SEGMENT INFORMATION AND ENTERPRISE-WIDE DISCLOSURES
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 Asia, North America and Europe. We aggregate our products in a single segment because the products have similar economic characteristics, are similar in production process and manufacturing flow, and share the same customers and target end-equipment markets. See Note 15 of “Notes to Consolidated Financial Statements” of this Annual Report for addition information.
OUR INDUSTRY
Semiconductors are critical components used in the manufacture of a broad range 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, communications, industrial and automotive sectors.
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, China packaging, assembly and test 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, we typically operated our Shanghai manufacturing facilities at near full capacity, while at the same time expanding that capacity to meet our growth objectives. In 2011, we established an additional manufacturing facility for semiconductor packaging, assembly and test in Chengdu, China. Additionally, the Shanghai and Chengdu locations of our manufacturing operations provide us with access to a workforce at a relatively low overall cost base while enabling us to better serve our leading customers, many of which are located in Asia.
Integrated packaging expertise – Our expertise in designing and manufacturing innovative and proprietary packaging solutions enables us to package a variety of different device functions into an assortment of packages ranging from miniature chip-scale packaging to packages that integrate multiple separate discrete and/or analog chips into a single semiconductor product called an array. Our ability to design and manufacture multi-chip semiconductor solutions as well as advanced integrated devices 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 LED televisions, LCD panels, set-top boxes and consumer portables such as smartphones, tablets and notebooks.
Broad customer base and diverse end-markets – Our customers are comprised of leading OEMs as well as major EMS providers. Overall, we serve approximately 140 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 susceptible to market fluctuations driven by either specific customers or specific end-user applications.
Customer focused product development – Effective collaboration with our customers and a commitment to customer service are essential elements of our business. We believe focusing on dependable delivery and support tailored to specific end-user applications has fostered deep customer relationships and created a key competitive advantage for us in the highly fragmented discrete, logic and analog semiconductor marketplace. We believe our close relationships with our customers have provided us with keener insight into our customers’ product needs. This results in a stronger demand for 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 experience – The members of our executive team average well over 20 years of industry experience, and the length of their service has created significant institutional insight into our markets, our customers and our operations. Our executive officers have an average of over 28 years experience in the semiconductor industry.
In 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 35 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, Richard D.

Also in 2008, Julie Holland, Vice President of Worldwide Analog Products, came to us from TI with over 20 years of relevant industry experience. In 2011, we hired Clay Beltran, Vice President, Corporate Supply Chain/Planning, Outsourcing, and Quality, who came to us from Semtech Corporation with over 15 years of relevant industry experience.
OUR STRATEGY
Our strategy is to continue to enhance our position as a leading global designer, manufacturer and supplier of high-quality application specific standard semiconductor products, utilizing our innovative and cost-effective packaging technology and leveraging our process expertise and design excellence to achieve above-market profitable growth.
The principal elements of our strategy include the following:
Continue to rapidly introduce innovative discrete, logic 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 LCD and LED televisions and panels, set-top boxes, portables such as smartphones, tablets and notebooks along with other consumer electronics and computing devices. During 2011, we achieved many significant new design wins at 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 well-defined product solutions is critically important in maintaining and extending our market share in the highly competitive semiconductor marketplace. See “Risk Factors –  Obsolete inventories as a result of changes in demand for our products and change in life cycles of our products could adversely affect our business, results of operations and financial condition.”  in Part I, Item 1A of this Annual Report for additional information.
Expand our available market opportunities – We believe we have many paths to increasing our addressable market opportunity. From a product perspective, we intend to continue expanding our portfolio by developing derivative and enhanced performance devices that target adjacent markets and end-equipments. We will continue to cultivate new and emerging customers within our targeted markets, further increasing our already broad customer base. As we focus on new customers, we try to expand our product portfolio penetration within these new, as well as existing, customers. As we expand our extensive range of high power efficiency and small form factor packages, we plan to introduce new and existing product functions in these new packages to allow an even greater market range.
Maintain intense customer focus – We intend to continue to strengthen and deepen our customer relationships. We believe that continued focus on customer service is important and will help to increase our net sales, operating performance and overall market share. 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 further reduce our design cycle time in order to quickly provide our customers with innovative products. Additionally, to support our customer-focused strategy, we historically expand our sales force and field application engineers, particularly in Asia and Europe, during periods of growth.
Enhance cost competitiveness – A key element of our success is our overall low-cost manufacturing 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. In 2011, we expanded our capacity further by establishing an additional manufacturing facility for semiconductor packaging, assembly and test in Chengdu, China. Historically, we typically operate our Shanghai facilities at near full utilization rates and focus on increasing production yields, in order to achieve meaningful economies of scale.
Pursue selective strategic acquisitions – As part of our strategy to expand our semiconductor product offerings and to maximize our market opportunities, we may acquire discrete, logic, analog or mixed-signal technologies, product lines or companies in order to enhance our portfolio and accelerate our new product offerings. During 2011, we announced an agreement to invest in Eris Technology Corporation, which expands our existing relationship with Eris as a supplier of assembly and test services. This investment allows Eris to increase its capacity in specific packages as a complement to our internal manufacturing capacity. See “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, which could adversely affect our business, results of operations and financial condition”  in Part I, Item 1A of this Annual Report for additional information.

MANUFACTURING OPERATIONS AND FACILITIES
We operate two manufacturing facilities located in Shanghai, China, one in Neuhaus, Germany and are developing a fourth facility in Chengdu, China. Our wafer fabrication facilities are located near Kansas City, Missouri and near Manchester, U.K. Our facilities in Shanghai and Neuhaus are packaging, assembly and test manufacturing sites, as is the facility being developed in Chengdu. Our Kansas City facility includes a 125mm and 150mm wafer fabrication line, and our Manchester facility includes a 150mm wafer fabrication line.
During 2010, we announced an investment agreement with the Management Committee of the Chengdu Hi-Tech Industrial Development Zone (the “CDHT”). Under this agreement, we have agreed to form a joint venture with a Chinese partner, Chengdu Ya Guang Electronic Company Limited, to establish a semiconductor manufacturing facility for surface mount component production, assembly and test in Chengdu, China. We initially will own at least 95% of the joint venture. The manufacturing facility will be developed in phases over a ten year period, and we expect to contribute at least $48 million to the joint venture in installments during the first three years. The CDHT will grant the joint venture a fifty year land lease, provides temporary facilities for up to three years at a subsidized rent while the joint venture builds the manufacturing facility and provides corporate and employee tax incentives, tax refunds, subsidies and other financial support to the joint venture and its qualified employees. If the joint venture fails to achieve specified levels of investment, the investment agreement allows for a renegotiation as well as the option to repay a portion of such financial support. This is a long-term, multi-year project that will provide us additional capacity as needed. As of December 31, 2011, we have invested approximately $25 million of which $18 million were for capital expenditures. See “Risk Factors— In 2010, we established a joint venture to build a semiconductor facility in Chengdu, China. We are required to contribute at least $48 million to the joint venture during the first three years with additional contributions thereafter, as well as a substantial amount of time and resources to establish and operate the joint venture. Any failure to meet any such requirements, delays or unforeseen circumstances may cause us to incur penalties or require us to contribute additional expenses or resources and, as a result, could have an adverse effect on our operating efficiencies, results of operations and financial conditions.”  in Part I, Item 1A of this Annual Report for additional information.
For the years ending December 31, 2011 and 2010, we invested approximately $64 million and $69 million, respectively, in plant and state-of-the-art equipment in China ($348 million total investment in China from inception). Our facilities in China manufacture product for sale by our U.S., Europe and Asia operations, and also sell capacity to a select group of external customers. For the years ending December 31, 2011 and 2010, our capital expenditures were approximately $83 million and $87 million, respectively, in equipment, primarily related to manufacturing expansion in our facilities in China.
Our manufacturing processes use many raw materials, including silicon wafers, aluminum and copper lead frames, gold and copper wire and other metals, molding compounds and various chemicals and gases. 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 reputation with customers, results of operations and financial condition 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 for additional information.
Our corporate headquarters are located in Plano, Texas. We also lease or own properties around the world for use as sales and administrative offices, research and development centers, manufacturing facilities, warehouses and logistics centers. The size and/or location of these properties can change from time to time based on our business requirements. See “Properties” in Part I, Item 2 of this Annual Report for additional information.
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 an accurate 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 miniature and power efficient packaging technologies.
Our initial product patent portfolio was primarily composed of discrete technologies. In the late 1990s, our engineers began to research and develop innovative packaging technologies, which produced several important breakthroughs and patents, such as the PowerDI â  series of packaging technology to foster our growth in the semiconductor industry.
PowerDI is a registered trademark of Diodes Incorporated
We acquired Anachip Corp. in early 2006, a fabless semiconductor company, which initiated our presence in the analog product market with a portfolio of standard linear and low dropout regulator products, among others.
Through our acquisition of the assets of APD Semiconductor, Inc. in late 2006, we acquired the SBR® patents and trademark. SBR® is a state-of-the-art integrated circuit wafer processing technology, 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 has produced a breakthrough in rectifier technology.
In 2008, we acquired Zetex, which subsequently increased our available discrete and analog technologies with 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 currently 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, reduction in our intellectual property rights and a negative impact on our business, results of operations and financial condition.”  in Part I, Item 1A of this Annual Report for additional information.
COMPETITION
Numerous semiconductor manufacturers and distributors serve the discrete, logic and analog semiconductor components market, making competition intense. Some of our larger competitors include Fairchild Semiconductor Corporation, Infineon Technologies A.G., International Rectifier Corporation, NXP Semiconductors N.V., ON Semiconductor Corporation, Rohm Electronics USA, LLC, Toshiba Corporation and Vishay Intertechnology, Inc., many of which have greater financial, marketing, distribution and other resources. Accordingly, 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 products, 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, results of operations and financial condition.”  in Part I, Item 1A of this Annual Report for additional information.
ENGINEERING AND RESEARCH AND DEVELOPMENT
Our engineering and research and development groups consist of applications, circuit design, and product development engineers who assist in determining the direction of our future product lines. One of their key functions is to work closely with market-leading customers to further refine, expand and improve our product portfolio within our target 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.
Product development engineers work directly with our semiconductor circuit design and layout engineers who develop die designs for products that match our customers’ requirements. We have the capability to capture the customers’ electrical and packaging requirements and translate those requirements into product specifications which can then be designed and manufactured to support customers’ end-system applications.
For the years ended December 31, 2011, 2010 and 2009, Company-sponsored investment in research and development activities was approximately $27 million, $27 million and $24 million, respectively. As a percentage of net sales, research and development expense was approximately 4%, 4% and 6% for 2011, 2010 and 2009, respectively. The dollar amount increase in 2011 and 2010 was mainly due to increased personnel costs, engineering supplies and material purchases as a result of increased activity compared to 2009.

EMPLOYEES
As of December 31, 2011, we employed a total of 4,499 employees, of which 3,651 of our employees were in Asia, 348 were in the U.S. and 500 were in Europe. None of our employees in Asia or the U.S. 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, finance and management personnel required to operate our business successfully, which could adversely affect on our business, results of operations and financial condition.”  in Part I, Item 1A 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 the U.K. where our wafer fabrication facilities are located, and in China and Germany where our packaging, assembly and test 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, 2011, 2010 and 2009, our capital expenditures for environmental controls have not been material. As of December 31, 2011, there were no known environmental claims or recorded liabilities. See “Risk Factors— We are subject to many environmental laws and regulations that could result in significant expenses and could adversely affect our business, results of operations and financial condition.”  in Part I, Item 1A of this Annual Report for additional information.
CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS
We conduct business with one related party company, Lite-On Semiconductor Corporation and its subsidiaries and affiliates (collectively, “LSC”). LSC is our largest stockholder, owning 18% of our outstanding Common Stock as of December 31, 2011. We also conduct business with one significant company, Keylink International (B.V.I.) Inc. and its subsidiaries and affiliates (collectively, “Keylink”). Keylink is a 5% joint venture partner in our Shanghai manufacturing facilities. In addition, we conduct business with a related party company, Eris Technology Corporation (“Eris”). We owned over 30% of Eris’s outstanding Common Stock as of December 31, 2011.

