FINANCIAL INFORMATION, SEGMENT REPORTING AND GEOGRAPHIC AREAS

          For financial reporting purposes, we operate in a single segment, standard semiconductor products, through our various design, manufacturing and distribution facilities. We sell product primarily through our operations in North America, Asia and Europe. We aggregated our products because the products are similar and have similar economic characteristics, and the products are similar in production process and share the same customer type. See Note 20 of “Notes to Consolidated Financial Statements” of this Annual Report for addition information about geographic areas and segment reporting including our net sales, net income and total assets.

OUR INDUSTRY

          Semiconductors are critical components used in the manufacture of an increasing variety of electronic products and systems. Since the invention of the transistor in 1948, continuous improvements in semiconductor processes and design technologies have led to smaller, more complex and more reliable devices at a lower cost per function. The availability of low-cost semiconductors, together with increased customer demand for sophisticated electronic systems, has led to the proliferation of semiconductors in diverse end-use applications in the consumer electronics, computing, industrial, communications and automotive sectors. These factors have also led to an increase in the total number of semiconductor components in individual electronic systems and an increase in value of these components as a percentage of the total cost of the electronic systems in which they are incorporated.

OUR COMPETITIVE STRENGTHS

          We believe our competitive strengths include the following:

          Flexible, scalable and cost-effective manufacturing — Our manufacturing operations are a core element of our success, and we have designed our manufacturing base to allow us to respond quickly to changes in demand trends in the end-markets we serve. For example, we have structured our Shanghai assembly, test and packaging facilities to enable us to rapidly and efficiently add capacity and adjust product mix to meet shifts in customer demand and overall market trends. As a result, for the past several years we have operated our Shanghai facilities at near full capacity, while at the same time significantly expanding that capacity. Additionally, the Shanghai location of our manufacturing operations provides us with access to a highly-skilled workforce at a low overall cost base while enabling us to better serve our leading customers, many of which are located in Asia. Currently, due to the decrease in global demand for our products, our Shanghai facilities are under-loaded. For at least the beginning of 2009, we do not expect to operate our Shanghai facilities near full capacity. Therefore we are taking the opportunity to transfer the production of products acquired in our purchase of Zetex sooner than originally planned thereby reducing our dependence on subcontractor OEMs and maximizing the utilization of our internal capacity.

           Integrated packaging expertise — We believe that we have particular expertise in designing and manufacturing innovative and proprietary packaging solutions that integrate multiple separate discrete elements into a single semiconductor product called an array. Our ability to design and manufacture highly integrated semiconductor solutions provides our customers with products of equivalent functionality with fewer individual parts, and at lower overall cost, than alternative products. This combination of integration, functionality and miniaturization makes our products well suited for high-volume consumer devices such as digital audio players, notebook computers, flat-panel displays, mobile handsets, digital cameras and set-top boxes.

          Broad customer base and diverse end-markets — Our customers are comprised of leading OEMs as well as leading EMS providers. Overall, we serve over 230 direct customers worldwide and over 10,000 additional customers through our distributors. Our products are ultimately used in end-products in a number of markets served by our broad customer base, which we believe makes us less dependent on either specific customers or specific end-user applications.

          Customer focused product development — Effective collaboration with our customers and a high degree of customer service are essential elements of our business. We believe focusing on dependable delivery of semiconductor solutions tailored to specific end-user applications, has fostered deep customer relationships and created a key competitive advantage for us in the highly fragmented discrete and analog semiconductor marketplace. We believe our close relationships with our OEM and EMS customers have provided us with deeper insight into our customers’ product needs. This results in differentiation in our product designs and often provides us with insight into additional opportunities for new design wins in our customers’ products. See “Risk Factors — We are and will continue to be under continuous pressure from our customers and competitors to reduce the price of our products, which could adversely affect our growth and profit margins” in Part I, Item 1A of this Annual Report for additional information.

          Management continuity and experience — We believe that the continuity of our management team is a critical competitive strength. Three members of our executive team average over 15 years of service at the Company and the length of their service with us has created significant institutional insight into our markets, our customers and our operations. Additionally, the other eight executive officers have an average of over 25 years experience in the semiconductor industry.

          In June 2005, we appointed Dr. Keh-Shew Lu as President and Chief Executive Officer. Dr. Lu has served as a director of Diodes since 2001 and has over 30 years of relevant industry experience. Dr. Lu began his career at Texas Instruments, Inc. (“TI”) in 1974 and retired in 2001 as Senior Vice President and General Manager of Worldwide Analog, Mixed-Signal and Logic Products. Our Chief Financial Officer, Secretary and Treasurer, Carl Wertz, has been employed by us since 1993 and has over 20 years of financial experience in manufacturing and distribution industries. Joseph Liu, Senior Vice President of Operations, joined us in 1990 and has over 30 years of relevant industry experience, having started his career in 1971 at TI. Similarly, Mark King, Senior Vice President of Sales and Marketing, has been employed by us since 1991.

          Management expansion — In 2006, we hired Richard White, Senior Vice President of Finance, who brought with him over 30 years of senior level finance experience, including 25 years at TI; and Edmund Tang, Vice President of Corporate Administration, with over 30 years of managerial and engineering experience. Also in 2006, Francis Tang, Vice President of Discrete Product Development, was promoted from Global Product Manager.

          In 2008, we strengthened our executive management team with the addition of the following management team members: Hans Rohrer, Senior Vice President of Business Development, who brought 30 years of relevant industry experience and joined us as a result of the acquisition of Zetex, at which he was CEO; Colin Greene, Europe President and Vice President of Europe Sales and Marketing, who brought with him over 20 years of relevant industry experience and joined us as a result of the acquisition of Zetex, at which he was COO; and Julie Holland, Vice President of Worldwide Analog Products, who came to us from TI and

brought with her over 23 years of relevant industry experience. Also in 2008, we promoted Tung Cheo (“T.J.”) Lee to Vice President of Packaging Operations and General Manager of China Operations.

OUR STRATEGY

          As discussed in detail in Part II, Item 7 of this Annual Report, the global economic downturn has resulted in a decrease in demand for our products, and we expect the decrease in demand to continue until economic conditions improve. Even as we are experiencing a decrease in product demand, our strategy is to continue to enhance our position as a leading global manufacturer and supplier of high-quality semiconductor products by transferring the production of products acquired in our purchase of Zetex to maximize internal capacity, applying our packaging expertise to the Zetex products and adding other product lines, such as power management products.

          The principal elements of our strategy include the following:

          Continue to rapidly introduce innovative discrete and analog semiconductor products — We intend to maintain our rapid pace of new product introductions, especially for high-volume, growth applications with short design cycles, such as digital audio players, notebook computers, flat-panel displays, mobile handsets, digital cameras, set-top boxes and other consumer electronics and computing devices. During 2008, we introduced approximately 230 new devices and achieved new design wins at over 100 OEMs. Although a design win from a customer does not necessarily guarantee future sales to that customer, we believe that continued introduction of new and differentiated product solutions is critically important in maintaining and extending our market share in the highly competitive semiconductor marketplace.

          Sales of new products (products that have been sold for three years or less) for the years ended December 31, 2006, 2007 and 2008 amounted to 28.2%, 35.1% and 26.9% of total sales, respectively, including the contribution of recent acquisitions. New products generally have gross profit margins that are higher than the margins of our standard products, and we expect net sales derived from new products to increase in absolute terms. New product revenue in 2008 was driven by products in sub-miniature array, QFN, PowerDI^â323, PowerDI^â123, PowerDI^â5, SBR^â and Schottky platforms, in both the discrete and analog product lines. We feel the sales from new products is an important measure given the short life cycles of some of our products. See “Risk Factors — Our business may be adversely affected by obsolete inventories as a result of changes in demand for our products and change in life cycles of our products” in Part I, Item 1A of this Annual Report for additional information about product life cycles.

          Expand our available market opportunities — We intend to aggressively maximize our opportunities in the standard semiconductor market as well as in related markets where we can apply our semiconductor design and manufacturing expertise. A key element of this is leveraging our highly integrated packaging expertise through our Application Specific Multi-Chip Circuit (“ASMCC”) product platform, which consists of standard arrays, function specific arrays and end-equipment specific arrays. We intend to achieve this by:

	•		Continuing to focus on increasing packaging integration, particularly with our existing standard array and customer-specific array products, in order to achieve products with increased circuit density, reduced component count and lower overall product cost;
	•		Expanding existing products and developing new products in our function specific array lines, which combine multiple discrete semiconductor components to achieve specific common electronic device functionality at a low cost; and
	•		Developing new product lines, which we refer to as end-equipment specific arrays, which combine discrete components with logic and/or standard analog circuits to provide system-level solutions for high-volume, high-growth applications.

          Maintain intense customer focus — We intend to strengthen and deepen our customer relationships. We believe that continued focus on customer service is important, especially in the current economic environment, and will help to increase our net sales, operating performance and overall market share once economic conditions improve. To accomplish this, we intend to continue to closely collaborate with our customers to design products that meet their specific needs. A critical element of this strategy is to continue to further reduce our design cycle time in order to quickly provide our customers with innovative products. During 2008, we expanded our quality systems team to ensure we deliver high quality products. Additionally, to support our customer-focused strategy, we historically expanded our sales force and field application engineers, particularly in Asia and Europe, during periods of growth. Given the current economic conditions, we have deferred hiring additional employees since the fourth quarter of 2008, when we implemented a hiring freeze. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Cost Reduction Initiative” section of Part II, Item 7 of this Annual Report for additional information about the hiring freeze and other cost reduction initiatives.

          Enhance cost competitiveness — A key element of our success is our overall low-cost base. While we believe that our Shanghai manufacturing facilities are among the most efficient in the industry, we will continue to refine our proprietary manufacturing processes and technology to achieve additional cost efficiencies. Historically, we have operated our facilities at high utilization rates and increased product yields, in order to achieve meaningful economies of scale. Given the current economic conditions, our facilities are currently running at abnormally low levels and will remain at abnormally low levels until economic conditions improve.

          Pursue selective strategic acquisitions — As part of our strategy to expand our standard semiconductor product offerings and to maximize our market opportunities, we may acquire discrete, analog or mixed-signal technologies, product lines or companies in order to support our ASMCC product platform and enhance our standard and new product offerings.

          In November 2006, we purchased the net assets of APD Semiconductor, Inc., a privately held U.S.-based fabless semiconductor company, including its patented and trademarked SBR^® (super barrier rectifier) technology. SBR^® technology allows for increased power saving with better efficiency and reliability at higher operating temperatures. It will further strengthen our technology leadership in the discrete semiconductor market and expand our product capabilities across important segments of our end-markets.

          In June 2008, we completed the acquisition of Zetex, a publicly traded UK semiconductor company and a leading provider of discrete and high performance analog semiconductor products for signal processing and power management. Zetex designs and manufactures a broad range of standard and application focused linear integrated circuits and discrete semiconductor products using a wide variety of wafer processing technologies. Headquartered in Oldham England, Zetex has a wafer fabrication plant in the UK and carries out package development, assembly and test at its facilities in Germany and China and through subcontractors in Asia. Zetex operates sales offices in Munich, Hong Kong and New York and is supported by a global network of distributors and manufacturer’s representatives. See Note 2 of “Notes to Consolidated Financial Statements” and “Risk Factors — Part of our growth strategy involves identifying and acquiring companies with complementary product lines or customers. We may be unable to identify suitable acquisition candidates or consummate desired acquisitions and, if we do make any acquisitions, we may be unable to successfully integrate any acquired companies with our operations” in Part I, Item 1A of this Annual Report for additional information about our recent acquisitions.

CONVERTIBLE SENIOR NOTES

          On October 12, 2006, we issued and sold convertible senior notes with an aggregate principal amount of $230 million due 2026 (the “Notes”), which pay 2.25% interest per annum on the principal amount of the Notes, payable semi-annually in arrears on April 1 and October 1 of each year, beginning on April 1, 2007.

          The Notes will be convertible into cash or, at our option, cash and shares of our Common Stock based on an initial conversion rate, subject to adjustment, of 25.6419 shares (split adjusted) per $1,000 principal amount of Notes (which represents an initial conversion price of $39.00 per share (split adjusted), in certain circumstances. In addition, following a “make-whole fundamental change” that occurs prior to October 1, 2011, we will, at our option, increase the conversion rate for a holder who elects to convert its Notes in connection with such “make-whole fundamental change,” in certain circumstances.

          During the fourth quarter of 2008 and the first quarter of 2009, we repurchased $46.5 million and $9.6 million principal amount of the Notes for approximately $23.2 million and $6.6 million in cash, respectively. Beginning January 1, 2009, we will adopt Financial Accounting Standards Board (“FASB”) Staff Position (“FSP”) APB 14-1, Accounting for Convertible Debt Instruments That May Be Settled in Cash upon Conversion (Including Partial Cash Settlement), that will change how we account for our Notes and significantly increase our non-cash interest expense. See Notes 1 and 10 of “Notes to Consolidated Financial Statements” of this Annual Report for additional information about the Notes, the repurchase and FSP APB 14-1.

OUR PRODUCTS

          Our product portfolio includes over 4,000 products that are designed for use in high-volume consumer devices such as digital audio players, notebook computers, flat-panel displays, mobile handsets, digital cameras and set-top boxes. We target and serve end-equipment market segments that we believe have higher growth rates than other end-market segments served by the overall semiconductor industry.

          Our broad product line includes:

	•		Discrete semiconductor products, including performance Schottky rectifiers; performance Schottky diodes; Zener diodes and performance Zener diodes, including tight tolerance and low operating current types; standard, fast, super-fast and ultra-fast recovery rectifiers; bridge rectifiers; switching diodes; small signal bipolar transistors; prebiased transistors; MOSFETs; thyristor surge protection devices; and transient voltage suppressors;
	•		Complex high-density diode, transistor and mixed technology arrays, in multi-pin ultra-miniature surface-mount packages, including customer specific and function specific arrays;
	•		Silicon wafers used in manufacturing these products; and
	•		Analog, including power management devices and Hall effect sensors.

          Our semiconductor products are an essential building-block of electronic circuit design and are available in thousands of permutations varying according to voltage, current, power handling capability and switching speed.

          Our complex diode and transistor arrays help bridge the gap between discrete semiconductors and integrated circuits. Arrays consist of multiple discrete semiconductor devices housed in a single package. Our discrete surface-mount devices, which are components that can be attached to the surface of a substrate with solder, target end-equipment categories with critical needs to minimize size while maintaining power efficiency and performance.

          The following table lists the end-markets, some of the applications in which our products are used, and the percentage of net sales for each end-market for the last three years:

End Markets		2006				2007				2008				End product applications

PRODUCT PACKAGING

          Our device packaging technology primarily includes a wide variety of surface-mount packages. Our focus on the development of smaller, more thermally efficient, and increasingly integrated packaging, is a critical component of our product development. We provide a comprehensive offering of miniature and sub-miniature packaging, enabling us to fit components into smaller and more efficient packages, while maintaining the same device functionality and power handling capabilities. Smaller packaging provides a reduction in the height, weight and board space required for our components, and is well suited for battery-powered, hand-held and wireless consumer applications such as digital audio players, notebook computers, flat-panel displays, mobile handsets, digital cameras and set-top boxes.

CUSTOMERS

          We serve over 230 direct customers worldwide, which consist of OEMs and EMS providers. Additionally, we have approximately 70 distributor customers worldwide, through which we indirectly serve over 10,000 customers. Our customers include: (i) industry leading OEMs in a broad range of industries, such as Bose Corporation, Honeywell International, Inc., Cisco Systems, Inc., LG Electronics, Inc., Motorola, Inc., Quanta Computer, Inc., Sagem Communication, Delta Electronics, Hella, Ltd., and Samsung Electronics Co., Ltd.; (ii) leading EMS providers, such as Celestica, Inc., Flextronics International, Ltd., Hon Hai Precision Industry Co., Ltd., Inventec Corporation, Jabil Circuit, Inc., and Sanmina-SCI Corporation, who build end-market products incorporating our semiconductors for companies such as Apple Computer, Inc., Dell, Inc., EMC Corporation, Intel Corporation, Microsoft Corporation, Thompson, Inc. and Roche Diagnostics; and (iii) leading distributors such as Arrow Electronics, Inc., Avnet, Inc., Future Electronics, Yosun Industrial Corporation, Zenitron Corporation and Rutronic. For the years of 2006, 2007 and 2008, our OEM and EMS customers together accounted for 54.2%, 61.1% and 56.6%, respectively, of our net sales.

          For the years ended December 31, 2006, 2007 and 2008, Lite-On Semiconductor Corporation (LSC), which is also our largest stockholder, (owning approximately 20.2% of our Common Stock as of December 31, 2008), and a member of the Lite-On Group of companies, accounted for approximately 6.5%, 6.2% and 3.5%, respectively, of our net sales. No customer accounted for 10% or more of our net sales in 2006, 2007 and 2008. Also, 13.0%, 11.3% and 9.6% of our net sales were from the subsequent sale of products we purchased from LSC in 2006, 2007 and 2008, respectively. See “Business — Certain relationships and related party transactions” for additional information.

          We believe that our close relationships with our OEM and EMS customers have provided us with deeper insight into our customers’ product needs than other manufacturers who we believe depend to a greater extent on indirect sales through distributors. In addition to seeking to expand relationships with our existing customers, our strategy is to pursue new customers and diversify our customer base by focusing on leading global consumer electronics companies and their EMS providers and distributors.

          We generally warrant that products sold to our customers will, at the time of shipment, be free from defects in workmanship and materials and conform to our approved specifications. Subject to certain exceptions, our standard warranty extends for a period of one year from the date of shipment. Warranty expense has not been significant. Generally, our customers may cancel orders on short notice without incurring a significant penalty.

          Many of our customers are based in Asia or have manufacturing facilities in Asia. Net sales by country consists of sales to customers in that country based on the country to which products are billed. For the year ended December 31, 2008, 30.0%, 27.4%, 19.8%, and 22.8% of our net sales were derived from China, Taiwan, the U.S. and all other markets, respectively, compared to 38.9%, 25.6%, 20.3%, and 15.2% in 2007, respectively. We anticipate the percentage of net sales shipped to customers in Asia to increase as the trend towards manufacturing in Asia continues. In addition, as a result of the Zetex acquisition we will begin to add significant revenue in Europe.

SALES AND MARKETING

          We market and sell our products worldwide through a combination of direct sales and marketing personnel, independent sales representatives and distributors. We have direct sales personnel in the U.S., England, France, Germany, Taiwan and China. We also have independent sales representatives in the U.S., Japan, Korea, and Europe. We currently have distributors in the U.S., Europe and Asia.

          As of December 31, 2008, our direct global sales and marketing organization consisted of approximately 200 employees operating out of 18 offices. We have sales and marketing offices or representatives in Taipei, Taiwan; Shanghai and Shenzhen, China; Hong Kong; Beauzelle, France; and Munich, Germany; and we have 6 regional sales offices in the U.S. As of December 31, 2008, we also had approximately 17 independent sales representative firms marketing our products.

          Our marketing group focuses on our product strategy, product development road map, new product introduction process, demand assessment and competitive analysis. Our marketing programs include participation in industry tradeshows, technical conferences and technology seminars, sales training and public relations. The marketing group works closely with our sales and research and development groups to align our product development road map. The marketing group coordinates its efforts with our product development, operations and sales groups, as well as with our customers, sales representatives and distributors. We support our customers through our field application engineering and customer support organizations.

          To support our global customer-base, our website is language-selectable into English, Chinese and Korean, giving us an effective marketing tool for worldwide markets. With its extensive online product catalog with advanced search capabilities, our website facilitates quick and easy product selection. Our website, www.diodes.com, provides easy access to our worldwide sales contacts and customer support, as well as incorporates a distributor-inventory check to provide component inventory availability

and a small order desk for overnight sample fulfillment. In addition, our website provides investors access to our financial and corporate governance information.

MANUFACTURING OPERATIONS AND FACILITIES

          We operate two manufacturing facilities located in Shanghai, China, one in Neuhaus, Germany and a joint venture facility in Chengdu, China, and our wafer fabrication facilities are in Kansas City, Missouri and Oldham, England. Our facilities in Shanghai perform packaging, assembly and testing functions, our joint venture facility in Chengdu performs packaging functions, our Kansas City facility is a 5-inch and 6-inch wafer foundry and our Oldham facility is a 6-inch wafer foundry. In 2007, we moved our Taiwan analog probe and testing operations to our Shanghai facilities.

          For the years ended at December 31, 2007 and 2008, we had invested approximately $41.2 million and $30.0 million, respectively, in plant and state-of-the-art equipment in China ($197.3 million total investment in China from inception). Both of our facilities in China manufacture product for sale by our U.S., Europe and Asia operations, and also sell to external customers. For the years ended at December 31, 2007 and 2008, we had invested approximately $8.6 million and $13.5 million, respectively, in equipment for our wafer foundries, including expenses to shut down the 4-inch line and upgrade our 6-inch line in Oldham.

