest expense-net includes interest on outstanding borrowings, amortization of debt issue costs and revolving credit facility fees offset by interest income. Interest expense-net increased $58.8 million, or 27.7%, to $270.7 million for the fiscal year ended September 30, 2013 from $211.9 million for the comparable period last year. The net increase in interest expense-net was primarily due to an increase in the weighted average level of outstanding borrowings, which was approximately $4.63 billion for the fiscal year ended September 30, 2013 and approximately $3.44 billion for the fiscal year ended September 30, 2012 slightly offset by a decrease in the weighted average cash interest rate during the fiscal year ended September 30, 2013 of 5.6% compared to the weighted average cash interest rate during the comparable prior period of 6.2%. The increase in borrowings was primarily due to the additional $150 million term loan facility under the amendments to our 2011 Credit Facility which occurred in October 2012, additional borrowings of $36.4 million relating to our

refinancing of the 2011 Credit Facility in February 2013, additional borrowings of $900 million relating to the Incremental Term Facility in July 2013, the issuance in October 2012 of our $550 million 2020 Notes and the issuance in July 2013 of our $500 million 2021 Notes. The weighted average interest rate for cash interest payments on total outstanding borrowings at September 30, 2013 was 5.4%.

Income Taxes.Income tax expense as a percentage of income before income taxes was approximately 32.5% for the fiscal year ended September 30, 2013 compared to 33.4% for the fiscal year ended September 30, 2012. The Company’s effective tax rate for these periods was less than the Federal statutory tax rate due primarily to the domestic manufacturing deduction. The decrease in the effective tax rate for the fiscal year ended September 30, 2013 compared to the fiscal year ended September 30, 2012 was primarily due to the retroactive reinstatement of the research and development tax credit and an increased benefit from the domestic manufacturing deduction.

Net ~~Income.~~Income. Net income decreased $22.2 million, or 6.8%, to $302.8 million for the fiscal year ended September 30, 2013 compared to net income of $325.0 million for the year ended September 30, 2012. The decrease in net income was primarily due to the higher interest expense-net discussed above, the after-tax impact of $20.4 million, or $0.37 per share, related to the refinancing costs recorded during the period and the after-tax additional stock compensation expense recorded in June 2013 of $16.6 million, or $0.30 per share, related to the accelerated vesting under the market sweep provision for all options granted prior to October 1, 2011. The decrease noted above was partially offset by an increase in net income from operations.

Earnings per ~~Share.~~Share. The basic and diluted earnings per share were $2.39 for the fiscal year ended September 30, 2013 and $5.97 per share for the fiscal year ended September 30, 2012. Net income for the fiscal year ended September 30, 2013 of $302.8 million was decreased by dividend equivalent payments of $171.2 million ~~or $3.11 per share,~~ resulting in net income available to common shareholders of $131.5 million. Net income for the fiscal year ended September 30, 2012 of $325.0 million was decreased by dividend equivalent payments of $3.3 million ~~or $0.06 per share,~~ resulting in net income available to common shareholders of $321.7 million. The decrease in earnings per share of $5.97 per share to $2.39 per share is a result of the factors referred to above.

Segment Net Sales. Net sales by segment for the fiscal years ended September 30, 2013 and 2012 were as follows (amounts in millions):

Sales for the Power & Control segment, excluding acquisitions and a retroactive contract pricing adjustment, increased approximately $32 million when compared to the fiscal year ended September 30, 2012. The sales increase was primarily due to an increase in defense sales of approximately $18 million, or an increase of 6.2%, an increase in commercial aftermarket sales of approximately $13 million, or an increase of 4.1%, and an increase in commercial OEM sales of approximately $4 million, or an increase of 3.1%. Acquisition sales totaled $70 million, or a 9.0% increase in segment sales, resulting from the acquisitions of Whippany Actuation and Arkwin in fiscal 2013 and Harco and Aero-Instruments in fiscal 2012. Sales for the fiscal year ended September 30, 2012 include a favorable commercial aftermarket retroactive contract pricing adjustment of approximately $6 million.

Sales for the Airframe segment, excluding acquisitions, the AmSafe distribution business, and OEM retroactive contract pricing adjustments, increased approximately $54 million when compared to the fiscal year ended September 30, 2012. The sales increase was primarily due to an increase in commercial OEM sales of approximately $50 million, or an increase of 14.3%, and an increase in defense sales of approximately $15 million, or an increase of 14.2%, offset by a decline in commercial aftermarket sales of approximately $10

million, or a decrease of 2.6%. The commercial aftermarket comparable sales, particularly in the second half of fiscal 2013 compared to the second half of fiscal 2012, were negatively impacted by non-market items associated with changing past business practices of previously-acquired businesses, changes in distributors and related inventory fluctuations. Acquisition sales for the Airframe segment totaled $83 million, or a 9.8% increase in segment sales, resulting from the acquisitions of Aerosonic in fiscal 2013 and AmSafe in fiscal 2012. The fiscal year ended September 30, 2013 reflects an OEM retroactive contract pricing adjustment of approximately $2 million. The fiscal year ended September 30, 2012 reflects sales of $18.8 million related to the AmSafe distribution business, which was acquired as part of AmSafe on February 15, 2012 and sold on August 16, 2012. The fiscal year ended September 30, 2012 also reflects OEM retroactive contract pricing adjustments of approximately $13 million.

Acquisition sales for the Non-aviation segment totaled $31 million resulting primarily from the non-aviation business of AmSafe acquired in fiscal 2012. Organic sales declined by approximately $11 million.

EBITDA As Defined for the Power & Control segment, excluding acquisitions and a prior year commercial aftermarket retroactive contract pricing adjustment, increased approximately $28 million when compared to the fiscal year ended September 30, 2012 due to increases in defense sales and commercial aftermarket sales. EBITDA As Defined from the acquisitions of Whippany Actuation, Arkwin, Aero-Instruments and Harco was approximately $23 million for the fiscal year ended September 30, 2013, which represented EBITDA As Defined of approximately 33% of the acquisition sales.

EBITDA As Defined for the Airframe segment, excluding acquisitions, pricing adjustments, and the AmSafe distribution business, increased approximately $25 million when compared to the fiscal year ended September 30, 2012. The increase was primarily due to the increases in commercial OEM sales and defense sales partially offset by a decrease in commercial aftermarket sales. EBITDA As Defined from the acquisitions of Aerosonic and AmSafe was approximately $31 million for the fiscal year ended September 30, 2013, which represented EBITDA As Defined of approximately 37% of the acquisition sales. The year ended September 30, 2012 reflects EBITDA As Defined of approximately $13 million relating to prior year OEM retroactive contract pricing adjustments and approximately $3 million relating to the AmSafe distribution business. The year ended September 30, 2013 reflects EBITDA As Defined of approximately $2 million relating to the previously mentioned retroactive contract pricing adjustment.

EBITDA As Defined for the Non-aviation segment from the acquisition of AmSafe was approximately $3 million for the fiscal year ended September 30, 2013. Organic EBITDA declined approximately $4 million due to the organic sales decrease noted above and the mix of products sold in the non-aviation markets.

~~Fiscal year ended September 30, 2012 compared with fiscal year ended September 30, 2011~~

~~Net Sales~~~~. Net organic and acquisition sales and the related dollar and percentage changes for the fiscal years ended September 30, 2012 and 2011 were as follows (amounts in millions):~~

Acquisition sales represent sales of acquired businesses for the period up to one year subsequent to their acquisition dates. The amount of acquisition sales shown in the table above resulted from the acquisitions of McKechnie Aerospace, Talley Actuation and Schneller in fiscal 2011 and Harco, AmSafe and Aero-Instruments in fiscal 2012.

Organic sales for the fiscal year ended September 30, 2012 include favorable commercial OEM retroactive contract pricing adjustments of approximately $13 million and a favorable commercial aftermarket retroactive contract pricing adjustment of approximately $6 million.

Excluding the impact of the retroactive contract pricing adjustments indicated above, commercial OEM sales increased $66.1 million, or an increase of 19.7%, commercial aftermarket sales increased $23.6 million, or an increase of 4.9%, and defense sales increased $30.5 million, or an increase of 8.9%, for the fiscal year ended September 30, 2012.

~~Cost of Sales and Gross Profit~~. Cost of sales increased by $209.7 million, or 38.5%, to $754.5 million for the fiscal year ended September 30, 2012 compared to $544.8 million for the fiscal year ended September 30, 2011. Cost of sales and the related percentage of total sales for the fiscal years ended September 30, 2012 and 2011 were as follows (amounts in millions):

The increase in the dollar amount of cost of sales during the fiscal year ended September 30, 2012 was primarily due to increased volume associated with organic sales growth and the sales from acquisitions partially offset by lower acquisition-related costs as shown in the table above.