RISKS RELATED TO OUR BUSINESS
The success of our business depends on the strength of the global economy and the stability of the financial markets, and any weaknesses in these areas may have a material adverse effect on our revenues, results of operations and financial condition.
Weaknesses in the global economy and financial markets can lead to lower consumer discretionary spending and demand for items that incorporate our products in the consumer electronics, computing, industrial, communications and the automotive sectors. A decline in end-user demand can affect 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, operating results and financial condition could be negatively affected by such actions.
During times of difficult market conditions, our fixed costs combined with lower revenues and lower profit margins may have a negative impact on our business, results of operations and financial condition.
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, we could be faced with a decline in the utilization rates of our manufacturing facilities due to decreases in product demand. During such periods, our manufacturing facilities do not operate at full capacity and the costs associated with this excess capacity are expensed immediately and not capitalized into inventory. This was the case at the end of 2008 and beginning of 2009 when our utilization rates declined to abnormally low production levels, which resulted in lower gross margins. The market conditions in the future may adversely affect our utilization rates and consequently our future gross margins, and this, in turn, could have a material negative impact on our business, results of operations and financial condition.
Downturns in the highly cyclical semiconductor industry and/or changes in end-market demand could adversely affect our results of operations 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 end-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, which may harm our results of operations and financial condition.
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 and financial condition 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, computing, communications, industrial and automotive sectors. These end-user markets also tend to be cyclical and may also experience changes in demand that could adversely affect our results of operations and financial condition.
The semiconductor business is highly competitive, and increased competition may harm our business, results of operations and financial condition.
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

Table of Contents
Semiconductor Corporation, Infineon Technologies A.G., International Rectifier Corporation, NXP Semiconductors N.V., ON Semiconductor Corporation, 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 business, results of operations and financial condition.
We receive a portion of our net sales from three customers, which all are related parties. In addition, two of these customers are large external suppliers. The loss of these customers or suppliers could harm our business, results of operations and financial condition.
In 2011, 2010 and 2009, LSC, our largest stockholder, accounted for less than 1%, 1% and 2%, 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 5%, 7% and 6%, respectively, of our net sales, in 2011, 2010 and 2009.
In 2011, 2010 and 2009, we subcontracted a portion of our manufacturing to Eris Technology Corporation (“Eris”), a publicly traded company listed as an Emerging Stock on the Taiwan OTC Exchange (TWO) that provides design, manufacturing and after-market services for diode products. We purchase finished goods, some sourced from our wafers and some not sourced from our wafers. Eris provides us with discrete semiconductor products for subsequent sale by us, which represented approximately 2%, 3% and 3%, respectively, of our net sales, in 2011, 2010 and 2009.
In addition, in 2011, 2010 and 2009, we sold products to companies owned by Keylink, totaling 2%, 3% and 3%, respectively. Also for 2011, 2010 and 2009, 1%, 2% and 1%, respectively, of our net sales were from semiconductor products purchased from companies owned by Keylink.
The loss of LSC, Keylink or Eris as either a customer or a supplier, or any significant reductions in either the amount of products LSC, Keklink and/or Eris supplies to us, or the volume of orders LSC, Keylink or Eris places with us, could materially harm our business, results of operations and financial condition.
Delays in initiation of production at facilities due to implementing new production techniques or resolving problems associated with technical equipment malfunctions could adversely affect our manufacturing efficiencies, results of operations and financial condition.
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, bringing 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 near Kansas City, Missouri, and near Manchester, United Kingdom (“U.K.”), while our manufacturing facilities in Shanghai, China and Neuhaus, Germany, perform packaging, assembly and test functions and our two joint venture facilities in Chengdu, China for surface mount component production, assembly and test functions. Any disruption of operations at these facilities could have a material adverse effect on our manufacturing efficiencies, results of operations and financial condition.
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 a decrease in average selling prices (“ASP”) for our products of 10% in 2009, an increase of 5% in 2010 and a decrease of 2% in 2011. At times, we may be required to sell our products at ASP below our manufacturing costs or purchase prices 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, which could adversely affect our revenues, results of operations and financial condition.
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 product, changes in the product’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 adversely affect our revenues, results of operations and financial condition.
Our customer orders are subject to cancellation or modification usually with no penalty. High volumes of order cancellation or reduction in quantities ordered could adversely affect our revenues, 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 purchase orders even though they may ultimately be cancelled. If a significant number of purchase 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 revenues, results of operations and financial condition may suffer.
Production at our manufacturing facilities could be disrupted for a variety of reasons, including natural disasters and other extraordinary events, which could prevent us from producing enough of our products to maintain our sales and satisfy our customers’ demands and could adversely affect our results of operations and financial condition.
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, floods, hurricanes, typhoons, droughts, tsunamis, volcanoes, earthquakes, disease or other similar natural disasters, unplanned maintenance or other manufacturing problems, labor shortages, power outages or shortages, telecommunications failures, strikes, transportation interruption, government regulation, terrorism or other extraordinary events. Such disruptions may cause direct injury or damage to our employees and property and related internal controls with significant indirect consequences. 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 and financial condition.
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 would adversely affect our net sales, market share, results of operations and financial condition.
Our product range and new product development program are focused on discrete, logic 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 would adversely affect our net sales, market share, results of operations and financial condition.
We may be adversely affected by any disruption in our information technology systems, which could adversely affect our cash flows, results of operations and financial condition.
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 cash flows, results of operations and financial condition.
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 cash flows, results of operations and financial condition.
A significant portion of our operations operate on a single Enterprise Resource Planning (ERP) platform. To manage our international operations efficiently and effectively, we rely heavily on our 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 will 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 a material adverse effect on our cash flows, results of operations and financial condition.
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, reduction in our intellectual property rights and a negative impact on our business, results of operations and financial condition.
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 technology that is 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 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;	
 
-13-

Table of Contents
 	•	 	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 reputation with customers, results of operations and financial condition 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 reputation with customers, results of operations and financial condition.
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, which could adversely affect our ability to compete, results of operations and financial condition.
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/test 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 United States (“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 facilities, 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, results of operations and financial condition 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, which could adversely affect our business, results of operations and financial condition.
A significant part of our growth strategy involves acquiring companies with complementary product lines, customers or other capabilities. For example, (i) in 2000, we acquired FabTech, Inc., a wafer fabrication company, in order to have our own wafer manufacturing capabilities, (ii) in 2006, we acquired Anachip Corp. as an entry into the analog market, (iii) in 2006, we acquired the net operating assets of APD Semiconductor, Inc. and (iv) in 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, results of operations and financial condition. 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.	
We are subject to many environmental laws and regulations that could result in significant expenses and could adversely affect our business, results of operations and financial condition.
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 manufacturing our products throughout the world. Some of these regulations in the U.S. 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, results of operations and financial condition. 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, warranty claims and product liability claims may be asserted against us, which may harm our business, reputation with our customers, results of operations and financial condition.
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 29 billion, 28 billion and 21 billion individual semiconductor devices in years ending December 31, 2011, 2010 and 2009, respectively, to customers around the world, and in the ordinary course of our business, we receive warranty claims and product liability 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 liability insurance, we may not have sufficient insurance coverage, and we may not have sufficient resources, to satisfy all possible warranty claims and 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, reputation, results of operations and financial condition.

We may fail to attract or retain the qualified technical, sales, marketing, finance and management personnel required to operate our business successfully, which could adversely affect on our business, results of operations and financial condition.
Our future success depends, in part, upon our ability to attract and retain highly qualified technical, sales, marketing, finance 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, finance 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 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 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, results of operations and financial condition could be materially and adversely affected.
We may not be able to maintain our growth or achieve future growth, and any such growth may place a strain on our management and on our systems and resources, which could adversely affect our business, results of operations and financial condition.
Our ability to successfully grow our business within the semiconductor industry 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, which could adversely affect our business, results of operations and financial condition.
Obsolete inventories as a result of changes in demand for our products and change in life cycles of our products could adversely affect our business, results of operations and financial condition.
The life cycles of some of our products depend heavily upon the life cycles of the end-products into which our products are designed. 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. 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 adverse economic conditions; therefore, some of our product inventory may become obsolete and, thus, adversely affect our business, results of operations and financial condition.
If OEMs do not design our products into their applications, 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 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 wins 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, which could adversely affect our business, results of operations and financial condition.
We have credit facilities with financial institutions in the U.S., 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. An increase of 1% in interest rates on our credit facilities would increase our annual interest rate expense by less than $1 million.

We may have a significant amount of debt with various financial institutions worldwide. Any indebtedness could adversely affect our business, results of operations, financial condition and our ability to meet our payment obligations under such debt.
We may have a significant amount of debt and substantial debt service requirements in our borrowings, including our credit facilities with various financial institutions worldwide. On February 1, 2012, we obtained a three-year term loan in the amount of $40 million with Bank of America, N.A. As of December 31, 2011, we had an aggregate outstanding debt of $8 million and $3 million used for import and export guarantees under our credit facilities with various financial institutions worldwide. In addition, an aggregate amount of $56 million is available for future borrowings under our credit facilities in the U.S., Asia and Europe, and we are permitted under the terms of our debt agreements under various credit facilities to incur substantial additional debt.
A significant amount 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 our 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, results of operations, financial condition and our ability to meet our payment obligations under our debt.
Restrictions in our credit facilities may limit our business and financial activities, including our ability to obtain additional capital in the future.
On November 25, 2009, we entered into a Credit Agreement with Bank of America, N.A. as subsequently modified, which provides for a $10 million revolving credit facility, a $10 million uncommitted facility and a three-year $40 million term loan for our general corporate purposes.
This Credit Agreement contains covenants imposing various restrictions on our business and financial activities. These restrictions may affect our ability to operate our business and undertake certain financial activities and may limit our ability to take advantage of potential business or financial opportunities as they arise. The restrictions these covenants place on us include limitations on our ability to incur liens, incur indebtedness, make investments, dissolve or merge or consolidate with or into another entity, dispose of certain property, make restricted payments, issue or sell equity interests, engage in other different material lines of business, conduct related party transactions, enter into certain burdensome contractual obligations and use proceeds from any credit facility to purchase or carry margin stock or to extend credit to others for the same purpose. The Credit Agreement also requires us to meet certain financial ratios, including a fixed charge coverage ratio and a quick ratio.
Our ability to comply with the Credit Agreement may be affected by events beyond our control, including prevailing economic, financial and industry conditions, and are subject to the risks stated in this section of the Annual Report. The breach of any of these covenants or restrictions could result in a default under the Credit Agreement. An event of default under the Credit Agreement would permit Bank of America, N.A. to declare all amounts owed under such Credit Agreement to be immediately due and payable in full. Acceleration of our other indebtedness may cause us to be unable to make interest payments for the credit facilities and repay the principal amount of the credit facilities. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations –  Debt instruments”  in Part II, Item 7 of this Annual Report for additional information.
The value of our benefit plan assets and liabilities is based on estimates and assumptions, which may prove inaccurate and the actual amount of expenses recorded in the consolidated financial statements could differ materially from the assumptions used.
Certain of our employees in the U.K., Germany and Taiwan participate in Company sponsored defined benefit plans. The defined benefit plan in the U.K. 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. In accounting for these plans, we are required 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 our 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 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 financial condition.
The asset value of our defined benefit plan (the “plan”) has been volatile over the past year 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 us to utilize certain actuarial assumptions for the plan’s fair value determination.
As of December 31, 2011, the benefit obligation of the plan was approximately $110 million and the total assets in such plan were approximately $96 million. Therefore, the plan was underfunded by approximately $14 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.
Any fluctuations in the United Kingdom’s equity markets and bond markets or 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 financial condition.
In 2009, we adopted a payment scheme with the trustees of the plan in which we paid approximately £1 million GBP every year from 2009 through 2011. We and the trustees are in discussions to extend the payment scheme through 2019.
In 2010, we established a joint venture to build a semiconductor facility in Chengdu, China. We are required to contribute at least $48 million to the joint venture during the first three years with additional contributions thereafter, as well as a substantial amount of time and resources to establish and operate the joint venture. Any failure to meet any such requirements, delays or unforeseen circumstances may cause us to incur penalties or require us to contribute additional expenses or resources and, as a result, could have an adverse effect on our operating efficiencies, results of operations and financial conditions.
Effective as of September 10, 2010, we entered into an Investment Cooperation Agreement and a Supplementary Agreement to the Investment Cooperation Agreement (collectively, the “CDHT Agreements”) with the Management Committee of the Chengdu Hi-Tech Industrial Development Zone (“CDHT”) to build a facility in Chengdu, China, with a Chinese local partner, for surface mount component production, assembly and test functions. The CDHT Agreements require us to contribute substantial capital to the joint venture, including at least $48 million in installments during the first three years, as well as time and resources to establish and operate the joint venture. We must obtain various licenses, permissions, certifications and approvals, from time to time, related to the joint venture’s business operations. Any failure to meet any such requirements, delays or unforeseen circumstances may cause us to incur penalties, or require us to cease of operations, or contribute additional expenses and/or resources and as a result, could have a material adverse effect on our operating efficiencies, results of operations and financial conditions. As of December 31, 2011, we have invested approximately $25 million of which $18 million were for capital expenditures.
Certain of our customers and suppliers require us to comply with their codes of conducts, which may include certain restrictions that may substantially increase the cost of our business as well as have an adverse effect on our operating efficiencies, results of operations and financial condition.
Certain of our customers and suppliers require us to agree to comply with the Electronic Industry Code of Conduct (“EICC”) or their own codes of conduct, which may include detailed provisions on labor, human rights, health and safety, environment, corporate ethics and management systems. Certain of these provisions are not requirements under the laws of the countries in which we operate and may be burdensome to comply with on a regular basis. Moreover, new provisions may be added or material changes may be made to any these codes of conduct, and we will have to promptly implement such new provisions or changes, which may substantially further increase the cost of our business, be burdensome to implement and adversely affect our operational efficiencies and results of operations. If we violate any such codes of conduct, we may lose further business with the customer or supplier and, in addition, we may be subject to fines from the customer or supplier. While we believe that we are currently in compliance with our customers and suppliers’ codes of conduct, there can be no assurance that, from time to time, if any one of our customers and suppliers audits our compliance with such code of conduct, we would be found to be in full compliance. A loss of business from these customers or suppliers could have a material adverse effect on our business, results of operations and financial conditions.

