General
Triumph Group, Inc. ("Triumph", the "Company", "we", "us", or "our") was incorporated in 1993 in Delaware. Our companies design, engineer, manufacture, repair, overhaul and distribute a broad portfolio of aerostructures, aircraft components, accessories, subassemblies and systems. We serve a broad, worldwide spectrum of the aviation industry, including original equipment manufacturers, or OEMs, of commercial, regional, business and military aircraft and aircraft components, as well as commercial and regional airlines and air cargo carriers.

Products and Services
Effective January 1, 2018, the Company combined its Aerospace Structures and Precision Components reporting segments into one reporting segment, Aerospace Structures. Aerospace Structures and Precision Components share many of the same customers and suppliers and have substantial inter-company work on common programs. As a single operating segment, the Company believes it will be able to leverage its combined resources to make it more cost competitive and to enhance performance. The newly formed operating segment is also a reportable segment. As a result, effective January 1, 2018, the Company has three reporting segments for financial reporting purposes - Integrated Systems, Aerospace Structures, and Product Support.
We offer a variety of products and services to the aerospace industry through three operating segments: (i) Triumph Aerostructures Group,Integrated Systems, whose companies'companies revenues are derived from the design, manufacture, assemblydevelopment and integrationsupport of proprietary components, subsystems and systems, as well as production of complex assemblies using external designs; (ii) Triumph Aerospace Structures, whose companies supply commercial, business, regional and military manufacturers with large metallic and composite aerostructuresstructures and structural components for the global aerospace OEM market; (ii) Triumph Aerospace Systems Group, whose companies design, engineerproduce close-tolerance parts primarily to customer designs and manufacturemodel-based definition, including a wide range of proprietaryaluminum, hard metal and build-to-print components, assemblies and systems also for the OEM market;composite structure capabilities; and (iii) Triumph Aftermarket Services Group,Product Support, whose companies serve aircraft fleets, notablyprovide full life cycle solutions for commercial, airlines, the U.S.regional and military and cargo carriers, through the maintenance, repair and overhaul of aircraft components and accessories manufactured by third parties.aircraft.

Certain financial information about our three segments is set forth in Note 212 of "Notes to Consolidated Financial Statements."
Effective April 2016, the Company announced that it is realigning into four business units to better meet the evolving needs of its customers. The new structure better supports our go-to-market strategies and will allow us to more effectively satisfy the needs of our customers while continuing to deliver on our commitments, accelerate organic growth and drive predictable profitability. During the first quarter of fiscal 2017, our segment financial performance information will be presented in accordance with these new four business units.
The four business units are as follows:
Integrated Systems. Provides integrated solutions including design, development and support of proprietary components, subsystems and systems, as well as production of complex assemblies using external designs.  Capabilities include hydraulic, mechanical and electro-mechanical actuation, power and control; a complete suite of aerospace gearbox solutions including engine accessory gearboxes and helicopter transmissions; active and passive heat exchange technology; fuel pumps, fuel metering units and Full Authority Digital Electronic Control fuel systems; hydro-mechanical and electromechanical primary and secondary flight controls; and a broad spectrum of surface treatment options.

Aerospace Structures. Supplies commercial, business, regional and military manufacturers with large metallic and composite structures. Products include wings, wing boxes, fuselage panels, horizontal and vertical tails and sub-assemblies such as floor grids. Inclusive of the former Vought Aircraft Division, Aerospace Structures also has the capability to engineer detailed structural designs in metal and composites.
Precision Components. Produces close-tolerance parts primarily to customer designs and model-based definition, including a wide range of aluminum, hard metal and composite structure capabilities. Capabilities include complex machining, gear manufacturing, sheet metal fabrication, forming, advanced composite and interior structures, joining processes such as welding, autoclave bonding and conventional mechanical fasteners and a variety of special processes including: super plastic titanium forming, aluminum and titanium chemical milling and surface treatments.
Product Support. Provides full life cycle solutions for commercial, regional and militaryaircraft.Triumph’s extensive product and service offerings include full post-delivery value chain services that simplify the MRO supply chain. Through its line maintenance, component MRO and postproduction supply chain activities, Triumph’s Product Support group is positioned to provide integrated planeside repair solutions globally. Capabilities include fuel tank repair, metallic and composite aircraft structures, nacelles, thrust reversers, interiors, auxiliary power units and a wide variety of pneumatic, hydraulic, fuel and mechanical accessories.
Proprietary Rights
We benefit from our proprietary rights relating to designs, engineering and manufacturing processes, and repair and overhaul procedures. For some products, our unique manufacturing capabilities are required by the customer's specifications or designs, thereby necessitating reliance on us for the production of such specially designed products.
We view our name and mark, as well as the Vought and Embee tradenames,trademark as significant to our business as a whole. Our products are protected by a portfolio of patents, trademarks, licenses or other forms of intellectual property that expire at various dates in the future. We continually develop and acquire new intellectual property and consider all of our intellectual property to be valuable. However, based on the broad scope of our product lines, management believes that the loss or expiration of any single intellectual property right would not have a material adverse effect on our results of operations, our financial position or our business segments. Our policy is to file applications and obtain patents for our new products as appropriate, including product modifications and improvements. While patents generally expire 20 years after the patent application filing date, new patents are issued to us on a regular basis.
In our overhaul and repair businesses, OEMs of equipment that we maintain for our customers often include language in repair manuals that relate to their equipment, asserting broad claims of proprietary rights to the contents of the manuals used in our operations. There can be no assurance that OEMs will not try to enforce such claims, including the possible use of legal proceedings. In the event of such legal proceedings, there can be no assurance that such actions against the Company will be unsuccessful. However, we believe that our use of manufacture and repair manuals is lawful.
Raw Materials and Replacement Parts
We purchase raw materials, primarily consisting of extrusions, forgings, castings, aluminum and titanium sheets and shapes and stainless steel alloys, from various vendors. We also purchase replacement parts, which are utilized in our various repair and overhaul operations. We believe that the availability of raw materials to us is adequate to support our operations.
Sales, Marketing and Engineering
While each of our operating companies maintains responsibility for selling and marketing its specific products, we have developed two marketing teams at the group level who are focused on cross-selling our broad capabilities. One team supports the AerostructuresIntegrated Systems and Aerospace Systems GroupsStructures and the other the Aftermarket Services Group.team supports Product Support. These teams are responsible for selling systems, integrated assemblies and repair and overhaul services, reaching across our operating companies, to our OEM, military, airline and air cargo customers. In certain limited cases, we use independent, commission-based representatives to serve our customers' changing needs and the current trends in some of the markets and geographic regions in which we operate.
The two group-level marketing teams operate as the front-end of the selling process, establishing or maintaining relationships, identifying opportunities to leverage our brand, and providing service for our customers. Each individual operating company is responsible for its own technical support, pricing, manufacturing and product support. Also, within the Aerospace Systems Group,Product Support, we have created a group engineering function to provide integrated solutions to meet our customer needs by designing systems that integrate the capabilities of our companies.

Also, we are increasingly meeting our customers' needs by designing systems that integrate the extended capabilities of our companies.
A significant portion of our government and defense contracts are awarded on a competitive bidding basis. We generally do not bid or act as the primary contractor, but will typically bid and act as a subcontractor on contracts on a fixed-price basis. We generally sell to our other customers on a fixed-price, negotiated contract or purchase order basis.
Backlog
We have a number of long-term agreements with several of our customers. These agreements generally describe the terms under which the customer may issue purchase orders to buy our products and services during the term of the agreement. These terms typically include a list of the products or repair services customers may purchase, initial pricing, anticipated quantities and, to the extent known, delivery dates. In tracking and reporting our backlog, however, we only include amounts for which we have actual purchase orders with firm delivery dates or contract requirements generally within the next 24 months, which primarily relate to sales to our OEM customer base. Purchase orders issued by our aftermarket customers are usually completed within a short period of time. As a result, our backlog data relates primarily to the OEM customers. The backlog information set forth below does not include the sales that we expect to generate from long-term agreements for which we do not have actual purchase orders with firm delivery dates.

As of March 31, 20162018, we had outstanding purchase orders representing an aggregate invoice price of approximately $4.154.50 billion, of which $2.96$1.34 billion, $1.15$3.13 billion and $3727 million relate to the Aerostructures Group, theIntegrated Systems, Aerospace Systems GroupStructures and the Aftermarket Services Group,Product Support, respectively. As of March 31, 20152017, our continuing operations had outstanding purchase orders representing an aggregate invoice price of approximately $5.03$3.98 billion, of which $3.74$1.08 billion, $1.24$2.86 billion and $4233 million related to the Aerostructures Group, theIntegrated Systems, Aerospace Systems GroupStructures and the Aftermarket Services Group,Product Support, respectively. The sharp decline in backlog was due to the production rate reductions on key programs such as Boeing 747-8, 777 and G450/G550. Of the existing backlog of $4.15$4.50 billion, approximately $1.50$1.85 billion will not be shipped by March 31, 2017.2019.
Dependence on Significant Customers
For the fiscal years ended March 31, 2016, 20152018, 2017 and 20142016, the Boeing Company ("Boeing") represented approximately 38%31%, 42%35% and 45%38%, respectively, of our net sales, covering virtually every Boeing plant and product.
For the fiscal years ended March 31, 2016, 20152018, 2017 and 20142016, Gulfstream Aerospace Corporation ("Gulfstream") represented approximately 12%13%, 9%12% and 8%12%, respectively, of our net sales, covering several of Gulfstream's products.
A significant reduction in sales to Boeing and/or Gulfstream would have a material adverse impact on our financial position, results of operations and cash flows.
United States and International Operations
Our revenues from customers in the United States for the fiscal years ended March 31, 2016, 20152018, 2017 and 20142016 ,were, were approximately $3,0882,440 million, $3,1362,764 million, and $3,1423,088 million, respectively. Our revenues from customers in all other countries for the fiscal years ended March 31, 2016, 20152018, 2017 and 20142016, were approximately $798759 million, $753769 million, and $622798 million, respectively.
As of March 31, 20162018 and 20152017, our long-lived assets located in the United States were approximately $2,7461,661 million and $3,6832,326 million, respectively. As of March 31, 20162018 and 20152017, our long-lived assets located in all other countries were approximately $347223 million and $367315 million, respectively.
Competition
We compete primarily with Tier 1 and Tier 2 aerostructures manufacturers, systems suppliers and component manufacturers, some of which are divisions or subsidiaries of other large companies, in the manufacture of aircraft structures, systems components, subassemblies and detail parts. OEMs are increasingly focusing on assembly and integration activities while outsourcing more manufacturing and, therefore, are less of a competitive force than in previous years.
Competition for the repair and overhaul of aviation components comes from four primary sources, some of whom possess greater financial and other resources than we have: OEMs, major commercial airlines, government support depots, and other independent repair and overhaul companies. Some major commercial airlines continue to own and operate their own service centers, while others have begun to sell or outsource their repair and overhaul services to other aircraft operators or third parties. Large domestic and foreign airlines that provide repair and overhaul services typically provide these services not only for their own aircraft but for other airlines as well. OEMs also maintain service centers which provide repair and overhaul services for the components they manufacture. Many governments maintain aircraft support depots in their military organizations that maintain and repair the aircraft they operate. Other independent service organizations also compete for the repair and overhaul business of other users of aircraft components.

Participants in the aerospace industry compete primarily on the basis of breadth of technical capabilities, quality, turnaround time, capacity and price.
Government Regulation and Industry Oversight
The aerospace industry is highly regulated in the United States by the FAA and in other countries by similar agencies. We must be certified by the FAA and, in some cases, by individual OEMs, in order to engineer and service parts and components used in specific aircraft models. If material authorizations or approvals were revoked or suspended, our operations would be adversely affected. New and more stringent government regulations may be adopted, or industry oversight heightened, in the future and these new regulations, if enacted, or any industry oversight, if heightened, may have an adverse impact on us.
We must also satisfy the requirements of our customers, including OEMs, that are subject to FAA regulations, and provide these customers with products and repair services that comply with the government regulations applicable to aircraft components used in commercial flight operations. The FAA regulates commercial flight operations and requires that aircraft components meet its stringent standards. In addition, the FAA requires that various maintenance routines be performed on aircraft components, and we currently satisfy these maintenance standards in our repair and overhaul services. Several of our operating locations are FAA-approved repair stations.
Generally, the FAA only grants licenses for the manufacture or repair of a specific aircraft component, rather than the broader licenses that have been granted in the past. The FAA licensing process may be costly and time-consuming. In order to

obtain an FAA license, an applicant must satisfy all applicable regulations of the FAA governing repair stations. These regulations require that an applicant have experienced personnel, inspection systems, suitable facilities and equipment. In addition, the applicant must demonstrate a need for the license. Because an applicant must procure manufacturing and repair manuals from third parties relating to each particular aircraft component in order to obtain a license with respect to that component, the application process may involve substantial cost.
The license approval processes for the European Aviation Safety Agency ("EASA"), which regulates this industry in the European Union,Union; the Civil Aviation Administration of China,China; and other comparable foreign regulatory authorities are similarly stringent, involving potentially lengthy audits. EASA was formed in 2002 and is handling most of the responsibilities of the national aviation authorities in Europe, such as the United Kingdom Civil Aviation Authority.
Our operations are also subject to a variety of worker and community safety laws. For example, the Occupational Safety and Health Act of 1970, or OSHA, mandates general requirements for safe workplaces for all employees in the United States. In addition, OSHA provides special procedures and measures for the handling of hazardous and toxic substances. Specific safety standards have been promulgated for workplaces engaged in the treatment, disposal or storage of hazardous waste. We believe that our operations are in material compliance with OSHA's health and safety requirements.
Environmental Matters
Our business, operations and facilities are subject to numerous stringent federal, state, local and foreign environmental laws and regulation by government agencies, including the Environmental Protection Agency ("EPA"). Among other matters, these regulatory authorities impose requirements that regulate the emission, discharge, generation, management, transportation and disposal of hazardous materials, pollutants and contaminants, govern public and private response actions to hazardous or regulated substances which may be or have been released to the environment, and require us to obtain and maintain licenses and permits in connection with our operations. This extensive regulatory framework imposes significant compliance burdens and risks on us. Although management believes that our operations and our facilities are in material compliance with such laws and regulations, future changes in these laws, regulations or interpretations thereof or the nature of our operations or regulatory enforcement actions which may arise, may require us to make significant additional capital expenditures to ensure compliance in the future.
Certain of our facilities, including facilities acquired and operated by us or one of our subsidiaries have at one time or another been under active investigation for environmental contamination by federal or state agencies when acquired, and at least in some cases, continue to be under investigation or subject to remediation for potential environmental contamination. We are frequently indemnified by prior owners or operators and/or present owners of the facilities for liabilities which we incur as a result of these investigations and the environmental contamination found which pre-dates our acquisition of these facilities, subject to certain limitations. We also maintain a pollution liability policy that provides coverage for certain material liabilities associated with the clean-up of on-site pollution conditions, as well as defense and indemnity for certain third-party suits (including Superfund liabilities at third-party sites), in each case, to the extent not otherwise indemnified. This policy applies to all of our manufacturing and assembly operations worldwide. Also, as we proceed with our plans to exit certain facilities as part of restructuring and related initiatives, the need for remediation for potential environmental contamination could be

identified. If we are required to pay the expenses related to environmental liabilities because neither indemnification nor insurance coverage is available, these expenses could have a material adverse effect on us.
Employees
As of March 31, 20162018, we employed 14,60213,554 persons, of whom 3,4653,446 were management employees, 12593 were sales and marketing personnel, 782747 were technical personnel, 889607 were administrative personnel and 9,3418,661 were production workers. Our segments were composed of the following employees: Aerostructures GroupIntegrated Systems - 9,5952,803 persons, Aerospace Systems GroupStructures - 3,5679,515 persons, Aftermarket Services GroupProduct Support - 1,3111,062 persons, and Corporate - 129174 persons.
Several of our subsidiaries are parties to collective bargaining agreements with labor unions. Under those agreements, we currently employ approximately 1,9072,293 full-time employees. Currently, approximately 13%17% of our permanent employees are represented by labor unions and approximately 51%49% of net sales are derived from the facilities at which at least some employees are unionized. The collective bargaining agreement with our union employees with International Association of Machinists and Aerospace Workers ("IAM") District 751 at our Spokane, Washington facility has expired. As of May 11, 2016, the workforce in Spokane of approximately 400 employees has elected to strike. While we are currently in negotiations with the workforce, we have implemented plans to continue production in Spokane with support from other locations. Of the 1,9072,293 employees represented by unions, 591no employees are working under contracts that have expired or will expire within one year.
During the fiscal year ended March 31, 2017, we settled a strike and 475agreed to a new collective bargaining agreement with our union employees with IAM District 751 at our Spokane, Washington facility which had expired during the quarter, resulting in oura charge of $15.7 million due to disruption costs.

During the fiscal year ended March 31, 2018, the Company ratified a collective bargaining agreement with its union employees with United Autoworkers of America and its Local Union 848 at its Red Oak, Texas facility.
Subsequent to the fiscal year ended March 31, 2018, the Company ratified a collective bargaining agreement with its union employees with United Autoworkers of America and 386 employees in ourits Local Union 952 at its Tulsa, Oklahoma facilities have not yet negotiated initial contracts. facility.
Our inability to negotiate an acceptable contract with any of these labor unions could result in strikes by the affected workers and increased operating costs as a result of higher wages or benefits paid to union members. If the unionized workers were to engage in a strike or other work stoppage, or other employees were to become unionized, we could experience a significant disruption of our operations and higher ongoing labor costs, which could have an adverse effect on our business and results of operations.
Research and Development Expenses
Certain information about our research and development expenses for the fiscal years ended March 31, 2016, 20152018, 2017 and 20142016, is available in Note 2 of "Notes to Consolidated Financial Statements."

Item 1A.Risk Factors
Factors that have an adverse impact on the aerospace industry may adversely affect our results of operations and liquidity.
A substantial percentage of our gross profit and operating income derives from commercial aviation. Our operations have been focused on designing, engineering, manufacturing, repairing and overhauling a broad portfolio of aerostructures, aircraft components, accessories, subassemblies and systems. Therefore, our business is directly affected by economic factors and other trends that affect our customers in the aerospace industry, including a possible decrease in outsourcing by OEMs and aircraft operators or projected market growth that may not materialize or be sustainable. We are also significantly dependent on sales to the commercial aerospace market, which has been cyclical in nature with significant downturns in the past. When these economic and other factors adversely affect the aerospace industry, they tend to reduce the overall customer demand for our products and services, which decreases our operating income. Economic and other factors that might affect the aerospace industry may have an adverse impact on our results of operations and liquidity. We have credit exposure to a number of

commercial airlines, some of which have encountered financial difficulties. In addition, an increase in energy costs and the price of fuel to the airlines could result in additional pressure on the operating costs of airlines. The market for jet fuel is inherently volatile and is subject to, among other things, changes in government policy on jet fuel production, fluctuations in the global supply of crude oil and disruptions in oil production or delivery caused by hostility in oil-producing areas. Airlines are sometimes unable to pass on increases in fuel prices to customers by increasing fares due to the competitive nature of the airline industry, and this compounds the pressure on operating costs. Other events of general impact such as natural disasters, war, terrorist attacks against the industry or pandemic health crises may lead to declines in the worldwide aerospace industry that could adversely affect our business and financial condition.
In addition, demand for our maintenance, repair and overhaul services is strongly correlated with worldwide flying activity. A significant portion of the MRO activity required on commercial aircraft is mandated by government regulations that limit the total time or number of flights that may elapse between scheduled MRO events. As a result, although short-term deferrals are possible, MRO activity is ultimately required to continue to operate the aircraft in revenue-producing service. Therefore, over the intermediate and long-term, trends in the MRO market are closely related to the size and utilization level of the worldwide aircraft fleet, as reflected by the number of available seat miles, commonly referred to as ASMs, and cargo miles flown. Consequently, conditions or events which contribute to declines in worldwide ASMs and cargo miles flown, such as those mentioned above, could negatively impact our MRO business.

We may not be successful in achieving expected operating efficiencies and sustaining or improving operating expense reductions, and may experience business disruptions associated with restructuring, facility consolidations, realignment, cost reduction and other strategic initiatives.
Over the past several years we have implemented a number of restructuring, realignment and cost reduction initiatives, including facility consolidations, organizational realignments and reductions in our workforce. While we have realized some efficiencies from these actions, we may not realize the benefits of these initiatives to the extent we anticipated. Further, such benefits may be realized later than expected, and the ongoing difficulties in implementing these measures may be greater than anticipated, which could cause us to incur additional costs or result in business disruptions. In addition, if these measures are not successful or sustainable, we may be compelled to undertake additional realignment and cost reduction efforts, which could result in significant additional charges. Moreover, if our restructuring and realignment efforts prove ineffective, our ability to achieve our other strategic and business plan goals may be adversely affected.
Changes in levels of U.S. Governmentgovernment defense spending or overall acquisition priorities could negatively impact our financial position and results of operations.
We derive a substantialsignificant portion of our revenue from the U.S. Government,government, primarily from defense related programs with the U.S. Department of Defense ("DoD") .DoD. Levels of U.S. defense spending in future periods are very difficult to predict and subjectmay be impacted by numerous factors such as the political environment, U.S. foreign policy, macroeconomic conditions and the ability of the U.S. government to significant risks. enact relevant legislation such as authorization and appropriations bills.
In addition, significant budgetary delays and constraints have already resulted in reduced spending levels, and additional reductions may be forthcoming. In August 2011, theThe Budget Control Act (the "Act")of 2011 established limits on U.S. Governmentgovernment discretionary spending, including a reduction of defense spending by approximately $490 billion between the 2012 and 2021 U.S. Governmentgovernment fiscal years. The Act also provided that the defense budget would face “sequestration” cuts of up to an additional $500 billion during that same period to the extent that discretionary spending limits are exceeded. The impact of sequestration cuts has been reduced with respect to FY2016 and FY2017 following the enactment of The Bipartisan Budget Act of 2015 in November 2015. However,Accordingly, long-term uncertainty remains with respect to overall levels of defense spending and it is likely that U.S. Governmentgovernment discretionary spending levels will continue to be subject to significant pressure, including risk of future sequestration cuts.pressure.
In addition, there continues to be significant uncertainty with respect to program-level appropriations for the U.S. DoD and other government agencies (including NASA) within the overall budgetary framework described above. While the FY2016 appropriations enacted December 2015House and Senate Appropriations committees included funding for Boeing’s major military programs in fiscal year 2018, such as F/A-18, CH-47 Chinook, AH-64 Apache, KC-46A Tanker, UH-60 Black Hawk, Northrop Grumman Global Hawk and P-8V-22 Osprey programs, uncertainty remains about how defense budgets in FY2017fiscal year 2019 and beyond will affect Boeing’sthese programs. We also expect that ongoing concerns regarding the U.S. national debt will continue to place downward pressure on DoD spending levels. Future budget cuts, including cuts mandated by sequestration, or future procurement decisions associated with the authorizations and appropriations process could result in reductions, cancellations, and/or delays of existing contracts or programs. Any of these impacts could have a material effect on the results of the Company’s operations, financial position and/or cash flows.
In addition, as a result of the significant ongoing uncertainty with respect to both U.S. defense spending levels and the nature of the threat environment, we expect the U.S. DoD to continue to emphasize cost-cutting and other efficiency initiatives in its

procurement processes. If we can no longer adjust successfully to these changing acquisition priorities and/or fail to meet affordability targets set by the U.S. DoD customer, our revenues and market share would be further impacted.
Cancellations, reductionsOur business could be negatively affected by cyber or delays in customer orders may adversely affect our results of operations.other security threats or other disruptions.
Our overall operating results are affected by many factors,businesses depend heavily on information technology and computerized systems to communicate and operate effectively. The Company's systems and technologies, or those of third parties on which we rely, could fail or become unreliable due to equipment failures, software viruses, cyber threats, terrorist acts, natural disasters, power failures or other causes. These threats arise in some cases as a result of our role as a defense contractor. Our customers, including the timing of orders from large customersU.S. government, are increasingly requiring cybersecurity protections and the timing of expenditures to manufacture parts and purchase inventorymandating cybersecurity standards in anticipation of future sales ofour products and services. A large portionwe may incur additional cost to comply with such demands.
Cybersecurity threats are evolving and include, but are not limited to, malicious software; attempts to gain unauthorized access to our sensitive information, including that of our operating expenses are relatively fixed. Because severalcustomers, suppliers, subcontractors, and joint venture partners; and other electronic security breaches that could lead to disruptions in mission critical systems, unauthorized release of our operating locations typically doconfidential or otherwise protected information and corruption of data.
Although we utilize various procedures and controls to monitor and mitigate these threats, there can be no assurance that these procedures and controls will be sufficient to prevent security threats from materializing. If any of these events were to materialize, the costs related to cyber or other security threats or disruptions may not obtain long-term purchase ordersbe fully insured or commitments from our customers, they must anticipate the future volume of orders based upon the historic purchasing patterns of customersindemnified and upon our discussions with customers as to their anticipated future requirements. These historic patterns may be disrupted by many factors, including changing economic conditions, inventory adjustments, or work stoppages or labor disruptions at our customers' locations. Cancellations, reductions or delays in orders by a customer or group of customers could have a material adverse effect on our business,reputation, operating results and financial condition and results of operations.condition.

Our acquisition strategy exposes us to risks, including the risk that we may not be able to successfully integrate acquired businesses.
We have a consistent strategy to grow, in part, through the acquisition of additional businesses in the aerospace industry and are continuously evaluating various acquisition opportunities, including those outside the United States and those that may have a material impact on our business. Our ability to grow by acquisition is dependent upon, among other factors, the availability of suitable acquisition candidates. Growth by acquisition involves risks thatsubstantial debt could adversely affect our financial condition and our ability to operate and grow our business. The terms of our indentures governing our Senior Notes and Revolving Credit Facility impose significant operating results, including difficulties in integrating the operations and personnel of acquired companies, the risk of diverting the attention of senior managementfinancial restrictions on our company and our subsidiaries, which could also adversely affect our operating flexibility and put us at a competitive disadvantage by preventing us from our existing operations, the potential amortization of acquired intangible assets, the potential impairment of goodwillcapitalizing on business opportunities and the potential loss of key employees of acquired companies. Weadditional financing may not be available on terms acceptable to us.
The terms of our indentures governing our Senior Notes, Revolving Credit Facility and Securitization Facility (each as defined in Note 10 of the “Notes to the Consolidated Financial Statements”) impose significant operating and financial restrictions on us, which limit our ability to incur liens, sell assets and enter into certain transactions, among other things.  In addition, our debt instruments require us to maintain compliance with financial covenants.
We cannot assure you that we will be able to consummate acquisitions on satisfactory termsmaintain compliance with the covenants in the agreements governing our indebtedness in the future or, if any acquisitions are consummated, successfully integratewe fail to do so, that we will be able to obtain waivers from the lenders and /or amend the covenants. Failure to maintain compliance with these acquired businesses.
A significant decline in business with a key customercovenants could have a material adverse effect on us.our operations.
Boeing, We may periodically need to obtain additional financing in order to meet our debt obligations as they come due, to support our operations and/or Boeing Commercial, Militaryto make acquisitions. Our access to the debt capital markets and Space, represented approximately 38%the cost of borrowings are affected by a number of factors including market conditions and the strength of our net sales for the fiscal year ended March 31, 2016, covering virtually every Boeing plantcredit ratings. If we cannot obtain adequate sources of credit on favorable terms, or at all, our business, operating results, and product. Gulfstream represented approximately 12% of our net sales for the fiscal year ended March 31, 2016, covering several Gulfstream plants and products. As a result, a significant reduction in purchases by Boeing and/or Gulfstreamfinancial condition could have a material adverse impact on our financial position, results of operations, and cash flows. In addition, some of our other group companies rely significantly on particular customers, the loss of which could have an adverse effect on those businesses.be adversely affected.
The profitability of certain development programs depends significantly on the assumptions surrounding satisfactory settlement of claims and assertions.
For certain of our new development programs, we regularly commence work or incorporate customer-requested changes prior to negotiating pricing terms for engineering work or the product which has been modified. We typically have the legal right to negotiate pricing for customer-directed changes. In those cases, we assert to our customers our contractual rights to obtain the additional revenue or cost reimbursement we expect to receive upon finalizing pricing terms. An expected recovery value of these assertions is incorporated into our contract profitability estimates when applying contract accounting. Our inability to recover these expected values, among other factors, could result in the recognition of a forward loss on these programs or a lower than expected profit margin and could have a material adverse effect on our results of operations. In addition, negotiations over our claims may lead to disputes with our customers that would result in litigation and its associated costs and risks of damages, penalties and injunctive relief, any of which could have a material, adverse effect on our business and results of operations.
We incur risk associated with new programs.
New programs with new technologies typically carry risks associated with design responsibility, development of new production tools, hiring and training of qualified personnel, increased capital and funding commitments, ability to meet customer specifications, delivery schedules and unique contractual requirements, supplier performance, ability of the customer to meet its contractual obligations to us, and our ability to accurately estimate costs associated with such programs. In addition, any new aircraft program may not generate sufficient demand or may experience technological problems or significant delays in the regulatory certification or manufacturing and delivery schedule. If we were unable to perform our obligations under new programs to the customer's satisfaction or manufacture products at our estimated costs, if we were to experience unexpected fluctuations in raw material prices or supplier problems leading to cost overruns, if we were unable to successfully perform under revised design and manufacturing plans or successfully resolve claims and assertions, or if a new program in which we had made a significant investment was terminated or experienced weak demand, delays or technological problems, our business, financial condition and results of operations could be materially adversely affected. This risk includes the potential for

default, quality problems, or inability to meet weight requirements and could result in low margin or forward loss contracts, and the risk of having to write-off inventory if it were deemed to be unrecoverable over the life of the program. In addition, beginning new work on existing programs also carries risks associated with the transfer of technology, knowledge and tooling.
In order to perform on new programs we may be required to construct or acquire new facilities requiring additional up-front investment costs. In the case of significant program delays and/or program cancellations, we could be required to bear certain unrecoverable construction and maintenance costs and incur potential impairment charges for the new facilities. Also, we may need to expend additional resources to determine an alternate revenue generating use for the facilities. Likewise, significant delays in the construction or acquisition of a plant site could impact production schedules.

