customer orders makes it difficult for us to predict industry trends. If the global economy experiences further weakness and/or the semiconductor industry weakens, whether in general or as a result of specific factors, such as current macroeconomic factors, or unpredictable 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 material 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 quarter 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 customers may produce, such as logic devices versus memory 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-toquarter changes in customer order patterns; market share gains and losses; and pricing changes by us and our competitors. 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 manufacturing 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 semiconductor 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 consumables 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 seriously 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 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 ability 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 semiconductor 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 12 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