There are risks associated with previous and future acquisitions. We may ultimately not be successful in overcoming these risks or any other problems encountered in connection with acquisitions.
The risks commonly encountered in acquisitions of companies include, among other things, higher than anticipated acquisition costs and expenses, the difficulty and expense in integrating the operations and personnel of the companies, the difficulty of bringing standards, procedures and controls into conformance with our operations, the ability to coordinate our new products and process development, the ability to hire additional management and other critical personnel, the ability to increase the scope, geographic diversity and complexity of our operations, difficulties in consolidating facilities and transferring processes and know-how, difficulties in reducing costs, prolonged diversion of our management’s attention from the management of our business, the ability to clearly define our present and future strategies, the loss of key employees and customers as a result of changes in management and any geographic distances may make integration slower and more challenging. We may ultimately not be successful in overcoming these risks or any other problems encountered in connection with acquisitions.
In addition, any 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.
If we fail to maintain an effective system of internal controls or discover material weaknesses in our internal control 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.
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 results of operations and financial condition.
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 China and Germany and our wafer fabrication facilities in Missouri and the U.K., 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 of operations and financial condition.
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 2011, 2010 and 2009, net sales to customers outside the U.S. represented 83%, 78% and 83%, 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 U.S. 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;	
 
-19-

Table of Contents
 	•	 	restrictions on the transfer of funds from foreign subsidiaries to the U.S.;	
 
 	•	 	the possibility of international conflict, particularly between or among China, the U.K., Germany, Taiwan and the U.S.;	
 
 	•	 	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, the United Kingdom, Germany, Hong Kong and Taiwan and, as a result, will be subject to risks inherent in doing business in those jurisdictions, which may adversely affect our financial performance and results of operations.
We have a significant portion of our assets in mainland China, United Kingdom, Germany, Hong Kong and Taiwan. Our ability to operate in these countries 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 and financial performance 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, the United Kingdom, Germany, Hong Kong, Taiwan and the U.S. 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 U.S. could have an adverse impact upon our ability to transact business in these jurisdictions and to generate profits.
A slowdown in the Chinese economy could limit the growth in demand for electronic devices containing our products, which would have a material adverse effect on our business, results of operations and prospects.
We believe that an increase in demand in China for electronic devices that include our products will be an important factor in our future growth. Although the Chinese economy has grown significantly in recent years, there can be no assurance that such growth will continue. Any weakness in the Chinese economy could result in a decrease in demand for electronic devices containing our products and, thereby, materially and adversely affect our business, results of operations and prospects.
Economic regulation in China could materially and adversely affect our business, results of operations and prospects.
We have a significant portion of our manufacturing capacity in China. In addition, in 2011 33% of our total sales were billed to customers in China. In recent years, the Chinese economy has experienced periods of rapid expansion and wide fluctuations in the rate of inflation. In response to these factors, the Chinese government has, from time to time, adopted measures to regulate growth and contain inflation, including measures designed to restrict credit or control prices. Such actions in the future could increase the cost of doing business in China or decrease the demand for our products in China and, thereby, have a material adverse effect on our business, results of operations and prospects.
We could be adversely affected by violations of the United States’ Foreign Corrupt Practices Act, the United Kingdom’s Bribery Act 2010 and similar worldwide anti-bribery laws.
The United States’ Foreign Corrupt Practices Act (“FCPA”), the United Kingdom’s Bribery Act 2010 (the “UK Bribery Act”) 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, the UK Bribery Act and related anti-bribery laws. We have established 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, the UK Bribery Act and other anti-bribery law violations (either due to our own acts or inadvertence, or due to the acts or inadvertence of others), we could incur 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, principally the Chinese Yuan, the Taiwanese dollar, the Euro and the British Pound Sterling and, to a lesser extent, the Japanese Yen and the Hong Kong dollar. Our income and expenses are based on a mix of currencies and a decline in one currency relative to the other currencies could adversely affect our results of operations. Furthermore, our results of operations are reported in U.S. dollars, which is our reporting currency. In the event the U.S. dollar weakens against a foreign currency, we will experience a currency transaction loss, which could adversely affect our results of operations. Also, fluctuations in foreign currency exchange rates may have an adverse impact and be increasingly influential to our overall sales, profits and results of operations as amounts that are measured in foreign currency are translated back to U.S. dollars for reporting purposes. 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, especially as the portion of our sales attributable to Europe increases. 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.
China is experiencing rapid social, political and economic change, which has increased labor costs and other related costs that could make doing business in China less advantageous than in prior years. Increased labor costs in China could adversely affect our business, results of operations and financial condition.
Historically, labor in China has been readily available at a lower cost compared to other countries, and any increase in labor cost in China has been consistent with the projected annual increase in the inflation index and the amount of past labor cost increases. However, because China is experiencing rapid social, political and economic change, there can be no assurance that labor will continue to be available in China at costs consistent with historical levels. Any future increase in labor cost in China is likely to be higher than historical and projected amounts and may occur multiple times in any given year. As a result of experiencing such rapid social, political and economic change, China is also likely to enact new, and/or revise its existing, labor laws and regulations on employee compensation and benefits. These changes in Chinese labor laws and regulations will likely to have an adverse effect on product manufacturing costs in China. Furthermore, if China workers go on strike to demand higher wages, our operations could be disrupted. Many of our suppliers are currently dealing with labor shortages in China, which may result in future supply delays and disruptions and may drive a substantial increase in their labor costs that is likely to be shared by us in the form of price increases to us. New or revised government labor laws or regulations, strikes or labor shortages could cause our product costs to rise and/or could cause manufacturing partners on whom we rely to exit the business. These events could have a material adverse impact on our product availability and quality, which would affect our business, results of operations and financial condition.
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 received preferential tax treatment. In addition, in conjunction with the acquisition of Anachip Corp., 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 United States income taxes, thus reducing our net income.
With the establishment of our holding companies in 2007 and 2011, we intend to permanently reinvest overseas all earnings from foreign subsidiaries. Although we intend to permanently reinvest overseas all earnings, certain unusual circumstances may require us to repatriate funds. This was the case during the first quarter of 2009, in which we repatriated approximately $29 million of accumulated earnings from one of our Chinese subsidiaries, resulting in additional non-cash U.S. federal and state income tax expense of approximately $5 million.
As of December 31, 2011, accumulated and undistributed earnings of our subsidiaries in China were approximately $212 million, which we consider as a permanent investment.
As of December 31, 2011, we have undistributed earnings from non-U.S. operations of approximately $265 million (including approximately $33 million of restricted earnings, which are not available for dividends). Additional U.S. federal and state income taxes of approximately $45 million would be required should such earnings be repatriated to the U.S.
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:
 
 	•	 	strength of the global economy and the stability of the financial markets;	
 
 	•	 	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 the demand for our customers’ products;	
 
 	•	 	our ability to develop new process technologies and achieve volume production at our fabrication facilities;	
 
 	•	 	changes in manufacturing yields;	
 
 	•	 	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 adversely 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 27% of our outstanding Common Stock, including options to purchase shares of our Common Stock that are exercisable within 60 days of December 31, 2011. 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 18% (approximately 8 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. Raymond Soong, the Chairman of the Board of Directors, is the Chairman of LSC, and is the Chairman of Lite-On Technology Corporation, a significant shareholder of LSC. C.H. Chen, our former President and Chief Executive Officer and currently the Vice Chairman of the Board of Directors, is also Vice Chairman of LSC and Lite-On Technology Corporation. Dr. Keh-Shew Lu, our President and Chief Executive Officer and a member of our Board of Directors, is a member of the Board of Directors of Lite-On Technology Corporation. L.P. Hsu, a member of the Board of Directors since 2007, serves as a consultant to Lite-On Technology Corporation. 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

Table of Contents
with decisions involving the Common Stock owned by LSC, or under the other agreements we may enter into with LSC. In 2011, 2010 and 2009, LSC accounted for less than 1%, 1% and 2%, respectively, of our net sales. Also, in 2011, 2010 and 2009, approximately 5%, 7% and 6%, respectively, of our net sales were from products manufactured by LSC, making LSC our largest external supplier of discrete semiconductor products.
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 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.
Non-cash tender offers, debt equity swaps or equity exchanges to consummate our business activities are likely to have the effect of diluting the ownership interest of existing stockholders, including qualified stockholders who receive shares of our Common Stock in such business activities.
We, from time to time, may utilize non-cash tender offers, debt equity swaps or equity exchanges in accordance with the guidance and rules promulgated by the United States Securities and Exchange Commission to consummate our business activities. Such means to consummate our business activities will likely involve issuance of our Common Stock in large quantities and will subsequently dilute the ownership interest of existing stockholders, including stockholders who previously received shares of our Common Stock in such transactions. Any sales in the public market of the newly issued Common Stock could adversely affect prevailing market prices of our Common Stock. In addition, utilizing non-cash tender offers, debt equity swaps or equity exchanges may encourage short selling because such utilization could depress the price of our Common Stock.
Anti-takeover effects of certain provisions of Delaware law and our Certificate of Incorporation and Bylaws, may hinder a take-over attempt.
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 may deter a take-over attempt.
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 by 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 may deter a take-over attempt.
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.

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. We have never repurchased our shares of Common Stock.

Item 7.	Management’s Discussion and Analysis of Financial Condition and Results of Operations	
The following section discusses management’s 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. We base these statements on our beliefs as well as assumptions we made using information currently available to us. Such statements are subject to risks, uncertainties and assumptions, including those identified in Part I, Item 1A.”Risk Factors,” as well as other matters not yet known to us or not currently considered material by us.

Business Outlook
For 2012, we intend to enhance our position as a leading global manufacturer and supplier of high-quality semiconductor products, and to continue expanding key product lines, such as power management, super barrier rectifier (SBR ® ), MOSFETs and logic products, while continuing to develop innovative packaging technology capability. We expect our business to continue to benefit from increasing demand in China, as we consider the China market a major growth driver for our business. We expect revenue for the first quarter of 2012 to be better than the normal seasonal pattern, although the first quarter is typically a seasonally down quarter, due to improved distributor order rates in North America and Europe as well as ramping of new projects for our products used in smartphones and tablets.
The success of our business depends, among other factors, on the strength of the global economy and the stability of the financial markets, 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 global economy and the equity and credit markets as we continue to execute on the strategy that has proven successful for us over the years. See “Risk Factors— The success of our business depends on the strength of the global economy and the stability of the financial markets, and any weaknesses in these areas may have a material adverse effect on our revenues, results of operations and financial condition.”  in Part I, Item 1A of this Annual Report for additional information.
Overview of 2011
During the first quarter of 2011, net sales were stronger than typical first quarter seasonal patterns, assisted by increased demand in tablets, notebooks, smartphones and LED TV’s. We saw strong demand in Europe and Asia, while North America revenue declined sequentially from fourth quarter of 2010. In addition, the first quarter of 2011 was impacted by reduced unit output from our packaging facilities due to lower equipment utilization as a result of China labor shortages, and gross margin reflected reduced fixed cost coverage caused by the lower unit output. Although we experienced lower unit output during the first quarter, we were able to ship from finished goods inventory and reduced our contract assembly commitments, which allowed us to achieve sequential revenue growth in our core business.

