NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

1. Basis of Presentation

The accompanying unaudited condensed consolidated financial statements and related disclosures have been prepared in accordance with accounting principles generally accepted in the United States applicable to interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments considered necessary for a fair presentation of Koppers Holdings Inc.’s and its subsidiaries’ (“Koppers”, “Koppers Holdings” or the “Company”) financial position and interim results as of and for the periods presented have been included. All such adjustments are of a normal recurring nature unless disclosed otherwise. Because the Company’s business is seasonal, results for interim periods are not necessarily indicative of those that may be expected for a full year. The Condensed Consolidated Balance Sheet for December 31, 2010 has been summarized from the audited balance sheet contained in the Annual Report on Form 10-K for the year ended December 31, 2010.

The financial information included herein should be read in conjunction with the Company’s audited consolidated financial statements and related notes included in its Annual Report on Form 10-K for the year ended December 31, 2010.

2. Dividends

On May 4, 2011, the Company’s board of directors declared a quarterly dividend of 22 cents per common share, payable on July 6, 2011 to shareholders of record as of May 16, 2011.

3. Business Acquisitions

Koppers Netherlands – On March 1, 2010, the Company acquired 100 percent of the outstanding shares of privately-owned Cindu Chemicals B.V. (“Cindu”) for cash of $21.6 million. Cindu was subsequently renamed Koppers Netherlands B.V. (“Koppers Netherlands”). Koppers Netherlands is a Dutch company which operates a 140,000 metric ton coal tar distillation plant in Uithoorn, Netherlands. The acquisition strengthens the Company’s presence in Europe and increases the Company’s ability to service its export markets.

Acquisition expenses were $1.6 million for the three months ended March 31, 2010 and are charged to selling, general and administrative expenses.

Portec – On December 22, 2010, the Company acquired the rail joint bar business of Portec Rail Products, Inc. located in Huntington, West Virginia. The purchase price was cash of $10.7. The updated allocation of purchase price to acquired assets consisted of inventory totaling $7.1 million, plant and equipment totaling $2.7 million, intangible assets consisting primarily of customer relationships totaling $0.6 million and tax deductible goodwill of $0.3 million. The goodwill is allocated to the Railroad and Utility Products segment.

Other acquisitions – On October 31, 2010, the Company acquired the midwestern United States refined tar business of Stella Jones Inc. for cash of $5.8 million. The final allocation of purchase price to acquired assets consisted of inventory totaling $1.6 million and intangible assets consisting primarily of customer relationships totaling $1.7 million and tax deductible goodwill of $2.5 million. The goodwill is allocated to the Carbon Materials and Chemicals segment.

Pro-forma information – The consolidated pro forma results of operations if the above acquisitions had been completed as of the beginning of the year in 2010 would have been pro forma revenue of $288.1 million and operating profit of $15.9 million for the three months ended March 31, 2010.

4. Fair Value Measurements

Carrying amounts and the related estimated fair values of the Company’s financial instruments as of March 31, 2011 and December 31, 2010 are as follows:


	March 31, 2011				December 31, 2010
	Fair Value		Carrying Value		Fair Value		Carrying Value
(Dollars in millions)
Financial assets:
Cash and cash equivalents, including restricted cash	$	40.5	$	40.5	$	35.3	$	35.3
Investments and other assets^(a)		1.3		1.3		1.3		1.3
Financial liabilities:
Long-term debt (including current portion)	$	351.6	$	320.0	$	324.5	$	296.4

(a)

Excludes equity method investments.

Cash and cash equivalents – The carrying amount approximates fair value because of the short maturity of those instruments.

Investments and other assets – Represents the broker-quoted cash surrender value on universal life insurance policies. This asset is classified as Level 2 in the valuation hierarchy and is measured from values received from financial institutions.

Debt – The fair value of the Company’s long-term debt is estimated based on the market prices for the same or similar issues or on the current rates offered to the Company for debt of the same remaining maturities (Level 2). The fair values of the revolving credit facility approximate carrying value due to the variable rate nature of these instruments.

6. Earnings per Common Share

The computation of basic earnings per common share for the periods presented is based upon the weighted average number of common shares outstanding during the periods. The computation of diluted earnings per common share includes the effect of nonvested nonqualified stock options and restricted stock units assuming such options and stock units were outstanding common shares at the beginning of the period. The effect of antidilutive securities is excluded from the computation of diluted earnings per common share.

The following table sets forth the computation of basic and diluted earnings per common share:


	Three Months Ended March 31,

7. Stock-based Compensation

The amended and restated 2005 Long-Term Incentive Plan (the “LTIP”) provides for the grant to eligible persons of stock options, stock appreciation rights, restricted stock, restricted stock units, performance shares, performance awards, dividend equivalents and other stock-based awards, which are collectively referred to as the awards.

Under the LTIP, the board of directors granted restricted stock units and performance stock units to certain employee participants (collectively, the “stock units”) each year starting in 2007. The restricted stock units vest on the third anniversary of the grant date, assuming continued employment by the participant. Performance stock units granted in 2011 and 2010 each have a two-year performance objective. Performance stock units granted before 2010 have three-year performance objectives. Regardless of whether the measurement period for the applicable performance objective is two or three years, all performance stock units have a three-year period for vesting (if the applicable performance objective is obtained). The applicable performance objective is based upon a multi-year cumulative value creation calculation commencing on the first day of each grant year. The number of performance stock units granted represents the target award and participants have the ability to earn between zero and 150 percent of the target award based upon actual performance. If minimum performance criteria are not

achieved, no performance stock units will vest. The performance stock units originally awarded in 2008 did not vest in 2011 as the related performance objectives were not achieved.

Dividends declared on the Company’s common stock during the restriction period of the stock units are credited at equivalent value as additional stock units and become payable as additional common shares upon vesting. In the event of termination of employment, other than retirement, death or disability, any nonvested stock units are forfeited, including additional stock units credited from dividends. In the event of termination of employment due to retirement, death or disability, pro-rata vesting of the stock units over the service period will result. There are special vesting provisions for the stock units related to a change in control.

Restricted stock units that vest immediately or have one-year vesting periods are also issued under the LTIP to members of the board of directors in connection with annual director compensation and, from time to time, are issued to members of management in connection with employee compensation.

Compensation expense for nonvested stock units is recorded over the vesting period based on the fair value at the date of grant. The fair value of stock units is the market price of the underlying common stock on the date of grant.

The following table shows a summary of the performance stock units outstanding as of March 31, 2011:


Performance Period	Minimum Shares		Target Shares		Maximum Shares
2009 – 2011		0		137,144		205,716
2010 – 2011		0		68,457		102,686
2011 – 2012		0		93,115		139,673

The following table shows a summary of the status and activity of nonvested stock awards for the three months ended March 31, 2011:


	Restricted Stock Units			Performance Stock Units			Total Stock Units			Weighted Average Grant Date Fair Value per Unit
Nonvested at January 1, 2011		121,397			257,002			378,399		$	23.31
Granted		46,277			93,115			139,392		$	40.26
Credited from dividends		3,627			7,693			11,320		$	27.31
Performance stock unit adjustment		0			(50,600	)		(50,600	)	$	38.92
Vested		(23,580	)		0			(23,580	)	$	38.92
Forfeited		(17	)		0			(17	)	$	36.61
Nonvested at March 31, 2011		147,704			307,210			454,914		$	26.06

Stock options to executive officers vest and become exercisable upon the completion of a three-year service period commencing on the grant date. The stock options have a term of 10 years. In the event of termination of employment, other than retirement, death or disability, any nonvested options are forfeited. In the event of termination of employment due to retirement, death or disability, pro-rata vesting of the options over the service period will result. There are special vesting provisions for the stock options related to a change in control.

