Financial Statements and Supplementary Data - Note 3, “Segment Information,” for additional financial information regarding our Specialty Chemicals segment.

Surface Treatment

We believe that our Surface Treatment business line is a leading global supplier of surface treatment products and solutions. Surface Treatment’s products are used for a variety of applications and serve the automotive, aerospace and general industrial markets,

6

including steel and metal-working industries. This business line supplies more than 5,000 different products, many of which are based on proprietary formulations and extensive application know-how, to over 50,000 customers and operates in different locations in over 20 countries for production, warehousing or research and development. Surface Treatment operates in the following core end-markets: Automotive Technologies and Components, Cold Forming and Coil, General Industry and Aerospace Technologies.

We develop and supply products and solutions for the chemical pre-treatment of metals and other substrates, some of which are customized for individual customers and applications. Our products and solutions are critical to many areas of the metal processing industry because they protect metals from corrosion, facilitate forming and machining, allow parts to be optimally prepared for the painting process where paint adhesion is critical and ensure good coating adhesion. Other products are used in the cleaning and maintenance of aircraft. As an integrated part of the business, we also offer a full range of customer services, including process control and analysis of chemical baths at clients’ facilities.

Surface Treatment competes in markets characterized by significant barriers to entry, proprietary manufacturing technologies and know-how, demanding product-handling requirements, rigorous product quality and performance standards and specifications and longstanding service-intensive customer relationships. In order to remain competitive, we are focused on developing new products, improving process technologies, expanding our customer base, and broadening our technology capabilities in existing and new markets through internal research and development and bolt-on acquisitions. We have recently expanded our production in India and are building a new plant in Michigan in the United States which is expected to be completed in late 2012. These investments will help us meet the increasing demand for our product portfolio and consolidate our plants in the United States. We also are involved with a number of research and development projects with industrial partners and scientific institutes on a regular basis that help us fulfill our needs for more cost efficient and environmentally compatible technologies. As a result, new products and improved technologies were launched in recent years and more are expected in the future.

The core end-markets that Surface Treatment operates in are as follows:

Automotive Technologies and Components. We provide surface treatment products and solutions for automotive OEMs, including an entire range of products and services for use in the “paint shop” step of car-body and automotive component manufacture. The products and services we provide typically represent a low percentage of total car body production costs, but have high value in terms of corrosion protection and surface quality. Major applications include car-body treatment (zinc-phosphating), paint coagulation and cleaning and pre-treatment of automotive components such as aluminum wheels. Our services typically include intensive process control and chemical management in the customer’s production processes. We are in the process of implementing zinc-phosphate replacements globally, and believe that this represents an attractive growth area in this market. We participate with our joint ventures in China and India for the growth of this segment in the emerging markets.

Cold Forming and Coil. We provide products and services used to facilitate the cold forming of tubes, wire drawing and cold extrusion of metal. We provide products and services used in forming, cleaning and the pre-treating of metal sheets used in the production of steel and aluminum coil.

General Industry. General industry includes the largest number of customers among the Surface Treatment businesses. We offer a range of products and services to a broad range of industrial end-markets that have metal surface treatment applications, including cleaning, activation, conversion coating and final rinsing. Our products include cleaners, iron phosphates, coolants, paint strippers and flocculants. We have also expanded our product range in North America and China, with products in the field of metalworking fluids. Over the last few years, we have introduced a new generation of iron-phosphating products in the U.S. market, which we expect will provide growth in the next few years, and began offering silane or oxsilan-based systems. The markets for General Industry include household appliances manufacturing, can producers, heating, ventilation, aluminum finishing and other diverse end-markets. In addition, we produce specialty products, which are similar to metal surface treatment products, but are used on glass substrates for glass manufacturers, including specialty cleaners, polishing products, cutting oils and cooling lubricants.

Aerospace Technologies. We provide products and services for Aerospace OEMs, airlines and maintenance companies. Aerospace Technologies focuses on four major application areas: cleaning; corrosion protection; maintenance chemicals; and sealants. Cleaning products are used for the interior and exterior cleaning of airplanes and range from daily cleaning to complete aircraft overhaul. Corrosion protection products include waxes used to protect airframes. Maintenance chemicals for aircraft engines and turbines include high performance cleaners and products for non-destructive testing of engines, and aircraft sealants provide high technology sealing solutions for airplanes and are expected to contribute to growth in the next few years. In the last few years, we introduced further variances of low-density sealants in the market place.

Competition

We believe we are a leader in the global metal surface treatment market. Our competitors include Henkel AG & Co. KGaA, Nihon

7

Parkerizing Co., Ltd., PPG Industries, Inc. and Nippon Paint Co., Ltd. Competition in this market is based primarily on customer service, product quality and technological capabilities.

Surface Treatment serves a large customer base that is dependent on the industry served and its specific customer needs. Surface Treatment’s largest customers include Daimler AG, ArcelorMittal, Volkswagen AG, European Aeronautic Defence and Space Company (EADS) N.V and Ford. The composition of the customer base varies widely among product groups and industries served. The Automotive Technologies and Components business division serves approximately 20 customers, primarily global OEMs, and approximately 500 small to large customers in the components markets; the Cold Forming and Coil business division serves approximately 800 mid-size to large customers; the General Industry business division serves approximately 45,000 small to large customers in a broad range of industries worldwide; and the Aerospace Technologies business division serves approximately 4,000 small to large customers worldwide.

Fine Chemicals

Our Fine Chemicals business line consists of our lithium, metal sulfides and special metals product lines. We believe that our Fine Chemicals business line is the leading global producer of lithium products, specialty lithium compounds and chemicals and advanced metal-based specialty chemicals.

Fine Chemicals develops and manufactures a broad range of basic lithium compounds, including lithium carbonate, lithium hydroxide, lithium chloride, and value added lithium specialties and reagents, including butyllithium and lithium aluminum hydride. Lithium is a key component in products and processes used in a variety of applications and industries, which range from lithium batteries, high performance greases, thermoplastic elastomers for car tires, rubber soles and plastic bottles to intermediates in the pharmaceutical industry. In our Fine Chemicals business, we operate our lithium business along the following five business divisions reflecting its core end-markets: (1) Lithium Salts; (2) Special Salts; (3) Butyllithium/Lithium Metal; (4) Battery Products and (5) Lithium Specialties.

In addition to developing and supplying lithium compounds, we provide technical service, including the handling and use of reactive lithium products. We also offer our customers recycling services for lithium containing by-products resulting from synthesis with organolithium products, lithium metal and other reagents. We plan to continue to focus on the development of new products and applications. Currently, we are in the process of developing lithium compounds for several near- to medium-term, new and potentially high growth products for various applications, such as pharmaceuticals and batteries for electric vehicles.

In August 2009, the U.S. Department of Energy awarded $28.4 million in Recovery and Reinvestment Act funds, subject to certain terms and conditions, to our Fine Chemicals business. We are using the funds to expand and upgrade the production of lithium compounds used in lithium-ion batteries for hybrid and electric vehicles at our Silver Peak, Nevada and Kings Mountain, North Carolina facilities. In addition to the funds from this grant, we expect to invest $39.6 million in the project by April 2013. In addition, in September 2009, the German Federal Ministry for the Environment, Nature Conservation and Nuclear Safety awarded €5.7 million to our Fine Chemicals business to set up a pilot plant for the recycling of lithium-ion batteries. Including the funds from this grant, the total investment was €15.5 million.

In February 2012, we announced that we plan to invest $140 million in a new lithium carbonate production plant in Chile. This new investment, along with the expansion in the United States in North Carolina, is expected to increase total annual production capacity to 50,000 metric tons of lithium carbonate by the end of 2013.

Fine Chemicals also develops and manufactures advanced metal-based specialty chemicals along two business divisions based on its principal product groups: (1) Metal Sulfides, which develops and manufactures natural and synthetic metal sulfides used in brake pads, clutch facings and cutting and grinding wheels and (2) Special Metals, which develops and manufactures cesium products for the chemical and pharmaceutical industries and zirconium, barium and titanium products for various pyrotechnical applications, including airbag igniters. In order to further strengthen our competitive position in the metal-based specialty chemicals market, we are focused on the production of new variations of synthetic metal sulfides and new cesium products in the chemicals industry, the pharmaceuticals industry, the defense industry and for use in catalytic applications. We also continuously monitor our customers’ industries for potential new applications for our products. In addition, we expect to expand our business by penetrating growth areas such as India and China.

We expect that demand for synthetic metal sulfides will increase, particularly in Europe, as a result of the continuing substitution for asbestos-based friction linings, the transition from natural sulfides to synthetic sulfides spurred in part by environmental concerns and the transition from drum to disk brakes in Asia and the Americas. We believe further opportunities for growth exist from the use of the

8

newly developed metal sulfides as solid lubricants or as additives for plastics.

Principal Business Divisions

Lithium

Lithium Salts. We develop and manufacture basic lithium compounds, which serve a wide range of industries and applications, and potash. Our products include: (1) lithium carbonate, which is used as a fluxing agent for enamels, glass and ceramic production to lower process temperature in aluminum electrolysis, and as a cement additive for construction applications; (2) lithium hydroxide, which is principally used in high performance greases for automotive and industrial applications; (3) lithium nitrate, which is principally used in the rubber industry; (4) lithium chloride, which is principally used in gas and air treatment; and (5) potash, which we produce as a by-product at our salar in Chile.

Special Salts. To focus more on the specialties within the salts business, we develop and manufacture products including: (1) lithium phosphate which is used as a catalyst for chemical reactions; (2) lithium bromide, which is traditionally used for air conditioning applications and (3) lithium carbonate pharmaceutical grade, which is used in pharmaceutical applications in the United States and Europe.

Butyllithium/Lithium Metal. Butyllithium is used as a polymerization initiator for synthetic rubber and thermoplastic elastomers and as a reagent for the synthesis of active pharmaceutical ingredients and agrochemicals. Lithium metal is used in organic synthesis processes, primarily in the area of steroid chemistry and vitamins. Generally, these products require a high degree of handling, transport and application know-how and customer service due to their high reactivity. We benefit from being a major supplier with butyllithium manufacturing and handling facilities in the United States, Germany, India and Taiwan.

Battery Products. We develop and manufacture lithium products for electronic applications, mainly for the primary (disposable) and secondary (rechargeable) battery industries. Our major product is battery grade lithium carbonate, which is the main component used in the production of thin, lightweight lithium-ion batteries. Lithium-ion-based batteries are used extensively in consumer electronics, such as mobile phones, camcorders, laptops and power tools. Our other products are battery grade lithium hydroxide, which has become more important for the development of high-performance lithium-ion batteries, and battery grade lithium metal, which is used as anode material for primary batteries. We are currently introducing a new generation of conductive lithium salts to the battery market, which we believe has the potential to drive significant growth in the future. We also expect increased demand for lithium products as a result of increased demand for longer-life lithium-based batteries in electric and hybrid electric automobiles.