Gross profit as a percentage of sales increased by 0.8 percentage points to 55.6% for the fiscal year ended September 30, 2012 from 54.8% for the fiscal year ended September 30, 2011. The dollar amount of gross profit increased by $284.5 million, or 43.0%, for the fiscal year ended September 30, 2012 compared to the comparable period last year due to the following items:

~~Selling and Administrative Expenses.~~Selling and administrative expenses increased by $68.0 million to $201.7 million, or 11.9% of sales, for the fiscal year ended September 30, 2012 from $133.7 million, or 11.1% of sales, for the comparable period last year. Selling and administrative expenses and the related percentage of total sales for the fiscal years ended September 30, 2012 and 2011 were as follows (amounts in millions):

The increase in the dollar amount of selling and administrative expenses during the fiscal year ended September 30, 2012 is primarily due to higher selling and administrative expenses relating to recent acquisitions of approximately $56 million, which was approximately 16% of the acquisition sales. The increase in stock compensation expense is primarily due to an increased level of employees that participate in the Company’s stock compensation plans as a result of acquisitions and also due to higher grant date fair values for our stock options.

~~Amortization of Intangible Assets.~~Amortization of intangible assets increased to $44.2 million for the fiscal year ended September 30, 2012 from $40.3 million for the comparable period last year. The net increase of $3.9 million was primarily due to amortization expense related to the additional identifiable intangible assets recognized in connection with acquisitions during the last twelve months.

~~Refinancing Costs.~~ Refinancing costs were recorded as a result of the refinancing of TransDigm’s entire debt structure in December 2010. The charge of $72.5 million consisted of the premium of $41.9 million paid to redeem our 7³/₄% senior subordinated notes, the write-off of debt issue costs and unamortized note premium and discount of $25.7 million, and the settlement of the interest rate swap agreement and other expenses of $4.9 million.

~~Interest Expense-net.~~Interest expense-net includes interest on outstanding borrowings, amortization of debt issue costs and revolving credit facility fees offset by interest income. Interest expense increased $26.6 million, or 14.4%, to $211.9 million for the fiscal year ended September 30, 2012 from $185.3 for the comparable period last year. The net increase in interest expense-net was primarily due to an increase in the weighted average level of outstanding borrowings, which was approximately $3.44 billion for the fiscal year ended September 30, 2012 and approximately $2.90 billion for the fiscal year ended September 30, 2011 slightly offset by a decrease in the weighted average interest rate during the fiscal year ended September 30, 2012 of 6.2% compared to the weighted average interest rate during the comparable prior period of 6.4%. The increase in borrowings was due to the debt refinancing transactions and the acquisition financing related to McKechnie Aerospace which occurred in December 2010 and the additional term loan facility under the Amendment to our 2011 Credit Facility related to the AmSafe acquisition which occurred in February 2012.

~~Income Taxes.~~Income tax expense as a percentage of income before income taxes was approximately 33.4% for the fiscal year ended September 30, 2012 compared to 33.6% for the fiscal year ended September 30, 2011. The decrease in the effective tax rate was primarily due to non-recurring adjustments in estimated deferred state obligations and the settlement of an IRS audit for the September 30, 2009 and 2010 year ends offset by the additional tax gain from the sale of the AmSafe distribution business.

~~Income from Continuing Operations.~~ Income from continuing operations increased by $172.8 million, or 113.5%, to $325.0 million for the fiscal year ended September 30, 2012 from $152.2 million for the comparable period last year. Income from continuing operations increased due to the factors described above.

~~Income from Discontinued Operations.~~ Income from discontinued operations includes results of operations through the dates of sale of the fastener business and AQS and the after-tax net gain on sales of $19.9 million for the fiscal year ended September 30, 2011.

~~Net Income~~. Net income increased $152.9 million, or 88.8%, to $325.0 million for the fiscal year ended September 30, 2012 compared to net income of $172.1 million for the fiscal year ended September 30, 2011, primarily as a result of the factors referred to above.

~~Earnings per Share.~~ The basic and diluted earnings per share were $5.97 for the fiscal year ended September 30, 2012 and $3.17 per share for the fiscal year ended September 30, 2011. Net income for the fiscal year ended September 30, 2012 of $325.0 million was decreased by dividend equivalent payments of $3.3 million resulting in net income available to common shareholders of $321.7 million. The fiscal year ended September 30, 2011 comprises basic and diluted earnings per share from continuing operations of $2.80 and basic and diluted earnings per share from discontinued operations of $0.37. Net income for the fiscal year ended September 30, 2011 of $172.1 million was decreased by dividend equivalent payments of $2.8 million resulting in net income available to shareholders of $169.3 million. The increase in earnings per share from continuing operations of $2.80 per share to $5.97 per share is due to the increase in income from continuing operations of $172.8 million, which is a result of the factors referred to above.

~~Segment Net Sales~~~~. Net sales by segment for the fiscal years ended September 30, 2012 and 2011 were as follows (amounts in millions):~~

Sales for the Power & Control segment, excluding acquisitions and a commercial aftermarket retroactive contract pricing adjustment, increased approximately $51 million when compared to the fiscal year ended September 30, 2011. The sales increase was primarily due to an increase in defense sales of approximately $30 million, or an increase of 12.0%, an increase in commercial OEM sales of approximately $15 million, or an increase of 13.7%, and an increase in commercial aftermarket sales of approximately $5 million, or an increase of 0.9%. Acquisition sales totaled $50 million, or a 7.5% increase in segment sales, resulting primarily from the acquisition of Harco in fiscal 2012, and to a lesser extent the acquisition of the Talley Actuation business and certain product lines of McKechnie Aerospace in fiscal 2011. Sales for the fiscal year ended September 30, 2012 includes a favorable commercial aftermarket retroactive contract pricing adjustment of approximately $6 million.

Sales for the Airframe segment, excluding acquisitions and retroactive contract pricing adjustments, increased approximately $67 million when compared to the fiscal year ended September 30, 2011. The sales increase was primarily due to an increase in commercial OEM sales of approximately $46 million, or an increase of 21.3%, and an increase in commercial aftermarket sales of approximately $19 million, or an increase of 9.6%. Acquisition sales totaled $259 million, or a 51.2% increase in segment sales, resulting primarily from the acquisition of AmSafe in fiscal 2012 and Schneller in fiscal 2011 and to a lesser extent certain product lines of McKechnie Aerospace in fiscal 2011. Sales during the fiscal year ended September 30, 2012 reflect commercial OEM retroactive contract pricing adjustments of approximately $13 million.

~~The increase in net sales for the Non-aviation segment is primarily due to acquisition sales of $43 million relating to the non-aviation business of AmSafe acquired in fiscal 2012.~~

~~EBITDA As Defined~~~~. EBITDA As Defined by segment for the fiscal years ended September 30, 2012 and 2011 were as follows (amounts in millions):~~

EBITDA As Defined for the Power & Control segment, excluding acquisitions and a commercial aftermarket retroactive contract pricing adjustment, increased approximately $36 million when compared to the fiscal year ended September 30, 2011 due to the increases in defense sales, commercial OEM sales and commercial aftermarket sales. EBITDA As Defined from the acquisitions of Harco, Talley Actuation and certain product lines of McKechnie Aerospace was approximately $20 million for the fiscal year ended September 30, 2012, which represented EBITDA As Defined of approximately 39% of the acquisition sales.

EBITDA As Defined for the Airframe segment, excluding acquisitions and retroactive contract pricing adjustments, increased approximately $41 million when compared to the fiscal year ended September 30, 2011 due to the increases in commercial OEM sales and commercial aftermarket sales. EBITDA as Defined from the acquisitions of AmSafe, Schneller and certain product lines of McKechnie Aerospace was approximately $104 million for the fiscal year ended September 30, 2012, which represented EBITDA As Defined of approximately 40% of the acquisition sales.

~~EBITDA As Defined for the Non-aviation segment increased primarily due to acquisition sales relating to the non-aviation business of AmSafe acquired in fiscal 2012.~~

outstanding as of September 30, ~~2013~~2014 are scheduled for delivery within the next twelve months. Purchase orders may be subject to cancellation or deferral by the customer prior to shipment. The level of unfilled purchase orders at any given date during the year will be materially affected by the timing of the Company’s receipt of purchase orders and the speed with which those orders are filled. Accordingly, the Company’s backlog as of September 30, ~~2013~~2014 may not necessarily represent the actual amount of shipments or sales for any future period.