          Silicon wafers are received and inspected in a highly controlled “clean room” environment awaiting the assembly operation. During the first step of assembly, the wafers are sawn with very thin, high speed diamond blades into tiny semiconductor “dice,” numbering as many as 170,000 per 5-inch diameter wafer and 240,000 per 6-inch diameter wafer. Dice are then loaded onto a handler, which automatically places the dice, one by one, onto lead frames, which are package specific, where they are bonded to the lead-frame pad. Next, automatic wire bonders make the necessary electrical connections from the die to the leads of the lead-frame, using micro-thin gold wire for the majority of our products, while some products use copper wire instead. Also, some of our high power devices are clip bonded using copper clips or are aluminum bonded using aluminum bond wires. Then our devices are sent through our fully automated assembly machinery that molds the epoxy case around the die and lead-frame to produce the desired semiconductor product or are molded manually. After a trim, form, test, mark and re-test operation for most products, certain parts such as surface mounted devices are placed into special carrier housings and a cover tape seals the parts in place, while other devices are put into other special packaging. The surface mounted devices are then spooled onto reels or placed into other packaging medium and boxed for shipment.

          Our manufacturing processes use many raw materials, including silicon wafers, copper lead frames, gold wire and other metals, molding compounds and various chemicals and gases. As part of our cost reduction initiatives as discussed in detail in “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Cost Reduction Initiative” in Part II, Item 7 of this Annual Report, we are continuously evaluating our raw material costs in order to reduce our gold consumption while protecting and maintaining product performance. We have no material agreements with any of our suppliers that impose minimum or continuing supply obligations. From time to time, suppliers may extend lead times, limit supplies or increase prices due to capacity constraints or other factors. Although we believe that supplies of the raw materials we use are currently and will continue to be available, shortages could occur in various essential materials due to interruption of supply or increased demand in the industry. See “Risk Factors — We depend on third-party suppliers for timely deliveries of raw materials, parts and equipment, as well as finished products from other manufacturers, and our results of operations could be adversely affected if we are unable to obtain adequate supplies in a timely manner” in Part I, Item 1A of this Annual Report.

          Our corporate headquarters are located in a leased facility in Dallas, Texas. We also lease or own properties around the world for use as sales offices, research and development labs, warehouses and logistic centers. The size and/or location of these properties can change from time to time based on our business requirements. In 2008, we purchased land near Dallas, Texas for approximately $4.9 million, which will be the future site of our corporate headquarters. See “Properties” in Part I, Item 2 of this Annual Report for further details about our leased and owned properties.

BACKLOG

          The amount of backlog to be shipped during any period is dependent upon various factors, and all orders are subject to cancellation or modification, usually with no penalty to the customer. Orders are generally booked from one month to greater than twelve months in advance of delivery. The rate of booking of new orders can vary significantly from month to month. We, and the industry as a whole, have been experiencing a trend towards shorter lead-times, and we expect this trend to continue. The amount of backlog at any date depends upon various factors, including the timing of the receipt of orders, fluctuations in orders of existing product lines, and the introduction of any new lines. Accordingly, we believe that the amount of our backlog at any date is not a particularly useful measure of our future sales. We strive to maintain proper inventory levels to support our customers’ just-in-time order expectations.

PATENTS, TRADEMARKS AND LICENSES

          Historically, patents and trademarks have not been material to our operations, but we expect them to become more important, particularly as they relate to our discrete, analog and packaging technologies.

          Our initial product patent portfolio was primarily composed of discrete technologies. Then, in the late 1990s, our engineers in Shanghai began to research and develop packaging technologies, which produced several important breakthrough and patents, such as the PowerDI^â series of packaging technology to foster our growth in the semiconductor industry.

          We subsequently acquired Anachip Corp. in early 2006, a fables semiconductor company, which initiated our presence in the analog standard product market.

          Then through our APD asset acquisition in late 2006, we acquired the SBR^® patents and trademark. SBR^® is state-of-the-art integrated circuit wafer processing technology that allows the design and manufacture of a device, which is able to integrate and improve the benefits of the two existing rectifier technologies into a single device. The creation of a finite conduction cellular IC, combined with inherent design uniformity has allowed manufacturing costs to be kept competitive with the existing power device technology, and thus produced a breakthrough in rectifier technology.

          Our recent acquisition of Zetex in 2008 subsequently increased our available discrete and analog technologies with valuable patents and trademarks for bipolar transistors and power management products such as LED drivers. LED drivers support a wide range of applications for automotive, safety and security, architecture, and portable lighting and are highly efficient and cost effective.

          Currently, our licensing of patents to other companies is not material. We do, however, license certain product technology from other companies, but we do not consider any of the licensed technology to be material in terms of royalties. We believe the duration and other terms of the licenses are appropriate for our current needs. See “Risk Factors — We may be subject to claims of infringement of third-party intellectual property rights or demands that we license third-party technology, which could result in significant expense and reduction in our intellectual property rights” in Part I, Item 1A of this Annual Report.

COMPETITION

          Numerous semiconductor manufacturers and distributors serve the discrete and analog semiconductor components market, making competition intense. Some of our larger competitors include Fairchild Semiconductor Corporation, Infineon Technologies A.G., International Rectifier Corporation, ON Semiconductor Corporation, Philips Electronics N.V., Rohm Electronics USA, LLC, Toshiba Corporation and Vishay Intertechnology, Inc., many of which have greater financial, marketing, distribution and other resources than us. Accordingly, in response to market conditions, we from time to time may reposition product lines or decrease prices, which may affect our sales of, and profit margins on, such product lines. The price and quality of the product, and our ability to design products and deliver customer service in keeping with the customers’ needs, determine the competitiveness of our products. We believe that our product focus, packaging expertise and our flexibility and ability to quickly adapt to customer needs affords us competitive advantages. See “Risk Factors — The semiconductor business is highly competitive, and increased competition may harm our business and our operating results” in Part I, Item 1A of this Annual Report.

ENGINEERING AND RESEARCH AND DEVELOPMENT

          Our engineering and research and development groups consist of applications, technical marketing, and product development engineers who assist in determining the direction of our future product lines. Their primary function is to work closely with market-leading customers to further refine, expand and improve our product range within our product types and packages. In addition, customer requirements and acceptance of new package types are assessed and new, higher-density and more energy-efficient packages are developed to satisfy customers’ needs. Working with customers to integrate multiple types of technologies within the same package, our applications engineers strive to reduce the required number of components and, thus, circuit board size requirements of a device, while increasing the functionality of the component technology.

          Product engineers work directly with our semiconductor wafer design and process engineers who develop die designs needed for products that precisely match our customers’ requirements. Direct contact with our manufacturing facilities allows the manufacturing of products that are in line with current technical requirements. We have the capability to capture the customers’ electrical and packaging requirements through their product development engineers, and then transfer those requirements to our research and development and engineering department, so that the customers’ requirements can be translated, designed, and manufactured with full control, even to the elemental silicon level.

          For the years ended December 31, 2006, 2007 and 2008, Company-sponsored investment in research and development activities was $8.3 million, $13.5 million and $22.5 million, respectively. As a percentage of net sales, research and development expense was 2.4%, 3.4% and 5.2% for 2006, 2007 and 2008, respectively. The increase in 2008 was mainly due to research and development activities associated with the acquisition of Zetex. Given the current economic conditions, we anticipate research and development expense to remain relatively flat in absolute dollars, but to increase as a percentage of net sales due to the lower expected net sales.

EMPLOYEES

          As of December 31, 2008, we employed a total of 3,067 employees, of which 2,215 of our employees were in Asia, 269 were in the United States and 583 were in Europe. None of our employees in Asia or the United States are subject to a collective bargaining agreement but a majority of our employees in Europe are covered by local labor agreements. We consider our relations with our employees to be satisfactory. See “Risk Factors — We may fail to attract or retain the qualified technical, sales, marketing and management personnel required to operate our business successfully” in Part I, Item 1A of this Annual Report.

          Due to the current economic conditions, we have reduced our number of employees during the first quarter of 2009. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations -Cost reduction initiative” in Part II, Item 7 of this Annual Report for additional information.

ENVIRONMENTAL MATTERS

          We are subject to a variety of U.S. Federal, state, local and foreign governmental laws, rules and regulations related to the use, storage, handling, discharge or disposal of certain toxic, volatile or otherwise hazardous chemicals used in our manufacturing process both in the U.S. and England where our wafer fabrication facilities are located, and in China and Germany where our assembly, test and packaging facilities are located. Any of these regulations could require us to acquire equipment or to incur substantial other costs to comply with environmental regulations or remediate problems. For the years ended December 31, 2006, 2007 and 2008, our capital expenditures for environmental controls have not been material. As of December 31, 2008, there were no known environmental claims or recorded liabilities. See “Risk Factors — We are subject to many environmental laws and regulations that could affect our operations or result in significant expenses” in Part I, Item 1A of this Annual Report.

CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS

          We conduct business with one related party company, Lite-On Semiconductor Corporation and its subsidiaries and affiliates (“LSC”). LSC is our largest stockholder, owning approximately 20.2% of our outstanding Common Stock as of December 31, 2008, and is a member of the Lite-On Group of companies. C.H. Chen, our former President and Chief Executive Officer, and Vice Chairman of our Board of Directors, is also Vice Chairman of LSC. M.K. Lu, a member of our Board of Directors until May 2007, was President of LSC. In addition, Raymond Soong, the Chairman of our Board of Directors, is Chairman of LSC, and is the Chairman of Lite-On Technology Corporation, a significant shareholder of LSC.

          We also conduct business with one significant company, Keylink International (B.V.I) Inc., and its subsidiaries and affiliates (“Keylink”). Keylink is our 5% joint venture partner in our Shanghai manufacturing facilities.

          The Audit Committee of our Board of Directors reviews all related party transactions for potential conflict of interest situations on an ongoing basis, in accordance with such procedures as the Audit Committee may adopt from time to time. We believe that all related party transactions are on terms no less favorable to us than would be obtained from unaffiliated third parties.

          We sold silicon wafers to LSC totaling 6.5%, 6.2% and 3.5% of total sales for the years ended December 31, 2006, 2007 and 2008, respectively, making LSC our largest customer. Also for the years ended December 31, 2006, 2007 and 2008, 13.0%, 11.3% and 9.6%, respectively, of our net sales were from discrete semiconductor products purchased from LSC for subsequent sale by us, making LSC our largest outside supplier. We also rent warehouse space in Hong Kong from a member of the Lite-On Group, which also provides us with warehousing services at that location. For 2006, 2007 and 2008, we reimbursed this entity in aggregate amounts of $0.5 million, $0.5 million and $0.7 million, respectively, for these services. We believe that such transactions are on terms no less favorable to us than could be obtained from unaffiliated third parties. See “Risk Factors — We receive a significant portion of our net sales from a single customer. In addition, this customer is also our largest external supplier and is a related party. The loss of this customer or supplier could harm our business and results of operations” in Part I, Item 1A of this Annual Report.

          We sell product to, and purchase inventory from, companies owned by Keylink. We sold silicon wafers to companies owned by Keylink totaling 0.4%, 0.6% and 0.8% of total sales for the years ended December 31, 2006, 2007 and 2008, respectively. Also for the years ended December 31, 2006, 2007 and 2008, 2.3%, 1.5% and 1.3%, respectively, of our net sales were from discrete semiconductor products purchased from companies owned by Keylink. In addition, we lease our Shanghai manufacturing facilities from, and subcontract a portion of their manufacturing process (metal plating and environmental services) to, Keylink, and also pay a consulting fee to a Keylink affiliated company. The aggregate amounts for these services for the years ended December 31, 2006, 2007 and 2008 were $7.9 million, $9.4 million and $10.5 million, respectively. We believe such transactions are on terms no less favorable to us than could be obtained from unaffiliated third parties.

          When we acquired Anachip Corp., we inherited a wafer purchase agreement between Anachip Corp. and LSC, pursuant to which LSC would sell to Anachip Corp., according to Anachip Corp.’s requirements, during the three year period ending on December 31, 2008. Anachip Corp. purchased the wafers on terms (including purchase price, delivery schedule, and payment terms) no less favorable to Anachip Corp. than those terms on which Anachip Corp. purchased such wafers from LSC at the time of the acquisition; provided, however, that the purchase price would be the lower of the current price or the most favorable customer pricing. If the price of raw wafers increased by more than 20% within any six-month period, Anachip Corp. and LSC would renegotiate in good faith the price of wafers to reflect the cost increase. Although this contract was not renewed, Anachip Corp. continues to purchase wafers from LSC.

          During 2008, LSC sold 0.3 million shares, reducing its holdings of our Common Stock to 8.4 million shares (20.2% of our outstanding Common Stock as of December 31, 2008). We did not receive any of the proceeds from their sale of our Common Stock

SEASONALITY

          Historically, our net sales have been affected by the cyclical nature of the semiconductor industry and the seasonal trends of related end markets, specifically in the consumer and computing markets.

RISKS RELATED TO OUR BUSINESS

Global economic weakness and the current financial market uncertainty has had, and is expected to continue to have through at least 2009, a material adverse effect on our business.

          The current global economic weakness, including the potential for a significant and prolonged global economic recession, has led to lower consumer discretionary spending and demand for items that incorporate our products in the consumer electronics, computing, industrial, communications and the automotive sectors. The decline in end-user demand has in turn affected our customers’ demand for our products, the ability of our customers to meet their payment obligations, and the likelihood of customers canceling or deferring existing orders. Our revenues and operating results have been, and may continue to be, negatively affected by such actions. The current global economic weakness and financial market uncertainty may last longer than we anticipated or have a greater adverse effect on our business, including our revenues and operating results, than we anticipated.

In the current difficult market conditions, our fixed costs combined with lower revenues have negatively impacted our results.

          The semiconductor industry is characterized by high fixed costs. Notwithstanding our utilization of third-party manufacturing capacity, most of our production requirements are met by our own manufacturing facilities. In difficult economic environments like the one we are currently experiencing, we are generally faced with a decline in the utilization rates of our manufacturing facilities due to decreases in product demand. During such periods, our fabrication plants do not operate at full capacity and the costs associated with this excess capacity are expensed immediately and not capitalized into inventory. By the end of 2008, our utilization rate declined to abnormally low production levels compared to the end of 2007, which resulted in lower gross margins. The market conditions in the future may continue to adversely affect our utilization rates and consequently our future gross margins, and this, in turn, could have a material negative impact on our business, financial condition and results of operations.

Downturns in the highly cyclical semiconductor industry or changes in end-market demand could affect our operating results and financial condition.

          The semiconductor industry is highly cyclical, and periodically experiences significant economic downturns characterized by diminished product demand, production overcapacity and excess inventory, which can result in rapid erosion in average selling prices. From time to time, the semiconductor industry experiences order cancellations and reduced demand for products, resulting in significant revenue declines, due to excess inventories at computer and telecommunications equipment manufacturers and general economic conditions, especially in the technology sector. The market for semiconductors may experience renewed, and possibly more severe and prolonged downturns in the future, which may harm our results of operations and reduce the value of our business.

          In addition, we operate in a few narrow markets of the broader semiconductor market and, as a result, cyclical fluctuations may affect these segments to a greater extent than they do to the broader semiconductor market. This may cause us to experience greater fluctuations in our results of operations than compared to some of our broad line semiconductor manufacturer competitors. In addition, we may experience significant changes in our profitability as a result of variations in sales, changes in product mix, changes in end-user markets and the costs associated with the introduction of new products. The markets for our products depend on continued demand in the consumer electronics, computer, industrial, communications and automotive sectors. These end-user markets also tend to be cyclical and may also experience changes in demand that could adversely affect our operating results and financial condition.

The semiconductor business is highly competitive, and increased competition may harm our business and our operating results.

          The semiconductor industry in which we operate is highly competitive. We expect intensified competition from existing competitors and new entrants. Competition is based on price, product performance, product availability, quality, reliability and customer service. We compete in various markets with companies of various sizes, many of which are larger and

have greater resources or capabilities as it relates to financial, marketing, distribution, brand name recognition, research and development, manufacturing and other resources than we have. As a result, they may be better able to develop new products, market their products, pursue acquisition candidates and withstand adverse economic or market conditions. Most of our current major competitors are broad line semiconductor manufacturers who often have a wider range of product types and technologies than we do. In addition, companies not currently in direct competition with us may introduce competing products in the future. Some of our current major competitors are Fairchild Semiconductor Corporation, Infineon Technologies A.G., International Rectifier Corporation, ON Semiconductor Corporation, Philips Electronics N.V., Rohm Electronics USA, LLC, Toshiba Corporation and Vishay Intertechnology, Inc. We may not be able to compete successfully in the future, and competitive pressures may harm our financial condition or our operating results.

We receive a significant portion of our net sales from a single customer. In addition, this customer is also our largest external supplier and is a related party. The loss of this customer or supplier could harm our business and results of operations.

          In 2007 and 2008, LSC, our largest stockholder and one of our largest customers, accounted for 6.2% and 3.5%, respectively, of our net sales. LSC is also our largest supplier, providing us with discrete semiconductor products for subsequent sale by us, which represented approximately 11.3% and 9.6%, respectively, of our net sales, in 2007 and 2008. The loss of LSC as either a customer or a supplier, or any significant reductions in either the amount of products it supplies to us, or the volume of orders it places with us, could materially harm our business and results of operations.

Delays in initiation of production at new facilities, implementing new production techniques or resolving problems associated with technical equipment malfunctions could adversely affect our manufacturing efficiencies.

          Our manufacturing efficiency has been and will be an important factor in our future profitability, and we may not be able to maintain or increase our manufacturing efficiency. Our manufacturing and testing processes are complex, require advanced and costly equipment and are continually being modified in our efforts to improve yields and product performance. Difficulties in the manufacturing process can lower yields. Technical or other problems could lead to production delays, order cancellations and lost revenue. In addition, any problems in achieving acceptable yields, construction delays, or other problems in upgrading or expanding existing facilities, building new facilities, problems in bringing other new manufacturing capacity to full production or changing our process technologies, could also result in capacity constraints, production delays and a loss of future revenues and customers. Our operating results also could be adversely affected by any increase in fixed costs and operating expenses related to increases in production capacity if net sales do not increase proportionately, or in the event of a decline in demand for our products.

          Our wafer fabrication facilities are located in Kansas City, Missouri, and Oldham, England, while our facilities in Shanghai, China provide assembly, test and packaging capabilities. Any disruption of operations at these facilities could have a material adverse effect on our business, financial condition and results of operations.

We are and will continue to be under continuous pressure from our customers and competitors to reduce the price of our products, which could adversely affect our growth and profit margins.

          Prices for our products tend to decrease over their life cycle. There is substantial and continuing pressure from customers to reduce the total cost of purchasing our products. To remain competitive and retain our customers and gain new ones, we must continue to reduce our costs through product and manufacturing improvements. We must also strive to minimize our customers’ shipping and inventory financing costs and to meet their other goals for rationalization of supply and production. We experienced an increase in average selling prices (“ASP”) for our products of 12.1% in 2006, a decrease of 6.8% in 2007 and an increase of 5.6% in 2008 (due primarily to higher ASPs for Zetex products). At times, we may be required to sell our products at ASP’s below our manufacturing cost or purchase price in order to remain competitive. Our growth and the profit margins of our products will suffer if we cannot effectively continue to reduce our costs and keep our product prices competitive.

Our customers require our products to undergo a lengthy and expensive qualification process without any assurance of product sales

          Prior to purchasing our products, our customers require that our products undergo an extensive qualification process, which involves rigorous reliability testing. This qualification process may continue for six months or longer. However, qualification of a product by a customer does not ensure any sales of the product to that customer. Even after successful qualification and sales of a product to a customer, a subsequent revision to the device, changes in the device’s manufacturing process or the selection of a new supplier by us may require a new qualification process, which may result in delays and in us holding excess or obsolete inventory. After our products are qualified, it can take an additional six months or more before the customer commences volume production of components or devices that incorporate our products.

Despite these uncertainties, we devote substantial resources, including design, engineering, sales, marketing and management efforts, toward qualifying our products with customers in anticipation of sales. If we are unsuccessful or delayed in qualifying any of our products with a customer, such failure or delay would preclude or delay sales of such product to the customer, which may impede our growth and cause our business to suffer.

Our customer orders are subject to cancellation or modification usually with no penalty. High volumes of order cancellation or reductions in quantities ordered could adversely affect our results of operations and financial condition.

          All of our customer orders are subject to cancellation or modification, usually with no penalty to the customer. Orders are generally made on a purchase order basis, rather than pursuant to long-term supply contracts, and are booked from one to twelve months in advance of delivery. The rate of booking new orders can vary significantly from month to month. We, and the semiconductor industry as a whole, are experiencing a trend towards shorter lead-times, which is the amount of time between the date a customer places an order and the date the customer requires shipment. Furthermore, our industry is subject to rapid changes in customer outlook and periods of excess inventory due to changes in demand in the end markets our industry serves. As a result, many of our purchase orders are revised, and may be cancelled, with little or no penalty and with little or no notice. However, we must still commit production and other resources to fulfilling these orders even though they may ultimately be cancelled. If a significant number of orders are cancelled or product quantities ordered are reduced, and we are unable to timely generate replacement orders, we may build up excess inventory and our results of operations and financial condition may suffer.