Lithium Specialties. We develop and manufacture lithium compounds and other products for life science applications, such as special reagents for the synthesis of drug intermediates as well as for the flavor and fragrances industry. The principal products in this business division are lithium aluminum hydride and lithium amides, for which we believe we hold leading market positions. We also produce various other compounds which include lithium metal, grignard reagents and alkoxides. Our research and development team often works closely with research and development departments of pharmaceutical companies, especially in the European market, in order to develop products and solutions tailored for their needs. In addition, broad variations of our lithium specialties are designed to produce liquid crystals for flat screens.

Metal-based Specialty Chemicals

Metal Sulfides. This business division has two major product lines: friction stabilizers and abrasive additives. Friction stabilizers enhance the power and performance of brake pads and clutch facings and primarily serve the automotive supplier industry while abrasive additives are additive compounds. The demand for metal sulfides is driven primarily by the demand in the automotive supplier industry.

Special Metals. We develop and manufacture a unique range of products based on special metal compounds derived from cesium, zirconium, titanium, barium and rubidium. These products are used in highly specialized, technology-driven end-applications such as X-ray diagnostic systems and airbags, and serve various end-markets, such as chemical, pharmaceutical, metallurgical, automotive, electronics and pyrotechnical industries.

Competition

Lithium. We believe the global lithium market consists of three major producers and a number of other small producers mainly from China. We believe that we are the global market leader in the lithium compounds market. While we offer a diverse range of products from raw materials to specialty lithium compounds, FMC Corporation offers mainly specialty lithium compounds, and Sociedad Quimica y Minera de Chile S.A. (“SQM”) offers a more limited product line focused on basic lithium compounds. Competition in this

9

market is based on product quality, reliability of products and customer service.

Metal-based Specialty Chemicals. We believe that in the metal-based specialty chemicals business, Fine Chemicals holds a leading market position in its niche markets. We have a leading position in friction materials and are the only supplier offering a full product range of friction stabilizers and abrasive additives based on metal sulfides. Key competitors include: Dow Corning Corporation, Catalise Industria e Comercio de Metals Ltda and Prince Minerals, Inc. in the Metal Sulfides division and Cabot Corporation and Sigma Aldrich Corporation in the Special Metals division. Competition in the metal-based specialty chemicals markets in which Fine Chemicals competes is based on product quality and product diversity.

Customers

Fine Chemicals serves approximately 1,000 customers worldwide in its lithium business and 700 customers worldwide in its metal-based specialty chemicals products business. Fine Chemicals’ customers of lithium products include Bayer CropScience (a division of Bayer AG), Kraton Performance Polymers Inc., Energizer Holdings, Inc. and Royal DSM N.V.

Performance Additives (21% of 2011 net sales)

Our Performance Additives segment consists of business lines which develop and manufacture a range of specialty chemicals used in industrial and consumer products and processes to enhance performance or create unique characteristics. This segment manufactures and markets products that are based on a focused research and development effort and a strong technology base. Our Performance Additives segment generated net sales of $784.4 million, $726.7 million and $671.5 million for the years ended December 31, 2011, 2010 and 2009, respectively. See Item 8. Financial Statements and Supplementary Data - Note 3, “Segment Information,” for additional financial information regarding our Performance Additives segment.

Color Pigments and Services

Our Color Pigments and Services business line is a global producer of synthetic iron-oxide and other inorganic pigments in a wide range of yellow, red, orange, ultramarine blue, black, manganese violet or blended shades, and serves the construction, paints and coatings, plastics, and specialty application markets with powder, granular and liquid grades. Color Pigments and Services focuses on developing and manufacturing high value-added inorganic pigments. The business also offers a number of unique pigment dispensing systems. Our Color Pigments and Services business line has been driven by product innovation, our brand names and our customer and technical service, including customer-specific color blending.

In December 2011, we announced that we will build an advanced technology production facility in Augusta, Georgia for the synthesis of iron-oxide pigments. This investment will be approximately $115 million and is expected to supply the highest quality color pigments to North American customers, to strengthen customer service and to reduce lead time and improve product development potential. This plant is expected to commence operations in the first half of 2013. Following the completion of this plant, we expect to close our St. Louis, Missouri manufacturing facility and part of our Beltsville, Maryland facility.

Principal Products

Construction Color Pigments and Services. We develop and manufacture principally iron-oxide pigments for manufacturers of construction products for use in the coloring of concrete products, including paving stones, bricks, concrete blocks, roofing tiles, stucco and mortar. Color Pigments and Services’ major U.S. brand is Davis Colors and its other key brands include Granufin/Granumat, Hydrotint, Mix-Ready and Chameleon. Granufin is a unique, dry, microgranulated pigment that combines the flow characteristics of a liquid with the storage and handling advantages of a powder. The Granumat dispensing system offers a variety of configurations and features designed to accommodate the varying requirements and budgets of concrete product manufacturers. Granufin pigments and the Granumat system improve product handling and color consistency for our customers. Our Chameleon system, which works in combination with our liquid pigments, automatically weighs, blends and conveys colors into a ready-mix truck using a standard personal computer and custom-developed Windows-based software.

Paints, Coatings and Colorants. We also develop and manufacture color pigments for the paints, coatings, plastics, paper and rubber end-use markets including our brands Ferroxide, Trans-oxide, Solaplex and Colourplex. We produce a wide variety of pigments for these markets that include synthetic iron-oxides, corrosion inhibitor pigments, complex inorganic color pigments and process natural pigments such as burnt umbers and siennas. The largest application for these products is colorant used in architectural, industrial and special purpose paints and coatings. Color, ease of dispersion and chemical stability are the primary characteristics of our products, which can be used in a wide variety of both solvent and water-borne systems. We believe that a number of Color Pigments and Services’ products are considered industry standards in the markets in which we compete, such as our Mapico yellow and Copperas red pigments for architectural and industrial applications and our heat-stable tans, which can tolerate applications requiring

10

high-temperature processing, such as plastic compounding and roofing granules.

Specialties. Our iron-oxide pigments are also used in a wide variety of specialty applications such as toner for large printers and copiers, security inks used to print bank notes, catalysts for styrene production and cosmetics. Each of these markets requires specialized pigments with unique properties which are often as important as the coloring characteristics. For example, printer toners require specific magnetic properties whereas pigments used in cosmetics require color and purity.

Competition

We believe that there are a significant number of producers of iron-oxide pigments across the globe at both the pigment synthesis and finishing levels with whom we compete. We believe these producers include Lanxess AG, Cathay Pigments Group, Interstar Materials Inc. and Shanghai Yipin Pigments Co., Ltd. as well as other producers in Japan and China. Competition in this segment is based on customer service, product attributes, such as product form and quality, and price. Product quality is critical in the higher end of the business on which Color Pigments and Services focuses, as inconsistent product quality can have an adverse impact on the color consistency of the end-product.

Customers

Color Pigments and Services’ key customers include Akzo Nobel, Oldcastle (CRH plc), The Sherwin-Williams Company, Evonik Degussa GmbH, and W.R. Grace & Co., each of which has been our customer for at least ten years. Color Pigments and Services’ customer base is highly fragmented.

Timber Treatment Chemicals

The Timber Treatment Chemicals business line is a manufacturer of wood protection products primarily in North America and Europe, and we market these products through our joint venture formed in 2007. Wood protection products enhance the performance of wood by increasing its longevity through protection from decay and fungal or insect attack. Our specialty timber chemicals also add water repellency, fire retardancy, mold inhibition and other properties to wood products. Timber Treatment Chemicals’ products include wood protection products based on our alkaline copper quaternary, or ACQ technology, which was awarded the Environmental Protection Agency (“EPA”) Presidential Green Chemistry Challenge Award in 2002; Ecolife, our new non-metallic wood preservative technology; and chromated copper arsenate, or CCA. In 2008, we introduced our newest Ecolife system which utilizes Ecovance, a high-performance non-metallic preservative with enhanced environmental benefits. Introductory commercialization began in 2008, but did not have a material impact in 2011. We expect Ecolife to take advantage of market desire for non-metallic wood protection products and the growth potential in the development and commercialization of the next generation of wood protection products. Other products include Clearwood, our wood protection product for wood windows and doors, as well as a range of specialty additives with fire retardant, water repellent or moldicide properties. Applications for our products include wood protection products used for decking, fencing, playground equipment, garden furniture, house construction materials, utility poles, and other wood constructions.

Titanium Dioxide Pigments (25% of 2011 net sales)

Our Titanium Dioxide Pigments segment operates under the Sachtleben brand name and is a leading producer of high quality chemical products with a unique range of small inorganic particles that add significant value to customers’ products and reduce the cost of customers’ production processes. This segment operates under a venture formed in September 2008 with Kemira Oyj, in which we own 61%. Titanium Dioxide Pigments comprises two business lines: (1) Titanium Dioxide; and (2) Functional Additives. Our Titanium Dioxide Pigments segment generated net sales of $930.4 million, $759.2 million and $666.3 million for the years ended December 31, 2011, 2010 and 2009, respectively. See Item 8. Financial Statements and Supplementary Data - Note 3, “Segment Information,” for additional financial information regarding our Titanium Dioxide Pigments segment and Item 8. Financial Statements and Supplementary Data - Note 4, “Variable Interest Entities,” for further details.

Titanium Dioxide

Our Titanium Dioxide business line is a leading producer of specialty grade titanium dioxide (“TiO2”), serving a wide variety of customers in the synthetic fibers, plastics, paints, packaging inks, coatings, cosmetics, pharmaceuticals and paper industries. TiO2 is a fine white powder that derives its value from its unparalleled whitening strength and opacifying ability, which is commonly referred to as hiding power. Our Titanium Dioxide business line’s principal products include TiO2 in anatase grade, TiO2 in rutile grade and titanium specialties. This business line also provides recycling services for sulfuric waste acid.

There are two ways of producing TiO2: the sulfate process and the chloride process. The chloride process permits production of only rutile TiO2 and is primarily suited for large volume production of standard TiO2 grades. We believe most of the globally installed TiO2 capacity uses the chloride process as opposed to the sulfate process. Unlike the chloride process, the sulfate process is capable of producing both the rutile and anatase grade of TiO2. We employ the sulfate process for TiO2 production and thus, the output from most of the globally installed TiO2 production capacity does not compete with our anatase products.