Although we manufacture a significant portion of our products in the United States, we manufacture some products in Belgium, China, Malaysia, Mexico, Sri Lanka and the United Kingdom. We sell our products in the United States as well as in foreign countries. Although the majority of sales of our products are made to customers ~~including distributors~~(including distributors) located in the United States, our products are ultimately sold to and used by customers, ~~including~~(including airlines and other end users of ~~aircraft,~~aircraft), throughout the world. A number of risks inherent in international operations could have a material adverse effect on our results of operations, including currency fluctuations, difficulties in staffing and managing multi-national operations, general economic and political uncertainties and potential for social unrest in countries in which we operate, limitations on our ability to enforce legal rights and remedies, restrictions on the repatriation of funds, change in trade policies, tariff regulation, difficulties in obtaining export and import licenses and the risk of government financed competition.

Our direct sales to foreign customers were approximately $735.9 million, $572.0 million, ~~$508.8 million,~~ and ~~$305.5~~$508.8 million for fiscal years 2014, 2013 ~~2012~~ and ~~2011,~~2012, respectively. Sales to foreign customers are subject to numerous additional risks, including the impact of foreign government regulations, political uncertainties and differences in business practices. There can be no assurance that foreign governments will not adopt regulations or take other actions that would have a direct or indirect adverse impact on the business or market opportunities of the Company within such governments’ countries. Furthermore, there can be no assurance that the political, cultural and economic climate outside the United States will be favorable to our operations and growth strategy.

Many of the Company’s raw materials and operating expenses are sensitive to the effects of inflation, which could result in changing operating costs. The effects of inflation on the Company’s businesses during the fiscal years 2014, 2013 ~~2012~~ and ~~2011~~2012 were not significant.

We have historically maintained a capital structure comprising a mix of equity and debt financing. We vary our leverage both to optimize our equity return and to pursue acquisitions. We expect to meet our current debt obligations as they come due through internally generated funds from current levels of operations and/or through refinancing in the debt or equity markets prior to the maturity dates of our debt.

We continually evaluate our debt facilities to assess whether they most efficiently and effectively meet the current and future needs of our business. The Company evaluates from time to time the appropriateness of its current leverage, taking into consideration the Company’s debt holders, equity holders, credit ratings, acquisition opportunities and other factors. The Company’s debt leverage ratio, which is computed as total debt divided by EBITDA As Defined for the applicable twelve-month period, has varied widely during the Company’s history, ranging from approximately 3.5 to ~~6.5.~~7.0. Our debt leverage ratio at September 30, ~~2013~~2014 was approximately ~~6.4.~~7.0.

The Company regularly engages in discussions with respect to potential acquisitions and investments. However, there can be no assurance that the Company will be able to consummate an agreement with respect to any future acquisition. The Company’s acquisition strategy may require substantial capital, and no assurance can be given that the Company will be able to raise any necessary funds on acceptable terms or at all. If the Company incurs additional debt to finance acquisitions, total interest expense will increase.

If the Company has excess cash, it may consider methods by which it can provide cash to its debt or equity holders through a dividend, prepayment of indebtedness, repurchase of stock, repurchase of debt or other means. Whether the Company undertakes additional stock repurchases or other aforementioned activities will depend on prevailing market conditions, the Company’s liquidity requirements, contractual restrictions and other factors. The amounts involved may be material. In addition, the Company may issue additional debt if prevailing market conditions are favorable to doing so.

The Company’s ability to make scheduled interest payments on, or to refinance, the Company’s indebtedness, or to fund non-acquisition related capital expenditures and research and development efforts, will depend on the Company’s ability to generate cash in the future. This is subject to general economic, financial, competitive, legislative, regulatory and other factors that are beyond its control. Based on its current levels of operations and absent any disruptive events, management believes that internally generated funds and borrowings available under our revolving loan facility should provide sufficient resources to finance its operations, non-acquisition related capital expenditures, research and development efforts and long-term indebtedness obligations through at least fiscal ~~2014.~~2015. There can be no assurance, however, that the Company’s business will generate sufficient cash flow from operations or that future borrowings will be available to the Company under the senior secured credit facility in an amount sufficient to enable it to pay its indebtedness or to fund its other liquidity needs. The Company may need to refinance all or a portion of its indebtedness on or before maturity. Also, to the extent the Company accelerates its growth plans, consummates acquisitions or has lower than anticipated sales or increases in expenses, the Company may also need to raise additional capital. In particular, increased working capital needs occur whenever the Company consummates acquisitions or experiences strong incremental demand. There can be no assurance that the Company will be able to raise additional capital on commercially reasonable terms or at all.

The Company has not, at this time, determined to change the nature of its debt facilities. However, in the future, the Company may increase its borrowings in connection with acquisitions, if cash flow from operations becomes insufficient to fund current operations or for other short-term cash needs or for stock repurchases or dividends. Our future leverage will also be impacted by the then current conditions of the credit markets.

Operating Activities. The Company generated $541.2 million of net cash from operating activities during fiscal 2014 compared to $470.2 million during fiscal 2013.

On ~~February 28, 2013,~~June 4, 2014, TransDigm Inc. ~~entered into an Amendment and Restatement Agreement (the “Amendment and Restatement Agreement”) in which TransDigm~~ amended and restated its ~~previous~~existing credit ~~facilities. The Amendment and Restatement Agreement provides for a $2,200 million term loan facility (the “Term Loan Facility”), which was fully drawn on~~agreement dated February 28, 2013, by entering into a Second Amended and ~~a $310 million revolving credit facility~~Restated Credit Agreement (the ~~“Revolving Credit Facility” and together with the Term Loan Facility, the “2013~~“2014 Credit Facility”).

The proceeds of the Term Loan Facility were used to repay in full the outstanding term loans under the previous credit facility and the related transaction expenses associated therewith. The Term Loan Facility consists of two tranches of term loans: the tranche B term loans and the tranche C term loans, and the Revolving2014 Credit Facility consists of two tranches: the revolving A commitments and the revolving B commitments. The tranche B term loans consist of $500 million in the aggregate and the tranche C term loans consist of $1,700 million in the aggregate. The tranche B term loans mature on February 14, 2017 and the tranche C term loans mature on February 28, 2020.

On July 1, 2013, in accordance with the terms of the 2013 Credit Facility, TransDigm Inc. entered into an Incremental Term Loan Assumption Agreement (the “Term Loan Assumption Agreement”). The Term Loan Assumption Agreement provides for incremental term loans in the form of additional Tranche C Term Loans in the aggregate principal amount of $900 million (the “Incremental Term Facility”). The Incremental Term Facility was fully drawn on July 1, 2013. The terms and conditions that apply to the ~~Incremental~~Tranche D Term ~~Facility~~Loans, including pricing, are substantially the same as the terms and conditions that apply to the ~~existing tranche C~~other term loans under the ~~2013~~2014 Credit Facility. In addition, the Revolving A Credit Commitments previously available under the credit facility were terminated.

The term loan facilities under the 2014 Credit Facility (the “Term Loan Facility”) now consist of three tranches of term loans—Tranche B Term Loans, Tranche C Term Loans and Tranche D Term Loans.

The revolving A commitments mature on December 6, 2015 and the revolving B commitments~~ mature on February 28, 2018. At September 30, ~~2013,~~2014, the Company had $6.8 million letters of credit outstanding and ~~$303.2~~$413.2 million of borrowings available under the ~~2013~~2014 Credit Facility.

Under the terms of the ~~2013~~2014 Credit Facility, TransDigm is entitled on one or more occasions, subject to the satisfaction of certain conditions, to request additional commitments under the Revolving Credit Facility or additional term loans in the aggregate principal amount of up to ~~$500 million~~$1.0 billion to the extent that existing or new lenders agree to provide such additional term loans. ~~In addition, TransDigm is entitled to convert, subject to certain conditions, the revolving A commitments to revolving B commitments.~~

All of the indebtedness outstanding under the ~~2013~~2014 Credit Facility is guaranteed by TD Group and all of TransDigm’s current and future domestic restricted subsidiaries (other than immaterial subsidiaries). In addition, the obligations of TransDigm and the guarantors under the ~~2013~~2014 Credit Facility are secured ratably in accordance with each lender’s respective revolving and term loan commitments by a first priority security interest in substantially all of the existing and future property and assets, including inventory, equipment, general intangibles, intellectual property, investment property and other personal property (but excluding leasehold interests and certain other assets) of TransDigm and its existing and future domestic restricted subsidiaries (other than immaterial subsidiaries), and a first priority pledge of the capital stock of TransDigm and its subsidiaries (other than foreign subsidiaries and certain domestic subsidiaries, of which 65% of the voting capital stock is pledged).