In accordance with accounting standards, compensation expense for unvested stock options is recorded over the vesting period based on the fair value at the date of grant. The fair value of stock options on the date of grant is calculated using the Black-Scholes-Merton model and the assumptions listed below:


	February 2011 Grant			August 2010 Grant			February 2010 Grant			February 2009 Grant
Grant date price per share of option award	$	40.26		$	20.00		$	28.10		$	15.26
Expected dividend yield per share		2.50	%		2.50	%		2.50	%		2.50	%
Expected life in years		6.5			6.5			6.5			6.5
Expected volatility		60.00	%		62.00	%		62.00	%		51.00	%
Risk-free interest rate		3.02	%		3.05	%		3.05	%		2.05	%
Grant date fair value per share of option awards	$	19.28		$	9.82		$	13.81		$	6.19

The dividend yield is based on the Company’s current and prospective dividend rate which calculates a continuous dividend yield based upon the market price of the underlying common stock. The expected life in years is based on the simplified method permitted under Securities and Exchange Commission Staff Accounting Bulletin No. 107 which calculates the average of the weighted vesting term and the contractual term of the option. This method was selected due to the lack of historical exercise data with respect to the Company. Expected volatility is based on the historical volatility of the Company’s common stock and the historical volatility of certain other similar public companies’ stock. The risk-free interest rate is based on U.S. Treasury bill rates for the expected life of the option.

The following table shows a summary of the status and activity of stock options for the three months ended March 31, 2011:


	Options			Weighted Average Exercise Price per Option		Weighted Average Remaining Contractual Term (in years)		Aggregate Intrinsic Value (in millions)
Outstanding at January 1, 2011		291,591		$	24.63
Granted		73,910		$	40.26
Exercised		(7,150	)	$	29.97
Outstanding at March 31, 2011		358,351		$	27.75		8.04	$	5.4
Exercisable at March 31, 2011		95,568		$	34.70		6.26	$	0.8

Total stock-based compensation expense recognized for the three months ended March 31, 2011 and 2010 is as follows:


	Three Months Ended March 31,
	2011		2010
(Dollars in millions)
Stock-based compensation expense recognized:
Selling, general and administrative expenses	$	0.8	$	0.9
Less related income tax benefit		0.3		0.3
	$	0.5	$	0.6

As of March 31, 2011, total future compensation expense related to non-vested stock-based compensation arrangements totaled $9.8 million and the weighted-average period over which this cost is expected to be recognized is approximately 30 months.

8. Segment Information

The Company has two reportable segments: Carbon Materials & Chemicals and Railroad & Utility Products. The Company’s reportable segments are business units that offer different products. The reportable segments are each managed separately because they manufacture and distribute distinct products with different production processes. The business units have been aggregated into two reportable segments since management believes the long-term financial performance of these business units is affected by similar economic conditions.

The Company’s Carbon Materials & Chemicals segment is primarily a manufacturer of carbon pitch, naphthalene, phthalic anhydride, creosote, carbon black feedstock and carbon black. Carbon pitch is a critical raw material used in the production of aluminum and for the production of steel in electric arc furnaces. Naphthalene is used for the production of phthalic anhydride and as a surfactant in the production of concrete. Phthalic anhydride is used in the production of plasticizers, polyester resins and alkyd paints. Creosote is used in the treatment of wood and carbon black feedstock is used in the production of carbon black. Carbon black is used primarily in the production of rubber tires.

The Company’s Railroad & Utility Products segment sells treated and untreated wood products, manufactured products and services primarily to the railroad and public utility markets. Railroad products include procuring and treating items such as crossties, switch ties and various types of lumber used for railroad bridges and crossings and the manufacture of rail joint bars. Utility products include transmission and distribution poles and pilings.

The Company evaluates performance and determines resource allocations based on a number of factors, the primary measure being operating profit or loss from operations. Operating profit does not include equity in earnings of affiliates, other income, interest expense or income taxes. Operating profit also excludes the operating costs of Koppers Holdings Inc., the parent company of Koppers Inc. The accounting policies of the reportable segments are the same as those described in the summary of significant accounting policies. Intersegment transactions are eliminated in consolidation.

The following table sets forth certain sales and operating data, net of all intersegment transactions, for the Company’s segments for the periods indicated:

9. Income Taxes

Effective Tax Rate

Income taxes as a percentage of pretax income was 35.9 percent for each of the three months ended March 31, 2011 and 2010, respectively. There were no discrete items included in the estimated effective tax rate for either period. The effective tax

rate for the first three months of 2011 differs from the U.S. federal statutory rate of 35.0 percent due to nondeductible expenses (+0.6 percent), state taxes (+1.1 percent) and uncertain tax positions (+0.9 percent) partially offset by the domestic manufacturing deduction (-1.3 percent). With respect to the first three months of 2010, the effective tax rate differs from the federal statutory rate primarily due to nondeductible expenses (+1.2 percent) and state taxes (+0.8 percent) partially offset by the domestic manufacturing deduction (-1.8 percent).

The income tax provision for interim periods is based on an estimated annual effective tax rate, which requires management to make its best estimate of annual pretax income by domestic and foreign jurisdictions and other items that impact taxable income. During the year, management regularly updates estimates based on changes in various factors such as product prices, shipments, product mix, operating and administrative costs, earnings mix by taxable jurisdiction, repatriation of foreign earnings, uncertain tax positions and the ability to claim tax credits such as the non-conventional fuel tax credit. To the extent that actual results vary from the estimates at the end of the first quarter, the actual tax provision recognized for 2011 could be materially different from the forecasted annual tax provision as of the end of the first quarter.

Uncertain Tax Positions

The Company and its subsidiaries files income tax returns in U.S. federal jurisdiction, individual U.S. state jurisdictions and non-U.S. jurisdictions. With few exceptions, the Company is no longer subject to U.S. federal, state and local, or non-U.S. income tax examinations by tax authorities for years before 2005.

As of March 31, 2011 and December 31, 2010, the total amount of unrecognized tax benefits that, if recognized, would affect the effective tax rate, was approximately $3.7 million and $3.5 million, respectively. Unrecognized tax benefits totaled $6.7 million and $6.5 million as of March 31, 2011 and December 31, 2010, respectively. The Company recognizes interest expense and any related penalties from uncertain tax positions in income tax expense. As of March 31, 2011 and December 31, 2010 the Company had accrued approximately $0.7 million.