Production at our manufacturing facilities could be disrupted for a variety of reasons, which could prevent us from producing enough of our products to maintain our sales and satisfy our customers’ demands.

          A disruption in production at our manufacturing facilities could have a material adverse effect on our business. Disruptions could occur for many reasons, including fire, natural disasters, weather, unplanned maintenance or other manufacturing problems, disease, strikes, transportation interruption, government regulation or terrorism. Alternative facilities with sufficient capacity or capabilities may not be available, may cost substantially more or may take a significant time to start production, each of which could negatively affect our business and financial performance. If one of our key manufacturing facilities is unable to produce our products for an extended period of time, our sales may be reduced by the shortfall caused by the disruption, and we may not be able to meet our customers’ needs, which could cause them to seek other suppliers. Such disruptions could have an adverse effect on our results of operations in future reporting periods.

New technologies could result in the development of new products by our competitors and a decrease in demand for our products, and we may not be able to develop new products to satisfy changes in demand, which could result in a decrease in net sales and loss of market share.

          Our product range and new product development program is focused on discrete and analog semiconductor products. Our failure to develop new technologies, or anticipate or react to changes in existing technologies, either within or outside of the semiconductor market, could materially delay development of new products, which could result in a decrease in our net sales and a loss of market share to our competitors. The semiconductor industry is characterized by rapidly changing technologies and industry standards, together with frequent new product introductions. This includes the development of new types of technology or the improvement of existing technologies, such as analog and digital technologies that compete with, or seek to replace discrete semiconductor technology. Our financial performance depends on our ability to design, develop, manufacture, assemble, test, market and support new products and product enhancements on a timely and cost-effective basis. New products often command higher prices and, as a result, higher profit margins. We may not successfully identify new product opportunities or develop and bring new products to market or succeed in selling them into new customer applications in a timely and cost-effective manner.

          Products or technologies developed by other companies may render our products or technologies obsolete or noncompetitive and, since we operate primarily in a narrower segment of the broader semiconductor industry, this may have a greater effect on us than it would if we were a broad-line semiconductor manufacturer with a wider range of product types and technologies. Many of our competitors are larger and more established international companies with greater engineering and research and development resources than us. Our failure to identify or capitalize on any fundamental shifts in technologies in our product markets, relative to our competitors, could harm our business, have a material adverse effect on our competitive position within our industry and harm our relationships with our customers. In addition, to remain competitive, we must continue to reduce package sizes, improve manufacturing yields and expand our sales. We may not be able to accomplish these goals, which could harm our business.

We may be adversely affected by any disruption in our information technology systems.

          Our operations are dependent upon our information technology systems, which encompass all of our major

business functions. We rely upon such information technology systems to manage and replenish inventory, to fill and ship customer orders on a timely basis, to coordinate our sales activities across all of our products and services and to coordinate our administrative activities. A substantial disruption in our information technology systems for any prolonged time period (arising from, for example, system capacity limits from unexpected increases in our volume of business, outages or delays in our service) could result in delays in receiving inventory and supplies or filling customer orders and adversely affect our customer service and relationships. Our systems might be damaged or interrupted by natural or man-made events or by computer viruses, physical or electronic break-ins and similar disruptions affecting the global Internet. There can be no assurance that such delays, problems, or costs will not have a material adverse effect on our financial condition, results of operations and cash flows.

          As our operations grow in both size and scope, we will continuously need to improve and upgrade our systems and infrastructure while maintaining the reliability and integrity of our systems and infrastructure. The expansion of our systems and infrastructure will require us to commit substantial financial, operational and technical resources before the volume of our business increases, with no assurance that the volume of business will increase. In particular, we have upgraded our financial reporting system and are currently seeking to upgrade other information technology systems. These and any other upgrades to our systems and information technology, or new technology, now and in the future, will require that our management and resources be diverted from our core business to assist in compliance with those requirements. There can be no assurance that the time and resources our management will need to devote to these upgrades, service outages or delays due to the installation of any new or upgraded technology (and customer issues therewith), or the impact on the reliability of our data from any new or upgraded technology will not have a material adverse effect on our business, financial condition or results of operations.

          All of our operations, other than Diodes FabTech Inc. and Diodes Zetex Limited, operate on a single technology platform. To manage our international operations efficiently and effectively, we rely heavily on our Enterprise Resource Planning (ERP) system, internal electronic information and communications systems and on systems or support services from third parties. Any of these systems are subject to electrical or telecommunications outages, computer hacking or other general system failure. It is also possible that future acquisitions operate on ERP systems different from ours and that we could face difficulties in integrating operational and accounting functions of new acquisitions. Difficulties in upgrading or expanding our ERP system or system-wide or local failures that affect our information processing could have material adverse effects on our business, financial condition, results of operations and cash flows.

We may be subject to claims of infringement of third-party intellectual property rights or demands that we license third-party technology, which could result in significant expense and reduction in our intellectual property rights.

          The semiconductor industry is characterized by vigorous protection and pursuit of intellectual property rights. From time to time, third parties have asserted, and may in the future assert, patent, copyright, trademark and other intellectual property rights to technologies that are important to our business and have demanded, and may in the future demand, that we license their patents and technology. Any litigation to determine the validity of allegations that our products infringe or may infringe these rights, including claims arising through our contractual indemnification of our customers, or claims challenging the validity of our patents, regardless of its merit or resolution, could be costly and divert the efforts and attention of our management and technical personnel. We may not prevail in litigation given the complex technical issues and inherent uncertainties in intellectual property litigation. If litigation results in an adverse ruling we could be required to:

	•		pay substantial damages for past, present and future use of the infringing technology;
	•		cease the manufacture, use or sale of infringing products;
	•		discontinue the use of infringing technology;
	•		expend significant resources to develop non-infringing technology;
	•		pay substantial damages to our customers or end-users to discontinue use or replace infringing technology with non-infringing technology;
	•		license technology from the third party claiming infringement, which license may not be available on commercially reasonable terms, or at all; or
	•		relinquish intellectual property rights associated with one or more of our patent claims, if such claims are held invalid or otherwise unenforceable.

We depend on third-party suppliers for timely deliveries of raw materials, parts and equipment, as well as finished products from other manufacturers, and our results of operations could be adversely affected if we are unable to obtain adequate supplies in a timely manner.

          Our manufacturing operations depend upon obtaining adequate supplies of raw materials, parts and equipment on a timely basis from third parties. Our results of operations could be adversely affected if we are unable to obtain adequate supplies of raw materials, parts and equipment in a timely manner or if the costs of raw materials, parts or equipment were to

increase significantly. Our business could also be adversely affected if there is a significant degradation in the quality of raw materials used in our products, or if the raw materials give rise to compatibility or performance issues in our products, any of which could lead to an increase in customer returns or product warranty claims. Although we maintain rigorous quality control systems, errors or defects may arise from a supplied raw material and be beyond our detection or control. Any interruption in, or change in quality of, the supply of raw materials, parts or equipment needed to manufacture our products could adversely affect our business and harm our results of operations and our reputation with our customers.

          In addition, we sell finished products from other manufacturers. Our business could also be adversely affected if there is a significant degradation in the quality of these products. From time to time, such manufacturers may extend lead-times, limit supplies or increase prices due to capacity constraints or other factors. We have no long-term purchase contracts with any of these manufacturers and, therefore, have no contractual assurances of continued supply, pricing or access to finished products that we sell, and any such manufacturer could discontinue supplying to us at any time. Additionally, some of our suppliers of finished products or wafers compete directly with us and may in the future choose not to supply products to us.

If we do not succeed in continuing to vertically integrate our business, we will not realize the cost and other efficiencies we anticipate and our ability to compete, profit margins and results of operations may suffer.

          We are continuing to vertically integrate our business. Key elements of this strategy include continuing to expand the reach of our sales organization, expand our manufacturing capacity, expand our wafer foundry and research and development capability and expand our marketing, product development, package development and assembly/testing operations in company-owned facilities or through the acquisition of established contractors. There are certain risks associated with our vertical integration strategy, including:

	•		difficulties associated with owning a manufacturing business, including, but not limited to, the maintenance and management of manufacturing facilities, equipment, employees and inventories and limitations on the flexibility of controlling overhead;
	•		difficulties in continuing expansion of our operations in Asia and Europe, because of the distance from our U.S. headquarters and differing regulatory and cultural environments;
	•		the need for skills and techniques that are outside our traditional core expertise;
	•		less flexibility in shifting manufacturing or supply sources from one region to another;
	•		even when independent suppliers offer lower prices, we would continue to acquire wafers from our captive manufacturing facility, which may result in us having higher costs than our competitors;
	•		difficulties developing and implementing a successful research and development team; and
	•		difficulties developing, protecting, and gaining market acceptance of, our proprietary technology.

          The risks of becoming a fully integrated manufacturer are amplified in an industry-wide slowdown because of the fixed costs associated with manufacturing facilities. In addition, we may not realize the cost, operating and other efficiencies that we expect from continued vertical integration. If we fail to successfully vertically integrate our business, our ability to compete, profit margins and results of operations may suffer.

Part of our growth strategy involves identifying and acquiring companies with complementary product lines or customers. We may be unable to identify suitable acquisition candidates or consummate desired acquisitions and, if we do make any acquisitions, we may be unable to successfully integrate any acquired companies with our operations.

          A significant part of our growth strategy involves acquiring companies with complementary product lines, customers or other capabilities. For example, (i) in fiscal year 2000, we acquired Diodes FabTech Inc., a wafer fabrication company, in order to have our own wafer manufacturing capabilities, (ii) in January 2006, we acquired Anachip Corp. as an entry into standard logic markets, (iii) in November 2006, we acquired the net operating assets of APD Semiconductor and (iv) in June 2008, we acquired Zetex plc. While we do not currently have any agreements or commitments in place with respect to any material acquisitions, we are in various stages of preliminary discussions, and we intend to continue to expand and diversify our operations by making further acquisitions. However, we may be unsuccessful in identifying suitable acquisition candidates, or we may be unable to consummate a desired acquisition. To the extent we do make acquisitions, if we are unsuccessful in integrating these companies or their operations or product lines with our operations, or if integration is more difficult than anticipated, we may experience disruptions that could have a material adverse effect on our business, financial condition and results of operations. In addition, we may not realize all of the benefits we anticipate from any such acquisitions. Some of the risks that may affect our ability to integrate or realize any anticipated benefits from acquisitions that we may make include those associated with:

	•		unexpected losses of key employees or customers of the acquired company;
	•		bringing the acquired company’s standards, processes, procedures and controls into conformance with our operations;

	•		coordinating our new product and process development;
	•		hiring additional management and other critical personnel;
	•		increasing the scope, geographic diversity and complexity of our operations;
	•		difficulties in consolidating facilities and transferring processes and know-how;
	•		difficulties in reducing costs of the acquired entity’s business;
	•		diversion of management’s attention from the management of our business; and
	•		adverse effects on existing business relationships with customers.

          See Part I, Item 3 of this Annual Report for additional information regarding our current legal proceedings.

We are subject to many environmental laws and regulations that could affect our operations or result in significant expenses.

          We are subject to a variety of U.S. Federal, state, local and foreign governmental laws, rules and regulations related to the use, storage, handling, discharge or disposal of certain toxic, volatile or otherwise hazardous chemicals used in our manufacturing process both in the United States and England where our wafer fabrication facilities are located, in China and Germany where our assembly, test and packaging facilities are located, and in Taiwan (where our analog products were produced through 2007). Some of these regulations in the United States include the Federal Clean Water Act, Clean Air Act, Resource Conservation and Recovery Act, Comprehensive Environmental Response, Compensation, and Liability Act and similar state statutes and regulations. Any of these regulations could require us to acquire equipment or to incur substantial other expenses to comply with environmental regulations. If we were to incur such additional expenses, our product costs could significantly increase, materially affecting our business, financial condition and results of operations. Any failure to comply with present or future environmental laws, rules and regulations could result in fines, suspension of production or cessation of operations, any of which could have a material adverse effect on our business, financial condition and results of operations. Our operations affected by such requirements include, among others: the disposal of wastewater containing residues from our manufacturing operations through publicly operated treatment works or sewer systems, and which may be subject to volume and chemical discharge limits and may also require discharge permits; and the use, storage and disposal of materials that may be classified as toxic or hazardous. Any of these may result in, or may have resulted in, environmental conditions for which we could be liable.

          Some environmental laws impose liability, sometimes without fault, for investigating or cleaning up contamination on, or emanating from, our currently or formerly owned, leased or operated properties, as well as for damages to property or natural resources and for personal injury arising out of such contamination. Such liability may also be joint and several, meaning that we could be held responsible for more than our share of the liability involved, or even the entire liability. In addition, the presence of environmental contamination could also interfere with ongoing operations or adversely affect our ability to sell or lease our properties. Environmental requirements may also limit our ability to identify suitable sites for new or expanded plants. Discovery of contamination for which we are responsible, the enactment of new laws and regulations, or changes in how existing requirements are enforced, could require us to incur additional costs for compliance or subject us to unexpected liabilities.

Our products may be found to be defective and, as a result, product liability claims may be asserted against us, which may harm our business and our reputation with our customers.

          Our products are typically sold at prices that are significantly lower than the cost of the equipment or other goods in which they are incorporated. For example, our products that are incorporated into a personal computer may be sold for several cents, whereas the computer maker might sell the personal computer for several hundred dollars. Although we maintain rigorous quality control systems, we shipped approximately 14.5 billion, 18.1 billion and 18.5 billion individual semiconductor devices in years ended at December 31, 2006, 2007 and 2008, respectively, to customers around the world, and in the ordinary course of our business, we receive warranty claims for some of these products that are defective, or that do not perform to published specifications. Since a defect or failure in our products could give rise to failures in the end products that incorporate them (and consequential claims for damages against our customers from their customers), we may face claims for damages that are disproportionate to the revenues and profits we receive from the products involved. In addition, our ability to reduce such liabilities may be limited by the laws or the customary business practices of the countries where we do business. Even in cases where we do not believe we have legal liability for such claims, we may choose to pay for them to retain a customer’s business or goodwill or to settle claims to avoid protracted litigation. Our results of operations and business could be adversely affected as a result of a significant quality or performance issue in our products, if we are required or choose to pay for the damages that result. Although we currently have product liability insurance, we may not have sufficient insurance coverage, and we may not have sufficient resources, to satisfy all possible product liability claims. In addition, any perception that our products are defective would likely result in reduced sales of our products, loss of customers and harm to our business and reputation.

We may fail to attract or retain the qualified technical, sales, marketing and management personnel required to operate our business successfully.

          Our future success depends, in part, upon our ability to attract and retain highly qualified technical, sales, marketing and managerial personnel. Personnel with the necessary expertise are scarce and competition for personnel with these skills is intense. We may not be able to retain existing key technical, sales, marketing and managerial employees or be successful in attracting, assimilating or retaining other highly qualified technical, sales, marketing and managerial personnel in the future. For example, we have faced, and continue to face, intense competition for qualified technical and other personnel in Shanghai, China, where our assembly, test and packaging facilities are located. A number of U.S. and multi-national corporations, both in the semiconductor industry and in other industries, have recently established and are continuing to establish factories and plants in Shanghai, China, and the competition for qualified personnel has increased significantly as a result. If we are unable to retain existing key employees or are unsuccessful in attracting new highly qualified employees, our business, financial condition and results of operations could be materially and adversely affected.

We may not be able to maintain our growth or achieve future growth and such growth may place a strain on our management and on our systems and resources.

          Our ability to successfully grow our business within the discrete and analog semiconductor markets requires effective planning and management. Our past growth, and our targeted future growth, may place a significant strain on our management and on our systems and resources, including our financial and managerial controls, reporting systems and procedures. In addition, we will need to continue to train and manage our workforce worldwide. If we are unable to effectively plan and manage our growth effectively, our business and prospects will be harmed and we will not be able to maintain our profit growth or achieve future growth.

Our business may be adversely affected by obsolete inventories as a result of changes in demand for our products and change in life cycles of our products.

          The life cycles of some of our products depend heavily upon the life cycles of the end products into which devices are designed. These types of end-market products with short life cycles require us to manage closely our production and inventory levels. Inventory may also become obsolete because of adverse changes in end-market demand such as the recent drop in demand of our products due to the global economic downturn. We may in the future be adversely affected by obsolete or excess inventories which may result from unanticipated changes in the estimated total demand for our products or the estimated life cycles of the end products into which our products are designed. In addition, some customers restrict how far back the date of manufacture for our products can be and certain customers may stop ordering products from us and go out of business due to the adverse economic conditions; therefore, some of our products inventory may become obsolete, and thus, adversely affect our results of operations.

If OEMs do not design our products into their applications, a portion of our net sales may be adversely affected.

          We expect an increasingly significant portion of net sales will come from products we design specifically for our customers. However, we may be unable to achieve these design wins. In addition, a design win from a customer does not necessarily guarantee future sales to that customer. Without design wins from OEMs, we would only be able to sell our products to these OEMs as a second source, which usually means we are only able to sell a limited amount of product to them. Once an OEM designs another supplier’s semiconductors into one of its product platforms, it is more difficult for us to achieve future design wins with that OEM’s product platform because changing suppliers involves significant cost, time, effort and risk to an OEM. Achieving a design win with a customer does not ensure that we will receive significant revenues from that customer and we may be unable to convert design into actual sales. Even after a design win, the customer is not obligated to purchase our products and can choose at any time to stop using our products, if, for example, its own products are not commercially successful.

We are subject to interest rate risk that could have an adverse effect on our cost of working capital and interest expenses.

          We have credit facilities with financial institutions in Asia and Europe, as well as other debt instruments, with interest rates equal to LIBOR or similar indices plus a negotiated margin. A rise in interest rates could have an adverse impact upon our cost of working capital and our interest expense. As of December 31, 2008, our outstanding interest-bearing debt was $402.0 million, including $183.5 million senior convertible notes with a fixed rate of 2.25% and $212.7 million under our “no net cost loan.” An increase of 1.0% in interest rates would increase our annual interest rate expense by approximately $0.1 million due to the fact that any increase in interest expense related to our “no net cost loan” will be offset by interest earned on our ARS portfolio.

We had a significant amount of debt following the offering of convertible notes. Our substantial indebtedness could adversely affect our business, financial condition and results of operations and our ability to meet our payment obligations under the notes and or other debt.

          Following the offering of senior convertible notes in October 2006 (“Notes”), we had a significant amount of debt and substantial debt service requirements. As of December 31, 2008, we had $402.0 million of outstanding debt, including $183.5 million Notes with a fixed rate of 2.25% and $212.7 million under our “no net cost loan” with UBS. In addition, $46.5 million is available for future borrowings under our credit facilities in Asia and Europe, and we are permitted under the terms of our debt agreements to incur substantial additional debt.

          This level of debt could have significant consequences on our future operations, including:

	•		making it more difficult for us to meet our payment and other obligations under the notes and our other outstanding debt;
	•		resulting in an event of default if we fail to comply with the financial and other restrictive covenants contained in our debt agreements, which event of default could result in all of our debt becoming immediately due and payable and, in the case of an event of default under our secured debt, such as our senior secured credit facility, could permit the lenders to foreclose on our assets securing that debt;
	•		reducing the availability of our cash flow to fund working capital, capital expenditures, acquisitions and other general corporate purposes, and limiting our ability to obtain additional financing for these purposes;
	•		subjecting us to the risk of increased sensitivity to interest rate increases on our indebtedness with variable interest rates, including borrowings under senior secured credit facility;
	•		limiting our flexibility in planning for, or reacting to, and increasing our vulnerability to, changes in our business, the industry in which we operate and the general economy; and
	•		placing us at a competitive disadvantage compared to our competitors that have less debt or are less leveraged.

          Any of the above-listed factors could have an adverse effect on our business, financial condition and results of operations and our ability to meet our payment obligations under the Notes and our other debt.

          In addition, on each of October 1, 2011, 2016 and 2021, Notes holders may require us to purchase all or part of the Notes at 100% of the principal amount at which time we may not have the available funds necessary to purchase the Notes.

Our Auction Rate Securities (“ARS”) are currently illiquid and we cancelled our bank credit facility in the U.S.; therefore, we must rely solely upon existing cash reserves, available foreign credit facilities and funds from existing operations to finance future operations.

          We have $320.6 million of par value ARS that became illiquid during the first quarter of 2008 due to the failure of the Dutch auction process. We reached a settlement with UBS AG in the fourth quarter of 2008, which allows us to put the ARS back to UBS AG at any time from June 30, 2010 to July 2, 2012 at par value. As part of the settlement, we entered into a “no net cost loan” that allows us to borrow up to 75% of the market value of the ARS portfolio, as determined by UBS AG. As of December 31, 2008, we have drawn $213 million, which was 75% of the market value upon time of the draw. Although we are not required to repay the loan, we are unable to draw additional funds until the ARS’s market value, as determined by UBS AG, exceeds 75% or until June 30, 2010 when we can put the ARS back to UBS AG.

