PART I

ITEM 1. BUSINESS

The Company

TransDigm Inc. was formed in 1993 in connection with a leveraged buyout transaction. TD Group was formed in 2003 to facilitate a leveraged buyout of TransDigm Inc. The Company was owned by private equity funds until its initial public offering in 2006. TD Group’s common stock is publicly traded on the New York Stock Exchange, or NYSE, under the ticker symbol “TDG.”

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 25 to 30 years. A typical platform can be produced for 20 to 30 years, giving us an estimated product life cycle in excess of 50 years. We estimate that approximately 54% of our net sales in fiscal year 2015 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.

Products

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

Table of Contents

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, seat belts and safety restraints, engineered interior surfaces and related components, lighting and control technology, military personnel parachutes and cargo loading, handling and delivery systems.

Segments

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, specialized AC/DC electric motors and generators and cargo loading and handling systems. 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, seat belts and safety restraints, engineered interior surfaces and related components, lighting and control technology, military personnel parachutes and cargo 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 seat belts 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.

Sales and Marketing

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 business unit manager to certain products. Each business unit 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 business unit 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 S.A.S.).

Manufacturing and Engineering

We maintain 52 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 in our Consolidated Statements of Income. Total engineering expense represents approximately 6% of our operating units’ aggregate costs, or approximately 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 (“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.

Customers

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, 2015, The Boeing Company (which includes Aviall, Inc., a distributor of commercial aftermarket parts to airlines throughout the world) accounted for approximately 12% of our net sales and Airbus S.A.S. accounted for approximately 11% of our net sales. Our top ten customers for fiscal year 2015 accounted for approximately 46% 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 A320 NEO, the 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.

Competition

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.

Government Contracts

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.

Governmental Regulation

The commercial aircraft component industry is highly regulated by 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, our businesses are subject to many other laws and requirements typically applicable to manufacturers and exporters. Without limiting the foregoing, sales of many of our products that will be used on aircraft owned by foreign entities are subject to compliance with export control laws and the manufacture of our products and the operations of our businesses, including the disposal of hazardous wastes, are subject to compliance with applicable environmental laws.

Raw Materials

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. Most of our raw materials and component parts are generally available from multiple suppliers at competitive prices.

Intellectual Property

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.

Backlog

As of September 30, 2015, the Company estimated its sales order backlog at $1,428 million compared to an estimated sales order backlog of $1,195 million as of September 30, 2014. The increase in estimated sales order backlog of approximately $233 million is primarily due to acquisitions. The majority of the purchase orders outstanding as of September 30, 2015 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, 2015 may not necessarily represent the actual amount of shipments or sales for any future period.

Foreign Operations

Although we manufacture a significant portion of our products in the United States, we manufacture some products in Belgium, China, Germany, Hungary, Malaysia, Mexico, Norway, Sri Lanka, Sweden, and the United Kingdom. Although the majority of sales of our products are made to customers (including distributors) located in the United States, our products are ultimately sold to and used by customers (including airlines and other end users of 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 $881.1 million, $735.9 million and $572.0 million for fiscal years 2015, 2014 and 2013, respectively. Sales to foreign customers are subject to numerous additional risks, including foreign currency fluctuations, 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

Table of Contents

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.

Environmental Matters

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 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.

Employees

Legal Proceedings

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.

Available Information

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.

ITEM 1A. RISK FACTORS

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.

Table of Contents

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, 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 accounted for approximately 24% of our net sales in fiscal year 2015) 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.

We rely heavily on certain customers for much of our sales.

Our two largest customers for fiscal year 2015 were The Boeing Company (which includes Aviall, Inc., a distributor of commercial aftermarket parts to airlines throughout the world) and Airbus S.A.S. The Boeing Company accounted for approximately 12% of our net sales and Airbus S.A.S. accounted for approximately 11% of our net sales in fiscal year 2015. Our top ten customers for fiscal year 2015 accounted for approximately 46% 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.

U.S. military spending is dependent upon the U.S. defense budget.

