Notes to Condensed Consolidated Financial Statements

(Unaudited)

1. Basis of Presentation

These condensed consolidated financial statements have been prepared by Arch Chemicals, Inc. (with its consolidated subsidiaries, the “Company”), without audit, pursuant to the rules and regulations of the Securities and Exchange Commission and, in the opinion of the Company, reflect all adjustments (consisting of normal accruals) which are necessary to present fairly the results for interim periods. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted pursuant to such rules and regulations; however, the Company believes that the disclosures are adequate to make the information presented not misleading. It is suggested that these condensed consolidated financial statements be read in conjunction with the consolidated financial statements, accounting policies and the notes thereto and management’s discussion and analysis of financial condition and results of operations included in the Company’s Form 10-K for the year ended December 31, 2010. The Company’s Biocides Products segment is seasonal in nature, in particular its HTH water products business as its products are primarily used in the U.S. residential pool market. Therefore, the results of operations for the Company and, in particular, the HTH water products business, for the three and six months ended June 30, 2011 are not indicative of the results to be expected for the entire fiscal year.

On July 10, 2011, the Company entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Lonza Group Ltd., a company organized under the laws of Switzerland (“Lonza”), and LG Acquisition Corp., a Virginia corporation and an indirect wholly owned subsidiary of Lonza (“Merger Sub”), pursuant to which, among other things, Merger Sub has commenced a tender offer (the “Offer”) for all of the outstanding shares of our common stock, at a price of $47.20 per share, net to the seller in cash (the “Offer Price”), subject to the terms and conditions of the Merger Agreement. See Note 18 for further detail.

New Accounting Pronouncements

In October 2009, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2009-13 “Revenue Recognition (Topic 605) – Multiple Deliverable Revenue Arrangements”. FASB ASU 2009-13 addresses the accounting for multiple-deliverable arrangements to enable vendors to account for products or services (deliverables) separately rather than as a combined unit. This guidance establishes a selling price hierarchy for determining the selling price of a deliverable, which is based on: (a) vendor-specific objective evidence; (b) third-party evidence; or (c) estimates. This guidance also eliminates the residual method of allocation and requires that arrangement consideration be allocated at the inception of the arrangement to all deliverables using the relative selling price method. In addition, this guidance significantly expands required disclosures related to a vendor’s multiple-deliverable revenue arrangements. The new standard was effective for the Company on January 1, 2011. The adoption of this pronouncement did not have a material impact on the Company’s condensed consolidated financial statements

Performance Awards

Under its 2009 Long Term Incentive Plan, the Company has granted selected executives and other key employees two types of awards: performance units that vest only upon meeting or exceeding a performance measure

5

Notes to Condensed Consolidated Financial Statements

(Unaudited)

and performance accelerated restricted stock units that vest upon meeting or exceeding a performance measure, or if that measure is not achieved, upon the employee’s remaining in the employ of the Company for a specific period. This component of compensation is designed to encourage the long-term retention of key executives and to tie a major part of executive compensation directly to Company performance and the long-term enhancement of shareholder value. The awards were also designed to recognize and reward achieving or exceeding targeted return on equity (“ROE”). The awards, which are settled partly in cash and partly in shares of the Company’s stock, are earned at the end of a 3-year period provided the ROE target is achieved for that 3^rd year. Performance units that do not meet the performance goal at the end of the 3^rd year expire without payment. For the performance accelerated restricted stock units, if the ROE target is not achieved by the end of the 3^rd year after grant, the units will vest and will be paid out as soon as administratively feasible following the end of the 5^th year after grant if the executive is still employed at the Company. For units granted in 2010, earned payouts of performance units and performance accelerated restricted stock units would equal 100% of the original grant. For units granted in 2011, if the performance target is met or exceeded, payout can vary from 100% to 200% of the original grant, depending on the Company’s ROE. If the ROE target is not met for the performance accelerated restricted stock units, the payout at the end of the 5^th year would equal 100% of the original grant. The Company has estimated that the payout of the units which were granted in 2011 will be at 100%.

The Company accounts for the portion of the award to be settled in shares as an equity-based award, which requires share-based compensation cost to be measured at the grant date, or approval date if awards are amended, based on the fair value of the award. The fair value of the awards is determined and fixed based on the quoted market value of the Company’s stock. The Company uses the straight-line method to recognize the share-based compensation costs related to the awards over the remaining service period. As of June 30, 2011, there were 614,000 performance awards granted; of these awards approximately 308,000 will be paid out in shares of Company stock, if earned. The grant date fair value for the awards to be paid out in shares was $10.3 million.

For the performance awards which are settled in cash, the amount of the payment is based on the market price of the Company’s stock at the time of settlement. During the service period, compensation cost is recognized proportionately based on the Company’s estimate of achieving the financial targets. The performance awards are remeasured to reflect the market price of the Company’s stock at each financial statement date until the award is settled.

The Company had entered into equity total return swap agreements with 400,000 notional shares in order to minimize earnings volatility related to these awards and the Company’s deferred compensation awards (see below for further detail). The Company did not designate the swaps as hedges. Rather, the Company marked the swaps to market and recorded the impact in Selling and administration expenses in the Company’s Condensed Consolidated Statements of Income. The adjustments to the values of the swaps offset the adjustments to the carrying values of the Company’s long-term incentive plan liabilities, which were also recorded in Selling and administration expenses, and there was no significant impact on the Company’s Condensed Consolidated Statements of Income. The swap agreements matured in July 2011, cash settlement occured and the agreements were not renewed. See Note 9 for further detail.

Not including the impact of the equity total return swap agreements, total compensation expense for the three and six months ended June 30, 2011 and 2010 was as follows:

	Three Months Ended June 30,				Six Months Ended June 30,
($ in millions)	2011		2010		2011		2010
Total compensation expense	$	1.2	$	1.1	$	3.1	$	3.4

See Note 9 for a discussion of the impact of the equity total return swap agreements on the Company’s Condensed Consolidated Statements of Income.

As of June 30, 2011, there was $12.7 million of total unrecognized compensation cost related to the unearned payment arrangements, which is expected to be recognized over a weighted-average period of 2 years based on current financial forecasts.

The following table summarizes the performance award activity for the six months ended June 30, 2011 (number of awards in thousands):

As of June 30, 2011, the closing stock price was $34.44 and these outstanding awards have not yet vested.

Deferred Compensation Plans

In 2004, the Company established rabbi trusts (collectively, the “Rabbi Trust”) for its three deferred compensation plans, namely, the 1999 Stock Plan for Non-employee Directors, the Supplemental Contributing Employee Ownership Plan and the Employee Deferral Plan. The following table summarizes the assets and liabilities associated with the Company’s deferred compensation plans as of June 30, 2011 and December 31, 2010:

($ in millions)	June 30, 2011		December 31, 2010
Other assets	$	9.6	$	9.1
Accrued liabilities	$	0.6	$	0.6
Other liabilities		15.0		14.4
Total liabilities	$	15.6	$	15.0

Additionally, the Company had the following amounts recorded as a reduction of equity for the Company’s stock held in the Rabbi Trust as of June 30, 2011 and December 31, 2010:

($ in millions)	June 30, 2011			December 31, 2010
Equity (Reduction of Equity)	$	(1.9	)	$	(1.9	)

3. Earnings Per Share

Basic earnings per common share are computed by dividing net income available to common shareholders by the weighted-average number of common shares outstanding during the period. Diluted earnings per common share are calculated in a similar manner except that the weighted-average number of common shares outstanding during the period includes the potential dilution that could occur if stock options or other contracts to issue common stock were exercised and the dilutive effect of performance awards which will be settled in shares.

The reconciliations between basic and diluted shares outstanding for the three and six months ended June 30, 2011 and 2010 are as follows:

	Three Months Ended June 30,				Six Months Ended June 30,
(in millions)	2011		2010		2011		2010
Basic		25.4		25.1		25.4		25.1
Common equivalent shares from stock options and performance awards using the treasury stock method		0.1		0.1		0.1		0.1
Diluted		25.5		25.2		25.5		25.2

4. Accounts Receivable/Securitization-Related Receivable

7

ARCH CHEMICALS, INC.

Notes to Condensed Consolidated Financial Statements

(Unaudited)

In October 2009, the Company entered into a new securitization program with Market Street Funding LLC and PNC Bank, National Association (“PNC Bank”) by way of an assignment and assumption of the Company’s program with Three Pillars Funding LLC and SunTrust Capital Markets, Inc. Under the program, the Company sells domestic trade accounts receivable, and certain Canadian trade accounts receivable, to Market Street Funding LLC through Arch Chemicals Receivables LLC, a special purpose entity that is consolidated for financial reporting purposes. Additionally, the program provides a letter of credit facility. The amount of funding that the Company can obtain under the program is subject to change based upon the level of eligible receivables, with a maximum amount of $80 million. No more than $30 million of such funding can relate to letters of credit. The program is subject to annual renewal and was renewed for 364 days in October 2010.

Under the program, the fair value of receivables, for which payment of the purchase price by Market Street Funding LLC is deferred, is recorded separately from Accounts receivable, net as a Securitization-related receivable on the accompanying Condensed Consolidated Balance Sheets. The following table summarizes the fair value of these receivables, and the related reserve for credit losses, which is not discounted due to the short term nature of the underlying financial assets, as of June 30, 2011 and December 31, 2010:

($ in millions)	June 30, 2011			December 31, 2010
Securitization-related receivable	$	141.6		$	86.9
Reserve for credit losses		(1.2	)		(1.2	)

The costs of the program for the three and six months ended June 30, 2011 and 2010, which are included in Selling and administration expenses in the accompanying Condensed Consolidated Statements of Income, were as follows:

	Three Months Ended June 30,				Six Months Ended June 30,
(in millions)	2011		2010		2011		2010
Securitization program costs	$	0.2	$	0.3	$	0.3	$	0.5

Under the program, the Company pays a facility fee that is equal to approximately 0.60% of the committed amount of the facility. The Company also incurs costs based on the fair market value of the receivables that are sold under the program and for which payment to Market Street Funding LLC has not been deferred. Such costs are based on the cost of commercial paper issued by Market Street Funding LLC plus a margin of 0.50%. The Company has not recorded an asset or liability related to the servicing responsibility retained as the fees earned for servicing were estimated to approximate fair value.