During the second quarter of 2011, we continued to focus on design wins, new products and customer expansion. During May, we started to see a slowdown in the global markets, in particular the consumer and computing space. This weakness accelerated in the last several weeks of the second quarter, affecting several of our customers that build product for the U.S. and European markets. Gross margin in the second quarter was also impacted by the softening demand, which caused us to change our mix to lower margin commodity products to support revenue. In addition, there was a slower than expected ramp in productivity due to the training requirements for replacing operators as a result of the China labor shortages, which was completed in the third quarter.
During the third quarter of 2011, we continued to see broad weakness across global markets that began in May and accelerated throughout the third quarter. Despite this softness, we were able to execute our strategy of gaining market share by shifting our product mix to lower margin products to best utilize our installed capacity, and we grew our nine month revenue 10% over the prior year period. We continued to drive manufacturing productivity improvements at our China packaging facilities to maximize the utilization of our operators and equipment. We used excess capacity to build finished goods inventory in preparation for a three day shut-down for the China National Holiday, which occurred during the first week in October. In response to these market conditions, during the third quarter, we implemented cost reduction actions that included the delay of capital investments, hiring freezes, a reduction in factory overtime, as well as temporary reductions on travel.
During the fourth quarter of 2011, the broad weakness that began in May and throughout the third quarter, continued to impact all of our market segments. However, past design win momentum and new product initiatives enabled further market share gains. Although productivity and manufacturing efficiencies in our Shanghai facility recovered to prior levels, gross margin continued to be negatively impacted by the effects of the market softness including increased pricing pressure, continued sales of lower margin commodity products and less than maximum utilization of manufacturing capacity, despite the increase in our finished goods inventory in advance of the Chinese New Year.
Factors Relevant to Our Results of Operations
In 2011, the following factors affected, and, we believe, will continue to affect, our results of operations:
 
 	•	 	We have experienced pressure from our customers and competitors to reduce the selling price for our standard products, and we expect future improvements in net income to result primarily from increases in sales volume and improvements in product mix as well as manufacturing cost reductions in order to offset any reduced average selling prices (“ASP”) 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 for additional information.	
 
 	•	 	For the years ended December 31, 2011, 2010 and 2009, our original equipment manufacturers (“OEM”) and electronic manufacturing services (“EMS”) customers together accounted for 47%, 46% and 53% of net sales, respectively, while our global network of distributors accounted for 53%, 54% and 47% of net sales, respectively.	
 
 	•	 	Our gross profit margin was 30% in 2011, compared to 37% in 2010 and 28% in 2009. Our gross profit margin decreased in 2011 primarily due to increased pricing pressure and the decline in business in North America and Europe, where our gross margins are typically higher than Asia. Our target rate is 35% as we strive to improve our gross margins in support of our profitable growth strategy. Future gross profit margins will depend primarily on our product mix, manufacturing cost savings, and the demand for our products.	
 
 	•	 	For 2011, the percentage of our net sales derived from our Asian subsidiaries was 75%, compared to 73% in 2010 and 77% in 2009. In addition, Europe accounted for approximately 13%, 12% and 10% of our net sales in 2011, 2010 and 2009, respectively. At the end of the 2011, business in North America and Europe was weak and therefore, when they recover, we expect our net sales to the Asian market to decrease from fourth quarter levels as a percentage of our total net sales.	
 
 	•	 	As of December 31, 2011, we had invested approximately $348 million in our manufacturing facilities in China. During 2011, we invested approximately $64 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 2011, our capital expenditures, excluding capital expenditures related to our joint venture in Chengdu, China, were approximately 10% of our net sales, which is at the lower end of our historical 10% to 12% of net sales model as we delayed capital investments in the third and fourth quarters in response to market conditions. For 2012, we expect capital expenditures, excluding Chengdu building expenditures, to be in their normal range of 10% to 12% of net sales.	
 
 	•	 	Our investment in research and development remained relatively the same at $27 million in 2010 and 2011. In 2011, research and development expenses were approximately 4% of net sales.

Year 2011 Compared to Year 2010

 	  	2011	 	  	2010	 	
Net sales	  	$	635,251	 	  	$	612,886	 	
Net sales for 2011 increased $22 million to $635 million from $613 million for 2010. The 4% increase in net sales represented an approximately 6% increase in units sold and a 2% decrease in ASP. The revenue increase for 2011 was attributable to increase in demand for our products in Asia and Europe, offset in part by a decline in North America.

Cost of goods sold increased $54 million, or 14%, for 2011 to $442 million, compared to $388 million for 2010. As a percent of sales, cost of goods sold increased from 63% for 2010 to 70% for 2011. Our average unit cost (“AUP”) increased approximately 7%. The increase in cost of goods sold as a percentage of net sales and the increase in AUP was due to lower capacity utilization in our manufacturing operations.
Gross profit for 2011 decreased 14% to $194 million from $225 million for 2010. Gross profit as a percentage of net sales was 30% for 2011, compared to 37% for 2010. The decreased gross margin was primarily due to a weak pricing environment and a shift in product mix to lower margin products in an effort to maintain capacity utilization at our wafer fabrication facilities and Shanghai packaging facilities.

Gross profit	  	$	224,869	  	 	$	121,207	  	
Gross profit margin	  	 	37	% 	 	 	28	% 	
Cost of goods sold increased $75 million, or 24%, for 2010 to $388 million, compared to $313 million for 2009. As a percent of sales, cost of goods sold decreased from 72% for 2009 to 63% for 2010. Our average unit cost (“AUP”) decreased approximately 8%. The decrease in cost of goods sold as a percentage of net sales and the decrease in AUP was due to higher capacity utilization in our manufacturing operations.
Gross profit for 2010 increased 86% to $225 million from $121 million for 2009. Gross profit as a percentage of net sales was 37% for 2010, compared to 28% for 2009. The increased gross margin was primarily due to higher capacity utilization of our manufacturing and wafer fabrication facilities, increased operating efficiencies and improved product mix.

SG&A for 2010 increased $18 million, or 26%, to $89 million, compared to $70 million for 2009, due primarily to higher sales commissions related to increased sales, as well as to higher employee related costs including incentives and higher general operating costs. SG&A, as a percentage of net sales, was 15% in 2010, compared to 16% in 2009.

Income tax provision	  	$	17,839	  	  	$	1,302	  	
We recognized income tax expense of $18 million for 2010, resulting in an effective tax rate of 18%, as compared to 12% for 2009. Our effective tax rate compared with the same period last year was higher as it was impacted by additional income in higher-taxed jurisdictions. This was partially offset by provision-to-return adjustments and the non-cash tax benefit from reversing valuation allowances on deferred tax assets from U.S. and U.K. loss carryforwards. In 2009, the effective tax rate was impacted by the non-cash income tax expense of approximately $8 million associated with repatriating earnings of foreign subsidiaries to the U.S. parent. This was partially offset by provision-to-return adjustments recorded in 2009.

Financial Condition
Liquidity and Capital Resources
Our primary sources of liquidity are cash and cash equivalents, funds from operations and borrowings under our credit facilities. As of December 31, 2011, we had a U.S. credit agreement for a $10 million revolving credit facility with $8 million outstanding borrowings, a $10 million uncommitted facility with no outstanding borrowings and foreign credit facilities giving us total borrowing capacity of approximately $47 million of which approximately $3 million had been used for import and export guarantees. Our primary liquidity requirements have been to meet our inventory and capital expenditure needs and to fund on-going operations. For 2011, 2010 and 2009, our working capital was $317 million, $289 million, and $354 million, respectively. Our working capital increased in 2011 mainly due to an increase in inventory and prepaid expenses and a decrease in accounts payable, accrued liabilities and income tax payable, partially offset by an increase in lines of credit. Our working capital decreased in 2010 mainly due to our Notes being reclassified from long-term debt to current liabilities, partially offset by an increase in cash, accounts receivables and inventories. 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.
On February 1, 2012, we amended our credit agreement with Bank of America, N.A. (“Bank of America”) to provide for a term loan in the amount of $40 million, which matures on January 17, 2015. The proceeds may be used for general corporate purposes, potential acquisitions, to finance temporary cash shortages, capital expenditures and to pay fees and expenses in connection therewith. It bears interest at a rate per annum equal to the Eurocurrency Rate (as defined) plus 1.25% per annum. In addition, it is not a revolving credit facility and any amount repaid may not be reborrowed. For a description of this term loan and our amended credit agreement with Bank of America, see “ Debt instruments” below.
In October 2006, we issued and sold our Notes, which paid 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. On September 30, 2011, we repurchased Notes in an aggregate principal amount of approximately $134 million plus accrued and unpaid interest. On December 1, 2011, we repurchased the remaining outstanding Notes in an aggregate principal amount of less than $1 million plus accrued and unpaid interest. As of December 31, 2010, all Notes have been redeemed.
In 2011, 2010 and 2009, our capital expenditures were $83 million, $87 million and $26 million, respectively , which includes $18 million of capital expenditures related to the investment agreement with the Management Committee of the Chengdu Hi-Tech Industrial Development Zone (the “CDHT”) for 2011. 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 office buildings in the U.S. and China. Capital expenditures, excluding capital expenditures related to the investment agreement, for 2011 were approximately 10% of our net sales, which is at the lower end of our historical 10% to 12% of net sales model as we delayed capital investments in the third and fourth quarters in response to market conditions.
During 2010, we announced an investment agreement with the Management Committee of the CDHT. Under this agreement, we have agreed to form a joint venture with a Chinese partner, Chengdu Ya Guang Electronic Company Limited, to establish a semiconductor manufacturing facility for surface mount component production, assembly and test in Chengdu, China. We initially will own at least 95% of the joint venture. The manufacturing facility will be developed in phases over a ten year period, and we expect to contribute at least $48 million to the joint venture in installments during the first three years. The CDHT will grant the joint venture a fifty year land lease, provides temporary facilities for up to three years at a subsidized rent while the joint venture builds the manufacturing facility and provides corporate and employee tax incentives, tax refunds, subsidies and other financial support to the joint venture and its qualified employees. If the joint venture fails to achieve specified levels of investment, the investment agreement allows for a renegotiation as well as the option to repay a portion of such financial support. This is a long-term, multi-year project that will provide us additional capacity as needed. As of December 31, 2011, we have invested approximately $25 million of which $18 million were for capital expenditures.

Discussion of Cash Flows
Cash and cash equivalents have increased from $242 million at December 31, 2009, to $271 million at December 31, 2010, then decreased to $130 million at December 31, 2011. The increase from 2009 to 2010 was primarily due to net cash provided by operating activities. The decrease during 2011 was primarily due to net cash used in financing activities for the retirement of our Notes.

Operating Activities
Net cash provided by operating activities during 2011 was $62 million, resulting primarily from $54 million of net income in the period, $61 million of depreciation and amortization and $14 million from non-cash share-based compensation, partially offset by a $20 million increase in inventory, a $15 million increase in excess tax benefit from share-based compensation and a $22 million increase in deferred income taxes. Deferred income taxes relate to the retirement of our Notes and are recorded in cash flows from operations while other items related to retirement of the Notes was included in cash flows from financing in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”). Net cash provided by operating activities was $118 million for 2010 and $66 million for 2009.
Net cash provided by operating activities decreased by $56 million from 2010 to 2011. This decrease resulted primarily from a decrease in net income (from $80 million in 2010 to $54 million in 2011) and increase in tax related items.
Net cash provided by operating activities increased by $53 million from 2009 to 2010. This increase resulted primarily from an increase in net income (from $10 million in 2009 to $80 million in 2010), partially offset by a $30 million increase in inventory.
Investing Activities
Net cash used by investing activities for 2011 was $98 million, resulting primarily from $14 million in purchases of securities and $81 million in capital expenditures.
Net cash provided by investing activities for 2010 was $210 million, resulting primarily from $297 million in proceeds from sale of auction rate securities, offset by $89 million in capital expenditures.
Net cash provided by investing activities for 2009 was $2 million, resulting primarily from $24 million in proceeds from sale of securities, offset by $23 million in capital expenditures.
Financing Activities
Net cash used by financing activities for 2011 was $108 million, resulting primarily from $135 million in repayments short-term debt, which was mainly the retirement of our Notes.
Net cash used by financing activities for 2010 was $295 million, resulting primarily from $303 million in repayments of lines of credit and short-term debt, which was mainly the repayment of our “no net cost” loan.