12. Pensions and Postretirement Benefit Plans

The Company and its subsidiaries maintain a number of defined benefit and defined contribution plans to provide retirement benefits for employees in the U.S., as well as employees outside the U.S. These plans are maintained and contributions are made in accordance with the Employee Retirement Income Security Act of 1974 (“ERISA”), local statutory law or as determined by the board of directors. The defined benefit pension plans generally provide benefits based upon years of service and compensation. Pension plans are funded except for three domestic non-qualified defined benefit pension plans for certain key executives.

All qualified defined benefit pension plans for salaried employees have been closed to new participants and a number of plans, including some plans for hourly employees, have been frozen. Accordingly, these pension plans no longer accrue additional years of service or recognize future increases in compensation for benefit purposes. In addition, a number of pension plans are subject to a “soft” freeze which precludes new employees from entering the defined benefit pension plans.

The defined contribution plans generally provide retirement assets to employee participants based upon employer and employee contributions to the participant’s individual investment account. The Company also provides retiree medical insurance coverage to certain U.S. employees and a life insurance benefit to most U.S. employees. For salaried employees, the retiree medical and retiree insurance plans have been closed to new participants.

Expense related to defined contribution plans totaled $1.5 million and $1.4 million for the three months ended March 31, 2011 and 2010, respectively. Expense related to contributions to multi-employer pension plans totaled $0.2 million and $0.1 million for the three months ended March 31, 2011 and 2010, respectively. Expense related to the Company’s other postretirement benefit plans other than pensions totaled $0.2 million for each of the three months ended March 31, 2011 and March 31, 2010.

The following table provides the components of net periodic benefit cost for the pension plans for the three months ended March 31, 2011 and 2010:

Revolving Credit Facility

The Koppers Inc. revolving credit facility agreement provides for a revolving credit facility of up to $300.0 million at variable rates. Borrowings under the revolving credit facility are secured by a first priority lien on substantially all of the assets of Koppers Inc. and its material domestic subsidiaries. The revolving credit facility contains certain covenants for Koppers Inc. and its restricted subsidiaries that limit capital expenditures, additional indebtedness, liens, dividends, investments or acquisitions. In addition, such covenants give rise to events of default upon the failure by Koppers Inc. and its restricted subsidiaries to meet certain financial ratios. Commitment fees totaled $0.3 million for each of the three months ended March 31, 2011 and 2010 and are charged to interest expense. In March 2011, the Company amended the revolving credit facility to extend the expiration of the facility to March 22, 2015.

As of March 31, 2011, the Company had $247.9 million of unused revolving credit availability for working capital purposes after restrictions from certain letter of credit commitments and other covenants. As of March 31, 2011, $11.3 million of commitments were utilized by outstanding letters of credit.

Senior Notes

The Koppers Inc. 7⁷/8 percent Senior Notes due 2019 (the “Senior Notes”) were issued on December 1, 2009 at an offering price of 98.311 percent of face value, or $294.9 million and have a principal amount at maturity of $300.0 million. The Senior Notes have an effective interest rate yield of 8¹/8 percent per annum. The Senior Notes are unsecured senior obligations that are fully and unconditionally guaranteed by Koppers Holdings and certain of Koppers Inc.’s wholly-owned domestic subsidiaries. The Senior Notes are structurally subordinated to indebtedness under the revolving credit facility.

Interest on the Senior Notes is payable semiannually on December 1 and June 1 each year. On or after December 1, 2014, the Company is entitled to redeem all or a portion of the Senior Notes at a redemption price of 103.938 percent of principal value, declining annually in ratable amounts until the redemption price is equivalent to the principal value on December 1, 2017.

The indenture governing the Senior Notes includes customary covenants that restrict, among other things, the ability of Koppers Inc. and its restricted subsidiaries to incur additional debt, pay dividends or make certain other restricted payments, incur liens, merge or sell all or substantially all of the assets of Koppers Inc. or its subsidiaries or enter into various transactions with affiliates.

Guarantees

The Company’s 60-percent owned subsidiary in China has issued a guarantee of $18.5 million in support of the Company’s 30-percent investment in TKK. The guarantee relates to bank debt incurred by TKK which matures in August 2011 and is expected to be refinanced.

14. Asset Retirement Obligations

The Company recognizes asset retirement obligations for the removal and disposal of residues; dismantling of certain tanks required by governmental authorities; cleaning and dismantling costs for owned rail cars; and cleaning costs for leased rail cars and barges. The following table reflects changes in the carrying values of asset retirement obligations:

16. Commitments and Contingent Liabilities

The Company and its subsidiaries are involved in litigation and various proceedings relating to environmental laws and regulations and toxic tort, product liability and other matters. Certain of these matters are discussed below. The ultimate resolution of these contingencies is subject to significant uncertainty and should the Company or its subsidiaries fail to prevail in any of these legal matters or should several of these legal matters be resolved against the Company or its subsidiaries in the same reporting period, these legal matters could, individually or in the aggregate, be material to the consolidated financial statements.

Legal Proceedings

Coal Tar Pitch Cases. Koppers Inc., along with other defendants, is currently a defendant in lawsuits filed in four states in which the plaintiffs claim they suffered a variety of illnesses (including cancer) as a result of exposure to coal tar pitch sold by the defendants. There are approximately 111 plaintiffs in 62 cases pending as of March 31, 2011 as compared to 111 plaintiffs in 62 cases at December 31, 2010. As of March 31, 2011, there are a total of 58 cases pending in state court in Pennsylvania, one case each pending in state courts in Tennessee and Illinois, and two cases pending in an Indiana state court.

The plaintiffs in all 62 pending cases seek to recover compensatory damages, while plaintiffs in 53 cases also seek to recover punitive damages. The plaintiffs in the 58 cases filed in Pennsylvania state court seek unspecified damages in excess of the court’s minimum jurisdictional limit. The plaintiffs in the two cases filed in Indiana state court also seek damages in an unspecified amount. The plaintiffs in the Tennessee state court case each seek damages of $15.0 million. The plaintiff in the Illinois state court case seeks compensatory damages in excess of $50,000.

The other defendants in these lawsuits vary from case to case and include companies such as Beazer East, Inc., United States Steel Corporation, Honeywell International Inc., Vertellus Specialties Inc., Dow Chemical Company, Rust-Oleum Corporation, UCAR Carbon Company, Inc., Exxon Mobil Corporation, Chemtura Corporation, SGL Carbon Corporation, Alcoa, Inc., and PPG Industries, Inc. Discovery is proceeding in these cases.

The Company has not provided a reserve for these lawsuits because, at this time, the Company cannot reasonably determine the probability of a loss, and the amount of loss, if any, cannot be reasonably estimated. The timing of resolution of these cases cannot be reasonably determined. Although Koppers Inc. is vigorously defending these cases, an unfavorable resolution of these matters may have a material adverse effect on the Company’s business, financial condition, cash flows and results of operations. No trial dates have been set in any of these cases.