5. Inventories

Inventories at June 30, 2011 and December 31, 2010 include the following:

($ in millions)	June 30, 2011			December 31, 2010
Raw materials and supplies	$	63.9		$	63.4
Work in process		13.5			10.2
Finished goods		187.2			149.0
Inventories, gross		264.6			222.6
LIFO reserve		(54.7	)		(54.3	)
Inventories, net	$	209.9		$	168.3

Approximately 50 percent of the Company’s inventories are valued by the dollar value last-in, first-out (“LIFO”) method of inventory accounting. Costs of other inventories are determined principally by the first-in, first-out method. Elements of costs in inventories include raw materials, direct labor and manufacturing overhead. Inventories under the LIFO method are based on an annual determination of quantities and costs as of the year-end; therefore, the condensed consolidated financial statements at June 30, 2011 reflect certain estimates relating to projected inventory quantities and costs at December 31, 2011.

6. Discontinued Operations

On March 31, 2010, the Company completed the sale of its industrial coatings business to The Sherwin-Williams Company. Gross proceeds from the sale, before expenses and the final working capital adjustment, were €39.9 million (approximately $54 million). As a result of the sale, the Company recorded an after-tax gain of $6.0 million, which included $27.7 million of net cumulative historical foreign currency translation gains that were recognized at the time of the sale. $5.6 million of the gain was recorded during the six months ended June 30, 2010. Proceeds from the sale are being used for general corporate purposes. The business had sales for the three months ended March 31, 2010 of $34.5 million.

The Company has elected to perform its annual goodwill and other intangibles impairment procedures for all reporting units as of January 1 of each year, or after, if events or circumstances change that could reduce the fair value of a reporting unit below its carrying value. During the first quarter of 2011, the Company completed these procedures and concluded that no impairment existed as of January 1, 2011.

8. Debt

On May 13, 2011, the Company entered into an unsecured $375.0 million revolving credit agreement (“credit agreement”), which matures in May 2016. The credit agreement permits the maximum borrowing amount to be increased to $475.0 million upon the satisfaction of certain conditions, including the agreement of existing or new lenders to increase their existing commitments or extend new commitments, as applicable. The credit agreement restricts the payment of dividends and repurchase of stock to $95.5 million plus 50% of cumulative adjusted net income (loss) for the period beginning March 31, 2011. At June 30, 2011, restricted payments were limited to $109.5 million. The credit agreement contains a quarterly leverage ratio (Debt/EBITDA) covenant not to exceed 4.0 for the first quarter of each year or 3.5 for every other quarter of the year. The facility fees can range from 0.15% to 0.35% depending on the Company’s quarterly leverage ratios (facility fees were 0.25% at June 30, 2011). The Company may select various fixed and floating rate borrowing options, including, but not limited to, LIBOR plus a spread that can range from 0.85% to 1.65% depending on the Company’s quarterly leverage ratios (the spread was 1.125% at June 30, 2011). There was $30.0 million of debt outstanding under the credit agreement at June 30, 2011. The credit agreement replaces the Company’s unsecured $350.0 million revolving credit agreement, dated as of June 15, 2006, under which the Company had $30.0 million of debt outstanding at December 31, 2010. Such amount was recorded in Current portion of long-term debt in the Company’s December 31, 2010 Condensed Consolidated Balance Sheet.

On August 28, 2009, the Company entered into a $150.0 million note purchase and private shelf agreement (the “shelf agreement”) with Prudential Investment Management, Inc. (“Prudential”) and immediately issued $75.0 million of unsecured Series A Senior Notes. The Series A Senior Notes will mature in August 2016 and bear a fixed annual interest rate of 6.70%. The shelf agreement provides for the additional purchase by Prudential of notes, in amounts to be mutually agreed, up to a maximum of $75.0 million through August 2012, on terms to be determined. The shelf agreement restricts the payment of dividends and repurchase of stock to $88.1 million plus 50% of cumulative adjusted net income (loss) for the period beginning June 30, 2009. At June 30, 2011, restricted payments were limited to $109.5 million.

On September 9, 2010, the Company entered into a master note purchase agreement (the “master note agreement”) with certain institutional investors, which provides financing to the Company through the private placement of $250.0 million aggregate principal amount of the Company’s Series 2010-A Senior Notes. The Company issued $250.0 million of Series 2010-A Senior Notes in 2010. The Series 2010-A Senior Notes will mature in December 2017 and bear a fixed annual interest rate of 4.0%. The master note agreement restricts the payment of dividends and repurchase of stock to $99.4 million plus 50% of cumulative adjusted net income (loss) for the period beginning June 30, 2010. At June 30, 2011, restricted payments were limited to $109.5 million.

The credit agreement, shelf agreement and master note agreement each contain a leverage ratio (Debt/EBITDA) covenant and an interest coverage ratio (EBITDA/total interest expense) covenant. The Company was in compliance with both of these covenants at June 30, 2011. At June 30, 2011, the ratios, as defined by the debt agreements, were as follows:

	June 30, 2011		Covenant
Leverage ratio		2.7	Not to exceed 3.5
Interest coverage ratio		8.3	Not to be less than 3.0

At June 30, 2011, the Company had $23.8 million of outstanding letters of credit, $2.9 million of which reduced availability under the Company’s credit agreement. Additionally, at June 30, 2011, the Company had $3.7 million of outstanding letters of guarantee.

At June 30, 2011, the Company had interest rate swap agreements with a total notional value of $30 million. See Note 9 for further discussion.

9. Derivative Instruments and Hedging

Foreign Currency

(Unaudited)

The Company uses foreign currency forward contracts as a means of hedging exposure to foreign currency risk. It is the Company’s policy to hedge up to 80% of its anticipated purchase and sales commitments, and certain balance sheet items, denominated or expected to be denominated in a currency other than the business’ functional currency (principally British pound, euro, Australian dollar, New Zealand dollar, Canadian dollar, Japanese yen and South African rand). Most of the Company’s currency derivatives expire within 1 year. During the three and six months ended June 30, 2011 and 2010, the majority of the Company’s foreign currency forward contracts qualified as effective cash flow hedges. The remainder of the foreign currency contracts did not meet the criteria to qualify for hedge accounting. Additionally, the Company has entered into cross-currency swap agreements to partially hedge its exposure to the variability of future projected foreign currency cash flows through August 2014. The cross-currency swap agreements do not meet the criteria to qualify for hedge accounting.

At June 30, 2011, the Company had forward contracts to sell foreign currencies with U.S. dollar equivalent value of $79.6 million, including contracts with a $55.1 million notional value that are mitigating foreign currency exposure on certain balance sheet items. Additionally, at June 30, 2011, the Company had forward contracts to buy foreign currencies with U.S. dollar equivalent value of $7.0 million and cross-currency swap agreements with a notional value of approximately $3 million.

The counterparties to the Company’s forward contracts and cross-currency swap agreements are major financial institutions. The risk of loss to the Company in the event of nonperformance by a counterparty is not significant. The Company does not use financial instruments for speculative or trading purposes; nor is the Company a party to leveraged derivatives.

The following table displays the fair values at June 30, 2011 and December 31, 2010 of the Company’s foreign currency forward contracts which were designated as hedging instruments, as well as the classification of such amounts in the Company’s Condensed Consolidated Balance Sheets:

As of June 30, 2011 and December 31, 2010, the fair values of the Company’s foreign currency forward contracts which were not designated as hedging instruments were immaterial. Additionally, during the three and six months ended June 30, 2011 and 2010, amounts recorded in the Company’s Condensed Consolidated Statements of Income related to such instruments were immaterial. During the three and six months ended June 30, 2011 and 2010, the amounts which were excluded from effectiveness testing, for foreign currency forward contracts that were designated as hedging instruments, were immaterial.

As of June 30, 2011 and December 31, 2010, the fair values of the Company’s cross-currency swap agreements were immaterial. Additionally, during the three and six months ended June 30, 2011 and 2010, the amounts recorded in the Company’s Condensed Consolidated Statements of Income, related to such swap agreements, were immaterial.

Compensation

The Company is exposed to stock price risk related to its deferred compensation and long-term incentive plans as, for some of the awards, the underlying liabilities are tied to the Company’s stock price. As the Company’s stock price changes, such liabilities are adjusted and the impact is recorded in the Company’s Condensed Consolidated Statements of Income. During 2008, the Company entered into equity total return swap agreements with 400,000 notional shares in order to minimize earnings volatility related to the deferred compensation and long-term incentive plans. During July 2011, the agreements matured, cash settlement occurred and the agreements were not renewed.

The Company did not designate the swaps as hedges. Rather, the Company marked the swaps to market and recorded the impact in Selling and administration expenses in the Company’s Condensed Consolidated Statements of Income. The adjustments to the values of the swaps offset the adjustments to the carrying values of the

Company’s deferred compensation and long-term incentive plan liabilities, which were also recorded in Selling and administration expenses and there was no significant impact on the Company’s Condensed Consolidated Statements of Income.

Debt and Interest

In October 2008, the Company entered into an interest rate swap agreement with a notional value of $30 million. The swap effectively converts the LIBOR based variable rate interest on an additional $30.0 million of debt outstanding under the credit agreement (see Note 8) to a fixed rate of 3.18%. The counterparty to the swap agreement is a major financial institution. The agreement expires in January 2012. Prior to the three months ended June 30, 2011, the Company designated the swap agreement as a cash flow hedge of the risk of variability in future interest payments attributable to changes in the LIBOR rate. During the three months ended June 30, 2011, the Company removed the designation and future changes in the fair value of the swap agreement will be recorded in the Company’s Condensed Consolidated Statement of Income. The Company believes that the impact will be immaterial.

At June 30, 2011 and December 31, 2010, the fair values of the Company’s interest rate swap agreement were immaterial. Additionally, subsequent to the removal of the hedge designation during the three months ended June 30, 2011, the amount which was recorded in the Company’s Condensed Consolidated Statement of Income was immaterial.

