HARSCO CORPORATION

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

1.     Basis of Presentation

Harsco Corporation (the “Company”) has prepared these unaudited condensed consolidated financial statements based on Securities and Exchange Commission rules that permit reduced disclosure for interim periods.  In the opinion of management, all adjustments (all of which are of a normal recurring nature) that are necessary for a fair presentation are reflected in the unaudited condensed consolidated financial statements.  The December 31, 2012 Condensed Consolidated Balance Sheet information contained in this Quarterly Report on Form 10-Q was derived from the 2012 audited consolidated financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States of America (“U.S. GAAP”) for an annual report.  The unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements, including the notes thereto, included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012.

The Company’s management has evaluated all activity of the Company and concluded that subsequent events are properly reflected in the Company’s unaudited condensed consolidated financial statements and notes as required by U.S. GAAP.

Operating results and cash flows for the three months endedMarch 31, 2013 are not indicative of the results that may be expected for the year ending December 31, 2013.

2.     Recently Adopted and Recently Issued Accounting Standards

The following accounting standards have been adopted in 2013:

On January 1, 2013, the Company adopted Financial Accounting Standards Board ("FASB") issued changes related to offsetting assets and liabilities. The changes require additional disclosure regarding the offsetting of assets and liabilities to enable users of financial statements to understand the effect on financial position.  The adoption of these changes did not have a material impact on the Company's consolidated financial statements. The disclosures required by these changes are included in Note 10, "Derivative Instruments, Hedging Activities and Fair Value."

On January 1, 2013, the Company adopted FASB issued changes related to the presentation of reclassification adjustments out of accumulated other comprehensive income.  These changes require additional disclosure related to changes in accumulated other comprehensive income by component and significant items reclassified out of accumulated other comprehensive income. Other than the additional disclosure requirements, the adoption of these changes did not have a material impact on the Company's consolidated financial statements. The disclosures required by these changes are included in Note 13, "Components of Accumulated Other Comprehensive Loss."

The following accounting standard has been issued and becomes effective for the Company at a future date:

In March 2013, the FASB issued changes related to a parent's accounting for the cumulative translation adjustment upon derecognition of certain subsidiaries or groups of assets within a foreign entity or of an investment in a foreign entity. The changes resolve diversity in practice related to these matters. The changes become effective for the Company on January 1, 2014. Management has determined that these changes will not have a material impact on the Company's consolidated financial statements.

Income tax expense from continuing operations increased primarily due to higher income from continuing operations being generated in taxable jurisdictions for the three months endedMarch 31, 2013 compared with the three months endedMarch 31, 2012 offset by the expiration of statutes of limitations for uncertain tax positions in certain foreign jurisdictions and the benefits of retroactive law changes. The effective income tax rate related to continuing operations for the three months ended March 31, 2013 was 34.4% compared with (18.1)% for the three months ended March 31, 2012. The effective income tax rate related to continuing operations changed primarily due to decreased losses being generated in jurisdictions where no tax benefit can be recognized. This was offset by the increase in the expiration of statutes of limitations for uncertain tax positions in certain foreign jurisdictions and the benefits of retroactive law changes in 2013 not present in 2012.

An income tax benefit from an uncertain tax position may be recognized when it is more-likely-than-not that the position will be sustained upon examination, based on technical merits, including resolutions of any related appeals or litigation processes. The unrecognized income tax benefit at March 31, 2013 was $30.1 million including interest and penalties.  Within the next twelve months, it is reasonably possible that up to $3.9 million of unrecognized income tax benefits will be recognized upon settlement of tax examinations and the expiration of various statutes of limitations.

The Company recently has been contacted by the Internal Revenue Service to audit the Company's 2010 U.S. income tax return.  The audit is expected to commence during 2013.

8.  Commitments and Contingencies

Environmental

The Company is involved in a number of environmental remediation investigations and cleanups and, along with other companies, has been identified as a “potentially responsible party” for certain waste disposal sites.  While each of these matters is subject to various uncertainties, it is probable that the Company will agree to make payments toward funding certain of these activities and it is possible that some of these matters will be decided unfavorably to the Company.  The Company has evaluated its potential liability, and its financial exposure is dependent upon such factors as the continuing evolution of environmental laws and regulatory requirements, the availability and application of technology, the allocation of cost among potentially responsible parties, the years of remedial activity required and the remediation methods selected.  The Condensed Consolidated Balance Sheets as of March 31, 2013 and December 31, 2012 include accruals in Other current liabilities of $1.4 million and $1.9 million, respectively, for environmental matters.  The amounts charged against pre-tax income related to environmental matters totaled $0.3 million and $0.2 million for the three months endedMarch 31, 2013 and 2012, respectively.

The Company evaluates its liability for future environmental remediation costs on a quarterly basis. Although actual costs to be incurred at identified sites in future periods may vary from the estimates (given inherent uncertainties in evaluating environmental exposures), the Company does not expect that any costs that are reasonably possible to be incurred by the Company in connection with environmental matters in excess of the amounts accrued would have a material adverse effect on the Company's financial condition, results of operations or cash flows.

Brazilian Tax Disputes

The Company is involved in a number of tax disputes with federal, state and municipal tax authorities in Brazil. These disputes are at various stages of the legal process, including the administrative review phase and the collection action phase, and include assessments of fixed amounts of principal and penalties, plus interest charges that increase at statutorily determined amounts per month and are assessed on the aggregate amount of the principal and penalties. In addition, the losing party at the collection action or court of appeals phase could be subject to a charge to cover statutorily mandated legal fees, which are generally calculated as a percentage of the total assessed amounts due, inclusive of penalty and interest. A large number of the claims relate to value-added ("ICMS"), services and social security ("INSS") tax disputes. The largest proportion of the assessed amounts relate to ICMS claims filed by the State Revenue Authorities from the State of São Paulo, Brazil (the "SPRA"), encompassing the period from January 2002 to May 2005.

In October 2009, the Company received notification of the SPRA’s final administrative decision regarding the levying of ICMS in the State of São Paulo in relation to services provided to a customer in the State between January 2004 and May 2005.  As of March 31, 2013, the principal amount of the tax assessment from the SPRA with regard to this case is approximately $3 million, with penalty, interest and fees assessed to date increasing such amount by an additional $30 million.  Any increase in the aggregate amount since the Company’s Annual Report on Form 10-K for the year ended December 31, 2012 is due to an increase in assessed interest and statutorily mandated legal fees for the year.  All such amounts include the effect of foreign currency translation.

11

Another ICMS tax case involving the SPRA refers to the tax period from January 2002 to December 2003, and is still pending at the administrative phase, where the aggregate amount assessed by the tax authorities in August 2005 was $12 million (the amounts with regard to this claim are valued as of the date of the assessment since it has not yet reached the collection phase), composed of a principal amount of approximately $3 million, with penalty and interest assessed through that date increasing such amount by an additional $9 million.  All such amounts include the effect of foreign currency translation.

The Company continues to believe it is not probable that it will incur a loss for these assessments by the SPRA. The Company also continues to believe that sufficient coverage for these claims exists as a result of the Company’s customer’s indemnification obligations and such customer’s pledge of assets in connection with the October 2009 notice, as required by Brazilian procedure.

The Company intends to continue its practice of vigorously defending itself against these tax claims under various alternatives, including judicial appeal. The Company will continue to evaluate its potential liability with regard to these claims on a quarterly basis; however, it is not possible to predict the ultimate outcome of these tax-related disputes in Brazil. No loss provision has been recorded in the Company's consolidated financial statements because the loss contingency is not deemed probable, and the Company does not expect that any costs that are reasonably possible to be incurred by the Company in connection with Brazilian tax disputes would have a material adverse effect on the Company's financial condition, results of operations or cash flows.

Customer Disputes

The Company, through its Harsco Metals & Minerals Segment, provides services to various subsidiaries and affiliates of ArcelorMittal (collectively, "ArcelorMittal") on a number of sites worldwide through long-term service contracts. Currently, ArcelorMittal and the Company are involved in several commercial disputes, a few of which have resulted in legal action. Both the Company and ArcelorMittal are working to resolve these matters. Although results of operations and cash flows for a given period could be adversely affected by a negative outcome in these or other lawsuits, claims and proceedings, management believes that the ultimate outcome of these matters will not have a material adverse effect on the Company's financial condition, results of operations or cash flows.

Other

In the United States, the Company has been named as one of many defendants (approximately 90 or more in most cases) in legal actions alleging personal injury from exposure to airborne asbestos over the past several decades.  In their suits, the plaintiffs have named as defendants, among others, many manufacturers, distributors and installers of numerous types of equipment or products that allegedly contained asbestos.

The Company believes that the claims against it are without merit.  The Company has never been a producer, manufacturer or processor of asbestos fibers.  Any component within a Company product that may have contained asbestos would have been purchased from a supplier.  Based on scientific and medical evidence, the Company believes that any asbestos exposure arising from normal use of any Company product never presented any harmful levels of airborne asbestos exposure, and, moreover, the type of asbestos contained in any component that was used in those products was protectively encapsulated in other materials and is not associated with the types of injuries alleged in the pending suits.  Finally, in most of the depositions taken of plaintiffs to date in the litigation against the Company, plaintiffs have failed to specifically identify any Company products as the source of their asbestos exposure.