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.


•	suspend us from receiving new contracts pending resolution of alleged violations of procurement laws or regulations;


•	terminate existing contracts;


•	reduce the value of existing contracts; and


•	audit our contract-related costs and fees, including allocated indirect costs.

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.

Furthermore, 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.” Our subsidiaries are periodically subject to a pricing review. 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.

Moreover, U.S. Government purchasing regulations contain a number of additional operation requirements, which do not apply to entities not engaged in government contracting. Failure to comply with such government contracting requirements could result in civil and criminal penalties that could have a material adverse effect on the Company's results of operations.

Table of Contents

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, 2015, our total indebtedness was approximately $8,427.3 million, which was approximately 114.1% of our total book capitalization because of our prior year dividends being funded with indebtedness and the addition of approximately $954 million in total debt in fiscal 2015.

In addition, we may be able to incur substantial additional indebtedness in the future. For example, as of September 30, 2015, we had approximately $534 million of unused commitments under our revolving loan facility and $50 million of unused capacity under our trade receivable securitization facility (the “Securitization Facility”) (with the availability of the capacity under the Securitization Facility being dependent on the amount of our trade receivables outstanding). Although our senior secured credit facility and the indentures (the “Indentures”) governing the 5.50% Senior Subordinated Notes issued in October 2012 (the “2020 Notes”), the 7.50% Senior Subordinated Notes issued in July 2013 (the “2021 Notes”), the 6.00% Senior Subordinated Notes issued in June 2014 (the “2022 Notes), the 6.50% Senior Subordinated Notes issued June 2014 (the “2024 Notes”) and the 6.50% Senior Subordinated Notes issued May 2015 ((the “2025 Notes”) and together with the 2020 Notes, the 2021 Notes, the 2022 Notes, the 2024 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 debt could also have other important consequences to investors. For example, it could:


•	increase our vulnerability to general economic downturns and adverse competitive and industry conditions;


•	increase the risk we are subjected to downgrade or put on a negative watch by the ratings agencies;


•	require us to dedicate a substantial portion of our cash flow from operations to payments on our indebtedness, thereby reducing the availability of our cash flow to fund working capital, capital expenditures, research and development efforts and other general corporate purposes;


•	limit our flexibility in planning for, or reacting to, changes in our business and the industry in which we operate;


•	place us at a competitive disadvantage compared to competitors that have less debt; and


•	limit, along with the financial and other restrictive covenants contained in the documents governing our indebtedness, among other things, our ability to borrow additional funds, make investments and incur liens.

In addition, all of our debt under the senior secured credit facility, which includes $4,377 million in term loans and a revolving loan facility of $550 million, bears interest at floating rates. Accordingly, if interest rates increase, our debt service expense will also increase. In order to reduce the floating interest rate risk, as of September 30, 2015, six interest rate cap agreements beginning on September 30, 2015 were in place to offset the variable interest rates based on an aggregate notional amount of $750 million of debt under the senior secured credit facility. Also, three forward starting interest rate swap agreements were in place that fix the interest on an aggregate notional amount of $1,000 million of debt under the senior secured credit facility. In addition, 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 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.

Table of Contents

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 Notes, amounts borrowed under the senior secured credit facility, 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 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 Securitization Facility, 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 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:


•	incur or guarantee additional indebtedness or issue preferred stock;


•	pay distributions on, redeem or repurchase our capital stock or redeem or repurchase our subordinated debt;


•	make investments;


•	sell assets;


•	enter into agreements that restrict distributions or other payments from our restricted subsidiaries to us;


•	incur or allow to exist liens;


•	consolidate, merge or transfer all or substantially all of our assets;


•	engage in transactions with affiliates;


•	create unrestricted subsidiaries; and


•	engage in certain business activities.

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 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 Notes. If the debt under the senior secured credit facility or the 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.

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.

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, 2015, we had approximately 8,200 full-time, part-time and temporary employees. Approximately 8% 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 April 2016 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.

