ROCKWOOD HOLDINGS, INC. AND SUBSIDIARIES

Notes To Condensed Consolidated Financial Statements (Unaudited)

1.  DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

Business Description, Background— Rockwood Holdings, Inc. and Subsidiaries is a global developer, manufacturer and marketer of high value-added specialty chemicals and advanced materials used for industrial and commercial purposes. Unless otherwise indicated, any references to “we,” “our,” “us,” the “Company” or “Rockwood” refer to Rockwood Holdings, Inc. and its consolidated subsidiaries.

Basis of Presentation— The accompanying financial statements of Rockwood are presented on a consolidated basis. All intercompany accounts and transactions have been eliminated in consolidation. In the opinion of management, this information contains all adjustments necessary for a fair presentation of the results for the periods presented.

The interim financial statements included herein are unaudited. The results of operations for the interim periods are not necessarily indicative of the results of operations for the full year. The condensed consolidated financial statements are presented based upon accounting principles generally accepted in the United States of America (“U.S. GAAP”), except that certain information and footnote disclosures, normally included in financial statements prepared in accordance with U.S. GAAP, have been condensed or omitted. The accompanying condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto contained in the Company’s 2009 Form 10-K. In the opinion of management, this information contains all adjustments necessary, consisting of normal and recurring accruals, for a fair presentation of the results for the periods presented.

The Company’s noncontrolling interest represents the total of the noncontrolling party’s interest in certain investments (principally the Titanium Dioxide Pigments venture and the Viance, LLC timber treatment joint venture) that are consolidated but less than 100% owned.

Unless otherwise noted, all balance sheet-related items which are denominated in Euros are converted at the September 30, 2010 exchange rate of €1.00 = $1.3634.

Stock-Based Compensation— Under the 2008 Amended and Restated Stock Purchase and Option Plan of Rockwood Holdings, Inc. and Subsidiaries (the “Plan”) the Company granted stock options, restricted stock and other stock-based awards to the Company’s employees and directors and allowed employees and directors to purchase shares of its common stock. However, the Company no longer issues equity awards under this Plan. In April 2009, the Company adopted the 2009 Stock Incentive Plan (the “New Plan”; together with the Plan, the “Plans”), which has 11,000,000 authorized shares. All equity awards granted after this date will be awarded under the New Plan.

The aggregate compensation cost for stock options, restricted stock units and Board of Director stock grants recorded under the Plans caused income from continuing operations before taxes to decrease by $3.8 million and $1.6 million for the three months ended September 30, 2010 and 2009, respectively, and $9.6 million and $3.1 million for the nine months ended September 30, 2010 and 2009, respectively. The total tax benefit recognized related to stock options was $0.4 million and $0.2 million for the three months ended September 30, 2010 and 2009, respectively, and $0.9 million and $0.3 million for the nine months ended September 30, 2010 and 2009, respectively.

In December 2009, the Company approved an award of 233,657 performance-based restricted stock units to management and key employees which will vest on December 31, 2012 as long as the employee continues to be employed by the Company on this date and upon the achievement of certain performance targets approved by the Company’s compensation committee (“Compensation Committee”). The number of shares of the Company’s common stock ultimately awarded upon vesting is determined based on the achievement of specified performance criteria over the period January 1, 2010 through December 31, 2010. However, the Company did not recognize any compensation cost in 2009 for this issuance because the performance targets that form the basis for vesting of these restricted stock units were not known as of December 31, 2009. These performance targets were set in January 2010, when such performance targets were approved by the Compensation Committee, and as a result, the Company began recording compensation cost on a ratable basis over the vesting period. The grant date fair value of these restricted stock units was $22.00 per stock unit.

All restricted stock units contain a provision in which the units shall immediately vest and become converted into the right to receive a cash payment on the vesting date upon a change in control as defined in such agreement. As the provisions for redemption are outside the control of the Company, the fair value of these units as of September 30, 2010 and December 31, 2009 have been recorded as mezzanine equity (outside of permanent equity) in the condensed consolidated balance sheets.

Recent Accounting Standards—The following represents the impact of recently issued accounting standards:

In June 2009, the FASB issued a statement that requires an enterprise to perform an analysis to determine whether it has a controlling financial interest in a variable interest entity. It requires additional disclosures about involvement with variable interest entities and any significant changes in risk exposure due to that involvement. The Company adopted this statement on January 1, 2010. This statement did not have a material impact on its financial statements. See Note 3, “Variable Interest Entities,” for the disclosure requirements of this statement.