Table of Contents
Net cash provided by financing activities for 2009 was $68 million, resulting primarily from the proceeds of lines of credit and short-term debt of $127 million, mainly from the “no net cost” loan, partially offset by $45 million in repayments of short-term debt and $13 million in repayments of long-term debt.
Debt instruments
On November 25, 2009 we entered into a credit agreement with Bank of America as modified by a certain letter dated as of March 31, 2010, the First Amendment to Credit Agreement dated as of July 16, 2010, the Second Amendment to Credit Agreement dated as of November 24, 2010, the Third Amendment to Credit Agreement dated as of February 4, 2011, the Fourth Amendment to Credit Agreement dated as of November 23, 2011 and the Fifth Amendment to Credit Agreement dated as of February 1, 2012 (collectively the “Credit Agreement”). The Credit Agreement provides for a $10 million revolving credit facility (the “Revolver”) and a $10 million uncommitted facility (the “Uncommitted Facility”).
The Fifth Amendment added an additional borrower, Diodes International B.V. (the “BV Entity”), to the Credit Agreement and provides for an additional term loan in the amount of $40 million (the “Term Loan”). The Term Loan matures on January 17, 2015. The proceeds may be used for general corporate purposes, potential acquisitions, to finance temporary cash shortages, capital expenditures and to pay fees and expenses in connection therewith. The Term Loan will bear interest at a rate per annum equal to the Eurocurrency Rate (as defined) plus 1.25% per annum. On February 1, 2012, the BV Entity drew down the full $40 million of the Term Loan, which is not a revolving credit facility and any amount repaid may not be reborrowed.
The Revolver includes a $2 million sublimit for letters of credit. Both the Revolver and the Uncommitted Facility mature on January 17, 2013. The proceeds under the Revolver and the Uncommitted Facility may be used for general corporate purposes, to finance temporary cash shortages and to minimize taxes associated with moving cash between countries. As of December 31, 2011, there was $8 million outstanding under the Revolver or the Uncommitted Facility.
Under the Revolver, as amended by the Fifth Amendment, we may borrow through Base Rate Committed Loans in United States Dollars (“USD”), or through Eurocurrency Rate Committed Loans in USD, Euros or British Pounds Sterling. Base Rate Committed Loans bear interest on the outstanding principal amount from the applicable borrowing date at a rate per annum equal to the Federal Funds Rate plus one half of one percent (0.50%) per annum. Eurocurrency Rate Committed Loans allow for interest on the outstanding principal amount to be based on the LIBOR 1, 2 or 3 Month Fixed Rate plus three percent (2.5%) per annum.
Under the Uncommitted Facility, we may borrow only in USD, and each borrowing will bear interest on the outstanding principal amount from the applicable borrowing date at the rate per annum quoted to us by Bank of America and accepted by us prior to such borrowing. Each borrowing under the Uncommitted Facility and accrued and unpaid interest thereon, shall be due and payable, on the earlier of (a) the Maturity Date, or (b) a date set by Bank of America and accepted by us prior to such borrowing under the Uncommitted Facility.
We may prepay any borrowing under the Revolver or the Uncommitted Facility in full or in part at any time; however, we shall repay to Bank of America on the Maturity Date the aggregate principal amount of any borrowing under the Revolver or the Uncommitted Facility outstanding on such date.
As part of the Credit Agreement, we and each of our subsidiaries (including Diodes Zetex Limited) agreed to have Bank of America as our principal depository bank, including for the maintenance of business, operating and administrative deposit accounts.
Any borrowing and obligations under the Revolver or under the Uncommitted Facility is secured by accounts, chattel paper, deposit accounts and inventory, and all dividends, distributions, and income attributable to proceeds, products, additions to, substitutions, replacements and supporting obligations for, model conversions, and accessions of the foregoing, of us and of certain of our subsidiaries. Certain subsidiaries of ours also guaranty any borrowing and obligations and pledge their interests to Bank of America in certain subsidiary stock owned by such subsidiary guarantors. In addition, as amended by the Fifth Amendment, 65% of our interests in the BV Entity have been pledged as security for all obligations under the Credit Agreement.
The Credit Agreement contains, as amended by the Fifth Amendment, certain restrictive and financial covenants, including, but not limited to, us maintaining on a consolidated basis a Quick Ratio of not less than 1.50 to 1.0, and Interest Coverage Ratio to be at least 3.0 to 1.0 and a Funded Debt to EBITDA Ratio not to exceed 2.5 to 1.0.
As of December 31, 2011, our U.S., Asia and Europe subsidiaries have available lines of credit of up to an aggregate of approximately $67 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, 2011, there was $8 million outstanding on these lines of credit, and the interest rates ranged from 2.2% to 4.6%. See Note 10 of “Notes to Consolidated Financial Statements” of this Annual Report for additional information.

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.

(1)	See “Other Commitments” in Note 16 of “Notes to Consolidated Financial Statements” for additional information.	
Tax liabilities are not included in the above contractual obligations as we cannot make reasonable estimates of the amount and period in which those tax liabilities would be paid. See  “Accounting for income taxes”  below and Note 11 of “Notes to Consolidated Financial Statements” of this Annual Report for additional information.
Critical Accounting Policies and Estimates
The preparation of financial statements in conformity with U.S. 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
Revenue is recognized when there is persuasive evidence that an arrangement exists, when delivery has occurred, when the 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 product is shipped to the customers. Generally, we recognize revenue upon shipment to manufacturers (direct ship) as well as upon sales to distributors using the “sell in” model, which is when product is shipped to the distributors (point of purchase).
Certain customers have limited rights of return and/or are entitled to price adjustments on products held in their inventory or upon sale to their end customers. We reduce net sales in the period of sale for estimates of product returns, distributor price adjustments and other allowances. Our reserve estimates are based upon historical data as well as projections of sales, 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 net sales.
We record allowances/reserves for the following items: (i) ship and debit, which arise when we, from time to time based on market conditions, issue credit to certain distributors upon their shipments to their end customers, (ii) stock rotation, which are contractual obligations that permit certain distributors, twice a year, to return a portion of their inventory based on historical shipments to them in exchange for an equal and offsetting order, and (iii) price protection, which arise when market conditions cause average selling prices to decrease and we issue credit to certain distributors on their inventory.
 
-39-

Table of Contents
Ship and debit reserves are recorded as a reduction to net sales with a corresponding reduction to accounts receivable. Stock rotation reserves are recorded as a reduction to net sales with a corresponding reduction to cost of goods sold for the estimated cost of inventory that is expected to be returned. Price protection reserves are recorded as a reduction to net sales with a corresponding increase in accrued liabilities.
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 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. This analysis requires considerable judgment and is subject to change to reflect future events and changes in the tax laws.
A tax position is recognized as a benefit only if it is more likely than not that the tax position would be sustained based on its technical merits in a tax examination, using the presumption the tax authority has full knowledge of all relevant facts regarding the position. The amount recognized is the largest amount of tax benefit that is greater than 50% likely of being realized on ultimate settlement with the tax authority. For tax positions not meeting the more likely than not test, no tax benefit is recorded.
Goodwill and long-lived assets
Goodwill is tested for impairment on an annual basis, on October 1, and between annual tests if indicators of potential impairment exist. For 2011, we elected to early adopt Financial Accounting Standards Board (“FASB”) Accounting Standards Update (“ASU”) No. 2011-08,  Intangibles-Goodwill and Other (Topic 350): Testing Goodwill for Impairment . ASU No. 2011-08 simplified goodwill impairment testing by allowing us to first assess qualitatively whether it is necessary to perform step one of the two-step annual goodwill impairment test. We are required to perform step one and calculate the fair value of its reporting units only if we conclude that it is more likely than not that a reporting unit’s fair value is less than its carrying value (that is, a likelihood of more than 50 percent). The qualitative analysis, which we refer to as step zero, was performed and we considered all relevant factors specific to its reporting units. Some factors considered in step zero were macroeconomic conditions, industry and market considerations, cost factors, overall financial performance, events affecting a reporting unit and other relevant entity-specific events. Our conclusion of step zero was that goodwill is deemed to be not impaired and no further testing is required until the next annual test date (or sooner if conditions or events before that date raise concerns of potential impairment in the business).
For all years prior to 2011, 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. No impairment of goodwill has been identified during any of the periods presented.
Share-based compensation
We use the Black-Scholes-Merton model to determine the fair value of stock options 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. Restricted stock grants are measured based on the fair market value of the underlying stock on the date of grant.

Fair value measurements
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 at the measurement date. As such, fair value is a market-based measurement that should be determined based on the assumptions that market participants would use in pricing an assets or liability. Fair value is based on a hierarchy of valuation techniques, which is determined on whether the inputs to those valuation techniques are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect our market assumptions. These two types of inputs create a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows:

 	 	 	Level 1:	  	 	Quoted prices for identical instruments in active markets.	
 	 	 	
 	 	 	Level 2:	  	 	Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets
that are not active; and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets.	
 	 	 	
 	 	 	Level 3:	  	 	Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable.	
Our defined benefit plan assets are valued under methods of fair value. All of the securities held by the plan are publicly traded and highly liquid. Therefore, the majority of the securities are valued under Level 1 and one security is valued under Level 2 using quoted prices for identical or similar securities.
Defined benefit plan
We maintain a pension plan covering certain of our employees in the 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. See  “Fair value measurements”  above in regard to pension plan 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. 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.

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. In the future, we may enter into hedging arrangements designed to mitigate foreign currency fluctuations. See “Risk Factors — We are subject to foreign currency risk as a result of our international operations.”  in Part I, Item 1A of this Annual Report for additional information.
Effect on Reporting Income
Certain of our subsidiaries’ have a functional currency that differs from the currencies in which some of their expenses are denominated. Our income and expenses are based on a mix of currencies and a decline in one currency relative to the other currencies could adversely affect our results of operations. Furthermore, our results of operations are reported in U.S. dollars, which is our reporting currency. In the event the U.S. dollar weakens against a foreign currency, we will experience a currency transaction loss, which could adversely affect our results of operations. If a foreign currency were to weaken (or strengthen) by 1.0% against the U.S. dollar, we would experience currency transaction gain (or loss) of less than $1 million per quarter.
Foreign Currency Transaction Risk
We also are subject to foreign currency risk arising from intercompany transactions that are expected to be settled in cash in the near term where the cash balances are held in denominations other than our subsidiaries’ functional currency. If exchange rates weaken against the functional currency, we would incur a remeasurement gain in the value of the cash balances, and if the exchange rates strengthen against the functional currency, we would incur a remeasurement loss in the value of the cash balances, assuming the net monetary asset balances remained constant. Our ultimate realized gain or loss with respect to currency fluctuations will generally depend on the size and type of transaction, the size and currencies of the net monetary assets and the changes in the exchange rates associated with these currencies. If the Chinese Yuan, the Taiwanese dollar, the Euro and the British Pound Sterling were to weaken (or strengthen) by 1.0% against the U.S. dollar, we would experience currency transaction gain (or loss) of less than $1 million. Net foreign exchange transaction gains (or losses) are included in other income and expense.
Foreign Currency Translation Risk
When our foreign subsidiaries’ books are maintained in their functional currency, fluctuations in foreign currencies impact the amount of total assets and liabilities that we report for our foreign subsidiaries upon the translation of these amounts into U.S. dollars for reporting purposes. All elements of the subsidiaries’ financial statements, except for stockholders’ equity accounts, are translated using a currency exchange rate. Assets and liabilities denominated in foreign currencies are translated at the exchange rate on the balance sheet date. Income and expense accounts denominated in foreign currencies are translated at the weighted–average exchange rate during the period presented. Resulting translation adjustments are recorded as a separate component of accumulated other comprehensive income or loss within stockholders’ equity in the consolidated balance sheets, which are accumulated in this account until sale or liquidation of the foreign entity investment, at which time they are reported as adjustments to the gain or loss on sale of investment.
Foreign Currency Denominated Defined Benefit Plans
We have a contributory defined benefit plan that covers certain employees in the U.K. 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. December 31 is our annual measurement date and on measurement date, defined benefit plan assets are 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, 2011, the plan was underfunded and a liability of approximately $14 million was reflected in our consolidated financial statements as a noncurrent liability. The amount recognized in accumulated other comprehensive income was a net loss of $5 million. If the British Pound Sterling were to (weaken) or strengthen by 1.0% against the U.S. dollar, we would
 
-42-

Table of Contents
experience currency translation liability (decrease) or increase of less than $1 million. The weighted–average discount rate assumption used to determine benefit obligations as of December 31, 2011 was 5.1%. A 0.2% increase/(decrease) in the discount rate used to calculate the net period benefit cost for the year would reduce annual benefit cost by less than $1 million. A 0.2% increase/(decrease) in the discount rate used to calculate the year–end projected benefit obligation would increase/(decrease) the year–end projected benefit obligation by approximately $4 million. The expected return on plan assets is determined based on historical and expected future returns of the various assets classes and as such, each 1.0% increase/(decrease) in the expected rate of return assumption would increase/(decrease) the net period benefit cost by approximately $1 million. The asset value of the defined benefit plan has been volatile in recent years due primarily to wide fluctuations in the U.K. equity markets and bond markets. See “Risk Factors— Due to the recent 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 financial condition. ” in Part I, Item 1A of this Annual Report for additional information.
Interest Rate Risk
We have credit facilities with financial institutions in the U.S., 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 a matter of policy, we do not enter into derivative transactions for speculative purposes. As of December 31, 2011, our outstanding principal debt under our interest-bearing credit agreements was $8 million and $3 million used for import and export guarantees. Based on an increase or decrease in interest rates by 1.0% for the year on our credit facilities, our annual interest rate expense would increase or decrease by less than $1 million.
Political Risk
We have a significant portion of our assets in mainland China, Taiwan and the U.K. 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 additional information.
Inflation Risk
Inflation did not have a material effect on net sales or net income in fiscal year 2011. A significant increase in inflation could affect future performance.
Credit Risk
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. We provide credit to customers in the ordinary course of business and perform ongoing credit evaluations, while at times providing extended terms. We believe that our exposure to concentrations of credit risk with respect to trade receivables is largely mitigated by dispersion of our customers over various geographic areas, operating primarily in electronics manufacturing and distribution. We believe our allowance for doubtful accounts is sufficient to cover customer credit risks.

