ENPRO INDUSTRIES, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

1. Overview, Basis of Presentation and Recently Issued Authoritative Accounting Guidance

Overview

EnPro Industries, Inc. (“we,” “us,” “our,” “EnPro” or the “Company”) is a leader in the design, development, manufacture and marketing of proprietary engineered industrial products that primarily include: sealing products; self-lubricating non-rolling bearing products; precision engineered components and lubrication systems for reciprocating compressors; and heavy-duty, medium-speed diesel, natural gas and dual fuel reciprocating engines, including parts and services.

Basis of Presentation

The accompanying interim consolidated financial statements are unaudited, and certain related information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) have been omitted in accordance with Rule 10-01 of Regulation S-X. They were prepared following the same policies and procedures used in the preparation of our annual financial statements and reflect all adjustments (consisting of normal recurring adjustments) necessary for a fair statement of results for the periods presented. The Consolidated Balance Sheet as of December 31, 2012, was derived from the audited financial statements included in our annual report on Form 10-K for the year ended December 31, 2012. The results of operations for the interim periods are not necessarily indicative of the results for the fiscal year. These consolidated financial statements should be read in conjunction with our annual consolidated financial statements for the year ended December 31, 2012 included within our annual report on Form 10-K.

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amount of assets and liabilities and disclosures regarding contingent assets and liabilities at period end and the reported amounts of revenue and expenses during the reporting period. Actual results may differ from these estimates.

All significant intercompany accounts and transactions between our consolidated operations have been eliminated.

Certain prior period amounts have been revised to conform to current classifications. Cash payments of $0.4 million for the three months ended March 31, 2012 that are associated with the development or purchase of internal-use software have been presented as investing cash flows on the Consolidated Statement of Cash Flows. They were previously classified as operating cash flows. We concluded this revision was not material to the prior period’s cash flow statement and no other financial amounts or disclosures were affected.

Recently Issued Authoritative Accounting Guidance

In February 2013, accounting guidance was amended to require companies to report, in one place, information about reclassifications out of accumulated other comprehensive income. Companies are also required to present reclassifications by component when reporting changes in the accumulated other comprehensive income balances. These changes became effective prospectively in fiscal years and interim periods within those years beginning after December 15, 2012. Other than the change in presentation, there was no effect on the consolidated financial results.

2. Earnings Per Share

	Quarters Ended March 31,

	(in millions, except per share amounts)
Numerator (basic and diluted):
Net income	$	8.6	$	13.8

Diluted	$	0.39	$	0.64

As discussed further in Note 8, we previously issued Convertible Senior Debentures (the “Convertible Debentures”). Under the terms of the Convertible Debentures, upon conversion, we will settle the par amount of our obligations in cash and the remaining obligations, if any, in common shares. Pursuant to applicable accounting guidelines, we include the conversion option effect in diluted earnings per share during such periods when our average stock price exceeds the stated conversion price.

3. Inventories

	March 31, 2013			December 31, 2012
	(in millions)
Finished products	$	71.9		$	72.0
Deferred costs relating to long-term contracts		14.4			16.6
Work in process		43.6			33.4
Raw materials and supplies		37.0			36.3
		166.9			158.3
Reserve to reduce certain inventories to LIFO basis		(12.4	)		(12.4	)
Progress payments		(22.6	)		(15.1	)
Total	$	131.9		$	130.8

The deferred costs and progress payments shown in the table above relate to engine contracts accounted for under the completed contract method of accounting. In addition, we have made progress payments to our vendor on long lead time manufactured engine component parts. These payments of $9.6 million and $8.2 million as of March 31, 2013 and December 31, 2012, respectively, are included in other current assets in the accompanying Consolidated Balance Sheets.

We use the last-in, first-out (“LIFO”) method of valuing certain of our inventories. An actual valuation of inventory under the LIFO method can be made only at the end of each year based on the inventory levels and costs at that time. Accordingly, interim LIFO calculations are based on management’s estimates of expected year-end inventory levels and costs, which are subject to change until the final year-end LIFO inventory valuation.

5

4. Percentage-of-Completion Long-Term Contracts

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 our financial management and reporting systems, we are 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, we recognize revenues using the completed-contract method. We will also continue to use the completed-contract method for engines that were in production at June 30, 2011.

Progress towards completion under POC 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 recognized in the period a loss becomes likely and estimable.

Additional information regarding engine contracts accounted for under the percentage-of-completion method is as follows:

	March 31, 2013			December 31, 2012
	(in millions)
Cumulative revenues recognized on uncompleted contracts	$	96.3		$	76.9
Cumulative billings on uncompleted contracts		98.4			71.2
	$	(2.1	)	$	5.7

These amounts were included in the accompanying Consolidated Balance Sheets under the following captions:

	March 31, 2013			December 31, 2012
	(in millions)
Accounts receivable (revenue in excess of billings)	$	5.0		$	10.3
Accrued expenses (deferred revenue)		(7.1	)		(4.6	)
	$	(2.1	)	$	5.7

See Note 3 for a presentation of the deferred costs and progress payments associated with engine contracts accounted for under the completed-contract method.

7. Related Party Transactions

The historical business operations of 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. Those subsidiaries manufactured and/or sold industrial sealing products, predominately gaskets and packing, that contained encapsulated asbestos fibers. Anchor is an inactive and insolvent indirect subsidiary of Coltec Industries Inc (“Coltec”). Our subsidiaries’ exposure to asbestos litigation and their relationships with insurance carriers have been managed through another Coltec subsidiary, Garrison Litigation Management Group, Ltd. (“Garrison”). GST LLC, Anchor and Garrison are collectively referred to as “GST.”

On June 5, 2010, GST commenced an asbestos claims resolution process under Chapter 11 of the United States Bankruptcy Code, which is ongoing. The resulting deconsolidation of GST from our financial results, discussed more fully in Note 14, required certain intercompany indebtedness described below to be reflected on our Consolidated Balance Sheets.

As of March 31, 2013 and December 31, 2012, Coltec Finance Company Ltd., a wholly-owned subsidiary of Coltec, had aggregate, short-term borrowings of $17.9 million and $10.1 million, respectively, from GST’s subsidiaries in Mexico and Australia. These unsecured obligations were denominated in the currency of the lending party, and bear interest based on the applicable one-month interbank offered rate for each foreign currency involved.

Effective as of January 1, 2010, Coltec entered into an original issue amount $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 an original issue amount $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 “Notes Payable to GST”). The Notes Payable to GST 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 Notes Payable to GST 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 Notes Payable to GST as payment-in-kind (“PIK”) interest, with interest due on January 31 of each year. In conjunction with the interest payment in 2013 and 2012, PIK interest of $11.2 million and $10.7 million, respectively, was added to the principal balance of the Notes Payable to GST. 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 certain caps. The interest due under the Notes Payable to GST may be satisfied through offsets of amounts due under intercompany services agreements pursuant to which we provide certain corporate services, make available access to group insurance coverage to GST, make advances to third party providers related to payroll and certain benefit plans sponsored by GST, and permit employees of GST to participate in certain of our benefit plans.

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 our senior secured revolving credit facility described in Note 8.

We regularly transact business with GST through the purchase and sale of products. We also provide services for GST including information technology, supply chain, treasury, accounting and tax administration, legal, and human resources under a support services agreement. GST is included in our consolidated U.S. federal income tax return and certain state combined income tax returns. As the parent

8

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 income tax accounting guidance. This method generally allocates 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.

