Table of Contents

government and the general industrial market for marine propulsion, power generation, and pump and compressor applications use these products. We have been building engines for over 115 years under the Fairbanks Morse Engine™ brand name and we have a large installed base of engines for which we supply aftermarket parts and service. We have been the U.S. Navy’s supplier of choice for medium-speed diesel engines and have supplied engines to the U.S. Navy for over 70 years.

Customers. Our Engine Products and Services segment sells its products and services to customers worldwide, including major shipyards, municipal utilities, institutional and industrial organizations, sewage treatment plants, nuclear power plants and offshore oil and gas platforms, with approximately 6% of sales delivered to customers outside the United States in 2012. We market our products through a direct sales force of engineers in North America and through independent agents worldwide. Our representative customers include Northrop Grumman, General Dynamics, Lockheed Martin, the U.S. Navy, the U.S. Coast Guard, Toshiba America Nuclear Energy Corp., and Exelon. In 2012, the largest customer accounted for approximately 25% of segment revenues.

Competition. Major competitors for our Engine Products and Services segment include MTU, Caterpillar Inc., and Wartsila Corporation. Price, delivery time, engineering and service support, and engine efficiency relating to fuel consumption and emissions drive competition.

Raw Materials and Components. Our Engine Products and Services segment purchases multiple ferrous and non-ferrous castings, forgings, plate stock and bar stock for fabrication and machining into engines. In addition, we buy a considerable amount of precision-machined engine components. We believe all of these raw materials and components are readily available from various suppliers, but may be subject to long and variable lead times.

Research and Development

The goal of our research and development effort is to strengthen our product portfolios for traditional markets while simultaneously creating distinctive and breakthrough products. We utilize a process to move product innovations from concept to commercialization, and to identify, analyze, develop and implement new product concepts and opportunities aimed at business growth.

We employ scientists, engineers and technicians throughout our operations to develop, design and test new and improved products. We work closely with our customers to identify issues and develop technical solutions. The majority of our research and development spending typically is directed toward the development of new sealing products for the most demanding environments, the development of truck and trailer fleet information systems, the development of bearing products and materials with increased load carrying capability and superior friction and wear characteristics, and the development of engine products to meet current and future emissions requirements while improving fuel efficiencies.

Backlog

At December 31, 2012, we had a backlog of orders valued at $288.9 million compared with $351.2 million at December 31, 2011. Approximately 16% of the backlog, almost exclusively at Fairbanks Morse Engine, is expected to be filled beyond 2013. Backlog represents orders on hand we believe to be firm. However, there is no certainty the backlog orders will result in actual sales at the times or in the amounts ordered. In addition, for most of our business, backlog is not particularly predictive of future performance because of our short lead times and some seasonality.

Quality Assurance

We believe product quality is among the most important factors in developing and maintaining strong, long-term relationships with our customers. In order to meet the exacting requirements of our customers, we maintain stringent standards of quality control. We routinely employ in-process inspection by using testing equipment as a process aid during all stages of development, design and production to ensure product quality and reliability. These include state-of-the-art CAD/CAM equipment, statistical process control systems, laser tracking devices, failure mode and effect analysis, and coordinate measuring machines. We are able to extract numerical quality control data as a statistical measurement of the quality of the parts being manufactured from our CNC machinery. In addition, we perform quality control tests on parts that we outsource. As a result, we are able to significantly reduce the number of defective parts and therefore improve efficiency, quality and reliability.

As of December 31, 2012, 46 of our manufacturing facilities were ISO 9000, QS 9000 and/or TS 16949 certified. Twenty-one of our facilities are ISO 14001 certified. OEMs are increasingly requiring these standards in lieu of individual certification procedures, and as a condition of awarding business.

Patents, Trademarks and Other Intellectual Property

We maintain a number of patents and trademarks issued by the U.S. and other countries relating to the name and design of our products and have granted licenses to some of these patents and trademarks. We routinely evaluate the need to protect new and existing products through the patent and trademark systems in the U.S. and other countries. We also have unpatented proprietary information, consisting of know-how and trade secrets relating to the design, manufacture and operation of our products and their use. We do not consider our business as a whole to be materially dependent on any particular patent, patent right, trademark, trade secret or license granted or group of related patents, patent rights, trademarks, trade secrets or licenses granted.

In general, we are the owner of the rights to the products that we manufacture and sell. However, we also license patented and other proprietary technology and processes from various companies and individuals in order to broaden our product offerings. We are dependent on the ability of these third parties to diligently protect their intellectual property rights. In several cases, the intellectual property licenses are integral to the manufacture of our products. For example, Fairbanks Morse Engine licenses technology from MAN Diesel and its subsidiaries for certain of the four-stroke reciprocating engines it produces. The term of the licenses varies by engine type, with one set of licenses currently in the process of being renewed through 2018, while licenses for the remaining engine types have terms, subject to potential renewal, expiring in 2018 or 2019. A loss of these licenses or a failure on the part of the licensor to protect its own intellectual property could reduce our revenues. These licenses are subject to renewal and it is possible we may not successfully renegotiate these licenses or they could be terminated for a material breach. If this were to occur, our business, financial condition, results of operations and cash flows could be adversely affected.

Employees and Labor Relations

We currently have approximately 4,500 employees worldwide in our continuing operations. Approximately 2,300 employees are located within the U.S., and approximately 2,200 employees are located outside the U.S., primarily in Europe, Canada and China. Approximately 14% of our U.S. employees are members of trade unions covered by three collective bargaining agreements with contract termination dates from August 2014 to January 2018. Union agreements relate, among other things, to wages, hours, and conditions of employment. The wages and benefits furnished are generally comparable to industry and area practices. Our deconsolidated subsidiaries, primarily GST LLC, have about 1,000 additional employees worldwide.

In addition to the risks stated elsewhere in this annual report, set forth below are certain risk factors that we believe are material. If any of these risks occur, our business, financial condition, results of operations, cash flows and reputation could be harmed. You should also consider these risk factors when you read “forward-looking statements” elsewhere in this report. You can identify forward-looking statements by terms such as “may,” “hope,” “will,” “could,” “should,” “expect,” “plan,” “anticipate,” “intend,” “believe,” “estimate,” “predict,” “potential” or “continue,” the negative of those terms or other comparable terms. Those forward-looking statements are only predictions and can be adversely affected if any of these risks occur.

Risks Related to Our Business

Certain of our subsidiaries filed petitions to resolve asbestos litigation.

The historical business operations of certain subsidiaries of our subsidiary, Coltec Industries Inc (“Coltec”), principally GST LLC and The Anchor Packing Company (“Anchor”), have resulted in a substantial volume of asbestos litigation in which plaintiffs have alleged personal injury or death as a result of exposure to asbestos fibers. Those subsidiaries manufactured and/or sold industrial sealing products, predominately gaskets and packing products, which contained encapsulated asbestos fibers. Anchor is an inactive and insolvent indirect subsidiary of Coltec. There is no remaining insurance coverage available to Anchor and it has no assets. Our subsidiaries’ exposure to asbestos litigation and their relationships with insurance carriers has been actively managed through another Coltec subsidiary, Garrison Litigation Management Group, Ltd. (“Garrison,” collectively with GST LLC and Anchor, “GST”). On the Petition Date, GST LLC, Anchor and Garrison filed voluntary petitions for reorganization under Chapter 11 of the United States Bankruptcy Code in the U.S. Bankruptcy Court for the Western District of North Carolina in Charlotte (the “Bankruptcy Court”) to address these claims. These subsidiaries have been deconsolidated from our financial statements since the Petition Date. The amount that will be necessary to fully and finally resolve the asbestos liabilities of these companies is uncertain. Several risks and uncertainties result from these filings that could have a material adverse effect on our business, financial condition, results of operations and cash flows. Those risks and uncertainties include the following:

For a further discussion of the filings and the asbestos exposure of our subsidiaries, see Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Overview and Outlook,” “– Contingencies – Asbestos” and “– Contingencies – Subsidiary Bankruptcy,” and Notes 18 and 19 to our Consolidated Financial Statements, included in this report.

Our business and some of the markets we serve are cyclical and distressed market conditions could have a material adverse effect on our business.

The markets in which we sell our products, particularly chemical companies, petroleum refineries, heavy-duty trucking, semiconductor manufacturing, capital equipment and the automotive

Table of Contents

industry, are, to varying degrees, cyclical and have historically experienced periodic downturns. Prior downturns have been characterized by diminished product demand, excess manufacturing capacity and subsequent erosion of average selling prices in these markets resulting in negative effects on our net sales, gross margins and net income. The recent recession affected our results of operations. A prolonged and severe downward cycle in our markets could have a material adverse effect on our business, financial condition, results of operations and cash flows.

We face intense competition that could have a material adverse effect on our business.

We encounter intense competition in almost all areas of our businesses. Customers for many of our products are attempting to reduce the number of vendors from which they purchase in order to reduce inventories. To remain competitive, we need to invest continuously in manufacturing, marketing, customer service and support and our distribution networks. We also need to develop new products to continue to meet the needs and desires of our customers. We may not have sufficient resources to continue to make such investments or maintain our competitive position. Additionally, some of our competitors are larger than we are and have substantially greater financial resources than we do. As a result, they may be better able to withstand the effects of periodic economic downturns. Certain of our products may also experience transformation from unique branded products to undifferentiated price sensitive products. This product commoditization may be accelerated by low cost foreign competition. Changes in the replacement cycle of certain of our products, including because of improved product quality or improved maintenance, may affect aftermarket demand for such products. Initiatives designed to distinguish our products through superior service, continuous improvement, innovation, customer relationships, technology, new product acquisitions, bundling with key services, long-term contracts or market focus may not be effective. Pricing and other competitive pressures could adversely affect our business, financial condition, results of operations and cash flows.

If we fail to retain the independent agents and distributors upon whom we rely to market our products, we may be unable to effectively market our products and our revenue and profitability may decline.

Our marketing success in the U.S. and abroad depends largely upon our independent agents’ and distributors’ sales and service expertise and relationships with customers in our markets. Many of these agents have developed strong ties to existing and potential customers because of their detailed knowledge of our products. A loss of a significant number of these agents or distributors, or of a particular agent or distributor in a key market or with key customer relationships, could significantly inhibit our ability to effectively market our products, which could have a material adverse effect on our business, financial condition, results of operations and cash flows.

Increased costs for raw materials, the termination of existing supply agreements or disruptions of our supply chain could have a material adverse effect on our business.

The prices for some of the raw materials we purchase increased in 2012. While we have been successful in passing along some or all of these higher costs, there can be no assurance we will be able to continue doing so without losing customers. Similarly, the loss of a key supplier or the unavailability of a key raw material could adversely affect our business, financial condition, results of operations and cash flows.

Reductions in the U.S. Navy’s requirements for engines offered by Fairbanks Morse Engine could materially adversely affect the results of our Engine Products and Services segment.

Sales of new engines to the U.S. Navy by our Engine Products and Services segment, which have been a significant component of that segment’s revenues, are based on the U.S. Navy’s long-term ship-building programs. We currently anticipate that the U.S. Navy’s requirements for new engines of this

11

Table of Contents

type are likely to decline, which decline may be exacerbated by any curtailment in military budgets affecting the U.S. Navy’s ship-building programs. Unless we are able to develop alternative markets for new engines, any such decline in demand from the U.S. Navy could materially adversely affect the results of our Engine Products and Services segment.

We have exposure to some contingent liabilities relating to discontinued operations, which could have a material adverse effect on our financial condition, results of operations or cash flows in any fiscal period.

We have contingent liabilities related to discontinued operations of our predecessors, including environmental liabilities and liabilities for certain products and other matters. In some instances we have indemnified others against those liabilities, and in other instances we have received indemnities from third parties against those liabilities.

Claims could arise relating to products or other matters related to our discontinued operations. Some of these claims could seek substantial monetary damages. For example, we could potentially be subject to the liabilities related to the firearms manufactured prior to March 1990 by Colt Firearms, a former operation of Coltec, for electrical transformers manufactured prior to May 1994 by Central Moloney, another former Coltec operation, and for environmental liabilities associated with the pre-1985 operations of Crucible Steel Corporation a/k/a Crucible, Inc., a majority owned subsidiary of Coltec until 1985. Coltec has ongoing obligations with regard to workers compensation, retiree medical and other retiree benefit matters associated with discontinued operations in connection with Coltec’s periods of ownership of those operations.

We have insurance, reserves, and funds held in trust to address these liabilities. However, if our insurance coverage is depleted, our reserves are not adequate, or the funds held in trust are insufficient, environmental and other liabilities relating to discontinued operations could have a material adverse effect on our financial condition, results of operations and cash flows.

We conduct a significant amount of our sales activities outside of the U.S., which subjects us to additional business risks that may cause our profitability to decline.

Because we sell our products in a number of foreign countries, we are subject to risks associated with doing business internationally. In 2012, we derived approximately 45% of our revenues from sales of our products outside of the U.S. Our international operations are, and will continue to be, subject to a number of risks, including:

12

Table of Contents

Any of these factors, individually or together, could have a material adverse effect on our business, financial condition, results of operations and cash flows.