The majority of the asbestos complaints pending against the Company have been filed in New York.  Almost all of the New York complaints contain a standard claim for damages of $20 million or $25 million against the approximately 90 defendants, regardless of the individual plaintiff’s alleged medical condition, and without specifically identifying any Company product as the source of plaintiff’s asbestos exposure.

As of March 31, 2013, there are 18,090 pending asbestos personal injury claims filed against the Company.  Of these cases, 17,600 are pending in the New York Supreme Court for New York County in New York State.  The other claims, totaling 490, are filed in various counties in a number of state courts, and in certain Federal District Courts (including New York), and those complaints generally assert lesser amounts of damages than the New York State court cases or do not state any amount claimed.

As of March 31, 2013, the Company has obtained dismissal by stipulation, or summary judgment prior to trial, in 26,715 cases.

In view of the persistence of asbestos litigation nationwide, the Company expects to continue to receive additional claims.  However, there have been developments during the past several years, both by certain state legislatures and by certain state courts, which could favorably affect the Company’s ability to defend these asbestos claims in those jurisdictions.  These developments include procedural changes, docketing changes, proof of damage requirements and other changes that require plaintiffs to follow specific procedures in bringing their claims and to show proof of damages before they can proceed with their claim.  An example is the action taken by the New York Supreme Court (a trial court), which is responsible for managing

12

all asbestos cases pending within New York County in the State of New York.  This Court issued an order in December 2002 that created a Deferred or Inactive Docket for all pending and future asbestos claims filed by plaintiffs who cannot demonstrate that they have a malignant condition or discernible physical impairment, and an Active or In Extremis Docket for plaintiffs who are able to show such medical condition.  As a result of this order, the majority of the asbestos cases filed against the Company in New York County have been moved to the Inactive Docket until such time as the plaintiffs can show that they have incurred a physical impairment.  As of March 31, 2013, the Company has been listed as a defendant in 477 Active or In Extremis asbestos cases in New York County.  The Court’s Order has been challenged by some plaintiffs.

Except with regard to the legal costs in a few limited, exceptional cases, the Company’s insurance carrier has paid all legal and settlement costs and expenses to date related to the Company’s U.S. asbestos cases.  The Company has liability insurance coverage under various primary and excess policies that the Company believes will be available, if necessary, to substantially cover any liability that might ultimately be incurred on these claims.

The Company intends to continue its practice of vigorously defending these claims and cases. It is not possible to predict the ultimate outcome of asbestos-related lawsuits, claims and proceedings due to the unpredictable nature of personal injury litigation, and no loss provision has been recorded in the Company's consolidated financial statements because a loss contingency is not deemed probable or estimable. Despite this uncertainty, and although results of operations and cash flows for a given period could be adversely affected by asbestos-related lawsuits, claims and proceedings, the Company does not expect that any costs that are reasonably possible to be incurred by the Company in connection with asbestos litigation would have a material adverse effect on the Company's financial condition, results of operations or cash flows.

The Company is subject to various other claims and legal proceedings covering a wide range of matters that arose in the ordinary course of business.  In the opinion of management, all such matters are adequately covered by insurance or by established reserves, and, if not so covered, are without merit or are of such kind, or involve such amounts, as would not have a material adverse effect on the financial position, results of operations or cash flows of the Company.

Insurance liabilities are recorded when it is probable that a liability has been incurred for a particular event and the amount of loss associated with the event can be reasonably estimated.  Insurance reserves have been estimated based primarily upon actuarial calculations and reflect the undiscounted estimated liabilities for ultimate losses, including claims incurred but not reported.  Inherent in these estimates are assumptions that are based on the Company’s history of claims and losses, a detailed analysis of existing claims with respect to potential value, and current legal and legislative trends.  If actual claims differ from those projected by management, changes (either increases or decreases) to insurance reserves may be required and would be recorded through income in the period the change was determined.  When a recognized liability is covered by third-party insurance, the Company records an insurance claim receivable to reflect the covered liability.  Insurance claim receivables are included in Other receivables on the Company’s Condensed Consolidated Balance Sheets.  See Note 1, “Summary of Significant Accounting Policies,” to the consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012 for additional information on Accrued Insurance and Loss Reserves.

10.  Derivative Instruments, Hedging Activities and Fair Value

Derivative Instruments and Hedging Activities

The Company uses derivative instruments, including foreign currency forward exchange contracts, commodity contracts and cross-currency interest rate swaps, to manage certain foreign currency, commodity price and interest rate exposures.  Derivative instruments are viewed as risk management tools by the Company and are not used for trading or speculative purposes.

All derivative instruments are recorded on the Condensed Consolidated Balance Sheets at fair value.  Changes in the fair value of derivatives used to hedge foreign currency denominated balance sheet items are reported directly in earnings along with offsetting transaction gains and losses on the items being hedged.  Derivatives used to hedge forecasted cash flows associated with foreign currency commitments or forecasted commodity purchases may be accounted for as cash flow hedges, as deemed appropriate and if the criteria for hedge accounting are met.  Gains and losses on derivatives designated as cash flow hedges are deferred as a separate component of equity and reclassified to earnings in a manner that matches the timing of the earnings impact of the hedged transactions.  Generally, at March 31, 2013, these deferred gains and losses are reclassified to earnings over 10 to 15 years from the balance sheet date.  The ineffective portion of all hedges, if any, is recognized currently in earnings.

The fair values of outstanding derivative contracts recorded as assets and liabilities on the Condensed Consolidated Balance Sheets at March 31, 2013 and December 31, 2012 were as follows:

	Asset Derivatives (a)			Liability Derivatives (a)

(a) All of the Company's derivatives are recorded in the Condensed Consolidated Balance Sheets as gross amounts and not offset. All of the Company's cross currency interest rate swaps and certain foreign currency forward exchange contracts are transacted under International Swaps and Derivatives Association ("ISDA") documentation. Each ISDA master agreement permits the net settlement of amounts owed in the event of default. The Company's derivative assets and liabilities subject to enforceable master netting arrangements total $0.2 million at March 31, 2013 and $0.1 million at December 31, 2012.

(a)  These gains (losses) offset amounts recognized in cost of services and products sold principally as a result of intercompany or third party foreign currency exposures.

Foreign Currency Forward Exchange Contracts

The Company conducts business in multiple currencies and, accordingly, is subject to the inherent risks associated with foreign exchange rate movements.  The financial position and results of operations of substantially all of the Company’s foreign subsidiaries are measured using the local currency as the functional currency.  Foreign currency-denominated assets and liabilities are translated into U.S. dollars at the exchange rates existing at the respective balance sheet dates. Income and expense items are translated at the average exchange rates during the respective periods.  The aggregate effects of translating the balance sheets of these subsidiaries are deferred and recorded in Accumulated other comprehensive loss, which is a separate component of equity.

The Company uses derivative instruments to hedge cash flows related to foreign currency fluctuations.  Foreign currency forward exchange contracts outstanding are part of a worldwide program to minimize foreign currency exchange operating income and balance sheet exposure by offsetting foreign currency exposures of certain future payments between the Company and its various subsidiaries, suppliers or customers.  These unsecured contracts are with major financial institutions.  The Company may be exposed to credit loss in the event of non-performance by the contract counterparties.  The Company evaluates the creditworthiness of the counterparties and does not expect default by them.  Foreign currency forward exchange contracts are used to hedge commitments, such as foreign currency debt, firm purchase commitments and foreign currency cash flows for certain export sales transactions.

15

The following tables summarize, by major currency, the contractual amounts of the Company’s foreign currency forward exchange contracts in U.S. dollars at March 31, 2013 and December 31, 2012.  The “Buy” amounts represent the U.S. dollar equivalent of commitments to purchase foreign currencies, and the “Sell” amounts represent the U.S. dollar equivalent of commitments to sell foreign currencies.  The recognized gains and losses offset amounts recognized in cost of services and products sold principally as a result of intercompany or third party foreign currency exposures.

In addition to foreign currency forward exchange contracts, the Company designates certain loans as hedges of net investments in international subsidiaries.  The Company recorded pre-tax net gains of $1.7 million and pre-tax net losses $6.7 million during the three months endedMarch 31, 2013 and 2012, respectively, into Accumulated other comprehensive loss.

Cross-Currency Interest Rate Swaps

The Company uses cross-currency interest rate swaps in conjunction with certain debt issuances in order to secure a fixed local currency interest rate.  Under these cross-currency interest rate swaps, the Company receives interest based on a fixed or floating U.S. dollar rate and pays interest on a fixed local currency rate based on the contractual amounts in dollars and the local currency, respectively.  The cross-currency interest rate swaps are recorded on the Condensed Consolidated Balance Sheets at fair value, with changes in value attributed to the effect of the swaps’ interest spread recorded in Accumulated other comprehensive loss.  Changes in value attributed to the effect of foreign currency fluctuations are recorded in the statements of operations and offset currency fluctuation effects on the debt principal. The following table indicates the contractual amounts of the Company's cross-currency interest rate swaps at March 31, 2013:

			Interest Rates
(In millions)	Contractual Amount		Receive	Pay
Maturing 2018	$	250.0	Fixed U.S. dollar rate	Fixed euro rate
Maturing 2020	220.0		Fixed U.S. dollar rate	Fixed British pound sterling rate
Maturing 2013 through 2017	10.8		Floating U.S. dollar rate	Fixed rupee rate

Fair Value of Derivative Assets and Liabilities and Other Financial Instruments

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (an exit price).  The Company utilizes market data or assumptions that the Company believes market participants would use in valuing the asset or liability, including assumptions about risk and the risks inherent in the inputs to the valuation technique.

