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 customers 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 foreign 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 important in our industry because we develop complex technical 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 combination of patent, trademark, copyright and trade secret laws, as well as employee and third-party nondisclosure and assignment agreements. Due to our international operations, we pursue protection in different jurisdictions, which may provide varying degrees of protection, 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. our internal growth and development efforts. Acquisitions and investments involve numerous risks, including the following: difficulties and risks in integrating the operations, technologies, products and personnel of acquired companies; diversion of management’s attention from normal daily operations of the business; increased risk associated with foreign operations; potential 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 positions; 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 unfamiliar supply chains or relatively small supply partners; insufficient revenues to offset increased expenses associated 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 anticipated benefits of a business combination, asset acquisition 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 margins, 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 inherently 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 expertise 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 pursuing other surface modification applications. Expanding our business into new product areas could involve technologies, production processes and business models in which we have limited experience, and we may not be able to develop and produce products or provide services 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. 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 technologies, assets and companies, either through acquisitions, investments or alliances, in order to supplement 14