We believe that we have a competitive advantage in fiber anatase production and special sophisticated anatase applications based on our strong technological capabilities, long-term customer relationships and extensive test runs with regular monitoring of product and process parameters. Although it represents a negligible part of the fiber material cost, TiO2 application know-how and a longstanding application track record of homogeneous anatase crystals, both of which avoid production interruptions and excessive wear or breakdown of our customers’ equipment, are critical to our customers. We intend to focus our rutile business on selected markets and applications and to further develop our titanium specialties business. We expect this segment to benefit from sales of newly introduced nano-particle titanium dioxide pigments that are used to provide ultraviolet light protection for cosmetics, plastics and coatings.

Principal Products

TiO2 in Anatase Grade. We develop and manufacture high quality anatase TiO2 pigments. These pigments are sold primarily to the global synthetic fiber industry, as well as paper, food and pharmaceutical industries. We believe our anatase pigment, sold under the brand name Hombitan, is a leading global-selling TiO2 product for applications in the synthetic fiber industry.

TiO2 in Rutile Grade. We develop and manufacture rutile TiO2 pigments, which are mainly used in special applications such as selected coatings, paints, packaging inks, plastics and laminated paper production processes. In this product area, we are geographically focused on the European market. Rutile-based TiO2 pigments generally possess performance characteristics different from anatase-based pigments. Rutile-based pigments significantly improve the weatherability and durability of polymer products by providing protection against yellowing and preventing embrittlement of the material. Our rutile grades are state of the art products and

13

are used in applications with high technical requirements.

Titanium Specialties. Our titanium specialties products primarily include “nano-particles,” which are exceptionally fine-particled, transparent and easy-to-use pigment formulations that are used across a large and diverse range of applications in small volumes. For example, the specialty grade TiO2 products are used as UV-absorbers in sun protection cosmetics. In addition, the new nano-particles form the basis for innovative wood-protection products and innovative color variations by the paints and coatings industry. Other uses include catalysts, gas cleansing, photocatalysts and intermediates for special ceramics.

Competition

Titanium Dioxide Pigments’ key competitors include: (1) Fuji Titanium Industry Co., Ltd. and Kronos Worldwide, Inc. for anatase-based TiO2; (2) DuPont Titanium Technologies, Cristal Global, Tronox Incorporated, and Huntsman LLC for rutile-based TiO2; and (3) Tayca Corporation, Ishihara Corporation and Evonik Degussa for TiO2 specialties. Competition in the markets in which Titanium Dioxide competes is generally based on technological capabilities, product quality, price in rutile grade and customer service.

Customers

Titanium Dioxide Pigments’ customers include leading manufacturers of paints, such as Akzo Nobel Coatings, Inc., PPG Industries, Inc., BASF Group and E.I. duPont de Nemours and Company; printing inks such as Sun Chemical Corporation, Flint Group and Siegwerk Druckfarben AG; fibers, such as Nan Ya Plastics Corporation and Invista Inc.; plastics, such as Ampacet Corporation and Ineos Group Limited; and paper, such as Munksjo Inc. and Papierfabrik August Koehler AG.

Functional Additives

Our Functional Additives business line is a leading global manufacturer of barium-based and zinc-based inorganic fine white pigments and additives. The main function of these products is to improve brilliance of colors and shine of coatings, improve the mechanical strength of plastic parts and prevent degradation due to exposure to light. Our Functional Additives business line serves diverse end-markets, including the plastics industry, the coatings industry and the pharmaceutical industry.

Principal Products

Barium-based Additives. We produce highly dispersed powders of barium sulfate and are the largest global producer of precipitated synthetic barium sulfates (Blanc Fixe). We provide a unique range of barium-based additives customized for applications in coatings, plastic, colorants, lubricants, PVC stabilizers and thermoplastics, fibers and paper to improve optical, chemical and mechanical properties. We also produce an X-ray-grade barium sulfate used as a contrast agent in medical applications, such as X-rays for the stomach and intestine area.

Zinc-based Additives. We believe we are also a leading producer of pure zinc sulfide pigments, mainly used in glass fiber reinforced plastic parts and coatings and a leading supplier of Lithopone, a white zinc sulfide pigment which is used in plastics and coatings.

Competition

Key competitors for barium-based additives include Solvay S.A., Gruppo Chimico Dalton S.p.A., Sakai Chemical Industry Co., Ltd. and Chinese barium-producers. Key competitors for zinc-based additives include Chinese Lithopone producers. Competition in the functional additives market is primarily based on application know-how, brand recognition, product quality and, to a certain extent, price.

Customers

Functional Additives’ customers include E.I. duPont de Nemours and Company, Ampacet Corporation, BASF Group, Akzo Nobel Coatings, Inc. and A. Schulman, Inc.

Advanced Ceramics (16% of 2011 net sales)

Our Advanced Ceramics segment operates under the CeramTec brand name and is a leading global producer of high-performance advanced ceramics materials and products. Advanced Ceramics serves four principal end-markets: (1) medical; (2) electronics; (3) industrial; and (4) automotive; with strong market positions in various niche markets such as medical products, cutting tools and mechanical applications. Our Advanced Ceramics segment generated net sales of $585.1 million, $515.6 million and $412.2 million

14

for the years ended December 31, 2011, 2010 and 2009, respectively. See Item 8. Financial Statements and Supplementary Data - Note 3, “Segment Information,” for additional financial information regarding our Advanced Ceramics segment.

The global ceramics market comprises products and components based on inorganic, non-metallic, microcrystalline materials that are manufactured at high temperatures. The global ceramics market can be divided into traditional ceramics, such as bricks, tiles and white ware, and high-performance ceramics, which are ceramic materials and products optimized for special purposes. High performance ceramics have superior physical, electrical, chemical or biological properties as compared to traditional ceramics and competing materials, like metals or plastics. High-performance ceramics materials include ceramic powders, ceramic additives, structural ceramics and functional ceramics. Accordingly, they have increasingly replaced plastics and metals as key engineering materials. We compete in the high-performance ceramics segment of the market, offering a wide range of high-performance ceramics products from sealing discs for sanitary fittings to ceramic components for hip joint prostheses. These products serve the market’s needs for materials that are light, strong, corrosion-resistant and capable of performing in high-temperature environments.

We believe that we have achieved success in the Advanced Ceramics segment as a result of our focus on selected segments of the high-performance ceramics market and our close customer relationships. Almost all of Advanced Ceramics’ products are made to order, taking into account specific customer requirements. In many cases, our engineers work in close cooperation with our customers during the design and development phase of new products to ensure highest quality and customer satisfaction. Through its extensive experience, Advanced Ceramics has gained detailed expertise and know-how in its applications areas.

Principal Products

Medical. We currently serve the medical applications market with two product groups - ceramic components for hip joint prostheses, such as ball heads and inserts and ceramic glove formers for high-quality latex gloves. The ceramic components for hip joint prostheses are mainly supplied to orthopedic implant manufacturers in the United States and Europe. Besides their high wear resistance and good friction behavior, high-performance ceramics are biologically inert, making them one of the few materials that are durable and stable enough to withstand the corrosive effects of bodily fluids. As a result, we expect high-performance ceramics will increasingly become more common for medical applications, such as for repair and replacement of hips, knees and other human body parts.

We believe that ceramic-on-ceramic hip implants benefit from additional substitution effects as young people and more active elderly people are better suited to use ceramic implants given their numerous attractive properties. Currently, the penetration rate for ceramic-on-ceramic hip implants in Europe is significantly higher than in North America because the first Food and Drug Administration (“FDA”) approval for ceramic-on-ceramic hip joint prostheses systems was granted in 2003. However, given the relative superior performance and positive early acceptance levels in the United States, we expect the market for ceramic-on-ceramic hip joint prostheses systems to continue to grow significantly in future years. We believe we are well positioned to take advantage of the growing market as we are currently the only manufacturer of ceramic-on-ceramic hip implant components used in FDA-approved hip joint prostheses systems in the United States. Given the difficulties and time involved in obtaining an FDA approval, we believe that we will be the sole supplier of ceramic-on-ceramic hip implant components in the intermediate term. We also enjoy strong relationships with the largest U.S. and European orthopedics implant manufacturers.

Electronics. We develop and manufacture substrates, electrical resistor cores and ceramic tapes as carriers for electronic circuits. Substrates are ceramic plates with electrical, thermal and mechanical properties that serve as carriers in electronic applications. These highly specialized products are used in a wide range of industries, such as the automotive, consumer electronics, aeronautics and telecommunications industries. The demand for these products is driven, in large part, by the activity levels of the semiconductor market as well as a positive substitution effect for ceramic applications. We believe that increasing demand for electronic components will continue to offer significant growth opportunities for high-performance ceramics. As a leading supplier of electronic ceramics materials, we believe we are well positioned to take advantage of these growth opportunities.

Cutting Tools. We develop and manufacture products used in cutting tools, other tools and tooling systems. Ceramic material properties such as high melting points, excellent hardness and good wear resistance make ceramics an excellent high-speed cutting tool material. In addition, the longer life and faster cutting speeds possible with ceramic tools allow customers to save costs by increasing their throughput and reducing the downtimes for replacing their cutting tools. We believe we are a leading supplier of ceramic cutting tools, other tools and tooling systems for high speed processing in the automotive, metalworking and mechanical engineering industries with automotive OEMs and their suppliers being our main customers.

Mechanical Applications and Systems. We also develop and manufacture high performance ceramic components that are used in mechanical applications and systems. Key product groups in mechanical applications include cutting blades, drawing and forming tools, drawing cones and capstans, guide elements, precision parts, pre-forms and friction discs. We primarily supply the general industrial, machinery, metalworking, automotive and textile industries with a large number of products customized to customer

15

requirements. Mechanical systems include products used in the sanitary fittings (ceramic discs and cartridges for faucets) and automotive supplier industries in areas where fluids are pumped, compressed or stirred, such as bushings, face seal rings, pump components and valve shims and discs.

Other products. We also produce products used for applications in certain niche markets, such as electrical/thermal and ceramic metal connections, pre-forms for the casting process of piston engines, mainly for diesel engines, and wear and corrosion protection in industrial plants and armor components used in vehicle protection.

Competition

Advanced Ceramics’ key competitors are Kyocera Corporation, CoorsTek, Inc., The Morgan Crucible Company plc and Ceradyne Inc. However, each of these competitors has either a different geographical focus or product strategy with respect to small niche applications. Competition in the high-performance ceramics market is primarily based on product quality, product specifications and customer service.

Customers

Advanced Ceramics’ key customers include Robert Bosch GmbH, Stryker Corporation, EPCOS AG, DePuy Orthopaedics, Inc. Vishay Intertechnology, Inc., Ideal Standard International BVBA and Zimmer, Inc.

Raw Materials

We purchase raw materials and chemical intermediates from a large number of third parties. Major requirements for our key raw materials and energy are typically satisfied pursuant to contractual agreements and/or medium- or long-term relationships with suppliers. We are not generally dependent on any one supplier for a major part of our raw material requirements, but certain important raw materials are obtained from a few major suppliers. In general, where we have limited sources of raw materials, we have developed contingency plans to minimize the effect of any interruption or reduction in supply, such as sourcing from different facilities, multiple suppliers or utilizing alternative formulations.