The fair value hierarchy distinguishes between (1) market participant assumptions developed based on market data obtained from independent sources (observable inputs), and (2) an entity’s own assumptions about market participant assumptions based on the best information available in the circumstances (unobservable inputs).  The fair value hierarchy consists of three broad levels, which gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3).  The three levels of the fair value hierarchy are described below:

• Level 1—Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities.

• Level 2—Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly, including quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; inputs other than quoted prices that are observable for the asset or liability (e.g., interest rates); and inputs that are derived principally from or corroborated by observable market data by correlation or other means.

• Level 3—Inputs that are both significant to the fair value measurement and unobservable. 

In instances in which multiple levels of inputs are used to measure fair value, hierarchy classification is based on the lowest level input that is significant to the fair value measurement in its entirety.  The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the asset or liability.

The following table indicates the fair value hierarchy of the financial instruments of the Company at March 31, 2013 and December 31, 2012:

Level 2 Fair Value Measurements

(In thousands)	March 31 2013		December 31 2012
Assets
Foreign currency forward exchange contracts	$	2,200	$	853
Cross-currency interest rate swaps	47,947		39,058
Liabilities
Foreign currency forward exchange contracts	3,671		1,775
Cross-currency interest rate swaps	199		14,346

The Company primarily applies the market approach for recurring fair value measurements and endeavors to utilize the best available information.  Accordingly, the Company utilizes valuation techniques that maximize the use of observable inputs, such as forward rates, interest rates, the Company’s credit risk and counterparties’ credit risks, and which minimize the use of unobservable inputs.  The Company is able to classify fair value balances based on the ability to observe those inputs.  Commodity derivatives, foreign currency forward exchange contracts and cross-currency interest rate swaps are classified as Level 2 fair value based upon pricing models using market-based inputs.  Model inputs can be verified, and valuation techniques do not involve significant management judgment.

The carrying amounts of cash and cash equivalents, accounts receivable, accounts payable, accrued liabilities and short-term borrowings approximate fair value due to the short-term maturities of these assets and liabilities.  At March 31, 2013 and December 31, 2012, the total fair value of long-term debt, including current maturities, was $1.1 billion and $1.0 billion, respectively, compared to a carrying value of $1.0 billion in both periods.  Fair values for debt are based on quoted market prices (Level 1) for the same or similar issues, or on the current rates offered to the Company for debt of the same remaining maturities.

14.   Restructuring Programs

In recent years, the Company instituted restructuring programs to balance short-term profitability goals with long-term strategies to establish platforms upon which the affected businesses can grow with reduced fixed investment and generate annual operating expense savings.  The restructuring programs have been instituted in response to the continuing impact of global financial and economic uncertainty on the Company’s end markets, particularly in the Company’s Harsco Infrastructure Segment. Restructuring costs incurred in these programs were recorded in the Other (income) expenses line of the Condensed Consolidated Statements of Operations. The timing of associated cash payments is dependent on the type of restructuring cost and can extend over a multi-year period.

2011/2012 Restructuring Program

Under the 2011/2012 Restructuring Program, the Company optimized rental assets and sale inventories by removing non-core assets under an expanded product rationalization and branch structure reduction program undertaken in its Harsco Infrastructure Segment and optimized office structures and reduced global workforce in the Harsco Infrastructure and Harsco Metals & Minerals Segments. Benefits under this program, in the form of reduced costs when compared to 2011, are expected to be approximately $63 million for the full year of 2013. This represents an incremental $8 million in benefits under this program when compared with the benefits realized in 2012. The restructuring accrual for the 2011/2012 Restructuring Program at March 31, 2013 and the activity for the three months then ended are as follows:

(In thousands)	Accrual December 31 2012		Non-Cash Charges / Other Adjustments			Cash Expenditures			Foreign Currency Translation			Remaining Accrual March 31 2013
Harsco Infrastructure Segment
Employee termination benefit costs	$	6,999	$	(94	)	$	(3,300	)	$	(240	)	$	3,365
Cost to exit activities	9,000		(304		)	(1,629		)	(130		)	6,937

Total	$	23,005	$	(403	)	$	(7,651	)	$	(527	)	$	14,424

(a)    The table does not include $0.3 million of proceeds from asset sales under the 2011/2012 Restructuring Program for this Segment as this item did not impact the restructuring accrual during the three months endedMarch 31, 2013.

Cash expenditures related to the remaining employee termination benefit costs accrual at March 31, 2013 are expected to be paid principally throughout the remainder of 2013 with approximately $6.5 million of exit activity costs for lease terminations expected to be paid over the remaining life of the leases.

Fourth Quarter 2010 Harsco Infrastructure Program

Under the Fourth Quarter 2010 Harsco Infrastructure Program, the Harsco Infrastructure Segment reduced its branch structure; consolidated and/or closed administrative office locations; reduced its global workforce; and rationalized its product lines. The restructuring accrual for the Fourth Quarter 2010 Harsco Infrastructure Program at March 31, 2013 and the activity for the three months then ended are as follows:

(In thousands)	Accrual December 31 2012		Non-cash Charges / Other Adjustments		Cash Expenditures			Foreign Currency Translation			Remaining Accrual March 31 2013
Harsco Infrastructure Segment
Cost to exit activities	$	6,791	$	96	$	(180	)	$	(1	)	$	6,706

Approximately $6.2 million of the March 31, 2013 balance relates to payment of multiemployer pension plan withdrawal liabilities and is expected to be paid through 2023 under contractual payment terms with the related plan administrators.  The remaining balance primarily relates to costs for lease terminations that are expected to be paid over the remaining life of the leases.

Operating income from continuing operations for the first quarter of 2013 was $25.8 million compared with an operating loss from continuing operations of $12.7 million in the first quarter of 2012.  The change primarily reflects pre-tax 2011/2012 Restructuring Program costs of $35.4 million and former CEO separation pretax costs of $4.1 million that were incurred in the first quarter of 2012 and not repeated in the first quarter of 2013; ongoing realization of benefits from prior cost-reduction actions; and improved performance in the Harsco Industrial Segment. These improvements were partially offset by an unfavorable mix of equipment deliveries in the Harsco Rail Segment compared with the prior-year quarter, as well as lower volumes in the Harsco Metals & Minerals Segment.

Diluted earnings per share from continuing operations for the first quarter of 2013 were $0.09 compared with a diluted loss per share of $0.36 for the first quarter of 2012.

22

Under the 2011/2012 Restructuring Program, the Company optimized rental assets and sale inventories by removing non-core assets under an expanded product rationalization and branch structure reduction program undertaken in its Harsco Infrastructure Segment; optimized office structures and reduced the global workforce in the Harsco Infrastructure and Harsco Metals & Minerals Segments. Benefits under this program, in the form of reduced costs when compared to 2011, are expected to be approximately $63 million for the full year of 2013. This represents an incremental $8 million in benefits under this program when compared with the benefits realized in 2012.

The Company continues to have sufficient available liquidity and has been able to obtain all necessary financing. The Company currently expects operational and business needs to be met by cash from operations supplemented with borrowings from time to time due to historical patterns of seasonal cash flow and for the funding of various projects. See Liquidity and Capital Resources below for further discussion on liquidity, capital resources and cash flows.

Impact of foreign currency translation	(9.4		)
Revenues — 2013	$	337.3

Significant Impacts on Operating Income:

• Lower global steel production in the steel mills services business.  Overall, steel production by customers under services contracts was down 5% in the first quarter of 2013 compared to the same period in 2012.

• Lower demand and pricing for scrap in North America.

• These impacts were partially offset by overall cost reductions from the 2011/2012 Restructuring Program.

• Foreign currency translation did not significantly impact operating income in the first quarter quarter of 2013.

Net decreased volume	(8.2		)
Impact of foreign currency translation	(2.4		)
Revenues — 2013	$	216.1

Significant Effects on Operating Income:

• Operating income was positively affected in the first three months of 2013 by continued realization of expected cost savings resulting from restructuring initiatives implemented in prior years and the impact of exiting unprofitable countries.

• Pre-tax restructuring program costs totaling $35.6 million that were incurred in the first quarter of 2012 for the 2011/2012 Restructuring Program and were not repeated in the first quarter of 2013.

• Improved operating performance in North America and the Middle East was offset in certain parts of Europe due to poor weather conditions and the delay of industrial services.

• Foreign currency translation in the first three months of 2013 increased operating income for this Segment by $0.8 million compared with the same period in the prior year.

Harsco Rail Segment:

	Three Months Ended
Significant Effects on Revenues (In millions)	March 31, 2013
Revenues — 2012	$	68.0
Net increased volume	3.9
Impact of foreign currency translation	(0.3		)
Revenues — 2013	$	71.6

Significant Impacts on Operating Income:

• This Segment's operating income for the first three months of 2013 was lower than the first three months of 2012 due principally to the timing and mix of equipment deliveries in China as part of its large order with the Ministry of Railways compared with the prior-year quarter.