Table of Contents

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. Disruptions could also occur due to cyber-attacks, computer or equipment malfunction (accidental or intentional), operator error or process failures. Any disruption of our ability to operate our business could result in a material decrease in our revenues or significant additional costs to replace, repair or insure our assets, which could have a material adverse impact on our financial condition and results of operations.

Operations and sales outside of the United States may be subject to additional risks.

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. Furthermore, the Company is subject to laws and regulations, such as the Foreign Corrupt Practices Act or similar local anti-bribery laws, which generally prohibit companies and their employees, agents and contractors from making improper payments to governmental officials for the purpose of obtaining or retaining business. Failure to comply with these laws could subject the Company to civil and criminal penalties that could materially adversely affect the Company’s results of operations.

We face significant competition.

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 product 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 could incur substantial costs as a result of data protection concerns.

The interpretation and application of data protection laws in the U.S., Europe and elsewhere are uncertain and evolving. It is possible that these laws may be interpreted and applied in a manner that is inconsistent with our data practices. Compliance could cause us to incur substantial costs or require us to change our business practices in a manner adverse to our business.

In addition, despite our efforts to protect confidential information, our facilities and systems may be vulnerable to data loss, including cyber-attacks. This could lead to negative publicity, legal claims, theft, modification or destruction of proprietary or key information, damage to or inaccessibility of critical systems, manufacture of defective products, production downtimes, operational disruptions and other significant costs, which could adversely affect our reputation, financial condition and results of operations.

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 $1,539.9 million at September 30, 2015, representing approximately 18.3% of our total assets. Goodwill recognized in accounting for the mergers and acquisitions was approximately $4,686.2 million at September 30, 2015, representing approximately 55.6% 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

Table of Contents

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. 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 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.

We do not pay regular quarterly or annual cash dividends on our stock.

On October 15, 2012, July 3, 2013 and June 4, 2014 the Company’s board of directors authorized and declared special cash 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.

Notwithstanding the special cash dividends paid in October 2012, 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.

Holders

On November 3, 2015, there were 44 stockholders of record of our common stock. We estimate that there were approximately 50,215 beneficial stockholders as of November 3, 2015, which includes an estimated amount of stockholders who have their shares held in their accounts by banks and brokers.

Dividends

In June 2014, TD Group’s Board of Directors declared a special cash dividend of $25.00 on each outstanding share of common stock. No dividends were declared in fiscal 2015.

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.

2003 Stock Option Plan

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. As of September 30, 2015, there were options to purchase 118,502 shares of TD Group common stock outstanding. There are no shares available for issuance under options not yet granted as the stock option plan has expired and no further grants will be made from the plan.

2006 Stock Incentive Plan

Prior to the consummation of its initial public offering, TD Group adopted a new stock incentive plan, which was amended most recently on 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. The total number of shares of TD Group common stock reserved for issuance or delivery under the 2006 stock incentive plan is 8,119,668, 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, 2015, there were 25,962 shares of common stock issued and outstanding under the 2006 stock incentive plan that had been issued to directors. As of September 30, 2015, there were 17,700 restricted stock units issued and outstanding under the 2006 stock incentive plan. In addition, options to purchase 7,388,062 shares had been issued thereunder, of which 5,265,543 were outstanding. As of September 30, 2015, there were 687,944 shares available for issuance under awards not yet granted. The stock incentive plan will expire on March 14, 2016 and no further shares will be granted under the plan thereafter.

2014 Stock Option Plan

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, 2015, there were no options to purchase shares issued thereunder.

Non-GAAP Financial Measures

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.

Table of Contents

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:


•	neither EBITDA nor EBITDA As Defined reflects the significant interest expense, or the cash requirements necessary to service interest payments, on our indebtedness;


•	although depreciation and amortization are non-cash charges, the assets being depreciated and amortized will often have to be replaced in the future, and neither EBITDA nor EBITDA As Defined reflects any cash requirements for such replacements;


•	the omission of the substantial amortization expense associated with our intangible assets further limits the usefulness of EBITDA and EBITDA As Defined;


•	neither EBITDA nor EBITDA As Defined includes the payment of taxes, which is a necessary element of our operations; and


•	EBITDA As Defined excludes the cash expense we have incurred to integrate acquired businesses into our operations, which is a necessary element of certain of our acquisitions.

