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.”
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. We estimate that about 90% of our net sales for fiscal year 2017 were generated by proprietary products. In addition, for fiscal year 2017, we estimate that we generated about 80% of our net sales from products for which we are the sole source provider.
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 55% of our net sales in fiscal year 2017 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 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.

Table of Contents

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, databus and power controls, 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, high performance hoists, winches and lifting devices 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, databus and power controls, high performance hoists, winches and lifting devices 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 OEM 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 OEM 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 included herein.
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 business unit 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 serve as a 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 approximately 60 principal manufacturing facilities. Most of our manufacturing facilities are comprised of manufacturing, distribution and engineering functions, and most facilities have certain administrative functions, including

2

Table of Contents

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 accounting and reporting, 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 and research and development costs are recorded in selling and administrative expenses in our consolidated statements of income. The aggregate of engineering expense and research and development expense represents approximately 8% 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 as required by our customers, such as 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. Refer to Note 3, “Summary of Significant Accounting Policies,” to the consolidated financial statements included herein with respect to total costs of research and development, which is incorporated herein by reference.
Customers
We predominantly serve customers in the commercial, regional, business jet and general aviation aftermarket, which accounts for approximately 35% of total sales; the commercial aerospace OEM market, comprising large commercial transport manufacturers and regional and business jet manufacturers, which accounts for approximately 26% of total sales; and the defense market, which accounts for approximately 34% of total sales. Non-aerospace sales comprise approximately 5% of our total sales.
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, 2017, Airbus S.A.S. (which includes Satair A/S, a distributor of commercial aftermarket parts to airlines throughout the world) accounted for approximately 13% of our net sales and The Boeing Company (which includes Aviall, Inc., also a distributor of commercial aftermarket parts to airlines throughout the world) accounted for approximately 11% of our net sales. Our top ten customers for fiscal year 2017 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 (including the 737MAX), 747, 767 and 787, the Airbus A320 family (including neo), A330, A350 and A380, the Bombardier CSeries, CRJ’s, Q400/Dash-8 aircraft, Challenger and Learjets, the Embraer Regional and business jets, the Cessna Citation family, the Gulfstream aircraft family, the Dassault aircraft family, the HondaJet and the ATR42/72 turboprop. Military platforms include aircraft such as the Boeing AH-64 Apache, CH-47, C17 Chinook, F-15, F-18, KC46 Tanker, P-8 and V-22, the Airbus A400M, the Lockheed Martin C-130J, F-16 and F-35 Joint Strike Fighter, UH-60 Blackhawk helicopter, the Northrop Grumman E-2C Hawkeye, the General Atomics Predator Drone and the Raytheon Patriot Missile. We have been awarded numerous contracts for the development of engineered products for production on the Airbus A330neo, the Boeing 777x, the Bombardier Global 7000/8000, the Embraer E2, the Mitsubishi Regional Jet and the Sikorsky S-97 and JMR helicopter.
The markets in which we sell our products are, to varying degrees, cyclical and have experienced upswings and downturns. The demand for our commercial 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, the percentage of the worldwide fleet that is in warranty, and airline profitability. The demand for defense products is specifically dependent on government budget trends, military campaigns and political pressures.
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

3

Table of Contents

in the development and certification of products may create disincentives for potential new competitors for certain products. If 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 and impose criminal penalties based on 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; (5) control and potentially prohibit the export of our products; and (6) seek repayment of contract related payments under certain circumstances.
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.
Market Channels
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 through 2017 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 2018 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, political pressures 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

4

Table of Contents

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 and the percentage of the fleet that is in warranty.
Commercial OEM Market
The commercial transport market sector, the largest sector in the commercial OEM market, grew modestly during 2017. 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 2018 shipments will be a function of, among other things, the estimated 2018 and 2019 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 2018 and 2019, though the growth may continue to 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. 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.
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, 2017, the Company estimated its sales order backlog at $1,669 million compared to an estimated sales order backlog of $1,554 million as of September 30, 2016. The increase in estimated sales order backlog is primarily due to acquisitions. The majority of the purchase orders outstanding as of September 30, 2017 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, 2017 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.
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

5

Table of Contents

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.
Employees
As of September 30, 2017, we had approximately 9,200 full-time, part-time and temporary employees. Approximately 11% of our full-time and part-time employees were represented by labor unions. Collective bargaining agreements between us and these labor unions expire at various dates ranging from February 2018 to November 2020. We consider our relationship with our employees generally to be satisfactory.
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.
Our commercial 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 commercial business is directly affected by, among other factors, changes in revenue passenger miles (RPMs), the size and age of the worldwide aircraft fleet, the percentage of the fleet that is out-of-warranty and 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 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 (SARS) epidemic, and the conflicts abroad, and could be impacted by future geopolitical or other worldwide events, such as war, terrorist acts, or a worldwide infectious disease outbreak. In addition, global market and economic conditions have been challenging with 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, and delay refurbishments and discretionary spending. If demand for spare parts decreases, there would be a decrease in demand for certain of our products. An adverse change in demand could impact our results of operations, collection of accounts receivable and our expected cash flow generation from current and acquired businesses which may adversely impact our financial condition and access to capital markets.
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 collectively accounted for approximately 25% of our net sales in fiscal year 2017) 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, interest rates, downturns in the global economy and national and international events. 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 2017 were Airbus S.A.S. (which includes Satair A/S) and The Boeing Company (which includes Aviall, Inc.). Airbus S.A.S. accounted for approximately13% of our net sales and The Boeing Company accounted for approximately 11% of our net sales in fiscal year 2017. Our top ten customers for fiscal year 2017 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.

Table of Contents

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 internationally 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 or may be unable to receive necessary regulatory approvals or support. 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.
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:
suspend us from receiving new contracts based on 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.

Table of Contents

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 and in fact, government buying agencies that purchase some of our subsidiaries’ products are currently the subject of a DOD Office of Inspector General audit with respect to prices paid for such products. Pricing reviews and government audits, including the one underway, 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.
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 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, 2017, our total indebtedness, excluding approximately $16 million of letters of credit outstanding, was approximately $11.8 billion, which was 133.5% of our total book capitalization as a result of our dividends being funded, in part, with indebtedness and the addition of approximately $1.6 billion in net new incremental borrowings during fiscal 2017.
In addition, we may be able to incur substantial additional indebtedness in the future. For example, as of September 30, 2017, we had approximately $584 million of unused commitments under our revolving loan facility. Although our senior secured credit facility and the indentures governing the various senior subordinated notes outstanding (the “Indentures”) 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. For example, if the usage of the revolving loan facility exceeds 25% of the total revolving commitments, the Company will be required to maintain a maximum consolidated net leverage ratio of net debt, as defined, to trailing four-quarter EBITDA As Defined. A breach of any of the covenants or an inability to comply with the required leverage ratio could result in a default under the senior secured credit facility or the Indentures.
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 requirements, capital expenditures, acquisitions, research and development efforts and other general corporate requirements;

8

Table of Contents

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 $7.0 billion in term loans and a revolving loan facility of $600 million, bears interest at floating rates. Accordingly, if interest rates increase, our debt service expense will also increase. Interest rate swap and cap agreements are used to manage interest rate risk associated with floating-rate borrowings under our credit facilities. For information about our interest rate swap and cap agreements, see Note 20, “Derivatives and Hedging Instruments,” in the notes to the consolidated financial statements included herein.
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 Indentures. We cannot assure that our business will generate sufficient cash flow from operations or that future borrowings will be available to us under the senior secured credit facility or otherwise in amounts sufficient to enable us to service our indebtedness. If we cannot service our debt, we will have to take actions such as reducing or delaying capital investments, selling assets, restructuring or refinancing our debt or seeking additional equity capital.
To service our indebtedness, we will require a significant amount of cash. Our ability to generate cash depends on many factors beyond our control and any failure to meet our debt service obligations could harm our business, financial condition and results of operations.
Our ability to make payments on and to refinance our indebtedness, including the Indentures, 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 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 Indentures, 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 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 Indentures.
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;

9

Table of Contents

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 senior subordinated 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 senior subordinated notes. If the debt under the senior secured credit facility or the senior subordinated notes were to be accelerated, we cannot assure 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.
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.
We are dependent on our senior management team and 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.
Although we believe that our relations with our employees are satisfactory, we cannot assure that we will be able to negotiate a satisfactory renewal of 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.
In addition, our success depends in part on our ability to attract and motivate our senior management and key employees. Achieving this objective may be difficult due to a variety of factors, including fluctuations in economic and industry conditions, competitors’ hiring practices, and the effectiveness of our compensation programs. Competition for qualified personnel can be intense. A loss of senior management and key personnel, or failure to attract qualified new talent could prevent us from capitalizing on business opportunities, and our operating results and/or market value could be adversely affected. The Board continually monitors this risk and we believe that the Board’s succession plan, together with our straightforward strategy, clear value drivers, decentralized nature and the quality of managers running our operating units helps to mitigate this risk.
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

10

Table of Contents

of our suppliers to provide materials of the requisite quality), or by increased costs of such raw materials or components if we were unable to pass along such price increases to our customers. Because we maintain a relatively small inventory of raw materials and component parts, our business could be adversely affected if we were unable to obtain these raw materials and components from our suppliers in the quantities we require or on favorable terms. Although we believe in most cases that we could identify alternative suppliers, or alternative raw materials or component parts, the lengthy and expensive FAA and OEM certification processes associated with aerospace products could prevent efficient replacement of a supplier, raw material or component part.
Our operations depend on our manufacturing facilities, which are subject to physical and other risks that could disrupt production.
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, UK Bribery Act and similar local anti-bribery laws, which generally prohibit companies and their employees, agents and contractors from making improper payments 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.

Table of Contents

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 $1.7 billion at September 30, 2017, representing approximately 17% of our total assets. Goodwill recognized in accounting for the mergers and acquisitions was approximately $5.7 billion at September 30, 2017, representing approximately 58% of our total assets. We may never realize the full value of our identifiable intangible assets and goodwill, and to the extent we were to determine that our identifiable intangible assets or our goodwill were impaired within the meaning of applicable accounting standards, we would be required to write-off the amount of any impairment.
The Company may be subject to risks relating to changes in its tax rates or exposure to additional income tax liabilities.
The Company is subject to income taxes in the United States and various non-U.S. jurisdictions. The Company’s domestic and international tax liabilities are dependent upon the location of earnings among these different jurisdictions. The Company’s future results of operations could be adversely affected by changes in the Company’s effective tax rate as a result of changes in the mix of earnings in countries with differing statutory tax rates, changes in the valuation of deferred tax assets, challenges by tax authorities or changes in tax laws or regulations. In addition, the amount of income taxes paid by the Company is subject to ongoing audits by U.S. federal, state and local tax authorities and by non-U.S. tax authorities. If these audits result in assessments different from amounts reserved, future financial results may include unfavorable adjustments to the Company’s tax liabilities, which could have a material adverse effect on the Company’s results of operations.
Our stock price may be volatile, and an 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 operating performance of the companies issuing the securities. These market fluctuations may negatively affect the market price of our common stock. Shareholders may not be able to sell their shares at or above the purchase price due to fluctuations in the market price of our common stock. Such changes could be 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 such changes could be unrelated to our operating performance, such as changes in market conditions affecting the stock market generally or the stocks of aerospace companies or changes in the outlook for our common stock, such as changes to or the confidence in our business strategy, changes to or confidence in our management, or expectations for future growth of the Company.
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 regularly declare and pay quarterly or annual cash dividends on our stock.
On July 3, 2013, June 4, 2014, October 14, 2016 and August 23, 2017, the Company’s Board of Directors authorized and declared special cash dividends of $22.00, $25.00, $24.00 and $22.00, 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, we do not anticipate declaring 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, shareholders should not rely on regular quarterly or annual dividend income from shares of our common stock and should not rely on special dividends with any regularity or at all.

Holders
On November 3, 2017, there were 30 stockholders of record of our common stock. We estimate that there were approximately 62,000 beneficial stockholders as of November 3, 2017, which includes an estimated amount of stockholders who have their shares held in their accounts by banks and brokers.
Dividends
On October 14, 2016, TD Group’s Board of Directors authorized and declared a special cash dividend of $24.00 on each outstanding share of common stock and cash dividend equivalent payments under options granted under its stock option plans. The record date for the special dividend was October 24, 2016, and the payment date for the dividend was November 1, 2016. On August 23, 2017, TD Group’s Board of Directors authorized and declared a special cash dividend of $22.00 on each outstanding share of common stock and cash dividend equivalent payments under options granted under its stock option plans. The record date for the special dividend was September 5, 2017, and the payment date for the dividend was September 12, 2017. No dividends were declared in fiscal 2015 or fiscal 2016.
We do not anticipate declaring regular quarterly or annual cash dividends on our common stock in the near future. Any declaration 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 the senior secured credit facility and Indentures, 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 senior secured credit facility and Indentures and may be limited by future debt or other agreements that we may enter into.