Amounts included in our financial statements arising from transactions with GST include the following:

	Financial Statement Location	Quarters Ended March 31,
		2013		2012
		(in millions)
Sales to GST	Net sales	$	6.1	$	4.6
Purchases from GST	Cost of sales	$	7.3	$	4.7
Interest expense	Interest expense	$	7.2	$	6.9

Due to GST	Accounts payable	$	6.7	$	5.0
Accrued interest	Accrued expenses	$	7.0	$	27.4

Additionally, we had outstanding foreign exchange forward contracts with GST LLC involving the Australian dollar, Canadian dollar, Mexican peso and U.S. dollar with a notional amount of $21.9 million as of March 31, 2013. These related party contracts were eliminated in consolidation prior to the deconsolidation of GST.

8. Long-Term Debt

Convertible Debentures

As of March 31, 2013, we had $172.5 million outstanding in aggregate principal amount of Convertible Debentures, originally issued in October 2005 net of an original issue discount of $61.3 million. The Convertible Debentures bear interest at the annual rate of 3.9375%, with interest due on April 15 and October 15 of each year, and will mature on October 15, 2015, unless they are converted prior to that date. The Convertible Debentures are direct, unsecured and unsubordinated obligations and rank equal in priority with all unsecured and unsubordinated indebtedness and senior in right of payment to all subordinated indebtedness. The Convertible Debentures do not contain any financial covenants.

Holders may convert the Convertible Debentures into cash and shares of our common stock, under certain circumstances described more fully in our most recent Form 10-K. As of April 1, 2013, the Convertible Debentures became convertible by holders of the Convertible Debentures. This conversion right was triggered because the closing price per share of EnPro’s common stock exceeded $43.93, or 130% of the conversion price of $33.79, for at least twenty (20) trading days during the thirty (30) consecutive trading day period ending on March 31, 2013. The Convertible Debentures will be convertible until June 30, 2013, and may be convertible thereafter if one or more of the conversion conditions is satisfied during future measurement periods. Because the Convertible Debentures are currently convertible, the principal balance less the remaining unamortized debt discount was reflected in current maturities of long-term debt as of March 31, 2013.

We used a portion of the net proceeds from the sale of the Convertible 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 stock holders from conversion of the Convertible Debentures and have the effect to us of increasing the conversion price of the Convertible Debentures to $46.78 per share.

9

The debt discount, $21.7 million as of March 31, 2013, is being amortized through interest expense until the maturity date of October 15, 2015, resulting in an effective interest rate of approximately 9.5%. Interest expense related to the Convertible Debentures for the quarters ended March 31, 2013 and 2012 includes $1.7 million of contractual interest coupon in both periods and $1.8 million and $1.7 million, respectively, of debt discount amortization.

Credit Facility

Our primary U.S. operating subsidiaries, other than GST LLC, have a senior secured revolving credit facility with a maximum availability of $175 million. 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 real property elected to be pledged, 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 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, the Convertible Debentures are paid in full, refinanced on certain terms or defeased, in which case the facility will mature on March 30, 2016. The terms of the facility, including fees and customary covenants and restrictions, are described more fully in our most recent Form 10-K.

The borrowing availability at March 31, 2013, under our senior secured revolving credit facility was $66.3 million after giving consideration to $3.8 million of letters of credit outstanding and $56.0 million of outstanding revolver borrowings.

9. Pensions and Postretirement Benefits

The components of net periodic benefit cost for the Company’s U.S. and foreign defined benefit pension and other postretirement plans for the quarters ended March 31, 2013 and 2012, are as follows:

	Quarters Ended March 31,
	Pension Benefits						Other Benefits
	2013			2012			2013		2012
	(in millions)
Service cost	$	1.7		$	1.2		$	0.2	$	0.2
Interest cost		2.7			2.5			0.1		0.1
Expected return on plan assets		(3.1	)		(2.2	)		—		—
Amortization of prior service cost		—			0.1			—		—
Net loss component		2.2			2.2			—		—
Deconsolidation of GST		(0.5	)		(0.6	)		—		—
Net periodic benefit cost	$	3.0		$	3.2		$	0.3	$	0.3

In the three months ended March 31, 2013, we contributed $7.2 million to our U.S. defined benefit pension plans and anticipate additional contributions of approximately $12 million prior to December 31, 2013.

10. Derivative Instruments

We use derivative financial instruments to manage our exposure to various risks. The use of these financial instruments modifies the exposure with the intent of reducing our risk. We do not use financial instruments for trading purposes, nor do we use leveraged financial instruments. The counterparties to these contractual arrangements are major financial institutions and GST LLC as described in Note 7. We use multiple financial institutions for derivative contracts to minimize the

10

concentration of credit risk. The current accounting rules require derivative instruments, excluding certain contracts that are issued and held by a reporting entity that are both indexed to its own stock and classified in shareholders’ equity, be reported in the Consolidated Balance Sheets at fair value and that changes in a derivative’s fair value be recognized currently in earnings unless specific hedge accounting criteria are met.

We are exposed to foreign currency risks that arise from normal business operations. These risks include the translation of local currency balances on our foreign subsidiaries’ balance sheets, intercompany loans with foreign subsidiaries and transactions denominated in foreign currencies. We strive to control our exposure to these risks through our normal operating activities and, where appropriate, through derivative instruments. We have entered into contracts to hedge forecasted transactions occurring at various dates through December 2014 that are denominated in foreign currencies. The notional amount of foreign exchange contracts hedging foreign currency transactions was $101.1 million and $130.4 million at March 31, 2013 and December 31, 2012, respectively.

Prior to 2013, we applied cash flow hedge accounting to certain of our foreign currency derivatives. We elected to discontinue this accounting treatment in the first quarter of 2013, consequently, all gains and losses that had been deferred in accumulated other comprehensive loss at December 31, 2012 were reclassified to income in the quarter ended March 31, 2013. See Note 13 for additional information. The notional amounts of all of our foreign exchange contracts were recorded at their fair market value as of March 31, 2013 with changes in market value recorded in income. The earnings impact of any foreign exchange contract that is specifically related to the purchase of inventory is recorded in cost of sales and the changes in market value of all other contracts are recorded in selling, general and administrative expense in the Consolidated Statements of Operations. The balances of derivative assets are recorded in other current assets and the balances of derivative liabilities are recorded in accrued expenses in the Consolidated Balance Sheets.

11. Business Segment Information

We have three reportable segments. The Sealing Products segment 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, polytetrafluoroethylene (“PTFE”) products, conveyor belting, and sheeted rubber products.

The Engineered Products segment manufactures self-lubricating non-rolling bearing products, aluminum blocks for hydraulic applications, and precision engineered components and lubrication systems for reciprocating compressors and provides repair services for those compressors.

The Engine Products and Services segment manufactures and services heavy-duty medium-speed diesel, natural gas and dual fuel reciprocating engines.

Our reportable segments are managed separately based on differences in their products and services and their end-customers. Segment profit is total segment revenue reduced by operating expenses and restructuring and other costs identifiable with the segment. Corporate expenses include general corporate administrative costs. Expenses not directly attributable to the segments, corporate expenses, net interest expense, gains and losses related to the sale of assets, impairments, 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.

12. Fair Value Measurements

We utilize a fair value hierarchy that categorizes the inputs to valuation techniques used to measure fair value into three broad levels. The following is a brief description of those three levels:

• Level 1: Observable inputs such as quoted prices in active markets for identical assets or liabilities.

• Level 2: Inputs other than quoted prices that are observable for the asset or liability, either directly or indirectly. These include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active.

• Level 3: Unobservable inputs that reflect the reporting entity’s own assumptions.

12

Assets and liabilities measured at fair value on a recurring basis are summarized as follows:

Our cash equivalents and deferred compensation assets and liabilities are classified within Level 1 of the fair value hierarchy because they are valued using quoted market prices. The fair value for the guaranteed investment contract is based on quoted market prices for outstanding bonds of the insurance company issuing the contract. The fair values for foreign currency derivatives are based on quoted market prices from various banks for similar instruments.

