Item 1. Business

General

Silicon Image is a leading provider of advanced, interoperable connectivity solutions that enable the reliable distribution and presentation of high-definition (HD) content for consumer electronics (CE), mobile, and personal computer (PC) markets. We deliver our technology via semiconductor and intellectual property (IP) products that are compliant with global industry standards and also feature industry leading Silicon Image innovations such as InstaPort™. Our products are deployed by the world’s leading electronics manufacturers in devices such as desktop and notebook PCs, digital televisions (DTVs), Blu-Ray Disc™ players, audio-video receivers, as well as mobile phones, tablets and digital cameras. Silicon Image has driven the creation of the highly successful HDMI® (High-Definition Multimedia Interface) and DVI™ (Digital Visual Interface) industry standards, as well as the MHL™ (Mobile High-Definition Link) and SPMT™ (Serial Port Memory Technology) standards for mobile devices. Via our wholly-owned subsidiary, Simplay Labs LLC, Silicon Image offers manufacturers comprehensive standards interoperability and compliance testing services.

Our customers are product manufacturers in each of our target markets — consumer electronics, mobile, and personal computer. Because we leverage our technologies across different markets, certain of our products may be incorporated into our customers’ products used in multiple markets. We sell our products to original product manufacturers (OEMs) throughout the world using a direct sales force and through a network of distributors and manufacturer’s representatives. Our revenue is generated principally by sales of our semiconductor products, with other revenues derived from IP core/design licensing and royalty and adopter fees from our standards licensing activities. We maintain relationships with the eco-system of companies that make the products that drive digital content creation, distribution and consumption, including major Hollywood studios, service providers, consumer electronics companies and retailers. Through these and other relationships, we have formed a strong understanding of the requirements for distributing and presenting HD digital video and audio in the home and mobile environments. We have also developed a substantial IP base for building the standards and products necessary to promote opportunities for our products.

Historically, we have grown our business by introducing and promoting the adoption of new technologies and standards and entering new markets. We collaborated with other companies to jointly develop the DVI and HDMI standards. Our first products addressed the PC market. We then introduced products for a variety of CE market segments, including the set top box (STB), game console and DTV markets. Most recently, we have focused our research and development efforts and are developing products based on our innovative digital interconnect core technology for the mobile device market, including digital still cameras, HD camcorders, smartphones, and tablets.

We are a Delaware corporation headquartered in Sunnyvale, California. Our Internet website address is www.siliconimage.com.

Standards Activity

We have been directly involved in the following standards efforts:

High-Definition Multimedia Interface (HDMI) Consortium

In 2002, we formed a consortium with Sony, Matsushita Electric Industrial Co. (Panasonic), Philips, Thomson (Technicolor), Hitachi and Toshiba to develop the HDMI specification, a next-generation digital interface for consumer electronics. The HDMI specification is based on our proprietary TMDS® technology, the same technology underlying DVI, the predecessor to the HDMI specification, which we also developed. The HDMI specification combines uncompressed high-definition video, multi-channel audio, and data into a single digital interface to provide crystal-clear digital quality over a single cable. HDMI technology is fully backward compatible with PCs, displays and consumer electronics devices incorporating the DVI standard. As an HDMI founder, we have actively participated in the evolution of the HDMI specification, and we expect to continue our involvement in this and in other digital interface connectivity standards.

We believe that our leadership in the market for HDMI-enabled products is due to our ability to introduce first-to-market semiconductor and IP solutions to our customers and to continue to promote innovation within the standard.

For CE manufacturers, HDMI technology is a low-cost, standardized means of interconnecting CE devices that enables them to provide customers with feature-rich products delivering a true home theater entertainment experience. For PC and monitor manufacturers, HDMI technology enables a PC to connect to digital TVs and monitors at HD quality levels. The market research firm In-Stat estimates that over 500 million HDMI-enabled products shipped worldwide in 2010, contributing to an installed base of over 1.6 billion HDMI enabled products. In addition, over 1000 companies around the world are HDMI adopters.

Mobile High-Definition Link (MHL™) Consortium

In April 2010 Nokia, Samsung, Silicon Image, Sony, and Toshiba formed the MHL consortium to create an industry standard for an audio/video interface to connect mobile phones and other portable CE devices directly to high-definition televisions (HDTVs) and displays. MHL technology is a low pin count HD audio and video serial link specifically defined for connecting mobile devices to HD displays. The MHL specification was developed as a standard for mobile wired video/audio connectivity, which, we believe, will enable the development of standard-compliant mobile and display products across a broad connectivity ecosystem. MHL technology is based on the same TMDS technology used in the DVI and HDMI specifications while only requiring a single TMDS data pair to transmit video to MHL enabled DTVs at resolutions up to 1080p. As a result, the MHL technology requires only 5 signal pins, making it compatible with small, low pin-count connectors in mobile devices. Reduced pin-count connectors are critical in mobile devices given the greatly limited connector space compared to standard consumer electronic devices such as Blu-Ray players and set top boxes. The MHL specification also enables the provision of power to the mobile device when connected to a DTV thus preserving battery life.

Serial Port Memory Technology (SPMT™) Consortium

SPMT is a first-of-its-kind standard for dynamic random access memory (DRAM). SPMT technology is designed to enable extended battery life, bandwidth flexibility, reduced pin count and lower power demand for mobile and portable devices. Demand by mobile service providers for solutions enabling more data-intensive, media-rich capabilities drove the formation of the SPMT Consortium. The SPMT™ consortium was established by Silicon Image, ARM, Hynix Semiconductor, LG Electronics, and Samsung Electronics in 2009, with Marvell joining the consortium in 2010.

Digital Visual Interface (DVI)

In 1998, together with Intel, Compaq, IBM, Hewlett-Packard, NEC and Fujitsu, Silicon Image announced the formation of the Digital Display Working Group (DDWG) and in 1999, published the DVI 1.0 specification. The DVI 1.0 standard defines a high-speed serial data communication link between computers and digital displays. Today, in many applications, DVI is being replaced by the more feature-rich HDMI interface. In the PC market, DVI technology faces competition from DisplayPort, a digital display interface standard promoted by the Video Electronics Standards Association (VESA) and defining a digital audio/video interconnect intended to be used primarily between a computer and its display monitor or a computer and a home-theater system. A number of companies have introduced products based on the DisplayPort standard including AMD, Apple, Dell, nVidia and ST Micro.

Serial Advanced Technology Attachment (SATA)

We have been a contributor to the SATA standard and a supplier of discrete SATA solutions including controllers, storage processors, port multipliers and bridges. Based on serial signaling technology, the SATA standard specifies a computer bus technology for connecting hard disk drives and other devices and was formed by Intel, Dell, Maxtor, Seagate and Vitesse in 1999. We sell SATA semiconductors primarily to merchant motherboard suppliers, computer OEMs and external drive manufacturers.

CE (DTV & Mobile)

HDMI Port Processors. Our HDMI port processors are targeted for CE products, such as DTV’s, AV receivers, sound bars and Home-Theater-In-a-Box (HTIB). Our port processors support the latest version of the HDMI specification and can quickly switch between up to five HDMI inputs using our InstaPort technology. With InstaPort technology, switching time between various HDMI devices attached to a DTV is reduced from approximately 5 seconds to approximately 1 second. In 2010, we introduced an enhanced version of our InstaPort technology - InstaPort™ S technology – which will enable DTV manufacturers with either MHL or HDMI inputs to achieve single-second port switching. In 2010, we introduced two new DTV port processors, the SiI9381A and SiI9387A. The SiI9381A port processor seamlessly interfaces with MHL-enabled mobile devices such as mobile phones and tablets. The SiI9381A also supports four HDMI inputs with InstaPort S – Silicon Image’s single-second HDMI port switching technology and integrates HDMI 1.4 Audio Return Channel and Content Type detection.

HDMI and MHL Transmitters. Our HDMI transmitter products are targeted for CE and mobile products, such as Blu-Ray players, STBs, digital camcorders, smartphones, tablets, and A/V receivers. HDMI transmitters convert digital video and audio into HDMI format enabling products to connect to DTV’s, AV receivers, and PC monitors that have HDMI inputs. Our MHL transmitter products have been optimized for small-form factor and low-power and are targeted for mobile devices, such as digital cameras and camcorders, smartphones, and tablets. MHL transmitters convert digital video into the MHL format enabling mobile devices to connect to DTV’s and monitors with MHL inputs, or alternatively, to connect to DTV’s and monitors with HDMI inputs via an MHL-to-HDMI adapter. In 2010, we introduced the SiI9244, an MHL transmitter for HD video and audio designed for power-sensitive consumer electronics devices such as mobile phones, digital cameras, portable media players and HD camcorders. Eliminating the need for an extra connector, the SiI9244 enables a cost-effective, low-pin count connectivity solution for the delivery of HD content.

MHL-to-HDMI Bridges. Our MHL-to-HDMI bridge products are targeted for docking stations and adapters, connecting new MHL mobile products with existing HDMI enabled DTV’s and monitors. In 2010, we introduced the SiI9292, an MHL-to-HDMI bridge which is integral to the design of low-power, MHL-to-HDMI accessory devices such as docking stations, converters and adapters, enabling HD video and audio connectivity between MHL-ready mobile devices and HDTVs with HDMI inputs.

HDMI Receivers. Our HDMI receiver products are targeted for high-definition displays, such as projectors and PC monitors, as well as AV receivers (AVRs). HDMI receivers convert an incoming encrypted serialized stream to digital video and audio, which is then processed by a television or PC monitor for display.

MHL/HDMI-to-HDMI Bridges. Our MHL/HDMI-to-HDMI bridge products are targeted for high-definition displays, such as PC monitors and DTVs, enabling added support for MHL. In 2010, we introduced the SiI1292, an MHL/HDMI-to-HDMI bridge, that is designed to enable single port displays such as HDTVs, PC monitors, multi-function monitors or HD projectors, to connect to MHL-enabled mobile devices via an MHL cable.

DVI Receivers. Our DVI receiver products are targeted for high-definition PC displays, such as monitors and projectors.

Storage

We provide a full line of SATA controllers used in PC, DVR and network attached storage (NAS) applications. The current generation of controllers provides the SATA Gen II features including eSATA signal levels, 3.0 Gbps, native command queuing (NCQ), hot-plug and port multiplier support.

Our bridge products such as the SiI3811 provide PC OEMs with a solution that connects legacy PATA optical drives to the current generation of motherboard chip sets and are used primarily in desktop and laptop PC applications.

Our SteelVine storage processor architecture integrates the capabilities of a complex redundant array of independent disks (RAID) controller into a single-chip architecture. SteelVine storage processors deliver enterprise-class features such as virtualization, RAID, hot-plug and hot spare, in a single cost-effective system-on-a-chip (SoC). Storage processors are currently shipping in PC motherboards as well as external storage solutions.

Research and Development

Our research and development efforts continue to focus on innovative technologies and standards, higher-bandwidth, lower-power links, efficient algorithms, architectures and feature-rich implementations for CE (including DTV), mobile and PC applications. By utilizing our patented technologies and optimized architectures, we believe our products can scale with advances in semiconductor manufacturing process technology, simplify system design and provide innovative solutions for our customers. As of December 31, 2010, we had been issued 159 United States patents and had 83 United States patent applications pending. Our U.S. issued patents have expiration dates which range from 2015 to 2029, subject to our payment of periodic maintenance fees. Our policy is to seek to protect our intellectual property rights throughout the world by filing counterparts or our US patent applications in select foreign jurisdictions. A discussion of risks related to our intellectual property is set forth in the section of this report titled “Risk Factors”.

We have extensive experience in the areas of high-speed interconnect architecture, circuit design, digital audio-visual (A/V) processor architecture, storage architecture, logic design/verification, firmware/software, digital audio/video systems and storage systems. We have invested and expect that we will continue to invest, significant funds for research and development activities. Our research and development expenses were approximately $55.3 million, $68.2 million and $84.8 million in 2010, 2009 and 2008, respectively, including stock-based compensation expense of $2.6 million, $6.3 million and $7.1 million for 2010, 2009 and 2008, respectively.

Sales and Marketing

We sell our products using a direct sales support and marketing field offices located in North America, Europe, Taiwan, China, Japan and Korea and through a network of distributors located throughout North America, Asia and Europe. Our sales strategy for all products is to achieve design wins with key industry companies in order to grow the markets in which we participate and to promote and accelerate the adoption of industry standards that we support or are developing.

Manufacturing

Wafer Fabrication

Our semiconductor products are designed using standard, complementary metal oxide semiconductor (CMOS) processes, which permit us to use independent wafer foundries to fabricate them. By outsourcing the manufacture of our semiconductor products, we are able to avoid the high cost of owning and operating a semiconductor wafer fabrication facility and to take advantage of our contract manufacturers’ high-volume economies of scale. Outsourcing our manufacturing also gives us direct and timely access to various process technologies. This allows us to focus our resources on the innovation, design and quality of our products.

Our semiconductor products are currently fabricated using 0.35, 0.25, 0.18 and 0.13 micron processes. We continuously evaluate the benefits, primarily the improved performance, costs and feasibility, of migrating our products to smaller geometry process technologies. We have conducted certain development projects for some of our customers, involving smaller geometries, namely 90 nm and 65 nm designs. We rely almost entirely on Taiwan Semiconductor Manufacturing Company (TSMC) to produce all of our semiconductor products. Because of the cyclical nature of the semiconductor industry, capacity availability can change quickly and significantly. Risks related to our sole sourcing of the manufacturing of our products are discussed in the section of this report titled “Risk Factors.”

Assembly and Test

Our semiconductor products are designed to use low-cost standard packages and to be tested with widely available semiconductor test equipment. We outsource all of our packaging and our test requirements. This enables us to take advantage of high-volume economies of scale and supply flexibility and gives us direct and timely access to advanced packaging and test technologies. Since the fabrication yields of our products have historically been high and the costs of our packaging have historically been low, we test our products after they are assembled. This testing method has not caused us to experience unacceptable failures or yields. Our operations personnel closely review the process and control and monitor information provided to us by our foundries. To ensure quality, we have established firm guidelines for rejecting wafers that we consider unacceptable. However, lack of testing prior to assembly could have adverse effects if there are significant problems with wafer processing. Additionally, for newer products and products for which yield rates have not stabilized, we may conduct bench testing using our personnel and equipment, which is more expensive than fully automated testing.

Table of Contents

Quality Assurance

We focus on product quality through all stages of the design and manufacturing process. Our designs are subjected to in depth circuit simulation at temperature, voltage and processing extremes before being fabricated. We also subject pre-production parts to extensive characterization and reliability testing. We also sample early production parts to ensure we are getting the same results as we did during pre-production. We pre-qualify each of our subcontractors through an audit and analysis of the subcontractor’s quality system and manufacturing capability. We also participate in quality and reliability monitoring through each stage of the production cycle by reviewing data from our wafer foundries and assembly subcontractors. We closely monitor wafer foundry production to ensure consistent overall quality, reliability and yields. Our independent foundries and our assembly and test subcontractors have achieved International Standards Organization (ISO) 9001 certification.

Competition

The markets in which we participate are intensely competitive and are characterized by rapid technological change, evolving standards, short product life cycles and decreasing prices. We believe that some of the key factors affecting competition in our markets are levels of product integration, compliance with industry standards, time-to-market, cost, product capabilities, system design costs, intellectual property, customer support, quality and reputation.

In the consumer electronics market, our products are designed into a variety of devices, including DTVs, STBs, Blu-ray players, AV receivers, soundbars, and home theater in a box (HTIBs). Our products compete against discrete HDMI products offered by companies such as Analog Devices, Analogix Semiconductor, Parade Technologies and NXP. Our products face competition from companies integrating HDMI receive or HDMI transmit functionality into SoC’s, such as Broadcom, Intel, MediaTek, Mstar, Trident, Zoran, Marvell, and STM. We also compete in some instances against in-house semiconductor solutions designed by large consumer electronics OEMs.

Mobile

In the mobile market, our products are designed into a variety of devices, including smartphones, tablets, digital still cameras, and camcorders. Our products compete against discrete HDMI, MHL, or DisplayPort products offered by companies such as Analog Devices, Analogix Semiconductor, and NXP. Our products face competition from companies integrating HDMI or MHL transmit functionality into SoCs, such as Broadcom, Intel, Qualcomm, TI, Nvidia, Marvell, ST Ericsson, Zoran, and MediaTek. We also compete in some instances against in-house semiconductor solutions designed by large consumer electronics OEMs.

In the PC market, Intel and other competitors such as AMD and Nvidia have integrated HDMI and/or DVI into their PC processor and chips sets. Our HDMI and DVI products also face competition from products based on the DisplayPort standard, which is a digital display interface standard being put forth by the Video Electronics Standards Association (VESA) that defines a digital audio/video interconnect intended to be used primarily between a computer and a display. DisplayPort is increasingly replacing DVI as the default standard for PC digital video interconnect technology.

Storage

Our SATA products compete with similar products from ACARD, Atmel, J-Micron, and Marvell. We also compete against AMD, Intel, nVidia, Silicon Integrated Systems, VIA Technologies and other motherboard chip-set makers, which have integrated SATA functionality into their chipsets.