          On February 6, 2009, we paid in full the outstanding balance of approximately $2.5 million on our revolving credit commitment with Union Bank and terminated the Amended and Restated Credit Agreement that governed the revolving credit commitment. On February 11, 2009, we paid in full the outstanding balance of approximately $1.8 million on our Union Bank term loan facility and terminated the Covenant Agreement that governed that facility, which was scheduled to mature on August 29, 2010.

          As of December 31, 2008, our Asia and Europe subsidiaries have available lines of credit of up to an aggregate of $49.4 million, with several financial institutions. These lines of credit, except for one Taiwanese credit facility, are collateralized by each subsidiary’s premises, are unsecured, uncommitted and, in some instances, must be repaid on demand. Loans under these lines of credit bear interest at LIBOR or similar indices plus a specified margin. At December 31, 2008, $6.1 million was outstanding on these lines of credit, and the average interest rates ranged from 2.0% to 2.8%.

UBS AG may not honor its part of the settlement agreement with us to purchase our entire ARS portfolio at any time beginning from June 30, 2010 to July 2, 2012 at par value.

          ARS are generally long-term debt instruments that are intended to provide liquidity through a Dutch auction process that resets the applicable interest rate at pre-determined calendar intervals. These auctions historically allowed existing investors to rollover their holdings and continue to own their respective securities or liquidate their holdings by selling their securities at par value. Since mid-February 2008, there have been more sellers than buyers at each scheduled

interest rate auction date and parties desiring to sell their securities have been unable to do so.

          On October 29, 2008, we reached an agreement with UBS AG in regard to our ARS portfolio, which gives us the right to sell, which we refer to as the “option to put,” the $320.6 million ARS portfolio back to UBS AG at any time beginning from June 30, 2010 to July 2, 2012 at par value. If UBS AG does not have the financial resources to repurchase our $320.6 million ARS portfolio, we may be required to hold the ARS until maturity, which would negatively impact our liquidity and working capital, and may require us to reclassify and reduce the fair market value of our ARS and our “put” option. The ARS portfolio includes securities with maturity dates ranging from 19 to 39 years.

UBS BANK USA (“UBS Bank”) may demand full or partial repayment of our “no net cost loan” with the UBS Bank at any time at UBS Bank’s sole option and without cause, and UBS Financial Services Inc. may be unable to provide us any alternative financing on substantially same terms and conditions as those of the” no net cost loan.”

          On October 29, 2008, we entered into an ARS settlement with UBS AG to provide liquidity for our $320.6 million ARS portfolio. One of the terms of the ARS settlement is that we may accept an offer of a so-called “no net cost” loan from UBS Bank for up to 75% of the market value, as determined by UBS Bank, of our ARS that we pledged as collateral to UBS Bank. However, the “no net cost loan” is a demand loan, and UBS Bank may demand full or partial repayment of the loan at any time at UBS Bank’s sole option and without cause. Although the ARS settlement arrangement provides that UBS Financial Services Inc. would (i) support us with alternative financing on substantially same terms and conditions as those of the “no net cost loan,” or (ii) have on of the UBS Entities repurchase our ARS portfolio at par, it is possible that UBS Financial Services Inc. would be unable to provide us such alternative financing, particularly under the present and potentially prolonged condition of global economic recession and financial market turmoil. Currently, although we do not expect that UBS Bank would demand full or partial repayment of our outstanding “no net cost loan,” we are unable to provide any assurance that UBS Bank would not do so, and, in case such demand of repayment is made, we are also unable to provide any assurance that UBS Financial Services Inc. would be able to fully satisfy its obligation to provide us with alternative financing on substantially same terms and conditions as those of the “no net cost loan” or that a UBS Entity would repurchase our ARS portfolio at par.

The value of our benefit plan assets and liabilities is based on estimates and assumptions, which may prove inaccurate.

          Certain of the Company’s employees in the United Kingdom, Germany and Taiwan participate in Company sponsored defined benefit plan. The defined benefit plan is closed to new entrants and is frozen with respect to future benefit accruals. The retirement benefit is based on the final average compensation and service of each eligible employee. The Company accounts for these benefit plans in accordance with SFAS No. 158, Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans (an amendment of FASB Statements No. 87, 88, 106 and 132R), which requires the Company to make actuarial assumptions that are used to calculate the earning value of the related assets, where applicable, and liabilities and the amount of expenses to be recorded in the Company’s consolidated financial statements. Assumptions include the expected return on plan assets, discount rates, and mortality rates. While we believe the underlying assumptions, under the projected unit credit method are appropriate, the carrying value of the related assets and liabilities and the actual amount of expenses recorded in the consolidated financial statements could differ materially from the assumptions used.

Due to the recent and ongoing fluctuations in the United Kingdom’s equity markets and bond markets, changes in actuarial assumptions for our defined benefit plan could increase the volatility of the plan’s asset value, require us to increase cash contributions to the plan and have a negative impact on our results of operations and profitability.

          The asset value of the Company’s defined benefit plan (the “plan”) has been volatile in recent months due primarily to wide fluctuations in the United Kingdom’s equity markets and bond markets. The plan assets consist primarily of high quality corporate bonds and stocks traded on the London Stock Exchange and are determined from time to time based on their fair value, requiring the Company to utilize certain actuarial assumptions for the plan’s fair value determination.

          As of December 31, 2008, the benefit obligation of the plan was approximately U.S. $83.3 million and total assets in such plan were approximately U.S. $71.3 million. Therefore, the plan was underfunded by approximately U.S. $12.0 million. The difference between plan obligations and assets, or the funded status of the plan, is a significant factor in determining the net periodic benefit costs of the plan and the ongoing funding requirements of the plan.

          Particularly due to the ongoing fluctuations in the United Kingdom’s equity markets and bond markets, changes in several key actuarial assumptions, including, but not limited to, changes in discount rate, estimated return on the plan and mortality rates, can (i) affect the level of plan funding; (ii) cause volatility in the net periodic pension cost; and (iii) increase

our future funding requirements. In the event that actual results differ from the actuarial assumptions or actuarial assumptions are changed, the funding status of the plan may change. Any deficiency in the funding of the plan could result in additional charges to equity and an increase in future plan expense and cash contribution. A significant increase in our funding requirements could have a negative impact on our results of operations and profitability.

There are risks associated with our acquisition of Zetex.

          The acquisition of Zetex is accompanied by the risks commonly encountered in acquisitions of companies. These risks include, among other things, higher than anticipated acquisition costs and expenses, the difficulty and expense of integrating the operations and personnel of the companies, the difficulty of bringing Zetex’s standards, procedures and controls into conformance with our operations, the ability to coordinate our new products and process development with Zetex, the ability to hire additional management and other critical personnel to better manage Zetex, the ability to increase the scope, geographic diversity and complexity of our operations with the addition of Zetex, difficulties in consolidating facilities and transferring processes and know-how with Zetex, difficulties in reducing costs of Zetex business, prolonged diversion of our management’s attention from the management of our business to matters related to Zetex, the ability to clearly define our present and future strategies with the addition of Zetex and the loss of key employees and customers as a result of changes in management.

          In addition, geographic distances may make the integration of Zetex slower and more challenging. We may ultimately not be successful in overcoming these risks or any other problems encountered in connection with the acquisition of Zetex.

          Our acquisition may cause large one-time expenses as well as create goodwill and other intangible assets that may result in significant asset impairment charges in the future. We have made preliminary estimates and assumptions in order to determine purchase price allocation and estimate the fair value of acquired assets and liabilities of Zetex. If our estimates or assumptions used to value acquired assets and liabilities of Zetex are not accurate, we may be exposed to gains or losses that may be material to our results of operations and profitability.

If we fail to maintain an effective system of internal controls or discover material weaknesses in our internal controls over financial reporting, we may not be able to report our financial results accurately or detect fraud, which could harm our business and the trading price of our Common Stock.

          Effective internal controls are necessary for us to produce reliable financial reports and are important in our effort to prevent financial fraud. We are required to periodically evaluate the effectiveness of the design and operation of our internal controls. These evaluations may result in the conclusion that enhancements, modifications or changes to our internal controls are necessary or desirable. While management evaluates the effectiveness of our internal controls on a regular basis, these controls may not always be effective. There are inherent limitations on the effectiveness of internal controls including collusion, management override, and failure of human judgment. Because of this, control procedures are designed to reduce rather than eliminate business risks. If we fail to maintain an effective system of internal controls or if management or our independent registered public accounting firm were to discover material weaknesses in our internal controls, we may be unable to produce reliable financial reports or prevent fraud which could harm our financial condition and results of operations and result in loss of investor confidence and a decline in our stock price.

Our management certification and auditor attestation regarding the effectiveness of our internal control over financial reporting as of December 31, 2008 excluded the operations of Zetex. If we are not able to integrate Zetex operations into our internal control over financial reporting, our internal control over financial reporting may not be effective.

          Section 404 of the Sarbanes-Oxley Act (“SOX 404”) requires us to furnish a management certification and auditor attestation regarding the effectiveness of our internal control over financial reporting. As a public company, we are required to report, among other things, control deficiencies that constitute a “material weakness” or changes in internal control that materially affect, or are reasonably likely to materially affect, internal control over financial reporting. A “material weakness” is a deficiency, or a combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of the registrant’s annual or interim financial statements will not be prevented or detected on a timely basis.

          Complying with SOX 404 is time consuming and costly. Prior to the acquisition, Zetex was a United Kingdom based, publicly traded company, listed on the London Stock Exchange and was not required to comply with SOX 404. The integration of Zetex operations into our internal control over financial reporting will require additional time and resources from our management and other personnel and may increase our compliance costs. The majority of Zetex operations are in the United Kingdom and in Germany. Such geographic distance between Zetex and our United States’ headquarters may

make the integration process of Zetex slower and more difficult. Therefore, our management certification and auditor attestation regarding the effectiveness of our internal control over financial reporting as of December 31, 2008 excluded the operations of Zetex.

          Failure to comply with SOX 404, including a delay in or failure to successfully integrate Zetex operations into our internal control over financial reporting, or the report by us of a material weakness may cause investors to lose confidence in our consolidated financial statements, and the trading price of our Common Stock may decline. If we fail to remedy any material weakness, our financial statements may be inaccurate, our access to the capital markets may be restricted and the trading price of our Common Stock may decline.

Terrorist attacks, or threats or occurrences of other terrorist activities whether in the United States or internationally may affect the markets in which our Common Stock trades, the markets in which we operate and our profitability.

          Terrorist attacks, or threats or occurrences of other terrorist or related activities, whether in the United States or internationally, may affect the markets in which our Common Stock trades, the markets in which we operate and our profitability. Future terrorist or related activities could affect our domestic and international sales, disrupt our supply chains and impair our ability to produce and deliver our products. Such activities could affect our physical facilities or those of our suppliers or customers. Such terrorist attacks could cause seaports or airports, to or through which we ship, to be shut down, thereby preventing the delivery of raw materials and finished goods to or from our manufacturing facilities in Shanghai, China, Taiwan, Kansas City, Missouri, or Oldham, England, or to our regional sales offices. Due to the broad and uncertain effects that terrorist attacks have had on financial and economic markets generally, we cannot provide any estimate of how these activities might affect our future results.

RISKS RELATED TO OUR INTERNATIONAL OPERATIONS

Our international operations subject us to risks that could adversely affect our operations.

          We expect net sales from foreign markets to continue to represent a significant portion of our total net sales. In addition, the majority of our manufacturing facilities are located overseas in China. In 2006, 2007 and 2008, net sales to customers outside the United States represented 77.8%, 79.7% and 80.2%, respectively, of our net sales. There are risks inherent in doing business internationally, and any or all of the following factors could cause harm to our business:

	•		changes in, or impositions of, legislative or regulatory requirements, including tax laws in the United States and in the countries in which we manufacture or sell our products;
	•		compliance with trade or other laws in a variety of jurisdictions;
	•		trade restrictions, transportation delays, work stoppages, and economic and political instability;
	•		changes in import/export regulations, tariffs and freight rates;
	•		difficulties in collecting receivables and enforcing contracts;
	•		currency exchange rate fluctuations;
	•		restrictions on the transfer of funds from foreign subsidiaries to the United States;
	•		the possibility of international conflict, particularly between or among China and Taiwan and the United States;
	•		legal regulatory, political and cultural differences among the countries in which we do business;
	•		longer customer payment terms; and
	•		changes in U.S. or foreign tax regulations.

We have significant operations and assets in China, Taiwan, Hong Kong and England and, as a result, will be subject to risks inherent in doing business in those jurisdictions, which may adversely affect our financial performance.

          We have a significant portion of our assets in mainland China, Taiwan, Hong Kong and England. Our ability to operate in China, Taiwan, Hong Kong and England may be adversely affected by changes in those jurisdictions’ laws and regulations, including those relating to taxation, import and export tariffs, environmental regulations, land use rights, property and other matters. In addition, our results of operations are subject to the economic and political situations. We believe that our operations are in compliance with all applicable legal and regulatory requirements. However, the central or local governments of these jurisdictions may impose new, stricter regulations or interpretations of existing regulations that would require additional expenditures and efforts on our part to ensure our compliance with such regulations or interpretations.

          Changes in the political environment or government policies in those jurisdictions could result in revisions to laws or regulations or their interpretation and enforcement, increased taxation, restrictions on imports, import duties or currency revaluations. In addition, a significant destabilization of relations between or among China, Taiwan or Hong Kong and the United States could result in restrictions or prohibitions on our operations or the sale of our products or the forfeiture of our assets in these jurisdictions. There can be no certainty as to the application of the laws and regulations of these jurisdictions in particular instances. Enforcement of existing laws or agreements may be sporadic and implementation and interpretation of laws inconsistent. Moreover, there is a high degree of fragmentation among regulatory authorities, resulting in uncertainties as to which authorities have jurisdiction over particular parties or transactions. The possibility of political conflict between these countries or with the United States could have an adverse impact upon our ability to transact business in these jurisdictions and to generate profits.

We could be adversely affected by violations of the United States’ Foreign Corrupt Practices Act and similar worldwide anti-bribery laws.

          The United States’ Foreign Corrupt Practices Act (“FCPA”) and similar anti-bribery laws in other jurisdictions generally prohibit companies and their intermediaries from making improper payments to government officials for the purpose of obtaining or retaining business. Our policies mandate compliance with these anti-bribery laws. We operate in many parts of the world that may have experienced governmental corruption to some degree and, in certain circumstances, strict compliance with anti-bribery laws may conflict with local customs and practices. We train our staff concerning FCPA and related anti-bribery laws. We are in the process of setting up procedures and controls to monitor internal and external compliance. There can be no assurance that our internal controls and procedures always will protect us from reckless or criminal acts committed by our employees or agents. If we are found to be liable for FCPA violations (either due to our own acts or inadvertence, or due to the acts or inadvertence of others), we could suffer from criminal or civil penalties or other sanctions, which could have a material adverse effect on our business.

We are subject to foreign currency risk as a result of our international operations.

          We face exposure to adverse movements in foreign currency exchange rates, primarily Asian currencies, the Euro and the British Pound Sterling. In addition, we sell our products in various currencies and, accordingly, a decline in the value of any such currency against the U.S. dollar, which is our primary functional currency, could create a decrease in our net sales. Our foreign currency risk may change over time as the level of activity in foreign markets grows and could have an adverse impact upon our financial results. These currencies are principally the Chinese Yuan, the Taiwanese dollar, the Japanese Yen, the Euro, the Hong Kong dollar and the British Pound Sterling. The Chinese government has taken action to permit the Yuan to U.S. dollar exchange rate to fluctuate, which may exacerbate our exposure to foreign currency risk and harm our results of operations. We do not usually employ hedging techniques designed to mitigate foreign currency exposures and, therefore, we could experience currency losses as these currencies fluctuate against the U.S. dollar.

We may not continue to receive preferential tax treatment in Asia, thereby increasing our income tax expense and reducing our net income.

          As an incentive for establishing our manufacturing subsidiaries in China, we receive preferential tax treatment. In addition, in conjunction with the acquisition of Anachip, we also receive preferential tax treatment in Taiwan. Governmental changes in foreign tax law may cause us not to be able to continue receiving these preferential tax treatments in the future, which may cause an increase in our income tax expense, thereby reducing our net income.

The distribution of any earnings of our foreign subsidiaries to the United States may be subject to U.S. income taxes, thus reducing our net income.

          With the establishment of our holding companies in 2007, we now intend to permanently reinvest overseas all earnings from foreign subsidiaries. Accordingly, the $3.3 million deferred tax liability was reversed during 2007 and U.S. taxes are no longer being recorded on undistributed foreign earnings.

          As of December 31, 2008, accumulated and undistributed earnings of our subsidiaries in China were approximately $106.4 million, which we considered as a permanent investment.

          As of December 31, 2008, we have undistributed earnings from non-U.S. operations of approximately $144 million. Additional Federal and state income taxes of approximately $41 million would be required should such earnings be repatriated to the U.S. parent.

          We may, in the future, plan to distribute earnings of our foreign subsidiaries to the U.S. We may be required to pay U.S. income taxes on these earnings to the extent we have not previously recorded deferred U.S. taxes on such earnings. Any such taxes would reduce our net income in the period in which these earnings are distributed.

RISKS RELATED TO OUR COMMON STOCK

Variations in our quarterly operating results may cause our stock price to be volatile.

          We have experienced substantial variations in net sales, gross profit margin and operating results from quarter to quarter. We believe that the factors that influence this variability of quarterly results include:

	•		general economic conditions in the countries where we sell our products;
	•		seasonality and variability in the computing and communications market and our other end-markets;
	•		the timing of our and our competitors’ new product introductions;
	•		product obsolescence;
	•		the scheduling, rescheduling and cancellation of large orders by our customers;
	•		the cyclical nature of demand for our customers’ products;
	•		our ability to develop new process technologies and achieve volume production at our fabrication facilities;
	•		changes in manufacturing yields;
	•		changes in gross profit margins;
	•		adverse movements in exchange rates, interest rates or tax rates; and
	•		the availability of adequate supply commitments from our outside suppliers or subcontractors.

          Accordingly, a comparison of our results of operations from period to period is not necessarily meaningful to investors and our results of operations for any period do not necessarily indicate future performance. Variations in our quarterly results may trigger volatile changes in our stock price.

We may enter into future acquisitions and take certain actions in connection with such acquisitions that could affect the price of our Common Stock.

          As part of our growth strategy, we expect to review acquisition prospects that would implement our vertical integration strategy or offer other growth opportunities. While we do not currently have any agreements or commitments in place with respect to any material acquisitions, we are in various stages of preliminary discussions, and we may acquire businesses, products or technologies in the future. In the event of future acquisitions, we could:

	•		use a significant portion of our available cash;
	•		issue equity securities, which would dilute current stockholders’ percentage ownership;
	•		incur substantial debt;
	•		incur or assume contingent liabilities, known or unknown;
	•		incur amortization expenses related to intangibles; and
	•		incur large, immediate accounting write-offs.

          Such actions by us could harm our results from operations and adversely affect the price of our Common Stock.

Our directors, executive officers and significant stockholders hold a substantial portion of our Common Stock, which may lead to conflicts with other stockholders over corporate transactions and other corporate matters.

          Our directors, executive officers and our affiliate, LSC, beneficially own approximately 36.7% of our outstanding Common Stock, including options to purchase shares of our Common Stock that are exercisable within 60 days of December 31, 2008. These stockholders, acting together, will be able to influence significantly all matters requiring stockholder approval, including the election of directors and significant corporate transactions such as mergers or other business combinations. This control may delay, deter or prevent a third party from acquiring or merging with us, which could adversely affect the market price of our Common Stock.

          LSC, our largest stockholder, owns approximately 20.2% (approximately 8.4 million shares) of our Common Stock. Some of our directors and executive officers may have potential conflicts of interest because of their positions with LSC or their ownership of LSC common stock. Some of our directors are LSC directors and officers, and our non-employee Chairman of our Board of Directors is Chairman of the board of LSC. Several of our directors and executive officers own LSC common stock and hold options to purchase LSC common stock. Service on our Board of Directors and as a director or officer of LSC, or ownership of LSC common stock by our directors and executive officers, could create, or appear to create, actual or potential conflicts of interest when directors and officers are faced with decisions that could have different implications for LSC and us. For example, potential conflicts could arise in connection with decisions involving the Common Stock owned by LSC, or under the other agreements we may enter into with LSC. LSC was our largest external supplier of discrete semiconductor products for subsequent sale by us. In 2007 and 2008, approximately 11.3% and 9.6%, respectively, of our net sales were from products manufactured by LSC. In addition to being our largest external supplier of finished products in each of these periods, we sold

silicon wafers to LSC totaling 6.2% and 3.5%, respectively, of our net sales during such periods, making LSC our largest customer.

          We may have difficulty resolving any potential conflicts of interest with LSC, and even if we do, the resolution may be less favorable than if we were dealing with an entirely unrelated third party.