The interest rates per annum applicable to the loans under the ~~2013~~2014 Credit Facility will be, at TransDigm’s option, equal to either an alternate base rate or an adjusted LIBO rate for one, two, three or six-month (or to the extent agreed to by each relevant lender, nine or twelve-month) interest periods chosen by TransDigm, in each case plus an applicable margin percentage. The adjusted LIBO rate is subject to a floor of .75%. At September 30, ~~2013~~2014 the applicable interest rate was 3.50% on the ~~tranche~~Tranche B ~~term loan~~Term Loan and 3.75% on the ~~tranche~~Tranche C ~~term loan.~~and Tranche D Term Loans.

The Term Loan Facility requires mandatory prepayments of principal based on certain percentages of Excess Cash Flow (as defined in the ~~2013~~2014 Credit Facility), commencing 90 days after the end of each fiscal year, commencing with the fiscal year ending September 30, 2014, subject to certain exceptions. In addition, subject to certain exceptions (including, with respect to asset sales, the reinvestment in productive assets), TransDigm will be required to prepay the loans outstanding under the ~~term loan~~Term Loan facility at 100% of the principal amount thereof, plus accrued and unpaid interest, with the net cash proceeds of certain asset sales and issuance or incurrence of certain indebtedness. In addition, if, prior to ~~February 28,~~December 4, 2014 with respect to Tranche B and Tranche C Term Loans and June 4, 2015 with respect to Tranche D Term Loans, the principal amount of the term loans are (i) prepaid substantially concurrently with the incurrence by TD Group, TransDigm or any its subsidiaries of new bank loans that have an effective yield lower than the yield in effect on the term loans so prepaid or (ii) received by a lender due to a mandatory assignment following the failure of such lender to consent to an amendment of the ~~2013~~2014 Credit Facility that has the effect of reducing the effective interest rate with respect to the term loans, such prepayment or receipt shall be accompanied by a premium of 1.0%.

The ~~2013~~2014 Credit Facility contains certain covenants that limit the ability of TD Group, TransDigm and TransDigm’s restricted subsidiaries to, among other things: (i) incur or guarantee additional indebtedness or issue preferred stock; (ii) pay distributions on, redeem or repurchase capital stock or redeem or repurchase subordinated debt; (iii) make investments; (iv) sell assets; (v) enter into agreements that restrict distributions or other payments from restricted subsidiaries to TransDigm; (vi) incur or suffer to exist liens securing indebtedness; (vii) consolidate, merge or transfer all or substantially all of their assets; and (viii) engage in transactions with affiliates.

At September 30, ~~2013,~~2014, three forward-starting interest rate swap agreements were in place to swap variable rates on the ~~2013~~2014 Credit Facility for a fixed rate based on an aggregate notional amount of $353 million. These interest rate swap ~~agreements~~agreement converted the variable interest rate on the aggregate notional amount of the ~~2013~~2014 Credit Facility to a fixed rate of 5.17% (2.17% plus the 3% margin percentage) through June 30, 2015.

On July 16, 2013, the Company entered into three forward-starting interest rate swap agreements beginning September 30, 2014 to hedge the variable interest rates on the ~~2013~~2014 Credit Facility for a fixed rate based on an aggregate notional amount of $1.0 billion through June 30, 2019. These forward-starting interest rate swap agreements will effectively convert the variable interest rate on the aggregate notional amount of the ~~2013~~2014 Credit Facility to a fixed rate of 5.4% (2.4% plus the 3% margin percentage) over the term of the interest rate swap agreements.

On July 24, 2014, the Company entered into five forward-starting interest rate swap agreements beginning March 31, 2016 to hedge the variable interest rates on the 2014 Credit Facility for a fixed rate based on an aggregate notional amount of $750 million through June 30, 2020. These forward-starting interest rate swap agreements will effectively convert the variable interest rate on the aggregate notional amount of the 2014 Credit Facility to a fixed rate of 5.8% (2.8% plus the 3% margin percentage) over the term of the interest rate swap agreements.

The ~~2021 Notes, 2020 Notes and the 2018~~ Notes are structurally subordinated to all of the liabilities of TD Group’s non-guarantor subsidiaries. The ~~2021 Notes, 2020 Notes and the 2018~~ Notes contain many of the restrictive covenants included in the ~~2013~~2014 Credit Facility. TransDigm is in compliance with all the covenants contained in the ~~2021 Notes, 2020 Notes and 2018~~ Notes.

The credit facility and the ~~Indentures~~indentures governing the Notes (the “Indentures”) contain restrictive covenants that, among other things, limit the incurrence of additional indebtedness, the payment of dividends, transactions with affiliates, asset sales, acquisitions, mergers and consolidations, liens and encumbrances, and prepayments of other indebtedness. In addition, if the total amount of revolving loans and letters of credit exceeds 25% of the aggregate revolving commitment, the credit facility requires that the Company meet a net debt to EBITDA As Defined ratio, on a pro forma basis. A breach of any of the covenants or an inability to comply with the required leverage ratio could result in a default under the credit facilities or the Indentures. If any such default occurs, the lenders under the credit facilities and the holders of the ~~2018 Notes, 2020 Notes and 2021~~ Notes may elect to declare all outstanding borrowings, together with accrued interest and other amounts payable thereunder, to be immediately due and payable. The lenders under the credit facilities also have the right in these circumstances to terminate any commitments they have to provide further borrowings. In addition, following an event of default under the credit facilities, the lenders thereunder will have the right to proceed against the collateral granted to them to secure the debt, which includes our available cash, and they will also have the right to prevent us from making debt service payments on the ~~2018 Notes, 2020 Notes~~Notes.

During the quarter ended December 28, 2013, the Company established a trade receivables securitization facility (the “Securitization Facility”). The Securitization Facility effectively increases the Company’s borrowing capacity by up to $225 million depending on the amount of trade accounts receivable, and ~~2021 Notes.~~matures on August 7, 2015. The Company uses the proceeds from the securitization program as an alternative to other forms of debt, effectively reducing borrowing costs. As of September 30, 2014, the Company has borrowed $200 million under the Securitization Facility.

Assumes that the variable interest rate on our tranche B borrowings under our senior secured credit facility remains constant at 3.5% and the tranche C borrowings under our senior secured credit facility remains constant at 3.75%. In addition, interest payments include the impact of the 5.17% interest rate fixed through our forward-starting swap agreements from December 31, 2012 through June 30, 2015 on an aggregate notional amount of $353 million, ~~and~~ the impact of the ~~5.42%~~5.4% interest rate fixed through our forward-starting swap agreements from September ~~31,~~30, 2014 through June 30, 2019 on an aggregate notional amount of $1.0 billion, and the impact of the 5.8% interest rate fixed through our forward-starting swap agreements from March 31, 2016 through June 30, 2020 on an aggregate notional amount of $750 million.

In addition to the contractual obligations set forth above, the Company incurs capital expenditures for the purpose of maintaining and replacing existing equipment and facilities and, from time to time, for facility expansion. Capital expenditures totaled approximately $34.1 million, $35.5 million, ~~$25.2 million,~~ and ~~$18.0~~$25.2 million during fiscal 2014, 2013, ~~2012,~~ and fiscal ~~2011,~~2012, respectively. The Company expects its capital expenditures in fiscal ~~2014~~2015 to be between ~~$40~~$60 million and ~~$45 million and such expenditures are projected to increase moderately thereafter.~~$65 million.

