Business Our Company Cabot Microelectronics Corporation (“Cabot Microelec- tronics”, “the Company”, “us”, “we”, or “our”), which was incorporated in the state of Delaware in 1999, is the leading supplier of high-performance polishing slurries and a growing CMP pad supplier used in the manufac- ture of advanced integrated circuit (IC) devices within the semiconductor industry, in a process called chemi- cal mechanical planarization (CMP). CMP is a polishing process used by IC device manufacturers to planarize or flatten many of the multiple layers of material that are deposited upon silicon wafers in the production of advanced ICs. Our products play a critical role in the production of advanced IC devices, thereby enabling our customers to produce smaller, faster and more com- plex IC devices with fewer defects. We currently operate predominantly in one industry segment—the development, manufacture and sale of CMP consumables products. We develop, produce and sell CMP slurries for polishing many of the conducting and insulating materials used in IC devices, and also for polishing the disk substrates and magnetic heads used in hard disk drives. We also develop, manufacture and sell CMP polishing pads, which are used in conjunction with slurries in the CMP process. We also pursue other demanding surface modification applications through our Engineered Surface Finishes (ESF) business where we believe we can leverage our expertise in CMP con- sumables for the semiconductor industry to develop products for demanding polishing applications in other industries. CMP Process Within IC Device Manufacturing IC devices, or “chips”, are components in a wide range of electronic systems for computing, communications, manufacturing and transportation. Individual consumers most frequently encounter IC devices as microproces- sors in their desktop or laptop computers and as mem- ory chips in computers, MP3 players, gaming devices, cell phones and digital cameras, and in mobile Internet devices such as smart phones and tablets. The multi- step manufacturing process for IC devices typically begins with a circular wafer of pure silicon, with the first manufacturing step referred to as a “wafer start”. A large number of identical IC devices, or dies, are manu- factured on each wafer at the same time. The initial steps in the manufacturing process build transistors and other electronic components on the silicon wafer. These are isolated from each other using a layer of insulating material, most often silicon dioxide, to prevent electrical signals from bridging from one transistor to another. These components are then wired together using con- ducting materials such as aluminum or copper in a par- ticular sequence to produce a functional IC device with specific characteristics. When the conducting wiring on one layer of the IC device is completed, another layer of insulating material is added. The process of alternating insulating and conducting layers is repeated until the desired wiring within the IC device is achieved. At the end of the process, the wafer is cut into the individual dies, which are then packaged to form individual chips. Demand for CMP consumable products, including slur- ries and pads, used in the production of IC devices is primarily based on the number of wafer starts by semi- conductor manufacturers and the type and complexity of the IC devices they produce. To enhance the perfor- mance of IC devices, IC device manufacturers have progressively increased the number and density of electronic components and wiring layers in each IC device. This is typically done in conjunction with shrink- ing the key dimensions on an IC device from one tech- nology generation, or “node”, to another. As a result, the number of transistors, wires and the number of discrete wiring layers have increased, increasing the complexity of the IC device and the related demand for CMP consumable products. As semiconductor technol- ogy has advanced and performance requirements of IC devices have increased, the percentage of IC devices that utilize CMP in the manufacturing process has increased steadily over time. We believe that CMP is used in the majority of all IC devices made today, and we expect that the use of CMP will continue to increase in the future. In the CMP polishing process, CMP consumables are used to remove excess material that is deposited during the IC manufacturing process, and to level and smooth the surfaces of the layers of IC devices, via a combina- tion of chemical reactions and mechanical abrasion, leaving minimal residue and defects on the surface, and leaving only the material necessary for circuit integrity. CMP slurries are liquid solutions generally composed of high-purity deionized water and a proprietary mix of chemical additives and engineered abrasives that chem- ically and mechanically interact at an atomic level with the surface material of the IC device. CMP pads are engineered polymeric materials designed to distribute and transport the slurry to the surface of the wafer and 3 distribute it evenly across the wafer. Grooves are cut into the surface of the pad to facilitate distribution of the slurry. The CMP process is performed on a CMP polishing tool. During the CMP process, the wafer is held on a rotating carrier, which is pressed down against a CMP pad. The CMP pad is attached to a rotating pol- ishing table that spins in a circular motion in the oppo- site direction from the rotating wafer carrier. A CMP slurry is continuously applied to the polishing pad to facilitate and enhance the polishing process. Hard disk drive and silicon wafer manufacturers use similar proc- esses to smooth the surface of substrate disks before depositing magnetic media onto the disk. An effective CMP process is achieved through technical optimization of the CMP consumables in conjunction with an appropriately designed CMP process. Prior to introducing new or different CMP slurries or pads into its manufacturing process, an IC device manufacturer generally requires the product to be qualified in its proc- esses through an extensive series of tests and evalua- tions. These qualifications are intended to ensure that the CMP consumable product will function properly within the customers’ overall manufacturing process. These tests and evaluations may require minor changes to the CMP process or the CMP slurry or pad. While this qualification process varies depending on numerous factors, it is generally quite costly and may take six months or longer to complete. IC device manufacturers usually take into account the cost, time required and impact on production when they consider implement- ing or switching to a new CMP slurry or pad. CMP enables IC device manufacturers to produce smaller, faster and more complex IC devices with a greater density of transistors and other electronic com- ponents than is possible without CMP. By enabling IC device manufacturers to make smaller IC devices, CMP also allows them to increase the number of IC devices that fit on a wafer. This increase in the number of IC devices per wafer in turn increases the throughput, or the number of IC devices that can be manufactured in a given time period, and thereby reduces the cost per device. CMP also helps reduce the number of defective or substandard IC devices produced, which increases the device yield. Improvements in throughput and yield reduce an IC device manufacturer’s unit production costs, and reducing costs is one of the highest priorities of a semiconductor manufacturer as the return on its significant investment in manufacturing capacity can be enhanced by lower unit costs. More broadly, sustained growth in the semiconductor industry traditionally has been fueled by enhanced performance and lower unit costs, making IC devices more affordable in an expand- ing range of applications. Precision Polishing Through our ESF business, we are applying our technical expertise in CMP consumables and polishing techniques developed for the semiconductor industry to demand- ing applications in other industries where shaping, enabling and enhancing the performance of surfaces is critical to success, such as for precision optics and elec- tronic substrates, including silicon and silicon-carbide wafers. We have begun selling our CMP consumable products to major silicon wafer manufacturers and we anticipate future growth in this market. Many of the production processes currently used in precision machining and polishing have been based on traditional, labor-intensive techniques, which are being replaced by computer-controlled, deterministic proc- esses. Our wholly-owned subsidiary, QED Technologies International, Inc. (QED), is a leading provider of deter- ministic finishing technology for the precision optics industry. We believe precision optics are pervasive, serving several existing large markets such as semi- conductor equipment, aerospace, defense, security, biomedical and consumer imaging. Our Products CMP Consumables for IC Devices We develop, produce and sell CMP slurries for polishing a wide range of materials that conduct electrical signals, including tungsten, copper, tantalum (commonly referred to as “barrier” which is used in copper wiring applica- tions) and aluminum. Slurries for polishing tungsten are used heavily in the production of advanced memory and logic devices for a multitude of end applications such as computers and servers, MP3 players, gaming devices, cell phones and digital cameras, and in mobile Internet devices such as smart phones and tablets, as well as in mature logic applications such as those used in automo- biles and communication devices. Our most advanced slurries for tungsten polishing are designed to be customized to provide customers greater flexibility, improved performance and a reduced cost of owner- ship. Slurries for polishing copper and barrier materials are used in the production of advanced IC logic devices such as microprocessors for computers, and devices for graphic systems, gaming systems and communication devices, as well as in the production of advanced mem- ory devices. These products include different slurries for polishing the copper film and the thin barrier layer used to separate copper from the adjacent insulating material. Slurries for polishing aluminum are relatively new in the CMP consumables market and are used in the most advanced transistor gate structures currently in production. We offer multiple products for each tech- nology node to enable different integration schemes depending on specific customer needs. 4 We also develop, manufacture and sell slurry products used to polish the dielectric insulating materials that separate conductive layers within logic and memory IC devices. Our core slurry products for these materials are primarily used for high volume applications called Interlayer Dielectric or ILD, and are used in the produc- tion of both older logic devices as well as in mature and advanced memory devices. Our advanced dielectrics products are designed to meet the more stringent and complex performance requirements of lower-volume, more specialized dielectric polishing applications, such as pre-metal dielectric (PMD) and shallow trench isola- tion (STI), at advanced technology nodes. We develop, produce and sell CMP polishing pads, which are consumable materials that work in conjunc- tion with CMP slurries in the CMP polishing process. We believe that CMP polishing pads represent a natural adjacency to our CMP slurry business, since the tech- nologies are closely related and utilize the same techni- cal, sales and support infrastructure. We believe our unique pad material and our continuous pad manufac- turing process enable us to produce a pad with a longer pad life, greater consistency from pad to pad, and enhanced performance, resulting in lower cost of own- ership for our customers. We are producing and selling pads that can be used on a variety of polishing tools, over a range of applications including tungsten, copper and dielectrics, over a range of technology nodes, and on both 200mm and 300mm wafers. Our pad product offerings include our EPIC D100 series of pads and our next generation D200 series. CMP Consumables for the Data Storage Industry We develop and produce CMP slurries for polishing certain materials that are used in the production of rigid disks and magnetic heads used in hard disk drives for computer and other data storage applications, which represent an extension of our core CMP slurry technol- ogy and manufacturing capabilities established for the semiconductor industry. We believe CMP significantly improves the surface finish of these rigid disk coatings, resulting in greater storage capacity of the hard disk drive systems, and also improves the production effi- ciency of manufacturers of hard disk drives by helping increase their throughput and yield. We believe that opportunities for growth may exist within the data storage industry as cloud computing activity grows and the need for data centers utilizing hard disk drive storage increases. Precision Optics Products Through our QED subsidiary, we design and produce precision polishing and metrology systems for advanced optic applications that allow customers to attain near- perfect shape and surface finish on a range of optical components such as mirrors, lenses and prisms. His- torically, advanced optics have been produced using labor-intensive artisanal processes, and variability has been common. QED has automated the polishing proc- ess for advanced optics to enable rapid, deterministic and repeatable surface correction to the most demand- ing levels of precision in dramatically less time than with traditional means. QED’s polishing systems use Magneto-Rheological Finishing (MRF), a proprietary surface figuring and finishing technology, which employs magnetic fluids and sophisticated computer technol- ogy to polish a variety of shapes and materials. QED’s metrology systems use proprietary Subaperture Stitch- ing Interferometry (SSI) technology that captures pre- cise metrology data for large and/or strongly curved optical par ts and proprietar y Aspheric Stitching Interferometry (ASI) technology, which is designed to measure increasingly complex shapes, including non-spherical surfaces, or aspheres. QED’s products also include MRF polishing fluids and MRF polishing components, as well as optical polishing services and polishing support services. Strategy We collaborate closely with our customers to develop and manufacture products that offer innovative and reliable solutions to our customers’ challenges and we strive to consistently and reliably deliver and support these products around the world through what we believe is a robust global infrastructure and supply chain. We continue to focus on the execution of our primary strategy of strengthening and growing our core CMP consumables business within the semiconductor and hard disk drive industries. We are also leveraging our expertise in CMP process and slurry formulation to expand our ESF business in the optics and electronic substrates markets. Strengthening and Growing Our Core CMP Consumables Business We intend to grow our core CMP consumables business by leveraging the capabilities and global infrastructure we have developed as the leader in the CMP slurry industry. We dedicate significant time and resources to new product innovation, and we work closely with our customers to deliver reliable solutions on a global scale that are designed to provide superior quality and lower overall cost of ownership. We believe our strong finan- cial position allows us to fund growth opportunities in our core CMP consumables business through internally developed technologies as well as through potential acquisitions of technologies and businesses. 5 Developing Innovative Solutions: We believe that tech- nology and innovation are vital to success in our CMP consumables business and we devote significant resources to research and development. We need to stay ahead of the rapid technological advances in the electronics industry in order to deliver a broad line of CMP consumables products that meet or exceed our customers’ evolving needs. We have established research and development facilities in the United States, Japan, Taiwan, Singapore, and most recently in South Korea, in order to meet our customers’ technology needs on a global basis. In fiscal 2012, we launched a number of new products within our existing slurry and polishing pad businesses and we expanded sales of some of our newer product offerings crossing multiple applications over a range of technology nodes. Several of our achievements are dis- cussed below: • We secured a number of business wins with both first and second generation pad product platforms. Revenue generated by our polishing pad business in fiscal 2012 increased 8.6% from revenue generated in fiscal 2011. • In South Korea, we qualified new advanced dielectrics products from our new research, development and manufacturing facility that we opened in late fiscal 2011. We have placed strategic emphasis on increas- ing business in Korea as it represents the second largest CMP consumables market in the world, and we successfully increased our fiscal 2012 revenue generated in South Korea by 22% from fiscal 2011. • Within our copper slurry business, we began deliver- ing new copper slurry products in a concentrated form, designed to be diluted by our customers. This reduces transportation costs and assists our custom- ers in lowering their overall cost of ownership. • We secured new business for tungsten slurries for a number of advanced applications. • We also experienced growth in our aluminum slurry products, which are used in advanced High-K metal gate device integration. Close Collaboration With Our Customers: We believe that building close relationships with our customers is key to achieving long-term success in our business. We collaborate with our customers on joint projects to identify and develop new and improved CMP solutions, to integrate our products into their manufacturing proc- esses, and to assist them with supply, warehousing and inventory management. Our customers demand a highly reliable supply source, and we believe we have a competitive advantage because of our ability to timely deliver high-quality products and service from the early stages of product development through the high- volume commercial use of our products. We strategi- cally locate our research facilities and clean rooms, manufacturing operations and the related technical and customer support teams to be responsive to our customers’ needs. We believe our extensive research and development facilities, in close proximity to our customers, provide a competitive advantage. In fiscal 2011, we expanded our facilities at several loca- tions in the Asia Pacific region to further enhance our customer relationships. We completed construction of a new 56,000 square foot research, development and manufacturing facility in Oseong, South Korea. We believe this facility has enhanced our ability to support our customers as South Korea is home to two of the largest manufacturers of memory devices in the world. We also expanded manufacturing capacity in Japan and Singapore to support continued growth in customer demand and to respond more quickly to our customers’ needs in the Asia Pacific region. Robust Global Supply Chain: We believe that product and supply chain quality is critical to success in our busi- ness. Our customers demand continuous improvement in the performance of our products in terms of product quality and consistency. We strive to reduce variation in our products and processes in order to increase quality, productivity and efficiency, and improve the uniformity and consistency of performance of our CMP consum- able products. Our global manufacturing sites are man- aged to ensure we have the people, training and systems needed to support the stringent industry demands for product quality. To support our quality initiative, we practice the concepts of Six Sigma across our Company. Six Sigma is a systematic, data-driven approach and methodology for improving quality by reducing variabil- ity. We believe our Six Sigma initiatives have contributed to significant, sustained improvement in productivity in our operations. We also believe the key supplier awards we received in fiscal 2012 from customers such as Intel and Semiconductor Manufacturing International Cor- poration are evidence of our success in providing our customers with high-quality solutions. We also believe that the depth and breadth of our global supply chain are critical to our success and the success of our customers. We believe this differentiates us from our competitors. We now have five slurry manu- facturing plants worldwide and a global network of suppliers, which we believe position us well to mitigate supply interruptions when unexpected events occur. 6 The major earthquake and resulting tsunami in Japan in March 2011 and the severe flooding in Thailand in late 2011 were prime examples of such unexpected events, in which our global supply chain capabilities enabled us to proactively address the needs of our customers and suppliers to assist them during those difficult times. We believe that our ability to address our customers’ concerns with openness and speed reflects the strength of our customer relationships and their trust in us as a global supplier and business partner. Leveraging Our Expertise into New Markets— Engineered Surface Finishes Business In addition to strengthening and growing our core CMP business, we continue to pursue development of our ESF business. We believe we can leverage our expertise in CMP consumables for the semiconductor industry to develop products for demanding polishing applications in other industries that are synergistic to our CMP con- sumables business. Our primary focus, in this regard, is on opportunities in precision optics and electronic substrates. Our QED subsidiary continues to be the technology leader in deterministic finishing for the precision optics industry. QED’s polishing and metrology technology enables customers to replace manual processes with automated solutions that provide more precise and repeatable results. Another focus of our ESF business is the polishing of electronic substrates, including silicon and silicon-carbide wafers. A key step in the production of these wafers is CMP, which is utilized to ensure that wafers meet the stringent specifications required by IC manufacturers. Industry Trends Semiconductor Industry We believe the semiconductor industry continues to demonstrate several clear trends: the semiconductor business is defined by cyclical growth; there is constant pressure to reduce costs while advancing technology; and, the customer base continues to consolidate. The cyclical nature of the semiconductor industry is closely tied to the global economy as well as to supply and demand within the industry. Following approxi- mately two years of significant growth in the semicon- ductor industry, we began to see some softening of demand within the industry during the second half of fiscal 2011 which we attributed to general uncertainty in the global economy and a modest correction of IC device inventory. This softness in demand continued through the first half of our fiscal 2012. We saw strength- ening in demand during the second half of fiscal 2012, which was led by growth in Korea as well as higher capacity utilization at certain foundries, where compa- nies can outsource some or all of their manufacturing to reduce their fixed costs. Late in our fourth fiscal quarter of 2012, we saw some softening of demand, which appears to be due to decreased demand for DRAM memory, possibly due to softer demand for personal computers (PCs). We believe that semiconductor indus- try demand will grow over the long term based on increased usage of certain types of IC devices in exist- ing applications, as well as an expanding range of new uses of these types of devices. This trend of increased usage of IC devices is most evident in the area of mobile connectivity, including mobile devices such as smart phones and tablets. However, there continues to be uncertainty regarding macroeconomic factors and the outlook for the global economy. Therefore, we believe the near-term outlook for the semiconductor industry is also uncertain. We believe that our Company is well positioned to operate successfully over a range of demand environments as we have successfully navi- gated our business through industry and macroeco- nomic cycles in the past. As the demand for more advanced and lower cost elec- tronic devices grows, there is continued pressure on IC device manufacturers to reduce their costs. Many manufacturers reduce costs by pursuing ever-increasing scale in their operations. Manufacturers also try to reduce costs by migrating to smaller technology nodes, particularly in the production of memory devices. In addition, manufacturers seek ways to increase their production yield while reducing their production costs regardless of the number of units they produce. They look for CMP consumables products with quality and performance attributes that can reduce their overall cost of ownership, pursue ways to use lesser amounts of CMP materials, and also aggressively pursue price reductions for these materials. The pressure on IC device manufacturers to reduce costs has led a number of them to increase their use of foundries, which also leads to increasing scale and lower costs for these foundries. The larger semiconductor manufacturers are generally growing faster than the smaller ones, and we have seen a decline in the number of companies that manufacture semiconductor devices both through mergers and acquisitions as well as through alliances among different companies. The costs to achieve the required scale in manufacturing within the semiconductor industry are 7 increasing, along with the related costs of research and development, and the larger manufacturers generally have greater access to the resources necessary to man- age their businesses. Over time, smaller manufacturers may not be able to compete with the larger manu- facturers on a global basis. Additionally, several of our customers have formed consortia and research and development alliances to better manage the high cost of their development activities, thus reducing the num- ber of design centers we serve. CMP Consumables Industry Demand for CMP consumables is primarily driven by wafer starts, so the CMP consumables industry reflects the cyclicality of the semiconductor industry as well as changes in global economic conditions. Our revenue and net income for fiscal years 2011 and 2012 clearly demonstrated these effects as we saw softening of demand for our products beginning in the second half of fiscal 2011, and this softness continued through the first half of fiscal 2012. We saw significant growth in our revenue and net income during the second half of fiscal 2012 compared to the revenue and net income earned in the first half of fiscal 2012. However, macroeconomic uncertainty continues to cloud the near-term outlook for the semiconductor industry. Over the long term, we anticipate the worldwide market for CMP consumables used by IC device manufacturers will grow as a result of expected long-term growth in wafer starts, an increase in the number of CMP polishing steps required to pro- duce these devices and the introduction of new materi- als in the manufacture of semiconductor devices that will require CMP. We expect the anticipated long-term growth in demand will be somewhat mitigated by continued efficiency improvements in CMP consumable usage as customers seek to reduce their costs. Semiconductor manufactur- ers look for ways to lower the cost of CMP consumables in their production operations, including improvements in technology, diluting slurry or using concentrated slurry products or reducing the slurry flow rate during production to reduce the total amount of slurry used, and extending the polishing time before replacing pads. In addition, we expect to monitor demand trends for PCs, and any related impact on the DRAM memory seg- ment of the semiconductor industry to determine any expected effect on the usage of CMP consumables. As semiconductor technology continues to advance, we believe that CMP technical solutions are becoming more complex, and leading-edge technologies gener- ally require greater customization by customer, tool set and process integration approach. Leading-edge device designs are introducing more materials and processes into next generation chips, and these new materials and processes must be considered in developing CMP solutions. As a result, we generally see customers select- ing suppliers earlier in their development processes and maintaining preferred supplier relationships through production. Therefore, we believe that close collabora- tion with our customers offers the best opportunity for optimal CMP solutions. We also believe that research and development programs continue to be vital to our success as we develop and commercialize innovative, high-performing and more cost-effective CMP solutions. Competition We compete in the CMP consumables industry, which is characterized by rapid advances in technology and demanding product quality and consistency require- ments. We face competition from other CMP consum- ables suppliers, and we also may face competition in the future from significant changes in technology or emerg- ing technologies. However, we believe we are well posi- tioned to continue our leadership in CMP slurries, and to continue to grow our CMP pad business. We believe we have the experience, scale, capabilities and infra- structure that are required for success, and we work closely with the largest customers in the semiconductor industry to meet their growing expectations as a trusted business partner. Our CMP slurry competitors range from small com- panies that compete with a single product and/or in a single geographic region to divisions of global com- panies with multiple lines of CMP products for IC manu- facturers. However, we believe we have more CMP slurry business than any other provider. In our view, we are the only CMP slurry supplier today that serves a broad range of customers by offering and supporting a full line of CMP slurry solutions for all major applications, and that has a proven track record of supplying these products globally in high volumes with the attendant required high level of technical support services. With respect to CMP polishing pads, a division of Dow Chemical has held the leading global position for many years. We believe we are the second largest supplier of polishing pads in the world. A number of other com- panies are attempting to enter this area of the CMP con- sumables business, providing potentially viable product alternatives. We believe our pad materials and our continuous pad manufacturing process have enabled us to produce a pad that provides our customers with a longer pad life, lower defectivity and greater consis- tency than traditional offerings, thus reducing their total pad cost. We believe this has fueled growth in sales of our pad products in recent years. Our QED subsidiary operates in the precision optics industry. There are few direct competitors of QED because its technology is still relatively new and unique. We believe QED’s technology provides a competitive 8 advantage to customers in the precision optics industry, which still relies heavily on traditional artisanal methods of fabrication. Customers, Sales and Marketing Within the semiconductor industry, our customers are primarily producers of logic IC devices or memory IC devices, or they provide IC foundry service. Logic cus- tomers often outsource some or all of the production of their devices to foundries, which provide contract manu- facturing services, in order to avoid the high cost of process development, construction and operation of a fab, or to provide additional capacity when needed. In fiscal 2012, excluding revenue to data storage and ESF customers, approximately 50% of our revenue was from foundry customers, 30% of our revenue was from memory customers and 20% of our revenue was from logic customers. Based upon our own observations and customer survey results, we believe the following factors are the primary influences of our customers’ CMP consumables buying decisions: overall cost of ownership, which represents the cost to purchase, use and maintain a product; prod- uct quality and consistency; product performance and its impact on a customer’s overall yield; engineering support; and delivery/supply assurance. We believe that greater customer sophistication in the CMP process, more demanding integration schemes, additional and unique polishing materials and cost pressures will add further demands on CMP consumables suppliers like us. When these factors are combined with our customers’ desires to gain purchasing leverage and lower their cost of ownership, we believe that only the most reliable, innovative, cost effective, service-driven CMP consum- ables suppliers will thrive. We use a highly collaborative approach to build close relationships with our customers in a variety of areas, and we have customer-focused teams located in each major geographic region. Our sales process begins long before the actual sale of our products and occurs on a number of levels. Due to the long lead times from research and development to product commercializa- tion and sales, we have research teams that collaborate with customers on emerging applications years before the products are required by the market. We also have development teams that interact closely with our cus- tomers, using our research and development facilities and capabilities to design CMP products tailored to their precise needs. Next, our applications engineers work with customers to integrate our products into their manufacturing processes. Finally, as part of our sales process, our logistics and sales personnel provide sup- ply, warehousing and inventory management for our customers. We market our products primarily through direct sales to our customers, although we use distributors in select areas. We believe this strategy provides us an additional means to collaborate with our customers. Our QED subsidiary supports customers in the semi- conductor equipment, aerospace, defense, security, research, biomedical and consumer imaging markets. QED counts among its worldwide customers leading precision optics manufacturers, major semiconductor original equipment manufacturers, research institutions, and the United States government and its contractors. In fiscal 2012, our five largest customers accounted for approximately 48% of our revenue, with TSMC and Samsung accounting for approximately 18% and 13% of our revenue, respectively. For additional information on concentration of customers, refer to Note 2 of “Notes to the Consolidated Financial Statements” included in Item 8 of Part II of this Form 10-K. Research, Development and Technical Support We believe that technology is vital to success in our CMP and ESF businesses, and we plan to continue to devote significant resources to research, development and technical support (R&D), and balance our efforts between the shorter-term market needs and the longer- term investments required of us as a technology leader. We develop and formulate new and enhanced CMP solutions tailored to our customers’ requirements. We work closely with our customers at their facilities to identify their specific technology and manufacturing challenges and to translate these challenges into viable CMP process solutions. Our technology efforts are currently focused on five main areas that span the early conceptual stage of product development involving new materials, proc- esses and designs several years in advance of commer- cialization, to continuous improvement of already commercialized products in daily use in our customers’ manufacturing facilities. These five areas are: • Research related to fundamental CMP technology; • Development and formulation of new and enhanced CMP consumables products, including collaboration on joint development projects with our customers; • Process development to support rapid and effective commercialization of new products; • Technical support of our CMP products in our cus- tomers’ development and manufacturing facilities; and, • Evaluation and development of new polishing and metrology applications outside of the semiconductor industry. 