• Operating income was also negatively impacted in the first three months of 2013 by lower service revenues, partially offset by strong parts sales.

• Foreign currency translation in the first three months of 2013 decreased operating income for this segment by $0.6 million compared with the same period in the prior year.

Harsco Industrial Segment:

	Three Months Ended
Significant Effects on Revenues (In millions)	March 31, 2013
Revenues — 2012	$	86.4
Net increased volume	4.0
Revenues — 2013	$	90.4

Significant Effects on Operating Income:

• This Segment's operating income for the first three months of 2013 was higher than the first three months of 2012 due principally to favorable overall product mix, as well as improved demand for industrial boilers, in the heat transfer products business, and air-cooled heat exchangers verse the prior year quarter.

Outlook, Trends and Strategies

In addition to items noted in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012, the following significant items, risks, trends and strategies are expected to affect the Company for the remainder of 2013 and beyond:

• Management will continue to be very selective and disciplined in allocating capital, choosing projects with the highest EVA potential and return on capital employed. The Company expects capital expenditures in 2013 to be in line with capital expenditures in 2012.

• The Company had a balance sheet debt to capital ratio of 54.0% at March 31, 2013. The ratio has increased in recent years primarily due to decreased equity resulting from the $265.0 million goodwill impairment charge recorded for the Harsco Infrastructure Segment in 2012; the restructuring charges incurred in 2012 and 2011; and pension liability adjustments in 2012 and 2011, including the deferred tax valuation allowance recorded related to U.K. pension liabilities in 2011. Although the debt to capital ratio increased slightly in the first quarter of 2013 due to the timing of earnings and cash flows, the Company expects this ratio to gradually improve during the remainder of 2013 and beyond based on improved results of operations and cash flows.

• The Company expects its effective income tax rate to approximate 30 percent for the full year 2013. This modest increase from historical levels is due to losses from operations in certain jurisdictions where tax benefits will not be able to be recognized, as well as the geographic mix of income. Going forward, there may be some variability in the reported tax rate from quarter-to-quarter depending on the actual geographic mix of earnings.

Harsco Metals & Minerals Segment:

• This Segment continues to be impacted by the overall weak economic climate in the global steel industry, particularly in developed markets. Total customer steel production has declined year-over-year in recent quarters, but with modest upturn in the first quarter of 2013 compared to the fourth quarter of 2012. Market forecasts are mixed for the remainder of 2013.

24

• The Company will continue its focus on ensuring forecasted profits for renewed contracts meet certain pre-established requirements.  In addition, the Company will focus on winning contracts in emerging markets where steel production is increasing and where the customers value the Company's environmental solutions. Given this strategy, the possibility exists that additional contracts may not be renewed, resulting in exit costs during the period in which such decisions are finalized.

• Longer term, an example of the execution of the Company's strategy is the 25-year environmental solutions contract for on-site metal recovery in China that was awarded in July 2011 to the Company's venture with Taiyuan Iron & Steel (Group) Co, Ltd. ("TISCO"). This contract will effectively address the environmentally-beneficial processing and metal recovery of TISCO's stainless and carbon steel slag production by-products across a range of potential commercial applications.  The Company anticipates that the venture has the potential to generate initial year new revenues of approximately $18 million as operations ramp-up in the first half of 2013; approximately $30 million in subsequent years; and ramping up to a projected run rate of approximately $50 million to $60 million per year when fully operational.  The Company and TISCO share a 60%-40% relationship in the partnership, respectively, and the Company consolidates the financial statements of the venture.

• Another example of the Company's longer-term strategy is the June 2012 announcement of a new 20-year environmental services contract for the environmentally-beneficial handling and processing of steelmaking by-products with Tangshan Iron & Steel, the flagship site of China's largest steelmaker, Hebei Iron & Steel (HBIS) Group, the second largest producer of steel in the world. This contract significantly expands the Company's existing resource recovery services at the Tangshan works under a new strategic venture relationship led by the Company that focuses directly on improving the surrounding environment from steelmaking operations.

• One of the Company's large steel mill customers in Europe has filed for receivership. The Company has less than $10 million of receivables with this customer and believes that these amounts are collectible. Should there be an adverse change in the Company's view on collectability, however, there could be a charge against income in future periods.

Harsco Infrastructure Segment:

• The Company expects the Harsco Infrastructure Segment to realize a steady year-over-year improvement in operating performance as it globally focuses on driving sales performance and continuing activities to improve efficiencies in yard, asset and project management. This Segment is expected to continue to realize the benefits from the successful implementation of the Fourth Quarter 2010 Harsco Infrastructure Restructuring Program and the 2011/2012 Restructuring Program.

• Uncertainties remain in key end markets, particularly in the challenged economies in Europe and, to a lesser extent, impacts from low commodity prices on activities in locations such as Australia. The Company does not expect overall material improvement in this Segment's end markets in 2013, although some regions are expected to show improvement.

Harsco Rail Segment:

• The short-term outlook for this business is unfavorably impacted by the timing of shipments for its large China Ministry of Railways rail grinder orders, which were mostly completed during the first quarter of 2013. Compared with 2012, revenues for this Segment are expected to decline approximately $50 million in 2013 due to the completion of the order. The success in China has been leveraged to secure several new orders in other geographies, as well as with multiple metro systems in China; however, none of the individual orders are as large as the Ministry of Railways nor will the new orders have a significant impact on 2013 results.

• The longer-term outlook for this Segment continues to be favorable. The global demand for railway maintenance-of-way equipment, parts, and services continues to be strong, giving positive indication of further opportunities for this Segment.

• Consistent with its growth strategy, the Harsco Rail Segment recently announced new orders in the track maintenance group, including four new equipment orders from China, a rail grinder equipment order for delivery in late 2014 with an interim services agreement in Italy, and a Track Renewal Train equipment order for delivery in early 2014 in India.

Harsco Industrial Segment:

• The Harsco Industrial Segment is expecting another year of consistent performance for revenue and operating income in 2013, and will continue to focus on product innovation and development to drive strategic growth in its businesses.

• Overall, the Segment's markets are stable with demand in the air-cooled heat exchangers business remaining strong, and slight improvement is expected in the industrial boilers market for the heat transfer products business as well as industrial grating.

(a) Other includes employee termination benefit costs, impaired asset write-downs, and costs to exit activities that are not directly related to the restructuring programs detailed in Note 14, "Restructuring Programs," in Part I, Item 1, Financial Statements.

Interest Expense

Interest expense decreased $1.1 million from the first quarter of 2012.  The change is primarily due to the financing costs associated with the revolving credit facility, which were recognized when this facility was renewed in March 2012, and fluctuations in foreign currency exchange rates, partially offset by higher interest on outstanding credit facility and commercial paper balances.

Income Tax Expense

Income tax expense from continuing operations increased primarily due to higher income from continuing operations being generated in taxable jurisdictions for the three months endedMarch 31, 2013 compared with the three months endedMarch 31, 2012, offset by the expiration of statutes of limitations for uncertain tax positions in certain foreign jurisdictions and the benefits of retroactive law changes. The effective income tax rate related to continuing operations for the three months endedMarch 31, 2013 was 34.4% compared with (18.1)% for the three months endedMarch 31, 2012. The effective income tax rate changed primarily due to decreased losses being generated in jurisdictions where no tax benefit can be recognized, offset by the increase in the expiration of statutes of limitations for uncertain tax positions in certain foreign jurisdictions and the benefits of retroactive law changes in 2013 not present in 2012.

Income from continuing operations of $9.5 million in the first quarter of 2013 was $38.6 millionhigher than the $29.2 million loss from continuing operations for the same period of 2012. The increase primarily reflects the 2011/2012 Restructuring Program and former CEO separation costs that were not repeated in 2013; ongoing realization of benefits from prior cost-reduction actions; and improved performance in the Harsco Industrial Segment. These gains were partially offset by an unfavorable mix of equipment deliveries in the Harsco Rail Segment compared with the prior-year quarter, as well as lower volumes in the Harsco Metals & Minerals Segment.

Liquidity and Capital Resources

Overview

The Company continues to have sufficient available liquidity and has been able to obtain all necessary financing.  The Company currently expects operational and business needs to be met with cash from operations supplemented with borrowings from time to time due to historical patterns of seasonal cash flow and for the funding of various projects.

The Company continues to implement and perform capital efficiency initiatives to enhance liquidity.  These initiatives have included: prudent allocation of capital spending to projects where the highest returns can be achieved while redeploying existing capital investments; optimization of worldwide cash positions; reductions in discretionary spending; and frequent evaluation of customer and business-partner credit risk. 

During the first three months of 2013, the Company’s operations provided $3.4 million in operating cash flow, an increase from the $1.4 million used in the first three months of 2012.  Approximately $8 million of operating cash was disbursed in the first three months of 2013 for restructuring costs associated with the Fourth Quarter 2010 Harsco Infrastructure Program and the 2011/2012 Restructuring Program compared to approximately $29 million of operating cash disbursed in the first three months of 2012.  In the first three months of 2013, the Company invested $53.7 million in capital expenditures, mostly for the Harsco Metals & Minerals Segment (approximately 49% of the total capital expenditures were for revenue-growth projects), compared with $52.8 million invested in the first three months of 2012.  The Company paid $16.5 million in stockholder dividends in the first three months of both 2013 and 2012.