In January 2010, the FASB issued an accounting update that amended guidance and clarified the disclosure requirements about fair market value measurement. This requires a reporting entity to disclose separately the amounts of significant transfers in and out of Level 1 and Level 2 fair value measurements and to describe the reasons for the transfers. In addition, for measurements utilizing significant unobservable inputs, a reporting entity should present separately information about purchases, sales, issuances, and settlements. The Company adopted this update on January 1, 2010. There was no impact upon adoption of this update on the Company’s financial statements. See Note 6, “Fair Value Measurements.”

2.  COMPREHENSIVE INCOME:

Comprehensive income includes net income and the other comprehensive income components which include unrealized gains and losses from foreign currency translation and from certain intercompany transactions that are of a long-term investment nature, pension-related adjustments that are recorded directly into a separate section of equity in the balance sheets and net investment and foreign exchange cash flow hedges. Foreign currency translation amounts and intercompany foreign currency loans are not adjusted for income taxes since they relate to indefinite length investments in non-U.S. subsidiaries.

Comprehensive income is summarized as follows:

3.  VARIABLE INTEREST ENTITIES:

Viance LLC Joint Venture

In January 2007, Chemical Specialties, Inc. (“CSI”), a wholly-owned subsidiary of the Company within the Timber Treatment Chemicals business of the Performance Additives segment, and Rohm and Haas Company (a subsidiary of The Dow Chemical Company) completed the formation of Viance, LLC (“Viance”), a joint venture that provides an extensive range of advanced wood treatment technologies and services to the global wood treatment industry. The Company has concluded that Rockwood is the primary beneficiary of Viance and as such has consolidated the joint venture and reported Rohm and Haas’ interest as noncontrolling interest. This conclusion was made as Rockwood has the obligation to absorb losses of Viance that could potentially be significant to Viance and/or the right to receive benefits from Viance that could potentially be significant to Viance. In addition, CSI has the power to direct the activities of Viance that most significantly impact Viance’s performance as Viance does not own manufacturing facilities. As a result, Viance primarily relies on CSI to provide product and distribution requirements through a supply agreement.

At September 30, 2010 and December 31, 2009, no consolidated assets of the Company were pledged as collateral for any joint venture obligations and the general creditors of the joint venture had no recourse against the Company. The partners have provided $4.0 million of short-term financing to the venture. However, this financing is not subordinated and management believes that such financing could have been readily obtained externally. All intercompany accounts, balances and transactions have been eliminated. Viance’s assets can only be used to settle direct obligations of Viance.

The carrying values of the assets and liabilities of the Viance joint venture included in the condensed consolidated balance sheets are as follows:

Titanium Dioxide Pigments Venture

In September 2008, the Company completed the formation of a Titanium Dioxide Pigments venture with Kemira Oyj (“Kemira”) that focuses on specialty titanium dioxide pigments. The venture includes the combination of the Company’s titanium dioxide pigments and functional additives businesses, including its production facility in Duisburg, Germany, and Kemira’s titanium dioxide business, including Kemira’s titanium dioxide plant in Pori, Finland. The Company has not identified significant variable interests in this venture and accordingly has concluded that this venture does not meet the definition of a variable interest entity (“VIE”). The Company owns 61% of the venture and consolidates it based on the “voting interest” model given its majority ownership and ability to control decision making. Kemira only has certain “protective rights” to limit Rockwood’s control.

In conjunction with this venture, there is a power plant that is legally owned and operated by a Finnish power cooperative (“PVO”). Kemira is a cooperative participant and has an indirect interest in the power plant via ownership of a special share class. The venture utilizes the majority of power supplied. This power plant was determined to be a VIE as the equity holders of the power plant as a group (including Kemira) lack the ability to influence decision making since PVO effectively controls the power plant. It was determined that Rockwood and Kemira jointly form the primary beneficiary of the power plant. The venture has a long-term agreement expiring in August 2018 to purchase steam and electricity (“energy”) from Kemira. Due to the terms of this agreement under which Kemira has the risks and benefits of the majority of the expected life of the power plant, the Company concluded that Kemira is the party most closely associated with the venture and therefore is the primary beneficiary within the related party group. Accordingly, the Company does not consolidate the power plant. The venture purchased $8.6 million and $9.0 million of energy from Kemira in the three months ended September 30, 2010 and 2009, respectively, and $26.9 million and $24.5 million of energy from Kemira in the nine months ended September 30, 2010 and 2009, respectively. Minimum annual payments under the energy agreement are approximately $14.7 million. In connection with this energy arrangement, the venture has approximately $29.2 million (includes a contractual advance of $16.0 million made in 2009) of non-interest bearing notes receivable from Kemira that are due in August 2028. The carrying value of the notes receivable were $5.5 million at September 30, 2010. Interest is imputed at an effective rate of 8.96%. Apart from routine payables to Kemira or PVO in connection with this agreement, no results or balances of the power plant are reflected in the Company’s financial statements.