We were formed in 1959, and our early corporate records are incomplete. As a result, we may have difficulty in assessing and defending against claims relating to rights to our Common Stock purporting to arise during periods for which our records are incomplete.

          We were formed in 1959 under the laws of California and reincorporated in Delaware in 1968. We have had several transfer agents over the past 50 years. In addition, our early corporate records, including our stock ledger, are incomplete. As a result, we may have difficulty in assessing and defending against claims relating to rights to our Common Stock purporting to arise during periods for which our records are incomplete.

Conversion of our convertible senior notes will dilute the ownership interest of existing stockholders, including holders who had previously converted their notes.

          To the extent we issue Common Stock upon conversion of the notes, the conversion of some or all of the notes will dilute the ownership interests of existing stockholders, including holders who have received Common Stock upon prior conversion of the notes. Any sales in the public market of the Common Stock issuable upon such conversion could adversely affect prevailing market prices of our Common Stock. In addition, the existence of the notes may encourage short selling by market participants because the conversion of the notes could depress the price of our Common Stock.

The repurchase rights and the increased conversion rate triggered by a make-whole fundamental change could discourage a potential acquirer.

          If a “fundamental change” in accordance with the terms of the senior convertible notes were to occur, the holders of the notes have the right to require us to repurchase the notes. A fundamental change would include a change in control of the Company. In addition, if a make-whole fundamental change were to occur, which may include an acquisition of the Company, the conversion rate for the senior convertible notes will increase. The repurchase rights in our senior convertible notes triggered by a fundamental change and the increased conversion rate triggered by a make-whole fundamental change could discourage a potential acquirer.

Anti-takeover effects of certain provisions of Delaware law and our Certificate of Incorporation and Bylaws.

          Some provisions of Delaware law, our certificate of incorporation and bylaws may be deemed to have an anti-takeover effect and may delay or prevent a tender offer or takeover attempt, including those attempts that might result in a premium over the market price for the shares held by stockholders.

Section 203 of Delaware General Corporation Law

          Section 203 of the Delaware General Corporation Law prohibits transactions between a Delaware corporation and an “interested stockholder,” which is defined as a person who, together with any affiliates or associates, beneficially owns, directly or indirectly, 15.0% or more of the outstanding voting shares of a Delaware corporation. This provision prohibits certain business combinations between an interested stockholder and a Delaware corporation for a period of three years after the date the stockholder becomes an interested stockholder, unless:

(i) either the business combination or the transaction which resulted in the stockholder becoming an interested stockholder is approved by the corporation’s board of directors prior to the date the interested stockholder becomes an interested stockholder;

(ii) the interested stockholder acquired at least 85.0% of the voting stock of the corporation (other than stock held by directors who are also officers or be certain employee stock plans) in the transaction in which the stockholder became an interested stockholder; or

(iii) the business combination is approved by a majority of the board of directors and by the affirmative vote of 66.66% of the outstanding voting stock that is not owned by the interested stockholder.

          For this purpose, business combinations include mergers, consolidations, sales or other dispositions of assets having an aggregate value in excess of 10.0% of the aggregate market value of the consolidated assets or outstanding stock of the

corporation, and certain transactions that would increase the interested stockholder’s proportionate share ownership in the corporation.

Certificate of Incorporation and Bylaw Provisions

          Provisions of our certificate of incorporation and bylaws may have the effect of making it more difficult for a third party to acquire control of our Company. In particular, our certificate of incorporation authorizes our Board of Directors to issue, without further action by the stockholders, up to 1,000,000 shares of preferred stock with rights and preferences, including voting rights, designated from time to time by the Board of Directors. The existence of authorized but unissued shares of preferred stock enables our Board of Directors to render it more difficult or to discourage an attempt to obtain control of us by means of a merger, tender offer, proxy contest or otherwise.

Item 3. Legal Proceedings

          We are currently a party to a legal proceeding described below. While we presently believe that the ultimate outcome of the proceeding will not have a material adverse effect on our financial position, cash flows or overall results of operations, litigation is subject to inherent uncertainties, and unfavorable rulings could occur. An unfavorable ruling could include monetary damages or an injunction prohibiting us from selling one or more products. Were an unfavorable ruling to occur, there exists the possibility of a material adverse impact on our business or results of operations for the period in which the ruling occurs or future periods.

Integrated Discrete Devices, LLC. v. Diodes Incorporated, C.A. No. 08-888 (GMS) (D. Del.)

          On November 25, 2008, Integrated Discrete Devices, LLC (“IDD”) filed a complaint for patent infringement against the Company in the United States District Court for the District of Delaware (the “Court”) under the patent laws of the United States, 35 U.S.C. §§ 100 et seq., alleging that the Company has been and is infringing, actively inducing others to infringe, or contributing to the infringement of IDD’s United States Patent No. 5,825,079 (the “‘079 patent”) by making, using, selling, offering to sell, or importing diode products embodying the patented invention, including, but not limited to, its Super Barrier Rectifier (or SBR ^®) diodes. IDD’s complaint further alleges that the Company has been and is infringing the ‘079 patent with knowledge of the patent, and thus the Company’s infringement is willful and that the Company will continue to infringe the ‘079 patent unless and until it is enjoined by the Court. IDD’s complaint further alleges that the Company has caused and will continue to cause IDD irreparable injury and damage by infringing the ‘079 patent and that IDD will suffer further irreparable injury unless and until the Company is enjoined from infringing the ‘079 patent. IDD’s complaint seeks that the Court enter infringement judgment against the Company on the ‘079 patent and enter an order permanently enjoining the Company from infringing the ‘079 patent. IDD also seeks unspecified damages together with pre-judgment and post-judgment interest and costs, treble damages, additional damage, an injunction, attorneys’ fees, expenses and costs as well as other relief.

          On December 19, 2008, both parties stipulated to a one-month filing time extension for the Company to consider and respond to the allegations raised in IDD’s complaint. The Court approved the filing time extension stipulation by both parties on the same day.

          On January 23, 2009, the Company filed an answer and counterclaims to IDD’s complaint. The Company believes that it has meritorious defenses against IDD’s claims, and intends to defend the lawsuit vigorously.

          From time to time, the Company is involved in various routine legal proceedings incidental to the conduct of its business. Management does not believe that any of these legal proceedings will have a material adverse impact on the business, financial condition or results of operations of the Company.

Item 4. Submission of Matters to a Vote of Security Holders

          No matter was submitted by us to a vote of security holders during the fourth quarter of 2008.

PART II

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

          On February 23, 2009, the closing sales price of our Common Stock as reported by NasdaqGS was $6.77, and there were approximately 500 holders of record of our Common Stock.

          We have never declared or paid cash dividends on our Common Stock, and currently do not intend to pay dividends in the foreseeable future as we intend to retain any earnings for use in our business. The payment of dividends is within the discretion of our Board of Directors, and will depend upon, among other things, our earnings, financial condition, capital requirements, and general business conditions. There have been no stock repurchases in our history.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

          The following section discusses managements view of the financial condition, results of operations and cash flows of Diodes Incorporated and its subsidiaries (collectively, “the Company,” “our Company,” “we,” “our,” “ours,” or “us”) and should be read together with the consolidated financial statements and the notes to consolidated financial statements included elsewhere in this Form 10-K.

          The following discussion contains forward-looking statements and information relating to our Company. We generally identify forward-looking statements by the use of terminology such as “may,” “will,” “could,” “should,” “potential,” “continue,” “expect,” “intend,” “plan,” “estimate,” “anticipate,” “believe,” “project,” or similar phrases or the negatives of such terms.

Given these risks and uncertainties, prospective investors are cautioned not to place undue reliance on such forward-looking statements. Forward-looking statements do not guarantee future performance and should not be considered as statements of fact.

          You should not unduly rely on these forward-looking statements, which speak only as of the date of this Annual Report on Form 10-K.

Highlights For the Year Ended December 31, 2008

	•		We completed the acquisition of Zetex plc (“Zetex”) in June;
	•		Revenue for 2008 increased 8% over 2007 to $432.8 million, including seven months of Zetex revenues;
	•		Gross profit for 2008 increased 2% or $2.1 million over 2007 to $132.5 million;
	•		In connection with the acquisition of Zetex, we entered into a margin loan for $165 million secured by our auction rate securities (“ARS”) portfolio, which was replaced on November 4, 2008 with a “no net cost loan” from UBS BANK USA (“UBS Bank”);
	•		On October 29, 2008, we entered into a settlement agreement with UBS AG and its affiliates (“UBS AG”) that will allow us to sell our ARS portfolio to UBS AG at par value at any time during the period of June 30, 2010 through July 2, 2012; and
	•		During the fourth quarter of 2008, we repurchased $46.5 million of our $230 million 2.25% Convertible Senior Notes due 2026 for approximately $23.2 million in cash resulting in a $22.8 million pre-tax gain.

Business Outlook

          For 2009 we expect to see a further slowdown in global economic activity and a decrease in global demand for our products, in particular in the consumer, computer and automotive markets. The success of our business depends, among other factors, on the strength of the global economy and the stability of the financial markets, which in term affect our customers’ demand for our products, the ability of our customers to meet their payment obligations, the likelihood of customers canceling or deferring existing orders and end-user consumers’ demand for items containing our products in the end-markets we serve. We believe the long-term outlook for our business remains generally favorable despite the recent volatility in the equity and credit markets as we continue to execute on the strategy that has proven successful for us over the years. Although the economy creates a more challenging environment for all businesses, we believe that over the long-term we are well positioned for future growth. We are confident that our acquisition of Zetex will continue to add significant value to our business as we further capitalize on the cross-selling opportunities and diversification benefits that the transaction offers our Company. See “Risk Factors — Global economic weakness and the current financial market uncertainty has had, and is expected to continue to have through at least 2009, a material adverse effect on our business.” in Part I, Item 1A of this Annual Report.

Cost Reduction Initiative

          Looking forward, we expect the weakness and uncertainty in the economy to continue into the coming quarters, and therefore we have taken, or intend to take, the following steps to optimize our cost structure:

	•		Shut down of Zetex 4 inch wafer fabrication line in Oldham, England;
	•		Consolidate our wafer output lines;

	•		Currently, our Shanghai facilities are under-loaded, therefore, we are transferring the production of products acquired in our purchase of Zetex into our Shanghai packaging facilities sooner than originally planned and thereby reducing our dependence on subcontractors and maximizing the utilization of our internal capacity;
	•		As part of our manufacturing strategy, we plan to reduce inventory and will continue to evaluate our raw material costs in order to reduce our gold consumption while protecting and maintaining product performance;
	•		Reduce capital expenditures from our previous 10 to 12 percent model to less than 2% until such time that the market recovers and additional manufacturing capacity is needed;
	•		Restructure our product development organization and consolidate the acquired Zetex design teams;
	•		Headcount reductions across the entire organization, primarily at our wafer fabrication facilities in Kansas City and Oldham;
	•		Temporary site shut-downs and mandatory time off; and
	•		Implement a hiring and compensation freeze, and from an overall expense perspective, implement strict controls over discretionary spending in order to conserve cash.

Overview

          We are currently experiencing a global decrease in demand for our products and expect the decrease in demand to continue until economic conditions improve. Even as we are experiencing a decrease in product demand, our strategy is to continue to enhance our position as a leading global manufacturer and supplier of high-quality semiconductor products, and to continue to add other product lines, such as power management products, using our packaging technology capability.

          As described in “Business — Our Strategy” in Part I, Item 1 of this Annual Report, the principal elements of our strategy include the following:

	•		Continue to rapidly introduce innovative discrete and analog semiconductor products;
	•		Expand our available market opportunities;
	•		Maintain intense customer focus;
	•		Enhance cost competitiveness; and
	•		Pursue selective strategic acquisitions.

          In implementing this strategy, the following factors have affected, and, we believe, will continue to affect, our results of operations:

	•		The current economic downturn has resulted in a decrease in demand for our products, which we expect to continue until economic conditions improve. As a result, for 2009, we do not expect to sustain our historical growth rate. In addition, our net sales for 2008 reflect the impact of the overall weakening economy, in particular on key targeted end-equipment in the consumer and computing markets, as well as our foundry and subcontracting business, which showed greater weakness than our core revenue drivers.
	•		We have experienced substantial pressure from our customers and competitors to reduce the selling price of our products. See “Risk Factors — We are and will continue to be under continuous pressure from our customers and competitors to reduce the price of our products, which could adversely affect our growth and profit margins” in Part I, Item 1A of this Annual Report. Although we do not expect to sustain our historical growth rate in 2009, we expect any future improvements in net income to result primarily from increases in sales volume and improvements in product mix, which will continue to improve the average selling prices of our products.
	•		Sales of new products (products that have been sold for three years or less) for the years ended December 31, 2006, 2007 and 2008 amounted to 28.2%, 35.1% and 26.9% of total sales, respectively, including the contribution of recent acquisitions. New products generally have gross profit margins that are higher than the margins of our standard products. We believe the sales from new products is an important measure given the short life cycles of some of our products. See “Risk Factors — Our business may be adversely affected by obsolete inventories as a result of changes in demand for our products and change in life cycles of our products” in Part I, Item 1A of this Annual Report for additional information about product life cycles.
	•		Our gross profit margin was 30.6% in 2008, compared to 32.5% in 2007 and 33.2% in 2006. Our gross profit margin decrease in 2008 was affected by lower capacity utilization at our manufacturing operations primarily due to current economic conditions along with the one time non-cash expense of $5.4 million incurred during the third quarter of 2008 for the increase in inventory for reasonable profit allowance in accordance with Financial Accounting Standards Board (“FASB”) Statement of Financial Accounting Standards (“SFAS”) No. 141, Business Combinations and depreciation expense of fixed assets in connection with the Zetex acquisition. In 2007, we completed the move of our analog product from Taiwan to our Shanghai manufacturing facilities to increase the gross margin on this product line. Future gross profit margins will depend primarily on our utilization, product mix, cost savings, and the demand

for our products. We expect gross profit margins to continue to remain under significant pressure until economic conditions improve.

	•		For 2008, the percentage of our net sales derived from our Asian subsidiaries was 74.2%, compared to 75.4% in 2007 and 71.9% in 2006. We expect our net sales to the Asian market to increase as a percentage of our total net sales as a result of our customers’ continuing to shift their manufacturing of electronic products to Asia.
	•		As a result of the Zetex acquisition we have added significant revenue in Europe. As such, Europe accounted for approximately 15.6% of our revenues in 2008.
	•		As of December 31, 2008, we had invested approximately $197.3 million in our manufacturing facilities in China. During 2008, we invested approximately $30.0 million in these manufacturing facilities, and we expect to continue to invest in our manufacturing facilities, although the amount to be invested will depend on product demand and new product developments.
	•		For 2008, our capital expenditures were approximately 12.3% of annual revenue. Given the current economic conditions and our efforts to reduce costs, we expect capital expenditures to be less than 2% of revenue for 2009 or until economic conditions improve and additional manufacturing capacity is needed.
	•		We increased our investment in research and development from $13.5 million in 2007 to $22.5 million in 2008, primarily as a result of the Zetex acquisition. In 2008, research and development expenses were approximately 5.2% of net sales. Although research and development increased in 2008, we expect the investment to decrease for 2009 as we are planning to restructure our product development organization and consolidate our design teams and to reduce costs, but to increase as a percentage of net sales due to the lower expected net sales.

Convertible Senior Notes

          On October 12, 2006, we issued and sold convertible senior notes with an aggregate principal amount of $230 million due 2026 (“Notes”), which pay 2.25% interest per annum on the principal amount of the Notes, payable semi-annually in arrears on April 1 and October 1 of each year, beginning on April 1, 2007. The Notes will be convertible into cash or, at our option, cash and shares of our Common Stock based on an initial conversion rate, subject to adjustment, of 25.6419 shares (split adjusted) per $1,000 principal amount of Notes (which represents an initial conversion price of $39.00 per share, split adjusted), in certain circumstances. In addition, following a “make-whole fundamental change” that occurs prior to October 1, 2011, we will, at our option, increase the conversion rate for a holder who elects to convert its Notes in connection with such “make-whole fundamental change,” in certain circumstances.

          During the fourth quarter of 2008 and the first quarter of 2009, we repurchased $46.5 million and $9.6 million principle amount of the Notes for approximately $23.2 million and $6.6 million in cash, respectively. Beginning January 1, 2009, we will adopt FASB Staff Position (“FSP”) APB 14-1, Accounting for Convertible Debt Instruments That May Be Settled in Cash upon Conversion (Including Partial Cash Settlement), that will change how we account for our Notes and will significantly increase our non-cash interest expense. See “Recently Issued Accounting Pronouncements” below for additional information about FSP APB 14-1 and Note 10 of “Notes to Consolidated Financial Statements” of this Annual Report for addition information the Notes and the repurchase.

Recent Acquisitions

          On November 3, 2006, we completed the purchase of the assets of APD Semiconductor Inc., a privately held U.S.-based fabless semiconductor company. APD’s main product focus is its patented and trademarked SBR^® (super barrier rectifier) technology. The purchase price of the acquisition was $8.4 million in addition to a potential earn-out provision with respect to pre-defined covered products. The APD acquisition further strengthens our technology leadership in the standard semiconductor market and expand our product capabilities across important segments of our end-markets.

          On June 9, 2008, the Company completed the acquisition of all the outstanding ordinary capital stock of Zetex, a company incorporated under the laws of England and Wales. The Zetex shareholders received 85.45 pence in cash per Zetex ordinary share, valuing the fully diluted share capital of Zetex at approximately U.S.$176.3 million (based on a USD:GBP exchange rate of 1.9778), excluding acquisition costs, fees and expenses. In addition, in order to finance the acquisition, the Company entered into a loan agreement for $165 million that was later replaced with a “no net cost loan.” See “Debt instruments” below for additional information about the “no net cost loan.” We believe the acquisition will strengthen and broaden the Company’s product offerings, including entry into the LED lighting and automotive markets and expand the Company’s geographical footprint in the European markets.

          See Note 2 of “Notes to Consolidated Financial Statements” and “Risk Factors — Part of our growth strategy involves identifying and acquiring companies with complementary product lines or customers. We may be unable to identify suitable acquisition candidates or consummate desired acquisitions and, if we do make any acquisitions, we may be unable to successfully integrate any acquired companies with our operations” in Part I, Item 1A of this Annual Report for additional information about our recent acquisitions.

Description of Sales and Expenses

          Net sales

          The principal factors that have affected or could affect our net sales from period to period are:

	•		The condition of the economy in general and of the semiconductor industry in particular, in which we are currently experiencing a global decrease in demand for our products,
	•		Our customers’ adjustments in their order levels,
	•		Changes in our pricing policies or the pricing policies of our competitors or suppliers,
	•		The termination of key supplier relationships,
	•		The rate of introduction to, and acceptance of new products by, our customers,
	•		Our ability to compete effectively with our current and future competitors,
	•		Our ability to enter into and renew key corporate and strategic relationships with our customers, vendors and strategic alliances,
	•		Changes in foreign currency exchange rates,
	•		A major disruption of our information technology infrastructure, and
	•		Unforeseen catastrophic events, such as armed conflict, terrorism, fires, typhoons and earthquakes.

          Cost of goods sold

          Cost of goods sold includes manufacturing costs for our semiconductors and our wafers. These costs include raw materials used in our manufacturing processes as well as the labor costs and overhead expenses. Cost of goods sold is also impacted by yield improvements, capacity utilization and manufacturing efficiencies. We are currently experiencing lower than normal utilization due to the current economic conditions. In addition, cost of goods sold includes the cost of products that we purchase from other manufacturers and sell to our customers. Cost of goods sold is also affected by inventory obsolescence if our inventory management is not efficient.

          Selling, general and administrative expenses

          Selling, general and administrative expenses relate primarily to compensation and associated expenses for personnel in general management, sales and marketing, information technology, engineering, human resources, procurement, planning and finance, and sales commissions, as well as outside legal, accounting and consulting expenses, and other operating expenses. Given the current economic conditions, we expect our selling, general and administrative expenses to decrease in absolute dollars for reasons described above in “Cost Reduction Initiative” and expect the decrease to continue until conditions improve.

          Research and development expenses

          Research and development expenses consist of compensation and associated costs of employees engaged in research and development projects, as well as materials and equipment used for these projects. Research and development expenses are primarily associated with our wafer facilities in Kansas City, Missouri and Oldham, England and our facilities in China and Taiwan, as well as with our engineers in the U.S. All research and development expenses are expensed as incurred. We expect our research and development expenses to decrease in absolute dollars given the current economic conditions and our plans to reduce expenses for reasons described above in “Cost Reduction Initiative” until economic conditions improve.

          Amortization of acquisition related intangible assets

          Amortization of acquisition related intangible assets consist of amortization of acquisition-related intangible assets, such as developed technologies and customer relationships.

          In-process research and development

          In-process research and development (“IPR&D”) expenses consist of immediately expensed IPR&D, which had not yet reached technological feasibility and had no alternative future use as of the acquisition date in accordance with SFAS No. 141.