9 Our research in CMP slurries and pads addresses a breadth of complex and interrelated performance crite- ria that relate to the functional performance of the chip, our customers’ manufacturing yields, and their overall cost of ownership. We design slurries and pads that are capable of polishing one or more materials of differing hardness, sometimes at the same time, that make up the semiconductor circuitry. Additionally, our products must achieve the desired surface conditions at high polishing rates, high processing yields and low consumables costs in order to provide acceptable system economics for our customers. As dimensions become smaller and as materials and designs increase in complexity, these challenges require significant investments in R&D. We also commit internal R&D resources to our ESF busi- ness. We believe that application areas we are currently developing, such as precision optics and electronic substrates, represent natural adjacencies to our core CMP business and technology. Products under devel- opment include products used to polish silicon and silicon-carbide wafers to improve the surface quality of these wafers and reduce the customers’ total cost of ownership. We believe that a competitive advantage can be gained through technology, and that our investments in R&D provide us with polishing and metrology capabilities that support the most advanced and challenging cus- tomer technology requirements on a global basis. In fiscal 2012, 2011 and 2010, we incurred approximately $58.6 million, $58.0 million and $51.8 million, respec- tively, in R&D expenses. We believe our Six Sigma initia- tives in our R&D efforts allow us to conduct more research at a lower cost. Investments in property, plant and equipment to support our R&D efforts are capital- ized and depreciated over their useful lives. Our global R&D team includes experts from the semi- conductor industry and scientists from key disciplines required for the development of high-performance CMP consumable products. We operate an R&D facility in Aurora, Illinois, that features a Class 1 clean room and advanced equipment for product development, includ- ing 300mm polishing and metrology capabilities; a technology center in Japan, which includes a Class 1 clean room with 300mm polishing, metrology and slurry development capabilities; an R&D facility in Taiwan within our Epoch subsidiary that includes a clean room with 200mm polishing capability; a new R&D facility in South Korea, that was opened in August 2011, that pro- vides slurry formulation capability; an R&D laboratory in Singapore that provides polishing, metrology and slurry development capabilities for the data storage industry; and a research facility in Rochester, New York to support our QED business. All of these facilities underscore our commitment both to continuing to invest in our technology infrastructure to maintain our technology leadership, and to becoming even more responsive to the needs of our customers. Raw Materials Supply Metal oxides, such as silica and alumina, are significant raw materials we use in many of our CMP slurries. In the interest of supply assurance, our strategy is to secure multiple sources of raw materials and qualify and moni- tor those sources as necessary to ensure our supply of raw materials remains uninterrupted. Also, we have entered into multi-year supply agreements with a num- ber of suppliers for the purchase of raw materials in the interest of supply assurance and to control costs. For additional information regarding these agreements, refer to “Tabular Disclosure of Contractual Obligations”, included in “Management’s Discussion and Analysis of Financial Condition and Results of Operations”, in Item 7 of Part II of this Form 10-K. Intellectual Property Our intellectual property is important to our success and ability to compete. As of October 31, 2012, we had 964 active worldwide patents, of which 226 are U.S. pat- ents, and 581 pending worldwide patent applications, of which 69 are in the U.S. Many of these patents are important to our continued development of new and innovative products for CMP and related processes, as well as for new businesses. Our patents have a range of duration and we do not expect to lose any material pat- ent through expiration within the next four years. We attempt to protect our intellectual property rights through a combination of patent, trademark, copyright and trade secret laws, as well as employee and third party nondisclosure and assignment agreements. We vigorously and proactively pursue parties that attempt to compromise our investments in research and devel- opment by infringing our intellectual property. For example, in 2011, we concluded litigation in the United States against a competitor in which the validity of cer- tain of our CMP slurry patents for tungsten CMP was upheld, although the specific competitive products at issue were found to not infringe the claims at issue. With respect to the same patents, we have been successful before the United States International Trade Commission in prohibiting the importation and sale within the United States of infringing products by another competitor. Most of our intellectual property has been developed internally, but we also may acquire intellectual property from others to enhance our intellectual property portfolio. These enhancements may be via licenses or assignments or we may acquire certain proprietary technology and intellectual property when we make acquisitions. We believe these technology rights continue to enhance our competitive advantage by 10 providing us with future product development opportu- nities and expanding our already substantial intellectual property portfolio. Environmental Matters Our facilities are subject to various environmental laws and regulations, including those relating to air emis- sions, wastewater discharges, the handling and disposal of solid and hazardous wastes, and occupational safety and health. We believe that our facilities are in substan- tial compliance with applicable environmental laws and regulations. By utilizing Six Sigma in our environmental management system process, we believe we have improved operating efficiencies while preserving the environment. Our operations in the United States, Japan, Singapore, Europe and Taiwan are ISO 14001 certified, which requires that we implement and operate according to various procedures that demonstrate our dedication to waste reduction, energy conservation and other environmental concerns. We are committed to maintaining these certifications and are actively pursu- ing ISO 18001 Safety and Health certification for our existing operations. We will also seek to obtain addi- tional certifications, as applicable, in the areas in which we do business. We have incurred, and will continue to incur, capital and operating expenditures and other costs in complying with these laws and regulations in both the United States and other countries. However, we currently do not anticipate that the future costs of environmental compliance will have a material adverse effect on our business, financial condition or results of operations. Employees We believe we have a world-class team of employees who make the Company successful. As of October 31, 2012, we employed 1,042 individuals, including 555 in operations, 261 in research and development and tech- nical, 102 in sales and marketing and 124 in administra- tion. In general, none of our employees are covered by collective bargaining agreements. We have not experi- enced any work stoppages and in general consider our relations with our employees to be good. Financial Information About Geographic Areas We sell our products worldwide. Our geographic cover- age allows us to utilize our business and technical exper- tise from a worldwide workforce, provides stability to our operations and revenue streams to offset geography- specific economic trends, and offers us an opportunity to take advantage of new markets for products. For more financial information about geographic areas, see Note 18 of “Notes to the Consolidated Financial Statements” included in Item 8 of Part II of this Form 10-K. Available Information Our annual reports on Form 10-K, quarterly reports on Form 10-Q, definitive proxy statements on Form 14A, current reports on Form 8-K, and any amendments to those reports are made available free of charge on our Company website, www.cabotcmp.com, as soon as reasonably practicable after such reports are filed with the Securities and Exchange Commission (SEC). Statements of changes in beneficial ownership of our securities on Form 4 by our executive officers and directors are made available on our Company website by the end of the business day following the submission to the SEC of such filings. In addition, the SEC’s website (http://www.sec.gov) contains reports, proxy state- ments, and other information that we file electronically with the SEC. Item 1A. Risk Factors Other than the incurrence of $175.0 million of long-term debt as described below and elsewhere in this Annual Report on Form 10-K, we do not believe there have been any material changes in our risk factors since the filing of our Annual Report on Form 10-K for the fiscal year ended September 30, 2011. However, we may update our risk factors in our SEC filings from time to time for clarification purposes or to include additional information, at management’s discretion, even when there have been no material changes. Risks Relating to Our Business Demand for Our Products Fluctuates and Our Business May Be Adversely Affected by Worldwide Economic and Industry Conditions Our business is affected by economic and industry con- ditions and our revenue is primarily dependent upon semiconductor demand. Semiconductor demand, in turn, is impacted by semiconductor industry cycles, and these cycles can dramatically affect our business. These cycles may be characterized by rapid increases or decreases in product demand, excess or low customer inventories, and rapid changes in prices of IC devices. For example, following approximately two quarters of soft demand in the semiconductor industry during the first half of our fiscal 2012 that followed approximately two years of growth, we again saw industry demand strengthen somewhat during the second half of our fis- cal 2012. By the very end of fiscal 2012, however, we began to see what appears to be some softening of demand. In addition, our business has experienced his- torical seasonal trends as we saw our revenue decrease in the second quarter of fiscal 2012 from the revenue recorded in the first quarter of 2012. Furthermore, com- petitive dynamics within the semiconductor industry may impact our business. Our limited visibility to future 11 customer orders makes it difficult for us to predict industry trends. If the global economy experiences fur- ther weakness and/or the semiconductor industry weak- ens, whether in general or as a result of specific factors, such as current macroeconomic factors, or unpredict- able natural disasters such as the March 2011 natural disasters in Japan, or the November 2011 flooding in Thailand, that have affected the semiconductor, data storage and information technology industries over approximately the last year, we could experience mate- rial adverse impacts on our results of operations and financial condition. Adverse global economic and industry conditions may have other negative effects on our Company. For instance, we may experience negative impacts on cash flows due to the inability of our customers to pay their obligations to us, as evidenced by the $3.7 million bad debt expense we recorded in March 2012, related to a customer bankruptcy filing in Japan in the second quar- ter of fiscal 2012, or our production process may be harmed if our suppliers cannot fulfill their obligations to us. We may also have to reduce the carrying value of goodwill and other intangible assets, which could harm our financial position and results of operations. Some additional factors that affect demand for our products include: the types of products that our cus- tomers may produce, such as logic devices versus mem- ory devices; the various technology nodes at which those products are manufactured; customers’ specific manufacturing process integration schemes; the short order to delivery time for our products; quarter-to- quarter changes in customer order patterns; market share gains and losses; and pricing changes by us and our competitors. We Have a Narrow Product Range and Our Products May Become Obsolete, or Technological Changes May Reduce or Limit Increases in the Consumption of CMP Slurries and Pads Our business is substantially dependent on a single class of products, CMP slurries, which account for the majority of our revenue. Our business in CMP pads is also developing. Our business would suffer if these products became obsolete or if consumption of these products decreased. Our success depends on our abil- ity to keep pace with technological changes and advances in the semiconductor industry and to adapt, improve and customize our products for advanced IC applications in response to evolving customer needs and industry trends. Since its inception, the semicon- ductor industry has experienced rapid technological changes and advances in the design, manufacture, performance and application of IC devices, and our customers continually pursue lower cost of ownership and higher performance of materials consumed in their manufacturing processes, including CMP slurries and pads, as a means to reduce the costs and increase the yield in their manufacturing facilities. We expect these technological changes and advances, and this drive toward lower costs and higher yields, will continue in the future. Potential technology developments in the semiconductor industry, as well as our customers’ efforts to reduce consumption of CMP consumables and to possibly reuse or recycle these products, could render our products less important to the IC device manufac- turing process. A Significant Amount of Our Business Comes from a Limited Number of Large Customers and Our Revenue and Profits Could Decrease Significantly if We Lost One or More of These Customers Our CMP consumables customer base is concentrated among a limited number of large customers. The larger semiconductor manufacturers are generally growing at a faster rate than the smaller ones, and we have seen the number of semiconductor manufacturers decline both through mergers and acquisitions as well as through strategic alliances. Industry analysts predict that this trend will continue, which means the semicon- ductor industry will be comprised of fewer and larger participants if their prediction is correct. One or more of these principal customers could stop buying CMP con- sumables from us or could substantially reduce the quantity of CMP consumables purchased from us. Our principal customers also hold considerable purchasing power, which can impact the pricing and terms of sale of our products. Any deferral or significant reduction in CMP consumables sold to these principal customers, or a significant number of smaller customers, could seri- ously harm our business, financial condition and results of operations. In fiscal 2012, our five largest customers accounted for approximately 48% of our revenue, with Taiwan Semiconductor Manufacturing Company (TSMC) and Samsung accounting for approximately 18% and 13%, respectively, of our revenue. In fiscal year 2011, our five largest customers accounted for approximately 47% of our revenue, with TSMC and Samsung accounting for approximately 17% and 10%, respectively. We Decreased Our Cash Balance Significantly and Incurred a Substantial Amount of Indebtedness in Conjunction With Our Leveraged Recapitalization With a Special Cash Dividend, Which May Adversely Affect Our Cash Flow and Our Ability to Expand Our Business, and We May Be Unable to Comply With Debt Covenants or Secure Additional Financing, if Necessary or Desired, on Terms Acceptable to Our Company As we discussed in our Quarterly Report on Form 10-Q for the fiscal quarter ended March 31, 2012, which was filed with the Securities and Exchange Commission on 12 May 9, 2012, our Board of Directors determined to pursue a new capital management initiative for our Company, which included an increase in the available authorization under our existing share repurchase pro- gram and a leveraged recapitalization with a special cash dividend of approximately $347.1 million in aggre- gate, which we paid in March 2012 by using approxi- mately $172.1 million from our existing cash balance and $175.0 million from a new five-year term loan that is part of the credit facility we finalized in February 2012. The accompanying reduction in our cash balance may reduce our flexibility to operate our business as we have in the past, including limiting our ability to invest in organic growth of our Company, pursue acquisitions, and repurchase our stock. In addition, the new indebt- edness may adversely affect our future cash flow and our ability to pursue our core strategies of strengthen- ing and growing our business, because the incurrence of debt will require us to dedicate a portion of our cash flow from operations to payments on our indebtedness, thereby reducing the availability of cash flows to fund working capital, capital expenditures, share repur- chases, merger and acquisition activities, and other general corporate purposes. The credit facility contains restrictive covenants that impose operating and finan- cial restrictions, including restrictions on our ability to engage in activities and initiatives that we otherwise might decide to pursue. These covenants include, among other things, restrictions on our ability to incur additional debt, engage in certain transactions, and pay additional dividends or make other distributions to our stockholders. The incurrence of debt pursuant to the new credit facility also has required us to incur interest expense charges and other debt related fees that could adversely affect our financial condition and cash flows. Our Business Could Be Seriously Harmed if Our Competitors Develop Superior Slurry Products, Offer Better Pricing Terms or Service, or Obtain Certain Intellectual Property Rights Competition from other CMP slurry manufacturers could seriously harm our business and results of operations. Competition from other providers of CMP consumables could continue to increase, and opportunities exist for other companies to emerge as potential competitors by developing their own CMP consumables products. Increased competition has and may continue to impact the prices we are able to charge for our CMP consum- ables products as well as our overall business. In addi- tion, our competitors could have or obtain intellectual property rights which could restrict our ability to market our existing products and/or to innovate and develop new products. Any Problem or Disruption in Our Supply Chain, Including Supply of Our Most Important Raw Materials, or in Our Ability to Manufacture and Deliver Our Products to Our Customers, Could Adversely Affect Our Results of Operations We depend on our supply chain to enable us to meet the demands of our customers. Our supply chain includes the raw materials we use to manufacture our products, our production operations and the means by which we deliver our products to our customers. Our business could be adversely affected by any problem or interruption in our supply of the key raw materials we use in our CMP slurries and pads, including fumed silica, which we use for certain of our slurries, or any problem or interruption that may occur during production or delivery of our products, such as weather-related prob- lems or natural disasters, like the March 2011 earth- quakes and tsunami in Japan. Our supply chain may also be negatively impacted by unanticipated price increases due to supply restrictions beyond the control of our Company or our raw material suppliers. We believe it would be difficult to promptly secure alternative sources of key raw materials, such as fumed silica, in the event one of our suppliers becomes unable to supply us with sufficient quantities of raw mate- rials that meet the quality and technical specifications required by us and our customers. In addition, contrac- tual amendments to the existing agreements with, or non-performance by, our suppliers, including any signifi- cant financial distress our suppliers may suffer, could adversely affect us. For instance, Cabot Corporation continues to be our primary supplier of particular amounts and types of fumed silica, and our current fumed silica supply agreement with Cabot Corporation expires December 31, 2012. We are in the process of working with Cabot Corporation to negotiate the terms of a new agreement for continued supply of fumed silica; however, at present such negotiations are not complete and any final terms could have an adverse effect on our business. Also, if we change the supplier or type of key raw materials we use to make our CMP slurries or pads, or are required to purchase them from a different manufacturer or manufacturing facility or otherwise modify our products, in certain circumstances our customers might have to requalify our CMP slurries and pads for their manufacturing processes and prod- ucts. The requalification process could take a signifi- cant amount of time and expense to complete and could motivate our customers to consider purchasing products from our competitors, possibly interrupting or reducing our sales of CMP consumables to these customers. 13 We Are Subject to Risks Associated With Our Foreign Operations We currently have operations and a large customer base outside of the United States. Approximately 87%, 86% and 86% of our revenue was generated by sales to cus- tomers outside of the United States for the fiscal 2012, 2011 and 2010, respectively. We encounter risks in doing business in certain foreign countries, including, but not limited to, adverse changes in economic and political conditions, fluctuation in exchange rates, compliance with a variety of foreign laws and regulations, as well as difficulty in enforcing business and customer contracts and agreements, including protection of intellectual property rights. We also encounter risks that we may not be able to repatriate earnings from certain of our for- eign operations, derive anticipated tax benefits of our foreign operations or recover the investments made in our foreign operations. Because We Rely Heavily on Our Intellectual Property, Our Failure to Adequately Obtain or Protect It Could Seriously Harm Our Business Protection of intellectual property is particularly impor- tant in our industry because we develop complex tech- nical formulas for CMP products that are proprietary in nature and differentiate our products from those of our competitors. Our intellectual property is important to our success and ability to compete. We attempt to protect our intellectual property rights through a com- bination of patent, trademark, copyright and trade secret laws, as well as employee and third-party nondis- closure and assignment agreements. Due to our inter- national operations, we pursue protection in different jurisdictions, which may provide varying degrees of pro- tection, and we cannot provide assurance that we can obtain adequate protection in each such jurisdiction. Our failure to obtain or maintain adequate protection of our intellectual property rights for any reason, including through the patent prosecution process or in the event of litigation related to such intellectual property, such as the former litigation between us and a competitor, in which the validity of all of our patents at issue in the matter was upheld as further described in Part 1, Item 3 under the heading “Legal Proceedings”, could seriously harm our business. In addition, the costs of obtaining or protecting our intellectual property could negatively affect our operating results. We May Pursue Acquisitions of, Investments in, and Strategic Alliances With Other Entities, Which Could Disrupt Our Operations and Harm Our Operating Results if They Are Unsuccessful We expect to continue to make investments in tech- nologies, assets and companies, either through acqui- sitions, investments or alliances, in order to supplement our internal growth and development efforts. Acqui- sitions and investments involve numerous risks, includ- ing the following: difficulties and risks in integrating the operations, technologies, products and personnel of acquired companies; diversion of management’s atten- tion from normal daily operations of the business; increased risk associated with foreign operations; poten- tial difficulties and risks in entering markets in which we have limited or no direct prior experience and where competitors in such markets have stronger market posi- tions; potential difficulties in operating new businesses with different business models; potential difficulties with regulatory or contract compliance in areas in which we have limited experience; initial dependence on unfamil- iar supply chains or relatively small supply partners; insufficient revenues to offset increased expenses asso- ciated with acquisitions; potential loss of key employees of the acquired companies; or inability to effectively cooperate and collaborate with our alliance partners. Further, we may never realize the perceived or antici- pated benefits of a business combination, asset acquisi- tion or investments in other entities. Acquisitions by us could have negative effects on our results of operations, in areas such as contingent liabilities, gross profit mar- gins, amortization charges related to intangible assets and other effects of accounting for the purchases of other business entities. Investments in and acquisitions of technology-related companies or assets are inher- ently risky because these businesses or assets may never develop, and we may incur losses related to these investments. In addition, we may be required to impair the carrying value of these acquisitions or investments to reflect other than temporary declines in their value, which could harm our business and results of operations. Because We Have Limited Experience in Business Areas Outside of CMP Slurries, Expansion of Our Business into New Products and Applications May Not Be Successful An element of our strategy has been to leverage our current customer relationships and technological exper- tise to expand our CMP business from CMP slurries into other areas, such as CMP polishing pads. Additionally, in our Engineered Surface Finishes business, we are pursu- ing other surface modification applications. Expanding our business into new product areas could involve tech- nologies, production processes and business models in which we have limited experience, and we may not be able to develop and produce products or provide serv- ices that satisfy customers’ needs or we may be unable to keep pace with technological or other developments. Also, our competitors may have or obtain intellectual property rights that could restrict our ability to market our existing products and/or to innovate and develop new products. 14 We May Not Be Able to Monetize Our Investments in Auction Rate Securities in the Short Term and We Could Experience a Decline in Their Market Value, Which Could Adversely Affect Our Financial Results We owned auction rate securities (ARS) with an esti- mated fair value of $8.0 million ($8.2 million par value) at September 30, 2012, which were classified as other long- term assets on our Consolidated Balance Sheet. If cur- rent illiquidity in the ARS market does not improve, if issuers of our ARS are unable to refinance the underly- ing securities, or are unable to pay debt obligations and related bond insurance fails, or if credit ratings decline or other adverse developments occur in the credit mar- kets, then we may not be able to monetize these securi- ties in the foreseeable future. We may also be required to further adjust the carrying value of these instruments through an impairment charge that may be deemed other-than-temporary which would adversely affect our financial results. Our Inability to Attract and Retain Key Personnel Could Cause Our Business to Suffer If we fail to attract and retain the necessary managerial, technical and customer support personnel, our business and our ability to maintain existing and obtain new cus- tomers, develop new products and provide acceptable levels of customer service could suffer. We compete with other industry participants for qualified personnel, particularly those with significant experience in the semiconductor industry. The loss of services of key employees could harm our business and results of operations. Risks Relating to the Market for Our Common Stock The Market Price May Fluctuate Significantly and Rapidly The market price of our common stock has fluctuated and could continue to fluctuate significantly as a result of factors such as: economic and stock market condi- tions generally and specifically as they may impact par- ticipants in the semiconductor and related industries; changes in financial estimates and recommendations by securities analysts who follow our stock; earnings and other announcements by, and changes in market evalu- ations of, us or participants in the semiconductor and related industries; changes in business or regulatory conditions affecting us or participants in the semicon- ductor and related industries; announcements or imple- mentation by us, our competitors, or our customers of technological innovations, new products or different business strategies; changes in our capital management strategy, including the incurrence of debt; and trading volume of our common stock. Anti-Takeover Provisions Under Our Certificate of Incorporation and Bylaws May Discourage Third Parties from Making an Unsolicited Bid for Our Company Our certificate of incorporation, our bylaws, and various provisions of the Delaware General Corporation Law may make it more difficult or expensive to effect a change in control of our Company. For instance, our amended and restated certificate of incorporation pro- vides for the division of our Board of Directors into three classes as nearly equal in size as possible with staggered three-year terms. We have adopted change in control arrangements cov- ering our executive officers and other key employees. These arrangements provide for a cash severance pay- ment, continued medical benefits and other ancillary payments and benefits upon termination of service of a covered employee’s employment following a change in control, which may make it more expensive to acquire our Company. Item 1B. Unresolved Staff Comments None. Item 2. Properties Our principal U.S. facilities that we or our subsidiaries own consist of: • a global headquarters and research and development facility in Aurora, Illinois, comprising approximately 200,000 square feet; • a commercial slurry manufacturing plant and distribu- tion center in Aurora, Illinois, comprising approxi- mately 175,000 square feet; • a commercial polishing pad manufacturing plant and offices in Aurora, Illinois, comprising approximately 48,000 square feet; • an additional 13.2 acres of vacant land in Aurora, Illinois; and • a facility in Addison, Illinois, comprising approximately 15,000 square feet.