During 2010, the Company made voluntary contributions to the Company’s qualified U.S. pension plan. As a result, the Company met the full funding phase-in threshold of the Pension Protection Act of 2006 for the 2011 plan year. There are no cash contribution requirements expected for the Company’s qualified U.S. pension plan in 2011. The Company also has payments due under the non-qualified pension plan and the postretirement benefit plans. These plans are pay as you go, and therefore not required to be funded in advance. Pension expense in 2011 is expected to be comparable to 2010.

Hickson U.K. Pension Plans

During the three and six months ended June 30, 2011 and 2010, the components of net periodic benefit costs for the Hickson U.K. and the Hickson U.K. Senior Executive retirement plans were as follows:

	Three Months Ended June 30,						Six Months Ended June 30,
($ in millions)	2011			2010			2011			2010
Net Periodic Benefit Expense:
Service cost (benefits earned during the period)	$	0.4		$	0.5		$	0.9		$	1.0

Recognized actuarial loss		1.0			0.8			2.0			1.7
Net periodic benefit cost	$	1.9		$	1.7		$	3.7		$	3.4

The Company’s current policy is to fund, at a minimum, amounts as are necessary to provide assets sufficient to meet the benefits to be paid to plan members in accordance with statutory requirements. The minimum funding requirements for the Company’s U.K. pension plans are currently expected to be approximately $25 million to $30 million (or approximately £16 million) in 2011 and then return to $15 million to $20 million (or approximately £10 million) per year thereafter. During the six months ended June 30, 2011, $16.4 million was contributed to the U.K. pension plans. Pension expense in 2011 is expected to be $1 million to $2 million higher than 2010.

11. Comprehensive Income

Comprehensive income includes the change in the cumulative translation adjustment, pension liability adjustments and the change in the fair value of derivative financial instruments that qualify for hedge accounting. Comprehensive income for the three and six months ended June 30, 2011 and 2010, respectively, was as follows:

	Three Months Ended June 30,				Six Months Ended June 30,
($ in millions)	2011		2010		2011			2010
Net income	$	38.0	$	43.5	$	49.8		$	55.3

Net unrealized gain (loss) on derivative instruments		0.3		0.5		(0.4	)		0.1
Pension liability adjustment		2.3		1.9		4.5			3.8
Total other comprehensive income (loss)		6.7		6.5		12.4			(35.0	)
Comprehensive income	$	44.7	$	50.0	$	62.2		$	20.3

The Company does not provide for U.S. income taxes on foreign currency translation adjustments since it does not provide for such taxes on undistributed earnings of foreign subsidiaries, except for the Company’s Canadian subsidiaries and affiliated companies at equity, since the Company intends to continue to reinvest these earnings.

12. Segment Reporting

The Company has organized its business portfolio into two operating segments to reflect the Company’s business strategy. The two segments are Biocides Products and Performance Products. The Biocides Products segment includes three reportable business units: the HTH water products business, the personal care and industrial biocides business and the wood protection business.

Segment operating income includes the equity in earnings of affiliated companies and excludes restructuring expense and impairment expense, if any. The Company includes the equity income (loss) of affiliates in its segment operating results as it believes it to be relevant and useful information for investors as these affiliates are the means by which certain segments participate in certain geographic regions. Furthermore, the Company includes equity income (loss) as a component of segment operating results because the Company includes it to measure the performance of the segment. Other gains and losses that are directly related to the segments are included in segment

operating results. The Company believes the exclusion of restructuring and impairment expenses from segment operating income provides additional perspective on the Company’s underlying business trends and provides useful information to investors by excluding amounts from the Company’s results that the Company believes are not indicative of ongoing operating results.

13. Commitments and Contingencies

There are a variety of non-environmental legal proceedings pending or threatened against the Company.

In May 2005, the Department of Commerce (“DOC”) assessed antidumping duties ranging from approximately 76% to 286% against Chinese producers of chlorinated isocyanurates (“isos”). The Company’s primary Chinese supplier of isos was subject to the 76% rate. As a result, upon importing isos from this supplier, the Company made cash deposits at the rate of 76% of the value of the imported product. At the request of the U.S. isos producers and the Company’s supplier, the DOC conducted a review of the duty rate for the period of December 16, 2004 to May 31, 2006. Upon conclusion of its review, the DOC determined that the rate should be reduced to approximately 20%. As a result of the final determination and the revised rate, the Company recorded a net pre-tax benefit of $12.1 million in the fourth quarter of 2007. The U.S. isos producers appealed the DOC’s determination to the Court of International Trade, which delayed the processing of the full refund the Company was expecting to receive. During the appellate process a revised preliminary rate of approximately 9% was established, but was further challenged. On April 15, 2011, the Court of International Trade issued its decision on the remaining item and the Company does not anticipate a material change in the rate. On July 15, 2011, the DOC submitted its revised rate of approximately 9% for court approval. Provided that this revised rate is approved by the Court of International Trade, the Company would recognize additional income of approximately $3 million. Therefore, the total net cash proceeds the Company expects to receive is approximately $15 million.

At the request of the Company’s supplier, the DOC also initiated an administrative review to determine the final rate for the period of June 1, 2006 through May 31, 2007, during which time the 76% rate also applied. The DOC has determined that the final rate for the Company’s supplier for this period should be reduced from 76% to less than 1%. As a result, the Company recorded a net pre-tax benefit of $12.7 million in the third quarter of 2008 (which included $1.2 million of interest income). The U.S. isos producers appealed the DOC’s determination to the Court of International Trade. The appeal is delaying the cash refund (approximately $14 million) of the duty to the Company and may result in a change of the duty rate for this review period. The Company believes that the resolution of this matter is not likely to have a material adverse effect on its results of operations and cash flows.

At the request of the Company’s supplier, the DOC also initiated an administrative review to determine the final rate for the period of June 1, 2008 to May 31, 2009, during which time the Company paid duty rates of approximately 20% for part of the period and approximately 1% for the remainder of the period. During the fourth quarter of 2010, the DOC made its final determination that changed the Company’s antidumping duty rate for the entire period to approximately 3%. As a result of this final determination, the Company recorded a pre-tax benefit of $0.1 million in the fourth quarter of 2010. The U.S. isos producers appealed the DOC’s determination to the Court of International Trade. The appeal is delaying the cash refund of the duty to the Company and may result in a change of the duty rate for this review period. The Company believes that the resolution of this matter is not likely to have a material adverse effect on its results of operations and cash flows.

At the request of the Company’s supplier, the DOC also initiated an administrative review to determine the final rate for the period of June 1, 2009 to May 31, 2010, during which time the Company paid a duty rate of approximately 1% for part of the period and approximately 20% for the remainder of the period. During the second quarter of 2011, the DOC issued a preliminary rate of approximately 0%. Provided that the final rate is consistent with the preliminary rate, the Company would recognize additional income of approximately $4 million.

Based upon the final determination for the period of June 1, 2008 through May 31, 2009, the Company began paying cash deposits for imports at a rate of approximately 3% during the fourth quarter of 2010.

An administrative review has also commenced to determine the final rate for the period of June 1, 2010 to May 31, 2011.

Along with its primary Comprehensive General Liability (“CGL”) insurer, Arch Coatings France S.A. (“ACF”), a subsidiary of the Company, is a defendant in a lawsuit filed in France by a builder of pleasure boats. The suit alleges that the formulation of certain varnish coatings previously supplied by ACF for application to interior woodwork on approximately 5,200 boats made by the plaintiff was defective in that, under certain conditions, the varnish will bubble and peel. The plaintiff has identified 554 boats in need of repair and the plaintiff

claims that it has expended €4.5 million (approximately $6.4 million) to repair 513 of those boats. In August 2008, ACF was advised by its primary CGL insurer that it was denying coverage for this loss. During 2011, ACF and that insurer concluded an agreement resolving the coverage dispute. ACF sold its assets in the sale of the industrial coatings business to Sherwin-Williams, but has retained the liability for the lawsuit. In July 2011, the parties reached an agreement on the terms of a settlement, the performance of which will not have a material adverse effect on the Company. At June 30, 2011, ACF had €1.4 million (approximately $2.0 million) accrued for this matter.

In December 2007, as a result of an income tax audit of Nordesclor, the Company was notified by the Brazilian tax authorities that the Company would be assessed R$4.9 million (approximately $3.1 million) for alleged tax deficiencies related to the 2002 tax year. In accordance with the purchase agreement that was signed in conjunction with the acquisition of Nordesclor, the Company’s former joint venture partner is responsible for approximately 50% of this assessment. The Company believes the deficiency notice is without merit and, in January 2008, the Company protested the assessment to the first level administrative court. The Company received an unfavorable decision on this protest and has protested the assessment to the second level administrative court. The Company believes that the resolution of this matter is not likely to have a material adverse effect on its results of operations and cash flows.

Additionally, the Company has been notified by the Brazilian tax authorities of various assessments, totaling approximately R$9 million (approximately $6 million), related to alleged non-income tax deficiencies for tax years ranging from 1988 to 2003. The Company has recorded a liability of R$2.7 million (approximately $1.7 million) for any assessments for which it is probable that the Company will be unable to successfully defend itself. The Company believes that the remainder of the assessments are without merit. The Company believes that the resolution of this matter is not likely to have a material adverse effect on its results of operations and cash flows.

During 2003, the Company sold its sulfuric acid business. The Company has received a claim from the current owner of that business. The claimant asserts that, under certain provisions of the agreement for the sale of the business, the Company must indemnify the claimant for certain environmental penalties and compliance costs the claimant will incur under a settlement the claimant reached with the U.S. Environmental Protection Agency. The claimant alleges that such penalties and costs approximate $2.4 million. The Company is currently investigating the validity of the claimant’s assertions. The Company believes that the resolution of this matter is not likely to have a material adverse effect on its results of operations and cash flows.

In March 2010, the owner of a new U.S. patent, relating to methods of using particulate copper wood preservatives, filed a lawsuit against the Company, two of the Company’s subsidiaries, and three customers of the Company’s wood protection business. In the suit, the patent owner claimed that use of certain wood preservatives manufactured and sold by the Company’s wood protection business infringed the patent. The complaint requested several forms of relief, including an unspecified amount of damages and a permanent injunction against infringement of the patent. During 2011, the parties settled the matter and the case was dismissed. The settlement did not have a material impact on the Company. The costs associated with the settlement are included in the results for the six months ended June 30, 2011.