Many of our competitors have longer operating histories and greater presence in key markets, greater name recognition, access to larger customer bases and significantly greater financial, engineering, intellectual property, sales and marketing, manufacturing, distribution, technical and other resources than we do. In particular, well-established semiconductor companies such as Analog Devices, Intel, National Semiconductor and Texas Instruments and consumer electronics manufacturers, such as Panasonic, Sony and Toshiba, may compete against us in the future. We cannot assure that we can compete successfully against current or potential competitors, or that competition will not seriously harm our business.

Employees

As of December 31, 2010, we had a total of 432 full-time employees, including 127 located outside of the United States. None of our employees are represented by a collective bargaining agreement. We have never experienced any work stoppages. We consider our relations with our employees to be good. We depend on the continued service of our key technical, sales and senior management personnel and our ability to attract and retain additional qualified personnel.

Item 1A. Risk Factors

A description of the risk factors associated with our business is set forth below. You should carefully consider the following risk factors, together with all other information contained or incorporated by reference in this filing, before you decide to purchase shares of our common stock. These factors could cause our future results to differ materially from those expressed in or implied by forward-looking statements made by us. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also harm our business. The trading price of our common stock could decline due to any of these risks and you may lose all or part of your investment.

Our success depends on demand for our new products.

Our future growth and success depends on our ability to develop and bring to market on a timely basis new products, such as our products supporting on the new Mobile High-Definition Link (MHL) standard. There can be no assurance that we will be successful in developing and marketing these new or other future products. Moreover, there is no assurance that our new or future products will achieve the desired level of market acceptance in the anticipated timeframes or that any such new or future products will contribute significantly to our revenue. Our new products face significant competition from established companies that have been selling competitive products for longer periods of time than we have. Our inability to develop and market new products could negatively affect our business and results of operations.

Our success depends on the development and introduction of new products, which we may not be able to do in a timely manner because the process of developing high-performance semiconductor products is complex and costly.

The development of new products is highly complex, and we have experienced delays, some of which exceeded one year, in the development and introduction of new products on several occasions in the past. We have recently introduced new products and will continue to introduce new products in the future. As our products integrate new, more advanced functions, they become more complex and increasingly difficult to design, manufacture and debug. Successful product development and introduction depends on a number of factors, including, but not limited to:

·	accurate prediction of market trends and requirements, the establishment and adoption of new standards in the market and the evolution of existing standards, including enhancements or modifications to existing standards such as HDMI, MHL, SPMT, DVI and SATA;

·	identification of customer and consumer market needs where we can apply our innovation and skills to create new standards or areas for product differentiation that improve our overall competitiveness either in an existing market or in a new market;

·	development of advanced technologies and capabilities and new products that satisfy customer and market requirements;

·	competitors’ and customers’ integration of the functionality of our products into their products, which puts pressure on us to continue to develop and introduce new products with new functionality;

·	timely completion and introduction of new product designs; correctly anticipating the market windows that will maximize acceptance of our products and then delivering the products to the markets within the required time frames;

·	management of product life cycles;

·	use of leading-edge foundry processes, when use of such processes is required and achievement of high manufacturing yields and low cost testing;

·	market acceptance of our new products;

·	consumer preferences for how they purchase and consume HD video are rapidly changing and our products may not be able to meet shifting consumer preferences; and

·	market acceptance of new architectures such as our input processors.

Accomplishing all of this is extremely challenging, time-consuming and expensive and there is no assurance that we will succeed. Product development delays may result from unanticipated engineering complexities, changing market or competitive product requirements or specifications, difficulties in overcoming resource constraints, the inability to license third-party technology or other factors. Competitors and customers may integrate the functionality of our products into their own products, thereby reducing demand for our products. If we are not able to develop and introduce our products successfully and in a timely manner, our costs could increase or our revenue could decrease, both of which would adversely affect our operating results. In addition, it is possible that we may experience delays in generating revenue from these products or that we may never generate revenue from these products. We must work with a semiconductor foundry and with potential customers to complete new product development and to validate manufacturing methods and processes to support volume production and potential re-work. Each of these steps may involve unanticipated difficulties, which could delay product introduction and reduce market acceptance of the product. In addition, these difficulties and the increasing complexity of our products may result in the introduction of products that contain defects or that do not perform as expected, which would harm our relationships with customers and our ability to achieve market acceptance of our new products. There can be no assurance that we will be able to achieve design wins for our planned new products, that we will be able to complete development of these products when anticipated, or that these products can be manufactured in commercial volumes at acceptable yields, or that any design wins will produce any revenue. Failure to develop and introduce new products, successfully and in a timely manner, may adversely affect our results of operations.

Our annual and quarterly operating results may fluctuate significantly and are difficult to predict, particularly given adverse domestic and global economic conditions.

Our annual and quarterly operating results are likely to vary significantly in the future based on a number of factors many of which we have little or no control. These factors include, but are not limited to:

·	the growth, evolution and rate of adoption of industry standards for our key markets, including consumer electronics, mobile, PCs and displays and storage devices and systems;

our licensing revenue is heavily dependent on a few key licensing transactions being completed for any given period, the timing of which is not always predictable and is especially susceptible to delay beyond the period in which completion is expected and our concentrated dependence on a few licensees in any period for substantial portions of our expected licensing revenue and profits;

·	our licensing revenue has been uneven and unpredictable over time and is expected to continue to be uneven and unpredictable for the foreseeable future, resulting in considerable fluctuation in the amount of revenue recognized in a particular quarter;

·	the impact of the results of the royalty compliance audits which we regularly perform;

competitive pressures, such as the ability of competitors to successfully introduce products that are more cost-effective or that offer greater functionality than our products, including integration into their products of functionality offered by our products, the prices set by competitors for their products and the potential for alliances, combinations, mergers and acquisitions among our competitors;

·	average selling prices of our products, which are influenced by competition and technological advancements, among other factors;

·	government regulations regarding the timing and extent to which digital content must be made available to consumers;

·	the availability of other semiconductors or other key components that are required to produce a complete solution for the customer; usually, we supply one of many necessary components;

·	the cost of components for our products, including the cost of gold, and prices charged by the third parties who manufacture, assemble and test our products; and

·	fluctuations in market demand, one-time sales opportunities and sales goals, sometimes result in heightened sales efforts during a given period that may adversely affect our sales in future periods.

Because we have little or no control over these factors and/or their magnitude, our operating results are difficult to predict. Any substantial adverse change in any of these factors could negatively affect our business and results of operations.

Our annual and quarterly operating results are highly dependent upon how well we manage our business.

Our annual and quarterly operating results are highly dependent upon and may fluctuate based on how well we manage our business. Some of these factors include the following:

·	our ability to manage product introductions and transitions, develop necessary sales and marketing channels and manage other matters necessary to enter new market segments;

·	our ability to successfully manage our business in multiple markets such as CE, PC, mobile and storage, which may involve additional research and development, marketing or other costs and expenses;

·	our ability to enter into licensing deals when expected and make timely deliverables and milestones on which recognition of revenue often depends;

·	our ability to engineer customer solutions that adhere to industry standards in a timely and cost-effective manner;

·	our ability to achieve acceptable manufacturing yields and develop automated test programs within a reasonable time frame for our new products;

·	our ability to manage joint ventures and projects, design services and our supply chain partners;

·	our ability to monitor the activities of our licensees to ensure compliance with license restrictions and remittance of royalties;

·	our ability to structure our organization to enable achievement of our operating objectives and to meet the needs of our customers and markets;

·	the success of the distribution and partner channels through which we choose to sell our products and our ability to manage expenses and inventory levels; and

our ability to successfully maintain certain structural and various compliance activities in support of our global structure which is designed to result in certain operational benefits as well as an overall lower tax rate and which, if not maintained, may result in us losing these operational and tax benefits.

If we fail to effectively manage our business, this could adversely affect our results of operations.

Our business has been and may continue to be significantly impacted by a deterioration in worldwide economic conditions and uncertainty in the outlook for the global economy makes it more likely that our actual results will differ materially from expectations.

Global credit and financial markets have experienced disruptions, and may continue to experience disruptions in the future, including diminished liquidity and credit availability, declines in consumer confidence, declines in economic growth, increases in unemployment rates, and continued uncertainty about economic stability. Despite signs of improvement, there can be no assurance that there will not be renewed deterioration in credit and financial markets and confidence in economic conditions. These economic uncertainties affect businesses such as ours in a number of ways, making it difficult to accurately forecast and plan our future business activities. The continued or further tightening of credit in financial markets may lead consumers and businesses to postpone spending, which may cause our customers to cancel, decrease or delay their existing and future orders with us. In addition, financial difficulties experienced by our suppliers or distributors could result in product delays, increased accounts receivable defaults and inventory challenges. The volatility in the credit markets has severely diminished liquidity and capital availability. Our CE product revenue, which comprised approximately 68.7%, 68.0% and 61.1% of total revenue for the years ended December 31, 2010, 2009 and 2008, respectively, is dependent on continued demand for consumer electronics, including but not limited to, DTVs, STBs, DVDs and game consoles. Demand for consumer electronics business is a function of the health of the economies in the United States and around the world. As a result of the recent recession experienced by the US economy and other economies around the world, the demand for overall consumer electronics has been and may continue to be adversely affected. As a result, the demand for our CE, PC and storage products and our operating results have been and may continue to be adversely affected as well. We cannot predict the timing, strength or duration of any economic disruption or subsequent economic recovery, worldwide, in the United States, in our industry, or in the consumer electronics market. These and other economic factors have had and may continue to have a material adverse effect on demand for our CE, PC and storage products and on our financial condition and operating results.

Investments in both fixed rate and floating rate interest earning instruments carry a degree of interest rate risk. Fixed rate debt securities may have their market value adversely impacted due to a rise in interest rates, while floating rate securities may produce less income than expected if interest rates fall. Due in part to these factors, our future investment income may fall short of expectations due to changes in interest rates. We may suffer losses in principal if we are forced to sell securities that decline in market value due to changes in interest rates. Recent adverse events in the global economy and in the credit markets could negatively impact our return on investment for these debt securities and thereby reduce the amount of cash and cash equivalents and investments on our balance sheet.

The licensing component of our business strategy increases business risk and volatility.

Part of our business strategy is to license IP through agreements with companies whereby companies incorporate our IP into their respective technologies that address markets in which we do not want to directly participate. There can be no assurance that additional companies will be interested in licensing our technology on commercially favorable terms or at all. We also cannot ensure that companies who license our technology will introduce and sell products incorporating our technology, will accurately report royalties owed to us, will pay agreed upon royalties, will honor agreed upon market restrictions, will not infringe upon or misappropriate our intellectual property and will maintain the confidentiality of our proprietary information. The IP agreements are complex and depend upon many factors including completion of milestones, allocation of values to delivered items and customer acceptances. Many of these factors require significant judgments. Licensing revenue could fluctuate significantly from period to period because it is heavily dependent on a few key deals being completed in a particular period, the timing of which is difficult to predict and may not match our expectations. Because of its high margin, the licensing revenue portion of our overall revenue can have a disproportionate impact on gross profit and profitability. Also, generating revenue from these arrangements is a lengthy and complex process that may last beyond the period in which efforts begin and, once an agreement is in place, the timing of revenue recognition may be dependent on customer acceptance of deliverables, achievement of milestones, our ability to track and report progress on contracts, customer commercialization of the licensed technology and other factors. Licensing that occurs in connection with actual or contemplated litigation is subject to risk that the adversarial nature of the transaction will induce non-compliance or non-payment. The accounting rules associated with recognizing revenue from these transactions are increasingly complex and subject to interpretation. Due to these factors, the amount of license revenue recognized in any period may differ significantly from our expectations.

We face intense competition in our markets, which may lead to reduced revenue from sales of our products and increased losses.

The CE, PC and storage markets in which we operate are intensely competitive. These markets are characterized by rapid technological change, evolving standards, short product life cycles and declining selling prices. We expect competition for many of our products to increase, as industry standards become widely adopted, as competitors reduce prices and offer products with greater levels of integration, and as new competitors enter our markets.

Our products face competition from companies selling similar discrete products and from companies selling products such as chipsets and system-on-a-chip (SoC) solutions with integrated functionality. Our competitors include semiconductor companies that focus on the CE, display or storage markets, as well as major diversified semiconductor companies and we expect that new competitors will enter our markets. Current or potential customers, including our own licensees, may also develop solutions that could compete with us, including solutions that integrate the functionality of our products into their solutions. In addition, current or potential OEM customers may have internal semiconductor capabilities and may develop their own solutions for use in their products rather than purchasing them from companies such as us. Some of our competitors have already established supplier or joint development relationships with current or potential customers and may be able to leverage their existing relationships to discourage these customers from purchasing products from us or persuade them to replace our products with theirs. Many of our competitors have longer operating histories, greater presence in key markets, better name recognition, access to larger customer bases and significantly greater financial, sales and marketing, manufacturing, distribution, technical and other resources than we do and as a result, they may be able to adapt more quickly to new or emerging technologies and customer requirements, or devote greater resources to the promotion and sale of their products. In particular, well-established semiconductor companies, such as Analog Devices, NXP, Broadcom, Intel, National Semiconductor and Texas Instruments and CE manufacturers, such as Panasonic, Sony, Samsung and Toshiba, may compete against us in the future. Some of our competitors could merge, which may enhance their market presence. Existing or new competitors may also develop technologies that more effectively address our markets with products that offer enhanced features and functionality, lower power requirements, greater levels of integration or lower cost. Increased competition has resulted in and is likely to continue to result in price reductions and loss of market share in certain markets. We cannot assure you that we can compete successfully against current or potential competitors, or that competition will not reduce our revenue and gross margins.

Table of Contents

We operate in rapidly evolving markets, which makes it difficult to evaluate our future prospects.

The markets in which we compete are characterized by rapid technological change, evolving customer needs and frequent introductions of new products and standards. As we adjust to evolving customer requirements and technological advances, we may be required to further reposition our existing offerings and to introduce new products and services. We may not be successful in developing and marketing such new offerings, or we may experience difficulties that could delay or prevent the development and marketing of such new offerings. Moreover, new standards that compete with standards that we promote have been and in the future may be introduced from time to time, which could impact our success. Accordingly, we face risks and difficulties frequently encountered by companies in new and rapidly evolving markets. If we do not successfully address these risks and difficulties, our results of operations could be negatively affected.

We may experience difficulties in transitioning to smaller geometry process technologies or in achieving higher levels of design integration, which may result in reduced manufacturing yields, delays in product deliveries and increased expenses.

To remain competitive, we expect to continue to transition our semiconductor products to increasingly smaller line width geometries. This transition requires us to modify the manufacturing processes for our products and to redesign some products as well as standard cells and other integrated circuit designs that we may use in multiple products. We periodically evaluate the benefits, on a product-by-product basis, of migrating to smaller geometry process technologies to reduce our costs. Currently most of our products are manufactured in .18 micron and .13 micron, geometry processes. We are now designing a new product in 65 nanometer process technology and planning for the transition to smaller process geometries. In the past, we have experienced some difficulties in shifting to smaller geometry process technologies or new manufacturing processes, which resulted in reduced manufacturing yields, delays in product deliveries and increased expenses. The transition to 65 nanometer geometry process technology will result in significantly higher mask and prototyping costs, as well as additional expenditures for engineering design tools and related computer hardware. We may face similar difficulties, delays and expenses as we continue to transition our products to smaller geometry processes.

We are dependent on our relationships with our foundry subcontractor to transition to smaller geometry processes successfully. We cannot assure you that the foundries that we use will be able to effectively manage the transition in a timely manner, or at all, or that we will be able to maintain our existing foundry relationships or develop new ones. If any of our foundry subcontractors or we experience significant delays in this transition or fail to efficiently implement this transition, we could experience reduced manufacturing yields, delays in product deliveries and increased expenses, all of which could harm our relationships with our customers and our results of operations.

We will have difficulty selling our products if customers do not design our products into their product offerings or if our customers’ product offerings are not commercially successful.

Our products are generally incorporated into our customers’ products at the customers’ design stage. As a result, we rely on manufacturers to select our products to be designed into their products. Without these “design wins,” it is very difficult to sell our products. We often incur significant expenditures on the development of a new product without any assurance that a manufacturer will select our product for design into its own product. Additionally, in some instances, we are dependent on third parties to obtain or provide information that we need to achieve a design win. Some of these third parties may be our competitors and, accordingly, may not supply this information to us on a timely basis, if at all. Once a manufacturer designs a competitor’s product into its product offering, it becomes significantly more difficult for us to sell our products to that customer because changing suppliers involves significant cost, time, effort and risk for the customer. Furthermore, even if a manufacturer designs one of our products into its product offering, we cannot be assured that its product will be commercially successful or that we will receive any revenue from that product. Sales of our products largely depend on the commercial success of our customers’ products. Our customers generally can choose at any time to stop using our products if their own products are not commercially successful or for any other reason. We cannot assure you that we will continue to achieve design wins or that our customers’ equipment incorporating our products will ever be commercially successful.

Our products typically have lengthy sales cycles. A customer may decide to cancel or change its product plans, which could cause us to lose anticipated sales. In addition, our average product life cycles tend to be short and, as a result, we may hold excess or obsolete inventory that could adversely affect our operating results.