In ~~June 2011,~~May 2014, the Financial Accounting Standards Board (“FASB”) issued ~~authoritative accounting guidance included~~Accounting Standards Update (“ASU”) 2014-09 which creates a new topic in the Accounting Standards Codification (“ASC”) Topic ~~220,~~606, “~~Comprehensive Income~~Revenue From Contracts With Customers.”. In addition to superseding and replacing nearly all existing U.S. GAAP revenue recognition guidance, including industry-specific guidance, ASC 606 establishes a new control-based revenue recognition model; changes the basis for deciding when revenue is recognized over time or at a point in time; provides new and more detailed guidance on specific topics; and expands and improves disclosures about revenue. In addition, ASU 2014-09 adds a new Subtopic to the Codification, ASC 340-40, “Other Assets and Deferred Costs: Contracts with Customers,” ~~This~~to provide guidance ~~eliminates the option~~on costs related to ~~report other comprehensive income~~obtaining a contract with a customer and ~~its components~~costs incurred in fulfilling a contract with a customer that are not in the ~~statement~~scope of ~~changes in equity. Companies can elect to present items of net income and other comprehensive income in one continuous statement or in two separate, but consecutive, statements.~~another ASC Topic. The ~~Company adopted the presentation guidance during the first quarter of fiscal 2013 and has elected to present two separate consecutive statements.~~

~~In February 2013, FASB issued authoritative accounting guidance included in ASC Topic 220, “~~~~Comprehensive Income~~.” This guidance requires all U.S. public companies to report the effect of items reclassified out of accumulated other comprehensive income on the respective line items of net income, net of tax, either on the face of the financial statements where net income is presented or in a tabular format in the notes to the financial statements. This presentation guidance is effective for the Company ~~on October 1, 2013. The adoption of this guidance~~for annual reporting periods, including interim periods therein, for the year ending September 30, 2018. Early application is not ~~expected to~~permitted. The Company is currently evaluating the impact that the update will have ~~a material impact~~ on ~~the Company’s~~its financial position, results of operations, cash flows and financial ~~condition.~~statement disclosures.

Separate financial statements of TransDigm Inc. are not presented since TD Group has no operations or significant assets separate from its investment in TransDigm Inc. and since the ~~2018 Notes, 2020 Notes and the 2021~~ Notes are guaranteed by TD Group and all direct and indirect domestic restricted subsidiaries of TransDigm Inc. TransDigm Inc.’s immaterial wholly owned foreign subsidiaries are not obligated to guarantee the ~~2018 Notes, 2020 Notes and the 2021~~ Notes.

Our main exposure to market risk relates to interest rates. Our financial instruments that are subject to interest rate risk principally include fixed-rate and floating-rate long-term debt. At September 30, ~~2013,~~2014, we had borrowings under our ~~2013~~2014 Credit Facility of ~~$3.08~~$3.87 billion that were subject to interest rate risk. Borrowings under our ~~2013~~2014 Credit Facility bear interest, at our option, at a rate equal to either an alternate base rate or an adjusted LIBO rate for a one-, two-, three- or six-month (or to the extent available to each lender, nine- or twelve-month) interest period chosen by us, in each case, plus an applicable margin percentage. Accordingly, the Company’s cash flows and earnings will be exposed to the market risk of interest rate changes resulting from variable rate borrowings under our ~~2013~~2014 Credit Facility. The effect of a hypothetical one percentage point increase in interest rates would increase the annual interest costs under our ~~2013~~2014 Credit Facility by approximately ~~$30.8~~$38.7 million based on the amount of outstanding borrowings at September 30, ~~2013.~~2014. The weighted average interest rate on the ~~$3.08~~$3.87 billion of borrowings under our 2013 Credit Facility on September 30, ~~2013~~2014 was 3.8%.

At September 30, ~~2013,~~2014, three forward-starting interest rate swap agreements were in place to swap variable rates on the ~~2013~~2014 Credit Facility for a fixed rate based on an aggregate notional amount of $353 million. These interest rate swap agreement converted the variable interest rate on the aggregate notional amount of the ~~2013~~2014 Credit Facility to a fixed rate of 5.17% (2.17% plus the 3% margin percentage) through June 30, 2015.

The fair value of the ~~$3.08~~$3.87 billion aggregate principal amount of borrowings under our ~~2013~~2014 Credit Facility is exposed to the market risk of interest rates. The estimated fair value of such term loan approximated ~~$3.07~~$3.82 billion at September 30, ~~2013~~2014 based upon information provided to the Company from its agent under the

~~2013~~ 2014 Credit Facility. The fair value of ~~the $1.60 billion aggregate principal amount of~~ our ~~2018 Notes,~~ $0.55 billion 2020 Notes, ~~and~~ our $0.50 billion 2021 Notes, ~~due~~our $1.15 billion 2022 Notes and our $1.2 billion 2024 Notes are exposed to the market risk of interest rate changes. The estimated fair value of the ~~2018 Notes approximated $1.71 billion, the estimated fair value of the~~ 2020 Notes approximated ~~$0.54~~$0.53 billion, ~~and~~ the estimated fair value of the 2021 Notes approximated ~~$0.54~~$0.53 billion, the estimated fair value of the 2022 Notes approximated $1.12 billion and the estimated fair value of the 2024 Notes approximated $1.18 billion at September 30, ~~2013~~2014 based upon quoted market rates.

The information required by this Item is contained on pages F-1 through ~~F-40~~F-39 of this Report.

As of September 30, ~~2013,~~2014, TD Group carried out an evaluation, under the supervision and with the participation of TD Group’s management, including its Chief Executive Officer (Principal Executive Officer) and Chief Financial Officer (Principal Financial Officer), of the effectiveness of the design and operation of TD Group’s disclosure controls and procedures. Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that TD Group’s disclosure controls and procedures are effective to ensure that information required to be disclosed by TD Group in the reports it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified by the Securities and Exchange Commission’s rules and forms, and that such information is accumulated and communicated to TD Group’s management, including its Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, TD Group’s management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management necessarily was required to apply its judgment in designing and evaluating the controls and procedures.

The management of TD Group is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Exchange Act Rule 13a-15(f). Using criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (1992 framework) (COSO) in Internal Control-Integrated Framework, TransDigm’s management assessed the effectiveness of the Company’s internal control over financial reporting as of September 30, ~~2013.~~2014. Based on our assessment, management concluded that the Company’s internal control over financial reporting was effective as of September 30, ~~2013.~~2014.

During fiscal ~~2013,~~2014, we completed the acquisitions of ~~Whippany Actuation, Arkwin~~Airborne and ~~Aerosonic.~~EME. The results of operations are included in our consolidated financial statements from the date of acquisition. As permitted by the Securities and Exchange Commission, we have elected to exclude ~~Whippany Actuation, Arkwin~~Airborne and ~~Aerosonic~~EME from our assessment of the effectiveness of our internal control over financial reporting as of September 30, ~~2013.~~2014. Total assets and net sales of ~~Whippany Actuation, Arkwin~~Airborne and ~~Aerosonic~~EME represented approximately ~~9% and 3%, respectively,~~6% of each of our total assets and net sales as reported in our consolidated financial statements for fiscal ~~2013.~~2014.

The Company’s independent auditors, Ernst & Young LLP, have issued an audit report on the effectiveness of internal control over financial reporting of the Company as of September 30, ~~2013.~~2014. This report is included herein.

During ~~2013~~2014 we acquired ~~Whippany Actuation, Arkwin~~Airborne and ~~Aerosonic~~EME which operated under their own set of systems and internal controls. We are currently maintaining those systems and much of the control environment until we are able to incorporate their processes into our own systems and control environment. We currently expect to complete the incorporation of their operations into our systems and control environment in fiscal ~~2014.~~2015. There were no other changes to our internal controls over financial reporting that could have a material effect on our financial reporting during fiscal ~~2013.~~2014.

We have audited TransDigm Group Incorporated’s internal control over financial reporting as of September 30, ~~2013,~~2014, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway ~~Commissionin 1992~~Commission (1992 framework) (the COSO criteria). TransDigm Group Incorporated’s management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the company’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with policies and procedures may deteriorate.

As indicated in the accompanying Management’s Report on Internal Control Over Financial Reporting, management’s assessment of and conclusion on the effectiveness of internal control over financial reporting did not include the internal controls of ~~Whippany Actuation Systems LLC, Arkwin Industries,~~Airborne Global Inc. and ~~Aerosonic LLC,~~Elektro-Metall Export GmbH, which are included in the ~~2013~~2014 consolidated financial statements of TransDigm Group Incorporated and constituted 9%6% of total assets as of September 30, ~~2013 and3%~~2014 and ~~(1)%~~6% and 0.5% of revenues and net income, respectively, for the year then ended. Our audit of internal control over financial reporting ~~ofTransDigm~~of TransDigm Group Incorporated also did not include an evaluation of the internal control over financial reporting of ~~Whippany Actuation Systems LLC, Arkwin Industries,~~Airborne Global Inc. and ~~Aerosonic LLC.~~Elektro-Metall Export GmbH.

Pursuant to the requirements of Section 13 or 15(d) of the Securities Exchange Act of 1934, the registrant has duly caused this Report to be signed on its behalf by the undersigned, thereunto duly authorized on November ~~15, 2013.~~14, 2014.