13

The carrying values of our significant financial instruments reflected in the Consolidated Balance Sheets approximated their respective fair values except for the following instruments:

	March 31, 2013				December 31, 2012
	Carrying Value		Fair Value		Carrying Value		Fair Value
	(in millions)
Long-term debt	$	208.0	$	332.5	$	185.3	$	261.6
Notes payable to GST	$	259.3	$	282.6	$	248.1	$	268.2

The fair values for long-term debt are based on quoted market prices, but these would be considered Level 2 computations because the market is not active. The notes payable to GST computations would be considered Level 2 since they are based on rates available to us for debt with similar terms and maturities.

13. Accumulated Other Comprehensive Loss

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

On June 5, 2010 (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”). 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 typically would establish a trust to which all asbestos claims would 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.

GST’s financial results were included in our consolidated results through June 4, 2010, the day prior to the Petition Date. However, GAAP requires that 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 and its subsidiaries were with EnPro, 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 on June 4, 2010. 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. This investment is 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.

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 asbestos personal injury claim, i.e., 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 final 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 the 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 Future Claimants’ Representative (the “FCR”) and is unlikely to be approved in its current form. The Claimants’ Committee and FCR have announced their intention to file a competing proposed plan of reorganization.

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 potential proposed plan of reorganization. The estimation trial is scheduled to occur in the third quarter of 2013.

15

Through March 31, 2013, GST has recorded cumulative reorganization costs, including fees and expenses, in the Chapter 11 case totaling $67.8 million. The total includes $36.5 million for fees and expenses of GST’s counsel and experts; $25.4 million for fees and expenses of counsel and experts for the asbestos claimants’ committee, and $5.9 million for the fees and expenses of the future claims representative and his counsel and experts. GST recorded $10.4 million of those case-related fees and expenses in the first three months of 2013, compared to $7.3 million in the first three months of 2012.

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 in GST.

(A) Liabilities subject to compromise include pre-petition unsecured claims which may be resolved at amounts different from those recorded in the condensed combined balance sheets. Liabilities subject to compromise consist principally of asbestos-related claims. GST has undertaken to project the number and ultimate cost of all present and future bodily injury claims expected to be asserted, based on actuarial principles, and to measure probable and estimable liabilities under generally accepted accounting principles. GST has accrued $466.8 million as of March 31, 2013. The estimate indicated for those asbestos-related claims reflects the point in a wide range of possible outcomes determined based on historical facts and circumstances prior to the Petition Date as our estimate of the cost to resolve asbestos-related personal injury cases and claims against GST as they would have been resolved in the state courts or by settlements

17

over a ten-year period from April 1, 2010 through March 31, 2020. GST adjusts this estimate to reflect payments of previously accrued but unpaid legal fees and to reflect the results of appeals. Otherwise, GST does not expect to adjust the estimate unless developments in the Chapter 11 proceeding provide a reasonable basis for a revised estimate. GST intends to use the claims resolution process in Chapter 11 to determine the validity and ultimate amount of its aggregate liability for asbestos-related claims. Due to the uncertainties of asbestos-related litigation and the Chapter 11 process, GST’s ultimate liability could differ materially from the recorded liability. See Note 15, “Commitments and Contingencies – Asbestos.”

15. Commitments and Contingencies

General

A description of 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. Expenses 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 manufacturing 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 or more of our subsidiaries are involved with various remediation activities at 14 sites where the future cost per site for us or our subsidiary is expected to exceed $100 thousand. Investigations have been completed for 11 sites and are in progress at the other three 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.

Our policy is to accrue environmental investigation and remediation costs when it is probable that a liability has been incurred and the amount can be reasonably estimated. The measurement of the liability is based on an evaluation of currently available facts with respect to each individual situation and takes into consideration factors such as existing technology, presently enacted laws and regulations and prior experience in remediation of contaminated sites. Liabilities are established for all sites based on these factors. As assessments and remediation progress at individual sites, these liabilities are reviewed periodically and adjusted to reflect additional technical data and legal information. As of March 31, 2013 and December 31, 2012, we had accrued liabilities of $10.1 million and $11.3 million, respectively, for estimated future expenditures relating to environmental contingencies. These amounts have been recorded on an undiscounted basis in the Consolidated Balance Sheets. 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.

We believe that our accruals for specific environmental liabilities are adequate for those liabilities based on currently available information. Actual costs to be incurred in future periods may vary from estimates because of the inherent uncertainties in evaluating environmental exposures due to unknown and changing conditions, changing government regulations and legal standards regarding liability. In

18

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, some of which are included in the 14 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 the section entitled “Crucible Steel Corporation a/k/a Crucible, Inc.” in this footnote for additional information.

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 our 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, 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.

In conjunction with the closure of a Crucible plant in the early 1980s, Coltec was required to fund a trust for retiree medical benefits for certain employees at the plant. This trust (the “Benefits Trust”) pays for these retiree medical benefits on an ongoing basis. Coltec has no ownership interest in the Benefits Trust, and thus the assets and liabilities of this trust are not included in our Consolidated Balance Sheets. Under the terms of the Benefits Trust agreement, the trustees retained an actuary to assess the adequacy of the assets in the Benefits Trust in 1995 and 2005. A third and final actuarial report will be required in 2015. The actuarial reports in 1995 and 2005 determined that the Benefits Trust has sufficient assets to fund the payment of future benefits. We own a guaranteed investment contract with a current value of $2.6 million, which is being held in a special account in case of a shortfall in the Benefits Trust.

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, in addition to those mentioned previously related to Coltec’s period of ownership of Crucible. Based on Coltec’s prior ownership of Crucible, we may have certain additional 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.

19

Warranties

We provide warranties on many of our products. The specific terms and conditions of these warranties vary depending on the product and the market in which the product is sold. We record a liability based upon estimates of the costs we may incur under our warranties after a review of historical warranty experience and information about specific warranty claims. Adjustments are made to the liability as claims data and historical experience warrant.

Changes in the carrying amount of the product warranty liability for the three months ended March 31, 2013 and 2012 are as follows:

	2013			2012
	(in millions)
Balance at beginning of year	$	4.1		$	3.5
Charges to expense		0.8			0.7
Settlements made (primarily payments)		(0.9	)		(0.8	)
Balance at end of period	$	4.0		$	3.4

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 of such plaintiffs. GST LLC and Anchor manufactured and/or sold industrial sealing products that contained encapsulated asbestos fibers. Other subsidiaries of the company 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 neither we nor any of our subsidiaries other than 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.

Subsidiary Chapter 11 Filing and Effect. On the Petition Date, GST LLC, Garrison and Anchor filed voluntary petitions for reorganization under Chapter 11 of the United States Bankruptcy Code in the Bankruptcy Court. The filings were the initial step in a claims resolution process, which is ongoing. See Note 14 for additional information about this process and its impact on us.

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

20

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, 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 its quarterly reports for the first and second quarters of 2010.

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 500) have not responded to the questionnaire at all, many others (more than 1,900) reflect claims where the claimants do not have mesothelioma, have acknowledged that they cannot establish exposure to GST products, their claims were dismissed, settled or withdrawn, their claims were duplicates of other filed claims, or were closed or inactive. Still others have responded to the questionnaire but their responses are deficient in some material respect. As a result of this process, less than 3,300 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 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 March 31, 2013, three additional GST LLC appeals are pending from adverse decisions totaling $2.4 million.

21

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 March 31, 2013 we had $141.1 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 $54.0 million since the Petition Date. Of the $141.1 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 $1.1 million (1%) to be of moderate quality because the insurance policies are written with various London market carriers. Of the $141.1 million, $105.1 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 $141.1 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 $141.1 million is in addition to the $0.8 million collected in the first three months of 2013. 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:

2013 – $21.2 million (in the remaining nine months of 2013)

2014 – $21.2 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 and may receive additional payments from insolvent carriers in the future. No anticipated insolvent carrier collections are included in the $141.1 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

22

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 March 31, 2013 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. 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 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 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.