We have a broad raw material base with the cost of no single raw material representing more than 3% of our cost of products sold in 2011. Raw materials constituted approximately 48% of our 2011 cost of products sold. The table below lists the ten most significant raw materials in 2011 (in terms of dollars) recorded in cost of products sold and the principal products for which the materials were used.

In our Specialty Chemicals segment, tin is used in the production of metal sulfides and is purchased from five suppliers under annual supply agreements. In addition, antimony sulfide is used in the production of metal sulfides and is purchased from a number of sources. Prices for our tin and antimony sulfide purchases are tied to market conditions.

In our Clay-based Additives business line of our Performance Additives segment, quaternary amine is sourced under a long-term contract, which expires at the end of 2013 and is subject to monthly adjustment for the price of tallow, the base component of quat. In our Timber Treatment Chemicals business, we predominantly source quat under a contract that expires at the end of 2016.

Titanium-bearing slag and ilmenite are the most important raw materials used in the production of specialty grade titanium dioxide in our Titanium Dioxide business line of our Titanium Dioxide Pigments segment. We purchase titanium-bearing slag primarily from two suppliers on a long-term basis and ilmenite from three suppliers on a long-term basis. Both of our titanium-bearing slag suppliers have limited their capacity due to technical reasons. However, we expect that these suppliers will be able to meet our basic demand for 2012, and we will continue to monitor this situation. We expect prices for both slag and ilmenite to be higher in 2012.

In our Timber Treatment Chemicals business, we purchase copper, a commodity, from several sources. Prices for our copper purchases are tied to market conditions. However, we expect the commercialization of our next generation wood protection products to reduce our use of copper beginning in 2012.

16

Historically, we have received iron-oxide from multiple sources and have not experienced any significant supply shortages. Iron-oxide is used in our Color Pigments and Services business within our Performance Additives segment and is purchased from suppliers in China as a supplement to our iron-oxide production.

In our Titanium Dioxide Pigments segment, zinc is used to produce zinc-based pigments and is purchased from a number of suppliers under long-term contracts. There are no long-term zinc purchase contracts in our Specialty Chemicals or Performance Additives segments. In our Specialty Chemicals segment, zinc and zinc oxide are purchased from a few suppliers in Europe and the United States, and we have not experienced any supply shortages. Prices for these purchases are tied to market conditions. In our Performance Additives segment, zinc oxide is used in the production of tan iron-oxide and zinc phosphate and is purchased from multiple suppliers.

Phosphoric acid is used in our Specialty Chemicals segment and is purchased from various global sources. This raw material is used for metal surface treatment chemicals in our Surface Treatment business and wood protection in our Timber Treatment Chemicals business. Currently, there are no long-term purchase contracts for this raw material.

We source the monoethanolamine used in our Timber Treatment Chemicals business from one supplier under a contract that expires at the end of 2012. The contract will automatically renew on an annual basis, subject to termination by either party.

In addition, lithium brine is a primary raw material source for all lithium chemicals and is found in only a small number of locations, including most significantly for us, the Atacama Desert in Chile. We have a long-term contract with the Chilean government to mine lithium brine in the Atacama Desert in Chile, which we believe provides us with a secure long-term access to lithium. We also mine lithium brine at our site in Silver Peak, Nevada.

Temporary shortages of raw materials may occasionally occur and cause temporary price increases. In recent years, these shortages have not resulted in unavailability of raw materials. However, the continuing availability and price of raw materials are affected by unscheduled plant interruptions occurring during periods of high demand, domestic and world market and political conditions, as well as the direct or indirect effect of governmental regulations. During periods of high demand, our raw materials are subject to significant price fluctuations, and, such fluctuations may have an adverse impact on the results of operations of our business. The impact of any future raw material shortages on our business as a whole or in specific geographic regions cannot be accurately predicted.

Intellectual Property

Our business is dependent to a large extent on our intellectual property rights, including patents and other intellectual property, trademarks and trade secrets. We believe that our intellectual property rights play an important role in maintaining our competitive position in a number of the markets we serve. We rely on technological know-how and formulation and application expertise in many of our manufacturing processes in order to develop and maintain our market positions. Where appropriate, we protect our new technology, applications and manufacturing processes by seeking patent protection. We have more than 5,000 patents and patent applications in key strategic markets worldwide, reflecting our commitment to invest in technology and covering many aspects of our products and processes for making those products. We also own and register in multiple jurisdictions numerous trade names and trademarks applicable to our business and products which we believe are important to our business. In addition, we have entered into agreements, pursuant to which we license intellectual property from third parties for use in our business and we license certain intellectual property to third parties. For example, we commercialized Ecolife, our next generation timber treatment preservative from our Timber Treatment Chemicals business, through our joint venture. We also develop intellectual property with third parties as discussed below in “Research and Development.”

Research and Development

We are committed to further investing in our businesses through research and development. Our research and development costs were approximately 2% of our net sales in 2011, which include certain expenses related to modifications and improvements in current products. We allocate our research and development resources selectively based on the needs and requirements of each business line to develop innovative products. Research and development costs are charged to expense, as incurred. Such costs were $59.1 million, $49.3 million and $43.9 million for the years ended December 31, 2011, 2010 and 2009, respectively.

The objective of our research and development effort is to develop innovative chemistries and technologies with applications relevant

17

within targeted key markets. Research and development efforts are generally focused on both process development, which is the stage at which products move from development to manufacturing, and new product development. Each business line, however, also has selected long-term strategic projects with the aim to develop new competencies and technologies. For example, our Fine Chemicals business has set up a pilot plant for the recycling of lithium ion batteries.

Each of our business lines manages its own research and development effort and has separate research and development facilities dedicated to its specific area. However, where technologically feasible, advances and findings are shared between business lines to foster greater cross-fertilization of ideas and applications. In certain cases, we conduct research and development efforts with third parties, including universities, customers and other entities. We endeavor to obtain ownership of or license to, on terms favorable to us, the intellectual property developed with a third party.

Seasonality

There is a seasonal effect on a portion of our net sales due to the end-use of some of our products. Our Color Pigments and Services business line of our Performance Additives segment shows some seasonality related to the construction market which also depends upon weather conditions. As such, the fourth and first quarters have historically been the quarters where we experience the lowest net sales. During these quarters, we typically build inventory for our construction-related businesses, in anticipation of increased sales during the spring and summer months. Thus, these quarters usually have the highest working capital requirements for us. Other than these seasonal trends in certain end-use markets, our overall results of operations tend to show limited seasonal effects.

International Operations

The following table presents net sales based on geographic area (attributed based on seller’s location):

See Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” for further details.

The following table presents the net book value of our long-lived assets located in the regions indicated:

Sales and Marketing

We sell our products and services globally primarily by using our direct sales forces, although we also sell through distributors in certain of our business lines, such as Color Pigments and Services and Clay-based Additives of our Performance Additives segment or by using third party sales representatives. Each of our direct sales forces is responsible for marketing only one of our business lines, and is administered pursuant to policies established by the management of that business line. Within each business line, these direct sales forces are organized based on geographic regions, end-use applications or sub-business divisions within the business line. As of February 1, 2012, our in-house sales forces consisted of approximately 1,600 personnel worldwide.

Our direct sales forces interact with our customers to provide both purchasing advice and technical assistance. In general, our sales

18

forces arrange and coordinate contact between our customers and our research and development or technical personnel to provide quality control and new product solutions. In certain of our businesses, such as the Surface Treatment and Fine Chemicals business lines of our Specialty Chemicals segment, most sales managers have a chemical engineering background with advanced degrees and significant technical experience in applying our products, and they play a critical role in developing client relationships and acquiring new clients. Our close interaction with our customers and tailored solutions have allowed us to develop and maintain strong customer relationships as well as focus our sales efforts on those customers who we believe will provide us with higher profit margins in recognition of our superior products, service and technical support.

Sales in each of our business lines are generally made on a purchase order basis. However, longer-term arrangements have been established with certain key customers.

Our marketing strategy is generally aimed at working directly with customers to gauge the success of our products, evaluating the need for improvements in product and process technology, and identifying opportunities to develop new product solutions for our customers and their end-use markets. We also use media activities, lectures and tradeshows as part of our sales and marketing efforts.

FDA Regulation

Our Advanced Ceramics segment and to a lesser extent, our Specialty Chemicals segment, are subject to regulation by the FDA with respect to certain products we produce, including ceramic ball head and liner components used in hip joint prostheses systems and pharmaceutical intermediates. Foreign, state, local and other authorities also may regulate us and our products. Regulatory agencies have established requirements that apply to the design, manufacture and marketing of pharmaceutical and medical device products. We sell our pharmaceutical intermediates and ceramic-on-ceramic components to other companies that also may be regulated by such authorities.

Premarket Approval. Medical devices also are subject to extensive regulation by the FDA prior to commercial distribution in the United States, including premarket approval (“PMA”), which is required for devices deemed to pose the greatest risk and certain other devices. Our Advanced Ceramics segment currently supplies ceramic ball head and liner components to manufacturers for incorporation into their total hip prostheses systems, which are subject to the FDA’s PMA requirements. In addition, our Advanced Ceramics business or our customers who have obtained PMA approval may be required to obtain FDA approval for changes to the design, manufacturing or labeling of our ceramic ball head and liner components. Also, any other medical devices which our Advanced Ceramics segment seeks to produce in the future, such as knee replacement products, would likely require FDA approval for sales in the United States.

While we are not required to seek FDA approvals for our pharmaceutical intermediates, the customers to whom we supply such products may be subject to FDA approval requirements prior to testing a new drug on humans as well as marketing a new drug for commercial use in the United States. Our customers with FDA approval for a finished drug may also be required to obtain FDA approval of design, manufacturing or labeling changes to the pharmaceutical intermediates used in their finished products.

Compliance Requirements. Once on the market, drug manufacturers and medical device manufacturers are subject to numerous post-market regulations. Finished device manufacturers such as our customers who manufacture hip prostheses systems are subject to the FDA’s Quality System Regulation (“QSR”), which requires quality assurance practices and procedures that address, among other things: management responsibility; audits and training; design controls; purchasing controls; identification and traceability of components; production and process controls; acceptance activities; handling of nonconforming products; the initiation of corrective and preventive actions; labeling and packaging controls; handling, storage and distribution of products and complaint handling and record keeping. The FDA does not directly require component suppliers of finished medical devices to comply with the QSR. However, because our ceramic-on-ceramic ball head and liner components are critical elements of hip joint prostheses systems, our customers may require us to comply with some or all of the QSR. Moreover, the FDA may in the future take the position that the types of components that we supply meet the definition of a finished device and are thus subject to the QSR. Our current contracts with our customers of ceramic-on-ceramic ball head and liner components require us to comply or assist our customers in complying with various FDA regulatory requirements.