Purchases of Equity Securities by the Issuer or Affiliated Purchaser
On October 22, 2014, our Board of Directors authorized a stock repurchase program permitting us to repurchase a portion of our outstanding shares not to exceed $300 million in the aggregate. No shares were repurchased under the program in fiscal 2015. On January 21, 2016, our Board of Directors authorized a stock repurchase program replacing the $300 million program with a repurchase program permitting us to repurchase a portion of our outstanding shares not to exceed $450 million in the aggregate, subject to any restrictions specified in the Credit Agreement and/or Indentures. During fiscal 2016, under the aforementioned authorized programs, the Company repurchased 1,015,387 shares of its common stock at a gross cost of approximately $207.8 million at the weighted-average price per share of $204.61.
On January 26, 2017, our Board of Directors increased the authorized amount of repurchases allowable under the stock program from $450 million to $472 million. The increase in the allowable repurchases aligned the program with the restricted payments allowable under the Credit Agreement. During January 2017, the Company repurchased 666,755 shares of its common stock at a gross cost of approximately $150 million at the weighted average cost of $224.97 under the $472 million stock repurchase program. On March 7, 2017, our Board of Directors authorized a new stock repurchase program replacing the $472 million program permitting repurchases of outstanding shares not to exceed $600 million in the aggregate, subject to any restrictions specified in the Credit Agreement and/or Indentures governing the existing Notes. During March 2017, the Company repurchased 851,069 shares of its common stock at a gross cost of approximately $189.8 million at the weighted average cost of $223.05 under the new $600 million stock repurchase program. Additionally, during May 2017, the Company repurchased 205,800 shares of its common stock at a gross cost of approximately $50 million at the weighted average cost of $242.90 under the new $600 million stock repurchase program. As of September 30, 2017, the remaining amount of repurchases allowable under the $600 million program was $360.2 million subject to any restrictions specified in the Credit Agreement and/or Indentures governing the existing Notes as described within the Liquidity and Capital Resources section of Item 7. - “Management’s Discussion and Analysis of Financial Conditions and Results of Operations.”
On November 8, 2017, our Board of Directors, authorized a new stock repurchase program replacing the $600 million program permitting repurchases of our outstanding shares not to exceed $650 million in the aggregate, subject to any restrictions specified in the Credit Agreement and/or Indentures governing the existing Notes.
During the fiscal years ended September 30, 2017 and 2016, the Company received 2,548 shares in each period as forfeitures in lieu of payment for withholding taxes on the vesting of restricted stock. The deemed gross cost of the shares was approximately $0.6 million in each period at a weighted-average price per share of $247.33 and $225.58, respectively.

Net earnings per share is calculated by dividing net income applicable to common stock by the basic and diluted weighted average common shares outstanding.
(3)
In connection with adopting ASU 2015-17, “Balance Sheet Classification of Deferred Taxes,” for reporting periods ended after October 1, 2015, the Company reclassified $45,375, $37,669, and $30,182 from current deferred income tax assets in our consolidated balance sheets as of September 2015, 2014, and 2013, respectively, to non-current deferred income tax liabilities.
(4)
In connection with adopting ASU 2015-03, “Simplifying the Presentation of Debt Issuance Costs,” for reporting periods ended after October 1, 2015, the Company reclassified $77,740, $92,393, and $72,668 from debt issuance costs in our consolidated balance sheets as of September 2015, 2014, and 2013, respectively, to the current portion of long-term and long-term-term debt.
(5)
During the fourth quarter of 2017, the Company committed to disposing of Schroth in connection with the settlement of a Department of Justice investigation into the competitive effects of the acquisition. Therefore, Schroth was classified as held-for-sale and as discontinued operations as of September 30, 2017. The Company acquired Schroth in February 2017 (refer to Note 2, “Acquisitions”). The loss from discontinued operations in the consolidated statements of income for the year ended September 30, 2017 includes a $32.0 million impairment charge to write down the assets to fair value. Refer to Note 22, “Discontinued Operations,” for further information.
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 commitments under our senior secured credit facility requires compliance under certain circumstances, on a pro forma basis, with a financial covenant that measures the ratio of the amount of our secured indebtedness to the amount of our Consolidated EBITDA defined in the same manner as we define EBITDA As Defined herein.
In addition to the above, our management uses EBITDA As Defined to review and assess the performance of the management team in connection with employee incentive programs and to prepare its annual budget and financial projections. Moreover, our management uses EBITDA As Defined to evaluate acquisitions.
Although we use EBITDA and EBITDA As Defined as measures to assess the performance of our business and for the other purposes set forth above, the use of these non-GAAP financial measures as analytical tools has limitations, and you should not consider any of them in isolation, or as a substitute for analysis of our results of operations as reported in accordance with GAAP. Some of these limitations are:

21

Table of Contents

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.

For purposes of computing the ratio of earnings to fixed charges, earnings consist of earnings from continuing operations before income taxes plus fixed charges. Fixed charges consist of interest expense, amortization of debt issuance costs, original issue discount and premium and the portion (approximately 33%) of rental expense that management believes is representative of the interest component of rental expense.
(2)
EBITDA represents earnings from continuing operations before interest, taxes, depreciation and amortization. EBITDA As Defined represents EBITDA plus, as applicable for each relevant period, certain adjustments as set forth in the reconciliation of net income to EBITDA and EBITDA As Defined and the reconciliation of net cash provided by operating activities to EBITDA and EBITDA As Defined presented below. See “Non-GAAP Financial Measures” for additional information and limitations regarding these non-GAAP financial measures.

ITEM 7.
MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
The following discussion of our financial condition and results of operations should be read together with “Selected Financial Data” and TD Group’s consolidated financial statements and the related notes included elsewhere in this report. The following discussion may contain predictions, estimates and other forward-looking statements that involve a number of risks and uncertainties, including those discussed under the heading entitled “Risk Factors” included elsewhere in this report. These risks could cause our actual results to differ materially from any future performance suggested below.
Overview
For fiscal year 2017, we generated net sales of $3,504.3 million, gross profit of $1,984.6 million or 56.6% of sales, and net income of $596.9 million. We believe we have achieved steady, long-term growth in sales and improvements in operating performance since our formation in 1993 due to our competitive strengths and through execution of our value-driven operating strategy. More specifically, focusing our businesses on our value-driven operating strategy of obtaining profitable new business, carefully controlling the cost structure and pricing our highly engineered value-added products to fairly reflect the value we provide and the resources required to do so has historically resulted in improvements in gross profit and income from operations over the long term.
Our selective acquisition strategy has also contributed to the growth of our business. The integration of certain acquisitions into our existing businesses combined with implementing our proven operating strategy has historically resulted in improvements of the financial performance of the acquired business.
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.
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 potential disincentives to competition for certain products.
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.
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 approximately 60 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 during the previous three fiscal years are more fully described in Note 2, “Acquisitions,” in the notes to the consolidated financial statements included herein.
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.
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 the 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.
Allowance for Doubtful Accounts: 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.
Goodwill and Other Intangible Assets: In accordance with ASC 805, “Business Combinations,” the Company uses the acquisition method of accounting to allocate costs of acquired businesses to the assets acquired and liabilities assumed based on their estimated fair values at the dates of acquisition. The excess costs of acquired businesses over the fair values of the assets acquired and liabilities assumed were recognized as goodwill. The valuations of the acquired assets and liabilities will impact the determination of future operating results. In addition to using management estimates and negotiated amounts, the Company used a variety of information sources to determine the estimated fair values of acquired assets and liabilities including third-party appraisals for the estimated value and lives of identifiable intangible assets. 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.
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

26

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, the Company first assesses qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount, and whether it is necessary to perform the quantitative goodwill impairment test. The quantitative test is required only if the Company concludes that it is more likely than not that a reporting unit’s fair value is less than its carrying amount, or if the Company elects not to perform a qualitative assessment of a reporting unit. For the quantitative test, management determines the estimated fair value through the use of a discounted cash flow valuation model incorporating discount rates commensurate with the risks involved for each reporting unit. If the calculated estimated fair value is less than the current carrying value, impairment of goodwill of the reporting unit may exist. The use of a discounted cash flow valuation model to determine estimated fair value is common practice in impairment testing. The key assumptions used in the discounted cash flow valuation model for impairment testing includes discount rates, growth rates, cash flow projections and terminal value rates. Discount rates are set by using the Weighted Average Cost of Capital (“WACC”) methodology. The WACC methodology considers market and industry data as well as company specific risk factors for each reporting unit in determining the appropriate discount rates to be used. The discount rate utilized for each reporting unit is indicative of the return an investor would expect to receive for investing in such a business.
Management, considering industry and company-specific historical and projected data, develops growth rates, sales projections and cash flow projections for each reporting unit. Terminal value rate determination follows common methodology of capturing the present value of perpetual cash flow estimates beyond the last projected period assuming a constant WACC and low long-term growth rates. As an indicator that each reporting unit has been valued appropriately through the use of the discounted cash flow valuation model, the aggregate of all reporting unit’s estimated fair value is reconciled to the total market capitalization of the Company.
The Company had 34 reporting units with goodwill as of the first day of the fourth quarter of fiscal 2017, 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, nearly all of the reporting units would continue to have fair values substantially in excess of their respective carrying values.
Management tests indefinite-lived intangible assets for impairment at the asset level, as determined by appropriate asset valuation at the time of acquisition. The impairment test for indefinite-lived intangible assets consists of a comparison between the estimated fair values and carrying values. If the carrying amounts of intangible assets that have indefinite useful lives exceed their estimated fair values, an impairment loss will be recognized in an amount equal to the difference. Management utilizes the royalty savings valuation method to determine the estimated fair value for each indefinite-lived intangible asset. In this method, management estimates the royalty savings arising from the ownership of the intangible asset. The key assumptions used in estimating the royalty savings for impairment testing include discount rates, royalty rates, growth rates, sales projections and terminal value rates. Discount rates used are similar to the rates developed by the WACC methodology considering any differences in company-specific risk factors between reporting units and the indefinite-lived intangible assets. Royalty rates are established by management with the advice of valuation experts and periodically substantiated by valuation experts. Management, considering industry and company-specific historical and projected data, develops growth rates and sales projections for each significant intangible asset. Terminal value rate determination follows common methodology of capturing the present value of perpetual sales estimates beyond the last projected period assuming a constant WACC and low long-term growth rates.
The discounted cash flow and royalty savings valuation methodologies require management to make certain assumptions based upon information available at the time the valuations are performed. Actual results could differ from these assumptions. Management believes the assumptions used are reflective of what a market participant would have used in calculating fair value considering the current economic conditions.
Stock-Based Compensation: The cost of the Company’s stock-based compensation is recorded in accordance with ASC 718, “Stock Compensation.” The Company uses a Black-Scholes-Merton option pricing model to estimate the grant-date fair value of the stock options awarded. The Black-Scholes-Merton model requires assumptions regarding the expected volatility of the Company’s common shares, the risk-free interest rate, the expected life of the stock options award and the Company’s dividend yield. The Company utilizes historical data in determining these assumptions. An increase or decrease in the assumptions or economic events outside of management’s control could have an impact on the Black-Scholes-Merton model.
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.

Acquisition sales represent sales of acquired businesses for the period up to one year subsequent to their acquisition date. The amount of acquisition sales shown in the table above was attributable to the Third Quarter 2017 Acquisitions in fiscal year 2017 and the acquisitions of Y&F/Tactair, DDC and Breeze-Eastern in fiscal year 2016.
The increase in organic sales was primarily driven by commercial aftermarket organic sales increasing by $34.8 million, or 3.0% and defense organic sales increasing by $41.5 million, or 4.4%. Slightly offsetting the increases was commercial OEM organic sales decreasing by $2.8 million, or 0.3%.
Cost of Sales and Gross Profit. Cost of sales increased by $76.4 million, or 5.3%, to $1,519.7 million for the fiscal year ended September 30, 2017 compared to $1,443.3 million for the fiscal year ended September 30, 2016.