Other

Rockwood’s Specialty Chemicals segment has several unconsolidated ventures. Two of these ventures do not fit the criteria for classification as a VIE as they are financially self-sustaining, “50/50” ventures both as to control and economics. Other ventures manufacture and market products in China and an additional venture is a service provider at a key manufacturing facility. As the parties share risks and benefits disproportionate to their voting interests, the Company has concluded that these ventures are VIEs. However, the Company has also concluded that it should not consolidate these VIEs as it is not the primary beneficiary. The Company does not have the power and/or ability to direct the activities most affecting venture performance due to governance structure and significant expertise provided and/or functions performed by its venture partners. As of September 30, 2010, Rockwood’s aggregate net investment in these ventures was $12.5 million. This investment is classified as “Other assets” in the condensed consolidated balance sheet and represents Rockwood’s approximate exposure to losses on these investments. Rockwood does not guarantee debt for or have other financial support obligations to these ventures.

4.  SEGMENT INFORMATION:

Rockwood operates in five reportable segments according to the nature and economic characteristics of its products and services as well as the manner in which the information is used internally by the Company’s key decision maker, who is the Company’s Chief Executive Officer. The five segments are: (1) Specialty Chemicals, which consists of the surface treatment and fine chemicals business lines; (2) Performance Additives, which consists of color pigments and services, timber treatment chemicals and clay-based additives; (3) Titanium Dioxide Pigments; (4) Advanced Ceramics; and (5) Specialty Compounds.

Items that cannot be readily attributed to individual segments have been classified as “Corporate and other.” Corporate and other operating loss primarily represents payroll, professional fees and other operating expenses of centralized functions such as treasury, tax, legal, internal audit and consolidation accounting as well as the cost of operating the Company’s central offices (including some costs maintained based on legal or tax considerations). The primary components of Corporate and other loss, in addition to operating loss, are interest expense on external debt (including the amortization of deferred financing costs), foreign exchange losses or gains, and mark-to-market gains or losses on derivatives. Major components within the reconciliation of income from continuing operations before taxes (described more fully below) include systems/organization establishment expenses, interest expense on external debt, foreign exchange losses or gains, and refinancing expenses related to external debt. Corporate and other identifiable assets primarily represent deferred financing costs that have been capitalized in connection with corporate external debt financing, deferred income tax assets and cash balances maintained in accordance with centralized cash management techniques. The Corporate and other classification also includes the results of operations, assets (primarily real estate) and liabilities (including pension and environmental) of legacy businesses formerly belonging to Dynamit Nobel and the wafer reclaim business. The wafer reclaim business works with semiconductor manufacturers to refurbish used test wafers and return them to the manufacturer for reuse in test and process monitor applications.

Summarized financial information for each of the reportable segments is provided in the following table:

(a)                Amounts contained in the “Eliminations” column represent the individual subsidiaries’ retained interest in their cumulative net

cash balance (deposits less withdrawals) included in the corporate centralized cash system and within the identifiable assets of the respective segment. These amounts are eliminated as the corporate centralized cash system is included in the Corporate and other segment’s identifiable assets.

Geographic information regarding net sales based on seller’s location and long-lived assets are described in Note 3, “Segment Information,” in the Company’s 2009 Form 10-K.

On a segment basis, the Company defines Adjusted EBITDA as operating income excluding depreciation and amortization, certain non-cash gains and charges, certain other special gains and charges deemed by senior management to be non-recurring gains and charges and certain items deemed by senior management to have little or no bearing on the day-to-day operating performance of its business segments and reporting units. The adjustments made to operating income directly correlate with the adjustments to net income in calculating Adjusted EBITDA on a consolidated basis pursuant to the Company’s senior secured credit agreement, which reflects management’s interpretations thereof. The indenture governing the senior subordinated notes, due in 2014 (“2014 Notes”), and the facility agreement related to the Titanium Dioxide Pigments venture exclude certain adjustments permitted under the senior credit agreement. Senior management uses Adjusted EBITDA on a segment basis as the primary measure to evaluate the ongoing performance of the Company’s business segments and reporting units. Because the Company views Adjusted EBITDA on a segment basis as an operating performance measure, the Company uses income (loss) from continuing operations before taxes as the most comparable GAAP measure.