Somerville Cases. Koppers Inc. is currently defending five sets of state court cases in Texas (Antu, Baade, Davis, Hensen and Moses) involving approximately 100 plaintiffs who allegedly have worked or resided in Somerville, Texas, where Koppers Inc. has operated a wood treatment plant since 1995. Koppers Inc. has been named, but not served, as a defendant in another Texas state court case (Asselin) involving 11 plaintiffs who allegedly worked or resided in Somerville, Texas. These cases are pending in Burleson County, Texas, and Tarrant County, Texas. The BNSF Railway Company (“BNSF”) has also been named as a defendant in these cases. The complaints allege that plaintiffs have suffered personal injuries (including death, in some cases) resulting from exposure to wood preservative chemicals used at the Somerville, Texas wood treatment plant. The complaints in the Moses, Davis and Asselin cases additionally allege that plaintiffs have suffered property damage.

The complaints seek to recover various damages for each plaintiff, including compensatory and punitive damages within the jurisdictional limits of the court for, among other things, bodily injuries, pain and mental anguish, emotional distress, medical monitoring, medical expenses, diminished earning capacity, permanent disability, physical impairment and/or disfigurement, loss of companionship and society, loss of consortium, devaluation of property, loss of use and enjoyment of personal property, loss of use and enjoyment of real property, property damage, property remediation costs, funeral and burial expenses and lost wages.

Currently, there are a total of 32 plaintiffs in the Moses cases. There are a total of two plaintiffs in the Antu case. There are a total of 45 plaintiffs in the Hensen case, two of whom have claims pending against only the BNSF. The Davis case involves one plaintiff. There are a total of 20 plaintiffs in the Baade case.

No cases pending against Koppers Inc. have discovery completion dates or trial dates.

The Company has not provided a reserve for these matters because, at this time, it cannot reasonably determine the probability of a loss, and the amount of loss, if any, cannot be reasonably estimated. The timing of resolution of these cases cannot be reasonably determined. Although Koppers Inc. is vigorously defending these cases, an unfavorable resolution of these matters may have a material adverse effect on the Company’s business, financial condition, cash flows and results of operations.

Grenada. Koppers Inc., together with various co-defendants (including Beazer East), has been named as a defendant in toxic tort lawsuits in federal court in Mississippi and in state court in Mississippi arising from the operation of the Grenada facility. The complaints allege that plaintiffs were exposed to harmful levels of various toxic chemicals, including creosote, pentachlorophenol, polycyclic aromatic hydrocarbons and dioxin, as a result of soil, surface water and groundwater contamination and air emissions from the Grenada facility. Based on the experience of Koppers Inc. in defending previous toxic tort cases, the Company does not believe that the damages sought by the plaintiffs in the state and federal court cases are supported by the facts of the cases.

Counsel for the plaintiffs in the Grenada state and federal cases and counsel for the Company and Beazer East engaged in mediation on December 2, 2010. As a result of the mediation, a settlement agreement has been reached with respect to all outstanding state and federal cases, except one case pending in state court. The terms of the settlement agreement provide that the pending cases will either be dismissed or, with respect to certain specified cases, plaintiffs’ attorney may withdraw as counsel in lieu of dismissal. As a result of this agreement, the Company included a charge with respect to the state and federal litigation in its financial statements for the year ended December 31, 2010.

Gainesville. Koppers Inc. operated a utility pole treatment plant in Gainesville from 1988 until its closure late in 2009. The property upon which the utility pole treatment plant was located was sold by Koppers Inc. to Beazer East, Inc. in the first quarter of 2010.

In November 2010, a class action complaint was filed in the Circuit Court of the Eighth Judicial Circuit located in Aluchua County, Florida by residential real property owners located in neighborhoods adjacent to the former utility pole treatment plant in Gainesville. The complaint named the Company, Koppers Inc., Beazer East and several other parties as defendants. The complaint alleges that chemicals and contaminants from the plant have contaminated plaintiffs’ properties, have caused property damage and have placed residents and owners of the properties at an elevated risk of exposure to the alleged chemicals. The complaint seeks injunctive relief and compensatory damages for diminution in property values and loss of use and enjoyment. The case was removed to the United States District Court for the Northern District of Florida in December 2010, and plaintiffs have requested that the case be remanded back to state court.

The Company has not provided a reserve for this matter because, at this time, it cannot reasonably determine the probability of a loss, and the amount of loss, if any, cannot be reasonably estimated. The timing of resolution of this case cannot be reasonably determined. Although the Company is vigorously defending this case, an unfavorable resolution of this matter may have a material adverse effect on the Company’s business, financial condition, cash flows and results of operations.

Environmental and Other Litigation Matters

The Company and its subsidiaries are subject to federal, state, local and foreign laws and regulations and potential liabilities relating to the protection of the environment and human health and safety including, among other things, the cleanup of contaminated sites, the treatment, storage and disposal of wastes, the discharge of effluent into waterways, the emission of substances into the air and various health and safety matters. The Company’s subsidiaries expect to incur substantial costs for ongoing compliance with such laws and regulations. The Company’s subsidiaries may also face governmental or third-party claims, or otherwise incur costs, relating to cleanup of, or for injuries resulting from, contamination at sites associated with past and present operations. The Company accrues for environmental liabilities when a determination can be made that a liability is probable and reasonably estimable.

Environmental and Other Liabilities Retained or Assumed by Others. The Company’s subsidiaries have agreements with former owners of certain of their operating locations under which the former owners retained, assumed and/or agreed to indemnify such subsidiaries against certain environmental and other liabilities. The most significant of these agreements was entered into at Koppers Inc.’s formation on December 29, 1988 (the “Acquisition”). Under the related asset purchase agreement between Koppers Inc. and Beazer East, subject to certain limitations, Beazer East retained the responsibility for and agreed to indemnify Koppers Inc. against certain liabilities, damages, losses and costs, including, with certain limited exceptions, liabilities under and costs to comply with environmental laws to the extent attributable to acts or omissions occurring prior to the Acquisition and liabilities related to products sold by Beazer East prior to the Acquisition (the “Indemnity”). Beazer Limited, the parent company of Beazer East, unconditionally guaranteed Beazer East’s performance of the Indemnity pursuant to a guarantee (the “Guarantee”). In 1998, the parent company of Beazer East purchased an insurance policy under which the funding and risk of certain environmental and other liabilities relating to the former Koppers Company, Inc. operations of Beazer East (which includes locations purchased from Beazer East by Koppers Inc.) are underwritten by Centre Solutions (a member of the Zurich Group) and Swiss Re. Beazer East is a wholly-owned, indirect subsidiary of Heidelberg Cement AG. The Indemnity provides different mechanisms, subject to certain limitations, by which Beazer East is obligated to indemnify Koppers Inc. with regard to certain environmental, product and other liabilities and imposes certain conditions on Koppers Inc. before receiving such indemnification, including, in some cases, certain limitations regarding the time period as to which claims for indemnification can be brought. In July 2004, Koppers Inc. and Beazer East agreed to amend the environmental indemnification provisions of the December 29, 1988 asset purchase agreement to extend the indemnification period for pre-closing environmental liabilities through July 2019. As consideration for the amendment, Koppers Inc. paid Beazer East a total of $7.0 million and agreed to share toxic tort litigation defense costs arising from any sites acquired from Beazer East. The July 2004 amendment did not change the provisions of the Indemnity with respect to indemnification for non-environmental claims, such as product liability claims, which claims may continue to be asserted after July 2019.