Table of Contents

The increase in the dollar amount of cost of sales during the fiscal year ended September 30, 2017 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 2.1 percentage points to 56.6% for the fiscal year ended September 30, 2017 from 54.5% for the fiscal year ended September 30, 2016. The dollar amount of gross profit increased by $256.5 million, or 14.8%, for the fiscal year ended September 30, 2017 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 $153.6 million for the fiscal year ended September 30, 2017, which represented gross profit of approximately 60% of the acquisition sales. The higher gross profit margin on the acquisition sales increased gross profit as a percentage of consolidated sales by approximately 1 percentage point.
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 $94.4 million for the fiscal year ended September 30, 2017.
Gross profit was also improved by the reduction of the impact of inventory purchase accounting adjustments, acquisition integration costs and stock compensation expense charged to cost of sales of approximately $8.5 million.
Selling and Administrative Expenses. Selling and administrative expenses increased by $32.7 million to $415.6 million, or 11.9% of sales, for the fiscal year ended September 30, 2017 from $382.9 million, or 12.1% of sales, for the comparable period last year. Selling and administrative expenses and the related percentage of total sales for the fiscal years ended September 30, 2017 and 2016 were as follows (amounts in millions):

The increase in the dollar amount of selling and administrative expenses during the fiscal year ended September 30, 2017 is primarily due to higher selling and administrative expenses relating to recent acquisitions of approximately $47.7 million, which was approximately 19% of acquisition sales. The increase is partially offset by lower acquisition-related and stock compensation expenses of $19.5 million and $1.4 million, respectively.
Amortization of Intangible Assets. Amortization of intangible assets increased to $89.2 million for the fiscal year ended September 30, 2017 from $77.4 million for the comparable period last year. The net increase of $11.8 million was primarily due to the Third Quarter 2017 Acquisitions and full year amortization recorded from the fiscal 2016 acquisitions of Breeze-Eastern, DDC and Y&F/Tactair.
Refinancing Costs. Refinancing costs of $39.8 million were recorded during the year ended September 30, 2017 representing debt issuance costs expensed in connection with the debt financing activity as disclosed in Note 11, "Debt," to the consolidated financial statements. Included within the $39.8 million was approximately $31.9 million in debt issuance costs and premium related to the repurchase of the 2021 Notes. Refinancing costs of $15.8 million were recorded during the fiscal year ended September 30, 2016 representing debt issuance costs expensed in connection with the debt financing activity in June 2016.
Interest Expense-net. Interest expense-net includes interest on borrowings outstanding, amortization of debt issuance costs, original issue discount and premium, and revolving credit facility fees offset by interest income. Interest expense-net increased $118.7 million, or 24.5%, to $602.6 million for the fiscal year ended September 30, 2017 from $483.9 million for the comparable period last year. The net increase in interest expense-net was primarily due to an increase in the weighted average level of outstanding borrowings, which was approximately $10,993 million for the fiscal year ended September 30, 2017 and approximately $8,834 million for the fiscal year ended September 30, 2016. The weighted average cash interest rate was consistent at 5.3% during the fiscal years ended September 30, 2017 and 2016. The increase in weighted average level of borrowings was due to the issuance of the 2026 Notes for $950 million in June 2016, the incremental term loans of $950 million in June 2016, the additional net debt financing of $641 million in the first fiscal quarter of 2017, the additional 2025 Notes offering of $300 million in the second fiscal

quarter of 2017, the additional $100 million drawn on the trade receivable securitization facility in the fourth quarter of fiscal 2017 and the additional net debt financing of $575 million in the fourth quarter of fiscal 2017. The weighted average interest rate for cash interest payments on total borrowings outstanding at September 30, 2017 was 5.2%.
Income Taxes. Income tax expense as a percentage of income before income taxes was approximately 24.9% for the fiscal year ended September 30, 2017 compared to 23.7% for the fiscal year ended September 30, 2016. The Company’s effective tax rate for these periods was less than the Federal statutory tax rate due primarily to excess tax benefits on equity compensation, foreign earnings taxed at rates lower than the U.S. statutory rates, and the domestic manufacturing deduction. The increase in the effective tax rate for the fiscal year ended September 30, 2017 compared to the fiscal year ended September 30, 2016 was primarily due to foreign earnings taxed at higher rates versus the prior year foreign earnings.
Loss from Discontinued Operations. Loss from discontinued operations is comprised of the operating loss from the Schroth operations that were classified as held-for-sale as of September 30, 2017. The loss includes a $32 million impairment charge to write-down Schroth’s assets to fair value. More detailed information can be found in Note 22, “Discontinued Operations.”
Net Income. Net income increased $10.5 million, or 1.8%, to $596.9 million for the fiscal year ended September 30, 2017 compared to net income of $586.4 million for the year ended September 30, 2016, primarily as a result of the factors referred to above.
Earnings per Share. The basic and diluted earnings per share were $7.88 for the fiscal year ended September 30, 2017 and $10.39 per share for the fiscal year ended September 30, 2016. For the fiscal year ended September 30, 2017, basic and diluted earnings per share from continuing operations were $8.45 and basic and diluted loss per share from discontinued operations were $(0.57). Net income for the fiscal year ended September 30, 2017 of $596.9 million was decreased by dividend equivalent payments of $159.3 million resulting in net income available to common shareholders of $437.6 million. Net income for the fiscal year ended September 30, 2016 of $586.4 million was decreased by dividend equivalent payments of $3.0 million resulting in net income available to common shareholders of $583.4 million. The decrease in earnings per share of $2.51 per share to $7.88 per share is a result of the factors referred to above.

The increase in the dollar amount of cost of sales during the fiscal year ended September 30, 2016 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 0.9 percentage points to 54.5% for the fiscal year ended September 30, 2016 from 53.6% for the fiscal year ended September 30, 2015. The dollar amount of gross profit increased by $278.3 million, or 19.2%, for the fiscal year ended September 30, 2016 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 $171.2 million for the fiscal year ended September 30, 2016, which represented gross profit of approximately 42% 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 $122.6 million for the fiscal year ended September 30, 2016.
Slightly offsetting the increases in gross profit was the impact of higher inventory purchase accounting adjustments acquisition integration costs and stock compensation expense charged to cost of sales of approximately $15.5 million.
Selling and Administrative Expenses. Selling and administrative expenses increased by $61.3 million to $382.9 million, or 12.1% of sales, for the fiscal year ended September 30, 2016 from $321.6 million, or 11.9% of sales, for the comparable period last year.

was approximately 11% of acquisition sales, and higher acquisition-related and stock compensation expenses of $7.3 million and $15.6 million, respectively.
Amortization of Intangible Assets. Amortization of intangible assets decreased to $77.4 million for the fiscal year ended September 30, 2016 from $54.2 million for the comparable period last year. The net increase of $23.2 million was primarily due to the acquisitions of Breeze-Eastern and DDC in fiscal 2016 and full year amortization recorded on the acquisitions made in 2015.
Refinancing Costs. Refinancing costs of $15.8 million were recorded during the fiscal year ended September 30, 2016 representing debt issuance costs expensed in connection with the debt financing activity in June 2016. Included within the $15.8 million was approximately $1.4 million of unamortized debt issuance costs written off. Refinancing costs of $18.4 million were recorded during the fiscal year ended September 30, 2015 representing debt issuance costs expensed in conjunction with the debt financing activity in May 2015. Included within the $18.4 million was approximately $10.2 million of unamortized debt issuance costs written off.
Interest Expense-net. Interest expense-net includes interest on borrowings outstanding, amortization of debt issuance costs and revolving credit facility fees offset by interest income. Interest expense-net increased $65.1 million, or 15.5%, to $483.9 million for the fiscal year ended September 30, 2016 from $418.8 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 $8,834 million for the fiscal year ended September 30, 2016 and approximately $7,827 million for the fiscal year ended September 30, 2015 in addition to a slight increase in the weighted average cash interest rate during the fiscal year ended September 30, 2016 of 5.3% compared to the weighted average cash interest rate during the comparable prior period of 5.2%. The increase in weighted average level of borrowings was primarily due to the issuance of the 2026 Notes for $950.0 million in June 2016, the additional incremental term loans of $950 million in June 2016, the issuance of the 2025 Notes for $450 million in May 2015, and the additional incremental term loan of $1.0 billion in May 2015. The weighted average interest rate for cash interest payments on total borrowings outstanding at September 30, 2016 was 5.2%.
Income Taxes. Income tax expense as a percentage of income before income taxes was approximately 24.9% for the fiscal year ended September 30, 2017 compared to 23.7% for the fiscal year ended September 30, 2016. The Company’s effective tax rate for these periods was less than the Federal statutory tax rate due primarily to excess tax benefits on equity compensation, foreign earning taxed at rates lower than the U.S. statutory rates, and the domestic manufacturing deduction. The decrease in the effective tax rate for the fiscal year ended September 30, 2017 compared to the fiscal year ended September 30, 2016 was primarily due to excess tax benefits on equity compensation and foreign earning taxed at rates lower than the U.S. statutory rates.
Net Income. Net income increased $139.2 million, or 31.1%, to $586.4 million for the fiscal year ended September 30, 2016 compared to net income of $447.2 million for the year ended September 30, 2015, primarily as a result of the factors referred to above.
Earnings per Share. The basic and diluted earnings per share were $10.39 for the fiscal year ended September 30, 2016 and $7.84 per share for the fiscal year ended September 30, 2015. Net income for the fiscal year ended September 30, 2016 of $586.4 million was decreased by dividend equivalent payments of $3.0 million resulting in net income available to common shareholders of $583.4 million. 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. The increase in earnings per share of $2.55 per share to $10.39 per share is a result of the factors referred to above.

Many of the Company’s raw materials and operating expenses are sensitive to the effects of inflation, which could result in changing operating costs. The effects of inflation on the Company’s businesses during the fiscal years 2017, 2016 and 2015 were immaterial.

Liquidity and Capital Resources
We have historically maintained a capital structure comprising a mix of equity and debt financing. We vary our leverage both to optimize our equity return and to pursue acquisitions. We expect to meet our current debt obligations as they come due through internally generated funds from current levels of operations and/or through refinancing in the debt markets prior to the maturity dates of our debt.
We continually evaluate our debt facilities to assess whether they most efficiently and effectively meet the current and future needs of our business. The Company evaluates from time to time the appropriateness of its current leverage, taking into consideration the Company’s debt holders, equity holders, credit ratings, acquisition opportunities and other factors. The Company’s debt leverage ratio, which is computed as total debt divided by EBITDA As Defined for the applicable twelve-month period, has varied widely during the Company’s history, ranging from approximately 3.5 to 7.2. Our debt leverage ratio at September 30, 2017 was approximately 6.9.
If the Company has excess cash, it generally prioritizes allocating the excess cash in the following manner: (1) capital spending at existing businesses, (2) acquisitions of businesses, (3) payment of a special dividend and/or repurchases of our common stock and (4) prepayment of indebtedness or repurchase of debt. Whether the Company undertakes additional common stock repurchases or other aforementioned activities will depend on prevailing market conditions, the Company’s liquidity requirements, contractual restrictions and other factors. The amounts involved may be material. In addition, the Company may issue additional debt if prevailing market conditions are favorable to doing so.
The Company’s ability to make scheduled interest payments on, or to refinance, the Company’s indebtedness, or to fund non-acquisition related capital expenditures and research and development efforts, will depend on the Company’s ability to generate cash in the future. This is subject to general economic, financial, competitive, legislative, regulatory and other factors that are beyond its control.
As a result of the additional debt financing during the fiscal year ended September 30, 2017, interest payments will increase going forward in accordance with the terms of the related debt agreements. However, in connection with the continued 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), we expect our efforts will continue to generate strong margins and provide more than sufficient cash from operating activities to meet our interest obligations and liquidity needs.  We believe our cash from operations and available borrowing capacity will enable us to make opportunistic investments in our own stock, make strategic business combinations and/or pay dividends to our shareholders.
In the future, the Company may increase its borrowings in connection with acquisitions, if cash flow from operating activities becomes insufficient to fund current operations or for other short-term cash needs or for stock repurchases or dividends. Our future leverage will also be impacted by the then current conditions of the credit markets.
Operating Activities. The Company generated $788.7 million of net cash from operating activities during fiscal 2017 compared to $683.3 million during fiscal 2016, a net increase of $105.4 million. The net increase is primarily attributable to an increase in income from continuing operations and items adjusting net income for non-cash expenses and income of $38.8 million, and favorable changes in trade accounts receivable, inventories, and accounts payable of $28.9 million, net.
The change in trade accounts receivable during fiscal 2017 was a use of $54.7 million in cash compared to a use of cash of $80.1 million in fiscal 2016, which is a reduction to the use of cash of $25.4 million year over year. The lower use of cash in fiscal 2017 compared to fiscal 2016 is attributable to the timing of sales and collections on trade accounts receivable.
The change in inventories was a source of cash of $5.1 million in fiscal 2017 compared to a use of cash of $2.1 million in fiscal 2016, which is attributable to increased monitoring of inventory management.
The change in accounts payable during fiscal 2017 was a use of cash of $10.4 million compared to a use of cash of $6.7 million in fiscal 2016. The increase in the use of cash was primarily attributable the timing of payments to vendors.
The Company generated $683.3 million of net cash from operating activities during fiscal 2016 compared to $520.9 million during fiscal 2015. The net increase of $162.4 million was due primarily to an increase in income from continuing operations.
Investing Activities. Net cash used in investing activities was $287.0 million during fiscal 2017 primarily consisting of capital expenditures of $71.0 million, cash paid in connection with the Third Quarter 2017 Acquisitions of $106.3 million, the Schroth acquisition of $79.7 million and the cash settlement of the Breeze-Eastern dissenting shares litigation of $28.7 million. The Company expects its capital expenditures in fiscal year 2018 to be between $85 million and $95 million. The Company’s capital expenditures incurred from year to year are primarily for projects that are consistent with our three core value-driven operating strategies (obtaining profitable new business, continually improve our cost structure and providing highly engineered value-added products to customers).