Future volatility in the financial markets may impede our ability to successfully access capital markets and ensure adequate liquidity and may adversely affect our customers and suppliers.
Future turmoil in the capital markets may impede our ability to access the capital markets when we would like, or need, to raise capital or may restrict our ability to borrow money on favorable terms. Such market conditions could have an adverse impact on our flexibility to react to changing economic and business conditions and on our ability to fund our operations and capital expenditures in the future. In addition, interest rate fluctuations, financial market volatility or credit market disruptions may also negatively affect our customers' and our suppliers' ability to obtain credit to finance their businesses on acceptable terms. As a result, our customers' need for and ability to purchase our products or services may decrease, and our suppliers may increase their prices, reduce their output or change their terms of sale. If our customers' or suppliers' operating and financial performance deteriorates, or if they are unable to make scheduled payments or obtain credit, our customers may not be able to pay, or may delay payment of, accounts receivable owed to us, and our suppliers may restrict credit or impose different payment terms. Any inability of customers to pay us for our products and services or any demands by suppliers for different payment terms may adversely affect our earnings and cash flow.
Cancellations, reductions or delays in customer orders may adversely affect our results of operations.
Our overall operating results are affected by many factors, including the timing of orders from large customers and the timing of expenditures to manufacture parts and purchase inventory in anticipation of future sales of products and services. A large portion of our operating expenses are relatively fixed. Because several of our operating locations typically do not obtain long-term purchase orders or commitments from our customers, they 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. These historic patterns may be disrupted by many factors, including changing economic conditions, inventory adjustments, or work stoppages or labor disruptions at our customers' locations. Cancellations, reductions or delays in orders by a customer or group of customers could have a material adverse effect on our business, financial condition and results of operations.
A significant decline in business with a key customer could have a material adverse effect on us.
Boeing, or Boeing Commercial, Military and Space, represented approximately 31% of our net sales for the fiscal year ended March 31, 2018, covering virtually every Boeing plant and product. Gulfstream represented approximately 13% of our net sales for the fiscal year ended March 31, 2018, covering several Gulfstream plants and products. As a result, a significant reduction in purchases by Boeing and/or Gulfstream could have a material adverse impact on our financial condition, results of operations, and cash flows. In addition, some of our individual companies rely significantly on particular customers, the loss of which could have an adverse effect on those businesses.
Our international sales and operations are subject to applicable laws relating to trade, export controls and foreign corrupt practices, the violation of which could adversely affect our operations.
We must comply with all applicable export control laws and regulations of the United States and other countries. United States laws and regulations applicable to us include the Arms Export Control Act, the International Traffic in Arms Regulations ("ITAR"), the Export Administration Regulations ("EAR") and the trade sanctions laws and regulations administered by the United States Department of the Treasury's Office of Foreign Assets Control ("OFAC"). EAR restricts the export of dual-use products and technical data to certain countries, while ITAR restricts the export of defense products, technical data and defense services. The U.S. Government agencies responsible for administering EAR and ITAR have significant discretion in the interpretation and enforcement of these regulations. We cannot provide services to certain countries subject to United States trade sanctions unless we first obtain the necessary authorizations from OFAC. In addition, we are subject to the Foreign Corrupt Practices Act which generally bars bribes or unreasonable gifts to foreign governments or officials.
Violations of these laws or regulations could result in significant additional sanctions, including fines, more onerous compliance requirements, more extensive debarments from export privileges, loss of authorizations needed to conduct aspects of our international business and criminal penalties and may harm our ability to enter into contracts with the U.S. Government. A future violation of ITAR or the other regulations enumerated above could materially adversely affect our business, financial condition and results of operations.
Any significant disruption from key suppliers of raw materials and key components could delay production and decrease revenue.
We are highly dependent on the availability of essential raw materials such as carbon fiber, aluminum and titanium, and purchased engineered component parts from our suppliers, many of which are available only from single customer-approved sources. Moreover, we are dependent upon the ability of our suppliers to provide raw materials and components that meet our

specifications, quality standards and delivery schedules. Our expansionsuppliers' failure to provide expected raw materials or component parts could require us to identify and enter into international markets may increase credit, currency and other risks,contracts with alternate suppliers that are acceptable to both us and our current operationscustomers, which could result in international markets expose ussignificant delays, expenses, increased costs and management distraction and adversely affect production schedules and contract profitability.
We have from time to such risks.time experienced limited interruptions of supply, and we may experience a significant interruption in the future. Our continued supply of raw materials and component parts are subject to a number of risks, including:
As we pursue customers in Asia, South America and other less developed aerospace markets throughout availability of capital to our suppliers;
the world, our inability to ensure the creditworthinessdestruction of our customers in these areas could adversely impactsuppliers' facilities or their distribution infrastructure;
a work stoppage or strike by our overall profitability. In addition,suppliers' employees;
the failure of our suppliers to provide raw materials or component parts of the requisite quality;
the failure of essential equipment at our suppliers' plants;
the failure or shortage of supply of raw materials to our suppliers;
contractual amendments and disputes with operations in Canada, China, France, Germany, Ireland, Mexico, Thailandour suppliers;
reduction to credit terms; and the United Kingdom, and customers throughout the world, we will be subject to the legal, political, social and regulatory requirements and economic conditions of other jurisdictions. In the future, we may also make additional international capital investments, including further acquisitions of companies outside the United States or companies having operations outside the United States. Risks inherent to international operations include, but are not limited to, the following:
difficulty in enforcing agreements in some legal systems outside the United States;
imposition of additional withholding taxes or other taxes on our foreign income, tariffs or other restrictions on foreign trade and investment, including currency exchange controls;
fluctuations in exchange rates which may affect demand for our products and services and may adversely affect our profitability in U.S. dollars;

inability to obtain, maintain or enforce intellectual property rights;
changes in general economic and politicalgeopolitical conditions in the countriesglobal supply base.
In addition, some contracts with our suppliers for raw materials, component parts and other goods are short-term contracts, which are subject to termination on a relatively short-term basis. The prices of our raw materials and component parts fluctuate depending on market conditions, and substantial increases in prices could increase our operating costs, which, we operate;
unexpected adverse changes in the laws or regulatory requirements outside the United States, including those with respect to environmental protection, export duties and quotas;
failure byas a result of our employees or agents to comply with U.S. laws affecting the activities of U.S. companies abroad;
difficulty with staffing and managing widespread operations; and
difficulty of and costs relating to compliance with the different commercial and legal requirements of the countries in whichfixed-price contracts, we operate.
We may need additional financing for internal growth and acquisitions and capital expenditures and additional financing may not be available on terms acceptableable to us.
A key elementrecoup through increases in the prices of our strategy has been, and continuesproducts.
Due to be, internal growth supplemented by growth through the acquisition of additional aerospace companies and product lines. In order to grow internally,economic difficulty, we may needface pressure to make significant capital expenditures, such as investingrenegotiate agreements resulting in facilities in low-cost countries, andlower margins. Our suppliers may need additional capitaldiscontinue provision of products to do so. Our ability to grow is dependent upon, and may be limited by, among other things, access to markets and conditions of markets, availability under the Credit Facility and the Securitization Facility (each as defined in Note 10 of the "Notes to Consolidated Financial Statements") and by particular restrictions contained in the Credit Facility and our other financing arrangements. In that case, additional funding sources may be needed,us at attractive prices or at all, and we may not be able to obtain such products in the additional capital necessary to pursue our internal growthfuture from these or other providers on the scale and acquisition strategywithin the time periods we require. Furthermore, substitute raw materials or if we can obtain additional financing, the additional financingcomponent parts may not meet the strict specifications and quality standards we and our customers demand, or that the U.S. Government requires. If we are not able to obtain key products on a timely basis and at an affordable cost, or we experience significant delays or interruptions of their supply, revenues from sales of products that use these supplies will decrease.
Significant consolidation by aerospace industry suppliers could adversely affect our business.
The aerospace industry continues to experience consolidation among suppliers and customers, primarily the airlines. Suppliers have consolidated and formed alliances to broaden their product and integrated system offerings and achieve critical mass. This supplier consolidation is in part attributable to aircraft manufacturers more frequently awarding long-term sole-source or preferred supplier contracts to the most capable suppliers, thus reducing the total number of suppliers. This consolidation could cause us to compete against certain competitors with greater financial resources, market penetration and purchasing power. When we purchase component parts and services from suppliers to manufacture our products, consolidation reduces price competition between our suppliers, which could diminish incentives for our suppliers to reduce prices. If this consolidation continues, our operating costs could increase and it may become more difficult for us to be on financial terms that are satisfactory to us.successful in obtaining new customers.
Competitive pressures may adversely affect us.
We have numerous competitors in the aerospace industry. We compete primarily with the top-tier systems integrators and the manufacturers that supply them, some of which are divisions or subsidiaries of OEMs and other large companies that manufacture aircraft components and subassemblies. Our OEM competitors, which include Boeing, Airbus, Bell Helicopter, Bombardier, Cessna, General Electric, Gulfstream, Honeywell, Lockheed Martin, Northrop Grumman, Raytheon, Rolls Royce and Sikorsky, may choose not to outsource production of aerostructures or other components due to, among other things, their own direct labor and overhead considerations, capacity utilization at their own facilities and desire to retain critical or core skills. Consequently, traditional factors affecting competition, such as price and quality of service, may not be significant determinants when OEMs decide whether to produce a part in-house or to outsource. We also face competition from non-OEM component manufacturers, including Alenia Aeronautica, Fokker Technologies, Fuji Heavy Industries, GKN Westland Aerospace (U.K.), Kawasaki Heavy Industries, Mitsubishi Heavy Industries, Spirit AeroSystems and UTC Aerospace Systems. Competition for the repair and overhaul of aviation components comes from three primary sources: OEMs, major commercial airlines and other independent repair and overhaul companies.

We may need to expend significant capital to keep pace with technological developments in our industry.
The aerospace industry is constantly undergoing development and change and it is likely that new products, equipment and methods of repair and overhaul service will be introduced in the future. In order to keep pace with any new developments, such as additive technology, we may need to expend significant capital to purchase new equipment and machines or to train our employees in the new methods of production and service.
The construction of aircraft is heavily regulated and failure to comply with applicable laws could reduce our sales or require us to incur additional costs to achieve compliance, and we may incur significant expenses to comply with new or more stringent governmental regulation.
The aerospace industry is highly regulated in the United States by the FAA and in other countries by similar agencies. We must be certified by the FAA and, in some cases, by individual OEMs in order to engineer and service parts, components and aerostructures used in specific aircraft models. If any of our material authorizations or approvals were revoked or suspended, our operations would be adversely affected. New or more stringent governmental regulations may be adopted, or industry oversight heightened in the future, and we may incur significant expenses to comply with any new regulations or any heightened industry oversight.
Our business could be materially adversely affected by product warranty obligations.
Our operations expose us to potential liability for warranty claims made by customers or third parties with respect to aircraft components that have been designed, manufactured, or serviced by us or our suppliers. Material product warranty obligations could have a material adverse effect on our business, financial condition and results of operations.
We may not realize our anticipated return on capital commitments made to expand our capabilities.
We continually make significant capital expenditures to implement new processes and to increase both efficiency and capacity. Some of these projects require additional training for our employees and not all projects may be implemented as

anticipated. If any of these projects do not achieve the anticipated increase in efficiency or capacity, our returns on these capital expenditures may be lower than expected.
Any product liability claims in excess of insurance may adversely affect our financial condition.
Our operations expose us to potential liability for personal injury or death as a result of the failure of an aircraft component that has been serviced by us or the failure of an aircraft component designed or manufactured by us. While we believe that our liability insurance is adequate to protect us from these liabilities, our insurance may not cover all liabilities. Additionally, as the number ofshould insurance companies providingmarket conditions change, general aviation product liability, insurance coverage has decreased in recent years, insurance coverage may not be available in the future at a cost acceptable to us. Any material liability not covered by insurance or for which third-party indemnification is not available could have a material adverse effect on our financial condition.
The lack of available skilled personnel may have an adverse effect on our operations.
From time to time, some of our operating locations have experienced difficulties in attracting and retaining skilled personnel to design, engineer, manufacture, repair and overhaul sophisticated aircraft components. Our ability to operate successfully could be jeopardized if we are unable to attract and retain a sufficient number of skilled personnel to conduct our business.
Our fixed-price contracts may commit us to unfavorable terms.
A significant portion of our net sales are derived from fixed-price contracts under which we have agreed to provide components or aerostructures for a price determined on the date we entered into the contract. Several factors may cause the costs we incur in fulfilling these contracts to vary substantially from our original estimates, and we bear the risk that increased or unexpected costs may reduce our profit or cause us to sustain losses on these contracts. In a fixed-price contract, we must fully absorb cost overruns, notwithstanding the difficulty of estimating all of the costs we will incur in performing these contracts. Because our ability to terminate contracts is generally limited, we may not be able to terminate our performance requirements under these contracts at all or without substantial liability and, therefore, in the event we are sustaining reduced profits or losses, we could continue to sustain these reduced profits or losses for the duration of the contract term. Our failure to anticipate technical problems, estimate delivery reductions, estimate costs accurately or control costs during performance of a fixed-price contract may reduce our profitability or cause significant losses on programs similar in nature to the forward losses incurred on the Boeing 747-8 ("747-8 program") and Bombardier Global 7000/8000 contracts.
Due to the size and long-term nature of many of our contracts, we are required by GAAP to estimate sales and expenses relating to these contracts in our financial statements, which may cause actual results to differ materially from those estimated under different assumptions or conditions.
Our financial statements are prepared in conformity with accounting principles generally accepted in the United States ("GAAP"). These principles require our management to make estimates and assumptions regarding our contracts that affect the reported amounts of revenue and expenses during the reporting period. Contract accounting requires judgment relative to assessing risks, estimating contract sales and costs, and making assumptions for schedule and technical issues. Due to the size and nature of many of our contracts, the estimation of total sales and cost at completion is complicated and subject to many variables. While we base our estimates on historical experience and on various assumptions that we believe to be reasonable under the circumstances at the time made, actual results may differ materially from those estimated.
Any exposure to environmental liabilities may adversely affect us.
Our business, operations and facilities are subject to numerous stringent federal, state, local, and foreign environmental laws and regulations, and we are subject to potentially significant fines or penalties, including criminal sanctions, if we fail to comply with these requirements. In addition, we could be affected by future laws and regulations, including those imposed in response to climate change concerns and other actions commonly referred to as "green initiatives." Compliance with current and future environmental laws and regulations currently requires and is expected to continue to require significant operating and capital costs.
Pursuant to certain environmental laws, a current or previous owner or operator of a contaminated site may be held liable for the entire cost of investigation, removal or remediation of hazardous materials at such property, whether or not the owner or operator knew of, or was responsible for, the presence of any hazardous materials. Although management believes that our operations and facilities are in material compliance with such laws and regulations, future changes in such laws, regulations or interpretations thereof or the nature of our operations or regulatory enforcement actions which may arise, may require us to make significant additional capital expenditures to ensure compliance in the future. Certain of our facilities, including facilities acquired and operated by us or one of our subsidiaries, have at one time or another been under active investigation for environmental contamination by federal or state agencies when acquired and, at least in some cases, continue to be under

investigation or subject to remediation for potential or identified environmental contamination. Lawsuits, claims and costs involving environmental matters are likely to continue to arise in the future. Individual facilities of ours have also been subject to investigation on occasion for possible past waste disposal practices which might have contributed to contamination at or from remote third-party waste disposal sites. In some instances, we are indemnified by prior owners or operators and/or present owners of the facilities for liabilities which we incur as a result of these investigations and the environmental contamination found which pre-dates our acquisition of these facilities, subject to certain limitations, including, but not limited to specified exclusions, deductibles and limitations on the survival period of the indemnity. We also maintain a pollution liability policy that provides coverage, subject to specified limitations, for specified material liabilities associated with the clean-up of certain on-site pollution conditions, as well as defense and indemnity for certain third-party suits (including Superfund liabilities at third-party sites), in each case, to the extent not otherwise indemnified. Also, as we proceed with our plans to exit certain facilities as part of restructuring and related initiatives, the need for remediation for potential environmental contamination could be identified. However, if we are required to pay the expenses related to environmental liabilities because neither indemnification nor insurance coverage is available, these expenses could have a material adverse effect on our financial position, results of operations, and cash flows.
Our expansion into international markets may increase credit, currency and other risks, and our current operations in international markets expose us to such risks.
As we pursue customers in Asia, South America and other less developed aerospace markets throughout the world, our inability to ensure the creditworthiness of our customers in these areas could adversely impact our overall profitability. In addition, with operations in Canada, China, France, Germany, Ireland, Mexico, Thailand and the United Kingdom, and customers throughout the world, we will be subject to the legal, political, social and regulatory requirements, and economic conditions of other jurisdictions. In the future, we may also make additional international capital investments, including further acquisitions of companies outside the United States or companies having operations outside the United States. Risks inherent to international operations include, but are not limited to, the following:
difficulty in enforcing agreements in some legal systems outside the United States;
imposition of additional withholding taxes or other taxes on our foreign income, tariffs or other restrictions on foreign trade and investment, including currency exchange controls;
fluctuations in exchange rates which may affect demand for our products and services and may adversely affect our profitability in U.S. dollars;
inability to obtain, maintain or enforce intellectual property rights;
changes in general economic and political conditions in the countries in which we operate;
unexpected adverse changes in the laws or regulatory requirements outside the United States, including those with respect to environmental protection, export duties and quotas;
failure by our employees or agents to comply with U.S. laws affecting the activities of U.S. companies abroad;
difficulty with staffing and managing widespread operations; and

difficulty of and costs relating to compliance with the different commercial and legal requirements of the countries in which we operate.
Our acquisition strategy exposes us to risks, including the risk that we may not be able to successfully integrate acquired businesses.
We have historically had a strategy to grow, in part, through the acquisition of additional businesses in the aerospace industry and are continuously evaluating various acquisition opportunities, including those outside the United States and those that may have a material impact on our business. Our ability to grow by acquisition is dependent upon, among other factors, the availability of suitable acquisition candidates. Growth by acquisition involves risks that could adversely affect our operating results, including difficulties in integrating the operations and personnel of acquired companies, the risk of diverting the attention of senior management from our existing operations, the potential amortization of acquired intangible assets, the potential impairment of goodwill and the potential loss of key employees of acquired companies. We may not be able to consummate acquisitions on satisfactory terms or, if any acquisitions are consummated, successfully integrate these acquired businesses.
Due to the size and long-term nature of many of our contracts, we are required by GAAP to estimate sales and expenses relating to these contracts in our financial statements, which may cause actual results to differ materially from those estimated under different assumptions or conditions.
Our consolidated financial statements are prepared in conformity with accounting principles generally accepted in the United States ("GAAP"). These principles require our management to make estimates and assumptions regarding our contracts that affect the reported amounts of revenue and expenses during the reporting period. Contract accounting requires judgment relative to assessing risks, estimating contract sales and costs, and making assumptions for schedule and technical issues. Due to the size and nature of many of our contracts, the estimation of total sales and cost at completion is complicated and subject to many variables. While we base our estimates on historical experience and on various assumptions that we believe to be reasonable under the circumstances at the time made, actual results may differ materially from those estimated.
We could become involved in intellectual property litigation, which could have a material and adverse impact on our profitability.
We and other companies in our industry possess certain proprietary rights relating to designs, engineering, manufacturing processes and repair and overhaul procedures. In the event that we believe that a third party is infringing upon our proprietary rights, we may bring an action to enforce such rights. In addition, third parties may claim infringement by us with respect to their proprietary rights and may initiate legal proceedings against us in the future. The expense and time of bringing an action to enforce such rights or defending against infringement claims can be significant. Intellectual property litigation involves complex legal and factual questions which makes the outcome of any such proceedings subject to considerable uncertainty. Not only can such litigation divert management's attention, but it can also expose the Company to damages and potential injunctive relief which, if granted, may preclude the Company from making, using or selling particular products or technology. The expense and time associated with such litigation may have a material and adverse impact on our profitability.
We do not own certain intellectual property and tooling that is important to our business.
In our overhaul and repair businesses, OEMs of equipment that we maintain for our customers include language in repair manuals relating to their equipment asserting broad claims of proprietary rights to the contents of the manuals used in our operations. Although we believe that our use of manufacture and repair manuals is lawful, there can be no assurance that OEMs will not try to enforce such claims, including through the possible use of legal proceedings, or that any such actions will be unsuccessful.
Our business also depends on using certain intellectual property and tooling that we have rights to use pursuant to license grants under our contracts with our OEM customers. These contracts contain restrictions on our use of the intellectual property and tooling and may be terminated if we violate certain of these restrictions. Our loss of a contract with an OEM customer and the related license rights to use an OEM's intellectual property or tooling would materially adversely affect our business.
Any significant disruption from key suppliers of raw materials and key components could delay production and decrease revenue.
We are highly dependent on the availability of essential raw materials such as carbon fiber, aluminum and titanium, and purchased engineered component parts from our suppliers, many of which are available only from single customer-approved sources. Moreover, we are dependent upon the ability of our suppliers to provide raw materials and components that meet our specifications, quality standards and delivery schedules. Our suppliers' failure to provide expected raw materials or component parts could require us to identify and enter into contracts with alternate suppliers that are acceptable to both us and our customers, which could result in significant delays, expenses, increased costs and management distraction and adversely affect production schedules and contract profitability.
We have from time to time experienced limited interruptions of supply, and we may experience a significant interruption in the future. Our continued supply of raw materials and component parts are subject to a number of risks including:
availability of capital to our suppliers;
the destruction of our suppliers' facilities or their distribution infrastructure;
a work stoppage or strike by our suppliers' employees;
the failure of our suppliers to provide raw materials or component parts of the requisite quality;

the failure of essential equipment at our suppliers' plants;
the failure or shortage of supply of raw materials to our suppliers;
contractual amendments and disputes with our suppliers; and
geopolitical conditions in the global supply base.
In addition, some contracts with our suppliers for raw materials, component parts and other goods are short-term contracts, which are subject to termination on a relatively short-term basis. The prices of our raw materials and component parts fluctuate depending on market conditions, and substantial increases in prices could increase our operating costs, which, as a result of our fixed-price contracts, we may not be able to recoup through increases in the prices of our products.
Due to economic difficulty, we may face pressure to renegotiate agreements resulting in lower margins. Our suppliers may discontinue provision of products to us at attractive prices or at all, and we may not be able to obtain such products in the future from these or other providers on the scale and within the time periods we require. Furthermore, substitute raw materials or component parts may not meet the strict specifications and quality standards we and our customers demand, or that the U.S. Government requires. If we are not able to obtain key products on a timely basis and at an affordable cost, or we experience significant delays or interruptions of their supply, revenues from sales of products that use these supplies will decrease.
Our operations depend on our manufacturing facilities, which are subject to physical and other risks that could disrupt production.
Our manufacturing facilities or our customers' facilities could be damaged or disrupted by a natural disaster, war, or terrorist activity. We maintain property damage and business interruption insurance at the levels typical in our industry or for our customers and suppliers, however, a major catastrophe, such as an earthquake, hurricane, fire, flood, tornado or other natural disaster at any of our sites, or war or terrorist activities in any of the areas where we conduct operations could result in a prolonged interruption of our business. Any disruption resulting from these events could cause significant delays in shipments

of products and the loss of sales and customers and we may not have insurance to adequately compensate us for any of these events. For leased facilities, timely renewal of leases and risk mitigation from the sale of our leased facilities is required to avoid any business interruption.
Our reputation, our ability to do business couldand our financial position, results of operations and/or cash flows may be negatively affectedimpacted by cyberthe improper conduct of employees, agents, subcontractors, suppliers, business partners or joint ventures in which we participate.
We have implemented policies, procedures, training and other compliance controls, and have negotiated terms designed to prevent misconduct by employees, agents or others working on our behalf or with us that would violate the applicable laws of the jurisdictions in which we operate, including laws governing improper payments to government officials, the protection of export controlled or classified information, cost accounting and billing, competition and data privacy. However, we cannot ensure that we will prevent all such misconduct committed by our employees, agents, subcontractors, suppliers, business partners or others working on our behalf or with us, and this risk of improper conduct may increase as we expand globally. In the ordinary course of our business we form and are members of joint ventures. We may be unable to prevent misconduct or other security threatsviolations of applicable laws by these joint ventures (including their officers, directors and employees) or other disruptions.
Our businesses depend heavily on information technology and computerized systems to communicate and operate effectively. The Company's systems and technologies,our partners. Improper actions by those with whom or those of third parties on whichthrough whom we rely, could fail or become unreliable due to equipment failures, software viruses, cyber threats, terrorist acts, natural disasters, power failures or other causes. These threats arise in some cases as a result ofdo business (including our role as a defense contractor.
Cybersecurity threats are evolving and include, but are not limited to, malicious software, attempts to gain unauthorized access to our sensitive information, including that of our customers,employees, agents, subcontractors, suppliers, subcontractors,business partners and joint venture partners,ventures) could subject us to administrative, civil or criminal investigations and other electronic security breaches thatmonetary and non-monetary penalties, including suspension and debarment, which could leadnegatively impact our reputation and ability to disruptions in mission critical systems, unauthorized release of confidential or otherwise protected information, and corruption of data.
Although we utilize various procedures and controls to monitor and mitigate these threats, there can be no assurance that these procedures and controls will be sufficient to prevent security threats from materializing. If any of these events were to materialize, the costs related to cyber or other security threats or disruptions may not be fully insured or indemnifiedconduct business and could have a material adverse effect on our reputation, operatingfinancial position, results and financial condition.
Significant consolidation by aerospace industry suppliers could adversely affect our business.
The aerospace industry continues to experience consolidation among suppliers and customers, primarily the airlines. Suppliers have consolidated and formed alliances to broaden their product and integrated system offerings and achieve critical mass. This supplier consolidation is in part attributable to aircraft manufacturers more frequently awarding long-term sole-source of operations and/or preferred supplier contracts to the most capable suppliers, thus reducing the total number of suppliers. This consolidation could cause us to compete against certain competitors with greater financial resources, market penetration and purchasing power. When we purchase component parts and services from suppliers to manufacture our products, consolidation reduces price competition between our suppliers, which could diminish incentives for our suppliers to reduce prices. If this consolidation continues, our operating costs could increase and it may become more difficult for us to be successful in obtaining new customers.


cash flows.
We may be subject to work stoppages at our facilities or those of our principal customers and suppliers, which could seriously impact the profitability of our business.
At March 31, 20162018, we employed 14,60213,554 people, of which 13.1%16.9% belonged to unions. Our unionized workforces and those of our customers and suppliers may experience work stoppages. For example, Theduring the quarter ended June 30, 2016, we settled a strike and agreed to a new collective bargaining agreement with our union employees with the IAM District 751 at our Spokane, Washington facility has expired. As of May 11, 2016,which had expired during the workforce in Spokane of approximately 400 employee has elected to strike.quarter. While we are currentlywere in negotiations with the workforce, we have implementedwere able to implement plans that allowed us to continue production in Spokane with the support from our other locations. Our union employees with Local 848 at our Red Oak, Texas and Local 952 at our Tulsa, Oklahoma, facilities of the United Auto Workers ("UAW") are currently working without a contract. If we are unable to negotiate a contract with those workforces, our operations may be disrupted and we may be prevented from completing production and delivery of products from those facilities, which would negatively impact our results. Contingency plans have been developed that would allow production to continue in the event of a strike.
Many aircraft manufacturers, airlines and aerospace suppliers have unionized workforces. Strikes, work stoppages or slowdowns experienced by aircraft manufacturers, airlines or aerospace suppliers could reduce our customers' demand for our products or prevent us from completing production. In turn, this may have a material adverse effect on our financial condition, results of operations and cash flows.
Financial market conditions may adversely affect the benefit plan assets for our defined benefit plans, increase funding requirements and materially impact our statements of financial position and cash flows.
Our benefit plan assets are invested in a diversified portfolio of investments in both the equity and debt categories, as well as limited investments in other alternative investments. The current market values of all of these investments, as well as the related benefit plan liabilities are impacted by the movements and volatility in the financial markets. In accordance with the Compensation—Retirement Benefits topic of the Accounting Standards Codification ("ASC"), we have recognized the over-fundedoverfunded or under-fundedunderfunded status of a defined benefit postretirement plan as an asset or liability on our balance sheet, and will recognize changes in that funded status in the year in which the changes occur. The funded status is measured as the difference between the fair value of the plan's assets and the projected benefit obligation. A decrease in the fair value of these plan assets or a decrease in interest rates resulting from movements in the financial markets will increase the under-fundedunderfunded status of the plans recorded on our statement of financial positionConsolidated Balance Sheets and result in additional cash funding requirements to meet the minimum required funding levels.
The U.S. Governmentgovernment is a significant customer of our largest customers, and we and they are subject to specific U.S. Government contracting rules and regulations.
The military aircraft manufacturers' business, and by extension, our business, is affected by the U.S. Government'sgovernment's continued commitment to programs under contract with our customers. The terms of defense contracts with the U.S. Governmentgovernment generally permit the government to terminate contracts partially or completely, either for its convenience or if we default by failing to perform under the contract. Termination for convenience provisions provide only for our recovery of unrecovered costs incurred or committed, settlement expenses and profit on the work completed prior to termination. Termination for default provisions provide for the contractor to be liable for excess costs incurred by the U.S. Governmentgovernment in

procuring undelivered items from another source. On contracts where the price is based on cost, the U.S. Governmentgovernment 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. Governmentgovernment may adjust our contract-related costs and fees, including allocated indirect costs. In addition, under U.S. Governmentgovernment purchasing regulations, some of our costs, including most financing costs, portions of research and development costs, and certain marketing expenses may not be subject to reimbursement.
We bear the potential risk that the U.S. Governmentgovernment may unilaterally suspend our customers or us from new contracts pending the resolution of alleged violations of procurement laws or regulations. Sales to the U.S. Governmentgovernment are also subject to changes in the government's procurement policies in advance of design completion. An unexpected termination of, or suspension from, a significant government contract, a reduction in expenditures by the U.S. Governmentgovernment for aircraft using our products, lower margins resulting from increasingly competitive procurement policies, a reduction in the volume of contracts awarded to us, or substantial cost overruns could have a material adverse effect on our financial condition, results of operations and cash flows.
We are subject to the requirements of the National Industrial Security Program Operating Manual for facility security clearance, which is a prerequisite for our ability to perform on classified contracts for the U.S. Government.
DoD facility security clearance is required in order to be awarded and perform on classified contracts for the DoD and certain other agencies of the U.S. Government, which is a significant part of our business. We have obtained clearance at

appropriate levels that require stringent qualifications, and we may be required to seek higher level clearances in the future. We cannot assure you that we will be able to maintain our security clearance. If for some reason our security clearance is invalidated or terminated, we may not be able to continue to perform our present classified contracts or be able to enter into new classified contracts, which could affect our ability to compete for and capture new business.
New regulationsRegulations related to conflict minerals have and will continue to force us to incur additional expenses, may make our supply chain more complex, and could adversely impact our business.
The Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 contains provisions to improve transparency and accountability concerning the supply of certain minerals and metals, known as conflict minerals, originating from the Democratic Republic of Congo (the "DRC") and adjoining countries. As a result, in August 2012, the SEC adopted annual investigation, disclosure and reporting requirements for those companies that manufacture or contract to manufacture products that contain conflict minerals that originated from the DRC and adjoining countries. We have and will continue to incur compliance costs, including costs related to determining the sources of conflict minerals used in our products and other potential changes to processes or sources of supply as a consequence of such verification activities. The implementation of these rules could adversely affect the sourcing, supply and pricing of materials used in certain of our products. As there may be only a limited number of suppliers offering "conflict free" minerals, we cannot be sure that we will be able to obtain necessary conflict-free minerals from such suppliers in sufficient quantities or at competitive prices. Also, we may face reputational challenges if we determine that certain of our products contain minerals not determined to be conflict free.
Our business is subject to regulation in the United States and internationally.
The manufacturing of our products is subject to numerous federal, state and foreign governmental regulations. The number of laws and regulations that are being enacted or proposed by various governmental bodies and authorities are increasing. Compliance with these regulations is difficult and expensive. If we fail to adhere, or are alleged to have failed to adhere, to any applicable federal, state or foreign laws or regulations, or if such laws or regulations negatively affect sales of our products, our business, prospects, results of operations, financial condition or cash flows may be adversely affected. In addition, our future results could be adversely affected by changes in applicable federal, state and foreign laws and regulations, or the interpretation or enforcement thereof, including those relating to manufacturing processes, product liability, government contracts, trade rules and customs regulations, intellectual property, consumer laws, privacy laws, as well as accounting standards and taxation requirements (including tax-rate changes, new tax laws or revised tax law interpretations.