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.

These risks could cause our actual results to differ materially from any future performance suggested below.

Overview

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, seat belts and safety restraints, engineered interior surfaces and related components, lighting and control technology, military personnel parachutes and cargo loading, handling and 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.

Long-term Sustainable Growth

For fiscal year 2015, we generated net sales of $2,707.1 million, gross profit of $1,449.8 million or 53.6% of sales, and net income of $447.2 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.

We believe our key competitive strengths include:

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 95,000 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.

Value-Driven Operating Strategy. Our three core value drivers are:


•	Obtaining Profitable New Business. We attempt to obtain profitable new business by using our technical expertise and application skill and our detailed knowledge of our customer base and the individual niche markets in which we operate. We have regularly been successful in identifying and developing both aftermarket and OEM products to drive our growth.

Table of Contents


•	Improving Our Cost Structure. We are committed to maintaining and continuously improving our lean cost structure through detailed attention to the cost of each of the products that we offer and our organizational structure, with a focus on reducing the cost of each.

•

Providing Highly Engineered Value-Added Products to Customers. We focus on the engineering, manufacturing and marketing of a broad range of highly engineered niche products that we believe provide value to our customers. We believe we have been consistently successful in communicating to our customers the value of our products. This has generally enabled us to price our products to fairly reflect the value we provide and the resources required to do so.

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 55 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.

Acquisitions and divestitures during the previous three fiscal years are more fully described in Note 2, “Acquisitions” in the Notes to Consolidated Financial Statements included herein.

Trend Information

We predominantly serve customers in the commercial, regional, business jet and general aviation aftermarket, which accounts for approximately 37% of total sales; the commercial aerospace OEM market, comprising large commercial transport manufacturers and regional and business jet manufacturers, which accounts for approximately 29% of total sales; and the defense market, which accounts for approximately 29% of total sales. Non-aerospace sales comprise approximately 5% of our total sales.

Table of Contents

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 2015 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 2016 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.

Commercial Aftermarket

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 2015 and current industry consensus indicates that positive RPM growth will continue in 2016.

Commercial OEM Market

The commercial transport market sector, the largest sector in the commercial OEM market, continued to grow during 2015. 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 2016 shipments will be a function of, among other things, the estimated 2016 and 2017 commercial airframe production rates. We 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 2016 and 2017, though the growth may moderate and begin to flatten.

Defense

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. 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 to be flat in future years over the recent high levels.

Critical Accounting Policies

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.

Table of Contents

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, see Note 3, “Summary of Significant Accounting Policies” in the Notes to 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. Collectibility 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.

Inventories: Inventories are stated at the lower of cost or market. Cost of inventories is generally determined by the average cost and the first-in, first-out (FIFO) methods and includes material, labor and overhead related to the manufacturing process. Because the Company sells products that are installed on airframes that can be in-service for 25 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.

Table of Contents

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 unit’s estimated fair value is reconciled to the total market capitalization of the Company.

The Company had 29 reporting units with goodwill as of the first day of the fourth quarter of fiscal 2015, 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, 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.

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.

	$	2,707.1	$	2,372.9	$	334.2	14.1	%

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 attributable to the acquisitions of Telair Cargo Group, Adams Rite Aerospace GmbH, Pexco Aerospace and PneuDraulics in fiscal 2015 and Airborne and EME in fiscal 2014.

Commercial aftermarket sales increased $36.9 million, or an increase of 4.2%, defense sales increased $29.8 million, or an increase of 4.3%, and commercial OEM sales increased $16.4 million, or an increase of 2.4%, for the fiscal year ended September 30, 2015 compared to the fiscal year ended September 30, 2014.