Table of Contents

Net cash used in investing activities was $1,443.0 million during fiscal 2016 consisting primarily of the acquisitions of Breeze-Eastern, DDC and Y&F/Tactair for a total of $1,399.1 million and capital expenditures of $44.0 million.
Net cash used in investing activities was $1,679.1 million during fiscal 2015 consisting primarily of the acquisitions of Telair Cargo Group, Adams Rite Aerospace GmbH, Pexco Aerospace and PneuDraulics for a total of $1,624.3 million and capital expenditures of $54.9 million.
Financing Activities. Net cash used in financing activities during the fiscal year ended September 30, 2017 was $1,443.7 million. The use of cash was primarily related to the aggregate payment of $2,581.6 million for a $24.00 per share special dividend declared and paid during the first quarter of fiscal 2017 and a $22.00 per share special dividend declared and paid in the fourth quarter of fiscal 2017 and dividend equivalent payments. Also contributing to the use of cash was $1,284.7 million in debt service payments on the existing term loans and the remaining principal on the Tranche C Term Loans, redemption and related premium paid on the 2021 Notes aggregating to $528.8 million and $389.8 million related to treasury stock purchases under the Company's share repurchase program. Slightly offsetting the uses of cash were net proceeds from the 2017 term loans (Tranche F and Tranche G Term Loans) of $2,937.7 million and the additional 2025 Notes offering of $300.4 million, $99.5 million in net proceeds from an additional A/R Securitization draw in the fourth quarter of fiscal 2017 and $21.2 million in proceeds from stock option exercises.
Net cash provided by financing activities during the fiscal year ended September 30, 2016 was $1,632.5 million, which primarily comprised of net proceeds from the 2016 term loans of $1,711.5 million, net proceeds from our 2026 Notes of $939.6 million, and $30.1 million of cash proceeds from the exercise of stock options. These increases were partially offset by $834.4 million of repayments on our existing term loans, $207.8 million in treasury stock purchases under the Company’s share repurchase programs, $3.0 million in dividend equivalent payments and the impact from the adoption of ASU 2016-09 which resulted in the excess tax benefits related to share-based payment arrangements being classified within operating activities beginning in fiscal 2016.
Net cash provided by financing activities during the fiscal year ended September 30, 2015 was $1,054.9 million, which was comprised of $1,516.0 million in net proceeds under our Tranche E Term Loans, $445.3 million of net proceeds from our 2025 Notes, and $123.6 million of cash for tax benefits related to share-based payment arrangements and from the exercise of stock options slightly offset by $1,025.3 million of repayments on our term loans and $3.4 million in dividend equivalent payments.
Description of Senior Secured Term Loans and Indentures
Senior Secured Credit Facilities
On October 14, 2016, the Company entered into the Assumption Agreement with Credit Suisse AG, as administrative agent and collateral agent, and as a lender, in connection with the 2016 term loans. The Assumption Agreement, among other things, provided for (i) additional tranche F term loans in an aggregate principal amount equal to $650 million, which were fully drawn on October 14, 2016, and (ii) additional delayed draw tranche F term loans in an aggregate principal amount not to exceed $500 million, which were fully drawn on October 27, 2016. The terms and conditions that apply to the additional tranche F term loans and the additional delayed draw tranche F term loans are substantially the same as the terms and conditions that apply to the tranche F term loans under the 2016 term loans immediately prior to the Assumption Agreement.
On March 6, 2017, TD Group and certain subsidiaries of TransDigm entered into Amendment No. 2 to the Second Amended and Restated Credit Agreement (“Amendment No. 2”. Refer to Note 11, “Debt,” in the consolidated financial statements included within this Form 10-K for further information regarding the authorized dividends and share repurchases and the increase to the general investment basket established by Amendment No. 2.
On August 22, 2017, the Company entered into Amendment No. 3 and Incremental Term Loan Assumption Agreement to the Second Amended and Restated Credit Agreement (“Amendment No. 3”). Pursuant to Amendment No. 3, TransDigm, among other things, incurred the new tranche G term loans (the “Tranche G Term Loans”) in an aggregate principal amount equal to approximately $1.8 billion and repaid in full all of the Tranche C term loans outstanding under the Restated Credit Agreement. The Tranche G Term Loans were fully drawn on August 22, 2017. The Tranche G Term Loans mature on August 22, 2024. The terms and conditions (other than maturity date) that apply to the Tranche G Term Loans, including pricing, are substantially the same as the terms and conditions that applied to the Tranche C term loans immediately prior to Amendment No. 3. Amendment No. 3 also permitted (a) payment of a special dividend, share repurchase, or combination thereof, in an aggregate amount up to approximately $1.3 billion within 60 days of the effective date of Amendment No. 3, and (b) certain additional restricted payments, including the ability of the Company to declare or pay dividends or repurchase stock, in an aggregate amount not to exceed $1.5 billion within twelve months of the effective date of Amendment No. 3 provided that, among other conditions, if such additional loans are to be used by the Company to repurchase shares of its capital stock, the consolidated secured net debt ratio would be no greater than 4.00 to 1.00 and if such additional terms loans are to be used by TD Group to pay dividends or other distributions on or in respect of its capital stock, the consolidated net leverage ratio would be no greater than 6.00 to 1.00, in each case, after giving effect to such incremental term loans. If any portion of the $1.5 billion is not used for dividends or share repurchases over such twelve month period, such amount (not to exceed $500 million) may be used to repurchase stock at any time thereafter.

LIBO rate is subject to a floor of 0.75%.
The Term Loans Facility requires quarterly aggregate principal payments of $17.5 million. The revolving commitments consist of two tranches which include up to $100 million of multicurrency revolving commitments. At September 30, 2017, the Company had $15.7 million in letters of credit outstanding and $584.3 million in borrowings available under the revolving commitments.
The interest rates per annum applicable to the loans under the Credit Agreement are, at TransDigm’s option, equal to either an alternate base rate or an adjusted LIBO rate for one, two, three or six-month (or to the extent agreed to by each relevant lender, nine or twelve-month) interest periods chosen by TransDigm, in each case plus an applicable margin percentage. The adjusted LIBO rate is subject to a floor of 0.75%. For the fiscal year 2017, the applicable interest rates ranged from approximately 3.75% to 4.26% on the existing term loans.
Under the terms of the Credit Agreement, TransDigm is entitled, on one or more occasions, to request additional term loans or additional revolving commitments to the extent that the existing or new lenders agree to provide such incremental term loans or additional revolving commitments provided that, among other conditions, our consolidated net leverage ratio would be no greater than 7.25 to 1.00 and the consolidated secured net debt ratio would be no greater than 4.25 to 1.00, in each case, after giving effect to such incremental term loans or additional revolving commitments
The Credit Agreement requires mandatory prepayments of principal based on certain percentages of Excess Cash Flow (as defined in the Credit Agreement), commencing 90 days after the end of each fiscal year, subject to certain exceptions. In addition, subject to certain exceptions (including, with respect to asset sales, the reinvestment in productive assets), TransDigm will be required to prepay the loans outstanding under the Credit Agreement at 100% of the principal amount thereof, plus accrued and unpaid interest, with the net cash proceeds of certain asset sales and issuance or incurrence of certain indebtedness. No matters mandating prepayments occurred during the year ended September 30, 2017.
Interest rate swaps and caps used to hedge and offset, respectively, the variable interest rates on the credit facility are described in Note 20, “Derivatives and Hedging Activities” to the consolidated financial statements included herein.

The 2020 Notes, the 2022 Notes, the 2024 Notes, and the 2026 Notes (the “Notes”) were issued at an issue price of 100% of the principal amount. The initial $450 million offering of the 2025 Notes (also considered to be part of the “Notes”) were issued at an issue price of 100% of the principal amount and the subsequent $300 million offering in the quarter ended April 1, 2017 of 2025 Notes (further described below) were issued at an issue price of 101.5% of the principal amount.
Such Notes do not require principal payments prior to their maturity. Interest under the Notes is payable semi-annually. The Notes represent unsecured obligations of TransDigm Inc. ranking subordinate to TransDigm Inc.’s senior debt, as defined in the applicable Indentures.
The Notes are subordinated to all of TransDigm’s existing and future senior debt, rank equally with all of its existing and future senior subordinated debt and rank senior to all of its future debt that is expressly subordinated to the Notes. The Notes are guaranteed on a senior subordinated unsecured basis by TD Group and its wholly-owned domestic subsidiaries named in the indentures. The guarantees of the Notes are subordinated to all of the guarantors’ existing and future senior debt, rank equally with

all of their existing and future senior subordinated debt and rank senior to all of their future debt that is expressly subordinated to the guarantees of the Notes. The Notes are structurally subordinated to all of the liabilities of TD Group’s non-guarantor subsidiaries. The Notes contain many of the restrictive covenants included in the Credit Agreement. TransDigm is in compliance with all the covenants contained in the Notes.
During the first quarter of fiscal 2017, the Company offered to purchase in a cash tender offer all of its previously outstanding 2021 Notes with a portion of the proceeds received from the Incremental Term Loan Assumption Agreement.
During the second quarter of fiscal 2017, the Company issued $300 million in aggregate principal of its 2025 Notes at a premium of 1.5%, resulting in gross proceeds of $304.5 million. The new notes offered were an additional issuance of our existing 2025 Notes and were issued under the same indenture as the original issuance of the $450 million of 2025 Notes. With these additional Notes, there is a total of $750 million in aggregate principal amount of 2025 Notes.
Certain Restrictive Covenants in Our Debt Documents
The Credit Agreement and the Indentures governing the Notes contain restrictive covenants that, among other things, limit the incurrence of additional indebtedness, the payment of dividends, transactions with affiliates, asset sales, acquisitions, mergers and consolidations, liens and encumbrances, and prepayments of certain other indebtedness.
Pursuant to the Credit Agreement, prior to Amendment No. 2 and Amendment No. 3 as described below, and subject to certain conditions, TransDigm was permitted to make certain additional restricted payments, including to declare or pay dividends or repurchase stock, in an aggregate amount not to exceed $1,500 million on or prior to December 31, 2016. Subsequent to December 31, 2016, the aggregate amount of restricted payments remaining, not to exceed $500 million, were permissible solely to the extent that the proceeds were used to repurchase stock. The total restricted payments, as described above, made prior to December 31, 2016 totaled $1,326 million (all related to the special dividend payment and dividend equivalent payments). The remaining $50 million in dividend equivalent payments made in the quarter ended December 31, 2016 were applied against allowable restricted payments that carried over from previous years under our Credit Agreement. During January 2017, $150 million in stock repurchases were made (up to $174 million in stock repurchases were allowable) under this agreement.
On March 6, 2017, TD Group and certain subsidiaries of TransDigm entered into Amendment No. 2. Amendment No. 2 permitted, among other things, up to $1.5 billion of dividends and share repurchases on or prior to March 6, 2018. If any portion of the $1.5 billion was not used for dividends or share repurchases by March 6, 2018, such amount (not to exceed $500 million) may be used to repurchase stock at any time thereafter.
On August 22, 2017, the Company entered into Amendment No. 3. Pursuant to Amendment No. 3, TransDigm, among other things, incurred the Tranche G Term Loans in an aggregate principal amount equal to approximately $1.8 billion and repaid in full all of the Tranche C term loans outstanding under the Credit Agreement. The Tranche G Term Loans were fully drawn on August 22, 2017. The Tranche G Term Loans mature on August 22, 2024. The terms and conditions (other than maturity date) that applied to the Tranche G Term Loans, including pricing, are substantially the same as the terms and conditions that apply to the Tranche C term loans immediately prior to Amendment No. 3. Amendment No. 3 also permitted (a) payment of a special dividend, share repurchase, or combination thereof, in an aggregate amount up to approximately $1.3 billion within 60 days of the effective date of Amendment No. 3, and (b) certain additional restricted payments, including the ability of the Company to declare or pay dividends or repurchase stock, in an aggregate amount not to exceed $1.5 billion within twelve months of the effective date of Amendment No. 3. If any portion of such $1.5 billion is not used for dividends or share repurchases over such twelve month period, such amount (not to exceed $500 million) may be used to repurchase stock at any time thereafter.
In addition, under the Credit Agreement, if the usage of the revolving credit facility exceeds 25% of the total revolving commitments, the Company will be required to maintain a maximum consolidated net leverage ratio of net debt, as defined, to trailing four-quarter EBITDA As Defined. A breach of any of the covenants or an inability to comply with the required leverage ratio could result in a default under the Credit Agreement or the Indentures.
If any such default occurs, the lenders under the Credit Agreement 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 Credit Agreement also have the right in these circumstances to terminate any commitments they have to provide further borrowings. In addition, following an event of default under the Credit Agreement, the lenders thereunder will have the right to proceed against the collateral granted to them to secure the debt, which includes our available cash, and they will also have the right to prevent us from making debt service payments on the Notes.
As of September 30, 2017, the Company was in compliance with all of its debt covenants.