Overview and Outlook

Overview. We are a leader in the design, development, manufacture and marketing of proprietary engineered industrial products. We have 61 primary manufacturing facilities located in 12 countries, including the United States.

24

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 highly demanding applications, 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, precision engineered components, and lubrication systems and repair services 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 the Company’s subsidiary, Coltec Industries Inc (“Coltec”), principally 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. 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 and in Note 14 to our Consolidated Financial Statements.

On June 5, 2010 (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”). GST LLC, Anchor and Garrison are sometimes referred to jointly as “GST” in this report. The filings were the initial step in a claims resolution process, which is ongoing. GST LLC is one of the businesses in our broader Garlock group and, prior to the Petition Date, was included in our Sealing Products segment. GST LLC and its subsidiaries operate five primary 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 and supervision. All pending litigation against GST is stayed during the process. We address our actions to permanently resolve GST LLC’s asbestos litigation, and provide an update on its claims resolution process, in this Management’s Discussion and Analysis of Financial Condition and Results of Operation in the “Garlock Sealing Technologies LLC and Garrison Litigation Management Group, Ltd.” and “Contingencies –Subsidiary Bankruptcy” sections.

25

The financial results of GST and subsidiaries were 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 March 31, 2013 is 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 14 to our Consolidated Financial Statements for condensed financial information for GST and subsidiaries.

In April 2012, the Company acquired Motorwheel Commercial Vehicle Systems, Inc. (“Motorwheel”). Motorwheel is a leading U.S. manufacturer of lightweight brake drums for heavy-duty trucks and other commercial vehicles. Motorwheel also sells wheel-end component assemblies for the heavy-duty market, sells fasteners for wheel-end applications and provides related services to its customers, including product development, testing and certification. The business operates manufacturing facilities in Chattanooga, Tennessee, and Berea, Kentucky. Motorwheel is managed as part of the Stemco operations in the Sealing Products segment.

We paid for the Motorwheel acquisition with approximately $85 million of cash, which was funded by additional borrowings from our revolving credit facility. We allocated the purchase price of the business to the assets acquired and liabilities assumed based on their estimated fair values. The excess of the purchase price over the identifiable assets acquired less the liabilities assumed was reflected as goodwill.

Outlook.

Although we see no indication of sustained improvement, we expect seasonal growth in some markets during the second quarter. These seasonal factors are likely to support an increase in sales compared to the first quarter. Profits and profit margins should improve as volumes increase and as we continue to benefit from previously implemented cost reductions and efficiency programs. Longer term, we remain cautious. In North America, we believe low levels of growth are likely in most of our markets during 2013. In Europe, we anticipate little if any growth as weak economic conditions persist in many of our markets. In these circumstances, we will continue to ensure that our cost structure is in line with activity levels in all markets.

Our effective tax rate is directly impacted 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 for the remainder of 2013 will be between 29% and 32%. Tax expense in 2013 is favorably impacted by the January passage of the American Taxpayer Relief Act of 2012, which retroactively extended various tax provisions applicable to the Company. These include the research and development credit, certain employment credits, and an exclusion for passive income earned by controlled foreign corporations. Other 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

26

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.

Our U.S. defined benefit plans continue to be underfunded. Based on currently available data, which is subject to change, we have estimated we will be required to contribute approximately $19 million to our U.S. defined benefit pension plans in 2013, of which $7.2 million was contributed during the first three months of 2013. Additional significant contributions 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. We estimate annual pension expense for the full year of 2013 will be $11.1 million, which would be $1.3 million less than in 2012. The expected 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 plan to evaluate additional acquisition opportunities in 2013. However, the effects of such acquisitions, if any, cannot be predicted and therefore are not reflected in this outlook.

We address our outlook regarding 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.” and “Subsidiary Bankruptcy” sections.

First Quarter of 2013 Compared to the First Quarter of 2012

Sales of $286.9 million in the first quarter of 2013 decreased 8% from $311.5 million in the first quarter of 2012. The following table summarizes the impact of acquisitions, foreign currency, and engine revenues, by segment:

Sales	Percent Change 1st Quarter 2013 vs. 1st Quarter  2012
increase/(decrease)	Acquisitions			Foreign Currency			Engine Revenue			Other			Total
EnPro Industries, Inc.		4	%		0	%		(5	%)		(7	%)		(8	%)
Sealing Products		8	%		0	%		n/a			(10	%)		(2	%)
Engineered Products		0	%		0	%		n/a			(9	%)		(9	%)
Engine Products & Services		0	%		0	%		(23	%)		3	%		(20	%)

Following are the drivers regarding changes in sales for the first quarter of 2013 compared to the same period in 2012:

• Our acquisition of Motorwheel – acquired in April 2012 and included in the Sealing Products segment.

• Lower engine revenues in the Engine Products & Services segment resulting from the sale of four engines in the prior year period that were accounted for under the completed contract method of accounting, while no engines accounted for under that method were sold in the first quarter of 2013.

• Lower volumes across the Sealing Products and Engineered Products segments due to soft markets, which are significantly below the levels of early 2012.

• Sales and segment profits in the first quarter of 2013 as compared to the same period in 2012 were not impacted by foreign exchange rate fluctuations.

See below for additional discussion on segment sales and segment profits.

There were no significant changes in amount or composition of Corporate and Other expenses as compared to the first quarter of 2012.

Net interest expense in the first quarter of 2013 increased $0.4 million as compared to the first quarter of 2012, primarily due to higher borrowings against the senior secured revolving credit facility.

We recorded income tax expense of $1.1 million on pre-tax income from continuing operations of $9.7 million in the first quarter of 2013, resulting in an unusually low effective tax rate of 11.4%. In January 2013, the United States Congress passed the American Taxpayer Relief Act of 2012, retroactively extending previously expired tax provisions such as the deduction for domestic production activities, credits for research and development, certain employment credits, and other tax provisions applicable to us. Consequently, results from the first quarter of 2013 include a tax benefit which significantly reduces our effective tax rate for the quarter, and to a lesser extent will reduce the annual effective tax rate for 2013. During the first quarter of 2012, our effective tax rate was 36.2% as we recorded an income tax expense of $7.8 million on pre-tax income of $21.6 million. Our effective tax rate is generally lower than U.S. statutory rates primarily due to the earnings in lower rate foreign jurisdictions where a significant portion of our income is taxed.

28

Net income was $8.6 million, or $0.39 per share, in the first quarter of 2013 compared to net income of $13.8 million, or $0.64 per share, in the same quarter of 2012. Earnings per share are expressed on a diluted basis.

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

Sealing Products. Sales of $146.6 million in the first quarter of 2013 were 2% lower than the $149.5 million reported in the same quarter of 2012. Excluding the effect of the Motorwheel acquisition, sales were down 10% or $15.0 million due to lower volumes, primarily in the semiconductor industry ($4.9 million), North American heavy-duty truck markets ($4.4 million), and European water and waste water infrastructure markets ($3.1 million).

Segment profit of $21.3 million in the first quarter of 2013 decreased 5% from $22.5 million reported in the first quarter of 2012. Excluding the effects of the Motorwheel acquisition, profit was down $3.2 million or 14%. The decrease in segment profit was primarily the result of lower sales volumes across the segment and a change in sales mix at Stemco as sales of higher margin after-market products declined. These declines were partially offset by the release of an acquisition earnout provision of $1.5 million. Operating margins for the segment declined from 15.1% in 2012 to 14.5% in 2013.

Engineered Products. Sales of $91.8 million in the first quarter of 2013 were 9% lower than the $100.6 million reported in the first quarter of 2012. The decline in revenue is primarily a result of lower demand in the European ($4.4 million) and North American ($1.1 million) automotive markets, and in the Canadian natural gas market ($1.3 million). These declines were partially offset by higher export sales from European operations.