We believe that our facilities are suitable and adequate for their intended purpose and provide us with sufficient capacity and capacity expansion opportunities and tech- nological capability to meet our current and expected demand in the foreseeable future. Item 3. Legal Proceedings While we are not involved in any legal proceedings that we believe will have a material impact on our consoli- dated financial position, results of operations or cash flows, we periodically become a party to legal proceed- ings in the ordinary course of business. For example, in 2011, we concluded litigation in the United States against a competitor in which the validity of certain of our CMP slurry patents for tungsten CMP was upheld, although the specific competitive products at issue were found to not infringe the claims at issue.

Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities Our common stock has traded publicly under the symbol “CCMP” since our initial public offering in April 2000, currently on the NASDAQ Global Select Market, and formerly the NASDAQ National Market. The following table sets forth the range of quarterly high and low closing sales prices for our common stock. Fiscal 2011 First Quarter Second Quarter Third Quarter Fourth Quarter Fiscal 2012 First Quarter Second Quarter Third Quarter Fourth Quarter Fiscal 2013 First Quarter (through October 31, 2012) High Low $42.80 52.25 51.88 48.21 $48.39 52.50 39.82 35.93 $32.22 40.80 43.18 34.39 $33.09 33.89 28.11 28.14 $35.09 $29.17 As of October 31, 2012, there were approximately 929 holders of record of our common stock. In December 2011, we announced a new capital management initiative for our Company, which included a leveraged recapital- ization with a special cash dividend of $15 per share and an increase in the amount available under our share repurchase program. On February 13, 2012, our Board of Directors declared the special cash dividend of $15 per share, or $347.1 million in aggregate, to the Company’s stockholders with a dividend payment date of March 1, 2012. The low price of our common stock shown above for the second quarter of fiscal 2012, as well as the high and low prices shown for the third and fourth quarters of fiscal 2012, reflect the period after the payment of the special cash dividend. No dividends were declared or paid in fiscal 2011 or prior to the special cash dividend, and we have no current plans to pay cash dividends in the future.

Management’s Discussion and Analysis of Financial Condition and Results of Operations The following “Management’s Discussion and Analysis of Financial Condition and Results of Operations” (MD&A), as well as disclosures included elsewhere in this Form 10-K, include “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. This Act provides a safe harbor for forward-looking statements to encourage companies to provide prospective information about themselves so long as they identify these statements as forward-looking and provide meaningful cautionary statements identify- ing important factors that could cause actual results to differ from the projected results. All statements other than statements of historical fact we make in this Form 10-K are forward-looking. In particular, the statements herein regarding future sales and operating results; Company and industry growth, contraction or trends; growth or contraction of the markets in which the Company participates; international events, regulatory or legislative activity, or various economic factors; prod- uct performance; the generation, protection and acqui- sition of intellectual property, and litigation related to such intellectual property; new product introductions; development of new products, technologies and mar- kets; natural disasters; the acquisition of or investment in other entities; uses and investment of the Company’s cash balance; financing facilities and related debt, pay- ment of principal and interest, and compliance with cov- enants and other terms; and the construction and operation of facilities by the Company; and statements preceded by, followed by or that include the words “intends”, “estimates”, “plans”, “believes”, “expects”, “anticipates”, “should”, “could” or similar expressions, are forward-looking statements. Forward-looking state- ments reflect our current expectations and are inher- ently uncertain. Our actual results may differ significantly from our expectations. We assume no obligation to update this forward-looking information. The section entitled “Risk Factors” describes some, but not all, of the factors that could cause these differences. The following discussion and analysis should be read in conjunction with our historical financial statements and the notes to those financial statements which are included in Item 8 of Part II of this Form 10-K. Overview Cabot Microelectronics Corporation (“Cabot Microelec- tronics”, “the Company”, “us”, “we”, or “our”) supplies high-performance polishing slurries and pads used in the manufacture of advanced integrated circuit (IC) devices within the semiconductor industry, in a process called chemical mechanical planarization (CMP). CMP polishes surfaces at an atomic level, thereby enabling IC device manufacturers to produce smaller, faster and more complex IC devices with fewer defects. We oper- ate predominantly in one industry segment—the devel- opment, manufacture and sale of CMP consumables. We develop, produce and sell CMP slurries for polishing many of the conducting and insulating materials used in IC devices, and also for polishing the disk substrates and magnetic heads used in hard disk drives. We also develop, manufacture and sell CMP polishing pads, which are used in conjunction with slurries in the CMP process. We also pursue other demanding surface mod- ification applications through our Engineered Surface Finishes (ESF) business where we believe we can lever- age our expertise in CMP consumables for the semicon- ductor industry to develop products for demanding polishing applications in other industries. In December 2011, we announced a new capital man- agement initiative for our Company, which included a planned leveraged recapitalization with a special cash dividend and an increase in the authorization available under our existing share repurchase program, which we believed would more efficiently allocate the Company’s capital and provide additional value to our stockhold- ers. In the second quarter of fiscal 2012, we completed the leveraged recapitalization and paid the special cash dividend. We entered into a credit agreement (the “Credit Agreement”), which provided us with a $175.0 million, five-year term loan (the “Term Loan”), and a $100.0 million revolving credit facility (the “Revolving Credit Facility”). See “Liquidity and Capital Resources” later in this MD&A for a more detailed discussion of our Credit Agreement. On February 13, 2012, our Board of Directors declared a special cash dividend of $15 per share to the Company’s stockholders with a dividend payment date of March 1, 2012. The dividend, in the aggregate amount of $347.1 million, was paid on the dividend payment date, with $175.0 million funded by the Term Loan and the remaining $172.1 million funded with existing Company cash balances. Our fiscal 2012 results reflected a strengthening of demand for our products during the second half of the fiscal year after the soft industry demand conditions we saw during the first half of the fiscal year. We saw solid demand in Korea and at certain foundries within the semiconductor industry, partially offset by what we believe was softer demand from the DRAM memory segment. At the end of our fourth fiscal quarter of 2012, we began to see signs of softening of demand within the semiconductor industry that we believe may persist into calendar 2013. There appears to be uncertainty within the industry, which is compounded by continued macroeconomic uncertainty. However, we believe there are long-term growth opportunities with the continua- tion of positive trends in mobile connectivity, mobile Internet devices, such as tablets and smart phones, 21 cloud computing and emerging markets. There are many factors that make it difficult for us to predict future revenue trends for our business, including those discussed in Part I, Item 1A entitled “Risk Factors” in this Form 10-K. Revenue for fiscal 2012 was $427.7 million, which repre- sented a decrease of 4.0% from the record $445.4 mil- lion reported for fiscal 2011. The decrease in revenue from fiscal 2011 was primarily due to the soft industry conditions during the first half of the fiscal year. In spite of the challenging industry and macroeconomic condi- tions, we were able to grow both our polishing pads business and our ESF business. We also increased our revenue in South Korea by approximately 22% from fis- cal 2011. South Korea has been an area of strategic emphasis for the Company since it represents the sec- ond largest CMP consumables market in the world. Gross profit expressed as a percentage of revenue for fiscal 2012 was 47.7%, which represents a decrease from the 48.1% reported for fiscal 2011, but was near the upper end of our full year guidance range of 46% to 48% of revenue. The decrease in gross profit percentage from fiscal 2011 was primarily due to higher fixed manu- facturing costs, pricing impacts, and lower sales and production volumes, partially offset by lower variable manufacturing costs and higher manufacturing yields. We expect our gross profit for full fiscal year 2013 to continue to be in the range of 46% to 48% of revenue. However, we may experience fluctuations in our gross profit due to a number of factors, including the extent to which we utilize our manufacturing capacity and changes in our product mix, which may cause our quar- terly gross profit to be above or below this range. Operating expenses of $137.5 million, which include research, development and technical, selling and mar- keting, and general and administrative expenses, increased 2.8%, or $3.8 million, from the $133.7 million reported for fiscal 2011. The increase was primarily due to bad debt expense related to a customer bankruptcy that we reported in the second quarter of fiscal 2012, costs associated with our leveraged recapitalization with a special cash dividend, and higher expenses for research and development materials. These increases were partially offset by lower staffing-related costs. In fiscal 2013, we expect our full year operating expenses to be in the range of $132 million to $136 million. Diluted earnings per share of $1.75 in fiscal 2012 decreased 20.4%, or $0.45, from the record $2.20 reported in fiscal 2011. The decrease was primarily due to decreased sales volume, a lower gross profit percentage, higher operat- ing expenses noted above, and interest expense on our Term Loan. Diluted earnings per share in fiscal 2012 included $0.20 in adverse items including the bad debt expense related to a customer bankruptcy and costs associated with our leveraged recapitalization with a special cash dividend, as well as $0.06 for interest expense on our Term Loan. Critical Accounting Policies and Estimates This MD&A, as well as disclosures included elsewhere in this Form 10-K, are based upon our audited consoli- dated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclo- sure of contingencies. On an ongoing basis, we evaluate the estimates used, including those related to bad debt expense, warranty obligations, inventory valuation, valu- ation and classification of auction rate securities, impair- ment of long-lived assets and investments, business combinations, goodwill, other intangible assets, share- based compensation, income taxes and contingencies. We base our estimates on historical experience, current conditions and on various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources, as well as for identifying and assessing our accounting treatment with respect to commitments and contingencies. Actual results may differ from these estimates under different assumptions or conditions. We believe the following critical accounting policies involve significant judgments and estimates used in the preparation of our consoli- dated financial statements. Allowance for Doubtful Accounts We maintain an allowance for doubtful accounts for esti- mated losses resulting from the potential inability of our customers to make required payments. Our allowance for doubtful accounts is based on historical collection experience, adjusted for any specific known conditions or circumstances. While historical experience may pro- vide a reasonable estimate of uncollectible accounts, actual results may differ from what was recorded. In fis- cal 2012, we recorded $3.7 million in bad debt expense for Elpida Memory, Inc. (Elpida), a significant customer in Japan that filed for bankruptcy protection in February 2012. We will continue to monitor the financial solvency of all of our customers and, if global economic condi- tions worsen, we may have to record additional increases to our allowance for doubtful accounts. As of September 30, 2012, our allowance for doubtful accounts repre- sented 8.2% of gross accounts receivable. If we had increased our estimate of bad debts to 9.2% of gross accounts receivable, our general and administrative expenses would have increased by $0.6 million. 22 Warranty Reserve We maintain a warranty reserve that reflects manage- ment’s best estimate of the cost to replace product that does not meet customers’ specifications and perfor- mance requirements, and costs related to such replace- ment. The warranty reserve is based upon a historical product replacement rate, adjusted for any specific known conditions or circumstances. Should actual war- ranty costs differ substantially from our estimates, revi- sions to the estimated warranty liability may be required. As of September 30, 2012, our warranty reserve repre- sented 0.3% of the current quarter revenue. If we had increased our warranty reserve estimate to 1.3% of the current quarter revenue, our cost of goods sold would have increased by $1.1 million. Inventory Valuation We value inventory at the lower of cost or market and write down the value of inventory for estimated obsoles- cence or if inventory is deemed unmarketable. An inven- tory reserve is maintained based upon a historical percentage of actual inventories written off applied against the inventory value at the end of the period, adjusted for known conditions and circumstances. We exercise judgment in estimating the amount of inven- tory that is obsolete. Should actual product market- ability and fitness for use be affected by conditions that are different from those projected by management, revisions to the estimated inventory reserve may be required. If we had increased our reserve for obsolete inventory at September 30, 2012 by 10%, our cost of goods sold would have increased by $0.2 million. Valuation and Classification of Auction Rate Securities As of September 30, 2012, we owned two auction rate securities (ARS) with an estimated fair value of $8.0 mil- lion ($8.2 million par value) which are classified as other long-term assets on our Consolidated Balance Sheet. In general, ARS investments are securities with long-term nominal maturities for which interest rates are reset through a Dutch auction every seven to 35 days. Historically, these periodic auctions provided a liquid market for these securities. Beginning in 2008, general uncertainties in the global credit markets reduced liquidity in the ARS market, and this illiquidity continues. As discussed in Notes 3 and 7 of the Notes to the Consolidated Financial Statements, we have recorded a temporary impairment of $0.2 million, net of tax, in the value of one of our ARS in other comprehensive income. The calculation of fair value and the balance sheet clas- sification for our ARS requires critical judgments and estimates by management including an appropriate dis- count rate and the probabilities that a security may be monetized through a future successful auction, of a refi- nancing of the underlying debt, of a default in payment by the issuer, and of payments not being made by the bond insurance carrier in the event of default by the issuer. An other-than-temporary impairment must be recorded when a credit loss exists; that is when the present value of the expected cash flows from a debt security is less than the amortized cost basis of the secu- rity. We performed two discounted cash flow analyses, one using a discount rate based on a market index com- prised of tax exempt variable rate demand obligations and one using a discount rate based on the LIBOR swap curve, and we applied a risk factor to reflect current liquidity issues in the ARS market. Key inputs to our dis- counted cash flow model include projected cash flows from interest and principal payments and the weighted probabilities of improved liquidity or debt refinancing by the issuer. We also incorporate certain Level 2 market indices into the discounted cash flow analysis, including published rates such as the LIBOR rate, the LIBOR swap curve and a municipal swap index published by the Securities Industry and Financial Markets Association. We also considered the probability of default in pay- ment by the issuer of the securities, the strength of the insurance backing and the probability of failure by the insurance carrier in the case of default by the issuer of the securities. In November 2011, the municipality that issued our impaired ARS filed for bankruptcy protection. We considered these developments, in light of the continued insurance backing, and have concluded the impairment we have maintained remains adequate and temporary. We do not intend to sell the securities at a loss and we believe we will not be required to sell the securities at a loss in the future. If auctions involving our ARS continue to fail, if issuers of our ARS are unable to refinance the underlying securities, if the issuing munici- palities are unable to pay their debt obligations and the bond insurance fails, or if credit ratings decline or other adverse developments occur in the credit markets, we may not be able to monetize our securities in the near term and may be required to further adjust the carrying value of these instruments through an impairment charge that may be deemed other-than-temporary. Impairment of Long-Lived Assets and Investments We assess the recoverability of the carrying value of long-lived assets, including finite lived intangible assets, whenever events or changes in circumstances indicate that the assets may be impaired. We must exercise judg- ment in assessing whether an event of impairment has occurred. For purposes of recognition and measure- ment of an impairment loss, long-lived assets are grouped with other assets and liabilities at the lowest level for which identifiable cash flows are largely inde- pendent of the cash flows of other assets and liabilities. We must exercise judgment in this grouping. If the sum of the undiscounted future cash flows expected to result from the identified asset group is less than the carrying value of the asset group, an impairment provision may 23 be required. The amount of the impairment to be rec- ognized is calculated by subtracting the fair value of the asset group from the net book value of the asset group. Determining future cash flows and estimating fair values require significant judgment and are highly susceptible to change from period to period because they require management to make assumptions about future sales and cost of sales generally over a long-term period. As a result of assessments performed during fiscal 2012, we recorded $1.0 million in impairment expense primarily related to the decision to write-off certain operational assets at one of our foreign locations. In each of fiscal years 2011 and 2010, we recorded $0.2 million in impair- ment expense. We evaluate the estimated fair value of investments annually or more frequently if indicators of potential impairment exist, to determine if an other-than-temporary impairment in the value of the investment has taken place. Business Combinations We have accounted for all business combinations under the purchase method of accounting. As discussed in more detail in Note 3 of the Notes to the Consolidated Financial Statements, we were required to adopt new accounting standards for business combinations com- mencing after October 1, 2009. However, we have not made any acquisitions to which we were required to apply these new standards. We have allocated the purchase price of acquired entities to the tangible and intangible assets acquired, liabilities assumed, and in-process research and development (IPR&D) based on their estimated fair values. We engage independent third-party appraisal firms to assist us in determining the fair values of assets and liabilities acquired. This valuation requires management to make significant esti- mates and assumptions, especially with respect to long- lived and intangible assets. Contingent consideration was recorded as a liability when the outcome of the con- tingency became determinable. Goodwill represents the excess of the purchase price over the fair value of net assets and amounts assigned to identifiable intan- gible assets. Purchased IPR&D, for which technological feasibility has not yet been established and no future alternative uses exist, has been expensed immediately. Critical estimates in valuing certain of the intangible assets include but are not limited to: future expected cash flows related to acquired developed technologies and patents and assumptions about the period of time the technologies will continue to be used in the Com- pany’s product portfolio; expected costs to develop the IPR&D into commercially viable products and estimated cash flows from the products when completed; and dis- count rates. Management’s estimates of value are based upon assumptions believed to be reasonable, but which are inherently uncertain and unpredictable. Assumptions may be incomplete or inaccurate, and unanticipated events and circumstances may occur which may cause actual realized values to be different from manage- ment’s estimates. Goodwill and Intangible Assets Purchased intangible assets with finite lives are amor- tized over their estimated useful lives and are evaluated for impairment using a process similar to that used to evaluate other long-lived assets. Goodwill and indefinite- lived intangible assets are not amortized and are tested annually in the fourth fiscal quarter or more frequently if indicators of potential impairment exist, using a fair- value-based approach. The recoverability of goodwill is measured at the report- ing unit level, which is defined as either an operating segment or one level below an operating segment. A component is a reporting unit when the component constitutes a business for which discreet financial infor- mation is available and segment management regularly reviews the operating results of the component. Components may be combined into one reporting unit when they have similar economic characteristics. We had three reporting units to which we allocated good- will and intangible assets as of September 30, 2012, the date of our annual impairment test. Initially, our Company had only one reporting unit as we were cre- ated from a division of our former parent company, Cabot Corporation, and we identified associated good- will and intangible assets under one reporting unit at that time. Other amounts of goodwill and intangible assets have been attributed to acquired businesses at the time of acquisition through the use of independent appraisal firms. Prior to fiscal 2011, we determined the fair value of our reporting units using a discounted cash flow analysis (“step one” analysis) of our projected future results. As discussed in Notes 2 and 6 of the Notes to the Consolidated Financial Statements, effective September 30, 2011, we adopted new accounting pronouncements related to our goodwill impairment analysis. The new accounting guidance allows an entity to first assess qualitative factors to determine if it is more likely than not that the fair value of a reporting unit is less than its carrying amount (“step zero” analysis). In fiscal 2012 and 2011, we used this new guidance in our annual impair- ment analysis for goodwill because our cash flows for all of our reporting units continued to show positive trends. Prior to fiscal 2012, the recoverability of indefinite-lived intangible assets was measured using the royalty savings method. As discussed in Notes 2 and 6 of the Notes to the Consolidated Financial Statements, effec- tive September 30, 2012, we adopted new accounting 24 pronouncements related to our indefinite-lived intan- gible assets impairment review. The new accounting guidance allows an entity to first assess qualitative fac- tors to determine if it is more likely than not that the fair value of an indefinite-lived intangible asset unit is less than its carrying amount. In fiscal 2012, we used this new guidance in our annual impairment review. As a result of the review performed in the fourth quarter of fiscal 2012, we determined that there was no impair- ment of our goodwill and intangible assets as of September 30, 2012. Share-Based Compensation We record share-based compensation expense for all share-based awards, including stock option grants, restricted stock and restricted stock unit awards and employee stock purchases. We calculate share-based compensation expense using the straight-line approach based on awards ultimately expected to vest, which requires the use of an estimated forfeiture rate. Our estimated forfeiture rate is primarily based on historical experience, but may be revised in future periods if actual forfeitures differ from the estimate. We use the Black-Scholes option-pricing model to estimate the grant date fair value of our stock options and employee stock purchase plan purchases. This model requires the input of highly subjective assumptions, including the price volatility of the underlying stock, the expected term of our stock options and the risk-free interest rate. We estimate the expected volatility of our stock options based on a combination of our stock’s historical volatil- ity and the implied volatilities from actively-traded options on our stock. Prior to fiscal 2012, we calculated the expected term of our stock options using the simpli- fied method, due to our limited amount of historical option exercise data, and we added a slight premium to this expected term for employees who meet the defini- tion of retirement eligible pursuant to their grants dur- ing the contractual term of the grant. The simplified method uses an average of the vesting term and the contractual term of the option to calculate the expected term. We experienced a significant increase in the vol- ume of stock option exercises in fiscal 2011. Conse- quently, we used this exercise data, as well as historical exercise data, to calculate the expected term of our stock options granted in fiscal 2012, rather than using the simplified method, and we continued to add a slight premium for employees who meet the definition of retirement eligible under their grant terms. The expected term we calculated using option exercise his- tory was within 1% of the expected term calculated under the simplified method. The risk-free rate is derived from the U.S. Treasury yield curve in effect at the time of grant. The fair value of our restricted stock and restricted stock unit awards represents the closing price of our common stock on the date of award. Accounting for Income Taxes Current income taxes are determined based on esti- mated taxes payable or refundable on tax returns for the current year. Deferred income taxes are determined using enacted tax rates for the effect of temporary dif- ferences between the book and tax bases of recorded assets and liabilities. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Provisions are made for both U.S. and any foreign deferred income tax liability or benefit. We recognize the tax benefit of an uncertain tax position only if it is more likely than not that the tax position will be sus- tained by the taxing authorities, based on the technical merits of the position. In fiscal 2012, 2011 and 2010, we elected to permanently reinvest the earnings of certain of our foreign subsidiaries outside the U.S. rather than repatriating the earnings to the U.S. See the section titled “Liquidity and Capital Resources” in this MD&A and Note 15 of the Notes to the Consolidated Financial Statements for additional information on income taxes and permanent reinvestment. Commitments and Contingencies We have entered into certain unconditional purchase obligations, which include noncancelable purchase commitments and take-or-pay arrangements with sup- pliers. We review our agreements on a quarterly basis and make an assessment of the likelihood of a shortfall in purchases and determine if it is necessary to record a liability. In addition, we are subject to the possibility of various loss contingencies arising in the ordinary course of business such as a legal proceeding or claim. An estimated loss contingency is accrued when it is probable that an asset has been impaired or a liability has been incurred and the amount of the loss can be reasonably estimated. We regularly evaluate current information available to us to determine whether such accruals should be adjusted and whether new accruals are required. Effects of Recent Accounting Pronouncements See Note 2 to the Consolidated Financial Statements for a description of recent accounting pronouncements including the expected dates of adoption and effects on our results of operations, financial position and cash flows. 25 Results of Operations The following table sets forth, for the periods indicated, the percentage of revenue of certain line items included in our historical statements of income: Year Ended September 30, 2012 2011 2010 Revenue Cost of goods sold Gross profit Research, development and technical Selling and marketing General and administrative Operating income Interest expense Other income (expense), net Income before income taxes Provision for income taxes 100.0% 100.0% 100.0% 51.9 50.1 52.3 47.7 48.1 49.9 13.7 6.9 11.6 15.5 0.5 (0.3) 14.7 5.2 13.1 6.7 10.3 18.0 0.0 (0.3) 17.7 6.1 12.7 6.6 12.5 18.1 0.1 (0.1) 17.9 5.8 Net income 9.5% 11.6% 12.1% The results of operations for fiscal 2012 include certain adjustments to correct prior period amounts, which we have determined to be immaterial to the current period and the prior periods to which they relate. These adjust- ments included the correction of historical tax account- ing related to the acquisition of Epoch Material Co., Ltd. (Epoch) in fiscal 2009 and the correction of prior period remeasurement of certain foreign cash balances into their functional currency amounts, which were recorded in the third quarter of fiscal 2012, and the correction of additional historical tax accounting recorded in the fourth quarter of fiscal 2012. The correction of tax accounting related to the Epoch acquisition resulted in additional income tax expense of $0.2 million in the Consolidated Statement of Income and adjustments to the Consolidated Balance Sheet including: an increase of $2.2 million of cumulative translation adjustment within accumulated other comprehensive income (CTA); an increase in goodwill of $1.7 million; and a decrease of $0.3 million in deferred tax liabilities. The correction of the historical remeasurement of certain foreign cash balances resulted in $0.3 million of additional expense ($0.2 million, net of tax) included in other income (Expense) on the Consolidated Statement of Income. The correction of tax accounting in the fourth quarter resulted in additional income tax expense of $0.8 million and adjustments to the Consolidated Balance Sheet including: a decrease of $1.1 million in deferred tax lia- bilities; a decrease of $0.1 million in deferred tax assets; a decrease of $0.9 million in income taxes receivable; and an increase of $1.0 million in CTA. Collectively, these adjustments reduced net income for fiscal 2012 by $1.2 million and diluted earnings per share for the same period by approximately $0.05. 26 Year Ended September 30, 2012, Versus Year Ended September 30, 2011 Revenue Revenue was $427.7 million in fiscal 2012, which repre- sented a decrease of 4.0%, or $17.8 million, from fiscal 2011. The decrease in revenue was driven by a $29.3 mil- lion decrease in sales volume and a $6.1 million decrease due to pricing impacts. These decreases were partially offset by a $16.1 million increase in revenue due to a higher-priced product mix and a $1.3 million increase due to the effect of foreign exchange rate changes. Revenue from our polishing pad business increased 8.6% from fiscal 2011 and revenue from our ESF business increased slightly. Revenue in fiscal 2012 from our tung- sten, dielectric, copper and data storage slurry product lines all decreased from fiscal 2011. We saw a strength- ening of demand in the second half of fiscal 2012 after a period of softer demand during the first half of the fiscal year. However, we began to see signs of softening of demand at the end of our fourth fiscal quarter which may extend into calendar 2013. We continue to be cau- tious regarding future demand trends due to uncer- tainty within the semiconductor industry, compounded by continued macroeconomic uncertainty. Cost of Goods Sold Total cost of goods sold was $223.6 million in fiscal 2012, which represented a decrease of 3.3%, or $7.7 million, from fiscal 2011. The decrease in cost of goods sold was primarily due to $15.2 million from decreased sales vol- ume, an $8.4 million decrease due to higher manufactur- ing yields, and a $1.9 million decrease due to lower logistics costs. These decreases in cost of goods sold were partially offset by a $11.5 million increase due to a higher-cost product mix, a $4.4 million increase due to higher fixed manufacturing costs, including costs at our new facility in South Korea, and a $1.5 million increase due to the effect of foreign exchange rate changes. Metal oxides, such as silica and alumina, are significant raw materials that we use in many of our CMP slurries. In an effort to mitigate our risk to rising raw material costs and to increase supply assurance and quality perfor- mance requirements, we have entered into multi-year supply agreements with a number of suppliers. For more financial information about our supply contracts, see “Tabular Disclosure of Contractual Obligations” included in Item 7 of Part II of this Form 10-K. Our need for additional quantities or different kinds of key raw materials in the future has required, and will continue to require, that we enter into new supply arrangements with third parties. Future arrangements may result in costs which are different from those in the existing agreements. In addition, a number of factors could impact the future cost of raw materials, packag- ing, freight and labor. We also expect to continue to invest in our supply chain to improve product quality, reduce variability and improve our manufacturing prod- uct yields. Gross Profit Our gross profit as a percentage of revenue was 47.7% in fiscal 2012 as compared to 48.1% for fiscal 2011. The decrease in gross profit as a percentage of revenue was primarily due to higher fixed manufacturing costs, pric- ing impacts and decreased sales and production vol- umes, partially offset by lower variable manufacturing costs and higher manufacturing yields. We expect our gross profit percentage for full fiscal year 2013 to be in the range of 46% to 48%, which is unchanged from the full year guidance for fiscal 2012. However, we may expe- rience fluctuations in our gross profit due to a number of factors, including the extent to which we utilize our manufacturing capacity and changes in our product mix, which may cause our quarterly gross profit to be above or below this range. Research, Development and Technical Total research, development and technical expenses were $58.6 million in fiscal 2012, which represented an increase of 1.0%, or $0.6 million, from fiscal 2011. The increase was primarily due to $1.5 million in higher expenses for research and development materials and $0.5 million in higher sample costs, partially offset by $1.6 million in lower staffing-related costs, including costs related to our annual incentive cash bonus pro- gram (AIP). Our research, development and technical efforts are focused on the following main areas: • Research related to fundamental CMP technology; • Development and formulation of new and enhanced CMP consumable products, including collaboration on joint development projects with our customers; • Process development to support rapid and effective commercialization of new products; • Technical support of CMP products in our customers’ development and manufacturing facilities; and, • Evaluation and development of new polishing and metrology applications outside of the semiconductor industry. Selling and Marketing Selling and marketing expenses were $29.5 million in fis- cal 2012, which represented a decrease of 0.8%, or $0.2 million, from fiscal 2011. The decrease was primarily due to $0.5 million in lower depreciation and amortization expense and $0.3 million in lower professional fees, partially offset by $0.4 million in higher staffing related costs. General and Administrative General and administrative expenses were $49.3 million in fiscal 2012, which represented an increase of 7.4%, or $3.4 million, from fiscal 2011. The increase was primarily due to $3.8 million in higher bad debt expense, of which $3.7 million related to a customer bankruptcy filing, and $1.5 million in higher professional fees, including fees associated with our leveraged recapitalization with a special cash dividend. These increases were partially offset by $1.8 million in lower staffing-related costs, including costs associated with our AIP. Interest Expense Interest expense was $2.3 million in fiscal 2012, which represented an increase of $2.2 million from fiscal 2011. The increase was due to interest expense recorded on the Term Loan, as discussed in the Overview section of this MD&A and in Note 9 of the Notes to the Consoli- dated Financial Statements, which was used to partially fund the special cash dividend we paid in fiscal 2012. Other Income (Expense), Net Other expense was $1.3 million in both fiscal 2012 and 2011. Other expense includes $0.3 million in amortiza- tion of prepaid debt costs as well as gains and losses on transactions denominated in foreign currencies, primar- ily related to changes in the exchange rate of the Japanese yen and the New Taiwan dollar to the U.S. dol- lar, net of the gains and losses incurred on forward foreign exchange contracts discussed in Note 10 of the Notes to the Consolidated Financial Statements. Provision for Income Taxes Our effective income tax rate was 35.1% in fiscal 2012 compared to 34.5% in fiscal 2011. The increase in the effective tax rate was primarily due the expiration of the U.S. research and experimentation tax credit effective December 31, 2011, decreased income in certain foreign subsidiaries where we have elected to permanently rein- vest earnings, which are taxed at lower rates than in the U.S., and certain adjustments made to prior year tax estimates. These increases were partially offset by decreased tax effects on share-based compensation and the decreased taxable executive compensation in excess of limits defined in section 162(m) of the Internal Revenue Code. As discussed above at the beginning of the “Results of Operations” section of this MD&A, our income tax provision in fiscal 2012 included various non- material adjustments to correct prior period amounts, which resulted in additional income tax expense of $1.0 million. As discussed in our Annual Report on Form 10-K for the fiscal year ended September 30, 2011, our income tax provision in fiscal 2011 included adjustments to cor- rect prior period amounts, including $0.7 million in tax expense related to executive compensation in fiscal 27 2008 through 2010 for which a previous tax benefit should not have been recorded, and the reversal of a $0.5 million deferred tax asset related to certain share- based compensation expense. Net Income Net income was $40.8 million in fiscal 2012, which repre- sented a decrease of 21.0%, or $10.8 million, from fiscal 2011. The decrease was primarily due to decreased sales volume coupled with a lower gross profit percentage, increased bad debt expense related to a customer bankruptcy filing, the expenses associated with our lev- eraged recapitalization with a special cash dividend, increased interest expense and a higher effective tax rate. Year Ended September 30, 2011, Versus Year Ended September 30, 2010 Revenue Revenue was $445.4 million in fiscal 2011, which repre- sented an increase of 9.1%, or $37.2 million, from fiscal 2010. The increase in revenue was driven by a $35.6 mil- lion increase in sales volume, a $5.5 million increase due to the effect of foreign exchange rate changes, and a $4.7 million increase due to a higher-priced product mix. These increases were partially offset by an $8.9 million decrease in revenue due to pricing impacts. The economic and industry growth that we saw during fiscal 2010 continued into fiscal 2011. However, we saw some softening of demand in the semiconductor industry in the second half of fiscal 2011 based on certain factors, including general uncertainty in the global economy and a modest correction of integrated circuit (IC) device inventory. Cost of Goods Sold Total cost of goods sold was $231.3 million in fiscal 2011, which represented an increase of 13.0%, or $26.6 million, from fiscal 2010. The increase in cost of goods sold was primarily due to $17.8 million from increased sales vol- ume due to increased demand for our products, a $9.5 million increase due to the effect of foreign exchange rate changes, a $6.9 million increase due to higher fixed manufacturing costs, a $1.8 million increase due to higher freight and packaging costs, a $1.3 million increase due to certain production variances and a $0.7 million increase due to higher sample costs. These increases were partially offset by an $11.5 million decrease in cost of goods sold due to a lower-cost product mix. Gross Profit Our gross profit as a percentage of revenue was 48.1% in fiscal 2011 as compared to 49.9% for fiscal 2010. The decrease in gross profit as a percentage of revenue was primarily due to higher fixed manufacturing costs, the negative effects of foreign exchange rate changes, pricing impacts and the absence of a raw material sup- plier credit we recognized in the first quarter of fiscal 2010 related to our achieving a certain volume threshold in calendar 2009, partially offset by a higher-valued product mix. Research, Development and Technical Total research, development and technical expenses were $58.0 million in fiscal 2011, which represented an increase of 12.0%, or $6.2 million, from fiscal 2010. The increase was primarily due to $3.6 million in higher staffing-related costs, related to higher staffing levels and separation costs related to the transition of one of our executive officers, and $2.2 million in higher expenses for research and development materials. Selling and Marketing Selling and marketing expenses were $29.8 million in fiscal 2011, which represented an increase of 10.7%, or $2.9 million, from fiscal 2010. The increase was primarily due to $1.3 million in higher staffing related costs, $0.6 million in higher travel-related costs and $0.4 million in higher miscellaneous selling expenses. General and Administrative General and administrative expenses were $45.9 million in fiscal 2011, which represented a decrease of 9.6%, or $4.9 million, from fiscal 2010. The decrease was primarily due to $6.8 million in lower professional fees, including costs to enforce our intellectual property, partially offset by $1.1 million in higher staffing-related costs and $0.6 million in higher depreciation expense. See Part I, Item 3 entitled “Legal Proceedings” and Note 16 of the Notes to the Consolidated Financial Statements for more infor- mation on the enforcement of our intellectual property. Interest Expense Interest expense was $0.2 million in both fiscal 2011 and 2010, which primarily represented interest expense on our capital lease obligations. Other Income (Expense), Net Other expense was $1.3 million in fiscal 2011, compared to $0.5 million during fiscal 2010. The increase in other expense was primarily due to $1.1 million in foreign exchange effects, primarily related to changes in the exchange rate of the Japanese yen and the New Taiwan dollar to the U.S. dollar, net of the gains and losses incurred on forward foreign exchange contracts dis- cussed in Note 10 of the Notes to the Consolidated Financial Statements. 28 Provision for Income Taxes Our effective income tax rate was 34.5% in fiscal 2011 compared to 32.5% in fiscal 2010. The increase in the effective tax rate was primarily due to a number of factors related to share-based compensation expense, including tax impacts of stock option exercises and the vesting of restricted stock for certain employees, and taxable executive compensation in excess of limits defined in section 162(m) of the Internal Revenue Code, partially offset by the reinstatement of the U.S. research and experimentation tax credit in December 2010, which was retroactively effective as of January 1, 2010. Our income tax provision in fiscal 2011 included adjustments to correct prior period amounts, including $0.7 million in tax expense related to executive compensation in fiscal 2008 through 2010 for which a previous tax benefit should not have been recorded, and the reversal of a $0.5 million deferred tax asset related to certain share- based compensation expense. Net Income Net income was $51.7 million in fiscal 2011, which repre- sented an increase of 4.5%, or $2.2 million, from fiscal 2010. The increase was primarily due to increased sales volume, partially offset by a lower gross margin percent- age, increased operating expenses and a higher effec- tive tax rate. Liquidity and Capital Resources We completed a leveraged recapitalization during our fiscal quarter ended March 31, 2012. In conjunction with this recapitalization, we declared and paid a special cash dividend of $15 per share, or $347.1 million in aggregate. We funded the dividend with $175.0 million from our Term Loan and $172.1 million of existing Company cash balances. We had cash flows from operating activities of $66.4 mil- lion in fiscal 2012, $93.6 million in fiscal 2011 and $88.4 million in fiscal 2010. Our cash provided by operating activities in fiscal 2012 originated from $40.8 million in net income and $38.1 million in non-cash items, partially offset by a $12.5 million decrease in cash flow due to a net increase in working capital. The decrease in cash from operations in fiscal 2012 from fiscal 2011 was pri- marily due to decreased net income and increases in working capital amounts associated with higher invento- ries and gross accounts receivable. The increase in inventories was primarily due to raw material purchases made in the fourth quarter of fiscal 2012 for business continuity purposes as we negotiate the terms of a new supply agreement with an existing supplier to replace the current agreement, which will expire at the end of December 2012. These negative cash flow effects were partially offset by the increase in bad debt expense, which is a non-cash expense, and changes in the timing and magnitude of income tax payments. We used $19.7 million in investing activities in fiscal 2012, of which $19.6 million represented purchases of prop- erty, plant and equipment. Capital expenditures in fiscal 2012 included the completion of payment for the fiscal 2011 construction of our facility in South Korea. We used $28.2 million in investing activities in fiscal 2011 of which $28.1 million represented purchases of property, plant and equipment. Capital expenditures in fiscal 2011 included the majority of costs associated with the construction of our facility in South Korea and capacity expansions of our Japan and Singapore facilities, net of the amounts that remained in accounts payable and accrued expenses at the end of the fiscal year. We used $11.9 million in investing activities in fiscal 2010 repre- senting $11.7 million in purchases of property, plant and equipment and $0.2 million in other investing cash out- flows. We estimate that our total capital expenditures in fiscal 2013 will be between $20 million and $25 million. In fiscal 2012, cash flows used in financing activities were $171.7 million. We used $347.1 million to fund the special cash dividend paid in the quarter ended March 31, 2012, $33.0 million to repurchase common stock under our share repurchase program, $2.2 million to repay long- term debt and $1.5 million to repurchase common stock pursuant to the terms of our Second Amended and Restated Cabot Microelectronics Corporation 2000 Equity Incentive Plan (EIP) and our 2012 Omnibus Incentive Plan (OIP) for shares withheld from award recipients to cover payroll taxes on the vesting of restricted stock granted under our EIP and OIP. We received $175.0 million from the drawdown of our Term Loan, $36.5 million from the issuance of common stock related to the exercise of stock options granted under our EIP and the sale of shares to employees under our 2007 Employee Stock Purchase Plan, as amended and restated January 1, 2010 (ESPP), and we received $0.6 million in tax benefits related to exercises of stock options and vesting of restricted stock granted under our EIP. The issuance of stock in fiscal 2012 included 1.0 million shares in exercises of stock options, of which approximately half would have expired within one year, which increased our weighted average shares outstand- ing. In fiscal 2011, cash flows used in financing activities were $17.9 million. We used $54.1 million to repurchase common stock under our share repurchase program, $1.4 million to repurchase common stock pursuant to the terms of our EIP for shares withheld from award recipients to cover payroll taxes on the vesting of restricted stock granted under the EIP, and we made $1.3 million in principal payments under capital lease obligations. These cash outflows were partially offset by $38.1 million received from the issuance of common stock related to the exercise of stock options granted under our EIP and the sale of shares to employees under our ESPP. In addition, we received $0.8 million in tax benefits related to stock options exercised and vesting 29 of restricted stock awarded under our EIP. In fiscal 2010, cash flows used in financing activities were $23.5 million. We used $25.0 million to repurchase common stock under our share repurchase plan, $0.8 million to repurchase common stock pursuant to the terms of our EIP for shares withheld from award recipients by the Company to cover payroll taxes on the vesting of restricted stock granted under the EIP, and we made $1.2 million in principal payments under capital lease obligations. These cash outflows were partially offset by $3.4 million received from the issuance of common stock related to the exercise of stock options granted under our EIP and the sale of shares to employees under our ESPP. In November 2010, our Board of Directors authorized a share repurchase program for up to $125.0 million of our outstanding common stock, which became effective on the authorization date. We repurchased 671,100 shares for $29.1 million under this program in fiscal 2011 and we repurchased 929,407 shares for $33.0 million during fiscal 2012 under this program. As of December 13, 2011, we had $82.9 million remaining under this share repurchase program. In conjunction with our new capital management initiative, on December 13, 2011, our Board of Directors authorized an increase in the amount available under our share repurchase program to $150.0 million. With this increased authorization, as of September 30, 2012, $130.0 million remains outstanding under our share repurchase program. Share repurchases are made from time to time, depending on market con- ditions, in open market transactions, at management’s discretion. We repurchased 564,568 shares for $25.0 million during fiscal 2011 under a prior share repurchase program, which was completed during the fiscal quarter ended March 31, 2011. To date, we have funded share purchases under our share repurchase program from our available cash balance, and anticipate we will con- tinue to do so. We entered into a Credit Agreement in February 2012, which provided us with a $175.0 million Term Loan and a $100.0 million Revolving Credit Facility, with sub-limits for multicurrency borrowings, letters of credit and swing-line loans. The Term Loan and Revolving Credit Facility are referred to as the “Credit Facilities”. The Credit Agreement provides us an uncommitted accor- dion feature that allows us to request the existing lend- ers or, if necessary, third-party financial institutions to provide additional capacity in the Revolving Credit Facility, in an amount not to exceed $75.0 million. The Term Loan has periodic scheduled principal repayments; however, we may prepay the loan without penalty. The Credit Facilities are scheduled to expire on February 13, 2017. The Term Loan was drawn on February 27, 2012 and the Revolving Credit Facility remains undrawn. In connection with the Credit Agreement, we terminated our previously existing $50.0 million unsecured revolving credit facility. The Credit Agreement contains covenants that restrict the ability of the Company and its subsid- iaries to take certain actions, including, among other things and subject to certain significant exceptions: creating liens, incurring indebtedness, making invest- ments, engaging in mergers, selling property, paying dividends or amending organizational documents. The Credit Agreement requires us to comply with certain financial ratio maintenance covenants, including a maximum consolidated leverage ratio of 3.00 to 1.00 through June 30, 2013 and a minimum consolidated fixed charge coverage ratio of 1.25 to 1.00. As of September 30, 2012, our consolidated leverage ratio was 1.60 to 1.00 and our consolidated fixed charge cov- erage ratio was 10.93 to 1.00. The Credit Agreement also contains customary affirmative covenants and events of default. We believe we are in compliance with these covenants. See Note 9 of the Notes to the Consolidated Financial Statements for additional infor- mation regarding the Credit Agreement. As of September 30, 2012, we had $178.5 million of cash and cash equivalents, $27.9 million of which was held at foreign subsidiaries in Singapore and Taiwan where we have made a current election to permanently reinvest the earnings rather than repatriate the earnings to the U.S. If we choose to repatriate these earnings in the future through dividends or loans to the U.S. parent company, the earnings could become subject to addi- tional income tax expense. We believe that our current balance of cash and long- term investments, cash generated by our operations and available borrowing capacity under our new Credit Facility will be sufficient to fund our operations, expected capital expenditures, merger and acquisition activities and share repurchases for the foreseeable future. However, we plan to further expand our busi- ness; therefore, we may need to raise additional funds in the future through equity or debt financing, strategic relationships or other arrangements. Depending on future conditions in the capital and credit markets, we could encounter difficulty securing additional financ- ing in the type or amount necessary to pursue these objectives. Off-Balance Sheet Arrangements At September 30, 2012 and 2011, we did not have any unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or spe- cial purpose entities, which might have been estab- lished for the purpose of facilitating off-balance sheet arrangements. 