          Restructuring charge

          Restructuring charge consists of charges to reduce our cost structure to enhance operating effectiveness and improve profitability in accordance with SFAS No. 146, Accounting for Costs Associated with Exit or Disposal Activities.

          Interest income / expense

          Interest income consists of interest earned on our cash and investment balances. Interest expense consists of interest payable on our outstanding credit facilities and other debt instruments including the convertible senior notes. We expect our non-cash interest expense to increase significantly in 2009 when we adopt FSP APB 14-1. See “Recently Issued Accounting Pronouncements” below for further details on FSP APB 14-1.

          Income tax provision

          Our global presence requires us to pay income taxes in a number of jurisdictions. In general, earnings in the U.S. and Taiwan are currently subject to tax rates of 39.0% and 25.0%, respectively. In addition, Taiwan earnings are subject to an additional 10% retained earnings tax should the Taiwan earnings not be distributed. As an incentive for the formation of Anachip Corp., its earnings are subject to a five-year tax holiday (subject to certain qualifications of Taiwanese tax law). Earnings in Hong Kong are subject to a 16.5% tax for local sales or local source sales; all other Hong Kong sales are not subject to foreign income taxes. Earnings in Taiwan and Hong Kong are also subject to U.S. taxes with respect to those earnings that are derived from product manufactured by our China subsidiaries and sold to customers outside of Taiwan and Hong Kong, respectively. The U.S. tax rate on this Subpart F income is computed as the difference between the foreign effective tax rates and the U.S. tax rate. In accordance with U.S. tax law, we receive credit against our U.S. tax liability for income taxes paid by our foreign subsidiaries.

          In addition, the earnings of Shanghai Kai Hong Technology Co., Ltd., which is located in the Songjiang Export Zone of Shanghai, China, were subject to a 12.5% tax rate. The earnings of Shanghai Kai Hong Electronic Co., Ltd. became subject to the standard local government tax rate of 25% for 2008.

          On June 9, 2008, the Company completed the acquisition of all the outstanding ordinary capital stock of Zetex. Earnings in the United Kingdom are currently subject to a tax rate of 28% and its earnings in Hong Kong are subject to a 16.5% tax rate. In addition, earnings in Germany are subject to a 30% tax rate.

          See Note 15 of “Notes to Consolidated Financial Statements” for additional information regarding income taxes.

Results of Operations

          The following table sets forth, for the periods indicated, the percentage that certain items in the statement of income bear to net sales and the percentage dollar increase (decrease) of such items from period to period. All per share amounts have been adjusted to reflect the three-for-two stock splits in December 2005 and July 2007.

          The following discussion explains in greater detail our consolidated operating results and financial condition. This discussion should be read in conjunction with the consolidated financial statements and notes thereto appearing elsewhere in this Annual Report (in thousands).

Year 2008 Compared to Year 2007

		2007				2008
Net sales			$401,159				$432,785

          Net sales for 2008 increased $31.6 million to $432.8 million from $401.2 million for 2007. The 7.9% increase was due primarily to a 2.2% increase in units sold and a 5.6% increase in average selling prices (“ASP”). The revenue increase was attributable to sales increases in all industry segments mainly due to the Zetex acquisition, partially offset by an overall weakening of global demand due to the global economic downturn, as well as our foundry and subcontracting businesses, which showed greater weakness than our core revenue drivers. Significant price pressure and an unfavorable commodity-based product mix also negatively affected sales in 2008.

          The following table sets forth the geographic breakdown of our net sales for the periods indicated based on the country to which the product is billed:

		Net sales for the year								Percentage of
		ended December 31								net sales
		2007				2008				2007				2008
China		$	156,183			$	130,045				38.9	%			30.0	%
Taiwan			102,562				118,577				25.6	%			27.4	%
United States			81,408				85,906				20.3	%			19.8	%
Korea			17,563				21,901				4.4	%			5.1	%
Germany			5,111				17,021				1.3	%			3.9	%
Singapore			9,854				14,852				2.5	%			3.4	%
England			7,710				12,821				1.8	%			3.1	%
All Others			20,768				31,662				5.2	%			7.3	%
Total		$	401,159			$	432,785				100	%			100	%

		2007				2008
Cost of goods sold		$	270,780			$	300,257
Gross profit		$	130,379			$	132,528
Gross profit margin			32.5%				30.6%

          Cost of goods sold increased $29.5 million, or 10.9%, for 2008 compared to $270.8 million for 2007. As a percent of sales, cost of goods sold increased from 67.5% for 2007 to 69.4% for 2008. Our average unit cost (“AUP”) for discrete devices decreased approximately 1.8% from 2007, AUPs for analog products decreased approximately 11.8%, and AUPs for wafer products increased approximately 11.8%. The increase in cost of goods sold and the percentage of sales increase were negatively affected by the one time non-cash expense of $5.4 million incurred during the third quarter of 2008 for the increase of inventory for reasonable profit allowance and depreciation expense related to fixed assets in connection with the Zetex acquisition along with lower capacity utilization in our manufacturing operations due primarily to market conditions. As per SFAS 123R, included in cost of goods sold for 2007 and 2008 were $0.3 million and $0.1 million, respectively, of non-cash, share-based compensation expenses associated with our manufacturing facilities.

          Gross profit for 2008 increased 14.5% to $132.5 million from $130.4 million for 2007. Gross profit margin as a percentage of net sales was 30.6% for 2008, compared to 32.5% for 2007. The decreased gross margin was primarily due to the increase of inventory for reasonable profit allowance and depreciation expense of fixed assets in connection with the Zetex acquisition and lower capacity utilization in our manufacturing operations.

		2007				2008
Selling, general and administrative (“SG&A”)		$	55,127			$	68,373

          SG&A for 2008 increased approximately $13.2 million, or 24.0%, to $68.4 million, compared to $55.1 million for 2007, due primarily to additional SG&A expenses related to the Zetex operations. The following expense categories increased, mainly due to additional Zetex SG&A expenses: (i) $5.0 million increase in wages and related benefits, including

share-based compensation, (ii) $3.6 million increase in facility expense, depreciation, supplies and other operating expenses, (iii) $3.6 million increase in communication, professional expense and travel expense, and (iv) $1.3 million increase in marketing and selling expense. SG&A, as a percentage of net sales, was 15.8% in 2008, compared to 13.7% in 2007. As per SFAS No. 123R, included in SG&A for 2007 and 2008 were $4.8 million and $3.6 million, respectively, of non-cash, share-based compensation expenses.

		2007				2008
Research and development (“R&D”)			$12,955				$21,882

          R&D for 2008 increased $8.9 million to $21.9 million, or 5.1% of net sales, from $13.0 million, or 3.2% of net sales, for 2007. The increase was due primarily to additional R&D expenses related to the Zetex operations. The following expense categories increased, mainly due to additional Zetex R&D expenses: (i) $5.3 million increase in wages and related benefits and (ii) $3.7 million increase in operating expenses, depreciation, building maintenance and operating expense. As per SFAS No. 123R, included in R&D for 2007 and 2008 were $0.5 million and $0.3 million, respectively, of non-cash, share-based compensation expenses.

		2007				2008
Amortization of acquisition-related intangible assets			$836				$3,706

          Amortization of acquisition related intangibles for 2008 increased $2.9 million to $3.7 million from $0.8 million for 2007. The increase was due primarily to approximately $2.6 million of non-cash amortization expense associated with the preliminary identification of intangible assets in connection with the acquisition of Zetex. The 2008 charge related to seven months of amortization expense and we estimate this charge to be approximately $1.3 million per quarter for 2009 based on preliminary projections.

		2007				2008
In-process research and development (“IPR&D”)			$—				$7,865

          During the third quarter of fiscal 2008, per SFAS No. 141, we recorded an approximately $7.9 million one-time, non-cash expense associated with the preliminary identification of acquired intangible IPR&D in connection with the acquisition of Zetex, which had not yet reached technological feasibility and had no alternative future use as of the Zetex acquisition date.

		2007				2008
Restructuring charge			$1,061				$4,089

          In the years ended December 31, 2007 and 2008, we recorded approximately $1.1 million and $4.1 million in restructuring charges, respectively. We have recorded various restructuring charges to reduce our cost structure to enhance operating effectiveness and improve future profitability. These restructuring activities impacted several functional areas of our operations in different locations and were undertaken to meet specific business objectives in light of the facts and circumstances at the time of each restructuring event. For 2008, these charges included costs to reduce the headcount in our UK operations along with additional headcount reductions in our worldwide workforce. For 2007, these charges include costs related to the consolidation of our analog wafer probe and final test operations from Hsinchu, Taiwan to our manufacturing facilities in Shanghai, China, which primarily consisted of termination and severance costs, and impairment of fixed assets.

		2007				2008
Interest income			$18,117				$11,991

          Interest income for 2008 was $12.0 million, compared to $18.1 million for 2007, due primarily to a decrease in interest income earned on our ARS. Interest income for 2008 on our ARS has been impacted by the continued turmoil in the credit markets.

		2007				2008
Interest expense		$	6,831			$	9,348

          Interest expense for 2008 was $9.3 million, compared to $6.8 million for 2007. The $2.5 million increase is due primarily to interest expense related to the $165 million loan used to finance the June 2008 Zetex acquisition. Interest expense related to the 2.25% convertible senior notes was approximately $5.2 million in both 2008 and 2007. Beginning January 1, 2009, we are required to adopt FSP APB 14-1, which will require us to separately account for a liability and equity component of the convertible senior notes. The liability portion of the notes will reflect an estimated 8.5% non-convertible borrowing rate. We therefore expect to record an additional pre-tax, non-cash interest expense of approximately $8 to 9 million for 2009.

		2007				2008
Other income (expense)		$	(225	)		$	16,594

          Other income for 2008 was $16.6 million, compared to other expense of $0.2 million for 2007. The $16.8 million increase was due primarily to a $22.8 gain from extinguishments of debt (in the fourth quarter of 2008, we repurchased $46.5 million of our $230 million 2.25% Convertible Senior Notes for approximately $23.2 million in cash, which reduces our convertible debt to $183.5 million) and $0.9 million foreign currency transaction gains due primarily to favorable Taiwan currency and China currency exchange rate changes during the year, offset by approximately $1.5 million of loss from forward contract hedging related to hedging the Zetex acquisition purchase price, and $5.4 million foreign currency transaction losses due primarily to strengthening of the U.S. dollar versus the British Pound negatively affecting foreign currency hedges entered into by Zetex prior to our acquisition.

		2007				2008
Income tax provision		$	9,428			$	4,585

          We recognized income tax expense of $4.6 million for 2008, resulting in an effective tax rate of 10.0%, as compared to 13.2% for 2007. Our lower effective tax rate compared with the same period last year was the result of income tax refunds in China and the favorable settlement of income tax audits in Taiwan, partially offset by the purchase accounting adjustments from the Zetex acquisition and the repatriation of earnings from our Hong Kong subsidiary. For 2009, we anticipate our full-year effective tax rate to be in the mid-teen range as we continue to take advantage of available strategies to optimize our tax rate across the jurisdictions in which we operate.

		2007				2008
Minority interest in consolidated subsidiaries		$	2,376			$	2,290

          Minority interest in consolidated subsidiaries primarily represented the minority investor’s share of the earnings of our China and Taiwan subsidiaries for the year. The joint venture investments were eliminated in the consolidations of our financial statements, and the activities of our China and Taiwan subsidiaries were included therein. As of December 31, 2007 and 2008, we had 95% controlling interests in Shanghai Kai Hong Electronic Co., Ltd. and Shanghai Kai Hong Technology Co., Ltd., and a 99.8% controlling interest in Anachip Corp.

		2007				2008
Net income		$	59,657			$	38,975

          Net income decreased 34.7% to $39.0 million (or $0.96 basic earnings per share and $0.91 diluted earnings per share) for 2008, compared to $59.7 million (or $1.51 basic earnings per share and $1.41 diluted earnings per share) for 2007, due primarily to increasing pressure on ASP and lower gross profit margin, deteriorating global economy and approximately $14.7 million in purchase price adjustments related to the Zetex acquisition.

Year 2007 Compared to Year 2006

		2006				2007
Net sales		$	343,308			$	401,159

          Net sales for 2007 increased $57.9 million to $401.2 million from $343.3 million for 2006. The 16.9% increase was due primarily to a 25.4% increase in units sold, offset by a 6.8% decrease in ASP. The decrease in ASP was due to the price pressure on our product lines. The following table sets forth the geographic breakdown of our net sales for the periods indicated based on the country to which the product is shipped:

		Net sales for the year								Percentage of
		ended December 31								net sales
		2006				2007				2006				2007
China		$	118,303			$	156,183				34.5	%			38.9	%
Taiwan			96,401				102,562				28.1	%			25.6	%
United States			76,357				81,408				22.2	%			20.3	%
All Others			52,247				61,006				15.2	%			15.2	%
Total		$	343,308			$	401,159				100	%			100	%

		2006				2007
Cost of goods sold		$	229,416			$	270,780
Gross profit		$	113,892			$	130,379
Gross profit margin			33.2	%			32.5	%

          Cost of goods sold increased $41.4 million, or 18.0%, for 2007 compared to $229.4 million for 2006. As a percent of sales, cost of goods sold increased from 66.8% for 2006 to 67.5% for 2007. Our AUP for discrete devices decreased approximately 2.4% from 2006, AUPs for analog products decreased approximately 12.8%, and AUPs for wafer products decreased approximately 1.6%. As per SFAS No. 123R, included in cost of goods sold for 2006 and 2007 were $0.5 million and $0.3 million, respectively, of non-cash, stock option compensation expenses related to our manufacturing facilities.

          Gross profit for 2007 increased 14.5% to $130.4 million from $113.9 million for 2006. Gross margin as a percentage of net sales was 32.5% for 2007, compared to 33.2% for 2006. The decreased gross margin was primarily due to product mix changes.

		2006				2007
SG&A		$	47,817			$	55,127

          SG&A expenses for 2007 increased approximately $7.3 million, or 15.3%, to $55.1 million, compared to $47.8 million for 2006, due primarily to (i) an approximately $1.6 million increase associated with non-cash, share-based compensation expense related to options and share grants, (ii) $4.2 million higher sales commissions, wages and marketing expenses associated with the increased marketing and operating activities, and (iii) $0.8 million increase in audit expenses associated with Sarbanes-Oxley Act compliance. SG&A, as a percentage of net sales, was 13.7% in 2007, compared to 13.9% in 2006.

		2006				2007
R&D		$	8,237			$	12,955

          R&D expenses for 2007 increased $4.7 million to $13.0 million, or 3.2% of net sales, from $8.2 million, or 2.4% of net sales, for 2006. R&D expenses are primarily related to new product development at the silicon wafer level and at the packaging level.

		2006				2007
Restructuring charge		$	—			$	1,061

          For 2007, we recorded approximately $1.1 million in restructuring charges related to the consolidated of our analog wafer probe and final test operations from Hsinchu, Taiwan to our manufacturing facilities in Shanghai, China, which primarily consisted of termination and severance costs and impairment of fixed assets.

		2006				2007
Interest income		$	6,699			$	18,117

          Interest income for 2007 was $18.1 million, compared to $6.7 million for 2006, due primarily to interest income earned on short-term investment securities purchased with the proceeds from the $230 million convertible bonds.

		2006				2007
Interest expense		$	1,884			$	6,831

          Interest expense for 2007 was $6.8 million, compared to $1.8 million for 2006, due primarily to $4.1 million increase in interest expense related to the 2.25% convertible bonds ($5.2 million in 2007, compared to $1.1 million in 2006), and to a lesser extent, $1.1 million increase in amortization related convertible bonds issuance costs relating to the full year 2007 amortization expense.

		2006				2007
Other expense		$	(1,212	)		$	(225	)

          Other expense for 2007 was $0.2 million, compared to $1.2 million for 2006. The $1.0 million decrease in other expense was due primarily to $1.1 million one time adjustment for currency exchange losses in the third quarter of 2006 and $0.1 million decrease in currency exchange loss in 2007.

		2006				2007
Income tax provision		$	11,689			$	9,428

          We recognized income tax expense of $9.4 million for 2007, resulting in an effective tax rate of 13.2%, as compared to 19.1% for 2006. Our lower effective tax rate compared with the same period last year was the result of lower income in the U.S and higher income in low-taxed foreign jurisdictions, as well as a decrease in the amount of estimated repatriation of earnings of our foreign subsidiaries, partially offset by the increased income tax rate at one of our China subsidiaries (Shanghai Kai Hong Technology Co., Ltd. is subject to a range of 7.5% to 12.5% preferential tax rate from 2007 through 2009, compared to a 0% tax rate in 2006).

		2006				2007
Minority interest in consolidated subsidiaries		$	1,289			$	2,376

          Minority interest in consolidated subsidiaries primarily represented the minority investor’s share of the earnings of our China and Taiwan subsidiaries for the year. The joint venture investments were eliminated in the consolidations of our financial statements, and the activities of our China and Taiwan subsidiaries were included therein. As of December 31, 2006 and 2007, we had 95% controlling interests in Shanghai Kai Hong Electronic Co., Ltd. and Shanghai Kai Hong Technology Co., Ltd., and a 99.8% controlling interest in Anachip Corp.

		2006				2007
Net income		$	48,143			$	59,657

          Net income increased 23.9% to $59.7 million (or $1.51 basic earnings per share and $1.41 diluted earnings per share) for 2007, compared to $48.1 million (or $1.25 basic earnings per share and $1.16 diluted earnings per share) for 2006, due primarily to increased revenue, higher net interest income from short-term investments and a lower effective tax rate.

Financial Condition

          Liquidity and Capital Resources

          Due to the weakness of the global economy and recent changes to our organizational structure to maximize efficiencies and reduce costs, we have engaged in an in-depth review of our cash requirements, current cash balances, future cash availability and our borrowing costs. As part of this review, we have sought to reduce our interest expense by taking the following steps:

	•		In January 2009, we borrowed an additional $1.7 million against our “no net cost loan” facility with UBS BANK USA, bringing the total outstanding balance to $213 million. See below for additional information about our “no net cost loan” facility.
	•		Due to the lower interest rate earned on cash balances by one of our foreign subsidiaries and higher interest rate charged to borrow cash in the U.S., we transferred approximately $5 million from that foreign subsidiary into our U.S. bank account during the first quarter of 2009.
	•		In February 2009, we paid in full the outstanding balance on our revolving credit commitment and our term loan facility and terminated our Amended and Restated Credit Agreement and Covenant Agreement with Union Bank. We have no current plans to replace these credit facilities; however, should future business needs arise and the credit markets permit, we may seek to obtain additional credit facilities.

          Our primary sources of liquidity are cash, funds from operations and borrowings under our credit facilities. Our primary liquidity requirements have been to meet our inventory and capital expenditure needs. For 2006, 2007 and 2008, our working capital was $395.4 million, $451.8 million, and $208.4 million, respectively. Our working capital decreased in 2008 mainly due to the re-classification of our ARS portfolio from current assets to long-term assets as a result of the their lack of liquidity. We expect cash generated by our U.S. and international operations, together with existing cash, cash equivalents, and available credit facilities to be sufficient to cover cash needs for working capital and capital expenditures for at least the next 12 months. Cash and cash equivalents, the conversion of other working-capital items and borrowings are expected to be sufficient to fund on-going operations.

          On October 12, 2006, we issued and sold convertible senior notes with an aggregate principal amount of $230 million due 2026 (“Notes”), which pay 2.25% interest per annum on the principal amount of the Notes, payable semi-annually in arrears on April 1 and October 1 of each year, beginning on April 1, 2007. In connection with the issuance of the Notes, we incurred approximately $6.2 million of issuance costs, which primarily consisted of investment banker fees, legal and accounting fees. These costs are classified within other assets and are being amortized as a component of interest expense using the straight-line method over the life of the Notes from issuance through October 12, 2011. During the fourth quarter of 2008 and the first quarter of 2009, we repurchased $46.5 million and $9.6 million principal amount of the Notes for approximately $23.2 million and $6.6 million in cash, respectively. See Note 10 of “Notes to Consolidated Financial Statements” of this Annual Report for additional information about the Notes and the repurchase.

          In 2006, 2007 and 2008, our capital expenditures were $45.1 million, $54.2 million and $53.4 million, respectively. Our capital expenditures for these periods were primarily related to manufacturing expansion in our facilities in China and, to a lesser extent, our wafer fabrication facility in the U.S., and an office building in Taiwan. Capital expenditures for 2008 were approximately 12.3% of revenue. Until economic conditions improve, we expect capital expenditures to be approximately 2% of revenue for 2009.

          As of December 31, 2008, we had $320.6 million invested in ARS, which are classified as long-term, trading securities. With the liquidity issues experienced in the global credit and capital markets, our ARS have experienced multiple failed auctions. While we continue to earn and receive interest on these investments at the maximum contractual rate, the estimated fair values of these ARS no longer approximates par value.