Qualified expenditures under the Indemnity are not subject to a monetary limit. Qualified expenditures under the Indemnity include (i) environmental cleanup liabilities required by third parties, such as investigation, remediation and closure costs, relating to pre-December 29, 1988, or Pre-Closing, acts or omissions of Beazer East or its predecessors; (ii) environmental claims by third parties for personal injuries, property damages and natural resources damages relating to Pre-Closing acts or omissions of Beazer East or its predecessors; (iii) punitive damages for the acts or omissions of Beazer East and its predecessors without regard to the date of the alleged conduct and (iv) product liability claims for products sold by Beazer East or its predecessors without regard to the date of the alleged conduct. If the third party claims described in sections (i) and (ii) above are not made by July 2019, Beazer East will not be required to pay the costs arising from such claims under the Indemnity. However, with respect to any such claims which are made by July 2019, Beazer East will continue to be responsible for such claims under the

Indemnity beyond July 2019. The Indemnity provides for the resolution of issues between Koppers Inc. and Beazer East by an arbitrator on an expedited basis upon the request of either party. The arbitrator could be asked, among other things, to make a determination regarding the allocation of environmental responsibilities between Koppers Inc. and Beazer East. Arbitration decisions under the Indemnity are final and binding on the parties.

Contamination has been identified at most manufacturing and other sites of the Company’s subsidiaries. Three sites currently owned and operated by Koppers Inc. in the United States are listed on the National Priorities List promulgated under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980, as amended (“CERCLA”). Currently, at the properties acquired from Beazer East (which include all of the National Priorities List sites and all but one of the sites permitted under the Resource Conservation and Recovery Act (“RCRA”)), a significant portion of all investigative, cleanup and closure activities are being conducted and paid for by Beazer East pursuant to the terms of the Indemnity. In addition, other of Koppers Inc.’s sites are or have been operated under RCRA and various other environmental permits, and remedial and closure activities are being conducted at some of these sites.

To date, the parties that retained, assumed and/or agreed to indemnify the Company against the liabilities referred to above, including Beazer East, have performed their obligations in all material respects. The Company believes that, for the last three years ended December 31, 2010, amounts paid by Beazer East as a result of its environmental remediation obligations under the Indemnity have averaged in total approximately $11 million per year. Periodically, issues have arisen between Koppers Inc. and Beazer East and/or other indemnitors that have been resolved without arbitration. Koppers Inc. and Beazer East engage in discussions from time to time that involve, among other things, the allocation of environmental costs related to certain operating and closed facilities.

If for any reason (including disputed coverage or financial incapability) one or more of such parties fail to perform their obligations and the Company or its subsidiaries are held liable for or otherwise required to pay all or part of such liabilities without reimbursement, the imposition of such liabilities on the Company or its subsidiaries could have a material adverse effect on its business, financial condition, cash flows and results of operations. Furthermore, the Company could be required to record a contingent liability on its balance sheet with respect to such matters, which could result in a negative adjustment to the Company’s net worth.

Domestic Environmental Matters. Koppers Inc. has been named as a potentially responsible party (a “PRP”) at the Portland Harbor CERCLA site located on the Willamette River in Oregon. Koppers Inc. has replied to an EPA Information request and has executed a PRP agreement which outlines the process to develop an allocation of past and future costs. The current estimate for past costs incurred in the remedial investigation/feasibility study is approximately $100 million. Koppers Inc. currently operates a coal tar pitch terminal near the site. Koppers Inc. has accrued its estimated cost of participation in the PRP group. Separate from the EPA activities, a natural resources damages assessment is being conducted by a local trustee group. In September 2009, Koppers Inc. received a general notice letter notifying it that it may be a PRP at the Newark Bay CERCLA site. In January 2010, Koppers Inc. submitted a response to the general notice letter asserting that Koppers Inc. is a de minimus party at this site. Other than the estimated cost of participating in the PRP group at the Portland Harbor CERCLA site, the Company has not provided a reserve for these matters because, at this time, it cannot reasonably determine the probability of a loss, and the amount of loss, if any, cannot be reasonably estimated. An unfavorable resolution of these matters may have a material adverse effect on the Company’s business, financial condition, cash flows and results of operations.

The Illinois Environmental Protection Agency (the “IEPA”) has requested that Koppers Inc. conduct a voluntary investigation of soil and groundwater at its Stickney, Illinois carbon materials and chemicals facility. Koppers Inc. is also conducting an investigation of soil and groundwater at a leased terminal site located adjacent to the Stickney facility. Koppers Inc. is conducting such investigations in cooperation with Beazer East. The Company has provided a reserve for this matter totaling $0.8 million as of March 31, 2011.

In August 2005, the Pennsylvania Department of Environmental Protection (the “PADEP”) proposed a fine related to alleged water discharge exceedances from a storm water sewer pipe at the tar distillation facility of Koppers Inc. in Clairton, Pennsylvania. In July 2010, Koppers Inc. reached a final settlement of the fine with the PADEP and executed a consent order with the PADEP. Koppers Inc. also agreed to undertake certain engineering and capital improvements and agreed to contribute the capital improvements, primarily a new sewer line, to the city of Clairton. Accordingly, Koppers Inc. has provided a reserve of $0.6 million related to the new sewer line and PADEP fine as of March 31, 2011. Koppers Inc. expects to complete construction of the sewer line in 2011.

Australian Environmental Matters. Soil and groundwater contamination has been detected at certain of the Company’s Australian facilities. At the Company’s tar distillation facility in Newcastle, New South Wales, Australia, soil contamination from an abandoned underground coal tar pipeline and other groundwater contamination have been detected at a property adjacent to the facility. In December 2006 the Company and the owner of the adjacent property reached an agreement in principle pursuant to which the Company will contribute $1.9 million and the owner of the adjacent property will contribute $6.9 million toward remediation of the property. Subject to the approval of a remediation action plan by local environmental authorities, the agreement in principle provides that the Company will assume responsibility for the management of the remediation effort and will indemnify the current owner for any remediation costs in excess of its agreed contribution. The Company expects to finalize this agreement in the second quarter of 2011. At the completion of the remediation, the agreement in principle provides that the property will be transferred to the Company. The Company has reserved its expected total remediation costs of $1.9 million at March 31, 2011.

Other Australian environmental matters include soil and groundwater remediation at a number of current and former facilities in Australia. With respect to a closed facility in Thornton, Australia, the sale of the property was completed in March 2010 and the buyer assumed all remediation liability. Accordingly, the accrual for remediation at this site was reversed in 2010 and resulted in a decrease to cost of sales of $2.9 million. The Company has reserved $1.2 million for remediation costs at the remaining Australian sites.

Koppers Holdings and each of Koppers Inc.’s wholly-owned material domestic subsidiaries other than Koppers Assurance, Inc. fully and unconditionally guarantee the payment of principal and interest on the Senior Notes. The domestic guarantor subsidiaries include World-Wide Ventures Corporation, Koppers Delaware, Inc., Koppers Concrete Products, Inc., Concrete Partners, Inc., Koppers Ventures LLC and Koppers Asia LLC.