The FDA’s inspectional authority extends to component suppliers. Pursuant to this authority, the FDA has the ability to conduct and has conducted inspections at our facilities at which we manufacture our ceramic-on-ceramic ball head and liner components.

If we or our customers violate FDA or other governmental regulatory requirements during either the pre- or post-marketing stages, there may be various adverse consequences. For example, in the United States, the FDA has the authority to impose fines, injunctions, and civil penalties; recall or seize products; impose operating or import restrictions, partial suspension or total shutdown of production; delay its approval or refuse to grant approval of new products; or withdraw the submission of the approved product from the market.

Item 1A. Risk Factors.

You should carefully consider these risk factors in evaluating our business. In addition to the following risks, there may also be risks that we do not yet know of or that we currently think are immaterial that may also affect our business. If any of the following risks occur, our business, results of operations, cash flows or financial condition could be adversely affected.

Leverage—Our available cash and access to additional capital may be limited by our leverage.

We are highly leveraged and have significant debt service obligations. As of December 31, 2011, we had $1,687.7 million of indebtedness outstanding and total equity of $1,658.4 million. This level of indebtedness could have important negative consequences, including:

·                  we may have difficulty obtaining financing in the future for working capital, capital expenditures, acquisitions or other purposes;

·                  we will need to use a substantial portion of our available cash flow to pay interest and principal on our debt, which will reduce the amount of money available to finance our operations and other business activities;

·                  some of our debt, including borrowings under the senior secured credit facilities, have variable rates of interest, which will expose us to the risk of increased interest rates;

20

·                  our debt level increases our vulnerability to general economic downturns and adverse industry conditions;

·                  our debt level could limit our flexibility in planning for, or reacting to, changes in our business and in our industry in general;

·                  our substantial amount of debt and the amount we need to pay to service our debt obligations could place us at a competitive disadvantage compared to our competitors that have less debt; and

·                  our failure to comply with the financial and other restrictive covenants in our debt instruments which, among other things, require us to maintain specified financial ratios and limit our ability to incur debt and sell assets, could result in an event of default that, if not cured or waived, could cause our lenders to terminate commitments under our debt agreements, declare all amounts, including accrued interest, due and payable, and enforce their rights in respect of collateral.

Our cash interest expense for the year ended December 31, 2011 was $91.8 million. After considering interest rate swaps, we had $855.0 million (the majority of which was subject to a Libor floor of 1.00%) of variable rate debt outstanding as of December 31, 2011.

On February 22, 2012, we issued a new tranche of term loan A under our indirect, wholly-owned subsidiary, Rockwood Specialties Group, Inc.’s (“Group” or “Groups”) existing senior secured credit facility in the amount of $350.0 million and expect to use the proceeds and cash on hand to redeem all of our outstanding senior subordinated notes due in 2014 (the “2014 Notes”), consisting of €250.1 million ($324.2 million) in aggregate principal amount of 7.625% euro-denominated notes and $200.0 million in aggregate principal amount of 7.5% dollar-denominated notes, and pay accrued and unpaid interest and applicable redemption premiums. The new term loan bears interest at Libor plus 2.25% (with a 0.25% reduction for achieving a designated credit rating). See Item 8. Financial Statements and Supplementary Data — Note 20, “Subsequent Events” for further details.

After giving effect to the new term loan A and the expected redemption of the outstanding senior subordinated notes, our variable rate debt outstanding would be $1,205.0 million ($845.8 million of which was subject to a Libor floor of 1.00%). A 1% increase in the average interest rate would increase future interest expense by approximately $12.0 million per year. Our debt service for 2012, which represents expected principal payments of our long-term debt and estimated scheduled cash interest payments, is expected to be $313.5 million after giving effect to the new term loan A and expected redemption of the 2014 Notes. See Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Liquidity and Capital Resources — Liquidity — Contractual Obligations” for years beyond 2012.

Additional Borrowings Available—Despite our leverage, we and our subsidiaries may be able to incur more indebtedness. This could further exacerbate the risks described above, including our ability to service our indebtedness.

We and our subsidiaries may be able to incur substantial additional indebtedness in the future. Although our senior secured credit facilities and the indenture governing the 2014 Notes contain restrictions on the incurrence of additional indebtedness, such restrictions are subject to a number of qualifications and exceptions, and under certain circumstances indebtedness incurred in compliance with such restrictions could be substantial. The indenture will no longer impose any restrictions once the 2014 Notes are redeemed. For example, under our credit agreement, the term loans under the senior secured credit facilities may be increased by up to $350.0 million in the aggregate, subject to certain exemptions and provided that Group procures lender commitments for such increase. As of December 31, 2011, the revolving credit facility under the senior secured credit facilities provided for additional borrowings of up to $148.6 million, after giving effect to $31.4 million of letters of credit issued on our behalf. As of December 31, 2011, the Titanium Dioxide Pigments venture facility provided for additional borrowings of up to €12.9 million ($16.7 million) after giving effect to an outstanding bank guarantee of €17.1 million ($22.2 million) related to a defined benefit pension obligation for our Finland Plan. In January 2012, this bank guarantee was increased to €25.5 million ($33.1 million). To the extent new debt is added to our debt levels, the substantial leverage risks described above would increase.

Restrictive Covenants in Our Debt Instruments—Our debt instruments contain a number of restrictive covenants which may limit our ability to finance future operations or capital needs or engage in other business activities that may be in our interest.

Group’s senior secured credit agreement and indenture governing the 2014 Notes and the Titanium Dioxide Pigment’s venture facility agreement impose, and the terms of any future indebtedness may impose, operating and other restrictions on us. Such restrictions will affect, and in many respects limit or prohibit, among other things, our ability to take certain actions. See Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources” section for further details. In addition, Group’s senior secured credit facilities require us and the Titanium Dioxide Pigment’s venture facility requires the venture to achieve certain financial and operating results and maintain compliance with specified financial ratios. Our ability to comply with these ratios may be affected by events beyond our control such as an economic downturn. The restrictions and financial covenants contained in Group’s senior secured credit agreement and indenture governing the 2014 Notes and the Titanium Dioxide Pigment’s venture facility could adversely affect our ability to finance our operations, acquisitions, investments or strategic plans or other capital needs or to engage in other business activities that would be in our interest.

21

A breach of any of these covenants or our inability to comply with the required financial ratios could result in a default under the facilities described above. If an event of default occurs under any of these facilities, which includes an event of default under the indenture governing the 2014 Notes, the lenders could elect to:

·                  declare all borrowings outstanding, together with accrued and unpaid interest, to be immediately due and payable;

·                  require us to apply all of our available cash to repay the borrowings; or

·                  prevent us from making any principal, premium or interest payments;

any of which would result in an event of default. The lenders will also have the right in these circumstances to terminate any commitments they have to provide further financing. If we were unable to repay or otherwise refinance these borrowings when due, our lenders could sell the collateral securing the senior secured credit facilities, which constitutes substantially all of our and our subsidiaries’ assets.

Economic Uncertainty - Downturns in certain industries and general economic conditions could adversely affect our profitability and liquidity.

In the event another economic downturn or recession or disruption in the capital markets occurs, our results of operations, cash flows and financial position could be materially and adversely affected. Under such circumstances, the demand for our products could decrease, which would adversely affect our results of operations. In addition, our products are used in certain industries, such as the automotive and construction industries. Prolonged downturns or bankruptcies in one or more of these industries could severely reduce demand for our products. For example, sales in our Performance Additives business have been adversely impacted by downward trends in commercial and residential construction, housing starts and trends in residential repair and remodeling. Further, a downturn in the automotive industry, particularly in Europe, may adversely affect the results of operations of our Surface Treatment business in our Specialty Chemicals and Advanced Ceramics segments. Moreover, if the value of one or more of our businesses deteriorates, we may be required to record additional impairment charges that could adversely affect our results of operations. If we are unable to successfully anticipate or respond to changing economic conditions, our results of operations and financial position may be materially and adversely affected.

Further, another economic downturn or recession or market disruption in the capital and credit markets may adversely impact the value of our pension plan assets, our statement of operations, our statement of changes in stockholders’ equity and our liquidity. For example, we have several pension plans located in Germany, Finland, the United Kingdom and the United States. Our funding obligations could change significantly based on the investment performance of the pension plan assets and changes in actuarial assumptions for local statutory funding valuations. Any deterioration of the capital markets or returns available in such markets may negatively impact our pension plan assets and increase our funding obligations for one or more of these plans and negatively impact our liquidity. We cannot predict the impact of this or any further market disruption on our pension funding obligations.

Risks Associated with Acquisitions—We may not be able to complete proposed acquisitions nor successfully integrate acquisitions we may undertake in the future.

The process of combining or acquiring businesses with Rockwood involves risks. We may face difficulty integrating the new operations, technologies, products and services of future acquisitions or combinations, and may incur unanticipated expenses related to future acquisitions. The difficulties of combining operations may be magnified by integrating personnel with differing business backgrounds and corporate cultures. Failure to successfully manage and integrate acquisitions with our existing operations could lead to the potential loss of customers of the acquired business, the potential loss of employees who may be vital to the new operations, the potential loss of business opportunities or other adverse consequences that could affect our financial condition and results of operations. Even if integration occurs successfully, failure of any future acquisition or combination to achieve levels of anticipated sales growth, profitability or productivity comparable with those achieved by our existing operations, or otherwise not perform as expected, may adversely impact our financial condition and results of operations. In addition, certain acquisitions may trigger regulations designed to monitor competition and would therefore require regulatory approval. We cannot predict whether such authorities will approve acquisitions we seek to accomplish in the future.

Currency Fluctuations—Because a significant portion of our operations is conducted in foreign currencies, fluctuations in currency exchange rates may adversely impact our financial condition and results of operations and may affect the comparability of our results between financial periods.

Our operations are conducted by subsidiaries in many countries. The results of their operations and financial condition are reported in their functional currency, generally their local currency, and are then translated into U.S. dollars at the applicable exchange rates for

22

inclusion in our consolidated financial statements. The exchange rates between some of these currencies and the dollar in recent years have fluctuated significantly and may continue to do so in the future. A significant portion of our net sales and cost of products sold is denominated in Euros. Approximately 63% of our 2011 net sales were derived from subsidiaries whose local currency is the Euro. This increases the impact of the fluctuation of the Euro against the U.S. dollar.