On May 25, 2016,21, 2018, the reported closing price for our common stock was $37.78.$25.10. As of May 25, 2016,21, 2018, there were approximately 102 holders of record of our common stock and we believe that our common stock was beneficially owned by approximately 30,000 persons.

Dividend Policy
During fiscal 20162018 and 20152017, we paid cash dividends of $0.16 per share and $0.16 per share, respectively. However, our declaration and payment of cash dividends in the future and the amount thereof will depend upon our results of operations, financial condition, cash requirements, future prospects, limitations imposed by credit agreements or indentures governing debt securities and other factors deemed relevant by our Board of Directors. No assurance can be given that cash dividends will continue to be declared and paid at historical levels or at all. Certain of our debt arrangements, including the Credit Facility, restrict our paying dividends and making distributions on our capital stock, except for the payment of stock dividends and redemptions of an employee's shares of capital stock upon termination of employment. On May 2, 2016,The Company will likely have an accumulated deficit in the Company announced that its Boardfirst quarter of Directors declared a regular quarterly dividend of $0.04 per share on its outstanding common stock. The dividend is next payable on June 15, 2016,Fiscal 2019, which would limit or restrict our ability to stockholders of record as of May 31, 2016.pay dividends.
Repurchases of Stock
In December 1998, we announced a program to repurchase up to 500,000 shares of our common stock. In February 2008, the Company's Board of Directors authorized an increase in the Company's existing stock repurchase program by up to an additional 500,000 shares of its common stock. In February 2014, the Company's Board of Directors authorized an increase in the Company's existing stock repurchase program by up to an additional 5,000,000 shares of its common stock. During the fiscal yearyears ended March 31, 2018, 2017 and 2016, we did not repurchase any shares. During the fiscal years ended March 31, 2015 and 2014, we repurchased 2,923,011 and 300,000 shares, respectively, for a purchase price of $184.4 million and $19.1 million, respectively. From the inception of the program through March 31, 2013, we repurchased 499,200 shares (prior to fiscal 2012 stock split) for a purchase price of $19.2 million. Repurchases may be made from time to time in open market transactions, block purchases, privately negotiated transactions or otherwise at prevailing prices. No time limit has been set for completion of the program. As a result, as of May 27, 2016,22, 2018, the Company remains able to purchase an additional 2,277,789 shares.

Item 7.Management's Discussion and Analysis of Financial Condition and Results of Operations
The following discussion should be read in conjunction with the Consolidated Financial Statements and notes thereto contained elsewhere herein.

OVERVIEW

Effective January 1, 2018, we combined our Aerospace Structures and Precision Components operating segments into one reporting segment, Aerospace Structures. Aerospace Structures and Precision Components share many of the same customers and suppliers and have substantial inter-company work on common programs. As a single operating segment, we are able to leverage their combined resources to make it more cost competitive and enhance performance. The newly formed operating segment is also a reportable segment. As a result, effective January 1, 2018, we have three reporting segments for financial reporting purposes - Integrated Systems, Product Support and Aerospace Structures.
We are a major supplier to the aerospace industry and have three operating segments: (i) Triumph Aerostructures Group,Integrated Systems, whose companies'companies’ revenues are derived from theintegrated solutions, including design, manufacture, assemblydevelopment and integrationsupport of proprietary components, subsystems and systems, as well as production of complex assemblies using external designs; (ii) Aerospace Structures, whose companies supply commercial, business, regional and military manufacturers with large metallic and composite aerostructuresstructures and structural components for the global aerospace original equipment manufacturers, or OEM, market; (ii) Triumph Aerospace Systems Group, whose companies design, engineerproduce close-tolerance parts primarily to customer designs and manufacturemodel based definition, including a wide range of proprietaryaluminum, hard metal and build-to-print components, assembliescomposite structure capabilities; and systems also(ii) Product Support, whose companies provide full life cycle solutions for commercial, regional and military aircraft.
In May 2018, the Company entered into a definitive agreement to divest Triumph Structures - Los Angles, Inc. ("TSLA") and Triumph Processing, Inc. ("TPI"). The transaction is subject to customary closing conditions and is expected to close in the first half of fiscal 2019. The operating results for TSLA and TPI were included in Aerospace Structures for the OEM market; and (iii) Triumph Aftermarket Services Group, whose companies serve aircraft fleets, notably commercial airlines, the U.S. military and cargo carriers, through the maintenance, repair and overhaul of aircraft components and accessories manufactured by third parties.fiscal year ended March 31, 2018.
Effective October 21, 2015,In March 2018, the Company acquired the ownership ofsold all of the outstanding shares of Fairchild Controls CorporationTriumph Structures Long Island, LLC ("Fairchild"TS-LI"). Fairchild for total cash proceeds of $9.5 million. As a result of the sale of TS-LI, the Company recognized a loss of $10.4 million which is a leading providerpresented on the accompanying Consolidated Statements of proprietary thermal management systems, auxiliary power generation systems and related aftermarket spares and repairs.Operations as "Loss on divestiture." The acquired business operates as Triumph Thermal Systems-Maryland, Inc. and itsoperating results areof TS-LI were included in Aerospace Systems Group fromStructures through the date of acquisition.disposal.
In September 2017, the Company sold all of the shares of Triumph Processing - Embee Division, Inc. ("Embee") for total cash proceeds of $65.0 million. As a result of the sale of Embee, the Company recognized a loss of $17.9 million, which is included in Corporate. The operating results of Embee were included in Integrated Systems through the date of disposal.
Significant financial results for the fiscal year ended March 31, 20162018, include:
Net sales for fiscal 20162018 decreased 0.1%9.4% to $3.89$3.20 billion,, including a 9.8%6.3% decrease in organic sales.
Operating loss for fiscal 20162018 was $(1.09) billion.$362.4 million.
Included in operating loss for fiscal 20162018 was a non-cash impairment chargecharges of $874.4$535.2 million primarily related to goodwill andassociated with the indefinite-lived tradename in the AerostructuresAerospace Structures reporting forward losses to the Bombardier Global 7000/8000 and 747-8 programs of $561.2 millionunit and restructuring and related accelerated depreciation charges of $81.0$43.1 million.
Net loss for fiscal 20162018 was $(1.05) billion and included a charge for an income tax valuation allowance of $155.8$425.4 million.

$4.50 billion.
For the fiscal year ended March 31, 2016,2018, net sales totaled $3.89$3.20 billion,, a 0.1%9.4% decrease from fiscal year 20152017 net sales of $3.89 billion. Net income$3.53 billion. The net loss for fiscal year 20162018 decreased 539.0%increased 890.4% to $(1.05) billion,$425.4 million, or $(21.29)$8.60 per diluted common share, versus $238.7the net loss of $43.0 million,, or $4.68$0.87 per diluted common share, for fiscal year 20152017.
Our working capital needs are generally funded through cash flows from operations and borrowings under our credit arrangements. For the fiscal year ended March 31, 20162018, we generatedused $83.9288.9 million of cash flows from operating activities,

usedreceived $128.038.2 million infrom investing activities and received $32.5213.6 million infrom financing activities. Cash flows from operating activities in fiscal year 2015 was $467.3 million and included $112.3 million in pension contributions.2017 were $281.5 million.
During the fiscal year ended March 31, 2016, theThe Company has committed to aseveral plans that incorporate the restructuring of certain its businesses as well as the consolidation of certain of its facilities ("2016 Restructuring Plan").facilities. The Company expects to reduce its footprint by approximately 3.54.3 million square feet and to reduce head count by 1,200 employees.2,500 employees, approximately 1,000 of which have exited as of March 31, 20188. Over the next fewcourse of these cost-reducing programs (which were initiated in fiscal years,2016), the Company estimates that it will record aggregate related pre-tax charges of $150.0$195.0 million to $160.0$210.0 million, related to these programs, which represent employee termination benefits, contract termination costs, accelerated depreciation and facility closure and other exit costs, and will result in future cash outlays. For the fiscal yearyears ended fiscal years ended March 31, 2018, 2017 and 2016, the Company recorded charges of $43.1 million, $53.0 million and $81.0 million, respectively, related to this program, including accelerated depreciationthese programs.
Our 2016 and 2017 restructuring plans and related activities are anticipated to generate annualized savings of $22.4approximately $300 million per year on a consolidated basis by fiscal year 2019 from facility consolidations, headcount reductions, operational efficiencies, and severancesupply chain optimization. These anticipated savings are expected to come from our reportable segments approximately as follows: Integrated Systems - 23%; Aerospace Structures - 72% and Product Support - 5%. A significant portion of $16.3 million.the anticipated savings are expected to be reinvested in business development, research and development and capital improvements to help drive organic growth. Through March 31, 2018, the Company is on target for its consolidated anticipated savings goals; however, the nature of those savings has shifted over time to be more weighted toward our supply chain optimization and operational efficiencies than previously anticipated, offset by reduced expectations associated with the facility consolidations and headcount reductions.
We are currently performing work on several new programs, which are in various stages of development. Several of the these programs are expected to enterhave entered flight testing, during our fiscal 2017, including the Bombardier Global 7000/8000 ("Global 7000/8000") and Embraer second generation E-Jet ("E2-Jets") and we expect to deliver revenue generating production units for these programs in late fiscal 2017, or early fiscalcalendar year 2018. Historically, low-rate production commences during flight testing, followed by an

increase to full-rate production, assuming that successful testing and certification are achieved. Accordingly, we anticipate that each of these programs will begin generating full-rate production level revenues between fiscal 2019 and fiscal 2021. We are still in the early development stages for the Gulfstream G500/G600 programs, as these aircraft are not expected to enter service until fiscal 2019. Transition of each of these programs from development to recurring production levels is dependent upon the success of each program at achieving flight testing and certification, as well as the ability of the OEM to generate acceptable levels of aircraft sales.
Fiscal 2016 was a challenging year for certain of our new programs. While work progressed on these development programs, we have experienced difficulties in achieving estimated cost targets particularly in the areas of engineering and estimated recurring costs. As described in more detail in “ResultsIn the fourth quarter of Operations”,fiscal 2016, we recorded a $399.8 million forward loss on our Bombardier Global 7000/8000 wing contract in the fourth quarter of 2016.contract. The Global 7000/8000 contract provides for fixed pricing and requires us to fund certain up-front development expenses, with certain milestone payments made by Bombardier.
The provision for forward losses on the Global 7000/8000 program charge resulted in the impairment of previously capitalized pre-production costs due to the combination of cost recovery uncertainty, higher than anticipated non-recurringnonrecurring costs and increased forecasted costs on recurring production. The increases in costs were driven by several factors, including: changing technical requirements, increased spending on the design and engineering phase of the program and uncertainty regarding cost reduction and cost recovery initiatives with our customer and suppliers. The program has continued to incur costs since March 2016 in support of development and transition to production.
On December 22, 2016, Triumph Aerostructures, LLC, the wholly owned subsidiary of the Company that is party to the Global 7000/8000 contract with Bombardier (“Triumph Aerostructures”), initiated litigation against Bombardier in the Quebec Superior Court, District of Montreal. The lawsuit related to Bombardier’s failure to pay to Triumph Aerostructures certain non-recurring expenses incurred by Triumph Aerostructures during the development phase of a program pursuant to which Triumph Aerostructures agreed to design, manufacture, and supply the wing and related components for Bombardier’s Global 7000 business aircraft.        
In May 2017, Triumph Aerostructures and Bombardier entered into a comprehensive settlement agreement that resolved all outstanding commercial disputes between them, including all pending litigation, related to the design, manufacture and supply of wing components for Bombardier’s Global 7000 business aircraft. The settlement reset the commercial relationship between the companies and allowed each company to better achieve its business objectives going forward.

Further cost increases or an inability to meet revised recurring cost forecasts on the Global 7000/8000 program may result in additional forward loss reserves in future periods, while improvements in future costs compared to current estimates or additional cost recovery may result in favorable adjustments if forward loss reserves are no longer required.
 Under our contract with Embraer, we have the exclusive right to design, develop and manufacture the center fuselage section III, rear fuselage section and various tail section components (rudder and elevator) for the E2-Jets over the initial 600 ship sets. The contract provides for funding on a fixed amount of non-recurringnonrecurring costs, which will be paid over a specified number of production units. Higher than expected spending on the E2-Jets program has resulted in a low single digitnear breakeven estimated profit margin percentage, with additional potential future cost pressures as well as opportunities for improved performance. While we still estimate positive margins for this contract, risksRisks related to additional engineering as well as the recurring cost profile remainsremain as this program enterscompletes flight testing. During the fiscal year ended March 31, 2018, the Company reached an agreement with AeroSpace Technologies of Korea Inc. (ASTK) to optimize the supply chain under our portion of the E2 program. Under this agreement, ASTK will build and transport fuselage shipsets to Embraer and establish a facility in Brazil to manage stock and repairs locally. The Company maintains its role as the supply chain integrator on the program.
We seek additional consideration for customer work statement changes throughout the development process as a standard course of business. The ability to recover or negotiate additional consideration is not certain and varies by contract. Varying market conditions for these products may also impact future profitability.
Although none of these new programs individually are expected to have a material impact on our net revenues, they do have the potential, either individually or in the aggregate, to materially and negatively impact our consolidated results of operations if future changes in estimates result in the need for a forward loss provision. Absent any such loss provisions, we do not anticipate that any of these new programs will significantly dilute our future consolidated margins.
In JanuaryMarch 2017, the Company settled several outstanding change orders and open pricing on a number of its programs with Boeing. The agreement included pricing settlements, advanced payments, delivery schedule adjustments and the opportunity to extend the mutual relationship on future programs. The agreement also provides for continued build ahead on the 747-8 program through the end of the existing contract, resulting in a reduction to the previously recognized forward losses on the 747-8 program.
As disclosed during fiscal 2016, Boeing announced a rate reduction to the 747-8 program, which lowerslowered production to one plane every two months. We have assessedmonths, the impact of the rate reduction and have recordedresulted in an additional $161.4 million forward loss during the quarterfiscal year ended March 31, 2016. This announcement follows
Subsequent to March 31, 2018, the September 2015 decision by BoeingCompany reached an agreement with Gulfstream to in-source production ofoptimize the 747-8 program beginning in the second half of fiscal 2019, effectively terminating this program with us after our current contract. Additional costs associated with exiting the facilities where the 747-8 program is manufactured, such as asset impairment, supplier and lease termination charges, as well as severance and retention payments to employees and contractors have been included in the 2016 Restructuring Plan.
As disclosed during fiscal 2015, we also recognized a provision for forward losses associated with our long-term contractsupply chain on the 747-8 program. There is still risk similar to what we have experiencedCompany's G650 work scope. The G650 wing box and wing completion work, which are now co-produced across three facilities at both companies, are planned for consolidation into Gulfstream’s structures center of excellence in Savannah. The Company will maintain its role as the supply chain integrator on the 747-8 program. Particularly, our ability to manage risks related to supplier performance, execution of cost reduction strategies, hiring and retaining skilled production and management personnel, quality and manufacturing execution, program schedule delays and many other risks, will determine the ultimate performance of these long-term programs.
Consistent with ourthe Company's policy described in our Critical Accounting Policies here within, we performed Step 1 ofNote 2, the goodwill impairment testCompany performs an annual assessment in its fiscal fourth quarter and on an interim basis upon the occurrence of events or substantive changes in circumstances that indicate a reporting unit's faircarrying value may be less than its carryingfair value. During the third quarter of fiscal 2016, weThe Company performed an interim assessment of the fair value of ourits goodwill and indefinite-lived intangible assets due to the Company's decision to combine the Aerospace Structures and Precision Components reporting segments into one reporting segment as noted above. In accordance with ASC 350-20-35-3C, there are several potential events and circumstances that could be indicators of impairment related to the continued declinegoodwill impairment. A change in our stock price during the third quarter.

Our assessment focused on the Aerostructuresa company's reporting unit sincestructure is one of these events, and when this does occur, a company must perform a "before and after" test of the reporting units (see Note 1). Additionally, the Company's enhanced visibility into its future cash flows based on its annual planning process was also an indicator. Consistent with the Company's policy, it had significant changes in its economic indicators and adjusted for select changes inperformed the risk adjusted discount rate to considergoodwill impairment test which includes using a combination of both the current return requirements of the market and the risks inherent in the reporting unit, expected long-term growth rate and cash flow projectionsincome approaches to determine if any decline inestimate the estimated fair value of aeach reporting unit.
After performing the "before" portion of the test of the reporting units the Company concluded that the former Precision Components' reporting unit couldhad a fair value that was lower than its carrying value by an amount of $190.2 million. Accordingly, the Company recorded a non-cash impairment charge during the fiscal quarter ended December 31, 2017, of $190.2 million, which is presented on the accompanying Consolidated Statements of Operations as "Impairment of intangible assets”. The decline in fair value is the result of declining revenues from production rate reductions on sun-setting programs and the slower than previously projected ramp in our development programs and the timing of associated earnings and cash flows.

The Company then performed the "after" portion of the test of the reporting units and concluded that the new reporting unit of Aerospace Structures' goodwill had a fair value that was lower than its carrying value by an amount that exceeded the remaining goodwill impairment. Wefor the reporting unit. Following the applicable accounting guidance, this impairment charge is deemed to have occurred during the Company's fiscal fourth quarter. Therefore, the Company recorded a non-cash impairment charge during the fiscal quarter ended March 31, 2018, of $345.0 million, which is presented on the Consolidated Statements of Operations as "Impairment of intangible assets” for the fiscal year ended March 31, 2018. The decline in fair value is the result of declining revenues from production rate reductions on sun-setting programs and the slower than previously projected ramp in our development programs and the timing of associated earnings and cash flows (See Note 2 for definition of fair value levels).
In the fourth quarter of the fiscal year ended March 31, 2017, we concluded that the goodwill related to the Aerospace Structures reporting unit was not impaired as of the interimannual testing date. We recorded a non-cash impairment assessment date. However,charge during the excessfourth quarter of the fair value overfiscal year ending March 31, 2017, of $266.3 million, which is presented on the carrying value was within 5% for the Company's Aerostructures reporting unit. The amountaccompanying Consolidated Statements of goodwill for our Aerostructures reporting unit amounted to $1.42 billionOperations as "Impairment of the interim testing date.intangible assets.”
DuringIn the fourth quarter of the fiscal year ended March 31, 2016, consistent with our policy described herein, we performed our annual assessment of the fair value of our goodwill for each of our three reporting units. We concluded that the goodwill of our AerostructuresAerospace Structures reporting unit was impaired as of the annual testing date. We concluded that the goodwill had an implied fair value of $822.8 million (Level 3) compared to a carrying value of $1.42 billion. Accordingly, weWe recorded a non-cash impairment charge during the fourth quarter of fiscal 2016 of $597.6 million, which is presented on the accompanying Consolidated Statements of Operations as "Impairment of intangible assets". The decline in fair value is the result of continued declines in stock price and related market multiples for stock price to EBITDA of both the Company and our peer group. Going forward, we will continue to monitor the performance of this reporting unit in relation to the key assumptions in our analysis.
In the event that market multiples for stock price to EBITDA in the aerospace and defense markets decrease, or the expected EBITDA and cash flows for our reporting units decreases, an additional goodwill impairment charge may be required, which would adversely affect our operating results and financial condition. If management determines that impairment exists, the impairment will be recognized in the period in which it is identified.assets."
During the third quarter of the fiscal year ended March 31, 2016, we performed an interim assessment of fair value on our indefinite-lived intangible assets due to potential indicators of impairment related to the continued decline in our stock price during the fiscal third quarter. We estimated the fair value of the tradenames using the relief-from-royalty method, which uses several significant assumptions, including revenue projections that consider historical and estimated future results, general economic and market conditions, as well as the impact of planned business and operational strategies. The following estimates and assumptions were also used in the relief-from-royalty method:
Royalty rates between 2% and 4% based on market observed royalty rates and profit split analysis; and
Discount rates between 12% and 13% based on the required rate of return for the tradename assets.
Based on our evaluation, we concluded that the Vought tradename had a fair value of $195.8 million (Level 3) compared to a carrying value of $425.0 million. Accordingly, we recorded a non-cash impairment charge during the quarter ended December 31, 2015, of $229.2 million, which is presented on the accompanying Consolidated Statements of Operations as "Impairment of intangible assets". The decline in fair value compared to carrying value of the Vought tradename is the result of declining revenues from production rate reductions and the slower than previously projected ramp in Bombardier Global 7000/8000 and the timing of associated earnings.
During the fourth quarter of the fiscal year ended March 31, 2016, we performed our annual assessment of fair value on our indefinite-lived intangible assets. We estimated the fair value of the tradenames using the relief-from-royalty method, which uses several significant assumptions, including revenue projections that consider historical and estimated future results, general economic and market conditions, as well as the impact of planned business and operational strategies. The following estimates and assumptions were also used in the relief-from-royalty method:
Royalty rates between 2% and 4% based on market observed royalty rates and profit split analysis; and
Discount rate of 14% based on the required rate of return for the tradename assets, which increased from our interim assessment driven by increased risk due to continued declines in stock price and related market multiples for stock price to EBITDA of both the Company and our peer group and increased interest rates.
Based on our evaluation of indefinite-lived assets, including the tradenames, we concluded that the Vought and Embee tradenames had a fair value of $163.0 million (Level 3) compared to a carrying value of $209.2 million. The decline in fair value compared to carrying value of the tradenames is the result of the increase in discount rate during the fourth quarter, which required the Company to assess whether events and/or circumstances have changed regarding the indefinite-life conclusion. Accordingly, we revalued both the tradenames as if these intangible assets were no longer indefinite and recorded a non-cash impairment charge during the fiscal year ended March 31, 2016, of $46.2 million, which is presented on the accompanying Consolidated Statements of Operations as "Impairment of intangible assets". Additionally, we
During the fiscal year ended March 31, 2017, as part of the Company's annual assessment, the Company determined that the tradenames will be amortized over their remaining estimated useful life for the Vought tradename should be reduced from a useful life of 20 years.years to a useful life of 10 years, as it better represents the expected period of benefit to the Company's financial performance.

In the event of significant loss of revenues and related earnings associated with the Vought and Embee tradenames,tradename, further impairment charges may be required, which would adversely affect our operating results.
TheDuring the quarter ended June 30, 2016, we settled a strike and agreed to a new collective bargaining agreement with our union employees with IAM District 751 at our Spokane, Washington facility has expired. Aswhich had expired during the quarter, resulting in a charge of May 11, 2016,$15.7 million due to disruption costs. During the workforce in Spokane of approximately 400 employees has elected to strike. While we are currently in negotiationsfiscal year ended March 31, 2018, the Company ratified a collective bargaining agreement with the workforce, we have implemented plans to continue production in Spokane with support from other locations. Ourits union employees with UAWUnited Autoworkers of America and its Local Union 848 at ourits Red Oak, Texas facilityfacility.
Subsequent to the fiscal year ended March 31, 2018, the Company ratified a collective bargaining agreement with its union employees with United Autoworkers of America and UAWits Local Union 952 at ourits Tulsa, Oklahoma facilityfacility.

RESULTS OF OPERATIONS
The following includes a discussion of our consolidated and business segment results of operations. The Company's diverse structure and customer base do not provide for precise comparisons of the impact of price and volume changes to our results. However, we have disclosed the significant variances between the respective periods.
Non-GAAP Financial Measures
We prepare and publicly release quarterly unaudited financial statements prepared in accordance with GAAP. In accordance with Securitiesthe SEC guidance and Exchange Commission (the "SEC") guidance onthe SEC's Compliance and Disclosure Interpretations, we also disclose and discuss certain non-GAAP financial measures in our public filings and press releases. Currently, the non-GAAP financial measure that we disclose is Adjusted EBITDA, which is our (loss) income from continuing operations before interest, income taxes, amortization of acquired contract liabilities, curtailments, settlements and early retirement incentives and depreciation and amortization. We disclose Adjusted EBITDA on a consolidated and a reportable segment basis in our earnings releases, investor conference calls and filings with the SEC. The non-GAAP financial measures that we use may not be comparable to similarly titled measures reported by other companies. Also, in the future, we may disclose different non-GAAP financial measures in order to help our investors more meaningfully evaluate and compare our future results of operations to our previously reported results of operations.
We view Adjusted EBITDA as an operating performance measure and, as such, we believe that the GAAP financial measure most directly comparable to it is (loss) income from continuing operations. In calculating Adjusted EBITDA, we exclude from (loss) income from continuing operations the financial items that we believe should be separately identified to provide additional analysis of the financial components of the day-to-day operation of our business. We have outlined below the type and scope of these exclusions and the material limitations on the use of these non-GAAP financial measures as a result of these exclusions. Adjusted EBITDA is not a measurement of financial performance under GAAP and should not be considered as a measure of liquidity, as an alternative to net (loss) income, (loss) income from continuing operations, or as an indicator of any other measure of performance derived in accordance with GAAP. Investors and potential investors in our securities should not rely on Adjusted EBITDA as a substitute for any GAAP financial measure, including net (loss) income or (loss) income from

continuing operations. In addition, we urge investors and potential investors in our securities to carefully review the reconciliation of Adjusted EBITDA to (loss) income from continuing operations set forth below, in our earnings releases and in other filings with the SEC and to carefully review the GAAP financial information included as part of our Quarterly Reports on Form 10-Q and our Annual Reports on Form 10-K that are filed with the SEC, as well as our quarterly earnings releases, and compare the GAAP financial information with our Adjusted EBITDA.
Adjusted EBITDA is used by management to internally measure our operating and management performance and by investors as a supplemental financial measure to evaluate the performance of our business that, when viewed with our GAAP results and the accompanying reconciliation, we believe provides additional information that is useful to gain an understanding of the factors and trends affecting our business. We have spent more than 20 years expanding our product and service capabilities partially through acquisitions of complementary businesses. Due to the expansion of our operations, which included acquisitions, our (loss) income from continuing operations has included significant charges for depreciation and amortization. Adjusted EBITDA excludes these charges and provides meaningful information about the operating performance of our business, apart from charges for depreciation and amortization. We believe the disclosure of Adjusted EBITDA helps investors meaningfully evaluate and compare our performance from quarter to quarter and from year to year. We also believe Adjusted EBITDA is a measure of our ongoing operating performance because the isolation of non-cash charges, such as depreciation and amortization, and non-operating items, such as interest and income taxes, provides additional information about our cost structure, and, over time, helps track our operating progress. In addition, investors, securities analysts and others have regularly relied on Adjusted EBITDA to provide a financial measure by which to compare our operating performance against that of other companies in our industry.
Set forth below are descriptions of the financial items that have been excluded from our (loss) income from continuing operations to calculate Adjusted EBITDA and the material limitations associated with using this non-GAAP financial measure as compared to (loss) income from continuing operations:
Divestitures may be useful for investors to consider because they reflect gains or losses from sale of operating units. We do not believe these earnings necessarily reflect the current and ongoing cash earnings related to our operations.
Legal settlements may be useful for investors to consider because it reflects gains or losses from disputes with third parties. We do not believe these earnings necessarily reflect the current and ongoing cash earnings related to our operations.