Our operations outside the United States require us to comply with a number of United States and international regulations. For example, our operations in countries outside the United States are subject to the Foreign Corrupt Practices Act (the “FCPA”), which prohibits United States companies or their agents and employees from providing anything of value to a foreign official for the purposes of influencing any act or decision of these individuals in their official capacity to help obtain or retain business, direct business to any person or corporate entity, or obtain any unfair advantage. Our activities in countries outside the United States create the risk of unauthorized payments or offers of payments by one of our employees or agents that could be in violation of the FCPA, even though these parties are not always subject to our control. We have internal control policies and procedures and have implemented training and compliance programs with respect to the FCPA. However, we cannot assure that our policies, procedures and programs always will protect us from reckless or criminal acts committed by our employees or agents. In the event that we believe or have reason to believe that our employees or agents have or may have violated applicable anti-corruption laws, including the FCPA, we may be required to investigate or have outside counsel investigate the relevant facts and circumstances. Violations of the FCPA may result in severe criminal or civil sanctions, and we may be subject to other liabilities, which could negatively affect our business, operating results and financial condition.

We intend to continue to pursue international growth opportunities, which could increase our exposure to risks associated with international sales and operations. As we expand our international operations, we may also encounter new risks that could adversely affect our revenues and profitability. For example, as we focus on building our international sales and distribution networks in new geographic regions, we must continue to develop relationships with qualified local agents, distributors and trading companies. If we are not successful in developing these relationships, we may not be able to increase sales in these regions.

Failure to properly manage these risks could adversely affect our business, financial condition, results of operations and cash flows.

If we are unable to protect our intellectual property rights and knowledge relating to our products, our business and prospects may be negatively impacted.

We believe that proprietary products and technology are important to our success. If we are unable to adequately protect our intellectual property and know-how, our business and prospects could be negatively impacted. Our efforts to protect our intellectual property through patents, trademarks, service marks, domain names, trade secrets, copyrights, confidentiality, non-compete and nondisclosure agreements and other measures may not be adequate to protect our proprietary rights. Patents issued to third parties, whether before or after the issue date of our patents, could render our intellectual property less valuable. Questions as to whether our competitors’ products infringe our intellectual property rights or whether our products infringe our competitors’ intellectual property rights may be disputed. In addition, intellectual property rights may be unavailable, limited or difficult to enforce in some jurisdictions, which could make it easier for competitors to capture market share in those jurisdictions.

Our competitors may capture market share from us by selling products that claim to mirror the capabilities of our products or technology. Without sufficient protection nationally and internationally for

13

Table of Contents

our intellectual property, our competitiveness worldwide could be impaired, which would negatively impact our growth and future revenue. As a result, we may be required to spend significant resources to monitor and police our intellectual property rights.

We have made and expect to continue to make acquisitions, which could involve certain risks and uncertainties.

We expect to continue to make acquisitions in the future. Acquisitions involve numerous inherent challenges, such as properly evaluating acquisition opportunities, properly evaluating risks and other diligence matters, ensuring adequate capital availability and balancing other resource constraints. There are risks and uncertainties related to acquisitions, including: difficulties integrating acquired technology, operations, personnel and financial and other systems; unrealized sales expectations from the acquired business; unrealized synergies and cost savings; unknown or underestimated liabilities; diversion of management attention from running our existing businesses and potential loss of key management employees of the acquired business. In addition, internal controls over financial reporting of acquired companies may not be up to required standards. Our integration activities may place substantial demands on our management, operational resources and financial and internal control systems. Customer dissatisfaction or performance problems with an acquired business, technology, service or product could also have a material adverse effect on our reputation and business.

Our business could be materially adversely affected by numerous other risks, including rising healthcare costs, changes in environmental laws and unforeseen business interruptions.

Our business may be negatively impacted by numerous other risks. For example, medical and healthcare costs may continue to increase. Initiatives to address these costs, such as consumer driven health plan packages, may not successfully reduce these expenses as needed. Failure to offer competitive employee benefits may result in our inability to recruit or maintain key employees. Other risks to our business include potential changes in environmental rules or regulations, which could negatively impact our manufacturing processes. Use of certain chemicals and other substances could become restricted or such changes may otherwise require us to incur additional costs which could reduce our profitability and impair our ability to offer competitively priced products. Additional risks to our business include global or local events which could significantly disrupt our operations. Terrorist attacks, natural disasters, political insurgencies, pandemics, information system failures, cybersecurity breaches, and electrical grid disruptions and outages are some of the unforeseen risks that could negatively affect our business, financial condition, results of operations and cash flows.

Risks Related to Ownership of Our Common Stock

The market price and trading volume of our common stock may be volatile.

A relatively small number of shares traded in any one day could have a significant effect on the market price of our common stock. The market price of our common stock could fluctuate significantly for many reasons, including in response to the risks described in this section and elsewhere in this report or for reasons unrelated to our operations, such as reports by industry analysts, investor perceptions or negative announcements by our customers, competitors or suppliers regarding their own performance, as well as industry conditions and general financial, economic and political instability.

Because our quarterly revenues and operating results may vary significantly in future periods, our stock price may fluctuate.

Our revenue and operating results may vary significantly from quarter to quarter. A high proportion of our costs are fixed, due in part to significant selling and manufacturing costs. Small

14

Table of Contents

declines in revenues could disproportionately affect operating results in a quarter and the price of our common stock may fall. We may also incur charges to income to cover increases in the estimate of our subsidiaries’ future asbestos liability. Other factors that could affect quarterly operating results include, but are not limited to:

Various provisions and laws could delay or prevent a change of control.

The anti-takeover provisions of our articles of incorporation and bylaws, our shareholder rights plan and provisions of North Carolina law could delay or prevent a change of control or may impede the ability of the holders of our common stock to change our management. In particular, our articles of incorporation and bylaws, among other things:

15

Table of Contents

Future sales of our common stock in the public market could lower the market price for our common stock and adversely impact the trading price of our convertible debentures.

In the future, we may sell additional shares of our common stock to raise capital. In addition, a reasonable number of shares of our common stock are reserved for issuance under our equity compensation plans, including shares to be issued upon the exercise of stock options, vesting of restricted stock or unit grants, and upon conversion of our convertible debentures. We cannot predict the size of future issuances or the effect, if any, that they may have on the market price for our common stock. The issuance and sales of substantial amounts of common stock, or the perception that such issuances and sales may occur, could adversely affect the trading price of the debentures and the market price of our common stock.

Absence of dividends could reduce our attractiveness to investors.

We have never declared or paid cash dividends on our common stock. Moreover, our current senior secured credit facility restricts our ability to pay cash dividends on common stock if availability under the facility falls below $20 million. As a result, our common stock may be less attractive to certain investors than the stock of companies with a history of paying regular dividends.

Risks Related to Our Capital Structure

Our debt agreement imposes limitations on our operations, which could impede our ability to respond to market conditions, address unanticipated capital investments and/or pursue business opportunities.

We have a senior secured revolving credit facility that imposes limitations on our operations, such as limitations on distributions, limitations on incurrence and repayment of indebtedness, and maintenance of a fixed charge coverage financial ratio if average monthly availability is less than certain thresholds. These limitations could impede our ability to respond to market conditions, address unanticipated capital investment needs and/or pursue business opportunities.

We may not have sufficient cash to fund amounts payable upon a conversion of our convertible debentures or to repurchase the debentures at the option of the holder upon a change of control.

Our convertible debentures mature on October 15, 2015. The debentures are subject to conversion when one or more of the conversion conditions specified in the indenture governing the debentures are satisfied. Upon a conversion, we will be required to make a cash payment of up to $1,000 for each $1,000 in principal amount of debentures converted. One of these conversion conditions is based on the trading price of our common stock. The debentures become subject to conversion in the succeeding quarter, upon notice by the holders, when the closing price per share of our common stock exceeds $43.93, or 130% of the conversion price of $33.79, for at least twenty (20) trading days during

16

Table of Contents

the last thirty (30) consecutive trading days of any calendar quarter (such amounts are subject to adjustment for specified events as set forth in the indenture). None of the conversion conditions were satisfied at December 31, 2012, but this particular condition was met during the quarter ended June 30, 2011. No debentures were converted during the subsequent quarter ended September 30, 2011.

In addition, upon a change of control, subject to certain conditions, we will be required to make an offer to repurchase for cash all outstanding convertible debentures at 100% of their principal amount plus accrued and unpaid interest, including liquidated damages, if any, up to but not including the date of repurchase. However, we may not have enough available cash or be able to obtain financing at the time we are required to settle converted debentures or make repurchases of tendered debentures. Any credit facility in place at the time of a repurchase or conversion of the debentures may also limit our ability to use borrowings to pay any cash payable on a repurchase or conversion of the debentures and may prohibit us from making any cash payments on the repurchase or conversion of the debentures if a default or event of default has occurred under that facility without the consent of the lenders under that credit facility. Our current $175 million senior secured credit facility prohibits distributions from our subsidiaries to us to make payments of principal or interest on the debentures or payments upon conversion of the debentures and prohibits prepayments of the debentures, in each case if a default or event of default exists or if our subsidiaries identified as borrowers under the facility fail to have either (a) pro forma average borrowing availability under the facility greater than the greater of (i) the lesser of 25% of (A) the available borrowing base or (B) the aggregate commitments of the lenders under the credit facility or (ii) $20 million or (b) (i) pro forma average borrowing availability under the facility greater than the greater of (A) the lesser of 20% of (I) the available borrowing base or (II) the aggregate commitments of the lenders under the credit facility or (B) $17.5 million, and (ii) a pro forma fixed charge coverage ratio that is greater than 1.0 to 1.0. Our failure to repurchase tendered debentures at a time when the repurchase is required by the indenture or to pay any cash payable on a conversion of the debentures would constitute a default under the indenture. A default under the indenture or the change of control itself could lead to a default under the other existing and future agreements governing our indebtedness. If the repayment of the related indebtedness were to be accelerated after any applicable notice or grace periods, we may not have sufficient funds to repay the indebtedness and repurchase the debentures or make cash payments upon conversion thereof.

Derivative transactions may expose us to unexpected risk and potential losses.

We are party to certain derivative transactions, such as foreign exchange forward contracts and call options (hedge and warrant transactions) with respect to our convertible debentures, with financial institutions to hedge against certain financial risks. In light of current economic uncertainty and potential for financial institution failures, we may be exposed to the risk that our counterparty in a derivative transaction may be unable to perform its obligations as a result of being placed in receivership or otherwise. In the event a counterparty to a material derivative transaction is unable to perform its obligations thereunder, we may experience losses material to our results of operations and financial condition.

Not applicable.

We are headquartered in Charlotte, North Carolina and have 61 primary manufacturing facilities in 12 countries, including the U.S. The following table outlines the location, business segment and size of our largest facilities, along with whether we own or lease each facility:

Our manufacturing capabilities are flexible and allow us to customize the manufacturing process to increase performance and value for our customers and meet particular specifications. We also maintain numerous sales offices and warehouse facilities in strategic locations in the U.S., Canada and other countries. We believe our facilities and equipment are generally in good condition and are well maintained and able to continue to operate at present levels.

The following is management’s discussion and analysis of certain significant factors that have affected our consolidated financial condition and operating results during the periods included in the accompanying audited Consolidated Financial Statements and the related notes. You should read the following discussion in conjunction with our audited Consolidated Financial Statements and the related notes, included elsewhere in this annual report.

Forward-Looking Statements

This report contains certain statements that are “forward-looking statements” as that term is defined under the Private Securities Litigation Reform Act of 1995 (the “Act”) and releases issued by the Securities and Exchange Commission (the “SEC”). The words “may,” “hope,” “will,” “should,” “could,” “expect,” “plan,” “anticipate,” “intend,” “believe,” “estimate,” “predict,” “potential,” “continue,” and other expressions which are predictions of or indicate future events and trends and which do not relate to historical matters identify forward-looking statements. We believe that it is important to communicate our future expectations to our shareholders, and we therefore make forward-looking statements in reliance upon the safe harbor provisions of the Act. However, there may be events in the future that we are not able to accurately predict or control, and our actual results may differ materially from the expectations we describe in our forward-looking statements.

Overview and Outlook

Overview. We design, develop, manufacture, service and market proprietary engineered industrial products. We have 61 primary manufacturing facilities located in 12 countries, including the United States.

We manage our business as three segments: a Sealing Products segment, an Engineered Products segment, and an Engine Products and Services segment.

Our Sealing Products segment designs, manufactures and sells sealing products, including: metallic, non-metallic and composite material gaskets; dynamic seals; compression packing; resilient metal seals; elastomeric seals; hydraulic components; expansion joints; heavy-duty truck wheel-end component systems, including brake products; flange sealing and isolation products; pipeline casing spacers/isolators; casing end seals; modular sealing systems for sealing pipeline penetrations; hole forming products; manhole infiltration sealing systems; safety-related signage for pipelines; bellows and bellows assemblies; pedestals for semiconductor manufacturing; PTFE products; conveyor belting; and sheeted rubber products. These products are used in a variety of industries, including chemical and petrochemical processing, petroleum extraction and refining, pulp and paper processing, heavy-duty trucking, power generation, food and pharmaceutical processing, primary metal manufacturing, mining, water and waste treatment, aerospace, medical, filtration and semiconductor fabrication. In many of these industries, performance and durability are vital for safety and environmental protection. Many of our products are used in applications that are highly demanding, e.g., where extreme temperatures, extreme pressures, corrosive environments, strict tolerances, and/or worn equipment make product performance difficult.

Our Engineered Products segment includes operations that design, manufacture and sell self-lubricating, non-rolling, metal-polymer, solid polymer and filament wound bearing products, aluminum blocks for hydraulic applications and precision engineered components and lubrication systems for reciprocating compressors. These products are used in a wide range of applications, including the automotive, pharmaceutical, pulp and paper, natural gas, health, power generation, machine tools, air treatment, refining, petrochemical and general industrial markets.