Furthermore, because a portion of our debt is denominated in Euros, which as of December 31, 2011 equaled €488.2 million ($632.8 million), we are further subject to fluctuation in the exchange rate between the U.S. dollar and the Euro. For example, the U.S. dollar-Euro rate increased from €1.00 = $0.939 on December 31, 2000 to €1.00 = $1.2961 on December 31, 2011.

Being subject to this currency fluctuation may have an adverse effect on the carrying value of our debt. A weakening or strengthening of the Euro against the U.S. dollar by $0.01 would decrease or increase, respectively, by $4.9 million the U.S. dollar equivalent of our total Euro-denominated debt of €488.2 million. In addition, because our consolidated financial statements are reported in U.S. dollars, the translation effect of such fluctuations has in the past significantly impacted, and may in the future, significantly impact the carrying value of our debt. We also incur currency transaction risk whenever we enter into either a purchase or sale transaction using a currency other than the local currency of the transacting entity. We may not be able to effectively manage our currency translation and/or transaction risks, and as a result, volatility in currency exchange rates may have a material adverse effect on the carrying value of our debt and results of operations.

Regulation of Our Raw Materials, Products and Facilities—Our business could be adversely affected by regulation to which our raw materials, products and facilities are subject.

Some of the raw materials we handle, and our products and facilities, are subject to government regulation. These regulations affect the manufacturing processes, handling, uses and applications of our products. In addition, some of our subsidiaries’ products contain raw materials, such as arsenic pentoxide, carbon disulfide, lithium carbonate, tetrahydrofuran, copper, chromic acid, silica, zinc chromate and lead that are deemed hazardous materials in certain situations. The use and handling of these materials is regulated and some of these regulations require product registrations, which also are subject to renewal and potential revocation. For example, in February 2002, the EPA announced a voluntary decision by CCA manufacturers, including our subsidiaries, to amend their registrations for CCA to limit use of CCA-treated lumber in most residential settings, effective December 31, 2003. These regulations may affect our ability to market certain chemicals we produce.

There is also a risk that other key raw materials or one or more of our products may be found to have, or be recharacterized as having, a toxicological or health-related impact on the environment or on our customers or employees. If such a discovery or recharacterization occurs, the relevant materials, chemicals or products, including products of our customers incorporating our materials or chemicals, may be recalled or banned or we may incur increased costs in order to comply with new regulatory requirements. Change in regulations, or their interpretation, may also affect the marketability of certain of our products. We cannot predict how these and other findings from regulatory agencies may affect our cash flows or results of operations.

Manufacturing Hazards—Hazards associated with chemical manufacturing could adversely affect our results of operations.

Due to the nature of our business, we are exposed to the hazards associated with chemical manufacturing and the related storage and transportation of raw materials, products and wastes in our manufacturing facilities or our distribution centers, such as fires, explosions and accidents. These hazards could lead to an interruption or suspension of operations and have an adverse effect on the productivity and profitability of a particular manufacturing facility or on our company as a whole. Other hazards include piping and storage tank leaks and ruptures, mechanical failure, employee exposure to hazardous substances, chemical spills and other discharges or releases of toxic or hazardous substances or gases, inclement weather and natural disasters. These hazards may cause personal injury and loss of life, damage to property and contamination of the environment, which could lead to government fines or work stoppage injunctions and lawsuits by injured persons.

Raw Materials—Fluctuations in costs of our raw materials or our access to supplies of our raw materials could adversely affect our results of operations.

Although no single raw material represented more than 3% of our cost of products sold in 2011, raw material costs generally account for a high percentage of our total costs of products sold. In 2011, raw materials constituted approximately 48% of our cost of products sold. We generally purchase raw materials based on supply agreements linked to market prices and therefore our results of operations are subject to short-term fluctuations in raw materials prices. These fluctuations limit our ability to accurately forecast future raw material costs and hence our profitability.

Many of the raw materials we use are commodities, and the price of each can fluctuate widely for a variety of reasons, including changes in availability, major capacity additions or reductions or significant facility operating problems. Historically, there have been

23

some price increases we have not been able to pass through to our customers. This trend may continue in the future. In addition, titanium-bearing slag used in our Titanium Dioxide Pigments segment is one of our largest raw materials (in terms of dollars) and is sourced primarily from two suppliers. If one of our suppliers is unable to meet its obligations under our present supply agreement or we are unable to enter into new supply arrangements on competitive terms when our existing short-term supply arrangements expire, we may be forced to pay higher prices to obtain these necessary raw materials. In addition, a significant portion of our lithium compounds are processed at a single location of a supplier. Any disruption at this facility could adversely affect our ability to meet market demand for these products, our relationships with our customers and our results of operations. Furthermore, certain of our raw materials, such as cesium and lithium salts, are sourced from countries where political, economic and social conditions may be subject to instability. In addition, one of our raw materials, lithium brine, requires a period of gestation before it can be used to produce lithium compounds. In the event there is an increase in market demand for lithium products, or of unfavorable weather conditions at the lithium ponds, as we experienced in early 2006, we may not be able to respond to such market demand on a timely basis. Any interruption of supply or any price increase of raw materials could result in our inability to meet demand for our products, loss of customer goodwill and higher costs of producing our products.

Energy Costs—Fluctuations in energy costs could have an adverse effect on our results of operations.

Energy purchases in 2011 constituted approximately 8% of Rockwood’s cost of products sold. Fluctuations in the price of energy limit our ability to accurately forecast future energy costs and consequently our profitability. For example, natural gas prices were volatile and increased in 2011 in Europe. Rising energy costs may increase our raw material costs and negatively impact our customers and the demand for our products. These risks will be heightened if our customers or production facilities are in locations experiencing severe energy shortages. For example, our lithium facility in Chile has experienced a shortage of natural gas in the past due to the Argentine government’s decision to ration its supply of natural gas to Chile. If energy prices fluctuate significantly, or we experience severe energy shortages, our business, in particular, our Titanium Dioxide segment where energy costs are more significant, or results of operations may be adversely affected.

Environmental, Health and Safety Regulations—Compliance with extensive environmental, health and safety laws could require material expenditures or changes in our operations.

Our operations are subject to extensive environmental, health and safety laws and regulations at national, international and local levels in numerous jurisdictions. In addition, our production facilities and a number of our distribution centers require operating permits that are subject to renewal. The nature of the chemicals industry exposes us to risks of liability under these laws and regulations due to the production, storage, transportation, disposal and sale of chemicals and materials that can cause contamination or personal injury if released into the environment. In 2011, our capital expenditures for safety, health and environmental matters (“SHE”) were $23.3 million, excluding costs to maintain and repair pollution control equipment. For 2012, we estimate capital expenditures for compliance with SHE laws to be at similar levels.

Compliance with environmental laws generally increases the costs of manufacturing, the cost of registration/approval requirements, the costs of transportation and storage of raw materials and finished products, as well as the costs of the storage and disposal of wastes, and could have a material adverse effect on our results of operations. We may incur substantial costs, including fines, damages, criminal or civil sanctions and remediation costs, or experience interruptions in our operations, for violations arising under these laws or permit requirements. Furthermore, environmental laws are subject to change and have tended to become stricter over time. Such changes in environmental laws or their interpretation, or the enactment of new environmental laws, could result in materially increased capital expenditures and compliance costs. For example, proposed regulation related to greenhouse gases and carbon dioxide emissions, such as the cap and trade requirements, and potential revisions to the Toxic Control Substances Act, could materially and adversely impact our results of operations.

In addition, the discovery of contamination arising from historical industrial operations at some of our former and present properties has exposed us, and in the future may continue to expose us, to cleanup obligations and other damages. For example, soil and groundwater contamination is known to exist at several of our facilities. At December 31, 2011, we had approximately $49.8 million in reserves for estimated environmental liabilities (including reclamation obligations) and estimated the potential range of exposure for such liabilities to be between $49.8 million and $78.9 million.

Environmental Indemnities—We may be subject to environmental indemnity claims relating to properties we have divested.

The discovery of contamination arising from properties that we have divested may expose us to indemnity obligations under the sale agreements with the buyers of such properties or cleanup obligations and other damages under applicable environmental laws. For example, we agreed to indemnify the buyers of our former Electronics business and our plastic compounding business for certain environmental liabilities, respectively, related to such businesses. We may not have adequate insurance coverage or cash flows to make such indemnity payments. Such payments may be costly and may adversely affect our financial condition and results of operations.

24

Product Liability—Due to the nature of our business and products, we may be liable for damages arising out of product liability claims.

The sale of our products involves the risk of product liability claims. For example, some of the chemicals or substances that are used in our businesses, such as arsenic pentoxide, have been alleged to represent potentially significant health and safety concerns. Our subsidiary in our Timber Treatment Chemicals business line has been named as a defendant in personal injury suits in several jurisdictions with retailers and treaters named as other defendants. These suits allege, among other things, product liability claims in connection with the use of timber products treated with CCA, which utilizes arsenic pentoxide as a raw material. For example, a subsidiary in our Advanced Ceramics segment has been named as a defendant in several product liability lawsuits in Europe, which allege various claims against our subsidiary that manufactures ceramic components used in the production of artificial hip joints and our customer has been named in a lawsuit in the United States relating to a broken artificial hip joint.

Also, because many of our products are integrated into our customers’ products, we may be requested to participate in or share in the costs of a product recall conducted by a customer. For example, some of our businesses, including those within our Specialty Chemicals and Advanced Ceramics segments, supply products to customers in the automotive industry. In the event one of these customers conducts a product recall that it believes is related to one of our products, we may be asked to participate in or fund in whole or in part such a recall.

Our customers often require our subsidiaries to represent that our products conform to certain product specifications provided by our customers. Any failure to comply with such specifications could result in claims or legal action against our subsidiaries.

We are unable to estimate our exposure, if any, to the above-mentioned lawsuits at this time. We may be subject to future claims with regard to these suits or others like them and we may not be able to avoid significant product liability exposure. A successful product liability claim or series of claims against us for which we are not otherwise indemnified or insured could materially increase our operating costs or prevent such operating subsidiary from satisfying its financial obligations. For example, for policies renewed on or after November 2002, our insurers excluded CCA from our insurance coverage under our general liability policies. We may not have sufficient cash flow from operations or assets to pay a judgment resulting from a product liability claim or product recall, if any, for which there is no or inadequate insurance coverage. Any such judgment or product recall could materially increase our operating costs or prevent such operating subsidiary from satisfying its financial obligations.

Product Liability—Due to the nature of our business and products, we may be liable for damages arising out of certain indemnity claims.