In October 2010, the French taxing authorities notified the Company that it is responsible for paying additional duties in connection with certain products imported into France from October 2005 through May 2007 due to errors in the invoices prepared by the supplier. During the fourth quarter of 2010, the Company recorded a €1.4 million (approximately $2.0 million) liability related to this claim. The Company believes that the resolution of this matter is not likely to have a material adverse effect on its results of operations and cash flows.

The Company is being sued by the current owner of a former Hickson site in Italy for remediation of environmental contaminants on that site. The owner originally sought compensation of €2.2 million (approximately $3.1 million) for the remediation of the site, but recently indicated that it should be awarded €12.6 million (approximately $18.0 million). The trial commenced in May 2011, with additional briefings due through September 2011. Based on remediation actions completed in 2008, the Company believes it has no further obligation at the site. The local authorities, however, continue to review the condition of the site and may require additional work and risk assessments to be performed. Although the site was related to the Company’s industrial coatings business, liability for this lawsuit has been retained by the Company notwithstanding the sale of the business to Sherwin-Williams. The Company believes that the resolution of this matter is not likely to have a material adverse effect on its results of operations and cash flows.

In 1999, Olin and the Company entered into an agreement that specifies that the Company is only responsible for certain environmental liabilities at the Company’s then current operating plant sites and certain offsite locations. Olin retained the liability for all former Olin plant sites and former waste disposal sites. The Company has also become subject to environmental exposures and potential liabilities in the U.S. and abroad with respect to the businesses it purchased. In connection with the acquisitions of Hickson International and Koppers Arch Wood Protection (Aust) Pty Ltd, the Company acquired certain environmental exposures and potential liabilities of current and past operation sites which have been accrued for in the accompanying condensed consolidated financial statements.

In connection with the disposition of the industrial coatings business on March 31, 2010, the Company provided indemnification for the costs of remediation necessary to comply with applicable environmental laws in relation to certain specifically identified pre-closing environmental contamination and non-compliances at the sites used in the business at the time of disposal. Although there are no monetary caps or time limits applicable to the Company’s obligation to indemnify for the remediation costs, the Company estimates the potential exposure to be approximately $1.0 million. At June 30, 2011, the Company had a liability recorded for such amount in Other liabilities in the Company’s Condensed Consolidated Balance Sheet. The Company also provided indemnification for certain other unknown environmental matters relating to the pre-closing operations of the industrial coatings business. This indemnification obligation is subject to both time limits (three years in the case of penalties for non-compliance with applicable environmental laws and permits and seven years in the case of offsite and former property environmental contamination) and a €5 million (approximately $7 million) aggregate monetary cap on all warranty and environmental matters arising out of the transaction (other than the remediation costs associated with the specifically identified onsite contamination and non-compliances discussed above). All other liabilities relating to environmental matters at the sites, and arising in connection with the industrial coatings business before March 31, 2010 have been assumed by the purchaser.

Environmental exposures are difficult to assess for numerous reasons, including the identification of new sites, developments at sites resulting from investigatory studies and remedial activities, advances in technology, changes in environmental laws and regulations and their application, the scarcity of reliable data pertaining to identified sites, the difficulty in assessing the involvement and financial capability of the other potentially responsible parties and the Company’s ability to obtain contributions from other parties and the lengthy time periods over which site remediation occurs. It is possible that some of these matters (the outcomes of which are subject to various uncertainties) may be resolved unfavorably against the Company.

There are a variety of non-environmental legal proceedings pending or threatened against the Company. There have been no significant changes in the status of such items, other than those described above, during the six months ended June 30, 2011.

14. Income Taxes

The total amount of unrecognized tax benefits at June 30, 2011 was $13.8 million, compared to $11.7 million at December 31, 2010. The $2.1 million increase was principally due to current year and prior year tax positions. The unrecognized tax benefits at June 30, 2011 will impact the Company’s annual effective tax rate if recognized. The Company expects to recognize $4.7 million of the remaining $13.8 million of unrecognized tax benefits prior to June 30, 2012, upon the expiration of the period to assess tax in various federal, state and foreign taxing jurisdictions.

The Company is subject to U.S. federal income tax, as well as income tax of multiple foreign and state jurisdictions. The Company’s federal income tax returns for 2008 and 2009 are currently under examination by the Internal Revenue Service. Additionally, the tax years 2007 through 2009 remain open to examination in the United Kingdom (“U.K.”), Italy, Brazil and China, which are major taxing jurisdictions where the Company is subject to foreign taxes.

During the six months ended June 30, 2011, the Company recorded a non-recurring income tax benefit of $6.4 million related to the Company’s tax planning strategy to maximize the realizability of its deferred tax assets principally related to its U.K. pension liabilities.

During the third quarter of 2011, legislation was enacted in the U.K. to reduce the corporate tax rate from 27% to 25%. The Company has significant U.K. deferred tax assets. As a result of the enactment of this

18

ARCH CHEMICALS, INC.

(Unaudited)

legislation, the Company would reduce its U.K. deferred tax assets and record expense of approximately $1 million to $2 million.

15. Fair Value Measurements

FASB ASC 820 establishes a framework for measuring fair value. The framework requires fair value to be determined based on the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants.

The valuation techniques required by FASB ASC 820 are based upon observable and unobservable inputs. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s market assumptions. These two types of inputs create the following fair value hierarchy:

• Level 1 – Quoted prices (unadjusted) for identical assets and liabilities in active markets that the Company has the ability to access at the measurement date.

• Level 2 – Quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; and inputs other than quoted prices that are observable for the asset or liability, including interest rates, yield curves and credit risks, or inputs that are derived principally from or corroborated by observable market data through correlation.

• Level 3 – Significant inputs to the valuation model are unobservable and are primarily based on internally derived assumptions surrounding the timing and amount of expected cash flows.

The following section describes the valuation methodologies the Company uses to measure different assets and liabilities at fair value.

Rabbi Trust and Deferred Compensation Liability

All investments in the Company’s Rabbi Trust are recorded at fair value, except for the Company’s common stock, which is recorded at cost. Additionally, the related deferred compensation liability is recorded at fair value. The Company uses market prices to determine the fair values of these investments and the deferred compensation liability. The investments and the deferred compensation liability are included in Level 1.

Derivatives

The Company has foreign currency forward contracts, cross-currency swaps, interest rate swaps and equity total return swaps recorded at fair value. The fair value for the foreign currency forward contracts is determined using prices from active over-the-counter markets. The cross-currency swap agreements are valued using models which are based on market observable inputs, including foreign currency spot rates, foreign currency forward rates and interest rates. The interest rate swap agreements are valued using models that are based on market observable inputs, including LIBOR rates and yield curves. The Company’s equity total return swap agreements are also valued using models that are based on market observable inputs, principally the Company’s stock price. All derivatives are included in Level 2.

Securitization

Under the Company’s amended securitization program, the Company records receivables for which the payment of the purchase price by Market Street Funding LLC has been deferred, at fair value as a Securitization-related receivable on the accompanying Condensed Consolidated Balance Sheets. Such fair value includes a reserve for credit losses. The receivables are not discounted due to the short-term nature of the underlying financial assets. The Securitization-related receivable is included in Level 3 and net payments of the purchase price which were deferred (received) by Market Street Funding LLC during the three and six months ended June 30, 2011 were as follows:

	Three Months Ended June  30,				Six Months Ended June 30,
($ in millions)	2011		2010		2011		2010
Net payments of the purchase price deferred (received) by Market Street Funding LLC	$	17.2	$	20.2	$	54.7	$	10.9

During the six months ended June 30, 2011 there were no transfers between Level 1 and Level 2.

16. Financial Instruments

The carrying values of Cash and cash equivalents, Accounts receivable and Accounts payable approximate fair values due to the short-term maturities of these instruments.

The fair value of the Company’s borrowings, if any, under its existing credit agreement, approximates book value due to the relatively short period such debt is expected to be outstanding and the fact that the interest rates on the borrowings are reset every 1 to 6 months. The fair value of the Company’s $75.0 million of borrowings under

20

ARCH CHEMICALS, INC.

(Unaudited)

the shelf agreement was approximately $86 million at June 30, 2011. The fair value of the Company’s $250.0 million of borrowings under the master note agreement was approximately $251 million at June 30, 2011. The fair value of the Company’s Short-term borrowings approximates the book value due to the floating interest rate terms and the short maturity of the instruments.

17. Restructuring and Impairment

On August 24, 2010, the Company announced its decision to consolidate into one facility in Alpharetta, Georgia most of its U.S. research and development and technical service activities currently conducted at three facilities. The facilities impacted by this consolidation are New Castle, Delaware; Cheshire, Connecticut; and Conley, Georgia.

During the three and six months ended June 30, 2011, the Company incurred $0.3 million and $0.6 million, respectively, of relocation-related costs due to the consolidation and $0.2 million and $0.2 million, respectively, of other costs due to the consolidation. Additionally, during 2010, the Company recorded a $0.7 million charge for estimated employee severance costs. Most of these costs will be paid by the end of 2011.

Additionally, during 2010, the Company recorded a $1.2 million impairment charge related to its New Castle, Delaware facility and the Company has recorded the facility in Assets held for sale in the Company’s June 30, 2011 and December 31, 2010 Condensed Consolidated Balance Sheets. The fair value of the facility was determined based upon market data.

The following table summarizes the activity related to the restructuring and impairment costs:

($ in millions)	Relocation – Related and Severance Costs			Asset Impairment			Other Costs			Total
Provision	$	0.7		$	1.2		$	0.0		$	1.9
Utilized		0.0			(1.2	)		0.0			(1.2	)
Payments		0.0			0.0			0.0			0.0
Balance at December 31, 2010		0.7			0.0			0.0			0.7
Provision		0.6			0.0			0.2			0.8

Balance at June 30, 2011	$	0.9		$	0.0		$	0.0		$	0.9

The total pre-tax charge to consolidate these facilities is estimated to be in the range of $5 million to $7 million. Excluding the amounts which were recorded to date, the remaining charge will consist of (i) $2 million to $3 million of relocation-related and employee severance costs and (ii) $1 million to $2 million of other costs. The Company anticipates that the consolidation will be completed, and the remaining charge recorded, in 2011. The Company has terminated its lease at the Cheshire, Connecticut facility, effective September 30, 2011, with no penalty to the Company.