Segment profit in the first quarter of 2013 was $5.8 million, which compares to $9.0 million in the same quarter last year. Reduced segment profit is primarily due to lower sales volumes, specifically at GGB, which is sensitive to volume declines because of its fixed cost structure. We also experienced higher costs at GGB, which were only partially offset by price increases. CPI’s selling, general, and administrative costs were $2.1 million lower than in the first quarter of 2012 as a result of the 2012 restructuring efforts. Operating margins for the segment were 6.3%, which declined from the 8.9% reported in the comparable quarter last year.

Engine Products and Services. Sales of $49.4 million in the first quarter of 2013 were 20% lower than the $62.0 million reported in the first quarter of 2012. The decrease in sales was a result of lower engine revenues driven by a shipment of 4 engines in the first quarter of 2012 valued at $18.4 million, which was accounted for under the completed contract method of accounting. There were no sales of engines accounted for under the completed contract method during the first quarter of 2013. This decline was offset by higher revenue recognized on percentage of completion contracts of $5.3 million. Parts and services sales were up $1.6 million on strong year-over-year sales of new environmental upgrade products.

The segment reported a profit of $4.8 million in the first quarter of 2013 compared to $11.8 million in the first quarter of 2012. The quarter-over-quarter decline in segment profit was primarily due to lower sales, a less profitable product mix as sales of environmental upgrade packages increased and a low margin engine refurbishment project was completed, and a change in accounting treatment for foreign exchange hedges of $0.8 million. Operating margins for the segment decreased from 19.0% in 2012 to 9.7% in 2013.

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 acquisition opportunities could exceed our cash balance at the time of closing. Should we need additional capital, we have resources available, which are discussed in this section under the heading “Capital Resources.”

As of March 31, 2013, we held $1 million cash or cash equivalents in the United States and $47 million of 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 could be required to accrue and pay U.S. taxes to repatriate these funds. However, 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 consumed cash in the amount of $17.8 million in the first quarter of 2013 compared to cash generated of $3.4 million in the same period last year. The change as compared to the first quarter of 2012 is primarily driven by lower segment results of approximately $11 million, higher pension payments of $7.2 million and higher taxes paid of $5.4 million.

Investing activities used $15.4 million of cash during the first quarter of 2013, primarily to fund the acquisition of a building previously under lease and enterprise resource and planning system implementations. Investing activities used $6.4 million of cash in the first quarter of 2012.

Financing activities provided $30.2 million in cash in the first quarter of 2013, including net borrowings on the senior secured revolving credit facility of approximately $22 million and net proceeds from short term borrowings of $7.4 million. Financing activities in the first quarter of 2012 provided cash of $11.1 million, including net borrowings on the senior secured revolving credit facility of $11.4 million.

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 currently bear interest at a rate equal to, at our option, either: (1) a base/prime rate plus 0.75%, or (2) the adjusted one, two, three or six-month LIBOR

30

rate plus 1.75%. Future pricing under the credit facility at any particular time will be 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 will range from 0.75% to 1.25% for base/prime rate loans and from 1.75% to 2.25% for LIBOR loans. 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 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 borrowing availability at March 31, 2013, under our senior secured revolving credit facility was $66.3 million after giving consideration to $3.8 million of letters of credit outstanding and $56.0 million of revolver borrowings.

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. The debentures do not contain any financial covenants. Holders may convert the debentures into cash and shares of our common stock, under certain circumstances described more fully in our most recent Form 10-K.

As of April 1, 2013, the debentures became convertible by holders of the debentures. This conversion right was triggered because the closing price per share of EnPro’s common stock exceeded $43.93, or 130% of the conversion price of $33.79, for at least twenty (20) trading days during the thirty (30) consecutive trading day period ending on March 31, 2013. The debentures will be convertible until June 30, 2013, and may be convertible thereafter if one or more of the conversion conditions is satisfied during future measurement periods. Because the debentures are currently convertible, the principal balance less the remaining unamortized debt discount was reflected in current maturities of long-term debt as of March 31, 2013.

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

31

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 stock holders from conversion of the debentures and have the effect to us of increasing the conversion price of the debentures to $46.78 per share.

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 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” in our annual report on Form 10-K for the year ended December 31, 2012.

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

32

accounting will be determined based upon the applicable circumstances and facts at such time, including the terms of any plan of reorganization. See Note 14 to our Consolidated Financial Statements for condensed financial information for GST and subsidiaries.

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 March 31, 2013, this amount was $34.1 million. This receivable is expected to be collected at a future date.

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’, operating activities 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 14 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.

Critical Accounting Policies and Estimates

Please refer to our annual report on Form 10-K for the fiscal year ended December 31, 2012, for a complete list of our critical accounting policies and estimates.

Recently Issued Accounting Pronouncement

See Note 1 to our Consolidated Financial Statements in this Form 10-Q for a description of new accounting pronouncements.

Contingencies

General

A description of environmental, asbestos and other legal matters against certain of our subsidiaries is included in this section in more detail. 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.

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 manufacturing

33

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 or more of our subsidiaries are involved with various remediation activities at 14 sites where the future cost per site for us or our subsidiary is expected to exceed $100 thousand. Investigations have been completed for 11 sites and are in progress at the other three sites. The majority of these sites relate to remediation projects at former operating facilities that were sold or closed and primarily deal with soil and groundwater contamination.

As of March 31, 2013 and December 31, 2012, we had accrued liabilities of $10.1 million and $11.3 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, some of which are included in the 14 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 15 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 15 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, which is ongoing. 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 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.

35

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.

Through March 31, 2013, GST has recorded Chapter 11 case-related fees and expenses totaling $67.8 million. The total includes $36.5 million for fees and expenses of GST’s counsel and experts; $25.4 million for fees and expenses of counsel and experts for the asbestos claimants’ committee, and $5.9 million for the fees and expenses of the future claims representative and his counsel and experts. GST recorded $10.4 million of those case-related fees and expenses in the first three months of 2013 compared to $7.3 million in the first three months of 2012. 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 the estimation trial, and claimant representatives’ efforts to extend GST’s liability to affiliates.

See the additional information provided earlier under the heading “Garlock Sealing Technologies LLC and Garrison Litigation Management Group, Ltd.”, the discussion under the heading “Asbestos”, which follows, and Notes 14 and 15 to our Consolidated Financial Statements.

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 of such plaintiffs. GST LLC and Anchor manufactured and/or sold industrial sealing products that contained encapsulated asbestos fibers. Other subsidiaries of the Company 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 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

36

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 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 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, which is ongoing.

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, 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.

37

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 500) have not responded to the questionnaire at all, many others (more than 1,900) reflect claims where the claimants do not have mesothelioma, have acknowledged that they cannot establish exposure to GST products, their claims were dismissed, settled or withdrawn, their claims were duplicates of other filed claims, or were closed or inactive. Still others have responded to the questionnaire but their responses are deficient in some material respect. As a result of this process, less than 3,300 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 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 March 31, 2013, 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

38

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 March 31, 2013, we had $141.1 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 $54.0 million since the Petition Date. Of the $141.1 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 $1.1 million (1%) to be of moderate quality because the insurance policies are written with various London market carriers. Of the $141.1 million, $105.1 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 $141.1 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 $141.1 million is in addition to the $0.8 million collected in the first three months of 2013. 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:

2013 – $21.2 million (in the remaining nine months of 2013)

2014 – $21.2 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 and may receive additional payments from insolvent carriers in the future. No anticipated insolvent carrier collections are included in the $141.1 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.

39

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 March 31, 2013 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 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 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.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

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 impact our financial condition, results of operations and cash flows. We manage our exposure to these and other market risks through regular 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. For information about our interest rate risk, see “Quantitative and Qualitative Disclosures about Market Risk – Interest Rate Risk” in our annual report on Form 10-K for the year ended December 31, 2012, and the following section.