Disclosure Controls and Procedures
Our Chief Executive Officer, Keh-Shew Lu, and Chief Financial Officer, Richard D. White, 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 of 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, 2011.
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 control over financial reporting. The report of Moss Adams LLP is contained in this Annual Report.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
The Board of Directors and Stockholders
Diodes Incorporated and Subsidiaries
We have audited the accompanying consolidated balance sheets of Diodes Incorporated and Subsidiaries (the “Company”) as of December 31, 2011 and 2010, and the related consolidated statements of income, stockholders’ equity and cash flows for each of the three years in the period ended December 31, 2011. We also have audited the Company’s internal control over financial reporting as of December 31, 2011, 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 consolidated financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall consolidated 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, 2011 and 2010, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2011, 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, 2011, based on criteria established in  Internal Control—Integrated Framework  issued by the Committee of Sponsoring Organizations of the Treadway Commission.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(Table amounts in thousands except per share data)
NOTE 1—SUMMARY OF OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES
Nature of operations – Diodes Incorporated and its subsidiaries (collectively, the “Company”) is a leading global manufacturer and supplier of high-quality, application specific standard products within the broad discrete, logic and analog semiconductor markets, serving the consumer electronics, computing, communications, industrial and automotive markets. These products include diodes, rectifiers, transistors, MOSFETs, protection devices, functional specific arrays, single gate logic, amplifiers and comparators, Hall-effect and temperature sensors, power management devices including LED drivers, DC-DC switching and linear voltage regulators and voltage references along with special function devices including USB power switches, load switches, voltage supervisors and motor controllers. The products are sold primarily throughout Asia, North America and Europe.
Principles of consolidation – The consolidated financial statements include the accounts of Diodes Incorporated, its wholly-owned subsidiaries and its controlled majority-owned subsidiaries. The Company accounts for equity investments in companies over which it has the ability to exercise significant influence, but does not hold a controlling interest, under the equity method, and it records its proportionate share of income or losses in interest and other, net in the consolidated statements of income. All significant intercompany balances and transactions have been eliminated.
Revenue recognition – Revenue is recognized when there is persuasive evidence that an arrangement exists, when delivery has occurred, when the 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 product is shipped to the customers. Generally, the Company recognizes revenue upon shipment to manufacturers (direct ship) as well as upon sales to distributors using the “sell in” model, which is when product is shipped to the distributors (point of purchase).
Certain customers have limited rights of return and/or are entitled to price adjustments on products held in their inventory or upon sale to their end customers. The Company reduces net sales in the period of sale for estimates of product returns, distributor price adjustments and other allowances. The Company’s reserve estimates are based upon historical data as well as projections of sales, distributor inventories, price adjustments, average selling prices and market conditions. Actual returns and adjustments could be significantly different from the Company’s estimates and provisions.
The Company records allowances/reserves for the following items: (i) ship and debit, which arise when the Company, from time to time based on market conditions, issues credit to certain distributors upon their shipments to their end customers, (ii) stock rotation, which are contractual obligations that permit certain distributors, twice a year, to return a portion of their inventory based on historical shipments to them in exchange for an equal and offsetting order, and (iii) price protection, which arise when market conditions cause average selling prices to decrease and the Company issues credit to certain distributors on their inventory.
Ship and debit reserves are recorded as a reduction to net sales with a corresponding reduction to accounts receivable. Stock rotation reserves are recorded as a reduction to net sales with a corresponding reduction to cost of goods sold for the estimated cost of inventory that is expected to be returned. Price protection reserves are recorded as a reduction to net sales with a corresponding increase in accrued liabilities. Revenue is reduced in the period of sale for estimates of product returns and other allowances including distributor adjustments, which were approximately $34 million, $32 million and $18 million in 2011, 2010 and 2009, respectively.
Product warranty – The Company generally warrants its products for a period of one year from the date of sale. Historically, warranty expense has not been material.
Cash and cash equivalents – The Company considers all highly liquid investments with maturity of three months or less at the date of purchase to be cash equivalents. The Company currently maintains substantially all of its day-to-day operating cash balances with major financial institutions.
Allowance for doubtful accounts – The Company evaluates the collectability of its accounts receivable based upon a combination of factors, including the current business environment and historical experience. If the Company is aware of a customer’s inability to meet its financial obligations, it records an allowance to reduce the receivable to the amount it reasonably believes will be collected from the customer. For all other customers, the Company records 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. Accounts receivable are presented net of a valuation allowances, which were approximately $2 million, $1 million and $1 million in 2011, 2010 and 2009, respectively.

Inventories – Inventories are stated at the lower of cost or market value. Cost is determined principally by the first-in, first-out method. Cost includes materials, labor, and manufacturing overhead related to the purchase and production of inventories. Any write-down of inventory to the lower of cost or market at the close of a fiscal period creates a new cost basis that subsequently would not be marked up based on changes in underlying facts and circumstances. On an on-going basis, the Company evaluates inventory 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 the Company’s manufacturing facilities. If the Company’s review indicates a reduction in utility below carrying value, it reduces inventory to a new cost basis. If future demand or market conditions are different than the Company’s current estimates, an inventory adjustment may be required, and would be reflected in cost of goods sold in the period the revision is made.
Property, plant and equipment – Purchased property, plant and equipment is recorded at historical cost and acquired property, plant and equipment is recorded at fair value on the date of acquisition. Property, plant and equipment is depreciated using straight-line methods over the estimated useful lives, which range from 20 to 55 years for buildings and 3 to 10 years for machinery and equipment. The estimated lives of leasehold improvements range from 3 to 5 years, and are amortized over the shorter of the remaining lease term or their estimated useful lives.
Goodwill and other intangible assets – Goodwill is tested for impairment on an annual basis, on October 1, and between annual tests if indicators of potential impairment exist. For 2011, the Company elected to early adopt Financial Accounting Standards Board (“FASB”) Accounting Standards Update (“ASU”) No. 2011-08,  Intangibles-Goodwill and Other (Topic 350): Testing Goodwill for Impairment . ASU No. 2011-08 simplified goodwill impairment testing by allowing the Company to first assess qualitatively whether it is necessary to perform step one of the two-step annual goodwill impairment test. The Company is required to perform step one and calculate the fair value of its reporting units only if the Company concludes that it is more likely than not that a reporting unit’s fair value is less than its carrying value (that is, a likelihood of more than 50%). The qualitative analysis, which we refer to as step zero, was performed and the Company considered all relevant factors specific to its reporting units. Some factors considered in step zero were macroeconomic conditions, industry and market considerations, cost factors, overall financial performance, events affecting a reporting unit and other relevant entity-specific events. The Company’s conclusion of step zero was that goodwill is deemed to be not impaired and no further testing is required until the next annual test date (or sooner if conditions or events before that date raise concerns of potential impairment in the business).
For all years prior to 2011, 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. No impairment of goodwill has been identified during any of the periods presented.
Impairment of long-lived assets – The Company’s long-lived assets are reviewed at least annually and whenever events or changes in circumstances indicate that the carrying value may not be recoverable .  The Company considers assets to be impaired if the carrying value exceeds the undiscounted projected cash flows from operations. If impairment exists, the assets are written down to fair value or to the projected discounted cash flows from related operations. As of December 31, 2011, the Company expects the remaining carrying value of assets to be recoverable. No impairment of long-lived assets has been identified during any of the periods presented. The weighted average amortization period for amortizable intangible assets is approximately 7 years.
Income taxes – Income taxes are accounted for 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 the Company’s assets and liabilities. If it is more likely than not that some portion of deferred tax assets will not be realized, a valuation allowance is recorded.
Generally accepted accounting principles in the United States of America (“GAAP”) prescribes a comprehensive model for how companies should recognize, measure, present, and disclose in their financial statements uncertain tax positions taken or expected to be taken on a tax return. Tax positions shall initially be recognized in the financial statements when it is more likely than not the position will be sustained upon examination by the tax authorities. Such tax positions shall initially and subsequently be measured as the largest amount of tax benefit that is greater than 50% likely of being realized upon ultimate settlement with the tax authority assuming full knowledge of the position and all relevant facts.
Research and development costs – Research and development costs are expensed as incurred.

Shipping and handling costs – Shipping and handling costs for products shipped to customers, which are included in selling, general and administrative expenses, were $6 million, $5 million and $3 million for the years ended December 31, 2011, 2010 and 2009, respectively.
Concentration of credit risk – Financial instruments, which potentially subject the Company to concentrations of credit risk, include trade accounts receivable. Credit risk is limited by the dispersion of the Company’s customers over various geographic areas, operating primarily in electronics manufacturing and distribution. The Company performs on-going credit evaluations of its customers, and generally requires no collateral. Historically, credit losses have not been significant.
The Company currently maintains substantially all of its day-to-day cash balances with major financial institutions. Cash balances are usually in excess of Federal and/or foreign deposit insurance limits.
Valuation of financial instruments – The carrying value of the Company’s financial instruments, including cash and cash equivalents, accounts receivable, accounts payable, working capital line of credit, and long-term debt approximate fair value due to their current market conditions, maturity dates and other factors.
Use of estimates – The preparation of financial statements in conformity with GAAP requires that management make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. The level of uncertainty in estimates and assumptions increases with the length of time until the underlying transactions are completed. Actual results may differ from these estimates in amounts that may be material to the consolidated financial statements and accompanying notes.
Earnings per share – Earnings per share are based upon the weighted average number of shares of common stock and common stock equivalents outstanding, including those related to share-based compensation and the Company’s 2.25% convertible senior notes due 2026 (“Notes”). Earnings per share are computed using the “treasury stock method.”
For the years ended December 31, 2011, 2010 and 2009, options and share grants outstanding for 2 million shares, 2 million shares and 3 million shares, respectively, of common stock have been excluded from the computation of diluted earnings per share because their effect was anti-dilutive.

Share-based compensation – The Company uses the Black-Scholes-Merton model to determine the fair value of stock options on the date of grant and recognizes compensation expense for stock options on a straight-line basis. Restricted stock grants are measured based on the fair market value of the underlying stock on the date of grant and compensation expense for restricted stock grants is recognized on a straight-line basis over the requisite service period.
The amount of compensation expense recognized using the Black-Scholes-Merton model requires the Company to exercise judgment and make assumptions relating to the factors that determine the fair value of its 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 judgment. In addition, the Company is required to estimate the expected forfeiture rate and only recognize expense for those stock options expected to vest. The Company estimates the forfeiture rate based on historical experience, and to the extent its actual forfeiture rate is different from its estimate, share-based compensation expense is adjusted accordingly.
Functional currencies and foreign currency translation – The functional currency for most of the Company’s international operations is the U.S. dollar. In some cases, we enter into transations involving foreign currencies. Some subsidiaries functional currency is their local currency, as the Company believes it is the appropriate currency. The Company believes the New Taiwan (“NT”) dollar is the functional currency at Diodes Taiwan Inc. and the British Pound Sterling (“GBP”) is the functional currency at Diodes Zetex Limited, which most appropriately reflects the current economic facts and circumstances of their operations. Assets and liabilities denominated in foreign currencies are translated at the exchange rate on the balance sheet date. Income and expense accounts denominated in foreign currencies are translated at the weighted-average exchange rate during the period presented. Resulting translation adjustments are recorded as a separate component of accumulated other comprehensive income or loss within stockholders’ equity in the consolidated balance sheets. Included in other income are foreign exchange losses of $1 million, $0 million and $5 million for the years ended December 31, 2011, 2010 and 2009, respectively.
The Company uses the U.S. dollar as the functional currency in Diodes Hong Kong Limited, Shanghai Kai Hong Electronic Co., Ltd. and Shanghai Kai Hong Technology Co., Ltd. as substantially all monetary transactions are made in U.S. dollars, and other significant economic facts and circumstances currently support that position. As these factors may change in the future, the Company periodically assesses its position with respect to the functional currency of its foreign subsidiaries.
Defined benefit plan – The Company maintains pension plans covering certain of its employees in the U.K. and Germany. The overfunded or underfunded status of pension and postretirement benefit plans are recognized on the balance sheet. Actuarial gains and losses, prior service costs or credits, are recognized in other comprehensive income, net of tax effects, until they are amortized as a component of net periodic benefit cost. 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.
Investment in joint ventures – Investment in joint ventures over which the Company does not 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 which 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,” the Company 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 the Company’s longer-term intent of retaining the investment in the investee. As of December 31, 2011, and 2010 the value of the Company’s investment in joint ventures of $1 million, are included in the Company’s consolidated balance sheet as other assets.
Noncontrolling interest – Noncontrolling interest (previously referred to as minority interest) primarily relate to the minority investors’ share of the earnings of certain China subsidiaries. Noncontrolling interests are a separate component of equity and not as a liability, which increases or decreases in the Company’s ownership interest, that leave control intact, be treated as equity transactions, rather than step acquisitions or diluted gain or losses. The noncontrolling interest in the Company’s subsidiaries and their equity balances are reported separately in the consolidated financial statements, and activities of these subsidiaries are included therein.
Contingencies – From time to time, the Company may be involved in a variety of legal matters that arise in the normal course of business. Based on information available, the Company evaluates the likelihood of potential outcomes. The Company records the appropriate liability when the amount is deemed probable and reasonably estimable. In addition, the Company does not accrue for estimated legal fees and other directly related costs as they are expensed as incurred.