Curtailments, settlements and early retirement incentives may be useful for investors to consider because it represents the current period impact of the change in the defined benefit obligation due to the reduction in future service costs as well as the incremental cost of retirement incentive benefits paid to participants. We do not believe these earnings necessarily reflect the current and ongoing cash earnings related to our operations.
Amortization of acquired contract liabilities may be useful for investors to consider because it represents the non-cash earnings on the fair value of off-market contracts acquired through acquisitions. We do not believe these earnings necessarily reflect the current and ongoing cash earnings related to our operations.
Amortization expense (including intangible asset impairments) may be useful for investors to consider because it represents the estimated attrition of our acquired customer base and the diminishing value of product rights and licenses. We do not believe these charges necessarily reflect the current and ongoing cash charges related to our operating cost structure.
Depreciation may be useful for investors to consider because it generally represents the wear and tear on our property and equipment used in our operations. We do not believe these charges necessarily reflect the current and ongoing cash charges related to our operating cost structure.
The amount of interest expense and other we incur may be useful for investors to consider and may result in current cash inflows or outflows. However, we do not consider the amount of interest expense and other to be a representative component of the day-to-day operating performance of our business.
Income tax expense may be useful for investors to consider because it generally represents the taxes which may be payable for the period and the change in deferred income taxes during the period and may reduce the amount of funds otherwise available for use in our business. However, we do not consider the amount of income tax expense to be a representative component of the day-to-day operating performance of our business.
Management compensates for the above-described limitations of using non-GAAP measures by using a non-GAAP measure only to supplement our GAAP results and to provide additional information that is useful to gain an understanding of the factors and trends affecting our business.

Net sales decreased by $2.7333.8 million, or (0.1)%9.4%, to $3.93.2 billion for the fiscal year ended March 31, 20162018, from $3.93.5 billion for the fiscal year ended March 31, 20152017. Organic sales adjusted for inter-segment sales decreased $218.4 million, or 6.4%. The acquisitiondivestitures of FairchildTAS-Newport News and Engines and APU contributed $110.5 million to the net sales decrease as compared to the prior fiscal 2015 acquisitions contributed $355.3 million.year. Organic sales decreased $352.7 million, or (9.8)%, due to production rate cuts by our customers on the 747-8, V-22, G450/G550 and C-17 programs. The prior fiscal year was negatively impacted by our customers' decreased production rates on existing programs and decreased military sales.
In the fourth quarter of fiscal 2016, we recorded a $399.8 million forward loss charge for the Bombardier Global 7000/8000 wing program. Under our contract for this program, we have the right to design, develop and manufacture wing components over the initial 300 ship sets. The Global 7000/8000 contract provides for fixed pricing and requires us to fund certain up-front development expenses, with certain milestone payments made by Bombardier. The Global 7000/8000 program charge resulted in the impairment of previously capitalized pre-production costsprimarily due to the combinationcompletion of cost recovery uncertainty, higher than anticipated non-recurring costs and continued rate reductions on certain Boeing and Gulfstream programs, along with the timing of deliveries on certain programs. These factors were partially offset by increased forecasted costs on recurring production. The increases in costs were driven by several factors, including: changing technical requirements, increased spendingproduction on the design and engineering phase of the program and uncertainty regarding cost reduction and cost recovery initiatives with our customer and suppliers. Further cost increases or an inability to meet revised recurring cost forecasts on the Global 7000/8000 program may result in additional forward loss reserves in future periods, while improvements in future costs compared to current estimates may result in favorable adjustments if forward loss reserves are no longer required.
In January 2016, Boeing announced a rate reduction to the 747-8 program, which lowers production to one plane every two months. We have assessed the impact of the rate reduction and have recorded an additional $161.4 million forward loss. This announcement follows the September 2015 decision by Boeing to in-source production of the 747-8 program beginning in the second half of fiscal 2019, effectively terminating this program with us after our current contract. Additional costs associated with exiting the facilities where the 747-8 program is manufactured, such as asset impairment, supplier and lease termination charges, as well as severance and retention payments to employees and contractors have been included in the 2016 Restructuring Plan.
Recognition of additional forward losses in the future periods continues to be a risk and will depend upon several factors, including the impact of the above discussed production rate change, our ability to successfully perform under current design and manufacturing plans, achievement of forecasted cost reductions as we continue production, our ability to successfully resolve claims and assertions with our customers and suppliers and our customers' ability to sell their products.767/Tanker program.
Cost of sales decreased by $156.7 million, or 5.8%, to $2.5 billion for the fiscal year ended March 31, 2018, from $2.7 billion for the fiscal year ended increasedMarch 31, 2017. Organic cost of sales adjusted for inter-segment sales decreased $69.4 million or 2.7%. The divestitures of TAS-Newport News, Embee and Engines and APU contributed $80.7 million to the cost of sales decrease as compared to the prior fiscal year. Organic gross margin for the fiscal year ended March 31, 2018, was 20.6% compared with 23.7% for the fiscal year ended March 31, 2017. The gross margin for the fiscal year ended March 31, 2018, decreased compared to the comparable prior year period due to the completion of certain Boeing and Gulfstream programs as noted above.
Gross margin included net favorable cumulative catch-up adjustments on long-term contracts of $19.7 million. The favorable cumulative catch-up adjustments to operating income included gross favorable adjustments of $85.8 million and gross unfavorable adjustments of $66.2 million. Gross margins for fiscal 2017 included net favorable cumulative catch-up adjustments of $57.2 million, of which $131.4 million was related to the reduction of the previously recorded forward losses on the 747-8 program, partially offset by the correction of an immaterial error of $12.7 million.
Segment operating income decreased by $455.8426.2 million, or 14.5%255.8%, to an operating loss of $3.6 billion259.6 million for the fiscal year ended March 31, 20162018, from $3.1 billion166.6 million of operating income for the fiscal year ended March 31, 2017. Organic operating income decreased $409.4 million or 275.5%. The divestitures of TAS-Newport News and Engines and APU contributed $16.7 million to the operating income decrease compared to the prior fiscal year. Organic operating income decreased for the fiscal year ended March 31, 2018, due to the decline in organic gross margin noted above and the previously mentioned goodwill impairment charge of $535.2 million.
Corporate operations incurred expenses of $102.9 million for the fiscal year ended March 31, 20152018, as compared to $109.7 million for the fiscal year ended March 31, 2017. The corporate expenses included decreased consulting expense of $5.2 million, IT services of $3.1 million, restructuring of $3.0 million, offset by increased loss on divestitures of $11.6 million.
Interest expense and other increased by $18.9 million, or 23.5%, to $99.4 million for the fiscal year ended March 31, 2018, compared to $80.5 million, due to higher interest rates, the impairment of deferred financing fees due to the amendment to the Credit Facility and the extinguishment of the Term Loan of approximately $5.2 million and the unfavorable net change in foreign exchange rate gain/loss of approximately $7.6 million compared to the prior year period.
The income tax benefit was $36.5 million for the fiscal year ended March 31, 2018, reflecting an effective tax rate of 7.9%. The rate reflects an adjustment associated with the impairment charge recognized related to Aerospace Structures which was not deductible for tax purposes. During the fiscal year ended March 31, 2018, the Company increased the valuation allowance against certain of its net deferred tax assets resulting in additional taxes of $15.6 million. The increase resulted from the net deferred tax assets generated from the current year temporary differences, the Tax Cuts and Job Act, and increase valuation allowance on certain foreign deferred tax assets.


As of March 31, 2018, we have a valuation allowance against substantially all of our net deferred tax assets given the insufficient positive evidence to support the realization of our deferred tax assets.  We intend to continue maintaining a valuation allowance on our deferred tax assets until there is sufficient positive evidence to support the reversal of all or some portion of these allowances.  A reduction in the valuation allowance could result in a significant decrease in income tax expense in the period that the release is recorded.  However, the exact timing and amount of the reduction in our valuation allowance are unknown at this time and will be subject to the earnings level we achieve as well as our projected income in future periods.

Net sales decreased by $353.3 million, or 9.1%, to $3.5 billion for the fiscal year ended March 31, 2017, from $3.9 billion for the fiscal year ended March 31, 2016. Organic sales adjusted for inter-segment sales decreased $359.9 million, or 8.9%. The acquisition of Fairchild offset by the divestitures of TAS-Newport News and Engines and APU contributed $6.6 million to net sales. Organic sales decreased due to production rate reductions by our customers on the 747-8, Gulfstream G450/G550, C-17 and A330 programs.
Cost of sales decreased by $907.5 million, or 25.2%, to $2.7 billion or the fiscal 2015 acquisitions contributed $274.5 million. The organicyear ended March 31, 2017, from $3.6 billion for the fiscal year ended March 31, 2016. Organic cost of sales includeddecreased $916.6 million or 25.0%. The acquisition of Fairchild offset by the divestitures of TAS-Newport News and Engines and APU contributed $9.1 million to cost of sales. Organic gross margin for the fiscal year ended March 31, 2017, was 23.0% compared with 6.5% for the fiscal year ended March 31, 2016. The gross margin for the fiscal year ended March 31, 2017, increased in part due to the aforementioned settlement with Boeing, compared to the prior year which was impacted by provisions for forward losses of $561.2 million on the Bombardier and 747-8 programs (as discussed above). Organic gross margin for the fiscal year ended March 31, 2016, was 3.9% compared with 19.1% for the fiscal year ended March 31, 2015. The prior year was impacted by additional costs on the 747-8 program and disruption and accelerated depreciation associated with the relocation from our Jefferson Street Facilities.programs.
Gross margin included net unfavorablefavorable cumulative catch-up adjustments on long-term contracts and provisions for forward losses as noted above ($596.2 million)($57.2 million). The unfavorablefavorable cumulative catch-up adjustments to operating income included gross

favorable adjustments of $33.0$163.3 million and gross unfavorable adjustments of $629.2$106.1 million,, of which $131.4 million was related to the reduction of the previously recorded forward losses associated with the 747-8 program and partially offset by the correction of an immaterial error in the amount of $12.7 million. Gross margins for fiscal 2016 included net unfavorable cumulative catch-up adjustments of $596.2 million, of which $561.2 million was related to provisions for forward losses associated withon the Bombardier and 747-8 programs. Excluding the aforementioned forward losses, the cumulative catch-up adjustments
Segment operating income (loss) increased by $1.2 billion, or 116.1%, to $166.6 million of operating income for the fiscal year ended March 31, 2016, reflected increased labor and supplier costs on other programs. Gross margins for fiscal 2015 included net unfavorable cumulative catch-up adjustments of $156.0 million, of which $152.0 million was related to the forward losses on the 747-8 program.
Segment2017, from a $1.0 billion operating (loss) income decreased by $1,386.2 million, or (392.7)%, to $(1,033.3) millionloss for the fiscal year ended March 31, 2016, from $353.02016. Organic operating income increased $1.18 billion million or 114.8%. The acquisition of Fairchild offset by the divestitures of TAS-Newport News and Engines and APU contributed $18.5 million to operating income. The organic operating income increased for the fiscal year ended March 31, 2015. The decreased operating income is directly related to2017 since the comparative prior year included the provisions for forward losses and gross margin changes noted above and the previously mentioned goodwill and tradename impairment charges.
Corporate operations incurred expenses of $57.8 million for the fiscal year ended March 31, 2016, as opposed to income of $81.7 million for the fiscal year ended March 31, 2015. The fiscal year ended March 31, 2015, included the legal settlement between the Company and Eaton, which resulted in a net gain of $134.7 million.
Interest expense and other decreased by $17.3 million, or 20.3%, to $68.0 million for the fiscal year ended March 31, 2016 compared to $85.4 million for the prior year. Interest expense and other for the fiscal year ended March 31, 2016, included foreign exchange losses of $2.4 million versus foreign exchange gains of $5.0$109.7 million for the fiscal year ended March 31, 2015. Interest expense and other2017, as compared to $57.8 million for the fiscal year ended March 31, 2015 included2016. The increase in corporate expenses of $54.8 million or 99.6%, was due to the redemptionrestructuring charges of $22.2 million and loss on the 2018 Notes, which included $22.6divestitures of $19.1 million.
Interest expense and other increased by $12.5 million, for pre-tax losses associated with the 4.79% redemption premium, and write-off of the remaining related unamortized discount and deferred financing fees.
The effective income tax rate was 9.6%or 18.3%, to $80.5 million for the fiscal year ended March 31, 2017, compared to $68.0 million for the prior year due to increased average debt levels and higher interest rates.
The income tax expense was $19.3 million for the fiscal year ended March 31, 2017, reflecting an effective tax rate of (81.9)%. The rate reflects an adjustment associated with the impairment charge recognized related to Aerospace Structures

which was not deductible for tax purposes. During the fiscal year ended March 31, 2017, the Company reduced the valuation allowance against certain of its net deferred tax assets resulting in a benefit of $16.0 million. The reduction resulted from the net deferred tax liabilities generated from the current year temporary differences and the utilization of deferred tax assets associated with NOL carryforwards and R&D credit carryforwards.
The income tax benefit for the fiscal year ended March 31, 2016, was $111.2 million and reflected the establishment of a valuation allowance of $155.8 million against net deferred tax assets. Based on an evaluation of both the positive and negative evidence available, we determined that it was necessary to establish a valuation allowance against substantially all of our net deferred tax assets for the fiscal year ended March 31, 2016.
A valuation allowance, if needed, reduces deferred tax assets to the amount expected to be realized. When determining the amount of net deferred tax assets that are more likely than not to be realized, the Company assesses all available positive and negative evidence. This evidence includes, but is not limited to, prior earnings history, expected future earnings, carry-back and carry-forward periods and the feasibility of ongoing tax strategies that could potentially enhance the likelihood of the realization of a deferred tax asset. The weight given to the positive and negative evidence is commensurate with the extent the evidence may be objectively verified. As such, it is generally difficult for positive evidence regarding projected future taxable income exclusive of reversing taxable temporary differences to outweigh objective negative evidence of recent financial reporting losses.
Based on these criteria and the relative weighting of both the positive and negative evidence available, and in particular the activity surrounding the Company's prior earnings history, including the forward losses and intangible impairments previously recognized, management determined that it was necessary to establish a valuation allowance against principally all of its net deferred tax assets at March 31, 2016. Given the objectively verifiable negative evidence of a three-year cumulative loss and the weighting of all available positive evidence, the Company excluded projected taxable income (aside from reversing taxable temporary differences) from the assessment of income that could be used as a source of taxable income to realize the deferred tax assets.
The effective tax rate for the fiscal year ended March 31, 2015, was 31.7% and included the release of previously reserved for unrecognized tax benefits of $1.1 million, the benefit of $2.8 million from a decrease of the state deferred tax rate and the benefit of $6.0 million from the retroactive reinstatement of the R&D tax credit to January 1, 2014.

Net sales increased by $125.5 million, or 3.3%, to $3.9 billion for the fiscal year ended March 31, 2015, from $3.8 billion for the fiscal year ended March 31, 2014. The fiscal 2015 and fiscal 2014 acquisitions, net of prior year divestitures, contributed $306.1 million. Organic sales decreased $180.6 million, or 4.6%, due to production rate cuts by our customers on the 747-8, V-22, G450/G550 and C-17 programs. The prior fiscal year was negatively impacted by our customers' decreased production rates on existing programs and decreased military sales.
Cost of sales increased by $229.7 million, or 7.9%, to $3.1 billion for the fiscal year ended March 31, 2015, from $2.9 billion for the fiscal year ended March 31, 2014. The fiscal 2015 and fiscal 2014 acquisitions, net of prior year divestitures, contributed $264.2 million. Despite the decrease in organic cost of sales, the organic cost of sales included a provision for forward losses of $152.0 million on the 747-8 program in addition to losses as a result of losing NADCAP certification at one of our facilities. Organic gross margin for the fiscal year ended March 31, 2015, was 20.1% compared with 23.1% for the fiscal year ended March 31, 2014. The prior year was impacted by additional programs costs on the 747-8 program and disruption and accelerated depreciation associated with the relocation from our Jefferson Street facilities. Excluding these charges, the comparable gross margin would have been 25.4% and 26.5%, respectively.
Gross margin included net unfavorable cumulative catch-up adjustments on long-term contracts and a provision for forward losses as noted above ($156.0 million). The unfavorable cumulative catch-up adjustments to operating income included gross favorable adjustments of $4.7 million and gross unfavorable adjustments of $160.7 million, of which $152.0 million was related to forward losses associated with the 747-8 program. The cumulative catch-up adjustments for the fiscal year ended March 31, 2015, were due primarily to labor cost growth, partially offset by other minor improvements. Gross margins for fiscal 2014 included net unfavorable cumulative catch-up adjustments of $53.2 million, which $29.8 million was related to the additional 747-8 program costs from reductions to profitability estimates on the 747-8 production lots that were completed during fiscal 2014 and $15.6 million of disruption and accelerated depreciation costs related to our exit from the Jefferson Street facilities which reduced profitability estimates on production lots completed during fiscal 2014. These decreases were partially offset by lower pension and other postretirement benefit expense of $12.7 million.
Segment operating income decreased by $87.7 million, or 19.9%, to $353.0 million for the fiscal year ended March 31, 2015 from $440.6 million for the fiscal year ended March 31, 2014. The organic operating income decreased $100.9 million, or 22.6%, and was a result of the decreased organic sales, the provision for forward losses and gross margin changes noted above, partially offset by decreased moving costs related to the relocation from our Jefferson Street facilities ($28.1 million), and legal fees ($4.5 million).
Corporate operations yielded income of $81.7 million for the fiscal year ended March 31, 2015, as opposed to expenses of $40.6 million for the fiscal year ended March 31, 2014. This result is due to the legal settlement between the Company and Eaton, which created a net gain of $134.7 million, partially offset by increased due diligence and acquisition related expenses ($9.8 million).
Interest expense and other decreased by $2.4 million, or 2.7%, to $85.4 million for the fiscal year ended March 31, 2015 compared to $87.8 million for the prior year. Interest expense and other for the fiscal year ended March 31, 2015 decreased due to lower average debt outstanding during the period as compared to the fiscal year ended March 31, 2014. Interest expense and other for the fiscal year ended March 31, 2015, included the redemption of the 2018 Notes, which included $22.6 million for pre-tax losses associated with the 4.79% redemption premium, and write-off of the remaining related unamortized discount and deferred financing fees. The fiscal year ended March 31, 2014, included the redemption of the 2017 Notes, which included

$11.0 million of pre-tax losses associated with the 4% redemption premium, and the write-off of the remaining related unamortized discount and deferred financing fees.
The effective income tax rate was 31.7% for the fiscal year ended March 31, 2015, and 33.9% for the fiscal year ended March 31, 2014. The income tax provision for the fiscal year ended March 31, 2015, was reduced to reflect the release of previously reserved for unrecognized tax benefits of $1.1 million, the benefit of $2.8 million from a decrease of the state deferred tax rate and the benefit of $6.0 million from the retroactive reinstatement of the R&D tax credit to January 1, 2014. For the fiscal year ended March 31, 2014, the income tax provision was reduced to reflect the release of previously reserved for unrecognized tax benefits of $0.7 million and additional research and development tax credit carryforward and NOL carryforward of $2.3 million.
In January 2014, the Company sold all of its shares of Triumph Aerospace Systems-Wichita, Inc. for total cash proceeds of $23.0 million, which resulted in no gain or loss from the sale.
In April 2013, the Company sold the assets and liabilities of Triumph Instruments-Burbank and Triumph Instruments-Ft. Lauderdale for total proceeds of $11.2 million, resulting in a loss of $1.5 million.
The Company expects to have significant continuing involvement in the businesses and markets of the disposed entities and therefore the disposal groups did not meet the criteria to be classified as discontinued operations.

The increase in gross margin was impacted by the increase in efficiencies in production associated with the higher volume of work.
Aftermarket Services segment operating income increased by $5.7 million, or 13.4%, to $47.9 million for the fiscal year ended March 31, 2015, from $42.3 million for the fiscal year ended March 31, 2014. Operating income increased primarily2016, due to the increased sales and changes to gross margin noted above and the acquisition of NAAS net of the previously divested Triumph Instruments companies ($1.6 million). Theseabove. The same factors contributed to the increase in Adjusted EBITDA margin year over year.
Aftermarket Services segment operating income as a percentage of segment sales increased to 15.8% for the fiscal year ended March 31, 2015, as compared with 14.7% for the fiscal year ended March 31, 2014, due to the improved gross margin noted above.



Liquidity and Capital Resources
Our working capital needs are generally funded through cash flow from operations and borrowings under our credit arrangements. During the year ended March 31, 2016,2018, we generatedused approximately $83.9$288.9 million of cash flow from operating activities, usedreceived approximately $128.0$38.2 million infrom investing activities and received approximately $32.5$213.6 million in financing activities. In fiscal 2015, cash flows from operating activities included pension contributions of $112.3 million.
For the fiscal year ended March 31, 2016,2018, we had a net cash inflowoutflow of $83.9$288.9 million from operating activities, aan decrease of $383.5$570.4 million, compared to a net cash inflow of $467.3$281.5 million for the fiscal year ended March 31, 2015.2017. During fiscal 2016,2018, the net cash provided byused in operating activities was primarily attributable to decreased receipts from customers ($873.1 million), offset by the timing of payments on accounts payable and other accrued expenses ($251.5 million) driven by decreased pre-production costs, and net spending on the TulsaG280 and G650 Programs discussed below, offset by increased receipts from customers and others related to increased collection efforts ($40.9407.2 million). During fiscal 2015, the net increase in cash provided by operating activities was primarily due to the cash received from a legal settlement ($134.7 million), and an income tax refund ($26.0 million).

We continue to invest in inventory for new programs which impacts our cash flows from operating activities. During fiscal 20162018 expenditures for inventory costs on new programs, excluding progress payments, including the Bombardier Global 7000/8000 and the Embraer E-Jet programs, were $146.1$384.9 million and $83.8$35.1 million, respectively. Net spend on the Tulsa Programs during fiscal 2016 was approximately $57.3 million. Additionally, inventory for mature programs declined due to decreased production rates and the utilization of build ahead inventory, by approximately $67.8$144.4 million. Unliquidated progress payments netted against inventory decreased $66.8increased $162.5 million due to timing of receipts.receipts and resolution of open assertions.
Cash flows provided by investing activities for the fiscal year ended March 31, 2018, increased $3.9 million from the fiscal year ended March 31, 2017. Cash flows provided by investing activities for the fiscal year ended March 31, 2018 included cash from the divestitures of TS-LI and Embee of $83.1 million offset by capital expenditures of $42.1 million.

Cash flows provided by financing activities for the fiscal year ended March 31, 2016,2018, were $32.5$213.6 million, compared to cash flows used in financing activities for the fiscal year ended March 31, 2015,2017, of $395.2$266.5 million. Cash flows provided by financing activities for the fiscal year ended March 31, 2016,2018 included the issuance of our Senior Notes due 2025 of $500.0 million, offset by repayment of the 2013 Term Loan of $302.3 million, payment of financing fees $17.7 million and additional borrowings on our Credit Facility (as defined below) to fund the acquisition of Fairchild and to fund operations. Cash flows used in financing activities for the fiscal year ended March 31, 2015, included the redemption of the 2018 Notes, settlement of the Convertible Senior Subordinated Notes ("Convertible Notes") redemptions and the purchase of our common stock ($184.4 million), offset by the issuance of the 2022 Notes..
As of March 31, 2016, $834.32018, $656.5 million was available under the Company's existing credit agreement ("Credit Facility").  On March 31, 2016,2018, an aggregate amount of approximately $140.0$112.9 million in outstanding borrowingborrowings and approximately $25.7$30.6 million in letters of credit were outstanding under the Credit Facility, all of which were accruing interest at LIBOR plus applicable basis points totaling 2.00% per annum. Amounts repaid under the Credit Facility may be reborrowed.
In July 2017, the Company entered into a Ninth Amendment to the Credit Agreement (the “Ninth Amendment” and the Existing Credit Agreement as amended by the Ninth Amendment, the “Credit Agreement”) with the Administrative Agent and the Lenders party thereto to, among other things, (i) permit the Company to incur High Yield Indebtedness (as defined in the Credit Agreement) in an aggregate principal amount of up to $500.0 million, subject to the Company’s obligations to apply the net proceeds from this offering to repay the outstanding principal amount of the term loans in full, (ii) limit the mandatory prepayment provisions to eliminate the requirement that net proceeds received from the incurrence of Permitted Indebtedness (as defined in the Credit Agreement), including the High Yield Indebtedness, be applied to reduce the revolving credit commitments once the revolving credit commitments have been reduced to $800.0 million, (iii) amend certain covenants and other terms and (iv) modify the current interest rate and letter of credit pricing tiers.
In connection with the amendment to the Credit Agreement, the Company incurred $0.6 million of financing costs. These costs, along with the $13.2 million of unamortized financing costs subsequent to the amendment, are being amortized over the remaining term of the Credit Agreement. In accordance with the reduction in the capacity of the Credit Agreement, the Company wrote-off a proportional amount of unamortized financing fees prior to the amendment.
In May 2017, the Company entered into an Eighth Amendment to the Third Amended and Restated Credit Agreement, among the Company and its lenders to, among other things, (i) eliminate the total leverage ratio financial covenant, (ii) increase the maximum permitted senior secured leverage ratio financial covenant applicable to each fiscal quarter, commencing with the fiscal quarter ended March 31, 2017, and to revise the step-downs applicable to such financial covenant, (iii) reduce the aggregate principal amount of commitments under the revolving line of credit to $850.0 million from $1,000.0 million, (iv) modify the maturity date of the term loans so that all of the term loans will mature on March 31, 2019, and (v) establish a new higher pricing tier for the interest rate, commitment fee and letter of credit fee pricing provisions.

On March 28, 2016, wethe Company entered into a Purchase Agreement ("Receivables Purchase Agreement") to sell certain accounts receivables to a financial institution without recourse. We areThe Company was the servicer of the accounts receivable under the Receivables Purchase Agreement. As of March 31, 2016, the maximum amount available under the Receivables Purchase Agreement was $90.0 million. Interest rates are based on LIBOR plus 0.65% -0.70%- 0.70%. As of March 31, 2016, we2017, the Company sold $89.9$78.0 million, worth of eligible accounts receivable. The Company currently has no capacity under the Receivables Purchase Agreement to sell Accounts Receivable.
In November 2014, the Company amended its receivable securitization facility (the “Securitization Facility”), increasing the purchase limit from $175.0 million to $225.0 million and extending the term through November 2017.
In May 2014, the Company amended its existing Credit Facility with its lenders to (i) to increase the maximum amount allowed for the Securitization Facility and (ii) amend certain other terms and covenants.
In November 2013, the Company amended the Credit Facility with its lenders to (i) provide for a $375.0 million Term Loan with a maturity date of May 14, 2019, (ii) maintain a Revolving Line of Credit under the Credit Facility to $1,000.0 million$0.8 billion and increase the accordion feature to $250.0 million, and (iii) amend certain other terms and covenants. The amendment resulted in a more favorable pricing grid and a more streamlined package of covenants and restrictions.
The level of unused borrowing capacity under the Company's Revolving Credit Facility varies from time to time depending in part upon its compliance with financial and other covenants set forth in the related agreement. The Credit Facility contains certain affirmative and negative covenants, including limitations on specified levels of indebtedness to earnings before interest, taxes, depreciation and amortization, and interest coverage requirements, and includes limitations on, among other things, liens, mergers, consolidations, sales of assets, payment of dividends and incurrence of debt. As of March 31, 2016,2018, the Company was in compliance with all such covenants.
In August 2017, the Company issued $500.0 million principal amount of 7.750% Senior Notes due 2025 (the "2025 Notes"). The 2025 Notes were sold at 100% of principal amount and have an effective interest yield of 7.750%. Interest on the 2025 Notes accrues at the rate of 7.750% per annum and is payable semiannually in cash in arrears on February 15 and August 15 of each year, commencing on February 15, 2018. We used the net proceeds to payoff the Term Loan and to reduce the outstanding balance of the Revolver. In connection with the issuance of the 2025 Notes, the Company incurred approximately $8.8 million of costs, which were deferred and are being amortized on the effective interest method over the term of the 2025 Notes.
In June 2014, the Company issued the 2022 Notes for $300.0 million in principal amount. The 2022 Notes were sold at 100% of principal amount and have an effective yield of 5.25%. Interest on the 2022 Notes is payable semiannually in cash in arrears on June 1 and December 1 of each year. We used the net proceeds to redeem the 2018 Notes and pay related fees and expenses. In connection with the issuance of the 2022 Notes, the Company incurred approximately $5.0 million of costs, which were deferred and are being amortized on the effective interest method over the term of the notes.
In February 2013, the Company issued the 2021 Notes for $375.0 million in principal amount. The 2021 Notes were sold at 100% of principal amount and have an effective interest yield of 4.875%. Interest on the 2021 Notes is payable semiannually in cash in arrears on April 1 and October 1 of each year. We used the net proceeds to repay borrowings under our

Credit Facility and pay related fees and expenses, and for general corporate purposes. In connection with the issuance of the 2021 Notes, the Company incurred approximately $6.3 million of costs, which were deferred and are being amortized on the effective interest method over the term of the notes.