Our Engine Products and Services segment designs, manufactures, sells and services heavy-duty, medium-speed diesel, natural gas and dual fuel reciprocating engines. The United States government and the general markets for marine propulsion, power generation, and pump and compressor applications use these products and services.

The historical business operations of certain subsidiaries of our subsidiary, Coltec Industries Inc (“Coltec”), principally Garlock Sealing Technologies LLC (“GST LLC”) and The Anchor Packing Company (“Anchor”), have resulted in a substantial volume of asbestos litigation in which plaintiffs have alleged personal injury or death as a result of exposure to asbestos fibers. Information about GST LLC’s asbestos litigation is contained in this Management’s Discussion and Analysis of Financial Condition and Results of Operations in the “Asbestos” subsection of the “Contingencies” section.

On June 5, 2010 (the “Petition Date”), GST LLC, Anchor and Garrison Litigation Management Group, Ltd. (“Garrison”) filed voluntary petitions for reorganization under Chapter 11 of the United States Bankruptcy Code in the U.S. Bankruptcy Court for the Western District of North Carolina in Charlotte (the “Bankruptcy Court”). GST LLC, Anchor and Garrison are sometimes referred to collectively as “GST” in this report. The filings were the initial step in a claims resolution process. GST LLC is one of the businesses in our broader Garlock group. GST LLC and its subsidiaries operate five significant manufacturing facilities, including operations in Palmyra, New York and Houston, Texas. The filings did not include EnPro Industries, Inc., or any other EnPro Industries, Inc. operating subsidiary.

GST LLC now operates in the ordinary course under court protection from asbestos claims. All pending litigation against GST is stayed during the process. We address our actions to permanently resolve GST LLC’s asbestos litigation in this Management’s Discussion and Analysis of Financial Condition and Results of Operations in the “Garlock Sealing Technologies LLC and Garrison Litigation Management Group, Ltd.” section.

The financial results of GST and subsidiaries are included in our consolidated results through June 4, 2010, the day prior to the Petition Date. However, U.S. generally accepted accounting principles require an entity that files for protection under the U.S. Bankruptcy Code, whether solvent or insolvent, whose financial statements were previously consolidated with those of its parent, as GST’s and its subsidiaries’ were with ours, generally must be prospectively deconsolidated from the parent and the investment accounted for using the cost method. At deconsolidation, our investment was recorded at its estimated fair value as of June 4, 2010, resulting in a gain for reporting purposes. The cost method requires us to present our ownership interests in the net assets of GST at the Petition Date as an investment and not recognize any income or loss from GST and subsidiaries in our results of operations during the reorganization period. Our investment of $236.9 million as of December 31, 2012 and 2011, was subject to periodic reviews for impairment. When GST emerges from the jurisdiction of the Bankruptcy Court, the subsequent accounting will be determined based upon the applicable facts and circumstances at such time, including the terms of any plan of reorganization. See Note 18 to the Consolidated Financial Statements in this Form 10-K for condensed financial information of GST and subsidiaries.

During 2012, 2011, and 2010, we completed a number of acquisitions and a disposition of a business. Please refer to “Acquisitions and Dispositions” in Item 1 – Business for additional discussion regarding these transactions.

We completed our required annual impairment test of goodwill as of October 1, 2012. The estimated fair value of our CPI reporting unit, included in our Engineered Products segment, exceeded its book value by 10% and 37% in 2012 and 2011, respectively. There is $55.4 million of goodwill allocated to CPI. The fair value of the CPI reporting unit was calculated using both discounted cash flow and market valuation approaches. The key assumptions used for the discounted cash flow approach include business projections, growth rates, and a discount rate of 10.3%. The discount rate we use is based on our weighted average cost of capital. For the market approach, we chose a group of 14 companies we believe are representative of our diversified industrial peers. We used a 70% weighting for the discounted cash flow valuation approach and a 30% weighting for the market valuation approach, reflecting our belief that the discounted cash flow valuation approach provides a better indicator of value since it reflects the specific cash flows anticipated to be generated in the future by the business. For sensitivity purposes, a 100-basis-point increase in the discount rate would result in this reporting unit exceeding its 2012 book value by 2%. Conversely, a 100-basis-point decrease in the discount rate would result in this reporting unit exceeding its 2012 book value by 21%.

The future cash flows modeled for CPI are dependent on certain cost savings restructuring initiatives and a customer-focused organizational realignment, both launched in 2012. Non-recurring restructuring expenses in 2012 were $2.3 million. In addition, approximately $5.5 million of 2012 labor and facilities cost was removed from our future cost structure. The customer-focused organizational realignment during 2012 was critical to price and volume opportunities identified while developing the 2013 forecast. While there is uncertainty associated with the customer price and volume opportunities, only a portion of these opportunities were forecasted in the future cash flow model utilized for goodwill impairment testing.

Finally, we are dependent on the strength of our customers and their respective industries to achieve sales forecasted for 2013. Except for 2013, which is based on a detailed forecast, the remaining years in the cash flow model are based on the 2013 forecast, adjusted for assumed macro-economic forecasts for Industrial Production changes at each of our major geographic markets per the DuPont Economic outlook as of September 2012. Since our products serve a variety of industries, Industrial Production is a good indicator for demand changes for our products and services. The nominal growth rates for 2014 and beyond, are approximately 6%, 3%, and 15% for North America, Europe, and Asia, respectively.

Management believes that all assumptions used were reasonable based on historical operating results and expected future trends. However, if future operating results are unfavorable as compared with forecasts, the results of future goodwill impairment evaluations could be negatively affected.

We determined all other reporting units had fair values substantially in excess of carrying values and there were no subsequent indicators of impairment through December 31, 2012.

Outlook

Although there are indications our markets may improve in the second half of 2013, we expect conditions encountered in the second half of 2012 to persist into the first half of 2013. In the first quarter of 2013, we expect sales and segment profit to be less than they were in the first quarter of 2012, when activity in our markets and demand for our products were significantly above current levels. Sales will benefit from the inclusion of Motorwheel in the first quarter; however, we anticipate that benefit will be more than offset by soft demand from the markets served by the Sealing Products and Engineered Products segments and lower sales in the Engine Products and Services segment. Since we do not currently anticipate shipping any engines under the completed contract revenue recognition method in the first quarter of 2013, we expect Engine Products and Services sales to be 25% to 30% below the first quarter of 2012, when four engines were shipped under the completed contract revenue recognition method. We expect segment profit margins in the first quarter of 2013 will reflect lower volumes and a less profitable product mix in the Sealing Products segment.

We believe conditions may improve in our industrial markets by the second half of 2013. However, we anticipate any growth in sales to those markets will be offset by a decline in full year sales in the Engine Products and Services segment. Although we currently expect the segment to ship a higher number of engines in 2013 than was shipped in 2012, revenues for these engines will be recognized only under percentage of completion accounting. We expect the segment’s full year 2013 sales to decline by about 15% in comparison to 2012.

Our effective tax rate is directly affected by the relative proportions of revenue and income before taxes in the jurisdictions in which we operate. Based on the expected mix of domestic and foreign earnings, we anticipate our effective tax rate to remain lower than the U.S. statutory rate primarily due to the earnings in lower rate foreign jurisdictions. In the U.S., we benefit from certain tax incentives such as the deduction for domestic production activities, and credits for research and development. Discrete tax events may cause our effective rate to fluctuate on a quarterly basis. Certain events, including, for example, acquisitions and other business changes, which are difficult to predict, may also cause our effective tax rate to fluctuate. We are subject to changing tax laws, regulations, and interpretations in multiple jurisdictions. Corporate tax reform continues to be a priority in the U.S. and other jurisdictions. Changes to the tax system in the U.S. could have significant effects, positive and negative, on our effective tax rate, and on our deferred tax assets and liabilities.

In January 2013, the United States Congress passed the American Taxpayer Relief Act of 2012 which retroactively extended various tax provisions applicable to the Company. As a result, we expect

28

Table of Contents

that our income tax provision for the first quarter of 2013 will include a tax benefit which will significantly reduce our effective tax rate for the quarter and to a lesser extent the annual effective tax rate for 2013.

The IRS completed the field examination for our 2008, 2009, and 2010 U.S. federal income tax returns during the third quarter of 2012, which resulted in incremental taxes payable of $1.5 million and tax expense of $1.4 million. As a result of the IRS’s conclusion of its field examination, we reduced our liability for uncertain tax positions by $2.4 million to reflect amounts determined to be effectively settled, which lowered income tax expense by $1.9 million. Finally, we recorded $1.2 million of additional income tax expense related to the 2011 tax return filed in the third quarter of 2012. Although the IRS fieldwork was completed with respect to the 2008, 2009, and 2010 tax returns, we disagreed with and protested certain adjustments included in the audit results. While these audit years remain open, the only items under appeal that are not considered to be effectively settled relate to our deconsolidated GST operations. No further recognition of income tax expense or benefit to the Company’s results is expected, however, should there ultimately be an assessment against the combined tax group the Company would be responsible for payment and then seek a reimbursement from GST, which may be classified as a noncurrent receivable. The Company believes the position will be sustained, and the entire as-filed tax return amount has been recognized. Should the position be lost, additional taxes of approximately $39.5 million, plus potential interest and penalties, would become payable.

Our U.S. defined benefit plans continue to be underfunded. Based on currently available data, which is subject to change, we estimate we will be required to make contributions to the U.S. defined benefit plans in 2013 totaling approximately $19.1 million. We expect 2013 contributions to non-U.S. defined benefit plans to be insignificant. Additional significant cash contributions to the U.S. defined benefit plans are likely to be required in 2014 and beyond. Future contribution requirements depend on pension asset returns, pension valuation assumptions, plan design, and legislative actions. In July 2012, the President signed the Moving Ahead for Progress in the 21^st Century Act (MAP-21). Although MAP-21 reduced short-term minimum pension contribution requirements in 2012 and 2013, we expect additional significant cash contributions to be required in 2014 and beyond. We estimate that annual GAAP pension expense in 2013 will be $11.1 million, which is $1.3 million less than in 2012. The decrease in pension expense is primarily due to the strong performance of the pension assets, partially offset by a decrease in the discount rate used in the actuarial computations.

In connection with our growth strategy, we will continue to evaluate acquisitions in 2013; however, the effect of such acquisitions cannot be predicted and therefore is not reflected in this outlook.

We address our outlook on our actions to permanently resolve GST LLC’s asbestos litigation in this “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Garlock Sealing Technologies LLC and Garrison Litigation Management Group, Ltd.” section.

Results of Operations

The following table does not include results for GST and subsidiaries after the day preceding the Petition Date. See Note 18 to our Consolidated Financial Statements in this Form 10-K for condensed financial information for GST and subsidiaries.

Segment profit is total segment revenue reduced by operating, restructuring and other expenses identifiable with the segment. Corporate expenses include general corporate administrative costs. Expenses not directly attributable to the segments, corporate expenses, net interest expense, asbestos-related expenses, gains/losses or impairments related to the sale of assets, and income taxes are not included in the computation of segment profit. The accounting policies of the reportable segments are the same as those for EnPro.

2012 Compared to 2011

Sales of $1,184.2 million in 2012 increased 7% from $1,105.5 million in 2011. The following table illustrates the effects of key factors resulting in the change in sales by segment:

Following are key points regarding changes in sales for 2012 compared to 2011:

30

Table of Contents

Segment profit, management’s primary measure of how our operations perform, increased 5% to $148.5 million in 2012 from $141.0 million in 2011. Earnings from acquisitions contributed $9.0 million while selected price increases generated $13.4 million. These favorable changes were partially offset by unfavorable foreign exchange fluctuations of $3.2 million, an increase in restructuring costs of $3.6 million, volume reductions of $4.4 million and higher SG&A costs.

Corporate expenses for 2012 declined by $0.3 million compared to 2011. The decline was driven by a decrease in employee incentive compensation of $3.1 million, offset by higher consulting and management expenses of $1.9 million and higher directors’ share-based compensation of $0.9 million.

Net interest expense in 2012 was $42.8 million compared to $39.6 million in 2011. The increase in net interest expense was caused primarily by higher borrowings on the senior secured revolving credit facility.

Other expense, net in 2012 was $9.9 million compared to $3.8 million in 2011. The increase was caused primarily by a $2.9 million gain recorded on the guaranteed investment contract (“GIC”) in 2011 and a current year increase in environmental-related expenses of $1.2 million and in our expenses associated with GST’s bankruptcy proceedings of $0.5 million as compared to 2011. Refer to Note 19, “Commitments and Contingencies – Crucible Steel Corporation a/k/a Crucible, Inc.” in our Consolidated Financial Statements in this Form 10-K for additional information about the GIC and the Crucible Back-Up Trust.

Income tax expense in 2012 was $22.5 million compared to $20.8 million reported in 2011. The increase in tax expense reflects an increase in the effective tax rate to 35.3% in 2012 from 32.1% in 2011, when applied to comparable pre-tax income in both periods. In the U.S., we historically have benefited from federal income tax incentives such as the deduction for domestic production activities and credits for research and development. However, as of December 31, 2012, certain tax incentives expired and were not renewed before the end of 2012. These include the research and experimentation credit, certain employment credits, and an exclusion for passive income earned by controlled foreign corporations. In January 2013, the United States Congress passed the American Taxpayer Relief Act (ATRA) of 2012 which retroactively extended these tax provisions. The effective tax rate above reflects the tax law that was in place as of December 31, 2012. Had the ATRA been enacted prior to January 1, 2013, our overall tax expense would have been approximately $20.9 million, resulting in an overall effective tax rate of 32.7%. This $1.6 million difference will be reflected in tax expense during the first quarter of 2013.