Cost of Sales and Gross Profit. Cost of sales increased by $152.3 million, or 13.8%, to $1,257.3 million for the fiscal year ended September 30, 2015 compared to $1,105.0 million for the fiscal year ended September 30, 2014. Cost of sales and the related percentage of total sales for the fiscal years ended September 30, 2015 and 2014 were as follows (amounts in millions):

Gross profit	$	1,449.8		$	1,267.9		$	181.9		14.3	%
Gross profit percentage	53.6		%	53.4		%	0.2		%

The increase in the dollar amount of cost of sales during the fiscal year ended September 30, 2015 was primarily due to increased volume associated with the sales from acquisitions and organic sales growth.

Gross profit as a percentage of sales increased by 0.2 percentage points to 53.6% for the fiscal year ended September 30, 2015 from 53.4% for the fiscal year ended September 30, 2014. The dollar amount of gross profit increased by $181.9 million, or 14.3%, for the fiscal year ended September 30, 2015 compared to the comparable period last year due to the following items:

•

Gross profit on the sales from the acquisitions indicated above (excluding acquisition-related costs) was approximately $100 million for the fiscal year ended September 30, 2015, which represented gross profit of approximately 39% of the acquisition sales. The lower gross profit margin on the acquisition sales reduced gross profit as a percentage of consolidated sales by approximately 2 percentage points.

•

Organic sales growth described above, application of our three core value-driven operating strategies (obtaining profitable new business, continually improving our cost structure, and providing highly engineered value-added products to customers), and positive leverage on our fixed overhead costs spread over a higher production volume, resulted in a net increase in gross profit of approximately $83 million for the fiscal year ended September 30, 2015.


•	Slightly offsetting the increases in gross profit was the impact of higher inventory purchase accounting adjustments charged to cost of sales of approximately $1 million.

Selling and Administrative Expenses. Selling and administrative expenses increased by $45.2 million to $321.6 million, or 11.9% of sales, for the fiscal year ended September 30, 2015 from $276.4 million, or 11.6% 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, 2015 and 2014 were as follows (amounts in millions):

Table of Contents



	Fiscal Years Ended						Change		% Change

Total selling and administrative expenses	$	321.6		$	276.4		$	45.2	16.4	%
% of total sales	11.9		%	11.6		%

The increase in the dollar amount of selling and administrative expenses during the fiscal year ended September 30, 2015 is primarily due to higher selling and administrative expenses relating to recent acquisitions of approximately $23 million, which was approximately 9% of the acquisition sales, and higher acquisition-related and stock compensation expenses of $12.4 million and $4.4 million, respectively.

Amortization of Intangible Assets. Amortization of intangible assets decreased to $54.2 million for the fiscal year ended September 30, 2015 from $63.8 million for the comparable period last year. The net decrease of $9.6 million was primarily due to order backlog amortization expense from prior acquisitions becoming fully amortized.

Refinancing Costs. Refinancing costs of $18.4 million were recorded during the year ended September 30, 2015 representing debt issue costs expensed in connection with the debt financing activity in May 2015. Included within the $18.4 million was approximately $10.2 million of unamortized debt issue costs written off. Refinancing costs of $131.6 million were recorded during the fiscal year ended September 30, 2014 representing debt issue costs expensed in conjunction with the repurchase of the 2018 Notes. The $131.6 million expense 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.

Interest Expense-net. Interest expense-net includes interest on borrowings outstanding, amortization of debt issue costs and revolving credit facility fees offset by interest income. Interest expense-net increased $71.1 million, or 20.4%, to $418.8 million for the fiscal year ended September 30, 2015 from $347.7 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 $7,827 million for the fiscal year ended September 30, 2015 and approximately $6,310 million for the fiscal year ended September 30, 2014 slightly offset by a decrease in the weighted average cash interest rate during the fiscal year ended September 30, 2015 of 5.2% compared to the weighted average cash interest rate during the comparable prior period of 5.3%. The increase in weighted average level of borrowings was primarily due to the issuance of the 2025 Notes for $450.0 million in May 2015 and the additional incremental term loan of $1,000.0 million in May 2015. The weighted average interest rate for cash interest payments on total borrowings outstanding at September 30, 2015 was 5.0%.