18. Subsequent Events

On July 10, 2011, the Company entered into a Merger Agreement with Lonza and Merger Sub, pursuant to which, among other things, Merger Sub has commenced a tender offer for all of the outstanding shares of our common stock, at a price of $47.20 per share, net to the seller in cash, subject to the terms and conditions of the Merger Agreement.

Following the consummation of the Offer, and subject to the satisfaction or waiver of certain conditions set forth in the Merger Agreement, Merger Sub will merge with and into the Company (the “Merger”) and the Company will become a wholly owned, indirect subsidiary of Lonza. At the effective time of the Merger, the shares of our common stock not purchased pursuant to the Offer (other than shares held by our subsidiaries or Lonza, Merger Sub or their respective subsidiaries) will be converted into the right to receive an amount in cash equal to the Offer Price, without interest.

Consummation of the Offer is subject to various conditions, including among others, the expiration or termination of applicable waiting periods under the United States Hart-Scott-Rodino Antitrust Improvements Act,

21

ARCH CHEMICALS, INC.

Notes to Condensed Consolidated Financial Statements

(Unaudited)

the receipt of certain other regulatory approvals and other customary closing conditions, each as described in the Merger Agreement. In addition, it is also a condition to the consummation of the Offer that the number of shares of our common stock validly tendered and not withdrawn in accordance with the terms of the Offer, together with the shares of our common stock, if any, then owned by Lonza, Merger Sub or any of their respective subsidiaries, represent more than two-thirds of the outstanding shares of our common stock (determined on a fully diluted basis). Subject to the terms of the Merger Agreement, the Company has granted Merger Sub an option (the “Top-Up Option”) to purchase that number of newly-issued shares of our common stock that is equal to one share more than the amount needed to give Merger Sub ownership of 90% of our outstanding shares of common stock (determined on a fully-diluted basis, assuming exercise of the Top-Up Option). The Top-Up Option is exercisable only if Merger Sub acquires more than two-thirds of the outstanding shares of our common stock pursuant to the Offer or otherwise. Merger Sub will pay the Company the Offer Price for each share acquired upon exercise of the Top-Up Option.

On July 19, 2011, the Company agreed to accept service of a complaint in a purported shareholder class action in the Superior Court of the State of Connecticut in Stamford, captioned GSS 5-08 Trust v. Arch Chemicals, Inc., et al. An amended complaint was filed on August 2, 2011. The amended complaint names as defendants the Company, the members of the Company’s Board (the “Board”), Lonza and Merger Sub and alleges that the members of the Board breached their fiduciary duties to the Company’s shareholders in connection with the sale of the Company and that the Company, Lonza and Merger Sub aided and abetted the purported breaches of fiduciary duties. In support of the plaintiff’s claims, the amended complaint alleges that the proposed transaction between the Company and Merger Sub undervalues the Company and involves an inadequate sale process and preclusive deal protection devices, and that the Board has failed to disclose to shareholders all material information about the proposed transaction. The GSS 5-08 Trust suit seeks to enjoin the transaction, to obtain damages and to impose a constructive trust in favor of plaintiff and the class upon any property and profits received by defendants as a result of wrongful conduct. It also seeks attorneys’ and other fees and costs, in addition to seeking other relief. On July 28, 2011, the Company was served with another complaint, entitled Leonard Ahern v. Arch Chemicals, Inc. et.al. The Ahern suit also is a purported class action, is brought on behalf of the same purported class of shareholders of the Company as the GSS 5-08 Trust suit, and was brought in the Superior Court of the State of Connecticut in Stamford. The Ahern complaint contains similar allegations to those in the amended complaint in the GSS 5-08 Trust suit, and also alleges that our Board ignored conflicts of interest relating to benefits members of the Board would receive as a result of the transaction. The Company believes these lawsuits are without merit and will contest them vigorously.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Overview

In analyzing the results of operations for the Company and its segments, the following matters should be considered. The Company’s Biocides Products segment is seasonal in nature, in particular the HTH water products business. Historically, approximately 40% of the sales in the HTH water products business occur in the second quarter of the fiscal year, as retail sales in the U.S. residential pool market are concentrated between Memorial Day and the Fourth of July. Therefore, interim results for this segment are not indicative of the results to be expected for the entire fiscal year. Segment operating income includes the equity in earnings of affiliated companies and excludes restructuring expense and impairment expense. The Company includes the equity in earnings of affiliated companies in its segment operating results as it believes it to be relevant and useful information for investors as these affiliates are the means by which certain segments participate in certain geographic regions. Furthermore, equity in earnings of affiliated companies are included as a component of segment operating results because the Company includes it to measure the performance of the segment. Other gains and losses that are directly related to the segments are included in segment operating results.

The overall economic environment for our wood protection business was depressed in 2009 as new housing starts were down significantly and consumers continued to be faced with general economic uncertainty. These factors decreased demand for lumber and other construction materials, which lowered the operating results and cash flows of the business. The Company has seen improvement in the results of the wood protection business from 2009, but these results are still below the pre-2009 levels. If there is no recovery over the next several years or if global economic conditions deteriorate, the earnings and cash flows for this business may be significantly impacted, which could impair certain long-lived assets for this business.

Additionally, the depressed economy in 2009 impacted our performance urethanes business, reducing its overall operating results, and persisted into 2010. The performance urethanes business also had a significant contract expire at the end of 2009, which decreased the annual operating income of the business by approximately $12 million. We believe that organic growth and a pipeline of new product offerings should mitigate a portion of this decrease. If there is no recovery over the next several years or if the business is unsuccessful in new product offerings, the earnings and the cash flows for this business may be significantly impacted, which could impair certain long-lived assets for this business.

On July 10, 2011, the Company entered into an agreement and Plan of Merger (the “Merger Agreement”) with Lonza Group Ltd., a Company organized under the laws of Switzerland (“Lonza”) and LG Acquisition Corp., a Virginia Corporation and an indirect wholly owned subsidiary of Lonza (“Merger Sub”), pursuant to which, among other things, Merger Sub commenced a tender offer for all of the outstanding shares of our common stock, at a price of $47.20 per share, net to the seller in cash, subject to the terms and conditions of the Merger Agreement.

The term “Company” as used in Item 2 of this Report means Arch Chemicals, Inc. and its consolidated subsidiaries unless the context indicates otherwise.

Three Months Ended June 30, 2011 Compared to 2010

Sales increased $2.4 million, or one percent, due to higher pricing. Favorable foreign exchange (three percent) was offset by lower volumes. The lower volumes were principally driven by the HTH water products business, primarily due to timing. In particular, different replenishment strategies attributable to a certain mass retail customer shifted a portion of the pool season sales from the second quarter to the third quarter.

Gross margin percentage was 31.4% and 34.1% for 2011 and 2010, respectively. The decrease in gross margin percentage in 2011 was principally due to the HTH water products business and was primarily driven by higher product costs and lower pricing.

Selling and administration expenses as a percentage of sales were 17.1% in 2011 and 17.3% in 2010. Selling and administration expenses were comparable to 2010.

In August 2010, the Company announced its decision to consolidate into one facility in Alpharetta, Georgia most of its existing U.S. research and development (“R&D”) and technical service activities currently conducted at three facilities. During the three months ended June 30, 2011, the Company recorded $0.3 million of relocation-related costs and $0.2 million of other costs related to the consolidation. The total pre-tax charge to consolidate these facilities is estimated to be in the range of $5 million to $7 million. Excluding the amounts which have been recorded to date, the remaining charge will consist of (i) $2 million to $3 million of relocation-related and employee severance costs and (ii) $1 million to $2 million of other costs. The Company anticipates that the consolidation will be completed, and the remaining charge recorded, in 2011.

Interest expense, net, increased $1.0 million principally due to the higher cost of long-term fixed rate borrowings and, to a lesser extent, higher net debt.

The tax rate on income from continuing operations for the three months ended June 30, 2011 and 2010 was 30.7% and 34.0%, respectively. The rate for the three months ended June 30, 2011 was lower than the rate for the three months ended June 30, 2010 due to higher expected taxable income in foreign jurisdictions with lower tax rates, including tax holidays.

Management’s Discussion and Analysis of Financial Condition and Results of Operations - Continued

Income (Loss) from discontinued operations, net, during the three months ended June 30, 2011 represents a change in estimate for a retained contingency of the industrial coatings business.

Six Months Ended June 30, 2011 Compared to 2010

Sales increased $29.2 million, or four percent, due to favorable foreign exchange (two percent), higher volumes (one percent) and higher pricing (one percent). Volumes were impacted in the HTH water products business due to different replenishment strategies attributable to a certain mass retail customer that shifted a portion of the pool season sales from the second quarter to the third quarter.

Gross margin percentage was 29.8% and 32.0% for 2011 and 2010, respectively. The decrease in gross margin percentage in 2011 was principally due to the HTH water products business and was primarily driven by higher product costs and lower pricing.

Selling and administration expenses as a percentage of sales were 19.4% in 2011 and 19.6% in 2010. Selling and administration expenses increased $3.7 million from 2010 principally due to unfavorable foreign exchange and one-time legal-related costs.

In August 2010, the Company announced its decision to consolidate into one facility in Alpharetta, Georgia most of its existing U.S. R&D and technical service activities currently conducted at three facilities. During the six months ended June 30, 2011, the Company recorded $0.6 million of relocation-related costs and $0.2 million of other costs related to the consolidation.

Interest expense, net, increased $2.3 million principally due to the higher cost of long-term fixed rate borrowings and, to a lesser extent, higher net debt.