Income from continuing operations was $41.0 million, or $1.90 per share, in 2012 compared to $44.2 million, or $2.06 per share, in 2011. Earnings per share are expressed on a diluted basis.

Following is a discussion of operating results for each segment during the year:

Sealing Products. Sales of $609.1 million in 2012 were 14% higher than the $534.9 million reported in 2011. The increase in sales includes 15 percentage points due to the acquisitions of Tara ($41.7 million), Motorwheel ($33.0 million), and PSI ($6.8 million) and one percentage point due to price

31

Table of Contents

increases. These increases were partially offset by a two percentage point decline in sales due to unfavorable foreign currency exchange rates.

Segment profit increased to $88.8 million in 2012 from $81.2 million in 2011. Acquisitions contributed $9.0 million toward the increase in segment profit, primarily due to Tara ($4.4 million) and Motorwheel ($4.2 million) and selected net price increases contributed $8.4 million. These increases were partially offset by unfavorable foreign currency fluctuations of $1.7 million and an unfavorable change in volume and mix of $5.2 million. Selling, general, and administrative costs increased by $2.7 million, driven mainly by increased payroll costs and travel. Operating margins for the segment declined to 14.6% in 2012 from 15.2% in 2011.

Engineered Products. Sales of $363.0 million in 2012 were 6% lower than the $386.7 million reported in 2011. Sales volumes were down a net six percentage points due primarily to declines in European automotive and industrial manufacturing segments at GGB and continued weak demand at CPI in European industrial and refining markets and in certain North American markets, including the natural gas region of Western Canada; these unfavorable changes in sales were partially offset by improvements in China and Australia. Unfavorable foreign exchange rates hurt segment sales by four percent, or $16.1 million. The acquisitions of PI Bearings ($6.3 million) and Mid Western ($3.5 million) in 2011 favorably affected 2012 sales by 2 percentage points. Selected price increases also contributed two percent to segment sales.

Segment profit in 2012 was $20.5 million, down by $8.7 million from $29.2 million in 2011. Segment profit was negatively impacted by $10.2 million, primarily as a result of a decline in sales volumes. In addition, increased restructuring costs of $3.4 million and unfavorable foreign exchange rate fluctuations of $1.6 million, as compared to 2011, were also unfavorable to segment profit. Selected price increases, net of higher costs, contributed $3.7 million to segment profit and decreases in selling, general, and administrative costs contributed an additional $2.8 million to segment profits. Operating margins for the segment were 5.6% in 2012, which declined from the 7.6% reported last year.

Engine Products and Services. Sales increased 15% to $214.6 million in 2012 from $185.8 million in 2011, due primarily to an increase in engine revenue of eight percent. Although 14 engines were shipped in each year, revenue for eight of the engines shipped in 2012 was recognized over the past 18 months under percentage of completion accounting, which began in the third quarter of 2011 for new engine programs. Revenues for six engines shipped in 2012 and all engines shipped in 2011 were accounted for under the completed contract method. Sales of aftermarket parts in the government and nuclear generation industries contributed six percentage points to the increased sales. New environmental upgrade products, developed in late 2011, generated two percent in additional sales, partially offset by lower service revenue.

The segment reported a profit of $39.2 million in 2012 compared to $30.6 million in 2011. Segment profit improved by $6.6 million due to higher engine revenue. In addition, the segment recorded a $1.4 million estimated warranty expense in 2011 to repair a specific engine component in a series of U.S. Navy ships. The segment also recorded a $3.0 million estimated loss on an engine contract in 2011. These large costs during 2011 were partly offset by benefits booked in the same period of 2011 related to reimbursements on the canceled South Texas Project (nuclear business) of $1.8 million and the favorable resolution of a legal matter amounting to $0.5 million. Operating margins increased to 18.3% in 2012 from 16.5% in 2011.

2011 Compared to 2010

Sales of $1,105.5 million in 2011 increased 28% from $865.0 million in 2010. The following table illustrates the effects of key factors resulting in the change in sales by segment:

32

Table of Contents

Sales from acquisitions completed in 2010 and 2011 contributed about 20 percentage points to the increase. In addition, sales increased as a result of higher volumes in the Sealing Products and Engineered Products segments as we captured improvements in 2011 in nearly all of our customer markets. Selected price increases we instituted in 2011 also contributed to the increase in sales compared to 2010. Sales in the Engine Products and Services segment grew 12% primarily due to shipping more engines, with higher average revenue per engine, and incremental revenue related to using the percentage-of-completion accounting method beginning in the third quarter of 2011. Changes in foreign exchange rates added two percentage points to the sales increase. Sales in 2010 included GST LLC through the Petition Date while sales in 2011 excluded GST LLC’s sales for the full year as a result of the deconsolidation of GST LLC effective on the Petition Date. Sales from GST LLC to third parties in 2010 through the Petition Date were $77.7 million.

Segment profit, management’s primary measure of how our operations perform, increased 15% to $141.0 million in 2011 from $122.1 million in 2010. Earnings from acquisitions completed in 2010 and 2011 contributed about six percentage points to the improvement. Segment profit also increased due to the higher volumes in the Sealing Products and Engineered Products segments, especially in Engineered Products, while price increases in these segments essentially offset net cost increases in 2011 compared to 2010. These year-over-year improvements were reduced by the deconsolidation of GST LLC effective on the Petition Date. Segment profit in 2010 included GST LLC through the Petition Date while segment profit in 2011 excluded GST LLC’s operating income for the full year as a result of the deconsolidation of GST LLC effective on the Petition Date. Segment profit for GST LLC in 2010 through the Petition Date was $14.0 million.

The improvements in the Sealing Products and Engineered products segments were partially offset by the decline in earnings in the Engine Products and Services segment caused by lower margins on the higher engine shipments, a decrease in higher margin parts and services revenue, and provisions for a warranty matter and an anticipated contract loss. Segment operating margins were lower also due to the inclusion of acquired businesses with lower than average margins as compared to the other businesses in the segment. Changes in foreign exchange rates added two percentage points to the segment profit increase. As a result of these changes, segment margins, defined as segment profit divided by sales, declined from 14.1% in 2010 to 12.8% in 2011. Excluding the Engine Parts and Services segment, segment margins declined only slightly from 12.4% in 2010 to 12.0% in 2011.

Corporate expenses for 2011 declined by $4.1 million compared to 2010 primarily due to lower medical expenses, directors’ share-based compensation, and consulting expenses partially offset by higher salary and management’s incentive compensation expenses.

Net interest expense in 2011 was $39.6 million compared to $25.9 million in 2010. The increase in net interest expense was caused primarily by the deconsolidation of GST and the inclusion of interest expense on notes payable to GST LLC in our results, which previously was eliminated in our consolidated results. We also incurred interest expense in 2011 on new borrowings on the senior secured revolving credit facility.

33

Table of Contents

Due to the deconsolidation of GST, asbestos-related expenses during 2011 were zero, which represented a decrease of $23.3 million compared to 2010.

Other income (expense), net in 2011 includes the $2.9 million gain recorded upon the contribution of the GIC from the Crucible Back-Up Trust to our defined benefit plan assets. In connection with the deconsolidation of GST, we recorded a pre-tax gain of $54.1 million in 2010. The gain is discussed in the “Garlock Sealing Technologies LLC and Garrison Litigation Management Group, Ltd.” section of this Management’s Discussion and Analysis of Financial Condition and Results of Operations.

We recorded an income tax expense of $20.8 million on pre-tax income from continuing operations of $65.0 million in 2011, resulting in an effective tax rate of 32.1%. Our effective tax rate in 2011 was lower than the U.S. statutory rates, primarily due to the earnings in lower rate foreign jurisdictions. In the U.S., we also benefited from certain tax incentives such as the deduction for domestic production activities and credits for research and development. During 2010, our effective tax rate was 25.8% as we recorded an income tax expense of $21.3 million on pre-tax income from continuing operations of $82.6 million. The income tax expense in 2010 was favorably affected by the restructuring of part of our GGB operation in Europe, as well as the overall jurisdictional mix of earnings.

Income from continuing operations was $61.3 million, or $2.96 per share, in 2010 compared to $44.2 million, or $2.06 per share, in 2011. Earnings per share are expressed on a diluted basis.

Net income for 2011 was the same as income from continuing operations. Including discontinued operations, which only affected our 2010 results, net income was $155.4 million in 2010, or $7.51 per share. Earnings per share are expressed on a diluted basis.

Following is a discussion of operating results for each segment during the year:

Sealing Products. Sales of $534.9 million in 2011 were 35% higher than the $397.6 million reported in 2010. The increase in sales included 33 percentage points due to the acquisitions of PSI ($60.7 million), Tara ($28.6 million), and Rome Tool & Die ($42.4 million). Increases in volume, reflecting improved markets and increased market share, plus selected net price increases since 2010 were essentially offset by the sales decrease caused by the deconsolidation of GST. Sales from GST LLC to third parties in 2010 through the Petition Date were $77.7 million. The consolidated Garlock operations experienced improved demand in several markets including oil and gas, and rubber products, and in Europe and Asia. Technetics Group demand was higher in 2011 in most markets and in several product lines. Stemco reported large increases in OEM (about 50%), brake products (about 95%), and aftermarket demand (about 10%) and prices increased about 4%. Favorable foreign exchange rates contributed about two percentage points to the sales increase.

Segment profit of $81.2 million in 2011 increased 16% compared to the $70.3 million reported in 2010. Despite higher volumes, some contribution from the acquisitions, and price increases, which nearly offset all cost increases, Garlock earnings declined because of the deconsolidation of GST LLC effective on the Petition Date. Segment profit for GST LLC in 2010 through the Petition Date was $14.0 million. Earnings at Technetics increased in 2011 compared to 2010, but the increase was less than the improvement in sales because of lower incremental earnings at the acquired businesses. Stemco reported an increase in profit in connection with its higher volumes, including its acquired business, which was reduced by cost increases in excess of selected price increases in 2011. Operating margins for the Stemco brake products acquisition in 2011 were lower than the historical business. Operating margins for the segment decreased to 15.2% in 2011 from 17.7% in 2010.

Table of Contents

Engineered Products. Sales of $386.7 million in 2011 were 28% higher than the $302.5 million reported in 2010. The increase in sales included 13 percentage points due to the acquisitions of CC Technology, Progressive Equipment, and Premier Lubrication Systems ($16.4 million), Mid Western ($17.8 million) and PI Bearing Technologies ($4.2 million). In addition, sales for GGB and CPI in 2011 increased $26.0 million as both operations continued to capture higher volume from improvements in several markets and $7.9 million due to selected price increases. Favorable foreign exchange rates contributed $12.6 million or four percentage points to the segment’s sales growth.

The segment profit in 2011 was $29.2 million, which was 79% higher than the $16.3 million reported in 2010. Increased profits at GGB and CPI came primarily from higher volumes of $9.8 million and selected price increases of $7.9 million, partially offset by cost increases of $6.2 million in materials and SG&A. Acquisitions completed in 2010 and 2011 added $0.7 million to the increase and changes in foreign exchange rates added $1.7 million. Operating margins for the segment were 7.6% in 2011, which improved from the 5.4% reported in 2010.

Engine Products and Services. Sales increased 12% from $166.0 million in 2010 to $185.8 million in 2011. Sales increased $29.0 million due to shipping 14 engines in 2011 versus 12 engines in 2010, with a higher average price per engine in 2011 due to the types of engines shipped. Additionally, the Engine Products and Services segment also recognized incremental revenue of $9.6 million related to using the percentage-of-completion accounting method for new or nearly new engine programs beginning in the third quarter of 2011. These increases were partially offset by a decline in parts and services revenue in 2011.

The segment reported a profit of $30.6 million in 2011 compared to $35.5 million in 2010. A lower margin mix of engine shipments in 2011, the decrease in higher margin aftermarket parts and services activity, and net cost increases contributed to the decrease in segment profit. In addition, the segment recorded a $1.4 million estimated warranty expense to repair a specific engine component in a series of U.S. Navy ships. The segment also recorded a $3 million estimated loss on an engine contract. The expected contract loss was a result of detrimental changes in the market for nuclear power plant emergency power engines after the tsunami in Japan, which caused costs per nuclear-related engine to be higher than expected, and the original engine costs for the program were underestimated. These large costs were partially offset by cost reimbursements related to the canceled South Texas Project of approximately $1.8 million, which reduced expenses in the third quarter of 2011; the favorable resolution of a legal matter, amounting to $0.5 million; and approximately $1.5 million of incremental profit related to the use of percentage-of-completion accounting beginning in the third quarter of 2011. Operating margins dropped from 21.4% in 2010 to 16.5% in 2011.

Restructuring and Other Costs

Restructuring expense was $5.0 million, $1.4 million and $0.9 million for 2012, 2011 and 2010, respectively. During 2012, we initiated a number of restructuring activities throughout our operations, the most significant of which were at our Garlock, GGB and CPI businesses. At both Garlock and CPI, we consolidated several of our North American manufacturing operations and service centers into other existing sites. At GGB, we reduced the size of our workforce, primarily in Europe, as activity slowed in their markets. In addition, GGB also shut down their fluid film bearing product line, which began as a new product development effort a few years ago. Ultimately, the product did not prove to be commercially viable, and we made the decision to shut down production. Workforce reductions announced as a result of our 2012 restructuring activities totaled 189 salaried administrative and hourly manufacturing positions, most of which had been terminated by December 31, 2012.