18. Subsidiary Guarantor Information for Shelf Registration

Under a registration statement on Form S-3, Koppers Holdings may sell a combination of securities including common stock, debt securities, preferred stock, depository shares and warrants, from time to time in one or more offerings with an aggregate offering price of up to $325 million. In addition, Koppers Inc. may sell debt securities from time to time under the registration statement. Debt securities may be fully and unconditionally guaranteed, on a joint and several basis, by Koppers Holdings, Koppers Inc. and/or other guarantor subsidiaries which will correspond to subsidiaries in the United States, Europe and Australia. The non-guarantor subsidiaries consist of certain subsidiaries in the United States, China and Mauritius. The guarantor subsidiaries that issue guarantees, if any, will be determined when a debt offering actually occurs under the registration statement and accordingly, the condensed consolidated financial information for subsidiary guarantors will be revised to identify the subsidiaries that actually provided guarantees.

Separate condensed consolidating financial statement information for the parent, Koppers Inc., domestic guarantor subsidiaries, foreign guarantor subsidiaries and non-guarantor subsidiaries as of March 31, 2011 and 2010 and for the three months ended March 31, 2011 and 2010 is as follows:

For additional risk factors affecting our business, see Item 1A. “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2010.

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with the unaudited financial statements and related notes included in Item 1 of this Part I as well as the audited consolidated financial statements and the related notes included in our Annual Report on Form 10-K for the year ended December 31, 2010.

Overview

We are a leading integrated global provider of carbon compounds and commercial wood treatment products and services. Our products are used in a variety of niche applications in a diverse range of end-markets, including the aluminum, railroad, specialty chemical, utility, rubber, concrete and steel industries. We serve our customers through a comprehensive global manufacturing and distribution network, with manufacturing facilities located in the United States, Australia, China, the United Kingdom, Denmark and the Netherlands.

We operate two principal businesses: Carbon Materials & Chemicals (“CM&C”) and Railroad & Utility Products (“R&UP”).

Through our CM&C business, we process coal tar into a variety of products, including carbon pitch, creosote, naphthalene and phthalic anhydride, which are intermediate materials necessary in the production of aluminum, the pressure treatment of wood and the production of carbon black, the production of high-strength concrete, and the production of plasticizers and specialty chemicals, respectively. Through our R&UP business, we believe that we are the largest supplier of railroad crossties to the North American railroads. Our other commercial wood treatment products include the provision of utility poles to the electric and telephone utility industries. We also provide rail joint bar products as well as various services to the railroad industry.

Our CM&C business has entered into a number of strategic transactions during the last year to expand and focus on its core business related to coal tar distillation and derived products. In March 2010, we completed the acquisition of Cindu Chemicals B.V., a coal tar distillation company located in the Netherlands. This company was subsequently renamed Koppers Netherlands B.V. (“Koppers Netherlands”). The revenues from this facility from March 1 through December 31, 2010 amounted to approximately $48 million. In October 2010 we also purchased the midwestern United States refined tar business of Stella Jones Inc. to increase our presence in this market.

Our R&UP business purchased the rail joint bar business of Portec Rail Products, Inc. located in Huntington, West Virginia in December 2010. This acquisition strengthens our product portfolio offerings to our existing Class I and commercial railroad customers in the United States.

Outlook

Trend Overview

Our businesses and results of operations are impacted by various competitive and other factors including (i) the impact of global economic conditions on demand for our products both in the United States and overseas; (ii) raw materials pricing and availability, in particular the amount and quality of coal tar available in global markets, which could be negatively impacted by reductions in steel production; (iii) volatility in oil prices, which impacts the cost of coal tar and certain other raw materials, as well as selling prices and margins for certain of our products including carbon black feedstock and phthalic anhydride; (iv) competitive conditions in global carbon pitch markets; and (v) changes in foreign exchange rates.

Our businesses and results of operations were impacted by the global recession starting in late 2008 and continuing through the first quarter of 2011. Certain key end markets experienced significant global reductions in demand that have negatively impacted our profitability for some of our products. During 2010 our key end markets showed increased stability for our Carbon Materials & Chemicals business.

During 2009 we saw the idling or closure of several aluminum smelters, particularly in North America and Europe, as global production of aluminum declined over previous levels. However, in late 2010 several North American smelters announced that they are planning to increase production and restart some of their previously idled capacity during 2011. We also believe we are well positioned to supply the new Middle Eastern smelters due to our capacity expansions in China.

For the first quarter of 2011, our sales volumes of carbon pitch have increased in all geographic areas where we operate; however, profit margins for carbon pitch have been reduced in certain regions as coal tar costs have increased in response to reduced availability and higher oil prices, and selling prices for carbon pitch have not increased by large enough amounts to recover the increases in raw material costs. We expect this reduction in margins to improve as we move through 2011 as we continue to increase price in an effort to recover the higher raw material costs we have seen to date this year.

Our carbon black business in Australia has been negatively impacted by the weakness of the U.S. dollar because more than half of our carbon black sales are exported and are denominated in U.S. dollars. Additionally, the higher Australian dollar has resulted in increased competition in Australia in terms of imports of carbon black related to our domestic customers. As a result, our second quarter results may be negatively impacted by deteriorating profitability for this business.

Our railroad business was down substantially in 2010 from an unusually strong prior year as we believe the railroads reduced their untreated crosstie purchases and treating volumes in order to reduce inventory levels. However, volumes of crossties have improved significantly in the first quarter of 2011 and we expect this trend to continue for at least the next quarter as the railroads return to more normal inventory levels and the U.S. economy continues to improve and generate more revenues for our Class I and commercial railroad customers.

We produced lower volumes of many of our products in 2010 and 2009 as compared to 2008 which impacted the capacity utilization at our facilities. Lower throughput volumes combined with increasing pressure for price reductions has led us to review our capacity utilization and has resulted in production cutbacks, from time to time, at certain facilities, which can result in lower margins. To the extent these trends continue, we may temporarily idle or permanently close facilities. For example, in December 2009 we announced the sale of our Gainesville utility pole treatment plant, and in the fourth quarter of 2010 we recorded impairment and related charges of $2.2 million related to a wood treating plant in the United States. Utility pole markets in the United States are expected to continue to remain competitive with resulting low margins. We will continue to review underperforming assets and rationalize capacity as necessary to remain competitive in this market and will reduce market share if warranted.

Several of our products, particularly carbon black feedstock and phthalic anhydride, have end market pricing that is linked to oil. During the past few years we have benefited in terms of revenues and profitability from the higher pricing for these products as the cost of coal tar has not increased proportionally with oil. However, when the price of oil declined in late 2008 we saw significant price and profit declines for these products. Additionally, the cost of a portion of our coal tar supply is directly influenced by oil prices, which results in higher costs for our coal tar when oil prices increase.