We may be subject to indemnity claims for product liability lawsuits relating to products we have sold. For example, our Timber Treatment Chemicals business has entered into indemnity agreements with various customers who purchased CCA-based wood protection products. Pursuant to those agreements, one of our subsidiaries agreed to defend and hold harmless those customers for certain causes of action, based on domestic mammalian, and in some cases, human toxicity, caused by our CCA-based wood protection products, subject to certain conditions. Our Timber Treatment Chemicals business has received and may in the future receive claims for indemnity from customers in connection with litigation relating to CCA-based wood protection products and may be required to pay indemnity claims under such agreements to one or more of its customers. Customers of our Advanced Ceramics segment have requested indemnification in certain legal actions related to ceramic components we have supplied to them for use in their hip prosthesis systems. If our subsidiaries are required to pay one or more indemnity claims, insurance may not cover such claims and, if not, our subsidiaries may not have sufficient free cash flow to pay such claims. We are unable to estimate our exposure, if any, to these claims and lawsuits at this time.

In addition, our Specialty Chemicals segment’s subsidiary that formerly manufactured sealants for insulating glass has been named as a defendant in several lawsuits relating to alleged negligent manufacturing of those products. Pursuant to the sale and purchase agreement with respect to the divested “glass” business, this subsidiary may be required to pay indemnity claims, mainly re-glazing costs. Our insurance may not cover such claims and, in such a case, our subsidiary may not have sufficient cash flow to pay these claims. One or more of these claims could adversely affect our financial condition or results of operations.

FDA Regulation—Some of our manufacturing processes and facilities, pharmaceutical customers and medical device customers are subject to regulation by the FDA or similar foreign agencies. These requirements could adversely affect our results of operations.

Regulatory requirements of the FDA are complex. Any failure to comply with them could subject us and/or our customers to fines, injunctions, civil penalties, lawsuits, recall or seizure of products, total or partial suspension of production, denial of government approvals, withdrawal of marketing approvals and criminal prosecution. Any of these actions could adversely impact our net sales,

25

undermine goodwill established with our customers, damage commercial prospects for our products and materially adversely affect our results of operations.

The manufacture and supply of ceramic ball head and liner components for hip joint prostheses systems by our Advanced Ceramics segment may be subject to the FDA’s Quality System Regulation, which imposes current Good Manufacturing Practice requirements on the manufacture of medical devices. Certain lithium compounds manufactured by our Fine Chemicals business line of our Specialty Chemicals segment are also subject to FDA regulation.

In addition, medical device customers of our Advanced Ceramics segment to whom we supply our ceramic ball head and liner components are subject to FDA regulation, including premarket approval of their products and post market compliance requirements. The FDA may take three years or longer to grant premarket approval of our customers’ new products, if at all. Further, our competitors may seek pre-market approval for products that compete with our ceramic hip components. At any time, our customers’ total hip prostheses systems may be withdrawn from the market either voluntarily by our customers or as a result of the FDA’s or a foreign equivalent’s withdrawal of marketing approval or removal of such products for a number of reasons including safety, current Good Manufacturing Practice or Quality System Regulation problems with our products or our customers’ final products. For example, a customer in our Advanced Ceramics segment initiated a voluntary recall in January 2008 of its hip implant system. Any such regulatory action could significantly limit our net sales generated by our Advanced Ceramics segment and may have a material adverse effect on our financial condition and results of operations.

Competition—Our industry is highly competitive. The end-use markets in which we compete are also highly competitive. This competition may adversely affect our results of operations.

We face significant competition from major international producers as well as smaller regional competitors. Our most significant competitors include major chemicals and materials manufacturers and diversified companies, a number of which have revenues and capital resources exceeding ours. In addition, there is increasing competition from market participants in China.

Within the end-use markets in which we compete, competition between products is intense. Substitute products also exist for many of our products. Therefore, we face substantial risk that certain events, such as new product development by our competitors, changing customer needs, production advances for competing products, price changes in raw materials and products, our failure to secure patents or the expiration of patents, could result in declining demand for our products as our customers switch to substitute products or undertake manufacturing of such products on their own. If we are unable to develop, produce or market our products to effectively compete against our competitors, our results of operations may materially suffer.

We believe that our customers are increasingly looking for strong, long-term relationships with a few key suppliers that help them improve product performance, reduce costs, or support new product development. To satisfy these growing customer requirements, our competitors have been consolidating within product lines through mergers and acquisitions. We may also need to invest and spend more on research and development and marketing costs to strengthen existing customer relationships, as well as attract new customers. As a result, our debt level could limit our flexibility to react to these industry trends and our ability to remain competitive.

Product Innovation—If we are not able to continue our technological innovation and successful commercial introduction of new products, our profitability could be adversely affected.

Our industries and the end-use markets into which we sell our products experience periodic technological change and product improvement. Manufacturers periodically introduce new generations of products or require new technological capacity to develop customized products. Our future growth will depend on our ability to gauge the direction of the commercial and technological progress in all key end-use markets and upon our ability to fund and successfully develop, manufacture and market products in such changing end-use markets. We will have to continue to identify, develop, market and in certain cases, secure regulatory approval for innovative products on a timely basis to replace or enhance existing products in order to maintain our profit margins and our competitive position. We may not be successful in developing new products and/or technology, either alone or with third parties, or licensing intellectual property rights from third parties on a commercially competitive basis. Our new products may not be accepted by our customers or may fail to receive regulatory approval. If we fail to keep pace with the evolving technological innovations in our end-use markets on a competitive basis, our business, financial condition and results of operations could be adversely affected.

Dependence on Intellectual Property—If our intellectual property were copied by competitors, or if they were to develop similar intellectual property independently, our results of operations could be negatively affected.

Our success depends to a significant degree upon our ability to protect and preserve our intellectual property rights, which rights we own or use pursuant to licenses granted to us by third parties. The confidentiality and patent assignment agreements we enter into with most of our key employees and third parties to protect the confidentiality, ownership and use of intellectual property may be breached,

26

may not be enforceable, or may provide for joint ownership or ownership by a third party. In addition, we may not have adequate remedies for a breach by the other party, which could adversely affect our intellectual property rights. The use of our intellectual property rights or intellectual property similar to ours by others or our failure to protect such rights could reduce or eliminate any competitive advantage we have developed, adversely affecting our net sales. If we must sue to protect, defend or enforce our intellectual property rights, any suits or proceedings could result in significant costs and diversion of company resources and management attention, and we may not prevail in such action. We are periodically involved in actions related to misappropriation of our intellectual property by former employees. In addition, when our patents expire, competitors or new market entrants may manufacture products substantially similar to our products previously protected by a patent.

We conduct research and development activities with third parties and license certain intellectual property rights from third parties and we plan to continue to do so in the future. For example, in our Timber Treatment Chemicals business, we commercialized Ecolife, our next generation timber treatment preservative from our Timber Treatment Chemicals business, through our joint venture with Rohm and Haas Company (a subsidiary of The Dow Chemical Company). We endeavor to license or otherwise obtain intellectual property rights on terms favorable to us. However, we may not be able to license or otherwise obtain intellectual property rights on such terms or at all. Our inability to license or otherwise obtain such intellectual property rights could have a material adverse effect on our ability to create a competitive advantage and create innovative solutions for our customers, which will adversely affect our net sales and our relationships with our customers.

The steps we take to protect our intellectual property may not provide us with any competitive advantage and may be challenged by third parties. We have been subject to oppositions of our patents and trademarks by third parties before regulatory bodies in certain jurisdictions. Our failure to defend these patents or registered trademarks may limit our ability to protect the intellectual property rights that these applications were intended to cover. In addition, a failure to obtain and defend our trademark registrations may impede our marketing and branding efforts and competitive position. A failure to protect our intellectual property rights could have a material adverse effect on demand for our products and our net sales.

Risk of Intellectual Property Litigation—Our products or processes may infringe the intellectual property rights of others, which may cause us to pay unexpected litigation costs or damages or prevent us from selling our products.

Although it is our intention to avoid infringing or otherwise violating the intellectual property rights of others, our processes and products may infringe or otherwise violate the intellectual property rights of others. We may be subject to legal proceedings and claims, including claims of alleged infringement by us or our licensees of the patents, trademarks and other intellectual property rights of third parties. Intellectual property litigation is expensive and time-consuming, regardless of the merits of any claim, and could divert our management’s attention from operating our businesses. If we were to discover or be notified that our processes or products potentially infringe or otherwise violate the intellectual property rights of others, we may need to obtain licenses from these parties or substantially re-engineer our products and processes in order to avoid infringement. We might not be able to obtain the necessary licenses on acceptable terms, or at all, or be able to re-engineer our products successfully. Moreover, if we are sued for infringement and lose the suit, we could be required to pay substantial damages and/or be enjoined from using or selling the infringing products or technology. Any of the foregoing could cause us to incur significant costs and prevent us from selling our products.

International Operations—As a global business, we are exposed to local business risks in different countries which could have a material adverse effect on our financial condition or results of operations and the value of our common stock.

We have significant operations in many countries, including manufacturing facilities, research and development facilities, sales personnel and customer support operations. Currently, we operate, or others operate on our behalf, facilities in countries such as Brazil, Chile, China, Czech Republic, India, Malaysia, Mexico, Poland, Singapore, South Africa, South Korea, Taiwan and Turkey. Of our total net sales in 2011 of $3,669.3 million, approximately 77% were generated by shipments to customers in countries outside North America. Our operations are affected directly and indirectly by global regulatory, economic and political conditions, including:

·                  new and different legal and regulatory requirements in local jurisdictions;

·                  managing and obtaining support and distribution for local operations;

·                  increased costs of, and availability of, transportation or shipping;

·                  credit risk and financial conditions of local customers and distributors;

·                  potential difficulties in protecting intellectual property;

27

·                  risk of nationalization of private enterprises by foreign governments;

·                  potential imposition of restrictions on investments;

·                  potentially adverse tax consequences, including imposition or increase in withholding and other taxes on remittances, repatriation or other payments by subsidiaries;

·                  capital controls; and

·                  local political, economic and social conditions, including the possibility of hyperinflationary conditions and political instability in certain countries.

In addition, our facilities may be targets of terrorist activities that could result in full or partial disruption of the activities of such facilities. We may not succeed in developing and implementing policies and strategies to counter the foregoing factors effectively in each location where we do business. Our failure to do so could limit our ability to sell products, compete or receive payments for products sold in such locations.

Furthermore, our subsidiaries are subject to rules and regulations related to anti-bribery prohibitions and export controls and economic embargoes, violations of which may carry substantial penalties. For example, export control and economic embargo regulations limit the ability of our subsidiaries to market, sell, distribute or otherwise transfer their products or technology to prohibited countries or persons. Failure to comply with these regulations could subject our subsidiaries to fines, enforcement actions and/or have an adverse effect on our reputation and the value of our common stock. In addition, we are subject to the Dodd-Frank Wall Street Reform and Consumer Protection Act and the Health Care and Education Reconciliation Act of 2010 and the cost of compliance may adversely impact our results of operations.