Assumes that the variable interest rate on our Tranche D, Tranche E, Tranche F and Tranche G borrowings under our Senior Secured Term Loans range from approximately 4.37% to 4.92% based on anticipated movements in the LIBO rate. In addition, interest payments include the impact of the existing interest rate swap and cap agreements described in Note 20, “Derivatives and Hedging Activities” to the consolidated financial statements herein.
In addition to the contractual obligations set forth above, the Company incurs capital expenditures for the purpose of maintaining and replacing existing equipment and facilities and, from time to time, for facility expansion. Capital expenditures totaled approximately $71.0 million, $44.0 million, and $54.9 million during fiscal years 2017, 2016, and fiscal 2015, respectively. The Company expects its capital expenditures in fiscal year 2018 to be between $85 million and $95 million.
Off-Balance Sheet Arrangements
The Company utilizes letters of credit to back certain payment and performance obligations. Letters of credit are subject to limits based on amounts outstanding under the Company’s revolving credit facility.
New Accounting Standards
For information about new accounting standards, see Note 4, “Recent Accounting Pronouncements,” to our consolidated financial statements included herein.
Additional Disclosure Required by Indentures
Separate financial statements of TransDigm Inc. are not presented since TD Group has no operations or significant assets separate from its investment in TransDigm Inc. and since the Notes are guaranteed by TD Group and all direct and indirect domestic restricted subsidiaries of TransDigm Inc. TransDigm Inc.’s immaterial wholly owned foreign subsidiaries are not obligated to guarantee the Notes.

ITEM 7A.    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
Interest Rate Risk
Our main exposure to market risk relates to interest rates. Our financial instruments that are subject to interest rate risk principally include fixed-rate and floating-rate long-term debt. At September 30, 2017, we had borrowings under our term loans of approximately $6,973 million that were subject to interest rate risk. Borrowings under our term loans bear interest, at our option, at a rate equal to either an alternate base rate or an adjusted LIBOR for a one-, two-, three- or six-month (or to the extent available to each lender, nine- or twelve-month) interest period chosen by us, in each case, plus an applicable margin percentage. Accordingly, the Company’s cash flows and earnings will be exposed to the market risk of interest rate changes resulting from variable rate borrowings under our term loans. The effect of a hypothetical one percentage point increase in interest rates would increase the annual interest costs under our term loans by approximately $67 million based on the amount of outstanding borrowings at September 30, 2017. The weighted average interest rate on the $6,973 million of borrowings under our term loans on September 30, 2017 was 4.5%.
Interest rate swaps and caps used to hedge and offset, respectively, the variable interest rates on the credit facility are described in Note 20, “Derivatives and Hedging Activities,” to our consolidated financial statements included herein. We do not hold or issue derivative instruments for speculative purposes.
For information about the fair value of the aggregate principal amount of borrowings under our term loans and the fair value of the Notes, see Note 19, “Fair Value Measurements,” to our consolidated financial statements included herein.

ITEM 9A.    CONTROLS AND PROCEDURES
Evaluation of Disclosure Controls and Procedures
As of September 30, 2017, TD Group carried out an evaluation, under the supervision and with the participation of TD Group’s management, including its Chief Executive Officer (Principal Executive Officer) and Chief Financial Officer (Principal Financial Officer), of the effectiveness of the design and operation of TD Group’s disclosure controls and procedures. Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that TD Group’s disclosure controls and procedures are effective to ensure that information required to be disclosed by TD Group in the reports it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified by the Securities and Exchange Commission’s rules and forms, and that such information is accumulated and communicated to TD Group’s management, including its Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, TD Group’s management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management necessarily was required to apply its judgment in designing and evaluating the controls and procedures.
Management’s Report on Internal Control Over Financial Reporting
The management of TD Group is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Exchange Act Rule 13a-15(f). Using criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (COSO) in Internal Control-Integrated Framework, TransDigm’s management assessed the effectiveness of the Company’s internal control over financial reporting as of September 30, 2017. Based on our assessment, management concluded that the Company’s internal control over financial reporting was effective as of September 30, 2017.
During fiscal 2017, we completed the acquisitions of Schroth and the Third Quarter 2017 Acquisitions. The results of operations are included in our consolidated financial statements from the date of acquisition. As permitted by the Securities and Exchange Commission, we have elected to exclude Schroth and the Third Quarter 2017 Acquisitions from our assessment of the effectiveness of our internal control over financial reporting as of September 30, 2017. Total assets as of September 30, 2017 and revenues for the fiscal year ended September 30, 2017 for these fiscal 2017 acquisitions constituted 2% and 1%, respectively, of each of these key measures as reported in our consolidated financial statements.

Table of Contents

The effectiveness of the Company’s internal control over financial reporting as of September 30, 2017 has been audited by Ernst & Young LLP, an independent registered public accounting firm, as stated in their report, which is included elsewhere in this Annual Report on Form 10-K and is incorporated herein by reference.
Changes in Internal Control Over Financial Reporting
There have been no changes in the Company’s internal control over financial reporting that occurred during the fourth quarter of fiscal 2017 that materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

We have audited TransDigm Group Incorporated’s internal control over financial reporting as of September 30, 2017, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). TransDigm Group Incorporated’s management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the company’s internal control over financial reporting based on our audit.
We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with policies and procedures may deteriorate.
As indicated in the accompanying Management’s Report on Internal Control Over Financial Reporting, management’s assessment of and conclusion on the effectiveness of internal control over financial reporting did not include the internal controls of Schroth and the Third Quarter 2017 Acquisitions, which are included in the 2017 consolidated financial statements of TransDigm Group Incorporated and constituted 2% of total assets as of September 30, 2017 and 1% of revenues for the year then ended. Our audit of internal control over financial reporting of TransDigm Group Incorporated also did not include an evaluation of the internal control over financial reporting of Schroth or the Third Quarter 2017 Acquisitions.
In our opinion, TransDigm Group Incorporated maintained, in all material respects, effective internal control over financial reporting as of September 30, 2017, based on the COSO criteria.









 We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of TransDigm Group Incorporated as of September 30, 2017 and 2016, and the related consolidated statements of income, comprehensive income, changes in stockholders’ deficit and cash flows for each of the three years in the period ended September 30, 2017 of TransDigm Group Incorporated and our report dated November 13, 2017 expressed an unqualified opinion thereon.

We have audited the accompanying consolidated balance sheets of TransDigm Group Incorporated as of September 30, 2017 and 2016, and the related consolidated statements of income, comprehensive income, changes in stockholders’ deficit and cash flows for each of the three years in the period ended September 30, 2017. Our audits also included the financial statement schedule listed in the Index at Item 15(a). These financial statements and schedule are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements and schedule based on our audits.
We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.
In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of TransDigm Group Incorporated at September, 30, 2017 and 2016, and the consolidated results of its operations and its cash flows for each of the three years in the period ended September 30, 2017, in conformity with U.S. generally accepted accounting principles. Also, in our opinion, the related financial statement schedule, when considered in relation to the basic financial statements taken as a whole, presents fairly in all material respects the information set forth therein.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), TransDigm Group Incorporated’s internal control over financial reporting as of September 30, 2017, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) and our report dated November 13, 2017, expressed an unqualified opinion thereon.

TRANSDIGM GROUP INCORPORATED
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
1.    DESCRIPTION OF THE BUSINESS
Description of the Business—TransDigm Group Incorporated (“TD Group”), through its wholly-owned subsidiary, TransDigm Inc., is a leading global designer, producer and supplier of highly engineered aircraft components for use on nearly all commercial and military aircraft in service today. TransDigm Inc., along with TransDigm Inc.’s direct and indirect wholly-owned operating subsidiaries (collectively, with TD Group, the “Company” or “TransDigm”), offers a broad range of proprietary aerospace components. TD Group has no significant assets or operations other than its 100% ownership of TransDigm Inc. TD Group’s common stock is listed on the New York Stock Exchange, or the NYSE, under the trading symbol “TDG.”
Major 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, databus and power controls, 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, high performance hoists, winches and lifting devices, and cargo loading, handling and delivery systems.
2.    ACQUISITIONS
During the last three fiscal years, the Company completed the acquisitions of Schroth, Y&F/Tactair, DDC, Breeze-Eastern, PneuDraulics, Pexco Aerospace, Adams Rite Aerospace GmbH and Telair Cargo Group. Additionally, during the third quarter of fiscal 2017, the Company acquired three separate aerospace product lines (collectively, the “Third Quarter 2017 Acquisitions”). The Company accounted for the acquisitions using the acquisition method and included the results of operations of the acquisitions in its consolidated financial statements from the effective date of each acquisition. As of September 30, 2017, the one-year measurement period is open for Schroth and the Third Quarter 2017 Acquisitions and therefore the assets acquired and liabilities assumed related to these acquisitions are subject to adjustment until the end of the respective one-year measurement period. The Company is in the process of obtaining a third-party valuation of certain tangible and intangible assets of the Third Quarter 2017 Acquisitions; therefore, the values attributed to those acquired assets and liabilities in the consolidated financial statements are subject to adjustment. Pro forma net sales and results of operations for the acquisitions, had they occurred at the beginning of the applicable fiscal year ended September 30, 2017 or 2016, are not material and, accordingly, are not provided.
The acquisitions strengthen and expand the Company’s position to design, produce and supply highly engineered proprietary aerospace components in niche markets with significant aftermarket content and provide opportunities to create value through the application of our three core value-driven operating strategies (obtaining profitable new business, improving our cost structure, and providing highly engineered value-added products to customers). The purchase price paid for each acquisition reflects the current earnings before interest, taxes, depreciation and amortization (EBITDA) and cash flows, as well as the future EBITDA and cash flows expected to be generated by the business, which are driven in most cases by the recurring aftermarket consumption over the life of a particular aircraft, estimated to be approximately 25 to 30 years.
Third Quarter 2017 Acquisitions – During the third quarter of fiscal 2017, the Company acquired the Third Quarter 2017 Acquisitions for a total purchase price of approximately $106.3 million in cash, which includes working capital settlements totaling $1.0 million paid in the third and fourth quarter of 2017. All three product lines consist primarily of proprietary, sole source products with significant aftermarket content. The products include highly engineered aerospace controls, quick disconnect couplings, and communication electronics. Each product line acquired was consolidated into an existing TransDigm reporting unit within TransDigm's Power & Control segment. The Company expects that approximately $62 million of goodwill recognized for the acquisitions will be deductible for tax purposes over 15 years and approximately $9 million of goodwill recognized for the acquisitions will not be deductible for tax purposes.
Schroth – On February 22, 2017, the Company acquired all of the outstanding stock of Schroth Safety Products GmbH and certain aviation and defense assets and liabilities from subsidiaries of Takata Corporation (collectively, "Schroth"), for a total purchase price of approximately $89.7 million, of which $79.7 million was paid in cash (including a working capital settlement of $0.8 million paid in the third quarter of 2017) and the remaining approximately $10.0 million of which is accrued primarily related to an indemnity holdback to be settled within the one-year measurement period.
In connection with the settlement of a Department of Justice investigation into the competitive effects of the acquisition, during the fourth quarter of 2017, the Company committed to dispose of the Schroth business.  Therefore, Schroth was classified as held-for-sale as of September 30, 2017. The results of operations of Schroth are reflected as discontinued operations in the accompanying consolidated financial statements. Schroth designs and manufactures proprietary, highly engineered, advanced