Income Taxes. Income tax expense as a percentage of income before income taxes was approximately 29.8% for the fiscal year ended September 30, 2015 compared to 31.6% for the fiscal year ended September 30, 2014. The Company’s effective tax rate for these periods was less than the Federal statutory tax rate due primarily to the domestic manufacturing deduction, foreign earnings taxed at rates lower than the U.S. statutory rates, and a discrete adjustment from filing fiscal 2014 and 2013 U.S. income tax returns. The decrease in the effective tax rate for the fiscal year ended September 30, 2015 compared to the fiscal year ended September 30, 2014 was primarily due to the ability to recognize the benefit from the utilization of foreign tax credits in the current and future years, foreign earnings taxed at rates lower than the U.S. statutory rate, and a discrete adjustment related to the closing of the fiscal year 2012 and 2013 IRS examination.

Net Income. Net income increased $140.3 million, or 45.7%, to $447.2 million for the fiscal year ended September 30, 2015 compared to net income of $306.9 million for the year ended September 30, 2014, primarily as a result of the factors referred to above.

Earnings per Share. The basic and diluted earnings per share were $7.84 for the fiscal year ended September 30, 2015 and $3.16 per share for the fiscal year ended September 30, 2014. Net income for the fiscal year ended September 30, 2015 of $447.2 million was decreased by dividend equivalent payments of $3.4 million resulting in net income available to common shareholders of $443.8 million. 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. The increase in earnings per share of $4.68 per share to $7.84 per share is a result of the factors referred to above.

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 acquisitions 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, 2014 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 fiscal year ended September 30, 2013.

Gross profit	$	1,267.9		$	1,049.6		$	218.3		20.8	%
Gross profit percentage	53.4		%	54.5		%

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:

•

Gross profit on the sales from the acquisitions indicated above (excluding acquisition-related costs) was approximately $108 million for the fiscal year ended September 30, 2014, which represented gross profit of approximately 37% of the acquisition sales. The lower gross profit margin on the acquisition sales reduced gross profit as a percentage of consolidated sales by approximately 2 percentage points.


•	Impact of lower inventory purchase accounting adjustments and acquisition integration costs charged to cost of sales of approximately $2 million.


•	Impact of lower stock compensation expense of approximately $3 million mainly due to accelerated vesting in fiscal 2013 (discussed further below).

Organic sales growth described above, application of our three core value-driven operating strategies (obtaining profitable new business, continually improving our cost structure, and providing highly engineered value-added products to customers), and positive leverage on our fixed overhead costs spread over a higher production volume, resulted in a net increase in gross profit of approximately $105 million for the fiscal year ended September 30, 2014.

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):



	Fiscal Years Ended						Change			% Change
	September 30, 2014			September 30, 2013			Change			% Change
Selling and administrative expenses—excluding costs below	$	249.4		$	204.8		$	44.6		21.8	%
% of total sales	10.4		%	10.6		%

Total selling and administrative expenses	$	276.4		$	254.5		$	21.9		8.6	%
% of total sales	11.6		%	13.2		%

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 $1 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 $63.8 million for the fiscal year ended September 30, 2014 from $45.6 million for the comparable period last year. The net increase of $18.2 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 fiscal year ended September 30, 2014 representing debt issue costs expensed in conjunction with the repurchase of the 2018 Notes.

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 Term Loans and 2011 Term Loans in February 2013.

Interest Expense-net. Interest expense-net includes interest on borrowings outstanding, 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 $6,310 million for the fiscal year ended September 30, 2014 and approximately $4,630 million 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 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 Term Loans. The weighted average interest rate for cash interest payments on total borrowings outstanding 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 was 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 borrowings outstanding 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.
