BASIS OF PRESENTATION AND NEW ACCOUNTING STANDARDS:
BASIS OF PRESENTATION AND NEW ACCOUNTING STANDARDS:	1. BASIS OF PRESENTATION AND NEW ACCOUNTING STANDARDS: *Basis of Presentation— Rockwood Holdings, Inc., which may be referred to as “Rockwood” or the “Company” prepared these unaudited condensed consolidated financial statements following the requirements of the Securities and Exchange Commission and accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim reporting. Under those rules, certain footnotes and other financial information that are normally required for annual financial statements can be condensed or omitted. The Company is responsible for the condensed consolidated financial statements included in this Form 10-Q. These condensed consolidated financial statements include all normal and recurring adjustments necessary for a fair presentation of the financial position as of March 31, 2013 and December 31, 2012, the results of operations and comprehensive income for the three months ended March 31, 2013 and 2012, and cash flows and equity for the three months ended March 31, 2013 and 2012. All intercompany balances and transactions have been eliminated. Material subsequent events are evaluated through the report issuance date and disclosed where applicable. These unaudited condensed consolidated financial statements and the related notes should be read in conjunction with the audited consolidated financial statements for the year ended December 31, 2012 included in the Annual Report on Form 10-K. Revenues, expenses, assets and liabilities can vary during each quarter of the year. Accordingly, the results and trends in these unaudited condensed consolidated financial statements may not be indicative of the full year results. The preparation of financial statements and related disclosures in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and revenue and expenses during the periods reported. These estimates include, among other things, assessing the collectability of accounts receivable, the use and recoverability of inventory, the valuation of deferred tax assets, the measurement of the accrual for uncertain tax benefits, impairment of goodwill as well as property, plant and equipment and other intangible assets, the accrual of environmental and legal reserves and the useful lives of tangible and intangible assets, among others. Actual results could differ from those estimates. Such estimates also include the fair value of assets acquired and liabilities assumed allocated to the purchase price of business combinations consummated. Noncontrolling interest represents the total of the noncontrolling party’s interest in certain investments (principally the Titanium Dioxide Pigments venture and the timber treatment joint venture in the Performance Additives segment) that are consolidated but less than 100% owned. On February 15, 2013, the Company acquired Kemira’s 39% interest in its former Titanium Dioxide Pigments venture for a purchase price of €97.5 million ($130.3 million based on the rate in effect on the date of purchase), subject to certain adjustments. As a result, the Company owns 100% of the Titanium Dioxide Pigments business. Unless otherwise noted, all balance sheet-related items which are denominated in Euros are translated at the March 31, 2013 exchange rate of €1.00 = $1.2819. For the three months ended March 31, 2013 and 2012, the average rate of exchange of the Euro to the U.S. dollar is $1.3199 and $1.3121, respectively. Recently Issued Accounting Standards*: In February 2013, the Financial Accounting Standards Board (“FASB”) issued an Accounting Standards Update (“ASU”) that addressed the reporting of amounts reclassified out of accumulated other comprehensive income, as well as changes within accumulated other comprehensive income. The amendments in this ASU do not change the current requirements for reporting net income or other comprehensive income, but will require companies to present the effects of the line items of net income of significant amounts reclassified out of accumulated other comprehensive income. This ASU is effective for the Company beginning with this Form 10-Q. The required disclosures from this ASU are included in Note 14, “Accumulated Other Comprehensive Income.” In February 2013, the FASB issued an ASU that addressed obligations resulting from joint and several liability arrangements for which the total amount of the obligation is fixed at the reporting date. This ASU provides guidance for the recognition, measurement, and disclosure of obligations resulting from joint and several liability arrangements for which the total amount of the obligation within the scope of this ASU is fixed at the reporting date, except for obligations addressed within existing guidance in U.S. GAAP. The guidance requires an entity to measure those obligations as the sum of the amount the reporting entity agreed to pay on the basis of its arrangement among its co-obligors and any additional amount the reporting entity expects to pay on behalf of its co-obligors. The guidance in this ASU also requires an entity to disclose the nature and amount of the obligation as well as other information about those obligations. This ASU is effective for the Company in its first quarter beginning January 1, 2014 and is not expected to have a material impact on the Company’s financial statements. In March 2013, the FASB issued an ASU that addressed the release of the cumulative translation adjustment (CTA) into net income when a parent either sells a part or all of its investment in a foreign entity or no longer holds a controlling financial interest in a subsidiary or group of assets that is a business. This ASU requires a parent to release any related CTA into net income only if the sale results in the complete or substantially complete liquidation of the foreign entity. This practice is consistent with the Company’s previous accounting policy and will not have an impact on the Company’s financial statements. This ASU is effective for the Company in its first quarter beginning January 1, 2014.