For the fiscal year ended March 31, 2015,2017, we had a net cash inflow of $467.3$281.5 million from operating activities, an inflow increase of $332.2$197.7 million, compared to a net cash inflow of $135.1$83.9 million for the fiscal year ended March 31, 2014.2016. During fiscal 2015,2017, the increase in net cash provided by operating activities was primarily dueattributable to the cash received from legal settlement ($134.7 million), increased receipts from customers and others relating to additional sales from fiscal 2015 and fiscal 2014 acquisitions ($110.4440.6 million), an income tax refund ($26.0 million), and decreased disbursements to employees, suppliers and others ($114.9 million) due to timing, offset by increased pension contributionsthe timing of payments on accounts payable and other accrued expenses driven by pre-production costs, net spending on the G280 and G650 Programs ($66.0286.2 million). and a $5.5 million payment related to a previously resolved legal settlement.
We investedcontinue to invest in inventory for new programs and additional production costs for ramp-up activities in support of increasing build rates on several programs and build ahead for the relocationwhich impacts our cash flows from our largest facilities.operating activities. During fiscal 2015,2017 expenditures for inventory build for capitalized pre-production costs on new programs, excluding progress payments, including the Bombardier Global 7000/8000 and the Embraer E-Jet programs, were $127.0$183.3 million and $48.7$26.4 million, respectively. Offsetting this inventory build was a provision for forward losses on our long-term contractNet spend on the 747-8 program of $152.0Tulsa Programs during fiscal 2017 was approximately $76.5 million. Additionally, inventory for mature programs declined due to decreased production rates, by approximately $82.9 million. Unliquidated progress payments netted against inventory increased $24.9$99.3 million due to timing of receipts. Capitalized pre-production costs are expected to continue to increase, while our production is expected to remain consistent over

Cash flows provided by investing activities for the next few quarters.
fiscal year ended March 31, 2017 increased $162.4 million from the fiscal year ended March 31, 2016. Cash flows provided by investing activities for the fiscal year ended March 31, 2017 included cash from the divestitures of TAS - Newport News and Engines and APU ($86.2 million) offset by capital expenditures ($51.8 million). Cash flows used in investing activities for the fiscal year ended March 31, 2015, decreased by $178.8 million from the fiscal year ended March 31, 2014. Cash flows2016 included cash used in investing activities included the cash received fromto fund the acquisition of Tulsa ProgramsFairchild ($160.057.1 million) offset by, and a payment to settle a working capital adjustment related to the acquisitionsacquisition of GE ($65.06.0 million) and NAAS ($43.7 million) and the working capital finalization of the acquisition of Primus ($13.0 million). The fiscal year ended March 31, 2014, included the fiscal 2014 acquisitions of $94.5 million and capital expenditures of $86.6 million associated with our new facilities in Red Oak, Texas.($80.0 million).
Cash flows used in financing activities for the fiscal year ended March 31, 2015,2017 were $395.2$266.5 million, compared to cash flows provided by financing activities for the fiscal year ended March 31, 2014,2016 of $103.2$32.5 million. Cash flows used in financing activities for the fiscal year ended March 31, 2015,2017, included the redemption of the 2018 Notes, settlement of the Convertible Senior Subordinated Notes ("Convertible Notes") redemptions and the purchase ofpayments funded by our common stock ($184.4 million), offset by the issuance of the 2022 Notes.
At March 31, 2016, $19.2 million of cash and cash equivalents were held by foreign subsidiaries and were primarily denominated in foreign currencies. If these amounts would be remitted as dividends, the Company may be subject to additional U.S. taxes, net of allowable foreign tax credits. We currently expect to utilize the balances to fund our foreign operations.
Subsequent to year end, to ensure that we had full accessoperations to our Revolving Credit Facility (the "Credit Facility") during fiscal 2017, we obtained approval from the holders of the 2021 Notes to amend the terms of the indenture to conform with the 2022 Notes which allows for a higher level of secured debt. Absent this consent, we would have been restricted as to the level of new borrowings under the Credit Facility during fiscal 2017.
Further, to mitigate the risk of failing to obtain the consent and to ensure we had adequate liquidity through fiscal 2017, we chose to make a significant draw on the Credit Facility in early April 2016, taking the outstanding balance to approximately $800,000. We paid down substantially all of the draw to the Credit Facility upon receiving consent from the holders of the 2021 Notes in May 2016.
In May 2016, the Company entered into a Sixth Amendment to the Third Amended and Restated Credit Agreement, among the Company, the Subsidiary Co-Borrowers, the lenders party thereto and the Administrative Agent (the “Sixth Amendment” and the Credit Facility, as amended by the Sixth Amendment, the “Credit Agreement”), pursuant to which those lenders electing to enter into the Sixth Amendment extended the expiration date for the revolving line of credit and the maturity date for the term loan by five years to May 3, 2021. Lenders holding revolving credit commitments aggregating $940.0 million elected to extend the expiration date for the revolving line of credit, and Lenders holding approximately $324.5 million of term loans (out of an aggregate outstanding term loan balance of approximately $330.0 million) elected to extend the term loan maturity date.
In addition, the Sixth Amendment amended the Credit Facility to, among other things, (i) modify certain financial covenants to allow for the add-back of certain cash and non-cash charges, (ii) amend the total leverage ratio financial covenant to provide for a gradual reduction in the maximum permitted total leverage ratio commencing with the fiscal year ending March 31, 2018, (iii) increase the interest rate, commitment fee and letter of credit fee pricing provisions for the highest pricing tier, (iv) establish the interest rate, commitment fee and letter of credit fee pricing at the highest pricing tier until the Company

delivers its compliance certificate for its fiscal year ending March 31, 2017, (v) increase the minimum revolver availability threshold test in connection with the Company making certain permitted investments, certain additional permitted dividends, permitted acquisitions and permitted payments of certain types of indebtedness, and (vi) decrease the maximum senior secured leverage ratio threshold test in connection with the Company making certain permitted investments, certain permitted dividends, permitted acquisitions and permitted payments of certain types of indebtedness during the period from the date of the Sixth Amendment until the Company delivers its compliance certificate for the fiscal year ending March 31, 2017.(as defined above).
Capital expenditures were $80.0$42.1 million for the fiscal year ended March 31, 2016.2018. We funded these expenditures through cash from operations and borrowings under the Credit Facility. We expect capital expenditures of approximately $80.0 million to $100.0 million and net investments in new major programs of $50.0 million to $60.0$70.0 million of which will be reflected in inventory for our fiscal year ending March 31, 2017.2018. The expenditures are expected to be used mainly to expand capacity or replace old equipment at several facilities.

Current plan documents reserve our right to amend or terminate the plans at any time, subject to applicable collective bargaining requirements for represented employees.
We believe that cash generated by operations and borrowings under the Credit Facility will be sufficient to meet anticipated cash requirements for our current operations for the foreseeable future.at least the next twelve months.
Loans under the Credit Facility bear interest, at the Company's option, by reference to a base rate or a rate based on LIBOR, in either case plus an applicable margin determined quarterly based on the Company's Total Leverage Ratio (as defined in the Credit Facility) as of the last day of each fiscal quarter. The Company is also required to pay a quarterly commitment fee on the average daily unused portion of the Credit Facility for each fiscal quarter and fees in connection with the issuance of letters of credit. All outstanding principal and interest under the Credit Facility will be due and payable on the maturity date.
The Credit Facility contains representations, warranties, events of default and covenants customary for financings of this type, including, without limitation, financial covenants under which the Company is obligated to maintain on a consolidated basis, as of the end of each fiscal quarter, a certain minimum Interest Coverage Ratio maximum Total Leverage Ratio and maximum Senior Leverage Ratio (in each case as defined in the Credit Facility).
CRITICAL ACCOUNTING POLICIES
Critical accounting policies are those accounting policies that can have a significant impact on the presentation of our financial condition and results of operations, and that require the use of complex and subjective estimates based upon past experience and management's judgment. Because of the uncertainty inherent in such estimates, actual results may differ from these estimates. Below are those policies applied in preparing our consolidated financial statements that management believes are the most dependent on the application of estimates and assumptions. For additional accounting policies, see Note 2 of "Notes to Consolidated Financial Statements."
Allowance for Doubtful Accounts
Trade receivables are presented net of an allowance for doubtful accounts. In determining the appropriate allowance, we consider a combination of factors, such as industry trends, our customers' financial strength and credit standing, and payment and default history. The calculation of the required allowance requires a judgment as to the impact of these and other factors on the ultimate realization of our trade receivables. We believe that these estimates are reasonable and historically have not resulted in material adjustments in subsequent periods when the estimates are adjusted to actual amounts.
Inventories
The Company records inventories at the lower of cost or estimated net realizable value. Costs on long-term contracts and programs in progress represent recoverable costs incurred for production or contract-specific facilities and equipment, allocable operating overhead and advances to suppliers. Pursuant to contract provisions, agencies of the U.S. Government and certain other customers have title to, or a security interest in, inventories related to such contracts as a result of advances, performance-based payments, and progress payments. The Company reflects those advances and payments as an offset against the related

inventory balances. The Company expenses general and administrative costs related to products and services provided essentially under commercial terms and conditions as incurred. The Company determines the costs of inventories by the first-in, first-out or average cost methods.
Advance payments and progress payments received on contracts-in-process are first offset against related contract costs that are included in inventory, with any remaining amount reflected in current liabilities.
Work-in-process inventory includes capitalized pre-production costs. Company policy allows for the capitalization of pre-production costs after it establishes a contractual arrangement with a customer that explicitly states that the cost of recovery of pre-production costs is allowed.
Capitalized pre-production costs include nonrecurring engineering, planning and design, including applicable overhead, incurred before production is manufactured on a regular basis. Significant customer-directed work changes can also cause pre-production costs to be incurred (see Note 5 of "Notes to Consolidated Financial Statements" for further discussion).
Revenue and Profit Recognition
Revenues are recognized in accordance with the contract terms when products are shipped, delivery has occurred or services have been rendered, pricing is fixed or determinable, and collection is reasonably assured.
A significant portion of our contracts are within the scope of Accounting Standards Codification ("ASC") 605-35, Revenue Recognition —Construction-Type and Production-Type Contracts, and revenue and costs on contracts are recognized using the percentage-of-completion method of accounting. Accounting for the revenue and profit on a contract requires estimates of (1) the contract value or total contract revenue, (2) the total costs at completion, which is equal to the sum of the actual incurred costs to date on the contract and the estimated costs to complete the contract's scope of work and (3) the measurement of progress towardstoward completion. Depending on the contract, we measure progress toward completion using either the cost-to-cost method or the units-of-delivery method, with the great majority measured under the units-of-delivery method.
Under the cost-to-cost method, progress toward completion is measured as the ratio of total costs incurred to our estimate of total costs at completion. We recognize costs as incurred. Profit is determined based on our estimated profit margin on the contract multiplied by our progress toward completion. Revenue represents the sum of our costs and profit on the contract for the period.
Under the units-of-delivery method, revenue on a contract is recorded as the units are delivered and accepted during the period at an amount equal to the contractual selling price of those units. The costs recorded on a contract under the units-of-delivery method are equal to the total costs at completion divided by the total units to be delivered. As our contracts can span multiple years, we often segment the contracts into production lots for the purposes of accumulating and allocating cost. Profit is recognized as the difference between revenue for the units delivered and the estimated costs for the units delivered.
Adjustments to original estimates for a contract's revenues, estimated costs at completion and estimated total profit are often required as work progresses under a contract, as experience is gained and as more information is obtained, even though the scope of work required under the contract may not change, or if contract modifications occur. These estimates are also sensitive to the assumed rate of production. Generally, the longer it takes to complete the contract quantity, the more relative overhead that contract will absorb. The impact of revisions in cost estimates is recognized on a cumulative catch-up basis in the period in which the revisions are made. Provisions for anticipated losses on contracts are recorded in the period in which they become evident ("forward losses") and are first offset against costs that are included in inventory, with any remaining amount reflected in accrued contract liabilities in accordance with ASC 605-35. Revisions in contract estimates, if significant, can materially affect our results of operations and cash flows, as well as our valuation of inventory. Furthermore, certain contracts are combined or segmented for revenue recognition in accordance with ASC 605-35.
For the fiscal year ended March 31, 20162018, cumulative catch-up adjustments resulting from changes in contract values and estimated costs that arose during the fiscal year decreasedincreased operating (loss) income,loss, net (loss) incomeloss and earnings per share by approximately $(596.2)19.7 million, $(539.0)13.5 million and $(10.95)0.27, respectively. The cumulative catch-up adjustments to operating income for the fiscal year ended March 31, 20162018, included gross favorable adjustments of approximately $33.085.8 million and gross unfavorable adjustments of approximately $629.2 million, which includes provisions of $561.2 million for forward losses on the Bombardier and 747-8 programs.$66.2 million.
For the fiscal year ended March 31, 20152017, cumulative catch-up adjustments resulting from changes in estimates increased operating loss, net loss and earnings per share by approximately $57.2 million, $52.6 million and $1.07, respectively. The cumulative catch-up adjustments to operating income for the fiscal year ended March 31, 2017, included gross favorable adjustments of approximately $163.3 million and gross unfavorable adjustments of approximately $106.1 million, which includes a reduction to the previously recognized forward losses of $131.4 million for the 747-8 program.

For the fiscal year ended March 31, 2016, cumulative catch-up adjustments resulting from changes in estimates decreased operating income, net income and earnings per share by approximately $(156.0)$596.2 million,, $(106.6) $539.0 million and $(2.09),$10.95, respectively. The cumulative catch-up adjustments to operating income for the fiscal year ended March 31, 2015,2016, included

gross favorable adjustments of approximately $4.7$33.0 million and gross unfavorable adjustments of approximately $160.7$629.2 million which includes a provision of $152.0 million for forward losses of $561.2 million on the Bombardier Global 7000/8000 ("Bombardier") and 747-8 program.
For the fiscal year ended March 31, 2014, cumulative catch-up adjustments resulting from changes in estimates decreased operating income, net income and earnings per share by approximately $(53.2) million, $(35.1) million and $(0.67), respectively. The cumulative catch-up adjustments to operating income for the fiscal year ended March 31, 2014, included gross favorable adjustments of approximately $14.3 million and gross unfavorable adjustments of approximately $67.5 million.programs.
Amounts representing contract change orders or claims are only included in revenue when such change orders or claims have been settled with our customer and to the extent that units have been delivered. Additionally, some contracts may contain provisions for revenue sharing, price re-determination, requests for equitable adjustments, change orders or cost and/or performance incentives. Such amounts or incentives are included in contract value when the amounts can be reliably estimated and their realization is reasonably assured.
Although fixed-price contracts, which extend several years into the future, generally permit us to keep unexpected profits if costs are less than projected, we also bear the risk that increased or unexpected costs may reduce our profit or cause the Company to sustain losses on the contract. In a fixed-price contract, we must fully absorb cost overruns, notwithstanding the difficulty of estimating all of the costs we will incur in performing these contracts and in projecting the ultimate level of revenue that may otherwise be achieved.
As previously disclosed, we recognized a provision for forward losses associated with our long-term contract on the 747-8 and Bombardier programs. There is still risk similar to what we have experienced on the 747-8 and Bombardier programs. Particularly, our ability to manage risks related to supplier performance, execution of cost reduction strategies, hiring and retaining skilled production and management personnel, quality and manufacturing execution, program schedule delays and many other risks, will determine the ultimate performance of these long-term programs.
The Aftermarket Services Group provides repair and overhaul services, certain of which are provided under long-term power-by-the-hour contracts, comprising approximately 6% of the segment's fiscal 2016 net sales. The Company applies the proportional performance method to recognize revenue under these contracts. Revenue is recognized over the contract period as units are delivered based on the relative value in proportion to the total estimated contract consideration. In estimating the total contract consideration, management evaluates the projected utilization of its customer's fleet over the term of the contract, in connection with the related estimated repair and overhaul servicing requirements to the fleet based on such utilization. Changes in utilization of the fleet by customers, among other factors, may have an impact on these estimates and require adjustments to estimates of revenue to be realized.
Goodwill and Intangible Assets
The Company accounts for purchased goodwill and intangible assets in accordance with Accounting Standards Codification ("ASC") 350, Intangibles—Goodwill and Other. Under ASC 350, purchased goodwill and intangible assets with indefinite lives are not amortized; rather, they are tested for impairment on at least an annual basis. Additionally, intangibleIntangible assets with finite lives continue to beare amortized over their useful lives. Upon acquisition, critical estimates are made in valuing acquired intangible assets, which include but are not limited to: future expected cash flows from customer contracts, customer lists, and estimating cash flows from projects when completed; tradename and market position, as well as assumptions about the period of time that customer relationships will continue; and discount rates. Management's estimates of fair value are based upon assumptions believed to be reasonable, but which are inherently uncertain and unpredictable and, as a result, actual results may differ from the assumptions used in determining the fair values.
The Company's operating segments of Aerostructures,Integrated Systems, Aerospace SystemsStructures and Aftermarket ServicesProduct Support are also its reporting units under ASC 350, Intangibles—Goodwill and Other.units. The Chief Executive Officer is the Company's CODM.Chief Operating Decision Maker ("CODM"). The Company's CODM evaluates performance and allocates resources based upon review of segment information. Each of the operating segments is comprisedcomposed of a number of operating units which are considered to be components under ASC 350.components. The components, for which discrete financial information exists, are aggregated for purposes of goodwill impairment testing.testing into three reporting units. The Company's acquisition strategy is to acquire companies that complement and enhance the capabilities of the operating segments of the Company. Each acquisition is assigned to either the AerostructuresIntegrated Systems reporting unit, the Aerospace SystemsStructures reporting unit or the Aftermarket ServicesProduct Support reporting unit. The goodwill that results from each acquisition is also assigned to the reporting unit to which the acquisition is allocated, because it is that reporting unit which is intended to benefit from the synergies of the acquisition.
The Company assesses whether goodwill impairment exists using both the qualitative and quantitative assessments. The qualitative assessment involves determining whether events or circumstances exist that indicate it is more likely than not that the fair value of a reporting unit is less than its carrying amount, including goodwill. If based on this qualitative assessment the Company determines it is not more likely than not that the fair value of a reporting unit is less than its carrying amount or if

the Company elects not to perform a qualitative assessment, a quantitative assessment is performed as required by ASC 350 to determine whether a goodwill impairment exists at the reporting unit.
The quantitative test is used to compare the carrying amount of the reporting unit's assets to the fair value of the reporting unit. If the fair value exceeds the carrying value, no further evaluation is required and no impairment loss is recognized. If the carrying amount exceeds the fair value, then an impairment loss occurs. The impairment is measured by using the amount by which the carrying value exceeds the fair value not to exceed the amount of recorded goodwill. The determination of the fair value of our reporting units is based, among other things, on estimates of future operating performance of the reporting unit

being valued. We are required to complete an impairment test for goodwill and record any resulting impairment losses at least annually. Changes in market conditions, among other factors, may have an impact on these estimates and require interim impairment assessments.
When performing the quantitative impairment test, the Company's methodology includes the use of an income approach which discounts future net cash flows to their present value at a rate that reflects the Company's cost of capital, otherwise known as the discounted cash flow method ("DCF"). These estimated fair values are based on estimates of future cash flows of the businesses. Factors affecting these future cash flows include the continued market acceptance of the products and services offered by the businesses, the development of new products and services by the businesses and the underlying cost of development, the future cost structure of the businesses, and future technological changes. The Company also incorporates market multiples for comparable companies in determining the fair value of our reporting units. Any such impairment would be recognized in full in the reporting period in which it has been identified. The Company early adopted Accounting Standards Update ("ASU") 2017-04, which eliminates Step 2 of the goodwill impairment analysis (see Recently Issued Accounting Pronouncements below).
Consistent with the Company's policy described here, the Company performs an annual assessment in its fiscal fourth quarter and on an interim basis upon the occurrence of events or substantive changes in circumstances that indicate a reporting unit's carrying value may be less than its fair value. The Company performed an interim assessment of the fair value of its goodwill due to the Company's decision to combine the Aerospace Structures and Precision Components reporting segments into one reporting segment as noted above. In accordance with ASC 350-20-35-3C, there are several potential events and circumstances that could be indicators of goodwill impairment. A change in a company's reporting unit structure is one of these events, and when this does occur, a company must perform a "before and after" test of the reporting units (see Note 1). Additionally, the Company's enhanced visibility into its future cash flows based on its annual planning process was also an indicator. Consistent with the Company's policy, it performed the goodwill impairment test which includes using a combination of both the market and income approaches to estimate the fair value of each reporting unit.
After performing the "before" portion of the test of the reporting units, the Company concluded that the former Precision Components' reporting unit had a fair value that was lower than its carrying value by an amount of $190.2 million. Accordingly, the Company recorded a non-cash impairment charge during the fiscal quarter ended December 31, 2017 of $190.2 million, which is presented on the accompanying Consolidated Statements of Operations as "Impairment of intangible assets”. The decline in fair value is the result of declining revenues from production rate reductions on sun-setting programs and the slower than previously projected ramp in our development programs and the timing of associated earnings and cash flows.
The Company then performed the "after" portion of the test of the reporting units and concluded that the new reporting unit of Aerospace Structures' goodwill had a fair value that was lower than its carrying value by an amount that exceeded the remaining goodwill for the reporting unit. Following the applicable accounting guidance, this impairment charge is deemed to have occurred during the Company's fiscal fourth quarter. Therefore, the Company recorded a non-cash impairment charge during the fiscal quarter ended March 31, 2018, of $345.0 million, which is presented on the Consolidated Statements of Operations as "Impairment of intangible assets” for the fiscal year ended March 31, 2018. The decline in fair value is the result of declining revenues from sustained production rate reductions and sun-setting programs and the slower than previously projected ramp in our development programs and the timing of associated earnings and cash flows (See Note 2 for definition of fair value levels). The assessment for the Company's Integrated Systems and Product Support reporting units indicated that their fair value exceeded their carrying amounts.
In the fourth quarter of the fiscal year ended March 31, 2017, consistent with the Company's policy described here within, the Company performed its annual assessment of the fair value of goodwill. The Company concluded that the goodwill related to the Aerospace Structures reporting unit was impaired as of the annual testing date. The Company concluded that the reporting unit had a fair value that was lower than its carrying value by an amount that exceed the remaining goodwill for the reporting unit. Accordingly, the Company recorded a non-cash impairment charge during the fourth quarter of the fiscal year ended March 31, 2017, of $266.3 million, which is presented on the accompanying Consolidated Statements of Operations as "Impairment of intangible assets”. The decline in fair value is the result of declining revenues from production rate reductions on sun-setting programs and the slower than previously projected ramp in our development programs and the timing of associated earnings and cash flows (see Note 2 of the Notes to Consolidated Financial Statements for definition of fair value levels).

Prior to adoption of ASU 2017-04, the Company used the quantitative assessment to perform the two-step approach required by ASC 350 to determine whether a goodwill impairment exists at the reporting unit.
The first step of the quantitative test is to compare the carrying amount of the reporting unit's assets to the fair value of the reporting unit. If the fair value exceeds the carrying value, no further work is required and no impairment loss is recognized. If the carrying amount exceeds the fair value, then the second step is required to be completed, which involves allocating the fair value of the reporting unit to each asset and liability, with the excess being applied to goodwill. An impairment loss occurs if the amount of the recorded goodwill exceeds the implied goodwill. The determination of the fair value of our reporting units is based, among other things, on estimates of future operating performance of the reporting unit being valued. We are required to complete an impairment test for goodwill and record any resulting impairment losses at least annually. Changes in market conditions, among other factors, may have an impact on these estimates and require interim impairment assessments.
When performing the two-step quantitative impairment test, the Company's methodology includes the use of an income approach which discounts future net cash flows to their present value at a rate that reflects the Company's cost of capital, otherwise known as the discounted cash flow method ("DCF"). These estimated fair values are based on estimates of future cash flows of the businesses. Factors affecting these future cash flows include the continued market acceptance of the products and services offered by the businesses, the development of new products and services by the businesses and the underlying cost of development, the future cost structure of the businesses, and future technological changes. The Company also incorporates market multiples for comparable companies in determining the fair value of our reporting units. Any such impairment would be recognized in full in the reporting period in which it has been identified.
In the fourth quarter of fiscal 2016, the Company performed the quantitative assessment in lieu of the qualitative assessment for eachall three of the Company's threeformer reporting units, which indicated that the fair value of goodwill for the Aerostructuresformer Aerospace Structures reporting unit did not exceed its carrying amount. Asamount, resulting in a result we incurred an $597.6 million impairment of goodwill to the Aerostructuresformer Aerospace Structures reporting unit. The assessment for the Company's Aerospace Systems and Aftermarket Services reporting units indicated that the fair value of their respective goodwill exceeded the carrying amount. We incurred no impairment of goodwill as a result of our annual goodwill impairment tests in fiscal 2015 or 2014 (see Note 7 of "Notes to Consolidated Financial Statements" for further discussion).
As of March 31, 2015,2018, the Company had a $438.4$150.0 million indefinite-lived intangible asset associated with the tradenames acquired in the acquisitions of Vought and Embee tradenames. TheAircraft Industries, Inc. ("Vought"). Prior to March 31, 2017, the Company assessesassessed whether indefinite-lived intangible assets impairment exists using both the qualitative and quantitative assessments. The qualitative assessment involves determining whether events or circumstances exist that indicate it is more likely than not that the fair value of an indefinite-lived intangible asset is less than its carrying amount. If based on this qualitative assessment, the Company determines it is not more likely than not that the fair value of an indefinite-lived intangible asset is less than its carrying amount or if the Company elects not to perform a qualitative assessment, a quantitative assessment is performed to determine whether an indefinite-lived intangible asset impairment exists. We test the indefinite-lived intangible assets for impairment by comparing the carrying value to the fair value based on current revenue projections of the related operations, under the relief from royalty method. Any excess carryof the carrying value over the amount of fair value is recognized as an impairment.
During the third quarter of the fiscal year ended March 31, 2016, the Company performed an interim assessment of fair value on our indefinite-lived intangible assets due to potential indicators of impairment related to the continued decline in our stock price during the fiscal third quarter. Based on the Company's evaluation, of indefinite-lived assets, including the tradenames, the Company concluded that the Vought tradename had a fair value of $195.8 million (Level 3) compared to a carrying value of $425.0 million. Accordingly, the Company recorded a non-cash impairment charge during the fiscal year ended March 31, 2016, of $229.2 million, which is presented on the accompanying Consolidated Statements of Operations as "Impairment of intangible assets".assets." The decline in fair value compared to the carrying value of the Vought tradename is the result of declining revenues from production rate reductions and the slower than previously projected ramp in Bombardier Global 7000/8000 and the timing of associated earnings.
In the fourth quarter of fiscal 2016, the Company performed its annual impairment test for each of the Company's indefinite-lived intangible assets, which indicated that the Vought and Embee tradenames had a fair value of $163.0 million (Level 3) compared to a carrying value of $209.2 million. The decline in fair value of the tradenames is the result of the increase in discount rate during the fourth quarter of fiscal 2016, which required the Company to assess whether events and/or circumstances have changed regarding the indefinite-life conclusion. As a result wethe Company incurred a non-cash impairment charge of $46.2 million presented on the accompanying Consolidated Statements of Operations as "Impairment of intangible assets" to the Vought and Embee tradenames. Additionally, it wastradenames and a reduction to indefinite-life to a useful life of 20 years.
During the fiscal year ended March 31, 2017, as part of the Company's annual assessment, the Company determined that the tradenames will be amortized over their remaining estimated useful life for the Vought tradename should be reduced from a useful life of 20 years. We incurred no impairmentyears to a useful life of indefinite-lived assets10 years, as a result of our annual indefinite-lived assets impairment tests in fiscal 2015 or 2014 (see Note 7 of "Notesit better represents the financial performance relative to Consolidated Financial Statements" for further discussion).the expected performance.

Finite-lived intangible assets are amortized over their useful lives ranging from 3 to 3230 years. WeThe Company continually evaluateevaluates whether events or circumstances have occurred that would indicate that the remaining estimated useful lives of our long-lived

assets, including intangible assets, may warrant revision or that the remaining balance may not be recoverable. Intangible assets are evaluated for indicators of impairment. When factors indicate that long-lived assets, including intangible assets, should be evaluated for possible impairment, an estimate of the related undiscounted cash flows over the remaining life of the long-lived assets, including intangible assets, is used to measure recoverability.recoverability based on the primary asset of the asset group. Some of the more important factors we considermanagement considers include ourthe Company's financial performance relative to our expected and historical performance, significant changes in the way we manage ourthe Company manages its operations, negative events that have occurred, and negative industry and economic trends. If the estimated fair value is less than the carrying value,amount, measurement of the impairment will be based on the difference between the carrying value and fair value of the asset group, generally determined based on the present value of expected future cash flows associated with the use of the asset.
Acquired Contract Liabilities, net
In connection with several of our acquisitions, we assumed existing long-term contracts. Based on our review of these contracts, we concluded that the terms of certain contracts to be either more or less favorable than could be realized in market transactions as of the date of the acquisition. As a result, we recognized acquired contract liabilities, net of acquired contract assets as of the acquisition date of each respective acquisition, based on the present value of the difference between the contractual cash flows of the executory contracts and the estimated cash flows had the contracts been executed at the acquisition date. The liabilities principally relate to long-term life of program contracts that were initially executed at several years prior to the respective acquisition (see Note 3 of "Notes to Consolidated Financial Statements" for further discussion).
The acquired contract liabilities, net, are being amortized as non-cash revenues over the terms of the respective contracts. The Company recognized net amortization of contract liabilities of approximately $132.4$125.1 million,, $75.7 $121.0 million and $42.6$132.4 million in the fiscal years ended March 31, 2016, 20152018, 2017 and 2014,2016, respectively, and such amounts have been included in revenues in our results of operations. The balance of the liability as of March 31, 2016,2018, is approximately $522.7$274.2 million and, based on the expected delivery schedule of the underlying contracts, the Company estimates annual amortization of the liability as follows 2017$125.2 million; 2018$117.5 million; 2019$78.0 million;68.8 million; 2020$59.7 million;63.2 million; 2021$59.1 million; $59.7 million2022;—$32.0 million; 2023—$25.1 million; Thereafter$82.6 million.26.0 million.
Postretirement Plans
The liabilities and net periodic cost of our pension and other postretirement plans are determined using methodologies that involve several actuarial assumptions, the most significant of which are the discount rate, the expected long-term rate of asset return and rate of growth for medical costs. The actuarial assumptions used to calculate these costs are reviewed annually or when a remeasurement is necessary. Assumptions are based upon management's best estimates, after consulting with outside investment advisors and actuaries, as of the measurement date.
During the fourth quarter of the fiscal year ended March 31, 2016, we changed the method we use to estimate the service and interest components of net periodic benefit cost for our pension and other postretirement benefit plans.  This new estimation approach discounts the individual expected cash flows underlying the service cost and interest cost by applying the specific spot rates derived from the yield curve used to discount the cash flows reflected in the measurement of the benefit obligation.  Historically, we estimated these service and interest cost components utilizing a single weighted-average discount rate derived from the yield curve used to measure the benefit obligation at the beginning of the period.
We made this change to provide a more precise measurement of service and interest costs by improving the correlation between projected benefit cash flows to the corresponding spot yield curve rates.  We have accounted for this change as a change in accounting estimate that is inseparable from a change in accounting principle pursuant to ASC 250, Accounting Changes and Error Corrections and accordingly have accounted for it prospectively.  While the benefit obligation measured under this approach is unchanged from that determined under the prior approach, the more granular application of the spot rates will reducereduced the service and interest cost for the pension and OPEB plans for the fiscal year ended March 31, 2017, by approximately $20.0 million. The spot rates used to determine service and interest costs for the U.S. plans ranged from 0.60% to 9.75%. Under the Company’s prior methodology, these rates would have resulted in weighted-average rates for service cost and interest cost of 3.86% for the U.S. pension plans and 3.73% for the OPEB plans. The new approach will bewas used to measure the service cost and interest cost for our pension and OPEB plans for the fiscal year ended March 31, 2017.
Effective April 1, 2015, the Company changed the period over which actuarial gains and losses are being amortized for its U.S. pension plans from the average remaining future service period of active plan participants to the average life expectancy of inactive plan participants. This change was made because the Company has determined that as of that date almost all plan participants are inactive.