Comprehensive income (loss) – GAAP generally requires that recognized revenue, expenses, gains and losses be included in net income. Although certain changes in assets and liabilities are reported as separate components of the equity section of the consolidated balance sheet, such items, along with net income, are components of comprehensive income or loss. The components of other comprehensive income or loss include foreign currency translation adjustments, unrealized gain or loss on defined benefit plan, foreign currency gain (loss) on forward contracts and other items. Accumulated other comprehensive loss was $(36) million, $(45) million and $(48) million at December 31, 2011, 2010 and 2009, respectively.

Reclassifications – Certain amounts from prior periods have been reclassified to conform to the current years’ presentation.
Recently issued accounting pronouncements – In June 2011, the FASB issued ASU No. 2011-05, Comprehensive Income (Topic 220): Presentation of Comprehensive Income.  ASU No. 2011-05 provides two options for presenting other comprehensive income (OCI), which previously has typically been placed near the statement of equity. The amendments require an OCI statement to be included with the income statement, which together will make a statement of total comprehensive income or separate from the income statement, but the two statements will have to appear consecutively within a financial report. The amendments also required that reclassification adjustments for items that are reclassified from other comprehensive income to net income in the statement(s) be presented on the face of the financial statements. However, in December 2011 the FASB issued ASU No. 2011-12, Comprehensive Income (Topic 220): Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05  that deferred the effective date for amendments to the presentation of reclassifications of items out of other comprehensive income. ASU No. 2011-12 was issued to allow the FASB time to redeliberate whether it is necessary to require entities to present reclassification adjustments, by component, in both the statement where net income is presented and the statement where comprehensive income is presented for both interim and annual financial statements, as originally required under ASU No. 2011-05. During the FASB’s redeliberation period, entities will continue to report reclassifications out of accumulated other comprehensive income using guidance in effect before ASU No. 2011-05 was issued. ASU No. 2011-05 is to be applied retrospectively and is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2011. The adoption of this ASU will have no effect on the Company’s reported financial condition, financial performance or cash flows and the Company will select one of the two presentation options in its Quarterly Report on Form 10-Q for the quarterly period ended March 31, 2012.

NOTE 2—FAIR VALUE MEASUREMENTS
Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. A fair value measurement assumes that the transaction to sell the asset or transfer the liability occurs in the principal market for the asset or liability or, in the absence of a principal market, the most advantageous market for the asset or liability. The price in the principal (or most advantageous) market used to measure the fair value of the asset or liability shall not be adjusted for transaction costs. An orderly transaction is a transaction that assumes exposure to the market for a period prior to the measurement date to allow for marketing activities that are usual and customary for transactions involving such assets and liabilities; it is not a forced transaction. Market participants are buyers and sellers in the principal market that are (i) independent, (ii) knowledgeable, (iii) able to transact and (iv) willing to transact.
The Company uses valuation techniques that are consistent with the market approach, the income approach and/or the cost approach. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets and liabilities. The income approach uses valuation techniques to convert future amounts, such as cash flows or earnings, to a single present amount on a discounted basis. The cost approach is based on the amount that currently would be required to replace the service capacity of an asset (replacement costs). Valuation techniques should be consistently applied. Inputs to valuation techniques refer to the assumptions that market participants would use in pricing the asset or liability. Inputs may be observable, meaning those that reflect the assumptions market participants would use in pricing the asset or liability developed based on market data obtained from independent sources, or unobservable, meaning those that reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. These two types of inputs create a three-tier fair value hierarchy that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The fair value hierarchy is as follows:
Level 1 Inputs – Unadjusted quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date.
Level 2 Inputs – Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (for example, interest rates, volatilities, prepayment speeds, loss severities, credit risks and default rates) or inputs that are derived principally from or corroborated by observable market data by correlation or other means.
Level 3 Inputs – Significant unobservable inputs that reflect an entity’s own assumptions that market participants would use in pricing the assets or liabilities.
On September 7, 2011, the Company purchased 10 million shares of the common stock of Eris Technology Corporation (“Eris”), a publicly traded company listed as an Emerging Stock on the Taiwan OTC Exchange (TWO) that provides design, manufacturing and after-market services for diode products. The Company paid NT$39 per share or NT$390 million (approximately US$14 million), which represents an approximately 30 percent ownership in Eris after the transaction. As of December 31, 2011, the Company held 12,413,604 shares of Eris.
The accounting rules permit a company to choose, at specified election dates, to measure at fair value certain eligible financial assets and liabilities that are not currently required to be measured at fair value. The specified election dates include, but are not limited to, the date when an entity first recognizes the item, when an entity enters into a firm commitment or when changes in the financial instrument causes it to no longer qualify for fair value accounting under a different accounting standard. The fair value option may be elected for each entire financial instrument, but need not be applied to all similar instruments. Once the fair value option has been elected, it is irrevocable. Unrealized gains and losses on items for which the fair value option has been elected will be reported in other income (expense).
The Company has elected the fair value option for the shares of Eris common stock. Fair value is the price that would be received on the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The shares of Eris common stock will be valued under the fair value hierarchy as a Level 1 Input, which is the quoted price (unadjusted) in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date.

Certain financial assets and financial liabilities are measured at fair value on a nonrecurring basis; that is, the instruments are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances (for example, when there is evidence of impairment). Financial assets and financial liabilities measured at fair value on a non-recurring basis were not significant at December 31, 2011 and 2010. Certain non-financial assets and non-financial liabilities measured at fair value on a recurring and non-recurring basis include goodwill, other intangible assets and other non-financial long-lived assets.

On November 25, 2009 the Company entered into a credit agreement with Bank of America, N.A. (“Bank of America”) as modified by a certain letter dated as of March 31, 2010, the First Amendment to Credit Agreement dated as of July 16, 2010, the Second Amendment to Credit Agreement dated as of November 24, 2010, the Third Amendment to Credit Agreement dated as of February 4, 2011 and the Fourth Amendment to Credit Agreement dated as of November 23, 2011 (collectively the “Credit Agreement”). The Credit Agreement provides for a $10 million revolving credit facility (the “Revolver”) and a $10 million uncommitted facility (the “Uncommitted Facility”). The Revolver includes a $2 million sublimit for letters of credit. Both the Revolver and the Uncommitted Facility mature on January 22, 2012 (the “Maturity Date”). Any borrowing and obligations under the Revolver or under the Uncommitted Facility is secured by accounts, chattel paper, deposit accounts and inventory, and all dividends, distributions, and income attributable to proceeds, products, additions to, substitutions, replacements and supporting obligations for, model conversions, and accessions of the foregoing, of the Company and of certain of its subsidiaries. Certain subsidiaries of the Company also guaranty any borrowing and obligations and pledge their interests to Bank of America in certain subsidiary stock owned by such subsidiary guarantors.
In addition, the Credit Agreement contains certain restrictive and financial covenants, including, but not limited to, the following: (a) the Company shall maintain on a consolidated basis a Fixed Charge Coverage Ratio of not less than 2.00 to 1.0 and a Quick Ratio of not less than 1.50 to 1.0 (excluding the Company’s Notes for both ratios); (b) the Company and its subsidiaries shall not create, incur, assume or suffer to exist any lien upon any of its property, assets or revenues except as specified in the Credit Agreement; (c) the Company and its subsidiaries shall not make any investments except as specified in the Credit Agreement; (d) the Company and its subsidiaries shall not create, incur, assume or suffer to exist any indebtedness except as specified in the Credit Agreement; (e) the Company and its subsidiaries shall not dissolve or merge or consolidate with or into another entity except as specified in the Credit Agreement; (f) the Company and its subsidiaries shall not make any disposition except as specified in the Credit Agreement; (g) the Company and its subsidiaries shall not make any restricted payment, or issue or sell any equity interests, except as specified in the Credit Agreement; (h) the Company and its subsidiaries shall not engage in any material line of business substantially different from those lines of business that are currently conducted by the Company and its subsidiaries; (i) the Company and its subsidiaries shall not enter into any transaction of any kind with any affiliate of the Company except as specified in the Credit Agreement; (j) the Company and its subsidiaries shall not enter into certain burdensome contractual obligations except as specified in the Credit Agreement; and (k) the Company and its subsidiaries shall not use the proceeds of any credit extension to purchase or carry margin stock or to extend credit to others for the purpose of purchasing or carrying margin stock or to refund indebtedness originally incurred for such purpose. As of December 31, 2011, the Company was in compliance with these covenants.

Uncertain Tax Positions
In accordance with the provisions related to accounting for uncertainty in income taxes, the Company recognizes the benefit of a tax position if the position is “more likely than not” to prevail upon examination by the relevant tax authority. A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows:
 
 	 	 	$000,000,000	 	 	 	$000,000,000	 	
 	  	2011	 	 	2010	 	
Balance at January 1,	  	$	9,173	  	 	$	8,064	  	
Additions based on tax positions related to the current year	  	 	2,233	 	 	 	1,934	 	
Reductions for prior years tax positions	  	 	(1,229	) 	 	 	(825	) 	
 	  	 	 	 	 	 	 	 	
Balance at December 31,	  	$	10,177	  	 	$	9,173	  	
 	  	 	 	 	 	 	 	 	
It is reasonably possible that the amount of the unrecognized benefit with respect to certain of the Company’s unrecognized tax positions will significantly increase or decrease within the next 12 months. These changes may be the result of settlements of ongoing audits or competent authority proceedings. At this time, an estimate of the range of the reasonably possible outcomes cannot be made.
The Company files income tax returns in the U.S. federal jurisdiction and in various state and foreign jurisdictions. The Company is no longer subject to U.S. federal income tax examinations by tax authorities for tax years before 2007. With respect to state and local jurisdictions and countries outside of the U.S., with limited exceptions, the Company is no longer subject to income tax audits for years before 2006. Although the outcome of tax audits is always uncertain, the Company believes that adequate amounts of tax, interest and penalties, if any, have been provided for in the Company’s reserve for any adjustments that may result from future tax audits. The Company recognizes accrued interest and penalties, if any, related to unrecognized tax benefits in income tax expense. The Company had an insignificant amount of accrued interest and penalties at December 31, 2011 and December 31, 2010.
Deferred Taxes
At December 31, 2011 and 2010, the Company’s deferred tax assets and liabilities are comprised of the following items:

At December 31, 2011, the Company had federal and state tax credit carryforwards of approximately $24 million and $1 million, respectively which are available to offset future income tax liabilities. The federal tax credit carryforwards begin to expire in 2012 and the state tax credit carryforwards will begin to expire in 2020. The Company determined that it is more likely than not that a portion of its federal foreign tax credit carryforwards will expire before they are utilized. Accordingly, the Company recorded valuation allowances of $1 million, $2 million and $4 million during the years ended December 31, 2011, 2010 and 2009, respectively.
At December 31, 2011, the Company had federal and state net operating loss (“NOL”) carryforwards of approximately $1 million and $17 million, respectively, which are available to offset future regular and alternative minimum taxable income. The state NOL carryforwards will begin to expire in 2013. The Company determined that it is more likely than not that the state NOL carryforwards will expire before they are fully utilized and recorded a full valuation allowance on the state NOL carryforwards in prior years. The Company maintained this full valuation allowance for the year ended December 31, 2011.
Supplemental Information
Funds repatriated from foreign subsidiaries to the U.S. may be subject to federal and state income taxes. The Company intends to permanently reinvest overseas all of its earnings from its foreign subsidiaries; accordingly, U.S. taxes are not being recorded on undistributed foreign earnings. As of December 31, 2011, the Company has undistributed earnings from its non-U.S. operations of approximately $265 million (including approximately $33 million of restricted earnings which are not available for dividends). Additional federal and state income taxes of approximately $45 million would be required should such earnings be repatriated to the U.S.
The impact of tax holidays decreased the Company’s tax expense by approximately $7 million, $8 million and $7 million for the years ended December 31, 2011, 2010 and 2009, respectively. The benefit of the tax holidays on both basic and diluted earnings per share for the year ended December 31, 2011 was approximately $0.15. The benefit of the tax holidays on basic and diluted earnings per share for the year ended December 31, 2010 was approximately $0.19 and $0.18, respectively. The benefit of the tax holidays on both basic and diluted earnings per share for the year ended December 31, 2009 was approximately $0.17.
During 2011, the Company realized a tax benefit of $15 million related to exercises of non-qualified stock options and to disqualified dispositions of incentive stock options. The Company credited additional paid-in capital to record this benefit.
NOTE 12—EMPLOYEE BENEFIT PLANS
Defined Benefit Plan
The Company has adopted a contributory defined benefit plan that covers certain employees in the U.K. 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. The Company determined the fair value of the defined benefit plan assets and utilizes 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 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.
Net period benefit costs associated with the defined benefit were less than $1 million and approximately $1 million for the year ended December 31, 2011 and 2010, respectively. All unrecognized actuarial gains and losses, prior service costs and accumulated other comprehensive income are eliminated and the balance sheet liability is set equal to the funded status of the defined benefit plan at acquisition date.