Retention of Key Personnel—If we lose certain key personnel or are unable to hire additional qualified personnel, we may not be able to execute our business strategy.

Our success depends, in part, upon the continued services of our highly skilled personnel involved in management, research, production, sales and distribution, and, in particular, upon the efforts and abilities of our executive officers and key employees. Although we believe that we are adequately staffed in key positions and that we will be successful in retaining key personnel, we may not be able to retain such personnel on acceptable terms or at all. Furthermore, if we lose the service of any executive officers or key employees, we may not be able to execute our business strategy. We do not have key-person life insurance covering any of our employees.

Relations with Employees—We are subject to stringent labor and employment laws in certain jurisdictions in which we operate, and our relationship with our employees could deteriorate, which could adversely impact our operations.

A majority of our full-time employees are employed outside the United States, particularly in Germany where many of our businesses are located. In certain jurisdictions where we operate, particularly in Germany, labor and employment laws are relatively stringent and, in many cases, grant significant job protection to certain employees, including rights on termination of employment. In addition, in certain countries where we operate, including Germany, our employees are members of unions or are represented by a works council as required by law. We are often required to consult and seek the consent or advice of these unions and/or respective works’ councils. These regulations and laws coupled with the requirement to consult with the relevant unions or works’ councils could significantly limit our flexibility in managing costs and responding to market changes.

Furthermore, with respect to our employees that are subject to collective bargaining arrangements or similar arrangements (approximately one-third of our full-time employees as of February 1, 2012), we may not be able to negotiate labor agreements on satisfactory terms and actions by our employees may disrupt our business. If these workers were to engage in a strike, work stoppage, sabotage or other slowdown, we could experience a significant disruption of our operations and/or higher ongoing labor costs. In addition, if our other employees were to become unionized, we could experience a significant disruption of our operations and/or higher ongoing labor costs.

Tax Liabilities—If GEA Group Aktiengesellschaft (formerly known as mg technologies ag) or Degussa UK Holdings, Ltd. fail to satisfy their contractual obligations, we may be subject to increased tax exposure resulting from pre-acquisition periods.

Under the terms of certain purchase agreements, third party sellers have agreed to substantially indemnify us for tax liabilities pertaining to the pre-acquisition periods. To the extent such companies fail to indemnify or satisfy their obligations, or if any amount

28

is not covered by the terms of the indemnity, earnings could be negatively impacted in future periods through increased tax expense.

Net Loss—We have experienced losses in the past and may experience losses in the future and cannot be certain that our net operating loss carryforwards will continue to be available to offset our tax liability.

We have incurred net losses in the past and we may incur net losses in the future. As of December 31, 2011, we had deferred tax assets of $162.0 million related to worldwide net operating and capital loss carryforwards. Additionally, at December 31, 2011, we had a total valuation allowance of $181.8 million related to net operating loss deferred tax assets and deferred tax assets related to cumulative temporary differences. If our operating performance deteriorates in the future in certain tax jurisdictions, we may be unable to realize these net operating loss carryforwards and we may be required to record an additional valuation allowance.

Anticipated Capital Expenditures—Our required capital expenditures may exceed our estimates.

Our capital expenditures for the year ended December 31, 2011 were $279.7 million, which consisted of expenditures to maintain and improve existing equipment and substantial investments in new equipment. Capital expenditures for 2012 are expected to be above 2011 levels. Future capital expenditures may be significantly higher, depending on the investment requirements of each of our business lines, and may also vary substantially if we are required to undertake actions to compete with new technologies in our industry. We may not have the capital necessary to undertake these capital investments. If we are unable to do so, we may not be able to effectively compete in some of our markets.

Information Security—The security of our information technology systems could be compromised, which could adversely affect our ability to operate.

We depend on information technology to enable us to operate efficiently and interface with customers, as well as maintain financial accuracy and efficiency. Our information technology capabilities are delivered through a combination of internal and outsourced service providers. If we do not allocate and effectively manage the resources necessary to build and sustain the proper technology infrastructure, we could be subject to transaction errors, processing inefficiencies, the loss of customers, business disruptions, or the loss of or damage to our intellectual property through security breach. As with all large systems, our information systems could be penetrated by outside parties intent on extracting information, corrupting information, or disrupting business processes. Our systems have in the past been and likely will in the future be subject to hacking attempts. Unauthorized access could disrupt our business operations and could result in the loss of assets and have a material adverse effect on our business, financial condition, or results of operations.

Our business involves the use, storage, and transmission of information about our employees, vendors, and customers. The protection of such information, as well as our information, is critical to us. The regulatory environment surrounding information security and privacy is increasingly demanding, with the frequent imposition of new and constantly changing requirements. Our subsidiaries also, from time to time, export sensitive customer data and technical information to recipients outside the U.S. Breaches of our security measures or the accidental loss, inadvertent disclosure, or unapproved dissemination of proprietary information or sensitive or confidential data about us or our customers, including the potential loss or disclosure of such information or data as a result of fraud or other forms of deception, could expose us, our customers, or the individuals affected to a risk of loss or misuse of this information, could result in litigation and potential liability for us, damage our reputation, or otherwise harm our business, financial condition or results of operations.

Control—A conflict may arise between our interests and those of KKR.

Affiliates of KKR own approximately 10.3% of our common stock as of December 31, 2011 on an undiluted basis. Although affiliates of KKR no longer hold a majority of our outstanding common stock, they continue to have a significant impact on the vote in any election of directors. In addition, representatives of KKR occupy two of the seven seats on our board of directors. As a result, even though representatives of KKR do not occupy a majority of the seats on our board of directors, affiliates of KKR have substantial influence over our decisions to enter into any corporate transaction and whether any transaction that requires the approval of the stockholders is approved. Additionally, KKR is in the business of making investments in companies and may from time to time acquire and hold interests in businesses that compete directly or indirectly with us. They may also pursue acquisition opportunities that may be complementary to our business, and as a result, those acquisition opportunities may not be available to us.

Item 2. Properties.

We have global operations, serving customers worldwide. To service our customers efficiently, we maintain 81 manufacturing facilities in 23 countries around the world with a strategy of global, regional and local manufacturing to optimize our service offering and minimize production cost to our customers. We believe these facilities are suitable and adequate for their intended use. The table below presents summary information with respect to these facilities:

(1)                This facility is shared by both business divisions of the Specialty Chemicals segment.

(2)                This facility is shared by both the Performance Additives segment and the Titanium Dioxide Pigments segment.

(3)                This facility is shared by the two business divisions of the Titanium Dioxide Pigments segment.

Item 3. Legal Proceedings.

We are involved in legal proceedings from time to time in the ordinary course of our business, including with respect to product liability, intellectual property and environmental matters. In addition, we may be required to make indemnity payments in connection with certain product liability and environmental claims. See Item 1, “Business,” and Item 1A, “Risk Factors,” “Environmental Indemnities—We may be subject to environmental indemnity claims relating to properties we have divested”; “Product Liability— Due to the nature of our business and products, we may be liable for damages arising out of product liability claims”; and “Product Liability—Due to the nature of our business and products, we may be liable for damages arising out of certain indemnity claims.” However, we do not believe that there is any other individual, governmental, legal proceeding or arbitration that is likely to have a material adverse effect on our financial condition, results of operations or cash flows. We cannot predict the outcome of any litigation or the potential for future litigation. See also Item 8. Financial Statements and Supplementary Data - Note 19, “Commitments and Contingencies.”

Lanxess Matter

On January 18, 2010, Lanxess Deutschland GmbH filed suit in the District Court of Satakunta, Finland against Sachtleben Pigments Oy (“Sachtleben”), a subsidiary of the Company’s Titanium Dioxide Pigments venture, claiming breach of contract in connection with Sachtleben’s termination of a supply agreement with plaintiff. In late September 2011, the Court held a hearing on the merits of the case and rendered a judgment in October 2011 against Sachtleben in the amount of €3.2 million ($4.1 million) plus accrued interest and legal fees. The Company appealed the Court’s ruling and the parties entered into a settlement agreement on February 21, 2012. The settlement amount is not materially different than the judgment amount that has been accrued as of December 31, 2011 in the Company’s financial statements.

32

Migratory Bird Matter

In August 2011, the U.S. Department of Justice Environment and Natural Resources Division (“DOJ”), along with the U.S. Fish and Wildlife Service (“FWS”) and the Nevada Department of Wildlife (“NDOW”) commenced an investigation relating to alleged migratory bird deaths at our subsidiary’s Silver Peak, Nevada site in violation of the Migratory Bird Treaty Act of 1918. The Company’s subsidiary is working with the DOJ, FWS and NDOW to address any migratory bird issues. To date, no proceedings have been initiated and no fines have been levied. The Company does not expect the resolution of this matter to have a material impact on its financial condition, results of operations or cash flows.

Inspector General Subpoena

In February 2010, a subsidiary of the Company received a subpoena from the Inspector General of the Department of Defense (“DOD”) seeking information related to a product in the Timber Treatment Chemicals business in the Performance Additives segment. This subsidiary has and will continue to comply with the requests of the DOD to provide the relevant information. The Company cannot predict the likelihood of further legal action or estimate the loss or possible range of loss, if any, in connection with this matter.

Item 4. Mine Safety Disclosures

The information concerning mine safety violations or other regulatory matters required by Section 1503 (a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 104 of Regulation S-K (17 CFR 229.104) is included in Exhibit 95.1 of this annual report.

PART II

Item 5. Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities.

The Company’s common stock is traded on the New York Stock Exchange under the ticker symbol ROC. As of February 17, 2012, there were approximately 49 holders of record of the Company’s common stock.

The following table summarizes the Company’s quarterly common stock information:

Rockwood’s operations are conducted through its subsidiaries and its ability to make payments on any obligations it may have is dependent on the earnings and the distribution of funds from its subsidiaries. As a result, we are dependent upon cash dividends and distributions and other transfers from our subsidiaries to make dividend payments on our common stock. The amounts available to us to pay cash dividends are restricted by our subsidiaries’ debt agreements. Under Group’s senior secured credit facilities and indenture governing the 2014 Notes, Group is permitted to pay dividends or other distributions to us subject to certain limitations and exceptions. Under our senior secured credit agreement, our ability to pay dividends is limited to $600 million, plus additional amounts subject to satisfying certain leverage ratios. Any decision to declare and pay dividends in the future will be made at the discretion of our board of directors and will depend on, among other things, our results of operations, cash requirements, financial condition, contractual restrictions and other factors that our board of directors may deem relevant. See further discussion in liquidity section of Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations.” For the years ended December 31, 2011, 2010 and 2009, the Company did not pay any cash dividends.

There were no repurchases of any of the Company’s common stock by or on behalf of the Company during the fourth quarter of 2011 and no sales of unregistered equity securities by the Company during the fiscal year ended December 31, 2011.