The accounting corridor is a defined range within which amortization of net gains and losses is not required. The discount rates at March 31, 2016,2018, ranged from 3.252.65 - 3.93%4.01% compared to a weighted-average of 3.78%2.87 - 4.06% at March 31, 2015.2017.
The assumed expected long-term rate of return on assets is the weighted-average rate of earnings expected on the funds invested or to be invested to provide for the benefits included in the Projected Benefit Obligation ("PBO"). The expected average long-term rate of return on assets is based on several factors, including actual historical market index returns, anticipated long-term performance of individual asset classes with consideration given to the related investment strategy, plan expenses and the potential to outperform market index returns. This rate is utilized principally in calculating the expected return on plan assets component of the annual pension expense. To the extent the actual rate of return on assets realized over the course of a year differs from the assumed rate, that year's annual pension expense is not affected. The gain or loss reduces or increases future pension expense over the average remaining life expectancy of inactive plan participants. The expected long-term rate of return for fiscal 2016, 20152018, 2017 and 2014,2016, was 6.50 - 8.25%8.00%. The expected long-term rate of return for fiscal 20172019 will be 5.00 - 8.00%.
In addition to our defined benefit pension plans, we provide certain healthcarehealth care and life insurance benefits for some retired employees. Such benefits are unfunded as of March 31, 2016.2018. Employees achieve eligibility to participate in these contributory plans upon retirement from active service if they meet specified age and years of service requirements. Election to participate for eligible employees must be made at the date of retirement. Qualifying dependents at the date of retirement are also eligible for medical coverage. Current plan documents reserve our right to amend or terminate the plans at any time, subject to applicable collective bargaining requirements for represented employees. From time to time, we have made changes to the benefits provided to various groups of plan participants. Premiums charged to most retirees for medical coverage prior to age 65 are based on years of service and are adjusted annually for changes in the cost of the plans as determined by an independent actuary. In addition to this medical inflation cost-sharing feature, the plans also have provisions for deductibles, co-payments, coinsurance percentages, out-of-pocket limits, schedules of reasonable fees, preferred provider networks, coordination of benefits with other plans, and a Medicare carve-out.
In accordance with ASC 715, Compensation—Retirement Benefits, we recognized the funded status of our benefit obligation. This funded status is remeasured as of our annual remeasurement date. The funded status is measured as the difference between the fair value of the plan's assets and the PBO or accumulated postretirement benefit obligation of the plan. In order to recognize the funded status, we determined the fair value of the plan assets. The majority of our plan assets are publicly traded investments which were valued based on the market price as of the date of remeasurement. Investments that are not publicly traded were valued based on the estimated fair value of those investments as of the remeasurement date based on our evaluation of data from fund managers and comparable market data.
The Company periodically experiences events or makes changes to its benefit plans that result in curtailment or special charges. Curtailments are recognized when events occur that significantly reduce the expected years of future service of present employees or eliminates the benefits for a significant number of employees for some or all of their future service.
Curtailment losses are recognized when it is probable the curtailment will occur and the effects are reasonably estimable. Curtailment gains are recognized when the related employees are terminated or a plan amendment is adopted, whichever is applicable.
As required under ASC 715, the Company remeasures plan assets and obligations during an interim period whenever a significant event occurs that results in a material change in the net periodic pension cost. The determination of significance is based on judgment and consideration of events and circumstances impacting the pension costs.
See Note 15 of "Notes to Consolidated Financial Statements" for a summary of the key events that affected our net periodic benefit cost and obligations that occurred during the fiscal years ended March 31, 2016, 20152018, 2017 and 2014.2016.
Pension income, excluding curtailments, settlements and special termination benefits (early retirement incentives) for the fiscal year ended March 31, 2016,2018, was $57.2$61.6 million compared with pension income of $52.4$66.5 million for the fiscal year ended March 31, 2015,2017, and $35.0$57.2 million for the fiscal year ended March 31, 2014.2016. For the fiscal year ending March 31, 2017,2019, the Company expects to recognize pension income of approximately $66.5$61.5 million.
Recently Issued Accounting Pronouncements
In February 2016,May 2014, the Financial Accounting Standards Board ("FASB") issued ASU 2014-09, Revenue from Contracts with Customers ("ASU 2014-09"). Subsequently, the FASB issued several updates to ASU 2014-09, which are codified in Accounting Standards Update ("ASU"Codification (“ASC”) 2016-02,606. ASC 606 also includes new guidance on costs related to a contract, which is codified in ASC Subtopic 340-40, Leases Other Assets and Deferred Costs - Contracts with Customers.(Topic 842)

In applying ASC 606, revenue is recognized when control of promised goods or services transfers to a customer and is recognized in an amount that reflects the consideration which the entity expects to receive in exchange for those goods or services. The major provisions of the new standard include the determination of enforceable rights and obligations between parties; the identification of performance obligations, including those related to material right obligations; the allocation of consideration based upon relative standalone selling price; accounting for variable consideration; the determination of whether performance obligations are satisfied over time or at a point in time; and enhanced disclosure requirements.
ASC 606 was effective for the Company beginning April 1, 2018, and permits two methods of adoption: retrospectively to each prior reporting period presented (“full retrospective method”) or retrospectively with the cumulative effect of the initial application recognized at the date of initial application (“modified retrospective method”). ASU 2016-02 requires lesseesThe Company will adopt the standard using the modified retrospective method and will record an adjustment to retained earnings for the cumulative effect of initial application on April 1, 2018 (the “Transition Adjustment”). Contracts that are substantially completed will be excluded from the Transition Adjustment.
The Company has substantially completed its review of all contracts with customers to quantify the financial statement impact of the Transition Adjustment. Contracts with customers in the Aerospace Structures segment represent a significant portion of the Transition Adjustment.
The primary effect of the Company’s adoption of ASC 606 (outside of the Aerospace Structures segment) will be to recognize revenue over time for certain of its contracts, which is a change from recognition based on shipping terms under the pre-ASC 606 accounting policy.
The Company is in the process of completing its assessment of less prevalent contractual terms including the accounting for material rights, customer acceptance terms, and variable consideration, as well as validating certain of the inputs to the calculation of the Transition Adjustment, which are not expected to be material. The Company is also in the process of completing the calculation of the Transition Adjustment for certain subsidiaries which is not expected to have a material impact.
Based on the assessment procedures performed to date, the Company estimates the Transition Adjustment impact to decrease beginning Retained Earnings on a pre-tax basis by $550.0 million to $650.0 million which has not been tax effected as the Company is completing its evaluation. The Company does not believe the tax effect to be material since it is in a valuation allowance position. The Company will likely have an accumulated deficit after recording the Transition Adjustment, which would limit or restrict our ability to pay dividends.
The Company is in the process of implementing changes to its processes, the nature of the data it gathers and its systems to comply with the requirements of ASC 606 including implementing controls.
Upon adoption of ASC 606, the Company will no longer recognize revenue using the units-of-delivery method. ASC 606 is applied by analyzing each contract, or a combination of contracts, to determine if revenue is recognized over time or at a point in time. The Company has determined that some of its contracts will have performance obligations that are satisfied over time and some at a point in time based on when control of goods and services transfers to the customer.
For performance obligations that are satisfied over time, the Company will use an input method as the basis for recognizing revenue. Input methods recognize revenue based on an entity’s efforts or inputs toward satisfying a performance obligation (for example, resources consumed, labor hours expended, costs incurred, time lapsed, or machine hours used) relative to the total expected inputs to satisfy the performance obligation. The Company will generally use costs incurred as the measure of performance; and therefore, will generally not defer any production costs. Performance obligations that are not recognized over time will be recognized at the point in time when control transfers to the customer.
As explained above, under legacy GAAP, the Company used the units-of-delivery method and certain production costs were deferred over the life of the contract block. Under ASC 606, the Company will not use contract blocks and costs will no longer be deferred and allocated to future units as under the units-of-delivery method. Accordingly, for certain contracts related to the Aerospace Structures segment, capitalized pre-production costs of $865.8 million (pretax), net of previously recognized forward loss reserves of $344.0 million (pretax) will be eliminated and result in a decrease to retained earnings as part of the Transition Adjustment noted above.
ASC 340-40 is applied to costs to obtain or fulfill a contract if existing guidance is not applicable. The Company’s accounting for preproduction, tooling and certain other costs is expected to continue under existing guidance, since the costs generally do not fall within the scope of ASC 340-40.

The Company anticipates that in fiscal 2019, revenue for certain contracts that would have been recognized under legacy GAAP will be lower because the allocation of revenue to completed performance obligations will be accelerated into retained earnings as part of the Transition Adjustment.
The enhanced disclosure requirements of ASC 606 include discussions on the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. The Company expects the disclosures to include qualitative and quantitative information about its contracts with customers, information about contract assets and liabilities, information about the performance obligation for most leases.customer contracts and the significant judgments made in applying the guidance in ASC 606. This will result in changes to the Company's existing disclosures, as well as new disclosures, which will impact the information reported in the Company's consolidated financial statements.
In March 2017, the FASB issued ASU 2016-022017-07, Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost ("ASU 2017-07"). ASU 2017-07 requires entities to report the service cost component of net periodic pension and net periodic postretirement benefit cost in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. Further, ASU 2017-07 requires the other components of net periodic pension and net periodic postretirement benefit cost to be presented on the income statement separately from the service cost component and outside a subtotal of income from operations, if one is presented. Additionally, only the service cost component is eligible for capitalization, when applicable. The amendments as set forth in ASU 2017-07 are effective for reporting periods beginning after December 15, 2017. The Company adopted the requirements of ASU 2017-07 on April 1, 2018. The Company will apply the guidance on the presentation of the components of net periodic benefit cost in the income statement retrospectively and the guidance limiting the capitalization of net periodic benefit cost in assets to the service cost component will be applied prospectively. The Company expects the adoption of ASU 2017-07 to result in an unfavorable impact to consolidated operating profit and a corresponding favorable impact in non-operating income for each year. Further, in the first quarter fiscal 2019, the Company expects to record a charge in the range of approximately $85.0 million to $90.0 million (pre-tax) representing incremental forward losses due to the adoption. Excluding the service costs, the net periodic pension benefit for the fiscal year ended March 31, 2018, was $76.9 million.
In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging ("ASU 2017-12"), which intends to improve and simplify accounting rules around hedge accounting. ASU 2017-12 refines and expands hedge accounting for both financial (i.e., interest rate) and commodity risks. In addition, it creates more transparency around how economic results are presented, both on the face of the financial statements and in the footnotes. The new guidance is effective for annual periods beginning after December 15, 2018. Early adoption is permitted. Full retrospective application is prohibited. ASU 2016-02's transition provision are applied using a modified retrospective approach at the beginning of the earliest comparative period presented in the financial statements. The Company is currently evaluating ASU 2016-02 and has

In November 2015, the FASB issued ASU 2015-17, Income Taxes (Subtopic 740-10): Balance Sheet Classification of Deferred Taxes. ASU 2015-17 requires companies to classify all deferred tax assets and liabilities as noncurrent on the balance sheet instead of separating deferred taxes into current and noncurrent amounts.

ASU 2015-16 eliminates the requirement thatterms and conditions of share-based payment awards require an acquirer in a business combination account for measurement-period adjustments retrospectively.

Recently Adopted Accounting Pronouncements
In March 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting ("ASU 2016-09"). ASU 2016-09 identifies areas for financial statements that have not been previously issued.

The adoptionASU 2016-09 during the fiscal year ended March 31, 2018 and it did not have a material impact on the Company’sCompany's consolidated financial position, results of operations or cash flows. In accordance with ASC 2015-15, the Company has excluded debt issuance costs relating to revolving debt instrumentsstatements. The prior periods were not adjusted as a direct deduction to debt.
In May 2014, the FASB issued guidance codified in Accounting Standards Codification ("ASC") 606, Revenue Recognition - Revenue from Contracts with Customers, which amends the guidance in former ASC 605, Revenue Recognition. The objective of ASC 606 is to establish a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and will supersede mostresult of the existing revenue recognition guidance. The principle of ASC 606 is that an entity will recognize revenue at the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled. ASC 606 is effective for interim and annual reporting periods beginning after December 15, 2016, and can be adopted by the Company using either a full retrospective or modified retrospective approach, with early adoption prohibited. The Company is currently evaluating ASC 606 and has not determined the impact it may have on the Company’s consolidated results of operations, financial position or cash flows nor decided on the method of adoption.
Forward-Looking Statements
This report contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 relating to our future operations and prospects, including statements that are based on current projections and expectations about the markets in which we operate, and management's beliefs concerning future performance and capital requirements based upon current available information. Such statements are based on management's beliefs as well as assumptions made by and information currently available to management. When used in this document, words like "may," "might," "will," "expect," "anticipate," "plan," "believe," "potential," and similar expressions are intended to identify forward-looking statements. Actual results could differ materially from management's current expectations. For example, there can be no assurance that additional capital will not be required or that additional capital, if required, will be available on reasonable terms, if at all, at such times and in such amounts as may be needed by us. In addition to these factors, among other factors that could cause actual results to differ materially, are uncertainties relating to the integration of acquired businesses, general economic conditions affecting our business segments, dependence of certain of our businesses on certain key customers, the risk that we will not realize all of the anticipated benefits from acquisitions as well as competitive factors relating to the aerospace industry. For a more detailed discussion of these and other factors affecting us, see the risk factors described in "Item 1A. Risk Factors."



Item 7A.Quantitative and Qualitative Disclosures About Market Risk
Commodity Price Risk
Some contracts with our suppliers for raw materials, component parts and other goods are short-term contracts, which are subject to termination on a relatively short-term basis. The prices of our raw materials and component parts fluctuate depending on market conditions, and substantial increases in prices could increase our operating costs, which, as a result of our fixed-price contracts, we may not be able to recoup through increases in the prices of our products. We generally do not employ forward contracts or other financial instruments to hedge commodity price risk, although we continue to review a full range of business options focused on strategic risk management for all material commodities.
Any failure by our suppliers to provide acceptable raw materials, components, kits or subassemblies could adversely affect our production schedules and contract profitability. We assess qualification of suppliers and continually monitor them to control risk associated with such supply base reliance.
To a lesser extent, we also are exposed to fluctuations in the prices of certain utilities and services, such as electricity, natural gas, chemicals and freight. We utilize a range of long-term agreements to minimize procurement expense and supply risk in these areas.
Foreign Exchange Risk
In addition, even when revenues and expenses are matched, we must translate foreign denominated results of operations, assets and liabilities for our foreign subsidiaries to U.S. dollars in our consolidated financial statements. Consequently, increases and decreases in the value of the U.S. dollar as compared to the respective foreign currencies will affect our reported results of operations and the value of our assets and liabilities on our consolidated balance sheet, even if our results of operations or the value of those assets and liabilities has not changed in its original currency. These transactions could significantly affect the comparability of our results between financial periods and/or result in significant changes to the carrying value of our assets, liabilities and stockholders' equity.
We are subject to foreign currency exchange rate risk relating to receipts from customers and payments to suppliers in foreign currencies. We use foreign currency forward contracts to hedge the price risk associated with forecasted foreign denominated payments related to our ongoing business. Foreign currency forward contracts are sensitive to changes in foreign currency exchange rates. At March 31, 20162018, a 10% change in the exchange rate in our portfolio of foreign currency contracts would not have material impact on our unrealized gains. Consistent with the use of these contracts to neutralize the effect of exchange rate fluctuations, such unrealized losses or gains would be offset by corresponding gains or losses, respectively, in the remeasurement of the underlying transactions being hedged. When taken together, these forward currency contracts and the offsetting underlying commitments do not create material market risk.
Interest Rate Risk
Our primary exposure to market risk consists of changes in interest rates on borrowings. An increase in interest rates would adversely affect our operating results and the cash flow available after debt service to fund operations and expansion. In addition, an increase in interest rates would adversely affect our ability to pay dividends on our common stock, if permitted to do so under certain of our debt arrangements, including the Credit Facility. We manage exposure to interest rate fluctuations by optimizing the use of fixed and variable rate debt. As of March 31, 20162018, approximately 77%85% of our debt was fixed-rate debt. Our financing policy states that we generally maintain between 50% and 75% of our debt as fixed-rate debt however,on a portionfully leveraged basis. The ratio of our fixed-rate debt compared to our variable-rate debt was unusually high as of March 31, 2018, because we received a significant amount of customer advances in our fiscal fourth quarter, which was used to pay down our variable debt is fixed through an interest rate swap.debt. The information below summarizes our market risks associated with debt obligations and should be read in conjunction with Note 10 of "Notes to Consolidated Financial Statements."







The following table presents principal cash flows and the related interest rates. Fixed interest rates disclosed represent the weighted-average rate as of March 31, 20162018. Variable interest rates disclosed fluctuate with the LIBOR, federal funds rates and other weekly rates and represent the weighted-average rate at March 31, 2016.2018.

The Company records the allowance for doubtful accounts based on prior experience and for specific collectibility matters when they arise. The Company writes off balances against the reserve when collectibility is deemed remote. The Company's trade and other receivables are exposed to credit risk; however, the risk is limited due to the diversity of the customer base.

Inventories
The Company records inventories at the lower of cost (average-cost or specific-identification methods) or market. Costs on long-term contracts and programs in progress represent recoverable costs incurred for production or contract-specific facilities and equipment, allocable operating overhead and advances to suppliers. Pursuant to contract provisions, agencies of the U.S. Government and certain other customers have title to, or a security interest in, inventories related to such contracts as a result of advances, performance-based payments and progress payments. The Company reflects those advances and payments as an offset against the related inventory balances. The Company expenses general and administrative costs related to products and services provided essentially under commercial terms and conditions as incurred. The Company determines the costs of inventories by the first-in, first-out or average cost methods.
Work-in-process inventory includes capitalized pre-production costs. Company policy allows for the capitalization of pre-production costs after it establishes a contractual arrangement with a customer that explicitly states that the cost of recovery of pre-production costs is allowed.
Capitalized pre-production costs include nonrecurring engineering, planning and design, including applicable overhead, incurred before production is manufactured on a regular basis. Significant customer-directed work changes can also cause pre-production costs to be incurred (see Note 5 for further discussion).
Advance Payments and Progress Payments
Advance payments and progress payments received on contracts-in-process are first offset against related contract costs that are included in inventory, with any excess amount reflected in current liabilities under the Accrued expenses and Other noncurrent liabilities caption withinon the accompanying Consolidated Balance Sheets.

Property and Equipment
Property and equipment, which includesinclude equipment under capital lease and leasehold improvements, are recorded at cost and depreciated over the estimated useful lives of the related assets, or the lease term if shorter in the case of leasehold improvements, byusing the straight-line method. Buildings and improvements are depreciated over a period of 15 to 39.5 years, and machinery and equipment are depreciated over a period of 7 to 15 years (except for furniture, fixtures and computer equipment which are depreciated over a period of 3 to 10 years).
Goodwill and Intangible Assets
The Company accounts for purchased goodwill and intangible assets in accordance with Accounting Standards Codification ("ASC") 350, Intangibles—Goodwill and Other. Under ASC 350, purchased goodwill and intangible assets with indefinite lives are not amortized; rather, they are tested for impairment on at least an annual basis. Intangible assets with finite lives are amortized over their useful lives. Upon acquisition, critical estimates are made in valuing acquired intangible assets, which include, but are not limited to:to, future expected cash flows from customer contracts, customer lists, and estimating cash flows from projects when completed; tradename and market position, as well as assumptions about the period of time that customer relationships will continue; and discount rates. Management's estimates of fair value are based upon assumptions believed to be reasonable, but which are inherently uncertain and unpredictable and, as a result, actual results may differ from the assumptions used in determining the fair values.
The Company's operating segments of Aerostructures,Integrated Systems, Aerospace SystemsStructures, and Aftermarket ServicesProduct Support are also its reporting units. The Chief Executive Officer is the Company's Chief Operating Decision Maker ("CODM"). The Company's CODM evaluates performance and allocates resources based upon review of segment information. Each of the operating segments is comprisedcomposed of a number of operating units, which are considered to be components. The components, for which discrete financial information exists, are aggregated for purposes of goodwill impairment testing.testing into three reporting units. The Company's acquisition strategy is to acquire companies that complement and enhance the capabilities of the operating segments of the Company. Each acquisition is assigned to eitherone of the AerostructuresCompany's reporting unit, the Aerospace Systems reporting unit or the Aftermarket Services reporting unit.units. The goodwill that results from each acquisition is also assigned to the reporting unit to which the acquisition is allocated, because it is that reporting unit which is intended to benefit from the synergies of the acquisition.
The Company assesses whether goodwill impairment exists using both the qualitative and quantitative assessments. The qualitative assessment involves determining whether events or circumstances exist that indicate it is more likely than not that the fair value of a reporting unit is less than its carrying amount, including goodwill. If based on this qualitative assessment the Company determines it is not more likely than not that the fair value of a reporting unit is less than its carrying amount or if the Company elects not to perform a qualitative assessment, a quantitative assessment is performed using a two-step approachas required by ASC 350 to determine whether a goodwill impairment exists at the reporting unit.
The first step of the quantitative test is used to compare the carrying amount of the reporting unit's assets to the fair value of the reporting unit. If the fair value exceeds the carrying value, no further evaluation is required and no impairment loss is recognized. If the carrying amount exceeds the fair value, then an impairment loss occurs. The impairment is measured by using the second step is required to be completed,amount by which involves allocatingthe carrying value exceeds the fair value of the reporting unitnot to each asset and liability using the guidance in ASC 805, with the excess being applied to goodwill. An impairment loss occurs ifexceed the amount of the recorded goodwill exceeds the implied goodwill. The determination of the fair value of our reporting units is based, among other things, on estimates of future operating performance of the reporting unit being valued. We areThe Company is required to complete an impairment test for goodwill and record any resulting impairment losses at least annually. Changes in market conditions, among other factors, may have an impact on these estimates and require interim impairment assessments.
When performing the two-step quantitative impairment test, the Company's methodology includes the use of an income approach which discounts future net cash flows to their present value at a rate that reflects the Company's cost of capital, otherwise known as the discounted cash flow method ("DCF"). These estimated fair values are based on estimates of future cash flows of the businesses. Factors affecting these future cash flows include the continued market acceptance of the products and services offered by the businesses, the development of new products and services by the businesses and the underlying cost of development, the future cost structure of the businesses and future technological changes. The Company also incorporates market multiples for comparable companies in determining the fair value of our reporting units. Any such impairment would be recognized in full in the reporting period in which it has been identified.
DuringConsistent with the thirdCompany's policy, the Company performs an annual assessment in its fiscal fourth quarter and on an interim basis upon the occurrence of fiscal 2016, theevents or substantive changes in circumstances that indicate a reporting unit's carrying value may be less than its fair value. The Company performed an interim assessment of the fair value of ourits goodwill and indefinite-lived intangible assets due to potential indicators of impairment relatedthe Company's decision to combine the continued decline in our stock price during the third quarter. The Company's assessment focused on the AerostructuresAerospace Structures and Precision Components reporting unit since it had significantsegments into one reporting

changessegment as noted above. In accordance with ASC 350-20-35-3C, there are several potential events and circumstances that could be indicators of goodwill impairment. A change in a company's reporting unit structure is one of these events, and when this does occur, a company must perform a "before and after" test of the reporting units (see Note 1). Additionally, the Company's enhanced visibility into its economic indicators and adjusted for select changes infuture cash flows based on its annual planning process was also an indicator. Consistent with the risk adjusted discount rate to considerCompany's policy, it performed the goodwill impairment test which includes using a combination of both the current return requirements of the market and the risks inherent in the reporting unit, expected long-term growth rate and cash flow projectionsincome approaches to determine if any decline inestimate the estimated fair value of aeach reporting unit.
After performing the "before" portion of the test of the reporting units, the Company concluded that the former Precision Component's reporting unit couldhad a fair value that was lower than its carrying value by an amount of $190,227. Accordingly, the Company recorded a non-cash impairment charge during the fiscal year ended March 31, 2018, of $190,227, which is presented on the accompanying Consolidated Statements of Operations as "Impairment of intangible assets.” The decline in fair value is the result of declining revenues from production rate reductions on sun-setting programs and the slower than previously projected ramp in our development programs and the timing of associated earnings and cash flows.
The Company then performed the "after" portion of the test of the reporting units and concluded that the new reporting unit of Aerospace Structure's goodwill had a fair value that was lower than its carrying value by an amount that exceeded the remaining goodwill impairment. Wefor the reporting unit. Following the applicable accounting guidance, this impairment charge is deemed to have occurred during the Company's fiscal fourth quarter. Therefore, the Company recorded a non-cash impairment charge during the fiscal quarter ended March 31, 2018, of $345,000, which is presented on the Consolidated Statements of Operations as "Impairment of intangible assets” for the fiscal year ended March 31, 2018. The decline in fair value is the result of declining revenues from sustained production rate reductions and sun-setting programs and the slower than previously projected ramp in our development programs and the timing of associated earnings and cash flows (See Note 2 for definition of fair value levels). The assessment for the Company's Integrated Systems and Product Support reporting units indicated that their fair value exceeded their carrying amounts.
In the fourth quarter of the fiscal year ended March 31, 2017, consistent with the Company's policy, the Company performed its annual assessment of the fair value of goodwill. The Company concluded that the goodwill related to the Aerospace Structures reporting unit was not impaired as of the interimannual testing date. The Company concluded that the goodwill had a fair value that was lower than its carrying value by an amount that exceeded the remaining goodwill for the reporting unit. Accordingly, the Company recorded a non-cash impairment charge during the fourth quarter of the fiscal year ending March 31, 2017, of $266,298, which is presented on the accompanying Consolidated Statements of Operations as "Impairment of intangible assets.” The decline in fair value is the result of declining revenues from production rate reductions on sun-setting programs and the slower than previously projected ramp in our development programs and the timing of associated earnings and cash flows (See Note 2 for definition of fair value levels).
Prior to adoption of ASU 2017-04, the Company used the quantitative assessment date. However,to perform the two-step approach required by ASC 350 to determine whether a goodwill impairment exists at the reporting unit.
The first step of the quantitative test is to compare the carrying amount of the reporting unit's assets to the fair value of the reporting unit. If the fair value exceeds the carrying value, no further work is required and no impairment loss is recognized. If the carrying amount exceeds the fair value, then the second step is required to be completed, which involves allocating the fair value of the reporting unit to each asset and liability, with the excess being applied to goodwill. An impairment loss occurs if the amount of the recorded goodwill exceeds the implied goodwill. The determination of the fair value overof our reporting units is based, among other things, on estimates of future operating performance of the carrying value was within 5%reporting unit being valued. We are required to complete an impairment test for goodwill and record any resulting impairment losses at least annually.