30 Tabular Disclosure of Contractual Obligations The following summarizes our contractual obligations at September 30, 2012, and the effect such obligations are expected to have on our liquidity and cash flow in future periods. Contractual Obligations (In millions) Long-term debt Interest expense and fees on long-term debt Purchase obligations Operating leases Other long-term liabilities* Total contractual obligations Less Than 1 Year Total 1–3 Years 3–5 Years After 5 Years $172.8 $10.9 $26.3 $135.6 $ — 13.2 3.7 27.0 8.4 26.0 2.8 7.1 — 6.2 0.3 3.3 — 3.3 0.3 1.8 — — 0.4 0.5 7.1 $228.5 $43.4 $36.1 $141.0 $8.0 * We have excluded $2.0 million in deferred tax liabilities from the other long-term liability amounts presented as the deferred taxes that will be settled in cash are not known and the timing of any such payments is uncertain. Interest Expense and Fees on Long-Term Debt Interest payments on long-term debt reflect LIBOR- based floating rates in effect at September 30, 2012. Commitment fees are based on our estimated consoli- dated leverage ratio in future periods. See Note 9 of the Notes to the Consolidated Financial Statements for additional information regarding our long-term debt. Purchase Obligations We have entered into multi-year supply agreements with Cabot Corporation, our former parent company which is not a related party, for the purchase of certain fumed metal oxides. We purchase fumed silica primarily under a fumed silica supply agreement with Cabot Corporation that became effective in January 2004, and was amended in September 2006 and in April 2008, the latter of which extended the termination date of the agreement from December 2009 to December 2012 and also changed the pricing and some other non-material terms of the agreement to the benefit of both parties. We are generally obligated to purchase fumed silica for at least 90% of our six-month volume forecast for certain of our slurry products, to purchase certain minimum quantities every six months, and to pay for the shortfall if we purchase less than these amounts. We are cur- rently working with Cabot Corporation to negotiate the terms of a new fumed silica supply agreement that we anticipate would take effect following the expiration of the current agreement; however, the terms of the new agreement may be different from those in the current agreement. Since December 2001, we have purchased fumed alumina primarily under a fumed alumina supply agreement with Cabot Corporation that expired in December 2011. We are now operating under a renewed fumed alumina supply agreement with Cabot Corpora- tion, which expires in April 2013, under which we are obligated to pay certain fixed, capital and variable costs, and have certain take-or-pay obligations. We currently anticipate we will not have to pay any shortfall under these agreements. Under these agreements, Cabot Corporation continues to be our exclusive supplier of certain quantities and types of fumed silica and fumed alumina for certain products we produced as of the effective dates of these agreements. Subject to certain terms, Cabot Corporation is prohibited from selling certain types of fumed alumina to third parties for use in CMP applications, as well as engaging itself in CMP applications. If Cabot Corporation fails to supply us with our requirements for any reason, including if we require product specification changes that Cabot Corporation cannot meet, we have the right to purchase products meeting those specifications from other suppliers. We also may purchase fumed alumina and fumed silica from other suppliers for certain products, including those commercialized after certain dates related to these agreements and their amendments. Purchase obliga- tions include an aggregate amount of $9.0 million of contractual commitments related to our Cabot Corpora- tion agreements for fumed silica and fumed alumina. Operating Leases We lease certain vehicles, warehouse facilities, office space, machinery and equipment under cancelable and noncancelable operating leases, most of which expire within ten years of their respective commencement dates and may be renewed by us. Operating lease obli- gations also include certain costs associated with our pad finishing operation located at Taiwan Semiconductor Manufacturing Company, which are accounted for as operating lease payments. Other Long-Term Liabilities Other long-term liabilities at September 30, 2012 consist of liabilities related to our Japan retirement allowance, which represents approximately $5.7 million, our liability for future payments to be made under our Cabot Micro- electronics Supplemental Employee Retirement Plan and our liability for uncertain tax positions. 31 Item 7A. Quantitative and Qualitative Disclosures About Market Risk Effect of Currency Exchange Rates and Exchange Rate Risk Management We conduct business operations outside of the United States through our foreign operations. Some of our for- eign operations maintain their accounting records in their local currencies. Consequently, period to period comparability of results of operations is affected by fluctuations in exchange rates. The primary currencies to which we have exposure are the Japanese yen and the New Taiwan dollar. As noted in Item 7 of our Annual Report on Form 10-K for the fiscal year ended Septem- ber 30, 2011, the negative effects of foreign exchange rate changes, primarily related to the Japanese yen, accounted for a decrease in our full fiscal year 2011 gross profit percentage compared to full fiscal year 2010. From time to time we enter into forward contracts in an effort to manage foreign currency exchange exposure. However, we are unlikely to be able to hedge these exposures completely. During fiscal 2012, we recorded $6.9 million in currency translation gains, net of tax, that are included in other comprehensive income on our Consolidated Balance Sheet. These gains primarily relate to changes in the U.S. dollar value of assets and liabilities transacted in foreign currencies based on the general fluctuations of the U.S. dollar relative to the Japanese yen and the New Taiwan dollar. Approximately 13% of our revenue is transacted in currencies other than the U.S. dollar. However, we also incur expenses in foreign countries that are transacted in currencies other than the U.S. dollar, so the net exposure on the Consolidated Statement of Income is reduced. We do not currently enter into forward exchange contracts or other derivative instruments for speculative or trading purposes. Market Risk and Sensitivity Analysis Related to Foreign Exchange Rate Risk There was a significant weakening of the U.S. dollar against the Japanese yen during our fiscal years 2010 and 2011, which had some negative impact on our results of operations. We have performed a sensitivity analysis assuming a hypothetical additional 10% adverse movement in foreign exchange rates. As of September 30, 2012, the analysis demonstrated that such market movements would not have a material adverse effect on our consolidated financial position, results of operations or cash flows over a one-year period. Actual gains and losses in the future may differ materially from this analy- sis based on changes in the timing and amount of for- eign currency rate movements and our actual exposures. Interest Rate Risk At September 30, 2012, we have $172.8 million in long- term debt at variable interest rates. Assuming a hypo- thetical 100 basis point increase in our current variable interest rate, our interest expense would increase by approximately $0.4 million per quarter. Market Risk Related to Investments in Auction Rate Securities At September 30, 2012, we owned two auction rate securities (ARS) with a total estimated fair value of $8.0 million ($8.2 million par value) which were classified as other long-term assets on our Consolidated Balance Sheet. Beginning in 2008, general uncertainties in the global credit markets significantly reduced liquidity in the ARS market, and this illiquidity continues. For more information on our ARS, see “Risk Factors” set forth in Part I, Item 1A, “Critical Accounting Policies and Estimates” in MD&A in Part II, Item 7, and Notes 3 and 7 of the Notes to the Consolidated Financial Statements in Part II, Item 8 of this Annual Report on Form 10-K. 32 Item 8.

In addition, in our opinion, the financial statement schedule listed in the accompa- nying index presents fairly, in all material respects, the information set forth therein when read in conjunction with the related consolidated financial statements. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial report- ing as of September 30, 2012, based on criteria estab- lished in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company’s man- agement is responsible for these financial statements and financial statement schedule, for maintaining effec- tive internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in Management’s Report on Internal Control Over Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on these financial statements, on the financial statement schedule, and on the Company’s internal control over financial reporting based on our integrated audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of mate- rial misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included obtain- ing an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and oper- ating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions. A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external pur- poses in accordance with generally accepted account- ing principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reason- able detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) pro- vide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expendi- tures of the company are being made only in accor- dance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthor- ized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstate- ments. Also, projections of any evaluation of effective- ness to future periods are subject to the risk that controls may become inadequate because of changes in condi- tions, or that the degree of compliance with the policies or procedures may deteriorate.

Background and Basis of Presentation Cabot Microelectronics Corporation (“Cabot Microelec- tronics”, “the Company”, “us”, “we” or “our”) supplies high-performance polishing slurries and pads used in the manufacture of advanced integrated circuit (IC) devices within the semiconductor industry, in a process called chemical mechanical planarization (CMP). CMP polishes surfaces at an atomic level, thereby enabling IC device manufacturers to produce smaller, faster and more complex IC devices with fewer defects. We develop, produce and sell CMP slurries for polishing many of the conducting and insulating materials used in IC devices, and also for polishing the disk substrates and magnetic heads used in hard disk drives. We also develop, manufacture and sell CMP polishing pads, which are used in conjunction with slurries in the CMP process. We also pursue other demanding surface modification applications through our Engineered Surface Finishes (ESF) business where we believe we can leverage our expertise in CMP consumables for the semiconductor industry to develop products for demanding polishing applications in other industries. The audited consolidated financial statements have been prepared by us pursuant to the rules of the Secu- rities and Exchange Commission (SEC) and accounting principles generally accepted in the United States of America. We operate predominantly in one industry segment—the development, manufacture, and sale of CMP consumables. Reclassifications of prior period amounts have been made to separate interest expense from other income (expense) to conform to the current period presentation. Results of Operations The results of operations for the fiscal year ended September 30, 2012 include certain adjustments to cor- rect prior period amounts, which we have determined to be immaterial to the current period and the prior peri- ods to which they relate. These adjustments included the correction of historical tax accounting related to the acquisition of Epoch Material Co., Ltd. (Epoch) in fiscal 2009 and the correction of prior period remeasurement of certain foreign cash balances into their functional cur- rency amounts, which were recorded in the third quarter of fiscal 2012, and the correction of additional historical tax accounting recorded in the fourth quarter of fiscal 2012. The correction of tax accounting related to the Epoch acquisition resulted in additional income tax expense of $172 in the Consolidated Statement of Income and adjustments to the Consolidated Balance Sheet including: an increase of $2,172 in cumulative translation adjustment within accumulated other com- prehensive income (CTA); an increase of $1,712 in good- will; and a decrease of $288 in deferred tax liabilities. The correction of the historical remeasurement of cer- tain foreign cash balances resulted in $333 of additional expense ($222, net of tax) included in other income (expense) on the Consolidated Statement of Income. Additional tax accounting related corrections recorded in the fourth quarter resulted in additional income tax expense of $801 and adjustments to the Consolidated Balance Sheet including: a decrease of $1,104 in deferred tax liabilities; a decrease of $64 in deferred tax assets; a decrease of $891 in income tax receivable; and an increase of $950 in CTA. Collectively, these adjustments reduced net income for fiscal 2012 by $1,195 and diluted earnings per share by approximately $0.05. The results of operations for the fiscal year ended September 30, 2011 include certain adjustments to cor- rect prior period amounts, which we have determined to be immaterial to the current period and the prior peri- ods to which they relate. Adjustments in fiscal 2011 listed below related to: (1) $1,474 ($1,014, net of tax) in employer-paid fringe benefits for required contributions to our 401(k) Plan, Supplemental Employee Retirement Plan, and non-United States statutory pension plans as a result of our annual payment pursuant to our fiscal 2010 annual incentive cash bonus program (AIP); (2) income tax expense of $671 recorded for certain compensation in fiscal 2008 through 2010 for which a previous tax ben- efit should not have been recorded; (3) the reversal of a $497 deferred tax asset regarding certain share-based compensation expense which is not subject to such tax treatment; (4) our under-accrual of $290 ($199, net of tax) for payments made pursuant to the AIP as a result of the calculation of results against goals under the AIP; and (5) other immaterial corrections to deferred tax assets and liabilities that reduced our income tax expense by $101. Collectively, these adjustments reduced net income for fiscal 2011 by $2,280 and diluted earnings per share by approximately $0.10. 2. Summary of Significant Accounting Policies Principles of Consolidation The consolidated financial statements include the accounts of Cabot Microelectronics and its subsidiaries. All inter- company transactions and balances between the com- panies have been eliminated as of September 30, 2012. 39 Use of Estimates The preparation of financial statements and related dis- closures in conformity with accounting principles gener- ally accepted in the United States of America requires management to make judgments, assumptions and estimates that affect the amounts reported in the con- solidated financial statements and accompanying notes. The accounting estimates that require management’s most difficult and subjective judgments include, but are not limited to, those estimates related to bad debt expense, warranty obligations, inventory valuation, valu- ation and classification of auction rate securities, impair- ment of long-lived assets and investments, business combinations, goodwill, other intangible assets, share- based compensation, income taxes and contingencies. We base our estimates on historical experience, current conditions and on various other assumptions that we believe are reasonable under the circumstances. However, future events are subject to change and esti- mates and judgments routinely require adjustment. Actual results may differ from these estimates under different assumptions or conditions. Cash, Cash Equivalents and Short-Term Investments We consider investments in all highly liquid financial instruments with original maturities of three months or less to be cash equivalents. Short-term investments include securities generally having maturities of 90 days to one year. We did not own any securities that were considered short-term as of September 30, 2012 or 2011. See Note 3 for a more detailed discussion of other finan- cial instruments. Accounts Receivable and Allowance for Doubtful Accounts Trade accounts receivable are recorded at the invoiced amount and do not bear interest. We maintain an allow- ance for doubtful accounts for estimated losses result- ing from the potential inability of our customers to make required payments. Our allowance for doubtful accounts is based on historical collection experience, adjusted for any specific known conditions or circumstances such as customer bankruptcies and increased risk due to eco- nomic conditions. Uncollectible account balances are charged against the allowance when we believe that it is probable that the receivable will not be recovered. Accounts receivable, net of allowances for doubtful accounts, was $53,506 as of September 30, 2012 and $52,747 as of September 30, 2011. The increase was pri- marily due to the increase in revenue recorded in the fourth quarter of fiscal 2012 as compared to the fourth quarter of fiscal 2011, partially offset by an increase in the allowance for doubtful accounts. The increase in the allowance for doubtful accounts was primarily related to $3,727 in bad debt expense recorded in the second quarter of fiscal 2012 for Elpida Memory, Inc. (Elpida), a significant customer in Japan that filed for bankruptcy protection in February 2012. Amounts charged to expense are recorded in general and administrative expenses. Elpida owed the Company $3,727 in accounts receivable for shipments made prior to its bankruptcy filing. To our understanding, Elpida’s bankruptcy plan has not been formally approved, and collection of any or all of this balance remains uncertain. Consequently, we have maintained a reserve for the entire balance. Elpida has been paying the Company on a current basis for all shipments made subsequent to its bankruptcy filing. The Elpida receivable is denominated in Japanese yen, so it is subject to foreign exchange fluctuations which are included in the table below under the deductions and adjustments. Our allowance for doubtful accounts changed during the fiscal year ended September 30, 2012 as follows: Balance as of September 30, 2011 Amounts charged to expense Deductions and adjustments Balance as of September 30, 2012 $ 1,090 3,771 (104) $ 4,757 See Schedule II under Part IV, Item 15 of this Form 10-K for more information on our allowance for doubtful accounts. Concentration of Credit Risk Financial instruments that subject us to concentrations of credit risk consist principally of accounts receivable. We perform ongoing credit evaluations of our customers’ financial conditions and generally do not require collateral to secure accounts receivable. Our exposure to credit risk associated with nonpayment is affected principally by conditions or occurrences within the semiconductor industry and global economy. Prior to the one situation in fiscal 2012, we had not experienced significant losses relating to accounts receivable from individual customers or groups of customers. Customers who represented more than 10% of revenue are as follows: Year Ended September 30, 2012 2011 2010 18% 17% 13% 10% 18% * * * 11% Taiwan Semiconductor Manufacturing Co. (TSMC) Samsung United Microelectronics Corporation (UMC) *Denotes less than ten percent of total 40 TSMC accounted for 17.1% and 12.9% of net accounts receivable at September 30, 2012 and 2011, respec- tively. Samsung accounted for 12.1% and 11.4% of net accounts receivable at September 30, 2012 and 2011, respectively. Fair Values of Financial Instruments The recorded amounts of cash, accounts receivable, and accounts payable approximate their fair values due to their short-term, highly liquid characteristics. The fair value of our long-term auction rate securities (ARS) is determined through discounted cash flow analyses. See Note 3 for a more detailed discussion of the fair value of financial instruments. Inventories Inventories are stated at the lower of cost, determined on the first-in, first-out (FIFO) basis, or market. Finished goods and work in process inventories include material, labor and manufacturing overhead costs. We regularly review and write down the value of inventory as required for estimated obsolescence or unmarketability. An inven- tory reserve is maintained based upon a historical per- centage of actual inventories written off and applied against inventory value at the end of the period, adjusted for known conditions and circumstances. Property, Plant and Equipment Property, plant and equipment are recorded at cost. Depreciation is based on the following estimated useful lives of the assets using the straight-line method: Buildings Machinery and equipment Furniture and fixtures Information systems Assets under capital leases 15–25 years 3–10 years 5–10 years 3–5 years Term of lease or estimated useful life Expenditures for repairs and maintenance are charged to expense as incurred. Expenditures for major renewals and betterments are capitalized and depreciated over the remaining useful lives. As assets are retired or sold, the related cost and accumulated depreciation are removed from the accounts and any resulting gain or loss is included in the results of operations. We capital- ize the costs related to the design and development of software used for internal purposes. Impairment of Long-Lived Assets Reviews are regularly performed to determine whether facts and circumstances exist that indicate the carrying amount of assets may not be recoverable or the useful life is shorter than originally estimated. Asset recover- ability assessment begins by comparing the projected undiscounted cash flows associated with the related asset or group of assets over their remaining lives against their respective carrying amounts. Impairment, if any, is based on the excess of the carrying amount over the fair value of those assets. If assets are deter- mined to be recoverable, but their useful lives are shorter than originally estimated, the net book value of the asset is depreciated over the newly determined remaining useful life. Goodwill and Intangible Assets We amortize intangible assets with finite lives over their estimated useful lives, which range from one to ten and one-half years. Intangible assets with finite lives are reviewed for impairment using a process similar to that used to evaluate other long-lived assets. Goodwill and indefinite-lived intangible assets are not amortized and are tested annually in the fourth fiscal quarter or more frequently if indicators of potential impairment exist, using a fair-value-based approach. The recoverability of goodwill is measured at the reporting unit level, which is defined as either an operating segment or one level below an operating segment, referred to as a compo- nent. A component is a reporting unit when the compo- nent constitutes a business for which discreet financial information is available and segment management reg- ularly reviews the operating results of the component. Components may be combined into one reporting unit when they have similar economic characteristics. We had three reporting units to which we allocated good- will and intangible assets as of September 30, 2012. Goodwill impairment testing requires a comparison of the fair value of each reporting unit to the carrying value. If the carrying value exceeds fair value, goodwill is considered impaired. The amount of the impairment is the difference between the carrying value of goodwill and the “implied” fair value. The fair value of the report- ing unit may be determined using a discounted cash flow analysis of our projected future results. As dis- cussed later in this Note 2 under the heading “Effects of Recent Accounting Pronouncements”, an entity now has the option to assess qualitative factors to determine if the two-step impairment test must be performed. We elected this option in both fiscal 2012 and 2011 when we performed our annual impairment review of goodwill. As also discussed under “Effects of Recent Accounting Pronouncements”, an entity now has the option to assess qualitative factors in its impairment review of indefinite-lived intangible assets. We elected this option in fiscal 2012 when we performed our impairment review of our indefinite-lived intangible assets. We determined that goodwill and other intangible assets were not impaired as of September 30, 2012. 