F-7

Table of Contents

safety systems for aviation, racing and military ground vehicles around the world. Prior to being classified as discontinued operations, Schroth was included in TransDigm's Airframe segment.
The loss from discontinued operations in the consolidated statements of income includes a $32.0 million impairment charge to write down Schroth’s assets to estimated fair value. The impairment charge recorded in the fourth quarter of 2017 was based on an internal assessment around the recovery of the Schroth assets.  Schroth’s assets have been recorded at fair value in the consolidated balance sheet as of September 30, 2017. Further disclosure related to Schroth’s discontinued operations is included in Note 22.
Y&F/Tactair – On September 23, 2016, the Company acquired all of the outstanding stock of Young & Franklin, Inc., the parent company of Tactair Fluid Controls, Inc., for approximately $258.8 million in cash, which includes a working capital settlement of $2.7 million paid in the first quarter of 2017. Y&F/Tactair manufactures proprietary, highly engineered valves and actuators. Y&F/Tactair is included in TransDigm’s Power & Control segment. The purchase price includes approximately $74.5 million of tax benefits being realized by the Company over a 15-year period that began in the first quarter of fiscal 2017. The Company expects that approximately $124 million of goodwill recognized for the acquisition will be deductible for tax purposes over 15 years and approximately $8 million of goodwill recognized for the acquisition will not be deductible for tax purposes.
Data Device Corporation – On June 23, 2016, the Company acquired all of the outstanding stock of ILC Holdings, Inc., the parent company of Data Device Corporation, for a total purchase price of approximately $997.7 million in cash, which includes a working capital settlement of $1.4 million received in the first quarter of fiscal 2017. TransDigm financed the acquisition of DDC with cash proceeds from the issuance of senior subordinated notes due in June 2026 and term loans.

3.    SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Basis of Presentation and Consolidation—The accompanying consolidated financial statements were prepared in conformity with generally accepted accounting principles in the United States (“GAAP”) and include the accounts of TD Group and subsidiaries. All significant intercompany balances and transactions have been eliminated. Certain reclassifications have been made to the current period annual and interim final statements as during the fourth quarter of 2017, the Company committed to disposing of Schroth. As of September 30, 2017, Schroth was classified as held-for-sale and the results of operations for Schroth are reflected as discontinued operations in the accompanying consolidated financial statements. Refer to Note 22, “Discontinued Operations,” for further information.
Revenue Recognition and Related Allowances—Revenue is recognized from the sale of products when title and risk of loss passes to the customer, which is generally at the time of shipment. Substantially all product sales are made pursuant to firm, fixed-price purchase orders received from customers. Provisions for estimated returns, uncollectible accounts and the cost of repairs under contract warranty provisions are provided for in the same period as the related revenues are recorded and are principally based on historical results modified, as appropriate, by the most current information available. Due to uncertainties in the estimation process, it is possible that actual results may vary from the estimates.
Shipping and Handling Costs—Shipping and handling costs are included in cost of sales in the consolidated statements of income.
Research and Development Costs—The Company expenses research and development costs as incurred and classifies such amounts in selling and administrative expenses. The expense recognized for research and development costs for the years ended September 30, 2017, 2016 and 2015 was approximately $73.8 million, $58.6 million, and $48.3 million, respectively.
Cash Equivalents—The Company considers all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents.
Allowance for Uncollectible Accounts—The Company reserves for amounts determined to be uncollectible based on specific identification of losses and estimated losses based on historical experience. The allowance also incorporates a provision for the estimated impact of disputes with customers. The determination of the amount of the allowance for doubtful accounts is subject to significant levels of judgment and estimation by management. If circumstances change or economic conditions deteriorate or improve, the allowance for doubtful accounts could increase or decrease.

Inventories—Inventories are stated at the lower of cost or market. Cost of inventories is 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. Provision for potentially obsolete or slow-moving inventory is made based on management’s analysis of inventory levels and future sales forecasts.
Property, Plant and Equipment—Property, plant and equipment are stated at cost and include improvements which significantly increase capacities or extend the useful lives of existing plant and equipment. Depreciation is computed using the straight-line method over the following estimated useful lives: land improvements from 10 to 20 years, buildings and improvements from 5 to 30 years, machinery and equipment from 2 to 10 years and furniture and fixtures from 3 to 10 years. Net gains or losses related to asset dispositions are recognized in earnings in the period in which dispositions occur. Routine maintenance, repairs and replacements are expensed as incurred.
Property, plant and equipment is assessed for potential impairment whenever indicators of impairment are present by determining whether the carrying value of the property can be recovered through projected, undiscounted cash flows from future operations over the property’s remaining estimated useful life. Any impairment recognized is the amount by which the carrying amount exceeds the fair value of the asset. Fair value is measured based on quoted market prices in active markets, if available. If quoted market prices are not available, the estimate of fair value is based on various valuation techniques, including the discounted value of estimated future cash flows.
Debt Issuance Costs, Premiums and Discounts—The cost of obtaining financing as well as premiums and discounts are amortized using the effective interest method over the terms of the respective obligations as a component of interest expense within the consolidated statements of income. Debt issuance costs are presented in the consolidated balance sheets as a direct reduction from the carrying amount of the related debt liabilities.
Intangible Assets—Intangible assets consist of identifiable intangibles acquired or recognized in accounting for the acquisitions (trademarks, trade names, technology, order backlog and other intangible assets) and goodwill. Goodwill and intangible assets that have indefinite useful lives (i.e., trademarks and trade names) are subject to annual impairment testing. Management determines fair value using a discounted future cash flow analysis or other accepted valuation techniques. The Company performs an annual impairment test for goodwill and other intangible assets as of the first day of the fourth fiscal quarter of each year, or more frequently, if an event occurs or circumstances change that would more likely than not reduce fair value below current value.
At the time of goodwill impairment testing, the Company first assesses qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount, and whether it is therefore necessary to perform the quantitative goodwill impairment test. The quantitative goodwill impairment test consists of two steps. The first step of the goodwill impairment test, used to identify potential impairment, compares the fair value of a reporting unit (as defined) with its carrying amount, including goodwill. If the fair value of the reporting unit exceeds its carrying amount, goodwill is not considered impaired, and the second step of the goodwill impairment test is unnecessary. The second step measures the amount of impairment, if any, by comparing the carrying value of the goodwill associated with a reporting unit to the implied fair value of the goodwill derived from the estimated overall fair value of the reporting unit and the individual fair values of the other assets and liabilities of the reporting unit.
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.
The impairment test for indefinite lived intangible assets consists of a comparison between their fair values and carrying values. If the carrying amounts of intangible assets that have indefinite useful lives exceed their fair values, an impairment loss will be recognized in an amount equal to the sum of any such excesses.
The Company assesses the recoverability of its amortizable intangible assets only when indicators of impairment are present by determining whether the amortization over their remaining lives can be recovered through projected, undiscounted cash flows from future operations. Amortization of amortizable intangible assets is computed using the straight-line method over the following estimated useful lives: technology from 20 to 22 years, order backlog over one year, and other intangible assets over 20 years.
Stock-Based Compensation—The Company records stock-based compensation expense using the fair value method of accounting. Compensation expense is recorded over the vesting periods of the stock options, restricted stock and other stock-based incentives. No expense is recognized for any stock options, restricted stock and other stock-based incentives ultimately forfeited because the recipients fail to meet vesting requirements.
Income Taxes—The Company accounts for income taxes using an asset and liability approach. Deferred taxes are recorded for the difference between the book and tax basis of various assets and liabilities. A valuation allowance is provided when it is more likely than not that some or all of a deferred tax asset will not be realized.

Contingencies—During the ordinary course of business, the Company is from time to time threatened with, or may become a party to, legal actions and other proceedings. While the Company is currently involved in certain legal proceedings, it believes the results of these proceedings will not have a material adverse effect on its financial condition, results of operations, or cash flows.
Estimates—The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Comprehensive Income (Loss)—The term “comprehensive income (loss)” represents the change in stockholders’ equity (deficit) from transactions and other events and circumstances resulting from non-stockholder sources. The Company’s accumulated other comprehensive income or loss, consisting principally of fair value adjustments to its interest rate swap and cap agreements (net of tax), cumulative foreign currency translation adjustments and pension liability adjustments (net of tax), is reported separately in the accompanying consolidated statements of comprehensive income.
Foreign Currency Translation and Transactions—The assets and liabilities of subsidiaries located outside the United States are translated into U.S. dollars at the rates of exchange in effect at the balance sheet dates. Revenue and expense items are translated at the average monthly exchange rates prevailing during the period. Gains and losses resulting from foreign currency transactions are recognized currently in income, and those resulting from translation of financial statements are accumulated as a separate component of other comprehensive income (loss) for the period. Foreign currency gains or losses recognized currently in income from changes in exchange rates were immaterial to our results of operations.
Earnings per Share—Earnings per share information is determined using the two-class method, which includes the weighted-average number of common shares outstanding during the period and other securities that participate in dividends (“participating securities”). Our vested stock options are considered “participating securities” because they include non-forfeitable rights to dividends. In applying the two-class method, earnings are allocated to both common stock shares and participating securities based on their respective weighted-average shares outstanding for the period. Diluted earnings per share information may include the additional effect of other securities, if dilutive, in which case the dilutive effect of such securities is calculated using the treasury stock method. Contingently issuable shares are not included in earnings per share until the period in which the contingency is satisfied; therefore, basic and diluted earnings per share are the same.
4.    RECENT ACCOUNTING PRONOUNCEMENTS
In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, which creates a new topic in the Accounting Standards Codification (“ASC”) 606, “Revenue From Contracts With Customers.” In addition to superseding and replacing nearly all existing U.S. GAAP revenue recognition guidance, including industry-specific guidance, ASC 606 establishes a new control-based revenue recognition model; changes the basis for deciding when revenue is recognized over time or at a point in time; provides new and more detailed guidance on specific topics; and expands and improves disclosures about revenue. The new revenue standards may be applied retrospectively to each prior period presented or retrospectively with the cumulative effect recognized as of the date of adoption. The guidance is effective for the Company for annual reporting periods, including interim periods therein, beginning October 1, 2018, which is the Company’s planned date of adoption. The Company preliminarily expects to use the full retrospective method. The Company is continuing to evaluate the impact of the standard, and the planned adoption method is subject to change. For each reporting unit, we have evaluated a representative sample of contracts and other agreements with our customers and evaluated the provisions contained within these contracts and agreements in consideration of the five step model specified within ASC 606. We are in the process of documenting the impact of the standard on our current accounting policies and practices in order to identify material differences, if any, that would result from applying the new requirements to our revenue contracts. We continue to make progress on our assessment of ASC 606 and are also in the process of evaluating the impact, if any, on changes to our business processes, systems, and controls to support recognition and disclosure requirements under ASC 606.
In September 2015, the FASB issued ASU 2015-16, "Simplifying the Accounting for Measurement-Period Adjustments," a new standard intended to simplify the accounting for measurement period adjustments in a business combination. Measurement period adjustments are changes to provisional amounts recorded when the accounting for a business combination is incomplete as of the end of a reporting period. The measurement period can extend for up to a year following the transaction date. During the measurement period, companies may make adjustments to provisional amounts when information necessary to complete the measurement is received. The new guidance requires companies to recognize these adjustments, including any related impacts to net income, in the reporting period in which the adjustments are determined. Companies are no longer required to retroactively apply measurement period adjustments to all periods presented. The guidance was effective for the Company on October 1, 2016. However, as early adoption was permissible, the Company adopted the pronouncement beginning October 1, 2015. The adoption of this standard did not have a significant impact on its consolidated financial statements and disclosures.