          On October 29, 2008, we reached a settlement with UBS AG and affiliates (“UBS AG”), in regard to our ARS portfolio, which gives us the option to “put” the $320.6 million ARS portfolio back to UBS AG at any time from June 30, 2010 through July 2, 2012 at par value in exchange for cash. Upon entering into this settlement, we elected the fair value option and recorded the “put” right at its fair value and a related gain. In addition, we transferred our ARS portfolio from an available-for-sale category to a trading category of investments. Upon transferring the ARS portfolio to a trading category, all of the previously unrealized holding losses included in comprehensive income were recognized in earnings. As a result of categorizing the ARS as trading investments and the election of the fair value option for the “put” right, all future changes in fair value for both of these financial instruments will be recognized in earnings and are expected to offset, thereby creating accounting symmetry at inception of the settlement and during each period until we exercise our “put”

option. See Note 4 of “Notes to Consolidated Financial Statements” and “Risk Factors — Our Auction Rate Securities (“ARS”) are currently illiquid and we cancelled our bank credit facility in the U.S.; therefore, we must rely solely upon existing cash reserves, available foreign credit facilities and funds from existing operations to finance future operations” in Part I, Item 1A of this Annual Report for additional information about our settlement with UBS AG.

          On March 31, 2008, in connection with the acquisition of Zetex, we entered into a $165 million margin loan with UBS Financial Services, Inc., which accrued interest and was secured by our ARS portfolio.

          On November 4, 2008, we accepted an offer of a “no net cost loan,” which replaced the margin loan, from UBS BANK USA (“UBS Bank”), an affiliate of UBS AG and is collateralized by our ARS portfolio. The “no net cost loan” allows us to draw up to 75% of the stated value of our ARS portfolio, as determined by the UBS Bank, and is subject to collateral maintenance requirements. Under the “no net cost loan,” the interest rate we pay on the “no net cost loan” will not exceed the interest rate earned on the pledged ARS portfolio. Subsequent to the agreement, we drew up to the 75% stated value limit, or $213 million of our ARS portfolio, as determined by UBS Bank.

          As of December 31, 2008, the balance of the “no net cost loan” was $213 million and classified as long-term debt. Since we have drawn up to the 75% limit and the stated value of the ARS has decreased, we cannot draw additional funds from the “no net cost loan” until 75% of the stated value of the ARS exceeds $213 million, at which time we can draw additional funds. Although we cannot currently draw additional funds, we are not required to repay any part of the “no net cost loan” that exceeds 75% of the stated value of the ARS portfolio. See Note 10 of “Notes to Consolidated Financial Statements” of this Annual Report for additional information about our “no net cost loan.”

          Discussion of Cash Flows

          Cash and short-term investments have increased from $339.9 million at December 31, 2006, to $379.7 million at December 31, 2007, then decreased to $103.5 million at December 31, 2008. The increase from 2006 to 2007 was primarily due to the short-term investments purchased with proceeds from the $230 million Convertible Senior Notes. The decrease during 2008 was mainly due to the reclassification of our ARS portfolio from short-term to long-term investments.

          Operating Activities

          Net cash provided by operating activities during 2008 was $57.2 million, resulting primarily from $39.0 million of net income in this period, $41.6 million of depreciation and amortization and a $24.9 million reduction in accounts receivables, partially offset by $22.8 million of gain from extinguishment of debt. Net cash provided by operating activities was $90.8 million for 2007 and $72.1 million for 2006.

          Net cash provided by operations decreased by $33.6 million from 2007 to 2008. This decrease resulted primarily from a $20.7 million decrease in net income (from $59.7 million in 2007 to $39.0 million in 2008), a $12.7 million decrease in net working capital, partially offset by a $22.4 million increase in depreciation and amortization expense. We continue to closely monitor our credit terms with our customers, while at times providing extended terms, primarily required by our customers in Asia and Europe.

          Net cash provided by operations increased by $18.7 million from 2006 to 2007. This increase resulted primarily from a $11.5 million increase in net income (from $48.1 million in 2006 to $59.7 million in 2007), a $1.6 million increase in non-cash, share-based compensation expense, and a $7.3 million increase in depreciation and amortization expense, partially offset by a $1.5 million change in net working capital.

          Investing Activities

          Net cash used by investing activities for 2008 was $203.5 million, resulting primarily from $153.2 million in acquisitions, net of cash acquired and $53.2 million in capital expenditures.

          Net cash used by investing activities for 2007 was $88.4 million, resulting primarily from $56.1 million in capital expenditures and $32.5 million in purchase of securities.

          Net cash used by investing activities for 2006 was $325.7 million, resulting primarily from $250.7 million in purchase of securities, $45.7 million in capital expenditures and $29.4 million in acquisitions, net of cash acquired.

          Financing Activities

          Net cash provided by financing activities for 2008 was $196.9 million, resulting primarily from the proceeds of long-term debt of $212.7 million from the no net cost loan, partially offset by $24.5 million in repayments of long-term debt.

          Net cash provided by financing activities for 2007 was $4.7 million, resulting primarily from $7.6 million from stock option exercises in 2007 and repayments of long-term debt, partially offset by $2.8 million in repayments of long-term debt.

          Net cash provided by financing activities for 2006 was $229.0 million, resulting primarily from proceeds of long-term debt of $228.6 million from the convertible senior notes offering.

          Debt instruments

          On March 28, 2008, we entered into a fourth amendment to our U.S. credit agreement with Union Bank of California, N.A. (“Union Bank”) (“Fourth Amended Credit Agreement” or “Revolving Credit Agreement”). Under the Fourth Amended Credit Agreement the Company had available a revolving credit commitment of up to $22.5 million (increased from $20.0 million), including a $5.0 million letter of credit sub-facility and a term loan facility of $5.0 million. As of December 31, 2008, there were no amounts outstanding under the revolving credit commitment and approximately $1.7 million was outstanding under the term loan.

          On February 6, 2009, we paid in full the outstanding balance of approximately $2.5 million on our revolving credit commitment with Union Bank and terminated the Amended and Restated Credit Agreement that governed the revolving credit commitment. On February 11, 2009, we paid in full the outstanding balance of approximately $1.5 million on our Union Bank term loan facility and terminated the Covenant Agreement that governed that facility, which was scheduled to mature on August 29, 2010.

          On March 31, 2008, we obtained from UBS a letter of credit in favor of Diodes FabTech Inc., in an aggregate amount of $165 million (the “Letter of Credit”). In connection with the acquisition of Zetex, we drew $165 million on the Letter of Credit, which accrued interest and was secured by our ARS portfolio.

          On November 4, 2008, we accepted an offer of “no net cost loan,” which replaced the Letter of Credit, from UBS Bank and is collateralized by our ARS portfolio. The “no net cost loan” allows us to draw up to 75% of the stated value of our ARS portfolio, as determined by UBS Bank. Under the “no net cost loan,” the interest rate we pay on the “no net cost loan” will not exceed the interest rate earned on the pledged ARS portfolio. As of December 31, 2008, the balance of the “no net cost loan” was $213 million and it was classified as long-term debt. See “Liquidity and Capital Resources” above and see Note 10 of “Notes to Consolidated Financial Statements” in this Annual Report for additional information about our “no net cost loan.”

          As of December 31, 2008, our Asia and Europe subsidiaries have available lines of credit of up to an aggregate of $49.4 million, with several financial institutions. These lines of credit, except for one Taiwanese credit facility, are collateralized by each subsidiary’s premises, are unsecured, uncommitted and, in some instances, may be repayable on demand. Loans under these lines of credit bear interest at LIBOR or similar indices plus a specified margin. At December 31, 2008, $6.1 million was outstanding on these lines of credit, and the interest rates ranged from 2.0% to 2.8%.

          In October, 2006, we issued and sold convertible senior Notes with an aggregate principal amount of $230 million due 2026, which pay 2.25% interest per annum on the principal amount of the Notes, payable semi-annually in arrears on April 1 and October 1 of each year, beginning on April 1, 2007. Interest will accrue on the Notes from and including October 12, 2006 or from and including the last date in respect of which interest has been paid or provided for, as the case may be, to, but excluding, the next interest payment date or maturity date, as the case may be. Commencing with the six-month period beginning October 1, 2011, and for each six-month period thereafter, we will, on the interest payment date for such interest period, pay contingent interest to the holders of the Notes under certain circumstances and in amounts described in the indenture. For U.S. Federal income tax purposes, we treat, and each holder of the Notes agreed under the indenture to treat, the Notes as contingent payment debt instruments governed by special tax rules and to be bound by our application of those rules to the Notes.

          During the fourth quarter of 2008 and the first quarter of 2009, we repurchased $46.5 million and $9.6 million principal amount of the Notes for approximately $23.2 million and $6.6 million in cash, respectively. Beginning January 1, 2009, we will adopt FSP APB 14-1, which will change how we account for our Notes and will significantly increase our non-cash interest expense. See “Recently Issued Accounting Pronouncements” below for additional information about FSP APB 14-1 and see Note 10 of “Notes to Consolidated Financial Statements” in this Annual Report for additional information about the Notes and the repurchase.

          We may from time to time seek to repurchase our outstanding debt in the open market, in privately negotiated transactions or otherwise. Such repurchases, if any, will depend on prevailing market conditions, our liquidity requirements, contractual restrictions and other factors. The amounts involved may be material.

Off-Balance Sheet Arrangements

          We do not have any transactions, arrangements and other relationships with unconsolidated entities that will affect our liquidity or capital resources. We have no special purpose entities that provided off-balance sheet financing, liquidity or market or credit risk support, nor do we engage in leasing, hedging or research and development services, that could expose us to liability that is not reflected on the face of our financial statements.

Contractual Obligations

          The following table represents our contractual obligations as of December 31, 2008:

		Payments due by period (in thousands)
						Less than												More than
		Total				1 year				1-3 years				3-5 years				5 years

Total obligations		$	441,713			$	12,771			$	9,736			$	7,751			$	411,455

          Per FASB interpretation (“FIN”) No. 48, Accounting for Uncertainty in Income Taxes (“FIN 48”), liabilities are not included in the above contractual obligations as we can not make reasonable estimates of the amount and period in which those tax liabilities would be paid. See “Accounting for income taxes” below and Note 15 of “Notes to Consolidated Financial Statements” of this Annual Report for additional information regarding FIN 48.

Critical Accounting Policies and Estimates

          The preparation of financial statements in conformity with generally accepted accounting principles in the United States of America (“GAAP”) requires that management make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. On an on-going basis, we evaluate our estimates, which are based upon historical experiences, market trends and financial forecasts and projections, and upon various other assumptions that management believes to be reasonable under the circumstances at that certain point in time. Actual results may differ, significantly at times, from these estimates under different assumptions or conditions.

          We believe the following critical accounting policies and estimates affect the significant estimates and judgments we use in the preparation of our consolidated financial statements, and may involve a higher degree of judgment and complexity than others.

          Revenue recognition

          We recognize revenue when there is persuasive evidence that an arrangement exists, when delivery has occurred, when our price to the buyer is fixed or determinable and when collectability of the receivable is reasonably assured. These elements are met when title to the products is passed to the buyers, which is generally when our product is shipped to our customers.

          We reduce revenue in the period of sale for estimates of product returns, distributor price adjustments and other allowances, the majority of which are related to our U.S. operations. Our reserve estimates are based upon historical data as well as projections of revenues, distributor inventories, price adjustments, average selling prices and market conditions. Actual returns and adjustments could be significantly different from our estimates and provisions, resulting in an adjustment to revenues.

          Inventories

          Inventories are stated at the lower of cost or market value. Cost is determined principally by the first-in, first-out method. On an on-going basis, we evaluate our inventory, both finished goods and raw material, for obsolescence and slow-moving items. This evaluation includes analysis of sales levels, sales projections, and purchases by item, as well as raw material usage related to our manufacturing facilities. If our review indicates a reduction in utility below carrying value, we reduce our inventory to a new cost basis. If future demand or market conditions are different than our current estimates, an inventory adjustment may be required, and would be reflected in cost of goods sold in the period the revision is made.

          Accounting for income taxes

          As part of the process of preparing our consolidated financial statements, we are required to estimate our income taxes in each of the tax jurisdictions in which we operate. This process involves using an asset and liability approach whereby deferred tax assets and liabilities are recorded for differences in the financial reporting bases and tax bases of our assets and liabilities. Deferred tax accounting requires that we evaluate net deferred tax assets by jurisdiction to determine if these assets will more likely than not be realized in the foreseeable future. This test requires the consideration of the reversal of temporary differences between book and tax basis, the projection of our taxable income into future years and the use of tax planning strategies to determine if it is more likely than not that we will realize the tax assets. This analysis requires considerable judgment and is subject to change to reflect future events and changes in the tax laws.

          We are involved in various tax matters, some of whose outcome is uncertain. For purposes of evaluating whether or not a tax position is uncertain (i) we presume the tax position will be examined by the relevant taxing authority that has full knowledge of all relevant information, (ii) technical merits of a tax position are derived from authorities such as legislation and statutes, legislative intent, regulations, rulings and case law and their applicability to the facts and circumstances of the tax position, and (iii) each tax position is evaluated without consideration of the possibility of offset or aggregation with other tax positions taken. A tax benefit from an uncertain position may be recognized only if it is “more likely than not” that the position is sustainable, based on its technical merits, and the tax benefit of a qualifying position is the largest amount of tax benefits that is greater than 50% likely of being realized upon ultimate settlement with a taxing authority having full knowledge of all relevant information.

          We adopted the provisions of FIN 48, effective January 1, 2007. As a result of the implementation of FIN 48, we recorded an approximate $2.0 million increase in the liability for unrecognized tax benefits, primarily related to our

foreign subsidiaries, which was accounted for as a reduction to the January 1, 2007 retained earnings balance.

          Allowance for doubtful accounts

          We evaluate the collectability of our accounts receivable based upon a combination of factors, including the current business environment and historical experience. If we are aware of a customer’s inability to meet its financial obligations to us, we record an allowance to reduce the receivable to the amount we reasonably believe we will be able to collect from the customer. For all other customers, we record an allowance based upon the amount of time the receivables are past due. If actual accounts receivable collections differ from these estimates, an adjustment to the allowance may be necessary with a resulting effect on operating expense.

          Goodwill and long-lived assets

          Goodwill is the cost of an acquisition less the fair value of the net assets of the acquired business. As of December 31, 2008, goodwill was $46.5 million. We account for goodwill in accordance with SFAS No. 142 Goodwill and Other Intangible Assets, for which goodwill is tested for impairment at least annually and between annual tests if indicators of potential impairment exist. In 2008, we changed the timing of our annual goodwill impairment testing from December 31 to October 1 to allow us to complete the testing in advance of our year-end closing. The fair value of the reporting units was calculated using the income approach and the market approach. Under the income approach, the fair value of the reporting units was calculated by estimating the present value of associated future cash flows. Under the market approach, the fair value was calculated using the guideline public company method and the mergers and acquisitions method. We determined that the fair value of the reporting units exceeds the carrying value of units, thus indicating that the goodwill was not impaired as of the testing date.

          We assess the impairment of certain long-lived assets at least annually and whenever events or changes in circumstances indicate that the carrying value may not be recoverable in accordance with SFAS No. 144, Accounting for the Impairment or Disposal of Long-Lived Assets. We assess the recoverability of our long-lived and intangible assets by determining whether the unamortized balances can be recovered through undiscounted future net cash flows of the related assets. If such asset is considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the asset exceeds its fair market value using a discounted cash flow analysis.

          Share-based compensation

          We account for share-based compensation in accordance with SFAS No. 123R, Share-Based Payments. We use the Black-Scholes-Merton model, consistent with prior period valuations under SFAS No. 123, Accounting for Stock-Based Compensation, to determine the fair value of stock options on the date of grant. Restricted stock grants are measured based on the fair market value of the underlying stock on the date of grant.

          The amount of compensation expense recognized using the Black-Scholes-Merton model requires us to exercise judgment and make assumptions relating to the factors that determine the fair value of our stock option grants. The fair value calculated by this model is a function of several factors, including the grant price, the expected future volatility, the expected term of the option and the risk-free interest rate of the option. The expected term and expected future volatility of the options require our judgment. In addition, we are required to estimate the expected forfeiture rate and only recognize expense for those stock options expected to vest. We estimate the forfeiture rate based on historical experience and to the extent our actual forfeiture rate is different from our estimate, share-based compensation expense is adjusted accordingly.

          Fair value measurements

          On January 1, 2008, we adopted the methods of fair value as described in SFAS No. 157, Fair Value Measurements, to value our ARS portfolio. SFAS No. 157, among other things, defines fair value, establishes a consistent framework for measuring fair value and expands disclosures for each major asset and liability category measured at fair value on either a recurring or nonrecurring basis. SFAS No. 157 clarifies that fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is market-based measurement that should be determined based on the assumptions that market participants would use in pricing an assets or liability. SFAS No. 157 establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as following:

          Level 1 — Observable inputs such as quoted prices inactive market.

          Level 2 — Inputs other than the quoted prices in active markets that are observable either directly or indirectly.

          Level 3 — Unobservable inputs in which there is little or no market data, which requires the reporting entity to develop its own assumptions.

                             

          Due to lack of observable market quotes on our ARS portfolio and “put” option, we utilized a valuation model that relies exclusively on Level 3 inputs including those that are based on factors that reflect assumptions market participants would use in pricing, including, among others: relevant future market conditions including those that are based on the expected cash flow streams, the underlying financial condition and credit quality of the issuer and bond insurer, the percent of the Federal Family Education Loan Program (“FFELP”) guaranty, and the maturity of the securities, as well as the market activity of similar securities. The valuation of our ARS investment portfolio is subject to uncertainties that are difficult to predict. Factors that may impact our valuation include changes to credit rating of the securities as well as to the underlying assets supporting those securities, rates of default of the underlying assets, underlying collateral value, discount rates, counterpart risk and ongoing strength and quality of market credit and liquidity.

          Defined benefit plan

          We maintain pension plans covering certain of our employees in the United Kingdom (“U.K.”) and Germany. For financial reporting purposes, the net pension and supplemental retirement benefit obligations and the related periodic pension costs are calculated based upon, among other things, assumptions of the discount rate for plan obligations, estimated return on pension plan assets and mortality rates. These obligations and related periodic costs are measured using actuarial techniques and assumptions. The projected unit credit method is the actuarial cost method used to compute the pension liabilities and related expenses.

          Asset retirement obligations

          We recognize assets retirement obligations (“ARO’s”) when incurred, with the initial measurement at fair value. These liabilities are accreted to full value over time through charges to income. In addition, asset retirement costs are capitalized as part of the related asset’s carrying value and are depreciated over the assets respective useful life. Our ARO’s consist primarily of estimated costs to return leased property to its original condition. The liabilities of $0.3 million for ARO’s are included in our consolidated balance sheet as other long-term liabilities.

          Investment in joint venture

          Investment in joint ventures over which we have the ability to exercise significant influence and that, in general, are at least 20 percent owned are stated at cost plus equity in undistributed net income (loss) of the joint venture. These investments are evaluated for impairment in accordance with the requirements of Accounting Principles Board Opinion No. 18, The Equity Method of Accounting for Investments in Common Stock. An impairment loss would be recorded whenever a decline in the value of an equity investment below its carrying amount is determined to be other than temporary. In judging “other than temporary,” we would consider the length of time and extent to which the fair value of the investment has been less than the carrying amount of the investment, the near-term and longer-term operating and financial prospects of the investee, and our long-term intent of retaining the investment in the investee. The value of our investment in joint venture of $0.6 million is included in our consolidated balance sheet as other assets.

          Contingencies

          From time to time, we are involved in a variety of legal matters that arise in the normal course of business. Based on information available, we evaluate the likelihood of potential outcomes. In accordance with SFAS No 5, Accounting for Contingencies, we record the appropriate liability when the amount is deemed probable and reasonably estimable. In addition, we do not accrue for estimated legal fees and other directly related costs as they are expensed as incurred.

Recently Issued Accounting Pronouncements

          In November 2008, the FASB ratified the EITF consensus on EITF Issue No. 08-7, Accounting for Defensive Intangible Assets. This pronouncement clarifies the accounting for certain separately identifiable intangible assets which an acquirer does not intend to actively use but intends to hold to prevent its competitors from obtaining access to them. EITF Issue No. 08-7 requires an acquirer in a business combination to account for a defensive intangible asset as a separate unit of accounting which should be amortized to expense over the period the asset diminishes in value. EITF Issue No. 08-7 is effective for financial statements issued for fiscal years beginning after December 15, 2008. Early adoption is prohibited. We are currently evaluating the future impacts and required disclosures of this pronouncement.

          In November 2008, the FASB ratified the EITF consensus on EITF Issue No. 08-6, Equity Method Investment Accounting Considerations. This pronouncement clarifies the accounting for certain transactions and impairment considerations involving equity method investments. EITF Issue No. 08-6 is effective for financial statements issued for fiscal years beginning after December 15, 2008. Early adoption is prohibited. We are currently evaluating the future impacts and required disclosures of this pronouncement.