After we have developed and delivered a product to a customer, the customer will usually test and evaluate our product prior to designing its own equipment to incorporate our product. Our customers generally need three months to over six months to test, evaluate and adopt our product and an additional three months to over nine months to begin volume production of products that incorporate our products. Due to this lengthy sales cycle, we may experience significant delays from the time we incur operating expenses and make investments in inventory until the time that we generate revenue from these products. It is possible that we may never generate any revenue from these products after incurring such expenditures. Even if a customer selects our product to incorporate into its products, we have no assurances that the customer will ultimately market and sell its products or that such efforts by our customer will be successful. The delays inherent in our lengthy sales cycle increase the risk that a customer will decide to cancel or change its product plans. Such a cancellation or change in plans by a customer could cause us to lose sales that we had anticipated. In addition, anticipated sales could be materially and adversely affected if a significant customer curtails, reduces or delays orders during our sales cycle or chooses not to release equipment that contains our products. Further, the combination of our lengthy sales cycles coupled with worldwide economic conditions could have a compounding negative impact on the results of our operations.

While our sales cycles are typically long, our average product life cycles tend to be short as a result of the rapidly changing technology environment in which we operate. As a result, the resources devoted to product sales and marketing may not generate material revenue for us and from time to time, we may need to write off excess and obsolete inventory. If we incur significant marketing expenses and investments in inventory in the future that if we are not able to recover and we are not able to compensate for those expenses, our operating results could be adversely affected. In addition, if we sell our products at reduced prices in anticipation of cost reductions but still hold higher cost products in inventory, our operating results would be harmed.

Table of Contents

Our customers may not purchase anticipated levels of products, which can result in excess inventories.

We generally do not obtain firm, long-term purchase commitments from our customers and, in order to accommodate the requirements of certain customers, we may from time to time build inventory that is specific to that customer in advance of receiving firm purchase orders. The short-term nature of our customers’ commitments and the rapid changes in demand for their products reduce our ability to accurately estimate the future requirements of those customers. Should the customer’s need shift so that they no longer require such inventory, we may be left with excessive inventories, which could adversely affect our operating results.

We depend on a few key customers and the loss of any of them could significantly reduce our revenue.

Historically, a relatively small number of customers and distributors have generated a significant portion of our revenue. For the year ended December 31, 2010, revenue from Samsung Electronics, Innotech Corporation and Microtek, Inc. accounted for 17.0%, 11.3% and 11.0% of our total revenue, respectively. For the year ended December 31, 2009, revenue from Microtek, Inc. and Weikeng Industrial accounted for 11.9% and 10.3% of our total revenue, respectively. For the year ended December 31, 2008, revenue from World Peace Industrial, Microtek, Inc., Weikeng Industrial and Innotech Corporation represented 14.6%, 11.8%, 11.5% and 10.5% of our total revenue, respectively. In addition, an end-customer may buy our products through multiple distributors, contract manufacturers and /or directly, which could create an even greater concentration. We cannot be certain that customers and key distributors that have accounted for significant revenue in past periods, individually or as a group, will continue to sell our products and generate revenue. As a result of this concentration of our customers, our results of operations could be negatively affected if any of the following occurs:

·	one or more of our customers, including distributors, becomes insolvent or goes out of business;

·	one or more of our key customers or distributors significantly reduces, delays or cancels orders; and/or

·	one or more significant customers selects products manufactured by one of our competitors for inclusion in their future product generations.

While our participation in multiple markets has broadened our customer base, as product mix fluctuates from quarter to quarter, we may become more dependent on a small number of customers or a single customer for a significant portion of our revenue in a particular quarter, the loss of which could adversely affect our operating results.

We sell our products through distributors, which limits our direct interaction with our end customers, therefore reducing our ability to forecast sales and increasing the complexity of our business.

Many original equipment manufacturers (“OEMs”) rely on third-party manufacturers or distributors to provide inventory management and purchasing functions. Distributors generated 61.1%, 59.2% and 52.1% of our revenue for the years ended December 31, 2010, 2009 and 2008, respectively. Selling through distributors reduces our ability to forecast sales and increases the complexity of our business, requiring us to:

·	manage a more complex supply chain;

·	monitor and manage the level of inventory of our products at each distributor;

·	estimate the impact of credits, return rights, price protection and unsold inventory at distributors; and

·	monitor the financial condition and credit-worthiness of our distributors, many of which are located outside of the United States and the majority of which are not publicly traded.

Since we have limited ability to forecast inventory levels at our end customers, it is possible that there may be significant build-up of inventories in the distributor channel, with the OEM or the OEM’s contract manufacturer. Such a buildup could result in a slowdown in orders, requests for returns from customers, or requests to move out planned shipments. This could adversely impact our revenues and profits.

Any failure to manage these challenges could disrupt or reduce sales of our products and unfavorably impact our financial results.

Governmental action against companies located in offshore jurisdictions may lead to a reduction in the demand for our common shares.

Recent federal and state legislation has been proposed, and additional legislation may be proposed in the future which, if enacted, could have an adverse tax impact on both us and our stockholders. For example, the ability to defer taxes as a result of permanent investments offshore could be limited, thus raising our effective tax rate.

Table of Contents

We have made acquisitions in the past and may make acquisitions in the future, and these acquisitions involve numerous risks.

Our growth depends upon market growth and our ability to enhance our existing products and introduce new products on a timely basis. Acquisition of companies or intangible assets is a strategy we may use to develop new products and enter new markets. We may acquire additional companies or technologies in the future. Acquisitions involve numerous risks, including, but not limited to, the following:

·	difficulty and increased costs in assimilating employees, including our possible inability to keep and retain key employees of the acquired business;

·	disruption of our ongoing business;

·	discovery of undisclosed liabilities of the acquired companies and legal disputes with founders or stockholders of acquired companies;

·	inability to commercialize acquired technology; and

·	the need to take impairment charges or write-downs with respect to acquired assets.

No assurance can be given that our prior acquisitions or our future acquisitions, if any, will be successful or provide the anticipated benefits, or that they will not adversely affect our business, operating results or financial condition. Failure to manage growth effectively and to successfully integrate acquisitions made by us could materially harm our business and operating results.

For example, in January 2007, we completed the acquisition of sci-worx, now Silicon Image, GmbH. In 2009, because of our decision to focus on discrete semiconductor products and related intellectual property, we decided to restructure our research and development operations resulting in the closure of our two sites in Germany.

Industry cycles may strain our management and resources.

Cycles of growth and contraction in our industry may strain our management and resources. To manage these industry cycles effectively, we must:

·	improve operational and financial systems;

·	train and manage our employee base;

·	successfully integrate operations and employees of businesses we acquire or have acquired;

·	attract, develop, motivate and retain qualified personnel with relevant experience; and

·	adjust spending levels according to prevailing market conditions.

If we cannot manage industry cycles effectively, our business could be seriously harmed.

The cyclical nature of the semiconductor industry may create constrictions in our foundry, test and assembly capacity.

The semiconductor industry is characterized by significant downturns and wide fluctuations in supply and demand. This cyclicality has led to significant fluctuations in product demand and in the foundry, test and assembly capacity of third-party suppliers. Production capacity for fabricated semiconductors is subject to allocation, whereby not all of our production requirements would be met. This may impact our ability to meet demand and could also increase our production costs and inventory levels. Cyclicality has also accelerated decreases in average selling prices per unit. We may experience fluctuations in our future financial results because of changes in industry-wide conditions. Our financial performance has been and may in the future be, negatively impacted by downturns in the semiconductor industry. In a downturn situation, we may incur substantial losses if there is excess production capacity or excess inventory levels in the distribution channel.

We depend on third-party sub-contractors to manufacture, assemble and test nearly all of our products, which reduce our control over the production process.

We do not own or operate a semiconductor fabrication facility. We rely on one third party semiconductor foundry overseas to produce substantially all of our semiconductor products. We also rely on outside assembly and test services to test all of our semiconductor products. Our reliance on independent foundries, assembly and test facilities involves a number of significant risks, including, but not limited to:

·	reduced control over delivery schedules, quality assurance, manufacturing yields and production costs;

·	lack of guaranteed production capacity or product supply, potentially resulting in higher inventory levels; and

·	lack of availability of, or delayed access to, next-generation or key process technologies.

We do not have a long-term supply agreement with any of our subcontractors and instead obtain production services on a purchase order basis. Our outside sub-contractors have no obligation to manufacture our products or supply products to us for any specific period of time, in any specific quantity or at any specific price, except as set forth in a particular purchase order. Our requirements represent a small portion of the total production capacity of our outside foundry, assembly and test facilities and our sub-contractors may reallocate capacity on short notice to other customers who may be larger and better financed than we are, or who have long-term agreements with our sub-contractors, even during periods of high demand for our products. This foundry may allocate or move production of our products to different foundries under their control, even in different locations, which may be time consuming, costly and difficult, have an adverse affect on quality, yields and costs and require us and/or our customers to re-qualify the products, which could open up design wins to competition and result in the loss of design wins and design-ins. If our subcontractors are unable or unwilling to continue manufacturing our products in the required volumes, at acceptable quality, yields and costs and in a timely manner, our business will be substantially harmed. As a result, we would have to identify and qualify substitute sub-contractors, which would be time-consuming, costly and difficult; there is no guarantee that we would be able to identify and qualify such substitute sub-contractors on a timely basis or obtain commercially reasonable terms from them. This qualification process may also require significant effort by our customers and may lead to re-qualification of parts, opening up design wins to competition and loss of design wins and design-ins. Any of these circumstances could substantially harm our business. In addition, if competition for foundry, assembly and test capacity increases, our product costs may increase and we may be required to pay significant amounts or make significant purchase commitments to secure access to production services.

The complex nature of our production process, which can reduce yields and prevent identification of problems until well into the production cycle or, in some cases, after the product has been shipped.

The manufacture of semiconductors is a complex process and it is often difficult for semiconductor foundries to achieve acceptable product yields. Product yields depend on both our product design and the manufacturing process technology unique to the semiconductor foundry. Since low yields may result from either design or process difficulties, identifying problems can often only occur well into the production cycle, when an actual product exists that can be analyzed and tested.

Further, we only test our products after they are assembled, as their high-speed nature makes earlier testing difficult and expensive. As a result, defects often are not discovered until after assembly. This could result in a substantial number of defective products being assembled and tested or shipped, thus lowering our yields and increasing our costs. These risks could result in product shortages or increased costs of assembling, testing or even replacing our products.

Although we test our products before shipment, they are complex and may contain defects and errors. In the past we have encountered defects and errors in our products. Because our products are sometimes integrated with products from other vendors, it can be difficult to identify the source of any particular problem. Delivery of products with defects or reliability, quality or compatibility problems, may damage our reputation and our ability to retain existing customers and attract new customers. In addition, product defects and errors could result in additional development costs, diversion of technical resources, delayed product shipments, increased product returns, warranty and product liability claims against us that may not be fully covered by insurance. Any of these circumstances could substantially harm our business.

We face foreign business, political and economic risks because a majority of our products and our customers’ products are manufactured and sold outside of the United States.

A substantial portion of our business is conducted outside of the United States. As a result, we are subject to foreign business, political and economic risks. Nearly all of our products are manufactured in Taiwan or elsewhere in Asia. For the years ended December 31, 2010, 2009 and 2008, approximately 78.9%, 79.4% and 83.4% of our total revenue respectively, was generated from customers and distributors located outside of United States, primarily in Asia. We anticipate that sales outside of the United States will continue to account for a substantial portion of our revenue in future periods. In addition, we undertake various sales and marketing activities through regional offices in several other countries and we have significantly expanded our research and development operations outside of the United States. We intend to continue to expand our international business activities. Accordingly, we are subject to international risks, including, but not limited to:

·	political, social and economic instability;

·	exposure to different business practices and legal standards, particularly with respect to intellectual property;

·	natural disasters and public health emergencies;

·	nationalization of business and blocking of cash flows;

·	trade and travel restrictions;

·	the imposition of governmental controls and restrictions;

·	burdens of complying with a variety of foreign laws;

·	import and export license requirements and restrictions of the United States and each other country in which we operate;

·	unexpected changes in regulatory requirements;

·	foreign technical standards;

·	changes in taxation and tariffs;

·	difficulties in staffing and managing international operations;

·	fluctuations in currency exchange rates;

·	difficulties in collecting receivables from foreign entities or delayed revenue recognition;

·	expense and difficulties in protecting our intellectual property in foreign jurisdictions;

·	exposure to possible litigation or claims in foreign jurisdictions; and,

·	potentially adverse tax consequences.

Any of the factors described above may have a material adverse effect on our ability to increase or maintain our foreign sales. In addition, original equipment manufacturers that design our semiconductors into their products sell them outside of the United States. This exposes us indirectly to foreign risks. Because sales of our products are denominated exclusively in United States dollars, relative increases in the value of the United States dollar will increase the foreign currency price equivalent of our products, which could lead to a change in the competitive nature of these products in the marketplace. This in turn could lead to a reduction in sales and profits.

We may have to invest more resources in research and development than anticipated, which could increase our operating expenses and negatively impact our operating results.

In 2009, as part of our plan to enhance our operational efficiency and to lower our overall cost structure, we decided to restructure our research and development operations resulting in the closure of our two R&D sites in Germany. As a result, we have transitioned certain of our R&D activities to new locations in Asia. As part of our current business model, we outsource certain of our R&D activities in response to certain peak resource requirements and on-going development activities. If we are unable to properly manage and effectively utilize these resources, they could have adverse effects on our business, financial condition and operating results.

Moreover, if new competitors, technological advances by existing competitors, our entry into new markets, or other competitive factors require us to invest significantly greater resources than anticipated in our research and development efforts, our operating expenses would increase. If we are required to invest significantly greater resources than anticipated in research and development efforts without a corresponding increase in revenue, our operating results could decline. Research and development expenses are likely to fluctuate from time to time to the extent we make periodic incremental investments in research and development and these investments may be independent of our level of revenue which could negatively impact our financial results. In order to remain competitive, we anticipate that we will continue to devote substantial resources to research and development, and we expect these expenses to increase in absolute dollars in the foreseeable future due to the increased complexity and the greater number of products under development.

The success of our business depends upon our ability to adequately protect our intellectual property.

We rely on a combination of patent, copyright, trademark, mask work and trade secret laws, as well as nondisclosure agreements and other methods, to protect our proprietary technologies. We have been issued patents and have a number of pending patent applications. However, we cannot assure you that any patents will be issued as a result of any applications or, if issued, that any claims allowed will protect our technology. In addition, we do not file patent applications on a worldwide basis, meaning we do not have patent protection in some jurisdictions. It may be possible for a third-party, including our licensees, to misappropriate our copyrighted material or trademarks. It is possible that existing or future patents may be challenged, invalidated or circumvented and effective patent, copyright, trademark and trade secret protection may be unavailable or limited in foreign countries. It may be possible for a third-party to copy or otherwise obtain and use our products or technology without authorization, develop similar technology independently or design around our patents in the United States and in other jurisdictions. It is also possible that some of our existing or new licensing relationships will enable other parties to use our intellectual property to compete against us. Legal actions to enforce intellectual property rights tend to be lengthy and expensive and the outcome often is not predictable. As a result, despite our efforts and expenses, we may be unable to prevent others from infringing upon or misappropriating our intellectual property, which could harm our business. In addition, practicality also limits our assertion of intellectual property rights. Patent litigation is expensive and its results are often unpredictable. Assertion of intellectual property rights often results in counterclaims for perceived violations of the defendant’s intellectual property rights and/or antitrust claims. Certain parties after receipt of an assertion of infringement will cut off all commercial relationships with the party making the assertion, thus making assertions against suppliers, customers and key business partners risky. If we forgo making such claims, we may run the risk of creating legal and equitable defenses for an infringer.

We generally enter into confidentiality agreements with our employees, consultants and strategic partners. We also try to control access to and distribution of our technologies, documentation and other proprietary information. Despite these efforts, internal or external parties may attempt to copy, disclose, obtain or use our products, services or technology without our authorization. Also, current or former employees may seek employment with our business partners, customers or competitors, and we cannot assure you that the confidential nature of our proprietary information will be maintained in the course of such future employment. Additionally, current, departing or former employees or third parties could attempt to penetrate our computer systems and networks to misappropriate our proprietary information and technology or interrupt our business. Because the techniques used by computer hackers and others to access or sabotage networks change frequently and generally are not recognized until launched against a target, we may be unable to anticipate, counter or ameliorate these techniques. As a result, our technologies and processes may be misappropriated, particularly in countries where laws may not protect our proprietary rights as fully as in the United States.

Our products may contain technology provided to us by other parties such as contractors, suppliers or customers. We may have little or no ability to determine in advance whether such technology infringes the intellectual property rights of a third party. Our contractors, suppliers and licensors may not be required to indemnify us in the event that a claim of infringement is asserted against us, or they may be required to indemnify us only up to a maximum amount, above which we would be responsible for any further costs or damages. In addition, we may have little or no ability to correct errors in the technology provided by such contractors, suppliers and licensors, or to continue to develop new generations of such technology. Accordingly, we may be dependent on their ability and willingness to do so. In the event of a problem with such technology, or in the event that our rights to use such technology become impaired, we may be unable to ship our products containing such technology, and may be unable to replace the technology with a suitable alternative within the time frame needed by our customers.