In the fourth quarter of fiscal 2016, the Company performed the quantitative assessment for eachall three of the Company's threeformer reporting units, which indicated that the fair value of goodwill for the former Aerostructures reporting unit did not exceed its carrying amount. After evaluating whether other assets within the reporting unit were impaired in accordance with ASC 350, we concluded on the implied goodwill under Step 2amount, resulting in a $597,603 impairment of goodwill to the former Aerostructures reporting unit. The assessment for the Company's Aerospace Systems and Aftermarket Services reporting units indicated that the fair value of their respective goodwill exceeded the carrying amount. We incurred no impairment of goodwill as a result of our annual goodwill impairment tests in fiscal 2015 or 2014 (see Note 7 for further discussion).
As of March 31, 2015,2018, the Company had a $438,400 indefinite-lived$150,000 intangible asset associated with the tradenames acquired in the acquisitions of Vought Aircraft Industries, Inc. ("Vought") and Embee, Inc. ("Embee"). ThePrior to March 31, 2016, the Company assessesassessed whether indefinite-lived intangible assets impairment exists using both the qualitative and quantitative assessments. The qualitative assessment involves determining whether events or circumstances exist that indicate it is more likely than not that the fair value of an indefinite-lived intangible asset is less than its carrying amount. If based on this qualitative assessment, the Company determines it is not more likely than not that the fair value of an indefinite-lived intangible asset is less than its carrying amount or if the Company elects not to perform a qualitative assessment, a quantitative assessment is performed to determine whether an indefinite-lived intangible asset impairment exists. We test the indefinite-lived intangible assets for impairment by comparing the carrying value to the fair value based on current revenue projections of the related operations, under the relief from royalty method. Any excess of the carrying value over the amount of fair value is recognized as an impairment.
During the third quarter of the fiscal year ended March 31, 2016, the Company performed an interim assessment of fair value on our indefinite-lived intangible assets due to indicators of impairment related to the continued decline in our stock price during the fiscal third quarter. Based on the Company's evaluation,the Company concluded that the Vought tradename had a fair value of $195,800 (Level 3) compared to a carrying value of $425,000. Accordingly, the Company recorded a non-cash impairment charge during the fiscal year ended March 31, 2016, of $229,200, which is presented on the accompanying Consolidated Statements of Operations as "Impairment of intangible assets".assets." The decline in fair value compared to the carrying value of the Vought tradename is the result of declining revenues from production rate reductions and the slower than previously projected ramp in Bombardier Global 7000/8000 and the timing of associated earnings.
InDuring the fourth quarter of the fiscal year ended March 31, 2016, the Company performed its annual impairment test for each of the Company's indefinite-lived intangible assets, which indicated that the Vought and Embee tradenames had a fair value of $163,000 (Level 3) compared to a carrying value of $209,200. The decline in fair value of the tradenames is the result of the increase in discount rate during the fourth quarter of fiscal 2016, which required the Company to assess whether events and/or circumstances have changed regarding the indefinite-life conclusion. As a result the Company incurred a non-cash impairment charge of $46,200 presented on the accompanying Consolidated Statements of Operations as "Impairment of intangible assets" to the Vought and Embee tradenames. Additionally, it wastradenames and changed to a useful life of 20 years.
During the fiscal year ended March 31, 2017, as part of the Company's annual assessment, the Company determined that the tradenames will be amortized over their remaining estimated useful life for the Vought tradename should be reduced from a useful life of 20 years. The Company incurred no impairmentyears to a useful life of indefinite-lived assets10 years, as a result of our annual indefinite-lived assets impairment tests in fiscal 2015 or 2014.it better represents the financial performance relative to the expected performance.
Finite-lived intangible assets are amortized over their useful lives ranging from 3 to 3230 years. The Company continually evaluates whether events or circumstances have occurred that would indicate that the remaining estimated useful lives of long-lived assets, including intangible assets, may warrant revision or that the remaining balance may not be recoverable. Intangible assets are evaluated for indicators of impairment. When factors indicate that long-lived assets, including intangible assets, should be evaluated for possible impairment, an estimate of the related undiscounted cash flows over the remaining life of the long-lived assets, including intangible assets, is used to measure recoverability.recoverability based on the primary asset of the asset group. Some of the more important factors management considers include the Company's financial performance relative to expected and historical performance, significant changes in the way the Company manages its operations, negative events that have occurred, and negative industry and economic trends. If the estimated fair value is less than the carrying amount, measurement of the impairment will be based on the difference between the carrying value and fair value of the asset group, generally determined based on the present value of expected future cash flows associated with the use of the asset.

Deferred Financing Costs
Financing costs are deferred and amortized to Interest expense and other inon the accompanying Consolidated Statements of Operations over the related financing period using the effective interest method or the straight-line method when it does not differ materially from the effective interest method. The Company records deferred financing costs as a direct deduction from the carrying value of that debt liability; however, the policy does exclude deferred financing costs relating to revolving debt instruments. These deferred financing costs are recorded in Other, net inon the accompanying Consolidated Balance Sheets as of March 31, 20162018 and 20152017. Total deferred financing costs, net of accumulated amortization of $14,13128,445 and $17,85022,692, respectively, are recorded as of March 31, 20162018 and 20152017. Make-whole payments in connection with early debt retirements are classified as cash flows used in financing activities.

Acquired Contract Liabilities, net
In connection with several of our acquisitions, we assumed existing long-term contracts. Based on our review of these contracts, we concluded that the terms of certain contracts to be either more or less favorable than could be realized in market transactions as of the date of the acquisition. As a result, we recognized acquired contract liabilities, net of acquired contract assets as of the acquisition date of each respective acquisition, based on the present value of the difference between the contractual cash flows of the executory contracts and the estimated cash flows had the contracts been executed at the acquisition date. The liabilities principally relate to long-term life of program contracts that were initially executed at several years prior to the respective acquisition (see Note 3 for further discussion).
The Company measured these net liabilities under the measurement provisions of ASC 820, Fair Value MeasurementsMeasurement, which is based on the price to transfer the obligation to a market participant at the measurement date, assuming that the net liabilities will remain outstanding in the marketplace. Fair value estimates are based on a complex series of judgments about future events and uncertainties and rely heavily on estimates and assumptions. The judgments used to determine the estimated fair value assigned to each long-term contracts can materially impact our results of operations.
Included in the net sales of the AerostructureIntegrated Systems and Aerospace Systems groupsStructures is the non-cash amortization of acquired contract liabilities recognized as fair value adjustments through purchase accounting from various acquisitions. The Company recognized net amortization of contract liabilities of $132,363, $75,733$125,148, $121,004 and $42,629$132,363 in the fiscal years ended March 31, 2016, 20152018, 2017 and 20142016, respectively, and such amounts have been included in revenues in results of operations. The balance of the liability as of March 31, 20162018, is $522,680274,167 and, based on the expected delivery schedule of the underlying contracts, the Company estimates annual amortization of the liability as follows: 2017$125,241; 2018$117,544; 2019$77,99068,782; 2020$59,66063,241; and 2021$59,65959,098.; 2022$32,021; 2023$25,071; Thereafter $25,954.
Revenue Recognition
Revenues are generally recognized in accordance with the contract terms when products are shipped, delivery has occurred or services have been rendered, pricing is fixed or determinable and collection is reasonably assured. The Company's policy with respect to sales returns and allowances generally provides that the customer may not return products or be given allowances, except at the Company's option. Accruals for sales returns, other allowances and estimated warranty costs are provided at the time of shipment based upon past experience.
A significant portion of the Company's contracts are within the scope of ASC 605-35, Revenue Recognition —Construction-Type and Production-Type Contracts, and revenue and costs on contracts are recognized using the percentage-of-completion method of accounting. Accounting for the revenue and profit on a contract requires estimates of (1) the contract value or total contract revenue,revenue; (2) the total costs at completion, which is equal to the sum of the actual incurred costs to date on the contract and the estimated costs to complete the contract's scope of workwork; and (3) the measurement of progress towardstoward completion. Depending on the contract, the Company measures progress toward completion using either the cost-to-cost method or the units-of-delivery method, with the great majority measured under the units-of-delivery method.
Under the cost-to-cost method, progress toward completion is measured as the ratio of total costs incurred to estimated total costs at completion. Costs are recognized as incurred. Profit is determined based on estimated profit margin on the contract multiplied by progress toward completion. Revenue represents the sum of costs and profit on the contract for the period.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)
(Dollars in thousands, except per share data)

Under the units-of-delivery method, revenue on a contract is recorded as the units are delivered and accepted during the period at an amount equal to the contractual selling price of those units. The costs recorded on a contract under the units-of-delivery method are equal to the total costs at completion divided by the total units to be delivered. As contracts can span multiple years, the Company often segments the contracts into production lots for the purposes of accumulating and allocating cost. Profit is recognized as the difference between revenue for the units delivered and the estimated costs for the units delivered.
Adjustments to original estimates for a contract's revenues, estimated costs at completion and estimated total profit are often required as work progresses under a contract, as experience is gained and as more information is obtained, even though the scope of work required under the contract may not change, or if contract modifications occur. These estimates are also sensitive to the assumed rate of production. Generally, the longer it takes to complete the contract quantity, the more relative overhead that contract will absorb. The impact of revisions in cost estimates is recognized on a cumulative catch-up basis in the period in which the revisions are made. Provisions for anticipated losses on contracts are recorded in the period in which they become probable ("forward losses") and are first offset against costs that are included in inventory, with any remaining amount reflected in accrued contract liabilities in accordance with ASC 605-35. Revisions in contract estimates, if significant, can

materially affect results of operations and cash flows, as well as valuation of inventory. Furthermore, certain contracts are combined or segmented for revenue recognition in accordance with ASC 605-35.
For the fiscal year ended March 31, 20162018, cumulative catch-up adjustments resulting from changes in contract values and estimated costs that arose during the fiscal year decreased operating (loss) income,loss, net (loss) incomeloss and earnings per share by approximately $(596,213)19,677, $(539,023)13,479 and $(10.95)0.27, respectively. The cumulative catch-up adjustments to operating income for the fiscal year ended March 31, 20162018, included gross favorable adjustments of approximately $32,95485,844 and gross unfavorable adjustments of approximately $(629,167)66,167, which includes provisions for forward losses of $561,158 on the Bombardier Global 7000/8000 ("Bombardier") and 747-8 programs..
For the fiscal year ended March 31, 2015,2017, cumulative catch-up adjustments resulting from changes in estimates increased operating income, decreased net loss and increased earnings per share by approximately $57,153, $52,598 and $1.07, respectively. The cumulative catch-up adjustments to operating income for the fiscal year ended March 31, 2017, included gross favorable adjustments of approximately $163,274 and gross unfavorable adjustments of approximately $106,121 which includes a reduction to the previously recognized forward losses of $131,400 on the 747-8 program.
For the fiscal year ended March 31, 2016, cumulative catch-up adjustments resulting from changes in estimates decreased operating income, net income and earnings per share by approximately $(156,048), $(106,639)$596,213, $539,023 and $(2.09),$10.95, respectively. The cumulative catch-up adjustments to operating income for the fiscal year ended March 31, 20152016, included gross favorable adjustments of approximately $4,653$32,954 and gross unfavorable adjustments of approximately $(160,701)$629,167 which includes a provision for forward losses of $151,992$561,158 on the Bombardier Global 7000/8000 ("Bombardier") and 747-8 program.
For the fiscal year ended March 31, 2014, cumulative catch-up adjustments resulting from changes in estimates decreased operating income, net income and earnings per share by approximately $(53,166) $(35,121) and $(0.67), respectively. The cumulative catch-up adjustments to operating income for the fiscal year ended March 31, 2014 included gross favorable adjustments of approximately $14,341 and gross unfavorable adjustments of approximately $(67,507).programs.
Amounts representing contract change orders or claims are only included in revenue when such change orders or claims have been settled with the customer and to the extent that units have been delivered. Additionally, some contracts may contain provisions for revenue sharing, price re-determination, requests for equitable adjustments, change orders, or cost and/or performance incentives. Such amounts or incentives are included in contract value when the amounts can be reliably estimated and their realization is reasonably assured.
Although fixed-price contracts, which extend several years into the future, generally permit the Company to keep unexpected profits if costs are less than projected, the Company also bears the risk that increased or unexpected costs may reduce profit or cause the Company to sustain losses on the contract. In a fixed-price contract, the Company must fully absorb cost overruns, notwithstanding the difficulty of estimating all of the costs the Company will incur in performing these contracts and in projecting the ultimate level of revenue that may otherwise be achieved.
TheAs disclosed during fiscal 2016, the Company recognized a provision for forward losses associated with our long-term contractscontract on the 747-8 and Bombardier programs. ThereThere is still risk similar to what we havethe Company has experienced on the 747-8 and Bombardier programs. Particularly, ourthe Company's ability to manage risks related to supplier performance, execution of cost reduction strategies, hiring and retaining skilled production and management personnel, quality and manufacturing execution, program schedule delays, potential need to negotiate facility lease extensions or alternatively relocate work and many other risks, will determine the ultimate performance of these long-term programs.
The Aftermarket Services Group provides repair and overhaul services, certain of which services are provided under long-term power-by-the-hour contracts, comprising approximately 6% of the segment's net sales. The Company applies the proportional performance method to recognize revenue under these contracts. Revenue is recognized over the contract period as units are delivered based on the relative value in proportion to the total estimated contract consideration. In estimating the total contract consideration, management evaluates the projected utilization of its customer's fleet over the term of the contract,

in connection with the related estimated repair and overhaul servicing requirements to the fleet based on such utilization. Changes in utilization of the fleet by customers, among other factors, may have an impact on these estimates and require adjustments to estimates of revenue to be realized.
Shipping and Handling Costs
The cost of shipping and handling products is included in cost of products sold.sales.
Research and Development Expense
Research and development ("R&D") expense (which includes certain amounts subject to reimbursement from customers) was approximately $103,031, $108,062$72,763, $112,418 and $82,494$103,031 for the fiscal years ended March 31, 2016, 20152018, 2017 and 20142016, respectively.
Retirement Benefits
Defined benefit pension plans are recognized in the consolidated financial statements on an actuarial basis. A significant element in determining the Company's pension income (expense) is the expected long-term rate of return on plan assets. This expected return is an assumption as to the average rate of earnings expected on the funds invested or to be invested to provide for the benefits included in the projected pension benefit obligation. The Company applies this assumed long-term rate of return to a calculated value of plan assets, which recognizes changes in the fair value of plan assets in a systematic manner over five years. This produces the expected return on plan assets that is included in pension income (expense). The difference between this expected return and the actual return on plan assets is deferred. The net deferral of past asset gains (losses) affects the calculated value of plan assets and, ultimately, future pension income (expense).

The Company periodically experiences events or makes changes to its benefit plans that result in curtailment or special charges. Curtailments are recognized when events occur that significantly reduce the expected years of future service of present employees or eliminates the benefits for a significant number of employees for some or all of their future service.
Curtailment losses are recognized when it is probable the curtailment will occur and the effects are reasonably estimable. Curtailment gains are recognized when the related employees are terminated or a plan amendment is adopted, whichever is applicable.
As required under ASC 715, Compensation Retirement Benefits, the Company remeasures plan assets and obligations during an interim period whenever a significant event occurs that results in a material change in the net periodic pension cost. The determination of significance is based on judgment and consideration of events and circumstances impacting the pension costs.
At March 31 of each year, the Company determines the fair value of its pension plan assets as well as the discount rate to be used to calculate the present value of plan liabilities. The discount rate is an estimate of the interest rate at which the pension benefits could be effectively settled. In estimating the discount rate, the Company looks to rates of return on high-quality, fixed-income investments currently available and expected to be available during the period to maturity of the pension benefits. The Company uses a portfolio of fixed-income securities, which receive at least the second-highest rating given by a recognized ratings agency.
Fair Value Measurements
Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. When determining fair value measurements for assets and liabilities required to be recorded at fair value, the Company considers the principal or most advantageous market in which it would transact and also considers assumptions that market participants would use when pricing an asset or liability. The fair value hierarchy has three levels of inputs that may be used to measure fair value: Level 1—Unadjusted quoted prices in active markets for identical assets or liabilities; Level 2—Unadjusted quoted prices in active markets for similar assets or liabilities, or unadjusted quoted prices for identical or similar assets or liabilities in markets that are not active, or inputs other than quoted prices that are observable for the asset or liability; and Level 3—Unobservable inputs for the asset or liability. The Company has applied fair value measurements to its interest rate swapdivestitures (see Note 10)4), to its goodwill and intangible impairment tests (see Note 7) and to its pension and postretirement plan assets (see Note 15).
Foreign Currency Translation
The determination of the functional currency for the Company's foreign subsidiaries is made based on appropriate economic factors. The functional currency of the Company's subsidiaries Triumph Aviation Services—Asia and Triumph Structures—Thailand is the U.S. dollar since that is the currency in which that entity primarily generates and expends cash. The functional currency of the Company's remaining subsidiaries is the local currency, since that is the currency in which those

entities primarily generate and expend cash. Assets and liabilities of these subsidiaries are translated at the rates of exchange at the balance sheet date. Income and expense items are translated at average monthly rates of exchange. The resultant translation adjustments are included in accumulated other comprehensive income (see Note 13). Gains and losses arising from foreign currency transactions of these subsidiaries are included in net (loss) income.earnings.
Income Taxes
The Company accounts for income taxes using the asset and liability method. The asset and liability method requires recognition of deferred tax assets and liabilities for expected future tax consequences of temporary differences that currently exist between tax bases and financial reporting bases of the Company's assets and liabilities. A valuation allowance is provided on deferred taxes if it is determined that it is more likely than not that the asset will not be realized. The Company recognizes penalties and interest accrued related to income tax liabilities in the provision for income taxes in its Consolidated Statements of Operations.
Significant management judgment is required to determine the amount of benefit to be recognized in relation to an uncertain tax position. The Company uses a two-step process to evaluate tax positions. The first step requires an entity to determine whether it is more likely than not (greater than 50% chance) that the tax position will be sustained. The second step requires an entity to recognize in the financial statements the benefit of a tax position that meets the more-likely-than-not recognition criterion. The amounts ultimately paid upon resolution of issues raised by taxing authorities may differ materially from the amounts accrued and may materially impact the financial statements of the Company in future periods.
Recently Issued Accounting Pronouncements
In February 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2016-02, Leases (Topic 842). ASU 2016-02 requires lessees The Company recognizes penalties and interest accrued related to recognize assets andincome tax liabilities for most leases. ASU 2016-02 is effective for annual periods beginning after December 15, 2018. Early adoption is permitted. Full retrospective application is prohibited. ASU 2016-02's transition provision are applied using a modified retrospective approach at the beginning of the earliest comparative period presented in the financial statements. The Company is currently evaluating ASU 2016-02 and has not determined the impact it may haveprovision for income taxes on the Company’s consolidated resultsits Consolidated Statements of operations, financial position or cash flows nor decided on the method of adoption.
In November 2015, the FASB issued ASU 2015-17, Income Taxes (Subtopic 740-10): Balance Sheet Classification of Deferred Taxes. ASU 2015-17 requires companies to classify all deferred tax assets and liabilities as noncurrent on the balance sheet instead of separating deferred taxes into current and noncurrent amounts. ASU 2015-17 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. Early adoption is allowed for financial statements that have not been previously issued. Entities may elect to adopt the guidance either prospectively or retrospectively to all prior periods (i.e., the balance sheet for each period is adjusted). Effective December 1, 2015, the Company adopted this standard retrospectively to all prior periods and resulting in a reclass of $145,352 from a current deferred tax asset to a noncurrrent deferred tax liability on the Consolidated Balance Sheet. The adoption did not have a material impact on the Company’s financial position, results of operations or cash flows.
In September 2015, the FASB issued ASU 2015-16, Business Combinations(Topic 805): Simplifying the Accounting for Measurement-Period Adjustments. ASU 2015-16 eliminates the requirement that an acquirer in a business combination account for measurement-period adjustments retrospectively. Instead, an acquirer will recognize a measurement-period adjustment during the period in which it determines the amount of the adjustment. ASU 2015-16 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. Early adoption is permitted. The Company adopted this standard effective January 1, 2016. The adoption did not have a material impact on the Company's financial position, results of operations or cash flows.
In April 2015, the FASB issued ASU 2015-03, Interest—Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs. ASU 2015-03 requires companies to present debt issuance costs as a direct deduction from the carrying value of that debt liability. ASU 2015-03 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. Early adoption is allowed for financial statements that have not been previously issued. Entities would apply the new guidance retrospectively to all prior periods. Effective April 1, 2015, the Company adopted this standard. The adoption did not have a material impact on the Company’s financial position, results of operations or cash flows. In accordance with ASC 2015-15, the Company has excluded debt issuance costs relating to revolving debt instruments as a direct deduction to debt.Operations.

Recently Issued Accounting Pronouncements
In May 2014, the Financial Accounting Standards Board ("FASB") issued ASU 2014-09, Revenue from Contracts with Customers ("ASU 2014-09"). Subsequently, the FASB issued guidanceseveral updates to ASU 2014-09, which are codified in Accounting Standards Codification ("ASC"(“ASC”) 606. ASC 606 also includes new guidance on costs related to a contract, which is codified in ASC Subtopic 340-40, Revenue RecognitionOther Assets and Deferred Costs - Revenue from Contracts with Customers, which amends the guidance in former ASC 605, .Revenue Recognition. The objective of
In applying ASC 606, revenue is to establish a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and will supersede most of the existing revenue recognition guidance. The principle of ASC 606 is that an entity will recognize revenue at the transferrecognized when control of promised goods or services transfers to customersa customer and is recognized in an amount that reflects the consideration to which the entity expects to receive in exchange for those goods or services. The major provisions of the new standard include the determination of enforceable rights and obligations between parties; the identification of performance obligations, including those related to material right obligations; the allocation of consideration based upon relative standalone selling price; accounting for variable consideration; the determination of whether performance obligations are satisfied over time or at a point in time; and enhanced disclosure requirements.
ASC 606 was effective for the Company beginning April 1, 2018, and permits two methods of adoption: retrospectively to each prior reporting period presented (“full retrospective method”) or retrospectively with the cumulative effect of the initial application recognized at the date of initial application (“modified retrospective method”). The Company adopted the standard using the modified retrospective method and will record an adjustment to retained earnings for the cumulative effect of initial application on April 1, 2018 (the “Transition Adjustment”). Contracts that are substantially completed will be entitled.excluded from the Transition Adjustment.
The Company has substantially completed its review of all contracts with customers to quantify the financial statement impact of the Transition Adjustment. Contracts with customers in the Aerospace Structures segment represent a significant portion of the Transition Adjustment.
The primary effect of the Company’s adoption of ASC 606 (outside of the Aerospace Structures segment) will be to recognize revenue over time for certain of its contracts, which is a change from recognition based on shipping terms under the pre-ASC 606 accounting policy.
The Company is in the process of completing its assessment of less prevalent contractual terms including the accounting for material rights, customer acceptance terms, and variable consideration, as well as validating certain of the inputs to the calculation of the Transition Adjustment, which are not expected to be material. The Company is also in the process of completing the calculation of the Transition Adjustment for certain subsidiaries which is not expected to have a material impact.
Based on the assessment procedures performed to date, the Company estimates the Transition Adjustment impact to decrease beginning Retained Earnings on a pre-tax basis by $550,000 to $650,000 which has not been tax affected as the Company is completing its evaluation. The Company does not believe the tax effect to be material since it is in a valuation allowance position. The Company will likely have an accumulated deficit after recording the Transition Adjustment, which would limit or restrict our ability to pay dividends.
The Company is in the process of implementing changes to its processes, the nature of the data it gathers and its systems to comply with the requirements of ASC 606 including implementing controls.
Upon adoption of ASC 606, the Company will no longer recognize revenue using the units-of-delivery method. ASC 606 is applied by analyzing each contract, or a combination of contracts, to determine if revenue is recognized over time or at a point in time. The Company has determined that some of its contracts will have performance obligations that are satisfied over time and some at a point in time based on when control of goods and services transfers to the customer.
For performance obligations that are satisfied over time, the Company will use an input method as the basis for recognizing revenue. Input methods recognize revenue based on an entity’s efforts or inputs toward satisfying a performance obligation (for example, resources consumed, labor hours expended, costs incurred, time lapsed, or machine hours used) relative to the total expected inputs to satisfy the performance obligation. The Company will generally use costs incurred as the measure of performance; and therefore, will generally not defer any production costs. Performance obligations that are not recognized over time will be recognized at the point in time when control transfers to the customer.
As explained above, under legacy GAAP, the Company used the units-of-delivery method and certain production costs were deferred over the life of the contract block. Under ASC 606, the Company will not use contract blocks and costs will no longer be deferred and allocated to future units as under the units-of-delivery method. Accordingly, for certain contracts related to the Aerospace Structures segment, capitalized pre-production costs of $865,843 (pretax), net of previously recognized forward loss reserves of $343,983 (pretax) will be eliminated and result in a decrease to retained earnings as part of the Transition Adjustment noted above.

ASC 340-40 is applied to costs to obtain or fulfill a contract if existing guidance is not applicable. The Company’s accounting for preproduction, tooling and certain other costs is expected to continue under existing guidance, since the costs generally do not fall within the scope of ASC 340-40.
The Company anticipates that in fiscal 2019, revenue for certain contracts that would have been recognized under legacy GAAP will be lower because the allocation of revenue to completed performance obligations will be recognized in retained earnings as part of the Transition Adjustment.
The enhanced disclosure requirements of ASC 606 include discussions on the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. The Company expects the disclosures to include qualitative and quantitative information about its contracts with customers, information about contract assets and liabilities, information about the performance obligation for customer contracts, and the significant judgments made in applying the guidance in ASC 606. This will result in changes to the Company's existing disclosures, as well as new disclosures, which will impact the information reported in the Company's consolidated financial statements.
In March 2017, the FASB issued ASU 2017-07, Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost ("ASU 2017-07"). ASU 2017-07 requires entities to report the service cost component of net periodic pension and net periodic postretirement benefit cost in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. Further, ASU 2017-07 requires the other components of net periodic pension and net periodic postretirement benefit cost to be presented on the income statement separately from the service cost component and outside a subtotal of income from operations, if one is presented. Additionally, only the service cost component is eligible for capitalization, when applicable. The amendments as set forth in ASU 2017-07 are effective for interim and annual reporting periods beginning after December 15, 20172017. The Company adopted the requirements of ASU 2017-07 on April 1, 2018. The Company will apply the guidance on the presentation of the components of net periodic benefit cost in the income statement retrospectively and canthe guidance limiting the capitalization of net periodic benefit cost in assets to the service cost component will be adopted byapplied prospectively. The Company expects the adoption of ASU 2017-07 to result in an unfavorable impact to consolidated operating profit and a corresponding favorable impact in non-operating income for each year. Further, in the first quarter of fiscal 2019, the Company using eitherexpects to record a full retrospectivecharge in the range of approximately $85,000 to $90,000 (pre-tax) representing incremental forward losses due to the adoption. Excluding the service costs, the net periodic pension benefit for the fiscal year ended March 31, 2018 was $76,932.
In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities ("ASU 2017-12"), which intends to improve and simplify accounting rules around hedge accounting. ASU 2017-12 refines and expands hedge accounting for both financial (i.e., interest rate) and commodity risks. In addition, it creates more transparency around how economic results are presented, both on the face of the financial statements and in the footnotes. The new guidance is effective for annual periods beginning after December 15, 2018, including interim periods within those annual periods, which will be our interim period beginning April1, 2019. Early adoption is permitted, including adoption in any interim period after the issuance of ASU 2017-12. The adoption of ASU 2017-12 is not expected to have a material impact on the Company's consolidated financial statements.
In May 2017, the FASB issued ASU 2017-09, Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting ("ASU 2017-09"), which provides clarity on determining which changes to the terms and conditions of share-based payment awards require an entity to apply modification accounting under ASC 718. The new guidance is effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods, which will be our interim period beginning April 1, 2018. Early adoption is permitted, including adoption in any interim period. The amendments should be applied prospectively to an award modified on or after the adoption date. The adoption of ASU 2017-09 is not expected to have a material impact on the Company's consolidated financial statements.
In February 2016, the FASB issued ASU 2016-02, Leases (ASC 842) ("ASU 2016-02"). This update requires recognition of lease assets and lease liabilities on the balance sheet of lessees. ASC 842 is effective for fiscal years beginning after December 15, 2018 and interim reporting periods within those years, which will be our interim period beginning April 1, 2019. Early adoption is permitted. ASU 2016-02 requires a modified retrospective transition approach with early adoption prohibited.and provides certain optional transition relief. The Company is currently evaluating ASC 606 and has not determinedthe guidance to determine the impact it maywill have to the Company's consolidated financial statements.

In the fourth quarter ofDuring the fiscal year ended March 31, 2016, wethe Company recorded a $399,758 forward loss charge for the Bombardier Global 7000/8000 wing program. Under our contract for this program, we havethe Company has the right to design, develop and manufacture wing components overfor the initial 300 ship sets .Global 7000 program. The Global 7000/8000 contract provides for fixed pricing and requires usthe Company to fund certain up-front development expenses, with certain milestone payments made by Bombardier.
The Global 7000/8000 program charge resulted in the impairment of previously capitalized pre-production costs due to the combination of cost recovery uncertainty, higher than anticipated non-recurringnonrecurring costs and increased forecasted costs on recurring production. The increases in costs were driven by several factors, including:including changing technical requirements, increased spending on the design and engineering phase of the program and uncertainty regarding cost reduction and cost recovery initiatives with our customer and suppliers.
The Global 7000/8000 program has continued to incur costs since March 2016 in support of the development and transition to production.

In May 2017, Triumph Aerostructures and Bombardier entered into a comprehensive settlement agreement that resolved all outstanding commercial disputes between them, including all pending litigation, related to the design, manufacture and supply of wing components for Bombardier’s Global 7000 business aircraft. The settlement reset the commercial relationship between the companies and allows each company to better achieve its business objectives going forward.
Further cost increases or an inability to meet revised recurring cost forecasts on the Global 7000/8000 program may result in additional forward loss reserves in future periods, while improvements in future costs compared to current estimates may result in favorable adjustments if forward loss reserves are no longer required.
The Company is still in the pre-productionearly production stages for the Bombardier and Embraer programs, as these aircrafts are not scheduled to enter service untilin calendar 2018, or later. Transition of these programs from development to recurring production levels is

Consistent with the Company's policy described here within, the Company performs Step 1 of the goodwill impairment test on an interim basis upon the occurrence of events or substantive changes in circumstances that indicate a reporting unit's carrying value may be less than its fair value. During the third quarter of the fiscal year ended March 31, 2016, the Company performed an interim assessment of the fair value of its goodwill and indefinite-lived intangible assets due to indicators of impairment related to the continued decline in the Company's stock price during the third quarter. The Company performed Step 1 of the goodwill impairment test which included using a combination of both the market and income approaches to estimate the fair value of each reporting unit.

As of the market and the risks inherent in the reporting unit, expected long-term growth rate and cash flow projections to determine if any decline in the estimated fair value of a reporting unit could result in a goodwill impairment. The decline in fair value compared to carrying value of the goodwill is the result of declining revenues from production rate reductions and the slower than previously projected ramp in Bombardier Global 7000/8000 and the timing of associated earnings. The Company concluded that the goodwill was not impaired as of the interim impairment assessment date. However, the excess of the fair value over the carrying value was within 5% for the Aerostructures reporting unit. The amount of goodwill for the Aerostructures reporting unit amounted to $1,420,195 at December 31, 2015.
During the fourth quarter of the fiscal year ended March 31, 2016, consistent with the Company's policy described here within, the Company performed its annual assessment2018, Aerospace Structures had goodwill of the fair value of goodwill. The Company concluded that the goodwill related to the Aerostructures reporting unit$1,399,128, which was impaired as of the annual testing date. The Company concluded that the goodwill had an implied fair value of $822,801 (Level 3) compared to a carrying value of $1,420,195. Accordingly, the Company recorded a non-cash impairment charge during the fourth quarter of the fiscal year ending March 31, 2016, of $597,603, which is presented on the accompanying Consolidated Statements of Operations as "Impairment of intangible assets". The decline in fair value is the result of continued declines in stock price and related market multiples for stock price to EBITDA of both the Company and our peer group. Going forward, the Company will continue to monitor the performance of this reporting unit in relation to the key assumptions in our analysis.fully impaired.
In the event that market multiples for stock price to EBITDA in the aerospace and defense markets decrease, or the expected EBITDA and cash flows for the Company's reporting units decreases, an additional goodwill impairment charge may be required, which would adversely affect the Company's operating results and financial condition. If management determines that impairment exists, the impairment will be recognized in the period in which it is identified.