40

Foreign Currency Risk

We are exposed to foreign currency risks that arise 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 March 31, 2013:

Transaction Type	Notional Amount Outstanding in Millions of U.S. Dollars (USD)		Maturity Dates	Exchange Rate Ranges

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.

Item 4. 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 Securities Exchange Act of 1934 (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.

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.

41

In addition, no change in our internal control over financial reporting has occurred during the quarter ended March 31, 2013, that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

OTHER INFORMATION

Item 1. Legal Proceedings.

A description of environmental, asbestos and other legal matters is included in Note 15 to the Consolidated Financial Statements in this report, which is incorporated herein by reference. A description of the bankruptcy proceeding filed by certain of the Company’s subsidiaries, and an update on and discussion of the implications of that proceeding and related activities are included in Note 7 and Note 14 to the Consolidated Financial Statements in this report, which are incorporated herein by reference. Those matters are also discussed in Management’s Discussion and Analysis of Financial Condition and Results of Operations.

We believe that 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.

Coltec furnished these shares in exchange for management and other services provided by EnPro. These shares were valued at a price of $50.89 per share, the average of the high and low trading price of our common stock on March 28, 2013. We do not consider the transfer of shares from Coltec in this context to be pursuant to a publicly announced plan or program.

The deferred costs and progress payments shown in the table above relate to engine contracts accounted for under the completed contract method of accounting. In addition, we have made progress payments to our vendor on long lead time manufactured engine component parts. These payments of $9.6 million and $8.2 million as of March 31, 2013 and December 31, 2012, respectively, are included in other current assets in the accompanying Consolidated Balance Sheets.

We use the last-in, first-out (“LIFO”) method of valuing certain of our inventories. An actual valuation of inventory under the LIFO method can be made only at the end of each year based on the inventory levels and costs at that time. Accordingly, interim LIFO calculations are based on management’s estimates of expected year-end inventory levels and costs, which are subject to change until the final year-end LIFO inventory valuation.

Total liabilities and shareholder’s equity	$	833.7	$	835.4

(A) Liabilities subject to compromise include pre-petition unsecured claims which may be resolved at amounts different from those recorded in the condensed combined balance sheets. Liabilities subject to compromise consist principally of asbestos-related claims. GST has undertaken to project the number and ultimate cost of all present and future bodily injury claims expected to be asserted, based on actuarial principles, and to measure probable and estimable liabilities under generally accepted accounting principles. GST has accrued $466.8 million as of March 31, 2013. The estimate indicated for those asbestos-related claims reflects the point in a wide range of possible outcomes determined based on historical facts and circumstances prior to the Petition Date as our estimate of the cost to resolve asbestos-related personal injury cases and claims against GST as they would have been resolved in the state courts or by settlements over a ten-year period from April 1, 2010 through March 31, 2020. GST adjusts this estimate to reflect payments of previously accrued but unpaid legal fees and to reflect the results of appeals. Otherwise, GST does not expect to adjust the estimate unless developments in the Chapter 11 proceeding provide a reasonable basis for a revised estimate. GST intends to use the claims resolution process in Chapter 11 to determine the validity and ultimate amount of its aggregate liability for asbestos-related claims. Due to the uncertainties of asbestos-related litigation and the Chapter 11 process, GST’s ultimate liability could differ materially from the recorded liability. See Note 15, “Commitments and Contingencies – Asbestos.”

Overview, Basis of Presentation and Recently Issued Authoritative Accounting Guidance

Overview, Basis of Presentation and Recently Issued Authoritative Accounting Guidance

1. Overview, Basis of Presentation and Recently Issued Authoritative Accounting Guidance

Overview

EnPro Industries, Inc. (“we,” “us,” “our,” “EnPro” or the “Company”) is a leader in the design, development, manufacture and marketing of proprietary engineered industrial products that primarily include: sealing products; self-lubricating non-rolling bearing products; precision engineered components and lubrication systems for reciprocating compressors; and heavy-duty, medium-speed diesel, natural gas and dual fuel reciprocating engines, including parts and services.

Basis of Presentation

The accompanying interim consolidated financial statements are unaudited, and certain related information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) have been omitted in accordance with Rule 10-01 of Regulation S-X. They were prepared following the same policies and procedures used in the preparation of our annual financial statements and reflect all adjustments (consisting of normal recurring adjustments) necessary for a fair statement of results for the periods presented. The Consolidated Balance Sheet as of December 31, 2012, was derived from the audited financial statements included in our annual report on Form 10-K for the year ended December 31, 2012. The results of operations for the interim periods are not necessarily indicative of the results for the fiscal year. These consolidated financial statements should be read in conjunction with our annual consolidated financial statements for the year ended December 31, 2012 included within our annual report on Form 10-K.

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amount of assets and liabilities and disclosures regarding contingent assets and liabilities at period end and the reported amounts of revenue and expenses during the reporting period. Actual results may differ from these estimates.

All significant intercompany accounts and transactions between our consolidated operations have been eliminated.

Certain prior period amounts have been revised to conform to current classifications. Cash payments of $0.4 million for the three months ended March 31, 2012 that are associated with the development or purchase of internal-use software have been presented as investing cash flows on the Consolidated Statement of Cash Flows. They were previously classified as operating cash flows. We concluded this revision was not material to the prior period’s cash flow statement and no other financial amounts or disclosures were affected.

Recently Issued Authoritative Accounting Guidance

In February 2013, accounting guidance was amended to require companies to report, in one place, information about reclassifications out of accumulated other comprehensive income. Companies are also required to present reclassifications by component when reporting changes in the accumulated other comprehensive income balances. These changes became effective prospectively in fiscal years and interim periods within those years beginning after December 15, 2012. Other than the change in presentation, there was no effect on the consolidated financial results.

Business Segment Information

11. Business Segment Information

We have three reportable segments. The Sealing Products segment 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, polytetrafluoroethylene (“PTFE”) products, conveyor belting, and sheeted rubber products.

The Engineered Products segment manufactures self-lubricating non-rolling bearing products, aluminum blocks for hydraulic applications, and precision engineered components and lubrication systems for reciprocating compressors and provides repair services for those compressors.

The Engine Products and Services segment manufactures and services heavy-duty medium-speed diesel, natural gas and dual fuel reciprocating engines.

Our reportable segments are managed separately based on differences in their products and services and their end-customers. Segment profit is total segment revenue reduced by operating expenses and restructuring and other costs identifiable with the segment. Corporate expenses include general corporate administrative costs. Expenses not directly attributable to the segments, corporate expenses, net interest expense, gains and losses related to the sale of assets, impairments, 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.

Segment operating results and other financial data for the quarters ended March 31, 2013 and 2012 were as follows:

Fair Value Measurements

Fair Value Measurements

12. Fair Value Measurements

We utilize a fair value hierarchy that categorizes the inputs to valuation techniques used to measure fair value into three broad levels. The following is a brief description of those three levels:

• Level 1: Observable inputs such as quoted prices in active markets for identical assets or liabilities.

• Level 2: Inputs other than quoted prices that are observable for the asset or liability, either directly or indirectly. These include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active.

• Level 3: Unobservable inputs that reflect the reporting entity’s own assumptions.

Assets and liabilities measured at fair value on a recurring basis are summarized as follows:

	Fair Value Measurements as of March 31, 2013

Foreign currency derivatives		0.9		—		0.9		—
	$	7.4	$	6.5	$	0.9	$	—

Our cash equivalents and deferred compensation assets and liabilities are classified within Level 1 of the fair value hierarchy because they are valued using quoted market prices. The fair value for the guaranteed investment contract is based on quoted market prices for outstanding bonds of the insurance company issuing the contract. The fair values for foreign currency derivatives are based on quoted market prices from various banks for similar instruments.