Liquidity and Capital Resources

Cash requirements for, but not limited to, working capital, capital expenditures, acquisitions, pension contributions, and debt repayments have been funded from cash balances on hand, revolver borrowings and cash generated from operations. We are proactively pursuing acquisition opportunities. It is possible our cash requirements for one or more of these acquisition opportunities could exceed our cash balance at the time of closing. Should we need additional capital, we have other resources available, which are discussed in this section under the heading of “Capital Resources.”

As of December 31, 2012, we held no cash and cash equivalents in the United States and approximately $54 million in cash and cash equivalents outside of the United States. If the funds held outside the United States were needed for our operations in the U.S., we have several methods to repatriate without significant tax effects, including repayment of intercompany loans or distributions of previously taxed income. Other distributions may require us to incur U.S. or foreign taxes to repatriate these funds. However, as discussed in Note 5 to our Consolidated Financial Statements, our intent is to permanently reinvest these funds outside the U.S. and our current plans do not demonstrate a need to repatriate cash to fund our U.S. operations.

Cash Flows

Operating activities provided $118.2 million, $81.4 million and $35.7 million in 2012, 2011 and 2010, respectively. The increase in operating cash flows in 2012 versus 2011 was primarily attributable to a significant increase in working capital in 2011 of $25.3 million as compared to a $1.1 million decrease in 2012. Working capital needs in 2012 remained relatively constant with the levels at the end of 2011. Lower cash taxes paid of approximately $15 million also contributed to higher cash provided by operating activities in 2012 as compared to 2011. The lower cash taxes paid included $3.4 million of tax refunds in 2012 from overpayments in 2010 and $6.8 million in tax overpayments in 2011 applied to 2012. The increase in operating cash flows in 2011 versus 2010 was primarily attributable to our increased earnings and the tax payment resulting from the gain on the sale of Quincy Compressor made in 2010, which did not recur in 2011, partially offset by higher contributions to the U.S. defined benefit plans in 2011. In 2012 and 2011, GST reported $30.4 million and $44.2 million of operating cash flows, respectively, which were not included in our results.

We used $125.6 million, net, and $260.7 million, net, in 2012 and 2011, respectively, and received $109.7 million, net, in 2010, for investing activities. In 2012, we used $85.3 million net of cash acquired to purchase Motorwheel. Please refer to “Acquisitions and Dispositions” in Part I, Item 1 – “Business” for additional discussion regarding this transaction. We also invested $40.9 million in capital expenditures across all of our businesses. In 2011, we used $228.2 million net of cash acquired to purchase six businesses. Please refer to “Acquisitions and Dispositions” in Part I, Item 1 – “Business” for additional discussion regarding these transactions. We also spent $34.3 million for capital expenditures across all of our businesses. The net cash inflow provided by investing activities in 2010 resulted from the proceeds of the divestiture of Quincy Compressor. This cash receipt was partially offset by capital expenditures and the cash retained by GST LLC and its subsidiaries in connection with their deconsolidation. The deconsolidation of GST LLC is discussed further in this Management’s Discussion and Analysis of Financial Condition and Results of Operations in the “Garlock Sealing Technologies LLC and Garrison Litigation Management Group, Ltd.” section.

Financing activities of continuing operations provided $29.5 million, net, in 2012 and included net borrowings on the senior secured revolving credit facility of $28.3 million. Financing activities of continuing operations consumed $9.4 million, net, in 2011 and included our first borrowings on the senior secured revolving credit facility of $3.8 million, net, and the payment of related party notes to GST LLC of $13.1 million. Financing activities of continuing operations in 2010 included repayment of $6.1

million of related-party debt, which previously was eliminated in consolidation prior to the deconsolidation of GST LLC.

Capital Resources

Senior Secured Revolving Credit Facility. Our primary U.S. operating subsidiaries, other than GST LLC, are parties to a senior secured revolving credit facility with a maximum availability of $175 million, $30 million of which may be used for letters of credit. Actual borrowing availability under the credit facility is determined by reference to a borrowing base of specified percentages of eligible accounts receivable, inventory, equipment and certain real property, and is reduced by usage of the facility, including outstanding letters of credit, and any reserves. Under certain conditions, we may request an increase to the facility maximum availability by up to $50 million to $225 million in total. Any increase is dependent on obtaining future lender commitments for those amounts, and no current lender has any obligation to provide such commitment. The credit facility matures on July 17, 2015, unless, prior to that date, our convertible debentures are paid in full, refinanced on certain terms, or defeased, in which case the facility will mature on March 30, 2016.

Borrowings under the credit facility are secured by specified assets of ours and our U.S. operating subsidiaries, other than GST LLC, and primarily include accounts receivable, inventory, equipment, certain real property, deposit accounts, intercompany loans, intellectual property and related contract rights, general intangibles related to any of the foregoing and proceeds related to the foregoing. Subsidiary capital stock is not included as collateral.

Outstanding borrowings under the credit facility bear interest at a rate equal to, at our option, either: (1) a base/prime rate plus an applicable margin, or (2) the adjusted one, two, three or six-month LIBOR rate plus an applicable margin. Pricing under the credit facility at any particular time is determined by reference to a pricing grid based on average daily availability under the facility for the immediately prior fiscal quarter. Under the pricing grid, the applicable margins range from 0.75% to 1.25% for base/prime rate loans and from 1.75% to 2.25% for LIBOR loans. At December 31, 2012, the applicable margin for base/prime rate loans was 1.00% and the applicable margin for LIBOR loans was 2.00%. The undrawn portion of the credit facility is subject to an unused line fee calculated at an annual rate of 0.375%. Outstanding letters of credit are subject to an annual fee equal to the applicable margin for LIBOR loans under the credit facility as in effect from time to time, plus a fronting fee on the aggregate undrawn amount of the letters of credit at an annual rate of 0.125%.

The credit agreement contains customary covenants and restrictions for an asset-based credit facility, including a fixed charge test if availability falls below certain thresholds, and negative covenants limiting certain: fundamental changes (such as merger transactions); loans; incurrence of debt other than specifically permitted debt; transactions with affiliates that are not on arms-length terms; incurrence of liens other than specifically permitted liens; repayment of subordinated debt (except for scheduled payments in accordance with applicable subordination documents); prepayments of other debt; dividends; asset dispositions other than as specifically permitted; and acquisitions and other investments other than as specifically permitted.

As long as the amount available for borrowing under the facility exceeds $20 million, the limitation on fixed asset dispositions is not applicable. The limitations on acquisitions, investments in foreign subsidiaries, dividends (including those required to make payments on our convertible debentures), incurrence of certain cash collateral liens and prepayment of debt other than subordinated debt are generally not applicable if certain financial conditions are satisfied related to the facility.

The credit facility contains events of default including, but not limited to, nonpayment of principal or interest, violation of covenants, breaches of representations and warranties, cross-default to

37

Table of Contents

other debt, bankruptcy and other insolvency events, material judgments, certain ERISA events, actual or asserted invalidity of loan documentation and certain changes of control of the Company.

The actual borrowing availability at December 31, 2012, under our senior secured revolving credit facility was $90.7 million after giving consideration to $3.8 million of letters of credit outstanding and $34.3 million of revolver borrowings. The maximum amount borrowed under this facility during 2012 was $112.0 million.

Convertible Debentures. We issued $172.5 million of convertible debentures in 2005. The debentures bear interest at an annual rate of 3.9375%, and we pay accrued interest on April 15 and October 15 of each year. The debentures will mature on October 15, 2015, unless they are converted prior to that date. The debentures are direct, unsecured and unsubordinated obligations and rank equal in priority with our unsecured and unsubordinated indebtedness and will be senior in right of payment to all subordinated indebtedness. They effectively rank junior to our secured indebtedness to the extent of the value of the assets securing such indebtedness. The debentures do not contain any financial covenants. Holders may convert the debentures into cash and shares of our common stock at an initial conversion rate of 29.5972 shares of common stock per $1,000 principal amount of debentures, which is equal to an initial conversion price of $33.79 per share, subject to adjustment, before the close of business on October 15, 2015. Upon conversion, we would deliver (i) cash equal to the lesser of the aggregate principal amount of the debentures to be converted or our total conversion obligation, and (ii) shares of our common stock in respect of the remainder, if any, of our conversion obligation. Conversion is permitted only under certain conditions, none of which were satisfied as of December 31, 2012.

For a discussion of the potential liquidity issues and risks we could face in the event some or all of the Debentures are converted, see Part I, Item 1A, “Risk Factors – We may not have sufficient cash to repurchase our convertible debentures at the option of the holder or upon a change of control or to pay the cash payable upon a conversion” in this report.

We used a portion of the net proceeds from the sale of the debentures to enter into call options, i.e., hedge and warrant transactions, which entitle us to purchase shares of our stock from a financial institution at $33.79 per share and entitle the financial institution to purchase shares of our stock from us at $46.78 per share. This will reduce potential dilution to our common stockholders from conversion of the Debentures and have the effect to us of increasing the conversion price of the debentures to $46.78 per share.

Related Party Notes. Effective as of January 1, 2010, Coltec entered into a $73.4 million Amended and Restated Promissory Note due January 1, 2017 (the “Coltec Note”) in favor of GST LLC, and our subsidiary Stemco LP entered into a $153.8 million Amended and Restated Promissory Note due January 1, 2017, in favor of GST LLC (the “Stemco Note”, and together with the Coltec Note, the “Intercompany Notes”). The Intercompany Notes amended and replaced promissory notes in the same principal amounts which were initially issued in March 2005, and which expired on January 1, 2010.

The Intercompany Notes bear interest at 11% per annum, of which 6.5% is payable in cash and 4.5% is added to the principal amount of the Intercompany Notes as payment-in-kind (“PIK”) interest. If GST LLC is unable to pay ordinary course operating expenses, under certain conditions, GST LLC can require Coltec and Stemco to pay in cash the accrued PIK interest necessary to meet such ordinary course operating expenses, subject to a cap of 1% of the principal balance of each Intercompany Note in any calendar month and 4.5% of the principal balance of each Intercompany Note in any year. The interest due under the Intercompany Notes may be satisfied through offsets of amounts due under intercompany services agreements pursuant to which the Company provides certain corporate services, makes available access to group insurance coverage to GST, makes advances to third party providers related to payroll and certain benefit plans sponsored by GST, and permits employees of GST to participate in certain of the

38

Table of Contents

Company’s benefit plans. In 2012 and 2011, PIK interest of $10.7 million and $10.2 million, respectively, was added to the principal balance of the Intercompany Notes, resulting in a total Notes Payable to GST balance of $248.1 million.

The Coltec Note is secured by Coltec’s pledge of certain of its equity ownership in specified U.S. subsidiaries. The Stemco Note is guaranteed by Coltec and secured by Coltec’s pledge of its interest in Stemco. The Notes are subordinated to any obligations under the Company’s senior secured revolving credit facility.

Garlock Sealing Technologies LLC and Garrison Litigation Management Group, Ltd.

The historical business operations of GST LLC and Anchor have resulted in a substantial volume of asbestos litigation in which plaintiffs have alleged personal injury or death as a result of exposure to asbestos fibers. Those subsidiaries manufactured and/or sold industrial sealing products, predominately gaskets and packing, containing encapsulated asbestos fibers. Anchor is an inactive and insolvent indirect subsidiary of Coltec. The Company’s subsidiaries’ exposure to asbestos litigation and their relationships with insurance carriers have been managed through another Coltec subsidiary, Garrison.

On the Petition Date, GST LLC, Anchor and Garrison filed voluntary petitions for reorganization under Chapter 11 of the United States Bankruptcy Code in Bankruptcy Court. The filings were the initial step in a claims resolution process, which is ongoing. The goal of the process is an efficient and permanent resolution of all current and future asbestos claims through court approval of a plan of reorganization, which is expected to establish a trust to which all asbestos claims will be channeled for resolution. GST intends to seek an agreement with asbestos claimants and other creditors on the terms of a plan for the establishment of such a trust and repayment of other creditors in full, or in the absence of such an agreement an order of the Bankruptcy Court confirming such a plan.

Prior to its deconsolidation effective on the Petition Date, GST LLC and its subsidiaries operated as part of the Garlock group of companies within EnPro’s Sealing Products segment. GST LLC designs, manufactures and sells sealing products, including metallic, non-metallic and composite material gaskets, rotary seals, compression packing, resilient metal seals, elastomeric seals, hydraulic components, and expansion joints. GST LLC and its subsidiaries operate five primary manufacturing facilities, including GST LLC’s operations in Palmyra, New York and Houston, Texas.

Garrison’s principal business historically has been to manage the defense of all asbestos-related litigation affecting the Company’s subsidiaries, principally GST LLC and Anchor, arising from their sale or use of products or materials containing asbestos, and to manage, bill and collect available insurance proceeds. When it commenced business in 1996, Garrison acquired certain assets of GST LLC and assumed certain liabilities stemming from asbestos-related claims against GST LLC. Garrison is not itself a defendant in asbestos-related litigation and has no direct liability for asbestos-related claims. Rather, it has assumed GST LLC’s liability for such claims and agreed to indemnify GST LLC from liability with respect to such claims. Anchor was a distributor of products containing asbestos and was acquired by GST LLC in 1987. Anchor has been inactive and insolvent since 1993.