The Company’s net cash borrowings increased by $52.7 million in the first three months of 2013, primarily to fund capital expenditures, principally in the Harsco Metals & Minerals Segment.  The Company’s debt to total capital ratio increased to 54.0% at March 31, 2013 from 52.9% at December 31, 2012.  The increase at March 31, 2013 is primarily due to the increased net cash borrowings for the first three months of 2013.

The Company plans to sustain its balanced portfolio through its strategy of redeploying discretionary cash for disciplined organic growth and international or market-segment diversification; for potential strategic ventures, alliances and partnerships; for growth in long-term, high-return service contracts for the Harsco Metals & Minerals Segment, principally in targeted growth markets or for customer diversification; and for strategic investments or possible acquisitions in the Harsco Rail Segment and Harsco Industrial Segment.  The Company also foresees continuing its long and consistent history of paying dividends to stockholders.

The Company continues its focus on improving working capital efficiency.  The Company’s Continuous Improvement initiatives are being used to further improve the effective and efficient use of working capital, particularly accounts receivable and inventories.

The Company also generated $10.6 million in cash from asset sales in the first three months of 2013. The Company plans to continue to supplement cash from operations with future asset sales.

Sources and Uses of Cash

The Company’s principal sources of liquidity are cash from operations and borrowings under its various credit agreements, augmented periodically by cash proceeds from asset sales.  The primary drivers of the Company’s cash flow from operations are the Company’s revenues and income.  The Company’s long-term Harsco Metals & Minerals Segment contracts, in addition to the backlog of certain equipment orders within the Harsco Rail Segment, provide predictable cash flows for the near-term years.  Cash returns on capital investments made in prior years, for which limited cash is currently required, are a significant source of cash from operations.  Depreciation expense related to these investments is a non-cash charge. 

Major uses of operating cash flows and borrowed funds include: capital investments, principally in the Harsco Metals & Minerals Segment; payroll costs and related benefits; dividend payments; pension funding payments; inventory purchases for the Harsco Rail and Harsco Industrial Segments; income tax payments; debt principal and interest payments; insurance premiums and payments of self-insured casualty losses; and machinery, equipment, automobile and facility lease payments. Additionally, in 2012, there were significant payments under the 2011/2012 Restructuring Program.  Cash may also be used for targeted strategic acquisitions as appropriate opportunities arise.

28

Resources available for cash requirements

The Company meets its ongoing cash requirements for operations and growth initiatives by utilizing cash from operations and by borrowings under the Company's various credit agreements augmented periodically by cash proceeds from asset sales.  Public markets are accessed through discrete-term note issuance to investors.  The Company has various bank credit facilities that are available throughout the world.  The Company expects to utilize public debt markets, bank credit facilities and cash from operations to meet its cash requirements in the future.

The following table illustrates the amounts outstanding under credit facilities and commercial paper programs and available credit at March 31, 2013:

	March 31, 2013
(In millions)	Facility Limit		Outstanding Balance		Available Credit
U.S. commercial paper program	$	550.0	$	25.0	$	525.0
Multi-year revolving credit agreement (a)	525.0		104.0		421.0
Totals	$	1,075.0	$	129.0	$	946.0	(b)

(a)   U.S.-based program.

(b)   Although the Company has significant available credit, for practical purposes, the Company limits aggregate commercial paper and credit facility borrowings at any one-time to a maximum of $525 million (the amount of the multi-year revolving credit agreement).

At March 31, 2013 and December 31, 2012, the Company had $129.0 million and $89.5 million, respectively, of commercial paper and credit facility borrowings outstanding. At both March 31, 2013 and December 31, 2012, all such balances were classified as long-term borrowings in the Condensed Consolidated Balance Sheets. Classification of such balances is based on the Company's ability and intent to repay such amounts over the subsequent twelve months, as well as the Company's intent and ability to borrow for a period longer than a year.To the extent the Company expects to repay any amounts within the subsequent twelve months, the amounts would be classified as short-term borrowings.

At March 31, 2013, the Company's 5.125% notes due September 15, 2013, $150 million aggregate principal, are classified as Long-term debt on the Condensed Consolidated Balance Sheet based on the Company's intent and ability to refinance this debt using borrowings under the Company's multi-year revolving credit facility.

Credit Ratings and Outlook

The following table summarizes the Company’s current debt ratings:

Rating Agency	Long-term Notes	U.S.-Based Commercial Paper	Watch / Outlook
Standard & Poor’s (S&P)	BBB-	A-3	Negative Outlook
Moody’s	Ba1	Not Prime	Stable Outlook
Fitch	BBB	F3	Negative Outlook

In March 2013, S&P downgraded the Company's long-term and short-term ratings to BBB- and A-3, respectively, while maintaining a negative outlook. Moody's downgraded the Company's long-term and short-term ratings to Ba1 and Not Prime, respectively, while upgrading to a stable outlook. The impact of these rating agency actions was an increase to the Company's short-term borrowing costs and reduced access to certain short-term credit markets. Future downgrades to the Company’s credit ratings may increase borrowing costs to the Company, while an improvement in the Company’s credit ratings may decrease borrowing costs to the Company.  However, future downgrades in the Company’s credit ratings will not reduce access to the Company's $525 million multi-year revolving credit facility.

Working Capital Position

Changes in the Company’s working capital are reflected in the following table:

(Dollars in millions)	March 31 2013		December 31 2012		Increase (Decrease)
Current Assets
Cash and cash equivalents	$	92.9	$	95.3	$	(2.3	)
Trade accounts receivable, net	622.2		600.3		21.9
Other receivables	39.7		39.8		(0.2		)
Inventories	244.5		236.5		8.0
Other current assets	96.6		94.6		2.1
Total current assets	1,095.9		1,066.4		29.5
Current Liabilities
Notes payable and current maturities	16.6		11.8		4.7
Accounts payable	231.6		221.5		10.1
Accrued compensation	74.1		94.4		(20.3		)
Income taxes payable	8.9		10.1		(1.2		)
Other current liabilities	286.9		299.8		(12.9		)
Total current liabilities	618.0		637.6		(19.6		)
Working Capital	$	477.9	$	428.9	$	49.0
Current Ratio (a)	1.8		1.7

(a)          Calculated as Total current assets/Total current liabilities 

Working capital increased $49.0 million in the first three months of 2013 due principally to the following factors:

• Trade accounts receivable, net increased $21.9 million, primarily due to timing of invoicing and collections primarily in the Harsco Metals & Minerals and Harsco Rail Segments;

• Accrued compensation decreased by $20.3 million primarily due to the payment of incentive compensation from 2012; and

• Other current liabilities decreased $12.9 million primarily due to a decrease in customer advances related to the delivery of certain machines in the Harsco Rail Segment.

These working capital increases were partially offset by the following:

• Accounts payable increased by $10.1 million due to the timing of payments.

Certainty of Cash Flows

The certainty of the Company’s future cash flows is underpinned by the long-term nature of the Company’s metals services contracts and overall discretionary cash flows (operating cash flows plus cash from asset sales in excess of the amounts necessary for capital expenditures to maintain current revenue levels) generated by the Company.  Historically, the Company has utilized these discretionary cash flows for growth-related capital expenditures, strategic acquisitions, debt repayment and dividend payments.

The types of products and services that the Company provides are not subject to rapid technological change, which increases the stability of related cash flows.  Additionally, the Company believes each of its businesses in its balanced portfolio is a leader in the industries and major markets the Company serves.  Due to these factors, the Company is confident in its future ability to generate positive cash flows from operations.

Cash Flow Summary

The Company’s cash flows from operating, investing and financing activities, as reflected in the Condensed Consolidated Statements of Cash Flows, are summarized in the following table:

	Three Months Ended
	March 31
(In millions)	2013			2012
Net cash provided (used) by:
Operating activities	$	3.4		$	(1.4	)
Investing activities	(40.2		)	(32.3		)
Financing activities	36.4			47.6
Effect of exchange rate changes on cash	(1.9		)	1.6
Net change in cash and cash equivalents	$	(2.3	)	$	15.4

Cash Provided (Used) by Operating Activities— Net cash provided by operating activities in the first three months of 2013 was $3.4 million, an increase of $4.8 million from the first three months of 2012.  The increase is primarily due to net income in the first quarter of 2013 compared with a net loss in the first quarter of 2012; timing of accounts payable disbursements, partially offset by the timing of accounts receivables receipts; changes in other assets and liabilities as detailed below; and restructuring program non-cash expenses in 2012 which were not repeated in 2013.

Included in the Cash flows from operating activities section of the Condensed Consolidated Statement of Cash Flows is the caption Other assets and liabilities. For the three months ended March 31, 2013 and 2012 decreases in this line item were $22.2 million and $4.0 million, respectively. The major components of this line item include the net impact of defined benefit pension plan funding, fluctuations in advances from customers and vendor prepayments. A summary of these components for the periods presented is as follows:

	Three Months Ended
	March 31
(In millions)	2013			2012
Net cash provided by (used in):
Change in net defined benefit pension liabilities	$	(12.0	)	$	(14.8	)
Change in advance on contracts from customers	(10.3		)	(0.5		)
Change in prepaid expenses	(3.3		)	6.4
Other	3.4			4.9
Total	$	(22.2	)	$	(4.0	)

Cash Used by Investing Activities— Net cash used in investing activities in the first three months of 2013 was $40.2 million, an increase of $7.9 million from the first three months of 2012.  The increase was primarily due to reduced cash proceeds from sales of assets.