          In June 2008, the FASB ratified the EITF consensus on EITF Issue No. 07-5, Determining Whether an Instrument (or Embedded Feature) Is Indexed to an Entity’s Own Stock. This pronouncement clarifies the determination of whether an instrument (or an embedded feature) is indexed to an entity’s own stock, which would qualify as a scope exception in paragraph 11(a) of SFAS No. 133, Accounting for Derivative Instruments and Hedging Activities. EITF Issue No. 07-05 is effective for financial statements issued for fiscal years beginning after December 15, 2008. Early adoption is prohibited. We are currently evaluating the future impacts and required disclosures of this pronouncement.

          In June 2008, the FASB issued FASB Staff Position (“FSP”) EITF 03-6-1, Determining Whether Instruments Granted in Share-Based Payment Transactions Are Participating Securities. This pronouncement provides that unvested share-based payment awards that contain non-forfeitable rights to dividends or dividend equivalents (whether paid or unpaid) are participating securities and shall be included in the computation of earnings per share (“EPS”) pursuant to the two-class method. FSP EITF 03-6-1 is effective for financial statements issued for fiscal years beginning after December 15, 2008. Upon adoption, a company is required to retrospectively adjust its EPS data (including any amounts related to interim periods, summaries of earnings and selected financial data) to conform with the provisions of FSP EITF 03-6-1. We are currently evaluating the future impacts and required disclosures of this pronouncement.

          In May 2008, the FASB issued FSP APB 14-1, Accounting for Convertible Debt Instruments That May Be Settled in Cash upon Conversion (Including Partial Cash Settlement). This pronouncement clarifies that convertible debt instruments that may be settled in cash upon conversion are not addressed by paragraph 12 of Accounting Principles Board Opinion No. 14, Accounting for Convertible Debt and Debt Issued with Stock Purchase Warrants. FSP APB 14-1 also specifies that issuers of such instruments should separately account for the liability and equity components in a manner that will reflect the entity’s nonconvertible debt borrowing rate. Previous guidance provided for accounting of this type of convertible debt instruments entirely as debt. FSP APB 14-1 is effective for financial statements issued for fiscal years beginning after December 15, 2008. We have considered the future impacts and required disclosures of this pronouncement and believe it will result in material adjustments in accounting for our originally issued $230 million convertible senior notes issued in October 2006. Furthermore, all adjustments are required to be made retrospectively as of the date of issuance of the convertible senior notes and therefore, will be treated as if convertible senior notes have always been accounted for in accordance with this pronouncement. This retrospective treatment will require us to restate the amounts included in previously issued financial statements in future filings. Preliminarily, when we restate our consolidated statements of income for the years 2007 and 2008, we expect to increase our non-cash interest expense and decrease its deferred tax expense by approximately $10 million and approximately $4 million for each year, respectively. Also, our $22.8 million pre-tax gain on extinguishment of debt and deferred tax expense for 2008 will be reduced by approximately $7 million (non-cash) and approximately $3 million, respectively. In addition, when we restate our December 31, 2008 balance sheet we expect to reduce our long-term debt from $183.5 million to approximately $147 million. The deferred tax liability associated with the convertible debt instrument will also decrease by approximately $15 million. For 2009, we expect to record an additional non-cash interest expense of approximately $8 to $9 million. This amount is less than in 2007 and 2008 due to the extinguishment of $46.5 million and $9.6 million par value convertible senior notes in December 2008 and January 2009, respectively.

          In February 2008, the FASB issued FSP FAS 157-2, Effective Date of FASB Statement No. 157. This

pronouncement delays the effective date of SFAS No. 157, Fair Value Measurements, for all non-financial assets and non-financial liabilities, except those recognized or disclosed at fair value in the financial statements on a recurring basis, until January 1, 2009. We are currently evaluating the future impacts and required disclosures of this pronouncement.

          In December 2008, the FASB issued FSP FAS 132R-1, Employers’ Disclosures about Postretirement Benefit Plan Assets. This pronouncement provides additional guidance regarding disclosures about plan assets of defined benefit pension or other postretirement plans. FSP FAS 132R-1 is effective for financial statements issued for fiscal years beginning after December 15, 2009. We are currently evaluating the future impacts and required disclosures of this pronouncement.

          In April 2008, the FASB issued FSP FAS 142-3, Determination of the Useful Life of Intangible Asset. This pronouncement amends the factors that should be considered in developing renewal or extension assumptions used to determine the useful life of a recognized intangible asset under SFAS No. 142, Goodwill and Other Intangible Assets. The intent of this FSP is to improve the consistency between the useful life of a recognized intangible asset under SFAS No. 142 and the period of expected cash flows used to measure the fair value of the asset under SFAS No. 141R, Business Combinations, and other accounting principles generally accepted in the U.S. FSP FAS 142-3 is effective for financial statements issued for fiscal years beginning after December 15, 2008, and interim periods within those fiscal years. Early adoption is prohibited. The guidance for determining the useful life of a recognized intangible asset in this FSP shall be applied prospectively to intangible assets acquired after the effective date. The disclosure requirements shall be applied prospectively to all intangible assets recognized as of, and subsequent to, the effective date. We are currently evaluating the future impacts and required disclosures of adopting this pronouncement.

          In March 2008, the FASB issued SFAS No. 161, Disclosures about Derivative Instruments and Hedging Activities — an Amendment of SFAS No. 133. This pronouncement requires that objectives for using derivatives instruments be disclosed in terms of underlying risk and accounting designation. The fair value of derivative instruments and their gains and losses will need to be presented in tabular format in order to present a more complete picture of the effects of using derivative instruments. SFAS No. 161 is effective for financial statements issued for fiscal years beginning after November 15, 2008. We are currently evaluating the future impacts and required disclosures of adopting this pronouncement.

          In December 2007, the FASB issued SFAS No. 141R, Business Combinations, which changes how business acquisitions are accounted. This pronouncement requires the acquiring entity in a business combination to recognize all (and only) the assets acquired and liabilities assumed in the transaction and establishes the acquisition-date fair value as the measurement objective for all assets acquired and liabilities assumed in a business combination. Among the more significant changes in the accounting for acquisitions are the following: i) Transaction costs will generally be expensed. Certain such costs are presently treated as costs of the acquisition; ii) IPR&D will be accounted for as an asset, with the cost recognized as the research and development is realized or abandoned. IPR&D is presently expensed at the time of the acquisition; iii) Contingencies, including contingent consideration, will generally be recorded at fair value with subsequent adjustments recognized in operations. Contingent consideration is presently accounted for as an adjustment of purchase price; and iv) Decreases in valuation allowances on acquired deferred tax assets will be recognized in operations. Such changes previously were considered to be subsequent changes in consideration and were recorded as adjustments to goodwill. SFAS No. 141R is effective for business combinations and adjustments to an acquired entity’s deferred tax asset and liability balances occurring after December 31, 2008. Early adoption is prohibited. We are currently evaluating the future impacts and required disclosures of this pronouncement.

          In December 2007, the FASB issued SFAS No. 160, Noncontrolling Interests in Consolidated Financial Statements, an amendment of ARB No. 51. This pronouncement establishes new standards governing the accounting for and reporting of noncontrolling interests (“NCIs”) in partially owned consolidated subsidiaries and the loss of control of subsidiaries. Certain provisions of this standard indicate, among other things, that NCIs (previously referred to as minority interests) be treated as a separate component of equity, not as a liability; that increases and decreases in the parent’s ownership interest, that leave control intact, be treated as equity transactions, rather than as step acquisitions or dilution gains or losses; and that losses of a partially owned consolidated subsidiary be allocated to the NCIs even when such allocation might result in a deficit balance. This standard also requires changes to certain presentation and disclosure requirements. SFAS No. 160 is effective for financial statements issued beginning January 1, 2009. The provisions of the standard are to be applied to all NCIs prospectively, except for the presentation and disclosure requirements, which are to be applied retrospectively to all periods presented. After adoption, noncontrolling interests ($7.2 million and $9.5 million as of December 31, 2007 and 2008, respectively) will be classified as stockholders’ equity, a change from its current classification

between liabilities and stockholders’ equity. We are currently evaluating the future impacts and required disclosures of this pronouncement.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

          Foreign Currency Risk. We face exposure to adverse movements in foreign currency exchange rates, primarily in Asia and Europe. Our foreign currency risk may change over time as the level of activity in foreign markets grows and could have a material adverse impact upon our financial results. Certain of our assets, including certain bank accounts and accounts receivable, and liabilities exist in non-U.S. dollar denominated currencies, which are sensitive to foreign currency exchange fluctuations. These currencies are principally the Chinese Yuan, the Taiwanese dollar and the British Pound Sterling and, to a lesser extent, the Japanese Yen, the Euro and the Hong Kong dollar.

          Historically, because of the relatively small size and nature of each individual currency exposure, we did not regularly employ hedging techniques designed to mitigate foreign currency exposures. During the second quarter of 2008, with the acquisition of Zetex, we adopted forward exchange contracts, designated as foreign-currency cash flow hedges, to reduce the potentially adverse effects of foreign-currency exchange rate fluctuations that occur in the normal course of business. We use forward exchange contracts to hedge, thereby attempting to reduce our overall exposure to the effects of currency fluctuations on cash flows. We do not permit speculation in financial instruments for profit on the exchange rate price fluctuation, trading in currencies for which there are no underlying exposures, or entering into trades for any currency to intentionally increase the underlying exposure. As part of our overall strategy to manage the level of exposure to the risk of foreign currency exchange rate fluctuations, primarily to changes in the value of the Euro and the British Pound Sterling, we hedge a portion of our foreign currency exposures anticipated over the ensuing twelve-months to two-year periods. In doing so, we use foreign currency exchange contracts that generally have maturities of three months to two years to provide continuing coverage throughout the hedging period. As of December 31, 2008, we have forward contracts, primarily relating to the operations acquired from Zetex, of approximately $18 million that mature monthly over the next twelve months. Currently we do not intend to enter into additional forward contracts.

          If the Chinese Yuan, the Taiwanese dollar, the Euro and the British Pound Sterling were to strengthen or weaken by 1.0% against the U.S. dollar, we would experience currency gain of approximately $0.2 million and currency loss of approximately $0.2 million, respectively. In the future, we may enter into hedging arrangements designed to mitigate foreign currency fluctuations. The Chinese government has begun to permit the Chinese Yuan to float more freely compared to other world currencies. Should the Chinese government allow a significant Chinese Yuan appreciation, and we do not take appropriate means to offset this exposure, the effect could have a material adverse impact upon our financial results.

          During the second quarter of 2008, with the acquisition of Zetex, we adopted a contributory defined benefit plan that covers certain employees in the United Kingdom and Germany. The defined benefit plan is closed to new entrants and frozen with respect to future benefit accruals. The retirement benefit is based on the final average compensation and service of each eligible employee. On the acquisition date, we determined the fair value of the defined benefit plan assets and utilize an annual measurement date of December 31. At subsequent measurement dates, defined benefit plan assets will be determined based on fair value. Defined benefit plan assets consist primarily of high quality corporate bonds that are denominated in the currency in which the benefits will be paid and that have terms to maturity approximating to the terms of the related pension liability. The net pension and supplemental retirement benefit obligations and the related periodic costs are based on, among other things, assumptions of the discount rate, estimated return on plan assets and mortality rates. These obligations and related periodic costs are measured using actuarial techniques and assumptions. The projected unit credit method is the actuarial cost method used to compute the pension liabilities and related expenses. As of December 31, 2008, the plan is underfunded and a liability of $12 million is reflected in our consolidated financial statements as noncurrent liabilities. The amount recognized in accumulated other comprehensive income was a net loss of $4.7 million and the weighted-average discount rate assumption used to determine benefit obligations as of December 31, 2008 was 6.4%. The asset value of the defined benefit plan has been volatile in recent months due primarily to wide fluctuations in the United Kingdom’s equity markets and bond markets. See “Risk Factors — Due to the recent and ongoing fluctuations in the United Kingdom’s equity markets and bond markets, changes in actuarial assumptions for our Company’s defined benefit plan could increase the volatility of the plan’s asset value, require us to increase cash contributions to the plan and could have a negative impact on our results of operations and profitability.” in Part I, Item 1A of this Annual Report for further information.

          Interest Rate Risk. We have credit facilities with financial institutions in Asia and Europe as well as other debt instruments with interest rates equal to LIBOR or similar indices plus a negotiated margin. On February 6, 2009, we terminated our credit facilities with Union Bank. A rise in interest rates could have an adverse impact upon our cost of working capital and our interest expense. As a matter of policy, we do not enter into derivative transactions for speculative purposes. As of December 31, 2008, our outstanding debt under our interest-bearing credit agreements was $402.0 million, including $183.5 million convertible notes with a fixed interest rate of 2.25% and $212.7 million under our “no net cost loan.” Based on an increase or decrease in interest rates by 1.0% for the year, our annual interest rate expense would increase or decrease by approximately $0.1million due to the fact that any increase in interest expense related to our “no net cost loan” will be offset by interest earned on our ARS portfolio.

          Political Risk. We have a significant portion of our assets in mainland China, Taiwan and the United Kingdom. The possibility of political conflict between the any of these countries or with the U.S. could have a material adverse impact upon our ability to transact business through these important business channels and to generate profits. See “Risk Factors” — Risks Related to our International Operations” in Part I, Item 1A of this Annual Report for further information.

          Liquidity Risk. As of December 31, 2008, we had $320.6 million invested in ARS, which are instruments that historically provided liquidity through a Dutch auction process that resets the applicable interest rate at pre-determined calendar intervals. These mechanisms historically have allowed existing investors to roll over their holdings and continue to own the respective securities or to liquidate their holdings by selling their securities at par value.

          On October 29, 2008, we reached a settlement with UBS AG and affiliates (“UBS AG”), in regard to our ARS portfolio, which gives us the option to “put” the $320.6 million ARS portfolio back to UBS AG at any time from June 30, 2010 through July 2, 2012 at par value in exchange for cash. Upon entering into this settlement, we elected the fair value option and recorded the “put” right at its fair value and a related gain. In addition, we transferred our ARS portfolio from an available-for-sale category to a trading category of investments. Upon transferring the ARS portfolio to a trading category, all of the previously unrealized holding losses included in comprehensive income were recognized in earnings. As a result of categorizing the ARS as trading investments and the election of the fair value option for the “put” right, all future changes in fair value for both of these financial instruments will be recognized in earnings and are expected to offset, thereby creating accounting symmetry at inception of the settlement and during each period until we exercise our “put” option. See Note 4 of “Notes to Consolidated Financial Statements” and “Risk Factors — Our Auction Rate Securities (“ARS”) are currently illiquid and we cancelled our bank credit facility in the U.S.; therefore, we must rely solely upon existing cash reserves, available foreign credit facilities and funds from existing operations to finance future operations” in Part I, Item 1A of this Annual Report for additional information about our settlement with UBS AG.

          Inflation Risk. Inflation did not have a material effect on net sales or net income in fiscal year 2008. During the third and fourth quarter of 2008, we were affected by the recent global economic weakness and financial market uncertainty, which have negatively affected our net sales and operating results. The success of our business depends, among other factors, on the strength of the global economy and the stability of the financial markets, which in turn affect our customers’ demand for our products, the ability of our customers to meet their payment obligations, the likelihood of customers canceling or deferring existing orders and end-user consumers’ demand for items containing our products in the end-markets we serve.

Item 8. Financial Statements and Supplementary Data

          See Part IV, Item 15 “Exhibits and Financial Statement Schedules” for the Company’s Consolidated Financial Statements and the notes and schedules thereto filed as part of this Annual Report.

Item 9. Changes In and Disagreements With Accountants on Accounting and Financial Disclosure

          Not Applicable.

Item 9A. Controls and Procedures

Disclosure Controls and Procedures

          Our Chief Executive Officer, Keh-Shew Lu, and Chief Financial Officer, Carl C. Wertz, with the participation of the Company’s management, carried out an evaluation of the effectiveness of our disclosure controls and procedures pursuant to Exchange Act Rule 13a-15(e). Based upon that evaluation, the Chief Executive Officer and the Chief Financial Officer believe that, as of the end of the period covered by this report, our disclosure controls and procedures are effective at the reasonable assurance level to ensure that information required to be included in this report is:

	•		recorded, processed, summarized and reported within the time period specified in the Commission’s rules and forms; and
	•		accumulated and communicated to our management, including the Chief Executive Officer and the Chief Financial Officer, to allow timely decisions required disclosure.

          Disclosure controls and procedures, no matter how well designed and implemented, can provide only reasonable assurance of achieving an entity’s disclosure objectives. The likelihood of achieving such objectives is affected by limitations inherent in disclosure controls and procedures. These include the fact that human judgment in decision-making can be faulty and that breakdowns in internal control can occur because of human failures such as simple errors, mistakes or intentional circumvention of the established processes.

Management’s Annual Report on Internal Control Over Financial Reporting

          Management is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is a process designed by, or under the supervision of, the Company’s Chief Executive Officer and the Chief Financial Officer and implemented by the Company’s Board of Directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles in the United States of America.

          The Company’s internal control over financial reporting includes those policies and procedures that: (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles in the United States of America, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized 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 misstatements. 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.

          Under the supervision and with the participation from management, including our Chief Executive Officer and the Chief Financial Officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework and criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”). This evaluation included review of the documentation of controls, testing of operating effectiveness of controls and a conclusion on this evaluation. Based on this evaluation, management concluded that the Company’s internal control over financial reporting was effective as of December 31, 2008. As permitted by the rules of the SEC, we have excluded Zetex from our annual assessment of the effectiveness of internal control over financial reporting for the year ending December 31, 2008, the year of acquisition. As of December 31, 2008, Zetex’s financial statements constitute approximately 16.8% of our consolidated assets and constituted approximately 15.6% of our consolidated revenue for the year ended December 31, 2008.

          Moss Adams LLP, an independent registered public accounting firm, has audited and reported on the consolidated financial statements of Diodes Incorporated and on the effectiveness of our internal controls over financial reporting. The reports of Moss Adams LLP are contained in this Annual Report.

Changes in Controls over Financial Reporting

          There was no change in our internal control over financial reporting, known to the Chief Executive Officer or the Chief Financial Officer that occurred during the last fiscal quarter covered by this report that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting, except as follows:

          On June 9, 2008, we acquired Zetex, which constitutes approximately 16.8% of our consolidated assets as of December 31, 2008 and constituted approximately 15.6% of our consolidated revenue for the year ended December 31, 2008.

As permitted by the rules of the SEC, we have excluded Zetex from our annual assessment of the effectiveness of internal control over financial reporting for the year ending December 31, 2008, the year of acquisition. Management continues to evaluate Zetex’s internal controls over financial reporting. See “Risk Factors — Our management certification and auditor attestation regarding the effectiveness of our internal control over financial reporting as of December 31, 2008 excluded the operations of Zetex. If we are not able to integrate Zetex operations into our internal control over financial reporting, our internal control over financial reporting may not be effective.” in Part I, Item 1A of this Annual Report for additional information.

We have audited the accompanying consolidated balance sheets of Diodes Incorporated and Subsidiaries (the “Company”) as of December 31, 2007 and 2008 and the related consolidated statements of income, stockholders’ equity and cash flows for each of the years in the three-year period ended December 31, 2008. We also have audited the Company’s internal control over financial reporting as of December 31, 2008, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. The Company’s management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Annual Report on Internal Control Over Financial Reporting appearing under Item 9A. Our responsibility is to express an opinion on these consolidated financial statements and an opinion on the Company’s internal control over financial reporting based on our 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 consolidated financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the consolidated 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 obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also include 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 purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide 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 expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the consolidated financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. 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.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the consolidated financial position of Diodes Incorporated and Subsidiaries as of December 31, 2007 and 2008, and the results of their operations and their cash flows for each of the years in the three-year period ended December 31, 2008, in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, Diodes Incorporated and Subsidiaries, maintained, in all material respects, effective internal control over financial reporting as of December 31, 2008, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.

As discussed in Note 1 to the consolidated financial statements, effective January 1, 2008, the Company adopted Statement of Financial Accounting Standards (FASB) No. 157, Fair Value Measurements. As discussed in Note 1 to the consolidated financial statements, effective January 1, 2007, the Company adopted FASB Interpretation No. 48, Accounting for Uncertainty in Income Taxes — an interpretation of FASB No. 109.

As described in Management’s Annual Report on Internal Control over Financial Reporting appearing under Item 9A, management has excluded from its assessment of internal control over financial reporting as of December 31, 2008, certain elements of the internal control over financial reporting of Zetex Plc (“Zetex”), because Zetex was acquired by the Company in a purchase business combination during 2008. Subsequent to the acquisition, certain elements of the acquired business’s internal control over financial reporting and related processes were integrated into the Company’s existing systems and internal control over financial reporting. Those controls that were not integrated have been excluded from management’s assessment of the effectiveness of internal control over financial reporting as of December 31, 2008.

We have also excluded these elements of the internal control over financial reporting of the acquired business from our audit of the Company’s internal control over financial reporting. The excluded elements represent controls over accounts of approximately 16.8% of the Company’s consolidated assets as of December 31, 2008, and 15.6% of consolidated revenue for the year then ended.