The financial results of GST and subsidiaries have been excluded from our consolidated results since the Petition Date. The investment in GST is presented using the cost method during the reorganization period and is subject to periodic reviews for impairment. The cost method requires us to present our ownership interests in the net assets of GST at the Petition Date as an investment and to not recognize any income or loss from GST and subsidiaries in our results of operations during the reorganization period. When GST emerges from the jurisdiction of the Bankruptcy Court, the subsequent accounting will be determined based upon the applicable circumstances and facts at such time, including

39

the terms of any plan of reorganization. See Note 18 to our Consolidated Financial Statements for condensed financial information for GST and subsidiaries.

GST’s third party sales and operating income from the date of deconsolidation through December 31, 2010, were $104.9 million and $16.5 million, respectively.

GST is included in our consolidated U.S. federal income tax return and certain state combined income tax returns. As the parent of these consolidated tax groups, we are liable for, and pay, income taxes owed by the entire group. We have agreed with GST to allocate group taxes to GST based on the U.S. consolidated tax return regulations and current accounting guidance. This method generally allocates current and deferred taxes to GST as if it were a separate taxpayer. As a result, we carry an income tax receivable from GST related to this allocation. At December 31, 2012, this amount was approximately $33 million. This receivable is expected to be collected in the future, subject to GST’s reorganization and the terms thereof.

As a result of the deconsolidation of GST, we conducted an analysis to compare the fair market value of GST to its book value. Based on this analysis, we recognized a $54.1 million non-cash pre-tax gain on the deconsolidation of GST in the second quarter of 2010. The fair value of GST, net of taxes on the gain on deconsolidation, was recorded at $236.9 million. Our $236.9 million investment value is subject to periodic reviews for impairment. GST will be presented using the cost method during the reorganization period.

We have assessed GST LLC’s and Garrison’s liquidity position as a result of the bankruptcy filing and believe they can continue to fund their operating activities, and those of their subsidiaries, and meet their capital requirements for the foreseeable future. However, the ability of GST LLC and Garrison to continue as going concerns is dependent upon their ability to resolve their ultimate asbestos liability in the bankruptcy from their net assets, future cash flows, and available insurance proceeds, whether through the confirmation of a plan of reorganization or otherwise. As a result of the bankruptcy filing and related events, there can be no assurance the carrying values of the assets, including the carrying value of the business and the tax receivable, will be realized or that liabilities will be liquidated or settled for the amounts recorded. In addition, a plan of reorganization, or rejection thereof, could change the amounts reported in the GST LLC and Garrison financial statements and cause a material change in the carrying amount of our investment. For additional information about GST’s bankruptcy proceeding, see Note 18 to our Consolidated Financial Statements and the sections entitled “Contingencies – Subsidiary Bankruptcy,” and “-Asbestos” in this Management’s Discussion and Analysis of Financial Condition and Results of Operation.

Dividends

To date, we have not paid dividends and we do not intend to pay a dividend in the foreseeable future. If availability under our senior secured revolving credit facility falls below $20 million, we would be limited in our ability to pay dividends. As of December 31 and throughout 2012, we exceeded this minimum threshold. The indenture that governs the convertible debentures does not restrict us from paying dividends.

Critical Accounting Policies and Estimates

The preparation of our Consolidated Financial Statements, in accordance with accounting principles generally accepted in the United States, requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosures pertaining to contingent assets and liabilities. Note 1, “Overview, Significant Accounting Policies and Recently Issued Pronouncements,” to the Consolidated Financial Statements describes the significant accounting policies

40

Table of Contents

used to prepare the Consolidated Financial Statements. On an ongoing basis we evaluate our estimates, including, but not limited to, those related to bad debts, inventories, intangible assets, income taxes, warranty obligations, restructuring, pensions and other postretirement benefits, and contingencies and litigation. We base our estimates on historical experience and on various other assumptions we believe to be reasonable under the circumstances. Actual results may differ from our estimates.

We believe the following accounting policies and estimates are the most critical. Some of them involve significant judgments and uncertainties and could potentially result in materially different results under different assumptions and conditions.

Revenue Recognition

Revenue is recognized at the time title and risk of product ownership is transferred or when services are rendered with the exception of engine revenue recognition in the Engine Products and Services segment as described in the next three paragraphs. Shipping costs billed to customers are recognized as revenue and expensed in cost of goods sold.

During the third quarter of 2011, the Engine Products and Services segment began using percentage-of-completion (“POC”) accounting for new and nearly new engine contracts rather than the completed-contract method. We made this change because, as a result of enhancements to the financial management and reporting systems, the segment is able to reasonably estimate the revenue, costs, and progress towards completion of engine builds. If we are not able to meet those conditions for a particular engine contract, the segment will recognize revenues using the completed-contract method. Progress towards completion is measured by reference to costs incurred to date as a percentage of estimated total project costs.

Recognized revenues and profits are subject to revisions during the engine build period in the event the assumptions regarding the overall contract outcome are revised. The cumulative effect of a revision in estimates is recorded in the period such a revision becomes likely and estimable. Losses on contracts in progress are accounted for in the period a loss becomes likely and estimable. We recognized revenues and operating income of $67.3 million and $13.1 million, respectively, for the year ended December 31, 2012, and revenues and operating income of $9.6 million and $1.5 million, respectively, for the year ended December 31, 2011 on contracts accounted for under the POC method.

The Engine Products and Services segment will continue to use the completed-contract method for engines in production at June 30, 2011. There has been no change in the revenue recognition policy for Engine Products and Services’ parts and services revenue or for the Sealing Products or Engineered Products segment.

Asbestos

Through the Petition Date, GST accrued a liability for known and estimated future expenditures to resolve asbestos claims for subsequent ten year periods and recorded legal fees and expenses only when incurred.

The significant assumptions underlying the material components of the estimated liability included: the number and trend of claims asserted; the mix of alleged diseases or impairment; the trend in the number of claims for malignant cases, primarily mesothelioma; the probability some existing and potential future claims would eventually be dismissed without payment; the estimated amount to be paid per claim; and the timing and impact of large amounts available for the payment of claims from the 524(g) trusts of former defendants in bankruptcy.

41

Table of Contents

With the assistance of Bates White, a recognized expert, we periodically reviewed the period over which we could make a reasonable estimate, the assumptions underlying the estimate, the range of reasonably possible potential liabilities and management’s estimate of the liability, and adjusted the estimate if necessary. Additional discussion is included in this Management’s Discussion and Analysis of Financial Condition and Results of Operations in “Contingencies – Asbestos.”

Derivative Instruments and Hedging Activities

We have entered into contracts to hedge forecasted transactions denominated in foreign currencies occurring at various dates through December 2014. We account for these contracts as derivatives. All derivatives are recognized on the balance sheet at their estimated fair value. On the date a derivative contract is entered into, we designate the derivative as a hedge of a recognized asset or liability (fair value hedge) or a hedge of a forecasted transaction or of the variability of cash flows to be received or paid related to a recognized asset or liability (cash flow hedge). We do not enter into derivatives for speculative purposes. Changes in the value of a fair value hedge are recorded in earnings along with the gain or loss on the hedged asset or liability, while changes in the value of cash flow hedges are recorded in accumulated other comprehensive loss, until earnings are affected by the variability of cash flows.

Pensions and Postretirement Benefits

We and certain of our subsidiaries sponsor domestic and foreign defined benefit pension and other postretirement plans. Major assumptions used in the accounting for these employee benefit plans include the discount rate, expected return on plan assets, rate of increase in employee compensation levels and assumed health care cost trend rates. Assumptions are determined based on data available to us and appropriate market indicators, and are evaluated each year as of the plans’ measurement date. A change in any of these assumptions could have a material effect on net periodic pension and postretirement benefit costs reported in the Consolidated Statements of Operations, as well as amounts recognized in the Consolidated Balance Sheets. See Note 14 to the Consolidated Financial Statements for a discussion of pension and postretirement benefits.

Income Taxes

We use the asset and liability method of accounting for income taxes. Temporary differences arising between the tax basis of an asset or liability and its carrying amount on the Consolidated Balance Sheet are used to calculate future income tax assets or liabilities. This method also requires the recognition of deferred tax benefits, such as net operating loss carryforwards. A valuation allowance is recorded to reduce deferred tax assets when it is more likely than not that a tax benefit will not be realized. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to the taxable income (losses) in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A tax benefit from an uncertain tax position is recognized only if we believe it is more likely than not that the position will be sustained on its technical merits. If the recognition threshold for the tax position is met, only the portion of the tax benefit that we believe is greater than 50 percent likely to be realized is recorded. See Note 5 to the Consolidated Financial Statements for a discussion of income taxes.

Goodwill and Other Intangible Assets

We do not amortize goodwill, but instead it is subject to annual impairment testing. The goodwill asset impairment test involves comparing the fair value of a reporting unit to its carrying amount. If the carrying amount of a reporting unit exceeds its fair value, a second step of comparing the implied fair

42

Table of Contents

value of the reporting unit’s goodwill to the carrying amount of that goodwill is required to measure the potential goodwill impairment loss. There are inherent assumptions and estimates used in developing future cash flows which require management to apply judgment to the analysis of intangible asset impairment, including projecting revenues, interest rates, cost of capital, royalty rates and tax rates. Many of the factors used in assessing fair value are outside the control of management, and it is reasonably likely that assumptions and estimates will change in future periods. These changes can result in future impairments. For additional information, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Overview and Outlook” as well as Notes 1 and 9 to the Consolidated Financial Statements.

Contingencies

General

A detailed description of certain environmental, asbestos and other legal matters relating to certain of our subsidiaries is included in this section. In addition to the matters noted herein, we are from time to time subject to, and are presently involved in, other litigation and legal proceedings arising in the ordinary course of business. We believe the outcome of such other litigation and legal proceedings will not have a material adverse effect on our financial condition, results of operations and cash flows. Expense for administrative and legal proceedings are recorded when incurred.

Environmental

Our facilities and operations are subject to federal, state and local environmental and occupational health and safety requirements of the U.S. and foreign countries. We take a proactive approach in our efforts to comply with environmental, health and safety laws as they relate to our operations and in proposing and implementing any remedial plans that may be necessary. We also regularly conduct comprehensive environmental, health and safety audits at our facilities to maintain compliance and improve operational efficiency.

Although we believe past operations were in substantial compliance with the then applicable regulations, we or one of our subsidiaries is involved at 17 sites where the cost per site for us or our subsidiary is expected to exceed $100 thousand. Investigations have been completed for 13 sites and are in progress at the other four sites. Our costs at a majority of these sites relate to remediation projects for soil and groundwater contamination at former operating facilities that were sold or closed.

As of December 31, 2012 and 2011, EnPro had accrued liabilities of $11.3 million and $12.6 million, respectively, for estimated future expenditures relating to environmental contingencies. Given the uncertainties regarding the status of laws, regulations, enforcement policies, the impact of other parties potentially being liable, technology and information related to individual sites, we do not believe it is possible to develop an estimate of the range of reasonably possible environmental loss in excess of our recorded liabilities. In addition, based on our prior ownership of Crucible Steel Corporation a/k/a Crucible, Inc. (“Crucible”), we may have additional contingent liabilities in one or more significant environmental matters, which are included in the 17 sites referred to above. Except with respect to specific Crucible environmental matters for which we have accrued a portion of the liability set forth above, we are unable to estimate a reasonably possible range of loss related to these contingent liabilities. See Note 19 to the Consolidated Financial Statements for additional information regarding our environmental contingencies and see the section titled “Crucible Steel Corporation a/k/a Crucible, Inc.” in this Management’s Discussion and Analysis of Financial Condition and Results of Operation.

Colt Firearms and Central Moloney

We may have contingent liabilities related to divested businesses for which certain of our subsidiaries retained liability or are obligated under indemnity agreements. These contingent liabilities include, but are not limited to, potential product liability and associated claims related to firearms manufactured prior to March 1990 by Colt Firearms, a former operation of Coltec, and for electrical transformers manufactured prior to May 1994 by Central Moloney, another former Coltec operation. We believe that these potential contingent liabilities are not material to the Company’s financial condition, results of operation and cash flows. Coltec also has ongoing obligations, which are included in other liabilities in our Consolidated Balance Sheets, with regard to workers’ compensation, retiree medical and other retiree benefit matters that relate to Coltec’s periods of ownership of these operations.

Crucible Steel Corporation a/k/a Crucible, Inc.

Crucible Steel Corporation a/k/a Crucible, Inc. (“Crucible”), which was engaged primarily in the manufacture and distribution of high technology specialty metal products, was a wholly owned subsidiary of Coltec until 1983 when its assets and liabilities were distributed to a new Coltec subsidiary, Crucible Materials Corporation. Coltec sold a majority of the outstanding shares of Crucible Materials Corporation in 1985 and divested its remaining minority interest in 2004. Crucible Materials Corporation filed for Chapter 11 bankruptcy protection in May 2009 and is no longer conducting operations. We have certain ongoing obligations, which are included in other liabilities in our Consolidated Balance Sheets, including workers’ compensation, retiree medical and other retiree benefit matters, related to Coltec’s period of ownership of Crucible. Based on Coltec’s prior ownership of Crucible, we may have certain other contingent liabilities, including liabilities in one or more significant environmental matters included in the matters discussed in “Environmental,” above. We are investigating these matters. Except with respect to those matters for which we have an accrued liability as discussed in “Environmental” above, we are unable to estimate a reasonably possible range of loss related to these contingent liabilities. See Note 19 to the Consolidated Financial Statements for information about certain liabilities relating to Coltec’s ownership of Crucible.