41 Warranty Reserve We maintain a warranty reserve that reflects manage- ment’s best estimate of the cost to replace product that does not meet customers’ specifications and per- formance requirements. The warranty reserve is based upon a historical product return rate, adjusted for any specific known conditions or circumstances. Adjust- ments to the warranty reserve are recorded in cost of goods sold. Foreign Currency Translation Certain operating activities in Asia and Europe are denominated in local currency, considered to be the functional currency. Assets and liabilities of these oper- ations are translated using exchange rates in effect at the end of the year, and revenue and costs are trans- lated using weighted-average exchange rates for the year. The related translation adjustments are reported in comprehensive income in stockholders’ equity. Foreign Exchange Management We transact business in various foreign currencies, pri- marily the Japanese yen and New Taiwan dollar. Our exposure to foreign currency exchange risks has not been significant because a large portion of our business is denominated in U.S. dollars. However, there was a significant weakening of the U.S. dollar against the Japanese yen during our fiscal years 2010 and 2011, which had some negative impact on our results of oper- ations. As noted in our Annual Report on Form 10-K for the fiscal year ended September 30, 2011, the negative effects of foreign exchange rate changes, primarily related to the Japanese yen, accounted for an approxi- mate 1.5 percentage point decline in our gross profit margin in fiscal 2011 compared to fiscal 2010. Periodically we enter into forward foreign exchange contracts in an effort to mitigate the risks associated with currency fluc- tuations on certain foreign currency balance sheet exposures. Our foreign exchange contracts do not qual- ify for hedge accounting under the accounting rules for derivative instruments. See Note 10 for a more detailed discussion of derivative financial instruments. Intercompany Loan Accounting We maintain intercompany loan agreements with our wholly-owned subsidiary, Nihon Cabot Microelectronics K.K. (“the K.K.”), under which we provided funds to the K.K. to finance the purchase of certain assets from our former Japanese branch at the time of the establish- ment of this subsidiary, for the purchase of land adja- cent to our Geino, Japan, facility, for the construction of our Asia Pacific technology center, and for the purchase of a 300 millimeter polishing tool and related metrology equipment, all of which are part of the K.K., as well as for general business purposes. Since settlement of the notes is expected in the foreseeable future, and our subsidiary has been consistently making timely pay- ments on the loans, the loans are considered foreign- currency transactions. Therefore the associated foreign exchange gains and losses are recognized as other income or expense rather than being deferred in the cumulative translation account in other comprehen- sive income. We also maintain intercompany loan agreements between some of our wholly-owned foreign subsidiaries, includ- ing Cabot Microelectronics Singapore Pte. Ltd., Epoch Material Co., Ltd. in Taiwan and Hanguk Cabot Micro- electronics, LLC in South Korea. These loans have pro- vided funds for the construction and operation of our research, development and manufacturing facility in South Korea. These loans are also considered foreign currency transactions and are accounted for in the same manner as our intercompany loans to the K.K. Purchase Commitments We have entered into unconditional purchase obliga- tions, which include noncancelable purchase commit- ments and take-or-pay arrangements with suppliers. We review our agreements and make an assessment of the likelihood of a shortfall in purchases and determine if it is necessary to record a liability. Revenue Recognition Revenue from CMP consumable products is recognized when title is transferred to the customer, provided acceptance and collectability are reasonably assured. Title transfer generally occurs upon shipment to the customer or when inventory held on consignment is consumed by the customer, subject to the terms and conditions of the particular customer arrangement. We have consignment agreements with a number of our customers that require, at a minimum, monthly con- sumption reports that enable us to record revenue and inventory usage in the appropriate period. We market our products through distributors in a few areas of the world. We recognize revenue upon ship- ment and when title is transferred to the distributor. We do not have any arrangements with distributors that include payment terms, rights of return, or rights of exchange outside the normal course of business, or any other significant matters that would impact the timing of revenue recognition. 42 Within our Engineered Surface Finishes (ESF) business, sales of equipment are recorded as revenue upon deliv- ery and customer acceptance. Amounts allocated to installation and training are deferred until those services are provided and are not material. Revenues are reported net of any value-added tax or other such tax assessed by a governmental authority on our revenue-producing activities. Shipping and Handling Costs related to shipping and handling are included in cost of goods sold. Research, Development and Technical Research, development and technical costs are expensed as incurred and consist primarily of staffing costs, materials and supplies, depreciation, utilities and other facilities costs. Income Taxes Current income taxes are determined based on esti- mated taxes payable or refundable on tax returns for the current year. Deferred income taxes are determined using enacted tax rates for the effect of temporary differences between the book and tax bases of recorded assets and liabilities. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Provisions are made for both U.S. and any foreign deferred income tax liability or benefit. We recognize the tax benefit of an uncertain tax position only if it is more likely than not that the tax position will be sus- tained by the taxing authorities, based on the technical merits of the position. In fiscal 2012, 2011 and 2010, we elected to permanently reinvest the earnings of certain of our foreign subsidiaries outside the U.S. rather than repatriating the earnings to the U.S. See Note 15 for additional information on income taxes. Share-Based Compensation We record share-based compensation expense for all share-based awards, including stock option grants, restricted stock and restricted stock unit awards and employee stock purchases. We calculate share-based compensation expense using the straight-line approach based on awards ultimately expected to vest, which requires the use of an estimated forfeiture rate. Our estimated forfeiture rate is primarily based on historical experience, but may be revised in future periods if actual forfeitures differ from the estimate. We use the Black-Scholes option-pricing model to estimate the grant date fair value of our stock options and employee stock purchase plan purchases. This model requires the input of highly subjective assumptions, including the price volatility of the underlying stock, the expected term of our stock options and the risk-free interest rate. We estimate the expected volatility of our stock options based on a combination of our stock’s historical volatil- ity and the implied volatilities from actively-traded options on our stock. Prior to fiscal 2012, we calculated the expected term of our stock options using the simpli- fied method, due to our limited amount of historical option exercise data, and we added a slight premium to this expected term for employees who meet the defini- tion of retirement eligible pursuant to their grants dur- ing the contractual term of the grant. The simplified method uses an average of the vesting term and the contractual term of the option to calculate the expected term. We experienced a significant increase in the vol- ume of stock option exercises in fiscal 2011. Conse- quently, we used this exercise data, as well as historical exercise data, to calculate the expected term of our stock options granted in fiscal 2012, rather than using the simplified method, and we continued to add a slight premium for employees who meet the definition of retirement eligible under their grant terms. The expected term we calculated using option exercise his- tory was within 1% of the expected term calculated under the simplified method. The risk-free rate is derived from the U.S. Treasury yield curve in effect at the time of grant. The fair value of our restricted stock and restricted stock unit awards represents the closing price of our common stock on the date of award. For additional information regarding our share-based compensation plans, refer to Note 11. Earnings Per Share Basic earnings per share (EPS) is calculated by dividing net income available to common stockholders by the weighted-average number of common shares outstand- ing during the period. Diluted EPS is calculated by using the weighted-average number of common shares outstanding during the period increased to include the weighted-average dilutive effect of “in-the-money” stock options and unvested restricted stock shares using the treasury stock method. Comprehensive Income Comprehensive income primarily differs from net income due to foreign currency translation adjustments. 43 Effects of Recent Accounting Pronouncements In May 2011, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2011-04, “Fair Value Measurement (Topic 820)—Amend- ments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs” (ASU 2011-04). The amendments in ASU 2011-04 change some of the wording used to describe certain U.S. GAAP requirements for measuring fair value and disclosing information about fair value measurements. Some of the amendments clarify the FASB’s intent about the appli- cation of existing fair value measurement requirements and other amendments change a particular principle or requirement for measuring fair value or for disclosing information about fair value measurements. ASU 2011- 04 is effective for interim and annual periods begin- ning after December 15, 2011. The adoption of ASU 2011-04 did not have a material impact on the fair value measurements and their related disclosures in our financial statements. In June 2011, the FASB issued ASU No. 2011-05, “Comprehensive Income (Topic 220)—Presentation of Comprehensive Income” (ASU 2011-05). The provisions of ASU 2011-05 require an entity to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehen- sive income or in two separate but consecutive state- ments. If two separate statements are presented, the statement of other comprehensive income should immediately follow the statement of net income. ASU 2011-05 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2011. Early adoption of these provisions is permitted and will be applied retrospectively. The adoption of ASU 2011- 05 will change the way we present comprehensive income as current U.S. GAAP permits an annual presen- tation of comprehensive income within the statement of equity and quarterly presentation of comprehensive income within the footnotes to the financial statements. We expect to present comprehensive income in a sepa- rate statement immediately following the statement of net income beginning in our fiscal quarter ending December 31, 2012. In September 2011, the FASB issued ASU No. 2011-08, “Intangibles-Goodwill and Other (Topic 350)—Testing Goodwill for Impairment” (ASU 2011-08). The provisions of ASU 2011-08 provide an entity with the option to assess qualitative factors to determine whether the exis- tence of events or circumstances leads to the determi- nation that it is more-likely-than-not that the fair value of a reporting unit is less than its carrying amount. This qualitative assessment is referred to as a “step zero” approach. If, based on the review of the qualitative fac- tors, an entity determines it is not more-likely-than-not that the fair value of a reporting unit is less than its car- rying value, the entity may skip the two-step impairment test required by prior accounting guidance. If an entity determines otherwise, the first step (“step one”) of the two-step impairment test is required. This new account- ing guidance also gives the entity the option to bypass “step zero” and proceed directly to “step one”; an entity may resume performing “step zero” in any subsequent period. ASU 2011-08 is effective for fiscal years begin- ning after December 15, 2011, with early adoption per- mitted if the financial statements for the most recent annual or interim period have not yet been issued. We chose to early adopt these new accounting provisions effective with our goodwill impairment review during the fourth quarter of fiscal 2011. We determined, based upon our qualitative assessment, that “step one” was not required as there were no indications that the fair value of our reporting units was less than the carrying value. See Note 6 for a more detailed discussion of our goodwill and intangible assets. In December 2011, the FASB issued ASU No. 2011-12, “Comprehensive Income (Topic 220)—Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in ASU 2011-05” (ASU 2011-12). The provisions of ASU 2011-12 supersede the require- ment of ASU 2011-05 to present the effect of reclas- sification adjustments on the face of the financial statements where net income is presented, by compo- nent of net income, and on the face of the financial statements where other comprehensive income is pre- sented, by component of other comprehensive income. ASU 2011-12 is effective for fiscal years, and interim peri- ods within those years, beginning after December 15, 2011. We do not expect the adoption of ASU 2011-12 will have a material effect on our financial statements as we do not expect material reclassification adjustments out of accumulated other comprehensive income. In July 2012, the FASB issued ASU No. 2012- 02, “Intangibles-Goodwill and Other (Topic) 350)—Testing Indefinite-Lived Intangible Assets for Impairment” (ASU 2012-02). The provisions of ASU 2012-20 provide an entity with the option to assess qualitative factors to deter- mine whether it is more-likely-than-not that the fair value of an indefinite-lived intangible asset is less than its carrying value. If, based on the review of the qualitative factors, an entity determines it is not more-likely-than-not that 44 the fair value of an indefinite-lived intangible asset is less than its carrying value, no further action is required. If an entity determines otherwise, then it is required to determine the fair value of the indefinite-lived intan- gible asset and perform the quantitative impairment test required by prior accounting guidance. Similar to under ASU 2011-08, the entity has the option to bypass the qualitative assessment and proceed directly to the fair value calculation and the entity may resume per- forming the qualitative analysis in any subsequent period. ASU 2012-02 is effective for fiscal years begin- ning after September 15, 2012, with early adoption per- mitted if the financial statements for the most recent annual or interim period have not yet been issued. We chose to early adopt these new accounting provi- sions effective with our goodwill impairment review during the fourth quarter of fiscal 2012. We determined, based upon our qualitative assessment, that the fair value calculation was not required as there were no indications that the fair value of our indefinite-lived intangible assets was less than their carrying value. See Note 6 for a more detailed discussion of our goodwill and intangible assets. 3. Fair Value of Financial Instruments Fair value is defined as the price that would be received from the sale of an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The FASB established a three-level hierarchy for disclosure based on the extent and level of judgment used to esti- mate fair value. Level 1 inputs consist of valuations based on quoted market prices in active markets for identical assets or liabilities. Level 2 inputs consist of valuations based on quoted prices for similar assets or liabilities, quoted prices for identical assets or liabilities in an inactive market, or other observable inputs. Level 3 inputs consist of valuations based on unobservable inputs that are supported by little or no market activity. The following tables present financial assets that we measured at fair value on a recurring basis at September 30, 2012 and 2011. As permitted under the relevant stan- dards, we have chosen to not measure any of our liabili- ties at fair value as we believe our liabilities approximate their fair value due to their short-term, highly liquid characteristics. We have classified the following assets in accordance with the fair value hierarchy set forth in the applicable standards. In instances where the inputs used to measure the fair value of an asset fall into more than one level of the hierarchy, we have classified them based on the lowest level input that is significant to the determination of the fair value. September 30, 2012 Level 1 Level 2 Level 3 Total Fair Value Cash and cash equivalents Auction rate securities (ARS) Other long-term investments $ 178,459 $— $ — $ 178,459 — 1,082 — — 7,991 7,991 — 1,082 Total $ 179,541 $— $ 7,991 $ 187,532 September 30, 2011 Level 1 Level 2 Level 3 Total Fair Value Cash and cash equivalents Auction rate securities (ARS) Other long-term investments $ 302,546 $— $ — $ 302,546 — 827 — — 8,041 8,041 — 827 Total $ 303,373 $— $ 8,041 $ 311,414 Our cash and cash equivalents consist of various bank accounts used to support our operations and invest- ments in institutional money-market funds which are traded in active markets. The ARS and other long-term investments are included in other long-term assets on our Consolidated Balance Sheet. The fair value of our long-term ARS is determined through two discounted cash flow analyses, one using a discount rate based on a market index comprised of tax exempt variable rate demand obligations and one using a discount rate based on the LIBOR swap curve, adding a risk factor to reflect current liquidity issues in the ARS market. Our other long-term investments represent the fair value of investments under the Cabot Microelec tronics Supplemental Employee Retirement Plan (SERP), which is a nonqualified supplemental savings plan. The fair value of the investments is determined through quoted market prices within actively traded markets. Although the investments are allocated to individual participants and investment decisions are made solely by those par- ticipants, the SERP has been deemed a nonqualified plan. Consequently, the Company owns the assets and the related liability for disbursement until such time a participant makes a qualifying withdrawal. The long- term asset and long-term liability were adjusted to $1,082 in the fourth quarter of fiscal 2012 to reflect their fair value as of September 30, 2012. We applied accounting standards regarding the classifi- cation and valuation of financial instruments to the valu- ation of our investment in ARS at September 30, 2012 45 and 2011. Our ARS investments at September 30, 2012 consisted of two tax exempt municipal debt securities with a total par value of $8,225. The ARS market began to experience illiquidity in early 2008, and this illiquidity continues. Despite this lack of liquidity, there have been no defaults of the underlying securities and interest income on these holdings continues to be received on scheduled interest payment dates. Our ARS, when pur- chased, were generally issued by A-rated municipalities. Although the credit ratings of both municipalities have been downgraded since our original investment, the ARS are credit enhanced with bond insurance and cur- rently carry a credit rating of AA- by Standard and Poors. Since an active market for ARS does not currently exist, we determine the fair value of these investments using a Level 3 discounted cash flow analysis and also consider other factors such as the reduced liquidity in the ARS market and nature of the insurance backing. Key inputs to our discounted cash flow model include projected cash flows from interest and principal payments and the weighted probabilities of improved liquidity or debt refinancing by the issuer. We also incorporate certain Level 2 market indices into the discounted cash flow analysis, including published rates such as the LIBOR rate, the LIBOR swap curve and a municipal swap index published by the Securities Industry and Financial Markets Association. The following table presents a rec- onciliation of the activity in fiscal 2012 for fair value mea- surements using level 3 inputs: Balance as of September 30, 2011 Net sales of ARS Balance as of September 30, 2012 $ 8,041 (50) $ 7,991 Based on our fair value assessment, we determined that one ARS continues to be impaired as of September 30, 2012. This security has a fair value of $3,041 (par value $3,275). We assessed the impairment in accordance with the applicable standards and determined that the impairment was due to the lack of liquidity in the ARS market rather than to credit risk. We have maintained the $234 temporary impairment that we previously recorded. We believe that this ARS is not permanently impaired because in the event of default by the issuer, we expect the insurance provider would pay interest and principal following the original repayment schedule, we successfully monetized at par value $50 of this secu- rity during our fiscal quarter ended March 31, 2012 and we do not intend to sell the security nor do we believe we will be required to sell the security before the value recovers, which may be at maturity. We determined that the fair value of the other ARS was not impaired as of September 30, 2012. In November 2011, the municipality that issued our impaired ARS filed for bankruptcy pro- tection. We considered these developments, in light of the continued insurance backing, and have concluded the impairment we have maintained remains adequate and temporary. See Note 7 for more information on these investments. 4. Inventories Inventories consisted of the following: Raw materials Work in process Finished goods Total September 30, 2012 2011 $ 34,591 6,333 25,548 $ 26,217 4,964 24,947 $ 66,472 $ 56,128 The increase in our inventory balance at September 30, 2012 was primarily due to raw material purchases made for business continuity purposes as we negotiate the terms of a new supply agreement with an existing sup- plier to replace the current agreement, which will expire at the end of December 2012. 5. Property, Plant and Equipment Property, plant and equipment consisted of the following: Land Buildings Machinery and equipment Furniture and fixtures Information systems Capital leases Construction in progress Total property, plant and equipment September 30, 2012 2011 $ 21,566 101,627 181,117 6,417 25,346 66 4,890 $ 21,597 100,779 171,595 6,247 23,318 9,820 5,166 341,029 338,522 Less: accumulated depreciation and amortization of assets under capital leases (216,009) (207,731) Net property, plant and equipment $ 125,020 $ 130,791 Depreciation expense, including amortization of assets recorded under capital leases, was $20,863, $21,271 and $22,568 for the years ended September 30, 2012, 2011 and 2010, respectively. In fiscal 2012, we recorded $968 in impairment expense primarily related to the decision to write-off certain operational assets at one of our foreign locations in accordance with the applicable accounting standards for the impairment and disposal of long-lived assets. Of this amount, $842 and $126 was included in cost of goods sold and selling and marketing expense, respec- tively. Impairment expense for fiscal 2011 and 2010 was not material. 46 6. Goodwill and Other Intangible Assets Goodwill was $44,620 and $41,148 as of September 30, 2012 and 2011, respectively. The increase in goodwill was due to a $1,712 correction discussed in Note 1, related to the calculation of foreign deferred tax lia- bilities associated with our fiscal 2009 acquisition of Epoch, and to $1,760 in foreign exchange fluctuations of the New Taiwan dollar. The components of other intangible assets are as follows: September 30, 2012 September 30, 2011 Gross Carrying Amount Accumulated Amortization Gross Carrying Amount Accumulated Amortization Other intangible assets subject to amortization: Product technology Acquired patents and licenses Trade secrets and know-how Customer relationships, distribution rights and other Total other intangible assets subject to amortization Total other intangible assets not subject to amortization* Total other intangible assets $ 8,387 8,270 2,550 12,586 31,793 1,190 $32,983 $ 4,902 6,775 2,550 6,283 20,510 $20,510 $ 8,266 8,115 2,550 12,154 31,085 1,190 $32,275 $ 3,890 6,446 2,550 4,738 17,624 $17,624 * Total other intangible assets not subject to amortization primarily consist of trade names. In fiscal 2012, we acquired $155 in other intangible assets, and other intangible assets increased by $553 due to foreign exchange fluctuations of the New Taiwan dollar. In fiscal 2011, other intangible assets increased by $275 due to foreign exchange fluctuations of the New Taiwan dollar. Goodwill and indefinite-lived intangible assets are tested for impairment annually in the fourth fiscal quar- ter or more frequently if indicators of potential impair- ment exist, using a fair-value-based approach. The recoverability of goodwill is measured at the reporting unit level, which is defined as either an operating seg- ment or one level below an operating segment. We have consistently determined the fair value of our reporting units using a discounted cash flow analysis (“step one”) of our projected future results. As dis- cussed in Note 2 under the heading “Effects of Recent Accounting Pronouncements”, effective September 30, 2011, we adopted new accounting pronouncements related to our goodwill impairment analysis, which allows an entity to perform a “step zero” assessment of the fair value of their reporting units. We used this new guidance in our annual impairment analysis for goodwill in both fiscal 2012 and 2011. As also discussed in Note 2, in fiscal 2012, we adopted new accounting pronounce- ments related to our impairment review of indefinite- lived intangible assets, which allows a qualitative assessment of factors used in the impairment review. Changes in economic and operating conditions that occur after the annual impairment analysis or an interim impairment analysis that impact our assumptions may result in future impairment charges. As a result of the review performed in the fourth quarter of fiscal 2012, we determined that there was no impairment of our good- will and intangible assets as of September 30, 2012. Amortization expense was $2,682, $2,720 and $2,426 for fiscal 2012, 2011 and 2010, respectively. Estimated future amortization expense for the five succeeding fiscal years is as follows: Fiscal Year 2013 2014 2015 2016 2017 Estimated Amortization Expense $2,637 2,510 2,442 2,020 1,187 7. Other Long-Term Assets Other long-term assets consisted of the following: Auction rate securities Other long-term assets Other long-term investments Total September 30, 2012 2011 $ 7,991 2,872 1,082 $ 8,041 1,504 827 $ 11,945 $ 10,372 As discussed in Note 3 of this Form 10-K, the two ARS that we owned as of September 30, 2012 are classified as long-term investments. The securities are credit enhanced with bond insurance to an AA- credit rating and all interest payments continue to be received on a timely basis. Although we believe these securities will ultimately be collected in full, we believe that it is not likely that we will be able to monetize the securities in 47 our next business cycle (which for us is generally one year). We maintain a $234 pretax reduction ($151 net of tax) in fair value on one of the ARS that we first recog- nized in fiscal 2008. We continue to believe this decline in fair value is temporary based on: (1) the nature of the underlying debt; (2) the presence of bond insurance; (3) the fact that all interest payments have been received; (4) our successful monetization of $50 of this ARS during the quarter ended March 31, 2012; and (5) our intention not to sell the security nor be required to sell the secu- rity until the value recovers, which may be at maturity, given our current cash position, our expected future cash flow, and our unused debt capacity. As discussed in Note 3 of this Form 10-K, we recorded a long-term asset and a corresponding long-term liability of $1,082 representing the fair value of our SERP invest- ments as of September 30, 2012. 