The tax rate on income from continuing operations for the six months ended June 30, 2011 and 2010 was 20.3% and 34.0%, respectively. The rate for the six months ended June 30, 2011 includes a non-recurring $6.4 million benefit related to the Company’s tax planning strategy to maximize the realizability of its deferred tax assets principally related to its U.K. pension liabilities. Excluding the benefit, the Company’s tax rate was approximately 31%. This rate was lower than the rate for the six months ended June 30, 2010 due to higher expected taxable income in foreign jurisdictions with lower tax rates, including tax holidays.

Income (Loss) from discontinued operations, net, during the six months ended June 30, 2011 represents changes in estimates for retained contingencies of the industrial coatings business.

Income (Loss) from discontinued operations, net, during the six months ended June 30, 2010 represents the results of operations for the industrial coatings business until its sale in March 2010.

The Gain on sale of discontinued operations, net, during the six months ended June 30, 2010 relates to the sale of the industrial coatings business.

Segment Information

The Company has organized its business portfolio into two operating segments to reflect the Company’s business strategy. The two segments are Biocides Products and Performance Products. The Biocides Products segment includes three reportable business units: the HTH water products business, the personal care and industrial biocides business, and the wood protection business. Segment operating income includes the equity in earnings of affiliated companies and excludes restructuring expense and impairment expense. The Company believes the exclusion of restructuring and impairment expense from segment operating income provides additional perspective on the Company’s underlying business trends and provides useful information to investors by excluding amounts from the Company’s results that the Company does not believe are indicative of ongoing operating results.

The Company includes the equity in earnings of affiliated companies in its segment operating results as it believes it to be relevant and useful information for investors as these affiliates are the means by which certain segments participate in certain geographic regions. Furthermore, the Company includes it to measure the

performance of the segment. Other gains and losses that are directly related to the segments are included in segment operating results.

Three Months Ended June 30, 2011 Compared to 2010

Sales decreased $6.8 million, or two percent, as lower volumes (five percent) were partially offset by favorable foreign exchange (three percent).

Operating income decreased $11.5 million due to lower operating income for the HTH water products business.

HTH Water Products

Sales decreased $13.4 million, or six percent, as lower volumes (seven percent) and decreased pricing (one percent) were partially offset by favorable foreign exchange (two percent). The decreased volumes principally related to North America, due to different replenishment strategies attributable to a certain mass retail customer and to a much lesser extent, unseasonable weather during the early part of the swimming pool season. The replenishment strategies negatively impacted the second quarter as shipments were delayed into the third quarter compared to the prior year’s pool season. The lower pricing principally related to the North American mass retail channel and, to a lesser extent, Latin America.

Operating income decreased $15.5 million due to the lower volumes which were mostly due to timing, as well as higher product and operating costs and the decreased pricing.

Personal Care and Industrial Biocides

Sales increased $3.9 million, or five percent, as favorable foreign exchange (four percent) and higher volumes (two percent) were partially offset by lower pricing (one percent). The higher volumes were primarily due to increased demand for biocides used in building products due to expanded applications for the Company’s products in paint applications. Demand for biocides used in antidandruff products was consistent with prior year. The lower pricing principally related to biocides used in industrial applications.

Operating income increased $1.9 million as the impact of foreign currency losses in 2010 and the higher volumes more than offset the lower pricing.

26

Management’s Discussion and Analysis of Financial Condition and Results of Operations - Continued

Wood Protection

Sales increased $2.7 million, or four percent, as favorable foreign exchange (six percent) and higher pricing (five percent) more than offset lower volumes (seven percent). The higher pricing related to price increases in North America and Europe, as well as favorable mix in Europe. Volumes decreased principally due to the weak housing and construction markets in North America, competitive pressures in the North American and Asia-Pacific regions and customer disruptions from natural disasters in the Asia-Pacific region.

Operating income increased $2.1 million as the increased pricing and favorable foreign exchange more than offset higher raw material costs and the lower volumes.

Six Months Ended June 30, 2011 Compared to 2010

Sales increased $6.7 million, or one percent, as favorable foreign exchange (three percent) was partially offset by lower volumes (two percent).

Operating income decreased $14.3 million due to lower operating income for the HTH water products business.

HTH Water Products

Sales decreased $2.1 million, or one percent, as lower volumes (two percent) and lower pricing (one percent) were partially offset by favorable foreign exchange (two percent). The decreased volumes principally related to North America, due to different replenishment strategies attributable to a certain mass retail customer and to a much lesser extent, unseasonable weather during the early part of the swimming pool season. The replenishment strategies negatively impacted the second quarter as shipments were delayed into the third quarter compared to the prior year’s pool season.

Operating income decreased $15.6 million due to the lower volumes, which were mostly due to timing, as well as higher product and operating costs and the decreased pricing.

Personal Care and Industrial Biocides

Sales increased $6.0 million, or four percent, as favorable foreign exchange (three percent) and higher volumes (two percent) more than offset lower pricing (one percent). The higher volumes were primarily due to increased demand for biocides used in building products, partially offset by lower demand for biocides used in antidandruff products. Sales of biocides used in building products grew significantly as a result of increased remodeling activities and expanded applications for the Company’s products in paint applications. Demand for biocides used in antidandruff products declined due to timing of shipments. The lower pricing principally related to biocides used in industrial applications.

Operating income was comparable to prior year as the higher volumes were offset by lower pricing and higher product costs.

Wood Protection

Sales increased $2.8 million, or two percent, as favorable foreign exchange (four percent) and higher pricing (four percent) more than offset lower volumes (six percent). The higher pricing related to price increases in North America and Europe. Volumes decreased in the North American region, due to the weak housing and construction markets and competitive pressures, and in the Asia-Pacific region, due to competitive pressures and customer disruptions from natural disasters.

Operating income increased $1.6 million. Included in 2011 operating income is $1.5 million of one-time legal-related costs for a final resolution of a patent dispute. Excluding the legal-related costs, operating income improved $3.1 million as the increased pricing and favorable foreign exchange more than offset higher raw material costs and the lower volumes.

Three Months Ended June 30, 2011 Compared to 2010

Sales increased $9.2 million, or 20 percent, due to higher volumes (13 percent) and improved pricing (seven percent). Operating income decreased by $0.9 million.

During 2009, Lyondell, a key supplier to the Company’s hydrazine business, terminated all service agreements with the Company. The Company has entered into, or expects to finalize shortly, new service agreements with Lyondell and other third parties to replace most of the terminated service agreements, with the exception of certain services that the Company now performs for itself. The new service agreements with Lyondell operate on a year-to-year basis and, as a result, may be terminated after the initial one year term. BioLab, Inc. (“BioLab”), a subsidiary of Chemtura Corporation, is currently providing several services to the Company at this site, including wastewater treatment services. However, the Company has not finalized a contract with BioLab with respect to the wastewater treatment services. If the new service agreements with Lyondell are terminated or the Company is unable to finalize the wastewater services agreement with BioLab and if the Company is unable to arrange for alternative suppliers or perform such services for itself, there could be a material impact on this segment’s operating results. While the Company does not believe that there will be a significant impact on operating results in 2011, there may be higher capital expenditures to allow the Company to perform the services that are currently being performed by the third parties.

Performance Urethanes

Performance urethanes sales increased $9.4 million, or 22 percent, due to higher volumes (15 percent) and higher pricing (seven percent). Volumes increased 26 percent principally due to increased demand for polyols used in bedding applications. The higher pricing was driven by increased raw material costs. Operating results were comparable as the higher pricing, and to a lesser extent, the improved volumes, were offset by higher raw material costs.

Hydrazine

Hydrazine sales and operating income were comparable with 2010.

Six Months Ended June 30, 2011 Compared to 2010

Sales increased $22.5 million, or 25 percent, due to higher volumes (18 percent) and improved pricing (seven percent). Operating results improved by $0.8 million.

Performance Urethanes

28

Management’s Discussion and Analysis of Financial Condition and Results of Operations - Continued

Performance urethanes sales increased $22.9 million, or 28 percent, due to higher volumes (20 percent) and higher pricing (eight percent). Volumes increased primarily due to increased demand for propylene glycol products used in airports for de-icing and related antifreeze applications. Higher pricing was driven by increased raw material costs. Operating results improved by $1.5 million as the higher pricing, and to a lesser extent, the improved volumes, more than offset higher raw material costs.

Hydrazine

Hydrazine sales were consistent with 2010. Operating income was slightly lower than 2010 principally due to higher plant and freight costs.

Six Months Ended June 30, 2011 Compared to 2010

For the six months ended June 30, 2011, $45.1 million was used in operating activities from continuing operations, compared to $76.1 million provided by operating activities from continuing operations during the six months ended June 30, 2010. The change was principally due to decreased use of the accounts receivable securitization program in 2011 and increased working capital levels for the HTH water products business as it builds its inventory in anticipation of a major technology upgrade at its manufacturing plant in the U.S.

Accounts receivable, net, at June 30, 2011, including amounts sold through the accounts receivable securitization program (see Note 4 of Notes to the Condensed Consolidated Financial Statements), was three percent higher than at June 30, 2010 principally due to the fact that sales during the three months ended June 30, 2011 were higher than the three months ended June 30, 2010. Days sales outstanding (“DSO”) was 50 days at both June 30, 2011 and June 30, 2010. The Company continues to closely monitor its accounts receivable balances and assess the allowance for doubtful accounts. The allowance was $4.6 million at June 30, 2011, compared to $4.4 million at December 31, 2010.

Inventories, net at June 30, 2011 were 29 percent higher than at June 30, 2010. At June 30, 2011 the Company’s inventory months on hand (“MOH”) was 2.9, compared to 2.5 at June 30, 2010. The increase in Inventories, net at June 30, 2011 versus June 30, 2010 is principally due to lower sales volumes during the three months ended June 30, 2011 than during the three months ended June 30, 2010, increased inventory levels for the HTH water products business as it builds its inventory in anticipation of a major technology upgrade at its manufacturing plant in the U.S. and the timing of sales to mass retail accounts in the HTH water products business. The obsolescence reserve was $9.9 million at June 30, 2011, compared to $9.6 million at December 31, 2010.

Capital expenditures for the first six months of 2011 were $14.3 million higher than the first six months of 2010 principally due to the start of a major technology upgrade at the Company’s HTH water products manufacturing plant in the U.S. and the consolidation and expansion of three of the Company’s U.S. research and development functions into a new leased facility.