In February 2016, the FASB issued ASU 2016-02, “Leases (ASC 842),” which will require that a lessee recognize assets and liabilities on the balance sheet for all leases with a lease term of more than twelve months, with the result being the recognition of a right of use asset and a lease liability.  The guidance is effective for the Company for annual reporting periods, including interim periods therein, beginning October 1, 2019, with early adoption permitted.  The Company is currently evaluating the impact of adopting this standard on its consolidated financial statements and disclosures.
In March 2016, the FASB issued ASU 2016-09, “Improvements to Employee Share-Based Payment Accounting.” The guidance requires the recognition of the income tax effects of awards in the income statement when the awards vest or are settled, thus eliminating additional paid in capital pools. The guidance also allows for the employer to repurchase more of an employee’s shares for tax withholding purposes without triggering liability accounting. In addition, the guidance allows for a policy election to account for forfeitures as they occur rather than on an estimated basis. ASU 2016-09 was effective for the Company for annual reporting periods, including interim periods therein, beginning October 1, 2017, with early adoption permitted. As early adoption is permissible, the Company adopted this standard in the fourth quarter of fiscal 2016. Changes were applied prospectively in accordance with the standard and prior periods were not adjusted. In addition, the Company continued to account for forfeitures on an estimated basis.
In June 2016, the FASB issued ASU 2016-13, "Financial Instruments—Credit Losses: Measurement of Credit Losses on Financial Instruments (ASU 2016-13)," which changes the impairment model for most financial assets. The new model uses a forward-looking expected loss method, which will generally result in earlier recognition of allowances for losses. ASU 2016-13 is effective for annual and interim periods beginning after December 15, 2019 and early adoption is permitted for annual and interim periods beginning after December 15, 2018. The Company is currently evaluating the impact of adopting this standard on its consolidated financial statements and disclosures.
In August 2016, the FASB issued ASU 2016-15, "Statement of Cash Flows—Classification of Certain Cash Receipts and Cash Payments," which clarifies existing guidance related to accounting for cash receipts and cash payments and classification on the statement of cash flows. This guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017, with early adoption permitted. The Company elected to early adopt this standard in the fourth quarter of fiscal 2017. The adoption of this standard did not have a significant impact on its consolidated statement of cash flows.
In January 2017, the FASB issued ASU 2017-04, “Simplifying the Test for Goodwill Impairment,” to eliminate Step 2 from the goodwill impairment test in order to simplify the subsequent measurement of goodwill. The guidance is effective for fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The adoption of this standard is not expected to have a material impact on its consolidated financial statements and disclosures.
In May 2017, the FASB issued ASU 2017-09, "Compensation—Stock Compensation (ASC 718): Scope of Modification Accounting," which provides clarity on which changes to the terms or conditions of share-based payment awards require an entity to apply the modification accounting provisions required in ASC 718. The standard is effective for all entities for annual periods beginning after December 15, 2017, with early adoption permitted, including adoption in any interim period for which financial statements have not yet been issued. The adoption of this standard is not expected to have a material impact on its consolidated financial statements and disclosures.
In August 2017, the FASB issued ASU 2017-12, “Derivatives and Hedging (ASC 815): Targeted Improvements to Accounting for Hedging Activities,” which amends the FASB’s hedge accounting model to enable entities to better portray their risk management activities in financial statements. The guidance eliminates the requirement to separately measure and report hedge ineffectiveness and generally requires the entire change in the fair value of a hedging instrument to be presented in the same income statement line as the hedged item. The guidance also eases certain documentation and assessment requirements and modifies the accounting for components excluded from the assessment of hedge effectiveness. This guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018, and early adoption is permitted. The Company is currently evaluating the impact of adopting this standard on its consolidated financial statements and disclosures.

Trade Receivable Securitization Facility
During fiscal 2014, the Company established a trade receivable securitization facility (the “Securitization Facility”). The Securitization Facility effectively increases the Company’s borrowing capacity depending on the amount of the domestic operations’ trade accounts receivable. The Securitization Facility includes the right for the Company to exercise annual one year extensions as long as there have been no termination events as defined by the agreement. The Company uses the proceeds from the Securitization Facility as an alternative to other forms of debt, effectively reducing borrowing costs. In August 2017, the Company amended the Securitization Facility to increase the borrowing capacity to $300 million and extend the maturity date to August 1, 2018. As of September 30, 2017, the Company has borrowed $300 million under the Securitization Facility. The Securitization Facility is collateralized by substantially all of the Company’s domestic operations’ trade accounts receivable.
Repurchase of Senior Subordinated Notes due 2021
On October 13, 2016, the Company announced a cash tender offer for any and all of its outstanding 2021 Notes. On October 27, 2016, the Company redeemed a principal amount of approximately $158 million in 2021 Notes outstanding for total consideration of $1,060.50 (plus accrued and unpaid interest) for each $1,000 aggregate principal amount. The total consideration included an early tender premium of $30.00 per $1,000 principal amount of 2021 Notes payable only with respect to each note validly tendered and not revoked on or before October 26, 2016. On November 28, 2016, pursuant to the terms of the indenture governing the 2021 Notes, the Company redeemed the remaining principal of $342 million in 2021 Notes outstanding at a redemption price of 105.625% of the principal amount (plus accrued and unpaid interest).
The Company recorded refinancing costs of $31.9 million during the fiscal year ended September 30, 2017 representing debt issuance costs expensed in conjunction with the redemption of the 2021 Notes. The costs consisted of the premium of $28.8 million paid to redeem the $500 million of 2021 Notes and the write-off of $3.1 million in unamortized debt issuance costs.
Incremental Term Loan Assumption Agreement
On October 14, 2016, the Company entered into an Incremental Term Loan Assumption Agreement (the “Assumption Agreement”) with Credit Suisse AG, as administrative agent and collateral agent, and as a lender, in connection with the 2016 term loans. The Assumption Agreement, among other things, provides for (i) additional tranche F term loans in an aggregate principal amount equal to $650 million, which were fully drawn on October 14, 2016, and (ii) additional delayed draw tranche F term loans in an aggregate principal amount not to exceed $500 million, which were fully drawn on October 27, 2016, the proceeds of which were used to repurchase the Company's 2021 Notes. The terms and conditions that apply to the additional tranche F term loans and the additional delayed draw tranche F term loans are substantially the same as the terms and conditions that apply to the tranche F term loans under the 2016 term loans immediately prior to the Assumption Agreement.
The Company capitalized $11.3 million and expensed $0.2 million in refinancing costs associated with the Assumption Agreement during the fiscal year ended September 30, 2017.
Issuance of Senior Subordinated Notes
On March 1, 2017, TransDigm Inc. issued $300 million in aggregate principal amount of its 2025 Notes at an issue price of 101.5% of the principal amount. The new notes offered were an additional issuance to our existing $450 million of 2025 Notes. The new notes offered, together with the existing 2025 Notes, are treated as a single class for all purposes under the indenture.
The 2025 Notes bear interest at the rate of 6.5% per annum, which accrues from November 15, 2016 and is payable semiannually in arrears on May 15 and November 15 of each year, commencing on May 15, 2017. The 2025 Notes mature on May 15, 2025, unless earlier redeemed or repurchased, and are subject to the terms and conditions set forth in the indentures governing the 2025 Notes.
In addition to the premium of $4.5 million recorded upon the issuance of the additional $300 million of 2025 Notes, the Company capitalized $0.4 million and expensed $3.7 million in refinancing costs representing fees associated with the issuance of the additional $300 million of 2025 Notes during the fiscal year ended September 30, 2017.
Amendment No. 2 to the Second Amended and Restated Credit Agreement
On March 6, 2017, TD Group and certain subsidiaries of TransDigm entered into Amendment No. 2 to the Second Amended and Restated Credit Agreement, dated June 4, 2014, with Credit Suisse AG, as administrative agent and collateral agent (the "Agent"), and the other agents and lenders named therein. Amendment No. 2 permits, among other things, up to $1.5 billion of dividends and share repurchases over twelve months. If any portion of the $1.5 billion is not used for dividends or share repurchases over the twelve month period, such amount (not to exceed $500 million) may be used to repurchase stock at any time thereafter. Amendment No. 2 also increased the general investment basket to the greater of $400 million and 8% of consolidated total assets.
The Company capitalized $10.3 million and expensed $0.3 million in refinancing costs representing fees associated with Amendment No. 2 during the fiscal year ended September 30, 2017.

Amendment No. 3 to the Second Amended and Restated Credit Agreement
On August 22, 2017, the Company entered into Amendment No. 3 to the Second Amended and Restated Credit Agreement. Pursuant to Amendment No. 3, TransDigm, among other things, incurred new Tranche G Term Loans in an aggregate principal amount equal to approximately $1.8 billion and repaid in full all of the Tranche C term loans outstanding under the Credit Agreement. The Tranche G Term Loans were fully drawn on August 22, 2017. The Tranche G Term Loans mature on August 22, 2024. The terms and conditions (other than maturity date) that apply to the Tranche G Term Loans, including pricing, are substantially the same as the terms and conditions that apply to the Tranche C term loans immediately prior to Amendment No. 3. Amendment No. 3 also permitted (a) payment of a special dividend, share repurchase, or combination thereof, in an aggregate amount up to approximately $1.3 billion within 60 days of the effective date of Amendment No. 3, and (b) certain additional restricted payments, including the ability of the Company to declare or pay dividends or repurchase stock, in an aggregate amount not to exceed $1.5 billion within twelve months of the effective date of Amendment No. 3 and is subject to 6.0x consolidated net leverage ratio for dividends and 4.0x consolidated secured net debt ratio for share repurchases. If any portion of the $1.5 billion is not used for dividends or share repurchases over such twelve month period, such amount (not to exceed $500 million) may be used to repurchase stock at any time thereafter.
The Company capitalized $7.1 million representing fees associated with Amendment No. 3 during the fiscal year ended September 30, 2017.
The Company capitalized $16.5 million and expensed $2.2 million in refinancing costs representing debt issuances costs associated with the Tranche G Term Loans during the fiscal year ended September 30, 2017. Additionally, the Company wrote-off $1.5 million in unamortized debt issuance costs related to the Tranche C Term Loans.

12.    RETIREMENT PLANS
Defined Contribution PlansThe Company sponsors certain defined contribution employee savings plans that cover substantially all of the Company’s non-union employees. Under certain plans, the Company contributes a percentage of employee compensation and matches a portion of employee contributions. The cost recognized for such contributions for the years ended September 30, 2017, 2016 and 2015 was approximately $14.6 million, $12.7 million and $9.9 million, respectively.
Defined Benefit Pension PlansThe Company maintains certain non-contributory defined benefit pension plans. The Company’s funding policy is to contribute actuarially determined amounts allowable under tax and statutory regulations for the qualified plans. The Company uses a September 30th measurement date for its defined benefit pension plans.
The Company maintains certain qualified, non-contributory defined benefit pension plans, which together cover certain union employees. The plans provide benefits of stated amounts for each year of service. The plan assets as of September 30, 2017 and 2016 were approximately $69.9 million and $67.0 million, respectively. The Company’s projected benefit obligation for these defined benefit pension plans at September 30, 2017 and 2016 was $91.7 million and $100.6 million, respectively. The total liability recognized at September 30, 2017 and 2016 was $21.8 million and $33.6 million, respectively. The decrease in the total liability at September 30, 2017 compared to September 30, 2016 is primarily attributable to the change in pension assumptions, particularly a higher discount rate and expected rate of return on assets, for the AmSafe Bridport Limited pension plan.
The net periodic pension cost recognized in the consolidated statements of income for the years ended September 30, 2017, 2016, and 2015 was $1.7 million, $1.0 million, and $0.6 million, respectively.

Unrecognized tax benefits at September 30, 2017 and 2016, the recognition of which would have an effect on the effective tax rate for each fiscal year, amounted to $8.7 million in each period. The Company classifies all income tax related interest and penalties as income tax expense, which were not significant for the years ended September 30, 2017, 2016 and 2015. As of September 30, 2017 and 2016, the Company accrued $1.2 million and $1.1 million, respectively, for the potential payment of interest and penalties. The Company anticipates no significant changes to its total unrecognized tax benefits through fiscal 2017.
14.    ENVIRONMENTAL LIABILITIES
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 Company also takes into consideration the estimated period of time in which payments will be required. 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 offset 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.
The Company’s consolidated balance sheets includes environmental remediation obligations at September 30, 2017 and 2016 of $39.9 million and $46.1 million, respectively.
15.    CAPITAL STOCK
TD Group consists of 224,400,000 shares of $.01 par value common stock and 149,600,000 shares of $.01 par value preferred stock. The total number of shares of common stock issued at September 30, 2017 and 2016 was 56,093,659 and 55,767,767, respectively. The total number of shares held in treasury at September 30, 2017 and 2016 were 4,159,207 and 2,433,035, respectively. There were no shares of preferred stock outstanding at September 30, 2017 and 2016. The terms of the preferred stock have not been established.
The Board of Directors has previously authorized a common share repurchase program, which has been subject to amendments. On January 26, 2017, our Board of Directors increased the authorized amount of repurchases allowable under the stock program from $450 million to $472 million. The increase in the allowable repurchases under the stock repurchase program aligned the program with the restricted payments allowable under the Credit Agreement. On March 7, 2017, our Board of Directors authorized a new stock repurchase program replacing the $472 million program permitting repurchases of a portion of outstanding shares not to exceed $600 million in the aggregate, subject to any restrictions specified in the Credit Agreement and/or Indentures governing the existing Notes.
During the fiscal year ended September 30, 2017, in the aggregate, the Company repurchased 1,723,624 shares at a cost of $389.8 million at the weighted average cost of $226.16 under its stock repurchase programs.
As of September 30, 2017, the remaining amount of repurchases allowable under the $600 million program was $360.2 million subject to any restrictions specified in the Credit Agreement and/or Indentures governing the existing Notes.
On November 8, 2017, our Board of Directors, authorized a new stock repurchase program replacing the $600 million program permitting repurchases of our outstanding shares not to exceed $650 million in the aggregate, subject to any restrictions specified in the Credit Agreement and/or Indentures governing the existing Notes.