8. Accrued Expenses, Income Taxes Payable and Other Current Liabilities Accrued expenses, income taxes payable and other cur- rent liabilities consisted of the following: Accrued compensation Goods and services received, not yet invoiced Deferred revenue and customer advances Warranty accrual Income taxes payable Taxes, other than income taxes Other Total September 30, 2012 2011 $ 18,532 $ 23,922 3,478 3,457 3,341 359 2,843 1,041 3,144 2,420 384 — 808 2,113 $ 32,738 $ 33,104 The decrease in accrued compensation was primarily due to the payment of our AIP earned in fiscal 2011, partially offset by the accrual of our AIP related to fiscal 2012. The income taxes payable represents amounts payable in foreign tax jurisdictions, which are presented gross of the income tax receivable amounts due from U.S. tax jurisdictions as of September 30, 2012. 9. Debt On February 13, 2012, we entered into a credit agree- ment (the “Credit Agreement”) among the Company, as Borrower, Bank of America, N.A., as administrative agent, swing line lender and an L/C issuer, Bank of America Merrill Lynch and J.P. Morgan Securities LLC, as joint lead arrangers and joint book managers, JPMorgan Chase Bank, N.A., as syndication agent, and Wells Fargo Bank, N.A. as documentation agent. The Credit Agreement provided us with a $175,000 term loan (the “Term Loan”), which we drew on February 27, 2012 to fund approximately half of the special cash dividend we paid to our stockholders on March 1, 2012, and a $100,000 revolving credit facility (the “Revolving Credit Facility”), which remains undrawn, with sub-limits for multicurrency borrowings, letters of credit and swing- line loans. The Term Loan and the Revolving Credit Facility are referred to as the “Credit Facilities”. The Credit Agreement provides for an uncommitted accor- dion feature that allows us to request the existing lend- ers or, if necessary, third-party financial institutions to provide additional capacity in the Revolving Credit Facility, in an amount not to exceed $75,000. The Term Loan has periodic scheduled principal repayments; however, we may prepay the loan without penalty. The Credit Facilities are scheduled to expire on February 13, 2017. In connection with the Credit Agreement, the Company simultaneously terminated its previously exist- ing $50,000 unsecured revolving credit facility, which had no outstanding balance at the time of termination. Borrowings under the Credit Facilities (other than in respect of swing-line loans) bear interest at a rate per annum equal to the “Applicable Rate” (as defined below) plus, at our option, either (1) a LIBOR rate deter- mined by reference to the cost of funds for deposits in the relevant currency for the interest period relevant to such borrowing or (2) the “Base Rate”, which is the high- est of (x) the prime rate of Bank of America, N.A., (y) the federal funds rate plus 1/2 of 1.00% and (z) the one- month LIBOR rate plus 1.00%. The initial Applicable Rate for borrowings under the Credit Facilities was 1.75% with respect to LIBOR borrowings and 0.25% with respect to Base Rate borrowings, with such Applicable Rate subject to adjustment based on our consolidated leverage ratio. Swing-line loans will bear interest at the Base Rate plus the Applicable Rate for Base Rate loans under the Revolving Credit Facility. In addition to paying interest on outstanding principal under the Credit Agreement, we will pay a commitment fee to the lend- ers under the Revolving Credit Facility in respect of the unutilized commitments thereunder at a rate ranging from 0.25% to 0.35%, based on our consolidated lever- age ratio. Interest expense and commitment fees are paid according to the relevant interest period and no less frequently than at the end of each calendar quarter. We paid $2,658 in customary arrangement fees, upfront fees and administration fees, of which $537 and $1,800 remains in prepaid expenses and other current assets and other long-term assets, respectively, on our Consolidated Balance Sheet as of September 30, 2012. 48 We must also pay letter of credit fees as necessary. We may voluntarily prepay the Credit Facilities without pre- mium or penalty, subject to customary “breakage” fees and reemployment costs in the case of LIBOR borrow- ings. All obligations under the Credit Agreement are guaranteed by each of our existing and future direct and indirect domestic subsidiaries (the “Guarantors”). The obligations under the Credit Agreement and guar- antees of those obligations are secured, subject to certain exceptions, by first priority liens and security interests in the assets of the Company and its domestic subsidiaries. The Credit Agreement contains covenants that restrict the ability of the Company and its subsidiaries to take certain actions, including, among other things and sub- ject to certain significant exceptions: creating liens, incurring indebtedness, making investments, engaging in mergers, selling property, paying dividends or amending organizational documents. The Credit Agree- ment requires us to comply with certain financial ratio maintenance covenants, including a maximum consoli- dated leverage ratio of 3.00 to 1.00 through June 30, 2013 and a minimum consolidated fixed charge cover- age ratio of 1.25 to 1.00. As of September 30, 2012, our consolidated leverage ratio was 1.60 to 1.00 and our consolidated fixed charge coverage ratio was 10.93 to 1.00. The Credit Agreement also contains customary affirmative covenants and events of default. We believe we are in compliance with these covenants. At September 30, 2012, we believe the fair value of the Term Loan approximates its carrying value of $172,812 as the loan bears a floating market rate of interest. As of September 30, 2012, $10,937 of the debt outstanding is classified as short term. As of September 30, 2012, scheduled principal repay- ments of the Term Loan were as follows: Fiscal Year 2013 2014 2015 2016 2017 Total Principal Repayments $ 10,937 10,938 15,312 21,875 113,750 $172,812 10. Derivative Financial Instruments Periodically we enter into forward foreign exchange contracts in an effort to mitigate the risks associated with currency fluctuations on certain foreign currency balance sheet exposures. Our foreign exchange con- tracts do not qualify for hedge accounting; therefore, the gains and losses resulting from the impact of cur- rency exchange rate movements on our forward foreign exchange contracts are recognized as other income or expense in the accompanying consolidated income statements in the period in which the exchange rates change. We do not use derivative financial instruments for trading or speculative purposes. In addition, all derivatives, whether designated in hedging relation- ships or not, are required to be recorded on the balance sheet at fair value. At September 30, 2012, we had one forward foreign exchange contract selling Japanese Yen related to intercompany notes with one of our subsidiaries in Japan and for the purpose of hedging the risk associated with a net transactional exposure in Japanese Yen. The fair value of our derivative instrument included in the Consolidated Balance Sheet, which was determined using Level 2 inputs, was as follows: Derivatives Not Designated as Hedging Instruments Foreign exchange contracts Balance Sheet Location Prepaid expenses and other current assets Accrued expenses and other current liabilities Asset Derivatives Liability Derivatives Fair Value at September 30, 2012 Fair Value at September 30, 2011 Fair Value at September 30, 2012 Fair Value at September 30, 2011 $38 $ — $48 $— $— $— $— $— The following table summarizes the effect of our derivative instrument on our Consolidated Statement of Income for the fiscal years ended September 30, 2012, 2011 and 2010: Gain (Loss) Recognized in Statement of Income Fiscal Year Ended Derivatives Not Designated as Hedging Instruments Statement of Income Location September 30, 2012 September 30, 2011 September 30, 2010 Foreign exchange contracts Other income (expense), net $154 $(806) $(555) 49 11. Share-Based Compensation Plans Equity Incentive Plan and Omnibus Incentive Plan In March 2004, our stockholders approved our Second Amended and Restated Cabot Microelectronics Corpo- ration 2000 Equity Incentive Plan (the “EIP”), as amended and restated September 23, 2008. On March 6, 2012, our stockholders approved our new 2012 Omnibus Incentive Plan (the “OIP”). As of this time, all share- based awards are now being made from the OIP, and the EIP is no longer available for any awards. The OIP is administered by the Compensation Committee of the Board of Directors and is intended to provide manage- ment with the flexibility to attract, retain and reward our employees, directors, consultants and advisors. The OIP allows for the granting of six types of equity incentive awards: stock options, restricted stock, restricted stock units, stock appreciation rights (SARs), performance- based awards and substitute awards. The OIP also pro- vides for cash incentive awards to be made. Substitute awards under the OIP are those awards that, in connec- tion with an acquisition, may be granted to employees, directors, consultants or advisors of the acquired com- pany, in substitution for equity incentives held by them in the seller or the acquired company. No SARs, perfor- mance awards, or substitute awards have been granted to date under either plan. The OIP authorizes up to 4,934,444 shares of stock to be granted thereunder, including up to 2,030,952 shares of stock in the aggre- gate of awards other than options or SARs, and up to 2,538,690 incentive stock options. The 4,934,444 shares of stock represents 2,901,360 shares of newly authorized shares and 2,033,084 shares previously available under the EIP. In addition, shares that become available from awards under the EIP and the OIP because of events such as forfeitures, cancellations or expirations, or because shares subject to an award are withheld to sat- isfy tax withholding obligations, will also be available for issuance under the OIP. Shares issued under our share- based compensation plans are issued from new shares rather than from treasury shares. On March 2, 2012, we completed a leveraged recapital- ization pursuant to which we paid a special cash divi- dend of $15 per share to our stockholders. In conjunction with this recapitalization, the EIP and the OIP required us to proportionally adjust the shares available for issuance under them. The number of shares available under the plans was increased by multiplying the num- ber by a factor of 1.45068, representing the ratio of the official NASDAQ closing price of $51.92 per share on March 1, 2012, the dividend payment date, to the official NASDAQ opening price of $35.79 per share on March 2, 2012, the ex-dividend date. The number of authorized shares in the OIP noted above includes the effects of this recapitalization. Non-qualified stock options issued under the OIP, as they were under the EIP, are generally time-based and provide for a ten-year term, with options generally vest- ing equally over a four-year period, with first vesting on the first anniversary of the award date. Beginning in March 2011, non-qualified stock options granted to non- employee directors on an annual basis vest 100% on the first anniversary of the award date. Compensation expense related to our stock option awards was $6,802, $6,871 and $7,081 in fiscal 2012, 2011 and 2010, respec- tively. For additional information on our accounting for share-based compensation, see Note 2 to the consoli- dated financial statements. Under the OIP, as under the EIP, employees may also be granted ISOs to purchase common stock at not less than the fair value on the date of the grant. No ISOs have been granted to date under either plan. Under the OIP, as under the EIP, employees and non- employees may be awarded shares of restricted stock or restricted stock units, which generally vest over a four-year period, with first vesting on the anniversary of the grant date. Beginning in March 2011, restricted stock units granted to non-employee directors on an annual basis vest 100% on the first anniversary of the award date. In general, shares of restricted stock and restricted stock units may not be sold, assigned, transferred, pledged, disposed of or otherwise encumbered. Hold- ers of restricted stock, and restricted stock units, if specified in the award agreements, have all the rights of stockholders, including voting and dividend rights, subject to the above restrictions, although the current holders of restricted stock units do not have such rights. Restricted shares under the OIP, as under the EIP, also may be purchased and placed “on deposit” by executive officers pursuant to the 2001 Deposit Share Program. Shares purchased under this Deposit Share Program receive a 50% match in restricted shares (“Award Shares”). These Award Shares vest at the end of a three-year period, and are subject to forfeiture upon early withdrawal of the deposit shares. Compen- sation expense related to our restricted stock and restricted stock unit awards and restricted shares matched at 50% pursuant to the Deposit Share Program was $5,674, $5,184 and $4,134 for fiscal 2012, 2011 and 2010, respectively. Employee Stock Purchase Plan In March 2008, our stockholders approved our 2007 Cabot Microelectronics Employee Stock Purchase Plan (the “ESPP”), which amended the ESPP for the primary purpose of increasing the authorized shares of common stock to be purchased under the ESPP from 475,000 designated shares to 975,000 shares. The ESPP required us to proportionally adjust the cumulative number of shares designated under the plan to reflect the effect of the leveraged recapitalization with a special cash 50 dividend. The cumulative number of shares designated under the ESPP was increased by a factor of 1.45068 representing the ratio of the official NASDAQ closing price of $51.92 per share on the dividend payment date, to the official NASDAQ opening price of $35.79 per share on the ex-dividend date. As of September 30, 2012, a total of 814,625 shares are available for purchase under the ESPP. The ESPP allows all full-time, and certain part-time, employees of our Company and its subsidiaries to purchase shares of our common stock through payroll deductions. Employees can elect to have up to 10% of their annual earnings withheld to purchase our stock, subject to a maximum number of shares that a participant may purchase and a maximum dollar expenditure in any six-month offering period, and certain other criteria. The provisions of the ESPP allow shares to be purchased at a price no less than the lower of 85% of the closing price at the beginning or end of each semi-annual stock purchase period. A total of 70,645, 61,364, and 38,050 shares were issued under the ESPP during fiscal 2012, 2011 and 2010, respectively. Compensation expense related to the ESPP was $735, $508 and $360 in fiscal 2012, 2011 and 2010, respectively. Directors’ Deferred Compensation Plan The Directors’ Deferred Compensation Plan (DDCP), as amended and restated September 23, 2008, became effective in March 2001 and applies only to our non- employee directors. The cumulative number of shares deferred under the plan was 71,781 and 47,530 as of September 30, 2012 and 2011, respectively. The DDCP required us to proportionally adjust the cumulative number of shares deferred under the plan to reflect the effect of the leveraged recapitalization with a special cash dividend. The cumulative number of shares deferred under the DDCP was increased by a factor of 1.45068 representing the ratio of the official NASDAQ closing price of $51.92 per share on the dividend payment date, to the official NASDAQ opening price of $35.79 per share on the ex-dividend date. Compensation expense related to the DDCP was $95, $83 and $68 for fiscal 2012, 2011 and 2010, respectively. Accounting for Share-Based Compensation We record share-based compensation expense for all share-based awards, including stock option grants, restricted stock and restricted stock unit awards and employee stock purchases. We calculate share-based compensation expense using the straight-line approach based on awards ultimately expected to vest, which requires the use of an estimated forfeiture rate. Our estimated forfeiture rate is primarily based on historical experience, but may be revised in future periods if actual forfeitures differ from the estimate. We use the Black-Scholes option-pricing model to estimate the grant date fair value of our stock options and employee stock purchase plan purchases. This model requires the input of highly subjective assumptions, including the price volatility of the underlying stock, the expected term of our stock options and the risk-free interest rate. We estimate the expected volatility of our stock options based on a combination of our stock’s historical volatil- ity and the implied volatilities from actively-traded options on our stock. Prior to fiscal 2012, we calculated the expected term of our stock options using the simpli- fied method, due to our limited amount of historical option exercise data, and we added a slight premium to this expected term for employees who meet the defi- nition of retirement eligible pursuant to their grants during the contractual term of the grant. The simplified method uses an average of the vesting term and the contractual term of the option to calculate the expected term. We experienced a significant increase in the vol- ume of stock option exercises in fiscal years 2011 and 2012. Consequently, we used this exercise data, as well as historical exercise data, to calculate the expected term of our stock options granted in fiscal 2012, rather than using the simplified method, and we continued to add a slight premium for employees who meet the definition of retirement eligible under their grant terms. The expected term we calculated using option exercise history was within 1% of the expected term calculated under the simplified method. The risk-free rate is derived from the U.S. Treasury yield curve in effect at the time of grant. The fair value of our share-based awards, as shown below, was estimated using the Black-Scholes model with the following weighted-average assumptions, excluding the effect of our leveraged recapitalization: Stock Options Weighted-average grant date fair value Expected term (in years) Expected volatility Risk-free rate of return Dividend yield ESPP Weighted-average grant date fair value Expected term (in years) Expected volatility Risk-free rate of return Dividend yield Year Ended September 30, 2012 2011 2010 $ 15.66 6.38 $ 16.49 6.28 $ 13.42 6.35 38% 1.3% — 36% 2.1% — 39% 2.6% — $ 8.78 0.50 $ 9.05 0.50 $ 7.45 0.50 36% 0.1% — 28% 0.2% — 33% 0.3% — 51 The Black-Scholes model is primarily used in estimating the fair value of short-lived exchange traded options that have no vesting restrictions and are fully transfer- able. Because employee stock options and employee stock purchases have certain characteristics that are significantly different from traded options, and because changes in the subjective assumptions can materially affect the estimated value, our use of the Black-Scholes model for estimating the fair value of stock options and employee stock purchases may not provide an accurate measure. Although the value of our stock options and employee stock purchases are determined in accor- dance with applicable accounting standards using an option-pricing model, those values may not be indica- tive of the fair values observed in a willing buyer/willing seller market transaction. The fair value of our restricted stock and restricted stock unit awards represents the closing price of our common stock on the date of award. Share-based compensation expense related to restricted stock and restricted stock unit awards is recorded net of expected forfeitures. Share-Based Compensation Expense Total share-based compensation expense for the years ended September 30, 2012, 2011 and 2010, is as follows: Income statement classifications: Cost of goods sold Research, development and technical Selling and marketing General and administrative Tax benefit Total share-based com- pensation expense, net of tax Year Ended September 30, 2012 2011 2010 $ 1,541 $ 1,221 $ 986 1,105 1,392 9,268 (4,118) 1,060 1,124 9,241 (4,060) 908 1,025 8,724 (4,145) $ 9,188 $ 8,586 $ 7,498 The costs presented in the preceding table for share- based compensation expense may not be representa- tive of the total effects on reported income for future years. Factors that may impact future years include, but are not limited to, changes to our historical approaches to long-term incentives such as described above, the timing and number of future grants of share-based awards, the vesting period and contractual term of share-based awards and types of equity awards granted. Further, share-based compensation may be impacted by changes in the fair value of future awards through variables such as fluctuations in and volatility of our stock price, as well as changes in employee exercise behavior and forfeiture rates. Our non-employee directors received annual equity awards in March 2012 at the time of our Annual Meeting of Stockholders, and a new non-employee director received an initial and annual equity award in June 2012, pursuant to the OIP. The award agreements for non- employee directors provide for immediate vesting of the award at the time of termination of service for any reason other than by reason of Cause, Death, Disability or a Change in Control, as defined in the OIP, if at such time the non-employee director has completed an equivalent of at least two full terms as a director of the Company, as defined in the Company’s bylaws. Five of the Company’s non-employee directors had completed at least two full terms of service as of the date of the March 2012 award. Consequently, the requisite service period for the award has already been satisfied and we recorded the fair value of $749 of the awards to these five directors to share-based compensation expense in the fiscal quarter ended March 31, 2012 rather than recording that expense over the one-year vesting period stated in the award agreement, as is done for the other three non-employee directors. Stock Option Activity As required by the EIP, the exercise prices and the num- ber of outstanding non-qualified stock options (NQSOs) were adjusted to reflect the leveraged recapitalization with a special cash dividend. The exercise prices of out- standing NQSOs were reduced by multiplying them by a factor of 0.68933, representing the ratio of the official opening price of our common stock on the NASDAQ stock market of $35.79 per share on the ex-dividend date, to the official closing price of our common stock on the NASDAQ stock market of $51.92 per share on the last trading day immediately prior to the ex-dividend date. The number of outstanding NQSOs was increased by multiplying the number by a factor of 1.45068, repre- senting the ratio of the official NASDAQ closing price of $51.92 per share on the dividend payment date to the official NASDAQ opening price of $35.79 per share on the ex-dividend date. This adjustment did not result in additional share-based compensation expense in the period as the fair value of the outstanding NQSOs immediately following the payment of the special cash dividend was equal to the fair value immediately prior to such distribution. 52 A summary of stock option activity under the EIP and OIP as of September 30, 2012, and changes during the fiscal 2012 are presented below: Stock Options Weighted-Average Exercise Price Weighted-Average Remaining Contractual Term (in years) Aggregate Intrinsic Value (in thousands) Outstanding at September 30, 2011 Granted Exercised Forfeited or canceled Mandatory proportional adjustment due to recapitalization Outstanding at September 30, 2012 Exercisable at September 30, 2012 Expected to vest at September 30, 2012 3,950,537 477,444 (976,645) (98,104) 1,780,394 5,133,626 3,585,204 1,388,924 $ 39.52 39.57 34.92 36.76 — $26.75 $27.18 $26.21 4.9 3.4 8.3 $44,262 $29,725 $12,399 The aggregate intrinsic value in the table above repre- sents the total pretax intrinsic value (i.e., for all in-the- money stock options, the difference between our closing stock price of $35.14 per share on the last trading day of fiscal 2012 and the exercise price, multiplied by the number of shares) that would have been received by the option holders had all option holders exercised their options on the last trading day of fiscal 2012. The total intrinsic value of options exercised was $6,879, $13,135 and $492 for fiscal 2012, 2011 and 2010, respectively. The total cash received from options exercised was $34,107, $35,955 and $2,283 for fiscal 2012, 2011 and 2010, respectively. The actual tax benefit realized for the tax deductions from options exercised was $2,239, $4,401 and $175 for fiscal 2012, 2011 and 2010, respec- tively. The total fair value of stock options vested during fiscal years 2012, 2011 and 2010 was $6,796, $6,321 and $8,494, respectively. As of September 30, 2012, there was $9,623 of total unrecognized share-based com- pensation expense related to unvested stock options granted under the EIP and OIP. That cost is expected to be recognized over a weighted-average period of 2.5 years. the ex-dividend date. This adjustment did not result in additional share-based compensation expense in the period as the fair value of the outstanding RSUs imme- diately following the payment of the special cash divi- dend was equal to the fair value immediately prior to such distribution. A summary of the status of the restricted stock awards and restricted stock unit awards outstanding that were granted under the EIP and OIP as of September 30, 2012, and changes during fiscal 2012, are presented below: Restricted Stock Awards and Units Weighted- Average Grant Date Fair Value Nonvested at September 30, 2011 Granted Vested Forfeited Mandatory proportional adjustment due to recapitalization Nonvested at September 30, 2012 369,681 164,170 (167,159) (10,242) $ 34.29 39.77 34.60 31.55 37,674 — 394,124 $34.15 Restricted Stock Similarly, the EIP required that we adjust the number of outstanding restricted stock units (RSUs) as a result of the leveraged recapitalization with a special cash divi- dend. The number of outstanding RSUs was increased by multiplying the number by a factor of 1.45068, repre- senting the ratio of the official NASDAQ closing price of $51.92 per share on the dividend payment date to the official NASDAQ opening price of $35.79 per share on As of September 30, 2012, there was $8,084 of total unrecognized share-based compensation expense related to nonvested restricted stock awards and restricted stock units under the EIP and OIP. That cost is expected to be recognized over a weighted-average period of 2.5 years. The total fair values of restricted stock awards and restricted stock units vested during fiscal years 2012, 2011 and 2010 were $5,784, $4,452 and $3,209, respectively. 