Pursuant to the requirements of the Securities Exchange Act of 1934, this Report has been signed below by the following persons on behalf of the registrant and in the capacities and as of the dates indicated.

We have audited the accompanying consolidated balance sheets of TransDigm Group Incorporated as of September 30, ~~2013~~2014 and ~~2012,~~2013, and the related consolidated statements of income, comprehensive income, stockholders’ (deficit) equity, and cash flows for each of the three years in the period ended September 30, ~~2013.~~2014. Our audits also included the financial statement schedule listed in the Index at Item 15(a). These financial statements and schedule are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements and schedule based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of TransDigm Group Incorporated at September, 30, ~~2013~~2014 and ~~2012,~~2013, and the consolidated results of its operations and its cash flows for each of the three years in the period ended September 30, ~~2013,~~2014, in conformity with U.S. generally accepted accounting principles. Also, in our opinion, the related financial statement schedule, when considered in relation to the basic financial statements taken as a whole, presents fairly in all material respects the information set forth therein.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), TransDigm Group Incorporated’s internal control over financial reporting as of September 30, ~~2013,~~2014, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission ~~in 1992and~~(1992 framework) and our report dated November ~~15, 2013~~14, 2014, expressed an unqualified opinion thereon.

The Company accounted for the acquisitions using the acquisition method and included the results of operations of the acquisitions in its consolidated financial statements from the effective date of each acquisition. The Company is in the process of obtaining a third-party valuation of certain tangible and intangible assets of ~~Whippany Actuation, Arkwin~~EME and ~~Aerosonic;~~Airborne; therefore, the values attributed to those acquired assets in the consolidated financial statements are subject to adjustment. Pro forma net sales and results of operations for the acquisitions, had they occurred at the beginning of the applicable fiscal year ended September 30, ~~2013~~2014 or ~~2012,~~2013, are not significant and, accordingly, are not provided.

The acquisitions strengthen and expand the Company’s position to design, produce and supply highly-engineered proprietary aerospace components in niche markets with significant aftermarket content and provide opportunities to create value through the application of our three core value-driven operating strategies (obtaining profitable new business, improving our cost structure, and providing highly engineered value-added products to customers). The purchase price paid for each acquisition reflects the current earnings before interest, taxes,

depreciation and amortization (EBITDA) and cash flows, as well as, the future EBITDA and cash flows expected to be generated by the business, which are driven in most cases by the recurring aftermarket consumption over the life of a particular aircraft, estimated to be approximately 3025-30 years.

Basis of Presentation and Consolidation—The accompanying consolidated financial statements were prepared in conformity with generally accepted accounting principles in the United States (“GAAP”) and include the accounts of TD Group and subsidiaries. All significant intercompany balances and transactions have been eliminated.

Revenue Recognition and Related Allowances—Revenue is recognized from the sale of products when title and risk of loss passes to the customer, which is generally at the time of shipment. Substantially all product sales are made pursuant to firm, fixed-price purchase orders received from customers. Provisions for estimated returns, uncollectible accounts and the cost of repairs under contract warranty provisions are provided for in the same period as the related revenues are recorded and are principally based on historical results modified, as appropriate, by the most current information available. Due to uncertainties in the estimation process, it is possible that actual results may vary from the estimates.

Shipping and Handling Costs—Shipping and handling costs are included in cost of sales in the Consolidated Statements of Income.

Research and Development Costs—The Company expenses research and development costs as incurred and classifies such amounts in selling and administrative expenses. The expense recognized for research and development costs for the years ended September 30, 2014, 2013 ~~2012~~ and ~~2011~~2012 was approximately $42.3 million, $32.1 million, ~~$27.9 million,~~ and ~~$19.3~~$27.9 million, respectively.

Cash Equivalents—The Company considers all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents.

Allowance for Uncollectible Accounts—The Company reserves for amounts determined to be uncollectible based on specific identification of losses and estimated losses based on historical experience. The allowance also

incorporates a provision for the estimated impact of disputes with customers. The determination of the amount of the allowance for doubtful accounts is subject to significant levels of judgment and estimation by management. If circumstances change or economic conditions deteriorate or improve, the allowance for doubtful accounts could increase or decrease.

Inventories—Inventories are stated at the lower of cost or market. Cost of inventories is determined by the average cost and the first-in, first-out (FIFO) methods for all locations except CEF Industries, LLC, which determines the cost of inventories using the last-in, first-out (LIFO) method. ~~Approximately~~Less than 4% of the inventory was valued under the LIFO method at September 30, ~~2013.~~2014. Provision for potentially obsolete or slow-moving inventory is made based on management’s analysis of inventory levels and future sales forecasts. In accordance with industry practice, all inventories are classified as current assets even though a portion of the inventories may not be sold within one year.

Property, Plant and Equipment—Property, plant and equipment are stated at cost. Depreciation is computed using the straight-line method over the following estimated useful lives: land improvements from 10 to 20 years, buildings and improvements from 5 to 30 years, machinery and equipment from 2 to 10 years and furniture and fixtures from 3 to 10 years.

Property, plant and equipment is assessed for potential impairment whenever indicators of impairment are present by determining whether the carrying value of the property can be recovered through projected,

undiscounted cash flows from future operations over the property’s remaining estimated useful life. Any impairment recognized is the amount by which the carrying amount exceeds the fair value of the asset.

Debt Issue Costs, Premiums and Discounts—The cost of obtaining financing as well as premiums and discounts are amortized using the effective interest method over the terms of the respective obligations/securities.

Intangible Assets—Intangible assets consist of identifiable intangibles acquired or recognized in accounting for the acquisitions (trademarks, trade names, technology, order backlog and other intangible assets) and goodwill. Goodwill and intangible assets that have indefinite useful lives (trademarks and trade names) are subject to annual impairment testing. Management determines fair value using a discounted future cash flow analysis or other accepted valuation techniques. The Company performs an annual impairment test for goodwill and other intangible assets as of the first day of the fourth fiscal quarter of each year, or more frequently, if an event occurs or circumstances change that would more likely than not reduce fair value below current value.

A two-step impairment test is used to identify potential goodwill impairment. The first step of the goodwill impairment test, used to identify potential impairment, compares the fair value of a reporting unit (as defined) with its carrying amount, including goodwill. If the fair value of the reporting unit exceeds its carrying amount, goodwill is not considered impaired, and the second step of the goodwill impairment test is unnecessary. The second step measures the amount of impairment, if any, by comparing the carrying value of the goodwill associated with a reporting unit to the implied fair value of the goodwill derived from the estimated overall fair value of the reporting unit and the individual fair values of the other assets and liabilities of the reporting unit.

The impairment test for indefinite lived intangible assets consists of a comparison between their fair values and carrying values. If the carrying amounts of intangible assets that have indefinite useful lives exceed their fair values, an impairment loss will be recognized in an amount equal to the sum of any such excesses.

The Company assesses the recoverability of its amortizable intangible assets only when indicators of impairment are present by determining whether the amortization over their remaining lives can be recovered through projected, undiscounted cash flows from future operations. Amortization of amortizable intangible assets is computed using the straight-line method over the following estimated useful lives: technology from 20 to 22 years, order backlog over one year, and other intangible assets over 20 years.

Stock Option Plans—The Company records stock-based compensation measured using the fair value method of accounting. Compensation expense is recorded over the vesting periods of the options. For options subject to accelerated vesting under the “market sweep” provision, additional stock compensation expense is recorded representing costs that would have been recognized over the remaining requisite service period of the award when the market condition is met.

Income Taxes—The Company accounts for income taxes using an asset and liability approach. Deferred taxes are recorded for the difference between the book and tax basis of various assets and liabilities. A valuation allowance is provided when it is more likely than not that some or all of a deferred tax asset will not be realized.

Contingencies—During the ordinary course of business, the Company is from time to time threatened with, or may become a party to, legal actions and other proceedings. While the Company is currently involved in certain legal proceedings, it believes the results of these proceedings will not have a material adverse effect on its financial condition, results of operations, or cash flows.

~~Discontinued Operations~~—During the year ended September 30, 2011, the Company sold, for aggregate cash proceeds of $271.4 million, two businesses which had been acquired as part of the McKechnie Aerospace acquisition and accounted for the sales as discontinued operations. Aggregate net sales of $24.1 million and losses from discontinued operations of $2.1 million were recognized during the period from the date of the McKechnie Aerospace acquisition through the respective dates of sale of the businesses. The consolidated statement of income for the year ended September 30, 2011 includes income from discontinued operations, net of tax, of $19.9 million, comprising the aggregate net after-tax gain of $22.0 million and the losses from discontinued operations of $2.1 million.