The carrying values of our significant financial instruments reflected in the Consolidated Balance Sheets approximated their respective fair values except for the following instruments:

	March 31, 2013				December 31, 2012
	Carrying Value		Fair Value		Carrying Value		Fair Value
	(in millions)
Long-term debt	$	208.0	$	332.5	$	185.3	$	261.6
Notes payable to GST	$	259.3	$	282.6	$	248.1	$	268.2

The fair values for long-term debt are based on quoted market prices, but these would be considered Level 2 computations because the market is not active. The notes payable to GST computations would be considered Level 2 since they are based on rates available to us for debt with similar terms and maturities.

Related Party Transactions

7. Related Party Transactions

The historical business operations of 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. Those subsidiaries manufactured and/or sold industrial sealing products, predominately gaskets and packing, that contained encapsulated asbestos fibers. Anchor is an inactive and insolvent indirect subsidiary of Coltec Industries Inc (“Coltec”). Our subsidiaries’ exposure to asbestos litigation and their relationships with insurance carriers have been managed through another Coltec subsidiary, Garrison Litigation Management Group, Ltd. (“Garrison”). GST LLC, Anchor and Garrison are collectively referred to as “GST.”

On June 5, 2010, GST commenced an asbestos claims resolution process under Chapter 11 of the United States Bankruptcy Code, which is ongoing. The resulting deconsolidation of GST from our financial results, discussed more fully in Note 14, required certain intercompany indebtedness described below to be reflected on our Consolidated Balance Sheets.

As of March 31, 2013 and December 31, 2012, Coltec Finance Company Ltd., a wholly-owned subsidiary of Coltec, had aggregate, short-term borrowings of $17.9 million and $10.1 million, respectively, from GST’s subsidiaries in Mexico and Australia. These unsecured obligations were denominated in the currency of the lending party, and bear interest based on the applicable one-month interbank offered rate for each foreign currency involved.

Effective as of January 1, 2010, Coltec entered into an original issue amount $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 an original issue amount $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 “Notes Payable to GST”). The Notes Payable to GST 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 Notes Payable to GST 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 Notes Payable to GST as payment-in-kind (“PIK”) interest, with interest due on January 31 of each year. In conjunction with the interest payment in 2013 and 2012, PIK interest of $11.2 million and $10.7 million, respectively, was added to the principal balance of the Notes Payable to GST. 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 certain caps. The interest due under the Notes Payable to GST may be satisfied through offsets of amounts due under intercompany services agreements pursuant to which we provide certain corporate services, make available access to group insurance coverage to GST, make advances to third party providers related to payroll and certain benefit plans sponsored by GST, and permit employees of GST to participate in certain of our benefit plans.

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 our senior secured revolving credit facility described in Note 8.

We regularly transact business with GST through the purchase and sale of products. We also provide services for GST including information technology, supply chain, treasury, accounting and tax administration, legal, and human resources under a support services agreement. 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 income tax accounting guidance. This method generally allocates 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.

Amounts included in our financial statements arising from transactions with GST include the following:

	Financial Statement Location	Quarters Ended March 31,
		2013		2012
		(in millions)
Sales to GST	Net sales	$	6.1	$	4.6

Additionally, we had outstanding foreign exchange forward contracts with GST LLC involving the Australian dollar, Canadian dollar, Mexican peso and U.S. dollar with a notional amount of $21.9 million as of March 31, 2013. These related party contracts were eliminated in consolidation prior to the deconsolidation of GST.

Long-Term Debt

Long-Term Debt

8. Long-Term Debt

Convertible Debentures

As of March 31, 2013, we had $172.5 million outstanding in aggregate principal amount of Convertible Debentures, originally issued in October 2005 net of an original issue discount of $61.3 million. The Convertible Debentures bear interest at the annual rate of 3.9375%, with interest due on April 15 and October 15 of each year, and will mature on October 15, 2015, unless they are converted prior to that date. The Convertible Debentures are direct, unsecured and unsubordinated obligations and rank equal in priority with all unsecured and unsubordinated indebtedness and senior in right of payment to all subordinated indebtedness. The Convertible Debentures do not contain any financial covenants.

Holders may convert the Convertible Debentures into cash and shares of our common stock, under certain circumstances described more fully in our most recent Form 10-K. As of April 1, 2013, the Convertible Debentures became convertible by holders of the Convertible Debentures. This conversion right was triggered because the closing price per share of EnPro’s common stock exceeded $43.93, or 130% of the conversion price of $33.79, for at least twenty (20) trading days during the thirty (30) consecutive trading day period ending on March 31, 2013. The Convertible Debentures will be convertible until June 30, 2013, and may be convertible thereafter if one or more of the conversion conditions is satisfied during future measurement periods. Because the Convertible Debentures are currently convertible, the principal balance less the remaining unamortized debt discount was reflected in current maturities of long-term debt as of March 31, 2013.

We used a portion of the net proceeds from the sale of the Convertible 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 stock holders from conversion of the Convertible Debentures and have the effect to us of increasing the conversion price of the Convertible Debentures to $46.78 per share.

The debt discount, $21.7 million as of March 31, 2013, is being amortized through interest expense until the maturity date of October 15, 2015, resulting in an effective interest rate of approximately 9.5%. Interest expense related to the Convertible Debentures for the quarters ended March 31, 2013 and 2012 includes $1.7 million of contractual interest coupon in both periods and $1.8 million and $1.7 million, respectively, of debt discount amortization.

Credit Facility

Our primary U.S. operating subsidiaries, other than GST LLC, have a senior secured revolving credit facility with a maximum availability of $175 million. 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 real property elected to be pledged, 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 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, the Convertible Debentures are paid in full, refinanced on certain terms or defeased, in which case the facility will mature on March 30, 2016. The terms of the facility, including fees and customary covenants and restrictions, are described more fully in our most recent Form 10-K.

The borrowing availability at March 31, 2013, under our senior secured revolving credit facility was $66.3 million after giving consideration to $3.8 million of letters of credit outstanding and $56.0 million of outstanding revolver borrowings.

Derivative Instruments

10. Derivative Instruments

We use derivative financial instruments to manage our exposure to various risks. The use of these financial instruments modifies the exposure with the intent of reducing our risk. We do not use financial instruments for trading purposes, nor do we use leveraged financial instruments. The counterparties to these contractual arrangements are major financial institutions and GST LLC as described in Note 7. We use multiple financial institutions for derivative contracts to minimize the concentration of credit risk. The current accounting rules require derivative instruments, excluding certain contracts that are issued and held by a reporting entity that are both indexed to its own stock and classified in shareholders’ equity, be reported in the Consolidated Balance Sheets at fair value and that changes in a derivative’s fair value be recognized currently in earnings unless specific hedge accounting criteria are met.

We are exposed to foreign currency risks that arise from normal business operations. These risks include the translation of local currency balances on our foreign subsidiaries’ balance sheets, intercompany loans with foreign subsidiaries and transactions denominated in foreign currencies. We strive to control our exposure to these risks through our normal operating activities and, where appropriate, through derivative instruments. We have entered into contracts to hedge forecasted transactions occurring at various dates through December 2014 that are denominated in foreign currencies. The notional amount of foreign exchange contracts hedging foreign currency transactions was $101.1 million and $130.4 million at March 31, 2013 and December 31, 2012, respectively.

Prior to 2013, we applied cash flow hedge accounting to certain of our foreign currency derivatives. We elected to discontinue this accounting treatment in the first quarter of 2013, consequently, all gains and losses that had been deferred in accumulated other comprehensive loss at December 31, 2012 were reclassified to income in the quarter ended March 31, 2013. See Note 13 for additional information. The notional amounts of all of our foreign exchange contracts were recorded at their fair market value as of March 31, 2013 with changes in market value recorded in income. The earnings impact of any foreign exchange contract that is specifically related to the purchase of inventory is recorded in cost of sales and the changes in market value of all other contracts are recorded in selling, general and administrative expense in the Consolidated Statements of Operations. The balances of derivative assets are recorded in other current assets and the balances of derivative liabilities are recorded in accrued expenses in the Consolidated Balance Sheets.