Our participation in working groups for the development and promotion of industry standards in our target markets, including the DVI and HDMI specifications, requires us to license some of our intellectual property for free or under specified terms and conditions, which may make it easier for others to compete with us in such markets.

A key element of our business strategy includes participating in working groups to establish industry standards in our target markets, promoting and enhancing specifications and developing and marketing products based on such specifications and future enhancements. We are a promoter of the Digital Display Working Group (DDWG), which published and promotes the DVI specification, and a founder in the working groups that develop and promote the HDMI specification and the MHL specification. In connection with our participation in such working groups:

·	we must license for free specific elements of our intellectual property to others for use in implementing the DVI specification; and we may license additional intellectual property for free as the DDWG promotes enhancements to the DVI specification;

·	we must license specific elements of our intellectual property to others for use in implementing the HDMI specification and we may license additional intellectual property as the HDMI founders group promotes enhancements to the HDMI specification; and

we must agree not to assert certain necessary patent claims against other members of the MHL consortium who may infringe such claims in implementing the MHL specification and this non-assert obligation may cover more of our patent portfolio as the MHL promoter group promotes enhancements to the MHL specification.

Accordingly, certain companies that implement the DVI, HDMI and MHL specifications in their products can use specific elements of our intellectual property to compete with us, in certain cases, for free. Although in the case of the HDMI and MHL specifications, there are annual fees and royalties associated with the adopters’ agreements, there can be no assurance that our shares of such annual fees and royalties will adequately compensate us for having to license or refrain from asserting our intellectual property.

Through our wholly-owned subsidiary, HDMI Licensing, LLC, we act as agent of the HDMI specification and are responsible for promoting and administering the specification. We receive all the license fees paid by adopters of the HDMI specification to cover the costs we incur to promote and administer the HDMI specification. There can be no assurance that, going forward, we will continue to act as agent of the HDMI specification and/or receive all the license fees paid by HDMI adopters. After an initial period during which we received all of the royalties paid by HDMI adopters, in 2007, the HDMI founders reallocated the royalties to reflect each founder’s relative contribution of intellectual property to the HDMI specification, and following this reallocation, our portion of HDMI royalties was reduced to approximately 62%. In 2010, HDMI founders again reviewed the allocation of HDMI royalties and agreed on an allocation formula that further reduced the portion of HDMI royalties received by us effective January 2011. Further, we expect that HDMI founders will continue to review the allocation of HDMI royalties from time to time and there can be no assurance regarding the portion of HDMI royalties received by us in the future.

Through our wholly-owned subsidiary, MHL, LLC, we act as agent of the MHL specification and are responsible for promoting and administering the specification. As agent, we are entitled to receive license fees paid by adopters of the MHL specification sufficient to reimburse us the costs we incur to promote and administer the specification. Given the limited number of MHL adopters to date, we do not believe that the license fees paid by such adopters will be sufficient to reimburse us for these costs and there can be no assurance that the license fees paid by MHL adopters will ever be sufficient to reimburse us the cost we incur as agent of the specification.

We intend to promote and continue to be involved and actively participate in other standard setting initiatives. For example, we also recently joined the Serial Port Memory Technology Working Group (SPMTWG) to develop and promote a new memory technology. Accordingly, we may license additional elements of our intellectual property to others for use in implementing, developing, promoting or adopting standards in our target markets, in certain circumstances at little or no cost. This may make it easier for others to compete with us in such markets. In addition, even if we receive license fees and/or royalties in connection with the licensing of our intellectual property, there can be no assurance that such license fees and/or royalties will adequately compensate us for having to license our intellectual property.

Our success depends in part on our relationships with strategic partners and use of technologies.

We have entered into and expect to continue to enter into strategic partnerships with third parties. Negotiating and performing under these strategic partnerships involves significant time and expense; we may not realize anticipated increases in revenue, standards adoption or cost savings; and these strategic partnerships may make it easier for the third parties to compete with us; any of which may have a negative effect our business and results of operations.

Strategic partnerships that we enter into with third parties may not result in the anticipated results. For example, in February 2007, we entered into a licensing agreement with Sunplus Technology Co., Ltd. (Sunplus), which granted us the rights to use and further develop advanced IP technology. Previously, we believed that the IP licensed under this agreement enhanced our ability to develop DTV technology and other related consumer product offerings. Based on the Company’s product strategy as of October 2009, we realized the IP obtained through the Sunplus agreement did not align with our product roadmap and during October 2009, we decided to write off our investment in Sunplus IP. This decision was prompted by a change in our product strategy due to market place and related competitive dynamics.

Our business may be impacted as a result of the adoption of competing standards and technologies by the broader market.

The success of our business has been significantly related to our participation in standard setting organizations. From time to time, competing standards have been established which negatively impact the success of existing standards or jeopardize the creation of a new standard. DisplayPort is an example of a competing standard on a different technology base which has created an alternative high definition connectivity methodology in the PC space. This standard has been adopted by several large PC manufactures. While currently not as widely recognized as the HDMI standard, DisplayPort does represent a viable alternative to the HDMI or MHL standards. If DisplayPort should gain broader adoption, our HDMI or MHL businesses could be negatively impacted and our revenues could be reduced.

Our business is dependent on the continued adoption and widespread implementation of the HDMI™ specification.

Our success is largely dependent upon the continued adoption and widespread implementation of the HDMI specification. More than 75% of our revenue is derived from the sale of HDMI enabled products and the licensing of our HDMI technology. Our leadership in the market for HDMI-enabled products and intellectual property has been based on our ability to introduce first-to-market semiconductor and IP solutions to our customers and to continue to innovate within the standard. Therefore, our inability to be first to market with our HDMI enabled products and intellectual property or to continue to drive innovation in the HDMI specification could have an adverse impact on our business going forward. In addition, the establishment and adoption by the markets we sell into of a competing digital interconnect technology could have an adverse impact on our ability to sell our products and license our intellectual property and therefore our revenues and business.

As the agent for the HDMI specification, we derive revenue from the license fees paid by adopters, and as a founder we derive revenue from the royalties paid by the adopters of the HDMI technology. Any development that has the effect of lowering the number of adopters of the HDMI standard will negatively impact these license fees and royalties. Also, when the HDMI consortium was first formed, we received 100% of the royalties collected from HDMI adopters. During 2007, the founders agreed to share the HDMI adopter’s royalty revenues among the various founders, such that we no longer receive all of the royalties, and in 2010, the HDMI founders agreed upon a royalty allocation formula that reduced our share of HDMI royalties effective January 2011. The allocation of license fees and royalty revenue among the HDMI founders is an issue that is reviewed and discussed by the founders from time to time. There can be no assurance that going forward we will continue to act as agent of the HDMI specification or to receive the share of HDMI license fees and royalties that we currently receive. If our share of these license fees and royalties is reduced, this decision will have a negative impact on our revenues. Refer to the previously discussed risk factor above which also discusses the sharing of HDMI royalty revenues amoung various founders.

Our success depends on managing our relationship with Intel.

Intel has a dominant role in many of the markets in which we compete, such as PC and storage and is a growing presence in the CE market. We have a multi-faceted relationship with Intel that is complex and requires significant management attention, including:

·	Intel and Silicon Image have been parties to business cooperation agreements;

·	Intel and Silicon Image are parties to a patent cross-license;

·	Intel and Silicon Image worked together to develop HDCP;

·	an Intel subsidiary has the exclusive right to license HDCP, of which we are a licensee;

·	Intel and Silicon Image were two of the promoters of the DDWG;

·	Intel is a promoter of the SATA working group, of which we are a contributor;

·	Intel is a supplier to us and a customer for our products;

·	we believe that Intel has the market presence to drive adoption of SATA by making it widely available in its chipsets and motherboards, which could affect demand for our products;

·	we believe that Intel has the market presence to affect adoption of HDMI by either endorsing complementary technology or promulgating a competing standard, which could affect demand for our products;

·	Intel may potentially integrate the functionality of our products, including SATA, DVI, or HDMI into its own chips and chipsets, thereby displacing demand for some of our products;

·	Intel may design new technologies that would require us to re-design our products for compatibility, thus increasing our R&D expense and reducing our revenue;

·	Intel’s technology, including its 845G and later chipsets, may lower barriers to entry for other parties who may enter the market and compete with us; and

·	Intel may enter into or continue relationships with our competitors that can put us at a relative disadvantage.

Our cooperation and competition with Intel can lead to positive benefits, if managed effectively. If our relationship with Intel is not managed effectively, it could seriously harm our business, negatively affect our revenue and increase our operating expenses.

New Releases of Microsoft Windows® and Apple Mac OS® operating systems may render our chips inoperable

ICs targeted to PC, laptop, or netbook designs (whether running Microsoft Windows ®, Apple Mac OS® or Linux operating systems) often require device driver software to operate. This software is difficult to produce and requires various certifications such as Microsoft’s Windows Hardware Quality Labs (WHQL) before being released. Each new revision of an operating system may require a new software driver and associated testing/certification. Failure to produce this software can have a negative impact on our relation with Microsoft and/or Apple and may damage our reputation as a quality supplier of SATA and HDMI products in the eyes of end consumers.

We have granted Intel rights with respect to our intellectual property, which could allow Intel to develop products that compete with ours or otherwise reduce the value of our intellectual property.

We entered into a patent cross-license agreement with Intel in which each of us granted the other a license to use the patents filed by the grantor prior to a specified date, except for identified types of products. We believe that the scope of our license to Intel excludes our current products and anticipated future products. Intel could, however, exercise its rights under this agreement to use our patents to develop and market other products that compete with ours, without payment to us. Additionally, Intel’s rights to our patents could reduce the value of our patents to any third-party who otherwise might be interested in acquiring rights to use our patents in such products. Finally, Intel could endorse competing products, including a competing digital interface, or develop its own proprietary digital interface. Any of these actions could substantially harm our business and results of operations.

We may become engaged in additional intellectual property litigation that could be time-consuming, may be expensive to prosecute or defend and could adversely affect our ability to sell our product.

In recent years, there has been significant litigation in the United States and in other jurisdictions involving patents and other intellectual property rights. This litigation is particularly prevalent in the semiconductor industry, in which a number of companies aggressively use their patent portfolios to bring infringement claims. In addition, in recent years, there has been an increase in the filing of so-called “nuisance suits,” alleging infringement of intellectual property rights. These claims may be asserted as counterclaims in response to claims made by a company alleging infringement of intellectual property rights. These suits pressure defendants into entering settlement arrangements to quickly dispose of such suits, regardless of merit. In addition, as is common in the semiconductor industry, from time to time we have been notified that we may be infringing certain patents or other intellectual property rights of others. Responding to such claims, regardless of their merit, can be time consuming, result in costly litigation, divert management’s attention and resources and cause us to incur significant expenses. As each claim is evaluated, we may consider the desirability of entering into settlement or licensing agreements. No assurance can be given that settlements will occur or that licenses can be obtained on acceptable terms or that litigation will not occur. In the event there is a temporary or permanent injunction entered prohibiting us from marketing or selling certain of our products, or a successful claim of infringement against us requiring us to pay damages or royalties to a third-party and we fail to develop or license a substitute technology, our business, results of operations or financial condition could be materially adversely affected.

Any potential intellectual property litigation against us or in which we become involved may be expensive and time-consuming and may divert our resources and the attention of our executives. It could also force us to do one or more of the following:

·	stop selling products or using technology that contains the allegedly infringing intellectual property;

·	attempt to obtain a license to the relevant intellectual property, which license may not be available on reasonable terms or at all; and

·	attempt to redesign products that contain the allegedly infringing intellectual property.

If we take any of these actions, we may be unable to manufacture and sell our products. We may be exposed to liability for monetary damages, the extent of which would be very difficult to accurately predict. In addition, we may be exposed to customer claims, for potential indemnity obligations and to customer dissatisfaction and a discontinuance of purchases of our products while the litigation is pending. Any of these consequences could substantially harm our business and results of operations.

We have entered into and may again be required to enter into, patent or other intellectual property cross-licenses.

Many companies have significant patent portfolios or key specific patents, or other intellectual property in areas in which we compete. Many of these companies appear to have policies of imposing cross-licenses on other participants in their markets, which may include areas in which we compete. As a result, we have been required, either under pressure of litigation or by significant vendors or customers, to enter into cross licenses or non-assertion agreements relating to patents or other intellectual property. This permits the cross-licensee, or beneficiary of a non-assertion agreement, to use certain or all of our patents and/or certain other intellectual property for free to compete with us. Our results of operations could be adversely affected by the use of cross-licensee or beneficiary of a non-assertion agreement of all our patents and/or certain other intellectual property.

We indemnify certain of our licensing customers against infringement.

We indemnify certain of our licensing agreements customers for any expenses or liabilities resulting from third-party claims of infringements of patent, trademark, trade secret, or copyright rights by the technology we license. Certain of these indemnification provisions are perpetual from execution of the agreement and, in some instances; the maximum amount of potential future indemnification is not limited. To date, we have not paid any such claims or been required to defend any lawsuits with respect to any claim. In the event that we were required to defend any lawsuits with respect to our indemnification obligations, or to pay any claim, our results of operations could be materially adversely affected.

We must attract and retain qualified personnel to be successful and competition for qualified personnel is increasing in our market.

Our success depends to a significant extent upon the continued contributions of our key management, technical and sales personnel, many of who would be difficult to replace. The loss of one or more of these employees could harm our business. Although we have entered into a limited number of employment contracts with certain executive officers, we generally do not have employment contracts with our key employees. Our success also depends on our ability to identify, attract and retain qualified technical, sales, marketing, finance and managerial personnel. Competition for qualified personnel is particularly intense in our industry and in our location. This makes it difficult to retain our key personnel and to recruit highly qualified personnel. We have experienced and may continue to experience, difficulty in hiring and retaining candidates with appropriate qualifications. To be successful, we need to hire candidates with appropriate qualifications and retain our key executives and employees. Replacing departing executive officers and key employees can involve organizational disruption and uncertain timing.

The volatility of our stock price has had an impact on our ability to offer competitive equity-based incentives to current and prospective employees, thereby affecting our ability to attract and retain highly qualified technical personnel. If these adverse conditions continue, we may not be able to hire or retain highly qualified employees in the future and this could harm our business. In addition, regulations adopted by The NASDAQ Stock Market requiring shareholder approval for all stock option plans, as well as regulations adopted by the New York Stock Exchange prohibiting NYSE member organizations from giving a proxy to vote on equity compensation plans unless the beneficial owner of the shares has given voting instructions, could make it more difficult for us to grant options to employees in the future. In addition, FASB ASC No. 718-10, Stock Compensation, requires us to record compensation expense for options granted to employees. To the extent that new regulations make it more difficult or expensive to grant options to employees, we may incur increased cash compensation costs or find it difficult to attract, retain and motivate employees, either of which could harm our business.

If our internal control over financial reporting or disclosure controls and procedures are not effective, there may be errors in our financial statements that could require restatement or our filings may not be timely and investors may lose confidence in our reported financial information, which could lead to a decline in our stock price. While we have not identified any material weaknesses in the past three years, we cannot assure you that a material weakness will not be identified in the future.

Section 404 of the Sarbanes-Oxley Act of 2002 requires us to evaluate the effectiveness of our internal control over financial reporting as of the end of each year and to include a management report assessing the effectiveness of our internal control over financial reporting in each Annual Report on Form 10-K. Section 404 also requires our independent registered public accounting firm to report on, our internal control over financial reporting.

Our management, including our Chief Executive Officer and Chief Financial Officer, does not expect that our internal control over financial reporting will prevent all error and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. Further, the design of a control system must reflect the fact that there are resource constraints and the benefits of controls must be considered relative to their costs. Controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the controls. Over time, controls may become inadequate because changes in conditions or deterioration in the degree of compliance with policies or procedures may occur. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

As a result, we cannot assure you that significant deficiencies or material weaknesses in our internal control over financial reporting will not be identified in the future. Any failure to maintain or implement required new or improved controls, or any difficulties we encounter in their implementation, could result in significant deficiencies or material weaknesses, cause us to fail to timely meet our periodic reporting obligations, or result in material misstatements in our financial statements. Any such failure could also adversely affect the results of periodic management evaluations and annual auditor attestation reports regarding disclosure controls and the effectiveness of our internal control over financial reporting required under Section 404 of the Sarbanes-Oxley Act of 2002 and the rules promulgated thereunder. The existence of a material weakness could result in errors in our financial statements that could result in a restatement of financial statements, cause us to fail to timely meet our reporting obligations and cause investors to lose confidence in our reported financial information, leading to a decline in our stock price.

We have experienced transitions in our management team, our board of directors in the past and may continue to do so in the future, which could result in disruptions in our operations and require additional costs.

We have experienced a number of transitions with respect to our board of directors and executive officers in recent quarters, including the following:

·	In December 2008, Dale Zimmerman resigned from his position as vice president of worldwide marketing.