Table of Contents

The primary measurement used by management to review and assess the operating performance of each segment is EBITDA As Defined. The Company defines EBITDA As Defined as earnings before interest, taxes, depreciation and amortization plus certain non-operating items recorded as corporate expenses including refinancing costs, acquisition-related costs, transaction-related costs and non-cash compensation charges incurred in connection with the Company’s stock option plans. Acquisition-related costs represent accounting adjustments to inventory associated with acquisitions of businesses and product lines that were charged to cost of sales when the inventory was sold; costs incurred to integrate acquired businesses and product lines into the Company’s operations, facility relocation costs and other acquisition-related costs; transaction related costs comprising deal fees; legal, financial and tax diligence expenses and valuation costs that are required to be expensed as incurred and other acquisition accounting adjustments.
EBITDA As Defined is not a measurement of financial performance under GAAP. Although the Company uses EBITDA As Defined to assess the performance of its business and for various other purposes, the use of this non-GAAP financial measure as an analytical tool has limitations, and it should not be considered in isolation or as a substitute for analysis of the Company’s results of operations as reported in accordance with GAAP.
The Company’s segments are reported on the same basis used internally for evaluating performance and for allocating resources. The accounting policies for each segment are the same as those described in the summary of significant accounting policies in the Company’s consolidated financial statements. Intersegment sales and transfers are recorded at values based on market prices, which creates intercompany profit on intersegment sales or transfers that is eliminated in consolidation. Intersegment sales were insignificant for the periods presented below. Certain corporate-level expenses are allocated to the operating segments.

17.    STOCK-BASED COMPENSATION
The Company’s stock compensation plans are designed to assist the Company in attracting, retaining, motivating and rewarding key employees, directors or consultants, and promoting the creation of long-term value for stockholders by closely aligning the interests of these individuals with those of the Company’s stockholders. The Company’s stock compensation plans provide for the granting of stock options, restricted stock and other stock-based incentives.
Non-cash stock compensation expense recognized by the Company during the years ended September 30, 2017, 2016 and 2015 was $45.5 million, $48.3 million and $31.5 million, respectively.
The weighted-average grant date fair value of options granted during the fiscal years ended September 30, 2017, 2016 and 2015 was $67.11, $57.47 and $65.57, respectively.
Compensation expense is recognized based upon probability assessments of awards that are expected to vest in future periods. Such probability assessments are subject to revision and, therefore, unrecognized compensation expense is subject to future changes in estimate. As of September 30, 2017, there was approximately $52.4 million of total unrecognized compensation expense related to non-vested awards expected to vest, which is expected to be recognized over a weighted-average period of 2.6 years.

The fair value of the Company’s employee stock options was estimated at the date of grant using a Black-Scholes-Merton option-pricing model with the following weighted average assumptions for all options granted during the fiscal years ended:
 
Fiscal Years Ended September 30,
 
2017

2015
Risk-free interest rate

Expected dividend yield of stock
 
 
Expected volatility of stock

35%
The risk-free interest rate is based upon the Treasury bond rates as of the grant date. The average expected life of stock-based awards is based on the Company’s actual historical exercise experience. Expected volatility of stock was calculated using a rate based upon the historical volatility of TransDigm’s common stock. Notwithstanding the special cash dividends declared and paid from time to time, the Company historically has not declared and paid regular cash dividends and does not anticipate declaring and paying regular cash dividends in future periods; thus, no dividend rate assumption is used.
The total fair value of options vested during fiscal years ended September 30, 2017, 2016 and 2015 was $42.9 million, $36.6 million and $14.9 million, respectively.
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 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.
Performance Vested Stock Options—All of the options granted through September 30, 2017 under the 2014 stock option plan have been pursuant to an equity incentive program adopted by the Company in 2008. Under the 2008 equity incentive program, all of the options granted will vest based on the Company’s achievement of established operating performance goals.

2006 Stock Incentive Plan
In conjunction with the consummation of the Company’s initial public offering, a 2006 stock incentive plan was adopted by TD Group. In July 2008 and March 2011, the plan was amended to increase the number of shares available for issuance thereunder. TD Group reserved 8,119,668 shares of its common stock for issuance to key employees, directors or consultants under the plan. Awards under the plan may be in the form of options, restricted stock or other stock-based awards. Options granted under the plan will expire no later than the tenth anniversary of the applicable date of grant of the options, and will have an exercise price of not less than the fair market value of our common stock on the date of grant. Restricted stock granted under the plan vests over three years.
Restricted Stock—The Company granted 17,700 restricted stock units with a weighted-average grant date fair value of $189.97 during the fiscal year ended September 30, 2015.

2003 Stock Option Plan
Certain executives and key employees of the Company were granted stock options under TD Group’s 2003 stock option plan. Upon the closing of the acquisition of the Company by Warburg Pincus in 2003, certain employees rolled over certain then-existing options to purchase shares of common stock of TransDigm Holdings. These employees were granted rollover options to purchase an aggregate of 3,870,152 shares of common stock of TD Group (after giving effect to the 149.60 for 1.00 stock split effected on March 14, 2006). All rollover options granted were fully vested on the date of grant. In addition to shares of common stock reserved for issuance upon the exercise of rollover options, an aggregate of 5,469,301 shares of TD Group’s common stock were reserved for issuance upon the exercise of new management options. In general, approximately 20% of all new management options vested based on employment service or a change in control. These time vested options had a graded vesting schedule of up to four years. Approximately 80% of all new management options vested (i) based upon the satisfaction of specified performance criteria, which is annual and cumulative EBITDA As Defined targets through 2008, or (ii) upon the occurrence of a change in control if the Investor Group (defined as Warburg Pincus and the other initial investors in TD Group) received a minimum specified rate of return. Unless terminated earlier, the options expire ten years from the date of grant.
TD Group reserved a total of 9,339,453 shares of its common stock for issuance to the Company’s employees under the plan, which had all been issued as of September 30, 2013.

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

The carrying amount of the debt instrument is presented net of the debt issuance costs.
The Company values its financial instruments using an industry standard market approach, in which prices and other relevant information is generated by market transactions involving identical or comparable assets or liabilities. No financial instruments were recognized using unobservable inputs.
Interest rate swaps were measured at fair value using quoted market prices for the swap interest rate indexes over the term of the swap discounted to present value versus the fixed rate of the contract. The interest rate caps were measured at fair value using implied volatility rates of each individual caplet and the yield curve for the related periods. The estimated fair value of the Company’s term loans was based on information provided by the agent under the Company’s senior secured credit facility. The estimated fair values of the Company’s notes were based upon quoted market prices. There has not been any impact to the fair value of derivative liabilities due to the Company’s own credit risk. Similarly, there has not been any impact to the fair value of derivative assets based on the Company’s evaluation of counterparties’ credit risks.
The fair value of cash and cash equivalents, trade accounts receivable-net and accounts payable approximated book value due to the short-term nature of these instruments at September 30, 2017 and 2016.

20.    DERIVATIVES AND HEDGING ACTIVITIES
The Company is exposed to, among other things, the impact of changes in interest rates in the normal course of business. The Company’s risk management program is designed to manage the exposure and volatility arising from these risks, and utilizes derivative financial instruments to offset a portion of these risks. The Company uses derivative financial instruments only to the extent necessary to hedge identified business risks and does not enter into such transactions for trading purposes. The Company generally does not require collateral or other security with counterparties to these financial instruments and is therefore subject to credit risk in the event of nonperformance; however, the Company monitors credit risk and currently does not anticipate nonperformance by other parties. The Company has agreements with each of its swap and cap counterparties that contain a provision whereby if the Company defaults on the credit facility the Company could also be declared in default on its swaps and caps, resulting in an acceleration of payment under the swaps and caps.
Interest rate swap and cap agreements are used to manage interest rate risk associated with floating-rate borrowings under our credit facility. The interest rate swap and cap agreements utilized by the Company effectively modify the Company’s exposure to interest rate risk by converting a portion of the Company’s floating-rate debt to a fixed rate basis through the expiration date of the interest rate swap and cap agreements, thereby reducing the impact of interest rate changes on future interest expense. These agreements involve the receipt of floating rate amounts in exchange for fixed rate interest payments over the term of the agreements without an exchange of the underlying principal amount. These derivative instruments qualify as effective cash flow hedges under GAAP. For these cash flow hedges, the effective portion of the gain or loss from the financial instruments was initially reported as a component of accumulated other comprehensive loss in stockholders’ deficit and subsequently reclassified into earnings in the same line as the hedged item in the same period or periods during which the hedged item affected earnings.

All interest rate swap and cap agreements are recognized in our consolidated balance sheets at fair value. In accordance with GAAP, certain derivative asset and liability balances are offset where master netting agreements provide for the legal right of setoff. For classification purposes, we record the net fair value of each type of derivative position that is expected to settle in less than one year with each counterparty as a net current asset or liability and each type of long-term position as a net long-term asset or liability. The amounts shown in the table below represent the gross amounts of recognized assets and liabilities, the amounts offset in the consolidated balance sheet and the net amounts of assets and liabilities presented therein.

Refer to Note 19, "Fair Value Measurements," for the consolidated balance sheet classification of our interest rate swap and cap agreements.
In connection with the refinancing of the 2011 Term Loans, the Company no longer designated the interest rate swap agreements relating to the $353 million aggregate notional amount as cash flow hedges for accounting purposes. Accordingly, amounts previously recorded as a component of accumulated other comprehensive loss in stockholder’s deficit amortized into earnings totaled $3.2 million for the fiscal year ended September 30, 2015. There was no remaining amortization for these dedesignated swap agreements as of September 30, 2015.
Based on the fair value amounts of the interest rate swap and cap agreements determined as of September 30, 2017, the estimated net amount of existing gains and losses and caplet amortization expected to be reclassified into interest expense within the next twelve months is approximately $24.9 million.
Effective September 30, 2016, the Company redesignated the interest rate cap agreements related to the $400 million and the $750 million aggregate notional amount with cap rates of 2.0% and 2.5%, respectively, based on the expected probable cash flows associated with the 2016 term loans and 2015 term loans in consideration of the Company’s ability to select one-month, two-month, three-month, or six-month LIBO rate set forth in the Credit Agreement.  Accordingly, amounts previously recorded as a component of accumulated other comprehensive loss in stockholder’s deficit amortized into interest expense was $3.8 million for the fiscal year ended September 30, 2017. The accumulated other comprehensive loss to be reclassified into interest expense over the remaining term of the cap agreements is $10.8 million with a related tax benefit of $4.0 million as of September 30, 2017. The amount recorded as a component of accumulated other comprehensive loss in stockholders’ deficit related to these redesignated interest rate cap hedges as of September 30, 2016 was approximately $14.6 million with a related tax benefit of $5.5 million.

22.    DISCONTINUED OPERATIONS
In connection with the settlement of a Department of Justice investigation into the competitive effects of the acquisition, during the fourth quarter of 2017, the Company committed to dispose of the Schroth business.  Therefore, Schroth was classified as held-for-sale as of September 30, 2017. The results of operations of Schroth are reflected as discontinued operations in the accompanying consolidated financial statements for all periods presented. The Company previously acquired Schroth in February 2017 (refer to Note 2, “Acquisitions”). Schroth designs and manufactures proprietary, highly engineered, advanced safety systems for aviation, racing and military ground vehicles around the world.
The loss from discontinued operations in the consolidated statements of income includes a $32.0 million impairment charge to write down the Schroth assets to fair value. The impairment charge recorded in the fourth quarter of 2017 was based on an internal assessment of the recovery of Schroth’s assets.  Schroth’s assets have been recorded at fair value in the consolidated balance sheets as of September 30, 2017. The following is the summarized operating results from the date of acquisition of February 22, 2017 to September 30, 2017 (in thousands):