Subsidiary Bankruptcy

Three of our subsidiaries filed voluntary Chapter 11 bankruptcy petitions on the Petition Date as a result of tens of thousands of pending and estimated future asbestos personal injury claims. The filings were the initial step in a claims resolution process. The goal of the process is an efficient and permanent resolution of all pending and future asbestos claims through court approval of a plan of reorganization that will establish a trust to which all asbestos claims will be channeled for resolution and payment.

In November 2011, GST filed a proposed plan of reorganization with the Bankruptcy Court. The proposed plan calls for a trust to be formed, to which GST and affiliates would contribute $200 million and which would be the exclusive remedy for future asbestos personal injury claimants – those whose claims arise after confirmation of the plan. The proposed plan provides that each present personal injury claim (any pending claim or one that arises between the Petition Date and plan confirmation) will be assumed by reorganized GST and resolved either by settlement pursuant to a matrix contained in the proposed plan or as otherwise agreed, or by payment in full of any judgment entered after trial in federal court. Based on a preliminary estimate provided by Bates White, the estimation expert retained by counsel to GST, prior to the time that GST filed its proposed plan, GST estimates that the indemnity costs to resolve all present claims pursuant to the settlement matrix in the plan would cost reorganized GST approximately $70 million. Under the proposed plan, all non-asbestos claimants would be paid the full value of their claims.

GST’s proposed plan is opposed by the Official Committee of Asbestos Personal Injury Claimants (the “Claimants’ Committee”) and the Future Claimants’ Representative (the “FCR” and together with the Claimants’ Committee, “claimant representatives”) and is unlikely to be approved in its

current form. The claimant representatives have announced their intention to file a competing proposed plan of reorganization.

Update. On April 13, 2012, the Bankruptcy Court granted a motion by GST for the Bankruptcy Court to estimate the allowed amount of present and future asbestos claims against GST for mesothelioma, a rare cancer attributed to asbestos exposure, for purposes of determining the feasibility of a proposed plan of reorganization. The court has tentatively scheduled the estimation trial to begin in July 2013.

GST and the Claimants’ Committee and FCR have proposed different approaches to estimating allowed asbestos personal injury claims against GST, and the Bankruptcy Court ruled that each could present its proposed approach. GST will offer a merits-based approach that focuses on its legal defenses to liability and takes account of claimants’ recoveries from other sources, including trusts established in Chapter 11 cases filed by GST’s co-defendants, in estimating potential future recoveries by claimants from GST. We anticipate that the Claimants’ Committee and FCR will offer a settlement-based theory of estimation.

During the course of the Chapter 11 proceedings, the claimant representatives have asserted that affiliates of the filed entities, including the Company and Coltec, should be held responsible for the asbestos liabilities of the filed entities under various theories of derivative corporate responsibility including veil-piercing and alter ego. Claimant representatives filed a motion with the Bankruptcy Court asking for permission to sue us based on those theories. In a decision dated June 7, 2012, the Bankruptcy Court denied the claimant representatives’ motion without prejudice, thereby potentially allowing the representatives to re-file the motion after the estimation trial scheduled for 2013. We believe there will be no reason for the claimant representatives to re-file the motion because the derivative claims will likely be moot after the estimation trial, as we believe that the estimation trial will result in an estimate of aggregate liability for asbestos claims that GST is capable of fully funding.

From time to time during the case we have engaged in settlement discussions with asbestos claimant representatives and we anticipate that we will continue to do so; however, there can be no assurance that a settlement will be reached and, if so, when that might occur.

From the Petition Date through December 31, 2012, GST has recorded Chapter 11 case-related fees and expenses totaling $57.4 million. The total includes $31.3 million for fees and expenses of GST’s counsel and experts; $21.3 million for fees and expenses of counsel and experts for the asbestos claimants’ committee, and $4.8 million for the fees and expenses of the future claims representative and his counsel and experts. GST recorded $31.4 million of those case-related fees and expenses in 2012 compared to $17.0 million in 2011, and $9.0 million in 2010. GST attributes the large year-over-year increase to increased activity in the case, including activity related to discovery disputes, the identification and preparation of experts for estimation, and claimant representatives’ efforts to extend GST’s liability to affiliates.

Asbestos

Background on Asbestos-Related Litigation. The historical business operations of GST LLC and Anchor resulted in a substantial volume of asbestos litigation in which plaintiffs alleged that exposure to asbestos fibers in products produced or sold by GST LLC or Anchor, together with products produced and sold by numerous other companies, contributed to the bodily injuries or deaths. GST LLC and

45

Table of Contents

Anchor manufactured and/or sold industrial sealing products that contained encapsulated asbestos fibers. Other of our subsidiaries that manufactured or sold equipment that may have at various times in the past contained asbestos-containing components have also been named in a number of asbestos lawsuits, but only GST LLC and Anchor have ever paid an asbestos claim.

Since the first asbestos-related lawsuits were filed against GST LLC in 1975, GST LLC and Anchor have processed more than 900,000 claims to conclusion, and, together with insurers, have paid over $1.4 billion in settlements and judgments and over $400 million in fees and expenses. Our subsidiaries’ exposure to asbestos litigation and their relationships with insurance carriers have been managed through Garrison.

Beginning in 2000, the top-tier asbestos defendants—companies that paid most of the plaintiffs’ damages because they produced and sold huge quantities of highly friable asbestos products—sought bankruptcy protection and stopped paying asbestos claims in the tort system. The bankruptcies of many additional producers of friable asbestos products followed. The plaintiffs could no longer pursue actions against these large defendants during the pendency of their bankruptcy proceedings, even though these defendants had historically been determined to be the largest contributors to asbestos-related injuries. Many plaintiffs pursued GST LLC in civil court actions to recover compensation formerly paid by top-tier bankrupt companies under state law principles of joint and several liability and began identifying GST LLC’s non-friable sealing products as a primary cause of their asbestos diseases, while generally denying knowledge of exposure to the friable products of companies in bankruptcy. GST LLC believes this targeting strategy effectively shifted damages caused by top tier defendants that produced friable asbestos products to GST LLC, thereby materially increasing GST LLC’s cost of defending and resolving claims.

Almost all of the top-tier defendants that sought bankruptcy relief in the early 2000s have now emerged, or are positioning to emerge, from bankruptcy. Their asbestos liabilities have been assumed by wealthy 524(g) trusts created in the bankruptcies with assets contributed by the emerging former defendants and their affiliates. With the emergence of these companies from bankruptcy, many plaintiffs seek compensation from the 524(g) trusts. These trusts have aggregate assets exceeding $30 billion ($36.8 billion at September 23, 2011, according to a study released in September 2011 by the United States Government Accountability Office) specifically set aside to compensate individuals with asbestos diseases caused by the friable products of those defendants. We believe that as billions of dollars of 524(g) trust assets continue to become available to claimants, defendants will obtain significant reductions in their costs to defend and resolve claims. As of the Petition Date, however, the establishment of these 524(g) trusts had taken longer than anticipated and the trusts had a significant backlog of claims that accumulated while the trusts were being established. Additionally, procedures adopted for the submissions of asbestos claims in bankruptcy cases and against 524(g) trusts make it difficult for GST LLC and other tort-system co-defendants to gain access to information about claims made against bankrupt defendants or the accompanying evidence of exposure to the asbestos-containing products of such bankrupt defendants. We believe that these procedures enable claimants to “double dip” by collecting payments from remaining defendants in the tort system under joint-and-several-liability principles for injuries caused by the former top-tier defendants while also collecting substantial additional amounts from 524(g) trusts established by those former defendants to pay asbestos claims. Because of these factors, while several 524(g) trusts had begun making substantial payments to claimants prior to the Petition Date, GST LLC had not yet experienced a significant reduction in damages being sought from GST LLC.

Subsidiary Chapter 11 Filing and Its Effect. In light of GST LLC’s experience that (a) its cost of defending and resolving claims had not yet declined as anticipated although 524(g) trusts had begun making substantial payments to claimants, and (b) new mesothelioma claims filings against it in recent years had not declined at a rate similar to the rate of decline in disease incidence, GST initiated voluntary

46

Table of Contents

proceedings under Chapter 11 of the United States Bankruptcy Code as a means to determine and comprehensively resolve their asbestos liability. The filings were the initial step in an ongoing claims resolution process.

During the pendency of the Chapter 11 proceedings, certain actions proposed to be taken by GST not in the ordinary course of business will be subject to approval by the Bankruptcy Court. As a result, during the pendency of these proceedings, we will not have exclusive control over these companies. Accordingly, as required by GAAP, GST was deconsolidated beginning on the Petition Date.

As a result of the initiation of the Chapter 11 proceedings, the resolution of asbestos claims is subject to the jurisdiction of the Bankruptcy Court. The filing of the Chapter 11 cases automatically stayed the prosecution of pending asbestos bodily injury and wrongful death lawsuits, and initiation of new such lawsuits, against GST. Further, the Bankruptcy Court issued an order enjoining plaintiffs from bringing or further prosecuting asbestos products liability actions against affiliates of GST, including EnPro, Coltec and all their subsidiaries, during the pendency of the Chapter 11 proceedings, subject to further order. As a result, the numbers of new claims filed against our subsidiaries and, except as a result of the resolution of appeals from verdicts rendered prior to the Petition Date and information about pending cases obtained in the Chapter 11 proceedings, the numbers of claims pending against them have not changed since the Petition Date, and those numbers continue to be as reported in our 2009 Form 10-K and our quarterly reports for the first and second quarters of 2010. See the section entitled “Subsidiary Bankruptcy” in this Management’s Discussion and Analysis of Financial Condition and Results of Operations for additional information and an update on the GST asbestos claims resolution process.

Pending Claims. On the Petition Date, according to Garrison, there were more than 90,000 total claims pending against GST LLC, and approximately 5,800 claims alleging the disease mesothelioma. Mesothelioma is a rare cancer of the protective lining of many of the body’s internal organs, principally the lungs. The primary cause of mesothelioma is believed to be exposure to asbestos. As a result of asbestos tort reform during the 2000s, most active asbestos-related lawsuits, and a large majority of the amount of payments made by our subsidiaries, have been as a result of claims alleging mesothelioma. In total, GST LLC has paid $563.2 million to resolve a total of 15,300 mesothelioma claims, and another 5,700 mesothelioma claims have been dismissed without payment.

In order to estimate the allowed amount for mesothelioma claims against GST, the Bankruptcy Court approved a process whereby all current GST LLC mesothelioma claimants were required to respond to a questionnaire about their claims. Questionnaires were distributed to the mesothelioma claimants identified in Garrison’s claims database. Many of the 5,800 claimants (over 600) did not respond to the questionnaire at all, many others (more than 1,700) acknowledged that they do not have mesothelioma, that they cannot establish exposure to GST products, or that their claims were dismissed, settled or withdrawn. Still others responded to the questionnaire but their responses are deficient in some material respect. As a result of this process, less than 3,500 claimants have presented questionnaires asserting mesothelioma claims against GST LLC as of the Petition Date and many of them have not established exposure to GST products or have claims that are otherwise deficient.

Since the Petition Date, many asbestos-related lawsuits have been filed by claimants against other companies in state and federal courts, and many of those claimants might also have included GST LLC as a defendant but for the bankruptcy injunction. Many of those claimants likely will make claims against GST in the bankruptcy proceeding.

Product Defenses. We believe that the asbestos-containing products manufactured or sold by GST could not have been a substantial contributing cause of any asbestos-related disease. The asbestos in the products was encapsulated, which means the asbestos fibers incorporated into the products during the

47

Table of Contents

manufacturing process were sealed in binders. The products were also nonfriable, which means they could not be crumbled by hand pressure. The U.S. Occupational Safety and Health Administration, which began generally requiring warnings on asbestos-containing products in 1972, has never required that a warning be placed on products such as GST LLC’s gaskets. Even though no warning label was required, GST LLC included one on all of its asbestos-containing products beginning in 1978. Further, gaskets such as those previously manufactured and sold by GST LLC are one of the few asbestos-containing products still permitted to be manufactured under regulations of the U.S. Environmental Protection Agency. Nevertheless, GST LLC discontinued all manufacture and distribution of asbestos-containing products in the U.S. during 2000 and worldwide in mid-2001.

Appeals. GST LLC has a record of success in trials of asbestos cases, especially before the bankruptcies of many of the historically significant asbestos defendants that manufactured raw asbestos, asbestos insulation, refractory products or other dangerous friable asbestos products. However, it has on occasion lost jury verdicts at trial. GST has consistently appealed when it has received an adverse verdict and has had success in a majority of those appeals. We believe that GST LLC will continue to be successful in the appellate process, although there can be no assurance of success in any particular appeal. At December 31, 2012, three GST LLC appeals are pending from adverse decisions totaling $2.4 million.

GST LLC won reversals of adverse verdicts in one of two recent appellate decisions. In September 2011, the United States Court of Appeals for the Sixth Circuit overturned a $500 thousand verdict against GST LLC that was handed down in 2009 by a Kentucky federal court jury. The federal appellate court found that GST LLC’s motion for judgment as a matter of law should have been granted because the evidence was not sufficient to support a determination of liability. The Sixth Circuit’s chief judge wrote that, “On the basis of this record, saying that exposure to Garlock gaskets was a substantial cause of [claimant’s] mesothelioma would be akin to saying that one who pours a bucket of water into the ocean has substantially contributed to the ocean’s volume.” In May 2011, a three-judge panel of the Kentucky Court of Appeals upheld GST LLC’s $700 thousand share of a jury verdict, which included punitive damages, in a lung cancer case against GST LLC in Kentucky state court. This verdict, which was secured by a bond pending the appeal, was paid in June 2012.