On March 31, 2010, the Company completed the sale of its non-strategic industrial coatings business to Sherwin-Williams. Total net proceeds from the sale are expected to be approximately $43 million, net of expenses. During 2010, the Company received all of the proceeds and $5.6 million of transaction costs have been paid to date. The Company estimates making the payment of the remaining transaction costs during 2011.

Management’s Discussion and Analysis of Financial Condition and Results of Operations - Continued

Debt repayments, net of borrowings, were $93.0 million lower during the six months ended June 30, 2011 than during the six months ended June 30, 2010. The change was partially due to a greater use of the securitization program during 2010 and the Company using proceeds from the sale of the industrial coatings business in 2010 to repay debt.

On June 15, 2011, the Company paid a quarterly dividend of $0.20 on each share of common stock. During the six months ended June 30, 2011 and June 30, 2010, total dividends paid to shareholders were $10.1 million and $10.0 million, respectively.

On May 13, 2011, the Company entered into an unsecured $375.0 million revolving credit agreement (“credit agreement”), which matures in May 2016. The credit agreement permits the maximum borrowing amount to be increased to $475.0 million upon the satisfaction of certain conditions, including the agreement of existing or new lenders to increase their existing commitments or extend new commitments, as applicable. The Company’s credit agreement contains a quarterly leverage ratio (Debt/EBITDA) covenant not to exceed 4.0 for the first quarter of each year or 3.5 for every other quarter of the year. At June 30, 2011, the Company’s quarterly leverage ratio, as defined in the credit agreement, was 2.7. Additionally, the credit agreement contains an interest coverage ratio (EBITDA/total interest expense) covenant not to be less than 3.0. At June 30, 2011, the Company’s interest coverage ratio, as defined in the credit agreement, was 8.3. The Company was in compliance with both of these covenants at June 30, 2011. The credit agreement also restricts the payment of dividends and repurchase of stock to $95.5 million plus 50% of cumulative adjusted net income (loss) for the period beginning March 31, 2011. Restricted payments were limited to $109.5 million at June 30, 2011. The facility fees can range from 0.15% to 0.35% depending on the Company’s quarterly leverage ratios. The Company may select various fixed and floating rate borrowing options, including, but not limited to, LIBOR plus a spread that can range from 0.85% to 1.65% depending on the Company’s quarterly leverage ratios. At June 30, 2011, there was $30.0 million of debt outstanding under the credit agreement and the Company had $342.1 million of available borrowings. The credit agreement replaces the Company’s unsecured $350.0 million revolving credit agreement, dated as of June 15, 2006.

On August 28, 2009, the Company entered into a $150.0 million note purchase and private shelf agreement (the “shelf agreement”) with Prudential Investment Management, Inc. (“Prudential”) and immediately issued $75.0 million of unsecured Series A Senior Notes. The Series A Senior Notes will mature in August 2016 and bear a fixed annual interest rate of 6.70%. The shelf agreement provides for the additional purchase by Prudential of notes, in amounts to be mutually agreed, up to a maximum of $75.0 million through August 2012, on terms to be determined. The shelf agreement contains a quarterly leverage ratio covenant not to exceed 3.5 and an interest coverage ratio covenant not to be less than 3.0, both of which are consistent with the credit agreement. At June 30, 2011 the Company’s quarterly leverage ratio, as defined in the shelf agreement, was 2.7 and the Company’s interest coverage ratio, as defined in the shelf agreement, was 8.3. The Company was in compliance with both of these covenants at June 30, 2011. Additionally, the shelf agreement restricts the payment of dividends and repurchase of stock to $88.1 million plus 50% of cumulative adjusted net income (loss) for the period beginning June 30, 2009. At June 30, 2011, restricted payments were limited to $109.5 million.

On September 9, 2010, the Company entered into a master note purchase agreement (the “master note agreement”) with certain institutional investors, which provides financing to the Company through the private placement of $250.0 million aggregate principal amount of the Company’s Series 2010-A Senior Notes. The Company issued $250.0 million of the Series 2010-A Senior Notes during 2010. The Series 2010-A Senior Notes will mature in December 2017 and bear a fixed annual interest rate of 4.0%. The master note agreement contains a quarterly leverage ratio covenant not to exceed 3.5 and an interest coverage ratio covenant not to be less than 3.0, both of which are consistent with the credit agreement and shelf agreement. At June 30, 2011, the Company’s quarterly leverage ratio, as defined in the master note agreement, was 2.7 and the Company’s interest coverage ratio, as defined in the master note agreement, was 8.3. The Company was in compliance with both of these covenants at June 30, 2011. Additionally, the master note agreement restricts the payment of dividends and repurchase of stock to $99.4 million plus 50% of cumulative adjusted net income (loss) for the period beginning June 30, 2010. At June 30, 2011, restricted payments were limited to $109.5 million.

On October 6, 2009, the Company entered into an accounts receivable securitization program with Market Street Funding LLC and PNC Bank, National Association (“PNC Bank”) by way of an assignment and assumption of the Company’s previous program with Three Pillars Funding LLC and SunTrust Capital Markets, Inc. Under the

31

Management’s Discussion and Analysis of Financial Condition and Results of Operations - Continued

amended program, the Company can sell domestic trade accounts receivable, and certain Canadian trade accounts receivable, to Market Street Funding LLC through its wholly-owned subsidiary, Arch Chemicals Receivables LLC. Additionally, the program provides a letter of credit facility. The amount of funding that the Company can obtain under the program is subject to change based upon the level of eligible receivables with a maximum amount of $80 million. No more than $30 million of such funding can relate to letters of credit. The amended program is subject to annual renewal. The program was renewed for 364 days in October 2010. See Note 4 of Notes to Condensed Consolidated Financial Statements.

At June 30, 2011, the Company had $23.8 million of outstanding letters of credit, $2.9 million of which reduced availability under the credit agreement. Additionally, at June 30, 2011, the Company had $3.7 million of outstanding letters of guarantee.

The Company believes that the credit agreement, accounts receivable securitization program and cash provided by operations, as well as amounts previously borrowed under the master note agreement and shelf agreement, are adequate to satisfy its liquidity needs for the near future, including financing capital expenditures. However, if the Company’s earnings or cash flows were to fall significantly below current expectations and/or a default condition were triggered under its funding agreements or if the Company’s funding providers do not honor their commitments, a risk exists that the Company would not have sufficient liquidity to meet its operating needs. In addition, adverse developments in the financial markets could reduce the sources of liquidity for the Company.

Although the Company has seen improvement in demand, the turmoil in the global economy throughout 2009 impacted the operating performance of several of the Company’s businesses. As a result, the estimated fair values for some of the Company’s reporting units have been impacted, in particular the performance urethanes and wood protection reporting units. If there is no recovery over the next several years or if global economic conditions deteriorate, the following assets for the wood protection business could become impaired: Goodwill of $45.8 million and/or Long-lived assets (exclusive of Goodwill, Other assets and Investments and advances – affiliated companies at equity) of $55.8 million. In addition to the impact of the turmoil in the U.S. economy, the performance urethanes business had a significant contract expire at the end of 2009, which decreased the annual operating income of the business by approximately $12 million. We believe that organic growth and a pipeline of new product offerings should mitigate a portion of this decrease. If the performance urethanes business’ earnings and/or cash flows were to fall below current expectations due to no recovery in the economy over the next several years, or if the business is unsuccessful with new product offerings, the following assets could become impaired: Goodwill of $4.4 million, and/or Long-lived assets (exclusive of Goodwill, Other assets and Investments and advances – affiliated companies at equity) of $13.3 million.

The Company’s performance urethanes and hydrazine businesses are non-core to its portfolio and are managed for cash that is then invested in growing our core Biocides portfolio. The Company considers these businesses non-core and, therefore, does not expect that they will remain in the portfolio in the long-term. The Company continues to evaluate various strategic options for these businesses, which include possible divestiture. At June 30, 2011, the net assets of the performance urethanes and hydrazine businesses were $38.3 million and $0.6 million, respectively.

As provided in the Biocidal Products Directive (“BPD”), the European Union (“EU”) is reviewing the classification and labeling of a number of chemicals under a new, more wide-ranging procedure. One of the Company’s products, poly hexamethylene biguanide hydrochloride (“PHMB”), which has been on the market for many years providing valuable disinfection, preservation, cleaning and hygiene functions, is one of the chemicals under review. France, in its role as lead reviewer of PHMB under the BPD, has proposed a much more conservative classification of PHMB. PHMB is currently being reviewed by the European Chemicals Agency (“ECHA”) to determine if the French classification should be upheld. If the new classification is upheld, there is the potential for customers electing to discontinue the use of PHMB and PHMB-related products in response to the new classification and such discontinuation could also extend beyond the EU. The Company is actively defending against this new classification of the product as well as developing alternative products. If ECHA does not overturn the classification and the Company’s customers decide to no longer purchase PHMB as a result of this change in classification, the Company’s operating results in the future and up to $13 million of PHMB-related intangible assets could be impacted. In 2010, the Company had approximately $11 million of PHMB sales in Europe and approximately $38 million of PHMB sales worldwide.

In addition, Olin Corporation (“Olin”), who is a major supplier of chlorine and caustic soda to the Company’s HTH water products business, has announced plans to convert its mercury cell Chlor-Alkali plant in Charleston, Tennessee to membrane technology by the end of 2012. The Company does not believe that there will be any significant impact on its operating results in 2011, but if there is any disruption in our supply of chlorine and caustic soda from Olin, whether due to delays in the conversion of the plant or Olin’s inability to deliver product meeting our required specifications after the conversion is completed, the Company would have to arrange for alternative suppliers, which could have a material impact on this business’ operating income and cash flows in the future. The Company’s current supply contract expires at the end of 2011 and the Company is currently negotiating a new contract which may contain higher prices for 2012 and beyond.