·	In March 2009, Paul Dal Santo resigned from his position as chief operating officer.

·	In September 2009, Steve Tirado resigned from his positions as chief executive officer and director and Hal Covert was appointed as president and chief operating officer.

·	In January 2010, Camillo Martino was appointed as chief executive officer and director.

In January 2010, Harold Covert, who was appointed president and chief operating officer on September 25, 2009 while we undertook a search for a new chief executive officer, agreed to continue in his capacity as our president (but to no longer serve as chief financial officer or chief operating officer) during a transitional period from January 6, 2010 through September 30, 2010. On January 5, 2010, our Board of Directors also elected Mr. Covert to the Board, effective January 15, 2010 and through September 30, 2010.

·	In March 2010, J. Duane Northcutt resigned from his position as chief technology officer.

·	In March 2010, Tim Vehling, former vice president of worldwide marketing, was appointed as vice president of the products business group and Eric Almgren, former vice president of business development and IP licensing, was appointed as vice president of the IP business group.

·	In April 2010, Noland Granberry was appointed as our chief financial officer.

·	In April 2010, Sal Cobar resigned from his position as vice president of worldwide sales.

·	In September 2010, Harold Covert resigned from his positions as president and director.

Any future transitions may result in disruptions in our operations and require additional costs.

We have been and may continue to become the target of securities class action suits and derivative suits which could result in substantial costs and divert management attention and resources.

Securities class action suits and derivative suits are often brought against companies, particularly technology companies, following periods of volatility in the market price of their securities. Defending against these suits, even if meritless, can result in substantial costs to us and could divert the attention of our management.

Our operations and the operations of our significant customers, third-party wafer foundries and third-party assembly and test subcontractors are located in are as susceptible to natural disasters.

Our operations are headquartered in the San Francisco Bay Area, which is susceptible to earthquakes. TSMC, the outside foundry that produces the majority of our semiconductor products, is located in Taiwan. Siliconware Precision Industries Co. Ltd., or SPIL, Advanced Semiconductor Engineering, or ASE, and Amkor Taiwan are subcontractors located in Taiwan that assemble and test our semiconductor products. For the years ended December 31, 2010, 2009 and 2008 customers and distributors located in Japan generated 29.9%, 27.1% and 24.0%,of our revenue, respectively, and customers and distributors located in Taiwan generated 22.5%, 25.2% and 19.8% of our revenue, respectively. Both Taiwan and Japan are susceptible to earthquakes, typhoons and other natural disasters.

Our business, including a potential reduction of revenues, would be negatively affected if any of the following occurred:

·	an earthquake or other disaster in the San Francisco Bay Area or the Los Angeles area damaged our facilities or disrupted the supply of water or electricity to our headquarters;

·	an earthquake, typhoon or other disaster in Taiwan or Japan resulted in shortages of water, electricity or transportation, limiting the production capacity of our outside foundries or the ability of ASE to provide assembly and test services;

·	an earthquake, typhoon or other disaster in Taiwan or Japan damaged the facilities or equipment of our customers and distributors, resulting in reduced purchases of our products; or

an earthquake, typhoon or other disaster in Taiwan or Japan disrupted the operations of suppliers to our Taiwanese or Japanese customers, outside foundries or ASE, which in turn disrupted the operations of these customers, foundries or ASE and resulted in reduced purchases of our products or shortages in our product supply.

Terrorist attacks or war could lead to economic instability and adversely affect our operations, results of operations and stock price.

The United States has taken and continues to take, military action against terrorism and currently has troops in Iraq and in Afghanistan. In addition, the current tensions regarding nuclear arms in North Korea and Iran could escalate into armed hostilities or war. Acts of terrorism or armed hostilities may disrupt or result in instability in the general economy and financial markets and in consumer demand for the OEM’s products that incorporate our products. Disruptions and instability in the general economy could reduce demand for our products or disrupt the operations of our customers, suppliers, distributors and contractors, many of whom are located in Asia, which would in turn adversely affect our operations and results of operations. Disruptions and instability in financial markets could adversely affect our stock price. Armed hostilities or war in South Korea could disrupt the operations of the research and development contractors we utilize there, which would adversely affect our research and development capabilities and ability to timely develop and introduce new products and product improvements.

Changes in environmental rules and regulations could increase our costs and reduce our revenue.

Several jurisdictions have implemented rules that would require that certain products, including semiconductors, be made “green,” which means that the products need to be lead free and be free of certain banned substances. All of our products are available to customers in a green format. While we believe that we are generally in compliance with existing regulations, such environmental regulations are subject to change and the jurisdictions may impose additional regulations which could require us to incur costs to develop replacement products. These changes will require us to incur cost or may take time or may not always be economically or technically feasible, or may require disposal of non-compliant inventory. In addition, any requirement to dispose or abate previously sold products would require us to incur the costs of setting up and implementing such a program.

Provisions of our charter documents and Delaware law could prevent or delay a change in control and may reduce the market price of our common stock.

Provisions of our certificate of incorporation and bylaws may discourage, delay or prevent a merger or acquisition that a stockholder may consider favorable. These provisions include:

·	authorizing the issuance of preferred stock without stockholder approval;

·	providing for a classified board of directors with staggered, three-year terms;

·	requiring advance notice of stockholder nominations for the board of directors;

·	providing the board of directors the opportunity to expand the number of directors without notice to stockholders;

·	prohibiting cumulative voting in the election of directors;

·	requiring super-majority voting to amend some provisions of our certificate of incorporation and bylaws;

·	limiting the persons who may call special meetings of stockholders; and

·	prohibiting stockholder actions by written consent.

Provisions of Delaware law also may discourage, delay or prevent someone from acquiring or merging with us.

The price of our stock fluctuates substantially and may continue to do so.

The stock market has experienced extreme price and volume fluctuations that have affected the market valuation of many technology companies, including Silicon Image. These factors, as well as general economic and political conditions, may materially and adversely affect the market price of our common stock in the future. The market price of our common stock has fluctuated significantly and may continue to fluctuate in response to a number of factors, including, but not limited to:

·	actual or anticipated changes in our operating results;

·	changes in expectations of our future financial performance;

·	changes in market valuations of comparable companies in our markets;

·	changes in market valuations or expectations of future financial performance of our vendors or customers;

·	changes in our key executives and technical personnel; and

·	announcements by us or our competitors of significant technical innovations, design wins, contracts, standards or acquisitions.

Due to these factors, the price of our stock may decline. In addition, the stock market experiences volatility that is often unrelated to the performance of particular companies. These market fluctuations may cause our stock price to decline regardless of our performance.

Item 2. Properties

Our current headquarters, consisting of approximately 126,686 square feet of space in Sunnyvale, California, is leased through July 31, 2011, of which we ceased to use a total of 33,766 square feet in 2009 and 2010. We have approximately 6,899 square feet of space in Irvine, California that is being leased through November 30, 2012, which we ceased to use in 2009 and 25,227 square feet of space in two locations in China, which are being leased through July 23, 2011 and June 30, 2012. These facilities house our corporate offices, the majority of our engineering team, as well as a portion of our sales, marketing, operations and corporate services organizations.

We also lease facilities in Japan, Korea, and Taiwan. We believe that our existing properties are in good condition and suitable for the conduct of our business.

On January 6, 2011, we entered into a seven-year lease agreement (the “Lease”) with Christensen Holdings, L.P., a California limited partnership. Pursuant to the Lease, we are leasing an office building in Sunnyvale, California consisting of approximately 128,154 square feet, together with the non-exclusive right to use parking facilities and other amenities. This new office building will house our new corporate headquarters, which we expect to begin occupying in June 2011, just prior to the expiration of the lease agreement for our current headquarters in July 2011.

PART II

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

Our common shares have been traded on the NASDAQ Stock Market since our initial public offering on October 6, 1999. Our common shares trade under the symbol “SIMG”. Our shares are not listed on any other markets or exchanges. The following table shows the high and low closing prices for our common shares as reported by the NASDAQ Stock Market:

	High		Low
2010
Fourth Quarter	$	8.11	$	4.51
Third Quarter		4.93		3.12
Second Quarter		3.97		3.00
First Quarter	$	3.15	$	2.29

2009
Fourth Quarter	$	2.70	$	2.11
Third Quarter		3.39		2.23
Second Quarter		3.19		2.17
First Quarter	$	4.44	$	2.04

As of January 31, 2011, we had approximately 84 holders of record of our common stock and the closing price of our common stock was $6.86. Because many of such shares are held by brokers and other institutions on behalf of stockholders, we are unable to estimate the total number of stockholders represented by these record holders.

We have never declared or paid cash dividends on shares of our capital stock. We intend to retain any future earnings to finance growth and do not anticipate paying cash dividends.

In February 2007, our Board of Directors authorized a stock repurchase program under which we were authorized to purchase up to $100.0 million of common stock, on the open market, or in negotiated or block transactions, over a 36 month period. As of December 31, 2007, we had repurchased a total of 5.0 million shares at a total cost of $38.1 million. In February 2008, our Board of Directors authorized an additional $100.0 million stock repurchase program, under which shares may be repurchased over a period of three years, to commence following completion of our accelerated stock repurchase plan (“ASR”) (see below). Purchases under this program may be increased, decreased or discontinued at any time without prior notice.

In February 2008, we entered into an ASR with Credit Suisse International (Credit Suisse), to purchase shares of common stock for an aggregate purchase price of approximately $62.0 million paid in February 2008. We received 11.5 million shares under the agreement, based on a predetermined price, which was subject to an adjustment based on the volume weighted average price during the term of the ASR. In accordance with the ASR agreement, on June 25, 2008, we chose to settle the arrangement in cash (rather than shares) and made a final payment of approximately $6.2 million for the purchase of shares. The ASR terminated on June 30, 2008 with final settlement taking place in July 2008 (“settlement date”). On the settlement date, Credit Suisse returned approximately $1.0 million based on the volume weighted average share price during the period. In accordance with the relevant accounting guidance, we reflected the 11.5 million shares repurchased and the $68.2 million paid to Credit Suisse as treasury stock and recorded the $1.0 million received as part of other income in the consolidated statement of income in the second and third quarters of 2008.

With the repurchase, we completed our original stock repurchase program announced on February 2007 and repurchased approximately $5.0 million of our stock under the new $100.0 million stock repurchase program approved by the Board of Directors in February 2008.

Critical Accounting Policies

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect amounts reported in our consolidated financial statements and accompanying notes. We base our estimates on historical experience and all known facts and circumstances that we believe are relevant. Actual results may differ materially from our estimates. We believe the accounting policies discussed below to be most critical to an understanding of our financial condition and results of operations because they require us to make estimates, assumptions and judgments about matters that are inherently uncertain.

Revenue Recognition

We recognize revenue when persuasive evidence of an arrangement exists, delivery or performance has occurred, the sales price is fixed or determinable and collectability is reasonably assured.

Revenue from products sold directly to end-users, or to distributors that are not entitled to price concessions and rights of return, is generally recognized when title and risk of loss has passed to the buyer which typically occurs upon shipment. All shipping costs are charged to cost of product revenue.

Revenue from products sold to distributors with agreements allowing for stock rotations is generally recognized upon shipment. Reserves for stock rotations are estimated based primarily on historical experience and provided for at the time of shipment.

For products sold to distributors with agreements allowing for price concessions and stock rotation rights/product returns, we recognize revenue based on when the distributor reports that it has sold the product to its customer. Our recognition of such distributor sell-through is based on point of sales reports received from the distributor which establishes a customer, quantity and final price. Revenue is not recognized upon our shipment of the product to the distributor, since, due to certain forms of price concessions, the sales price is not substantially fixed or determinable at the time of shipment. Price concessions are recorded when incurred, which is generally at the time the distributor sells the product to its customer. Additionally, these distributors have stock rotation rights permitting them to return products to us, up to a specified amount for a given period of time. When the distributor reports that it has sold product to its customer, our sales price to the distributor is fixed. Once we receive the point of sales reports from the distributor, it has satisfied all the requirements for revenue recognition with respect to the product reported as sold and any product returns/stock rotation and price concession rights that the distributor has under its distributor agreement with us lapsed at that time. Pursuant to our distributor agreements, older, end-of-life and certain other products are generally sold with no right of return and are not eligible for price concessions. For these products, revenue is recognized upon shipment and title transfer assuming all other revenue recognition criteria are met.

At the time of shipment to distributors, we record a trade receivable for the selling price since there is a legally enforceable right to payment, we relieve inventory for the carrying value of goods shipped since legal title has passed to the distributor and until revenue is recognized, we record the gross margin in “deferred margin on sale to distributors,” a component of current liabilities in our consolidated balance sheet. Deferred margin on the sale to distributor effectively represents the gross margin on the sale to the distributor. However, the amount of gross margin we recognize in future periods will be less than the originally recorded deferred margin on sales to distributor as a result of negotiated price concessions. We sell each item in our product price book to all of our distributors worldwide at a relatively uniform list price. However, distributors resell our products to end customers at a very broad range of individually negotiated price points based on customer, product, quantity, geography, competitive pricing and other factors. The majority of our distributors’ resales are priced at a discount from the list price. Often, under these circumstances, we remit back to the distributor a portion of their original purchase price after the resale transaction is completed. Thus, a portion of the “deferred margin on the sale to distributor” balance represents a portion of distributors’ original purchase price that will be remitted back to the distributor in the future. The wide range and variability of negotiated price concessions granted to the distributors does not allow us to accurately estimate the portion of the balance in the deferred margin on the sale to distributors that will be remitted back to the distributors. In addition to the above, we also reduce the deferred margin by anticipated or determinable future price protections based on revised price lists, if any.

Table of Contents

We derive revenue from the license of our internally developed intellectual property (IP). We enter into IP licensing agreements that generally provide licensees the right to incorporate our IP components in their products with terms and conditions that vary by licensee. Revenue earned under contracts with our licensees is classified as licensing revenue. Our license fee arrangements generally include multiple deliverables and for multiple deliverable arrangements, we follow the guidance in Financial Accounting Standards Board (“FASB”) Accounting Standard Codification (“ASC”) No. 605-25-25, Multiple-Element Arrangements Revenue Recognition, to determine whether there is more than one unit of accounting. To the extent that the deliverables are separable into multiple units of accounting, we allocate the total fee on such arrangements to the individual units of accounting using the residual method, if objective and reliable evidence of fair value does not exist for delivered elements. We then recognize revenue for each unit of accounting depending on the nature of the deliverable(s) comprising the unit of accounting in accordance with the revenue recognition criteria mentioned above.

The IP licensing agreements generally include a nonexclusive license for the underlying IP. Fees under these agreements generally include (a) license fees relating to our IP, (b) support, typically for one year; and (c) royalties payable following the sale by our licensees of products incorporating the licensed technology. The license for our IP has standalone value and can be used by the licensee without support. Further, objective and reliable evidence of fair value exists for support. Accordingly, license and support fees are each treated as separate units of accounting.

Certain licensing agreements provide for royalty payments based on agreed upon royalty rates. Such rates can be fixed or variable depending on the terms of the agreement. The amount of revenue we recognize is determined based on a time period or on the agreed-upon royalty rate, extended by the number of units shipped by the customer. To determine the number of units shipped, we rely upon actual royalty reports from our customers when available and rely upon estimates in lieu of actual royalty reports when we have a sufficient history of receiving royalties from a specific customer for us to make an estimate based on available information from the licensee such as quantities held, manufactured and other information. These estimates for royalties necessarily involve the application of management judgment. As a result of our use of estimates, period-to-period numbers are “trued-up” in the following period to reflect actual units shipped. Such true-ups have not been significant. In cases where royalty reports and other information are not available to allow us to estimate royalty revenue, we recognize revenue only when royalty reports are received.

For contracts related to licenses of our technology that involve significant modification, customization or engineering services, we recognize revenue in accordance with the provisions of FASB ASC No. 605-35-25, Construction-Type and Production-Type Contracts Revenue Recognition. Revenues derived from such license contracts are accounted for using the percentage-of-completion method.

We determine progress to completion based on input measures using labor-hours incurred by our engineers. The amount of revenue recognized is based on the total contract fees and the percentage of completion achieved. Estimates of total project requirements are based on prior experience of customization, delivery and acceptance of the same or similar technology and are reviewed and updated regularly by management. If there is significant uncertainty about customer acceptance, or the time to complete the development or the deliverables by either party, we apply the completed contract method. If application of the percentage-of-completion method results in recognizable revenue prior to an invoicing event under a customer contract, we recognize the revenue and record an unbilled receivable assuming collectability is reasonably assured. Amounts invoiced to our customers in excess of recognizable revenues are recorded as deferred revenue.