Insurance Coverage. At December 31, 2012, we had $141.9 million of insurance coverage we believe is available to cover current and future asbestos claims payments and certain expense payments. GST has collected insurance payments totaling $53.2 million since the Petition Date. Of the $141.9 million of available insurance coverage remaining, we consider $140.0 million (99%) to be of high quality because the insurance policies are written or guaranteed by U.S.-based carriers whose credit rating by S&P is investment grade (BBB-) or better, and whose AM Best rating is excellent (A-) or better. We consider $1.9 million (1%) to be of moderate quality because the insurance policies are written with various London market carriers. Of the $141.9 million, $105.9 million is allocated to claims that were paid by GST LLC prior to the initiation of the Chapter 11 proceedings and submitted to insurance companies for reimbursement, and the remainder is allocated to pending and estimated future claims. There are specific agreements in place with carriers covering $106.2 million of the remaining available coverage. Based on those agreements and the terms of the policies in place and prior decisions concerning coverage, we believe that substantially all of the $141.9 million of insurance proceeds will ultimately be collected, although there can be no assurance that the insurance companies will make the payments as and when due. The $141.9 million is in addition to the $16.1 million collected in 2012. Based on those agreements and policies, some of which define specific annual amounts to be paid and others of which limit the amount that can be recovered in any one year, we anticipate that $36.7 million will become collectible at the conclusion of GST’s Chapter 11 proceeding and, assuming the insurers pay according to the agreements and policies, that the following amounts should be collected in the years set out below regardless of when the case concludes:

48

Table of Contents

2013 – $21.2 million

2014 – $22 million

2015 – $20 million

2016 – $18 million

2017 – $13 million

2018 – $11 million

In addition, GST LLC has received $7.2 million of insurance recoveries from insolvent carriers since 2007 (including $4.4 million in 2012) and may receive additional payments from insolvent carriers in the future. No anticipated insolvent carrier collections are included in the $141.9 million of anticipated collections. The insurance available to cover current and future asbestos claims is from comprehensive general liability policies that cover Coltec and certain of its other subsidiaries in addition to GST LLC for periods prior to 1985 and therefore could be subject to potential competing claims of other covered subsidiaries and their assignees.

Liability Estimate. Our recorded asbestos liability as of the Petition Date was $472.1 million. We based that recorded liability on an estimate of probable and estimable expenditures to resolve asbestos personal injury claims under generally accepted accounting principles, made with the assistance of Garrison and an estimation expert, Bates White, retained by GST LLC’s counsel. The estimate developed was an estimate of the most likely point in a broad range of potential amounts that GST LLC might pay to resolve asbestos claims (by settlement in the majority of the cases except those dismissed or tried) over the ten-year period following the Petition Date in the state court system, plus accrued but unpaid legal fees. The estimate, which was not discounted to present value, did not reflect GST LLC’s views of its actual legal liability; GST LLC has continuously maintained that its products could not have been a substantial contributing cause of any asbestos disease. Instead, the liability estimate reflected GST LLC’s recognition that most claims would be resolved more efficiently and at a significantly lower total cost through settlements without any actual liability determination.

Neither we nor GST has endeavored to update the accrual since the Petition Date except as necessary to reflect payments of accrued fees and the disposition of cases on appeal. After those necessary updates, the liability accrual at December 31, 2012 was $466.8 million. In each asbestos-driven Chapter 11 case that has been resolved previously, the amount of the debtor’s liability has been determined as part of a consensual plan of reorganization agreed to by the debtor and its creditors, including asbestos claimants and a representative of potential future claimants. GST does not believe that there is a reliable process by which an estimate of such a resolution can be made and therefore believes that there is no basis upon which it can revise the estimate last updated prior to the Petition Date. In addition, we do not believe that we can make a reasonable estimate of a specific range of more likely outcomes with respect to the asbestos liability of GST, and therefore, while we believe it to be an unlikely worst case scenario, GST’s ultimate costs to resolve all asbestos claims against it could range up to the total value of GST.

In a proposed plan of reorganization filed by GST and opposed by claimant representatives, GST has proposed to resolve all pending and future claims. GST has estimated that the amounts to be paid into the trust created by the plan for payments to future claimants, plus the indemnity costs incurred under the plan to pay present claimants, would be approximately $270 million. See the section entitled “Subsidiary Bankruptcy” in this Management’s Discussion and Analysis of Financial condition and Results of Operations. Claimant representatives, on the other hand, have asserted that GST’s liability exceeds the value of GST.

The proposed plan of reorganization includes provisions that would resolve any and all alleged derivative claims against us based on GST asbestos products. The provisions specify that we would fund $30 million of the amount proposed to be paid into the trust to pay future claimants and would guarantee

49

Table of Contents

the obligations of GST under the plan. Those provisions are incorporated into the terms of the proposed plan only in the context of the specifics of that plan, which would result in the equity interests of GST being retained by GST’s equity holder, the reconsolidation of GST into the Company with substantial equity above the amount of equity currently included in our consolidated financial statements, and an injunction protecting us from future GST claims.

We cannot predict when a plan of reorganization for GST might be approved and effective; however an estimation trial for the purpose of determining the number and value of allowed mesothelioma claims for plan feasibility purposes has been tentatively scheduled for July 2013. We believe that GST will present compelling defenses at the estimation trial that, among other things, GST’s products could not have been a substantial contributing cause of any asbestos-related disease. Therefore, GST believes the amounts that will be paid under its proposed plan would be far more than sufficient to fully fund its actual legal liability. There are many potential hurdles to plan confirmation, including appeals, that could arise during and after the estimation trial.

Quantitative Claims and Insurance Information. Our recorded asbestos liability at the Petition Date was $472.1 million. As of the Petition Date, we had remaining insurance and trust coverage of $192.4 million, which included $156.3 million in insured claims and expenses our subsidiaries have paid out in excess of amounts recovered from insurance. These amounts are recoverable under the terms of our insurance policies, subject to potential competing claims of other covered subsidiaries, and have been billed to the insurance carriers.

Off Balance Sheet Arrangements

Lease Agreements

We have a number of operating leases primarily for real estate, equipment and vehicles. Operating lease arrangements are generally utilized to secure the use of assets from time to time if the terms and conditions of the lease or the nature of the asset makes the lease arrangement more favorable than a purchase. As of December 31, 2012, approximately $56.3 million of future minimum lease payments were outstanding under these agreements. See Note 19, “Commitments and Contingencies – Other Commitments,” to the Consolidated Financial Statements for additional disclosure.

Contractual Obligations

A summary of our contractual obligations and commitments at December 31, 2012, is as follows:

Payment for long-term debt may be accelerated under certain circumstances because the convertible debentures due in 2015 may be converted earlier, requiring payment of the principal amount

50

Table of Contents

thereof in cash. In the event of an early conversion, we believe we would refinance the convertible debentures with an unsecured public debt offering or with other funding available at the time. The payments for long-term debt shown in the table above reflect the contractual principal amount for the convertible debentures. In our Consolidated Balance Sheet, this amount is shown net of a debt discount pursuant to the applicable accounting rules. Additional discussion regarding the convertible debentures is included in this Management’s Discussion and Analysis of Financial Condition and Results of Operations in “Liquidity and Capital Resources – Capital Resources,” and in Note 12 to the Consolidated Financial Statements. The interest on long-term debt represents the contractual interest coupon. It does not include the debt discount accretion, which also is a component of interest expense.

The notes payable to GST LLC bear interest at 11% per annum, of which 6.5% is payable in cash and 4.5% is added to the principal amount as payment-in-kind (“PIK”) interest. If GST LLC is unable to pay ordinary course operating expenses, under certain conditions, GST LLC can require the Company to pay in cash the accrued PIK interest necessary to meet such ordinary course operating expenses, subject to a cap of 1% of the principal balance of each note in any calendar month and 4.5% of the principal balance of each note in any year. The interest due under the notes payable to GST LLC may be satisfied through offsets of amounts due under intercompany services agreements pursuant to which the Company provides certain corporate services and insurance coverages to GST LLC, makes advances to third party providers related to payroll and certain benefit plans sponsored by GST LLC, and permits employees of GST LLC to participate in certain of the Company’s benefit plans. The table above reflects $82.0 million of total PIK interest as principal payments at the due date of the notes.

Payments for other long-term liabilities are estimates of amounts to be paid for environmental and retained liabilities of previously owned businesses included in the Consolidated Balance Sheets at December 31, 2012. These estimated payments are based on information currently known to us. However, it is possible that these estimates will vary from actual results and it is possible that these estimates may be updated in the future if new information becomes available in the future or if there are changes in the facts and circumstances related to these liabilities. Additional discussion regarding these liabilities is included earlier in this Management’s Discussion and Analysis of Financial Condition and Results of Operations in “Contingencies – Environmental, Contingencies – Colt Firearms and Central Moloney,” “Contingencies – Crucible Steel Corporation a/k/a Crucible, Inc.,” and in Note 19 to the Consolidated Financial Statements.

The table does not include obligations under our pension and postretirement benefit plans, which are included in Note 14 to the Consolidated Financial Statements.

We are exposed to certain market risks as part of our ongoing business operations, including risks from changes in foreign currency exchange rates and interest rates that could affect our financial condition, results of operations and cash flows. We manage our exposure to these and other market risks through normal operating and financing activities and through the use of derivative financial instruments. We intend to use derivative financial instruments as risk management tools and not for speculative investment purposes.

Interest Rate Risk

We are exposed to interest rate risk as a result of our outstanding debt obligations. The table below provides information about our fixed rate debt obligations as of December 31, 2012. The table represents principal cash flows (in millions) and related weighted average interest rates by expected (contractual) maturity dates.

51

Table of Contents

Additionally, we had $34.2 million outstanding on our revolving credit facility as of December 31, 2012, which has a variable interest rate. A change in interest rates on variable-rate debt affects the interest incurred and cash flows, but does not affect the net financial instrument position.

Foreign Currency Risk

We are exposed to foreign currency risks arising from normal business operations. These risks include the translation of local currency balances of our foreign subsidiaries, intercompany loans with foreign subsidiaries and transactions denominated in foreign currencies. Our objective is to control our exposure to these risks and limit the volatility in our reported earnings due to foreign currency fluctuations through our normal operating activities and, where appropriate, through foreign currency forward contracts and option contracts. The following table provides information about our outstanding foreign currency forward and option contracts as of December 31, 2012.

Commodity Risk

We source a wide variety of materials and components from a network of global suppliers. While such materials are typically available from numerous suppliers, commodity raw materials such as steel, engineered plastics, copper and polymers, are subject to price fluctuations, which could have a negative impact on our results. We strive to pass along such commodity price increases to customers to avoid profit margin erosion and utilize lean initiatives to further mitigate the impact of commodity raw material price fluctuations as we achieve improved efficiencies. We do not hedge commodity risk with any market risk sensitive instruments.

Disclosure Controls and Procedures

As of the end of the period covered by this report, we carried out an evaluation, under the supervision and with the participation of our chief executive officer and chief financial officer, of the effectiveness of the design and operation of our disclosure controls and procedures. The purpose of our disclosure controls and procedures is to provide reasonable assurance that information required to be disclosed in our reports filed under the Exchange Act, including this report, is recorded, processed, summarized and reported within the time periods specified, and that such information is accumulated and communicated to our management to allow timely decisions regarding disclosure.

Management does not expect our disclosure controls and procedures or internal controls to prevent all errors and all fraud. A control system, no matter how well conceived or operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance all control issues and instances of fraud, if any, within the company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty and that breakdowns can occur because of simple error or mistake. Controls can also be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the controls. The design of any system of controls is based in part on certain assumptions about the likelihood of future events, and there can be no assurance any design will succeed in achieving its stated goals under all potential future conditions. Over time, controls may become inadequate because of changes in conditions or deterioration in the degree of

53

Table of Contents

compliance with polices or procedures. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

Based on the controls evaluation, our chief executive officer and chief financial officer have concluded that our disclosure controls and procedures are effective to reasonably ensure that information required to be disclosed in our reports filed under the Exchange Act is recorded, processed, summarized and reported within the time periods specified, and that management will be timely alerted to material information required to be included in our periodic reports filed with the Securities and Exchange Commission.

In addition, no change in our internal control over financial reporting has occurred during the quarter ended December 31, 2012, which has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Management’s Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Rule 13a-15(f) under the Exchange Act. Our internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with policies and procedures may deteriorate. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation.

We carried out an evaluation, under the supervision and with the participation of our chief executive officer and our chief financial officer, of the effectiveness of our internal control over financial reporting as of the end of the period covered by this report. However, the assessment did not include the following operations we acquired within the past year, none of which, individually or in the aggregate, would be considered significant under Rule 1-02(w) of Regulation S-X of the SEC: Motorwheel Commercial Vehicle Systems, Inc. In making this assessment, we used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control-Integrated Framework. Based on our assessment, we have concluded, as of December 31, 2012, our internal control over financial reporting was effective based on those criteria.

The effectiveness of our internal control over financial reporting as of December 31, 2012, has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report which appears in this Annual Report on Form 10-K.