Cash Provided by Financing Activities— Net cash provided by financing activities in the first three months of 2013 was $36.4 million, a decrease of $11.3 million from the first three months of 2012.  The change was primarily due to a decrease in year-over-year net cash borrowings and lower contributions from noncontrolling interests.

The following table summarizes the Company's debt and capital positions at March 31, 2013 and December 31, 2012:

(Dollars in millions)	March 31 2013			December 31 2012
Notes payable and current maturities	$	16.6		$	11.8
Long-term debt	1,010.6			957.4
Total debt	1,027.2			969.3
Total equity	874.6			861.6
Total capital	$	1,901.8		$	1,830.9
Total debt to total capital (a)	54.0		%	52.9		%

(a) Calculated as Total debt/Total capital.

The Company’s debt as a percent of total capital increased in the first three months of 2013 due principally to increased borrowings under the Company's multi-year revolving credit agreement, partially offset by the increase in total equity as a result of higher net income for the first three months of 2013.

31

Debt Covenants

The credit agreement governing the Company's multi-year revolving credit facility contains covenants that stipulate a maximum debt to capital ratio of 60%, limit the proportion of subsidiary consolidated indebtedness to a maximum of 10% of consolidated tangible assets and specify a minimum ratio of total consolidated earnings before interest, taxes, depreciation and amortization (“EBITDA”) to consolidated interest charges of 3.0:1.  The Company’s 5.75% and 2.70% notes include covenants that require the Company to offer to repurchase the notes at 101% of par in the event of a change of control of the Company or disposition of substantially all of the Company’s assets in combination with a downgrade in the Company’s credit rating to non-investment grade.  At March 31, 2013, the Company was in compliance with these covenants with a debt to capital ratio (as defined by the covenants) of 55.0% and a ratio of consolidated EBITDA to consolidated interest charges of 7.5:1.  The proportion of subsidiary consolidated indebtedness to consolidated tangible assets approximated 2.5% at March 31, 2013. Based on balances at March 31, 2013, the Company could increase borrowings by approximately $240 million and still be in compliance with its debt covenants.  Alternatively, keeping all other factors constant, the Company’s equity could decrease by approximately $163 million and the Company would still be within its debt covenants.  The Company expects to continue to be in compliance with these debt covenants for at least the next twelve months.

Cash and Value-Based Management

The Company has various cash management systems throughout the world that centralize cash in various bank accounts where it is economically justifiable and legally permissible to do so.  These centralized cash balances are then redeployed to other operations to reduce short-term borrowings and to finance working capital needs or capital expenditures.  Due to the transitory nature of cash balances, they are normally invested in bank deposits that can be withdrawn at will or in very liquid short-term bank time deposits and government obligations.  The Company’s policy is to use the largest banks in the various countries in which the Company operates.  The Company monitors the creditworthiness of its banks, and when appropriate, adjusts its banking operations to reduce or eliminate exposure to less credit worthy banks.

At March 31, 2013, the Company's consolidated cash and cash equivalents included $90.0 million held by foreign subsidiaries. At March 31, 2013, less than 10% of the Company's consolidated cash and cash equivalents had regulatory restrictions that would preclude the transfer of funds with and among subsidiaries. The cash and cash equivalents held by foreign subsidiaries also included $33.2 million held in consolidated strategic ventures. The strategic venture agreements may require strategic venture partner approval to transfer funds with and among subsidiaries. While the Company's remaining foreign cash and cash equivalents can be transferred with and among subsidiaries, the majority of these foreign cash balances will be used to support the on-going working capital needs and continued growth of the Company's foreign operations.

The Company plans to continue its strategy of targeted, prudent investing for strategic purposes for the foreseeable future and to make more efficient use of existing investments.  The long-term goal of this strategy is to create stockholder value by improving the Company’s EVA.  Under this program, the Company evaluates strategic investments based upon the investment’s economic profit.  EVA equals after-tax operating profits less a charge for the use of the capital employed to create those profits.  Therefore, value is created when a project or initiative produces a return above the risk-adjusted local country cost of capital.  In the first three months of 2013, EVA was slightly lower than the first three months of 2012, but is expected to be higher for the full year 2013.

The Company currently expects to continue paying dividends to stockholders. In April 2013, the Company declared its 253rd consecutive quarterly cash dividends, payable in August 2013.

The Company’s financial position and debt capacity should enable it to meet current and future requirements. As additional resources are needed, the Company should be able to obtain funds readily and at competitive costs. The Company intends to continue investing in high-return, organic growth projects and prudent, strategic alliances and ventures; reduce debt; and pay cash dividends as a means of enhancing stockholder value.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation

Basis of Presentation

Harsco Corporation (the “Company”) has prepared these unaudited condensed consolidated financial statements based on Securities and Exchange Commission rules that permit reduced disclosure for interim periods.  In the opinion of management, all adjustments (all of which are of a normal recurring nature) that are necessary for a fair presentation are reflected in the unaudited condensed consolidated financial statements.  The December 31, 2012 Condensed Consolidated Balance Sheet information contained in this Quarterly Report on Form 10-Q was derived from the 2012 audited consolidated financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States of America (“U.S. GAAP”) for an annual report.  The unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements, including the notes thereto, included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012.

The Company’s management has evaluated all activity of the Company and concluded that subsequent events are properly reflected in the Company’s unaudited condensed consolidated financial statements and notes as required by U.S. GAAP.

Operating results and cash flows for the three months endedMarch 31, 2013 are not indicative of the results that may be expected for the year ending December 31, 2013.

Restructuring and Related Activities [Abstract]

Restructuring Programs

Restructuring Programs

In recent years, the Company instituted restructuring programs to balance short-term profitability goals with long-term strategies to establish platforms upon which the affected businesses can grow with reduced fixed investment and generate annual operating expense savings.  The restructuring programs have been instituted in response to the continuing impact of global financial and economic uncertainty on the Company’s end markets, particularly in the Company’s Harsco Infrastructure Segment. Restructuring costs incurred in these programs were recorded in the Other (income) expenses line of the Condensed Consolidated Statements of Operations. The timing of associated cash payments is dependent on the type of restructuring cost and can extend over a multi-year period.

2011/2012 Restructuring Program

Under the 2011/2012 Restructuring Program, the Company optimized rental assets and sale inventories by removing non-core assets under an expanded product rationalization and branch structure reduction program undertaken in its Harsco Infrastructure Segment and optimized office structures and reduced global workforce in the Harsco Infrastructure and Harsco Metals & Minerals Segments. Benefits under this program, in the form of reduced costs when compared to 2011, are expected to be approximately $63 million for the full year of 2013. This represents an incremental $8 million in benefits under this program when compared with the benefits realized in 2012. The restructuring accrual for the 2011/2012 Restructuring Program at March 31, 2013 and the activity for the three months then ended are as follows:

(a)    The table does not include $0.3 million of proceeds from asset sales under the 2011/2012 Restructuring Program for this Segment as this item did not impact the restructuring accrual during the three months endedMarch 31, 2013.

Cash expenditures related to the remaining employee termination benefit costs accrual at March 31, 2013 are expected to be paid principally throughout the remainder of 2013 with approximately $6.5 million of exit activity costs for lease terminations expected to be paid over the remaining life of the leases.

Fourth Quarter 2010 Harsco Infrastructure Program

Under the Fourth Quarter 2010 Harsco Infrastructure Program, the Harsco Infrastructure Segment reduced its branch structure; consolidated and/or closed administrative office locations; reduced its global workforce; and rationalized its product lines. The restructuring accrual for the Fourth Quarter 2010 Harsco Infrastructure Program at March 31, 2013 and the activity for the three months then ended are as follows:

(In thousands)	Accrual December 31 2012		Non-cash Charges / Other Adjustments		Cash Expenditures			Foreign Currency Translation			Remaining Accrual March 31 2013
Harsco Infrastructure Segment
Cost to exit activities	$	6,791	$	96	$	(180	)	$	(1	)	$	6,706

Approximately $6.2 million of the March 31, 2013 balance relates to payment of multiemployer pension plan withdrawal liabilities and is expected to be paid through 2023 under contractual payment terms with the related plan administrators.  The remaining balance primarily relates to costs for lease terminations that are expected to be paid over the remaining life of the leases.

Derivative Instruments, Hedging Activities and Fair Value

Derivative Instruments and Hedging Activities

The Company uses derivative instruments, including foreign currency forward exchange contracts, commodity contracts and cross-currency interest rate swaps, to manage certain foreign currency, commodity price and interest rate exposures.  Derivative instruments are viewed as risk management tools by the Company and are not used for trading or speculative purposes.