53 13. Other Income (Expense), Net Other income (expense), net, consisted of the following: stock—other September 30, 2011 12. Savings Plan Effective in May 2000, we adopted the Cabot Microelec- tronics Corporation 401(k) Plan (the “401(k) Plan”), which is a qualified defined contribution plan, covering all eli- gible U.S. employees meeting certain minimum age and eligibility requirements, as defined by the 401(k) Plan. Participants may make elective contributions of up to 60% of their eligible compensation. All amounts contrib- uted by participants and earnings on these contribu- tions are fully vested at all times. The 401(k) Plan provides for matching and fixed non-elective contributions by the Company. Under the 401(k) Plan, the Company will match 100% of the first four percent of the participant’s eligible compensation and 50% of the next two percent of the participant’s eligible compensation that is con- tributed, subject to limitations required by government regulations. Under the 401(k) Plan, all U.S. employees, even those who do not contribute to the 401(k) Plan, receive a contribution by the Company in an amount equal to four percent of eligible compensation, and thus are participants in the 401(k) Plan. Participants are 100% vested in all Company contributions at all times. The Company’s expense for the 401(k) Plan totaled $4,210, $4,201 and $2,981 for the fiscal years ended September 30, 2012, 2011 and 2010, respectively. Interest income Other expense Year Ended September 30, 2012 2011 2010 $ 146 (1,490) $ 238 (1,556) $ 228 (729) Total other income (expense), net $ (1,344) $ (1,318) $ (501) Other expense primarily represents the gains and losses recorded on transactions denominated in foreign cur- rencies. Other expense in fiscal 2012 was consistent with other expense recorded in fiscal 2011. The increase in other expense in fiscal 2011 from fiscal 2010 was primar- ily due to foreign exchange effects, primarily related to changes in the exchange rate of the Japanese yen and the New Taiwan dollar to the U.S. dollar, net of the gains and losses incurred on forward foreign exchange con- tracts discussed in Note 10 of this Form 10-K. As dis- closed in Note 1, prior period other income (expense) amounts have been adjusted to exclude interest expense to conform to the current year presentation. 14. Stockholders’ Equity The following is a summary of our capital stock activity over the past three years: Number of Shares September 30, 2009 Exercise of stock options Restricted stock under EIP, net of forfeitures Restricted stock under Deposit Share Plan Common stock under ESPP Repurchases of common stock under share repurchase plans Repurchases of common stock—other September 30, 2010 Exercise of stock options Restricted stock under EIP, net of forfeitures Restricted stock under Deposit Share Plan, net of forfeitures Common stock under ESPP Repurchases of common stock under share repurchase plans Repurchases of common Exercise of stock options Restricted stock under EIP and OIP, net of forfeitures Restricted stock under Deposit Share Plan, net of forfeitures Common stock under ESPP Repurchases of common stock under share repurchase plans Repurchases of common stock—other Common Stock 26,143,116 74,019 127,390 2,140 38,050 26,384,715 1,085,965 115,069 5,223 61,364 27,652,336 976,645 159,879 5,022 70,645 Treasury Stock 2,698,234 723,184 24,651 3,446,069 1,235,668 33,840 4,715,577 929,407 37,304 September 30, 2012 28,864,527 5,682,288 Common Stock Each share of common stock, including of restricted stock awards, but not restricted stock units, entitles the holder to one vote on all matters submitted to a vote of Cabot Microelectronics’ stockholders. Common stockholders are entitled to receive ratably the divi- dends, if any, as may be declared by the Board of Directors. The number of authorized shares of common stock is 200,000,000 shares. Share Repurchases In November 2010, our Board of Directors authorized a share repurchase program for up to $125,000 of our outstanding common stock, which became effective on the authorization date. We repurchased 671,100 shares for $29,105 during fiscal 2011 and we repurchased 929,407 shares for $33,026 during fiscal 2012 under this 54 The provision for income taxes at our effective tax rate differed from the statutory rate as follows: Federal statutory rate U.S. benefits from research and experimentation activities State taxes, net of federal effect Foreign income at other than U.S. rates Executive compensation Share-based compensation Adjustment of prior amounts, net of valuation allowance Domestic production deduction Tax-exempt interest income Other, net Year Ended September 30, 2012 2011 2010 35.0% 35.0% 35.0% (0.5) 0.2 (1.9) 0.8 0.7 0.9 (0.5) (0.0) 0.4 (2.0) 0.6 (2.8) 1.4 3.3 — (0.8) (0.1) (0.1) (0.6) 0.5 (2.7) — 0.3 — (0.1) (0.1) 0.2 Provision for income taxes 35.1% 34.5% 32.5% In fiscal 2012, 2011 and 2010, we elected to permanently reinvest the earnings of certain of our foreign subsidiar- ies outside the U.S. rather than repatriating the earnings to the U.S. We have not provided deferred taxes on approximately $31.1 million of undistributed earnings of such subsidiaries. These earnings could become subject to additional income tax if they are remitted as divi- dends to the U.S. parent company, loaned to the U.S. parent company, or upon sale of subsidiary stock. Determination of the amount of unrecognized deferred tax liability related to these earnings is not practicable. The increase in our effective tax rate in fiscal 2012 was primarily due to the expiration of the research and experimentation tax credit effective December 31, 2011, decreased income in the foreign subsidiaries where we have elected to permanently reinvest earnings, and cer- tain adjustments made to prior year tax estimates. These increases were partially offset by decreased tax effects on share-based compensation and decreased taxable executive compensation in excess of limits defined in section 162(m) of the Internal Revenue Code. As discussed in footnote 1 of this 10-K under the head- ing “Results of Operations”, income tax expense in fis- cal 2012 included $973 of non-material adjustments to correct various prior period amounts and income tax expense in fiscal 2011 included $671 of adjustments to executive compensation in fiscal 2008 through 2010 and a $497 reversal of a deferred tax asset for certain share- based compensation expense. program. As of December 13, 2011, we had $82,869 remaining under this share repurchase program. In conjunction with a new capital management initiative, on December 13, 2011, our Board of Directors autho- rized an increase in the amount available under our share repurchase program to $150,000. With this increased authorization, as of September 30, 2012, $130,000 remains outstanding under our share repur- chase program. Shares are repurchased from time to time, depending on market conditions, in open market transactions, at management’s discretion. We repur- chased 564,568 shares for $25,000 in fiscal 2011 under a prior share repurchase program, which was completed during the fiscal quarter ended March 31, 2011. During fiscal 2010, we repurchased 723,184 shares of common stock under this prior program at a cost of $24,998. To date, we have funded share repurchases under our share repurchase program from our existing cash balance, and anticipate we will continue to do so. The program, which became effective on the authorization date, may be suspended or terminated at any time, at the Company’s discretion. For additional information on share repurchases, see Part II, Item 5. “Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities”. Separate from this share repurchase program, a total of 37,304, 33,840 and 24,651 shares were purchased during fiscal 2012, 2011 and 2010, respectively, pursuant to the terms of our EIP and OIP as shares withheld from award recipients to cover payroll taxes on the vesting of shares of restricted stock granted under the EIP and OIP. 15. Income Taxes Income before income taxes was as follows: Domestic Foreign Total Year Ended September 30, 2012 2011 2010 $ 55,555 7,316 $ 54,886 24,026 $ 39,835 33,442 $ 62,871 $ 78,912 $ 73,277 Taxes on income consisted of the following: U.S. federal and state: Current Deferred Total Foreign: Current Deferred Total Year Ended September 30, 2012 2011 2010 $ 19,975 (308) $ 15,700 6,194 $ 15,372 (2,643) $ 19,667 $ 21,894 $ 12,729 $ 5,593 (3,215) $ 6,616 (1,260) $ 10,597 493 2,378 5,356 11,090 Total U.S. and foreign $ 22,045 $ 27,250 $ 23,819 55 The accounting guidance regarding uncertainty in income taxes prescribes a threshold for the financial statement recognition and measurement of tax positions taken or expected to be taken on a tax return. Under these stan- dards, we may recognize the tax benefit of an uncertain tax position only if it is more likely than not that the tax position will be sustained by the taxing authorities, based on the technical merits of the position. The following table presents the changes in the balance of gross unrecognized tax benefits during the last three fiscal years: Balance September 30, 2009 Additions for tax positions relating to the current fiscal year Additions for tax positions relating to prior fiscal years Settlements with taxing authorities Lapse of statute of limitations Balance September 30, 2010 Additions for tax positions relating to the current fiscal year Additions for tax positions relating to prior fiscal years Settlements with taxing authorities Lapse of statute of limitations Balance September 30, 2011 Additions for tax positions relating to the current fiscal year Additions for tax positions relating to prior fiscal years Settlements with taxing authorities Lapse of statute of limitations Balance September 30, 2012 $ 249 — 153 (28) (201) 173 123 307 — — 603 51 114 (353) (132) $ 283 We recognize interest and penalties related to uncertain tax positions as income tax expense in our financial statements. Interest and penalties accrued on our Consolidated Balance Sheet were $4 and $19 at September 30, 2012 and 2011, respectively, and interest and penalties charged to expense were not material. We believe the tax periods open to examination by the U.S. federal government include fiscal years 2009 through 2011. We believe the tax periods open to exam- ination by U.S. state and local governments include fis- cal years 2008 through 2011 and the tax periods open to examination by foreign jurisdictions include fiscal years 2008 through 2011. We do not anticipate a significant change to the total amount of unrecognized tax bene- fits within the next 12 months. Significant components of deferred income taxes were as follows: Deferred tax assets: Employee benefits Inventory Bad debt reserve Share-based compensation expense Net operating losses Other Valuation allowance September 30, 2012 2011 $ 4,035 2,930 1,708 12,659 2,292 2,656 (1,378) $ 3,246 2,886 387 12,184 768 1,558 — Total deferred tax assets $ 24,902 $ 21,029 Deferred tax liabilities: Translation adjustment Depreciation and amortization Unremitted foreign earnings Other $ 7,966 3,776 1,810 645 $ 10,576 1,568 3,647 127 Total deferred tax liabilities $ 14,197 $ 15,918 As of September 30, 2012, the Company had foreign and state net operating loss carryforwards (NOLs) of $7,772 and $1,528, respectively, which will expire begin- ning in fiscal year 2017 through fiscal year 2030. We pro- vided a gross valuation allowance of $1,699 on these NOLs during fiscal 2012. As of September 30, 2012, the Company also had $1,818 in state tax credit carry- forwards, for which we have recorded a $1,047 gross valuation allowance in fiscal 2012. 16. Commitments and Contingencies Legal Proceedings While we are not involved in any legal proceedings that we believe will have a material impact on our consoli- dated financial position, results of operations or cash flows, we periodically become a party to legal proceed- ings in the ordinary course of business. For example, in 2011, we concluded litigation in the United States against a competitor in which the validity of certain of our CMP slurry patents for tungsten CMP was upheld, although the specific competitive products at issue were found to not infringe the claims at issue. Product Warranties We maintain a warranty reserve that reflects manage- ment’s best estimate of the cost to replace product that does not meet customers’ specifications and perfor- mance requirements, and costs related to such replace- ment. The warranty reserve is based upon a historical product replacement rate, adjusted for any specific known conditions or circumstances. Additions and deductions to the warranty reserve are recorded in 56 cost of goods sold. Our warranty reserve requirements changed during fiscal 2012 as follows: Balance as of September 30, 2011 Reserve for product warranty during the reporting period Settlement of warranty Balance as of September 30, 2012 $ 384 867 (892) $ 359 Indemnification In the normal course of business, we are a party to a variety of agreements pursuant to which we may be obligated to indemnify the other party with respect to certain matters. Generally, these obligations arise in the context of agreements entered into by us, under which we customarily agree to hold the other party harmless against losses arising from items such as a breach of certain representations and covenants including title to assets sold, certain intellectual property rights and cer- tain environmental matters. These terms are common in the industries in which we conduct business. In each of these circumstances, payment by us is subject to certain monetary and other limitations and is conditioned on the other party making an adverse claim pursuant to the procedures specified in the particular agreement, which typically allow us to challenge the other party’s claims. We evaluate estimated losses for such indemnifications under the accounting standards related to contingen- cies and guarantees. We consider such factors as the degree of probability of an unfavorable outcome and the ability to make a reasonable estimate of the amount of loss. To date, we have not experienced material costs as a result of such obligations and, as of September 30, 2012, have not recorded any liabilities related to such indemnifications in our financial statements as we do not believe the likelihood of such obligations is probable. Lease Commitments We lease certain vehicles, warehouse facilities, office space, machinery and equipment under cancelable and noncancelable leases, all of which expire within six years from now and may be renewed by us. Lease commit- ments also include certain costs associated with our pad finishing operation located at Taiwan Semiconductor Manufacturing Company, which are accounted for as an operating lease. Rent expense under such arrange- ments during fiscal 2012, 2011 and 2010 totaled $3,199, $2,934 and $2,480, respectively. In December 2001 we entered into a fumed alumina supply agreement with Cabot Corporation under which we agreed to pay Cabot Corporation for the expansion of a fumed alumina manufacturing facility in Tuscola, Illinois. The arrangement for the facility has been treated as a capital lease for accounting purposes and the pres- ent value of the minimum quarterly payments resulted in an initial $9,776 lease obligation and related leased asset. The agreement expired in December 2011. Future minimum rental commitments under noncancel- able leases as of September 30, 2012 are as follows: Fiscal Year 2013 2014 2015 2016 2017 Thereafter Amount related to interest Capital lease obligation Operating Capital $2,830 2,179 1,116 1,013 785 520 $8,443 $ 2 5 5 5 4 — 21 — $21 Purchase Obligations Purchase obligations include our take-or-pay arrange- ments with suppliers, and purchase orders and other obligations entered into in the normal course of busi- ness regarding the purchase of goods and services. We purchase fumed silica primarily under a fumed silica supply agreement with Cabot Corporation, our former parent company that is not a related party, that became effective in January 2004, and was amended in September 2006 and in April 2008, the latter of which extended the termination date of the agreement from December 2009 to December 2012 and also changed the pricing and some other non-material terms of the agreement to the benefit of both parties. We are gener- ally obligated to purchase fumed silica for at least 90% of our six-month volume forecast for certain of our slurry products, to purchase certain minimum quantities every six months, and to pay for the shortfall if we purchase less than these amounts. We are currently working with Cabot Corporation to negotiate the terms of a new fumed silica supply agreement that we anticipate would take effect following the expiration of the current agree- ment. Since December 2001, we have purchased fumed alumina primarily under a fumed alumina supply agree- ment with Cabot Corporation that expired in December 2011. We are now operating under a renewed fumed alumina supply agreement with Cabot Corporation, which expires in April 2013, under which we are obli- gated to pay certain fixed, capital and variable costs, and have certain take-or-pay obligations, We currently anticipate we will not have to pay any shortfall under these agreements.

Earnings Per Share The standards of accounting for earnings per share require companies to provide a reconciliation of the numerator and denominator of the basic and diluted earnings per share computations. Basic and diluted earnings per share were calculated as follows: Numerator: Net income Denominator: Weighted-average common shares (Denominator for basic calculation) Weighted-average effect of dilutive securities: Share-based compensation Diluted weighted-average common shares (Denominator for diluted calculation) Earnings per share: Basic Diluted Year Ended September 30, 2012 2011 2010 $40,826 $51,662 $49,458 22,506,408 22,895,568 23,083,807 773,890 539,036 188,772 23,280,298 23,434,604 23,272,579 $ 1.81 $ 1.75 $ 2.26 $ 2.20 $ 2.14 $ 2.13 For the twelve months ended September 30, 2012, 2011, and 2010, approximately 1.3 million, 1.3 million and 2.6 million shares, respectively, attributable to outstanding stock options were excluded from the calculation of diluted earnings per share because the exercise price of the options was greater than the average market price of our common stock and, therefore, their inclusion would have been anti-dilutive. than ten percent of our total revenue in fiscal 2012, 2011 and 2010: Revenue: Taiwan South Korea Japan Singapore Year Ended September 30, 2012 2011 2010 $124,732 68,573 56,488 * $132,089 56,321 57,889 47,441 $129,533 42,669 60,207 44,316 18.

The Company’s management is responsible for the integrity of these statements and of the underlying data, estimates and judgments. The Company’s management establishes and maintains a system of internal accounting controls designed to provide reasonable assurance that its assets are safe- guarded from loss or unauthorized use, transactions are properly authorized and recorded, and that financial records can be relied upon for the preparation of the consolidated financial statements. This system includes written policies and procedures, a code of business con- duct and an organizational structure that provides for appropriate division of responsibility and the training of personnel. This system is monitored and evaluated on an ongoing basis by management in conjunction with its internal audit function. The Company’s management assesses the effectiveness of its internal control over financial reporting on an annual basis. In making this assessment, management uses the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control—Integrated Framework. Management acknowl- edges, however, that all internal control systems, no matter how well designed, have inherent limitations and can provide only reasonable assurance with respect to financial statement preparation and presentation. In addition, the Company’s independent registered public accounting firm evaluates the Company’s internal control over financial reporting and performs such tests and other procedures as it deems necessary to reach and express an opinion on the fairness of the financial statements. In addition, the Audit Committee of the Board of Directors provides general oversight responsibility for the financial statements. Composed entirely of Directors who are independent and not employees of the Company, the Committee meets periodically with the Company’s management, internal auditors and the independent registered public accounting firm to review the quality of financial reporting and internal controls, as well as results of auditing efforts. The internal auditors and independent registered public accounting firm have full and direct access to the Audit Committee, with and without management present. /s/ William P. Noglows William P.

Changes in and Disagreements with Accountants on Accounting and Financial Disclosure None. Item 9A. Controls and Procedures Evaluation of Disclosure Controls and Procedures Our management, with the participation of our Chief Executive Officer (CEO) and Chief Financial Officer (CFO), has evaluated the effectiveness of the design and operation of our disclosure controls and proce- dures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended (“the Exchange Act”)), as of September 30, 2012. Based on that eval- uation, our CEO and CFO have concluded that our disclosure controls and procedures were effective to ensure that information required to be disclosed in our Exchange Act reports is recorded, processed, summa- rized and reported within the time periods specified in the SEC’s rules and forms, and to ensure that such infor- mation is accumulated and communicated to manage- ment, including the CEO and CFO, as appropriate to allow timely decisions regarding required disclosure. While we believe the present design of our disclosure controls and procedures is effective enough to make known to our senior management in a timely fashion all material information concerning our business, we intend to continue to improve the design and effectiveness of our disclosure controls and procedures to the extent necessary in the future to provide our senior manage- ment with timely access to such material information, and to correct any deficiencies that we may discover in the future, as appropriate. Management’s Report on Internal Control Over Financial Reporting Our management is responsible for establishing and maintaining adequate internal control over financial reporting for the Company. Internal control over finan- cial reporting is defined in Rule 13a-15(f) or Rule 15d-15(f) promulgated under the Securities Exchange Act of 1934 as a process designed by, or under the supervision of, the Company’s CEO and CFO to provide reasonable assurance regarding the reliability of our financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles in the United States of America. Internal control over financial reporting includes policies and procedures that: pertain to the mainte- nance of records that in reasonable detail accurately and fairly reflect our transactions and dispositions of the Company’s assets; provide reasonable assurance that transactions are recorded as necessary for preparation of our financial statements in accordance with generally accepted accounting principles; provide reasonable assurance that receipts and expenditures of Company assets are made in accordance with management autho- rization; and provide reasonable assurance that unauthor- ized acquisition, use or disposition of Company assets that could have a material effect on our financial state- ments would be prevented or detected on a timely basis. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstate- ments. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. Our management evaluated the effectiveness of our internal control over financial reporting based on the framework in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on this evaluation, our management concluded that the Com- pany’s internal control over financial reporting was effective as of September 30, 2012. The effectiveness of the Company’s internal control over financial report- ing as of September 30, 2012 has been audited by PricewaterhouseCoopers LLP, an independent regis- tered public accounting firm, as stated in their attesta- tion report which appears under Item 8 of this Annual Report on Form 10-K. Changes in Internal Control Over Financial Reporting There were no changes in our internal control over finan- cial reporting that occurred during our most recent fiscal quarter that have materially affected, or are rea- sonably likely to materially affect, our internal control over financial reporting. 62 Inherent Limitations on Effectiveness of Controls Because of inherent limitations, our disclosure controls or our internal control over financial reporting may not prevent all errors and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objec- tives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all con- trol issues and instances of fraud, if any, within the Company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of a simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people or by management override of the controls. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions; over time, controls may become inadequate because of changes in conditions, or the degree of compliance with policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected. Item 9B. Other Information None. PART III Item 10.