Commitments and Contingencies

15. Commitments and Contingencies

General

A description of 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. Expenses 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 manufacturing 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 or more of our subsidiaries are involved with various remediation activities at 14 sites where the future cost per site for us or our subsidiary is expected to exceed $100 thousand. Investigations have been completed for 11 sites and are in progress at the other three 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.

Our policy is to accrue environmental investigation and remediation costs when it is probable that a liability has been incurred and the amount can be reasonably estimated. The measurement of the liability is based on an evaluation of currently available facts with respect to each individual situation and takes into consideration factors such as existing technology, presently enacted laws and regulations and prior experience in remediation of contaminated sites. Liabilities are established for all sites based on these factors. As assessments and remediation progress at individual sites, these liabilities are reviewed periodically and adjusted to reflect additional technical data and legal information. As of March 31, 2013 and December 31, 2012, we had accrued liabilities of $10.1 million and $11.3 million, respectively, for estimated future expenditures relating to environmental contingencies. These amounts have been recorded on an undiscounted basis in the Consolidated Balance Sheets. 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.

We believe that our accruals for specific environmental liabilities are adequate for those liabilities based on currently available information. Actual costs to be incurred in future periods may vary from estimates because of the inherent uncertainties in evaluating environmental exposures due to unknown and changing conditions, changing government regulations and legal standards regarding liability. 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, some of which are included in the 14 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 the section entitled “Crucible Steel Corporation a/k/a Crucible, Inc.” in this footnote for additional information.

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 our 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, 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.

In conjunction with the closure of a Crucible plant in the early 1980s, Coltec was required to fund a trust for retiree medical benefits for certain employees at the plant. This trust (the “Benefits Trust”) pays for these retiree medical benefits on an ongoing basis. Coltec has no ownership interest in the Benefits Trust, and thus the assets and liabilities of this trust are not included in our Consolidated Balance Sheets. Under the terms of the Benefits Trust agreement, the trustees retained an actuary to assess the adequacy of the assets in the Benefits Trust in 1995 and 2005. A third and final actuarial report will be required in 2015. The actuarial reports in 1995 and 2005 determined that the Benefits Trust has sufficient assets to fund the payment of future benefits. We own a guaranteed investment contract with a current value of $2.6 million, which is being held in a special account in case of a shortfall in the Benefits Trust.

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, in addition to those mentioned previously related to Coltec’s period of ownership of Crucible. Based on Coltec’s prior ownership of Crucible, we may have certain additional 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.

Warranties

We provide warranties on many of our products. The specific terms and conditions of these warranties vary depending on the product and the market in which the product is sold. We record a liability based upon estimates of the costs we may incur under our warranties after a review of historical warranty experience and information about specific warranty claims. Adjustments are made to the liability as claims data and historical experience warrant.

Changes in the carrying amount of the product warranty liability for the three months ended March 31, 2013 and 2012 are as follows:

	2013			2012
	(in millions)
Balance at beginning of year	$	4.1		$	3.5

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 of such plaintiffs. GST LLC and Anchor manufactured and/or sold industrial sealing products that contained encapsulated asbestos fibers. Other subsidiaries of the company 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 neither we nor any of our subsidiaries other than 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.

Subsidiary Chapter 11 Filing and Effect. On the Petition Date, GST LLC, Garrison and Anchor filed voluntary petitions for reorganization under Chapter 11 of the United States Bankruptcy Code in the Bankruptcy Court. The filings were the initial step in a claims resolution process, which is ongoing. See Note 14 for additional information about this process and its impact on us.

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, 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 its quarterly reports for the first and second quarters of 2010.

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 500) have not responded to the questionnaire at all, many others (more than 1,900) reflect claims where the claimants do not have mesothelioma, have acknowledged that they cannot establish exposure to GST products, their claims were dismissed, settled or withdrawn, their claims were duplicates of other filed claims, or were closed or inactive. Still others have responded to the questionnaire but their responses are deficient in some material respect. As a result of this process, less than 3,300 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 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 March 31, 2013, three additional 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 March 31, 2013 we had $141.1 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 $54.0 million since the Petition Date. Of the $141.1 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 $1.1 million (1%) to be of moderate quality because the insurance policies are written with various London market carriers. Of the $141.1 million, $105.1 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 $141.1 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 $141.1 million is in addition to the $0.8 million collected in the first three months of 2013. 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:

2013 – $21.2 million (in the remaining nine months of 2013)

2014 – $21.2 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 and may receive additional payments from insolvent carriers in the future. No anticipated insolvent carrier collections are included in the $141.1 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 March 31, 2013 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. 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 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 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.

Percentage-of-Completion Long-Term Contracts

Percentage-of-Completion Long-Term Contracts

4. Percentage-of-Completion Long-Term Contracts

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 our financial management and reporting systems, we are 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, we recognize revenues using the completed-contract method. We will also continue to use the completed-contract method for engines that were in production at June 30, 2011.

Progress towards completion under POC 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 recognized in the period a loss becomes likely and estimable.

Additional information regarding engine contracts accounted for under the percentage-of-completion method is as follows:

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

On June 5, 2010 (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”). 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 typically would establish a trust to which all asbestos claims would 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.

GST’s financial results were included in our consolidated results through June 4, 2010, the day prior to the Petition Date. However, GAAP requires that 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 and its subsidiaries were with EnPro, 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 on June 4, 2010. 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. This investment is 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.

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 asbestos personal injury claim, i.e., 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 final 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 the 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 Future Claimants’ Representative (the “FCR”) and is unlikely to be approved in its current form. The Claimants’ Committee and FCR have announced their intention to file a competing proposed plan of reorganization.

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 potential proposed plan of reorganization. The estimation trial is scheduled to occur in the third quarter of 2013.

Through March 31, 2013, GST has recorded cumulative reorganization costs, including fees and expenses, in the Chapter 11 case totaling $67.8 million. The total includes $36.5 million for fees and expenses of GST’s counsel and experts; $25.4 million for fees and expenses of counsel and experts for the asbestos claimants’ committee, and $5.9 million for the fees and expenses of the future claims representative and his counsel and experts. GST recorded $10.4 million of those case-related fees and expenses in the first three months of 2013, compared to $7.3 million in the first three months of 2012.

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 in GST.

(A) Liabilities subject to compromise include pre-petition unsecured claims which may be resolved at amounts different from those recorded in the condensed combined balance sheets. Liabilities subject to compromise consist principally of asbestos-related claims. GST has undertaken to project the number and ultimate cost of all present and future bodily injury claims expected to be asserted, based on actuarial principles, and to measure probable and estimable liabilities under generally accepted accounting principles. GST has accrued $466.8 million as of March 31, 2013. The estimate indicated for those asbestos-related claims reflects the point in a wide range of possible outcomes determined based on historical facts and circumstances prior to the Petition Date as our estimate of the cost to resolve asbestos-related personal injury cases and claims against GST as they would have been resolved in the state courts or by settlements over a ten-year period from April 1, 2010 through March 31, 2020. GST adjusts this estimate to reflect payments of previously accrued but unpaid legal fees and to reflect the results of appeals. Otherwise, GST does not expect to adjust the estimate unless developments in the Chapter 11 proceeding provide a reasonable basis for a revised estimate. GST intends to use the claims resolution process in Chapter 11 to determine the validity and ultimate amount of its aggregate liability for asbestos-related claims. Due to the uncertainties of asbestos-related litigation and the Chapter 11 process, GST’s ultimate liability could differ materially from the recorded liability.