All derivative instruments are recorded on the Condensed Consolidated Balance Sheets at fair value.  Changes in the fair value of derivatives used to hedge foreign currency denominated balance sheet items are reported directly in earnings along with offsetting transaction gains and losses on the items being hedged.  Derivatives used to hedge forecasted cash flows associated with foreign currency commitments or forecasted commodity purchases may be accounted for as cash flow hedges, as deemed appropriate and if the criteria for hedge accounting are met.  Gains and losses on derivatives designated as cash flow hedges are deferred as a separate component of equity and reclassified to earnings in a manner that matches the timing of the earnings impact of the hedged transactions.  Generally, at March 31, 2013, these deferred gains and losses are reclassified to earnings over 10 to 15 years from the balance sheet date.  The ineffective portion of all hedges, if any, is recognized currently in earnings.

The fair values of outstanding derivative contracts recorded as assets and liabilities on the Condensed Consolidated Balance Sheets at March 31, 2013 and December 31, 2012 were as follows:

	Asset Derivatives (a)			Liability Derivatives (a)

(a) All of the Company's derivatives are recorded in the Condensed Consolidated Balance Sheets as gross amounts and not offset. All of the Company's cross currency interest rate swaps and certain foreign currency forward exchange contracts are transacted under International Swaps and Derivatives Association ("ISDA") documentation. Each ISDA master agreement permits the net settlement of amounts owed in the event of default. The Company's derivative assets and liabilities subject to enforceable master netting arrangements total $0.2 million at March 31, 2013 and $0.1 million at December 31, 2012.

(a)  These gains (losses) offset amounts recognized in cost of services and products sold principally as a result of intercompany or third party foreign currency exposures.

Foreign Currency Forward Exchange Contracts

The Company conducts business in multiple currencies and, accordingly, is subject to the inherent risks associated with foreign exchange rate movements.  The financial position and results of operations of substantially all of the Company’s foreign subsidiaries are measured using the local currency as the functional currency.  Foreign currency-denominated assets and liabilities are translated into U.S. dollars at the exchange rates existing at the respective balance sheet dates. Income and expense items are translated at the average exchange rates during the respective periods.  The aggregate effects of translating the balance sheets of these subsidiaries are deferred and recorded in Accumulated other comprehensive loss, which is a separate component of equity.

The Company uses derivative instruments to hedge cash flows related to foreign currency fluctuations.  Foreign currency forward exchange contracts outstanding are part of a worldwide program to minimize foreign currency exchange operating income and balance sheet exposure by offsetting foreign currency exposures of certain future payments between the Company and its various subsidiaries, suppliers or customers.  These unsecured contracts are with major financial institutions.  The Company may be exposed to credit loss in the event of non-performance by the contract counterparties.  The Company evaluates the creditworthiness of the counterparties and does not expect default by them.  Foreign currency forward exchange contracts are used to hedge commitments, such as foreign currency debt, firm purchase commitments and foreign currency cash flows for certain export sales transactions.

The following tables summarize, by major currency, the contractual amounts of the Company’s foreign currency forward exchange contracts in U.S. dollars at March 31, 2013 and December 31, 2012.  The “Buy” amounts represent the U.S. dollar equivalent of commitments to purchase foreign currencies, and the “Sell” amounts represent the U.S. dollar equivalent of commitments to sell foreign currencies.  The recognized gains and losses offset amounts recognized in cost of services and products sold principally as a result of intercompany or third party foreign currency exposures.

Contracted Amounts of Foreign Currency Forward Exchange Contracts Outstanding at March 31, 2013:

Other currencies	Buy	44,291		January 2013	(71		)
Total		$	434,095		$	(923	)

In addition to foreign currency forward exchange contracts, the Company designates certain loans as hedges of net investments in international subsidiaries.  The Company recorded pre-tax net gains of $1.7 million and pre-tax net losses $6.7 million during the three months endedMarch 31, 2013 and 2012, respectively, into Accumulated other comprehensive loss.

Cross-Currency Interest Rate Swaps

The Company uses cross-currency interest rate swaps in conjunction with certain debt issuances in order to secure a fixed local currency interest rate.  Under these cross-currency interest rate swaps, the Company receives interest based on a fixed or floating U.S. dollar rate and pays interest on a fixed local currency rate based on the contractual amounts in dollars and the local currency, respectively.  The cross-currency interest rate swaps are recorded on the Condensed Consolidated Balance Sheets at fair value, with changes in value attributed to the effect of the swaps’ interest spread recorded in Accumulated other comprehensive loss.  Changes in value attributed to the effect of foreign currency fluctuations are recorded in the statements of operations and offset currency fluctuation effects on the debt principal. The following table indicates the contractual amounts of the Company's cross-currency interest rate swaps at March 31, 2013:

			Interest Rates
(In millions)	Contractual Amount		Receive	Pay
Maturing 2018	$	250.0	Fixed U.S. dollar rate	Fixed euro rate
Maturing 2020	220.0		Fixed U.S. dollar rate	Fixed British pound sterling rate
Maturing 2013 through 2017	10.8		Floating U.S. dollar rate	Fixed rupee rate

Fair Value of Derivative Assets and Liabilities and Other Financial Instruments

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (an exit price).  The Company utilizes market data or assumptions that the Company believes market participants would use in valuing the asset or liability, including assumptions about risk and the risks inherent in the inputs to the valuation technique.

The fair value hierarchy distinguishes between (1) market participant assumptions developed based on market data obtained from independent sources (observable inputs), and (2) an entity’s own assumptions about market participant assumptions based on the best information available in the circumstances (unobservable inputs).  The fair value hierarchy consists of three broad levels, which gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3).  The three levels of the fair value hierarchy are described below:

• Level 1—Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities.

• Level 2—Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly, including quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; inputs other than quoted prices that are observable for the asset or liability (e.g., interest rates); and inputs that are derived principally from or corroborated by observable market data by correlation or other means.

• Level 3—Inputs that are both significant to the fair value measurement and unobservable. 

In instances in which multiple levels of inputs are used to measure fair value, hierarchy classification is based on the lowest level input that is significant to the fair value measurement in its entirety.  The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the asset or liability.

The following table indicates the fair value hierarchy of the financial instruments of the Company at March 31, 2013 and December 31, 2012:

Level 2 Fair Value Measurements

(In thousands)	March 31 2013		December 31 2012
Assets
Foreign currency forward exchange contracts	$	2,200	$	853
Cross-currency interest rate swaps	47,947		39,058
Liabilities
Foreign currency forward exchange contracts	3,671		1,775
Cross-currency interest rate swaps	199		14,346

The Company primarily applies the market approach for recurring fair value measurements and endeavors to utilize the best available information.  Accordingly, the Company utilizes valuation techniques that maximize the use of observable inputs, such as forward rates, interest rates, the Company’s credit risk and counterparties’ credit risks, and which minimize the use of unobservable inputs.  The Company is able to classify fair value balances based on the ability to observe those inputs.  Commodity derivatives, foreign currency forward exchange contracts and cross-currency interest rate swaps are classified as Level 2 fair value based upon pricing models using market-based inputs.  Model inputs can be verified, and valuation techniques do not involve significant management judgment.

The carrying amounts of cash and cash equivalents, accounts receivable, accounts payable, accrued liabilities and short-term borrowings approximate fair value due to the short-term maturities of these assets and liabilities.  At March 31, 2013 and December 31, 2012, the total fair value of long-term debt, including current maturities, was $1.1 billion and $1.0 billion, respectively, compared to a carrying value of $1.0 billion in both periods.  Fair values for debt are based on quoted market prices (Level 1) for the same or similar issues, or on the current rates offered to the Company for debt of the same remaining maturities.

Income Tax Disclosure [Abstract]

Income Taxes

Income Taxes

Income tax expense from continuing operations increased primarily due to higher income from continuing operations being generated in taxable jurisdictions for the three months endedMarch 31, 2013 compared with the three months endedMarch 31, 2012 offset by the expiration of statutes of limitations for uncertain tax positions in certain foreign jurisdictions and the benefits of retroactive law changes. The effective income tax rate related to continuing operations for the three months ended March 31, 2013 was 34.4% compared with (18.1)% for the three months ended March 31, 2012. The effective income tax rate related to continuing operations changed primarily due to decreased losses being generated in jurisdictions where no tax benefit can be recognized. This was offset by the increase in the expiration of statutes of limitations for uncertain tax positions in certain foreign jurisdictions and the benefits of retroactive law changes in 2013 not present in 2012.

An income tax benefit from an uncertain tax position may be recognized when it is more-likely-than-not that the position will be sustained upon examination, based on technical merits, including resolutions of any related appeals or litigation processes. The unrecognized income tax benefit at March 31, 2013 was $30.1 million including interest and penalties.  Within the next twelve months, it is reasonably possible that up to $3.9 million of unrecognized income tax benefits will be recognized upon settlement of tax examinations and the expiration of various statutes of limitations.

The Company recently has been contacted by the Internal Revenue Service to audit the Company's 2010 U.S. income tax return.  The audit is expected to commence during 2013.

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingencies

Commitments and Contingencies

Environmental

The Company is involved in a number of environmental remediation investigations and cleanups and, along with other companies, has been identified as a “potentially responsible party” for certain waste disposal sites.  While each of these matters is subject to various uncertainties, it is probable that the Company will agree to make payments toward funding certain of these activities and it is possible that some of these matters will be decided unfavorably to the Company.  The Company has evaluated its potential liability, and its financial exposure is dependent upon such factors as the continuing evolution of environmental laws and regulatory requirements, the availability and application of technology, the allocation of cost among potentially responsible parties, the years of remedial activity required and the remediation methods selected.  The Condensed Consolidated Balance Sheets as of March 31, 2013 and December 31, 2012 include accruals in Other current liabilities of $1.4 million and $1.9 million, respectively, for environmental matters.  The amounts charged against pre-tax income related to environmental matters totaled $0.3 million and $0.2 million for the three months endedMarch 31, 2013 and 2012, respectively.