Estimates—The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Comprehensive Income (Loss)—The term “comprehensive income (loss)” represents the change in stockholders’ equity from transactions and other events and circumstances resulting from non-stockholder sources. The Company’s accumulated other comprehensive income or loss, consisting principally of fair value adjustments to its interest rate swap agreements (net of tax), cumulative foreign currency translation adjustments and pension liability adjustments (net of tax), is reported separately in the accompanying consolidated statements of comprehensive income.

Foreign Currency Translation and Transactions—The assets and liabilities of subsidiaries located outside the United States are translated into U.S. dollars at the rates of exchange in effect at the balance sheet dates. Revenue and expense items are translated at the average exchange rates prevailing during the period. Gains and losses resulting from foreign currency transactions are recognized currently in income, and those resulting from translation of financial statements are accumulated as a separate component of other comprehensive income (loss) for the period. Foreign currency gains or losses recognized currently in income from changes in exchange rates were not material to our results of operations.

Earnings per Share—Earnings per share information is determined using the two-class method, which includes the weighted-average number of common shares outstanding during the period and other securities that participate in dividends (“participating securities”). Our vested stock options are considered “participating securities” because they include non-forfeitable rights to dividends. In applying the two-class method, earnings are allocated to both common stock shares and participating securities based on their respective weighted-average shares outstanding for the period. Diluted earnings per share information may include the additional effect of other securities, if dilutive, in which case the dilutive effect of such securities is calculated using the treasury stock method.

In ~~June 2011,~~May 2014, the Financial Accounting Standards Board (“FASB”) issued ~~authoritative accounting guidance included~~Accounting Standards Update (“ASU”) 2014-09 which creates a new topic in the Accounting Standards Codification (“ASC”) Topic ~~220,~~606, “~~Comprehensive Income~~Revenue From Contracts With Customers.”. In addition to superseding and replacing nearly all existing U.S. GAAP revenue recognition guidance, including industry-specific guidance, ASC 606 establishes a new control-based revenue recognition model; changes the basis for deciding when revenue is recognized over time or at a point in time; provides new and more detailed guidance on specific topics; and expands and improves disclosures about revenue. In addition, ASU 2014-09 adds a new Subtopic to the Codification, ASC 340-40, “Other Assets and Deferred Costs: Contracts with Customers,” ~~This~~to provide guidance ~~eliminates the option~~on costs related to ~~report other comprehensive income~~obtaining a contract with a customer and ~~its components~~costs incurred in fulfilling a contract with a customer that are not in the ~~statement~~scope of ~~changes in equity. Companies can elect to present items of net income and other comprehensive income in one continuous statement or in two separate, but consecutive, statements.~~another ASC Topic. The ~~Company adopted the presentation guidance during fiscal 2013 and has elected to present two separate consecutive statements.~~

~~In February 2013, the FASB issued authoritative accounting guidance included in ASC Topic 220, “~~~~Comprehensive Income~~.” This guidance requires all U.S. public companies to report the effect of items reclassified out of accumulated other comprehensive income on the respective line items of net income, net of tax, either on the face of the financial statements where net income is presented or in a tabular format in the notes to the financial statements. This presentation guidance is effective for the Company ~~on October 1, 2013. The adoption of this guidance~~for annual reporting periods, including interim periods therein, for the year ending September 30, 2018. Early application is not ~~expected to~~permitted. The Company is currently evaluating the impact that the update will have ~~a material impact~~ on ~~the Company’s~~its financial position, results of operations, cash flows and financial ~~condition.~~statement disclosures.

The Non-aviation segment includes operations that primarily develop, produce and market products fornon-aviation markets. Major product offerings include seatbelts and safety restraints for ground transportation applications, mechanical/electro-mechanical actuators and controls for space applications, and refueling systems for heavy equipment used in mining, construction and other industries. Primary customers of this segment are off road vehicle suppliers and subsystem suppliers, child restraint system suppliers, satellite and space system suppliers and manufacturers of heavy equipment used in mining, construction and other industries.

The primary measurement used by management to review and assess the operating performance of each segment is EBITDA As Defined. The Company defines EBITDA As Defined as earnings before interest, taxes, depreciation and amortization plus certain non-operating items including refinancing costs, acquisition-related

costs, transaction-related costs and non-cash compensation charges incurred in connection with the Company’s stock option plans. Acquisition-related costs represent accounting adjustments to inventory associated with acquisitions of businesses and product lines that were charged to cost of sales when the inventory was sold; costs incurred to integrate acquired businesses and product lines into the Company’s operations, facility relocation costs and other acquisition-related costs; transaction related costs comprising deal fees; legal, financial and tax diligence expenses and valuation costs that are required to be expensed as incurred and other acquisition accounting adjustments.

EBITDA As Defined is not a measurement of financial performance under GAAP. Although ~~we use~~the Company uses EBITDA As Defined to assess the performance of ~~our~~its business and for various other purposes, the use of this non-GAAP financial measure as an analytical tool has limitations, and ~~you~~it should not ~~consider it~~be considered in isolation or as a substitute for analysis of ~~our~~the Company’s results of operations as reported in accordance with GAAP.

The Company’s segments are reported on the same basis used internally for evaluating performance and for allocating resources. The accounting policies for each segment are the same as those described in the summary of significant accounting policies in the Company’s consolidated financial statements. Intersegment sales and transfers are recorded at values based on market prices, which creates intercompany profit on intersegment sales or transfers that is eliminated in consolidation. Intersegment sales were insignificant for the ~~fiscal years ended September 30, 2013, 2012 and 2011.~~periods presented below.

The Company’s sales principally originate from the United States, and the Company’s long-lived assets are principally located in the United States.

The Company’s stock compensation plans are designed to assist the Company in attracting, retaining, motivating and rewarding key employees, directors or consultants, and promoting the creation of long-term value for stockholders by closely aligning the interests of these individuals with those of the Company’s stockholders. The Company’s stock compensation plans provide for the granting of stock options, restricted stock and other stock-based incentives.

~~The following table shows the~~Non-cash stock compensation expense recognized by the Company ~~for stock-based compensation (in thousands):~~during the years ended September 30, 2014, 2013 and 2012 was $26.3 million, $48.9 million and $22.2 million, respectively.

During the year ended September 30, 2014, the Company recorded additional stock compensation expense of $6.4 million representing costs that would have been recognized over the remaining requisite service period of the award for options granted in fiscal 2012 that became fully vested under the market sweep provision, as discussed further below. During June 2013, a total of 2,409,420 unvested options granted prior to October 1, 2011 with a weighted-average exercise price per option of $58.35 became fully vested under the market sweep provision. Due to the accelerated vesting, the Company recorded additional stock compensation expense of $24.5 million representing costs that would have been recognized over the remaining requisite service period of the ~~award for options granted prior to October 1, 2011 that became fully vested under the market sweep provision, as discussed further below.~~award.

The weighted-average grant date fair value of options granted during the fiscal years ended September 30, 2014, 2013 and 2012 was $57.53, $45.53 and ~~2011 was $45.53,~~ $43.23, ~~and $33.51,~~ respectively.

Compensation expense is recognized based upon probability assessments of awards that are expected to vest in future periods. Such probability assessments are subject to revision and, therefore, unrecognized compensation expense is subject to future changes in estimate. As of September 30, ~~2013,~~2014, there was approximately ~~$22.3~~$33.1 million of total unrecognized compensation expense related to non-vested awards expected to vest, which is expected to be recognized over a weighted-average period of ~~three~~two years.

The fair value of the Company’s employee stock options was estimated at the date of grant using aBlack-Scholes-Merton option-pricing model with the following weighted average assumptions for all options granted during the fiscal years ended:


	Fiscal Years Ended September 30,			Fiscal Years Ended September 30,
	2013	2012	2011	2014	��	2013	2012
Risk-free interest rate	0.84% to 1.00%	1.10% to 1.50%	1.67% to 2.53%	1.71% to 2.03%		0.84% to 1.00%	1.10% to 1.50%
Expected life of options	6 years	6 years	6 years	6 years		6 years	6 years
Expected dividend yield of stock	—	—	—	—		—	—
Expected volatility of stock	35%	40%	40%	35%		35%	40%

The risk-free interest rate is based upon the Treasury bond rates as of the grant date. The average expected life of stock-based awards is based on ~~vesting schedules and contractual terms.~~the Company’s actual historical exercise experience. Expected volatility of stock was calculated using a rate based upon the historical volatility of both TransDigm’s common stock and the stock of publicly traded companies in the Company’s peer group in the aerospace industry. Notwithstanding the special cash dividends paid in October 2012, ~~and~~ July 2013 and June 2014, the Company historically has not paid regular cash dividends and does not anticipate paying regular cash dividends in future periods; thus, no dividend rate assumption is used.