The availability of our key raw material, coal tar, is linked to levels of metallurgical coke production. As the global steel industry has reduced production of steel and metallurgical coke the volumes of coal tar by-product were also reduced. Our ability to obtain coal tar and the price we are able to negotiate have a significant impact on the level of profitability of our business. Many of our sales contracts include provisions that allow for price increases based on increases in the price of raw materials, which has allowed us to generally maintain profit dollars in our core businesses. However, significant increases in raw material costs can result in margin dilution if only the increased cost of the raw material is passed on to the customer. Additionally, in certain regions such as China that have competing markets for coal tar, or in regions where the available supply of our products exceeds demand, we may not be able to recover raw material cost increases in the selling prices our end products.

Seasonality and Effects of Weather on Operations

Our quarterly operating results fluctuate due to a variety of factors that are outside of our control, including inclement weather conditions, which in the past have affected operating results. Operations at several facilities have been halted for short periods

of time during the winter months. Moreover, demand for some of our products declines during periods of inclement weather. As a result of the foregoing, we anticipate that we may experience material fluctuations in quarterly operating results. Historically, our operating results have been significantly lower in the fourth and first calendar quarters as compared to the second and third calendar quarters. We expect this seasonality trend to continue in future periods.

Results of Operations – Comparison of Three Months Ended March 31, 2011 and 2010

Consolidated Results

Net sales for the three months ended March 31, 2011 and 2010 are summarized by segment in the following table:


	Three Months Ended March 31,				Net Change
	2011		2010		Net Change
(Dollars in millions)
Carbon Materials & Chemicals	$	236.2	$	173.3		+36	%
Railroad & Utility Products		122.9		101.0		+22	%
	$	359.1	$	274.3		+31	%

CM&C net sales increased by $62.9 million or 36 percent due to the following changes in volume, pricing and foreign exchange:


	Price			Volume			Foreign Exchange			Net Change
Carbon Materials^(a)		0	%		+17	%		+2	%		+19	%
Distillates^(b)		+3	%		+4	%		0	%		+7	%
Coal Tar Chemicals^(c)		+3	%		+1	%		0	%		+4	%
Other^(d)		+1	%		+3	%		+2	%		+6	%
Total CM&C		+7	%		+25	%		+4	%		+36	%

(a)

Includes carbon pitch, petroleum pitch and refined tar.

(b)

Includes creosote and carbon black feedstock.

(c)

Includes naphthalene and phthalic anhydride.

(d)

Includes carbon black, benzole, freight and other products.

Carbon materials’ volumes increased primarily due to higher demand for carbon pitch in all geographic regions. The volume increases are due primarily to incremental volumes from the March 2010 acquisition in the Netherlands and increased production from our Chinese operations to supply carbon pitch to smelters in the Middle East.

Distillate pricing and volumes for carbon black feedstock increased three percent in Europe due to increased demand for all operating locations and higher average worldwide oil prices as compared to the prior year. A portion of the increased demand also related to the acquisition in the Netherlands on March 1, 2010.

For coal tar chemicals, the increase in sales for the first quarter of 2011 as compared to 2010 was due to an increase in phthalic anhydride prices which was driven by higher oil prices and an increase in naphthalene volumes related to the March 2010 acquisition in the Netherlands. With respect to other products, volumes for miscellaneous chemical products in China increased three percent as compared to the prior year period.

R&UP net sales increased by $21.9 million or 22 percent due to the following changes in volume, price and foreign exchange:


	Price			Volume			Foreign Exchange			Net Change
Railroad Crossties^(a)		+5	%		+10	%		0	%		+15	%
TSO Crossties^(b)		+1	%		0	%		0	%		+1	%
Distribution Poles		0	%		–1	%		+1	%		0	%
Other^(c)		+1	%		+5	%		0	%		+6	%
Total R&UP		+7	%		+14	%		+1	%		+22	%

(a)

Includes treated and untreated railroad crossties.

(b)

Includes sales from treatment services only (“TSO”).

(c)

Includes joint bar products, creosote, borates, transmission poles, pilings, freight and other treated and untreated lumber products.

Sales prices and volumes for railroad crossties increased five and ten percent, respectively for the three months ended March 31, 2011, driven by higher demand from both commercial and Class I railroad customers. Price increases for treating services increased one percent as a result of adding higher value borate treatment to some of our crossties, and volumes for utility poles decreased one percent. With respect to other products, higher volumes of five percent in the U.S. were realized as a result of the acquisition of the Portec Rail Products, Inc. rail joint bar business in December 2010.

Cost of sales as a percentage of net sales was 87 percent for the quarter ended March 31, 2011 compared to 85 percent for the quarter ended March 31, 2010. The increase in cost of sales as a percentage of net sales is due primarily to raw material cost increases exceeding price increases for the comparable periods, higher inventory carrying costs in the first quarter of 2011 due to stocking for anticipated increases in product demand further into the year and a nonrecurring $2.9 million environmental liability accrual reduction in the first quarter of 2010. Overall, cost of sales was higher between periods due to increased sales of 31 percent.

Depreciation and amortization for the quarter ended March 31, 2011 was $0.4 million higher when compared to the prior year period due partially to foreign exchange translation and additional depreciation from the acquisitions completed in 2010.

Selling, general and administrative expenses for the quarter ended March 31, 2011 were $0.5 million higher when compared to the prior year period primarily due to foreign currency translation.

Other income for the quarter ended March 31, 2011 was $1.6 million lower when compared to the prior year primarily due to the gain on the sale of an Australian property of $1.6 million in 2010.

Interest expense for the quarter ended March 31, 2011 was $6.9 million and was unchanged from the prior year.

Income taxes for the quarter ended March 31, 2011 were $0.8 million higher when compared to the prior year period due primarily to the increase in pretax income of $2.4 million. The Company’s effective income tax rate for the quarter ended March 31, 2011 was 35.9 percent and is unchanged from the prior year period.

North American CM&C sales increased by $7.3 million due primarily to higher volumes for pitch and creosote, higher freight costs, and higher prices for phthalic anhydride totaling $9.5 million, which were partially offset by lower pricing for pitch totaling $3.2 million. Operating profit as a percentage of net sales decreased to two percent from four percent for the prior year, reflecting the impact of lower pitch prices and higher rail and barge demurrage costs, which more than offset the impact of higher prices for phthalic anhydride. Additionally, prior year operating profit was negatively impacted by $1.6 million of expensed acquisition costs related to the acquisition in the Netherlands.

European CM&C sales increased by $23.7 million due primarily to the acquisition in the Netherlands, higher volumes for carbon pitch in the United Kingdom and Denmark totaling $6.5 million, and higher prices for carbon black feedstock and naphthalene totaling $3.8 million. Operating profit as a percentage of net sales was 11 percent, the same as in the prior year.

Australian CM&C sales increased by $7.9 million due primarily to currency exchange rate changes resulting in an increase in sales of $5.1 million combined with higher volumes of carbon pitch totaling $2.1 million. Operating profit as a percentage of net sales increased to eight percent from seven percent in the prior year quarter.