During 2010, the Company made voluntary contributions to the Company’s qualified U.S. pension plan. As a result, the Company met the full funding phase-in threshold of the Pension Protection Act of 2006 for the 2011 plan year. There are no cash contribution requirements expected for the Company’s qualified U.S. pension plan in 2011. The Company also has payments due under the non-qualified pension plan and the postretirement benefit plans. These plans are pay as you go, and therefore not required to be funded in advance. The minimum funding requirements for the Company’s U.K. pension plans are currently expected to be approximately $25 million to $30 million (or approximately £16 million) in 2011 and then return to $15 million to $20 million (or approximately £10 million) per year thereafter.

In connection with the pending acquisition of the Company by Lonza Group Ltd., the Company’s Board of Directors has suspended the Company’s dividend.

New Accounting Pronouncements

In June 2011, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2011-05, “Comprehensive Income (Topic 220): Presentation of Comprehensive Income”. ASU 2011-05 allows an entity the option to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. In both choices, an entity is required to present each component of net income along with total net income, each component of other comprehensive income along with a total for other comprehensive income, and a total amount for comprehensive income. ASU 2011-05 eliminates the option to present the components of other comprehensive income as part of the statement of changes in stockholders’ equity. ASU 2011-05 does not change the items that must be reported in other comprehensive income or when an item of other comprehensive income must be reclassified to net income. The pronouncement will be effective for the Company during the three months ended March 31, 2012.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

The Company is exposed to various market risks, including changes in foreign currency exchange rates, interest rates, commodity prices and stock prices. The Company does not enter into derivatives or other financial instruments for trading or speculative purposes in the normal course of business.

Interest Rate Risk

The Company historically has been exposed to interest rate risk. As of June 30, 2011, approximately ninety-five percent of its outstanding borrowings are subject to fixed rates as a result of the new financing arrangements. Based on the Company’s expected 2011 borrowing levels, and the amount of borrowings subject to floating rates, an increase in interest rates of 100 basis points would decrease the Company’s annual results of operations and annual cash flows by approximately $0.1 million.

See Note 9 of Notes to the Condensed Consolidated Financial Statements for detail of the Company’s interest rate swap agreement.

Foreign Currency Risk

At June 30, 2011, the Company had forward contracts to sell foreign currencies with a U.S. dollar equivalent value of $79.6 million, including contracts with a $55.1 million notional value that are mitigating foreign currency exposure on certain balance sheet items. Additionally, at June 30, 2011, the Company had forward contracts to buy foreign currencies with a U.S. dollar equivalent value of $7.0 million and the Company had entered into cross-currency swap agreements with a total notional value of approximately $3 million.

Approximately 30 percent of the Company’s sales and expenses are denominated in currencies other than the U.S. dollar. As a result, the Company is subject to risks associated with its foreign operations, including currency devaluations and fluctuations in currency exchange rates. These exposures from foreign exchange fluctuations can affect the Company’s equity investments and its respective share of earnings (losses), the Company’s net investment in foreign subsidiaries, translation of the Company’s foreign operations for U.S. GAAP reporting purposes and purchase and sales commitments denominated in foreign currencies. The Company enters into forward sales and purchase contracts, cross-currency swap agreements and currency options to manage currency risk from actual and anticipated purchase and sales commitments, and certain balance sheet items, denominated or expected to be denominated in a foreign currency (principally British pound, euro, Australian dollar, New Zealand dollar, Canadian dollar, Japanese yen and South African rand). It is the Company’s policy to hedge up to 80 percent of these transactions during a calendar year. The counterparties to the options and contracts are major financial institutions.

Holding other variables constant, if there were a 10 percent change in foreign currency exchange rates versus the U.S. dollar, the net effect on the Company’s annual cash flows would be an increase (decrease) of between $2 million to $3 million related to the unhedged portion. Any increase (decrease) in cash flows resulting from the Company’s hedge forward contracts would be offset by an equal (decrease) increase in cash flows on the underlying transaction being hedged. The application of U.S. GAAP may cause increased volatility in the Company’s results of operations in the future if the Company changes its policies, or if some of the derivative instruments do not meet the requirements for hedge accounting.

See Note 9 of Notes to the Condensed Consolidated Financial Statements for detail of the Company’s foreign currency forward contracts.

Commodity Price Risk

The Company is exposed to commodity price risk related to the price volatility of natural gas utilized at certain manufacturing sites as well as price volatility of propylene oxide and copper. The purchase requirement of copper is approximately 15 million pounds annually. Depending on market conditions, the Company may purchase derivative commodity instruments to minimize the risk of price fluctuations of natural gas and copper. It is the Company’s policy to hedge up to 80 percent of its natural gas and copper purchases during a calendar year. In general, the Company’s guideline is to hedge a minimum of approximately 50 percent of the Company’s rolling twelve-month copper requirements. At June 30, 2011, the Company had purchase commitments but had no forward contracts to

35

Item 3. Quantitative and Qualitative Disclosures about Market Risk

purchase natural gas and copper. In addition, the Company is exposed to price risk related to the volatility of certain other raw materials including the ongoing purchase of chromic acid and ethylene oxide. Holding other variables constant, a 10 percent adverse change in the price of propylene oxide would decrease the Company’s annual results of operations and annual cash flows between $2 million to $3 million. Additionally, holding other variables constant, a 10 percent adverse change in the price of either chromic acid or copper would decrease the Company’s annual results of operations and annual cash flows between $1 million to $2 million. Additionally, holding other variables constant, a 10 percent adverse change in the price of either natural gas or ethylene oxide, would decrease the Company’s annual results of operations and annual cash flows by approximately $1 million.

Stock Price Risk

The Company is exposed to stock price risk related to its deferred compensation and long-term incentive plans as a portion of the underlying liabilities are tied to the Company’s stock price. The Company had entered into equity total return swap agreements in order to minimize earnings volatility related to fluctuations in the Company’s stock price. The agreements matured in July 2011, cash settlement occured and the agreements were not renewed. See Note 9 of Notes to the Condensed Consolidated Financial Statements for further detail.

See the Company’s Form 10-K for the year ended December 31, 2010 for additional information on the above items.

Item 4. Controls and Procedures

As of the end of the period covered by this report, the Company conducted an evaluation, under the supervision and with the participation of the Company’s chief executive officer and chief financial officer, of the effectiveness of the Company’s disclosure controls and procedures as defined in Rule 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (“Exchange Act”). Based on this evaluation, as of June 30, 2011, the Company’s chief executive officer and chief financial officer concluded that as of the end of such period such disclosure controls and procedures were effective to provide reasonable assurance that they were designed to ensure that information required to be disclosed by the Company in reports it files or submits under the Exchange Act (i) is recorded, processed, summarized and reported within the time period specified in the rules and forms of the Securities and Exchange Commission and (ii) is accumulated and communicated to its management, including its principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

There were no changes in the Company’s internal control over financial reporting (as defined in Rule 13a-15(f) and 15d-15(f) promulgated under the Exchange Act) during the second quarter of 2011 that materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

PART II. OTHER INFORMATION

Item 1A. Risk Factors

Risks Related to Our Potential Acquisition by Lonza Group Ltd.

On July 10, 2011, we entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Lonza Group Ltd., a company organized under the laws of Switzerland (“Lonza”), and LG Acquisition Corp., a Virginia corporation and an indirect wholly owned subsidiary of Lonza (“Merger Sub”), pursuant to which, among other things, Merger Sub has commenced a tender offer for all of the outstanding shares of our common stock, subject to the terms and conditions of the Merger Agreement. In connection with the proposed merger, we are subject to certain risks including, but not limited to, those set forth below.

The announcement and pendency of our acquisition by Lonza could adversely affect our business, financial results and operations.

The announcement and pendency of the proposed acquisition could cause disruptions in and create uncertainty surrounding our business, including affecting our relationships with our customers, vendors and employees, which could have an adverse effect on our business, financial results and operations. In particular, we could lose important personnel as a result of the departure of employees who decide to pursue other opportunities in light of the proposed acquisition. We could potentially lose customers or suppliers, or our customers or suppliers could modify their relationships with us in an adverse manner. In addition, we have diverted, and will continue to divert, significant management resources in an effort to complete the acquisition, which could adversely affect our business and results of operations.

We are also subject to certain restrictions contained in the Merger Agreement on the conduct of our business prior to the consummation of the tender offer. These restrictions could result in our inability to respond effectively, and in a timely manner, to competitive pressures, industry developments and future opportunities or may otherwise harm our business, financial results and operations.

The proposed acquisition by Lonza is subject to the receipt of consents and approvals from government entities that may impose conditions that could have an adverse effect on us or could delay or prevent the completion of the acquisition.

Completion of the acquisition by Lonza is conditioned upon, among other things, the expiration or termination of applicable waiting periods under the United States Hart–Scott–Rodino Antitrust Improvements Act and the receipt of certain other regulatory approvals, each as described in the Merger Agreement. The reviewing authorities may not permit the acquisition at all or may impose restrictions or conditions on the completion of the acquisition. There is no assurance that we will obtain these necessary governmental approvals to complete the acquisition. In addition, any delay in the completion of the acquisition from the failure to obtain such approvals could diminish the anticipated benefits of the acquisition or result in additional transaction costs, loss of revenue or other effects associated with uncertainty about the proposed acquisition.

The failure by Lonza to complete its acquisition of us could adversely affect our business and the market price of our common stock and could result in substantial termination costs.

There is no assurance that completion of the acquisition by Lonza or any other transaction will occur. Consummation of the tender offer is subject to various conditions, including a minimum condition for the valid tender of outstanding shares, consents or approvals of certain governmental authorities and certain other conditions.

The current market price of our common stock may reflect a market assumption that the tender offer and merger will occur. Failure to complete the tender offer and/or merger could adversely affect the share price of our common

38

stock. We will have incurred significant costs, including the diversion of management resources, for which we will have received little or no benefit if the tender offer and merger are not consummated. The Merger Agreement is subject to termination if the Merger is not completed on or before April 10, 2012. In addition, the Merger Agreement contains certain other termination rights for both us and Lonza and further provides that, upon termination of the Merger Agreement under specified circumstances, we may be obligated to pay Lonza a termination fee of $40.0 million. A failed transaction may result in negative publicity and a negative impression of us in the investment community. The occurrence of any of these events individually or in combination could have a material adverse effect on our results of operations and our stock price.