The total fair value of options vested during fiscal years ended September 30, 2014, 2013, and 2012 ~~and 2011~~ was $23.6 million, $63.9 million and $11.4 million, ~~and $7.8 million,~~ respectively.

In July 2014, the board of directors of TD Group adopted a new stock option plan, which was subsequently approved by stockholders on October 2, 2014. The 2014 stock option plan permits TD Group to award our key employees, directors or consultants stock options. The total number of shares of TD Group common stock reserved for issuance or delivery under the 2014 stock option plan is 5,000,000, subject to adjustment in the event of any stock dividend or split, reorganization, recapitalization, merger, share exchange or any other similar corporate transaction or event.

In conjunction with the consummation of the initial public offering, a 2006 stock incentive plan was adopted by TD Group. In July 2008 and March 2011, the plan was amended to increase the number of shares available for issuance thereunder. TD Group has reserved 8,119,668 shares of its common stock for issuance to key employees, directors or consultants under the plan. Awards under the plan may be in the form of options, restricted stock or other stock-based awards. Options granted under the plan will expire no later than the tenth anniversary of the applicable date of grant of the options, and will have an exercise price of not less than the fair market value of our common stock on the date of grant. Restricted stock granted under the plan vests over three years.

In connection with the $12.85 per share special cash dividend paid in November 2012, in order to take into account the earlier return of capital, the TD Group compensation committee adjusted the market-based vesting features in outstanding options pursuant to the authority granted to the committee under the TD Group stock

incentive plan. Under this “market sweep” provision, unvested options granted prior to October 1, 2011 would accelerate and become fully vested if the closing price of the Company’s common stock exceeded $147.15 per share (originally $160 per share) on any 60 trading days during any consecutive 12-month period commencing March 1, 2013.

In addition, in connection with the $12.85 per share special cash dividend paid in November 2012 and the $22.00 per share special cash dividend paid in July 2013, in order to take into account the earlier return of capital, the TD Group compensation committee adjusted the market-based vesting features in outstanding options pursuant to the authority granted to the committee under the TD Group stock incentive plan. Under this “market sweep” provision, unvested options granted in fiscal 2012 would accelerate and become fully vested if the closing price of the Company’s common stock exceeded $135.15 per share (originally $170 per share) on any 60 trading days during any consecutive 12-month period commencing two years from the date of grant. Options granted in fiscal 2013 and 2014 do not contain such accelerated vesting provision.

During June 2013, a total of 2,409,420 unvested options granted prior to October 1, 2011 with a weighted-average exercise price per option of $58.35 became fully vested under the market sweep provision. Due to the accelerated vesting, the Company recorded additional stock compensation expense of $24.5 million representing costs that would have been recognized over the remaining requisite service period of the award.

In addition to shares issued pursuant to options exercised, during the fiscal year ended September 30, ~~2013, 713~~2014, 332 shares of common stock were issued with a weighted-average grant date fair value of ~~$146.37~~$179.53 as payment to directors in lieu of cash.

Performance Vested Stock Options—All of the options granted through September 30, ~~2013~~2014 under the 2006 stock incentive plan have been pursuant to an equity incentive program adopted by the Company in 2008. Under the 2008 equity incentive program, all of the options granted will vest based on the Company’s achievement of established operating performance goals. The following table summarizes the activity, pricing and other information for the Company’s performance vested stock-based award activity during the fiscal year ended September 30, ~~2013:~~2014:

Certain executives and key employees of the Company were granted stock options under TD Group’s 2003 stock option plan. Upon the closing of the acquisition of the Company by Warburg Pincus in 2003, certain employees rolled over certain then-existing options to purchase shares of common stock of TransDigm Holdings. These employees were granted rollover options to purchase an aggregate of 3,870,152 shares of common stock of TD Group (after giving effect to the 149.60 for 1.00 stock split effected on March 14, 2006). All rollover options granted were fully vested on the date of grant. In addition to shares of common stock reserved for issuance upon the exercise of rollover options, an aggregate of 5,469,301 shares of TD Group’s common stock were reserved for issuance upon the exercise of new management options. In general, approximately 20% of all new management options vested based on employment service or a change in control. These time vested options had a

graded vesting schedule of up to four years. Approximately 80% of all new management options vested (i) based upon the satisfaction of specified performance criteria, which is annual and cumulative EBITDA As Defined targets through 2008, or (ii) upon the occurrence of a change in control if the Investor Group (defined as Warburg Pincus and the other initial investors in TD Group) received a minimum specified rate of return. Unless terminated earlier, the options expire ten years from the date of grant.

TD Group has reserved a total of 9,339,453 shares of its common stock for issuance to the Company’s employees under the plan, which had all been issued as of September 30, 2013.

The following tables present our assets and liabilities that are measured at fair value on a recurring basis and are categorized using the fair value hierarchy. The fair value hierarchy has three levels based on the reliability of the inputs used to determine fair value. Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 inputs are quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, and inputs (other than quoted prices) that are observable for the asset or liability, either directly or indirectly. Level 3 inputs are unobservable inputs for the asset or liability. A financial asset or liability’s classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement.

The following summarizes the carrying amounts and fair values of financial instruments as of September 30 (in thousands):

Interest rate swaps were measured at fair value using quoted market prices for the swap interest rate indexes over the term of the swap discounted to present value versus the fixed rate of the contract. The estimated fair value of the Company’s term loans was based on information provided by the agent under the Company’s senior secured credit facility. The estimated fair values of the Company’s 2018 Notes, 2020 Notes, 2021 Notes, 2022 Notes and ~~2021~~2024 Notes were based upon quoted market prices.

The Company is exposed to, among other things, the impact of changes in interest rates in the normal course of business. The Company’s risk management program is designed to manage the exposure and volatility arising from these risks, and utilizes derivative financial instruments to offset a portion of these risks. The Company uses derivative financial instruments only to the extent necessary to hedge identified business risks and does not enter into such transactions for trading purposes. The Company generally does not require collateral or other security with counterparties to these financial instruments and is therefore subject to credit risk in the event of nonperformance; however, the Company monitors credit risk and currently does not anticipate nonperformance by other parties. The Company has agreements with each of its Swap counterparties that contain a provision whereby if the Company defaults on the 2014 Credit Facility the Company could also be declared in default on its Swaps, resulting in an acceleration of payment under the Swaps.

Interest rate swap agreements are used to manage interest rate risk associated with floating-rate borrowings under our ~~2013~~2014 Credit Facility. The interest rate swap agreements utilized by the Company effectively modify the Company’s exposure to interest rate risk by converting a portion of the Company’s floating-rate debt to a fixed rate basis through the expiration date of the interest rate swap agreements, thereby reducing the impact of interest rate changes on future interest expense. These agreements involve the receipt of floating rate amounts in exchange for fixed rate interest payments over the term of the agreements without an exchange of the underlying principal amount. These derivative instruments that qualify as effective cash flow hedges under GAAP. For these cash flow hedges, the effective portion of the gain or loss from the financial instruments was initially reported as a component of accumulated other comprehensive income (loss) in stockholders’ equity and subsequently reclassified into earnings in the same line as the hedged item in the same period or periods during which the hedged item affected earnings.

At September 30, ~~2013,~~2014, three forward-starting interest rate swap agreements were in place to swap variable rates on the ~~2013~~2014 Credit Facility for a fixed rate based on an aggregate notional amount of $353 million. These interest rate swap agreements converted the variable interest rate on the aggregate notional amount of the 2013 Credit Facility to a fixed rate of 5.17% (2.17% plus the 3% margin percentage) through June 30, 2015.

In conjunction with the refinancing of the 2011 Credit Facility, the Company no longer designated the interest rate swap agreements relating to the $353 million aggregate notional amount as cash flow hedges for accounting purposes. Accordingly, amounts previously recorded as a component of accumulated other comprehensive loss in stockholder’s equity will be amortized into earnings over the remaining period of the swap agreements.

The net after-tax loss included in accumulated other comprehensive loss to be reclassified into interest expense over the remaining term of the swap ~~agreement~~agreements was ~~$4.8~~$20.1 million at September 30, ~~2013.~~2014.

Accumulated other comprehensive income (loss) consists of the following at September 30 (in thousands):