Stock-based Compensation

We account for stock-based compensation in accordance with the provisions of FASB ASC No. 718-10-30, Stock Compensation Initial Measurement, which requires the measurement and recognition of compensation expense for all stock-based awards made to employees, directors including employee stock options, restricted stock units (“RSUs”), performance share awards and employee stock purchases under our Employee Stock Purchase Plan (“ESPP”) based on estimated fair values. Following the provisions of FASB ASC No. 718-50-25, Employee Share Purchase Plans Recognition, our ESPP is considered a compensatory plan, therefore, we are required to recognize compensation cost for grants made under the ESPP. We estimate the fair value of stock options granted using the Black-Scholes-Merton (“BSM”) option-pricing model and a single option award approach. The BSM model requires various highly subjective assumptions including volatility, expected option life, and risk-free interest rate. Management estimates volatility for a given option grant by evaluating the historical volatility of the period immediately preceding the option grant date that is at least equal in length to the option’s expected term. Consideration is also given to unusual events (either historical or projected) or other factors that might suggest that historical volatility will not be a good indicator of future volatility. The expected life of an award is based on historical experience and on the terms and conditions of the stock awards granted to employees, as well as the potential effect from options that had not been exercised at the time. In accordance with FASB ASC No. 718-10-35, Subsequent Measurement of Stock Compensation, we generally recognize stock-based compensation expense, net of estimated forfeitures, on a ratable basis for all share-based payment awards over the requisite service periods of the awards, which is generally the vesting period or the remaining service (vesting) period.

The assumptions used in calculating the fair value of share-based payment awards represent management’s best estimates. These estimates involve inherent uncertainties and the application of management’s judgment. If factors change and we use different assumptions, our stock-based compensation expense could be materially different in the future. In addition, we are required to estimate the expected forfeiture rate and recognize expense only for those shares expected-to-vest. If our actual forfeiture rate is materially different from our estimate, our recorded stock-based compensation expense could be different.

Financial Instruments

Cash Equivalents and Marketable Securities

All highly liquid investments with maturities of three months or less at the date of purchase are classified as cash equivalents. Our investments in debt and marketable equity securities have been classified and accounted for as available-for-sale. We determine the appropriate classification of such securities at the time of purchase and we reevaluate such classification as of each balance sheet date. We classify our marketable debt securities as short-term investments because of our intention to sell the securities within a relatively short period of time. Unrealized gains and losses on these investments are reported as a separate component of accumulated other comprehensive income (loss). The investments are adjusted for amortization of premiums and discounts to maturity and such amortization is included in interest income. We periodically assess whether our investments with unrealized loss positions are other than temporarily impaired. Other-than-temporary impairment charges exists when we have the intent to sell the security and we will more likely than not be required to sell the security before anticipated recovery or we do not expect to recover the entire amortized cost basis of the security. We determine other than temporary impairments based on the specific identification method and are reported in the consolidated statements of operations.

Derivative Financial Instruments

We account for our derivative instruments as either assets or liabilities and we carry them at fair value. Derivatives that are not defined as hedges must be adjusted to fair value through earnings. For derivative instruments that hedge the exposure to variability in expected future cash flows that are designated as cash flow hedges, the effective portion of the gain or loss on the derivative instrument is reported as a component of accumulated other comprehensive income in stockholders’ equity and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. The ineffective portion of the derivative gain (loss) is reported in each reporting period in other income (expense) on our consolidated statement of operations. To receive hedge accounting treatment, cash flow hedges must be highly effective in offsetting changes to expected future cash flows on hedged transactions.

Fair Value Measurements

We apply fair value accounting for all financial assets and liabilities and non-financial assets and liabilities that are recognized or disclosed at fair value in the financial statements on a recurring basis. We define fair value as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities, which are required to be recorded at fair value, we consider the principal or most advantageous market in which we would transact and the market-based risk measurements or assumptions that market participants would use in pricing the asset or liability, such as inherent risk, transfer restrictions and credit risk.

The fair value measurement standard establishes a consistent framework for measuring fair value whereby inputs used in valuation techniques are assigned a hierarchical level. The assignment to a level is based on whether the market participant assumptions used in determining fair value are obtained from independent sources (observable inputs) or reflect our own assumptions of market participant valuation (unobservable inputs). Categorization within the fair value hierarchy is determined by the lowest level of input that is significant to the fair value measurement. The following are the hierarchical levels of inputs to measure fair value:

Level 1	Quoted prices in active markets that are unadjusted and accessible at the measurement date for identical, unrestricted assets or liabilities;
Level 2	Quoted prices for identical assets and liabilities in markets that are inactive; quoted prices for similar assets and liabilities in active markets; or significant inputs that are observable, either directly or indirectly; or
Level 3	Prices or valuations that require inputs that are both unobservable and significant to the fair value measurement.

We consider an active market to be one in which transactions for the asset or liability occur with sufficient frequency and volume to provide pricing information on an ongoing basis, and view an inactive market as one in which there are few transactions for the asset or liability, the prices are not current, or price quotations vary substantially either over time or among market makers.

A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement.

Allowance for Doubtful Accounts

We review collectability of accounts receivable on an on-going basis and provide an allowance for amounts we estimate may not be collectible. During our review, we consider our historical experience, the age of the receivable balance, the credit-worthiness of the customer and the reason for the delinquency. Delinquent account balances are written-off after we have determined that the likelihood of collection is remote.

Table of Contents

Inventories

We record inventories at the lower of actual cost, determined on a first-in first-out (FIFO) basis, or market. Actual cost approximates standard cost, adjusted for variances between standard and actual. Standard costs are determined based on our estimate of material costs, manufacturing yields, costs to assemble, test and package our products and allocable indirect costs. We record differences between standard costs and actual costs as variances. These variances are analyzed and are either included on the consolidated balance sheet or the consolidated statement of operations in order to state the inventories at actual costs on a FIFO basis. Standard costs are re-evaluated quarterly.

Provisions are recorded for excess and obsolete inventory and are estimated based on a comparison of the quantity and cost of inventory on hand to our forecast of customer demand. Customer demand is dependent on many factors and requires us to use significant judgment in our forecasting process. We also make assumptions regarding the rate at which new products will be accepted in the marketplace and at which customers will transition from older products to newer products. Generally, inventories in excess of six months forecasted demand are written down to zero (unless specific facts and circumstances warrant no write-down or a write-down to a different value) and the related provision is recorded as a cost of revenue. Once a provision is established, it is maintained until the product to which it relates is sold or otherwise disposed of, even if in subsequent periods we forecast demand for the product.

Long-Lived Assets Including Goodwill and Other Acquired Intangible Assets

We review property and equipment, goodwill and other certain identifiable intangibles for impairment. Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. Recoverability of these assets is measured by comparison of their carrying amounts to future undiscounted cash flows the assets are expected to generate. If property and equipment and certain identifiable intangibles are considered to be impaired, the impairment to be recognized equals the amount by which the carrying value of the assets exceeds its fair market value. We do not amortize goodwill, rather such asset is required to be tested for impairment at least annually or sooner whenever events or changes in circumstances indicate that the assets may be impaired.

In 2009, we determined that our goodwill was impaired and recognized a total impairment charge of $19.2 million in our 2009 consolidated statement of operations under operating expenses, “Impairment of Goodwill,” which reduced goodwill to zero as of December 31, 2009. Also, in 2009, we made an impairment evaluation of our long-lived assets and determined that our investment in certain technology of Sunplus Technology Co., Ltd. (the “Sunplus IP”) was impaired and recognized an impairment charge of $28.3 million in our 2009 consolidated statement of operations under operating expenses, “Impairment of Intangible Assets,” which reduced the investment in Sunplus IP to zero as of December 31, 2009. There were no goodwill and other intangible asset impairment charges recorded in fiscal years 2010 and 2008.

We amortize our intangible assets with definite lives over their estimated useful lives and we review these assets for impairment. All of our acquired intangible assets were fully amortized as of December 31, 2010.

Income Taxes

We account for income taxes in accordance with the FASB ASC No. 740 (“ASC 740”), Accounting for Income Taxes. We make certain estimates and judgments in determining income tax expense for financial statement purposes. These estimates and judgments occur in the calculation of tax credits, tax benefits and deductions and in the calculation of certain tax assets and liabilities, which arise from differences in the timing of recognition of revenue and expense for tax and financial statement purposes. Significant changes to these estimates may result in an increase or decrease to our tax provision in the subsequent period when such a change in estimate occurs.

We use an asset and liability approach for accounting of deferred income taxes, which requires recognition of deferred income tax assets and liabilities for the expected future tax consequences of events that have been recognized in our financial statements, but have not been reflected in our taxable income. Estimates and judgments occur in the calculation of certain tax liabilities and in the determination of the recoverability of certain deferred income tax assets, which arise from temporary differences and carry-forwards. Deferred income tax assets and liabilities are measured using the currently enacted tax rates that apply to taxable income in effect for the years in which those tax assets are expected to be realized or settled. We regularly assess the likelihood that our deferred income tax assets will be realized based on the realization criteria set forth in ASC No. 740. To the extent that we believe any amounts are not more likely than not to be realized, we record a valuation allowance to reduce our deferred income tax assets. In the event we determine that all or part of the net deferred tax assets are not realizable in the future, an adjustment to the valuation allowance would be charged to earnings in the period such determination is made. Similarly, if we subsequently realize deferred income tax assets that were previously determined to be unrealizable, the respective valuation allowance would be reversed, resulting in an adjustment to earnings in the period such determination is made. In addition, the calculation of our tax liabilities involves dealing with uncertainties in the application of complex tax regulations. We recognize and measure potential liabilities based upon criteria set forth in ASC 740. Based upon these criteria, we estimate whether, and the extent to which, additional taxes will be due. If payment of these amounts ultimately proves to be unnecessary, the reversal of the liabilities may result in tax benefits being recognized in the period when we determine the liabilities are no longer necessary. If our estimate of tax liabilities is less than the amount ultimately assessed, a further charge to expense would result.

Significant judgment is required in determining any valuation allowance recorded against deferred income tax assets. In assessing the need for a valuation allowance, we consider all available evidence, including past operating results, estimates of future taxable income, and the feasibility of tax planning strategies. In the event that we change our determination as to the amount of deferred income tax assets that could be realized, we will adjust our valuation allowance with a corresponding effect to the provision for income taxes in the period in which such determination is made.

Significant judgment is also required in evaluating our uncertain tax positions under ASC 740 and determining our provision for income taxes. Although we believe our reserves for uncertain tax positions are reasonable, no assurance can be given that the final tax outcome of these matters will not be different from that which is reflected in our historical income tax provisions and accruals. We adjust these reserves in light of changing facts and circumstances, such as the closing of a tax audit or the refinement of an estimate. To the extent that the final tax outcome of these matters is different from the amounts recorded, such differences will affect the provision for income taxes in the period in which such determination is made. The provision for income taxes includes the effect of reserves for uncertain tax positions and any changes to the reserves that are considered appropriate, as well as the related net interest and penalties, if applicable.

Restructuring Expenses

We record provisions for workforce reduction costs and exit costs when they are probable and estimable. Severance paid under ongoing benefit arrangements is recorded in accordance with FASB ASC No. 712-10-25, Nonretirement Postemployment Benefits Recognition. One-time termination benefits and contract settlement and lease costs are recorded in accordance with FASB ASC No. 420-10-25, Exit or Disposal Cost Obligations Recognition. At each reporting date, we evaluate our accruals related to workforce reduction charges, contract settlement and lease costs to ensure that these accruals are still appropriate. Restructuring expense accruals related to future lease commitments on exited facilities include estimates, primarily related to sublease income over the lease terms and other costs for vacated properties. Increases or decreases to the accruals for changes in estimates are classified as restructuring expenses in the consolidated statement of operations.

Loss Contingencies

We are subject to the possibility of various loss contingencies arising in the ordinary course of business. We consider the likelihood of loss or impairment of an asset, or the incurrence of a liability, as well as our ability to reasonably estimate the amount of loss, in determining loss contingencies. An estimated loss contingency is accrued when it is probable that an asset has been impaired or a liability has been incurred and the amount of loss can be reasonably estimated. We record a charge equal to the minimum estimated liability for litigation costs or a loss contingency only when both of the following conditions are met: (i) information available prior to issuance of our consolidated financial statements indicates that it is probable that an asset had been impaired or a liability had been incurred at the date of the financial statements and (ii) the range of loss can be reasonably estimated. We regularly evaluate current information available to us to determine whether such accruals should be adjusted and whether new accruals are required.

From time to time, we are involved in disputes, litigation, and other legal actions. We are aggressively defending our current litigation matters. However, there are many uncertainties associated with any litigation, and these actions or other third-party claims against us may cause us to incur costly litigation and/or substantial settlement charges. In addition, the resolution of any future intellectual property litigation may require us to make royalty payments, which could adversely affect gross margins in future periods. If any of those events were to occur, our business, financial condition, results of operations, and cash flows could be adversely affected. The actual liability in any such matters may be materially different from our estimates, which could result in the need to adjust our liability and record additional expenses.

Guarantees, Indemnifications and Warranty Liabilities

Certain of our licensing agreements indemnify our customers for expenses or liabilities resulting from claimed infringements of patent, trademark or copyright by third parties related to the intellectual property content of our products. Certain of these indemnification provisions are perpetual from execution of the agreement and, in some instances; the maximum amount of potential future indemnification is not limited. To date, we have not paid any such claims or been required to defend any lawsuits with respect to a claim.

At the time of revenue recognition, we provide an accrual for estimated costs (included in accrued liabilities in the accompanying consolidated balance sheets) to be incurred pursuant to our warranty obligation. Our estimate is based primarily on historical experience.

Commitments, Contingencies and Concentrations

Historically, a relatively small number of customers and distributors have generated a significant portion of our revenue. For instance, our top five customers, including distributors, generated 58.3%, 44.2% and 55.1% of our revenue in 2010, 2009 and 2008, respectively. The percentage of revenue generated through distributors tends to be significant, since many OEMs rely upon third-party manufacturers or distributors to provide purchasing and inventory management functions. In 2010, 61.1% of our revenue was generated through distributors, compared to 59.2% and 52.1% in 2009 and 2008, respectively. Samsung Electronics accounted for 17.0% of our revenue in 2010. Microtek Corporation comprised 11.0%, 11.9% and 11.8% of our revenue in 2010, 2009 and 2008, respectively. Weikeng Industrial generated 9.9%, 10.3% and 11.5% of our revenue in 2010, 2009 and 2008, respectively. Innotech Corporation comprised 11.3% and 10.5% of our revenue in 2010 and 2008, respectively. Revenue from World Peace Inc. comprised 14.6% of our revenue in 2008.

We have been named as defendants in a number of judicial and administrative proceedings incidental to its business and may be named again from time to time, and although adverse decisions or settlements may occur in one or more of such cases, the final resolution of these matters, individually or in the aggregate, is not expected to have a material adverse effect on our results of operations, financial position or cash flows.

A significant portion of our revenue is generated from products sold overseas. Sales (including licensing) to customers in Asia, including distributors, generated 73.6%, 67.3% and 71.2% of our revenue in 2010, 2009 and 2008, respectively. The reason for our geographical concentration in Asia is that most of our products are incorporated into flat panel displays, graphic cards and motherboards, the majority of which are manufactured in Asia. The percentage of our revenue derived from any country is dependent upon where our end customers choose to manufacture their products. Accordingly, variability in our geographic revenue is not necessarily indicative of any geographic trends, but rather is the combined effect of new design wins and changes in customer manufacturing locations. Primarily all revenue to date has been denominated in U.S. dollars.

Recent Accounting Pronouncements

In December 2010, FASB issued Accounting Standards Update (ASU) No. 2010-29, Business Combinations (ASC Topic 805). The amendments in this update specify that if a public entity presents comparative financial statements, the entity should disclose revenue and earnings of the combined entity as though the business combination(s) that occurred during the current year had occurred as of the beginning of the comparable prior annual reporting period only. The amendments also improve the usefulness of the pro forma revenue and earnings disclosures by requiring a description of the nature and amount of material, nonrecurring pro forma adjustments that are directly attributable to the business combination(s). The amendments in this update are effective for fiscal years, and interim periods within those years, beginning after December 15, 2010. Early adoption is permitted. As we did not enter into any business combinations in fiscal year 2010, we believe that the adoption this update will not have any material impact on our financial statement disclosures. However, if we enter into material business combinations in the future, the adoption of this update may have significant impact on our financial statement disclosures.

In December 2010, FASB issued ASU No. 2010-28, Intangibles - Goodwill and Other (ASC Topic 350). Under Topic 350 on goodwill and other intangible assets, testing for goodwill impairment is a two-step test. When a goodwill impairment test is performed (either on an annual or interim basis), an entity must assess whether the carrying amount of a reporting unit exceeds its fair value (Step 1). If it does, an entity must perform an additional test to determine whether goodwill has been impaired and to calculate the amount of that impairment (Step 2). The amendments in this update modify Step 1 of the goodwill impairment test for reporting units with zero or negative carrying amounts. For those reporting units, an entity is required to perform Step 2 of the goodwill impairment test if it is more likely than not that a goodwill impairment exists. In determining whether it is more likely than not that a goodwill impairment exists, an entity should consider whether there are any adverse qualitative factors indicating that an impairment may exist. The qualitative factors require that goodwill of a reporting unit be tested for impairment between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. The amendments in this update are effective for fiscal years, and interim periods within those years, beginning after December 15, 2010. Early adoption is not permitted. As we do not have any significant intangible assets, we believe that the impact of adopting this update will not be material on our consolidated results of operations and financial position.