The Company applies the “10% corridor” approach to amortize unrecognized actuarial gains (losses). Under this approach, only actuarial gains (losses) that exceed 10% of the greater of the projected benefit obligation or the market-related value of the plan assets are amortized. For the year ended December 31, 2011, the plans total recognized loss decreased by $3 million. The variance between the actual and expected return to plan assets during 2011 increased the total unrecognized net loss by less than $1 million. The total unrecognized net loss is less than 10% of the projected benefit obligation and 10% of the plan assets. Therefore, there will not be any excess amount to be amortized over the average term to retirement of plan participants not yet in receipt of pension, which as of December 31, 2011 the average term was 13 years.
The following weighted-average assumptions were used to determine net periodic benefit costs for the year ended December 31:

 	  	2011	 	 	2010	 	
Discount rate	  	 	5.1	% 	 	 	5.4	% 	
Expected long-term return on plan assets	  	 	5.6	% 	 	 	6.6	%

 	  	2011	 	 	2010	 	
Discount rate	  	 	5.1	% 	 	 	5.4	% 	
The expected long-term return on plan assets was determined based on historical and expected future returns of the various asset classes. The plans investment policy includes a mandate to diversify assets and invest in a variety of asset classes to achieve its expected long-term return and is currently invested in a variety of funds representing most standard equity and debt security classes. Trustees of the plan may make changes at any time. The following summarizes the plan asset allocations of the assets in the plan and expected long-term return by asset category:

Asset category	  	Expected long-term return	 	 	Assets allocation	 	
Cash	  	 	0.5	% 	 	 	0.6	% 	
Equity securities	  	 	7.0	% 	 	 	42.3	%

Total	  	 	5.6	% 	 	 	100	% 	
Benefit plan payments are primarily made from funded benefit plan trusts and current assets. The following summarizes the expected future benefit payments, including future benefit accrual, as of December 31, 2011:

Year	  	 	 	
2012	  	$	3,388

The Company adopted a payment plan that Zetex had in place with the trustees of the defined benefit plan, in which the Company paid approximately £1 million GBP (approximately $1.6 million based on a USD:GBP exchange rate of 1.6:1) every year from 2009 through 2011. The Company and the trustees are in discussions to extend the payment scheme through 2019.
The Company’s overall defined benefit plan investment strategy is to achieve a mix of investments for long-term growth and for near-term benefit payments with a wide diversification of asset types and fund strategies. The target allocations for plan assets are 48% equity securities, 40% corporate bonds and government securities, and 12% to absolute return funds. Equity securities primarily include investments in large-cap and mid-cap companies primarily located in the U.K. Fixed income securities include corporate bonds of companies from diversified industries, and U.K. government bonds. The absolute return fund is mainly invested in a mixture of equities and bonds.

The plan’s trustees appoint fund managers to carry out all the day-to-day functions relating to the management of the fund and its administration. The fund managers must invest their portion of the plan’s assets in accordance with their investment manager agreement agreed by the trustees. The trustees are responsible for agreeing these investment manager agreements and for deciding on the portion of the plan’s assets that will be invested with each fund manager. When making decisions, the trustees take advice from experts including the plan’s actuary and also consult with the Company.
The following table summarizes the major categories of the plan assets:

Fair value is taken to mean the bid value of securities, as supplied by the fund managers. All the plan’s securities are publically traded and highly liquid. Therefore, the majority of the securities are valued under Level 1 and one security is valued under Level 2 using quoted prices for identical or similar securities. The plan does not hold any level 3 securities. See Note 2 for additional information regarding fair value and Levels 1, 2 and 3.
The investment manager agreements require the fund managers to invest in a diverse range of stocks and bonds across each particular asset class. The stocks held by the plan in a particular asset class should therefore match closely the underlying stocks in the relevant index. The Company believes that this leads to minimal concentration of risk within each asset class; although it recognizes that some asset classes are inherently more risky than others.
The Company also has pension plans in Asia for which the benefit obligation, fair value of the plan assets and the funded status amounts are deemed immaterial and therefore, not included in the amounts or assumptions above.
401(k) Retirement Plan
The Company maintains a 401(k) retirement plan (the Plan) for the benefit of qualified employees at its U.S. locations. Employees who participate may elect to make salary deferral contributions to the Plan up to 100% of the employees’ eligible payroll subject to annual Internal Revenue Code maximum limitations. The Company makes a matching contribution of $1 for every $2 contributed by the participant up to 6% (3% maximum matching) of the participant’s eligible payroll, which vests over four years. In addition, the Company may make a discretionary contribution to the entire qualified employee pool, in accordance with the Plan.
As stipulated by the regulations of China, the Company maintains a retirement plan pursuant to the local municipal government for the employees in China. The Company is required to make contributions to the retirement plan at a rate between 10% and 22% of the employee’s eligible payroll. Pursuant to the Taiwan Labor Standard Law and Factory Law, the Company maintains a retirement plan for the employees in Taiwan, whereby the Company makes contributions at a rate of 6% of the employee’s eligible payroll.

For the years ended December 31, 2011, 2010 and 2009, total amounts expensed under these plans were approximately $5 million, $4 million and $2 million, respectively.
Deferred Compensation Plan
The Company maintains a Non-Qualified Deferred Compensation Plan (the “Deferred Compensation Plan”) for executive officers, key employees and members of the Board of Directors (the “Board”). The Deferred Compensation Plan allows eligible participants to defer the receipt of eligible compensation, including equity awards, until designated future dates. The Company offsets its obligations under the Deferred Compensation Plan by investing in the actual underlying investments. These investments are classified as trading securities and are carried at fair value. At December 31, 2011, these investments totaled approximately $3 million. All gains and losses in these investments are equally offset by corresponding gains and losses in the deferred compensation plan liabilities.
Share-Based Plans
The Company maintains share-based compensation plans for its Board, officers and key employees, which provide for stock options and stock awards under its 1993 ISO Plan, 1993 NQO Plan and 2001 Omnibus Equity Incentive Plan.
NOTE 13—SHARE-BASED COMPENSATION
The following table shows the total compensation cost charged against income for share-based compensation plans, including stock options and share grants, recognized in the statements of income for the years ended December 31, 2011, 2010 and 2009:

 	  	2011	 	  	2010	 	  	2009	 	
Cost of goods sold	  	$	394	 	  	$	350	 	  	$	373	 	
Selling, general and administrative expense	  	 	12,266	 	  	 	11,347	 	  	 	9,203	 	
Research and development expense	  	 	1,043	 	  	 	1,354	 	  	 	1,360	 	
 	  	 	 	 	  	 	 	 	  	 	 	 	
Total share-based compensation expense	  	$	13,703	 	  	$	13,051	 	  	$	10,936	 	
 	  	 	 	 	  	 	 	 	  	 	 	 	
Stock Options—Stock options generally vest in equal annual installments over a four-year period and expire ten years after the grant date. Share-based compensation expense for stock options granted during 2011, 2010 and 2009 was calculated on the date of grant using the following weighted-average forfeiture rates and the Black-Scholes-Merton option-pricing model using the following weighted-average assumptions:

 	  	2011	 	 	2010	 	 	2009	 	
Expected volatility	  	 	52.53	% 	 	 	57.99	% 	 	 	57.92	% 	
Expected term (years)	  	 	7.5	 	 	 	7.3	 	 	 	7.5	 	
Risk free interest rate	  	 	2.37	% 	 	 	2.60	% 	 	 	3.20	% 	
Forfeiture rate	  	 	0.47	% 	 	 	0.88	% 	 	 	2.50	% 	
Dividend yield	  	 	N/A	  	 	 	N/A	  	 	 	N/A	  	
Expected volatility—The Company estimates expected volatility using historical volatility. Public trading volume on options in the Company’s stock is not material. As a result, the Company determined that utilizing an implied volatility factor would not be appropriate. The Company calculates historical volatility for the period that is commensurate with the option’s expected term assumption. For 2011, the expected volatility for grants to officers and the Board is 52.45%, while the expected volatility for grants to all other employees is 53.90%.

Expected term—The Company has evaluated expected term based on history and exercise patterns across its demographic population. The Company believes that this historical data is the best estimate of the expected term of a new option. For 2011, the expected term for grants to officers and the Board is 8 years, while the expected term for grants to all other employees is 5 years.
Risk free interest rate—The Company estimate the risk-free interest rate based on zero-coupon U.S. treasury securities for a period that is commensurate with the expected term assumption.
Forfeiture rate—The amount of stock-based compensation recognized during a period is based on the value of the portion of the awards that are ultimately expected to vest as forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. The term “forfeitures” is distinguished from “cancellations” or “expirations” and represents only the unvested portion of the surrendered option. This analysis will be re-evaluated at least annually, and the forfeiture rate will be adjusted as necessary.
Dividend yield—The Company historically has not paid a cash dividend on its common stock; therefore this input is not applicable.
Discount for post vesting restrictions—This input is not applicable.
The weighted-average grant-date fair value of options granted during 2011, 2010 and 2009 was $16.55, $11.45, and $9.34, respectively. The total cash received from option exercises was $4 million, $5 million and $2 million during 2011, 2010 and 2009, respectively.
For the years ended December 31, 2011, 2010 and 2009, stock option expense was $5 million, $4 million and $4, respectively.
At December 31, 2011, unamortized compensation expense related to unvested options, net of estimated forfeitures, was approximately $10 million. The weighted average period over which share-based compensation expense related to these options will be recognized is approximately 3 years.

NOTE 15—SEGMENT INFORMATION AND ENTERPRISE-WIDE DISCLOSURES
An operating segment is defined as a component of an enterprise about which separate financial information is available that is evaluated regularly by the chief decision maker, or decision-making group, in deciding how to allocate resources and in assessing performance. The Company’s chief decision-making group consists of the President and Chief Executive Officer, Chief Financial Officer, Senior Vice President of Operations and Senior Vice President of Sales and Marketing. For financial reporting purposes, the Company operates in a single segment, standard semiconductor products, through its various manufacturing and distribution facilities. The Company aggregates its products in a single segment because the products have similar economic characteristics, are similar in production process and manufacture flow, and share the same customers and target end equipment markets.

NOTE 18—SUBSEQUENT EVENTS
On February 1, 2012, the Company entered into a Fifth Amendment to its Credit Agreement Bank of America (the “Lender”). The Fifth Amendment added an additional borrower, Diodes International B.V. (the “BV Entity”), to the Credit Agreement and provides for an additional term loan in the amount of $40 million (the “Term Loan”). The Term Loan matures on January 17, 2015 and bears interest at a rate per annum equal to the Eurocurrency Rate plus 1.25% per annum. One February 1, 2012, BV Entity drew down the full $40 million. The Term Loan is not a revolving credit facility, and any amount repaid may not be reborrowed.
The Fifth Amendment also extends the Maturity Date of the Original Credit Agreement to January 17, 2013 (for loans other than the Term Loan). In addition, it also modifies the provisions for the Eurocurrency Rate by allowing for Interest Periods of 30, 60 or 90 days, rather than requiring all Eurocurrency Rate determinations to be on Interest Periods of one month, and by reducing the interest rate for Eurocurrency Rate committed loans from the Eurocurrency Rate plus 3.0% to the Eurocurrency Rate plus 2.5%.
The Company pledged 65% of the equity Interests in the BV Entity to the Lender as security for all of the obligations of the Borrowers under the Credit Agreement. The Fifth Amendment adds as additional financial covenants that the Interest Coverage Ratio (as defined) will be at least 3.0 to 1.0 on a consolidated basis, and that the Funded Debt to EBITDA Ratio (as defined) will not exceed 2.50 to 1.0 on a consolidated basis. The Fifth Amendment deletes a financial covenant relating to the Fixed Charge Coverage Ratio.

PLEASE NOTE: It is inappropriate for investors to assume the accuracy of any covenants, representations or warranties that may be contained in agreements or other documents filed as exhibits to this Annual Report on Form 10-K. In certain instances the disclosure schedules to such agreements or documents contain information that modifies, qualifies and creates exceptions to the representations, warranties and covenants. Moreover, some of the representations and warranties may not be complete or accurate as of a particular date because they are subject to a contractual standard of materiality that is different from those generally applicable to stockholders and/or were used for the purpose of allocating risk among the parties rather than establishing certain matters as facts. Accordingly, you should not rely on the representations and warranties as characterizations of the actual state of facts at the time they were made or otherwise.