The Company evaluates its liability for future environmental remediation costs on a quarterly basis. Although actual costs to be incurred at identified sites in future periods may vary from the estimates (given inherent uncertainties in evaluating environmental exposures), the Company does not expect that any costs that are reasonably possible to be incurred by the Company in connection with environmental matters in excess of the amounts accrued would have a material adverse effect on the Company's financial condition, results of operations or cash flows.

Brazilian Tax Disputes

The Company is involved in a number of tax disputes with federal, state and municipal tax authorities in Brazil. These disputes are at various stages of the legal process, including the administrative review phase and the collection action phase, and include assessments of fixed amounts of principal and penalties, plus interest charges that increase at statutorily determined amounts per month and are assessed on the aggregate amount of the principal and penalties. In addition, the losing party at the collection action or court of appeals phase could be subject to a charge to cover statutorily mandated legal fees, which are generally calculated as a percentage of the total assessed amounts due, inclusive of penalty and interest. A large number of the claims relate to value-added ("ICMS"), services and social security ("INSS") tax disputes. The largest proportion of the assessed amounts relate to ICMS claims filed by the State Revenue Authorities from the State of São Paulo, Brazil (the "SPRA"), encompassing the period from January 2002 to May 2005.

In October 2009, the Company received notification of the SPRA’s final administrative decision regarding the levying of ICMS in the State of São Paulo in relation to services provided to a customer in the State between January 2004 and May 2005.  As of March 31, 2013, the principal amount of the tax assessment from the SPRA with regard to this case is approximately $3 million, with penalty, interest and fees assessed to date increasing such amount by an additional $30 million.  Any increase in the aggregate amount since the Company’s Annual Report on Form 10-K for the year ended December 31, 2012 is due to an increase in assessed interest and statutorily mandated legal fees for the year.  All such amounts include the effect of foreign currency translation.

Another ICMS tax case involving the SPRA refers to the tax period from January 2002 to December 2003, and is still pending at the administrative phase, where the aggregate amount assessed by the tax authorities in August 2005 was $12 million (the amounts with regard to this claim are valued as of the date of the assessment since it has not yet reached the collection phase), composed of a principal amount of approximately $3 million, with penalty and interest assessed through that date increasing such amount by an additional $9 million.  All such amounts include the effect of foreign currency translation.

The Company continues to believe it is not probable that it will incur a loss for these assessments by the SPRA. The Company also continues to believe that sufficient coverage for these claims exists as a result of the Company’s customer’s indemnification obligations and such customer’s pledge of assets in connection with the October 2009 notice, as required by Brazilian procedure.

The Company intends to continue its practice of vigorously defending itself against these tax claims under various alternatives, including judicial appeal. The Company will continue to evaluate its potential liability with regard to these claims on a quarterly basis; however, it is not possible to predict the ultimate outcome of these tax-related disputes in Brazil. No loss provision has been recorded in the Company's consolidated financial statements because the loss contingency is not deemed probable, and the Company does not expect that any costs that are reasonably possible to be incurred by the Company in connection with Brazilian tax disputes would have a material adverse effect on the Company's financial condition, results of operations or cash flows.

Customer Disputes

The Company, through its Harsco Metals & Minerals Segment, provides services to various subsidiaries and affiliates of ArcelorMittal (collectively, "ArcelorMittal") on a number of sites worldwide through long-term service contracts. Currently, ArcelorMittal and the Company are involved in several commercial disputes, a few of which have resulted in legal action. Both the Company and ArcelorMittal are working to resolve these matters. Although results of operations and cash flows for a given period could be adversely affected by a negative outcome in these or other lawsuits, claims and proceedings, management believes that the ultimate outcome of these matters will not have a material adverse effect on the Company's financial condition, results of operations or cash flows.

Other

In the United States, the Company has been named as one of many defendants (approximately 90 or more in most cases) in legal actions alleging personal injury from exposure to airborne asbestos over the past several decades.  In their suits, the plaintiffs have named as defendants, among others, many manufacturers, distributors and installers of numerous types of equipment or products that allegedly contained asbestos.

The Company believes that the claims against it are without merit.  The Company has never been a producer, manufacturer or processor of asbestos fibers.  Any component within a Company product that may have contained asbestos would have been purchased from a supplier.  Based on scientific and medical evidence, the Company believes that any asbestos exposure arising from normal use of any Company product never presented any harmful levels of airborne asbestos exposure, and, moreover, the type of asbestos contained in any component that was used in those products was protectively encapsulated in other materials and is not associated with the types of injuries alleged in the pending suits.  Finally, in most of the depositions taken of plaintiffs to date in the litigation against the Company, plaintiffs have failed to specifically identify any Company products as the source of their asbestos exposure.

The majority of the asbestos complaints pending against the Company have been filed in New York.  Almost all of the New York complaints contain a standard claim for damages of $20 million or $25 million against the approximately 90 defendants, regardless of the individual plaintiff’s alleged medical condition, and without specifically identifying any Company product as the source of plaintiff’s asbestos exposure.

As of March 31, 2013, there are 18,090 pending asbestos personal injury claims filed against the Company.  Of these cases, 17,600 are pending in the New York Supreme Court for New York County in New York State.  The other claims, totaling 490, are filed in various counties in a number of state courts, and in certain Federal District Courts (including New York), and those complaints generally assert lesser amounts of damages than the New York State court cases or do not state any amount claimed.

As of March 31, 2013, the Company has obtained dismissal by stipulation, or summary judgment prior to trial, in 26,715 cases.

In view of the persistence of asbestos litigation nationwide, the Company expects to continue to receive additional claims.  However, there have been developments during the past several years, both by certain state legislatures and by certain state courts, which could favorably affect the Company’s ability to defend these asbestos claims in those jurisdictions.  These developments include procedural changes, docketing changes, proof of damage requirements and other changes that require plaintiffs to follow specific procedures in bringing their claims and to show proof of damages before they can proceed with their claim.  An example is the action taken by the New York Supreme Court (a trial court), which is responsible for managing all asbestos cases pending within New York County in the State of New York.  This Court issued an order in December 2002 that created a Deferred or Inactive Docket for all pending and future asbestos claims filed by plaintiffs who cannot demonstrate that they have a malignant condition or discernible physical impairment, and an Active or In Extremis Docket for plaintiffs who are able to show such medical condition.  As a result of this order, the majority of the asbestos cases filed against the Company in New York County have been moved to the Inactive Docket until such time as the plaintiffs can show that they have incurred a physical impairment.  As of March 31, 2013, the Company has been listed as a defendant in 477 Active or In Extremis asbestos cases in New York County.  The Court’s Order has been challenged by some plaintiffs.

Except with regard to the legal costs in a few limited, exceptional cases, the Company’s insurance carrier has paid all legal and settlement costs and expenses to date related to the Company’s U.S. asbestos cases.  The Company has liability insurance coverage under various primary and excess policies that the Company believes will be available, if necessary, to substantially cover any liability that might ultimately be incurred on these claims.

The Company intends to continue its practice of vigorously defending these claims and cases. It is not possible to predict the ultimate outcome of asbestos-related lawsuits, claims and proceedings due to the unpredictable nature of personal injury litigation, and no loss provision has been recorded in the Company's consolidated financial statements because a loss contingency is not deemed probable or estimable. Despite this uncertainty, and although results of operations and cash flows for a given period could be adversely affected by asbestos-related lawsuits, claims and proceedings, the Company does not expect that any costs that are reasonably possible to be incurred by the Company in connection with asbestos litigation would have a material adverse effect on the Company's financial condition, results of operations or cash flows.

The Company is subject to various other claims and legal proceedings covering a wide range of matters that arose in the ordinary course of business.  In the opinion of management, all such matters are adequately covered by insurance or by established reserves, and, if not so covered, are without merit or are of such kind, or involve such amounts, as would not have a material adverse effect on the financial position, results of operations or cash flows of the Company.

Insurance liabilities are recorded when it is probable that a liability has been incurred for a particular event and the amount of loss associated with the event can be reasonably estimated.  Insurance reserves have been estimated based primarily upon actuarial calculations and reflect the undiscounted estimated liabilities for ultimate losses, including claims incurred but not reported.  Inherent in these estimates are assumptions that are based on the Company’s history of claims and losses, a detailed analysis of existing claims with respect to potential value, and current legal and legislative trends.  If actual claims differ from those projected by management, changes (either increases or decreases) to insurance reserves may be required and would be recorded through income in the period the change was determined.  When a recognized liability is covered by third-party insurance, the Company records an insurance claim receivable to reflect the covered liability.  Insurance claim receivables are included in Other receivables on the Company’s Condensed Consolidated Balance Sheets.  See Note 1, “Summary of Significant Accounting Policies,” to the consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012 for additional information on Accrued Insurance and Loss Reserves.