In April 2010, FASB issued ASU No. 2010-17, Revenue Recognition-Milestone Method (ASC Topic 605). The amendments in this update provide guidance on the criteria that should be met for determining whether the milestone method of revenue recognition is appropriate. A vendor can recognize consideration that is contingent upon achievement of a milestone in its entirety as revenue in the period in which the milestone is achieved only if the milestone meets all criteria to be considered substantive. Determining whether a milestone is substantive requires judgment that should be made at the inception of the arrangement. To meet the definition of a substantive milestone, the consideration earned by achieving the milestone (1) would have to be commensurate with either the level of effort required to achieve the milestone or the enhancement in the value of the item delivered, (2) would have to relate solely to past performance, and (3) should be reasonable relative to all deliverables and payment terms in the arrangement. No bifurcation of an individual milestone is allowed and there can be more than one milestone in an arrangement. The amendments in this update are effective on a prospective basis for milestones achieved in fiscal years, and interim periods within those years, beginning on or after June 15, 2010. Early adoption is permitted. We do not believe the impact of the adoption of this guidance will have a material effect on our consolidated results of operations and financial position.

In January 2010, FASB issued ASU No. 2010-06, Fair Value Measurements and Disclosures (ASC Topic 820) — Improving Disclosures About Fair Value Measurements. The ASU requires new disclosures about transfers into and out of Levels 1 and 2 and separate disclosures about purchases, sales, issuances, and settlements relating to Level 3 measurements. It also clarifies existing fair value disclosures about the level of disaggregation and about inputs and valuation techniques used to measure fair value. The new disclosures and clarifications of existing disclosures are effective for interim and annual reporting periods beginning after December 15, 2009, except for the disclosures about purchases, sales, issuances, and settlements in the roll forward of activity in Level 3 fair value measurements. Those disclosures are effective for fiscal years beginning after December 15, 2010, and for interim periods within those fiscal years. Other than requiring additional disclosures, the adoption of this new guidance did not have a material impact on our consolidated results of operations and financial position.

In October 2009, the Financial Accounting Standards Board (FASB) issued ASU No. 2009-14, Software (Accounting Standards Codification (ASC) Topic 985) - Certain Revenue Arrangements That Include Software Elements, a consensus of the FASB Emerging Issues Task Force. This guidance modifies the scope of ASC subtopic 965-605, Software-Revenue Recognition to exclude from its requirements (a) non-software components of tangible products and (b) software components of tangible products that are sold, licensed, or leased with tangible products when the software components and non-software components of the tangible product function together to deliver the tangible product’s essential functionality. This update requires expanded qualitative and quantitative disclosures and is effective for our first quarter of fiscal year 2011. We are currently evaluating the impact of adopting this update on our consolidated results of operations and financial position.

In October 2009, the FASB issued ASU No. 2009-13, Revenue Recognition (ASC Topic 605) - Multiple-Deliverable Revenue Arrangements, a consensus of the FASB Emerging Issues Task Force. This guidance modifies the fair value requirements of ASC subtopic 605-25, Revenue Recognition-Multiple Element Arrangements by allowing the use of the “best estimate of selling price” in addition to vendor-specific objective evidence (VSOE) and verifiable objective evidence (VOE) (now referred to as TPE standing for third-party evidence) for determining the selling price of a deliverable. A vendor is now required to use its best estimate of the selling price when VSOE or TPE of the selling price cannot be determined. In addition, the residual method of allocating arrangement consideration is no longer permitted. This update requires expanded qualitative and quantitative disclosures and is effective for our first quarter of fiscal year 2011. We are currently evaluating the impact of adopting this update on our consolidated results of operations and financial position.

Total revenue	$	191,347			27.1	%	$	150,589			-45.1	%	$	274,415

Our consolidated total revenue for the year ended December 31, 2010 was $191.3 million, an increase of $40.8 million, or 27.1%, from the year ended December 31, 2009. The significant increase in revenue was primarily due to increased demand for our CE products and the increase in our licensing revenue. Revenue from our CE products and licensing during the year ended December 31, 2010 increased by $29.0 million or 28.3% and $10.6 million or 37.9%, respectively, compared to the same period in 2009. The $1.5 million or 13.6% increase in revenue in 2010 compared to 2009 from our storage product line also contributed positively to the total revenue in 2010. The increase in our CE and storage products was primarily due to an increase in unit product shipments. Our unit shipments during the year ended December 31, 2010 for CE and storage increased by 38.5% and 11.8%, respectively, compared to the same period in 2009. The higher unit shipments in our CE product line were primarily driven by increased demand for our port processors from the DTV market and higher demand for our mobile products due to the new products we introduced in 2010. The increase in unit shipments in our storage product was primarily due to higher demand for our SATA controllers. The impact of the 38.5% increase in unit shipments to our CE revenue was partially offset by a 7.7% decrease in the average selling price of our CE products.

Our licensing activity is complementary to our product sales and helps us to monetize our intellectual property and accelerate market adoption curves associated with our technology. IP licensing continues to represent an important part of our overall business. Revenue from licensing accounted for 20.1% and 18.5% of our total revenue for the years ended December 31, 2010 and 2009, respectively. Licensing revenue during the year ended December 31, 2010 increased by $10.6 million or 37.9% when compared to the same period in 2009. The significantly higher licensing revenue during the year ended December 31, 2010 compared to the licensing revenue during the same period in 2009 was primarily due to the increase in licensing activities in 2010 and to the $7.1 million additional royalties we recorded during fiscal year 2010 as a result of the completion of certain licensing audit activities during that year.

Total revenue for 2009 was $150.6 million and represented a decline of 45.1% from 2008 levels. Revenue from all our product lines in 2009 decreased when compared to revenue generated in 2008. Revenue in 2009 from CE, PC, storage and licensing decreased by 38.9%, 77.8%, 55.3% and 32.3%, respectively, when compared to the revenue generated in these product lines in 2008. Revenue from our product lines decreased by $110.5 million or 47.4% from $233.2 million in 2008 to $122.7 million in 2009. Product shipments in 2009 decreased by approximately 31.1% and average selling price declined by approximately 24.8% when compared to the shipments and average selling price in 2008, primarily due to the ongoing global recession, increased competition, product mix changes in the DTV market and our ongoing product transition as customers transition from HDMI receivers to more cost effective Port Processors. Another factor that caused the unit shipments to decrease from fiscal year 2008 to 2009 was the integration of the HDMI and SATA functionality into PC chip sets.

We also experienced significant declines in our licensing revenues for the year ended December 31, 2009 as compared to the licensing revenues generated in 2008. Revenue from licensing accounted for 18.5% and 15.0% of our total revenues for the years ended December 31, 2009 and 2008, respectively. The decrease in licensing revenues in 2009 as compared to 2008 was due primarily to the overall softening of demand for consumer products as a result of the deterioration of the global economic climate.

Total gross profit margin		59.4	%					53.7	%					58.6	%

Cost of revenue consists primarily of costs incurred to manufacture, assemble and test our products, and costs to license our technology which involves modification, customization or engineering services, as well as other overhead costs relating to the aforementioned costs including stock-based compensation expense. Our overall gross profit, as a percentage of revenue, was 59.4% for the year ended December 31, 2010 and 53.7% for the year ended December 31, 2009. Total cost of revenue for the year ended December 31, 2010 increased by $8.0 million or 11.4%, when compared to the total cost of revenue in the same period in 2009. The increase in the total cost of revenue was primarily due to the growth in revenue volume during the same comparative periods.

Product gross profit margin for the year ended December 31, 2010 was 49.3%, compared to 44.1% for the year ended December 31, 2009. The 5.2% increase in product gross profit margin during the year ended December 31, 2010 compared to the same period in 2009 was primarily attributable to the 5.3% increase in the gross profit margin due to the wafer, testing and assembly cost reductions in 2010 and 4.0% increase in the gross profit margin due to better yields, better overhead absorption resulting from our higher revenue volume in 2010 than in 2009 and lower stock-based compensation expense, partially offset by the 4.1% decrease in the gross profit margin due to the decrease in the average selling price.

Our licensing gross profit margin for the year ended December 31, 2010 was 99.3%, compared to 95.7% for the year ended December 31, 2009. Licensing gross margin during the year ended December 31, 2010 increased by 3.6%, compared to the same period in 2009 primarily due to higher revenue and lower mix of IP customization projects during the year ended December 31, 2010 compared to the same period in 2009.

Overall gross profit margin was 53.7% and 58.6% for the years ended December 31, 2009 and 2008, respectively. Product mix, unfavorable variances and the impact of fixed overhead with lower revenue volume during the year ended December 31, 2009 were the primary reasons for the decrease in cost of revenue and the decrease in gross margin as percentage of revenue in 2009 compared to 2008. Increased competition in all business lines as reflected in the decline in the average selling price also contributed to the overall decrease in the gross margin in 2009 when compared to 2008.

Research and development (R&D). R&D expense consists primarily of employee compensation and benefits, fees for independent contractors, the cost of software tools used for designing and testing our products and costs associated with prototype materials. R&D expense for the year ended December 31, 2010 decreased by $12.9 million or 18.9%, when compared to the R&D expense incurred in the same period in 2009. The decrease in R&D expense was primarily attributable to the decrease in stock-based compensation expense and reduced expenses due to the restructuring programs implemented in 2009 and expense management controls implemented internally. R&D expense for the year ended December 31, 2010 included stock-based compensation expense of $2.6 million, as compared to $6.3 million for the year ended December 31, 2009. The stock-based compensation expense for the year ended December 31, 2010 was significantly lower than the expense in the same period in 2009 primarily due to the $1.1 million cumulative adjustment we recognized in 2009 related to the errors we identified as to how our third party software provider was calculating the stock-based compensation expense. The lower average headcount in 2010 compared to 2009 due to the restructuring programs implemented in 2009 also significantly contributed to the lower stock-based compensation expense in 2010 compared to 2009. At the end of 2009, we closed the two R&D sites in Germany resulting in a reduction of R&D expense. These reductions were partially offset by additional expenses incurred as a result of increasing our R&D presence in Asia in 2010. The increase in bonus compensation of $1.6 million in 2010 compared to 2009 driven by the better overall company performance also partially offset the decrease in R&D expense in 2010 compared to 2009.

R&D expenses decreased by $16.6 million or 19.6% in the year ended December 31, 2009 as compared to the comparable period in 2008, primarily due to lower compensation related expenses as a result of lower headcount due to restructuring activities and lower R&D project related and tape-out expenses, partially offset by the $1.1 million additional stock-based compensation expense due to the previously mentioned cumulative adjustment in 2009.

(1) Includes stock-based compensation expense		4,152						10,863						10,893

Selling, general and administrative (SG&A). SG&A expense consists primarily of compensation, including stock-based compensation expense, sales commissions, professional fees, and marketing and promotional expenses. SG&A expense during the year ended December 31, 2010 was $8.3 million or 15.1% lower than the SG&A expense incurred in the same period in 2009 primarily due to the nonrecurring charges that we incurred in 2009. In 2009, we incurred approximately $2.0 million in professional fees associated with a potential strategic acquisition which we evaluated but decided not to pursue, $1.2 million compensation expense related to the compensation package provided to our former Chief Executive Officer upon his resignation in September 2009 and $2.8 million stock-based compensation expense cumulative adjustment pertaining to the errors we identified with respect to the stock-based compensation expense calculated by our third-party software. Not considering the impact of these 2009 nonrecurring charges, SG&A expense for the year ended December 31, 2010 would have been $2.3 million lower than what was incurred in the same period in 2009, which was primarily attributable to the lower compensation related expenses resulting from the restructuring programs implemented in 2009. The increase in bonus of $1.9 million in 2010 compared to 2009 driven by the better overall company performance partially offset the decrease in SG&A expense in 2010 compared to 2009.

SG&A expense for the year ended December 31, 2009 was $16.7 million or 23.3% lower than in the year ended December 31, 2008 due to lower compensation related expenses and legal expenses, partially offset by the non-recurring expenses that we incurred in 2009, such as the $2.8 million stock-based compensation cumulative adjustment, $2.0 million professional fees and $1.2 million compensation given to the CEO. Had it not been for these one-time expenses, SG&A expense for the year ended December 31, 2009 would have been lower by $22.7 million or 31.7% when compared to the SG&A expense for the same period in 2008. The decrease in SG&A expense was mainly attributable to the significant decrease in average head count because of the restructuring programs completed in 2009.

Restructuring. The total restructuring expense for the year ended December 31, 2010 consisted primarily of $2.0 million related to contract termination cost, a charge of $0.9 million relating to operating lease termination costs and a charge of $0.3 million related to retirement of certain fixed assets. During 2010, the Company was in the process of transitioning certain R&D work from Europe to Asia and as a result of this transition, the Company decided to cease using the services of certain European engineers which resulted in an accrual of future costs of $2.0 million payable under the related contract without any future economic benefit to the Company. The Company recorded such future costs as restructuring expense in 2010.

In 2009, we announced restructuring plans to realign and focus our resources on our core competencies and in order to better align our revenues and expenses. The restructuring expense for the year ended December 31, 2009, consisted primarily of $22.1 million of employee severance and benefit arrangements related to the closure in 2009 of our two R&D sites in Germany, a charge of $0.6 million relating to retirement of certain assets and a charge of $0.2 million relating to operating lease termination costs.

In 2008, we announced restructuring plans to improve the effectiveness and efficiency of our operating model as part of our program to pursue continuous improvement. The restructuring expense for the year ended December 31, 2008, consisted primarily of $4.6 million related to employee severance and benefit arrangements due to the termination of 57 employees, a charge of $1.1 million relating to retirement of certain assets and a charge of $0.2 million relating to operating lease termination costs.

Amortization of intangible assets. Amortization of intangible assets was $0.1 million for the year ended December 31, 2010, as compared to $4.5 million in 2009 and $6.3 million in 2008. The significant sequential decrease in the amortization of intangible assets was primarily due to the complete amortization of acquired intangible assets and write-off in 2009 of the investment in an intellectual property. Please see related discussion in Impairment of Intangible Assets below.

Impairment of intangible assets. In 2009, we determined that, in light of certain changes to our product strategy, the intellectual property licensed from Sunplus Technology Co., Ltd in February 2007 (the “Sunplus IP”) no longer aligned with our product roadmap and therefore would not be used. In connection with the decision to discontinue the use of the Sunplus IP, we wrote-off the unamortized balance of the investment in Sunplus IP of $28.3 million and recognized a pre-tax impairment charge of $28.3 million in the 2009 consolidated statement of operations under operating expense, “Impairment of Intangible Assets.” See more discussion about this impairment in Note 11 of our Notes to Consolidated Financial Statements under Item I of Part IV. There was no impairment of intangible assets in 2010 and 2008.

Impairment of Goodwill. In 2009, we assessed goodwill for impairment and noted indicators of impairment including a sustained and significant decline in our stock price, depressed market conditions and declining industry trends. In 2009, our stock price had been in a period of sustained decline and the business climate had deteriorated substantially in light of the economic crisis. Based on the result of the impairment analysis that we performed, we determined that the goodwill was impaired. As such, we wrote off the entire goodwill balance and recognized goodwill impairment charge of approximately $19.2 million in the 2009 consolidated statement of operations under operating expense, “Impairment of Goodwill.” See more discussion about this impairment in Note 12 of our Notes to Consolidated Financial Statements under Item I of Part IV. There was no impairment of goodwill in 2010 and 2008.

Interest income and other, net. Interest income and others, net in 2010, principally included interest income of $2.3 million and a favorable transfer to income of a subsidiary’s accumulated foreign currency translation adjustments of $1.4 million from accumulated Other Comprehensive Income (OCI) presented under consolidated statement of stockholders’ equity. In 2010, we transferred the accumulated foreign currency translation adjustment of our wholly owned subsidiary in Germany whose facilities and offices had been substantially liquidated during 2010, to income.

Interest income for the year ended December 31, 2010 decreased by 18.8% compared to the same period in 2009 primarily due to the decline in interest rates as a result of macro-economic conditions. Interest income for the year ended December 31, 2009 decreased by 38.3% compared to the same period in 2008 mainly due to the lower average total cash balances in 2009 compared to 2008.

Provision (benefit) for income taxes. For the year ended December 31, 2010, we recorded an income tax provision of $3.6 million, compared to income tax provision of $14.8 million in 2009 and income tax benefit of $11.9 million in 2008. Our effective income tax rate was 30.6% in 2010. In 2010, the difference between the expense for income taxes and the income tax expense determined by applying the statutory federal income tax rate of 35% was due primarily to foreign withholding taxes and changes in the valuation allowance.

For the year ended December 31, 2009, we recorded an income tax provision of $14.8 million, compared to income tax benefit of $11.9 million in 2008. Our effective income tax rate was (13%) in 2009. In 2009, the difference between the expense for income taxes and the income tax benefit determined by applying the statutory federal income tax rate of 35% was due primarily to the following items: (1) $43.0 million of tax expense related to a valuation allowance being recorded to offset deferred taxes recorded on the balance sheet, (2) $3.8 million of expense associated with the geographic and tax jurisdictional mix of earnings within the Company’s global business structure, (3) $7.6 million of tax expense associated with stock-based compensation expense being reversed for tax purposes, (4) $5.3 million expense of foreign unbenefited losses, and (5) $3.8 million tax expense associated with non-deductible goodwill write-off for book purposes. Offsetting these expenses are benefits of: (1) $5.6 million related to a worthless stock deduction for its investment in the Company’s German subsidiary, and (2) $3.2 million related to federal and state research and development tax credits generated during 2009.