Chinese CM&C sales increased by $22.0 million due primarily to higher volumes of carbon pitch and naphthalene totaling $13.7 million, higher volumes of miscellaneous products totaling $5.3 million, and higher pricing for carbon pitch and carbon black feedstock totaling $3.8 million. Operating profit as a percent of sales increased to three percent from zero percent in the prior year quarter due to profit from the licensing of technology of $0.9 million combined with higher pricing for carbon pitch sold into the Middle East, partially offset by higher raw material costs.

Railroad & Utility Products sales for the three months ended March 31, 2011 increased by $21.9 million as compared to the prior year period due primarily to higher sales volumes for untreated crossties and commercial crossties totaling $12.9 million combined with higher prices for untreated crossties and commercial crossties totaling $4.6 million. Additionally, sales volumes for other railroad products increased by $6.9 million due primarily to incremental sales of rail joint bar products as a result of the Portec Rail Products, Inc. acquisition in December 2010. Operating profit as a percentage of net sales decreased to six percent from seven percent in the prior year as an environmental reserve reversal of $2.9 million related to the sale of a treating plant in Australia in the prior year period more than offset the positive impact from higher crosstie pricing for the three months ended March 31, 2011.

Cash Flow

Net cash used by operating activities was $9.5 million for the quarter ended March 31, 2011 as compared to net cash provided by operating activities of $16.2 million for the quarter ended March 31, 2010. The decrease of $25.7 million in net cash provided by operations is due primarily to higher working capital requirements for inventory and accounts receivable as compared to prior periods.

Net cash used by investing activities was $5.0 million for the quarter ended March 31, 2011 as compared to net cash used by investing activities of $23.1 million for the quarter ended March 31, 2010. The first quarter of 2010 included the acquisition of Cindu totaling $22.0 million partially offset by the proceeds from sale of an Australian property for $1.6 million.

Net cash provided by financing activities was $18.6 million for the quarter ended March 31, 2011 as compared to net cash used by financing activities of $26.7 million for the quarter ended March 31, 2010. The first quarter of 2011 included borrowing of $24.5 million to fund working capital requirements in the business.

Dividends paid were $4.5 million in the quarter ended March 31, 2011 as compared to dividends paid of $4.5 million for the quarter ended March 31, 2010. Dividends paid in both quarters reflect a dividend rate of 22 cents per common share.

On May 4, 2011, our board of directors declared a quarterly dividend of 22 cents per common share, payable on July 6, 2011 to shareholders of record as of May 16, 2011.

Liquidity and Capital Resources

Restrictions on Dividends to Koppers Holdings

Koppers Holdings depends on the dividends from the earnings of Koppers Inc. and its subsidiaries to generate the funds necessary to meet its financial obligations, including the payment of any declared dividend of Koppers Holdings. Koppers Inc.’s credit agreement prohibits it from making dividend payments to us unless (1) such dividend payments are permitted by the indenture governing Koppers Inc.’s Senior Notes and (2) no event of default or potential default has occurred or is continuing under the credit agreement. The indenture governing Koppers Inc.’s Senior Notes restricts its ability to finance our payment of dividends if (1) a default has occurred or would result from such financing, (2) a restricted subsidiary of Koppers Inc. which is not a guarantor under the indenture is not able to incur additional indebtedness (as defined in the indenture), and (3) the sum of all restricted payments (as defined in the indenture) have exceeded the permitted amount (which we refer to as the “basket”) at such point in time.

The basket is governed by a formula based on the sum of a beginning amount, plus or minus a percentage of Koppers Inc’s consolidated net income (as defined in the indenture), plus the net proceeds of Koppers Inc’s qualified stock issuance or

conversions of debt to qualified stock, plus the net proceeds from the sale of or a reduction in an investment (as defined in the indenture) or the value of the assets of an unrestricted subsidiary which is designated a restricted subsidiary. At March 31, 2011 the basket totaled $167.3 million. Notwithstanding such restrictions, the indenture governing Koppers Inc.’s Senior Notes permits an additional aggregate amount of $20.0 million each fiscal year to finance dividends on the capital stock of Koppers Holdings, whether or not there is any basket availability, provided that at the time of such payment, no default in the indenture has occurred or would result from financing the dividends.

In addition, certain required coverage ratios in Koppers Inc.’s revolving credit facility may restrict the ability of Koppers Inc. to pay dividends. See “—Debt Covenants.”

Liquidity

The Koppers Inc. revolving credit facility agreement provides for a revolving credit facility of up to $300.0 million at variable interest rates. Borrowings under the revolving credit facility are secured by a first priority lien on substantially all of the assets of Koppers Inc. and its material domestic subsidiaries. The revolving credit facility contains certain covenants for Koppers Inc. and its restricted subsidiaries that limit capital expenditures, additional indebtedness, liens, dividends and investments or acquisitions. In addition, such covenants give rise to events of default upon the failure by Koppers Inc. and its restricted subsidiaries to meet certain financial ratios.

As of March 31, 2011, we had $247.9 million of unused revolving credit availability for working capital purposes after restrictions by various debt covenants and certain letter of credit commitments. As of March 31, 2011, $11.3 million of commitments were utilized by outstanding letters of credit.

The following table summarizes our estimated liquidity as of March 31, 2011 (dollars in millions):



Cash and cash equivalents	$	40.5
Amount available under revolving credit facility		247.9
Amount available under other credit facilities		15.6
Total estimated liquidity	$	304.0

Our estimated liquidity was $302.6 million at December 31, 2010.

As of March 31, 2011, we had $325.0 million aggregate amount of common stock, debt securities, preferred stock, depositary shares and warrants (or a combination of these securities) available to be issued under our registration statement on Form S-3 filed in 2009.

Our need for cash in the next twelve months relates primarily to contractual obligations which include debt service, purchase commitments and operating leases, as well as for working capital, capital maintenance programs and mandatory defined benefit plan funding. We may also use cash to pursue potential strategic acquisitions. Capital expenditures in 2011, excluding acquisitions, are expected to total approximately $32 million. We believe that our cash flow from operations and available borrowings under the revolving credit facility will be sufficient to fund our anticipated liquidity requirements for at least the next twelve months. In the event that the foregoing sources are not sufficient to fund our expenditures and service our indebtedness, we would be required to raise additional funds.

Debt Covenants

The covenants that affect availability of the revolving credit facility and which may restrict the ability of Koppers Inc. to pay dividends include the following financial ratios:

The fixed charge coverage ratio, calculated as of the end of each fiscal quarter for the four fiscal quarters then ended, is not permitted to be less than 1.10. The fixed charge coverage ratio at March 31, 2011 was 2.1.

The leverage ratio, calculated as of the end of each fiscal quarter for the four fiscal quarters then ended, is not permitted to exceed 4.50. The leverage ratio at March 31, 2011 was 2.34.

We are currently in compliance with all covenants in the credit agreement governing the revolving credit facility.

At March 31, 2011, Koppers Inc. had $300.0 million principal value outstanding of Senior Notes. The Senior Notes include customary covenants that restrict, among other things, our ability to incur additional debt, pay dividends or make certain other restricted payments, incur liens, merge or sell all or substantially all of the assets or enter into various transactions with affiliates. We are currently in compliance with all covenants in the Senior Notes indenture.