During the third quarter of the fiscal year ended March 31, 2016, the Company performed an interim assessment of fair value on our indefinite-lived intangible assets due to indicators of impairment related to the continued decline in our stock price during the fiscal third quarter. The Company estimated the fair value of the tradenames using the relief-from-royalty method, which uses several significant assumptions, including revenue projections that consider historical and estimated future results, general economic and market conditions, as well as the impact of planned business and operational strategies. The following estimates and assumptions were also used in the relief-from-royalty method:

The Company follows the Income Taxes topic of ASC 740, which prescribes a recognition threshold and measurement attribute criteria for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return, as well as guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition.
On December 22, 2017, the U.S. government enacted comprehensive tax legislation referred to as the Tax Cuts and Jobs Act (the “Act”). Some of the more significant changes that impact the Company included in the Act are reductions in the corporate federal income tax rate from 35% to 21%, the elimination of the domestic manufacturing deduction, the ability to immediately expense certain property for specific tax years, the requirement for companies to pay a one-time transition tax on earnings of certain foreign subsidiaries that were previously tax deferred, and new taxes on certain foreign sourced earnings as the U.S. transitions to a territorial tax system.
The staff of the SEC has recognized the complexity of reflecting the impacts of the Act, and, on December 22, 2017, issued guidance in Staff Accounting Bulletin 118 (“SAB 118”). SAB 118 clarifies accounting for income taxes under ASC Topic 740, Income Taxes, if information is not yet available or complete and provides for up to a one-year period in which to complete the required analyses and accounting ("the measurement period"). SAB 118 describes three scenarios (or “buckets”) associated with a company’s status of accounting for income tax reform: (1) a company is complete with its accounting for certain effects of tax reform, (2) a company is able to determine a reasonable estimate for certain effects of tax reform and records that estimate as a provisional amount, or (3) a company is not able to determine a reasonable estimate and therefore continues to apply ASC 740, based on the provisions of the tax laws that were in effect immediately prior to the Act being enacted.
At March 31, 2018, the Company has not completed its accounting for the tax effects of enactment of the Act; however, the Company has made a reasonable estimate of the effects on our existing deferred tax balances and the one-time transition tax. For the items for which the Company was able to determine a reasonable estimate, the Company recognized a provisional tax benefit of $23,398, which is included as a component of income tax expense from continuing operations.
The Company has recorded a provisional tax benefit of $24,573 related to the impact of the Act’s reduction in the statutory tax rate on its net deferred tax liability, as well as a provisional tax liability of $2,175 imposed on unremitted foreign earnings under the Act’s mandatory repatriation provisions. While the Company believes these are reasonable estimates of the impact of the Act, additional time is needed to finalize these estimates. While the Company has computed and recorded these provisional amounts, these will be finalized within the established measurement period (not to exceed one year) as additional data and

(Dollars in thousands, except per share data)

information is gathered. The Company determined that the amounts recorded are provisional as adjustments may occur due to additional guidance from the IRS and as certain tax positions are finalized when the Company files its 2018 tax returns.
Due to the legislative changes aforementioned, companies need to continually reevaluate their indefinite assertion. Additional withholding taxes and/or deferred tax liability associated with basis differences may be required, but due to the legislative uncertainty around the withholding taxes on distributions under the Act, no estimate has been recorded as of March 31, 2018. This will be analyzed within the proscribed measurement period. The Company continues to review the anticipated impacts around the base erosion anti-abuse tax (“BEAT”) and the global intangible low taxed income (“GILTI”) which are effective April 1, 2018. The Company has not recorded any impact of these provisions as of March 31, 2018 but plans to perform a full analysis within the proscribed measurement period.
A valuation allowance, if needed, reduces deferred tax assets to the amount expected to be realized. When determining the amount of net deferred tax assets that are more likely than not to be realized, the Company assesses all available positive and negative evidence. This evidence includes, but is not limited to, prior earnings history, expected future earnings, carry-back and carry-forward periods and the feasibility of ongoing tax strategies that could potentially enhance the likelihood of the realization of a deferred tax asset. The weight given to the positive and negative evidence is commensurate with the extent the evidence may be objectively verified. As such, it is generally difficult for positive evidence regarding projected future taxable income exclusive of reversing taxable temporary differences to outweigh objective negative evidence of recent financial reporting losses.
Based on these criteria and the relative weighting of both the positive and negative evidence available, and in particular the activity surrounding the Company's prior earnings history, including the forward losses and intangible impairments previously recognized, management determined that it was necessary to establish a valuation allowance against principally all of its net deferred tax assets at March 31, 2016. Given the objectivity verifiable negative evidence of a three-year cumulative loss and the weighting of all available positive evidence, the Company excluded projected taxable income (aside from reversing taxable

temporary differences) from the assessment of income that could be used as a source of taxable income to realize the deferred tax assets. Valuation allowances recorded
During the fiscal year ended March 31, 2018, the Company increased the valuation allowance against the consolidated net deferred tax asset by $5,556. The impact of the Act resulted in fiscal 2016 were $155,774.a decrease of $9,312 to the valuation allowance with the remaining change attributable to increased valuation allowance on foreign deferred tax assets and other changes in net domestic deferred tax assets. As of March 31, 2018, management determined that it was necessary to maintain a valuation allowance against principally all of its net deferred tax assets.
As of March 31, 20162018, the Company has federal and state net operating loss carryforwards of $589,548131,352, $889,234 and $157,894 expiring in various years through 2035. The Company also has afor U.S. federal, state and foreign net operating loss carryforward of $109,532.jurisdictions, respectively.
The effective income tax rate for the fiscal year ended March 31, 2016,2018, was 9.6%7.9% as compared to 31.7%(81.9)% for the fiscal year ended March 31, 2015.2017. The effective income tax rate for the fiscal year ended March 31, 2016,2018, included the benefit of $5,592 from a decrease to the state deferred tax rate, the benefit from the retroactive reinstatement of the R&D tax credit of $8,443$14,878, the benefit of the foreign tax credit of $5,385, the benefit from the Act of $23,398 and the change in the valuation allowance of $155,774.$15,575 (exclusive of the reduction in the valuation allowance attributable to the Act). The effective tax rate was also impacted by the non-deductible portion of the goodwill impairment of $183,067.$136,532. Due to the current year pre-tax loss, the effective tax rate drivers on a percentage basis are amplified. Accordingly, a year-over-year comparison of the effective tax rate may not be indicative of changes in the Company's tax position.
The Company has been granted income tax holiday as an incentive to attract foreign investment by the Government of Thailand. The tax holidays expire in various years through 2026. We do not have any other tax holidays in the jurisdictions in which we operate. The income tax benefit attributable to the tax status of our subsidiaries in Thailand was approximately $1,530 or $0.03 per diluted share in fiscal 2018, $928 or $0.02 per diluted share in fiscal 2017 and $(439) or $(0.01)$(0.01) per diluted share in fiscal 2016, $1,930 or $0.04 per diluted share in fiscal 2015 and $347 or $0.01 per diluted share in fiscal 2014.
At March 31, 2016,2018, cumulative undistributed earnings of foreign subsidiaries, for which no U.S. income or foreign withholding taxes have been recorded is $74,363107,321. As the Company currently intends to indefinitely reinvest all such earnings, no provision has been made for income taxes that may become payable upon distribution of such earnings, and it is not practicable to determine the amount of the related unrecognized deferred income tax liability.
The Company has classified uncertain tax positions as noncurrent income tax liabilities unless expected to be paid in one year. Penalties and tax-related interest expense are reported as a component of income tax expense. As of March 31, 20162018 and 20152017, the total amount of accrued income tax-related interest and penalties was $239327 and $207282, respectively.

During the fiscal years ended March 31, 2016, 20152018, 2017 and 20142016, the Company added $32, $4$45, $43 and $32 of interest and penalties related to activity for identified uncertain tax positions, respectively.
As of March 31, 20162018 and 20152017, the total amount of unrecognized tax benefits was $9,21211,532 and $8,34810,266, respectively, all of which would impact the effective rate, if recognized. The Company anticipates that total unrecognized tax benefits may be reduced by $0zero in the next 12 months.
With a few exceptions, the Company is no longer subject to U.S. federal income tax examinations for fiscal years ended before March 31, 2011, U.S. federal income tax examinations for fiscal years ended March 31, 2012 and 2013, state or local examinations for fiscal years ended before March 31, 2012,2013, or foreign income tax examinations by tax authorities for fiscal years ended before March 31, 2010.2011.
As of March 31, 2016,2018, the Company is subject to examination in 1one state and no foreign jurisdictions. The Company has filed appeals in a prior state examination related to fiscal years ended March 31, 1999 through March 31, 2005. Because of net operating losses acquired as part of the acquisition of Vought, the Company is subject to U.S. federal income tax examinations and various state jurisdiction examinations for the years ended December 31, 2001,2002, and after related to previously filed Vought tax returns. The Company believes appropriate provisions for all outstanding issues have been made for all jurisdictions and all open years.

15.EMPLOYEE BENEFIT PLANS
Defined Contribution Pension Plan
The Company sponsors a defined contribution 401(k) plan, under which salaried and certain hourly employees may defer a portion of their compensation. Eligible participants may contribute to the plan up to the allowable amount as determined by the plan of their regular compensation before taxes. The Company generally matches contributions up to 50% of the first 6% of compensation contributed by the participant. All contributions and Company matches are invested at the direction of the employee in one or more investment options offered under the plan. Company matching contributions vest immediately and aggregated $17,46213,616, $20,02014,163 and $21,20817,462 for the fiscal years ended March 31, 2016, 20152018, 2017 and 20142016, respectively.
Defined Benefit Pension and Other Postretirement Benefit Plans
The Company sponsors several defined benefit pension plans covering some of its employees. Most employees are ineligible to participate in the plans or have ceased to accrue additional benefits under the plans. Benefits under the defined benefit plans are based on years of service and, for most non-represented employees, on average compensation for certain years. It is the Company's policy to fund at least the minimum amount required for all qualified plans, using actuarial cost methods and assumptions acceptable under applicable government regulations, by making payments into a trust separate from us.
In addition to the defined benefit pension plans, the Company provides certain health care and life insurance benefits for eligible retired employees. Such benefits are unfunded as of March 31, 20162018. Employees achieve eligibility to participate in these contributory plans upon retirement from active service if they meet specified age and years of service requirements. Election to participate for some employees must be made at the date of retirement. Qualifying dependents of eligible retirees at the date of retirement are also eligible for medical coverage. Current plan documents reserve the right to amend or terminate the plans at any time, subject to applicable collective bargaining requirements for represented employees. From time to time, changes have been made to the benefits provided to various groups of plan participants. Premiums paid by the Company for most retirees for medical coverage prior to age 65 are capped and are based on years of service. Overall premiums are adjusted annually for changes in the cost of the plans as determined by an independent actuary. In addition to this medical inflation cost-sharing feature, the plans also have provisions for deductibles, co-payments, coinsurance percentages, out-of-pocket limits, schedules of reasonable fees, preferred provider networks, coordination of benefits with other plans and a Medicare carve-out.
The Company also sponsors an unfunded supplemental executive retirement plan ("SERP") that provides retirement benefits to certain key employees.
In accordance with ASC 715, the Company has recognized the funded status of the benefit obligation as of March 31, 20162018 and 2015, in2017, on the accompanying Consolidated Balance Sheets. The funded status is measured as the difference between the fair value of the plans' assets and the PBO or accumulated postretirement benefit obligation of the plan. The majority of the plan assets are publicly traded investments which were valued based on the market price as of the measurement date. Investments that are not publicly traded were valued based on the estimated fair value of those investments based on our evaluation of data from fund managers and comparable market data.
The following table sets forth the Company's consolidated defined benefit pension plans for its union and non-union employees and its SERP as of March 31, 20162018 and 20152017, and the amounts recorded inon the Consolidated Balance Sheets at March 31, 20162018 and 20152017. Company contributions include amounts contributed directly to plan assets and indirectly as benefits are paid from the Company's assets. Benefit payments reflect the total benefits paid from the plans and the Company's assets. Information on the plans includes both the domestic qualified and nonqualified plans and the foreign qualified plans.

The discount rate is determined annually as of each measurement date, based on a review of yield rates associated with long-term, high-quality corporate bonds. At the end of each year, the discount rate is primarily determined using the results of bond yield curve models based on a portfolio of high-quality bonds matching notional cash inflows with the expected benefit payments for each significant benefit plan.
The expected return on plan assets is determined based on a market-related value of plan assets, which is a smoothed asset value.  The market-related value of assets is calculated by recognizing investment performance that is different from that expected on a straight-line basis over five years.  Actuarial gains and losses are amortized over the average remaining life expectancy of inactive participants for plans that are predominantly inactive and over the expected future service for active participants for other plans, but only to the extent unrecognized gains or losses exceed a corridor equal to 10% of the greater of the projected benefit obligation or market-related value of assets.
During the fourth quarter of the fiscal year ended March 31, 2016, the Company changed the method it uses to estimate the service and interest components of net periodic benefit cost for the Company’s pension and other postretirement benefit plans.  This new estimation approach discounts the individual expected cash flows underlying the service cost and interest cost by applying the specific spot rates derived from the yield curve used to discount the cash flows reflected in the measurement of the benefit obligation.  Historically, the Company estimated these service and interest cost components utilizing a single weighted-average discount rate derived from the yield curve used to measure the benefit obligation at the beginning of the period.
The Company made this change to provide a more precise measurement of service and interest costs by improving the correlation between projected benefit cash flows to the corresponding spot yield curve rates. The Company has accounted for this change as a change in accounting estimate that is inseparable from a change in accounting principle pursuance to ASC 250, Accounting Changes and Error Corrections, and accordingly have accounted for it prospectively.  While the benefit obligation measured under this approach is unchanged from that determined under the prior approach, the more granular application of the spot rates will reducereduced the service and interest cost for the pension and OPEB plans for the fiscal year ending March 31, 2017, by approximately $20,000. The spot rates used to determine service and interest costs the U.S. plans ranged from 0.60%to 9.75%. Under the Company’s prior methodology, these rates would have resulted in weighted-average rates for service cost and interest

cost of 3.86% for the U.S. Pension plans and 3.73% for the OPEB plans. The new approach will bewas used to measure the service cost and interest cost for our pension and OPEB plans forbeginning with the fiscal year ending March 31, 2017.
Effective April 1, 2015, the Company changed the period over which actuarial gains and losses are being amortized for its U.S. pension plans from the average remaining future service period of active plan participants to the average life expectancy of inactive plan participants. This change was made because the Company has determined that as of that date almost all plan participants are inactive.
During the fiscal year ended March 31, 2015,2018, the Society of Actuaries released a new mortality tablesprojection scale that reflect increased life expectancyreduced expected future mortality improvements for participants of U.S. pension plans. The Company has reflected these new tables, along with an updatedthis projection scale of mortality improvements, in the measurement of our U.S. pension and other postretirement benefit plans as of March 31, 2015.201. This change resulted in an increasea decrease in the benefit obligation.
The Company periodically experiences events or makes changes to its benefit plans that result in curtailment or special charges. Curtailments are recognized when events occur that significantly reduce the expected years of future service of present employees or eliminates the benefits for a significant number of employees for some or all of their future service.
Curtailment losses are recognized when it is probable the curtailment will occur and the effects are reasonably estimable. Curtailment gains are recognized when the related employees are terminated or a plan amendment is adopted, whichever is applicable.
As required under ASC 715, the Company remeasures plan assets and obligations during an interim period whenever a significant event occurs that results in a material change in the net periodic pension cost. The determination of significance is based on judgment and consideration of events and circumstances impacting the pension costs.
The following summarizes the key events whose effects on net periodic benefit cost and obligations are included in the tables above:
In March 2018, the Company ratified a new collective bargaining agreement with a group of union-represented employees, who were working without an agreement. The agreement resulted in plan amendments for one of our pension plans and our postretirement welfare benefit plan. These amendments eliminated future service under the plans and generated curtailments, which accelerated $11,146 of prior service credits for the postretirement welfare benefits plan and accelerates $29 of prior service costs for the pension plan. These amounts were included in "Curtailment and settlement gain, net" on the Consolidated Statement of Operations.
In November 2017, the Company announced an amendment to the postretirement welfare benefits plan for its non-represented employee participants. Effective January 1, 2018, the Company eliminated and reduced certain welfare benefits for non-represented retirees and active participants. Those changes resulted in a decrease in the OPEB obligation of $17,652 and a curtailment gain of $15,099 included in "Curtailment and settlement gain, net" on the Consolidated Statement of Operations.
In March 2016, one of the Company's union-represented groups of employees ratified a new collective bargaining agreement. The agreement includes an amendment to the other postretirement benefitswelfare plan, for which participants will no longer receive a benefit after the fiscal year ended March 31, 2016. This change resulted in the termination of the plan and as a result, the plan's liability was eliminated as of March 31, 2016, and the Company recognized a credit of approximately $2,297. Additionally, the agreement includes an amendment to the pension plan, under which participants will no longer continue to accrue a benefit after the fiscal year ending March 31, 2021. This change resulted in a curtailment gain of approximately $1,516 and is presented on the accompanying Consolidated Statements of Operations within "Curtailments, settlements and early retirement incentives."
In February 2016, one of the Company's union-represented groups of employees ratified a new collective bargaining agreement. The agreement includes an amendment to the pension plan, under which effective January 1, 2017, actively accruing participants will no longer accrue benefits once they reach 30 years of service under the plan. This change resulted in a curtailment gain of approximately $3,314 and is presented on the accompanying Consolidated Statements of Operations within "Curtailments, settlements and early retirement incentives."
In May 2015 and February 2016 the Company offered enhanced retirement benefits to employees of one of its union-represented groups. In order to receive these enhanced benefits, eligible employees had to agree to retire within a special window period. This change resulted in a special termination charge of approximately $724 and is presented

on the accompanying Consolidated Statements of Operations within "Curtailments, settlements and early retirement incentives."
In April 2015, the Company's largest union-represented group of employees ratified a new collective bargaining agreement. The agreement includes an amendment to the pension plan, under which participants will no longer accrue benefits after 30 years of service under the plan. This change resulted in a curtailment gaincharge of approximately $2,863 and is presented on the accompanying Consolidated Statements of Operations within "Curtailments, settlements and early retirement incentives."
In March 2014, the Company announced an amendment to the retirement plan of its non-represented employee participants. Effective March 1, 2015, actively accruing participants with 30 years of service will no longer continue to accrue a benefit. Those changes resulted in a decrease in the projected pension obligation of $14,355 and a related

curtailment gain of $8,427 and is presented on the accompanying Consolidated Statements of Operations as "Curtailments, settlements and early retirement incentives".
In March 2014, in connection with the Company's relocation plan, the Company has restructured the remaining workforce resulting in the termination of a number of defined benefit plan participants. The Company concluded that these terminations will result in a significant reduction in the remaining service period and recorded a curtailment loss of $8,031 and is presented on the accompanying Consolidated Statements of Operations as "Curtailment, settlements and early retirement incentives". This curtailment loss included an increase in the projected pension obligation of $6,503. Additionally, as part of the layoffs, the Company recorded an early retirement incentive severance charge of $916 and is presented on the accompanying Consolidated Statements of Operations in "Curtailments, settlements and early retirement incentives."
In December 2013, the Company completed an incentive offer in the form of lump-sum payments to non-represented deferred vested employees who were not of retirement age in lieu of any future benefits. In addition, cumulative lump-sum payments to union-represented plan participants for previously offered early retirement incentives exceeded the service and interest costs of the respective plan. The aforementioned changes led to a remeasurement of the affected plan's assets and obligations as of December 2013, which resulted in a $118,391 decrease in projected benefit obligation. Additionally, these distributions resulted in settlement charges of $1,561 and are presented on the accompanying Consolidated Statements of Operations within "Curtailments, settlements and early retirement incentives."

Asset/liability studies are conducted on a regular basis to provide guidance in setting investment goals for the pension portfolio and its asset allocation. The asset allocation aims to prudently achieve a strong, risk-adjusted return while seeking to minimize funding level volatility and improve the funded status of the plans. The pension plans currently employ a liability-driven investment ("LDI") approach, where assets and liabilities move in the same direction. The goal is to limit the volatility of the funding status and cover part, but not all, of the changes in liabilities. Most of the liabilities' changes are due to interest rate movements.
To balance expected risk and return, allocation targets are established and monitored against acceptable ranges. All investment policies and procedures are designed to ensure that the plans' investments are in compliance with the Employee Retirement Income Security Act of 1974 ("ERISA"). Guidelines are established defining permitted investments within each asset class. Each investment manager has contractual guidelines to ensure that investments are made within the parameters of their asset class or in the case of multi-asset class managers, the parameters of their multi-asset class strategy. Certain investments are not permitted at any time, including investment directly in employer securities and uncovered short sales.
The tables below provide the fair values of the Company's plan assets at March 31, 20162018 and 20152017, by asset category. The table also identifies the level of inputs used to determine the fair value of assets in each category (see Note 2 for definition of levels).

All other
Investments in commingled investment funds for which the Company usesand private equity and infrastructure funds are carried at NAV as a practical expedient to estimate fair value per unit are categorized as Level 2 as long as they do not have redemption restrictions as of the measurement date. All commingled investment funds with redemption restrictions as of the measurement date are categorized as Level 3, if any.value. The NAV is the total value of the fund divided by the number of shares outstanding. Adjustments to NAV, if any, are determined based on evaluation of data provided by fund managers, including valuation of the underlying investments derived using inputs such as cost, operating results, discounted future cash flows and market-based comparable data. In accordance with Subtopic 820-10, investments that are measured at NAV practical expedient are not classified in the fair value hierarchy; however, their fair value amounts are presented in these tables to permit reconciliation of the fair value hierarchy to the total plan assets disclosed in this footnote.

Assumptions and Sensitivities
The discount rate is determined as of each measurement date, based on a review of yield rates associated with long-term, high-quality corporate bonds. The calculation separately discounts benefit payments using the spot rates from a long-term, high-quality corporate bond yield curve.
The effect of a 25 basis-point change in discount rates as of March 31, 2016,2018, is shown below:

The long-term rate of return assumption represents the expected average rate of earnings on the funds invested to provide for the benefits included in the benefit obligations. The long-term rate of return assumption is determined based on a number of factors, including historical market index returns, the anticipated long-term asset allocation of the plans, historical plan return data, plan expenses and the potential to outperform market index returns. For fiscal 20116,2018, the expected long-term rate of return on assets was 6.50 - 8.25%8.00%. For fiscal 2017,2019, the expected long-term rate of return is 6.505.00 - 8.00%.
A significant factor used in estimating future per capita cost of covered health care benefits for our retirees and us is the health care cost trend rate assumption. The rate used at March 31, 2016,2018, was 6.60%6.40% and is assumed to decrease gradually to 4.50% by fiscal 2027 and remain at that level thereafter.

The Company has stock incentive plans under which employees and non-employee directors may be granted optionsequity awards to purchaseacquire shares of the Company's common stock at the fair value at the time of the grant. EmployeeThe stock incentive and compensation plans under which outstanding equity awards have been granted to employees, officers and non-employee directors are the Triumph Group 2013 Equity and Cash Incentive Plan (the “2013 Plan”), the 2016 Directors’ Equity Compensation Plan, as amended (the “Directors’ Plan”), the Triumph Group 2004 Stock Incentive Plan (the “2004 Plan”), and the Amended and Restated Directors’ Stock Incentive Plan (the “Prior Directors’ Plan”). No new awards have been made under the 2004 Plan after the 2013 Plan was approved by the Board and the stockholders. The Prior Directors’ Plan expired by its terms during fiscal 2017. The current stock incentive and compensation plans used for future awards are the 2013 Plan for employees, officers and consultants, and the Directors’ Plan, provided, that the Directors’ Plan remains subject to stockholder approval at the 2017 annual meeting. In addition, in April 2016, the Board approved a separate employment inducement plan under which stock options and non-employee director optionsrestricted stock awards were granted to Daniel J. Crowley as new hire and retention awards (the “Crowley Plan”). The 2013 Plan, the Directors’ Plan, the 2004 Plan and the Prior Directors’ Plan are fully vestedcollectively referred to in this note as of March 31, 2016.

The restricted shares are subject to forfeiture should the grantee's employment be terminated prior to the third or fourth anniversary of the date of grant, and are included in capital in excess of par value. Restricted shares generally vest in full after three or four years. The fair value of restricted shares under the Company's restricted stock plans is determined by the product of the number of shares granted and the grant date market price of the Company's common stock. CertainMost of these awards contain performance conditions, in addition to service conditions. The fair value of restricted shares is expensed on a straight-line basis over the requisite service period of three or four years.
The Company recognized $2,6577,949, $1,2727,922 and $4,6532,657 of share-based compensation expense during the fiscal years ended March 31, 2016, 20152018, 2017 and 20142016, respectively.

Other
Certain of the Company's business operations and facilities are subject to a number of federal, state, local and foreign environmental laws and regulations. Former owners generally indemnify the Company for environmental liabilities related to the assets and businesses acquired which existed prior to the acquisition dates. In the opinion of management, there are no significant environmental contingent liabilities which would have a material effect on the financial condition or operating results of the Company which are not covered by such indemnification.
The Company's risk related to pension projected obligations as of March 31, 2016,2018, is significant. This amount is currently in excess of the related plan assets. Benefit plan assets are invested in a diversified portfolio of investments in both the equity and debt categories, as well as limited investments in real estate and other alternative investments. The market value of all of these investment categories may be adversely affected by external events and the movements and volatility in the financial markets, including such events as the current credit and real estate market conditions. Declines in the market values of our plan assets could expose the total asset balance to significant risk which may cause an increase to future funding requirements. The Company's potential risk related to OPEB projected obligations as of March 31, 2016,2018, is also significant.
Some raw materials and operating supplies are subject to price and supply fluctuations caused by market dynamics. The Company's strategic sourcing initiatives seek to find ways of mitigating the inflationary pressures of the marketplace. In recent years, these inflationary pressures have affected the market for raw materials. However, the Company believes that raw material prices will remain stable through the remainder of fiscal 20172019 and after that, experience increases that are in line with inflation. Additionally, the Company generally does not employ forward contracts or other financial instruments to hedge commodity price risk.
The Company's suppliers' failure to provide acceptable raw materials, components, kits and subassemblies would adversely affect production schedules and contract profitability. The Company maintains an extensive qualification and performance surveillance system to control risk associated with such supply base reliance. The Company is dependent on third parties for certain information technology services. To a lesser extent, the Company is also exposed to fluctuations in the prices of certain utilities and services, such as electricity, natural gas, chemical processing and freight. The Company utilizes a range of long-term agreements and strategic aggregated sourcing to optimize procurement expense and supply risk in these categories.
In the ordinary course of business, the Company is also involved in disputes, claims and lawsuits with employees, suppliers and customers, as well as governmental and regulatory inquiries, that it deems to be immaterial. Some may involve claims or potential claims of substantial damages, fines or penalties. While the Company cannot predict the outcome of any pending or future litigation or proceeding and no

potential claims of substantial damages, fines, penalties or injunctive relief. While the Company cannot predict the outcome of any pending or future litigation or proceeding and no assurances can be given, the Company does not believe that any pending matter will have a material effect, individually or in the aggregate, on its financial position or results of operations.

Evaluation of Disclosure Controls and Procedures
We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our Exchange Act reports is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms, and that such information is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, 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 evaluating the cost-benefit relationship of possible controls and procedures.
As of March 31, 20162018, we completed an evaluation, under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, of the effectiveness of the design and operation of our disclosure controls and procedures. Based on the foregoing, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures were effective at the reasonable assurance level as of March 31, 20162018.

MANAGEMENT'S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING
The management of Triumph Group, Inc. ("Triumph") is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934. Triumph's internal control system over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with U.S. generally accepted accounting principles. The Company's internal control over financial reporting includes those policies and procedures that:
(i)pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company;
(ii)provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with U.S. 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
(iii)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 inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation. Also, projections of any evaluation of effectiveness to future periods are subject to risk that controls may become inadequate because of changes in condition, or that the degree of compliance with the policies or procedures may deteriorate.
Triumph's management assessed the effectiveness of Triumph's internal control over financial reporting as of March 31, 20162018. In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) ("COSO") in Internal Control—Integrated Framework. Based on management's assessment and those criteria, management believes that Triumph maintained effective internal control over financial reporting as of March 31, 20162018.
Management's assessment of and conclusion on the effectiveness of Triumph's internal control over financial reporting did not include the internal controls of Triumph Thermal Systems - Maryland, which was acquired in the fiscal year ended March 31, 2016. The acquisition, which is more fully discussed in Note 3 to the consolidated financial statements for fiscal 2016, is included in the fiscal 2016 consolidated financial statements of Triumph Group, Inc. and represented total assets of approximately $61 million or 1% at March 31, 2016, and revenues of approximately $18 million or 0.5% for the year ended March 31, 2016. Under guidelines established by the SEC, companies are allowed to exclude acquisitions from their first assessment of internal control over financial reporting following the date of acquisition.
Triumph's independent registered public accounting firm, Ernst & Young LLP, has audited Triumph's effectiveness of Triumph's internal control over financial reporting. This report appears on the following page.