For the year ended December 31, 2008, we recorded an income tax benefit of $11.9 million. Our effective income tax rate was 656% in 2008. In 2008, the difference between the benefit for income taxes and the income tax determined by applying the statutory federal income tax rate of 35% was due primarily to the following items: (1) $5.0 million of tax benefits related to the geographic and tax jurisdictional mix of earnings within the Company’s global business structure, (2) $4.2 million of tax benefits associated with research and development tax credits and related FIN 48 reserves re-evaluated by the Company during the fourth quarter of 2008 upon completion of a study of credits claimed through 2007, (3) $1.6 million of tax benefits related to federal and state research and development tax credits generated during 2008, and (4) $0.9 million of tax benefits associated with tax exempt interest income.

At December 31, 2010, we had $184.7 million of working capital including $190.5 million of cash, cash equivalents and short-term investments. Cash and cash equivalents and short-term investments increased by $39.9 million from $150.6 million in 2009 to $190.5 million in 2010 primarily due to net income tax refunds totaling to approximately $18.1 million, proceeds from stock option exercises and purchases under our employee stock purchase program totaling to approximately $5.6 million, and increased cash collections of receivables, partially offset by the $17.4 million cash used to pay our restructuring liability.

The significant components of our working capital are cash and cash equivalents, short-term investments, accounts receivable, inventories, deferred income taxes and prepaid expenses and other current assets, reduced by accounts payable, accrued and other current liabilities, deferred license revenue and deferred margin on sales to distributors. Working capital at December 31, 2010 increased by approximately $21.3 million when compared to the working capital at December 31, 2009 primarily due to the $23.0 million increase in operating assets, partially offset by the $1.7 million increase in operating liabilities. The $23.0 million increase in operating assets was primarily related to the $39.9 million increase in total cash, cash equivalents and short-term investments and $2.5 million increase in inventories, partially offset by the $21.0 million decrease in prepaid expenses and other current assets. The $2.5 million increase in inventories was primarily due to the increasing demand for our products while the $21.0 million decrease in prepaid expenses and other current assets was primarily attributed to the net income tax refunds. The $1.7 million increase in operating liabilities was primarily due to the $10.5 million increase in deferred margin on sales to distributors and $1.1 million increase in deferred license revenue, partially offset by the $10.4 million decrease in accrued and other current liabilities. The $10.5 million increase in deferred margin on sales to distributors was mainly due to the increasing activities with our distributors driven by the increasing demand for our products while the $10.4 million decrease in accrued and other current liabilities was mainly attributable to the payment of the restructuring liability, primarily related to the severance and termination benefits.

We believe that our current cash, cash equivalents and short-term investment balances together with income derived from sales of our products and licensing will be sufficient to meet our liquidity requirements for at least the next twelve months.

At December 31, 2009, we had $163.5 million of working capital including $150.6 million of cash, cash equivalents and short-term investments. Cash and cash equivalents and short-term investments decreased by $34.4 million from $185.0 million in 2008 to $150.6 million in 2009 primarily due to the cash used in operating and investing activities for the year ended December 31, 2009.

The significant components of our working capital are cash and cash equivalents, short-term investments, accounts receivable, prepaid expenses and other current assets, inventories and deferred income taxes reduced by accounts payable, accrued and other current liabilities, deferred license revenue, and deferred margin on sales to distributors. Working capital at December 31, 2009 decreased by approximately $22.6 million when compared to the working capital at December 31, 2008 primarily due to the decreases in cash and cash equivalents and short-term investments, the increase in operating assets, such as accounts receivable and prepaid expenses and other current assets and the decrease in deferred margin on sales to distributors, partially offset by the decrease in inventories and the increase in operating liabilities, such as accounts payable and accrued and other liabilities.

Operating Activities

The $46.5 million cash generated from our operating activities during the year ended December 31, 2010 was primarily due to net income, a decrease in prepaid expenses and other assets and an increase in operating liabilities, such as deferred license revenue and deferred margin on sales to distributors, partially offset by the increases in net accounts receivable and inventories and by the decrease in accrued and other liabilities.

Prepaid expenses and other assets decreased by approximately $21.4 million primarily due to net income tax refunds during the year ended December 31, 2010. Deferred margin on sales to distributors increased by $10.5 million, which was attributable to the increasing activities with our distributors driven by the increasing demand for our products. Deferred license revenue increased by $2.6 million primarily due to the new licensing agreements we entered into during the year ended December 31, 2010. Accrued and other liabilities decreased by $8.1 million primarily due to the $15.5 million net decrease in the balance of restructuring liability due to payments of severance benefits during the year ended December 31, 2010, partially offset by the increases in other accrued liabilities, such as accrued payroll and related expenses, which increased by $3.9 million, and royalties payable, which increased by $3.0 million. The increase in accrued payroll and related expenses was attributable mainly to the bonus and sales commission accruals, which was a direct result of the significant increase in revenues during fiscal year 2010 compared to fiscal year 2009. The increase in royalties payable was mainly due to the increase in the share of the HDMI founders as a result of increased royalties in 2010 compared to 2009.

The $29.7 million cash used in operating activities during the year ended December 31, 2009 was primarily due to the cash used for working capital as a result of the increase in operating assets, such as accounts receivable and prepaid expenses and other current assets and decrease in deferred margin on sales to distributors, partially offset by the decrease in inventories and the increase in operating liabilities, such as accounts payable and accrued liabilities and other current liabilities.

Net accounts receivable increased to $21.7 million at December 31, 2009 as compared to $5.9 million at December 31, 2008 primarily due to the timing of invoicing, distributor price protection credits and collection. Prepaid expenses and other current assets increased by $11.8 million primarily due to income tax receivable and prepayment for certain R&D engineering services. Deferred margin on sales to distributors decreased by $3.9 million because of lower activities with our distributors. Inventory decreased by $5.0 million primarily due to our tighter inventory management and lower inventory requirements for the first quarter of fiscal year 2010. Accounts payable increased by $3.6 million mainly because of the timing of vendor payments. Accrued and other liabilities increased by $6.4 million primarily due to the $13.8 million increase in restructuring accrual, partially offset by the decreases in bonus accrual of approximately $1.6 million, accrued payroll and other payroll related expenses of approximately $2.6 million, accruals for software and IP liabilities of approximately $2.5 million and other miscellaneous accruals. The decrease in bonus accruals was due to the elimination of the bonus program in 2009 while the decrease in accrued payroll and other payroll related expenses was primarily due to (1) decrease in accrued commissions due to lower sales; and, (2) decrease in ESPP liability due to lower participation in 2009 compared to 2008.

In the year ended December 31, 2008, our operating activities provided $25.6 million of cash. The cash generated from working capital consisted primarily of the strong cash collection on our accounts receivable, efficient management of inventory offset by cash used in prepaid expenses and other assets, accounts payables, accrued liabilities, deferred revenue and deferred margin on sale to distributors.

Financing Activities

The $4.0 million net cash generated from our financing activities during the year ended December 31, 2010 was primarily due to the proceeds from stock option exercises and purchases under our employee stock purchase program totaling approximately $5.6 million and to the excess tax benefits from employee stock-based transactions of approximately $0.8 million, partially offset by payments to vendor of financed purchases of software and intangibles of approximately $1.2 million and cash used to repurchase restricted stock units for income tax withholding of approximately $1.2 million.

The $1.4 million net cash generated from our financing activities during the year ended December 31, 2009 was primarily due to the proceeds from stock option exercises and purchases under our employee stock purchase program of approximately $2.8 million, partially offset by payments to vendor of financed purchases of software and intangibles of approximately $1.2 million and cash used to repurchase restricted stock units for income tax withholding of approximately $0.3 million.

Contractual Obligations

In December 2002, we entered into a non-cancelable operating lease agreement for our principal operating facility in Sunnyvale, California. In June 2004, we entered into an amendment to the operating lease agreement to expand the leased premises. In May 2006, we entered into an amendment of the lease agreement to further expand the leased premises, to extend the lease expiration date to July 2011, and to set the monthly rental payments at $146,237, with annual increases of 3% thereafter. We also lease an operating facility in Irvine, California, pursuant to a non-cancelable operating lease agreement with a term that extends through November 2012 and provides for base monthly rental payments of approximately $14,800 is required.

We also lease office spaces in China, Japan, Korea, and Taiwan.

Rent expense totaled $2.6 million, $4.1 million and $5.1 million for the years ended December 31, 2010, 2009 and 2008, respectively.

Long-Term Liquidity

Based on our estimated cash flows, we believe our existing cash and short-term investments are sufficient to meet our capital and operating requirements for at least the next twelve months. We expect to continue to invest in property and equipment in the ordinary course of business. Our future operating and capital requirements depend on many factors, including the levels at which we generate product revenue and related margins, the extent to which we generate cash through stock option exercises and proceeds from sales of shares under our employee stock purchase plan, the timing and extent of licensing revenue, investments in inventory, property, plant and equipment and accounts receivable, the cost of securing access to adequate manufacturing capacity, our operating expenses, including legal and patent assertion costs and general economic conditions. In addition, cash may be required for future acquisitions should we choose to pursue any. While, we believe that our current cash, cash equivalents and short-term investment balances together with income derived from sales of our products and licensing will be sufficient to meet our liquidity requirements in the foreseeable future, to the extent existing resources and cash from operations are insufficient to support our activities, we may need to raise additional funds through public or private equity or debt financing. These funds may not be available when we need them, or if available, we may not be able to obtain them on terms favorable to us.

Global credit and financial markets have experienced extreme disruptions since mid-2008, including severely diminished liquidity and credit availability, declines in consumer confidence, declines in economic growth, increases in unemployment rates, and uncertainty about economic stability. There can be no assurance that there will not be further deterioration in credit and financial markets and confidence in economic conditions. These economic uncertainties affect businesses such as ours in a number of ways, making it difficult to accurately forecast and plan our future business activities. The current tightening of credit in financial markets may lead consumers and businesses to postpone spending, which may cause our customers to cancel, decrease or delay their existing and future orders with us. In addition, financial difficulties experienced by our suppliers or distributors could result in product delays, increased accounts receivable defaults and inventory challenges.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

Interest Rate Risk

The primary objective of our investment activities is to preserve principal while at the same time maximizing the income we receive from our investments without significantly increasing risk. To achieve this objective, we maintain our portfolio of cash equivalents and short-term investments in a variety of securities, including government and corporate securities and money market funds. These securities are classified as available for sale and consequently are recorded on the balance sheet at fair value with unrealized gains or losses reported as a separate component of accumulated other comprehensive income (loss). We also limit our exposure to interest rate and credit risk by establishing and monitoring clear policies and guidelines of our fixed income portfolios. The guidelines also establish credit quality standards, limits on exposure to any one issuer and limits on exposure to the type of instrument. Due to the limited duration and credit risk criteria established in our guidelines we do not expect the exposure to interest rate risk and credit risk to be material. If interest rates rise, the market value of our investments may decline, which could result in a realized loss if we are forced to sell an investment before its scheduled maturity. As of December 31, 2010, we had an investment portfolio of securities as reported in short-term investments, including those classified as cash equivalents of approximately $166.4 million. A sensitivity analysis was performed on our investment portfolio as of December 31, 2010. This sensitivity analysis was based on a modeling technique that measures the hypothetical market value changes that would result from a parallel shift in the yield curve of plus 50, 100, or 150 basis points over a twelve-month time horizon.

The following represents the potential change to the value of our investments given a shift in the yield curve used in our sensitivity analysis.

	0.5%				1.0%				1.5%
	$ 656,000				$ 1,313,000				$ 1,969,000

As of December 31, 2009, we had an investment portfolio of securities as reported in short-term investments, including those classified as cash equivalents of approximately $128.4 million. These securities are subject to interest rate fluctuations. The following represents the potential change to the value of our fixed income securities given a shift in the yield curve used in our sensitivity analysis.

	0.5%				1.0%				1.5%
	$ 427,000				$ 854,000				$ 1,281,000

Financial instruments that potentially subject us to significant concentrations of credit risk consist primarily of cash equivalents and short-term investments and accounts receivable. A majority of our cash and investments are maintained with a major financial institutions headquartered in the United States. As part of our cash and investment management processes, we perform periodic evaluations of the credit standing of the financial institutions and we have not sustained any credit losses from investments held at these financial institutions. The counterparties to the agreements relating to our investment securities consist of various major corporations and financial institutions of high credit standing.

We perform on-going credit evaluations of our customers’ financial condition and may require collateral, such as letters of credit, to secure accounts receivable if deemed necessary. We maintain an allowance for potentially uncollectible accounts receivable based on our assessment of collectability.

Foreign Currency Exchange Risk

A majority of our revenue, expense, and capital purchasing activities are transacted in U.S. dollars. However, certain operating expenditures and capital purchases are incurred in or exposed to other currencies, primarily the Euro, the South Korean Won, Taiwan Dollar and the Chinese Yuan. Additionally, many of our foreign distributors price our products in the local currency of the countries in which they sell. Therefore, significant strengthening or weakening of the U.S. dollar relative to those foreign currencies could result in reduced demand or lower U.S. dollar prices or vice versa, for our products, which would negatively affect our operating results. Cash balances held in foreign countries are subject to local banking laws and may bear higher or lower risk than cash deposited in the United States. The following represents the potential impact of a change in the value of the U.S. dollar compared to the foreign currencies which we use in our operations. The following represents the potential impact of a change in the value of the U.S. dollar compared to the Euro, British Pound, Japanese Yen, Chinese Yuan, Taiwan Dollar and Korean Won for the years ended December 31, 2010 and 2009. This sensitivity analysis aggregates our annual activity in these currencies, translated to U.S. dollars, and applies a change in the U.S. dollar value of 5%, 7.5% and 10%.

Item 9A. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Management is required to evaluate our disclosure controls and procedures, as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Disclosure controls and procedures are controls and other procedures designed to ensure that information required to be disclosed in our reports filed under the Exchange Act, such as this Annual Report on Form 10-K, is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms. Disclosure controls and procedures include controls and procedures designed to ensure that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer as appropriate to allow timely decisions regarding required disclosure. Our disclosure controls and procedures include components of our internal control over financial reporting, which consists of control processes designed to provide reasonable assurance regarding the reliability of our financial reporting and the preparation of financial statements in accordance with generally accepted accounting principles in the U.S. To the extent that components of our internal control over financial reporting are included within our disclosure controls and procedures, they are included in the scope of our periodic controls evaluation. Based on our management’s evaluation (with the participation of our principal executive officer and principal financial officer), as of the end of the period covered by this report, our principal executive officer and principal financial officer have concluded that our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended, (the “Exchange Act”) are effective to ensure that information required to be disclosed by us in the reports filed and submitted under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the time periods specified in Securities and Exchange Commission rules and forms and is accumulated and communicated to our management, including our Principal Executive Officer and Principal Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

Management’s Report on Internal Control over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Rule 13a-15(f) under the Exchange Act. Internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external reporting purposes in accordance with generally accepted accounting principles. Internal control over financial reporting includes those policies and procedures that:

·	pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of our assets;

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 are being made only in accordance with authorizations of our management and directors; and

·	provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on the financial statements.

Internal control over financial reporting cannot provide absolute assurance of achieving financial reporting objectives because of its inherent limitations. Internal control over financial reporting is a process that involves human diligence and compliance and is subject to lapses in judgment and breakdowns resulting from human failures. Because of such limitations, there is a risk that material misstatements may not be prevented or detected on a timely basis by internal control over financial reporting.

Management conducted an assessment of the Company’s internal control over financial reporting as of December 31, 2010 based on the framework established by the Committee of Sponsoring Organization (COSO) of the Treadway Commission in Internal Control — Integrated Framework. Based on this assessment, management concluded that, as of December 31, 2010, our internal control over financial reporting was effective.

The effectiveness of the Company’s internal control over financial reporting as of December 31, 2010 has been audited by Deloitte & Touche LLP, an independent registered public accounting firm, as stated in their report which appears herein.

Changes in Internal Control Over Financial Reporting

There were no changes in our internal controls over financial reporting during the fourth quarter of our 2010 fiscal year that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of Silicon Image, Inc.

We have audited the internal control over financial reporting of Silicon Image, Inc. and subsidiaries (the "Company") as of December 31, 2010, 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 maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company's internal control over financial reporting is a process designed by, or under the supervision of, the company's principal executive and principal financial officers, or persons performing similar functions, and effected 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. 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 financial statements.

Because of the inherent limitations of internal control over financial reporting, including the possibility of collusion or improper management override of controls, material misstatements due to error or fraud may not be prevented or detected on a timely basis. Also, projections of any evaluation of the effectiveness of the internal control over financial reporting to future periods are subject to the risk that the 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 Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2010, based on the criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated financial statements as of and for the year ended December 31, 2010 of the Company and our report dated February 16, 2011 expressed an unqualified opinion on those financial statements.
